Description

Technical Field

[0001] This utility model relates to the field of photovoltaic energy storage power technology, and in particular to a photovoltaic energy storage power heating device. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. It mainly consists of three parts: solar panels (modules), controllers, and energy storage power sources. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with components such as power controllers, this forms a photovoltaic power generation device. The electrical energy generated by photovoltaic power generation is stored through energy storage devices and then used for heating, heat supply, and other purposes.

[0003] Utility model CN220234606U discloses a photovoltaic energy storage power supply heating device, belonging to the field of photovoltaic energy storage power supply technology. It includes an equipment box and a photovoltaic panel. A mounting base is fixedly connected to the top of the equipment box, and a groove is formed on the top of the mounting base. The photovoltaic panel is placed in the groove. A fixing plate is installed on the outer wall of the equipment box, and an air pump is installed on the fixing plate. Air pipes are fixedly connected to the left and right side walls of the groove, and a flexible hose connects the air pump and the air pipes. A plurality of air holes are evenly spaced on the side walls of the air pipes, with the air holes facing the end face of the photovoltaic panel. This utility model solves the problems in the prior art where photovoltaic panels are easily covered with dust, sand, and other impurities. If not cleaned in time, this can lead to reduced power generation efficiency and increased failure rate of the photovoltaic panel. It is simple and convenient to operate and highly practical.

[0004] The search revealed that the existing technology uses electricity generated by photovoltaic power generation to provide heating. However, the utilization rate of photovoltaic power generation is low, and heating by electricity alone is inefficient. Furthermore, impurities easily adhere to the photovoltaic panels, and blowing air alone cannot completely clean the panels. Therefore, a photovoltaic energy storage power supply heating device is needed to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to provide a photovoltaic energy storage power supply heating device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic energy storage power supply heating device, comprising an energy storage power supply, a photovoltaic panel, and a water storage tank. The photovoltaic panel is installed at an angle on top of the energy storage power supply. The photovoltaic panel and the energy storage power supply are electrically connected via a controller. A heating device is installed inside the water storage tank. The heating device and the energy storage power supply are electrically connected via an inverter. A water supply pipe is installed on one side of the bottom of the water storage tank, and an integrated pipe is connected to one side of the top. Several heat absorption pipes are installed on the bottom of the integrated pipe. The heat absorption pipes are arranged on the back surface of the photovoltaic panel. Several spray pipes are installed on the integrated pipe, and the water outlets of the spray pipes all point towards the top of the sun-facing surface of the photovoltaic panel.

[0007] Preferably, the surface of the water storage tank is provided with an insulation layer, which is a composite layer of rock wool and galvanized iron sheet.

[0008] Preferably, a pressure relief valve is provided on the top of the water storage tank.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the connection between the heating device and the energy storage power supply enables the energy storage power supply to provide electrical energy to the heating device, thereby achieving the effect of heating the water source in the water storage tank. At the same time, the heat generated during the absorption of solar energy by the photovoltaic panel heats the water source inside the heat absorption pipe. Through the connection between the heat absorption pipe, the integrated pipe and the water storage tank, the thermal energy utilization of the photovoltaic panel is realized, and the heating efficiency is improved.

[0015] In this invention, the spray pipe design allows the water tank to be filled with water at night when the water level reaches the integrated pipe.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A photovoltaic energy storage power supply heating device includes an energy storage power supply 1, a photovoltaic panel 2, and a water storage tank 3. The photovoltaic panel 2 is installed at an angle on the top of the energy storage power supply 1. The photovoltaic panel 2 and the energy storage power supply 1 are electrically connected through a controller. A heating device 4 is installed inside the water storage tank 3. The heating device 4 and the energy storage power supply 1 are electrically connected through an inverter. A water supply pipe 5 is installed on one side of the bottom of the water storage tank 3, and an integrated pipe 6 is connected to one side of the top. Several heat absorption pipes 7 are installed on the bottom of the integrated pipe 6. The heat absorption pipes 7 are all arranged on the back side of the photovoltaic panel 2. Several spray pipes 8 are installed on the integrated pipe 6. The water outlet of the spray pipes 8 all points to the top of the sun-facing side of the photovoltaic panel 2.

[0022] During the day, the energy storage power supply 1 provides power to the heating device 4, enabling the heating device 4 to heat the water in the water storage tank 3. At the same time, the heat generated by the photovoltaic panel 2 during the absorption of solar energy heats the water inside the heat absorption pipe 7. Through the connection between the heat absorption pipe 7, the integrated pipe 6, and the water storage tank 3, the heat energy of the photovoltaic panel 2 is utilized, thereby improving the heating efficiency. At night, water is added to the water storage tank 3 through the water supply pipe 5. When the water level reaches the integrated pipe 6, the water fills the heat absorption pipe 7. The excess water flows out from the spray pipe 8 to clean the photovoltaic panel 2, removing the dust adsorbed on the photovoltaic panel 2 during the day, thereby ensuring the efficiency of the photovoltaic panel 2 in receiving solar energy the next day. Furthermore, the water level in the water storage tank 3 can be judged by observing the water flowing out of the spray pipe 8, so as to stop adding water.

[0023] Specifically, in this embodiment, the surface of the water storage tank 3 is provided with an insulation layer, which is a composite layer of rock wool and galvanized iron sheet, to reduce the temperature loss after the water source is heated.

[0024] Specifically, in this embodiment, a pressure relief valve is provided on the top of the water storage tank 3 to provide pressure relief for the water temperature inside the water storage tank 3 when it rises, and to prevent the water storage tank 3 from expanding and being damaged.

[0025] Specifically, in this embodiment, a motor 9 is installed on the water storage tank 3. The motor 9 is electrically connected to the energy storage power supply 1 through an inverter. A stirring rod 10 is installed on the output end of the motor 9. The stirring rod 10 is arranged inside the water storage tank 3. The motor 9 can drive the stirring rod 10 to rotate inside the water storage tank 3, thereby achieving an efficient mixing effect for the water source with temperature difference inside the water storage tank 3.

[0026] Specifically, in this embodiment, several heat-absorbing pipes 7 are connected to the back surface of the photovoltaic panel 2 by clamps to ensure the connection effect between the heat-absorbing pipes 7 and the photovoltaic panel 2, and at the same time help the heat-absorbing pipes 7 absorb the heat of the photovoltaic panel 2.

[0027] Specifically, in this embodiment, the heat-absorbing tube 7 is made of copper. An aluminum foil insulation layer can be added to the back surface of the photovoltaic panel 2 to cover several heat-absorbing tubes 7, thereby improving the heat conduction performance and preventing heat loss after the heat-absorbing tube 7 absorbs heat.

[0028] Specifically, in this embodiment, the spray pipe 8 is a right-angle bend, which allows water to flow out from the spray pipe 8 under a certain pressure, thus preventing water leakage.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto.
