Description

Technical Field

[0001] This utility model relates to the technical field of gates in water conservancy and hydropower projects, and more specifically, to a gate locking device and gate system. Background Technology

[0002] In the field of water conservancy and hydropower engineering, arc-shaped gates are widely used as working gates in spillway structures due to their excellent hydraulic characteristics. Their arc-shaped water-retaining structure can better match the free flow pattern downstream of the gate, and the shape of the gate pier has minimal interference with the water flow, making them suitable for partial flood discharge. These gates are typically driven by hydraulic hoists, relying on the contraction of hydraulic cylinders to open and maintain the opening.

[0003] However, in actual engineering projects, there are often situations where gates need to be kept open for extended periods, such as for water flow, maintenance, etc. In these cases, the hydraulic cylinders of the gate hoist are relied upon to bear the load and support the gate for a long time. However, the hydraulic hoist is prone to problems such as cylinder structure creep, sealing performance degradation, and cylinder failure when subjected to long-term loads, which can lead to risks such as the gate falling unexpectedly and pose a potential threat to the safe operation of the spillway gate system. Utility Model Content

[0004] The problem solved by this invention is how to avoid the risk of an open gate falling unexpectedly, thus ensuring the safe operation of the gate system.

[0005] To solve the above problems, this utility model provides a locking device and gate system for a gate.

[0006] In a first aspect, this utility model provides a locking device for a gate, comprising: Locking seat, the locking seat being used for fixed connection with the gate leaf of the gate system; A locking beam is arranged on the outside of the orifice channel of the spillway structure. One end of the locking beam is used to connect with the support structure, and the other end of the locking beam away from the support structure abuts against the locking seat, which is used to support the gate leaf through the locking seat.

[0007] Optionally, the locking seat includes a web, a flange, and a first pad. The web is fixedly connected to the gate leaf, the flange is fixed to the bottom end of the web, and the first pad is fixedly connected to the flange. The first pad of the locking seat abuts against the top wall of the locking beam to limit the gate leaf in the vertical direction.

[0008] Optionally, the locking seat further includes an axial limiting plate and a reinforcing structure. The axial limiting plate is fixedly connected to the flange and is set at an angle to the flange. The reinforcing structure is fixedly connected to the axial limiting plate and the flange respectively. The outer wall of the locking beam abuts against the axial limiting plate to limit the gate leaf in the horizontal direction.

[0009] Optionally, the locking beam includes a locking beam body and a second pad, the second pad being installed on the top wall of the locking beam body and fitting against the first pad.

[0010] Optionally, the locking beam further includes a locking embedded part for fixed connection with the support structure, and the end of the locking beam body away from the second pad is connected to the locking embedded part.

[0011] Optionally, the locking embedded part includes a vertical embedded plate and a first fixing member, the vertical embedded plate is fixedly connected to the first fixing member, the supporting structure includes a side wall, the first fixing member is arranged inside the side wall, and at least a portion of the vertical embedded plate is arranged outside the side wall; the locking beam body abuts against the vertical embedded plate.

[0012] Optionally, the locking device of the gate further includes an adjusting pad, at least one of the adjusting pads being installed between the locking beam body and the vertical embedded plate.

[0013] Optionally, the locking embedded part further includes a horizontal embedded plate and a second fixing member, the horizontal embedded plate being fixedly connected to the second fixing member, the support structure further includes an inspection platform, the inspection platform being fixedly connected to the side wall, the second fixing member being arranged inside the inspection platform, and at least a portion of the horizontal embedded plate being arranged above the inspection platform; the locking beam body also abuts against the horizontal embedded plate.

[0014] Optionally, the locking beam further includes a hoisting structure, which is fixedly installed between the opposite ends of the locking beam body.

[0015] Secondly, this utility model provides a gate system, including a locking device for the gate as described above, and also including a gate leaf and a hoist. The gate leaf is used to rotatably connect with the edge of the orifice channel of the spillway structure, and the hoist is connected to the gate leaf to drive the gate leaf to rotate in order to open or close the orifice channel.

[0016] The beneficial effects of the gate locking device and gate system of this utility model are: When the gate leaf needs to be locked, the locking beam is connected to the support structure so that the locking beam is supported by the support structure; and the locking beam is placed outside the flow channel of the spillway structure to avoid the locking beam obstructing the operation of the gate leaf.

