Referring to FIGS. 1 and 2, the pipe foreign matter removing apparatus according to the present embodiment may include a generator 200, a vibration generator 300, and a controller 400.

The piping 100 may be used for various purposes in the entire industry, and may be formed into an empty pipe shape and used as a fluid path such as a liquid or a gas.

For example, the piping 100 may be installed on the seabed so that hydrocarbons and the like produced from an offshore plant can be transported overland. At this time, foreign matter such as wax or hydrate may be generated due to a decrease in the temperature inside the pipe 100 or other factors, and the phenomenon of being deposited on the inner surface of the pipe 100 may occur.

The vibration generator 300 may be installed on the piping to remove the foreign matter F generated inside the piping 100 to generate vibration in the piping. At this time, the generator 200 can convert kinetic energy generated from the outside of the pipe 100 into electric energy, and can supply the electric energy to the vibration generator 300.

Specifically, the generator 200 may include a body portion 210, a rotor blade 220, and a capacitor 230.

As shown in FIGS. 1 and 2, kinetic energy is generated on the outside of the pipe 100 due to a current or an air flow. As the body part 210 is rotatably coupled to the pipe, the body part 210 is rotated according to the generation direction in which the kinetic energy is generated, so that a greater amount of kinetic energy can be collected and converted into electric energy.

Also, the body portion 210 may be formed so as to have a reduced cross-sectional area along one direction to reduce resistance to currents or air currents.

In addition, the body 210 may include a stator (not shown) and a rotor (not shown).

The rotor blade 220 includes a plurality of blade members, and may be rotatably coupled to the main body 210 on an axis. Specifically, the rotor blades 220 are rotatably coupled to the rotors of the body 210, so that kinetic energy generated due to currents or airflows outside the piping 100 can be converted into electrical energy.

Some of the generated electric energy can be supplied to the vibration generator 300 and the control unit 400, and the remaining electric energy can be stored in the capacitor 230.

The capacitor 230 may be electrically connected to the body 210 to store electrical energy and may be electrically connected to the vibration generator 300 to supply electrical energy to the vibration generator 300.

Accordingly, when the vibration generator 300 and the controller 400 can not receive the electric energy from the body 210, the vibration generator 300 and the controller 400 receive the electric energy stored in the capacitor 230 Can be operated.

As described above, the apparatus for removing foreign substances in the pipe according to the present embodiment can supply electric energy to itself by using the current or air current generated outside the pipe 100, without needing to supply the electric energy separately from the outside.

In addition, the vibration generator 300 generates high-frequency vibration inside the pipe 100, so that generation of the foreign matter F inside the pipe 100 can be suppressed.

The temperature of the inside of the pipe 100 may be decreased due to the generation of the foreign matter F inside the pipe 100. The temperature of the pipe 100 may increase due to the kinetic energy of the pipe 100 through the operation of the vibration generator 300, The generation of the foreign matter F can be prevented by raising the temperature of the pipe 100.
