Description

Technical Field

[0001] The present invention belongs to the technical field of sponge city seepage and drainage structures, and specifically relates to a sponge city seepage and drainage structure and a sponge city water circulation system. Background Art

[0002] The water system circulation structure of sponge city mainly consists of infiltration and drainage structure, net retention structure and water use structure. Sponge city is an emerging urban construction method that aims to alleviate urban water pressure, reduce water pollution risks and avoid urban floods through a series of measures. This new urban water circulation structure not only helps protect the environment, but also achieves sustainable use of water resources.

[0003] The infiltration and drainage structure of the sponge city is an important part of the urban water circulation system. It is composed of elements such as the permeable surface layer, the drainage permeable layer and the reservoir. The design of this structure aims to imitate the natural water cycle process. The permeable surface layer allows rainwater to penetrate into the soil. At the same time, the drainage permeable layer and the perforated blind pipe system ensure that excess water can be quickly discharged to prevent urban waterlogging. The reservoir serves as a rainwater storage facility. It can release the stored water resources during droughts or extreme weather conditions, realize the effective collection, purification and reuse of rainwater, thereby improving the efficiency of urban water resource utilization, reducing the pressure on the urban drainage system, and promoting the improvement of the urban ecological environment.

[0004] The net retention structure is mainly responsible for collecting and temporarily storing rainwater for subsequent use or discharge. In sponge cities, the net retention structure is usually composed of rain gardens, storage tanks and other facilities. These facilities can effectively slow down the flow rate of rainwater and increase the contact time between rainwater and soil, thereby promoting the natural purification process of rainwater.

[0005] The water use structure mainly involves using the collected rainwater for urban greening, road washing, industrial water use, etc. This structure ensures the reuse of rainwater resources and reduces dependence on traditional water resources.

[0006] Implementing the renovation of the seepage and drainage structure of sponge cities in already built communities faces many practical disadvantages. First of all, it is almost impossible to completely dismantle and reinstall the entire structure, because such a huge amount of work requires not only the demolition of existing buildings and infrastructure, but also a thorough renovation of underground pipes and drainage systems. Reinstalling the seepage and drainage structure means a lot of demolition and reconstruction work, which involves complex construction organization and coordination, as well as possible long-term inconvenience to residents' lives. The cost of completely dismantling and reinstalling the seepage and drainage structure is extremely high, and the underground space of the existing community may not be able to meet the needs of the new seepage and drainage structure. In the later stage, there may be better solutions based on the innovation of materials and technology.

[0007] The transformation of the sponge city's infiltration and drainage structure requires more cautious and innovative solutions. It may be necessary to gradually improve the water circulation system through local optimization, gradual implementation, or modular, scalable design to reduce costs, shorten construction periods, and reduce the impact on residents' lives. These applications have a large demand and a very large market. At the same time, they can be better utilized in urban supporting facilities, providing a prerequisite for further improving the quality of life of owners with just-in-time needs. Summary of the invention

[0008] The purpose of the present invention is to provide a sponge city drainage structure and a sponge city water circulation system in order to solve the above-mentioned problems.

[0009] The technical solution adopted by the present invention is as follows: a sponge city infiltration and drainage structure and a sponge city water circulation system, including a water reservoir, a siphon inlet welded on the upper surface of the water reservoir, a siphon outlet fixedly connected to the upper surface of the water reservoir, side baffles fixedly connected to the outer surfaces on both sides of the siphon outlet, a guide frame fixedly connected to the outer surface above the siphon outlet corresponding to the side baffle, and a buoyancy plate movably connected to the inner surface of the guide frame.

[0010] By adopting the above technical solution, we need to set up the water reservoir in a location with low terrain or prone to flooding. After collecting the accumulated water in the trough, it will gradually submerge the siphon outlet and the side baffle, float up through the lightweight principle of the buoyancy plate, and guide the frame to assist the displacement of the buoyancy plate. After a channel is formed between the buoyancy plate and the siphon outlet, the water flows through the siphon inlet to the inside of the water reservoir through the siphon effect, thereby achieving the water storage effect. Through the storage of the water reservoir, the seepage and drainage structure of the equipment is convenient for early optimization in cities or communities without a full-scale "sponge city" structure. Under the condition of effectively alleviating flood disasters, it is convenient for gradual optimization in the later stage to gradually achieve the vision of a "sponge city".

