Description

Technical Field

[0001] This utility model relates to the field of windbreak technology, specifically a windbreak for high-altitude afforestation suitable for special climates. Background Technology

[0002] Afforestation work in high-altitude areas faces extremely unique and harsh climatic conditions, particularly in the Qinghai-Tibet Plateau and the Yunnan-Guizhou Plateau. These areas not only experience strong winds but also unpredictable wind directions. Strong winds can directly impact newly planted seedlings, causing them to lodging and potentially blowing away the soil around the roots, exposing the roots and severely damaging their growth foundation, thus significantly reducing their survival rate.

[0003] Traditional windbreaks mostly use a fixed structure design, which cannot flexibly adjust the ventilation volume according to the actual wind force. When the wind is too strong, the fixed structure of the barrier is unable to effectively disperse the wind force, and the excessive wind load makes it easy to be blown down by strong winds. Not only does it lose its windproof function, but it may also cause secondary damage to the surrounding seedlings. When the wind is weak, the fixed barrier will excessively obstruct the air circulation, resulting in poor air exchange in the afforestation area, affecting the supply of carbon dioxide needed for seedling photosynthesis. It may also cause an imbalance in environmental parameters such as humidity and temperature in the area, destroying the suitable growth environment for seedlings.

[0004] Existing windbreaks are insufficient to simultaneously meet the multiple requirements of resisting strong winds and providing adjustable ventilation, thus failing to provide stable, continuous, and effective wind protection for afforestation in plateau areas. This severely restricts the development of afforestation work and the improvement of afforestation results in plateau regions. Utility Model Content

[0007] As a further description of the above technical solution:

[0008] A subsequent exhaust unit is provided on one side of the preliminary exhaust unit. The subsequent exhaust unit includes a connecting plate, a connecting slide rod is connected to the lower side of the connecting plate, a first piston is connected to one end of the connecting slide rod, a second spring is connected to one end of the first piston, a connecting block is connected to one end of the second spring, a connecting pipe is connected to the outer side of the connecting block, a second piston is connected to one end of the connecting pipe, a first adjusting vent plate is provided on one side of the second piston, and a second adjusting vent plate is provided on the inner side of the barrier body.

[0009] As a further description of the above technical solution:

[0010] The guide rod is slidably connected to the barrier body through guide balls. Multiple sets of guide balls are evenly distributed on both sides of the guide rod. The rack is fixedly installed at the end of the guide rod away from the wind-blown push plate. Two sets of guide rods are symmetrically arranged on both sides of the wind guide plate.

[0011] As a further description of the above technical solution:

[0012] The two ends of the spring are respectively fixedly connected to the inner side of the connecting shell and the end of the rack away from the guide rod. The rack is slidably connected to the inner side of the connecting shell, and the connecting shell is fixedly set inside the barrier body.

[0013] As a further description of the above technical solution:

[0014] The gear is connected to the middle position of the air guide plate via a connecting shaft. The gear is rotatably connected to the inner side of the barrier body via the connecting shaft. The air guide plate is rotatably slidable against the inner side of the barrier body. The rotating shaft is rotatably connected to one side of the air guide plate.

[0015] As a further description of the above technical solution:

[0016] The rotating shaft is rotatably and slidably disposed on the upper side of the connecting plate, the upper end of the connecting slide rod is fixedly disposed at the middle position of the lower side of the connecting plate, the first piston is fixedly disposed at the lower end of the connecting slide rod, the two ends of the second spring are respectively fixedly connected to the lower side of the first piston and the upper side of the connecting block, and the connecting block is fixedly disposed on the inner side of the connecting tube.

[0017] As a further description of the above technical solution:

[0019] This utility model has the following beneficial effects:

[0020] 1. In the initial ventilation unit, the guide rod and guide ball reduce friction and ensure stable sliding of the rack, which drives the gear and wind guide plate to adjust the angle and initially disperse the wind force. The subsequent ventilation unit uses air pressure transmission to drive the first regulating air outlet plate to slide, adjust the overlapping area of ​​the ventilation holes, and control the wind throughput. This effectively solves the problem that traditional fixed barriers cannot adjust the ventilation volume according to the wind force. It can resist strong winds to prevent seedlings from falling over, and ensure air circulation, providing a suitable growth environment for seedlings and improving the survival rate of afforestation.

