Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] like Figures 1 to 7 As shown, the present invention provides an all-round cleaning device for an engine cylinder body, which includes a cylinder body 1 and a cylinder hole 2 opened on the cylinder body 1, the cylinder body 1 is located in a cleaning chamber 3, and evenly distributed high-pressure nozzles 4 are provided on the left and right chamber walls and the top wall of the inner front half of the cleaning chamber 3. The high-pressure nozzles 4 can be used to comprehensively spray the outer surface of the cylinder body 1, thereby ensuring that impurities on the outer surface of the cylinder body 1 are removed.

[0030] A water supply tank 5 is provided above the top of the cleaning chamber 3. The high-pressure nozzle and the water tank are connected by a water supply pipe 6. The water supply tank 5 is provided with a water pump. The water pump will pump out the water in the water supply tank 5, and then transport the water to the high-pressure nozzle 1 4, the high-pressure nozzle 2 12, and the high-pressure nozzle 3 30 through the water supply pipe 6, so as to comprehensively clean the cylinder body 1.

[0031] A dynamic fixed-point component is provided at the bottom end of the bottom cleaning bin 3, and the cylinder body 1 is placed on the dynamic fixed-point component. A top fixed-point cleaning component is provided on the left and right walls of the rear half of the interior of the cleaning bin 3. When the dynamic fixed-point component moves the cylinder body 1 to the rear half of the cleaning bin 3, the fixed-point cleaning component positions and cleans the cylinder hole 2.

[0032] One side of the cleaning chamber 3 is open, and a movably connected revolving door 7 is provided at the opening of the cleaning chamber 3 . The revolving door 7 can be placed into the cleaning chamber 3 with the cylinder body 1 , and a handle 8 is provided on the outer wall of the revolving door 7 .

[0033] A through leakage hole 9 is provided on the bottom plate of the cleaning chamber 3. The leakage hole 9 allows the sprayed water to flow out through the leakage hole 9, and the water can be filtered in subsequent processing.

[0034] Inclined landslides 10 are provided on both sides of the water leakage hole 9, and the inclined landslides 10 can make water flow into the water leakage hole 9 and flow out better.

[0035] The rear half of the cleaning chamber 3 is located in the leakage hole 9 and is provided with a vertical rising column 11. The interior of the rising column 11 is hollow, and a high-pressure nozzle 12 is provided on the top of the rising column 11. A water supply pipe 6 is connected between the rising column 11 and the water supply box 5. The rising column 11 is movably connected in the leakage hole 9, so that when the cylinder body 1 enters the rear half of the cleaning chamber 3, the rising column 11 can extend to the interior of the cylinder body 1, and the interior of the cylinder body 1 is cleaned by the high-pressure nozzle.

[0036] A connecting plate 13 is provided at the bottom of the rising column 11, and a cylinder 14 is provided at the bottom end of the bottom plate of the cleaning chamber 3. The telescopic end of the cylinder 14 is connected to the connecting plate 13, thereby realizing automatic control of the rising column 11. When the cylinder body 1 moves, the cylinder drives the rising column 11 to descend to the bottom, so that the rising column 11 will not interfere with the movement of the cylinder body 1.

[0037] The dynamic fixed-point assembly includes a limit plate 15, a supporting plate 16, a positioning wheel 17 and a fixed-point plate 18. The limit plate 15 is symmetrically arranged on the inner bottom wall of the cleaning chamber 3, and the limit plate 15 is located on both sides of the leakage hole 9. The top of the limit plate 15 is symmetrically provided with a restraining groove 19. Through the limiting of the limit plate 15, the cylinder body 1 is placed and the movement of the fixed track is realized.

[0038] A supporting plate 16 is provided above the limit plate 15, a positioning wheel 17 is provided between the supporting plate 16 and the limit plate 15, the positioning wheel 17 is located in the restraining groove 19, an anti-skid plate 20 is provided on the top of the supporting plate 16, the cylinder body 1 is placed on the anti-skid plate 20, the anti-skid plate 20 and the supporting plate 16 are fixedly connected, which effectively prevents the cylinder body 1 from shifting during movement.

[0039] Furthermore, the lengths of the supporting plate 16 and the anti-slip plate 20 are smaller than the length of the cylinder body 1 , so that when the cylinder body 1 is finally transported to the position of the second fixed point plate 24 , the cylinder body 1 can fit on the second fixed point plate 24 .

[0040] A fixed point plate 18 is provided between the two anti-slip plates 20 and is attached to the side wall of the cylinder body 1 to achieve a preliminary fixation of the cylinder body 1.

[0041] The dynamic fixed-point assembly also includes a positioning rack 21, a rotating gear 22, a motor 23 and a fixed-point plate 24. The positioning rack 21 is fixed to the side of the supporting plate 16 close to the wall of the cleaning chamber 3. The rotating gear 22 cooperates with the positioning rack 21. The motor 23 with an external power supply is on the left and right side walls of the cleaning chamber 3. The output shaft of the motor 23 is connected to the rotating gear 22. Through the cooperation of the rotating gear 22 and the positioning rack 21, the cylinder body 1 can achieve automatic displacement.

