Description

Technical Field

[0001] This utility model relates to the field of ship lift inlet technology, and in particular to an island-type box-shaped inlet structure with front and side views. Background Technology

[0002] In existing ship lift renovation projects, preserving the original ship lift structure and utilizing the original ship lift channel minimizes the economic, safety, and environmental impacts of demolition and reconstruction. Furthermore, the inlet flow conditions are crucial for the safety of vessels navigating within the waterway. Therefore, the rational spatial arrangement and type selection of the inlet are important aspects of the ship lift's economic, safe, and hydraulic design. For large ship lifts with high flow rates and velocities, the inlet is a critical issue in the water conveyance system design, attracting widespread attention from designers. Traditional inlet structures are prone to generating vortices, which can cause air intake or the ingestion of floating debris, leading to siltation and the introduction of bedload silt into the ship lift's water conveyance system. Therefore, a box-type inlet structure with both island-style forward and lateral inlets is required. Utility Model Content

[0003] The purpose of this utility model is to provide an island-type box-shaped water inlet structure with front and side views, which solves the technical problem that existing water inlet structures are prone to generating vortices, causing air intake or the intake of floating objects, resulting in siltation and the entry of bedload silt into the water conveyance system of the ship lift.

[0004] Based on the principles of the ship lift inlet layout, the inlet arrangement is optimized. Combined with the specific conditions of the project, the new inlet structure has significant competitive advantages over the traditional type in terms of reducing construction costs, ensuring ship navigation safety, preventing severe whirlpools in front of the inlet, avoiding air intake or inhalation of floating objects due to whirlpools, reducing siltation, and preventing bedload silt from entering the ship lift water supply system.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An island-type box-shaped water inlet structure with front and side orientations includes a frame body, with several side water inlets on both sides of the frame body, a front water inlet at the front end of the frame body, and a water outlet at the rear end of the frame body.

[0006] Furthermore, the frame is designed as a cuboid structure, with a hollow structure inside, and the side inlet, front inlet, and outlet are interconnected.

[0007] Furthermore, both the side inlet and the front inlet are equipped with trash racks, which are detachable.

[0008] Furthermore, a trash rack upper insertion port is provided directly above the side inlet and the front inlet. The trash rack can be inserted or removed through the trash rack upper insertion port to clean or replace the trash rack.

[0009] Furthermore, both the side inlets and the front inlets are placed underwater, with the side inlets arranged symmetrically.

[0010] Furthermore, both the side inlet and the front inlet are equipped with inlet gates, which are used to open or close the water intake.

[0011] Furthermore, both the side inlet and the front inlet are designed as trapezoidal structures, with a larger outer surface and a gradually decreasing inner surface.

[0012] Furthermore, the two side columns of both the side inlet and the front inlet are designed with arc-shaped structures to reduce water flow resistance.

[0013] Furthermore, the frame is designed as a single unit.

[0014] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects: (1) Compared with the traditional type, this utility model has obvious competitive advantages in solving the problems of reducing engineering construction costs, ensuring ship navigation safety, preventing serious vortices from occurring in front of the water inlet, avoiding the intake of air or floating objects due to vortexes, reducing siltation, and preventing bedload silt from entering the water conveyance system of the ship lift.

[0015] (2) Appropriately enlarge the inlet area, reduce the inlet flow velocity, and design the orifice to be well streamlined so that the water flow is straight and prevents water flow separation; make the flow distribution of each branch orifice and the flow velocity of the nearby waterway more uniform, and at the same time improve the efficiency of the water conveyance system; ensure that the inlet leading edge length is sufficient to ensure that the inlet has a sufficient water intake area, and place all orifices underwater with sufficient orifice submersion depth to reduce the flow velocity gradient of the inlet orifice and weaken or prevent vortices.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0019] like Figure 1-4 As shown, an island-type box-shaped water inlet structure with front and side orientations includes a frame body 3. Several side water inlets 1 are provided on both sides of the frame body 3. A front water inlet 2 is provided at the front end of the frame body 3, and a water outlet 6 is provided at the rear end of the frame body 3. The number of side water inlets 1 on each side is four, which are equally spaced and are positioned opposite each other.
