DETAILED DESCRIPTION

[0018] Combined with Figure 1-Figure 7 The motor with autonomous cooling function is composed of a cover 10, a stator 13 and a fan cover 14, wherein a terminal box 12 is fixedly installed on the stator 13, two machine bases 19 are symmetrically fixed on both sides of the stator 13, a rotor is installed in the stator 13, and the rotor includes a rotating shaft 11, the rotating shaft 11 rotates through the cover 10 through a bearing, the end of the rotating shaft 11 is rotatably arranged on the fan cover 14 and fixed with a fan 34, and a plurality of fins 15 are fixed on the stator 13 for enhancing heat dissipation; The power is connected through the junction box 12. After the power is connected, the fan 34 is driven to rotate to cool the stator 13 and the cover 10. A liquid cooling assembly is also installed on both sides of the stator 13, and the liquid cooling assembly includes a No. 1 liquid storage structure 50 fixedly installed with the cover body 10 and a No. 2 liquid storage structure 60 fixed in the wind hood 14, the No. 1 liquid storage structure 50 is fixedly connected with the No. 2 liquid storage structure 60 through a plurality of No. 1 water pipes 16, the No. 2 liquid storage structure 60 is fixedly connected with a No. 2 water pipe 28, the No. 2 water pipe 28 is fixedly connected with a water pump 27, the water pump 27 is fixedly installed on the wind hood 14, the water pump 27 is fixedly connected with the No. 1 liquid storage structure 50 through the No. 3 water pipe 35, after the water pump 27 is started, the coolant in the No. 2 liquid storage structure 60 can be transported from the No. 3 water pipe 35 to the No. 1 liquid storage structure 50 through the No. 2 water pipe 28, and the coolant in the No. 1 liquid storage structure 50 flows from each of the No. 1 water pipes 16 to the No. 2 liquid storage structure 60, so as to realize the circulation of the coolant; The bearing inside the cover 10 is prone to overheating. To solve this problem, the applicant has optimized the first liquid storage structure 50 and the second liquid storage structure 60, specifically: The No. 1 liquid storage structure 50 includes a No. 1 fixed ring 26 fixed to the cover body 10 and a No. 1 movable ring 24 slidably sleeved on the cover body 10, and a No. 1 membrane 25 and a No. 2 membrane 37 are fixedly arranged between the No. 1 movable ring 24 and the No. 1 fixed ring 26, wherein the No. 1 movable ring 24, the No. 1 fixed ring 26, the No. 1 membrane 25 and the No. 2 membrane 37 together form a No. 1 liquid storage chamber 36, and the No. 1 liquid storage chamber 36 is filled with coolant; The No. 2 liquid storage structure 60 includes a No. 2 fixed ring 29 fixed to the stator 13, a No. 2 movable ring 31 is arranged on one side of the No. 2 fixed ring 29, the No. 2 movable ring 31 is slidably connected to the stator 13, and a No. 3 membrane 30 and a No. 4 membrane 38 are fixed between the No. 2 movable ring 31 and the No. 2 fixed ring 29, wherein the No. 2 fixed ring 29, the No. 2 movable ring 31, the No. 3 membrane 30 and the No. 4 membrane 38 together form a No. 2 liquid storage chamber 39, and the No. 2 liquid storage chamber 39 is filled with coolant; One end of the No. 2 water pipe 28 is fixedly connected to the No. 2 liquid storage chamber 39, one end of the No. 3 water pipe 35 is fixedly connected to the No. 1 liquid storage chamber 36, and both ends of the No. 1 water pipe 16 are fixedly connected to the No. 2 liquid storage chamber 39 and the No. 1 liquid storage chamber 36 respectively; A fixing plate 21 is fixed on one of the machine bases 19, and an electric telescopic rod 22 is fixedly installed on the fixing plate 21. The electric telescopic rod 22 controls the extension and retraction of the hydraulic rod. The end of the hydraulic rod controlled by the electric telescopic rod 22 is fixed with a connecting plate 23, and the connecting plate 23 is fixed to the first moving ring 24. An intermediate rod 18 is fixed on the connecting plate 23, and the other end of the intermediate rod 18 is fixed to the second moving ring 31. The extension and retraction of the electric telescopic rod 22 can drive the first moving ring 24 and the second moving ring 31 to move to one side at the same time through the connecting plate 23 and the intermediate rod 18, so that the coolant in the second liquid storage chamber 39 is transferred to the second liquid storage chamber 39 through the first moving ring 24. The water pipe 16 is squeezed into the No. 1 liquid storage chamber 36, so that the coolant in the No. 1 liquid storage chamber 36 increases, or the coolant in the No. 1 liquid storage chamber 36 is squeezed into the No. 2 liquid storage chamber 39 through the No. 1 water pipe 16, so that the coolant in the No. 1 liquid storage chamber 36 decreases. A temperature sensor is installed at the bearing position in the cover body 10. When the temperature is detected to be too high, the coolant in the No. 2 liquid storage chamber 39 is squeezed into the No. 1 liquid storage chamber 36 through the No. 1 water pipe 16, so that the coolant in the No. 1 liquid storage chamber 36 increases, thereby immediately cooling the position of the shaft 11 quickly, effectively dealing with the dangerous situation of overheating of the bearing in the shaft 11; Furthermore, when the bearing temperature reaches a critical value, it will indirectly cause the overall temperature of the motor to be too high. In order to cope with this situation, the applicant installed a number of spray assemblies in the No. 2 liquid storage chamber 39, and the spray assembly includes a liquid collecting cylinder 47 fixed on the inner side of the No. 2 movable ring 31, and a spraying groove 46 is provided in the liquid collecting cylinder 47.

The end of the liquid collecting cylinder 47 is fixedly connected with an atomizing nozzle 45 extending out of the outside. The spraying groove 46 is filled with coolant. When the No. 2 movable ring 31 is further pulled toward the cover body 10, the push head 40 will contact the No. 2 fixed ring 29 (when the detection result of the temperature sensor does not reach the critical value, the push head 40 will not contact the No. 2 fixed ring 29), thereby being pushed by the No. 2 fixed ring 29, and the spring 42 is stretched. The piston 43 moves along the spraying groove 46 to first block the collecting port 44, and then the piston 43 pushes the coolant in the spraying groove 46 out of the atomizing nozzle 45. The coolant sprayed from the atomizing nozzle 45 is atomized. Under the blowing action of the fan 34, the atomized coolant is sprayed to various positions on the stator 13, thereby realizing rapid evaporation and heat dissipation.

[0019] In order to achieve a better heat dissipation effect, each of the first water pipes 16 is installed between the fins 15 .

[0020] Among them, the benefit of setting the second liquid storage structure 60 is that as much coolant as possible can be cooled by the blowing effect of the fan 34 at the same time.

[0021] The applicant would like to particularly point out that a control box 20 fixed to the base 19 is provided on one side of the fixing plate 21, and the control box 20 is used to control the temperature of the temperature sensor received by the present application to control the operation of the electric telescopic rod 22, and the control program may consider using a relatively stable PLC.

[0022] For easy installation, at least two guide pieces 32 are fixed on the second moving ring 31 . The guide pieces 32 are provided with holes and penetrated by guide bars 33 . The guide bars 33 are fixed to the stator 13 .
