Description

Technical Field

[0001] This invention belongs to the field of construction site dust removal technology, and in particular relates to a high-efficiency dust removal device for construction sites. Background Technology

[0002] In construction sites and other dusty environments, dust pollution not only affects workers' health and work efficiency but can also pollute the surrounding environment. Traditional dust control methods, such as water truck spraying and fixed spray systems, can alleviate dust problems to some extent, but these methods often suffer from limited coverage, inconvenient operation, high water consumption, and low efficiency. Furthermore, traditional equipment typically lacks intelligent control functions and cannot automatically adjust parameters according to changes in the actual working environment, making it difficult to achieve highly efficient and energy-saving dust control effects.

[0003] With the advancement of technology and increasingly stringent environmental protection requirements, developing a highly efficient dust removal device that can flexibly adapt to different construction site conditions and possess intelligent control capabilities has become an urgent priority. Therefore, addressing the shortcomings of existing technologies, there is a pressing need to develop a high-efficiency dust removal device for construction sites to overcome current limitations and improve dust removal efficiency and intelligence. Such a device would not only meet the needs of modern green construction but also significantly improve air quality at construction sites, ensuring the health and safety of workers. Summary of the Invention

A support and adjustment assembly is installed on the lower side of the water supply box. The support and adjustment assembly is used to support the water supply box and adjust its height and angle. The device also includes:

[0007] A water supply cylinder is fixed to the other side of the water supply box. A second chamber is formed inside the water supply cylinder, and an impeller shaft is rotatably mounted inside the second chamber. An impeller is fixed on the impeller shaft, and one end of the impeller shaft is connected to one of the circumferentially oscillating dust removal components via a connecting rod. A third chamber is formed inside the water supply box, and the second chamber is connected to the third chamber via a through hole. Multiple circumferentially oscillating dust removal components are also connected to the third chamber. A water source pipe is installed on the water supply cylinder and connected to the end of the second chamber furthest from the water supply box.

[0008] The water supply box is also equipped with a control drive assembly for controlling and driving the impeller shaft. When the flow rate of water from the water source pipe to chamber two is less than a preset value, the control drive assembly drives the impeller shaft, and the water is sequentially conveyed through chamber two, the through hole, and the three-dimensional circumferential oscillating dust removal assembly. Simultaneously, under the drive of the transmission assembly, all the circumferential oscillating dust removal assemblies rotate to perform circumferential oscillating dust removal operations. When the flow rate of water from the water source pipe to chamber two is greater than the preset value, the control drive assembly releases the driving state of the impeller shaft, and the water is sequentially conveyed through chamber two, the through hole, and the three-dimensional circumferential oscillating dust removal assembly. Simultaneously, the water drives the impeller to rotate, and under the drive of the transmission assembly, all the circumferential oscillating dust removal assemblies rotate to perform circumferential oscillating dust removal operations.

[0009] A further technical solution includes a linear push-pull cylinder hinged to both ends of the lower side of the water supply box. An arc-shaped push-pull cylinder is fixed between the telescopic spindle of the linear push-pull cylinder and the water supply box. A stabilizing cylinder is sleeved on the cylinder body of the linear push-pull cylinder. A locking bolt for locking and fixing the linear push-pull cylinder is installed on the stabilizing cylinder. An assembly plate is fixed across one side of the two stabilizing cylinders. Positioning holes are opened at the four corners of the assembly plate.

[0010] A further technical solution includes a circumferential oscillating dust removal assembly comprising a water distribution pipe rotatably mounted on the side of the water supply box and connected to the chamber three-way junction; a concave frame rotatably mounted on the water distribution pipe; the two sides of the middle portion of the concave frame are fixedly connected to the water supply box via corner brackets; a closed-loop frame is provided between the two branches of the concave frame; two support shafts are fixed on both sides of the closed-loop frame, and the two support shafts are rotatably connected to the ends of the two branches of the concave frame; a swaying tube passes through the inner side of the closed-loop frame; two support shafts are fixed on both sides of the swaying tube, and the two support shafts are rotatably connected to the two sides of the closed-loop frame; a rotating plate is fixed to the end of the water distribution pipe; a connecting pipe is fixed to the rotating plate; one end of the swaying tube is rotatably connected to the connecting pipe in a sealed manner; a fine mist nozzle is rotatably connected to the end of the swaying tube away from the connecting pipe in a sealed manner; a water guide pipe is also fixed between the rotating plate and the water distribution pipe; the inner cavity of the swaying tube is connected to the inner cavity of the water guide pipe through the inner cavity of the connecting pipe; the water guide pipe is also connected to the inner cavity of the water distribution pipe.

