Description

Technical Field

[0001] The utility model relates to the field of pipeline detection equipment, in particular to an in-pipe detector for rainwater pipelines. Background Technique

[0002] Pipelines are an essential water supply and drainage tool in municipal engineering. Among them, there is a kind of rainwater pipeline, which is generally used to convey the road surface water into the surrounding rivers. After the rainwater pipeline drains water for a long time, the mud mixed in the rainwater is likely to accumulate in the pipeline, and it is necessary to regularly detect the thickness of the sludge inside the pipeline.

[0003] According to a rainwater pipeline sludge detection structure disclosed in a patent document with the existing publication number CN220620409U, it includes a through pipe. The upper surface of the through pipe is slidably connected with a mounting plate. The upper surface of the mounting plate is installed with a controller. The lower surface of the mounting plate is installed with a main body. The inner wall of the main body is installed with a detection rod. There are limiting structures on both sides of the mounting plate. The limiting structure includes two rotating frames. One side of the two rotating frames close to each other is fixedly connected with the mounting plate. When this technical solution is used, by setting the limiting structure, the effect of connecting and limiting between the mounting plate and the through pipe is achieved. The mounting plate is limited by the cooperation of the driving rod and the arc plate, so as to effectively prevent the mounting plate from shaking on the surface of the through pipe. And with the cooperation of the magnet and the iron block, the support plate can also be temporarily limited. For the above technical solution, although the device realizes the limitation of the support plate, it cannot quickly install this device on the pipeline for maintenance during the preliminary installation, and cannot quickly locate the surface of the sludge during the maintenance, which is inconvenient in use. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an in-pipe detector for rainwater pipelines to solve the problems raised in the above background technology. The structure of the utility model is novel. When in use, the movable plate is retracted into the opening. After the limiting plate and the movable plate are installed inside the pipeline, the movable seat is released. The movable seat is quickly in contact with the inner wall of the inspection pipe under the pulling of the pulling mechanism for limit fixation, which is convenient for the preliminary installation of the equipment. In addition, the pulling mechanism controls the movable rod to limit and fix inspection pipes with different diameters.

[0005] In order to achieve the above purpose, the utility model is realized by the following technical solutions: An in-pipe detector for rainwater pipelines includes a detector body. The detector body includes a pipeline. The top of the pipeline is fixedly provided with an inspection pipe. A detection component is movably installed inside the inspection pipe and the pipeline. The detection component includes a support plate. A slot is opened on the support plate. A movable seat is movably installed inside the slot. A pulling mechanism is fixedly installed between the movable seat and the slot. A fixed seat is fixedly installed on the inner wall of the slot. A support pipe is movably installed on the fixed seat.

[0006] Further, an activity column is movably installed inside the support pipe, and scale lines are fixedly installed on the activity column.

[0007] Further, an installation groove is formed in the movable seat, a movable rod is movably installed inside the installation groove, and a movable plate is fixed to one end of the movable rod.

[0008] Further, a limiting plate is fixed to one end of the support pipe, an opening is formed in the limiting plate, and the opening is matched with the movable plate.

[0009] Further, limiting grooves are formed in the inner wall of the slotted opening, limiting blocks are fixed to the side of the movable seat, and the limiting blocks are movably installed inside the limiting grooves.

[0010] Further, a sliding groove is formed in the inner wall of the support pipe, a sliding block is movably installed inside the sliding groove, one end of the sliding block is fixed to the activity column, a limiting ring is fixed to the inner wall of the support pipe, and one end of the activity column is matched with the limiting ring.

Specific embodiments

[0019] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: an in-rainwater-pipeline detector, including a detector body, the detector body includes a pipeline 1, an inspection pipe 2 is fixed on the top of the pipeline 1, a detection component 3 is movably installed inside the inspection pipe 2 and the pipeline 1, the detection component 3 includes a support plate 4, a slotted opening 5 is opened on the support plate 4, a movable seat 7 is movably installed inside the slotted opening 5, a tension mechanism 6 is fixedly installed between the movable seat 7 and the slotted opening 5, a fixed seat 18 is fixed on the inner wall of the slotted opening 5, a support pipe 9 is movably installed on the fixed seat 18, a movable column 10 is movably installed inside the support pipe 9, a scale line 11 is fixedly installed on the movable column 10, the tension mechanism 6 is a tension spring, and the movable seat 7 is quickly brought into contact with the inner wall of the inspection pipe 2 under the pull of the tension mechanism 6 for limit fixation.

[0021] In this embodiment, an installation groove 17 is formed in the movable seat 7, and a movable rod 8 is movably installed inside the installation groove 17. One end of the movable rod 8 is fixed with a movable plate 14. One end of the support pipe 9 is fixed with a limit plate 12. An opening 13 is formed in the limit plate 12, and the opening 13 is matched with the movable plate 14. A limit groove 15 is formed in the inner wall of the slot 5, and a limit block 16 is fixed on the side of the movable seat 7. The limit block 16 is movably installed inside the limit groove 15. A sliding groove 19 is formed in the inner wall of the support pipe 9, and a sliding block 20 is movably installed inside the sliding groove 19. One end of the sliding block 20 is fixed on the movable column 10. A limit ring 21 is fixed on the inner wall of the support pipe 9, and one end of the movable column 10 is matched with the limit ring 21. The limit ring 21 limits the position of the movable column 10. When the movable column 10 moves upward later, the limit ring 21 scrapes and cleans the silt on the surface of the movable column 10.

[0022] When the device is in use, the movable seat 7 is moved inside the slot 5 towards the fixed seat 18. The movable seat 7 drives the movable rod 8 to move, and the movable plate 14 on the movable rod 8 moves into the opening 13, reducing the overall width of the movable plate 14 and the limit plate 12, facilitating the installation of the limit plate 12 and the movable plate 14 inside the pipeline 1 through the inspection pipe 2. After being installed inside the inspection pipe 2, the movable seat 7 is released. The movable seat 7 quickly contacts the inner wall of the inspection pipe 2 on both sides under the pulling of the tension mechanism 6 for limit fixation, facilitating the rapid installation of the detection component 3. When in need of use, the movable rod 8 and the support pipe 9 are moved downward simultaneously. When the movable plate 14 and the limit plate 12 contact the surface of the silt, resistance is generated. The resistance limits the top of the silt. Then, the movable column 10 is pressed. The movable column 10 moves downward through the limit ring 21. The distance that the movable column 10 moves downward is observed through the scale line 11. When one end of the movable column 10 contacts the inner wall of the pipeline 1, it stops moving. After stopping, the thickness of the silt can be quickly understood. The cooperation of the movable plate 14 and the limit plate 12 increases the contact with the silt and avoids the error caused by too small a contact area entering the silt.
