The silt cleaning device further includes: a telescopic pipe structure, which is a multi-section telescopic structure, the fixed end of the telescopic pipe structure is connected to the mounting seat and communicated with the water inlet pipe, and the movable end of the telescopic pipe is movably connected to the flushing seat; a number of scrapers, which are arranged annularly around the flushing seat, and the scrapers are provided with threaded rods and guide rods, the threaded rods are in threaded cooperation with the flushing seat, and the guide rods are in sliding cooperation with the flushing seat; and a fixing module, which is arranged on the mounting seat and used to fix the mounting seat inside the pipeline body; wherein the telescopic pipe structure includes: a first telescopic pipe, which is arranged on the mounting seat; a second telescopic pipe, which is movably inserted into the first telescopic pipe; a third telescopic pipe, which is movably inserted into the second telescopic pipe; a locking unit, which is arranged between the second telescopic pipe and the first telescopic pipe and used to fix the position of the second telescopic pipe; and a monitoring unit, which is arranged between the second telescopic pipe and the third telescopic pipe and used to monitor the position of the third telescopic pipe inside the second telescopic pipe and control the locking unit to fail. The flushing heads are arranged obliquely relative to the flushing seat. The locking unit includes a damping rod and a group of electromagnets that repel each other when energized; the damping rod is movably arranged inside the second telescopic pipe and one end is in sliding cooperation with the first telescopic pipe, and electromagnets are arranged on the opposite surfaces of the damping rod and the second telescopic pipe.

[0034] The monitoring unit includes a monitoring box, a group of conductive sheets, a first magnet, and a second magnet; the monitoring box is arranged at the end of the second telescopic pipe away from the mounting seat, the second magnet is movably arranged inside the monitoring box and elastically connected to it, conductive sheets are arranged on the opposite surfaces of the second magnet and the monitoring box, the first magnet is arranged at the end of the third telescopic pipe close to the mounting seat, and the first magnet and the second magnet repel each other when they meet.

[0035] The mounting seat is fixed in the pipe body by a fixing module, the water inlet pipe is connected to an external water supply source, water is input into the water inlet pipe through the external water supply source, and the water flows finally from the inner wall of the pipe body of the flushing head box. Since the flushing head is arranged at an angle, the water flow can drive the flushing seat and the scraper to rotate while spraying out from the flushing head, so as to scrape off the silt on the inner wall of the pipe body, and under the friction between the water flow and the No. 3 telescopic pipe, the No. 3 telescopic pipe is driven to extend from the No. 2 telescopic pipe, so that the flushing seat and the scraper move horizontally along the pipe body. When the No. 1 telescopic tube moves to the extreme position, the No. 1 magnet and the No. 2 magnet meet and repel each other, driving the No. 2 magnet to move up in the direction shown in the figure, so that the conductive blocks contact each other, triggering the electromagnet to lose power and fail. At this time, the damping rod and the No. 1 telescopic tube are out of contact, and the water flow can drive the No. 2 telescopic tube to extend out of the No. 1 telescopic tube, thereby effectively cleaning the silt at different positions in the pipeline body. The whole device has a high degree of automation, gets rid of the traditional manual operation of the nozzle to flush the silt on the inner wall of the pipeline, and reduces the labor input.

[0036] The fixing module includes: a plurality of suction cups arranged around the mounting seat; a connecting arm arranged around and movably arranged on the mounting seat, one end of the connecting arm is connected to the suction cup, and the connecting arm is connected to the mounting seat through an elastic member; and an adjusting unit, which is movably arranged on the mounting seat and connected to the connecting arm, and is used to adjust the distance between the suction cup and the mounting seat.

[0037] The adjusting unit comprises an adjusting disk, a rotating disk and a plurality of adjusting protrusions; the adjusting disk is movably arranged on the mounting seat, the rotating disk is movably arranged in the mounting seat and connected to the adjusting disk, and the plurality of adjusting protrusions are arranged on the adjusting disk and slidably cooperate with the other end of the connecting arm.

[0038] A resistance reducing member is provided between the adjusting protrusion and the connecting arm, so as to reduce the friction resistance between the connecting arm and the adjusting protrusion.

[0039] The resistance reducing member may be a ball or a roller. In the present embodiment, the resistance reducing member is preferably a roller, which is movably disposed at the other end of the connecting arm and slidingly cooperates with the adjusting protrusion.

[0040] In addition, the elastic member can be a spring, a spring sheet or an elastic steel plate structure. In the present embodiment, the elastic member is preferably a spring, and the spring is arranged between the connecting arm and the mounting seat. As for the specific model of the spring, no specific limitation is made here.

[0041] When installing the mounting base inside the pipe body with different diameters, by placing the mounting base inside the pipe body and rotating the adjustment disk, the turntable and the adjustment protrusion can be driven to rotate, and the rollers reach different positions on the adjustment arm. Through the abutting cooperation between the adjustment protrusion and the connecting arm, the distance between the suction cup and the mounting base can be adjusted, so that the whole device can be fixed inside the pipe body with different diameters to carry out the silt cleaning work.

