Description

The invention relates to the field of underwater shipbuilding, and in particular to devices for fastening and separating a pop-up emergency buoy with a connecting cable-cable, and is intended for use on underwater technical equipment (PTS) for storing and stowing buoys, for example, rescue boats for submarines.

A device is known “Inflated signal buoy", designed to launch an inflatable buoy from a submerged submarine or other PTS (England patent No. 1169273, IPC: B63B 21/52, published 05.11.69). This device contains a baffle in the case with a closing hatch, a mechanism for forcing buoys, including a cylinder with a piston, which is driven by a pyrotechnic charge (PTZ) located in the cylinder, a mechanism for dropping the manhole cover, and an alarm device. Undermining the PTZ is carried out by a signal from the control station.

Also known is a "Device for withdrawing a towed antenna from a robust hull of a submarine" (US patent No. 3245373, NKI: 114-235, IPC: B63G 8/38, B63B 21/00, declared June 25, 1964), providing the output of the buoy overboard.

This device contains a cylinder mounted in a durable case (PC) PTS with outer and inner airtight covers, inside which there is a buoy, while in the inner cover there is an opening with an oil seal for the passage of a flexible metal cable-cable connected with the buoy, and the outer cover opens by means of a hydraulic or mechanical drive of a known design, there is also a device for forcing buoy.

The disadvantage of this device is the low operational reliability due to the need to seal the outer and inner covers mounted in a sturdy hull of the submarine, as well as the presence of a drive to open the heavy outer cover. In case of unreliable sealing of these elements, outboard water can enter the hull of the submarine or jam the drive when the lid is opened.

It is also known "The device for mounting and separating an emergency submarine buoy" according to US patent No. 3933109, NKI: 114-16.5, which contains a hull (baffle), open at the top and inscribed in the upper part of the hull with locking devices equipped with grippers, and with a mechanism fastening-recoil of the buoy and chopping off the cable with two pyrotechnic cartridges (squibs). This baffle is located in the superstructure of the vessel, in its lower part there are 2 pyrotechnic cartridges (squib), which are controlled manually or automatically. When the squibs are triggered, the buoy with buoyancy is released. The buoy is equipped with additional buoyancy elements made in the form of cylinders of porous material. Locking devices hold the buoy by means of grippers interacting with the teeth mounted on the buoy. A pyrotechnic cartridge and cable connect the buoy to the submarine console.

This device does not provide reliable exit of the pop-up buoy from the chamber (baffle) when exposed to an oncoming hydrodynamic flow, pressing the buoy against the walls of the baffle, as well as with a significant emergency roll or PTS differential, since the buoy leaves the baffle only due to buoyancy. The delay in the exit of the buoy from the chamber can lead to its destruction in case of failure of the TCP of the maximum immersion depth.

This device is not reliable enough and durable in operation due to the fact that the elements of the locking device (springs, etc.) are in sea water and are subject to corrosion. The structure of spring steels is fine-grained, which leads to their more intense corrosion compared to case steels.

This device is unsafe in operation, since the buoy is unfastened by squibs, the powder gases of which cut the carrying part of the buoy body and cable. In the event of an unauthorized actuation of the squib during maintenance of the buoy, injuries to service personnel from the action of the shock wave of powder gases are possible.

It is also known "The device for mounting and separating a pop-up buoy on an underwater technical means" according to Russian patent No. 2214340, IPC 7: ВВВ 22/08, which contains a half-open housing inscribed in the upper part of the underwater technical means, a mechanism for forcing buoys, a locking device made in the form of rotary shields installed on top of the outside of the hull and having built-in buoyancy units from a lightweight durable aggregate, a fastening-recoil mechanism for the buoy and chopping off of the connecting cable (cut-off) with a pie technical drive.

The device according to the patent of Russia No. 2214340 is selected as the closest analogue.

In the known device, buoy buoys are insufficient, so a buoyancy unit from a lightweight durable aggregate is integrated only in shutter shields that cover the housing for their easy opening and does not provide the metal buoy with the necessary buoyancy when it emerges from depth to the sea surface together with an etched cable-cable, in addition, in the known device, the cable-cable connecting the buoy with the PTS is cut off simultaneously with the return of the buoy, which reduces the tactical capabilities of the rescued to the surface of the sea buoy due to the exclusion of the constant transmission of information from an emergency underwater technical means through a cable connected to the buoy.

