Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a self-cleaning and maintenance system based on sponge city facilities. Background Art

[0002] 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". The international general term is "low impact development rainwater system construction". When it rains, it absorbs, stores, seeps, and purifies water, and when needed, the stored water is released and utilized to realize the free migration of rainwater in the city. Starting from ecosystem services, the core of the sponge city is to build water ecological infrastructure across scales and combine various specific technologies to build water ecological infrastructure.

[0003] In the operation scenario of the sponge city, the dust reduction operation of urban roads is often carried out by using the collected rainwater. For example, the Chinese invention patent with the application number CN202110509959.8 discloses a multifunctional lighting street lamp based on the sponge city, which includes a column. Both sides of the top of the column are connected with support rods. One side of the bottom of the support rod is fixedly provided with a lighting lamp, and the other side of the bottom is fixedly provided with a nozzle. The top of the support rod is provided with a power supply component for supplying power to the lighting lamp. The inside of the column is a cavity structure and its bottom end is communicated with a water storage tank. The water storage tank is fixedly arranged on the ground. An inlet is opened at the middle position of the top of the column, and a coarse filter screen matching its size is arranged at the inlet. One side of the outside of the column is fixedly provided with a dust monitor, a water pump and a controller. The dust monitor and the water pump are both electrically connected with the controller. The controller is electrically connected with an external power supply. The water inlet end of the water pump is connected with a water inlet pipe extending into the water storage tank, and its water outlet end is connected with a water outlet pipe communicated with the nozzle. When it rains, the rainwater is filtered by the coarse filter screen and stored in the water storage tank from the column. When the dust monitor detects that the dust in the air is higher than the set value, the dust monitor transmits the signal of too high dust to the controller. After receiving the signal, the controller starts the water pump to pump the water stored in the water storage tank to the nozzle for spraying to achieve the effect of dust reduction. When the value detected by the dust monitor is lower than the set value, the dust monitor transmits the signal to the controller, and the controller closes the water pump after receiving the signal. This solves the problem of the single function of the lighting street lamp, and can store the rainwater well when it rains for dust reduction when the dust in the air is too high, which conforms to the development concept of building a sponge city. However, there are still deficiencies, which are described as follows:

[0004] The above-mentioned lighting street lamp sets the nozzle structure towards the road surface. Such a structural setting will cause the water mist to be concentrated and dispersed towards the sidewalk and non-motor vehicle lane area. Pedestrians and non-motor vehicle drivers are easily wetted by the water mist when passing through the street lamp area, affecting their convenience of passage.

[0005] Therefore, how to reduce the setting to prevent the water mist sprayed by the nozzle from drifting to the sidewalk and non-motorized vehicle lane area is a technical problem that needs to be solved urgently in the prior art. Utility Model Content

[0006] The purpose of the utility model is to provide a self-cleaning and maintenance system based on sponge city facilities in response to the problem that the existing lighting street lamps have a nozzle structure set to face the road surface.

Pedestrians and non-motor vehicle drivers are easily wetted by the water mist when passing through the street lamp area, affecting their travel convenience.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0036] In the description of the present utility model, it should be noted that the orientation or position relationship indicated by the terms "upper", "lower", etc. is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the invention product is usually placed when in use, or the orientation or position relationship commonly understood by those skilled in the art. Such terms are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0037] Example 1: Figures 1 to 3 As shown, the utility model discloses a self-cleaning and maintenance system based on sponge city facilities, comprising a water storage tank 1, a water supply component 2, a spray component 3 and a street lamp 4, wherein the street lamp 4 comprises a main lamp pole 5, a lateral lamp pole 6 and a lighting lamp 7, wherein the lateral lamp pole 6 extends in the direction of the lane, and the lighting lamp 7 is arranged at the end of the lateral lamp pole 6.

[0038] The spray component 3 includes a nozzle 8, a first air supply pipe 9 and an air supply pump 10. The first air supply pipe 9 is connected to the lateral lamp pole 6, and the first air supply pipe 9 is arranged on the side away from the light-emitting surface of the lighting lamp 7. The air supply pump 10 is connected to the first air supply pipe 9, and the air supply pump 10 is used to transport pressurized air into the first air supply pipe 9.

[0039] The spray head 8 is arranged at the end of the first air supply pipe 9, and the spraying direction of the spray head 8 is set towards the axis of the first air supply pipe 9. The water supply component 2 is connected to the spray head 8, and the water supply component 2 is used to convey the rainwater collected in the water storage tank 1 to the spray head 8.

[0040] By adopting the self-cleaning and maintenance system based on sponge city facilities of the present invention, setting the spraying direction of the spray head 8 towards the axis of the first air supply pipe 9, and using the high-pressure air flow blown out in the first air supply pipe 9, the water mist sprayed out by the spray head 8 can be blown towards the middle area of the road, thus avoiding the water mist from spreading on the sidewalk and non-motor vehicle lane and ensuring the convenience of pedestrians and non-motor vehicles passing through. Moreover, with this structural setting, it can also prevent the water mist sprayed out by the spray head 8 from spreading to the light-emitting area of the lighting lamp 7 and ensure the lighting effect of the street lamp 4.

[0041] Specifically, in this embodiment, the water supply component 2 includes a water supply pipe and a water pump. When the water pump operates, it extracts the rainwater stored in the water storage tank 1 and conveys it along the water supply pipe to the spray head 8. After the rainwater is sprayed out by the spray head 8, it forms a water mist state, and the high-pressure air flow blown out by the first air supply pipe 9 blows the water mist towards the middle area of the road.

