The power generating device in the invention can transform the clicking movement of fingers into electricity power and provide electricity power to the circuits in a computer, a calculator, an instrument or a meter; the invention has the advantages of novel property, uniqueness, energy saving and green earth.
Description
Technical field
The present invention relates to computing machine, counter and the used keyboard of other data recording device, particularly a kind of keyboard that has Blast Furnace Top Gas Recovery Turbine Unit (TRT).
Background technology
Prior art has computing machine, counter, the instrument and meter of data entry keyboard, the mancarried device that particularly has data entry keyboard all relies on battery or external power supply power supply, there is following defective: 1, waste energy, the use cost height, not environmental protection, and at no external power supply, or under the not good situation of powered battery, cause these devices to use; When 2, using key in data, need to point the frequent keyboard that knocks, rely on manpower to produce a kind of kinetic energy, this kinetic energy originally can utilize but and wasted.
Summary of the invention
The kinetic energy generating that task of the present invention produces when being to provide a kind of finger tapping key in data that can utilize the people, thus can be to the keyboard that has Blast Furnace Top Gas Recovery Turbine Unit (TRT) of circuit supplies such as corresponding keyboard and the computing machine that is connected thereof, counter, instrument and meter.
Task nationality of the present invention technical scheme and is achieved:
A kind of keyboard that has Blast Furnace Top Gas Recovery Turbine Unit (TRT) comprises keyboard body and mounted thereto by strong, be located at by strong down by strong switch, it is characterized in that have can be with by being good for the electromagnetic power generation apparatus that moves up and down and generate electricity by being good for described; Electromagnetic power generation apparatus comprise one with the described magnet that can thereupon move up and down by strong linking to each other, the relative static electromagnetic induction coil that is provided with magnet, the two ends of electromagnetic induction coil link to each other with rechargeable battery and external circuits by charging circuit; Magnet is the magnetic jar of sealing around a kind of top reaches, and electromagnetic induction coil places in the magnetic jar, and the centre of magnetic jar is provided with cylinder, and the electromagnetic induction coil internal diameter is greater than the external diameter of cylinder, and cylinder can be with passing in and out by strong motion in electromagnetic induction coil.
Described charging circuit is a diode rectifier circuit.
By such scheme as can be known: the present invention obviously provides the keyboard that carries Blast Furnace Top Gas Recovery Turbine Unit (TRT) of a kind of novelty, uniqueness, energy-conservation, environmental protection, the electronic installation of wearing this keyboard can dispense with outer connecting power, automatically finger is hit strong power and is converted into electric power to keyboard and circuit system power supply thereof.
