Description

Technical Field

[0001] This application relates to the field of desertification control and ecological restoration technology, and in particular to a half-width directional brush-like rope sand barrier structure, its manufacturing method and application. Background Technology

[0002] In global ecological and environmental governance, wind erosion severely impacts land resources, ecological balance, and human production and lives, making windbreak and sand fixation, along with ecological restoration, critical issues that urgently need to be addressed. Traditional brush-like netting is a commonly used tool in windbreak and sand fixation. While it can reduce wind and sand velocity and decrease dust migration through physical obstruction, it has significant limitations, such as:

[0003] Firstly, its function is limited: relying solely on physical barriers to combat wind and sand cannot fundamentally improve the ecological environment. Over time, the blocked sand and dust will accumulate around the net ropes, making it easy for the accumulated sand and dust to flow again after the net ropes are damaged, and the wind and sand hazards can easily rebound.

[0004] Secondly, it lacks ecological restoration capabilities: it cannot actively promote vegetation growth, cannot achieve self-recovery of the ecosystem, and is unable to meet the current needs of ecological environment governance;

[0005] Third, the governance efficiency is low: existing ecological restoration technologies and windbreak and sand fixation measures are independent of each other, resulting in high governance costs, low efficiency, and unsustainable effects. Summary of the Invention

[0006] The main purpose of this application is to provide a half-width directional brush-shaped net rope sand barrier structure, its manufacturing method and application, which is suitable for windbreak and sand control, windbreak and sand fixation and ecological restoration in large photovoltaic bases, and can effectively solve the problem of the single function of sand barriers in the existing technology.

[0007] To achieve the above-mentioned objectives, this application provides the following technical solution.

[0008] The first aspect of this application provides a half-width directional brushed rope sand barrier structure, comprising:

[0009] The net rope skeleton includes at least one seed rope and multiple fixing ropes. The multiple fixing ropes are intertwined around the axis of the net rope skeleton to form a spiral structure. The seed rope is arranged between the multiple fixing ropes and is parallel to the axis of the net rope skeleton.

[0010] Multiple brush-shaped units are arranged sequentially along the net rope skeleton, with adjacent brush-shaped units closely attached to each other. Each brush-shaped unit includes multiple bristle ribs fixedly connected to the net rope skeleton. The multiple bristle ribs are distributed in a comb-like pattern, so that the cross-section of the brush-shaped unit in the direction perpendicular to the axis of the net rope skeleton is semi-circular.

[0011] In one embodiment, the brush-like unit includes a bundle of grass, which is formed by the aggregation of multiple plant stems. The bundle is composed of a first structural segment, a second structural segment, and a third structural segment connected sequentially along its length. The second structural segment is located in the middle of the bundle and is fixedly connected to the net rope skeleton. The first and third structural segments are symmetrically arranged, and the plant stems therein are scattered to form the brush bristles.

[0012] In one embodiment, the second structural segment is bent into a ring and wraps around the net rope skeleton; the tail end of the first structural segment contacts the left side of the net rope skeleton, and the head end extends to the upper right of the net rope skeleton; the head end of the third structural segment contacts the right side of the net rope skeleton, and the tail end extends to the upper left of the net rope skeleton.

[0013] In one embodiment, the half-width directional brush-like rope sand barrier structure includes a straw curtain woven from warp threads and a plurality of straw bundles as weft threads, the warp threads intersecting and joining with the second structural segment.

[0014] In one embodiment, the warp is two or more warps spaced apart from each other.

[0015] In one embodiment, the grass bundle is further secured to the rope skeleton by biodegradable braided thread that passes between plant stems, so that the multiple bristle ribs maintain the comb-like distribution.

[0016] In one embodiment, the porosity of the rope skeleton is 30%-60%.

[0017] In one embodiment, the spacing between adjacent brush ribs is 5-15cm.

[0018] In one embodiment, the winding spacing of the multiple knotted ropes spirally wound around the seed rope is 8-20 cm.

