[0039] The present invention provides a pipeline cleaning system 100 .

[0040] Reference Figures 1 to 8 The pipeline cleaning system 100 in one embodiment of the present invention comprises: a pipeline cleaning vehicle 10, the pipeline cleaning vehicle 10 comprises a shell 11, a driving wheel 13 is provided at the bottom of the shell 11, the driving wheel 13 drives the pipeline cleaning vehicle 10 to penetrate into the interior of the pipeline, the top and / or the side of the shell 11 are further provided with auxiliary wheels 15, the auxiliary wheels 15 can be extended and retracted relative to the shell 11 to abut against the inner wall of the pipeline; a nozzle assembly 20, the nozzle assembly 20 can be rotatably arranged on the shell 11; and a water supply assembly 30, the water supply assembly 30 at least partially penetrates into the interior of the pipeline and is fixed to the shell 11, and is connected to the nozzle assembly 20.

[0041] In the pipeline cleaning system 100 of the technical solution of the present invention, a pipeline cleaning vehicle 10 is designed, and a rotatable nozzle assembly 20 is arranged on the shell 11 of the pipeline cleaning vehicle 10, and the nozzle assembly 20 is connected to the water supply assembly 30, that is, at least a part of the water supply assembly 30 can penetrate into the interior of the pipeline under the traction of the pipeline cleaning vehicle 10 to provide an intermittent water source for the nozzle assembly 20. When the inner wall of the pipeline is cleaned, the driving wheel 13 rotates so that the pipeline cleaning vehicle 10 moves along the extension direction of the pipeline in the pipeline, and the water supply assembly 30 provides a water source for the nozzle assembly 20, and the nozzle assembly 20 rotates uninterruptedly to spray high-pressure water flow to the inner wall of the pipeline to achieve cleaning of the inner wall of the pipeline. In addition, the auxiliary wheel 15 is arranged on the top or side of the shell 11 of the pipeline cleaning vehicle 10, and pressure can be applied to the inner wall of the pipeline from multiple directions, ensuring that the pipeline cleaning vehicle 10 can run smoothly and without slipping in the pipeline, and ensuring the smooth operation of the pipeline cleaning system 100. Compared with the manual cleaning in the existing solutions, the pipeline cleaning system 100 provided in the present invention has the advantages of high cleaning efficiency and the ability to penetrate deep into the inner wall of a long pipeline.

[0042] It should be noted that the nozzle assembly 20 in one embodiment of the present invention includes a connection seat 21 and a nozzle 23, wherein the connection seat 21 is fixed to the housing 11, and the nozzle 23 is relatively installed and rotatable. The rotatable setting of the nozzle 23 facilitates the cleaning of various parts of the inner wall of the pipeline, thereby improving the cleaning quality and cleaning efficiency of the pipeline.

[0043] In some embodiments, the nozzle 23 is provided with a plurality of water outlet holes (not shown), which are arranged circumferentially around the surface of the nozzle 23, and the water outlet holes are also arranged at an acute angle to the surface of the nozzle 23, so that the direction of the water flow can better flush the inner wall of the pipe. Since the water outlet holes are arranged at an acute angle to the surface of the nozzle 23, when the high-pressure water flow is ejected from the water outlet holes, driving forces in different directions are generated on the nozzle 23, thereby driving the nozzle 23 to rotate relative to the housing 11, and then the nozzle assembly 20 can be rotated, thereby achieving 360-degree cleaning of the inner wall of the pipe without dead ends, ensuring the comprehensiveness of the pipe cleaning. However, in this scheme of driving the automatic rotation of the nozzle 23 by ejecting high-pressure water flow, the requirements for the high-pressure water pump are relatively high, and the rotation speed direction of the nozzle 23 is not easy to control.

[0044] In some embodiments, a driving member can also be provided to drive the nozzle assembly 20 to rotate. Specifically, the fourth driving member 25 is fixed to the shell 11 and electrically connected to the circuit board. The fourth driving member 25 drives the nozzle assembly 20 to rotate relative to the shell 11 through the transmission gear 27 to clean the inner wall of the pipe 360°, thereby improving the cleaning quality of the pipe.

