Rotating floating solar power plant including floating table and rotating shaft

[0001] The present invention relates to a rotary floating solar power plant including a floating table and a rotation shaft, and more particularly, to a rotary floating solar power plant including a floating table and a rotation shaft that rotates with respect to a turntable floating on water so that solar modules around the turntable rotate along the sun.

[0002] In general, solar power generation is a method of converting sunlight into electricity using solar cells, which are made of semiconductor materials and receive sunlight to generate electricity.

[0003] These solar power generation systems consist of modules made up of solar cells that generate electricity through the photovoltaic effect when sunlight hits them, batteries, and power conversion devices.

[0004] Solar power generation configured in this way has the advantage of being easy to install and operate and quick to install compared to other power generation methods, but since the amount of power generated is proportional to the installation area, securing a site for installation and operation is essential to secure the desired amount of power generated, but securing a site that meets the location conditions is not easy.

[0005] In order to secure land that can avoid this situation, it has become possible to secure some land by using the walls, roofs, and small-scale bare land of buildings, but this also causes difficulties in installing solar cell structures and designing them, which leads to an increase in the unit price of power generation, and there is a problem that the difficulty in maintenance increases due to the proliferation of small-scale power generation facilities.

[0006] To address this, methods are being explored for installing and operating solar power generation facilities on water surfaces such as lakes, reservoirs, dams, public waters, and the ocean. Since only a portion of the water surface is used as aquaculture farms or leisure spaces, it is expected that a vast area compared to land can be secured as operating space for solar power generation facilities.

[0007] Typically, a rotary floating solar power generation device is a structure in which the rotation axis rotates around a vertically erected support, as disclosed in Korean Patent Publication Nos. 10-1744254, 10-1013339, and 10-1056607.

[0008] This structure is problematic for widespread use because it is expensive to install and therefore not economical in places where a breakwater is created in the sea or where a dam or reservoir with deep water is created.

[0009] In addition, in these prior technologies, when a large change in water level occurs, the power generation efficiency is bound to decrease due to shading (shadowing) from vertically erected columns, and the shared water surface with strong currents is at a high risk of overturning when a strong current occurs on soft ground, making it difficult to guarantee safety.

[0010] The present invention is intended to solve the above problems, and provides a floating solar power plant including a floating table and a rotational axis, in which a plurality of wires are connected from the upper portion of a rotatable rotational axis at the center of a floating table to solar power generation modules floating around the table, and a driving unit capable of rotating the rotational axis is provided on the table side, so that the solar power generation modules around the table can stably rotate along the rotational axis following the sun even in areas with deep water or large changes in water level.

[0082] The rotary support table (151), the power generation rotary shaft (153) and the third shackle (155) have the same structure as the center table (10), the center rotary shaft (50) and the first shackle (54), and a detailed description thereof is omitted.

[0083] The floating body (90) for connecting the power generation unit is located around the periphery of the rotary support table (151) and is connected to the solar power generation unit (80) around the periphery by a universal joint.

[0084] The third mooring section is composed of the same technical configuration as the first mooring section and limits the rotation of the rotary support table (151).

[0085] One rotary drive rope (160) is connected at one end to one first shackle (54) and extends along the circumference of one solar power generation unit (80) to be connected to second shackles (92) and the other end is connected to another first shackle (54) so ​​that one end and the other end intersect each other.

[0086] Accordingly, when the center rotation axis (50) rotates, the solar power generation unit (80) rotates in the opposite direction to the rotation direction of the center rotation axis (50).

[0087] One rotary drive rope (160) may be connected to only one solar power generation unit (80), or may be extended in a figure 8 shape to rotate a pair of solar power generation units (80) that are symmetrically arranged with a center table (10) in between.

[0088] By means of the above connection structure, the solar power generation unit can be rotated in the opposite direction to the rotational direction of the center rotation axis (50).

[0089] The second mooring unit (120) is equipped with a plurality of second anchors (123), a plurality of second mooring ropes (126), a plurality of tension control winches (119), and first and second anti-entanglement weights (131, 133).

[0092] A tension control winch (129) connected to at least one second mooring rope (126) is installed in each solar power generation unit.

[0093] Meanwhile, as illustrated in FIG. 7, a rotary floating solar power plant (1") including a floating table and a rotary shaft according to a third embodiment of the present invention may include a center table (10), a center rotary shaft (50) having a first shackle (54) mounted on the upper portion, a rotary drive unit (70), a first mooring unit (110), one solar power generation unit (80) radially spaced from the center table (10), one power generation unit rotation guide unit (150), one rotary drive rope (160), and a second mooring unit (120).

[0094] Unlike the drawing, the rotary drive rope (160) may be connected to different first shackles (54) spaced apart in the circumferential direction so that one side and the other side do not intersect each other.

[0095] Meanwhile, although not shown, a rotary floating solar power plant including a floating table and a rotation shaft according to the fourth embodiment of the present invention has the same structure as the second embodiment of the present invention, except for a number of power generation unit rotation guide units.

[0096] A plurality of power generation unit rotation guide units are positioned at the center of the solar power generation unit (80) and are connected to a rotation table by a universal joint so as to rotate together with the solar power generation units, a rotation support shaft mounted at the center of the rotation table and having rotation restricted, and a third retaining member restricting rotation of the rotation support shaft.

[0097] The rotary table and the rotary support shaft have the same structure as the center table (10) and the center rotary shaft (50), but the rotary table has a wider width than the center table (10) and can be directly connected to the solar power generation unit (80) by a universal joint.

[0098] Although not shown, the third mooring section may be equipped with a plurality of third anchors positioned below the solar power generation section (80), and a plurality of third mooring ropes extending from each anchor and intersecting each other in a pair of 'X' shapes and connected to the lower portion of the rotation support shaft.

[0099] The present invention described above has been described with reference to an example shown in the drawings, but this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible.

[0100] Therefore, the true scope of technical protection of the present invention should be determined by the technical idea of ​​the appended patent claims.
