The upper end of a pillar buoy body is provided with a transmitting antenna, an anchor lamp and a watertight flange of a solar panel. A transmitter module in the buoy body is connected to a multi-way A/D converter through a central processing unit, and the multi-way A/D converter is connected to a temperature chain through cables. The temperature chain which is arranged at the lower part of the buoy body is connected to a watertight socket. Temperature sensors are distributed on the temperature chain at intervals. The utility model can realize long-term, continuous and real-time measurement for the temperature of a fixed point at multiple levels, and the collected value of water temperature is sent back to a coast station in real time after the collected value of the water temperature is processed.

Description

Telethermometer chain

The utility model relates to the temperature of the ocean measuring technique, specifically a kind of Telethermometer chain of measuring multi-level water temperature.

Telethermometer chain can be used for the water temperature long term monitoring in the aquaculture, and conventional approach commonly used is to adopt the on-the-spot regularly measurement of thermometer.In recent years the scallop of culturing as the somewhere 7, August frequent occurrence of large-area the phenomena of mortality, wherein a main cause is because the temperature in waters is undergone mutation or continuous high temperature, caused the death of scallop, how monitoring the water temperature variation at any time is the problem that people pay close attention to always.The present connotative temperature measurement device of existing report in the world is placed on the monitoring that can not realize in the seawater at any time water temperature.

The purpose of this utility model is at above-mentioned existing problems, and a kind of Telethermometer chain that can monitor and be emitted to receiving station at any time to water temperature is provided.

Technical essential of the present utility model is:

The watertight ring flange that emitting antenna, anchor lantern and solar panel are housed is established in pillar buoy body upper end; the transmitter module in the buoy float is connected to multi-channel a/d converter through central processing unit; multi-channel a/d converter connects the temperature chain that the buoy float bottom links to each other by the watertight socket through cable, distributes at a certain distance on the temperature chain temperature sensor is housed.Also be connected with weight and anchor system through wire rope in the buoy float bottom, the wire rope that the buoy float bottom connects weight and anchor system is that the protective casing through being connected clip and temperature chain joins, and also is provided with non-maintaining sour battery and balancing weight in the buoy float.

The utility model can be realized for a long time continuously, fixes a point, be carried out temperature real-time measurement simultaneously at many levels, and the water temperature value of collection is beamed back bank station after treatment in real time.It is simple in structure, is easy to be provided with, and temperature is surveyed the degree of accuracy height, and is easy to utilize.Can be used for the velocity of sound correction in aquaculture, the sonic echo depth finder, the field of utilization, oceanographic engineering etc. again of circulating-water in thermal power plant.

Accompanying drawing is a structural representation of the present utility model.

Among the figure 1 is emitting antenna, and 2 is anchor lantern, and 3 is solar panel; 4 is ring flange, and 5 is transmitter module, and 6 is A/D converter; 7 is cable, and 8 is maintenance-free lead-acid battery, and 9 is balancing weight; 10 is the watertight socket, and 11 is watertight cable, and 12 is protective casing; 13 is the temperature chain, and 14 is that cable is connected clip with wire rope, and 15 is wire rope; 16 is weight, and 17 are anchor system.

Buoy float of the present utility model is mainly used in provides buoyancy, load temperature measuring device and power supply.For making system good at water stability, buoy float can adopt cylindrical structural, and a watertight ring flange is designed in the upper end, in the ring flange upper end antenna, anchor lantern and solar panel is housed; Design a watertight socket in the buoy float lower end, be used to connect cable for measuring temperature.According to experiment showed, of in water, carrying out when buoy float is of a size of the right cylinder of diameter 50cm, height 70cm, stable best in water.It can be for a long time continuously, fixed point, carry out temperature real-time measurement simultaneously at many levels.

Temperature sensor adopts integrated temperature sensor AD590 as temperature-sensing element in the buoy, the AD590 output signal is a current forms, its output current changes with temperature, have antijamming capability strong, be suitable for long-distance transmissions, after the A/D conversion, send transmitter to transmit the data to and dump on the bank on the IBM-PC machine.Maintenance-free lead-acid battery charges to it by solar panel in the buoy.After the bank station receiver received data, real time print went out water temperature value and send IBM-PC machine.Communication modes adopts digital transmission mode, uses the ultrashort wave (USW) communication.

What this cable adopted is the RVVP type cable of crust thickening, and the way that the encapsulation of temperature sensor is adopted is to peel off by that part of cable sheath of encapsulated sensor, chooses the temperature signal line that will connect, the temperature sensor of burn-oning.Outside temperature sensor, put the stainless-steel tube of falling heat-transfer silicone grease in, the stainless-steel tube two ends are sealed get final product then.In order to protect the cable for measuring temperature crust, at cable outside cover one watertight protection sleeve pipe, in order to avoid cable failure.For guaranteeing that as far as possible cable for measuring temperature is vertical, on the direction parallel, a wire rope is housed with the cable direction, hung a weight under the wire rope, wire rope is connected with cable for measuring temperature is active.Adopt the cable for measuring temperature of this method design, can be according to practical use, arbitrary interval encapsulation temperature sensor.In addition, because the influence of being flowed, cable can drift about, and at this moment can encapsulate one or two pressure transducer on cable for measuring temperature, is used to proofread and correct the actual depth of water.
