Abstract
Description
[Technical Field]
[0001] The present invention relates to a block. [Background technology]
[0002] Conventionally, concrete blocks, also known as wave-dissipating blocks, covering blocks, and base-protecting blocks, have been installed in ports, harbors, coasts, rivers, etc. In recent years, technologies have been proposed for wave power generation that utilizes wave force acting on concrete blocks, or for hydrodynamic power generation that utilizes hydrodynamic force (for example, Patent Document 1).
[0003] Patent document 1 describes a wave-dissipating block for wave power generation that is used in wave power generation using a method of converting wave energy into air energy, and that has a body portion and an air chamber that penetrates the front and back of the body portion. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-197949 Summary of the Invention [Problem to be solved by the invention]
[0005] The wave-dissipating blocks for wave power generation described in Patent Document 1 replace the gaps formed by multiple wave-dissipating blocks with air chambers and convert the air fluctuations within these air chambers into energy. In such wave-dissipating blocks for wave power generation, the gaps between multiple wave-dissipating blocks, which are important for achieving a wave-dissipating effect, are replaced with air chambers, which may impair the original function of the wave-dissipating blocks. Furthermore, when attempting to replace multiple wave-dissipating blocks already installed on-site with such wave-dissipating blocks for wave power generation, it may be necessary to change the structural specifications of the entire wave-dissipating structure composed of multiple wave-dissipating blocks.
[0006] The present invention has been made in consideration of the problems inherent in the prior art. An object of the present invention is to provide blocks that can perform wave power generation using wave force acting on the concrete block or hydrodynamic power generation using hydrodynamic force while maintaining their original functions as wave-dissipating blocks, covering blocks, root-protecting blocks, etc. Another object of the present invention is to provide blocks that can additionally perform wave power generation or hydrodynamic power generation without changing the overall structural specifications of a wave-dissipating structure, etc., that is composed of multiple blocks already installed on-site. [Means for solving the problem]
[0007] A block according to an embodiment of the present invention comprises a block body having a through-hole portion and placed in a coastal area, a sea area, a river area, or an outfall facility, and a turbine generator placed inside the through-hole portion and generating electricity using fluid flowing into the through-hole portion. [Effects of the Invention]
[0008] According to the present invention, it is possible to provide blocks that can perform wave power generation using wave force acting on the concrete block or hydrodynamic power generation using hydrodynamic force while maintaining their original functions as wave-dissipating blocks, covering blocks, root-fixing blocks, etc. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0010] The blocks according to this embodiment will be described in detail below with reference to the drawings. Note that the dimensional proportions in the drawings are exaggerated for the sake of explanation and may differ from the actual proportions.
[0011] [First embodiment] First, a block 1 according to the first embodiment will be described.
[0012] Fig. 1 is a perspective view of a block 1 according to the first embodiment. Fig. 2 is a plan view of the block 1 according to the first embodiment. Fig. 3 is a front view of the block 1 according to the first embodiment.
[0013] As shown in FIGS. 1 to 3, the block 1 includes a block body 10 and a turbine generator 2.
[0014] The block body 10 has a through-hole portion 11a and is placed in a coastal area, a sea area, a river area, or a discharge facility (a facility for discharging water from a dam or weir). The block body 10 is a flat block made of concrete. The through-hole portion 11a is formed by passing through the top surface (upper surface 10a) and the bottom surface (lower surface 10b) of the flat block (block body 10), and the turbine generator 2 is placed inside the through-hole portion 11a.
[0015] In the first embodiment, the flat block (block body 10) has a central portion 12 and four trunk portions 13 that radially protrude horizontally from the central portion 12, and is formed in an X-shape in a plan view. The central portion 12 is formed with a circular through-hole 11a that penetrates from the upper surface 10a to the lower surface 10b to release uplift pressure. Each trunk portion 13 is formed with an oval through-hole 11b that penetrates from the upper surface 10a to the lower surface 10b to release uplift pressure. In the first embodiment, a turbine generator 2 is disposed inside the through-hole 11a formed in the central portion 12 of the flat block (block body 10).
[0016] Furthermore, on the underside 10b of the flat block (block body 10), leg portions 14 are formed at the tip portions of the trunk portions 13, protruding downward from the underside 10b.
