Description

TECHNICAL FIELD [0001] The present invention relates to a pipe internal inspection device and a pipe internal inspection method using the pipe internal inspection device.

The present invention relates to an apparatus for irradiating an inside of a channel and a method for irradiating the inside of the channel with water at a lower speed than that of flowing water, And a method for inspecting an inside of a pipeline using the same.

At present, there are problems in water and sewage in Korea due to high proportion of aged phase and sewerage which are not replaced. That is, the water quality is contaminated during the transportation of the water by the sewage pipe due to the corrosion, the generation of the capstone, the generation of the foreign substance, the peeling of the cover, etc., and the cost is wasted due to the leakage, or foreign substances or bacteria are inhaled There is a possibility.

In order to investigate the internal condition of the pipe such as whether or not the scale and the sewage pipe buried in the underground are deposited, corrosion of the inside and the inside of the sewage pipe is discriminated by using the sewage pipe endoscopic equipment.

In particular, in the case of a water pipe, it is not possible to apply a wheel driven type as in the conventional sewage pipe irradiation equipment, so that a technology for partially photographing the inside using a small endoscope camera is being applied.

Such a conventional pipeline internal irradiation apparatus is a device for photographing a situation in a pipeline by pushing an endoscope camera into a cable by an understanding workforce in a state of endless water, and it is possible to insert about 10 cm to 15 cm each in the upstream side or the downstream side.

However, in this case, there is a limit of the photographable distance, and when the endoscopic camera advances by pushing the cable with the force, there is a problem that advancement of the endoscopic camera is difficult when scale or sediment is present in the channel. In the case of the water pipe, .

In another conventional pipeline internal irradiation apparatus, the condition of the tube and the valve is observed through the camera, the external monitor, and the controller in the air valve or perforation of the water pipe in the end water state.

However, even in this case, only the range where the camera is rotated can be photographed, so that only the portion where the apparatus is inserted can be investigated, and there is a problem that the state of the entire pipeline can not be diagnosed.

Since the conventional method of diagnosing the aging condition of the inner surface of the endoscope using the conventional endoscope equipment does not detect a long distance at a time, it is necessary to repeatedly detect the various points and thus it takes a lot of time and cost.

Fig. 2 is a perspective view showing the construction of the pipeline inner irradiation device 100, and Fig. 3 is a schematic view schematically showing the structure of the pipeline irradiation main body 110. As shown in Fig.

As shown in the drawing, the pipeline irradiating body 110 moves along the water flow W in the pipeline A and photographs the inside of the pipeline A. The pipe irradiation main body 110 includes a cell 111, a camera 113 disposed at one end of the cell 111, an illumination 115 illuminating the camera 113 at the time of photographing, A storage 113 for storing images photographed by the camera 113, a power supply 119 for supplying power to the camera 113 and the illumination 115, .

The cell 111 is a case having a hollow tube shape and accommodating therein a camera 113, an illumination 115, a storage unit 117, and a power supply unit 119. The cell 111 is preferably made of a lightweight material so that it can swim in the running water. The cells 111 may be formed in the shape of a circular tube as shown, or may be formed in the shape of a rectangular housing. It may also be formed in a spherical shape as the case may be.

The camera 113 photographs the inside of the duct when the cell 111 moves along the duct A. [ The camera 113 can be selected as a camera having a resolution suitable for the diameter of the channel A. [ A plurality of cameras 113 may be provided according to circumstances and power may be supplied to the camera 113 suitable for the diameter of the pipeline A to be selectively used.

The illumination unit 115 is disposed at one side of the camera 113 and adjusts the brightness so that the inside of the channel is clearly photographed by irradiating the inside of the channel A when the camera 113 is photographed.

The storage unit 117 stores images photographed by the camera 113. In the channel irradiating main body 110 according to the present invention, the storage part 117 is provided inside the cell 111, but may be provided inside a ground control part (not shown) as the case may be. In this case, the channel illumination main body 110 and the control unit (not shown) communicate with each other through a communication unit (not shown) and can receive the photographed image.

 Meanwhile, a plurality of coupling wires 112 coupled to the auxiliary cable 140 are provided on one side of the cell 111. The coupling wire 112 is coupled at one end to the cell 111 and at the other end to the auxiliary cable 140.

It is preferable that the bonding wire 112 is formed of a metal material so as not to be broken by the strong rotating force of the auxiliary cable 140.

