Description

Technical Field

[0001] The utility model relates to the field of solar panels, and in particular to a solar panel used in a photovoltaic power station for complementary fishing and light. Background Art

[0002] Fishery-solar complementarity refers to the process of combining fishery farming with photovoltaic power generation, in which solar panel arrays are installed above fish ponds or other water surfaces, which can simultaneously realize the two functions of water photovoltaic power generation and underwater farming. The solar panel array installed above the water surface can effectively block the water's absorption of solar radiation and reduce the water temperature, which is not only beneficial to aquaculture, but also helps to improve the power generation efficiency of solar panels.

[0003] Existing patent application number: CN201721347263.5 A solar panel for a fish-light complementary photovoltaic power station, including a solar panel main body, a plurality of light shields are arranged on one side of the solar panel main body, and the light shields are integrated with the solar panel main body. The utility model utilizes the setting of heat dissipation holes and adsorption layers to facilitate the low-temperature airflow contained in water to enter the solar panel main body. After the low-temperature airflow enters the solar panel main body, the heat emitted by each part of the solar panel main body is dissipated, and the adsorption layer absorbs the water vapor contained in the low-temperature gas.

[0004] The above patent records a solar panel used for fish-light complementarity. In actual application, since the solar panel is arranged directly above the fish pond, the water vapor generated by evaporation from the water surface of the fish pond will condense into water droplets on its surface when it encounters the solar panel during the rising process. These water droplets often stay on the back panel of the solar panel for a long time, thereby causing great pressure on the waterproof structure of the solar panel. The moisture-proof function of the solar panel can be further improved to better adapt to the surrounding environment of the fish pond. Utility Model Content

[0022] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0023] See also Figure 1 The utility model provides a solar panel for a fish-photovoltaic complementary photovoltaic power station, comprising a photovoltaic panel 1, a cable 2 and a moisture-proof device 3. The side of the photovoltaic panel 1 is connected to the cable 2, and the bottom of the photovoltaic panel 1 is provided with the moisture-proof device 3.

[0024] See also Figure 2-5 The moisture-proof device 3 in the utility model includes a moisture-proof cover 31, a connecting frame 32, a leakage groove 33, a one-way liquid guide film 34 and a protrusion 35. The moisture-proof cover 31 is arranged below the photovoltaic panel 1. The left and right ends of the top surface of the moisture-proof cover 31 are bolted with the connecting frame 32, and the top of the connecting frame 32 is bolted and fixed to the photovoltaic panel 1. The moisture-proof cover 31 is mounted to the bottom of the photovoltaic panel 1 through the connecting frame 32. The moisture-proof cover 31 plays a shielding role to prevent the water vapor evaporated from the fish pond below from directly reaching the bottom of the photovoltaic panel 1 for condensation. The upper and lower parts of the moisture-proof cover 31 are penetrated by the leakage groove 33. The leakage groove 33 plays the role of discharging the liquid accumulated on the top of the moisture-proof cover 31. The inner side of the leakage groove 33 is provided with a one-way liquid guide film 34. The liquid can only pass through the one-way liquid guide film 34 from top to bottom to prevent water vapor from passing through the moisture-proof cover 31 from the leakage groove 33. The bottom end surface of the moisture-proof cover 31 is integrally provided with a protrusion 35.

[0025] It is further explained that the cross-sectional area of ​​the moisture-proof cover 31 is not less than the cross-sectional area of ​​the photovoltaic panel 1, and the moisture-proof cover 31 is arranged directly below the photovoltaic panel 1, so that the moisture-proof cover 31 can provide good shielding for the photovoltaic panel 1 and prevent the water vapor evaporated from the fish pond below from directly reaching the bottom of the photovoltaic panel 1 and condensing.

[0026] To further illustrate, the one-way liquid guide membrane 34 is laid on the inner side of the connecting sleeve 341, the connecting sleeve 341 is buckled onto the inner side of the leakage groove 33 from top to bottom, and the connecting sleeve 341 is connected and fixed to the moisture-proof cover 31 with screws. When the one-way liquid guide membrane 34 is damaged, it can be replaced by removing the connecting sleeve 341, thereby reducing the replacement cost.

[0027] To further illustrate, the raised portion 35 is spherical, there are no less than two rows of raised portions 35, and the raised portions 35 are distributed side by side on the bottom surface of the moisture-proof cover 31. The raised portions 35 can play a role in gathering droplets. The droplets roll along the surface of the raised portions 35 to the lowest point and gather into water droplets and then drip downward, so that the droplets can quickly return to the fish pond.

[0028] Further explanation: the bottom surface of the moisture-proof cover 31 and the raised portion 35 are coated with a waterproof coating 36, which can reduce the friction between the droplets and the moisture-proof cover 31 and the raised portion 35, making it easier for the droplets to drip downward and return to the fish pond, thereby reducing the adhesion time of the droplets.

