Description

Technical Field

[0001] This invention relates to the field of deep-sea equipment technology, and in particular to a split-type rudder and a deep-sea submersible. Background Technology

[0002] Deep-sea submersibles face risks and challenges when operating in complex seabed environments. First, especially in narrow trenches, steep cliffs, or areas full of obstacles, the complex and unpredictable terrain makes them highly susceptible to collisions due to loss of attitude control or insufficient maneuverability. Such collisions can damage equipment and jeopardize mission safety. Second, the unique environment of the deep sea, including ocean currents and underwater swells, significantly increases the difficulty of attitude control. If the submersible's control system is not precise enough or its response speed is insufficient, it will struggle to maintain stability and accuracy in complex environments. This can lead to deviations from the planned route, missed targets, or even collisions. Furthermore, existing fixed rudder designs cannot flexibly and precisely adjust control surfaces, making it difficult to respond quickly and effectively to sudden obstacles and changes in terrain. This limits the submersible's maneuverability and safety in complex environments. Summary of the Invention

[0009] Optionally, the first drive assembly and the second drive assembly have the same structure. The first drive assembly includes a guide rail and a transmission rod that is slidably sleeved on the guide rail. The transmission rod is at a preset angle to the guide rail. The end of the transmission rod away from the guide rail is rotatably connected to an actuating block that dynamically abuts against the left rudder blade.

[0010] Optionally, the first drive assembly further includes a first end, a driver bushing composite, and a second end sequentially disposed on the guide rail; the driver bushing composite is slidably sleeved with the guide rail, and the end of the transmission rod near the guide rail is fixedly connected to the driver bushing composite.

[0011] Optionally, the actuating block is a semi-cylindrical block, and a guide arc surface is provided at the end of the actuating block near the left rudder blade.

[0012] Optionally, the split rudder further includes fixed bushings symmetrically arranged on the elbow plate, with both the first end and the second end connected to the fixed bushings.

[0014] Optionally, a pressure-resistant covering layer is provided on the outer surface of the first rudder and the second rudder.

[0015] The present invention also provides a deep-sea submersible, including the aforementioned split-type rudder.

[0016] In this invention, the split rudder includes an elbow plate, a first rudder rib connecting section, and a second rudder rib connecting section, the first and second rudder rib connecting sections being disposed at opposite ends of the elbow plate; the first rudder rib connecting section includes a plurality of first rudder wings arranged sequentially along the axial direction of the elbow plate; the second rudder rib connecting section includes a plurality of second rudder wings arranged sequentially along the axial direction of the elbow plate; each first rudder wing includes a left rudder blade and a first drive assembly connected to the inner cavity of the elbow plate; each second rudder wing includes a right rudder blade and a second drive assembly connected to the inner cavity of the elbow plate; the direction of the split rudder is adjusted by driving the left rudder blade to open or close via the first drive assembly and by driving the right rudder blade to open or close via the second drive assembly.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] like Figures 1 to 5As shown, an embodiment of the present invention provides a split rudder, including an elbow plate 10, a first rudder rib connecting section 20, and a second rudder rib connecting section 30. The first rudder rib connecting section 20 and the second rudder rib connecting section 30 are disposed at opposite ends of the elbow plate 10. The first rudder rib connecting section 20 includes a plurality of first rudder wings 21 arranged sequentially along the axial direction of the elbow plate 10. The second rudder rib connecting section 30 includes a plurality of second rudder wings 31 arranged sequentially along the axial direction of the elbow plate 10. Each first rudder wing 21 includes a left rudder blade 210 and a first drive assembly 40 connected to the inner cavity of the elbow plate 10. Each second rudder wing 31 includes a right rudder blade 310 and a second drive assembly 50 connected to the inner cavity of the elbow plate 10. The direction of the split rudder is adjusted by driving the left rudder blade 210 to open or close through the first drive assembly 40 and driving the right rudder blade 310 to open or close through the second drive assembly 50. The split-type rudder is composed of a first rudder rib connecting section 20 and a second rudder rib connecting section 30 arranged symmetrically. The first rudder rib connecting section 20 and the second rudder rib connecting section 30 have the same structure, and their first rudder wing 21 and second rudder wing 31 also have the same structure and number, but are arranged in a one-to-one correspondence in position and are symmetrically arranged about the elbow plate 10 axis. Each left rudder blade 210 corresponds to a first drive assembly 40, and each left rudder blade 210 can be opened or closed under the drive of the first drive assembly 40; each right rudder blade 310 corresponds to a second drive assembly 50, and each right rudder blade 310 can be opened or closed under the drive of the second drive assembly 50; thus, the position and attitude of each left rudder blade 210 and each right rudder blade 310 can be controlled independently.

