Description

Technical Field

[0001] This utility model relates to the field of municipal drainage technology, and more specifically, it relates to an adjustable drainage channel for municipal green belts. Background Technology

[0002] With the acceleration of urbanization, municipal green belts, as an important part of the urban ecological environment, have functions that are not limited to beautifying the environment, but also include regulating the urban microclimate, purifying the air, and mitigating rainwater runoff. However, during rainfall, green belts often face the problem of poor drainage, leading to waterlogging, affecting plant growth, and even causing soil erosion and damage to the green belt structure. Therefore, how to effectively solve the drainage problem of municipal green belts has become an important issue in the fields of urban planning and municipal engineering.

[0003] Most existing drainage facilities lack flexibility and cannot be dynamically adjusted according to the actual needs of green belts, resulting in unsatisfactory drainage effects. When the inlet opening of the drainage box is too large, the drainage box is more likely to be clogged by impurities on a daily basis. When the inlet opening of the drainage box is too small, it affects the drainage efficiency when the rainfall is heavy, and the impurities that enter the drainage box are difficult to classify and collect, which makes it difficult to clean the impurities.

The adjusting screw 13 and the adjusting block 14 rotate relative to each other, which drives the adjusting block 14 and the movable plate 3 to move. When the movable plate 3 moves, it adjusts the overlap of the first drain hole 4 and the second drain hole 5, thereby adjusting the water flow area.

[0031] Please see Figures 4-5 As one embodiment of the drainage trough for the drainage tank 1: the collection frame 10 includes a filter screen 19, a support partition 20 is provided on the filter screen 19, a filter partition 21 is provided on the support partition 20, a second filter hole 22 is provided on the filter partition 21, the radius of the second filter hole 22 is larger than the radius of the first filter hole 8, a drainage pump 23 is provided inside the drainage tank 1, a drainage pipe 24 is connected to the drainage pump 23, an installation sleeve 25 is provided on the drainage pipe 24, and a filter screen 26 is provided on the installation sleeve 25.

[0032] More specifically, the collection frame 10 is installed through the support block 11 and the support frame 12. Rainwater flows into the filter plate 7 through the water guide plate 6. The first filter hole 8 on the filter plate 7 filters the rainwater, allowing only water to flow through the first filter hole 8. The remaining impurities enter the collection frame 10. Mud and other impurities fall onto the filter screen 19 on one side of the support partition 20 after being filtered by the second filter hole 22 on the filter partition 21. Large impurities such as leaves are filtered onto the filter screen 19 on the other side of the support partition 20. The water on the impurities flows into the drainage tank 1 through the filter screen 19. By setting the protrusion 9, it is prevented that leaves and other impurities stick to the filter plate 7 and block the filter plate 7. The drainage pump 23 is started, and after being filtered by the filter screen 26, the excess rainwater is discharged through the drainage pipe 24.

[0033] In summary, when the overall equipment is in use or running: when adjusting the water inlet area, rotate the adjusting handle 18. The adjusting handle 18 and the adjusting rod 15 drive the first bevel gear 16 and the second bevel gear 17 to cooperate, which drives the adjusting screw 13 to rotate. The adjusting screw 13 and the adjusting block 14 rotate relative to each other, which drives the adjusting block 14 and the movable plate 3 to move. When the movable plate 3 moves, it adjusts the overlap of the first drain hole 4 and the second drain hole 5, thereby adjusting the water flow area.

[0034] The collection frame 10 is installed through the support block 11 and the support frame 12. Rainwater flows into the filter plate 7 through the water guide plate 6. The first filter hole 8 on the filter plate 7 filters the rainwater, allowing only water to flow through the first filter hole 8. The remaining impurities enter the collection frame 10. Soil and other impurities fall onto the filter screen 19 on one side of the support partition 20 after being filtered by the second filter hole 22 on the filter partition 21. Large impurities such as leaves are filtered onto the filter screen 19 on the other side of the support partition 20. The water on the impurities flows into the drainage tank 1 through the filter screen 19. The protrusion 9 is set to prevent leaves and other impurities from sticking to the filter plate 7 and clogging it. The drainage pump 23 is started, and after being filtered by the filter screen 26, the excess rainwater is discharged through the drainage pipe 24.
