Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of water conservation and sand fixation equipment, and particularly relates to a sand fixation and water conservation device and method for water and soil conservation. BACKGROUND

[0002] The existing sand fixation and water conservation equipment cannot effectively and continuously collect rainwater to achieve water conservation measures. In actual application, artificial interference needs to be carried out in the non-rainy season to take relevant measures to realize artificial water supply for plants in the non-rainy season. Therefore, a large number of transportation tools and manpower are needed, and a large amount of water resources is also wasted in the transportation process, resulting in high water supply cost and difficulty in long-term maintenance of large-scale plant planting.

[0003] 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 the outer side wall is provided with a water collecting groove to facilitate the collection of rainwater. The collected water can directly enter the desert surface layer through the water conservation layer. However, the device cannot effectively and continuously collect rainwater in the desert area. This is mainly because the precipitation in the desert area is low, and the precipitation time is relatively concentrated, and it is not evenly distributed throughout the year. Therefore, the device cannot provide water in the non-rainy season. Moreover, the device cannot provide water for plants in the non-rainy season because it has not collected rainwater. Therefore, artificial water supply is needed for plants, which results in high water supply cost. For another example, the Chinese invention patent with the publication number CN118923389B discloses a sand fixation and water conservation device and method for desert windbreak and sand fixation forest. The device uses a collecting assembly to guide rainwater to the sand in the conical inner frame when it rains, and increases the water collecting area to enable the rainwater to enter the water storage unit for storage. However, the device cannot effectively and continuously collect rainwater in the desert area. Moreover, the device can be supplemented with water from the outside to the water storage unit to realize artificial interference, which results in high water supply cost and difficulty in long-term maintenance of large-scale plant planting. SUMMARY

[0004] In view of the above problems, the purpose of the present application is to provide a sand fixation and water conservation device and method for water and soil conservation, which can realize the sand fixation and water conservation function in the non-rainy season without being restricted by rainfall.

[0005] The technical solution of the present application is a sand fixation and water conservation device for water and soil conservation, which comprises a support part, a plurality of water collecting parts, and a sand fixation belt group.

[0006] The bottom of the support part is used for being inserted into the soil body, and the support part forms a planting cavity on the soil body. The planting cavity is used for planting plants.

[0007] The plurality of water collecting parts are arranged around the support part, and each water collecting part comprises a first pipe body, a second pipe body, a water guide disc, an air guide member, a water outlet member and a water guide net. The lower end of the first pipe body is provided with a water storage cavity, the second pipe body is coaxially arranged with the first pipe body and located in 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 guide channel, and the water guide channel is communicated with the water storage cavity. The water guide disc is sleeved on the first pipe body, the water guide disc is provided with a water guide cavity, the water guide cavity is communicated with the water guide channel, the air guide member is communicated with the second pipe body and used for guiding air into the second pipe body, and the water outlet member has a water inlet end and a water outlet end. The water inlet end is provided with a water inlet pipe, and the water inlet of the water inlet pipe is located in the water storage cavity. One side of the water guide net is fixed to the support part, the other side is fixed to the water guide disc and located in the water guide cavity, and the side of the water guide net located on the support part is higher than the side of the water guide net located on the water guide disc.

[0008] The sand fixation belt set has a plurality of drip outlets, the drip outlets are connected with the water outlet ends through the water outlet pipes, and the water outlet member is used for guiding the water in the water storage cavity to the drip outlets for discharge.

[0009] The water collecting part realizes effective water collection through the air guide member and the water guide net. The air guide member is based on the temperature difference between the ground surface and the bottom layer, and the process of guiding air from the ground surface to the underground causes the water in the air to condense into water droplets, which then enter the water storage cavity to realize water collection. The water guide net is inclined because the side of the water guide net located on the support part is higher than the side of the water guide net located on the water guide disc. The water guide net acts as a flow guide member during rainfall, guiding rainwater into the water guide cavity on the water guide disc, and then into the water storage cavity through the water guide channel to realize water collection. During the non-rainfall period, based on the temperature difference between day and night, the surface temperature of the water guide net is lower than the temperature of the surrounding air at night. When the temperature reaches the dew point in the morning, the air in the air reaches the saturation state, and small water droplets are condensed on the surface of the water guide net. In addition, the humidity in some use areas is relatively high, and the air provides sufficient water vapor. When the water vapor encounters the water guide net with lower temperature, it condenses into water droplets.

