Abstract
Description
Technical Field
[0001] This utility model relates to the field of ecological governance technology, specifically a wind-erosion resistant plant sand-fixing module for the Yellow River sand-covered area. Background Technology
[0002] The Yellow River sand-covered area refers to the region along and around the Yellow River that is significantly affected by wind and sand activity, with the surface covered by mobile or semi-mobile sand dunes. It is mainly distributed on the desert edges, riverbank beaches, and some tributary basins in the middle and upper reaches of the Yellow River. These areas are rich in sand sources, suffer from severe wind erosion, and are ecologically fragile due to natural and human factors, making them a key focus of ecological governance in the Yellow River Basin. In the Yellow River sand-covered area, wind erosion is one of the key factors affecting the survival rate of seeds in plant-based sand-fixing modules. Wind erosion not only directly blows away seeds but also alters the surface microenvironment, affecting seed germination and seedling growth. Common plant-based sand-fixing modules include traditional sand barriers, chemical sand-fixing agents, and seed coating technology.
[0003] However, common traditional sand barriers only reduce wind speed and have limited effect on fixing and protecting seeds. Tiny seeds may still slip through the grid, resulting in uneven sowing or even a complete lack of seeds in some areas. Moreover, during wind erosion, the accumulation of sand may bury seeds too deeply, preventing them from germinating, or wind erosion may strip away the topsoil, exposing seeds to drought or strong ultraviolet radiation. This makes the soil conditions around the seeds more susceptible to the effects of wind erosion, thus reducing the germination rate. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a wind-erosion resistant plant sand-fixing module for the Yellow River sand-covered area.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A wind-erosion resistant plant-based sand-fixing module for the Yellow River sand-covered area includes:
[0007] A sand-stabilizing frame, wherein the sand-stabilizing frame is filled with a planting layer;
[0008] A fixing plate is fixed inside the sand-fixing frame and is located above the planting layer, with a gap between the fixing plate and the planting layer. At the same time, multiple sets of through grooves are symmetrically opened on the surface of the fixing plate.
[0009] The protective plates are symmetrically rotated and arranged in the same through groove. Multiple sets of light-transmitting holes are opened at equal intervals along the length direction at the contact surfaces of the two sets of protective plates. At the same time, multiple sets of limiting plates are fixed at equal intervals at the top of the two sets of protective plates near the contact surfaces. All sets of limiting plates span the contact surfaces of the two sets of protective plates.
[0010] Preferably, the protective plate has a rectangular structure, and the two sets of mutually abutting protective plates can completely cover the opening of the through groove.
[0011] Preferably, a buffer groove is provided at the bottom end of the protective plate near the contact surface, and the light-transmitting hole is connected to the buffer groove. At the same time, both the light-transmitting hole and the buffer groove are located above the seeds in the planting layer.
[0012] Preferably, a fixing groove is formed on the top of the protective plate along the length of the contact surface. The fixing groove and the light-transmitting hole are staggered, and the depth of the fixing groove is equal to the thickness of the limiting plate. At the same time, the number and position of the fixing grooves formed on the contact surfaces of the two sets of protective plates correspond one-to-one.
[0013] Preferably, the limiting plate has a cuboid structure, the length of the limiting plate is equal to twice the length of the fixing groove, and the multiple sets of limiting plates fixed by the two sets of protective plates are staggered.
[0014] Preferably, multiple sets of flow-blocking blocks are fixed to the top of the protective plate on the windward side of the fixed plate, and the number and position of the flow-blocking blocks and the light-transmitting holes correspond one-to-one. At the same time, the flow-blocking blocks are right-angled triangular prism shells, and the inclined surface of the flow-blocking blocks faces away from the light-transmitting holes.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] By combining sand-fixing frames, planting layers, fixing plates, protective plates, and limiting plates, this sand-fixing module can provide a relatively stable growth environment for the seeds of wind-erosion resistant plants. This reduces the chance of seeds being dislodged from their original position due to wind erosion, ensuring that seeds are sown evenly. At the same time, it can also prevent seeds from being buried too deep or directly exposed to the outside world due to wind erosion, thereby improving the germination rate of seeds and the survival rate of seedlings.

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0024] Example
[0025] like Figures 1 to 4 As shown, a wind-erosion resistant vegetation sand-fixing module for the Yellow River sand-covered area includes:
[0026] Sand-fixing frame 1, wherein the sand-fixing frame 1 is filled with a planting layer 12;
[0027] The fixing plate 3 is fixed inside the sand-fixing frame 1 and is located above the planting layer 12. A gap is left between the fixing plate 3 and the planting layer 12. At the same time, multiple sets of through grooves 31 are symmetrically opened on the surface of the fixing plate 3.
[0028] The protective plates 4 are symmetrically rotated and arranged in the same through groove 31. Multiple sets of light-transmitting holes 42 are opened at equal intervals along the length direction at the abutting surfaces of the two sets of protective plates 4. At the same time, multiple sets of limiting plates 41 are fixed at equal intervals at the top of the two sets of protective plates 4 near the abutting surfaces. The multiple sets of limiting plates 41 span the abutting surfaces of the two sets of protective plates 4.
[0029] Specifically, the sand-fixing module is first placed in a suitable location in the Yellow River sand-covered area. The planting layer 12 at the bottom of the inner cavity of the sand-fixing frame 1 is mixed with soil water-retaining agent. Planting pits are opened at the positions of the planting layer 12 relative to the through groove 31 and the light-transmitting hole 42. Wind-erosion resistant plant seeds are planted in the pits. The two sets of protective plates 4 installed by the through groove 31 are pushed to rotate, so that the two sets of protective plates 4 can abut against each other and block the through groove 31, providing a relatively closed and stable space for the seeds and reducing the impact of external wind and sand on the soil around the seeds.
