As shown in FIG. 5, even when the fixing position of the mooring member 80 with the floating body 10 is located below the water surface, the mooring member 80 sinks underwater by its own weight due to the floating portion 82 </ b> A of the mooring member 80. Can be suppressed. Thereby, compared with the conventional mooring member, the electric power generation system 1 becomes difficult to incline with respect to the water surface. Further, for example, even when the user pulls the mooring member 80, the resistance of water to the mooring member 80 can be suppressed.

(effect)
As described above, according to the first embodiment, since the mooring member 80 is formed so that at least a part of the mooring member 80 can float on the water surface, the mooring member 80 sinks into water under its own weight. Can be suppressed. Thereby, compared with the conventional mooring member, since the electric power generation system 1 becomes difficult to incline with respect to the water surface, the attitude | position of this electric power generation system 1 becomes easy to become flat with respect to the water surface. Therefore, for example, the influence on the power generation efficiency of the power generation system 1 (specifically, the rotation speed of the propeller 40 is reduced by changing the angle of the propeller 40) can be suppressed. Further, for example, when the user pulls the mooring member 80, the resistance of water to the mooring member 80 can be suppressed, so that the mooring member 80 can be easily handled.

  The mooring member 80 is a mooring member main body 81 and a floating portion 82A that substantially covers at least a part of the mooring member main body 81, and floats at least a part of the mooring member 80 that can float on the water surface. Therefore, the mooring member 80 can be manufactured with a simple structure, and the manufacturability of the mooring member 80 can be improved.

  Further, the anchoring member 80 is floated on the propeller 40 so that the anchoring position of the anchoring member 80 with the floating body 10 is positioned on the axial extension line of the shaft 41 substantially along the Y direction. Since it is fixed to 10, the flapping of the floating body 10 due to the rotation of the propeller 40 can be reduced, and the stability when the power generation system 1 is moored can be improved.

[Embodiment 2]
Next, a second embodiment will be described. This form is the form which provided the 1st flowing water direction change means in the mooring member. In addition, about the component similar to Embodiment 1, the same code | symbol or name as used in Embodiment 1 is attached | subjected as needed, and the description is abbreviate | omitted.

(Configuration-power generation system)
The power generation system 1 according to the second embodiment is configured in substantially the same manner as the power generation system 1 according to the first embodiment.

(Configuration-mooring structure)
Next, the mooring structure in the power generation system configured as described above will be described. FIG. 6 is a perspective view showing a mooring member according to the second embodiment. FIG. 7 is a perspective view showing a modification of the mooring member according to the second embodiment. As shown in FIG. 6, the mooring structure 160 according to the second embodiment is configured in substantially the same manner as the mooring structure 60 according to the first embodiment. However, about the structure of the mooring member 80, the device shown below is given.

(Configuration-Mooring structure-Configuration of mooring member)
Regarding the configuration of the mooring member 80, as shown in FIG. 6, the mooring member 80 includes a mooring member main body 81 and a floating portion 82B. Here, the floating portion 82B is disposed so as to accommodate a part of the mooring member main body 81 (for example, a part of the mooring member main body 81 other than the Y-shaped bifurcated portion). It is connected to 81 by a fixing tool (for example, a resin binding tool or the like).

  The floating portion 82B is provided with a first flowing direction changing portion 83. The first flowing water direction changing unit 83 indicates the direction of flowing water that passes through the first flowing water direction changing unit 83, and the foreign matter is the power generation system 1 (more specifically, the floating body 10, the connecting unit 20, the hydrofoil 30. , Propeller 40 etc.) is a first flowing water direction changing means for changing the direction so as not to accumulate. Here, “flowing water that passes through the first flowing water direction changing unit 83” means substantially along a part of the first flowing water direction changing unit 83 after colliding with the first flowing water direction changing unit 83. It means flowing water that flows toward the downstream side (the same applies to the meaning of “flowing water that passes through the foreign substance passage suppressing unit 84 according to Embodiment 3” described later). The first flowing direction changing portion 83 is formed of, for example, the same material as the floating portion 82B, and is arranged at the upstream end portion of the floating portion 82B (or the downstream end portion of the floating portion 82B). It is fixed to the floating portion 82B by a fixture or welding.

