Description

Technical Field

[0001] This utility model relates to the field of tide gate technology, and in particular to a large-span shore-controlled floating herringbone tide gate. Background Technology

[0002] To protect the lives and property of people in coastal cities, methods such as constructing flood control walls or tide gates can be used. However, in practice, due to the large investment required for flood control walls and their potential to damage the unique waterfront environment of coastal cities, the vast majority of projects utilize tide gates to resist storm surges. Commonly used large-span tide gates (single span 100m to 200m) typically have double-opening fan-shaped gates. However, for ultra-large span rivers of 400m to 500m, regardless of the type of tide gate used, gate piers must be installed in the water, thus causing significant negative impacts on navigation and the original river's hydrology and course during the construction, operation, and maintenance phases. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides an ultra-large span shore-controlled floating miter gate tide gate, specifically employing the following technical solution:

[0004] The ultra-large span shore-controlled floating miter gate of this utility model includes a gate body with an overflow hole. A rotating gate is installed in the overflow hole. The rotating gate has a closed state that closes the overflow hole and an open state that allows water to flow through. The head of the gate body is located on the outer side of the river channel, and the tail of the gate body is connected to a balancing opening and closing device, which is installed on both banks on the inner side of the river channel.

[0005] The aforementioned gate body serves as both a water-blocking and force-transfer structure, transferring the water load generated by the storm surge head difference to the foundation structure on the shore. Furthermore, a rotating gate is installed within the gate body's flow passage. When the gate body is opened and closed, the rotating gate remains open, reducing water resistance and preventing vertical or lateral tilting during operation. This "gate-within-a-gate" design solves the problems of excessive water backlog and excessive opening / closing force during the opening and closing of the floating miter gate, ensuring the vertical stability of the gate body and contributing to the overall safety of the storm surge gate.

[0006] Preferably, the gate body is a hollow metal float structure, the flow passage is an elongated hole along the length of the gate body, and multiple rotary gates are arranged side by side in each flow passage, with the rotating shaft of the rotary gate arranged vertically. This structure of multiple rotary gates arranged side by side improves construction convenience, and the vertical arrangement of the rotating shaft helps to further reduce water resistance.

[0007] Preferably, the top wall of the flow passage is provided with a rotary drive mechanism connected to the rotating shaft of the rotary gate.

[0008] Preferably, the gate body and the gate bottom plate are spaced apart, and the bottom of the gate body is provided with an inflatable water-stop bag and a telescopic support rod.

[0009] A flow passage is reserved at the bottom of the gate body to solve problems such as water backflow and gate jamming caused by siltation during the opening and closing of the floating miter gate. When the floating miter gate is completely closed, a water-stop bag is used to seal the bottom flow passage to prevent flow. At this time, the support rod extends and supports the bottom plate of the gate, which plays the role of supporting the gate body.

[0010] Preferably, the gate body has a streamlined structure that is narrow at both ends and wide in the middle. Multiple water-stop bags are arranged at intervals along the width direction of the gate body, and each water-stop bag extends along the length direction of the gate body and is set in the same shape as the outline of the gate body. The support rod is arranged between adjacent water-stop bags.

[0011] Preferably, the gate body is provided with anti-collision buffer layers on both the water-facing and back-facing surfaces.

[0012] Preferably, an alignment guide mechanism is provided at the head joint of the gate body. The alignment guide mechanism includes a V-shaped guide groove provided on the top of one side of the gate body and a roller provided on the top of the other side of the gate body. The V-shaped guide groove is horizontally arranged and its opening faces the other side of the gate body. The roller is correspondingly adapted to the V-shaped guide groove.

[0013] When the floating gate is about to close, one of the gates, under the action of the roller, makes a small-amplitude deceleration pendulum motion along the V-shaped guide groove, which can quickly lock to the corner of the V-shaped groove, ensuring that both gates close accurately.

