Description

Technical Field

[0001] This application relates to the technical field of road environmental protection, and in particular to an environmentally friendly structure for highways. Background Technology

[0002] Highways are roads specifically designed for high-speed automobile travel. Green belts are usually installed between the northbound and southbound lanes of highways. On the one hand, the green belts separate the northbound and southbound lanes of the highway, reducing driver fatigue. On the other hand, as an environmental protection structure of highways, the green belts can absorb vehicle exhaust and purify the air along the highway.

[0003] Chinese patent CN109252470A discloses a green median strip for highways, which includes a median strip base. The median strip base is composed of several U-shaped channel units arranged end to end. Each U-shaped channel unit has a water storage layer, a soil layer and a green vegetation layer arranged from bottom to top. A water storage channel connects the top of the U-shaped channel unit to the water storage layer. Rainwater flows into the water storage layer from the water storage channel. The water stored in the water storage layer can supply water to the green vegetation layer.

[0004] The above-mentioned technical solution, which stores water through water storage channels and supplies water through water storage layers, can only provide water resources to the green vegetation layer in the initial stage. It is also highly dependent on rainy days and cannot provide water resources to the green vegetation layer stably in the long term, which is not conducive to the long-term environmental protection construction of highways. Summary of the Invention

[0005] In order to provide a long-term and stable water supply to the green vegetation layer of highways, this application provides an environmentally friendly structure for highways.

[0006] This application provides an environmentally friendly highway structure, which adopts the following technical solution:

[0007] An environmentally friendly highway structure includes multiple U-shaped channel bases connected end-to-end. Each channel base is used for planting greenery. Water flow holes are provided at the bottom of each channel base. Between adjacent channel bases, the water flow holes of one channel base are connected to the water flow holes of the other. A water pump is connected to the water flow holes of the first channel base, and the water pump is connected to a water tank. The last channel base is connected to the water tank via a pipe. The water tank is used to store water. A rainwater collection hole is provided between the top of each channel base and the water flow holes. A water supply hole is provided inside each channel base for supplying water. An adjustment component is provided on each channel base to adjust the water supply hole and the water flow holes for opening or closing. When the channel base is short of water, the adjustment component opens the water supply hole and closes the water flow hole. When the channel base contains water, the adjustment component closes the water supply hole and opens the water flow hole.

[0008] By adopting the above technical solution, water is stored in a water tank, and a water pump draws the water from the tank into the water flow holes at the beginning of the channel base. The water flows along the water flow holes connected to multiple channel bases and returns to the water tank through pipes from the water flow holes at the end of the channel base. This allows the water to flow through multiple channel bases. Rainwater is collected through collection holes, allowing it to flow along the water flow holes and be collected in the water tank, thus achieving automatic water replenishment of the water tank. When the channel base is short of water, the adjusting component opens the water supply hole and closes the water flow hole, allowing water in the water flow hole to flow into the interior of the channel base, thus replenishing the water-scarce channel base. Therefore, the environmentally friendly structure used to form a green isolation belt can achieve centralized collection of rainwater and centralized water supply for the green plants at the channel base, realizing the recycling of water resources and long-term water supply for the green plants. It also makes the green plants less dependent on rainy days. Through centralized collection of rainwater and centralized water supply for the green plants, the environmentally friendly structure can provide stable water supply to the green vegetation along the highway for a long time.

[0009] Optionally, the side wall of the channel base is provided with a detection hole for detecting water shortage in the channel base. One end of the detection hole is connected to the top of the channel base, and the other end is located on one side of the water flow hole. The adjustment component includes a convex lens fixedly disposed at the end of the detection hole away from the water flow hole, a baffle plate located at the end of the detection hole away from the convex lens and slidably inserted into the water flow hole, a driving part for driving the baffle plate to slide by means of the heat of the focal point of the convex lens and by the principle of thermal expansion and contraction, and a blocking plate hinged to the water supply hole. The detection hole communicates with the interior of the channel base through a detection water hole. The baffle plate is located on the side of the channel base near the tail end of the water supply hole and is used to close the water flow hole. The blocking plate is used to close the water supply hole. When the baffle plate closes the water flow hole, the blocking plate makes the water supply hole open. When the baffle plate makes the water flow hole open, the blocking plate closes the water supply hole.

