Description

Technical Field

[0001] This invention relates to the field of railway bridge equipment technology, and in particular to a windbreak wall. Background Technology

[0002] The climate along my country's railway lines is complex and changeable. When trains pass through windy areas at high speeds, their aerodynamic performance deteriorates significantly under the influence of strong winds. Trains operating in crosswinds are subject to lateral forces, making them prone to overturning and derailment, seriously threatening passenger safety. To ensure safe train operation in strong wind and sand conditions, windbreaks are typically built on both sides of the tracks on railway bridges, both domestically and internationally, to reduce the impact of crosswinds on train operation. However, traditional windbreaks cannot freely adjust their tilt angle according to actual conditions, lacking flexibility and unsuitable for wind protection measures in various wind and sand environments.

[0003] One related technology provides a louvered wind barrier for high-speed railway bridges. Its wind-blocking blades can change their rotation angle according to the strength of the crosswind. When facing light crosswinds, the blades rotate at a small angle to allow airflow while simultaneously changing the direction of the crosswind. When facing heavy crosswinds, the blades rotate to be level with the wind direction, allowing the crosswind to pass directly through the gaps between the blades. This barrier can reduce the wind load force of heavy crosswinds on the louvered wind barrier, thereby reducing the force transmitted from the louvered wind barrier to the underlying bridge. However, it cannot reduce the overturning moment of trains in strong winds, and its structure is complex and its manufacturing cost is high. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a windbreak wall that can adjust its angle according to the actual wind and sand environment, thereby reducing the overturning moment of strong winds on the train, ensuring the safe operation of the train in strong wind and sand environments, and ensuring the safety of passengers.

[0005] According to the present invention, a windbreak wall includes a windbreak panel and an angle adjustment device. The windbreak panel is arranged on one or both sides of a railway bridge, with the leeward side of the windbreak panel facing the train. The angle adjustment device includes two columns respectively arranged on the left and right sides of the windbreak panel. The lower part of the windbreak panel is rotatably connected to the lower part of the columns. A motor is installed on the upper part of the columns. The output shaft of the motor faces the windbreak panel and is connected to a gear. Mounting plates are connected to the left and right sides of the upper part of the windbreak panel. The mounting plates are perpendicular to the windbreak panel. An arc-shaped rack is fixed to the mounting plate. The gear meshes with the arc-shaped rack to drive the windbreak panel to adjust its angle.

[0006] The windbreak wall according to the above embodiments of the present invention has at least the following beneficial effects:

[0007] Through the meshing of gears and an arc-shaped rack, when the motor drives the gears to rotate, the arc-shaped rack moves the mounting plate along an arc-shaped trajectory, thereby enabling the upper part of the windbreak wall to rotate with the lower part as the fulcrum, thus achieving angle adjustment. In severe windy and sandy environments, the windbreak walls on both sides of the railway bridge are tilted from the outside in, which can reduce the overturning moment of strong winds on the train, avoid threats such as overturning and derailment, and ensure the safe operation of the train in strong wind and sandy environments, thereby ensuring the safety of passengers. On the other hand, after the windbreak walls on both sides of the train are tilted, they can combine with the cross-section of the car body to form a windward shape with an isosceles trapezoidal cross-section, thereby optimizing the aerodynamic shape of the train body surface when encountering strong winds, effectively reducing the erosion of the train surface by wind and sand, thereby reducing the number of maintenance times and costs.

[0035] Reference Figures 1 to 4 According to the present invention, a windbreak wall includes a windbreak plate 100 and an angle adjustment device 200. The windbreak plate 100 is arranged on one or both sides of a railway bridge 300, with the leeward side 110 of the windbreak plate 100 facing the train 400. The angle adjustment device 200 includes two columns 210 respectively arranged on the left and right sides of the windbreak plate 100. The lower part of the windbreak plate 100 is rotatably connected to the lower part of the columns 210. A motor 220 is installed on the upper part of the columns 210. The output shaft of the motor 220 faces the windbreak plate 100 and is connected to a gear 230. Mounting plates 240 are connected to the left and right sides of the upper part of the windbreak plate 100. The mounting plates 240 are perpendicular to the windbreak plate 100. An arc-shaped rack 250 is fixed to the mounting plates 240. The gear 230 meshes with the arc-shaped rack 250 to drive the windbreak plate 100 to adjust the angle.

[0036] Specifically, through the meshing of gear 230 and arc-shaped rack 250, when motor 220 drives gear 230 to rotate, arc-shaped rack 250 drives mounting plate 240 to move along an arc-shaped trajectory, thereby enabling the upper part of the windbreak wall to rotate with the lower part as the fulcrum, thus achieving angle adjustment. In severe windy and sandy environments, the windbreak walls on both sides of the railway bridge 300 are tilted from the outside to the inside, which can reduce the overturning moment of strong winds on train 400, avoid threats such as overturning and derailment, and ensure the safe operation of train 400 in strong wind and sandy environments, thereby ensuring the safety of passengers. On the other hand, after the windbreak walls on both sides of train 400 are tilted, they can combine with the car body cross-section to form a windward shape with an isosceles trapezoidal cross-section, thereby optimizing the aerodynamic shape of the car body surface when encountering strong winds, effectively reducing the erosion of the train 400 surface by wind and sand, and reducing the wear between the wheels and rails, thereby reducing the number of maintenance times and lowering maintenance costs.

