The equipment works in four working modes of oiling, oil receiving, oil distributing and tank dumping, and the specific working process is as follows (the two oil tanks 1 are respectively called as an oil tank A and an oil tank B):

an oil filling mode:

taking the example of using aviation fuel stored in the tank a for refueling, the valve i, the valve ii 8, and the valve iii 9 are all closed, so that a passage is formed between the fuel supply pipe 18 and the fuel outlet pipe 13 on the tank a; so that the passage between the oil receiving nipple 26 to the oil supply pipe 18 is closed; so that the passage between the return line 29 to the filter separator 22 is closed.

That is, in the refueling mode, the refueling passage in the scheme is oil tank A-oil outlet pipe 13-common oil supply pipe 19-oil supply pipe 18-oil pump 20-first connecting pipe 21-filter separator 22-second connecting pipe 23-flow meter 24-gravity oil filling pipe 12 or pressure oil filling pipe 11-gravity oil filling gun or pressure refueling joint, aviation oil is finally discharged from the gravity oil filling gun or pressure refueling joint through the refueling passage to refuel the aircraft, and two refueling modes of gravity refueling or pressure refueling can be selected according to different situations.

The filtering separator 22 is used for filtering impurities in the aviation oil, the flow meter 24 is used for monitoring the aviation oil flow in the whole oiling passage, and when the deviation between the flow in the oiling passage displayed by the flow meter 24 and the actually required flow is large in the working process, oiling is required to be stopped and overhaul is carried out.

An oil receiving mode:

taking the case that the refueling truck delivers the aviation fuel into the oil tank a as an example, the passage between the fuel receiving connector 26 and the fuel pump 20 is opened, the passage between the fuel pump 20 and the fuel supply pipe 18 is closed, the passage between the filter separator 22 and the fuel return pipe 29 is opened, and the passage between the filter separator 22 and the flow meter 24 is closed, that is, in the fuel receiving mode, the fuel receiving passage in the present embodiment is the refueling truck-fuel receiving connector 26-the fuel pump 20-the first connecting pipe 21-the filter separator 22-the fuel return pipe 29-the fuel inlet common pipe 16-the fuel inlet pipe 17-the oil tank a, and the aviation fuel in the refueling truck can enter the oil tank a through the fuel receiving passage.

Oil-dispensing mode:

taking the case of conveying the aviation fuel in the oil tank a to the refueling truck as an example, the flow meter 24 is closed to the gravity refueling unit and the pressure refueling unit, and the delivery connection is connected to the oil truck, where the delivery connection is the oil tank a-the oil outlet pipe 13-the common oil supply pipe 19-the oil supply pipe 18-the oil pump 20-the first connection pipe 21-the filter separator 22-the second connection pipe 23-the flow meter 24-the delivery pipe 25-the delivery connection-the oil truck, and the oil passes through the delivery connection and finally enters the oil truck through the delivery connection.

A tank switching mode:

when the aviation oil in the oil tank A needs to be emptied and overhauled, the passages between the filtering separator 22 and the gravity oiling unit, the pressure oiling unit and the oil distributing joint are closed. If the aviation fuel amount in the oil tank A is more, the residual aviation fuel in the oil tank A needs to be discharged into the oil tank B, and the oil circulation path is as follows: the oil tank A, the oil outlet pipe 13, the oil supply common pipe 19, the oil supply pipe 18, the oil pump 20, the first connecting pipe 21, the filtering separator 22, the oil return pipe 29, the oil inlet common pipe 16, the oil inlet pipe 17 and the oil tank B can be used as usual after aviation oil is discharged into the oil tank B, and the oil tank B can not be used for a long time due to maintenance. During the tank dumping process, the oil return pump 20 is started, so that the passage from the second closed-circuit sampler 27 to the filtering separator 22 can be opened at regular time, and the aviation oil which is about to enter the oil tank B is sampled and detected through the second closed-circuit sampler 27.

Because the oil outlet pipe 13 is communicated with the lower part of the end surface of the oil tank 1, when the height of the residual aviation fuel in the oil tank 1 is lower than that of the oil outlet pipe 13, the fact that the aviation fuel in the oil tank 1 is less at the moment is shown, and the tank pouring is stopped. The valve I in the emptying pipe 2 on the oil tank A is opened, the valve III 9 on the side is opened at the same time, and the valve II 8 on the side is closed, so that aviation oil in the oil tank A enters the first closed-circuit sampler 5 after passing through the emptying pipe 2 and the sampling branch pipe 4, an operator can observe the quality of the aviation oil in the first closed-circuit sampler 5, and after sampling detection, the aviation oil remained in the sampling branch pipe 4 is discharged into the first quality detection tank 6. At this point, the valve iii 9 is closed, and the valve ii 8 on that side is opened, and the aviation fuel remaining in the tank a is discharged into the first quality inspection tank 6 through the emptying branch 3. At this time, the operator can perform quality detection on the aviation fuel in the first quality detection tank 6, and then judge whether the part of aviation fuel can be used continuously.

The working process of the security mechanism in the embodiment is as follows: the security personnel can go up 1 top of oil tank and look over or overhaul oil tank 1 in rail 30 through staircase 31, can effectively solve the potential safety hazard that security personnel overhaul in-process exists, and oil tank 1 top is equipped with back-fire relief breather valve 33, the manhole cover 32 of emergent pressure release that are used for maintaining the air pressure balance in the oil tank 1 simultaneously, is used for detecting the level gauge of liquid level height in the oil tank 1 to ensure the security of oil tank 1 in the course of the work.

In this embodiment, a plurality of oil storage devices only need set up one set of oil supply unit can, simplify the structure, and when one of them oil tank 1 overhauls, only need the valve on the adjustment oil tank 1 open and close the condition can change other oil tanks 1 and carry out the oil feed, convenient operation, convenient to overhaul, and through the oil storage capacity of the large-scale airport of a plurality of oil tanks 1 increase to emergent the use.

