Description

The invention relates to devices for fastening and separating small objects, in particular buoys, from a high-speed underwater object (hereinafter - software).

Known separation devices, the actuator of which can be made in the form of hydrostatic [1, 2], pyrotechnic [3] or electromechanical [4-7] blocks. However, the reliability of such circuit breakers is not always satisfactory due to the duplication of various nodes and the introduction of additional electronic units, and, as a consequence, the complexity of the design.

A device is known, "The disconnector B.A. Stefan for returned underwater objects ”[8], in which one element is used for the opening process - an elastic control membrane. The actuator of this circuit breaker is placed in two symmetrically fixed boxes with dielectric fluid, the grip is made in the form of a hook equipped with a swivel in the form of a rotary bar in the lower part, while the actuator of the opening includes an electromagnet with a movable retraction rod and rollers at its end, a membrane connected with a rod and a perforated nut fixed in the box, an elastic compensator, as well as a spring and a feedback sensor, the housing 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 device is designed to lift the device with positive buoyancy from the bottom of the sea, does not have a push mechanism and is not intended to separate the buoy from the underwater vehicle, moving at high speed.

Also known is the device "Disconnector for returned underwater vehicles" [9], used for returned underwater objects, containing an actuator including a solenoid and a reed switch, as well as a lever mechanism consisting of a tilt lever pivotally connected to the fork of the pusher mechanism. In addition, the housing-housing of the trigger mechanism is equipped with a communication connector with a control device for supplying power to the coils of the solenoid and reed switch, as well as for transmitting a command signal for opening and a feedback signal about the execution of the opening command. The described circuit breaker is not equipped with a forced ejection mechanism, which may complicate separation when applied to moving software.

It is also known "The device for mounting and separating the pop-up buoy on the underwater technical means" [10], which contains a housing with locking devices, lever mechanisms for pushing the buoy and the mechanism for fastening-separating the buoy and chopping off the electric cable. Locking devices are made in the form of rotary shields with blocks of buoyancy, grips and elastic gaskets. The levers of the buoy's forced ejection mechanism are mounted on sealed rotary tubes with rollers located inside with torsion springs protected against corrosion. The mechanism for fastening-separating the buoy and chopping off the cable is installed in a removable housing unit. This device, designed to release the buoy during the movement of the underwater technical means, having a mechanism for forcing the buoy, is selected as a prototype.

The disadvantage of the prototype is the use of a squib for cutting the electric cable supplied to the buoy, that is, only a single use of the separation device is possible, which complicates routine maintenance and checking the operation of the buoy, increasing the cost of production.

The objective of the invention is to reduce the cost of production due to the possibility of multiple recharging of the separation device, simplifying and increasing the reliability of the design of the device, while maintaining the ability to separate the buoy from the software at high speed.

The problem is solved by the fact that the buoy is fixed in the software housing with the help of special holders, the device includes a mechanism for forcing buoy pushing out, and its inclusion and synchronization of the software and buoy time counters is provided wirelessly, for example, electromagnetic or optical.

The device consists of (see Fig. 1):

1 - housing;

2 - translational actuators;

3 - stocks;

4, 6, 7, 8 - compression springs;

5 - holders;

9 - stops;

10 - devices for wireless inclusion and synchronization of time counters for software and buoy;

11 - detachable buoy.

The housing 1 can be combined with the software housing and ensures the tightness of the internal volume of the device. The buoy forced ejection mechanism includes actuators 2, for example, of an electromagnetic type, providing translational movement of the rods 3 in the direction A. The rods 3 are designed to fix the holders 5, the springs 4 provide a return movement of the rods 3 to their original position. The holders 5 are designed to fix the detachable buoy 11 in the housing 1. The springs 6 provide translational movement of the holders 5 in the direction B, which releases the detachable buoy 11 for movement from the housing 1 in the direction B. The stops 9 prevent the holders 5 from falling out of the housing 1. The device 10, for example, electromagnetic or optical type, provides the inclusion of detachable buoy 11 immediately before its separation and the synchronization of time counters and buoy.

The initial (charged) state of the device is shown in FIG. 1. Detachable buoy 11 is fixed in the housing 1 by means of holders 5, while the springs 7 and 8 are in a compressed state. The holders 5 tighten the springs 6, and their position is blocked by the rods 3, which are inserted into the cylindrical grooves of the housing 1. In this case, the stiffness of the springs 4 is selected in such a way as to prevent spontaneous release of the rods 3 from the grooves on the holders 5.

The number of actuators 2, rods 3, holders 5, springs 4 and 6 and stops 9 and the stiffness of the springs 6 are selected so as to ensure reliable fastening of the detachable buoy 11 in the housing 1 and the absence of distortions and jamming when the device is triggered.

The principle of operation of the device is as follows.

The device 10 receives a command to turn on a detachable buoy 11 and synchronize its time counter with a software time counter. Further, the actuating signal 2 is synchronously fed to the actuators 2, as a result of which the rods 3 move in the direction A, overcoming the elastic forces of the springs 4, and thereby releasing the holders 5. The latter, under the action of the elastic forces of the springs 6, move in the direction B until they collide with the stops 9, as a result, the detachable buoy 11 is released and, under the action of the elastic force of the springs 7 and 8, moves in the direction B. In this case, the parameters of the springs 7 and 8, as well as their number, are selected from the condition that the detachable buoy 11 should exit at least half of the housing 1 buoy length 11.

As a result, the objectives of the claimed invention are solved.