[0017] When the gate opens the flow channel of the spillway structure and needs to remain open for an extended period, the gate leaf can be raised slightly above the locked opening position using the gate system's hoist. The locking beam is then positioned on the support structure in its normal locked position. The hoist drives the gate leaf down to the locked opening position, and the locking beam is adjusted so that the end furthest from the support structure abuts against the locking seat. Since the locking seat is fixedly connected to the gate leaf, the locking beam, mounted on the support structure, supports the gate leaf via the locking seat. This converts the tension of the hoist on the gate leaf into a supporting force from the support structure and the gate's locking device. The power of the hoist on the gate leaf is then removed. In other words, after the gate's locking device supports the gate leaf, the hoist does not need to be under constant load, reducing the possibility of damage. This ensures reliable locking of the gate leaf in the open position, facilitating water flow and maintenance work on the spillway structure, thus ensuring the safe operation of the gate system.

[0018] When the gate leaf needs to be unlocked, the gate leaf is first raised to a certain height by the hoist, and then the locking beam is removed from the outside of the orifice flow channel to complete the unlocking of the gate leaf. Attached Figure Description

[0024] To address the problems existing in the aforementioned related technologies, this embodiment provides a gate locking device and gate system.

[0025] like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention provides a locking device for a gate, comprising: Locking seat 4, which is used to be fixedly connected to the gate leaf 5 of the gate system; Locking beam 1 is arranged on the outside of the orifice channel of the spillway structure. One end of the locking beam 1 is used to connect with the support structure 7, and the other end of the locking beam 1 away from the support structure 7 abuts against the locking seat 4, and is used to support the gate leaf 5 through the locking seat 4.

[0026] Specifically, the gate leaf 5 can be understood as the movable water-retaining structure part of the gate in the relevant technology.

[0027] The locking beam 1 can adopt a box-type cantilever beam structure to ensure sufficient rigidity and reduce deformation under the pressure of the gate leaf 5. The locking beam 1 can be arranged horizontally, vertically, or inclinedly on the outside of the orifice channel of the spillway structure; where inclined arrangement means that the extension direction of the locking beam 1 is perpendicular to the direction of the gate leaf 5. Figure 2 The Z-axis and Y-axis in the coordinate system are set at an angle.

[0028] One end of the locking beam 1 is used to connect with the support structure 7. Here, "connection" can be understood as the locking beam 1 and the support structure 7 being fixedly connected by fasteners such as anchor bolts, or one end of the locking beam 1 directly or indirectly abutting against the support structure 7 through other structures. The lower end of the two ends of the locking beam 1 is connected to the support structure 7.

[0029] The support structure 7 refers to a fixed structure arranged on the outside of the orifice channel of the spillway structure and capable of supporting the locking beam 1. This fixed structure can be fixedly connected to the outer area of ​​the orifice channel of the spillway structure.

[0030] The locking seat 4 supports the gate leaf 5. Here, "support" can be understood as the locking seat 4 providing static support and lifting for the gate leaf 5.

[0031] In this embodiment, when the gate leaf 5 needs to be locked, the locking beam 1 is connected to the support structure 7 so that the locking beam 1 is supported by the support structure 7; and the locking beam 1 is placed outside the flow channel of the spillway structure to avoid the locking beam 1 from obstructing the operation of the gate leaf 5.

[0032] When the gate opens the flow channel of the spillway structure and needs to remain open for an extended period, the gate leaf 5 can be raised slightly above the locked opening position using the gate hoist 6. The locking beam 1 is then positioned on the support structure 7 in its normal locked position. The hoist 6 drives the gate leaf 5 down to the locked opening position. The locking beam 1 is adjusted so that the end of the locking beam 1 furthest from the support structure 7 abuts against the locking seat 4. Since the locking seat 4 is fixedly connected to the gate leaf 5 of the gate system, the gate is controlled via the locking beam 1 installed on the support structure 7 and the locking seat 4. The gate leaf 5 is supported, so that the tension of the hoist 6 on the gate leaf 5 is converted into the supporting force of the support structure 7 and the locking device of the gate on the gate leaf 5. The power of the hoist 6 on the gate leaf 5 is removed. In other words, after the locking device of the gate supports the gate leaf 5, the hoist 6 does not need to be under load for a long time, reducing the possibility of damage to the hoist 6. This achieves reliable locking of the gate leaf 5 in the open state, so as to facilitate the passage of water or the maintenance work of maintenance personnel on the spillway structure. Accordingly, it ensures the safe operation of the gate system.

[0033] When the gate leaf 5 needs to be unlocked, the gate leaf 5 is first raised to a certain height by the hoist 6, and then the locking beam 1 is removed from the outside of the orifice flow channel to complete the unlocking of the gate leaf 5.

