Abstract
Description
Technical Field
[0001] This application relates to the field of water conservancy engineering technology, specifically to a gate locking device. Background Technology
[0002] In the field of water conservancy engineering, gates, as a common hydraulic structure, are widely used in reservoirs, hydropower stations, and rivers for water level regulation, flood discharge, and flow management. The locking mechanism is a core component ensuring stable gate operation and water level regulation. Traditional locking methods often employ mechanical pins or hydraulic brake structures. However, mechanical pins rely on manual or mechanical force to insert into fixed holes, resulting in low positioning accuracy and difficulty in alignment, especially prone to displacement or disengagement under dynamic water flow impact. While hydraulic brakes can provide greater locking force, the system is complex, energy-intensive, and prone to locking failure due to oil leakage after prolonged use. Furthermore, existing rack and pinion locking mechanisms often suffer from insufficient impact resistance due to tooth wear or incomplete meshing, making them unsuitable for frequent opening and closing or high water level differences.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] First Embodiment
[0035] like Figure 1-4 As shown, this embodiment provides a gate locking device. The gate includes a bottom shaft 3, a gate leaf 4, a drive device 5, and an equipment base 6. The locking device includes a locking ring 1 and a locking element 2. The locking ring 1 is fixed on the bottom shaft 3, and the locking element 2 is disposed on the equipment base 6. The locking element 2 can be inserted into the gap between the locking ring 1 and the equipment base 6 to lock the gate.
[0036] Specifically, in this embodiment, the gate is a hydraulic dam, and the gate's bottom shaft 3 is rotatably supported on the equipment base 6 via a support seat. The driving device 5 is a hydraulic hoist, with one end fixed to the equipment base 6 and the other end hinged to the gate leaf 4.
[0037] Regarding locking component 2, it includes a locking push rod 21, a locking push rod seat 22, and a locking slider 23 connected in sequence. The locking push rod 21 passes through the locking push rod seat 22 and is fixedly connected to the locking slider 23. Specifically, the locking push rod seat 22 is convex, and the locking slider 23 is concave, matching the locking push rod seat 22. The locking push rod 21 controls the sliding of the locking slider 23 on the locking push rod seat 22. The convex and concave structures ensure that the sliding trajectory of the locking slider 23 does not deviate. A limit block is also provided on the side of the locking push rod seat 22 near the locking push rod 21. When the gate is locked, the direction of the water flow impact on the gate is opposite to the direction of movement of the locking slider 23 and the locking push rod 21 relative to the water flow. The limit block can ensure that the gate's locking stability is improved when it is impacted by the water flow, thus preventing locking failure.
[0038] Regarding the locking ring 1, it has several locking surfaces, with adjacent locking surfaces forming obtuse interior angles of equal angle. By rotating the bottom shaft 3, different locking surfaces can be rotated to a set locking angle. At this point, the locking surface aligns with the upper surface of the locking slider 23, forming a gap that can just accommodate the locking slider 23. Then, the locking push rod 21 is used to insert the locking slider 23 into the gap, enabling the gate to be locked at different rotation angles. When the locking surface is rotated to the set locking angle, it can be either a flat surface or an inclined surface. When the locking surface is an inclined surface, it is easier for the locking slider 23 to be inserted or removed.
[0039] The central angle of the circumscribed arc corresponding to the central axis of the adjacent locking surface can be designed according to the opening angle that the door leaf needs to maintain for a long time.
[0040] Specifically, when selecting the locking block, the locking angle of the gate can be controlled by choosing the central angle of the circumscribed arc corresponding to the central axis of different adjacent locking surfaces. In this embodiment, the central angle of the circumscribed arc corresponding to the central axis of adjacent locking surfaces is 15°, which means that locking of the gate relative to the horizontal plane at rotation angles of 90°, 75°, 60°, and 45° can be achieved. In other embodiments, the central angle of the circumscribed arc corresponding to the central axis of adjacent locking surfaces can be set to other angles. For example, when the central angle of the circumscribed arc corresponding to the central axis of adjacent locking surfaces is set to 10°, locking of the gate relative to the horizontal plane at rotation angles of 90°, 80°, 70°, and 60° can be achieved. Furthermore, setting the central angle of the circumscribed arc corresponding to the central axis of each group of adjacent locking surfaces to 10°, 15°, and 20° respectively can achieve locking of the gate relative to the horizontal plane at rotation angles of 90°, 80°, 65°, and 45°.
[0041] Furthermore, a sensor is provided on the locking ring 1. When the sensor signal confirms that the bottom shaft 3 drives the locking surface to rotate to the set locking angle, the locking slider 23 can be pushed in for insertion.
[0042] This structural design enables the gate to be locked at different angles through the insertion and cooperation of the locking ring 1 and the locking element 2, achieving multi-level water level control and increasing resistance to water flow impact. A sensor is also installed on the locking ring 1 to prevent positioning deviation. The gate locking device provided in this application has a simple structure, convenient locking, and precise positioning. The locking element 2 is also equipped with a limit block, resulting in strong resistance to water flow impact and reduced likelihood of locking failure when the gate is locked.
[0043] Second Embodiment
[0044] like Figure 5 As shown, this embodiment provides a gate locking device, which has a structure that is roughly the same as the gate locking device in the first embodiment. The difference is that the gate in this embodiment is a steel dam gate, and its driving device 5 includes a hoist and a crank arm arranged in the hoist chamber. A part of the gate bottom shaft 3 passes through the gate wall and enters the hoist chamber. In this embodiment, the locking ring 1 is set on the bottom shaft 3 in the hoist chamber, and the locking element 2 is set on the equipment base 6 in the hoist chamber. The relevant locking mechanism is not affected by water flow impact and silt erosion, and is easy to maintain.
[0045] The specific embodiments of this application have been described above. Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this application.
