Description

Technical Field

[0001] This utility model relates to the field of power supply technology for water conservancy projects, specifically to a prefabricated cabin-type hydrogen fuel cell power generation device suitable for water conservancy projects. Background Technology

[0002] Hydrogen energy, as an emerging clean energy source, is gradually becoming an important pillar of global energy transition and sustainable development due to its multiple advantages, including environmental friendliness, high energy efficiency, strong renewability, diverse application scenarios, and potential for cost reduction, demonstrating its enormous potential in energy transition and green development.

[0003] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. Its basic principle is the reverse reaction of water electrolysis, supplying hydrogen and oxygen to the anode and cathode respectively. As hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are released and reach the cathode through an external load. Fuel cells do not pollute the environment; they operate through an electrochemical reaction, rather than using combustion (such as gasoline or diesel). Fuel cells only produce water and heat, with no harmful emissions, low maintenance costs, and strong temperature adaptability.

[0004] A hydrogen fuel cell prefabricated cabin is a device that uses hydrogen fuel cells to provide electricity to end users. It uses hydrogen as a raw material and uses hydrogen fuel cells to convert the chemical energy in hydrogen into electrical energy, which is then transmitted to end users through power distribution facilities. It is characterized by high efficiency and cleanliness.

[0005] Water conservancy projects are generally located in remote areas with weak power grid infrastructure, resulting in poor reliability and stability of power supply. Therefore, there is an urgent need for a distributed prefabricated module power supply system for small and medium-sized water conservancy projects to provide them with better and more convenient power. To this end, a prefabricated module-type hydrogen fuel cell power generation device suitable for water conservancy projects is proposed. Utility Model Content

The interior of the prefabricated cabin body is divided into multiple areas, namely a hydrogen fuel cell cabin, a lithium battery energy storage cabin, an electrical system cabin, an electrical control cabin, an electrical fire protection cabin, and a heat dissipation cabin. The interior of the raw material supply cabin is a hydrogen storage cabin, which is connected to the hydrogen fuel cell cabin. The hydrogen fuel cell cabin is located on the side of the prefabricated cabin body closer to the raw material supply cabin. The lithium battery energy storage cabin and the electrical system cabin are sequentially arranged on the other side of the hydrogen fuel cell cabin.

[0009] The hydrogen fuel cell compartment is equipped with a fuel cell stack, the lithium battery energy storage compartment is equipped with a lithium battery energy storage module, and the electrical system compartment is equipped with an inverter, a dual power switching device, and a high-voltage distribution box.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The generator uses hydrogen as fuel to generate electricity.

[0024] Combination Figures 1 to 2 This embodiment provides a prefabricated cabin-type hydrogen fuel cell power generation device suitable for water conservancy projects, including a prefabricated cabin, which includes a prefabricated cabin body and a raw material supply cabin. The interior of the prefabricated cabin body is divided into multiple areas, namely a hydrogen fuel cell cabin 1, a lithium battery energy storage cabin 2, an electrical system cabin 3, an electrical control cabin 4, an electrical fire protection cabin 5, and a heat dissipation cabin 6. The interior of the raw material supply cabin is a hydrogen storage cabin 7, which is connected to the hydrogen fuel cell cabin 1. The hydrogen fuel cell cabin 1 is located on the side of the prefabricated cabin body closer to the raw material supply cabin. The lithium battery energy storage cabin 2 and the electrical system cabin 3 are sequentially arranged on the other side of the hydrogen fuel cell cabin 1.

[0025] The hydrogen fuel cell compartment 1 contains a fuel cell stack, the lithium battery energy storage compartment 2 contains a lithium battery energy storage module, and the electrical system compartment 3 contains an inverter, a dual power switching device, and a high-voltage distribution box. The electrical energy generated by the fuel cell stack is transmitted to the lithium battery energy storage module through a voltage stabilization system. The inverter receives the DC power from the lithium battery energy storage module and converts it into AC power. The inverter transmits the electrical energy to the high-voltage distribution box through the dual power switching device. The high-voltage distribution box is used to distribute the electrical energy, supply power to the electrical equipment inside the prefabricated compartment, and supply power to the external pump station and sluice gate.

[0026] The dual power switching device connects two power sources, one from the mains and the other from the inverter. The dual power switching device executes the commands issued by the high-voltage control cabinet to perform power switching and outputs electrical energy to the high-voltage distribution box.

[0027] In this embodiment, the fuel cell stack is a hydrogen fuel cell stack module, and a hydrogen fuel cell power generation system is composed of multiple hydrogen fuel cell stack modules. Hydrogen and oxygen undergo a chemical reaction within the hydrogen fuel cell stack to generate electricity and release heat. The coolant in the heat dissipation chamber 6 is used to maintain a stable temperature for the fuel cell. The lithium battery energy storage module includes multiple lithium iron phosphate battery clusters. Each lithium iron phosphate battery cluster includes a master control management unit, a slave control management unit, and battery cells. The slave control management unit is connected to the battery cells to form a battery pack. The battery pack and the master control management unit form a lithium iron phosphate battery cluster. Multiple lithium iron phosphate battery clusters are connected to form a lithium battery energy storage module. The battery clusters communicate with the low-voltage control cabinet in the electrical control chamber 4 to upload information such as battery status and power.