[0010] By adopting the above technical solution, sunlight shines on the convex lens, which focuses the sunlight onto the drive unit. Driven by the heat at the focal point of the convex lens, the drive unit pushes the baffle plate to slide, causing the baffle plate to close the water flow hole. At the same time, the blocking plate opens the water supply hole, thus enabling timely water replenishment to the channel base when it is short of water, with the help of sunlight. When water is stored in the channel base, the water in the channel base flows into the detection hole from the detection water hole. The water in the detection hole changes the focal position of the convex lens and absorbs the heat of the light focused by the convex lens, making it difficult for the drive unit to obtain a heat source. The baffle plate slides in the opposite direction to open the water flow hole, and the blocking plate closes the water supply hole, thus making it easy to replenish water to the channel base when it is short of water and to automatically stop replenishing water after water is stored.

[0011] Optionally, the driving unit includes a heat-conducting plate fixedly disposed in the detection hole and located at one end of the detection hole near the water flow hole, and an elastic box fixedly connected to the heat-conducting plate and located on the side of the heat-conducting plate near the water flow hole. The focal point of the convex lens is located on the heat-conducting plate. The heat-conducting plate is made of a heat-conducting material, and the elastic box is filled with air.

[0012] By adopting the above technical solution, the heat-conducting plate absorbs the heat from the focal point of the convex lens and transfers the heat to the elastic box. The air inside the elastic box expands due to the heat, and the expanded air increases the volume of the elastic box. The elastic box pushes the baffle plate to slide into the water flow hole. When water is stored in the detection hole, the water absorbs the heat from the heat-conducting plate and cools the air inside the elastic box. The elastic box contracts and drives the baffle plate to slide out of the water flow hole, thereby making it easier for the baffle plate to close or open the water flow hole.

[0013] Optionally, a cooling rod is fixedly connected to the elastic box. The cooling rod passes through the channel base, with one end away from the elastic box entering the channel base. The cooling rod is also made of a thermally conductive material.

[0014] By adopting the above technical solution, when water is stored in the channel base, the water in the channel base can directly exchange heat with the air in the elastic box through the cooling rod, which makes it easier to cool the air in the elastic box.

[0015] Optionally, a pull rope is fixedly connected between the end of the blocking plate away from the hinge and the end of the baffle plate located inside the detection hole. The pull rope is slidably threaded through the channel base. A spring is fixedly provided between the blocking plate and the side wall of the water supply hole. The spring is used to drive the blocking plate to close the water supply hole.

[0016] By adopting the above technical solution, when the baffle slides into the water flow hole, the baffle pulls the pull rope to slide, the pull rope pulls the blocking plate to rotate, and the blocking plate causes the spring plate to accumulate elastic force, so that when the baffle closes the water flow hole, the blocking plate can open the water supply hole. When the baffle slides out of the water flow hole, under the action of the elastic force of the spring plate, the pull rope slides in the opposite direction, the spring plate causes the blocking plate to rotate, and the blocking plate closes the water supply hole. Thus, the baffle and the blocking plate can easily move synchronously under the action of the pull rope and the spring plate.

[0017] Optionally, a partition is fixedly installed inside the channel base, dividing the channel base into two chambers. The chamber on the side of the partition closer to the bottom of the channel base is a water storage chamber, and the chamber on the side of the partition away from the bottom of the channel base is a planting chamber. Green plants are planted in the planting chamber, and the water storage chamber is used to store water. The connection between the water detection hole and the channel base is located in the middle of the water storage chamber, and multiple capillary tubes are fixedly inserted through the partition.

[0018] By adopting the above technical solution, the channel base is divided into a planting chamber and a water storage chamber by a partition, which makes it easy to store water in the channel base. The green plants in the planting chamber can slowly and continuously absorb water through capillaries, reducing the natural evaporation of water in the channel base.

[0019] Optionally, the partition plate is provided with multiple water passage holes.

[0020] By adopting the above technical solution, the water passage holes on the partition can facilitate water exchange between the planting chamber and the water storage chamber. Thus, on rainy days, the water collected in the planting chamber can flow into the water storage chamber for storage, and on dry days, the water stored in the water storage chamber can be directly supplied to the planting chamber.

[0021] Optionally, an overflow hole is provided between the top of the channel base and the collection hole.

