In this embodiment, when the on-off control or the water flow control is performed, the following manner is adopted.
Step1, when an automatic control system receives an instruction of opening the opening and closing plate 302 or the blocking plate 320;
If the flow required by the instruction is smaller, the driving motor 403 is started, the second gear 404 is driven by the driving motor 403 to rotate, the third gear 405 is driven by the rotation of the second gear 404, the driving shaft 406 is driven by the rotation of the third gear 405 to rotate, the first bevel 408 is driven by the rotation of the driving shaft 406 to rotate, the second bevel 409 is driven by the rotation of the first bevel 408 to rotate, the driving vertical shaft 410 is driven by the rotation of the second bevel 409, the arc 411 and the connecting bolt 415 inserted on the arc 411 are driven by the rotation of the driving vertical shaft 410, the connecting shaft 413 is further driven by the rotation of the connecting shaft 413 to rotate the lead screw 310, the moving seat 312 on the lead screw 310 is driven by the rotation of the lead screw 310 to move downwards, the moving seat 315 is driven by the movement of the moving seat 315 downwards, the first connecting plate 314 is driven by the movement of the moving seat 312 downwards, the distance between the moving block 314 and the fixed end block 318 is reduced, the moving angle between the moving plate 317 and the second connecting plate 317 is controlled by the moving window 317 and the moving window 303 is also reduced, the moving window is also driven by the movement of the moving plate 317 is controlled by the moving window 303, and the moving window is also reduced by the moving window 303, and the moving window is controlled by the moving window 303 is also reduced, and the window is moved by the moving window 320 is moved by the moving window 303. In addition, it is inevitable that when the driving shaft 406 rotates, the fourth gear 500 will also rotate, and the rotation of the fourth gear 500 will drive the rack 501 to move downward, and when the rack 501 moves downward, the movable vertical rod 502 will drive the sealing stopper 512 to move downward, and finally, a certain space exists between the upper end of the sealing stopper 512 and the opening and closing plate 302, and the water flow with rated flow will also be discharged outwards from the gap between the opening and closing plate 302 and the sealing stopper 512.
If the flow rate required by the command is large and reaches the sum of the flow rates flowing out of the gap between the rectangular window 303 and the opening and closing plate 302 and the sealing stopper 512, the motor 403 needs to be driven to fully open the closure plate 320 and the sealing stopper 512 moves to the limit low position, and after the adjustment is completed, the fitting end piece 414 needs to be ensured to be positioned on the water inlet side and the arc plate 411 is positioned on the water outlet side.
Then, the opening and closing control of the opening and closing plate 302 is performed to increase the flow rate of the water flow in unit time by opening the opening and closing plate 302, and when the posture of the opening and closing plate 302 is adjusted. Starting the opening and closing motor 201, the opening and closing motor 201 will drive the rotating shaft 210 to rotate, the rotating shaft 210 will drive the first gear 214 to rotate, the rotating of the first gear 214 will drive the arc toothed ring 217 to rotate around the lower rotating shaft to the water inlet side, and when rotating, the rectangular window 303 is opened, so that the acting force of water flow on the opening and closing plate 302 is reduced, the opening and closing plate 302 is conveniently rotated downwards, so that the opening and closing plate 302 is adjusted to be in a horizontal state from a vertical state, and then the water flow is discharged outwards through the fan-shaped plate 216 by a larger flow.
Step 2, when the automatic control system receives an instruction for closing the opening and closing plate 302 or the blocking plate 320;
If the water is transported at a smaller flow rate, since the opening and closing plate 302 is in a vertical posture in this state, when the water is closed, the driving motor 403 is started to drive each screw 310 to rotate by driving the vertical shaft 410, and finally the rectangular window 303 is plugged by the plugging plate 320, and when the water is operated, the sealing block 512 is also driven by the fourth gear 500 and the rack 501 to re-close the lower end of the opening and closing plate 302, so that the water flow interception is completed.
If the water is transported at a larger flow rate, the opening and closing plate 302 is in a horizontal posture, so that the opening and closing motor 201 needs to be started first, so that the first gear 214 drives the sector plate 216 and the opening and closing plate 302 therebetween to rotate to be in a vertical state, and the vertical barrier strip 14 acts on the inner side of the sealing jamb 220 at this time, and then the opening and closing plate 302 is supported by the vertical barrier strip 14.
