Problems solved by technology

[0002] At present, after the existing aviation, land transportation or vehicles fall into the water without or lose their power source, their electric or pneumatic transmission components also lose their function one after another, and various pneumatic and safety control components are also out of control or unable to work; Some electro-pneumatic or electro-hydraulic transmission devices cannot meet the needs after falling into the water. The power supply of the transmission mechanism fails in the water, resulting in the paralysis of the electrical control system affecting the transmission capacity of its mechanical components and losing its function one after another, which makes the equipment and personal safety after falling into the water loss of protection

Abstract

The invention provides an air pressure power device for underwater spontaneous starting and a spontaneous starting method. The air pressure power device comprises a cylinder, an active cover plate, a passive cover plate, a piston rod, a piston, a one-way valve, a charging hole and a screwed plug or a valve. The active cover plate is fixed to one end of the cylinder, and the passive cover plate is fixed to the other end of the cylinder. The one-way valve is arranged on the active cover plate. The piston is arranged in the cylinder. The piston rod stretches into the cylinder from one end of the passive cover plate, and the end, stretching into the cylinder, of the piston rod is fixedly connected with the piston through a nut. A power air source is formed among the piston, the one-way valve and the cylinder. The charging hole is formed in the position, on the side wall of the power air source, of the cylinder and sealed by the screwed plug or the valve. The air pressure power device can meet the power needs of various pneumatic valves and safety control components without any external power source, escape time can be bought, the personal safety coefficient can be improved, and economic losses are lowered or reduced. The air pressure power device is simple in structure and convenient to grasp, use and maintain.
