Description

Technical Field

[0001] This utility model belongs to the field of urban drainage construction technology, and specifically relates to a sunken green space rainwater regulation and rapid infiltration structure. Background Technology

[0002] Sunken green space construction is an important infrastructure for rainwater regulation. It can collect rainwater that cannot infiltrate in time, reduce surface runoff, and avoid the drawbacks of urban waterlogging. Urban green belts not only play a role in greening the environment, but also play a role in storing groundwater during the dry season and rapidly infiltrating water into the ground during the rainy season. As we all know, this water regulation function is an important role of greening and planting trees.

[0003] There is currently no very effective way to deal with water accumulation in sunken green spaces. In most cases, the solution is to construct water pipes and pre-buried pipes to transfer and divert rainwater.

[0004] A search revealed a construction method for sunken green spaces based on sponge city principles, published under publication number CN 114753470 A. This method involves rainwater infiltration into the soil layer and collection via drainage pipes and inlet pipes. The entire process requires rainwater to infiltrate the soil layer, which is slow. In seasons or weather with heavy rainfall, the slow infiltration process can cause urban flooding. Therefore, the above technical solution has a low effectiveness in drainage and diversion.

[0005] Furthermore, in a rapid soil infiltration device for urban green spaces published in CN 119177705A, rainwater is collected and filtered through a filter disc; then, the rainwater is diverted to the first and second branch pipes through the main water pipe. However, in urban areas, fallen leaves and other debris can easily clog the filter disc during drainage.

[0006] To address the aforementioned issues, the applicant provides a technical solution for rapid rainwater infiltration and diversion. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a sunken green space rainwater regulation and rapid infiltration structure that can filter rainwater and remove some of the filtered debris, thus preventing the filter cylinder from being blocked prematurely.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A sunken green space rainwater regulation and rapid infiltration structure includes a water collection tank, a filter cylinder, a partition plate, and a water collection pipe. The water collection tank is located within the soil of the green area. The partition plate, water collection pipe, and filter cylinder are located within the water collection tank. The water collection pipe passes through the bottom of the water collection tank, and a diversion chamber is located at the bottom of the water collection pipe. The diversion chamber is buried deep underground, and a connecting pipe is provided on the diversion chamber, which connects to an external municipal flood diversion and overflow system. The filter cylinder is rotatably connected to the water collection pipe, and the partition plate is rotatably connected to the filter cylinder. An installation groove is provided on the inner wall of the water collection tank. The bottom of the pool is provided with a first through hole; the isolation plate is provided with an installation arm, which is inserted into the installation groove; the isolation plate is also provided with a scraper and a second through hole, and the scraper touches the filter cylinder; a first limiting plate and a second limiting plate are fixed on the water collection pipe; the bottom wall of the filter cylinder is located between the first limiting plate and the second limiting plate; several inclined plates are provided on the inner wall of the filter cylinder, a float plate is provided on the bottom wall of the filter cylinder, and a second filtration part is provided on the filter cylinder. The second filtration part is located above the inclined plates and forms a height difference, so that the water flow can generate an impact force.

[0010] The second limiting plate has a flange plate on one side, and the second limiting plate, which is fitted onto the filter cylinder, is fixed to the filter cylinder by bolts and the flange plate.

[0011] The filter cylinder is equipped with a sealing section, which is located above the second filter section. When the water flow is large, the buoyancy of the water can lift the debris to the sealing section, reducing the disadvantage of the debris directly clogging the second filter section. The filter cylinder is equipped with a conical cover to facilitate the insertion between the isolation plate and the filter cylinder.

[0012] The green belt surrounding the water collection pool is also equipped with a ventilation mechanism, including a connecting pipe, a gas distribution chamber, and a ventilation pipe. The connecting pipe is inserted into the ground from the ground, and the end of the connecting pipe is connected to the gas distribution chamber, which is connected to the ventilation pipe. The ventilation pipe is equipped with ventilation holes to provide oxygen to the roots of the green plants.

[0013] Furthermore, the second limiting plate is provided with a ball bearing and an annular pressure plate. The annular pressure plate and the second limiting plate are provided with ball bearing mounting holes. After the ball bearing is placed in the mounting hole on the second limiting plate, the annular pressure plate is fixed on the second limiting plate with bolts to make the ball bearing mounting hole complete and the ball bearing installation is completed.

[0014] Furthermore, a first filter section is installed at the port of the water collection tank, and the first filter section is raised above the ground; it can prevent fallen leaves and debris from entering the water collection tank with the water flow.

[0015] Furthermore, a cover plate fixed to the top of the water collection tank with bolts is installed to prevent fallen leaves and debris from being carried directly into the water collection tank when the water flow is large.

[0016] Furthermore, the diameter of the second through hole is larger than the diameter of the first through hole.

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] This solution enables rapid rainwater collection. The filter cartridge provides initial filtration of rainwater entering the collection pipe, preventing debris from clogging and hindering drainage. Furthermore, the different heights of the second filter section and the inclined plate create a downward impact force on the rainwater entering the filter cartridge. This impact causes the filter cartridge to rotate, which in turn causes a scraper to remove debris from the outer wall of the filter cartridge, preventing premature clogging and improving actual rainwater drainage. A stronger water flow results in better filter cartridge rotation, while a weaker flow carries less debris such as fallen leaves and weeds, reducing the likelihood of blockage. Finally, the use of ball bearings reduces friction between the filter cartridge and the collection pipe, further enhancing rotation efficiency.

[0019] In addition, an air exchange mechanism is installed in the soil of the planting layer to provide oxygen to the roots of the plants and promote their growth. Attached Figure Description

[0035] To facilitate understanding by those skilled in the art, the following is a detailed explanation in conjunction with the appendix. Figure 1-10 The technical solution of this utility model will be further described in detail below.

