[0002] For mining sites, thermal power plants, ports and other places, in order to facilitate the storage and transportation of materials, bulk materials (such as mine powder, scattered coal, etc.) are often stacked on open air. However, due to the small particles of mine powder, scattered coal and other materials, they are easily affected by the wind in windy weather and are prone to dust raising.

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] Please refer to the following: Figures 1 to 9The structure and working principle of a windproof fence provided by an embodiment of the present invention will be described below.

[0020] Please see Figure 1 , Figure 3 and Figure 4 The windproof fence provided in this embodiment of the invention includes a fence frame 10 and a plurality of fence panel assemblies 20 spaced apart from top to bottom on the fence frame 10. The fence panel assembly 20 includes a grid plate 21 and a hole adjustment mechanism. The grating plate 21 is a flat plate extending horizontally. Ventilation holes 211 are provided along the length of the grating plate 21, extending through the thickness direction of the grating plate 21. The aperture adjustment mechanism includes two comb plates 22 located on one side of the grating plate 21, and a spacing adjustment unit. The two comb plates 22 are positioned opposite each other on both sides of the ventilation holes 211. The comb plates 22 extend along the length of the grating plate 21. Comb-like teeth are formed on the adjacent sides of the two comb plates 22, and the comb-like teeth of the two comb plates 22 are staggered along their length direction. The spacing adjustment unit is used to drive the two comb plates 22 closer to or further apart from each other. The comb plates 22 have a covered position and an open position. When in the covered position, the comb plates 22 at least partially cover the ventilation holes 211. When in the open position, the comb plates 22 and the ventilation holes 211 are staggered along the thickness direction of the grating plate 21.

[0021] Compared with the prior art, the beneficial effects of the windproof fence provided by the embodiments of the present invention are: An embodiment of the present invention provides a windproof fence including a fence frame 10 and multiple fence panel assemblies 20, which can form an isolation and windproof barrier. Each fence panel assembly 20 consists of a grid plate 21, comb plates 22, and a spacing adjustment unit. The grid plate 21 has elongated ventilation holes 211. Two comb plates 22 are staggered on one side of the grid plate 21. The spacing adjustment unit can drive the two comb plates 22 to move closer or further apart, changing the area of ​​the comb plates 22 blocking the ventilation holes 211, thereby adjusting the permeability of the windproof fence to adapt to different wind speeds and wind directions.

[0022] The fence frame 10 is formed by welding steel pipes and structural steel sections, and is used to support the fence panel assembly 20. Since the fence frame 10 will bear a significant load during use, its sturdiness must be ensured. During installation, the fence frame 10 can be buried in the ground or on a concrete platform; this installation method is suitable for immovable windproof fences. When applied to movable windproof fences, a mounting flange plate with bolt holes can be installed at the bottom of the fence frame 10 for inserting fixing bolts. Alternatively, a water tank, stones, or other counterweights can be installed at the bottom of the fence frame 10 to ensure sufficient stability to resist wind forces.

[0023] In practical use, multiple windbreaks are usually installed, enclosing the area outside the site to prevent wind and dust from affecting the bulk material piles. The height of the windbreaks is determined based on the size of the site and the stacking height of the bulk materials.

[0024] The grating plate 21 can be made of stamped metal plate. The shape of the grating plate 21 is rectangular or approximately rectangular. The grating plate 21 has ventilation holes 211, which are long strips (waist-shaped or rectangular). The ventilation holes 211 can be obtained by laser cutting directly on the steel plate or by stamping.

[0025] A porosity adjustment mechanism is located on one side of the grid plate 21 and is used to adjust the porosity of the fence panel assembly 20. The porosity adjustment mechanism includes two comb plates 22 and a spacing adjustment unit. The comb plates 22 are also metal plates, and each comb plate has multiple comb-shaped teeth arranged at equal intervals. The comb-shaped teeth of the two comb plates 22 can be adjusted as follows: Figure 3 As shown, the two comb plates 22 are arranged in a cross configuration. The spacing adjustment unit is used to drive the two comb plates 22 to move closer or further apart from each other, thereby changing the coverage area of ​​the comb teeth on the ventilation holes 211, and thus changing the permeability.

