Working principle:
The device mainly achieves the effects of wind prevention, vibration reduction and capacity expansion by researching how to enhance the maximum wind load capacity of the signal tower and installing a streamline dynamic vibration reduction and vibration reduction device on the original signal tower. The device can reduce the wind load of the signal tower body, inhibit potential wind-induced vibration and improve the safety performance of the signal tower. On the other hand, the device can reduce the visual impact of the signal tower to people and improve the economic benefit.
The wing profile dynamic damping vibration reducer is realized by the following modes: the signal tower 1 is enclosed in the device, which has a streamlined shape with a low drag profile. Aerodynamic profile design plays an important role in this project, and the device is adopted to reduce resistance, and a small resistance coefficient indicates that the aerodynamic resistance of an object under the same scale is small. The device is streamlined, and the whole drag coefficient is minimum, plays key role in the wind load research that reduces of this project, and streamlined rotary system is favorable to the dynamic movement of wing section device, prevents that transverse force from transmitting to on the main tower, and when incoming flow wind passes through the signal tower, the fluid covers whole component, reduces the wind load of body of the tower. The rotational design of the streamlined member enables the device to rotate freely about the tower, facing the incoming wind. At any wind speed and wind direction, it can adjust the direction to present the lowest resistance, lighten the pressure of the bottom structure.
In the aerospace and automotive industries, aerodynamics plays a vital role in the design of vehicles and vehicle accessories. One key design goal is to optimize the shape to achieve the lowest resistance. At the same reynolds number, windward area, the resistance of different shapes is typically quantified using a resistance coefficient (denoted c d). The drag coefficient is a dimensionless quantity, and the lower the drag coefficient is, the lower the aerodynamic drag of the object is.
Drag coefficient c d is defined as
F d is the resistance, by definition the force component in the direction of flow velocity, ρ is the mass density of the fluid, u is the flow velocity of the object relative to the fluid, a is the reference area, which for most objects is the area of the object projected in front.
Objects of different shapes have the same reynolds number and the same reference area, with different drag coefficients.
The cube has a larger resistance coefficient than the sphere, and the streamline has the lowest resistance coefficient, so that the streamline is an ideal shape for reducing resistance, and the streamline is used on the device to reduce wind load, so that the wind resistance of the tower can be greatly reduced by covering the streamline shell 8 on the original signal tower.
Because the wind direction is random, this device's unique rotation design can make it can freely rotate around signal tower pole 1, according to wind vane principle: the head part of the windward direction is closer to the rotating shaft, the tail part is narrow in width and far away from the rotating shaft, and after the wind speed exceeds a certain value, the structural resistance of the windward direction can be overcome, so that the head part of the windward direction is opposite to the incoming wind. The gravity center of the device is controlled at the rotating shaft, and the transverse load (equivalent to the bending moment at the bottom of the signal tower) borne by the signal tower is not additionally increased.
The principles and embodiments of the present invention have been described with reference to specific examples, which are provided to facilitate understanding of the method and core ideas of the present invention; also, it is within the scope of the present invention to be modified by those of ordinary skill in the art in light of the present teachings. In summary, the present description should not be construed as limiting the invention.
