Description

The utility model relates to the field of diving technology, namely to the means of transportation of divers in the aquatic environment. The device can be used in the surface and underwater position, as it is equipped with a means of regulating buoyancy, which allows you to get rid of trim ballast, change the length and displacement of the towing vehicle. The device may be used in military equipment, tourism, when rescuing on the water.

Numerous designs of foreign and domestic towers of the back and chest type are known. Domestic towing vehicles such as Proton, Proteus, Proteus-2, Neptune, Tuna, as well as foreign towers Pegasus, Cousteau, Marlin, which have a predominantly cylindrical shape mounted on the outer surface peripheral devices: shoulder rests, handrails, fairing, saddle and mover located coaxially to the housing or on an arm outside the housing, which negatively affects the characteristics of the device, makes it difficult to control. Known patents are: RU No. 2153438 C1, IPC B63C 11/00, where the diver’s means of movement contains a sturdy case with handles, a rowing electric motor and a propulsion system, a longitudinal partition with a bulkhead is made in the aft part of the case, the rowing electric motor is installed in the baffle within the longitudinal dimensional body , the towbar is equipped with skid supports made in one with the handles; RU No. 188198 U1, IPC В63С 11/02 where the chest tow contains a cylindrical body, a drive motor installed inside the body and a mover located coaxially with the body, as well as peripheral devices located on the body; RU No. 2330782 C2, MPK V63C 11/46, where the back-tow diver has a sturdy cylindrical body, contains a battery and a rowing motor equipped with an inguinal and shoulder rests for fastening on the diver’s body, the drawback of the towing device is a remote console with peripheral devices above the diver’s head.

All of the above diving equipment is used by light divers for underwater work and has common drawbacks: trim ballast, which affects the length of the towing hull, remote peripherals that create additional hydrodynamic resistance, a large mid-section, affecting the fatigue of divers and single-function.

The closest in technical essence is an individual device for swimming, patent RU 2552758 C1, IPC АВВ 35/08, В63С 11/46, ВВВ 35/73 published June 10, 2015, which contains a housing made with the possibility of mechanical connection with a gas source and with a means of regulating buoyancy, contains a handle for holding the device, a towing device connected to the housing and containing one propeller, a course-keeping means characterized in that it has a streamlined body with integrated peripheral devices and modules, attached to the case.

The main disadvantage is the narrowly functional focus, which consists in the delivery of one diver.

The objective of the proposed utility model is to create a multifunctional modular towing vehicle with the possibility of using it in underwater and semi-submerged conditions and expanding the tasks performed.

The technical result is the creation of a streamlined hull, equipped with a buoyancy control device and peripheral devices built into the hull, and modules connected to the hull and expanding the range of tasks: delivery of one diver, delivery of two divers, cargo delivery, when using the stern or one of them bow modules, towing a trailer module, delivery of three or four divers using a special bow module, delivery of injured underwater or semi-submerged condition.

The problem is achieved in that the set of the towing diver containing the hull, made with the possibility of mechanical connection with a gas source and with a means of regulating buoyancy, contains a handle for holding the device, towing means connected to the hull and containing one propeller, means of maintaining the course, a streamlined housing with integrated peripherals and modules connected to the housing have been introduced, expanding the range of tasks.

The weight of the set of diving equipment, with a back or chest breathing apparatus, is approximately 40 kg, the mass of the proposed model of the towing vehicle in the air is 60 kg, length 1.5 m, width 0.45 m, speed up to 6 knots, cruising range up to 10 miles time 4 hours of operation, when using modules, the speed of movement is up to 5 knots, the operating time is 3 hours.

A diver in equipment can use semi-submerged and underwater movement at depths of up to 60 meters with appropriate training, when using the proposed model of a modular towing vehicle, he gets the opportunity, without special equipment, to get ashore on his own, and when using additional modules to deliver cargo or injured. When using an underwater scooter of a towing vehicle, the flow rate of the respiratory mixture by a diver is significantly reduced, which allows it to increase the time spent under water.

