Description

[Technical field]

[0001] The present invention relates to a hydroelectric power generation system, and more particularly to a hydroelectric power generation system having a debris remover for removing debris from flowing water in a natural river. [Background technology]

[0002] There are many hydroelectric power generation devices that utilize the water flow energy of natural rivers in patent documents and the like. However, the present inventor has already proposed a hydroelectric power generation device, as shown in Patent Document 1, that is not affected by the water volume of the river and can constantly provide sufficient rotational force to the water turbine, thereby generating stable electricity even with a small water volume.

[0003] However, the hydroelectric power generation device shown in Patent Document 1 is not provided with a debris remover to remove debris from the flowing water falling into the water turbine, and it has been found that there is a problem in that debris mixed in the flowing water falls into the water turbine without being removed, reducing the operating rate of the water turbine.

[0015] Hereinafter, the present invention will be described based on an embodiment with reference to the accompanying drawings, but the present invention is not limited to only such an embodiment.

[0016] EMBODIMENT 1 FIG. 1 is a schematic diagram showing a hydroelectric power generation system S according to a first embodiment of the present invention. As shown in Figure 1, the hydroelectric power generation system S comprises as its main components a water turbine 10, a generator 20 connected to the rotating shaft 11 of the water turbine 10 to generate electricity, a storage tank 30 whose discharge outlet is facing the water turbine 10, a building (containment body) 40 that houses the water turbine 10, the generator 20 and the storage tank 30, a waterway 50 arranged on the roof 41 of the building 40, a dust collector 60 arranged on the downstream side of the waterway 50, and a dust discharge member 70 arranged below the downstream end of the dust collector 60.

[0017] Since the water turbine 10 and the generator 20 are of known structure, the following description will mainly focus on the characteristic parts of this embodiment.

[0018] In the illustrated example, the water channel 50 has a horizontal main section 51 located on the upper surface of the horizontal section 41a of the roof 41, and a downwardly sloping water drop section 52 located above the water wheel 10. Specifically, the water channel 50 configured in this way is formed by a water channel forming member P made by forming a steel plate into a groove shape. Although not shown, a receiving member of a predetermined thickness is disposed between the water channel forming member P and the horizontal section 41a of the roof 41, and a gap is provided between the horizontal section 41a of the roof 41 and the bottom surface of the water channel forming member P for the purpose of maintenance, etc.

[0019] As shown in FIG. 2, the water fall section 52 is formed with a water fall opening 52a so that the water fall can be supplied to the storage tank 30 disposed below, and a dust remover 60 is disposed in the water fall opening 52a to remove dust that has become mixed in the flowing water.

[0020] In the illustrated example, the inclination of the water fall portion 52 is shown as a gentle inclination for convenience of drawing, but the inclination of the water fall portion 52 is, for example, 10 degrees to 45 degrees.

[0021] The width of the water drop opening 52a in the flow direction is adjusted so that a sufficient amount of water can be supplied to the storage tank 30 disposed below. For example, the width is set to about 1 m.

[0022] As shown in Fig. 3, the storage tank 30 is in an inverted trapezoid shape, with a water inlet 31 at the upper end and a discharge outlet 32 ​​at the lower end. The water inlet 31 is positioned so as to face the water drop opening 52a, and the discharge outlet 32 ​​is positioned so as to face the water turbine 10. The inside dimensions of the water inlet 31 are made larger than the opening dimensions of the water drop opening 52a, so that water can be received without leakage.

[0023] As shown in Fig. 2, the dust remover 60 is configured by arranging a required number of rod-shaped dust removal members 61 at specified intervals in the width direction of the waterway 50. Note that in Fig. 2, the gaps between the dust removal members 61, 61 are exaggerated to make it easier to understand. This also applies to the following embodiments.

[0024] The dust removal member 61 is, for example, a round or square bar. However, a round bar is preferable because dust removed from the running water by the dust removal member 61 is easily detached from the dust removal member 61 by the water current that does not fall, and is then easily discharged from the dust discharge member 70. If a round bar is used, the diameter is, for example, 0.5 cm to 16 cm. The spacing between the dust removal members 61 is adjusted so that the gap between the dust removal members 61, 61 is 2 cm to 4 cm.

[0025] The waste discharge member 70 is, for example, a rack-shaped member whose both ends are joined to the downstream support pillar 42 of the building 40, the downstream end of the waste discharge member 61 is placed on the upper surface of the convex portion, and the concave portion forms the waste discharge portion 71.

[0026] The building 40 has a roof 41 which has a horizontal section 41a on which the main section 51 of the waterway 50 is placed, and an inclined section 41b on which the waterfall section 52 of the waterway 50 is placed, and its height and width are adjusted so that the water turbine 10, generator 20 and storage tank 30 can be accommodated.

[0027] The inclination angle of the inclined portion 41 b corresponds to the inclination angle of the water falling portion 52 .

[0028] A roof side opening 41c is provided at a location of the inclined portion 41b corresponding to the water drop opening 52a.

[0029] Thus, the excess water from the water fall section 52 (water that does not fall into the storage tank 30) falls outside the downstream outer wall 43 of the building 40. At that time, the garbage caught in the garbage collecting member 61 is discharged downstream by the water flow of this excess water.

[0030] As described above in detail, the hydroelectric power generation system S of this embodiment is designed to remove debris from the water flow supplied to the water turbine 10, thereby improving the operating rate of the water turbine 10 and generating power efficiently.

[0031] EMBODIMENT 2 FIG. 4 is a schematic diagram showing the main parts of the second embodiment.

[0032] The second embodiment is a modification of the first embodiment, in which a waste discharge member 70 is placed on the upper end of the downstream wall surface 43 of the building 40.

[0033] The remaining configuration of the second embodiment is the same as that of the first embodiment.

[0034] In this embodiment, since the waste discharge member 70 is placed on the upper end of the downstream side wall surface 43 of the building 40, the size of the waste discharge member 70 can be reduced compared to the first embodiment.

[0035] EMBODIMENT 3 FIG. 5 is a schematic diagram showing the main parts of the third embodiment.

[0036] The third embodiment is a modification of the second embodiment, in which the waste discharge member 70 is placed on a reinforcing beam 44 disposed between the downstream supports 42, 42 of the building 40.

[0037] The remaining configuration of the third embodiment is the same as that of the first embodiment.

[0038] In this embodiment, the waste discharge member 70 is placed on a reinforcing beam 44 arranged between the downstream supports 42, 42 of the building 40, so that the bearing strength of the downstream wall surface 43 of the building 40 can be reduced compared to embodiment 2, thereby reducing the cost of the wall surface.

[0039] Although the present invention has been described above based on the embodiment, the present invention is not limited to only such an embodiment and various modifications are possible.

[0040] In this embodiment, the water turbine 10, the generator 20, etc. are housed in a building 40, but for example, the water turbine 10, the generator 20, etc. may be made compact and stored in a box to form a portable hydroelectric power generation system.

[0041] Also, a bypass may be provided so that if an abnormal amount of water is predicted, the water flow can be directed through the bypass to avoid damage to power generation equipment such as the water turbine 10. [Industrial Applicability]

[0042] The present invention can be applied to a hydroelectric power generation system that utilizes natural rivers. [Explanation of symbols]
