Description

Technical Field

[0001] This utility model relates to the field of soil water replenishment equipment, specifically to a water replenishment device for arid desert ecosystems based on micro-water vapor self-circulation. Background Technology

[0002] Arid desert regions suffer from extreme water scarcity, characterized by sparse rainfall, intense evaporation, and poor soil water retention, severely hindering vegetation restoration and ecosystem stability. Traditional water replenishment methods, such as long-distance water transfer and deep well drilling, have the following shortcomings:

[0003] Long-distance water diversion projects involve huge investments, long construction periods, and high operation and maintenance costs, and are limited by geographical conditions, making them difficult to cover vast desert areas. Drilling deep wells, on the other hand, relies excessively on finite and potentially non-renewable groundwater resources, and long-term extraction can lead to water level decline or even depletion, potentially causing secondary problems such as soil salinization. These methods are not only cost-effective and difficult to promote on a large scale in economically underdeveloped desert areas with weak infrastructure, but also lack sustainability and cannot effectively address the long-term water replenishment needs of desert ecosystems. Therefore, there is an urgent need to develop a water replenishment device that can be adapted to local conditions, cost-effectively, and sustainably utilize local desert environmental resources for water collection and replenishment. Utility Model Content

[0004] The purpose of this invention is to provide a water replenishment device for arid desert ecosystems based on micro-water vapor self-circulation, which solves the problem that existing water replenishment devices are unable to reasonably and effectively replenish desert soil moisture.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A water replenishment device for arid desert ecosystems based on micro-moisture self-circulation includes a water replenishment pipe with a seepage port at its bottom, buried in the desert soil. A rain collection tray and an air supply mechanism are connected to both ends of the water replenishment pipe, both located above the desert soil. A humidity sensor is installed on the water replenishment pipe to detect soil moisture, and a humidity sensor is installed on the air supply mechanism to detect air humidity. The air supply mechanism delivers micro-moisture into the water replenishment pipe when the air humidity is not less than the soil humidity, allowing air carrying micro-moisture to enter the pipe. The micro-moisture condenses in the pipe, and the condensed water seeps into the soil through the seepage port, replenishing the desert soil's moisture.

[0007] As a further optimization of this utility model, the air supply mechanism includes a guide plate connected to the water supply pipe, a turbine ventilator located above the guide plate, and a valve located at the bottom of the guide plate.

[0008] As a further optimization of this utility model, the turbine ventilator is provided with a mounting rod at the bottom, and the mounting rod is provided with several fan blades.

[0009] As a further optimization of this utility model, the air supply mechanism also includes a support frame, the guide plate is disposed on the bottom plate of the support frame, and the turbine ventilator is disposed on the top plate of the support frame.

[0010] As a further optimization of this utility model, the air supply mechanism further includes an electric drive module and a photovoltaic power generation module. The photovoltaic power generation module is used to supply power to the electric drive module. The electric drive module includes a motor, which is used to drive the turbine ventilator to rotate.

[0011] As a further optimization of this utility model, the air supply mechanism consists of an air catcher and a guide tube. The air catcher is connected to a water supply pipe, and the guide tube is in the shape of an inverted cone and fixed on the top of the air catcher. An annular air inlet is formed between the guide tube and the air catcher.

[0012] As a further optimization of this utility model, a connecting pipe is provided between the valve and the rain collection plate and the water supply pipe.

[0013] As a further optimization of this utility model, the water supply pipe is inclined and the slope of the water supply pipe is 0.5%-1%.

[0014] As a further optimization of this utility model, the diameter of the leakage port is 1-3mm.

[0015] The beneficial effects of this utility model are as follows:

[0016] Rainwater is collected by a rain collection tray and flows through a connecting pipe into a water supply pipe buried in the soil. Because the underground pipe is higher in the direction of the water supply pipe outlet, when it rains, the rainwater flows along the pipe and can be stored in the horizontal pipe and flow towards the air inlet side. It also slowly seeps into the soil through the seepage outlet, keeping the soil moisture away from the surface. This is suitable for desert ecological environments and improves the water retention capacity of the desert ecological environment where plants live.

