Description

[Technical Field]

[0001] The present invention relates to a flood prevention device and a method for reimbursing the construction costs of a flood prevention device. [Background technology]

[0002] Due to global warming, the amount of rainfall that falls at one time due to torrential rain is increasing, and rivers are flooding almost every year due to overflowing water or the collapse of levees. One of the countermeasures against river flooding is to raise the height of levees (for example, Patent Document 1). [Prior art documents] [Patent documents]

[Figure 4] 1 shows a side view of a flood prevention device with a generator set 10 according to a second modified embodiment of the present invention. [Figure 5] 1 shows a plan view of a flood prevention device with a generator 10 according to a second modified embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0007] FIG. 1 shows a side view of a flood prevention device with a power generator 10 according to an embodiment of the present invention. As shown in the figure, levee 1 has a slope 3 on the river 2 side and a crest 4. The crest 4 can be used as a road, a promenade, or the like. The flood prevention device with a power generator 10 is installed along the flow direction (longitudinal direction) of river 2. It is preferable to install it on the crest 4, particularly on the side closest to river 2. In the figure, the flood prevention device with a power generator 10 is installed on levee 1 on both sides of river 2, but it may also be installed on only one side.

[0008] The flood prevention device with power generation device 10 has a water stop structure 20, a plurality of poles 30, a wind power generator (wind turbine) 40, and a solar panel 50.

[0009] The pillars 30 are provided spaced apart in the longitudinal direction on the water blocking structure 20. A wind turbine 40 is provided on each pillar 30, and rotates around the pillar 30 as an axis to generate electricity.

[0010] The solar panel 50 is fixed to the adjacent pillar 30. The solar panel 50 should be fixed in a direction that increases power generation efficiency (for example, upward to the right (50a) or downward to the right (50b) in FIG. 1). As shown in the figure, the solar panel 50 may be fixed by a solar panel fixing member 51 provided on the pillar 30.

[0011] Electricity generated by wind turbines 40 and / or solar panels 50 is transmitted via power lines (not shown). The profits from selling this electricity can be used to reimburse the installation costs of flood prevention device with power generator 10. A power storage device and a power transmission management device may be added to flood prevention device with power generator 10 so that electricity can be transmitted during demand hours.

[0012] In the above embodiment of the flood prevention device with power generator 10, by installing the water stop structure 20 on the crest 4 of the levee 1, it is possible to obtain the same effect as raising the levee 1. Furthermore, because the electricity generated by the wind turbines 40 and solar panels 50 is transmitted to the outside, the installation costs of the flood prevention device with power generator 10 can be reimbursed with profits from selling the generated electricity. This effectively reduces the installation costs. Even after the costs have been reimbursed, income from sales can be expected.

[0013] 2 and 3 show a first modified embodiment of a flood prevention device with a power generator 10 of the present invention. The first modified embodiment of the flood prevention device with a power generator 10 is installed on a narrow river, such as in a town. As shown in the figures, in the modified embodiment of the flood prevention device with a power generator 10, water stop structures 20 are installed on both sides of the river 2. Therefore, the poles 30 and wind turbines 40 are lined up on both sides of the river, as shown in FIG. 3. The solar panels 50 are fixed to the poles 30 on both sides of the river 2. They are also suspended above the river 2. This stabilizes the posture of the solar panels 50.

[0014] 4 and 5 show a second modified embodiment of the flood prevention device with a generator 10 of the present invention. The second modified embodiment of the flood prevention device with a generator 10 is installed in a large river with a wide crest 4 of the levee 1. Although the figures show only one side of the levee 1, it may be installed on both sides.

[0015] The second modified embodiment of the flood prevention device with power generator 10 is installed on a foundation 60 that is installed on the top 4. As shown in the figure, the water stop structure 20 is installed at one end of the width direction of the foundation 60 (left and right direction in Figure 4). It is preferable to install it on the side closer to the river 2. The other end of the foundation 60 should also have multiple pillars 30a in the same number as the pillars 30. As with the pillars 30, each pillar 30a should also have a wind turbine 40.

[0016] The solar panel 50 is fixed to the pillars 30, 30a on both sides and suspended above the base 60. As shown in Figure 4, the solar panel 50 may be suspended at an angle in the width direction of the base 60 to improve power generation efficiency.

[0017] If the wind power generator 40 is installed below the solar panel 50 on the side where the solar panel 50 is higher, or above the solar panel 50 on the side where the solar panel 50 is lower, the space above and below the solar panel 50 can be used effectively.

[0018] The flood prevention device with power-generating device 10 may further include a beam 31 connecting adjacent columns 30, 30a in the longitudinal direction of the base 60. The beam 31 may be provided above the solar panel 50 on the side where the solar panel 50 is higher, and below the solar panel 50 on the side where the solar panel 50 is lower.

[0019] Each beam 31 may have a second windmill (second wind power generator) 40a (FIG. 5). The second windmill 40a rotates around the beam 31 as an axis to generate electricity (FIG. 4).

[0020] If the wind turbines 40, 40a are installed high enough, the top 4 (foundation 60) can be used as a road or a promenade. By installing the wind turbine 40 on the additional pillar 30a and the second wind turbine 40a on the beam 31, an increase in power generation is expected. In addition, by installing the watertight structure 20 and pillars 30 on the foundation 60, construction work on the embankment 1 itself, such as digging holes, is not required.

[0021] The dimensions, shapes, arrangements, numbers, materials, etc. of the flood prevention device with power generator and its elements described in the above embodiment are merely examples, and other embodiments are possible. For example, the flood prevention device with power generator 10 can be installed around an industrial park or residential area. [Explanation of symbols]
