Description

Technical Field

[0001] The present invention relates to the technical field of pipeline desilting equipment, and more particularly to a pipeline desilting robot and a working method thereof. Background Art

[0002] Municipal drainage pipes are important infrastructure projects for modern cities to control pollution, prevent flooding and drain water, and they deeply affect and dominate the development of cities. During the use of pipes, it is inevitable that sediment residues, dirt or debris will be produced on the inner wall of the fluid channel of the pipes. Due to the deposition and adhesion of these dirt, debris or residues on the pipe wall, the diameter of the pipe will continue to shrink during use, thereby affecting the working efficiency of the pipe. If the pipes are not cleaned in a timely and effective manner, when the deposition reaches a certain level, it will seriously affect the normal use of the pipes and cause serious consequences. Therefore, in order to ensure the normal operation of the drainage system, it is necessary to regularly clean the sediments in the drainage pipes and repair the defects of the drainage pipes in time. The existing large pipe dredging method mainly relies on manual dredging, which is to enter the pipes by frogmen or use sewage suction trucks to clean the internal silt and other sediments. However, for pipes with smaller diameters, manual entry is impossible, so a pipe dredging robot is needed for cleaning.

[0003] Most of the existing pipe dredging robot brush heads can only swing in a fixed direction to form a fan-shaped effective cleaning area, which has low efficiency and cannot achieve 360° cleaning of the pipe. Pipe dredging robots that can achieve all-round cleaning have problems such as being unable to adapt to pipes of different inner diameters and the brush head blade adjustment mechanism being easily damaged. Summary of the invention

[0004] In view of this, the present invention provides a pipeline dredging robot to solve the problems of low dredging efficiency and inability to adapt to pipelines with different inner diameters of the existing dredging robots.

[0005] To achieve the above-mentioned purpose, the pipeline dredging robot provided by the present invention comprises a dredging device and a vehicle body arranged at the rear end of the dredging device, wherein the dredging device and the vehicle body are connected to each other by a connecting section; The desilting device comprises a threaded drill bit, a sleeve and a fan blade, wherein the threaded drill bit is arranged at the front end of the sleeve, and the fan blade is arranged at the side wall of the sleeve. The vehicle body comprises a shell and a driving wheel, and a plurality of supporting devices are arranged on the outer side wall of the shell. The end of the supporting device away from the shell is connected to the driving wheel, and the distance between the driving wheel and the shell is adjusted by the supporting device so that the driving wheel abuts against the pipe walls of different pipe diameters. The support device comprises a deformer and a bracket, wherein the deformer comprises a spring and a hydraulic rod, and the bracket comprises two straight rods, and the connection part of the two straight rods is hinged; The driving wheel is provided with a hub motor.

[0006] Preferably, the connecting section comprises a protective shell and a main rod, the protective shell is fixedly arranged at one end of the outer shell close to the dredging device, and the main rod is sleeved inside the protective shell.

[0007] Preferably, a power device is provided inside the shell, and the power device is slidably connected to the rear end of the main rod to drive the main rod forward or backward.

[0008] Preferably, a propulsion device is provided inside the sleeve, and the front end of the main rod is nested and connected with the propulsion device to drive the propulsion device forward or backward.

[0009] Preferably, the propulsion device includes a rotating device and a gear, wherein the gear is arranged at the front end of the rotating device, the gear is gear-engaged with the inner cavity of the threaded drill bit and can slide back and forth along the axis of the threaded drill bit, and the rotating device is provided with a motor for driving the propulsion device to rotate.

[0010] Preferably, a connecting rod is provided between the propulsion device and the fan blades, and the connecting rod and the fan blades are slidably connected.

[0011] Preferably, it is characterized in that a blade hole for inserting a fan blade is provided on the side wall of the sleeve, a groove is provided on the side of the fan blade, the groove is arranged in an oblique upward direction from front to rear, and one end where the connecting rod and the fan blade are connected is provided with a slider nested in the groove, and the slider can slide back and forth along the groove.

