Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a wire that is inserted into a pipe such as an electric wire or a communication line and used to detect the condition inside the pipe.

[0002]

[Prior art]

 Conventionally, since this type of wire is made of a copper wire, it lacks in rigidity, which sometimes hinders the insertion of an electric wire or a communication wire into a pipe.

[0003]

[Problems to be solved by the device]

 That is, the above-mentioned conventional in-pipe insertion line has a problem that it is particularly difficult to insert it into a bent pipe, it cannot be inserted deep into the pipe, and it is difficult to detect the condition inside the pipe. Was there.

Therefore, the present invention solves the problem of the above-mentioned conventional insertion line in the pipe, and makes it easy to insert the pipe even to the back even if the pipe has a bend, and The purpose was to provide a line for insertion in a pipe that makes it easier to detect.

[0005]

[Means for Solving the Problems]

 Therefore, in the in-pipe insertion line of the present invention, a plurality of metal wires 1 including at least one steel wire 1a are separated from each other and integrally molded with a flexible synthetic resin material to form a wire main body 2 Is assumed to have been formed.

In the in-pipe insertion line of this invention, the metal wire 1 other than the steel wire 1a can be a copper wire 1b.

Further, in the in-pipe insertion line of the present invention, the metal wire 1 other than the steel wire 1a may be the steel wire 1a.

[Embodiment of device]

 Hereinafter, embodiments of the in-pipe insertion filament of the present invention will be described in detail with reference to the drawings.

In the embodiment shown in FIG. 1, the in-pipe insertion wire of the present invention has flexibility by separating two steel wires 1a, 1a from each other as a plurality of metal wires 1. It is assumed that the wire main body 2 is formed by integrally molding a synthetic resin material. Although not shown in the figure, the steel wire 1a may be a stranded wire formed by twisting a plurality of thin steel wires into one. The steel wire 1a is preferably a hard steel wire, a piano wire, a stainless steel wire or the like.

Therefore, in the insertion filament of this embodiment, the main body 2 as a whole has rigidity due to the two steel wires 1a, 1a, and if necessary, at the tip of the insertion filament, a lamp, a sensor, By connecting the two steel wires 1a and 1a to a transmitter and passing them through the pipes of electric wires and communication lines, and supplying electricity to the steel wires 1a and 1a, a lamp can be turned on in the pipes, a sensor, a transmitter, etc. It is possible to detect the condition inside the pipe by activating a vessel or the like.

In the embodiment shown in FIG. 2, the in-pipe insertion filament of the present invention is a plurality of metal wires 1, and two copper wires 1b and 1b are provided on both sides of one steel wire 1a. The wire main body 2 is formed by being separated from each other and integrally molded with a flexible synthetic resin material. As the copper wires 1b and 1b, as with the steel wire 1a, a twisted wire obtained by twisting a plurality of thin annealed copper wires into a single wire as shown in the figure may be used.

Therefore, in the insertion wire of this embodiment, the single wire 1a makes the wire main body 2 as a whole rigid, and if necessary, at the tip of the insertion wire, the lamp, the sensor, By connecting the two copper wires 1b, 1b to a transmitter, etc., and passing them through the pipes of electric wires, communication lines, etc., and supplying electricity to the copper wires 1b, 1b, lamps can be attached in the pipes, sensors, It is possible to detect the condition inside the pipe by operating a transmitter or the like.

In the embodiment shown in FIG. 3, the in-pipe insertion filament of the present invention is a plurality of metal wires 1 and two copper wires are provided between two steel wires 1a, 1a separated from each other. The wires 1b and 1b are separated from each other and integrally formed of a flexible synthetic resin material to form the wire main body 2. As the copper wires 1b and 1b, a twisted wire obtained by twisting a plurality of thin annealed copper wires into one as shown in the figure may be used.

Therefore, in the insertion filament of the present embodiment, the main body 2 as a whole has rigidity due to the two steel wires 1a and 1a, and if necessary, at the tip of the insertion filament, a lamp, a sensor, By connecting the two copper wires 1b and 1b to a transmitter and passing them through the pipes of electric wires and communication lines, and supplying electricity to the copper wires 1b and 1b, a lamp can be turned on in the pipes, a sensor, a transmitter, etc. It is possible to detect the condition inside the pipe by activating a vessel or the like.

[0015]

[Effect of device]

 Since the insertion line in the pipe of the present invention is configured as described above, even if the pipe has a bend, it can be easily inserted deep into the pipe to detect the state inside the pipe. It became easy to do.
