[0044] According to the above structural features of the present application, the embodiments of the present application are further described as follows:

[0045] Referring to Figures 1-2 , the present embodiment provides a composite gate of a water distribution system, which comprises a partition wall 11 arranged between a water distribution channel 1 and a reservoir 2, the partition wall 11 is provided with a water distribution opening 12, the water distribution opening 12 is provided with a first gate plate 3 capable of moving horizontally and a second gate plate 4 capable of moving vertically. When the first gate plate 3 and / or the second gate plate 4 is removed or partially removed from the front / projection range of the water distribution opening 12, the water distribution opening 12 will form a rectangular hole-shaped unshielded part, and the water flows into the reservoir 2 through the unshielded part. The width and height of the unshielded part can affect the speed of the water flowing into the reservoir 2, then controlling the distance of the first gate plate 3 and the second gate plate 4 moving away can control the width and height of the unshielded part, thereby further controlling the speed of the water flowing into the reservoir 2.

[0046] Referring to Figures 1-3 , the first gate plate 3 and the second gate plate 4 are located on the same side of the water distribution opening 12, so as to avoid the problem that the unshielded part cannot present a rectangular shape due to the excessively 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 the two sides of the water distribution opening 12).

[0047] Referring to Figures 1-3 , the first gate plate 3 is provided with a first guide rail 31 on the upper side and the lower side respectively, the upper and lower edges of the first gate plate 3 are respectively clamped with the two first guide rails 31, and the first gate plate 3 can reciprocate along the length direction of the first guide rail 31, that is, horizontally slide. The second gate plate 4 is provided with a second guide rail 41 on the left side and the right side respectively, the left and right edges of the second gate plate 4 are respectively clamped with the two second guide rails 41, and the second gate plate 4 can reciprocate along the length direction of the second guide rail 41, that is, vertically slide. The first guide rail 31 is pressed and fixed with the partition wall 11 (for example, fixed and connected by bolts), and the second guide rail 41 is pressed and fixed with the first guide rail 31 (for example, fixed and connected by bolts).

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

[0049] Referring to Figures 2-3The 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.

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.

[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 accommodating groove 312, which is a through groove structure with a convex cross section. The first sealing strip 311 is inserted into the first accommodating groove 312. The first sealing strip 311 has a T-shaped cross section. The first accommodating groove 312 is provided with a first compression spring and a first cover plate 313. The two ends of the first compression spring are respectively in pressure connection with the first sealing strip 311 and the first cover plate 313. The first cover plate 313 is fixedly connected with the first guide rail 31 (for example, by bolted connection). The first compression spring can push the first sealing strip 311 to be tightly pressed against the second shutter plate 4.

[0055] With reference to Figure 5 The second guide rail 41 is provided with a second accommodating groove 412, which is a through groove structure with a convex cross section. The second sealing strip 411 is inserted into the second accommodating groove 412. The second sealing strip 411 has a T-shaped cross section. The second accommodating groove 412 is provided with a second compression spring and a second cover plate 413. The two ends of the second compression spring are respectively in pressure connection with the second sealing strip 411 and the second cover plate 413. The second cover plate 413 is fixedly connected with the second guide rail 41 (for example, by bolted connection). The second compression spring can push the second sealing strip 411 to be tightly pressed against the first shutter plate 3.

[0056] With reference to Figure 4 The first sealing strip 311 is provided with a first through hole 3111, which is in communication with the first accommodating groove 312 and is perpendicular to the second shutter plate 4. When the first sealing strip 311 slides along the surface of the second shutter plate 4, the surface of the second shutter plate 4 is not absolutely flat, so the first sealing strip 311 continuously expands and contracts in the first accommodating groove 312. When the first sealing strip 311 is extruded to retract into the first accommodating groove 312, part of the water in the first accommodating groove 312 is extruded and discharged from the first through hole 3111, thereby avoiding the problem that the first sealing strip 311 cannot retract due to the influence of the hydraulic pressure in the first accommodating groove 312.

[0057] With reference to Figure 5 The second sealing strip 411 is provided with a second through hole 4111, which is in communication with the second accommodating groove 412 and is perpendicular to the first shutter plate 3. When the second sealing strip 411 slides along the surface of the first shutter plate 3, the surface of the first shutter plate 3 is not absolutely flat, so the second sealing strip 411 continuously expands and contracts in the second accommodating groove 412. When the second sealing strip 411 is extruded to retract into the second accommodating groove 412, part of the water in the second accommodating groove 412 is extruded and discharged from the second through hole 4111, thereby avoiding the problem that the second sealing strip 411 cannot retract due to the influence of the hydraulic pressure in the second accommodating groove 412.

