Description

Technical Field

[0001] The present invention relates to the technical field of construction dust reduction, and in particular to a dust reduction device for environmental protection engineering construction. Background Art

[0002] During environmental protection project construction, such as road construction, building demolition, mining, or earthwork transportation, large amounts of suspended particulate matter (PM10, PM2.5, etc.) are easily generated on-site due to factors such as mechanical operation, material handling, and natural wind forces, resulting in severe dust pollution. Traditional dust suppression devices (such as high-pressure sprayers, sprinkler trucks, or fixed sprinkler systems) often utilize rigidly mounted spray structures. Their nozzles are typically welded or bolted to brackets, columns, or pipelines, requiring only adjustment of the entire device's position or rotation of the base to change the spray direction.

[0003] For example, the patent document with publication number CN219848739U in the prior art provides a dust reduction device for environmental protection engineering construction; the device is provided with a threaded screw and multiple first spray heads. When performing dust reduction work, it only needs to drive the threaded screw through the first motor, and then drive the first spray head on the slider through the threaded screw, so that it can spray dust back and forth more evenly, thereby improving the work quality.

[0004] However, the device still has the following problems: (1) There are blind spots in spraying: In complex construction environments, such as deep foundation pits, high slopes, tunnel interiors, or special-shaped working surfaces such as building facades, fixed spray heads are limited in angle and cannot cover key areas where dust accumulates (such as high-altitude dust or low-lying dust accumulation points), resulting in poor dust reduction effects. To compensate for this shortcoming, construction units often need to add multiple spray devices, which not only increases equipment procurement and maintenance costs, but may also cause confusion in on-site pipeline layout, affecting construction efficiency; (2) Serious waste of resources: Since the spray direction cannot be accurately adjusted, a large amount of water mist may be sprayed into dust-free areas (such as equipment surfaces, construction channels, or sites where work has been completed), which not only reduces water resource utilization, but may also cause muddy and slippery construction sites, affecting machine operation and personnel safety. In addition, excessive spraying may also accelerate the corrosion of metal components, shorten the service life of equipment, and further increase project costs. Summary of the Invention

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figures 1-8A dust suppression device for environmental protection engineering construction includes a spraying vehicle 1, a water pump 13 and two sliders 11. The two sliders 11 are symmetrically slidably installed on both sides of the upper end of the spraying vehicle 1, and the two sliders 11 are connected to the water pump 13 through a conduit 14. A plurality of spray heads 12 are provided on the outside of the sliders 11. The sliders 11 and each spray head 12 are connected and fixed by a universal adjustment mechanism 2. The universal adjustment mechanism 2 includes a spherical connector 24, a first connecting frame 21 connected to the slider 11 and a second connecting frame 22 connected to the spray head 12. The first connecting frame 21 and the second connecting frame 22 are staggered with each other, and the spherical connector 24 is rotatably installed on Between the first connecting frame 21 and the second connecting frame 22, a through cavity 23 is opened in the first connecting frame 21 and the second connecting frame 22 and is communicated with the inner cavity of the spherical connector 24. A positioning gear ring 251 is fixedly installed on the periphery of the spherical connector 24, and a positioning gear sleeve 252 is fixedly installed in the first connecting frame 21 and the second connecting frame 22. A positioning gear rod 25 is plugged and installed between adjacent positioning gear rings 251 and positioning gear sleeves 252. A movable rod 26 is plugged and installed on the upper and lower sides of the spherical connector 24 respectively. A support plate 264 is rotatably installed between the movable rod 26 and the positioning gear rod 25, and a first spring 267 is fixedly installed on the inside of the positioning gear rod 25.

[0023] The first connecting frame 21 and the second connecting frame 22 are provided with two symmetrically arranged limiting rotation holes 231 in their inner cavities, and the spherical connector 24 is provided with limiting rotation sleeves 241 rotatably connected to the limiting rotation holes 231 on four sides of its inner cavity.

