Description

Technical Field

[0001] The invention relates to the technical field of bridge wind protection, and in particular to an adaptive wind barrier. Background Art

[0002] In recent years, with the rapid development of my country's transportation industry, railway and highway lines have extended to mountainous areas and coastal areas, there are more and more bridges with larger spans, and the wind environment has become more severe. Under the influence of strong winds, driving safety on bridges faces huge challenges. At present, setting up wind barriers is the most economical and effective wind protection measure, which has been widely used in engineering projects.

[0003] Permeability is a key factor affecting the wind-blocking effect of wind barriers. As the permeability decreases, the wind-blocking effect improves, but the aerodynamic resistance of the wind barrier to the bridge will increase, and the force on itself will also increase. According to current specifications, when the ambient wind speed is greater than 25m / s, the highway bridge will be closed. When the ambient wind speed is greater than 30m / s, railway EMU trains are strictly prohibited from entering the wind zone. When the wind speed exceeds the suspension requirement, vehicles are prohibited from passing. If the load on the wind barrier continues to increase at this time, it may cause the wind barrier to break or be damaged, and even affect the wind-resistant safety of the bridge structure. Therefore, if the permeability can be increased under extreme wind speeds, damage under strong winds can be reduced, and the load on the bridge can be reduced, the safety of the bridge structure will be effectively improved.

[0004] At present, the wind barriers that can change the air permeability are mainly intelligent wind barriers, which achieve the adjustment of air permeability by introducing automated monitoring and control structures in the wind barriers. However, this design will make the overall structure of the wind barrier complex and costly, and it is prone to failure in severe weather such as strong winds and heavy rains. For example, patent CN115928616A discloses that a power device is used to drive multiple guide blades to rotate synchronously to achieve the adjustment of the wind attack angles of multiple guide blades so as to achieve adaptive adjustment of the wind-blocking and diversion functions in accordance with changes in the external environment. This patent has the aforementioned problems. Therefore, it is very urgent to study an adaptive wind barrier that can achieve automatic change of air permeability, has a simple structure, stable performance, and can adapt to severe weather. Summary of the invention

[0005] In view of this, the present invention aims to propose an adaptive wind barrier to solve the problem that the intelligent wind barrier in the prior art has a complex structure and is prone to malfunction in severe weather.

[0006] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0007] An adaptive wind barrier is arranged on both sides of a bridge along the driving direction, characterized in that it comprises support columns, the support columns comprise a first support column and a second support column, and a plurality of fixed barrier strips and movable barrier strips are arranged between the first support column and the second support column;

Moreover, it has stable and reliable performance in severe weather and is not prone to malfunction. It can block wind normally when the wind speed does not reach the limit. When the wind speed exceeds the limit, the movable barrier strips automatically open to increase the air permeability.

[0058] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0059] Example 1

[0060] like Figure 1-5 As shown, an adaptive wind barrier is arranged on both sides of a bridge along the driving direction, comprising a support column 1, wherein the support column 1 comprises a first support column 11 and a second support column 12, and a plurality of fixed barrier strips 2 and movable barrier strips 3 are arranged between the first support column 11 and the second support column 12;

[0061] The fixed barrier strip 2 is located on the windward side, and the movable barrier strip 3 is located on the driving side. The fixed barrier strip 2 and the movable barrier strip 3 are sequentially arranged from top to bottom along the supporting column 1;

[0062] The fixed barrier strips 2 and the movable barrier strips 3 are both provided with a plurality of ventilation holes 100, and the ventilation holes 100 are used to guide the cross wind acting on the adaptive wind barrier;

[0063] The support column 1 is provided with a sliding control device 4, and the movable barrier strip 3 is movably connected to the support column 1 through the sliding control device 4. The sliding control device 4 can automatically adjust the distance between the movable barrier strip 3 and the support column 1 according to the wind speed, thereby changing the air permeability of the adaptive wind barrier.

[0064] Specifically, when the fixed barrier strips 2 are located on the windward side and the movable barrier strips 3 are located on the driving side, air inlets are formed between adjacent fixed barrier strips 2, and air outlets are formed between adjacent movable barrier strips 3. When the limited wind speed is not reached, the crosswind flows in from the air inlet and the air holes 100 on the fixed barrier strips 2, and then flows out from the air outlet and the air holes 100 on the movable barrier strips 3. When the limited wind speed is exceeded, the movable barrier strips 3 are moved toward the driving side through the sliding control device 4, so that the distance between the movable barrier strips 3 and the supporting column 1 is increased, and air outlets are formed obliquely above and below the fixed barrier strips 2, so as to improve the air permeability and reduce the wind load. When the airflow passes through the air outlet, the movable barrier strips 3 can disperse and guide the airflow in the upward and downward directions respectively, and can make the airflow guided by the upper and lower adjacent movable barrier strips 3 offset each other.