[0011] In a preferred embodiment, a blocking plate is movably connected to the inner surface of the siphon inlet corresponding to the siphon outlet, a connecting rod is fixedly connected to the lower surface of the blocking plate, and a floating ball is fixedly connected to the lower surface of the connecting rod.

[0012] By adopting the above technical solution, the water level drives the connecting rod and the blocking plate to float up through the buoyancy of the float ball. When the water storage tank can no longer store water, the blocking plate presses against the corresponding opening of the siphon outlet.

[0013] In a preferred embodiment, a water level meter is fixedly connected to the inner surface of the water reservoir, and a circuit control body is fixedly connected to the outer surface of the water reservoir.

[0014] By adopting the above technical solution, the water level meter can conveniently measure the water level stored in the reservoir in real time, and the circuit control body can conveniently transmit the measured water level or extended measurement result analysis to the remote control console.

[0015] In a preferred embodiment, an upper cover plate is movably connected to the upper surface of the water reservoir, and a pull ring is fixedly connected to the upper surface of the upper cover plate.

[0016] By adopting the above technical solution, by applying external force to the pull ring, the upper cover plate can be easily pulled out to clean the inside of the water tank or check the water level meter.

[0017] In a preferred embodiment, an external pipe is welded to the outer surface of the water reservoir, and a sealing plug is provided on the outer surface of the external pipe.

[0018] By adopting the above technical solution, the external pipe can be easily connected to external equipment to form a water circulation system, and the sealing plug can be easily blocked to facilitate future expansion.

[0019] In a preferred embodiment, a one-way valve is fixedly connected to the outer surface of the external pipe, and a manual valve is provided on the outer surface of the external pipe.

[0020] By adopting the above technical solution, the manual valve facilitates the connection of the manual switch to the water reservoir, and the one-way valve facilitates the corresponding one-way entry and outflow of water from the water reservoir.

[0021] In a preferred embodiment, a collecting trough is fixedly connected to the outer surface of the siphon inlet, and a leakage plate is fixedly connected to the outer surface of the upper end of the collecting trough.

[0022] By adopting the above technical solution, the equipment absorbs water into the collection trough through the seepage board covered with sponge city material.

[0023] In a preferred embodiment, an electronic diversion body is fixedly connected to the outer surface of the one-way valve, a water pump is fixedly connected to the outer surface of the electronic diversion body, and a drainage shell is fixedly connected to the outer surface of the electronic diversion body.

[0024] By adopting the above technical solution, the circuit control body controls the electronic diversion body to adjust the outlet, and the water pump can be easily directed to the place where watering or fountain landscape is needed. The drainage shell can be directly directed to the water reservoir or water storage unit at the next location for rapid drainage.

[0025] In a preferred embodiment, the outer surface of the one-way valve is fixedly connected to a connecting water pipe, the outer surface of one end of the water pump away from the one-way valve is fixedly connected to a sedimentation tank, and the upper surface of the sedimentation tank is movably connected to a manhole cover.

[0026] By adopting the above technical solution, rainwater collected from the road is filtered through sedimentation tanks, and then flows into the reservoir through connecting water pipes for storage. The manhole cover is folded to clean impurities, while preventing impurities filtered in the sedimentation tank from being flipped out due to the impact of water flow, causing secondary pollution.

[0027] In a preferred embodiment, a rain gutter is provided on the upper surface of the manhole cover, and a rainwater cover is movably connected to the upper surface of the rain gutter.

[0028] By adopting the above technical solution, the rainwater cover guides the road rainwater into the rainwater gutter for collection by filtering impurities such as larger leaves.

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0030] In the present invention, we need to set the water reservoir in a location with low terrain or prone to flooding. After collecting the accumulated water in the leakage trough, it gradually submerges the siphon outlet and the side baffle, floats up through the lightweight principle of the buoyancy plate, and the guide frame assists the displacement of the buoyancy plate. After the buoyancy plate and the siphon outlet form a channel, the water flows through the siphon inlet to the inside of the water reservoir through the siphon effect, thereby achieving the water storage effect. Through the storage of the water reservoir, the seepage and drainage structure of the equipment is convenient for early optimization in cities or communities without all-round "sponge city" construction. Under the condition of effectively alleviating flood disasters, it is convenient for gradual optimization in the later stage to gradually achieve the vision of "sponge city".

