Sand-fixing and water-retaining device and method for soil and water conservation

Abstract

This invention discloses a sand-fixing and water-retention device and method for soil and water conservation, relating to the field of soil and water conservation and sand fixation. The device and method involve inserting and fixing a sand-fixing frame's fixing pipe into the sand, then storing the injected water inside the fixing pipe. A water-guiding rope is used to slowly moisten the surface of the sand. Simultaneously, as the surface moisture evaporates, air enters the first air inlet trough, flows upward under the guidance of the first air inlet inclined plate, carrying water vapor to the other air inlet trough, and then through the ventilation trough and the second air inlet trough into the installation box and fixing pipe. Because the first and second condensation bends are buried underground at low temperatures, the water-laden air is condensed into water by condensing plates within them, and then flows back into the fixing pipe for collection. This process effectively reduces water consumption, allowing the sand within the sand-fixing frame to retain moisture and stabilize, creating favorable conditions for plant growth, enhancing ecological stability, and demonstrating significant advantages in soil and water conservation work in arid and semi-arid regions.

Description

Technical Field

[0001] This invention relates to soil and water conservation and sand fixation technology, specifically to a sand fixation and water conservation device and method for soil and water conservation. Background Technology

[0002] In arid and semi-arid regions, soil erosion and desertification are extremely serious ecological and environmental problems, posing a significant threat to local ecological balance, agricultural production, and residents' lives. While traditional soil and water conservation and sand fixation methods have played a role to some extent, they have many limitations and are insufficient to meet the growing demands for ecological protection.

[0003] Existing sand-fixing technologies mostly rely on physical barriers, such as sand barriers. While these barriers can block wind and sand movement and slow down dune movement, their function is relatively limited, serving only as physical barriers and failing to effectively address the problem of soil moisture retention. In arid environments, soil moisture evaporates very easily, leading to a lack of necessary water for plant growth, making it difficult for plants to take root and grow within the sand barriers, thus affecting the sustainability of sand-fixing effects. Once sand barriers fail due to natural factors or human damage, desertification will rapidly rebound.

[0004] In summary, existing soil and water conservation and sand fixation technologies suffer from limited functionality and poor water retention, making it difficult to achieve efficient and sustainable soil and water conservation and sand fixation goals in arid and semi-arid regions. Therefore, developing a soil and water conservation sand fixation and water conservation device and method with superior comprehensive performance that can effectively solve the above problems is of significant practical importance. Summary of the Invention

[0005] The purpose of this invention is to provide a soil and water conservation device and method for soil and water conservation, so as to solve the problems that existing soil and water conservation and sand fixation technologies have limited functions, poor water retention effect, and difficulty in achieving efficient and sustainable soil and water conservation and sand fixation goals in arid and semi-arid regions.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sand-fixing and water-retaining device for soil and water conservation, comprising a sand-fixing frame, a plurality of mounting boxes fixedly connected to the bottom of the sand-fixing frame, a fixing pipe fixedly connected to the bottom of the mounting boxes, a first air inlet groove opened on the sand-fixing frame, a first air inlet inclined plate fixedly connected in the first air inlet groove, a ventilation groove opened on the sand-fixing frame, a second air inlet groove opened on the mounting boxes communicating with the ventilation groove, a second air inlet inclined plate fixedly connected in the ventilation groove, and a first condensation bend fixedly connected between the two fixing pipes;

[0007] A water outlet pipe is fixedly connected to the fixed pipe, and a water-guiding rope fixedly connected to the water outlet pipe is installed inside the fixed pipe. An air-guiding adjustment mechanism is installed on the sand-fixing frame. The air-guiding adjustment mechanism is used to guide the wind blowing towards the sand-fixing frame and adjust the air volume in the first air inlet slot.

[0008] Furthermore, the air-guiding adjustment mechanism includes a mounting shaft rotatably connected to the sand-fixing frame, an air-guiding plate fixedly connected to the outer surface of the mounting shaft, an adjustment plate slidably connected to the sand-fixing frame, an arc-shaped spring piece fixedly connected to the top of the adjustment plate and fixedly connected to the air-guiding plate, and a spring fixedly connected to the sand-fixing frame via a connecting block on one side of the adjustment plate.

[0009] Furthermore, a second condensing bend is provided below the first condensing bend and is fixedly connected to the fixed pipe, and a plurality of first heat-conducting plates are fixedly connected between the first condensing bend and the second condensing bend.

