At the same time, the heat generated by the insertion shaft 210 and the transmission shaft 312 when rotating inside the ventilation rack 219 can be introduced by the fan 209. The airflow makes the airflow flow in the circulation slot 222, so that the heat generated by the rotation is discharged to the outside by the gas;

[0049] Embodiment 2:

[0050] Reference Figure 2 - Figure 7 , compared with the first embodiment, the difference is that: the upper surface of the load-bearing plate 101 is slidably connected with a moving rod 215, the upper surface of the moving rod 215 is fixedly connected with a fixed machine base 214, the lower surface of the fixed machine base 214 is slidably connected to the upper surface of the load-bearing plate 101, the upper surface of the fixed machine base 214 is fixedly connected with a driving motor 213, and the upper surface of the driving motor 213 is fixedly connected with a heat dissipation fin plate 211, wherein the fixed machine base 214 can be quickly disassembled through the moving rod 215, and then when the driving motor 213 fails, it is not necessary to disassemble the arc frame 201 on its outer side, so that the equipment can be quickly maintained and the working efficiency of the equipment is improved. Furthermore, the heat dissipation fin plate 211 on the outer surface of the driving motor 213 is used to guide the temperature generated by its operation to the outside.

[0051] Furthermore, U-shaped snap-fit ​​frames 225 are fixedly connected on both sides of the fixed base 214, and a rubber snap-fit ​​pad 217 is fixedly connected to one side of the U-shaped snap-fit ​​frame 225 close to the T-shaped slide 204, and a carrying rod 216 is inserted into the U-shaped snap-fit ​​frame 225, and a side of the carrying rod 216 away from the driving motor 213 is fixedly connected to one side of the T-shaped slide 204, wherein the carrying rod 216 is snapped with the rubber snap-fit ​​pad 217, so that when the device is working, the vibration generated by the device during operation is offset by the rubber snap-fit ​​pad 217, thereby reducing the resonance degree of the arc frame 201 to a certain extent.

[0052] Furthermore, mounting plates are fixedly connected on both sides of the fixed base 214, and the upper surface of the mounting plates is connected to the load-bearing plate 101 by bolts, one end of the output shaft of the driving motor 213 is fixedly connected to the insertion shaft 210, and the side of the driving motor 213 close to the insertion shaft 210 is fixedly connected to a conical air induction block 212, one side of the insertion shaft 210 is inserted into one side of the ventilation frame 219, and a butterfly block is provided at the end of the insertion shaft 210 away from the driving motor 213, wherein the airflow discharged from the ventilation frame 219 is diverted by the conical air induction block 212, and then the airflow is fully dispersed to a certain extent, so that the airflow conducts and discharges the heat generated by the driving motor 213.

[0053] Furthermore, a protective frame 203 is fixedly connected to one side of the U-shaped load-bearing frame 207, a sound-absorbing cotton 205 is fixedly connected to the inner surface of the protective frame 203, a fan 209 is fixedly connected to the side of the U-shaped load-bearing frame 207 close to the protective frame 203, and a filter plate 206 is fixedly connected to one side of the protective frame 203, wherein the sound-absorbing cotton 205 and the fan 209 cooperate with each other to make the sound-absorbing cotton 205 absorb the noise generated by the fan 209, thereby reducing the noise of the equipment to a certain extent, and filtering the dust in the air through the filter plate 206 to prevent the dust carried in the air from adhering to the ventilation frame.

[0054] Furthermore, a placement groove 221 is provided on the upper surface of the ventilation rack 219, and a lubricating oil tank 208 is snap-connected in the placement groove 221, a pulling handle 218 is fixedly connected to the upper surface of the lubricating oil tank 208, a circulation groove 222 is provided on the upper surface of the ventilation rack 219, and a one-way valve 223 is snap-connected in the circulation groove 222, the lower surface of the lubricating oil tank 208 and the upper surface of the one-way valve 223 are snap-connected to each other, and an injection pipe 220 is inserted into the upper surface of the lubricating oil tank 208, wherein the transmission shaft 312 and the insertion shaft 210 are fully lubricated during the rotation process through the lubricating oil tank 208, thereby reducing the mechanical loss of the equipment transmission to a certain extent.

[0055] Working principle: First, two groups of T-shaped bearing seats 102 are symmetrically distributed under the bearing plate 101 to form a stable support base. The concave bearing block 104 is embedded with the guide groove 308 to guide the liquid from the water inlet pipe 303 to the impeller 305. At the same time, the ring plate 316 is used to enhance the structural rigidity. The transmission shaft 312 and the insertion shaft 210 are quickly docked through the butterfly groove 224. There is no need to disassemble the entire structure during maintenance. The driving motor 213 slides away from the pump body through the moving rod 215, so that it can be quickly disassembled and maintained to a certain extent, and the rubber clamping pad 217 is used to buffer vibration and prevent component wear;

[0056] Secondly, the fan 209 filters the external air through the filter plate 206 and then sucks it into the ventilation rack 219. The airflow flows through the transmission shaft 312 and the insertion shaft 210 through the circulation slot 222, taking away the friction heat, and intercepts the dust in the air through the filter plate 206, thereby extending the life of the equipment to a certain extent. The heat dissipation area is increased through the heat dissipation fin plate 211, so that the airflow is constantly in contact with the surface of the heat dissipation fin plate 211, and then the heat dissipation treatment is performed again. The noise of the fan 209 and the gear meshing is absorbed by the sound-absorbing cotton 205, and the lubricating oil drips into the bearing of the transmission shaft 312 through the one-way valve 223 to reduce the friction heat.

[0057] Finally, the driving motor 213 drives the active gear 302 through the insertion shaft 210, and the secondary gear 301 drives the impeller 305 to rotate synchronously. The liquid enters the liquid tank 307 through the water inlet pipe 303. The impeller 305 rotates to generate centrifugal force, and the liquid is pressurized and transported to the drain pipe 310 through the guide groove 308. When the driving motor 213 fails, the sliding moving rod 215 can separate it from the pump body without disassembling the arc frame 201.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
