Detailed Description
The utility model provides a magnetic current body electricity generation floor, for making the utility model discloses a purpose, technical scheme and effect are clearer, clear and definite, following right the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 to 4, the embodiment provides a mhd floor, wherein, as shown in the figure, the mhd floor includes a floor body (not shown), a connection module 200 disposed inside the floor body, and at least two power generation modules 100 electrically connected through the connection module 200, the power generation modules include a base 40 provided with a groove 13, a first electrode layer 10 and a second electrode layer 20 disposed inside the base 40, and a permanent magnet 30 disposed above the base 40 and abutting against an inner surface of the floor body, the first electrode layer 10 and the groove 13 form a sealed cavity, a mhd (not shown) is disposed in the sealed cavity, and the second electrode layer 20 is disposed above the first electrode layer 10 at intervals; the floor body drives the permanent magnet 30 to move under the action of external force, the permanent magnet 30 is used for controlling the magnetic fluid to move in the sealed cavity, and the magnetic fluid drives the first electrode layer 10 and the second electrode layer 20 to generate electricity through friction.
In this embodiment, the floor body is made of a polymer material with certain elasticity, when the floor body is stepped on, the permanent magnet abuts against the inner surface of the floor body, the floor body can drive the permanent magnet in the power generation module to move up and down under the action of external force, and when the permanent magnet moves down, the distance between the permanent magnet and the magnetic fluid is gradually reduced; when the permanent magnet moves upwards, the distance between the permanent magnet and the magnetic fluid is gradually increased.
Specifically, when the distance between the permanent magnet 30 and the magnetic fluid in the sealed cavity is long, the magnetic fluid is not magnetized, the magnetic fluid does not generate acting force on the first electrode layer, and at this time, because a gap exists between the first electrode layer 10 and the second electrode layer 20, collision and friction are avoided, and electric energy is not generated; when the distance between the permanent magnet 10 and the magnetic fluid is short, the magnetic fluid is magnetized, the magnetic fluid can generate acting force on the first electrode layer, so that the first electrode layer 10 is gradually deformed, the gap between the first electrode layer 10 and the second electrode layer 20 is gradually reduced, collision and friction occur, and the power generation module generates electric energy.
In some embodiments, when the magnetization distance between the permanent magnet 30 and the magnetic fluid is within 1-20mm, the magnetic attraction force of the permanent magnet can be ensured to be effective, that is, when the permanent magnet approaches the magnetic fluid to be within 1-20mm, the power generation can be realized. When the permanent magnet moves towards the direction far away from the magnetic fluid after reaching the magnetization distance, the magnetic fluid is demagnetized, the acting force of the magnetic fluid on the first electrode layer is weakened and disappears, the first electrode layer gradually recovers deformation, and finally the gap between the first electrode layer and the second electrode layer recovers. The magnetization and demagnetization of the magnetic fluid can be controlled by the movement of the permanent magnet, so that collision and friction are continuously generated between the first electrode layer and the second electrode layer to generate electric energy. In this embodiment, since the permanent magnet is not in contact with the first electrode layer (or the magnetic fluid), the non-contact pushing manner greatly reduces the microscopic instability caused by human operation errors, and further improves the voltage output stability of the power generation floor.
In some specific embodiments, the permanent magnet is a permanent magnet.
In some embodiments, the at least two power generation modules may be connected in series or in parallel by the connection module. Specifically, when the magnetofluid power generation floor needs to obtain a larger current, a plurality of power generation modules can be connected in parallel through the connection module; when the magnetofluid power generation floor needs to obtain larger voltage, a plurality of power generation modules can be connected together in series.
In some embodiments, as shown in fig. 4, the first electrode layer 10 includes a first PET film 11 and a first ITO film 12 stacked in sequence from bottom to top along the groove opening direction; the second electrode layer 20 comprises a PDMS film 21, a second ITO film 22 and a second PET film 23 which are sequentially stacked from bottom to top along the opening direction of the groove, the second electrode layer 20 is arranged above the first electrode layer 10 at intervals, namely a gap is arranged between the first electrode layer and the second electrode layer, and the surface of the PDMS film 21 and the surface of the first ITO film 12 are respectively an upper friction surface and a lower friction surface during friction power generation. In this embodiment, the first PET film in the first electrode layer is in direct contact with the magnetic fluid, and seals the magnetic fluid in the groove of the base.
