AI Technical Summary

Technical Problem

In the high-voltage switch cabinet, when the handcart is pushed out, the handcart cannot stop moving immediately because the staff cannot detect the resistance in the cabinet in time, which may cause further damage.

Method used

A high voltage switch cabinet including a handcart assembly, a propulsion assembly and a protective mechanism is designed. The propulsion assembly is matched by the screw and the moving block. When the handcar encounters resistance, the moving block moves relative to the handcar, and drives the protective mechanism to lock the screw to prevent the handcar from continuing to move.

Benefits of technology

It effectively avoids damage caused by continuing to move when encountering resistance. At the same time, the bumper assembly prevents the car from suddenly stopping, reducing the risk to the operator.

Abstract

The present invention relates to the technical field of switch cabinets, and specifically discloses a high-voltage switch cabinet, comprising a cabinet body, a cabinet door being hingedly connected to the front end of the cabinet body, a static contact being arranged in the cabinet body, and a trolley assembly, a propulsion assembly and a protection mechanism arranged in the cabinet body, the trolley assembly comprising a trolley, a contact arm and a moving contact, the propulsion assembly comprising a screw rotatably arranged in the cabinet body, and a moving block cooperating with the screw thread, the protection mechanism comprising a locking assembly and a buffer assembly, the locking assembly comprising a ratchet structure and a driving structure, the driving structure being used to drive the ratchet structure to perform unidirectional locking on the screw when the moving block moves relative to the trolley, and the buffer assembly comprising a rotating part and a buffer structure arranged at the end of the screw; the present invention can lock the propulsion assembly when the movement of the trolley encounters resistance, so as to prevent the trolley from continuing to move and causing further damage, and at the same time can prevent the trolley from suddenly stopping and causing harm to the operator.
