Description

Technical Field

[0001] The present application relates to the technical field of pipeline cleaning, and in particular to a pipeline cleaning robot. Background Art

[0002] Underground pipelines are a vital component of urban infrastructure, and their cleaning and maintenance are crucial to ensuring the smooth operation of cities. However, due to the narrow interior spaces and complex environments of pipelines, manual cleaning is difficult. Therefore, desilting robots are often used to flush the pipelines with high-pressure water jets and to remove waste using suction devices, thereby achieving complete cleaning.

[0003] Regarding the above-mentioned related technologies: There are usually some large particles of dirt in the pipeline, which are easy to clog the sewage suction device when being sucked by the sewage suction device, resulting in the sewage suction device being unable to discharge the dirt from the pipeline, thereby reducing the cleaning efficiency. Summary of the Invention

[0004] In order to improve cleaning efficiency, the present application provides a pipeline cleaning robot.

[0005] This application provides a pipeline cleaning robot that adopts the following technical solutions:

[0006] A pipeline cleaning robot, comprising:

[0007] A body, wherein a sewage suction port is provided on the body;

[0008] A sewage suction mechanism is provided on the machine body and is connected to the sewage suction port, and is used to suck the sewage in the pipeline and discharge the sewage out of the pipeline;

[0009] The cleaning mechanism includes a water spray assembly and a linkage assembly. The water spray assembly is hinged on the top of the fuselage, and the linkage assembly is respectively connected to the water spray assembly and the sewage suction mechanism. When the sewage suction port is blocked, the linkage assembly can drive the water spray assembly to rotate so that the water spray assembly flushes the sewage suction port.

[0010] By adopting the above technical solution, when the pipeline needs to be cleaned, the main body is first placed into the pipeline. The main body drives the suction mechanism and the cleaning mechanism into the pipeline, so that the high-pressure water flow sprayed by the water spray assembly can flush the pipeline. At this time, the suction mechanism can suck the dirt in the pipeline through the suction port and discharge the sucked dirt out of the pipeline to complete the cleaning of the pipeline. During this process, if the suction port is blocked, the linkage assembly can drive the water spray assembly to rotate, so that the water spray assembly sprays high-pressure water flow toward the suction port to flush the dirt at the suction port, thereby facilitating the unblocking of the suction port, allowing the suction mechanism to discharge the dirt out of the pipeline, thereby improving the cleaning efficiency.

[0011] Optionally, the sewage suction mechanism includes a sewage suction component and a sewage collecting component, and the sewage suction component and the sewage collecting component are respectively arranged on the body, the sewage suction component is connected to the linkage component and communicated with the sewage suction port, and the sewage collecting component is located below the sewage suction port, and the sewage collecting component is used to collect the dirt in the pipe to the sewage suction port.

[0012] By adopting the above technical solution, after the water spray component flushes the dirt on the inner wall of the pipe, the dirt collecting component can collect the dirt in the pipe to the sewage suction port, so that the sewage suction component can absorb the dirt and discharge it out of the pipe, which is beneficial to reduce the residual dirt in the pipe and thus help improve the cleaning effect.

[0013] Optionally, the sewage suction component includes a sewage suction pump and a sewage suction pipe, the sewage suction pump and the sewage suction pipe are respectively installed in the fuselage, the sewage suction pump is connected to the sewage suction pipe, one end of the sewage suction pipe is connected to the sewage suction port, the other end of the sewage suction pipe extends out of the fuselage, and the linkage component is connected to the sewage suction pipe.

[0014] By adopting the above technical solution, when it is necessary to discharge the sewage from the pipeline, the sewage suction pump is started to form a negative pressure in the sewage suction pipe, thereby facilitating the suction of sewage into the sewage suction port and further facilitating the discharge of sewage from the pipeline through the sewage suction pipe.

[0015] Optionally, the linkage assembly includes a connecting sleeve, a connecting block, an elastic member and a pull rope. The connecting sleeve is connected to the sewage suction pipe. A sliding groove is opened on the inner wall of the connecting sleeve along its own axial direction. The elastic member is arranged in the sliding groove. The connecting block is slidably inserted in the connecting sleeve and fits with the inner wall of the connecting sleeve. A slider is provided on the connecting block. The slider is slidably inserted in the sliding groove and connected to the elastic member. The elastic member is used to push the slider to move away from the sewage suction pipe. The pull rope is respectively connected to the connecting block and the water spray assembly.

