Description

Technical Field

[0001] This invention relates to the field of sandy land restoration devices, specifically a sandy land vegetation ecological restoration device for windbreak and sand fixation. Background Technology

[0002] Desertification, a severe global ecological challenge, is particularly prominent in arid and semi-arid regions. These areas suffer from scarce rainfall and sparse vegetation. Under the continuous erosion of strong winds, large amounts of loose surface material are stripped and transported, forming rampant shifting sands that constantly engulf oases and fertile fields. This leads to a sharp decline in land productivity and a severe imbalance in the ecosystem. This process not only erodes precious land resources, exacerbates water shortages, and destroys biodiversity, but also directly threatens regional and even global ecological security barriers. At the same time, frequent sandstorms and soil impoverishment in desertified areas have drastically deteriorated the living and production conditions of local residents, posing a continuous crisis to the human living environment and a profound threat to food security, economic development, and social stability. Global cooperation and scientific governance are urgently needed.

[0003] Patent application CN202121832409.1 discloses a device for ecological restoration of vegetation in sandy areas, including several baffle groups, each baffle group including two baffles connected by a width adjustment device; a support plate with a bottom plate, the support plate being connected to the width connection device via a connecting rod; and support auxiliary devices on both sides of the support plate, the support auxiliary devices including a telescopic rod, an arc plate, and a fixed plate; the telescopic rod passes through the bottom plate and is fixedly connected to one end of the arc plate, the other end of the arc plate is fixedly connected to the fixed plate, and the fixed plate is connected to the support plate via a locking device.

[0004] In summary, due to the insufficient water retention capacity of sandy soil, scarce rainfall, strong evaporation, and severe deep seepage, coupled with the shallow root system of seedlings making it difficult for them to absorb and utilize deep soil moisture, continuous drought under these harsh hydrothermal conditions can easily lead to large-scale seedling mortality, thereby severely restricting the efficiency and effectiveness of ecological restoration of sandy vegetation.

[0005] Therefore, we propose a windbreak and sand-fixing ecological restoration device for desert vegetation. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a windbreak and sand-fixing ecological restoration device for desert vegetation, thereby solving the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a windbreak and sand-fixing ecological restoration device for desert vegetation, comprising a support mechanism, the support mechanism comprising a pre-embedded frame, a connecting rod fixedly connected to the top outer wall of the pre-embedded frame, a connecting plate provided on the top outer side of the connecting rod, bolts movably connected to the inner wall of the connecting plate, the connecting plate being used to fix the pre-embedded frames at different positions by means of bolts, a first through hole being opened on the inner wall of the pre-embedded frame, and a reinforcement mechanism being provided inside the pre-embedded frame;

[0008] The reinforcement mechanism includes:

[0009] The load-bearing plate is slidably connected to the inner wall of the embedded frame. Connecting shafts are fixedly connected to the four right angles at the bottom of the load-bearing plate. The side of the connecting shaft away from the load-bearing plate passes through the embedded frame and is fixedly connected to a limit block.

[0010] The tilting frame has a bend that is rotatably connected to the side bottom wall of the pre-embedded frame. The tilting frame is L-shaped. A fixing plate is fixedly connected to the outer wall of the tilting frame on the side that contacts the soil. A sliding groove is opened through the outer surface of the tilting frame on the side close to the pre-embedded frame. A sliding block is slidably connected to the inner wall of the sliding groove.

[0011] According to the above technical solution, the outer surface of the stress plate is provided with vent holes, and a concave block is fixedly connected to the inner wall of the side of the stress plate near the vent holes. The concave block is used to store liquid water to prevent the soil and water from being lost too quickly.

[0012] According to the above technical solution, a spring is fixedly connected to the bottom outer wall of the force-bearing plate. The end of the spring away from the force-bearing plate is fixedly connected to the inner wall of the pre-embedded frame. The spring is movably sleeved on the outer surface of the connecting shaft and is used to assist the force-bearing plate to slide upward.

[0013] According to the above technical solution, the outer periphery of the limiting block is rotatably connected to a rotating rod via a rotating shaft. The end of the rotating rod away from the limiting block is rotatably connected to the inner wall of the sliding block. The limiting block is used to push the sliding block to slide along the inner wall of the sliding groove via the rotating rod.