[0034] Optionally, such as Figure 7 and Figure 8 As shown, the locking seat 4 includes a web plate 41, a flange 42, and a first pad 43. The web plate 41 is fixedly connected to the gate leaf 5. The flange 42 is fixed to the bottom end of the web plate 41. The first pad 43 is fixedly connected to the flange 42. The first pad 43 of the locking seat 4 abuts against the top wall of the locking beam 1 and is used to limit the gate leaf 5 in the vertical direction.

[0035] Specifically, the web plate 41 can be fixed to the side beam of the gate leaf 5 by welding or bolt fasteners.

[0036] The bottom ends of the flange 42 and the web 41 can be fixedly connected by welding. The first pad 43 can be fixedly connected to the bottom of the flange 42 by welding, so as to adjust the bearing surface of the locking seat 4 against the locking beam 1 to a horizontal state through the first pad 43.

[0037] The top wall of the locking beam 1 is connected to the first pad 43 by abutting.

[0038] In this optional embodiment, since the web plate 41 is fixedly connected to the gate leaf 5, the flange 42 is fixed to the bottom end of the web plate 41, and the first pad 43 is fixedly connected to the flange 42, the first pad 43 is fixedly connected to the web plate 41 through the flange 42, thereby realizing the fixed connection between the locking seat 4 and the gate leaf 5. Since the first pad 43 of the locking seat 4 abuts against the top wall of the locking beam 1, the first pad 43 adjusts the bearing surface of the locking seat 4 on the locking beam 1 to a horizontal state, based on the locking beam 1 provided on the support structure 7 supporting the gate leaf 5 through the locking seat 4. This not only improves the support stability of the gate leaf 5, but also allows the first pad 43 of the locking seat 4 to limit the gate leaf 5 in the vertical direction.

[0039] Optionally, combined Figure 8 As shown, the locking seat 4 also includes an axial limiting plate 44 and a reinforcing structure 45. The axial limiting plate 44 is fixedly connected to the flange 42, and the axial limiting plate 44 and the flange 42 are arranged at an angle. The reinforcing structure 45 is fixedly connected to the axial limiting plate 44 and the flange 42 respectively. The outer wall of the locking beam 1 abuts against the axial limiting plate 44 to limit the gate leaf 5 in the horizontal direction.

[0040] Specifically, the axial limiting plate 44 can be the side beam web plate 41 of the gate leaf 5, or it can be set separately as needed and fixedly connected to the flange 42.

[0041] The flange 42 can be parallel to the horizontal plane; the axial limiting plate 44 can be parallel to the vertical plane. The axial limiting plate 44 and the flange 42 are arranged at an angle, for example, perpendicularly. The axial limiting plate 44 and the flange 42 can be fixedly connected by welding.

[0042] The reinforcing structure 45 may employ reinforcing ribs. The reinforcing structure 45 is fixedly connected to the axial limiting plate 44 and the flange 42 respectively, so as to further increase the connection area between the axial limiting plate 44 and the flange 42, improve the local strength of the axial limiting plate 44, and enhance the connection stability between the axial limiting plate 44 and the flange 42.

[0043] In this optional embodiment, the first pad 43 of the locking seat 4 is supported on the locking beam 1, which can limit the gate leaf 5 in the vertical direction; the outer wall of the locking beam 1 is pressed against the axial limiting plate 44, which can limit the gate leaf 5 in the horizontal direction, so that the first pad 43 of the locking seat 4 and the axial limiting plate 44 cooperate with each other to securely and reliably lock the gate leaf 5 at the support structure 7, effectively preventing the gate leaf 5 from falling when it is in the open state.

[0044] Optionally, combined Figure 6 and Figure 8 As shown, the locking beam 1 includes a locking beam body 11 and a second pad 13. The second pad 13 is installed on the top wall of the locking beam body 11 and is in contact with the first pad 43.

[0045] Specifically, when the outer wall of the locking beam 1 abuts against the first pad 43 of the locking seat 4, the second pad 13 can be installed between the locking beam body 11 and the first pad 43. The second pad 13 and the top wall of the locking beam body 11 can be fitted together, and the two do not need to be connected by fasteners.

[0046] The areas of the second pad 13 and the first pad 43 can be the same or different.

[0047] In this optional embodiment, the second pad 13 of the locking beam 1 is installed between the locking beam body 11 and the first pad 43 of the locking seat 4, so that the two opposing surfaces of the locking beam body 11 and the flange 42 can be adjusted to a horizontal state by means of the second pad 13 and the first pad 43, thereby further improving the support stability of the gate leaf 5.

