A desert sand-fixing greening device and a desert sand-fixing greening method

Abstract

This application provides a desert sand-fixing and greening device and method, relating to desert sand fixation. It includes a fixing pin and a connecting plate fixed to the surface of the fixing pin. A first sand-fixing plate and a second sand-fixing plate are slidably mounted on the connecting plate. Both the first and second sand-fixing plates have through grooves on their surfaces, into which sand-fixing nylon filaments are inserted. This application, through its binding structure and by replacing conventional straw with sand-fixing nylon filaments, ensures that the nylon filaments are less prone to bending and oxidation after multiple first and second sand-fixing plates enclose a square area. This effectively guarantees the growth of vegetation and effective sand fixation. Furthermore, since the sand-fixing nylon filaments are fixed through the binding structure, they can be released after vegetation growth, allowing for recycling.

Description

Technical Field

[0001] This invention relates to the field of desert sand fixation, and more specifically, to a desert sand fixation and greening device and a desert sand fixation and greening method. Background Technology

[0002] Desertification control refers to curbing the spread of deserts through technologies such as water-based sand control. The main causes of desertification are unreasonable human activities, drought and water scarcity, sparse vegetation, and the amplifying effect of wind. Therefore, if breakthroughs can be found in alleviating water shortages, increasing surface vegetation in desert areas, and reducing the amplifying effect of wind, desertification control can be effectively addressed.

[0003] Currently, the method for stabilizing sand in deserts involves planting straw in designated areas, forming multiple squares with straw stalks, and then planting seeds in the center of these squares to slow down desertification. However, in practical applications, this method has been found to be ineffective in preventing sand and dust accumulation due to the straw's prolonged exposure to air, which easily leads to oxidation and bending. Consequently, it also hinders the growth of vegetation within the enclosed squares, resulting in limited sand control. Therefore, we have proposed an improvement: a desert sand-fixing and greening device and method. Summary of the Invention

[0004] The purpose of this invention is to provide a desert sand-fixing and greening device and method. By setting up a binding structure, the problem of traditional straw being easily oxidized and bent, which is not conducive to sand fixation, is solved.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: A desert sand-fixing and greening device includes a fixing pin and a connecting plate fixed to the surface of the fixing pin, wherein a first sand-fixing plate and a second sand-fixing plate are slidably mounted on the connecting plate. Both the first and second sand-fixing plates have through grooves on their surfaces, and sand-fixing nylon filament bundles are inserted into the through grooves. The first and second sand-fixing plates are provided with binding structures, which can form a tight bond to the sand-fixing nylon filament bundles. The first sand-fixing plate and the second sand-fixing plate are connected by a linkage structure. Rotating the first sand-fixing plate and the second sand-fixing plate can cause the linkage structure to drive the restraint structure to move.

[0006] As a preferred technical solution of this application, the binding structure includes a sliding plate slidably disposed in the corresponding first sand-fixing plate and second sand-fixing plate, a transmission plate connected to one side of the sliding plate, and a drive plate connected to the surface of the transmission plate. One end of the drive plate is fixed with a fastening seat, and the other end of the sliding plate is equipped with a spring. Under the action of the spring, the fastening seat can be moved away from the through groove in a natural state.

[0007] As a preferred technical solution of this application, the linkage structure includes a transmission rope that is connected to the inner sides of the first sand-fixing plate and the second sand-fixing plate, and one end of the transmission rope passes through the first sand-fixing plate and is fixed to the transmission plate inside it. The other end of the transmission rope passes through the second sand-fixing plate and is fixed to the transmission plate inside it. Under natural conditions, the transmission rope is in a taut state due to the action of the spring.

[0008] As a preferred technical solution of this application, one end of the transmission plate further extends into a locking end; The locking end has a sliding locking block inside, and a support spring connected to the inner wall of the locking end is fixed on the surface of the locking block. One end of the locking block is an arc surface and the other end is a plane.

[0009] As a preferred technical solution of this application, a locking groove is provided on the top of the connecting plate, and a first positioning block and a second positioning block are respectively provided in the locking groove. A cover plate for covering the locking groove is also fixed on the surface of the fixing pin.

[0010] As a preferred technical solution of this application, the first sand-fixing plate and the second sand-fixing plate are further fixed with a partition plate, which divides them into an active cavity and a water storage cavity by the action of the partition plate. The partition plate surface is also provided with a strip groove for the movement of the drive plate.

[0011] As a preferred technical solution of this application, a guide cylinder is fixed on the surface of the partition plate at the position corresponding to the through groove, and the two ends of the guide cylinder are respectively in contact with and fixed to the top wall and bottom wall of the corresponding first sand-fixing plate and second sand-fixing plate. A fastening groove is provided on the guide cylinder for fastening the fastening seat.

[0012] As a preferred technical solution of this application, the fastening base is provided with a water storage tank, and the guide cylinder can be connected to the water storage cavity by the action of the water storage tank.