[0017] Taking advantage of the large diurnal temperature range and strong winds in arid regions, a wind-driven air supply mechanism is installed on the side of the water supply pipe away from the rain collection tray. This allows outside air carrying a trace amount of moisture to be introduced into the water supply pipe. When the warm, humid air enters the pipe, it comes into contact with the low temperature of the inner wall of the pipe, causing the moisture in the air to condense into water droplets. These droplets then seep into the soil through the leakage outlets, providing moisture to the vegetation, promoting vegetation growth, and mitigating the stress of drought on the ecosystem. This water supply device is cost-effective and allows for the sustainable use of local desert resources for water replenishment. Attached Figure Description

[0025] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] First Embodiment

[0027] like Figure 1-3 As shown, this embodiment relates to a water replenishment device for arid desert ecosystems based on micro-moisture self-circulation. The device includes a water replenishment pipe 1 made of corrosion-resistant and pressure-resistant circular tubing, with a leak outlet 2 at its bottom. Both ends of the water replenishment pipe 1 are connected to a rain collection tray 3 and an air supply mechanism 4, respectively, both located above the desert soil. In this embodiment, the water replenishment pipe 1 is preferably a PE pipe with a diameter of approximately 10 cm. The water replenishment pipe 1 is buried in the soil of forest or grassland in the desert at a depth of 20-40 cm, preferably 30 cm in this embodiment. The end of the water replenishment pipe 1 furthest from the rain collection tray 3 is slightly inclined downwards, with a slope of 0.5%-1%. The diameter of the leak outlet 2 is 1-3 mm, and the rain collection tray 3, with a diameter of approximately 30 cm, is used to collect rainwater. When the air humidity is not less than the soil humidity, the water replenishment device delivers air carrying micro-moisture into the water replenishment pipe 1 through the air supply mechanism 4.

[0028] During rainfall, rainwater is collected by the rain collection tray 3. The port of the water supply pipe 1 closest to the rain collection tray 3 is the air outlet, and the other port is the air inlet. Rainwater enters the interior of the water supply pipe 1 from the connecting pipe 7 on the air outlet side. Because the underground pipes in the direction of the air outlet of the water supply pipe 1 are relatively high, during rainfall, the rainwater flows along the pipes and can be retained in the horizontal pipes, flowing towards the air inlet side, and slowly seeping into the soil through the seepage outlet 2.

[0029] like Figure 3 As shown, this embodiment utilizes the large diurnal temperature range and strong winds characteristic of desert regions by installing a ground-level fan turbine to achieve sustainable self-circulation operation of the water replenishment device using wind energy. The fan turbine is the air supply mechanism 4 in this embodiment. The fan turbine includes a guide plate 41 connected to the water replenishment pipe 1, a turbine ventilator 42 located above the guide plate 41, and a valve 43 located at the bottom of the guide plate 41. The valve 43 is a butterfly valve or a gate valve. The turbine ventilator 42 has a mounting rod 44 at its bottom, and several fan blades 45 are provided on the mounting rod 44.

[0030] Both ends of the water supply pipe 1 are fixed with connecting pipes 7. The connecting pipes 7 are made of a material that is resistant to high temperatures and corrosion and has good sealing properties. In this embodiment, the connecting pipes 7 are preferably CPVC plastic pipes. The inner wall of the pipe is smooth to reduce resistance during airflow. The water supply pipe 1 is connected to the valve 43 and the rain collection tray 3 through the two connecting pipes 7. The fan blades 45 are made of lightweight and high-strength materials. In this embodiment, the fan blades 45 are preferably made of carbon fiber composite material. The diameter of the fan blades 45 is 1-1.5m to reduce the starting wind speed, effectively capture wind energy, and improve working efficiency.