[0010] The water collecting part and the sand fixation belt set can effectively improve the environment for planting plants, specifically, wind blocking, water supply for planting soil and the like. The water outlet member guides the water in the water storage cavity to the drip outlets of the sand fixation belt set for discharge, realizes precise drip irrigation, reduces water waste, improves the utilization efficiency of water resources, and better meets the water demand of the soil and plants near the sand fixation belt, provides a good environment for the growth of plants, is conducive to improving the survival rate of plants, and further plays a role of plants in water and soil conservation and sand fixation. The water guide net and the sand fixation belt set have a good wind blocking effect, can cooperate to maintain the humidity of the soil, and thus achieve a good sand fixation effect. The plurality of water collecting parts are arranged around the support part, and form a relatively complete sand fixation and water conservation system in combination with the sand fixation belt set, which further enhances the sand fixation and water conservation capacity.

[0011] Further, the water storage cavity is in the shape of a rugby ball, the lower end of the second tube body is provided with a funnel, and the inside of the water storage cavity is provided with a condensation frame, which is located directly below the funnel. In actual use, the air induction member induces air from the upper end of the second tube body, the air flows through the second tube body to the water storage cavity, and the lower end of the second tube body is provided with a funnel to effectively increase the diameter of the air outlet end, which is conducive to the dispersion of air in the water storage cavity, and then contacts the condensation frame, so that the water in the air can be effectively condensed on the condensation frame.

[0012] Further, the condensation frame comprises a condensation ring, a support frame and a cover. 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 distributed along the tube axis of the second tube body, and the cover is fixed on the support rod and located at the outlet of the funnel, and the outer wall of the cover and the inner wall of the funnel form a gas passage. The cover is fixed on the support rod and located at the outlet of the funnel, and the outer wall of the cover and the inner wall of the funnel form a gas passage. This design can guide the air discharged from the funnel of the second tube body to flow in the gas passage, so that the air fully contacts the cover, and the lower temperature of the cover promotes the condensation of water vapor in the air. On the other hand, the cover effectively blocks the outlet of the funnel, which can effectively promote the air to be discharged from the water induction passage after condensation, avoid the accumulation of air affecting the gas exchange and water flow transmission in the second tube body, maintain the continuity and stability of the whole device, and ensure the efficient operation of the water collection and transmission system.

[0013] Further, the first tube body is provided with a fin group near the connection between the first tube body and the water storage cavity; the fin group comprises a plurality of annular fins distributed along the tube length of the first tube body, the annular fins are embedded on the first tube body, and the inner ring diameter of the annular fin is larger than the tube diameter of the second tube body. The fin group effectively blocks the effective path of the water induction passage, which on the one hand further exchanges heat with the air discharged from the water induction passage, avoiding the air flow rate being too large to cause heat exchange not in time and poor water condensation effect. On the other hand, since the water induction passage is essentially to introduce the water collected by the water induction net into the water storage cavity, the inner ring diameter of the annular fin is larger than the tube diameter of the second tube body. This design forms a stepped structure in the first tube body, which can buffer and guide the water flow when the water flows in the water induction passage, so that the water flow enters the water storage cavity more smoothly, avoids water splashing in the water storage cavity due to water impact, reduces water loss, and has the function of optimizing water flow guidance.

[0014] Further, the water collecting part further comprises a driving member connected with the air induction member and the water outlet member, and the driving member is used to convert wind energy into mechanical energy to drive the air induction member and the water outlet member.

[0015] Further, the water collecting part has 3-6, and the sand fixing belt group is arranged on the water collecting part to form a regular polygon with the water collecting part.

