Description

Technical Field

[0001] This application relates to the field of rainwater filtration device technology, and more particularly to a rainwater purification device suitable for sponge cities. Background Technology

[0002] Sponge city is a new concept of urban stormwater management. Its main purpose is to enable cities to act like sponges, absorbing and storing rainwater during the rainy season, and then releasing and utilizing these water resources when needed, thereby achieving effective rainwater recycling and utilization, which can effectively mitigate the impact of natural floods caused by rainwater in cities. When cities use drainage pipes to absorb and store rainwater, the rainwater carries a large amount of fallen leaves and other garbage into the pipes. As the water flows, the garbage accumulates and can easily cause blockages in the drainage pipes. Furthermore, the long-term accumulation of fallen leaves and other garbage can cause corrosion and pollute the stored water resources, which can greatly affect the effective use of rainwater. It may even breed a large number of bacteria or viruses, which can have an adverse impact on the city's sanitation.

[0003] Therefore, there is an urgent need for a rainwater filtration device to address the shortcomings of existing sponge cities in absorbing and storing rainwater. Summary of the Invention

[0004] This application proposes a rainwater purification device suitable for sponge cities. It has the advantage of effectively filtering rainwater and preventing fallen leaves or other garbage carried in it from entering the water storage tank. This addresses the problem that when cities use drainage pipes to absorb and store rainwater, rainwater carries a large amount of fallen leaves and other garbage into the system. These garbage accumulates with the water flow, easily causing blockages in the drainage pipes. Furthermore, the long-term accumulation of fallen leaves or other garbage can cause corrosion, polluting the stored water resources and greatly affecting the effective use of rainwater. It may even breed a large number of bacteria or viruses, adversely affecting the city's sanitation.

[0005] To achieve the above objectives, this application adopts the following technical solution: a rainwater purification device suitable for sponge cities, comprising a cylindrical component with its top flush with the ground and its bottom connected to a manhole. A filter assembly is provided at the top of the inner cavity of the cylindrical component, and the top of the filter assembly is fixedly connected to a manhole cover installed at the top of the cylindrical component via a linkage component. Simultaneously, a water inlet is provided at the top left side of the outer surface of the cylindrical component, and the other end of the water inlet is connected to a drainage pipe, thereby allowing collected rainwater to enter a storage tank through the cylindrical component and the manhole for storage. The filter assembly includes a filter basket with a filter mesh at the bottom, which is movably fitted into the middle of the inner cavity of the cylindrical component. This allows rainwater, fallen leaves, and other debris entering the cylindrical component through the water inlet to be filtered out. A connecting rod is fixedly installed at the top of the filter basket, and the filter basket is elastically connected to the top of the inner cavity of the cylindrical component through the connecting rod. A second connecting groove is opened in the middle of one side of the outer surface of the filter basket for discharging the fallen leaves and other debris filtered out. A first connecting groove is opened in the middle of one side of the outer surface of the cylindrical component, located below the filter basket.

[0006] Furthermore, a sleeve is fixedly installed at the top of the inner cavity of the straight cylindrical component, and the top end of the connecting rod extends into the inner cavity of the sleeve. It forms a transmission connection with the sleeve through an elastic element that is movably sleeved on the top of the outer surface of the connecting rod, thereby forming an elastic connection between the filter basket and the straight cylindrical component, and forcing the filter basket to always remain in the state of returning to its initial position.

[0007] Furthermore, the linkage component includes a connecting shaft that is movably sleeved between the top of the outer surface and the inside of the manhole cover. The inner wall of the connecting shaft is threadedly connected to the top of the outer surface of the sleeve. The top of the connecting shaft is provided with an internal hexagonal slot. When the manhole cover needs to be opened, the connecting shaft can be rotated to separate it from the magnetic component. A magnetic component is fixedly installed on the top of the inner cavity of the connecting shaft, and a magnetic block with opposite magnetic poles to the magnetic component is fixedly installed on the top of the connecting rod. The setting of the magnetic component and the magnetic block on the top of the connecting rod can utilize the suddenness of magnetic connection and disconnection to ensure that the filter basket can only move downward after increasing its weight to a certain extent. This avoids the problem that the elastic component changes little by little. After the weight of the filter basket increases a little, it moves downward a little, which prevents the first and second connecting grooves from colliding and thus prevents the pouring action from being formed. This also prevents the problem that the fallen leaves and other garbage filtered on the filter basket cannot be completely discharged.

