Positioning and adjustment bracket Detailed Implementation

[0030] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0031] like Figure 1 and Figure 2 As shown, the intelligent sonar detection device of this application includes a transducer array 1, a signal transmission harness 2, a housing 3, a support frame 4, and a positioning and adjustment bracket 5. These components work together to achieve high-performance sonar signal transmission and reception, significantly reducing internal signal interference while improving directional resolution.

[0032] The core component of this intelligent sonar detection device is the transducer array 1. The transducer array 1 is installed at the front end of the device and is used to transmit and receive acoustic signals. The elements of the array are distributed at a predetermined uniform spacing, effectively reducing signal interference between elements. To further reduce interference, a sound-absorbing material layer 11 is provided on the surface of the transducer array 1. This measure significantly improves the working environment between elements through sound absorption and noise reduction. Furthermore, the transducer array 1 is divided into several subarrays 12 to form multiple working units. Each subarray contains a fixed number of transducers, thereby optimizing the overall directional resolution and improving detection accuracy.

[0033] Next, the signal transmission harness 2 plays a crucial role as a connecting component, linking the transducer array 1, which is located at the front end and is responsible for sound wave conversion, to the data analysis and processing unit located at the rear. It is arranged behind and connected to the transducer array 1 to ensure that the signal is converted from the physical medium and transmitted to the control center in real time without loss.

[0034] Protecting the entire structure and providing support is the robust and durable outer shell 3 that surrounds the entire intelligent sonar system. This protective shell not only shields the delicate internal components from potential harmful external environmental factors (such as seawater pressure or marine life activity), but also features special design considerations: it has dedicated openings to ensure unobstructed passage of emitted and returned sound waves. This allows sound waves to propagate through the medium while maintaining effective shielding of the internal equipment.

[0035] To ensure the core component, the transducer array 1, is in a suitable and stable state, a robust and reliable internal support system—the support frame 4—is provided. This frame is internally connected to the outer casing 3 and directly correlates to the array's position. This connection method prevents displacement or vibration caused by factors such as water flow during operation, thus enhancing the overall stability of the system and maintaining the necessary space configuration for long-term, efficient operation.

[0036] Finally, there is the component installed at the bottom of the system—the positioning and adjustment bracket 5. This component provides a certain range of angular variation and omnidirectional rotation capability. In other words, users or operators can easily manipulate this equipment to change its orientation or tilt angle to achieve optimal scanning coverage, thereby enabling more flexible and diverse operational goals. This adjustment method is usually achieved by a motor system controlling the actuator to complete the corresponding positional change, and it performs well in certain specific application scenarios such as seabed topography mapping or underwater rescue operations.

[0037] Overall, the aforementioned structural features work together to address the problem of internal signal interference and improve directional resolution: crosstalk is minimized by precisely arranging the spacing between transducers and introducing additional sound-absorbing materials; at the same time, the regional construction method increases pointing accuracy, ultimately making the entire device more sensitive and suitable for efficient detection activities in various complex environmental conditions.

[0038] like Figure 2 As shown, in one embodiment, the transducer elements in the transducer array 1 of the intelligent sonar detection device of this application are arranged with a gradually increasing spacing. The core of this design is that the spacing between the transducer elements gradually increases from the front end to the rear end of the device. This layout can significantly optimize the signal reception angle and effectively reduce signal crosstalk caused by the close proximity of adjacent elements. The implementation of this gradually increasing spacing does not rely on a simple arrangement of a single size or fixed interval, but is carefully designed according to the actual application requirements to ensure optimal performance.

[0039] Specifically, the transducer elements are arranged according to a specific gradient rule, gradually widening from the front of the device. For example, the distance between the elements in the first row is small, and the spacing between each subsequent row increases sequentially. This not only expands the effective coverage of the entire transducer array 1 but also improves the detection accuracy of targets in complex aquatic environments. It is worth noting that since each subarray 12 still maintains a relatively independent functional unit, this change does not affect the overall operating mode.

[0040] For example, a flexible and adjustable support frame 4 can be used to mount the transducer array 1. The support frame 4 has pre-designed spaces of different sizes to secure each transducer element with different spacing requirements. These elements are connected to the back-end processing unit via a customized signal transmission harness 2 to ensure stable signal transmission even with non-uniform spacing. Simultaneously, to further enhance crosstalk immunity, a layer of high-efficiency sound-absorbing material is applied to the surface of the transducer array 1.