[0016] By adopting the above technical solution, when the sewage suction pump is working and the sewage suction port is blocked, the negative pressure in the sewage suction pipe increases, causing the negative pressure in the connecting sleeve to increase, thereby applying a greater suction force to the connecting block, so that the connecting block applies pressure to the elastic member through the slider, compressing the elastic member and moving the connecting block toward the sewage suction pipe. At this time, the connecting block rotates the water spray assembly through the pull rope, so that the high-pressure water flow sprayed by the water spray assembly can flush the sewage suction port to clear the sewage suction port, thereby facilitating the sewage suction pump to continuously discharge sewage from the pipeline through the sewage suction pipe. And when the sewage suction port is cleared, the suction force on the connecting block decreases, so that the pressure applied by the connecting block to the elastic member through the slider is reduced, so that the elastic member pushes the connecting block to move away from the sewage suction pipe, so that the connecting block is reset.

[0017] Optionally, the water spray assembly includes a mounting seat, a rotating nozzle and a water pipe. The mounting seat is hinged to the fuselage. A through hole is provided in the mounting seat. The water pipe is connected to the through hole. The rotating nozzle is rotatably connected to the mounting seat and connected to the through hole. One end of the pull rope is connected to the mounting seat.

[0018] By adopting the above technical solution, the water pipe can transmit high-pressure water through the through-hole to the rotating nozzle, allowing the rotating nozzle to spray high-pressure water to flush out dirt in the pipe. Furthermore, the mounting base is hinged to the body, allowing the connecting block to rotate the mounting base via a pull cord, which in turn drives the rotating nozzle to rotate. This allows the high-pressure water sprayed by the rotating nozzle to flush out dirt at the sewage suction port, thereby reducing the possibility of the sewage suction port being clogged.

[0019] Optionally, a reset member is provided between the mounting seat and the body, and the reset member is used to drive the mounting seat to reset.

[0020] By adopting the above technical solution, the reset member can drive the mounting seat to reset, and the mounting seat can drive the rotating nozzle to reset, thereby making it easier to use the rotating nozzle to flush the dirt in the pipeline.

[0021] Optionally, the sewage collecting component includes a sewage collecting bucket, which is arranged on the fuselage and located below the sewage suction port. The sewage collecting bucket is adapted to the inner wall design of the pipeline and is used to collect sewage in the pipeline to the sewage suction port.

[0022] By adopting the above technical solution, when the fuselage moves in the pipeline, the sewage collecting bucket can scoop up the sewage in the pipeline and concentrate the sewage at the sewage suction port, which is beneficial to reduce the possibility of sewage being deposited at the bottom of the pipeline on the one hand, and facilitates the sewage suction component to absorb the sewage and discharge the sewage out of the pipeline on the other hand.

[0023] Optionally, a filter is provided in the sewage suction port, and the filter is located on the side of the fuselage close to the water spray assembly. The sewage collecting assembly includes a sewage collecting box, and the sewage collecting box is provided at the bottom of the fuselage. A feed port is provided on the side of the sewage collecting box close to the sewage collecting bucket, and a feed chute is provided on the sewage collecting bucket. The feed chute is provided close to the filter and is connected to the feed port.

[0024] By adopting the above technical solution, when dirt is concentrated at the sewage suction port and the sewage suction component sucks up the dirt, the filter can filter the dirt so that small particles of dirt enter the sewage suction port, while large particles of dirt are blocked outside the sewage suction port. During this process, most of the large particles of dirt can fall into the sewage collection box through the drop chute and the feed port in sequence. This is beneficial to reduce the possibility of large particles of dirt clogging the sewage suction port on the one hand, and on the other hand, it is beneficial to reduce the possibility of large particles of dirt re-entering the pipeline, thereby improving the cleaning efficiency. The filter is located on the side of the machine body close to the water spray component, so that the high-pressure water flow sprayed by the water spray component can directly flush the filter, which is beneficial to improve the cleaning efficiency of the filter.

