Description

Technical Field

[0001] The present invention relates to the technical field of ocean wind speed detection. Specifically, it relates to a low-cost ocean wind speed and direction sensor mechanism based on noise inversion. Background Art

[0002] Wind, as an important ocean meteorological element, is of crucial significance for studying the changes in ocean climate and the generation of waves. When operating at sea, it is necessary to identify the direction and speed. There are usually two methods for traditional air flow direction and speed measurement: porous probe measurement and hot wire / hot film method measurement. The common types of wind speed and direction sensors on the market currently include mechanical wind speed and direction sensors, ultrasonic wind speed and direction sensors, and optoelectronic wind speed and direction sensors. When using the above sensors for unattended operation on the sea surface, there are the following problems: limited monitoring range, limited real-time response, and low equipment stability, etc.

[0003] Therefore, a low-cost ocean wind speed and direction sensor mechanism based on noise inversion is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The present invention aims to provide a low-cost ocean wind speed and direction sensor mechanism based on noise inversion to solve or improve at least one of the above technical problems.

[0005] In view of this, the first aspect of the present invention is to provide a low-cost ocean wind speed and direction sensor mechanism based on noise inversion.

[0006] The first aspect of the present invention provides a low-cost ocean wind speed and direction sensor mechanism based on noise inversion, including: a first detection part, arranged above the sea surface; the first detection part includes a first sensor, and the first sensor is used to obtain the first wind speed data of the ocean wind on the sea surface; a second detection part, floating on the sea surface, and the second detection part is connected to the first detection part through a connecting rod; the second detection part includes a plurality of second sensors, and the second sensors are arranged along the circumferential direction of the connecting rod; wherein, one end of the connecting rod far from the first detection part is elastically connected to the inside of the second detection part, so as to drive the connecting rod to swing when the ocean wind flows through the first detection part, and obtain the second wind speed data and direction data of the ocean wind through the cooperation of the connecting rod and the second sensors.

[0007] In any of the above technical solutions, the second detection part further includes a second detection ball and an internal floating body, and the outer wall of the internal floating body is slidably connected to the inner wall of the second detection ball; the middle part of the internal floating body is recessed away from the first detection part and forms an inner groove; one end of the connecting rod located inside the second detection ball and the second sensors are respectively connected to the inner wall of the inner groove.

[0008] In any of the above technical solutions, a hollow cavity is formed between the outer wall of the inner floating body facing away from the inner groove and the inner wall of the second detection ball.

[0009] In any of the above technical solutions, the hollow cavity is filled with a first counterweight. The first counterweight is circumferentially wrapped around the center of the inner floating body and is eccentrically arranged with the second detection ball to block the rotation of the inner floating body when the connecting rod swings.

[0010] In any of the above technical solutions, each of the second sensors includes a piezoelectric sheet disposed in the inner groove. A first gap is formed between the piezoelectric sheet and the outer wall of the connecting rod, and all the first gaps form an annular cavity along the circumference of the connecting rod. The annular cavity is used for the first detection part to drive the connecting rod to swing.

[0011] In any of the above technical solutions, when the connecting rod applies pressure to at least one of the piezoelectric sheets, the piezoelectric sheet obtains the pressure data applied by the connecting rod. And the pressure data is used to generate the second wind speed data and the wind direction data.

[0012] In any of the above technical solutions, the first detection part further includes a first detection ball connected to the connecting rod. The first sensor is installed inside the first detection ball. The first sensor is a sound sensor, and the sound sensor is used to obtain the noise data when the ocean wind flows through the first detection ball. The noise data is used to generate the first wind speed data and correct the second wind speed data.

[0013] In any of the above technical solutions, all the piezoelectric sheets are connected to the inner wall of the inner groove through a support part, and the connecting rod is connected to the inner wall of the inner groove through an elastic part. The support part includes a connecting ring fixedly assembled with the piezoelectric sheet, and the connecting ring is located between the piezoelectric sheet and the elastic part.

[0014] In any of the above technical solutions, the support part further includes a plurality of support rods for connecting the connecting ring and the inner groove. All the support rods are telescopically arranged, and at least one of the support rods is an electric telescopic rod. The electric telescopic rod adjusts the axially corresponding position of the annular cavity and the connecting rod by extending its length.

[0015] In any of the above technical solutions, the ocean wind speed and direction sensor mechanism further includes a controller, and the controller is installed on the inner wall of the inner groove. The controller is respectively connected to the first sensor and the electric telescopic rod to adjust the extension length of the electric telescopic rod through the first wind speed data.

[0016] Advantages of the present invention compared with the prior art:

[0017] By arranging two interconnected first detection parts and second detection parts on the sea surface, the solution of the present invention can adopt a wider range of detection means to measure wind speed and wind direction, and significantly improves the coverage range compared with a single sensor position.

[0018] The design of the first sensor and the second sensor ensures real-time data collection from multiple directions and positions, and quickly responds to changes in the wind in the environment. This layout enables the system to capture real-time changes in the wind more sensitively and quickly.

[0019] Using an elastic connection between the second detection part and the connecting rod reduces mechanical wear and sensitivity to bad weather. The elastic connection can absorb part of the impact caused by movement, reducing the risk of mechanical damage caused by high wind speed.

[0020] Omnidirectional and multi-point wind speed and wind direction monitoring are realized, providing more comprehensive and detailed wind field data. Due to the swing mechanism and the configuration of multi-point sensors, the characteristics of the wind can be measured and analyzed more accurately, improving the accuracy and reliability of the data. The elastic connection design reduces mechanical stress and extends the service life of the equipment, especially under frequently changing marine climate conditions.

Detailed implementation manners

[0028] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0029] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0030] Please refer to Figures 1 - 3 , and a low-cost ocean wind speed and direction sensor mechanism based on noise inversion in some embodiments of the present invention will be described below.

[0031] An embodiment of the first aspect of the present invention provides a low-cost ocean wind speed and direction sensor mechanism based on noise inversion. In some embodiments of the present invention, as Figures 1 - 3 shown, the ocean wind speed and direction sensor mechanism includes:

[0032] A first detection unit, arranged above the sea surface; the first detection unit includes a first sensor, and the first sensor is used to obtain the first wind speed data of the ocean wind on the sea surface.

[0033] A second detection unit, floating on the sea surface, and the second detection unit is connected to the first detection unit through a connecting rod 9; the second detection unit includes a plurality of second sensors, and the second sensors are arranged circumferentially along the connecting rod 9.

[0034] Wherein, one end of the connecting rod 9 far from the first detection unit is elastically connected to the inside of the second detection unit, so as to drive the connecting rod 9 to swing when the ocean wind flows through the first detection unit, and obtain the second wind speed data and wind direction data of the ocean wind through the cooperation of the connecting rod 9 and the second sensors.