[0065] The adaptive wind barrier described in the present application is composed entirely of mechanical parts and has a simple overall structure, which is easy to produce, assemble and maintain. In addition, it has stable and reliable performance in severe weather and is not prone to malfunction. It can block wind normally when the wind speed does not reach the limit. When the wind speed exceeds the limit, the movable barrier strips 3 automatically open to increase the air permeability. After the strong wind, the movable barrier strips 3 can automatically move to their original positions, so that the wind barrier can adapt to different weather.

[0066] Preferably, the fixed barrier strips 2 and the movable barrier strips 3 are arranged in parallel.

[0067] Preferably, the support column 1 is configured as an “I”-shaped structure.

[0068] Preferably, a first anchor plate 110 is provided at the lower end of the first supporting column 11, and the first anchor plate 110 is fixed together with the bridge. A second anchor plate 120 is provided at the lower end of the second supporting column 12, and the second anchor plate 120 is fixed together with the bridge. This arrangement can improve the overall fixing firmness of the wind barrier.

[0069] As a preferred example of the present application, the first support column 11 includes a first vertical plate 111, a second vertical plate 112 and a third vertical plate 113, the first vertical plate 111 and the third vertical plate 113 are connected together through the second vertical plate 112, the first vertical plate 111 and the third vertical plate 113 are arranged in parallel, and the first vertical plate 111 and the second vertical plate 112 are arranged vertically;

[0070] The second supporting column 12 includes a fourth vertical plate 124, a fifth vertical plate 125 and a sixth vertical plate 126, the fourth vertical plate 124 and the sixth vertical plate 126 are connected together through the fifth vertical plate 125, the fourth vertical plate 124 and the sixth vertical plate 126 are arranged in parallel, and the fourth vertical plate 124 and the fifth vertical plate 125 are arranged vertically.

[0071] Specifically, this design has a simple structure and can effectively improve the wind resistance of the support column 1.

[0072] Preferably, the first support column 11 is integrally formed, or is supported by welding of the first vertical plate 111 , the second vertical plate 112 and the third vertical plate 113 , and the second support column 12 is manufactured in the same manner as the first support column 11 .

[0073] As a preferred example of the present application, the sliding control device 4 includes a first sliding control device 41 and a second sliding control device 42. One end of the movable barrier strip 3 is movably connected to the first supporting column 11 through the first sliding control device 41, and the other end is movably connected to the second supporting column 12 through the second sliding control device 42; the first sliding control device 41 includes a first friction cylinder 411, a first friction slider 412, a first spring 413 and a first connecting bolt 414; the second sliding control device 42 includes a second friction cylinder 421, a second friction slider 422, a second spring 423 and a second connecting bolt 424.

[0074] Specifically, this design can automatically adjust the air permeability of the movable barrier strips 3 according to changes in wind speed, thereby improving the adaptive ability of the wind barrier under different meteorological conditions.

[0075] As a preferred example of the present application, one end of the first friction cylinder 411 is connected to the first vertical plate 111, and the other end is connected to the third vertical plate 113. The first friction slider 412 is located in the first friction cylinder 411 and can slide in the first friction cylinder 411. The end of the first friction slider 412 close to the windward surface is connected to the first vertical plate 111 through the first spring 413. The first connecting bolt 414 is connected to the end of the first friction slider 412 close to the driving surface after passing through the movable barrier strip 3 and the third vertical plate 113 in sequence, and the first connecting bolt 414 is fixed to the movable barrier strip 3.

[0076] One end of the second friction cylinder 421 is connected to the fourth vertical plate 124, and the other end is connected to the sixth vertical plate 126. The second friction slider 422 is located in the second friction cylinder 421 and can slide in the second friction cylinder 421. The end of the second friction slider 422 close to the windward surface is connected to the fourth vertical plate 124 through the second spring 423. The second connecting bolt 424 is connected to the end of the second friction slider 422 close to the driving surface after passing through the movable barrier strip 3 and the sixth vertical plate 126 in sequence, and the second connecting bolt 424 is fixed together with the movable barrier strip 3.

[0077] Specifically, when the wind speed is low, the elastic force provided by the spring is greater than the friction force, and a smaller gap is maintained between the movable barrier strip 3 and the supporting column 1. At this time, the air permeability is low; when the wind speed is high, the movable barrier strip is pushed toward the driving side, and a larger gap is maintained between the movable barrier strip 3 and the supporting column 1. At this time, the air permeability is high. This setting enables the movable barrier strip 3 to automatically adjust its position under different wind speeds, thereby changing the air permeability of the wind barrier, effectively responding to different wind speeds, and enhancing dynamic adjustment capabilities.

[0078] Preferably, the third vertical plate 113 is provided with an avoidance hole for avoiding the first connecting bolt 414 , and the sixth vertical plate 126 is provided with an avoidance hole for avoiding the second connecting bolt 424 .

