Description

Technical Field

[0001] This utility model relates to the field of construction site technology, and in particular to a dust-reducing enclosure for construction sites that is easy to assemble. Background Technology

[0002] Construction sites generate significant amounts of dust, polluting the air, harming health, and impacting the surrounding ecosystem. Dust-reducing barriers can effectively suppress dust dispersion, improve air quality, and protect the health of construction workers and nearby residents. Furthermore, this aligns with civilized construction practices, enhances the company's image, complies with environmental regulations, avoids penalties, and also provides noise isolation to some extent, facilitating site management.

[0003] In existing technologies, the use of dust suppression barriers is mostly done as a single unit or with a long installation time, which is time-consuming and difficult to assemble. For example, the technical solution provided by Chinese Utility Model Patent Publication No. CN221703386U describes a dust suppression barrier installation process that is often lengthy and complex due to its large size, especially the need for ground nails for stabilization. However, these ground nails often lack effective protection during transportation, which can lead to several problems. First, the ground nails may be damaged, deformed, or even broken due to collisions or friction during transport, thus affecting their effectiveness during installation.

[0004] Secondly, the exposed tips of the ground stakes pose a safety hazard, potentially causing cuts or other injuries to personnel during loading, unloading, or handling. Furthermore, the lack of protective devices on the ground stakes can lead to rust or damage to their surface, thereby reducing their corrosion resistance and service life. Therefore, we propose an easily assembled dust-reducing barrier for construction sites. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a dust suppression barrier that is easy to assemble for use on construction sites, so as to solve the technical problems that the current dust suppression barriers are inconvenient to assemble during installation and cannot provide better protection for ground nails.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a dust suppression enclosure for easy assembly at a construction site, with two columns having a hollow structure, and a snap-fit ​​component provided inside the two columns, and a dust suppression component snapped between the two columns through the snap-fit ​​component;

[0007] Both of the two columns have ground nails on one side of their bottom, and top plates are installed on the top of the ground nails. Both of the two columns have fixing components on one side for fixing the position of the ground nails. Both of the two columns have outer shells on one side for protecting the ground nails, and the ground nails slide in the vertical direction of the outer shells.

[0008] Below the snap-fit ​​assembly is a drive assembly located on the inner wall of the column. A straight groove is provided on one side below the column. A baffle for blocking the ground nail from falling is slidably connected inside the straight groove, and the drive assembly adjusts the position of the baffle during transmission.

[0009] Preferably, the dust suppression assembly includes a dust suppression screen and nozzles. A dust suppression screen is fixedly connected between the two columns. Support plates are fixedly connected to both ends and the front and rear sides of the dust suppression screen. A water pump and a water tank are fixedly connected to the top of the two support plates, respectively. Nozzles are provided on both ends and the front and rear sides of the dust suppression screen. The inlet of the water pump is connected to the water tank, and the outlet of the water pump is connected to the nozzles.

[0010] Preferably, the fixing component includes a U-shaped plate, and a U-shaped plate is fixedly connected to one side of the bottom of each of the two columns. One end of the U-shaped plate is threadedly connected to a clamping bolt, and the inside of the U-shaped plate is slidably connected to a ground nail.

[0011] Preferably, the snap-fit ​​assembly includes a bidirectional threaded rod and a pin. Both of the columns are provided with a bidirectional threaded rod inside. The top of the bidirectional threaded rod is threadedly connected to a limiting plate, and a pin is fixedly connected to the top of one side of the limiting plate.

[0012] Preferably, the drive assembly includes a worm, a turbine, and a spur gear. The bottom of the two columns is provided with a worm, one side of which meshes with the turbine. The bottom of the turbine is fixedly connected with a spur gear, one side of which meshes with a rack. A bearing seat is provided in the middle of the bidirectional threaded rod. The bottom of the bidirectional threaded rod is fixedly connected to the top of the turbine. A handwheel is fixedly connected to one end of the worm.

[0013] Preferably, a fixing block is fixedly connected to one side of the dust suppression mesh plate, and a slot is provided at one end of the fixing block. A limiting groove for limiting the limiting plate is provided on one side of the top of the two columns, and a slot is provided on the top.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model improves the existing dust suppression barrier structure at construction sites by incorporating a driving component, a fixing component, and a snap-fit ​​component. The driving component works in conjunction with the snap-fit ​​component, thereby moving the barrier to limit the ground nails and better secure the dustproof mesh. This makes the assembly of the dust suppression barrier more convenient, reduces working time, and facilitates unified management. Through combined linkage, it improves construction efficiency and allows for rapid assembly and installation for use.

