Description

Technical Field

[0001] This invention belongs to the technical field of wind and snow protection transportation facilities, and specifically relates to an intelligent adjustable wind and snow protection device. Background Technology

[0002] Snowstorms are a major natural disaster affecting roads, primarily occurring in high-altitude, wind-prone areas of Northeast and Northwest my country. Snowflow disasters are widespread and frequent, generally occurring when snowfall exceeds a certain depth. When blowing snow occurs, the impact on road traffic is mainly reflected in two aspects: firstly, visibility is impaired, greatly increasing the risk of traffic accidents; secondly, snow accumulation on the road surface due to road cross-sectional characteristics obstructs traffic, often requiring significant manpower and resources for snow removal, thus reducing road efficiency.

[0003] Measures to prevent snowstorms along transportation routes can be broadly categorized into the following aspects: controlling snow supply, improving incoming wind direction, increasing road surface wind speed, and improving airflow patterns. Currently, snow and wind protection devices are widely used in practical engineering projects, such as snow barriers, snow walls, and snow-proof forests. These measures are quite effective in actual use, but their drawbacks cannot be ignored. For example, snow barriers need to be a certain distance from the shoulder to be effective, allowing snow particles to settle in front of the road. However, this is a significant drawback for some special areas where a greater distance cannot be provided. Snow walls need to be erected near the shoulder to block crosswinds and snowfall, causing snow particles to fall in front of the wall. However, snow walls require a large amount of concrete or other steel materials, and their construction on the roadside severely obstructs driving and viewing routes, limiting their use to important road sections with significant disaster impacts. Snowbreak forests are groups of trees planted along the roadside that stabilize the soil and prevent snow from entering the road. However, snowbreak forests require year-round planting and must consider survival rates, and in areas with severe soil erosion, they require substantial manpower and resources.

[0004] Furthermore, existing wind deflectors mostly employ a downward wind deflection system, compressing the incoming airflow to create an acceleration effect. In current engineering practice, wind deflectors are often fixed installations, typically positioned on the side of the road parallel to the direction of traffic, perpendicular to or at a certain angle to the road surface. This configuration makes it impossible to adjust the angle of the wind deflector according to the magnitude of the incoming wind speed, and the acceleration area is very limited, resulting in inconsistent acceleration effects. There is still a significant chance of snow accumulation on the road surface, and in some cases, it may even lead to an increase in snow accumulation. Additionally, due to wind loads, the deflector surface is highly susceptible to breakage under strong winds, easily causing damage to the device. Summary of the Invention

[0005] To address the above problems, this invention provides an intelligent adjustable snow and wind protection device that can adjust the extension, retraction, and tilt angle of the wind guide plate according to changes in wind speed, thereby improving the snow blowing effect, expanding the wind guiding range, and achieving a better snow and wind protection effect.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An intelligent adjustable wind and snow protection device includes several columns spaced apart on both sides of a road. A telescopic wind guide component is provided between every two adjacent columns. A drive device is provided inside each column to drive the telescopic wind guide component to extend and retract and adjust its tilt angle. A controller is provided inside each column. An anemometer and a wind direction indicator are provided on the top of each column. The anemometer, wind direction indicator, and drive device are all connected to the controller, which can control the tilt angle and unfolded area of ​​the telescopic wind guide component according to the wind speed.

[0007] Furthermore, the telescopic air guide assembly includes a telescopic rod and a foldable air guide plate assembly. The fixed end of the air guide plate assembly and the telescopic rod is connected to a column on one side. The other end of the air guide plate assembly is connected to the movable end of the telescopic rod. The other end of the air guide plate assembly is connected to a drive device inside the columns on both sides via ropes. The drive devices inside the columns on both sides drive the extension and retraction of the air guide plate assembly and adjust its tilt angle. The telescopic rod and the rope are arranged side by side on the same side of the air guide plate assembly.

[0008] Furthermore, the air guide plate assembly includes multiple air guide plates connected in sequence, with the junctions of the multiple air guide plates being connected to the telescopic rod at intervals, and adjacent air guide plates being rotatably connected by a connector.

