Buoy releasing and launching device

Abstract

The invention discloses a buoy releasing and launching device, and particularly relates to an unmanned aerial vehicle pod type buoy releasing and launching device. The device is characterized in that an electromagnetic valve is connected with a launching cylinder fixing base through an upper cover plate, an upper cover is mounted between a first unlocking piece and the upper cover plate, a second unlocking piece and the first unlocking piece are limited through a step, and a pre-pressing spring is installed between the first unlocking piece and the second unlocking piece. When a sonar buoy needs to be launched, gas in the high-pressure gas cylinder controls on-off of the open circuit through the electromagnetic valve, so that a buoy releasing barrel is rapidly filled with the high-pressure gas in the high-pressure gas cylinder, the pressure generated by the high-pressure gas pushes the buoy and an unlocking mechanism, and buoy releasing is achieved. According to the technical scheme, a releasing executing mechanism which is lighter and cleaner is provided, and the problem that an existing high-pressure gas buoy releasing structure is complex, large, heavy, high in failure rate, uncontrollable in speed and the like is solved.

Description

technical field [0001] The invention relates to a buoy launching device, in particular to an unmanned aircraft pod type buoy launching device. Background technique [0002] As sonar buoys are used more and more frequently, they are used more and more on various aircraft platforms, and the delivery methods are also different. There are mainly gravity delivery, explosive delivery and high-pressure gas delivery. Gravity release is to use the sonar buoy's own gravity to make the buoy fall freely away from the buoy carrier. The system generally includes a set of release tubes. There is an electronically controlled spring door at the bottom of each release tube, or it can be opened and closed manually when the electronic control system fails. The aircraft attitude and speed requirements are high, and the structural design is relatively complicated. Explosive delivery is to use the high-pressure gas energy generated after the explosive explosion to push the buoy out of the body. ...

AI Technical Summary

Problems solved by technology

However, the existing high-pressure gas buoys are mostly released by piston rods to push the buoys. The structure is complex, the maintenance cost is high, and the weight is heavy.

The purpose of the present invention is to provide a more portable pneumatic actuator to solve the problems of complex structure, large volume, heavy weight, high failure rate and uncontrollable speed of existing high-pressure gas buoys.
