Description

Technical Field

[0001] The invention relates to the technical field of subway station engineering, and in particular to an ecological closed-mouth subway piston wind pavilion with rainwater collection and purification functions. Background Art

[0002] Wind booths are important ventilation facilities in subway stations. They are responsible for the ventilation of underground stations and tunnels. They include fresh air booths, exhaust booths and piston wind booths. Among them, piston wind booths are set up for air circulation in underground stations and tunnels. When the train is running in the tunnel, the tunnels at both ends of the station will suck and exhaust air. The airflow accumulates in front of the train, squeezing the air forward and pushing the air out through the piston wind booth in front of the train. At this time, a negative pressure difference is formed at the rear of the train, which can suck the ground air into the train tunnel. It is precisely because of the piston wind booth that the air in the tunnel can be discharged and replenished in time.

[0003] Since the piston wind pavilion is part of the ground building of the subway station, rainwater needs to be drained and treated after falling in. However, when treating rainwater in the piston wind pavilion, the rainwater is collected and discharged into the rainwater pipe network, and there is a lack of treatment for pollutants carried by rainwater washing the top of the wind shaft and the surrounding surface runoff, which brings a lot of burden to the terminal to reduce rainwater runoff pollution and is not conducive to the normal function of the piston wind pavilion.

[0004] Therefore, it is necessary to propose new measures to overcome the above-mentioned defects. Summary of the invention

[0031] The top of the traditional piston wind pavilion is above the ground and only has ventilation function. It is easy for rainwater to enter and affect the appearance of the ground environment. Figure 1 The present invention provides an ecological closed-end subway piston wind pavilion with rainwater collection and purification functions, aiming to achieve multiple functions such as sunshade (cooling) ventilation, power generation, and water resource purification and reuse. The present invention has carried out landscape transformation on the subway ground building, greening and decorating the piston wind pavilion located above the ground, and providing a watering system for green plants that does not require external energy, which not only beautifies the exposed part of the piston wind pavilion, but also does not require additional energy consumption.

[0032] Specifically, the present invention adopts a steel wind pavilion structure, and the side walls of the steel wind pavilion are provided with transverse ventilation slots to replace the original shutter structure. In addition, the present invention also includes a wind-driven power generation device 9, a vertical greening module 3, a bulk water storage tank 15 and a purified rainwater storage tank 16.

[0033] The vertical greening module 3 is arranged on the outer wall of the steel wind pavilion. The vertical greening module 3 includes a basin and plants, which are evenly arranged in the transverse ventilation slots to form a green enclosure structure of the outer wall of the steel wind pavilion. The vertical greening module 3 will not completely close the steel wind pavilion, and the steel wind pavilion can also achieve internal and external gas convection through the transverse ventilation slots. Among them, a short rain shielding plate 4 is arranged on the top of the transverse ventilation slot to prevent rainwater from entering the steel wind pavilion from the side through the transverse ventilation slot. An angle iron 5 is arranged on the outside of the bottom of the transverse ventilation slot to support and fix the basin.

[0034] The wind-driven power generation equipment 9 is arranged on the inner wall of the steel wind pavilion. The wind-driven power generation equipment 9 includes wind wheel blades, magnetic induction line generators and an electric control system. The wind force of the piston wind in the steel wind pavilion is used to generate electric energy, which can be stored to supply power to surrounding electrical equipment. The wind-driven power generation equipment 9 used in the present invention is an existing small-sized equipment, and the number of deployments can be determined according to actual needs.

[0035] The scattered water storage tank 15 and the purified rainwater storage tank 16 are arranged on one side outside the steel structure wind pavilion. A scattered water pumping pipe 7 is arranged between the scattered water storage tank 15 and the vertical greening module 3, and a pumping pump 12 is arranged on the pipe. The scattered water storage tank 15 is used to store rainwater collected from the scattered water outside the steel structure wind pavilion, and is transported to the vertical greening module 3 for watering plants with the help of the pumping pump 12. A purified water delivery pipe 8 is arranged between the vertical greening module 3 and the purified rainwater storage tank 16, which is used to transport rainwater purified by the vertical greening module 3 to the purified rainwater storage tank 16.

[0036] The wind-driven power generation device 9 is connected to the power storage device 10, and then connected to the water pump 12. Under the wind force of the piston wind in the steel wind pavilion, the output current of the magnetic induction line generator of the wind-driven power generation device 9 is transmitted to the power storage device 10 connected to the water pump 12 through the wire, and then connected to the rectifier through the wire to output a stable current to supply the water pump 12.