[0035] For the low-cost ocean wind speed and direction sensor mechanism provided by the present invention, the main function of the first detection unit is to monitor and record the wind speed of the ocean wind on the sea surface. This part is usually arranged above the sea surface to ensure direct contact with the ocean wind, so as to obtain accurate wind speed data. These data are crucial for fields such as meteorological analysis, ocean research, navigation safety and climate monitoring. The first sensor is the core of the first detection unit and is responsible for capturing and converting the information of the sea surface wind speed.

[0036] The first sensor can measure the wind speed by sensing the pressure changes caused by air flow or by using other meteorological measurement techniques (such as ultrasonic, Pitot tube, etc.). Depending on the type of sensor, its specific measurement principle also varies: For a pressure sensor, it uses the pressure difference to determine the wind speed. The greater the wind speed, the greater the sensed pressure difference; For an ultrasonic sensor, it determines the wind speed by measuring the change in the propagation speed of sound waves in the air. The propagation time of ultrasonic waves in the wind varies with the wind speed, and the wind speed can be accurately calculated through this change; For a Pitot tube, it measures the pressure change caused by the wind speed entering the tube and uses this data to calculate the wind speed; When the first sensor captures the wind speed data, these data are usually converted into electrical signals and sent to the data processing unit. The data processing unit analyzes and processes the signals, converts them into available wind speed data, and these data can then be displayed on the monitoring system or transmitted to a remote database for further analysis and storage. The final wind speed data can be used for immediate weather updates or as part of long-term climate monitoring.

[0037] The design of the second detection unit aims to provide more comprehensive and detailed sea surface wind speed and wind direction data through multiple second sensors circumferentially arranged along the connecting rod 9; The second detection unit is designed to float on the sea surface, which enables it to directly interact with the sea surface wind and receive wind data from multiple angles; By evenly arranging multiple second sensors around the connecting rod 9, the second detection unit can capture wind speed and wind direction information from different directions, contributing to a comprehensive assessment of the wind field characteristics; The second detection unit is connected to the first detection unit through the connecting rod 9, enabling the data of the two parts to be mutually verified and supplemented, improving the accuracy and reliability of the overall measurement.

[0038] The second sensors determine the wind speed and direction by physical or acoustic methods. These sensors may use techniques similar to those of the first detection unit (such as pressure difference, ultrasonic, hot wire, etc.), or adopt other techniques specific to their arrangement and function; The circumferential arrangement of the sensors along the connecting rod 9 allows for the capture of the dynamics of the wind from a full 360-degree range, which is a very useful characteristic for evaluating complex wind fields; The data collected from the multiple sensors of the second detection unit are synchronized and transmitted to the central data processing unit. The data processing unit will comprehensively analyze the data of each sensor and use algorithms to integrate and correct the data to provide accurate wind speed and wind direction readings; The configuration of the second detection unit connected to the first detection unit through the connecting rod 9 may also enable it to dynamically respond to changes in the force and direction of the wind. For example, the wind force may cause a slight swing of the connecting rod 9, and this swing is captured by the sensors and converted into wind direction data.

[0039] The elastic connection of the second detection part enables the connecting rod 9 to swing under the action of wind force. This kind of swing can not only capture the wind speed, but also directly reflect the wind direction through the swing direction and amplitude; by measuring the wind parameters through dynamic swing, the limitations that may be brought by fixed measurement points can be reduced, and more comprehensive wind field information can be provided.

[0040] When ocean current flows through the first detection part, the force of the wind is captured by the first sensor, and the connecting rod 9 is caused to receive a driving force. Since the connecting rod 9 is connected to the inside of the second detection part through an elastic element (such as a spring), this driving force will be converted into the swing of the connecting rod 9. The swing amplitude and frequency of the connecting rod 9 will reflect the wind strength and stability, and the swing direction provides wind direction information; the second sensors arranged circumferentially along the connecting rod 9 measure and calculate the wind speed and wind direction according to the swing angle and speed change of the connecting rod 9. The second sensors may use angle encoders, gyroscopes or other angle sensing devices to accurately capture the swing data of the connecting rod 9; all the sensor data of the second detection part are synchronized and sent to the central data processing unit. The data processing unit integrates the data from the first detection part and the second detection part through algorithms to provide more accurate and comprehensive wind speed and wind direction information.

[0041] In summary, the design using noise inversion technology reduces the dependence on high-end sensors and complex mechanical components, thus significantly reducing the manufacturing and maintenance costs. This makes this sensor system more economical and easier to be deployed on a large scale; by combining the data of the first detection part and the second detection part, highly accurate and comprehensive wind speed and wind direction measurements can be provided. The elastic connection of the second detection part and the design of the connecting rod 9 allow for accurate capture of the dynamic changes of the wind, thereby improving the sensitivity and response speed of the overall measurement; the sensor mechanism design takes into account the challenges of the ocean environment, such as salt spray corrosion, water surface changes and other adverse weather conditions. The floating design and the internal elastic connection ensure the stability and durability of the device in a complex environment; the multiple second sensors arranged circumferentially along the connecting rod 9 of the second detection part provide 360-degree wind direction monitoring ability, which is very important for comprehensively understanding and analyzing the characteristics of the wind field; the technology relied on is mature and reliable, and is easy to be deployed in ocean areas far from the shore. At the same time, the low maintenance requirements reduce the complexity and cost of long-term operation.

[0042] In any of the above embodiments, the second detection part further includes a second detection ball 4 and an internal floating body 5. The outer wall of the internal floating body 5 is slidably connected to the inner wall of the second detection ball 4 to avoid or weaken the synchronous driving of the internal floating body 5 to follow the swing when the second detection ball 4 is driven by external sea waves to swing.

[0043] The middle part of the internal floating body 5 is recessed away from the first detection part to form an inner groove. By recessing axially downward along the connecting rod 9, the center of gravity of the internal floating body 5 in the second detection ball 4 can be effectively reduced; one end of the connecting rod 9 located inside the second detection ball 4 and the second sensor are respectively connected to the inner wall of the inner groove to immediately detect the swing of the connecting rod 9 caused by the action of ocean wind.

[0044] In this embodiment, the main purpose of the design of the second detection ball 4 is to keep the second sensor stable and accurately measure the wind speed and direction even under the action of violent sea waves and wind; by reducing the direct impact of external sea waves on the internal floating body 5, the system can avoid measurement errors introduced by the swaying of the internal floating body 5 with the waves, ensuring the accuracy and reliability of the data.

