Description

Technical Field

[0001] The present application relates to the technical field of municipal engineering, and in particular to a circulating water-saving municipal greening landscape system. Background Art

[0002] With the continuous development of municipal engineering, more and more cities are moving towards sponge urbanization, especially in cities with heavy rainfall in summer or rainy season. Discharging rainwater in time to reduce flood disasters and recycling rainwater to save energy are both directions in which sponge cities are constantly optimizing and breaking through.

[0003] Municipal engineering usually includes road engineering. Multiple rainwater wells are usually set up on the road near the sidewalk or green belt. There is a certain distance between adjacent rainwater wells. The bottom of the rainwater well is connected to the drainage main line. Rainwater grates are installed on the rainwater well to reduce the falling of fallen leaves and pedestrians. Rainwater can be discharged in time through the rainwater well to reduce road waterlogging.

[0004] In addition, green belts are usually set up between some two-way lanes. Plants planted on the green belts can serve as municipal green landscapes for passers-by to appreciate, and can absorb some exhaust gas to reduce air pollution. However, in order to maintain the vitality of the plants on the green belts, a watering cannon fleet is usually required to water the green belts.

[0005] However, in the related art, during rainfall, most of the rainwater on the highway is drained through rainwater wells and drainage mains, and this part of the water resources is not well used for irrigation of green belts, which needs further improvement. Summary of the Invention

[0006] In order to store rainwater on roads during rainfall and use it for irrigation of green belts, the present application provides a recycling and water-saving municipal greening landscape system.

[0007] This application provides a water-saving municipal greening landscape system that adopts the following technical solutions:

[0008] A water-saving municipal greening landscape system includes a highway and a green belt arranged on one side of the highway. The highway is provided with a plurality of rainwater wells spaced apart along its extension direction. The rainwater wells are provided with sealing components capable of opening and closing the openings of the rainwater wells.

[0009] A curbstone is provided between the green belt and the highway, and a plurality of water inlets are provided on the curbstone at intervals along the extending direction of the highway;

[0010] A seepage box and a water storage box are buried in the green belt. The seepage box is connected to the water inlet. A seepage hole is opened on the side wall of the seepage box. A first overflow port connected to the water storage box is also opened on the side wall of the seepage box. A driving component for driving a closing component to close or release the opening of the rainwater well is provided on the green belt.

[0011] The driving component drives the closing component to release the sealing of the rainwater well opening. The green belt is provided with a spraying component for irrigating vegetation and connected to the water tank.

[0012] By adopting the above technical solution, when the rainwater is small, the rainwater well is closed by the closing component, so that the water flows first through the water inlet into the seepage tank for storage, reducing the waste caused by water flowing away through the rainwater well;

[0013] The water in the seepage tank can be replenished into the soil of the green belt through the seepage holes when there is no rainfall. When the rainfall is heavy, the water in the seepage tank can be replenished into the water holding tank through the first overflow port. The water in the water holding tank can be used to irrigate the green belt through the spraying assembly later. When the water level in the seepage tank and the water holding tank continues to rise, the closing assembly is unlocked by the driving assembly. At this time, the water can be quickly discharged through the rainwater to reduce the occurrence of flood disasters.

[0014] Optionally, the spray assembly includes a water pump arranged in the water tank, a main pipe connected to the water pump, and multiple branch pipes connected to the main pipe. The multiple branch pipes are arranged at intervals along the extension direction of the green belt, and a nozzle is provided at one end of the branch pipe away from the water tank.

[0015] By adopting the above technical solution, the water flow in the water tank can be drawn to the main pipeline through the water pump, and then to the branch pipeline, and sprayed out from the nozzle located above the soil layer of the green belt in the branch pipeline to irrigate the vegetation on the green belt.

[0016] Optionally, a rain grate for closing the rainwater well opening is provided on the highway, and the closing assembly includes a closing plate arranged at the bottom of the rainwater grate, and a plurality of long water-permeable holes are provided on the closing plate, and a hollow shielding strip is vertically slidably connected in the long water-permeable holes, and a closing edge is provided on the top of the shielding strip for abutting against the closing plate to close the long water-permeable holes, and a water inlet hole is provided on the side wall of the shielding strip, and the driving assembly is used to drive the shielding strip to move in the vertical direction.