[0019] In one embodiment, the diameter of the seed rope and the fixing rope is 2.5-3.5cm.

[0020] In one embodiment, the length of the brush bristles is 20-50cm.

[0021] In one embodiment, the securing rope comprises a straw rope.

[0022] In one embodiment, the plant stems include, but are not limited to, rice straw or wheat straw.

[0023] In one embodiment, the seed rope is further bonded to the fixing rope with a biodegradable adhesive.

[0024] In one embodiment, the seed rope comprises multiple desert plant seeds, a core rope, and a shell layer. The core rope is formed by winding and twisting hemp fabric, and the multiple desert plant seeds are wrapped inside the core rope. The core rope is impregnated with an insect repellent. The shell layer is wrapped around the core rope, and a starch-grafted acrylic copolymer absorbent material is filled between the shell layer and the core rope. The shell layer is formed by winding hemp fabric.

[0025] A second aspect of this application also provides a method for manufacturing a half-width directional brush-like net rope sand barrier structure, the method comprising the following steps:

[0026] Multiple seeds of desert plants are placed sequentially on the hemp fabric along its length. The hemp fabric is then rolled and twisted, soaked in an insect repellent, and then dried to obtain the core rope.

[0027] Place the core rope on the hemp fabric, and evenly spread starch-grafted acrylic copolymer absorbent material on the hemp fabric. Then, wrap the hemp fabric around the core rope to form a seed rope.

[0028] Using the seed rope as the axis, multiple knotted ropes are spirally wound around the seed rope to form a net rope skeleton;

[0029] A straw mat is provided, the straw mat being woven from warp threads and a plurality of bundles of straw as weft threads;

[0030] The net rope frame is placed in the center of the straw mat, and the axis of the net rope frame is perpendicular to each straw bundle. The straw bundle is composed of a first structural segment, a second structural segment, and a third structural segment connected in sequence along the length direction. The second structural segment is located in the middle of the straw bundle, and the first and third structural segments are symmetrically arranged.

[0031] The second structural segment of each grass bundle is bent into a loop and wrapped around the netting frame. The first structural segment extends to the upper right side of the netting frame, and the third structural segment extends to the upper left side of the netting frame. Then, the plant stems in the first and third structural segments are broken apart to form multiple brush ribs. Biodegradable braided thread is then inserted between the broken plant stems to sew and fix the grass bundle to the netting frame, so that the multiple brush ribs are stably maintained in a comb-like distribution, thereby obtaining a brush-shaped unit.

[0032] The third aspect of this application also provides the use of a half-width directional brushed rope sand barrier structure in the construction of facilities for sand control and ecological restoration in photovoltaic power plants.

[0045] Figure 9This is a flowchart illustrating the manufacturing method of the half-width directional brush-shaped net rope sand barrier structure in this application embodiment. Detailed Implementation

[0046] This application provides a half-width directional brush-shaped net rope sand barrier structure suitable for windbreak and sand fixation, as well as ecological restoration in large photovoltaic bases, along with its manufacturing method and application. This addresses the problems of existing brush-shaped net ropes having limited functionality, inability to achieve ecological restoration, and low governance efficiency.

[0047] Specifically, such as Figure 1 As shown, this application embodiment provides a half-width directional brush-shaped net rope sand barrier structure, including a net rope skeleton 1 and multiple brush-shaped units fixed on the net rope skeleton 1. The net rope skeleton 1 includes at least one seed rope 2 and multiple fixing ropes 4. The multiple fixing ropes 4 are intertwined around the axis of the net rope skeleton to form a spiral structure. The seed rope 2 is disposed between the multiple fixing ropes 4 and is arranged parallel to the axis of the net rope skeleton 1.

[0048] Multiple brush-like units are arranged sequentially along the net rope skeleton 1, with adjacent brush-like units closely attached to each other. Each brush-like unit includes multiple bristles 3 fixedly connected to the net rope skeleton. The multiple bristle ribs 3 are distributed in a comb-like pattern, so that the cross-section of the brush-like unit in the direction perpendicular to the axis of the net rope skeleton is semi-circular.

