It may be. That is, the opening and closing door 76 may be installed so as to be opened and closed by using a valve by a manual or electric method. In this case, a detailed description of the opening or closing door of the electric method or manual method will be omitted since it is well known in the art.

The pump and the air inlet and outlet are installed so that the inflow or outflow of water from the compartments 71 or the inflow or outflow of air is independently performed for each compartment.

That is, by generating the differential of buoyancy for each compartment, the buoyancy support 70 itself can be inclined to one side to adjust the angle of the solar cell module 10.

In addition, by simultaneously increasing or decreasing the buoyancy of each compartment 71, the entire buoyancy support 70 may be located at a predetermined depth below the surface of the water or float above the surface of the water.

This is to adjust the angle of the solar cell module, such as the control rod 80 to maintain the power generation efficiency of the solar cell module to the maximum, and also the possibility of damage to the solar cell module due to the impact of typhoons or strong winds, etc. In order to facilitate the management of the solar cell module 10 by adjusting the buoyancy of the buoyancy support 70 so that the solar cell module 10 is located under the water surface.

In addition, even when the temperature of the solar cell module itself rises as well as preventing damage from typhoons or strong winds, the buoyancy of the buoyancy support 70 is reduced so that the solar cell module 10 is kept under the water surface. Adjust the temperature to lower the temperature of the solar cell module, when the solar cell module 10 is located under the water surface to generate power when the power generation efficiency of the solar cell module is lowered due to deterioration of water quality of the buoyancy support 70 It raises the buoyancy to expose the solar cell module to the surface.

The configuration of the buoyancy support 70 may be equally applied to the first buoyancy member 40a to the second buoyancy member 40b.

By rising or falling of the buoyancy support 70, the weight 90 will also be raised or lowered as well.

The first buoyancy member 40a or the first buoyancy member 40a and the second buoyancy member 40b constituting the first embodiment of the present invention is composed of a plurality of compartments, each of which has a pump and air When the entrance and the like are provided, and the interior of the buoyancy support 70 constituting the second embodiment of the present invention is composed of a plurality of compartments 71 and a pump 72 and an air inlet 74 in each compartment 71. (Including the air pipe 75 and the opening and closing door 76), the operation of the pump and the air entrance (especially when the above-described opening and closing door of the electric system) is controlled automatically, according to the main surface environment The position of the solar cell module 10 may be adjusted. Hereinafter, only the buoyancy support 70 will be described as an example, but this configuration may be equally applied to the first buoyancy member 40a and the second buoyancy member 40b of the first embodiment.

For this operation, the configuration that can be located on the water surface of the configuration of the floating photovoltaic device according to the present invention (for example, the adjusting rod 80 or the second support wire 35 or the solar cell module of the third embodiment) (10) and the like are provided with a wind speed sensor for measuring the wind speed.

In addition, a pressure sensor for measuring the pressure applied to the solar cell module 10 may be further installed in the solar cell module 10, and an angle sensor for measuring the angle of the solar cell module 10 may be further installed. Can be.

At this time, the floating photovoltaic device according to the present invention includes a control unit for controlling the operation of the pump or the door.

That is, when it is necessary to arrange the entire solar cell module 10 below the water surface, the controller controls the pump 72 so that a predetermined amount of water flows into all the compartments 71 of all the buoyancy supports 70. When the solar cell module 10 rises above the water surface, the pump is operated in reverse so that water inside the compartment flows out.

In addition, when it is necessary to adjust the angle of the solar cell module 10, the control unit is the angle so that the solar cell module can be inclined at a predetermined angle by the buoyancy difference of each compartment 71 constituting the buoyancy support 70. The pump 72 of the compartment is operated.

In this case, the controller opens the opening and closing door 76 when the pump 72 is operated to allow the external water to flow into the compartment or the internal water to the outside, and the pump 72 is not operated. There is a control so that the closing door 76 is closed. Since the opening and closing operation of the opening and closing door 76 for the operation of the pump 72 is applied in the same manner below, the description thereof will be omitted.

The controller may be connected to the wind speed sensor and / or the water pressure sensor and / or the angle sensor, and the wind speed, the water pressure, the angle value measured by the wind speed sensor and / or the water pressure sensor, and / or the angle sensor, and the preset appropriate wind speed value. And a microprocessor for comparing the proper hydraulic pressure value and the proper angle value, respectively.

That is, when the wind speed value measured by the wind speed sensor is larger than the appropriate wind speed value preset in the microprocessor, the controller operates a pump in each compartment inside the buoyancy support 70 to draw external water into each compartment. Inflow to and control so that the buoyancy of the buoyancy support 70 is reduced. When the buoyancy of the buoyancy support 70 is lowered down to the surface of the water, the second support wire 35 and the solar cell module 10 coupled to the second support wire 35 are also lowered below the water surface. .

In this case, when the proper pressure value preset in the microprocessor and the pressure value measured by the pressure sensor are equal to each other, the controller stops the operation of the pump so that the buoyancy of the buoyancy support 70 is no longer reduced.

That is, when it is necessary to be positioned below the surface of the water to protect the solar cell module 10 from typhoons or strong winds, the buoyancy of the buoyancy support 70 is adjusted to reduce the buoyancy of the buoyancy support, so that the solar cell module is below the water surface. Can be controlled so as to be disposed at a proper position (that is, a position having a proper hydraulic pressure).

In addition, after a typhoon or strong wind disappears, or after a predetermined time set by the microprocessor, the control unit operates the pump of each compartment in reverse to allow the water inside each compartment to flow out to the outside and the buoyancy support 70 Restore buoyancy). When the buoyancy of the buoyancy support 70 is restored accordingly, the buoyancy support 70 rises in the water direction, and at the same time, the second support wire 35 and the solar cell module also rise.

In this case, the controller controls the opening / closing operation of the opening / closing door so that air may flow into or out of each compartment or compartment through the air inlet and outlet while the pump 72 is operated.

In addition, when the proper angle value of the solar cell module plane set in advance in the microprocessor and the angle value measured by the angle sensor exceeds a predetermined error range set in the microprocessor, the control unit is an angle value of the solar cell module plane And pumps of each compartment so that a difference in buoyancy of each compartment 71 is generated by operating a pump of some compartments 71 of the buoyancy support 70 so that the proper angle value is within an error range. Activate

At this time, the pump of each compartment is controlled so that the buoyancy support 70 is inclined so that the difference between the proper angle value and the angle value measured by the angle sensor is reduced. That is, by controlling the buoyancy of each compartment of the buoyancy support 70 by controlling one side of the buoyancy support 70 to be lowered below the surface of the water, the proper angle value and the angle value measured by the angle sensor are within the error range. The pumps in each compartment are operated to be present.

In this case, the appropriate angle value is preferably set in advance by date and time in the microprocessor.

The solar cell module may further include a temperature sensor for measuring the temperature of the solar cell module, in this case, the microprocessor is set in advance an appropriate temperature range of the solar cell module.

At this time, if the temperature value measured by the temperature sensor exceeds a predetermined temperature range set in advance in the microprocessor, the controller operates the pump of each compartment of the buoyancy support 70 to reduce the buoyancy of the buoyancy support The solar cell module may be positioned at a position having a constant proper pressure value under the water surface.

At this time, the floating photovoltaic device according to the present invention may further include a communication module.