[0022] By adopting the above technical solution, when the water in the planting cavity is full, the water can flow from the overflow hole through the collection hole into the water flow hole, thus making it easier for the channel base to collect rainwater on rainy days.

[0023] Optionally, a filter screen is provided inside the collection hole, and the filter screen is inclined relative to the horizontal plane.

[0024] By adopting the above technical solution, the filter screen filters the water in the collection hole, making it difficult for impurities in the water to flow into the water flow hole, thus preventing the water flow hole from becoming clogged. Furthermore, because the filter screen is set at an angle relative to the horizontal plane, impurities are more likely to accumulate at the bottom of the filter screen, making the filter screen less prone to clogging.

[0025] Optionally, an intercepting net is provided at the connection between the collection hole and the top of the channel base. The intercepting net is fixedly connected to the filter screen, and both the intercepting net and the filter screen are slidably connected to the channel base.

[0026] By adopting the above technical solution, the interception net intercepts impurities in the rainwater entering the collection hole, making it less likely for impurities to accumulate at the filter screen. Furthermore, the interception net facilitates the filter screen to slide out of the collection hole, making the filter screen easy to clean.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By opening water flow holes, water supply holes, and collection holes, and by setting baffles and blocking plates, the environmental protection structure can achieve centralized collection of rainwater and centralized water supply to the channel base, thereby enabling long-term and stable water supply to the green vegetation along the highway.

[0029] 2. By setting up a convex lens, a heat-conducting plate, and an elastic box, the sliding of the baffle can be facilitated by utilizing natural energy, and the sliding of the baffle can be matched with weather conditions;

[0030] 3. By setting up interception nets and filter nets, impurities are not easily allowed to flow into the collection holes and water flow holes, making it less likely for the collection holes and water flow holes to become clogged. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0041] This application discloses an environmentally friendly structure for highways. (Refer to...) Figure 1 and Figure 2 An environmentally friendly highway structure includes multiple U-shaped channel bases 1 connected end to end. The channel bases 1 are used for planting greenery and have water flow holes 11, collection holes 12 connected to the water flow holes 11, and water supply holes 13 connecting the interior of the channel bases 1 to the water flow holes 11. Between two adjacent channel bases 1, the water flow holes 11 of one channel base 1 are connected to the water flow holes 11 of the other channel base 1. The water flow holes 11 of the channel bases 1 at the first end are connected to a water pump 2, and the water pump 2 is connected to a water tank 3. The water tank 3 is used to store water and is connected to the water flow holes 11 of the channel bases 1 at the second end through a pipeline. The channel bases 1 are equipped with adjustment components 4 for controlling the opening or closing of the water flow holes 11 and the water supply holes 13.

[0042] In use, the water pump 2 draws water from the water tank 3 into the water flow hole 11. The water flows back from the water flow hole 11 of the multiple channel bases 1 into the water tank 3. The collection hole 12 collects rainwater and allows the rainwater to flow back from the water flow hole 11 into the water tank 3, making it easy to collect rainwater in a concentrated manner. This makes the green plants in the channel base 1 less dependent on rainy days. When there is a shortage of water in the channel base 1, the regulating component 4 controls the water flow hole 11 to close and controls the water supply hole 13 to open, so that water can flow into the channel base 1 from the water supply hole 13. This makes it easy for the channel base 1 to supply water in a concentrated manner, and thus the channel base 1 can provide water to the green vegetation of the highway in a long-term and stable manner.

[0043] Reference Figure 2The channel base 1 is horizontally positioned and contains a rectangular plate 5. The plate is located in the center of the channel base 1 and is fixedly connected to both side walls of the channel base 1. The plate 5 divides the interior of the channel base 1 into two chambers: the chamber closer to the bottom of the channel base 1 is a water storage chamber, and the chamber further away from the bottom is a planting chamber. Plants are grown in the planting chamber, and the water storage chamber stores water replenished to the channel base 1.

[0044] The partition 5 has multiple circular water passage holes 52 arranged in a rectangular array, and the water passage holes 52 penetrate the thickness of the partition 5. Multiple circular capillary tubes 51 are fixedly inserted into the partition 5, arranged in a rectangular array and staggered from the water passage holes 52. The capillary tubes 51 are vertically arranged, with their top ends flush with the top surface of the partition 5, and their bottom ends located above the inner bottom surface of the channel base 1, with a gap between them and the inner bottom surface of the channel base 1.