[0025] Optionally, the sewage collecting box is connected to a sewage discharge pipe, and a double-screw conveying mechanism is provided in the sewage collecting box, and the double-screw conveying mechanism is used to crush large particles of sewage and convey them to the sewage discharge pipe.

[0026] By adopting the above technical solution, the double-screw conveying mechanism can crush large particles of dirt and transport them to the sewage pipe, reducing the possibility of blockage of the sewage pipe to a certain extent, thereby facilitating the discharge of dirt from the pipe, reducing the possibility of excessive dirt stored in the sewage collection box causing large particles of dirt to no longer fall into the sewage collection box, and thus facilitating the stable function of the sewage collection box during the pipeline cleaning process, thereby improving the cleaning efficiency to a certain extent.

[0027] Optionally, a walking mechanism is provided at the bottom of the fuselage, a support frame is provided at the top of the fuselage, and a roller is rotatably connected to the support frame, and the roller can contact the inner wall of the pipe.

[0028] By adopting the above technical solution, when the fuselage is placed in the pipe, the walking mechanism can drive the fuselage to move in the pipe, and the rollers can contact the inner wall of the pipe, so that the rollers and the support frame can support the fuselage, so as to reduce the possibility of shaking of the fuselage when moving in the pipe, thereby helping to reduce the possibility of the fuselage rolling over in the pipe.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. Through the cooperation of the water spray component, linkage component and sewage suction mechanism, when the sewage suction port is blocked, the linkage component can drive the water spray component to flush the sewage suction port to dredge the sewage suction port, thereby facilitating the sewage suction mechanism to discharge the sewage into the pipeline through the sewage suction port, thereby improving the cleaning efficiency;

[0031] 2. Through the mutual cooperation of the sewage suction pump, sewage suction pipe, connecting sleeve, connecting block, slider, elastic member, pull rope, mounting seat, rotating nozzle, water pipe and reset member, when the sewage suction port is blocked, the connecting block can be subjected to greater suction force, so that the connecting block moves in the direction close to the sewage suction pipe, and the connecting block pulls the mounting seat to rotate through the pull rope, so that the high-pressure water flow ejected by the rotating nozzle is used to flush the sewage at the sewage suction port to dredge the sewage suction port. When the sewage suction port is dredged, the suction force on the connecting block is reduced, the elastic member can drive the connecting block to reset, and the reset member can drive the mounting seat to reset, thereby facilitating the rotating nozzle to flush the sewage in the pipe;

[0032] 3. Through the cooperation of the sewage collecting bucket, filter screen, sewage collecting box and sewage suction component, small particles of sewage can be discharged from the pipeline through the sewage suction component, and large particles of sewage can fall into the sewage collecting box. This is beneficial to reduce the possibility of the sewage suction port being blocked on the one hand, and on the other hand, it is beneficial to reduce the possibility of large particles of sewage falling back into the pipeline;

[0033] 4. The double-screw conveying mechanism and the sewage pipe work together to break up large particles of dirt in the sewage collection box and convey them out of the pipe, thereby reducing the possibility of excessive dirt in the sewage collection box preventing large particles from falling into the sewage collection box, and thus facilitating the stable function of the sewage collection box during the pipeline cleaning process.

[0034] 5. Through the cooperation of the walking mechanism, support frame and rollers, the fuselage is not easy to shake when moving in the pipeline, which is helpful to reduce the possibility of the fuselage rolling over. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following is combined with Figure 1-6 This application is described in further detail.

[0044] An embodiment of the present application discloses a pipeline cleaning robot.

[0045] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Embodiment 1:

[0046] Reference Figure 1 The pipe cleaning robot includes a body 1, a suction mechanism 2, and a cleaning mechanism 3. A suction port 11 is provided on the body 1. The suction mechanism 2 and the cleaning mechanism 3 are mounted on the body 1, and the suction mechanism 2 is connected to the suction port 11. The suction mechanism 2 can suck dirt from the pipe through the suction port 11 and discharge the dirt from the pipe. The cleaning mechanism 3 is used to flush the dirt from the pipe. When the suction port 11 is blocked, the cleaning mechanism 3 can flush the suction port 11 to clear it, thereby facilitating the suction mechanism 2 to discharge the dirt from the pipe, thereby improving cleaning efficiency.