[0014] According to the above technical solution, connecting blocks are fixedly connected to the inner walls of the four sides of the pre-embedded frame, and an auxiliary component is provided on the outside of the pre-embedded frame. The auxiliary component includes a first connecting pipe fixedly connected to the inner wall of the connecting block. A movable block is movably sleeved on the outer wall of the first connecting pipe away from the connecting block. The movable block is movably sleeved on the outer surface of the first connecting pipe and can rotate or slide left and right along the outer surface of the first connecting pipe.

[0015] According to the above technical solution, a second connecting pipe is fixedly connected to the outer wall of the first connecting pipe on the side away from the movable block, and a connector is fixedly connected to the outer wall of the second connecting pipe on the end away from the first connecting pipe. The inner wall of the connector is provided with an internal thread for threaded connection with a movable block set outside another pre-embedded frame.

[0016] According to the above technical solution, a first fixing pipe is fixedly connected to the outer wall of the first connecting pipe near the pre-embedded frame, and a first nozzle is fixedly connected to the outer wall of the first fixing pipe away from the first connecting pipe. The first fixing pipe is used to transport the water inside the first connecting pipe toward the first nozzle, and the first nozzle can adjust the water flow rate.

[0017] According to the above technical solution, a third connecting pipe is fixedly connected to the outer wall of the first connecting pipe near the second connecting pipe. The outer surface of the third connecting pipe is fixedly connected to the inner wall of the connecting block. A second fixing pipe is fixedly connected to the outer wall of the third connecting pipe near the pre-embedded frame. A second nozzle is fixedly connected to the outer wall of the second fixing pipe away from the third connecting pipe. The third connecting pipe is used to transport water inside the first connecting pipe to the second fixing pipe.

[0018] Compared with existing technologies, the present invention provides a windbreak and sand-fixing ecological restoration device for desert vegetation, which has the following beneficial effects:

[0019] 1. This invention utilizes a windbreak and sand-fixing ecological restoration device for desert vegetation. When plants are placed on a support plate, the plate slides downwards along the inner wall of a pre-embedded frame under the weight of the plants, burying the plant roots deeper into the soil. This creates a relatively stable moisture environment, effectively mitigating the impact of surface soil drought stress on seedlings. Simultaneously, the support plate temporarily retains water through the water-retaining spaces formed by the concave blocks, providing sufficient time for root absorption and improving water use efficiency. Its ability to delay water loss significantly reduces the ineffective consumption of precious water resources in arid regions, thereby increasing seedling survival rates.

[0020] 2. This invention sets up a support mechanism and fixes the connecting rods at the top of each pre-embedded frame to the connecting plate and bolts to form an integrated array structure. On this basis, the movable block near the connecting head is connected to the connecting head, so that the water channels of the first connecting pipe and the third connecting pipe outside the multiple pre-embedded frames are connected. The water supply pipe is connected through the outermost movable block to build a unified water supply network, thereby realizing centralized water supply to the first connecting pipe and the third connecting pipe, thereby improving the water supply efficiency of vegetation planting areas in arid sandy environments.

[0021] 3. This invention, through the setting of auxiliary components and the diversion design, delivers water to the first fixed pipe, the second connecting pipe, and the third connecting pipe. The second connecting pipe, as a horizontal water supply hub, continuously replenishes the water source for each of the parallel-arranged first connecting pipes, ensuring the water balance of the entire irrigation network. The first fixed pipe, through the first sprinkler, uses drip irrigation technology to directly deliver water to the soil at the roots of the vegetation, minimizing water evaporation and loss. The third connecting pipe, as a vertical water conveyance link, directs the water source to the second fixed pipe, which then performs drip irrigation on the vegetation through the second sprinkler. This effectively avoids the problems of excessive flooding and evaporation loss in traditional irrigation methods, and improves the efficiency of water resource utilization.