In the known device, the buoy's mounting reliability is insufficient due to the fact that it is fixed in the lower part only to the support sleeve, while the locking devices do not hold the buoy tightly on the side surfaces. With this fastening, the oncoming hydrodynamic flow and the inertial forces arising from the movement of the PTS act on the buoy, swinging it relative to the lower support sleeve and the lower support ring.

In the known device there is no alarm about the return of the buoy, which reduces the operational characteristics of the emergency device.

The objective of the invention is to increase the tactical capabilities of the device, as well as its operational characteristics.

The problem is solved in that in the known device comprising a half-open housing with a bottom with an annular stop, a locking device and a buoyancy unit, a fastening-recoil mechanism of the buoy with a pyrotechnic drive, a movable piston and a rod mounted in a removable housing block on the bottom of the half-open housing is a cable cutter cable and the mechanism for forcing buoy, according to the invention, the half-open housing is made in the form of a truncated cone, facing a wide base up, the locking device is made in the form of a cover, mouth Mounted on the buoy, the buoyancy unit is fixed between the lid and the bottom around the buoy, and the cable cable is passed through the bottom of the hull and laid in the basket, while the basket is equipped with two interacting covers that are designed to rotate and release the cable, which are equipped with blocks buoyancy, and one of the lids is spring-loaded and configured to interact with the buoy by means of a pusher, which is passed through the bottom of the hull and is pivotally connected on one side to the buoy, and on the other to the basket lid.

In addition, on the lid, on the bottom and on the conical surface of the body, corresponding elastic gaskets are made to which the buoyancy unit is pressed, made of a lightweight durable aggregate, whose specific gravity is less than the specific gravity of water.

In addition, the buoy fastening-recoil mechanism is equipped with a rod displacement detector mounted on a movable piston to interact with an electric displacement transducer fixed in a removable housing unit with the possibility of adjusting its position.

In addition, the annular emphasis mounted on the bottom of the housing is made in the form of a clus with the possibility of passing through it a cable cable.

In addition, a hole for the passage of the pusher is made on the bottom of the housing, and a stop with a ball bearing surface is fixed on the buoy for swiveling with the pusher.

In addition, the pusher is configured to adjust its installation length.

In addition, the basket lid is spring-loaded by means of a lever mechanism mounted on the basket.

In addition, the cutter and the basket are installed near the place of attachment of the cable cable on the underwater technical equipment.

Integration into the device of a buoyancy unit, covering the buoy, fixed between the cover and the bottom of the buoy, made of lightweight durable aggregate with a lateral conical surface that abuts against the lateral conical surface of the recoil device, which increases the buoyancy, which makes it possible to float to the surface of the sea together with the etched cable from a deeply immersed emergency vehicle, as well as more securely fix the buoy in the hull during its storage due to for prison possible rocking of the buoy relative to the lower bearing sleeve and the lower annular abutment under the action of the hydrodynamic flow and counter-lateral inertial forces due to the motion of the TCP.

The introduction to the device of a basket for storing a cable cable with pivoting covers, with built-in buoyancy units made of lightweight strong aggregate, one of which is spring-loaded and pivotally connected via a pusher with an adjustable installation length with a stop with a ball bearing surface mounted on the buoy, allows reliable to store and at the same time secure the cable-cable to the PTS from etching, to ensure reliable opening of the basket lids, as well as an additional buoyancy force for the buoy to exit the body and to etch the a cable with a deeply submerged emergency TCP, and perform the stop ring, located in the lower housing part in the form of a cable fairlead for passing cable will ensure a reliable etching wire cable with a substantial heel and trim emergency TCP without additional its inflections.

Fastening on the movable piston of the fastening-recoil mechanism of the buoy of the rod movement detector with an electric converter fixed with the possibility of adjusting its position by a screw in a removable housing unit allows to improve the operational characteristics of the device by transmitting a signal to the TCP about the actual return of the emergency buoy.

