The linkage assembly 42 is arranged above the baffle assembly 41 and is rotatably connected to the baffle assembly 41.

[0025] The above scheme is adopted: by providing a wind shelter 4, the wind shelter 4 can be opened when the wind is strong to reduce the wind resistance of the enclosure and avoid the enclosure being blown away due to excessive wind resistance.

[0026] refer to Figure 1 , Figure 2 and Figure 3 The baffle assembly 41 includes a rotating shaft 411 and a rotating plate 412. The rotating shaft 411 is arranged in the rotating groove 3, and the upper and lower ends are respectively fixedly connected to the upper surface and the lower surface of the inner part of the rotating groove 3. The rotating plate 412 is sleeved on the surface of the rotating shaft 411 and fixedly connected to the rotating shaft 411. The top end of the rotating shaft 411 passes through the rotating groove 3.

[0027] The above solution is adopted: by setting the baffle assembly 41, the baffle can rotate inwardly, and the wind can pass through the rotating groove 3 by changing the rotation angle, thereby reducing the wind resistance of the entire device.

[0028] refer to Figure 1 , Figure 2 and Figure 3 The linkage assembly 42 includes a toggle block 421 and a connecting hole 422. The toggle block 421 is arranged above the main body 1, and the lower end is fixedly connected to one end of the rotating shaft 411 extending out of the rotating groove 3. The connecting hole 422 is opened at the front end of the upper surface of the toggle block 421 and penetrates the toggle block 421.

[0029] The above solution is adopted: the linkage assembly 42 is provided to drive the baffle assembly 41 in the rotating groove 3 to rotate.

[0030] refer to Figure 3 A linkage rod 5 is arranged above the linkage component 42, and a plurality of rotating shafts 6 are arranged below the linkage rod 5. The upper end of the rotating shaft 6 is rotatably connected to the lower surface of the linkage rod 5, and the lower end is arranged in the connecting hole 422 and rotatably connected to the connecting hole 422.

[0031] The above solution is adopted: by setting the linkage rod 5 and the rotating shaft 6, the simultaneous linkage of several baffle assemblies 41 is controlled.

[0032] refer to Figure 2 A placement groove 7 is opened on the right side of the lower end of the front surface of the main body 1, and a crank 8 is arranged in the placement groove 7. The upper end of the crank 8 extends from the top of the placement groove 7 to the first rotating groove 3 on the right side of the front surface of the main body 1, and is fixedly connected to the rotating shaft 411.

[0033] The above scheme is adopted: a placement groove 7 is provided for storing the crank 8, and the crank 8 is connected to the rotating shaft 411, so as to drive the rotating shaft 411 in the first rotating groove 3 on the right side of the front surface of the main body 1 to rotate by rotating the crank 8.

[0034] refer to Figure 2 and Figure 4 The right end of the upper surface of the main body 1 is fixedly connected to a limit plate 9, and the front surface of the limit plate 9 is fixedly connected to a magnetic block 10.

[0035] The above scheme is adopted: by setting the limit plate 9 and the magnetic block 10 on its surface, it is used to limit the rotation angle of the rotating plate 412, and when the rotating plate 412 rotates to contact with the limit plate, the magnetic block 10 adsorbs and fixes it.

[0036] The working principle of this utility model:

[0037] When the wind is strong and needs to be adjusted, the crank handle 8 is set in the placement slot 7, and the crank handle 8 drives the rotating shaft 411 fixedly connected to it to rotate, and the rotation of the rotating shaft 411 drives the rotating plate 412 to rotate. At the same time, the rotating rod drives the toggle block 421 fixedly connected to it to rotate, and the rotation of the toggle block 421 pulls the rotating shaft 6 set in the connecting hole 422 to move the linkage rod 5, thereby linking several wind shelters 4 to rotate them, and when the toggle block 421 rotates to contact the limit block, the magnetic block 10 adsorbs and fixes it.

[0038] To sum up: the protective fence for road and bridge construction, through the arrangement of the main body 1, the support frame 2, the rotating groove 3, the wind shelter 4, the baffle assembly 41, the rotating shaft 411, the rotating plate 412, the linkage assembly 42, the toggle block 421, the connecting hole 422, the linkage rod 5, the rotating shaft 6, the placement groove 7, the crank handle 8, the limit plate 9 and the magnetic block 10, solves the problem that when the wind is strong, the existing fence has a large area and has a great resistance to wind. In this way, the fence will be blown down when the wind is strong, thereby affecting the fence effect and limiting the work of the fence.