[0042] As a preferred implementation scheme, on the basis of the above method, further, the central axis of the first air supply pipe 9 forms an acute angle with the central axis of the main lamp post 5 above the side lamp post 6, and the central axis of the side lamp post 6 is parallel to the central axis of the first air supply pipe 9.

[0043] In this embodiment, it is considered that when a vehicle quickly passes through the lane, the air flow rate within the lane range will increase. Under the action of the pressure difference, the air within the lane range will flow from top to bottom. When the spray head 8 sprays out water mist, it will quickly disperse towards the lane under the drive of the air flow, which is not conducive to the water mist particles adsorbing dust particles in the air. Based on this, in this embodiment, the central axis of the first air supply pipe 9 forms an acute angle with the central axis of the main lamp post 5 above the side lamp post 6. With such a structural setting, the high-pressure air flow can blow the water mist sprayed out by the spray head 8 obliquely upwards, so that the residence time of the water mist in the air can be extended. Furthermore, the water mist particles can more fully absorb the dust particles in the air, improving the dust reduction and dust removal effect of the present invention.

[0044] As a preferred embodiment, on the basis of the above method, further, the air supply pump 10 is connected to the main lamp post 5, and the air supply pump 10 is located above the side lamp post 6. With this structural arrangement, it is possible to prevent rainwater from flowing back into the air supply pump 10 along the first air supply pipe 9, reducing the risk of damage to the air supply pump 10 due to water ingress and improving the reliability of the present invention in actual use.

[0045] Embodiment 2: As Figures 1 to 3 shown, for a self-cleaning and maintenance system based on sponge city facilities according to the present invention, on the basis of the above method, further, the length of the first air supply pipe 9 is less than the length of the side lamp post 6, and the end of the first air supply pipe 9 is arranged to avoid the area of the lighting lamp 7. With this structural arrangement, when the water mist blown by the high-pressure air flow passes through the area of the lighting lamp 7, it can take away a part of the heat generated by the lighting lamp 7, thus extending the service life of the lighting lamp 7 to a certain extent and improving the practicality of the present invention in actual use.

[0046] As a preferred embodiment, on the basis of the above method, further, a shielding plate 11 is arranged in the area of the side lamp post 6 corresponding to the lighting lamp 7. The shielding plates 11 are symmetrically arranged on the left and right sides of the side lamp post 6. The shielding plate 11 is used to prevent the water mist sprayed by the nozzle 8 from diffusing towards the light-emitting area of the lighting lamp 7. With this structural arrangement, it further avoids the diffusion of the water mist towards the light-emitting area of the lighting lamp 7, ensuring the lighting effect of the street lamp 4.

[0047] As a preferred embodiment, on the basis of the above method, further, an included angle is formed by the extension lines of the central axes of the two shielding plates 11. With this structural arrangement, it is possible to prevent water mist from accumulating on the shielding plate 11 to form water droplets and dripping onto the road surface, avoiding pedestrians and non-motor vehicle drivers from being easily wetted by the water droplets when passing through the area of the street lamp 4, thereby further improving the convenience of their passage.

[0048] Embodiment 3: As Figure 1 and Figure 2 shown, for a self-cleaning and maintenance system based on sponge city facilities according to the present invention, on the basis of the above method, further, a solar panel 12 is also arranged on the main lamp post 5.

[0049] As a preferred embodiment, on the basis of the above method, further, a second air supply pipe 13 is also connected to the first air supply pipe 9. The extension line of the central axis of the second air supply pipe 13 passes through the surface of the solar panel 12. A three-way valve 14 is provided between the second air supply pipe 13 and the first air supply pipe 9. The three-way valve 14 has a first state and a second state. In the first state of the three-way valve 14, the air supply pump 10 conveys the pressurized air into the first air supply pipe 9, and the air flows toward the end side of the first air supply pipe 9. In the second state of the three-way valve 14, the air supply pump 10 conveys the pressurized air into the second air supply pipe 13, and the air flows toward the end side of the second air supply pipe 13.

[0050] Specifically, in this embodiment, the switching between the first state and the second state of the three-way valve 14 is electrically controlled. In the second state of the three-way valve 14 in this embodiment, high-pressure gas can be blown against the surface of the solar panel 12, so that the dust deposited on the surface of the solar panel 12 can fall off under the action of the air flow, ensuring the power generation efficiency of the solar panel 12.

[0051] As a preferred embodiment, on the basis of the above method, further, the extension line of the central axis of the second air supply pipe 13 is located on the side of the solar panel 12 close to the main lamp post 5, and the extension line of the central axis of the second air supply pipe 13 forms an obtuse angle with the surface of the solar panel 12. With this structural arrangement, the energy loss after the high-pressure air flow contacts the solar panel 12 can be reduced, the air flow velocity on the solar panel 12 can be made faster, so that the dust deposited on the surface of the solar panel 12 can fall off more thoroughly, thus improving the cleaning effect on the solar panel 12.

[0052] As a preferred embodiment, on the basis of the above method, further, the cross-section of the second air supply pipe 13 is arranged in a flat structure. With this structural arrangement, the air flow velocity blown to the surface of the solar panel 12 can be increased, so as to further improve the cleaning effect on the solar panel 12.

[0053] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