[0021] 2. The spring in the initial ventilation unit can drive the rack to automatically reset, ensuring that the wind guide plate is adjusted in time when the wind force changes. The two sets of connecting pipes of the subsequent ventilation unit are symmetrically arranged to ensure that the first adjusting air outlet plate slides smoothly and avoids structural jamming due to uneven force. The barrier body adopts an aluminum alloy frame, which is lightweight and strong, making it easy to install in complex terrain on the plateau. At the same time, the inner sliding rail design ensures smooth movement of each sliding component. This device effectively solves the impact of strong winds on afforestation on the plateau, as well as the problems of traditional barriers being easy to damage and difficult to adjust.

[0033] Example 1:

[0034] like Figures 1 to 6 As shown in the figure, this embodiment provides a windbreak barrier for plateau afforestation suitable for special climates, including a barrier body 3. A preliminary ventilation unit 1 is provided on one side of the barrier body 3. The preliminary ventilation unit 1 includes a wind-blowing pusher plate 11. A guide rod 12 is connected to one side of the wind-blowing pusher plate 11. A guide ball 13 is connected to one side of the guide rod 12. A rack 14 is connected to one end of the guide ball 13. A spring 15 is connected to one end of the rack 14. A connecting shell 16 is connected to one end of the spring 15. A gear 17 is provided on the lower side of the rack 14. A wind guide plate 18 is connected to one side of the gear 17. A rotating shaft 19 is connected to the wind guide plate 18.

[0035] In this embodiment, the initial ventilation unit 1, the subsequent ventilation unit 2, and the barrier body 3 constitute a windbreak barrier for plateau afforestation suitable for special climates, as described in this application.

[0036] Understandable, Figure 1 The diagram only schematically illustrates some of the components included in the windbreak; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, windbreaks can also include, compared to Figure 1 More or fewer parts.

[0037] It should also be understood that the wind barriers were all purchased from the market and are common knowledge in this field. They are only used and not modified, so the control methods and circuit connections will not be described in detail.

[0038] Furthermore, in this embodiment, the guide rod 12 is a cylindrical structure made of Q235 low-carbon steel, and the guide ball 13 is spherical made of bearing steel. Four balls are set in each group. The two groups of guide rods 12 are located on the left and right sides of the wind guide plate 18, respectively. When the strong wind at high altitude acts on the wind-blown push plate 11, the wind-blown push plate 11 pushes the guide rod 12 to move, and the guide ball 13 rolls in the slide rail of the barrier body 3, reducing the frictional resistance when the guide rod 12 moves, so that the rack 14 can slide smoothly.

[0039] Specifically, a subsequent exhaust unit 2 is provided on one side of the initial exhaust unit 1. The subsequent exhaust unit 2 includes a connecting plate 21. A connecting slide rod 22 is connected to the lower side of the connecting plate 21. A first piston 23 is connected to one end of the connecting slide rod 22. A second spring 24 is connected to one end of the first piston 23. A connecting block 25 is connected to one end of the second spring 24. A connecting pipe 26 is connected to the outer side of the connecting block 25. A second piston 27 is connected to one end of the connecting pipe 26. A first adjusting vent plate 28 is provided on one side of the second piston 27. A second adjusting vent plate 29 is provided on the inner side of the barrier body 3.

[0040] In this embodiment, spring 15 is a cylindrical helical spring, and connecting shell 16 is a cuboid structure made of aluminum alloy. It is fixed to the inner side of the barrier body 3 near the top and is connected to the inner sidewall of the barrier body 3 by bolts. Each set of preliminary exhaust units corresponds to two connecting shells, which are located on both sides of the rack 14. When the rack 14 slides, it compresses spring 15, and spring 15 generates a reverse elastic force. When the wind force decreases, spring 15 pushes the rack 14 to reset, driving gear 17 to rotate in the opposite direction.

[0041] Specifically, the guide rod 12 is slidably connected to the barrier body 3 through guide balls 13. Multiple sets of guide balls 13 are evenly distributed on both sides of the guide rod 12. The rack 14 is fixedly installed at the end of the guide rod 12 away from the wind-blown push plate 11. Two sets of guide rods 12 are symmetrically arranged on both sides of the air guide plate 18.

[0042] In a preferred embodiment, gear 17 is a spur gear made of 45# steel, the connecting shaft is made of stainless steel, the air guide plate 18 is a rectangular thin plate made of fiberglass with anti-corrosion treatment on the surface, and the rotating shaft 19 is cylindrical made of stainless steel and located in the middle of one side edge of the air guide plate 18. When the rack 14 slides, it meshes with gear 17, driving gear 17 to rotate around the connecting shaft. When gear 17 rotates, it drives air guide plate 18 to rotate around rotating shaft 19 through the connecting shaft, thus adjusting the tilt angle of air guide plate 18.