[0079] As a preferred example of the present application, the pulling force of the first spring 413 is greater than the friction resistance between the first friction slider 412 and the first friction cylinder 411 ; the pulling force of the second spring 423 is greater than the friction resistance between the second friction slider 422 and the second friction cylinder 421 .

[0080] Specifically, when the wind speed exceeds the restricted wind speed, the wind force is greater than the sum of the spring tension and the friction resistance, and the friction slider starts to slide in the friction cylinder, pushing the movable barrier strip 3 to move toward the driving side. When the first friction slider 412 abuts against the third vertical plate 113, and the second friction slider 422 abuts against the sixth vertical plate 126, the air permeability of the adaptive wind barrier is the largest.

[0081] When the wind speed is lower than the limit wind speed, the spring tension is higher than the sum of the friction resistance and the wind force, and the friction slider begins to slide in the friction cylinder, pushing the movable barrier strip 3 to move toward the windward side. When the first friction slider 412 abuts against the first vertical plate 111 and the second friction slider 422 abuts against the fourth vertical plate 124, the air permeability of the adaptive wind barrier is minimized.

[0082] This setting enables the wind barrier to automatically adjust its air permeability according to changes in wind speed, reducing the impact on the bridge.

[0083] Preferably, the first friction cylinder 411 and the second friction cylinder 421 are respectively arranged perpendicular to the movable barrier strip 3 .

[0084] As a preferred example of the present application, the first friction slider 412 and the second friction slider 422 are made of stainless steel, the first friction cylinder 411 and the second friction cylinder 421 are made of alloy steel, and the inner surfaces are provided with a ceramic coating, and the friction coefficients between the first friction slider 412 and the first friction cylinder 411, and between the second friction slider 422 and the second friction cylinder 421 are both 0.1-0.5.

[0085] Specifically, the stainless steel material has good corrosion resistance and strength, and the ceramic coating has a low friction coefficient. The combination of the two effectively reduces friction and the wear caused by friction. The friction slider can slide smoothly in the friction cylinder, avoiding stagnation or jamming caused by excessive friction, which helps to improve the adjustment accuracy of the movable barrier strip 3 and enables the wind barrier to adjust the air permeability more accurately.

[0086] Preferably, the first friction cylinder 411 and the second friction cylinder 421 are made of Q355 or 40Cr.

[0087] Example 2

[0088] like Figure 6-10 As shown, the difference from Example 1 is that the fixed barrier strips 2 and the movable barrier strips 3 are both located on the driving surface, and the fixed barrier strips 2 and the movable barrier strips 3 are sequentially arranged at intervals from top to bottom along the supporting column 1.

[0089] The fixed barrier strips 2 and the movable barrier strips 3 are both located on the driving surface. When the wind speed limit is not reached, the crosswind on the windward side flows to the driving surface through the ventilation holes 100 on the fixed barrier strips 2 and the movable barrier strips 3. When the wind speed limit is exceeded, the movable barrier strips 3 move toward the driving side through the sliding control device 4, so that the distance between the movable barrier strips 3 and the supporting pillars 1 increases, and air outlets are formed above and below the fixed barrier strips 2, thereby improving the air permeability and reducing the wind load. When the airflow passes through the air outlet, the movable barrier strips 3 can disperse and guide the airflow in the upward and downward directions respectively, and can make the airflow guided by the upper and lower adjacent movable barrier strips 3 offset each other.

[0090] The fixed barrier strip 2 and the movable barrier strip 3 are both installed on the driving surface, which is convenient for installation and maintenance of the fixed barrier strip 2 and the movable barrier strip 3.

[0091] Example 3

[0092] like Figure 11-16 As shown, the difference from Example 1 is that a fixed wind baffle plate 5 is provided between the first supporting column 11 and the second supporting column 12 , the fixed wind baffle plate 5 is located at the lower end of the supporting column 1 , and the fixed wind baffle plate 5 is provided with a plurality of air holes 100 .

[0093] Specifically, the fixed wind baffle plate 5 can enhance the stability of the entire structure, help resist the effects of external wind force, and prevent the structure of the wind barrier from tilting or deforming. Ventilation holes 100 are provided on the fixed wind baffle plate 5 to increase the air permeability of the fixed wind baffle plate 5 and reduce the wind load on the fixed wind baffle plate 5.