[0010] Furthermore, multiple second heat-conducting plates are fixedly connected to the bottom of the second condensation bend.

[0011] Furthermore, multiple condenser fins are fixedly connected to the inner surfaces of both the first and second condenser bends.

[0012] Furthermore, a water-receiving groove is provided on the top of the sand-fixing frame, and a water-draining groove is provided inside the water-receiving groove.

[0013] Furthermore, multiple mounting rings are fixedly connected inside the sand-fixing frame, the mounting rings being used to fix the sand-fixing net, and a conical block is fixedly connected to the bottom end of the fixing tube.

[0014] Furthermore, a water inlet pipe is fixedly connected to the top of the sand-fixing frame, the outer surface of the water inlet pipe is fixedly connected to the mounting box, and a sealing block is threadedly connected to the top of the water inlet pipe.

[0015] A method for soil and water conservation to fix sand and retain water includes the following steps:

[0016] Step 1: Insert the fixing pipes on multiple sand-fixing frames into the required soil and water stabilization locations;

[0017] Step 2: Pour water into the fixed pipe through the inlet pipe and bury the water-guiding rope in the surface layer of sand.

[0018] Step 3: Plant the plants inside the sand-fixing frame, and then fix the sand-prevention net to the installation ring inside the sand-fixing frame.

[0019] Compared with the prior art, the sand-fixing and water-retaining device and method for soil and water conservation provided by the present invention have the following beneficial effects:

[0020] After the fixing pipe of the sand-fixing frame is inserted into and secured in the sand, the injected water is stored inside the fixing pipe, and the surface of the sand is slowly moistened using a water-guiding rope. Simultaneously, as surface moisture evaporates, the device cleverly guides the evaporating water vapor. Air enters the first air inlet sluice, flows upward under the guidance of the first air inlet inclined plate, carrying water vapor to the other air inlet sluice, then through the ventilation sluice and the second air inlet sluice into the installation box and fixing pipe. Because the first and second condensation bends are buried underground at low temperatures, the water-laden air is condensed into water by the condensing plates within them, and then flows back into the fixing pipe for collection. This process effectively reduces water consumption, allowing the sand within the sand-fixing frame to retain moisture and stabilize the sand, creating favorable conditions for plant growth, enhancing ecological stability, and demonstrating significant advantages in soil and water conservation work in arid and semi-arid regions.

[0021] When the wind blows, the wind deflector guides the wind upwards, reducing the wind's blowing and drying effects on the sand. When the wind is strong, the wind deflector rotates under the wind force, causing the arc-shaped spring to bend, moving the adjusting plate downwards, compressing the spring, and thus adjusting the gap between the adjusting plate and the first air intake ramp, reducing the air intake gap. This keeps the wind force above the sand within a certain range, preventing excessive wind from accelerating the drying and blowing of the sand surface, further improving the sand-fixing effect. Furthermore, the design of the water collection and drainage channels in Embodiment 2 allows rainwater to be collected and stored in fixed pipes during rainfall, increasing water storage capacity and comprehensively improving the sand-fixing and water-retention effect, providing a reliable guarantee for soil and water conservation work.

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] Please see Figures 1 to 6 As shown, the present invention provides a sand-fixing and water-retaining device for soil and water conservation, including a sand-fixing frame 1. Multiple installation boxes 2 are fixedly connected to the bottom of the sand-fixing frame 1. Fixed pipes 3 are fixedly connected to the bottom of the installation boxes 2. By inserting four fixed pipes 3 into the sand, the installation boxes 2 and the sand-fixing frame 1 can be firmly fixed, effectively preventing the device from being blown away or displaced by the wind in harsh environments, laying a solid foundation for subsequent sand-fixing and water-retaining work. A first air inlet groove 4 is opened on the sand-fixing frame 1. A first air inlet inclined plate 5 is fixedly connected in the first air inlet groove 4. A ventilation groove 6 is opened on the sand-fixing frame 1. A second air inlet groove 7 communicating with the ventilation groove 6 is opened on the installation box 2. A second air inlet inclined plate 8 is fixedly connected in the ventilation groove 6. A first condensation bend 9 is fixedly connected between the two fixed pipes 3.

