DETAILED DESCRIPTION

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

[0026] See also Figure 1-14 As shown in the figure, this embodiment provides a dust suppression device for construction, please refer to Figure 1-Figure 3, including a roof 1, a flow hole Ⅰ2 is drilled on the top of the roof 1 by a drilling machine, a support device 3 is fixedly installed at a position corresponding to the flow hole Ⅰ2 on the top of the roof 1 by a clamping method, a support shaft 4 is movably sleeved on the outer surface of the support device 3 near the top by a bearing connection, a rotating device 5 is placed on the top of the support shaft 4, a travel device 6 is movably installed on the top of the rotating device 5 by a sliding fit, a guide device 7 is movably sleeved on the bottom of the rotating device 5 by a shaft hole fit, and the bottom of the guide device 7 is movably sleeved with the flow hole Ⅰ2,

[0027] During the rotation of the device, the air inside the construction site will flow from the inside to the outside of the construction site under the drive of the guide device 7. At the same time, the 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] For further information, see Figure 1-Figure 3 and Figure 7-Figure 9 The 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 Figure 1-Figure 6 and Figure 10-Figure 14The guide device 7 includes a guide plate 71, and an upper pad 72a and a lower pad 72b are fixedly installed on the top and bottom of the guide plate 71 near one end by welding, respectively. An upper connecting shaft 73 is fixedly installed on the top of the upper pad 72a near one end by welding, and the upper connecting shaft 73 is movably sleeved with the connecting hole II58 by means of shaft hole matching. A contact inclined plate 74 is fixedly installed on the top of the upper pad 72a by welding, and a lower connecting shaft 75 is fixedly installed on the bottom of the lower pad 72b near one end by welding, and the lower connecting shaft 75 is movably sleeved with the connecting hole I37 by means of shaft hole matching. The guide plate 71 is prone to damage in extremely bad weather. In traditional equipment, the guide plate 71 and the overall structure are integrated into one design, which makes it difficult to replace when it is damaged. In the present application document, when the guide plate 71 is damaged, the guide plate 71 is easily damaged in extremely bad weather. In the conventional equipment, the guide plate 71 and the overall structure are integrated into one design, which makes it difficult to replace when it is damaged. In the present application document, when the guide plate 71 is damaged, the guide plate 71 is fixedly installed on the top of the upper pad 72a by welding, and the upper connecting shaft 73 is movably sleeved with the connecting hole II58 by means of shaft hole matching. If the blade 71 is damaged, the rotating device 5 can be directly removed as a whole, so that the guide device 7 can be disassembled as a whole, ensuring that the device can be in the best operating state, improving the maintenance difficulty of the device, and reducing the use cost of the device. The top of the upper connecting shaft 73 is fixedly installed with a reset spring 76 by a snap-on method, and the top of the reset spring 76 is connected to the top of the connecting hole II58 by a snap-on method, so that the guide device 7 as a whole can rotate with the axis of the upper connecting shaft 73 and the lower connecting shaft 75 as the rotation center, so that when the guide blade 71 is in the headwind, the airflow acts on the headwind surface of the guide blade 71 and drives the device to rotate, and also causes the upper connecting shaft 73 and the lower connecting shaft 75 to rotate, thereby increasing the deployment angle of the guide blade 71 and increasing its area of ​​action with the wind, thereby generating a greater torque and improving its ventilation efficiency.

[0030] For further information, see Figure 7-Figure 9 and Figure 13-14 , the contact inclined plate 74 is located directly below the stroke hole II 59 in the initial state.

[0031] For further information, see Figure 1-Figure 6 and Figure 13-14 The support device 3 includes a mounting pad 31, a flow hole II 32 is drilled on the top of the mounting pad 31, a connecting plate 33 is fixedly installed inside the flow hole II 32 by welding, a supporting 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 a bearing connection, a limiting sleeve 35 is fixedly installed on the top of the mounting pad 31 at a position outside the flow hole II 32 by welding, a rotating sleeve 36 is sleeved on the top of the limiting sleeve 35 by rotational cooperation, a connecting hole I 37 is drilled on the top of the rotating sleeve 36 by a drilling machine, the connecting holes I 37 are distributed in a ring array, and the connecting holes I 37 are movably sleeved with the bottom of the guide device 7.

