When the first gate plate 3 and / or the second gate plate 4 are removed or partially removed from the front / projection range of the water distribution opening 12, the water distribution opening 12 will form an unobstructed portion in the shape of a rectangular opening, and water flows into the water storage tank 2 through the unobstructed portion. The width and height of the unobstructed portion can affect the speed at which water flows into the water storage tank 2, and by controlling the distance at which the first gate plate 3 and the second gate plate 4 are moved apart, the width and height of the unobstructed portion can be controlled, thereby further controlling the speed at which water flows into the water storage tank 2.

[0046] Reference Figure 1 to Figure 3 The first gate plate 3 and the second gate plate 4 are located on the same side of the water distribution opening 12, thereby avoiding the problem that the unobstructed part cannot be rectangular due to the large distance between the first gate plate 3 and the second gate plate 4 (for example, the first gate plate 3 and the second gate plate 4 are arranged on both sides of the water distribution opening 12).

[0047] Reference Figure 1 to Figure 3 The first gate plate 3 is provided with first guide rails 31 on the upper and lower sides respectively, and the upper and lower edges of the first gate plate 3 are respectively engaged with the two first guide rails 31, so that the first gate plate 3 can slide back and forth along the length direction of the first guide rails 31, i.e., slide horizontally. The second gate plate 4 is provided with second guide rails 41 on the left and right sides respectively, and the left and right edges of the second gate plate 4 are respectively engaged with the two second guide rails 41, so that the second gate plate 4 can slide back and forth along the length direction of the second guide rails 41, i.e., slide longitudinally.

[0056] Reference Figure 4 The first sealing strip 311 is provided with a first through hole 3111, which is connected to the first receiving groove 312, and the first through hole 3111 is perpendicular to the second gate plate 4. When the first sealing strip 311 slides along the surface of the second gate plate 4, since the surface of the second gate plate 4 is not absolutely flat, the first sealing strip 311 continuously expands and contracts in the first receiving groove 312; when the first sealing strip 311 is squeezed and retracts into the first receiving groove 312, part of the water in the first receiving groove 312 is squeezed and discharged from the first through hole 3111, thereby avoiding the problem that the first sealing strip 311 cannot be retracted due to the influence of the hydraulic pressure in the first receiving groove 312.

[0057] Reference Figure 5 The second sealing strip 411 is provided with a second through hole 4111, which is connected to the second receiving groove 412, and the second through hole 4111 is perpendicular to the first gate plate 3. When the second sealing strip 411 slides along the surface of the first gate plate 3, since the surface of the first gate plate 3 is not absolutely flat, the second sealing strip 411 continuously expands and contracts in the second receiving groove 412; when the second sealing strip 411 is squeezed and retracts into the second receiving groove 412, part of the water in the second receiving groove 412 is squeezed and discharged from the second through hole 4111, thereby avoiding the problem that the second sealing strip 411 cannot be retracted due to the influence of the hydraulic pressure in the second receiving groove 412.

[0076] S2, the first gate plate 3 moves horizontally to adjust the width of the unobstructed part of the water distribution opening 12; at the same time, the second gate plate 4 moves longitudinally to adjust the height of the unobstructed part of the water distribution opening 12, thereby performing water distribution operations.

[0077] S3, the first gate plate 3 and the second gate plate 4 are moved to a state where they completely cover the water distribution opening 12, and then the sealing door body 33 extends out and presses the inclined surface 121 of the water distribution opening 12, thereby closing the water distribution opening 12.

[0078] The cross-sections of the first guide rail 31 and the second guide rail 41 are both C-shaped, the cross-sections of the edge positions of the first gate plate 3 are convex-shaped and are inserted into the first guide rail 31 and fit together, the cross-sections of the edge positions of the second gate plate 4 are convex-shaped and are inserted into the second guide rail 41 and fit together, thereby preventing the first gate plate 3 and the second gate plate 4 from falling off.

[0079] The present invention also includes an electrical cabinet, which is fixedly mounted on the upper surface of the second top plate 201 by bolts; the first gate hoist 5, the second gate hoist 6, and the oil pump 37 are respectively connected to the electrical cabinet through wires and signal lines; the electrical cabinet is connected to an external power supply and an external computer through wires and signal lines, and the computer controls the start and stop and other working states of the first gate hoist 5, the second gate hoist 6, and the oil pump 37 in the present invention through the electrical cabinet.

[0080] The present invention has a simple structure and reliable functions. It uses a first gate plate 3 that can be moved laterally and a second gate plate 4 that can be moved longitudinally to adjust the width and height of the water flow section (i.e., the weir width and the water head on the weir), thereby improving control accuracy and meeting usage requirements.

[0081] A first sealing strip 311 that can be elastically extended is inserted into the first guide rail 31, and the first sealing strip 311 abuts against the second gate plate 4, thereby avoiding the problem of water leakage in the gap between the first sealing strip 311 and the second gate plate 4; a second sealing strip 411 that can be elastically extended is inserted into the second guide rail 41, and the second sealing strip 411 abuts against the first gate plate 3, thereby avoiding the problem of water leakage in the gap between the second sealing strip 411 and the first gate plate 3, thereby further improving the control accuracy.