[0014] Preferably, the balancing opening and closing device includes a balancing opening and closing plate, which is mounted on the resisting pier of the concrete structure via a ball joint. The front end of the balancing opening and closing plate is connected to the gate body, and the rear end of the balancing opening and closing plate is adapted to the C-shaped groove on the resisting pier. A gear and rack transmission mechanism is provided between the C-shaped groove and the balancing opening and closing plate. A slider is provided at the top of the balancing opening and closing plate, and an elastic support wheel is provided at the bottom. Both the slider and the elastic support wheel are connected to the C-shaped groove.

[0015] The C-groove of the aforementioned balancing opening and closing device guides the movement of the balancing opening and closing plate, while the ball hinge serves as the rotation center for both the balancing opening and closing plate and the gate body, ensuring the gate body can rotate flexibly. The ball hinge primarily bears the vertical load of the gate and the horizontal load during the opening and closing process.

[0016] Preferably, the gate body is located below the balance opening and closing plate, the tail of the gate body is provided with a support pad, and the side wall of the resistance block is provided with a pillow pad corresponding to the position of the support pad.

[0017] The support pads are the hinge components that form the three-hinged arch structure of the floating V-gate. The support pads are placed on the gate shaft column and the diagonal column of the gate, and the pads are placed on the resisting piers. Both adopt a continuous support pad structure. When the gate is closed, the water pressure (horizontal load) acting on the gate leaf is transmitted to the resisting piers only through the support pads.

[0018] Preferably, the front side of the resisting pier is provided with a niche extending outward to the riverside of the river channel, the niche being adapted to the gate body, and the two niches being parallel to each other.

[0019] This utility model provides an ultra-large span shore-controlled floating miter gate tide barrier, mainly composed of the gate body and a balanced opening and closing device. During normal navigation, the gate body is positioned on both sides of the river channel, not affecting normal passage. When storm surges occur, it can quickly close, forming a three-hinged arch structure to block the tide. It features structural stability, flexible opening and closing, safe operation, and convenient maintenance. Furthermore, its structural design, manufacturing, transportation, installation, and maintenance do not affect navigation or the original river's hydrology and morphology, thus minimizing the impact on the original river channel.

[0020] Compared with the prior art, the advantages of this utility model are as follows:

[0021] 1) It has a wide range of applications and can be used for tidal barriers in river channels with normal spans (50m to 100m per span), large spans (100m to 200m per span), and super large spans (400m to 500m per span).

[0022] 2) The rotation center of the gate body is set on both sides of the river channel. When in the water, no gate pier structure or complex mechanical and electrical equipment is required, so it does not affect normal navigation. When a storm surge comes, the gate body closes under the action of the opening force and forms a stable three-hinged arch structure. The water load generated by the storm surge is transferred to the foundation on the shore through the gate leaf structure, thereby stably resisting the impact of storm surge on coastal megacities and ensuring the safety of people's lives and property in coastal areas.

[0023] 3) This utility model adopts a rotating gate installed on the gate body, i.e., a "gate within a gate" design, which makes up for the shortcomings of conventional miter gate structures when applied to ultra-large span rivers, where the gate is prone to vertical and lateral tilting during opening and closing due to the small stroke of the opening and closing equipment; secondly, a flow passage is reserved at the bottom of the gate body, which can solve the problems of water backlog and gate jamming caused by siltation during the opening and closing of the floating miter gate, further maintaining the stability of the gate opening and closing; thirdly, by setting up an alignment guide mechanism, it is ensured that the two gates close accurately.

[0024] 4) The tide gate described in this utility model is routinely inspected and maintained in the niches on both banks. If major repairs are required, the gate body can be towed to a shipyard by tugboat or repaired directly by wading. Therefore, it will not have a significant impact on shipping during operation and maintenance.

[0025] 5) The tide gate described in this utility model does not have gate piers in the water and does not increase the riverbed elevation. Moreover, the caisson method is used for construction during the construction period. The prefabricated caisson is directly sunk into the water and construction can be carried out without interrupting traffic. Therefore, it will not have a significant impact on shipping during the construction phase.

