Abstract

The utility model discloses a simple scuba, relating to a human being dive breathing apparatus, belonging to the class of underwater tool and equipment, comprising three parts, an air supply float, a respirator and an air transport hose. In the course of the operation, the gas supply float floats on the water surface, the air is transported from an umbrella-shaped air-in pipe via the air hose into the respirator. The respirator ensures the required breathing of the diving operation personnel depending on an air-in one-way valve and an air-out one-way valve. The utility model has the advantages of simple realization, low cost and convenient operation and portability, and is suitable for using during the fishing operation under the shallow water area.

Description

Simple SCUBA

The utility model relates to human Breathing device for utensil, belongs to the under-water operation equipment class.

People during operation, need to guarantee normal breathing condition under water.Under-water operation is many to carry the oxygen bottle oxygen supply, with bondsman's besoin de respirer for a long time.This oxygen supply equipment is heavier, and uses inconvenience, relatively is suitable for the deep diving activity.The purpose of this utility model is to provide a kind of simple possible, is suitable in the shallow water territory diving apparatus of fishing operation under water.It is simple and reliable for structure, and use is carried all very convenient.

The utility model is from the actual needs of shallow water territory fishing operation, and designed simple diving device comprises three parts, and one is the air feed float that swims on the water surface; The 2nd, the work drowned personnel are the respirator of mouthful rank under water; Third part is a bonded assembly air hose between air feed float and the respirator.

The air feed float of simple diving device is made float by rigid foam, and the umbrella shape air inlet pipe is installed in the position therebetween.Add base with well between umbrella shape air inlet pipe and float, the sleeve pipe of base is in order to passing the straight-tube portion of umbrella shape air inlet pipe, and can slide up and down along it, lays spring between the inside of umbrella shape air inlet pipe recess and base end face.When the umbrella shape air inlet pipe glides, spring is compressed, annular air scoop is with after the base end face contacts, annular air scoop is closed, thereby avoided because of annular intake pipe continues the possibility that sinking makes the water inlet of ring-type admission port, in normal operation, because the effect of spring, always make between ring-type admission port and base end face to keep certain clearance, air can enter the umbrella shape air inlet pipe from the ring-type admission port freely.

The respirator of simple diving device adopts three-port structure, and wherein, inlet end is installed into tracheae and breather check valve, and exhaust side is installed freeing pipe and exhaust check valve.They all add tightening seal washer between separately, and the 3rd end of threeway is then held in the mouth in work drowned personnel's mouth, as the passage with mouth breathing.

The respirator of simple diving device adopts breather check valve and exhaust check valve can make expiration independent separately with air-breathing path, has guaranteed normally carrying out of breathing.

The air hose one of simple diving device terminates to the straight tube end of umbrella shape air inlet pipe, and the other end is received on the air inlet pipe of respirator, and the junction, two ends will seal.

Description of drawings is as follows:

Figure one is work drowned figure.

Figure two is air feed Floater Structure figure.

Figure three is respiratory organ structure figure.

Wherein, 1-air feed float, 2-respirator, the 3-air hose, 4-float, 5-umbrella shape air inlet pipe, 6-ring-type admission port, 7-base, 8-spring, the 9-limiting gasket, 11-threeway, 12-air inlet pipe, the 13-freeing pipe, 14-left side seal ring, the right seal ring of 15-, the 16-breather check valve, the 17-exhaust check valve.

In the use, can select the air hose of sufficient length for use according to diving depth.When shallow water is fished for, as depth of water 2m, then select for use the long air hose of 2m enough, in the work drowned process, the moving of the bottom, also can spur air feed float shift position on the water surface by air hose with the work drowned personnel.