  Here, about the shape of the 1st flowing direction change part 83, for example, the direction of the flowing water which passes the said 1st flowing direction change part 83 is changed into the direction which does not flow between floating bodies 10a and 10b. It is desirable to be formed in a shape capable of. Specifically, as shown in FIG. 6, the first flowing water direction changing unit 83 is a substantially triangular prism-like body so that the length in the X direction of the first flowing water direction changing unit 83 becomes longer as it goes downstream. (More specifically, the first flow direction changing portion 83 has a planar shape that is an isosceles triangle having a base that is substantially parallel to the X direction. A flow direction changing portion 83 is formed). In this case, the portion that receives the resistance of the flowing water in the first flowing water direction changing unit 83 (specifically, the plane of the first flowing water direction changing unit 83 among the side parts of the first flowing water direction changing unit 83). With respect to the shape of the side corresponding to two equal sides in the shape, for example, the shape (specifically, the second level) that the flowing water colliding with the resistance receiving portion of the flowing water does not flow between the floating bodies 10a and 10b. Among the side portions of one flowing water direction changing portion 83, the angle and size of the side portions corresponding to the two equal sides are set.

  In the second embodiment, the first flowing water direction changing unit 83 is described as being formed of a substantially triangular prism, but the present invention is not limited to this. For example, as shown in FIG. 7, the first flowing water direction changing portion 83 may be formed of a plate-like body having a substantially inverted L-shaped longitudinal section. Specifically, the inverted L-shaped horizontal piece in the first flowing water direction changing portion 83 contacts the floating portion 82B, and the inverted L-shaped vertical piece is upstream of the inverted L-shaped horizontal piece. This first flowing direction changing portion 83 is formed so as to be connected to the end portion on the side (note that the phantom line shown in FIG. 17 indicates the flow of flowing water).

  With such a configuration, the direction of the flowing water can be changed so that the flowing water passing through the first flowing water direction changing unit 83 does not flow between the floating bodies 10a and 10b.

(Function of mooring structure)
The function of the mooring structure 160 configured as described above will be described. In addition, about the function of this mooring structure 160, the function is demonstrated only about a different part from Embodiment 1 mentioned above.

  As shown in FIG. 6, since the first flowing direction changing portion 83 is provided in the floating portion 82B of the mooring member 80, the flowing water passing through the first flowing direction changing portion 83 has a locus shown below. It flows toward the downstream side while tracing. Specifically, this running water collides with the first flowing direction changing unit 83 and then flows toward the downstream side so as to substantially follow the portion of the first flowing direction changing unit 83 that receives the resistance of flowing water ( The phantom line shown in FIG. 6 shows the flow of running water). Next, the flowing water passes through the first flowing water direction changing unit 83, then flows between the floating body 10 and the revetment of the water channel, and passes through the floating body 10 through the mutual. Such flowing water can prevent the flowing water from flowing between the floating bodies 10 a and 10 b, and can prevent foreign matter from accumulating in the power generation system 1.

(effect)
As described above, according to the second embodiment, the direction of the flowing water passing through the first flowing direction changing unit 83 is changed to the direction in which the foreign matter does not accumulate in the power generation system 1 in the floating portion 82B of the mooring member 80. Since the 1 flowing water direction change part 83 was provided, it can suppress that a foreign material accumulates in the electric power generation system 1 by changing the direction of the said flowing water. Therefore, for example, the number of maintenance work operations can be reduced as compared with the foreign substance passage suppressing unit 84 according to the third embodiment described later.

[Embodiment 3]
Next, Embodiment 3 will be described. This form is a form in which the mooring member is provided with foreign matter passage suppressing means. In addition, about the component similar to Embodiment 2, the same code | symbol or name as used in Embodiment 2 is attached | subjected as needed, and the description is abbreviate | omitted.

(Configuration-power generation system)
The power generation system 1 according to the third embodiment is configured in substantially the same manner as the power generation system 1 according to the second embodiment.

