Mechanical triggering method based on differential pressure driving

Abstract

The invention discloses a mechanical triggering method based on differential pressure driving. The method comprises the following steps that a movable block is arranged inside a cavity communicating with an external environment, and the cross sections of the two ends of the movable block are different, pressure difference borne by the movable block also changes along with the change of the pressure intensity of the external environment; a resistance which is opposite to the pressure difference is applied to the movable block, at the initial time, the movable block is stressed to be balanced, so that the movable block do not move in a static mode, the pressure difference is gradually changed along with the pressure intensity of the external environment, when the pressure difference reachesa set critical point, the stress balance of the movable block is broken, so that the movable block moves in a certain direction; and when the movable block moves, the movable block further pushes a trigger mechanism, so that the trigger mechanism can generate certain mechanical actions, and therefore designated work is completed. The mechanical triggering method based on the differential pressuredriving has the beneficial effects that the triggering method is mechanical and any sensor and electronic equipment are not be used, so that a series of problems caused by triggering of an electronicmode can be effectively solved, and work is very reliable and stable.

Description

technical field [0001] The present invention relates to a triggering method for action processes such as load dumping, in particular to a mechanical triggering method based on differential pressure drive. Background technique [0002] At present, with the acceleration of technological progress, more and more devices will use trigger methods when performing certain actions. For example, underwater vehicles or profile instruments need to release objects at a set water depth, and airships or space shuttles need to automatically dump exhaust fuel tanks at a certain height in the sky. The above-mentioned action process needs to be triggered before execution. method to trigger. At present, electronic methods are mostly used to trigger the above actions, which have relatively strict requirements on the external environment, and have problems such as complex circuit structure, high cost, and poor stability. Contents of the invention [0003] Based on the above technical problems...
