Description

Technical Field

[0001] This utility model relates to the field of dust prevention device technology, and in particular to a dust prevention device for building demolition. Background Technology

[0002] With the development of the times, many old residential areas and buildings are facing the need for demolition and reconstruction. However, during the physical demolition process, a large amount of dust is generated at the construction site, which not only seriously pollutes the air, but also poses a threat to the life and health of construction workers. To deal with this problem, construction sites are usually equipped with dust suppression devices. These devices effectively adsorb and settle dust particles in the air by spraying fine water mist, thereby significantly reducing the dust concentration at the construction site and creating a safer and healthier working environment for construction workers.

[0003] To expand the spray coverage area of ​​dust suppression devices, the conventional approach is to use oscillating spraying technology, which increases the fan-shaped range of the spray angle through mechanical oscillation. However, while this oscillating spraying mechanism expands the horizontal coverage angle, the vertical spray distance (i.e., the effective radius of action) of the device does not increase simultaneously, resulting in a limited ability to adsorb long-distance suspended dust. This contradiction between spray distance and coverage angle ultimately restricts the full realization of the overall protective effectiveness of the dust suppression device, making it difficult to form a continuous and effective three-dimensional dust barrier. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides the following technical solution: a dustproof device for building demolition, comprising a mobile water tank, wherein a rotating disc is rotatably connected to the top center of the mobile water tank;

[0005] A power mechanism for driving the rotating disk to rotate is fixedly installed on the top of the mobile water tank and on the right side of the rotating disk.

[0006] The top of the rotating disc is arranged in an arc shape and is equipped with a spraying mechanism to expand the dust suppression coverage angle.

[0007] The top center of the rotating disk is fan-shaped and equipped with a wind mechanism for increasing the spray radius. The wind mechanism is slidably engaged with the spray mechanism.

[0008] As an improvement to the above technical solution, the power mechanism includes a reciprocating motor, a drive gear, and an arc gear. The reciprocating motor is fixedly installed on the top of the mobile water tank via a bracket plate and located on the right side of the rotating disk. The right end of the drive gear is fixedly installed with the output end of the reciprocating motor. The arc gear is fixedly installed on the top right side of the rotating disk, and the drive gear meshes with the arc gear.

[0009] As an improvement to the above technical solution, the spraying mechanism includes a spherical tube, a first water supply pipe, a second water supply pipe, an atomizing nozzle, and a spring telescopic lever. The top of the rotating disc near its edge has multiple spherical slots in an arc shape. The spherical tube is movably engaged in the spherical slots. The top end of the first water supply pipe is fixedly installed to the bottom outer side of the spherical tube. The bottom end of the second water supply pipe is fixedly installed to the top outer side of the spherical tube. The atomizing nozzles are linearly and uniformly arranged and fixedly installed on the outside of the second water supply pipe. The spring telescopic lever is fixedly installed at the top end of the second water supply pipe.

[0010] As an improvement to the above technical solution, the wind power mechanism includes a drive motor, a power rod, fan blades, a differential assembly, a driven rod, and an assist plate. The drive motor is fixedly installed at the top center of the rotating disk. The bottom end of the power rod is fixedly installed with the output end of the drive motor. The fan blades are fixedly installed on the outside of the power rod. The differential assembly is fixedly installed at the top of the power rod. The bottom end of the driven rod is fixedly installed with the top of the differential assembly. The assist plate is fixedly installed at the top of the driven rod. A wavy groove is formed at the bottom of the assist plate away from the center. The wavy groove is movably engaged with a spring telescopic lever. There is a certain gap between the outer top of the spring telescopic lever and the inner walls of both sides of the wavy groove.

[0011] As an improvement to the above technical solution, the inner wall of the spherical slot is provided with an arc-shaped limiting slot, and an arc-shaped limiting block is fixedly installed on the outer side of the spherical tube, and the arc-shaped limiting slot and the arc-shaped limiting block are movably engaged.

