Described rotating seal ring is provided with annular recess, and the cross section of rotating seal ring is M shape.
The annular recess of described rotating seal ring is a V-ring shape groove.
The bearing that described rotating shaft is provided with comprises 1 and compresses bearing, compresses bearing and is positioned at the centre bearing hole at the seat of honour and is pressed on the rotating seal ring, is provided with pressure ring in the seat of honour, and the pressure ring and the seat of honour are spirally connected, and pressure ring is pressed in and compresses on the bearing.
Described circuit board is connected in the upper end of coil brace, and circuit board is between coil brace and end cap.
Working procedure of the present utility model is as follows:
The utility model directly or by connecting tube is installed on the water pipe, and when the pressure flow in the water pipe flowed, current entered from the feed-water end of straight-through base, and the aperture through being located at the feed-water end inwall enters impeller cavity, and to the blade impact of impeller, impeller begins to rotate.Because the water outlet of impeller cavity is located at its bottom, the direction of the direction of water impact impeller blade and impeller cavity water outlet can be plumbness, i.e. current water outlet direction is the axial of impeller.So the kinetic energy of current is not wasted.Current enter diversion cavity through the impeller cavity water outlet, enter the waterexit end under the guiding of guide plate, flow out from the waterexit end.In the wheel rotation process, drive rotating shaft and rotate, rotating shaft drives rotor rotation, the stator cutting magnetic line, and the electric current of generation is received circuit board, is external to the electricity consumption device after circuit board is handled.
Compare with the existing hydroelectric generator that is mainly used in running water pipe, the utlity model has following obvious advantage:
Because waterexit end and feed-water end are same shaft axis, the utility model promptly forms the structure of straight-through type, thereby has avoided the shortcoming of the curved formulas of 90 degree, installs and uses very convenient.Because rotating seal ring is provided with annular recess, its cross section is M shape, so rotating seal ring self has the elasticity of radial dilatation, can effectively prevent to leak from the axial generation of rotating shaft; And be provided with pressure ring again, can make axial pressure to compressing compressing of bearing to rotating seal ring by pressure ring, make rotating seal ring keep radial dilatation elastic force, and can prevent the axial motion of rotating seal ring, thereby sealability is significantly improved, the water that can guarantee impeller cavity can not leak in the seat of honour, makes circuit board safe and reliable, and improve working life greatly.Because circuit board can be directly arranged between coil brace and the end cap, need not external, so compact structure, cost reduces.
