Description

Hydrogen Energy Uninterruptible Power Smart Street Light System

The present invention is a hydrogen energy uninterruptible intelligent street light system; in particular, it refers to an uninterruptible intelligent street light system used in areas without power grid, which mainly uses solar panels for power supply and hydrogen fuel cells for power supply to stably supply street light lighting power and provide intelligent protection and intelligent monitoring functions.

According to the common solar street lights on the market, they mainly generate and store electricity through solar panels to meet the needs of street lighting at night. However, when it is cloudy, rainy, or the solar panels are covered with dirty bird droppings, the light will become very dim, causing the power generation efficiency of the solar panels to drop to a very low level. This will lead to insufficient power supply from the solar panels, making the street lights unable to be activated normally. This will have a very big impact on the safety lighting of some remote areas or country roads, and will increase the crime rate and the safety of road users.

To solve this problem, for example, the Chinese patent publication No. CN105423218A discloses a street lamp, which includes a solar photovoltaic power generation system, a wind power generation system, a methanol-water reforming hydrogen generation system, a power conversion device, a power storage device, and a street lamp light module. The power generated by the solar photovoltaic power generation system and the wind power generation system is sufficient to charge the power storage device, and the excess power is then supplied to the methanol-water reforming hydrogen generation system for hydrogen production. During the operation of the street lamp light module, if the power level of the power storage device is lower than a preset value, the power storage device will be charged. When the power value reaches a low level, the methanol water reforming hydrogen generation system will be started, and the output electric energy will be converted by the electric power conversion device and then charged to charge the electric energy storage device, and supply power to the methanol water reforming hydrogen generation system itself and the street lamp lighting module. When the power of the electric energy storage device is higher than the high power value, it will shut down, and the electric energy storage device will supply power to the street lamp lighting module; the electric energy storage device is used to store electric energy and supply power to the street lamp lighting module, so that solar energy, wind energy and methanol water reforming hydrogen generation system can be combined to realize the three energy sources complementing each other to supply power to the street lamp.

However, after careful research, the inventor team of this case found that although the inventions are very ideal in theory and seem to be able to meet the demand for unlimited power supply for street lamps, they have no industrial utilization value when actually implemented and evaluated, resulting in the systems being unacceptable to owners and government agencies for the following reasons:

First, according to the lighting range of the lamps and the height of the lamp poles, the distance between street lights on general roads is about 16-45 meters. If each set of automatic power supply street light system is equipped with a more expensive hydrogen generation system, then the cost of each set of automatic power supply street light system will be very staggering. It is simply impossible for government agencies to allocate such a high budget at one time to build lighting systems for remote areas or sparsely populated areas. Therefore, in practice, this high-cost automatic power supply street light system is not feasible.

Second, the prior art uses the excess electricity generated by solar and wind power to produce hydrogen, and then uses the produced hydrogen to generate electricity when electricity is insufficient. This ignores the problem of insufficient sunlight (such as wetlands with frequent cloudy or rainy days) or insufficient wind in certain specific areas or locations. In this case, if solar and wind power cannot generate enough electricity, then the system will never be able to produce the required hydrogen, which will lead to unstable power supply and affect the normal operation of street lights.

Third, the methanol-water reforming hydrogen generation system is relatively complex and requires regular replenishment of methanol-water. If the excess electricity generated by solar panels and wind turbines is used to produce hydrogen from methanol-water, and the hydrogen generation system is used to supply electricity to street lamps when the solar panels and wind turbines are insufficient, the operation of the entire system will become quite complex. In addition to the very high manufacturing cost of the overall equipment, there will be more problems such as system errors that cause the equipment to be unusable. This is a very large workload for maintenance personnel who have hundreds or thousands of automatic power supply street lamp systems in an area. The cost of maintenance is also relatively high and the maintenance efficiency is poor, which is not practical and economical.

Fourth, the above-mentioned composite system including solar energy, wind energy and methanol water reforming hydrogen generation has very high manufacturing and maintenance costs, and there is also the risk of theft of important equipment. Since the automatic power supply street light system is installed independently and at a distance, and the automatic power supply street light system is mainly installed in smoke-free places where it is impossible to lay power grids, thieves can easily steal important equipment, or be damaged by other interested parties, and this behavior is difficult to be discovered, and the losses caused will be difficult to calculate, which will lead to the government's refusal to use such automatic power supply street light systems, and there is no value in industrial development.

To this end, the invention team, with many years of research and practical experience in AI, IoT, big data, blockchain, carbon inventory and carbon footprint, has conducted research on the above-mentioned issues and invented this case.

The purpose of the present invention is to provide an innovative hydrogen energy uninterruptible power intelligent street light system; it can integrate the controller, lamps, solar panels, hydrogen fuel cell modules, intelligent monitoring devices and intelligent monitoring devices into an automatic power supply street light system. The system mainly supplies power to the lamps through solar panels, and then uses the advantages of high power generation efficiency and high power generation of hydrogen fuel cell modules as an uninterruptible power system (i.e. UPS) to enable the lamps to stably illuminate at night, and through continuous and stable power supply, the street light can achieve the following functions: It can be used for big data analysis of recent security monitoring, weather monitoring and ecological records, and can assist in the installation of high-speed network base stations to realize the construction of high-speed networks for all roads and all areas with people entering and leaving, and assist in the connection and setting of community police networks in remote areas. It can also prevent the system from being stolen or maliciously damaged, greatly reducing manufacturing and maintenance costs, ensuring that the street light system maintains normal operation without power outages, and protecting community safety and equipment safety. In this way, the system can be accepted by government agencies and property owners and have practicality in society.

It should be emphasized that the hydrogen of the hydrogen fuel cell module used in this system is replenished by a hydrogen storage bottle replacement module, and the size and volume of the hydrogen storage bottle are designed according to the system device maintenance cycle and the gas valve that can monitor the flow and pressure. In this way, the hydrogen storage bottle can be replaced when the device is regularly maintained, or the power generation status of each smart street light system can be monitored at any time by detecting the pressure of the hydrogen storage bottle, and maintenance personnel can be dispatched in time to replace or replace the hydrogen storage bottle. The adjustment and maintenance of equipment ensures that the system can continuously and stably supply electricity to all equipment, which can effectively control the cost of hydrogen fuel cell modules. Through the solar hydrogen production station or hydrogen station set up in each area, a continuous and stable supply of hydrogen can be obtained, so that the system can supply electricity permanently and solve the power shortage crisis. Furthermore, the use of hydrogen fuel cell modules in this system can reduce carbon emissions, achieve the purpose of truly implementing environmental protection and carbon reduction, and realize the vision of net zero emissions.
