Description

Technical Field

[0001] The invention relates to the field of desert vegetation restoration, and in particular to a device for irrigating vegetation using groundwater. Background Art

[0002] In the process of ecological protection and construction in my country, desertification control has become a key area that has received increasing attention. Desert areas are known for their dry climate characteristics and limited rainfall, which brings great challenges to obtaining water resources to support vegetation growth in desert environments. Vegetation is an important force to resist wind and sand invasion and promote the ecological restoration of desertified land. Its healthy growth is crucial to the success of desertification control.

[0003] However, the lack of water in desert areas poses a serious obstacle to vegetation planting. Even if irrigation is used to help vegetation survive in the initial stage, the subsequent lack of water supply often makes it difficult for vegetation to maintain vitality. Even the few vegetation that survive tenaciously will face the risk of withering due to the long-term lack of necessary water. Therefore, how to effectively absorb and store water in the desert environment to ensure that vegetation receives the necessary nourishment has become a core problem that needs to be solved urgently in the current desertification control. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiency in the prior art that vegetation planted in the desert is difficult to survive due to lack of water, and to provide a device for irrigating vegetation using groundwater.

[0005] The present invention provides a device for irrigating vegetation using groundwater, comprising:

[0006] A capillary tube bundle, wherein the bottom end of the capillary tube bundle is located below the groundwater level;

[0007] A water reservoir, the capillary tube bundle being connected to the water reservoir;

[0008] A first drip irrigation belt is arranged in the planting layer, and the first drip irrigation belt is connected to the water reservoir.

[0009] The present invention provides a device for irrigating vegetation using groundwater. The capillary phenomenon is utilized to lift groundwater below the groundwater level to the water reservoir for storage through the capillary tube bundle, and then the stored groundwater is transported to the planting layer through the first drip irrigation belt to provide a water source for irrigation of the vegetation on the planting layer, thereby alleviating the water shortage problem of vegetation planted in the desert and improving the survival rate of vegetation planted in the desert.

[0010] The capillary phenomenon refers to the phenomenon that liquid rises or falls inside a thin tubular object due to the difference between cohesive force and adhesive force and the effect of surface tension.

[0011] The water storage tank can be installed above the ground or buried below the ground, but needs to be higher than the groundwater level.

[0012] The capillary bundle may be made of stainless steel, plastic, glass or ceramic.

[0013] The drip irrigation belt is a device that uses a plastic pipe to deliver water to the roots of crops through the orifices or drippers on a capillary tube with a diameter of about 10 mm for local irrigation. Specifically, the drip irrigation belt drips water evenly and slowly drop by drop into the soil near the roots of crops through the drippers with very small outflow orifices or the drip irrigation belt itself, so that the soil in the most developed root area of ​​the crop always maintains appropriate humidity, so that the water, fertilizer, air, heat, and microbial activity of the soil are always in good condition, creating favorable conditions for high and stable yields of crops.

[0014] The groundwater mentioned here refers to the water body flowing underground, which occurs in the rock or soil below the surface, including phreatic water, confined water, etc. This water is affected by gravity and moves freely along the gaps in the rock or soil.

[0015] Preferably, the water reservoir is buried in the planting layer. Compared with placing the water reservoir directly on the ground, this solution significantly reduces the height required for the capillary bundle to lift groundwater by lowering the position of the water reservoir, thereby being able to more effectively collect and utilize more groundwater resources. In addition, the solution of burying the water reservoir in the planting layer avoids direct sunlight, effectively slows down the evaporation rate of water, further reduces the natural loss of water, and improves the water resource utilization efficiency of the entire system.

[0016] Preferably, a second drip irrigation belt is provided on the surface of the planting layer, the water reservoir is provided with a pumping device, and the second drip irrigation belt is connected to the pumping device. When there is sufficient water, the pumping device can also be used to pump the groundwater in the water reservoir into the second drip irrigation belt above the surface. The second drip irrigation belt is used to perform drip irrigation operations on the vegetation on the planting layer on the surface to ensure that the root system of the vegetation can be effectively nourished by water. In addition, through the flexible layout of the second drip irrigation belt, it is also possible to transport water resources to a wider area far away from the water source, thereby improving the irrigation efficiency and expanding the coverage area of ​​the irrigation system.

