Problems solved by technology

[0004] The purpose of the present invention is to provide an all-round testing equipment for hidden cracks in fan blades to solve the problem that the traditional fan blade testing equipment proposed in the background technology does not isolate external interference when testing cracks, which may cause inaccurate testing results. Accurate, and at the same time, it cannot be easily dealt with the problem of extremely fine hidden cracks

Abstract

The invention discloses an omnibearing test device for hidden cracks of fan blades, which comprises a test main body, a first groove is formed in the inner surface wall of one side of the test main body, a flash shell is fixedly arranged in the first groove, and a plurality of flash pulse lamps are fixedly mounted on the outer surface wall of one side of the flash shell. An infrared detector is fixedly arranged in the first groove, a shading mechanism is fixedly arranged between the inner surface walls of the two sides of the testing main body, a repairing mechanism is fixedly connected to the top of the testing main body, and lantern rings are fixedly installed at the positions, close to the four corners, of the top of the repairing mechanism; according to the scheme, the problems that when existing fan blade testing equipment is used for detecting cracks, external interference is not isolated, so that the detection result is possibly inaccurate, and meanwhile, extremely fine implicit cracks cannot be simply treated are solved.

Description

technical field [0001] The invention relates to the technical field of fan blades, in particular to an all-round testing device for hidden cracks in fan blades. Background technique [0002] The fan blade is one of the core components of the wind power generator. Its quality will directly affect the performance and benefit of the fan. The fan blade has high requirements on the material. It not only needs to have a lighter weight, but also needs to have a higher strength. , corrosion resistance, and fatigue resistance, so current fan manufacturers widely use composite materials to manufacture fan blades. [0003] However, the existing fan blades have the following problems during use: when the fan blades are used for a long time, they may collide with sand and gravel in the air, causing cracks on the surface and affecting the overall operation of the fan blades. It needs a special person to detect it. However, some small cracks are difficult to detect with the naked eye, so ...
