Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5 The utility model provides a technical solution: a dust removal device for engineering construction, comprising a water tank 1, a liquid inlet hole 11 being provided at the upper end of the water tank 1, a liquid storage tube 2 being rotatably mounted on the upper side of the water tank 1, extension tubes 21 being plugged and mounted on both sides of the inner cavity of the liquid storage tube 2, a first liquid spray hole 23 and a second liquid spray hole 24 being respectively provided at the upper ends of the liquid storage tube 2 and the extension tube 21, a threaded sleeve 26 being fixedly mounted inside the two extension tubes 21, a first threaded rod 27 being rotatably mounted inside the liquid storage tube 2 and being threadedly connected to the threaded sleeves 26 on both sides, an insertion cavity 272 being provided in the first threaded rod 27, a rotating plate 28 being rotatably mounted on the outer ends of the two extension tubes 21, an insertion rod 281 plugged in the insertion cavity 272 being fixedly mounted on the opposite end surfaces of the two rotating plates 28.

[0026] Working principle: When it is necessary to adjust the water spraying range according to the road width, the rotating plate 28 can be rotated at the outer end of the extension tube 21, and the first threaded rod 27 can be driven to rotate with it through the plug-in connection between the insertion rod 281 and the insertion cavity 272. Then, through the plug-in connection between the liquid storage tube 2 and the extension tube 21, the rotating first threaded rod 27 can drive the extension tubes 21 on both sides of the liquid storage tube 2 to contract or expand through the threaded connection between it and the threaded sleeve 26, and cooperate with the first spray hole 23 and the second spray hole 24 to adjust the water spraying range.

[0027] As a further description of the above technical solution: a limited rotation seat 25 is fixedly installed on the upper side of the middle part of the inner cavity of the liquid storage tube 2, and a limited rotation block 271 rotatably connected to the limited rotation seat 25 is fixedly installed in the middle part of the first threaded rod 27.

[0028] Specifically, through the rotational connection between the limiting rotation block 271 and the limiting rotation seat 25 , the movement direction of the first threaded rod 27 can be limited in the liquid storage tube 2 to prevent the first threaded rod 27 from deflecting.

[0029] As a further description of the above technical solution: a concave cavity 3 is opened on the outer side of the upper end of the water tank 1, a liquid guide cavity 34 is fixedly installed in the water tank 1, and the liquid guide cavity 34 is arranged on the periphery of the concave cavity 3. A water pump 35 is fixedly installed in the water tank 1, and a liquid guide tube 36 is fixedly installed between the outer end of the water pump 35 and the liquid guide cavity 34. A movable sleeve 37 is rotatably installed in the concave cavity 3, and a liquid guide hole 33 is opened in the concave cavity 3 to communicate with the liquid guide cavity 34, and the inner cavity of the movable sleeve 37 is communicated with the liquid guide hole 33.

[0030] Specifically, a concave cavity 3 is provided, and the liquid storage tube 2 can be rotated by the rotational connection between the movable sleeve 37 and the liquid guide hole 33. Since the liquid guide hole 33 is interconnected with the movable sleeve 37 and the liquid guide cavity 34, the liquid inside the water tank 1 can be guided to the inner cavity of the rotating sleeve 4 through the water pump 35 in conjunction with the liquid guide tube 36;

[0031] The sliding connection between the second limiting slider 43 and the second limiting groove 42 enables the rotating threaded ring 44 to drive the movable tube 41 to move within the rotating sleeve 4 through the threaded connection between the rotating threaded ring 44 and the movable tube 41, thereby achieving the effect of adjusting the unfolded height of the liquid storage tube 2. Since the inner cavities of the rotating sleeve 4 and the movable tube 41 are interconnected, the water inside the rotating sleeve 4 can be guided into the liquid storage tube 2.