[0013] As a preferred technical solution of this application, a guide bucket is fixed at the top of the first sand-fixing plate and the second sand-fixing plate at the position corresponding to the through groove, and a slow-permeable sponge is embedded at the bottom of the first sand-fixing plate and the second sand-fixing plate. One end of the first sand-fixing plate and the second sand-fixing plate are respectively connected to a first connecting plate and a second connecting plate, and the first connecting plate and the second connecting plate are staggered in the height direction. Furthermore, a connecting fixing pin is inserted into the first connecting plate.

[0014] A desert sand-fixing and greening method using desert sand-fixing and greening devices includes the following steps: Step 1: Insert the sand-fixing nylon filament bundle to be planted into the through groove, and then pull the first sand-fixing plate and the second sand-fixing plate outward to unfold it. During the unfolding process, the transmission plate will drive the fastening seat on the drive plate to slide to form a fastening of the sand-fixing nylon filament bundle. Step 2: Assemble the two sand-fixing devices, place the first connecting plate and the second connecting plate together, and connect them with connecting pins. Finally, insert the fixing pins and connecting pins into the ground to fix them in place. Step 3: Bury the assembled devices in the desert in an orderly manner, and sow vegetation in the center. Step 4: After sowing, water the trench. During the watering process, some water will be injected into the water storage chamber through the water storage tank, and with the help of the slow-seeping sponge, the water will slowly seep into the ground.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the scheme of this application: 1. By setting a binding structure and replacing conventional straw with sand-fixing nylon filaments, the sand-fixing nylon filaments are less prone to bending and oxidation after multiple first and second sand-fixing boards are combined to form a square area. Therefore, the growth of vegetation and effective sand fixation can be effectively guaranteed. At the same time, since the sand-fixing nylon filaments are fixed by the binding structure, they can be unfixed by the binding structure after the vegetation grows, thus achieving recycling. 2. Through the set binding structure and linkage structure, when the first sand-fixing plate and the second sand-fixing plate are close to each other and not unfolded for use, the sand-fixing nylon filament bundle can be directly inserted into the corresponding through groove. When the first sand-fixing plate and the second sand-fixing plate are unfolded and assembled into a square shape, the linkage structure can cause the fastening seat to slide to fix the sand-fixing nylon filament bundle. This allows the first and second sand-fixing plates to be folded and stored, while simultaneously fixing the sand-fixing nylon filament bundles during the unfolding process, facilitating practical applications. 3. Through the design of the locking end and the first and second positioning blocks, when the first and second sand-fixing plates are in the folded state, the locking end is away from the corresponding locking groove, so it can rotate relative to the connecting plate for easy storage. At the same time, when the first and second sand-fixing plates are unfolded, the locking end can slide outward and lock into the locking groove to limit the angle after unfolding, ensuring stability in actual application. 4. Through the design of the partition plate, movable cavity and water storage cavity, water can be poured in the channel to irrigate the edge of the enclosure, which meets the growth of vegetation in the center of the enclosure. At the same time, some water can be input into the water storage cavity through the water storage tank, so as to achieve slow water infiltration with the slow-permeable sponge, which can meet the continuous water needs of vegetation in the center of the enclosure.

