A wind tunnel apparatus for multi-flow testing

By combining a drive mechanism and an adjustment mechanism with a worm gear and a two-way threaded rod, the problem that wind tunnel devices can only perform single-angle tests has been solved, enabling multi-angle and multi-directional testing, simplifying operation and improving testing accuracy.

AI Technical Summary

Technical Problem

Existing wind tunnel devices can only test one angle of the object being tested, requiring the addition of adjustment fixtures on the carrier plate, which is cumbersome and inconvenient for multi-angle testing.

Method used

A wind tunnel device including a drive mechanism, an adjustment mechanism, and a limiting mechanism was designed. The motor drives the gear set to rotate the connecting shaft. Combined with the worm gear and the bidirectional threaded rod, it realizes multi-angle and multi-directional testing of the placement platform, and the limiting mechanism stably clamps the object under test.

Benefits of technology

It enables multi-angle and multi-directional testing of the tested object, is easy to operate, and the limiting mechanism does not affect the airflow, resulting in more accurate test results.

Abstract

This utility model discloses a wind tunnel device for multi-flow rate testing, relating to the technical field of wind tunnel devices. It includes a housing and a connecting shaft. One end of the housing is connected to an air inlet, and a filter screen is fixed to one side of the air inlet. A variable frequency fan is installed at the other end of the housing. A base is fixedly connected to the bottom of the housing. Flow stabilizing mesh plates are installed at both ends of the housing. A placement platform is provided in the middle of the housing, and a drive mechanism for rotating the platform is provided at the bottom of the platform. This wind tunnel device for multi-flow rate testing allows the placement platform inside the housing to rotate by activating the drive mechanism, causing the object under test on top of the platform to also rotate, thus enabling multi-directional testing of the object. The angle of the placement platform can be adjusted by an adjustment mechanism, allowing for multi-angle testing of the object. A limiting mechanism at the top of the placement platform provides stable positioning of the object under test.
