Description

Technical Field

[0001] This utility model relates to the field of fogging technology, and in particular to an easily adjustable dust suppression fogging device for building construction. Background Technology

[0002] Dust suppression is a very important task during construction. To facilitate dust suppression, many construction sites install fogging stations along roadsides and in dusty areas. The nozzles at the top of the fogging stations effectively suppress dust in the air.

[0003] For example, Chinese utility model patent application number 202420745404.2 discloses a fog pile rotating spray mechanism, including a fog pile top seat and a rotating seat rotatably mounted on top of the fog pile top seat. A rotating nozzle is installed on the top of the rotating seat. A driven gear is fixed on the surface of the through-tube base. A servo reduction motor is fixed on the inner wall of one side of the fog pile top seat. A driving gear that meshes with the driven gear is installed on the output end of the servo reduction motor. Two upright seats are symmetrically fixed on the top surface of the rotating seat. The rotating nozzle is rotated between the two upright seats. It also includes a limiting structure. This utility model improves and optimizes the existing rotating spray pile by adding upright seats, a top seat, and a limiting structure to its original structure. This allows the elevation angle of the rotating nozzle to be adaptively adjusted according to different needs during actual use, which improves the flexibility of the fog pile to a certain extent. Moreover, the elevation angle adjustment is very convenient and easy to operate.

[0004] The existing dust suppression mist spraying technology has a fixed and non-adjustable instantaneous spraying range. The spraying range can only be expanded by rotating the nozzle to achieve dust suppression in the target area. However, the rotating nozzle spraying results in intermittent water supply to the same area (water is sprayed only when the nozzle rotates to that position). The water volume per unit time is more dispersed, making it impossible to spray water to suppress dust in the entire target area. This may result in some areas of dust not being sprayed with water in time, leading to dust diffusion and affecting the overall dust suppression effect.

[0005] Therefore, it is necessary to provide an easily adjustable dust suppression fog pile for building construction to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an easily adjustable dust suppression fog pile for building construction.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a dust suppression fog pile for easy adjustment in construction, comprising a fog pile rod, a device box rotatably connected to the top of the fog pile rod, a water spraying mechanism and an adjustment mechanism being provided inside the device box, the adjustment mechanism being used to adjust the instantaneous spraying range of the water spraying mechanism, and a rotating mechanism being provided inside the fog pile rod near the top.

[0008] The water spraying mechanism includes an arc-shaped pipe fixedly installed on the inner wall of the device box, a plurality of water outlet pipes fixedly connected to the arc-shaped pipe, the other end of the water outlet pipes passing through the device box and fixedly connected to a nozzle, and a protective cover fixedly connected to the outside of the device box at the position corresponding to the nozzle.

[0009] The adjustment mechanism includes two sliding components and a drive motor. The output end of the drive motor is fixedly connected to a large gear, and a large gear is meshed on the outer surface of the large gear. Small gears are meshed on the outer surfaces of both the large gear and the large gear. Both sliding components are provided with arc-shaped racks, one end of which extends into the interior of an arc-shaped tube and is fixedly connected to an adjusting piston.

[0010] As a further description of the above technical solution: the water spraying mechanism also includes a second water supply pipe. One end of the second water supply pipe is fixedly connected to the middle position of the arc-shaped pipe. The other end of the second water supply pipe is rotatably connected to a first water supply pipe through a sealed bearing. A solenoid valve is installed on the first water supply pipe. The first water supply pipe is connected to an external water supply pipe. When the solenoid valve is opened, water from the external water supply pipe is supplied to the first water supply pipe, i.e., the water spraying mechanism is in operation. When the solenoid valve is closed, water supply to the first water supply pipe stops, and the water spraying mechanism is in a stopped state.

[0011] As a further description of the above technical solution: the sliding assembly includes an arc-shaped slide rail fixedly installed on the inner wall of the device box, and a slider is slidably connected inside the arc-shaped slide rail, and the slider is fixedly connected to the arc-shaped rack.

[0012] As a further description of the above technical solution: the drive motor is fixedly installed at the bottom of the inner wall of the device box, and the large gear and the two small gears are rotatably installed at the bottom of the inner wall of the device box. The two small gears are respectively meshed with the two arc-shaped racks.

[0014] As a further description of the above technical solution: the rotating mechanism includes a second drive motor fixedly installed on the inner wall of the fog pile pole, and a rotating gear is fixedly connected to the output end of the second drive motor, and a rotating gear ring meshes with the outer surface of the rotating gear.