[0017] By adopting the above technical solution, a rain grate is set up to isolate larger stones and fallen leaves. When the closing component is unlocked, water flows through the rain grate and the long water-permeable hole into the rainwater well; the shielding strip is inserted into the long water-permeable hole, and the closing plate and the closing edge offset each other to reduce water leakage; when the shielding strip is driven to move by the driving component, so that the closing edge is separated from the closing plate and the water inlet is exposed, water can flow downward from the water inlet through the closing plate.

[0018] Optionally, a water storage cylinder is provided in the rainwater well, the bottom of the water storage cylinder is closed, a second overflow port is opened on the side wall of the water storage cylinder, and a return pipe is provided between the water storage cylinder and the water tank, and the return pipe is used to introduce the water flow in the water storage cylinder into the water tank.

[0019] By adopting the above technical solution, rainwater entering the rainwater well can be collected by the water storage cylinder. When the water level in the storage tank drops, the water flow in the water storage cylinder can replenish the storage tank, further improving the water-saving effect. When the rainfall is heavy and the water level in the water storage cylinder is high, the water flow can be discharged into the rainwater well through the second overflow port, reducing water accumulation on the road.

[0020] Optionally, the driving assembly includes a sliding bar that slides horizontally on the curbstone, with both ends of the sliding bar located in a rainwater well and a seepage box respectively. The end of the sliding bar located in the rainwater well has convex bars fixed at intervals along the length direction for abutting against the shielding bar. The convex bar includes a guide surface that abuts against the shielding bar. When the sliding bar moves away from the green belt, the convex bar pushes the shielding bar up.

[0021] By adopting the above technical solution, when the sliding bar slides, the convex bar drives the shielding bar to move through the guide surface, so that water can enter from the water inlet hole.

[0022] Optionally, the driving assembly includes a float located in the seepage box, a guide block is fixed on the top of the float, the guide block includes a guide surface that abuts against the end of the slide bar, when the float rises, the guide surface pushes the slide bar to move, and a return spring is arranged between the end of the slide bar away from the guide block and the inner wall of the water storage cylinder.

[0023] By adopting the above technical solution, when the water level in the seepage box rises, the float plate also rises, and the guide surface of the guide block can push the slide bar to move. When the water level in the seepage box drops, the elastic force of the reset spring allows the slide bar to reset and the closing plate to be closed again.

[0024] Optionally, the slide bar includes a first slide bar located in the rainwater well and a second slide bar sliding on the curbstone, the first slide bar and the second slide bar are abutted, and the water storage cylinder, the closing plate and the rainwater grate are detachably connected to the rainwater well.

[0025] By adopting the above technical solution, the water storage cylinder, the closing plate and the rain grate can be detachably connected to the road, so that the three can be removed for cleaning. Moreover, since the first slide bar and the second slide bar are transmitted by abutment, when the water storage cylinder is removed, the first slide bar and the second slide bar can be directly separated, which is convenient for disassembly.

[0026] Optionally, a support edge for the bottom of the water storage cylinder to abut is fixedly connected to the inner wall of the rainwater well.

[0027] By adopting the above technical solution, the support edge can provide support for the water storage cylinder and play a positioning role when installing the water storage cylinder.

[0028] In summary, this application has at least one of the following beneficial effects:

[0029] 1. When it rains, rainwater first enters the seepage tank and water storage tank in the green belt to irrigate the green belt, reducing the waste of rainwater on the road;

[0030] 2. When the rainfall is heavy and the infiltration tank and the water storage tank are saturated, the rainwater well can be opened to drain the rainwater and reduce the occurrence of waterlogging on the road;

[0031] 3. The water storage cylinder is provided to further store water, and a return pipe is provided between the water storage cylinder and the water storage tank, so that the water flow in the water storage cylinder can be replenished into the water storage tank, which further saves water.

[0032] 4. The water tank can be disassembled to facilitate cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following is combined with Figure 1-4 This application is described in further detail.

[0039] The embodiment of the present application discloses a circulating water-saving municipal greening landscape system, referring to Figure 1 and Figure 2 A recycling and water-saving municipal greening landscape system includes a green belt 2 and a highway 1 arranged on both sides of the green belt 2. The extension direction of the highway 1 and the green belt 2 is the same. The green belt 2 is used to separate the round-trip lanes, and by planting vegetation and trees on the green belt 2, it serves as a green landscape. The trees and vegetation can also absorb exhaust gas.

