Description

Technical Field

[0001] The invention belongs to the technical field of water-retaining and sand-fixing equipment, and in particular relates to a sand-fixing and water-retaining device and method for soil and water conservation. Background Art

[0002] At a time when ecological environment protection and sustainable development are receiving much attention, the importance of soil and water conservation has become increasingly prominent. In deserts or arid areas, the situation is also not optimistic, so it is of far-reaching significance to implement measures to fix sand and conserve water in the desert. As an important ecological engineering measure, sand fixation and water conservation in the desert can effectively curb the expansion of the desert, prevent the intensification of land desertification, provide necessary conditions for vegetation growth, promote the stability and balance of the ecosystem, increase biodiversity, regulate local climate, reduce the harm of wind and sand, and improve the ecological environment.

[0003] At present, when carrying out desert sand fixation and water conservation measures, some sand fixation and water conservation equipment is often used to assist drought-resistant plants to form a green barrier to fix sand, prevent wind erosion and sandstorms, and improve the ecological environment. At present, most sand fixation and water conservation equipment collects rainwater as the main water source, but due to the influence of the desert climate, the precipitation in the desert area is extremely low, and the precipitation is mainly concentrated in a certain season, and the precipitation is extremely unstable. For example, the average annual precipitation in the Tengger Desert area is only between 100mm and 200mm. The precipitation in this area is concentrated between May and September, accounting for about 80% of the whole year, of which summer accounts for more than half of the whole year. Rain and heat are in the same period, and the annual and seasonal variations of precipitation are large. For example, the average annual precipitation in the Ulan Buh Desert is only 140mm to 169.6mm. The climate in this area is arid and belongs to the temperate continental desert climate. However, the annual average evaporation is as high as 2395.6mm to 2866.9mm, which is much greater than the precipitation. The precipitation is unevenly distributed in time and space, and the interannual variation is large.

[0004] Therefore, existing sand fixation and water conservation equipment is difficult to effectively and continuously collect rainwater to implement water conservation measures. In practical applications, artificial interference is required during non-precipitation seasons to take relevant measures to achieve artificial water supply for plants during non-precipitation seasons. This requires a large number of transportation tools and manpower, and the water loss during transportation is also relatively large, resulting in high water supply costs and making it difficult to maintain large-scale plant cultivation in the long term. For example, the Chinese invention patent with the publication number CN107820909B discloses a sand fixation and water conservation device. The upper end of the device is open, and a water collection groove is provided on the outer wall to facilitate rainwater collection. The collected water can directly enter the desert surface layer through the water conservation layer. However, this device is difficult to effectively and continuously collect rainwater in desert areas. This is mainly because the precipitation in desert areas is low and the precipitation time is relatively concentrated, rather than evenly distributed throughout the year. Therefore, during non-precipitation seasons, this device cannot provide water. Moreover, precisely during non-precipitation seasons, plants need to be supplemented with water, but at this time, the device cannot provide water because it has not collected rainwater, so artificial water supply for plants is required, resulting in high water supply costs. Another example is the Chinese invention patent with the publication number CN118923389B, which discloses a water conservation and sand fixation device and method for desert windbreak and sand fixation forests. When it rains, the collection component is used to guide rainwater into the sand in the conical inner frame, and at the same time, the water receiving area is increased, so that the rainwater enters the water storage unit for storage. This device is also difficult to effectively and continuously collect rainwater in desert areas. In addition, this device can also be supplemented with water into the water storage unit through an external water supply device to achieve artificial interference, resulting in high water supply costs and making it difficult to maintain large-scale plant cultivation in the long term. Summary of the Invention

[0005] In view of the above problems, the purpose of the present invention is to provide a sand fixation and water conservation device and method for soil and water conservation, which is not restricted by rainfall and can also achieve the functions of sand fixation and water conservation during non-rainy periods.

[0006] The technical solution of the present invention is: A sand fixation and water conservation device for soil and water conservation, comprising a support part, a plurality of water collection parts, and a sand fixation belt group.

[0007] The bottom of the support part is used to be inserted into the soil body, and the support part forms a planting cavity on the soil body, and the planting cavity is used for planting plants.

[0008] Multiple water collection parts are distributed around the support part. Each water collection part includes a first pipe body, a second pipe body, a water diversion tray, an air introduction part, and a water outlet part and a water diversion net. A water storage cavity is arranged at the lower end of the first pipe body. The second pipe body is coaxially arranged with the first pipe body and is located inside the first pipe body. The upper end of the second pipe body is fixed to the inner wall of the first pipe body. The outer wall of the second pipe body and the inner wall of the first pipe body form a water diversion channel, and the water diversion channel is communicated with the water storage cavity. The water diversion tray is sleeved on the first pipe body, and a water diversion cavity is arranged on the water diversion tray. The water diversion cavity is communicated with the water diversion channel. The air introduction part is communicated with the second pipe body and is used for introducing air into the second pipe body. The water outlet part has a water inlet end and a water outlet end. A water inlet pipe is arranged at the water inlet end, and the water inlet of the water inlet pipe is located in the water storage cavity. One side of the water diversion net is fixed to the support part, and the other side is fixed to the water diversion tray and is located in the water diversion cavity. The side of the water diversion net located on the support part is higher than the side located on the water diversion tray.

