Description

Technical Field

[0001] This application relates to the technical field of green belts, and in particular to an environmentally friendly green belt based on expressways. Background Art

[0002] Green belts have the functions of eliminating visual fatigue, purifying the environment, reducing traffic accidents, etc., and the green belts of expressways are particularly important.

[0003] The maintenance of green belts includes watering and fertilizing. Plants should not be over-watered, otherwise they are prone to waterlogging and death; when fertilizing plants, the fertilizer needs to be diluted with water, otherwise it is easy to cause seedling burning and the death of the green belt plants.

[0004] Currently, the watering and fertilizing of green belts are both carried out by operators driving operation tool vehicles. However, due to the high speed of vehicles on expressways, when operators carry out the maintenance of the median green belt on expressways, it is easy to cause traffic accidents, which causes difficulties in the maintenance of the green belts on expressways. Summary of the Invention

[0005] In order to facilitate the maintenance of the green belts on expressways, this application provides an environmentally friendly green belt based on expressways.

[0006] An environmentally friendly green belt based on expressways provided by this application adopts the following technical solutions:

[0008] By adopting the above technical solutions, when maintaining the green belts on expressways, the watering component automatically waters the soil layer, and at the same time, the fertilizing component automatically fertilizes the soil layer. There is no need for operators to carry out maintenance, which facilitates the maintenance of the green belts on expressways.

[0009] Optionally, the watering component includes a water storage tank, a water delivery pipe, a water collection component and a detection component; the water storage tank is arranged at the bottom of the soil layer; one end of the water delivery pipe is communicated with the water storage tank, and the other end of the water delivery pipe is located inside the soil layer; a water pump is installed on the water delivery pipe; the water collection component is arranged on the curb stones and is used for collecting rainwater into the water storage tank; the detection component is arranged on the curb stones and is used for detecting the humidity of the soil layer and controlling the working state of the water pump.

[0010] By adopting the above technical solution, during rainy days, rainwater is collected into the water storage tank through the water collection component, and then the humidity of the soil layer is monitored in real time by the detection component. When the humidity of the soil layer is lower than the preset value, the water pump is controlled to start. Under the action of the water pump, the water in the water storage tank is transported into the soil layer through the water delivery pipe. The humidity of the soil layer is monitored in real time by the detection component, and the soil layer is automatically watered, so that when the soil moisture is insufficient, the soil layer is watered, realizing automatic watering of the soil layer.

[0011] Optionally, an installation cavity is provided inside the curbstone; the fertilization component includes a fertilizer storage tank, a fertilizer delivery pipe, a control component, and an adjustment component; the fertilizer storage tank is arranged in the installation cavity and is used for storing fertilizers; one end of the fertilizer delivery pipe is communicated with the bottom of the fertilizer storage tank, and the other end is communicated with the water delivery pipe. The connection between the fertilizer delivery pipe and the water delivery pipe is located at the bottom of the fertilizer storage tank; the control component is arranged inside the installation cavity and is used for controlling the connection state at both ends of the fertilizer delivery pipe; the adjustment component is arranged on the water storage tank and is used for adjusting the flow rate of the fertilizer in the fertilizer delivery pipe.

[0012] By adopting the above technical solution, the connection state at both ends of the fertilizer delivery pipe is controlled by the control component, so that fertilizers enter the water delivery pipe through the fertilizer delivery pipe while watering, and are mixed into the water, realizing fertilization while watering the soil layer; the flow rate of the fertilizer in the fertilizer delivery pipe is adjusted by the adjustment component, so as to adjust the fertilization amount for the soil layer each time according to the watering frequency, ensuring that the amount of fertilizer received by the soil layer is the same within a certain period of time, and realizing automatic fertilization of the highway green belt.

