Embodiment Construction
[0031] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] The invention provides a portable solar sail. The sail surface structure is a rectangular arc wing sail, which is supported by two masts and sail surface supports, and a flexible solar battery panel is arranged on the windward side of the sail surface. The device can make better use of solar and wind energy in the sailing environment of the ship to provide propulsion power, and its structure is simple; the sail surface can be easily adjusted for 360-degree sail angle through the rotating base to make better use of wind energy; The 90-degree pitch angle adjustment of the sail surface is realized by folding the support assembly to better utilize solar energy; the invention can be applied to small ships without hydraulic equipment, and is convenient for manual and convenient operation.

The invention provides a sail by use of solar energy. The sail includes a fixed base, a rotary base, masts, a folding support component, a sail face bracket and a sail face. The rotary base is rotatably installed on the fixed base and can rotate on the fixed base along the horizontal plane. The two masts are parallelly disposed mutually and are fixedly connected mutually through a plurality of rails. The bottom ends of the two masts are hinged with the rotary base and can swing on the rotary base along the upright plane so as to change the angle of pitch. The sail face bracket is fixed to the two masts. The sail face is fixed to the sail face bracket and is widely strutted by the sail face bracket, forming an arc. The sail face is provided with a flexible solar panel. The sail direction angle of the sail face of the invention can be conveniently and quickly adjusted within the range of 360 degrees through the rotary base so that wind energy can be better used. The angle of pitch of the sail face can also be adjusted within the range of 90 degrees through the folding support component so that solar energy can be better used.
Description
technical field [0001] The invention relates to the field of navigation tools, in particular to a portable solar sail. Background technique [0002] In recent years, the pollutants and greenhouse gas emissions caused by ships have attracted increasing attention from humans. With the increasing pressure of energy demand and the shortage of oil resources, saving energy, exploring new ways to use energy and finding new energy have become the focus of research on the world's shipping industry. [0003] Sails have provided propulsion for ships for thousands of years. However, due to the uncertainty of wind resources and the emergence of internal combustion engine power propulsion systems, sails have gradually withdrawn from the shipping industry and can only be seen in sports activities. [0004] On routes where the wind power distribution is suitable, sailing aids can achieve better energy-saving effects. my country's promotion of sailing aids technology can save energy by up t...