[0011] In a further technical solution, the first and second support shafts are perpendicular; the rotating plate adopts a V-shaped structure, one branch of the rotating plate is fixedly connected to the end of the water distribution pipe, the connecting pipe is perpendicularly fixedly connected to the other branch of the rotating plate, and the swing pipe and the connecting pipe are coaxial.

[0012] In a further technical solution, the transmission assembly includes a synchronous pulley fixed on the water distribution pipe, and two adjacent synchronous pulleys are connected by a linkage belt.

[0013] In a further technical solution, both the third chamber and the through hole adopt a conical structure. The large end of the through hole is connected to the second chamber, and the water distribution pipe is connected to the small end of the third chamber. Furthermore, multiple through holes are evenly distributed around the outer circumference of the impeller shaft.

[0014] In a further technical solution, the water supply cylinder is fixedly connected to the middle of the water supply box, and the impeller shaft is connected to the water distribution pipe of a circumferentially oscillating dust removal component in the middle via a connecting rod; multiple connecting rods are evenly distributed circumferentially.

[0015] A further technical solution includes a control drive component comprising an electric motor with a power frame fixed to it. Both ends of the power frame are fixedly connected to the water supply box via linear push-pull cylinders. A chamber 1 is also formed inside the water supply cylinder on the side of chamber 2 away from the water supply box. The output shaft of the electric motor extends into chamber 1, and a connector is fixed to the end of the output shaft. A mating groove is formed at the end of the impeller shaft, allowing for transmission connection with the connector. When the flow rate of water from the water source pipe to chamber 2 is less than a preset value, the linear push-pull cylinder 2 shortens, connecting the connector to the mating groove, and then the electric motor is started to drive the impeller shaft. When the flow rate of water from the water source pipe to chamber 2 is greater than the preset value, the linear push-pull cylinder 2 extends, separating the connector from the mating groove, and then the electric motor stops, releasing the impeller shaft from its driving state.

[0016] A further technical solution is that the motor and the impeller shaft are arranged coaxially, the impeller shaft and one of the water distribution pipes are arranged coaxially, one end of the impeller shaft is sealed and rotates into the third chamber, and the other end of the impeller shaft is sealed and rotates into the first chamber; a bushing is fixed in the middle of the end of the water supply cylinder away from the water supply box, and the output shaft of the motor is slidably and rotatably connected to the bushing; the connector adopts a frustum structure.

[0017] The present invention provides a high-efficiency dust removal device for construction sites, which has the following beneficial effects:

[0018] By using the support and adjustment components, the water supply box can be installed at a suitable height and angle, i.e., a suitable location on the construction site, thereby improving the dust removal effect.

[0019] By arranging multiple circumferential oscillating dust removal components on the water supply box, and connecting adjacent circumferential oscillating dust removal components through a transmission component, the requirement for large-area synchronous drive dust removal is met.

[0020] Through the arrangement of the impeller, connecting rod, water supply pipe and control drive assembly, when the flow rate of water supplied to chamber two through the water supply pipe is less than the preset value, the control drive assembly drives the impeller shaft. The water is then transported sequentially through chamber two, the through hole and the three-way circumferential oscillating dust removal assembly. At the same time, driven by the transmission assembly, all the circumferential oscillating dust removal assemblies rotate to perform circumferential oscillating dust removal operations.

[0021] When the flow rate of water supplied from the water source pipeline to chamber two exceeds the preset value, the control drive component releases the drive state of the impeller shaft. The water is then conveyed sequentially through chamber two, the through hole, and the three-dimensional circumferential oscillating dust removal components. At the same time, the water drives the impeller to rotate, and under the drive of the transmission component, all the circumferential oscillating dust removal components rotate to perform circumferential oscillating dust removal operations. This allows for flexible adjustment based on the water flow rate to meet the needs of circumferential oscillating dust removal, resulting in energy saving, environmental protection, and a high degree of intelligence.

