2. A method of operating a tidal power System based on hydraulic engineering construction according to claim 1, wherein:

the first step is as follows: the water flow flows in the power generation cavity to drive the turbine to rotate so as to drive the power generation shaft to rotate so as to drive the generator to generate power, the garbage is accumulated on one sides of the transverse fence and the vertical fence, which are far away from the power generation shaft, when the garbage needs to be salvaged, the driving motor works to drive the driving shaft to rotate so as to drive the rope rolling wheel and the driving wheel to rotate, the rope is loosened by the rotation of the rope rolling wheel, so that the lifting spring is reset to drive the lifting plate to descend, so that the lifting block and the connecting block are descended, so that the sieve plate descends, when the sieve plate and the lifting plate descend to the lowest side, the lower pressing plate is driven to descend and compress the lower pressing spring so as to tighten the connecting rope, the limiting block is pressed back into the limiting groove by the inclined plane of the inclined plane groove and compress the limiting spring in the descending process of the lower pressing plate, at the moment, the limiting block no longer limits the rotation of the rotating shaft, the rotation of the driving wheel drives the friction wheel to rotate, thereby rotating the transmission shaft on the right side and twisting the torsion spring, because the connecting rope is pulled, thereby enabling the sliding plate to move rightwards to pull the hemp rope to enable the first limiting block on the upper side to rise and simultaneously enabling the sliding spring to reset, when the sliding plate moves to the rightmost side, the driving wheel is separated from the friction wheel and the third belt is tensioned, thereby enabling the torsion spring to reset and drive the transmission shaft on the right side to rotate, thereby enabling the driving belt pulley on the right side to drive the driving belt pulley on the left side to rotate through the second belt, thereby enabling the driving shaft on the left side to rotate, thereby enabling the driven belt pulley to drive the transmission belt pulley to rotate through the third belt, thereby enabling the rotating shaft on the left side to rotate, thereby enabling the connecting belt pulleys on the left side to drive the other four connecting belt pulleys to rotate, thereby enabling all the rotating shafts to rotate, thereby enabling the vertical fence and the horizontal fence to rotate by half a turn, the lifting plate moves to the lowest side, so that the vertical fence and the transverse fence are tensioned and cannot be close to the turbine when rotating;

the second step is that: after the vertical fence and the transverse fence rotate for half a circle, the driving motor works to drive the driving shaft to rotate reversely, so that the rope winding wheel and the driving wheel rotate reversely, the rope winding wheel is wound into the rope, the lifting plate and the sieve plate rise and compress the lifting spring, the pressing spring resets to drive the pressing plate to rise, the limiting block enters the inclined plane groove again under the action of the limiting spring, the rotating shaft is limited again, the connecting rope loosens due to the rising of the pressing plate, the first limiting block on the upper side descends to pull the hemp rope, the sliding plate moves leftwards to reset and compresses the sliding spring, the driving wheel is contacted with the friction wheel again, the floating garbage is lifted upwards due to the rising of the sieve plate, the rope winding wheel rotates to tighten the rope, the lifting block continues to move upwards and compress the lifting spring, the connecting block and the sieve plate continue to rise, a worker can open the cover to collect the garbage, the driving motor works to drive the driving shaft to rotate, and the rope winding wheel rotates to drive the lifting block to descend to reset when the rope winding wheel rotates to loosen the rope;
