Description

Technical Field

[0001] This utility model relates to an adjustable energy dissipation box. Background Technology

[0002] The energy dissipation box is installed inside the mud tank of the trailing suction hopper dredger. Its inlet end is connected to the hull's mud discharge pipe system. It is mainly used to reduce the flow rate of the discharged mud, reduce the impact on the mud tank, thereby reducing overflow losses and improving loading efficiency.

[0003] Currently used energy dissipation boxes are mostly direct discharge types, relying primarily on piping systems and outlet grilles for energy dissipation. However, traditional energy dissipation boxes generally suffer from uneven velocity distribution at each outlet: higher velocities near the inlet and lower velocities further away, which negatively impacts loading efficiency. Furthermore, in actual operation, trailing suction hopper dredgers experience significant variations in slurry velocity and flow rate due to changing working conditions, making it difficult for traditional energy dissipation box structures to adapt to these dynamic changes.

[0004] Therefore, an adjustable energy dissipation box is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the existing defects and provide an adjustable energy dissipation box that balances the flow velocity distribution of multiple outlets inside the box, thereby optimizing the overall working effect of the energy dissipation box.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable energy dissipation box, comprising a three-way pipe, two energy dissipation pipes and multiple sets of cover plate assemblies; the upper end of the three-way pipe is connected to the ship's piping system, and the lower ends are respectively connected to one of the energy dissipation pipes, with multiple rectangular outlets evenly spaced on the side wall of each energy dissipation pipe, and a set of cover plate assemblies is provided at each rectangular outlet; The rectangular discharge outlet achieves balanced sludge discharge by adjusting the covering angle of the cover plate assembly.

[0007] Preferably, the cover plate assembly includes a cylinder bracket, a cylinder, and a cover plate; the cylinder bracket is welded to the side wall of the energy dissipation pipe, the upper end of the cylinder bracket is hinged to the fixed end of the cylinder via a first pin, the output end of the cylinder is hinged to the back of the cover plate via a second pin, and one end of the cover plate is hinged to the side wall of the rectangular outlet.

[0008] Preferably, each of the rectangular outlets has a grid attached to its inner wall.

[0009] Preferably, the three-way pipe is internally connected to a triangular guide plate.

[0010] Preferably, the system further includes a PLC controller, a stroke sensor, and a pressure sensor. The stroke sensor and the pressure sensor are disposed inside the cylinder and are communicatively connected to the PLC controller. The PLC (Programmable Logic Controller) controller is communicatively connected to the cylinder.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This adjustable energy dissipation box, compared with existing energy dissipation boxes, effectively balances the flow velocity distribution of multiple outlets within the box by adding an adjustable cover plate at the outlet, thereby optimizing the overall working effect of the energy dissipation box. This structure can better adapt to complex and changing construction conditions, further improving production efficiency.

[0012] By installing covers at the outlets of the energy dissipation box and using hydraulic cylinders to adjust their angle, combined with real-time flow velocity data monitored by sensors, the cover state can be automatically adjusted according to different operating conditions, dynamically balancing the flow velocity at each outlet. This improvement significantly enhances the adaptability of the energy dissipation box to various complex operating conditions, not only helping to increase loading speed but also effectively reducing overflow losses.

[0015] 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.

[0016] Please see Figure 1-3An adjustable energy dissipation box includes a three-way pipe 1, two energy dissipation pipes 2, and multiple sets of cover plate assemblies; the upper end of the three-way pipe 1 is connected to the hull piping system, and the lower ends are respectively connected to an energy dissipation pipe 2. Multiple rectangular discharge ports are opened at equal intervals on the side wall of each energy dissipation pipe 2, and a set of cover plate assemblies is set at each rectangular discharge port; wherein, by adjusting the covering angle of the cover plate assemblies, the balanced discharge of mud from the rectangular discharge ports is achieved.

[0017] Specifically, the cover plate assembly includes a cylinder bracket 4, a cylinder 5, and a cover plate 6. The cylinder bracket 4 is welded to the side wall of the energy dissipation pipe 2. The upper end of the cylinder bracket 4 is hinged to the fixed end of the cylinder 5 via a first pin. The output end of the cylinder 5 is hinged to the back of the cover plate 6 via a second pin. One end of the cover plate 6 is hinged to the side wall of the rectangular outlet. Each rectangular outlet has a grille 3 connected to its inner wall.

[0018] Specifically, the inside of the three-way pipe 1 is connected to a triangular guide plate 7.

[0019] Specifically, it also includes a PLC controller, a stroke sensor, and a pressure sensor. The stroke sensor and pressure sensor are installed inside the hydraulic cylinder 5 and are connected to the PLC controller. The PLC controller is also connected to the hydraulic cylinder 5.

[0020] Specifically, the upper end of the tee pipe 1 is connected to the ship's piping system by bolts, and the two sides of the tee pipe 1 are connected to the energy dissipation pipe 2 by bolts. The end of the energy dissipation pipe 2 is closed, and there are multiple rectangular outlets extending from both sides of the energy dissipation pipe 2. The grid 3 is welded into the rectangular outlets of the energy dissipation pipe 2. The cylinder bracket 4 is welded to the upper part of the energy dissipation pipe 2. The cylinder 5 is hinged to the cylinder bracket 4 by a pin. The lower end of the cylinder 5 is hinged to the cover plate 6 by a pin. The cover plate 6 is hinged to the energy dissipation pipe 2 by a pin.

[0021] During operation, the slurry enters from above the three-way pipe 1. Inside the three-way pipe 1, triangular guide plates evenly distribute the slurry into the energy dissipation pipes 2 on both sides. The slurry then exits from the outlets on both sides of the energy dissipation pipes 2 into the slurry chamber. The slurry discharge impacts the cover plate 6, causing pressure changes in the hydraulic cylinder 5. The hydraulic cylinder 5 is equipped with a stroke sensor and a pressure sensor. The control system calculates the current opening angle of the cover plate 6 by reading the stroke sensor values ​​within the cylinder 5. Then, based on the cover plate 6 angle, the outlet size of the energy dissipation pipe 2, and the pressure sensor values ​​within the cylinder 5, it calculates the flow velocity at the current outlet. By comparing the flow velocity data from multiple outlets laterally, if an imbalance in the flow velocity at the outlet of the energy dissipation pipe 2 is detected, the angle of the cover plate 6 can be adjusted by controlling the hydraulic cylinder 5 to increase or decrease the resistance at the current outlet, thereby achieving a balanced flow velocity at each outlet.

[0022] This adjustable energy dissipation box, compared to existing ones, effectively balances the flow velocity distribution across multiple outlets within the box by adding an adjustable cover at the outlet, thereby optimizing the overall working effect of the energy dissipation box. This structure can better adapt to complex and changing construction conditions, further improving production efficiency.

[0023] By installing covers at the outlets of the energy dissipation box and using hydraulic cylinders to adjust their angle, combined with real-time flow velocity data monitored by sensors, the cover state can be automatically adjusted according to different operating conditions, dynamically balancing the flow velocity at each outlet. This improvement significantly enhances the adaptability of the energy dissipation box to various complex operating conditions, not only helping to increase loading speed but also effectively reducing overflow losses.

[0024] Trailing suction hopper dredgers are one of the most important pieces of equipment for waterway dredging. To ensure dredging efficiency, minimize overflow losses, and improve loading efficiency, advanced energy dissipation boxes can significantly improve the efficiency of dredging operations. The inventors have conducted in-depth research on energy dissipation box solutions that have emerged in recent years and designed an adjustable energy dissipation box, which will greatly improve the speed and efficiency of loading operations for trailing suction hopper dredgers.
