It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. Hereinafter, the present invention will be described in detail with reference to the drawings and in combination with the embodiments.

[0021] See Figures 1 to 3 , which shows the preferred structure of the electrical wire conduit clogging clearing device provided by the embodiment of the present invention. As shown in the figure, the electrical wire conduit clogging clearing device includes: a rotary grinding mechanism 1, a rotary driving mechanism 2, a protective cover 3, and an inner support fixing mechanism 4; wherein,

[0022] The rotary driving mechanism 2 is arranged inside the protective cover 3, and the rotary driving mechanism 2 is connected to the rotary grinding mechanism 1 through a telescopic mechanism 6. The rotary driving mechanism 2 is used to drive the rotary grinding mechanism 1 to rotate so that the rotary grinding mechanism 1 grinds the fault point 51 of the to-be-treated wire conduit 5. The telescopic mechanism 6 is used to drive the rotary grinding mechanism 1 to retract into the protective cover 3 or extend out of the protective cover 3 to grind the fault point 51. Specifically, both ends of the telescopic mechanism 6 (such as Figure 2 the left and right ends shown) are respectively connected to the rotary grinding mechanism 1 and the rotary driving mechanism 2 to adjust the position of the rotary grinding mechanism 1, so that the rotary grinding mechanism 1 retracts into the protective cover 3 when moving forward along the to-be-treated wire conduit 5, thereby avoiding damaging the to-be-treated wire conduit 5 when the rotary grinding mechanism 1 moves forward; and it can extend out of the protective cover 3 during grinding, and then grind the fault point 51 by rotation so that the fault point 51 is ground and broken, thereby realizing the clearing of the fault point 51. Among them, the rotary grinding mechanism 1 can be a rotary grinding head with a tip structure at the head (such as Figure 2 the left end shown), the rotary driving mechanism 2 can be a driving motor, which is used to drive the rotary grinding mechanism 1 to rotate; the telescopic mechanism 6 can be a telescopic rod structure, which is connected with a telescopic driving mechanism (not shown in the figure) to drive the telescopic mechanism 6 to expand and contract, so that the telescopic mechanism 6 drives the rotary grinding mechanism 1 to extend out of the protective cover 3 or retract into the protective cover 3; of course, among them, the telescopic mechanism 6 can also be a linear servo electric cylinder to automatically realize expansion and contraction. The protective cover 3 can be a hollow shell with at least one end open, and its left end is at least open, so that the rotary grinding mechanism 1 can move from the left end of the protective cover 3, and the protective cover 3 and the rotary driving mechanism 2 are fixedly connected to ensure the stability of the rotary driving mechanism 2.

[0023] An inner support fixing mechanism 4 is provided on the outer wall of the protective cover 3, which is used to press against the inner wall of the pipeline 5 to be processed from the inside of the pipeline 5 to be processed, so as to fix the protective cover 3 to the pipeline 5 to be processed, thereby avoiding the movement of the electrical pipeline clogging clearing device during grinding. Specifically, the inner support fixing mechanism 4 can press against the inner wall of the pipeline 5 to be processed from the inside of the pipeline 5 to be processed, so as to realize the relative fixation between the pipeline 5 to be processed and the inner support fixing mechanism 4, and then realize the relative fixation between the pipeline 5 to be processed and the protective cover 3, that is, realize the relative fixation between the rotation driving mechanism 2 and the pipeline 5 to be processed.

[0024] The rotation driving mechanism 2 is connected to a cable 7; and, the middle of the cable 7 is wound in a cable reel 8, and the cable reel 8 is used to adjust the extended length of the cable 7. Specifically, the cable reel 8 can be an automatic cable reel, so as to release the cable 7 when the rotation driving mechanism 2 moves forward along the pipeline 5 to be processed, and after the rotation driving mechanism 2 is removed from the pipeline 5 to be processed, the excess cable 7 can be automatically collected and wound in the cable reel 8, thereby avoiding the problem of the cable 7 being randomly stacked at the construction site, and at the same time avoiding potential safety hazards during construction and power use. The power supply can be fixed on the cable reel 8 or at other positions, and no specific limitation is made in this embodiment. Among them, the cable 7 can be a rigid cable, which is used to support the rotation driving mechanism 2, so that the cable 7 not only serves as a cable, but also serves as a support rod structure to support the rotation driving mechanism 2, so as to hold the cable 7 and send it into the pipeline 5 to be processed from the pipe orifice of the pipeline 5 to be processed, and deliver the cable 7 into the pipeline 5 to be processed, so that the rotation driving mechanism 2 moves forward along the pipeline 5 to be processed until the rotation driving mechanism 2 cannot move forward, that is, it reaches the fault point 51. Among them, the rotation driving mechanism 2 is a small motor, so the weights of related components such as the grinding mechanism 1, the rotation driving mechanism 2, the protective cover 3, and the inner support fixing mechanism 4 extending into the pipeline 5 to be processed are relatively small, so the cable 7 can be used as its support to realize the feeding of related components in the pipeline 5 to be processed, and moreover, the cable 7 can also be wound in the cable reel 8.