(Configuration-mooring structure)
Next, the mooring structure in the power generation system 1 configured as described above will be described. FIG. 8 is a perspective view showing a mooring member according to the third embodiment. FIG. 9 is a perspective view showing a modification of the mooring member according to the third embodiment. As shown in FIG. 8, the mooring structure 260 according to the third embodiment is different from the constituent elements of the mooring structure 160 according to the second embodiment in that a foreign matter passage suppressing unit 84 is used instead of the first flowing water direction changing unit 83. It is configured as.

(Configuration-mooring structure-configuration of foreign matter passage suppression part)
The foreign object passage suppression unit 84 is foreign matter passage suppression means for suppressing the passage of foreign matter. The foreign substance passage suppressing portion 84 is formed of, for example, the same material as that of the floating portion 82B, and is disposed at the upstream end of the floating portion 82B. In addition, the foreign matter passage suppressing portion 84 includes a filter portion 84a and a support portion 84b. Here, although the formation method of the foreign material passage suppression portion 84 is arbitrary, for example, in order to improve the manufacturability of the foreign material passage suppression portion 84, the filter portion 84a and the support portion 84b are formed by integral molding. Is applicable.

  The filter part 84a is for making the foreign substance contained in the flowing water which passes the foreign substance passage suppression part 84 remain in the said filter part 84a. The filter portion 84a is formed in a substantially comb-like body with a space therebetween in a plane orthogonal to a direction from upstream to downstream (corresponding to the Y direction in FIG. 8). More specifically, the filter portion 84a is formed in a linear shape substantially along the X direction, and is formed so that a substantially comb-shaped tooth portion in the filter portion 84a projects downward ( The same applies to the configuration of the second flowing water direction changing unit 85 of the fourth embodiment described later). In addition, as for the shape of the substantially comb-shaped tooth portion in the filter portion 84a, for example, the direction of the flowing water that passes through the foreign matter passage suppressing portion 84 is changed even after the flowing water collides with the substantially comb-shaped tooth portion. It can be maintained in the forward direction, and is formed in a shape that allows foreign matter contained in the running water to remain on the substantially comb-shaped tooth portion (specifically, described later) Compared to the second flowing water direction changing unit 85 according to the fourth embodiment, the number of gaps of the substantially comb-shaped tooth portion is increased, and the width of the substantially comb-shaped tooth portion is reduced. It is formed).

  The support portion 84b is for supporting the filter portion 84a. The support portion 84b is formed of a substantially plate-like body, and is disposed so as to protrude from the floating portion 82B toward the filter portion 84a. Further, the upstream end portion of the support portion 84b is connected to the substantially comb-shaped tooth base portion of the filter portion 84a, and the downstream end portion of the support portion 84b is fixed to the floating portion 82B. It is fixed by welding or the like.

  In the third embodiment, the filter portion 84a of the foreign matter passage suppressing portion 84 has been described as being formed in a straight line substantially along the X direction, but is not limited thereto. For example, as shown in FIG. 9, the filter portion 84 a is substantially shaped so that the center portion of the filter portion 84 a is positioned upstream (or downstream) from both ends of the filter portion 84 a in the X direction. (More specifically, the number of teeth of the substantially left side of the filter portion 84a and the number of teeth of the right side of the substantially square shape) Are formed so that they are substantially the same).

  With such a configuration, the foreign matter contained in the flowing water passing through the foreign matter passage suppressing portion 84 can be retained in the filter portion 84a, and foreign matter can be prevented from flowing between the floating bodies 10a and 10b.

(Function of mooring structure)
The function of the mooring structure 260 configured as described above will be described. In addition, about the function of this mooring structure 260, the function is demonstrated only about a different part from Embodiment 2 mentioned above.

  As shown in FIG. 8, since the foreign matter passage suppressing portion 84 is provided in the floating portion 82 </ b> B of the mooring member 80, the flowing water passing through the foreign matter passage suppressing portion 84 is directed downstream while following the locus shown below. Flowing. Specifically, this flowing water collides with the filter portion 84a of the foreign matter passage suppressing portion 84, and then flows toward the downstream side through a gap between the substantially comb-shaped tooth portions in the filter portion 84a.

