Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention visually inspects the condition of water flow and the degree of stagnation of water in various drainage facilities such as drainage pipes laid in residential land and public drainage pipes connected to these drainage pipes. The present invention relates to a pipe line inspection device in a drainage facility.

[0002]

2. Description of the Related Art Household sewage mainly for drainage such as flush toilets, kitchens, bath tubs, etc. is led to the outside by drainage pipes buried in the soil, and passes through a wastewater mass and an attachment pipe to a public drainage pipe. Spill to.

Generally, the sewage mass is installed at an important part of the pipeline such as a gathering point or a bending point of the drainage pipe, and a lid attached to the opening prevents emission of an odor and removes the lid. The system allows the inside of the pipeline to be inspected from the ground surface.

As for the pipeline of such a drainage system, when a new construction of a house is performed, the newly laid pipeline is flushed with water to inspect the condition of the flow of water in the pipeline and the presence or absence of stagnant parts of water. Also,
As for the existing pipelines, the same inspections as above will be performed from time to time to check for water stagnation and the presence of deposits, and if any defect is found by this inspection, appropriate measures will be taken.

Specifically, such an inspection is carried out by flowing water into the pipe line 21 including the wastewater masses 22 and 23 as shown in FIG.
A mirror 24 for reflection from the upper part of the one sewage mass 22
Either the light is emitted from the flashlight 25 into the same sewage mass 22 or the light from the flashlight 25 is radiated onto another adjacent sewage mass 23 while the mirror 24 is inserted into the sewage mass 22. The light by the mirror 24
When observing the inside of the pipeline 21 from above the wastewater mass 22,
The degree of sewage flow depending on the degree of inclination of the pipe 21 and the presence or absence of stagnant water are determined.

[0006]

Of the above inspection methods,
The former method, which uses the mirror 24 and the flashlight 25 from the same sewage mass 22, has a drawback in that the light irradiated to the inside of the conduit 21 is weak and the visible range becomes extremely narrow. In addition, the latter method, in which the flashlight 25 is applied to the mirror 24 in different sewage masses, has a wider range that can be confirmed as compared with the former method. It is difficult to confirm the state, and there is a problem that it is difficult to confirm the state especially when the flowed water or dirty water is stagnant in the pipeline.

In view of such a present situation, the present invention provides a pipe line inspection device in a drainage facility, which allows light to be uniformly radiated over a wide range in the pipe line to clearly check the internal state. It is intended to be provided.

[0008]

In order to achieve the above object, a pipe line inspection device in a drainage system according to the present invention comprises a stretchable pole which is slidable by connecting a plurality of cylindrical bodies in an axial direction.