[0012] A working method of the pipeline desilting robot as described above comprises the following steps: When in use, the robot is placed at the entrance of the pipeline, and then the power device is turned on. The power device will push the main rod forward, and the main rod pushes the propulsion device forward. The propulsion device also drives the connecting rod to move forward. The slider on the connecting rod slides along the groove toward the front side of the fan blade. At the same time, the fan blade extends toward the outside of the sleeve along the fan blade hole, so that the pipe diameter range that the outermost side of the fan blade adapts to becomes larger, until the fan blade is close to the inner wall of the pipeline and the propulsion device cannot move forward. Then the hydraulic rod pops up to stick the driving wheel to the pipe wall. The hydraulic rod is driven by the power device to adjust the pipe diameter range that the outermost side of the fan blade and the driving wheel adapt to, so that the dredging device can adapt to pipelines of different diameters. Then turn on the rotating motor in the propulsion device and the hub motor on the driving wheel. The rotating motor drives the propulsion device and the threaded drill bit to rotate. The propulsion device drives the fan blades and the sleeve to rotate through the connecting rod. The fan blades and the threaded drill bit jointly drive the dredging device to rotate and work. The hub motor on the driving wheel drives the driving wheel to rotate, driving the entire equipment forward, and the threaded drill bit impacts and breaks up the obstacles in front of the pipeline, and then further breaks them up through the fan blades. At the same time, the outer edge of the fan blades scrapes off the residue on the side wall of the pipeline, thereby achieving dredging of the pipeline.

[0013] It can be seen from the above technical solution that compared with the prior art, the present invention scrapes off the sediment attached to the inner wall of the pipe through the rotating fan blades, and at the same time the rotating threaded drill bit has an impact effect, which breaks up the foreign matter at the front end and sends it to the fan blades. The rotating fan blades further disperse the blocked foreign matter to achieve dredging inside the pipe. The water brought up by the rotating fan blades softens the sediment on the wall of some long-abandoned dry pipes, making it easier to wash away the sediment on the inner wall of the pipe, thereby achieving dredging of the pipe.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Please refer to the attached Figure 1-7 , which is a pipeline dredging robot disclosed in the present invention.

[0025] like Figure 1 As shown, the pipeline desilting robot provided by the present invention comprises a desilting device 1, a vehicle body 2 and a connecting section 3. The vehicle body 2 is arranged at the rear end of the desilting device 1, and the two are connected by transmission through the connecting section 3.

[0026] like Figure 2-4 As shown, the dredging device 1 includes a threaded drill bit 11, a sleeve 12 and a fan blade 13. The threaded drill bit 11 is arranged at the front end of the sleeve 12, and the fan blade 13 is arranged on the side wall of the sleeve 12. The vehicle body 2 includes a shell 21 and a driving wheel 24. A plurality of supporting devices 23 are arranged on the outer wall of the shell 21. The end of the supporting device 23 away from the shell 21 is connected to the driving wheel 24. The distance between the driving wheel 24 and the shell 21 is adjusted by the supporting device 23, so that the driving wheel 24 can adapt to different pipe diameter ranges and can abut against pipe walls of different pipe diameters.

[0027] The connecting section 3 includes a protective shell 31 and a main rod 32 . The protective shell 31 is fixed to one end of the outer shell 21 close to the dredging device 1 , and the main rod 32 is sleeved inside the protective shell 31 .

[0028] It should be noted that a power device 22 is provided inside the outer shell 21, and the power device 22 is transmission-connected to the main rod 32 to drive the main rod 32 forward or backward; a propulsion device 15 is provided inside the sleeve 12, and the end of the main rod 32 away from the power device 22 is transmission-connected to the propulsion device 15 to drive the propulsion device 15 forward or backward.

[0029] Specifically, the sleeve 12 and the feed device 15 are connected at the connection between the main rod 32, the protective shell 31 and the outer shell 21 are connected at the connection between the power device 22, the threaded drill bit 11 and the propulsion device 15 are transmission-connected, the front end of the main rod 32 and the propulsion device 15 are nested and connected, and the rear end of the main rod 32 and the power device 22 are slidingly connected.

[0030] Specifically, the propulsion device 15 includes a rotating device 151 and a gear 153. The gear 153 is arranged at the front end of the rotating device 151. The gear 153 is gear-engaged with the inner cavity of the threaded drill bit 11, and the gear 153 can slide back and forth along the axis of the threaded drill bit 11 in the inner cavity of the threaded drill bit 11. The rotating device 151 is provided with a motor 152 for driving the propulsion device 15 to rotate, and the threaded drill bit 11 is driven to rotate by the rotation of the propulsion device 15.

