The first movable frame 2 and the second movable frame 3 are in a folded state under a non-working state, and a worker puts the whole device into the sea. By means of the floating frame 1, the whole device floats on the sea surface. The solar panel 4 collects solar energy and converts the solar energy into electric energy under the control of the charge controller to be stored in the storage battery.

When the first movable frame 2 and the second movable frame 3 are close to each other, the sliding groove of the first guide plate 5c1 guides the sliding rod of the second movable frame 3 to move towards the first movable frame 2 and slide upwards at the same time, the second movable frame 3 is lifted above the first movable frame 2 by matching with the butting of the inclined surfaces of the first movable frame 2 and the second movable frame 3, the bottom of the second movable frame 3 is attached to the top end of the first movable frame 2 to slide, and at the moment, the sliding rod of the second movable frame 3 rises to the upper part in the sliding groove of the second guide plate 5c 2. The first guide plate 5c1 and the second guide plate 5c2 cooperate with each other to define a movement locus of the second movable frame 3.
As shown in fig. 3, the light condensing mechanism 6 includes a condensing lens 6a and a rotation driving assembly 6b;
a pair of condensing lenses 6a, each having a pair of rotating shafts rotatably connected to the floating frame 1 at both ends thereof, disposed above the first movable frame 2 and the second movable frame 3, for condensing sunlight toward the solar cell panels 4 on the first movable frame 2 and the second movable frame 3; and the rotary driving assembly 6b is arranged on the floating frame 1, and the output end of the rotary driving assembly is fixedly connected with the rotating shafts on two sides of the condensing lens 6a and used for driving the condensing lens 6a to rotate around the rotating shafts so as to adjust the angle.
The rotary drive assembly 6b is electrically connected to the controller. The condensing lens 6a can effectively improve the condensing efficiency of the solar cell panel 4. The controller adjusts the angle of the condensing lens 6a by matching the rotation driving component 6b with the sun position, so that the sunlight collecting efficiency of the solar cell panel 4 is improved. The rotary drive unit 6b may be a lens such as a generally convex lens or a fresnel lens having higher efficiency.
As shown in fig. 9, the rotary driving assembly 6b includes a driven gear 6b1, a rack 6b2 and a linear driver 6b3; the driven gears 6b1 are provided with a pair of gears, are respectively fixedly connected with the rotating shafts of the condensing lenses 6a and are used for independently driving the single condensing lens 6a to rotate;
the rack 6b2 is meshed with the driven gear 6b1, the moving direction of the rack is perpendicular to the floating frame 1, and the rack is used for driving the driven gear 6b1 to rotate;
and the linear drivers 6b3 are arranged on two sides of the floating frame 1, and output shafts are fixedly connected with the racks 6b2 and used for driving the racks 6b2 to move in the vertical direction.
The linear actuator 6b3 is an electric push rod electrically connected to the controller and having a function of preventing circumferential deflection. The controller sends a signal to the linear driver 6b3, and the linear driver 6b3 receives the signal and drives the rack 6b2 to move in the vertical direction, so that the condensing lens 6a is driven to rotate on the floating frame 1. When the first movable frame 2 and the second movable frame 3 are folded, only the solar cell panel 4 on the second movable frame 3 can collect sunlight, and the working directions of the two condensing lenses 6a are concentrated towards the upper end of the second movable frame 3. When first adjustable shelf 2 and second adjustable shelf 3 expand, two condensing lens 6a carry out spotlight to solar cell panel 4 on first adjustable shelf 2 and the second adjustable shelf 3 respectively. When the tooth surfaces are arranged on both sides of the rack 6b2, the angles of the pair of condensing lenses 6a can be adjusted at the same time, but the angles cannot be adjusted independently, so that the actual use situation is not facilitated. The independent control adopted by the scheme is more beneficial to improving the light condensation effect.
As shown in fig. 9, a dovetail guide bar 6b4 slidably connected to the floating frame 1 in the vertical direction is provided on one side of the rack bar 6b2 close to the floating frame 1.
The dovetail guide strip 6b4 can further prevent the rack 6b2 from circumferentially deflecting on the output shaft of the linear driver 6b3, so that the linear driver 6b3 can be replaced by a lower-cost driver without axial self-locking function. Dovetail guide strip 6b4 can also prevent rack 6b2 from taking place the sideslip, improves the stability of drive structure greatly.

The anchoring support 7a is of a structure similar to an inverted pyramid and is made of a material with higher density so as to improve the stability of the device on the sea. When meeting with large wind and waves, in order to prevent the device from turning over, the controller sends a signal to the second rotary driver 7c, the second rotary driver 7c receives the signal and then drives the impeller 7b to rotate, and the second rotary driver 7c generates a force for dragging the device downwards, so that the draught of the device is increased, and the stability of the device is further improved.

And step two, the solar panel 4 collects solar energy and converts the solar energy into electric energy under the control of the charging controller to store the electric energy into the storage battery. When the retraction mechanism 5, the light gathering mechanism 6 and the anchoring mechanism 7 need power consumption, the controller switches the storage battery into a discharge mode through the charging controller matched with the solar panel 4 for power supply.
And step three, the controller sends a signal to the light condensing mechanism 6, and the light condensing mechanism 6 adjusts the angle after receiving the signal to find the optimal light condensing angle, so that the solar energy collecting efficiency of the solar cell panel 4 is improved.
And step four, when the device needs to be unfolded to further improve the sunlight irradiation area, the controller sends a signal to the retraction mechanism 5, the retraction mechanism 5 drives the first movable frame 2 and the second movable frame 3 to be reversely separated and flattened after receiving the signal, the two solar panels 4 on the first movable frame 2 and the second movable frame 3 work simultaneously, and the solar energy collection efficiency is doubled.
And step five, the controller sends a signal to the light condensing mechanism 6, and the angle of the light condensing mechanism 6 is adjusted to ensure that light rays are concentrated on the two solar panels 4.
And step six, when the device is positioned on the sea surface, the device is anchored through the self weight of the anchoring mechanism 7, and the capability of resisting the wind waves of the device is improved.
And step seven, when the storm is large, the controller sends a signal to the anchoring mechanism 7, and the anchoring mechanism 7 generates a force sinking to the sea surface after receiving the signal, so that the integral draft of the device is increased, and the resistance effect of the device to the storm is further improved.
And step eight, during the device recovery, the controller sends a signal to the retraction mechanism 5, and the retraction mechanism 5 receives the signal and then folds the first movable frame 2 and the second movable frame 3 for convenient transportation.