[0042] A second fixed plate 24 is provided between the top of the other end of the travel limit plate 15 , and the cylinder body 1 can be fixed by the second fixed plate 24 and the first fixed plate 18 , thereby ensuring that the positioning cleaning component can clean the cylinder hole 2 .

[0043] The fixed-point cleaning component includes an extension rod 25, a connecting rod 26 and a movable plate 27. The connecting rod 26 passes through the wall of the cleaning bin 3. The interior of the connecting rod 26 is hollow. One end of the connecting rod 26 is connected to a water supply pipe 6. The connecting rod 26 extends into the interior of the cleaning bin 3 and is connected to the extension rod 25. The position of the extension rod 25 corresponds one-to-one to the position of the cylinder hole 2 on the cylinder body 1. A movable plate 27 is provided on the outside of the cleaning bin 3. The movable plate 27 is connected to the connecting rod 26. The movable plate 27 is driven to move by the provided cylinder 28, so that the extension rod plate can enter the cylinder hole 2 of the cylinder body 1 to clean the cylinder hole 2 on the cylinder body 1.

[0044] The fixed-point cleaning component also includes a cylinder 28, a cleaning brush head 29, and a high-pressure nozzle 30. The cylinder 28 is arranged on the inner wall of the cleaning chamber 3. The telescopic rod of the cylinder 28 passes through the wall of the cleaning chamber 3 and is connected to the movable plate 27. The cleaning brush head 29 and the high-pressure nozzle 3 30 are distributed in a ring shape on the outer wall of the extension rod 25, and the cleaning brush head 29 and the high-pressure nozzle 3 30 are distributed at intervals and staggered on the extension plate. The set cleaning brush head 29 and the high-pressure nozzle 3 30 can perform all-round cleaning of the cylinder hole 2, thereby avoiding the situation where the cylinder hole 2 is difficult to clean during the cleaning process of the cylinder body 1.

[0045] When the second cylinder 28 does not drive the extension rods 25 on both sides to approach each other, the distance between the extension rods 25 on both sides is greater than the width of the cylinder body 1, so that the cylinder body 1 can pass through the extension rods 25 during being moved to the second fixed plate 24 without being blocked.

[0046] Detailed usage and effects of the above embodiments:

[0047] When it is necessary to clean the cylinder body 1, first turn the cylinder body 1 upside down inside the cleaning bin 3 so that the opening of the cylinder body 1 faces downward, place the cylinder body 1 on the anti-slip plate 20, close the rotating door 7, and at this time, start the water pump, which will transport the water in the water supply tank 5 through the water supply pipe 6 and spray it through the high-pressure nozzle 1 4, the high-pressure nozzle 2 12, and the high-pressure nozzle 3 30. The high-pressure nozzle 1 4 is located in the front half of the cleaning bin 3 and is arranged on the left and right side walls and the top wall, so as to spray the outer surface of the cylinder body 1. At this time, start the motor 23, and the output shaft of the motor 23 is connected to the rotating gear 22, and the rotating gear 22 rotates to cooperate with the positioning rack 21.

[0048] The positioning rack 21 is displaced, so that the positioning wheel 17 connected to the supporting plate 16 can move in the restraining groove 19, thereby realizing the movement of the cylinder body 1 under the limit of the limit plate 15, and realizing the movement and cleaning of the outer surface of the cylinder body 1. When the positioning rack 21 is completely moved, the positioning rack 21 no longer moves. At this time, the side wall of the cylinder body 1 is just in contact with the positioning plate 2, and the cylinder body 1 is fixed by the positioning plate 1 and the positioning plate 2.

[0049] Cylinder 14 is started, and the telescopic rod of cylinder 14 is connected to the connecting plate 13, so that the connecting plate 13 rises, and the rising column 11 will enter the interior of the cylinder body 1, and the water sprayed by the high-pressure nozzle 2 12 will clean the interior of the cylinder body 1. Cylinder 3 will also be started at the same time, so that the movable plate 27 outside the cleaning chamber 3 moves toward the cleaning chamber 3, driving the connecting rod 26 to move, and the extension rod at the end of the connecting rod 26 will just enter the cylinder hole 2, and the cleaning brush head 29 on the outer wall of the extension rod and the high-pressure nozzle 3 30 will clean the inner wall of the cylinder hole 2, thereby achieving all-round cleaning of the cylinder body 1.

[0050] The cleaned water will flow into the leakage hole 9 through the inclined landslide 10. When the cylinder body 1 is cleaned, the extension rod 25 is separated from the cylinder hole 2, and the cylinder 14 drives the rising column 11 to descend, and the cylinder body 1 is moved to the initial position again, completing the entire cleaning process of the cylinder body 1.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
