Abstract

The invention discloses an automatic fire extinguisher injection electric insulation performance testing device, which belongs to the field of product detection. The device comprises a pneumatic clamping and releasing mechanism, an electric insulation testing mechanism, an automatic fire extinguisher positioning mechanism and a PLC, wherein the automatic fire extinguisher positioning mechanism is used for adjusting a position of the fire extinguisher so as to ensure an injection thing of the fire extinguisher to be between a conductive pin and a metal plate; the pneumatic clamping and releasing mechanism is used for clamping or releasing an injection nozzle of the fire extinguisher so as to ensure the injection nozzle to be fixed during the testing process and improve the testing accuracy; the electric insulation testing mechanism is used for forming the test; and the PLC is used for controlling the pneumatic clamping and releasing mechanism, the electric insulation testing mechanism and the automatic fire extinguisher positioning mechanism to complete automatic control. Labor environment is improved, human disturbance factors are reduced, automatic detection is realized, and detection quality and efficiency are improved obviously.

Description

technical field [0001] The invention relates to the technical field of product detection, in particular to an automatic test device for the spray electrical insulation performance of a fire extinguisher. Background technique [0002] National standards have certain requirements for the electrical insulation performance of fire extinguishers. When using portable fire extinguishers to extinguish live equipment fires, it is required that the leakage conductivity of the jets ejected from the fire extinguisher be lower than a certain value to ensure that firefighters will not be shocked by electric shocks. harm. [0003] However, in the prior art, the electrical insulation test of fire extinguishers mostly adopts a semi-manual operation method. Due to the harsh working environment and many human interference factors, the quality and efficiency of the test are affected. Contents of the invention [0004] In order to solve the problems of low efficiency and large error in testin...
