Calcium carbide lamp capable of preventing acetylene gas from overflowing during replacement of calcium carbide

Abstract

The discloses a calcium carbide lamp capable of preventing acetylene gas from overflowing during replacement of calcium carbide. The calcium carbide lamp comprises a calcium carbide lamp water tank shell (11) and a calcium carbide lamp reaction shell (17), firstly, when calcium carbide is replaced, the device can completely seal the contact face, making contact with air, of the upper side of a calcium carbide reaction space, and in the sealing process, an air leakage prevention film which is arranged before is tightened, meanwhile, the calcium carbide reaction space is subjected to heat sealing forming, a sealing bag capable of containing reacted calcium carbide is formed, at the moment, the calcium carbide reaction space is reversed, residual calcium carbide can be placed in the sealing bag, then the sealing bag is sealed, and meanwhile residual acetylene gas in the calcium carbide reaction space is sucked away by an air extractor for reaction, the acetylene leakage phenomenon in the replacement process can be prevented, calcium carbide can move in the space through the rotating paddle, the calcium carbide makes contact with water again to react, then acetylene gas is generated, and the endurance time of the device is prolonged.

Description

technical field [0001] The invention relates to the field of lighting equipment, in particular to a calcium carbide lamp which prevents acetylene gas from overflowing when replacing calcium carbide. Background technique [0002] In caving sports or cave investigations, it is best for cavers to use calcium carbide lamps for lighting, because when there is a lack of oxygen in the cave, the flame color of calcium carbide lamps will change significantly, and calcium carbide lamps can effectively prompt cavers to exit in time to prevent Entering an area with low oxygen content during caving can lead to breathing difficulties or even suffocation. However, when the calcium carbide is burned out to remove the residue, the remaining calcium carbide gas will escape. It is necessary to prevent other people's calcium carbide lamp flames from igniting the escaped gas. Danger occurs, so when one person replaces a new calcium carbide, other people have to withdraw a certain distance (more ...

Problems solved by technology

[0002] In caving sports or cave investigations, it is best for cavers to use calcium carbide lamps for lighting, because when there is a lack of oxygen in the cave, the flame color of calcium carbide lamps will change significantly, and calcium carbide lamps can effectively prompt cavers to exit in time to prevent Entering an area with low oxygen content during caving can lead to breathing difficulties or even suffocation. However, when the calcium carbide is burned out to remove the residue, the remaining calcium carbide gas will escape. It is necessary to prevent other people's calcium carbide lamp flames from igniting the escaped gas. Danger occurs, so when one person replaces a new calcium carbide, other people have to withdraw a certain distance (more than five meters), but because the space in the cave is extremely narrow, and the air circulation is not smooth, it is very difficult to replace due to the leakage of acetylene And it is dangerous, so it is necessary to install a calcium carbide lamp that prevents acetylene gas from overflowing when replacing calcium carbide to improve the above problems.