[0041] like Figure 2 As shown, in one embodiment, the transducer array 1 of the intelligent sonar detection device of this application employs a multi-layered sound-absorbing material layer 11. This sound-absorbing material layer is located on the surface of the transducer array 1 and is directly bonded to the array. Specifically, this multi-layered sound-absorbing material is composed of different plates of various materials, which are stacked in a specific order according to their respective material properties, thereby achieving effective noise reduction over a wider frequency range. Interference signals between adjacent transducers may be caused by sound wave reflection and residual vibration; the design of the multi-layered composite sound-absorbing material can significantly weaken such effects.

[0042] For example, a rigid sponge board with good low-frequency sound absorption can be selected as the base layer and laid on the transducer surface. Then, a layer of fiber fabric or other lightweight, high-density material with strong high-frequency sound absorption is layered on top to create a frequency-band absorption effect. The sound-absorbing panels are fixed together with adhesive and finally secured to the outside of transducer array 1, ensuring a stable installation position and preventing loosening. This multi-material combination design ensures the matching ability of the sound-absorbing materials to different acoustic characteristics, reducing the impact of external noise or internal crosstalk on system stability.

[0043] like Figure 2 As shown, in one embodiment, an adjustable phase shift controller 13 is provided between each subarray 12 of the transducer array 1 of the intelligent sonar detection device of this application. These controllers 13 are located on the connection path between the subarrays 12 and are connected to the internal circuitry of each subarray 12 to achieve dynamic adjustment of their transmission phase relationship. By adjusting the time delay or electrical angle difference between each subarray 12, the entire system can flexibly optimize its transmission signal characteristics according to environmental changes during operation, improving overall directional resolution and anti-interference capability.

[0044] In this embodiment, the transducer array 1 is specifically designed to be subdivided into several subarrays 12. Each subarray 12 is independently installed and connected to the back-end processing device via a signal harness, and each also has its own phase control unit. This phase control unit can independently regulate the energy form and mode radiated by the corresponding part, thereby achieving more accurate target positioning and filtering of background noise.

[0045] For example, the relative transmission time or phase angle between each subarray 12 can be adjusted by changing the operating state of the controller 13 through software settings. This allows for the reshaping of the beam shape and the selection of the scanning direction without moving the physical location, thereby enhancing the adaptability and flexibility of the sonar system.

[0046] In one embodiment, the signal transmission harness 2 of the intelligent sonar detection device of this application is configured with multiple transmission lines of different types. Each of these different transmission lines corresponds to and is specifically used to transmit acoustic wave signals of a specific type and frequency band. In this way, it can be effectively ensured that acoustic wave signals of different types and frequency bands are separated and processed independently during signal transmission.

[0047] To further enhance system performance and stability, signal transmission harness 2 is mounted on and connected to the back of transducer array 1, thereby reliably receiving and transmitting the acquired acoustic wave information from each transducer to subsequent processing units. Furthermore, this design allows each acoustic wave signal to flow within its own dedicated channel, significantly reducing mutual interference between different signals and ensuring signal transmission quality. Signal transmission harness 2 contains multiple customized internal branches, each optimized for a specific frequency band. For example, some branches are specifically designed to meet the characteristics of low-frequency signals, while others are better suited for high-frequency signal transmission requirements.

[0048] In terms of technical implementation, this feature can be achieved by using multi-core cables. Specifically, each conductor or group of conductors in the multi-core cable is wrapped in an insulation layer and physically separated to avoid electromagnetic interference. Each individually isolated conductor or conductor combination is arranged in the cable according to its corresponding frequency characteristics and signal requirements, thereby ensuring the effective and independent transmission of various signals, and the entire harness structure is tightly arranged and fixed behind the transducer array 1 to maintain mechanical integrity.

[0049] like Figure 5 As shown, in one embodiment, the signal transmission harness 2 of the intelligent sonar detection device of this application is wrapped with an electromagnetic shielding layer 14. This electromagnetic shielding layer 14 is installed on the outside of the signal transmission harness 2 to block external interference noise and improve the quality of the internally transmitted acoustic signals. The electromagnetic shielding layer 14 is mainly made of a material with good conductivity and is tightly bonded to the outer surface of the signal transmission harness 2, effectively preventing external electromagnetic waves from entering the harness. This structure ensures the integrity of the acoustic signals and stable operation in complex electromagnetic environments.

