Wind speed measuring structure

Abstract

The present invention discloses a wind speed measuring structure, pertaining to the technical field of anemometers. The structure comprises a measuring device. The measuring device comprises a base, acover body, and multiple anemometers. Each anemometer comprises fans and a test host. The inner peripheral surface of the base is fixedly connected with multiple first horizontal plates, one side ofthe shell body of each fan is fixedly connected with a connecting block, and each connecting block is slidably connected to one side of the corresponding first horizontal plate. The base is provided with a driving mechanism. The driving mechanism comprises a support plate, a first lead screw, a driving block and a driving component arranged at the base and used for driving the first lead screw torotate. The opposite inner side of each connecting block and the driving block is provided with a first inclined surface separately, the support plate is provided with a guiding component used for guiding the driving block, each first horizontal plate is provided with a first reset component used for driving the corresponding connecting block. According to the structure, by arranging the measuringdevice, the measurement on multiple measuring points is convenient at the same time, and thus the measuring precision of the wind speed of a wind gap is improved.

Description

technical field [0001] The invention relates to the technical field of anemometers, more specifically, it relates to an anemometer structure. Background technique [0002] An anemometer is an instrument that measures air velocity. There are many types of it, and the most commonly used one in meteorological stations is the wind cup anemometer, which consists of three parabolic cone empty cups fixed on the bracket at 120° to each other to form the sensing part, and the concave surfaces of the empty cups are all in one direction. The whole induction part is installed on a vertical rotating shaft, and under the action of wind force, the wind cup rotates around the shaft at a speed proportional to the wind speed. Anemometers are capable of measuring the velocity and direction of the average flow, measuring the pulsating velocity of the incoming flow and its frequency spectrum. Measure the Reynolds stress in turbulent flow and the velocity dependence and time dependence of two p...

Problems solved by technology

[0004] However, the above-mentioned equipment needs to move the fan to measure different points of the tuyere when measuring, because the measurement personnel may sometimes measure one measurement point twice when measuring through the fan, so the measurement accuracy of the wind speed at the tuyere may be inaccurate. High (existing wind speed measurement: by measuring multiple measurement points of the tuyere, and then taking the average value)
