Instrument driving system using in-pipe flow power generation {MEASURING INSTRUMENT DRIVING SYSTEM USING PIPE FLOW POWER GENERATION}

The present invention relates to an instrument driving system using in-pipe flow power generation, and more particularly, to a measuring instrument driving system using in-pipe flow power generation that can improve power generation efficiency even when the flow amount of a fluid flowing in a pipe is small or the flow rate is slow. .

In general, in order to produce electricity, electricity was produced using nuclear power that mainly generates fossil fuels or radioactive materials, such as thermal power generation and nuclear power generation.

Such a power generation method inevitably produced harmful results such as soot and radioactive waste, which are the main culprits that pollute the environment in the process of generating electricity.

In addition, in the case of fossil fuels, since the reserves on earth are limited, if they are continuously mined and used, they are depleted on the earth and cannot be used indefinitely.

In addition, a huge amount of money is required to install the mining facilities necessary to mine fossil fuels, and there is a problem in that the environment is inevitably polluted even when fossil fuels are mined.

In order to solve this problem, in recent years, a power generation method that produces electricity using an infinite energy source generated in a natural state without polluting the environment, such as naturally occurring hydraulic power, wind power, tidal power, and solar heat, has been proposed.

Among them, in the case of the hydroelectric power generation method, electricity is generated by converting the kinetic energy of flowing water into the rotational power of the fluid device. In general, the focus has been on using the potential energy of the water stored in the dam.

In the case of such hydroelectric power generation, large-scale power generation facilities are required, which requires a large initial installation cost, and there are disadvantages in that power production efficiency is lowered if drought is frequent and precipitation is not constant.

In addition, in recent years, electricity is produced using the kinetic energy of various fluids flowing inside various piping systems such as tap water as well as fuel supply pipes or sewage drainage pipes, and by using this, electricity is generated without a separate power line connection to various measuring instruments attached to the pipe. A measuring device that can be driven by

However, in the instrument driving systems using in-pipe power generation according to the prior art, it is difficult to expect a sufficient power generation effect when the flow amount of water flowing through the pipe, such as a pipe, is small or the flow rate is slow, the internal configuration is complicated, and the installation work in the pipe is also difficult. there was.