[0050] For example, the electromagnetic shielding layer 14 can be made of materials such as metal braided mesh or metal foil, and is tightly attached to the outside of the signal transmission harness 2 by mechanical extrusion, adhesive, or other fixing methods. Simultaneously, to enhance the shielding effect, an additional layer of insulating protective material can be wrapped around the electromagnetic shielding layer 14 to prevent physical damage and maintain its long-term effectiveness. Specifically, the shielding layer is continuously arranged along the entire length of the signal transmission harness 2, extending from the rear end of the transducer array 1 to near the interface of the rear processing unit, forming a unified layout with the overall structure to ensure full protection during signal transmission.

[0051] like Figure 1As shown, in one embodiment, the front end of the housing 3 of the intelligent sonar detection device of this application adopts an acoustic lens structure 15. This structure is located at the opening of the housing 3 and is adjacent to the front of the transducer array 1. The acoustic lens structure 15 is composed of multiple layers of materials with different acoustic properties. Its material and thickness distribution are optimized to uniformly focus or diverge sound waves. The acoustic lens is fixed to the inside of the housing 3 by a specific mounting component to ensure that the distance between it and the transducer array 1 remains constant, while ensuring that it is precisely aligned with the edge of the opening of the housing 3.

[0052] This design allows sound waves to reduce propagation deviations caused by non-uniformity when penetrating a medium, improving detection accuracy. Specifically, the curved shape of the acoustic lens is customized according to the required focusing range and is connected to the housing 3 by bonding or other fastening methods. For example, polymer materials with different sound velocities can be selected to fabricate different areas of the lens, achieving gradual modulation of the sound waves. Technical implementation of this feature may include pre-testing the lens's performance in a simulated environment and then adjusting its geometry and material composition until the desired design goals are achieved.

[0053] like Figure 2 As shown, in one embodiment, a shock-absorbing rubber 16 is fixed to the bottom end of the support frame 4 of the intelligent sonar detection device of this application to adapt to the external vibration environment and protect the internal components. Specifically, the shock-absorbing rubber 16 is installed on the bottom plane of the support frame 4 and is connected to the support frame 4 by bonding, mechanical fixing or composite structure, playing a role in buffering external impact and reducing noise transmission. This design can avoid the displacement or damage of internal components caused by external environmental vibration, while suppressing additional noise interference caused by vibration. As a key component, the shock-absorbing rubber 16 itself has the characteristics of flexible material, and its thickness and shape can be customized according to actual needs, ensuring stability and reliability under long-term operating conditions.

[0054] For example, this feature can be achieved by adhering one or more layers of flexible damping rubber 16 to the bottom of the support frame 4. Specifically, a rubber material with a high damping coefficient is selected to meet the vibration reduction requirements, and then it is tightly assembled to the corresponding position of the support frame 4 using adhesives or locking components. This installation method, combined with the material properties, can enhance the stability and quietness of the device without changing the overall structural design.

[0055] like Figure 2 and Figure 4As shown, in one embodiment, a cooling water channel 17 is provided within the support frame 4 of the intelligent sonar detection device of this application to meet heat dissipation requirements. Specifically, the support frame 4, as a key load-bearing structure, is located inside and connected to the outer shell 3, and is used to fix the position of the transducer array 1. By installing the cooling water channel 17 inside, it is ensured that the heat generated during long-term operation due to signal transmission, component processing, and other processes can be effectively removed. The cooling water channel 17 provides continuous and stable heat transfer capability through a flow circulation system, avoiding the impact of abnormal local temperature rise on the transducer array 1 and its related components.

[0056] The supporting frame 4 serves as the main load-bearing component and positioning reference surface in the entire device structure, and its internal design includes a fluid channel structure that connects to the external water pump. For example, the inlet and outlet ports of the cooling water channel 17 can be located at both ends of the frame, and precision machining ensures a reasonable distribution of the internal water channel shape, thereby covering key heat-generating areas. In addition, the design of the cooling water channel 17 must also consider the matching requirements of material thermal conductivity and overall device sealing.