[0017] The turbine generator 2 is disposed inside a through-hole 11a formed in a flat block (block body 10), and generates electricity using a fluid W (see FIG. 3) that flows into the through-hole 11a. The turbine generator 2 is configured to include, for example, a circular frame-shaped housing 3, a turbine rotor 4 rotatably supported by the housing 3, and a stator (not shown) built into the housing 3. Wave force or fluid force acting on the block 1 is transmitted to the turbine generator 2, causing the turbine rotor 4 to rotate, thereby generating electricity.
[0018] FIG. 4 is an explanatory diagram showing a state in which a plurality of blocks 1 according to the first embodiment are arranged and these blocks 1 are connected to a facility 6 via a power transmission line 5. As shown in FIG.
[0019] As shown in Fig. 4, a plurality of blocks 1 are appropriately arranged, and a transmission line 5 is connected to the turbine generator 2 of each block 1. Furthermore, the terminal of this transmission line 5 is connected to a facility 6 such as a substation.
[0020] The block 1 according to the first embodiment is used, for example, as an armor block or a base securing block arranged at the base of a breakwater.
[0021] The effects of the first embodiment will be described below.
[0022] (1) The block 1 according to the first embodiment includes a block body 10 having a through-hole portion 11a and arranged in a coastal area, a sea area, a river area, or a discharge facility, and a turbine generator 2 arranged inside the through-hole portion 11a and generating electricity using a fluid W flowing into the through-hole portion 11a.
[0023] In the first embodiment, a through-hole 11a is formed in the flat block (block body 10), and the turbine generator 2 is disposed inside this through-hole 11a, so that the external shape of the block 1 is the same as that of a general flat block. Therefore, the function of the block 1 as a covering block or a base fixing block is not impaired, and there is no need to provide additional space for disposing the block 1.
[0024] As described above, according to the first embodiment, it is possible to provide a block 1 that can maintain its original function as a covering block or a root-fixing block and perform wave power generation using wave force acting on the concrete block or hydrodynamic power generation using hydrodynamic force.
[0025] (2) A power transmission line 5 is connected to the turbine generator 2 .
[0026] By connecting the terminal of this transmission line 5 to a facility 6 (see Figure 4) such as a substation, a power generation facility can be constructed that can perform wave power generation using wave power or hydrodynamic power generation using hydrodynamic power. Such a power generation facility can keep the initial cost and maintenance cost low compared to large-scale power generation facilities.
[0027] (3) The block body 10 is a flat concrete block. A through-hole 11a is formed through an upper surface 10a and a lower surface 10b of the flat block (block body 10), and the turbine generator 2 is disposed inside the through-hole 11a.
[0028] The block 1 configured in this way can be used, for example, as an armoring block or a base protection block placed at the base of a breakwater. Because the turbine generator 2 is placed inside the through-hole 11a of this block 1, the external shape of the block 1 is the same as that of a general armoring block or a base protection block. Therefore, the function of the block 1 as an armoring block or a base protection block is not impaired.
[0029] [Second embodiment] Next, a block 1A according to the second embodiment will be described. Note that components that are substantially the same as those in the block 1 according to the first embodiment are given the same reference numerals, and detailed descriptions thereof will be omitted.
[0030] Fig. 5 is a perspective view showing an example of a block 1A according to the second embodiment, and Fig. 6 is a front view of the block 1A according to the second embodiment.
[0031] As shown in FIGS. 5 and 6, the block 1A includes a block body 20 and a turbine generator 2.
[0032] The block body 20 has a through-hole portion 21 and is placed in a coastal area, a sea area, a river area, or a discharge facility. The block body 20 is a three-dimensional concrete block having a body portion 22 and a plurality of legs 23 that protrude radially from the body portion 22. The through-hole portion 21 is formed in at least one of the plurality of legs 23 in the three-dimensional block (block body 20), and the turbine generator 2 is placed inside the through-hole portion 21.
