Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary technology for silt detection, specifically a silt detection structure for rainwater pipes. Background Technology
[0002] With the acceleration of urbanization, stormwater pipes, as a core component of urban drainage systems, are directly related to urban flood control, water quality, and road traffic safety. However, during the collection and transportation of rainwater, it carries solid particles such as surface sediment, fallen leaves, and household waste debris, which accumulate over time to form pipe silt. This silt not only encroaches on the pipe's cross-section, reducing drainage capacity and inducing urban flooding, but it may also be washed into natural water bodies during rainfall, causing water accumulation and pollution. Simultaneously, it accelerates corrosion of the pipe's inner wall, shortens the pipe's lifespan, and increases maintenance costs. Therefore, it is necessary to regularly monitor the silt condition using auxiliary testing components, such as measuring its accumulation thickness and extracting samples.
[0003] In response, Chinese patent application number CN202421512848.8 discloses a rainwater pipe silt detection structure, including a structural body and a rainwater pipe body. The structural body is installed on the top of the rainwater pipe body through a limiting mechanism. The structural body includes a positioning cover, and a detection tube is movably installed at the center of the positioning cover.
[0004] However, existing detection auxiliary structures are inconvenient for providing stable support, insertion measurement, and sample extraction assistance as needed for detection, which affects operational detection efficiency.
[0005] Therefore, in order to solve the above problems, a silt detection structure for rainwater pipes is proposed. Utility Model Content

[0038] Working principle: During assembly and use, the support frame 110 and inner support plate 111 are mounted on the outside of the rainwater pipe inspection area. Then, with the cooperation of the screw pin 121 and support ball 122, auxiliary adjustment is made through the inner groove 124, so that the support frame 110 and inner support plate 111 support the detection tube 100 relatively vertically downwards. With the cooperation of the bubble assembly 140, this facilitates observation, similar to the relative leveling operation when operating surveying instruments. This ensures that the detection tube 100 is relatively vertically downwards when inserted later, facilitating... To ensure accuracy when detecting sludge thickness, the side slide bar 150 and spring 153 work together to press the top cover 101 to drive the detection tube 100 to insert downwards. With the cooperation of the bottom insertion tip 102 and the scale mark 103, the sludge thickness is measured. At the same time, with the cooperation of the bottom of the bottom insertion tip 102 and the discharge port 104, the auxiliary winch 130 is rotated by the upper handle 132 to lift the sludge to the top and discharge it through the discharge port 104 for sampling. This makes the operation more convenient. The operation ends here.