[0042] When installing the mounting base inside the pipe body with different diameters, by placing the mounting base inside the pipe body and rotating the adjustment disk, the turntable and the adjustment protrusion can be driven to rotate, and the rollers reach different positions on the adjustment arm. Through the abutting cooperation between the adjustment protrusion and the connecting arm, the distance between the suction cup and the mounting base can be adjusted, so that the whole device can be fixed inside the pipe body with different diameters to carry out the silt cleaning work. Connect the water inlet pipe to an external water supply source, and input water into the water inlet pipe through the external water supply source. The water flow finally reaches the inner wall of the pipe body of the flushing head box. Since the flushing heads are arranged obliquely, the water flow can drive the flushing seat and the scraper to rotate while spraying out from the flushing heads, and the silt on the inner wall of the pipe body can be scraped off. Under the abutting action between the water flow and the third telescopic pipe, the third telescopic pipe is driven to extend out of the second telescopic pipe, so that the flushing seat and the scraper move horizontally along the pipe body. When the third telescopic pipe moves to the limit position, at this time, the first magnet and the second magnet meet and repel each other, driving the second magnet to move upward in the direction shown in the figure, so that the conductive blocks are in contact with each other, triggering the electromagnet to power off and fail. At this time, the damping rod is separated from the first telescopic pipe, and the water flow can drive the second telescopic pipe to extend out of the first telescopic pipe, so as to effectively clean the silt at different positions inside the pipe body. The whole device has a high degree of automation, getting rid of the traditional manual operation of spraying the inner wall of the pipe with a nozzle to clean the silt, and reducing the input of labor.

[0043] The existing Chinese patent discloses a device for cleaning silt in a water conservancy and hydropower project pipeline, with the publication number CN221559239U, which includes a mounting box, a mounting cylinder and an operating cylinder.

[0044] Four grooves arranged in a circumferential array are formed on the left side surface of the mounting cylinder, and the inner wall of the groove is fixedly connected with a second telescopic rod. The telescopic end of the second telescopic rod is fixedly connected to the right side surface of the mounting box. Under the action of the second telescopic rod, the effect of auxiliary load bearing can be achieved, avoiding the gravity of the operating cylinder and the mounting cylinder all acting on the electric push rod.

[0045] A pressing plate is arranged on the surface of the operating cylinder through a spacing adjusting mechanism, a cleaning plate is arranged on the surface of the pressing plate through an elastic mechanism, bristles are arranged on the surface of the cleaning plate, and the elastic mechanism includes a first telescopic rod rotatably connected to the surface of the pressing plate through a rotating seat.

The two ends of the high-pressure spring are respectively fixedly connected to the opposite surfaces of the pressing plate and the cleaning plate.

[0046] The spacing adjusting mechanism includes a transmission cavity opened inside the housing of the operating cylinder. Four mounting grooves arranged in a circumferential array are opened on the surface of the operating cylinder.

The sliding plate 9 is slidably matched with the support column 6, the brush plate 10 is arranged on the sliding plate 9, and the displacement component is used to drive the sliding plate 9 to slide along the support column 6, so that the brush plate 10 and a plurality of cleaning teeth 8 can be switched between a state of abutting and a state of separation.

[0059] By driving the brush plate 10 to move through the displacement component, the brush plate 10 and a plurality of cleaning teeth 8 can be switched between a state of abutting and a state of separation. When cleaning the inner wall of the pipeline, the brush plate 10 and a plurality of cleaning teeth 8 are in a separated state, so that the brush plate 10 contacts the inner wall of the pipeline. Then, the collecting water pipe 4 is driven to rotate through the driving component, driving the support column 6 and the cleaning mechanism to rotate. At the same time, water is sprayed through the collecting water pipe 4 and the high-pressure nozzles 5 to soften the silt, so that the brush plate 10 can clean the inner wall of the pipeline. When it is necessary to clean the brush plate 10, the brush plate 10 and a plurality of cleaning teeth 8 are in an abutting state, and the support column 6 is continuously driven to rotate through the driving component, so that the brush plate 10 continuously crosses a plurality of cleaning teeth 8 as the support column 6 rotates, achieving the effect of cleaning the silt on the brush plate 10 by a plurality of cleaning teeth 8. Thus, the silt on the brush plate 10 can be automatically cleaned inside the pipeline, effectively improving the operation efficiency of the brush plate 10 for cleaning the silt in the pipeline.

[0066] When the brush plate 10 is in the initial position (the brush plate 10 is in contact with a plurality of cleaning teeth 8), since the end of the sliding plate 9 away from the connecting rod 11 is the telescopic rod 15 and the telescopic rod 15 is in the extended state, by pushing the connecting rod 11 through the first electric push rod 14, the connecting rod 11 can push the sliding plate 9 to make the telescopic rod 15 contract. At the same time, the sliding seat 18 and the guiding column 20 move synchronously. When the telescopic rod 15 contracts to the end, the first electric push rod 14 continues to push the connecting rod 11. Through the guiding and limiting of the guiding column 20, the sliding plate 9 can be forced to slide along the guiding column 20, and the connecting rod 11 and the telescopic rod 15 generate a flip, so as to push the brush plate 10 in the direction away from the support column 6, so that the brush plate 10 can contact the inner wall of the pipeline. At this time, the brush plate 10 is in the use position (the brush plate 10 is separated from a plurality of cleaning teeth 8). When it is necessary to clean the brush plate 10, the sliding plate 9 is pulled back to the original position through the first electric push rod 14. The sliding plate 9 can descend along with the guiding column 20 during the movement, and at the same time, the telescopic rod 15 can be forced to expand, so that the brush plate 10 gradually returns to the initial position. Thus, the brush plate 10 can be driven to rotate synchronously by rotating the support column 6, so that the cleaning teeth 8 cross-clean the brush plate 10.

[0067] In one embodiment of the present invention, a plurality of upright columns 21 are fixedly connected to the sliding plate 9, and the ends of the upright columns 21 away from the sliding plate 9 are connected to the brush plate 10 through spring rods 22.

[0068] By arranging the upright columns 21, the position of the brush plate 10 can be raised, so that the brush plate 10 is convenient to contact the inner wall of the pipeline. By arranging the spring rods 22, the brush plate 10 can have a certain tension, improve the contact effect between the brush plate 10 and the inner wall of the pipeline, and improve the dredging effect.
