[0031] The following will be described in detail in combination with the accompanying Figures 1-4 The application is further described in detail.

[0032] The embodiment of the application discloses a waterway regulation gate.

[0033] Reference Figure 1 , the waterway regulation gate comprises a rack 1, a gate 2, a parapet 3, a shunt mechanism 4, an opening and closing member 5, and a positioning member 8.

[0034] Reference Figure 1 , Figure 2The rack 1 is installed on the dam body and crosses the upper part of the gate hole on the dam body. The gate 2 is vertically slidingly installed on the rack 1. In this embodiment, a sliding groove is formed in the sidewall of the gate hole of the dam body, and the gate 2 slides in the sliding groove, thereby increasing the stability of the gate 2 during the opening and closing process. The bottom wall of the gate 2 is provided with an embedded block 7. The bottom wall of the dam body is provided with an embedded groove for the embedded block 7. The embedded block 7 is wedge-shaped and gradually decreases in width from the gate 2 to the far side of the gate 2. In this embodiment, the embedded block 7 is a rubber block.

[0035] During the process of lowering the gate 2 to close the gate hole on the dam body, the embedded block 7 first abuts against the sidewall of the embedded groove on the dam body. As the gate 2 continues to descend, the embedded block 7 enters the embedded groove and abuts against the bottom wall and the sidewall of the embedded groove under the abutting action, thereby sealing the bottom of the gate 2 from the dam body, improving the tightness between the bottom of the gate 2 and the dam body. The sidewall of the embedded groove also limits the embedded block 7, thereby limiting the closing state of the gate 2 and improving the stability of the gate 2 during closing.

[0036] Referring to Figure 2 The gate 2 is provided with a plurality of reinforcing ribs 6. In this embodiment, the reinforcing ribs 6 are steel columns, and the reinforcing ribs 6 are arranged in different inclined directions on the gate 2. The reinforcing ribs 6 reinforce the gate 2, thereby improving the structural strength of the gate 2 and reducing the possibility of deformation of the gate 2.

[0037] Referring to Figure 1 The parapet 3 is installed on the dam body and is located on the water side of the gate 2. The parapet 3 extends downward to shield the connection between the gate 2 and the opening and closing member 5. The parapet 3 blocks the water flow impacting on the upper part of the gate 2, thereby reducing the impact force of the water flow on the gate 2 and reducing the possibility of damage to the connection between the gate 2 and the opening and closing member 5 under the impact of the water flow.

[0038] Referring to Figure 2 , Figure 3 The flow distribution mechanism 4 is installed on the gate 2 and is used to distribute the water flow. The flow distribution mechanism 4 includes a plurality of supports 41 and a flow guide plate 42. The flow guide plate 42 is installed on the supports 41 and is arc-shaped. The distance between the flow guide plate 42 and the gate 2 gradually decreases from the center line of the gate 2 to both sides of the gate 2.

[0039] Before the water flow impacts on the gate 2, it first impacts on the flow guide plate 42. The arc-shaped flow guide plate 42 guides the water flow to both sides of the gate 2, thereby distributing the water flow and reducing the amount of water flow directly impacting on the gate 2, thereby reducing the impact force on the gate 2 and reducing the abrasion of the water side of the gate 2, thereby improving the problem of damage or displacement of the control gate during use.

[0040] Referring toFigure 1 、 Figure 2 The opening and closing member 5 is installed on the frame 1, and is used to drive the gate 2 to rise and fall. The opening and closing member 5 includes two hydraulic cylinders 51 which are installed on the frame 1 along the width direction of the gate 2, and the piston rods of the two hydraulic cylinders 51 are downwardly extended and are hingedly installed on both sides of the gate 2 along the width direction of the gate 2.

[0041] When the gate hole of the dam body needs to be opened, the workers control the piston rods of the hydraulic cylinders 51 to extend or retract, so as to drive the gate 2 to rise or fall, thereby realizing the opening or closing of the gate hole. The two hydraulic cylinders 51 are used to synchronously pull the two sides of the gate 2, so as to improve the stability of the gate 2 during the rising and falling process. The piston rods of the hydraulic cylinders 51 and the gate 2 are connected along the width direction of the gate 2, so that the gate 2 and the piston rods of the hydraulic cylinders 51 can have a moving space along the width direction of the gate 2. Even if the synchronization of the extension and retraction of the piston rods of the two hydraulic cylinders 51 has errors, or even if the dam body and the gate 2 are deformed, the gate 2 and the piston rods of the hydraulic cylinders 51 can still move along the width direction of the gate 2. Therefore, the possibility of damage of the connection between the gate 2 and the piston rods of the hydraulic cylinders 51 is reduced, and the normal rising and falling of the gate 2 is ensured.

[0042] Referring to Figure 1 、 Figure 4 The positioning member 8 is installed on the gate 2, and is used to position the gate 2 when the gate 2 closes the gate hole. The positioning member 8 includes a positioning seat 81 and a pre-buried seat 82. The positioning seat 81 is installed on the gate 2, and the pre-buried seat 82 is pre-buried on the dam body. When the gate 2 is lowered to close the gate hole, the positioning seat 81 is abutted to the pre-buried seat 82 and is bolted with the pre-buried seat 82.

[0043] When the gate 2 is lowered to close the gate hole, the gate 2 drives the positioning seat 81 to abut to the pre-buried seat 82. Then, the workers fix the positioning seat 81 and the pre-buried seat 82 by bolts. The pre-buried seat 82 can support the positioning seat 81, and then support the gate 2. The gate 2 is positioned in the state of closing the gate hole, and the stability of the gate 2 in closing the gate hole is improved.

[0044] The implementation principle of the channel regulation lock according to the embodiment of the application is as follows. When the hydraulic cylinder 51 drives the gate 2 to move downward to close the gate hole of the dam body, the water flow flows toward the gate 2. The parapet 3 blocks part of the water flow, reduces the impact of the water flow on the connection position between the upper part of the gate 2 and the hydraulic cylinder 51, and the flow guide plate 42 divides the water flow into two parts. The impact force of the water flow on the gate 2 is reduced, the abrasion of the water surface of the gate 2 is reduced, and the problem of damage or displacement of the regulation lock during use is improved.

[0045] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
