Description

Technical Field

[0001] This invention relates to the field of municipal road drainage, and in particular to an ecological drainage system for municipal roads. Background Technology

[0002] Municipal roads are one of the most important infrastructures for urban development. Drainage ditches and green belts are usually set up on both sides of municipal roads. At the same time, the green belts are regularly maintained by staff to beautify the environment.

[0003] Currently, with the intensification of global warming, extreme weather is more likely to occur, and some areas often experience drought or continuous rainfall. This increases the difficulty and cost of road drainage and green belt maintenance. In particular, during droughts, if water is not provided in time, green plants are prone to withering due to drought, which needs further improvement. Summary of the Invention

[0004] The purpose of this application is to provide an ecological drainage system for municipal roads that can effectively utilize water resources on both sides of the road, both diverting water from drainage ditches and nourishing green plants to balance the ecology on both sides of the road.

[0005] This application provides an ecological drainage system for municipal roads, which adopts the following technical solution:

[0006] An ecological drainage system for municipal roads includes: a first water storage tank located between a drainage ditch and a green belt, with its top connected to the bottom side of the drainage ditch via a pipe; a second water storage tank located at the bottom of the green belt, with its top connected to the side of the first water storage tank via a drainage pipe; a water storage layer located in the soil layer at the bottom of the green belt; a water intake component connected at one end to the water storage layer and extending to the bottom of the second water storage tank to introduce water into the water storage layer; and an opening and closing component located in the first water storage tank for controlling the opening and closing of the pipe and the drainage pipe.

[0007] By adopting the above technical solution, the drainage ditch itself can play a diversion role during heavy rain. With the use of the opening and closing components, the first water storage tank can divert the water from the drainage ditch into the second water storage tank, thereby further diverting the water. The water diversion components can continuously introduce water from the second water storage tank into the green belt to ensure the survival of the green plants during drought. This solution can effectively balance the ecology on both sides of the road, achieving multiple benefits.

[0008] This application further provides that the opening and closing assembly includes: a sealing plate slidably disposed on the top wall of the first water storage tank for blocking the outlet of the pipe; a compression spring with one end connected to the sealing plate and the other end fixed to the inner wall of the first water storage tank; a float slidably disposed on the inner wall of the first water storage tank in a vertical direction; a pull rope with one end connected to the sealing plate and the other end passing over a fixed pulley installed on the top wall of the first water storage tank and connected to the float; and a baffle connected to the float and used to seal the inlet of the drain pipe. When the float drives the baffle to rise to a predetermined height and releases the obstruction of the inlet of the drain pipe, the sealing plate completely seals the outlet of the pipe under the elastic force of the compression spring.

[0009] By adopting the above technical solution, during heavy rain, the water in the drainage ditch will flow through the pipe to the first water storage tank. At this time, the float will drive the baffle to rise. When the baffle rises to the point of releasing the restriction on the drainage pipe, the water in the first water storage tank will flow through the drainage pipe to the second water storage tank. At the same time, the compression spring will use its own elastic force to drive the sealing plate to block the outlet of the pipe. This cycle not only keeps the water in the first water storage tank in a dynamic balance, but also achieves the functions of diversion and nourishing the green belt.

[0010] This application further provides that: a vertical rod is vertically installed in the first water storage tank for the float to move through, and an annular limiting block is installed at a predetermined position on the outside of the vertical rod to restrict the position of the float; when the bottom of the float abuts against the annular limiting block, the sealing plate releases the restriction on the drain outlet of the pipe.

[0011] By adopting the above technical solution, the vertical rod can guide the float, making the float rise and fall more stably, while the annular limiting block can restrict the float, reducing unnecessary trouble caused by the float continuing to descend.

[0012] This application further provides that: a triangular block is installed on the side of the sealing plate near the fixed pulley, an installation rod is installed on the top of the float, and an inclined block adapted to the triangular block is fixed on the top of the installation rod.

[0013] By adopting the above technical solution, during the rising process of the floating plate, the inclined block can abut against the triangular block to drive the sealing plate to move horizontally. At the same time, this structure can play a dual guarantee role when driving the sealing plate to move, so as to reduce the impact of the compression spring's elasticity drop on the movement of the sealing plate.

[0014] This application further provides that: the drain outlet of the pipe is arranged in a strip shape, and a fixing plate with the extension direction of the drain outlet of the pipe is installed on the top wall of the first water storage tank. The fixing plate and the sealing plate are both provided with rubber edges on the side that are close to each other.

