Description

The invention relates to the field of marine engineering and can be used to create deep-sea drifting instruments and samples of naval weapons.

Deep-sea objects and instruments are known (instruments for studying the ecology, properties of the World Ocean, marine weapons, etc.), the stabilization of the drift depth of which is ensured by the controlled intake or discharge of ballast sea water.

To maintain a given drift depth, objects are equipped with complex measurement and control systems, which require a large consumption of energy reserves, limiting the total drift time, especially for large depths of use.

Autonomous objects are known for medium and large depths, designed to distinguish research work at great depths. Among them, the apparatus of Yu.A. Shimansky should be noted (see Epron, collection XXIII-XXIV, 1938), intended for work at a large (2500 m) depth. The device is made in the form of a cylinder of large elongation with a battery, control devices and a system for maintaining zero buoyancy with liquid and solid ballast. The device is designed to work for 10 hours. Various bathyscaphes controlled by propellers are also known (Triest, Archimedes, Sever-1, etc., see. Underwater vehicles M.N. Diomidov, A.N. Dmitriev, Shipbuilding, Leningrad, 1966).

An automatic floating mine is known in defense technology (see “Mine-sweeping weapons”, K.V. Morozov, M., 1974), the stabilization device of which is made in the form of an electric motor that rotates the propeller and is controlled by a hydrostatic device from outboard water pressure .

The main disadvantage of these devices is the high energy consumption, which leads to a short duration of functioning of the drifting device.

A device for stabilizing the depth of a deep-sea drifting device (see application for invention No. 2003115768/11 (016754) dated 05/27/2003).

The device comprises a pressure sensor, a control system, an electric motor switch mechanically connected to the working body, and a storage battery, the working body being made in the form of a hydraulic pump pumping and pumping outboard water into a ballast chamber connected by a piping and valve system with a high-pressure air cylinder and through safety valve with overboard medium.

The specified device adopted by the authors for the prototype of the invention.

All of the above devices to ensure drift at a given depth require periodic inclusion of an electric motor with a working body, i.e. high consumption of energy reserves, and for the device adopted by the authors as a prototype of the invention, also the consumption of high pressure air reserves to maintain a given pressure in the ballast chamber. These shortcomings are exacerbated with a significant increase in the drift depth.

The aim of the invention is to increase the time and depth of the drift of the device, as well as ensuring its functioning during multiple cycles of immersion-drift-ascent.

This goal is ensured by the fact that in the device for stabilizing the depth of a deep-sea drift device comprising a pressure sensor, a storage battery, a control system, an electric motor switch mechanically connected to the hydraulic pump, and a ballast chamber, the plunger type hydraulic pump is equipped with a valve distributor, pipelines connected to the outboard medium, and a ballast chamber, which is connected to the outboard medium through a valve with a throttle device, and all solenoid valves are signal-connected to the system control, and in parallel with the ballast chamber, a hydraulic cylinder supported on an elastic base is connected to the outboard medium through an electrovalve.

These signs provide the minimum power consumption for multiple cycles of operation (immersion-drift-ascent) of a deep-sea drift device.

The device is schematically depicted in the drawing, where the pressure sensor (1), the battery (2), the control system (3), the switch (4) of the electric motor (5), the plunger hydraulic pump (6) with valve distribution (7), and the piping system are indicated (8) connected to the outboard medium and to the ballast chamber (9) connected to the outboard medium through an electrovalve (11) with a throttle device (10); a hydraulic cylinder (13) is installed separately with a piston (14) supported on an elastic base, the hydraulic cylinder cavity is connected to the outboard medium through an electrovalve (12). All valves 11 and 12 are signal-connected to the control system (3).

The device operates as follows. The initial position of the device is swimming at the sea surface, the buoyancy of the device is positive. At the command of the control system unit 3, which received the signal from the pressure sensor 1, the solenoid valve with a throttle device 11 opens and overboard water by gravity fills the ballast chamber 9, the buoyancy of the device decreases, it becomes negative, the device begins to deepen. The pressure sensor registers an increase in depth, and the control system, analyzing the depth and the rate of change according to a given control algorithm, periodically opens either a valve 11 with a throttle 10 to further fill the ballast chamber 9, or gives a command to start an electric motor with a hydraulic pump 6, outboard water is drained from the ballast chamber. In the absence of commands from the control system, valves 11 and 12 are closed.

When deepening the product through an open solenoid valve 12, hydraulic cylinder 13 under the piston 14, compressing a specially calibrated elastic system, receives overboard water, which partially compensates for the increase in buoyancy of the device depending on changes in density, temperature and salinity of the water. When surfacing - on the contrary, the elastic system, acting on the piston, squeezes water from the hydraulic cylinder. Thus, this system partially compensates for the change in the buoyancy of the device, which reduces the required number of cycles and the turn-on time of electrical appliances and thereby reduces energy consumption.

According to the proposed invention, the calculation work and bench testing of the hydraulic circuit of the device.
