Description

Technical Field

[0001] This utility model relates to the field of windbreak wall technology, and more specifically, to a windproof windbreak wall. Background Technology

[0002] Windbreaks, technically known as windbreaks and dust suppression walls or windproof nets, are engineering structures that alter airflow patterns by artificially creating obstacles to reduce wind speed, suppress dust, and protect specific areas. They don't completely block the wind, but rather dissipate its kinetic energy through obstruction, guidance, and turbulence, breaking large, high-speed flows into multiple, low-speed turbulent streams, thus creating a protected wind shadow behind the wall. However, existing windbreaks still have some drawbacks that affect their daily use.

[0003] The primary problem is that existing windbreaks lack devices to reduce stress on the wall surface. Strong winds generate enormous static and dynamic wind pressure on the wall surface. Without pressure relief devices to release some of the pressure, the horizontal thrust acting on the wall foundation and ground will increase dramatically, greatly increasing the risk of the entire wall being pushed down or pushed. For panel windbreaks, the enormous wind pressure may directly cause the wall panels to buckle, deform, or tear. In extreme weather, overloaded walls may partially collapse or collapse entirely, causing direct damage to nearby personnel, equipment, or buildings.

[0004] More importantly, the existing windbreak walls and wind-resistant columns are inconvenient to connect. When connecting the windbreak walls and wind-resistant columns, the windbreak walls need to be supported or the walls need to be lifted for a long time to connect the walls and wind-resistant columns. For the support method, this method increases the number of parts used and the time invested in the installation of support devices. For the lifting installation method, this method consumes the labor intensity of workers. Workers perform cumbersome connection operations at high altitudes, and their exposure to dangerous environments increases, raising the probability of accidents such as falls from heights.

[0005] Crucially, existing windbreaks have low aerodynamic performance. Traditional windbreaks rigidly resist wind pressure in a static manner, bearing a large net wind pressure load. This places extremely high demands on the supporting structure and foundation, posing potential safety risks. Moreover, the material cost remains high. The top of a traditional windbreak will form a concentrated, downstream sweeping strong vortex. After the airflow passes over the top of the wall, it is very easy for the flow to separate, forming a concentrated large-scale vortex behind the wall. This causes the local wind speed to intensify, resulting in severe wind erosion and scouring in the area adjacent to the wall, and shortening the effective protection distance. Utility Model Content

[0006] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a windproof wall to solve the technical problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a windproof wall, comprising a wind-resistant column and a base, wherein the wind-resistant column is fixedly connected above the base, and the wind-resistant column is fixedly provided with a wind-blocking component and a gas unloading device, and the wind-blocking component is fixedly provided with a turbulence device, the wind-blocking component comprising a wind-blocking wall, a strip, a slot, a connecting seat, and bolts, the strip being fixedly connected to the wind-blocking wall and slidably connected to the slot, the wind-resistant column having a slot, the connecting seat being fixedly connected to the wind-resistant column and in close contact with the wind-blocking wall, and the bolts being threadedly connected to the connecting seat and the wind-blocking wall respectively, the gas unloading device comprising a fixed seat, a connecting shaft, a first bearing, a rotating cylinder, a through hole, and a limiting component, the fixed seat being fixedly connected to the wind-resistant column and the connecting shaft respectively, the inner ring of the first bearing being fixedly connected to the connecting shaft, the outer ring of the first bearing being fixedly connected to the rotating cylinder, the rotating cylinder having multiple through holes, and the limiting component being in close contact with the first bearing.

[0008] The present invention is further configured such that the turbulence device includes a second bearing, a rotating column, a connecting column, a wind-receiving head, and a protective shell. The outer ring of the second bearing is fixedly connected to the top of the windbreak wall, the inner ring of the second bearing is fixedly connected to the rotating column, the connecting column is fixedly connected to the wind-receiving head and the rotating column respectively, and the protective shell is fixedly connected to the top of the windbreak wall and has a gap with the rotating column. Multiple second bearings, rotating columns, connecting columns, and wind-receiving heads are provided and evenly arranged on the top of the windbreak wall.

