The air enters the cooling cover 2 through the vent 24, and the contact with the cooling water pipe 7 can cool the air, which can improve the heat dissipation effect of the motor body 1. The water then flows back to the water tank 3 through the return pipe 8 for recycling.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown: the wind heat dissipation mechanism includes a casing 9 fixed to the rear end of the motor body 1, the rear end of the main shaft of the motor body 1 penetrates into the casing 9 and is fixedly connected with a double groove wheel 10, one side of the casing 9 is inserted and rotatably connected with two symmetrically arranged rotating rods 11, one end of the two rotating rods 11 is fixedly connected with a transmission wheel 12, and the double groove wheel 10 is respectively connected to the two transmission wheels 12 through two transmission belts 13 for transmission, and both sides of the motor body 1 are fixedly connected with a bellows 14 arranged in communication with the interior thereof, one end of the two rotating rods 11 penetrates into the two bellows 14 respectively and is fixedly connected with a first bevel gear 15, a support frame 16 is fixedly connected in the bellows 14, a rotating shaft 17 is inserted and rotatably connected on the supporting frame 16, one end of the rotating shaft 17 is fixedly connected with a second bevel gear 18 meshing with the first bevel gear 15, and the other end of the rotating shaft 17 is fixedly connected with a wind impeller 19, and an end of the bellows 14 away from the motor body 1 is fixedly connected with an air outlet 20;

[0026] When the motor body 1 is working, its main shaft end rotates, thereby driving the double-grooved wheel 10 to rotate. Since the double-grooved wheel 10 is transmitted to the two transmission wheels 12 through the transmission belt 13, it drives the two rotating rods 11 to rotate at the same time. Since the two first bevel gears 15 are respectively engaged with the two second bevel gears 18, the fan impellers 19 on the two rotating shafts 17 are driven to rotate at the same time, and the heat inside the motor body 1 is discharged from the air outlet 20, thereby enhancing the air circulation and improving the heat dissipation effect of the motor body 1 when it is working.

[0033] When the motor body 1 needs to dissipate heat during operation, first, the refrigerator 22 is started to work, the cooling fins 23 are cooled, and the water in the water tank 3 can be cooled. At the same time, the submersible pump 5 is started to work, and the water in the water tank 3 is introduced into the cooling water pipe 7 through the water guide pipe 6. The air enters the cooling cover 2 through the vent 24, and the air can be cooled by contacting with the cooling water pipe 7, which can improve the heat dissipation effect of the motor body 1. The water is then returned to the water tank 3 through the return pipe 8 for recycling.