[0045] The second detection ball 4 is designed as a sturdy outer shell that can float on the water surface to protect the multiple second sensors and electronic devices inside from seawater erosion and physical damage. The internal floating body 5 is installed inside the second detection ball 4, and its design enables the outer wall to slide on the inner wall of the second detection ball 4. This sliding connection allows the internal floating body 5 to move freely within a certain range but not completely break away from the outer shell; when external sea waves act on the second detection ball 4, the outer shell may sway or displace. Since the internal floating body 5 is slidably connected to the outer shell, this design allows the internal floating body 5 to maintain relative position stability even when the outer shell moves or tilts due to wave action. This relatively independent internal structure significantly reduces the influence of environmental factors on the measurement accuracy of the second sensor; the design of the internal floating body 5 not only provides physical protection but also plays a role in shock absorption and buffering. In the marine environment, shock absorption is a key factor in maintaining data accuracy; protecting the internal second sensor from the harsh marine environment, such as brine corrosion and marine organism attachment, enables the second sensor to operate in a relatively stable environment, thereby improving the accuracy and repeatability of the measurement data.

[0046] The inner groove formed by the downward recess of the middle part of the internal floating body 5 can help concentrate the mass of the floating body, reduce unnecessary sway caused by sea surface fluctuations, and enhance the overall stability; the connecting rod 9 and its associated second sensor are connected to the inner wall of the inner groove, and this arrangement makes the second sensor closer to the center of mass of the device, improving the detection accuracy of the swing.

[0047] The groove formed by the depression in the middle of the internal floating body 5 is to lower the center of mass of the system, reduce the influence of external environmental changes on the measuring device, and make it more stable; one end of the connecting rod 9 is fixed to the inner wall of the inner groove inside the second detection ball 4. Such a design enables the swing of the connecting rod 9 under the action of wind to be directly transmitted to the second sensor; when the ocean wind blows the first detection part, this power will be transmitted to the second detection part through the connecting rod 9. Since the connecting rod 9 is directly connected to the inner wall of the inner groove, any swing caused by the wind will cause the connecting rod 9 to move inside the inner groove, and this swing is immediately captured by the second sensor. Since the second sensor is installed on the connecting rod 9, close to the position of the inner groove, it can measure and feedback the magnitude and direction of the swing very precisely.

[0048] In any of the above embodiments, a hollow cavity 401 is formed between the outer wall of the internal floating body 5 facing away from the inner groove and the inner wall of the second detection ball 4, and the hollow cavity 401 is located on the circumferential outer periphery of the internal floating body 5. Through the spaced arrangement of the hollow cavity 401, when the seawater with temperature changes affects the thermal expansion and contraction of the second detection ball 4 and the internal floating body 5, dimensional redundancy can be carried out so that the internal floating body 5 can normally slide or rotate relative to the second detection ball 4.

[0049] In this embodiment, the hollow cavity 401 provides additional space, allowing the internal floating body 5 to maintain normal sliding or rotation during thermal expansion and contraction caused by temperature, avoiding direct contact and possible jamming; the hollow cavity 401 can not only cope with temperature changes, but also absorb and buffer vibrations or impacts in the marine environment, protecting the internal structure from damage; by forming the hollow cavity 401 between the internal floating body 5 and the second detection ball 4, hard contact can be reduced, the service life of the device can be extended and the reliability can be improved.

[0050] The internal floating body 5 is designed around the central axis, has a shape extending outwards, is formed in the middle at the inner groove, and the hollow cavity 401 is located between the outer wall of the internal floating body 5 and the inner wall of the second detection ball 4, surrounding at least part of the area of the internal floating body 5 along the circumference; in the marine environment, temperature changes frequently, especially in deep sea or extreme climate conditions. The second detection ball 4 and the internal floating body 5 will experience thermal expansion and contraction due to material properties. The hollow cavity 401 allows the second detection ball 4 and the internal floating body 5 to freely expand or contract at different temperatures without their structures interfering with each other or getting stuck; the design of the hollow cavity 401 ensures that even in the case of extreme temperature changes, the internal floating body 5 can still slide or slightly rotate inside the second detection ball 4, ensuring the normal operation of the second sensor. This free movement helps to maintain the accuracy of the second sensor, especially when the sensor relies on precise position and angle to measure wind speed and direction; under the influence of ocean wind or waves, the second detection ball 4 may move or swing. The presence of the hollow cavity 401 reduces the possibility of this external power being directly transmitted to the internal floating body 5, thereby reducing the risk of misoperation and damage.

[0051] In any of the above embodiments, the interior of the hollow cavity 401 is filled with a first counterweight. The center of the inner floating body 5 is circumferentially wrapped by the first counterweight and is eccentrically arranged with respect to the second detection ball 4 so as to block the rotation of the inner floating body 5 when the connecting rod 9 swings. The arrangement of the first counterweight can, on the one hand, increase the counterweight at the bottom to contribute to the overall stability, and on the other hand, can avoid or reduce the steady-state disturbance of the inner floating body 5 caused by the swing of the connecting rod 9, thereby improving the accuracy of detecting the swing of the connecting rod 9.

[0052] In this embodiment, by adding a counterweight at the bottom, the stability of the entire second detection ball 4 is enhanced. Especially when affected by wind and waves on the sea surface, it can better maintain its balance and positioning; through its eccentric arrangement, the first counterweight effectively blocks and reduces the direct influence of the swing of the connecting rod 9 on the inner floating body 5, and reduces the influence of external disturbances on the steady state of the inner floating body 5.

[0053] The center of the inner floating body 5 is circumferentially wrapped by the first counterweight, but is eccentrically arranged with respect to the second detection ball 4. This design enables the counterweight to not only increase the overall downward force, but also help adjust and control the dynamic behavior of the inner floating body 5 through the strategic layout of its position; the first counterweight is filled inside the hollow cavity 401 and arranged around the inner floating body 5. Such filling increases the density of the overall structure and lowers the center of gravity, contributing to the stability of the entire device; when the connecting rod 9 swings due to the action of wind, the eccentric arrangement of the first counterweight can effectively block the excessive rotation or swing of the inner floating body 5. This is achieved by increasing static friction or creating a damping effect, relying on the physical contact between the first counterweight and the inner floating body 5 and the inner wall of the second detection ball 4; by restricting the irrelevant movement of the inner floating body 5, the first counterweight ensures that all the dynamics transmitted by the connecting rod 9 are direct responses to the wind swing, rather than non-target actions caused by sea waves or other environmental factors. This makes the swing data captured by the connecting rod 9 and the second sensor more accurate, directly reflecting the influence of the wind; since the movement of the inner floating body 5 is effectively controlled, the sensor can more accurately detect the swing of the connecting rod 9, thereby improving the quality and reliability of the data. When processing these data, one can be more confident that it reflects the real environmental conditions, rather than misreading due to unstable internal structure.

