Problems solved by technology

[0002] Most of the existing test tunnels used for testing generators have an integral structure. The test tunnels are long and occupy a large space, and the existing wind turbine test tunnels cannot adjust the size of the tunnel air outlet. If you want to change the wind The flow rate can only be achieved by changing the power of the blower. Using a high-power blower consumes a lot of power, and when replacing a different blower, the tunnel needs to be disassembled, which is very cumbersome to use
In addition, when the fan in the existing test tunnel is working, the vibration generated by the fan is directly transmitted to the tunnel. If things go on like this, it will cause wear at the junction of the tunnel and damage the tunnel

Abstract

The invention discloses a tunnel assembly for wind driven generator testing. A first air duct and a third air duct are fixedly connected with the two ends of a second air duct correspondingly, and aresupported to a first supporting frame and a third supporting frame correspondingly; the second air duct is fixedly connected with a fixed frame; an air blowing installing frame is fixed in an inner cavity of the second air duct; a motor is fixed to the air blowing installing frame; an output shaft of the motor is fixedly connected with a fan; a wind speed adjusting ball is rotationally connectedinto an inner cavity of the third air duct; and a power generator is arranged on one side of the third air duct. By means of the tunnel assembly for wind driven generator testing, the flow speed of wind can be adjusted, the using condition of the power generator under different wind speeds is tested, the air blowing installing frame can effectively relieve vibration generated during operation of the motor, it is avoided that the vibration of the motor is directly transmitted to the second air duct, and therefore the abrasion disjoin phenomenon, caused by the vibration, of the joint of the second air duct and the first air duct and the joint of the second air duct and the third air duct is avoided, and the service life of a tunnel is prolonged.
