Description

Technical Field

[0001] This utility model relates to the field of traffic engineering technology, and in particular to a windbreak device for highway bridges. Background Technology

[0002] Highway bridges are linear structures that span obstacles such as rivers, valleys, and roads to provide passage for highway traffic. They consist of a superstructure, substructure, and foundation, and must meet design requirements for vehicle load, pedestrian passage, wind resistance, and earthquake resistance. They are key nodes in the highway transportation network. Highway bridges need to block the wind. In strong winds, vehicles on the bridge deck are easily affected by lateral wind forces, which can cause vehicles to deviate, become difficult to control, or even overturn. This is especially true for large trucks, high-speed vehicles, and bridges spanning rivers and seas, where wind loads can cause bridge structural vibrations, affecting driving safety and bridge lifespan. By installing windbreaks on both sides of the bridge, wind speed on the bridge deck can be reduced, the lateral force of wind loads on vehicles can be reduced, and the airflow field can be optimized to suppress bridge structural vibrations. This is an important engineering measure to ensure the safe passage of highway bridges in strong wind areas. Especially in windy sections such as coastal and mountainous areas, windbreak design plays a crucial role in improving the wind resistance stability and driving safety of bridges.

[0003] During the use of existing highway bridges, strong winds pose a serious threat to driving safety. Traditional windbreak devices are usually fixed structures, which are difficult to adapt to changing wind force and direction, and their stability is poor, affecting service life and safety.

[0004] Therefore, a windbreak device for highway bridges is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a windbreak device for highway bridges, which can solve the problem that strong winds pose a serious threat to driving safety during the use of existing highway bridges. Traditional windbreak devices are usually fixed structures, which are difficult to adapt to changing wind force and direction, and have poor stability, affecting service life and safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a windbreak device for highway bridges, comprising a protective structure, wherein a shielding structure is bolted to the right side of the protective structure;

[0007] The shielding structure includes a barrier panel, a mounting base, a torsion spring, a fixing rod, a windbreak plate, and a fixing plate. The top of the barrier panel is fixedly connected to the bottom of the fixing plate. The right side of the barrier panel is bolted to the left side of the mounting base. The inner wall of the mounting base is rotatably connected to the outer wall of the fixing rod. The front side of the mounting base is bolted to the rear side of the torsion spring. The inner wall of the torsion spring is fixedly connected to both sides of the outer wall of the fixing rod. The right side of the outer wall of the fixing rod is fixedly connected to the left side of the windbreak plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A windbreak device for highway bridges includes a protective structure 1, with a shielding structure 2 bolted to the right side of the protective structure 1.

[0027] The shielding structure 2 includes a baffle plate 21, a mounting base 22, a torsion spring 23, a fixing rod 24, a windbreak plate 25, and a fixing plate 26. The top of the baffle plate 21 is fixedly connected to the bottom of the fixing plate 26. The right side of the baffle plate 21 is bolted to the left side of the mounting base 22. The inner wall of the mounting base 22 is rotatably connected to the outer wall of the fixing rod 24. The front side of the mounting base 22 is bolted to the rear side of the torsion spring 23. The inner wall of the torsion spring 23 is fixedly connected to both sides of the outer wall of the fixing rod 24. The right side of the outer wall of the fixing rod 24 is fixedly connected to the left side of the windbreak plate 25.

[0028] In this embodiment: a shielding structure 2 is provided, in which the baffle plate 21 forms the main body of the shielding structure 2, creating a wind barrier. The mounting base 22 serves as the mounting carrier for the fixed rod 24 and the torsion spring 23. The torsion spring 23 generates restoring force through its elastic deformation. When the wind force acts on the wind deflector 25 and causes the fixed rod 24 to rotate, the torsion spring 23 stores elastic potential energy. When the wind force weakens or the wind direction changes, the torsion spring 23 releases its potential energy, causing the fixed rod 24 and the wind deflector 25 to automatically reset, ensuring that the wind deflector 25 is always in a stable position. The optimal windbreak position enhances the adaptability of the windbreak device. The fixed rod 24 is a key component connecting the mounting base 22 and the wind deflector 25. The wind deflector 25, as a component that directly blocks the wind force, is numerous and evenly distributed on the outer wall of the fixed rod 24, forming a large-area windbreak barrier, reducing wind speed and minimizing the impact of wind on vehicles on highway bridges. The fixed plate 26 is arc-shaped, and through a smoothly transitioned curved surface, it guides the airflow along the arc direction, reducing airflow separation and lowering the drag coefficient of the barrier plate 21.

