Embodiment Construction

[0032] The present invention will be further described below in conjunction with specific examples and drawings.

[0033] Astronomical background knowledge

[0034] Although the earth orbits the sun, relatively speaking, what is observed on the earth is the sun moving in the sky. In order to accurately describe the movement and position of the sun in the sky, it is assumed that the earth is not moving, taking the earth as the center and taking an arbitrary length as a radius as an imaginary sphere. All stars in the sky, including the sun, are on this sphere around the earth’s axis. Rotating, this imaginary sphere is called the celestial sphere. The two points where the extension of the Earth’s axis and the celestial sphere intersect are called the celestial poles, PN is the north celestial pole, PS is the south celestial pole, and PN-PS is the celestial axis. The circle formed by extending the intersection of the earth’s equatorial plane and the celestial sphere is called the cel...

Abstract

The invention provides a ship-borne adaptive solar cell panel carrying device and an adaption method. The solar altitude angle, solar azimuth angle and ship steering angle are calculated according to the location of a ship and the current date and time and based on the time, latitude and longitude, and ship heading output by a ship-borne GPS and a gyrocompass; and the angle of a solar cell panel is adjusted to make the solar cell panel perpendicular to the sun's rays. The device for implementing the method comprises a main control unit, and three driving rotation units connected with the main control unit. The main control unit is used to calculate the solar altitude angle, solar azimuth angle and ship steering angle and send control commands to the corresponding driving rotation units. By adopting the method and the device of the invention, the solar cell panel can change as the sun and the ship heading change, the solar cell panel can be adjusted automatically to be perpendicular to the sun's rays, a sailing ship can make full use of solar energy, and therefore, the solar energy utilization rate of the ship-borne adaptive solar cell panel is improved.

Description

Technical field [0001] The invention relates to the field of solar cells, in particular to a ship-mounted self-adapting solar battery panel mounting device and an adaptive method. Background technique [0002] With the use of mineral resources such as oil and coal, these one-time non-renewable resources are facing a serious threat of exhaustion, and the burning of mineral resources produces a large amount of greenhouse gases, causing the earth's temperature to rise. In terms of water transportation, with the introduction of international conventions and regulations and the implementation of "MARPOL 73 / 78", the use of traditional energy has been impacted, and the trend of ship emission reduction and low carbon has become increasingly prominent under mandatory requirements. In this context, a lot of research has been done on the application of clean energy for ships within the scope. As a kind of clean energy, solar energy has the advantages of unlimited reserves, no emissions and...