[0045] Furthermore, in some embodiments, a water pressure sensor (not shown) can be provided on the nozzle. In this way, the water pressure sensor allows the operator to obtain the magnitude of the water pressure, and then adjust the rotation speed of the fourth driving member 25 according to the magnitude of the water pressure, so that the rotation speed of the nozzle assembly 20 is adapted to the water pressure, thereby ensuring the cleaning speed per unit area of ​​the inner wall of the pipe by the water flow ejected by the nozzle 23, thereby realizing the adjustment of the cleanliness of the pipe cleaning by the pipe cleaning robot.

[0046] Furthermore, a pressure regulating device (not shown) can be added at the water inlet of the nozzle assembly 20 to adjust the water pressure to ensure that the water flow ejected by the nozzle 23 can thoroughly flush the inner wall of the pipe. In addition, the pressure regulating device can also effectively reduce the pressure loss caused by the water flow in the water pipe 31 during long-distance transportation due to the long length of the water pipe 31, thereby reducing the requirements for the high-pressure water pump.

[0047] The housing 11 in one embodiment of the present invention is roughly in the shape of a rectangular parallelepiped, wherein the length direction of the housing 11 is consistent with the extension direction of the pipeline. Usually, the driving wheel 13 is arranged at the lower part of the housing 11, and there are at least two driving wheels 13, which are arranged on both sides of the housing 11. The driving wheels 13 can also be four, six, eight, etc. It can be understood that the driving wheels 13 are arranged in pairs, which facilitates the smooth movement of the pipeline cleaning vehicle 10.

[0048] The auxiliary wheel 15 may be arranged on the side of the shell 11, or on the top surface of the shell 11. The number of auxiliary wheels 15 may be one, and one auxiliary wheel 15 is centrally arranged in the middle of the top of the shell 11. The number of auxiliary wheels 15 may also be two, or four, six, eight, ten, etc. The auxiliary wheels 15 may also be arranged on both the top and side surfaces of the shell 11, or on one of the top and side surfaces. It should be noted that in order to ensure that the pipe cleaning vehicle 10 can maintain balance during the forward movement, the auxiliary wheels 15 are preferably arranged in pairs and symmetrically, so as to avoid the imbalance of the pipe cleaning vehicle 10 during the forward movement and improve the balance performance of the pipe cleaning vehicle 10.

[0049] Reference Figures 1 to 6 In one embodiment of the present invention, the pipe cleaning vehicle 10 further includes a telescopic mechanism 17 , one end of which is fixed to the surface of the shell 11 , and the other end is connected to the auxiliary wheel 15 , so that the auxiliary wheel 15 can move closer to or away from the shell 11 .

[0050] In one embodiment of the present invention, a telescopic mechanism 17 is provided on the pipeline cleaning vehicle 10, and the telescopic mechanism 17 is used to adjust the position of the auxiliary wheel 15 relative to the housing 11. When the pipeline cleaning vehicle 10 travels in pipelines with different inner diameters, it can also ensure that the auxiliary wheel 15 can apply pressure to the inner wall of the pipeline, so as to avoid the situation that the pipeline cleaning vehicle 10 and the inner wall of the pipeline are not sufficiently adhered to each other, so as to prevent the pipeline cleaning vehicle 10 from slipping and other situations that affect the forward movement of the pipeline cleaning vehicle 10, so as to ensure that the pipeline cleaning vehicle 10 can travel more smoothly in pipes with different inner diameters, thereby improving the flexibility and versatility of the pipeline cleaning vehicle 10.

[0051] It should be noted that the telescopic mechanism 17 has various forms. The telescopic mechanism 17 can be directly connected to the auxiliary wheel 15 or indirectly connected to the auxiliary wheel 15. As long as the telescopic mechanism 17 can be fixed to the shell 11 and drive the auxiliary wheel 15 to move closer to or away from the shell 11, the technicians can reasonably select the corresponding telescopic mechanism 17 according to the specific setting position of the auxiliary wheel 15.

[0052] It is understandable that the telescopic mechanism 17 can be a linear motor, or an electric cylinder, etc. This type of electronically controlled telescopic mechanism 17 operates accurately and is easy to control the telescopic accuracy.

[0053] In some embodiments, the telescopic mechanism 17 can also be a non-electrically controlled structure, for example, it can be an elastic structure, such as an arc-shaped elastic steel sheet or a spring assembly. One end of the elastic structure is connected to the auxiliary wheel 15, and the other end is against the surface of the shell 11. This type of elastic structure can also control the auxiliary wheel 15 to move closer to or away from the shell 11.

