Description

Technical Field

[0001] The invention relates to the technical field of bridge windshields, and in particular to a bridge windshield device with adjustable height and porosity. Background Art

[0002] In recent years, accidents of vehicles on the bridge deck rolling over due to high-speed crosswinds have occurred frequently, seriously affecting the safety of vehicles on the bridge. At present, the traffic management department mainly adopts management measures such as limiting speed standards and closing traffic to reduce the impact of crosswinds on vehicles on the bridge deck. However, these two measures are mainly determined by subjective judgment and experience, lacking scientific theoretical basis and data support. If speed limits and traffic closure measures are blindly formulated, it will not only threaten vehicle safety and bridge traffic efficiency, but also cause huge economic losses and bring adverse social impacts.

[0003] In order to ensure the safety of vehicles traveling on bridges or on the ground, bridge windshields have become one of the widely used windbreak measures in current projects. Bridge windshields mainly include barrier strip type and plate-drilled hole type. The plate-drilled hole scheme has a better windbreak effect than the barrier strip type windshield, especially the plate-drilled circular hole scheme has a significantly better shielding effect than the barrier strip type windshield in the area sensitive to vehicle lift, that is, the ground layer. At present, the barrier strip type windshield is mainly used in actual engineering applications, and the plate-drilled hole type is less used. Therefore, it is of great significance to strengthen the application of the plate-drilled circular hole type windshield; in addition, the windshields currently used are mainly in the form of fixed height and porosity. On the one hand, in windy weather, they cannot provide sufficient windbreak effect for bridge deck driving, affecting the safety of bridge deck vehicles; on the other hand, in light wind weather, they affect the driver's line of sight and the urban landscape. Therefore, it is of great significance to study the variable height and variable porosity plate-drilled circular hole windshield device. Summary of the invention

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1-Figure 7As shown: This embodiment provides a bridge windshield device with adjustable height and porosity, including a windshield module, the windshield module including a frame 1 and a windshield belt 2, the frame 1 is provided with a roller 3 rotatably connected to the frame 1, the roller 3 is used to support the windshield belt 2, both ends of the frame 1 are provided with lifting devices, the lifting devices are used to realize the lifting and lowering of the roller 3, both sides of the frame 1 are provided with windshield belt retracting and releasing devices, one end of the windshield belt 2 is wrapped around one windshield belt retracting and releasing device, the other end of the windshield belt 2 is wrapped around another windshield belt retracting and releasing device, and the windshield belt 2 is provided with through holes 16 of different sizes. The windshield belt retracting and extending device of the present embodiment realizes the retraction and extension of the windshield belt 2, and the windshield belt 2 is provided with through holes 16 of different sizes, which can change the size of the through holes 16 on the windshield belt 2 that completes the windshield function. The lifting device realizes the lifting and lowering of the windshield belt 2, so that the windshield belt 2 can achieve height changes. The present embodiment can realize two-way adjustment of the size and height of the through holes 16 of the windshield belt 2 to adapt to different weather. The present embodiment expands the scope of use of the bridge windshield barrier, so that the bridge windshield barrier can ensure a good windshield effect under different conditions.

[0031] In this embodiment, each lifting device includes a lifting rod 4, a driving device and a transmission device. The upper end of the lifting rod 4 is fixedly connected to a bracket 5, and the bracket 5 is rotatably connected to both ends of the drum 3. The driving device drives the lifting rod 4 to rise and fall through the transmission device.

[0032] In this embodiment, the transmission device includes a driving wheel 6, a first guide wheel 7, a second guide wheel 8 and a rope 9. Each lifting rod 4 is inserted into a sleeve on the frame 1. The lower end of the lifting rod 4 is rotatably connected to the first guide wheel 7. The driving wheel 6 and the second guide wheel 8 are both rotatably connected to the frame 1. One end of the rope 9 is fixed to the frame 1. The other end of the rope 9 passes through the first guide wheel 7, the second guide wheel 8 and the driving wheel 6 in sequence and is fixedly connected to the driving wheel 6. The driving device is fixedly connected to the driving wheel 6 and drives the driving wheel 6 to rotate. The fixed end of the rope 9, the first guide wheel 7 and the second guide wheel 8 are arranged in a "V" shape, and the first guide wheel 7, the second guide wheel 8 and the driving wheel 6 are arranged in a "V" shape.

[0033] In this embodiment, the driving device includes a first motor 10 and a transmission rod 11. The first motor 10 is fixed on the frame 1. The transmission rod 11 is fixedly penetrated at the center of the two driving wheels 6 and is fixedly connected by a key. The output end of the first motor 10 is connected to the transmission rod 11 through a coupling. The output end of the first motor 10 drives the transmission rod 11 to rotate and then drives the driving wheel 6 to rotate.

[0034] The output end of the first motor 10 of this embodiment outputs power to the driving wheel 6 through the transmission rod 11. Figure 3As shown in the figure, the driving wheel 6 rotates clockwise, so that the rope 9 is wound around the driving wheel 6, and the rope 9 drives the second guide wheel 8 to rotate. The second guide wheel 8 drives the first guide wheel 7 to rotate through the rope 9. Since the rope 9 is wound around the driving wheel 6, the rope 9 is shortened, and the rope 9 pushes the lifting rod 4 to rise along the sleeve, so that the windshield belt 2 rises. On the contrary, the driving wheel 6 rotates clockwise, so that the rope 9 is wound around the driving wheel 6. Figure 3 As shown in FIG. , the windshield belt 2 is rotated counterclockwise to achieve the lowering of the windshield belt 2.