[0015] As a further description of the above technical solution: the rotating gear ring is fixedly connected to the bottom of the device box.

[0016] As a further description of the above technical solution: a power distribution box is fixedly connected to the outer surface of the fog pile near the bottom end. The power distribution box is equipped with a control panel (not shown in the figure). The control panel is electrically connected to drive motor one, drive motor two and solenoid valve, and is used to control drive motor one, drive motor two and solenoid valve to open or close.

[0017] This utility model has the following beneficial effects:

[0018] 1. Compared with existing technologies, the easily adjustable dust suppression fogging system used in this construction project rotates clockwise or counterclockwise through the output of a drive motor. This rotation, via a large gear and two small gears, drives two arc-shaped racks to move, which in turn moves two adjusting pistons inside the arc-shaped tube. This causes the space between the two adjusting pistons to shrink or increase, thereby adjusting the size of the water flow space within the arc-shaped tube. This indirectly adjusts the number of nozzles used, allowing for the selection of an appropriate number of nozzles based on the area of ​​the target dust suppression zone. This adjusts the instantaneous spray range of the water spraying mechanism to match the area of ​​the target dust suppression zone, ensuring full coverage dust suppression throughout the target area. This guarantees timely dust suppression when dust is generated in the target area, improving the overall dust suppression effect and efficiency.

[0019] 2. Compared with the existing technology, the adjustable dust suppression fog pile used in this construction project drives the rotating gear to rotate through the output end of the second drive motor, which in turn drives the rotating gear ring meshing with it to rotate, thereby driving the device box to rotate, so as to adjust the position of the nozzles and facilitate dust suppression treatment at different locations.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Reference Figure 1-5 This utility model provides an easily adjustable dust suppression fogging device for building construction: it includes a fogging pole 1, the top of which is rotatably connected to a device box 2, the inside of which is a water spraying mechanism 3 and an adjustment mechanism 4, the adjustment mechanism 4 being used to adjust the instantaneous spraying range of the water spraying mechanism 3, and a rotating mechanism 5 being provided inside the fogging pole 1 near the top.

[0029] The water spraying mechanism 3 includes an arc-shaped pipe 31 fixedly installed on the inner wall of the device box 2. Several water outlet pipes 32 are fixedly connected to the arc-shaped pipe 31. The other end of the water outlet pipe 32 passes through the device box 2 and is fixedly connected to a nozzle 33. A protective cover 7 is fixedly connected to the outside of the device box 2 at the position corresponding to the nozzle 33. The water spraying mechanism 3 also includes a second water supply pipe 34. One end of the second water supply pipe 34 is fixedly connected to the middle position of the arc-shaped pipe 31. The other end of the second water supply pipe 34 is rotatably connected to a first water supply pipe 36 through a sealed bearing 35. A solenoid valve 37 is installed on the first water supply pipe 36. The first water supply pipe 36 is connected to an external water supply pipeline. The first water supply pipe 36 is fixedly connected to the fog pile rod 1 through a fixing bracket (not shown in the figure). When the solenoid valve 37 is opened, the water source in the external water supply pipeline supplies water to the first water supply pipe 36, that is, the water spraying mechanism 3 is in the running state. When the solenoid valve 37 is closed, the water supply to the first water supply pipe 36 is stopped, and the water spraying mechanism 3 is in the stopped state.

[0030] The adjustment mechanism 4 includes two sliding components 41 and a drive motor 42. The output end of the drive motor 42 is fixedly connected to a large gear 43. The outer surface of the large gear 43 is meshed with a large gear 44. The outer surfaces of both the large gear 43 and the large gear 44 are meshed with small gears 45. Both sliding components 41 are provided with arc-shaped racks 46. One end of the arc-shaped rack 46 extends into the interior of the arc-shaped tube 31 and is fixedly connected to an adjusting piston 47. The adjusting piston 47 is configured to be interference-fitted with the inner wall of the arc-shaped tube 31.

