Description

Detailed Description of the Invention

[0001]

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

[0002]

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

Generally, the sewage mass is installed at an important portion of the conduit such as a gathering point or a bending point of the drainage pipe, and a lid attached to the opening prevents emission of odors and the lid must be removed. The system allows you to inspect the inside of the pipeline from the surface.

As for the pipeline of such a drainage system, when a new construction of a house is carried out, 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 sediments, 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 wastewater mass 22
Either to irradiate the light of the flashlight 25 into the same sewage mass 22 or to irradiate the light of the flashlight 25 to another adjacent sewage mass 23 with the mirror 24 inserted in 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 pipeline 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. Further, 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 particularly 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. A device main body including a flexible tube extending from the tip of the pole with a lamp at the tip, and a pipe line attached to the outside of the tip of the pole and having a variable protrusion length from the tip of the pole It is characterized by comprising an adjustment bar at an inner position, and forming an electric circuit for blinking a lamp through a power source built in the pole by operating an external switch in the apparatus main body.

In the inspection apparatus of the present invention, the external switch for blinking the lamp is preferably a blinking switch which also has a function of adjusting the light quantity of the lamp, and the light path can be adjusted by enabling the light quantity to be adjusted. The accuracy of inspection can be improved by irradiating the inside with appropriate light.

Further, since the tip part including the lamp is arranged in the pipeline of the drainage equipment, this inspection apparatus is entirely formed of a corrosion-resistant material that can withstand water and moisture, and particularly the lamp It is desirable that the main body of the device containing the blinking mechanism has a watertight structure in order to prevent a short circuit or the like.

[0011]

The inspection device of the present invention is used for inspecting the condition in the drainage pipe between the wastewater masses.

That is, this inspection device is inserted into one of the sewage masses to adjust the length of the pole, the irradiation direction of the lamp by bending the flexible tube, and the protruding length of the bar for adjusting the conduit position. By the adjustment, the switch at the base end is located at the position where it is easy to operate on the upper part of the sewage mass, and it is arranged so that it is in the predetermined direction on the central axis of the pipe to be inspected by the lamp. Inserts a mirror for inspection and arranges it so that the surface of the mirror faces the inspection device at an angle of 45 ° with respect to the central axis of the conduit.

In this state, the lamp of the inspection device is turned on, the light beam of the lamp is refracted at an angle of 90 ° by the mirror and reflected upward, and the state inside the pipe is observed from the upper part of the waste water mass in which the mirror is arranged. It is a thing.

By using such an inspection device, it is possible to observe the accumulation of water and the flow condition of water in the pipeline at a glance, and it is possible to easily inspect the pipeline for a short time.

According to this apparatus, the inside of a small-diameter pipe or a long pipe can be clearly imaged, and a single inspector can perform a quick and accurate inspection.