[0012] As an improvement to the above technical solution, a fixing plate is fixedly installed on the right side of the differential assembly, and the end of the fixing plate away from the differential assembly is fixedly installed to the top of the rotating disk.

[0013] The beneficial effects of this utility model are as follows: When dust suppression is required during the demolition of buildings, the power mechanism, in conjunction with the rotating disc, drives the spraying mechanism and the wind mechanism to rotate reciprocally. While the spraying mechanism sprays fine water mist for dust suppression, the wind mechanism generates wind and drives the spraying mechanism to swing, causing the spraying mechanism to swing up and down during rotation to spray fine water mist for dust suppression. At the same time, the wind mechanism also enhances the spray radius of the water mist. This synergistic optimization of spraying distance and coverage ultimately promotes the full display of the overall protective effectiveness of the dust suppression device, enabling it to build a continuous and efficient three-dimensional dust barrier.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0021] Reference Appendix Figure 1 ,exist Figure 1 In the diagram, 'a' points to the front view and 'b' points to the right-side view. These views are only used to understand the scheme.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a dust prevention device for building demolition, including a mobile water tank 1, with a rotating disc 2 rotatably connected to the top center of the mobile water tank 1;

[0023] A power mechanism for driving the rotating disk 2 to rotate is fixedly installed on the top of the mobile water tank 1 and on the right side of the rotating disk 2;

[0024] The top of the rotating disc 2 is arranged in an arc shape and is equipped with a spraying mechanism to expand the dust suppression coverage angle;

[0025] The top center of the rotating disc 2 is fan-shaped and equipped with a wind mechanism for increasing the spray radius. The wind mechanism and the spray mechanism are slidably engaged.

[0026] In this implementation plan, a large amount of particulate dust is generated during the demolition of buildings. The power mechanism, in conjunction with the rotating disk 2, drives the spraying mechanism and the wind mechanism to rotate back and forth. When the spraying mechanism sprays fine water mist to suppress dust, the wind mechanism generates wind and drives the spraying mechanism to swing. This causes the spraying mechanism to swing up and down during rotation, spraying fine water mist. The fine water mist can adsorb and suppress the surrounding suspended dust. At the same time, the wind mechanism also increases the spray radius of the water mist, enabling the device to build a continuous and efficient three-dimensional dust barrier and enhance the dust suppression capability of the device.

[0027] Specifically, the power mechanism includes a reciprocating motor 3, a drive gear 31, and an arc gear 32. The reciprocating motor 3 is fixedly installed on the top of the mobile water tank 1 via a bracket plate and located on the right side of the rotating disk 2. The right end of the drive gear 31 is fixedly installed with the output end of the reciprocating motor 3. The arc gear 32 is fixedly installed on the top right side of the rotating disk 2, and the drive gear 31 meshes with the arc gear 32.

[0028] In this embodiment, the rotating disk 2 is driven to rotate by the cooperation of the internal structure of the power mechanism, thereby enabling the spraying mechanism to rotate and spray.

[0029] Specifically, the spraying mechanism includes a spherical tube 41, a first water supply pipe 42, a second water supply pipe 43, an atomizing nozzle 44, and a spring telescopic lever 45. The top of the rotating disc 2 is provided with multiple spherical slots 4 in an arc shape near the edge. The spherical tube 41 is movably engaged in the spherical slots 4. The top end of the first water supply pipe 42 is fixedly installed to the bottom outer side of the spherical tube 41, and the bottom end of the second water supply pipe 43 is fixedly installed to the top outer side of the spherical tube 41. The atomizing nozzles 44 are linearly and evenly arranged and fixedly installed on the outside of the second water supply pipe 43. The spring telescopic lever 45 is fixedly installed at the top end of the second water supply pipe 43.

[0030] In this embodiment, the water flow can be atomized and sprayed out through the cooperation of the internal structure of the spraying mechanism, which also provides the basic conditions for the wind power mechanism to drive the spraying mechanism to swing.

