Abstract
Description
Technical Field
[0001] This application relates to the field of pipeline dredging technology, and in particular to a pipeline dredging and cleaning device. Background Technology
[0002] Drainage pipe networks are pipeline systems used in urban and rural areas to collect, transport, and discharge water (sewage, wastewater, and rainwater). They mainly consist of two parts: sewage pipe networks and rainwater pipe networks, and are an indispensable part of infrastructure. When drainage pipes become blocked, pipe dredging and cleaning devices are needed to unclog and clear the blockages inside the pipes.
[0003] Traditional pipe cleaning devices typically have multiple rollers arranged in a circular array on the outermost side. When cleaning a target pipe, these rollers simultaneously contact the inner wall of the pipe. Because the rollers are on the outermost side of the device, it is difficult to remove stubborn stains adhering to the inner wall of the pipe. Utility Model Content
[0004] This application aims to solve at least one of the technical problems existing in the prior art. To this end, this application proposes a pipe dredging and cleaning device that can effectively clean stubborn stains adhering to the inner wall of the target pipe.

[0030] Drainage pipe networks are pipeline systems used in urban and rural areas to collect, transport, and discharge water (sewage, wastewater, and rainwater). They mainly consist of two parts: sewage pipe networks and rainwater pipe networks, and are an indispensable part of infrastructure. When drainage pipes become blocked, pipe dredging and cleaning devices are needed to unclog and clear the blockages inside the pipes.
[0031] Traditional pipe cleaning devices typically have multiple rollers arranged in a circular array on the outermost side. When cleaning a target pipe, these rollers simultaneously contact the inner wall of the pipe. Because the rollers are on the outermost side of the device, it is difficult to remove stubborn stains adhering to the inner wall of the pipe. Therefore, it is necessary to optimize traditional pipe cleaning devices to solve the aforementioned technical problems. The optimized pipe cleaning device of this application will be described in detail below with reference to the accompanying drawings.
[0032] Reference Figures 1 to 5 The pipe dredging and cleaning device according to an embodiment of this application includes a device body, a roller 200, a scraper 300, and an elastic element.
[0033] Specifically, the main body of the device includes a head 110 and a rod 120. The head 110 is disposed at one end of the rod 120. Rollers 200 are buoyantly disposed on the outer peripheral sidewall of the head 110. There are multiple rollers 200, and all rollers 200 are arranged in a circular array around the axis of the rod 120. A scraper 300 is disposed on the outer peripheral sidewall of the head 110 and extends along the axial direction of the rod 120. A clearance opening 310 is provided on the scraper 300 corresponding to the roller 200. The clearance opening 310 passes through the scraper 300 and is used to avoid the roller 200. An elastic element is used to provide an elastic force to make the roller 200 extend out of the clearance opening 310. When the roller 200 is subjected to an external force, it can move towards the outer peripheral sidewall of the head 110 so that the scraper 300 can act on the inner wall of the target pipe.
[0034] When dredging and cleaning the target pipe, the operator stands at the pipe opening and holds the rod 120, applying force to the rod 120 to insert the head 110 into the target pipe, ensuring that the rod 120 is at least partially outside the target pipe. At this time, applying force radially to the part of the rod 120 outside the target pipe applies pressure to at least one roller 200. The pressurized roller 200 moves towards the outer peripheral sidewall of the head 110, so that the scraper 300 can act on the inner wall of the target pipe. At this time, the force applied radially to the rod 120 is maintained, and force is applied to the rod 120 to drive the head 110 to move back and forth along the extension direction of the target pipe, so that the front side of the scraper 300 can scrape off the stubborn stains attached to the inner wall of the target pipe. During the process of unblocking and cleaning the target pipe, the direction of the force applied radially to the rod 120 is switched at regular intervals to thoroughly scrape away stubborn stains adhering to the inner wall of the target pipe. Compared with the prior art, the pipe unblocking and cleaning device of the present application can better clean stubborn stains adhering to the inner wall of the target pipe.
[0035] Reference Figures 2 to 4 In some embodiments, the scraper 300 is arc-shaped so that it can conform to the inner wall of the target pipe. Multiple scrapers 300 are provided on the outer peripheral side wall of the head 110. All scrapers 300 are arranged in a ring array around the axis of the rod 120. All scrapers 300 correspond one-to-one with all rollers 200. Each scraper 300 is provided with an avoidance opening 310. Its structure is simple and easy to implement.
[0036] Reference Figure 1 and Figure 2In some embodiments, there is a gap between two adjacent scrapers 300 so that the side edge of the scraper 300 can act on the inner wall of the target pipe when the head 110 rotates. When dredging and cleaning the target pipe, force is applied to the rod 120 to drive the head 110 to rotate. At this time, the side edge of the scraper 300 can scrape off stubborn stains attached to the inner wall of the target pipe, so that the operator can choose different scraping methods according to the actual situation.
[0037] Reference Figures 1 to 5 In some embodiments, the scraper 300 and the head 110 have a connection structure, which includes a connecting rod 111 and a support rod 320. One end of the connecting rod 111 is connected to the head 110, one end of the support rod 320 is connected to the scraper 300, and the other end of the support rod 320 is connected to the end of the connecting rod 111 away from the head 110. The roller 200 includes a wheel seat 210 and a wheel body 220 rotatably connected to the wheel seat 210. A guide rod 211 is provided on the side of the wheel seat 210 facing away from the wheel body 220. The guide rod 211 is buoyantly inserted into the end of the connecting rod 111 away from the head 110. The elastic element is a helical spring 400 sleeved on the guide rod 211. Its structure is simple and easy to implement.