The power supply 119 supplies power to the illumination 115 and the camera 113. The power supply unit 119 may be detachably coupled to the cell 111 in the form of a battery.

The traction flare 120 forms a resistive force against flow velocity of the flowing water so that the channel irradiating main body 110 is not moved rapidly along the flowing water inside the pipe A. [ And forms a traction force so that the channel irradiating main body 110 is allowed to flow in the flow direction of the flowing water.

The traction flare 120 according to the present invention is formed in the form of a parachute as shown in FIG. 1, and is formed in a direction perpendicular to the moving direction of the running water W to form a resistance force against the running water W, The pipe irradiation main body 110 is pulled in the flow direction of the water flow.

The pulling flare 120 is formed in the form of a cloth which can be spread vertically in the pipe A to widen the contact area with the flowing water to form a resistance force and a pulling force.

The outer periphery of the traction flare 120 is coupled to the channel irradiation body 110 by the detachable wire portion 130. To this end, a plurality of coupling rings 121 may be provided on the outer periphery of the traction flare 120.

The pulling flare 120 is vertically spread in the pipe A as shown in FIG. 2 by engagement with the detachable wire portion 130 to form a resistance force so that the channel light emitting body 110 floats in the pipe A do.

By providing the pulling flare 120, it is possible to prevent the duct irradiation main body 110 from being quickly swept away by the water W due to the moving speed of the water W and failing to photograph the inside of the duct properly, The main body 110 can smoothly move in the flowing direction of the running water.

5, when the channel irradiating main body 110 is to be recovered, it is separated from the attaching / detaching wire part 130 so as to be horizontally folded in the moving direction of the running water W, 110) can be easily recovered.

The detachable wire part 130 detachably couples the channel irradiation body 110 and the draw flare 120 with each other. The detachable wire portion 130 includes a fixed wire 131 fixed to one side of the outer periphery of the pulling flare 120 and a plurality of detachable wires 130 detachably connected to the pulling flare 120 at regular intervals along the outer circumference of the pulling flare 120 133).

The fixing wire 131 is fixed directly to the coupling ring 121 on one side of the traction flare 120 as shown enlarged in Fig. The fixing wire 131 is fixed to the traction flare 120 so that the traction flare 120 is not separated from the channel irradiation body 110 even if a plurality of detachment wires 133 are detached from the traction flare 120. [ The traction flare 120 can be recovered together with the channel irradiation body 110 without being flushed with the water when the channel irradiation body 110 is recovered to the ground by the fixing wire 131 and can be used repeatedly.

The detachable wire 133 maintains a state of being coupled to the traction flare 120 when the pipeline irradiation body 110 is inserted into the pipeline A from the ground. When the pipeline irradiation body 110 is recovered to the ground, And is separated from the irradiation main body 110.

A detachable clip (134) is provided at the end of the detachable wire (133). 4 (a) and 4 (b) are diagrams illustrating an operation process of the attaching / detaching clip 134. FIG.

The attaching / detaching clip 134 is formed in the form of an elastic spring which is curled as shown in Fig. 4 (a). The detachment clip 134 is configured such that when the traction flare 120 is moved at the speed of V1 in the water flow W, the magnitude of the force P0 acting in the opposite direction in which the traction flare 120 is moved is smaller than that of the detachment clip 134 Is kept smaller than the self-reference elastic force, the retained shape is retained in the state of being coupled to the coupling ring 121. [

That is, as shown in FIG. 1, when the auxiliary cable 140 is released and the channel irradiating main body 110 is moved along the running water W, the detachable wire 133 is removed to recover the channel irradiating main body 110 The applied force P0 becomes smaller than the reference magnitude. In this case, the attaching clip 134 retains the curled shape and is engaged with the engaging loop 121 so that the pulling flare 120 spreads perpendicularly to the channel A to form a resistance.

5, when the auxiliary cable 140 is pulled to the ground side in order to recover the pipeline irradiating main body 110 to the ground, the pipeline irradiating main body 110 moves in a direction opposite to the flowing direction of the flowing water The force P1 larger than the reference elastic force by which the attaching / detaching clip 134 is made to be engaged with the attaching / detaching wire 133 is applied as shown in Fig. 4 (b). When the force P1 greater than the reference elastic force is applied, the attaching / detaching clip 134 is elastically unfolded and separated from the engaging ring 121. [

When the plurality of attaching / detaching clips 134 are separated from the pulling flare 120, the pulling flare 120 is horizontally folded in the direction of movement of the pipe A, and resistance can not be formed.

