Abstract
Description
Technical Field
[0001] The invention relates to the technical field of civil engineering, and in particular to a sliding-pushing multi-gear windproof plate capable of changing the size of an air inlet. Background Art
[0002] Driven by the strong development of architectural technology, the city's outline continues to extend upward, and giant structures such as high-rise buildings, cross-sea bridges and wind power towers are facing increasingly severe wind challenges. As a natural force that cannot be ignored, wind load not only tests the safety bottom line and stability of these structures, but is also directly related to the economic security of society and the safety of people's lives and property. Traditional windbreak designs are often limited to fixed structures and single material selections, and lack the ability to flexibly respond to different wind conditions. In complex environments with sudden strong winds and changing wind directions, these traditional windbreaks often seem powerless and difficult to effectively reduce the impact of wind loads on structures. What's more, in extreme weather conditions, they may be damaged due to the inability to withstand huge wind pressure, further exacerbating the risk of the structure.

Although the device realizes the adjustment of the size of the ventilation duct, the size of the ventilation duct is large and covers the entire wall, making this adjustment method relatively rough.
[0005] Therefore, a sliding type multi-position wind shield which can change the size of the air inlet is proposed. Summary of the invention

[0022] The present invention is further described below in conjunction with the accompanying drawings.
[0023] Embodiment 1 like Figure 1 and Figure 2 As shown, a sliding type multi-gear wind shield capable of changing the size of an air inlet comprises a baffle 1, one side of the baffle 1 being a windward side, the other side of the baffle 1 being a leeward side, a plurality of air inlet holes 3 being provided on the baffle 1, a movable adjustment device being installed on the leeward side of the baffle 1, and adjustment holes of different sizes corresponding to the air inlet holes 3 being provided on the adjustment device; An amplitude sensor (not shown in the figure) for monitoring the vibration of the baffle 1 is installed, and the amplitude sensor is connected to a controller for controlling the movement of the regulating device.
[0024] In this embodiment, the baffles 1 are installed on both sides of the bridge to block the crosswind on the bridge and reduce its impact on the bridge and the vehicles traveling on it. During use, the main adjustment directions are as follows: 1. When the wind is strong, increase the air inlet. When the wind is strong, the bridge structure will be subject to greater wind loads. At this time, if the air inlet of the windshield is kept small, it may restrict the passage of wind flow, resulting in increased wind pressure and adverse effects on the bridge structure. Therefore, appropriately increasing the air inlet can reduce wind pressure: by increasing the amount of wind flow passing through, reducing the wind pressure difference before and after the windshield, thereby reducing the pressure on the bridge structure; at the same time, improve stability: make the wind flow pass through the bridge more smoothly, and reduce vibration and instability caused by uneven wind pressure.
[0025] 2. When the wind is low, adjust the air inlet to a smaller size. This has the following multiple meanings: 1. Reduce vortex vibration: By limiting the amount of wind flow, the formation and development of vortices can be reduced, thereby reducing the risk of vortex vibration (vortex vibration: when smaller wind forces pass through larger air inlets, vortices may form behind the wind shield, causing vortex vibration on the bridge, affecting the comfort and safety of the structure).
[0026] 2. Improve durability: Reduce fatigue damage caused by vibration phenomena such as vortex vibration and extend the service life of the bridge structure (vibration phenomena such as vortex vibration may accelerate fatigue damage of the bridge structure, resulting in more frequent maintenance and inspection).
[0027] 3. Energy saving and consumption reduction: When the wind is weak, limiting the amount of wind flow by reducing the air inlet can help reduce the energy consumption of the bridge structure and the energy loss caused by vibration.
[0028] like Figure 2 and Figure 3 As shown, multiple sets of guide parts 2 are installed on the leeward side of the baffle 1. In this embodiment, the guide parts 2 are arranged horizontally. The guide parts 2 can be arranged to be continuous (such as Figure 2 as shown) or discontinuous (as shown Figure 5 As shown in the figure, each group of guide parts 2 is a guide part 2 located on the same horizontal line, and each group of guide parts 2 includes a first guide rod 21 and a second guide rod 22 arranged opposite to each other. A space for the adjustment device to move is formed between the first guide rod 21 and the second guide rod 22, and the space can also play a certain guiding role to prevent the adjustment device from being deflected when moving.
[0029] The adjusting device is a multi-hole adjusting baffle 4 corresponding to the multiple groups of guide parts 2 one by one, and each multi-hole adjusting baffle 4 is provided with adjusting holes of the same or different sizes.
[0030] The adjustment hole includes a first opening 41 and a second opening 42. The size of the first opening 41 is larger than the size of the air inlet hole. The first opening 41 is rectangular, and the length of its short side is larger than the diameter of the air inlet hole 3. The size of the second opening 42 is not larger than the size of the air inlet hole 3. When the porous adjustment baffle 4 moves to the point where the first opening 41 coincides with the air inlet hole 3, the opening of the baffle 1 is the largest, and the air intake is also the largest; when the second opening 42 is rotated to the point where it is concentric with the air inlet hole 3, it is equivalent to reducing the opening of the baffle 1 and also reducing the air intake.
