Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for construction sites, and in particular to a dust suppression device for the periphery of a construction site. Background Technology

[0002] Existing technologies for dust control at construction sites mainly include two methods;

[0003] One method is to use fog cannons. In key construction areas, when large amounts of dust and smoke are generated, fog cannons are used to control the dust. The principle is that the application of dust suppression fog cannons on construction sites mainly achieves efficient dust suppression through high-pressure atomization technology. Its core principle is to convert water into micron-sized water mist particles, which are then sprayed remotely by a fan to cover the dusty area, causing the water mist to combine with the dust and settle. For example, there is a Chinese utility model patent, publication number CN219482092U, entitled "A Dust Suppression Device for Civil Engineering." However, the use of fog cannons is limited to the interior of the construction site, and is not suitable for dust suppression around the building area, due to reasons such as their large size and the fact that the effect of the fog cannons could easily affect passersby.

[0004] For the area surrounding the construction site, another option, which is the only one, is to install sprinklers on the guardrails. However, this requires a large amount of water, and the increased atomization of the air results in long pipelines, which is not conducive to installation. Utility Model Content

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. It should be noted that, for ease of description, in this application, "left side" is referred to as "first end", "right side" as "second end", "upper side" as "first end", and "lower side" as "second end" in the current view. The purpose of such description is to clearly express the technical solution and should not be construed as an improper limitation of the technical solution of this application.

[0058] This invention aims to address the technical problem of the lack of easily installable and configurable dust suppression spraying facilities in the periphery of construction sites, and provides a dust suppression device for the periphery of construction sites. In one specific embodiment, please refer to... Figure 1 , 2 As shown, specifically for stable and rapid installation, a connecting body 101 is used. The connecting body 101 is fixedly connected to a mounting bracket assembly. The mounting bracket assembly 10 can be detachably installed on the fence to ensure basic installation.

[0059] In terms of pipeline configuration, a locking area is formed on the connecting body 101, and an intermediate spray body 110 can be supported by the locking area and locked onto the connecting body 101 by a set of fasteners 200.

[0060] During the initial installation, the side spray bodies 120 can be welded to both sides of the central spray body 110. After the fasteners 200 are screwed in, there is no need to cut the side spray bodies 120.

[0061] Atomizing component is connected to the side spray body 120. The atomizing component can deliver atomized spray water to the side spray body 120 and the middle spray body 110. The middle spray body 110 and the side spray body 120 are provided with nozzle assembly 130. The output spray direction of the nozzle assembly 130 is towards the first direction.

[0062] In this technical solution, the connecting body 101 is used to securely install the intermediate spray body 110, and then the side spray body 120 is connected. This increases the pressure-bearing capacity, provides stable spray atomized water, and has a simple configuration. Multiple sets of this dust suppression equipment can be arranged along the periphery to increase the dust suppression effect.

[0063] In one specific embodiment, please refer to Figure 1 , 3 As shown in Figure 4, the connecting body 101 includes a fixed back plate 11 and two sets of locking members 12; the two sets of locking members 12 are arranged in parallel and are perpendicularly connected to the fixed back plate 11; a first preset distance is formed between the two sets of locking members 12; a second preset distance is formed between the locking members 12 and the fixed back plate 11.

[0064] The first preset spacing is used to ensure the configuration space of the intermediate spray body 110, and the second preset spacing is used to ensure the adjustment space of the fastener 200.

[0065] In one specific embodiment, please refer to Figure 1 As shown: The mounting bracket assembly 10 includes: a connecting frame 13, which is connected to the side of the fixed back plate 11 away from the side where the locking member 12 is located; two sets of support plates 14 are connected below the connecting frame 13, and the two sets of support plates 14 are fixedly connected by staggered connecting ribs 15; a connecting ear 16 is fixedly connected to the side of the support plate 14, and a connecting thread hole 17 is provided on the connecting ear 16.

[0066] In one specific embodiment, please refer to Figure 1 , 3As shown in Figure 4: Each set of locking members 12 is constructed with a locking arc-shaped portion 121; the locking arc-shaped portion 121 is a semi-circular arc; the locking member 12 has a low end 122, which is disposed close to the fixed back plate 11; the locking member 12 has a high end 123, which is disposed away from the fixed back plate 11; the distance from the high end 123 to the bottom edge of the locking member 12 is greater than the distance from the low end 122 to the bottom edge of the locking member 12.

[0067] The main body of the intermediate tube 111 is fitted onto a semi-circular arc, and its two ends are equipped with welding joints 112.

[0068] External threads are provided on the outer diameter of both sides of the intermediate tube body 111;

[0069] Fastener 200 has two sets of locking screws. The locking nut is screwed onto the intermediate tube body 111 before welding alignment at the welding joint 112. The intermediate tube body 111 and one side of the locking part 12 can be locked with fastener 200 first, and then the side spray body 120 can be welded (this is the first configuration). The fastener 200 can be adjusted to achieve contact fastening later. Of course, the connection between fastener 200 and intermediate tube body 111 can also be prefabricated.

[0070] In one specific embodiment, please refer to Figure 1 As shown: The nozzle assembly 130 includes: a spray pipe 131, and the spray pipe 131 is connected to the radial direction of the intermediate pipe body 111 and the radial direction of the side spray body 120; a curved nozzle 133 is connected to the end of the spray pipe 131; an operating ball valve 132 is provided on the spray pipe 131 for adjusting the pressure and spray volume.

[0071] In one specific embodiment, please refer to Figure 1 As shown: The atomizing component includes: a Y-shaped connector 301, one end of which has an output connecting pipe 301a; the output connecting pipe 301a is connected to one end of the side spray body 120 through a delivery pipe 302; the other end of the Y-shaped connector 301 has a first Y-side connection port 301b and a second Y-side connection port 301c; the first Y-side connection port 301b is used to connect non-purified air, the pressure of which is 0.35MPa, and the non-purified air can be provided by using a compressor and a small air canister. The pressure is less than the pressure vessel technical standard and it is not a pressure vessel.

[0072] The second Y-side connection port 301c is used to connect the spray water. The pressure of the spray water is 0.45MPa, which is the pressure of a public water source. The actual pressure may be slightly lower, but it is guaranteed that the water pressure is greater than the air pressure by a pressure difference of 0.1-0.15MPa. This allows the premixing of the spray water to produce atomized spray in the Y-type connector 301. Alternatively, to further stabilize the atomization component, a constricted channel 134 can be formed inside the curved nozzle 133, or an internal channel structure with a pressurization type, such as a venturi tube, can be used.

[0073] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
