[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A road drainage cover includes a drainage channel 1, with an installation groove 11 at the top and a slot 12 on the surface of the installation groove 11. A cover body 2 is movably connected inside the installation groove 11. A sliding groove 21 is provided inside the cover body 2, and a sliding groove 22 is provided at the top of the sliding groove 21. A receiving groove 23 is provided at the top of the cover body 2, and a sliding groove 24 is provided on the side surface of the cover body 2. A filter structure 3 is provided at the bottom of the cover body 2. The filter structure 3 includes a first hanging ear 31, a connecting rod 32 movably connected to the bottom of the first hanging ear 31, and a second hanging ear movably connected to the bottom of the connecting rod 32. 33. A collection box 34 is fixedly connected to the bottom of the second hanging ear 33. An installation structure 4 is provided inside the cover body 2. The installation structure 4 includes a sliding seat 41. A baffle 42 is fixedly connected to the surface of the sliding seat 41. A spring 43 is fixedly connected to one side of the baffle 42. An insert rod 46 is fixedly connected to the other side of the baffle 42. A rotating shaft 44 is fixedly connected to the top of the baffle 42. A pull rod 45 is rotatably connected to the surface of the rotating shaft 44. A sealing gasket 47 is inserted into the top of the second sliding groove 22 and the storage groove 23. The installation structure 4 is provided. During installation, pulling the pull rod 45 will drive the sliding seat 41 to move through the rotating shaft 44, thereby causing the baffle 42 to move. Moving the cover plate 2 within the first slide 21 compresses the spring 43, allowing the insert rod 46 to fully enter the third slide 24, making both sides of the cover plate body 2 flat. The cover plate body 2 is then lifted by the pull rod 45 and inserted into the mounting groove 11. Releasing the pull rod 45, the baffle 42 is moved under the action of the spring 43, causing one end of the insert rod 46 to insert into the slot 12 from the third slide 24, thus fixing the cover plate body 2 to the top of the drainage trough 1. Rotating the pull rod 45 causes it to enter the receiving groove 23, allowing the sealing gasket 47 to be inserted into the top of the second slide 22 and the receiving groove 23, thereby sealing the first slide 21 and the receiving groove 23 and preventing impurities from entering. The cover body 2 is designed to allow for easy installation and disassembly of debris while ensuring its stability. It includes a cover body 2 and a filter structure 3. The cover body 2 provides initial filtration of rainwater, blocking larger debris at the top. Rainwater then flows into the drainage trough 1 and is filtered by a collection box 34 to remove smaller impurities, preventing blockage of the drainage pipes. The collection box 34 can be removed along with the cover body 2. It is attached to the bottom of the cover body 2 via a connecting rod 32, facilitating easy removal, cleaning, and replacement. This design makes it convenient to use.

[0024] Furthermore, the first hanging ear 31 is fixedly connected to the bottom of the cover plate body 2, and the two ends of the connecting rod 32 are respectively hung in the first hanging ear 31 and the second hanging ear 33. The bottom of the collection box 34 is provided with a filter screen. The collection box 34 is hung on the bottom of the cover plate body 2 through the connecting rod 32, which makes it easy to remove, clean and replace the collection box 34, making it more convenient to use.

[0025] Furthermore, the sliding seat 41 and the baffle 42 are slidably connected in the slide groove 21. The two ends of the spring 43 are fixedly connected to the surface of the baffle 42 and the inner wall of the slide groove 21, respectively. Pulling the pull rod 45 causes the sliding seat 41 to move through the rotating shaft 44, thereby causing the baffle 42 to move in the slide groove 21, compressing the spring 43. Without external force, the baffle 42 and the sliding seat 41 are reset by the spring 43.

[0026] Furthermore, the pull rod 45 is L-shaped and has a rotatable structure at the top of the sliding seat 41. The pull rod 45 is slidably connected in the second slide groove 22, and the L-shaped pull rod 45 facilitates the lifting and movement of the cover plate body 2.

[0027] Furthermore, the pull rod 45 is rotatably connected to the storage groove 23. The inner wall of the storage groove 23 does not contact the side surface of the pull rod 45, which facilitates the rotation of the pull rod 45 in the storage groove 23 and makes it easy to rotate and remove the pull rod 45. The pull rod 45 can be rotatably stored in the storage groove 23, ensuring that the top of the cover plate body 2 is flat. The sealing gasket 47 is inserted into the top of the slide groove 22 and the storage groove 23 to seal the slide groove 21 and the storage groove 23, preventing foreign objects from entering.

[0028] Furthermore, the diameter of the insert rod 46 is equal to the inner diameter of the slot 12 and the slide groove 24. The insert rod 46 is inserted into the slot 12 and the slide groove 24. Through the cooperation between the insert rod 46 and the slot 12, the cover plate body 2 can be installed on the top of the drainage groove 1.

[0029] Furthermore, the height of the baffle 42 is greater than the height of the sliding seat 41. By cooperating with the storage groove 23, the rotation angle of the pull rod 45 is limited, so that it can only rotate 90 degrees outward from inside the storage groove 23.

[0030] Working principle: During installation, pulling the lever 45 moves the sliding seat 41 via the rotating shaft 44, causing the baffle 42 to move within the first slide groove 21, compressing the spring 43, and fully inserting the insertion rod 46 into the third slide groove 24, making both sides of the cover plate body 2 flat. The cover plate body 2 is then lifted by the lever 45 and inserted into the mounting groove 11. Releasing the lever 45, the baffle 42 is moved by the spring 43, causing one end of the insertion rod 46 to insert into the slot 12 from the third slide groove 24, thus fixing the cover plate body 2 to the top of the drainage trough 1. Rotating the lever 45 causes it to rotate into the receiving groove 23, inserting the sealing gasket 47 into the second slide groove 2. The top of the cover plate body 2 and the top of the storage groove 23 further seals the slide groove 21 and the storage groove 23 to prevent debris from entering. This ensures the stability of the cover plate body 2 during installation and facilitates the installation and disassembly of the cover plate body 2. The cover plate body 2 performs preliminary filtration of rainwater, blocking larger debris at the top of the cover plate body 2. After the rainwater flows into the drainage groove 1, it is filtered by the collection box 34 to remove smaller impurities from the rainwater, preventing impurities from clogging the drainage pipe and affecting drainage. When disassembling the cover plate body 2, the collection box 34 can be taken out together. The collection box 34 is hung at the bottom of the cover plate body 2 by the connecting rod 32, making it easy to remove, clean and replace the collection box 34.
