The invention discloses a flywheel for generating renewable inertia kinetic energy and kinetic energy output equipment, and relates to the field of generation and use of the renewable inertia kinetic energy.
According to the first law of Newton's motion, namely the law of inertia, the generation of inertial kinetic energy is proportional to the diameter of the flywheel, the mass of the outer edge of the flywheel and the speed of the rotation of the flywheel. Therefore, the use of inertial kinetic energy is a matter of three aspects, namely the diameter of the flywheel, the mass of the edge and the rotational speed.
Specifically, a clutch, a gearbox and a speed change gear set are respectively arranged at two ends of one or a group of flywheels and flywheel shafts, so that an inertia kinetic energy flywheel is started from low speed to high speed to run, after inertia kinetic energy is generated, the inertia kinetic energy flywheel is transmitted to a load from the other end clutch through the gearbox and the speed change gear set, and the load also continuously and permanently works after being started from low speed to high speed, such as power generation of a generator.
The power source is such as engine, motor, etc. taking the engine as an example, the clutches at two ends of the inertia kinetic energy flywheel are in a separation state, namely, a neutral position, after the engine is normally started, the first clutch is stepped down to stir the first gearbox speed regulating rod to enable the inertia kinetic energy flywheel to rotate from low speed to high speed to generate inertia kinetic energy, then the second clutch is stepped down to stir the second gearbox speed regulating rod to enable the inertia kinetic energy to be transferred from low speed to high speed to a load, and the whole process of producing inertia kinetic energy from the power source through the inertia flywheel to do work is completed. The inertial kinetic energy can continuously work for a long time as long as the power source does not disappear, and it needs to be stated that the utilization rate of the inertial kinetic energy should not exceed 70% of the power of the inertial kinetic energy, so that the inertial flywheel can stably operate for a long time to work without overload and stop. The inertial flywheel and the main shaft are supported by a bracket to rotate.
The inertial kinetic energy output flywheel technology is an inexhaustible renewable energy source after liquid air energy source is discovered. The inertia kinetic energy is the existing non-renewable resource which is prevented from being over developed, and has the following advantages: 1. can be regenerated; 2. compared with wind power and photovoltaic power generation, the artificial controllability is high; 3. compared with the problems of no site selection and no nuclear waste in hydropower and nuclear power; 4. compared with coal power, the method has no pollution problem; 5. compared with gas turbine power generation, the method has the advantages of less equipment investment in the early stage, low technical requirement, less used fuel and low unit power generation cost; 6. the inertial kinetic energy flywheel technology of the present invention reduces pollution and emissions due to reduced energy consumption.
