Abstract

The invention discloses an underwater rescue device which comprises a barrel shell, a middle ring, a sleeve and a piston. The upper end of the barrel shell is an opening. The sleeve comprises an upper sleeve body and a lower sleeve body. The lower sleeve body is arranged at the bottom in the barrel shell. A through hole communicating with the outer portion of the bottom of the barrel shell is formed in the bottom of the lower sleeve body. A piston rod is arranged at the bottom of the piston. The middle ring is fixedly connected with the outer circumference of the upper sleeve body and the inner wall of the barrel shell. A closed inflation chamber is formed among the outer portion of the sleeve, the barrel shell and the middle ring. A gap is formed between the upper sleeve body and the lower sleeve body. Half turn of a recessed thread is arranged at the top of the piston, and half turn of a protruding thread is arranged on the inner wall of the upper sleeve body. An air bag fixedly connected with the upper sleeve body is arranged at the top of the upper sleeve body. The inflation chamber is filled with compressed air. When rescue is needed, the piston rod is twisted to pull the piston downwards into the lower sleeve body, the compressed air in the inflation chamber enters the sleeve through the gap and rapidly inflates the air bag, and great buoyancy is provided for the rescue device. The underwater rescue device is simple in structure and good in reliability and further has the function of a safety hammer.

Description

technical field [0001] This patent provides a structure of an underwater rescue device, through which a person who falls into the water can quickly save himself or provide rescue equipment for the rescuer, which belongs to the technical field of mechanical pneumatics, and specifically relates to an underwater rescue device. Background technique [0002] There are few existing underwater rescue devices, and there are no better products that can effectively rescue people who fall into the water. The few remaining rescue devices (such as CN201520951074.3) fail to take the sealing of the gas tank into consideration, and there is a risk of gas leakage, resulting in product failure. Simultaneously, the design of the airbag and carrying also lacks rationality (such as CN201521143590.X). Contents of the invention [0003] The object of the present invention is to provide a reliable underwater rescue device, which has reliable performance and can quickly save people. [0004]...
