Embodiment Construction

[0021] see Figure 1 to Figure 5 As shown, it is a multi-functional integrated wind element testing device disclosed in the present invention, which includes an outer frame 1, a down-blowing wind tunnel 2 installed in the outer frame 1, and a control system 5; the down-blowing wind tunnel The tunnel 2 has a power section 3 arranged at the front end of the down-blown wind tunnel and blows airflow (such as natural wind) into the down-blown wind tunnel 2. One end of the outer frame 1 is provided with an air inlet, and the other end is provided with a Transparent chamber 4.

[0022] The outer frame 1 is provided with a plurality of brackets 11, an outer wall plate 12 and an orifice 13 at the front end, and forms a cavity 14 with the air inlet at one end, and the orifice 13 is placed on the air inlet. In this embodiment Among them, the above-mentioned transparent chamber 4 is located outside the cavity, the bracket 11 and the outer wall plate 12 are made of aluminum parts, and the...

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...
