Description

Technical Field

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

[0002] Currently, dust pollution is a widespread problem during construction projects. With the acceleration of urbanization and the booming development of the construction industry, dust generated at construction sites has a serious impact on the atmospheric environment, the health of surrounding residents, and the city's image. Dust not only reduces air quality and increases the concentration of harmful substances such as PM2.5 in the atmosphere, but it can also cause respiratory diseases and other health problems. Furthermore, dust pollutes and damages construction equipment and materials, increasing construction costs.

[0003] Traditional dust control measures in construction projects mainly include water spraying, setting up barriers, and dust nets. However, these methods have many limitations. While water spraying can reduce dust generation to some extent, it requires a large amount of water and its effectiveness is limited by weather conditions, such as dry or windy weather. Setting up barriers can block some dust from spreading, but it cannot completely eliminate the dust source and also affects ventilation and lighting at the construction site. Although dust nets can intercept some dust, the installation and dismantling process is cumbersome, and it is difficult to flexibly adjust them according to the height and range of dust flying at the construction site.

[0004] Therefore, we propose a dust control device for construction projects that can efficiently intercept and flexibly control dust, and dynamically adjust it according to the actual conditions of the construction site to minimize dust pollution. Utility Model Content

[0005] The purpose of this utility model is to provide a dust control device for construction engineering, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust control device for construction engineering, comprising a mounting base, wherein multiple sets of mounting bases are provided, and each set of mounting bases is installed on the top of a wall by expansion bolts. Each set of mounting bases has a column fixedly installed on its top, and each set of mounting bases has a pulley fixedly installed on its top. Each set of columns has a limiting groove on both sides, and a dust control mechanism is installed between adjacent sets of limiting grooves. Each set of dust control mechanisms has a steel wire rope fixedly installed on both sides of its top, and the multiple sets of steel wire ropes are movably connected to each set of pulleys.

[0007] Optionally, the dust control mechanism includes a first slider that is slidably installed on the top of both sets of limiting slide grooves, a crossbar that is fixedly installed between the two sets of first sliders, three sets of equidistant clamps that are fixedly installed on the crossbar, and a first spray pipe that is fixedly installed on the other side of the three sets of clamps. The other ends of the multiple sets of wire ropes are all wound with the winch take-up roller.

[0008] By adopting the above technical solutions, dust can be reduced efficiently.

[0009] Optionally, the bottom of the multiple sets of steel wire ropes are fixedly installed to the top of each set of first sliders, and the top of each set of first nozzles is connected to multiple sets of equidistantly distributed atomizing nozzles.

[0010] Optionally, multiple sets of equidistantly distributed second sliders are slidably installed in each set of limiting slide grooves, and a counterweight rod is fixedly installed between adjacent sets of second sliders.

[0011] By adopting the above technical solution, each set of counterweight rods can slide up and down.

[0012] Optionally, a dustproof net is fixedly installed between each pair of adjacent counterweight bars, and a dust-blocking net is installed between the top counterweight bar and each set of crossbars.

[0013] By adopting the above technical solutions, flying dust and fog can be intercepted.

[0014] Optionally, a second spray pipe is fixedly installed in the middle of each of the two adjacent sets of columns, and multiple sets of equally spaced cleaning nozzles are connected to the side wall of each set of the second spray pipes. Each of the adjacent sets of cleaning nozzles corresponds to a single set of dustproof nets.

[0015] By adopting the above technical solution, the dustproof net can be cleaned.

[0016] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0017] The technical solution of this application involves driving a winch to wind up multiple sets of wire ropes. Each set of wire ropes pulls the first slider upward within the limiting groove, simultaneously causing the crossbar between the two adjacent sets of first sliders to slowly move upward. This not only unfolds the dustproof net between the two adjacent sets of counterweight bars, increasing the range of dust and mist interception, but also raises the height of the first nozzle on the crossbar. The operator can control the height of each set of first nozzles based on the height of dust and mist flying in the construction project, ensuring that the atomized water sprayed from each set of first nozzles is aligned with the flying dust and mist, greatly improving dust suppression efficiency.