[0008] Furthermore, a baffle is fixedly installed on one side of the top of the filter basket and at a position corresponding to the second connecting groove. Thus, when the filter basket is in the initial position, the baffle can be used to block the first connecting groove on the straight cylinder to effectively prevent water from flowing out through the first connecting groove.

[0009] Furthermore, a set of connecting pipes is provided on the left side of the inner cavity of the water inlet pipe, which is connected to the drainage pipe. The connecting pipes are eccentrically connected to the water inlet pipe, thereby forming a groove for depositing silt at the bottom of the inner cavity of the water inlet pipe.

[0010] Furthermore, a drain pipe is fixedly installed on the top left side of the inner wall of the cylindrical component, and the top end of the drain pipe is connected to the inner cavity of the water inlet. A limiting rod is fixedly installed on the top left side of the inner wall of the filter basket. The top end of the limiting rod extends into the interior of the drain pipe and initially blocks the drain pipe. When the limiting rod moves downward with the filter basket to the lower position, the drain pipe is also connected to discharge the sludge deposited at the bottom of the inner cavity of the water inlet.

[0011] Furthermore, a first tank connected to the first connecting groove is provided at the bottom right side of the outer surface of the cylindrical component, and a second tank connected to the bottom end of the sewage pipe is provided at the top left side of the outer surface of the cylindrical component. Thus, under the action of the first tank and the second tank, fallen leaves, other garbage and silt can be collected and cleaned in a centralized manner. The top of the outer surface of the first tank and the second tank are provided with through holes. At the same time, the through holes allow the water vapor contained in the fallen leaves, other garbage and silt to evaporate and be absorbed by the soil.

[0012] The beneficial effects of this invention are as follows: This application provides a rainwater purification device suitable for sponge cities. Regarding the filter assembly, as the amount of fallen leaves and other debris filtered by the filter basket gradually increases, the flow of rainwater at its bottom gradually decreases. This causes rainwater to continuously accumulate in the filter basket, increasing its weight until the weight of the filter basket overcomes the magnetic force of the magnetic components and blocks, causing it to move downwards. When the second connecting groove coincides with the first connecting groove, a large amount of rainwater accumulated in the filter basket is discharged outwards through the first and second connecting grooves, carrying the fallen leaves and other debris filtered by the filter basket out of the inner cavity of the straight cylinder. This effectively filters rainwater and prevents the fallen leaves or other debris carried by the rainwater from entering the water storage tank. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] like Figure 1 , Figure 2 As shown, a rainwater purification device suitable for sponge cities includes a cylindrical component 1 with its top flush with the ground and its bottom connected to a manhole. A filter assembly 5 is located at the top of the inner cavity of the cylindrical component 1, and the top of the filter assembly 5 is fixedly connected to a manhole cover 6 located at the top of the cylindrical component 1 via a linkage component 7. Simultaneously, a water inlet 8 is located on the top left side of the outer surface of the cylindrical component 1 and is connected thereto. The other end of the water inlet 8 is connected to a drainage pipe, allowing collected rainwater to pass through the cylindrical component 1 and the manhole into a storage tank for storage. Figure 4 , Figure 5 As shown, the filter assembly 5 includes a filter basket 12 with a filter mesh at the bottom, which is movably sleeved in the middle of the inner cavity of the cylindrical component 1. This allows rainwater, fallen leaves, and other garbage entering the cylindrical component 1 through the water inlet 8 to be filtered out. A connecting rod 13 is fixedly installed at the top of the filter basket 12, and the filter basket 12 is elastically connected to the top of the inner cavity of the cylindrical component 1 through the connecting rod 13. A second connecting groove 14 for discharging the fallen leaves and other garbage filtered out is opened in the middle of one side of the outer surface of the filter basket 12. A first connecting groove 9 located below the filter basket 12 is opened in the middle of one side of the outer surface of the cylindrical component 1. As the amount of fallen leaves and other garbage filtered by the filter basket 12 gradually increases, the flow of rainwater at its bottom gradually decreases, causing rainwater to continuously accumulate in the filter basket 12 and its weight to continuously increase until the weight of the filter basket 12 overcomes the elastic force of the linkage component 7 and moves downward. When the second connecting groove 14 and the first connecting groove 9 overlap, a large amount of rainwater accumulated in the filter basket 12 is poured out through the first connecting groove 9 and the second connecting groove 14, carrying the fallen leaves and other garbage filtered by the filter basket 12 out of the inner cavity of the straight cylinder 1. Once the rainwater collected in the filter basket 12 has finished pouring out, its mass becomes lighter and it automatically returns to its initial position under the elastic force of the linkage component 7, continuing to filter the rainwater.

