TECHNICAL FIELD
[0001] The present application relates to the technical field of hydraulic engineering, in particular to a novel single-branch arm arc-shaped control discharge gate. BACKGROUND
[0002] In the field of hydraulic engineering, arc-shaped control discharge gates are widely used in dams, sluices and other facilities for regulating water flow and controlling water level to meet the needs of flood control, water diversion, irrigation, power generation and the like. At present, most commonly used arc-shaped gates adopt a double-branch arm gate structure. However, for the case of narrow orifice width, high operating water head and long-term partial opening for discharge at small opening degree, the conventional double-branch arm structure has some limitations.
[0003] The double-branch arm arc-shaped gate requires a large amount of material to manufacture the two branch arms and connecting components (including support structures), resulting in high material cost. The complex structure makes the manufacturing process cumbersome, requiring high-precision machining and assembly, which increases the production difficulty and time cost. At the same time, the connecting parts are prone to fatigue stress due to rigid contact, reducing the service life. The water seal device is a fixed rubber structure, which is prone to wear or aging over time, resulting in a decrease in sealing performance. Especially during the gate opening and closing process, the friction between the water seal and the embedded part can exacerbate the wear, requiring frequent shutdown for replacement, which affects the efficiency of the project. Therefore, we have made improvements and propose a novel single-branch arm arc-shaped control discharge gate. SUMMARY
[0004] In view of the deficiencies of the prior art, the present application provides a novel single-branch arm arc-shaped control discharge gate, which has the advantages of adapting to small orifice width, long-term partial opening for discharge at small opening degree, and side water seal vibration reduction.
[0005] To achieve the above-mentioned purposes, the present application is implemented by the following technical solutions: a novel single-branch arm arc-shaped control discharge gate, comprising a gate leaf, a water seal compensation mechanism is arranged on both sides of the gate leaf, a streamlined rib is arranged on one side surface of the gate leaf, a connecting column is connected to the side of the gate leaf away from the streamlined rib through two elastic buffer mechanisms, an H-shaped connecting seat is fixedly installed at the end of the connecting column away from the elastic buffer mechanism, an A-shaped branch arm is fixedly installed on the side of the H-shaped connecting seat away from the connecting column, and a support hinge is arranged at the end of the A-shaped branch arm away from the H-shaped connecting seat.

[0007] One side of the corrosion-resistant connecting seat is fixedly installed on one side surface of the gate leaf, and a C-shaped protective shell is fixedly installed on the side of the corrosion-resistant connecting seat away from the gate leaf.

[0011] As preferred, the elastic buffering mechanism comprises a protruding connecting seat and a rectangular fixed seat.
[0012] The one side of the protruding connecting seat is fixedly installed on the one side surface of the door leaf, and the one side of the protruding connecting seat away from the door leaf is fixedly installed with a rectangular fixed seat.
[0013] As preferred, the two ends of the rectangular fixed seat are fixedly installed with a first elliptical protruding block, the one end of each first elliptical protruding block away from the rectangular fixed seat is movably installed with an active connecting rod through a rotating shaft, and the two active connecting rods are connected through an elliptical connecting plate.
[0014] As preferred, the one end of the active connecting rod away from the first elliptical protruding block is movably installed with a second elliptical protruding block through a rotating shaft, and the one end of the second elliptical protruding block away from the active connecting rod is fixedly installed with a limiting connecting seat.
[0015] As preferred, the two ends of the one side of the rectangular fixed seat away from the protruding connecting seat are provided with a plurality of buffer main springs, the center of the one side of the rectangular fixed seat away from the protruding connecting seat is provided with a disc spring, and the one end of the buffer main spring and the disc spring away from the rectangular fixed seat is fixedly connected with an H-shaped connecting plate.
[0016] As preferred, the one side surface of the H-shaped connecting plate and the limiting connecting seat is provided with a plurality of connecting struts, the one end of the connecting struts away from the H-shaped connecting plate and the limiting connecting seat is fixedly installed with an elliptical connecting plate seat, and the one end of the elliptical connecting plate seat and the connecting column is connected.
[0017] The application provides a novel single-branch arm arc-shaped control release gate.
[0018] Firstly, the pre-tightening force of the energy storage spring can push the elastic sealing gasket and the sealing strip to automatically compensate in the direction of the embedded part when the water seal compensation mechanism is worn during use, so as to keep the sealing fit, prolong the replacement cycle of the elastic sealing gasket and the sealing strip, and effectively increase the sealing performance;
[0019] And the vibration produced by the water flow impact can be transmitted to the protruding connecting seat and the rectangular fixed seat at this time, and the buffer main spring and the disc spring can absorb the energy generated by the water flow impact and the opening and closing vibration, so as to convert the rigid contact into flexible buffering, reduce the fatigue stress of the connecting part, and prolong the service life;

At this time, the torsional spring can also convert the rigid contact into flexible buffering, reduce the fatigue stress of the connecting part, and prolong the service life.
[0021] And the streamlined ribs arranged on one side of the door leaf can guide the water flow to flow smoothly along the surface of the door leaf, reduce local turbulent flow and vortex, and reduce water flow resistance. The streamlined ribs protrude from the surface of the door leaf, can preferentially bear the water flow scouring and wear, reduce the loss of the main body steel plate of the door leaf, and prolong the overall corrosion period.
[0022] The single-branch arm reduces the material consumption of one branch arm and related connecting components, directly reduces the material cost, simplifies the manufacturing process, and does not need to process symmetrical branch arms and complex synchronous assembly structure and installation process, reduces the symmetrical positioning and calibration steps, reduces the production difficulty, shortens the period, reduces the construction error risk, and improves the engineering efficiency.
[0023] Through the optimized cross-sectional shape and size design, the single-branch arm makes the external force distribution of water pressure, opening and closing force and the like more uniform, avoids the stress concentration problem that may be caused by the structural symmetry error of the double-branch arm, reduces the fatigue damage in long-term operation, and prolongs the service life of the gate.
[0024] The single-branch arm significantly reduces the overall self-weight of the gate, reduces the load on the hoist, and improves the stability of the opening and closing process. Especially in the scene of narrow orifice width, high operating water head and long-time small opening discharge, the lightweight design is more conducive to the gate to maintain a stable posture, and at the same time, the single-branch arm reduces the shielding interference of the water flow, cooperates with the arc-shaped door leaf to make the water flow more smooth, and reduces the cavitation and erosion phenomenon in the gate slot.
