[0036] See also Figure 1 In an embodiment of the present application, a mining motor 10 is provided, wherein the mining motor 10 is cooled by water. The mining motor 10 provided in this embodiment can improve the technical problem of water leakage at the water inlet of the motor in the prior art.
[0037] In this embodiment, please refer to Figures 2 to 7 The mining motor 10 includes a motor base 100, a motor body 200, and a front cover 300. A plurality of first water channels 110 are provided on the motor base 100. The motor body 200 is disposed inside the motor base 100; the motor body 200 is used to output power. The front cover 300 is connected to the motor body 200, and a first water inlet 310 and a first water outlet are provided on the front cover 300. The first water inlet 310 is connected to one of the first water channels 110, and the first water outlet is connected to another of the first water channels 110. When water enters the first water inlet 310, the water can flow through the plurality of first water channels 110 in sequence. The first water inlet 310 forms a plurality of first water inlets 311 on the outer surface of the front cover 300, and the first water outlet forms a plurality of first water outlets 321 on the outer surface of the front cover 300.
[0038] When water enters the first water inlets 311, it gathers in the first water inlet channel 310 and is then introduced through one of the first water channels 110. The water then passes through the first water channels 110 in sequence before entering the first water outlet channel and finally being discharged through the first water outlets 321. In this embodiment, the first water channels 110 are arranged around the motor body 200 to uniformly distribute heat and cooling to the motor body 200.
[0039] As described above, in this mining motor 10, since the first water inlet 310 forms multiple first water inlets 311 on the front cover 300, while ensuring sufficient water intake, the diameter of the first water inlet 311 can be reduced compared to the water inlet of the prior art, thereby increasing the distance between the first water inlet 311 and the outer contour of the front cover 300, thereby improving the technical problem of water leakage at the water inlet in the prior art. Similarly, since the first water outlet forms multiple first water outlets 321 on the front cover 300, while ensuring that the water output meets the demand, the diameter of the first water outlet 321 can be reduced compared to the water outlet of the prior art, thereby increasing the distance between the first water outlet 321 and the outer contour of the front cover 300, thereby improving the technical problem of water leakage at the water inlet in the prior art.
[0040] Optionally, in this embodiment, the diameter of the first water inlet 311 is 15.8 mm; the diameter of the first water outlet 321 is 15.8 mm. In other words, the diameters of the first water inlet 311 and the first water outlet 321 meet the G3 / 8 standard; that is, the first water inlet 311 and the first water outlet 321 can adopt a pipe thread inner hole G3 / 8 model. It is worth noting that in the prior art, the diameter of the water inlet is generally set to the G1 / 2 standard. Based on this, compared with the prior art, the size of the first water inlet 311 and the first water outlet 321 provided in this embodiment is reduced, thereby increasing the distance between the first water inlet 311 and the first water outlet 321 and the outer contour of the front end cover 300, thereby improving the problem of easy water leakage at the water inlet in the prior art.
[0041] Of course, in other embodiments of the present application, the diameters of the first water inlet 311 and the first water outlet 321 may also adopt other values, as long as they are less than G1 / 2. It is worth noting that after adjusting the diameters of the first water inlet 311 and the first water outlet 321, the number of the first water inlet 311 and the first water outlet 321 can be adjusted according to the aperture sizes of the first water inlet 311 and the first water outlet 321 to meet sufficient water inlet and water outlet requirements.
[0042] Furthermore, the distance between the first water inlet 311 and the outer contour of the front end cover 300 is 13 mm; the distance between the first water outlet 321 and the outer contour of the front end cover 300 is also 13 mm. Compared to the 8 mm distance between the water inlet and the outer contour of the end cover in the prior art, the distance between the first water inlet 311 and the first water outlet 321 and the outer contour of the front end cover 300 is significantly increased, thereby improving the technical problem of water leakage at the water inlet in the prior art.
[0043] It should be understood that in other embodiments of the present application, when the apertures of the first water inlet 311 and the first water outlet 321 are adjusted, the distances between the first water inlet 311 and the first water outlet 321 and the outer contour of the front end cover 300 may change. Based on this, it is worth noting that the above purpose can be achieved by simply ensuring that the distances between the first water inlet 311 and the first water outlet 321 and the outer contour of the front end cover 300 are greater than 8 mm.
[0044] In this embodiment, the plurality of first water inlets 311 and the plurality of first water outlets 321 are all located on a first circumferential path, and the center of the first circumferential path is the center of the front end cover 300 .
[0045] Among them, by reducing the aperture of the first water inlet 311 and the first water outlet 321, the processing difficulty of the first water inlet 311 and the first water outlet 321 can be reduced, which is conducive to improving the processing accuracy; and further arranging multiple first water inlets 311 and multiple first water outlets 321 on the first circular path can further reduce the processing difficulty of the first water inlet 311 and the first water outlet 321 and improve the processing accuracy.
[0046] In this embodiment, preferably, the number of the first water inlets 311 is two, and the number of the first water outlets 321 is two.
