Description

Tubular type watertightness permanent magnet synchronous power generation system with vortex prevention guide vane}

The present invention relates to a vortex-preventing guide vane and a flow-through type waterproof permanent magnet synchronous power generation system having the same, and in particular, at least two are provided in a connecting channel that converts the flow of water vertically, one end being bent toward the inlet, and the inflow of water It relates to a vortex-preventing guide vane having a shorter length and a lower height toward the direction side, and a flow-through type waterproof permanent magnet synchronous power generation system having the same.

After the Kyoto Protocol came into force, the discovery of new and renewable energy sources has become a concern of the state and local governments. Among them, small-scale power generation has a very high potential for use, as well as alleviating the national overload of the national power supply chain, and the possibility of generating zero-carbon conditions. Interest is gradually increasing due to the effect of replacing the power generation resources that are used.

In general, the small hydro power generation uses a propeller aberration that generates electric energy by directly connecting the rotational force of a propeller to a propeller drive shaft and a power generation system drive shaft. This is a structure that generates electric energy by artificially installing a dam at the upper part and converting potential energy into kinetic energy. In the case of a sewage terminal treatment plant, the drainage channel through which the discharged water flows is formed into a low drop. Since it is an environment that cannot induce a drop by installing, there is a problem that a hydropower device cannot be installed.

Accordingly, a once-through power generation system capable of performing small hydropower generation with many advantages even in a low free fall structure is in the spotlight.

Such a once-through power generation system is installed in a sewage pipe, and the discharged water flowing from the sewage terminal treatment plant to the river flows into the sewage pipe to perform power generation.At this time, the discharged water flowing into the sewage pipe is a connection that introduces water in a vertical direction with respect to the length of the sewage pipe. It flows into the waterway and flows into the sewer pipe.

As shown in Fig. 1, which is a drawing, the incoming water hits the surface facing the inlet of the connection channel 1, that is, the wall formed in the direction of the inflow of water, and then flows in the opposite direction to generate a eddy current phenomenon.

In addition, when passing through the sewage pipe 2 and discharged through the drainage channel 3, it is also discharged in a vertical direction.Also, as shown in FIG. 1, after the discharged water hits the wall in front, it proceeds in the opposite direction. It flows and causes a eddy current phenomenon.

Accordingly, a phenomenon in which the flow of water is stagnated occurs inside the connection channel and the discharge channel, and thus, the rotational force of the power generation device that performs power generation in the sewage pipe decreases, so that efficient power generation cannot be performed.

In addition, excessive generation of air bubbles is generated due to a pressure drop due to the occurrence of eddy currents, and noise and vibration are generated when passing through the propeller of the power generation device, and in severe cases, there is a problem of damaging the propeller of the power generation device.