[0016] Further, the sand-fixing belt set comprises a plurality of sand-fixing belts, each of which is distributed one-to-one between two adjacent water collecting parts, and the two ends of the sand-fixing belt are fixed on the adjacent two pipe bodies respectively, a water diversion channel is arranged in the sand-fixing belt and is distributed along the length direction of the belt, and the drip outlet is arranged on the sand-fixing belt and is communicated with the water outlet pipe through the water diversion channel. The plurality of sand-fixing belts are distributed one-to-one between two adjacent water collecting parts, the space around the water collecting part is fully utilized, a close and uniform protection network is formed, this layout mode enables the water collected by the water collecting part to be quickly and efficiently transported to each drip outlet through the water outlet pipe and the water diversion channel in the sand-fixing belt, so that the soil around the sand-fixing belt can obtain water supply in time, and the functions of water collecting and sand fixing are cooperatively operated. Further, the two ends of the sand-fixing belt are fixed on the adjacent two first pipe bodies respectively, which provides stable support points for the sand-fixing belt, which not only enables the sand-fixing belt to be firmly fixed on the sandy land and effectively resist the erosion and pulling of wind sand, and is not prone to displacement or breakage, but also connects a plurality of water collecting parts, enhances the structural integrity of the whole device, and improves the stability and reliability of the device in a complex wind-sand environment. The combined use of a plurality of sand-fixing belts greatly expands the area of sand-fixing protection, the adjacent sand-fixing belts cooperate with each other to form a continuous sand-fixing barrier, which can effectively prevent the movement of wind sand and fix the sandy land soil. At the same time, the drip outlet continuously supplies water to the soil around the sand-fixing belt, which helps to maintain the soil humidity, promotes the growth of sand-fixing plants, further enhances the sand-fixing effect, and gradually improves the ecological environment of the sandy land.

[0017] Further, the sand-fixing belt is provided with an ecological wall body, which includes ecological straws distributed along the length direction of the sand-fixing belt. The ecological straws form the ecological wall body along the length direction of the sand-fixing belt, and the staggered structure of the ecological wall body can effectively reduce the wind-sand flow rate and trap sand and dust particles. The physical blocking effect of the straws can directly weaken the erosion of the wind-sand on the soil surface and reduce the wind erosion phenomenon. The ecological straws can form the first line of defense on the wind-sand flow path, like a natural windbreak, and stabilize the surface layer structure of the sand. The ecological straws can 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 sand, increase the soil porosity, and improve the water and fertilizer retention capacity of the soil, so as to create a more favorable environment for the growth of the root system of the sand-fixing plants, promote the plant rooting, and form a virtuous cycle of "straw sand-fixing-plant growth-root soil fixation". The ecological straws are widely available and belong to the surplus of agricultural production. The use of the ecological straws for the construction of the ecological wall body of the sand-fixing belt can realize the reuse of resources and greatly reduce the material cost of the sand-fixing project. At the same time, the straws can be naturally degraded and will not cause secondary pollution to the environment, which is in line with the concept of sustainable development. Even if the straws are lost later, they can be conveniently supplemented and updated, so as to maintain the long-term effectiveness of the sand-fixing system. The ecological straws have a certain water absorption capacity and can absorb and store part of the water discharged from the drip irrigation holes, so as to reduce the rapid evaporation and downward infiltration loss of the water. In the dry period, the water stored in the straws is slowly released to continuously supplement the surrounding soil and plants, which plays a role similar to a "micro water storage part" and further improves the water retention performance of the sand-fixing belt.

[0018] Further, the sand-fixing belt is provided with a through groove along the length direction of the belt, and a traction rope is arranged in the through groove, and a plurality of constraint rings are uniformly distributed on the traction rope, and the ecological straws are inserted into the constraint rings after being bundled, and the lower ends of the ecological straws are inserted into the soil. This design makes the ecological straws not easy to be blown down or pulled out in the wind-sand environment, effectively resists the impact of wind and sand, ensures the long-term stability of the ecological wall, and continuously plays the sand-fixing role. The ecological straws are fixed by the constraint rings, the installation process is simple and convenient, and complex tools and technologies are not needed, so that the ecological wall can be quickly built. When the ecological straws need to be replaced due to natural degradation or external damage, the old straws can be taken out of the constraint rings, and new straw bundles can be inserted, so that the maintenance difficulty and cost are greatly reduced, and the long-term management and continuous promotion of the sand-fixing project are facilitated. The constraint rings are uniformly distributed along the traction rope, so that the uniform arrangement of the ecological straws on the sand-fixing belt is ensured. The uniform distribution makes the ecological wall have more balanced resistance to wind and sand, avoids the weak points of protection, and is also beneficial to the uniform diffusion of water between the ecological straws, promotes the balanced distribution of soil humidity, and creates a more stable environment for the growth of sand-fixing plants. The position of the traction rope can be adjusted or the tightness can be adjusted in the through groove according to actual needs, so that the position and density of the constraint rings are changed, the number of ecological straws can be flexibly increased or reduced in areas with different wind and sand intensities, and the protection strength of the ecological wall can be adjusted; in sections with different plant growth conditions, the constraint rings can also be adjusted to reserve space for plant growth, and the adaptability of the sand-fixing device to complex environments is improved. The existence of the traction rope and the constraint ring 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 constraint rings, the nutrients can still be effectively absorbed into the soil, and if the materials of the constraint rings and the traction rope are environmentally friendly and degradable, they can participate in ecological circulation together with the ecological straws, realize the organic unity of structure and function and ecological benefits.