[0047] In this embodiment, a plurality of second water channels 120 are further provided on the motor base 100; the mining motor 10 also includes a rear end cover 400, on which a second water inlet and a second water outlet are provided; the second water inlet is connected to one of the second water channels 120, and the second water outlet is connected to another second water channel 120, and when water enters the second water inlet, the water can flow through the plurality of second water channels 120 in sequence; wherein, the second water inlet forms a plurality of second water inlets 410 on the outer surface of the rear end cover 400, and the second water outlet forms a plurality of second water outlets 420 on the outer surface of the rear end cover 400.
[0048] It should be noted that the water cooling system formed by the second water inlet and second water outlet opened on the rear end cover 400 and the multiple second water channels 120 on the motor base 100, and the water cooling system formed by the first water inlet 310 and first water outlet opened on the front end cover 300 and the multiple first water channels 110 on the motor base 100 are independent of each other. The motor body 200 can be cooled by two independent cooling systems, thereby achieving the purpose of improving the heat dissipation and cooling effect.
[0049] Among them, multiple second water inlets 410 and multiple second water outlets 420 are also arranged on the rear end cover 400, which can reduce the diameter of the second water inlet 410 and the second water outlet 420 relative to the existing technology, thereby increasing the distance between the second water inlet 410 and the second water outlet 420 and the outer contour of the rear end cover 400, which can further improve the technical problem of easy water leakage at the water outlet in the existing technology.
[0050] Optionally, the diameter of the second water inlet 410 is 15.8 mm; the diameter of the second water outlet 420 is 15.8 mm. In other words, the diameters of the second water inlet 410 and the second water outlet 420 meet the G3 / 8 standard; that is, the second water inlet 410 and the second water outlet 420 can adopt a pipe thread inner hole G3 / 8 model. In the prior art, the diameter of the water inlet is generally set to the G1 / 2 standard. Based on this, compared with the prior art, the size of the second water inlet 410 and the second water outlet 420 provided in this embodiment is reduced, thereby increasing the distance between the second water inlet 410 and the second water outlet 420 and the outer contour of the rear end cover 400, thereby improving the problem of easy water leakage at the water inlet in the prior art.
[0051] Furthermore, the distance between the second water inlet 410 and the outer contour of the rear end cover 400 is 13 mm; the distance between the second water outlet 420 and the outer contour of the rear end cover 400 is also 13 mm. Compared to the 8 mm distance between the water inlet and the outer contour of the end cover in the prior art, the distance between the second water inlet 410 and the second water outlet 420 and the outer contour of the rear end cover 400 is significantly increased, thereby improving the technical problem of water leakage at the water inlet in the prior art.
[0052] It should be understood that in other embodiments of the present application, when the apertures of the second water inlet 410 and the second water outlet 420 are adjusted, the distances between the second water inlet 410 and the second water outlet 420 and the outer contour of the rear end cover 400 may change. Based on this, it is worth noting that the above purpose can be achieved by simply ensuring that the distances between the second water inlet 410 and the second water outlet 420 and the outer contour of the rear end cover 400 are greater than 8 mm.
[0053] Optionally, the plurality of second water inlets 410 and the plurality of second water outlets 420 are all located on a second circumferential path, and the center of the second circumferential path is the center of the rear end cover 400 .
[0054] Among them, by reducing the aperture of the second water inlet 410 and the second water outlet 420, the processing difficulty of the second water inlet 410 and the second water outlet 420 can be reduced, which is conducive to improving the processing accuracy; and further arranging multiple second water inlets 410 and multiple second water outlets 420 on the second circumferential path can further reduce the processing difficulty of the second water inlet 410 and the second water outlet 420 and improve the processing accuracy.
[0055] In this embodiment, preferably, the number of the second water inlets 410 is two, and the number of the second water outlets 420 is two.
[0056] In summary, in this mining motor 10, since the first water inlet 310 forms multiple first water inlets 311 on the front cover 300, while ensuring sufficient water intake, the diameter of the first water inlet 311 can be reduced compared to the water inlet of the prior art, thereby increasing the distance between the first water inlet 311 and the outer contour of the front cover 300, thereby improving the technical problem of water leakage at the water inlet in the prior art. Similarly, since the first water outlet forms multiple first water outlets 321 on the front cover 300, while ensuring that the water output meets the demand, the diameter of the first water outlet 321 can be reduced compared to the water outlet of the prior art, thereby increasing the distance between the first water outlet 321 and the outer contour of the front cover 300, thereby improving the technical problem of water leakage at the water inlet in the prior art. Furthermore, multiple second water inlets 410 and multiple second water outlets 420 are also provided on the rear end cover 400, which can reduce the diameter of the second water inlet 410 and the second water outlet 420 relative to the existing technology, thereby increasing the distance between the second water inlet 410 and the second water outlet 420 and the outer contour of the rear end cover 400, and can further improve the technical problem of easy water leakage at the water outlet in the existing technology.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