[0047] Reference Figure 2The bottom of the body 1 is equipped with two running mechanisms 4, which are symmetrically distributed. In this embodiment, the running mechanisms 4 are crawler-type to adapt to the environment within the pipeline, thereby facilitating the use of the two running mechanisms 4 to cooperate with each other to drive the body 1 to move within the pipeline. It should be noted that the specific structure of the running mechanisms 4 is a conventional technical means for those skilled in the art and is therefore not described in detail in the embodiments of this application.

[0048] Reference Figure 1 A support frame 12 is mounted on the top of the chassis 1, and a plurality of rollers 13 are rotatably connected to the support frame 12. When the chassis 1 enters the pipeline, the running mechanism 4 contacts the bottom of the pipeline, and the rollers 13 contact the top of the pipeline. This facilitates the running mechanism 4 to drive the chassis 1 to move within the pipeline, and also facilitates supporting the chassis 1 to reduce the possibility of shaking when the chassis 1 moves within the pipeline, thereby helping to reduce the possibility of the chassis 1 rolling over within the pipeline.

[0049] Reference Figure 3 The sewage suction mechanism 2 includes a sewage suction component 21 and a sewage collecting component 22. The sewage suction component 21 and the sewage collecting component 22 are respectively arranged on the body 1, the sewage suction component 21 is connected to the sewage suction port 11, and the sewage collecting component 22 is located below the sewage suction port 11.

[0050] The sewage suction assembly 21 includes a sewage suction pump 211 and a sewage suction pipe 212. The sewage suction pump 211 and sewage suction pipe 212 are separately installed within the machine body 1. The sewage suction pump 211 is connected to the sewage suction pipe 212. One end of the sewage suction pipe 212 is connected to the sewage suction port 11, and the other end of the sewage suction pipe 212 extends out of the machine body 1. When the sewage suction pump 211 is activated, it creates a negative pressure within the sewage suction pipe 212, thereby drawing sewage from the sewage suction port 11 into the sewage suction pipe 212 and facilitating its discharge through the sewage suction pipe 212.

[0051] A filter screen 14 is installed in the sewage suction port 11. The filter screen 14 can filter the dirt so that small particles of dirt can be sucked into the sewage suction pipe 212, while large particles of dirt can be blocked outside the sewage suction port 11, thereby reducing the possibility of the sewage suction port 11 or the sewage suction pipe 212 being blocked to a certain extent.

[0052] Reference Figure 3 The sewage collecting assembly 22 includes a sewage collecting bucket 221 and a sewage collecting box 222. The sewage collecting bucket 221 is mounted on the fuselage 1 and is located below the sewage suction port 11. The sewage collecting bucket 221 is adapted to the inner wall of the pipe so that the sewage collecting bucket 221 can fit the inner wall of the pipe.

[0053] When the fuselage 1 moves in the pipeline, the sewage collecting bucket 221 can scoop up the sewage at the bottom of the pipeline, and as the fuselage 1 moves forward, the sewage can move in the sewage collecting bucket 221 toward the sewage suction port 11, so that the sewage is concentrated at the sewage suction port 11, thereby facilitating the suction of the sewage into the sewage suction pipe 212, and thus helping to reduce the possibility of sewage being deposited at the bottom of the pipeline.

[0054] It should be noted that the sewage collecting bucket 221 is detachably connected to the fuselage, so that the sewage collecting bucket 221 can be replaced, and then the size and shape of the sewage collecting bucket 221 can be adjusted according to actual needs, so that the sewage collecting bucket 221 can stably scoop up the dirt at the bottom of the pipe.

[0055] Reference Figure 3 The dirt collecting bucket 221 is provided with a chute 2211, which is arranged close to the filter screen 14. The dirt collecting box 222 is installed at the bottom of the fuselage 1, and a feed port 2221 is provided on one side of the dirt collecting bucket 221, which is connected to the chute 2211.

