Description

Technical Field

[0001] This utility model belongs to the technical field of windbreak and sand-blocking devices, specifically relating to a wind turbine-type sand-blocking fence. Background Technology

[0002] Strong winds in some desert regions of Northwest China can whip up sand particles, creating sandstorms. These sandstorms not only erode surface soil but also damage vegetation. When they encounter obstacles such as railways and highways, they form sand dunes. Sand accumulation can cause road blockages, increase road maintenance costs, and in severe cases, even disrupt traffic and hinder the normal operation of transportation lines. In response to the natural conditions of wind-blown sand areas and the characteristics of railway sand hazards, breakthroughs have been achieved in the principles and measures for fixing shifting sand through continuous exploration and repeated practice. A railway sand control system has been established, characterized by "primarily stabilization combined with obstruction, primarily biological sand fixation supplemented by mechanical sand fixation."

[0003] Sand-blocking fences are important facilities for preventing and controlling wind and sand disasters. They are widely used in infrastructure construction such as railways and highways and play a significant role in desert control and sand prevention projects. Firstly, by intercepting sand particles in wind-blown sand flows, sand-blocking fences effectively reduce the threat of wind and sand to critical infrastructure such as railways and highways, thus protecting the safety and smooth flow of transportation routes. Secondly, sand-blocking fences can alter the movement pattern of wind-blown sand flows, reduce wind speed, and promote sand deposition near the fences, forming sand dikes, further stabilizing shifting sand and preventing sand dune movement. Furthermore, sand-blocking fences can be combined with sand-fixing measures, such as planting vegetation, to further consolidate the sand-fixing effect.

[0004] The strong winds of Northwest China are also a clean and renewable energy source. The ingenious combination of wind power generation and sand control measures not only allows for real-time monitoring of wind conditions but also provides precise data support for the design and implementation of sand control measures. Northwest China possesses enormous wind power potential. Through the rational development and utilization of these resources, it is possible not only to meet the rapidly growing electricity demand but also to significantly reduce dependence on fossil fuels, thereby lowering emissions of greenhouse gases such as carbon dioxide. Through technological innovation and green development, combined with effective sand control measures, the damage caused by wind and sand to the ecological environment and transportation infrastructure can be effectively mitigated, promoting the sustainable development of transportation in Northwest China.

It can also better block sand by adapting to changes in the flow of sand, and can generate wind power to effectively utilize energy. At the same time, it can monitor wind speed and direction data in real time.

[0006] Therefore, the present invention adopts the following technical solution:

[0007] A wind turbine-type sand-blocking fence includes columns located on the left and right sides, which are vertically fixed to the ground; a sand-blocking net is connected between the lower parts of the two columns, which is vertically arranged and its bottom is close to the ground; a sand-blocking impeller matrix is ​​connected between the columns above the sand-blocking net.

[0012] Furthermore, the generator fan includes a fixed base, an oscillating base, and a wind turbine; the fixed base is fixedly connected to a vertical rod inside a circular notch, and an oscillating base is rotatably connected to the top of the fixed base. The oscillating base can rotate in the vertical direction, and the wind turbine is connected to the oscillating base through a rotating shaft. When the oscillating base rotates, it drives the wind turbine to adjust its orientation; a generator is installed inside the oscillating base, and when the wind turbine rotates, it drives the generator to generate electricity.

[0013] Furthermore, an angle limiting component is provided between the fixed base and the oscillating base. The angle limiting component is used to limit the maximum oscillation angle of the oscillating base. A fan-shaped groove is opened at the bottom of the oscillating base, and a vertical limiting pin is connected to the top of the fixed base. The limiting pin passes into the fan-shaped groove. The maximum oscillation angle of the oscillating base is the central angle of the fan-shaped groove. When the oscillating base rotates to the maximum angle, the limiting pin abuts against the side wall of the fan-shaped groove to limit it.

[0014] Furthermore, a return-to-center component is provided between the fixed base and the oscillating base. The return-to-center component is used to drive the oscillating base back to center.

