Description

Technical Field

[0001] The present invention relates to the technical field of offshore photovoltaic technology, and specifically relates to an offshore floating photovoltaic support. Background Art

[0002] Photovoltaic, that is, a photovoltaic power generation system, is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. The energy of the photovoltaic power generation system comes from the inexhaustible and renewable solar energy, which is a clean, safe and renewable energy source. The photovoltaic power generation process does not pollute the environment or damage the ecology. The photovoltaic power generation system is divided into an independent photovoltaic system and a grid-connected photovoltaic system. The photovoltaic power generation system is composed of equipment such as a solar cell array, a battery pack, a charge and discharge controller, an inverter, an AC distribution cabinet, and a solar tracking control system.

[0003] The patent with the publication number CN117220577B discloses an offshore floating photovoltaic support, which includes two anchoring mechanisms. A plurality of floating mechanisms are symmetrically arranged between the two anchoring mechanisms, and a heat dissipation mechanism is fixedly arranged on the floating mechanism; the floating mechanism includes a floating box. Two hinged columns that are rotatably connected to each other are symmetrically and fixedly connected between adjacent two floating boxes. One side of the floating box is slidably sleeved with a splicing box one, and the other side of the floating box is slidably sleeved with a splicing box two. The top of the floating box is fixedly connected with a storage shell; through the two arc-shaped plates on the splicing box two can be in contact and slide with the arc-shaped grooves on the splicing box one, so that the two arc-shaped plates can be pushed to close, thereby driving the two engaging sleeve rods and the connecting rod to be engaged and sleeved, so that two rows of floating boxes can be combined together. When the two rows of floating boxes continue to approach, they can push the splicing box one and the splicing box two to slide into the floating box respectively, so that one end of the connecting rope can be driven by the U-shaped column, and the other end can drive the lifting column to slide down in the limit sleeve, and then drive the rotating rods at both ends to rotate through the connecting seat. When the rotating rods abut against the top of the storage shell, the rotating rods can rotate, so that the two photovoltaic panels can rotate relatively until the two photovoltaic panels can rotate and close and be stored in the storage shell to prevent the photovoltaic from being damaged by the impact of sea waves.

[0004] In the above solution, the relative rotation of the two photovoltaic panels needs to be started again, and it is necessary to judge whether there are wind and waves and the size of the wind and waves in time and then start; when the sea wind is strong, sea waves will be generated, and strong sea winds often occur at sea. Rotating the two photovoltaic panels to close and storing them in the storage shell will cut off the reception and conversion of sunlight by the photovoltaic panels and reduce their working efficiency. Therefore, there is an urgent need for an offshore floating photovoltaic support to solve the above existing problems. Summary of the Invention

[0031] The working principle of the present invention is as follows: The first step: when there are wind and waves at sea, through the recognition and control of the power mechanism 4, the first protective plate 109 and the second protective plate 112 are simultaneously flipped up to the opposite side relative to each other and are respectively embedded in the first placement groove 107 and the second placement groove 108 again, so that the first protective curtain 110 and the second protective curtain 113 are pulled up into a hood-shaped double-layer sleeve on the outside of the photovoltaic panel. Through the light-transmitting setting of the first protective curtain 110 and the second protective curtain 113, when there are sunlight and wind and waves at sea at the same time, it can also ensure that the photovoltaic panel can work, thereby extending the working time of light energy conversion.

[0032] Step 2: When there are winds and waves at sea, the seawater can be introduced into the upper end of the power compartment 401 through the receiving tube 402 and accumulated on the upper side of the inner ring 403 through the surging of the waves. The billiard ball 413 can also be driven to roll back and forth inside the cross tube 411. When the billiard ball 413 touches the first sensing switch 410, the waterproof plate 405 is controlled to open through the connection 407 and the rotator 406, so that the accumulated seawater falls through the waterproof plate 405 and hits the water plate 417 on one side, thereby driving the rotating rod 416 to flip at an angle of about ninety degrees. Through the connection between the rotating rod 416 and the first connecting shaft 111 and the second connecting shaft 114, the opening of the protection component is automatically controlled by wind and waves, thereby improving the timeliness of protection.

[0033] Step 3: When there are winds and waves at sea, the connecting post 505 will also fall off from the arc groove on the upper side of the connecting block 504 and roll to the inner side of the first arc frame 501, and the air pump 507 is controlled by the contact between the connecting post 505 and the second induction switch 506 to inflate the airbag 503, further making the connecting block 504 rise, preventing the connecting post 505 from contacting the arc groove on the upper side of the connecting block 504, and at this time, the electromagnet connected to the control block 409 is disconnected, and at this time, the electromagnet of the block 409 only serves as The spring is used. When the sea waves calm down, as time goes by, the slow deflation valve at the end of the airbag 503 deflates it slowly, the airbag 503 gradually shrinks, the connecting block 504 gradually falls, and the connecting column 505 rolls back into the arc-shaped groove on the upper side of the connecting block 504 to connect the line. The card block 409 is attracted by the electromagnet and retracts into the card slot 408. Under the action of the torsion spring 419, the rotating rod 416 returns to its original position, and the protective component is automatically closed to improve the automation performance.

[0034] Step 4: The seawater introduced by opening the waterproof plate 405 will fall into the lower space of the power compartment 401, and is connected to the scrubbing panel 301 through the suction pipe 304. The electric track 204 is started at a fixed time through the set electric track program, and the scrubbing mechanisms 3 on both sides are controlled to slide along it. At the same time, the suction pipe 304 is controlled by the scrubbing panel 301 to pump seawater into the power compartment 401. The photovoltaic panels are cleaned by the cleaning rollers 303 and seawater, which can timely remove dust attached to the surface of the photovoltaic panels, reduce obstruction to the surface of the photovoltaic panels, and improve the working efficiency of the photovoltaic panels.

[0035] Step 5: By adjusting the setting of the component, starting the motor 208 to rotate can change the direction of the outer frame seat 201, so that the direction of the photovoltaic panel can be adjusted, thereby improving the adjustment ability of the bracket.

[0036] Step 6: Through the design of the outer frame seat 201, after the photovoltaic panel is cleaned by the brushing mechanism 3, the outflowing seawater will automatically flow to the edge under the tilt condition of the outer frame seat 201, and can finally be discharged through the docking of the connecting pipe 203 and the water pipe 104. The seawater can be used for circulating cleaning of the photovoltaic panel, saving the cleaning cost of the photovoltaic panel.
