Description

A desert irrigation-free greening device and its usage method Technical Field

[0001] This invention relates to the field of ecological environment, and in particular to a desert irrigation-free greening device and its usage method. Background Technology

[0002] Existing desert afforestation devices are not convenient for collecting, storing, and utilizing natural water during use. This easily leads to the following drawbacks:

[0003] Low plant survival rates: In arid and semi-arid regions, water resources are a key factor limiting vegetation growth. The lack of effective water harvesting and storage mechanisms means that plants may not be able to obtain enough water to sustain life, leading to reduced survival rates.

[0004] Increased irrigation costs: Failure to fully utilize natural rainfall and air humidity means that additional water sources are needed for irrigation, increasing the economic costs and resource consumption of greening projects.

[0005] Low efficiency of ecological restoration: The purpose of desert greening is to improve the ecological environment, but if the greening device cannot effectively utilize limited water resources, it will slow down the restoration speed of the ecosystem and greatly reduce the effectiveness of desertification control.

[0006] Increased maintenance difficulty: If the design of the greening device itself is not conducive to the collection and retention of water, then in practical applications, more maintenance work will be required to ensure that the plants can get the necessary water. This not only increases the labor intensity, but may also affect the greening effect due to improper maintenance.

[0007] Poor environmental adaptability: A good desert afforestation plan should have a certain degree of self-regulation to cope with harsh natural conditions. If the device cannot effectively utilize natural water sources, it indicates poor environmental adaptability and difficulty in achieving long-term stable afforestation results.

[0045] In this embodiment, rainwater and water vapor in the air are collected by the water collection mechanism 2, and then filtered and stored, so that plants can be effectively irrigated even in arid desert environments where water resources are scarce. This design is suitable for arid regions and reduces dependence on external water sources.

[0046] The bottom surface of the planting box 1 is provided with a first mounting hole for the water collection mechanism 2 to pass through. A partition cylinder 11 is provided above the first mounting hole. A second mounting hole matching the structure of the partition cylinder 11 is provided on the support component. The water collection mechanism 2 passes through the partition cylinder 11 and the first mounting hole and is connected to the water storage container.

[0047] In this embodiment, the supporting component is a supporting plate 6. The supporting plate 6 is provided with multiple through holes for the roots of the plants to pass through. The supporting plate 6 is sleeved on the outside of the partition cylinder 11 through the second mounting hole, and the periphery of the supporting plate 6 is fixed to the inner wall of the planting box 1. The supporting plate 6 is used to support the soil 8 and prevent the soil 8 from falling off.

[0048] In this embodiment, the soil moisture sensor 10 is fixedly installed on the inner wall of the planting box 1, and the detection end of the soil moisture sensor 10 extends into the soil 8 to detect its moisture.

[0049] As shown in Figure 5, the water storage container includes a water storage tank 3 and a shell 4 disposed on the upper part of the water storage tank 3. The water storage tank 3 is provided with a third mounting hole 12 for installing the water collection mechanism 2. The top of the shell 4 is connected to the bottom of the planting box 1. The water pumping and conveying mechanism is disposed in the shell 4 and extends into the water storage tank 3. The water pumping and conveying mechanism can pass through the bottom of the planting box 1 to supply water to the liquid supply chamber 7.

[0050] In this embodiment, two water collection mechanisms 2 are provided. Two first mounting holes are provided on the bottom surface of the planting box 1, and a partition cylinder 11 is provided above each first mounting hole. The two water collection mechanisms 2 are located on both sides inside the planting box 1. A third mounting hole 12 is provided on both sides of the upper part of the water storage tank 3. The shell 4 is located at the center of the upper part of the water storage tank 3, and the two water collection mechanisms 2 are located on both sides of the shell 4.

[0051] In this embodiment, the water storage tank 3 is an insulated water storage tank, thereby reducing the evaporation of water in the water storage tank 3 due to high external temperatures.

[0052] The water pumping and conveying mechanism includes a pumping pipe 14, a water pump 13, and a water nozzle 15. The water nozzle 15 is disposed on the bottom surface of the planting box 1 and communicates with the liquid supply chamber 7. The water pump 13 is disposed in the housing 4. The water outlet of the water pump 13 is connected to the water nozzle 15, and the water inlet of the water pump 13 is connected to one end of the pumping pipe 14. The other end of the pumping pipe 14 extends into the water storage tank 3. The water pump 13 is connected to the controller 16. In this embodiment, the controller 16 is disposed in the housing 4.

[0053] In this embodiment, a soil moisture sensor 10 is used to monitor the moisture of the soil 8, and the water pump 13 is intelligently controlled by the controller 16 to ensure that water is supplied to the plants only when necessary, so that the plants receive an appropriate amount of water. This achieves automated and precise water resource management and avoids water waste.

[0054] A cover layer 9 is provided on the upper part of the soil 8, as shown in Figure 6. The cover layer 9 includes a perforated membrane 901, a straw layer 902 and a gravel layer 903 arranged sequentially from bottom to top.

[0055] In this embodiment, the covering layer 9 not only prevents rapid evaporation of water, but also improves the air permeability and moisture retention of the soil 8, which is beneficial for plant root respiration and nutrient absorption.

[0056] In this embodiment, the top of the dividing cylinder 11 is flush with the top of the planting box 1. Soil 8 is filled between the planting box 1 and the dividing cylinder 11, and the soil 8 is flush with the top of the planting box 1. The covering layer 9 is laid on the surface of the planting box 1 and the dividing cylinder 11, and is located above the soil 8.