[0056] When dirt is collected at the sewage suction port 11 and the sewage suction pump 211 is operating, small particles of dirt can pass through the filter screen 14 and enter the sewage suction pipe 212, while large particles of dirt will be blocked by the filter screen 14 outside the sewage suction port 11. At this time, under the action of gravity, the large particles of dirt can sequentially fall into the sewage collection box 222 through the drop chute 2211 and the feed port 2221, thereby reducing the possibility of large particles of dirt re-entering the pipe and improving the cleaning effect.

[0057] Reference Figure 2 and Figure 3 The cleaning mechanism 3 includes a water spray assembly 31 and a linkage assembly 32. The water spray assembly 31 includes a mounting base 311, a rotating nozzle 312, and a water pipe 313. The mounting base 311 is hinged to the body 1, and a reset member 3111 is provided between the mounting base 311 and the body 1. In this embodiment, the reset member 3111 is a torsion spring. When the mounting base 311 rotates relative to the body 1, the reset member 3111 can drive the mounting base 311 to reset.

[0058] It should be noted that, in the embodiment of the present application, the specific hinge structure adopted between the mounting base 311 and the fuselage 1 is a conventional technical means for those skilled in the art, and therefore will not be elaborated in detail in the embodiment of the present application.

[0059] Reference Figure 3A through hole 3112 is defined within the mounting base 311. The rotating nozzle 312 is rotatably connected to the mounting base 311 and communicates with the through hole 3112. A water pipe 313 is mounted on the body 1. One end of the water pipe 313 communicates with the through hole 3112, and the other end of the water pipe 313 communicates with an external water delivery device. The external water delivery device is used to deliver water to the water pipe 313, thereby allowing the water pipe 313 to transport the water through the through hole 3112 to the rotating nozzle 312, causing the rotating nozzle 312 to spray high-pressure water. In this embodiment, the water pipe 313 is a hose, which makes it less likely to obstruct the rotation of the mounting base 311.

[0060] Reference Figure 3 and Figure 4 The linkage assembly 32 includes a connecting sleeve 321, a connecting block 322, an elastic member 323, and a pull rope 324. The connecting sleeve 321 is installed in the housing 1 and communicates with the sewage suction pipe 212. A sliding groove 3211 is defined on the inner wall of the connecting sleeve 321 along its axis, and the elastic member 323 is disposed within the sliding groove 3211. In this embodiment, the elastic member 323 is a spring.

[0061] The connecting block 322 is slidably inserted into the connecting sleeve 321 and abuts against the inner wall of the connecting sleeve 321. The connecting block 322 is integrally formed with a slider 3221, which is slidably inserted into the chute 3211 and fixedly connected to the elastic member 323. In this embodiment, the connecting block 322 can block the chute 3211 to prevent dirt from entering the chute 3211.

[0062] One end of the pull rope 324 is fixedly connected to the end of the connecting block 322 away from the sewage suction pipe 212, and the other end of the pull rope 324 is fixedly connected to the mounting seat 311, so that when the connecting block 322 moves toward the sewage suction pipe 212, the connecting block 322 can pull the mounting seat 311 to rotate through the pull rope 324, so that the mounting seat 311 drives the rotating nozzle 312 to rotate, thereby facilitating the rotating nozzle 312 to spray high-pressure water flow toward the filter screen 14 to flush the filter screen 14.

[0063] In other embodiments, the filter 14 may not be provided in the sewage suction port 11 , and the high-pressure water flow sprayed by the rotating nozzle 312 can directly flush the sewage suction port 11 to clear the sewage suction port 11 when it is blocked.

[0064] Reference Figure 1 A camera 5 is installed on the top of the fuselage 1. The camera 5 can transmit monitoring images in real time so that the staff can observe the situation in the pipeline and control the operation of the pipeline cleaning robot.