[0009] The sand fixation belt group has a plurality of liquid dripping ports. The liquid dripping ports are connected with the water outlet end through a water outlet pipe, and the water in the water storage cavity is led to the liquid dripping ports through the water outlet part for discharge.

[0010] The water collection part realizes effective water collection through the air introduction part and the water diversion net. Among them, the air introduction part is based on the temperature difference between above the ground surface and below the ground layer. When the air is led from the ground surface to underground, the moisture in the air condenses into water droplets, and then enters the water storage cavity to realize water collection. Since the side of the water diversion net located on the support part is higher than the side located on the water diversion tray, it is in an inclined shape. The water diversion net serves as a diversion part during rainfall, guiding rainwater to the water diversion cavity on the water diversion tray, and then entering the water storage cavity through the water diversion channel to realize water collection. During the period without rainfall, based on the day-night temperature difference, the surface temperature of the water diversion net at night will be lower than the temperature of the surrounding air. When the early morning temperature reaches the dew point temperature, the water vapor in the air reaches a saturated state and will condense into small water droplets on the surface of the water diversion net. In addition, in some use areas with high humidity, there is sufficient water vapor in the air. When these water vapors encounter the relatively low-temperature water diversion net, they will condense into water droplets.

[0011] The water collection part cooperates with the sand fixation belt group to effectively improve the environment for the planted plants. Specifically, it has functions such as wind blocking and water supply for the planted soil body. Among them, the water outlet part leads the water in the water storage cavity to the liquid dripping ports of the sand fixation belt group for discharge, realizing precise drip irrigation, reducing water waste, improving the utilization efficiency of water resources, and at the same time better meeting the water requirements of the soil body and plants near the sand fixation belt, providing a good environment for the growth of plants, being beneficial to improving the survival rate of plants, and further playing the role of plants in soil and water conservation and sand fixation. The water diversion net and the sand fixation belt group have a better wind blocking effect and can cooperate to maintain the humidity of the soil body, thus achieving a good sand fixation effect. And multiple water collection parts are arranged around the support part, combined with the sand fixation belt group to form a relatively complete sand fixation and water conservation system, further enhancing the ability of sand fixation and water conservation.

[0012] Further, the water storage cavity is in an olive spherical structure. A funnel is provided at the lower end of the second pipe body, and a condensation rack is arranged inside the water storage cavity, and the condensation rack is located directly below the funnel. In actual use, the air guiding member introduces air from the upper end of the second pipe body, and the air flows through the second pipe body and reaches the water storage cavity. The funnel provided at the lower end of the second pipe body can effectively increase the diameter of the air outlet end, which is beneficial to the dispersion of air in the water storage cavity, and then contact with the condensation rack, so that the moisture in the air can effectively condense on the condensation rack.

[0013] Furthermore, the condensation rack includes a condensation ring, a support frame and a cover body. The condensation ring is fixed on the inner wall of the water storage cavity, the support frame is fixed on the inner ring of the condensation ring and has a support rod, the support rod is distributed along the axis of the second pipe body, and the cover body is fixed on the support rod and is located at the funnel outlet. The outer wall of the cover body and the inner wall of the funnel form a gas channel. The cover body is fixed on the support rod and is located at the funnel outlet, and its outer wall and the inner wall of the funnel form a gas channel. This design can, on the one hand, guide the air discharged from the funnel of the second pipe body to flow in the gas channel, so that the air fully contacts the cover body, and utilize the lower temperature of the cover body to promote the condensation of water vapor in the air; on the other hand, the cover body effectively blocks the outlet of the funnel, which can effectively prompt the air to be discharged from the water diversion channel after condensation, avoid the influence of air accumulation on the gas exchange and water flow transmission in the second pipe body, maintain the coherence and stability of the operation of the entire device, and ensure the efficient operation of the water collection and transmission system.

[0014] Further, fin groups are arranged on the first pipe body, and the fin groups are close to the connection between the first pipe body and the water storage cavity; the fin groups include a plurality of annular sheets distributed in sequence along the length of the first pipe body, the annular sheets are embedded on the first pipe body, and the inner diameter of the inner ring of the annular sheet is larger than the diameter of the second pipe body. The fin groups effectively block the effective path of the water diversion channel. On the one hand, the fin groups are used to further perform heat exchange on the air discharged from the water diversion channel to avoid poor heat exchange and poor moisture condensation effect caused by too high air flow rate. On the other hand, since the water diversion channel is essentially to introduce the water collected by the water diversion network into the water storage cavity, the inner diameter of the inner ring of the annular sheet is larger than the diameter of the second pipe body. This design forms a structure similar to a step in the first pipe body. When the water in the water diversion channel flows down, the annular sheet can buffer and guide the water flow, so that the water flow enters the water storage cavity more smoothly, avoiding splashing of water in the water storage cavity caused by water flow impact, reducing water loss, and having the effect of optimizing the water flow direction.

