It should be pointed out that, in order to facilitate the description of the orientation relationship, "horizontal" is defined as the direction along the horizontal frame on the top of the frame 1, "longitudinal" is the direction along the vertical frame of the frame 1, and "front" and "rear" refer to the two sides of the hollow opening of the frame 1. The frame 1 is a hollow frame structure, including a vertical frame arranged longitudinally and a horizontal frame arranged transversely. The frame 1 is vertically fixed to the ground. A plurality of horizontal baffles 5 are arranged longitudinally in the hollow area of ​​the frame 1. The baffle 5 is rotatably connected to the vertical frame of the frame 1 through an adjustment shaft 6. A transmission-connected vertical sliding assembly and a vertical driving assembly are arranged on the vertical frame. The vertical sliding assembly is transmission-connected to the adjustment shaft 6. The vertical driving assembly drives the adjustment shaft 6 to rotate through the vertical sliding assembly, thereby adjusting the angle between the baffle 5 and the frame 1, so as to adjust the windward area of ​​the fence to adapt to windy weather.

[0026] Furthermore, if Figure 1 and Figure 2 As shown, a support base 2 is provided at the bottom of the frame 1 to contact the ground. The support base 2 is used to expand the contact area between the frame 1 and the ground and improve stability. Vertical fixing nails can be provided on the support base 2 to pass through the support base 2 and insert into the ground.

[0027] Furthermore, if Figure 1-Figure 3As shown, the vertical sliding assembly includes a rack 18 and a sliding strip 13, the rack 18 is vertically fixed on the sliding strip 13, the sliding strip 13 is slidably connected to the vertical frame, so that the rack 18 can slide along the vertical frame, and the end of the adjusting shaft 6 is axially connected with a transmission gear 19, which meshes with the rack 18. When the rack 18 slides with the sliding strip 13, the transmission gear 19 and the adjusting shaft 6 are driven to rotate, thereby rotating the baffle 5 to a certain angle. Further, the vertical driving assembly includes a threaded column 14 and a threaded sleeve 15, the threaded column 14 is vertically arranged and rotatably connected to the vertical frame, the threaded sleeve 15 is threadedly connected to the threaded column 14, and the sliding strip 13 is fixedly connected to the threaded column 14. When the threaded column 14 is rotated, the threaded sleeve 15 moves vertically, thereby driving the sliding strip 13 and the rack 18 to vertically displace, thereby realizing the process of driving the baffle 5.

[0028] Furthermore, a lifting slider 16 is provided to fix the threaded sleeve block 15 and the sliding strip 13, and a rotating threaded column 14 is provided on the outside of the vertical frame through a bracket. The rotating threaded column 14 is rotatably connected to the bracket, and a twisting wheel 12 is provided at the end of the threaded column 14 to facilitate manual operation by personnel. The twisting wheel 12 can be rotated according to the actual wind force to rotate the baffle 5 to a suitable angle.

[0029] Furthermore, if Figure 3 As shown, the racks 18 can be arranged in the same number at corresponding positions on the sliding strip 13 according to the number of transmission gears 19 and baffles 5 , and mesh with different transmission gears 19 accordingly.

[0030] Furthermore, when the baffle 5 is adjusted to a horizontal state, the area penetrating on both sides of the hollow region of the frame 1 is maximized, achieving a minimum windward area, thereby improving the windproof stability of the enclosure.

[0032] Furthermore, if Figure 4As shown, an annular fixed ring plate 20 is fixed in the protective cover 4. The number and position of the fixed ring plate 20 correspond to the adjustment shaft 6, and the two are coaxially arranged. The inner ring size of the fixed ring plate 20 is larger than the size of the adjustment shaft 6, so that the fixed ring plate 20 can be sleeved outside the adjustment shaft 6. The fixed ring plate 20 is evenly distributed on the circumference and is paired with plug blocks 22. The plug blocks 22 pass through the grooves in the fixed ring plate 20 and can slide radially. The two ends of the push spring 23 respectively abut the grooves and the plug blocks 22. It is used to push the plug blocks 22 to move toward the center of the fixed ring plate 20. The adjustment shaft 6 is provided with a slot 25 corresponding to the position and number of the plug blocks 22. The slot 25 matches the shape of the plug blocks 22. When the push spring 23 pushes the plug blocks 22 into the slot 25, the rotation of the adjustment shaft 6 is limited. By setting the fixed ring plate 20, the baffle 5 can be limited and maintained at a certain angle after the angle is adjusted.

[0034] Furthermore, if Figure 1 and Figure 5 As shown, the linear displacement mechanism includes a dual-axis motor 8, a friction wheel 9 and a sliding plate 28. The sliding plate 28 is slidably connected to the horizontal frame. The dual-axis motor 8 is fixed on the sliding plate 28. The friction wheel 9 is connected to the output shaft at one end of the dual-axis motor 8. The friction wheel 9 is rollingly connected to the horizontal frame. The friction wheel 9 is driven by the dual-axis motor 8 to make the sliding plate 28 move on the horizontal frame. The reciprocating linear displacement is achieved by adjusting the direction of the dual-axis motor 8. Furthermore, a friction plate 10 is fixed on the horizontal frame. The surface of the friction plate 10 is relatively rough and is used to roll with the friction wheel 9 to prevent the linear displacement mechanism from slipping and failing.

[0035] Furthermore, if Figure 1 and Figure 5As shown, the swing mechanism includes a fixed cylinder 3, a driven gear 11, an incomplete gear 17, a driving bevel gear 24, a bogie 26, a driven bevel gear 27 and a connecting pipe 29, wherein the driven gear 11 is fixedly sleeved on the connecting pipe 29, the incomplete gear 17 intermittently meshed with the driven gear 11 is rotatably mounted on the sliding plate 28, the torsion spring 21 is fixedly connected to the end of the bogie 26 and the fixed cylinder 3, the driving bevel gear 24 is driven to rotate by an output shaft of the double-axis motor 8, and the driven bevel gear 27 coaxially fixed with the incomplete gear 17 is meshed and connected to the driving bevel gear 24. Further, the external pressure water source is connected and transported to the fixed cylinder 3 through the connecting pipe 29, and then enters the dust reduction nozzle 7, and multiple groups of nozzles are arranged on the dust reduction nozzle 7. The water source is sprayed out from the nozzle of the dust reduction nozzle 7 in atomized form to perform a spray dust reduction operation, thereby realizing spray dust reduction at different positions. Furthermore, the active bevel gear 24 drives the driven bevel gear 27 and the incomplete gear 17 to rotate, and the incomplete gear 17 alternately meshes with the driven gear 11. Under the torsional force of the torsion spring 21, the bogie 26 drives the dust reduction nozzle 7 to rotate alternately clockwise and counterclockwise to achieve a swinging spraying effect, which greatly increases the area of ​​spraying dust reduction and significantly improves the dust reduction effect of civil construction.

[0036] In summary, the present invention forms a fence for the civil construction area through the multiple baffles 5 and the frame 1. The baffles 5 can be adjusted to rotate to a horizontal position through the angle adjustment assembly, so as to reduce the windward area of ​​the fence in windy weather, avoid lodging, and effectively improve the protection stability of the fence. The linear displacement mechanism can drive the swing mechanism and the dust suppression nozzle 7 to move linearly relative to the frame 1, and the swing mechanism can rotate alternately clockwise and counterclockwise, so that the water vapor sprayed by the dust suppression nozzle 7 can be diffused over a large range, greatly improving the dust reduction effect in the civil construction area.
