Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an active solar photovoltaic power generation apparatus capable of adjusting the inclination angle of a solar panel by a wind load,

More particularly, the present invention relates to a solar photovoltaic power generation apparatus, and more particularly, to a solar photovoltaic power generation apparatus capable of minimizing design load and drastically reducing installation cost by being configured to react positively when a solar panel receives a wind load, The present invention relates to an active-type solar photovoltaic power generation apparatus.

Generally, a power generating apparatus generating electricity can be classified into thermal power generation using fossil fuel such as petroleum or coal and solar power, nuclear power, hydroelectric power, tidal power, and wind power generation depending on the energy source used.

Among these power generation devices, a power generation device using nuclear power has an advantage that it can generate electricity at a lower cost than thermal power generation, but installation is limited due to environmental pollution due to radioactivity and harmfulness of human body. Moreover, recently, facility investment has not been smoothly carried out due to the disposal of nuclear waste generated after electricity production.

In the case of thermal power generation, fossil fuels such as coal and petroleum are used. These generation fuels not only discharge substances that pollute the environment when electricity is generated, but also have high fuel costs. Moreover, recently, oil prices have been rising due to a decrease in resource reserves, and as a result, power generation costs have increased, and it is possible to replace them, and development of clean energy that does not generate substances that pollute the environment is required.

In addition, recently, regulations are being implemented to curb the emission of carbon dioxide globally, and it is required to develop a new power generation device that does not emit carbon dioxide.

As such, there is no emission of carbon dioxide, and a power generation device using solar energy is a typical power generation device using clean energy. Recently, the development and installation costs of technology have been reduced, and the spread has been spreading. However, there is a difference in generating capacity depending on the area and the amount of sunshine. However, due to the use of enormous land for installation on a large area, there are many restrictions on the purchase of the land. There was a real difficulty in drawing up the cooperation of the surrounding people in order to install the large-scale power generating facilities.

In addition, as in the prior art, the photovoltaic power generation apparatus installed on the land generates enormous amount of heat in the process of generating electricity by receiving sunlight and enormous amount of wastes are transferred from the land where the solar power generation apparatus is installed, Which causes degradation of performance and causes malfunctions.

Accordingly, an aquarium photovoltaic power generation system in which a solar panel is installed on a water surface of a river, a lake, a reservoir, a dam, and the like is actively proposed in order to secure a wide installation area with abundant sunshine while reducing problems.

BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a reference diagram for explaining an aquarium photovoltaic generation apparatus according to the prior art; FIG.

As shown in the drawing, a conventional photovoltaic solar power generation apparatus includes a solar panel 12 and a frame assembly for supporting the solar panel 12 in a tilted state above the water surface with the aid of a buoyant body.

Unlike the land-based photovoltaic power generation system in which the solar panel is simply supported on the ground in the case of the above-mentioned photovoltaic power generation system, the load from the wave load and the mooring must be considered. In particular, The frame assembly has to be relatively complex and robust. For example, as shown in the drawings, the frame assembly includes a horizontal horizontal frame 11, a longitudinal horizontal frame 12, a first inclined frame 13a, and a second inclined frame 13b, which are attached to the brackets 14, 15a, The horizontal horizontal frame 11 and the vertical horizontal frame 12 do not need to be installed on the land.

In the case of the water photovoltaic device, the amount of material used for the frame assembly increases, and the installation cost is increased so that the cost burden is inevitable. Therefore, a method of minimizing the installation cost of the frame assembly has been contrived.

FIG. 2 is a front perspective view of an aquarium photovoltaic apparatus according to an embodiment of the present invention, FIG. 3 is a rear perspective view of an aquarium photovoltaic apparatus according to an embodiment of the present invention, Side photovoltaic device according to the present invention.

The water photovoltaic device according to the embodiment of the present invention includes a base frame 110, a solar panel 120, a buoyant body 130, a first angle regulating member 140, The first angle regulating member 140 and the second angle regulating member 150 are disposed on the base frame 110 so that the solar panel 120 is optimized for power generation efficiency The inclination angle of the solar panel 120 is lowered when a certain amount of wind load is applied to the solar panel 120 in either the front or rear direction of the solar panel 120, The solar panel 120 is supported so as to be restored to its original inclination angle.

Hereinafter, the construction of an aquarium photovoltaic apparatus according to an embodiment of the present invention will be described in detail with reference to the first angle adjusting member 140 and the second angle adjusting member 150 which are technical essential parts.

The first angle regulating member 140 supports the rear surface side of the solar panel 120 with respect to the base frame 110. When the wind load is applied to the front surface of the solar panel 120, And allows the solar panel 120 to restore its original inclination angle when the wind load applied to the solar panel 120 disappears while allowing the inclination angle to be lowered.

The first angle regulating member 140 supports the base frame 110 and the rear surface of the solar panel 120 in a sloping manner from the rear side of the solar panel 120, A first arm 142, and a first spring 143. The first body 141 of the first angle regulating member 140 is formed as a tubular member hinged to the base frame 110 at its rear end and having a receiving space therein. The first arm 142 is hinged to the rear side of the solar panel 120 and at least a part of the remaining portion is received in the first main body 141 and is guided to be movable forward and backward. The front end of the first arm 142 may be directly hinged to the rear surface of the solar panel 120. However, as shown in the figure, the support frame 120 may be provided on the rear surface of the solar panel 120, It is preferable that the support frame 160 is hinge-coupled to the upper end of the support frame 160. The first spring 143 is a coil-shaped spring that surrounds the outer circumferential surface of the first arm 142 and is supported by the first body 141 to elastically support the first arm 142 . Here, the first spring 143 is not necessarily provided in the form of a coil spring or the outer circumferential surface of the first arm 142, and effectively performs the basic function of elastically supporting the first arm 142 It can be installed in any form as long as it can.

