Description

Technical Field

[0001] This utility model relates to the field of greening net technology, specifically a garden greening slope greening net for windbreak and soil stabilization. Background Technology

[0002] Green slope netting is a mesh material laid on slopes to assist plant growth and prevent soil erosion. It is widely used in highway slopes, railway slopes, mountain parks, ecological restoration areas and other scenarios. The netting can form a stable structure on the slope, help fix seeds and retain moisture, and combine with the root system during plant growth, thereby enhancing the vegetation coverage and overall stability of the slope and helping to achieve the goals of slope greening, ecological restoration and environmental beautification.

[0003] Existing greening nets for slopes typically use materials such as plastic netting, coconut fiber mats, or wire mesh, laid on the slope surface to cover the soil and aid plant growth, aiming to achieve slope greening and soil and water conservation. However, in practical applications, they often face the impact of sudden strong winds or continuous gusts. Due to the lightweight nature and simple fixing methods of some greening nets, they lack good wind-resistant structural support, making them easily lifted or torn by strong winds. This results in exposed soil, damaged vegetation, and even seeds being blown away, severely damaging the greening effect and soil and water conservation function of the slope. Especially in areas with strong winds or in the early stages when newly sown vegetation has not yet formed a stable cover, once the greening net is damaged, the ecological restoration of the entire slope will be hindered, thus affecting the overall stability of the slope structure. Therefore, existing technologies have significant shortcomings in dealing with sudden strong winds, and there is an urgent need to improve the wind resistance stability of greening nets to enhance their adaptability to harsh climatic conditions and their long-term reliability.

[0004] In view of this, we propose a windbreak and soil-stabilizing landscaping slope greening net. Utility Model Content

[0005] The purpose of this utility model is to provide a windproof and soil-stabilizing garden greening slope greening net, which solves the problem that existing greening slope greening nets are easily blown away or damaged when encountering sudden strong winds.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 5As shown, this utility model provides a technical solution: a windbreak and soil-stabilizing garden slope greening net, including a greening net 1 for windbreak and soil stabilization. One end of the greening net 1 is fixedly connected to a side connecting strip 2, and the other end of the greening net 1 is provided with a connecting shaft 4. A winding mechanism 5 is provided on the connecting shaft 4. The winding mechanism 5 includes: a hollow connecting strip 51, the inner wall of which is rotatably connected to the connecting shaft 4. A hollow disk 52 is fixedly connected to the bottom of the connecting shaft 4. The bottom of the hollow disk 52... A drive shaft 54 ​​is rotatably connected. A spiral spring 53 is installed between the drive shaft 54 ​​and the hollow disk 52. One end of the spiral spring 53 is fixedly connected to the drive shaft 54, and the other end is fixedly connected to the inner wall of the hollow disk 52. A connecting piece 56 is fixedly connected to the hollow connecting strip 51. A spiral spring 55 is installed between the connecting piece 56 and the drive shaft 54. One end of the spiral spring 55 is fixedly connected to the outer wall of the drive shaft 54, and the other end is fixedly connected to the outer wall of the drive shaft 52. One end is fixedly connected to the inner wall of the connecting piece 56. The elastic coefficient of the first spiral spring 53 is lower than that of the second spiral spring 55. One end of the greening net 1 is connected to the winding mechanism 5 through the connecting shaft 4. When the greening net 1 is subjected to strong wind during use, the wind will cause the connecting shaft 4 to rotate. The hollow connecting strip 51 allows the connecting shaft 4 to rotate relative to it. It is connected to the drive shaft 54 ​​through the first spiral spring 53. The first spiral spring 53 is the first buffer spring. When stretched, it can store wind energy and play a preliminary buffering role. More importantly, the drive shaft 54 ​​is also connected to the connecting piece 56 through the second spiral spring 55. The second spiral spring 55 has a stronger elastic force, forming a secondary buffer structure. In the structure of the greening net 1 of the green slope, the key lies in the two spiral springs set in series: the first spiral spring 53 is installed between the drive shaft 54 ​​and the hollow disc 52 and has a smaller elastic force; the second spiral spring 55 is installed between the drive shaft 54 ​​and the connecting piece 56 and has a larger elastic force. These two springs, together with connecting shaft 4 and drive shaft 54, form a rotary buffer system with nonlinear stiffness segmentation characteristics. When external wind force acts on the green netting 1, causing tension, connecting shaft 4 drives the entire winding mechanism 5 to rotate, with the spiral springs responding sequentially to achieve gradual buffering. When the wind force is too strong, drive shaft 54 ​​rotates slowly under the constraint of the two-stage spiral springs, reducing the risk of instantaneous breakage or tearing of the green netting 1. After the wind force disappears, the two spiral springs 53 and 55 will... The retraction causes the drive shaft 54 ​​and connecting shaft 4 to rotate in opposite directions, rewinding the green net 1 and further enhancing the structural tension and stability. Through this dual-stage buffer design of "volute spring energy storage + automatic return", the green net 1 can flexibly expand and contract even in the event of a sudden strong wind, avoiding being blown away or damaged by the wind. A locking mechanism 6 is provided on the hollow connecting strip 51. The locking mechanism 6 is used to position and lock the drive shaft 54 ​​after the green net 1 is rewound, preventing the green net 1 from accidentally loosening during transportation or when not in use.

