Description

Technical Field

[0001] This utility model relates to the field of building dust removal technology, specifically a fog cannon dust suppression device for construction sites. Background Technology

[0002] Construction site work involves a series of production activities carried out within a planned site according to the engineering design. These activities encompass foundation excavation, main structure construction, wall building, water and electricity installation, and decoration. Equipment such as excavators, tower cranes, and concrete mixers are required. Excavation, transportation, and mixing processes generate significant amounts of dust. Fog cannons, through a high-pressure system, atomize water into fine mist, which combines with airborne dust particles, causing them to weigh down and settle, thus reducing the dust concentration on site. This protects the respiratory health of construction workers and reduces dust pollution to the surrounding environment. Currently, most fog cannon dust suppression devices rely on municipal clean water or manually transported water sources for replenishment, and cannot utilize natural rainwater resources. When it rains, the rainwater is directly lost and cannot be converted into a dust suppression water source, which means that the device needs to continuously consume external water sources. This not only does not conform to the concept of green construction, but also increases the operation and maintenance costs of the construction site.

[0003] Therefore, there is an urgent need to design a dust suppression device using fog cannons for construction sites to solve the above problems. Utility Model Content

[0017] Please see Figure 1-7 This utility model provides a technical solution: a fog cannon dust suppression device for construction sites, comprising: A water tank 1 with a top plate 11 has a water inlet 12 near its front end on the top plate 11; in this embodiment, a number of casters 5 are installed at the bottom of the water tank 1; the casters 5 under the water tank 1 facilitate the flexible movement of the device in the construction site, and can accurately operate on different dust sources such as building material stacking area and construction pouring area, greatly improving the targeting and efficiency of dust suppression, and effectively improving the air quality of the construction site. A dust suppression assembly 2 is disposed on the top plate 11 near its rear end; in this embodiment, the dust suppression assembly 2 includes: a mounting bracket 21 rotatably mounted on the top plate 11; a cannon barrel 22 rotatably connected to the mounting bracket 21; a fan 23 installed inside the cannon barrel 22 near one end thereof; an atomizer 24 installed inside the cannon barrel 22 near the other end thereof; a pump body 25 disposed in the water tank 1; and a conduit 26, one end of which is fixedly connected to the input end of the atomizer 24, and the other end of which passes through the mounting bracket 21 and extends into the water tank 1 and is fixedly connected to the output end of the pump body 25. 25 can spray water from the water tank 1 through the conduit 26 from the atomizer 24; an adjustment motor 27 is fixedly connected to the top plate 11; and a guide wheel 28 is fixedly connected to the drive end of the adjustment motor 27. The guide wheel 28 is connected to the mounting frame 21 through transmission. The dust suppression component 2 of this device supports multi-angle adjustment and mobile operation. It can drive the mounting frame 21 and the cannon 22 to rotate horizontally through the adjustment motor 27, and can also adjust the vertical angle by rotating the cannon 22 around the mounting frame 21. It can cover dust areas of different heights and ranges, avoiding the dust suppression blind spots of traditional fixed-angle fog cannons. A diversion assembly 3 is installed on the top surface of the top plate 11 and located above the inlet 12; and A filter assembly 4 is installed at the water inlet 12. In this embodiment, the filter assembly 4 includes: a bracket 41 fixedly connected to the lower surface of the top plate 11 and located below the water inlet 12; a filter frame 42 placed at the water inlet 12 and inserted into the bracket 41; and two pull blocks 43 fixedly connected to the left and right ends of the filter frame 42. The filter assembly 4 can pre-treat the injected clean water and the recovered rainwater. Specifically, the filter frame 42 can effectively block leaves, mud and other debris from entering the water tank 1, preventing debris from clogging the pump body 25, the conduit 26 or the atomizer 24, reducing downtime caused by equipment blockage. The filter frame 42 can be quickly removed and cleaned by the pull blocks 43. No professional tools are required for operation, reducing maintenance difficulty and frequency. This not only reduces equipment maintenance costs but also ensures long-term stable operation of the fog cannon and avoids affecting the progress of dust suppression operations due to equipment failure. Among them, the traffic diversion component 3 includes: A hollow guide seat 31 is fixedly connected to the top surface of the top plate 11 and located above the water inlet 12; A folding plate 33 is rotatably connected to the left and right side plates of the flow guide seat 31 via a support block 32. Two limiting sleeves 34 are symmetrically fixed on its lower surface. Two positioning seats 35 are symmetrically installed on the lower surface of the folding plate 33 and near its left and right sides. In this embodiment, a protective frame 316 for protecting the folding plate 33 when it is in the retracted state is fixedly connected to the front end face of the water tank 1. An extension frame 36 is movably connected to the side of the folding plate 33 away from the guide seat 31. Two insertion rods 37 that are adapted to the limiting sleeve 34 are fixedly connected to the extension frame 36. The extension frame 36 is connected to the folding plate 33 by inserting the insertion rods 37 into the limiting sleeve 34. Two mounting seats 38 are symmetrically mounted on the top plate 11 and located on the left and right sides of the flow guide seat 31, respectively. Each mounting seat 38 is hinged to a positioning seat 35 with a telescopic rod 39. Two protective plates 310 are symmetrically arranged on the top edges of the left and right side plates of the flow guide seat 31, and a baffle 311 is fixedly connected to both ends of the protective plate 310; Two guide frames 312 are fixedly connected to the left and right sides of the folding plate 33 and abut against the baffle 311; Two symmetrically arranged and fixedly connected pad frames 313 are respectively attached to the two protective plates 310. Each pad frame contains a fixed positioning magnet 314, which facilitates effective attraction of the iron extension frame 36 when retracted, preventing it from falling and increasing the stability of the entire device when retracted. A handle 315 is fixedly connected to the extension bracket 36; The device achieves efficient rainwater collection and recycling through the diversion component 3. When it rains, the unfolded folding plate 33 and extension frame 36 can form an expanded water collection area. Combined with the inclined guide of the guide seat 31, rainwater can be accurately collected to the inlet 12 and flow into the water tank 1 without the need to lay additional water collection pipes. The collected rainwater can be directly used as the water source for dust suppression by fog cannons after filtration, reducing the dependence on municipal clean water. Especially in the rainy season or at construction sites with water shortages, it can significantly reduce water consumption and indirectly reduce the water cost of construction sites, which is in line with the concept of green construction.