[0019] A sand-fixing and water-retaining method for soil and water conservation, which utilizes the sand-fixing and water-retaining device to fix sand and retain water, specifically includes the following steps:

[0020] Plants are planted in the planting cavity.

[0021] When it rains, rainwater is introduced into the water introduction cavity through the water introduction net, flows into the water storage cavity through the water introduction channel to complete water collection. When it does not rain, the water introduction net collects small water droplets condensed on its surface, introduces them into the water introduction cavity, and then flows into the water storage cavity through the water introduction channel to complete water collection. In addition, the air introduction member introduces air into the second pipe body, and the temperature difference between the air above the ground and the ground is generated during the process of the air passing through the second pipe body, so that the water vapor in the air cools and condenses into small water droplets during the process of the air passing into the ground, and then flows into the water storage cavity to complete water collection. The water in the water storage cavity is introduced to the drip outlet through the water outlet member, and is discharged into the soil around the plants.

[0022] The sand-fixing belt group and the water introduction net are used for wind prevention and sand fixation.

[0023] Compared with the prior art, the application has the beneficial effects that: the water collecting part of the application can effectively collect the surrounding moisture through the air inlet part and the water inlet net of the water collecting part, and store it in the water storage cavity at the lower end of the first pipe body, thereby providing guarantee for subsequent water supply and adapting to drought and water shortage environment. The air inlet part is based on the temperature difference between the surface and the bottom layer, and the process of introducing air from the surface to the underground, so that the moisture in the air condenses into water droplets, and then enters the water storage cavity to realize water collection. The water inlet net is used to collect rainwater when it rains or small water droplets condensed on its surface due to the temperature difference between day and night when it does not rain, and then enters the water storage cavity through the water inlet channel to realize water collection. The water outlet part introduces the water in the water storage cavity to the liquid outlet of the sand fixation belt group for discharge, realizes precise drip irrigation, reduces water waste, improves the utilization efficiency of water resources, and at the same time can better meet the demand of the soil and plants near the sand fixation belt for water, provides a good environment for the growth of plants, is conducive to improving the survival rate of plants, and then plays a role in water and soil conservation and sand fixation. The water inlet net and the sand fixation belt group have good wind resistance, can cooperate to maintain the humidity of the soil, thereby achieving good sand fixation effect. And a plurality of water collecting parts are arranged around the support part, and a relatively complete sand fixation and water conservation system is formed in combination with the sand fixation belt group, thereby further enhancing the sand fixation and water conservation capacity.

[0036] Example 1

[0037] like Figure 1 The device shown is a soil and water conservation sand fixation and water retention device, including a support part 1, multiple water collection parts 2 and sand fixation belt group 3.

[0038] The bottom of the support part 1 is used for being inserted into the soil, and the support part 1 forms a planting cavity on the soil, and the planting cavity is used for planting plants. In this embodiment, the support part 1 comprises a plurality of rod bodies and two fixing rings, the top ends of the plurality of rod bodies are rotationally arranged on one of the fixing rings, the rod bodies are uniformly distributed along the axis of the fixing ring, the rod bodies penetrate through the other rod bodies and are inserted into the soil, and the rod bodies are fixedly connected to the other rod bodies through bolts, and the effective distance between the two fixing rings can be adjusted after the bolts are removed. The lower fixing ring is arranged on the ground, and the effective distance between the two fixing rings can be adjusted to adjust the depth of the rod bodies inserted into the soil. It should be noted that, in actual application, a shielding object can be wound around the outer side of the rod body to achieve wind blocking, sun shading and the like, and the shielding object can be a net or ecological straw, which is adaptively matched according to the actual planting plants.

