[0033] Reference below Figures 1 to 3 A cleaning system according to an embodiment of the present invention is described.

[0034] like Figures 1 to 3 As shown, the cleaning system according to an embodiment of the present invention includes:

[0035] A plurality of cleaning heads 100 for cleaning the inner wall of the casing;

[0036] The shaft 200 has two connecting seats 210 spaced apart thereon, and the shaft 200 has a supporting spring 700 disposed thereon for pushing the two connecting seats 210 to move relative to each other, and the driving device 800 is in transmission connection with the shaft 200 to drive the shaft 200 to rotate;

[0037] A plurality of lifting platforms 300 are provided, and the lifting platforms 300 include two connecting rod mechanisms, and the two connecting rod mechanisms include a first connecting rod 310 and a second connecting rod 320. The opposite ends of the first connecting rod 310 and the second connecting rod 320 are hingedly connected, and the top ends of the two first connecting rods 310 are connected to the cleaning head 100, and the bottom ends of the two second connecting rods 320 are respectively hingedly connected to a connecting seat 210, and a third connecting rod 330 is provided between the two second connecting rods 320, and the two ends of the third connecting rod 330 are respectively rotatably connected to the two second connecting rods 320.

[0038] When the cleaning system of the present application is cleaning a cable sheath with a variable diameter, as the cleaning system moves forward along the cleaning direction of the sheath, the driving device 800 drives the shaft 200 to rotate, so that the cleaning system continuously rotates and moves forward to clean the entire inner wall. As the cleaning system continuously moves forward and the pipe diameter continuously changes, the support spring 700 will automatically expand and contract and adjust. Through the tension force provided by the support spring 700, the cleaning head 100 always keeps in contact with the inner wall of the sheath, thereby completing the cleaning of the inner wall of the sheath with a changing inner diameter.

[0039] Specifically, when the cleaning system cleans along the direction in which the diameter of the sleeve is continuously reduced, as the diameter of the sleeve is continuously reduced, the height of the lifting platform 300 needs to be lowered and adjusted accordingly, and at this time, the two connecting seats 210 move in opposite directions, and the compression support spring 700 contracts. As the two connecting seats 210 gradually move away from each other, the distance between the bottom ends of the two second connecting rods 320 increases continuously, and the two second connecting rods 320 rotate around the third connecting rod 330, and the distance between the top ends of the two second connecting rods 320 increases, and the distance between the lower ends of the first connecting rod 310 increases accordingly, and rotates around the connection position with the cleaning head 100, and finally the first connecting rod 310 and the second connecting rod 320 are transformed from a straight state to a bent state, and the overall height of the lifting platform 300 gradually decreases.

[0040] When the cleaning system cleans along the direction in which the diameter of the casing pipe continues to increase, as the diameter of the pipe continues to increase, the height of the lifting platform 300 needs to be raised and adjusted accordingly.

[0041] At this time, as the inner diameter of the sleeve increases, the pressure of the cleaning head 100 from the tube wall decreases, the force on the support spring 700 decreases, and it begins to stretch, pushing the two connecting seats 210 to move toward each other. As the two connecting seats 210 gradually approach, the distance between the bottom ends of the two second connecting rods 320 continues to decrease, the two second connecting rods 320 rotate around the third connecting rod 330, the distance between the top ends of the two second connecting rods 320 decreases, and the distance between the lower ends of the first connecting rod 310 decreases accordingly, and rotates around the connection position with the cleaning head 100, finally making the first connecting rod 310 and the second connecting rod 320 change from a bent state to a straight state, and the overall height of the lifting platform 300 gradually increases.

[0042] By providing the support spring 700, the squeezing force from the tube wall on the cleaning head 100 and the elastic force of the support spring 700 are always in a balanced state, so that the cleaning head 100 always keeps in contact with the inner wall of the sleeve, thereby completing the cleaning work of the inner wall of the sleeve with a changing inner diameter.

[0043] In some embodiments of the present invention, a support platform 900 is provided at both ends of the shaft 200 , and the two connecting seats 210 are slidably mounted on the shaft 200 . Support springs 700 are provided between the two support platforms 900 and the corresponding connecting seats 210 .