[0054] Furthermore, the first counterweight can be a liquid and has a density less than that of seawater, while filling the interior of the hollow cavity 401 and providing buoyancy. The liquid can be: mineral oil, silicone oil or vegetable oil.

[0055] As described above, using a liquid with a density less than that of seawater as a counterweight can provide the necessary buoyancy while increasing the sinking weight, which helps to adjust the floating and sinking balance of the overall device; the liquid counterweight can flexibly fill the interior of the hollow cavity 401, adapting to the shape and volume changes of the internal space, which is particularly effective for dimensional changes caused by temperature.

[0056] Since the density of the liquid is less than that of seawater, it can provide a certain buoyancy for the second detection sphere 4, which helps to maintain the stability of the device on the water surface and an appropriate floating and sinking depth; at the same time, since the liquid itself has weight, it can still be used as a counterweight to help maintain the bottom center of gravity of the device and enhance stability; the liquid has good adaptability during thermal expansion and contraction, and it can flow freely to adapt to the shape and volume changes of the internal container. When the temperature change causes the materials of the second detection sphere 4 and the internal floating body 5 to expand or contract, the liquid can naturally adjust its distribution to avoid exerting pressure on the internal structure. This self-regulating property helps to maintain the freedom of movement of the internal mechanical components and prevent damage or functional failure caused by excessive pressure; the fluidity of the liquid allows it to provide a liquid buffer layer between the internal floating body 5 and the second detection sphere 4. This can effectively reduce mechanical friction and resistance, especially when the internal floating body 5 needs to make minor adjustments or rotations relative to the second detection sphere 4. This liquid buffer layer can also absorb part of the external vibration or impact and reduce the potential impact of these factors on the accuracy of the second sensor; when the connecting rod 9 swings under the influence of wind, the fluidity of the liquid counterweight can provide a more sensitive response dynamics. It allows the internal floating body 5 to adjust its position more smoothly to adapt to the dynamic changes of the connecting rod 9, improving the reaction speed and measurement accuracy of the entire system to wind changes.

[0057] Furthermore, a second counterweight 8 is installed on the bottom outer wall of the second detection sphere 4 through a connecting chain 7.

[0058] As described above, the second counterweight 8 increases the total weight of the second detection sphere 4, especially at its bottom, which helps to lower the center of gravity of the device and make it more stable in the marine environment; reduce the sway caused by wind and waves: the lowering of the center of gravity and the increased mass help to reduce the sway caused by wind or waves and improve the measurement accuracy and reliability of the measuring device; the heavier bottom can reduce the influence of ocean currents on the position of the second detection sphere 4 and maintain its relatively fixed monitoring position.

[0059] By adding a second counterweight 8 at the bottom, the center of gravity of the second detection ball 4 is effectively lowered. A lower center of gravity can make the entire structure more stable in water. Especially when affected by upper-layer wind or water flow disturbances, the lowering of the center of gravity helps to keep the device upright and avoid tipping over or excessive swaying in a relatively rough ocean environment. The connecting chain 7 allows the second counterweight 8 to move freely within a certain range, which can increase the stability of the system without sacrificing flexibility. Under the action of sea waves or wind, the dynamic adjustment of the second counterweight 8 can help the entire device maintain balance and reduce unnecessary swaying. This freely mounted design allows the second counterweight 8 to adjust its position as needed to maximize resistance to unstable swaying caused by external forces. By reducing the overall swaying of the device, it can ensure that the internal second sensor records data more accurately. When the device remains relatively stationary, the data recorded by the second sensor will more accurately reflect the actual environmental conditions rather than the dynamics of the device itself. The heavier second counterweight 8 also helps to anchor the device in a specific area. This is crucial for long-term monitoring or data collection in a specific area and can prevent the device from being carried away from its original position by ocean currents or strong winds.

[0060] In any of the above embodiments, the second sensor is a piezoelectric sensor 3. Each piezoelectric sensor 3 includes a piezoelectric sheet disposed in the inner groove. A first gap is formed between the piezoelectric sheet and the outer wall of the connecting rod 9, and all the first gaps form an annular cavity along the circumferential direction of the connecting rod 9. The annular cavity formed by the first gaps can make a space between the piezoelectric sheet and the connecting rod 9, avoiding the formation of detection results due to slight swaying, reducing the detection times of non-significant ocean winds, and reducing the power consumption inside the device.

[0061] The annular cavity is used for the first detection part to drive the connecting rod 9 to swing, and when the connecting rod 9 crosses the annular cavity and contacts the piezoelectric sheet and applies a force, the wind detection will be triggered.

[0062] In this embodiment, the piezoelectric sheet can very sensitively detect the pressure change caused by the wind acting on the connecting rod 9, and this change is used to calculate the wind speed and direction. By setting the annular cavity formed by the first gaps, a space is formed between the piezoelectric sheet and the connecting rod 9, which reduces the response to small or non-significant winds, thereby reducing the number of false triggers and the overall energy consumption. The space in the design helps to prevent false measurements caused by non-target movements of the connecting rod 9 (such as swaying caused by sea waves).

[0063] A piezoelectric sheet is a material that can convert mechanical pressure into an electrical signal. When the connecting rod 9 moves or bends due to the action of wind force, this force acts on the piezoelectric sheet, and the piezoelectric sheet will generate a voltage change. This change is captured by the sensor and converted into data on wind speed and direction; the first gap ensures a certain physical distance between the piezoelectric sheet and the connecting rod 9, and this distance is sufficient to prevent the piezoelectric sheet from being activated by every small swing of the connecting rod 9. Only when the swing reaches a certain strength and range will the piezoelectric sheet sense sufficient pressure change to react; all the first gaps combine into an annular cavity along the circumferential direction of the connecting rod 9. This structural design increases the overall balance and the response ability to environmental changes. The presence of the annular cavity ensures that the piezoelectric sheets can be evenly arranged around the connecting rod 9, thus comprehensively capturing the influence of wind force on the connecting rod 9; due to the existence of the first gap, the system can filter out those insignificant wind force effects and only respond to wind forces of sufficient intensity. This reduces frequent data recording and transmission, thereby reducing the energy consumption of the device; in the absence of significant wind force, the system will not generate unnecessary data processing and power consumption, which helps to improve the overall system efficiency and endurance.

