Abstract
Description
Technical Field
[0001] This utility model specifically relates to an environmentally friendly dust control device for civil construction, belonging to the technical field of dust control equipment for civil construction. Background Technology
[0002] During civil engineering construction, the dust generated not only pollutes the surrounding air environment but also poses a threat to the respiratory health of on-site construction workers and nearby residents. With increasing public awareness of environmental protection and increasingly stringent government policies on dust control at construction sites, implementing efficient and environmentally friendly dust control measures has become an indispensable part of modern construction management.
[0003] Currently, in urban construction sites, since most construction activities are carried out in open environments, a common method to suppress dust dispersion is to install fixed sprinkler systems on the construction site fences, achieving localized dust reduction. However, most of these sprinkler systems are fixed structures with limited coverage, making it difficult to effectively target the central areas of the construction site. For core work areas far from the fences, additional mobile or independent dust collection equipment is often required to achieve comprehensive dust control.
[0004] This layout has obvious shortcomings: the fixed spray system cannot be flexibly adjusted in position, resulting in poor dust suppression in the central area; while adding other dust removal equipment increases construction costs and management difficulty. Utility Model Content

A threaded nail is threaded inside the mounting plate, and a threaded hole matching the size of the threaded nail is opened on the surface of the enclosure. The threaded hole is located on the rotation trajectory of the fixing plate.
[0009] Furthermore, a sunshade net is provided on the top surface of the rubber belt, and a second winding assembly is wound around the other side of the sunshade net.

The conveying shaft of the second winding wheel is fixedly connected to the first gear. The surface of the first gear meshes with the surface of the second gear. The interior of the second gear is driven by the output shaft of the first motor. The surface of the first motor is fixedly connected to the second support frame.
[0010] Furthermore, the first winding assembly includes a first winding wheel, a second synchronous wheel, a synchronous belt, and a first synchronous wheel. The shaft of the first winding wheel is rotatably connected to a first support frame. The bottom of the first support frame is fixedly connected to the outer side of the enclosure. One side of the rubber belt is wound around the surface of the first winding wheel. The shaft surface of the first winding wheel is fixedly connected to the second synchronous wheel. The surface of the second synchronous wheel is rotatably connected to the surface of the synchronous belt. One side of the synchronous belt is rotatably connected to the first synchronous wheel. The interior of the first synchronous wheel is fixedly connected to the shaft of the second winding wheel.
[0011] Furthermore, the limiting seat is provided with a locking assembly for fixing the sunshade net and the rubber strip inside. The locking assembly includes a fixing block and a threaded rod. The bottom of the limiting seat is provided with a fixing groove. The rubber strip and the sunshade net are inserted into the fixing groove.

[0015] Beneficial effects:
[0016] This application utilizes a hook to pull a connecting plate, extending the pull rope. The hook is then inserted into a fixing hole. A second motor, via a fourth and third gear, drives a rotating rod. This rotating rod, in turn, drives a third winding wheel to wind the pull rope. The pull rope, through the hook, fixing hole, and limit seat, pulls the rubber belt and shade net, extending them to cover the construction site. The silicone atomizing nozzles inside the rubber belt are aimed at the construction site. When construction is underway in a specific area, the water supply system in that area is activated, supplying water via a flexible hose. The water then enters the silicone atomizing nozzles, causing them to spray water mist, removing dust from the entire construction site. The shade net, when erected, effectively blocks direct sunlight, reducing summer site temperature and improving worker comfort. It also reduces the risk of equipment aging, overheating, or performance degradation due to prolonged exposure to sunlight.
[0017] In this application, the threaded pin is rotated to disengage from the threaded hole, releasing the fixed connection to the fixing plate. Then, the fixing plate is rotated to bring the mounting plate into contact with the ground. The threaded pin is then inserted into the ground through the mounting plate to complete the fixed connection between the mounting plate and the ground, achieving the effect of quick installation and disassembly of the enclosure.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-7 As shown, an environmentally friendly dust control device for civil construction includes several enclosure panels 1 for civil construction. A fixed plate 2 is rotatably connected to the outer side of the enclosure panel 1, and an mounting plate 3 is fixedly connected to the bottom of the fixed plate 2. A threaded nail 4 is threadedly connected to the inside of the mounting plate 3. A threaded hole 5 matching the size of the threaded nail 4 is opened on the surface of the enclosure panel 1. The threaded hole 5 is located on the rotation trajectory of the fixed plate 2. By setting up the fixed plate 2, the mounting plate 3, and the threaded nail 4, the threaded nail 4 can be rotated to disengage from the inside of the threaded hole 5, releasing the fixed connection to the fixed plate 2. Then, the fixed plate 2 is rotated to drive the mounting plate 3 to contact the ground. Then, the threaded nail 4 passes through the mounting plate 3 and inserts into the ground to complete the fixed connection between the mounting plate 3 and the ground.