[0031] like Figure 5-6 As shown, a connecting rod 14 is provided between the propulsion device 15 and the fan blades 13. The propulsion device 15 and the connecting rod 14 can be fixed or hinged to increase movement. The connecting rod 14 and the fan blades 13 are slidingly connected. A blade hole 121 for inserting the fan blades 13 is provided on the side wall of the sleeve 12. There is also a groove 131 on the side of the fan blade 13. The groove 131 is arranged in an oblique upward direction from front to rear. A slider 141 is nested in the groove 131 at one end where the connecting rod 14 and the groove 131 are connected. The slider 141 can slide back and forth in the groove 131 to drive the fan blades 13 to extend and retract from the blade hole 121.

[0032] Specifically, when the slider 141 on the connecting rod 14 is in an initial state, it is located at the upper and oblique rear end of the groove 131 on the fan blade 13. After being pushed by the propulsion device 15, the connecting rod 14 moves forward. Since the fan blade 13 is restricted by the blade hole 121 and cannot move forward and backward, the horizontal force transmitted to the fan blade 13 by the connecting rod 14 is decomposed along the direction of the groove 131. In the process of the slider 141 gradually moving toward the front side of the fan blade 13 relative to the groove 131, the fan blade 13 is continuously extended and moved toward the outside of the blade hole 121; similarly, when the slider 141 gradually moves toward the rear side of the fan blade 13 relative to the groove 131, the fan blade 13 can be continuously retracted and moved toward the inside of the blade hole 121.

[0033] like Figure 7 As shown, the support device 23 includes a protective cover 231, a deformer 232 and a bracket 233. The protective cover 231 is made of a compressible material and is sleeved on the outside of the deformer 232 and the bracket 233 to protect the support device 23 from being damaged by debris in the pipeline. The deformer 232 includes a spring 2321 and a hydraulic rod 2322. The two ends of the deformer 232 are respectively connected to the two ends of the bracket 233. The bracket 233 includes two straight rods 2331. The connecting part of the two straight rods 2331 is hinged. One end of the bracket 233 is connected to the shell 21 and the other end is equipped with a driving wheel 24. The driving wheel 24 is provided with a hub motor 241 to drive the entire device forward.

[0034] Specifically, after the robot enters the pipeline, the hydraulic rod 2322 can be popped up, and the spring 2321 can be released from the compressed state, so that the driving wheel 24 can be attached to the pipe wall. Therefore, by popping up the hydraulic rod 2322, the driving wheel 24 can be adjusted to a state that adapts to the pipe wall, and the driving wheel 24 and the pipe wall can always remain in contact, thereby ensuring the robot's ability to move forward, and the spring 2321 can also play a role in buffering and protecting the robot.

[0035] The working method of the pipeline desilting robot provided by the present invention is as follows: When in use, the robot is placed at the entrance of the pipeline, and then the power device 22 is turned on. The power device 22 will push the main rod 32 forward, and the main rod 32 pushes the propulsion device 15 forward. The propulsion device 15 simultaneously drives the connecting rod 14 to move forward, and the slider 141 on the connecting rod 14 slides along the groove 131 toward the front side of the blade 13. At the same time, the blade 13 extends toward the outside of the sleeve 12 along the blade hole 121, so that the pipe diameter range adapted to the outermost side of the blade 13 becomes larger, until the blade 13 is close to the inner wall of the pipeline and the propulsion device 15 cannot move forward any further, and then the hydraulic rod 2322 pops up to attach the driving wheel 24 to the pipe wall, and the hydraulic rod 2322 is driven by the power device 22 to adjust the pipe diameter range adapted to the outermost side of the blade 13 and the driving wheel 24, so that the dredging device 1 can adapt to pipelines of different diameters; Then, the rotating motor 152 in the propulsion device 15 and the hub motor 241 on the driving wheel 24 are turned on. The rotating motor 152 drives the propulsion device 15 and the threaded drill bit 11 to rotate. The propulsion device 15 drives the fan blades 13 and the sleeve 12 to rotate through the connecting rod 14. The fan blades 13 and the threaded drill bit 11 jointly drive the dredging device 1 to rotate and work. The hub motor 241 on the driving wheel 24 drives the driving wheel 24 to rotate, driving the entire equipment to move forward, and the threaded drill bit 11 impacts and breaks up the obstacles in front of the pipeline, and then further breaks them up through the fan blades 13. At the same time, the outer edge of the fan blades 13 scrapes off the residues on the side wall of the pipeline, thereby achieving dredging of the pipeline.