Example 3

This embodiment is on embodiment 1's basis, through the operation of integrated controller control whole security protection system, specifically as follows:

as shown in fig. 7, the security system further includes an electro-hydraulic valve connected to the oil outlet end of the oil pump 20 and used for controlling the opening and closing of the oil outlet end of the oil pump 20, and the electro-hydraulic valve is further connected to a dead demann control handle. When the oil supply device is used, the dead man control handle is used for locking an operator in a certain range near the oil supply device, so that when a safety fault occurs, the operator can cut off a passage through the electro-hydraulic valve as soon as possible, and the influence caused by the safety fault is reduced or eliminated as much as possible.

The security system further comprises a master controller and an acousto-optic alarm, the master controller and the acousto-optic alarm are located outside the oil tank 1, the input end of the master controller is electrically connected with the liquid level monitoring part (the magnetostrictive liquid level meter 34 and/or the liquid level switch 35) and the Daiman control handle respectively to receive signals sent by the devices, and the output end of the master controller is electrically connected with the acousto-optic alarm, the emergency stop switch of the oil pump 20 and the electro-hydraulic valve respectively to output control signals. The connection part of the oil tank 1 and/or the oil outlet pipe 13 and the oil tank 1 is also provided with a combustible gas detector for detecting whether combustible gas leakage occurs outside the oil tank 1, and the combustible gas detector is electrically connected with the master controller. The oil tank 1 is connected with an electrostatic grounding controller which is electrically connected with the master controller.

The master controller is used for receiving signals sent by the liquid level monitoring device, the audible and visual alarm and the dead man control handle so as to carry out security protection control on the input or output of the oil tank 1. Specifically, two oil tanks 1 (oil tank a and oil tank B) are taken as an example for description, magnetostrictive liquid level meters 34 (respectively a liquid level meter a and a liquid level meter B) for measuring the liquid level of aviation oil are installed at the tops of the oil tanks a and the oil tank B, a master controller can acquire liquid level signals and temperature signals of the liquid level meters a and B in real time in the working state of each oil tank 1, convert the liquid level value into a volume value through calculation of a chip of the master controller, and can be connected with a display outside the oil tank 1 and display the empty volume, the apparent volume, the oil temperature and the oil height in each cabin on the display; the upper parts of the inner walls of the oil tank A and the oil tank B can be respectively provided with a liquid level switch A and a liquid level switch B which are slightly lower than the liquid level meters. When the aircraft fuel tank is used, when the liquid level of the aircraft fuel in each tank reaches or exceeds each liquid level switch 35, each liquid level switch 35 is in communication connection with the master controller, the master controller outputs an alarm signal to the audible and visual alarm to send audible and visual prompts, and the master controller controls the emergency stop switch to close the oil pump 20 to stop running so as to protect the whole oil tank 1; the operating principle of each level gauge is roughly the same with level switch 35's operating principle, also with signal transmission to master controller in order to control oil pump 20 to close when arriving the level gauge height on aviation oil surface, the purpose of setting up each level gauge is to form double insurance warning chain control with level switch 35, can effectively avoid the potential safety hazard that oil pump 20 continued work when level switch 35 breaks down and produces.

The combustible gas detector is used for monitoring the concentration of oil gas outside the oil tank 1, when the combustible gas is monitored to exceed a set value, the combustible gas detector outputs a signal to the master controller, meanwhile, the master controller sends an alarm signal to the audible and visual alarm to send an audible and visual prompt, and the master controller controls the emergency stop switch to close the oil pump 20 to stop running so as to protect the whole oil tank 1. When the unreliable condition of ground connection appears in the electrostatic grounding controller, alarm signal transmission to total controller, and then control audible-visual annunciator in order to send audible-visual suggestion, total controller control emergency stop switch closes oil pump 20 simultaneously, makes its stall.

When the input end of the master controller is electrically connected with the dead man control handle and the output end of the master controller is electrically connected with the electro-hydraulic valve, the master controller is used for receiving signals sent by the dead man control handle and controlling the electro-hydraulic valve. The dead man control handle can control the oil unloading and adding operation within a certain range along with people. Specifically, when the aviation oil supply equipment unloads and refuels, an operator presses the dead man control handle, the master controller receives a signal sent by the dead man control handle and transmits the signal to the electro-hydraulic valve, the electro-hydraulic valve is opened, the oil path is opened, the aviation oil supply equipment starts unloading and refuelling work, when the operator temporarily leaves a work post in a special situation, the dead man control handle needs to be loosened, the master controller receives the signal sent by the dead man control handle and transmits the signal to the electro-hydraulic valve, the electro-hydraulic valve is closed, the oil path is closed, and the aviation oil supply equipment stops unloading and refuelling work. In addition, in the normal oil unloading process, the dead demann control handle needs to be loosened within a period of time and then pressed down for restarting, so that the operator is prevented from separating from a working post, and the safety of the whole operation process is ensured. Meanwhile, a circuit for connecting the dead man control handle and the master controller is also provided with a control button exceeding the dead man, and if the dead man control handle fails, the control button can be used for starting and stopping emergency control operation by exceeding the dead man. The specific structure of the deadman control handle and the electrohydraulic valve is a structure in deadman control commonly adopted by the existing aircraft refueling truck, or a structure of the deadman handle, the control circuit and the electromagnetic directional valve (or a model of the deadman control added) disclosed in a chinese patent "a logic time sequence intelligent control deadman refueling system" with the publication number of CNCN201350975Y is adopted, which belongs to the prior art, and therefore, the specific structure is not described again here.