[0064] The annular cavity provides the necessary physical space for the connecting rod 9 to swing freely when subjected to wind force without immediately touching the piezoelectric sheet, avoiding reaction to minor or insignificant wind forces; the size of the annular cavity is designed such that only when the connecting rod 9 swings to a certain amplitude can it contact and apply force to the piezoelectric sheet, thus triggering wind force detection. This design essentially sets a natural "threshold" for the system, and only wind forces of sufficient intensity can trigger a reaction, reducing the false trigger rate.

[0065] When wind force acts on the first detection part, this force is transmitted through the connecting rod 9, causing the connecting rod 9 to swing. The annular cavity provides enough space for the connecting rod 9 to swing freely without touching the piezoelectric sheet before reaching the threshold. This design allows the connecting rod 9 to move within a certain range without triggering any reaction from the second sensor, which is crucial for avoiding data recording caused by slight wind force or other non-target interferences (such as waves or hull movement); only when the swing of the connecting rod 9 is large enough so that one end of it crosses the annular cavity and touches the piezoelectric sheet will the piezoelectric sheet be subjected to sufficient force to generate an electrical signal. The application of this force represents a strong enough wind force that needs to be recorded and analyzed by the system. The pressure sensed by the piezoelectric sheet is converted into an electrical signal, and then these electrical signals are transmitted to the data processing unit for calculation of wind speed and direction; through this mechanism, the system can more accurately measure significantly meaningful wind force events, reducing unnecessary data processing caused by environmental noise or small swings. Once triggered, the electrical signals generated by the piezoelectric sheet will be immediately analyzed to ensure the real-time and accuracy of the data, thus providing reliable information for meteorological monitoring.

[0066] In any of the above embodiments, when the connecting rod 9 applies pressure to at least one piezoelectric sheet, the piezoelectric sheet acquires the pressure data applied by the connecting rod 9.

[0067] The pressure data is used to generate the second wind speed data and wind direction data. By detecting different pressure data with the piezoelectric sheet, the direction of the ocean wind can be judged, and the wind force magnitude in the current direction can be summarized based on the specific pressure data.

[0068] In this embodiment, the piezoelectric sheet directly measures the pressure applied by the connecting rod 9. This pressure is usually caused by the swing of the connecting rod 9 due to the wind force. The response of the piezoelectric sheet is used to calculate the intensity and direction of the wind force; the piezoelectric sheet converts the detected physical pressure into an electrical signal, and these electrical signals can be quantified and used for further data processing and analysis.

[0069] The piezoelectric sheet works based on the piezoelectric effect, which is a property of certain materials (such as quartz, certain ceramics, and plastics) that can generate a voltage when subjected to mechanical stress. When these piezoelectric materials are compressed or stretched, the change in their internal structure causes a redistribution of charges, resulting in the generation of a voltage. In the system, when the connecting rod 9 swings and contacts the piezoelectric sheet, the applied force presses the piezoelectric sheet, causing a change in its voltage; the electrical signal generated by the piezoelectric sheet after sensing the pressure is proportional to the applied force. These signals are transmitted to the data processing unit of the system, and the data processing unit converts these electrical signals into digital data, which reflects the intensity of the pressure and is thus used to calculate the wind speed and direction; the data processing unit analyzes the received data to judge the behavioral characteristics of the wind, such as the speed of the wind and the change in the wind direction. These analysis results are very important for weather forecasting, environmental monitoring, and related decision-making. The system also includes software tools that can visualize the data and provide a user-friendly interface to display information such as wind speed and wind direction; the system design can include threshold setting, and only when the applied pressure exceeds a preset threshold does the piezoelectric sheet respond, which helps to reduce the influence of background noise and minor interference. In this way, the system ensures that only significant wind force events are recorded and analyzed, improving the overall monitoring efficiency and accuracy.

[0070] By detecting the pressure applied by the connecting rod 9 to the piezoelectric sheet in different directions, the direction of the wind can be judged. Different piezoelectric sheets correspond to different faces of the connecting rod 9. Therefore, the specific blowing direction of the wind can be determined by comparing the pressures received by these piezoelectric sheets; the magnitude of the pressure is proportional to the wind speed. By measuring the pressure applied to the piezoelectric sheet, the magnitude of the wind speed can be calculated. A greater pressure means a stronger wind force.

[0071] When the wind acts on the device, causing the connecting rod 9 to swing, the connecting rod 9 will press a specific piezoelectric sheet in the direction of the wind. After being pressed, according to the piezoelectric effect, the movement of internal charges in the piezoelectric sheet will generate a voltage, and the generated voltage signal will be captured and converted into a digital signal for subsequent data processing; the piezoelectric sheets are evenly distributed along the circumferential direction of the connecting rod 9, and each piezoelectric sheet can independently detect the pressure change in its location. By analyzing which piezoelectric sheet receives the greatest pressure, it can be determined from which direction the wind mainly blows. At the same time, by comparing the pressure differences received by each piezoelectric sheet, the wind direction can be further refined, and even the change in the wind direction can be detected; the estimation of the wind speed is based on the relationship between the voltage value generated by the piezoelectric sheet and the wind pressure. During the system calibration phase, a quantitative relationship between pressure and voltage will be established for real-time calculation of the wind speed, and the digital signal processor will convert the received voltage into a wind speed value, which requires a pressure-wind speed conversion model established previously through experiments or theories.

[0072] In any of the above embodiments, the first detection part further includes a first detection ball 1 connected to the connecting rod 9, and the first sensor is installed inside the first detection ball 1; the first sensor is a sound sensor 101, and the sound sensor 101 is used to obtain the noise data when the ocean wind flows through the first detection ball 1.

[0073] The noise data is used to generate the first wind speed data and correct the second wind speed data. The magnitude of the current wind force can be directly obtained from the magnitude of the sound in the noise data and used as the first wind speed data. Since the swing amplitude of the connecting rod 9 under the drive of different forces does not show an accumulative relationship or the swing amplitude after long-term use is different from that at the initial use under the same wind force, this increases the accumulative error of the measurement. The second wind speed data detected by the swing of the connecting rod 9 can be directly corrected through the noise data.

[0074] In this embodiment, the sound sensor 101 is used to obtain the noise data generated when the ocean wind flows around the first detection ball 1. These noise data may include the sound of the wind blowing on the surface of the detection ball or the sound generated by the wind on other objects in this area; by analyzing the characteristics (such as frequency, intensity, and duration) of the captured sound, the speed and direction of the wind can be indirectly inferred.

