Sonar buoy

Abstract

The invention discloses a sonar buoy, belongs to the technical field of aeronautical sonar buoy application, and solves the technical problem that the service performance of a buoy is reduced due to the fact that the weight of the buoy in the prior art is large. A parachute landing assembly, a water surface electronic cabin, a depth keeping component, an underwater extension and a buoy bottom cover are sequentially connected from top to bottom, the buoy bottom cover supports the underwater extension, the parachute landing assembly comprises a hanging plate, the sonar buoy is characterized in that the hanging plate can be bent under the action of external force, the sonar buoy further comprises a holder, the top end of the holder is nested with the hanging plate, the bottom end of the holder is nested with the buoy bottom cover, wherein when the parachute landing assembly acts, the hanging plate is driven to bend and deform and break away from the top end of the holder, and after the holder breaks away from the hanging plate, the bottom end of the holder is driven to break away from the buoy bottom cover under the action of gravity, so that the water surface electronic cabin, the depth keeping component and the underwater extension set are separated. The weight and the cost of the buoy are reduced, the assembling difficulty of the buoy is reduced, and the reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of application of aviation sonar buoys, in particular to a sonar buoy. Background technique [0002] Sonobuoy is a kind of marine submarine exploration equipment, which is used to collect underwater target information. The prior art sonobuoy is mainly composed of a parachute component, a water surface electronic cabin, a depth-fixing component, an underwater extension unit and a buoy outer shell. In the prior art, the sonobuoys usually use screws to assemble the components, and then use the cylindrical long cylindrical shell to encapsulate the components of the sonobuoy, which increases the cost and weight of the buoy. The flotation airbag is not easy to maintain the folded state, which makes assembly difficult. At the same time, there is a risk that the screws are loose and stuck in the outer shell, so that the relevant parts cannot be released from the outer shell after the buoy is put into the water, so ...

Problems solved by technology

In the prior art, the sonobuoys usually use screws to assemble the components, and then use the cylindrical long cylindrical shell to encapsulate the components of the sonobuoy, which increases the cost and weight of the buoy. The flotation airbag is not easy to maintain the folded state, which makes assembly difficult. At the same time, there is a risk that the screws are loose and stuck in the outer shell, so that the related parts cannot come out of the outer shell after the buoy is put into the water, so that the sonobuoy becomes a dead mark.