[0036] A sunken green space rainwater regulation and rapid infiltration structure includes a water collection tank 1, a filter cylinder 2, a partition plate 3, and a water collection pipe 4. The water collection tank 1 is located within the soil of the green area. The partition plate 3, water collection pipe 4, and filter cylinder 2 are located within the water collection tank 1. The water collection pipe 4 passes through the bottom of the water collection tank 1, and a diversion chamber 45 is provided at the bottom end of the water collection pipe 4. The diversion chamber 45 is buried deep underground, and a connecting pipe 46 is provided on the diversion chamber 45, which connects to an external municipal flood diversion and overflow equipment project. The filter cylinder 2 is rotatably connected to the water collection pipe 4, and the partition plate 3 is rotatably connected to the filter cylinder 2. An installation groove 11 is provided on the inner wall of the water collection tank 1, and a first through hole 1 is provided at the bottom of the water collection tank 1. 2; The isolation plate 3 is provided with an installation arm 32, which is inserted into the installation groove 11. The isolation plate 3 is also provided with a scraper 31 and a second through hole 33. The scraper 31 touches the filter cylinder 2. The water collection pipe 4 is fixedly provided with a first limiting plate 42 and a second limiting plate 43. The bottom wall of the filter cylinder 2 is located between the first limiting plate 42 and the second limiting plate 43. The inner wall of the filter cylinder 2 is provided with several inclined plates 23. The bottom wall of the filter cylinder 2 is provided with a float plate 21. The filter cylinder 2 is provided with a second filtration section 202. The second filtration section 202 is located above the inclined plates 23 and forms a height difference, so that the water flow can generate an impact force. The float plate is made of lightweight plastic plate.

[0037] The second limiting plate 43 has a flange plate 432 on one side. The second limiting plate 43, which is connected to the filter cylinder 2, is fixed on the filter cylinder 2 by bolts and flange plate 432.

[0038] The filter cylinder 2 is provided with a sealing part 201, which is located above the second filter part 202. When the water flow is large, the buoyancy of the water can lift the debris to the sealing part 201, reducing the disadvantage of the debris directly clogging the second filter part 202. The filter cylinder 2 is provided with a conical cover 24 to facilitate the insertion between the isolation plate 3 and the filter cylinder 2.

[0039] The green belt surrounding the water collection pool 1 is also equipped with a ventilation mechanism 5, including a through pipe 51, a gas distribution chamber 52, and a ventilation pipe 53. The through pipe 51 is inserted into the ground from the ground, and the end of the through pipe 51 is connected to the gas distribution chamber 52. The gas distribution chamber 52 is connected to the ventilation pipe 53. The ventilation pipe 53 is provided with ventilation holes, which can provide oxygen to the roots of the green plants.

[0040] Furthermore, the second limiting plate 43 is provided with a ball bearing 431 and an annular pressure plate 44. The annular pressure plate 44 and the second limiting plate 43 are provided with mounting holes for the ball bearing 431. After the ball bearing 431 is placed in the mounting hole on the second limiting plate 43, the annular pressure plate 44 is fixed on the second limiting plate 43 with bolts to make the mounting hole for the ball bearing 431 complete and to complete the installation of the ball bearing 431.

[0041] Furthermore, a first filter section 13 is provided at the port of the water collection tank 1, and the first filter section 13 is higher than the ground; it can prevent fallen leaves and debris from entering the water collection tank 1 with the water flow.

[0042] Furthermore, a cover plate 14 fixed to the top of the water collection tank 1 by bolts is provided to prevent fallen leaves and debris from being carried directly into the water collection tank 1 when the water flow is large.

[0043] Furthermore, the diameter of the second through hole 33 is larger than that of the first through hole 12. The larger diameter of the second through hole allows water to be stored at the bottom of the water collection pool, causing the floating plate to float. In addition, rainwater at the bottom of the water collection pool will gradually seep into the soil through the first through hole.

[0044] A sunken green space rainwater regulation and rapid infiltration structure, the working process of which is as follows:

[0045] Because sunken green spaces have the ability to collect water, they can quickly collect rainwater to the sunken ground when there is heavy rainfall, which can cause flooding. At this time, the collected rainwater will enter the collection pool 1. The rainwater enters the bottom of the collection pool 1 through the second through hole 33 and the first through hole 12. Then, under the buoyancy of the float plate 21, the filter cylinder 2 will be raised and touch the ball bearing 431. Then, the rainwater accumulated above the isolation plate 3 will enter the filter cylinder 2 through the second filter section 202. The height difference between the second filter section 202 and the inclined plate 23 will cause water flow to impact the inclined plate, thereby driving the filter cylinder 2 to rotate along the outer wall of the water collection pipe 4. This will cause the scraper 31 to scrape the outer wall of the filter cylinder 2, scraping away the fallen leaves, weeds and other debris that have entered the collection pool 1 from the filter cylinder 2, thus avoiding the disadvantage of being blocked in a short time.

[0046] The use of ball bearings 431 can reduce the friction of the filter cylinder 2 and improve the rotation effect; furthermore, the use of the first filter section 13 and the cover plate 14 further prevents the possibility of fallen leaves, weeds and other debris from entering the water collection pipe 4.

[0047] The rainwater collected by the water collection pipe 4 will be quickly transmitted through the pipe 46 to other external flood diversion and overflow engineering equipment for rapid flood diversion and diversion.

[0048] Furthermore, the ventilation system 5 can provide oxygen to the roots of the green plants in the green area 9, promoting their growth.

[0049] At the same time, the isolation plate 3 can be lifted out of the filter cylinder 2 along the mounting arm 32 to clean the debris inside.
