The side walls of the oil cylinder 301 above and below the annular partition plate 303 are respectively sealed with an oil drain straight pipe 304 and an oil inlet straight pipe 305. The oil drain straight pipe 304 is located in the oil cylinder One end of the interior of 301 is connected to a first oil guide hose 304a, one end of the first oil guide hose 304a is located in the cylindrical filter 303a, an oil pump 306 is provided on the outer wall of the housing 100, an end of the oil discharge straight pipe 304 located outside the oil barrel 301 is connected to the oil inlet of the oil pump 306 through a second oil guide hose 304b, the oil discharge port of the oil pump 306 is connected to a third oil guide hose 306a, and an end of the oil inlet straight pipe 305 located outside the oil barrel 301 is provided with a fourth oil guide hose 305a, the second cleaning mechanism 400 includes a cleaning mechanism located inside the cleaning chamber 101 and facing the clamping assembly The spray block 401 of 203 has a cavity structure inside. A plurality of spray holes 401a are evenly distributed on the end face of the spray block 401 facing the clamping assembly 203. The back of the spray block 401 is fixed to the inner wall of the shell 100 through the connecting block 402. A liquid storage tank 403 and a liquid pump 404 are provided on the outside of the shell 100. The bottom of the liquid storage tank 403 and the liquid inlet of the liquid pump 404 are connected through a first drain pipe 404a. The liquid outlet of the liquid pump 404 is connected to a second drain pipe 404b. One end of the second drain pipe 404b passes through the shell 100 and is connected to the inner cavity of the spray block 401.

[0018] The oil pump that needs to be cleaned is firmly clamped by the clamping assembly 203, and the liquid pump 404 is turned on. The liquid pump 404 pumps the clean water in the liquid storage tank 403 into the inner cavity of the spray block 401 through the first liquid discharge pipe 404a and the second liquid discharge pipe 404b in sequence, and the surface of the oil pump shell is sprayed and rinsed by multiple liquid spray holes 401a evenly distributed on the end surface of the spray block 401. The rotating motor 201 is turned on, and the rotating motor 201 drives the oil pump to rotate through the rotating shaft 202 so that the oil pump shell can be fully sprayed and rinsed. After the oil pump shell is cleaned, the rotating motor 201 and the liquid pump 404 are turned off, and the end of the third oil guide hose 306a is connected to the oil inlet of the oil pump, and the end of the fourth oil guide hose 305a is connected to the oil discharge port of the oil pump. The oil pump 306 is turned on, and the oil pump 306 sends the clean oil filtered by the cylindrical filter 303a to the oil pump cavity for flushing and cleaning through the first oil guide hose 304a, the oil discharge straight pipe 304, the second oil guide hose 304b and the third oil guide hose 306a in sequence. The impurities and dirt in the oil pump cavity are mixed with the oil and discharged to the inside of the oil barrel 301 for recovery through the oil discharge port of the oil pump cavity, the fourth oil guide hose 305a and the oil inlet straight pipe 305. Since the oil inlet straight pipe 305 is located at the bottom of the annular partition plate 303, the recovered oil will be filtered by the cylindrical filter 303a when it is drawn away again by the first oil guide hose 304a, ensuring that the oil entering the oil pump cavity is clean. The impurities blocked by the cylindrical filter 303a fall into the conical charging barrel 302 under the action of gravity when standing still and gather there.

[0019] In this embodiment, the clamping assembly 203 includes a fixed block 203a arranged at the end of the rotating shaft 202, and a clamping groove 203b is opened in the middle of the fixed block 203a along the length direction, and a bearing seat 203d is fixed in the middle of the clamping groove 203b through a support plate 203c, and a bidirectional screw rod 203e is fixed in the inner ring of the bearing seat 203d. Clamping blocks 203f are respectively slidably clamped on both sides of the inner side of the clamping groove 203b, and the two clamping blocks 203f are respectively threadedly connected to the bidirectional screw rod 203e. A clamping block 203g is provided on the top of the two clamping blocks 203f, and a handwheel 203e-1 is provided at one end of the bidirectional screw rod 203e, and a handle 203e-2 is provided on the handwheel 203e-1.

[0020] Place the oil pump in the middle of the fixed block 203a, and use the handle 203e-2 to shake the handwheel 203e-1 to drive the bidirectional screw rod 203e to rotate, driving the two clamping blocks 203f to approach each other until the clamping blocks 203g at the top of the two clamping blocks 203f clamp the oil pump.

[0021] In this embodiment, a top cover 301a is threadedly connected to the top opening of the oil cylinder 301, a handle 301b is provided on the top of the top cover 301a, a discharge pipe 302a is provided at the bottom of the conical loading barrel 302, and a butterfly valve 302b is provided on the discharge pipe 302a.

[0022] After the impurities and dirt brought out by the oil from the inner cavity of the oil pump are recovered in the oil barrel 301, the impurities and dirt sink into the conical charging barrel 302 under the action of gravity. When a large amount of impurities and dirt accumulate at the bottom of the conical charging barrel 302, the butterfly valve 302b can be opened to release the oil mixed with impurities and dirt at the bottom of the conical charging barrel 302. When the oil is too little, the top cover 301a can be unscrewed to add oil to the inside of the oil barrel 301.