[0028] In this application, a first guide wheel 14 is rotatably connected to the outer side of each enclosure 1. A second guide wheel 141, rotatably connected to the enclosure 1, is located above the first guide wheel 14. Multiple rubber bands 16 are provided on the surfaces of the first guide wheel 14 and the second guide wheel 141. A flexible hose 161 is fixedly connected inside each rubber band 16. The flexible hose 161 passes through the rubber band 16 and is inserted into the interior of the first take-up reel 13. One end of the flexible hose 161, passing through the center of the shaft of the first take-up reel 13, is connected to a water supply pipe. The water supply pipe and the end of the flexible hose 161 passing through the first take-up reel 13 are rotatably connected. The water supply pipe is connected to a water supply mechanism, which is the flexible hose 161. The water supply hose 161 is fixedly connected to a silicone atomizing nozzle 162 at its bottom, and a placement groove 163 is provided at the bottom of the silicone atomizing nozzle 162, with the silicone atomizing nozzle 162 placed inside the placement groove 163. By setting up the rubber belt 16, hose 161, silicone atomizing nozzle 162, and placement groove 163, when the rubber belt 16 is stretched, the silicone atomizing nozzle 162 is aligned with the construction site. Then, since the water supply mechanism delivers water through the hose 161, the water enters the silicone atomizing nozzle 162 through the hose 161, causing the silicone atomizing nozzle 162 to spray water mist to remove dust from the construction site.
[0029] Reference Figure 7 The water supply mechanism includes a water pump, a water tank, and a water pumping pipe. The water pumping pipe is connected to the water tank, and the other end of the water pumping pipe is connected to the water pump. The water pump is connected to the water supply pipe, and the water supply pipe is connected to the hose 161. The water supply pipe extends into the interior of the first winding wheel 13 and is rotatably connected to the first winding wheel 13, so that the water pump can transport the water in the water tank to the hose 161 through the water pumping pipe and the water supply pipe, thereby delivering water to the hose 161.
[0030] In this application, a first winding assembly is wound around the other side of the rubber belt 16. The first winding assembly includes a first winding wheel 13, a second synchronous wheel 12, a synchronous belt 11, and a first synchronous wheel 10. The shaft of the first winding wheel 13 is rotatably connected to a first support frame. The bottom of the first support frame is fixedly connected to the outer side of the surrounding plate 1. One side of the rubber belt 16 is wound around the surface of the first winding wheel 13. The shaft surface of the first winding wheel 13 is fixedly connected to the second synchronous wheel 12. The surface of the second synchronous wheel 12 is rotatably connected to the surface of the synchronous belt 11. One side of the synchronous belt 11 is rotatably connected to the first synchronous wheel 10. The interior of the first synchronous wheel 10 is fixedly connected to the shaft of the second winding wheel 13.
[0031] In this application, a sunshade net 15 is provided on the top surface of the rubber belt 16, and a second winding assembly is wound around the other side of the sunshade net 15. The first and second winding assemblies include a second winding wheel 6, a first gear 7, a second gear 8, and a first motor 9. One side of the sunshade net 15 is wound around the surface of the second winding wheel 6. A second support frame, which is fixedly connected to the outside of the surrounding plate 1, is rotatably connected to the rotating shaft surface of the second winding wheel 6. The conveying shaft of the second winding wheel 6 is fixedly connected to the first gear 7, and the surface of the first gear 7 meshes with the surface of the second gear 8. The interior of the second gear 8 is connected to the first motor 9. The output shaft is connected to the drive, and the surface of the first motor 9 is fixedly connected to the second support frame. Through the second take-up roller 6, the first gear 7, the second gear 8, the first motor 9, the first synchronous pulley 10, the synchronous belt 11, the second synchronous pulley 12, and the first take-up roller 13, the first motor 9 is started, which drives the second take-up roller 6 to rotate and wind the shade net 15 through the second gear 8 and the first gear 7. At the same time, the rotation of the second take-up roller 6 drives the first take-up roller 13 to rotate and wind the rubber belt 16 through the first synchronous pulley 10, the synchronous belt 11, and the second synchronous pulley 12, thus achieving the effect of winding up the shade net 15 and the rubber belt 16.