[0023] Please see Figures 1 to 10 The present invention provides a technical solution: a desert sand fixation and greening device, including a fixing pin 1 and a connecting plate 11 fixed to the surface of the fixing pin 1, wherein a first sand fixation plate 12 and a second sand fixation plate 13 are slidably assembled on the connecting plate 11 respectively. The first sand-fixing plate 12 and the second sand-fixing plate 13 are both provided with through grooves 14, and sand-fixing nylon filament bundles 15 are inserted into the through grooves 14. The first sand-fixing plate 12 and the second sand-fixing plate 13 are provided with binding structures 2, which can form a tight bond to the sand-fixing nylon filament bundles 15 under the action of the binding structures 2. The first sand-fixing plate 12 and the second sand-fixing plate 13 are connected by a linkage structure 3. Rotating the first sand-fixing plate 12 and the second sand-fixing plate 13 can cause the linkage structure 3 to drive the restraint structure 2 to move. The binding structure 2 includes a sliding plate 21 slidably disposed in the corresponding first sand-fixing plate 12 and second sand-fixing plate 13, a transmission plate 22 connected to one side of the sliding plate 21, and a drive plate 23 connected to the surface of the transmission plate 22. A fastening seat 24 is fixed at one end of the drive plate 23, and a spring 25 is installed at the other end of the sliding plate 21. Under the action of the spring 25, the fastening seat 24 can be moved away from the through groove 14 in a natural state. The linkage structure 3 includes a transmission rope 31 that is connected to the inner sides of the first sand-fixing plate 12 and the second sand-fixing plate 13. One end of the transmission rope 31 passes through the first sand-fixing plate 12 and is fixed to the transmission plate 22 inside it. The other end of the transmission rope 31 passes through the second sand-fixing plate 13 and is fixed to the transmission plate 22 inside it. Under natural conditions, the transmission rope 31 is in a tensioned state due to the action of the spring 25. One end of the transmission plate 22 also extends a locking end 26; A locking block 260 is slidably provided inside the locking end 26, and a support spring 261 connected to the inner wall of the locking end 26 is fixed on the surface of the locking block 260. One end of the locking block 260 is an arc surface and the other end is a plane. The top of the connecting plate 11 is provided with a locking groove 16, and a first positioning block 17 and a second positioning block 18 are respectively provided in the locking groove 16. A cover plate 19 for covering the locking groove 16 is also fixed on the surface of the fixing pin 1. like Figure 1As shown, the first sand-fixing plate 12 and the second sand-fixing plate 13 are at an unexpanded angle. At this time, the locking end 26 is away from the connecting plate 11. When the first sand-fixing plate 12 and the second sand-fixing plate 13 are unfolded, the transmission rope 31 will pull the two transmission plates 22 to slide with the corresponding first sand-fixing plate 12 and the second sand-fixing plate 13. Therefore, the transmission plates 22 will drive the locking end 26 to slide outward during the sliding process. During the sliding process, the locking end 26 will gradually contact the connecting plate 11. When the locking end 26 has slid to one side of the corresponding first positioning block 17 and second positioning block 18, the locking block 260 on the locking end 26 will extend into the locking groove 16. During the extension process, the locking block 260 will first retract into the locking end 26, and then pop out by the action of the support spring 261 to form a complete lock with the locking groove 16. Therefore, the transmission plate 22 will not slide after being locked, thus satisfying the fixation of the sand-fixing nylon filament bundle 15 in the through groove 14. Furthermore, the locking block 260, after being locked with the locking groove 16, will be subjected to the action of the first positioning block 17 and the second positioning block 18 and will not slide in the horizontal direction, thereby ensuring the stability of the device after unfolding. The first sand-fixing plate 12 and the second sand-fixing plate 13 are also fixed with a partition plate 4 inside. The partition plate 4 divides them into an active cavity 41 and a water storage cavity 42. The surface of the partition plate 4 is also provided with a strip groove 43 for the movement of the drive plate 23. A guide cylinder 44 is fixed on the surface of the partition plate 4 at the position corresponding to the through groove 14. The two ends of the guide cylinder 44 are respectively in contact with and fixed to the top and bottom walls of the first sand-fixing plate 12 and the second sand-fixing plate 13. A fastening groove 45 is provided on the guide cylinder 44 for fastening the fastening seat 24; The fastening base 24 is provided with a water storage tank 46, and the guide cylinder 44 can be connected to the water storage cavity 42 by the action of the water storage tank 46. The top of the first sand-fixing plate 12 and the second sand-fixing plate 13 are both fixed with guide buckets 140 at the positions corresponding to the through groove 14, and the bottom of the first sand-fixing plate 12 and the second sand-fixing plate 13 are both embedded with slow-permeable sponges 5. One end of the first sand-fixing plate 12 and the second sand-fixing plate 13 is respectively connected to a first connecting plate 6 and a second connecting plate 7. The first connecting plate 6 and the second connecting plate 7 are staggered in the height direction, and a connecting fixing pin 8 is also inserted on the first connecting plate 6. A desert sand-fixing and greening method using desert sand-fixing and greening devices includes the following steps, such as... Figure 5The device is shown in its unfolded state for use. When in use, the first sand-fixing plate 12 and the second sand-fixing plate 13 need to be pulled outwards. During the pulling process, the transmission rope 31 will pull the transmission plates 22 on both sides to slide. During the sliding process, the transmission plates 22 will overcome the elastic force of the spring 25. At the same time, the transmission plates 22 will drive the fastening seat 24 to slide through the drive plate 23. During the sliding process, the fastening seat 24 will continuously reduce the inner diameter of the through groove 14. Finally, when the first sand-fixing plate 12 and the second sand-fixing plate 13 are fully unfolded (ninety degrees), the fastening seat 24 can be fixed with the sand-fixing nylon filament bundle 15 inserted inside. Then two such Figure 5 The first sand-stabilizing plate 12 and the second sand-stabilizing plate 13, after being unfolded, are assembled to form an enclosure as shown in the figure. Figure 2 As shown, during assembly, the first connecting plate 6 and the second connecting plate 7 can be connected using connecting pins 8, such as... Figure 2 The multiple sand-fixing nylon filament bundles 15 shown can be enclosed to form a square shape, which can be fixed in the desert by fixing pin 1 and connecting fixing pin 8 to achieve overall fixation. After fixation, seeds can be sown inside. In this way, the sand-fixing nylon filament bundles 15 can block sand and dust, prevent desertification, and also promote the growth of sown seeds. In practical applications, multiple assembled cubes can be further combined to form, for example... Figure 4 The state shown allows for large-scale application of sand fixation and greening; During the sand fixation process, the vegetation at the center of the square block needs to be watered regularly. During the watering process, water can be poured into the bottom of the sand-fixing nylon filament bundle 15 through the channel 14, so that the roots of the vegetation can grow outward to absorb water. During the watering process, some water can be input into the water storage chamber 42 through the water storage tank 46 and slowly infiltrated through the slow-permeable sponge 5, thus continuously meeting the water needs of the vegetation after watering.
