Embodiment

Followingly the utility model is described in detail with reference to drawings and Examples.

Fig. 1 is the structural representation of submersible type water flow generator of the present utility model; As shown in Figure 1, submersible type water flow generator of the present utility model comprises the housing 1 of forming its outward appearance.The both sides that housing 1 front end is relative are respectively arranged with a turbine 2 that is rotated in opposite directions by the current drive, and turbine 2 comprises the turbine shaft 3 and a plurality of turbine blades 4 that are installed on the turbine shaft 3 of central authorities.Housing 1 is fixed by positioning device, the front end that is housing 1 is formed with retaining ring 5, and fixedly an end of chain 6 is connected in the retaining ring 5, and the other end is connected with the anchor 7 that plays fixation, thereby will be suspended in submersible type water flow generator in the water fixedly in the certain limit, and can not drift about arbitrarily with ocean current.Housing 1 tail end is formed with tail vane 16 straight up, and tail vane 16 is a guiding device, and the leading role by tail vane 16 can make wind generator turbines 2 align water (flow) direction.
