Technical Field

[0001] This invention belongs to the technical field of construction dust suppression equipment, specifically relating to a dust suppression device for construction sites. Background Technology

[0002] Dust generated at construction sites in cities inevitably impacts the surrounding environment. Dust control at construction sites is one of the problems that needs to be addressed in construction management. Currently, the common solution to dust control at construction sites is to install sprinkler systems to suppress dust, which is a relatively convenient and effective method. Existing sprinkler systems are usually installed on the upper side of construction guardrails, using high-pressure atomizing nozzles to suppress dust in the construction site. However, installation requires the sequential arrangement and stabilization of pipes, which takes a long time and reduces the installation efficiency of the dust suppression system. Therefore, this paper proposes a dust suppression device for construction sites to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a dust suppression device for construction sites to solve the problems existing in the background art.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0005] A dust suppression device for construction sites includes a guardrail, a support frame fixedly mounted on the guardrail, a column fixedly mounted between adjacent supports, a protective frame on the outside of the support, a water channel opened on the rear side inside the protective frame, a water channel connecting component between adjacent protective frames, and a dust suppression mechanism on the front side of the protective frame.

[0006] The dust suppression mechanism includes a crossbeam, a water bladder, and several high-pressure atomizing nozzles.

A limiting component is provided between the crossbeam and the protective frame. The rear end of the crossbeam has a receiving groove, and the water bladder is assembled inside the receiving groove. The rear side of the water bladder is fixedly connected to the rear end of the assembly groove, and the front side of the water bladder is fixedly connected to the front end of the receiving groove. A connecting ring is fixedly provided between the water bladder and the assembly groove. The assembly groove has a slot communicating with the water channel. A sealing rod is fixedly provided at the rear end of the inner side of the water bladder and is slidably connected to the connecting ring. Several high-pressure atomizing nozzles are evenly distributed on the front side of the crossbeam, and each high-pressure atomizing nozzle communicates with the water bladder.

[0007] Preferably, the limiting component includes a slide bar and a limiting block. A cross groove is provided on the upper side of the guard frame. The slide bar is slidably disposed inside the cross groove. The limiting block is fixedly assembled in the middle of the slide bar. An L-shaped limiting groove is provided on the upper side of the crossbeam. The limiting block slides and matches the L-shaped limiting groove.

[0008] Preferably, the waterway connection component includes a connecting hose, with sealing rings fixed at both ends of the connecting hose, and both sealing rings are rotatably provided with threaded rings. The left and right sides of the protective frame are provided with threaded grooves that are threadedly connected to the threaded rings, and both threaded grooves are connected to the waterway.

[0009] Preferably, both the column and the bracket are fixedly provided with a plurality of mounting ears, each of the mounting ears having a mounting hole, and the lower end of the column is fixedly provided with a base, the base having a plurality of pile holes.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Example:

[0028] like Figure 1-3As shown, a dust suppression device for construction sites according to the present invention includes a guardrail 1, with a support 11 fixedly mounted on the guardrail 1. The support 1 is cross-shaped, which provides better support for the guardrail 1. The support 1 has a hollow design in the middle. A column 12 is fixedly mounted between adjacent supports 11. Each column 12 and support 11 is fixedly provided with several mounting ears 41. The mounting ears 41 are securely connected by bolts and nuts, ensuring a stable connection between the column 12 and the adjacent support 11. Each mounting ear 41 has a mounting hole 42. A base 43 is fixedly mounted at the lower end of the column 12, and the base 43 has several posts. Hole 44, support 45 is fixedly provided on the lower front side of bracket 1, and a protective frame 13 is provided on the outer side of bracket 11. A water channel 131 is opened on the rear side of the inner side of the protective frame 13. A water channel connecting component is provided between adjacent protective frames 13. The water channel connecting component includes a connecting hose 31. A sealing ring 32 is fixedly provided at both ends of the connecting hose 31. Both sealing rings 32 are rotatably provided with threaded rings 33. Threaded grooves 34 are opened on the left and right sides of the protective frame 13 and are threadedly connected to the threaded rings 33. Both threaded grooves 34 are connected to the water channel 131. The adjacent water channel 131 can be connected through the connecting hose 31. A dust suppression mechanism is provided on the front side of the protective frame 13.