[0057] Specifically, the cooling water channels 17 within the support frame 4 consist of multiple layers of pipes, forming a complete closed-loop system through welding or embedded assembly. For example, corrosion-resistant materials are processed into pipes with a predetermined trajectory and embedded into the main body of the support frame 4, then connected to an external cooling system via joints to form a circulating water flow system. This installation and connection method ensures heat dissipation performance while maintaining the overall compactness of the entire device.

[0058] like Figure 3 As shown, in one embodiment, the positioning adjustment bracket 5 of the intelligent sonar detection device of this application employs a flexible universal joint structure 18, the purpose of which is to allow precise fine-tuning in three-dimensional directions and to achieve flexible angle locking. This flexible universal joint structure 18 ensures that the device can adapt to the operational needs of various complex environments. This flexible universal joint consists of multiple movable joints, each with a high-precision damping device to provide smooth and stable directional adjustment performance. The tight connection between these components not only gives the device the required flexibility but also ensures reliability and stability during long-term use.

[0059] The positioning and adjustment bracket 5 is installed at the bottom of the housing 3 and fixed to the support frame 4 by a sturdy flange or other suitable connectors. This allows it to be separated from the external mounting structure and operate relatively independently, ensuring the overall structural stability of the sonar system while retaining sufficient adjustability. Specifically, to achieve precise fine-tuning in three dimensions, each movable joint incorporates a micro-drive element and encoder module to accurately control angle changes and respond instantly to operator commands, enabling diverse adjustment modes such as stepless continuous rotation or stepped limit locking.

[0060] For example, this feature can be achieved by integrating precision motors, electro-hydraulic servo mechanisms, or other small actuators, and by setting corresponding sensors inside the flexible universal joint to monitor the position and attitude information of each joint and connecting them to the central processor to design a feedback closed-loop control mechanism, thereby ensuring that each orientation adjustment meets the requirements of the user-set parameters.

[0061] like Figure 2 As shown, in one embodiment, the subarray 12 of the intelligent sonar detection device of this application includes an independent data processor 19 for real-time monitoring and correction of the spatial characteristics of the data collected by each sensor unit. The data processor 19 is embedded within or adjacent to the location of the subarray 12 to ensure optimal processing speed and efficiency. In this configuration, each subarray 12 and its corresponding independent data processor 19 logically form a closed and efficient microsystem capable of rapidly analyzing, processing, and adjusting signals received from its own transducer elements.

[0062] Specifically, this structure facilitates more precise spatial characteristic correction, such as time delay and amplitude adjustment, and reduces distortion or noise amplification caused by transmission errors. These independent data processors 19 are also equipped with sophisticated computational circuits and algorithm storage modules, enabling advanced data analysis and adaptive adjustment functions to further optimize the overall performance of the device. Simultaneously, the connections between the internal components of each subarray 12 are tightly designed to ensure that signals are transmitted to their respective independent data processors 19 within extremely short delay times. Furthermore, to enhance system reliability, all connection points are specially reinforced and possess resistance to environmental interference.

[0063] For example, by integrating microelectronics technology, a high-density integrated circuit board is embedded within the sub-array 12 and directly connected to each transducer element via ultra-low delay wires. This not only achieves efficient information exchange path construction but also utilizes onboard processing units to perform preliminary signal preprocessing before sending the signals to the central control unit for final processing and output. In this way, distributed information processing is achieved without affecting the overall architecture's compactness, while also ensuring system stability and flexibility.

[0064] In actual operation, when this device is in use, the transducer array 1 emits acoustic signals and receives the returned acoustic signals to realize the detection and positioning functions of the target object. The signal transmission harness 2 transmits the received acoustic signals to the back-end processing unit for analysis and processing. The housing 3 provides protection for the entire device and allows the acoustic waves to enter and exit smoothly to ensure effective signal transmission. The support frame 4 is used to stabilize and fix the position of the transducer array 1 to prevent the components from shifting due to external factors. The positioning adjustment bracket 5 can adjust the overall direction and angle of the device to adapt to different detection needs. At the same time, the sound-absorbing material layer 11 on the surface of the transducer array 1 can reduce signal interference between adjacent components, while the design of dividing it into multiple sub-arrays 12 helps to improve the overall directional resolution of the device.