[0044] In this embodiment, the two connecting seats 210 are both slidably mounted on the shaft 200 . During the cleaning process, the two connecting seats 210 can move relative to each other under the action of the corresponding supporting springs 700 .

[0045] In some embodiments of the present invention, one of the two connecting seats 210 is fixedly connected to the shaft 200, and the other is slidably mounted on the shaft 200. A support platform 900 is provided at one end of the connecting seat 210 corresponding to the sliding sleeve on the shaft 200, and a support spring 700 is provided between the support platform 900 and the slidably mounted connecting seat 210.

[0046] In this embodiment, one connecting seat 210 is fixedly connected to the shaft 200 and cannot move, while the other is slidably mounted on the shaft 200 and can move on the shaft 200 under the action of the supporting spring 700.

[0047] In some embodiments of the present invention, the cleaning head 100 includes a base 110 and a mounting seat 120, the base 110 includes a bottom plate 111 and two ends of the bottom plate 111 are provided with fixed mounting plates 112 extending upward, the mounting seat 120 is in the shape of a cylindrical drum, and the arc surface of the mounting seat 120 is covered with a cleaning towel 121, and the cleaning towel 121 is fixed to the mounting seat 120 by a fixing member 400.

[0048] When cleaning the inner wall of the sleeve, the cleaning system moves along the pipeline direction with the relevant driving device, and cleans the pipe wall as the driving device 800 rotates and moves forward, and the cleaning head 100 always keeps in contact with the pipe wall. During the cleaning process, the cylindrical mounting seat 120 will rotate continuously, and the cleaning towel 121 covering the cylindrical pipe wall will continuously wipe the pipe wall. Because the mounting seat 120 rotates continuously, the entire surface of the cleaning towel 121 is used, which improves the cleaning efficiency of the cleaning towel 121. After using for a period of time, the cleaning towel 121 can be removed from the mounting seat 120 and replaced with a new cleaning towel 121 to ensure the cleaning quality.

[0049] like Figure 2 and Figure 3As shown, in a further embodiment of the present invention, the mounting seat 120 is in the shape of a semicircular drum, the arc surface of the mounting seat 120 faces outward, a connecting ear 122 is provided on the bottom plane of the mounting seat 120, and the fixing member 400 includes two fixing plates, which are respectively arranged on both sides of the arc surface of the mounting seat 120, one side of the fixing plate is pressed on the cleaning towel 121, and the fixing plate is fixed by being connected to the connecting ear 122, and a limiting mechanism is provided between the mounting seat 120 and the base 110 to limit the rotation range of the mounting seat 120.

[0050] In this embodiment, the mounting seat 120 is in the shape of a semicircular drum, so that the cleaning towel 121 is easily fixed on the mounting seat 120. Specifically, when the cleaning towel 121 is fixed on the mounting seat 120, the cleaning towel 121 is first laid on the mounting seat 120, and the two sides are pressed by two fixing plates, and then the two fixing plates are connected and fixed with the connecting ears 122, so that the cleaning towel 121 is tightly pressed on the mounting seat 120. When replacing, the fixing plates and the connecting ears 122 are loosened, and a new cleaning towel is replaced.

[0051] At the same time, in order to prevent the mounting seat 120 from rotating to the non-cleaned surface contacting the tube wall during the cleaning process, a limit mechanism is provided to limit the rotation range of the mounting seat 120 to ensure that the cleaned surface of the mounting seat 120 contacts the inner wall of the sleeve.

[0052] Because of the existence of the limiting mechanism of the mounting seat 120, the mounting seat 120 cannot continue to rotate after rotating to a certain angle. Therefore, only the side of the cleaning towel 121 arranged on the mounting seat 120 that contacts the tube wall is used, while the side of the cleaning towel 121 that does not contact the tube wall is not used.