[0075] The sound sensor 101 typically includes one or more microphone elements that can convert sound waves into electrical signals. When sound waves hit the sound sensor 101, they cause physical vibrations in the internal components of the sound sensor 101, such as membranes or sheets. This vibration is then converted into electrical signals that represent the characteristics of the sound waves, such as amplitude (loudness), frequency (pitch), and waveform (the texture or color of the sound). When the wind flows through the first detection sphere 1, it generates specific sound patterns on the surface of the sphere and in the surrounding space. These sound patterns vary depending on the speed of the wind, the direction of the wind, and the stability of the wind. By precisely analyzing these noise data (using methods such as spectral analysis and sound recognition technology), the system can identify specific wind force characteristics.

[0076] By analyzing the intensity of the sound generated when the wind passes through the first detection sphere 1, the wind speed is directly estimated. The magnitude (amplitude) of the sound is proportional to the wind speed, so it can be used as a direct measurement basis for the first wind speed data. Since the swing amplitude of the connecting rod 9 may change due to long-term use or different wind forces, directly using the swing of the connecting rod 9 to measure the wind speed may introduce errors. The noise data provides an independent measurement means for verifying and calibrating the second wind speed data and reducing cumulative errors.

[0077] The sound sensor 101 is inside the first detection sphere 1 to capture the sound generated when the wind flows through. The greater the wind speed, the stronger the force hitting the first detection sphere 1, and the greater the corresponding sound amplitude. The intensity (amplitude) of the sound is converted into electrical signals by the sound sensor 101, and then these electrical signals are quantified into numerical values of sound intensity to estimate the wind speed. The captured sound signals are amplified, filtered, and digitized and then converted into data that can be directly analyzed. Specific algorithms calculate the first wind speed data based on the magnitude of the sound. These algorithms are based on pre-set relationships (the relationship curve between sound intensity and wind speed), which are established during system calibration. The second wind speed data, determined by the swing amplitude of the connecting rod 9, may accumulate errors due to mechanical wear, external interference, or non-linear response. By comparing the first wind speed data (sound measurement) with the second wind speed data (measurement of the swing of the connecting rod 9), any inconsistencies can be identified and adjusted. If there are significant differences between the first wind speed data and the second wind speed data, the system can automatically adjust the calibration parameters to ensure the accuracy of the second wind speed data. This dual measurement method (sound and physical swing) allows the system to continuously self-optimize by adjusting the measurement strategy and calibration standards through real-time feedback. During long-term operation, the system can automatically adapt to the effects of environmental changes and equipment aging by continuously comparing and analyzing data, maintaining the high accuracy and reliability of the measurement data.

[0078] Specifically, the steps for the system to adjust the calibration parameters include:

[0079] Data comparison:

[0080] Periodically or continuously compare the first wind speed data (usually collected by a sensor directly measuring the wind speed, such as a sound sensor) with the second wind speed data (data measured through the swing of the connecting rod and the piezoelectric sheet).

[0081] Analyze the difference between the two to determine whether there is a significant deviation.

[0082] Deviation threshold setting:

[0083] Set an acceptable deviation threshold, such as 5%. When the deviation between the two sets of data exceeds this threshold, trigger the calibration procedure;

[0084] The threshold can be adjusted according to specific applications and accuracy requirements.

[0085] Automatic calibration execution:

[0086] If the deviation between the second wind speed data and the first wind speed data exceeds the threshold, the system automatically adjusts the calibration parameters. This may include modifying the sensitivity settings of the sensor, correcting the algorithm, or dynamically adjusting the position of the piezoelectric sheet relative to the connecting rod;

[0087] The adjustment of the calibration parameters is based on a preset calibration curve or the optimal solution obtained through a machine learning algorithm.

[0088] Feedback mechanism:

[0089] After adjustment, the system collects data again and compares the new first wind speed and second wind speed data to verify the calibration effect;

[0090] If there is still a deviation in the data, the system can further fine-tune the calibration parameters or perform a more in-depth diagnosis.

[0091] Recording and learning:

[0092] The system records the parameters and results of each calibration for optimizing future calibration processes;

[0093] Utilize historical data and results, and adopt machine learning techniques to optimize the calibration process, making the system more intelligent and adaptive.

[0094] Furthermore, a through hole for the connecting rod 9 to pass through is provided at the top of the second detection ball 4. A bellows 2 is connected between the first detection ball 1 and the second detection ball 4, and the bellows 2 covers the through hole and is sleeved on the portion of the connecting rod 9 outside the second detection ball 4. The bellows 2 is made of a flexible material.

[0095] As described above, the corrugated pipe 2 covers the connecting rod 9, protecting the connecting rod 9 from direct exposure in the marine environment, such as brine corrosion, marine organism attachment, or mechanical damage; the flexible material of the corrugated pipe 2 allows the connecting rod 9 to move freely under the action of wind force without being restricted, while maintaining good sealing performance to prevent moisture and impurities from entering the interior of the detection sphere; the corrugated pipe 2 can absorb part of the impact and vibration caused by wind force or waves, reducing the influence of these external forces directly acting on the connecting rod 9 and the detection sphere.

[0096] When the connecting rod 9 passes through the top through-hole of the second detection sphere 4, the corrugated pipe 2 covers the through-hole and extends to the external part of the connecting rod 9. This configuration forms a continuous protective layer, preventing seawater and impurities from directly contacting the connecting rod 9 and the through-hole. The flexible structure of the corrugated pipe 2 allows the connecting rod 9 to perform necessary movements under the action of wind force, such as bending or slight displacement, without being overly physically restricted; the design of the corrugated structure provides a high degree of flexibility, enabling the pipe material to withstand the movement of the connecting rod 9 without breaking. This design also maintains good sealing performance, preventing water and other external elements from seeping into the interior of the second detection sphere 4, which is crucial for maintaining the function of the internal second sensor. In addition, the corrugated pipe 2 can buffer the vibration caused by the swinging of the connecting rod 9, reducing the potential interference of these vibrations on the accuracy of the detection equipment; the material of the corrugated pipe 2 is usually corrosion-resistant and high-strength plastic or rubber, and these materials can resist the harsh conditions in the marine environment, including UV radiation, salt spray, and extreme temperature changes. By simplifying the maintenance requirements and extending the service life of the system, the corrugated pipe 2 improves the reliability and economic efficiency of the overall equipment.

[0097] In any of the above embodiments, all the piezoelectric wafers are connected to the inner wall of the inner groove through a support portion to ensure that each swing of the connecting rod 9 can be measured by the piezoelectric wafers at the same height, and the connecting rod 9 is connected to the inner wall of the inner groove through an elastic portion, and the bendable and deformable part is realized through the elastic portion at the bottom, which can avoid the deflection of the connecting rod 9 during swinging and ensure that the rod body is straight when applying force to the piezoelectric wafers.

