Description

Technical Field

[0001] This utility model relates to the field of marine exploration equipment technology, and in particular to a novel biomimetic whale towing hull. Background Technology

[0002] Traditional towed hulls for ocean exploration typically employ a simple cylindrical shape with a fixed tail fin at the rear. These hulls usually rely on counterweights or their own weight for submersion, resulting in a passive and rudimentary method of depth adjustment, making it difficult to achieve rapid and precise depth changes during towing. Furthermore, the fixed shape and tail fin design lead to significant hydrodynamic drag, limiting towing speed. In complex ocean currents, their attitude self-stabilization and disturbance resistance capabilities are limited, impacting the stability of the exploration platform and data quality. Additionally, their internal structure often lacks integration, making maintenance and upgrades inconvenient. Therefore, there is an urgent need for a towed hull with low drag, intelligent depth and attitude adjustment capabilities, and a compact and reliable structure. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a novel biomimetic whale-towed cabin, comprising:

[0004] The keel of the cabin serves as the main load-bearing structure for the entire cabin.

[0005] The transmitting transducer is connected to the front end of the cabin keel via a transmitting transducer mounting bracket;

[0006] The receiver transducer I and the receiver transducer II are provided. The receiver transducer I is located below the transmitter transducer, and the two receiver transducers II are symmetrically arranged on both sides of the cabin. The receiver transducer I is connected to the cabin keel through a receiver transducer fixing frame, and the receiver transducer II is directly connected to the cabin keel.

[0007] The shaped fairing has a fairing frame inside. The front end of the fairing frame is connected to the transmitter transducer mounting frame, and the rear end is connected to the cabin keel. The shaped fairing covers the outside of the fairing frame and together they form a biomimetic whale streamlined front cabin shell.

[0008] Depth-fixed wings are symmetrically arranged on both sides of the keel of the cabin and are connected to the keel of the cabin through a servo linkage mechanism;

[0009] A tail fin is located at the rear of the cabin.

[0010] The tail fairing is connected to the rear end of the hull keel and has a support frame inside. The attitude tail fin is mounted on the support frame through a linkage mechanism.

[0011] The hull skin covers the outside of the hull keel and is located at the lower end of the shaped fairing;

[0012] The electronic cabin is housed within the keel of the underwater hull. It can intelligently adapt to complex sea conditions and autonomously complete stable exploration operations at designated depths, significantly improving the automation level and mission execution efficiency of underwater unmanned exploration equipment.

[0013] In one embodiment of this utility model, the servo linkage mechanism is controlled by an electronic control terminal to drive the depth-fixing wing and attitude tail wing to rotate in order to adjust the angle.

[0014] In one embodiment of this utility model, the cabin skin is provided with water-permeable holes.

[0015] In one embodiment of this utility model, the transmitting transducer, receiving transducer I, receiving transducer II, and the electronic cabin constitute a detection signal processing unit.

[0016] In one embodiment of this utility model, the cabin keel, the transmitting transducer mounting bracket, the receiving transducer mounting bracket, the fairing frame, and the tail fairing support frame are fixed together by threaded connection.

[0017] Compared with the prior art, the above-mentioned technical solution of this utility model has the following advantages: The novel biomimetic whale towed hull of this utility model significantly reduces underwater navigation resistance through the biomimetic whale streamlined shell design; the electric control linkage mechanism independently drives the depth-fixing wing and attitude tail wing, realizing stepless and precise adjustment of diving depth and real-time stable control of the travel attitude; the whole adopts a modular assembly structure, with the hull keel as the core load-bearing frame, which has high integration, stable structure and easy maintenance, while ensuring the detection function, comprehensively improving the mobility, stability and environmental adaptability of the towed hull.

[0022] like Figure 1 and Figure 2 As shown, this embodiment provides a novel biomimetic whale-shaped towing hull. The overall design of the hull mimics the shape of a whale and is streamlined to significantly reduce fluid resistance during towing in water. Adjustable winglets enable flexible control of diving depth and attitude.

[0023] It includes: a transmitting transducer 1 at the foremost position, receiving transducers I and II following closely behind, a fairing 4 covering the front structure, depth-fixing wings 5 ​​symmetrically arranged on both sides of the midsection of the cabin, attitude tail 6 at the rear, and partially exposed cabin skin 11.

[0024] Specifically, the hull keel 7 is the main load-bearing structure of the entire towed hull, made of high-strength materials, and arranged longitudinally along the hull. All other major functional components are directly or indirectly installed, connected, or covered by the hull keel 7, forming a stable overall frame.