According to the configuration of the first angle regulating member 140, when a predetermined wind load is applied to the entire surface of the solar panel 120, the first arm 142 is retracted from the first main body 141, ) In the direction of lowering the tilt angle about the lower end thereof. As a result, the inclination angle of the solar panel 120 is lowered naturally, and the resistance against the wind is drastically reduced.

The second angle regulating member 150 supports the lower end side of the solar panel 120 with respect to the base frame 110. When the wind load is applied to the rear surface of the solar panel 120, The inclination angle of the solar panel 120 is lowered, and when the wind load applied to the solar panel 120 disappears, the solar panel 120 is restored to its original inclination angle.

The second angle regulating member 150 is installed on the base frame 110 in a forward and rearward direction from the front side of the solar panel 120 and includes a second body 151 and a second arm 152 A second spring 153, and a sliding wheel 154. As shown in Fig. Here, the second main body 151 is installed facing the solar panel 120 in a form that is laid down on the base frame 110 in the forward and backward directions at a position spaced apart from the front side of the solar panel 120, As shown in Fig. The second arm 152 is hinged to the lower end of the solar panel 120 and at least a portion of the remaining portion is received in the second main body 151 to be guided forward and backward. The front end of the second arm 152 may be directly hinged to the lower end of the solar panel 120. However, as shown in the figure, the supporting frame 160 is installed on the rear portion of the solar panel 120, 160 at the lower end thereof. The second spring 153 is a coil-shaped spring that surrounds the outer circumferential surface of the second arm 152 and is supported by the second body 151 to elastically support the second arm 152 . Here, the second spring 153 may be a coil spring or may not be installed so as to surround the outer circumferential surface of the second arm 152 to effectively perform the basic function of elastically supporting the second arm 152 It may be installed in any other form. The sliding wheel 154 is installed at the distal end of the second arm 152 or the lower end of the support frame 160 so that the sliding wheel 154 can smoothly rotate even when the second arm 152 supports the lower end of the solar panel 120. [ Helping them to move forward.

According to the configuration of the second angle regulating member 150, when a wind load is applied to the rear surface of the solar panel 120 while supporting the lower end of the solar panel 120, the lower end of the solar panel 120 is moved forward So that the inclination angle of the solar panel 120 is lowered.

The base frame 110 is coupled to an upper portion of the buoyant body 130 to play a pivotal role in supporting the solar panel 120. Unlike the solar photovoltaic power generation system on the land, the base frame 110 needs to consider not only the mooring conditions due to the wave load, the mooring load, the water depth of the reservoir, and the design load due to the wind load, . However, in the present invention, when a certain amount of wind load is applied to the front surface or the rear surface of the solar panel 120, the inclination angle of the solar panel 120 is reduced by the first angle adjusting member 140 and the second angle adjusting member 150 The resistance against the wind load can be lowered, so that the design load of the base frame 110 can be greatly reduced. This reduces the initial installation cost and increases the lifetime of the device.

The buoyant body 130 is coupled to a lower portion of the base frame 110 to provide buoyancy against the water surface. For this, the buoyant body 130 may be a bushing body 130 of FRP or PE having styrofoam incorporated therein, or a material having such a function, and may be a plurality of small sized bodies as shown in the drawing, .

The operation and operation of the aquarium photovoltaic apparatus according to the embodiment of the present invention thus constructed will be described in detail with reference to FIGS. 5A and 6B and other drawings attached hereto.

5A, when the wind load is not applied or is lower than a predetermined level, the solar panel 120 maintains the initial inclination angle.

However, when a wind load above a certain level is applied to the front surface of the solar panel 120, the inclination angle is lowered while the solar panel 120 rotates around the lower end as shown in FIG. 5B. The first arm 142 of the first angle regulating member 140 is retracted along the first main body 141 against the resilient supporting force of the first spring 143 so that the solar panel 120 is rotated about the lower end thereof It is allowed to rotate in the direction of lowering the inclination angle to lower the inclination angle.

When the wind load applied to the front surface of the solar panel 120 disappears, the first arm 142 is advanced from the first main body 141 by the elastic support force of the first spring 143, 120). As a result, the solar panel 120 rotates in the direction of increasing the inclination angle about the lower end portion to recover the initial inclination angle.

6A, when a wind load of a predetermined level or more is applied to the rear surface of the solar panel 120, the lower end of the solar panel 120 is moved to the front of the solar panel 120 as shown in FIG. The inclination angle is lowered. At this time, the second arm 152 is retracted in the forward direction along the second body 151 against the elastic force of the second spring 153 so that the lower end of the solar panel 120 moves in all directions to lower the inclination angle Allow. Thereafter, when the wind load applied to the rear surface of the solar panel 120 disappears, the first arm 142 advances in the rear direction by the elastic support force of the compressed second spring 153, To the rear. As a result, the inclination angle of the solar panel 120 is restored to the initial inclination angle.
