Description

Technical Field

[0001] The utility model belongs to the technical field of highway wind and snow prevention, and specifically relates to a highway wind and snow prevention device integrated with photovoltaic power generation. Background Art

[0002] Wind-driven snow is one of the natural disasters that often occur on northern winter highways in China. Under the influence of terrain, structures, and abnormal airflows of obstacles, snow accumulates within the limits of highways and railways or at important structures, bringing problems such as icing, snow accumulation, and blocked visibility, hindering and cutting off traffic, and even leading to traffic accidents and affecting traffic safety. In particular, highway pavements are more affected by wind-driven snow disasters. For example, low temperatures and snowfall cause the highway pavement to freeze, which easily leads to vehicle out-of-control and skidding. In addition, the icy pavement also affects braking distance and driving controllability, and in severe cases, it even leads to highway closure or traffic jams. Snow accumulation may also obscure road signs and traffic signals, reducing the driver's visual recognition ability and increasing the risk of traffic accidents.

[0003] In areas where wind-driven snow occurs frequently, the application of wind and snow prevention devices is particularly important. As a common and widely used wind and snow prevention measure, snow fences have demonstrated their effectiveness in preventing wind-driven snow. However, the traditional design of snow fences mainly focuses on a single wind and snow prevention function, which to a certain extent limits the exertion of their comprehensive utility. At the same time, there is often a large amount of unused idle land between the snow fence and the highway, which not only causes waste of land resources but also affects the overall wind and snow prevention effect and the harmony of the regional environment. Therefore, it is necessary to innovate and improve the existing snow fence technology to effectively utilize land resources while maintaining its wind and snow prevention function.

[0004] Since highways (railways) are linear infrastructure, making full use of the land along the road to develop photovoltaic power generation and form an incremental road-derived economy will help reduce carbon emissions in the transportation field. In the past, for areas prone to wind-driven snow disasters, photovoltaic panels installed in high-altitude areas with rich wind resources were often damaged due to strong winds, resulting in the failure to achieve the expected power generation benefits. Therefore, it is very important to develop wind protection technology to protect photovoltaic panels from wind disasters. Integrating photovoltaic power generation facilities with snow fences, which have both power generation and wind-driven snow prevention functions, can not only efficiently utilize the land resources along the highway to develop road-derived economy but also protect photovoltaic facilities from wind and snow. This device has the value of popularization and application. Content of the Utility Model

[0005] The purpose of the utility model is to aim at the deficiencies of the existing technology, and aims to provide a highway wind and snow prevention device integrated with photovoltaic power generation, solve the problem of easy occurrence of wind-driven snow disasters on highways, form a multi-functional snow fence with photovoltaic power generation benefits, and reduce the risk of photovoltaic panels being damaged by wind disasters.

[0006] To achieve the above object, the technical solution adopted by the present utility model is as follows:

[0007] Provide a highway snow and wind prevention device integrated with photovoltaic power generation, which is arranged on the windward side of the highway where snowdrift disasters occur frequently. It includes a concrete base, a concrete snow retaining wall, photovoltaic support columns, photovoltaic support cross-columns, photovoltaic panels, and arc-shaped wind deflectors. The photovoltaic support columns are fixedly connected to the top surface of the concrete base through a connecting device. The photovoltaic support cross-columns are fixedly connected to the columns by bolts. The photovoltaic support cross-columns are obliquely inserted into the holes reserved in the concrete snow retaining wall. The photovoltaic panels are fixedly connected to the photovoltaic support cross-columns by bolts. The arc-shaped wind deflectors are fixed to the upper end of the concrete snow retaining wall through bolt connections and insertion into the reserved pits on the snow retaining wall. The concave side of the arc-shaped wind deflector is used as the windward end.

[0008] Preferably, the connecting device includes a photovoltaic support base and a triangular connecting frame. Corresponding holes are reserved in the design of the photovoltaic support base and the triangular connecting frame, and they are firmly connected together by bolts, nuts, and washers.

