Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipeline cleaning technology, specifically relating to a clamping device and pipeline cleaning equipment for cleaning sewer pipes. Background Technology
[0002] Sewer pipes play a vital role in urban construction. They serve as crucial channels for sewage discharge, ensuring the timely removal of rainwater, domestic wastewater, and industrial wastewater. This prevents sewage accumulation, water pollution, and environmental degradation, and is essential for maintaining ecological balance and the quality of life for residents. Sewer pipe cleaning is necessary for several reasons. Over time, various types of dirt, grease, hair, and other debris accumulate inside the pipes. These substances easily breed bacteria, mold, and other microorganisms, posing a potential threat to residents' health. Sewer pipes that are not cleaned regularly are prone to blockages, leading to poor drainage, preventing timely sewage discharge, and the gradual corrosion of the pipes by grime adhering to the inner walls, shortening their lifespan.
[0003] In existing technologies, there are two main methods for cleaning sewer pipes. One method uses mechanical grippers to remove foreign objects from the pipes, suitable for blockages caused by clothing, hair, etc. The other method uses a high-pressure water hose to flush the inner walls of the pipes with high-pressure water and cleaning agents, suitable for blockages caused by dirt adhering to the inner walls. Since sewer pipes are buried underground and connected to the surface through manholes, high-pressure water flushing requires opening the manhole cover and inserting the high-pressure water hose into the sewer pipes. During this process, the high-pressure water hose rubs against the manhole opening and the inner wall of the sewer pipe inlet. Because the manhole opening and sewer pipe inlet are often made of materials such as concrete or cast iron, this friction can easily damage the outer wall of the high-pressure water hose, affecting its service life. Utility Model Content

[0037] Please refer to the following: Figures 1 to 5 The clamping device and pipe cleaning equipment for cleaning sewer pipes provided in the embodiments of this utility model will be described below.
[0038] Please see Figures 1 to 5 In a first aspect, this utility model provides a clamping device for cleaning sewer pipes, including a fixed bracket 10, a sliding bracket 20, and at least one pipe guide 30. The fixed bracket 10 includes a slide rod 11 and a first clamping part 12, the first clamping part 12 being disposed at one end of the slide rod 11; the sliding bracket 20 is movably disposed on the slide rod 11, the sliding bracket 20 forming a second clamping part, and a clamping space is formed between the first clamping part 12 and the second clamping part; at least one pipe guide 30 is disposed on the fixed bracket 10 and / or the sliding bracket 20, the pipe guide 30 having a limiting space for a flushing pipe 50 to pass through, and when there are multiple pipe guides 30, the limiting spaces of the multiple pipe guides 30 are connected in series to form the passage path of the flushing pipe 50.
[0039] Compared with the prior art, the beneficial effects of the clamping device for cleaning sewer pipes provided in this embodiment of the present invention are:
[0040] The drain pipe cleaning clamping device provided in this embodiment includes a fixed bracket 10, a sliding bracket 20, and a pipe guide frame 30. The fixed bracket 10 includes a sliding rod 11 and a first clamping part 12. The sliding bracket 20 can move along the sliding rod 11 to form a clamping space for accommodating the side wall of the pipe well, and can clamp onto the side wall of the pipe well. The pipe guide frame 30 is used to form a limiting space for the flushing pipe 50 to pass through, and can guide and limit the path of the flushing pipe 50, which can prevent the flushing pipe 50 from being damaged by friction with the well opening or pipe opening when it is conveyed inward or pulled outward, and helps to improve the service life of the flushing pipe 50.
[0041] The fixed bracket 10 includes a slide rod 11 and a first clamping part 12. The slide rod 11 can be a straight rod or an arc-shaped rod, as long as it allows the sliding bracket 20 to slide along it. The first clamping part 12 and the second clamping part can be plate-shaped, block-shaped, or strip-shaped, respectively, and can be used as... Figure 4 and Figure 5 It can be clamped onto the manhole as shown.
[0042] The sliding bracket 20 is movably mounted on the slide rod 11 and can adjust its position relative to the first clamping part 12 to adapt to pipe wells with different clamping heights. The sliding bracket 20 can be adjusted manually and limited by locking screws, clamps, limit pins, etc. Alternatively, the sliding bracket 20 can also be automatically moved using an electric telescopic rod. The structure of fixing and limiting the sliding bracket 20 using locking screws, clamps, limit pins, etc., is existing technology. For example, a threaded hole can be made in the sliding bracket 20, and a locking screw can be installed in the threaded hole. When it is necessary to fix the sliding bracket 20, the locking screw is screwed into the hole so that the end of the locking screw abuts against the fixed bracket 10.
[0043] The pipe guide 30 is provided on at least one of the fixed support 10 or the sliding support 20. The pipe guide 30 has a limiting space for the flushing pipe 50 to pass through. By providing the pipe guide 30, it is possible to prevent the flushing pipe 50 from being damaged by friction with the wellhead or pipe opening when it is sent into or pulled out of the water pipe.
