A wind speed measurement structure

Abstract

The invention discloses an anemometer structure, which relates to the technical field of anemometers. The key point of the technical solution is to include a measuring device, which includes a base, a cover and a plurality of anemometers; each anemometer includes a fan and a test host; A plurality of first horizontal plates are fixedly connected to the inner peripheral surface, and a connecting block is fixedly connected to one side of each fan housing, and the connecting block is slidably connected to one side of the first horizontal plate; a driving mechanism is installed in the base; the driving mechanism It includes a support plate, a first lead screw, a drive block, and a drive assembly installed on the base for driving the first lead screw to rotate; each connecting block and the drive block are respectively provided with a first slope on the inner side, and the support plate is installed for A guide assembly for guiding the drive block, a first reset assembly for driving the connection block to reset is installed on the first horizontal plate. The invention facilitates simultaneous measurement of a plurality of measurement points by arranging the measurement device, thereby improving the measurement accuracy of the wind speed at the tuyere.

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)
