According to the sonobuoy shown in the figure 1, an umbrella drop assembly, a water surface electronic cabin 4, a depth fixing component, an underwater extension set and a buoy bottom cover 8 are sequentially connected from top to bottom, the buoy bottom cover 8 supports the underwater extension set, the depth fixing component and the underwater extension set are placed in a body fixing outer shell 6, and the umbrella drop assembly comprises a hanging plate 2. The structure of the existing product is not described in detail.

The scheme aims at solving two problems, namely, the weight and the cost of the integral buoy are reduced, and the use of the traditional outer cylinder is avoided; secondly, the problem that dead marks are easily caused to appear between the water surface electronic cabin 4, the depth fixing component and the underwater extension in a screw fixing mode is solved, for example, vibration or shaking is caused, screws are loosened, and the parts are clamped on the inner wall of the outer barrel, so that the parts cannot be separated from the inner barrel.

The scheme for avoiding the use of the traditional launching tube or outer tube comprises the following steps:

the hanging plate 2 can be bent under the action of external force and is made of sheet metal materials. Still include holder 18, the nested link plate 2 in holder 18 top, the nested buoy bottom cover 8 in bottom, wherein: when the parachute assembly acts, the hanging plate 2 is upwards stretched, the hanging plate 2 is driven to bend and deform and is separated from the top end of the retainer 18, and after the retainer 18 is separated from the hanging plate 2, the bottom end of the retainer is driven to be separated from the buoy bottom cover 8, so that the water surface electronic cabin 4, the depth fixing part and the underwater extension set are separated.

Specifically, the retainer 18 is detachably connected to the peg board 2 and the float bottom cover 8. For example, the parachute assembly comprises a parachute bracket 1, and a parachute is arranged in the parachute bracket 1. The hanging plate 2 is provided with a lug 3 along the radial direction, and the lug 3 extends out of the parachute bracket 1 and is connected with the top end of the retainer 18 in a nested manner, namely, the lug 3 penetrates through the hole of the retainer 18.

As shown in fig. 2 or fig. 3, the structure of the holder 18 is arranged in a straight line structure, or in an arc structure, for example, the holder 18 is arranged in an L-shaped structure, the L-shaped structure comprises a vertical plate and a horizontal plate, the vertical plate is arranged in an arc structure, or in a U-shaped structure, and the opening of the U-shaped structure faces upwards, wherein:

when the retainer 18 is arranged in an L-shaped structure, the retainer is symmetrically arranged, waist-shaped holes or grooves 20 are formed in the bottom end of the retainer 18, bosses are arranged on the buoy bottom cover 8 corresponding to the waist-shaped holes or grooves and can be embedded into the waist-shaped holes or grooves, or when the retainer 18 is arranged in a U-shaped structure, the number of the bosses is one, and the bottom end of the retainer is connected with the buoy bottom cover 8 in a nested manner.

In the mode, the retainer 18 replaces the traditional launching tube or outer tube, the parachute assembly, the water surface electronic cabin 4, the depth fixing component, the underwater extension and the buoy bottom cover 8 are initially fixed through the retainer 18, after the parachute enters water or the buoy is launched, the parachute is opened and drives the hanging plate 2 to deform, so that the lugs 3 are separated from the retainer 18, and all the components are not limited by the retainer 18 and are respectively unfolded. The retainer 18 processed by sheet metal is used for replacing the traditional long cylindrical outer shell, so that the weight, the cost and the assembly difficulty of the sonobuoy are reduced.

The technical scheme for solving the death mark is as follows:

as shown in fig. 4, the surface electronics bay 4, the depth setting member and the buoy bottom cover 8 are connected in a nested manner from top to bottom and in front of each other. The water surface electronic cabin is provided with an adapter ring 5, the adapter ring 5 is installed between the water surface electronic cabin 4 and a depth-fixing component, and a first inner groove is arranged on the inner circumferential surface of the upper edge of the adapter ring 5, as shown in fig. 5, (the first inner groove is arranged in an annular closed groove structure), a first outer groove 11 matched with the first inner groove in shape is arranged on the outer circumferential surface of the bottom of the water surface electronic cabin 4, a first installation cavity 14 is formed by the first inner groove and the first outer groove 11, and a round wire 9 made of a high-elasticity and high-hardness material, such as a spring steel wire, is placed in the first installation cavity 14, wherein:

round wire 9 is filled in the installation cavity, replaces surface of

water electron cabin

4 and 5 connected modes that use the screw of adapter ring, avoids traditional mode to use the launch canister easily to appear because of the screw is not hard up, and the restriction buoy appears in the condition of the removal of launch canister. The mounting environment of the buoy is often subject to vibration and shock conditions that can cause the screws to loosen.

Further, as shown in fig. 6, a second inner groove 12 is disposed on the inner circumferential surface of the adapter ring 5 adjacent to the lower edge, a second outer groove 13 adapted to the shape of the second inner groove 12 is disposed on the outer circumferential surface of the depth-fixing member adjacent to the top surface, a second installation cavity 15 is formed by the second inner groove 12 and the second outer groove 13, and a round wire 9 is disposed in the second installation cavity 15, wherein:

the round wire 9 is filled in the second mounting cavity 15, the depth fixing component and the adapter ring 5 are replaced to be mounted in a screw connection mode, and the situation that the movement of the buoy in the launching tube is limited due to the loosening of screws is prone to occurring.

In the above solution, as shown in fig. 7, the round wire 9 is conveniently placed, the first notch 16 and the second notch 17 are symmetrically or staggeredly arranged on the circumferential surface of the adapter ring 5, and the first notch 16 and the second notch 17 are respectively communicated with the first mounting cavity 14 and the second mounting cavity 15 for mounting the round wire 9.

The adoption of the scheme of connecting the shell-free buoy cabin section and the screw-free buoy cabin section eliminates the risk that the sonar buoy becomes a dead buoy due to the clamping of the shell caused by the loosening of the screw.

After the buoy is thrown into water, an inflating device in the water surface electronic cabin 4 is activated to inflate an air bag communicated with gas in the water surface electronic cabin 4, the parachute hanging plate 2 is upwards pushed and deformed by the increase of volume after the air bag is inflated, the circumferential bulge of the parachute hanging plate 2 is separated from a waist-shaped hole in the upper portion of the retainer 18, the air bag is continuously expanded to separate the parachute component from the water surface electronic cabin 4, then the water surface electronic cabin 4 is driven to float upwards to the water surface under the action of buoyancy force to be communicated with the outside, meanwhile, the retainer 18 is overturned towards the side edge under the action of self gravity to be separated from the bottom cover 8, and the underwater extension is driven to sink to the working depth under the action of gravity of the bottom cover 8.

The products provided by the present invention are described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the core concepts of the present invention. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the invention without departing from the inventive concept, and those improvements and modifications also fall within the scope of the claims of the invention.