[0015] Further, the water collection part further includes a driving member, and the driving member is connected to the air guiding member and the water outlet member. The driving member is used to convert wind energy into mechanical energy to drive the air guiding member and the water outlet member.

[0016] Further, there are 3 to 6 water collection parts, and the sand fixation belt group is wound around the water collection parts to form a regular polygon with the water collection parts.

[0017] Furthermore, the sand fixation belt group includes a plurality of sand fixation belts, each sand fixation belt is correspondingly distributed between two adjacent water collection parts one by one, both ends of the sand fixation belt are respectively fixed on two adjacent pipe bodies, a water diversion channel distributed along the belt length direction is arranged in the sand fixation belt, the liquid dropping port is arranged on the sand fixation belt, and the liquid dropping port is communicated with the water outlet pipe through the water diversion channel. The plurality of sand fixation belts are correspondingly distributed between two adjacent water collection parts one by one, making full use of the space around the water collection parts, forming a tight and uniform protection network. This layout enables the water collected by the water collection parts to be quickly and efficiently transported to each liquid dropping port through the water outlet pipe and the water diversion channel in the sand fixation belt, ensuring that the soil around the sand fixation belt can obtain water supply in time and realizing the coordinated operation of the water collection and sand fixation functions. Moreover, both ends of the sand fixation belt are respectively fixed on two adjacent first pipe bodies, providing a stable support point for the sand fixation belt. This not only enables the sand fixation belt to be firmly fixed on the sandy land, effectively resisting the erosion and pulling of wind and sand and being not prone to displacement or fracture, but also enhances the structural integrity of the entire device by connecting multiple water collection parts, improving the stability and reliability of the device in a complex wind-sand environment. The combined use of a plurality of sand fixation belts greatly expands the sand fixation protection area. The adjacent sand fixation belts cooperate with each other to form a continuous sand fixation barrier, which can effectively prevent the movement of wind and sand and fix the sandy soil. At the same time, the liquid dropping port continuously replenishes water to the soil around the sand fixation belt, helping to maintain the soil humidity, promoting the growth of sand fixation plants, further enhancing the sand fixation effect, and gradually improving the sandy land ecological environment.

[0018] Furthermore, an ecological wall is provided on the sand fixation belt. The ecological wall includes ecological straws distributed along the length direction of the sand fixation belt. The ecological straws distributed along the length direction of the sand fixation belt form the ecological wall, and their staggered structure can effectively reduce the wind-sand flow velocity and intercept sand dust particles. The physical blocking effect of the straw itself can directly weaken the erosion force of the wind-sand on the soil surface, reduce the wind erosion phenomenon, and act like a natural windbreak wall, forming the first line of defense on the wind-sand flow path and stabilizing the surface structure of the sand. The ecological straw will gradually decompose in the natural environment, releasing nutrients such as organic matter and humus into the soil. These components can improve the poor soil structure of the sand, increase the soil porosity, enhance the soil's water and fertilizer retention capacity, create a more favorable environment for the growth of the roots of sand-fixing plants, promote the rooting of plants, and form a virtuous cycle of "straw fixing sand - plant growth - root fixing soil". The ecological straw is widely sourced and is a residue of agricultural production. Using it to construct the ecological wall of the sand fixation belt realizes the reuse of resources and greatly reduces the material cost of the sand fixation project. At the same time, the straw can be naturally degraded, without causing secondary pollution to the environment, which conforms to the concept of sustainable development. Even if there is loss in the later stage, it can be conveniently replenished and updated to maintain the long-term effectiveness of the sand fixation system. The ecological straw has a certain water absorption capacity, can absorb and store part of the water discharged from the drip orifice, and reduce the rapid evaporation and infiltration loss of water. During the dry period, the water stored in the straw is slowly released, continuously replenishing water for the surrounding soil and plants, playing a role similar to a "miniature water storage part" and further enhancing the water retention performance of the sand fixation belt.

