Description

Technical Field

[0001] This utility model relates to the technical field of windbreak and sand-fixing devices, specifically to a windbreak and sand-fixing device for ecological vegetation restoration. Background Technology

[0002] In ecological restoration, windbreak and sand fixation are crucial. Traditional windbreak and sand fixation devices include mechanical sand barriers, barriers made of firewood and branches, and metal and plastic sand-fixing nets.

[0003] On the one hand, commonly used metal and plastic materials are non-biodegradable, and when left in sandy areas, they damage soil structure, pollute the environment, and hinder sustainable ecological development. On the other hand, traditional devices often focus on sand fixation but are poorly integrated with vegetation restoration. Even with planting designs, water and fertilizer retention and the creation of a suitable environment for seed growth are insufficient, resulting in poor vegetation restoration, difficulty in forming a stable ecosystem, and inability to achieve long-term sand fixation.

[0004] Therefore, there is an urgent need for an environmentally friendly and long-lasting device that can balance sand fixation and ecological restoration. This device should use biodegradable materials to reduce environmental impact while effectively promoting vegetation recovery and driving the self-repair of the sandy land ecosystem.

[0008] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a windbreak and sand-fixing device for ecological vegetation restoration, comprising a support frame, a sand-fixing net, and a planting container. The support frame has a grid-like structure with multiple square units inside. The sand-fixing net covers the surface of the square units of the support frame and is fixed by adhesive. The planting container is suspended inside the square units of the support frame, and is filled with water-retaining substrate and plant seeds. The bottom of the planting container has water-permeable holes, and the side walls are connected to the support frame by hooks. The bottom of the support frame has an anchoring structure for fixing the support frame in the sand. It also includes a guide plate, which is installed at an angle of 30-60° to the windward side of the top of the support frame to reduce wind speed and guide wind direction.

[0009] Furthermore, the support frame is made of bamboo, wood, straw composite materials, or polylactic acid-based biodegradable plastic.

[0010] Furthermore, the surface of the sand-fixing net is coated with a biological adhesive layer, the adhesive being a starch-based or cellulose-based material, used to adsorb sand particles and promote the bonding between the sand-fixing net and the sandy land.

[0011] Furthermore, the planting container is made of biodegradable pulp or PLA plastic, and its water-retaining substrate is a mixture of water-absorbing resin, humus and sand in a ratio of 1:2:3. The plant seeds are local drought-resistant shrubs or herbaceous plants.

[0012] Furthermore, the anchoring structure uses ground nails or anchor rods. The ground nails are made of conical bamboo or wood, and the anchor rods are made of spiral-shaped biodegradable plastic rods.

[0026] Combined with appendix Figure 1 To be continued Figure 4 A windbreak and sand-fixing device for ecological vegetation restoration includes a support frame 1, a sand-fixing net 2, and a planting container 3. The support frame 1 has a grid-like structure with multiple square units inside. The sand-fixing net 2 covers the surface of the square units of the support frame 1 and is fixed with adhesive. The planting container 3 is suspended inside the square units of the support frame 1 and is filled with water-retaining substrate and plant seeds. The bottom of the planting container 3 has water-permeable holes 4, and the side walls are connected to the support frame 1 by hooks 5. The bottom of the support frame 1 has an anchoring structure 5 for fixing the support frame 1 in the sand. It also includes a guide plate 6, which is installed at an angle of 30-60° to the windward side of the top of the support frame 1 to reduce wind speed and guide wind direction.

[0027] The supporting frame 1 is made of bamboo and wood, straw composite materials, or polylactic acid-based biodegradable plastic. The surface of the sand-fixing net 2 is coated with a bio-adhesive layer, the adhesive being starch-based or cellulose-based materials, used to absorb sand particles and promote the bonding between the sand-fixing net 2 and the sandy land. The planting container 3 is made of biodegradable pulp or PLA plastic, and its water-retaining substrate is a mixture of water-absorbing resin, humus, and sand in a 1:2:3 ratio. The plant seeds are local drought-resistant shrubs or herbaceous plants. The anchoring structure 5 uses ground nails or anchor rods; the ground nails are made of conical bamboo and wood, and the anchor rods are spiral-shaped biodegradable plastic rods.

[0028] The working principle of this invention is as follows: a stable structure is constructed through the supporting frame 1, and sand-fixing net 2 initially blocks sand particles; the guide plate 6 changes the airflow direction and reduces wind speed, thereby reducing the impact of wind and sand on the device and the sandy land; the water-retaining substrate inside the planting container 3 maintains moisture, providing a suitable environment for plant seeds to germinate and grow, and vegetation growth further stabilizes the sand; the anchoring structure 5 ensures the stability of the entire device. All components work together to achieve windbreak and sand fixation as well as ecological vegetation restoration.

[0029] The working process of this utility model is as follows:

[0030] 1. Installation of the device: Place the support frame 1 at the predetermined position in the sand and use the anchoring structure 5. If it is a cone-shaped bamboo or wood nail, drive it directly into the sand; if it is a spiral biodegradable plastic rod, screw it into the sand to make the support frame 1 firmly fixed in the sand.

[0031] 2. Planting container placement: Fill the planting container 3 with a water-retaining substrate made of water-absorbing resin, humus and sand in a ratio of 1:2:3, and sow local drought-resistant shrubs or herb seeds. Then, suspend the planting container 3 in the square unit of the support frame 1 through the hooks 5 on the side wall.

[0032] 3. Laying sand-fixing net: Unfold the sand-fixing net 2 and cover the surface of the square unit of the supporting frame 1. Fix it with adhesive to initially block sand particles.

[0033] 4. Function of the deflector: The deflector 6, which is installed at an angle of 30-60° with the horizontal plane on the windward side of the top of the support frame 1, can effectively reduce the wind speed and guide the wind direction.

[0034] 5. Wind and sand protection and vegetation restoration: When wind and sand strike, the guide plate 6 acts first to change the direction of wind and sand flow and reduce wind speed; the sand-fixing net 2 blocks some sand particles; the water-permeable holes 4 at the bottom of the planting container 3 allow excess water to flow out during rainfall, and the water-retaining substrate stores water for plant seed germination and growth. As the plants grow and take root, they penetrate deep into the sand through the water-permeable holes 4, further enhancing the sand-fixing capacity and realizing ecological vegetation restoration.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
