Description

Technical Field

[0001] This utility model relates to the field of precision positioning technology for deep-sea small piles, and in particular to a precision positioning device for deep-sea small piles based on ultrasound. Background Technology

[0002] Deep-sea small-pile positioning devices face significant challenges in complex ocean current environments. Lateral water flow impacts can easily cause the device to drift, directly affecting the stability of ultrasonic signals and positioning accuracy. Traditional positioning devices mostly adopt static flow guiding structures or fixed-angle designs, which cannot dynamically adapt to omnidirectional water flow (such as eddies, undercurrents, and other complex flow fields). Their flow diversion efficiency is low, making it difficult to effectively weaken the impact force of the water flow, resulting in frequent tilting and displacement of the device in strong current environments.

[0003] In existing technologies, some devices attempt to adjust the guide angle through mechanical structures, but lack collaborative design, making it difficult to achieve dynamic and precise control. At the same time, most devices do not combine the guide reaction force for attitude self-calibration, requiring frequent intervention from external control systems. This not only results in delayed response but also increases energy consumption and structural complexity, making it difficult to meet the long-term stability requirements of high-precision positioning in the deep sea. Therefore, an ultrasonic-based deep-sea small pile precision positioning device is proposed to solve the above problems. Utility Model Content

[0007] A rotating arm is also provided between the rotating shaft and the rotating arm. One end of the rotating arm is slidably connected in the strip groove, and the other end is fixedly connected to a rotating column. The rotating column extends out of the pile body, and a fixing component is provided at its bottom end. A guide plate for precise pointing is fixedly connected in the middle of the rotating column.

[0019] 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.

[0020] Reference Figures 1 to 3This utility model provides an embodiment of a deep-sea small pile precision positioning device based on ultrasound, comprising a pile body 1, a motor 2 fixedly connected inside the pile body 1, a rotating arm 3 fixedly connected to the drive end of the motor 2, a rotating shaft 5 rotatably connected inside the pile body 1, a rotating frame 4 fixedly sleeved on the rotating shaft 5, a strip groove opened on the rotating frame 4, and the free end of the rotating arm 3 slidably connected in the strip groove; a rotating arm 6 is also provided between the rotating shaft 5 and the rotating arm 3, one end of the rotating arm 6 is slidably connected in the strip groove, and the other end is fixedly connected to a rotating column 7, the rotating column 7 extends out of the pile body 1, and a fixing component is provided at its bottom end; a guide plate 8 for precise pointing is fixedly connected in the middle of the rotating column 7.

[0021] The pile body 1 serves as the foundation structure of the device, providing overall support and protection for the internal components. A motor 2 is fixedly connected inside the pile body 1, which is designed as a power source. A rotating arm 3 is fixedly connected to the drive end of the motor 2, which is designed to convert the rotational motion of the power source into oscillation. A rotating frame 4 is slidably connected to the outside of the rotating arm 3, which is designed to transmit and change the direction of motion. A rotating shaft 5 is fixedly connected to one end of the rotating frame 4, which is designed to provide a fulcrum for rotation and constrain the motion trajectory of the rotating frame 4. One end of the rotating shaft 5 is rotatably connected to the inside of the pile body 1.

[0022] The rotating arm 6 amplifies and transmits the motion of the rotating frame 4. The external rotation of the rotating arm 6 is connected to the internal structure of the pile body 1. One end of the rotating arm 6 is fixedly connected to the rotating column 7. The rotating column 7 is designed as a linkage and fixing component to achieve coordinated action. The external rotation of the rotating column 7 is fixedly connected to the guide plate 8. The guide plate 8 is designed as an anchoring device to resist the force of water flow and waves. The function of the guide plate 8 is to facilitate guidance in the seabed current. The guide plate 8 is triangular in shape and painted with bright colors. One end of the rotating column 7 is fixedly connected to a fixing component for positioning and fixing.

[0023] Reference Figure 1 , Figure 4 The fixing component includes a mounting plate 9, which serves as the base for the fixing component and supports all internal parts. The mounting plate 9 is externally fixedly connected to one end of the rotating column 7. The guide plate 8 is internally fixedly connected to a motor 10, which provides the driving force for the fixing action. The drive end of the motor 10 is fixedly connected to a rotating shaft 11, which transmits the torque of the motor 10. One end of the rotating shaft 11 is rotatably connected to the inside of the mounting plate 9. The rotating shaft 11 is externally fixedly connected to a cross plate 12, which converts the rotational motion into linear motion.

[0024] The interior of the cross plate 12 has multiple grooves 13, which are designed to guide the direction of movement. The interior of the mounting plate 9 has multiple limiting blocks 14, which are designed to constrain the movement trajectory and prevent radial deviation. The interior of each groove 13 has a sliding shaft 15, which is designed to directly contact the seabed geology for physical fixation. The exterior of the shaft 15 is slidably connected to the interior of the limiting blocks 14, and the exterior of the multiple shafts 15 is slidably connected to the interior of the mounting plate 9.

[0025] Working principle:

[0026] The working principle and beneficial effects of the triangular guide plate 8 are as follows: its tilt angle is dynamically adjusted through the "motor drive-linkage" transmission chain. The motor 2 drives the rotating arm 3 to rotate, pushes the rotating frame 4 to slide along the rotating arm 6, drives the rotating arm 6 to swing around the rotating axis 5, and makes the rotating column 7 rotate, so as to realize multi-angle pitch and deflection angle adaptation.

[0027] From a fluid dynamics perspective, the hypotenuse of the triangle forms a guide surface, decomposing the lateral water flow impact force into an oblique component. By adjusting the optimal angle between the guide surface and the water flow in real time, the diversion efficiency is maximized. Its beneficial effects are significant: firstly, it dynamically resists current and stabilizes the attitude, adapting to omnidirectional ocean currents including eddies and undercurrents, weakening the lateral impact force, and, in conjunction with the buffer structure, keeping the device's attitude fluctuations within a small range; secondly, attitude self-calibration improves accuracy, with the 8-reaction force of the guide plate assisting in correcting tilt, and the triangular symmetrical structure covering omnidirectional water flow, eliminating the need for multiple guide plates, simplifying design and reducing maintenance difficulty. In summary, this structure, in a collaborative mode, solves the core problem of "attitude drift and signal inaccuracy caused by water flow disturbance" in deep-sea small-pile positioning, laying a stable physical foundation for accurate ultrasonic ranging.

[0028] The working principle of the seabed extension and fixing of the fixed component is as follows: 1. Power triggering and mechanical linkage: Motor 2 10 drives the rotating shaft 11 to rotate the cross plate 12. Under the guidance of the slide groove 13 and the constraint of the limiting block 14, the clamping shaft 15 can only extend and retract around the mounting plate 9; 2. Multi-directional extension action: When the cross plate 12 rotates, the clamping shaft 15 extends outward under the action of centrifugal force and the tilt angle of the slide groove 13. The extension length can be adjusted by motor control; 3. Geological adaptation and anti-disturbance synergy: "piercing fixation" is used for soft mud seabed, and "locking" is used for rocky seabed with serrated tips. At the same time, the guide plate 8 diverts and reduces the lateral load to prevent the clamping shaft 15 from loosening. Its core advantages are: multi-directional adaptation to improve anti-drift capability; intelligent control to adapt to complex geology; and synergy with the guide plate 8 to keep the device stable in multi-knot ocean currents, providing a benchmark for positioning and solving the problem of deep-sea fixing.