[0015] By adopting the above technical solution and setting a fixing plate and rubber edge, the sealing effect of the pipe outlet can be enhanced when the sealing plate blocks the pipe outlet.

[0016] This application further provides that the water intake assembly includes: a plurality of hollow tubes vertically installed on the top wall of the second water storage tank; and a water-absorbing rod that moves through the hollow tubes, with one end connected to the water storage layer and the other end extending to the bottom of the second water storage tank.

[0017] By adopting the above technical solution, the water-absorbing rods can absorb water in the second water storage tank and transfer the absorbed water to the water storage layer, so that the water storage layer can nourish the roots of the green plants at all times and reduce the impact of drought on the green plants.

[0018] This application further provides that: a hollow water-absorbing plate is installed at the bottom of the hollow tube, and multiple water inlet holes are provided around the bottom side of the water-absorbing plate. Multiple cotton strips with their outer ends protruding from the water inlet holes are arranged radially inside the water-absorbing plate, and the inner ends of the cotton strips are all connected to the bottom of the water-absorbing rod.

[0019] By adopting the above technical solution, the water-absorbing plate and the radial cotton strips inside the water-absorbing plate work together to increase the water absorption range on the basis of the water-absorbing stick, better nourish the green plants, and at the same time, increase the stability of the entire water-draining component.

[0020] This application further includes: a water storage tank is provided on one side of the second water storage tank; a connecting pipe is provided between the bottom of the drainage ditch and the water storage tank; a solenoid valve is provided at the opening of the connecting pipe; a liquid level monitoring device is provided in the water storage tank; both the solenoid valve and the liquid level monitoring device are electrically connected to a remote terminal; and a sprinkler pipe extending to the green belt is also provided in the water storage tank.

[0021] By adopting the above technical solution, the water storage tank can further divert water from the drainage ditch based on the first water storage tank. At the same time, the sprinkler pipe can be turned on to irrigate the green plants when needed, achieving multiple benefits in one fell swoop.

[0022] This application further includes the following configuration: a flexible hose is connected to the water outlet end of the sprinkler pipe, a spherical nozzle is installed at the end of the flexible hose, and a lifting assembly for driving the spherical nozzle to rise and fall is vertically arranged on the green belt.

[0023] By adopting the above technical solution, the spherical nozzle can increase the spraying range for green plants, and the lifting component can drive the spherical nozzle to rise and fall when needed to adapt to the irrigation of green plants with different diameter ranges.

[0024] This application further includes the following configuration: a pressure sensor is installed on the bottom wall of the second water storage tank, a pressure plate is slidably arranged above the pressure sensor and along the inner wall of the second water storage tank, a water pump electrically connected to the pressure sensor is installed in the water storage tank, and a drainage pipe extending into the second water storage tank is connected to the outlet of the water pump. When the pressure plate presses against the pressure sensor, the water pump will pump water from the water storage tank into the second water storage tank.

[0025] By adopting the above technical solution, when the pressure sensor senses the pressure of the pressure plate, it indicates that the water in the second water storage tank is close to drying up. At this time, the signal can be transmitted to the water pump, so that the water pump can pump the water in the storage tank to the second water storage tank, so as to ensure that the green plants are always in a nourished state.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] By setting up a first and a second water storage tank, which work together, the system not only diverts water from the drainage ditch during heavy rains, but also nourishes the green belts on both sides of the road during dry weather, reducing the withering of the plants. This solution can effectively balance the use of water resources.

[0028] By setting up a water storage tank, not only can the drainage ditch be further diverted, but the water in the second water storage tank can also be replenished when needed to ensure uninterrupted nourishment for the green plants. Furthermore, the irrigation of the green plants can be further enhanced through the sprinkler pipes, achieving multiple benefits in one fell swoop. Attached Figure Description

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses an ecological drainage system for municipal roads, such as... Figure 1 and Figure 2 As shown, it includes: a drainage ditch 1 and a green belt 2 set on both sides of the municipal road, with the drainage ditch 1 located between the road and the green belt 2. A first water storage tank 31 is set underground between the drainage ditch 1 and the green belt 2. The top of the first water storage tank 31 is connected to the bottom side wall of the drainage ditch 1 through a pipe 11. When it rains heavily, the water in the drainage ditch 1 can be diverted to the first water storage tank 31 through the pipe 11 to reduce the pressure on the drainage ditch 1.