[0039] As shown in Figure 4 , a plurality of water collecting parts 2 are distributed around the support part 1, as shown in Figure 1 , Figure 2 , each water collecting part 2 comprises a first pipe body 21, a second pipe body 22, a water guide disc 23, an air guide member 24, a water outlet member 25 and a water guide net 26. The lower end of the first pipe body 21 is provided with a water storage cavity 210, the second pipe body 22 is coaxially arranged with the first pipe body 21 and located in 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 guide channel 220, and the water guide channel is communicated with the water storage cavity 210. The water guide disc 23 is sleeved on the first pipe body 21, the water guide disc 23 is provided with a water guide cavity, the water guide cavity is communicated with the water guide channel 220; the air guide member 24 is communicated with the second pipe body 22 and used for guiding air into the second pipe body 22, the air enters the ground from above the ground during the process of passing through the second pipe body 22 to generate temperature difference, 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 outlet member 25 has a water inlet end and a water outlet end, the water inlet end is provided with a water inlet pipe, and the water inlet of the water inlet pipe is located in the water storage cavity 210. One side of the water guide net 26 is fixed to the support part 1, the other side is fixed to the water guide disc 23 and located in the water guide cavity, the side of the water guide net 26 located on the support part 1 is higher than the side located on the water guide disc 23, and the water guide net 26 is used for collecting rainwater during rainfall or collecting small water droplets condensed on the surface due to temperature difference between day and night during non-rainfall.

[0040] The sand fixation belt group 3 has a plurality of drip outlets, the drip outlets are connected with the water outlet ends through water outlet pipes, and the water in the water storage cavity 210 is guided to the drip outlets through the water outlet member 25 for discharge.

[0041] The water collecting part 2 realizes effective water collection through the air guiding part 24 and the water guiding net 26. The air guiding part 24 is based on the temperature difference between the surface and the bottom layer. During the process of guiding air from the surface to the underground, the water in the air condenses into water droplets, and then enters the water storage cavity 210 to realize water collection. The water guiding net 26 is inclined on one side of the support part 1, which is higher than the other side on the water guiding disc 23. The water guiding net 26 acts as a flow guide during rainfall, guiding rainwater into the water guiding cavity on the water guiding disc 23, and then through the water guiding channel 220 into the water storage cavity 210 to realize water collection. During the non-rainfall period, based on the temperature difference between day and night, the surface temperature of the water guiding net 26 is lower than the temperature of the surrounding air. When the temperature reaches the dew point in the morning, the air humidity reaches saturation, and the water droplets condense on the surface of the water guiding net 26. In addition, some areas have high humidity, and the air provides sufficient water vapor. When the water vapor encounters the water guiding net 26 with lower temperature, it condenses into water droplets. It should be noted that the water guiding net 26 in this embodiment is made of polyethylene plastic net. The water collecting part 2 based on the double water collection of the air guiding part 24 and the water guiding net 26 can not only collect rainwater during rainfall, but also collect water in the air based on the temperature difference.

[0042] The water collecting part 2 cooperates with the sand fixation belt group 3 to effectively improve the environment for planting plants, specifically for wind blocking, water supply for planting soil, and other improvement effects. The water outlet 25 guides the water in the water storage cavity 210 to the drip port of the sand fixation belt group 3 for discharge, realizing precise drip irrigation, reducing water waste, improving water resource utilization efficiency, and better meeting the water demand of the soil and plants near the sand fixation belt, providing a good environment for plant growth, which is conducive to improving the survival rate of plants, and further playing the role of plants in water and soil conservation and sand fixation. As shown in Figure 4 The water guiding net 26 and the sand fixation belt group 3 have good wind resistance, which can cooperate to maintain the humidity of the soil, thereby achieving good sand fixation effect. And multiple water collecting 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 sand fixation and water conservation capacity.

[0043] Preferably, as shown in Figure 1 The inclination angle of the water guiding net 26 is 30°-60°, which can be adjusted by adjusting the depth of the rod body inserted into the soil and the depth of the first pipe body 21 inserted into the soil. The inclination angle of the water guiding net 26 can ensure that the water droplets attached to the water guiding net 26 can effectively flow into the water guiding cavity under the action of gravity.

