[0002] Construction dust control refers to a series of effective measures taken during construction activities to reduce the concentration of suspended dust particles in the air. Earthwork excavation, material handling, and building demolition in construction easily generate dust, which can harm the surrounding environment and residents' health. Common dust control methods include installing dust suppression devices on building walls, such as spray, mist, and electrostatic dust suppression devices, which use water mist to cause dust to settle or use electric fields to adsorb dust. Construction dust control is of great significance for protecting the environment, maintaining air quality, and complying with environmental regulations; it is an indispensable part of construction.

[0003] However, the current dust suppression devices for building walls have certain drawbacks: First, the nozzle height is inconvenient to adjust, making it difficult to adapt to walls of different heights and lacking versatility; second, the installation and disassembly of the nozzles are relatively cumbersome, making it difficult for staff to quickly replace and repair them, resulting in increased maintenance costs and time.

[0004] In response to this technical problem, this application proposes a dust suppression device for building walls. Utility Model Content

The sliding block 13 slides up and down. The front end of the threaded rod 4 is fixedly connected to a pulley 8. The two pulleys 8 are connected by the inner side of the belt. The front end of the right threaded rod 4 is fixedly connected to a handle 7. The right threaded rod 4 is rotated by the handle 7, and the left threaded rod 4 is rotated by the two pulleys 8 connected by the belt. The two sliding blocks 13 are rotatably connected to a rotating rod 15. The water pipe 11 is fixedly connected to the outer wall of the rotating rod 15. Gears 16 are fixedly connected to both ends of the rotating rod 15. Limiting rods 17 are inserted into the right side of the right sliding block 13 and the left side of the left sliding block 13. The rotating rod 15 is rotated by the gear 16, and the limiting rod 17 is inserted into the sliding block 13, so that the limiting rod 17 is between two adjacent teeth of the gear 16, thereby fixing the gear 16.

[0027] Reference Figure 1 , Figure 4 and Figure 5A fixing ring 19 is fixedly connected to the front side of the water supply pipe 11, and a metal ring 18 is fixedly connected to the rear side of the nozzle 12. The metal ring 18 is inserted into the fixing ring 19. By inserting the metal ring 18 into the fixing ring 19, the nozzle 12 is initially installed onto the water supply pipe 11. Two grooves are formed on the front side of the fixing ring 19, and a telescopic rod 20 is fixedly connected inside the grooves. An insert rod 22 is fixedly connected to the end of the telescopic rod 20. The insert rod 22 is inserted into the fixing ring 19. By inserting the insert rod 22 into the fixing ring 19, the metal ring 18 is fixed into the fixing ring 19, thereby fixing the nozzle 12 into the metal ring 18. A pressing plate 23 is fixedly connected to the outer wall of the water tank 1. A spring 21 is sleeved on the outer wall of the telescopic rod 20. One end of the spring 21 is connected to one side inside the groove, and the other end of the spring 21 is connected to one end of the insertion rod 22. The spring 21 is used to press the insertion rod 22 against the fixing ring 19, and the pressing plate 23 is used to disengage the insertion rod 22 from the fixing ring 19. A water pump 3 is installed on the bottom front side of the water tank 1. The output end of the water pump 3 is connected to the bottom side of the water supply pipe 11 through a hose 10.

Water is added to the water tank 1 through the water injection pipe 2.

[0028] Working principle: First, move the device to the wall where dust suppression is needed. Then, adjust the height of the nozzle 12 according to the height of the wall. When adjusting the height of the nozzle 12, rotate the handle 7 to rotate the right threaded rod 4. This, in turn, drives the left threaded rod 4 to rotate simultaneously via two pulleys 8 connected by a belt. This drives the rotating seat 14 to slide, causing the bottom end of the connecting rod 6 to slide. The top end of the connecting rod 6 then drives the sliding seat 13 to slide up and down, thereby adjusting the height of the water pipe 11, and consequently, the height of the nozzle 12. When the condition is good or bad, the gear 16 can be rotated to make the rotating rod 15 rotate. By inserting the limiting rod 17 into the slide block 13, the limiting rod 17 is positioned between two adjacent teeth on the gear 16, thereby fixing the gear 16. This allows the height of the water pipe 11 to be adjusted, and thus the height of the nozzle 12 to be adjusted, so that the nozzle 12 can meet the dust suppression requirements at different heights. When the nozzle 12 is clogged or needs to be replaced, the insert rod 22 can be disengaged from the fixing ring 19 by pressing the pressing plate 23. Then, the nozzle 12 can be grasped and the metal ring 18 can be pulled out of the fixing ring 19, thereby disassembling the nozzle 12 for repair or replacement.
