[0019] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0020] After the motor housing has undergone machining on a lathe, it is usually cleaned with degreasing agents. Traditionally, the workpiece is immersed in a cleaning solution, but for larger motor housings, complete immersion is often impossible, requiring multiple turnings to complete the cleaning, resulting in uneven cleaning and low efficiency. While using handheld spray guns can improve cleaning, it causes splashing of dirt, grease, and cleaning agents, polluting the workshop environment. In this embodiment, a transfer trolley 2 transports the motor housing into the spray chamber 3. A water pump 14 sprays the cleaning solution through spray pipes 31 onto the outer wall of the motor housing and nozzles 4 onto the inner wall. Simultaneously, a turntable 21 rotates the motor housing on the transfer trolley 2, thus achieving cleaning. The sprayed solution is filtered and returned through a filter screen 11, preventing impurities from entering the water pump 14, thus achieving continuous recycling of the cleaning solution and a smooth cleaning process.

[0021] Please refer to Figure 1 and Figure 2 As shown, the present invention discloses a large motor housing cleaning device, comprising a chemical tank 1 and a transfer trolley 2; the chemical tank 1 is provided with a filter screen 11, which divides the chemical tank 1 into a sedimentation zone 12 and a pumping zone 13; a spray chamber 3 is provided in the sedimentation zone 12, and a spray pipe 31 is provided in the spray chamber 3; a water pump 14 is provided in the pumping zone 13, and the outlet of the water pump 14 is connected to the spray pipe 31; the transfer trolley 2 reciprocates above the sedimentation zone 12 and the pumping zone 13.

[0022] Working Principle: During cleaning, the transfer trolley 2 is moved above the pumping zone 13. Then, the motor housing is placed onto the transfer trolley 2 using a crane or similar equipment in the workshop. The transfer trolley 2 then transports the motor housing into the spray chamber 3, and the spray chamber 3 is closed. Next, the water pump 14 in the pumping zone 13 draws the cleaning solution to the spray pipe 31, from which the cleaning solution is sprayed onto the motor housing. The spray chamber 3 prevents dirt, grease, and cleaning agents from splashing. The sprayed cleaning solution flows into the sedimentation zone 12, where it is filtered through the filter screen 11, allowing impurities to settle and be collected, preventing them from entering the water pump 14. This ensures continuous recycling of the cleaning solution and efficient operation of the cleaning process.

[0023] In some implementations, please refer to Figure 1 and Figure 3 As shown, the top of the inner cavity of the spray chamber 3 is provided with a nozzle 4 connected to the water outlet pipe of the water pump 14. The nozzle 4 includes a housing 41 and an impeller 42 rotatably disposed inside the housing 41. The housing 41 has at least two water outlet chambers 411 located downstream of the impeller 42. Each water outlet chamber 411 is provided with a water outlet 5 inclined towards the side wall of the spray chamber 3. The impeller 42 is used to periodically change the water inlet area of ​​each water outlet chamber 411. By setting the nozzle 4, the chemical solution can be sprayed towards the inner wall of the motor housing to thoroughly clean the motor housing.

[0024] Meanwhile, during operation, the nozzle 4 uses the chemical solution to drive the impeller 42 to rotate inside the housing 41, thereby periodically changing the water inlet area of ​​each water outlet 411. This causes the flow rate of the chemical solution sprayed from the outlet 5 of each water outlet 411 to change continuously, resulting in a periodic change in the height of the water column sprayed from the outlet 5 of each water outlet 411, thus improving the cleaning effect on the inner wall of the motor housing.

[0025] In some implementations, please refer to Figure 3As shown, the housing 41 is provided with a flushing plate 412 located upstream of the impeller 42, and the flushing plate 412 is provided with a drain outlet 6 facing the blades of the impeller 42. By providing the flushing plate 412 with the drain outlet 6, the medicine entering the housing 41 can flow towards the blades of the impeller 42, thereby driving the impeller 42 to rotate.

[0026] In some implementations, please refer to Figure 3 As shown, the impeller 42 is equipped with a baffle plate 421, and the projected area of ​​the baffle plate 421 on the water outlet chamber 411 intersects with the inlet area of ​​at least one water outlet chamber 411. During rotation, the impeller 42 drives the baffle plate 421 to periodically change the inlet flow rate of the water outlet chamber 411, causing the flow rate of the medicine sprayed from the outlet 5 of each water outlet chamber 411 to continuously change, resulting in a periodic change in the height of the water column sprayed from the outlet 5 of each water outlet chamber 411.

[0027] In some implementations, please refer to Figure 1 As shown, a turntable 21 is rotatably mounted on the transfer trolley 2. During the cleaning process, the turntable 21 drives the motor housing to rotate, so that the spray pipe 31 can spray the cleaning solution into the gaps between the heat dissipation fins on the outer wall of the motor housing, thereby improving the cleaning effect.

[0028] It is worth noting that the transfer trolley 2 is equipped with a separate motor for driving the rotation of the turntable 21, or the rotation of the turntable 21 can be achieved through a transmission gear mechanism connected to the motor of the transfer trolley 2 itself. A waterproof cloth or waterproof cover is provided under the turntable 21 to protect the electrical components of the transfer trolley 2.

[0029] In some implementations, please refer to Figure 4 and Figure 5 As shown, the turntable 21 has limiting blocks 211 distributed around its center point on its surface. After the motor housing is placed on the turntable 21, the limiting blocks 211 are positioned inside the motor housing cavity to prevent the motor housing from moving during the movement of the transfer trolley 2 or during the rotation of the turntable 21.

[0030] In some implementations, please refer to Figure 4 and Figure 5 As shown, the limiting block 211 is slidably disposed on the turntable 21 along the radial direction of the turntable 21, so that the limiting block 211 can be adaptively adjusted according to the inner diameter of the motor housing.

[0031] For details, please refer to Figure 5As shown, the turntable 21 is provided with multiple limiting plates 213, and a limiting space is formed between two limiting plates 213. The limiting block 211 is slidably disposed in the limiting space. The limiting plates 213 and the limiting block 211 are provided with pin holes. The limiting block 211 is fixed on the turntable 21 by passing a pin through the pin holes on the limiting plates 213 and the limiting block 211.

[0032] In some implementations, please refer to Figure 4 and Figure 5 As shown, the turntable 21 has a drainage groove 212 on its surface. The drainage groove 212 can guide the medicine on the turntable 21 into the medicine pool 1.

[0033] In some implementations, please refer to Figure 2 As shown, both the sedimentation zone 12 and the pumping zone 13 on the medicine tank 1 are equipped with trigger switches 7, which are communicatively connected to the transfer trolley 2. During the movement of the transfer trolley 2, the travel distance of the transfer trolley 2 is controlled by the trigger switches 7.

[0034] It is worth noting that the trigger switch 7 can be a toggle switch, photoelectric switch, push button switch, etc.

[0035] In some implementations, please refer to Figure 2 As shown, the medicine pool 1 is equipped with a heating wire 15. The heating wire 15 can be used to heat the medicine in the medicine pool 1 to improve the cleaning effect of the medicine.

[0036] It is worth noting that the temperature of the medicinal water in the medicine pool 1 is controlled between 60℃ and 80℃.

[0037] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
