[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] Reference will now be made in detail to various embodiments of the present 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 of the exemplary embodiments shown in the drawings with reference to their positions.

An embodiment of the present invention provides a road underground sewage pipe protection device, as shown in the figure, comprising a base 1, a plurality of mounting seats 2 arranged on the base 1, and a sewage pipe body 4 arranged on the plurality of mounting seats 2, and also comprising: a plurality of limiting arc frames 3, rotatably connected to the plurality of mounting seats 2, for limiting the sewage pipe body 4; a driving track 5, located in the sewage pipe body 4, fixedly connected to the plurality of limiting arc frames 3; a protection component, slidably connected to the driving track 5, for clearing the sewage pipe body 4.

[0026] In the related art, the pipes under the road are in direct contact with the soil and bear pressure, but under the action of vehicle load, especially under heavy load or overload conditions, the road surface often suffers from diseases at an early stage, which will affect the sewage pipes under the road, and easily cause cracks, breakage and pipe dislocation in the sewage pipes. The sewage pipe body 4 can be laid on multiple mounting seats 2, so that the sewage pipe body 4 is isolated from the ground through the mounting seats 2, and the sewage pipe is prevented from being in long-term contact with the water that infiltrates and accumulates underground, thereby reducing the corrosion of the sewage pipe by underground seepage, and the sewage pipe body 4 is further fixed by the limiting arc frame 3, and then used as an external protective component to protect the sewage pipe body 4, thereby improving the protection capability of the outside of the sewage pipe body 4, and then the inside of the sewage pipe body 4 is cleared and maintained by the protective component to complete the protection capability of the inside of the sewage pipe body 4.

[0027] According to an embodiment of the present invention, it further includes: a protective rubber layer 6, which is arranged on the inner wall surface of the mounting seat 2 and fits with the bottom surface of the sewage pipe body 4.

[0028] In the related art, when the sewage pipe body 4 is installed on the mounting seat 2, it is easy to be damaged by impact force. In the embodiment of the present invention, the protective rubber layer 6 is placed during the placement of the sewage pipe body 4 to reduce the impact on the sewage pipe body 4 and improve the protection capability of the sewage pipe body 4 during installation.

[0029] According to an embodiment of the present invention, it also includes: a plurality of fixing holes 7, which are opened on the sewage pipe body 4; a plurality of support columns 8, which are respectively arranged in each of the fixing holes 7, and the top ends are respectively fixedly connected to the bottom surfaces of the corresponding limiting arc frames 3, and the bottom ends are respectively fixedly connected to the top surfaces of the driving rails 5.

[0030] In the related art, the driving rail is often arranged at the bottom of the pipe for easy installation. However, once water flows inside the pipe body, the driving rail will be corroded for a long time. In the embodiment of the present invention, the driving rail 5 is fixedly connected to the support column 8, so that the driving rail 5 is installed on the top of the sewage pipe body 4. When water flows inside the sewage pipe body 4, the driving rail 5 is above the water level in most cases, thereby reducing the corrosion of the driving rail 5 when sewage flows.

[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 excavation frame 10, and the other end of which is rotatably connected to the maintenance frame 11; an excavation component, installed on the excavation frame 10, for clearing the silt in the sewage pipe body 4; a maintenance component, installed on the maintenance frame 11, for bringing the cleared silt out of the sewage pipe body 4; a walking component, respectively arranged on the excavation frame 10 and the maintenance frame 11, and slidably connected to the drive rail 5.

[0032] In the related art, the length of the underground pipeline is very long, and it is difficult to perform flaw detection and maintenance on the entire underground pipeline. If cracks appear in the underground pipeline, the sewage in the underground pipeline will seep out and pollute the external underground environment. In the embodiment of the present invention, a tunneling component and a maintenance component are arranged inside the sewage pipeline. The tunneling component drills in the sewage sludge driven by the walking component to ensure the normal operation of the protection component. When the sewage pipeline is blocked, the tunneling frame 10 can clear the blockage through the tunneling component to ensure the normal circulation of sewage, and then drive the maintenance frame 11 forward through the walking component to ensure that the maintenance component can bring the cleared sludge out of the sewage pipe body 4 to reduce the accumulation of sludge inside the sewage pipe body 4.