[0034] A second water storage tank 32 is installed underground at the bottom of the green belt 2. The side wall of the first water storage tank 31 is connected to the second water storage tank 32 through a drainage pipe 12. When the water level in the first water storage tank 31 rises to a predetermined height, the water will be discharged into the second water storage tank 32 through the drainage pipe 12. A water storage layer 21 is laid in the soil layer at the bottom of the green belt 2. In this embodiment, the water storage layer 21 can be made of sponge. A water diversion component is also installed in the second water storage tank 32. One end of the water diversion component is connected to the water storage layer 21, and the other end extends to the bottom wall of the second water storage tank 32. The advantage of this arrangement is that the water diversion component can divert the water in the second water storage tank 32 into the water storage layer 21, so that the water storage layer 21 can continuously nourish the soil at the bottom of the green belt 2 to ensure that the green plants are in a living state.

[0035] In addition, an opening and closing assembly is provided in the first water storage tank 31. The opening and closing assembly can control the drainage in the pipe 11 and the drain pipe 12. In this embodiment, the opening and closing assembly includes a sealing plate 33 slidably disposed on the top wall of the first water storage tank 31. The sealing plate 33 is used to block the outlet of the pipe 11. It should be noted that the outlet of the pipe 11 is strip-shaped. A compression spring 34 is installed on the side of the sealing plate 33 away from the pipe 11. The end of the compression spring 34 away from the sealing plate 33 is fixed on the inner wall of the first water storage tank 31, and the compression spring 34 applies an elastic force to the sealing plate 33 to slide toward the outlet of the pipe 11.

[0036] In addition, a float plate 35 is slidably installed on the inner wall of the first water storage tank 31 in the vertical direction. A baffle 37 for sealing the inlet of the drain pipe 12 is also fixed on the float plate 35. A pull rope 36 is connected to the top of the float plate 35. A fixed pulley 38 is also installed on the top wall of the first water storage tank 31. The fixed pulley 38 is located directly above the float plate 35. The end of the pull rope 36 passes around the fixed pulley 38 and is connected to the sealing plate 33. When the water level in the first water storage tank 31 rises, the float plate 35 will drive the baffle 37 to rise to a predetermined height, thereby removing the obstruction of the inlet of the drain pipe 12. At this time, the sealing plate 33 will slide under the elastic force of the compression spring 34 and completely seal the drain outlet of the pipe 11.

[0037] Conversely, when the water level in the first reservoir 31 drops, the float 35 descends, causing the baffle 37 to block the inlet of the drain pipe 12. At this time, the sealing plate 33 slides under the pull of the rope 36 and releases the blockage of the drain outlet of the pipe 11. Through this scheme, the dynamic balance of the water level in the first reservoir 31 can be automatically achieved.

[0038] To reduce the excessive descent of the float 35 due to the drop in water level in the first reservoir 31, in this embodiment, a vertical rod 39 is vertically installed in the first reservoir 31, and the float 35 is movably sleeved on the vertical rod 39. An annular limiting block 391 is installed at a predetermined position on the outside of the vertical rod 39. When the bottom of the float 35 abuts against the annular limiting block 391, the baffle 37 can block the inlet of the drain pipe 12, and the sealing plate 33 can just release the restriction on the drain outlet of the pipe 11.

[0039] To ensure the smooth sliding of the sealing plate 33, a triangular block 330 is installed on the side of the sealing plate 33 near the fixed pulley 38, and an installation rod 351 is vertically installed on the top of the float plate 35. An inclined block 352 is installed on the top of the installation rod 351. The inclined block 352 and the triangular block 330 can be matched. Under normal conditions, the inclined block 352 and the triangular block 330 are in contact with each other.

[0040] It should be noted that the weight of the float 35, baffle 37, mounting rod 351, and tilting block 352 is greater than the elastic force of the compression spring 34. The specific weight is set according to the actual situation. The frictional resistance between the pull rope 36, the float 35, and the sealing plate 33 is negligible. With this scheme, when there is a lot of water in the drainage ditch 1, the water can be automatically diverted into the first water storage tank 31 and the second water storage tank 32 to achieve the diversion of rainwater on both sides of the road. At the same time, during drought, the water diversion component can divert the water in the second water storage tank 32 into the water storage layer 21 to nourish the green belt 2, thereby ensuring the growth needs of the green plants.

