Description

Technical Field

[0001] This utility model relates to the field of ship bridge technology, and in particular to a device for large ships to pass through low-headroom bridges and culverts. Background Technology

[0002] In the field of ship passage through bridges and culverts, the passage of large vessels through low-headroom bridges and culverts has always been a key concern for the industry. Most existing devices for passing through low-headroom bridges and culverts rely on adjusting the height of the buoy to ensure smooth passage. However, these devices have significant drawbacks in practical use. On the one hand, pumping water alters the buoyancy and draft of the buoy, resulting in poor stability for the vessel when passing through the bridge or culvert, greatly increasing the risk of collision. On the other hand, some devices have complex structures and cumbersome operating procedures, making it difficult to guarantee the safe and rapid passage of vessels through bridges and culverts, seriously affecting shipping efficiency and safety.

[0003] To address this, a device for large ships to pass through low-headroom bridges and culverts is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a device for large ships to pass through low-headroom bridges and culverts, aiming to solve or improve at least one of the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides a device for large ships to pass through low-headroom bridges and culverts, comprising:

[0006] A floating hull is installed below the bridge opening of a low-headroom bridge culvert; the inner wall of the floating hull is provided with a water storage layer.

[0007] A gate assembly, comprising an upstream gate and a downstream gate, wherein the upstream gate and the downstream gate are respectively installed on opposite sides of the floating body compartment, and the upstream gate is positioned closer to the upstream side;

[0008] A pumping assembly is installed on the floating body cabin, with one end of the pumping assembly connected to the water storage interlayer and the other end connected to the inner cavity of the floating body cabin.

[0009] According to the present invention, a device for large ships to pass through low-headroom bridges and culverts is provided. The pumping assembly includes a first pipe, a second pipe, and a pump. The pump is installed on the floating body cabin. The first pipe and the second pipe are respectively installed at both ends of the pump. The first pipe is fixedly connected to and communicates with the water storage interlayer. The second pipe communicates with the inner cavity of the floating body cabin.

[0010] According to the present invention, a device for large ships to pass through low-headroom bridges and culverts is provided, wherein the outer wall of the floating body cabin is equipped with a connector, and the connector is fixedly installed on the fixed column of the low-headroom bridge and culvert.

[0011] According to the present invention, a device for large ships to pass through low-headroom bridges and culverts is provided, wherein anti-collision strips are installed on the inner side wall of the floating body cabin.

[0012] According to the present invention, a device for large ships to pass through low-headroom bridges and culverts is provided, wherein water level sensors are installed on the inner wall of the water storage jacket and the inner wall of the floating body cabin.

[0013] According to the present invention, a device for large ships to pass through low-headroom bridges and culverts is provided, wherein a water valve and a flow meter are installed in the first pipeline.

[0014] The present invention discloses the following technical effects:

[0015] This utility model involves fixing a floating hull under an existing low-clearance bridge opening. The floating hull floats on the water surface and is used for the passage of large vessels. In use, the upstream and downstream gates are first opened. After the large vessel enters the floating hull, the upstream and downstream gates are closed. Then, the water in the floating hull is pumped into the water storage interlayer using a pumping unit, which lowers the water level in the floating hull, allowing the vessel to pass safely through the culvert. After the vessel passes through the bridge culvert, the water in the water storage interlayer is pumped back into the floating hull, raising the water level in the floating hull to the river level. The upstream and downstream gates are then opened to allow the large vessel to smoothly enter the river.

[0016] This invention enables large ships to pass quickly through bridges and culverts by adjusting the water level in the floating chamber using a pumping assembly. The water in the floating chamber is pumped into the water storage interlayer, so that the buoyancy of the floating chamber remains unchanged during the round-trip pumping process, and the draft of the floating chamber remains unchanged, thus enabling large ships to pass safely and smoothly through low-headroom bridges and culverts.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Reference Figures 1-2 This utility model provides a device for large ships to pass through low-headroom bridges and culverts, comprising:

[0024] The floating hull 1 is installed below the bridge opening of the low-clearance bridge culvert 7; the inner wall of the floating hull 1 is provided with a water storage layer; the depth of the floating hull 1 should be such that the boat can pass through the bridge opening and has a moderate draft when the river is at its highest water level.