[0032] In this application, the shade net 15 and the rubber belt 16 are connected by a slider 17 fixedly installed on the enclosure 1 via the first guide wheel 14 and the second guide wheel 141. The shade net 15 and the rubber belt 16 are inserted into the interior of the limiting seat 21 via the slider 17. The limiting seat 21 is provided with a locking assembly for fixing the shade net 15 and the rubber belt 16. The locking assembly includes a fixing block 19 and a threaded rod 20. The bottom of the limiting seat 21 has a fixing groove 18, and the rubber belt 16 and the shade net 15 are inserted into the fixing groove 18. The top of the fixing groove 18 is provided with a fixing block 19, which presses the rubber belt 16 and the sunshade net 15. The top of the fixing block 19 is rotatably connected to the bottom of the threaded rod 20, and the threaded rod 20 is internally threadedly connected to the limiting seat 21. By setting the fixing block 19, the threaded rod 20 and the limiting seat 21, the rotation of the threaded rod 20 pushes the fixing block 19 downward, so that the fixing block 19 squeezes the sunshade net 15 and the rubber belt 16 located inside the fixing groove 18, thus completing the fixing of the rubber belt 16 and the sunshade net 15.
[0033] In this application, a fixing hole 22 is fixedly connected to the outer side of the limiting seat 21. A hook 23 is inserted into the inside of the fixing hole 22. A connecting plate 24 is fixedly connected to the other side of the hook 23. A pull rope 25 is fixedly connected to one side of the connecting plate 24. A positioning block 26 is slidably connected to the surface of the pull rope 25. The positioning block 26 provides a good positioning effect for the pull rope 25. The bottom of the positioning block 26 is fixedly installed on the enclosure 1 located in the third winding assembly. A third winding assembly for winding the pull rope 25 is provided on the other side of the pull rope 25. The third winding assembly is installed on another set of enclosure 1. The third winding assembly includes a third winding wheel 27, a rotating rod 28, a third gear 29, a fourth gear 291, and a second motor 30. The pull rope 25 is wound around the surface of the third winding wheel 27. The inside of the third winding wheel 27 is fixedly connected to the surface of the rotating rod 28. The two ends of the rotating rod 28 are rotatably connected. A third support frame is fixedly installed on the outside of the enclosure 1. One end of the rotating rod 28 is fixedly connected to the third gear 29. The surface of the third gear 29 meshes with the surface of the fourth gear 291. The inside of the fourth gear 291 is connected to the output shaft of the second motor 30. The first guide wheel 14 and the second guide wheel 141 on the enclosure 1 where the third winding assembly is located guide the pull rope 25. By setting the fixing hole 22 and the hook 23, the connection between the pull rope 25 and the limit seat 21 is realized. Through the pull rope 25, the third winding wheel 27, the rotating rod 28, the third gear 29, the fourth gear 291, and the second motor 30, the second motor 30 is started, which drives the rotating rod 28 to rotate through the fourth gear 291 and the third gear 29. The rotation of the rotating rod 28 drives the third winding wheel 27 to rotate and wind the pull rope 25, thereby achieving the winding of the pull rope 25.
[0034] The implementation principle of an environmentally friendly dust control device for civil construction in this application embodiment is as follows: by rotating the fixed plate 2, the mounting plate 3 is brought into contact with the ground, and then the threaded nail 4 is inserted into the ground through the mounting plate 3 to complete the fixed connection between the mounting plate 3 and the ground, thereby quickly installing the enclosure 1.
[0035] By linking the hook 23 on the first panel 1 with the connecting plate 24, the pull rope 25 is pulled to extend it. Then, the hook 23 is inserted into the fixing hole 22 on the opposite panel 1 for fixation. Next, the second motor 30 is started, and the power is transmitted through the fourth gear 291 and the third gear 29 to drive the rotating rod 28 to rotate. The rotating rod drives the third winding wheel 27 to rotate, winding up the pull rope 25.
[0036] Under the traction of the pull rope 25, the pulling force is transmitted through the hook 23 and the fixing hole 22, pulling the limiting seat 21 on the opposite side panel 1 to move. The movement of the limiting seat 21 causes the rubber belt 16 connected to it and the shade net 15 laid above to unfold synchronously, gradually extending and covering the entire space above the construction area.
[0037] Once deployed, the silicone atomizing nozzle 162 embedded inside the rubber belt 16 faces the construction area. When construction begins at a certain location, the water supply mechanism for that area can be activated to supply water to the hose 161. The water flows through the hose 161 to the silicone atomizing nozzle 162, spraying out a fine water mist that effectively suppresses dust dispersion and improves air quality.
[0038] Meanwhile, the shade net 15 can block strong direct sunlight, significantly reduce the ambient temperature at the construction site in summer, improve the comfort of workers, and reduce the risk of aging, overheating, or performance degradation of construction equipment caused by prolonged exposure to high temperature and strong light.
[0039] After construction is completed, simply manually pull the hook 23 out of the fixing hole 22 to release the tension of the pull rope. Then start the first motor 9, which drives the second take-up wheel 6 to rotate through the meshing transmission of the first gear 7 and the second gear 8, automatically winding up the shade net 15; at the same time, the second take-up wheel 6 drives the first take-up wheel 13 to rotate synchronously through the synchronous transmission of the first synchronous pulley 10, the synchronous belt 11 and the second synchronous pulley 12, winding up the rubber belt 16.
