Because electricity generating device floats on sea, the rotatingshaft 22 of four axle speed reduceres 21 will be carried out waterproof, seepage control seal operation and could work lastingly, and four axle speed reducer 21 be provided with mutually perpendicular four rotatingshafts 22 in four faces, the parameter of anti-storm intensity to be considered during the design of this axle.
As shown in Figure 6, axially impermeable structure is adopted to carry out waterproof, seepage control between the rotatingshaft 22 of four axle speed reduceres 21 and rotary bearing 27, the impermeable structure of described axis comprises bearing capping 28, double-layer seal rings 29 and individual layer seal ring 30, bearing capping 28 is covered on the front port of rotary bearing 27, seal ring locating flange 31 and sealing step 32 is radially extended with respectively at rotary bearing 27 inwall, sealing step 32 is higher than seal ring locating flange 31, double-layer seal rings 29 is between bearing capping 28 and seal ring locating flange 31, and be pressed between rotatingshaft 22 and rotary bearing 27, the temporary cavity 33 that seeps water is formed between seal ring locating flange 31 and sealing step 32, rotary bearing 27 wall is provided with the water seepage hole 34 being communicated with temporary cavity 33 to the outer conduit of infiltration, outer conduit is connected to the pending water tank of sewage, and regularly repair and maintenance are taken back land and are carried out oil-water separation process.Individual layer seal ring 30 is arranged on rear side of sealing step 32, is pressed between rotatingshaft 22 and rotary bearing 27.
Being provided with double-layer seal rings 29 at rotatingshaft 22 clamps between seal ring locating flange 31 and bearing capping 28, if because double-layer seal rings 29 senile abrasion has water to continue to infilter the temporary cavity 33 of infiltration, owing to seeping water, temporary cavity 33 is provided with higher sealing step 32 below, the infiltration of the temporary cavity 33 of infiltration can only be connected to conduit along the water seepage hole 34 of below, the pending water tank of sewage flow to below buoyancy tank is kept in, land process is brought back to when the electricity generating device moon protects maintenance, the double-layer seal rings 29 senile abrasion situation of rotatingshaft 22 now how much can also be judged by sewage quantity.
The waterproof, seepage control structure rotating speed reducer 23 employing is identical the same with the impermeable structure of axis of four axle speed reduceres 21, no longer describes, specifically see Fig. 7 at this.
Finally should be noted that; above embodiment is only in order to illustrate the technological scheme of the invention; but not the restriction to the invention protection domain; although done to explain to the invention with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technological scheme of the invention or equivalent replacement, and not depart from essence and the scope of the invention technological scheme.