[0049] This application embodiment utilizes a half-width directional brush-like structure of grass bundles, a rope mesh skeleton, and biodegradable seed ropes wound around the rope mesh skeleton to construct a half-width directional brush-like rope mesh sand barrier structure. This achieves an organic combination of windbreak and sand fixation functions with ecological restoration, improving the ecological environment of areas affected by wind and sand, reducing governance costs, and enhancing the sustainability and effectiveness of ecological governance. Specifically, by spirally winding multiple binding ropes around the seed rope as an axis, the structural strength of the rope mesh skeleton is strengthened, the seed rope is protected to prevent premature exposure of the seeds to the environment, and a high-porosity structure is formed, which facilitates water storage and promotes seed germination and growth.

[0050] In one implementation scheme, the diameter of the seed rope 2 and the fixing rope 4 is 2.5-3.5cm. The fixing rope 4 can be made of straw rope.

[0051] In one implementation scheme, such as Figure 2 and Figure 3As shown, the brush-like unit includes a bundle of grass, which is formed by the aggregation of multiple plant stems. The bundle consists of a first structural segment 51, a second structural segment 52, and a third structural segment 53 connected sequentially along its length. The second structural segment 52 is located in the middle of the bundle and is fixedly connected to the net rope skeleton 1. The first structural segment 51 and the third structural segment 53 are symmetrically arranged, and the plant stems therein are scattered to form the brush bristles 3.

[0052] The second structural segment 52 is bent into a ring and wraps around the net rope skeleton. The tail end of the first structural segment 51 contacts the left side of the net rope skeleton 1, and the head end extends to the upper right of the net rope skeleton 1; the head end of the third structural segment 53 contacts the right side of the net rope skeleton 1, and the tail end extends to the upper left of the net rope skeleton 1.

[0053] The plant stems can be made of rice straw or wheat straw, but are not limited to these. The length of the bristle ribs 3 can be 20-50cm. The spacing between adjacent bristle ribs 3 can be 5-15cm. In this way, the brush-like unit can have a three-dimensional sand-blocking and sand-fixing structure formed by multiple bristle ribs 3 arranged at a suitable density.

[0054] Among them, the multiple fixed ropes 4 are spirally wound around the seed rope 2 with a winding spacing of 8-20cm.

[0055] In this implementation, the grass bundles formed by multiple plant stems are segmented and fixedly connected to the net rope skeleton, which can make the brush-like units and the net rope skeleton structurally strong. The ring structure formed in the middle of the grass bundle wraps around the net rope skeleton, which can further strengthen the basic structural strength of the net rope sand barrier, forming multiple layers of protection for the seeds and preventing them from being sniffed and damaged by insects, rodents and other animals. At the same time, the ring structure also has a porous structure, which can absorb and store water, thus further improving the water storage capacity of the net rope skeleton. It forms a multi-layered water storage structure with the net rope skeleton and seed rope, which can slow down the rate of water loss.

[0056] In one implementation scheme, such as Figure 3 As shown, the semi-width directional brush-like rope sand barrier structure includes a straw curtain, which is woven from warp threads 6 and multiple bundles of straw as weft threads. The warp threads 6 intersect and connect with the second structural segment 52. Preferably, there are two or more warp threads 6 spaced apart from each other. The warp threads can be made of straw rope, plant vines, plant fiber threads, biodegradable synthetic fiber threads, etc.

[0057] Preferably, the grass bundle is further secured to the netting frame by biodegradable braided thread that passes between the plant stems, so that the multiple bristle ribs 3 maintain the comb-like distribution. Using the braided thread for shaping allows the bristle ribs formed by the grass bundles fixed to the netting frame to maintain their comb-like distribution for a long time, ensuring its wind and sand blocking ability. The biodegradable braided thread can be made of plant fibers, biodegradable synthetic fibers, etc.