[0031] The water supply pipe 1 is equipped with a humidity sensor 5 for detecting soil moisture, and the air supply mechanism 4 is equipped with a humidity sensor 6 for detecting air humidity. Both humidity sensors 5 and 6 are preferably HYT221 models. The air supply mechanism 4 is connected to the humidity sensors 5 and 6 via a controller. The controller compares the air humidity with the soil moisture and supplies air to the water supply pipe 1 when the air humidity is not less than the soil humidity. Conversely, when the air humidity is less than the soil humidity, the valve 43 closes to prevent dry air from entering the water supply pipe 1.

[0032] Because the underground temperature is relatively stable and low, the controller, in conjunction with humidity sensor 5 and humidity sensor 6, keeps valve 43 open when it detects that the air humidity is not less than the soil humidity. The circular air inlet of turbine ventilator 42 is set upwards, and turbine ventilator 42 rotates under air-cooled drive. Warm and humid air above turbine ventilator 42 enters turbine ventilator 42 and flows obliquely downwards through turbine ventilator 42. Turbine ventilator 42 synchronously drives mounting rod 44 and fan blade 45 to rotate. Fan blade 45 passes the air around the lower part of turbine ventilator 42 into the connecting pipe 7 on the side of the air inlet of water supply pipe 1.

[0033] When warm, humid air is introduced into the water supply pipe 1, it comes into contact with the low temperature of the inner wall of the pipe, causing the micro-water vapor in the air to condense into water droplets. As the moisture continuously condenses and accumulates, it seeps into the soil through the infiltration port 2, providing water to the vegetation, promoting vegetation growth, and mitigating the stress of drought on the ecosystem. By condensing water vapor and replenishing the soil, a stable water source is provided for vegetation, increasing soil moisture, improving soil water conditions, expanding the area suitable for vegetation growth, promoting the natural growth and reproduction of native drought-resistant plants in desert areas, and increasing vegetation cover. Vegetation restoration can effectively stabilize sand dunes, reduce wind erosion, prevent desert expansion, and protect the soil and ecological environment.

[0034] Stable vegetation communities can form a soil cover layer, reduce surface temperature, and decrease soil moisture evaporation. At the same time, vegetation roots can improve soil structure, increase soil water retention and aeration, provide a better living environment for soil microorganisms and other organisms, promote the material cycle and energy flow of the ecosystem, enhance the stability and resistance to disturbance of the entire desert ecosystem, help build a relatively complete ecosystem, and improve biodiversity.

[0035] Compared to traditional methods of obtaining water resources, such as long-distance water diversion and drilling deep wells, this water replenishment device utilizes local natural conditions such as diurnal temperature variations and wind energy to collect condensate locally. It eliminates the need for large-scale engineering construction and high operating and maintenance costs, reducing the cost of water acquisition. This makes it particularly suitable for widespread application in economically underdeveloped and infrastructure-deficient arid desert regions, providing a low-cost, sustainable water resource solution for local ecological governance and economic development. The restoration of vegetation and improvement of the ecological environment can drive the development of related industries such as ecotourism in arid desert areas, increasing employment opportunities and residents' income. It also benefits local agricultural and pastoral production, improves land productivity, ensures the survival and development of ecological migrants, promotes the sustainable economic and social development of arid desert regions, and achieves a virtuous cycle of ecological and economic benefits.

[0036] In addition, the air supply mechanism 4 also includes a support frame 46, a guide plate 41 disposed on the bottom plate of the support frame 46, and a turbine ventilator 42 disposed on the top plate of the support frame 46. Humidity sensor 5 is fixedly installed on the top inner side of the water supply pipe 1, and humidity sensor 6 is fixedly installed on the top plate of the support frame 46. Specifically, the turbine ventilator 42 includes a fixed ring, a rotating frame rotatably connected to the fixed ring, and multiple arc-shaped turbine blades fixed on the rotating frame. The turbine blades are evenly distributed on the outer side of the rotating frame. The mounting rod 44 is fixedly disposed at the bottom end of the rotating frame. The fixed ring of the turbine ventilator 42 is fixedly installed on the top plate of the support frame 46. When wind force acts on the turbine blades, the turbine blades drive the rotating frame to rotate relative to the fixed ring, and the mounting rod 44 and the fan blades 45 rotate synchronously with the rotating frame. The top plate of the support frame 46 has a through hole corresponding to the fixed ring for assembling the fixed ring of the turbine ventilator 42. The support frame 46 provides positioning support for the guide plate 41 and the turbine ventilator 42.