[0029] like Figure 6-9 As shown, the dust suppression mechanism includes a crossbeam 14, a water bladder 141, and several high-pressure atomizing nozzles 142. A mounting groove 143 is provided at the front end of the protective frame 13. The crossbeam 14 is slidably mounted in the mounting groove 143, and can only slide back and forth within the mounting groove 143. A limiting component is provided between the crossbeam 14 and the protective frame 13. A receiving groove 144 is provided at the rear end of the crossbeam 14. The water bladder 141 is mounted inside the receiving groove 144. The rear side of the water bladder 141 is fixedly connected to the rear end of the mounting groove 143, and the front side of the water bladder 141 is fixedly connected to the inside of the receiving groove 144. The front end of the water bladder 141 is fixedly connected to the water bladder 141. A connecting ring 1411 is fixedly provided between the water bladder 141 and the assembly groove 143. The assembly groove 143 is provided with a slot 1431 that communicates with the water channel 131. A sealing rod 1412 is fixedly provided at the rear end of the inner side of the water bladder 141 and is slidably connected to the connecting ring 1411. A sealing ring 1413 is fixedly sleeved on the sealing rod 1412. A guide slope 1414 is provided at the rear end of the sealing rod 1412. Several high-pressure atomizing nozzles 142 are evenly arranged on the front side of the crossbeam 14. Several high-pressure atomizing nozzles 142 are all connected to the water bladder 141.

[0030] like Figure 4-5 As shown, the limiting component includes a slide bar 21 and a limiting block 22. A cross groove 23 is provided on the upper side of the guard frame 13. The slide bar 21 is slidably disposed in the cross groove 23. The limiting block 22 is fixedly assembled in the middle of the slide bar 21. An L-shaped limiting groove 24 is provided on the upper side of the crossbeam 14. The limiting block 22 and the L-shaped limiting groove 24 slide and match.

[0031] When constructing the guardrail 1 at the construction site, columns 12 can be pre-erected to form an initial frame. Then, several supports 11 are installed securely on the sides of the columns 12. Adjacent supports 11 are secured with columns 12 and supports 45 to improve the stability of the supports 11 and the guardrail 1. After the guardrail 1 and supports 11 are installed, the adjacent waterway 131 is connected through the connecting hose 31. At this point, the installation of the device is complete. The installation is quick and the structure is stable. When construction is carried out at the construction site, water is introduced into the waterway 131. The water can be transmitted to the high-pressure atomizing nozzle 142 through the waterway 131 and the water bag 141. Finally, the high-pressure atomizing nozzle 142 is used to suppress dust at the construction site.

[0032] Some construction sites are large, and in larger construction sites, only a portion of the area often needs to be constructed. Therefore, some guardrail sections far from the construction site do not require dust suppression. In this case, simply move the crossbeam 14 into the assembly slot 143 until the sealing rod 1412 slides into the connecting ring 1411 and the slot 1431. The sealing rod 1412 seals the connecting ring 1411, preventing water from the water channel 131 from entering the water bladder 141. While moving the crossbeam 14, the limiting block 22 slides into one side of the L-shaped limiting groove 24. At this point, simply slide the slider 21 to the left to move the limiting block 22 into the other side of the L-shaped limiting groove 24. This allows the crossbeam 1 to be properly positioned. 4. Limit the operation so that the high-pressure atomizing nozzle 142 at this location will not work and will not affect the connection between adjacent water channels 131. When a high-pressure atomizing nozzle 142 needs to work, simply slide the slider 21 to the right. Then the water pressure in the water channel 131 will push the sealing rod 1412 to move until the water in the water channel 131 fills the water bag 141. The high-pressure atomizing nozzle 142 at this location can then start working. The operation is convenient. By adjusting the crossbeam 14, the high-pressure atomizing nozzles 142 can be made independent of each other and can be turned on and off independently without affecting the transportation of dust suppression water between adjacent water channels 131.

[0033] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