[0037] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, grooves are provided on both the left and right sides of the upper part of the wind deflector 100, and the mounting plate 240 can be fitted into the grooves. The mounting plate 240 can also be fixed to the wind deflector 100 by bolts 270 or hinges or other locking components, or by other fixing methods, which will not be described in detail here.

[0038] Reference Figure 2 and Figure 4 According to some embodiments of the present invention, the mounting plate 240 is provided with a downward-facing arc-shaped through groove 241, and the arc-shaped rack 250 is fixed to the bottom wall of the arc-shaped through groove 241. Specifically, the arc-shaped rack 250 can be fixed by providing a corresponding groove on the bottom wall of the arc-shaped through groove 241 and then embedding the arc-shaped rack 250 into the groove, or by fixing the two ends of the arc-shaped rack 250 with bolts 270, or other fixing methods, which will not be described in detail here.

[0039] Reference Figure 5 According to some embodiments of the present invention, the upper end surface of the mounting plate 240 is an arc-shaped surface adapted to the arc-shaped rack 250, and the arc-shaped rack 250 is fixed to the upper end surface of the mounting plate 240. Specifically, the arc-shaped rack 250 can be fixed by providing a corresponding groove on the arc-shaped surface and then embedding the arc-shaped rack 250 into the groove, or by fixing the two ends of the arc-shaped rack 250 with bolts 270, or other fixing methods, which will not be elaborated here.

[0040] Reference Figure 3 and Figure 6According to some embodiments of the present invention, the upper part of the column 210 is provided with a mounting groove 213, the opening of the mounting groove 213 facing the mounting plate 240, and the motor 220 is fixed to the bottom of the mounting groove 213 by a locking member. Specifically, the locking member includes a bolt 270, the bottom of the motor 220 is provided with a bracket 221, the bracket 221 is provided with a through hole, and the bottom wall of the mounting groove 213 is provided with a positioning hole corresponding to the through hole. The bolt 270 passes through both the through hole and the positioning hole to fix the bracket 221, thereby fixing the motor 220. The locking member can also be a hinge, etc., which will not be described in detail here. Furthermore, the motor 220 can also be fixed to the outer wall of the column 210 by the locking member, which will not be described in detail here.

[0041] Reference Figure 3 and Figure 7 According to some embodiments of the present invention, the lower part of the column 210 is provided with a mounting hole 211, and a bearing 212 is installed in the mounting hole 211. Movable columns 120 are connected to both the left and right sides of the lower part of the baffle plate 100. The movable columns 120 extend horizontally, with one end of the movable column 120 fixed to the baffle plate 100 and the other end connected to the bearing 212. Specifically, by fixing the movable column 120 connected to the bearing 212 to the lower part of the baffle plate 100, the upper part of the baffle plate 100 can rotate with the movable column 120 as a fulcrum, while the movable column 120 can also provide support.

[0042] Reference Figure 8 and Figure 9 According to some embodiments of the present invention, a support plate 260 is connected to the lower part of the column 210. The support plate 260 is perpendicular to the wind deflector 100. The support plate 260 is provided with an arc-shaped sliding groove 261, which corresponds to the arc-shaped rack 250. A rotating shaft 130 is connected to both the left and right sides of the lower part of the wind deflector 100. The rotating shaft 130 extends in the horizontal direction. One end of the rotating shaft 130 is fixed to the wind deflector 100, and the other end of the rotating shaft 130 is rotatably connected to a roller 140, which slides in the arc-shaped sliding groove 261. Specifically, the concave opening of the arc-shaped rack 250 faces downwards, while the concave opening of the arc-shaped groove 261 faces upwards. Since the lower part of the wind deflector 100 is fixedly connected to the rotating shaft 130, and the other end of the rotating shaft 130 is rotatably connected to the roller 140 sliding on the arc-shaped groove 261, when the motor 220 drives the gear 230 to rotate, and the arc-shaped rack 250 drives the upper part of the wind deflector 100 to rotate, it will force the lower part of the wind deflector 100 to rotate in the opposite direction along the arc-shaped groove 261. The roller 140 makes the rotation process smoother, and at the same time, the roller 140 can play a supporting role.

[0043] Furthermore, according to some embodiments of the present invention, the windbreak wall also includes a central control console, which is equipped with a control system. The control system can communicate with the motor 220 and control the start and stop of the motor 220 to achieve remote control. Furthermore, the windbreak wall is also equipped with a wind speed sensor, which can be installed on the windward side of the windbreak 100 to monitor changes in wind force in real time. The wind speed sensor can communicate with the control system to transmit wind speed change information to the control system in real time. The control system controls the start and stop of the motor 220 according to the received signal to achieve angle adjustment of the windbreak 100, eliminating the need for manual angle adjustment, resulting in high work efficiency and flexibility.

[0044] In this embodiment of the invention, the connector can be a clip or a plate of other shapes, and the connection method can be a snap fastener, screw fastening or welding, etc., which will not be described in detail here.
