A rectangular bracket groove 634 and a seesaw groove 633 are also provided in the support shell 63. The H-shaped support frame 64 is fixed in the rectangular bracket groove 634. The rectangular bracket groove 634 has the same size as the H-shaped support frame 64. Specifically, the vertical bars at both ends of the H-shaped support frame 64 are fixed on the front and rear end inner walls of the rectangular bracket groove 634, and the middle of the H-shaped support frame 64 is a cylindrical cross bar; the seesaw 65 is arranged in the seesaw groove 633, and the middle part of the seesaw 65 is rotatably connected to the cross bar of the H-shaped support frame 64. Specifically, a through hole is opened in the middle part of the seesaw 65, and the seesaw 65 is movably sleeved on the cross bar in the middle of the H-shaped support frame 64 through the through hole, and is rotatably connected to the cross bar. The width of the seesaw groove 633 is equal to the width of the seesaw 65, and the length and height of the seesaw groove 633 are both larger than the seesaw 65, so that the seesaw 65 can rotate vertically in the seesaw groove 633.

[0045] In this embodiment, the first movable rod 66 and the second movable rod 67 are movably provided in the first roller frame 611 and the two second roller frames 621 respectively. Specifically, the first movable rod 66 passes through the through holes at the lower ends of the two fixed blocks of the first roller frame 611 in sequence and is rotatably connected to the first roller frame 611.

[0046] In this embodiment, the two ends of the seesaw 65 are movably mounted on the first movable rod 66 and the second movable rod 67. Preferably, through grooves are provided at both ends of the seesaw 65, and the front ends of the first movable rod 66 and the second movable rod 67 pass through the through grooves at both ends and extend toward the inner wall of the support shell 63; a Z-shaped through groove 635 is provided on the side wall of the support shell 63, and the front end of the first movable rod 66 passes through the Z-shaped through groove 635 and extends to the outside of the Z-shaped through groove 635, and the front end head thereof is slidably connected to the limited block 661. For details, refer to Figure 5 The limit block 661 is a rectangular tube structure with a certain thickness. The inner wall height of the limit block 661 is the same as the diameter of the first movable rod 66, so that the limit block 661 can move and rotate on the first movable rod. When in use, the limit block 661 drives the first movable rod 66 to move up and down in the Z-shaped groove, so that the first support roller 61 and the second support roller 62 can be adjusted to alternately provide support for the rotating rod 3, so as to avoid the movement direction of the rotating rod 3 being inconsistent with the rotation direction of the support roller, causing damage to the rotating rod 3 or the support roller. After adjusting the vertical displacement, the limit block 661 can be inserted into the upper or lower end of the Z-shaped groove, so as to fix the vertical position of the first movable rod 66. The two ends of the outer side wall of the limit block 661 are also fixed with protruding blocks for facilitating the insertion and removal of the limit block 661.

[0047] The principle of alternating support of the first support roller 61 and the second support roller 62 of the present embodiment is as follows: the seesaw 65 is fixed by the H-shaped support frame 64, forming a structure in which its left and right ends rotate with the cross bar of the H-shaped support frame 64 as the midpoint. When the rotating rod 3 needs to move forward and backward, the limit block 661 is moved to the uppermost end of the Z-shaped through groove 635, and the limit block 661 is pushed backward and inserted into the upper end cross groove of the Z-shaped through groove 635. When the limit block 661 drives the first movable rod 66 to move upward, it drives the seesaw 65 to rotate clockwise. At this time, the left end of the seesaw 65 is upward and the right end is downward. The first movable rod 66 drives the first roller frame 611 and the first support roller 61 to move upward, and the second movable rod 67 drives the second roller frame 621 and the second support roller 62 to move downward. 61 provides support for the rotating rod 3, and the second supporting roller 62 is hidden in the second roller groove 632; when the rotating rod 3 needs to rotate, the limit block 661 is pulled out from the uppermost end of the Z-shaped through groove 635 and moved to the lowermost end of the Z-shaped through groove 635, and the limit block 661 is pushed backward and inserted into the lower end transverse groove of the Z-shaped through groove 635. When the limit block 661 drives the first movable rod 66 to move downward, it drives the seesaw 65 to rotate counterclockwise. At this time, the left end of the seesaw 65 is downward and the right end is upward. The first movable rod 66 drives the first roller frame 611 and the first supporting roller 61 to move downward, and the second movable rod 67 drives the second roller frame 621 and the second supporting roller 62 to move upward. The second supporting roller 62 provides support for the rotating rod 3, and the first supporting roller 61 is hidden in the first roller groove 631. Through the above structure and principle, the first supporting roller 61 and the second supporting roller 62 alternately provide support for the rotating rod 3.