[0019] Furthermore, a through groove is provided along the length direction of the upper edge of the sand fixation belt. A traction rope is arranged in the through groove, and a plurality of restraint rings are evenly distributed on the traction rope. After the ecological straws are bundled into bundles, they are inserted into the restraint rings, and the lower ends of the ecological straws are inserted into the soil. This design makes the ecological straws not easily blown down or pulled out in the sandy environment, effectively resists the impact of wind and sand, ensures the long-term stability of the ecological wall, and continuously plays the role of sand fixation. By fixing the ecological straws with the restraint rings, the installation process is simple and convenient, without the need for complex tools and techniques, and the ecological wall can be quickly built. When the ecological straws need to be replaced due to natural degradation or external damage, only the old straws need to be taken out of the restraint rings and new straw bundles are inserted, which greatly reduces the maintenance difficulty and cost and is convenient for the long-term management and continuous promotion of the sand fixation project. The restraint rings are evenly distributed along the traction rope, ensuring the uniform arrangement of the ecological straws on the sand fixation belt. This uniform distribution makes the blocking effect of the ecological wall on the wind and sand more balanced, avoids the emergence of weak protection points, and is also conducive to the uniform diffusion of water between the ecological straws, promotes the uniform distribution of soil humidity, and creates a more stable environment for the growth of sand fixation plants. The traction rope can be adjusted in position or tightened in the through groove according to actual needs, thereby changing the position and density of the restraint rings. In areas with different sandstorm intensities, the number of ecological straws can be flexibly increased or decreased to adjust the protection intensity of the ecological wall; in areas with different plant growth conditions, the restraint rings can also be adjusted to reserve space for plant growth, improving the adaptability of the sand fixation device to complex environments. The existence of the traction rope and the restraint rings not only enhances the structural stability but also does not hinder the natural degradation process of the ecological straws. When the ecological straws decompose in the restraint rings, their nutrients can still effectively dissolve into the soil. If the materials of the restraint rings and the traction rope are made of environmentally friendly and degradable materials, they can participate in the ecological cycle together with the ecological straws, realizing the organic unity of structural functions and ecological benefits.

[0020] A sand fixation and water conservation method for soil and water conservation, which uses the sand fixation and water conservation device for sand fixation and water conservation, specifically includes the following steps: Plant plants in the planting cavity.

[0021] When it rains, the rainwater is led to the water diversion cavity through the water diversion net and flows into the water storage cavity through the water diversion channel to complete water collection. When it does not rain, the water diversion net collects the small water droplets condensed on its surface and leads them to the water diversion cavity, and then flows into the water storage cavity through the water diversion channel to complete water collection; moreover, the air intake member introduces air into the second pipe body, and when the air passes through the second pipe body, a temperature difference is generated from above the ground into the ground. The water vapor in the air cools and condenses into small water droplets during the process of passing into the ground, and then flows into the water storage cavity to complete water collection. The water in the water storage cavity is led to the drip orifice through the water outlet member and discharged into the soil around the plants.

[0022] The sand fixation belt group and the water diversion net are both used for wind prevention and sand fixation.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the air guiding member and the water guiding net of the water collection part, the present invention can effectively collect the surrounding moisture and store it in the water storage cavity at the lower end of the first pipe body, providing guarantee for subsequent water supply and adapting to arid and water-scarce environments. Among them, based on the temperature difference between above the ground surface and below the ground layer, the air guiding member condenses the moisture in the air into water droplets when guiding the air from the ground surface to underground, and then enters the water storage cavity to realize water collection. The water guiding net is used to collect rainwater during rainfall or small water droplets condensed due to the day-night temperature difference on its surface when there is no rainfall, and then enters the water storage cavity through the water guiding channel to realize water collection. The water outlet member guides the water in the water storage cavity to the liquid dripping ports of the sand fixation belt group for discharge, realizing precise drip irrigation, reducing water waste, improving the utilization efficiency of water resources, and at the same time better meeting the water requirements of the soil body and plants near the sand fixation belt, providing a good environment for the growth of plants, being beneficial to improving the survival rate of plants, and further playing the role of plants in soil and water conservation and sand fixation. The water guiding net and the sand fixation belt group have a better wind blocking effect, can cooperate to maintain the humidity of the soil body, and thus achieve a good sand fixation effect. And a plurality of water collection parts are arranged around the support part, combined with the sand fixation belt group to form a relatively complete sand fixation and water conservation system, further enhancing the ability of sand fixation and water conservation.

[0028] It should be noted that the circuit connections involved in the present invention all adopt conventional circuit connection methods and do not involve any innovation.

[0029] Embodiment 1 As Figure 1 shown, a sand fixation and water conservation device for soil and water conservation includes a support part 1, a plurality of water collection parts 2, and a sand fixation belt group 3.

[0030] The bottom of the support part 1 is used to be inserted into the soil. The support part 1 forms a planting cavity on the soil, and the planting cavity is used for planting plants. Among them, in this embodiment, the support part 1 includes a plurality of rod bodies and two fixing rings. The tops of the plurality of rod bodies are rotatably arranged on one of the fixing rings, and the rod bodies are evenly distributed along the axis of the fixing ring. The rod bodies penetrate through another rod body and are inserted into the soil, and the rod bodies are fixedly connected to another rod body through bolts. After removing the bolts, the effective distance between the two fixing rings can be adjusted. The lower fixing ring is arranged on the ground, and the depth of the rod bodies inserted into the soil can be adjusted by the effective distance between the two fixing rings. It should be noted that in practical applications, a shielding object can be wound around the outer side of the rod bodies to achieve effects such as wind blocking and sun shading, and it can be adaptively matched according to the actual plants to be planted. The shielding object can be a net or ecological straws.