[0031] A space that can block the air inlet hole 3 (i.e., the third opening, but the actual diameter of the hole is 0) is formed between the first opening 41 and the second opening 42 on each porous adjustment baffle 4. When the porous adjustment baffle 4 moves to the point where the third opening overlaps with the air inlet hole 3, the air inlet hole 3 can be blocked.
[0032] A traction rod 43 is provided at the end of the porous adjustment baffle 4 to drive it to move, a first support plate 51 for placing the first motor 5 is provided on the leeward side of the baffle 1, a gear is connected to the output shaft of the first motor 5, and a rack meshing with the gear is provided on the traction rod 43, and the traction rod 43 and the porous adjustment baffle 4 can be driven to move by the rotation of the first motor 5. The traction rod 43 and the first motor 5 can be provided at only one end of the porous adjustment baffle 4, or at both ends of the porous adjustment baffle 4. When provided at both ends, it is necessary to ensure that the first motors 5 at the two locations rotate synchronously.
[0033] In this embodiment, different porous adjustment baffles 4 can have second openings 42 of different sizes, thereby making targeted adjustments to the size of the air inlet 3. For example, different air inlets can be set under the same wind conditions. At a lower position of the baffle 1, the size of the air inlet can be increased (i.e., the adjustment hole with a larger diameter is rotated to be concentric with the air inlet 3), and at a higher position of the baffle 1, the size of the air inlet can be reduced (i.e., the adjustment hole with a smaller diameter is rotated to be concentric with the air inlet 3). The purpose of this setting is to reduce vortices and turbulence: when the height of the wind shield is low, if the air inlet is too large, the wind flow is prone to form vortices and turbulence when passing through, increasing the impact and vibration on the bridge structure. As the height of the wind shield increases, gradually reducing the air inlet can effectively guide the wind flow to pass more smoothly and reduce the generation of vortices and turbulence.
[0034] In some embodiments, second openings 42 of different sizes may be provided on the same porous adjustment baffle 4; or the guide portion 2 may be provided vertically, and the guide portions 2 located in the same vertical column are a group, and correspondingly, the moving direction of the porous adjustment baffle 4 may also be set vertically.
[0035] During the adjustment process, the porous adjustment baffles 4 in each group of guide parts 2 can be individually controlled to move according to the wind force and the vibration of the baffle 1, thereby achieving the adjustment of the air intake volume.
[0036] When this embodiment is in use, the baffles 1 can be installed continuously or discontinuously on both sides of the bridge. When there is a crosswind, the amplitude sensor detects the vibration of the baffle 1 in real time, sends a signal to the first motor 5, and drives the multi-porous adjustment baffle 4 to move through the first motor 5, so that the adjustment holes arranged on it block the air inlet 3 to a certain extent (when the first opening 41 corresponds to it, it is in a completely unblocked state), thereby adjusting the air intake volume.
[0037] Embodiment 2 like Figure 5 — Figure 8As shown, in this embodiment, the adjustment device is a single-hole adjustment baffle 6 corresponding to the guide portion 2, and multiple single-hole adjustment baffles 6 are arranged in each group of guide portions 2. The single-hole adjustment baffle 6 includes an adjustment portion 61, and a third opening 62 of the same or different size is arranged on the adjustment portion 61.
[0038] The size of some third openings 62 is the same as that of the air inlet hole 3. When the adjustment part 61 moves to the position where the third opening 62 corresponds to the air inlet hole 3, the air intake volume is maximum. The size of some third openings 62 is smaller than that of the air inlet hole 3. When corresponding to the air inlet hole 3, the air intake volume is small (the actual air intake volume is related to the actual size of the hole). There are also some third openings 62 that do not actually exist (the diameter is 0). When corresponding to the air inlet hole 3, the air intake volume is 0.
[0039] A second support plate 71 for placing the second motor 7 is provided on the leeward side of the baffle 1, the output shaft of the second motor 7 is connected to one end of the first connecting rod 63, the other end of the first connecting rod 63 is connected to one end of the second connecting rod 64 through a pin, and the other end of the second connecting rod 64 is connected to the side wall of the adjusting portion 61 through a pin. When the second motor 7 rotates, the first connecting rod 63 rotates accordingly, thereby driving the second connecting rod 64 to rotate, and pulling the adjusting portion 61 to move.
[0040] In this embodiment, the guide portions 2 are also arranged in a horizontal direction, and the guide portions 2 located on the same horizontal line are grouped together. In other embodiments, the guide portions 2 may also be arranged in a vertical direction.
[0041] The other structures of this embodiment are consistent with those of the first embodiment.
[0042] Embodiment 3 In some embodiments, the regulating device may also be configured as a combination of a multi-hole regulating baffle 4 and a single-hole regulating baffle 6, that is, a combination of Embodiment 1 and Embodiment 2. The specific structure has been described in detail in Embodiment 1 and Embodiment 2, and will not be described in detail in this embodiment.
