Description

Technical Field

[0001] This invention belongs to the field of underground pipeline protection technology, specifically relating to a protection device for underground sewage pipelines along roads. Background Technology

[0002] Underground pipelines are pipes laid underground to transport liquids, gases, or loose solids. In cities, underground pipelines are commonly used to discharge domestic sewage, rainwater, and other liquid waste, as well as small particulate solid waste. Pipelines located under roads are in direct contact with the soil and bear pressure. However, under vehicle loads, especially heavy or overloaded conditions, road surfaces often develop defects at an early stage, affecting underground sewage pipelines. This can easily lead to cracks, damage, and misalignment. Since underground pipelines are very long, it is difficult to perform flaw detection and maintenance on the entire pipeline. If cracks appear in underground pipelines, sewage will seep out, polluting the external underground environment.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Reference will now be made in detail to various embodiments of the invention, examples of which are shown in the accompanying drawings and described below. For ease of interpretation and precise definition in the appended claims, the terms “upper,” “lower,” “inner,” and “outer” are used to describe features with reference to their location in the exemplary embodiments shown in the figures.

[0025] Figures 1-6 The following diagrams illustrate the structure of a protective device for an underground sewage pipeline according to an embodiment of the present invention, after installation with the sewage pipeline body, the internal structure of the excavation frame, the internal structure of the maintenance frame, the internal structure of the base, and the structural diagram of the traveling assembly. The present invention provides a protective device for an underground sewage pipeline, as shown in the figures, including a base 1, multiple mounting seats 2 disposed on the base 1, and a sewage pipeline body 4 disposed on the multiple mounting seats 2. It also includes: multiple limiting arc-shaped frames 3 rotatably connected to the multiple mounting seats 2 for limiting the sewage pipeline body 4; a driving rail 5 located inside the sewage pipeline body 4 and fixedly connected to the multiple limiting arc-shaped frames 3; and a protective assembly slidably connected to the driving rail 5 for unblocking the sewage pipeline body 4.

[0026] In related technologies, pipelines located under roads are in direct contact with and bear pressure from the soil. However, under vehicle loads, especially heavy or overloaded conditions, the road surface often suffers damage at an early stage, which can affect the sewage pipelines underground. This can easily cause cracks, damage, and misalignment in the sewage pipelines. By laying the main body 4 of the sewage pipeline on multiple mounting bases 2, the main body 4 of the sewage pipeline can be isolated from the ground through the mounting bases 2, preventing the sewage pipeline from having long-term contact with the water that seeps into and accumulates underground, thus reducing the corrosion of the sewage pipeline by underground water seepage. Furthermore, the main body 4 of the sewage pipeline is further fixed by the limiting arc frame 3, which also serves as an external protective component to protect the main body 4 of the sewage pipeline, thereby improving the external protection capability of the main body 4 of the sewage pipeline. Finally, the internal protection capability of the main body 4 of the sewage pipeline can be completed by dredging and maintaining the internal structure of the sewage pipeline through the protective components.

[0027] According to an embodiment of the present invention, it further includes: a protective adhesive layer 6, which is disposed on the inner wall surface of the mounting base 2 and adheres to the bottom surface of the sewage pipe body 4.

[0028] In related technologies, the sewage pipe body 4 is easily damaged by impact when it is installed on the mounting base 2. In this embodiment of the invention, the protective adhesive layer 6 reduces the impact on the sewage pipe body 4 during the placement process and improves the protection of the sewage pipe body 4 during installation.

[0029] According to an embodiment of the present invention, the system further includes: a plurality of fixing holes 7 formed on the main body 4 of the sewage pipe; a plurality of support columns 8 respectively disposed in each fixing hole 7, with their top ends fixedly connected to the bottom surface of the corresponding limiting arc frame 3 and their bottom ends fixedly connected to the top surface of the drive rail 5.

[0030] In related technologies, drive rails are often placed at the bottom of pipes for ease of installation. However, once water flows inside the pipe body, the drive rails will suffer long-term corrosion. In this embodiment of the invention, the drive rail 5 is fixedly connected to the support column 8, so that the drive rail 5 is installed at the top of the sewage pipe body 4. This ensures that when water flows inside the sewage pipe body 4, the drive rail 5 is mostly above the water level, reducing corrosion of the drive rail 5 during sewage flow.

[0031] According to an embodiment of the present invention, the protection component includes: a connecting rod 9, one end of which is rotatably connected to the tunneling frame 10 and the other end of which is rotatably connected to the maintenance frame 11; a tunneling component, installed on the tunneling frame 10, for clearing the silt inside the sewage pipe body 4; a maintenance component, installed on the maintenance frame 11, for carrying the cleared silt out of the sewage pipe body 4; and a traveling component, respectively disposed on the tunneling frame 10 and the maintenance frame 11, and slidably connected to the drive rail 5.

