Abstract

The utility model relates to a float running water generator which can make use of the energy of the flowing water to generate the electricity. The float running water generator comprises a cylindrical float cylinder, a bracket, an impeller shaft, a gear-box and a generator. The impeller shaft is arranged along the direction of the water current and can be serially arranged according to the sizes of the water current and the electric energy production. The utility model can be directly arranged in the water current with the stream speed of more than 1M/S to generate the electricity, and has convenient usage and larger electricity-generating capacity. This float running water generator has simple and convenient structure, not only can be used in the river with deep water depth and rapid stream, but also can work in the small stream with shallow water depth. The float running water generator can also be used in the river in the countryside at the hilly region with abundant water resource.

Description

Float running water generator

The utility model relates to the floating-tube type flowing water power generation device that a kind of energy that utilizes water to flow generates electricity, and can be suitable for using in the little river of current resource than the streams, mountain area of horn of plenty and rural area.

Utilize the small-sized hydroelectric power generating apparatus generating can improve the situation of rural power service deficiency in the rural area, at present, hydroelectric power is normally generated electricity with the drop of water level, because it needs ponding to establish lock, implement to have brought inconvenience so give to use, and the investment of whole project is also bigger.Utilize mobile directly generating of water can avoid above-mentioned deficiency, but existing flowing water power generation device is mainly used in the rivers on the employed signaling lamp, because the impeller axis of this electricity generating device becomes vertical position to be provided with current, therefore be difficult for being provided with a plurality of impellers, require drinking water dark during use, its generated energy is less, and power supply quality is also relatively poor.

Task of the present utility model is to avoid above-mentioned deficiency and a kind of floating-tube type flowing water power generation device is provided, and it can be placed on directly generates electricity in the flowing water, not only uses very conveniently, and can have bigger generate output.

The utility model is realized by following scheme: have support 11, support top is equipped with the pillar buoy 2 that two ends have tie-plate 3, be provided with the coupling 4 that can rotate at the middle part of support 11, between coupling 4, be serially connected with rotating shaft 13, be equipped with impeller 14 in the rotating shaft 13, its head end and gearbox 10 link, and the output shaft of gearbox then links with a generator 8.

According to such scheme, when this device being positioned over small stream korneforos with certain water velocity, because the effect of floating drum 2 floats on whole device between the water surface, the tail end of device is held with rope and is made its location, and whole device vertically flushes with current because of flow action, at this moment, because of the percussion of current makes impeller 14 rotations, drive rotating shaft 13, through gearbox 10 raising speeds, drive generator 8 runnings, finish the task of flowing water generating.The utility model can be connected in series many rotating shafts a plurality of impellers are set, and therefore can produce bigger generated energy; The utility model does not need other auxiliary devices in use, needs only its placement positioning in flowing water, so use very convenient.In the more shallow place of current, whole device can be by support 11 supportings, as long as flow depth can still not influence its work by the submergence impeller.Floating drum 2 of the present utility model not only plays the whole device of supporting, but also plays the effect of rigid support, makes to the utlity model has intensity and rigidity preferably, and the impact of bearing current also makes structure of the present utility model comparatively simplify simultaneously.

Fig. 1 is an embodiment's of the utility model a structural drawing.

Fig. 2 is another embodiment's of the utility model a structural drawing.

Fig. 3,4 is the side view of two kinds of different structures of the utility model.

An embodiment of the present utility model such as Fig. 1,3, shown in 4, has columniform floating drum 2, floating drum 2 two ends are airtight also to have tie-plate 3, can connect a plurality of floating drums 2 so when needed, floating drum 2 links with support 11, mid-stent is provided with the coupling 4 that can rotate flexibly, support 11 bottoms shape triangular in shape, be convenient to support where necessary whole device, support 11 can be provided with several, between coupling 4, can connect rotating shaft 13 by coupling 12, impeller 14 is installed in the rotating shaft 13, impeller 14 connects firmly with rotating shaft 13 mutually by fixed cover 9, impeller 14 can be established two blades, the helix angle of impeller is 40 °-50 °, spacing between two impellers should be greater than impeller diameter, the front and back impeller blade is staggered to be installed, one end and the gearbox 10 of rotating shaft 13 link, gearbox is a raising speed mechanism, in umbrella gear 18 is arranged, 17 and

umbrella gear

16,15 two pairs of gear pairs, raising speed is than being 5:1, umbrella gear 15 live axles direct and generator 8 link, the generator 8 of present embodiment is a DC generator, being packaged in floating drum 2 interior ends is connected mutually with gearbox 10, the shell of gearbox 10 then links with the tie-plate 3 of floating drum, also can be provided with at the afterbody of whole device and to draw ear 1, so that fasten rope when using, rotating shaft impeller of the present utility model setting can have series type and and connect two kinds of structures of formula, as Fig. 3, shown in 4, series type is rotating shaft 13, support 11, floating drum 2 prolongs axially to be set up, and the formula that connects is three rotating shafts 13 of cross setting, three rotating shafts also can be prolonged axial serial connection and be increased, the rotating shaft tail end is equipped with belt pulley 20, the rotating shaft of both sides links to each other with intermediate rotary shaft 13 by belt 21, and give gearbox 10 with power transmission by the rotating shaft 13 of interposition, above-mentioned serial connection and and the mode that connects should set up or subtract according to the size of current and generated energy and establish, the increasing of impeller, subtract to establish and also can work to regulate driving force.

Another embodiment of the present utility model as shown in Figure 2, its basic structure is identical with the above embodiments, difference is that impeller 14 directly connects firmly in rotating shaft 13, gearbox 10 and generator 8 and rotating shaft 13 are along same axis setting, gearbox 10 can have two retaining or multi-gear transmissions, slewing range is at 5:1-10:1, gear shift mode can be realized by manual or magnetic clutch, manually structure is provided with handle sealing cover 9 outside gearbox 10, gearbox 10 directly links with generator 8, the head end of this external device can be provided with a manual rudder 7, locating piece 6 is set on tiller 5, the deflection that manual rudder can be used to regulate whole device and water (flow) direction is set, and the deflection by rotating shaft 13 and water (flow) direction reaches wheel speed, makes generator 8 operate in the optimum state.
