[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] This utility model provides a fluid energy dissipation and conveying structure for the mud silo inlet pipeline of a trailing suction hopper dredger, including two feed pipes 1, two arc-shaped pipes 3, two arc-shaped pipes 3, a tee pipe 4, several support components, and four discharge mechanisms. Each discharge mechanism includes a connecting pipe 5, a circular pipe 6, two sealing blocks 7, and several energy dissipation components. Each energy dissipation component includes a blocking plate 8 and four connecting rods 9. Each support component includes a fixing ring 10, a support rod 11, and a fixing plate 12. The aforementioned solution solves the problem of the large impact force of mud on the silo body when transporting mud in existing mud silo inlet pipelines.

[0020] In this specific embodiment, the four discharge mechanisms are respectively arranged in the middle and end sections of the corresponding feed pipes 1. One end of the connecting pipe 5 is fixedly connected to the feed pipe 1, and the other end of the connecting pipe 5 is fixedly connected to the feed pipe 1 and located below the feed pipe 1. The surface of the connecting pipe 5 is provided with a plurality of openings 2. A plurality of energy dissipation components are respectively arranged on the outside of the connecting pipe 5. One end of the four connecting rods 9 is fixedly connected to the circular tube 6, and the other end of the four connecting rods 9 is fixedly connected to the blocking plate 8. The baffle plate 8 is disposed on one side of the opening 2. The end face of the baffle plate 8 is arc-shaped. The fixing component includes a fixing pipe. When conveying soil, the soil is conveyed through the two feed pipes 1 to reduce pressure. The sludge enters the interior of the circular pipe 6 through the connecting pipe 5 and moves to both sides of the circular pipe 6. The circular pipe 6 is opened through the opening 2. The baffle plate 8 blocks one side of the opening 2. When the soil is sprayed out, it passes through the baffle plate 8 and moves outward along the baffle plate 8, reducing the impact on the silo.

[0021] Two of the sealing blocks 7 are fixedly connected to the corresponding circular tubes 6 and are respectively set at both ends of the corresponding circular tubes 6. The end of the sealing block 7 near the opening 2 is arc-shaped. The sealing block 7 blocks both ends of the circular tubes 6. When the soil moves to the end of the circular tube 6, the sealing block 7 blocks the soil, and the soil leaves from the opening 2 along the sealing block 7.

[0022] Secondly, one end of each of the two arc-shaped pipes 3 is fixedly connected to the feed pipe 1, and the other end of each of the two arc-shaped pipes 3 is fixedly connected to the corresponding connecting pipe 5, and is respectively set at the end of the corresponding feed pipe 1. The setting of the arc-shaped pipes 3 facilitates the transition of soil from the feed pipe 1 to the connecting pipe 5, and prevents the soil from causing too much impact on the transport pipe.

[0023] Secondly, the three-way pipe 4 is fixedly connected to the corresponding feed pipe 1 and is located at one end of the two feed pipes 1. One end of the three-way pipe 4 is connected to the pipe for transporting soil. Through the three-way pipe 4, the soil is transported through the two feed pipes 1 respectively, which reduces the impact force of the soil.

[0024] In addition, several of the aforementioned support components are evenly arranged above the two feed pipes 1. Each support component includes a fixing ring 10, a support rod 11, and a fixing plate 12. The fixing ring 10 covers the surface of the feed pipe 1. One end of the support rod 11 is fixedly connected to the fixing ring 10, and the other end of the support rod 11 is fixedly connected to the fixing plate 12. The fixing ring 10 fixes the surface of the feed pipe 1, fixes the fixing plate 12 to the hopper body, and fixes the transport pipe to the upper interior of the hopper body.

[0025] When using this utility model, the soil is transported through the two feed pipes 1 to reduce pressure. The sludge enters the interior of the circular pipe 6 through the connecting pipe 5 and moves to both sides of the circular pipe 6. The circular pipe 6 is opened through the opening 2, and the baffle plate 8 blocks one side of the opening 2. When the soil is sprayed out, it passes through the baffle plate 8 and moves outward along the baffle plate 8, reducing the impact on the silo. The arc-shaped pipe 3 facilitates the transition of soil from the feed pipe 1 to the connecting pipe 5, preventing the soil from causing too much impact on the transport pipe.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