[0009] Furthermore, the air guide plate connected to the telescopic rod has threaded holes on its edge, which are used for the rope to pass through and for fixing the end of the rope; the upper and lower edges of the air guide plate are respectively provided with threaded holes.

[0010] Furthermore, the telescopic rod includes several telescopic sections that are sequentially fitted inside and out. Each telescopic section has a short connecting rod at its free end. The short connecting rod at the end of the innermost telescopic section is rotatably connected to the edge of the end air guide plate. The remaining telescopic sections have notches on the side facing the air guide plate for the short connecting rod to pass through. The telescopic rod is located in the middle of the air guide plate and between the upper and lower ropes. The fixed end of the outermost telescopic section is connected to the first air guide plate. The short connecting rod at the end of the middle telescopic section is rotatably connected to the connector at the junction of the corresponding air guide plate.

[0011] Furthermore, the driving device includes a mounting plate, a first motor, a drive shaft, and two pulleys. The two pulleys are respectively located at the upper and lower ends of the mounting plate, and the ropes wound on the two pulleys are respectively connected to the air guide plate assembly on the side of the column. The drive shaft is vertically located in the middle of the mounting plate, and both ends of the drive shaft extend to the outside of the mounting plate and are respectively fixedly connected to the two pulleys. The drive shaft is driven by the first motor. The mounting plate is connected to a swing mechanism, and the middle of the mounting plate is connected to the inner wall of the column through a support shaft. The swing mechanism drives the mounting plate and the air guide plate assembly to swing between a vertical state and an inclined state.

[0012] Furthermore, the support shaft is installed through the column, and the outer end of the support shaft is connected to the telescopic rod.

[0013] Furthermore, the oscillation mechanism includes a second motor, a cable shaft, and a cable. The second motor is located at the bottom of the column. The cable shaft is coaxially fixed with the output shaft of the second motor. The cable is wound around the cable shaft. One end of the cable is connected to the lower end of one side of the mounting plate, and the other end of the cable is connected to the upper end of the opposite side of the mounting plate.

[0014] Furthermore, multiple sets of the telescopic air guide assembly and driving device are arranged side by side from top to bottom. The upper and lower pulleys of each mounting plate are connected to the air guide plate group in the same row on the side of the column by ropes. One end of the cable is connected to the lower end of the same side of multiple mounting plates in sequence, and the other end of the cable is connected to the upper end of the opposite side of the mounting plates in sequence.

[0015] Furthermore, the column is equipped with a storage battery inside, and a photovoltaic panel is provided on the top of the column to power the storage battery. The storage battery is used to provide power to the anemometer, wind direction indicator, drive device and controller.

[0016] The technological advancements achieved by this invention compared to existing technologies are as follows: This invention involves installing several pillars at intervals along both sides of the road. Wind speed and direction are detected by anemometers and wind vanes located at the top of each pillar. A controller operates the internal drive mechanism of each pillar based on the wind speed and direction, adjusting the tilt angle and unfolded area of ​​the telescopic wind-guiding components between the pillars. When the frontal wind speed is high, the strong wind is sufficient to blow snow away; when the wind speed is low, snow accumulation on the road surface is minimal, and the wind vanes do not need to be opened. When the frontal wind speed is in the medium speed range, the wind vanes open under the operation of the drive mechanism, controlling their rotation to the corresponding angle to fully utilize their snow-blowing capacity, enhancing the snow-blowing range and effect. At this time, the presence of the wind vanes reduces the impact of crosswinds on vehicles. Attached Figure Description