[0033] In the second embodiment, the three-dimensional block (block body 20) is configured to have a trunk portion 22 and four legs 23 that radially protrude from the trunk portion 22. One of the plurality of legs 23 in the three-dimensional block (block body 20) is formed with a through-hole portion 21 that penetrates the leg portion 23 in a direction (horizontal direction) perpendicular to the axial direction CL, and the turbine generator 2 is disposed inside this through-hole portion 21.
[0034] The turbine generator 2 is disposed inside a through-hole portion 21 formed in a three-dimensional block (block body 20), and generates electricity using a fluid W (see FIG. 5) flowing into the through-hole portion 21.
[0035] FIG. 7 is an explanatory diagram showing a state in which a plurality of blocks 1A according to the second embodiment are arranged and these blocks 1A are connected to a facility 6 by a power transmission line 5. As shown in FIG.
[0036] As shown in Fig. 7, a plurality of blocks 1A are appropriately arranged, and a turbine generator 2 of each block 1A is connected to a transmission line 5. Furthermore, a terminal of this transmission line 5 is connected to a facility 6 such as a substation.
[0037] The block 1A according to the second embodiment is used, for example, as a wave-dissipating block to be placed in a river or on a coast for the purpose of revetment.
[0038] The effects of the second embodiment will be described below.
[0039] (1) The block 1A according to the second embodiment includes a block main body 20 having a through-hole portion 21 and arranged in a coastal area, a sea area, a river area, or a discharge facility, and a turbine generator 2 arranged inside the through-hole portion 21 and generating electricity using a fluid W flowing into the through-hole portion 21.
[0040] In the second embodiment, a through-hole 21 is formed in the three-dimensional block (block body 20), and the turbine generator 2 is disposed inside this through-hole 21, so that the external shape of the block 1A is similar to that of a general three-dimensional block. Therefore, the function of the block 1A as a wave-dissipating block is not impaired, and there is no need to provide additional space for disposing the block 1A.
[0041] As described above, according to the second embodiment, it is possible to provide a block 1A that can maintain its original function as a wave-dissipating block and perform wave power generation using wave force acting on the concrete block or hydrodynamic power generation using hydrodynamic force.
[0042] (2) A power transmission line 5 is connected to the turbine generator 2 .
[0043] By connecting the terminal of this transmission line 5 to a facility 6 (see Figure 7) such as a substation, a power generation facility can be constructed that can perform wave power generation using wave power or hydrodynamic power generation using hydrodynamic power. Such a power generation facility can keep the initial cost and maintenance cost low compared to large-scale power generation facilities.

A through-hole 21 is formed in at least one of the plurality of legs 23 of the three-dimensional block (block body 20), and the turbine generator 2 is disposed inside the through-hole 21.
[0045] The block 1A configured in this manner can be used, for example, as a wave-dissipating block to be placed on a river or coast for the purpose of revetment. Because the turbine generator 2 is placed inside the through-hole 21 of this block 1A, the external shape of the block 1A is the same as that of a general wave-dissipating block. Therefore, the function of the block 1A as a wave-dissipating block is not impaired. Furthermore, because the external shape of the block 1A is the same as that of a general wave-dissipating block, it does not impair the scenery as compared to a general wave-dissipating block.

At least two of the plurality of legs 33 in the three-dimensional block (block body 30) are passed through the through-hole portion 31, and the turbine generator 2 is placed inside this through-hole portion 31.
[0050] In the third embodiment, a three-dimensional block (block body 30) is configured to have a trunk 32 and four legs 33 that radially protrude from the trunk 32. Each leg 33 of the three-dimensional block (block body 30) is formed with a hole 33b that extends from a tip end surface 33a of the leg 33 along the axial direction CL, and these hole portions 33b are connected in the trunk 32 to form the aforementioned through-hole 31.
[0051] In the third embodiment, the turbine generator 2 is disposed in the central portion (communicating portion) of the through-hole portion 31 formed in the trunk portion 32. However, this is not limited thereto, and the turbine generator 2 may be disposed on the opening portion 31a side of the through-hole portion 31 formed in the tip surface 33a of the leg portion 33.
[0052] The turbine generator 2 is disposed inside a through-hole 31 formed in a three-dimensional block (block body 30), and generates electricity using a fluid W (see FIG. 8) flowing into the through-hole 31.