[0029] To further explain, a shield 37 is integrally provided on the top surface of the moisture-proof cover 31 , and the shield 37 covers the drain groove 33 , so that the shield 37 intercepts water vapor and prevents the water vapor from passing through the moisture-proof cover 31 from the inside of the drain groove 33 .

[0030] Further explanation: a hinge portion 321 is provided at the lower half of the connecting frame 32, and the connecting frame 32 has a flipping angle of not less than 90 degrees with the hinge portion 321 as a turning point, so that the connecting frame 32 can be flipped downward along the hinge portion 321 and placed horizontally on the top of the moisture-proof cover 31 to reduce the volume of the moisture-proof device 3 and facilitate transportation and storage.

[0031] Here’s how it works:

[0032] First, before use, the connection frame 32 is first flipped to a vertical direction along the hinge portion 321 , and then the top of the connection frame 32 is locked and fixed to the photovoltaic panel 1 with bolts, thereby completing the assembly of the moisture-proof device 3 and the photovoltaic panel 1 .

[0033] Second, when in use, the photovoltaic panel 1 is set up above the fish pond to block the water surface from absorbing solar radiation, thereby reducing the water temperature, which is beneficial to aquaculture. The photovoltaic panel 1 itself can also generate electricity through the photovoltaic effect and transmit electricity to the power grid system through the cable 2, thereby reducing the electricity cost expenditure of aquaculture.

[0034] Third, in the actual application process, since the photovoltaic panel 1 is erected above the fish pond, when the water vapor evaporated from the fish pond rises and encounters the photovoltaic panel 1, it is easy to condense into water droplets on its surface. The long-term retention of water droplets will cause great pressure on the waterproof structure of the photovoltaic panel 1. By installing a moisture-proof cover 31 below the photovoltaic panel 1, the moisture-proof cover 31 can provide a good shielding effect for the photovoltaic panel 1, preventing the water vapor evaporated from the fish pond below from directly reaching the bottom of the photovoltaic panel 1 for condensation. The water vapor will condense on the surface of the moisture-proof cover 31. By providing a spherical crown-shaped protrusion 35 on the bottom end surface of the moisture-proof cover 31, the protrusion 35 can play a role in gathering droplets. The droplets roll along the surface of the protrusion 35 to the lowest point and gather into water droplets and then drip downward, so that the droplets can quickly return to the fish pond and are not easy to stay on the surface of the moisture-proof cover 31 to cause moisture. By providing a waterproof coating 36, the waterproof coating 36 can reduce the friction between the droplets and the moisture-proof cover 31 and the protrusion 35, so that the droplets are more likely to drip downward and return to the fish pond, reducing the attachment time of the droplets.

[0035] Fourthly, a leakage groove 33 is provided on the top surface of the moisture-proof cover 31, and the leakage groove 33 serves to discharge the accumulated liquid, thereby preventing the accumulated liquid from being retained on the top of the moisture-proof cover 31 and causing moisture. In addition, a connecting sleeve 341 is fastened on the inner side of the leakage groove 33, and a one-way liquid guiding membrane 34 is laid on the inner side of the connecting sleeve 341. Liquid can only pass through the one-way liquid guiding membrane 34 from top to bottom, thereby preventing water vapor from passing through the moisture-proof cover 31 from the leakage groove 33 and affecting the photovoltaic panel 1, and a shield 37 is provided above the leakage groove 33, and the shield 37 serves to intercept water vapor, thereby preventing water vapor from passing through the moisture-proof cover 31 from the inner side of the leakage groove 33, thereby providing a good moisture-proof effect for the photovoltaic panel 1.

[0036] Fifth, by setting a hinge part 321 in the lower half of the connecting frame 32, when the moisture-proof device 3 is not assembled with the photovoltaic panel 1, the connecting frame 32 can be flipped downward along the hinge part 321 and placed horizontally on the top of the moisture-proof cover 31 to reduce the volume of the moisture-proof device 3 and facilitate transportation and storage.

[0037] The utility model provides a solar panel for a photovoltaic power station complementary to fishery and photovoltaic. A moisture-proof device 3 is arranged at the bottom of the photovoltaic panel 1. A moisture-proof cover 31 is installed under the photovoltaic panel 1. The moisture-proof cover 31 can provide a good shielding effect for the photovoltaic panel 1 to prevent the water vapor evaporated from the fish pond below from directly reaching the bottom of the photovoltaic panel 1 for condensation. A spherical crown-shaped protrusion 35 is arranged on the bottom end surface of the moisture-proof cover 31. The protrusion 35 can play a role in gathering droplets. The droplets roll along the surface of the protrusion 35 to the lowest point and gather into water droplets and then drip downward, so that the droplets can quickly return to the fish pond and are not easy to stay on the surface of the moisture-proof cover 31 to cause moisture.
