It should be noted that in this embodiment, the connection lines between the buoyant members 3 are configured as flexible lines, i.e., when the buoyant members 3 connected by the connection lines move toward each other, no force is generated between them by the connection lines.

The operation of the opening and closing device for the liquid discharge pipe 10 of the liquid storage chamber 1 will be described with reference to fig. 3 a-3 e and fig. 4 a-4 e:
as shown in fig. 3a to 3e, during the process of opening the drainage pipeline 10 by the plugging member 2:
when the liquid level in the liquid storage cavity 1 is at or below the liquid level A, the plugging piece 2 plugs the opening of the liquid drainage pipeline 10 by means of the gravity of the plugging piece and the negative pressure suction force in the liquid drainage pipeline 10.
When the liquid level in the liquid storage cavity 1 is at the liquid level B, the sum of buoyancy forces borne by the lower floating piece 304 and the plugging piece 2 is smaller than the sum of gravity force and negative pressure suction force of the lower floating piece 304 and the plugging piece 2 (the stress is in a balanced state, and a connecting rope between the lower floating piece 304 and the plugging piece 2 is in a stretched straight state), and the plugging piece 2 continues to plug the opening of the liquid discharge pipeline 10.
When the liquid level in the liquid storage cavity 1 is between the liquid level B and the liquid level C, the stress of the whole formed by the lower floating piece 304 and the blocking piece 2 is in a balanced state, the upper floating piece 303 rises along with the rise of the liquid level (the connecting rope between the lower floating piece 304 and the upper floating piece 303 is in a natural bending state and does not conduct pulling force), and the blocking piece 2 continues to block the opening of the liquid discharge pipeline 10.
When the liquid level in the liquid storage cavity 1 is at the liquid level C, the buoyancy force applied to the upper floating piece 303, the lower floating piece 304 and the blocking piece 2 at this time is equal to the sum of the overall gravity and the negative pressure suction force of the upper floating piece 303, the lower floating piece 304 and the blocking piece 2 (the connecting rope between the lower floating piece 304 and the upper floating piece 303 is in a stretched straight state, and the pulling force is about to be transmitted), and the blocking piece 2 continues to block the opening of the liquid discharge pipeline 10.
When the liquid level in the liquid storage cavity 1 is at the liquid level D, the buoyancy force applied to the upper floating piece 303, the lower floating piece 304 and the blocking piece 2 is larger than the sum of the total gravity of the upper floating piece 303, the lower floating piece 304 and the blocking piece 2, the blocking piece 2 is driven by the upper floating piece 303 and the lower floating piece 304 to ascend, the blocking piece is separated from the opening of the liquid discharge pipeline 10, and the liquid discharge pipeline 10 is opened to discharge liquid.
When the plugging member 2 is separated from the opening of the drainage pipeline 10, the negative pressure suction force applied to the plugging member 2 disappears, so that the sum of the buoyancy forces applied to the upper floating member 303, the lower floating member 304 and the plugging member 2 is larger than the total gravity of the upper floating member 303, the lower floating member 304 and the plugging member 2, the lower floating member 304 and the upper floating member 303 continuously rise for a certain distance, and then the rising movement of the upper floating member 303 and the lower floating member 304 is limited due to the existence of the limiting member 5.
In the process of plugging the opening of the drainage pipeline 10 by the plugging piece 2 as shown in fig. 4 a-4 e:
when the liquid level in the liquid storage cavity 1 is at the liquid level D, the buoyancy force applied to the upper floating member 303, the lower floating member 304 and the blocking member 2 is greater than the sum of the total gravity of the upper floating member 303, the lower floating member 304 and the blocking member 2, the lower floating member 304, the upper floating member 303 and the blocking member 2 move upwards, and the lower floating member 304 is finally stabilized at the position shown in fig. 4a due to the existence of the limiting member 5.
When the liquid level in the liquid storage cavity 1 is between the liquid level B and the liquid level D, the upper floating piece 303 has no influence on the lower floating piece 304 and the plugging piece 2. Since the buoyancy force applied to the floating member 304 and the blocking member 2 is not less than the sum of the two gravity forces, the floating member 304 will be stabilized at the position shown in fig. 4b in combination with the limiting effect of the limiting member 5. It should be noted that the buoyancy force applied to the floating member 304 and the blocking member 2 is smaller than the sum of the gravity of the floating member and the minimum suction force of the drainage pipe 10, so as to ensure that the blocking member 2 can block the drainage pipe 10.
With the continuous descending of the liquid level, when the liquid level in the liquid storage cavity 1 is below the liquid level B, the upper floating member 303 is finally placed on the limiting member 5, the buoyancy force applied to the lower floating member 304 and the blocking member 2 which partially leak out of the liquid level is smaller than the gravity thereof, and at this time, the lower floating member 304 and the blocking member 2 start to gradually descend until the blocking member 2 blocks the opening of the liquid discharge pipeline 10.