[0032] In related technologies, underground pipelines are very long, making it difficult to perform flaw detection and maintenance on the entire underground pipeline. If cracks appear in the underground pipeline, sewage inside the underground pipeline will seep out, causing pollution to the external underground environment. In this embodiment of the invention, a tunneling component and a maintenance component are set inside the sewage pipeline. The tunneling component, driven by the traveling component, drills into the sewage sludge to ensure the normal operation of the maintenance component. When the sewage pipeline is blocked, the tunneling frame 10 can clear the blockage through the tunneling component to ensure normal sewage flow. Then, the traveling component drives the maintenance frame 11 forward to ensure that the maintenance component can carry the cleared sludge out of the sewage pipeline body 4, reducing the accumulation of sludge inside the sewage pipeline body 4.

[0033] According to an embodiment of the present invention, the walking assembly includes: a connecting frame 12, which is fixed to the top of the tunneling frame 10 and the maintenance frame 11 respectively; a limiting groove 13, which is symmetrically arranged on the left and right sides of the connecting frame 12; a limiting block 15, which is symmetrically arranged on the bottom surface of the drive rail 5 and is used to limit the engagement with the limiting groove 13; a sliding wheel 14, which is arranged in the limiting groove 13 on both sides respectively, and the wheel surface is in contact with the upper surface of the limiting block 15; a traveling wheel 16, which is rotatably connected to the tunneling frame 10 and the maintenance frame 11 respectively, and the wheel surface is in contact with the bottom surface of the drive rail 5; and a drive motor 17, which is arranged in the tunneling frame 10 and the maintenance frame 11 respectively, and is coaxially connected to the corresponding traveling wheel 16.

[0034] In this embodiment of the invention, the drive motor 17 drives the travel wheel 16 to rotate, and the travel wheel 16 drives the entire tunneling frame 10 and maintenance frame 11 to move within the sewage pipe body 4.

[0035] According to an embodiment of the present invention, the tunneling assembly includes: a tunneling drill bit 18, mounted on the tunneling frame 10; a tunneling motor 19, located inside the tunneling frame 10, with its output shaft coaxially connected to the tunneling drill bit 18; two cleaning nozzles 20, mounted on the tunneling frame 10, both spraying towards the tunneling drill bit 18; a water storage chamber 21, located inside the tunneling frame 10, for providing cleaning water to the two cleaning nozzles 20; a water pump 22, fixedly connected inside the water storage chamber 21, with its output end connected to the two cleaning nozzles 20 via a pipe; a water suction pipe 23, one end fixedly connected to the input end of the water pump 22, and the other end extending to the bottom of the water storage chamber 21; and a control module connected to the tunneling motor 19 and the cleaning nozzles 20, which controls the operation when the sludge coverage rate C in the sewage pipe body 4 is... m Greater than the preset silt coverage threshold C t When the control module starts the tunneling motor 19 to drive the tunneling drill bit 18 into the cleaning mode, it also starts the cleaning nozzle 20. When the silt coverage rate C m Below the safe value C sWhen this happens, the control module stops the tunneling motor 19 and the cleaning nozzle 20.

[0036] In this embodiment of the invention, the tunneling motor 19 drives the tunneling drill bit 18 to rotate, so that the tunneling drill bit 18 can clear the silt and debris blocking the sewage pipe body 4. Then, the cleaning nozzle 20 sprays water to clean the tunneling drill bit 18, reducing the debris in the gaps of the tunneling drill bit 18 and maintaining the tunneling capacity. At the same time, the control module controls the opening and closing of the tunneling motor 19 and the cleaning nozzle 20, so that the tunneling component can work according to the internal silt coverage, thereby improving the working efficiency of the tunneling component.

[0037] According to an embodiment of the present invention, the maintenance component includes: a plurality of panoramic probes 24, fixedly connected to the maintenance frame 11, for periodically acquiring images inside the sewage pipe body 4; a supplementary light 25, fixedly connected to the maintenance frame 11, for enabling the plurality of panoramic probes 24 to operate in a dark environment; and a monitoring module, connected to the plurality of panoramic probes 24, for real-time monitoring of the sludge coverage rate C. m The monitoring module converts the images acquired by the multiple panoramic probes 24 to grayscale according to the following formula: I grey = 0.299·R + 0.587·G + 0.114·B, where, I grey This is the grayscale image matrix of the image, where R, G, and B represent the red, green, and blue channels of the image, respectively. The monitoring module performs smoothing processing on the image based on this grayscale image matrix. Among them, I smooth (x,y) represents the smoothed grayscale image, where x and y represent the horizontal and vertical coordinates of the target pixel in the image matrix. G(i,j) is the Gaussian kernel function, representing the weights of the Gaussian smoothing filter. i and j represent the local coordinates within the Gaussian kernel function, used to specify the offset of pixels adjacent to the target pixel. k is the Gaussian kernel radius, i.e., the range of adjacent pixels participating in the smoothing operation. Based on the smoothed grayscale image and the grayscale threshold T, the monitoring module determines the silt region. Among them, I bin (x,y) represents the segmented binary image matrix, where 1 represents a silt area and 0 represents a non-silt area; the monitoring module calculates the silt coverage rate C based on this binary image matrix. m : Wherein, N is the total number of image pixels; the wear-resistant airbag 26 is fixedly connected to the maintenance frame 11; the air pump 27 is located inside the maintenance frame 11, with its input end connected to the wear-resistant airbag 26 and its suction end extending outside the maintenance frame 11.