[0058] In this embodiment, the porosity of the net rope skeleton 1 is 30%-60%, which ensures that the net rope skeleton has sufficient mechanical strength and good water absorption and storage performance.

[0059] In specific applications, the knotted rope 4, straw bundles, etc., can be coated with an environmentally friendly anti-mold agent or impregnated in an environmentally friendly anti-mold agent. The environmentally friendly anti-mold agent can be a 3%-5% sodium diacetate solution or white-rot fungus fermentation liquid, etc., and is not limited to these. This modification treatment can improve the durability of the material and ensure the long-term working performance of the rope-based sand barrier. Preferably, one or more of the knotted rope 4, straw bundles, seed ropes, etc., are soaked in an animal-repellent agent such as wood vinegar, MA crude oil, or MP crude oil, then dried, and finally coated with an environmentally friendly anti-mold agent.

[0060] Preferably, the seed rope 2 can also be bonded and fixed to the binding rope 4 with a biodegradable adhesive. This further enhances the connection stability between the seed rope and the frame, preventing the seed rope from falling off during transportation, laying, and wind and sand impact. The biodegradable adhesive mainly uses natural adhesives or biodegradable synthetic adhesives, such as starch adhesives, gelatin, plant gums (such as gum arabic, xanthan gum, peach gum, etc.), chitosan, hyaluronic acid, sodium alginate, collagen, various types of cellulose or their salts, etc. Starch adhesives (such as modified pregelatinized starch) are preferred, as they not only have strong adhesion but can also form hydrogels, improving the water retention performance of the net rope sand barrier.

[0061] In some embodiments, such as Figures 4 to 6 As shown, the seed rope 2 includes multiple desert plant seeds 21, a core rope 22, and a shell layer 23. The core rope is formed by winding and twisting hemp fabric, and multiple desert plant seeds are wrapped inside the core rope. The core rope is impregnated with an insect repellent. The shell layer is wrapped around the core rope, and starch-grafted acrylic copolymer absorbent material 24 is filled between the shell layer and the core rope. The shell layer is formed by winding hemp fabric.

[0062] In this implementation, using hemp fabric to form the core rope and shell layer can give the seed rope good tensile strength and flexibility, while also giving it a porous structure that facilitates water absorption and storage. Impregnating the core rope with an insect repellent can effectively repel animals, and this method can also prevent the insect repellent from evaporating or being lost too quickly, achieving a long-term insect repellent effect. Then, by filling it with absorbent material, the core rope and shell layer can be bonded together, improving the structural strength of the seed rope. Utilizing the water-absorbing properties of this material to form a hydrogel, the water storage performance of the seed rope is enhanced.

[0063] This application also provides a method for manufacturing the above-mentioned half-width directional brush-like net rope sand barrier structure, such as... Figure 9 As shown, the method includes the following steps:

[0064] Multiple seeds of desert plants are placed sequentially on the hemp fabric along its length. The hemp fabric is then rolled and twisted, soaked in an insect repellent, and then dried to obtain the core rope.

[0065] Place the core rope on the hemp fabric, and evenly spread starch-grafted acrylic copolymer absorbent material on the hemp fabric. Then, wrap the hemp fabric around the core rope to form a seed rope.

[0066] Using the seed rope as the axis, multiple knotted ropes are spirally wound around the seed rope to form a net rope skeleton;

[0067] A straw mat is provided, the straw mat being woven from warp threads and a plurality of bundles of straw as weft threads;

[0068] The net rope frame is placed in the center of the straw mat, and the axis of the net rope frame is perpendicular to each straw bundle. The straw bundle is composed of a first structural segment, a second structural segment, and a third structural segment connected in sequence along the length direction. The second structural segment is located in the middle of the straw bundle, and the first and third structural segments are symmetrically arranged.

