[0037] The present invention provides an integrated photovoltaic power generation and energy storage device: comprising a photovoltaic panel 1; also comprising a photovoltaic assembly; the photovoltaic assembly comprises a photovoltaic bracket 2, an installation cabinet 3, a heat-conducting frame 4, a plurality of heat dissipation fins 5, a battery 6, a water storage tank 7, a water supply pipe 8, a temperature control valve mechanism 9, two branch pipes 10 and a plurality of nozzles 11; the installation cabinet 3 comprises a cabinet body 31, a cabinet door 32 and a handle 33; the temperature control valve mechanism 9 comprises an installation cylinder 91, a connecting cylinder 92, a push rod 93, a first piston 94, a second piston 95 and a spring 96; the photovoltaic assembly further comprises two support rods 12 and two fans 13; the photovoltaic assembly further comprises a water pump 14, a water outlet pipe 15 and a perforated spray pipe 16; the photovoltaic assembly further comprises a photovoltaic controller 17 and an inverter 18; the photovoltaic assembly further comprises a connecting pipe 19, a collecting bucket 20 and a conical filter 21; the above-mentioned scheme solves the problem that the battery 6 of the existing integrated photovoltaic power generation and energy storage device is easily damaged by overheating.

[0038] Furthermore, the photovoltaic panel 1 is fixedly arranged on the photovoltaic bracket 2; the installation cabinet 3 is fixed on the photovoltaic bracket 2; the heat-conducting frame 4 is fixedly arranged in the installation cabinet 3; a plurality of the heat dissipation fins 5 are fixedly arranged on both sides of the heat-conducting frame 4; the battery 6 is arranged in the heat-conducting frame 4; the water tank 7 is fixedly arranged on the photovoltaic bracket 2; the water supply pipe 8 is connected to the water tank 7 and passes through the installation cabinet 3; the temperature control valve mechanism 9 is fixedly arranged on the top of the heat-conducting frame 4 and connected to the water supply pipe 8; the two branch pipes 10 are respectively connected to the temperature control valve mechanism 9 and respectively pass through the installation cabinet 3; and each branch pipe 10 is connected to a plurality of the nozzles 11.

[0039] In this embodiment, the photovoltaic bracket 2 supports the photovoltaic panel 1, and the photovoltaic panel 1 receives sunlight to generate electricity and stores the electrical energy in the battery 6. The installation cabinet 3 is also installed on the photovoltaic bracket 2. The heat-conducting frame 4 is composed of four heat-conducting plates, which form a rectangle to wrap the battery 6. A plurality of heat-dissipating fins 5 are installed on the left and right sides of the heat-conducting frame 4, and the plurality of heat-dissipating fins 5 are all located outside the installation cabinet 3. The temperature control valve mechanism 9 switches according to the temperature change of the heat-conducting frame 4. When the temperature of the battery 6 is higher, the temperature of the heat-conducting frame 4 is also higher, and the temperature control valve mechanism 9 will automatically open, and the water in the water tank 7 can be smoothly supplied to the two branch pipes 10 through the water supply pipe 8, and then supplied to the plurality of nozzles 11, and the plurality of nozzles 11 are all aimed at the heat-dissipating fins 5. When the temperature of the battery 6 drops, the temperature control valve mechanism 9 will also automatically close; when in use, the battery 6 generates heat, and the heat is transferred to the multiple heat dissipation fins 5 through the heat conduction frame 4. The multiple heat dissipation fins 5 exchange heat with the air, thereby realizing the heat dissipation of the battery 6. When the battery 6 is overheated, the temperature of the heat conduction frame 4 also rises, and the temperature control valve mechanism 9 will automatically open, and the water in the water tank 7 will be supplied to the two branch pipes 10 through the water supply pipe 8, and then supplied to the multiple nozzles 11. The multiple nozzles 11 are all aimed at the heat dissipation fins 5 to spray water mist, further improving the heat dissipation effect of the multiple heat dissipation fins 5, so that the temperature of the battery 6 can be quickly and effectively reduced, thereby solving the problem that the battery 6 of the existing integrated photovoltaic power generation and energy storage device is easily overheated and damaged. Spraying water on the heat sink fins 5 can increase the heat exchange area. Spraying water forms a water film on the surface of the heat sink fins 5. This water film increases the surface area of ​​the heat sink fins 5, thereby increasing the heat exchange area, so that more heat can be transferred through water molecules; at the same time, the specific heat capacity of water is large, which means that water can absorb more heat without much temperature increase. When water molecules absorb heat, they evaporate, and this process requires absorbing a large amount of heat, thereby effectively taking away heat from the surface of the heat sink fins 5.

