Description

technical field [0001] The invention relates to a power generation device, in particular to a system and method for generating power by utilizing kinetic energy in a fluid pipeline (such as a natural gas pipeline network and a liquid pipeline network). Background technique [0002] At present, in the process of fluid pipeline transportation, since the monitoring and control devices are located in remote areas and far away from the power grid, this will cause power shortage or no power supply for monitoring, testing and other equipment, and there are hidden dangers. For example, there are many pressure adjustments during the natural gas transmission process The station is in a state of power shortage or no power supply due to its remote location, resulting in difficulty in power supply. Due to the remote location of these voltage regulating stations / boxes, it often occurs due to the lack of supply of mains power supply cables, and the necessary lighting and heating in winter. ...

[0002] At present, in the process of fluid pipeline transportation, since the monitoring and control devices are located in remote areas and far away from the power grid, this will cause power shortage or no power supply for monitoring, testing and other equipment, and there are hidden dangers. For example, there are many pressure adjustments during the natural gas transmission process The station is in a state of power shortage or no power supply due to its remote location, resulting in difficulty in power supply. Due to the remote location of these voltage regulating stations / boxes, it often occurs due to the lack of supply of mains power supply cables, and the necessary lighting and heating in winter. At the same time, because there is no external power supply, the monitoring system cannot be installed and used, and the data cannot be remotely monitored. It is necessary to send inspectors to inspect the site every day, and the uncertain safety hazards of pipe network equipment cannot be discovered in time. the manifestation

[0003] Aiming at the problem of power consumption of these voltage regulating stations at present, some experts proposed to apply to the power supply bureau for laying dedicated lines, but the construction cost is too high to realize. In addition, some technicians proposed a wind and light complementary power supply system, which is applied to gas pressure regulating stations / boxes It is a new idea, but there are regional restrictions and unstable power supply. In the existing technology, fluid motors are installed in pipelines to generate electricity to meet the electricity demand of the pressure regulating station itself. However, fluid motors must be installed in the natural gas pipeline network. In the medium and high pressure section, the pressure energy in the low pressure section cannot be utilized, that is, the use of fluid motors in pipelines with slow fluid flow rates cannot meet the power generation needs, and fluid motors cannot be directly installed in fluid pipelines, with complex structures and difficult maintenance

In addition, some technicians have proposed an energy-collecting pipeline fluid (flowing water, wind) power generation device, which fully collects the energy of the fluid (flowing water, wind) through a trumpet-shaped energy-collecting pipeline, and then converts the fluid energy into electrical energy through a generator. However, this kind of power generation device needs to remodel the pipeline, which is costly and complicated to install. Moreover, the application of this kind of power generation device is relatively limited. there is a great danger