[0034] A water outlet pipe 10 is fixedly connected to the fixed pipe 3. A water-guiding rope 11, which is fixedly connected to the water outlet pipe 10, is installed inside the fixed pipe 3. An air-guiding adjustment mechanism is installed on the sand-fixing frame 1. The air-guiding adjustment mechanism is used to guide the wind blowing towards the sand-fixing frame 1 and to adjust the air volume in the first air inlet slot 4. Multiple mounting rings 51 are fixedly connected inside the sand-fixing frame 1. The mounting rings 51 are used to fix the sand-fixing net. A conical block is fixedly connected to the bottom end of the fixed pipe 3. A water inlet pipe 61 is fixedly connected to the top of the sand-fixing frame 1. The outer surface of the water inlet pipe 61 is fixedly connected to the mounting box 2. A sealing block 62 is threadedly connected to the top of the water inlet pipe 61.

[0035] The air-guiding adjustment mechanism includes a mounting shaft 21 that is rotatably connected to the sand-fixing frame 1. An air-guiding plate 22 is fixedly connected to the outer surface of the mounting shaft 21. An adjustment plate 23 is slidably connected to the sand-fixing frame 1. An arc-shaped spring piece 24 that is fixedly connected to the air-guiding plate 22 is fixedly connected to the top of the adjustment plate 23. A spring 25 that is fixedly connected to the sand-fixing frame 1 is fixedly connected to one side of the adjustment plate 23 through a connecting block.

[0036] Below the first condensing bend 9, a second condensing bend 31 is fixedly connected to the fixed pipe 3. Multiple first heat-conducting plates 32 are fixedly connected between the first condensing bend 9 and the second condensing bend 31. The heat on the first condensing bend 9 is promptly conducted away through the first heat-conducting plates 32, thereby improving the condensing effect of the first condensing bend 9.

[0037] Multiple second heat-conducting plates 33 are fixedly connected to the bottom of the second condensing bend 31. The heat on the second condensing bend 31 is promptly conducted away through the second heat-conducting plates 33, thereby improving the condensing effect of the second condensing bend 31.

[0038] Multiple condenser plates 34 are fixedly connected to the inner surfaces of the first condenser bend 9 and the second condenser bend 31. The condenser plates 34 increase the contact area with the wind carrying water vapor, so that the water vapor can be condensed and liquefied more fully, thereby improving the water collection efficiency.

[0039] By inserting the four fixing pipes 3 on the sand-fixing frame 1 into the sand, the installation box 2 and the sand-fixing frame 1 are fixed. Then, water is injected into the installation box 2 through the water inlet pipe 61, and the installation box 2 circulates water into the fixing pipes 3. At the same time, water from one side of the fixing pipe 3 is circulated into the other side of the fixing pipe 3 through the first condensation bend 9 and the second condensation bend 31, thus storing water through the fixing pipes 3. The water-guiding rope 11 on the outlet pipe 10 is buried in the surface of the sand. The water-guiding rope 11 can slowly moisten the sand surface through capillary action. This moistening method not only avoids the water from evaporating too quickly, but also provides a stable water supply for the plants in the sand, which is conducive to the growth and rooting of plants, further enhancing the sand-fixing effect. After the sand surface is slowly moistened by the water-guiding rope 11, the sand-fixing net is fixed on the installation ring 51, which can form an effective protective barrier to prevent the flow and spread of sand. Simultaneously, plants are planted within the sand-fixing frame 1. The plant roots penetrate deep into the sand, forming a three-dimensional sand-fixing system together with the sand-fixing frame 1 and the sand-fixing net. This comprehensively stabilizes the sand enclosed by the sand-fixing frame 1, greatly improving its stability and durability. Furthermore, the planting within the sand-fixing frame 1, along with the sand-fixing frame 1, and the plants, stabilizes the sand within the frame, thus achieving water and soil conservation. Simultaneously, as moisture evaporates from the sand surface, the evaporated water vapor rises. Wind enters through the first air inlet chute 4 in this direction, and is then guided upwards by the first air inlet inclined plate 5. The wind then flows above the sand through the first air inlet chute 4, carrying the evaporated water vapor to the opposite side of the first air inlet chute 4. The first air inlet chute 4 then blocks the wind through the first air inlet inclined plate 5. The air flows into the ventilation duct 6 inside the sand-fixing frame 1, and then is guided through the ventilation duct 6 to the second air inlet duct 7 on the mounting box 2. The air carrying water vapor is then guided into the mounting box 2 through the second air inlet inclined plate 8, and then enters the fixed pipe 3. The fixed pipe 3 passes the air into the first condensation bend 9. When the water level in the fixed pipe 3 drops below the second condensation bend 31, the air also enters the second condensation bend 31. Since the first condensation bend 9 and the second condensation bend 31 are buried underground, their temperatures are low. At this time, the air carrying water vapor is condensed by the condenser plate 34 in the first condensation bend 9 and the second condensation bend 31, causing it to liquefy into water. The accumulated water flows into the fixed pipe 3 for water collection through the first condensation bend 9 and the second condensation bend 31, thereby reducing water consumption and achieving long-term moisture retention and sand fixation in the sand-fixing frame 1.