[0022] 4. This invention, by setting up a reinforcement mechanism, places the plants to be planted on the force plate. Under the action of the plant's gravity, the force plate slides to the bottom along the guide structure inside the pre-embedded frame. During this process, the force plate drives the bottom fixed limit block to move down synchronously through the connecting shaft. The rotating rod connected to the inner wall of the limit block plays a transmission function, pushing the sliding block to slide along the inner wall of the pre-set sliding groove on the outer surface of the flipping frame. This causes the flipping frame to flip around the connection point of the bottom inner wall of the pre-embedded frame. After the flipping frame completes the angle flipping, its contact area with the sand increases, effectively improving the friction coefficient between the flipping frame and the sand, and greatly enhancing the pull-out resistance.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0034] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] Example 1: See Figures 1-3 , Figure 6 , Figure 7 , Figure 8 The present invention provides a technical solution: a windbreak and sand fixation ecological restoration device for desert vegetation, including a support mechanism 1, the support mechanism 1 including a pre-embedded frame 101, a connecting rod 104 fixedly connected to the top outer wall of the pre-embedded frame 101, a connecting plate 106 provided on the top outer side of the connecting rod 104, a bolt 107 movably connected to the inner wall of the connecting plate 106, the connecting plate 106 is used to fix the pre-embedded frame 101 at different positions through the bolt 107, a first through hole 105 is opened on the inner wall of the pre-embedded frame 101, and a reinforcement mechanism 2 is provided inside the pre-embedded frame 101;

[0036] Reinforcement mechanism 2 includes:

[0037] The load-bearing plate 201 is slidably connected to the inner wall of the embedded frame 101. Connecting shafts 204 are fixedly connected to the four right angles at the bottom of the load-bearing plate 201. The side of the connecting shaft 204 away from the load-bearing plate 201 passes through the embedded frame 101 and is fixedly connected to the limiting block 206.

[0038] The tilting frame 209 is rotatably connected to the side bottom wall of the pre-embedded frame 101 at its bend. The tilting frame 209 is L-shaped. A fixing plate 211 is fixedly connected to the outer wall of the side of the tilting frame 209 that is in contact with the soil. A sliding groove 210 is opened through the outer surface of the tilting frame 209 near the pre-embedded frame 101. A sliding block 208 is slidably connected to the inner wall of the sliding groove 210. A rotating rod 207 is rotatably connected to the outer periphery of the limiting block 206 via a rotating shaft. The rotating rod 207 is away from the limiting block 206. One end of the sliding block 208 is rotatably connected to the inner wall of the sliding block 208. The limiting block 206 is used to push the sliding block 208 to slide along the inner wall of the sliding groove 210 via the rotating rod 207. In the planting operation of vegetation in sandy land, the first step is to accurately excavate a suitable foundation pit in the sandy land according to the specifications and dimensions of the pre-embedded frame 101. After the pre-embedded frame 101 is firmly placed in the foundation pit, the plants to be planted are placed on the load-bearing plate 201. As the weight of the plants is applied, the load-bearing plate 201 slides to the bottom along the internal guide structure of the pre-embedded frame 101. During this process, the force plate 201 drives the bottom fixed limit block 206 to move down synchronously through the connecting shaft 204. The rotating rod 207 connected to the inner wall of the limit block 206 plays a transmission role, pushing the sliding block 208 to slide along the inner wall of the sliding groove 210 preset on the outer surface of the flipping frame 209. This causes the flipping frame 209 to flip around the connection point of the bottom inner wall of the pre-embedded frame 101 as the axis. After the flipping frame 209 completes the angle flipping, its contact area with the sand increases, thereby effectively improving the friction coefficient between the flipping frame 209 and the sand, greatly enhancing its pull-out resistance, and thus ensuring the stability of the vegetation planting system in the wind and sand environment. In addition, the fixed plate 211 fixedly connected to the outer surface of the flipping frame 209 increases the roughness of the sand surface, effectively hindering the flow of sand particles, forming a physical barrier against sand slippage, further strengthening the stability of the soil around the vegetation roots, and providing favorable site conditions for the growth and development of seedlings. The seedlings are shallow-rooted sandy fruit trees with shallow root system characteristics.

