[0001] The present invention relates to the technical field of load motor cooling, in particular to a cooling device for a load motor. Background Art

[0002] A load motor refers to an electric motor that is actually working and outputting mechanical power to drive a specific external resistance or device; it is mostly in a working state of running with load; referring to the Chinese patent with the publication number "CN117650668B" titled "A Dual-Cooling Motor", the patent points out that in the prior art, when cooling the motor, most of the heat is dissipated by fans, which has a relatively simple function and cannot meet the heat dissipation requirements of the motor in long-term operation. The overall heat dissipation efficiency is low, resulting in the need for frequent manual maintenance and auxiliary heat dissipation treatment, which increases the labor intensity; however, the device still has problems with poor heat dissipation effect and equipment stability. To this end, we propose a cooling device for a load motor to solve the above problems. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention provides a cooling device for a load motor, which solves the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A cooling device for a load motor includes a load motor body, an output shaft body is rotatably connected to the load motor body, a sealing bottom plate is fixedly installed at one end of the load motor body away from the output shaft body, and a cooling assembly is installed inside the sealing bottom plate; The cooling assembly includes a central positioning ring frame, which is fixedly installed inside the sealing bottom plate.

[0008] Preferably, a distance is left between the plurality of heat-conducting terminals and the inner wall of the load motor body.

[0009] Preferably, a cleaning assembly is provided on the outer side of the middle positioning ring frame for cleaning impurities attached to the end of the heat-conducting pipe and the surface of the heat-dissipating fins.

[0012] Preferably, when the coolant passes through the liquid guide end and enters the interior of the sealing cover plate and contacts multiple heat dissipation fins, the heat dissipation fins can be subjected to force to drive multiple heat conduction pipes to rotate inside the corresponding annular limiting sleeves. As the heat conduction pipes and the heat dissipation fins rotate and contact the corresponding elastic cleaning scrapers, the heat conduction pipes and the heat dissipation fins can be cleaned when the cooling water circulates, further ensuring the heat exchange effect and improving the maintenance convenience of the equipment.
