B.A.SHTEPHAN'S DISCONNECTOR FOR RETURNED UNDERWATER

The technical solution relates to devices for fastening and separating pop-up buoys and can be used as a disconnector for returned underwater objects, for example, bottom beacons-transponders of hydroacoustic navigation systems, bottom seismic stations and other technical equipment returned to the surface.

Known circuit breakers 3 to 5 with a trip device from a timer command signal, wherein the actuator of the circuit breaker can be made in the form of electrochemical, pyrotechnic or electromechanical blocks. A common feature of such breakers is the presence of a housing with an actuator fixed to it.

However, in some cases, breakers of this type are not sufficiently reliable 5, therefore, as a command signal, as a rule, 2 - 3 hydroacoustic command signals are used to ascend from the supply vessel, while the mechanical breaker is triggered by the converted hydroacoustic signal in the electronic circuit of the breaker.

However, the reliability of switches of this type is also not always satisfactory, which requires 1, 4 the combined use of several devices for opening various types.

OBJECTS

duplication of various nodes of mechanical opening devices, or by introducing additional elements into the disconnector (for example, buoy 1 forced ejection nodes).

The prototype device 1 for mounting and separating a pop-up buoy includes a housing with an actuating mechanism for disconnecting it, which includes grips and locks made in the form of rotary shields, hooks, power and return springs, latches, and other mechanical and electrical (electromagnet) assemblies.

The design of device 1 cannot be considered rational in accordance with the criterion “complexity - cost - efficiency. The reliability of the device 1, as with other analogues, in some cases, is insufficient due to the presence of many interacting parts, which could be eliminated through the use of a single control element.

The essence of the proposed technical solution is to create a circuit breaker for returned underwater objects, in which for the opening process a number of nodes are replaced by one control element with an elastic control membrane.

The main technical result is to simplify the design of the circuit breaker while increasing its reliability and reducing cost, which allows for a more rational device in accordance with the complex criterion of “complexity - cost - efficiency.

The technical result is achieved as follows.

The circuit breaker for returned underwater objects comprises a housing with an actuating mechanism for opening and gripping fixed thereto.

The disconnector B.A.Stefan is characterized in that the actuator is located in two boxes with dielectric fluid symmetrically fixed with screws on the housing, the grip is made in the form of a hook equipped with a swivel in the lower part in the form of a swivel plate. In this case, the actuating trip mechanism includes an electromagnet with

a movable retraction rod and rollers at its end, a membrane connected to the rod and fixed in the box with a perforated nut, an elastic compensator, as well as a spring and feedback sensor. Moreover, the boxes are equipped with plugs for pouring dielectric fluid, the covers of the boxes have channels for connecting to the external marine environment, and the body has a channel for supplying a command signal for opening to the electromagnet and a feedback signal about the execution of the opening command.

The disconnector is also characterized in that the screws for securing the boxes of the actuators and plugs for filling the dielectric fluid are equipped with sealing elements.

In FIG. 1 shows the general view; the first view of the proposed circuit breaker, figure 2 is a section along A - A.

The disconnector comprises a housing 1, boxes 2, a hook 3, a swivel 4, an electromagnet 5 with a rod 6 and rollers 7, a membrane 8 with a perforated nut 9, an elastic compensator 10, plugs 11, a spring 12, a feedback sensor 13, sealing elements 14 and 15 , screws 16 securing the boxes, the channel 17 of the housing, channels 18 and 20 of the connection with the external environment and the cover 19 of the boxes.

The operation of the circuit breaker B.A. Stefan is as follows.

The threaded end of the disconnector is attached to the returned device, and by hook 3 to the rope (position K, figure 2), which is connected to the load holding the device with positive buoyancy at the bottom of the sea. A loop of the rope is inserted into the slot of the housing 1 (Fig. 2) with the hook 3 taken to the side. After that, the hook 3 is pressed tightly against the housing 1, compressing the spring 12. The swivel 4, freely rotating on the lower axis of the hook 3, is in a position perpendicular to it . When breeding the rods 6 of the electromagnets 5 in different directions of the membrane 8 bend, turning the swivel 4 by 90 ° and lowering the rods 6, which the rollers 7 fix it in its original position due to the return force of the membrane 8.

The device from the side of the vessel sinks into the water, and then the load is dropped with a long rope attached to it and carries the device to the bottom.

When a current pulse is applied, the movable rods 6 of the electromagnets 5 are pulled inward of the coils, freeing the swivel 4. The spring 3 hooks to the side, freeing the rope, and the lifting force of the apparatus pushes it to the surface. If any of the electromagnets 5 does not work, then the swivel 4 will still rotate on the axis and release the hook 3 from engagement.

When retracting the rods 6, the membrane 8 bends, pushing the dielectric fluid from the cavity A (Fig. 1) through the corresponding channels into the cavity of the box 2. Part of the liquid located in the cavity B is also pushed out by the rods 6. The increase in the volume of liquid found in the cavities of the boxes 2, is aligned due to the elastic deformation of the compensators 10.

With the aid of a sensor 13 mounted in the housing 1 of the circuit breaker, a feedback signal is received on board the vessel that the circuit breaker has tripped.

Thus, a special design of the circuit breaker implements load symmetry when replacing a number of nodes with one element of an elastic control membrane. When simplifying the design, B.A.Stefan’s breaker has greater reliability and lower cost in comparison with analogues and prototype, which allows to implement a more rational device in accordance with the complex criterion “complexity - cost - efficiency.
