Description

A power generation device for ships using solar tracking and a ship equipped with the power generation device {POWER GENERATING APPARATUS USING SOLAR TRACKING FOR VESSEL AND VESSEL INCLUDING THE SAME}

The present invention relates to a power generating device for a ship using solar tracking and a ship having the power generating device, and more particularly, by rotating a photovoltaic power board according to the position of the sun and the direction of the wind, to increase light collection and power generation efficiency, and lift power It relates to a power generation device for a ship using solar tracking, which can offset the weight of a solar power board installed on a ship by generating excessive thrust, and further increase propulsion efficiency, and a ship equipped with the power generation device.

In general, energy sources such as fossil fuels have limitations such as price increase and resource depletion because they continuously require high technology and capital to make and use them. In addition, nuclear power, which is considered the lowest cost of power generation, guarantees high technology and safety, so the need for eco-friendly and safe new and renewable energy is increasing.

Among them, solar power generation can be used continuously as an infinite resource, can reduce carbon dioxide, and can break away from dependence on fossil fuels. In addition, it is in the spotlight because it is very safe, easy to maintain, and costs little to maintain.

Such a photovoltaic power generation system, as is already known, is a system that generates electricity by a solar cell that generates electricity by the photoelectric effect when it receives sunlight, and elements that store and supply electrical energy. A light collecting plate, a capacitor and a power converter.

A solar panel in which a large number of solar cells are arranged in a module form has the best efficiency when it is at an angle of 90 degrees to the sun's rays. appears severely.

Therefore, in the case of a fixed solar panel, there is a problem in that economic efficiency is lowered because the maximum output is not obtained except for a specific time or a specific season.

In order to solve the above-mentioned problems, a technology for adjusting the angle of a solar panel has been developed.

Conventionally, as a method for adjusting the angle of a solar panel, a manual solar panel angle adjusting device has been developed and has been presented as Korean Patent Registration No. 10-0734217.

This is by seating the support for both rotation shafts on the semi-circular support formed on the cradle, matching the semi-circular cover with the support portion, and then assembling to form a rim that restrains the support for both rotation shafts in the shape of a cylindrical pipe, and the combination of the rotation shaft In order to fix the support after rotating it at a certain angle, the angle fixing piece was inserted and fixed into the angle fixing piece hole formed on the side surface of the cover or the support part.

However, in the manual solar panel angle adjusting device having such a configuration, there is a problem that the user has to manually adjust the angle of the solar panel, and when a strong wind blows in the process of adjusting the angle, the load of the solar panel can be supported. Since the angle control module cannot be worn or damaged, a problem occurs.

In addition, since the angle control module simply supports the load of the solar panel even after installation, durability is weakened.

And, in the solar panel angle adjusting device as presented in Korean Patent Registration No. 10-1192686, a horizontal support installed on the vertical support in the horizontal direction from the rear surface of the solar panel, and both sides of the horizontal support so that the solar panel is rotatable Including side supports respectively installed at the ends, on the side where the horizontal support is installed in the side support, angle adjustment holes through which at least two or more are formed to adjust the angle of the solar panel according to the altitude of the sun, A fixing piece installed on the side support is formed on the horizontal support to extend the side end surface of the horizontal support, and the angle adjustment hole corresponds to the fixing piece so that the horizontal support and the side support are coupled by a fastening member. It was configured to include a fixing hole that is formed through the size to be.

However, the solar panel angle adjusting device having such a configuration also has a problem in that the user has to manually adjust the angle of the solar panel according to the position of the sun that changes according to seasons and time.

In particular, in the case of the conventional solar panel angle adjusting device, only the angle can be adjusted in a predetermined direction (for example, east and west). And since the angle cannot be freely adjusted in the Z-axis direction, even if the angle adjustment function for the solar panel is provided, there is a problem in that the collecting efficiency of sunlight cannot be maximized.

On the other hand, since large ships use a large amount of fossil fuels as energy, they are a major source of carbon dioxide emission. In order to prevent consumption of a large amount of fossil fuels by such large ships, there are large wind-powered ships.

This large wind-powered ship, by installing a plurality of huge sails on the deck, and controlling each sail through a control unit, so as to obtain propulsion. In addition, since this sail is vertically expandable, the sail is extended in order to use the wind power to the maximum during propulsion, and the size of the sail is shortened in order to prevent the influence of the wind force as much as possible during non-propulsion. it is composed to

On the other hand, fossil fuels used to operate ships also have problems such as greenhouse gas emissions and increased operating costs due to crude oil prices. have.

As an example, according to British Patent No. 2234723 publication, a small ship using solar energy has been disclosed. This small ship has a photovoltaic panel mounted on a plurality of sails in a frame installed on the hull.

Accordingly, during propulsion, the sail is extended in order to maximize the use of the wind power, and during non-propulsion, etc., the sail can be folded horizontally in order to prevent the influence of the wind force as much as possible.

However, the above-mentioned small ship can fold the sail in a horizontal state during non-propulsion, etc., but since the sail is merely folded from a vertical state to a horizontal state, the solar power panel mounted on the sail is exposed to rain and wind as it is.

In addition, since the solar panel is fixed only in the direction determined by the sail, it is impossible to adjust the angle freely by automatically tracking the irradiation angle of sunlight, so there is a problem that the light collecting efficiency is very low.

Recently, research on installing a photovoltaic panel on the upper deck of a ship's hull is being conducted, but in this case, the weight of the entire ship is greatly increased by the weight of the photovoltaic panel. In addition, when the solar power generation panel is fixedly installed in only one direction, there is a disadvantage in that light collection and power generation efficiency are lowered.