[0025] In this embodiment, the rotation driving mechanism 2 is electrically connected to a controller 9 for controlling the operation of the rotation driving mechanism 2. Specifically, when the rotation driving mechanism 2 moves forward along the pipeline 5 to be processed until it can no longer move forward, that is, when it reaches the fault point 51, the operation of the rotation driving mechanism 2 is controlled by the controller 9, so that the rotation driving mechanism 2 drives the grinding mechanism 1 to rotate, thereby realizing the crushing of the fault point 51. Preferably, a grinding control button is provided on the controller 9, and the start and stop of the rotation driving mechanism 2 are controlled by pressing the grinding control button. Of course, the controller 9 is also electrically connected to the telescopic driving mechanism for controlling the operation of the telescopic driving mechanism, controlling the telescopic movement of the telescopic mechanism, so that the grinding mechanism 1 retracts into the protective cover 3 or extends out of the protective cover 3 to grind the fault point 51; a telescopic control button is provided on the controller 9, and the start and stop of the telescopic driving mechanism 6 are controlled by pressing the telescopic control button, thereby improving the telescopic movement of the telescopic mechanism 6.

[0026] In this embodiment, the wire reel 8 includes: a box body 81, a main shaft, and a rocker 82; wherein, the main shaft is arranged in the box body 81 and is rotatably connected to the box body 81 for winding and unwinding the cable 7. The rocker 82 is arranged outside the box body 81, and the rocker 82 is connected to the main shaft for driving the main shaft to rotate. Specifically, a through hole 811 is formed in the box body 81, and the main shaft or the rocker 82 passes through the through hole 811 to realize the fixed connection between the main shaft and the rocker 82, and then the rotation of the rocker 82 drives the rotation of the main shaft, thereby realizing the winding and unwinding of the cable 7 to adjust the length of the cable 7 between the wire reel 8 and the rotation driving mechanism 2. Among them, the rocker 82 can be an L-shaped structural member, and one end of the L-shaped structural member is connected to the center point position of the main shaft, that is, one end of the rocker 82 passes through the side wall of the box body 81 and is connected to the main shaft. Of course, the main shaft can also be driven by a driving motor, and no limitation is made in this embodiment. An outlet 812 can be provided on the box body 81, and the cable 7 passes out through the outlet 812 to connect the rotation driving mechanism 2.

[0027] See Figure 4, which is a schematic structural diagram of the inner support fixing mechanism provided by an embodiment of the present invention. As shown in the figure, there are multiple inner support fixing mechanisms 4, which are arranged in a scattered manner along the circumferential direction of the protective cover 3. Specifically, the inner support fixing mechanisms 4 are distributed along the radial direction of the protective cover 3 so as to support the to-be-processed wire tube 5 from multiple directions inside the to-be-processed wire tube 5, and are used to expand the to-be-processed wire tube 5 into a circular shape so that the cylinder section is fixed to the rotary support platform, so that the cylinder section can rotate stably with the rotary support platform 3, thereby ensuring the stability of the butt welding of the cylinder sections. That is, multiple inner support fixing mechanisms 4 can be combined into an inner support circular mechanism to expand and press the to-be-processed wire tube 5 from the inside of the to-be-processed wire tube 5, so that the inner support fixing mechanism 4 fits with the inner wall of the to-be-processed wire tube 5, completes the circular expansion and fixing of the to-be-processed wire tube 5, and further realizes the relative fixation between the to-be-processed wire tube 5 and the protective cover 3. Multiple inner support fixing mechanisms 4 are arranged in a scattered manner along the circumferential direction of the protective cover 3. Preferably, the inner support fixing mechanisms 4 are evenly arranged along the circumferential direction of the protective cover 3 to ensure the pressing stability between the inner support fixing mechanism 4 and the to-be-processed wire tube 5.