[0023] In this embodiment, the inner wall of the shell 100 is provided with two clamping plates 106 inclined toward the bottom wall of the cleaning chamber 101, and the clamping plate 106 is provided with an L-shaped through hole 106a connected to the outside. One end of the third oil guiding hose 306a and the fourth oil guiding hose 305a pass through the shell 100 and enter the interior of the cleaning chamber 101. The outer walls of the ends of the third oil guiding hose 306a and the fourth oil guiding hose 305a are respectively provided with a conical rubber plug 307 with a hollow center. The width of the L-shaped through hole 106a is greater than the diameter of the third oil guiding hose 306a and the fourth oil guiding hose 305a, and the width of the L-shaped through hole 106a is smaller than the bottom diameter of the conical rubber plug 307.

[0024] The tapered rubber plug 307 can tightly connect the ends of the third oil guiding hose 306a and the fourth oil guiding hose 305a to the oil inlet and oil outlet of the oil pump to prevent them from falling off. After the inner cavity of the oil pump is cleaned, one end of the third oil guiding hose 306a and the fourth oil guiding hose 305a can be placed in the L-shaped through hole 106a. Since the width of the L-shaped through hole 106a is larger than the diameters of the third oil guiding hose 306a and the fourth oil guiding hose 305a, and the width of the L-shaped through hole 106a is smaller than the bottom diameter of the tapered rubber plug 307, the bottom of the tapered rubber plug 307 can overlap the top of the clamping plate 106, ensuring that the ends of the third oil guiding hose 306a and the fourth oil guiding hose 305a are facing upward, avoiding the oil inside the third oil guiding hose 306a and the fourth oil guiding hose 305a from flowing into the cleaning chamber 101 after each cleaning of the oil pump inner cavity, causing oil waste.

[0025] In this embodiment, a drain pipe 104 communicating with the cleaning chamber 101 is provided at the bottom of the outer wall of the shell 100 , a drain valve 104 a is provided on the drain pipe 104 , and supporting legs 105 are respectively provided at the corners of the bottom end of the shell 100 .

[0026] Working principle: Place the oil pump that needs to be cleaned in the middle of the fixed block 203a, and use the handle 203e-2 to shake the handwheel 203e-1 to drive the bidirectional screw rod 203e to rotate, and drive the two clamping blocks 203f to move closer to each other until the clamping blocks 203g at the top of the two clamping blocks 203f clamp the oil pump, and turn on the liquid pump 404. The liquid pump 404 pumps the clean water in the liquid storage tank 403 into the inner cavity of the spray block 401 through the first drain pipe 404a and the second drain pipe 404b in turn, and the multiple spray holes 401a evenly distributed on the end surface of the spray block 401 spray and rinse the surface of the oil pump casing, and turn on the rotating motor 201, which drives the rotating motor 201 through the rotating shaft 202 The oil pump rotates so that the oil pump housing can be fully sprayed and rinsed. After the oil pump housing is cleaned, turn off the rotating motor 201 and the liquid pump 404, connect the tapered rubber plug 307 at the end of the third oil guide hose 306a to the oil inlet of the oil pump, connect the tapered rubber plug 307 at the end of the fourth oil guide hose 305a to the oil discharge port of the oil pump, and start the oil pump 306. The oil pump 306 sends the clean oil filtered by the cylindrical filter 303a through the first oil guide hose 304a, the oil discharge straight pipe 304, the second oil guide hose 304b and the third oil guide hose 306a in sequence to the inner cavity of the oil pump for flushing and cleaning. The impurities and dirt in the inner cavity of the oil pump are mixed with the oil and discharged by the oil pump. The inner cavity oil drain port, the fourth oil guiding hose 305a and the oil inlet straight pipe 305 are discharged to the inside of the oil barrel 301 for recovery. Since the oil inlet straight pipe 305 is located at the bottom of the annular partition plate 303, the recovered oil will be filtered by the cylindrical filter 303a when it is drawn away by the first oil guiding hose 304a again, ensuring that the oil entering the oil pump cavity is clean. After the oil pump cavity is cleaned, one end of the third oil guiding hose 306a and the fourth oil guiding hose 305a can be placed in the L-shaped through hole 106a. Since the width of the L-shaped through hole 106a is larger than the diameter of the third oil guiding hose 306a and the fourth oil guiding hose 305a, and the width of the L-shaped through hole 106a is smaller than the width of the tapered rubber plug 30 7, so the bottom of the conical rubber plug 307 can be overlapped with the top of the clamping plate 106, ensuring that the ends of the third oil guiding hose 306a and the fourth oil guiding hose 305a are facing upward, preventing the oil inside the third oil guiding hose 306a and the fourth oil guiding hose 305a from flowing into the cleaning chamber 101 each time the inner cavity of the oil pump is cleaned, causing oil waste. The impurities blocked by the cylindrical filter 303a fall into the conical charging barrel 302 under the action of gravity when standing still and gather. When too many impurities gather, the butterfly valve 302b is opened to release the oil mixed with impurities and dirt at the bottom of the conical charging barrel 302. When the oil is too little, the top cover 301a can be unscrewed to add oil to the oil cylinder 301.

[0027] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. 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, and all of these should be included in the scope of the claims of the present invention.