[0026] 6) To address the design issues of reasonable gate type and structure for ultra-large span tide gates, the design follows the principles of structural safety, advanced technology, flexible opening and closing, and convenient maintenance. The spatial system method is directly adopted for its structural design, which improves the design quality and efficiency of ultra-large span tide gates. Attached Figure Description

[0035] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific working processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0036] like Figure 1-8 As shown, the ultra-large span shore-controlled floating herringbone sluice gate of this utility model includes a pair of gate bodies 1. The head of the gate body 1 is located on the outer river side of the river channel, and the tail is connected to the balancing opening and closing device 2 set on both banks of the inner river channel. The front side of the resistance pier 21 of the balancing opening and closing device 2 is provided with a niche 3 extending towards the outer river channel. The niche 3 is adapted to the gate body 1, and the two niches 3 are parallel to each other. When navigation is required, the gate body 1 is located in the niche 3; when a storm surge occurs, the gate body 1 rotates towards the center of the river channel under the action of the balancing opening and closing device 2 until the heads meet, forming a closed state. The closing point of the two gate bodies 1 is located on the outer river side of the line connecting the ball hinges 22 of the two balancing opening and closing devices 2, which can form a stable three-hinged arch structure and play a role in blocking the tide.

[0037] Because the aforementioned tidal barrier has a large span, the gate body 1 suffers from excessive water backflow and excessive opening / closing force during operation. These problems are exacerbated when silt accumulates on the riverbed. Therefore, the gate body 1 employs a hollow metal pontoon structure with a streamlined shape that is narrow at both ends and wide in the middle. A flow passage 11 is opened in the middle of the gate body 1, and a rotating gate 12 is installed within the flow passage 11. In this embodiment, the flow passage 11 is an elongated hole along the length of the gate body 1. Multiple rotating gates 12 are arranged side-by-side within each flow passage 11, and the rotating shaft 13 of the rotating gate 12 is vertically oriented. A rotation drive mechanism connected to the rotating shaft 13 is installed on the top wall of the flow passage 11. The side-by-side arrangement of multiple rotating gates 12 improves construction convenience, while the vertical orientation of the rotating shaft 13 helps reduce water resistance during the rotation of the rotating gate 12. In practical applications, multiple flow holes 11 can be provided on the gate body 1, and a rotating gate 12 can be installed in each flow hole 11. The aforementioned rotating drive mechanism includes a telescopic cylinder 14 installed on the top wall of the flow hole 11. The telescopic cylinder 14 is located on one side of the rotating shaft 13, and the two are not coaxial. A connecting rod 15 is fixedly installed on the rotating shaft 13, and the end of the connecting rod 15 is hinged to the piston rod of the telescopic cylinder 14. When the telescopic cylinder 14 is activated, it can push the rotating gate 12 to rotate. The rotating gate 12 has a closed state that closes the flow hole 2 and an open state that allows water to flow through. When the gate body 1 is opened and closed, the rotating gate 12 is in the open state, reducing the water resistance of the gate body 1 and preventing adverse phenomena such as vertical tilting and lateral tilting of the gate body 1 during the opening and closing process. When the gate body 1 is in the closed state, the rotating gate 12 is also in the closed state, preventing water from flowing through. The aforementioned "gate within a gate" design can solve the problems of excessive water backlog and excessive opening and closing force during the opening and closing of the floating V-shaped gate, ensuring the vertical stability of the gate body 1 and contributing to the overall safety of the tide barrier gate.

