Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of photovoltaic power generation, in particular to a water surface floating type photovoltaic power generation equipment. BACKGROUND

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect of the semiconductor interface, mainly composed of solar panels (components), controllers and inverters, and the main components are composed of electronic components. After the solar cells are connected in series and encapsulated for protection, a large area of solar cell components can be formed, and then combined with power controllers and other components to form a photovoltaic power generation device.

[0003] Compared with traditional thermal power generation and wind power generation, photovoltaic power generation saves energy and does not affect the environment. At the same time, the manufacturing cost of photovoltaic power generation equipment is lower than that of wind power generation equipment, and it has been widely used in recent years. The water surface floating type photovoltaic power generation equipment effectively utilizes the vast space of the water surface. When the photovoltaic power generation equipment receives light energy and converts it into electrical energy, it can be cooled due to its close distance to the water surface, avoiding the influence of high temperature on the conversion efficiency of light energy.

[0004] However, the existing water surface floating type photovoltaic power generation equipment may cause local damage to the aluminum frame surface oxide film of the photovoltaic panel during normal use due to the close distance between the photovoltaic panel and the water surface. The erosion of the surge or flood may cause the entire aluminum frame to be eroded, which cannot support the weight of the component, and the water vapor brought by the surge may penetrate from the edge of the photovoltaic panel, causing hydrolysis and corrosion of the internal materials, resulting in power attenuation of the battery component, and affecting its power generation performance and service life.

[0053] Then, the two first connecting seats 503 at the bottom of the photovoltaic panel body 501 are fixedly installed with the top plate 202 in the second floating body 2 by using bolts, the two extension plates 507 at the bottom of the photovoltaic panel body 501 are installed with the extension plate 19, then the first screw pipe 505 is rotated according to the light direction of the place, the photovoltaic panel body 501 is lifted upward at one end through the first screw pipe 505, the inclination angle of the photovoltaic panel body 501 can receive and convert sunlight to the maximum extent, and if the size of the photovoltaic panel assembly 5 and the distance between the two second floating bodies 2 are not matched, the angle of the first screw rod 506 and the extension plate 507 can be adjusted, so that the included angle between the photovoltaic panel body 501 and the second floating body 2 is less than 90°, and the photovoltaic panel body 501 is stably supported.

[0054] After the photovoltaic panel assembly 5 is installed stably, the length of the pull rope 14 and the height of the cleaning assembly 8 can be adjusted. When adjusting, first manually start the switch of the air pump 9 by the staff, the air pump 9 fills the air into the second floating body 2 around through the inflation pipe one 10, the rectangular shell 201 gradually fills with gas, and the sealed cloth cover 205, the support limiting rod 203 and the top plate 202 are lifted up, when the photovoltaic panel body 501 is moved to the end of the top plate 202 and the entire photovoltaic panel body 501 is kept horizontal with the water surface, the staff manually starts the control valve 13, the air pump 9 stops working, and the gas in the sealed cloth cover 205 slowly overflows through the inflation pipe one 10 and the air pump 9. At this time, the staff can manually stabilize the third screw pipe 806, and rotate the third screw rod 805, so that the middle and low ends of the cleaning brush 807 can be in contact with the upper surface of the photovoltaic panel body 501. Then, the metal base plate is used to be clamped at the connection between the third screw rod 805 and the threaded part 804, to stabilize the position of the cleaning brush 807. After the height of the four cleaning brushes 807 is adjusted, the staff needs to quickly pass one end of the pull rope 14 through the hole at one end of the limiting plate 21, and tie it at one end of the photovoltaic panel body 501. At the same time, the pull rope 14 is knotted, so that the length of the remaining pull rope 14 can effectively pull the control valve 13 switch. Due to the influence of the weight of the photovoltaic panel body 501 and the like, the gas in the sealed cloth cover 205 slowly discharges, the top plate 202 returns to the rectangular shell 201, and it is ensured that the photovoltaic panel assembly 5 can receive sunlight;

[0055] In the normal use of photovoltaic panel assembly 5, air pump 9 is regularly started to fill the second floating body 2 with air, so that the photovoltaic panel body 501 remains parallel to the water surface, and the cleaning assembly 8 is started to scrape the surface of the photovoltaic panel body 501, so that the dust on the surface of the photovoltaic panel body 501 is cleaned, and the dried bird droppings can also be rubbed and cleaned. When it rains later, the rain sensor at the photovoltaic panel assembly 5 receives the rain signal, and controls the air pump 9 to start again, so that the cleaning assembly 8 cleans the surface of the photovoltaic panel body 501. The vortex fan 1502 in the connecting cylinder 12 is impacted by the rotating air flow, which can drive the rotating shaft 1501 to rotate, and in turn drive the second gear 1503 to rotate. The second gear 1503 meshes with the first gear 803, which can drive the reciprocating screw 802 to rotate. Under the drive of the reciprocating screw 802, the threaded part 804, the third screw 805, the third screw pipe 806 and the cleaning brush 807 can move out from between the two blocking strips 1802, and the cleaning brush 807 which is not blocked by the blocking strip 1802 expands and rotates to the surface of the photovoltaic panel body 501 under the support of the spring 808, and brushes the surface of the photovoltaic panel body 501. The threaded part 804 moves along the reciprocating thread, and the air pump 9 fills the inflation pipe 11 with air for a certain time, so that the distance moved by the cleaning brush 807 is certain. When the cleaning of the surface of the photovoltaic panel body 501 is completed, the two cleaning brushes 807 move between the two blocking strips 1802. When the wind speed sensor installed on the photovoltaic panel body 501 detects that the wind speed on the water surface reaches a certain value, the wind speed sensor can also control the air pump 9 to start, so that the photovoltaic panel body 501 remains parallel to the water surface, thereby reducing the wind resistance of the photovoltaic panel body 501. At the same time, after lifting the photovoltaic panel body 501, it also avoids the surge caused by strong wind from wetting the photovoltaic panel body 501.
