secondly, carrying out secondary sand settling treatment: when the river water passing through the crescent sand retainer 2 passes through a river culvert outlet VI, the fine sand in the river water settles through the first-level water passing hole of the lower plate 4.3 and collides with the fine sand settling middle plate 4.2 on the upper side, the fine sand contained in the river water settles, the river water passes through the second-level water passing hole of the fine sand settling middle plate 4.2 and collides with the fine sand settling upper plate 4.1 on the upper side, the fine sand contained in the river water also settles and then flows out through the third-level water passing hole of the fine sand settling upper plate 4.1, and then flows out from the river culvert outlet VI to restore normal flow;
thirdly, after the secondary sand settling treatment, fine sand can settle below a river culvert outlet VI, a water expansion sensor 3 is arranged at the position, at the initial stage, the water-swellable rubber 3.8 swells due to water absorption, thereby pressing the rising and falling plate 3.9, and further the pressure sensor 3.2 is always triggered, and along with the continuous accumulation of the fine sand, the whole water expansion sensor 3 can be submerged by the fine sand, and the continuous increase of the thickness of the fine sand can obstruct the communication between the river water and the water-swellable rubber 3.8, and the water-swellable rubber 3.8 under the fine sand can start to shrink along with the suction effect of the underground on both sides, when the lifting plate 3.9 is contracted to a certain degree, the lifting plate is pushed upwards by the balance spring 3.4, thereby being disconnected from the pressure sensor 3.2, and then send the signal and start defeated husky hank cage 6 of both sides, defeated husky hank cage 6 drives fine sand and exports outside river course dam I to realize the second grade in river course and transfer husky desilting.
The above description is only a few of the preferred embodiments of the present invention, and any person skilled in the art may modify the above-described embodiments or modify them into equivalent ones. Therefore, any simple modifications or equivalent substitutions made in accordance with the technical solution of the present invention are within the scope of the claims of the present invention.