[0031] As Figure 4 shown, a plurality of water collection parts 2 are distributed around the support part 1. As Figure 1 , Figure 2 shown, each water collection part 2 includes a first pipe body 21, a second pipe body 22, a water diversion tray 23, an air introduction part 24, a water outlet part 25 and a water diversion net 26. A water storage cavity 210 is arranged at the lower end of the first pipe body 21. The second pipe body 22 is coaxially arranged with the first pipe body 21 and is located inside the first pipe body 21. The upper end of the second pipe body 22 is fixed to the inner wall of the first pipe body 21. The outer wall of the second pipe body 22 and the inner wall of the first pipe body 21 form a water diversion channel 220, and the water diversion channel is communicated with the water storage cavity 210. The water diversion tray 23 is sleeved on the first pipe body 21, and a water diversion cavity is arranged on the water diversion tray 23. The water diversion cavity is communicated with the water diversion channel 220. The air introduction part 24 is communicated with the second pipe body 22 and is used to introduce air into the second pipe body 22. During the process of the air passing through the second pipe body 22, a temperature difference is generated from above the ground to inside the ground. The water vapor in the air is cooled and condensed into small water droplets during the process of passing into the ground, and then flows into the water storage cavity 210 to complete water collection. The water outlet part 25 has a water inlet end and a water outlet end. A water inlet pipe is arranged at the water inlet end, and the water inlet of the water inlet pipe is located in the water storage cavity 210. One side of the water diversion net 26 is fixed to the support part 1, and the other side is fixed to the water diversion tray 23 and is located in the water diversion cavity. The side of the water diversion net 26 located on the support part 1 is higher than the side located on the water diversion tray 23. The water diversion net 26 is used to collect rainwater during rainfall or small water droplets condensed due to the day-night temperature difference on the surface when there is no rainfall.

[0032] The sand fixation belt group 3 has a plurality of liquid dripping ports, and the liquid dripping ports are connected to the water outlet end through a water outlet pipe. The water in the water storage cavity 210 is led to the liquid dripping ports through the water outlet part 25 for discharge.

[0033] The water collection part 2 realizes effective water collection through the air guiding part 24 and the water diversion net 26. Among them, based on the temperature difference between above the ground surface and below the bottom layer, when the air guiding part 24 guides the air from the ground surface to underground, the moisture in the air condenses into water droplets, and then enters the water storage cavity 210 to realize water collection. Since one side of the water diversion net 26 located on the support part 1 is higher than the side located on the water diversion tray 23, it is inclined. During rainfall, the water diversion net 26 serves as a diversion part to guide the rainwater to the water diversion cavity on the water diversion tray 23, and then enters the water storage cavity 210 through the water diversion channel 220 to realize water collection. During the period without rainfall, based on the day-night temperature difference, the surface temperature of the water diversion net 26 at night will be lower than the temperature of the surrounding air. When the early morning temperature reaches the dew point temperature, the water vapor in the air reaches the saturation state and will condense into small water droplets on the surface of the water diversion net 26. In addition, in some use areas with high humidity, there is sufficient water vapor in the air. When these water vapors encounter the water diversion net 26 with a lower temperature, they will condense into water droplets. It should be noted that in this embodiment, the water diversion net 26 is made of polyethylene plastic net. The water collection part 2 can not only collect rainwater during rainfall but also collect the moisture in the air by using the temperature difference based on the dual water collection of the air guiding part 24 and the water diversion net 26.

[0034] The water collection part 2 cooperates with the sand fixation belt group 3 to effectively improve the environment for the planted plants. Specifically, it plays roles such as wind blocking and water supply for the planted soil body. Among them, the water outlet part 25 leads the water in the water storage cavity 210 to the drip orifice of the sand fixation belt group 3 for discharge, realizing precise drip irrigation, reducing water waste, improving the utilization efficiency of water resources, and at the same time better meeting the water requirements of the soil body and plants near the sand fixation belt, providing a good environment for the growth of plants, being beneficial to improving the survival rate of plants, and further playing the role of plants in soil and water conservation and sand fixation. As Figure 4 shown, the water diversion net 26 and the sand fixation belt group 3 have a better wind blocking effect and can cooperate to maintain the humidity of the soil body, thus achieving a good sand fixation effect. And a plurality of water collection parts 2 are arranged around the support part 1, combined with the sand fixation belt group 3 to form a relatively complete sand fixation and water conservation system, further enhancing the ability of sand fixation and water conservation.

[0035] Preferably, as Figure 1 shown, the inclination angle range of the water diversion net 26 is 30° - 60°, and it can be adjusted by adjusting the depth of insertion of the rod body into the soil and the depth of insertion of the first pipe body 21 into the soil. The inclination angle of the water diversion net 26 can ensure that the water droplets attached to the water diversion net 26 can effectively flow into the water diversion cavity under the action of gravity.