[0094] As a preferred example of the present application, one end of the first friction cylinder 411 is connected to the third vertical plate 113, and the other end is not in contact with the first vertical plate 111; the first friction slider 412 is located in the first friction cylinder 411 and can slide in the first friction cylinder 411; the first connecting bolt 414 is connected to the end of the first friction slider 412 close to the driving surface after passing through the movable barrier strip 3 and the third vertical plate 113 in sequence, and the first connecting bolt 414 is fixed together with the movable barrier strip 3; the first vertical plate 111 is provided with a first fixing column 61, and one end of the movable barrier strip 3 is provided with a second fixing column 62; one end of the first spring 413 is connected to the first fixing column 61, and the other end is connected to the second fixing column 62; the first friction cylinder 411 is located between the first spring 413 and the second vertical plate 112;

[0095] One end of the second friction cylinder 421 is connected to the sixth vertical plate 126, and the other end is not in contact with the fourth vertical plate 124. The second friction slider 422 is located in the second friction cylinder 421 and can slide in the second friction cylinder 421. The second connecting bolt 424 is connected to the end of the second friction slider 422 close to the driving surface after passing through the movable barrier strip 3 and the sixth vertical plate 126 in sequence, and the second connecting bolt 424 is fixed together with the movable barrier strip 3; the fourth vertical plate 124 is provided with a third fixing column 63, and the other end of the movable barrier strip 3 is provided with a fourth fixing column 64. One end of the second spring 423 is connected to the third fixing column 63, and the other end is connected to the fourth fixing column 64. The second friction cylinder 421 is located between the second spring 423 and the fifth vertical plate 125.

[0096] Specifically, this arrangement enables the movable barrier strip 3 to automatically adjust its position under different wind speeds, thereby changing the air permeability of the wind barrier, effectively coping with different wind speeds, and enhancing the dynamic adjustment capability.

[0097] Preferably, the third vertical plate 113 is provided with a first avoidance hole and a second avoidance hole, the first avoidance hole is used to avoid the first connecting bolt 414, and the second avoidance hole is used to avoid the second fixing column 62 and the first spring 413, and the sixth vertical plate 126 is provided with a third avoidance hole and a fourth avoidance hole, the third avoidance hole is used to avoid the second connecting bolt 424, and the fourth avoidance hole is used to avoid the fourth fixing column 64 and the second spring 423.

[0098] As a preferred example of the present application, the first friction cylinder 411 and the second friction cylinder 421 are both tilted, and the tilt angle is α, 70°≤α<90°.

[0099] Specifically, the inclined setting can increase the contact area between the friction slider and the friction cylinder, enhance the stability of the movable barrier bar 3 when subjected to external force, and prevent the movable barrier bar 3 from shaking when sliding; when the wind force is less than the limited wind speed, the gravity exerted on the friction slider will enhance the tension of the spring, which is conducive to the rapid recovery of the movable barrier bar 3.

[0100] As a preferred example of the present application, the first friction slider 412 and the second friction slider 422 are made of copper alloy, the first friction cylinder 411 and the second friction cylinder 421 are made of stainless steel, and the inner surfaces are hardened, and the friction coefficients between the first friction slider 412 and the first friction cylinder 411, and between the second friction slider 422 and the second friction cylinder 421 are both 0.1-0.5.

[0101] Specifically, copper alloy has good wear resistance and certain self-lubricating properties, which helps to reduce the wear between the friction slider and the friction cylinder. At the same time, copper alloy has good corrosion resistance and can extend the service life. The combination of copper alloy and stainless steel hardened surface can effectively reduce the friction resistance between the friction slider and the friction cylinder and avoid sticking.

[0102] As a preferred example of the present application, the first friction cylinder 411 and the second friction cylinder 421 both adopt a block structure, and the stress level of the friction slider is increased by applying annular prestress to further increase the friction resistance.

[0103] Specifically, the friction cylinder is divided into two or three blocks, with gaps between the blocks. Steel bars are used to wrap around the outside for pre-tightening. As the gap decreases, the stress will increase and the friction will also increase.

[0104] Example 4

[0105] like Figure 17-21 As shown, the difference from Example 3 is that the fixed barrier strips 2 and the movable barrier strips 3 are both located on the driving surface, and the fixed barrier strips 2 and the movable barrier strips 3 are sequentially arranged at intervals from top to bottom along the supporting column 1.

[0106] The fixed barrier strip 2 and the movable barrier strip 3 are both installed on the driving surface, which is convenient for installation and maintenance of the fixed barrier strip 2 and the movable barrier strip 3.

[0107] The adaptive wind barrier described in the present application has the following advantages: it is composed entirely of mechanical parts and components, and has a simple overall structure, which is easy to produce, assemble and maintain. In addition, it has stable and reliable performance in severe weather and is not prone to malfunction. It can block wind normally when the wind speed does not reach the limit, and when the wind speed exceeds the limit, the movable barrier strips 3 automatically open to increase the air permeability. After the strong wind, the movable barrier strips 3 can automatically move to their original positions. This design enables the wind barrier to automatically adjust the air permeability of the movable barrier strips 3 according to changes in wind speed, thereby improving the adaptive ability of the wind barrier under different meteorological conditions.

[0108] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