[0043] Example 2:

[0044] Specifically, the two ends of the spring 15 are fixedly connected to the inner side of the connecting shell 16 and the end of the rack 14 away from the guide rod 12, respectively. The rack 14 is slidably connected to the inner side of the connecting shell 16, and the connecting shell 16 is fixedly disposed on the inner side of the barrier body 3.

[0045] In this embodiment, the connecting slide rod 22 is cylindrical and made of stainless steel; the first piston 23 is circular and made of nitrile rubber, with a diameter consistent with the inner diameter of the connecting pipe 26; the connecting block 25 is cylindrical and made of aluminum alloy, and is fixed in the middle of the inner side of the connecting pipe 26; the connecting pipe 26 is a cylindrical hollow tube made of stainless steel; the two sets of connecting pipes are located on the left and right sides of the first adjusting air vent plate 28, respectively; when the air guide plate 18 rotates, it drives the rotating shaft 19 to move; the rotating shaft 19 pushes the connecting plate 21 to move up and down; the connecting plate 21 drives the connecting slide rod 22 and the first piston 23 to slide up and down; the first piston 23 compresses or stretches the second spring 24, and at the same time changes the air pressure in the connecting pipe 26; the change in air pressure pushes the second piston 27 to slide.

[0046] Specifically, the middle position of the gear 17 is connected to the middle position of the air guide plate 18 via a connecting shaft. The gear 17 is rotatably connected to the inner side of the barrier body 3 via the connecting shaft. The air guide plate 18 is fitted and rotatably slids against the inner side of the barrier body 3. The rotating shaft 19 is rotatably connected to one side of the air guide plate 18.

[0047] With this configuration, both the first regulating vent plate 28 and the second regulating vent plate 29 are rectangular thin plates made of fiberglass, with circular vent holes. The first regulating vent plate 28 is located to the right of the second regulating vent plate 29, and the two are tightly fitted together. The air guide plate 18 is located above the two sets of vent plates. The barrier body 3 is a cuboid frame structure made of aluminum alloy, with slide rails on the inner side for the first regulating vent plate 28 and the guide rod 12 to slide.

[0048] Example 3:

[0049] Specifically, the rotating shaft 19 is rotatably and slidably disposed on the upper side of the connecting plate 21, the upper end of the connecting slide rod 22 is fixedly disposed at the middle position of the lower side of the connecting plate 21, the first piston 23 is fixedly disposed at the lower end of the connecting slide rod 22, the two ends of the second spring 24 are respectively fixedly connected to the lower side of the first piston 23 and the upper side of the connecting block 25, and the connecting block 25 is fixedly disposed on the inner side of the connecting tube 26.

[0050] When the second piston 27 slides, it drives the first adjusting air vent plate 28 to slide on the inner slide rail of the barrier body 3, changing the degree of overlap of the air vents on the first adjusting air vent plate 28 and the second adjusting air vent plate 29, thereby adjusting the air vent area.

[0051] Specifically, the second piston 27 is slidably connected to the end of the connecting pipe 26 away from the connecting block 25, the first adjusting air vent plate 28 is fixedly disposed on one side of the second piston 27, the first adjusting air vent plate 28 is slidably connected to the side of the second adjusting air vent plate 29 away from the wind blowing push plate 11, the first adjusting air vent plate 28 and the second adjusting air vent plate 29 are provided with ventilation holes, the air guide plate 18 is disposed on the upper side of the second adjusting air vent plate 29 and the first adjusting air vent plate 28, the first adjusting air vent plate 28 is slidably connected to the inner side of the barrier body 3, and the connecting pipe 26 is provided in two sets and symmetrically disposed on both sides of the first adjusting air vent plate 28.

[0052] In this embodiment, by adjusting the air permeability area, the wind throughput is controlled, further weakening the wind force while ensuring a certain amount of ventilation, avoiding excessive air pressure difference on both sides of the barrier that could lead to barrier damage, and adapting to complex wind conditions on the plateau.

[0053] It should be noted that the spring 15 of the initial ventilation unit 1 and the spring 24 of the subsequent ventilation unit 2 are both cylindrical helical compression springs conforming to the GB / T2089-2009 standard. The material is uniformly selected as 60Si2Mn spring steel (tensile strength ≥1275MPa, yield strength ≥1175MPa) to adapt to the day and night temperature difference of -30℃~50℃ at high altitudes and the fatigue resistance requirements. The surface is also hot-dip galvanized and passivated to resist wind and sand corrosion.

