[0021] A dust raising warning device for construction sites, such as Figure 1-Figure 3 As shown, it includes a base 1, a display screen 2, a cross frame 3, a connecting frame 4, an alarm light 5, a detection mechanism 6 and an exhaust mechanism 7. The display screen 2 is connected to the front side of the base 1, the rear sides of the upper and lower parts of the base 1 are connected to the cross frame 3, the connecting frame 4 is connected between the middle parts of the cross frame 3, the upper sides of the left and right parts of the base 1 are connected to the alarm lights 5, the detecting mechanism 6 is provided on the cross frame 3, and the exhaust mechanism 7 is provided on the detecting mechanism 6.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, the detection mechanism 6 includes a movable plate 61, a light measuring plate 62, a receiving plate 63, a connecting rod 64, a top column 65 and a bidirectional screw 66. The movable plate 61 is slidably connected between the left and right parts of the cross frame 3, the bidirectional screw 66 is rotatably connected to the connecting frame 4, and the bidirectional screw 66 is provided with a rotating handle. The movable plates 61 are threadedly connected to the bidirectional screw 66, the light measuring plate 62 is connected to the left movable plate 61, and the receiving plate 63 is connected to the right movable plate 61. The light measuring plate 62 and the receiving plate 63 are both electrically connected to the display screen 2, the connecting rod 64 is connected to the rear of the movable plate 61, the lower part of the connecting rod 64 is provided with a moving wheel, and the top of the connecting rod 64 is connected to the top column 65.

[0023] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the exhaust mechanism 7 includes a large folding plate 71, a fan 72, a support rod 73 and a screw 74. The support rod 73 is slidably connected between the upper sides of the top column 65, and the large folding plate 71 is arranged on the support rod 73. Three fans 72 are connected to the upper side and the rear side of the large folding plate 71. The screw 74 is threadedly connected to the large folding plate 71. The screw 74 is rotatably connected to the support rod 73, and a rotating block is arranged on the screw 74.

[0024] When the utility model is in use, the utility model needs to be placed in the operation area first, and then the bidirectional screw rod 66 is rotated. The bidirectional screw rod 66 rotates and drives the movable plate 61 to move left and right on the horizontal frame 3 through the thread, so that the distance between the light measuring plate 62 and the receiving plate 63 can be adjusted. The movable plate 61 moves and drives the top column 65 to move left and right through the connecting rod 64, and is supported by the moving wheel. After the adjustment work is completed, the light source is emitted by the light measuring plate 62, and the light source is received by the receiving plate 63, so that the penetration of the light source can be detected, and then the dust concentration in the air can be obtained, and the data is transmitted to the display screen 2. When the dust concentration in the air is too high, the alarm light 5 flashes continuously to remind people. During the detection process, the fan 72 is rotated to increase the air circulation speed, and the duration of the dust concentration increase can be detected. The screw rod 74 rotates and drives the large folding plate 71 to move and adjust through the thread. The movement of the large folding plate 71 drives the fan 72 to move, so that the air circulation angle can be adjusted as needed, which is convenient for detection.