[0016] 2. In this utility model, the handwheel drives the worm gear and turbine to rotate, thereby driving the spur gear and rack to move, which in turn drives the baffle to move left and right. When the fence is installed, the rotating device drives the baffle to move, and at the same time the pin is inserted into the slot to fix the dustproof netting. Then, the pile driver screws the ground nails into the ground. By setting the baffle, the ground nails are prevented from loosening during the transportation of the fence, thus preventing injury to personnel and also preventing damage to the ground nails to a certain extent.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] A dust-control enclosure for easy assembly at construction sites, see [link / reference]. Figures 1 to 6The device includes two hollow columns 1, each with a snap-fit ​​assembly inside. A dust-reducing assembly is snapped between the two columns 1 via the snap-fit ​​assembly. A ground nail 11 is installed on one side of the bottom of each column 1, with a top plate mounted on top of each nail 11. A fixing assembly for fixing the position of the nail 11 is installed on one side of each column 1, and a housing 13 for protecting the nail 11 is installed on one side of each column 1, with the nail 11 sliding vertically along the housing 13. A drive assembly is located below the snap-fit ​​assembly on the inner wall of the column 1. A straight groove is formed on one side of the column 1 below, with a baffle 14 slidably connected inside the groove to prevent the nail 11 from falling. The drive assembly adjusts the position of the baffle 14 during transmission. This utility model improves the existing dust suppression enclosure structure by setting a snap-fit ​​component to fix the dust suppression net plate 2 when using the device, and adjusts the position of the baffle 14 during transmission through the drive component, thereby facilitating the drilling of the ground nail 11 into the ground.

[0026] Specifically, the dust suppression assembly includes a dust suppression mesh plate 2 and nozzles 3. The dust suppression mesh plate 2 is fixedly connected between two columns 1. Support plates 8 are fixedly connected to both ends and the front and rear sides of the dust suppression mesh plate 2. A water pump 9 and a water tank 10 are fixedly connected to the tops of the two support plates 8, respectively. Nozzles 3 are provided on both ends and the front and rear sides of the dust suppression mesh plate 2. The inlet of the water pump 9 is connected to the water tank 10, and the outlet of the water pump 9 is connected to the nozzles 3. In this invention, multiple mesh holes are opened on the dust suppression mesh plate 1, which not only prevents wind and suppresses dust but also allows for ventilation, effectively improving wind resistance. Furthermore, the nozzles 3, supplied with water by the water pump 9, spray water, further enhancing the dust suppression effect. It should be noted that the dust suppression mesh plate has through holes corresponding to the water inlet pipe on opposite sides, and the water outlet pipe is also located inside the dust suppression mesh plate to transport liquid to the nozzles 3.

[0027] Furthermore, the fixing component includes a U-shaped plate 12. A U-shaped plate 12 is fixedly connected to one side of the bottom of each of the two columns 1. One end of the U-shaped plate 12 is threadedly connected to a clamping bolt, and the interior of the U-shaped plate 12 is slidably connected to the ground nail 11. This invention, by providing the U-shaped plate 12 and clamping bolt, allows the ground nail 11 to be driven into the ground after the device is fixed in position by loosening the clamping bolt and then tightening the clamping bolt to secure the U-shaped plate 12. This further fixes the ground nail 11, preventing it from loosening and causing danger during use.

[0028] It is worth noting that the snap-fit ​​assembly includes a bidirectional threaded rod 15 and a pin 17. Both columns 1 have a bidirectional threaded rod 15 inside. The top of the bidirectional threaded rod 15 is threadedly connected to a limiting plate 16, and the pin 17 is fixedly connected to the top of one side of the limiting plate 16. During use, the drive assembly rotates the bidirectional threaded rod 15, thereby causing the limiting plate 16 to move up and down, which in turn moves the pin 17, thus fixing the fixing block 7 and the dust suppression mesh plate 2. This improves the stability of the device and also provides safety assurance.

[0029] It is worth mentioning that the drive assembly includes a worm gear 18, a turbine gear 19, and a spur gear 20. The worm gear 18 is located at the bottom of the two columns 1, and one side of the worm gear 18 meshes with the turbine gear 19. The bottom of the turbine gear 19 is fixedly connected to the spur gear 20, and one side of the spur gear 20 meshes with the rack 21. A bearing seat 22 is located in the middle of the double-threaded rod 15, and the bottom of the double-threaded rod 15 is fixedly connected to the top of the turbine gear 19. A handwheel 4 is fixedly connected to one end of the worm gear 18. The handwheel 4 drives the rotation of the worm gear 18 and the turbine gear 19, thereby driving the rotation of the spur gear 20 and the movement of the rack 21, thus realizing the movement of the baffle 14. When the device is not in use, it effectively protects the ground nail 11, preventing the ground nail 11 from falling or moving. At the same time, the outer shell 13 is provided to further protect the ground nail 11.

[0030] It is worth noting that a fixing block 7 is fixedly connected to one side of the dust suppression mesh plate 2, and a slot is provided at one end of the fixing block 7. A limiting groove 5 for limiting the limiting plate 16 is provided on one side of the top of the two columns 1, and a slot 6 is provided on the top, which is beneficial for fixing the dust suppression mesh plate 2.

[0031] It should be noted that in this utility model, the baffle does not enter the straight groove when the column and the dust suppression mesh are not fully engaged, therefore, the ground nail cannot move downwards.

[0032] Working principle: When using this utility model, first determine the position of the device, then drive the bidirectional threaded rod 15 to rotate through the drive component, thereby moving the limiting plate 16 inside the limiting groove 5, which in turn moves the pin 17. The pin 17 is inserted into the fixing block 7 to fix the dust suppression mesh plate 2. At the same time, by rotating the handwheel 4, the worm gear 18 is driven, which in turn drives the turbine 19 and the spur gear 20 to rotate, which in turn drives the rack 21 to move left and right, so that the baffle 14 can move left and right, making it easier for the ground nail 11 to drill into the ground and further fix the device, providing a favorable guarantee when using the device.

[0033] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
