One end of the cooling tank body 110 is fixedly connected with an inlet pipe 111 in an extending manner, the other end of the cooling tank body 110 is fixedly connected with a drain pipe 112 in an extending manner, the inlet pipe 111 and the drain pipe 112 are both communicated with the cooling tank body 110, and the filtering mechanism 300 is arranged in the inlet pipe 111.

When cooling down driving motor 100, with inlet tube 111 and the water supply installation intercommunication under the mine, make water supply installation then with water through inlet tube 111 get into cooling tank body 110 in, after water gets into inlet tube 111, filtering mechanism 300 filters water to it follows the circumstances emergence that water got into cooling tank body 110 and will cool off tank body 110 jam to reduce the impurity of aquatic. The water in the cooling tank body 110 is finally discharged out of the cooling tank body 110 through the water discharge pipe 112, and the water discharge pipe 112 can enable the position where the water flows out to have a certain distance from the driving motor 100, so that the influence of the water on the normal operation of the driving motor 100 is reduced.

Referring to fig. 2 and 3, the filter mechanism 300 includes a filter plate 310 and a cleaning assembly 320 for cleaning the filter plate 310, the filter plate 310 is arranged perpendicular to the direction of the water flow in the inlet pipe 111, and the filter plate 310 is fixedly coupled to the inner wall of the inlet pipe 111. The sweeping assembly 320 includes brushes 321 and scrapers 322, and the scrapers 322 and 321 are rotatably connected to the filter plate 310. And the brush 321 is arranged on one side of the filter plate 310 departing from the nozzle of the water inlet pipe 111, the bristles of the brush 321 are abutted against the filter plate 310, and when the brush 321 and the filter plate 310 rotate relatively, the brush 321 cleans the filter plate 310. The scraping plate 322 is disposed on one side of the filtering plate 310 facing the nozzle of the water inlet pipe 111, and one side of the scraping plate 322 near the filtering plate 310 abuts against the filtering plate 310, and when the scraping plate 322 rotates relative to the filtering plate 310, the scraping plate 322 scrapes the filtering plate 310.

Referring to fig. 2 and 3, a synchronizing assembly 400 for synchronously driving the brush 321 and the scraper 322 is installed on the filter plate 310, the synchronizing assembly 400 includes a fan blade 410 and a rotating shaft 420, the rotating shaft 420 is rotatably connected to the filter plate 310, one end of the rotating shaft 420 is vertically and fixedly connected to the fan blade 410, and the other end of the rotating shaft 420 penetrates through the filter plate 310 and is vertically and fixedly connected to the brush 321. The scraping plate 322 is vertically and fixedly connected with the rotating shaft 420, and the scraping plate 322 is disposed between the fan blades 410 and the filter plate 310. The bottom of the water inlet pipe 111 is communicated with and fixedly provided with a dust collecting pipe 113 corresponding to the scraper 322, one end of the dust collecting pipe 113 far away from the water inlet pipe 111 is provided with a sealing plug 114, and one end of the sealing plug 114 is threaded into the dust collecting pipe 113.

When water enters the cooling tank 110 through the water inlet pipe 111, the filter plate 310 filters the water, and then impurities in the water are blocked by the filter plate 310. When water enters the water inlet pipe 111, water and the fan blade 410 are collided in front, so that the fan blade 410 is driven by the water, the fan blade 410 drives the rotation and the filter plate 310 to rotate relatively, meanwhile, the scraper blade 322 and the hairbrush 321 and the filter plate 310 rotate relatively, and then the hairbrush 321 and the scraper blade 322 clean the filter plate 310. The foreign substances scraped by the scraper 322 move toward the bottom of the water inlet pipe 111 by its own weight while the foreign substances move into the dust collection pipe 113 when the scraper 322 moves to the vertical state. When the amount of the foreign substances accumulated in the dust collection pipe 113 reaches a certain amount, the sealing plug 114 is unscrewed, and the foreign substances in the dust collection pipe 113 are discharged out of the dust collection pipe 113 by its own weight.

The implementation principle of the mine main drainage pump with the cooling function is as follows: when the main drainage pump is used for pumping water in a mine, the driving motor 100 is started, the driving motor 100 drives the pump body 200 to rotate, and then the pump body 200 pumps the water in the mine. When the driving motor 100 needs to be cooled, the water supply device is communicated with the water inlet pipe 111, and then the water enters the cooling tank body 110 through the water inlet pipe 111. When water enters the cooling tank 110 through the water inlet pipe 111, the water generates a frontal impact on the fan blade 410, the fan blade 410 drives the rotating shaft 420 to rotate under the action of the water, and the scraper 322 and the brush 321 synchronously rotate, so that the scraper 322 and the brush 321 clean the filter plate 310. When the scraper 322 moves to the vertical state, the foreign substances scraped by the scraper 322 fall down by its own weight, thereby allowing the foreign substances to fall into the dust collection pipe 113. The water filtered by the filter plate 310 enters the cooling tank body 110, the water flows in the cooling tank body 110 along the arrangement direction of the cooling tank body 110, meanwhile, the water takes away heat generated by the driving motor 100, and finally, the water in the cooling tank body 110 is discharged out of the cooling tank body 110 through the drain pipe 112.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
