Description

Technical Field

[0001] The invention relates to the technical field of civil engineering, and in particular to a rotary multi-aperture windshield with an automatic positioning function. Background Art

[0002] With the acceleration of urbanization and the continuous increase in building heights, high-rise buildings, bridges, wind power generation facilities and other structures have put forward higher requirements for their ability to resist wind loads. Wind loads not only affect the safety and stability of the structure, but may also cause serious economic losses and safety hazards. At present, this problem is generally solved by setting up wind shields. The structure of traditional wind shields is relatively simple and it is difficult to flexibly cope with complex wind environments under different wind speeds, wind directions and terrain conditions. This results in poor results in extreme weather or specific working conditions, and may even be damaged due to excessive wind pressure.

[0003] The patent with the announcement number "CN205840516U" discloses "a kind of guardrail for construction", including a door frame, which is composed of a number of longitudinal columns and a number of transverse beams. A door panel is installed on one side of the door frame, and an oblique support is hinged on the other side of the door panel. The lower end of the oblique support is bent, and a through hole is opened in the bent part, and a steel chisel is provided in the through hole; a bolt hole is reserved on the lowermost transverse beam of the transverse beam, and a number of air holes are opened on the door panel, and a wind shield is hinged on the upper end of the air hole, wherein a part of the wind shield is located on one side of the door panel, and the other part is located on the other side of the door panel, and magnets are embedded around the air hole. The device can only realize the opening and closing of the air hole, and cannot adjust the size of the air hole in the open state.

[0004] The patent with the announcement number "CN219550748U" discloses "a green building design energy-saving ventilation structure", including a building wall for installation, a mounting plate installed in the building wall by fixing bolts, and a ventilation duct arranged in the middle of one side of the mounting plate, and also includes an adjustment mechanism, a windshield and a hinge. The windshield is installed inside the mounting plate through the adjustment mechanism; the adjustment mechanism includes a bottom plate, a driven gear and an arc-shaped rack.

For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings.

[0023] Embodiment 1 like Figure 1 — Figure 3 As shown, a rotating multi-aperture windshield with automatic positioning function includes a baffle 1, one side of the baffle 1 is a windward side, the other side of the baffle 1 is a leeward side, a plurality of air inlet holes 3 are provided on the baffle 1, a rotatable adjustment plate is installed on the leeward side of the baffle 1, and the adjustment plate is provided with adjustment holes of different sizes corresponding to the air inlet holes 3 one by one; An amplitude sensor (not shown in the figure) for monitoring the vibration of the baffle is installed on the baffle, and the amplitude sensor is connected to a controller for controlling the rotation of the regulating plate.

[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 3 and Figure 5 — Figure 7 As shown, the adjusting piece is a circular adjusting piece 101, and the circular adjusting piece 101 is divided into a first adjusting piece 1011, a second adjusting piece 1012 and a third adjusting piece 1013; the adjusting holes are divided into a first opening 1021, a second opening 1022, a third opening 1023 and a fourth opening 1024 from large to small, and the diameter of the first opening 1021 is consistent with the diameter of the air inlet hole 3 or larger than the diameter of the air inlet hole 3, that is: when the circular adjusting piece 101 is rotated to the point where the first opening 1021 is concentric 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 remaining openings are rotated to the point where they are concentric with the air inlet hole 3, it is equivalent to reducing the opening of the baffle 1 and also reducing the air intake.

[0029] like Figure 4 As shown, the present embodiment is further provided with a fixed support plate 5 located on the leeward side of the baffle 1, a space for installing a circular adjustment piece 101 is formed between the fixed support plate 5 and the baffle 1, a first rotating shaft hole 4 is provided at the center of the circular adjustment piece 101, a first rotating shaft 7 is installed in the first rotating shaft hole 4, and a driving motor 8 for driving the first rotating shaft 7 to rotate is provided on the fixed support plate 5. When in use, the first rotating shaft 7 is driven to rotate by the driving motor 8, and the first rotating shaft 7 is connected to the first rotating shaft hole 4 of the circular adjustment piece 101 by a key, which can drive the circular adjustment piece 101 to rotate, thereby adjusting the size of the air inlet hole 3 of the baffle.

[0030] During the adjustment process, since each circular adjustment piece 101 and the drive motor 8 are independently controlled, precise adjustment can be performed. For example, different air inlets can be set under the same wind conditions. At the 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 the 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.

[0031] In this embodiment, four air inlet holes form a group, and the center of each group of air inlet holes is provided with a second shaft hole 2 for accommodating the first shaft 7. The adjustment holes on the circular adjustment sheet 101 form a group of four, and each group of adjustment holes corresponds to the positions of the adjustment holes and air inlet holes in each group of air inlet holes. Figure 5— Figure 7 As shown, the first adjusting piece 1011 has a first opening 1021 and a fourth opening 1024, the second adjusting piece 1012 has a first opening 1021, a third opening 1023 and a fourth opening 1024, and the third adjusting piece 1013 has a first opening 1021, a second opening 1022 and a third opening 1023. The first adjusting piece 1011 actually has four baffles (i.e., the space between the first opening 1021 and the next group of fourth openings 1024, the position of the third opening on the second adjusting piece 1012 or the third adjusting piece 1013), and when the third adjusting piece 1013 is rotated to this angle, the air inlet 3 can be completely blocked.

[0032] In other embodiments, the circular adjustment plate 101 can be configured as 1 / 2 / 4 / 5 or more adjustment plates with adjustment holes of different sizes, and each adjustment plate can also be provided with 1 / 2 / 3 / 4 or more adjustment holes of different sizes, and is not limited to the specifications of the adjustment plates and adjustment holes in this embodiment.