[0013] Optionally, the control component includes a first telescopic rod, an overflow valve, and a spring; the first telescopic rod is installed on the water delivery pipe, the movable end of the first telescopic rod is inserted into the fertilizer delivery pipe, and the fixed end of the first telescopic rod is fixedly connected to the fertilizer delivery pipe. The movable end of the first telescopic rod divides the fixed end of the first telescopic rod into a first rod chamber and a first rodless chamber; the water delivery pipe is communicated with the first rod chamber; an overflow valve is installed on the water delivery pipe, and the overflow valve is located on the side of the first telescopic rod close to the soil layer; the spring is located in the first rodless chamber, and both ends of the spring are fixedly connected to the movable end and the fixed end of the first telescopic rod respectively.

[0014] By adopting the above technical solution, when watering the soil layer, the water in the water storage tank flows into the first rod chamber along the water delivery pipe under the action of the water pump. The water entering the first rod chamber first squeezes the movable end of the first telescopic rod under the action of the overflow valve. The movable end of the first telescopic rod contracts, and the two ends of the fertilizer delivery pipe are in a communicating state. At this time, the spring is squeezed and contracts. When the first telescopic rod contracts to the maximum contraction amount, as the water flows in, the water continues to flow through the overflow valve to water the soil layer; after the water pump stops working, the first telescopic rod extends and resets under the action of the spring, and the two ends of the fertilizer delivery pipe are in an isolated state, realizing the control of the communicating state of the two ends of the fertilizer delivery pipe, so that when watering, the two ends of the fertilizer delivery pipe are communicated, and when watering stops, the two ends of the fertilizer delivery pipe are isolated.

[0015] Optionally, the adjusting component includes a floating ball and a second telescopic rod; the floating ball is arranged in the water storage tank; the second telescopic rod is arranged vertically, the fixed end of the second telescopic rod is fixedly connected to the top of the water storage tank, and the movable end of the second telescopic rod is fixedly connected to the floating ball; the movable end of the second telescopic rod divides the fixed end of the second telescopic rod into a second rod chamber and a second rodless chamber; the second rod chamber is always located at the bottom of the first rodless chamber, the second rod chamber and the first rodless chamber are communicated through a pipeline, and liquids are preset in the second rod chamber, the first rodless chamber and the pipeline between the two.

[0016] By adopting the above technical solution, the floating ball is located above the water in the water storage tank. When the rainfall is relatively large and the rainfall is frequent, at this time, the watering frequency of the soil layer is relatively low, the water level in the water storage tank is high, and the height of the floating ball is high, then the more the second telescopic rod contracts, the larger the volume of the second rod chamber. Under the action of gravity, the liquid in the first rodless chamber enters the second rod chamber through the pipeline, and the amount of liquid in the first rodless chamber decreases, then the more the first telescopic rod can contract. When the water enters the first rod chamber and squeezes the movable end of the first telescopic rod, the greater the contraction amount of the first telescopic rod, the greater the flow rate in the fertilizer delivery pipe.

[0017] When the rainfall is relatively small, at this time, the watering frequency of the soil layer is relatively high, the water level in the water storage tank is low, and the height of the floating ball is low, then the smaller the contraction amount of the second telescopic rod, the smaller the volume of the second rod chamber. Then, under the action of gravity, the liquid in the second rod chamber is squeezed and enters the first rodless chamber through the pipeline, and the amount of liquid in the first rodless chamber increases, then the smaller the amount that the first telescopic rod can contract. When the water enters the first rod chamber and squeezes the movable end of the first telescopic rod, the smaller the contraction amount of the first telescopic rod, the smaller the flow rate in the fertilizer delivery pipe. It realizes the adjustment of the fertilization amount for the soil layer each time according to the watering frequency, so that the higher the watering frequency, the less the fertilization amount each time, and the lower the watering frequency, the more the fertilizer amount each time, ensuring that the fertilization amount for the soil layer is certain within a certain period of time.

[0018] Optionally, a water filtration layer is provided at the bottom of the soil layer; the water storage tank has an open top structure; water collection grooves are formed on both sides of the curb; the water collection component includes a water collection pipe and a filter plate; one end of the water collection pipe is communicated with the water collection groove, and the other end is communicated with the water storage tank; the filter plate is fixedly arranged at the notch of the water collection groove.