[0048] Optionally, combined Figure 1 and Figure 2 As shown, the locking beam 1 also includes a locking embedded part 3, which is used to fix the locking embedded part 3 to the support structure 7. The end of the locking beam body 11 away from the second pad 13 is connected to the locking embedded part 3.

[0049] Specifically, the end of the locking beam body 11 away from the second pad 13, such as the bottom end, can be connected to the locking embedded part 3. Here, "connection" can mean that the locking beam body 11 abuts against the locking embedded part 3, or that the locking beam body 11 and the locking embedded part 3 are fixedly connected by other structures.

[0050] In this optional embodiment, since the locking embedded part 3 is fixedly connected to the support structure 7, the end of the locking beam body 11 away from the second pad 13 is connected to the locking embedded part 3. Thus, the support strength and flatness of the support structure 7 on the locking beam body 11 can be increased by the locking embedded part 3, thereby improving the support stability of the support structure 7 and the locking embedded part 3 on the locking beam 1.

[0051] Optionally, combined Figure 2 As shown, the locking embedded part 3 includes a vertical embedded plate 33 and a first fixing member 34. The vertical embedded plate 33 is fixedly connected to the first fixing member 34. The supporting structure 7 includes a side wall 71. The first fixing member 34 is arranged inside the side wall 71. At least a portion of the vertical embedded plate 33 is arranged outside the side wall 71. The locking beam body 11 abuts against the vertical embedded plate 33.

[0052] Specifically, the side wall 71 of the supporting structure 7 can be located outside the orifice of the drainage structure, and the side wall 71 is arranged vertically.

[0053] Multiple first fasteners 34 are provided on the surface of the vertical embedded plate 33. The first fasteners 34 can adopt an anchor bar structure. One end of the first fastener 34 is fixedly connected to the vertical embedded plate 33 by welding. The end of the first fastener 34 away from the vertical embedded plate 33 is arranged in the side wall 71. The end of the first fastener 34 away from the vertical embedded plate 33 can have a bent part, thereby increasing the anchoring force between the first fastener 34 and the side wall 71.

[0054] At least a portion of the vertical embedded plate 33 is disposed on the outer side of the side wall 71. This can be understood as a portion of the vertical embedded plate 33 being disposed on the outer side of the side wall 71, and another portion being disposed inside the side wall 71; or, the entire vertical embedded plate 33 is disposed on the outer side of the side wall 71. The vertical embedded plate 33 may be a vertically arranged plate-like structure.

[0055] In this optional embodiment, since the first fixing member 34 is arranged inside the side wall 71, the vertical embedded plate 33 is fixedly connected to the first fixing member 34, so that the vertical embedded plate 33 is fixedly installed on the side wall 71 by the first fixing member 34. The locking beam body 11 abuts against the vertical embedded plate 33, so that the vertical embedded plate 33 fixed to the side wall 71 abuts against the locking beam body 11, providing a relatively flat and pressure-resistant mounting surface in the horizontal direction for the locking beam body 11, so as to ensure the installation accuracy of the locking beam 1.

[0056] Optionally, combined Figure 2 As shown, the locking device of the gate also includes an adjusting pad 2, and at least one adjusting pad 2 is installed between the locking beam body 11 and the vertical embedded plate 33.

[0057] Specifically, the adjusting shim 2 can be a vertically arranged plate-like structure. At least one adjusting shim 2 is required. The thickness and number of adjusting shims 2 can be determined based on the on-site installation conditions.

[0058] In this optional embodiment, the adjusting shim 2 is disposed between the rear end of the locking beam 1 and the vertical embedded plate 33 installed on the side wall 71, and is used to adjust the installation and manufacturing errors in the assembly of the gate leaf 5 and the locking beam 1, so that the locking beam 1 can lock the opening position of the gate leaf 5 tightly and reliably.

[0059] Optionally, combined Figures 2 to 4As shown, the locking embedded part 3 further includes a horizontal embedded plate 31 and a second fixing member 32. The horizontal embedded plate 31 is fixedly connected to the second fixing member 32. The support structure 7 further includes a maintenance platform 72. The maintenance platform 72 is fixedly connected to the side wall 71. The second fixing member 32 is arranged inside the maintenance platform 72. At least a portion of the horizontal embedded plate 31 is arranged above the maintenance platform 72. The locking beam body 11 also abuts against the horizontal embedded plate 31.

