[0014] A method for adjusting a composite gate of a water distribution system comprises the following steps: S1, the sealing gate body is pulled out from the water distribution opening and retracted into the slide groove of the side wall of the first gate plate; S2, the first gate plate moves laterally to adjust the width of the unobstructed portion of the water distribution opening; and at the same time, the second gate plate moves longitudinally to adjust the height of the unobstructed portion of the water distribution opening.

[0015] In summary, the present invention has at least one of the following advantages:

[0016] (1) The present invention has a simple structure and reliable functions. It uses a first gate plate that can move laterally and a second gate plate that can move longitudinally to adjust the width and height of the water flow section (i.e., the weir width and the water head above the weir), thereby improving control accuracy and meeting usage requirements.

[0017] (2) A first sealing strip plate that can be elastically extended is inserted into the first guide rail, and the first sealing strip plate abuts against the second gate plate, thereby avoiding the problem of water leakage in the gap between the first sealing strip plate and the second gate plate; a second sealing strip plate that can be elastically extended is inserted into the second guide rail, and the second sealing strip plate abuts against the first gate plate, thereby avoiding the problem of water leakage in the gap between the second sealing strip plate and the first gate plate, thereby further improving the control accuracy.

The two side walls of the first pad are fixedly connected to the partition wall and the second guide rail respectively, and the two side walls of the second pad are fixedly connected to the partition wall and the second guide rail respectively, thereby avoiding the problem of force concentration at the intersection of the first guide rail and the second guide rail, and avoiding the problem of easy deformation of the overhead part of the second guide rail.

[0019] (4) The side wall of the first gate is provided with a sealing door body that can be extended laterally. The sealing door body can be inserted into the water distribution hole and pressed tightly with the inclined surface, thereby conveniently closing the water distribution hole and having excellent sealing performance.

[0020] (5) The first through hole is used to discharge water in the first receiving groove, thereby avoiding the problem that the first sealing strip plate is difficult to retract due to water pressure; the second through hole is used to discharge water in the second receiving groove, thereby avoiding the problem that the second sealing strip plate is difficult to retract due to water pressure.

[0021] (6) After the end of the first through hole is blocked, it is connected to the first side hole in an L-shape; the first side hole points to the water distribution hole, thereby preventing the first sealing strip from leaking on the side facing away from the water distribution hole. After the end of the second through hole is blocked, it is connected to the second side hole in an L-shape; the second side hole points to the water distribution hole, thereby preventing the first sealing strip from leaking on the side facing away from the water distribution hole.

[0022] (7) During the sliding process of the first gate plate, it vibrates with the second sealing strip plate, driving the second guide rail and the first liquid level gauge to vibrate, thereby avoiding the problem of the internal transmission structure of the first liquid level gauge being stuck due to aging or wear, and improving the reliability of liquid level detection in the water tank.

[0044] Based on the above structural features of the present application, the implementation methods of the present application are further described:

[0045] Reference Figures 1 and 2 This embodiment provides a composite gate for a water distribution system, including a partition wall 11 disposed between a water distribution channel 1 and a water reservoir 2. The partition wall 11 is provided with a water distribution opening 12. A first gate plate 3 that can move laterally and a second gate plate 4 that can move longitudinally are provided at the position of the water distribution opening 12. 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, a rectangular hole-shaped unobstructed portion is formed at the water distribution opening 12, and water flows through the unobstructed portion into the water reservoir 2. The width and height of the unobstructed portion can affect the speed at which water flows into the water reservoir 2. Therefore, by controlling the distance that 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 reservoir 2.

[0046] Reference Figures 1 to 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 distance between the first gate plate 3 and the second gate plate 4 is too large, resulting in the unblocked part being unable to present a rectangular shape (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 Figures 1 to 3 The first gate plate 3 is provided with first guide rails 31 on its upper and lower sides, and its upper and lower edges are respectively engaged with the two first guide rails 31, allowing the first gate plate 3 to slide back and forth along the length direction of the first guide rails 31, i.e., slide laterally. The second gate plate 4 is provided with second guide rails 41 on its left and right sides, and its left and right edges are respectively engaged with the two second guide rails 41, allowing the second gate plate 4 to slide back and forth along the length direction of the second guide rails 41, i.e., slide longitudinally. The first guide rails 31 are pressed and fixed to the partition wall 11 (e.g., fixedly connected by bolts), and the second guide rails 41 are pressed and fixed to the first guide rails 31 (e.g., fixedly connected by bolts).