[0038] It should be noted that in some embodiments, a limiting structure is provided between the guide rod 211 and the connecting rod 111 to prevent the guide rod 211 from disengaging from the connecting rod 111. One end of the helical spring 400 abuts against the connecting rod 111, and the other end of the helical spring 400 abuts against the wheel seat 210. Specifically, the limiting structure includes a limiting part (not shown in the figure) provided at the end of the guide rod 211 away from the wheel seat 210, a blind hole (not shown in the figure) for inserting the guide rod 211 is provided at the end of the connecting rod 111 away from the head 110, and a blocking part (not shown in the figure) is provided at the open end of the connecting rod 111 corresponding to the blind hole to restrict the limiting part from disengaging from the blind hole.
[0039] It should be noted that in some other embodiments, one end of the helical spring 400 is connected to the connecting rod 111, and the other end of the helical spring 400 is connected to the wheel seat 210; this is not limited here. In this case, the aforementioned limiting structure is not required between the guide rod 211 and the connecting rod 111.
[0040] It should be noted that in some other embodiments, the elastic element can also be a gas spring, which is not limited here. Specifically, one end of the gas spring is connected to the end of the connecting rod 111 away from the head 110, and the other end of the gas spring is connected to the wheel seat 210. In this case, the guide rod 211 mentioned above is not required.
[0041] It should be noted that in some embodiments, the connecting rod 111 is detachably connected to the head 110, thereby enabling the scraper 300 and roller 200 to be removed from the head 110 for maintenance.
[0042] Reference Figure 1 , Figure 2 and Figure 4 In some embodiments, a connecting seat 112 is provided on the outer peripheral sidewall of the head 110 corresponding to the connecting rod 111. The connecting seat 112 has a first threaded connection hole (not shown in the figure). A first threaded connection part 1111 is provided at one end of the connecting rod 111 near the head 110. The first threaded connection part 1111 is threadedly connected to the first threaded connection hole. Its structure is simple and easy to implement.
[0043] It should be noted that in some other embodiments, the end of the connecting rod 111 near the head 110 has a connecting flange, which is connected to the head 110 by screws, and this is not limited here.
[0044] It should be noted that in some other embodiments, the connecting rod 111 may also be integrally formed on the head 110, which is not limited here.
[0045] It should be noted that in some other embodiments, the scraper 300 may also be a closed ring structure and sleeved on the head 110, which is not limited here. In this case, there is only one scraper 300, and the scraper 300 is provided with multiple clearance openings 310 corresponding to all the rollers 200.
[0046] Reference Figure 1 and Figure 2 In some embodiments, the head 110 is provided with a gripper 500 for grabbing blockages on the side facing away from the rod 120. When encountering large blockages during the unblocking and cleaning of the target pipe, the gripper 500 can grab them. The gripper 500 can be an electric gripper or a pneumatic gripper, and is not limited thereto.
[0047] Reference Figure 1 and Figure 2 In some embodiments, a high-pressure nozzle 600 is also provided on the outer peripheral sidewall of the head 110. The high-pressure nozzle 600 is connected to a water supply pipe 610. The end of the water supply pipe 610 away from the high-pressure nozzle 600 is used to connect to an external water source. The high-pressure nozzle 600 is used to spray high-pressure water into the inner wall of the target pipe, thereby flushing the inner wall of the target pipe.
[0048] Reference Figure 2In some embodiments, a plurality of high-pressure nozzles 600 are provided on the outer peripheral sidewall of the head 110, and all the high-pressure nozzles 600 are arranged in a ring array around the axis of the rod portion 120, which is beneficial to improving the flushing effect on the inner wall of the target pipe.
[0049] It should be noted that in some of these embodiments, at least one high-pressure nozzle 600 has its nozzle facing the side where the rod 120 is located. When the operator applies force to the rod 120 to drive the head 110 out of the target pipe, the water jet from the high-pressure nozzle 600 with its nozzle facing the side where the rod 120 is located can help remove blockages from the target pipe.
[0050] It should be noted that in some embodiments, the rod 120 is detachably connected to the head 110 to facilitate the replacement of heads 110 of different sizes to accommodate target pipes of different diameters.
[0051] It should be noted that in some embodiments, a mounting base 113 is provided on the side of the head 110 facing the rod 120. The mounting base 113 has a second threaded connection hole (not shown in the figure). A second threaded connection part (not shown in the figure) is provided at the end of the rod 120 near the head 110. The second threaded connection part is threadedly connected to the second threaded connection hole. Its structure is simple and easy to implement.
[0052] It should be noted that in some other embodiments, the end of the rod 120 near the head 110 has a connecting flange, which is connected to the head 110 by screws, and this is not limited here.
[0053] It should be noted that in some embodiments, the rod 120 is a telescopic structure, which can adapt to different cleaning depths. The telescopic structure of the rod 120 is a well-known technology in the mechanical field, such as the handle of a folding umbrella and the pull rod of a suitcase; its structure and principle will not be elaborated here.
