Multifunctional integrated wind factor verification device

Abstract

The invention discloses a multifunctional integrated wind factor verification device. The device comprises an outer frame, a down-blowing wind tunnel and a control system, wherein the down-blowing wind tunnel and the control system are mounted in the outer frame; the outer frame is provided with a bracket and an outer wall plate mounted on the bracket, one end of the outer frame is provided with an air inlet, and the other end of the outer frame is provided with a transparent standing chamber. By blowing a power section into the down-blowing wind tunnel, compared with an air suction mode, thedevice has the advantages that reduction of the occupied area of wind tunnel equipment is facilitated and has no special requirement for the field, and the manufacturing cost is reduced. A frequency converter of the control system is connected with the power section to better control the power section, and therefore the stable airflow flowing demands are met.

Description

technical field [0001] The invention relates to a multifunctional integrated wind element verification device, in particular to a multifunctional integrated wind element verification device capable of testing instruments under low wind speed or high wind speed conditions. Background technique [0002] In the existing meteorological field, the verification device used to calibrate the wind direction and wind speed of the anemometer is usually a traditional large-scale loop wind tunnel, but the wind tunnel occupies a large area, and when measuring the wind sensor, it is usually impossible to maintain the flow at low wind speeds. stability and uniformity. [0003] There is a wind tunnel system simulated in a self-priming mode environment, which is used to improve the deficiency of the verification device of the loop wind tunnel. In order to form a gas flow path, the motor drive is set near the resident room. Since the motor drive is located in the resident room The airflow gen...

[0002] In the existing meteorological field, the verification device used to calibrate the wind direction and wind speed of the anemometer is usually a traditional large-scale loop wind tunnel, but the wind tunnel occupies a large area, and when measuring the wind sensor, it is usually impossible to maintain the flow at low wind speeds. Stability and Uniformity

[0003] There is a wind tunnel system simulated in a self-priming mode environment, which is used to improve the deficiency of the verification device of the loop wind tunnel. In order to form a gas flow path, the motor drive is set near the resident room. Since the motor drive is located in the resident room The airflow generated may be unstable, so it is necessary to improve the structure of the air duct, for example, adding a part of the stabilizer in the middle, thus, it is also impossible to reduce the volume of the wind tunnel smaller, and this kind of wind tunnel is not easy Control the stability of the airflow
