Abstract

PROBLEM TO BE SOLVED: To reduce a burden on a pipeline with excellent operability even in the pipeline with branches. SOLUTION: Guides 27-1,..., 27-4 are successively inserted in a main pipe 5. A cable 17 is manually pushed in to move a body 11 in a passage 29 and a trunk pipe 1 in the state of the body 11 being enclosed in a head part 19. Upon reaching an inlet of a branch pipe 3, rubber of a watertight part 13 is expanded to fix the position of the body 11. The head part 19 goes outside of the body 11 from an opening 15 and advances in the branch pipe 3. At this time, the body 11 jets liquid toward the head part 19. The head part 19 rides on the flow of the jetted liquid and moves in the branch pipe 3 by rotating a screw 23 to inspect and clean.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving device in a pipe and a control method thereof.

[0002]

2. Description of the Related Art Foreign matter mixed in pipes, or adherence of dirt and sediment due to normal use, lowers the efficiency of gas and liquid transfer and supply through the pipes, thereby ensuring safety during supply. It is a hindrance factor. To prevent that,
Inspection and cleaning of the piping are required.

[0003] For this reason, there is an in-pipe inspection apparatus for inspecting the inside of a pipe, but the movement of the conventional in-pipe inspection apparatus has been performed by self-propelled operation such as wheel drive or the like, or by external pushing by human power or the like.

[0004]

However, in the case of self-propelled movement, the weight of the self-propelled vehicle must be increased in order to obtain sufficient force to pull the devices and cables, and the friction between the wheels and the pipes must be reduced. It is necessary to take large. In this case, the burden on the piping increases, and the operability deteriorates. In addition, it cannot be applied to a small-diameter pipe because the size of the apparatus becomes large.

[0005] In the movement by pushing by human power or the like, if the movement distance becomes long, the cable buckles and the force is not transmitted. Further, in the pipe through which the liquid flows, movement becomes difficult due to resistance received from the liquid. The present invention has been made in view of such a problem, and its purpose is to provide good operability even in a branched pipe.
It is an object of the present invention to provide an in-pipe moving device with less burden on a pipe and a control method thereof.

[0006]

According to a first aspect of the present invention, there is provided a main body, a first cable provided in the main body, and a propulsion mechanism which can be stored inside the main body. And a head portion directly connected to the main body by a second cable, wherein the head portion propels the inside of the pipe filled with liquid using the propulsion mechanism. Device. Further, a second invention is a control method for controlling the in-pipe moving device, comprising: a step of feeding a main body containing a head portion to a predetermined position by the first cable; A propulsion process in a branch pipe.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram showing a pipe moving device according to the present embodiment. Pipe moving device 10
Is composed of a main body 11, a cable 17, a head 19, and the like.

The main body 11 can house a head portion 19 therein, and is connected to a cable 17. Cable 17
Has an electric wire, a hose, and the like, and has strength (rigidity) to withstand pushing from outside. Watertight portions 13 are provided before and after the main body 11. The watertight portion 13 is made of rubber or the like, has an inflatable property, and expands when air or the like is supplied from the cable 17.

The head section 19 has a camera 21, a screw 23 and the like, and is connected to the main body 11 by a cable 25. The cable 25 has electric wires necessary for driving a camera, a screw, and the like, a water supply hose, and the like. The head unit 19 may have a function of jetting a jet stream and cleaning the inside of the branch pipe 3 in addition to capturing an image of the inside of the branch pipe 3 by the camera 21.

Each of the guides 27-1,..., 27-4 is a cylindrical body having a passage 29 provided therein. Passage 29
, 27-4 are provided inside the guides 27-1,..., 27-4, and the in-pipe moving device 10 passes through the passage 29.

Externally, a personal computer 41 and an air supply unit 4
3. The liquid supply unit 45 and the like are provided. The personal computer 41
It controls the in-pipe moving device 10 and displays an image captured by the camera 21.

The air supply section 43 is a compressor or the like, and supplies air to the watertight section 13 via the cable 17. The liquid supply unit 45 is a pump or the like, and supplies the liquid to the main body 11 via the cable 17. In FIG. 1, the main pipe 5 and the branch pipe 3 are connected to the main pipe 1, and a liquid such as water flows inside the main pipe 1 and the branch pipe 3.

Next, a procedure for inspecting or cleaning the inside of the branch pipe 3 using the in-pipe moving device 10 will be described.
First, the guides 27-4,..., 27-1 are sequentially inserted into the main pipe 5.

Next, the operator attaches the head section 19 to the main body 11.
When the main body 11 is inserted into the passage 29 in a state where it is stored in the main pipe 1, the main body 11 is moved inside the main pipe 1 and reaches the entrance of the branch pipe 3.
The rubber is expanded to fix the position of the main body 11. In this case, the operator pushes the cable 17 from outside the guide 27-1 to move the main body 11, and sends air from the air supply unit 43 to the air hose inside the cable 17 to expand the watertight portion 13.

Next, the head portion 19 protrudes from the opening portion 15 to the outside of the main body 11 and is propelled in the branch pipe 3. At this time, the head section 19 moves by rotating the screw 23, and at the same time, the liquid is supplied from the liquid supply section 45 to the main body 11, and the liquid is ejected from the opening 15 of the main body 11 toward the head section 19. At this time, the liquid supply unit 45 is
Is supplied to the branch pipe 3 side.

The in-pipe moving device 10 and the head 19 are
The specific gravity is adjusted to be substantially the same as that of the liquid, and the head 19 is propelled while floating in the branch pipe 3.

The head section 19 rides on the flow of the ejected liquid and moves by further rotating the screw 23 to perform inspection and cleaning. Furthermore, the head portion 19 can be propelled by pushing the cable 25. At this time, the main body 19
It is also possible to flush away the dirt inside the branch pipe 3 with the flow of the liquid ejected from the pipe.

As described above, according to the present embodiment, since the buoyancy of the in-pipe moving device 10 is adjusted, it is not necessary to consider an increase in the weight of the cable 25 or the like due to a long moving distance. Distance movement becomes possible. Further, unlike the heavy self-propelled type, the load on the piping can be small, and the size can be further reduced.

The liquid is ejected from the main body 11 toward the head portion 19, and since this propulsive force can be obtained more stably even at a long distance as compared with pushing from the outside, a long distance movement is possible. . Also, the driving force of the screw 23,
By applying an external pushing force, a larger moving propulsion force can be secured.

[0020]

As described in detail above, according to the present invention, the operability is good even in a branched pipe.
It is possible to provide an in-pipe moving apparatus and a control method thereof that place less burden on the pipe.