[0026] Depending on the relative positions of the comb plate 22 and the grid plate 21, the comb plate 22 has a covered position and an open position. Specifically, as shown... Figure 4 As shown, when the two comb plates 22 are in the open position, the comb plates 22 are completely hidden on the side of the grid plate 21 and will not block the ventilation holes 211. At this time, the permeability is the largest, and the airflow can pass through the windproof fence more easily, which can improve the air circulation effect of the site.

[0027] like Figure 3 As shown, when the two comb plates 22 intersect each other, they will block the ventilation holes 211 to a certain extent, reducing the permeability. When the two comb plates 22 completely intersect each other, the comb-like teeth on the two comb plates 22 overlap and can completely cover the ventilation holes 211. At this time, the fence panel assembly 20 can be equivalent to a solid panel.

[0028] The spacing adjustment unit, as a driving component, can be a telescopic cylinder or an electric telescopic rod, or a bidirectional lead screw. The bidirectional lead screw and the grid plate 21 are rotatably engaged. The bidirectional lead screw is driven to rotate by a motor. The two comb plates 22 are threadedly engaged with the two threaded parts of the bidirectional lead screw. By controlling the forward or reverse rotation of the bidirectional lead screw, the two comb plates 22 can be moved closer or further apart from each other.

[0029] Please see Figure 3 and Figure 4In some possible embodiments, the grid plate 21 is provided with a plurality of ventilation holes 211 spaced apart along its width direction, and a plurality of pore adjustment mechanisms are provided corresponding to the ventilation holes 211. Each pore adjustment mechanism can work independently without affecting each other, and different pore adjustment mechanisms can be controlled to different permeability as needed.

[0030] Please see Figure 3 and Figure 4 To maximize the ventilation holes 211 and ensure that the area between two adjacent ventilation holes 211 can conceal the comb plate 22, in some possible embodiments, the distance between two adjacent ventilation holes 211 is greater than or equal to the width of one comb plate 22, and less than the width of two comb plates 22. To avoid interference between the comb plates 22 of two adjacent aperture adjustment units when they move, the two adjacent aperture adjustment mechanisms are located on opposite sides of the grid plate 21. This arrangement ensures that the ventilation holes 211 can be opened to a large extent, while also ensuring that the area between two ventilation holes 211 allows the comb plate 22 to be completely concealed on one side of the grid plate 21, resulting in a large adjustable range for the permeability.

[0031] Please see Figure 3 and Figure 4 In some possible embodiments, the grille plate 21 has two first sliding grooves 212 along its width direction, and the two first sliding grooves 212 are arranged opposite to each other. The comb plate 22 is accommodated within the space enclosed by the two first sliding grooves 212, and the comb plate 22 slides in cooperation with the first sliding grooves 212, which helps to achieve smooth movement. When the comb plate 22 is driven to move by a lead screw, the lead screw can be set in the first sliding groove 212.

[0032] Please see Figure 1 , Figure 2 , Figures 5 to 9 In some possible embodiments, the fence frame 10 includes two posts 11 spaced apart horizontally, a fence panel assembly 20 disposed between the two posts 11, and a grid panel 21 connected to the posts 11. The posts 11 can be made of square steel, I-beams, etc. When multiple windproof fences are installed, mounting holes 111 are provided on the posts 11 for easy connection. The mounting holes 111 are used to pass bolts through, and the two posts 11 can be connected as one unit by bolts. The bolts achieve a detachable connection, making installation and disassembly convenient.

