A waveguide inspector for internal inspection of multi-curve waveguide

Abstract

The invention provides a waveguide tube detector for detecting the interior of a multi-curve waveguide tube. The waveguide tube detector consists of a reinforced notebook computer, a control box, an image signal cable, an operating handle, a detection insert tube and a comprehensive signal cable, wherein the detection insert tube consists of a cuboid, an optical fiber cable, a stainless steel spring, a stainless steel wire rope and an insert tube head; the stainless steel spring and the stainless steel wire rope are arranged in the interiors of the cuboid and the insert tube head up and down in a penetrating manner, and the cuboid and the insert tube head are connected with each other by the stainless steel spring and the stainless steel wire rope to form an integrated elastic detection insert tube. According to the waveguide tube detector for detecting the interior of the multi-curve waveguide tube, which is disclosed by the invention, by utilizing the elastic-force-based elastic detection insert tube, the technical problems of field non-destructive detection on the interior of the multi-curve waveguide tube are solved; furthermore, by utilizing devices with ultralow power consumption, the waveguide tube detector has the advantages that the power consumption is low, the operation is simple and convenient, the operation is reliable, and the detection diagnosis data is precise; the waveguide tube detector disclosed by the invention can be widely applied to field detection diagnosis on internal surface defects of a small-aperture multi-curve waveguide tube, and in particular to the field detection diagnosis on the internal surface defects of a small-aperture rectangular multi-curve waveguide tube.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to a non-destructive testing device for diagnosing internal defects of small-diameter waveguides. Background technique [0002] In the elastic structure waveguide inspection instrument, the elastic inspection insertion tube can complete the inspection of the multi-bend waveguide without hindrance and damage, so as to obtain the image information of the internal defect of the object to be inspected. The waveguide is the only "channel" for transmitting high-frequency energy in the radar high-frequency system, and its working condition is directly related to the strength of the radar capability. Its internal diameter is small, and only the inner surface has high smoothness and good coating consistency. Only the waveguide can realize the normal transmission of the internal electromagnetic wave signal, and when a defect occurs inside the waveguide, the electromagnetic wav...