[0024] The positioning gear sleeve 252 is fixedly installed on the inner side of the limiting rotation hole 231 , and the positioning gear ring 251 is fixedly installed in the limiting rotation sleeve 241 through a bracket. The spherical connector 24 has limiting holes 261 on the upper and lower sides, and the movable rod 26 is inserted into the limiting holes 261 .

[0025] A connecting seat 262 is provided inside the spherical connector 24, and limiting sleeves 265 are fixedly installed on the four outer sides of the connecting seat 262. Limiting rods 266 corresponding to the positions of each limiting sleeve 265 are fixedly installed on the inner sides of the four positioning gear rods 25. The corresponding limiting sleeves 265 and limiting rods 266 are plugged into each other, and a first spring 267 is fixedly installed between the limiting sleeves 265 and the limiting rods 266.

[0026] The specific working principle and usage of the present invention are explained in detail below: When the angle of the spray head 12 needs to be adjusted, the two movable rods 26 are pulled outward on the upper and lower sides of the spherical connector 24, and the positioning gear rod 25 is driven to retract into the positioning gear ring 251 through the support plate 264, so that the positioning gear rod 25 and the positioning gear sleeve 252 are separated from each other, thereby releasing the connection between the spherical connector 24 and the first connecting frame 21 and the second connecting frame 22. Then, the angle of the spray head 12 can be adjusted in the horizontal and vertical directions through the connection between the spherical connector 24 and the first connecting frame 21 and the second connecting frame 22. After the angle adjustment of the spray head 12 is completed, the movable rod 26 is released, and the positioning gear rod 25 is driven to reset outward under the action of the restorative deformation of the first spring 267, so that the positioning gear rod 25 and the positioning gear sleeve 252 are re-inserted, thereby achieving the effect of positioning the spray head 12.

[0027] Among them, a limited rotating seat 31 is fixedly installed on the upper end of the spraying vehicle 1, and a winding disk 3 is rotatably installed on the upper end of the limited rotating seat 31. The longitudinal section of the winding disk 3 is an I-shaped setting, and the catheter 14 is wound around the outer periphery of the winding disk 3; a first liquid guide hole 32 is opened in the limited rotating seat 31, and the first liquid guide hole 32 is communicated with the liquid outlet hole of the water pump 13, and a second liquid guide hole 33 is opened in the winding disk 3, and the outer end of the second liquid guide hole 33 is communicated with the catheter 14; the first liquid guide hole 32 and the second liquid guide hole 33 are both L-shaped, and the first liquid guide hole 32 and the second liquid guide hole 33 are L-shaped. The liquid guide holes 33 are connected to each other; a limited rotation groove 34 is provided at the upper end of the limited rotation seat 31, and a limited rotation ring 35 is fixedly installed at the lower end of the winding disk 3, and the limited rotation ring 35 is rotatably installed in the limited rotation groove 34; a second spring 36 is provided in the limited rotation groove 34, and a first clamping block 37 is fixedly installed on the inner side of the inner cavity of the limited rotation groove 34, and a second clamping block 38 is fixedly installed on the inner side of the limited rotation ring 35, the inner side of the second spring 36 is clamped with the outer side of the first clamping block 37, and the outer side of the second spring 36 is clamped with the inner side of the second clamping block 38.

[0028] When the spraying vehicle 1 drives the slider 11 to move through the motor and the threaded screw, the catheter 14 is driven to move accordingly, and the winding disk 3 is driven to rotate on the upper end of the limit rotating seat 31. In cooperation with the first clamping block 37 and the second clamping block 38, when the slider 11 moves away from the side of the winding disk 3, the second spring 36 can be driven to move and deform. When the slider 11 moves toward the side of the winding disk 3, the second spring 36 restores the deformation and drives the winding disk 3 to rotate, thereby winding the catheter 14, avoiding accumulation, knotting or dragging of the catheter 14, and protecting the catheter 14.

[0029] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.