  At this time, the direction of the flowing water maintains the state before the collision even after the flowing water collides with the substantially comb-shaped tooth portion in the filter portion 84a. Moreover, the foreign material contained in this running water will remain in this filter part 84a.

  Next, the flowing water passes through the foreign substance passage suppressing unit 84, then flows between the floating bodies 10a and 10b, and passes through the floating body 10 through the mutual.

  Such a flow of flowing water can prevent foreign matter from flowing between the floating bodies 10 a and 10 b, and can prevent foreign matter from accumulating in the power generation system 1.

(effect)
As described above, according to the third embodiment, since the foreign matter passage suppressing portion 84 that suppresses the passage of foreign matter is provided in the floating portion 82B of the mooring member 80, the foreign matter is prevented from passing through by suppressing the passage of foreign matter. It can suppress that it deposits on. Therefore, for example, compared with the 1st flow direction change part 83 which concerns on Embodiment 2, accumulation of a foreign material can be suppressed reliably.

[Embodiment 4]
Next, a fourth embodiment will be described. This form is the form which provided the 2nd flowing water direction change means in the mooring member. In addition, about the component similar to Embodiment 2, the same code | symbol or name as used in Embodiment 2 is attached | subjected as needed, and the description is abbreviate | omitted.

(Configuration-power generation system)
The power generation system 1 according to the fourth embodiment is configured in substantially the same manner as the power generation system 1 according to the second embodiment.

(Configuration-mooring structure)
Next, the mooring structure in the power generation system 1 configured as described above will be described. FIG. 10 is a perspective view showing a mooring member according to the fourth embodiment. 11 to 13 are perspective views showing modifications of the mooring member according to the fourth embodiment. As shown in FIG. 10, the mooring structure 360 according to the fourth embodiment is different from the constituent elements of the mooring structure 160 according to the second embodiment in the second flowing water direction instead of the first flowing water direction changing unit 83. The change unit 85 is configured.

(Configuration-mooring structure-configuration of second flowing water direction change unit)
The second flowing water direction changing unit 85 indicates the direction of flowing water flowing into the power generation system 1 (mainly the direction of flowing water flowing between the floating bodies 10a and 10b), and the flowing water is the second flowing water direction changing unit 85. The second flowing water direction changing means for changing from the upstream side to the downstream side of the second flowing water direction changing unit 85 to change the flow direction into the power generation system 1. The second water flow direction changing unit 85 is formed of, for example, the same material as that of the floating part 82B, and is disposed at the upstream end of the floating part 82B.

  Here, the shape of the second flowing water direction changing portion 85 is formed in a substantially comb-shaped body at intervals in a plane orthogonal to the Y direction. Moreover, about the shape of the substantially comb-shaped tooth portion in the second flowing water direction changing unit 85, for example, after the flowing water collides with the substantially comb-shaped tooth portion, the direction of the flowing water flowing into the power generation system 1, It is possible to flow through the gaps of the substantially comb-shaped tooth portions so as to substantially follow the outer edges of the substantially comb-shaped tooth portions, and then change the direction to flow between the floating bodies 10a and 10b, and It is formed in a shape that allows foreign matters larger than a predetermined size to stay (specifically, compared to the foreign matter passage suppressing portion 84 according to the third embodiment, this substantially comb-shaped tooth portion. And the width of the substantially comb-shaped tooth portion is increased).

  For fixing the second flowing water direction changing portion 85, for example, the substantially comb-shaped tooth base portion in the second flowing water direction changing portion 85 is fixed to the floating portion 82B by a fixture or welding. Yes.

  In the fourth embodiment, it has been described that the second flowing water direction changing unit 85 is formed so that the substantially comb-shaped tooth portion of the second flowing water direction changing unit 85 projects downward. It is not limited to this. For example, as shown in FIG. 11, the second flowing water direction changing unit 85 may be formed so that the substantially comb-shaped tooth portion of the second flowing water direction changing unit 85 projects upward. Or as shown in FIG. 12, the said 2nd water flow direction change part 85 may be formed so that the substantially comb-shaped tooth | gear part in the 2nd water flow direction change part 85 may protrude above and below.