[0058] With reference to Figure 4, the first sealing strip plate 311 is provided with a first side hole, the first side hole is longitudinally arranged, the first side hole is in ⊥ shape communication with the first through hole 3111; the length direction of the first side hole is arranged in parallel with the side wall of the second gate plate 4; the first side hole is located outside the first containing groove 312; because the end face of the first through hole 3111 is attached to the second gate plate 4, impurities will enter the end part of the first through hole 3111 and cause the end part of the first through hole 3111 to be blocked, then the water in the first containing groove 312 can be discharged through the first side hole, thereby avoiding the problem that the first sealing strip plate 311 cannot be retracted. The first side hole points to the water distribution hole 12, thereby avoiding water leakage of the first sealing strip plate 311 on the side facing away from the water distribution hole 12.

[0059] With reference to Figure 5 , the second sealing strip plate 411 is provided with a second side hole, the second side hole is transversely arranged, the second side hole is in ⊥ shape communication with the second through hole 4111; the length direction of the second side hole is arranged in parallel with the side wall of the first gate plate 3; the second side hole is located outside the second containing groove 412; because the end face of the second through hole 4111 is attached to the first gate plate 3, impurities will enter the end part of the second through hole 4111 and cause the end part of the second through hole 4111 to be blocked, then the water in the second containing groove 412 can be discharged through the second side hole, thereby avoiding the problem that the second sealing strip plate 411 cannot be retracted. The second side hole points to the water distribution hole 12, thereby avoiding water leakage of the second sealing strip plate 411 on the side facing away from the water distribution hole 12.

[0060] With reference to Figure 4 , and Figure 5 , the first through hole 3111 is inserted with a sealing terminal in the end part close to the second gate plate 4, and the second through hole 4111 is inserted with a sealing terminal in the end part close to the first gate plate 3, thereby blocking the end part of the first through hole 3111 close to the second gate plate 4 and the end part of the second through hole 4111 close to the first gate plate 3, so that the water flowing out of the first containing cavity and the second containing cavity flows back to the vicinity of the water distribution hole 12.

[0061] With reference to Figure 3 , the side wall of the second guide rail 41 sealingly connected with the first gate plate 3 is provided with a first liquid level meter 410, the side wall of the upper mounting end of the first liquid level meter 410 is fixedly connected with the second guide rail 41 (for example, fixedly connected by bolts), and the lower movable end is suspended. In the process of sliding of the first gate plate 3, vibration is generated between the second sealing strip plate 411, which drives the second guide rail 41 and the first liquid level meter 410 to vibrate, thereby avoiding the problem that the internal transmission structure of the first liquid level meter 410 is stuck due to aging or wear, and improving the reliability of liquid surface detection in the water storage pool 2. The first liquid level meter 410, such as an electrically controlled floating ball liquid level meter, a magnetic reed liquid level meter, a float liquid level meter, etc., is a conventional prior art in the industry, and will not be described in detail.

After the seal door body 33 is extended and inserted into the distribution hole 12, the fitting surface 333 can be adapted and tightly pressed against the inclined surface 121 to block the distribution hole 12.

[0066] The linear actuator 34 is a hydraulic cylinder. With reference to Figure 11 With reference to Figure 12 The first gate plate 3 is provided with an internal oil pipe 35 which is connected to and communicates with the linear actuator 34.

The top end of the external oil pipe 36 is connected to and communicates with an oil pump 37 and an oil tank 38 in sequence. The oil pump 37 and the oil tank 38 are fixedly installed on the upper surface of a second top plate 201 by bolts, and the second top plate 201 is fixedly installed (for example, by integral pouring) at the top end of the partition wall 11 as the roof of the water storage tank 2.

[0067] With reference to Figure 11 With reference to 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 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.

[0080] The application has simple structure and reliable function, and the width and height of the water passing section (i.e. the weir width and the water head on the weir) are adjusted by the first gate plate 3 capable of transverse movement and the second gate plate 4 capable of longitudinal movement, so that the control precision is improved and the use requirement is met.

[0081] The first guide rail 31 is inserted with the first sealing strip plate 311 capable of elastic extension, the first sealing strip plate 311 abuts against the second gate plate 4, so that the problem of water leakage between the first sealing strip plate 311 and the second gate plate 4 is avoided; the second guide rail 41 is inserted with the second sealing strip plate 411 capable of elastic extension, the second sealing strip plate 411 abuts against the first gate plate 3, so that the problem of water leakage between the second sealing strip plate 411 and the first gate plate 3 is avoided, and the control precision is further improved.