[0019] By adopting the above technical solution, during rain, the rainwater on the road surface and part of the rainwater on the soil layer enter the water storage tank through the water collection groove and the water collection pipe for storage, and part of the rainwater that penetrates into the soil layer passes through the water filtration layer and enters the water storage tank for storage. The stored rainwater is used to water the plants, achieving the full utilization of rainwater resources.

[0020] Optionally, the detection component includes a humidity sensor and a controller; the humidity sensor is arranged in the soil layer and is used to detect the humidity information in the soil layer and convert it into a humidity signal; the controller is arranged on the curb, and the controller is electrically connected to both the humidity sensor and the water pump. The controller is used to receive the humidity signal transmitted by the humidity sensor and control the working state of the water pump.

[0021] By adopting the above technical solution, the humidity sensor is used to monitor the soil humidity in real time, so that when the soil layer lacks water, the soil layer can be watered in time without the need for staff to check, which facilitates the maintenance of the green belt of the highway.

[0022] Optionally, a power supply component is further included, and the power supply component includes a solar panel and a storage battery; the solar panel is fixedly arranged on the top of the soil layer, the storage battery is arranged on the curb, and the solar panel, the storage battery and the controller are all electrically connected.

[0024] Optionally, a spiral rod is arranged in the water delivery pipe, the spiral rod is rotationally connected to the water delivery pipe, and the spiral rod is located on the side close to the soil layer at the connection of the fertilizer delivery pipe and the water delivery pipe.

[0025] By adopting the above technical solution, the fertilizer entering the water delivery pipe flows to the spiral rod under the drive of water, and the spiral rod rotates in the water delivery pipe under the drive of the water flow, so that the water and the fertilizer are fully mixed evenly, ensuring that the fertilizer can be evenly spread in the soil layer under the drive of water and guaranteeing the fertilization effect on the soil layer.

[0027] 1. By setting up a watering component and a fertilizing component, when maintaining the green belt of the highway, the watering component automatically waters the soil layer, and at the same time, the fertilizing component automatically fertilizes the soil layer. There is no need for operators to carry out maintenance, which facilitates the maintenance of the green belt of the highway;

[0028] 2. By setting up a control component, when watering the soil layer, both ends of the fertilizer delivery pipe are in a connected state. When watering the soil layer stops, both ends of the fertilizer delivery pipe are in an isolated state, so that fertilization is carried out while watering the soil layer, and the fertilizer and water are fully mixed. On the one hand, it prevents plant seedling burning, and on the other hand, it evenly spreads the fertilizer in the soil layer, ensuring the maintenance quality of the green belt of the highway;

[0029] 3. By setting up an adjustment component, it is realized to adjust the amount of fertilizer applied to the soil layer each time according to the watering frequency of the soil layer, so that the higher the watering frequency, the less the amount of fertilizer applied each time, and the lower the watering frequency, the more the amount of fertilizer applied each time, ensuring that the amount of fertilizer applied to the soil layer is constant within a certain period of time.

[0041] The following further elaborates on this application Figures 1-5 in conjunction with the appended drawings.

[0042] An embodiment of this application discloses an environmentally friendly green belt based on a highway. Referring to Figure 1 , an environmentally friendly green belt based on a highway includes a soil layer 1, a watering component 2, and a fertilizing component 3. The soil layer 1 is horizontally arranged and is used for planting greening plants. Curbstones 4 are arranged on both sides of the soil layer 1. The curbstones 4 are vertically arranged and are fixedly connected to the road surface. An installation cavity 41 is formed inside the curbstone 4. The watering component 2 is arranged on the curbstone 4 and is used for automatically watering the soil layer 1. The fertilizing component 3 is arranged on the curbstone 4 and is used for automatically fertilizing the soil layer 1.

[0043] When maintaining the highway green belt, the soil layer 1 is automatically watered through the watering component 2. At the same time of watering, the soil layer 1 is automatically fertilized through the fertilizing component 3 to complete the maintenance of the highway green belt.

