Multi-branch fixed offshore photovoltaic structure with automatic pitch adjustment

A multi-branch fixed offshore photovoltaic (PV) structure with automatic pitch adjustment, comprising:

• a fixed base;
• a multi-branch integrated tower;
• a sunlight monitoring system;
• a PV device;
• and
• a control and energy storage system;
• wherein the fixed base comprises an upper section, a middle section, and a lower section connected in sequence;
• the lower section is configured for arrangement in a seabed;
• and an end of the upper section away from the middle section is connected to the multi-branch integrated tower through a counter flange;
• the multi-branch integrated tower comprises a main tower body and a plurality of pitch-regulating frames;
• the plurality of pitch-regulating frames is rotatably provided on the main tower body;
• the main tower body comprises a rotating tower portion and a fixed tower portion;
• the rotating tower portion is rotatably provided on an upper portion of the fixed tower portion;
• the fixed tower portion is connected to the upper section of the fixed base through the counter flange;
• the sunlight monitoring system is provided on the rotating tower portion for monitoring a solar orientation and an inclination angle of sunlight relative to the main tower body;
• each of the plurality of pitch-regulating frames is fixedly provided with the PV device;
• the PV device is integrated with a light-sensing device, and the light-sensing device is configured to monitor an illumination area and an illumination intensity on the PV device;
• the control and energy storage system is provided in the fixed tower portion;
• the main tower body, the plurality of pitch-regulating frames, the sunlight monitoring system, and the light-sensing device are all in signal connection with the control and energy storage system;
• the control and energy storage system is in wire or wireless communication with the sunlight monitoring system and the light-sensing device for data transmission;
• and the control and energy storage system is configured to control the rotating tower portion to perform axial rotation relative to the fixed tower portion, and to control each of the plurality of pitch-regulating frames to rotate relative to the main tower body, so as to adjust an angle of the PV device;
• each of the plurality of pitch-regulating frames comprises a bearing motor, a spindle rotary plate, and a main beam;
• and
• the bearing motor is provided with a motor spindle which is connected to the spindle rotary plate;
• the spindle rotary plate is connected to the main beam;
• the PV device is fixedly provided on the main beam;
• the bearing motor is in signal connection with the control and energy storage system;
• and the control and energy storage system is configured to control the motor spindle of the bearing motor to rotate, so as to make the spindle rotary plate drive the main beam to rotate relative to the fixed tower portion, thereby adjusting the angle of the PV device.