[0054] The telescopic mechanism 17 includes a fixed body 171 and a movable body 173 movably connected to the fixed body 171. It is understandable that the telescopic mechanism 17 can be composed of a linear motor, and the fixed body 171 and the movable body 173 are correspondingly formed into a motor structure and a slide structure of the linear motor, or the telescopic mechanism 17 can also be composed of a driving cylinder or a hydraulic cylinder, and the fixed body 171 and the movable body 173 are formed into a cylinder body and a piston rod structure.

[0055] For example, when the telescopic mechanism 17 is composed of a linear motor, the motor structure of the linear motor can be detachably fixed to the shell 11, the slide structure of the linear motor is movably connected to the motor structure through a screw, and the auxiliary wheel 15 is rotatably connected to the slide structure of the linear motor. When the motor structure of the linear motor drives the slide structure of the linear motor to move, it drives the auxiliary wheel 15 connected to the slide structure to move closer to or away from the shell 11, so that the auxiliary wheel 15 is in contact with the inner wall of the pipe, which is suitable for cleaning of pipes with different diameters.

[0056] For another example, when the telescopic mechanism 17 is composed of a cylinder, the cylinder body of the cylinder can be connected to the shell 11, and one end of the piston rod can be connected to the auxiliary wheel 15. In this way, when the piston rod reciprocates relative to the cylinder body, the auxiliary wheel 15 can be pushed or pulled away from or closer to the shell 11, so that the auxiliary wheel 15 is in contact with the inner wall of the pipe, which is suitable for cleaning pipes of different diameters.

[0057] like Figure 6 As shown, when the housing 11 of the pipeline cleaning vehicle 10 is an integral body, the driving wheel 13 is arranged at the bottom of the housing 11, and a receiving cavity is formed inside the housing 11. A first driving member 19 is arranged in the receiving cavity. The output shaft of the first driving member 19 extends out of the housing 11 and is in transmission connection with the driving wheel 13 to drive the pipeline cleaning vehicle 10 to penetrate into the pipeline and move forward along the extension direction of the pipeline. The auxiliary wheel 15 is fixed to the top and / or side of the housing 11, the fixed body 171 of the telescopic mechanism 17 is fixed to the housing 11, and the movable body 173 is connected to the auxiliary wheel 15. The telescopic mechanism 17 moves to make the auxiliary wheel 15 approach or move away from the housing 11.

[0058] like Figures 1 to 5When the shell 11 of the pipeline cleaning vehicle 10 is a split structure, the shell 11 includes a first shell 111 and a second shell 113. At this time, the driving wheel 13 is arranged at the bottom of the first shell 111, and a first accommodating chamber 1115 is formed inside the first shell 111. A first driving member 19 is arranged in the first accommodating chamber 1115. The output shaft of the first driving member 19 extends out of the first shell 111 and is connected to the driving wheel 13 in a transmission manner to drive the pipeline cleaning vehicle 10 to penetrate into the pipeline and move forward along the extension direction of the pipeline. The auxiliary wheel 15 is fixed to the top and / or side of the second shell 113, the fixed body 171 of the telescopic mechanism 17 is fixed to the first shell 111, and the movable body 173 is fixed to the second shell 113. The telescopic mechanism 17 moves to make the second shell 113 approach or move away from the first shell 111, so as to make the auxiliary wheel 15 approach or move away from the first shell 111.

[0059] In one embodiment of the present invention, when the shell 11 of the pipe cleaning vehicle 10 is a split structure, the first shell 111 and the second shell 113 are stacked from bottom to top, and a driving wheel 13 is provided at the bottom of the first shell 111, and a first driving member 19 is provided in the first accommodating cavity 1115 formed inside the first shell 111, wherein the first driving member 19 can be a driving motor equipped with a reduction box, which is heavy and also conducive to maintaining the balance of the pipe cleaning vehicle 10. Auxiliary wheels 15 can be provided on the side and / or top surface of the second shell 113. In this way, the fixed body 171 of the telescopic structure is connected to the first shell 111, and the movable body 173 of the telescopic mechanism 17 is connected to the second shell 113. The telescopic structure drives the second shell 113 to rise or fall relative to the first shell 111. This structure can facilitate the installation of the telescopic mechanism 17. Since the auxiliary wheels 15 are disposed on the side and / or top surface of the second housing 113 , when the telescopic structure drives the second housing 113 to rise or fall relative to the first housing 111 , the auxiliary wheels 15 are also driven to move away from or closer to the first housing 111 .