[0037] Second Embodiment

[0038] like Figure 4 and Figure 5 As shown, this embodiment relates to another water replenishment device for arid desert ecosystems based on micro-water vapor self-circulation. The difference between this embodiment and the previous embodiment is that the air supply mechanism 4 in this embodiment further includes an electric drive module and a photovoltaic power generation module, as well as a speed sensor for detecting the rotational speed of the fan blades 45. The speed sensor in this embodiment is preferably a Hall sensor, which is installed inside the fixing ring of the turbine ventilator 42. It measures the rotational speed of the fan blades 45 by detecting the rotational speed of the turbine ventilator 42's rotating frame. The Hall sensor is preferably a HAL-506S model, and the turbine ventilator 42's rotating frame has a gear corresponding to the Hall sensor. The photovoltaic power generation module supplies power to the electric drive module. The electric drive module includes a motor 47, whose base is fixedly mounted above the top plate of the support frame 46, and whose output shaft is fixedly mounted on the rotating frame of the turbine ventilator 42. The motor 47 drives the turbine ventilator 42 to rotate. It should be noted that the output shaft of the motor 47 does not have a self-locking function; when the motor 47 is de-energized, its output shaft can rotate freely, ensuring that the turbine ventilator 42 can rotate under wind power.

[0039] When humidity sensors 5 and 6 detect that the air humidity is not less than the soil humidity, if the speed sensor detects that the fan blade 45's speed is less than a set value, the controller starts motor 47. Motor 47 rotates the rotating frame of the turbine ventilator 42, causing the fan blade 45 to rotate rapidly. This allows solar energy to circulate micro-moisture from the air into the water supply pipe 1 in windless or low-wind-speed environments, enabling continued condensation and accumulation of moisture in the pipe. Alternatively, in other embodiments, an encoder can be used instead of a Hall sensor to measure the fan blade 45's speed, or a wind speed sensor can be used instead of a speed sensor. When the wind speed is below a threshold, the electric drive module drives the turbine ventilator 42 to rotate.

[0040] Third Embodiment

[0041] like Figure 6 As shown, this embodiment relates to another water replenishment device for arid desert ecosystems based on micro-water vapor self-circulation. The difference between this embodiment and the previous two embodiments is that the air supply mechanism 4 in this embodiment is a wind catcher, and the wind catcher replaces the fan turbine in this embodiment.

[0042] The wind catcher consists of a wind catcher hood 48 and a guide tube 49. The wind catcher hood 48 is connected to the water supply pipe 1. The guide tube 49 is inverted cone shape and fixed on the top of the wind catcher hood 48. An annular air inlet is formed between the guide tube 49 and the wind catcher hood 48.

[0043] When there is natural wind outside the water supply device, the natural wind enters the wind catcher through the annular air inlet and is guided by the guide fluid 49. The wind catcher hood 48 blocks the natural wind entering the wind catcher to prevent it from flowing out radially along the wind catcher. In this embodiment, humidity sensor 5 and humidity sensor 6 are also provided, as well as valve 43. Humidity sensor 5 is fixed inside the water supply pipe 1, humidity sensor 6 is fixed on the wind catcher hood 48 or the guide fluid 49, and valve 43 is fixed at the bottom of the wind catcher hood 48. When the air humidity is greater than or equal to the soil humidity, valve 43 opens, allowing the natural wind to carry micro-moisture into the water supply pipe 1.

[0044] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of this utility model.