[0040] Furthermore, the cabinet body 31 is fixedly arranged on the photovoltaic support 2 ; the cabinet door 32 is rotatably arranged on one side of the cabinet body 31 ; and the handle 33 is fixedly arranged on the cabinet door 32 .

[0043] In this embodiment, the bottom of the installation cylinder 91 is open, and the installation cylinder 91 below the first piston 94 is filled with preheated and expanded gas, which is in direct contact with the heat-conducting frame 4 and can be helium. The spring 96 gives the second piston 95 an elastic force, and the second piston 95 blocks the connection between the water supply pipe 8 and the connecting cylinder 92, so that water cannot enter the connecting cylinder 92. When the battery 6 is overheated, the temperature of the heat-conducting frame 4 rises sharply, and the gas in the installation cylinder 91 begins to expand and pushes the first piston 94 upward. The first piston 94 pushes the second piston 95 upward through the push rod 93 to expose the connection between the water supply pipe 8 and the connecting cylinder 92. Water enters the connecting cylinder 92 from the water supply pipe 8 to supply the two branch pipes 10. At this time, the spring 96 is compressed; when the temperature of the battery 6 decreases, the gas contracts, and the spring 96 pushes the second piston 95 downward to block the connection between the water supply pipe 8 and the connecting cylinder 92 again.

[0044] Furthermore, the two support rods 12 are respectively fixedly arranged on one side of the cabinet 31 ; the two fans 13 are respectively fixedly arranged on one side of the two support rods 12 .

[0045] In this embodiment, the support rod 12 is used to install the fan 13, and the fan 13 is aimed at the heat dissipation fins 5 to increase air flow and improve the heat dissipation effect. After spraying water, it can also accelerate the evaporation of water and improve the heat dissipation effect.

[0047] In this embodiment, the perforated spray pipe 16 is evenly provided with a plurality of water outlet holes, and the water pump 14 supplies the water in the water storage tank 7 to the perforated spray pipe 16 through the water outlet pipe 15. The perforated spray pipe 16 sprays water from the higher side of the photovoltaic panel 1 to wash away the dust on the photovoltaic panel 1 to avoid affecting the power generation effect.

[0048] Furthermore, the photovoltaic controller 17 is fixedly disposed inside the cabinet 31 , and the photovoltaic controller 17 is electrically connected to the photovoltaic panel 1 and the battery 6 , respectively; the inverter 18 is fixedly disposed inside the cabinet 31 , and is electrically connected to the battery 6 .

[0049] In this embodiment, the photovoltaic controller 17 is used to control the charging and discharging of the battery 6, and the inverter 18 is used to convert the direct current of the battery 6 into alternating current for supplying to the load.

[0050] Furthermore, the connecting pipe 19 is arranged on one side of the water storage tank 7 ; the collecting bucket 20 is arranged on one side of the connecting pipe 19 ; and the conical filter screen 21 is fixedly arranged on the top of the collecting bucket 20 .

[0051] In this embodiment, the collecting hopper 20 is used to collect rainwater, which is then sent to the water storage tank 7 for storage through the connecting pipe 19. In this way, there is no need to add water to the water storage tank 7 regularly. At the same time, the conical filter 21 is arranged on the top of the collecting hopper 20 to prevent impurities from entering the collecting hopper 20 and clogging subsequent pipelines. Impurities falling on the conical filter 21 will also fall automatically under the action of gravity.