[0031] Specifically, the wind power mechanism includes a drive motor 5, a power rod 51, a fan blade 52, a differential assembly 53, a driven rod 54, and an assist plate 55. The drive motor 5 is fixedly installed at the top center of the rotating disk 2. The bottom end of the power rod 51 is fixedly installed with the output end of the drive motor 5. The fan blade 52 is fixedly installed on the outside of the power rod 51. The differential assembly 53 is fixedly installed at the top of the power rod 51. The bottom end of the driven rod 54 is fixedly installed with the top of the differential assembly 53. The assist plate 55 is fixedly installed at the top of the driven rod 54. A wavy groove 56 is provided at the bottom of the assist plate 55 away from the center. The wavy groove 56 is movably engaged with the spring telescopic rod 45. There is a certain gap between the outer top of the spring telescopic rod 45 and the inner walls of both sides of the wavy groove 56.

[0032] In this embodiment, the spraying mechanism is driven to swing by the cooperation of the internal structure of the wind power mechanism, which also simultaneously enhances the spray atomization radius.

[0033] Specifically, the inner wall of the spherical slot 4 is provided with an arc-shaped limiting slot, and an arc-shaped limiting block is fixedly installed on the outer side of the spherical tube 41. The arc-shaped limiting slot and the arc-shaped limiting block are movably engaged.

[0034] In this embodiment, the second water supply pipe 43 is restricted by the movable engagement of the arc-shaped limiting slot and the arc-shaped limiting block, so that the second water supply pipe 43 can only swing on the same horizontal plane.

[0035] Specifically, a mounting plate is fixedly installed on the right side of the differential assembly 53, and the end of the mounting plate away from the differential assembly 53 is fixedly installed on the top of the rotating disc 2.

[0036] In this embodiment, the differential assembly 53 is supported and fixed by a fixing plate.

[0037] During use, water is injected into the mobile water tank 1 and moved to a suitable position. Since how the water in the mobile water tank 1 is sprayed from the atomizing nozzle 44 is existing technology, it will not be explained in detail. The CPU controls the switching of the reciprocating motor 3 and the drive motor 5, as well as when the water is sprayed. During dismantling, when dust suppression is needed, the reciprocating motor 3 is started. The reciprocating motor 3 drives the drive gear 31 to rotate reciprocally. The drive gear 31, through meshing with the arc gear 32, drives the rotating disk 2 to rotate reciprocally. The rotating disk 2 drives the spraying mechanism and the wind mechanism to rotate reciprocally. At this time, the drive motor 5 is started, driving the power rod 51 to rotate at high speed. The power rod 51 drives the fan blade 52 to rotate at high speed. When the fan blade 52 rotates at high speed, it drives the airflow away from the power rod 51. Simultaneously, the power rod 51, with the cooperation of the differential assembly 53, drives the driven rod 5... 4. The driven rod 54 drives the auxiliary plate 55 to rotate at a low speed. The auxiliary plate 55 drives the wave-shaped groove 56 to rotate. When the wave-shaped groove 56 rotates, under the restriction of the arc-shaped limiting block, it drives the spring telescopic rod 45 to swing around the spherical tube 41. The spring telescopic rod 45 drives the second water supply pipe 43 to swing around the spherical tube 41. The second water supply pipe 43 drives the atomizing nozzle 44 to swing around the spherical tube 41. This causes the atomizing nozzle 44 to swing up and down during the rotation, spraying fine water mist for dust suppression. At the same time, the fan blade 52 drives the water mist sprayed by the atomizing nozzle 44 to move to a farther position, thereby simultaneously increasing the spray radius of the atomizing nozzle 44. This synergistic optimization of spray distance and coverage area ultimately promotes the full display of the overall protective effectiveness of the dust suppression device, enabling it to build a continuous and efficient three-dimensional dust barrier.
