Description

Technical Field

[0002] Dust suppression devices are widely used in various construction sites, workshops, coal yards, and other places with severe dust pollution. Dust generated during construction projects can seriously affect the surrounding environment and the health of workers. Dust not only affects air quality but can also cause respiratory diseases and other health problems. Dust suppression devices can effectively reduce dust dispersion and protect the environment and workers' health; therefore, there is a need to develop a dust suppression device for construction projects.

[0003] Construction dust suppression devices atomize water into tiny particles. These water mist particles can quickly adsorb dust particles in the air, forming larger particle clusters that settle to the ground under gravity. This effectively reduces suspended particulate matter in the air, improves the construction environment, and enhances project quality. In previous technologies, the spray angle of water sprayers was fixed, which may have resulted in a limited spray area and thus affected the dust suppression effect. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 and Figure 2This utility model provides an embodiment of a dust suppression device for engineering construction, comprising a lifting plate 1 and a base box 18. A base plate 2 is fixedly connected to the upper surface of the lifting plate 1. A second motor 4 is fixedly connected to the upper surface of the base plate 2. A rotating shaft 7 is fixedly installed at the output end of the second motor 4. A support plate 5 is rotatably connected to the outer wall of the rotating shaft 7. The lower surface of the support plate 5 is fixedly connected to the upper surface of the lifting plate 1. A rotating frame 8 is fixedly connected to the outer wall of the rotating shaft 7. A rotating shaft 10 is rotatably connected inside the rotating frame 8. A first motor 3 is fixedly connected to the upper surface of the base plate 2. A worm gear 6 is fixedly installed at the output end of the first motor 3. The outer wall of the worm gear 6 is rotatably connected to the inside of the support plate 5. A rotating shaft 10 is fixedly connected to the outer wall of the worm gear 6. The outer wall of the rotating sleeve 9 is rotatably connected to the inside of the rotating frame 8. The tooth end of the worm gear 6 is meshed with the worm wheel 11. The inside of the worm wheel 11 is fixedly connected to the outer wall of the rotating shaft 10. The outer wall of the rotating shaft 10 is provided with a water spraying assembly for spraying water to suppress dust. The water spraying assembly includes a fixed frame 12. The inside of the fixed frame 12 is fixedly connected to the outer wall of the rotating shaft 10. The upper surface of the fixed frame 12 is fixedly connected to a water sprayer 13. The outer wall of the bottom box 18 is fixedly connected to a placement plate 14. The upper surface of the placement plate 14 is fixedly connected to a water storage tank 15. The inside of the water storage tank 15 is fixedly connected to a water pump 16. The output end of the water pump 16 is fixedly connected to a water pipe 17. The outer wall of the water pipe 17 is fixedly connected to the inside of the water sprayer 13.

[0024] Specifically, the lifting plate 1 fixes the position of the base plate 2, which in turn supports the first motor 3 and the second motor 4. Starting the second motor 4 drives the rotating shaft 7 to rotate. The support plate 5 supports the rotating shaft 7, and the lifting plate 1 also fixes its position. The rotation of the rotating shaft 7 drives the rotating frame 8 to rotate. The worm gear 6 fixes the position of the rotating sleeve 9, which supports the rotating frame 8. The rotating frame 8 supports the rotating shaft 10. Thus, when the rotating frame 8 rotates with the support of the rotating shaft 7 and the rotating sleeve 9, the rotating shaft 10 drives the fixed frame 12 to rotate, and the rotating shaft 10 fixes the fixed frame 12. Therefore, when the fixed frame 12 rotates, it drives the water sprayer 13 to... The rotating position is achieved by starting the first motor 3, which drives the worm gear 6 to rotate. Simultaneously, the support plate 5 supports the worm gear 6. When the worm gear 6 rotates, it drives the meshing worm wheel 11 to rotate synchronously. The rotating shaft 10 supports and fixes the worm wheel 11, allowing the rotating shaft 10 to drive the fixing frame 12 to rotate synchronously. The fixing frame 12 then drives the water sprayer 13 to rotate and adjust its angle. The base box 18 fixes the position of the placement plate 14, which in turn fixes the position of the water storage tank 15. Starting the water pump 16 allows water stored in the water storage tank 15 to be transported to the water sprayer 13 through the water pipe 17, ensuring that the water mist can evenly cover a larger area and effectively reduce the dust content in the air.

[0025] Reference Figure 3 and Figure 4 The bottom box 18 is rotatably connected to a threaded shaft 20. The outer wall of the threaded shaft 20 is fixedly connected to a handle 19. The bottom box 18 is provided with a sliding groove 30. The outer wall of the threaded shaft 20 is threadedly connected to a threaded block 28. The outer wall of the threaded block 28 is fixedly connected to a sliding shaft 29. The outer wall of the sliding shaft 29 is slidably connected to the inner wall of the sliding groove 30. The outer wall of the sliding shaft 29 is rotatably connected to a rotating plate 25. The inside of the rotating plate 25 is fixedly connected to a traction shaft 24. The outer wall of the traction shaft 24 is rotatably connected to a second rotating rod 26.