[0029] Specifically, such as Figure 3 , Figure 5 As shown, the protective structure 1 includes a fixed railing 11, the right side of which is bolted to the left side of the enclosure 21.

[0030] Specifically, such as Figure 3 , Figure 5 As shown, a connecting rod 12 is fixedly connected to the left side of the fixed railing 11, and an arc-shaped plate 13 is bolted to the left side of the connecting rod 12.

[0031] Specifically, such as Figure 3 , Figure 5 As shown, a mounting post 14 is fixedly connected to the bottom of the fixed fence 11, and a support member 15 is fixedly connected to the bottom right side of the fixed fence 11. The top of the support member 15 is bolted to the bottom of the fence panel 21.

[0032] In this embodiment: a protective structure 1 is set up, in which the fixed railing 11 serves as the core of the protective structure 1, bearing the weight of the shielding structure 2 and the force of the wind on the device. The connecting rod 12 serves as the rod body for the arc plate 13 to be installed in conjunction with the fixed railing 11. When a vehicle collides with the bridge, the arc plate 13 can first bear part of the collision energy, and reduce the collision force through its own deformation and buffering effect. The mounting column 14 serves as the base for the installation of the fixed railing 11, firmly fixing the fixed railing 11 to the highway or bridge, and bearing the weight and wind force of the entire windbreak device.

[0033] Specifically, such as Figure 1 , Figure 3 , Figure 5As shown, a rectangular plate 3 is fixedly connected to the outside of the mounting column 14. The rectangular plates 3 are numerous and evenly distributed on the outside of the mounting column 14.

[0034] Specifically, such as Figure 1 , Figure 4 As shown, connecting posts 4 are fixedly connected to both sides of the right side of the fixed fence 11, and the right side of the connecting posts 4 is bolted to the left side of the fence 21.

[0035] In this embodiment: by setting a rectangular plate 3 in conjunction with the mounting column 14 as the base for installing the fixed railing 11, after the mounting column 14 is buried underground, the rectangular plate 3 increases the contact area, so that the shielding structure 2 is stably supported as a whole. The connecting column 4 serves as the pole for the protective structure 1 and the shielding structure 2 to be installed together, thereby improving the wind resistance of the device in strong wind environments.

[0036] Specifically, such as Figure 1 , Figure 4 , Figure 5 As shown, a mounting rod 5 is bolted to the front side of the fixed railing 11. There are two mounting rods 5, which are respectively set on the front side and the rear side of the fixed railing 11.

[0037] Specifically, such as Figure 4 , Figure 5 As shown, there are three connecting rods 12 evenly distributed on the left side of the fixed railing 11, and several windbreak plates 25 evenly distributed on the outer wall of the fixed rod 24.

[0038] In this embodiment: the mounting rod 5 is provided for connecting several devices, and the three connecting rods 12 are provided to increase the stability of the arc plate 13 and the connecting rods 12 during installation.

[0039] Working principle: This windbreak device for highway bridges firstly secures the fixed railing 11 of the protective structure 1 to the highway or bridge via the mounting column 14 and rectangular plate 3, bearing the weight of the entire device and wind force. The connecting rod 12 and the arc plate 13 work together to buffer the impact of vehicle collisions. The mounting rod 5 can connect multiple sets of devices. When strong winds strike, the barrier plate 21 and the fixed plate 26 in the shielding structure 2 form a basic windbreak barrier. The arc design of the fixed plate 26 guides the airflow and reduces the wind resistance coefficient. When the wind force acts on the windbreak plate 25, it causes the fixed rod 24 to rotate within the mounting base 22, driving the torsion spring 2. 3. Elastic deformation occurs and potential energy is stored. At this time, the angle of the wind deflector 25 changes. Under the balance of wind force and torsion spring force, a reasonable wind-blocking angle is formed, which effectively weakens the wind force. When the wind force weakens or the wind direction changes, the torsion spring 23 releases the stored elastic potential energy, which drives the fixed rod 24 and the wind deflector 25 to automatically reset, ensuring that the wind deflector 25 is always in the best wind-blocking position and continuously resists wind force from different directions. The support 15 firmly connects the enclosure 21 and the fixed railing 11. The connecting column 4 enhances the connection strength between the protective structure 1 and the shielding structure 2. Multiple components work together to achieve continuous and effective wind protection for vehicles on highway bridges.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