[0069] The second structural segment of each bundle of grass is bent into a loop and wrapped around the netting frame. The first structural segment extends to the upper right side of the netting frame, and the third structural segment extends to the upper left side of the netting frame. Then, the plant stems in the first and third structural segments are broken apart to form multiple brush ribs. These brush ribs are then inserted between the broken plant stems and sewn to the netting frame to fix them in place. This ensures that the multiple brush ribs are stably maintained in a comb-like distribution, thus obtaining a brush-like unit.

[0070] Furthermore, after a brush-shaped unit is completed, it can be pushed along the length of the rope skeleton to fit closely with other brush-shaped units, thereby making the half-width directional brush-shaped rope sand barrier structure more robust and compact.

[0071] For example, a method for manufacturing a half-width directional brush-like rope sand barrier structure specifically includes the following steps:

[0072] S1. Select natural forage materials such as wheat straw, rice straw, and reeds that are free from mold and damage. Then, comb the selected natural forage materials neatly, remove impurities, and make them into bundles. Next, select straw ropes with a diameter of 2.5-3.5cm as binding ropes. The straw ropes can be made from rice straw and can be modified by spraying with anti-mold agents, UV protectants, etc. Preferably, they are first thoroughly impregnated with an insect repellent and then dried before being sprayed with an anti-mold agent.

[0073] S2. Place multiple seeds of desert plants sequentially along the length of a hemp fabric. Then, roll and twist the hemp fabric, soak it in an insect repellent, and dry it to obtain a core rope. Place the core rope on the hemp fabric, and evenly spread a starch-grafted acrylic copolymer absorbent material on the fabric. Then, roll the hemp fabric to wrap the core rope, forming a seed rope. The desert plant seeds can be selected from drought-resistant desert plants such as sea buckthorn, saxaul, artemisia, and jujube, with a preferred purity ≥95% and germination rate ≥80%. The distribution density of desert plant seeds within the seed rope can be set to 5-15 seeds / 10cm, ensuring that the seeds are distributed without accumulation or gaps.

[0074] After the seed ropes are made, the seeds can be randomly selected for a germination test (cultivated for 7 days in an environment with a constant temperature of 25℃ and 12 hours of light per day). The germination rate must be ≥80%. Batches that do not meet the standard must have their seed ropes replaced.

[0075] Furthermore, the seed rope was placed in an environment of 25°C and 70% humidity for 7 days to test its biodegradability. The results showed that the seed rope showed initial signs of degradation under these conditions.

[0076] S3. Using a seed rope as the axis, spirally wind two binding ropes around the seed rope to form a net rope skeleton. The spiral winding spacing should be controlled at 8-20cm. During the winding process, keep the binding ropes and seed ropes at a moderate tension to avoid damaging the net rope skeleton due to excessive tightness or causing the binding ropes and seed ropes to detach due to excessive looseness. The length of each seed rope segment should be consistent with the length of the net rope skeleton, for example, it can be set to 9-11m. Preferably, the porosity of the net rope skeleton should be controlled at 30%-60%. Furthermore, a small amount of biodegradable special adhesive can be applied to the contact point between the binding rope and the seed rope to enhance the bonding stability. The amount of adhesive should be such that it does not penetrate into the seeds.

[0077] S4. Place the middle section of the grass bundle (i.e., the second section mentioned above) on the netting frame, ensuring they are perpendicular. Then, bend the second structural section of the grass bundle into a loop and wrap it around the netting frame. Extend the first structural section towards the upper right side of the netting frame, and the third structural section towards the upper left side. Break up the plant stems in the first and third structural sections to form multiple brush ribs, maintaining these ribs in a stable, comb-like distribution. Control the spacing between the brush ribs to 5-15cm and the length of each brush rib to 20-50cm, thus completing the fabrication of one brush-like unit. Repeat these steps to create multiple brush-like units. Preferably, adjacent brush-like units are placed close together.

[0078] In some cases, biodegradable braided thread can be threaded through the loosened plant stems to sew and secure the straw bundles to the rope framework. The biodegradable braided thread can be made from plant fibers, biodegradable synthetic fibers, or even rice straw stems. Sewing methods can include a cross-stitch, with 5-6 stitches at each point followed by a knot.