[0028] Continue to refer to Figure 4 , the inner support fixing mechanism 4 includes: a telescopic driving member 41 and a circular expansion friction member 42; wherein, one end of the telescopic driving member 41 is connected to the protective cover 3, and the other end is connected to the circular expansion friction member 42, and is used to drive the circular expansion friction member 42 to reciprocate along the radial direction of the protective cover 3, so as to expand the to-be-processed wire tube 5 through the circular expansion friction member 42, and realize the relative fixation of the two through the friction between the circular expansion friction member 42 and the to-be-processed wire tube 5. Specifically, the telescopic driving member 41 drives the circular expansion friction member 42 to reciprocate along the radial direction of the protective cover 3, so that the outer wall of the circular expansion friction member 42 fits with the inner wall of the to-be-processed wire tube 5 to complete the circular expansion and fixation of the to-be-processed wire tube 5, and further realizes the relative fixation between the two through the friction between the circular expansion friction member 42 and the to-be-processed wire tube 5, thereby realizing the relative fixation between the rotation driving mechanism 2 and the to-be-processed wire tube 5. To further increase the fitting area between the outer wall of the circular expansion friction member 42 and the inner wall of the cylinder section, preferably, the circular expansion friction member 42 is an arc-shaped sheet structure adapted to the to-be-processed wire tube 5, so that the outer wall of the circular expansion friction member 42 completely adheres to the inner wall of the to-be-processed wire tube 5; more preferably, the outer wall of the circular expansion friction member 42 is coated with a friction layer to increase the friction between the outer wall of the circular expansion friction member 42 and the inner wall of the to-be-processed wire tube 5, and further improve the stability of the rotation driving mechanism 2. Among them, the telescopic driving member 41 is a linear servo cylinder.

[0029] In this embodiment, the controller 9 is also electrically connected to the telescopic driving member 41 to control the telescopic length of the telescopic driving member 41, and further control the distance between the circularity-supporting friction member 42 and the protective cover 3. Specifically, when the rotation driving mechanism 2 moves forward along the pipeline 5 to be processed until it cannot move forward, that is, when it reaches the fault point 51, the controller 9 controls the operation of the telescopic driving member 41, so that the telescopic driving member 41 drives the circularity-supporting friction member 42 to move radially along the protective cover 3 towards the inner wall of the pipeline 5 to be processed until it presses against the inner wall of the pipeline 5 to be processed. Preferably, a pressing control button is provided on the controller 9, and the length adjustment of the telescopic driving member 41 is controlled by pressing the pressing control button. Refer to Figure 3 , a pressure sensor 10 may be provided on the circularity-supporting friction member 42 to send a stop signal when the circularity-supporting friction member 42 presses against the inner wall of the pipeline 5 to be processed; the controller 9 is electrically connected to the pressure sensor 10 to receive the stop signal and control the telescopic driving member 41 to stop telescoping.

[0030] In this embodiment, the cable 7 includes: a power cable and a signal cable arranged side by side; wherein, the power cable is used to transmit and distribute electrical energy to supply power to related driving members such as the rotation driving mechanism 2; the signal cable is a signal transmission tool used to transmit signals to realize signal transmission between the controller 9 and related components such as the rotation driving mechanism 2. Preferably, the outer of the power cable and the signal cable is coated with a protective tube, and the material of the protective tube can be wear-resistant and highly elastic materials such as a glass fiber reinforced layer and a high-pressure low-density polyethylene protective layer.

[0031] The working process of the electrical pipeline clogging clearing device in this embodiment is as follows: First, when a faulty pipeline, that is, the pipeline 5 to be processed, is found, the electrical pipeline clogging clearing device is moved to the periphery of the pipeline 5 to be processed to complete the positioning of the pipeline 5 to be processed. Then, the rocker 82 is rotated to release the cable 7 from the box body 81 and send the cable 7 into the pipeline 5 to be processed, so that the rotary grinding mechanism 1, the rotation driving mechanism 2, the protective cover 3 and the inner support fixing mechanism 4 move forward along the pipeline 5 to be processed as a whole until the rotation driving mechanism 2 cannot move forward, that is, when it reaches the fault point 51. Then, the controller 9 is operated to control the circularity-supporting friction member 42 to be closely fixed to the inner wall of the pipeline 5 to be processed, and the telescopic mechanism 6 is controlled to push the rotary grinding mechanism 1 out of the protective cover 3 to abut against the fault point 51. Finally, the rotation driving mechanism 2 is controlled to start to grind the fault point 51. After the fault point 51 is destroyed, the electrical pipeline clogging clearing device is retracted according to the above reverse operation, and the pipeline is cleared to remove the ground debris from the pipeline, and prepare for wire threading.

[0032] In summary, for the electrical pipeline clogging removal device provided in this embodiment, the inner support fixing mechanism 4 presses against the inner wall of the pipeline 5 to be processed, so that the protective cover 3 is fixed to the pipeline 5 to be processed; the rotation driving mechanism 2 drives the rotation grinding mechanism 1 to grind and destroy the fault point 51 to remove the pipeline fault. The electrical pipeline clogging removal device effectively simplifies the process, increases the effective construction time, improves the construction quality, and at the same time avoids damaging the building structure by traditional construction methods, thereby avoiding the generation of construction waste and also avoiding polluting the construction environment.