[0060] It should be noted that the first housing 111 includes a first housing bottom shell 1111 and a first housing upper cover 1113 detachably connected to the bottom cover of the first housing 111. The first housing bottom shell 1111 and the first housing upper cover 1113 are detachably covered to form the first accommodating chamber 1115, so as to facilitate the installation of the first driving member 19. The second housing 113 is also detachably covered by the second housing bottom shell 1131 and the second housing upper cover 1133 to form the second housing bottom shell 1131. It should be noted that the second housing bottom shell 1131 also forms a third accommodating chamber 1139 with the second housing inner cover 1135. The third accommodating chamber 1139 is arranged in parallel with the second accommodating chamber 1137. The second accommodating chamber 1137 contains a power module 57, wherein the power module 57 is a battery, and an electric control element is arranged in the third accommodating chamber 1139. The battery provides electric energy for the first driving member 19 and the electronic control element. In some embodiments, the power module 57 may also be external and connected to the external power module 57 via a power module 57 line.

[0061] It should be noted that the electric control components include a circuit board, a controller 51, a pressure sensor 55, a tension sensor 56, a visual detector 53, etc. The pressure sensor 55, the tension sensor 56, and the visual detector 53 are all connected to the controller 51 signal to cooperate with the cleaning work of the pipe cleaning vehicle 10. Further, in order to prevent water from damaging the electric control components, a waterproof structure is usually provided on the first shell 111 and the second shell 113 to prevent water from invading the interior of the shell 11 to ensure the normal operation of the electric control components. The shell 11 of the pipe cleaning vehicle 10 is set as a split structure. When the interior of the pipe cleaning machine needs to be maintained, the second shell 113 or the first shell 111 connected to the second shell 113 can be selectively removed to perform targeted maintenance on the pipe cleaning machine without having to disassemble and assemble the entire machine. This not only greatly reduces the difficulty and workload of disassembly and maintenance, but also improves work efficiency.

[0062] In some embodiments, the pipe cleaning vehicle 10 also includes a second driving member (not shown), which is disposed inside the second shell 113. The output shaft of the second driving member extends out of the surface of the second shell 113 and is transmission-connected to the auxiliary wheel 15. The second driving member is electrically connected to the power module 57 and the controller 51. The second driving member drives the auxiliary wheel 15 to rotate, thereby providing partial driving force for the pipe cleaning vehicle 10.

[0063] Reference Figure 1 In one embodiment of the present invention, the water supply assembly 30 includes a high-pressure water pump and a water pipe 31. The high-pressure water pump is arranged on the outside of the pipeline to be cleaned. One end of the water pipe 31 is connected to the high-pressure water pump, and the other end extends into the interior of the pipeline and is connected to the nozzle assembly 20.

[0064] In one embodiment of the present invention, the water supply assembly 30 includes a high-pressure water pump (not shown) and a water pipe 31. The high-pressure water pump is arranged on the outside of the pipeline. The water pipe 31 is connected to the water inlet of the nozzle assembly 20 through an adapter to provide an uninterrupted water source for the nozzle assembly 20. In order to enable the nozzle 23 to continuously spray high-pressure water to the inner wall of the pipeline to flush the dirt accumulated on the inner wall of the pipeline, a high-pressure water pump is arranged on the outside of the pipeline. The high-pressure water pump can provide a high-pressure and fast-flowing water flow to the water pipe 31 to ensure that the nozzle assembly 20 can spray a water flow that can flush away the dirt to the inner wall of the pipeline.

[0065] Reference Figures 1 to 3 In one embodiment of the present invention, the water supply assembly 30 also includes a connecting pipe 39, which is detachably fixed to the surface of the shell 11, one end of the connecting pipe 39 is connected to the nozzle assembly 20, and the other end is connected to the water pipe 31.