[0079] Furthermore, the ends of the net rope frame can be reinforced with natural fiber binding rope, wrapped 5-8 times and knotted to prevent the ends from loosening during transportation.

[0080] After the half-width directional brushed net rope sand barrier structure is completed, its appearance can be inspected to check for issues such as broken straw, damaged seed ropes, or exposed seeds. Any substandard appearance must be repaired. Next, a simulated windy and sandy environment can be used, with a blower blowing the half-width directional brushed net rope sand barrier structure at a wind speed of 5 m / s to observe its structural stability. The results show that the sand barrier structure exhibits no significant deformation and the seed ropes do not detach.

[0081] In addition, a horizontal tension of 50N was applied to the middle of the sand barrier using a tension gauge for 30 seconds. The results showed that the seed rope did not fall off and the frame remained basically unchanged.

[0082] Furthermore, in this embodiment of the application, the half-width directional brush-shaped net rope sand barrier structure (hereinafter referred to as net rope) is also used to construct wind and sand prevention facilities.

[0083] For example, please refer to Figure 8 First, a detailed survey of the terrain, wind direction, and soil conditions of the area requiring windbreak, sand fixation, and ecological restoration should be conducted. Based on the survey results, the placement of the netting should be planned at 1-2 meter intervals. The bottom of the netting should then be laid smoothly on the ground, and secured with branches or stakes to ensure a firm grip. Adjacent netting sections can be connected using natural fiber ropes to ensure a continuous protective system.

[0084] For example, the netting ropes of this application embodiment can also be used in sand control and ecological restoration of large-scale photovoltaic power plants. For instance, the netting ropes can be laid around the perimeter of the photovoltaic power plant, in the edge areas, under the photovoltaic panels, and between the panels to form 1m×1m or 1.5m×1.5m sand-fixing grids, simultaneously completing the tasks of windbreak and sand fixation and ecological restoration of the large-scale power plant. For areas where photovoltaic panels have not yet been installed, the netting ropes can be laid first. After the netting ropes are laid and fixed, the photovoltaic panels can be installed, forming a collaborative protection system between the photovoltaic panel array and the netting ropes. The mounting brackets for the photovoltaic panels can be appropriately increased by 5-10 cm to leave sufficient space above the netting ropes for wind and sand to pass through, reducing the direct impact of wind and sand on the photovoltaic panels. For existing large-scale photovoltaic power plants, when installing the netting ropes, care must be taken to avoid the cables and junction boxes of the photovoltaic panels. A segmented construction method should be adopted to ensure that the power generation of the photovoltaic power station is not affected during the construction process.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.

Using the seed rope as the axis, multiple knotted ropes are spirally wound around the seed rope to form a net rope skeleton; A straw mat is provided, the straw mat being woven from warp threads and a plurality of bundles of straw as weft threads; The net rope frame is placed in the center of the straw mat, and the axis of the net rope frame is perpendicular to each straw bundle. The straw bundle is composed of a first structural segment, a second structural segment, and a third structural segment connected in sequence along the length direction. The second structural segment is located in the middle of the straw bundle, and the first and third structural segments are symmetrically arranged. The second structural segment of each grass bundle is bent into a loop and wrapped around the netting frame. The first structural segment extends to the upper right side of the netting frame, and the third structural segment extends to the upper left side of the netting frame. Then, the plant stems in the first and third structural segments are broken apart to form multiple brush ribs. Biodegradable braided thread is then inserted between the broken plant stems to sew and fix the grass bundle to the netting frame, so that the multiple brush ribs are stably maintained in a comb-like distribution, thereby obtaining a brush-shaped unit.

10. The use of the semi-width directional brush-shaped net rope sand barrier structure according to any one of claims 1-8 in the construction of facilities for sand control and ecological restoration of photovoltaic power plants.