[0038] This invention utilizes multiple panoramic probes 24 to facilitate maintenance personnel's inspection of the interior of the sewage pipe body 4, improving flaw detection capabilities and facilitating maintenance. Supplemental lighting 25 illuminates the panoramic probes 24, maintaining normal operation of the flaw detection process. An air pump 27 inflates the wear-resistant airbags 26, causing them to swell and adhere to the bottom inner wall of the sewage pipe body 4. A walking assembly then cleans the bottom inner wall of the sewage pipe body 4. Simultaneously, the monitoring module processes the images from the panoramic probes 24, performing grayscale and smoothing to calculate the silt coverage rate at a given acquisition time. This information is then transmitted to the control module to control the operation of the tunneling assembly.

[0039] According to an embodiment of the present invention, the system further includes: a plurality of pressure-bearing columns 32, the top ends of which are fixedly connected to the plurality of mounting bases 2; a plurality of damping grooves 28, which are formed inside the base 1 and whose width corresponds to the plurality of pressure-bearing columns 32; a plurality of pressure-bearing plates 30, which are sleeved on the middle of the plurality of pressure-bearing columns 32; a plurality of pressure-bearing grooves 29, which are formed on the middle of the plurality of damping grooves 28 and whose width corresponds to the plurality of pressure-bearing plates 30; and a plurality of high-strength springs 31, one end of which is fixedly connected to the bottom surface of the plurality of pressure-bearing plates 30 and the other end of which is fixedly connected to the bottom of the plurality of pressure-bearing grooves 29.

[0040] In related technologies, road surface undulations such as vehicle bumps can damage the structure of sewage pipes. In this embodiment of the invention, the combination of the pressure column 32 and the high-strength spring 31 reduces the impact of vehicle bumps and vibrations and chassis changes on the main body of the sewage pipe 4, thereby reducing the occurrence of cracks, damage and misalignment of the sewage pipe and improving its protection capabilities.

[0041] According to an embodiment of the present invention, a protective sleeve 33 is provided on the outer side of the connecting rod 9.

[0042] In related technologies, the connecting rod is easily corroded in the humid environment inside the sewage pipe body 4. In this embodiment of the invention, the connecting rod 9 is protected by a protective sleeve 33 to reduce corrosion of the connecting rod 9.

[0043] The invention has the following effects:

[0044] (1) The tunneling component, driven by the traveling component, drills through the sewage sludge to ensure the normal operation of the protection component. When the sewage pipe is blocked, the tunneling frame can clear the blockage through the tunneling component to ensure the normal flow of sewage.

[0045] (2) The wear-resistant airbag is inflated by an air pump, so that the wear-resistant airbag swells and fits against the bottom inner wall of the sewage pipe body. Then, the bottom inner wall of the sewage pipe body is cleaned by the walking component.

[0046] (3) Multiple panoramic probes facilitate maintenance personnel to inspect the inside of the sewage pipeline, improve the flaw detection capability, facilitate personnel to maintain the sewage pipeline, and supplement the panoramic probes with supplementary lighting to maintain the normal operation of the flaw detection work.

[0047] (4) By combining the pressure column with the high-strength spring, the impact of vehicle bumps and vibrations on the road surface and chassis changes on the main body of the sewage pipeline is reduced, the occurrence of cracks, damage and misalignment of the sewage pipeline is reduced, the protection capability is improved, and the impact of traffic load on the sewage pipeline is reduced.

[0048] (5) The sewage pipeline is externally supported and protected by multiple limiting arc frames, which improves the structural strength and load-bearing capacity of the sewage pipeline. Furthermore, the increased strength of the underground support structure of the road also further enhances the traffic load capacity of the road.

[0049] The above embodiments are merely examples to clearly illustrate the present invention and are not intended to limit the implementation of the invention. Those skilled in the art can make other variations or modifications based on the following description, and these variations, modifications, substitutions, and alterations arising from the principles and spirit of the present invention still fall within the protection scope of the present invention.