[0030] Among them, the lower surface of the sand-fixing frame 1 is fixed with an interception net, which can not only help support the planting layer 12 and prevent the planting layer 12 from accidentally falling off the sand-fixing frame 1, but also ensure the root extension of the wind-erosion resistant plants in the subsequent growth process. Furthermore, four sets of support pillars can be symmetrically fixed at the four corners of the upper surface of the sand-fixing frame 1, and sand-shielding nets can be fixed at the top of the four sets of support pillars to help reduce wind speed and intercept sand and dust.
[0031] Meanwhile, when wind and sand blow across the upper surfaces of the fixed plate 3 and the protective plate 4, the two sets of protective plates 4, which are movably installed within the same through groove 31, are locked together by staggered limiting plates 41. This allows the airflow to quickly pass from one set of protective plates 4 to the other. Because the airflow direction and the rotation plane of the two sets of protective plates 4 are coplanar, the protective plate 4 at the windward end will not be lifted by the airflow; instead, its rotation will be restricted. The protective plate 4 at the leeward end, with the assistance of the limiting plates 41, cannot rotate independently without the windward protective plate 4 rotating. Consequently, the leeward protective plate 4 will not be lifted from the outside due to air pressure changes, ensuring the shielding effect of the through groove 31 opening in the fixed plate 3 and reducing the risk of wind damage around the seeds. The soil environment is affected by excessive sand accumulation due to wind erosion, which can cause seeds to be buried too deep or the surface soil of the planting layer 12 to be blown away, increasing the chances of seeds being directly exposed to the external environment. After the seeds germinate, the gap between the protective plate 4 and the planting layer 12 allows the seedlings to develop for a period of time, improving their robustness. The light-transmitting holes 42 set at the contact surface of the protective plate 4 can provide appropriate light for the seedlings and guide their growth direction. The protective plate 4 is made of biodegradable lightweight plastic, ensuring that the wind-erosion resistant plant seedlings can push open the corresponding two sets of protective plates 4 from bottom to top during the growth process, thereby improving the germination rate of wind-erosion resistant plant seeds and not interfering with the subsequent growth of wind-erosion resistant plants.
[0032] The protective plate 4 has a rectangular structure, and the two sets of mutually abutting protective plates 4 can completely cover the opening of the through groove 31.
[0033] Specifically, the installation of two sets of protective plates 4 can effectively reduce the connection area between the through groove 31 and the soil of the planting layer 12 below it and the external environment, thereby effectively reducing the impact of external wind and sand on the soil of the planting layer 12 and ensuring that wind-erosion resistant plant seeds can germinate in a suitable soil environment.
[0034] A buffer groove is provided at the bottom end of the protective plate 4 near the contact surface, and the light-transmitting hole 42 is connected to the buffer groove. At the same time, both the light-transmitting hole 42 and the buffer groove are located above the seeds in the planting layer 12.
[0035] Specifically, the buffer trough facilitates seed sowing and subsequent seed germination and growth. At the same time, the light-transmitting hole 42 provides appropriate light for the seedlings and helps balance the composition of the gas above the planting layer 12.
[0036] The top of the protective plate 4 has a fixing groove along the length of the contact surface. The fixing groove and the light-transmitting hole 42 are staggered. The depth of the fixing groove is equal to the thickness of the limiting plate 41. At the same time, the number and position of the fixing grooves at the contact surfaces of the two sets of protective plates 4 correspond one-to-one.
[0037] Specifically, the staggered distribution of the fixing groove and the light-transmitting hole 42 can avoid mutual interference between the light-transmitting hole 42 and the protective plate 4. Moreover, the symmetrical fixing grooves of the two sets of protective plates 4 facilitate the corresponding insertion of the fixing limit plate 41, improve the locking effect between the protective plates 4, and prevent the protective plates 4 from being blown away by wind and sand. At the same time, the upper surfaces of the limiting plate 41 and the protective plate 4 are in the same plane, which can reduce the interference effect of airflow on the limiting plate 41.
[0038] The limiting plate 41 has a cuboid structure, and the length of the limiting plate 41 is equal to twice the length of the fixing groove. The multiple sets of limiting plates 41 fixed by the two sets of protective plates 4 are staggered.
[0039] Specifically, the staggered limiting plates 41 between the two sets of protective plates 4 can balance the weight distribution of the protective plates 4 and help reduce the difficulty of the seedlings being pushed open.
[0040] Multiple sets of flow-blocking blocks 43 are fixed on the top of the protective plate 4 on the windward side of the fixed plate 3. The number and position of the flow-blocking blocks 43 and the light-transmitting holes 42 correspond one-to-one. At the same time, the flow-blocking blocks 43 are right-angled triangular prism shells, and the inclined surface of the flow-blocking blocks 43 is away from the light-transmitting holes 42.
[0041] Specifically, the shell structure of the flow-blocking block 43 can effectively reduce the weight of the flow-blocking block 43, thereby reducing the interference effect of the flow-blocking block 43 on the seedlings pushing open the protective plate 4. Moreover, the inclined surface of the flow-blocking block 43 is away from the light-transmitting hole 42, so it can effectively change the flow path of wind and sand, thereby reducing the probability of sand falling from the light-transmitting hole 42 onto the surface of the planting layer 12.
[0042] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