In this embodiment, after the magnetic fluid is magnetized by the permanent magnet, the magnetic fluid moves along the direction of the permanent magnet and applies an acting force to the first electrode layer, the first electrode layer deforms under the acting force and collides and rubs with the second electrode layer, electrons are easily lost on the surface of the first ITO film due to the difference of the rubbing electric polarities, and electrons are easily obtained on the surface of the PDMS film; therefore, when the magnetic fluid drives the first ITO thin film to collide and rub with the PDMS thin film, electrons are transferred from the surface of the first ITO thin film to the surface of the PDMS thin film, so that charges with equal quantity and opposite signs, namely friction charges, are carried on the surfaces of the two thin film layers; when the upper and lower friction surfaces (the first ITO film surface and the PDMS film surface) are separated slowly under the action of no external force, a potential difference is generated between the two friction surfaces, the PDMS film with negative charges repels electrons on the electrode borne by the PDMS film due to electrostatic induction, and if the electrode borne by the PDMS film and the electrode borne by the first ITO film are connected through a load, the electrons flow under the driving of the potential difference to balance the potential difference between the upper and lower friction surfaces, namely, current is generated in an external circuit. When the external force is no longer applied and the gap distance between the two friction surfaces reaches the maximum, the upper and lower friction surfaces and the electrodes carried on the upper and lower friction surfaces are in static balance state, no electron moves in the external circuit, and the current is zero.
Compared with the existing power generation floor, the magnetofluid power generation floor provided by the embodiment adopts a non-contact type pushing mode, so that the microscopic instability caused by manual operation errors is greatly reduced, and more stable voltage output is realized; the magnetofluid power generation floor is simple in structure, low in processing cost and low in requirement on environment, can be applied to extreme environments such as dust and underwater, and greatly improves stability, reliability and economy of the magnetofluid power generation floor. Furthermore, the magnetofluid power generation floor provided by the embodiment has the advantages of simple structure, compact design, relative independence of all parts, convenience in maintenance and overhaul, good interchangeability, and capability of realizing modularization, serialization and rapid design.

The first output lead and the second output lead adopt a design mode of a bow-shaped folding line, so that current transmission is facilitated, deformation and deformation recovery are facilitated, and the service life of the power supply is prolonged.
In another specific embodiment, as shown in fig. 6, in order to also facilitate the rapid and efficient transmission of the energy generated by the flexible power generation film with magnetic adhesive to the external circuit, the first output lead is attached to one side of the first PET film, which is close to the first TIO film, in a ring shape; the second output lead is attached to one surface, close to the second ITO film, of the second PET film in an annular mode.
In some embodiments, the first output conductive line is directly electrically connected to the first ITO thin film, and the second output conductive line is directly electrically connected to the second ITO thin film.
In some embodiments, the first output wire and the second output wire are independently selected from one of silver, copper, gallium indium alloy, or gallium indium tin alloy, but not limited thereto.

The nano ferroferric oxide particles are dispersed in the base carrier liquid through the dispersing agent, and the nano ferroferric oxide particles perform disordered movement in the base carrier liquid in the absence of the influence of a magnetic field, which is similar to Brownian movement. The nano-sized magnetite particles are magnetized and then move regularly due to the influence of the magnetic field of the permanent magnet, and the entire nano-sized magnetite particles are formed to be oriented toward the permanent magnet 30 (of course, the individual nano-sized magnetite particles are not necessarily oriented toward the permanent magnet although they are influenced by the magnetic attraction force). Thus, the magnitude of the force of the magnetic fluid against the first electrode layer can be controlled by the minimum distance between the permanent magnet and the magnetic fluid.
In this embodiment, the higher the volume ratio of the nano ferroferric oxide to the base carrier fluid is, the higher the output voltage is, and otherwise, the lower the output voltage is; preferably, the volume ratio of the nano ferroferric oxide to the base carrier liquid is 20-50%.
