Abstract
Description
Technical Field
[0001] The utility model mainly relates to the field of sponge cities, and particularly relates to a rainwater retention and infiltration system for sponge cities. Background Technique
[0002] A sponge city is a new generation of urban rain and flood management concept, which means that the city can be like a sponge and has good elasticity in adapting to environmental changes and coping with natural disasters brought by rainwater. It can also be called a "water elastic city".
[0003] The city can be like a sponge and has good "elasticity" in adapting to environmental changes and coping with natural disasters. The international general term is "low impact development rainwater system construction". When it rains, it absorbs, stores, infiltrates, and purifies water. When needed, the stored water is released and utilized to realize the free migration of rainwater in the city.
[0004] Starting from ecosystem services, the core of a sponge city is to build a water ecological infrastructure across scales and combine various specific technologies to build a water ecological infrastructure.
[0005] When the sponge city retains rainwater, the rainwater enters the interior of the infiltration system and then flows into the interior of the water tank for storage through the infiltration system.
[0006] The inventor found the following defects during the operation of specific embodiments:
[0007] However, the rainwater directly infiltrates into the interior of the water tank through the infiltration system, and the infiltration system cannot store the rainwater. When the rainfall is large and there is too much water in the water tank, the infiltration system cannot adjust the infiltration amount of the water entering the water tank, resulting in too much water flooding into the water tank at the same time.
[0008] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model

[0010] The utility model provides a rainwater retention and infiltration system for sponge cities to solve the technical problems existing in the above background technique.
[0011] 2. Technical solution:
[0012] To achieve the above object, the technical solution provided by the utility model is: a rainwater retention and infiltration system for sponge cities, including an infiltration housing, a support bar is arranged inside the infiltration housing, and an infiltration adjustment structure is arranged on the top of the support bar;
[0013] The infiltration adjustment structure includes a mounting plate. The bottom of the mounting plate fits against the top of the support bar. An installation groove is formed inside the mounting plate, and a first infiltration groove is formed inside the mounting plate. A sliding plate is slidably connected inside the installation groove, and an electric telescopic rod is provided between the installation groove and the sliding plate. A second infiltration groove is formed inside the sliding plate.
[0014] Furthermore, at the bottom of the inner wall of the infiltration housing, there are two guide plates which are inclined.
[0015] Furthermore, a first infiltration layer is provided inside the infiltration housing. The bottom of the first infiltration layer fits against the top of the infiltration adjustment structure, and a second infiltration layer is provided on the top of the first infiltration layer.
[0016] Furthermore, connecting pipes are provided on the outer walls on both sides of the infiltration housing. The connecting pipes are connected to the lowest points of the guide plates, and a filtering structure is provided at one end of each connecting pipe.
[0017] Furthermore, the filtering structure includes a filtering housing provided at one end of the connecting pipe. A water outlet is formed at the bottom of the filtering housing, and a filtering baffle is provided inside the filtering housing directly above the water outlet.
[0018] Furthermore, a humidity monitor is provided on the top of the infiltration housing, and one end of the humidity monitor is provided inside the second infiltration layer.
[0019] 3. Beneficial effects:
[0020] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:
[0021] With the adjustable infiltration adjustment structure of the present utility model, the infiltration speed of rainwater entering the infiltration housing can be adjusted to prevent rainwater from simultaneously entering the water tank through the infiltration system. At the same time, the first infiltration layer and the second infiltration layer inside the infiltration housing can filter impurities in the rainwater.
[0022] Plants can be planted on the top of the second infiltration layer. The plants can effectively absorb rainwater, increasing the absorption amount of rainwater by infiltration absorption. At the same time, when the second infiltration layer is relatively dry, the water in the water tank can be pumped back into the infiltration housing, and then the external high temperature heats the water in the infiltration housing, causing the water to evaporate and re-enter the first infiltration layer and the second infiltration layer to ensure the growth of the plants planted inside the infiltration housing.