[0036] Preferably, as Figure 2 、 Figure 3As shown, the water storage cavity 210 is in an olive-like spherical structure. A funnel 221 is provided at the lower end of the second pipe body 22. A condensation rack 211 is arranged inside the water storage cavity 210, and the condensation rack 211 is located directly below the funnel 221. As Figure 2 As shown, the upper end of the second pipe body 22 and the upper end of the first pipe body 22 are of an integral structure, that is, the outer wall of the upper end of the second pipe body 22 is connected to the inner wall of the upper end of the first pipe body 22. The air guiding member 24 is arranged above the second pipe body 22 and the first pipe body 22 and is communicated with the second pipe body 22. In this embodiment, the condensation rack 211 is made of a metal material. Since the condensation rack 211 is arranged in the water storage cavity 210 and is located below the bottom layer, its temperature is affected by the area below the bottom layer and always remains at a relatively low temperature.

[0037] In actual use, the air guiding member 24 introduces air from the upper end of the second pipe body 22. The air flows through the second pipe body 22 and reaches the water storage cavity 210. The funnel 221 is provided at the lower end of the second pipe body 22, which can effectively increase the diameter of the air outlet end, facilitating the dispersion of air in the water storage cavity 210, and then contacting the condensation rack 211, enabling the moisture in the air to effectively condense on the condensation rack 211.

[0038] The condensation rack 211 can increase the heat exchange area in the water storage cavity 210. When the water vapor in the air contacts the condensation rack 211 with a relatively low temperature, it is more likely to condense into water droplets, thereby increasing the water volume in the water storage cavity 210. This is particularly important in some areas with large day-night temperature differences, enabling the full utilization of water vapor resources in the air and improving the water collection capacity of the device.

[0039] Preferably, as Figure 3 As shown, the condensation rack 211 includes a condensation ring 2111, a support frame 2112, and a cover 2114. The condensation ring 2111 is fixed on the inner wall of the water storage cavity 210. The support frame 2112 is fixed on the inner ring of the condensation ring 2111 and has a support rod 2113. The support rod 2113 is distributed along the axis of the second pipe body 22. The cover 2114 is fixed on the support rod 2113 and is located at the outlet of the funnel 221. The outer wall of the cover 2114 and the inner wall of the funnel 221 form a gas channel.

[0040] The condensation ring 2111 is fixed to the inner wall of the water storage cavity 210, providing a stable installation foundation for the entire condensation rack 211. This installation method enables the condensation ring 2111 to make full use of the space on the inner wall of the water storage cavity 210, increasing the contact area with the air in the cavity, effectively promoting the condensation of water vapor, improving the condensation efficiency, and collecting more moisture for the water storage cavity 210. The support frame 2112 is fixed to the inner ring of the condensation ring 2111 and is provided with support rods 2113 distributed along the axis of the second pipe body 22. This structural design further enhances the stability of the condensation rack 211, ensuring that it will not easily shake or shift within the water storage cavity 210. At the same time, the distribution method of the support rods 2113 can accurately position the cover body 2114 at the outlet of the funnel 221, ensuring the accurate positional relationship between the components of the condensation rack 211 and guaranteeing the normal functioning of the condensation rack 211. The cover body 2114 is fixed to the support rods 2113 and is located at the outlet of the funnel 221. The outer wall of the cover body 2114 and the inner wall of the funnel 221 form a gas passage. This design can, on the one hand, guide the air discharged from the second pipe body 22 through the funnel 221 to flow within the gas passage, enabling the air to come into full contact with the cover body 2114 and using the relatively low temperature of the cover body 2114 to promote the condensation of water vapor in the air. On the other hand, the cover body 2114 effectively blocks the outlet of the funnel 221, effectively prompting the air to be discharged from the water diversion channel 220 after condensation, avoiding the influence of air accumulation on gas exchange and water flow transmission within the second pipe body 22, maintaining the coherence and stability of the entire device's operation, and ensuring the efficient operation of the water collection and transmission system.

[0041] Preferably, as Figure 3 shown, fin groups 212 are provided on the first pipe body 21, and the fin groups 212 are close to the connection between the first pipe body 21 and the water storage cavity 210; the fin groups 212 include a plurality of annular sheets 2120 distributed in sequence along the length of the first pipe body 21. The annular sheets 2120 are embedded in the first pipe body 21, and the inner ring diameter of the annular sheets 2120 is larger than the pipe diameter of the second pipe body 22.

[0042] The fin groups 212 effectively block the effective path of the water diversion channel 220. On the one hand, the fin groups 212 further perform heat exchange on the air discharged from the water diversion channel 220, avoiding poor condensation effect due to excessive air flow rate and untimely heat exchange. On the other hand, since the water diversion channel essentially introduces the water collected by the water diversion network 26 into the water storage cavity 210, the inner ring diameter of the annular sheets 2120 is larger than the pipe diameter of the second pipe body 22. This design forms a stepped structure within the first pipe body 21. When the water in the water diversion channel 220 flows down, the annular sheets 2120 can buffer and guide the water flow, enabling the water flow to enter the water storage cavity 210 more smoothly, avoiding splashing of water in the water storage cavity due to water flow impact, reducing water loss, and having the effect of optimizing the water flow direction.

