The air in the water tank II 76 is continuously increased, water is pressed into the square cylinder, so that the water level in the square cylinder is continuously raised, the floating ball 761 and the sliding sheet 763 are driven to rise together, and the control of the three-leaf gate is realized;
2) when the water level in the first tank 70 drops with the upstream water level, the water pressure in the lower portion of the piston 73 decreases, and the pressure difference causes the piston 73 to move downward, thereby drawing air from the second tank 76 into the sealed tank 74 through the hose 75. The air in the second water tank 76 is continuously reduced, the water level in the second water tank 76 continuously rises, so that the water level in the square cylinder continuously falls, the floating ball 761 and the sliding sheet 763 are driven to fall together, and the control of the three-leaf gate is realized.

the opening of the gate lifted or lowered by the automatic control device is maximum to the height of one sub-gate, and if the gate is lifted or lowered by the height of one sub-gate, the hoist is not lifted or lowered any more.
The manual control panel 8 is provided with three switches (as shown in fig. 6) which respectively correspond to the three gates; each switch is provided with four gears, namely ascending, descending, pause and OFF gears. Wherein the ascending gear controls the ascending of the gate; the descending gear controls the gate to descend; the pause gear controls the gate to hover to stabilize the height of the gate; the OFF position is an OFF position, that is, when the hand is directed to the OFF position, the manual control panel 8 stops operating.

when the water level is reduced to the range from the height of 3/4 to the bottom of the third gate 5 (in an initial closed state, as shown in fig. 7), when the piston 73 corresponding to the inside of the seal box 74 slides to the position ②, that is, when the slide sheet 763 slides to the position ② of the main control board 77, the third gate 5 is lifted by the height of one sub-gate by controlling the third hoist 53 (after the lifting is finished, the top of the third gate 5 contacts with the bottom of the second gate 4, the second hoist 43 stops working, wherein the first hoist cable 32 and the second hoist cable 42 are in a relaxed state), and at the moment, water flows into the water intake port through the gate bottom board 1-2, as shown in fig. 8;
finally, when the water level is lower than the water taking line, when the piston 73 corresponding to the interior of the seal box 74 slides to the position No. ①, namely the slide sheet 763 slides to the position No. ① of the main control board 77, the third gate 5 is lowered to the gate bottom plate 1-2 (the first gate 3 and the second gate 4 both descend along with the third gate 5) by controlling the third gate hoist 53, when the third gate 5 descends to the gate bottom plate 1-2, the sensor third 54 transmits a signal to the P L C processor, and the P L C processor prevents the third gate hoist 53 from continuously descending, so that the third gate 5 stops descending, and water taking is finished at the moment;
third, the gate overhaul
When the gate is overhauled, the three control buttons on the manual control panel 8 are controlled to realize the ascending, descending and pause of the gate which is correspondingly required to be overhauled. (initial state three buttons are all on OFF gear)
a) First-overhaul gate
First, the first gate button 81 is controlled to shift the first gate button 81 to the ascending gear, and when the first gate 3 ascends to a proper position, the first gate button 81 is shifted to the pause gear (as shown in fig. 11).
After the overhaul is finished, a gate button 81 is shifted to a descending gear, and after a gate 3 completely descends, the gate button 81 is shifted to an OFF gear.
b) Second gate for overhaul
Firstly, controlling a first gate button 81, shifting the first gate button 81 to a lifting gear, and shifting the first gate button 81 to a pause gear when a first gate 3 is lifted to a higher position; then, the second gate button 82 is shifted to the ascending gear position, and when the second gate 4 ascends to a proper position, the second gate button 82 is shifted to the pause gear position (as shown in fig. 12).
After the overhaul is finished, the second gate button 82 is shifted to a descending gear, and after the second gate 4 is descended, the second gate button 82 is shifted to an OFF gear; and then the first gate button 81 is shifted to a descending gear, and after the first gate 3 completely descends, the first gate button 81 is shifted to an OFF gear.
c) No. three gate for overhaul
Firstly, controlling a second gate button 82, shifting the second gate button 82 to a lifting gear, and shifting the second gate button 82 to a pause gear when a second gate 4 (a first gate 3 rises together with the second gate 4) rises to a higher position; then, the third shutter button 83 is shifted to the up shift position, and when the third shutter 5 is lifted to a proper position, the third shutter button 83 is shifted to the pause shift position (as shown in fig. 13).
After the overhaul is finished, the third gate button 83 is shifted to a descending gear, and after the third gate 5 descends, the third gate button 83 is shifted to an OFF gear; and then the second gate button 82 is shifted to a descending gear, and after the first gate 3 and the second gate 4 completely descend, the second gate button 82 is shifted to an OFF gear.
Fourth, flood-driving working condition
When a flood is required, the third gate button 83 on the manual control panel 8 is controlled to be shifted to a lifting gear, and when the third gate 5 (the first gate 3 and the second gate 4 are lifted together with the third gate 5) is lifted to a proper position, the third gate button 83 is shifted to a pause gear (as shown in fig. 14).
When the flood is finished, the third gate button 83 is shifted to a descending gear, and after the third gate 5 (the first gate 3 and the second gate 4 both descend along with the third gate 5) descends, the third gate button 83 is shifted to an OFF gear.