[0018] The working principle and usage of this utility model are as follows: First, when dust suppression operations are required, clean water can be injected into the water tank 1 through the water inlet 12 on the top plate 11. During the water inlet process, the guide seat 31 can guide the water flow to prevent overflow. Then, the device is started, and clean water is transported through the pump body 25 in the water tank 1 to the atomizer 24 at one end of the cannon barrel 22 via the conduit 26. The atomizer 24 atomizes the clean water into fine water mist. At the same time, the fan 23 at the other end of the cannon barrel 22 generates a high-speed airflow, which sprays the water mist from the cannon barrel 22 to form a fog curtain. The fog curtain adsorbs dust particles in the air to complete the dust suppression operation. If it is necessary to adjust the spray angle during the dust suppression operation, the adjustment motor 27 can be started, so that the guide wheel 28 drives the mounting frame 21 to rotate around the top plate 11, thereby driving the cannon barrel 22 to achieve horizontal angle adjustment. At the same time, the cannon barrel 22 can rotate around the mounting frame 21 to achieve vertical angle adjustment. In addition, the casters 5 under the water tank 1 facilitate the movement of the device within the construction site, effectively improving the flexibility of the construction operation. Secondly, when it rains, the drainage component 3 can be activated to recover rainwater. Specifically, the telescopic rod 39 on the mounting base 38 can be extended to push the folding plate 33 to rotate and unfold around the support block 32. When the guide frame 312 on one side of the folding plate 33 abuts against the baffle 311 on the guide seat 31 guard plate 310, the folding plate 33 reaches the preset tilt angle. At this time, the telescopic rod 39 is closed, and then the handle 315 of the extension frame 36 is pulled to make the extension frame 36 disengage from the positioning magnet 314 in the guard plate 310 pad frame 313. The insertion rod 37 of the extension frame 36 is aligned with the limiting sleeve 34 under the folding plate 33 and inserted. With the help of the tilting gravity of the folding plate 33, the extension frame 36 is stably installed. At this time, after the rainwater falls on the folding plate 33 and the extension frame 36, it flows along the slope to the hollow guide seat 31, and then converges along the slope of the guide seat 31 to the bottom inlet 12. Finally, it flows into the water tank 1 through the inlet 12, realizing the recovery of rainwater and the recycling of water resources. Finally, whether it is injected clean water or recycled rainwater, it will first pass through the filter assembly 4 when it enters the water inlet 12. The water flow first flows through the filter frame 42, which can block leaves, mud and other debris, preventing debris from entering the water tank 1 and clogging the pump body 25 or the atomizer 24. The clean water flows through the filter frame 42 into the water tank 1. When a lot of debris accumulates in the filter frame 42, the pull block 43 can be pulled to pull the filter frame 42 out of the water inlet 12 and the bracket 41 for cleaning. After cleaning, it can be inserted back into its original position to restore the filtration function and ensure the long-term stable operation of the device.

[0019] In summary, this utility model has the following advantages: This construction site dust suppression fog cannon system achieves efficient rainwater recovery and recycling through its diversion components and auxiliary structures. During rain, the unfolded folding panels and extension frames create an expanded water collection area. Combined with the inclined guide seat, rainwater is precisely collected at the inlet and flows into the water tank, eliminating the need for additional collection pipes. The recovered rainwater, after filtration, can be directly used as the water source for the fog cannon dust suppression, reducing reliance on municipal clean water. This is particularly beneficial during rainy seasons or at water-scarce construction sites, significantly reducing water consumption and indirectly lowering water costs, aligning with green construction principles. The filtration components and auxiliary structures pre-treat both the injected clean water and the recovered rainwater. The filter frame effectively prevents leaves, mud, and other debris from entering the water tank, avoiding blockages in the pump, pipes, or atomizers, and reducing equipment clogging. The system avoids shutdowns caused by blockages. The filter frame can be quickly removed for cleaning via a pull block, requiring no specialized tools and reducing maintenance difficulty and frequency. This not only reduces equipment repair costs but also ensures long-term stable operation of the mist cannon, preventing disruptions to dust suppression progress due to equipment malfunctions. Through the dust suppression components, their auxiliary structures, and casters, the device achieves multi-angle adjustment and mobility. It can rotate horizontally by adjusting the motor to drive the mounting frame and cannon barrel, and can also adjust the vertical angle by rotating the cannon barrel around the mounting frame. This allows it to cover dust areas of different heights and ranges, avoiding the blind spots of traditional fixed-angle mist cannons. Furthermore, the casters under the water tank facilitate flexible movement of the device within the construction site, enabling precise operation targeting different dust sources such as building material storage areas and construction pouring areas, significantly improving the targeting and efficiency of dust suppression and effectively improving air quality at construction sites.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