[0098] The support portion includes a connecting ring 10 fixedly assembled with the piezoelectric wafer, and the connecting ring 10 is located between the piezoelectric wafer and the elastic portion, avoiding the interference of the deformation of the elastic portion on the pressure measurement of the piezoelectric wafer.

[0099] In this embodiment, all the piezoelectric wafers are connected to the inner wall of the inner groove through the support portion, ensuring that no matter how the connecting rod 9 swings, the piezoelectric wafers are always at the same height, thus ensuring the consistency of each measurement; the connecting rod 9 is connected to the inner wall of the inner groove through the elastic portion, and this elastic part allows the connecting rod 9 to deform flexibly when subjected to the action of wind force, while preventing the connecting rod 9 from skewing or twisting during swinging, ensuring that the connecting rod 9 can remain upright when applying force to the piezoelectric wafers.

[0100] The supporting part fixes all the piezoelectric wafers at specific positions within the inner groove. This fixing method ensures that no matter how the connecting rod 9 moves or swings, all the piezoelectric wafers can receive the pressure applied by the connecting rod 9 at the same height. This consistent positioning is the key to measurement accuracy because it eliminates measurement deviations caused by different positions of the piezoelectric wafers. The elastic part is usually made of silicone, rubber or other flexible materials, which can provide sufficient elasticity without damaging the connectivity. When the connecting rod 9 is subjected to an external force, this elastic part can deform appropriately, absorb part of the force, and reduce the pressure directly acting on the piezoelectric wafers. The design of the elastic part not only protects the piezoelectric wafers from excessive pressure damage, but also ensures the positive alignment of the connecting rod 9 when applying force, avoiding measurement errors caused by the skew of the connecting rod 9. Through this structural design, even under strong wind forces, the system can maintain a high degree of stability and responsiveness. The piezoelectric wafers can accurately measure the pressure changes generated by the wind force, and these measurement data reflect the actual characteristics of the wind. In addition, the application of the elastic part also helps to extend the service life of the device because it reduces mechanical wear and stress concentration.

[0101] The connecting ring 10 acts as a structural isolation component, blocking the direct mechanical interference caused by the deformation of the elastic part to the piezoelectric wafers. This ensures that the piezoelectric wafers only measure the pressure changes related to the wind force applied by the connecting rod 9. The connecting ring 10 fixes and supports the piezoelectric wafers, allowing the piezoelectric wafers to accurately respond to the pressure from the connecting rod 9 while keeping them stable.

[0102] The connecting ring 10 firmly fixes the piezoelectric wafers in their designed positions, preventing them from shifting or misaligning due to the actions of other parts of the system (such as the deformation of the elastic part). This fixing method ensures that the position and orientation of the piezoelectric wafers always remain consistent, which is crucial for maintaining the repeatability and reliability of the measurement. When the connecting rod 9 swings under the action of the wind force, the elastic part may produce a certain amount of deformation. Without the isolation of the connecting ring 10, this deformation may be directly transmitted to the piezoelectric wafers, resulting in incorrect pressure readings. The connecting ring 10 effectively blocks this interference, ensuring that the piezoelectric wafers only respond to the pressure changes directly caused by the wind force. The design and material selection of the connecting ring 10 usually aim to optimize the force transmission path. The connecting ring 10 transmits the pressure received from the connecting rod 9 to the piezoelectric wafers in the most direct and undisturbed way, which can minimize the errors caused by signal loss and deformation. The connecting ring 10 not only provides structural support, but also plays a key role in the responsiveness and sensitivity of the entire detection system. By keeping the piezoelectric wafers in the optimal position and state, the connecting ring 10 helps the system to quickly and accurately respond to the wind force changes in the environment.

[0103] In any of the above embodiments, the support portion further includes a plurality of support rods 11 for connecting the connection ring 10 and the inner groove; all the support rods 11 are telescopically arranged so that the piezoelectric sheet can correspond to the connecting rod 9 at different heights along the axial direction of the connecting rod 9, thereby realizing the change of the moment of the wind force on the piezoelectric sheet within different marine wind force ranges, and at least one support rod 11 is an electric telescopic rod, and the electric telescopic rod adjusts the position corresponding to the connecting rod 9 along the axial direction by extending the length, so as to perform automatic adaptation within different wind force ranges.

[0104] In this embodiment, the telescopic design of the support rod 11 allows the piezoelectric sheet to move to different heights along the axial direction of the connecting rod 9, so that the position of the piezoelectric sheet corresponding to the connecting rod 9 can be adjusted according to different wind force conditions; the electric telescopic rod can automatically adjust its extension length according to the wind speed data to change the position of the piezoelectric sheet, so as to adapt to different wind force ranges; by changing the height of the piezoelectric sheet, the moment applied by the wind force on the piezoelectric sheet can be adjusted, which helps to optimize the induction efficiency and measurement accuracy of the piezoelectric sheet.

[0105] The data processing unit is located inside the controller 6. The controller 6 receives data from the wind speed sensor and calculates the ideal position of the piezoelectric sheet according to these data. According to the magnitude of the wind force, the controller 6 will instruct the electric telescopic rod to adjust its length, thereby raising or lowering the position of the piezoelectric sheet. The adjustment process of the electric telescopic rod is automatic, ensuring that the piezoelectric sheet is always in the best position to respond to the current wind force conditions; all the support rods 11, including the electric telescopic rod, work together to ensure that the piezoelectric sheet can be accurately positioned along the axial direction of the connecting rod 9. These support rods 11 not only support the piezoelectric sheet but also ensure its stability under the action of the wind force. The telescopic support rod 11 design allows the system to dynamically adjust the height of the piezoelectric sheet to adapt to the moment change caused by different wind speeds; the piezoelectric sheet will experience different moments at different heights of the connecting rod 9, which affects its ability to generate electrical signals. By precisely controlling the position of the piezoelectric sheet, the system can optimize the moment to ensure that each wind force action can be effectively converted into a measurable electrical signal. This fine adjustment function enables the system to measure the wind speed and direction more accurately and reduce errors caused by improper position; by automatically adjusting the height of the piezoelectric sheet, the system can quickly adapt to changes in the environment and provide real-time and accurate wind force data. This design increases the reliability and effectiveness of the system in complex marine environments and reduces the need for manual adjustment and maintenance costs.

[0106] In any of the above embodiments, the marine wind speed and direction sensor mechanism further includes a controller 6, and the controller 6 is installed on the inner wall of the inner groove.

[0107] The controller 6 is respectively connected to the first sensor and the electric telescopic rod, so as to adjust the extension length of the electric telescopic rod according to the first wind speed data. By correcting the extension length of the electric telescopic rod with the first wind speed data detected without swing, the axial height of the piezoelectric sheet corresponding to the connecting rod 9 can be adjusted, so as to achieve the effect of automatic adjustment without manual participation.

