Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, it relates to a dust suppression device for building construction. Background Technology

[0002] In the construction industry, with increasingly stringent environmental protection requirements and improved worker health and safety awareness, dust suppression equipment has become an essential environmental protection device on construction sites. In scenarios that generate a large amount of dust, such as large-scale construction projects, road construction, and demolition operations, effectively controlling dust pollution is not only a mandatory requirement of environmental regulations but also an important means of improving the quality of the construction environment. However, most dust suppression devices on the market currently have significant shortcomings in practical applications, especially in terms of the lack of flexibility in adjusting the spray angle. The construction site environment is complex and changeable, and different areas and weather conditions require targeted adjustments to the spray coverage and direction. However, existing equipment often requires cumbersome bolt tightening or clip locking to fix the adjusted nozzle position. This operation is not only time-consuming and labor-intensive but may also cause the spray angle to shift due to insecure fixing, reducing the dust suppression effect.

[0003] In construction sites with high-intensity continuous operations, the adjustment efficiency of dust suppression equipment is directly related to the timeliness and effectiveness of dust control, which in turn affects the overall construction progress and the quality of the surrounding environment. Traditional dust suppression devices use manual knobs or bolts for fixing, which requires workers to carry special tools for adjustment. Moreover, it is difficult to operate at heights or in inaccessible locations, increasing safety risks. Utility Model Content

[0029] Please see Figures 1-5 A dust suppression device for construction engineering includes a trolley 1 with a spraying mechanism. The spraying mechanism includes a support frame 2, a rotating rod 3, an outer cylinder 4, a mounting frame 5, a fan 6, and an annular pipe 7.

Positioning block 12, abutting rod 13, threaded sleeve 14 and abutting sleeve 15, positioning plate 8 is fixed to the outer wall of support frame 2, fixing rod 9 is fixed to the top of rotating rod 3, mounting ring 10 is fixed to the outer wall of fixing rod 9 and slides in positioning plate 8, sliding holes 11 are provided in multiple sets distributed on the bottom surface of mounting ring 10, positioning block 12 slides in multiple sets of sliding holes 11, abutting rod 13 is fixed to the outer wall of multiple sets of positioning blocks 12 and slides in connection with mounting ring 10, threaded sleeve 14 threadedly connects to the outer wall of fixing rod 9, and abutting sleeve 15 is fixed to the outer wall of threaded sleeve 14.

[0030] A water tank 16 is fixedly installed inside the trolley 1. A water pump 17 is connected to the outer wall of the water tank 16. A delivery pipe 18 is connected between the output end of the water pump 17 and the annular pipe 7. The water pump 17 draws water from the water tank 16 and delivers the water to the annular pipe 7 through the delivery pipe 18, forming a complete water supply system to ensure the continuous and stable operation of the dust suppression device.

[0031] A guide plate 19 is fixedly mounted on the top surface of the trolley 1, and the bottom end of the support frame 2 is slidably connected to the guide plate 19. The bottom end of the support frame 2 slides on the surface of the guide plate 19 to achieve controlled rotation. The guide plate 19 provides stable support and restricts the movement trajectory of the support frame 2 to prevent the spray system from shaking.

[0032] A rotary motor 20 is fixedly installed on the inner side of the guide plate 19, and the output end of the rotary motor 20 is fixedly connected to the outer wall of the support frame 2. The rotary motor 20 drives the support frame 2 to rotate on the guide plate 19, so that the entire spraying system automatically swings horizontally, expanding the spray coverage area without manual intervention.

[0033] The inner wall of the annular pipe 7 has through holes 21, and multiple sets of through holes 21 are distributed on the inner wall of the annular pipe 7. The multiple sets of through holes 21 allow water to be sprayed evenly from the annular pipe 7, and combined with the action of the fan 6, a fine water mist is formed, achieving 360-degree all-round spraying and maximizing the dust suppression effect.

[0034] A handle 22 is fixedly installed on the outer wall of the outer cylinder 4. The handle 22 allows the operator to manually adjust the angle position of the outer cylinder 4, providing a human-machine interface that makes spray direction adjustment more intuitive and convenient, adapting to different working conditions.

[0035] Each of the multiple positioning blocks 12 is connected to a tension spring 23 between itself and the inner wall of the slide groove. The tension spring 23 provides a return force for the positioning block 12. When the threaded sleeve 14 is loosened, the tension spring 23 automatically pulls the positioning block 12 out of the positioning groove 30, realizing a quick unlocking function and simplifying the operation process.

[0036] A thrust bearing 24 is installed at the bottom of the abutment sleeve 15, and multiple positioning grooves 30 are opened in the positioning plate 8.

[0037] In this embodiment, water is pumped from the water tank 16 by the water pump 17 and then transported to the annular pipe 7 through the delivery pipe 18 for spraying. At the same time, the fan 6 is started to atomize and spray multiple sets of water through the outlet to reduce dust. The rotary motor 20 is started so that its output end drives the support frame 2 to rotate. The bottom end of the support frame 2 slides along the guide plate 19 to limit the support frame 2. The support frame 2 is then repeatedly oscillated to increase the spraying area of ​​the outer cylinder 4.

[0038] More specifically, when the longitudinal angle of the outer cylinder 4 needs to be adjusted, the handle 22 is pulled to make the outer cylinder 4 rotate along the support frame 2 via the rotating rod 3. After adjusting to the appropriate angle, the threaded sleeve 14 is rotated clockwise to engage with the fixed rod 9, so that the abutment sleeve 15 pushes the push bearing to abut against the top of the multiple sets of abutment rods 13. The multiple sets of abutment rods 13 push the positioning block 12 to slide along the slide groove and abut against the positioning groove 30. At the same time, the multiple sets of positioning blocks 12 stretch the multiple sets of tension springs 23 respectively, thus completing the positioning and fixing of the angle of the outer cylinder 4. When unlocking is required, the threaded sleeve 14 is rotated counterclockwise to make the thrust bearing 24 release the abutment against the multiple sets of abutment rods 13. The multiple sets of tension springs 23 pull the positioning block 12 to slide along the slide groove and disengage from the positioning groove 30, thus releasing the positioning of the rotating rod 3.

[0039] In summary, during use or operation of the overall equipment: water is pumped from the water tank 16 by the water pump 17, and then transported to the annular pipe 7 through the delivery pipe 18 for spraying. At the same time, the fan 6 is started to atomize and spray multiple sets of water through the outlet to reduce dust. The rotary motor 20 is started so that its output end drives the support frame 2 to rotate. The bottom end of the support frame 2 slides along the guide plate 19 to limit the support frame 2. The device then repeatedly swings the spraying lateral angle of the outer cylinder 4 to increase the spraying area.

[0040] When the longitudinal angle of the outer cylinder 4 needs to be adjusted, pull the handle 22 to make the outer cylinder 4 rotate along the support frame 2 via the rotating rod 3. After adjusting to the appropriate angle, rotate the threaded sleeve 14 clockwise to engage with the fixed rod 9, so that the abutment sleeve 15 pushes the push bearing to abut against the top of the multiple abutment rods 13. The multiple abutment rods 13 push the positioning block 12 to slide along the slide groove and abut against the positioning groove 30. At the same time, the multiple positioning blocks 12 stretch the multiple tension springs 23 respectively, completing the positioning and fixing of the angle of the outer cylinder 4. When unlocking is required, rotate the threaded sleeve 14 counterclockwise to make the thrust bearing 24 release the abutment against the multiple abutment rods 13. The multiple tension springs 23 pull the positioning block 12 to slide along the slide groove and disengage from the positioning groove 30, releasing the positioning of the rotating rod 3.