[0044] Preferably, as shown in Figure 2 , Figure 3As shown, the water storage cavity 210 is in the shape of a rugby ball, and the lower end of the second tube body 22 is provided with a funnel 221. Inside the water storage cavity 210 is provided with a condensing frame 211, which is located directly below the funnel 221. Figure 2 As shown, the upper end of the second tube body 22 is in an integrated structure with the upper end of the first tube body 22, that is, the outer wall of the upper end of the second tube body 22 is connected with the inner wall of the upper end of the first tube body 22, and the air guide member 24 is arranged above the second tube body 22 and the first tube body 22 and communicates with the second tube body 22. The condensing frame 211 of this embodiment is made of metal. Since the condensing frame 211 is arranged inside the water storage cavity 210 and below the bottom layer, its temperature is affected by the area below the bottom layer and always maintains a relatively low temperature.

[0045] In actual use, the air guide member 24 introduces air from the upper end of the second tube body 22, and the air flows through the second tube body 22 to the water storage cavity 210. The lower end of the second tube body 22 is provided with a funnel 221, which can effectively increase the pipe diameter of the air outlet and is beneficial to the dispersion of air in the water storage cavity 210, thereby contacting the condensing frame 211 and enabling the moisture in the air to be effectively condensed on the condensing frame 211.

[0046] The condensing frame 211 can increase the heat exchange area in the water storage cavity 210. The water vapor in the air is more likely to condense into water droplets when it contacts the condensing frame 211 with a relatively low temperature, thereby increasing the water amount in the water storage cavity 210. This is particularly important in some areas with large diurnal temperature differences, which can fully utilize the water vapor resources in the air and improve the water collection capacity of the device.

[0047] Preferably, as shown, Figure 3 As shown, the condensing frame 211 includes a condensing ring 2111, a support frame 2112, and a cover body 2114. The condensing ring 2111 is fixed to the inner wall of the water storage cavity 210, the support frame 2112 is fixed to the inner ring of the condensing ring 2111 and has a support rod 2113 distributed along the tube axis of the second tube body 22, and the cover body 2114 is fixed to the support rod 2113 and 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.

[0048] The condensing ring 2111 is fixed on the inner wall of the water storage cavity 210, providing a stable installation basis for the entire condensing frame 211. This installation method can make full use of the space of the inner wall of the water storage cavity 210, increase the contact area with the air in the cavity, effectively promote the condensation of water vapor, improve the condensation efficiency, and collect more moisture for the water storage cavity 210. The support frame 2112 is fixed on the inner ring of the condensing ring 2111 and is provided with support rods 2113 distributed along the pipe axis of the second pipe body 22. This structure design further enhances the stability of the condensing frame 211, ensuring that it cannot easily shake or shift in the water storage cavity 210. At the same time, the distribution 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 condensing frame 211 and ensuring the normal functioning of the condensing frame 211. The cover body 2114 is fixed on the support rods 2113 and located at the outlet of the funnel 221, and its outer wall forms a gas passage with the inner wall of the funnel 221. This design can guide the air discharged from the second pipe body 22 to flow in the gas passage, making the air fully contact with the cover body 2114 and promoting the condensation of water vapor in the air by utilizing the lower temperature of the cover body 2114. On the other hand, the cover body 2114 effectively blocks the outlet of the funnel 221, which can effectively promote the air to be discharged from the water guide channel 220 after condensation, avoiding the accumulation of air affecting the gas exchange and water flow transmission in the second pipe body 22, maintaining the coherence and stability of the entire device operation, and ensuring the efficient operation of the moisture collection and transmission system.

[0049] Preferably, as shown in the drawings, the first pipe body 21 is provided with a fin group 212, which is close to the connection between the first pipe body 21 and the water storage cavity 210. The fin group 212 includes a plurality of annular fins 2120 distributed along the length of the first pipe body 21. The annular fins 2120 are embedded on the first pipe body 21, and the inner diameter of the annular fins 2120 is larger than the pipe diameter of the second pipe body 22. Figure 3

[0050] The fin group 212 effectively blocks the effective path of the water guide channel 220. On the one hand, it further exchanges heat with the air discharged from the water guide channel 220, avoiding the problem of insufficient heat exchange due to excessive air flow speed, and improving the condensation effect of moisture. On the other hand, since the water guide channel is essentially to guide the water collected by the water guide net 26 into the water storage cavity 210, the inner diameter of the annular fin 2120 is larger than the pipe diameter of the second pipe body 22. This design forms a stepped structure in the first pipe body 21, which can buffer and guide the water flow when it flows down in the water guide channel 220, making the water flow more stable into the water storage cavity 210, avoiding the splashing of water in the water storage cavity due to water flow impact, reducing moisture loss, and optimizing water flow guidance.

