Embodiment Construction

[0025] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0026] Such as figure 1 As shown, the detection device for the assembly accuracy of the wind turbine wind turbine shroud and the hub according to the embodiment of the present invention includes a hook 10 and a cylinder 20 .

[0027] refer to figure 1 and figure 2 , the hook 10 is U-shaped, and is fixedly connected with the cylinder body 20 . There are at least two lifting holes 15 on the hook 10, a sling shackle can be installed on the lifting holes 15, and the whole detection device can be lifted by a crane by the sling, and installed on the hub pitch slewing bearing.

[0028] The outer diameter of the cylinder body 20 is the same as that of the blade root, and the number of bolt holes and the pitch circle diameter on the cylinder body flange 21 are consistent with those of the blade root flange. During use, the cylindrical body 20 and the hub pitch sle...

Abstract

The invention discloses a device and method for detecting assembling accuracy of a flow guide cover and a hub of a wind generating set. The device for detecting the assembling accuracy of the flow guide cover and the hub of the wind generating set is provided with a barrel body and a U-shaped lifting hook, the barrel body simulates the root of a vane and is provided with a barrel body flange connected with a variable-pitch rotary support of the hub, one branch portion of the U-shaped lifting hook is fixedly connected to the inner wall of the barrel body, the other branch portion of the U-shaped lifting hook is arranged outside the barrel body, and a lifting hole is formed in the branch portion outside the barrel body. The detection device is used in the detection method for detection. According to the device and method, the detection device can be arranged on the variable-pitch rotary support fast by using the lifting hook, the barrel body is used for actually simulating the root of the vane, the clearance between the flow guide cover and the root of the vane can be visually displayed, and assembling deviation is displayed visually and clearly.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a technology for detecting assembly accuracy of a wind turbine wind deflector and a wheel hub. Background technique [0002] The wind power generating set includes a generator part composed of a rotor and a stator, a hub fixedly connected to the rotating shaft of the rotor, and blades installed on the hub. Under the action of wind force, the blades drive the hub to rotate, and at the same time drive the rotating shaft to rotate, thereby driving the rotor to rotate. The stator is fixed radially relative to the rotor. During the working process, when the rotor rotates, it drives the permanent magnetic poles installed in the rotor to rotate, thereby generating a rotating magnetic field, and through the rotating magnetic field, the cutting motion in the stator winding on the stator generates an electromotive force, thereby converting mechanical energy into electrical energy.
