Power generator for piping {Power generator for piping}

The present invention relates to a power generation device that is mounted on a pipe through which a fluid flows to generate electricity by the flow force of the fluid, and in more detail, a rotation shaft connected to the generator is mounted across a flow path of the piping unit, and a rotation shaft on the rotation shaft A guide to rotate is fastened, and a guide ring provided with a plurality of blades, which mainly receives a fluid flow force, is fastened to the guide.

In general, in order to produce electricity, electricity was mainly produced by using fossil fuels or nuclear power that generates radioactive substances harmful to the human body, such as thermal power generation and nuclear power generation.

This power generation method inevitably caused harmful results such as soot and radioactive waste, which inevitably pollute the environment in the process of generating electricity.

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

To solve this problem, in recent years, a power generation method that generates electricity using an infinite amount of energy sources generated in natural conditions has been proposed without polluting the environment such as naturally occurring hydropower, wind power, tidal power, and solar heat.

Among them, in the case of the hydroelectric power generation method, electricity is generated by converting the kinetic energy flowing of water into the rotational power of a fluid device, and 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-sized power generation facilities are required, which incurs enormous installation costs at the beginning, and there is a disadvantage in that power production efficiency is lowered if drought is frequent and precipitation is not constant.

Therefore, recently, research on the power generation method of generating electricity by using it without wasting the kinetic energy of the fluid flowing variously inside various piping systems such as tap water, fuel supply pipe or sewage drainage pipe has been actively conducted. There is a situation, and some small and medium-sized power generation devices are being disclosed.

The following is a typical prior art for a power generation device mounted on a pipe.

Republic of Korea Patent Publication No. 10-2011-0104628 relates to a hydraulic power generator for piping, a flange pipe that is flange-joined between straight pipes, and a flange pipe that is located inside the flange pipe in the longitudinal direction of the flange pipe, but the central axis is It is fixed to the inner diameter of the flange pipe by at least one shaft supporter, the first bevel gear is formed at one end, and is located outside the flange pipe and the screw turbine having a plurality of blades installed at regular intervals, the outer diameter of the flange pipe It includes a driven shaft penetrating through a boss installed on the shaft, and a second bevel gear installed at one end of the driven shaft and engaged with the first bevel gear, and a generator connected to the other end of the driven shaft to generate electric energy. A hydraulic power generator for piping was suggested.

In addition, the power generation device according to the prior art can be installed on various types of pipes that have been installed by flange connection between the pipes, so that it is easy to install at low cost without dismantling the existing facilities. Due to the large resistance of the Korean impeller (screw turbine), there is a problem that the fluidity of the fluid is slightly lowered, and continuous research and development is required to solve this problem.

Republic of Korea Patent Publication No. 10-2011-0104628 (2011.09.23.) Korean Patent Application Publication No. 10-2013-0074722 (2013.07.04.) Republic of Korea Patent Publication No. 10-1497658 (2015.02.24.) Republic of Korea Patent Publication No. 10-1555433 (2015.09.17.)

The present invention is a technology conceived to improve the problems associated with the prior art of the power generation device for piping, and the conventional power generation device has a simple structure in which an impeller connected to the generator is inserted into the flow path of the pipe through which the fluid flows, so the impeller for the fluid There was a problem that the flow of fluid was excessively inhibited due to the large resistance of

In particular, the structure of the impeller installed in the flow path of the pipe is complicated, and since the rotation shaft of the impeller and the rotation shaft of the generator are connected in a vertical crossing form by the worm gear, the power generation efficiency is low and the resistance of the fluid is large. The main purpose is to provide a solution to the problem of poor liquidity.

The present invention is to realize the desired object as described above,

The power generation device for piping according to the present invention presented as above has a configuration in which the rotation shaft crosses the flow path of the pipe and is mounted on the piping unit, so that the rotation shaft of the generator and the rotation shaft of the power generation device can be directly connected without separate components such as a worm gear. You can get a good effect;

In particular, the blade that rotates the rotating shaft by receiving the flow force of the fluid mainly receives a large flow force of the fluid flowing in one direction, but it is configured to rotate while receiving the minimum resistance of the fluid, thus inhibiting the fluidity of the fluid. It does not and can obtain an effect that can increase the power generation efficiency.
