Description

The invention relates to mechanical engineering, to the technical means used for oceanological works, and can be used for remote undocking of anchored objects or bottom stations.

A remote device for undocking an anchor cable is known, comprising a hollow body with side openings closed by covers of. brittle material, ball lock and stopper [1].

The disadvantage of this device is the limited range of action, determined by the distance at which the shock wave acting on the cover of brittle material has the necessary intensity, as well as insufficient reliability, depending on the strength of the brittle material. .

A remote device for undocking an anchor cable is known, comprising a housing, a hydroacoustic receiver, a power supply _{and a} code command decoder and an actuator including an electric motor, gearbox and a system of locking levers. The device is controlled by code signals, which, entering the decoder, enable the mechanical lock drive that disconnects the lower section of the cable [2].

However, this device is not reliable for a long stay of an anchored object in seawater, since a mechanical lock having .q in its composition movable parts undergoes significant corrosion, which leads to a failure in operation.

The aim of the invention is to increase reliability in operation.

This goal is achieved by the fact that in the device for undocking the anchor cable containing the detachable part of the cable, a sealed enclosure that houses a sonar receiver associated with a code command decoder connected to a power source and an actuator, the latter is made in the form of a cup connected to a detachable part of the cable and 25 connected to the housing by a pin, and coaxially located in the housing of the differential piston with a through central hole, and an electromagnet with a ~ core made in the form of 30 p spring loaded stem.

In addition, the device is equipped with a latch located on the housing, and the spring-loaded rod is made with an annular groove having the ability to interact with the latch.

Figure 1 shows the proposed 5 device, section; figure 2 is a section aa in figure 1; in Fig.Z - node I in Fig.1.

The device comprises a housing 1, a hydro-, acoustic receiver 2, a decoder 3 code commands, a power source 4. The actuator includes an electric. a magnet 5, a rod 6 with a sealing element 7 and a spring 8. A differential pore-15 bus 9 is placed inside the housing 1, having a through hole 10 and a cup 11 fastened to the housing 1 with a destructible pin 12. A latch 13, for example, a plate, is fixed to the electromagnet 5 spring and HMe-jQ with the possibility of displacement of the rod · 6 up to fix the position of the latter by going into the annular groove 14 made on the rod 6. Glass 11. has a central blind hole 25 15, communicating with peripheral holes 16, through which the hydrostatic pressure of the medium is transmitted.

The upper part of the cable 17, which carries the station (object), and the lower detachable part of the cable 18 with a bottom anchor are fixed in the eye 19 of the housing 1 and the glass 11.

The proposed device operates as follows.

The code signal from the surface ship is received by the hydroacoustic receiver 2 and enters the code command decoder 3, which makes the power source 4 connected to the electromagnet winding5. The rod b, / 40 representing the core of the electromagnet 5, is drawn into the electromagnet, compressing the spring 8 ,, and opens the hole 10 in the differential piston 9. In this case, the latch 13 enters the 45 ring groove 14 of the rod 6. Outboard water entering through the hole 10 into the inner the cavity of the housing 1, aligns the internal pressure with the external. fifty

Since the inner diameter D of the differential piston 9 is larger than the outer diameter d, the piston 9 moves downward due to the difference in forces from hydrostatic pressure on its ends 55, cuts the destructible pin 12 and pushes the glass 11, on which the detachable part of the cable 18 with the anchor is fixed, from the housing 1.

After that, the station (object), bonded to the upper part of the cable 17 and having positive buoyancy, floats to the surface.

In case of accidental violation of the tightness of the sealing element 7 and the ingress of water outside the inside of the housing 1, the device automatically separates, as described above.

The use of hydrostatic pressure for undocking can significantly increase the load-bearing capacity of the device. The remote device for undocking the anchor cable, in which the actuator is protected from the effects of the marine environment, is capable of functioning at various depths for a long time, provides reliable undocking of anchored objects, and also allows you to significantly increase the load on the docking station.