[0017] Preferably, it also includes a controller and a water level monitoring device, wherein the water level monitoring device is used to monitor whether the water level in the water reservoir is higher than a predetermined water level, and the controller is used to control the opening or closing of the pumping device. When the water level monitoring device detects that the water level in the water reservoir is higher than a predetermined water level, the controller controls the pumping device to open; when the water level monitoring device detects that the water level in the water reservoir is lower than a predetermined water level, the controller controls the pumping device to close. This solution can realize automatic control of whether to enable the second drip irrigation belt.

[0018] The water level monitoring device can use various types of water level sensors, including capacitive, resistive, float and photoelectric. The working principle of these sensors is based on detecting the changes of different physical parameters (such as capacitance, resistance, buoyancy or light reflection) caused by water level changes, and converting these changes into electrical signals for output.

[0019] Preferably, it also includes a solar panel, which is used to provide power for the pumping device, the water level monitoring device and the controller. This solution integrates solar energy technology so that the device can autonomously use solar energy, a clean energy source, for power supply without relying on an external power supply. This not only helps to reduce environmental pollution and promote sustainable development, but also effectively solves the power supply problem in remote areas or scenarios where power supply is inconvenient.

[0020] Preferably, the pumping device, the water level monitoring device and the controller are all provided with batteries. The batteries store the extra electric energy provided by the solar panels to ensure that the power supply can be maintained when the solar panels cannot continue to supply power due to natural factors such as bad weather or night, thereby avoiding the problem of energy interruption.

[0021] Preferably, the planting layer is a clay layer of a predetermined height. The clay layer may be a clay layer already existing on the surface, or may be a clay layer obtained by replacing soil layers on the original ground that are not conducive to the growth of vegetation. The clay layer is more suitable for the growth of vegetation, and at the same time, the clay layer also has good water retention properties, which can significantly improve the utilization efficiency of irrigation water resources, ensure that water is more effectively absorbed and utilized by vegetation, thereby increasing the survival rate of vegetation and improving the overall growth condition.

[0022] Preferably, the predetermined height is 0.5 meters to 1.5 meters.

[0023] Preferably, the capillary tube bundle is arranged in a well, and a water-impermeable material is provided on the well wall of the well. The main function of the water-impermeable material is to effectively reduce the capillary water loss caused by the well wall penetration during the process of lifting the groundwater through the capillary tube bundle, thereby improving the efficiency of groundwater lifting.

[0024] Preferably, the capillary tube bundle is a glass component. In this solution, the capillary tube bundle has a relatively low cost advantage due to the glass material, and the glass material ensures the long-term stable use of the capillary tube bundle with its excellent durability.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention provides a device for irrigating vegetation using groundwater. The capillary phenomenon is used to lift groundwater below the groundwater level to the water reservoir for storage through the capillary tube bundle, and then the stored groundwater is transported to the planting layer through the first drip irrigation belt to provide a water source for irrigation of the vegetation on the planting layer, thereby alleviating the water shortage problem of vegetation planted in the desert and improving the survival rate of vegetation planted in the desert.

[0047] Example 1

[0048] like Figure 1 and Figure 2 As shown, a device for irrigating vegetation using groundwater includes a capillary tube bundle 1, a water storage tank 2 and a first drip irrigation belt 5.

[0049] The bottom end of the capillary tube bundle 1 is located below the groundwater level 10. Specifically, the bottom end of the capillary tube bundle 1 may be located 1 meter to 3 meters below the groundwater level 10. A microporous filter layer may also be provided at the bottom end of the capillary tube bundle 1 to prevent soil particles or impurities from clogging the capillary tube bundle 1.

[0050] The top end of the capillary tube bundle 1 is connected to the water reservoir 2 .

[0051] The first drip irrigation belt 5 is arranged in the planting layer 9, and the first drip irrigation belt 5 is connected with the water reservoir 2. Specifically, the first drip irrigation belt 5 is arranged at the same level as or lower than the bottom of the water reservoir 2, and the first drip irrigation belt 5 is arranged horizontally in the planting layer 9. The first drip irrigation belt 5 adopts a gravity nozzle, and the purpose of this is to ensure that the water in the water reservoir 2 can flow smoothly into the first drip irrigation belt 5 without external assistance, only by natural gravity, and then flow into the planting layer 9 through the gravity nozzle.