[0048] Reference Figures 2 and 3 A first guide rail 31 and a second guide rail 41 are arranged in an L shape, and another first guide rail 31 and another second guide rail are arranged in a cross shape, so as to avoid collision between the first gate plate 3 and the second gate plate 4, and ensure that the first gate plate 3 and the second gate plate 4 can slide independently and smoothly.

[0049] Reference Figures 2 and 3The first gate plate 3 is sealed and connected to the second guide rail 41, thereby avoiding water leakage in the gap between the first gate plate 3 and the second guide rail 41, so as to further improve the control accuracy of the flow rate of the unblocked part. The second gate plate 4 is sealed and connected to the first guide rail 31, thereby avoiding water leakage in the gap between the second gate plate 4 and the first guide rail 31, so as to further improve the control accuracy of the flow rate of the unblocked part.

[0050] The first guide rail 31 is arranged horizontally, and the second guide rail 41 is arranged vertically, thereby ensuring that the first gate plate 3 slides horizontally and the second gate plate 4 moves longitudinally.

[0051] Reference Figure 2 and Figure 6 A first pad 32 and a second pad 42 for supporting the second guide rail 41 are provided between the second guide rail 41 and the partition wall 11. The first pad 32 is longitudinally arranged between the two first guide rails 31, and the second pad 42 is longitudinally arranged below the lower first guide rail 31. The first pad 32 is arranged at the end of the first guide rail 31, and the first pad 32 is fixedly connected to the partition wall 11 (for example, fixedly connected by bolts). The second pad 42 is arranged at the end of the first guide rail 31, and the second pad 42 is fixedly connected to the partition wall 11 (for example, fixedly connected by bolts). The first pad 32 is in the shape of a strip, and the length direction of the first pad 32 is arranged parallel to the second guide rail 41 located at the end of the first guide rail 31. The second pad 42 is in the shape of a strip, and the length direction of the second pad 42 is arranged parallel to the second guide rail 41 located at the end of the first guide rail 31.

[0052] Reference Figure 2 and Figure 4 A first sealing strip 311 that can be elastically extended is inserted into the first guide rail 31, and the first sealing strip 311 is vertically arranged and abutted against the second gate plate 4; the first sealing strip 311 is used to seal the gap between the first guide rail 31 and the second gate plate 4, thereby preventing water leakage between the first guide rail 31 and the second gate plate 4.

[0053] Reference Figure 2 and Figure 4 A second sealing strip 411 that can be elastically extended is inserted into the second guide rail 41. The second sealing strip 411 is vertically arranged and abuts against the first gate plate 3; the second sealing strip 411 is used to seal the gap between the second guide rail 41 and the first gate plate 3, thereby preventing water leakage between the second guide rail 41 and the first gate plate 3.

[0054] Reference Figure 4The first guide rail 31 is provided with a first receiving groove 312, which is a through-groove structure with a convex cross-section. The first sealing strip 311 is inserted into the first receiving groove 312. The first sealing strip 311 has a T-shaped cross-section. A first compression spring and a first cover plate 313 are provided in the first receiving groove 312. The ends of the first compression spring are respectively pressed against the first sealing strip 311 and the first cover plate 313. The first cover plate 313 is fixedly connected to the first guide rail 31 (for example, by bolts). The first compression spring can push the first sealing strip 311 to press against the second gate plate 4.

