Description

Technical Field

[0001] This utility model relates to the technical field of fogging dust suppression devices, and in particular to a high-pole fogging device for use on construction sites. Background Technology

[0002] To prevent the impact of construction on the atmospheric environment, a perimeter spray system has been installed to reduce dust from the construction site. If dust is severe during earthwork or site preparation, work must be suspended until dust emissions meet standards before resuming.

[0003] To reduce the impact of on-site operations on the atmospheric environment, daily measures such as increasing the height and density of the fencing and spraying are adopted to enhance the effect of blocking and reducing dust, thereby reducing the idle labor costs caused by work stoppages, accelerating the construction progress, and achieving good results in environmental protection.

[0004] However, some problems have been found in the actual use of the above measures:

[0005] 1. The spray nozzles on the fence are prone to clogging due to scale buildup, requiring routine maintenance. However, because the spray pipes are too high, routine maintenance requires the use of a ladder truck, which involves working at heights and incurs high manpower and machinery costs.

[0006] 2. Spray head series control: If one spray head or section of pipe becomes clogged with scale, the entire spray system must stop working, causing dust to float in the construction site and the dust concentration to exceed the standard, requiring work to be stopped for rectification.

[0007] Chinese patent CN211676879U discloses a fogging dust suppression device for construction sites. It includes a baffle with multiple uprights fixed to its back. These uprights are connected by two horizontal bars. A rotating sleeve is hinged to the middle of the upper horizontal bar, and a rotating tube is fixed inside the rotating sleeve. The rotating tube is parallel to the uprights, and a nozzle is fixed to its upper end. A concentric rotating sleeve is rotatably connected to the lower horizontal bar. Fixing plates are fixed to both sides of the rotating tube on the front of the rotating sleeve, contacting the rotating tube. The lower ends of the uprights are connected by a horizontal water pipe. A metal flexible hose is threaded and sealed to the left end of the water pipe, and a connecting flexible hose is fixed and sealed to the water pipe. The flexible hose is connected to the lower end of the rotating tube via a quick connector.

[0008] The construction site's fogging dust suppression device is constructed with multiple integrated baffles that are easy to install. The rotating pipe allows the nozzles to be positioned below for easy maintenance. The water pipes and flexible hoses connected to the rotating pipe are located on the back side of the lower part of the baffles, making maintenance even more convenient.

[0009] Although the fogging dust suppression device at the construction site can effectively block and reduce dust, and is also easy to maintain, it cannot be used to repair a single nozzle or a section of pipe. If a nozzle becomes clogged, the entire spraying system must be shut down, leading to excessive dust concentration and impacting the atmospheric environment. Furthermore, routine maintenance and repair of the fogging dust suppression device requires working at heights, still necessitating the investment of manpower and machinery, which increases maintenance costs and inspection risks. Summary of the Invention

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0037] The inventors discovered that existing construction site fogging dust suppression devices cannot perform maintenance on a single nozzle or a section of pipe. If a nozzle becomes clogged and needs repair, the entire spraying system must be shut down, leading to excessive dust concentration and impacting the atmospheric environment. Furthermore, routine maintenance and repair of the fogging dust suppression device requires working at heights, still necessitating the investment of manpower and machinery, which increases maintenance costs and inspection risks.

[0038] Based on the above findings, this application proposes a high-pole fogging device for construction sites, which can reduce maintenance costs and inspection risks, while allowing for segmented maintenance and upkeep, avoiding large-scale downtime due to maintenance, and improving work efficiency. Example

[0039] See Figures 1-8 This application discloses a high-pole fogging device for construction sites, including a baffle 1. A first upright 2 located on the side and a plurality of second uprights 3 located in the middle are connected to the back of the baffle 1. A sliding structure is connected to the side of the first upright 2 facing the second upright 3. Sliding structures are also connected to the side of the second upright 3 facing the first upright 2 and the side facing the adjacent second upright 3. A first connecting member 4 is connected between the opposing sliding structures. A spraying structure is connected to the first connecting member 4.

[0040] The spray structure includes a spray pipe 12 and a nozzle 13. The spray pipe 12 is connected to a water supply branch pipe 14, the water supply branch pipe 14 is connected to a water supply main pipe 15, and a shut-off valve 16 is provided between the water supply main pipe 15 and the water supply branch pipe 14.

[0041] The first connector 4 is made of 8mm steel wire rope and is connected to a spray pipe 12 with a nozzle 13.

[0042] The water supply main pipe 15 is set below, and the spray structure with 10mm diameter water supply branch pipes 14 connected in parallel on the water supply main pipe 15 between each span of the keel is adopted. The parallel connection of each span solves the problem of the entire spray pipeline being shut down due to maintenance or blockage in one place. It ensures the blocking effect of dust floating on the field and improves the on-site operation time.