[0066] In one embodiment of the present invention, the connecting pipe 39 is a rigid pipe, and the connecting pipe 39 extends from the front side of the shell 11 to the rear side of the shell 11, and the connecting pipe 39 is detachably connected to the shell 11 through a pressing block (not shown). In some embodiments, a mounting groove (not shown) is recessed on the surface of the shell 11, and the pressing block is detachably covered with the mounting groove to fix the connecting pipe 39 on the shell 11. The setting of the connecting pipe 39 can facilitate the connection between the nozzle assembly 20 set at the front end of the shell 11 and the water pipe 31 dragged at the rear side of the shell 11, thereby improving the disassembly and assembly efficiency of the water pipe 31 and the nozzle assembly 20. When the shell 11 is a split structure, the connecting pipe 39 is fixed between the first shell 111 and the second shell 113, wherein the mounting groove is set on the surface of the first shell 111 facing the second shell 113, and the pressing block is detachably connected to the first shell 111 through a connecting piece (not shown) to detachably clamp and fix the connecting pipe 39 between the pressing block and the first shell 111. In addition, the inner surface of the pressing block and the inner surface of the mounting groove may be provided with an anti-skid structure (not shown). The anti-skid structure may be an anti-skid rib or an anti-skid convex point to increase the friction between the connecting tube 39 and the housing 11 and improve the stability of the fixing of the connecting tube 39 and the housing 11.

[0067] In some embodiments, the lower surface of the second housing 113 is also recessed to form a clearance space to provide a fixing space for the connecting pipe 39. When the housing 11 is an integral structure, a clearance hole (not shown) can be recessed in the housing 11, and a flange is provided at one end of the connecting pipe 39 close to the nozzle assembly 20. The connecting pipe 39 passes through the clearance hole, and the flange abuts against the surface of the housing 11 and is fixed to the housing 11 through a connector.

[0068] Reference Figure 1 to Figure 2In one embodiment of the present invention, the water supply pipe 31 has a connecting section 311 connected to the nozzle assembly 20, and the water supply assembly 30 also includes an anti-pull-off assembly 37, one end of the anti-pull-off assembly 37 is fixed to the shell 11, and the other end is connected to the side of the connecting section 311 of the water supply pipe 31 away from the nozzle assembly 20, and the extension length of the anti-pull-off assembly 37 is less than or equal to the length of the connecting section 311.

[0069] In one embodiment of the present invention, the water pipe 31 is a flexible pipe, and the end of the water pipe 31 close to the connecting pipe 39 is a connecting section 311, and the extension length of the connecting section 311 of the water pipe 31 is defined as L1;

[0070] The anti-stripping assembly 37 includes a first fixed end 373 fixed to the housing 11, a second fixed end 371 fixed to the side of the connecting section 311 of the water pipe 31 away from the nozzle assembly 20, and a chain 375 connected between the first fixed end 373 and the second fixed end 371, and the extension length between the first fixed end 373 and the second fixed end 371 is defined as L2, satisfying the relationship: L2≤L1. In this way, when the pipeline cleaning vehicle 10 drags the water pipe 31 forward in the pipeline to be cleaned, since the extension length of the anti-stripping assembly 37 is less than or equal to the length of the connecting section 311, the anti-stripping assembly 37 bears most of the pulling force of the housing 11 on the water pipe 31, thereby reducing the pulling force directly borne by the water pipe 31, thereby preventing the water pipe 31 from loosening due to excessive pulling force, and preventing the water pipe 31 from falling off from the nozzle under the action of high water pressure and / or strong pulling force, thereby ensuring the normal use of the pipeline of the pipeline cleaning vehicle 10.

[0071] Furthermore, the first fixed end 373 is provided with a fixed block, which is detachably connected to the housing 11 by screws, and the second fixed end 371 is an openable and closable clamp, which facilitates the detachable connection between the second fixed end 371 and the water pipe 31. The chain 375 and the first fixed end 373 can be a detachably connected structure, and the chain 375 and the second fixed end 371 can also be a detachably connected structure. Further, the chain 375 can be an iron chain, a drawstring, a steel wire, or other flexible materials with high hardness.