[0009] The present invention is further configured such that the limiting component includes a fixing block, a thread and a threaded sleeve. The fixing block is fixedly connected to the connecting shaft and in close contact with the inner side of the first bearing. The thread is provided at both ends of the connecting shaft. The threaded sleeve is screwed to the connecting shaft and in close contact with the outer side of the first bearing, thereby ensuring the stability of the first bearing.

[0010] The present invention is further configured such that the windbreak wall may be provided with multiple ventilation holes, and the ventilation holes are inclined to improve the wind blocking effect.

[0011] The present invention is further configured such that the length of the threaded sleeve is greater than the length of the thread, thereby slowing down the aging of the thread.

[0012] The present invention is further configured such that the protective shell has multiple mating holes, and there is a gap between the mating holes and the rotating column, which ensures the normal operation of the rotating column.

[0013] The present invention is further configured such that a plurality of guide vanes are fixedly provided at the bottom of the windbreak wall, and the guide vanes are arranged in a staggered manner at various installation angles to improve the wind blocking effect.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a windproof wall with the following advantages: 1. A complete, easy-to-install windbreak assembly is formed by the tight fit between the windbreak wall, inserts, slots, connectors, and bolts. Inserting the inserts into the slots allows for quick positioning of the windbreak wall and the wind-resistant column. The bolts and connectors then enable a quick connection between the windbreak wall and the wind-resistant column. The connection operation is simple, requiring no complicated procedures or special tools, allowing workers to complete the installation quickly, reducing the time spent on each step and accelerating the overall construction progress. During maintenance, disassembly and reassembly are convenient, and repairs or component replacements can be completed without damaging the original structure, shortening maintenance time and minimizing the impact on the normal use of the windbreak wall.

[0015] 2. A complete gas load reduction device is formed by the tight fit between the fixed seat, connecting shaft, first bearing, rotating cylinder, through hole, fixing block, thread and threaded sleeve. By rotating the cylinder around the first bearing, part of the wind force in front of the windbreak wall is converted into rotational force, reducing the impact pressure on the wall surface and avoiding deformation and cracking of the wall caused by localized stress concentration; it balances the wind pressure difference in different areas of the wall surface, prevents fatigue wear of connecting parts caused by uneven stress, and extends the overall service life of the windbreak wall; because the stress on the wall surface is effectively controlled, the probability of structural damage is greatly reduced, which can reduce the frequency of daily inspection and maintenance and the amount of maintenance work, saving labor and material costs.

[0016] 3. Through the close cooperation between the second bearing, rotating column, connecting column, wind receiver, and protective shell, a complete airflow disturbance device is formed. By rotating the connecting column and the wind receiver, the airflow trajectory at the top of the wall is disrupted, avoiding the formation of strong vortices or through drafts, allowing the wind to flow more smoothly above the wall, significantly reducing the wind speed in the area behind the wall, and improving the windproof coverage effect. By disturbing the airflow, the wind pressure on the wall surface can be dispersed, avoiding the concentration of pressure in the upper and middle parts of the wall, reducing the risk of wall deformation and cracking, and extending the service life of the structure.

