Working principle: when the gate is installed and lowered and the gate deviates from the embedded part to be placed in the underwater groove, firstly, the aligning quick-connection device is placed in the underwater groove, then the gate is lowered, if the offset distance of the gate is within the range of the aligning mechanism 30, the gate is quickly lowered, the bottom of the gate is firstly contacted with the inner surface of the second connecting plate 31, slowly lowered after contact, gradually moved to the T-shaped groove 11 along the inclined plane formed by the second connecting plate 31 when the gate slowly lowered, after the gate moves to the T-shaped groove 11 for a certain distance, the bottom surface of the gate is contacted with the top plate 21 of the buffer mechanism 20, when the gate continues to be lowered, the top plate 21 moves downwards along with the gate, and when the top plate 21 moves downwards along with the gate, the gate is aligned with the underwater groove, the top plate 21 moves downwards to push the first connecting rod 23, the first connecting rod 23 is pushed to compress the second spring 29, the second spring 29 is compressed to buffer the top plate 21, the first telescopic rods 28 on the two sides of the top plate 21 are contracted when the top plate 21 starts to move downwards, the moving ends of the first telescopic rods 28 are contracted to compress air at the bottoms of the moving ends, so that the first telescopic rods 28 play a certain role in buffering while being stably supported, the two sides of the top plate 21 push the first connecting plate 13 to enable the first connecting plate 13 to be gradually and inwards aligned along with the second connecting plate 31 when the top plate 21 starts to move downwards, the alignment mechanisms 30 on the two sides are completely aligned after the top plate 21 is contacted with the step surface of the T-shaped groove 11, the gate is completely abutted with the water bottom groove at the moment, and therefore, the gate is not worry of shifting when being placed down after that, since the first connecting plate 13 is connected with the second connecting plate 31 through the first sliding groove 13a and the first sliding block 32, therefore, after the gate is completely abutted, the second connecting plate 31 can be integrally taken out, and the second connecting plate can be recycled, thereby being beneficial to saving the cost.

If the offset distance between the gate and the water bottom tank exceeds the initial correction range of the alignment mechanism 30, the dual-shaft motor 3413 is started first, so that the screw 3419 starts to rotate, and the expansion mechanism 342 is lifted up through the threaded fit of the hex nut 34217 and the screw, when the expansion assembly moves out of the notch IV 33, the spring III 3426 pulls the expansion plate 3428 to rotate, the expansion plate 3428 rotates inwards while the connecting rod II 34210 and the telescopic rod II 34214 rotate together, when the expansion plate 3428 rotates at a certain angle, the connecting rod II 34210 is blocked by the stop 3422, so that the expansion plate 3428 does not rotate any more, the expansion plate 3428 is in a vertical state, the height of the expansion mechanism 342 is controlled by the dual-shaft motor 3413 according to the offset distance, the gate is quickly lowered down after the gate is in the correction range regulated by the expansion mechanism 342, the gate bottom end passes through the expansion plate 3428, the gate is slowly lowered down, the dual-shaft motor 343 is controlled to enable the expansion plate 3428 to start to rotate inwards, when the gate opening is not in contact with the two end faces 31, and the expansion plate 31 is gradually retracted after the opening of the expansion plate is in contact with the two end faces of the two connecting plates 31, and the expansion plate 31 is gradually retracted after the opening is in the same speed as the expansion plate 31.