[0017] The beneficial effects of this utility model are as follows:

[0018] A wind turbine is installed on the windward side of the fence, transforming its static sand-blocking function into a dynamic one through turbine rotation. This design shifts the original passive protection mechanism into an active measure to reduce wind speed. During operation, when the fence faces sandstorms, the wind and sand drive the turbine to rotate. The turbine blades significantly impede sand particles during rotation, generating tip and center vortices that concentrate sand particles, reducing the amount of sand carried by the airflow and causing sand to deposit near the fence, effectively restricting their free passage. Simultaneously, the turbine converts wind energy into mechanical energy, consuming the momentum of the sand and allowing the fence to maintain stability against strong winds while having a large contact area with the sand. Furthermore, the turbine can automatically adjust its angle by rotating left or right according to wind direction, aligning the turbine's front with the sand direction to further enhance sand-blocking effectiveness. This wind turbine-type sand-blocking fence also incorporates a generator, generating electricity through turbine rotation, effectively utilizing renewable energy and reducing external energy demands. The top of the fence is also equipped with a wind speed and direction measuring instrument, which is powered by a battery and can monitor and record wind speed and direction data in real time.

[0033] Hollow pipes are installed inside the base 110, column 120, crossbar 130, and generator fan 140. The lower end of the hollow pipe in the column 120 is connected to the hollow pipe in the base 110, and the upper end of the hollow pipe in the column 120 is connected to the lighting device 160.

[0036] The working principle of the windmill-type sand-blocking fence provided in this embodiment is as follows: This utility model involves installing a windmill device on the windward side of the fence, and realizing the transformation from the static sand-blocking function of the traditional fence to a dynamic sand-blocking function through the rotation of the windmill. This design transforms the original passive protection mechanism into an active measure to reduce wind speed. During the use of the windmill-type sand-blocking fence, when the fence faces the sandstorm, the sandstorm drives the windmill to rotate. The blades of the windmill have a significant blocking effect on the sand particles during rotation. The generated tip vortices and central vortices have a gathering effect on the sand particles, reducing the amount of sand carried by the airflow, causing the sand particles to deposit near the sand-blocking fence, effectively restricting the free passage of sand particles. At the same time, the windmill converts wind energy into mechanical energy during rotation, consuming the momentum of the sandstorm, so that the fence has a large contact area with the sandstorm while resisting the impact of strong winds and maintaining stability. In addition, the windmill device can automatically adjust the angle of the windmill by rotating left and right according to the change of wind direction, so that the front of the windmill is aligned with the direction of the sandstorm, further improving the sand-blocking effect. This wind turbine-type sand-blocking fence has a built-in generator that generates electricity through the rotation of the wind turbine, effectively utilizing renewable energy and reducing external energy demand. The top of the fence is also equipped with a wind speed and direction meter, powered by the wind turbine generator, which can monitor and record wind speed and direction data in real time.

[0037] When sandstorms hit the fence at an angle, the wind turbine can rotate left and right to block the sandstorms from the front. The angle limiting component can limit the angle of rotation of the wind turbine to ensure that the edge of the wind turbine will not hit the fence and get stuck. When the sandstorms hitting the fence at an angle decrease, the centering component can gradually pull the wind turbine back to the center direction when it is tilted to one side, so as to prevent the wind turbine from being unable to turn to the other side normally when sandstorms occur in other directions.

[0038] The design was further optimized so that the total length of the column is 2.7m, the lower end is buried 1.0m underground, the upper end protrudes 1.7m above the ground, and the distance between the two columns is 3m.

[0039] Further optimization of the design is needed. Since the wind turbine device needs to be lightweight so that it can be blown by the wind, the diameter of a single wind turbine is 30cm, and the fixing components and wind turbine should be made of thin and light materials.

[0040] The design was further optimized so that the distance between two adjacent horizontal bars is 30-35cm and the distance between two adjacent vertical bars is 30-35cm.

[0041] The scheme was further optimized so that the distance between two adjacent wind speed and direction measuring instruments is 1-2 km, depending on the specific terrain conditions of the area.