[0035] In this embodiment, the windshield belt retracting and releasing device includes a second motor 12, a first synchronous wheel 13, a second synchronous wheel 14 and a winding roller 15. The second motor 12 is fixed on the frame 1, and the output end of the second motor 12 is fixedly connected to the center of the first synchronous wheel 13. The first synchronous wheel 13 and the second synchronous wheel 14 are connected through a synchronous belt transmission. Both ends of the winding roller 15 are rotatably connected to the frame 1 and fixedly connected to the center of the second synchronous wheel 14. The windshield belt 2 is wound around the winding roller 15.

[0036] In this embodiment, the sizes of the plurality of through holes 16 on the windshield belt 2 gradually increase from one end of the windshield belt 2 to the other end of the windshield belt 2. Specifically, the plurality of through holes 16 are arranged in a matrix, the sizes of the plurality of through holes 16 in the same column along the width direction of the windshield belt 2 are the same, and the sizes of the plurality of through holes 16 in the same row along the length direction of the windshield belt 2 increase in sequence. The windshield belt 2 is provided with a plurality of reinforcing ribs 17, and each reinforcing rib 17 is evenly arranged along the length direction of the windshield belt 2.

[0037] In this embodiment, a base 18 is fixedly connected to one side of the frame 1. The base 18 is arranged on the side with a larger size of the through hole 16. A plurality of mounting holes are arranged on the base 18. The base 18 is fixed to the bridge through the plurality of mounting holes.

[0038] This embodiment also includes an anemometer 22, a weighing module 21, a high-definition capture module 20 and a data processing and control module. The anemometer 22 and the wind barrier module 23 are both arranged on both sides of the bridge 19. The anemometer 22 is arranged on the outside of the wind barrier module 23. The high-definition capture module 20 and the weighing module 21 are both arranged on the bridge 19. The anemometer 22 is used to detect wind speed and wind direction data. The weighing module 21 is used to detect vehicle weight. The weighing module 21 is preferably a vehicle weighing scale. The high-definition capture module 20 is used to obtain vehicle height, license plate and speed data. The high-definition capture module 20 is preferably an industrial camera. The data processing and control module is electrically connected to the anemometer 22, the weighing module 21, the high-definition capture module 20 and the wind barrier module 23 respectively. The data processing and control module adjusts the height and porosity of the wind barrier module 23 according to the data detected by the anemometer 22, the weighing module 21 and the high-definition capture module 20.

[0039] When the windshield module 23 of the present embodiment is in use, the high-definition capture module 20 on the bridge 19 detects the vehicle height, license plate and speed data of the vehicle; the weighing module 21 on the bridge 19 weighs the vehicle on the bridge 19 and detects the vehicle weight data; the anemometers 22 on both sides of the bridge 19 measure the wind speed and wind direction data in real time, and transmit the data measured by the high-definition capture module 20, the weighing module 21 and the anemometer 22 to the data processing and control module, and the data processing and control module processes the data through the high-definition capture module 20, the weighing module 21 and the anemometer 22. The measured data is analyzed to obtain the height and porosity of the windshield required for the vehicle on the bridge 19 to realize the windshield function. Accordingly, the data processing and control module outputs a signal to the windshield module 23 of this embodiment, and adjusts the height and porosity of the windshield belt 2 to meet the windshield function of vehicles with different speeds and weights under different wind speed conditions. When the windshield belt 2 is adjusted to an appropriate height and porosity, the first motor 10 and the second motor 12 are in a brake state to prevent the wind from blowing the windshield belt 2 and causing the height and porosity of the windshield belt 2 to change. Specifically, the adjustment values ​​of the height and porosity of the windshield module 23 are shown in Tables 1 and 2. A high porosity corresponds to a larger size of the through hole 16 of the windshield belt 2, and a low porosity corresponds to a smaller size of the through hole 16 of the windshield belt 2.

[0040] Specifically, the height of the windshield module 23 is adjusted based on the vehicle height and the measured wind speed. When the wind speed is low, the height of the windshield structure is 0, that is, the windshield module 23 is not raised. Under other wind speed conditions, the height is adjusted accordingly based on the maximum value of the vehicle height measured every 10 minutes. If the real-time vehicle height value is greater than the currently set windshield height, the windshield height value is adjusted immediately. The specific adjustment values ​​are shown in Table 1.

[0041] Table 1 Statistics of windshield height adjustment values

[0042]

[0043] The porosity adjustment of the windshield module 23 takes into account the measured wind speed and vehicle load, and the specific adjustment values ​​are shown in Table 2.

[0045]

[0046] The present embodiment further includes a weather forecast module, which is used to detect weather data. The data processing and control modules are electrically connected to the weather forecast modules respectively. The data processing and control modules pre-adjust the height and porosity of the windshield module 23 according to the data detected by the weather forecast module.

[0047] This embodiment aims to improve the device structure, and the data collection and control process are existing technologies.

The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope.
