[0029] Reference Figure 1-3This utility model provides an embodiment of a drainage structure that is easy to clean, including a drainage frame 1. A top frame 2 is provided on the top of the drainage frame 1. A filter groove 5 and a collection chamber 9 are respectively provided on both sides of the drainage frame 1. A filter screen plate 6 is provided in the filter groove 5, and a through groove 10 communicating with the collection chamber 9 is provided in the filter groove 5. Two sets of filter screen plates 6 and through grooves 10 are provided. Both filter screen plates 6 are inclined, with the bottom of the inclined position of the filter screen plate 6 flush with the bottom of the inner wall of the through groove 10. The mesh size of the two filter screen plates 6 decreases from coarse to fine from top to bottom. The two filter screen plates 6 can achieve stable filtration of water, filtering out impurities and debris. The inclined shape guides the filtered impurities and debris into the collection chamber 9 through the through groove 10. When the water flows, it can flush away the filtered impurities and debris, making it easier to collect them into the collection chamber 9. The entire structure ensures that the filter screen plates 6... The filtration efficiency is high, preventing clogging and water accumulation due to excessive impurities and debris. It also facilitates the collection and cleaning of filtered impurities and debris. A collection mesh frame 11 is nested inside the collection chamber 9. A drainage trough 14 communicating with the filter tank 5 is provided at the bottom of the drainage frame 1. A guide trough 15 communicating with the drainage trough 14 is provided at the bottom of the inner wall of the collection chamber 9. The guide trough 15 guides the water entering the collection chamber 9 into the drainage trough 14 to complete the drainage work. The top frame 2 is provided with mounting recesses 16 at positions corresponding to the filter tank 5 and the collection chamber 9. A cover plate 17 is nested in each of the two mounting recesses 16. One of the cover plates 17 is provided with an inlet 18 communicating with the filter tank 5. A fastening mechanism is provided between the two cover plates 17 and the two mounting recesses 16. The fastening mechanism can not only securely install the cover plate 17, but also easily disassemble and open it, making it convenient to remove the cover plate 17 and clean the internal structure.

[0030] The top of the drainage frame 1 is provided with a boss 3, and the bottom of the top frame 2 is provided with a groove 4. The boss 3 and the groove 4 are nested together. This structure allows the top frame 2 to be accurately and stably connected and installed with the drainage frame 1.

[0031] A mounting plate 7 is fixedly connected to the filter screen plate 6. The mounting plate 7 is tightened and fixed to the inner wall of the filter tank 5 by screws 8. There are multiple mounting plates 7 and screws 8, which can make the filter screen plate 6 stably rotate in the filter tank 5, and at the same time, it can be easily disassembled for cleaning or replacement of the filter screen plate 6.

[0032] A fixed rod 12 is fixedly connected to the top of the collection frame 11, and a pull handle 13 is fixedly connected to the fixed rod 12. By grasping the pull handle 13 and using the fixed rod 12, the collection frame 11 can be pulled out of the collection chamber 9, which facilitates the centralized cleaning of impurities and debris.

[0033] One of the cover plates 17 has a handle groove 26 on its top, which facilitates the disassembly of the cover plate 17.

[0034] The fastening mechanism includes a movable groove 19 on the cover plate 17 and a pin groove 22 on the inner wall of the mounting recess 16. A pin block 20 and a spring 21 are respectively provided in the movable groove 19. A connecting block 24 is fixedly connected to the top of the pin block 20. A toggle plate 23 is fixedly connected to the top of the connecting block 24 and above the cover plate 17. A guide groove 25 is provided on the top of the inner wall of the movable groove 19, which is nested and slidably engaged with the connecting block 24. The pin block 20 and the pin groove 22 are interlocked. During operation, the toggle plate 23 is slid, and the toggle plate 23 drives the pin block 20 to move through the connecting block 24. The pin block 20 retracts into the movable groove 19 and compresses the spring 21, thus locking the cover plate 17 into the mounting recess 16. After locking, the toggle plate 23 is released, and the spring 21 returns to its original position, pushing the pin block 20 into the pin groove 22, thus completing the fixed installation of the fastening mechanism. Similarly, it can also be easily disassembled.

[0035] Working principle: When using the easy-to-clean drainage structure, connect the drainage pipe to the inlet 18. During drainage, sewage enters the filter tank 5 from the inlet 18. When the water passes through the filter screen 6, impurities and debris in the water can be filtered out. The filtered water is discharged through the drainage trough 14. When the water flows, the impurities and debris on the filter screen 6 can be flushed and guided through the channel 10 into the collection chamber 9 and automatically fall into the collection frame 11. The water entering the collection chamber 9 is automatically discharged through the guide channel 15 into the drainage trough 14. When it is necessary to clean the collection frame 11, open the fastening mechanism, take out the cover plate 17, grasp the pull handle 13, and pull the collection frame 11 out of the collection chamber 9 through the fixing rod 12. This makes it easy to clean the impurities and debris in the collection frame 11. Similarly, the cover plate 17 on one side of the filter tank 5 can be opened to make it easy to remove the filter screen 6 for cleaning or replacement.