[0045] Reference Figure 3 The collection hole 12 is rectangular and located on one of the side walls of the channel base 1. The top end of the collection hole 12 penetrates the top surface of the channel base 1, and the bottom end is connected to one side of the water flow hole 11 along its length. A rectangular overflow hole 15 is provided between the top of the collection hole 12 and the top of the interior of the channel base 1.

[0046] The top of the collection hole 12 is provided with an intercepting net 7 that is adapted to itself, and a filter net 6 is provided at the corresponding part of the bottom of the side wall of the channel base 1. The intercepting net 7 is horizontally set, and the filter net 6 is rectangular and inclined to the horizontal plane. The mesh surface of the filter net 6 is perpendicular to the extension direction of the collection hole 12 on the side wall of the channel base 1. The filter net 6 and the intercepting net 7 are fixedly connected by rods. Both the filter net 6 and the intercepting net 7 are slidably connected to the channel base 1, and the sliding direction is the extension direction of the collection hole 12 on the side wall of the channel base 1.

[0047] In use, during rainy weather, rainwater flows into the collection hole 12, and the interception net 7 intercepts impurities in the rainwater. The rainwater flows into the water flow hole 11 through the collection hole 12. When the channel base 1 is full of rainwater, the rainwater in the channel base 1 flows into the collection hole 12 through the overflow hole 15. The rainwater in the collection hole 12 flows into the water tank 3 along with the water flow hole 11. The filter net 6 filters the impurities in the rainwater. Thus, the rainwater is easily collected through the collection hole 12 and the overflow hole 15, making it easy for the water in the water tank 3 to be automatically replenished, and realizing the centralized collection of rainwater.

[0048] Reference Figure 2 and Figure 4The water supply hole 13 is rectangular and located at the center of the bottom surface of the channel base 1. A detection hole 14 is provided on the other side wall of the channel base 1. The detection hole 14 is located on the side of the channel base 1 near the tail end of the water supply hole 13. The detection hole 14 is circular, with one end penetrating through the top surface of the channel base 1, and the other end of the detection hole 14 located on the side of the water flow hole 11 away from the collection hole 12.

[0049] Reference Figure 4 and Figure 5 A rectangular water detection hole 141 is provided between the detection hole 14 and the water storage cavity, and the water detection hole 141 is located in the middle of the water storage cavity. The adjustment assembly 4 includes a convex lens 41, a baffle plate 42, a drive unit 43 and a blocking plate 44. The convex lens 41 is circular and coaxially arranged with the detection hole 14. The convex lens 41 is fixedly connected to the top of the detection hole 14.

[0050] Reference Figure 4 The baffle plate 42 is rectangular and located at the end of the detection hole 14 near the water flow hole 11. The baffle plate 42 is installed on the channel base 1 and inserted into the water flow hole 11. The baffle plate 42 is slidably connected to the channel base 1, and the sliding direction is perpendicular to the length direction of the water flow hole 11. The width of the baffle plate 42 is adapted to the dimension of the water flow hole 11 in the direction perpendicular to the bottom surface of the channel base 1. The baffle plate 42 is used to close the water flow hole 11.

[0051] The drive unit 43 includes a heat-conducting plate 431 and an elastic box 432. The heat-conducting plate 431 is circular and is adapted to the detection hole 14. The heat-conducting plate 431 is located at the position corresponding to the bottom of the side wall of the channel base 1 and is fixedly connected to the channel base 1. The heat-conducting plate 431 is vertically arranged and its center is located at the focal point of the convex lens 41. The heat-conducting plate 431 is made of a heat-conducting material, such as copper or aluminum.

[0052] The elastic box 432 is circular and has corrugated sidewalls. The elastic box 432 is located inside the detection hole 14 and between the baffle plate 42 and the heat-conducting plate 431. The two ends of the elastic box 432 along the axial direction are fixedly connected to the baffle plate 42 and the heat-conducting plate 431, respectively. The elastic box 432 is filled with air and is made of elastic rubber.

[0053] Reference Figure 4 and Figure 6 A cooling rod 45 is fixedly connected to the side wall of the elastic box 432. The cooling rod 45 is inserted into the interior of the elastic box 432. The cooling rod 45 is in the shape of a round rod and is fixedly inserted into the channel base 1. The end of the cooling rod 45 away from the elastic box 432 is inserted into the interior of the channel base 1. The cooling rod 45 is also made of heat-conducting material.

