is the same, water in the front side and the rear side of the Bucherer tank 1 can enter the water bag 6 through the water inlet pipe 4, the water bags 6 on the front side and the rear side can drive the piston plates 7 to move, the water pressures on the piston plates 7 on the two sides are the same, so that the air pressures on the front side and the rear side of the piston block 11 are the same, the piston block 11 can not move, when the open channel is provided with wither branches and weeds, the wither branches and the weeds can be blocked by the salvage net frame 219, when the wither branches and the weeds are more, the front side of the Bucherer tank 1 is blocked, the water level in the front side of the Bucherer tank 1 is higher than the water level in the rear side, the water pressure on the front side of the water bag 6 is higher than the water pressure on the rear side of the water bag 6 at the moment, the front side water bag 6 can push the piston plates 7 to move to the rear side, the piston plates 7 can squeeze the air on the front side of the piston block 11, so that the air pressure on the front side of the piston block 11 is higher, the piston block 11 moves in sequence under the pushing of high pressure, the piston block 11 can squeeze the air at the rear side, the water pressure born by the water sac 6 at the rear side is smaller, the piston block is pushed by the high pressure to shrink for a section until the first conductive block 12 on the surface of the piston block 11 is contacted with the second conductive block 13 on the inner wall of the trigger box 3, the circuit of the air pump 15 is communicated, the air pump 15 continuously works, when the water in the Buchel tank 1 is just filled, the water sac 6 at the front side is firstly subjected to the water pressure, the piston block 11 is pushed to move, the first conductive block 12 is contacted with the second conductive block 13, when the water flows through the Buchel tank 1, the water sac 6 at the rear side is introduced, the air is pushed to squeeze the piston block 11, because the water depths at the front side and the rear side of the Buchel tank 1 are the same, the water pressures born by the water sac 6 at the two sides are the same, the air pressures born by the front side and the rear side of the piston block 11 are the same, the air pressure born by the first conductive block 12 and the second conductive block 13 are separated, when the air pump 15 can only work for a short time, when the air pump 15 works for a short time, a part of air discharged