[0060] Specifically, the maintenance platform 72 of the support structure 7 can be located outside the orifice flow channel of the spillway structure, and the maintenance platform 72 is horizontally arranged and fixedly connected to the side wall 71. The maintenance platform 72 and the side wall 71 can be constructed as an integral support structure 7.

[0061] Multiple second fasteners 32 are provided on the bottom surface of the horizontal embedded plate 31. The second fasteners 32 can be anchor bars. One end of the second fastener 32 is fixedly connected to the horizontal embedded plate 31 by welding. The end of the second fastener 32 away from the horizontal embedded plate 31 (e.g., the bottom end) is arranged in the maintenance platform 72. The end of the second fastener 32 away from the horizontal embedded plate 31 may have a bent portion (see...). Figure 3 As shown in the figure, this can increase the anchoring force between the second fastener 32 and the maintenance platform 72.

[0062] At least a portion of the horizontal embedded plate 31 is arranged above the maintenance platform 72. This can be understood as a portion of the horizontal embedded plate 31 being located outside the maintenance platform 72, and another portion being located inside the maintenance platform 72; or, the entire horizontal embedded plate 31 being located outside the maintenance platform 72. The horizontal embedded plate 31 may be a horizontally arranged plate structure.

[0063] In this optional embodiment, since the second fixing member 32 is arranged inside the maintenance platform 72, the horizontal embedded plate 31 is fixedly connected to the second fixing member 32, so that the horizontal embedded plate 31 is fixedly installed on the maintenance platform 72 by the second fixing member 32. The locking beam body 11 abuts against the horizontal embedded plate 31, so that the horizontal embedded plate 31 fixed to the maintenance platform 72 abuts against the locking beam body 11, providing a relatively flat and pressure-resistant mounting surface in the vertical direction for the locking beam body 11, further ensuring the installation accuracy of the locking beam 1, and correspondingly improving the support stability of the locking beam 1 on the gate leaf 5.

[0064] Optionally, combined Figure 6 As shown, the locking beam 1 also includes a hoisting structure 12, which is fixedly installed between the two opposite ends of the locking beam body 11.

[0065] Specifically, the hoisting structure 12 can adopt a lifting ring structure.

[0066] At least one hoisting structure 12 may be provided in the upper region between the two opposite ends of the extending direction of the locking beam body 11.

[0067] The hoisting structure 12 and the locking beam body 11 can be fixedly connected by welding.

[0068] In this optional embodiment, the hoisting structure 12 can be fixedly installed on the top of the locking beam body 11 by welding, so as to facilitate the lifting equipment, such as a crane, to move the locking beam 1.

[0069] According to the opening degree required for the flow channel of the spillway structure to open the gate leaf 5, the locking seat 4 can be fixedly installed at different heights of the gate leaf 5. For example, multiple mounting holes can be provided on the edge of the gate leaf 5. The multiple mounting holes can be arranged vertically or along the arc edge of the gate leaf 5. The connection position between the gate leaf 5 and the locking seat 4 can be changed by bolts and fasteners passing through the mounting holes at different positions of the gate leaf 5 and the web plate 41 of the locking seat 4. Accordingly, the locking seat 4 can be fixedly installed at different heights of the gate leaf 5.

[0070] This utility model provides a gate system, including a gate locking device as described in the above embodiment, and also includes a gate leaf 5 and a hoisting machine 6. The gate leaf 5 is used to rotatably connect with the edge of the orifice flow channel of the spillway structure. The hoisting machine 6 is connected to the gate leaf 5 and is used to drive the gate leaf 5 to rotate, so as to open or close the orifice flow channel.

[0071] The gate system in this embodiment also includes a gate leaf 5, which can be an arc-shaped gate structure. Other gate structures of the same shape are also acceptable, and are not specifically limited here. The hoist 6 can be a hydraulic hoist. When the hydraulic piston rod of the hoist 6 is extended, the gate leaf 5 is in a closed orifice flow channel state; when the hydraulic piston rod of the hoist 6 is retracted, the gate leaf 5 is in an open orifice flow channel state.

[0072] The upper end of the gate leaf 5 can be rotatably connected to the edge of the orifice channel of the spillway structure via a pin structure. The fixed end (e.g., cylinder) of the hoist 6 can be installed above the orifice channel. The telescopic end (e.g., piston rod) of the hoist 6 is connected to the edge of the gate leaf 5 to drive the gate leaf 5 to rotate, thereby opening or closing the orifice channel.

[0073] The gate system of this embodiment has the same beneficial effects over the prior art as the gate locking device described above, and will not be repeated here.

[0074] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
