AI Technical Summary
Existing dust suppression devices for construction sites require manual, repeated swinging of the ventilation duct, which is labor-intensive. Furthermore, the fixed height of the ventilation duct makes it easy for debris on the construction site to obstruct the dust suppression process, resulting in incomplete dust suppression.
The system employs a lifting and swinging mechanism and a spray dust suppression mechanism. The automatic swinging system consists of an electric telescopic rod, a geared motor, an intermittent gear plate, gears, a rotating shaft, and a spiral spring. Combined with a high-pressure water pump and a powerful fan, it enables the ventilation duct to automatically swing repeatedly and adjust its height.
This reduces the intensity of manual labor and ensures that the sprayed water can cover all areas of the construction site, achieving a comprehensive dust reduction effect.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a dust suppression device for building construction. Background Technology
[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of buildings, or the process of turning the lines on design drawings into physical objects at a designated location. This includes foundation construction, main structure construction, roofing construction, and decoration construction. The site of these construction operations is called the "construction site" or "construction work site." Construction workers utilize various building materials and machinery to carry out production activities within a specific space and time according to detailed design blueprints, aiming to build various architectural products. Construction is a technically complex process involving the supply of hundreds or even thousands of materials and the operation of various mechanical equipment. On construction sites, it is difficult to avoid airborne dust. When dust concentrations are high, it pollutes the environment and can enter the bodies of construction workers through respiration, causing harm. Therefore, dust suppression devices are necessary in construction.
[0003] Currently, the dust suppression devices used at construction sites are mainly fog cannons. Although fog cannons can effectively spray and suppress dust at construction sites, in order to achieve comprehensive dust suppression, workers often need to repeatedly swing the nozzle to change the direction of the spray. This manual swinging of the nozzle results in high labor intensity for the workers. In addition, because the height of the nozzle on the fog cannon is fixed, it is easy for debris on the construction site to block the water spray, making the dust suppression incomplete. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a dust suppression device for construction sites that can automatically and repeatedly swing to achieve dust suppression by spraying, and can be conveniently adjusted according to the actual height of the ventilation duct, so as to achieve more thorough dust suppression.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a construction dust suppression device, including a movable base, a lifting and swinging mechanism installed on one side of the upper end of the movable base, and a spray dust suppression mechanism installed on one side of the lifting and swinging mechanism on the movable base. The lifting and swinging mechanism includes electric telescopic rods symmetrically installed on both sides of the upper end of the movable base, a mounting plate jointly installed on the telescopic parts of the two electric telescopic rods, a reduction motor installed on one side of the bottom end of the mounting plate, an intermittent gear plate installed on the power output end of the reduction motor, a rotating shaft installed on the mounting plate on one side of the intermittent gear plate, a gear installed on the rotating shaft and meshing with the teeth of the intermittent gear plate, a mounting sleeve installed on the bottom end of the mounting plate on the outside of the rotating shaft, and a spiral spring installed on the inner wall of the mounting sleeve between the rotating shaft and the rotating shaft. The spray dust suppression mechanism includes a U-shaped support connected to the top end of the rotating shaft and a duct installed inside the support.
[0006] Furthermore, the dust suppression spraying mechanism also includes a powerful fan installed at the air inlet of the air duct, a water spray ring installed at the air outlet of the air duct, a water tank installed on one side of the upper end of the movable base, and a high-pressure water pump installed on one side of the top of the water tank.
[0007] By adopting the above technical solution, when spraying water to suppress dust at a construction site, the water in the water tank can be pumped to the spray ring under the action of the high-pressure water pump, and the water sprayed out by the spray ring will be blown to the dust suppression position under the action of the powerful fan.
[0008] Furthermore, the inlet of the high-pressure water pump is connected to the water tank via a pipe, and the outlet of the high-pressure water pump is connected to the spray ring via a flexible hose.
[0009] By adopting the above technical solution, it can be ensured that the high-pressure water pump delivers water normally into the spray pipe.
[0010] Furthermore, the telescopic part of the electric telescopic rod is bolted to the mounting plate, the power output shaft of the geared motor is keyed to the intermittent gear plate, the gear is welded to the rotating shaft, and the rotating shaft passes through the mounting plate.
[0011] By adopting the above technical solution, the intermittent gear disk and the gear mesh intermittently, thereby realizing the intermittent rotation of the rotating shaft.
[0012] Furthermore, the rotating shaft is welded to one end of the spiral spring on the lower side of the mounting plate, and the other end of the spiral spring is welded to the inner wall of the mounting sleeve. The spiral springs are evenly distributed from top to bottom on the mounting sleeve.
[0013] By adopting the above technical solution, when the teeth on the intermittent toothed disc separate from the gear, the rotating shaft will be reset under the action of the spiral spring, thereby cooperating with the prying motion on the intermittent toothed disc to realize the repeated swinging of the air duct during dust suppression spraying.
[0014] Furthermore, the rotating shaft is bolted to the bracket, and the rotating shaft is rotatably connected to the mounting plate.
