AI Technical Summary

Technical Problem

The existing explosion-proof motors are susceptible to external impact forces in harsh environments. The existing impact-resistant measures are complex in structure and require external shock-resistant equipment.

Method used

An impact-resistant explosion-proof motor is designed, adopting a structure including an explosion-proof body, an impact-resistant mechanism and an impact-resistant repeating mechanism. The impact-resistant mechanism realizes impact absorption through the side impact-resistant arc plate, the upper impact-resistant arc plate and the buffer filling layer. The impact-resistant repeating mechanism realizes the angle change and reset of the structure through the telescopic rod and the return spring.

Benefits of technology

It realizes that without installing external impact-resistant devices, effectively offset external impact force, ensures stable operation of explosion-proof motors, and is simple and easy to install.
