Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows an observation apparatus according to an embodiment of the present invention, and FIG. 2 shows an exploded view of the observation apparatus of FIG.

The observation device comprises a housing 10 projecting to the outside of the pipe 1 and communicating with the pipeline 1 in an airtight manner and communicating with the pipe 1 at one end, a support unit 50, 60, 70 at one end and a coupling bracket The flexible tube 30 is composed of a flexible body 31 and a cable 30 which is inserted into the tube 30 and extends to the outside of the tube 30 100).

Hereinafter, each component will be described in detail.

<Housing (10)>

The housing 10 is hermetically coupled to the pipe 1 by welding or the like so as to protrude out of the pipe 1 in a cylindrical shape so that the flange is formed at the other end so as to be easily and simply coupled with the flexible tube 30 do.

Here, gas containing toxic gas or powder may flow or liquid may flow in the piping 1, and therefore, the housing 10 and the piping 1 must be hermetically bonded.

The length of the housing 10 protruding outside the pipe 1 is not limited. However, it is only required that the flexible tube 30 can be accommodated when the flexible tube 30 is compressed and has the shortest length.

Referring to Fig. 1, a gas supply port 12 is formed in the housing 10 adjacent to the pipe 10 and a joint portion, for example, an inert gas is supplied.

The position where the gas supply port 12 is formed is substantially coincident with the position corresponding to the end of the sealing cap 70 when the flexible tube 30 is compressed and has the shortest length, Foreign materials such as powder remaining in the vicinity of the end of the sealing cap 70 can be removed by the inert gas injected from the sealing cap 70, thereby securing the field of view of the image sensing unit 40.

<Flexible tube 30>

In this embodiment, the flexible tube 30 is constituted by a stretchable body 31, a fixing portion 34 formed at one end of the body 31, and a coupling bracket 32 coupled to the other end of the body 31 do.

Since each part constituting the flexible tube 30 is exposed to the inside of the pipe 1 and the material remaining in the pipe 1 is chemically and electrically sensitive, the respective parts constituting the flexible tube 30, The support units 50, 60, 70 may be constructed of chemically and electrically stable materials.

Therefore, it is needless to say that the body 31 capable of expanding and contracting most of the flexible tube 30 is occupied by the expandable and contractible body, and the expandable and contractible body may occupy a part of the flexible tube 30 as described later.

As the body 31, a corrugated tube or a bellows may be used, and any shape capable of compressing and expanding in the longitudinal direction may be used.

A pipe-shaped fixing portion 34 is formed at one end of the body 31 to facilitate coupling with the sealing cap 70 as described later. A flexible tube 30 is mounted on the other end of the body 31, The engaging bracket 32 for engaging with the engaging bracket 10 is formed.

The coupling bracket 32 is formed in a flange shape and can be easily airtightly coupled with a flange formed at the other end of the housing 10. The coupling bracket 32 is formed in the center of the coupling bracket 32, A rib 32b is protruded inward along the edge of the through hole 32a and is connected to the body 31. [

Therefore, since the body 31 is supported by the ribs 32b, the body 31 can be freely and smoothly expanded and contracted within the housing 10.

A cable 100 is inserted into the flexible tube 30. An imaging unit 40 such as a CCD camera is installed at the end of the cable 100 to photograph the interior of the pipeline 1, (Not shown), and the image processing apparatus can display the transmitted image on the display or store the image on a remote or local storage.

The cable 100 has a configuration in which a portion of 40 mm to 60 mm is bent from the end where the image pickup unit 40 is mounted by an operation from the outside such as an endoscope cable so that the image pickup unit 40 is bent in forward, backward, Can be controlled.

The cable guide 20 can be fitted into the through hole 32a of the coupling bracket 32. A guide hole 22 is formed at the center of the cable guide 20 so that the cable 100 slidably passes. To this end, the cable guide 20 may be made of a Teflon material having excellent chemical resistance and low friction coefficient and having a smooth surface.

<Support Unit>

The support unit includes a holder 50 having openings 52 and 54 having different diameters passing through each other, a transparent lens 60 fitted into the large-diameter inlet 54 of the holder 50, And a tubular sealing cap 70 having a bottom on which the fixing portion 34 of the tube 30 is hermetically coupled.

The holder 50 supports the imaging unit 40 and the lens 60 and allows an accurate image to be input to the imaging unit 40 through the lens 60. The holder 50 is formed to penetrate in the longitudinal direction, An inlet 52 is formed and an inlet 54 having a large diameter is formed at the other end.

The small diameter inlet 52 is fixed to the fixed portion 34 of the tube 30 by inserting the imaging unit 40 into the smaller diameter inlet 52 and fixing the large diameter inlet 54, The lens 60 is fitted and fixed.

Rubber rings 62 and 64 are provided on the upper and lower surfaces of the lens 60 to block leakage through the lens 60, respectively.

In this state, the fixing portion 34 of the tube 30 is fitted and fixed to the sealing cap 70, and a sealing rubber 74 is interposed therebetween and tightly coupled.

According to this structure, the image pickup unit 40 can accurately and detailly photograph the state of the inside of the pipe 1 in a state where it is completely isolated from the inside of the pipe 1 by the support units 50, 60,

1, when the cable 100 is pushed in by an external operation, the body 31 of the tube 30 is extended, and the sealing cap 70 enters the inside of the pipe 1 as indicated by a dotted line, The cable 100 is externally operated to bend the end portion so that an image representing the state inside the pipe 1 can be taken at a desired position.

As described above, the end portion of the cable 100 is bent at an angle of, for example, a maximum of 120 degrees so that the imaging unit 40 can take an omnidirectional direction. As a result, the image pickup unit 40 is bent in all directions together with the cable 100, so that the inside of the pipe 1 is photographed.

As a result, it is possible to constantly observe the environmental changes such as the state of the pollutants inside the pipe and the damage of the inner wall of the pipe, thereby preventing occurrence of a dangerous situation and preventing property damage in advance.

According to this embodiment, the flexible tube 130 is inserted deeper into the pipe 1.

Referring to FIG. 3, the housing 110 is protruded to the outside of the pipe 1 and is inclined at a predetermined angle so that the flexible tube 130 is inserted obliquely, so that it can be inserted into the pipe 1 more deeply.

The flexible tube 130 includes a pipe body 131 having a coupling bracket 132 formed at one end thereof and a stretchable and contractible portion 133 formed adjacent to the fixed portion 134 at the other end.

The pipe body 131 maintains a bent state at an angle, and its tip end extends parallel to the housing 110 and the rear end extends parallel to the pipe 1.

According to this embodiment, the cable 100 is bent in the forward direction by the extensible portion 133 by the external operation, and as a result, the image pickup unit 40 is also bent in all directions to photograph the inside of the pipe 1 .

Referring to FIG. 3, a gas supply hole 136 extending radially from the edge of the coupling bracket 132 is formed, and inert gas is supplied into the tube 130.

A discharge hole 134a is formed in the fixed portion 134 of the tube 130 and an injection hole 171 is further formed in the bottom of the sealing cap 170 as enlarged inside the circle.

According to this structure, the inert gas supplied through the gas supply hole 136 is injected through the discharge hole 134a and the injection hole 171, so that the inert gas, which is adjacent to the observation hole 172 of the sealing cap 170, Can be removed.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or essential characteristics thereof.
