[0037] like Figure 2 and Figure 3 As shown, the transmission spindle 30 includes an input end 301 and an output end 302 positioned opposite each other. The transmission spindle 30 is rotatably inserted into the axial hole 112 of the upper housing 11 and engages with the internal gear 13 via at least one engaging key 131 to drive the internal gear 13 to rotate. The output end 302 of the transmission spindle 30 is located outside the pump mounting base 20.

The transmission spindle 30 includes a liquid storage chamber 31, a plurality of guide holes 32, and a passive gear portion 33. The liquid storage chamber 31 extends axially from the input end 301 of the transmission spindle 30 toward the output end 302 of the transmission spindle 30. The plurality of guide holes 32 extend radially from the circumferential surface of the transmission spindle 30 and communicate with the liquid storage chamber 31. The driven tooth portion 33 is located at the input end 301 of the transmission shaft 30 and includes a plurality of meshing teeth disposed on the circumferential surface of the transmission shaft 30 .

[0038] like Figure 2 and Figure 3As shown, the spindle drive assembly 40 includes a drive member mounting base 41 and a spindle drive member 42. The drive member mounting base 41 is used to be combined with a fixed object such as a machine table or a frame to provide support for the present invention. The spindle drive member 42 includes a first end and a second end positioned opposite to each other, as well as a center hole 421, a drive tooth portion 422 and a connecting flange 423. The center hole 421 extends from the first end of the spindle drive member 42 to its second end; the drive tooth portion 422 is located at the first end of the spindle drive member 42 and includes a plurality of meshing teeth provided on the circumferential surface of the center hole 421; the connecting flange 423 is close to the first end of the spindle drive member 42, and the connecting flange 423 is used to be connected to the energy-saving coupling waiting cooling device. The spindle driving member 42 is placed on the transmission spindle 30 with its center hole 421 and can be rotatably inserted into the driving member mounting seat 41. The second end of the spindle driving member 42 is inserted into the axial hole 112 of the upper shell 11 and is connected to the axial hole 112 with its center hole 421. The center hole 421 is connected to the liquid storage chamber 31 of the transmission spindle 30 through multiple guide holes 32; the driving tooth portion 422 of the spindle driving member 42 is engaged with the passive tooth portion 33 of the transmission spindle 30, so that the spindle driving member 42 is connected to the transmission spindle 30 and can drive the transmission spindle 30 to rotate.

[0039] like Figure 10 As shown, the through-type cooling pump 100 of the present invention can be used in conjunction with a motor 71, a device to be cooled 72, a load 73, a cooler 74, a liquid reservoir 75, a first filter 76, a second filter 77, and a gas filter 78. The motor 71 is connected to the device to be cooled 72 and can drive the device to be cooled 72 to rotate; the device to be cooled 72 is connected to the through-type cooling pump 100 and the second filter 77, and the second filter 77 is connected to the liquid reservoir 75; the through-type cooling pump 100 is connected to the load 73, and is connected to the first filter 76 and the gas filter 78; the first filter 76 is connected to the liquid reservoir 75.

[0040] Specifically, the device to be cooled 72 can be an energy-saving coupling, and the load 73 can be a generator. The through-type cooling pump 100 connects the device to be cooled 72 and the load 73, and can be driven by the device to be cooled 72 to drive the load 73. The through-type cooling pump 100 can be connected to the device to be cooled 72, which serves as the energy-saving coupling, via the connecting flange 423 of its spindle drive 42, and connected to the load 73 via the output end 302 of its transmission spindle 30, thereby driving the load 73, which serves as a generator, to generate electricity.

[0041] like Figure 2 and Figure 5As shown, the cooling liquid that has completed cooling the device to be cooled 72 enters its liquid storage chamber 31 through the input end 301 of the transmission spindle 30, flows into the central hole 421 of the spindle driving member 42 through the multiple guide holes 32 of the transmission spindle 30, and flows between the transmission spindle 30 and the spindle driving member 42; then, the cooling liquid enters the cooling pump body 10 again, and enters the chamber 111 of the upper shell 11 of the cooling pump body 10 through the connecting hole 114 of the upper shell 11 of the cooling pump body 10.