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

[0033] When it rains, rainwater enters the interior of the device through the gaps between the guide devices 7, and then falls on the top of the conical plate 38. During the downward movement, it is blocked by the annular baffle 39, so that the rainwater can temporarily remain on the top of the conical plate 38. On the one hand, it can prevent the gaps between the guide plates 71 of the device from being too large on rainy days, causing rainwater to drip directly 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 the water vapor to settle, reducing the impact of dust on the environment.

[0034] It is understandable that, in the presence of natural wind, the natural wind will drive the guide device 7, so that the guide device 7 can rotate rapidly on the support device 3 through the support shaft 4 and the rotating device 5, so that a rapid airflow is formed at the flow hole Ⅰ2, thereby driving the air inside the construction site to flow to the outside through the conical plate 38 and the flow hole Ⅰ2. During the flow, 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, thereby driving the fan blades 55 inside the air circulation pipe 54 to start rotating. During the rotation of the fan blades 55, a downward airflow will be formed in the air circulation pipe 54, and the external fresh air will be introduced into the interior of the construction site, further improving the air quality of the construction site;

[0035] In addition, when it rains, a small portion of raindrops will enter the interior of the device through the gaps between the guide devices 7, and will fall on the top of the conical plate 38. During the downward movement, they will be hindered by the annular baffle 39, so that the rainwater can be replenished on the top of the conical plate 38. A small portion of raindrops will fall into the air circulation pipe 54, and these raindrops will pass through the multiple rotating fan blades 55 in the air circulation pipe 54 from top to bottom. In this process, the raindrops are broken up many times to form finer water droplets and then enter the interior of the construction site. These fine water droplets will combine with the dust in the air and settle, which will help 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 provided on the top of the connecting seat 52, and a travel device 6 is installed on the top of the rotating device 5. The travel hole I53 cooperates with the travel device 6 by sliding fit. The travel device 6 includes a connecting bracket 61, and a rain storage groove 62 is fixedly installed at the bottom of the connecting bracket 61. A contact rod 65 is fixedly installed at the bottom of the rain storage groove 62. A travel rod 63 is fixedly installed inside the connecting bracket 61, and a support spring 64 is clamped on the travel rod 63. The travel rod 63 is connected to the top of the connecting seat 52.

[0037] For further information, see Figure 7-Figure 12 The travel device 6 includes a connecting bracket 61, a rain storage groove 62 is fixedly installed inside the connecting bracket 61 by welding, a travel rod 63 is fixedly installed at a position near the inner circle at the bottom of the connecting bracket 61 by welding, and the travel rods 63 are distributed in a circular array, a support spring 64 is fixedly installed at a position outside the travel rod 63 at the bottom of the connecting bracket 61 by snap-fitting, the bottom of the support spring 64 is connected to the top of the connecting seat 52 by snap-fitting, and the support spring 64 is movably installed inside the travel hole I 53 by telescopic cooperation, and a contact rod 65 is fixedly installed at the bottom of the rain storage groove 62 by welding, and the contact rods 65 are distributed in a circular array.

[0038] For further information, see Figure 1-Figure 3 and Figure 7-Figure 14 In the initial state, the contact rod 65 is located directly above the stroke hole II 59.

[0039] It is understandable that on rainy days, rainwater will fill the interior of the rain gutter 62, increasing the deadweight of the stroke device 6 and causing it to move downward as a whole. Since the contact ramp 74 is initially located directly below the stroke hole II 59, and the contact rod 65 is initially located directly above the stroke hole II 59, the contact rod 65 will be inserted into the interior of the stroke hole II 59 during the downward pressure of the stroke device 6 as a whole, and will contact and squeeze the top of the contact ramp 74. During this process, the force applied to the contact ramp 74 causes the guide vane 71 to rotate inward and reduce its deployment angle, thereby reducing the gap between the guide vanes 71 and preventing a large amount of rainwater from entering the interior of the construction site through the gap between the guide vanes 71.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
