The installation process of the wind power rotating automatic lifting type sand blocking fence of the embodiment is as follows: firstly, the rotating shaft 320 of the rotary sand control net 300 is sleeved into the connecting cylinder 220 of the connecting piece 200 and is arranged at a specified position in rows and intervals; the tip of the long rod body 110 is inserted into the sand surface through the hollow column 210 until reaching the designed buried depth, so as to ensure the stability during operation.
The working principle of the wind-driven rotating automatic lifting type sand-blocking fence of the embodiment is as follows: the wind moving by the sand flow has two characteristics, namely, the wind power is larger and is larger than or equal to the critical sand-raising wind speed, and the wind speed is larger from the ground surface to the air due to the influence of the roughness of the ground surface, namely, the wind speed gradient exists from the ground surface to the air, namely, the wind speed at the ground surface is the smallest, and the wind speed is larger upwards. Under the action of such wind, the rotary sand control net 300 may rotate due to uneven force applied from top to bottom, and the supporting point during rotation is a section of the rotary shaft 320 sleeved in the connecting cylinder 220. In the rotation process of the rotary sand control net 300, the cross-shaped rotary sand control net 300 formed by the four sand control net bodies 310 can intercept most of wind sand like a fence, so that sand particles are stopped and accumulated at the position; in addition, the rotation of the rotary sand prevention net 300 can also disturb airflow and reduce wind speed, and further enhances the intercepting effect of the wind-driven rotary automatic lifting sand prevention fence on sand particles.
After the wind-driven rotating and automatically-lifting type sand blocking fence is used for a period of time, accumulated sand becomes more, the height of the accumulated sand is increased, and at the moment, the sand surface near the fence can be lifted. This will cause the outer protrusions 330 fixed on the rotary sand control net 300 to periodically collide with the sand surface during the rotation process, so that the rotary sand control net 300 is lifted along with the raising of the ground surface by the vibration effect, and the connecting member 200 for supporting is driven to continuously move upwards, thereby preventing the connecting member 200 from being buried by sand particles, achieving the effect of automatic lifting, and further achieving the purpose of automatically maintaining the optimal sand control effect within the range of the height of the long vertical rod 100.
When the connecting cylinder 220 is lifted to be close to the pole top limiting piece 120, the pole top limiting piece 120 can play a role in preventing the connecting piece 200 from sliding out of the long vertical pole 100, so that the rotary sand prevention net 300 is prevented from being separated from the long vertical pole 100, and the integrity of the wind-driven rotary automatic lifting type sand prevention fence is ensured. At this time, the long rod body 110 can be pulled out from the sand body to the designed buried depth, so that the large automatic lifting range is provided, and the sand blocking function is recovered. The sand-blocking effect can be kept all the time after the above steps are repeated. The purposes of very simple operation and material reutilization are achieved.
On one hand, the wind sand flow has the property of being close to the earth surface, on the other hand, the wind power rotating automatic lifting type sand blocking fence is small and exquisite and can be blown by wind more easily, the whole width of the rotating sand prevention net 300 is between 20 and 40cm, and the connecting piece 200 and the rotating sand prevention net 300 are preferably made of light and thin materials.
It should be noted that this embodiment is a preferred embodiment, and in other embodiments without considering various factors such as cost, the connection between the rotary shaft 320 and the connecting cylinder 220 may be a bearing type to reduce friction when the rotary sand screen 300 rotates, which is beneficial to the rotation of the rotary sand screen 300 when wind blows.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