[0025] The gate assembly includes an upstream gate 2 and a downstream gate 3, which are respectively installed on opposite sides of the floating body compartment 1, with the upstream gate 2 positioned closer to the upstream side.

[0026] The pumping assembly is installed on the floating body compartment 1. One end of the pumping assembly is connected to the water storage interlayer, and the other end is connected to the inner cavity of the floating body compartment 1.

[0027] With this configuration, the present invention fixes the floating hull 1 under the existing low-clearance bridge opening. The floating hull 1 floats on the water surface and is used for the passage of large ships 8. In use, the upstream gate 2 and the downstream gate 3 are opened first. After the large ship 8 enters the floating hull 1, the upstream gate 2 and the downstream gate 3 are closed. Then, the water in the floating hull 1 is pumped into the water storage interlayer using the pumping assembly, so that the water level in the floating hull 1 is lowered, allowing the ship to pass safely through the culvert. After the ship passes through the bridge culvert, the water in the water storage interlayer is pumped back into the floating hull 1 using the pumping assembly, raising the water level in the floating hull 1 to the river level. The upstream gate 2 and the downstream gate 3 are then opened to allow the large ship to smoothly enter the river.

[0028] This invention enables large vessels 8 to pass quickly through bridges and culverts by adjusting the water level in the floating chamber 1 using a pumping assembly. The water in the floating chamber 1 is pumped into the water storage interlayer, ensuring that the buoyancy of the floating chamber 1 remains constant during the pumping process. At the same time, the draft of the floating chamber 1 remains constant, allowing large vessels 8 to pass safely and smoothly through low-clearance bridges and culverts 7. The entire process utilizes the water storage interlayer to achieve water circulation rather than external discharge, maintaining a constant total buoyancy of the floating chamber 1 to ensure a stable draft, and creating a safe passage window through the water level difference. Ultimately, this ensures both the efficiency of vessel passage and the structural safety of the bridge and culvert.

[0029] The scheme is further optimized. The pumping component includes a first pipe 4, a second pipe 5, and a pump 6. The pump 6 is installed on the floating body chamber 1. The first pipe 4 and the second pipe 5 are respectively installed at both ends of the pump 6. The first pipe 4 is fixedly connected to and communicates with the water storage interlayer. The second pipe 5 communicates with the inner cavity of the floating body chamber 1.

[0030] Once the vessel enters the floating chamber 1, the pump 6 is activated, pumping water from the water storage interlayer into the inner cavity of the floating chamber 1 through the first pipe 4 (or vice versa). The second pipe 5 directly connects to the interior of the floating chamber 1, forming an efficient water circulation loop. This process maintains a constant total mass of the floating chamber through water weight transfer rather than external discharge, thus ensuring constant buoyancy and draft, and enabling dynamic adaptation of the vessel's passage height to bridge and culvert clearance restrictions.

[0031] Further optimizing the design, the outer wall of the floating hull 1 is equipped with connectors, which are fixedly installed on the fixed columns of the low-headroom bridge culvert 7 to ensure the safety of the bridge culvert. The floating hull 1 can be manufactured off-site and floated to the bridge culvert.

[0032] The connectors use prestressed bolts or welded connectors to achieve rigid connection with the fixed columns of the low-headroom bridge and culvert, forming an anti-overturning force system: the connectors directly transmit the buoyancy of the ship, the ship load and the impact force of the water flow to the bridge pier foundation, avoiding the concentration of load on the bridge structure.

[0033] Further optimization of the design involves installing anti-collision strips on the inner wall of the floating hull 1. These anti-collision strips are made of high-elasticity rubber or polyurethane and are arranged in a continuous corrugated pattern along the inner wall of the floating hull 1. When the ship collides with the bulkhead, the anti-collision strips disperse the impact force through surface protrusion deformation, thereby reducing the impact force of the collision.

[0034] To further optimize the design, water level sensors are installed on the inner walls of both the water storage jacket and the floating chamber 1 to monitor the water level.

[0035] The scheme has been further optimized. A water valve and a flow meter are installed in the first pipe 4. The water valve controls the direction of water flow and its opening and closing, and the flow meter monitors the water volume changes in real time to ensure the accuracy of water level regulation.