[0044] Referring to Figure 1 , water collecting troughs 42 are formed on both sides of the curbstone 4. The water collecting troughs 42 are used for collecting rainwater on the road surface and the surface of the soil layer 1. A water filtering layer 11 is arranged at the bottom of the soil layer 1. The watering component 2 includes a water storage tank 21, a water collecting component 23, a water delivery pipe 22, and a detection component 24. The water storage tank 21 is arranged at the bottom of the water filtering layer 11. The water storage tank 21 has an open top structure. The water collecting component 23 includes a water collecting pipe 231 and a filtering plate 232. Both water collecting troughs 42 are communicated with the water storage tank 21 through the water collecting pipe 231. The side wall of the water collecting trough 42 communicated with the water collecting pipe 231 is inclined downward along the direction close to the water collecting pipe 231. The filtering plate 232 is fixedly arranged at the notch of the water collecting trough 42.

[0045] In areas with less rainfall, the water storage tank 21 can be supplied with water through an external water source.

[0046] When it rains, when rainwater drips onto the road surface and the soil layer 1, the rainwater on the road surface enters the water storage tank 21 through the water collection tank 42 and the water collection pipe 231 and is stored. Part of the rainwater on the soil layer 1 enters the water storage tank 21 through the water collection tank 42 and the water collection pipe 231, and the other part penetrates into the interior of the soil layer 1. The rainwater that penetrates into the interior of the soil layer 1 is partially absorbed by the plant roots, and the excess water enters the water storage tank 21 through the water filtration layer 11 and is stored.

[0047] Referring to Figure 2 and Figure 3 , one end of the water delivery pipe 22 is connected to the bottom of the water storage tank 21, and the other end of the water delivery pipe 22 is located inside the soil layer 1. The part of the water delivery pipe 22 located inside the soil layer 1 is arranged in an S shape along the length direction of the water storage tank 21. Water seepage holes are formed in the part of the water delivery pipe 22 located inside the soil layer 1. A water pump 221 is installed on the water delivery pipe 22.

[0048] The detection component 24 includes a humidity sensor 241 and a controller 242. The humidity sensor 241 is located inside the soil layer 1 and is fixedly connected to the curbstone 4. The humidity sensor 241 is used to detect the humidity information in the soil layer 1 and convert it into a humidity signal. The controller 242 is arranged in the installation cavity 41, the controller 242 is fixedly connected to the curbstone 4, the controller 242 is electrically connected to both the humidity sensor 241 and the water pump 221, and the controller 242 is used to receive the humidity signal transmitted by the humidity sensor 241 and control the working state of the water pump 221.

[0049] Referring to Figure 1 , a power supply component 5 is arranged on the soil layer 1. The power supply component 5 includes a solar panel 51 and a storage battery 52. The solar panel 51 is fixedly arranged on the top of the soil layer 1 through a support rod. The solar panel 51 is used to convert solar energy into electrical energy. The storage battery 52 is arranged on the curbstone 4. The solar panel 51, the storage battery 52 and the controller 242 are all electrically connected. The storage battery 52 is used to store the electrical energy converted by the solar panel 51 and supply electrical energy to the controller 242, the humidity sensor 241 and the water pump 221.

[0050] After the solar panel 51 receives sunlight, it converts solar energy into electrical energy and stores it in the storage battery 52. The humidity sensor 241 is always in a working state after receiving electrical energy. The humidity sensor 241 detects the humidity information in the soil layer 1. When the humidity value in the soil layer 1 is lower than the preset value, the controller 242 controls the water pump 221 to start. The water in the water storage tank 21 flows in an S shape along the water delivery pipe 22 under the action of the water pump 221. During the flowing process, it uniformly seeps into the soil layer 1 through the water seepage holes. The water pump 221 stops working after a preset time, completing the watering of the highway green belt.

[0051] Referring to Figure 4, the fertilizing assembly 3 includes a fertilizer storage tank 31, a fertilizer delivery pipe 32, a control component 33, and an adjusting component 34. The fertilizer storage tank 31 is arranged in the installation cavity 41, and the fertilizer storage tank 31 is fixedly connected to the curbstone 4. The fertilizer storage tank 31 is used for storing fertilizers. The fertilizer delivery pipe 32 is arranged obliquely. The top end of the fertilizer delivery pipe 32 is communicated with the bottom of the fertilizer storage tank 31, and the bottom end of the fertilizer delivery pipe 32 is communicated with the water delivery pipe 22. The bottom of the fertilizer storage tank 31 is arranged to slope downward along the direction close to the connection with the fertilizer delivery pipe 32 itself.