[0065] The implementation principle of a pipeline cleaning robot in Example 1 of the present application is as follows: when the pipeline needs to be cleaned, the body 1 is first placed in the pipeline, so that the walking mechanism 4 drives the body 1 to move in the pipeline and causes the roller 13 to contact the top of the pipeline. Then, water is supplied to the rotating nozzle 312 using the water pipe 313, so that the rotating nozzle 312 sprays high-pressure water to flush the dirt in the pipeline. At this time, the walking mechanism 4 drives the body 1 to gradually move forward. During this process, the sewage collecting bucket 221 scoops up the dirt at the bottom of the pipeline and collects the dirt on the filter 14. The sewage suction pump 211 works, sucking small particles of dirt into the sewage suction pipe 212 and discharging them from the pipeline through the sewage suction pipe 212, while large particles of dirt are blocked outside the sewage suction port 11 and fall into the sewage collection box 222 through the drop chute 2211 and the feed port 2221 in turn. Finally, the above process is continued to complete the cleaning of the pipeline.

[0066] When the filter screen 14 is clogged and the sewage suction pump 211 continues to operate, the negative pressure in the sewage suction pipe 212 increases, causing the negative pressure in the connecting sleeve 321 to increase, thereby applying a greater suction force to the connecting block 322, causing the connecting block 322 to move closer to the sewage suction pipe 212. The connecting block 322 drives the slider 3221 to move, and the slider 3221 applies pressure to the elastic member 323, compressing the elastic member 323. During this process, the connecting block 322 pulls the mounting base 311 to rotate via the pull rope 324, causing the mounting base 311 to rotate and the rotating nozzle 312 to rotate, causing the rotating nozzle 312 to spray a high-pressure water flow toward the filter screen 14, thereby flushing the filter screen 14 and thereby clearing the filter screen 14.

[0067] When the filter 14 is cleared, the suction force on the connecting block 322 decreases, allowing the elastic member 323 to drive the connecting block 322 to return to its original position via the slider 3221. This, in turn, allows the return member 3111 to drive the mounting base 311 to return to its original position, thereby facilitating the rotating nozzle 312 to flush the dirt in the pipe again. At this point, the dirt can be sucked into the suction pipe 212 for easy discharge from the pipe.

[0068] In the embodiment of the present application, through the mutual cooperation of the sewage suction pump 211, the sewage suction pipe 212, the connecting sleeve 321, the connecting block 322, the slider 3221, the elastic member 323, the pull rope 324, the mounting seat 311, the rotating nozzle 312, the water pipe 313 and the reset member 3111, when the filter 14 is blocked, the rotating nozzle 312 can automatically clean and unclog the filter 14 without the need to move the fuselage 1 out of the pipeline first, thereby facilitating the continuous operation of the pipeline cleaning robot and thus improving the cleaning efficiency. Example 2:

[0069] Reference Figure 5 The difference between this embodiment and embodiment 1 is that a double-screw conveying mechanism 6 is provided in the dirt collecting box 222 .

[0070] Reference Figure 5 and Figure 6 The double-screw conveying mechanism 6 includes two spiral shafts 61, which are parallel to each other and hinged in the dirt collecting box 222. Each spiral shaft 61 is equipped with a spiral blade 62, and the spiral blades 62 on the two spiral shafts 61 are staggered. In this embodiment, a motor is used to drive the two spiral shafts 61 to rotate. It should be noted that how to use a motor to drive the two spiral shafts 61 to rotate is a conventional technical means for those skilled in the art. Therefore, it will not be described in detail in the embodiments of this application.

[0071] One end of the sewage collecting box 222 away from the feed port 2221 is connected to a sewage discharge pipe 2222 , and the sewage discharge pipe 2222 extends out of the pipeline from one end away from the sewage collecting box 222 .

[0072] When the two spiral shafts 61 rotate, the spiral shafts 61 drive the spiral blades 62 to rotate, so as to break up the large particles of dirt and transport them to the sewage pipe 2222, thereby facilitating the discharge of the dirt from the pipeline, thereby reducing the possibility that too much dirt is stored in the sewage collecting box 222, resulting in large particles of dirt no longer being able to fall into the sewage collecting box 222, and to a certain extent reducing the possibility of blockage in the sewage pipe 2222, thereby facilitating the stable functioning of the sewage collecting box 222 during the pipeline cleaning process, thereby improving the cleaning efficiency to a certain extent.

[0073] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