[0055] Reference Figure 5 The second guide rail 41 is provided with a second receiving groove 412. The second receiving groove 412 is a through-groove structure with a convex cross-section. The second sealing strip 411 is inserted into the second receiving groove 412. The second sealing strip 411 has a T-shaped cross-section. A second compression spring and a second cover plate 413 are provided in the second receiving groove 412. The ends of the second compression spring are respectively pressed against the second sealing strip 411 and the second cover plate 413. The second cover plate 413 is fixedly connected to the second guide rail 41 (for example, by bolts). The second compression spring can push the second sealing strip 411 to press against the first gate plate 3.

[0056] Reference Figure 4 The first sealing strip 311 is provided with a first through-hole 3111, which communicates with the first receiving groove 312. The first through-hole 3111 is perpendicular to the second gate plate 4. As the first sealing strip 311 slides along the surface of the second gate plate 4, the surface of the second gate plate 4 is not absolutely flat, so the first sealing strip 311 continuously expands and contracts within the first receiving groove 312. When the first sealing strip 311 is squeezed and retracts into the first receiving groove 312, some water in the first receiving groove 312 is squeezed and discharged through the first through-hole 3111, thereby preventing the first sealing strip 311 from being unable to retract due to the hydraulic pressure within the first receiving groove 312.

[0057] Reference Figure 5 The second sealing strip 411 is provided with a second through-hole 4111, which communicates with the second receiving groove 412. The second through-hole 4111 is perpendicular to the first gate plate 3. As the second sealing strip 411 slides along the surface of the first gate plate 3, the surface of the first gate plate 3 is not absolutely flat, so the second sealing strip 411 continuously expands and contracts within the second receiving groove 412. When the second sealing strip 411 is squeezed and retracts into the second receiving groove 412, some of the water in the second receiving groove 412 is squeezed and discharged through the second through-hole 4111, thereby preventing the second sealing strip 411 from being unable to retract due to the hydraulic pressure in the second receiving groove 412.

[0058] Reference Figure 4The first sealing strip 311 is provided with a first side hole, which is longitudinally arranged and connected to the first through hole 3111 in a V-shape. The length of the first side hole is parallel to the side wall of the second gate plate 4. The first side hole is located outside the first receiving groove 312. Because the end surface of the first through hole 3111 is in contact with the second gate plate 4, impurities may enter the end of the first through hole 3111 and cause blockage. This allows water in the first receiving groove 312 to be discharged through the first side hole, thereby preventing the first sealing strip 311 from being unable to retract. The first side hole points toward the water distribution opening 12, thereby preventing water leakage from the first sealing strip 311 on the side facing away from the water distribution opening 12.

[0059] Reference Figure 5 The second sealing strip 411 is provided with a second side hole, which is arranged horizontally and connects to the second through hole 4111 in a V-shape. The length of the second side hole is arranged parallel to the side wall of the first gate plate 3. The second side hole is located outside the second receiving groove 412. Because the end surface of the second through hole 4111 is in contact with the first gate plate 3, impurities may enter the end of the second through hole 4111 and cause blockage. Water in the second receiving groove 412 can be discharged through the second side hole, thereby preventing the second sealing strip 411 from being unable to retract. The second side hole points toward the water distribution opening 12, thereby preventing water leakage from the second sealing strip 411 on the side facing away from the water distribution opening 12.

[0060] Reference Figure 4 and Figure 5 Sealing terminals are respectively inserted into the end of the first through hole 3111 close to the second gate plate 4 and the end of the second through hole 4111 close to the first gate plate 3, thereby blocking the end of the first through hole 3111 close to the second gate plate 4 and the end of the second through hole 4111 close to the first gate plate 3, so that the water flowing out of the first accommodating chamber and the second accommodating chamber flows back to the vicinity of the water distribution hole 12.

[0061] Reference Figure 3 , a first liquid level gauge 410 is provided on the side wall of the second guide rail 41 that is sealed with the first gate plate 3. The side wall of the upper mounting end of the first liquid level gauge 410 is fixedly connected to the second guide rail 41 (for example, fixedly connected by bolts), and the lower movable end is suspended. During the sliding process of the first gate plate 3, vibration is generated with the second sealing strip plate 411, driving the second guide rail 41 and the first liquid level gauge 410 to vibrate, thereby avoiding the problem of the internal transmission structure of the first liquid level gauge 410 being stuck due to aging or wear, and improving the reliability of the liquid level detection in the water reservoir 2. The first liquid level gauge 410, such as an electrically controlled float level gauge, a magnetic flap level gauge, a buoy level gauge, etc., is a conventional existing technology in the industry and will not be described in detail.

