Description

Sightline Camera for Sewage Pipe Survey

The present invention is a device for repairing water and sewage pipelines by non-excavation, and relates to a perspective camera for exploring the situation in the pipeline, and in particular, a sewer pipe that can be rotated in the front and left and right directions to investigate in detail cracks in the inner wall of the pipeline. It relates to a perspective camera.

In general, the domestic water and sewage pipelines have been used to replace or repair the fuse after excavating the ground. However, such reclamation can not be appropriate in the urgent situation of a comprehensive sewer pipeline. In other words, the above method not only damages the surrounding environment, but also causes ground subsidence due to soil erosion after construction, as well as difficulty in disposal of waste, traffic congestion in congested areas, and inconvenience to citizens. There is a problem.

In order to solve the above problems, in recent years, a number of non-excavation methods for repairing sewage pipes without dismantling the road have been developed in accordance with the domestic reality.

This non-excavation process consists of a series of processes including dredging and cleaning of pipelines, CCTV exploration, cutting of protrusions in pipelines, reversal insertion, hot water heat curing, and drilling of connectors.

As the equipment used in the non-excavation method, C.C. The camera displays the situation in the pipe on a monitor installed in an external vehicle so that the operator can easily recognize the situation inside the pipe.

As shown in FIG. 1, a conventional perspective camera includes a main body 101 having wheels 102 attached to both sides thereof, a camera 104 mounted to the front of the main body 101 to detect an inside of a pipeline, and a circumference thereof. A camera head 103 having an illumination 105, a left and right rotating member 106 for rotating the camera 180 degrees, an omnidirectional rotating member 107 for rotating the camera head 360 degrees in all directions, and the camera head ( And a signal transmission wiring 108 connected to the rear portion of the 103.

In the conventional perspective camera having the above structure, since the wheels are fixed, when the wheel width of the camera is smaller than the diameter of the pipeline, the wheels are difficult to run because sludge remaining in the pipeline falls out. There is a problem that is used only in a very limited need to select a specification for the diameter width of each pipe diameter.

In addition, the external wiring for rotating the camera in the front and left and right directions and the signal transmission line for operating the camera are exposed to the outside, so that the wiring cannot be caught by the projection when traveling inside the pipeline. In addition, there is a possibility that a short circuit may occur when the wiring contacts the sewage, and there is a problem that may adversely affect the camera.

Therefore, the present invention has been devised to solve the above problems, and to enable the front and left and right rotation of the camera head, so that the signal line of the camera and the power line for driving are not exposed to the outside, and the width of the main wheel It is an object of the present invention to provide a sewage pipeline side view camera that allows the inside of the pipeline to be smoothly adjusted by varying the width of the pipeline.