[0018] Each pair of adjacent columns has a second spray pipe fixedly installed in the middle, and each second spray pipe has multiple sets of equally spaced cleaning nozzles connected to its side wall. When the operator drives the winch to release multiple sets of wire ropes, each set of dustproof nets will automatically move down by its own weight, and the valve on the water source will open simultaneously to deliver water to the second spray pipe. The water droplets sprayed from the multiple sets of cleaning nozzles can clean the moving dustproof nets, ensuring the cleanliness of the multiple sets of dustproof nets for the next use.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a dust control device for construction engineering, including a mounting base 1, of which multiple sets are provided. Each set of mounting bases 1 is installed on the top of a wall using expansion bolts. A column 11 is fixedly installed on the top of each set of mounting bases 1, and a pulley 12 is fixedly installed on the top of each set. Limiting grooves 2 are provided on both sides of each set of columns 11. A dust control mechanism is installed between adjacent sets of limiting grooves 2. Steel wire ropes 25 are fixedly installed on both sides of the top of each set of dust control mechanisms. The multiple sets of steel wire ropes 25 are movably connected to each set of pulleys 12. Next, the dust suppression mechanism includes a first slider 21 that is slidably installed on the top of both sets of limiting slide grooves 2, a crossbar 22 fixedly installed between the two sets of first sliders 21, three sets of equidistant clamps 23 fixedly installed on the crossbar 22, and a first nozzle 24 fixedly installed on the other side of the three sets of clamps 23. The other ends of multiple sets of steel wire ropes 25 are all wound with the winding roller of the winch, which can effectively reduce dust. The bottom of the multiple sets of steel wire ropes 25 is fixedly installed on the top of each set of first sliders 21, and multiple sets of equidistant atomizing nozzles are connected to the top of each set of first nozzles 24.

[0025] When the winch winds up multiple sets of wire ropes 25, each set of wire ropes 25 pulls the first slider 21 upward within the limiting groove 2, simultaneously causing the crossbar 22 between two adjacent sets of first sliders 21 to slowly move upward. This not only unfolds the dustproof net 32 ​​between two adjacent sets of counterweight bars 31, increasing the range of dust and mist interception, but also raises the height of the first nozzle 24 on the crossbar 22. The operator can control the height of each set of first nozzles 24 based on the height of dust and mist flying in the construction project, ensuring that the atomized water sprayed from each set of first nozzles 24 is aligned with the flying dust and mist, greatly improving dust suppression efficiency.

[0026] In this technical solution, a second nozzle 33 is fixedly installed in the middle of each of the two adjacent sets of columns 11. Each set of second nozzles 33 has multiple sets of equally spaced cleaning nozzles 34 connected to its side wall. The multiple sets of cleaning nozzles 34 are all corresponding to a single set of dustproof nets 32, which can clean the dustproof nets 32.

[0027] When the operator drives the winch to release multiple sets of wire ropes 25, each set of dustproof nets 32 will automatically move down by the weight of its own weight on the counterweight rod 31. At the same time, the valve on the water source will be opened to deliver water to the second spray pipe 33. The water droplets sprayed from multiple sets of cleaning nozzles 34 can clean the moving dustproof nets 32 and ensure the cleanliness of the multiple sets of dustproof nets 32 for the next use.

[0028] In this technical solution, multiple sets of equidistantly distributed second sliders 3 are slidably installed in each set of limiting slide grooves 2. A counterweight rod 31 is fixedly installed between each pair of adjacent sets of second sliders 3, so that each set of counterweight rods 31 can slide up and down. A dustproof net 32 ​​is fixedly installed between each pair of adjacent sets of counterweight rods 31. A dust-blocking net is installed between the top counterweight rod 31 and each set of crossbars 22, which can intercept flying dust and mist.

[0029] When the wire rope 25 is wound up, it can pull multiple sets of second sliders 3 to move upward along the limiting groove 2. Conversely, when the wire rope 25 is unwound, the weight of each set of counterweight rods 31 can push each set of second sliders 3 to move downward along the limiting groove 2, thereby enabling the dustproof net 32 ​​to be unfolded and wound up.

[0030] In use, after installing the device on the top of the outer perimeter wall of the construction project, opening the water valve allows water to be supplied to multiple sets of first nozzles 24. Multiple atomizing nozzles on each set of first nozzles 24 spray atomized water to suppress surrounding dust and mist. Simultaneously, as the winch winds up multiple sets of wire ropes 25, each set of wire ropes 25 pulls the first slider 21 upward within the limiting groove 2, synchronously causing the crossbar 22 between adjacent sets of first sliders 21 to slowly move upward. This not only unfolds the dustproof net 32 ​​between adjacent sets of counterweights 31, increasing the range of dust and mist interception, but also raises the height of the first nozzles 24 on the crossbar 22. This allows the operator to see through the dust and mist flying around the construction project. The height of each first nozzle 24 is controlled to ensure that the atomized water sprayed from each first nozzle 24 is aligned with the flying dust mist, greatly improving the dust suppression efficiency. At the same time, a second nozzle 33 is fixedly installed in the middle of each of the two adjacent columns 11, and multiple sets of equally distributed cleaning nozzles 34 are connected to the side wall of each second nozzle 33. When the operator drives the winch to release multiple sets of wire ropes 25, each set of dustproof nets 32 will automatically move down by the weight of its own weight on the counterweight rod 31, and the valve on the water source will be opened simultaneously to deliver water to the second nozzles 33. The water droplets sprayed from the multiple sets of cleaning nozzles 34 can clean the moving dustproof nets 32, ensuring the cleanliness of the multiple sets of dustproof nets 32 for the next use.
