Abstract
The invention relates to the field of fire extinguisher detecting, and particularly discloses a fire extinguisher impact test device. The fire extinguisher impact test device comprises a vertical plate. The vertical plate is provided with a rack capable of sliding up and down. The rack is meshed with a gear arranged at the output end of a stepping motor. An electromagnet is arranged at the lower end of the rack. A groove is formed in the lower end of the electromagnet and internally provided with a steel hammer. A laser distance measurement lamp is arranged at the bottom of the groove. A camera is arranged at the lower middle portion of the outer side of the electromagnet. The stepping motor, the laser distance measurement lamp and the camera are respectively connected with a PLC system. The electromagnet is provided with a remote control switch connected with the PLC system. The fire extinguisher impact test device aligns with an impact point through a mechanical device, alignment is accurate, accurate test data can be obtained, the structure is simple, usage is convenient, the number of man-made interference factors is reduced, and the detection automation degree and scientificity are improved.