[0052] Referring to Figure 4 and Figure 5 , the control component 33 includes a first telescopic rod 331, an overflow valve 332, and a spring 333. The first telescopic rod 331 is installed on the water delivery pipe 22. The movable end of the first telescopic rod 331 is inserted into the fertilizer delivery pipe 32. When the end face of the movable end of the first telescopic rod 331 away from the fixed end of the first telescopic rod 331 abuts against the wall of the fertilizer delivery pipe 32, both ends of the fertilizer delivery pipe 32 are in an isolated state. The fixed end of the first telescopic rod 331 is fixedly connected to the fertilizer delivery pipe 32, and the connection part is located at the top of the connection between the fertilizer delivery pipe 32 and the water delivery pipe 22. The movable end of the first telescopic rod 331 divides the fixed end of the first telescopic rod 331 into a first rod chamber 3311 and a first rodless chamber 3312. The first rod chamber 3311 is located between the first rodless chamber 3312 and the fertilizer delivery pipe 32.

[0053] The water delivery pipe 22 is communicated with the first rod chamber 3311, and the communication part is located on the side of the connection between the water delivery pipe 22 and the fertilizer delivery pipe 32 away from the soil layer 1. An overflow valve 332 is installed on the water delivery pipe 22. The overflow valve 332 is located between the communication part of the first rod chamber 3311 and the water delivery pipe 22 and the communication part of the water delivery pipe 22 and the fertilizer delivery pipe 32. The spring 333 is located in the first rodless chamber 3312. The length direction of the spring 333 is the same as the length direction of the first telescopic rod 331, and both ends of the spring 333 are fixedly connected to the movable end and the fixed end of the first telescopic rod 331 respectively. The starting pressure of the overflow valve 332 is greater than the elastic force of the spring 333.

[0054] A spiral rod 222 is arranged in the water delivery pipe 22. The spiral rod 222 is located on the side of the connection between the fertilizer delivery pipe 32 and the water delivery pipe 22 close to the soil layer 1. The spiral rod 222 is rotatably connected to the water delivery pipe 22, and the rotation axis is the same as the length direction of the water delivery pipe 22.

[0055] When the water in the water storage tank 21 flows along the water delivery pipe 22 under the action of the water pump 221, the water enters the first rod chamber 3311. Since the starting pressure of the overflow valve 332 is greater than the elastic force of the spring 333, the water first squeezes the movable end of the first telescopic rod 331, causing the first telescopic rod 331 to contract. The two ends of the fertilizer delivery pipe 32 are in a communicating state, and the fertilizer in the fertilizer storage tank 31 flows into the water delivery pipe 22 through the fertilizer delivery pipe 32 under the action of its own gravity. At the same time, when the water squeezes the first telescopic rod 331 to the maximum contraction amount, the volume of the first rod chamber 3311 remains unchanged. As the water flows in, the pressure of the water in the first rod chamber 3311 gradually becomes greater than the starting pressure of the overflow valve 332, so the water flows out of the first rod chamber 3311 through the overflow valve 332 and continues to flow along the water delivery pipe 22. When the water meets the fertilizer entering the water delivery pipe 22, it drives the fertilizer to flow to the screw rod 222. Under the action of the water flow, the screw rod 222 rotates in the water delivery pipe 22. The water and the fertilizer are mixed evenly under the action of the rotating screw rod 222, and the fertilizer-water mixture passing through the screw rod 222 continues to flow to the soil layer 1 and uniformly penetrates into the interior of the soil layer 1 through the water seepage holes. After the water pump 221 stops working, the first telescopic rod 331 extends and resets under the action of the spring 333, and the two ends of the fertilizer delivery pipe 32 are in an isolated state, completing the watering and fertilizing of the highway green belt.

