However, the prior art is configured by at least two hydraulic piping lines formed of a hydraulic cylinder structure on the runner blade side. The disadvantage is that it has a complicated structure.

In addition, the above-described hydraulic type of the prior art requires a lot of time and manpower for maintenance, such as oil drainage and refilling, while the structure is complicated, and when the oil is made of a large amount of water can cause a big problem in the aberration flow path flowing water There are disadvantages.

In particular, the above-described prior art has a problem that it is not possible to finely adjust the angle of the runner blade in accordance with the conditions of the water flow in the aberration passage.

Of course, as disclosed in Korean Patent No. 10-1302164, it is possible to increase the power generation efficiency by adjusting the angle of the runner blades with the driving force transmitted from the motor. However, the above-described prior art includes a motor and a generator for adjusting the angle of the runner blades. As the connecting shaft passes through the aberration flow passage, the structure prevents the flow of water, and the installation is limited according to the installation structure, and it can be used only in a limited aberration flow passage such as a bending section.

In addition, while the oilless bearing 201 is further provided on the outer surfaces of the feed shaft 210 and the piston 220 in the runner 40, the feed shaft 210 rotated in the runner 40 and The piston 220 may minimize rotational friction with the structure in the runner 40.

In the following, the operation of the blade opening and closing adjustment device of the bulb-shaped aberration according to the embodiment of the present invention described above will be described in more detail.

First, the driving unit 400 rotates the angle adjusting shaft 300.

As the angle adjusting shaft 300 rotates, the piston 220 of the angle adjusting unit 300 is moved to the rear side (the right direction in FIGS. 3 and 6).

At this time, the runner blade 100 is rotated as shown in FIG. 6 through the link part 330 connected to the piston 220 and the runner blade 100 is set up in the same direction as the water flowing in the aberration channel 10. The blade 100 is in an open state.

At this time, since the runner blade 100 is open in the bulb-shaped aberration, water flowing in the aberration flow path 10 flows to the rear of the aberration flow path 10 without being influenced by the runner blade 100.

Subsequently, when the driving unit 400 reversely rotates the angle adjusting shaft 300 by the operator's operation, the piston 220 of the angle adjusting unit 300 rotates as the angle adjusting shaft 300 reverses. This is moved to the front side (the left direction in Figs. 4 and 7).

At this time, the runner blade 100 is rotated as shown in FIG. 7 through the link part 330 connected to the piston 220 and is erected in an orthogonal direction of water flowing in the aberration flow path 10. The runner blade 100 is in a closed state.

At this time, since the runner blade 100 is closed in the bulb-shaped aberration, water flowing in the aberration passage 10 is blocked by the runner blade 100.

Thus, the runner blade 100 may achieve a predetermined angle in the runner 40 by adjusting the rotational driving amount of the shaft support member 230 so that the runner blade 100 has a predetermined angle.

As a result, the water flowing in the aberration passage 10 hits the runner blade 100, so that the runner 40 and the rotation shaft 30 rotate.

Subsequently, as the rotary shaft 30 rotates, rotational energy is supplied to the generator 50 and electrical energy is produced.

In this case, the angle of the runner blade 100 may be adjusted by operating the driving unit 400 according to the water flowing in the aberration passage 10.

As such, the blade opening and closing adjustment device of the bulb-type aberration according to the present invention is installed in the water flow path 10 through which water can flow to finely adjust the angle of the runner blade 100 without disturbing the flow of water, and thus the environment of water flow. Can maximize the power generation efficiency.

In addition, the blade opening and closing adjustment device of the bulb-shaped aberration according to the present invention can be made of a simple structure to reduce the manufacturing installation cost, the bulb case 20 inside the passage 60 is made easy to maintain.