Accordingly, the duct irradiation main body 110 is recovered to the ground by the pulling force of the auxiliary cable 140.

Here, the shape of the attaching / detaching clip 134 can be realized in various forms having a function of being released when a force larger than the reference elastic force is applied in a state in which it is curled by an elastic force.

The auxiliary cable 140 is provided for regulating the moving speed of the channel irradiating main body 110 and for recovering the channel irradiating main body 110.

The auxiliary cable 140 extends from the joint wire 112 of the channel irradiation body 110 to the ground. The auxiliary cable 140 can be manually operated by an operator or wound around the auxiliary cable winding member 160 as shown in Fig. 1 and automatically operated.

1 to 5, a description will be given of a process of irradiating the inside of the piping using the piping internal irradiation apparatus 100 according to the present invention having such a configuration.

The cylinder 150 is vertically installed on the upstream side of the channel A to be irradiated with the inside for the channel internal irradiation apparatus 100. The operator joins the cylinder 150 to the pipeline A and installs the auxiliary cable winding member 160 on one side of the cylinder 150. [

The channel irradiating main body 110 is prepared in such a manner that the fixing wire 131 and the detachable wire 133 are coupled to the pulling flare 120. An auxiliary cable 140 is coupled to the coupling wire 112 of the duct irradiation main body 110.

The worker injects the duct irradiation main body 110 into the duct A through the cylinder 150. [ Then, the auxiliary cable 140 is gradually released to allow the channel irradiating main body 110 to float along the running water W in the cylinder 150. The trailing flare 120 spreads in a direction perpendicular to the flowing direction of the channel A while the surface of the trailing flare 120 contacts the surface of the channel W. [ When the traction flare 120 is vertically unfolded, a resistive force and a traction force to resist the movement speed V of the flow water W are generated so that the channel irradiation body 110 moves slower than the movement speed of the flow of water W, The pipe irradiation main body 110 is moved in the flow direction of the flowing water by the pulling force. Here, the moving speed of the duct irradiation main body 110 is adjustable through the auxiliary cable 140.

The pipe irradiation body 110 is moved slower than the flow of water W by the resistance applied by the draw flare 120 so that the camera 113 captures the inside of the duct A. [ An image of the inside of the pipeline A taken by the camera 113 is stored in the storage unit 117. In addition, it is transmitted to a ground control unit (not shown) through a communication unit (not shown).

The operator confirms the image transmitted from the ground and, if there is a part of the pipeline to be additionally checked, winds the auxiliary cable 140 to slow down the moving speed of the channel irradiating main body 110 or retreats to the upstream side, .

The channel irradiation main body 110 photographs the interior of the channel A while moving along the flow of water W. When the image capturing of the pipeline A to be inspected is completed, the operator rotates the auxiliary cable winding member 160 to wind the auxiliary cable 140.

When the auxiliary cable 140 applies a pulling force in a direction opposite to the moving direction of the running water W, the detachable clip 134 is unfolded as shown in FIG. 4 (b) And is separated from the flare 120.

As a result, the traction flare 120 is folded as shown in FIG. The channel irradiation main body 110 and the traction flare 120 are moved together in the direction opposite to the flow of the water W, and are recovered to the ground.

As described above, according to the present invention, an apparatus for irradiating an inside of a channel can photograph an image of the inside of a channel while the channel irradiating body is swimming along the water inside the channel. Accordingly, the inside of the pipe can be photographed without a dead zone.

In addition, since the traction flare is coupled to the channel irradiating body to apply resistive force to the flowing water, the channel irradiating apparatus according to the present invention moves the channel irradiating body at a slower speed than the flowing water, There are advantages.

In addition, since the pipe irradiation main body is connected to the auxiliary cable, the operator can adjust the moving speed. Where a more detailed image is required, the pipe irradiation main body can be retracted and the image can be secured.

In addition, there is an advantage that an auxiliary cable can be wound and the pipe irradiation main body can be easily recovered.

It is to be understood that both the foregoing description and the preferred embodiments of the present invention are by way of example only and it is to be understood that those skilled in the art will appreciate that various modifications, It will be appreciated that embodiments are possible. Therefore, it is to be understood that the present invention is not limited to the above-described embodiments.