The essence of the utility model is illustrated in FIG. 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, which shows an underwater scooter towing vehicle (PSB) and additional modules that are installed depending on the task:

FIG. 10 - general view of the PSB from the stern;

FIG. 11 is a general view of the PSB with a special nose module;

FIG. 12 is a general view of the PSB with the bow and stern module.

To achieve a technical result, the towing body 1 is made of an aluminum anti-corrosion alloy and has a streamlined shape, which allows to reduce the resistance of the aquatic environment. The nose is made narrowed complex shape in several curved planes. The lower part of the nose goes into a narrow area, passing under the center of the body and performs the function of a keel 2. In the central part, recesses are provided on the sides for installing lighting devices 3. The upper gentle part smoothly passes into the shallow nose fairing 4, made transparent. Under the fairing, a sealed instrument panel 5, consisting of a light indicator showing the discharge of the batteries; buoyancy control indicator; speed indicator; underwater navigation and search panel; communication devices; remote control devices. Deck part 6 has a flat surface, beveled to the stern for ease of placement of the diver. A circular rotary two-section nozzle 7 is installed on the aft wall, designed to deviate the water flow from the direction of movement, a water jet propulsion 8 located in the stern tube 9 and connected through the propeller shaft 10 to the electric motor 11, the nozzle channel 12 is made narrower to improve flow parameters. A water intake guide element 13 is installed on the bottom. Improved aerodynamic shape gives balanced stability and maneuverability during movement. The buoyancy control system has a thin-walled gas storage cylinder 14, which is located in the center of gravity, located below the buoyancy center, and serves to give the specified stability. The control levers right 15 and left 16 are located on the housing 1 and are equipped with an on / off button and buttons for starting the engine, buoyancy control, and water jet nozzle control, which allows you to stably maintain a given course. During operation, the fingers on the buttons are naturally placed. The start button (not shown conventionally) of the electric motor 11 is located next to the right handle 15 under the thumb of the right hand, when the button is pressed and held, the electric motor 11 starts, by short-term pressing the towing speed will increase by one step, by double-short pressing the towing speed will decrease by one step, on the speed indicator, when the steps are switched, the LEDs light up. The buoyancy control button is located next to the left handle 16 under the thumb of the left hand, when pressed and held, the necessary buoyancy is achieved, when pressed again, the ballast zone is drained using a gas cylinder through special valves and the scooter acquires neutral buoyancy. Under the buoyancy control button there is a button joystick for controlling the nozzle 7; when maneuvering, the part of the nozzle 7 is rotated with the button joystick, which ensures a change in the direction of the thrust vector.

The scooter underwater scooter is driven by one person who holds the control handles 15 and 16, his body is located above the aft part of the PSB, without interfering with the operation of the water-jet propulsion 8. The diver should always take a horizontal position that contributes to the minimum water resistance to obtain maximum speed, in this position provides good visibility to the dashboard 5 with indicators. PBS is equipped with a nose module 17 with a luggage compartment 18, aft module 19 with a luggage compartment 20 and a special nose module 21 with a luggage compartment 22 and smoothness stabilizers 23.

PSB is an individual means of delivery, but if it is necessary to deliver two divers, the feed module 19 is used, the second person holds onto the special folding handles 24 and is located above the driver, so the PSB becomes a group carrier for divers.

To solve the problems of cargo transportation, it is possible to use the bow 17 and stern module 19 using their luggage compartments 18 and 20. With a large load, a special bow module 21 is used, which, in addition to the luggage compartment 22, has stabilizers of smooth movement 23 or “wings”, the load can be fixed on the “wings” with a varying area of 25 under special tightening grids 26. Smooth motion stabilizers 23 reduce traction to the surface of the water at high speed and allow you to keep course under water.

When deciding on the delivery of three divers, a special nose module 21 is also used, while the divers are located on the “wings” 23, holding on to the handrails 27 and hiding behind the transparent fairings 28. Such a scheme loses hydrodynamically, but provides contact between the driver and passengers. If necessary, the delivery of four divers attached feed module 19 with folding arms 24.

Engine power allows you to tow a container with a significant amount of cargo, the container may contain additional batteries and spare gas sources.
