Mining wind speed sensor and correction method thereof

Abstract

The invention discloses a mining wind speed sensor and a correction method thereof. The sensor comprises a mounting barrel, a wind speed sensor main body is arranged in the mounting cylinder; a rotating rod is arranged on the lower end surface of the wind speed sensor main body; a first mounting plate is arranged at the lower end of the rotating rod; a wind cup part is arranged on the first mounting plate. In the mining wind speed sensor and the correction method thereof, a reinforcing rib, a locking nut, a correction box and the like are arranged; the mounting and hanging positions of the mining wind speed sensor are not limited; the wind speed sensor can be conveniently corrected; the measuring accuracy effect is improved, the problems in the prior art that the support is simple in structure, it cannot guarantee that the installation and suspension positions of the wind speed sensor are not limited, and the sensor needs to be corrected to improve the measurement precision, is disassembled and maintained at present, is sent to a laboratory for correction, and is very troublesome in practice are solved.

Description

technical field [0001] The invention relates to the technical field of wind speed sensors, in particular to a mine wind speed sensor and a calibration method thereof. Background technique [0002] The wind speed sensor can continuously monitor the wind speed and air volume (air volume = wind speed x cross-sectional area) of the above locations, and can display the wind speed and air volume of the roadway in real time. It is an important instrument for mine ventilation safety parameters measurement. Its sensor components are composed of wind speed Composed of sensors, wind direction sensors, and sensor brackets, it is mainly used in coal mine ventilation general return lanes, air outlets, main underground wind measuring stations, fan wellheads, tunneling working faces, coal mining working faces, etc. in coal mines where there is a risk of gas explosion. and corresponding mining companies. [0003] Mine-used wind speed sensors are installed under mines, and the installation c...

AI Technical Summary

Problems solved by technology

[0003] Mine-used wind speed sensors are installed under mines, and the installation conditions are complex. The current bracket structure is simple, which cannot guarantee that the installation and suspension position of the wind speed sensor is not limited. At the same time, the wind speed sensor needs to be calibrated to improve its measurement accuracy. The current method is to disassemble and maintain. Sent to the laboratory for calibration, which is very troublesome in practice
