Problems solved by technology

[0003] During routine measurement, some air turbulence often occurs in the wind tunnel. When such turbulence passes obliquely through the fan of the air meter, it will affect the measurement accuracy of the air meter. The conventional part of the air meter fixing device that can change the measurement angle is often Fix the wind meter at an angle that is conducive to measurement, but there are still some measurement errors

Abstract

The invention discloses a fixing device for a detection electronic air speed gauge of a mine. The fixing device comprises a bottom plate, a vertical pipe, a sliding column, a rotating ring, a wind rudder, a connecting column, a metal hoop and a balance shaft, wherein the outer contour of the bottom plate is of a round shape, bottom holes in the annular array are formed in the bottom plate, the vertical pipe is welded to the bottom plate, the sliding column is located inside the vertical pipe, a middle bearing is fixed at the top of the sliding column, a ring column is inserted into the middlebearing, the rotating ring is welded above the ring column, a top bearing is installed inside the rotating ring, the connecting column is located inside the rotating ring, a counter bore and a threaded hole are formed in the connecting column, a threaded part of a rotating bolt is located in the threaded hole, a shaft body of the rotating bolt is located inside the top bearing, the two ends of thebalance shaft are in threaded connection with a rudder frame and a bent shaft, the wind rudder is welded on the rudder frame, and the metal hoop is welded to one end, far away from the threads, of the bent shaft. According to the fixing device for the detection electronic air speed gauge of the mine, the air speed gauge can be always made to face the air flow of an air hole, the measurement precision is improved conveniently, and the device is suitable for being widely popularized and used.

Description

technical field [0001] The invention belongs to the technical field of wind meters, in particular to a fixing device for detecting mine electronic wind meters. Background technique [0002] The mine electronic anemometer is one of the important components of the mine underground monitoring and monitoring system. The underground ventilation status is transmitted to the monitoring and monitoring system through the impeller, wind cup or sensor, so that the underground ventilation status can be accurately understood. Its accuracy is directly related to the safety of underground production in various industries. [0003] During routine measurement, some air turbulence often occurs in the wind tunnel. When such turbulence passes obliquely through the fan of the air meter, it will affect the measurement accuracy of the air meter. The conventional part of the air meter fixing device that can change the measurement angle is often Fix the wind meter at an angle that is conducive to m...
