Description

Technical Field

[0001] This invention relates to the field of composite energy technology, specifically to a microgrid energy storage and power supply device for power stations that combines an AEM stack fuel cell with photovoltaic panels. Background Technology

[0002] With the rapid development of information technology and MEMS (Micro-Electro-Mechanical Systems), unattended miniaturized devices, represented by wireless sensor networks, are widely used in military, disaster relief, and environmental fields. These unattended devices are mostly placed in outdoor environments, and some require high concealment. Therefore, these devices need to maximize integration density, reduce size and weight, and achieve continuous, stable, and highly reliable autonomous power supply over a working cycle of several months. For these unattended miniaturized devices, the power supply unit typically accounts for the largest volume proportion of the entire system; therefore, improving the integration density of the power supply unit and the stability and lifespan of the power supply is of great significance.

[0003] A traditional microgrid for a power station that combines an AEM stack with solar panels mainly consists of a solar panel array, an AEM stack combined with a fuel cell (including the AEM stack, hydrogen supply system, and hydrothermal management module), a battery storage bank, a bidirectional inverter, an energy management system (EMS), and a load distribution unit. Before use, the connection status of each component is checked, and the energy management system is initialized. During the day, solar panels generate electricity first, and the inverter converts the DC power to AC power to supply the power station load. Excess electricity is rectified and stored in the battery storage bank or directly powers the fuel cell auxiliary system.

[0004] As a device, photovoltaic power output is significantly affected by light intensity, temperature, and weather conditions such as cloudy days and dust storms. Furthermore, long-term operation leads to component efficiency degradation, which directly results in unstable system energy input. During the day, light intensity fluctuates with time of day, such as being weak in the morning and evening and strong at noon. Cloud cover causes a sharp drop in power output, while there is no output at night. This causes frequent start-stop of fuel cells or a sharp increase in the charging and discharging pressure of energy storage systems, and may even affect the stability of the load power supply. Summary of the Invention

[0040] Reference Figures 6-8A hollow rod 54 is fixedly installed on the support frame 5, and a base 541 is fixedly installed on the hollow rod 54.

[0041] Reference Figures 5-8 A fixed frame 61 is fixedly installed at the edge of the photovoltaic panel 6, and a fan 62 is rotatably installed inside the fixed frame 61. The distance between each fan 62 is the same, and the fans 62 are interconnected by connecting lines. The fans 62 installed on the fixed frame 61 enable the airflow to drive the fans 62 to rotate and generate mechanical energy when the device is in use. This mechanical energy is then converted into electrical energy by the device for storage, avoiding frequent start-stop of the AEM fuel cell or a sharp increase in the charging and discharging pressure of the energy storage system, and ensuring the safety of the device during use.

[0042] Reference Figures 5-8 Two parallel supports 620 are fixedly installed on the upper surface of the photovoltaic panel 6, and a reciprocating screw 63 is rotatably installed between the two supports 620. A scraper 64 is threaded onto the reciprocating screw 63. A pulley 631 is fixedly installed at the center of both the reciprocating screw 63 and the fan 62, and the two pulleys 631 are connected by belt drive. Through the supports 620 installed on the photovoltaic panel 6, when the airflow drives the fan 62 to rotate, the rotation of the fan 62 shaft can drive the pulley 631 to rotate, and the belt drives the reciprocating screw 63 to rotate, thereby driving the scraper 64 to move back and forth and remove impurities from the surface of the photovoltaic panel 6.

[0043] Reference Figures 5-8 A guide rod 65 is fixedly installed between the two brackets 620, and the guide rod 65 is parallel to the reciprocating screw 63. The scraper 64 is slidably connected to the guide rod 65. The guide rod 65 installed on the bracket 620 can ensure that the scraper 64 will not tilt during movement.

[0044] Reference Figures 1-3 The length of the scraper 64 is equal to the length of the photovoltaic panel 6. By setting the size relationship between the scraper 64 and the photovoltaic panel 6, the stable operation of the device is ensured.

[0045] Specifically, the solution is as follows: When using the device, the operator first moves it to the predetermined position and fixes it in place. The support columns 11 on the base plate 1 provide support for the device body. Simultaneously, the support columns 11 are positioned at the corners of the base plate 1 to ensure stability. The horizontal bars 21 on the base plate 1 allow the control frame 5 to rotate vertically. The bearing plate 52 and telescopic rod 53 on the support frame 5 allow for longitudinal adjustment of the support frame 5, ensuring that the photovoltaic panel 6 faces the sunlight directly, thus guaranteeing the stability of its power generation. Airflow drives the fan 62 to rotate. When the device generates mechanical energy, the collected green electricity can be used by the AEM fuel cell in the device to perform water electrolysis. The hydrogen produced by the AEM fuel cell electrolysis can be collected and stored by the hydrogen storage tank 73 inside the device, and then provided to the mobile base station through the AEM fuel cell. This avoids frequent start-stop of the fuel cell or a sharp increase in the charging and discharging pressure of the energy storage system, ensuring the safety of the device during use. When the airflow drives the fan 62 to rotate, the rotating fan 62 shaft can drive the pulley 631 to rotate, and through the belt, drive the reciprocating screw 63 to rotate, thereby driving the scraper 64 to move back and forth and remove impurities from the surface of the photovoltaic panel 6.