[0042] We need to set the water reservoir 1 in a location with low terrain or prone to flooding. After collecting the accumulated water in the trough 18, it will gradually submerge the siphon outlet 3 and the side baffle 4, and float up through the lightweight principle of the buoyancy plate 6. The guide frame 5 assists the displacement of the buoyancy plate 6. After a channel is formed between the buoyancy plate 6 and the siphon outlet 3, the water flows through the siphon inlet 2 to the inside of the water reservoir 1 through the siphon effect, so as to achieve the water storage effect. Through the storage of the water reservoir 1, the seepage and drainage structure of the equipment is convenient for early optimization in cities or communities without all-round "sponge city" construction. Under the condition of effectively alleviating flood disasters, it is convenient for gradual optimization in the later stage to gradually achieve the vision of "sponge city".

[0048] By applying external force to the pull ring 13 , the upper cover plate 12 can be easily pulled out to clean the inside of the water tank 1 or to check the water level meter 10 .

[0049] Reference Figure 1-5 An external pipe 14 is welded to the outer surface of the water reservoir 1 , and a sealing plug 15 is provided on the outer surface of the external pipe 14 .

[0050] The external pipe 14 is convenient for connecting with external equipment to form a water circulation system, and the sealing plug 15 is convenient for sealing the external pipe 14 that is not currently needed to be connected, so as to facilitate later expansion.

[0051] Reference Figure 1-5 A one-way valve 16 is fixedly connected to the outer surface of the external pipe 14 , and a manual valve 17 is arranged on the outer surface of the external pipe 14 .

[0056] The circuit control body 11 controls the electronic diversion body 20 to adjust the outlet, and the water pump 21 conveniently guides the water to the place where watering or fountain landscape is needed, and the drainage shell 22 conveniently guides the water directly to the water reservoir 1 or water storage unit at the next location for rapid drainage.

[0058] After the road rainwater is collected and filtered in the sedimentation tank 24, the water flows into the water reservoir 1 through the connecting water pipe 23 for water storage. The manhole cover 25 cleans the impurities by folding, and at the same time prevents the impurities filtered in the sedimentation tank 24 from being flipped out due to the impact of water flow, causing secondary pollution.

[0059] Reference Figure 1-2 A rain gutter 26 is arranged on the upper surface of the manhole cover 25 , and a rainwater cover 27 is movably connected to the upper surface of the rain gutter 26 .

[0061] The implementation principle of the sponge city drainage structure and the sponge city water circulation system embodiment of the present invention is:

[0062] The equipment absorbs water into the collection trough 18 through the seepage plate 19 covered with sponge city material. Similarly, we need to set the water reservoir 1 in a low-lying or flood-prone location. After the water accumulates in the collection trough 18, it gradually submerges the siphon outlet 3 and the side baffle 4, and floats up through the lightweight principle of the buoyancy plate 6. The guide frame 5 assists the displacement of the buoyancy plate 6. After the buoyancy plate 6 and the siphon outlet 3 form a channel, the water flows through the siphon inlet 2 to the inside of the water reservoir 1 through the siphon effect, and achieves the water storage effect. The water level is measured by the water level meter 10 through the storage of the water reservoir 1. The water level is driven by the buoyancy of the float 9 to float the connecting rod 8 and the sealing plate 7. After the storage capacity of the water reservoir 1 can no longer store water, the sealing plate 7 is pressed against the corresponding port of the siphon outlet 3. After discharge Continue to absorb to achieve the "sponge" effect. The circuit control body 11 is convenient for transmitting the measured water level or extended measurement result analysis to the remote control console. The external pipe 14 is convenient for connecting with external equipment to form a water circulation system. The manual valve 17 is convenient for manual switching. The one-way valve 16 is convenient for water to enter and flow out of the reservoir 1 in one direction. The circuit control body 11 controls the electronic diversion body 20 to adjust the outlet. The water pump 21 is convenient for exporting to the place where watering or fountain landscape is needed. The drainage shell 22 is convenient for directly exporting to the reservoir 1 or water storage unit at the next location for rapid drainage. Similarly, the rainwater cover 27 and the rainwater gutter 26 collect rainwater from the road. After filtering impurities in the sedimentation tank 24, the water flows into the reservoir 1 through the connecting water pipe 23 for water storage.
