Description

Technical Field

[0001] The present invention relates to the technical field of dam gates, and in particular to a hydraulically driven rotary radial gate. Background Art

[0002] Water conservancy projects are vital to public well-being. For a long time, international experts have conducted extensive and in-depth research on hydraulic gates and their hoisting mechanisms, accumulating rich theoretical knowledge and experience, and developing a number of gate hoisting mechanisms with outstanding performance and high reliability. However, technological development in my country's gate hoisting mechanisms is currently relatively slow. Currently, research documents specifically focusing on span hydraulic gates and their hoisting mechanisms are scarce. With incidents of hydraulic gates both domestically and internationally, such as overload, jamming, gate damage, excessive water pressure, and entrapment by aquatic plants, dam gates are becoming increasingly vulnerable to damage. The operational safety of gates is becoming increasingly important. Summary of the Invention

[0003] The purpose of the present invention is to solve the shortcomings of the existing technology and propose a hydraulically driven rotary radial gate. To achieve the above purpose, the present invention adopts the following technical solutions:

[0004] A hydraulically driven rotary radial gate comprises a hoist disposed in a gate chamber and a radial gate disposed in the gate chamber, wherein the radial gate and the hoist are connected via a connecting rod, the radial gate being rotatably disposed in the gate chamber via a gate support arm, a rotating shaft being penetrated through the inner wall of the gate chamber, and the gate support arm being fixedly connected to the rotating shaft;

[0005] A crank arm is rotatably provided on the rotating shaft body, and the crank arm is rotatably connected to the radial gate and the gate opening machine respectively. A changing plate is also fixedly provided on the gate support arm, and the changing plate is also provided with a lower lying hole and an upper flip hole. The lower lying hole is provided on the side close to the radial gate, and the upper flip hole is provided at the end away from the radial gate. The crank arm is matched with the changing plate, and an adjustable fixed shaft is provided on the crank arm. The adjustable fixed shaft is telescopically provided on the crank arm, and the adjustable fixed shaft matches the lower lying hole and the upper flip hole.

[0006] Furthermore, the gate hoist is also equipped with a gate hoist support, and the gate hoist support is fixedly arranged on the side wall of the gate chamber through secondary casting, and the gate hoist is fixedly connected to the gate hoist support.

[0007] Furthermore, an inwardly recessed gate track is provided on the side wall of the gate chamber, and the shape of the gate track matches the arc-shaped gate.

[0008] Furthermore, a water-blocking locking convex arm and an upward-flipping locking convex arm are respectively provided on the gate support arm, and the water-blocking locking convex arm and the upward-flipping locking convex arm match the gate track.

[0009] Furthermore, blocking nets are provided at the front and rear exits of the lock chamber.

[0010] Furthermore, the lock chamber also includes a lock chamber bottom plate, and a downwardly concave arc-shaped groove is provided on the lock chamber bottom plate, and the shape of the groove matches the shape of the arc-shaped gate.

[0011] Furthermore, a bottom water-stop embedded part is embedded on the bottom plate of the gate chamber. The bottom water-stop embedded part is arranged in the arc-shaped groove on one side close to the arc gate, and an elastic I-shaped support body is arranged inside the bottom water-stop embedded part.

[0012] Furthermore, the rotating shaft is connected to a hydraulic cylinder, and the movement of the rotating shaft is controlled by the hydraulic cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention provides a crank arm between the gate hoist and the gate. The crank arm can replace the gate hoist as a new energy fulcrum, provide a buffer zone for the gate hoist, prevent the gate hoist from being directly stressed, avoid overloading of the gate hoist, and extend the service life of the gate hoist;

[0015] 2. A blocking net is also provided on the outside of the gate of the present invention to block aquatic plants and prevent them from getting entangled on the gate, thus preventing the gate from getting stuck.

[0016] 3. The present invention also provides a bottom water-stop embedded part on the gate bottom plate. The bottom water-stop embedded part is elastic and can be squeezed against the gate when the gate is closed to ensure the airtightness of the gate.

[0017] 4. The gate of the present invention adopts a rotary opening method. The force when opening and closing the gate is an up-and-down force, which greatly reduces the pressure on the gate caused by lateral water;

[0018] 5. The gate of the present invention adopts an arc gate. The arc shape can relieve the pressure caused by the continuous impact of water flow, reduce the damage of the gate, and extend the service life of the gate;

[0019] 6. The conversion lifting point of the present invention adopts the combination of hole position and crank arm. The corresponding action can be completed by moving the crank arm to different hole positions. The opening and closing equipment and the crank arm are always kept in a connected state. There is no need to use lifting mechanical facilities to separate the crank arm and the opening and closing equipment to adjust the lifting point, which greatly reduces the workload of the staff and avoids the mechanical loss caused by the separation and reconnection of the opening and closing machine and the crank arm, protects the opening and closing machine, and extends the service life of the opening and closing machine and the crank arm.

[0031] like Figures 1-8 shown.

[0032] A hydraulically driven rotary radial gate 1 comprises a gate hoist 4 arranged in a gate chamber, and also comprises a radial gate 1 arranged in the gate chamber, the radial gate 1 and the gate hoist 4 are connected by a connecting rod, the radial gate 1 is rotatably arranged in the gate chamber through a gate support arm 11, and a rotating shaft 22 is also provided on the inner wall of the gate chamber, and the gate support arm 11 is fixedly connected to the rotating shaft 22; a crank arm 21 is also rotatably provided on the rotating shaft 22, and the crank arm 21 is rotatably connected to the radial gate 1 and the gate hoist 4 respectively, a turning plate 2 is also fixedly provided on the gate support arm 11, and the turning plate 2 is also provided with a lower lying hole 23 and an upper turning hole 24, the lower lying hole 23 is arranged on a side close to the radial gate 1, and the upper turning hole 24 is arranged at an end away from the radial gate 1, the crank arm 21 is matched with the turning plate 2, and an adjustable fixed shaft 25 is provided on the crank arm 21. The retractable portion is arranged on the crank arm 21 , and the adjustable fixed shaft 25 matches the lower lying hole 23 and the upper turning hole 24 .