[0031] In this invention, the first rudder 21 and the second rudder 31 of the split rudder, which are arranged symmetrically, are independently controlled by the first drive assembly 40 and the second drive assembly 50, respectively. This allows the number and angle of the opening or closing of the left rudder blade 210 and the right rudder blade 310 to be adjusted in real time and precisely according to requirements, significantly improving the attitude adjustment capability of the submersible in complex deep-sea environments. The left rudder blade 210 and the right rudder blade 310 can be actively deployed in a controllable manner. When encountering obstacles or emergencies, they can quickly increase the effective control area of ​​the rudder, thereby generating a sufficiently large steering torque in a very short time, realizing rapid attitude adjustment of the submersible, significantly improving the accuracy and response speed of attitude adjustment, effectively avoiding obstacles, and stabilizing the direction of navigation.

[0032] In one embodiment, such as Figure 2 and Figure 4As shown, the left rudder blade 210 and the right rudder blade 310 have the same structure. The left rudder blade 210 includes a rotating shaft 2111 mounted on the elbow plate 10 and a rudder blade body 2112 rotatably connected to the rotating shaft 2111. Understandably, the left rudder blade 210 consists of the rotating shaft 2111 and the rudder blade body 2112. The rudder blade body 2112 has a through hole through which the rotating shaft 2111 passes, thus connecting the rudder blade body 2112 to the elbow plate 10 and allowing it to rotate around the rotating shaft 2111. This rotatable connection provides great flexibility for the use of the left rudder blade 210. Simultaneously, when subjected to external forces, the left rudder blade 210 can disperse stress through rotation, avoiding stress concentration that could damage the rudder blade body 2112. The left rudder blade 210 can be extended or closed around the elbow plate 10, meaning that under different operating conditions, the left rudder blade 210 can adjust its extension angle as needed.

[0033] In one embodiment, such as Figure 2 As shown, the end face of the rudder blade body 2112 facing the elbow plate 10 is provided with an arc-shaped surface 2113, and the cross-sectional area of ​​the arc-shaped surface 2113 gradually increases in the direction towards the rotating shaft 2111; the rudder blade body 2112 is provided with a hollow cavity, and multiple spaced ribs 2114 are provided in the hollow cavity. Understandably, both ends of the elbow plate 10 are provided with curved surfaces that fit with the arc-shaped surface 2113. The arc-shaped surface 2113 increases the contact area between the two, making the fit between the rudder blade body 2112 and the elbow plate 10 tighter, reducing the eddies and resistance generated by the fluid in the gap between the two, and enhancing the stability of the rudder blade body 2112 under stress. During active deployment, the rudder blade 210 / right rudder blade 310 rapidly and actively deploys its body 2112, instantly increasing the effective control area of ​​the rudder. At this time, the rudder blade body 2112 needs to withstand significant water flow impact and turning torque. The arc-shaped surface 2113 effectively disperses stress, ensuring the rudder blade body 2112 generates a rapid response capability, allowing the submersible to generate a sufficiently large turning torque in a very short time, thus achieving rapid attitude adjustment. Understandably, the hollow cavity inside the rudder blade body 2112 significantly reduces the weight of the left rudder blade 210 / right rudder blade 310, lowers the submersible's energy consumption, and simultaneously improves the response speed and flexibility of the left rudder blade 210 / right rudder blade 310. The rib plate 2114 acts as a reinforcing rib within the hollow cavity, enhancing the structural strength and rigidity of the left rudder blade 210 / right rudder blade 310 and preventing deformation or damage during active deployment and under stress.

[0034] In one embodiment, such as Figure 1 and Figure 3As shown, the first drive assembly 40 and the second drive assembly 50 have the same structure. The first drive assembly 40 includes a guide rail 410 and a transmission rod 411 slidably sleeved on the guide rail 410. The transmission rod 411 and the guide rail 410 form a preset angle. The end of the transmission rod 411 away from the guide rail 410 is rotatably connected to an actuating block 412 that dynamically abuts against the left rudder blade 210. Understandably, the first drive assembly 40 and the second drive assembly 50 have the same structure. This symmetrical design ensures that the rudder blade bodies 2112 of the first rudder 21 and the second rudder 31 on the left and right sides of the elbow plate 10 can operate in the same way and with the same torque, thereby achieving balanced and coordinated attitude adjustment. Through the guide rail 410 and the transmission rod 411 slidably sleeved on the guide rail 410, the drive assembly can convert power into precise mechanical motion. The design of the transmission rod 411 and the guide rail 410 at a preset angle allows the transmission rod 411 to generate a thrust in a specific direction during sliding, which is then transmitted to the left rudder blade 210 / right rudder blade 310 through the trigger block 412, causing them to rotate at a certain angle. Since the left and right rudder blades 310 rotate at the same angle, this symmetrical motion can generate a stable rotational torque, thereby enabling the submersible to quickly turn and adjust its attitude.

