A rapid extinguishing device for alcohol lamp rollover in chemical laboratory

Abstract

The invention relates to the technical field of laboratory fire suppression devices, and discloses a chemical laboratory alcohol lamp side-turning rapid extinguishing device. The device comprises a cylinder body, wherein the upper portion of a floating body is provided with circular grooves, the upper portion of a floating body is provided with second rotating columns, the lower portion of the floating body is provided with first hanging rings, the lower ends of the first hanging rings are connected with pull wires, the lower ends of the pull wires are connected with spray heads, the upper ends of the spray heads are fixedly connected with second hanging rings, and the lower ends of the spray heads are connected with the inner walls of conical grooves through springs. According to the device, the first hanging rings on the floating body are connected with the second hanging rings through the pull wires, the tension borne by the spray heads are changed, the pull wires on the left sprayheads is looser, the springs extrude the spray heads to move to the right around first rotating columns, in a similar way, the right spray heads move to the left, the structure achieves the spraying angle aggregation of the spray heads, and the problem that an existing chemical laboratory fire extinguisher does not have rapid fire extinguishing, and excessive chemical item toppling is easily caused is solved.

Description

technical field [0001] The invention relates to the technical field of laboratory fire extinguishing devices, in particular to a rapid rollover extinguishing device for alcohol lamps in chemical laboratories. Background technique [0002] Alcohol lamp is a heating tool fueled by alcohol, which is widely used in laboratories, factories, medical treatment, scientific research, etc. Since it does not produce smoke during combustion, it can also be sterilized by burning the device. Because of the heat generated during the burning process of the alcohol lamp, other experimental materials can be heated. Its heating temperature reaches above 400-1000 ℃, and it is safe and reliable. Alcohol lamps are divided into hanging alcohol blowtorch and sitting alcohol blowtorch as well as conventional alcohol lamps, laboratories, etc. are generally made of glass. [0003] When the seated alcohol lamp is used in the laboratory, it may fall over due to the collision of foreign objects. Since...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a quick extinguishing device for alcohol lamp rollover in a chemical laboratory, which has the advantages of rapid fire extinguishing, avoiding the dumping of excessive chemicals, and ensuring the safety of firefighters, and solves the problem of existing chemical experiments. The indoor fire extinguisher does not have the ability to quickly extinguish the fire, which will easily lead to the dumping of too many chemicals, which may cause safety problems for firefighters