The installation of a cutter with a pyrotechnic drive, chopping off the cable cable, behind the basket for storing the cable cable, in the area of fastening the end of the cable cable to the PTS, also allows to improve the operational characteristics of the device by ensuring the cutting of the cable cable when the emergency PTS is immersed to the maximum depth with the purpose of eliminating the flooding of a buoy that emerged with a cable-cable, and until that moment, the buoy’s connection with the TCP will be maintained, which improves its tactical capabilities.

The device for fastening and separating the pop-up buoy 1 with the cable-cable 2 on the PTS (see Fig. 1) has a housing 3 mounted flush with the superstructure 4 in the inter-side space of the PTS. The housing 3 has the shape of a hollow truncated cone, facing up with a wide base. A buoyancy unit 5 is built into the housing 3, made of a lightweight durable aggregate with a specific gravity lower than the specific gravity of the water, which covers the buoy 1 and is secured with ties 6 between the cover - a bolt 7, which protects the buoyancy unit 5 from the action of the ice load when the TCP emerges in the Northern latitudes, and the bottom 8 of the buoy 1 through the gasket 9. The buoyancy unit 5 abuts against the annular elastic gasket 10, mounted on the inner lateral upward tapering surface of the housing 3. The device also includes a fixed to housing 3, the mechanism 11 for pushing buoy 1, the support ring 12, rigidly mounted on the buoy 1, the ring stop 13, which is made in the form of a clus and is fixed in the lower part of the housing 3, the mechanism 14 of the fastening-recoil of the buoy 1 with an alarm, mounted in the housing 3, a stop 15 with a ball bearing surface and a support sleeve 16 with a side groove fixed on the bottom 8 of the buoy 1, a pusher 17 with an adjustable installation length, a basket 18 for laying and storing the cable 2 in it, equipped with rotary covers 19 and 20 ( cm. figure 1, 2).

The cover 20 is spring-loaded with a lever mechanism 21 and interacts with the cover 19 by means of a stop 22 (see Figs. 1, 2, 8). The pusher 17 is pivotally connected on one side with a stop 15 with a ball bearing surface, and on the other with a cover 20 of the basket 18. The covers 19 and 20 close the basket 18, in which the cable-cable 2 is laid, one end of which is fixed to the buoy 1, and another is attached to the TCP. In the lids 19 and 20, a buoyancy block 23 of a lightweight durable aggregate is built-in, providing ease of rotation and opening in the underwater position of the PTS. Near the basket 18 at the PTS, in the area of the cable-cable attachment 2, a cable-cable chopping mechanism is installed - a cut-off 24 with a pyrotechnic drive 25 (see Fig. 2, 9).

The housing 3 (see Fig. 1 and Fig. 2) is designed to store the buoy 1. The conical portion 26 of the housing 3 at the top ends with a rigidly mounted support flange 27, for which the housing 3 is flush with the superstructure 4 of the MTS. The conical portion 26 of the housing 3 at the bottom has a bottom 28 with a central hole. An annular stop 13 is mounted on the bottom 28, made in the form of a clus for the passage of the cable 2.

On the lateral outer surfaces of the housing 3 symmetrically relative to the buoy 1 mounted lever mechanisms 11 for pushing the buoy 1, which have pivoting levers 29 passing through the cutouts in the housing 3 and interacting through the rollers 30 with the bottom 8 of the buoy 1. (see Fig.1, 2 , 3).

On the bottom 28 of the housing 3, the hub 31 is rigidly fixed (see Figs. 1, 5), on which the fastening-recoil mechanism 14 of the buoy 1 with a trip signaling device is mounted. The bottom 28 also has a hole for the passage of the pusher 17.

The mechanism 11 of the forced ejection of the buoy 1 (see figure 1, 2, 3 and 7) is designed to eject the buoy 1 after it recovers from the internal cavity of the housing 3 of the device. The buoy 1 forced ejection mechanism 11 comprises: rotary tubes 32, which are located symmetrically with respect to the buoy 1, for example, on four sides of it. Each rotary tube 32 has two levers 29 rigidly fixed on it, hermetically closed on both sides by caps 33 having sealing rings 34. The caps 33 together with the pipe 32 are mounted on a stationary roller 35 with the possibility of rotation relative to the latter (see Fig. 7) . The roller 35 is located inside the pipe and is fixedly mounted in the support brackets 36 mounted on the housing 26. A power torsion spring (torsion) 37 is screwed onto the roller 35, one end of which is fixed to the stationary roller 35, and the other end to the rotary pipe 32 with levers 29, which rotates relative to the roller 35 when the buoy is pushed out 1. The internal sealed cavity of the pipe 32 is filled with anticorrosive grease to prevent corrosion of the spring 37 in the case of leakage of sea water into the inner cavity of the pipe 32.

