AI Technical Summary

Technical Problem

Endoscopic inspection equipment suffers from a lack of cable restraint at pipe bends, leading to loss of posture, friction damage, excessive bending causing core breakage and short circuits, and connection disconnection, thus affecting the continuity of inspection.

Method used

The system employs positioning components, including guide wheels, connecting plates, winding wheels, and motors. The motor drives the winding wheels to raise and lower the rope, maintaining the wire in a stable, bent state and preventing friction with the inner wall of the pipe. Multiple mechanical structures ensure a stable connection.

Benefits of technology

This effectively avoids cable sheath wear, conductor breakage, insulation layer cracking, and signal interruption, ensuring the continuity and stability of the testing process.

Abstract

The invention relates to the technical field of drainage pipeline detection, and discloses an endoscopic detection device for a drainage pipeline, which comprises a detection assembly and a detection assembly, the detection assembly comprises a walking vehicle, the walking vehicle is provided with a detection head, and the tail part of the walking vehicle is connected with a wire; the positioning assembly is arranged on the wire and comprises a positioning piece, the positioning piece comprises a guide wheel located on the outer side of the wire, a fixing column is fixed in the guide wheel, a connecting plate is rotationally connected to the outer side of the fixing column, a connecting rod is fixed to the top of the connecting plate, and a winding wheel is arranged on the top of the connecting rod. The beneficial effects of the invention are that through the arrangement of the positioning assembly, the cable can be kept in a stable bending state and does not rub with the inner wall of the pipeline, thereby avoiding signal interruption or equipment short circuit caused by wear of an outer sheath of the cable, conductor fracture and cracking of an insulating layer, eliminating the influence of frictional resistance on the connection point of the detection head and the walking mechanism, and improving the detection precision. Detection interruption caused by disconnection of the two is avoided, and the detection process is continuous and stable.
