Drowning prevention adjustable life buoy

Abstract

The invention discloses a drowning prevention adjustable life buoy. The structure of the drowning prevention adjustable life buoy comprises a gas exhaust seat, a life buoy body, a connecting clampingseat, a lifting handle, a liquid level guide wire, a liquid level meter, a gas exhaust joint, a gas exhaust type electric control valve, a power supply connecting wire and a PLC controller; the gas exhaust seat is embedded in one side of the life buoy body and is distributed symmetric to the connecting clamping seat; the connecting clamping seat is embedded in the other side of the life buoy body;and the lifting handle is welded on the external surface of the connecting clamping seat. According to the drowning prevention adjustable life buoy, through combination of the parts, the gas contentof the life buoy can be automatically adjusted according to the height of the current water surface during using, the use effect of the life buoy is effectively improved, the use is convenient, and the practicability is high.

Description

technical field [0001] The invention is an adjustable lifebuoy for preventing drowning, and belongs to the technical field of lifebuoys. Background technique [0002] The hollow rubber lifebuoy body is widely used in modern survival operations because of its strong gas storage capacity, high reliability, and many advantages of fitting the human body. [0003] However, the existing lifebuoy equipment cannot adjust the internal storage gas during the working process. In an emergency, it needs to use external manpower or equipment to inflate, which not only delays the time for help, but also due to the weight and weight of the person called for help in the process of asking for help. The difference in height makes it impossible to adjust the buoyancy, consumes too much physical strength of the rescuers, and is inconvenient to operate and poor in practicability. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the purpose of the present inventio...
