Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic winding and winding apparatus for a floating solar power generation apparatus, and a floating solar power generation apparatus including the same. 2. Description of the Related Art Generally,

The present invention relates to an automatic winding and winding device for a floating solar power generation apparatus and a floating solar power generation device including the same, and more particularly to an automatic winding and winding device for a floating type solar power generation apparatus which is connected between an anchor member and a floating body, The present invention relates to an automatic winding and winding apparatus for a floating solar power generation apparatus capable of automatically expanding and contracting a length thereof with a simple structure, and a floating solar power generation apparatus including the same.

The development and use of renewable energy is actively being done in conjunction with the energy problem. Among them, solar power generation is the most attracted to solar power generation because it is easy to install and operate, and it is possible to secure relatively stable power generation power, compared to other power generation methods using other energy, and the installation and operation proportion is also relatively large.

Such photovoltaic power generation is constituted based on a solar cell that receives solar light and generates electric power by a photoelectric effect, and a converter that converts generated electric power produced by the solar battery into AC power or converts it into direct DC power.

This photovoltaic power generation is relatively easy to install and operate compared to other power generation methods, but it can be installed quickly. However, since the amount of power generated is proportional to the installation area, it is inevitable to secure a site for installation and operation to be. However, it is not easy to secure sites that meet site conditions.

In order to avoid the difficulties and to secure the development site, the method of using the wall, roof and small scale of the building is used, and it is possible to secure some site. However, this also causes a difficulty in installing and designing a solar cell structure, resulting in an increase in the unit price of power generation, and the difficulty in maintenance due to the scarcity of a small power generation facility is increased. In order to solve this problem, it is being sought to install and operate water and marine facilities such as rivers, lakes and reservoirs.

It is anticipated that water and maritime space will be used as a farm or leisure space for only a part of the space.

However, contrary to this expectation, the fact that the photovoltaic power generation facilities are actually installed and operated in the waterfront and sea areas is very low. This is because solar power generation greatly changes in the amount of generated power due to factors such as variations in the incidence of sunlight, that is, changes in incident angle, generation of shadows such as clouds, and factors such as water or dust particles in the air. However, in the case of water or sea, there are many factors that inhibit the incident light amount of solar light on the ground surface, especially solar cell is fluctuated according to the waves of water surface or sea surface, and it is very difficult to maintain optimal generation amount. Further, it is assumed that a plurality of solar cell structures include the meaning of 'water' and 'sea' such as 'sleep', 'lake', 'river', 'reservoir' ) Is also a factor that makes operation of marine photovoltaic power generation difficult.

Particularly, in the floating solar power generation apparatus floating on the water surface, an external force due to a natural phenomenon such as a wave of the water surface or the sea surface (for example, an ocean current) or a typhoon acts on the water surface There is a problem in that when the support for supporting the solar cell module is fixed to the floating float, the supporting body and the float must be firmly fixed to the external force due to the natural phenomenon such as the wave of the sea surface or the sea surface or the typhoon . That is, in the case of the floating solar power generation device, there is a problem that the fixing force between the float and the support must be improved more than the ground mounted solar power generation device.

On the other hand, the floating solar power generation apparatus according to the related art is configured to fix the floating solar power generation device at a predetermined position on the water surface by connecting an anchor embedded in the floor underwater and a top plate of the float with wires.

In the case of the floating solar power generation apparatus according to the related art, it is preferable that the float of the floating solar power generation apparatus is directly or indirectly irradiated with a wave of water or sea surface (for example, ocean current), a typhoon, And a tensile force of a considerable size acts on the wire due to the external force, thereby shortening the lifetime of the connecting portion of the wire and / or float or the connecting portion of the wire connected to the anchor.

Also, in the conventional floating solar power generation apparatus, a method of loosely connecting a wire between an anchor and a float is also applied in order to reduce the stress caused by a tensile force acting on the wire, There has been a problem that the position on the water surface of the solar power generator can not be stably fixed.

Hereinafter, the operating state of the automatic winding and unwinding apparatus 300 according to the present invention will be described in more detail with reference to the drawings.

6A to 6C are schematic views showing an operating state of the floating solar power generation apparatus 1000 when an external force is applied to the floating solar power generation apparatus 1000 according to the present invention.

