the release mechanism 300 is sleeved on the gate 400 in a vertically sliding manner, and the release mechanism 300 is positioned above the floating mechanism 200; the release mechanism 300 is linked with the positioning mechanism 700, when the release mechanism 300 moves upward along the gate 400, the positioning mechanism 700 is pushed to operate, and when the release mechanism 300 moves along the gate 400 to the stroke end, the positioning mechanism 700 releases the positioning column 500.
It can be understood that, in the implementation of the automatic adjusting device of the sluice provided by the invention, when the liquid level at the storage side of the sluice 400 is positioned below the first floating ball 201, because the first floating ball 201 is not contacted with the liquid level, under the action of the elastic supporting force of the supporting spring 503, the lifting baffle 202 is in a completely blocking state for the drainage channel 401, therefore, the continuous water storage of the water storage side of the gate 400 is not influenced at this time, and the liquid level of the water storage side of the gate 400 is kept in a reasonable state, the liquid level at the storage side of the gate 400 rises, and further, after the liquid level which continues to rise contacts the first floating ball 201, as the volume of the liquid below the liquid surface of the first floating ball 201 increases, the buoyancy of the liquid level on the first floating ball 201 is larger, at this time, the lifting baffle 202 can be enabled to move upwards, a water passing channel is formed between the bottom end of the lifting baffle 202 and the drainage channel 401 so as to reduce the water level of the water storage side of the gate 400;
certainly, when the liquid level at the water storage side of the gate 400 rises rapidly and the water passing channel formed between the lifting baffle 202 and the drainage channel 401 cannot lower the liquid level at the water storage side of the gate 400 rapidly and timely, the first floating ball 201 is submerged completely under the liquid level, and when the first floating ball 201 is completely positioned under the liquid level, the buoyancy of the first floating ball 201 is still unchanged along with the continuous rise of the liquid level, at this time, the liquid level continues to rise while the rapid drainage is still impossible, so that the release mechanism 300 moves upward, it can be understood that the upward-moving release mechanism 300 causes the positioning mechanism 700 to release the positioning column 500, the released positioning column 500 causes the supporting spring 503 to move upward, at this time, the constraint of the lifting baffle 202 by the supporting spring 503 is also released instantaneously, at this time, the lifting baffle 202 continues to move upward under the supporting action of the buoyancy of the first floating ball 201, at this time, the water passing channel continues to be amplified, to increase the rate of leakage flow.
It can be understood that, since the position of the positioning column 500 on the gate 400 is adjusted and then defined by the positioning mechanism 700, the height of the positioning column 500 on the gate 400 can be adjusted, so that the supporting stroke of the supporting spring 503 on the lifting baffle 202 can be adjusted as required, and the drainage capacity of the floating mechanism 200 can be adjusted as required.

Of course, in another embodiment of the present invention, an elastic member is not provided, and only under the action of the self gravity of the release mechanism 300, when the liquid level at the water storage side is lowered, the downward moving release mechanism 300 drives the positioning mechanism 700 to operate until the orientation of the supporting slope 702 is timely returned to the upward direction.
Further, in the embodiment of the present invention, the positioning column 500 is uniformly provided with a plurality of positioning grooves 502 matching with the positioning blocks 701.