[0054] Reference Figure 4 and Figure 7The blocking plate 44 is rectangular and hinged at the connection between the water supply hole 13 and the water flow hole 11. The blocking plate 44 is adapted to the water supply hole 13. The hinge of the blocking plate 44 is located on the side of itself closer to the detection hole 14. The blocking plate 44 is used to seal the water supply hole 13.

[0055] Reference Figure 6 and Figure 7 A pull rope 46 is fixedly connected to the side of the top surface of the blockage plate 44 away from the hinge. The pull rope 46 passes through the channel base 1 and is slidably connected to the channel base 1. The end of the pull rope 46 away from the blockage plate 44 is fixedly connected to the end of the baffle plate 42 near the elastic box 432. The pull rope 46 is in a tensioned state. A spring piece 47 is provided on the side of the top surface of the blockage plate 44 near the hinge. The spring piece 47 is rectangular and bent at 90°. One bent side of the spring piece 47 is fixedly connected to the top surface of the blockage plate 44, and the other bent side is fixedly connected to the side wall of the water supply hole 13. The spring piece 47 is used to drive the blockage plate 44 to close the water supply hole 13.

[0056] When in use, when the channel base 1 is short of water, sunlight shines on the convex lens 41, which focuses the sunlight onto the heat-conducting plate 431. The heat-conducting plate 431 heats up and transfers the heat to the elastic box 432. The air inside the elastic box 432 expands due to the heat, and the expanded air pushes the elastic box 432 to extend. The elastic box 432 pushes the baffle plate 42 to slide into the water flow hole 11 and closes the water flow hole 11. The baffle plate 42 pulls the pull rope 46 to slide into the detection hole 14. The pull rope 46 pulls the blocking plate 44 to rotate, and the blocking plate 44 opens the water supply hole 13 and allows the spring piece 47 to accumulate elasticity. The water in the water flow hole 11 flows into the water storage chamber along the water supply hole 13, and the water level in the water storage chamber gradually rises. The water in the water storage chamber flows into the planting chamber through the water passage hole 52, thus realizing the replenishment of water for the green plants.

[0057] Water in the water storage chamber flows into the detection hole 14 from the detection water hole 141. The water in the detection hole 14 cools the heat conduction plate 431 and changes the focal position of the convex lens 41. The heat conduction plate 431 cools the air in the elastic box 432. The air in the elastic box 432 also exchanges heat directly with the water in the channel base 1 through the cooling rod 45, cooling the air in the elastic box 432. Under the action of negative pressure, the elastic box 432 gradually contracts. The elastic box 432 pulls the baffle plate 42 to slide out of the water flow hole 11, making the water flow hole 11 open. The spring plate 47 drives the blocking plate 44 to rotate in the opposite direction through elastic force. The blocking plate 44 causes the pull rope 46 to slide in the opposite direction. The blocking plate 44 closes the water supply hole 13, thus making it easy for the water in the channel base 1 to be automatically replenished.

[0058] The implementation principle of the environmental protection structure for highways in this application embodiment is as follows: When in use, the water pump 2 draws water from the water tank 3 into the water flow hole 11, and the water flows back into the water tank 3 along the water flow hole 11. On rainy days, rainwater flows into the water flow hole 11 from the collection hole 12 and the overflow hole 15, and the rainwater flows back into the water tank 3 along with the water in the water flow hole 11, realizing the centralized collection of rainwater, reducing dependence on rainy days, and realizing automatic water replenishment of the water tank 3.

[0059] When the channel base 1 is short of water, sunlight shines on the convex lens 41, which focuses the sunlight onto the heat-conducting plate 431. The heat-conducting plate 431 absorbs heat and causes the air in the elastic box 432 to expand. The expanded air pushes the baffle plate 42 through the elastic box 432 into the water flow hole 11. The baffle plate 42 closes the water flow hole 11, and the pull rope 46 rotates the blocking plate 44, which opens the water supply hole 13, allowing the water in the water flow hole 11 to replenish the channel base 1. This achieves centralized water supply to the channel base 1. Thus, through the centralized collection of rainwater and the centralized water supply to the channel base 1, the environmentally friendly structure can provide stable water supply to the green vegetation along the highway for a long period of time.

[0060] 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.