[0026] Two fixing ears 3 are symmetrically arranged on the side connecting strip 2. Two fixing ears 3 are symmetrically fixedly connected on the hollow connecting strip 51. The hollow disk 52 is rotatably connected to the inner wall of the hollow connecting strip 51, so that the hollow disk 52 rotates stably. The top of the connecting shaft 4 is provided with an internal hexagonal groove. The connecting shaft 4 can be rotated with a hexagonal wrench to reel in the green net 1. At this time, both the first spiral spring 53 and the second spiral spring 55 are rotated and stored.

[0027] The locking mechanism 6 includes a rigid block 61, which is fixedly connected to the inner wall of the hollow connecting strip 51. A spring 62 is provided on the rigid block 61, with one end of the spring 62 fixedly connected to the rigid block 61 and the other end of the spring 62 fixedly connected to a magnetic positioning block 63. A movable rod 64 is fixedly connected to the outer wall of the magnetic positioning block 63, and the movable rod 64 is slidably connected to the inner wall of the rigid block 61. A gear 65 is fixedly connected to the outer wall of the drive shaft 54, and a magnetic element 66 is fixedly connected to the bottom of the rigid block 61. Before the green net 1 is rolled up, the movable rod 64 is pulled to move the magnetic positioning block 63 toward the magnetic element 66. At this time, the magnetic element 66 is magnetically fixed to the magnetic positioning block 63. After the green net 1 is rolled up, the movable rod 64 is pushed to move the magnetic element 66. The magnetic positioning block 63 moves towards the gear component 65. At this time, under the elastic action of the spring 62, the magnetic positioning block 63 engages with the gear component 65, thereby engaging the drive shaft 54. This prevents the greening net 1 from automatically loosening and ensures it does not come loose during transportation. The greening net 1 is made of high-strength polyester material and fiberglass, which has tear-resistant properties. A needle roller bearing is provided between the connecting shaft 4 and the drive shaft 54 ​​to reduce rotational friction. The fixing ear 3 adopts a double screw hole structure and is fixed to the slope protection surface with expansion bolts. The hollow connecting strip 51 is equipped with a dustproof sealing ring to prevent mud and sand from entering the internal structure. The magnetic positioning block 63 is a permanent magnet and is equipped with a soft silicone protective layer to prevent wear. The edges of the greening net 1 are equipped with thickened edging, and tensile fiber ropes are provided inside the edging to improve tear resistance.

[0028] In use, the greening net for windbreak and soil stabilization of landscaping slopes of this utility model is connected at one end of the greening net 1 to the winding mechanism 5 via a connecting shaft 4. When the greening net 1 is subjected to strong wind during use, the wind will cause the connecting shaft 4 to rotate. The hollow connecting strip 51 allows the connecting shaft 4 to rotate relative to it, and is connected to the drive shaft 54 ​​via a spiral spring 53. The spiral spring 53 is the first buffer spring, which can store wind energy when stretched, playing a preliminary buffering role. More importantly, the drive shaft 54 ​​is also connected to the connecting plate 56 via a spiral spring 55. The spiral spring 55 has a stronger elasticity, forming a secondary buffer structure. In the structure of this greening net for slopes, the key lies in the two spiral springs arranged in series: spiral spring 53: installed between the drive shaft 54 ​​and the hollow disc 52, with a smaller elasticity; spiral spring 55: installed between the drive shaft 54 ​​and the connecting plate 56, with a larger elasticity. These two springs, together with the connecting shaft 4 and the drive shaft 54, form a rotary buffer system with nonlinear stiffness segmentation characteristics. When external wind force acts on the green net 1, causing tension, the connecting shaft 4 drives the entire winding mechanism 5 to start rotating, and the spiral springs respond sequentially to achieve gradual buffering. When the wind force is too strong, the drive shaft 54 ​​rotates slowly under the restriction of the two-stage spiral springs, reducing the risk of instantaneous breakage or tearing of the green net. After the wind force disappears, the two spiral springs 53 and 55 will contract, driving the drive shaft 54 ​​and the connecting shaft 4 to rotate in opposite directions, rewinding the green net 1 and further enhancing the structural tension and stability. Through this dual-stage buffer design of "spiral spring energy storage + automatic return", even in the event of a sudden strong wind, the green net 1 can flexibly expand and contract, avoiding damage from the wind.

[0029] Before the greening net 1 is rolled up, the movable rod 64 is pulled to move the magnetic positioning block 63 toward the magnetic suction component 66. At this time, the magnetic suction component 66 and the magnetic positioning block 63 are magnetically fixed together. After the greening net 1 is rolled up, the movable rod 64 is pushed to move the magnetic positioning block 63 toward the gear component 65. At this time, under the elastic action of the spring 62, the magnetic positioning block 63 and the gear component 65 are engaged, which engages the drive shaft 54 ​​and prevents the greening net 1 from automatically loosening and from coming loose during transportation.