[0039] Ventilation holes 202 are provided on the outer surface of the load-bearing plate 201. A recess 203 is fixedly connected to the inner wall of the load-bearing plate 201 near the ventilation holes 202. The recess 203 is used to store liquid water to prevent excessive soil erosion. A spring 205 is fixedly connected to the bottom outer wall of the load-bearing plate 201. The end of the spring 205 away from the load-bearing plate 201 is fixedly connected to the inner wall of the pre-embedded frame 101. The spring 205 is movably sleeved on the outer surface of the connecting shaft 204. The spring 205 is used to assist the load-bearing plate 201 in sliding upward. When a plant is placed on top of the load-bearing plate 201, its own weight causes the load-bearing plate 201 to slide along the inner wall of the pre-embedded frame 101 toward the flipping frame 209. During this process, the spring 205 is compressed to form an elastic buffer. The ventilation holes 202 on the outer surface of the load-bearing plate 201... 2 is used for drainage, which can promptly remove excess water from the bottom and prevent water accumulation in the pre-buried frame 101. If water accumulates, it will lead to severe soil hypoxia, forcing plant roots to undergo anaerobic respiration and produce toxic substances such as alcohol, which may eventually cause root rot and plant death. The concave block 203 fixedly connected to the inner wall of the load-bearing plate 201 can regulate water. The concave block 203 provides temporary water retention space, prolongs the root absorption time, improves water resource utilization efficiency, and effectively slows down the infiltration rate of water, avoiding excessive loss of precious water resources in arid areas. Thus, it not only eliminates the risk of water accumulation and root rot, but also meets the water needs of plant growth by controlling water, enhancing the survival ability of sandy vegetation in arid environments.

[0040] Sandy land ecosystems face multiple adverse challenges. Their extremely low soil water-holding capacity, coupled with scarce rainfall, intense evaporation, and deep infiltration, makes it difficult to retain soil moisture. Furthermore, the shallow root systems of newly formed seedlings cannot reach the limited water storage layer in the deeper soil layers. Under prolonged drought stress, they are highly susceptible to large-scale mortality due to water deficiency, severely hindering the progress and effectiveness of sandy land vegetation ecological restoration projects. Therefore, a reinforcement mechanism 2 is installed to improve the survival and adaptability of seedlings. After the plants are placed on the load-bearing plate 201, the load-bearing plate 201... Under the influence of gravity, the plant roots slide downwards along the inner wall of the pre-embedded frame 101, allowing them to be buried deeper into the soil. This provides a relatively stable moisture environment and effectively alleviates the impact of surface soil drought stress on seedlings. At the same time, the water-retaining space formed by the concave block 203 in the load-bearing plate 201 can temporarily retain water, providing sufficient time for the roots to absorb water. This improves water use efficiency and slows down water loss, greatly reducing the ineffective consumption of precious water resources in arid areas and thus increasing the survival rate of seedlings.

[0041] Example 2: Please refer to Figures 4-5Based on Embodiment 1, the present invention provides the following technical solution: Connecting blocks 102 are fixedly connected to the inner walls of all four sides of the pre-embedded frame. An auxiliary component 108 is provided on the outside of the pre-embedded frame 101. The auxiliary component 108 includes a first connecting pipe 1081 fixedly connected to the inner wall of the connecting blocks 102. A movable block 1082 is movably sleeved on the outer wall of the first connecting pipe 1081 away from the connecting blocks 102. The movable block 1082 is movably sleeved on the outer surface of the first connecting pipe 1081 and can rotate or slide left and right along the outer surface of the first connecting pipe 1081. A second connecting pipe 1085 is fixedly connected to the outer wall of the first connecting pipe 1081 away from the movable block 1082. A connector 1086 is fixedly connected to the outer wall of the second connecting pipe 1085 away from the first connecting pipe 1081. The inner wall of the connector 1086 is provided with an internal thread for connecting to another movable block 108. Threaded connections are made between the 2 pre-embedded frames 101. When multiple pre-embedded frames 101 are arranged side by side, the connecting rods 104 at the top of each pre-embedded frame 101 are fixedly connected by the connecting plate 106 and the bolts 107 to form an integrated array structure. On this basis, the movable block 1082 on the side near the connector 1086 is connected to the connector 1086, thereby connecting the water channels of the first connecting pipe 1081 and the third connecting pipe 1087 set on the outside of the multiple pre-embedded frames 101. The water supply pipe is connected through the outermost movable block 1082, thereby constructing a unified water supply network and realizing centralized water supply to the first connecting pipe 1081 and the third connecting pipe 1087. This not only enhances the structural stability of the pre-embedded frame array, but also improves the water supply efficiency of the vegetation planting area in the arid sandy environment through the connection of the water channels, providing a reliable infrastructure guarantee for large-scale vegetation restoration projects.

