In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. The terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.

As shown in fig. 1, the sonobuoy comprises a parachute assembly, a water surface electronic cabin 4, a depth setting component, an underwater extension and a buoy bottom cover 8 which are sequentially connected from top to bottom, wherein the buoy bottom cover 8 supports the underwater extension, the depth setting component and the underwater extension are placed in a body setting outer shell 6, and the parachute assembly comprises a hanging plate 2. The structure of the existing product is not repeated.

The scheme aims to solve two problems, namely, the weight and the cost of the whole buoy are reduced, and the use of the traditional outer cylinder is avoided; secondly, solve the surface of water electronic cabin 4, fixed deep part, use the screw fixation mode to cause the condition that dead mark appears easily between the extension under water, for example, vibration or rock, the screw looseness, the joint is on with the urceolus inner wall, causes each part unable to break away from in the urceolus.

The scheme for avoiding the use of the traditional transmitting cylinder or the outer cylinder is as follows:

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 landing assembly acts, the hanging plate 2 is pulled upwards, the hanging plate 2 is driven to bend and deform and is separated from contact with the top end of the retainer 18, and after the retainer 18 is separated from contact with the hanging plate 2, the bottom end of the retainer is driven to be separated from contact with the buoy bottom cover 8, so that the water surface electronic cabin 4, the depth fixing part and the underwater extension are separated.

Specifically, the holder 18 is detachably connected to the hanging plate 2 and the buoy bottom cover 8. For example, the parachute landing assembly comprises a parachute support 1, and a parachute is installed in the parachute support 1. The hanging plate 2 is provided with lugs 3 along the radial direction, and the lugs 3 extend out of the parachute support 1 to be connected with the corresponding positions of the top ends of the retainers 18 in a nested mode, namely, the lugs 3 penetrate through holes of the retainers 18.

As shown in fig. 2 or 3, the structure of the retainer 18 is arranged in a straight line structure or in an arc structure, for example, the retainer 18 is arranged in an L-shaped structure including a vertical plate and a horizontal plate, the vertical plate is arranged in an arc structure or in a U-shaped structure with a U-shaped opening facing upward, wherein:

when the retainer 18 is arranged in an L-shaped structure, the waist-shaped holes or grooves 20 are symmetrically arranged at 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 ends of the bosses are connected with the buoy bottom cover 8 in a nested manner.

In the above manner, the retainer 18 replaces the traditional transmitting cylinder or outer cylinder, 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 water or buoy is transmitted, the parachute is opened and drives the hanging plate 2 to deform, so that the lugs 3 are separated from contact from the retainer 18, and all the components are not limited by the retainer 18 and are respectively unfolded. The use of the sheet metal machined cage 18 replaces the traditional long cylindrical outer housing, reducing the weight, cost and assembly difficulty of the sonobuoy.

Jie Juesi, as follows:

as shown in fig. 4, the water surface electronic cabin 4, the depth fixing part and the buoy bottom cover 8 are connected in a nested manner from top to bottom. Be provided with adapter ring 5, adapter ring 5 installs between surface of water electronic cabin 4 and depth setting part, and the adapter ring 5 is close to and is set up first interior slot on the inner circumference of upper edge, as shown in fig. 5, (first interior slot annular closed groove structure sets up) surface of water electronic cabin 4 bottom outer circumference is last to set up with the first outer slot 11 with first interior slot shape adaptation, first interior slot and first outer slot 11 are formed with first installation cavity 14, place the circular line 9 that high elasticity and high hardness material were made in the first installation cavity 14, for example, spring wire, wherein:

the round wire 9 is filled in the installation cavity, replaces the connection mode of using screws for the water surface electronic cabin 4 and the adapter ring 5, and avoids the situation that the conventional mode uses the transmitting cylinder to easily cause loosening of the screws and limit the movement of the buoy in the transmitting cylinder. The installation environment of the buoy is usually subjected to vibration and impact conditions, so that the screw loosens.

Further, as shown in fig. 6, a second inner groove 12 is disposed on an inner circumferential surface of the adapter ring 5 adjacent to a lower edge, a second outer groove 13 adapted to the shape of the second inner groove 12 is disposed on an outer circumferential surface of the depth fixing member adjacent to a 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 installation cavity 15, replaces the connection mode of the fixed-depth component and the adapter ring 5 by using screws, and is easy to appear because the screws loosen to limit the movement of the buoy in the launching tube.

In the above-mentioned scheme, as shown in fig. 7, the round wire 9 is convenient to be placed, and the first opening 16 and the second opening 17 are symmetrically or staggeredly arranged on the circumferential surface of the adapter ring 5, and the first opening 16 and the second opening 17 are respectively communicated with the first installation cavity 14 and the second installation cavity 15 for installation of the round wire 9.

The use of a shell-less/screwless buoy pod connection scheme eliminates the risk of screw loosening leading to jamming of the sonobuoy to become a dead standard.

The buoy is put into water, then an air charging device in the water surface electronic cabin 4 is activated, an air bag communicated with the air inside the water surface electronic cabin 4 is inflated, the volume is increased after the air bag is inflated to enable the parachute hanging plate 2 to deform upwards, the protrusions on the circumference of the parachute hanging plate 2 are separated from waist-shaped holes on the upper portion of the retainer 18, the air bag continues to expand to enable the parachute landing part to be separated from the water surface electronic cabin 4 and then float to the water surface to communicate with the outside under the action of buoyancy, meanwhile the retainer 18 is overturned to the side under the action of self gravity so as to be separated from the bottom cover 8, and the parachute landing part is sunk to the working depth under the action of gravity of the bottom cover 8.

The product provided by the invention is described in detail above. The principles and embodiments of the present invention have been described herein with reference to specific examples, the description of which is intended only to facilitate an understanding of the core concepts of the invention. It should be noted that it will be apparent to those skilled in the art that several improvements and modifications can be made to the invention without departing from the inventive concept, and these improvements and modifications fall within the scope of the appended claims.
