Description

Technical Field

[0001] This utility model relates to the field of drainage ditch technology, specifically a double-layer drainage ditch. Background Technology

[0002] The prior art discloses a double-layer drainage ditch for land remediation, authorized by publication number CN217027372U, which relates to the field of drainage ditch technology. It includes a drainage frame with a filter assembly inside. Connecting components are installed between the filter assemblies. By setting up a drain plate and a filter plate, double-layer filtration of debris is achieved. The staggered positions of the drain holes and filter holes prevent debris from falling vertically into the filter holes, reducing the likelihood of debris falling onto the bottom of the drainage frame and causing blockage. The corner grooves facilitate the placement of the drain plate and filter plate. When debris clogs the drain plate and filter plate, turning the handle rotates the first connecting column, causing the slider to rotate from the vertical groove to the horizontal groove. Pulling the drain plate upwards simultaneously pulls out both the drain plate and filter plate for cleaning. The connecting ring and limiting groove prevent the first connecting column from falling out of the connecting hole and also facilitate rotation.

[0003] However, it has been found in use that the existing double-layer drainage ditches often use screw-fixed or unfixed installation methods for their drain covers. Screw-fixed drain covers are difficult to disassemble, making it difficult to clean debris from the filter plate. Unfixed drain covers are easy to lose or fall into the drainage ditch, causing a large amount of debris to enter the drainage ditch and cause blockage. Utility Model Content

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0036] like Figure 1-6As shown, a double-layer drainage ditch includes a first drainage channel 1, with ear plates 2 fixedly installed on both sides of the first drainage channel 1. A second drainage channel 3 is slidably installed inside the first drainage channel 1. A filter screen plate 4 is provided on the bottom inner wall of the second drainage channel 3. A drain cover plate 5 is provided on the top of the first drainage channel 1. The drain cover plate 5 has multiple water passage holes 6 penetrating through it. The drain cover plate 5 is slidably connected to the inner wall of the first drainage channel 1. Multiple slots 7 are provided on both sides of the inner wall of the first drainage channel 1. A locking rod 8 is slidably installed in the slots 7. Multiple chambers 9 are provided on the drain cover plate 5. A sliding plate 10 is slidably installed in each chamber 9. One end of the locking rod 8 extends into the corresponding chamber 9 and is fixed on the sliding plate 10. The top of the chamber 9... A rectangular through-slot 11 runs through the inner wall of the first drainage channel 1. A pull block 12 is slidably installed in the rectangular through-slot 11 and fixed to the top of the corresponding slide plate 10. Horizontal plates 13 are fixedly installed on both inner walls of the first drainage channel 1. The second drainage channel 3 contacts the tops of both horizontal plates 13. A simple locking structure facilitates quick installation and removal of the drain cover 5, making it easy to clean debris from the filter plate and effectively preventing the drain cover 5 from falling into the drainage ditch, ensuring unobstructed drainage. The second drainage channel 3 also includes multiple pull rods 14, which are slidably installed in the second drainage channel 3. A brush 15 is fixedly installed at the bottom of each pull rod 14, and the brush 15 contacts the top of the filter screen plate 4. The horizontal plates 13... Multiple vertical rods 16 slide through the upper part of the second drainage trough 3, and the vertical rods 16 are fixed to the bottom of the second drainage trough 3. This arrangement facilitates the quick collection and cleaning of debris on the filter screen plate 4. Multiple ground plugs are fixedly installed at the bottom of both the ear plate 2 and the first drainage trough 1. The ground plugs are evenly arranged to securely install the first drainage trough 1 in the ditch. Two clamping plates are fixedly installed at the bottom of the drain cover 5. The clamping plates are slidably connected to the inner wall of the second drainage trough 3. Multiple finger grooves are opened on the inner walls of both sides of the second drainage trough 3. The clamping plates are used to limit the position of the drain cover 5. A first water passage hole is penetrated through the bottom inner wall of the chamber 9. One side of the chamber 9... A first through hole is formed in the inner wall, through which the locking rod 8 slides. The first water passage hole prevents water accumulation in the chamber 9. A second through hole is formed in the slide plate 10, and a limiting rod is fixedly installed inside the chamber 9. The limiting rod slides through the second through hole, and a rubber damping sleeve is fixedly installed inside the second through hole. The rubber damping sleeve is slidably fitted onto the limiting rod. This design facilitates the limiting of the slide plate 10 and effectively prevents accidental movement. Two sliding grooves are formed on the inner walls of both sides of the second drainage groove 3. Limiting blocks are slidably installed in the sliding grooves and fixed to the pull rod 14. Multiple second water passage holes are formed in the pull rod 14. This design facilitates the limiting of the pull rod 14.A rectangular through-slot is formed on the bottom inner wall of the second drainage trough 3. The filter screen 4 is fixed within the rectangular through-slot. Multiple third through-holes are formed on the horizontal plate 13. The vertical rod 16 slides through the corresponding third through-holes. The third through-holes facilitate the limiting of the vertical rod 16.

[0037] The working principle of this utility model is as follows: In use, first dig a trench of suitable size on the ground, then install the first drainage trough 1 in the trench. Press the first drainage trough 1 so that the ground inserts at the bottom of the first drainage trough 1 and the ear plate 2 are inserted into the soil. Then, slide the second drainage trough 3 into the first drainage trough 1. The vertical rod 16 slides through the horizontal plate 13. Then, cover the first drainage trough 1 with the drain cover 5. Next, insert your finger into the rectangular through-slot 11 and pull the pull block 12, causing the pull block 12 to slide laterally within the rectangular through-slot 11. This causes the slide plate 10 to slide laterally within the chamber 9, causing the locking rod 8 to slide laterally into the corresponding locking slot 7, thus fixing the drain cover 5. When the ground is flooded, the water enters the second drainage trough 1 through multiple water passages 6 on the drain cover 5. In the drainage trough 3, the muddy water is filtered by the filter screen plate 4 and then collected at the bottom of the first drainage trough 1 and flows away. When it is necessary to clean the filter screen plate 4, the drain cover plate 5 can be opened to clean the debris. This setting facilitates the quick installation and removal of the drain cover plate 5, making it easier to clean the debris on the filter plate, and effectively prevents the drain cover plate 5 from falling into the drainage ditch, ensuring the drainage ditch is unobstructed. After opening the drain cover plate 5, pull the lever 14, causing the lever 14 to slide laterally in the second drainage trough 3, which causes the brush 15 to move laterally. The debris on the filter screen plate 4 is cleaned and collected by the brush, and then the collected debris can be cleaned. This setting facilitates the quick cleaning and collection of debris on the filter screen plate 4, making it easy to clean the debris quickly.