[0009] Preferably, prefabricated holes are provided on both the photovoltaic support cross-columns and the columns, and bolts are installed in the prefabricated holes of the support. The support components are connected together by bolts, nuts, and washers.

[0010] Preferably, the photovoltaic support cross-columns are obliquely inserted into the holes reserved on the wall surface of the snow retaining wall.

[0011] Preferably, holes are drilled in advance at the four corners and the middle position of the photovoltaic panel, and the photovoltaic panel is fixed to the photovoltaic support cross-column using bolts, nuts, and washers.

[0012] Preferably, pits for inserting the installed arc-shaped wind deflectors are reserved at the upper end of the concrete snow retaining wall before pouring. Gasket devices are welded on both sides of the base of the arc-shaped wind deflector, facilitating the fixed connection (this embodiment is a bolt connection) between the arc-shaped wind deflector and the snow retaining wall after it is inserted into the pit.

[0013] Compared with the prior art, the beneficial effects of a highway snow and wind prevention device integrated with photovoltaic power generation provided by the present utility model are as follows: The highway snow and wind prevention device integrated with photovoltaic power generation provided by the present utility model includes a concrete base, several photovoltaic support cross-columns and columns, photovoltaic panels, a photovoltaic support base, a triangular connecting frame, a concrete snow retaining wall, and arc-shaped wind deflectors.

[0014] (1) The photovoltaic support cross-columns are obliquely inserted into the holes reserved on the wall surface of the snow retaining wall, having good stability and load-bearing capacity, ensuring that the photovoltaic is not damaged under snowy and windy weather conditions;

[0015] (2) As a concrete structure, the concrete snow retaining wall has a long service life and is not easily corroded or damaged. At the same time, the concrete snow retaining wall can prevent snow from accumulating on the road under the action of wind, keeping the road unobstructed and safe;

[0016] (3) The arc-shaped wind deflector can use its arc design to more effectively guide and disperse the snow and wind flow. When the snow and wind flow is blocked in front of the arc-shaped wind deflector, the air flow is gradually pressurized, and a strong vortex deceleration zone can be formed in the ground boundary layer, causing the snow grains to fall and deposit. Installing an arc-shaped wind deflector on the concrete snow retaining wall can further enhance the guiding effect on the snow and wind flow, making the snow and wind flow flow in a predetermined direction, blocking the snow and wind flow and the accumulated snow on the windward side, and improving the snow prevention efficiency.

[0017] (4) Integrating photovoltaic power generation into the highway snow retaining wall device can not only develop and utilize solar power generation but also prevent the invasion of wind-blown snow into the highway. At the same time, it can effectively protect the photovoltaic power generation facilities from being damaged by the wind, advocate the road-derived economy, and increase economic benefits.

[0023] The following will describe the technical solutions in the present invention in more detail in conjunction with the drawings of the present invention. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] The purpose of the present utility model is to provide a highway wind and snow protection device integrated with photovoltaic power generation, which can solve the wind and snow protection problem of highways with photovoltaic panels laid beside them, and improve the energy utilization efficiency to achieve the purpose of road-derived economy.

[0025] As Figures 1 to 3 shown: This embodiment provides a highway wind and snow protection device integrated with photovoltaic power generation. Compared with the prior art, the highway wind and snow protection device integrated with photovoltaic power generation of the present utility model is installed on the windward side of the highway in sections with frequent wind-driven snow disasters, where the photovoltaic panels face south and the snow protection direction faces the windward side. It includes photovoltaic panels 1, photovoltaic support columns 2, photovoltaic support crossbars 3, concrete bases 4, concrete snow retaining walls 5, arc-shaped wind deflectors 6, pits 7, gaskets 8, and bolt holes 9. The present utility model mainly uses the concrete snow retaining wall 5 and the arc-shaped wind deflector 6 to form a highway wind and snow protection device integrated with photovoltaic power generation, which is installed on highways with frequent wind-driven snow disasters. By reasonably utilizing land resources, the two are combined together, advocating the concept of road-derived economy.

