[0009] In a preferred scheme, the lower surface of the clamping plate is provided with a guide sliding block, and the inner bottom wall of the mounting slot is provided with a guide sliding groove for the sliding of the guide sliding block.

[0010] By arranging the guide sliding block, the clamping plate can smoothly move in the mounting slot under the sliding assistance of the guide sliding block.

[0011] In a preferred scheme, the opposite faces of the two clamping plates are embedded with first temperature-conducting copper plates, and the side of the clamping plates away from the first temperature-conducting copper plates is embedded with a semiconductor refrigerator, and the refrigeration end of the semiconductor refrigerator is overlapped with the first temperature-conducting copper plates.

[0012] Through the arrangement of the semiconductor refrigerator and the first temperature-conducting copper plates, the heat generated by the operation of the braking resistance device can be dissipated and cooled when the clamping plates clamp and fix the braking resistance device.

[0013] In a preferred scheme, the lower surface of the mounting frame is provided with a heat dissipation groove, and the inner bottom wall of the mounting frame is embedded with a second temperature-conducting copper plate, and the lower surface of the second temperature-conducting copper plate is provided with heat dissipation fins extending into the heat dissipation groove.

When disassembling, the push rod is pushed to drive the clamping plates to move in the mounting groove, so that the clamping plates on both sides are separated from the braking resistance device. Without the limitation of the clamping plates and the limiting clamping strips, the braking resistance device can be taken out of the mounting frame, which is simple in operation and improves the replacement efficiency of the braking resistance.

[0019] Secondly, under the action of the semiconductor refrigerator, the heat generated by the operation of the braking resistance device can be cooled and dissipated through the first temperature-conducting copper plates. Through the arrangement of the second temperature-conducting copper plate and the heat dissipation fins, the heat generated by the operation of the braking resistance device is transferred to the several heat dissipation fins through the second temperature-conducting copper plate and dissipated in the heat dissipation groove, which further improves the heat dissipation and cooling effect of the device on the braking resistance device.
