Description

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.

Since the breakers are part of the returned underwater vehicles, they are patented, as a rule, together with aquazondes and / or displacer stations. Recently, a number of patents have been obtained in the Russian Federation for such technical solutions: technology for setting up a submerged buoy [9], an autonomous oceanographic probe [8], hydroacoustic buoys [6, 7] with hydrostatic breakers, a complex [4] for lifting sunken objects, a device [ 3] lifting the object from the bottom of the reservoir, underwater breakers as part of the hydrophysical and oceanographic stations [2, 5], a breaker [1] for returned underwater objects.

A common feature of such breakers is the presence of a housing with an actuating release mechanism and a grip fixed thereto. Known circuit breakers with a trigger device for a hydroacoustic signal or for a command signal of a programmed timer can be made in the form of hydrostatic [6, 8], pyrotechnic [7] or, more often, electromechanical [2-5] blocks.

However, the reliability of the known circuit breakers is not always satisfactory [1]. Duplication of various nodes and the introduction of additional electronic units (which can be placed directly in the probe housing) [2] complicates the design.

The electromechanical switch for returning underwater vehicles according to the patent RU 38154 U1, 05.27.2004 [1], adopted as a prototype, contains a housing with an actuating mechanism for locking and gripping it, the actuating mechanism comprising an electromagnet with a movable retractor rod and a feedback sensor, and the housing has a connector for supplying a command signal to the electromagnet and a feedback signal about the execution of the opening command. In the device [1], the opening actuator is located in two (duplicating) boxes with dielectric fluid symmetrically fixed with screws on the housing, and the gripper is made in the form of a hook-lock equipped with a swivel in the lower part in the form of a rotary rod. At the same time, the screws for fastening the boxes of the actuator and the plugs for filling the dielectric fluid are equipped with sealing sealing elements.

A disadvantage of the known circuit breaker [1] is the relative complexity of the design (the use of chamber boxes with dielectric fluid isolated from the external environment) and the low reliability due to the presence of seals (glands).

The essence of the proposed technical solution is to create a circuit breaker for returned underwater vehicles, in which insufficiently reliable sealing elements are excluded.

The main technical result is the simplification of the circuit breaker while increasing its reliability, which allows for a simpler rational design, isolated from the external environment and providing a high degree of failure-free operation of the gripper.

The technical result is achieved as follows.

The disconnector for returning underwater vehicles contains a housing with an actuating release mechanism and a grip fixed to it, the actuating opening mechanism comprising an electromagnet with a movable retraction rod and a feedback sensor, and the housing has a connector for supplying a command signal to the electromagnet and a feedback signal on the execution of the opening command .

A distinctive feature of the disconnector is that the actuating mechanism of the opening, located in the housing-casing, including the solenoid and the reed switch, is made in the form of a trigger-filled compound and completely isolated from the external environment, and the channel in which the core of the solenoid moves is placed in the external environment. The release handle is made in the form of a lever mechanism and includes a curly folding lever interacting through a lever fork with a horizontal pusher, which has a bevel at the point of contact with the lever fork, which provides the lever effect when the pusher moves along the axis. In this case, the pusher is made with the possibility of movement when the core is pulled into the solenoid and the movement is limited by the emphasis of the lever mechanism.

The difference between the disconnector is also that one end of the curly folding lever is made in the form of a plate hook, and the second end of the lever is pivotally connected to the lever fork.

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.

Figure 1 shows the General circuit breaker for returned underwater vehicles; figure 2 presents a structural diagram of the lever mechanism of the circuit breaker, explaining its operation; figure 3 gives a concretization of the structure of the trigger mechanism of the circuit breaker.

The operation of the circuit breaker for returned underwater vehicles is as follows.

The base 1 of the disconnect housing is attached from above to the returned apparatus, and by the hook of the lever 3 to the ring 10, which is connected to the load holding the underwater apparatus at a given depth. In this case, the second end of the lever 3 through the fork 4 is locked with a pusher 5 and is limited by a stop 6.

By the hydroacoustic signal supplied from the carrier vessel, or by the command signal programmed by the timer control device, the contacts of the reed switch 14 of the trigger 2 are closed, and a pulse is supplied to the coils of the solenoid 11 (Fig. 3). The core 12 is drawn into the channel of the solenoid 11, and the pusher 5 by means of the spring 9 moves in along its axis, interacting through the fork 4 with the lever 3 (Fig.1, 2). The bevel 7 of the pusher 5 at the point of contact with the fork 4 provides a lever effect during the movement of the pusher 5, and the ratio of the shoulders of the lever will consist of two ratios: the ratio of the shoulders of the own lever 3 and the ratio determined by the angle of the bevel 7 of the pusher 5. Under the influence of the weight of the load, the pusher 5 moves releasing the fork 4 of the lever 3, the lever 3 leans back (rotates around the axis 8) and frees the ring 10 from the grip with the weight attached to it.

Communication with the control device of the circuit breaker (the control device is usually located in the body of the underwater vehicle [1-3] and is not shown in FIG.) For supplying power to the reed switch 14 and to the coils of the solenoid 11, as well as for transmitting command signals for opening through the pressure seal 16, which is equipped with a cover 15 of the casing 13 of the trigger 2.

Since the solenoid 11, the reed switch 14 and the casing 13 of the trigger 2 are placed in the compound fill 17, the trigger 2 is completely isolated from the external environment (except for the channel of the solenoid 11, in which its core 12 is moved). In this case, the lever mechanism of the circuit breaker does not have unreliable sealing elements.

Thus, from the description of the circuit breaker and its operation, it follows that its purpose is achieved with the specified technical result, which is in a causal relationship with a combination of essential features.