[0051] ​Preferably, the water collecting part 2 further comprises a driving member 27, the driving member 27 is connected with 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 shown in Figure 2 The air guiding member 24 comprises a shell and a fan rotatingly arranged in the shell, the shell is arranged on the upper end of the first pipe body 21 and the second pipe body 22, and the shell is communicated with the upper end of the second pipe body 22, and the shell is provided with an air inlet. The driving member 27 adopts a commercially available wind fan blade, the driving member 27 is rotatingly arranged on the upper end of the shell, the driving member 27 is connected with the fan through a transmission member, and the wind fan blade drives the fan to rotate. The water outlet member 25 adopts a commercially available press type water pump, the driving member 27 is connected with the water outlet member 25 through a reciprocating linear mechanism, the driving member 27 is connected with 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 with the water outlet member 25 to drive the water outlet member 25 to perform reciprocating linear motion.

[0052] Preferably, as shown in Figure 1 , Figure 4 The water collecting part 2 has three water collecting parts 2, and the sand fixing belt groups 3 are arranged around the water collecting parts 2 to form an equilateral triangle with the water collecting parts 2.

[0053] Preferably, the sand fixing belt group 3 comprises a plurality of sand fixing belts 30, each sand fixing belt 30 is correspondingly arranged between two adjacent water collecting parts 2, the two ends of the sand fixing belt 30 are fixed on the two adjacent pipe bodies 21 respectively, the sand fixing belt 30 is provided with water guiding channels arranged along the length direction of the sand fixing belt 30, and the drip outlets are arranged on the sand fixing belt 30 and communicated with the water outlet pipe through the water guiding channels.

[0054] A plurality of sand-fixing belts 30 are distributed one by one between adjacent two water collecting parts 2, fully utilizing the space around the water collecting part 2, forming a tight and uniform protection network. This layout enables the water collected by the water collecting part 2 to be quickly and efficiently transported to each drip outlet through the water outlet pipe and the water guide channel in the sand-fixing belt 30, ensuring that the soil around the sand-fixing belt 30 can be timely supplied with water, realizing the synergistic operation of the water collecting and sand-fixing functions. Moreover, the two ends of the sand-fixing belt 30 are fixed on the adjacent two first pipe bodies 21, providing stable support points for the sand-fixing belt 30. This not only enables the sand-fixing belt 30 to be firmly fixed on the sand land, effectively resisting the erosion and pulling of wind and sand, and is not prone to displacement or breakage, but also connects a plurality of water collecting parts 2 together, enhancing the structural integrity of the entire device and improving the stability and reliability of the device in complex wind and sand environment. The combined use of a plurality of sand-fixing belts 30 greatly expands the area of sand-fixing protection, and the adjacent sand-fixing belts 30 cooperate with each other to form a continuous sand-fixing barrier, which can effectively prevent the movement of wind and sand and fix the sand land soil. At the same time, the drip outlet continuously supplies water to the soil around the sand-fixing belt 30, which helps to maintain soil humidity, promotes the growth of sand-fixing plants, further enhances the sand-fixing effect, and gradually improves the ecological environment of the sand land.