[0062] Reference Figure 7The top of the water distribution channel 1 is provided with a first top plate 101, and a second liquid level gauge is vertically arranged in the water distribution channel 1. The top of the second liquid level gauge is inserted into the first top plate 101 and fixedly arranged. The second liquid level gauge is used to monitor the liquid level height in the water distribution channel 1.

[0063] Reference Figure 8 and Figure 9 The edge of the water distribution opening 12 is provided with an inclined surface 121, and the first gate plate 3 is provided with a retractable sealing door body 33. When the sealing door body 33 is extended, it can press against the inclined surface 121 to seal the water distribution opening 12. The sealing door body 33 can be extended or retracted laterally; the extension direction / retraction direction of the sealing door body 33 is perpendicular to the first gate plate 3.

[0064] Reference Figure 8 and Figure 9 A chute 30 is provided on the side wall of the first gate plate 3 near the water distribution opening 12, and a sealing door body 33 is installed in the chute 30. A linear actuator 34 is provided in the chute 30 and is arranged perpendicular to the first gate plate 3. The fixed end of the linear actuator 34 is fixedly connected to the first gate plate 3 (for example, by bolts), and the output shaft is fixedly connected to the sealing door body 33 (for example, by bolts). The linear actuator 34 can drive the sealing door body 33 to extend or retract. The linear actuator 34 is arranged between the sealing door body 33 and the first gate plate 3.

[0065] Reference Figure 8 、 Figure 9 and Figure 10 The edge of the sealing door body 33 is provided with an inner recess 331, and a sealing ring 332 is fixedly installed in the inner recess 331 (for example, fixedly connected by bolts or fixedly connected by bonding), and the sealing ring 332 is provided with a fitting surface 333 that adapts to the inclined surface 121; after the sealing door body 33 is extended and inserted into the water distribution hole 12, the fitting surface 333 can adapt to and press the inclined surface 121, thereby sealing the water distribution hole 12.

[0066] The linear actuator 34 is a hydraulic cylinder. Figure 11 and Figure 12 An internal oil pipe 35 is provided within the first gate plate 3 and is connected to and communicates with the linear actuator 34. This internal oil pipe 35 is connected to and communicates with an external oil pipe 36, which is suspended from the side wall of the partition wall 11. The top end of the external oil pipe 36 is connected to and communicates with an oil pump 37 and an oil tank 38, respectively. The oil pump 37 and oil tank 38 are bolted to the top surface of the second top plate 201. The second top plate 201 is fixed (e.g., by integral casting) to the top of the partition wall 11, serving as the roof of the water reservoir 2.

[0067] Reference Figure 11 and Figure 12A receiving channel for the built-in oil pipe 35 is provided in the first gate plate 3. An extension tube 39 is fixedly installed on the upper part of the side wall of the first gate plate 3 away from the partition wall 11 (for example, fixedly connected by welding). The extension tube 39 is connected to the receiving channel, and the built-in oil pipe 35 and / or the external oil pipe 36 are inserted into the extension tube 39; the extension tube 39 supports the external oil pipe 36, so that the external oil pipe 36 is as far away from the first guide rail 31 as possible, to avoid the external oil pipe 36 from jamming the connection position between the first guide rail 31 and the first gate plate 3.