[0028] In this embodiment, the electrical control compartment 4 is located behind the electrical system compartment 3. The electrical control compartment 4 is equipped with a low-voltage control cabinet and a high-voltage control cabinet. The low-voltage control cabinet includes a human-machine interface display screen, and the high-voltage control cabinet is used to realize power supply signal detection and signal uploading.

[0029] Both the low-voltage control cabinet and the high-voltage control cabinet in this embodiment are existing technologies. The low-voltage control cabinet includes an energy management module and a human-machine interface display screen. The energy management module receives power demand, monitors the indicators of the hydrogen fuel cell, combines the command time and current magnitude required for gate control, and simulates the continuous state and duration of energy. When the conditions required for gate opening and closing are met, it issues a command to the hydrogen fuel cell to consume power. The energy management module can detect and analyze information such as the power level and status of the lithium battery in the lithium battery storage compartment 2. The human-machine interface display screen is the human-machine interface; operations on the display screen can simultaneously realize power supply control and automatic control system gate opening and closing. The environmental monitoring module within the display screen monitors the temperature, humidity, and operating status of the entire equipment. The high-voltage control cabinet has the functions of detecting the power quality of the output AC power and automatically switching between dual power sources. By detecting the power quality of the high-voltage distribution box in the electrical system compartment 3, it controls the output of AC power. When the power quality does not meet the requirements, it automatically cuts off the power supply and stops the output of power. The control unit in the high-voltage control cabinet is set with power supply priorities, such as mains power priority, hydrogen power priority, and alternating priority. Based on the set power supply priorities, it controls the dual power switching device in the electrical system compartment 3 to switch power sources.

[0030] In this embodiment, the electrical fire-fighting compartment 5 is located on the back of the lithium battery energy storage compartment 2. The electrical fire-fighting compartment 5 is equipped with a perfluorohexanone fire extinguisher, a smoke sensor, a temperature sensor, a hydrogen concentration sensor, and a fire control cabinet.

[0031] Specifically, the perfluorohexanone fire extinguisher is located on the top side near the inverter; the smoke and temperature sensors are both located on the top side near the electrical system compartment 3; and the hydrogen concentration sensor is located on the top side near the hydrogen fuel cell compartment 1. All the perfluorohexanone fire extinguishers, smoke sensors, temperature sensors, and hydrogen concentration sensors are electrically connected to the fire control cabinet. The fire control cabinet manages all fire protection facilities and is a crucial component. It integrates multiple functions, including fire alarm, fire extinguishing, smoke extraction, and evacuation guidance. It monitors the fire source through various sensors and activates the corresponding fire protection system as needed.

[0032] In this embodiment, the heat dissipation chamber 6 is located at the rear of the hydrogen fuel cell chamber 1. The heat dissipation chamber 6 is equipped with a heat dissipation system for cooling the fuel cell stack. Specifically, the heat dissipation system adopts a water-cooled heat dissipation system. The water-cooled heat dissipation system absorbs and removes excess heat from the fuel cell stack by circulating coolant inside the fuel cell stack, preventing overheating and ensuring stable battery operation.

[0033] In this embodiment, the hydrogen storage chamber 7 is equipped with a hydrogen storage tank and a hydrogen delivery system. The gas source input pressure of the hydrogen delivery system is 0.7 MPa to 35 MPa. The hydrogen from the hydrogen storage tank is delivered to the hydrogen fuel cell stack module through the hydrogen delivery system and the connecting pipe between the hydrogen storage chamber 7 and the hydrogen fuel cell chamber 1.

[0034] In this embodiment, the hydrogen fuel cell compartment 1 is also equipped with a ventilation component and a fan cooling system. The ventilation component includes louvers installed on the prefabricated compartment body, and the fan cooling system includes an exhaust fan installed on the prefabricated compartment body. The exhaust fan is an axial flow fan driven by a motor. The power supply of the motor is distributed by a high-voltage distribution box. Air enters the hydrogen fuel cell compartment 1 through the louvers and the exhaust fan and exchanges heat with the outside air to cool the hydrogen fuel cell compartment 1.

[0035] Specifically, the angle of the louver blades can be adjusted to control the entry and exit of air, thereby achieving effective convection of air inside and outside the hydrogen fuel cell cabin 1. This can help regulate the indoor temperature and improve air quality. The main function of the axial fan is to generate axial airflow by rotating blades, thereby achieving air exchange between the inside and outside of the cabin. The motor provides power to the axial fan.

[0036] The power generation device in this embodiment transmits the DC power generated by the fuel cell stack in the hydrogen fuel cell compartment to the lithium battery energy storage module through a voltage stabilization system. The lithium battery energy storage module then transmits the electrical energy to the electrical system compartment. The inverter in the electrical system compartment receives the DC power from the lithium battery energy storage module and converts it into AC power. In conjunction with a dual power switching device and a high-voltage distribution box, the AC power is then output. This enables the power supply to pump stations and sluice gates in water conservancy projects, as well as to the electrical equipment inside the prefabricated cabin.

[0037] The power generation unit has both off-grid and grid-connected power supply capabilities, while achieving zero emissions and zero pollution. The hydrogen storage chamber, hydrogen fuel cell chamber, lithium battery energy storage chamber, and electrical system chamber are located in separate chambers, achieving hydrogen-electricity separation. Furthermore, the system's operation and internal environmental safety status are monitored in real time through the electrical fire protection chamber, fully ensuring the safety of the system during operation.
