Description
Technical Field
The invention belongs to the technical field of nano power generation, and particularly relates to a multi-energy power generation micro-nano bag and an energy collection array suitable for fluid transportation pipeline nodes.
Background
Pipeline transportation is an important transportation mode in the transportation industry, the pipeline transportation has own specific advantages, such as high efficiency, small pollution, low cost and small influence by the outside, so almost all fluids are transported by pipelines, and the pipeline transportation is rapidly developed in recent years.
The fluid transportation pipeline comprises an upper water pipeline, a lower water pipeline, a heating hot water pipeline, a long-distance oil transportation pipeline, a natural gas transportation pipeline and other energy transportation pipelines which are buried underground, and oil transportation, gas transportation and water transportation pipelines which are difficult to directly observe and visually inspect in buildings, large-scale fluid storage and transportation equipment, airplanes and ships.
Since the 21 st century, the application and development of microelectronic technology plays a crucial role in the social intelligence process, and with the demand for more intellectualization, miniaturization and autonomy of instruments and equipment, a high-efficiency miniature energy collecting device is undoubtedly an important breakthrough. Since the first zinc oxide nanowire-based micro-generator appeared in 2000, the nano-generation technology developed rapidly, and various nano-generators based on various principles appeared in the world, including piezoelectric ceramic technology, friction power generation technology, bioelectricity technology, and magnetic induction technology, and the power generation principle of the existing nano-generator is as follows:
the piezoelectric film power generation principle is that when some dielectric medium is deformed by external force along direction, its interior can produce polarization phenomenon, at the same time two opposite surfaces of the dielectric medium produce positive and negative opposite charges, and when the external force is removed, it can be restored to uncharged state, said phenomenon is called positive piezoelectric effect, and when the direction of the applied force is changed, the polarity of the charge can be changed, so that at present, more piezoelectric materials can be used, such as fine-grain piezoelectric ceramics, PbTiO3 series piezoelectric materials and piezoelectric ceramics-high polymer composite materials.
The principle of electromagnetic power generation is that when parts of conductors of a closed circuit do cutting magnetic induction line movement, the phenomenon that current is generated on the conductors is called electromagnetic induction phenomenon, the generated current is called induced current, and the potential is called induced electromotive force, the magnitude of the induced electromotive force is related to the speed of change of magnetic flux passing through the closed circuit, and the formula of the induced electromotive force is as follows:
the principle of friction film power generation is that when two materials rub against each other, of the materials must lose electrons because of the different abilities of atomic nuclei of different materials to bind extra-nuclear electrons, and of the materials must get redundant electrons, so that frictional charges are formed on the contact surfaces of the two materials.
Card vortex street principle, when a steady stream under fixed conditions bypasses some objects, two sides of the objects will periodically shed out double-row line vortexes which are opposite in rotation direction and are arranged regularly, at the beginning, the two lines of line vortexes respectively keep moving forwards, then the two lines of line vortexes interfere with each other and attract each other, and the interference is larger and larger, so as to form a nonlinear so-called vortex street, card vortex street is phenomena studied by viscous incompressible fluid dynamics, and contains fixed energy.
The principle of object suspension: the pressure of the lower surface of the object in the gas is greater than the pressure of the upper surface of the object in the gas, so that the resultant force is the vector sum of the upper surface pressure and the lower surface pressure, and when the vector is equal to the gravity of the object in value and opposite in direction, the object can be suspended in the gas medium. Buoyancy formula:
the energy existing in the fluid pipeline cannot be effectively recycled or is difficult to be effectively recycled through a large device, and the nano power generation device manufactured by utilizing the microelectronic technology can effectively utilize various types of energy in the pipeline, so that the aim of providing energy for the transportation pipeline or related facilities at the periphery is fulfilled.