[0025] The transmitting transducer 1 is connected to the front end of the cabin keel 7 via a dedicated transmitting transducer mounting bracket 9. The receiving transducer I2 is located below the transmitting transducer 1, and two receiving transducers II3 are symmetrically arranged on both sides of the cabin. Specifically, the receiving transducer I2 is fixedly connected to the cabin keel 7 via a receiving transducer mounting bracket 10, while the receiving transducer II3 is directly connected to the cabin keel 7 via its mounting base. This arrangement ensures the geometric stability of the acoustic array.

[0026] To achieve a biomimetic streamlined shape, a shaped fairing 4 is provided at the front of the cabin. This fairing contains a fairing frame 8, whose front end is connected to the launch transducer mounting bracket 9, and its rear end is connected to the cabin keel 7, thus providing stable support. The shaped fairing 4 acts as a skin covering the exterior of the fairing frame 8, forming a smooth and flowing front shape.

[0027] Following the fairing 4, the main body of the hull keel 7 is covered by the hull skin 11. The hull skin 11 is also designed as a curved surface that conforms to hydrodynamics, and water-permeable holes can be opened on it as needed to further optimize the flow field and reduce drag.

[0028] The tail fairing 13 is connected to the end of the keel 7 of the cabin. It also has a supporting frame inside to accommodate and support the tail mechanism and smoothly transitions with the front shape to complete the complete whale biomimetic shape.

[0029] The fixed-depth wing 5 consists of two pieces, which are symmetrically hinged to the middle of both sides of the keel 7 of the hull via a pivot shaft and a servo linkage mechanism. The servo can drive this linkage mechanism to precisely control the angle of attack of the fixed-depth wing 5.

[0030] The attitude tail fin 6 is mounted inside the tail fairing 13 at the end of a linkage mechanism on its supporting frame. This linkage mechanism is also driven by a servo motor and can control the deflection angle of the attitude tail fin 6. The servos of both the depth stabilizer wing 5 and the attitude tail fin 6 are uniformly coordinated and controlled by the in-cabin electronic control terminal.

[0031] The electronics compartment 12, as an independent sealed unit, is directly housed and fixed within the internal cavity of the keel 7 of the hull. It integrates signal processing circuitry, a data acquisition module, a power management module, and the core components of the electronic control terminal for controlling the depth stabilizer wing 5 and the attitude tail wing 6. Transmitter 1, receiver I 2, and receiver II 3 are all connected to the electronics compartment 12 via internal cables.

[0032] In this embodiment, the novel biomimetic whale-towed hull is assembled by first installing components such as the transmitter transducer mounting bracket 9 and the receiver transducer mounting bracket 10 into designated positions on the hull keel 7. Then, transmitter transducers 1, receiver transducers I2 and II3 are installed onto their respective mounting brackets or keels. Next, the fairing frame 8 is installed, and its front and rear ends are connected to the transmitter transducer mounting bracket 9 and the hull keel 7, respectively. Afterward, the electronics bay 12, integrating electronic equipment, is installed inside the hull keel 7, and all cables are connected. Then, the depth-fixing wing 5 and its servo linkage mechanism are installed on both sides of the hull keel 7, and the attitude tail wing 6 and its linkage mechanism are installed onto the frame of the tail fairing 13. The tail fairing 13 is then connected to the rear end of the hull keel 7. Finally, the shaped fairing 4 and the hull skin 11 are sequentially assembled onto their respective frames, and all external skins are fixed using wedges, threaded fasteners, etc., forming a complete, smooth, streamlined outer shell.

[0033] In summary, during operation, the towed hull is towed forward by the ship via cables. The streamlined outer shell (shaped fairing 4, hull skin 11, and stern fairing 13) effectively disperses water flow and significantly reduces headwind resistance.

[0034] When a change in diving depth is required, the electronic control terminal issues a command to drive the servo motor of the depth-fixing wing 5, changing the synchronous angle of attack of the two depth-fixing wing 5s. The change in angle of attack immediately changes the lift generated by the water flow on the wing blades, thereby providing an additional force in the vertical direction to the hull, causing the hull to rise or submerge, achieving stepless depth adjustment.

[0035] When adjusting depth or responding to water flow disturbances, the attitude tail fin 6 deflects under the command of the electronic control terminal, generating a corrective torque to adjust and stabilize the pitch, yaw and other attitudes of the cabin in real time, preventing the cabin from becoming unstable or rolling.

[0036] Through the specific structural connections and spatial layout described above, this invention tightly integrates biomimetic shape, modular functional units, and active control mechanisms, significantly improving the fluid performance, maneuverability, and stability of the towed hull while ensuring detection capabilities. It is particularly suitable for marine exploration scenarios where the detection depth has dynamic variations.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