[0042] A first fixed pipe 1083 is fixedly connected to the outer wall of the first connecting pipe 1081 near the pre-embedded frame 101. A first nozzle 1084 is fixedly connected to the outer wall of the first fixed pipe 1083 away from the first connecting pipe 1081. The first fixed pipe 1083 is used to transport water from inside the first connecting pipe 1081 to the first nozzle 1084. The first nozzle 1084 can adjust the water flow rate. A third connecting pipe 1087 is fixedly connected to the outer wall of the first connecting pipe 1081 near the second connecting pipe 1085. The outer surface of the third connecting pipe 1087 is fixedly connected to the inner wall of the connecting block 102. A second fixed pipe 1088 is fixedly connected to the outer wall of the pipe 1087 near the pre-embedded frame 101. A second nozzle 1089 is fixedly connected to the outer wall of the second fixed pipe 1088 away from the third connecting pipe 1087. The first nozzle 1084 and the second nozzle 1089 are located inside the pre-embedded frame 101 and are blocked by the pre-embedded frame 101 and the connecting block 102. The first nozzle 1084 and the second nozzle 1089 are set at a slightly downward angle to avoid clogging of the first nozzle 1084 and the second nozzle 1089 by mud and sand. The third connecting pipe 1087 is used to direct the water inside the first connecting pipe 1081 towards the... The second fixed pipe 1088 delivers water from one side. After water is injected into the first connecting pipe 1081, this pipeline, through a diversion design, delivers water to the first fixed pipe 1083, the second connecting pipe 1085, and the third connecting pipe 1087. The diameter of the first connecting pipe 1081 is larger than that of the third connecting pipe 1087. The first connecting pipe 1081 is the main pipeline, and the third connecting pipe 1087 is a branch pipe. The second connecting pipe 1085 functions as a horizontal water supply hub, continuously replenishing water to the parallel-arranged first connecting pipes 1081 to ensure a balanced water supply throughout the irrigation network. The first fixed pipe 1083, through a distribution... The first sprinkler 1084 of the system uses drip irrigation technology to deliver water directly to the soil around the roots of the vegetation, minimizing water evaporation and loss. The third connecting pipe 1087 serves as a longitudinal water transport link, directing water to the second fixed pipe 1088, which then drip-irrigates the vegetation through the second sprinkler 1089. This irrigation system combines tiered water supply with drip irrigation to create a multi-level water-saving irrigation system, effectively avoiding problems such as excessive flooding and evaporation loss in traditional irrigation methods. This improves the efficiency of water resource utilization and achieves efficient conservation and rational allocation of water resources during vegetation irrigation in arid regions.

[0043] The high porosity of sandy soils causes water to rapidly infiltrate into deep soil layers that are difficult for plant roots to reach. Combined with strong surface evaporation, a large amount of water is lost before being absorbed and utilized by plants, thus exacerbating water resource depletion. To address this, an auxiliary component 108 is installed to optimize irrigation layout and improve water utilization efficiency. The recessed installation design of the first sprinkler 1084 and the second sprinkler 1089 allows the sprinklers to still be positioned in the plant root zone even when the top of the pre-embedded frame 101 is covered by sand. This design effectively avoids the dual losses of water evaporation and deep infiltration in traditional surface irrigation, enabling irrigation water to directly reach plant roots for accurate water supply. By reducing ineffective water loss, the efficiency of water resource utilization in arid regions is improved, providing a reliable water guarantee for the ecological restoration of sandy vegetation.
