Technical Field

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

[0002] Construction engineering refers to the engineering entity formed by the construction of various buildings and their ancillary facilities and the installation of supporting lines, pipelines and equipment. Construction sites often generate a lot of dust due to construction, and dust suppression devices are needed to reduce dust pollution at construction sites.

[0003] Current dust suppression methods typically involve installing water pipes on the upper part of the perimeter fencing around the construction site, spraying water mist from nozzles on these pipes to suppress dust. This method is complex to install, and once the location is fixed, it is inconvenient to adjust or move to target the center of the construction site. Furthermore, existing dust suppression devices lack effective protective structures; the nozzles and pipes cannot be properly stored when not in use, making them prone to damage. Therefore, a dust suppression device for construction projects is needed to address these problems. Utility Model Content

Through the threaded connection between the connecting inner pipes 8 and the connecting outer pipes 501, the intermediate nozzle 5 can be effectively connected with the first side nozzle 6 and the second side nozzle 601. The external water supply equipment can transport water to the intermediate nozzle 5, the first side nozzle 6 and the second side nozzle 601 through the connector pipe 9. Finally, the water is sprayed out through the nozzles 7 to achieve dust suppression. When not in use, the first side nozzle 6 and the second side nozzle 601 can be disassembled and locked in the bracket 4.

[0025] The height adjustment component 3 includes a limiting seat 301, a bidirectional screw 302, a drive block 303, and a U-shaped frame 306. Two limiting seats 301 are provided, each fixedly mounted on both ends of the bottom surface inside the protective frame 1. The bidirectional screw 302 is rotatably mounted between the two limiting seats 301. One end of the bidirectional screw 302 passes through the side wall of the protective frame 1 and is equipped with a handle 304. The threads at both ends of the bidirectional screw 302 are in opposite directions. Two drive blocks 303 are provided. Both drive blocks 303 are threadedly connected to the bidirectional screw 302. A sliding groove 102 is provided on the bottom surface of the inner side of the protective frame 1 between the two limit seats 301. The lower end of the drive block 303 is slidably connected to the sliding groove 102, and the upper end of the drive block 303 is rotatably connected to the cross support rod 305. By rotating the handle 304, the bidirectional screw 302 can be effectively driven to rotate. Under the limiting action of the sliding groove 102, the two drive blocks 303 can move along the bidirectional screw 302, moving closer to each other or further away from each other.

[0026] The cross support rod 305 is rotatably connected to a sliding connecting block at its upper end. The cross support rod 305 is slidably connected to the U-shaped frame 306 through the sliding connecting block. The bottom surface of the inner side of the protective frame 1 is provided with perforations 101 at both ends and outside the limiting seat 301 for the side wall of the U-shaped frame 306 to pass through. The intermediate spray pipe 5 is set on the upper surface of the U-shaped frame 306. By moving the driving block 303, the cross support rod 305 can be driven to work. When dust suppression is in operation, the cross support rod 305 can push the intermediate spray pipe 5 to rise for effective height adjustment. When not in operation, the cross support rod 305 pulls the intermediate spray pipe 5 to retract into the protective frame 1. The protective frame 1 can effectively play a protective role and extend the service life of the device.

[0027] The protective frame 1 has fixing components 2 at its lower ends on both sides. The fixing components 2 include brackets 201, threaded rods 202, and pressure plates 203. There are two brackets 201, which are respectively set at the middle of both sides of the protective frame 1. Fixing holes are opened on the bottom plate of the brackets 201. The threaded rods 202 are threadedly connected to the brackets 201. One end of the threaded rods 202 is connected to the pressure plates 203. The end of the threaded rods 202 away from the pressure plates 203 passes through the vertical wall of the brackets 201 and is equipped with a knob 204. The fixing holes facilitate the installation and fixing of the brackets 201. The brackets 201 can effectively support the protective frame 1 and ensure the overall stability. At the same time, the protective frame 1 can be placed on the fence of the construction site. By rotating the knob 204, the threaded rods 202 can be rotated and moved. During the movement of the threaded rods 202, the pressure plates 203 can be pushed to clamp the fence. The operation is simple.

[0028] Working principle: Based on the required dust suppression location, a fixed bracket 201 is installed through a fixing hole. The bracket 201 can effectively support the protective frame 1, ensuring overall stability. At the same time, the protective frame 1 can be placed on the construction site fence. By rotating the knob 204, the threaded rod 202 can be rotated and moved. During the movement of the threaded rod 202, the pressure plate 203 can be pushed to clamp the fence. The operation is simple. Through the threaded connection between the inner pipe 8 and the outer pipe 501, the intermediate spray pipe 5 can be effectively connected to the first side spray pipe 6 and the second side spray pipe 601. The external water supply equipment can deliver water to the intermediate spray pipe 5, the first side spray pipe 6 and the second side spray pipe 601 through the connector pipe 9. Finally, the water is sprayed out through the nozzle 7 to achieve dust suppression.

[0029] Furthermore, rotating the handle 304 can effectively drive the bidirectional screw 302 to rotate. Under the limiting action of the slide groove 102, the two drive blocks 303 move along the bidirectional screw 302, moving closer or further apart from each other. The movement of the drive blocks 303 can drive the cross support rod 305 to work. When dust suppression is in operation, the cross support rod 305 can push the middle nozzle 5 to rise for effective height adjustment. When not in operation, the first side nozzle 6 and the second side nozzle 601 can be disassembled and locked on the bracket 4. The cross support rod 305 pulls the middle nozzle 5 to retract into the protective frame 1. The protective frame 1 can effectively play a protective role and extend the service life of the device.
