Specific implementation mode

[0025] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0026] Please refer to Figures 1 - 14 , as shown in the figure, a dust reduction device for environmental protection building construction provided in this embodiment, please refer to Figures 1 - 3 , including a roof 1. A flow hole I 2 is opened at the top of the roof 1 by drilling with a drill press. A support device 3 is fixedly installed at a position corresponding to the flow hole I 2 at the top of the roof 1 by clamping. A support shaft 4 is movably sleeved on the outer surface of the support device 3 near the top by means of a bearing connection. A rotating device 5 is placed on the top of the support shaft 4. A stroke device 6 is movably installed on the top of the rotating device 5 by means of a sliding fit. A diversion device 7 is movably sleeved at the bottom of the rotating device 5 by means of an axial hole fit. The bottom of the diversion device 7 is movably sleeved with the flow hole I 2,

[0027] During the rotation of the device, the air inside the construction site will be driven by the diversion device 7 and flow from the inside of the construction site to the outside. At the same time, fresh air outside can also enter the inside of the construction site through the rotating device 5, thereby reducing the dust concentration in the construction site.

[0028] Furthermore, please refer to Figures 1 - 3 and Figures 7 - 9The rotating device 5 includes a contact plate 51, a connecting seat 52 is fixedly installed on the top of the contact plate 51 by welding, a travel hole I 53 is drilled on the top of the connecting seat 52 by drilling, the travel holes I 53 are distributed in a circular array, and the travel holes I 53 cooperate with the travel device 6 by sliding fit, an air circulation pipe 54 is fixedly installed on the bottom of the contact plate 51 near the inner circle by welding, and a fan blade 55 is fixedly installed inside the air circulation pipe 54 by welding, and the fan blade 55 is distributed in an array, and the bottom of the contact plate 51 is close to the inner circle. A fitting plate 56 is fixedly installed near the outer ring by welding, and the inner wall of the fitting plate 56 is fitted with the support shaft 4. An annular outer plate 57 is fixedly installed at the bottom of the fitting plate 56 by welding. Connecting holes II 58 are drilled at the bottom of the annular outer plate 57 near the inner ring by a drilling machine. The connecting holes II 58 are distributed in a circular array. The connecting holes II 58 are movably sleeved with the top of the guide device 7. Travel holes II 59 are drilled at the top of the annular outer plate 57 near the outer ring by a drilling machine. The travel holes II 59 are distributed in a circular array.

[0029] For further information, see Figures 1 - 6 and Figures 10 - 14, the flow guiding device 7 includes flow guiding vanes 71. Upper backing plates 72a and lower backing plates 72b are fixedly installed at positions near one end of the top and bottom of the flow guiding vanes 71 respectively by welding. An upper connecting shaft 73 is fixedly installed at a position near one end of the top of the upper backing plate 72a by welding. The upper connecting shaft 73 is movably sleeved with the connecting hole II 58 in a shaft-hole matching manner. A contact inclined plate 74 is fixedly installed at the top of the upper backing plate 72a by welding. A lower connecting shaft 75 is fixedly installed at a position near one end of the bottom of the lower backing plate 72b by welding. The lower connecting shaft 75 is movably sleeved with the connecting hole I 37 in a shaft-hole matching manner. The flow guiding vanes 71 are prone to damage in extremely harsh weather. In traditional devices, the flow guiding vanes 71 and the overall structure are integrally designed, making it difficult to replace them when they are damaged. However, in this application document, when the flow guiding vanes 71 are damaged, the rotating device 5 can be directly removed as a whole, and then the entire flow guiding device 7 can be disassembled, ensuring that the device can be in the best operating state, increasing the maintenance difficulty of the device, and reducing the use cost of the device. A return spring 76 is fixedly installed at the top of the upper connecting shaft 73 by clamping. The top of the return spring 76 is connected to the inner top of the connecting hole II 58 by clamping, enabling the entire flow guiding device 7 to rotate around the axes of the upper connecting shaft 73 and the lower connecting shaft 75. When the flow guiding vanes 71 are in the upwind position, when the airflow acts on the upwind surface of the flow guiding vanes 71 and drives the device to rotate, the upper connecting shaft 73 and the lower connecting shaft 75 will also rotate, thereby increasing the unfolding angle of the flow guiding vanes 71 and increasing their interaction area with the wind, generating a greater torque and improving their ventilation efficiency.

[0030] Further, please refer to Figures 7 - 9 and Figures 13 - 14 , the contact inclined plate 74 is located directly below the stroke hole II 59 in the initial state.

[0031] Further, please refer to Figures 1 - 6 and Figures 13 - 14 , the support device 3 includes a mounting pad 31. A flow hole II 32 is drilled at the top of the mounting pad 31. A connecting plate 33 is fixedly installed inside the flow hole II 32 by welding. A support sleeve 34 is fixedly installed on the inner side of the connecting plate 33 by welding. A support shaft 4 is movably sleeved on the outer surface of the support sleeve 34 near the top by bearing connection. A limit sleeve 35 is fixedly installed at a position on the top of the mounting pad 31 outside the flow hole II 32 by welding. A rotating sleeve 36 is sleeved on the top of the limit sleeve 35 in a rotational mating manner. A connecting hole I 37 is drilled at the top of the rotating sleeve 36. The connecting hole I 37 is distributed in a circular array. The connecting hole I 37 is movably sleeved with the bottom of the flow guiding device 7.