[0072] Furthermore, a tension sensor 56 may be provided between the fixed block and the chain 375. It should be noted that in order to ensure the accuracy of the reading of the tension sensor 56, a mounting groove needs to be provided on the surface of the housing 11. The mounting groove is provided horizontally and extends along the pipe of the housing 11, so that the tension sensor 56 can be ensured to be in a horizontal position. In addition, the provision of the mounting groove also facilitates the installation of the fixed block and the tension sensor 56. In one embodiment of the present invention, by providing a tension sensor 56 in the anti-stripping assembly 37, it is possible to clearly understand whether the vehicle body has a backward pulling force, so as to know whether the water pipe 31 is detached from the anti-stripping assembly 37, and to provide a basis for judging whether the cleaning vehicle needs to continue to move forward, thereby ensuring the stability between the water pipe 31 and the two mechanisms.

[0073] Reference Figure 1 and Figure 6 In one embodiment of the present invention, the water supply assembly 30 further includes a plurality of trustee devices 35 , and the plurality of trustee devices 35 are spaced apart and sleeved on the surface of the water pipe 31 .

[0074] In an embodiment of the present invention, the trustee device 35 includes a bracket 351, which is sleeved on the surface of the water pipe 31; a plurality of pulley assemblies 353 are arranged around the outer surface of the bracket 351, and each group of pulley assemblies 353 includes a pulley body 3531 and brackets 3533 arranged at both ends of the pulley body 3531, and the pulley body 3531 on the pulley assembly 353 can rotate relative to the bracket 351. When the pipeline cleaning vehicle 10 pulls the water pipe 31 forward in the pipeline, since the bracket 351 is sleeved on the outer surface of the water pipe 31, the plurality of pulley assemblies 353 are around the outer surface of the bracket 351. That is, several pulley bodies 3531 lift up the bracket 351 and the water pipe 31 in the bracket 351, so that the water pipe 31 does not directly contact the inner wall of the pipe. The pulley body 3531 replaces the water pipe 31 to contact the inner wall of the pipe, thereby converting the sliding friction between the water pipe 31 and the inner wall of the pipe into rolling friction, thereby reducing the forward resistance of the pipe cleaning vehicle 10, which is beneficial to the movement of the pipe cleaning vehicle 10.

[0075] Reference Figure 1 In one embodiment of the present invention, the water supply assembly 30 further includes a pipe collecting rack 33 , wherein the pipe collecting rack 33 is disposed on the outside of the pipeline to be cleaned, and the water pipe 31 is rolled up on the pipe collecting rack 33 .

[0076] In one embodiment of the present invention, a pipe collecting rack 33 is provided on the outer side of the pipeline, and a rotating shaft (not shown) is rotatably provided on the pipe collecting rack 33. The rotation of the rotating shaft can facilitate the water pipe 31 to be rolled up on the pipe collecting rack 33. The rotation of the rotating shaft can also release the water pipe 31 rolled up on the pipe collecting rack 33, so as to facilitate the pipeline cleaning vehicle 10 to pull the water pipe 31 deep into the interior of the pipeline.

[0077] Reference Figure 7 In one embodiment of the present invention, the pipeline cleaning system 100 also includes an electronic control module 50, and the electronic control module 50 includes a controller 51 arranged inside the shell 11 and a control terminal 52 arranged outside the pipeline to be cleaned. The controller 51 is electrically connected to the first driving member 19, and the controller 51 is signal-connected to the control terminal 52.

[0078] In one embodiment of the present invention, the controller 51 is disposed inside the housing 11. It should be noted that a circuit board is also disposed inside the housing 11, and the controller 51 is mounted on the circuit board, and the circuit board is electrically connected to the power module 57. When the housing 11 is a split structure, the third accommodating cavity 1139 formed by the second housing 113 is an electric control room, and electric control components such as the circuit board are all disposed in the electric control room. It should be noted that the electric control room is a sealed structure, so that water can be prevented from entering the electric control and causing a short circuit of the circuit components.

[0079] Furthermore, the control terminal 52 can be a control handle, a PLC (programmable logic controller) computer console, an IPA or other terminal control device, which is not limited here. The control terminal 52 is connected to the controller 51 by signal. The control terminal 52 can control the start or stop of the pipeline cleaning vehicle 10, and can also control the forward speed of the pipeline pulling vehicle. It should be noted that the control terminal 52 and the controller 51 are connected by signals. In one embodiment of the present invention, a signal transceiver (not shown) is also provided. The signal transceiver is arranged on the outside of the pipeline. The signal transceiver is connected to the controller 51 through a signal line, and the signal transceiver is connected to the control handle through a wireless signal. Furthermore, the signal line is arranged along the extension line of the water pipe 31. Furthermore, the signal line can be fixed to the hosting device 35 to avoid problems such as messy routing of the signal line. Figure 7 As shown, area I in the bracket is used to fix the water pipe 31, and area II is used to fix the signal line.