[0022] In summary, this invention can flexibly adjust the dust removal operation according to the water supply flow rate, achieving efficient and energy-saving large-area dust removal. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0033] like Figures 1-7 As shown, an embodiment of the present invention provides a high-efficiency dust removal device for construction sites, including a water supply box 8 and a water source pipe 14, and further comprising:

[0034] A support and adjustment assembly is installed on the lower side of the water supply box 8. The support and adjustment assembly is used to support the water supply box 8 and adjust its height and angle.

[0035] A circumferential oscillating dust removal assembly 6 is provided. Multiple circumferential oscillating dust removal assemblies 6 are installed on one side of the water supply box 8, and two adjacent circumferential oscillating dust removal assemblies 6 are connected by a transmission assembly.

[0036] A water supply cylinder 11 is fixed to the other side of the water supply box 8. A second chamber 29 is opened inside the water supply cylinder 11. An impeller shaft 33 is rotatably installed in the second chamber 29. An impeller 32 is fixed on the impeller shaft 33. One end of the impeller shaft 33 is also connected to one of the circumferential oscillating dust removal components 6 through a connecting rod 36. A third chamber 35 is opened inside the water supply box 8. The second chamber 29 is connected to the third chamber 35 through a through hole 34. Multiple circumferential oscillating dust removal components 6 are all connected to the third chamber 35. The water source pipe 14 is installed on the water supply cylinder 11 and is connected to the end of the second chamber 29 away from the water supply box 8.

[0037] The water supply box 8 is also equipped with a control drive assembly for controlling and driving the impeller shaft 33. When the flow rate of water supplied from the water source pipe 14 to the second chamber 29 is less than a preset value, the control drive assembly drives the impeller shaft 33. The water is then sequentially transported through the second chamber 29, the through hole 34, and the third chamber 35 to the circumferential oscillating dust removal assembly 6. Simultaneously, under the drive of the transmission assembly, all the circumferential oscillating dust removal assemblies 6 rotate to perform circumferential oscillating dust removal operations. When the flow rate of water supplied from the water source pipe 14 to the second chamber 29 is greater than the preset value, the control drive assembly releases the driving state of the impeller shaft 33. The water is then sequentially transported through the second chamber 29, the through hole 34, and the third chamber 35 to the circumferential oscillating dust removal assembly 6. Simultaneously, the water drives the impeller 32 to rotate, and under the drive of the transmission assembly, all the circumferential oscillating dust removal assemblies 6 rotate to perform circumferential oscillating dust removal operations.

[0038] In this embodiment of the invention, the water supply box 8 can be installed at a suitable height and angle, i.e., a suitable location on the construction site, by means of a support and adjustment component, thereby improving the dust removal effect. By arranging multiple circumferential oscillating dust removal components 6 on the water supply box 8, and connecting adjacent circumferential oscillating dust removal components 6 through a transmission component, the requirement for large-area synchronous drive dust removal is met. Through the arrangement of impeller 32, connecting rod 36, water supply pipe 14, and control drive assembly, when the flow rate of water supplied from water supply pipe 14 to chamber 29 is less than a preset value, the control drive assembly drives impeller shaft 33. Water is sequentially transported through chamber 29, through hole 34, and chamber 35 to circumferential oscillating dust removal assembly 6. Simultaneously, under the drive of transmission assembly, all circumferential oscillating dust removal assemblies 6 rotate to perform circumferential oscillating dust removal operations. When the flow rate of water supplied from water supply pipe 14 to chamber 29 is greater than a preset value, the control drive assembly releases the drive state of impeller shaft 33. Water is sequentially transported through chamber 29, through hole 34, and chamber 35 to circumferential oscillating dust removal assembly 6. Simultaneously, the water drives impeller 32 to rotate, and under the drive of transmission assembly, all circumferential oscillating dust removal assemblies 6 rotate to perform circumferential oscillating dust removal operations. That is, the flow rate can be flexibly adjusted according to the water supply speed to meet the needs of circumferential oscillating dust removal, which is energy-saving, environmentally friendly, and highly intelligent.

[0039] It should be noted that the preset value of the flow rate of water from the water source pipe 14 to the second chamber 29 can be set through specific experiments and actual needs, as long as it meets the driving requirements of the circumferential oscillating dust removal component 6, without limitation or elaboration.

