Novel automatic testing device for spray performance of fire extinguisher

Abstract

The invention belongs to the technical field of fire-fighting equipment products and particularly relates to a novel automatic testing device for the spray performance of a fire extinguisher. The novel automatic testing device for the spray performance of the fire extinguisher comprises an electronic scale, a support and a computer PLC, wherein the electronic scale, the support and the computer PLC are fixed to the ground. The novel automatic testing device for the spray performance of the fire extinguisher is characterized in that a fixing plate is arranged on the electronic scale, the fixing plate is connected with an air compressor, a horizontal pneumatic clamp holder is installed on the fixing plate, the horizontal pneumatic clamp holder is connected with an air cylinder A, elastic mats are arranged on the inner sides of the horizontal pneumatic clamp holder, the elastic mats are in direct contact with the fire extinguisher, the pneumatic clamp holder is installed on the upper portion of the fire extinguisher, a supporting rod is arranged on one side on the fixing plate, a rubber tube spray nozzle, the horizontal pneumatic clamp holder and a photoelectric switch are installed at the top end of the supporting rod, and a measurement grid is arranged on the top of the support. The novel automatic testing device for the spray performance of the fire extinguisher is simple in structure and convenient to use, replaces manual operation, improves the accuracy and the reliability of detection data, and improves the detection efficiency.

Description

(1) Technical field [0001] The invention relates to a novel fire extinguisher spray performance automatic test device, which belongs to the technical field of fire-fighting equipment product detection. (2) Background technology [0002] At present, the spray performance test of the fire extinguisher is to place the nozzle of the fire extinguisher horizontally and 1 meter above the ground at the specified temperature, measure the spray distance while spraying, and then place a marker with a length measurement mark on the side of the spray direction. Indicate the horizontal distance. When the fire extinguisher sprays 50% of the fire extinguishing dose, read the horizontal distance from the farthest point of the jet stream to the nozzle of the fire extinguisher, which is the spray distance. Determination of injection delay time is the time from the opening of the control valve of the fire extinguisher to the start of spraying of the fire extinguishing agent nozzle, and the ...

Problems solved by technology

However, at this stage, these tests are all completed by manual observation and control. Not only is the labor intensity high, the working environment is harsh, and there are many human interference factors, but also there are problems with low detection efficiency and data reliability, which brings great inconvenience to the detection.