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

[0034] In the embodiment of the present invention, the driving motor 17 drives the traveling wheel 16 to rotate, so that the traveling wheel 16 drives the entire excavation frame 10 and the maintenance frame 11 to move in the sewage pipe body 4.

[0036] In the embodiment of the present invention, the tunneling motor 19 drives the tunneling drill bit 18 to rotate, so that the tunneling drill bit 18 clears the silt and debris blocked in the sewage pipe body 4, and then the cleaning nozzle 20 sprays water to clean the tunneling drill bit 18, thereby reducing the debris in the gap of the tunneling drill bit 18 and maintaining the tunneling capability. At the same time, a control module is used to control 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 rate, 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 regularly collecting images in the sewage pipe body 4; a fill light 25, fixedly connected to the maintenance frame 11, for enabling the plurality of panoramic probes 24 to operate in a dark environment; a monitoring module, connected to the plurality of panoramic probes 24, for real-time monitoring of the sludge coverage C m , wherein: the monitoring module grayscales the images collected by the multiple panoramic probes 24 according to the following formula: grey =0.299·R+0.587·G+0.114·B, where I grey is the grayscale image matrix of the image, R, G, and B are the red, green, and blue channels of the image respectively; the monitoring module performs smoothing on the image according to the grayscale image matrix: Among them, I smooth (x, y) is the smoothed grayscale image, x, y represent the horizontal and vertical coordinates of the target pixel in the image matrix, G(i, j) is the Gaussian kernel function, which represents the weight of the Gaussian smoothing filter, i, j represent the local coordinates in the Gaussian kernel function, which are used to specify the pixel offset adjacent to the target pixel, and k is the Gaussian kernel radius, that is, the range of adjacent pixels involved in the smoothing operation; the monitoring module determines the silt area based on the smoothed grayscale image and the grayscale threshold T: Among them, I bin (x, y) represents the binary image matrix after segmentation, 1 represents the silt area, and 0 represents the non-silt area; the monitoring module calculates the silt coverage rate C according to the 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 in the maintenance frame 11, the input end is connected to the wear-resistant airbag 26, and the suction end extends to the outside of the maintenance frame 11.

[0038] The embodiment of the present invention uses multiple panoramic probes 24 to facilitate maintenance personnel to explore the inside of the sewage pipe body 4, improve the flaw detection capability, and facilitate personnel to maintain the sewage pipe body 4. The panoramic probe 24 is supplemented with light by the fill light 25 to maintain the normal operation of the flaw detection work, and then the wear-resistant airbag 26 is inflated by the air pump 27, so that the wear-resistant airbag 26 swells and fits the bottom inner wall of the sewage pipe body 4, and then the bottom inner wall of the sewage pipe body 4 is driven by the walking component to clean. At the same time, the monitoring module can grayscale and smooth the image according to the image of the panoramic probe 24, and then calculate the silt coverage rate at a certain acquisition time, and finally transmit the information to the control module to control the work of the excavation component.

[0039] According to an embodiment of the present invention, it also includes: a plurality of pressure columns 32, the top ends of which are fixedly connected to the plurality of mounting seats 2; a plurality of shock-absorbing grooves 28, which are opened in the base 1 and have a width corresponding to the plurality of pressure columns 32; a plurality of pressure plates 30, which are sleeved on the middle parts of the plurality of pressure columns 32; a plurality of pressure grooves 29, which are opened in the middle parts of the plurality of shock-absorbing grooves 28 and have a width corresponding to the plurality of pressure 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 plates 30, and the other end of which is fixedly connected to the bottom of the plurality of pressure grooves 29.

[0040] In the related art, the ups and downs of the road surface such as vehicle bumps may damage the sewage pipe structure.

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

[0042] In the related art, the link rod is exposed to the humid environment in the sewage pipe body 4 and is easily corroded. In the embodiment of the present invention, the link rod 9 is protected by a protective tube cover 33 to reduce the corrosion of the link rod 9.
