[0018] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0019] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention discloses a road drainage ditch filtration structure, including a drainage ditch 1 and a cover plate 2. The cover plate 2 is disposed on the drainage ditch 1. The cover plate 2 has positioning openings on the left and right sides of the middle. Each positioning opening is provided with a positioning plate 3. The opposite side of the positioning plate 3 protrudes to form a positioning part 11. The inner side of the drainage ditch 1 is provided with a positioning groove 8 opposite to the positioning part 11. The positioning part 11 is inserted into the positioning groove 8. The cover plate 2 is provided with a groove between the positioning openings. The groove is provided with a handle 6 for pulling the positioning plate 3 inward.

[0022] In this embodiment, both ends of the groove are provided with wiring holes that communicate with the positioning port. Each wiring hole contains a rubber ring. Both ends of the handle 6 are equipped with steel wire ropes. The other end of each steel wire rope passes through the rubber ring and is installed on the positioning plate 3. A rubber sleeve 4 and a first compression spring are fitted on the section of the steel wire rope located inside the positioning port. The first compression spring is located inside the rubber sleeve 4. One end of the first compression spring and the rubber sleeve 4 are installed on the positioning plate 3, and the other end is installed on the inner wall of the positioning port.

[0023] In this embodiment, multiple metal cylinders 7 are embedded on the end face of the drainage channel 1. Positioning rods 9 are installed on the inner side of the cover plate 2 opposite to the metal cylinders 7. The positioning rods 9 are all inserted into the metal cylinders 7 and are all equipped with second compression springs 10. The other end of the second compression springs 10 is in contact with the inner wall of the metal cylinders 7 and the second compression springs 10 are all in a compressed state.

[0024] In this embodiment, a sliding groove 5 is provided on both sides of the positioning port, and a slider is installed on both sides of the positioning plate 3 opposite to the sliding groove 5. The slider is slidably disposed in the sliding groove 5. The positioning plate can be positioned by the sliding groove and the slider, so that the positioning plate can only move back and forth along the sliding groove.

[0025] In this embodiment, the cover plate 2 is provided with multiple filter ports, so that rainwater from the outside can enter the drainage ditch through the filter ports, while garbage from the outside is intercepted by the filter ports.

[0026] In this embodiment, the bottom surface of the positioning part 11 is inclined to form a guide part, so that the positioning plate can move inward after the guide part on the positioning plate is pressed.

[0027] When disassembly is required, you can directly hold the handle and pull it upwards. The movement of the handle drives the steel wire rope, which pulls the positioning plates on both sides inwards, causing the positioning parts on the positioning plates to disengage from the positioning grooves. After the positioning parts are no longer engaged with the positioning grooves, the cover plate can be lifted upwards by the rebound of the second compression spring, causing the cover plate to be misaligned with the adjacent cover plate, which facilitates disassembly without the need for a pry bar and avoids damage to the cover plate and drainage channel.

[0028] During installation, the positioning rod on the cover plate can press down directly onto the metal cylinder. After the guide part of the positioning section is squeezed against the end face of the drainage channel, the positioning plate can automatically move inward, allowing it to smoothly enter the interior of the drainage channel. After the cover plate comes into contact with the drainage channel, the positioning part on the positioning plate is aligned with the positioning groove. The rebound of the first compression spring pushes the positioning plate outward, causing the positioning part on the positioning plate to automatically insert into the positioning groove. The cover plate is fixed by the insertion method, preventing it from tilting up.

[0029] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