[0035] Understandably, in emergency situations, the rudder can be rapidly adjusted by simultaneously deploying multiple left rudder blades 210 and right rudder blades 310. This multi-blade cooperative working mode allows the rudder to generate sufficient steering torque in a very short time to cope with sudden obstacles or dangerous situations. As for the preset angle setting, it can be adjusted according to the specific needs of the submersible: First, the size of the preset angle directly affects the direction and magnitude of the thrust generated by the transmission rod 411. During the design phase, the optimal angle can be determined based on factors such as the submersible's size, shape, speed, and underwater environment. For example, a larger preset angle allows the transmission rod 411 to generate greater lateral thrust, thus achieving a larger steering angle over a shorter distance, suitable for scenarios requiring rapid turning; while a smaller preset angle allows the thrust to be distributed more evenly on the rudder blade body 2112, suitable for situations requiring precise attitude adjustments. Furthermore, the preset angle setting also needs to consider the submersible's hydrodynamic characteristics. Different submersibles experience different water resistance and pressure distributions during underwater navigation. By adjusting the preset angle, the force distribution on the rudder blade body 2112 can be optimized, ensuring efficient maneuverability at different speeds and depths. Meanwhile, the preset angle can also be adjusted according to the mission requirements of the submersible. For example, when performing high-precision positioning tasks, the preset angle can be set to a smaller value to achieve more precise fine-tuning; while during rapid obstacle avoidance or emergency turns, the preset angle can be increased to obtain greater steering torque.

[0036] In one embodiment, such as Figure 1 and Figure 3 As shown, the first drive assembly 40 further includes a first end 413, a drive bushing composite 414, and a second end 415 sequentially disposed on the guide rail 410; the drive bushing composite 414 is slidably sleeved with the guide rail 410, and the end of the transmission rod 411 near the guide rail 410 is fixedly connected to the drive bushing composite 414. Understandably, the slidable sleeve design of the drive bushing composite 414 and the guide rail 410 provides precise guidance and stable support for the movement of the transmission rod 411. This structure ensures that the transmission rod 411 remains on a predetermined track during sliding, allowing the transmission rod 411 to perform flexible telescopic movement on the guide rail 410, thereby dynamically changing the rotation angle of the rudder body 2112 according to the submarine's navigation state and attitude adjustment requirements. The first end 413 and the second end 415 can serve as fixing points for the guide rail 410, ensuring stable installation of the guide rail 410 and preventing displacement or vibration during movement. At the same time, these two ends can also serve as a limit to prevent the driver bushing composite 414 from exceeding the predetermined range during sliding.

[0037] In one embodiment, such as Figure 3 As shown, the actuating block 412 is a semi-cylindrical block, and a guide arc surface 4121 is provided at the end of the actuating block 412 near the left rudder blade 210. Understandably, the cylindrical actuating block 412 makes more uniform contact with the left rudder blade 210, effectively transferring thrust to the rudder blade body 2112 while reducing stress concentration; the semi-cylindrical shape also adapts to the rotational motion of the rudder blade, avoiding unnecessary friction or jamming during contact, thereby improving the system's reliability and response speed. More importantly, the guide arc surface 4121 provided at the end of the actuating block 412 near the left rudder blade 210 further optimizes the contact and motion relationship between the actuating block 412 and the rudder blade. The guide arc surface 4121 can guide and buffer when the actuating block 412 pushes the rudder blade to rotate. When the transmission rod 411 pushes the actuating block 412 to contact the rudder blade body 2112, the guide arc surface 4121 can make the contact process smoother and reduce the impact force, thereby protecting the rudder blade and the actuating block 412 from damage. At the same time, the guide arc surface 4121 can also ensure that the actuating block 412 always maintains the correct direction and angle when pushing the rudder blade body 2112, further improving the accuracy and stability of the rotation of the left rudder blade 210 / right rudder blade 310.

[0038] In one embodiment, such as Figure 1 and Figure 3As shown, the split-type rudder also includes fixed bushings symmetrically arranged on the elbow plate 10, with the first end 413 and the second end 415 both connected to the fixed bushings. Understandably, the fixed bushings provide a reliable connection point for the first end 413 and the second end 415, allowing the guide rail 410 to be securely mounted on the elbow plate 10, ensuring that the transmission rod 411 remains on the correct track during sliding, and preventing mechanical failures caused by loosening or displacement of the guide rail 410.

