Wind tunnel testing device for wind load of arc-shaped conductor

Abstract

The invention discloses an arc conductor wind load wind tunnel test device which comprises a base fixedly connected to the ground, a rotating opening is formed in the upper end face of the base, a rotating disc is rotationally connected in the rotating opening, the rotating opening is arranged in a T shape, the shape of the rotating disc is matched with that of the rotating opening, and the rotating disc is arranged in the rotating opening. A rotating base is fixedly connected to the side wall, away from the ground, of the rotating disc, two symmetrically-arranged adjusting devices are fixedly connected to the side wall, away from the base, of the rotating base, the two adjusting devices are arranged away from each other, and each adjusting device comprises a rotating groove formed in the side wall, away from the base, of the rotating base; a rotating block is rotationally connected into the rotating groove, and the rotating groove is in a T shape. According to the invention, the installation work of arc-shaped wires with different heights and widths can be conveniently completed, the angle between the arc-shaped wires and the wind direction can be conveniently adjusted, and different test requirements of users are greatly met.

Description

technical field [0001] The invention relates to the related technical field of wind tunnel testing, in particular to a wind tunnel testing device for wind load of arc-shaped conductors. Background technique [0002] Wind tunnel experiment refers to an aerodynamic experimental method that places an aircraft or other object model in a wind tunnel to study the flow of gas and its interaction with the model to understand the aerodynamic characteristics of the actual aircraft or other objects. Complete the test work of various objects, such as the wind load test work of the arc wire.

Problems solved by technology

[0003] When the existing arc-shaped wires are tested for wind load in the wind tunnel, the corresponding brackets are mainly used to fix the arc-shaped wires, and then the corresponding wind tunnel experiments are carried out. However, this installation method makes it impossible for users to adjust the arc shape conveniently. The height of the wire and the distance between the fixed points at both ends of the arc wire are very inconvenient for the user to work. At the same time, the user also partially adjusts the relative angle between the arc wire and the wind direction in the wind tunnel, which is also not conducive to the user's various experimental work.