[0026] Specifically, rotating the throttle 19 drives the threaded shaft 20 to rotate inside the base box 18. When the base box 18 rotates, it drives the threaded block 28 to move inside the base box 18. The movement of the threaded block 28 drives the sliding shaft 29 to slide within the sliding groove 30 to prevent deviation. When the sliding shaft 29 moves to a new position, it drives the rotating plate 25 to rotate. When the rotating plate 25 rotates, the traction shaft 24 drives the second rotating rod 26 to rotate.

[0027] Reference Figure 3 and Figure 4 The outer wall of the second rotating rod 26 is rotatably connected to the first support shaft 22. The outer wall of the first support shaft 22 is fixedly connected to the fixed plate 21. The lower surface of the fixed plate 21 is fixedly connected to the upper surface of the base box 18. The inner wall of the second rotating rod 26 is rotatably connected to the first fixed shaft 31. The outer wall of the first fixed shaft 31 is fixedly connected to the support block 27. The upper surface of the support block 27 is fixedly connected to the lower surface of the lifting plate 1. The inner wall of the support block 27 is fixedly connected to the second fixed shaft 33. The outer wall of the second fixed shaft 33 is rotatably connected to the first rotating rod 23. The outer wall of the first rotating rod 23 is rotatably connected to the second support shaft 32. The outer wall of the second support shaft 32 is fixedly connected to the inner wall of the fixed plate 21.

[0028] Specifically, the first support shaft 22 supports the position of the second rotating rod 26, and the base box 18 fixes the position of the fixing plate 21. The fixing plate 21 fixes the positions of the first support shaft 22 and the second support shaft 32. Thus, when the second rotating rod 26 rotates smoothly, the first fixing shaft 31 drives the support block 27 to rise and fall. At the same time, the support block 27 fixes the positions of the first fixing shaft 31 and the second fixing shaft 33. Thus, when the support block 27 rises and falls, the second fixing shaft 33 drives the first rotating rod 23 to rotate under the support of the second support shaft 32. The rotation of the first rotating rod 23 further stabilizes the position of the support block 27. Therefore, the support block 27 supports and drives the lifting plate 1 to adjust its height.

[0029] Working principle: In use, the water pump 16 is first started, which transports water stored in the water tank 15 to the sprayer 13 via the water pipe 17, thereby spraying water to suppress dust at the construction site. When the rotation angle of the sprayer 13 needs to be adjusted, the second motor 4 is started, which drives the rotating shaft 7 to rotate under the support of the support plate 5. The rotation of the rotating shaft 7 supports and drives the connected rotating frame 8 to rotate synchronously. Simultaneously, the rotating shaft 7 and the rotating sleeve 9 support the position of the rotating frame 8, which in turn supports the position of the rotating shaft 10. Therefore, when the rotating frame 8 rotates, the rotating shaft 10 supports and drives the fixed frame 12 to rotate, which in turn drives the sprayer 13 to rotate back and forth to adjust its angle. When the spray angle is 13, starting the first motor 3 can drive the worm 6 to rotate under the support of the support plate 5. The rotation of the worm 6 can drive the worm wheel 11 to rotate synchronously. The rotating shaft 10 can support the position of the worm wheel 11. Thus, when the worm wheel 11 rotates, the rotating shaft 10 can drive the fixed frame 12 to rotate synchronously. Therefore, the rotation of the fixed frame 12 can drive the water sprayer 13 to rotate left and right. By adjusting the spray angle of the water sprayer 13, it can be ensured that the water mist can cover a wider area, thereby more effectively reducing the dust concentration in the air. This adjustment function allows the dust suppression device to adapt to different construction environments and needs, improve the dust suppression effect, and at the same time avoid the dead angle of water spray caused by the fixed spray angle, ensuring the comprehensiveness and uniformity of dust suppression.

[0030] When the height of the water sprayer 13 needs to be adjusted, first turn the handle 19 to drive the threaded shaft 20 to rotate inside the base box 18. When the threaded shaft 20 is turned, the threaded block 28 that cooperates with the threaded shaft 20 will move accordingly. As the threaded block 28 moves, it can drive the sliding shaft 29 to slide within the inner wall of the sliding groove 30. Thus, the movement of the sliding shaft 29 can drive the rotating plate 25 to rotate. When the rotating plate 25 rotates, the traction shaft 24 drives the second rotating rod 26 to rotate under the support of the first support shaft 22. When the second rotating rod 26 rotates, the first fixed shaft 31 can drive the support block 27 to rise. The lifting plate 1 is raised and lowered synchronously by the moving support of the support block 27. At the same time, when the support block 27 is raised and lowered, the first rotating rod 23 can be rotated by the second fixed shaft 33 under the support of the second support shaft 32. Meanwhile, the fixed plate 21 can fix the position of the first support shaft 22 and the second support shaft 32. The rotation of the first rotating rod 23 can more stably support and drive the support block 27 and the lifting plate 1 to raise and lower. The environment of the construction site is often complex and changeable. The design of the adjustable water sprayer 13 can ensure that the water mist can cover the dust at different heights, thereby improving the dust coverage rate and reducing the impact of dust on the surrounding environment.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