[0031] The output of the drive motor 42 rotates clockwise or counterclockwise, and through the transmission of the large gear 43, the large gear 44, and the two small gears 45, it drives the two arc-shaped racks 46 to move, which in turn drives the two adjusting pistons 47 to move inside the arc-shaped tube 31. This causes the space between the two adjusting pistons 47 to shrink or increase, thereby adjusting the size of the water flow space inside the arc-shaped tube 31. This indirectly adjusts the number of spray heads 33 used, allowing the appropriate number of spray heads 33 to be selected according to the area of ​​the target area to be dusted. This adjusts the instantaneous spray range of the water spraying mechanism 3 to match the area of ​​the target area to be dusted, so that the target area can be fully covered by water spraying for dust suppression. This ensures that water can be sprayed in time when dust is generated, improving the overall dust suppression effect and efficiency.

[0032] The sliding component 41 includes an arc-shaped slide rail 411 fixedly installed on the inner wall of the device box 2. A slider 412 is slidably connected inside the arc-shaped slide rail 411. The slider 412 is fixedly connected to the arc-shaped rack 46. The sliding component 41 can limit the arc-shaped rack 46 and improve the stability of the arc-shaped rack 46 during movement.

[0033] The drive motor is fixedly installed at the bottom of the inner wall of the device box 2. The large gear 44 and the two small gears 45 are rotatably installed at the bottom of the inner wall of the device box 2. The two small gears 45 are respectively meshed with the two arc-shaped racks 46.

[0034] The rotating mechanism 5 includes a second drive motor 51 fixedly installed on the inner wall of the fog pile pole 1. The output end of the second drive motor 51 is fixedly connected to a rotating gear 52. A rotating gear ring 53 meshes with the outer surface of the rotating gear 52. The rotating gear ring 53 is fixedly connected to the bottom of the device box 2.

[0035] The output of the drive motor 51 rotates, which drives the rotating gear 52 to rotate, and drives the rotating gear ring 53 that meshes with it to rotate, thereby driving the device box 2 to rotate, so as to adjust the position of the nozzle 33 to facilitate dust suppression at different positions.

[0036] A power distribution box 6 is fixedly connected to the outer surface of the fog cone pole 1 near the bottom. The power distribution box 6 has a control panel (not shown in the figure) inside. The control panel is electrically connected to the drive motor 42, the drive motor 51 and the solenoid valve 37, and is used to control the drive motor 42, the drive motor 51 and the solenoid valve 37 to open or close.

[0037] Working principle: In use, the operator first turns on drive motor 2 51 via the control panel. The output of drive motor 2 51 rotates, driving the rotating gear 52 to rotate, which in turn drives the rotating gear ring 53 meshing with it to rotate, thereby driving the device box 2 to rotate, so as to adjust the position of the nozzle 33 so that the nozzle 33 corresponds to the position of the target area to be dusted. Then, the instantaneous spraying range of the water spraying mechanism 3 is adjusted according to the area of ​​the target area to be dusted to make it suitable. Drive motor 1 42 is turned on via the control panel. The output of drive motor 1 42 rotates clockwise or counterclockwise, driving the large gear 1 43 to rotate, which in turn drives the small gear 45 and the large gear 2 44 meshing with it to rotate. Then, the large gear 2 44 drives the small gear 45 meshing with it to rotate. The rotation of wheel 45 causes two small gears 45 to rotate in opposite directions, which in turn drives two arc-shaped racks 46 that mesh with them to move. This, in turn, drives two adjusting pistons 47 to move inside the arc-shaped tube 31, causing the space between the two adjusting pistons 47 to shrink or increase. This adjusts the size of the space in the arc-shaped tube 31 where water can flow, and indirectly adjusts the number of nozzles 33 used. The appropriate number of nozzles 33 can be selected according to the area of ​​the target area to be dusted, thereby adjusting the instantaneous spraying range of the water spraying mechanism 3 to match the area of ​​the target area to be dusted. This ensures that the target area to be dusted can be fully covered by water spraying for dust suppression, and ensures that water can be sprayed to suppress dust in time when dust is generated, thus improving the overall dust suppression effect and efficiency.

[0038] After the instantaneous spray range of the water spraying mechanism 3 is adjusted, the solenoid valve 37 is opened through the control panel. The water source in the external water supply pipe flows into the arc-shaped pipe 31 through the first water supply pipe 36 and the second water supply pipe 34 in sequence. The water flow is blocked by the two adjusting pistons 47, so that the water flow can only flow between the two adjusting pistons 47 in the arc-shaped pipe 31. Then the water flow flows to the nozzle 33 through the outlet pipe 32, and finally the nozzle 33 sprays the water flow to the target area to be dusted.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