[0054] Among them, the spring-15 has a wire diameter of 2.5mm to 3mm, an outer diameter that is 1mm to 2mm smaller than the inner width of the connecting shell 16, a free height of 30mm to 40mm, an effective number of 6 to 7 turns, a stiffness of 8N / mm to 10N / mm, a working limit load of ≥150N, and the end face adopts a process of tight clamping at both ends without grinding, which is suitable for the sensitive deformation requirements of short stroke sliding of rack 14 and angle adjustment of air guide plate 18;

[0055] Spring 24 has a wire diameter of 4mm to 5mm, an outer diameter that is 2mm to 3mm smaller than the inner diameter of the connecting tube 26, a free height of 45mm to 55mm, an effective number of coils of 7 to 8, a stiffness of 12N / mm to 15N / mm, a working limit load of ≥250N, and the end face adopts a process of grinding both ends together (grinding length ≥3 / 4 turn, contact surface flatness ≤0.05mm), which is suitable for the precise force transmission requirements of linear sliding and pneumatic transmission of the first piston 23;

[0056] Spring 15 and Spring 24 are used to initially disperse wind force and subsequently adjust ventilation volume, respectively, to ensure stable operation of the device under high-altitude and strong wind conditions.

[0057] When in use, when strong winds from the plateau act on the wind-blown push plate 11 on one side of the barrier body 3, the wind-blown push plate 11 is pushed by the wind force, which drives the guide rod 12 connected to it to move. The guide balls 13 evenly distributed on both sides of the guide rod 12 roll in the slide rail of the barrier body 3, effectively reducing the frictional resistance during the sliding process of the guide rod 12, ensuring that the guide rod 12 stably and smoothly drives the rack 14 at the end to slide inside the connecting shell 16. When the rack 14 slides, it will compress the spring 15 connected to one end, and the spring 15 will generate a reverse elastic force to prepare for subsequent reset.

[0058] Because rack 14 meshes with gear 17 below, the sliding of rack 14 drives gear 17 to rotate around its connecting shaft inside the barrier body 3. The middle position of gear 17 is connected to wind guide plate 18 through the connecting shaft. When gear 17 rotates, it synchronously drives wind guide plate 18 to rotate around its rotating shaft 19 inside the barrier body 3, adjusting the tilt angle of wind guide plate 18. The change in the angle of wind guide plate 18 can initially guide and disperse strong winds, directing some of the wind force in a preset direction, achieving initial weakening of strong winds and preventing strong winds from directly impacting seedlings.

[0059] During the rotation of the air guide plate 18, its rotating shaft 19 slides on the connecting plate 21 of the subsequent exhaust unit 2, thereby pushing the connecting plate 21 to move up and down. The connecting slide rod 22, which is fixed at the middle position of the lower side of the connecting plate 21, moves synchronously with the connecting plate 21, causing the first piston 23 at the lower end of the connecting slide rod 22 to slide inside the connecting pipe 26. When the first piston 23 slides, it will compress or stretch the second spring 24 connected to one end. The elastic force generated by the second spring 24 can assist the subsequent components to reset. At the same time, the movement of the first piston 23 changes the air pressure inside the connecting pipe 26.

[0060] Changes in air pressure within the connecting pipe 26 cause the second piston 27, located away from the connecting block 25, to slide. The first adjusting vent plate 28, fixedly connected to the second piston 27, then slides inside the barrier body 3. The first adjusting vent plate 28 is attached to the side of the second adjusting vent plate 29 away from the wind-blowing push plate 11. Both plates have ventilation holes. The sliding of the first adjusting vent plate 28 changes the overlap area between it and the ventilation holes on the second adjusting vent plate 29. When the wind is strong, the overlap area decreases, reducing the wind throughput and further weakening the wind. When the wind is weak, the overlap area increases, ensuring sufficient air circulation and meeting the air exchange requirements for seedling photosynthesis and the growth environment.

[0061] When the wind weakens, the reverse force of spring 15 in the initial ventilation unit 1 pushes rack 14 to reset, and rack 14 drives gear 17 to rotate in the opposite direction, so that the wind guide plate 18 returns to its initial angle. At the same time, the spring force of spring 24 in the subsequent ventilation unit 2 pushes the first piston 23 to reset, the air pressure in the connecting pipe 26 returns to normal, and the second piston 27 drives the first adjusting air outlet plate 28 to reset, so that the overlapping area of ​​the ventilation holes returns to a suitable state. This realizes that the device automatically adjusts according to the wind force changes, and continuously provides stable and effective wind protection for the plateau afforestation area.

[0062] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
