Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of unit fault diagnosis, in particular to unit state fault diagnosis overhauling auxiliary device. BACKGROUND

[0002] The generator set is the complete mechanical equipment that converts other forms of energy into electric energy, which is composed of a power system, a control system, a noise reduction system, a damping system and an exhaust system, driven by a water turbine, a steam turbine, a diesel engine or other power machinery, and converts the mechanical energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy to the generator, and then converts the mechanical energy into electric energy by the generator and outputs to the electric equipment for use. When the generator set fails, various tools need to be used to detect the generator set, among which the ultrasonic flaw detector can detect the generator stator winding, the generator rotor and the metal shell structure of the generator set.

[0003] The application number 202323267344.2 discloses an ultrasonic flaw detector chest support, which comprises a storage box body and an ultrasonic flaw detector main body. A rotating plate is rotatably arranged on the outside of the storage box body through a hinge. A placing groove for placing the ultrasonic flaw detector main body is formed at the top end of the rotating plate. A tight component is arranged on the inside of the placing groove to tightly hold the horizontal position of the ultrasonic flaw detector main body. Limiting components are arranged on both sides of the top end of the rotating plate to limit the vertical position of the ultrasonic flaw detector main body. The application patent binds the storage box body at the waist position in front of the chest through two straps, and then places the ultrasonic flaw detector main body in the placing groove. The ultrasonic flaw detector main body is limited on the rotating plate through the cooperation of the tight plate and the two limiting blocks. At this time, the operator only needs to hold the probe with one hand to perform flaw detection operation on the workpiece, which can reduce the labor intensity of the operator holding the ultrasonic flaw detector main body, and further improve the flaw detection efficiency of the operator.

[0004] Although the above-mentioned application patent can assist to a certain extent when the ultrasonic flaw detector is used, and the labor intensity of the operator holding the ultrasonic flaw detector is reduced. Dust will adhere to the surface of the object to form a layer of barrier, which will hinder the propagation path of ultrasonic waves, change the reflection and refraction behavior of sound waves, and thus affect the accuracy of the flaw detection result. Therefore, before the actual use of the ultrasonic flaw detector, the surface of the detected position needs to be processed to a certain extent, including cleaning the dirty surface and polishing the uneven surface. The above-mentioned application patent cannot provide assistance to the user in these aspects, and it is relatively inconvenient to use. UTILITY MODEL CONTENTS