  In the fourth embodiment, the second flowing water direction changing unit 85 increases the speed of flowing water flowing into the power generation system 1, and foreign substances having a predetermined size or more are supplied to the second flowing water direction changing unit 85. Although it demonstrated that it was formed in the shape which can be kept, it is not restricted to this. For example, the second flowing water direction changing unit 85 may be formed in a shape that simply increases the speed of flowing water flowing into the power generation system 1. Specifically, as shown in FIG. 13, the flowing water that has collided with the upstream portion of the second flowing water direction changing unit 85 wraps around the downstream portion via the outer edge portion, thereby causing the flowing water to flow. The second flowing direction changing portion 85 is formed of a substantially cylindrical body so that the speed can be effectively increased (the phantom line shown in FIG. 13 indicates the flow of flowing water). In this case, although the formation method of the 2nd flowing water direction change part 85 is arbitrary, for example, as shown in FIG. 13, the 2nd flowing water direction change part 85 and the floating part 82B are formed integrally. Is applicable.

  With such a configuration, the direction of the flowing water that passes through the second flowing water direction changing unit 85 can be changed so that the speed of the flowing water flowing into the power generation system 1 is increased.

(Function of mooring structure)
The function of the mooring structure 360 configured as described above will be described. In addition, about the function of this mooring structure 360, the function is demonstrated only about a different part from Embodiment 2 mentioned above.

  As shown in FIG. 11, since the second flowing water direction changing portion 85 is provided in the floating portion 82B of the mooring member 80, the flowing water flowing into the power generation system 1 is directed toward the downstream side while following the locus shown below. Flowing. Specifically, the flowing water collides with the substantially comb-shaped tooth portion in the second flowing water direction changing portion 85, and then the substantially comb-shaped tooth so as to substantially follow the outer edge of the substantially comb-shaped tooth portion. It flows toward the downstream side through the gap of the part.

  Here, for example, when the flow rate of the flowing water flowing through the flow channel and the water level of the flow channel are constant, and the width of the flow channel becomes narrower, the relationship of the speed of the flowing water = flow rate / flow channel area From the equation, it is clear that the speed of this running water is faster. Based on this, when the flowing water flowing into the power generation system 1 passes through the second flowing water direction changing unit 85, the width of the flow path is narrowed by the substantially comb-shaped tooth portion in the second flowing water direction changing unit 85. Therefore, the speed of the flowing water that has passed through the second flowing water direction changing unit 85 is increased. Moreover, after flowing water collides with the substantially comb-shaped tooth part in the 2nd flowing water direction change part 85, a predetermined or more foreign material will remain in the substantially comb-shaped tooth part in the 2nd flowing water direction change part 85. .

  Next, the flowing water passes through the second flowing water direction changing unit 85, then flows between the floating bodies 10 a and 10 b, and passes through the power generation system 1 through the mutual.

  Such a flow of flowing water can increase the speed of flowing water flowing between the floating bodies 10a and 10b. For example, the rotation speed of the propeller 40 can be increased. In addition, the substantially comb-shaped tooth portion in the second flowing water direction changing unit 85 prevents foreign matter having a size larger than a predetermined value from staying in the substantially comb-shaped tooth portion, and thus prevents the foreign matter from accumulating on the power generation system 1. It becomes possible to do.

(effect)
As described above, according to the fourth embodiment, the direction of the flowing water flowing into the power generation system 1 into the floating portion 82B of the mooring member 80 is changed from the upstream side of the second flowing water direction changing unit 85 to the second flowing water. Since the second flowing water direction changing unit 85 that changes to the direction of flowing into the power generation system 1 around the downstream side of the flowing water direction changing unit 85 is provided, the speed of the flowing water is increased by changing the direction of the flowing water. Can be made. Thereby, the rotation speed of the propeller 40 can be increased, and the power generation amount of the power generation system 1 can be improved.
