Description

Technical Field

[0001] This invention belongs to the field of hydrogen production technology, specifically a voltage-stabilized power supply device for hydrogen production by water electrolysis adapted to wind and solar power. Background Technology

[0002] Hydrogen is a clean and efficient energy carrier that can be produced through various methods, including fossil fuel combustion, water electrolysis, and biomass fermentation. Electrolysis for hydrogen production is a technology that separates water into hydrogen and oxygen by electrolyzing it. This process requires an electric current to drive the reaction and is primarily used in chemical production environments that require large quantities of hydrogen.

[0003] However, the existing device does not have photovoltaic modules installed to power the electrolysis components. Under sufficient sunlight, it cannot convert solar energy into electricity to power the device, resulting in higher electricity costs and reduced energy self-sufficiency. Summary of the Invention

[0004] The purpose of this invention is to address the problem that the aforementioned device does not have a photovoltaic module installed to power the electrolysis unit, and therefore cannot convert solar energy into electrical energy to power the device under sufficient sunlight, resulting in high electricity costs and reduced energy autonomy. The invention provides a voltage-stabilized power supply device for water electrolysis hydrogen production that is compatible with wind and solar power.

[0005] The technical solution adopted in this invention is as follows: it includes a photovoltaic panel, a photovoltaic bracket is connected and installed on the lower surface of the photovoltaic panel, a photovoltaic cable is fixedly installed on the rear outer surface of the photovoltaic bracket, a charge and discharge controller is fixedly installed on the other end of the photovoltaic cable, a storage battery is fixedly installed on the other end of the charge and discharge controller, a base is fixedly installed on the lower surface of the storage battery, a fixing frame is fixedly installed on the upper surface of the base, and a DC power supply is fixedly installed on the upper surface of the fixing frame.

[0006] By adopting the above technical solution, a photovoltaic bracket is connected and installed on the lower surface of the photovoltaic panel. A photovoltaic cable is fixedly installed on the rear outer surface of the photovoltaic bracket. A charge / discharge controller is fixedly installed at the other end of the photovoltaic cable, and a battery is fixedly installed at the other end of the charge / discharge controller. A base is fixedly installed on the lower surface of the battery, and a mounting bracket is fixedly installed on the upper surface of the base. A DC power supply is fixedly installed on the upper surface of the mounting bracket. The photovoltaic panel converts solar energy into electrical energy, providing clean energy for the electrolysis hydrogen production process. The photovoltaic bracket is fixedly installed outdoors to ensure that the photovoltaic panel converts electricity under sufficient sunlight. The photovoltaic bracket is connected to the photovoltaic panel through an electric rotating shaft, which provides support for the photovoltaic panel and allows adjustment of the angle of the photovoltaic panel on the upper surface of the photovoltaic bracket. The photovoltaic cable is used to transmit the DC power generated by the photovoltaic panel to indoor equipment. The charge / discharge controller controls the charging and discharging process of the DC current generated by the photovoltaic module. To ensure the effective utilization of electrical energy and prevent abnormal situations such as overcharging, over-discharging, and short circuits, the battery stores excess electrical energy when the photovoltaic modules generate more power, and provides power support for a certain period of time when photovoltaic power generation is insufficient. The base is installed indoors as the main installation foundation of the device, used to share and bear the weight of the device itself. The mounting bracket can expand the installation area of ​​the photovoltaic modules, ensuring that the photovoltaic modules can be fixed inside the device and supporting the components mounted on their upper surfaces. The DC power supply is electrically connected to the battery, connecting the DC power generated by the photovoltaic modules with other equipment inside the device that requires DC power. This allows the DC power to be directly used in the water electrolysis process, improving the utilization rate of electrical energy. By installing photovoltaic modules to power the electrolysis modules in this device, solar energy can be converted into electrical energy to supply the device under sufficient sunlight conditions, thereby reducing electricity costs and improving energy self-sufficiency.
