s20: the connector (77) is rotated, so that the first connecting cap (78) is connected with the second connecting cap (79) through the connector (77), when the hydropower station sewage passes through the intercepting net (4), the wedge-shaped grooves (631) which are arranged on the buffer plate (63) in parallel and distributed can primarily buffer water flow, and meanwhile, the water flow can be buffered again through the buffer spring (61) and the telescopic guide rod (62), the impact force of the water flow can be relieved through the deformation of the buffer spring (61), the impact force borne by the intercepting net (4) is greatly relieved, and the intercepting net (4) is stable and not easy to damage;
s30: buffer gear (6) are after the rivers buffering, can intercept silt through interception net (4), simultaneously, waterproof motor (72) drive stainless steel drive screw (73) are rotatory, stainless steel drive screw (73) can drive translation slide (74) at rotatory in-process and reciprocate the translation under the guide effect of direction slide (741), translation slide (74) are reciprocal to be translated and can be made support connecting rod (75), mounting panel (76), connector (77) and interception net (4) are also reciprocal translation thereupon, interception net (4) through reciprocal translation can shake remaining impurity on interception net (4), and then clear up interception net (4), effectively avoid interception net (4) to block up.