[0022] Please see Figures 1-5 A windbreak wall includes a wind-resistant column 1 and a base 2. The wind-resistant column 1 is fixedly connected to the base 2. The wind-resistant column 1 is fixedly equipped with a wind-blocking component and a gas unloading device. The wind-blocking component is fixedly equipped with a turbulence device. The wind-blocking component includes a wind-blocking wall 3, a strip 4, a slot 5, a connecting seat 6, and bolts 7. The strip 4 is fixedly connected to the wind-blocking wall 3 and slidably connected to the slot 5. The wind-resistant column 1 has a slot 5. The connecting seat 6 is fixedly connected to the wind-resistant column 1 and in close contact with the wind-blocking wall 3. The bolts 7 are threadedly connected to the connecting seat 6 and the wind-blocking wall 3 respectively. The gas unloading device includes a fixed seat 8, a connecting shaft 9, a first bearing 10, a rotating cylinder 11, a through hole 12, and a limiting component. The fixed seat 8 is fixedly connected to the wind-resistant column 1 and the connecting shaft 9 respectively. The inner ring of the first bearing 10 is fixedly connected to the connecting shaft 9. The outer ring of the first bearing 10 is fixedly connected to the rotating cylinder 11. The rotating cylinder 11 has multiple through holes 12. The limiting component is in close contact with the first bearing 10.

[0023] In a further embodiment of this application, the turbulence device includes a second bearing 13, a rotating column 14, a connecting column 15, a wind-receiving head 16, and a protective shell 17. The outer ring of the second bearing 13 is fixedly connected to the top of the windbreak wall 3, and the inner ring of the second bearing 13 is fixedly connected to the rotating column 14. The connecting column 15 is fixedly connected to the wind-receiving head 16 and the rotating column 14 respectively. The protective shell 17 is fixedly connected to the top of the windbreak wall 3 and has a gap with the rotating column 14. Multiple second bearings 13, rotating columns 14, connecting columns 15, and wind-receiving heads 16 are provided and are evenly arranged on the top of the windbreak wall 3.

[0024] In a further embodiment of this application, the limiting component includes a fixing block 18, a thread 19, and a threaded sleeve 20. The fixing block 18 is fixedly connected to the connecting shaft 9 and in close contact with the inner side of the first bearing 10. The thread 19 is provided at both ends of the connecting shaft 9. The threaded sleeve 20 is screwed to the connecting shaft 9 and in close contact with the outer side of the first bearing 10. Rotating the threaded sleeve 20 causes the threaded sleeve 20 to contact the end face of the first bearing 10 and cooperate with the fixing block 18 to prevent the first bearing 10 from sliding laterally. At the same time, the rotation of the threaded sleeve 20 ensures the convenience of installing and disassembling the first bearing 10 and the rotating cylinder 11.

[0025] In a further embodiment of this application, the windbreak wall 3 may be provided with a plurality of ventilation holes 21. The ventilation holes 21 are inclined and the inclined ventilation holes 21 can effectively avoid the direct impact of high-speed airflow, making the wind field behind the wall more stable.

[0026] In a further embodiment of this application, the length of the threaded sleeve 20 is greater than the length of the thread 19, protecting the thread 19 from aging caused by wind and sand.

[0027] In a further embodiment of this application, the protective shell 17 is provided with a plurality of mating holes 22. There is a gap between the mating holes 22 and the rotating column 14. The mating holes 22 can ensure the normal rotation of the rotating column 14 and also provide lateral support for the rotating column 14, reducing the impact of wind on the rotating column 14.

[0028] In a further embodiment of this application, a plurality of guide vanes 23 are fixedly provided at the bottom of the windbreak wall 3. The guide vanes 23 are arranged in a staggered manner with a variety of installation angles. The guide vanes 23 with different angles will apply a force in a different direction to each airflow passing through the bottom, thereby reducing the wind speed passing through the bottom gap.

[0029] In this embodiment, when the device is needed, during installation, the dimensions between the wind-resistant columns 1 are determined and the base 2 is fixed to the ground. Then, the windbreak wall 3 is inserted into the slot 5 through the insert 4, and the windbreak wall 3 is fixed to the connecting seat 6 using bolts 7 to complete the installation of the windbreak wall 3. Then, the gas load reduction device is fixed to the wind-resistant column 1 through the fixing seat 8. When the wall is subjected to wind force, the through hole 12 on the rotating cylinder 11 is pushed by the wind force, causing the rotating cylinder 11 to rotate on the connecting shaft 9 through the first bearing 10. The rotating cylinder 11 and the through hole 12 convert part of the wind force blowing towards the wall into the rotation of the rotating cylinder 11, reducing the impact of the wind force on the wall.