The spring link mechanism 21 of the drive for opening the lid 20 of the basket 18 is similar in design to the mechanism 11 for pushing the buoy 1 out and differs in that instead of the rollers 30, a cover 20 is attached to the ends of the levers similar to the levers 29 (see Fig. 8).

The mechanism 14 of the fastening-recoil of buoy 1 with a trip signaling device (see Figs. 1, 2, 4, 5, 6,) is designed to secure the buoy 1 in the stowed position of the PTS, return the buoy 1 when it is released, and signaling the actuating drive of the recoil of the buoy 1.

The fastening-recoil mechanism 14 of the buoy 1 with the actuator of the pyrotechnic actuator includes an annular stop 13 mounted on the bottom 28, made in the form of a clus for the passage of the cable 2 with a hub 31 rigidly fixed on the bottom 28, a removable housing block 38 with guides installed in the grooves the hub 31, fixed by a pin 39 with a spring 40 (see Fig.6). In a removable housing unit 38, a piston 41 is installed, the axis of which is perpendicular to the axis of the hub 31, and a rod 42 is mounted in the middle of the piston 41 coaxially to the hub 31 with a head interacting with the shoulder of the support sleeve 16 of buoy 1, which is located in the hub 31 when buoy 1 is located in the case of 3 devices. In the hub 31, the sleeve 16 and the removable housing unit 38, a combined groove is made for longitudinal movement of the rod 42 in it. In the removable housing unit 38 on one side of the piston 41 there is a magnetic contactless detector 43 that interacts with the electric displacement transducer 44, which is fixed with the possibility of adjustment its position with a screw 45 on the housing unit 38 (see figure 4).

On the other side of the piston 41, a cylinder 46 is sealed with an integrated pyrotechnic charge 47 and a sealed cable entry 48. The cylinder 46 is mounted in a removable housing unit 38 coaxially with the piston 41 using an annular groove and a mortar cracker 49 installed in the corresponding groove made in the removable the housing unit 38. The embedded cracker 49 is rigidly fixed with a bolt 50. The cylinder 46 is sealed with rubber o-rings 51. The piston 41 is fixed relative to the removable housing unit 38 Yelnia pin 52.

The shut-off device 24 with a pyrotechnic drive 25 (see Figs. 8, 9) for chopping off the cable 2 is similar in design to the fastening-recoil mechanism of buoy 1 with an actuator for actuating the pyrotechnic drive and contains a piston 53, one side of which is hermetically mounted in cylinder 54 with an integrated a pyrotechnic charge (pyro cartridge) 55 and a sealed cable entry 56, and the other side of the piston 53 has a cutting edge that interacts with the cable-cable 2, when the cut-off device 24 is triggered. The cable-cable 2 is mounted in the groove of the removable cover 57 of the cut-off device 24 and closed prisoner of the TCP. To exclude spontaneous movement, the piston 53 is fixedly mounted in the cylinder 54 with a safety pin 58.

The operation of the attachment device - separation of the pop-up buoy 1 with the cable-cable 2 on the PTS occurs in two modes:

a) fastening the buoy 1 with a cable-cable 2 "in the marching" (initial);

b) in the mode of separation of the buoy 1 with a cable-cable 2 with PTS according to the return signal;

In the mounting mode "marching" (initial state), the elements of the claimed device are in the following position.

The buoy 1 is located inside the housing 3, the buoyancy unit 5, covering the buoy 1 and fixed between the cover 7, the bottom 8 and the lateral conical part 26 of the housing 3, expanding up, rests in the elastic gasket 10. The levers 29 are in the lower position and the rollers 30 are pressed to the bottom 8 of the buoy 1 by the force of the cocked power springs 37 of the torsion of the lever mechanism 11 of the forced ejection. The support ring 12 of the buoy 1 is pressed against the annular stop 13, the sleeve 16, rigidly mounted on the bottom 8 and having a side groove, is inserted into the hub 31, the rod head 42 is located inside the sleeve 16 and is engaged with its inner shoulder, holding the sleeve 16 from lifting together with buoy 1 (see figures 1, 2, 4, 6).