[0032] Furthermore, a conical plate 38 is fixedly installed at the bottom of the support sleeve 34 at a position below the roof 1 by welding, and an annular flow blocking plate 39 is fixedly installed at the top of the conical plate 38 by welding.

[0033] When it rains, the rainwater entering the interior of the device through the gaps between the diversion devices 7 will fall on the top of the conical plate 38, and will be blocked by the annular flow blocking plate 39 during the downward sliding process, so that the rainwater can be temporarily retained on the top of the conical plate 38. On the one hand, it can prevent the gaps between the diversion vanes 71 of the device from being too large on rainy days, resulting in rainwater directly dripping into the interior of the construction site. On the other hand, after the rain stops, the accumulated water on the top of the conical plate 38 can evaporate into the air and mix with the dust-containing air discharged therefrom, so that part of the dust can combine with water vapor and settle, reducing the impact of dust on the environment.

[0034] It can be understood that in the case of natural wind, the natural wind will drive the diversion device 7, so that the diversion device 7 can rotate rapidly on the support device 3 through the support shaft 4 and the rotating device 5, so as to form a rapid air flow at the flow hole Ⅰ2, and then drive the air inside the construction site to flow outwards through the conical plate 38 and the flow hole Ⅰ2. During the flowing process, the water vapor at the conical plate 38 will also be mixed in, thereby reducing the dust concentration; at the same time, the rotating device 5 will also synchronously drive the air circulation pipe 54 to start rotating, and then drive the fan blades 55 inside the air circulation pipe 54 to start rotating. During the rotation of the fan blades 55, a downward air flow will be formed in the air circulation pipe 54 to introduce fresh air from the outside into the interior of the construction site, further improving the air quality of the construction site;

[0035] In addition, when it rains, a small part of the raindrops will enter the interior of the device through the gaps between the diversion devices 7 and fall on the top of the conical plate 38, and will be blocked by the annular flow blocking plate 39 during the downward sliding process, so that the rainwater can be replenished on the top of the conical plate 38; there is also a small part of the raindrops that will fall into the air circulation pipe 54, and this part of the raindrops will pass through the multiple rotating fan blades 55 inside the air circulation pipe 54 from top to bottom. During this process, the raindrops are broken up multiple times to form finer water droplets and then enter the interior of the construction site. This part of the finer water droplets will combine with the dust in the air and settle, which helps to improve the air quality of the construction site and reduce the impact of dust on the surrounding environment and the health of construction workers.

[0036] A travel hole Ⅰ53 is formed at the top of the connection base 52. A travel device 6 is installed at the top of the rotating device 5. The travel hole Ⅰ53 is matched with the travel device 6 in a sliding fit manner. The travel device 6 includes a connection bracket 61. A rain storage tank 62 is fixedly installed at the bottom of the connection bracket 61. A contact rod 65 is fixedly installed at the bottom of the rain storage tank 62. A travel rod 63 is fixedly installed inside the connection bracket 61. A support spring 64 is clamped on the travel rod 63. The travel rod 63 is connected to the top of the connection base 52.

[0037] Further, please refer to Figures 7 - 12 , the travel device 6 includes a connection bracket 61. A rain storage tank 62 is fixedly installed inside the connection bracket 61 by welding. A travel rod 63 is fixedly installed at a position near the inner circle at the bottom of the connection bracket 61 by welding. The travel rods 63 are distributed in a circular array. A support spring 64 is fixedly installed at a position outside the travel rods 63 at the bottom of the connection bracket 61 by clamping. The bottom of the support spring 64 is connected to the top of the connection base 52 by clamping. The support spring 64 is movably installed inside the travel hole Ⅰ53 in a telescopic fit manner. A contact rod 65 is fixedly installed at the bottom of the rain storage tank 62 by welding. The contact rods 65 are distributed in a circular array.

[0038] Further, please refer to Figures 1 - 3 and Figures 7 - 14 , the contact rod 65 is located directly above the travel hole Ⅱ59 in the initial state.

[0039] It can be understood that in rainy days, the rainwater will fill the inside of the rain storage tank 62, increasing the self-weight of the travel device 6 and causing the whole to move downward. Since the contact inclined plate 74 is located directly below the travel hole Ⅱ59 in the initial state, and the contact rod 65 is located directly above the travel hole Ⅱ59 in the initial state, when the travel device 6 moves downward as a whole, the contact rod 65 will insert into the travel hole Ⅱ59 and contact and press against the top of the contact inclined plate 74. During this process, the force received by the contact inclined plate 74 causes the guide vanes 71 to rotate inward and reduces their opening angle, thereby reducing the gap between the guide vanes 71 and preventing a large amount of rainwater from entering the construction site through the gap between the guide vanes 71.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