[0080] Reference Figure 8 In one embodiment of the present invention, the electric control module 50 further includes a visual detector 53, which is disposed on the surface of the shell 11 and is electrically connected to the controller 51. The visual detector 53 collects an image of the inner wall of the pipeline after cleaning to detect the cleanliness of the inner wall of the pipeline.

[0081] In one embodiment of the present invention, the visual detector 53 is a camera, wherein the camera may be a camera with an infrared imaging function, and the camera is fixed on the surface of the housing 11. More specifically, the camera is fixed on the front surface and the rear surface of the housing 11, so that the image of the inner wall of the pipeline before and after cleaning can be collected to determine whether the inner wall of the pipeline is clean.

[0082] Furthermore, in order to improve the quality of the captured image, a light source 54 can be provided on the surface of the housing 11, and the light source 54 can be fixed on one side of the camera. The camera displays the captured image in the video display area of ​​the control terminal 52 through signal transmission, so that the operator can manually control the forward speed of the pipeline cleaning vehicle 10 and the rotation speed of the nozzle assembly 20 by observing the image in the video display area to ensure that the inner wall of the pipeline is cleaned. In addition, the controller 51 can also automatically compare the image captured by the camera and automatically control the forward speed of the pipeline cleaning vehicle 10 and the rotation speed of the nozzle assembly 20. The visual detector 53 can realize the visual operation during the cleaning process of the inner wall of the pipeline, thereby improving the flexibility and reliability of the pipeline cleaning process.

[0083] Reference Figure 7 In one embodiment of the present invention, the electronic control module 50 further includes a pressure sensor 55, which is disposed on the auxiliary wheel 15 and is electrically connected to the controller 51 to detect the pressure between the auxiliary wheel 15 and the inner wall of the pipeline.

[0084] In one embodiment of the present invention, the pressure sensor 55 can detect the change in pressure between the pipeline cleaning vehicle 10 and the inner wall of the pipeline, and then determine the change in the diameter of the pipeline. At the same time, the telescopic mechanism 17 is activated, and the telescopic mechanism 17 is extended to make the auxiliary wheel 15 approach or move away from the housing 11, so that the distance between the two is changed accordingly to adapt to the change in the diameter of the pipeline, thereby improving the passability of the pipeline cleaning vehicle 10 and ensuring that the pipeline cleaning vehicle 10 can adapt to walking smoothly in pipelines with different inner diameters.

[0085] Reference Figure 7 In one embodiment of the present invention, the electronic control module 50 also includes a tension sensor 56, which is arranged between the first connection end of the anti-slip assembly 37 and the shell 11, and the tension sensor 56 is electrically connected to the controller 51 to detect the tension of the anti-slip assembly 37 on the water pipe 31.

[0086] In one embodiment of the present invention, the model of the tension sensor 56 is DYLY-106. The setting of the tension sensor 56 can timely obtain the tension of the anti-slip assembly 37, so as to determine whether the water pipe 31 is separated from the anti-slip assembly 37, so that the operator can adjust the pipeline cleaning vehicle 10 in time. In addition, the setting of the tension sensor 36 can also detect whether there is rearward pressure on the pipe cleaning vehicle 10, and transmit the detected tension to the controller 51. The controller 51 determines whether the pressure value exceeds the first threshold. When the tension sensor 36 detects that the tension of the pipe cleaning vehicle 10 is less than the first threshold, the controller 51 controls the pipe cleaning vehicle 10 to move forward at a constant speed; when the tension sensor 36 detects that the tension of the pipe cleaning vehicle 10 is greater than the first threshold, the controller 51 controls the pipe cleaning vehicle 10 to stop sliding forward, and the controller 51 controls the pipe cleaning vehicle 10 to slide backward, and manually operates the pipe collecting rack 33 to drag the water pipe 31 to the outside, so as to pull the water pipe 31 and the pipe cleaning vehicle 10 out of the outside of the pipe to be cleaned.