1, the automatic winding and unwinding apparatus 300 installed on the left side of the front portion of the floating body 100 is referred to as a first automatic winding and unwinding apparatus 300A, The automatic winding and unwinding apparatus 300 installed on the right side of the front portion is referred to as a second automatic winding and unwinding apparatus 300B and the automatic winding and unwinding apparatus 300 provided on the left side of the rear portion of the floating body 100, And the automatic winding and unwinding apparatus 300 provided on the right side of the rear portion of the floating body 100 is referred to as a fourth automatic winding and unwinding apparatus 300D. 1, a wire W connected to each of the first automatic winding and wringing apparatus 300A to the fourth automatic winding and wringing apparatus 300D is referred to as a first wire W1 through a fourth wire W1 W4).

6A and 6B, an external force such as wind or current may be applied to the floating solar power generation apparatus 1000 from the left front to the right rear direction to the floating solar power generation apparatus 1000 at the initial installation position have.

At this time, if the first automatic winding and unwinding apparatus 300A through the fourth automatic winding and unwinding apparatus 300D are not provided as in the prior art, the first wire W1 and the third wire W3 are moved by the action of an external force, The lifetime of the first wire W1 and the third wire W3 and the life of the first wire W1 and the third wire W3 in the anchor member 200 and / The tensile force of the second wire W2 and the fourth wire W4 is significantly reduced and the second wire W2 and the fourth wire W4 are loosened So that it is difficult to stably maintain the floating solar power generation apparatus 1000 in a specific position.

However, since the present invention includes the automatic winding and unwinding device 300, the problems of the prior art can be solved. Specifically, when the external force is applied, the first and second automatic reel-up and rewind apparatus 300A and the reel member 330 of the third automatic reel-up and rewinder apparatus 300C rotate in the direction opposite to the direction of the elastic restoring force of the torsion spring The wire W is wound further in the second rotation direction to increase the elastic restoring force stored in the torsion spring and at the same time the tensile force applied to the wire W is relaxed in a certain range, State.

In contrast to FIG. 6C, when the water level falls due to a drought or the like, the buoyancy is reduced (due to the volume reduction of the floating body 100 immersed in water), so that the first to fourth wires W1- The first wire W1 to the fourth wire W4 may be loosened, and as a result, there is a concern that the position fixing performance of the floating solar battery 1000 may deteriorate.

However, since the present invention includes the automatic winding and unwinding device 300, the problems of the prior art can be solved. Specifically, when the external force such as the additional buoyancy is applied, the reel members 330 of the first to third automatic reel-up and rewind apparatus 300A to the fourth automatic reel-up and reel-off apparatus 300D are operated by the elastic restoring force of the torsion spring And the wire W is further wound to increase the elastic restoring force stored in the torsion spring while at the same time relaxing the tensile force applied to the wire W in a certain range, W) can be maintained in a tight state.

Also, even when the water level falls due to a drought or the like, the reel members 330 of the first to third automatic reel-up and reel-off devices 300A to 300D are elastically restored to the elastic restoring force of the torsion springs The wire W is wound in the first rotation direction, which is the acting direction of the wire W, and the elasticity restoring force stored in the torsion spring is reduced, so that the wire W can be maintained in a taut state.

According to the foregoing, the present invention can reduce the tensile stress acting on the wire connecting between the anchor member and the floating body, whereby the connecting portion of the anchor member connected to the wire and / or the wye, It is possible to improve the life of the device.

In addition, according to the present invention, a predetermined tension is maintained so that the wire connecting the anchor member and the floating body is always straight, so that the installation position of the floating solar power generation device can be maintained within a predetermined range at the initial installation position, It is possible to minimize the deterioration of the solar power generation efficiency due to the disconnection of the installation position of the photovoltaic device.

Further, the present invention is configured to automatically wind and wind a wire with a mechanical structure using a torsional elastic means, so that a simple structure can be applied without using a separate driving means, It is possible to easily and automatically adjust the length of the wire connecting the anchor member and the floating body to correspond to the direction of action of the external force. Thus, the present invention can minimize the rise in manufacturing cost while automatically adjusting the length of the wire.