[0055] Preferably, the sand-fixing belt 30 is provided with an ecological wall body, which includes ecological straws distributed along the length direction of the sand-fixing belt 30. The ecological straws form an ecological wall body along the length direction of the sand-fixing belt 30, and the staggered structure can effectively reduce the wind and sand flow rate and trap sand and dust particles. The physical blocking effect of the straw itself can directly weaken the erosion of wind and sand on the soil surface and reduce wind erosion, like a natural windbreak, forming the first line of defense on the wind and sand flow path and stabilizing the surface structure of the sand land. The ecological straw 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 sand land, increase the soil porosity, and improve the soil water and fertilizer retention capacity, creating a more favorable environment for the growth of sand-fixing plant roots, promoting root growth, and forming a virtuous cycle of "straw sand-fixing-plant growth-root soil fixation". The ecological straw is widely available and belongs to the surplus of agricultural production. Its use in the construction of the ecological wall body of the sand-fixing belt 30 realizes the reuse of resources and greatly reduces the material cost of the sand-fixing project. At the same time, the straw can be naturally degraded and will not cause secondary pollution to the environment, in line with the concept of sustainable development. Even if there is wear and tear later, it can be easily replenished and updated, maintaining the long-term effectiveness of the sand-fixing system. The ecological straw has a certain water absorption capacity and can absorb and store part of the water discharged by the drip outlet, reducing the rapid evaporation and downward flow loss of water. During the dry period, the water stored in the straw is slowly released, continuously supplying water to the surrounding soil and plants, playing a role similar to a "micro water storage part", further improving the water retention performance of the sand-fixing belt 30.

[0056] Preferably, the sand-fixing belt 30 is provided with a through groove 300 along the length direction of the belt, and a traction rope 301 is arranged in the through groove 300. The traction rope is uniformly provided with a plurality of constraint rings 302. The ecological straws are bundled and inserted into the constraint rings 302. The lower ends of the ecological straws are inserted into the soil. The traction rope 301 in the through groove 300 cooperates with the uniformly distributed constraint rings 302 to provide a firm fixing structure for the ecological straws. The ecological straws are inserted into the constraint rings 302 and the lower ends are inserted into the soil, forming a double fixing structure. This design makes the ecological straws not easy to be blown down or pulled out in a windy and sandy environment, effectively resisting the impact of wind and sand, ensuring the long-term stability of the ecological wall and continuously playing a sand-fixing role. By fixing the ecological straws through the constraint rings 302, the installation process is simple and convenient, and complex tools and techniques are not required, and the ecological wall can be quickly built. When the ecological straws need to be replaced due to natural degradation or external damage, the old straws can be taken out from the constraint rings 302 and new straw bundles can be inserted, which greatly reduces the maintenance difficulty and cost and is convenient for long-term management and continuous promotion of the sand-fixing project. The constraint rings 302 are uniformly 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 ecological wall more balanced in blocking wind and sand, avoids weak points in protection, and is also conducive to the uniform diffusion of water between the ecological straws, promoting the balanced distribution of soil humidity and creating a more stable environment for the growth of sand-fixing plants. The position of the traction rope 301 can be adjusted or the tightness can be adjusted in the through groove 300, thereby changing the position and density of the constraint rings 302. In areas with different wind and sand intensities, the number of ecological straws can be flexibly increased or decreased, and the protection strength of the ecological wall can be adjusted. In areas with different plant growth conditions, the constraint rings 302 can also be adjusted to reserve space for plant growth, improving the adaptability of the sand-fixing device to complex environments. The existence of the traction rope 301 and the constraint 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 constraint rings 302, their nutrients can still effectively enter the soil. If the materials of the constraint rings 302 and the traction rope 301 are environmentally friendly and degradable, they can participate in ecological circulation together with the ecological straws, realizing the organic unity of structure and function and ecological benefits.

[0059] When it rains, rainwater is introduced into the water guide cavity through the water guide net 26, flows into the water storage cavity 210 through the water guide channel 220 to complete water collection. When it does not rain, the water guide net 26 collects small water droplets condensed on its surface and introduces them into the water guide cavity, and then flows into the water storage cavity 210 through the water guide channel 220 to complete water collection. In addition, the air guide member 24 introduces air into the second pipe body 22, and the air cools and condenses into small water droplets during the process of entering the ground from above the ground, and then flows into the water storage cavity 210 to complete water collection. The water in the water storage cavity 210 is introduced to the drip port through the water outlet member 25 and discharged into the soil around the plant.

[0060] The sand-fixing belt group 3 and the water guide net 26 are used for wind prevention and sand fixation.

[0061] It should be noted that, as shown in Figure 6 , the sand-fixing water-retaining device is used in cooperation with multiple groups in actual use, and adjacent sand-fixing water-retaining devices can share edges, that is, the water collection part 2 and the sand-fixing belt group 3 in the edges of the polygon can be shared.
