Detailed Description
In order to more clearly illustrate the technical solution of the present invention, the drawings used in the description will be briefly introduced, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other embodiments can be obtained according to the drawings without inventive labor.
As shown in fig. 1:
the running machine, the elliptical machine, the exercise bicycle, the stair machine, the spinning bicycle and the like are provided with a rotating end for driving a rotating end exercise device 1 to be connected with a rotor of a generator 2, the generator 2(AC) is connected with a controller 3 for converting alternating current into direct current (AC/DC), the controller 3 is respectively electrically connected with an instrument and a grid-connected inverter 5 for converting the direct current into the alternating current (DC/AC) or an off-grid inverter 6 for converting the direct current into the alternating current (DC/AC), the off-grid inverter 6 is connected with an illuminating lamp (or other electrical appliances) and provides power, and the grid-connected inverter 5 is connected with an external power grid 7.
As shown in fig. 2:
one of the core components of the invention is a generator 2 and a controller 3 thereof, a user moves to drive a rotor of the generator 2 to rotate, the rotor and a stator magnetic circuit of the generator 2 do circular magnetic line cutting motion, and electric energy is generated and sent to the controller 3.
The controller 3 converts three-phase alternating current into direct current and then outputs the direct current in two paths, one path of direct current is input into the off-grid inverter 4, the off-grid inverter 4 converts the direct current into alternating current to supply power to a power grid or household appliances and provide the alternating current for an instrument (12V or other) direct current power supply.
As shown in fig. 3:
the user moves to drive the rotor of the generator 2 to rotate, and the rotor and the stator magnetic circuit of the generator 2 do circular magnetic line cutting motion, so that electric energy is generated and sent to the controller 3.
The controller 3 converts three-phase alternating current into direct current and then outputs the direct current in two paths, the other path of direct current is input into the grid-connected inverter 5, the grid-connected inverter 5 converts the direct current into alternating current, and an alternating current power supply which is connected with an external power grid 7 in a grid mode is provided to consume electric energy in the generator, so that magnetic flux resistance of the generator 2 is increased, and the current output by the alternating current power supply which is connected with the external power grid 7 in the grid mode can be adjusted effectively.
As shown in fig. 4:
the working principle of a control system consisting of the generator 2 and the controller 3 thereof is as follows:
starting, powering on the equipment, and recovering the equipment to a default state;
the controller 3 converts the resistance value set by a user or a default resistance value into a corresponding current value of the inverter grid-connected alternating current power supply regulated by the generator 2 through the controller 3, and acts on the electromagnetic resistance of the generator 2 connected with the fitness equipment 1 in the movement direction to generate a corresponding resistance value;
and after the user stops acting, the terminal control equipment enters a standby mode.
Under the same rotating speed of the grid-connected and off-grid power generation systems, the regulating controller 3 manages the input and output current of the circuit of the grid-connected or off-grid inverter 5, when the output current is increased, the output power is increased, and the work done on the power grid is also increased due to the increase of the input power of the grid-connected inverter 5. The magnetic flux (resistance) of the generator 2 works and the resistance increases and vice versa.
Therefore, energy generated when various equipment such as the running machine, the elliptical machine, the exercise bicycle and the like are used can be converted into electric energy to be fed back to a power grid in a grid-connected mode or be supplied to a user in an off-grid mode, and double effects of exercise and fitness and green energy are achieved.
