The air-filled life belt is composed of a manual control gas generator, an air belt, an auto-controlled gas generator, an inflation pipe, etc. chemical reaction is carried out between water and gaseous chemical compounds generated when contact with the water by via the manual control gas generator or the auto-controlled gas generator, and gases are generated; thereby, the air belt is inflated and is blew up and pull people out of water. The utility model with the advantages of simple structure, low cost and convenient carrying is an ideal life preserver for swimmers and personnel working on the water.

Description

Inflatable life-saving belt

The utility model relates to a lifesaving device for swimming or overwater operating personnel. The existing life-saving equipment such as life jackets and life rings are generally in a solid state or are pre-inflated before entering water, so that the volume is large, and inconvenience is brought to normal swimming or operation. Chinese patent ZL93200081.9 discloses a manual and automatic combined inflatable life-saving device, which is mainly characterized in that the valve has two sets of control mechanisms, but has the following disadvantages: the support material can be softened and dissolved in water for a period of time to act, and the dissolved matter pollutes water; the life-saving device belongs to mechanical transmission, can be repeatedly used in water, and parts can not rust, thus being easy to cause failure.

The utility model aims at providing a convenient to carry, control is simple, safe and reliable's inflatable life saving equipment.

The purpose of the utility model is realized like this: the inflatable life-saving device consists of a manual control gas generator 7, a gas belt 10 and the like. In addition, the automatic control gas generator 26 and the inflation conduit 17 have two functions of manual control and automatic control.

The manual control gas generator 7 is provided with a water bag switch 1 with a water bag head 3 and water 14, a water bag switch plug 2 and a water bag switch plug hole 13 which can be inserted by the water bag head 3, an exhaust hole plug 5 and an exhaust plug hole 6, inflation holes 9 arranged on the end faces of two ends, grooves 8 arranged outside the two ends, and a compound 12 which can generate gas when meeting water; small rubber rings 11 are sleeved outside two ends of the gas belt 10, and two ends of the gas belt 10 are fixedly fastened on corresponding positions of grooves 8 at two ends of the manual control gas generator 7 through the small rubber rings 11; one side of the self-control gas generator 26 is provided with a plug hole 18 and a plug 19 which can be penetrated by the inflation conduit 17 in the middle, the upper part is provided with a spherical cavity consisting of an opening 21 and a valve 22, and an opening 23 and a valve 25, a compound which can generate gas when meeting water is filled in an air chamber at the lower part, and the other side is provided with a large rubber ring 24 which can be worn on the head; the tracheal end 15 of the inflation tube 17, with water 14 at one end, passes through a plug 16 that can be mated with the vent 6.

The manual lifesaving working process realized by the inflatable lifesaving belt is as follows: a proper amount of compound 12 capable of generating gas when meeting water, such as calcium carbide (CaC), is added into a manual gas generator 7 through an exhaust hole 6₂) Then, the vent hole plug 5 is used for plugging the vent hole plug 6, and the water bag head 3 of the water bag switch 1 which stores water 14 passes through the water bag switch plug 2 to plug the water bag switch plug hole 13 together, and the two are fastened through the small rubber ring 11. The inflatable belt 10 is then worn over the waist or under the armpits of the user. The mouth of the water bag switch 1 is closed under the normal state, when a user needs to use the air belt 10 for life saving, the user immediately pinches and presses the water bag switch 1 by hand to enable the water in the water bag switch 1 to be injected into the cavity of the manual gas generator 7, and then the compound 12 which generates gas when meeting water reacts with the water to generate gas. Such as calcium carbide (CaC)₂) The chemical reaction formula generated when meeting water is as follows:

the gas (e.g. C)₂H₂) Enters the gas belt 10 through the gas filling hole 9, and the gas belt 10 acts on gasThe expansion is expanded under the action, so that the upper body of a user is supported out of the water surface, and the aim of lifesaving is fulfilled. After the gas band 10 is used, the vent plug 5 can be pulled out, the gas is released, and the gas band 10 elastically contracts and is reduced into a band shape.

The working process of realizing self-control lifesaving by the inflatable life belt is the same; the plug 16 arranged on the inflation conduit 17 carried by the self-control gas generator 26 and the inflation conduit head 15 are plugged into the exhaust hole 6, and the self-control gas generator 26 is worn on the head of the user through the large rubber ring 24, and the gas belt 10 is sleeved on the waist or the armpit of the user. When the head of the user is sunk into water, the water automatically touches the

valves

22 and 25 in turn, enters the air chamber at the lower part of the self-control gas generator, and generates gas by chemical reaction with the compound 12 which generates gas when meeting water. The gas reversely closes the

valves

25 and 22 on one hand and enters the gas conduit 17 on the other hand, the water 14 in the hair 15 of the gas conduit is extruded to enter the manual control gas generator 7, the gas conduit head 15 is automatically closed after the water in the gas conduit head is extruded, the extruded water 14 reacts with the compound 12 to generate gas, the gas enters the gas belt 10 to expand and swell the gas belt 10, so that the upper body of the human body sinking into the water is lifted out of the water surface, and the aim of lifesaving is achieved.

The utility model has the advantages that: because the manual control or automatic control generator has small volume and the air belt is in a belt shape, the generator can not bring inconvenience to users when being tied to the waist or the armpit when the lifesaving is not carried out. Because the gas in the gas band is generated by chemical reaction, the gas is quickly obtained, and the life saving is timely, so the use is very convenient, safe and reliable. The utility model has simple structure, wide material acquisition and low cost, and is an ideal lifesaving tool for swimmers or water operators.