[0015] By adopting the above technical solution, the convenient rotation of the rotating shaft relative to the mounting plate can be ensured.
[0016] Furthermore, a battery is installed on one side of the water tank on the mobile base, and a push handle is welded on both sides of the battery on the mobile base, with an operation panel installed on the upper end of the push handle.
[0017] By adopting the above technical solution, the operation panel mainly controls the opening and closing of the geared motor, the high-pressure water pump, the powerful fan and the electric telescopic rod by controlling the on and off of the control circuit.
[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0019] To address the current problem that dust suppression devices primarily used in construction sites are mist cannons, while effective for dust control, require manual manipulation of the spray nozzles to change the spray direction. This manual manipulation is labor-intensive, and the fixed height of the nozzles makes them susceptible to obstruction by debris, resulting in incomplete dust suppression. This invention addresses this issue by installing a lifting and swinging mechanism at the bottom of the spray nozzle. This allows for electrically driven repeated swinging of the nozzle, effectively reducing manual labor. Furthermore, adjusting the nozzle height prevents obstruction by debris, ensuring thorough dust suppression. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0028] Example 1, such as Figures 1-3As shown, a construction dust suppression device in this embodiment includes a movable base 4.

The mechanism also includes a U-shaped support 603 connected to the top of the rotating shaft 506 and a duct 605 installed inside the support 603. The intermittent gear 504 meshes with the gear 505 intermittently, which can realize the intermittent rotation of the rotating shaft 506. When the teeth on the intermittent gear 504 separate from the gear 505, the rotating shaft 506 will be reset under the action of the spiral spring 508, thereby cooperating with the prying on the intermittent gear 504 to realize the repeated swinging of the duct 605 during dust suppression spraying.
[0029] like Figures 1-3 As shown, in this embodiment, the dust suppression spraying mechanism 6 also includes a powerful fan 604 installed at the air inlet of the air duct 605, a water spray ring 606 installed at the air outlet of the air duct 605, a water tank 601 installed on one side of the upper end of the movable base 4, and a high-pressure water pump 602 installed on one side of the top of the water tank 601. When spraying dust to the construction site, the water in the water tank 601 can be pumped to the water spray ring 606 under the action of the high-pressure water pump 602. The water sprayed out by the water spray ring 606 will be blown to the dust suppression position under the action of the powerful fan 604.
[0030] like Figures 1-3 As shown, in this embodiment, the inlet of the high-pressure water pump 602 is connected to the water tank 601 through a pipe, and the outlet of the high-pressure water pump 602 is connected to the spray ring 606 through a hose, which can ensure that the high-pressure water pump 602 delivers water normally into the spray pipe.
[0031] like Figures 1-3As shown, in this embodiment, the telescopic part of the electric telescopic rod 501 is bolted to the mounting plate 507, the power output shaft of the geared motor 502 is keyed to the intermittent gear plate 504, the gear 505 is welded to the rotating shaft 506, and the rotating shaft 506 passes through the mounting plate 507. The part of the rotating shaft 506 located on the lower side of the mounting plate 507 is welded to one end of the spiral spring 508, and the other end of the spiral spring 508 is welded to the inner wall of the mounting sleeve 503. The spiral springs 508 are evenly distributed from top to bottom in the mounting sleeve 503. The rotating shaft 506 is bolted to the bracket 603, and the rotating shaft 506 is rotatably connected to the mounting plate 507, which can ensure convenient rotation of the rotating shaft 506 relative to the mounting plate 507.
[0032] like Figures 1-3 As shown, in this embodiment, a battery 3 is also installed on the mobile base 4 on one side of the water tank 601. A push handle 2 is also welded on both sides of the battery 3 on the mobile base 4. An operation panel 1 is installed on the upper end of the push handle 2. The operation panel 1 mainly controls the opening and closing of the geared motor 502, the high-pressure water pump 602, the powerful fan 604 and the electric telescopic rod 501 by controlling the on and off of the control circuit.
[0033] The specific implementation process of this embodiment is as follows: When it is necessary to spray dust suppression at a construction site, firstly, move the device to the usage position and position the air duct 605 directly facing the dust suppression area. Then, under the action of the electric telescopic rod 501, adjust the air duct 605 to a suitable height, and start the high-pressure water pump 602 and the powerful fan 604. Under the action of the high-pressure water pump 602, the water in the water tank 601 is pumped to the spray ring 606, so that the water sprayed by the spray ring 606 is blown to the dust suppression position under the action of the powerful fan 604, thereby achieving dust suppression at the construction site. The dust suppression spraying system works by rotating an intermittent geared disc 504 under the action of a reduction motor 502. During rotation, the intermittent geared disc 504 intermittently meshes with a gear 505. When the intermittent geared disc 504 is meshing with the gear 505, the duct 605 swings in one direction. When the intermittent gear 505 is not meshing with the gear 505, the duct 605 swings in the opposite direction under the action of a spiral spring 508. This achieves automatic reciprocating swing of the duct 605, which reduces the labor intensity of workers while effectively suppressing dust at construction sites.
