Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline detection, in particular to a rain and sewage pipeline non-excavation detection device. BACKGROUND

[0002] In urban infrastructure construction, the rain and sewage pipeline system is an important part of ensuring the normal operation of the city. However, due to long-term erosion by sewage, geological changes, external pressure and other factors, rain and sewage pipelines are prone to various problems and need to be detected regularly to solve internal problems in a timely manner.

[0003] At present, the traditional rain and sewage pipeline detection method is divided into two types: excavation detection and non-excavation detection. The excavation detection method needs to damage the road surface, affect traffic, increase costs, and has potential damage risk to surrounding facilities. Some existing non-excavation detection technologies, such as pipeline robot detection, avoid the disadvantages of excavating the road surface. However, due to the limited ability of existing pipeline robots to adapt to different pipe diameters, different shapes and internal obstacles in rain and sewage pipelines, when encountering internal bends, narrow areas or obstacles in the pipeline, the robot may not be able to pass smoothly, resulting in inaccurate detection results and failing to fully reflect the actual condition of the pipeline. CONTENT OF THE INVENTION

[0004] In order to solve the problem that the existing non-excavation detection equipment has poor self-adaptive ability and may not pass smoothly when encountering internal bends, narrow areas or obstacles in the pipeline, the present application provides a rain and sewage pipeline non-excavation detection device.

[0005] The rain and sewage pipeline non-excavation detection device provided by the present application adopts the following technical scheme:

[0006] A rain and sewage pipeline non-excavation detection device, comprising a detection device, a plurality of walking assemblies are arranged on the detection device, a universal joint is arranged between adjacent two walking assemblies, the walking assembly comprises a hinged seat, a plurality of support frames are hingedly arranged on the hinged seat, a power wheel is arranged on the support frame, a self-adaptive unit is further arranged on the hinged seat, the self-adaptive unit comprises a plurality of sliding sleeves moving axially along the support frame, and the sliding sleeves are respectively hingedly connected with the corresponding support frames.

[0007] Preferably, the support frame comprises a connecting rod hingedly connected to the power wheel, an inclined strut is hingedly connected to the connecting rod, and the inclined strut is hingedly connected to the sliding sleeve.

[0008] Preferably, the universal joint comprises a moving wheel arranged at the end of the connecting rod, a drive motor is drivingly arranged on the moving wheel, and the drive motor is arranged on the connecting rod.

[0009] Preferably, the self-adaptive unit comprises two connecting plates, the middle part of each of the two connecting plates is provided with a plurality of guide rods, the sliding sleeve is slidably arranged on the guide rods, and the side of the sliding sleeve away from the diagonal brace rod is provided with a spring, and the spring is slidably arranged on the guide rod.

[0010] Preferably, the hinge seat, the universal joint and the cable joint are connected with the corresponding connecting plates respectively.

[0011] To sum up, the application has the following beneficial technical effects:

[0012] Through the cooperation of the detection device, the walking assembly and the universal joint, the position of the power wheel is changed by adjusting the angle of the connecting rod. When walking in the pipeline, the angle of the connecting rod is adjusted by adjusting the angle of the connecting rod when one of the moving wheels is pressed to avoid obstacles, so that the diagonal brace rod pushes the sliding sleeve to press the spring. After passing the obstacle, the elastic force of the spring pushes the connecting rod to reset, and the walking is automatically attached to the inner wall of the pipeline, improving the accuracy and reliability of the detection. Compared with the prior art, it has the effect of strong self-adaptability. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0017] The following will be combined with the Figs. 1-3 The application will be further described in detail.

[0018] The application embodiment discloses a rain and sewage pipeline trenchless detection device. Referring to Figs. 1-3 A rain and sewage pipeline trenchless detection device mainly comprises a detection device 1, a walking assembly 2, a universal joint 3, a self-adaptive unit 204 and a cable joint 4, which realizes efficient and stable detection in the harsh environment of the rain and sewage pipeline.

[0019] Referring to Fig. 1The shell of the detection device 1 is made of high-strength and corrosion-resistant engineering transparent material through injection molding process, has good sealing and protection performance, and can be used in the harsh environment of rainwater and sewage pipelines for a long time. A high-definition camera is installed inside to ensure the normal operation of the detection device.

[0020] With reference to Fig. 2 The detection device 1 is provided with a plurality of walking assemblies 2 for driving the detection device 1 to move in the rainwater and sewage pipeline. The walking assembly 2 comprises a hinged seat 201 made of aluminum alloy through a mechanical processing process, which ensures the connection accuracy and reliability with other parts. A plurality of support frames 202 are hingedly arranged on the hinged seat 201. This hinged connection mode enables the support frame 202 to be flexibly adjusted in angle according to the internal conditions of the pipeline to adapt to different pipeline terrains.

[0021] With reference to Fig. 3 The support frame 202 comprises a connecting rod 2021 hingedly arranged on a power wheel 203 and an inclined strut 2022 hingedly connected with the connecting rod 2021. The connecting rod 2021 and the inclined strut 2022 are made of high-strength steel material, which is processed through forging and mechanical processing to ensure its strength and toughness. The power wheel 203 is made of rubber or polyurethane material, which has good wear resistance and grip to provide power for the movement of the detection device 1 in the pipeline.