[0040] Reference Figure 1 and Figure 2 A curbstone 3 is set between the green belt 2 and the highway 1. The extension direction of the curbstone 3 is also consistent with the extension direction of the highway 1 and the green belt 2. The curbstone 3 separates the highway 1 and the green belt 2, reducing the loss of soil on the green belt 2.

[0041] Highway 1 is equipped with multiple rainwater wells 11 spaced apart along its length. The bottoms of these wells 11 are connected to drainage pipes buried within the highway 1, draining rainwater from these wells. These wells 11 are located on the side of highway 1 near the curbstone 3. The curbstone 3 is also equipped with multiple water inlets 31 spaced evenly apart along its length. The bottoms of these inlets 31 are flush with the surface of highway 1, and highway 1 is angled slightly toward the green belt 2. This allows rainwater from the road surface to flow through these inlets 31 into the green belt 2 or into the rainwater wells 11 during rainy days, minimizing waterlogging on highway 1. Water entering the green belt 2 through these inlets 31 can be stored and used for irrigation.

[0042] A sealing assembly is provided within the rainwater well 11 for sealing the opening of the rainwater well 11. When the sealing assembly seals the opening of the rainwater well 11, less water is discharged from the rainwater well 11, allowing more water to flow into the green belt 2, thereby achieving a better water-saving effect. A driving assembly is provided within the green belt 2 to drive the sealing assembly to open and close the opening of the rainwater well 11. When there is heavy rainfall, or when the retained water flow in the green belt 2 is saturated, water on the highway 1 can be discharged through the rainwater well 11.

[0043] Reference Figure 2 and Figure 3 On the side of the curbstone 3 close to the highway 1, a filter screen 33 covering the opening of the water inlet 31 is detachably connected to reduce the amount of garbage entering the green belt 2. A seepage tank 21 located higher and close to the curbstone 3 is buried in the green belt 2, as well as a water storage tank 23 located lower in the middle of the green belt 2. An inlet pipe 32 is connected between the seepage tank 21 and the water inlet 31, allowing water on the highway 1 to enter the seepage tank 21 through the inlet pipe 32. Seepage holes are evenly distributed on the sidewalls of the seepage tank 21. When it is not raining, the water in the seepage tank 21 can be replenished into the green belt 2 by slow infiltration to replenish moisture. There are multiple seepage boxes 21 arranged along a long strip or along the extension direction of the green belt 2. A first overflow port 211 is opened at a higher position on one side wall of the seepage box 21. An overflow pipe 212 is connected between the first overflow port 211 and the water storage tank 23, so that when the rainfall is heavy, the water can flow through the overflow pipe 212 to the water storage tank 23 for storage.

[0044] The water tank 23 is also in the shape of a long strip or is provided in multiple pieces along the extension direction of the highway 1. A spraying assembly is also provided in the green belt 2, which can use the water source in the water tank 23 to irrigate the green belt 2. Specifically, the spraying assembly includes a water pump 231 provided in the water tank 23, and a main pipe 232 connected to the water pump 231. The main pipe 232 is provided along the length direction of the green belt 2 and buried in the soil layer of the green belt 2. The spraying assembly also includes a plurality of parallel branch pipes 233. The branch pipes 233 are provided at equal intervals along the length direction of the main pipe 232 and are connected to the main pipe 232. One end of the branch pipe 233 passes through the soil layer of the green belt 2 and is provided with a nozzle 234. When the water pump 231 is started, the water flow in the water tank 23 can be sprayed through the nozzle 234 to irrigate the green belt 2.

[0045] Reference Figure 2 and Figure 3A rain grate 12 is provided on the highway 1 to cover the opening of the rainwater well 11. Specifically, a trough 111 for the rainwater grate 12 to abut against is provided on the side wall of the rainwater well 11 near the opening, so that the rainwater grate 12 can be limited and disassembled. The rainwater grate 12 can retain garbage and large pieces of gravel, so that the water flow on the highway 1 can better enter the rainwater well 11. A support edge 112 is fixedly connected to the inner wall of the rainwater well 11, and a water storage cylinder 14 is detachably connected to the rainwater well 11. The bottom of the water storage cylinder 14 is closed and is used to abut against the support edge 112, so that the water storage cylinder 14 can be stably fixed in the rainwater well 11. When rainwater enters the rainwater well 11, the rainwater can be stored in the water storage cylinder 14. A second overflow port 143 is provided at a higher position on the side wall of the water storage cylinder 14 , and an overflow channel is provided on the inner wall of the rainwater well 11 . When the water level in the water storage cylinder 14 is high, rainwater can be discharged through the second overflow port 143 and the overflow channel.

