The working principle of the solar sail deploying and retracting device is as follows:

the cross section of the solar sail 41 is two symmetrical thin wing shapes, and the Bernoulli principle of increasing flow velocity and reducing pressure can know that when the sailing boat is subjected to wind with a certain attack angle in the sailing process, the force applied to the side face of the sailing boat is relatively reduced. That is to say, the larger the gas flow speed, the larger the dynamic pressure, and the smaller the static pressure, and the smaller the flow speed, the smaller the dynamic pressure and the larger the static pressure, the longer the distance the air flow in front of the sail will come together with the air flow behind the sail, so the flow speed is increased, the different flow speeds of the air flow in front of and behind the sail are generated, the pressure difference is also generated, the pressure difference between the front and rear surfaces generates lift force to the sail surface, and the resultant force is the thrust generated by the solar sail 41.

Due to the fact that the stress conditions of the sail surfaces are different under different attack angles, the generated drift force is different, the combined force of the wind sail sections is optimized through optimization of the attack angles of the wind sails, the wind sails can be enabled to receive the maximum propelling force under the best attack angles, and the drift force can offset and reduce the torque of the support 3 and the base 1. The symmetrical sail surfaces have a certain rule in the circumferential range, and the rotation angle of the self-adjusting attack angle device 2 can be reduced according to the rule, so that the flexibility of the whole device is improved.

Because the solar cell panel is light and can be laid along the sail surface, and the stress influence on the sail is small, a certain amount of solar cell panel is embedded on the sail surface, the solar radiation energy is directly or indirectly converted into electric energy through a photoelectric effect or a photochemical effect by absorbing sunlight, and the power generation power of the solar cell panel is influenced by the illumination intensity.

The working process of the invention is as follows: when the ship normally sails, the hydraulic controller 5 controls the hydraulic motor 43 to rotate and enables the solar sail 41 to be kept in a vertical state, the sail assembly 4 is in a sail placing position, wind condition information detected by the detection sensor 6 is transmitted to the self-adjusting attack angle device 2, the self-adjusting attack angle device 2 automatically calculates the deflection attack angle of the sail, signals are transmitted to the hydraulic controller 5, the hydraulic controller 5 controls the distribution of hydraulic oil to enable the self-adjusting attack angle device 2 to control the support 3 to horizontally rotate, the sail assembly 4 is driven to horizontally rotate, and then the optimal attack angle of the sail is adjusted;

when the sail needs to be retracted under special conditions such as severe weather, the hydraulic controller 5 controls hydraulic oil of the motor oil tank 9 to flow to the hydraulic motor 43 through a pipeline, the hydraulic motor 43 drives the sleeve 421 to rotate and drives the positioning block 44 to rotate in the positioning groove 45, the sleeve 421 drives the fixing frame 42 and the solar sail 41 to rotate between 0 and 90 degrees, when the positioning block 44 rotates to the bottom limit of the positioning groove 45, the solar sail 41 is horizontal, and the sail assembly 4 is located at the sail retracting position; the hydraulic control controls the hydraulic telescopic rod 7 to start to contract, the lifting shaft 32 drives the sail assembly 4 to move downwards, and when the lifting shaft 32 moves to the lowest position, the sail assembly 4 enters the rotary seat 31 to realize sail collection; after sailing, according to the incident direction of the solar rays, the hydraulic motor 43 can control the sail assembly 4 to rotate in the rotating space, so that the solar panel can always obtain the strongest illumination, and the maximization of the solar energy utilization rate is realized.