[0017] like Figure 4 , Figure 6 As shown, in this technical solution, a sleeve 10 is fixedly installed on the top of the inner cavity of the straight cylinder 1, and the top end of the connecting rod 13 extends into the inner cavity of the sleeve 10. The elastic member 19, which is movably sleeved on the top of the outer surface of the connecting rod 13, forms a transmission connection with the sleeve 10, thereby forming an elastic connection between the filter basket 12 and the straight cylinder 1, and forcing the filter basket 12 to always remain in the state of returning to the initial position.

[0018] like Figure 6 As shown, in this technical solution, the linkage component 7 includes a connecting shaft 17 that is movably connected to the top of the outer surface of the manhole cover 6. The inner wall of the connecting shaft 17 is threadedly connected to the top of the outer surface of the sleeve 10. The top of the connecting shaft 17 is provided with an internal hexagonal slot. When the manhole cover 6 needs to be opened, the connecting shaft 17 can be rotated to separate it from the magnetic component 18. The magnetic component 18 is fixedly installed on the top of the inner cavity of the connecting shaft 17, and a magnetic block with opposite magnetic poles to the magnetic component 18 is fixedly installed on the top of the connecting rod 13. The setting of the magnetic component 18 and the magnetic block on the top of the connecting rod 13 can utilize the suddenness of magnetic connection and disconnection to make the filter basket 12 move downward only after it increases to a certain weight. This avoids the problem that the elastic component 19 changes little by little. After the weight of the filter basket 12 increases a little, it moves downward a little, so that the first connecting groove 9 and the second connecting groove 14 overlap and cannot form a pouring action, resulting in the problem that the fallen leaves and other garbage filtered on the filter basket 12 cannot be completely discharged.

[0019] like Figure 5 As shown, in this technical solution, a baffle 15 is fixedly installed on one side of the top of the filter basket 12 and at a position corresponding to the second connecting groove 14. Thus, when the filter basket 12 is in the initial position, the baffle 15 can be used to block the first connecting groove 9 on the straight cylinder 1 to effectively prevent water from flowing out through the first connecting groove 9.

[0020] like Figure 1 , Figure 3 As shown, in this technical solution, a set of connecting pipes is provided on the left side of the inner cavity of the water inlet 8 to connect with the drainage pipe. The connecting pipes are eccentrically connected to the water inlet 8, thereby forming a groove for sediment deposition at the bottom of the inner cavity of the water inlet 8.

[0021] like Figure 1 , Figure 4 as well as Figure 5 As shown, in this technical solution, a drain pipe 11 is fixedly installed on the top left side of the inner wall of the cylindrical component 1. The top end of the drain pipe 11 is connected to the inner cavity of the water inlet 8. A limiting rod 16 is fixedly installed on the top left side of the inner wall of the filter basket 12. The top end of the limiting rod 16 extends into the interior of the drain pipe 11 and initially blocks the drain pipe 11. When the limiting rod 16 moves downward with the filter basket 12 to the lower position, the drain pipe 11 is also connected to discharge the sludge deposited at the bottom of the inner cavity of the water inlet 8.

[0022] like Figure 1 As shown, in this technical solution, the bottom right side of the outer surface of the cylindrical component 1 is provided with a first tank 2 that communicates with the first connecting groove 9, while the top left side of the outer surface of the cylindrical component 1 is provided with a second tank 3 that communicates with the bottom end of the sewage pipe 11. Thus, under the action of the first tank 2 and the second tank 3, fallen leaves, other garbage and silt can be collected and cleaned in a centralized manner. The top of the outer surface of the first tank 2 and the second tank 3 are both provided with through holes 4. At the same time, the setting of the through holes 4 allows the water vapor contained in the fallen leaves, other garbage and silt to evaporate and be absorbed by the soil.

[0023] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