[0046] Reference Figure 2 and Figure 3 A return pipe 113 is provided on the side wall of the rainwater well 11, and the return pipe 113 is connected to the water tank 23. When the water level in the water tank 23 drops, the water in the rainwater well 11 can flow into the water tank 23 through the return pipe 113, thereby achieving a better water-saving effect.

[0047] Reference Figure 3 and Figure 4 The closure assembly includes a closure plate 13 that is removably mounted within the water storage cylinder 14. The closure plate 13 is provided with a plurality of parallel long water-permeable holes 131. A shielding bar 132 is slidably connected within the long water-permeable holes 131, which is used to close the long water-permeable holes 131. The shielding bar 132 is hollow and has a water inlet hole 134 defined in its sidewall. A sealing edge 133 is fixedly connected to one end of the shielding bar 132 located above the closure plate 13. The sealing edge 133 is used to abut against the closure plate 13, thereby closing the long water-permeable holes 131. The drive assembly is used to drive the shielding bar 132 to move, so that the water inlet hole 134 is located outside the long water-permeable holes 131, thereby allowing water to drain through the shielding bar 132.

[0048] The drive assembly includes a slide bar 15 slidably connected to the curbstone 3. The slide bar 15 includes a first slide bar 151 located within the rainwater well 11 and a second slide bar 152 located within the seepage tank 21. The first slide bar 151 and the second slide bar 152 abut each other. The drive assembly also includes a floating plate 22 located within the seepage tank 21. A guide block 221 is fixedly connected to the floating plate 22. The guide block 221 includes a guide surface that abuts the slide bar 15. When the floating plate 22 rises due to the water flow, the guide block 221 pushes the slide bar 15 to move. The slide bar 15 can then drive the shielding bar 132 upward, thereby releasing the seal of the closure plate 13.

[0049] Reference Figure 3 and Figure 4A horizontal support bar 141 is fixedly connected to the water storage cylinder 14, and the second slide bar 152 slides on the support bar 141. A return spring 142 is fixedly connected between the inner wall of the water storage cylinder 14 away from the green belt 2 and the first slide bar 151. A plurality of convex strips 153 are fixedly connected to the top surface of the first slide bar 151 along the length direction. The convex strip 153 includes a guide surface that is opposed to the shielding strip 132. When the slide bar 15 slides toward the return spring 142 and compresses the return spring 142, the guide surface can push the shielding strip 132 to move, thereby facilitating the opening of the closing plate 13 for water to flow down.

[0050] Reference Figure 2 and Figure 3 The water storage cylinder 14, the closing plate 13, the first slide bar 151 and the rainwater grate 12 are all detachable, which is convenient for regular disassembly and cleaning. The cross-section of the rainwater well 11 is rectangular, and a support edge 112 is provided for positioning the water storage cylinder 14. During installation, the first slide bar 151 and the second slide bar 152, as well as the drainage hole of the water storage cylinder 14 and the return pipe 113 can be easily aligned.

[0051] The implementation principle of a recycling and water-saving municipal greening landscape system in the embodiment of the present application is as follows: when the rainfall is small, the closing plate 13 closes the rainwater well 11, and the water on the highway 1 enters the seepage tank 21 through the water inlet 31 for storage, and the water in the seepage tank 21 slowly seeps into the soil in the later stage; when the rainfall is heavy, the water level in the seepage tank 21 rises, so that part of the water flows through the first overflow port 211 to be replenished into the water storage tank 23 for storage, and the rising water level in the seepage tank 21 pushes the floating plate 22 to rise, and the guide block 221 on the floating plate 22 pushes the slide 15 to move, thereby unlocking the closing plate 13, so that part of the water flows from the rainwater well 11 or is collected through the water storage cylinder 14. The water in the water storage cylinder 14 can replenish the middle water tank 23 or be discharged through the second overflow port 143, thereby reducing flood disasters on the highway 1, and the water in the water storage tank 23 can be used to irrigate the green belt 2 through the spraying assembly.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
