The fourth baffle 320 is connected with the fence frame 100 through a compression spring 330 extending horizontally, specifically, a telescopic sleeve 340 extending horizontally is arranged between the fourth baffle 320 and the fence frame 100, two sides of the fourth baffle 320 in the horizontal direction are provided with hinge shafts 321 extending horizontally, the hinge shafts 321 are rotatably mounted at one end of the telescopic sleeve 340, and the telescopic sleeve 340 limits the hinge shafts 321 of the fourth baffle 320 to move only in the horizontal direction; the compressed spring 330 is positioned in the telescopic sleeve 340 and urges the fourth baffle 320 to move away from the first baffle 210; in an initial state, the pressure spring 330 pushes the fourth baffle 320 to be at a limit position farthest away from the third baffle 310, and an included angle between a plane where the third baffle 310 and the fourth baffle 320 are located and the air inlet side of the first baffle 210 in a vertical state is an acute angle. The fourth baffle 320 extrudes the compressed spring 330 under the action of wind power, so that the included angle between the plane where the third baffle 310 and the fourth baffle 320 are located and the vertical plane is reduced, the distance between the cylindrical part and the upper end of the second baffle 220 is further increased when the first baffle 210 rotates, and the wind power for keeping the ventilation notch 110 open is further reduced after the first baffle assembly 200 rotates to open the ventilation notch 110. Through setting up second baffle subassembly 300, further increase first baffle subassembly 200 pivoted sensitivity when wind-force is great, avoid first baffle subassembly 200 to rotate when wind-force is great and influence the degree of opening of ventilation breach 110 untimely.

The temporary protection device for highway construction is used in the occasion of wind on one side, and when the temporary protection device is installed, the second baffle assembly 300 is positioned on the windward side of the first baffle assembly 200. Under the windless state, the first baffle 210 and the second baffle 220 are in the vertical state under the effect of the torsion spring, the upper end of the second baffle 220 is located at one end of the slide rail 120, and the included angle between the plane where the third baffle 310 and the fourth baffle 320 are located and the air inlet side of the first baffle 210 is an acute angle. When the wind power is greater than the first preset value, the wind power pushes the first baffle 210 and the second baffle 220 to drive the cylindrical portion to rotate, so that the torsion spring stores the force, and the second baffle 220 moves towards the wind outlet side along the slide rail 120, so that the wind is allowed to pass through the ventilation notch 110; and because its lower extreme and second baffle subassembly 300 butt, first baffle 210 pushes down at the top of second baffle subassembly 300 when rotating and moves to being close to second baffle 220 direction, and then make the distance increase of cylinder portion and second baffle 220 upper end, wind-force acts on second baffle 220 promptly and makes the arm of force increase of second baffle 220 pivoted, thereby reduce the first baffle subassembly 200 of drive and rotate to making ventilation breach 110 keep the wind-force of opening, improve the sensitivity that first baffle subassembly 200 kept opening, avoid wind-force decay or unstable time to lead to first baffle subassembly 200 to frequently rotate and reset. When the wind power is reduced to a second preset value which is not enough to overcome the elasticity of the torsion spring, the first baffle 210 and the second baffle 220 return to the vertical state under the action of the torsion spring, and the second preset value is smaller than the first preset value.
When the wind power is large, the fourth baffle 320 extrudes the pressure spring 330 under the action of the wind power, so that the included angle between the plane where the third baffle 310 and the fourth baffle 320 are located and the vertical plane is reduced, the distance between the cylindrical part and the upper end of the second baffle 220 is further increased when the first baffle 210 rotates, and the wind power for keeping the ventilation notch 110 open is further reduced after the first baffle assembly 200 rotates to open the ventilation notch 110. And the larger the wind force is, the more the fourth baffle 320 and the third baffle 310 rotate at a greater angle, and the greater the distance between the cylindrical portion and the upper end of the second baffle 220 increases when the first baffle 210 rotates, the smaller the wind force capable of keeping the ventilation gap 110 open, and the more sensitive the rotation of the first baffle assembly 200. Through setting up second baffle assembly 300, further increase the pivoted sensitivity of first baffle assembly 200 when wind-force is great, avoid first baffle assembly 200 to rotate when not in time influence the degree of opening of ventilation breach 110 when wind-force is great.