[0043] Traditional fog walls typically have a maximum height of 6 meters. The first upright (2) and second upright (3) are made of lightweight materials, increasing the fog wall's installation height to meet the requirements of a 10-meter multi-stage spray system. The first upright (2) and second upright (3) are connected to the main keel of the baffle (1). The main keel of the baffle (1) is no less than 120*120*4mm galvanized square steel, and the foundation is no less than 500*500*1000mm.

[0044] The sliding structure includes a slide groove 5 and a pulley component. The pulley component matches the slide groove 5. A second connector 6 is connected between the bottom of the first upright 2 and the pulley component. A second connector 6 is also connected between the bottom of the second upright 3 and the pulley component. The second connector 6 is used to extend or shorten the distance between the pulley components.

[0045] The chute 5 is made of 100*100*4mm thick square steel, and the second connector 6 is made of 6mm steel wire rope. This reduces the construction difficulty of the original square steel fog wall frame and reduces the self-weight of the fog wall frame. The mutual pulling of the steel wire ropes also helps to stabilize the overall frame.

[0046] The top of both the first upright 2 and the second upright 3 is connected to a guide wheel 7. The guide wheel 7 is connected to the pulley component by a third connector 8, which is used to pull the pulley component up and down.

[0047] like Figure 3 As shown, the pulley component includes a first pulley 9 and two second pulleys 10, forming a three-stage spray system. The first pulley 9 is located above the second pulleys 10, and a second connector 6 is connected between the first pulley 9 and the second pulleys 10. A second connector 6 is also connected between two adjacent second pulleys 10.

[0048] The first pulley 9 is connected to the third connector 8, the bottom of the first upright 2 is connected to the second pulley 10 by the second connector 6, and the bottom of the second upright 3 is connected to the second pulley 10 by the second connector 6.

[0049] The first pulley 9 and the second pulley 10 are both equipped with a slider, a support rod, and a first hanging ring. The slider is slidably connected to the slide groove 5. One end of the support rod is connected to the slide groove 5, and the other end is connected to the first hanging ring. The first hanging ring is used to connect the first connecting piece 4.

[0050] The support rod of the first pulley 9 is provided with a second hanging ring for connecting the third connecting member 8 near the slide groove 5.

[0051] The second connecting piece 6 connecting the first pulley 9 and the second pulley 10, and the second connecting piece 6 connecting two adjacent second pulleys 10, form a taut state during use, while allowing the first pulley 9 and the second pulley 10 to descend freely, so that the highest point nozzle 13 can be lowered to 4m above the ground, thus realizing a simple support ladder that meets daily maintenance needs and can be removed during maintenance.

[0052] The third connector 8 uses a 6mm steel wire rope, and the guide wheel 7 pulls the first pulley 9 and the second pulley 10 to rise and fall through the third connector 8.

[0053] The first upright 2 and the second upright 3 are connected to a limiting block 11 for restricting the sliding structure. The limiting block 11 is respectively located at the top and bottom of the sliding structure.

[0054] The main water supply pipe 15 uses a DN25 PE pipe, and the branch water supply pipe 14 uses a DN10 PE hose specifically for spraying. Each pressurizer drives no more than 150-170 sprinkler heads 13. Example

[0055] like Figure 1 and Figure 2 As shown, the difference from Embodiment 1 is that the pulley component includes a first pulley 9 and four second pulleys 10 to form a five-stage spray system, which further increases the height of the fog wall and improves the spraying effect. When maintenance is required, the first pulley 9 and the second pulleys 10 can be lowered so that the end is no more than 4m above the ground, and only a simple support ladder is needed for maintenance.

[0056] The specific usage process of this utility model:

[0057] In normal working condition, the guide wheel 7 pulls the first pulley 9 and the second pulley 10 to the position of the limiting block 11 at the top of the first upright 2 and the second upright 3, so that the third connecting piece 8, the second connecting piece 6 and the first connecting piece 4 are tightened respectively, the spray structure reaches the corresponding position, the pressurizer is turned on, and the spray structure starts to work.

[0058] When the nozzle 13 is clogged and requires repair or routine maintenance, it can be controlled in sections. Open the shut-off valve 16 between the main water supply pipe 15 and the branch water supply pipe 14, loosen the third connector 8, and let the first pulley 9 and the second pulley 10 between a set of first uprights 2 and second uprights 3, or between two adjacent second uprights 3, fall freely. Let the second pulley 10 fall to the position of the limit block 11 at the bottom of the first uprights 2 and second uprights 3. The highest point of the spray head can be lowered to 4m above the ground, realizing a simple support ladder that meets the needs of routine maintenance. It can be removed during maintenance.

[0059] This solved the problem of long spray pipes being shut down due to maintenance or blockage, ensuring the effective prevention of dust floating off the site and improving on-site operation time.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