[0038] Furthermore, the gate body 1 and the gate bottom plate are spaced apart, and inflatable water-stop bags 4 and telescopic support rods 5 are installed at the bottom of the gate body 1. Multiple water-stop bags 4 are spaced apart along the width direction of the streamlined gate body 1, each extending along the length direction of the gate body 1 and conforming to its outline. The support rods 5 are positioned between adjacent water-stop bags 4. When the gate body 1 is opened and closed, there is no medium inside the water-stop bags 4, and the support rods 5 are in a contracted state, creating a smooth flow channel at the bottom of the gate body 1. This solves problems such as water backlog and gate jamming due to siltation during the opening and closing of the floating miter gate. When the gate body 1 is completely closed, air is inflated into the water-stop bags 4 to seal the bottom flow channel and prevent overflow. Simultaneously, the support rods 5 extend and support the gate bottom plate, thus supporting the gate body 1.

[0039] Furthermore, anti-collision buffer layers are provided on both the water-facing and back-facing surfaces of the gate body 1.

[0040] To ensure accurate closure of the floating V-shaped gates, a positioning guide mechanism 6 is installed at the junction of the two gate bodies 1. This positioning guide mechanism 6 includes a V-shaped guide groove 61 on the top of one gate body 1 and a roller 62 on the top of the other gate body 1. The V-shaped guide groove 61 is horizontally positioned with its opening facing the other gate body 1, and the roller 62 is correspondingly fitted to the V-shaped guide groove 61. When the floating V-shaped gates are about to close, one gate body 1, under the action of the roller 62, performs a small-amplitude decelerating pendulum motion along the V-shaped guide groove 61 and quickly locks at the corner of the V-shaped groove 61, thereby ensuring accurate closure of both gates.

[0041] The aforementioned balancing opening and closing device includes a balancing opening and closing plate 23, which is mounted on the concrete structure's load-bearing pier 21 via a ball joint 22. The front end of the balancing opening and closing plate 23 is connected to the gate body 1, and the rear end is an arc-shaped structure adapted to the C-shaped groove 24 on the load-bearing pier 21. A gear and rack transmission mechanism is provided between the C-shaped groove 24 and the balancing opening and closing plate 23. Specifically, the ball joint 22 mainly consists of a mushroom-shaped shaft head, a ball bearing, and a bearing housing, etc., and can withstand the vertical load of the gate body 1 and the horizontal load during the opening and closing process. It also serves as the rotation center of the balancing opening and closing plate 23 and the gate body 1, ensuring that the gate body 1 can rotate flexibly. The aforementioned C-shaped groove 24 is used to guide the movement of the balance opening and closing plate 23; the gear and rack transmission mechanism is used to drive the balance opening and closing plate 23 to rotate, which includes an internal gear ring 25 with a concave tooth surface installed on the C-shaped groove 24, and a motor-driven drum gear 26 is installed on the top of the balance opening and closing plate 23. The drum gear 26 adopts a follower arrangement to ensure that the gear is always effectively meshed with the rack, providing opening and closing power for the floating V-shaped gate and maintaining the attitude of the floating V-shaped gate during opening, closing and moisture blocking processes. Furthermore, a slider 27 is installed on the top of the balance opening and closing device 23 and an elastic support wheel 28 is installed on the bottom. The slider 27 and the elastic support wheel 28 are both set in the C-shaped groove 24 and are respectively connected to the top and bottom surfaces of the C-shaped groove 24.

[0042] Furthermore, the gate body 1 is fixed below the balancing opening and closing plate 23. Supports 7 are installed on the gate pivot column and the oblique joint column at the tail of the gate body 1, and pillow pads corresponding to the positions of the support 7 are provided on the side wall of the resisting pier 21. The aforementioned support 7 and pillow pads adopt a continuous support-pillow pad structure. When the two gate bodies 1 are in the closed state, the overlapping support pillow pads act as the hinge point components of the floating miter gate three-hinged arch structure, transferring the water pressure (horizontal load) acting on the gate body 1 to the resisting pier 21.

[0043] This utility model features stable structure, flexible opening and closing, safe operation, and convenient maintenance. At the same time, it does not affect navigation or the hydrology and river morphology of the original river channel during the structural design, manufacturing, transportation, installation, and maintenance processes, thus minimizing the impact on the original river channel.

[0044] It should be noted that in the description of this utility model, terms such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", and "outer" indicating orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