[0033] Furthermore, the gate hoist 4 is also equipped with a gate hoist support 41. The gate hoist support 41 is fixedly arranged on the side wall of the gate chamber through secondary casting. The gate hoist 4 and the gate hoist support 41 are fixedly connected.

[0034] Furthermore, an inwardly recessed gate track 32 is provided on the side wall of the gate chamber. The shape of the gate track 32 matches the arc gate 1. The gate track 32 can provide a running track for the gate, ensuring that the gate always remains in the established track during operation, which also reduces the water pressure to a certain extent, protects the gate, and extends the service life of the gate.

[0035] Furthermore, the gate support arm 11 is respectively provided with a water-retaining locking protrusion 111 and an upward-flipping locking protrusion 112, which match the gate track 32. The locking protrusion can be stuck on the gate track 32 when the gate reaches a predetermined position, thereby fixing the gate, reducing the pressure on the crank arm 21 and improving the service life of the equipment.

[0036] Furthermore, a blocking net 5 is provided at the front and rear exits of the lock chamber, which can intercept aquatic plants and foreign matter in the water to prevent foreign matter from entering the lock gate and related equipment.

[0037] Furthermore, the lock chamber further comprises a lock chamber bottom plate 3 , on which a downwardly concave arc-shaped groove is provided. The shape of the groove matches the shape of the arc gate 1 , and the groove can accommodate the arc gate 1 .

[0038] Furthermore, a bottom water-stop embedded part 31 is embedded on the gate chamber bottom plate 3 . The bottom water-stop embedded part 31 is arranged in the arc-shaped groove on one side close to the arc gate 1 , and an elastic I-shaped support body is arranged inside the bottom water-stop embedded part 31 .

[0039] Furthermore, the rotating shaft 22 is connected to a hydraulic cylinder, which controls the movement of the rotating shaft 22.

[0040] Furthermore, the present invention provides a crank arm 21 between the gate hoist 4 and the gate. The crank arm 21 can replace the gate hoist 4 as a new energy fulcrum, provide a buffer zone for the gate hoist 4, prevent the gate hoist 4 from being directly subjected to force, avoid overloading of the gate hoist 4, and extend the service life of the gate hoist 4.

[0041] Furthermore, a blocking net 5 is provided on the outside of the gate of the present invention to block aquatic plants, thereby preventing the aquatic plants from getting entangled on the gate and preventing the gate from getting stuck.

[0042] Furthermore, the present invention further provides a bottom water-stop embedded part 31 on the gate bottom plate. The bottom water-stop embedded part 31 is elastic and can be squeezed against the gate when the gate is closed, thereby ensuring the airtightness of the gate.

[0043] Furthermore, the gate of the present invention adopts a rotary gate opening method, and the force when opening and closing the gate is an up and down force, which greatly reduces the pressure brought to the gate by the lateral water.

[0044] Furthermore, the gate of the present invention adopts an arc-shaped gate 1. The arc shape can relieve the pressure caused by the continuous impact of water flow, reduce the damage to the gate, and extend the service life of the gate.

[0045] Furthermore, the present invention converts the lifting point by matching the hole position with the crank arm 21. The crank arm 21 can complete the corresponding action by moving to different hole positions. The opening and closing equipment and the crank arm 21 are always kept in a connected state. There is no need to use lifting mechanical facilities to separate the crank arm 21 and the opening and closing equipment to adjust the lifting point, which greatly reduces the workload of the staff and avoids the mechanical loss caused by the separation and reconnection of the opening and closing machine 4 and the crank arm 21, thereby protecting the opening and closing machine 4 and extending the service life of the opening and closing machine 4 and the crank arm 21.

[0046] Furthermore, when closing the gate, the crank arm 21 is adjusted to the position of the upper turning hole 24, and the adjustable fixed shaft 25 is screwed in so that the adjustable fixed shaft 25 is fixed in the upper turning hole 24. Then the gate hoist 4 is turned on, and the gate hoist 4 pulls the crank arm 21 backward, forcing the crank arm 21 to rotate around the upper turning hole 24, so that the crank arm 21 lifts the radial gate 1 until the water retaining locking cam 111 of the radial gate 1 is stuck in the gate track 32. At this point, the gate is closed. Its closed state can be referred to Figure 5 .

[0047] Furthermore, when the lower lying navigation is in progress, the crank arm 21 is adjusted to the position of the lower lying hole 23, and the adjustable fixed shaft 25 is screwed in so that the adjustable fixed shaft 25 is fixed in the lower lying hole 23, and then the hoist 4 is turned on, and the hoist 4 pushes the crank arm 21 forward, forcing the lower lying hole 23 to open.

[0048] The crank arm 21 rotates around the lower hole 23 so that the crank arm 21 presses the arc gate 1 into the groove of the gate chamber bottom plate 3. The lowering is completed. The lowering state can be referred to Figure 4 .

[0049] Further, when turning over for maintenance, the operation is similar to that when closing the gate, and the turning over is completed until the turning locking protrusion 112 is stuck in the gate track 32. The turning over state can be referred to Figure 6 .