Detailed Implementation

[0019] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0020] like Figure 1 , Figure 2 As shown, an intelligent adjustable wind and snow protection device includes several columns 1 spaced apart on both sides of a road. A telescopic wind guide assembly is installed between every two adjacent columns 1. A drive device is installed inside each column 1 to drive the telescopic wind guide assembly to extend and retract and adjust its tilt angle. A controller is installed inside each column 1. An anemometer 2 and a wind vane 3 are installed on the top of each column 1. The anemometer 2, wind vane 3, and drive device are all connected to the controller (not shown in the figure), and can control the tilt angle and unfolded area of ​​the telescopic wind guide assembly according to the wind speed. After the anemometer and wind vane measure the wind speed and direction in the wind field and transmit this data to the controller, the controller calculates the wind speed perpendicular to the wind guide plate at that moment, called the forward wind speed. The magnitude of the forward wind speed is directly related to the operating state of the device. When the wind speed in the front direction is high or low, it is difficult for snow to accumulate on the road surface, and the wind deflector does not need to be opened; when the wind speed in the front direction is in the medium wind speed range, the wind deflector will open and rotate at a certain angle under the operation of the drive device to enhance the snow blowing range and snow blowing effect; at the same time, it can also reduce the impact of crosswinds on vehicles.

[0021] In one specific embodiment of the present invention, such as Figure 1 , 7 As shown, the telescopic air guide assembly includes a telescopic rod 8 and a foldable air guide plate assembly. The fixed end of the air guide plate assembly and the telescopic rod 8 is connected to a side column 1. The other end of the air guide plate assembly is connected to the movable end of the telescopic rod 8, and the other end of the air guide plate assembly is connected to a drive device inside the two side columns 1 via ropes 4. The drive devices inside the two side columns 1 drive the extension and retraction of the air guide plate assembly and adjust its tilt angle. The telescopic rod and the ropes 4 are arranged side by side on the same side of the air guide plate assembly. The air guide plate assembly includes multiple air guide plates 5 connected in sequence. The junctions of the multiple air guide plates 5 are connected to the telescopic rod at intervals. Adjacent air guide plates 5 are rotatably connected by a connector 6. Figure 11 As shown.

[0022] like Figure 7 , 8As shown, in the specific design, the edge of the air guide plate 5 connected to the telescopic rod 8 is provided with a threading hole 7, which is used for the rope 4 to pass through and for fixing the end of the rope 4; the upper and lower edges of the air guide plate 5 are respectively provided with threading holes 7. The telescopic rod 8 includes several telescopic joints that are sequentially fitted inside and out. Each telescopic joint has a shorting rod 9 at its free end. The shorting rod 9 at the end of the innermost telescopic joint is rotatably connected to the edge of the end air guide plate 5. The remaining telescopic joints have notches on the side facing the air guide plate 5 for the shorting rod 9 to pass through. The telescopic rod 8 is located in the middle of the air guide plate 5 and between the upper and lower ropes. The fixed end of the outermost telescopic joint is connected to the first air guide plate 5, and the shorting rod 9 at the end of the middle telescopic joint is rotatably connected to the connector 6 at the junction of the corresponding air guide plate 5. The end of the transverse rope passes through the air guide plate at its free end. The pads fixed to the rope are located on both sides of the air guide plate. When the rope extends or retracts, the pads connected to the rope can drive the air guide plate to move. The rope passing through the threaded hole can support and guide the air guide plate, while the telescopic rod also provides some support for the air guide plate.

[0023] In one specific embodiment of the present invention, such as Figure 3-5 As shown, the driving device includes a mounting plate 10, a first motor 11, a drive shaft 12, and two pulleys 13. The two pulleys 13 are respectively located at the upper and lower ends of the mounting plate 10. The ropes 4 wound on the two pulleys 13 are respectively connected to the air guide plate assembly on the side of the column 1. The drive shaft 12 is vertically located in the middle of the mounting plate 10. Both ends of the drive shaft 12 extend to the outside of the mounting plate 10 and are respectively fixed to the two pulleys 13. The drive shaft 12 is driven by the first motor 11. The mounting plate 10 is connected to a swing mechanism. The middle of the mounting plate 10 is connected to the inner wall of the column 1 through a support shaft 14. The swing mechanism drives the mounting plate 10 and the air guide plate assembly to swing between a vertical state and an inclined state. When the mounting plate 10 is inclined, the mounting plate 10 rotates around the support shaft 14. The first motor is controlled by a controller to rotate. The first motor drives the drive shaft and the upper and lower pulleys to rotate simultaneously. The ropes on both sides connected to the free ends of the air guide plates are synchronously wound and released as the pulleys on both sides rotate. For example: The left side of the air guide plate assembly is connected to the left column. When the left pulley rotates to tighten the left rope, the right pulley rotates to release the right rope, allowing the air guide plates to be folded and retracted one by one, finally reaching the left column. Conversely, the air guide plates can be opened one by one. The pulleys on the mounting plate inside the column in the middle section are equipped with two parallel grooves, facilitating the simultaneous winding of ropes on both sides, enabling the pulley rotation to synchronously retract and release the ropes on both sides.

