Embodiment 1

[0011] Embodiment 1, with reference to figure 1 . A blade rotating device for comprehensive performance testing of fan blades, which includes a fixed base 3, a worm drive system 5, a slewing bearing 4 and a rotor locking disc 2; the slewing bearing 4 is installed on the fixed pedestal 3, and the The rotor locking disc 2 is fixedly connected with the slewing bearing 4, the power output end of the worm drive system 5 is connected with the slewing bearing 4, and both the rotor locking disc 2 and the fixed base 3 are provided with screw holes.

[0012] During the test, the blade 1 to be tested can be fixed on the rotor locking disk 2 through bolts and screw holes, and the slewing bearing 4 is driven to rotate through the worm drive system 5, thereby driving the blade 1 to continuously change the angle; when the blade 1 reaches the required angle Finally, the rotor locking disc 2 is fixed on the fixed base 3 through bolts and screw holes. When using the loading system to load the...

Embodiment 2

[0013] Example 2. In the blade rotating device for comprehensive performance testing of fan blades described in Example 1, the fixed base 3 is composed of two layers of steel plates, the slewing bearing 4 is installed between the two layers of steel plates, and the slewing bearing 4 is fixed by bolts on the back plate.

Embodiment 3

[0014] Example 3. In the blade rotating device for comprehensive performance testing of fan blades described in Embodiment 2, the power output end of the worm drive system 5 passes through the rear steel plate and is connected to the slewing bearing 4 through gear meshing.

Abstract

The invention relates to a blade lade rotating device for a comprehensive performance test of fan blades, which is characterized by comprising a fixed base, a worm driving system, a swing bearing and a rotor locking disk, wherein the swing bearing is arranged on the fixed base, the rotor locking disk is fixedly connected with the swing disk, a dynamic output end of the work driving system is connected with the swing bearing, and the rotor locking disk and the fixed base are both provided with screw holes. The invention conveniently realizes the angle rotation of the blades so blades to be tested are not easy to be damaged during rotation, simultaneously and greatly lightens the design and manufacture difficult of the swing bearing, simplifies the testing process of the comprehensive performance of the blades used by a wind driven generating set, saves the detection cost of the fan blades and enables the scale production of the fan blades with different specifications to be realized; and moreover, the test process is convenient and fast and the test results have strong visual property and high data accuracy.

Description

technical field [0001] The invention relates to a testing device for the comprehensive performance of fan blades, in particular to a blade rotating device for testing the comprehensive performance of fan blades. Background technique [0002] In order to ensure the safe operation of wind turbines, it is necessary to detect the comprehensive performance of the blades of wind turbines. The blades need to be turned over during the test. In the prior art, manual methods are used to flip the blades. Due to the heavy weight, irregular shape and long length of the blades, manual methods will not only make the testing process cumbersome, but also easily damage the blades to be tested. Data loses accuracy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a blade rotating device for comprehensive performance testing of fan blades which has a reasonable structure and ensures accurate and fast testing process. [0004] The ...
