Description

Electric spark detector convenient to adjust Technical Field The utility model relates to the technical field of electric spark detection, in particular to an electric spark detector convenient to adjust. Background The electric spark detector is widely applied to defect detection of a coated workpiece (such as a pipeline anti-corrosion layer), and the principle is that a high-voltage electric brush is used for scanning the surface of the workpiece, and when the coating has defects such as pinholes, cracks and the like, electric sparks are generated between the electric brush and a matrix and an alarm is triggered. However, in the traditional electric spark detector, the angle of the electric brush bracket is fixed, the electric brush bracket is difficult to adapt to complex curved surfaces or narrow areas, the bracket needs to be frequently and manually adjusted, the operation is complex, and meanwhile, the position needs to be manually recorded after the defect is detected, so that omission or errors are easy to occur. In addition, since the brushes currently have two shapes and structures, when the brushes are required to be manually replaced according to different detection operation demands, the detection operation efficiency is reduced. Disclosure of Invention The utility model aims to solve the technical problem of providing an electric spark detector convenient to adjust, which can realize the purpose of rapid adjustment and mark defects in real time in the detection process so as to facilitate the follow-up maintenance and treatment operation. In order to solve the technical problems, the technical scheme adopted by the utility model is that the electric spark detector convenient to adjust comprises a host machine, wherein a buzzer module is arranged in the host machine, and an electric brush on the host machine and an electric brush bracket is connected through a probe wire, and the probe wire penetrates into a handle rod to be arranged; The electric brush bracket comprises a fixing part in the middle and movable parts arranged on two sides of the fixing part, connecting rods are arranged on two sides of the fixing part, and the connecting rods are inserted into holes formed in the side edges of the movable parts. In the preferred scheme, a plurality of fixed joints are further arranged between the handle rod and the holder joint. In the preferred scheme, the upper end of handle pole and the lower extreme of cloud platform festival all are equipped with the threaded connection groove, and the section both ends are equipped with the threaded connection post, cooperation between threaded connection post and the threaded connection groove realizes fixed connection. In the preferred scheme, the bottom of the threaded connecting groove and the top of the threaded connecting column are respectively provided with a contact piece, and a probe wire extending into the handle rod is connected to the contact pieces in the threaded connecting groove at the upper end of the handle rod; The contact pieces at the upper end and the lower end of the fixed joint are connected through a wire; and the contact piece in the threaded connecting groove at the lower end of the holder joint is connected with the electric brush on the electric brush bracket through a wire. In a preferred scheme, the brush bracket is provided with an ink gun. In a preferred scheme, the handle rod is provided with an inclinometer. In the preferred scheme, a limiting plate is arranged on a connecting rod part positioned in the side hole of the movable part, and a spring is sleeved on the connecting rod part between the limiting plate and the hole bottom.