[0033] During the adjustment process, the rotation angle of each circular adjustment piece 101 can be determined according to the wind force and the vibration of the baffle 1, thereby achieving the adjustment of the air intake volume.

[0034] In order to better install the fixed support plate 5, a support column 6 is provided on the leeward side of the baffle 1, and the fixed support plate 5 can be connected to the support column 6 by bolts to fix it. In some embodiments, in order to prevent the fixed support plate 5 from being affected by the wind passing through the air inlet 3 (i.e., to avoid Figure 2 In the viewing direction, the fixed support plate 5 blocks the air inlet 3), the fixed support plate 5 can also be set as two cross rods arranged crosswise, and the drive motor 8 is set at the center of the cross rod.

[0035] 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 and sends a signal to the drive motor 8. The drive motor 8 drives the circular adjustment plate 101 to rotate, so that the adjustment hole on the circular adjustment plate 101 blocks the air inlet 3 to a certain extent (when the first opening 1021 corresponds to it, it is in a completely unblocked state), thereby adjusting the air intake volume.

[0036] Embodiment 2 like Figure 8 and Fig. 9 As shown, in this embodiment, the adjustment sheet is a baffle adjustment portion 103, and the baffle adjustment portion 103 is composed of a plurality of baffles that can rotate around the center of the baffle adjustment portion, and baffle holes of different sizes are opened on the baffles.

[0037] like Fig.10 — Fig.12As shown, the present embodiment further includes a fixed support plate 5 located on the leeward side of the baffle 1, a space for installing the baffle adjusting portion 103 is formed between the fixed support plate 5 and the baffle 1, and a first motor 51, a second motor 52, a third motor 53 and a fourth motor 54 are respectively arranged on the fixed support plate 5, the first motor 51 is connected to the first driving gear 55, the second motor 52 is connected to the second driving gear 56, the third motor 53 is connected to the third driving gear 57, and the fourth motor 54 is connected to the fourth shaft sleeve 64.

[0038] A second rotating shaft 1038 is provided at the center of the baffle adjusting portion 103, and a first sleeve 61, a second sleeve 62, a third sleeve 63 and a fourth sleeve 64 are respectively provided on the second rotating shaft 1038, a first baffle 1031 is provided on one side of the first sleeve 61, a first baffle hole 1035 is provided on the first baffle 1031, a first driven gear meshing with the first driving gear 55 is provided on the other side of the first sleeve 61, a second baffle 1032 is provided on one side of the second sleeve 62, a second baffle hole 1036 is provided on the second baffle 1032, and the second sleeve A second driven gear meshing with the second driving gear 56 is provided on the other side of 62, a third baffle 1033 is provided on one side of the third shaft sleeve 63, and a third baffle hole 1037 is provided on the third baffle 1033, a third driven gear meshing with the third driving gear 57 is provided on the other side of the third shaft sleeve 63, and a fourth baffle 1034 is provided on the fourth shaft sleeve 64. In fact, the fourth baffle 1034 also has a fourth baffle hole (this hole does not exist). When the baffle adjusting part 103 is rotated to make the fourth baffle hole correspond to the air inlet hole 3, the air inlet hole 3 is in a completely blocked state. The first sleeve 61, the second sleeve 62, the third sleeve 63 and the second shaft 1038 are all rotatably connected, and the rotations of the four are independent of each other and do not interfere with each other; the fourth motor 54 is connected to the fourth sleeve 64 through the second shaft 1038, and the fourth sleeve 64 and the second shaft 1038 are connected by a key. The rotation of the fourth motor 54 can drive the second shaft 1038 to rotate, and then drive the fourth sleeve 64 and the fourth baffle 1034 to rotate.

[0039] In the foregoing, the diameter of the first blocking hole 1035 is consistent with that of the air inlet hole 3, and the diameters of the second blocking hole 1036 and the third blocking hole 1037 are gradually reduced.

[0040] When this embodiment is used, Fig. 9 and Fig.11 As shown, the four baffles of the baffle adjustment part 103 have two states: a use state rotated to the right and a non-use state rotated to the left, that is, the baffles can rotate within a circumferential range of 180° at most, and will not interfere with the first driving gear 55, the second driving gear 56, and the third driving gear 57. For example, when the wind force is strong, the first baffle 1031 can be rotated to the use state on the right, and the other three baffles can be rotated to the non-use state on the left. At this time, the air intake of the air inlet 3 is the largest.

[0041] It should be noted that Fig.12 In order to conveniently display the specific structure of the baffle adjustment portion 103, a schematic diagram is shown in which four baffles are fully unfolded (360° unfolded). After the baffle adjustment portion 103 is installed on the baffle 1, each baffle has only two working states (i.e., two working positions) and can be unfolded to 180° at most.

[0042] In this embodiment, in order to prevent the fixed support plate 5 from being affected by the wind passing through the air inlet hole 3 (i.e., to avoid Figure 8 In the viewing direction, the fixed support plate 5 blocks the air inlet 3), the position of the fixed support plate 5 corresponding to the air inlet 3 can also be hollowed out, or the fixed support plate 5 can be formed by rods, and the first motor 51, the second motor 52, the third motor 53 and the fourth motor 54 can be installed on the rods.

[0043] The other structures of this embodiment are consistent with those of the first embodiment.

[0044] Embodiment 3 like Fig.13 As shown, in this embodiment, the adjustment piece can also be set as a combination of a circular adjustment piece 101 and a baffle adjustment portion 103. The number of circular adjustment pieces 101 and the number of baffle adjustment portions 103 can be freely arranged, and this embodiment does not limit them.

[0045] The other structures of this embodiment are consistent with those of the first embodiment.