[0040] Simultaneously, during the wind blowing process, the wind-guiding plate 22 guides the incoming wind upward, reducing the wind's movement and drying effect on the sand, thus further improving the sand-fixing effect. When the wind is strong, the wind-guiding plate 22 rotates under the force of the wind, causing the arc-shaped spring 24 to bend. The arc-shaped spring 24 exerts a downward force on the adjusting plate 23, causing the adjusting plate 23 to move downward. At this time, the spring 25 on the adjusting plate 23 is compressed, and the adjusting plate 23 adjusts the gap between the adjusting plate 23 and the first air inlet inclined plate 5, making the air inlet gap smaller. This achieves automatic adjustment of the wind force in the first air inlet slot 4 according to the wind speed, keeping the wind force above the sand within a certain range, preventing the wind force from being fixed and accelerating the drying and movement of the sand surface, thereby further improving the sand-fixing effect.

[0041] In summary, this device demonstrates excellent water retention and sand fixation effects in practical applications. By combining sand-fixing frames 1, sand-fixing nets, and plants, a tight protective network is formed. Sand-fixing frames 1 provide a stable growing space for the plants, the sand-fixing nets prevent sand movement, and the plant roots penetrate deep into the sand, fixing the sand and absorbing water and nutrients. This three-dimensional sand-fixing system effectively resists wind and sand erosion, reduces sand loss, and creates favorable conditions for ecological restoration.

[0042] In terms of water retention, the device effectively preserves and utilizes water through multiple methods. First, water is injected into the mounting box 2 and the fixed pipe 3 through the water inlet pipe 61 for storage, providing a basic water supply for the sandy area. Second, the water-guiding rope 11 slowly guides the water in the fixed pipe 3 to the surface of the sand, keeping the sand moist and preventing rapid evaporation. More importantly, when the water on the sand surface evaporates, the evaporated water vapor flows upward. At this time, the wind enters through the first air inlet slot 4 in this direction, and after being guided upward by the first air inlet inclined plate 5, the wind flows above the sand. The flowing wind carries the evaporated water vapor to the first air inlet slot 4 on the opposite side, and then the wind is blocked by the first air inlet inclined plate 5, flowing into the ventilation slot 6 in the sand-fixing frame 1. Subsequently, it is guided through the ventilation slot 6 to the second air inlet slot 7 on the mounting box 2, and then the second air inlet inclined plate 8 guides the water vapor-laden wind into the mounting box 2, finally entering the fixed pipe 3. Because the first condensation bend 9 and the second condensation bend 31 are buried underground at low temperatures, the moisture-laden air is condensed into water by the condenser plate 34 within these bends. The accumulated water then flows through the first and second condensation bends 9 and 31 into the fixed pipe 3 for collection. This process forms a water circulation system, significantly reducing water consumption and achieving long-term moisture retention and stabilization of the sand within the sand-fixing frame 1. This provides favorable water conditions for plant growth and promotes the healthy development of the ecosystem.

[0043] Example 2

[0044] Based on Example 1, please refer to Figures 2 to 5 As shown, a water receiving trough 41 is provided on the top of the sand-fixing frame 1, and a water leakage trough 42 is provided inside the water receiving trough 41.

[0045] When it rains, rainwater enters multiple air intake plates 22, which then pour the rainwater into a water collection trough 41 at the top of the sand-fixing frame 1. The water collection trough 41 then guides the rainwater into a drainage trough 42, which in turn leads it into a ventilation duct 6. The ventilation duct 6 then guides the rainwater through a second air inlet duct 7 into the installation box 2. The installation box 2 then guides the rainwater into a fixed pipe 3 for storage, thus collecting rainwater and increasing the water storage capacity of the fixed pipe 3. This design fully utilizes natural rainfall, increases the water storage capacity of the fixed pipe 3, and further enhances the sand-fixing and water-retention effect. In arid regions, rainwater is a precious water resource. The rainwater collection function of this device allows for better utilization of natural rainfall, reduces dependence on external water sources, lowers costs, and improves the practicality and sustainability of the device.