[0043] Preferably, the water collecting part 2 further includes a driving member 27, which is connected to the air guiding member 24 and the water outlet member 25, and the driving member 27 is used to convert wind energy into mechanical energy to drive the air guiding member 24 and the water outlet member 25. As Figure 2 shown, the air guiding member 24 includes a housing and a fan rotatably arranged inside the housing. The housing is arranged at the upper ends of the first pipe body 21 and the second pipe body 22, and the housing is communicated with the upper end of the second pipe body 22. An air inlet is provided on the housing. The driving member 27 adopts a commercially available wind turbine blade, and the driving member 27 is rotatably arranged at the upper end of the housing. The driving member 27 is connected to the fan through a transmission member, and the rotation of the wind turbine blade drives the fan to rotate. The water outlet member 25 adopts a commercially available pressing type water pump, and the driving member 27 is connected to the water outlet member 25 through a reciprocating linear mechanism. The driving member 27 is connected to the input end of the reciprocating linear mechanism to drive the reciprocating linear mechanism to rotate, and the output end of the reciprocating linear mechanism is connected to the water outlet member 25 to drive the water outlet member 25 to perform a reciprocating linear motion.

[0044] Preferably, as Figure 1 , Figure 4 shown, there are 3 water collecting parts 2, and the sand fixation belt group 3 is wound around the water collecting parts 2 to form an equilateral triangle with the water collecting parts 2.

[0045] Preferably, the sand fixation belt group 3 includes a plurality of sand fixation belts 30. Each sand fixation belt 30 is correspondingly distributed between two adjacent water collecting parts 2. Both ends of the sand fixation belt 30 are respectively fixed on two adjacent pipe bodies 21. A water guiding channel is arranged in the sand fixation belt 30 along the belt length direction. A liquid dropping port is arranged on the sand fixation belt 30, and the liquid dropping port is communicated with the water outlet pipe through the water guiding channel.

[0046] A plurality of sand fixation belts 30 are correspondingly distributed between two adjacent water collection parts 2 one by one, making full use of the space around the water collection part 2 to form a tight and uniform protection network. This layout enables the water collected by the water collection part 2 to be quickly and efficiently transported to each drip orifice through the water outlet pipe and the water diversion channel in the sand fixation belt 30, ensuring that the soil around the sand fixation belt 30 can obtain water replenishment in a timely manner and realizing the coordinated operation of the water collection and sand fixation functions. Moreover, both ends of the sand fixation belt 30 are respectively fixed on two adjacent first pipe bodies 21, providing a stable support point for the sand fixation belt 30. This not only enables the sand fixation belt 30 to be firmly fixed on the sandy land, effectively resisting the erosion and pulling of wind and sand and being not prone to displacement or fracture, but also enhances the structural integrity of the entire device by connecting multiple water collection parts 2, improving the stability and reliability of the device in a complex wind and sand environment. The combined use of a plurality of sand fixation belts 30 greatly expands the sand fixation and protection area. The adjacent sand fixation belts 30 cooperate with each other to form a continuous sand fixation barrier, which can effectively prevent the movement of wind and sand and fix the sandy soil. At the same time, the drip orifices continuously supply water to the soil around the sand fixation belt 30, helping to maintain the soil humidity, promoting the growth of sand fixation plants, further enhancing the sand fixation effect, and gradually improving the sandy land ecological environment.

[0047] Preferably, an ecological wall is provided on the sand fixation belt 30, and the ecological wall includes ecological straws distributed along the belt length direction of the sand fixation belt 30. The ecological straws are distributed along the belt length direction of the sand fixation belt 30 to form an ecological wall, and their staggered structure can effectively reduce the flow velocity of wind and sand and intercept sand dust particles. The physical blocking effect of the straw itself can directly weaken the erosion force of wind and sand on the soil surface and reduce the wind erosion phenomenon. It is like a natural windbreak wall, forming the first line of defense on the wind and sand flow path and stabilizing the surface structure of the sandy land. The ecological straws will gradually decompose in the natural environment and release nutrients such as organic matter and humus into the soil. These components can improve the poor soil structure of the sandy land, increase the soil porosity, enhance the water and fertilizer retention capacity of the soil, create a more favorable environment for the growth of the roots of sand fixation plants, promote the rooting of plants, and form a virtuous cycle of "straw sand fixation - plant growth - root soil fixation". The ecological straws are widely available and are the residues of agricultural production. Using them to construct the ecological wall of the sand fixation belt 30 realizes the reuse of resources and greatly reduces the material cost of the sand fixation project. At the same time, the straw can be naturally degraded and will not cause secondary pollution to the environment, which conforms to the concept of sustainable development. Even if there is loss in the later stage, it can be conveniently replenished and updated to maintain the long-term effectiveness of the sand fixation system. The ecological straws have a certain water absorption capacity and can absorb and store part of the water discharged from the drip orifices, reducing the rapid evaporation and infiltration loss of water. During the dry period, the water stored in the straws is slowly released, continuously supplying water to the surrounding soil and plants, playing a role similar to a "miniature water storage part" and further enhancing the water retention performance of the sand fixation belt 30.

