Description

Technical Field

[0001] The present invention belongs to the technical field of heat pipe type electrolytic water hydrogen storage, and in particular relates to a heat pipe type electrolytic water multi-stage heating power supply hydrogen storage device and a power supply hydrogen storage method. Background Art

[0002] Electrolysis hydrogen production technology is currently relatively mature. Electrolysis hydrogen production technology converts sunlight into electricity through solar cell arrays and stores it in battery packs to meet users' electricity needs at night or in bad weather. At the same time, when the energy storage battery pack cannot meet the electricity demand, hydrogen energy technology can convert water into hydrogen through water electrolysis reaction and store it.

[0003] A Chinese patent with the announcement number CN115085351B discloses an emergency power supply device that connects photovoltaic energy storage and hydrogen energy in parallel, belonging to the field of power supply technology. The present invention includes a device housing, the exterior of which is provided with at least four electric push rods, the bottom of which is provided with an electronic level, the electronic level and each electric push rod are electrically connected to a control system, a solar panel is provided above the device housing, and the interior of the device housing is provided with an adjustment component, a hydrogen energy component, and a battery. The solar panel generates electricity using the sun, and the hydrogen energy component generates electricity using hydrogen combustion. The adjustment component adjusts the solar panel, and the battery stores the electricity generated by the solar panel and the hydrogen energy component. The electronic level detects the posture of the device housing, and at least four electric push rods adjust the device housing to maintain balance.

[0004] In the current existing technology, during use, the second motor and the first motor are powered to control the horizontal and vertical angles of the light collecting bracket, respectively. These two are controlled by two independent control systems, resulting in the need for two electrical control systems. This not only makes the structure more complex but also increases the cost of equipment development. Therefore, the overall structural circuit planning needs to be optimized. In addition, during the electrolysis hydrogen production process, increasing the electrolytic water temperature can reduce energy dissipation, thereby improving electrolysis efficiency. However, increasing the electrolytic water temperature requires additional heating equipment and energy consumption, which leads to the problem that the electricity is not fully utilized in the electrolysis of water due to heat loss.