[0026] The photovoltaic support columns 2 are fixed on the concrete base 4 with connecting devices. The photovoltaic support crossbars 3 are fixed on the photovoltaic support columns 2 by bolts. At the same time, one end of the photovoltaic support crossbar 3 is obliquely inserted into the holes reserved in the concrete snow retaining wall 6. A number of photovoltaic support crossbars 3 are fixed on the photovoltaic support crossbar 3 to fix the photovoltaic panels 1. The four corners and the middle positions of the photovoltaic panels 1 are pre-drilled, and the photovoltaic panels are fixed on the photovoltaic support crossbar 3 with bolts, nuts, and washers. After the arc-shaped wind deflector 6 is inserted into the pits 7 reserved on the concrete snow retaining wall 5 and poured, the gasket 8 is connected and fixed to the concrete snow retaining wall 5 through the bolt hole 9 with bolts.

[0027] Specifically, the concrete base 4, as a concrete base, provides a solid support and a stable installation platform for the photovoltaic system, can withstand the weight of the photovoltaic system itself and the influence of wind and snow flow loads, and improves the service life.

[0028] Specifically, the connecting device includes a photovoltaic support base, a photovoltaic support triangular connecting frame, and bolts. The photovoltaic support base, the triangular connecting frame, the photovoltaic support column 2, and the photovoltaic support crossbar 3 are all connected and fixed with the triangular connecting frame by bolts.

[0029] The photovoltaic support columns 2 and the photovoltaic support crossbars 3 are made of aluminum alloy structures, which have the characteristic of low temperature resistance. Due to the low density of aluminum, the installation is more convenient. At the same time, aluminum alloy has excellent corrosion resistance. For long-term exposure outdoors and being affected by wind and snow flow, choosing aluminum alloy can extend the service life of the photovoltaic support and reduce the maintenance cost.

[0030] The arc-shaped wind guide plate 6 is made of a low-temperature resistant steel structure, which has low sensitivity to low temperatures and can maintain good stability in a low-temperature environment. At the same time, the steel structure itself has high strength and rigidity and can resist the effects of external loads such as wind and snow.

[0031] Specifically, by measuring in advance the angle and position of the photovoltaic bracket cross column 3 at which it is obliquely inserted into the wall of the concrete snow retaining wall 5, the concrete snow retaining wall 5 is dug to allow one end of the photovoltaic bracket cross column 3 to be inserted into the reserved hole in the concrete snow retaining wall 5 at a suitable position and angle. This allows the photovoltaic bracket to have better stability and load-bearing capacity, ensuring that the photovoltaics are not damaged under severe weather conditions such as strong winds, rain and snow, while reducing the use of photovoltaic brackets and saving costs.

[0032] Specifically, the depth of the groove 7 is slightly greater than the distance from the gasket 8 to the bottom of the arc-shaped wind deflector 6. When the bottom of the arc-shaped wind deflector 6 is inserted into the groove 7 in the concrete snow retaining wall 5 and poured, the six gaskets 8 welded on the arc-shaped wind deflector 6 overlap with the bolt holes 9 on the concrete snow retaining wall 5, and the two are fixed by bolts, thereby improving the stability of the arc-shaped wind deflector 6.

[0033] The working principle and working process of the utility model are as follows: when the wind and snow flow blows, the concrete snow retaining wall 5 blocks part of the snow particles outside the concrete snow retaining wall 5, and the arc-shaped wind guide plate 6 uses its arc-shaped design to effectively guide the flow direction of the wind and snow flow. At the same time, the wind and snow flow will gradually increase the pressure to form a strong vortex deceleration zone, which is conducive to the falling and deposition of snow particles. When the wind and snow flow enters the downwind port of the arc-shaped wind guide plate 6, the arc-shaped wind guide plate 6 converts the pressure energy into kinetic energy, so that the speed of the wind and snow flow at the downwind port increases. This acceleration effect helps to take away the snow particles deposited in the vortex deceleration zone, prevents the snow particles from accumulating in large quantities on the back side of the concrete snow retaining wall 5, and protects the concrete snow retaining wall 5 and the surrounding environment.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