[0041] To enhance the sealing effect of the outlet of pipe 11, a fixing plate 30 is installed on the top wall of the first water storage tank 31. The extension direction of the fixing plate 30 is consistent with the extension direction of the outlet of pipe 11. At the same time, rubber edges are provided on the side where the fixing plate 30 and the sealing plate 33 are close to each other. The rubber edges themselves have good elasticity, which can further enhance the sealing effect of pipe 11 when the fixing plate 30 and the sealing plate 33 are in contact.

[0042] In this embodiment, the water intake component includes: a plurality of hollow tubes 22 vertically installed on the top wall of the second water storage tank 32, the hollow tubes 22 being evenly distributed, and a water-absorbing rod 23 being provided inside the hollow tube 22 along its extension direction, the top end of the water-absorbing rod 23 being connected to the water storage layer 21, and the bottom end of the water-absorbing rod 23 extending to the bottom wall of the second water storage tank 32.

[0043] To further increase the water intake range of the water intake assembly, a hollow water absorption plate 24 is installed at the bottom of the hollow tube 22, and multiple water inlet holes are opened on the bottom side of the water absorption plate 24. Multiple cotton strips are arranged inside the water absorption plate 24 in a radial pattern, with one end connected to the bottom of the water absorption rod 23 and the other end protruding from the water inlet hole, so as to better absorb water and reduce the entry of debris into the water absorption plate 24.

[0044] A water storage tank 4 is also provided in the soil layer on one side of the second water storage tank 32. A connecting pipe 41 is provided between the bottom of the drainage ditch 1 and the water storage tank 4. A solenoid valve is provided at the end of the connecting pipe 41 located in the drainage ditch 1. A liquid level monitoring device is provided in the water storage tank 4. The liquid level monitoring device used in this embodiment is a commonly available device on the market. As long as the function can be realized, it is acceptable. There are many types of such devices, which will not be described in detail here.

[0045] In addition, the liquid level monitoring device, solenoid valve and remote terminal in this embodiment are all electrically connected. When there is water in the drainage ditch 1 and the liquid level monitoring device detects that the liquid level in the water storage tank 4 is lower than the preset value, it will transmit a signal to the solenoid valve. The solenoid valve will open the connecting pipe 41 so that the water in the drainage ditch 1 can be discharged into the water storage tank 4 for storage through the connecting pipe 41.

[0046] Considering that the green belt 2 sometimes needs to be watered and that it is necessary to purify the dust and environment around the green belt 2, a sprinkler pipe 42 is installed in the water storage tank 4. One end of the sprinkler pipe 42, away from the water storage tank 4, extends out from the green belt 2. In addition, a hose 43 is connected to the water outlet end of the sprinkler pipe 42, and a spherical nozzle 44 is installed at the end of the hose 43. A lifting assembly for driving the spherical nozzle 44 to rise and fall is vertically installed on the green belt 2. In this embodiment, the lifting assembly can be a cylinder.

[0047] When it is necessary to water the green belt 2 and purify the surrounding environment, the switch of the control sprinkler pipe 42 can be turned on to spray water on the green plants in the green belt 2. At the same time, the cylinder can be turned on to drive the ball nozzle 44 to rise and fall to adapt to the green plants at different distances from the sprinkler pipe 42, thereby expanding the watering range.

[0048] Considering the situation where the water in the drainage ditch 1 is low and the second water storage tank 32 cannot be replenished in time, a pressure sensor 5 is installed on the bottom wall of the second water storage tank 32. A pressure plate 51 is slidably installed above the pressure sensor 5 and on the inner wall of the second water storage tank 32. A water pump 52 electrically connected to the pressure sensor 5 is installed in the water storage tank 4. The outlet of the water pump 52 is connected to a drainage pipe 53 extending into the second water storage tank 32.

[0049] When the water level in the second reservoir 32 drops to near the bottom wall, the pressure plate 51 will press against the pressure sensor 5, and the pressure sensor 5 will transmit a signal to the water pump 52. At this time, the water pump 52 will start and pump the water in the reservoir 4 into the second reservoir 32 through the drainage pipe 53 to ensure that the second reservoir 32 provides normal nourishment to the green belt 2.

[0050] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