[0056] Referring to Figure 4 and Figure 5 , the adjusting member 34 includes a floating ball 341 and a second telescopic rod 342. The floating ball 341 is arranged in the water storage tank 21, and the height of the floating ball 341 changes with the height of the water level in the water storage tank 21. The buoyancy force received by the floating ball 341 is greater than the starting pressure of the overflow valve 332. The second telescopic rod 342 is vertically arranged inside the water storage tank 21. The fixed end of the second telescopic rod 342 is fixedly connected to the top of the water storage tank 21, and the movable end of the second telescopic rod 342 is fixedly connected to the floating ball 341. The movable end of the second telescopic rod 342 divides the fixed end of the second telescopic rod 342 into a second rod chamber 3421 and a second rodless chamber 3422. The second rod chamber 3421 is located below the second rodless chamber 3422, the second rod chamber 3421 is located below the first rodless chamber 3312, the second rod chamber 3421 and the first rodless chamber 3312 are communicated through a pipeline, and water is preset in the second rod chamber 3421, the first rodless chamber 3312 and the pipeline between the two.

[0057] After the rain, there is more rainwater stored in the water storage tank 21. The liquid level in the water storage tank 21 is relatively high, the height of the floating ball 341 is relatively high, the second telescopic rod 342 contracts under the drive of the floating ball 341, the volume of the second rodless cavity 3421 increases, and a part of the water in the first rodless cavity 3312 enters the second rodless cavity 3421 through the pipeline under the action of gravity. The amount of water in the first rodless cavity 3312 decreases, and the retractable length of the first telescopic rod 331 increases. The longer the first telescopic rod 331 contracts under the action of water, the greater the flow rate in the fertilizer delivery pipe 32.

[0058] When the rainfall is less, the water level in the water storage tank 21 gradually decreases during the watering process, and the height of the floating ball 341 also decreases accordingly. Under the action of gravity, the water in the second rodless cavity 3421 is squeezed into the first rodless cavity 3312 through the pipeline. The amount of water in the first rodless cavity 3312 increases, and the retractable length of the first telescopic rod 331 decreases. The smaller the first telescopic rod 331 contracts under the action of water, the smaller the flow rate in the fertilizer delivery pipe 32.

[0059] When the rainfall is large and frequent, since the humidity of the soil layer 1 is relatively high, watering is not carried out for a period of time. Since fertilization is synchronized with watering, fertilization is not carried out either. Until the water in the soil volatilizes after a period of time, the humidity sensor 241 detects that the humidity of the soil layer 1 has decreased, and the controller 242 controls watering of the soil layer 1. At this time, since the soil layer 1 has not been fertilized for a period of time, the fertilization amount is increased by adjusting the component to supplement nutrients to the soil layer 1.

[0060] When the rainfall is less and there is no rainfall for a long time, since the humidity of the soil layer 1 is relatively low, the soil layer 1 needs to be watered frequently. Since fertilization is synchronized with watering, fertilization is also relatively frequent. In order to ensure that the fertilization amount for the soil layer 1 is the same within the same time, the amount of each fertilization is adjusted by the adjusting component to decrease.

[0061] The implementation principle of an environmentally friendly green belt based on a highway in an embodiment of the present application is as follows:

[0062] During use, the power supply component 5 converts solar energy into electrical energy and stores it in the storage battery 52. During rainy days, the water droplets falling on the road surface and the soil layer 1 are collected by the water collection component 23 and stored in the water storage tank 21. The humidity sensor 241 detects the humidity information in the soil layer 1. When the humidity value in the soil layer 1 is lower than the preset value, the controller 242 controls the watering component 2 to water the soil layer 1, completing the automatic watering of the highway green belt.

[0063] While watering the soil layer 1, the fertilizer in the fertilizer storage tank 31 is controlled by the control component 33 to be dissolved in water, and fertilization is carried out while watering. The flow rate of the fertilizer in the fertilizer delivery pipe 32 is adjusted by the adjustment component, so as to adjust the amount of fertilizer applied to the soil layer 1 each time, ensuring that the amount of fertilizer applied to the soil layer 1 is the same within the same time, and completing the automatic fertilization of the highway green belt.

[0064] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