[0022] With reference to Fig. 3The adaptive unit 204 is arranged on the hinged seat 201 and can automatically adjust the position of the support frame 202 according to the obstacles and the shape of the pipeline. The adaptive unit 204 comprises two connecting plates 2041 made of stainless steel through stamping or mechanical processing process. The middle part of each connecting plate 2041 is provided with a plurality of guide rods 2042 made of high-strength stainless steel rod and precisely processed to ensure that the sliding sleeve 2044 can smoothly slide thereon. The sliding sleeve 2044 is slidably arranged on the guide rod 2042, and the side of the sliding sleeve 2044 away from the inclined strut 2022 is provided with a spring 2043 which is slidably sleeved on the guide rod 2042. The spring 2043 is made of high-quality spring steel and is subjected to heat treatment and surface treatment, so as to have good elasticity and corrosion resistance. A flexible sleeve can be sleeved on the surface to prevent impurities from affecting the expansion and contraction of the spring 2043. The inclined strut 2022 is hinged to the sliding sleeve 2044. When obstacles appear in the pipeline or the shape of the pipeline changes, the expansion and contraction of the spring 2043 can drive the sliding sleeve 2044 to slide on the guide rod 2042, and then the position of the support frame 202 is adjusted through the inclined strut 2022, so as to ensure that the detection device 1 can stably walk in the pipeline and detect the inner wall of the pipeline. The sliding sleeve 2044 is made of copper alloy or engineering plastic and has good wear resistance and self-lubricating performance. In addition, the hinged seat 201, the universal joint 3 and the cable joint 4 are respectively connected with the corresponding connecting plates 2041. This connection mode enables the adaptive unit 204 to work cooperatively with other components to cope with complex pipeline environments.

[0023] With reference to Fig. 1 The universal joint 3 is arranged between the adjacent walking assemblies 2 and can realize flexible angle adjustment between the adjacent walking assemblies 2 to adapt to different terrains and curves in the pipeline. The universal joint 3 comprises a moving wheel 2031 arranged at the end of the connecting rod 2021, and a driving motor 2032 is arranged on the connecting rod 2021 and is in driving connection with the moving wheel 2031. The driving motor 2032 is a small, efficient and waterproof motor to ensure that it can work normally in a humid pipeline environment. The driving motor 2032 provides power for the moving wheel 2031 to roll in the pipeline and moves the adjacent walking assembly 2 through the universal joint 3. Each component of the universal joint 3 is made of high-strength steel material and is subjected to mechanical processing and heat treatment process to ensure its strength and rotation flexibility. An appropriate amount of lubricating oil is added at the rotating part of the universal joint or a self-lubricating material is used to reduce friction and wear and prolong the service life.

[0024] With reference to Fig. 2The cable joint 4 is made of waterproof and corrosion-resistant joint, which is used to connect the detection device 1 with the control equipment and data acquisition equipment on the ground. The connection ensures the stability and reliability of signal transmission, so that the operator can monitor the running state of the detection device 1 on the ground in real time and receive the feedback data and images. All connecting bolts, nuts and other connecting parts are made of stainless steel to ensure the firmness of the connection.

[0025] The implementation principle of the rain and sewage pipeline trenchless detection device according to the embodiment of the application is as follows:

[0026] After the detection device 1 enters the rain and sewage pipeline, the power wheel 203 and the moving wheel 2031 start to rotate under the driving of the driving motor 2032. The power wheel 203 provides the main forward driving force to push the detection device 1 to move forward in the pipeline. At the same time, the moving wheel 2031 is connected with the adjacent walking assembly 2 through the universal joint 3, which not only assists the forward movement of the detection device 1, but also adjusts the angle between the adjacent walking assemblies 2 through the flexible rotation of the universal joint 3 when encountering a curve or uneven pipeline surface, so that the detection device 1 can pass through smoothly.

[0027] The adaptive principle is as follows: when one of the moving wheels 2031 is pressed by an obstacle during walking in the pipeline, the angle of the connecting rod 2021 changes. The change of the angle of the connecting rod 2021 drives the inclined strut 2022 to move, the inclined strut 2022 pushes the sliding sleeve 2044 to slide along the guide rod 2042 and press the spring 2043. At this time, the position and angle of the whole support frame 202 are adjusted, so that the detection device 1 can avoid the obstacle.

[0028] After passing through the obstacle, the elastic force of the spring 2043 is released, the sliding sleeve 2044 is pushed to slide reversely along the guide rod 2042, the sliding sleeve 2044 drives the connecting rod 2021 to reset through the inclined strut 2022, so that the power wheel 203 and the moving wheel 2031 are automatically reattached to the inner wall of the pipeline. In this way, the detection device 1 can automatically adjust the posture in the rain and sewage pipeline with different diameters, different shapes and obstacles, walk stably and keep attached to the inner wall of the pipeline, so as to ensure the smooth progress of the detection work
