Description

Technical Field

[0001] The utility model belongs to the technical field of anti-blocking and dredging of cleaning openings of ground linear drainage ditches, and in particular relates to a large-area rapid drainage anti-blocking and dredging device. Background Art

[0002] With the continuous acceleration of urbanization and the popularization of outdoor landscapes, outdoor squares are increasingly appearing in urban public areas. The appearance of traditional drainage ditches is relatively ugly, which greatly affects the ground paving effect of squares and commercial corridors. In recent years, linear drainage ditches have gradually become popular, which not only solves the drainage problem, but also reduces the impact on the beauty and overall appearance of ground paving. However, with the increase in usage time, a large amount of ground garbage, such as paper scraps, plastic bags, fruit shells, etc., has accumulated inside the drainage ditch. These relatively small garbage passes through the drainage holes of the linear drainage ditch into the ditch, but because the openings on the linear drainage ditch are small and the surface layer cannot be excavated, the garbage in the ditch cannot be cleaned in time, resulting in blockage; in places with relatively high environmental requirements, flooding is often caused by blockage, resulting in a certain amount of economic losses; manual cleaning is time-consuming and labor-intensive and the effect is not good. Even if a cleaning port is set, it is difficult to clean the blockage in a short time.

[0003] In the patent document with publication number CN220266783U, "a kind of urban road drainage anti-blocking structure" is disclosed, which includes a first filter screen and a second filter screen, which are arranged in the drainage well and located below the grille; the first filter screen can move along the axial direction of the drainage well, when the first filter screen is blocked, the volume of water in the drainage well increases, the accumulated water presses down the first filter screen, and the first filter screen moves upward when it moves downward, and the accumulated water enters the drainage well through the second filter screen. The device has the following problems during use:

[0004] 1. The structure is relatively complex, and the transmission method needs to rely on the water pressure of the accumulated water. However, since the first filter and the second filter are both movable, leakage is prone to occur at the connection. Once leakage occurs, insufficient water pressure will easily lead to the inability to discharge debris.

[0005] 2. The structural stability is insufficient and requires regular inspection and maintenance, so the maintenance cost is high;

[0006] 3. The process of cleaning the deposited debris is rather cumbersome. After the first filter and the second filter are taken out, the debris deposited at the bottom needs to be salvaged, which is very inconvenient. Utility Model Content
