Automatic telegraph pole anti-shake device based on Bernoulli principle
According to the automatic telegraph pole anti-shaking device based on the Bernoulli principle, the function of providing a power source for vertical lifting is achieved through a fixed type vertical lifting mechanism; shaking caused by wind power is reduced through a flow velocity difference windproof mechanism; connection and power transmission of the two mechanisms are achieved through the lifting rope. By means of the Bernoulli principle, when natural wind penetrates through the wing type pressure difference ventilation plates in the device, pressure formed by air pressure difference can be generated, the wind power is further weakened through the resultant force of the pressure, and the problem that the telegraph pole shakes due to the fact that the windward stress of the telegraph pole is too large is solved.
本发明提出了一种基于伯努利原理的电线杆自动防抖装置，本装置通过固定式垂直升降机构，实现提供垂直升降的动力源的功能；通过流速差防风机构，减小风力带来的抖动；通过升降绳索，实现两个机构的连接和动力传递；本发明通过利用伯努利原理，当自然风穿过装置中的机翼式压差通风板时，会产生由气压差形成的压力，进一步通过压力的合力削弱风力，解决了电线杆迎风受力过大带来的电线杆晃动问题。
