Description

Mooring and rotating device of floating solar PV system

The present invention relates to a mooring and rotating apparatus for a floating solar photovoltaic power generation system. More particularly, the present invention relates to a mooring and rotating apparatus for a floating solar photovoltaic power generation system in which a float on which a solar cell module is installed is installed on a water surface of a reservoir, To a mooring and rotating apparatus of a floating solar photovoltaic power generation system that allows a solar cell module to rotate in response to a fluctuation of the sun position while maintaining an arrangement state of the solar cell with respect to the sun, .

Generally, photovoltaic power generation is a power generation method that converts sunlight to electric power by a solar cell, and a solar cell made of a semiconductor material receives solar light to generate electricity.

Such solar power generation is composed of a solar cell module, a battery, and a power conversion device that generates electricity by photoelectric effect when sunlight is incident.

Although the solar power generation system has the advantages of easy installation and operation and quick installation compared with other power generation systems, the generation amount is proportional to the installation area. Therefore, in order to secure the desired power generation amount, It is inevitable, however, that it is not easy to secure sites that meet site conditions.

Although it is possible to secure some sites through the use of walls, roofs, and small meadows of a building to secure a site for such a situation, it is difficult to design and install solar cell structures. And the difficulty of maintenance due to the scarcity of small-scale power generation facilities has been a problem.

In order to solve this problem, there is a plan to install and operate a photovoltaic power generation system in a waterfront such as a lake, a reservoir, a dam, and a shared water surface, and only a part of the water is used as a farm or a leisure space. It is anticipated that it will be possible to secure an enormous area as an operating space for photovoltaic power generation facilities.

As a conventional technique, Patent Document 1 (Korean Utility Model Application No. 20-2007-0000044) discloses a solar cell module which is made of wood, styrofoam, or plastic having a low specific gravity in order to make a solar cell module, And a solar photovoltaic panel having a structure in which a module necessary for solar power generation is combined with the solar photovoltaic power generation system.

However, in the conventional aquarium photovoltaic generation apparatus as in Patent Document 1, the floating body can not be moored at the installation position of the water surface, and the position easily changes due to external force such as wind or water wave, There arises a problem that it collides with a separate structure to cause its own breakage or breakage of the associated installation structure.

Further, it is difficult to cope with a change in the incident angle of sunlight due to the change of the position of the sun, so that the solar radiation amount of the sunlight is reduced, and the power generation efficiency is lowered.

On the other hand, Patent Document 2 (Korean Patent Registration No. 10-1162473) discloses, as a prior art, a float 1 formed to float on the water surface as an area of a predetermined size, A sunlight generating facility 2 provided on the upper surface of the float 1 and a sheave 3 provided at a constant interval on the periphery of the float 1 and a sheath 1 and the other end of the support rope 4 is connected to an anchor 5 of a weight mounted on the water floor and the other end of the support rope 4 is connected to a support And an adjustable support rope connected to the weight weight 6 for the water.

However, in the conventional aquatic photovoltaic power generation system as in Patent Document 2, when the fluctuation range of the water level such as a lake, a reservoir, a dam, or a shared water surface due to heavy rain or drought due to an abnormal temperature phenomenon increases, Due to the mooring system including the anchor and the weight, the position and arrangement direction of the aquatic power generating facility is severely changed, and the area of the water surface is considerably wider than the installation area. In addition, And this also caused a problem of lowering the power generation efficiency.

In the case of Patent Document 2, movement in the direction of gravity from a certain position may be possible in accordance with the water level fluctuation in a stationary state in which the wind action is small or the action of the wind is small to such an extent that the wind speed is small and the wind direction can not be measured, The solar module 2, which can not be installed when the wind does not act on the water such as a lake, a reservoir, a dam, or a shared water surface, can not be installed so as to protrude upward, It is possible to easily change the position even in the case of a small wind, and in some cases, in Fig. 13, it causes sweeping movement of distance between the tension holding weight 6 and the length adjusting weight 7 There is a problem that it is necessary to have a larger area than the actual water surface area.

In addition, in the case of a water-immobilized or rotary solar power generation system including