[0040] like Figures 1-2As shown, in a preferred embodiment of the present invention, the support adjustment assembly includes a linear push-pull cylinder 3 hinged to both ends of the lower side of the water supply box 8. An arc-shaped push-pull cylinder 13 is fixed between the telescopic spindle of the linear push-pull cylinder 3 and the water supply box 8. The arc-shaped push-pull cylinder 13 is adapted for installation to ensure stable and reliable angle adjustment. The water supply box 8 can be adjusted in height through the linear push-pull cylinder 3. A stabilizing cylinder 4 is sleeved on the cylinder body of the linear push-pull cylinder 3. A locking bolt 5 for locking and fixing the linear push-pull cylinder 3 is installed on the stabilizing cylinder 4. An assembly plate 2 is fixed across one side of the two stabilizing cylinders 4. Positioning holes 1 are opened at the four corners of the assembly plate 2. The linear push-pull cylinder 3 can be supported and fixed through the cooperation of the assembly plate 2 and the stabilizing cylinder 4, and the installation is convenient. The positioning holes 1 opened at the four corners of the assembly plate 2 can be used to fix the device to the fence of the construction site or other locations to meet the dust removal requirements.

[0041] like Figures 3-5 As shown in a preferred embodiment of the present invention, the circumferential oscillating dust removal assembly 6 includes a water distribution pipe 24 rotatably mounted on the side of the water supply box 8 and communicating with the chamber 35. A concave frame 20 is rotatably mounted on the water distribution pipe 24. The two sides of the middle part of the concave frame 20 are also fixedly connected to the water supply box 8 through corner brackets 25, which serve to support the concave frame 20. A closed-loop frame 18 is provided between the two branches of the concave frame 20. Support shafts 19 are fixed on both sides of the closed-loop frame 18. The two support shafts 19 are rotatably connected to the ends of the two branches of the concave frame 20. A swing tube 16 passes through the inner side of the closed-loop frame 18. Support shafts 17 are fixed on both sides of the swing tube 16. The two support shafts 17 are rotatably connected to the two sides of the closed-loop frame 18. The support shafts 17 and 19 are perpendicular to each other to ensure the reliability of the oscillation.

[0042] A rotating plate 22 is fixed to the end of the water distribution pipe 24, and a connecting pipe 21 is fixed on the rotating plate 22. One end of the swing pipe 16 is sealed and rotatably connected to the connecting pipe 21, and a fine mist nozzle 15 is sealed and rotatably connected to the end of the swing pipe 16 away from the connecting pipe 21. The rotating plate 22 adopts a V-shaped structure. One branch of the rotating plate 22 is fixedly connected to the end of the water distribution pipe 24, and the connecting pipe 21 is perpendicularly fixedly connected to the other branch of the rotating plate 22. The swing pipe 16 and the connecting pipe 21 are coaxial.

[0043] A water guide pipe 23 is also fixed between the rotating plate 22 and the water distribution pipe 24. The inner cavity of the swing pipe 16 is connected to the inner cavity of the water guide pipe 23 through the inner cavity of the connecting pipe 21. The water guide pipe 23 is also connected to the inner cavity of the water distribution pipe 24, so as to realize reliable water delivery. Especially when the water distribution pipe 24 rotates and the rotating plate 22 drives the swing pipe 16 to swing in a circle, reliable water delivery can be guaranteed. The layout is reasonable and reliable.

[0044] The transmission assembly includes a synchronous wheel 26 fixed on the water distribution pipe 24. Two adjacent synchronous wheels 26 are connected by a linkage belt 7. The synchronous wheels 26 can be arranged in a double groove structure to meet the requirements of cascade transmission. In this way, when one water distribution pipe 24 is driven, all water distribution pipes 24 can rotate synchronously, so that all the circumferential oscillating dust removal components 6 oscillate.

[0045] like Figures 1-2 , Figures 6-7 As shown, in a preferred embodiment of the present invention, both the third chamber 35 and the through hole 34 adopt a conical structure. The large end of the through hole 34 is connected to the second chamber 29, and the water distribution pipe 24 is connected to the small end of the third chamber 35. Furthermore, multiple through holes 34 are evenly distributed around the outer side of the impeller shaft 33, which can improve the efficiency of water delivery and thus enhance the effect of water being atomized and discharged through the fine mist nozzle 15.