[0053] After the sleeve completes a cleaning process, the cleaning system moves in the reverse direction in the sleeve along with the walking device to perform a second cleaning on the sleeve, thereby improving the cleaning effect. At the same time, the motor reverses and the mounting seat 120 rotates. After rotating to a certain angle, it stops rotating under the action of the limiting mechanism, so that the cleaning towel 121 on the unused side can be reused, thereby improving the use efficiency of the cleaning towel 121.

[0054] In the present invention, the limit mechanism limits the rotation range of the mounting seat 120 to between -37° and 37°. This design is adapted to the diameter of the cable sleeves currently used. The use range of the mounting seat 120 when it is rotated to one side is exactly 0° to 37°, and the use range of the mounting seat 120 when it is rotated to the other side is -37° to 0°. In this way, the entire cleaning surface of the cleaning towel 121 is fully utilized.

[0055] In a further embodiment of the present invention, the limiting mechanism includes a limiting groove 510 and two angle limiting blocks 520. The limiting groove 510 is horizontally arranged on the bottom plane of the mounting seat 120. The two angle limiting blocks 520 are fixedly connected to the base 110 and are located on the rotation path of the limiting groove 510 to limit the rotation range of the mounting seat 120.

[0056] like Figure 3 As shown, when the mounting seat 120 rotates to a certain angle, the limiting groove 510 rotates to contact with the angle limiting block 520 on one side, and the mounting seat 120 cannot continue to rotate. When the mounting seat 120 rotates to the other side, the limiting groove 510 rotates to contact with the angle limiting block 520 on the other side, and the mounting seat 120 cannot continue to rotate. By providing the limiting groove 510 and the two angle limiting blocks 520, the rotation range of the mounting seat 120 is limited to between the two angle limiting blocks 520, so that the cleaning towel 121 on the mounting seat 120 is always kept in contact with the pipe wall.

[0057] In some embodiments of the present invention, guide wheels 600 are disposed on both fixed mounting plates 112 , and the height difference between the upper end of the guide wheel 600 and the upper end of the cleaning towel 121 is smaller than the compression limit of the cleaning towel 121 .

[0058] When the cleaning head 100 cleans the sleeve, the cleaning towel 121 will fit with the sleeve. However, if the fitting force is too large, the friction between the cleaning towel 121 and the inner wall of the sleeve will be too large, resulting in poor cleaning effect and serious wear of the cleaning towel 121. Guide wheels 600 are arranged on the outer sides of the two fixed mounting plates 112. After the cleaning towel 121 is deformed to a certain extent, the guide wheels 600 will contact with the inner wall of the sleeve, preventing the cleaning towel 121 from further deforming under pressure, so that the cleaning towel 121 is subjected to appropriate extrusion force, and the fitting force between the cleaning towel 121 and the sleeve is relatively appropriate.

[0059] At the same time, during the wiping process, there is rolling friction between the guide wheel 600 and the inner wall of the sleeve, and the friction force is small, which will not cause adverse effects on the cleaning process.

[0060] The height difference between the upper end of the guide wheel 600 and the upper end of the cleaning towel 121 depends on the compression limit of the cleaning towel 121 that can be deformed under pressure. Note that the compression limit mentioned here does not refer to the compression limit that the cleaning towel 121 itself can withstand, but refers to the allowable standard compression limit. This height difference is determined based on actual conditions, thereby determining the installation position of the guide wheel 600.

[0061] In some embodiments of the present invention, a fourth connecting rod 340 is provided between the two first connecting rods 310, and both ends of the fourth connecting rod 340 are rotatably connected to the two first connecting rods 310. By providing the fourth connecting rod 340, the structural strength between the two first connecting rods 310 is improved, and the correlation between the two is improved, so that the deformation can be maintained synchronously.

[0062] In some embodiments of the present invention, the base 110 includes two parallel mounting rods, the two mounting rods are arranged in parallel, the two ends of the mounting rods are respectively connected to the two fixed mounting plates 112, and the upper ends of the two first connecting rods 310 are respectively hinged to one mounting rod.

[0063] In some embodiments of the present invention, the driving device 800 is a motor, and the motor and the shaft are connected via a coupling.
