[0029] The cleaning assembly comprises a plurality of folding rods 21 and a plurality of cleaning rods 22 which are equal in number to the folding rods 21, the plurality of folding rods 21 are rotationally arranged at the end of the rotating column 17 away from the lifting platform 15, reset coil springs are arranged at the joint of the folding rods 21 and the rotating column 17, the plurality of folding rods 21 are evenly distributed in a ring shape, the cleaning rods 22 are rotationally arranged at the end of each folding rod 21 away from the rotating column 17, reset coil springs are arranged at the joint of the cleaning rods 22 and the folding rods 21, a brush is arranged on one side of each cleaning rod 22, a plurality of rollers 20 are rotationally arranged at the bottom of the constraint cylinder 19, the number of the rollers 20 is equal to the number of the folding rods 21, the rollers 20 block the folding rods 21 or the cleaning rods 22, an arc-shaped gap 23 is arranged at the position corresponding to the joint of each folding rod 21 of the rotating column 17, when the third electric push rod 18 continues to lift the constraint cylinder 19, the folding rods 21 are unfolded outward under the action of the reset coil springs, at this time, the brushes on the cleaning rods 22 face outward, the brushes realize the cleaning of the side surface of the tank body, during the outward turning of the folding rods 21, the depth of the arc-shaped gap 23 gradually deepens, the inner slide rod 24 slides along the arc-shaped gap 23 under the action of the tension spring 25, the locking block 26 is inserted into the locking groove, so that the folding rods 21 and the cleaning rods 22 are fixedly connected and cannot relatively rotate, even during the rotation, the cleaning rods 22 will not be deflected outward due to the centrifugal force, ensuring that the brushes on the cleaning rods 22 face outward, achieving the effect of cleaning the side surface of the tank body.

[0030] The inner slide of each folding rod 21 is provided with an inner slide rod 24, and a tension spring 25 is further arranged between the inner slide rod 24 and the inner part of the folding rod 21; the end of the inner slide rod 24 away from the cleaning rod 22 extends out of the folding rod 21, and the inner slide rod 24 is in sliding contact with the arc-shaped notch 23; the end of the inner slide rod 24 close to the cleaning rod 22 is provided with a locking block 26; the rotating shaft of each cleaning rod 22 is provided with a locking groove, and the locking block 26 is matched with the locking groove; after the inner wall and the bottom surface of the tank body are cleaned, the third electric push rod 18 pushes the constraint cylinder 19 downward, the folding rod 21 is first retracted, the inner slide rod 24 is squeezed into the folding rod 21 by the arc-shaped notch 23, the locking block 26 is away from the locking groove, and the cleaning rod 22 is retracted in sequence; the constraint cylinder 19 scrapes off the water stains adhered to the outer wall of the folding rod 21; when the cleaning rod 22 is folded into a cylindrical body with the same outer diameter as the rotating column 17, the concentrated brush can be conveniently washed by the operator, and the outer side of the cleaning rod 22 is also easy to clean; through the arrangement of the cleaning assembly, the folding rod 21 and the cleaning rod 22 after being opened can realize the cleaning of the inner wall and the bottom surface of the tank body, and the folding rod 21 and the cleaning rod 22 after being folded are easy to clean, thereby solving the technical problem that the cleaning equipment is difficult to clean.

[0031] The working principle of the present application is as follows: the operator pushes the cleaning equipment above the tank body to be cleaned, drives the moving module 3 to move on the guide rail 2 by using the control system, controls the first machine box 4 to rotate by the moving module 3, and simultaneously drives the lifting assembly and the cleaning assembly to enter the tank body to prepare for cleaning; the operator fixes the spray head to the moving module 3 by using the cable, sends water to the spray head through the water pipe, and sprays the water on the inner wall of the tank body through the spray head.