[0032] Referring to the attached Figures 1-3 , a sponge city rainwater retention and infiltration system, comprising an infiltration housing 1, a support bar 3 is arranged inside the infiltration housing 1, and an infiltration adjustment structure 4 is arranged on the top of the support bar 3;
[0033] The infiltration adjustment structure 4 includes a mounting plate 401, the bottom of the mounting plate 401 is attached to the top of the support bar 3, an installation groove 402 is formed inside the mounting plate 401, a first infiltration groove 403 is formed inside the mounting plate 401, a sliding plate 404 is slidably connected inside the installation groove 402, an electric telescopic rod is arranged between the installation groove 402 and the sliding plate 404, and a second infiltration groove 405 is formed inside the sliding plate 404.
[0034] Furthermore, guide plates 2 are arranged at the bottom of the inner wall of the infiltration housing 1, the number of the guide plates 2 is two, the guide plates 2 are inclined. The water entering the inside of the infiltration housing 1 through the infiltration system enters the inside of the connecting pipe 7 along the inclined guide plates 2, and then the water enters the inside of the water tank through the connecting pipe 7 and the filtering structure for storage. The infiltration housing 1 can be installed in parks, rooftops, etc., and plants are planted inside the infiltration housing 1, which can effectively improve the greening of the sponge city.
[0035] Furthermore, a first infiltration layer 5 is arranged inside the infiltration housing 1, the bottom of the first infiltration layer 5 is attached to the top of the infiltration adjustment structure 4, a second infiltration layer 6 is arranged on the top of the first infiltration layer 5. The first infiltration layer 5 is composed of gravel, and the second infiltration layer 6 is composed of soil. Plant seeds are planted inside the second infiltration layer 6 to facilitate the germination of the seeds.
[0036] Furthermore, connecting pipes 7 are arranged on the outer walls on both sides of the infiltration housing 1, the connecting pipes 7 are connected to the lowest points of the guide plates 2, and a filtering structure is arranged at one end of the connecting pipes 7.
[0037] Furthermore, the filtering structure includes a filtering housing 8. The filtering housing 8 is disposed at one end of the connecting pipe 7. A water outlet 10 is formed at the bottom of the filtering housing 8. A filtering baffle 9 is disposed inside the filtering housing 8. The filtering baffle 9 is disposed directly above the water outlet 10. A humidity monitor 11 is disposed at the top of the permeation housing 1. One end of the humidity monitor 11 is disposed inside the second permeation layer 6. Rainwater enters the inside of the permeation housing 1 and enters the filtering structure through the connecting pipe 7 for filtering. At the same time, a water pump disposed in the water tank can also pump the water back into the inside of the permeation housing 1. After the rainwater in the permeation housing 1 evaporates, the water vapor moves upward and re-enters the inside of the first permeation layer 5 and the second permeation layer 6, facilitating the growth of plants planted inside the second permeation layer 6 subsequently.
[0038] In this embodiment, when it is necessary to collect rainwater in the sponge city through the permeation system, according to the amount of rainwater and the amount of water that can be accommodated in the water tank, the contact surface between the first permeation tank 403 and the second permeation tank 405 is adjusted. The electric telescopic rod is started, and the electric telescopic rod pushes the sliding plate 404 to slide on the inner wall of the installation groove 402, so that the contact surface between the first permeation tank 403 and the second permeation tank 405 can be adjusted, thereby adjusting the rainwater permeation speed.
[0039] Rainwater permeates through the second permeation layer 6 and the first permeation layer 5 and enters the inside of the permeation housing 1 through the gap between the second permeation tank 405 and the first permeation tank 403. Then the rainwater enters the filtering structure through the connecting pipe 7. The filtering baffle 9 in the filtering structure filters the rainwater, enabling the rainwater to enter the water tank. When the humidity monitor 11 monitors that the water content inside the second permeation layer 6 is relatively low, the water pump in the water tank pumps the water into the inside of the permeation housing 1, and then after the rainwater evaporates, it enters the inside of the first permeation layer 5 and the second permeation layer 6.
[0040] The above embodiments only represent a certain implementation manner of the present invention. The description is relatively specific and detailed, but it cannot be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
