Detailed Description

Referring to fig. 1 to 3, in an embodiment of the present utility model, a motor cooling structure includes a motor body 1 and a housing 2 for covering the motor body 1. The provision of the housing 2 enables the cooled liquid to cyclically cool the motor 1. The housing 2 is provided with a filter mechanism 3 for filtering the liquid.

The filter mechanism 3 includes a case 31 fixedly attached to the outer circumferential wall of the motor main body 1. A plurality of slot plates 32 are linearly distributed on the inner wall of the case 31. The plurality of slot plates 32 are respectively inserted with a filter plate 33 for filtering liquid, and a cleaning component 34 for cleaning the filter plate 33 is arranged on the inner wall of the rear side of the box body 31. Each of the slot plates 32 is divided into two pairs corresponding up and down for the plug-in fitting of the filter plates 33.

Holes are formed in the front and rear walls of the case 31. The rear holes are connected with the discharge pipe of the shell 2 through bent pipes. A discharging pipe for discharging liquid is arranged in the front hole. A notch is formed in the side shell wall of the box body 31, and a box cover 35 for plugging is mounted in the notch through a screw. The box cover 35 is provided to repair and maintain the respective structures inside the box body 31, and to fix the filter plate 33 after closing the box cover.

The cleaning assembly 34 is composed of a fixed plate 341, an impeller 342, a disc 343, an adjusting plate 344 and a brush plate 345. The fixed plates 341 are fixedly connected to the inner wall of the rear side of the box 31, and are located on the upper side and the lower side of the curved tube. The impeller 342 is located between the two fixed plates 341, and both ends thereof are provided with rotating shafts, and one ends of the rotating shafts, which are far away from the impeller 342, respectively pass through the corresponding fixed plates 341.

The disc 343 and the adjusting plate 344 each comprise two discs, wherein the plurality of discs 343 are respectively disposed on the corresponding rotating shafts. A plurality of adjustment plates 344 are movably coupled to respective ones of the disks 343.