[0048] In this embodiment, a transmission assembly 68 is also provided in the support shell 63, and the transmission assembly includes a transmission rod 681 and a spring 682. One end of the spring 682 is fixed to the lower end of the transmission rod, and the other end is fixed to the support shell. The upper end of the transmission rod 681 is an arc-shaped surface that fits the rotating rod 3. The transmission rod 681 and the first support roller 61 and the two second support rollers 62 alternately support the rotating rod 3. As an embodiment, the transmission rod 681 includes a vertical rod, a longitudinal horizontal rod and a transverse horizontal rod. The top surface of the vertical rod is an arc-shaped surface that fits the rotating rod 3. The vertical rod is connected to the rear end of the longitudinal horizontal rod, and the front end of the longitudinal horizontal rod is connected to the left end of the transverse horizontal rod. A first vertical rod extending to the upper end of the Z-shaped through groove 635 is fixed to the middle upper side of the transverse horizontal rod. A second vertical rod is fixed to the right end of the transverse horizontal rod. The upper end of the second vertical rod extends toward the inside of the lower end of the Z-shaped through groove 635. The lower end of the second vertical rod extends downward and is fixed to one end of a spring 682. The other end of the spring 682 is fixed to a supporting shell below the second vertical rod. A cavity for accommodating the transmission assembly 68 is provided in the side wall of the supporting shell and in the supporting shell. Figure 6 and Figure 7The transmission assembly 68 can move vertically in the cavity, and the upper ends of the first vertical rod and the second vertical rod of the transmission rod 681 extend into the Z-shaped through groove 635. When the limit block 661 is inserted into the Z-shaped through groove, the first vertical rod or the second vertical rod receives the extrusion force and moves downward, driving the vertical rod, the longitudinal horizontal rod and the transverse horizontal rod to move downward, so that the upper surface of the vertical rod is separated from the rotating rod 3. At this time, the spring 682 at the lower end of the second vertical rod is compressed; when the limit block 661 is pulled out of the Z-shaped through groove 635, the extrusion force on the upper end of the first vertical rod or the second vertical rod disappears, the spring 682 is not subjected to force, and the elastic force is restored, thereby driving the vertical rod, the longitudinal horizontal rod and the transverse horizontal rod to move upward, so that the upper surface of the vertical rod extends out of the supporting shell 63 to provide support for the rotating rod 3. Through the above structure, during the support conversion process between the first support roller 61 and the two second support rollers 62, the transmission rod 681 provides support for the rotating rod 3, so as to avoid the rotating rod losing its supporting force during the support conversion process, thereby causing damage to the rotating rod 3 or the driving device 4.

[0049] When the device is in use, the universal wheel 5 under the mobile platform 7 is used to move the device to the front of the pipe to be cleaned, and the center line of the rotating rod 3 is aligned with the center line of the pipe as much as possible; the limit block 661 is moved upward and the limit block 661 is inserted into the transverse groove at the upper end of the Z-shaped through groove 635 and fixed, so that the first support roller 61 protrudes from the upper surface of the support shell 63, and the knob 74 is turned clockwise to move the first sliding block 72 forward on the first screw rod 73, driving the driving device 4 and the rotating rod 3 to move forward. The first support roller 61 rotates under the action of the rotating rod 3 and provides support for the rotating rod 3 until the blade 1 and the cleaning brush 21 enter the pipe, and the knob 74 is stopped; the second drive motor 42 is controlled to start, and the distance between the cleaning brush 21 and the rotating rod 3 is adjusted so that the outermost side wall of the cleaning brush 21 Contact with the inner wall of the pipeline, control the second drive motor 42 to stop; pull out the limit block 661 from the Z-shaped through groove 635 and move it down to the lower end of the Z-shaped through groove 635, insert the limit block 661 into the horizontal groove at the lower end and fix it, and the two second support rollers 62 protrude from the upper surface of the support shell 63; control the first drive motor 44 to start, the rotating rod 3 rotates under the drive of the first drive motor 44, the blade 1 in front of the rotating rod 3 cuts the garbage in the pipeline, and the cleaning brush 21 sweeps the debris on the inner wall of the pipeline, and the second support roller 62 rotates under the action of the rotating rod 3. The two second support rollers 62 rotate in the opposite direction to the rotating rod 3 and provide support for the rotating rod 3. By adjusting the first support roller 61 and the second support roller 62 to support alternately, it can adapt to the two different states of movement and rotation of the rotating rod 3 and provide support for the rotating rod 3. The front end of the rotating rod 3 is conical, which can break the garbage blockage in the pipeline and further improve the cleaning efficiency. In different application scenarios, the rotation mode of the rotating rod 3 can also be changed, such as alternating between forward and reverse rotations, to improve the efficiency and effect of pipeline cleaning.