[0024] When wind and snow arrive, the anemometer measures the wind speed, the wind vane measures the wind direction, and the controller intelligently controls the equipment based on the data. When the wind speed is in the low-speed range, the wind guide plate is in a retracted state; when the wind speed exceeds this range and is relatively stable, the drive device drives the wind guide plate to unfold, and the oscillating mechanism inside the column drives the wind guide plate to rotate (as shown in the attached image). Figure 4 The air guide plates create air vents, and the bottom gap works together with the air vents to ensure the air guiding effect while increasing the air guiding area. As the wind speed changes, the air guide plates rotate to a suitable angle. When the wind speed reaches a high speed, the drive device controls the air guide plates to retract, relying on natural airflow to blow away the snow.

[0025] In the specific production process, such as Figure 7 , 8 As shown, the support shaft 14 passes through the column 1, and its outer end is connected to the telescopic rod 8. The support shaft provides an inclined fulcrum for the internal mounting plate and provides mounting support for the outer telescopic rod.

[0026] In one specific embodiment of the present invention, such as Figure 6 As shown, the tilting mechanism includes a second motor 15, a cable shaft 16, and a cable 17. The second motor 15 is located at the bottom of the column 1. The cable shaft 16 is coaxially fixed with the output shaft of the second motor 15. The cable 17 is wound around the cable shaft 16. One end of the cable 17 is connected to the lower end of one side of the mounting plate 10, and the other end of the cable 17 is connected to the upper end of the opposite side of the mounting plate 10. The controller and battery can be integrated into the second motor, which is fixed to the bottom of the column with bolts. The second motor is controlled by the controller and can be a servo motor. The forward and reverse rotation of the second motor drives the cable shaft to rotate, causing the height position of both ends of the cable to change, thereby driving the mounting plate to tilt. After the mounting plate tilts, the pulleys at its upper and lower ends cause the rope to deflect, thereby causing the wind guide plate to tilt synchronously. When snowstorms occur, the wind guide plate can switch and rotate between an upright position and various tilt angles according to the wind speed, maximizing the snow blowing effect and strengthening the wind guiding range.

[0027] As a preferred structure, such as Figure 1 , 9As shown, multiple sets of the telescopic air guide assembly and driving device 8 are arranged side by side from top to bottom. The upper and lower pulleys of each mounting plate 10 are connected to the air guide plate group on the same side of the column 1 via ropes 4. One end of the cable 17 is connected to the rotating ear plate 20 at the lower end of the same side of multiple mounting plates 10 in sequence, and the other end of the cable 17 is connected to the rotating ear plate 20 at the upper end of the opposite side of the mounting plate 10 in sequence. The second motor drives all the mounting plates inside the column to switch between upright and tilted states, and the ropes wound on the pulleys at both ends of all the mounting plates drive all the external air guide plates to switch between upright and tilted states. The first motor on all the mounting plates operates synchronously, driving the pulleys at both ends of the mounting plates to rotate synchronously, realizing the synchronous retraction and extension of multiple sets of air guide plates. This structure can utilize multiple sets of air guide plates to increase the air guiding area and improve the snow blowing effect.