[0037] like Figure 1 The scattered water storage tank 15 and the purified rainwater storage tank 16 are both part of the rainwater purification tank. The interior of the rainwater purification tank is the initial abandoned flow area 14, the scattered water storage tank 15 and the purified rainwater storage tank 16 in sequence. The inner side of the top of the rainwater purification tank is the scattered water outside the steel structure wind pavilion, and the top of the initial abandoned flow area 14 is the rainwater collection grate 13. The initial abandoned flow area 14 and the scattered water storage tank 15 are separated by a first vertical plate, and an overflow hole is provided at the lower part of the first vertical plate. The rainwater collected by the scattered water outside the steel structure wind pavilion first enters the initial abandoned flow area 14 through the rainwater collection grate 13, settles and stands still, and enters the scattered water storage tank 15 through the overflow hole after the water level rises, and is used for plant watering. The scattered water pumping pipe 7 is connected to the plant dripping pipe 6 corresponding to each vertical greening module 3.

[0038] The bulk water storage tank 15 and the purified rainwater storage tank 16 are separated by a second vertical plate. The purified rainwater storage tank 16 is provided with a drain outlet, and the purified rainwater can be discharged and transported to the surrounding area for other uses.

[0039] In addition, the top of the steel structure wind pavilion is a roof water collection area 1, which can also collect rainwater. The roof water collection area 1 is provided with a rainwater purification diversion pipe 2, and the rainwater purification diversion pipe 2 is connected to the plant drip pipe 6 corresponding to each vertical greening module 3. This part of rainwater can also be purified by the vertical greening module 3.

[0040] After the above structure is in operation, the plants in the vertical greening module 3 can be watered in a variety of ways:

[0041] 1. Rainwater collected on the top of the steel structure wind pavilion is directly irrigated

[0042] After the rainwater is collected in the roof water collection area 1 through the diversion groove, it is introduced into the plant drip pipe 6 through the rainwater purification diversion pipe 2 to water the plants in the vertical greening module 3.

[0043] 2. The top of the rainwater purification tank is used to collect rainwater for irrigation

[0044] Rainwater is also collected at the top of the rainwater purification tank. The rainwater collected through the diversion groove enters the initial abandonment area 14 through the rainwater collection grate 13, and then overflows into the scattered water storage tank 15. The water pump 12 is used to introduce the rainwater in the scattered water storage tank 15 into the plant drip pipe 6 through the scattered water pumping pipe 7 to water the plants in the vertical greening module 3.

[0045] 3. Purified water irrigation

[0046] The purified rainwater storage tank 16 stores purified rainwater, which can be used for other purposes and can also be used as a supplement to the irrigation water source of the vertical greening module 3. A return pipe and a water pump are set at the drain outlet of the purified rainwater storage tank 16 to introduce the plant drip pipe 6.

[0047] like Figure 2 The principle of vertical greening to purify rainwater is to purify it through plants and purification fillers. The structure mainly includes purification plants 17, coconut bran mixed with ceramic nutrient soil 18, and crushed ceramsite mixed with medical stone 19. Among them, coconut bran mixed with ceramic nutrient soil 18 is a plant culture matrix, and crushed ceramsite mixed with medical stone 19 is a purification filler. Purification plants 17, such as green radish, can have a certain purification ability for TN, TP and COD in water. Then coconut bran mixed with ceramic nutrient soil 18 is used as a culture medium to reduce organic pollution. The purification filler mainly uses crushed ceramsite mixed with medical stone 19, which can effectively purify TN, TP and COD.

[0048] In the present invention, the water pump 12 of the electric equipment does not need an external energy source, and is equipped with a water pump generator 11. The piston wind in the steel structure wind pavilion blows the wind wheel blades of the wind-driven power generation equipment 9, thereby generating electricity and storing it in the power storage device 10, which is then supplied to the water pump generator 11 and starts the water pump 12.

[0049] The present invention uses piston wind power generation through wind-driven power generation equipment to achieve high-efficiency power generation, reduce dependence on traditional energy, and improve energy utilization efficiency. Rainwater is purified and reused, which saves water resources and is also beneficial to environmental protection and sustainable development. In addition, the vertical greening module not only has a sunshade function, but also can purify air and rainwater, making the building have a multifunctional landscape and improving the aesthetics and ecology of the urban environment.

[0050] The above specific examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art, according to the concept of the present invention, some simple deductions, modifications or substitutions can be made.
