[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0035] Refer to Figures 1 to 4 As shown, this embodiment provides a construction site spraying and dust reduction system, including a plurality of spraying piles 1 arranged at intervals in the construction site dust reduction area. The spraying pile 1 includes a base 11, a telescopic pile 12, a mounting seat 13, a first mounting pipe 14, and a second mounting pipe 15. The base 11 is fixedly arranged on the ground, and a concrete foundation needs to be set and fixed to the ground by anchor bolts. The telescopic pile 12 is arranged on the base 11, and the mounting seat 13 is arranged at the telescopic end of the telescopic pile 12. Furthermore, the base 11 can move up and down as the telescopic pile 12 expands and contracts, and thus the height of the spraying can be controlled.

[0036] Such as Figure 1As shown, the first installation pipe 14 is horizontally arranged on the installation base 13, and a number of first atomizing nozzles 16 are arranged at intervals on the first installation pipe 14; water mist is sprayed through the number of first atomizing nozzles 16 to spray and dust the area below the position where the first water pipe is located. Usually, both ends of the first installation pipe 14 are respectively oriented towards the adjacent spraying piles 1, facilitating the formation of a continuous mist wall. The number of spraying piles 1 are arranged in sequence to form a ring connected end to end, or are arranged in the area of the construction site where dust reduction is required according to actual needs.

[0037] As Figure 1 and 2 shown, second installation pipes 15 are vertically arranged at both ends of the first installation pipe 14. The first installation pipe 14 is communicated with the second installation pipes 15. A number of second atomizing nozzles 17 are arranged on the second installation pipes 15, and the second atomizing nozzles 17 on the two second installation pipes 15 are arranged back to back; the second installation pipes 15 are vertically and communicatively arranged on the first installation pipe 14, making the overall structure relatively compact and not stretching to occupy too much space. At the same time, the number of second atomizing nozzles 17 on the two second installation pipes 15 spray mist to the left and right sides, and the water mist sprayed by the second atomizing nozzles 17 covers a larger range through the height difference.

[0038] More specifically, as Figure 1 and 2 shown, it further includes a blowing member 18. Two blowing members 18 are symmetrically arranged on the first installation pipe 14, and the two blowing members 18 respectively blow air towards the two second installation pipes 15. Further, the water mist ejected from the number of second atomizing nozzles 17 is blown to both sides, so that the sprayed water mist covers a larger range. Furthermore, the installation of pile positions can be reduced, materials can be saved, and the occupied space is also small, but the spraying dust reduction range and effect can both meet actual needs.

[0039] More specifically, as Figure 1 and 2 shown, a number of groups of the first installation pipe 14 and the second installation pipes 15 are provided, and the number of second installation pipes 15 are arranged at intervals on the installation base 13. During specific implementation, the atomization amount of a single pile position can have a large spraying range not only in the left and right directions, but also in the front and back directions. Furthermore, the corresponding number of first installation pipes 14 can be enabled according to actual needs to form a mist wall with the required thickness to meet the need for a large amount of atomized dust removal.

[0040] During specific implementation, the blowing member 18 is a fan, and the fan can be directly electrically controlled to adjust the wind force of the fan so that the water mist ejected from the number of atomizing nozzles on the second installation pipe 15 drifts to an appropriate distance.

[0041] As another embodiment, the air blower 18 is an air amplifier, and further includes an air compressor 3, a high-pressure pipe 31, and a plurality of pressure-dividing pipes 32. The output end of the air compressor 3 is connected with a high-pressure pipe 31, and the high-pressure pipe 31 is connected with a plurality of pressure-dividing pipes 32. One pressure-dividing pipe 32 is connected with one air amplifier. During specific implementation, a small amount of compressed air is pumped to a plurality of air amplifiers by the air compressor 3 as a power source, and the air amplifier can output a relatively large amount of gas to blow the mist of a plurality of second atomizing nozzles 17 to disperse to both sides, with less energy consumption and good effect; the working principle of the air amplifier is based on the Coanda effect in fluid mechanics. When compressed air is ejected through a narrow annular gap, it will form a low-pressure area around the gap, and this low-pressure area attracts the surrounding air to enter, and after mixing with the original compressed air, it is blown out from the other side of the amplifier together. In this way, the air flow can be amplified to 25 times or more of the input air flow.

[0042] As Figure 1 , 3 As shown in FIGS. 3 and 4, the telescopic pile 12 includes a pile pipe 121, a telescopic pipe 122, a screw rod 123, and a driving device. The pile pipe 121 is vertically arranged on the base 11. The lower end of the telescopic pipe 122 is slidably arranged in the pile pipe 121. The upper end of the telescopic pipe 122 is connected with the mounting seat 13, and the telescopic pipe 122 is in spline connection with the pile pipe 121;

[0043] The screw rod 123 is coaxially arranged in the pile pipe 121. The screw rod 123 is rotatably arranged in the pile pipe 121. The upper end of the screw rod 123 extends into the telescopic pipe 122 and is in threaded cooperation with the telescopic pipe 122; the driving device is used to drive the screw rod 123 to rotate forward or backward.

[0044] The driving device includes a turbine 124, a worm 125, and a driving member 126. The turbine 124 is sleeved on the screw rod 123. The worm 125 is rotatably arranged on the pile pipe 121. The worm 125 is meshed with the turbine 124; one end of the worm 125 extends out of the pile pipe 121 and is connected with the driving member 126.

[0045] As Figure 1 , 3 As shown in FIGS. 3 and 4, during specific implementation, the driving member 126 is a speed reducer and can be electrically controlled. As another embodiment, the driving member 126 is a handwheel, and then manual driving control is required. The worm 125 is driven to rotate by the speed reducer or the handwheel. The worm 125 drives the turbine 124 to rotate, and the turbine 124 synchronously drives the screw rod 123 to rotate. During the forward or reverse rotation of the screw rod 123, the telescopic pipe 122 is driven to move in the pile pipe 121, so as to realize the telescoping of the telescopic pipe 122. The telescopic pipe 122 drives the mounting seat 13 to move up and down, so as to control the heights of a plurality of first atomizing nozzles 16 and second atomizing nozzles 17 to meet the on-site dust removal requirements.

[0046] More specifically, it further includes a water pump 2, a water delivery pipe 21 and a plurality of water branch pipes 22. The input end of the water pump 2 is communicated with a water pool, and the output end of the water pump 2 is communicated with the water delivery pipe 21;

The number of the used first installation pipes 14 and second installation pipes 15 is controlled by the valve 23 to meet the need of the dust removal on site for the water mist amount.

[0048] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