[0044] As needed, the pipe guide bracket 30 can be fixedly connected to the fixed bracket 10 or the sliding bracket 20, or it can be installed and fixed by a detachable connection such as screw connection.
[0045] Please see Figure 1 In some possible embodiments, the cross-section of the slide rod 11 in the direction perpendicular to its own length is a non-circular surface (irregular surface), and the sliding bracket 20 has a sliding hole that runs through the length of the slide rod 11. The sliding hole slides and engages with the slide rod 11, which can prevent the sliding bracket 20 from rotating around the slide rod 11.
[0046] Please see Figures 1 to 3 In some possible embodiments, there are multiple pipe guide frames 30, wherein at least one pipe guide frame 30 is disposed on the sliding support 20 and at least one pipe guide frame 30 is disposed on the second clamping part, which can effectively guide the flushing pipe 50.
[0047] Please see Figures 1 to 3 In some possible embodiments, the pipe guide frame 30 is provided with two guide wheels, which are rotatably disposed within the limiting space. The space between the two guide wheels is used for the flushing pipe 50 to pass through. The guide wheels are rotatably disposed, and the outer periphery of the guide wheels has a groove for accommodating the flushing pipe 50, which can reduce the frictional resistance when the flushing pipe 50 is sent in or pulled out.
[0048] Please see Figures 1 to 3 In some possible embodiments, the sidewall of the limiting space is provided with an adjustment hole 32. The adjustment hole 32 is elongated. One guide wheel is movably disposed in the adjustment hole 32, and the other guide wheel is fixed in position. The length direction of the adjustment hole 32 is set along the direction close to or away from the fixed guide wheel, so that the position of the guide wheel can be adjusted, and the distance between the two guide wheels can be adjusted to accommodate flushing pipes 50 of different diameters.
[0049] Please see Figures 1 to 3 In some possible embodiments, the second clamping part is further provided with a clamping device 40, which is used to provide clamping force to the sliding bracket 20 so that the sliding bracket 20 and the first clamping part 12 can be firmly clamped on the pipe well.
[0050] Please see Figure 1 and Figure 3 In some possible embodiments, the clamp 40 includes a rotating shaft 41, a pressure block 42, and a handle 43. The rotating shaft 41 is disposed in the second clamping part; the pressure block 42 has a receiving groove, and the second clamping part is partially received in the receiving groove. The side wall of the receiving groove is provided with an adjustment hole 32 that slides with the rotating shaft 41; the handle 43 is rotatably disposed on the rotating shaft 41, one end of the handle 43 is received in the receiving groove, and is provided with a shaped wheel. The outer peripheral surface of the shaped wheel is used to abut against the pressure block 42.
[0051] In this embodiment, the clamp 40 specifically includes a rotating shaft 41, a pressure block 42, and a handle 43. The end of the handle 43 that abuts against the pressure block 42 has a shaped wheel (such as a cam). Rotating the handle 43 causes the shaped wheel to push the pressure block 42 downward, making the pressure block 42 press firmly against the wellhead of the pipe well, thus achieving a secure clamping. When removal is required, simply rotate the handle 43 in the opposite direction so that the shaped wheel is no longer in contact with the pressure block 42.
[0052] It is understandable that when the handle 43 is turned to press the pressure block 42 against the wellhead, the sliding bracket 20 will be subjected to a corresponding reaction force. Under the action of the reaction force, even without the use of locking screws or other locking structures, the sliding bracket 20 can be locked onto the slide rod 11.
[0053] Please see Figure 1 and Figure 3 In some possible embodiments, the clamp 40 further includes a ratchet 44, which is located in the second clamping part and coaxially arranged with the rotating shaft 41. The handle 43 has a pawl that engages with the ratchet 44 and a trigger 431 connected to the pawl. The trigger 431 is used to drive the pawl to engage or disengage from the ratchet 44. The trigger 431 can drive the pawl and ratchet 44 to engage or disengage through a transmission structure such as a shaft, connecting rod, spring, or slider. This transmission method is a common structure of the clamp 40 and will not be described in detail here.
[0054] Please see Figures 1 to 5 In some possible embodiments, the slide bar 11 is a straight bar, and the extension direction of the first clamping part 12 is perpendicular to the length direction of the slide bar 11.
[0055] Secondly, this utility model provides a pipe cleaning device, including the above-mentioned clamping device for cleaning sewer pipes, a high-pressure water pump, and a flushing pipe 50. The flushing pipe 50 is a rubber hose. One end of the flushing pipe 50 is connected to the outlet of the high-pressure water pump, and the other end of the flushing pipe 50 is guided by a pipe guide frame 30. In use, the high-pressure water pump is driven by a fuel engine or an electric motor, which can continuously deliver high-pressure water to the flushing pipe 50. The operator delivers the flushing pipe 50 into the pipe from the ground. The flushing pipe 50 gradually penetrates into the inner wall of the pipe to flush the inner wall of the pipe.