[0032] When the height of the lifting platform 15 needs to be controlled, the control system makes the first motor 7 electrified, the first motor 7 drives the worm 8 to rotate, the worm 8 drives the worm wheel 9 to rotate, the worm wheel 9 drives the driving gear 10 to rotate synchronously, the driving gear 10 drives the first driven gear 11 and the second driven gear 12 to rotate, because the meshing positions of the first driven gear 11 and the second driven gear 12 and the driving gear 10 are opposite, the first driven gear 11 and the second driven gear 12 rotate at the same speed and in the same direction, and then the first electric push rod 13 and the second electric push rod 14 are driven to swing by the fixed block, and the lifting platform 15 is driven to ascend and descend; under the drive of the first motor 7 and the first electric push rod 13 and the second electric push rod 14, the lifting platform 15 can be controlled to move to a suitable position, so that the cleaning assembly can clean the tank body.

[0033] The height between the two fixed blocks is the same as the height of the two adapter holes on the lifting platform 15. During the working process of the first electric push rod 13 and the second electric push rod 14, the control system controls them to extend or retract by the same distance at the same time, so that the axes of the first electric push rod 13 and the second electric push rod 14 always remain parallel. The square shaft 5, the first electric push rod 13, the second electric push rod 14 and the lifting platform 15 form a parallelogram mechanism. Regardless of how the first electric push rod 13 and the second electric push rod 14 swing, the lifting platform 15 always remains parallel to the bottom surface of the tank body.

[0034] When the third electric push rod 18 pushes the constraint cylinder 19 to the lowest position, the rollers 20 abut against the cleaning rods 22, and all the cleaning rods 22 are folded together to form a cylinder with the same outer diameter as the rotating column 17. When the third electric push rod 18 lifts the constraint cylinder 19, the rollers 20 abut against the folding rods 21, and the cleaning rods 22 lose the constraint of the constraint cylinder 19 and open outward under the action of the return coil spring until the cleaning rods 22 form a right angle with the folding rods 21, and the brushes on the cleaning rods 22 face the bottom. When the second motor 16 drives the rotating column 17 to rotate, the cleaning rods 22 begin to rotate, and the brushes achieve cleaning of the bottom surface of the tank body. The main motor drives the square shaft 5 to rotate, thereby expanding the cleaning range of the brushes of the cleaning rods 22.

[0035] When the third electric push rod 18 continues to lift the constraint cylinder 19, the folding rods 21 lose the constraint of the constraint cylinder 19 and open outward under the action of the return coil spring. At this time, the brushes on the cleaning rods 22 face outward, and the brushes achieve cleaning of the side surface of the tank body. During the outward turning process of the folding rods 21, the depth of the arc-shaped notch 23 gradually deepens, and the inner sliding rod 24 slides along the arc-shaped notch 23 under the action of the tension spring 25. The locking block 26 is inserted into the locking slot, so that the folding rods 21 and the cleaning rods 22 are fixedly connected and cannot rotate relative to each other. Even during the rotating process, the cleaning rods 22 will not be deflected outward due to the centrifugal force, ensuring that the brushes on the cleaning rods 22 face outward and achieving the effect of cleaning the side surface of the tank body.

[0036] After the inner wall and the bottom surface of the tank body are cleaned, the third electric push rod 18 pushes the constraint cylinder 19 downward. The folding rods 21 are retracted first, the inner sliding rod 24 is squeezed into the folding rods 21 by the arc-shaped notch 23, the locking block 26 leaves the locking slot, and the cleaning rods 22 are retracted in sequence. The constraint cylinder 19 scrapes off the water stains adhered to the outer wall of the folding rods 21. When the cleaning rods 22 are folded into a cylinder with the same outer diameter as the rotating column 17, it is convenient for the operator to flush the concentrated brushes. The outer side of the cleaning rods 22 is also easier to clean. Through the arrangement of the cleaning assembly, the folding rods 21 and the cleaning rods 22 after being opened can clean the inner wall and the bottom surface of the tank body, and the folding rods 21 and the cleaning rods 22 after being folded are easier to clean, thereby solving the technical problem that the cleaning equipment is difficult to clean.

[0037] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics of the present application. The embodiments should therefore be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No reference signs in the claims should be considered as limiting the scope of the claims with respect to the figures of the patent document.
