Description

Technical Field

[0001] This utility model relates to a mobile outdoor wind-solar hybrid hydrogen storage and energy supply device, specifically an outdoor energy supply device based on solar and wind power generation and hydrogen production and storage through water electrolysis, belonging to the field of new energy storage and distributed power supply technology. Background Technology

[0002] In remote areas and wilderness environments, existing energy supply methods face significant challenges. On the one hand, power grid construction is difficult and costly; on the other hand, existing field power supply devices rely excessively on fossil fuels, resulting in intermittent supply and exacerbating the ecological burden due to the large amounts of pollutants emitted during combustion. Therefore, developing clean field power supply devices is of great practical significance. Firstly, it can meet the energy needs of diverse activities. In activities such as field expeditions, geological exploration, and operations in remote areas, a reliable energy supply is fundamental to ensuring personnel safety and the normal operation of equipment. For example, when field expeditions venture deep into uninhabited areas, they need energy to maintain communication equipment to stay connected with the outside world and to power lighting equipment in the dark to ensure their safety. In geological exploration, the stable operation of various detection instruments is inseparable from energy; a sufficient energy supply ensures accurate and efficient data collection. Secondly, it can promote the development of remote areas. Many remote areas are geographically constrained and have difficulty connecting to the main power grid. Developing field power supply devices can provide these areas with stable electricity, promoting the development of local education and healthcare, such as providing power for multimedia teaching equipment in remote schools, powering medical equipment in rural clinics, and improving the quality of life for residents. Secondly, it enables emergency response. In natural disaster relief scenarios, traditional energy infrastructure in disaster areas is often damaged. Outdoor power supply devices can be quickly set up to provide energy for rescue equipment (such as life detectors and temporary lighting) and temporary shelters, facilitating efficient rescue efforts and ensuring the basic living needs of affected people. Finally, it promotes ecological environmental protection. Most traditional outdoor power supply devices rely on fossil fuels, leading to environmental pollution and carbon emissions. Developing clean outdoor power supply devices based on renewable energy can reduce environmental damage. For example, in nature reserves, clean energy power supply avoids the ecological disturbance caused by the use of fuel-powered generators, achieving coordinated development of energy utilization and ecological protection.

[0015] This invention provides a mobile, field-mounted wind-solar hybrid hydrogen storage and power supply device. Through wind-solar-hydrogen hybrid technology, it organically combines wind power generation, solar power generation, and hydrogen energy storage to form a highly efficient and stable energy supply system. The wind turbine and combined photovoltaic panels capture wind and solar energy respectively, and intelligent allocation and management are achieved through a wind-solar hybrid controller, ensuring the stability and reliability of the energy supply. This complementary design allows the device to continuously supply power under various weather conditions, effectively solving the problem of unstable energy supply in traditional clean energy power supply devices.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Because wind and solar energy are complementary in time and space—solar power generation is dominant during the day when there is ample sunlight, while wind power generation is dominant at night or on cloudy days when wind is relatively stable—combining the two can reduce the intermittent and fluctuating effects of a single energy source, providing a reliable and stable energy supply in the field. Therefore, this utility model's mobile field wind-solar hybrid hydrogen storage and power supply device adopts a wind-solar hybrid power supply method, integrating wind power generation and photovoltaic power generation. The overall structure is a vertical three-layer design: wind power is arranged on top to obtain greater wind resources; photovoltaic panels are arranged in the middle, employing a special "3+1" photovoltaic panel arrangement structure; and the cavity formed by this arrangement houses the power generation control equipment and power conversion equipment. The compact structure of this power supply device allows for rapid deployment in areas where energy is needed, providing a stable and sufficient energy supply for remote areas.

[0031] The "3+1" photovoltaic arrangement of the solar power generation section of this utility model involves placing a first photovoltaic panel 31 facing due south, a second photovoltaic panel 32 and a third photovoltaic panel 33 on either side (due east and due west), and a fourth photovoltaic panel 34 facing due north. The fourth photovoltaic panel 34 serves as a backup panel, capable of replacing photovoltaic panels that have degraded due to long-term operation. This arrangement is necessary because the sun's position and angle vary throughout the day, making it difficult for a fixed-position photovoltaic panel to receive all solar radiation. Therefore, this device employs a three-sided photovoltaic panel arrangement, effectively receiving solar energy from multiple directions, achieving high-efficiency power generation during the day, while eliminating the need for a tracking device, saving investment and increasing equipment reliability.

[0032] This invention utilizes renewable energy sources such as solar and wind power to generate electricity. The generated electricity is stored in a battery through a dual-path maximum power point tracking controller, ensuring that the photovoltaic panels and wind turbines operate at high efficiency.