[0052] In an optional embodiment, the water reservoir 2 can be buried in the planting layer 9. The water reservoir 2 can be built with bricks so that the size and shape can be customized according to specific needs; or a pre-made plastic water tank can be used, which usually has a standardized size and capacity for easy installation and use. The side wall of the water reservoir 2 is connected to the top of the capillary bundle 1, so that the capillary bundle 1 and the water reservoir 2 are connected.

[0053] In an optional embodiment, the surface of the planting layer 9 may be provided with a second drip irrigation belt 8, the water storage tank 2 is provided with a pumping device 4, and the second drip irrigation belt 8 is connected to the pumping device 4. The pumping device 4 may be a submersible pump or a self-priming pumping device, and is arranged inside the water storage tank 2. The pumping device 4 is connected to the second drip irrigation belt 8 through a PVC pipe.

[0054] In an optional embodiment, a controller 7 and a water level monitoring device 3 may also be included. The water level monitoring device 3 is used to monitor whether the water level in the water reservoir 2 is higher than a predetermined water level, and the controller 7 is used to control the opening or closing of the pumping device 4. The water level monitoring device 3 may be located inside the water reservoir 2 and connected to the inner wall of the water reservoir 2. When the water level monitoring device 3 detects that the water level in the water reservoir 2 exceeds half of its maximum allowable water level, the controller 7 controls the pumping device 4 to open, thereby sending the water in the water tank to the second drip irrigation belt 8.

[0055] In an optional embodiment, a solar panel 6 may be further included, and the solar panel 6 is used to provide power for the pumping device 4, the water level monitoring device 3 and the controller 7. The solar panel 6 is arranged on the ground near the water storage tank 2, and the solar panel 6 is installed on the ground through a column.

[0056] In an optional embodiment, the pumping device 4, the water level monitoring device 3 and the controller 7 may all be provided with batteries. When the power provided by the solar panel 6 is sufficient, the excess power can be used to charge the battery; when the solar panel 6 cannot provide power or provides insufficient power, the battery can continue to supply power to the pumping device 4, the water level monitoring device 3 or the controller 7.

[0057] In an optional embodiment, the planting layer 9 can be a clay layer of a predetermined height. Specifically, the clay layer is obtained through a replacement process, and the original planting layer 9 soil type is desert soil, which is loose in texture and poor in water and fertilizer retention, and cannot meet the basic needs of plant growth. Therefore, soil improvement measures are taken to use clay that is more suitable for plant growth and development for replacement operations to optimize the soil structure, improve soil fertility, and ensure the smooth progress of planting activities.

[0058] In an optional implementation, the predetermined height may be 0.5 meters to 1.5 meters, and the specific height may be 0.5 meters, 0.8 meters, 1.0 meters, 1.2 meters, 1.4 meters, or 1.5 meters.

[0059] In an optional embodiment, the capillary bundle 1 can be arranged in a well, and the well wall of the well can have an impermeable material. Specifically, the well is formed by drilling operations. During the drilling operation, the clay layer is penetrated until the groundwater level reaches below 10. To ensure the waterproof effect, the impermeable material is brushed on the well wall, and its coverage range must at least extend from the bottom of the well to half the height of the clay layer.

[0060] In an optional embodiment, the capillary bundle 1 may be a glass component. Specifically, the capillary bundle 1 may be composed of glass capillaries. The inner diameter of the glass capillaries may be 0.3 mm to 2.0 mm, and the specific inner diameter may be 0.3 mm, 0.5 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.6 mm, 1.8 mm, or 2.0 mm.

[0061] Specifically, clay is used to replace the area from the desert surface to 1m below the desert surface to form the clay layer. Subsequently, drilling is started from the surface of the clay layer downward until the position of 2 meters below the groundwater level 10 is reached, thereby forming the wellbore and the well wall structure around it. Then, the well wall is treated with impermeable materials for anti-seepage, and the anti-seepage treatment area is from 0.5m below the clay layer after replacement to the area at the bottom of the well. After the anti-seepage treatment is completed, the capillary bundle 1 is filled into the wellbore, and the bottom of the capillary bundle 1 is in contact with the groundwater.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
