Description

Technical Field

[0001] The utility model relates to a detection device, in particular to a fire extinguisher efficiency detection device, belonging to the technical field of fire extinguishing efficiency detection. Background Art

[0002] Firefighting equipment is used for firefighting, fire prevention and fire accidents. Fire extinguishers are common firefighting equipment. The inspection of the firefighting efficiency of fire extinguishers is the core technical indicator for measuring product quality. Therefore, after the production of fire extinguishers, it is necessary to use a detection system to test their firefighting efficiency.

[0003] At present, fire extinguisher manufacturers and testing institutions mainly use manual testing to test the fire extinguishing performance of fire extinguishers. During the test, two-thirds of water is spread on a specified iron disc, and then a layer of fuel is spread, and then the fuel is ignited. The tester wears protective clothing and holds the tested fire extinguisher to extinguish the fire. Within the specified time, the dry powder in the fire extinguisher is sprayed out. If all the sparks in the iron disc are sprayed out, the fire extinguisher can be judged to be qualified, otherwise the fire extinguisher is unqualified. However, when the tester holds the fire extinguisher to extinguish the fire, the interference of human control factors is relatively large. Factors such as the tester's experience, the distance from the fire, and the way of holding the fire extinguisher cannot be the same every time, making the test accidental. In order to reduce the accidental nature, multiple experiments are required, but the control conditions of each experiment are greatly interfered by human factors. Therefore, the accuracy of the fire extinguishing performance test is low. For this reason, a fire extinguisher efficiency detection device is proposed. Utility Model Content
