Abstract
The utility model relates to a mini self-excited power generation device, comprising a spiral spring, a speed change gear set and a mini self-excited generator, and the power generation device is provided with an on-off timing mechanism which controls the time amount of power generation. The on-off timing mechanism comprises a pair of ratchet wheel and a ratchet pawls which are engaged mutually in a timing gear case and an oriental gear which is arranged in an upper strip fixed ring gear box, the oriental gear is provided with a C type groove, a positioned and fixed pin which is matched with the groove is arranged in the upper strip fixed ring gear box, and the pin is penetrated in the groove. The utility model can change the output power of the device by changing the teeth number of a speed change gear which is connected with a rotation shaft where the generator is positioned. As the utility model is provided with the oriental gear and the positioned and fixed pin, and that the potential energy stored in the spiral spring is released by accident causing the due function of the utility model is prevented. The utility model has simple structure and reasonable structure, the power generation can be timed, and the output power can be changed.
Description
Technical field
The utility model relates to a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT), particularly a kind of miniature self-excitation Blast Furnace Top Gas Recovery Turbine Unit (TRT).
Background technology
A kind of portable self-generating illumination reel torch is disclosed among the China Patent No. ZL98244865.1, by shell, clockwork spring, change-speed gearing group, miniature self-excited DC generator, compositions such as germanium electrical equipment, clockwork spring fastening device, axle, speed limit gear, the gear ratio of change-speed gearing group is 12: 16: 20, and the output rotating speed is 360 rev/mins-560 rev/mins.The clockwork spring fastening device that is contained in the shell afterbody links to each other with clockwork spring by axle, is contained in the speed limit gear and the engagement of change-speed gearing group of axle.The output of change-speed gearing group links to each other with miniature self-excited DC generator by shaft coupling, and the output of miniature self-excited DC generator links to each other with germanium electrical equipment.The Blast Furnace Top Gas Recovery Turbine Unit (TRT) of this self-generating illumination reel torch does not have setting to prevent the safety device that clockwork spring is discharged unintentionally fully and can not regularly generate electricity, and makes us not too satisfied.
The utility model content
The purpose of this utility model is to provide a kind of simple and reasonable, the miniature self-excitation Blast Furnace Top Gas Recovery Turbine Unit (TRT) that can regularly generate electricity, can change power output, to overcome weak point of the prior art.
A kind of miniature self-excitation Blast Furnace Top Gas Recovery Turbine Unit (TRT) by this purpose design comprises scroll spring, change-speed gearing group, miniature self-exciting dynamo, and its architectural feature is the clutch timing mechanism that Blast Furnace Top Gas Recovery Turbine Unit (TRT) is provided with control generating dutation length.
Above-mentioned clutch timing mechanism comprises a pair of intermeshing ratchet and pawl that is arranged in the timing-gear box, and be arranged on bar and enclose oriental toothed gear in the gear box surely, this oriental toothed gear is provided with a C font groove, the location that bar encloses in the gear box surely that is arranged on of matching with this groove stops pin, and this pin is through in the groove.Gear on ratchet and the axle joins, and ratchet place axle joins by the rotating shaft of gear and generator; Oriental toothed gear directly or by a gear and axle joins; The locking direction and the oriental toothed gear of the ratchet and pawl direction that stops pin locking that is positioned is opposite.The bar spanner joins on the scroll spring and.The outlet of generator and a circuit board join, and this circuit board is provided with a full-wave bridge rectifier circuit and a LED light.A rotating shaft of generator place and a change-speed gearing join.
When the utility model uses, rotate counterclockwise the bar spanner and tighten scroll spring, the axle that joins with last spanner clockwise rotates by the gear driven oriental toothed gear, and an end of the C font groove in oriental toothed gear forwards the position that the location stops the pin place to; Meanwhile, axle clockwise rotates by the gear driven ratchet, does not stop between the ratchet and pawl that this is the thermal energy storage process of the utility model scroll spring.By changing gear and the gear ratio of oriental toothed gear and the length of C font groove of axle, can change the number of turns that scroll spring tightens, the energy storage capacity that just can change scroll spring is how much.When axle under the scroll spring effect, when clockwise rotating, ratchet and pawl blocks mutually, does rotating counterclockwise together; Oriental toothed gear also begins to do to rotate counterclockwise, and comparatively speaking, the location stops pin and forwards the other end to from an end of C font groove, and this is the utility model power generation process.The utility model can change the power output of this device by the number of teeth that changes the change-speed gearing that joins with the rotating shaft of generator place.The utility model can prevent that the potential energy that stores in the scroll spring from all being discharged unintentionally owing to be provided with oriental toothed gear and the location stops pin, causes the utility model to lose due effect.
The utility model is simple and reasonable, can regularly generate electricity, can change power output.