[0048] Preferably, a through groove 300 is provided along the length direction of the upper edge of the sand-fixing belt 30. A traction rope 301 is arranged in the through groove 300, and a plurality of restraint rings 302 are evenly distributed on the traction rope. After the ecological straws are bundled into bundles, they are inserted into the restraint rings 302, and the lower ends of the ecological straws are inserted into the soil body. The traction rope 301 in the through groove 300 cooperates with the evenly distributed restraint rings 302 to provide a firm fixing structure for the ecological straws. The ecological straws are bundled and inserted into the restraint rings 302, and the lower ends are inserted into the soil body to form double-layer fixation from top to bottom. This design makes the ecological straws not easily blown down or pulled out in the sandy environment, effectively resists the impact of sand and wind, ensures the long-term stability of the ecological wall, and continuously plays the role of sand fixation. By fixing the ecological straws through the restraint rings 302, the installation process is simple and convenient, without the need for complex tools and technologies, and the ecological wall can be quickly built. When the ecological straws need to be replaced due to natural degradation or external damage, only the old straws need to be taken out of the restraint rings 302 and new straw bundles are inserted, which greatly reduces the maintenance difficulty and cost and is convenient for the long-term management and continuous promotion of the sand-fixing project. The restraint rings 302 are evenly distributed along the traction rope 301, ensuring the uniform arrangement of the ecological straws on the sand-fixing belt 30. This uniform distribution makes the blocking effect of the ecological wall on sand and wind more balanced, avoids the emergence of weak protection points, and is also conducive to the uniform diffusion of water between the ecological straws, promotes the uniform distribution of soil humidity, and creates a more stable environment for the growth of sand-fixing plants. The traction rope 301 can be adjusted in position or tightened in the through groove 300 according to actual needs, thereby changing the position and density of the restraint rings 302. In areas with different sand and wind intensities, the number of ecological straws can be flexibly increased or decreased to adjust the protection intensity of the ecological wall; in sections with different plant growth conditions, the space for plant growth can also be reserved by adjusting the restraint rings 302, improving the adaptability of the sand-fixing device to complex environments. The existence of the traction rope 301 and the restraint rings 302 not only enhances the structural stability but also does not hinder the natural degradation process of the ecological straws. When the ecological straws decompose in the restraint rings 302, their nutrients can still be effectively incorporated into the soil. If the materials of the restraint rings 302 and the traction rope 301 are made of environmentally friendly degradable materials, they can participate in the ecological cycle together with the ecological straws, realizing the organic unity of structural functions and ecological benefits.

[0049] A sand-fixing and water-retaining method for soil and water conservation uses the sand-fixing and water-retaining device proposed in this embodiment for sand-fixing and water-retaining, and specifically includes the following steps: Plant plants in the planting cavity.

[0050] When it rains, rainwater is led into the water diversion cavity through the water diversion network 26, and flows into the water storage cavity 210 through the water diversion channel 220 to complete water collection. When it does not rain, the water diversion network 26 collects the small water droplets condensed on its surface, leads them into the water diversion cavity, and flows into the water storage cavity 210 through the water diversion channel 220 to complete water collection; moreover, the air guiding member 24 introduces air into the second pipe body 22. During the process of the air passing through the second pipe body 22, a temperature difference is generated from above the ground into the ground. The water vapor in the air cools and condenses into small water droplets during the process of passing into the ground, and then flows into the water storage cavity 210 to complete water collection. The water in the water storage cavity 210 is led to the drip port through the water outlet member 25 and discharged into the soil around the plants.

[0051] The sand fixation belt group 3 and the water diversion network 26 are both used for wind prevention and sand fixation.

[0052] It should be noted that: as Figure 6 shown, in actual use, multiple groups of the sand fixation and water conservation devices are used in combination. Adjacent sand fixation and water conservation devices can share the edge, that is, the water collection part 2 and the sand fixation belt group 3 in the sides of the polygon can be shared.

[0053] Embodiment 2 Different from Embodiment 2: as Figure 7 shown, there are 4 water collection parts 2, and the sand fixation belt group 3 is wound around the water collection part 2, forming a regular quadrilateral with the water collection part 2.

[0054] Embodiment 3 Different from Embodiment 1: as Figure 8 shown, there are 6 water collection parts 2, and the sand fixation belt group 3 is wound around the water collection part 2, forming a regular hexagon with the water collection part 2.

It should be understood that the above are only specific embodiments of the present invention and do not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are included within the protection scope of the present invention.