[0030] More specifically, when wind passes the top of the windbreak wall 1, flow separation easily occurs, forming a concentrated, large-scale vortex behind the wall. This causes the local wind speed to intensify, resulting in severe wind erosion and scouring of the area adjacent to the wall. The wind-receiving head 16 receives wind force to provide steering force to the connecting column 15 and transmits it to the rotating column 14. The rotating column 14 rotates around the second bearing 13 under the rotational force, causing multiple wind-receiving heads 16 and connecting columns 15 to continuously rotate under the wind, dispersing the concentrated airflow at the top of the wall and further reducing the wind speed behind the wall. The protective shell 17 can enclose the second bearing 13 to prevent sand and soil intrusion, and with the cooperation of the hole 22, it can... The rotation of the rotating column 14 is ensured and lateral support is provided. The rotating sleeve 20 contacts the end face of the first bearing 10 and cooperates with the fixing block 18 to prevent the first bearing 10 from sliding laterally. At the same time, the rotation of the sleeve 20 ensures the ease of installation and disassembly of the first bearing 10 and the rotating cylinder 11. The guide vanes 23 at different angles at the bottom of the windbreak wall 1 will apply force in different directions to each airflow passing through the bottom, thereby reducing the wind speed passing through the bottom gap. The inclined ventilation holes 21 can effectively avoid the direct impact of high-speed airflow, making the wind field behind the wall more stable.

[0031] In summary, during the use or operation of the overall equipment: during installation, determine the dimensions between the wind-resistant columns 1 and fix the base 2 to the ground. Then, insert the windbreak wall 3 into the slot 5 through the insert 4, and then use bolts 7 to fix the windbreak wall 3 to the connecting seat 6 to complete the installation of the windbreak wall 3. Then, fix the gas load reduction device to the wind-resistant column 1 through the fixing seat 8. When the wall is subjected to wind force, the through hole 12 on the rotating cylinder 11 is pushed by the wind force, causing the rotating cylinder 11 to rotate on the connecting shaft 9 through the first bearing 10. The rotating cylinder 11 and the through hole 12 convert part of the wind force blowing towards the wall into the rotation of the rotating cylinder 11, reducing the impact of the wind force on the wall.

[0032] When wind passes the top of the windbreak wall 1, flow separation easily occurs, forming a concentrated, large-scale vortex behind the wall. This causes the local wind speed to actually increase, resulting in severe wind erosion and scouring in the area adjacent to the wall. The wind-receiving head 16 receives wind force to provide steering force to the connecting column 15 and transmits it to the rotating column 14. The rotating column 14 rotates around the second bearing 13 under the rotational force, causing multiple wind-receiving heads 16 and connecting columns 15 to continuously rotate under the wind, dispersing the concentrated airflow at the top of the wall and further reducing the wind speed behind the wall. The protective shell 17 can wrap the second bearing 13 to prevent sand and soil intrusion, and the matching hole 22 can ensure rotation. The normal rotation of the moving column 14 also provides lateral support for the rotating column 14. The rotating screw sleeve 20 makes the screw sleeve 20 contact the end face of the first bearing 10 and cooperate with the fixing block 18 to prevent the first bearing 10 from sliding laterally. At the same time, the rotation of the screw sleeve 20 ensures the convenience of installation and disassembly of the first bearing 10 and the rotating cylinder 11. The guide vanes 23 at different angles at the bottom of the windbreak wall 1 will apply a force in different directions to each airflow passing through the bottom, thereby reducing the wind speed passing through the bottom gap. The inclined ventilation holes 21 can effectively avoid the direct impact of high-speed airflow, making the wind field behind the wall more stable.

[0033] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
