Fig. 1, shown in 2, the utility model before use, stir bar 14 manually, the impeller disk 9 and matched connecting tube 9-1, four guiding Bar 10 is all put into upper end the first sheaf space 1-1 of cabinet 1, convenient storage and carrying when not in use.User is at field family It is carried when outer tourism exploration or investigation, when exoelectron product (such as smart phone) out of office is without electricity, if surrounding does not have The brook of flowing is directly installed in place bar 14 is stirred manually, is then shaken with hands the handle for stirring bar 14 manually clockwise, is stirred manually The adjustable pipe 14-3 of bar 14 is rotated along handle 14-2, it is therefore prevented that manpower directly contacts handle 14-2 rotation and causes skin abrasion, hand The dynamic bar 14 that stirs drives the first driving gear 5 to rotate clockwise, and the first driving gear 5 drives the first driven gear 6 and second driven Gear 7 rotates counterclockwise, and the second driven gear 7 drives third driven gear 8 to rotate clockwise, and third driven gear 8 drives small The power input shaft 4-1 of type dc generator is rotated, since 7 number of teeth of the second driven gear (23 tooth) is more than the first driven gear 6,7 number of teeth of third driven gear, the number of teeth (33 tooth) of the first driving gear 5 are more than the number of teeth of the second driven gear 7, so, hand It shakes after stirring 14 handle of bar manually, the revolving speed of small-sized DC generator power input shaft 4-1 can be increased, then, at higher turn Under speed, for the Inside coil of small-sized DC generator in the magnetic action power of inner magnet, cutting magnetic line, which produces electricl energy, exports 12V The DC power supply of left and right enters the power input of voltage regulator circuit 12, and (specific voltage levels depend on manpower and shake to stir bar 14 manually Handle revolving speed), 12 internal circuit of voltage regulator circuit effect under, voltage regulator circuit 12 export 5V DC power supply for charging plug insert Enter electrical equipment (such as smart phone) charging of USB power source socket, while extra electric energy is stored by 5V battery 13.When out of office When exoelectron product (such as smart phone) is without electricity, if surrounding has brook, the river of flowing, user is four guide rods 10 Upper end is separately mounted in four fixing pipes 11, by adjusting four 10 upper ends of guide rod respectively in four fixing pipes 11 Highly, the utility model whole height is adjusted, after height adjustment is good, user is with four hand screw 11-1 of hand handle respectively along interior spiral shell Line aperture screws, can be four guide rods after on the inside of four hand screw 11-1 and four 10 sides of guide rod are in close contact 10 upper ends are fixed on respectively in four fixing pipes 11, and four guide rods 10 are then inserted into small stream side or the river bank small stream edge or river Edge, guarantee stream or river water flood 9 lower part of the impeller disk can be (if water shallowly can also directly be inserted directly into four guide rods 10 It is water-bed), stream or river water the impulsion impeller disk 9 of flowing rotate clockwise, and the impeller disk 9 drives the power of small-sized DC generator 4 Input shaft 4-1 rotation, under higher rotation speed, the Inside coil of small-sized DC generator 4 is cut in the magnetic action power of inner magnet It cuts the magnetic line of force and produces electricl energy the DC power supply of output 12V or so and enter power input (the specific voltage levels of voltage regulator circuit 12 Depending on water velocity), under the effect of 12 internal circuit of voltage regulator circuit, the 5V DC power supply that voltage regulator circuit 12 exports is charging Plug is inserted into electrical equipment (such as smart phone) charging of USB power source socket, while extra electric energy is stored by 5V battery 13； Due to small unidirectional bearing 3, only hand to start to stir bar 14 when rotating clockwise, the inner ring of unilateral bearing 3 is clockwise The outer ring that rotation just will drive unilateral bearing 3 is servo-actuated, then the first driving gear 5 also just can rotate, when the impeller disk 9 turns clockwise It when dynamic, is acted on through third driven gear 8, the second driven gear 7, the first driven gear 6 can rotate counterclockwise, the first driven gear 6 will drive the first driving gear 5 and the outer ring of unilateral bearing 3 rotates clockwise, since the outer ring of unilateral bearing 3 turns clockwise Dynamic, the inner ring of unilateral bearing 3 can be in stationary state, and the outer ring of discord unilateral bearing 3 is servo-actuated, and which prevent water flow impulsion leaves Wheel disc 9 rotates, and is stirred manually in rotary state when bar 14 is not removed, brings unnecessary rotation to hinder to the rotation of the impeller disk 9 Power.The utility model is using the water flow impulsion impeller disk 9 power generation because not needing using manpower, and have persistence, therefore be field Generate electricity the first choice used, but field does not ensure that there are the stream or small river water of flowing at the moment, therefore, uses in emergency Hand power is also spare choosing.It, can also be straight when stream or river water side can not find suitable installation place really in actual use It connects and uses hand power.The utility model user can be handy to carry about and be stored conveniently, not only can be by temporary manually in use Shi Fa electricity is electronic product charging, moreover it is possible to which under conditions of having streams, the kinetic energy that the flowing of effective use streams generates is power generation Machine power generation, and then power for electronic product, when guaranteeing field electronic product without electricity, electronic product, which can facilitate, to charge, and can give Outdoor travel exploration or investigate is brought convenience, based on above-mentioned, so the application prospect that the utility model has had.
