When combined, the hollow boxes 3 on the two groups of construction fences 1 are connected by the first connecting ring 4 and the first rubber sleeve 5. After the construction fence 1 is fitted with the construction fence 1, a group of first connecting rings 4 at the outer end of the first rubber sleeve 5 is threadedly connected to the hollow boxes 3 on one group of construction fences 1, and then another group of first connecting rings 4 is threadedly connected to the hollow boxes 3 on another group of construction fences 1. The bottom pipes 27 on the two groups of construction fences 1 are connected by the second rubber sleeve 25 and the second connecting ring 26. Both the first rubber sleeve 5 and the second rubber sleeve 25 are rubber products, so they can be stretched and twisted. The hollow box 3 and the bottom pipe 27 at the end can be sealed with a matching sealing component or a cover to prevent water leakage and air leakage; First, use the vacuum mechanism to vacuum, turn on the vacuum pump 24, and under the action of the vacuum pump 24, the dust from the outside enters the interior of the construction fence 1 through the air holes 28, and the clean air flows out after being filtered by the first filter plate 32 and the second filter plate 35. Most of the dust remains on the first filter plate 32, and a small part remains on the second filter plate 35; Then, the spray mechanism is used to reduce dust. The water pump 8 is turned on. The water pump 8 transports the water in the water storage barrel 11 to the inside of the folded line pipe 7, the hollow box 3 and the connecting pipe 13 through the buried pipe 9, and sprays it out through the nozzles 15 arranged at equal intervals. The motor 16 drives the gear 17 to rotate clockwise and counterclockwise, so that the nozzle 15 swings.

When spraying dust over a large area, the shielding frame 30 shields the air hole 28 and the air pump 24 is turned off. The infrared sensor 36 is used to monitor whether there are pedestrians outside the construction fence 1. When the infrared sensor 36 detects pedestrians, the infrared sensor 36 transmits information to the control panel 37. The control panel 37 controls the motor 16. The motor 16 drives the gear 17 to rotate counterclockwise, so that the gear ring 18 meshing with the gear 17 rotates clockwise, and the connecting pipe 13 fixedly connected to the gear ring 18 rotates counterclockwise, and the nozzle 15 on the connecting pipe 13 is rotated to the inside of the construction fence 1, so as to prevent the water mist sprayed from the nozzle 15 from spraying on the pedestrians; When the nozzle 15 is turned to the inner side of the construction fence 1, there is still a lot of dust on the outer side of the construction fence 1. The electric telescopic rod 29 on the left side of the construction fence 1 is started. Under the action of the electric telescopic rod 29, the shielding frame 30 moves upward, the shielding of the left shielding frame 30 is removed, and the vacuum pump 24 is started to absorb the dust on the outer side of the construction fence 1. The water storage barrel 11 is buried underground, and construction wastewater flows into the water storage barrel 11. After being filtered by the filter assembly 12, clean wastewater remains at the bottom of the water storage barrel 11. On rainy days, rainwater passes through the filter assembly 12 and enters the water storage barrel 11. The filter assembly 12 is detachably installed in the water storage barrel 11, and the filter assembly 12 can be replaced regularly. The buried pipe 9 and the external pipe 10 are both equipped with control valves, and the bottom end of the buried pipe 9 is fixedly connected to the bottom end of the water storage barrel 11. When the water in the water storage barrel 11 is used up, the control valve inside the buried pipe 9 is closed, and the control valve inside the external pipe 10 is opened. The external pipe 10 is connected to the water source to use the external water source; The shielding frame 30 is symmetrically arranged about the center line of the construction fence 1. When dust collection is not required, the shielding frame 30 can be used to block dust, thereby preventing dust from leaking out. Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the above embodiment 1. The existing environmental protection dust removal equipment for environmental protection construction projects removes dust by means of a spray mechanism and a dust suction mechanism structure. However, dust suction after spraying will cause the inhalation of air with water. Water and dust will stick to the filter structure, affecting the filtration of the filter structure, thereby affecting the dust suction effect. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 1-Figure 5 , Figure 7-10 and Fig.13 As shown; A linkage mechanism is provided below the spray mechanism, and the linkage mechanism includes a motor 16, a gear 17, a gear ring 18, a pulley 19, a transmission belt 20 and a screw 21.

The diameter of the gear 17 is smaller than the diameter of the gear ring 18. When the gear 17 rotates one circle, the gear ring 18 does not rotate half a circle. When the screw 21 rotates to drive the moving rod 22 to move from the front end of the first filter plate 32 to the collection bucket 33, it will not affect the rotation of the gear ring 18 and the nozzle 15. The processing cover 34 is fixedly connected to the construction fence 1 by screws. When the dust inside the collection bucket 33 needs to be processed, the screws used to connect the processing cover 34 and the construction fence 1 are removed, and then the processing cover 34 is removed, and then the collection bucket 33 is rotated to remove the collection bucket 33; The above completes a series of operations of the environmental protection dust removal equipment for environmental protection construction projects.