[0057] In this embodiment, the collection pipe 203 is located inside the cover layer 9 and the partition cylinder 11. The upper part of the filter box 204 is located inside the partition cylinder 11, and the lower part extends through the first mounting hole to the outside and is installed at the third mounting hole 12 of the water storage tank 3. The outlet end of the solenoid valve 209 extends into the inner cavity of the water storage tank 3. Specifically, the filter box 204 is in contact with the inner wall of the partition cylinder 11 and the first mounting hole.

[0058] In this embodiment, soil 8 is a water-retaining soil. Specifically, the water-retaining soil includes humus and a high-molecular-weight water-retaining agent, which enhances the water retention capacity of soil 8 and helps maintain the water required for plant growth in a water-scarce environment.

[0059] A windproof barrier 5 is fixedly fitted on the upper part of the planting box 1, as shown in Figure 7. The windproof barrier 5 includes a first mounting ring 501, a second mounting ring 502, multiple connecting plates 503, and multiple mesh fabrics 504. The first mounting ring 501 is fixedly fitted on the upper part of the planting box 1. The second mounting ring 502 is located above the first mounting ring 501. The second mounting ring 502 is connected to the first mounting ring 501 through multiple connecting plates 503 arranged at intervals. A mesh fabric 504 is connected between any two adjacent connecting plates 503. The upper and lower ends of each mesh fabric 504 are respectively connected to the second mounting ring 502 and the first mounting ring 501.

[0060] In this embodiment, the windproof barrier 5 can effectively reduce the impact of wind and sand on the plants in the planting box 1, providing a more stable growth environment and helping to improve the survival rate and growth rate of the plants.

[0061] In this specific embodiment, the planting box 1 is a rectangular box with curved corners. Four connecting plates 503 are provided in the windbreak barrier 5. Each connecting plate 503 is a curved plate, and each curved plate is positioned at the upper part of one corner of the rectangular box. The first mounting ring 501, the second mounting ring 502, and the four curved plates form the frame of the windbreak barrier 5. A mesh fabric 504 is provided between any two adjacent curved plates, meaning that a mesh fabric 504 is provided on the front, back, left, and right sides of the upper part of the planting box 1.

[0062] This embodiment also provides a method for using the desert irrigation-free greening device 100, including the following steps:

[0063] Step 1: Prepare the planting box 1. First, ensure that the water collection mechanism 2, water storage container, windbreak 5, and support components are installed. Fill the planting box 1 with soil 8, and lay a covering layer 9 on top of the planting box 1. Plant the selected plants in the soil 8, allowing the plant roots to penetrate through the holes in the support components into the liquid supply chamber 7 for direct water absorption. Bury the water storage container and planting box 1 in the selected area of ​​the desert. The plants used in this embodiment are drought-resistant plants.

[0064] Step 2: Collect water from nature through water collection mechanism 2 and transport the water to a storage container.

[0065] Specifically, rainwater is collected by the collection bucket 201, and water vapor in the air is collected by the condensation collection plate 202. The condensation collection plate 202 is designed as a downward-sloping triangle, and the upper and lower parts of its surface have a hydrophilic layer and a hydrophobic layer, respectively, to promote water vapor condensation and accelerate water droplet sliding. The collected water enters the filter box 204, and after preliminary filtration by the volcanic rock particle filter layer 206 and the filter screen filter layer 205, it enters the outlet. The liquid level sensor 208 detects the water volume in the water storage chamber 207. When the water volume in the water storage chamber 207 reaches a certain level, the controller 16 controls the solenoid valve 209 to open, allowing water to flow into the water storage tank 3.

[0066] Step 3: Soil moisture sensor 10 monitors the moisture of soil 8 and transmits the data to controller 16. When the moisture value of soil 8 is lower than the preset value, controller 16 controls the water pumping and conveying mechanism to pump water from the water storage container to the liquid supply chamber 7.

[0067] Specifically, the controller 16 determines whether to start the water pump 13 to water the plants based on the information provided by the soil moisture sensor 10. When the soil moisture is lower than the preset value, the controller 16 will turn on the water pump 13, draw water from the water storage tank 3 through the water pipe 14, and supply it directly to the liquid supply chamber 7 where the plant roots are located through the water nozzle 15.

[0068] During use, the device should be maintained and monitored. Specifically, the working status of system components should be checked regularly, including cleaning or replacing the filter layer, monitoring soil moisture, and assessing plant growth, to ensure the continuous and effective operation of the system.

[0069] The desert irrigation-free greening device 100 in this embodiment utilizes renewable resources such as rainwater and atmospheric water vapor as its main water source. Through water capture, water storage, and system self-sustaining, it enables vegetation survival and growth under extreme drought conditions without the need for artificial irrigation. This reduces reliance on groundwater or long-distance water transport, promoting environmental protection and sustainable development. Due to its high degree of automation, the need for manual intervention is reduced, which can significantly lower maintenance costs in the long run. Furthermore, regular inspections and filter cleaning are relatively simple and easy to perform.

[0070] The desert irrigation-free greening device 100 in this embodiment integrates multiple aspects, including water collection, storage, supply, and wind protection, forming a highly efficient and self-sufficient ecosystem. It aims to address key issues encountered during vegetation restoration in desertified areas, such as water scarcity and harsh weather conditions. The desert irrigation-free greening device 100 in this embodiment can be applied to the areas surrounding desert highways and railways, curbing desert expansion through vegetation restoration and reducing the risk of these highways and railways being buried by sandstorms. Furthermore, this device is not only suitable for greening along desert highways and railways but can also be extended to ecological restoration projects in other arid and semi-arid regions, playing a significant role in improving the local ecological environment.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope.