[0033] This invention fully leverages the advantages of hydrogen and electricity as secondary energy sources, proposing a "wind-solar complementarity, electricity-hydrogen fusion" technical approach. It converts excess electrical energy, which cannot be stored in energy storage devices, into hydrogen energy for storage, thus avoiding the waste of solar and electricity. Hydrogen energy can effectively regulate the electrical capacity within the device. During periods of low electricity demand, excess electricity can be used for water electrolysis to produce hydrogen, which is then stored as hydrogen. During peak electricity demand periods or when renewable energy generation is insufficient, the stored hydrogen energy can be used to generate electricity through fuel cells, supplementing the electrical energy supply. This achieves a complementary supply of electricity and hydrogen energy, fully utilizing the advantages of hydrogen energy and providing a stable energy supply to remote areas, significantly improving their quality of life.

[0034] In this invention, the power supply device provides output ports for two energy sources simultaneously. When fuel is needed, hydrogen can be used directly as fuel by opening the hydrogen output port. When electricity is needed, the device can also convert the stored hydrogen into electrical energy in the fuel cell.

[0035] This invention employs a programmable DC-DC power module for intelligent control of hydrogen production power and is equipped with an adjustable electrolyzer (the output power and gas production of the electrolyzer can be controlled by the magnitude of the electrolysis current). This allows for flexible load adjustment according to actual needs, effectively improving hydrogen production efficiency. While ensuring sufficient power for the energy storage device, excess electrical energy is converted into hydrogen for storage. In the field, hydrogen can be used as fuel to provide heat, or it can be connected to an external fuel cell module to generate electricity, thus providing stable and reliable power support.

[0048] like Figures 1 to 9 The specific implementation method of the mobile field wind-solar hybrid hydrogen storage and power supply device provided by this utility model is as follows:

[0049] The mobile bottom chassis 9 adopts a steel structure frame, with internal insulation and moisture-proof layers. The chassis is formed by four panels: a front door panel 91, a rear door panel 92, a left fixed panel 93, and a right fixed panel 94.

[0051] The mobile bottom chassis 9 has a detachable support pole 2 on top, which is made of carbon fiber composite material and is 2 meters high.

[0052] The wind turbine generator 1 is a small permanent magnet generator with a rated power of 1 kilowatt, which is fixedly installed on the top of the pole 2 via the wind turbine flange 12.

[0053] The photovoltaic panel 3 uses monocrystalline silicon solar panels and consists of four panels: the first photovoltaic panel 31 faces due south, the second photovoltaic panel 32 faces due east, the third photovoltaic panel 33 faces due west, and the fourth photovoltaic panel 34 faces due north.

[0062] Full-day power generation efficiency test (using April operating data as an example)

[0063] Under normal lighting conditions, an average daily temperature of 21℃, and low wind speed (3m / s), this invention utilizes a 3+1 combination of polycrystalline silicon photovoltaic modules in its solar power generation system. The maximum power output of a single panel is 40W. On the day of the experiment, under the same sunlight conditions, the maximum output of a single panel was 28.00W, and the maximum output of the 3+1 photovoltaic panel was 49.27W. This demonstrates that the 3+1 photovoltaic panel design can effectively increase the total power generation and compensate for losses caused by solar energy offset. The wiring connections are shown in the attached diagram. Figure 10 As shown, the second photovoltaic panel 32 and the third photovoltaic panel 33 are connected in parallel and then in series with the first photovoltaic panel 31. This connection method can ensure that a high power generation level is always maintained, and the power generation voltage is high enough to charge the 24V battery. The wind power generation module adopts a vertical axis wind turbine 1, which has a relatively compact structure. The blades are made of engineering plastics, which are lightweight and have good field performance. The wind resistance strength reaches level 12, and the design wind speed range is 3-25m / s.

It prioritizes direct power supply from wind and solar power, with surplus energy stored or used for hydrogen electrolysis. The controller also features a wireless IoT module, enabling real-time monitoring of power generation and consumption data on mobile devices for convenient remote operation and maintenance. The device provides 5V DC and 220V AC output interfaces, supporting power for mobile phones, home appliances, and other devices. It can also directly output hydrogen for combustion or fuel cell power.

[0065] Implementation effect verification

[0066] The 3+1 photovoltaic panel system generates a total of 0.2 kWh of electricity per day, while the vertical axis wind turbine generates 0.1 kWh, bringing the total power output to 0.3 kWh. The battery capacity is maintained at 50%, and the battery voltage remains around 25.0V throughout the day, meeting all-weather power requirements. The entire process is zero-carbon emission, demonstrating significant practical benefits. Without additional energy input, the system's operating energy comes entirely from solar and wind power, with the battery capacity maintained at a constant level. However, the system is significantly affected by environmental factors (temperature, sunlight intensity, wind speed, etc.). Future research and fine-tuning of operating parameters under different temperature conditions will further explore and enhance the system's power generation potential and actual efficiency in diverse temperature environments.

[0067] Therefore, those skilled in the art can implement this utility model based on the above solution to meet the stable energy supply needs of the field and remote areas.
