Description

Technical Field

[0001] This utility model relates to a flow guiding structure, and more particularly to a flow guiding structure and a submersible. Background Technology

[0002] Submersibles play a vital role in many fields, including ocean exploration, underwater operations, and military applications. With the continuous development of related technologies, the performance requirements for submersibles are becoming increasingly stringent, with underwater speed and energy efficiency becoming key indicators for evaluating their performance.

[0003] When traditional underwater vehicles (UVs) travel in water, the impact of water flow on their propulsion systems cannot be underestimated. The propeller blades, a core component of the propulsion system, directly bear the impact of the water flow during operation. Due to the complexity and instability of water flow, the blades are often subjected to uneven impacts, which not only reduces their rotational efficiency but also leads to accelerated wear and shortens their lifespan. For example, in areas with strong currents, or when the UV needs to rapidly change course and speed, the impact of the water flow on the blades increases significantly, making it difficult for the blades to operate at their optimal design, thus severely affecting the overall speed of the UV.

[0004] Therefore, it is urgent to develop a flow-guiding structure that can effectively avoid and reduce the impact of water flow on the propeller blades, improve the propeller blade rotation efficiency, and increase the speed of the submersible. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a flow guide structure and a submersible that can effectively avoid and reduce the impact force of water flow on the propeller blades, improve the propeller blade rotation efficiency and the submersible's moving speed.

[0006] The technical solution of this utility model is as follows: a submersible flow guiding structure, including a first flow guiding device and a second flow guiding device. The second flow guiding device is installed inside and below the first flow guiding device. The first flow guiding device includes a conical head, a threaded connector, and a first flow divider. The top of the conical head has an inwardly stepped surface. The conical head is connected to the bottom of the motor. The threaded connector is connected to the bottom shell of the submersible through threads. The first flow divider is connected between the conical head and the threaded connector. The outer side of the first flow divider has an inwardly concave arc to form a waist-shaped structure for the flow guiding. The second flow guiding device includes an upper connecting ring, a lower connecting ring, and a second flow divider. The upper connecting ring is sleeved on the lower outer side of the conical head, and the lower connecting ring is sleeved on the inner side of the threaded connector. The outer side of the lower connecting ring is tightly attached to the inner side of the threaded connector. A second flow divider is connected between the lower connecting ring and the upper connecting ring. The lower part of the second flow divider is stuck above the threaded connector.

[0007] A submersible includes a submersible hull, a submersible bottom shell, a motor, and rotating blades. The motor is installed in the lower part of the submersible hull, the rotating blades are installed on the output shaft below the motor, a flow guide structure is installed below the motor, and the submersible bottom shell is installed below the flow guide structure.

[0008] The beneficial effects are as follows: The first diverter plate has an inward concave arc on its outer side, which makes the flow guide form a waist-shaped structure, which can drive the submersible to move. During the movement of the submersible, it can reduce the impact force of the water flow on the rotating blades, improve the rotation efficiency of the rotating blades, and thus increase the movement speed of the submersible. The second diverter plate can not only guide the flow, but also, together with the upper connecting ring, the lower connecting ring and the second diverter plate, can provide support for the conical head and its upper components, making the installation of the conical head and its upper components more stable.
