Abstract
Description
Technical Field
[0001] The invention relates to the field of drainage pipeline detection, and more specifically to a device for detecting defects in urban drainage pipelines. Background Art
[0002] Urban drainage pipes are important hubs for urban wastewater discharge. Urban drainage pipes need to be regularly inspected for defects to prevent blockage or damage.
[0003] The traditional urban drainage pipe inspection method on the market is to run a detection vehicle in the pipe and use the camera carried by the detection vehicle to check and detect internal defects in the drainage pipe. Since the drainage pipe is a channel for discharging sewage, a layer of sludge is easily attached to the inner wall of the drainage pipe. When the inner wall of the drainage pipe is attached with thick sludge, the camera of the detection vehicle is not easy to observe the pipe defects covered by sludge, and the detection vehicle is easy to overturn in the circular pipe, resulting in drainage pipe defects. It is difficult to detect in time, causing greater losses later. Summary of the invention
[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a device for detecting defects in urban drainage pipes, which can prevent the detection device from tipping over in the drainage pipe through a support component, and the scraping component can scrape away the sludge attached to the inner wall of the drainage pipe, so that the visual inspection module can detect pipe defects originally covered by sludge.
[0005] To solve the above problems, the present invention adopts the following technical solutions.
[0006] The device for checking and detecting defects in urban drainage pipes is applied to drainage pipes to be inspected, and is characterized in that it includes a screw, the end of which is fixedly connected to a visual inspection module for obtaining an image of the inside of the pipe, a power component, a scraping component and a support component are threadedly sleeved on the screw, the outer ends of the support component and the power component are in rotational contact with the inner wall of the drainage pipe, the power component is used to drive the screw to move along the axis of the drainage pipe under the support of the support component; the outer end of the scraping component is in sliding contact with the inner wall of the drainage pipe, and the scraping component is used to scrape off dirt on the inner wall of the drainage pipe.
[0007] Compared with the prior art, the present invention using the above technical solution has the following beneficial effects: The present invention provides a visual detection module, a support component, a power component and a scraping component. The visual detection module, the support component, the power component and the scraping component are all sleeved on a screw. The power component can drive the detection device to move inside the drainage pipe along the axis of the drainage pipe. With the support of the support component, the detection device is prevented from tipping over in the drainage pipe, and the scraping component scrapes away the sludge attached to the inner wall of the drainage pipe, so that the visual detection module can detect pipe defects originally covered by sludge, thereby increasing the detection efficiency.
[0008] Preferably, a further technical solution of the present invention is: The support assembly includes a disc, which is threadedly sleeved on a screw rod, a support block is fixedly connected to the front side of the disc, a plurality of grooves are radially opened on the support block, a rotating plate is rotatably arranged on the disc at the outer end of each groove, the inner end of the rotating plate is elastically connected to the groove, a rotating wheel is rotatably arranged on the outer end of the rotating plate, and the rotating wheel is used to contact the inner wall of the drainage pipe. Through the above structure, the support assembly of the present invention can be self-adjusted to be suitable for drainage pipes of different diameters, and stably supported inside the drainage pipe.
[0009] The rotating plate includes a limit plate and a pressure plate, a rotating frame is fixed at the outer end of each groove, a rotating rod is rotatably connected between the two rotating frames, one end of the limit plate and the pressure plate is fixed to the rotating rod, and the front sides of the limit plate and the pressure plate form an obtuse angle, the other end of the limit plate is rotatably connected to the rotating wheel, and the other end of the pressure plate is elastically connected to the front inner wall of the groove. Through the above structure, when the outer end of the limit plate is squeezed and contracted by the pipeline, the limit plate drives the pressure plate to rotate based on the rotating rod, and the pressure plate is supported under the action of the elastic force of the pressure plate, so that the rotating wheel at the outer end of the limit plate can abut against the inner wall of the drainage pipe.
[0010] A square plate is fixed on the inner wall of the front part of the groove, a push rod is inserted in the middle of the square plate, a clamp ring is fixedly connected to the end of the push rod away from the square plate, the clamp ring is fixed to the inner end of the pressure plate, a first compression spring is arranged on the movable sleeve of the push rod, and a first compression spring is arranged on the movable sleeve of the push rod between the square plate and the clamp ring. The first compression spring pulls the inner end of the front side of the pressure plate, so that the outer end of the limit plate has a tendency to stretch outward, thereby ensuring that the rotating wheel at the outer end of the limit plate always abuts against the inner wall of the drainage pipe.
[0011] The power assembly includes a card block, which is threadedly sleeved on the screw rod, and a rotating module is arranged on the outer circumference of the card block, and the axial direction of the rotating module is perpendicular to the axial direction of the screw rod. At least two rubber blocks are fixedly connected to the outer side of the rotating module at equal angles, and the rubber blocks are used to contact the inner wall of the drainage pipe. The rotating module drives the rubber block to rotate, so that the rubber block rubs against the inner wall of the drainage pipe, and the detection device of the present invention is driven to move inside the drainage pipe under the action of friction.
[0012] The scraping assembly includes a columnar block, a plurality of vertical rods and a housing, wherein the columnar block is threadedly sleeved on the screw rod, each housing is radially fixed on the outer wall of the columnar block, the inner end of the vertical rod is elastically inserted into the housing, and the outer end of the vertical rod is connected to a scraper, which is used to scrape off dirt on the inner wall of the drainage pipe, so that the sludge attached to the inner wall of the pipe can be scraped off, and the pipe defects are prevented from being blocked by the sludge. Through the above structure, the scraper is always kept in contact with the inner wall of the drainage pipe, thereby increasing the scraping efficiency.
[0013] An opening for inserting a vertical rod is provided at the outer end of the shell, and a rectangular protrusion is fixed to the inner end of the vertical rod located inside the shell. The size of the rectangular protrusion is larger than the size of the opening to prevent the vertical rod from detaching from the shell.
[0014] There are two groups of columnar blocks on the shell, and the shells of each group are arranged equidistantly in the radial direction, and the shells of the two groups are arranged crosswise in the axial direction, so that the sludge attached to the inner wall of the pipeline can be evenly scraped off.