[0046] The water supply cylinder 11 is fixedly connected to the middle of the water supply box 8, and the impeller shaft 33 is driven by a connecting rod 36 to the water distribution pipe 24 of a central circumferentially oscillating dust removal assembly 6. Multiple connecting rods 36 are evenly distributed circumferentially to ensure the reliability of the impeller shaft 33's transmission to the water distribution pipe 24. Furthermore, the impeller 32 is arranged according to existing conventional technology, requiring only that the water flow can drive the impeller 32 to rotate.

[0047] The control drive assembly includes a motor 12 coaxially arranged with the impeller shaft 33. A power frame 10 is fixed on the motor 12. Both ends of the power frame 10 are fixedly connected to the water supply box 8 through a linear push-pull cylinder 29. The linear push-pull cylinder 29 can drive the motor 12 to move its position. A chamber 28 is also provided in the water supply cylinder 11 on the side of the chamber 29 away from the water supply box 8. A bushing 27 is fixed in the middle of the end of the water supply cylinder 11 away from the water supply box 8. The output shaft of the motor 12 extends into the chamber 28 and is slidably and rotatably connected to the bushing 27. A connector 30 is fixed at the end of the output shaft of the motor 12. A docking groove 31 is provided at the end of the impeller shaft 33, which can be connected to the connector 30 for transmission. The connector 30 adopts a frustum structure to meet the requirements of connection and transmission.

[0048] When the flow rate of water supplied from the water source pipe 14 to the second chamber 29 is less than a preset value, the linear push-pull cylinder 29 shortens and connects the connector 30 to the docking groove 31, and then the motor 12 is started to drive the impeller shaft 33; when the flow rate of water supplied from the water source pipe 14 to the second chamber 29 is greater than the preset value, the linear push-pull cylinder 29 extends and separates the connector 30 from the docking groove 31, and then the motor 12 is stopped to release the driving state of the impeller shaft 33, avoiding the impeller shaft 33 sharing the torque driving motor 12, thus improving reliability.

[0049] Preferably, the impeller shaft 33 and one of the water distribution pipes 24 are arranged coaxially, with one end of the impeller shaft 33 being sealed and rotatably extended into the third chamber 35, and the other end of the impeller shaft 33 being sealed and rotatably extended into the first chamber 28, to ensure the reliability of the transmission.

[0050] The above embodiments of the present invention provide a high-efficiency dust removal device for construction sites, the working principle of which is as follows:

[0051] With the support adjustment components (including linear push-pull cylinder 3, arc push-pull cylinder 13 and stabilizing cylinder 4, etc.), the water supply box 8 can be installed at a suitable height and angle to optimize the dust removal effect.

[0052] Water from the water supply cylinder 11 is supplied to the second chamber 29 through the water supply pipe 14. When the water flow velocity is less than the preset value, the control drive component (mainly the motor 12) drives the impeller shaft 33; when the water flow velocity is greater than the preset value, the control drive component releases the drive state, allowing the water flow to naturally drive the impeller 32 to rotate.

[0053] Water flows from chamber 29 through the through hole 34 into chamber 35, then flows to the water distribution pipes 24 of each circumferentially oscillating dust removal component 6, and finally is discharged through the fine mist nozzles 15 on the oscillating pipe 16, thus realizing the atomization and spraying of water.

[0054] Each of the circumferential oscillating dust removal components 6 is connected by a transmission component (such as a synchronous pulley 26 and a linkage belt 7) to ensure that all components can rotate synchronously and perform circumferential oscillating dust removal operations. This not only improves dust removal efficiency but also expands the dust removal area.

[0055] The system automatically adjusts the state of the control drive components according to the speed at which water is delivered from water source pipeline 14 to chamber 29, ensuring stable operation of the system under different water supply flow rates, and achieving the goals of energy saving, environmental protection and intelligent operation.

[0056] In summary, this invention combines ingenious mechanical structure design with intelligent control to achieve efficient and flexible automated dust removal operations.

[0057] There are no specific limitations on the control, model and circuit connection of each component, which can be flexibly set in actual application.

[0058] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this invention does not involve any improvement to the software and methods.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