The cable-cable 2 passes through an annular stop 13 (see Figs. 1, 2), is attached at one end to buoy 1, and the other end is clamped by covers 19 and 20 with buoyancy units 23, laid in a basket 18, released from it, mounted in the cutter 24, located behind the basket 18, and mounted on the TCP.

The pusher 17, made with an adjustable installation length to ensure assembly of the device, at one end abuts against a stop 15 with a ball bearing surface, rigidly fixed to the bottom 8, and the other end is pivotally mounted on the cover 20, spring-loaded lever mechanism 21, and keeps it from opening.

In the fastening-recoil mechanism 14 of the buoy 1, the piston 41 with the rod 42 and the cylinder 46 are fixed in the housing block 38 with the help of an annular groove and a mortgage cracker 49 installed in the corresponding groove made in the removable housing unit 38. The mortgage cracker 49 is rigidly fixed with a bolt 50 ( see figure 4).

The piston 41 is fixedly mounted in the housing 38 by a safety pin 52, and the housing 38 with the guides is fixedly fixed in the hub 31 using a pin 39 held by the spring 40. The pyrotechnic charge 47 is placed inside the sealed cylinder 46 and connected to the electric cable entry cable 48. At the end of the piston 41, a signaling device 43 is fixed, for example a magnetic non-contact, interacting with an electric displacement transducer 44, fixed with the possibility of adjusting its position to adjust the magnetic contact of the screw m 45 on the housing unit 38.

When mounting the buoy 1 "in a marching" design, the device also provides for the possibility of servicing and removing the buoy 1 from the device without triggering a pyrotechnic charge 47. To do this, manually pressing the latch 39 compresses the spring 40 (see Fig.6,) and the housing unit 38 move along the guides of the hub 31 to the exit of the rod head 42 from the sleeve 16, as a result of which the buoy 1 can be pulled out of the housing 26, while under the action of the springs of the lever mechanism 21, the cover 20 opens and the cover 19 is manually opened to inspect the cable 2. Installation devices in the initial position is in the reverse order.

In the separation mode of the buoy 1 with cable 2, the inventive device, immersed in water, operates as follows.

On command from the control panel (not shown in the drawing), an electrical signal is supplied to the pyrotechnic charge 47 of the fastening-recoil mechanism 14 of buoy 1 (see Fig. 4), which is triggered and creates a significant excess gas pressure in the sealed cylinder 46, which acts on the piston 41 and moves it together with the rod 42 attached to it with the head, destroying the safety pin 52, and moves the detector 43, which through the electric converter 44 transmits a signal to the TCP to return the buoy 1. After moving the rod 42 with the head up to The ora into the hub 31, the sleeve 16 is released and exits the hub 31, while the floating buoy 1 begins to float up due to the buoyancy unit 5, as well as from the impact of the forced ejection mechanism 11 on it through levers 29 with rollers 30 pressed against the bottom 8 of the buoy 1 The levers 29 are rotated together with the pipes 32 due to the untwisting of the power springs 37 (see Fig.7). In addition, the pusher 17, by opening the spring-loaded cover 20 with the buoyancy unit 23, also forces buoy 1. When opening the cover 20, the cover 19 also opens, equipped with a buoyancy unit 23, which releases the cable 2, which is etched through the support ring (clus ) 13 from the basket 18 due to the positive buoyancy of buoy 1, floating to the surface of the sea for operation.

If the emergency vehicle is flooded to a depth greater than the limit and greater than the length of the cable 2, an electrical signal is sent to the pyrotechnic charge 55 (see Fig. 9), which is triggered by the signal of the outboard water pressure sensor (not shown). and creates a significant excess gas pressure in the sealed cylinder 54, which acts on the piston 53 and moves it, cutting off the safety pin 58 and cutting off the cable-cable 2 with the sharp edge of the piston 53, as a result of which the buoy 1 is separated from the PTS and works on the sea surface offline, keeping the latest information.

The cycle of operation of the claimed device ends.
