Description

[0001] FLOATING-TYPE APPARATUS FOR MONITORING COLLECTING PIPE [0002]

The present invention relates to an apparatus for inspecting a floating additional pipe line, and more particularly, to a floating type pipe line inspection apparatus for photographing an image inside a pipe line for inspecting a pipe line.

Generally, the subway pipeline refers to a pipeline for collecting a certain amount of sewage from a combined sewerage system in the case of clear stream or rain, and transporting it to a sewage treatment plant. Such an overhead pipe may cause corrosion in the interior due to long-term use, or sludge may be deposited on the inside of the pipe, thereby interfering with the flow of sewage.

Therefore, the inspection work for confirming the abnormality of the auxiliary pipeline can be visually confirmed in the pipeline if the operator has a large-diameter pipeline into which the operator can enter. However, Since most of the pipes are small in diameter so that they can not be inserted by the operator, it is impossible to directly check by the operator. Therefore, the photographing equipment, which can be driven by itself, is inserted into the pipe to photograph the internal state of the pipe .

Normally, a certain amount of water flows in the auxiliary pipe line. When inspecting the auxiliary pipe, both ends of the inspection zone to be inspected are blocked to block the water (water blocking), and water in the inspection zone flows to another section ) The next shooting equipment (CCTV) is injected into the pipeline, which is disadvantageous in that the construction cost is too high and the operation speed is slow.

Recently, as shown in Korean Patent Registration No. 1146195, " Power Transfer Floating Substitute Duct Inspection Apparatus "and Korean Patent Registration No. 1111150" Suspension Suppression Substitute Duct Inspection Apparatus " So that the photographing equipment can be floated so that the CCTV equipment can be immediately introduced into the secondary pipe without having to block water or turn the water in the inspection zone and photograph the interior of the secondary pipe.

Particularly, in the float-type pipe inspection apparatus, a buoyancy tank is provided on both sides of the float to prevent the photographing equipment from rotating or shaking in one direction in accordance with the flow of water flowing through the access pipe, So that the floating body can be prevented from turning in the lateral direction.

However, when the buoyancy tank collides with the inner circumferential surface of the auxiliary pipe, the inspection apparatus of the floating exchange pipe inspection system transmits the impact to the imaging equipment mounted on the floating body as it is, So that the floating of the floating fluid is not smooth.

In addition, the floating auxiliary pipe is provided only at the left and right sides of the float tank, so that the floating and tilting of the floating tank in the vertical direction can not be prevented so that the shaking of the photographed image still occurs.

Accordingly, there is an urgent need to present a new technology capable of solving the problems of the prior art.
