Description

Pipeline endoscope Technical Field The invention belongs to the technical field of video detection, and particularly relates to a pipeline endoscope. Background The pipeline endoscope is mainly used for detecting video in the pipeline, the condition of pipeline blockage can be frequently encountered in the video detection process, and especially for the pipeline with smaller diameter, the video detection can not be carried out at the moment, additional equipment is needed for dredging the pipeline, and often detection staff can not carry pipeline dredging equipment with him or carry the dredging equipment at the same time, so that the labor cost is increased, the condition of pipeline blockage occurs, additional time is spent, and the working efficiency is reduced. If the pipeline endoscope has the pipeline dredging function, the common problem in the video detection process can be solved, and the problem of better fusion of the dredging structure and the original structure of the pipeline endoscope is solved, so that the operation of detecting the video and dredging the pipeline is not affected mutually, and the pipeline dredging method is a key for solving the pipeline dredging problem. Accordingly, it is necessary to provide a pipeline endoscope having a dredging mechanism capable of dredging a blocked pipeline and simultaneously being compatible with an existing pipeline detection structure, and not interfering with each other in the respective independent operation processes. Disclosure of Invention The invention aims to provide a pipeline endoscope which solves the defect that the pipeline endoscope in the prior art cannot dredge a pipeline. In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: The pipeline endoscope comprises a main control box, a signal cable, a first rotary table and a camera, wherein one end of the signal cable is connected with the main control box, the other end of the signal cable is connected with the camera, and the signal cable is fixed on the first rotary table. Further, the signal cable is disposed inside the coil. The signal cable is arranged inside the coil, so that the space occupied by the pipeline endoscope is saved, and the pipeline endoscope is convenient to use and store. The dredging head comprises a connecting rod, a steel chain and two ends, wherein two ends of the connecting rod are respectively connected with one end, and two ends of the steel chain are respectively connected with one end. Further, the steel chain is formed by connecting a plurality of buckles. In the invention, the coil comprises a steel core and an outer cladding layer sleeved outside the steel core, so that the steel core can move in the outer cladding layer. The steel core is protected through the outer cladding layer, is not easy to break, has the characteristic that a very high pipeline turns, and is convenient to dredge. Further, the motor is in transmission connection with the claw disc, and the claw disc is fixedly connected with the inner steel core of the coil, so that the motor drives the inner steel core of the coil to rotate through claw disc transmission. In the invention, the dredging mechanism further comprises a limiter, and the limiter is sleeved outside the coil and used for limiting the moving range of the coil. The adoption of the limiter can prevent the coil from winding, and is not easy to lead out and drop. Further, the limiter comprises a main body and a positioning buckle; the coil outer wrapping layer is fixedly provided with a positioning block, and the coil is matched with the limiting groove through the positioning block to realize the limiting of the coil outer wrapping layer by the limiter. Through setting up like this, the locating piece of cable is directional blocks into in the spacing groove, can realize in the coil outer sheath layer spacing when the mediation for the steel core rotates the activity, and outer sheath layer is motionless, avoids cable outer sheath layer and steel core to rotate simultaneously, causes the injury to operating personnel hand. Further, the channel in the main body is a transition channel with a height difference, and the outlet height of the channel close to the channel opening at one end of the motor is higher than the outlet height of the channel opening close to one end of the dredging head. By means of the design, stress is reduced when the coil is pulled out, service life of the product can be prolonged, and convenience in use can be improved. In the invention, a conductive slip ring component is fixed on the axis of the second turntable, and the conductive slip ring component is connected with a motor of the dredging mechanism through a power line. By using the conductive slip ring assembly, the power line is led out from the axis of the turntable to supply power to the dredging mechanism, thereby avoiding the power line from being twisted off due to long-term rotation and pro
