Vertical wind measuring frame based on multi-channel anemometer

Abstract

The invention discloses a vertical wind measuring frame based on a multi-channel anemometer. As there is a need to measure the horizontal wind speeds and directions at different heights in the vertical direction in a shelterbelt net for the research on the shelter effect of shelterbelts in forestry, the vertical wind measuring frame is designed especially. The vertical wind measuring frame is composed of a main frame, solid steel rods, a transverse frame, T-shaped screws, a base, U-type semi-rings, T-shaped screws, long steel wire pull fibers, short steel wire pull fibers, U-type clips, and ground nails. The main frame is composed of three sections of steel pipes which are connected by the solid steel rods. The height of the transverse frame can be adjusted randomly. A wind cup and a wind vane can be installed on the transverse frame. The T-shaped screws can be used to fix the transverse frame and the wind cup. The U-type semi-rings, the base, the pull fibers, the U-type clips and the ground nails are used to fix the main frame and prevent the main frame from being blown down by strong wind. The design structure is simple and light, and is easy to use and transport. The height can be adjusted randomly within the total length range of the main frame. The experimental requirement for measurement of wind speed and direction in the vertical direction is satisfied. Convenience is brought to forestry workers. The vertical wind measuring frame can be widely promoted and used.

Description

[0001] (1) Technical field [0002] The invention relates to a special frame for measuring horizontal wind speeds with different gradients in the vertical direction by using a multi-channel anemometer, and especially designs a vertical wind-measuring frame for a multi-channel anemometer. [0003] (2) Background technology [0004] In forestry, in order to measure the wind protection benefits of shelterbelts and study the changes of wind speed and direction in the vertical direction of the shelterbelt network, it is usually necessary to use multi-channel anemometers to measure the horizontal wind speed and direction of different heights on the vertical plane of the shelterbelts for simultaneous observation. Fix 8 wind cups on the same vertical line at different heights, and then connect the host data acquisition device through 8 wires. When fixing the wind cups, a higher shelf is needed to meet the needs of wind speed measurement at different heights. The original The multi-chan...

Problems solved by technology

[0004] In forestry, in order to measure the wind protection benefits of shelterbelts and study the changes in the wind speed and direction of the wind field in the vertical direction in the shelterbelt network, it is usually necessary to use multi-channel anemometers to measure the horizontal wind speed and direction of different heights on the vertical plane of the shelterbelts for simultaneous observation. Fix 8 wind cups on the same vertical line at different heights, and then connect the host data collector through 8 wires. When fixing the wind cups, a higher shelf is needed to meet the needs of wind speed measurement at different heights. The original The multi-channel anemometer company also did not provide a matching elevated rack for its use

In addition, the high wind speed in the field is difficult to fix, and the elevated frame is not easy to transport
