[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or position relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0027] Please refer to Figure 1-2 As shown, the present invention is a dust removal device for building construction. The dust removal device includes a plurality of tee fittings 11 connected in series through a water pipe 10. The two ends of the main pipe of the tee fitting 11 are respectively connected to the water pipe 10, and the end of the branch pipe of the tee fitting 11 is connected to a spray head 12; and the tee fitting 11 at the head end is connected to a high-pressure water pump through the water pipe 10, and the port of the tee fitting 11 at the end is closed. Then, during use, by controlling the high-pressure water pump to supply water to the system composed of the water pipe 10 and the tee fitting 11, the water is then sprayed out through the spray head 12 to complete dust reduction.

[0028] During use, the high-pressure water pump is connected to the intelligent controller, and the intelligent controller is connected to the dust sensor. The dust sensor monitors the dust concentration in real time and triggers the water spraying action. When the dust sensor detects that the PM2.5 concentration exceeds the standard, it triggers the high-pressure water pump to start, and the atomizing nozzle sprays a fan-shaped water mist. During night construction, the timing module is set to spray for 2 minutes every 30 minutes to reduce manual intervention.

[0029] It can be known that, in order to carry out dust removal and prevent the dust generated in the construction area from escaping to the surrounding area, it further includes a fence 1 for enclosing the construction area. The water spraying mechanism composed of a water pipe 10, a tee fitting 11, etc. is installed on the top of the fence 1.

[0030] Specifically, a fixing part A2 is fitted and installed on the top of the fence 1. The fixing part A2 is used to fix the tee fitting 11 on the top of the fence 1. For example Figure 3-4 , the fixing part A2 includes two side plates A21. A pair of connecting rods A20 are connected between the tops of the two side plates A21. A clamping plate 23 is arranged on one side of the connecting rod A20, and an arc-shaped notch 231 for cooperating with the main pipe is arranged at the end of the clamping plate 23. During installation, the inner walls of the two side plates A21 respectively abut against the inner and outer side walls of the fence 1. A locking bolt A21 abutting against the fence 1 is arranged on the side plate A21, and at this time, the branch pipe of the tee fitting 11 passes through the gap between the pair of connecting rods A20.

[0031] Based on the above, in order to facilitate the adjustment of the orientation of the nozzle 12 provided on the tee fitting 11, the present invention further connects a pair of connecting rods B24 between the tops of the two side plates A21. The connecting rod B24 is located directly above the connecting rod A20 and is arranged with a gap. It further includes a stop rod 25 arranged between the connecting rod B24 and the connecting rod A20, and an adjusting bolt 212 whose threaded connection end at the top of the side plate A21 abuts against one side of the stop rod 25. That is, during use, by controlling the rotation of the adjusting bolt 212 to drive the stop rod 25 to move along the direction perpendicular to its length, and controlling the two stop rods 25 to respectively abut against the outer side walls of the branch pipes of the tee fitting 11, thereby adjusting the orientation of the branch pipes of the tee fitting 11.

[0032] Specifically, the stop rod 25 includes a stop rod body 251. The two ends of the stop rod body 251 are connected with protruding parts 252 protruding from the gaps between the connecting rod B24 and the connecting rod A20, and limiting parts 253 abutting against the outer walls of the connecting rod B24 and the connecting rod A20 are arranged at the ends of the protruding parts 252.

[0033] It can be known that, in order to facilitate the control of the fixing and installation depth of the fixing part A2 during use, a protruding part 22 abutting against the top surface of the fence 1 is arranged on the inner wall of the side plate A21.

[0034] During use, since the rubber hoses are selected for connecting two adjacent water pipes 10, they are likely to droop under the action of their own gravity. The present invention also provides a fixing member B3 for hooking the water pipe 10 at the top of the enclosure 1; as Figure 5-6 , the fixing member B3 includes a horizontal plate 30, and two vertical plates A32 are arranged on one side of the horizontal plate 30; a vertical plate B33 is arranged at one end of the horizontal plate 30, a bent plate 34 is arranged at the bottom end of the vertical plate B33, and reinforcing ribs 35 are arranged on the outer wall of the bent plate 34; during installation, the inner walls of the two vertical plates A32 respectively abut against the inner and outer side walls of the enclosure 1, and the water pipe 10 passes through the space formed by the vertical plate B33, the bent plate 34 and the enclosure 1; an elastic gasket is arranged inside the bent plate 34, the cross section of the elastic gasket is wavy and is in close fit with the outer wall of the water pipe 10, reducing the wear of the water pipe 10 components and preventing the water pipe 10 from falling off.

[0035] Specifically, the water outlet end of the spray head 12 is provided with a rotatable and adjustable atomizing nozzle, the atomizing nozzle is connected to the end of the spray head by threads, and anti-slip threads are arranged on the outer wall; a spiral guide vane is arranged inside the atomizing nozzle, and the spiral angle of the guide vane is 15°-30°, which is used to prevent water flow blockage.

[0036] Specifically, the enclosure 1 is composed of several enclosure units, and two adjacent enclosure units are fixedly connected by plug-in connectors; the plug-in connectors include U-shaped card slots clamped with the side walls of the enclosure 1, and locking bolts B are arranged at the open ends of the U-shaped card slots; both ends of the U-shaped card slots are respectively fixed at the tops of the two enclosure units.
