Underwater gas collection device

Abstract

The invention discloses an underwater gas collection device which belongs to the field of diving equipment. The underwater gas collection device consists of a gas storage tank (1), a water sucking tank (13), a water discharge tank (9), a piston component (11) as well as valves and pipelines for connecting the tanks, wherein an air sealed space above the water discharge tank (9) is communicated with a space at the upper part of the water sucking tank (13) through a pipeline with a one-way valve; the lower part of the water discharge tank (9) is communicated with seawater through a water discharge pipeline with another one-way valve; a liquid part tank body at the lower part of the water discharge tank (9) is communicated with a liquid part tank body at the lower part of the water sucking tank (13) through a pipeline with another one-way valve; the tank body at the upper part of the water discharge tank (9) is communicated with the gas storage tank (1) through a gas storage tank inlet pipeline with another one-way valve; a switch valve is arranged on a gas inlet pipeline close to the gas storage tank (1); a water inlet pipeline with a depressurizing valve (3) and an overflowing valve (2) is arranged below the water sucking tank (13). A piston in a crankshaft sliding block mechanism is driven by a motor to move so as to change the pressure intensity inside the tank body, and the purpose of extracting air in water is achieved.

Description

technical field [0001] The invention belongs to the field of diving equipment, and in particular relates to an underwater air collecting device which extracts and stores dissolved air in water as the air needed for breathing during diving. Background technique [0002] Diving is originally an activity that enters below the surface of the water with or without professional tools for underwater survey, salvage, repair and underwater engineering operations. In recent years, with the development of the economy, people's demand for spiritual life has increased sharply. Diving has gradually developed into a leisure sport with underwater activities as the main content, so as to achieve the purpose of physical exercise, leisure and entertainment, and is widely popular among the public. Love, so the demand for diving equipment is increasing. [0003] Existing diving activities provide divers' oxygen needs during diving through the way divers carry oxygen tanks. In this way, the gas ...

Problems solved by technology

[0003] Existing diving activities provide divers' oxygen needs during diving through the way divers carry oxygen tanks. In this way, the gas in the oxygen tanks has been controlled in a reasonable proportion, so it is safe, reliable and suitable for deep-sea diving. At the same time, it has the advantages of manufacturing Convenience, mature technology, etc., but the oxygen storage is limited during the diving process, so it is not suitable for long-term diving operations. The oxygen tank needs to be re-stored oxygen every time you dive, and the oxygen production and storage process is complicated and costly, which hinders diving.