[0042] At this time, if Figure 6 As shown, at the inlet recess 121 of the lower housing 12, the teeth of the internal gear 13 and the external gear 14 disengage, generating negative pressure, thereby drawing cooling liquid into the cooling pump body 10. At the outlet recess 122 of the lower housing 12, the teeth of the internal gear 13 and the external gear 14 mesh, increasing the pressure on the incompressible cooling liquid, and the cooling liquid is squeezed out of the cooling pump body 10 through the outlet hole 124. The cooling liquid then enters the lower housing groove 21 of the pump mounting base 20, passes through its outlet hole 23, and is discharged from the circumferential surface of the pump mounting base 20.

[0043] like Figure 10 As shown, the cooling liquid exiting the pump mount 20 first enters the first filter 76 for filtration, removing impurities and iron filings. The cooling liquid then enters the cooler 74 for heat exchange and cooling. The cooled cooling liquid is then sent to the reservoir 75, where it passes through the second filter 77 and is then sent back to the cooling device 72 for continued circulation.

[0044] like Figures 2 to 4 and Figure 5 As shown, when the cooling liquid enters the cooling pump body 10 , a portion of the cooling liquid enters the two receiving holes 22 of the pump fixing base 20 through the two inlet holes 123 of the lower shell 12 .

[0045] like Figure 10 As shown, the hot gas generated by the cooling liquid in the cooling pump body 10 and the pump fixing base 20 is discharged from the hot gas recess 125 of the lower shell 12 through the exhaust hole 24 of the pump fixing base 20. The hot gas enters the gas filter 78 for filtration and is then discharged into the air.

[0046] like Figure 2As shown, two oil seals O and a bushing S are installed in the upper housing 11. One oil seal O is installed at the first end of the upper housing 11 and is placed on the second end of the spindle driver 42 to prevent cooling liquid from flowing out from between the spindle driver 42 and the upper housing 11. The other oil seal O is placed on the transmission spindle 30 to prevent cooling liquid from flowing between the upper housing 11 and the transmission spindle 30. The bushing S is placed on the transmission spindle 30 and is located between the transmission spindle 30 and the upper housing 11, allowing the transmission spindle 30 to rotate smoothly within the upper housing 11.

[0047] like Figure 2 As shown, a bushing S is provided in the lower housing 12 . The bushing S is sleeved on the transmission spindle 30 and is located between the transmission spindle 30 and the lower housing 12 , so that the transmission spindle 30 can rotate smoothly in the lower housing 12 .

[0048] like Figure 2 As shown, a bearing B and an oil seal O are disposed within the pump mount 20. The bearing B is sleeved onto the drive shaft 30, between the drive shaft 30 and the pump mount 20, allowing the drive shaft 30 to rotate smoothly within the pump mount 20. The oil seal O is sleeved onto the drive shaft 30 and located on the underside of the pump mount 20 to prevent cooling liquid from escaping from the pump mount 20.

[0049] like Figure 2 As shown, two bearings B are provided in the driver mounting seat 41. The two bearings B are sleeved on the spindle driver 42, between the driver mounting seat 41 and the spindle driver 42, so that the spindle driver 42 can rotate smoothly in the driver mounting seat 41.

[0050] The through-type cooling pump 100 of the present invention has a drive spindle 30 that engages with the internal gear 13 within the cooling pump body 10, is connected at its output end 302 to the load 73, and is connected to the device to be cooled 72 via the spindle drive member 42 of the spindle drive assembly 40. This allows the motor 71 to simultaneously drive the through-type cooling pump 100 and the load 73. Compared to existing cooling pumps, the through-type cooling pump 100 of the present invention does not require an additional motor dedicated to driving the through-type cooling pump 100. This not only saves energy driving the through-type cooling pump 100 and the load 73, but also reduces the cost of purchasing the motor, achieving the goal of balancing cooling performance with energy conservation.

[0051] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any person with ordinary knowledge in the technical field can make equivalent embodiments by making partial changes or modifications to the technical content disclosed in the present invention without departing from the scope of the technical solution of the present invention, and the equivalent embodiments still fall within the scope of the technical solution of the present invention without departing from the content of the technical solution of the present invention.