[0028] In specific design, such as Figure 10 As shown, scissor-type telescopic components 18 are provided between adjacent upper and lower air guide plate groups. One end of the scissor-type telescopic component 18 is connected to the column 1, and the other end is connected to the free end of the air guide plate 5. The middle parts of multiple scissor-type telescopic components 18 and telescopic rods 8 are all connected to support rods 21. As the air guide plates unfold and retract, the scissor-type telescopic components also unfold and retract, providing support for the ends of the air guide plates. The telescopic rods and scissor-type telescopic components can distribute the weight of the air guide plates and the external forces they experience to the column. Figure 11 As shown, the air guide plate 5 is composed of multiple steel plates connected by connectors 6. The connectors 6 are made of pins. When the two steel plates are subjected to the tension of the rope, they can rotate around the pins to realize the extension and retraction function of the air guide plate.

[0029] Further optimize the above technical solutions, such as Figure 1 , 2 As shown in Figure 9, the column 1 has a battery inside, and a photovoltaic panel 19 for powering the battery is located on the top of the column 1. The battery 19 provides power to the anemometer 2, wind vane 3, drive device, and controller. Both the battery and controller can be integrated with the second motor. Electricity is stored in the battery through the photovoltaic panel, and clean energy is used to generate power. Simultaneously, both the first and second motors are low-speed motors. In idle state, the wind guide plate is in a retracted state; in windy or snowy weather, the wind guide plate automatically expands as needed. This results in low energy consumption and features clean, environmentally friendly, and efficient operation.

[0030] The working principle of this invention is as follows: Wind speed and direction are measured continuously in the wind field using an anemometer and wind vane. This data is transmitted to the device's controller, which processes and evaluates the data. The frontal wind speed is classified into three levels: high, medium, and low. When the wind speed is in the high-speed range, the wind deflector does not need to be opened; at this speed, the wind is sufficient to blow snow without the deflector's acceleration. When the frontal wind speed is in the low-speed range, the wind deflector remains retracted, making it difficult for snow to accumulate on the road surface. When the frontal wind speed is in the medium-speed range, the wind deflector opens under the device's operation. When the frontal wind speed is stable, the wind deflector is rotated to the corresponding angle according to a pre-set relationship between wind speed and wind deflector angle. When the frontal wind speed is unstable, the wind deflector angle remains unchanged. Specifically, when the actual wind speed exceeds a certain value, the wind deflector opens. At this time, the presence of the wind deflector reduces the impact of crosswinds on vehicles, ensuring driving safety.

[0031] The snow-blowing effect and operating principle of this invention were simulated using Ansys software. The snow-blowing effect of the guide vane at different angles under the same wind speed was analyzed using the software. The set wind speed was 10 m / s, and the angles of the guide vane were 90° (vertical) and 70° (angle between the guide vane and the horizontal plane). Under these conditions, the simulated effects are shown in the following figures. Figure 12 , Figure 13 As shown in the figure, the horizontal axis represents the erosion distance (which refers to the range of acceleration of snow particles by the wind-blown airflow at the bottom of the guide plate), and the vertical axis represents the overall height of the guide plate. In the vertical case, the ratio of the guide plate height to the erosion distance is approximately 1:2, while in the 70° case, the ratio is approximately 1:3. Comparing the figures for the two cases reveals that at the same wind speed, different angles of the guide plate have different effects on the acceleration range of the wind field. Therefore, this invention, at a certain wind speed, fully utilizes the snow-blowing capability of the guide plate by changing its angle through rotation, thereby increasing the snow-blowing range and enhancing the snow-blowing effect.

[0032] In summary, this invention has the advantages of simple and compact structure and good snow-blowing effect. The wind deflector can accelerate the incoming airflow, change the flow field morphology around the roadbed, and cause snow particles to quickly reach the roadbed surface, thereby reducing snow deposition near the road surface and lowering snow concentration. It is a relatively new snow and wind protection measure. The wind deflector in this invention can autonomously adjust its angle and extension according to wind speed and direction, which can promptly blow away snow on the road surface without snow particle deposition. The wind deflector is deployed when in use and retracted when not in use, which has a better snow-blowing effect than the fixed wind deflector in the prior art, and does not affect the driving and viewing route. At the same time, the wind deflector and the column only require a small amount of materials, without the need for a large amount of concrete and steel materials, which is simpler and more convenient than snow forests and snow walls.

[0033] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