[0068] Reference Figure 3 The first gate hoist 5 and the second gate hoist 6 are fixedly mounted on the upper surface of the second top plate 201. The first gate hoist 5 is connected to the first vertical gate rod 51, which is connected to the first horizontal gate rod 52 via a coupling 53, and the first horizontal gate rod 52 is connected to the first gate plate 3. The first gate hoist 5 drives the first vertical gate rod 51 to rotate, which in turn drives the first horizontal gate rod 52 to rotate via the coupling 53. The first horizontal gate rod 52 is a screw rod, one end of which is inserted into the first screw hole of the first gate plate 3 and connected by threads. The rotation of the first horizontal gate rod 52 can drive the first gate plate 3 to move horizontally. Two bevel gears that mesh with each other are provided in the coupling 53, and the axes of the two bevel gears are arranged perpendicular to each other; one bevel gear is coaxially arranged and fixedly connected to the first vertical gate rod 51 (for example, through an integral fixed connection or a bolted connection), and the other bevel gear is coaxially arranged and fixedly connected to the first horizontal gate rod 52 (for example, through an integral fixed connection or a bolted connection). The coupling 53 also includes a housing that fits over the two bevel gears. This housing supports and positions the two bevel gears, a technique commonly used in the industry and will not be described in detail. The housing is securely connected to the partition wall 11 via bolts. The end of the first horizontal gate rod 52, distal from the first gate plate 3, is fixed to the side wall of the partition wall 11 via a bearing and a bearing seat.

[0069] Reference Figure 3 and Figure 12 The built-in oil pipe 35 is arranged in a C shape, thereby giving way to the first horizontal gate rod 52.

[0070] Reference Figure 3 The second vertical gate rod 61 is a screw rod, and the second hoist 6 can drive the second vertical gate rod 61 to rotate; the bottom end of the second vertical gate rod 61 is inserted into the second screw hole of the second gate plate 4 and is connected through threads. When the second vertical gate rod 61 rotates, it can drive the second gate plate 4 to move longitudinally.

[0071] The first vertical gate rod 51 is inserted into the insertion hole of the first top plate 101, and the second vertical gate rod 61 is inserted into the insertion hole of the second top plate 201; the second top plate 201 is provided with a wiring hole, and the external oil pipe 36 is inserted into the wiring hole.

[0072] Reference Figure 3From the perspective shown, after the water distribution operation is completed, the first gate plate 3 moves horizontally to the left dead center and the second gate plate 4 moves vertically to the top dead center, so that both the first gate plate 3 and the second gate plate 4 cover the water distribution opening 12. The linear actuator 34 is then activated, pushing the sealing door 33 outward and pressing the inclined surface 121 to close the water distribution opening 12, thus avoiding the problem of the first gate plate 3 moving laterally having difficulty sealing the water distribution opening 12. When the linear actuator 34 extends, the first gate plate 3 is subjected to a reaction force, and the second gate plate 4 abuts the first gate plate 3 from the outside. The double-layer gate plates provide stable support and prevent the first gate plate 3 and the first guide rail 31 from falling off.

[0073] Reference Figure 11 The side wall of the sealing door body 33 near the first gate plate 3 is provided with an accommodating groove 334 for adapting the linear drive 34. The linear drive 34 is inserted into the accommodating groove 334. The accommodating groove 334 is used to reduce the total thickness of the sealing door body 33 and the first gate plate 3 (when the total thickness is too large, the first guide rail 31 is required to have a larger lateral thickness. Affected by the lever principle, the second guide rail 41 applies a greater load to the first guide rail 31, and the first guide rail 31 has a greater risk of falling off).

[0074] A method for using and adjusting a composite gate of a water distribution system, comprising the following steps:

[0075] S1. The sealing door body 33 is pulled out from the water distribution hole 12 and retracts into the sliding groove 30 on the side wall of the first gate plate 3 to open the water distribution hole 12.

[0076] S2. The first gate plate 3 moves horizontally to adjust the width of the unobstructed portion of the water distribution opening 12; at the same time, the second gate plate 4 moves longitudinally to adjust the height of the unobstructed portion 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 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 edge position cross-sections of the first gate plate 3 are convex and are inserted into the first guide rail 31 and fit together, and the edge position cross-sections of the second gate plate 4 are convex 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 the external power supply and the 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 function. It uses a first gate plate 3 that can move laterally and a second gate plate 4 that can move longitudinally to adjust the width and height of the water flow section (i.e., the weir width and the water head above the weir), thereby improving control accuracy and meeting usage requirements.

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