[0046] A method for soil and water conservation to fix sand and retain water includes the following steps:

[0047] Step 1: Insert the fixing pipes 3 on the multiple sand-fixing frames 1 into the required soil and water stabilization positions;

[0048] Step 2: Pour water into the fixed pipe 3 through the water inlet pipe 61, and bury the water-guiding rope 11 in the surface layer of sand.

[0049] Step 3: Plant the plants inside the sand-fixing frame 1, and then fix the sand-prevention net to the installation ring 51 inside the sand-fixing frame.

[0050] Working principle: By inserting the four fixing pipes 3 on the sand-fixing frame 1 into the sand, the mounting box 2 and the sand-fixing frame 1 are fixed. Then, water is injected into the mounting box 2 through the water inlet pipe 61, and the mounting box 2 circulates water into the fixing pipes 3. At the same time, water from one side of the fixing pipe 3 is circulated into the other side of the fixing pipe 3 through the first condensation bend 9 and the second condensation bend 31, thus storing water through the fixing pipes 3. The water-guiding rope 11 on the outlet pipe 10 is buried in the surface of the sand, and then the water-guiding rope 11 slowly dries the sand surface. The sand is moistened with water, and then the sand-fixing net is fixed to the installation ring 51. Simultaneously, plants are planted within the sand-fixing frame 1. The sand-fixing frame 1, the sand-fixing net, and the plants stabilize the sand within the frame, thus achieving water and soil conservation. While conserving water and stabilizing the sand, as moisture evaporates from the sand surface, the evaporated water vapor rises. At this time, wind enters through the first air inlet slot 4 in that direction, and is then guided upwards by the first air inlet inclined plate 5. With the cooperation of the first air inlet slot 4, the wind enters above the sand. The air flows, carrying the evaporated water vapor to the first air inlet slot 4 on the opposite side. The first air inlet slot 4 then blocks the airflow via the first air inlet ramp 5, and the air flows into the ventilation slot 6 inside the sand-fixing frame 1. The ventilation slot 6 then guides the air to the second air inlet slot 7 on the mounting box 2. The second air inlet ramp 8 then guides the water vapor-laden air into the mounting box 2, and finally into the fixed pipe 3. The fixed pipe 3 then directs the air into the first condensation bend 9. When the water level in the fixed pipe 3 drops below the second condensation bend 9... Then, the wind will also enter the second condensation bend 31. Since the first condensation bend 9 and the second condensation bend 31 are buried underground, the temperature of the first condensation bend 9 and the second condensation bend 31 is low. At this time, the wind carrying water vapor is condensed by the condenser plate 34 in the first condensation bend 9 and the second condensation bend 31, so that it is liquefied into water. The accumulated water flows into the fixed pipe 3 through the first condensation bend 9 and the second condensation bend 31 for collection, thereby reducing water consumption and achieving long-term moisture retention and sand fixation in the sand fixation frame 1.

[0051] Simultaneously, during the wind blowing process, the wind-guiding plate 22 guides the incoming wind upward, reducing the wind's movement and drying effect on the sand, thus further improving the sand-fixing effect. When the wind is strong, the wind-guiding plate 22 rotates under the force of the wind, causing the arc-shaped spring 24 to bend. The arc-shaped spring 24 exerts a downward force on the adjusting plate 23, causing the adjusting plate 23 to move downward. At this time, the spring 25 on the adjusting plate 23 is compressed, and the adjusting plate 23 adjusts the gap between the adjusting plate 23 and the first air inlet inclined plate 5, making the air inlet gap smaller. This achieves automatic adjustment of the wind force in the first air inlet slot 4 according to the wind speed, keeping the wind force above the sand within a certain range, preventing the wind force from being fixed and accelerating the drying and movement of the sand surface, thereby further improving the sand-fixing effect.

[0052] When it rains, rainwater enters multiple wind deflectors 22. At this time, the wind deflectors 22 pour the rainwater into the water collection trough 41 at the top of the sand-fixing frame 1. Then, the water collection trough 41 guides the rainwater into the drainage trough 42. The drainage trough 42 guides the rainwater into the ventilation trough 6. Then, the ventilation trough 6 guides the rainwater into the installation box 2 through the second air inlet trough 7. The installation box 2 guides the rainwater into the fixed pipe 3 for storage, thereby realizing the collection of rainwater, increasing the water storage capacity in the fixed pipe 3, and further improving the sand-fixing and water-retention effect of the sand.

[0053] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