[0033] Please see Figure 2 and Figure 6In some possible embodiments, the fence frame 10 also includes a plurality of mounting blocks 12, which are spaced apart from top to bottom on the posts 11. The grid plate 21 has a pivot 213 that rotates in conjunction with the corresponding mounting block 12. The windproof fence also includes a plurality of angle adjustment components 30, which are correspondingly arranged on the mounting blocks 12 and are used to drive the corresponding grid plate 21 to rotate around its own pivot 213.

[0034] In this embodiment, the grille plate 21 has rotating shafts 213 at both ends along its length. The rotating shafts 213 are used to rotate with the mounting block 12. The tilt angle of the fence plate assembly 20 is adjusted by the angle adjustment unit, so that the fence plate assembly 20 can form a shape like... Figure 5 and Figure 7 The guide plate configuration shown in the figure indicates that the airflow path is as indicated by the arrow in the figure. The inclined guardrail assembly 20 can guide the horizontal airflow to flow obliquely upward, preventing the airflow from blowing directly onto the material and causing dust.

[0035] The angle adjustment component 30 can be driven by a motor. The output shaft of the motor drives the rotating shaft 213 of the grid plate 21 to rotate to an appropriate angle, such as 30°, 40°, 55°, etc., through gear transmission, chain transmission, etc.

[0036] Please see Figure 2 and Figure 6 In some possible embodiments, the posts 11 are provided with multiple tracks 13 at equal intervals from top to bottom. The tracks 13 extend horizontally and can be directly welded to the posts 11 or fixed by fasteners. The mounting blocks 12 slide with the corresponding tracks 13. The windbreak fence also includes multiple lateral movement components 40, which are correspondingly provided on the tracks 13 to drive the corresponding mounting blocks 12 to move along the tracks 13.

[0037] In this embodiment, the uprights 11 are also provided with horizontally extending tracks 13, the extension direction of which is perpendicular to the vertical plane where the two uprights 11 are located. The mounting block 12 can reciprocate along the horizontal tracks 13, thereby enabling the windproof fence to achieve the following... Figure 8 and Figure 9 The folded configuration is shown. In the folded configuration, the front and rear positions and tilt angles of adjacent fence panel components are different. Under certain wind speeds, the folded configuration of the windproof fence has a better windproof effect.

[0038] The transverse moving component 40 is used to drive the mounting block 12 to move along the corresponding track 13. Specifically, the transverse moving component 40 can be a drive component such as an electric telescopic plate or a telescopic cylinder.

[0039] In some possible embodiments, the windproof fence also includes a power supply component, which includes photovoltaic panels and a battery. The battery stores the electrical energy generated by the photovoltaic panels. The battery can be a common type of battery, such as a lead-acid battery or a lithium battery. The battery is electrically connected to the spacing adjustment unit, the angle adjustment component 30, and the lateral movement component 40, respectively, to provide them with power. The photovoltaic panels can convert solar energy into electrical energy, which is used to power various electrical devices and sensors. The photovoltaic panels can be directly installed on the fence frame 10, or the grid panel 21 can be made from photovoltaic panels.

[0040] In some possible embodiments, there are multiple fence frames 10, which are sequentially connected and arranged to surround the perimeter of the site. The multiple fence frames 10 enclose a circular, square or other shaped area for storing materials. Each fence frame 10 is provided with a fence panel assembly 20.

[0041] To enable real-time monitoring of wind speed and direction at the site, an anemometer and wind vane can be installed on the fence frame 10. The permeability and shape of the windproof fence can be dynamically adjusted according to wind speed, wind direction, and the site's ventilation and windproof requirements to achieve better windproof and dust suppression effects.

[0042] The windproof fence provided by this invention is suitable for sites such as mines, thermal power plants, and coal yards where bulk materials need to be stored, and has the following characteristics: Figure 1 , Figure 5 and Figure 8 The three forms shown can flexibly change their permeability and shape when facing different weather, wind speed and wind direction, so as to achieve adaptive adjustment and ensure the windproof and dust suppression effect of the windproof fence.