[0039] In one embodiment, such as Figure 1 , Figure 4 and Figure 5 As shown, the number of the first rudder 21 and the second rudder 31 is set to 3-5, and the first rudder 21 and the second rudder 31 are symmetrically arranged about the central axis of the elbow plate 10. Understandably, the number of the first rudder 21 and the second rudder 31 can be set according to requirements. The adjustability of the number of rudders allows the submersible to select the most suitable configuration based on its size, speed, mission type, and expected operating environment. This multi-rudder design (each rudder corresponds to a rudder blade body 2112) enables the submersible to achieve more precise direction adjustment and attitude control during navigation through the coordinated action of multiple rudder blade bodies 2112. Compared to a single rudder or a smaller number of rudders, multiple rudders can generate a more complex and refined torque distribution, thereby achieving rapid and stable turning under different speed, depth, and current conditions.

[0040] In one embodiment, such as Figure 1 As shown, a pressure-resistant covering layer is provided on the outer surface of the first rudder 21 and the second rudder 31. Understandably, the pressure-resistant covering layer can be a structural skin. The left rudder blade 210 / right rudder blade 310 has a high degree of integration with the geometric features of the structural skin. The smooth shape design can significantly reduce the resistance and eddies generated by water flow on the surface of the rudder blade body 2112, thereby reducing the energy consumption of the submersible during navigation and improving its navigation efficiency, enabling the rudder blade to withstand higher water pressure.

[0041] In one embodiment, such as Figure 4 and Figure 5 As shown, when the number of first rudder 21 and second rudder 31 is set to 5, all the first rudder 21 and second rudder 31 will close without adjusting the attitude of the deep-sea submersible itself, so as to ensure that the hull of the deep-sea submersible is smooth and that it can navigate with minimal water resistance.

[0042] When it is necessary to adjust the roll angle of the deep-sea submersible, or when the submersible's roll angle needs to be adjusted to a horizontal state due to seabed turbulence, the drive shaft sleeve composite 414 moves along the guide rail 410 in a suitable direction and generates thrust through the transmission rod 411. This causes the left rudder blade 210 of one of the first rudder wings 21 to rotate by a certain angle, and simultaneously causes the right rudder blade 310 of one of the second rudder wings 31 to rotate by the same angle. The left and right rudder blades 210 and 310 are selected in appropriate positions according to actual needs. When rotating by the same angle, a rotational torque is generated. In case of emergency, multiple rudder wings can be deployed simultaneously to adjust the attitude.

[0043] When the deep-sea submersible needs to turn, all the left rudder blades 210 and all the right rudder blades 310 are opened, but the left and right rotation angles are different. The pressure difference torque formed by the incoming flow is used to correct its own direction of travel.

[0044] When the submersible needs to reduce speed urgently, all left rudder blades 210 and all right rudder blades 310 are opened to their maximum angle to reduce the submersible's speed to the maximum extent by increasing the contact area with the incoming flow.

[0045] The present invention also provides a deep-sea submersible, including the aforementioned split-type rudder. In the split-type rudder of the above embodiments of the present invention, the split-type rudder includes an elbow plate 10, a first rudder bone connecting section 20, and a second rudder bone connecting section 30. The first rudder bone connecting section 20 and the second rudder bone connecting section 30 are disposed at opposite ends of the elbow plate 10. The first rudder bone connecting section 20 includes a plurality of first rudder wings 21 arranged sequentially along the axial direction of the elbow plate 10. The second rudder bone connecting section 30 includes a plurality of second rudder wings 31 arranged sequentially along the axial direction of the elbow plate 10. Each first rudder wing 21 includes a left rudder blade 210 and a first drive assembly 40 connected to the inner cavity of the elbow plate 10. Each second rudder wing 31 includes a right rudder blade 310 and a second drive assembly 50 connected to the inner cavity of the elbow plate 10. The direction of the split-type rudder is adjusted by driving the left rudder blade 210 to open or close via the first drive assembly 40 and driving the right rudder blade 310 to open or close via the second drive assembly 50.

[0046] In the deep-sea submersible of the above embodiments of the present invention, the first rudder 21 and the second rudder 31 of the split-type rudder are symmetrically arranged and their potentials are independently controlled by the first drive assembly 40 and the second drive assembly 50, respectively. This allows the number and angle of the opening or closing of the left rudder blade 210 and the right rudder blade 310 to be adjusted in real time and precisely according to the needs. This significantly improves the attitude adjustment capability of the submersible in complex deep-sea environments. The left rudder blade 210 and the right rudder blade 310 can be actively deployed in a controllable manner. When encountering obstacles or emergencies, they can quickly increase the effective control area of ​​the rudder, thereby generating a sufficiently large steering torque in a very short time, realizing rapid attitude adjustment of the submersible, significantly improving the accuracy and response speed of attitude adjustment, effectively avoiding obstacles, and stabilizing the direction of navigation.