[0108] In this embodiment, the controller 6 receives the wind speed data from the first sensor (the sound sensor 101). These data provide direct information about the current wind force and provide basic data for the control system; the controller 6 automatically adjusts the extension length of the electric telescopic rod according to the received wind speed data to change the axial height of the piezoelectric sheet relative to the connecting rod 9, so as to adapt to different wind forces; by precisely adjusting the position of the piezoelectric sheet, the controller 6 ensures that the measuring device can measure the wind speed at the optimal height, improving the accuracy of the data and the response speed of the system.

[0109] The microprocessing unit built in the controller 6 analyzes the wind speed data received from the first sensor. According to these data, the controller 6 calculates the ideal height at which the piezoelectric sheet should be located to measure the wind force most accurately. The controller 6 uses a preset algorithm or model to dynamically adjust the length of the electric telescopic rod according to the change of the wind speed to change the axial position of the piezoelectric sheet; the electric telescopic rod receives the instruction from the controller 6 and adjusts its length according to these instructions. This adjustment of the length directly affects the position of the piezoelectric sheet, moving it to the optimal measurement position required to adapt to the current wind speed. This automatic adjustment mechanism eliminates the need for manual repositioning, enabling the system to respond quickly and precisely to environmental changes; the control system is designed to monitor and respond to changes in environmental conditions in real time, ensuring the highest measurement efficiency and accuracy under any given wind force conditions. By adjusting the height of the piezoelectric sheet, the system can maximize the influence of the wind force on the piezoelectric sheet and reduce the measurement error caused by improper position; the automatic adjustment function of the controller 6 reduces the dependence of the system on external intervention and enhances the usability and reliability of the device in harsh or unpredictable marine environments. The automation ability of the system not only improves the operation efficiency but also reduces the complexity and cost of long-term maintenance and operation.

[0110] Further, the controller 6 includes a storage battery 601 arranged axially along the connecting rod 9. The storage battery 601 is installed on the inner wall of the inner groove and is used to supply power to the controller 6, the first sensor, the second sensor, and the electric push rod.

[0111] As described above, the storage battery 601 provides the necessary power for the controller 6 and the sensors and electric telescopic rods connected thereto, ensuring that the system can operate normally even without an external power source; by integrating the storage battery 601, the system can operate independently in remote marine environments without being restricted by power supply, improving the application scope and flexibility of the system; during continuous monitoring and data recording, an uninterrupted power supply is essential, and the storage battery 601 guarantees the continuity of data acquisition and processing, avoiding data loss.

[0112] The storage battery 601 stores energy through an electrochemical reaction. When system components such as sensors or electric telescopic rods require power, the storage battery 601 supplies the required power through a circuit. The controller 6 usually includes a battery management system (BMS) that is responsible for monitoring the battery's charge status, voltage, temperature, etc., ensuring that the battery operates under safe and optimal working conditions; the controller 6 distributes the power of the storage battery 601 according to the power requirements of each component. For example, when the electric telescopic rod needs to adjust its position to adapt to wind changes, the controller 6 instructs the storage battery 601 to provide power. The controller 6 is also responsible for reducing power consumption when the system is idle, such as adjusting the sensors to a low-power mode to extend the battery's service life; when an external power source is available (such as charging through a solar panel), the controller 6 manages the charging process of the storage battery 601 to ensure high charging efficiency and maintain a good health status of the battery. The controller 6 also monitors the battery performance. If it detects a decrease in battery capacity or other performance issues, it can make necessary adjustments or issue maintenance warnings.

[0113] Furthermore, the controller 6 also includes a charging panel 602 installed on the top of the first detection sphere 1, and the charging panel 602 is a solar charging panel.

[0114] As described above, the charging panel 602 captures sunlight and converts it into electrical energy to charge the storage battery 601, ensuring that the system can continue to operate even in remote marine environments where it is inconvenient to access conventional power sources; using solar energy as the energy source reduces the dependence on fossil fuels and improves the environmental friendliness and sustainability of the system; since the charging panel 602 provides a reliable energy supply method, the maintenance requirements of the system are reduced because there is no need to frequently replace the battery or perform other energy supply operations.

[0115] The charging panel 602 is composed of multiple photovoltaic cells, usually made of silicon-based materials such as monocrystalline silicon or polycrystalline silicon. These photovoltaic cells can convert the energy of sunlight into electrical energy, and this process is called the photovoltaic effect. When sunlight shines on the charging panel 602, the electrons in the photovoltaic cells are excited and flow, thus generating an electric current. These electric currents are collected and transmitted through a circuit to the storage battery 601 for storage; The controller 6 includes a battery management system (BMS), which is responsible for monitoring the electrical energy received from the charging panel 602 and storing it safely and efficiently in the storage battery 601. The BMS regulates the charging process to prevent overcharging and over-discharging, protects the health of the battery and extends its service life. At the same time, it ensures that electrical energy can be extracted from the storage battery 601 when needed to supply other components of the system; The controller 6 can automatically adjust the charging strategy according to environmental conditions (such as light intensity) and system requirements to optimize the energy utilization rate. When the light is sufficient, the controller 6 preferentially uses solar energy for charging and meets the immediate power demand of the system. When the light is insufficient, it manages the power provided by the storage battery 601 to ensure the continuous operation of the system.

[0116] In any of the above embodiments, the elastic part is the junction box 902. The junction box 902 is hollow, and side holes are provided for wires to pass through. The connecting rod 9 is axially provided with a connection hole 901, and the connection hole 901 communicates with the inner cavity of the junction box 902 and the inner cavity of the first detection ball 1 to obtain the first wind speed data of the first sensor and supply power to the first sensor for wiring.

[0117] In this embodiment, the junction box 902 arranges electrical connections and wiring inside through its hollow design, protecting these sensitive components from the influence of the external environment (such as seawater, moisture, corrosion, etc.); The wires in the junction box 902 enter and exit through the side holes. These holes not only provide a clear path for the wires but also reduce the risk of mechanical damage to the wires; The junction box 902 simplifies and protects the wire connection from the first sensor to the controller 6, ensuring the stability of power supply and data transmission.

[0118] Inside the junction box 902, it is connected to the inner cavities of the connecting rod 9 and the first detection sphere 1 through the connection holes 901. This setting allows wires to be safely led out from sensors (such as the sound sensor 101) in the first detection sphere 1, transmitted through the connecting rod 9 to other parts of the system, such as the storage battery 601 and the controller 6. The space inside the junction box 902 provides sufficient physical protection for the wires, preventing damage caused by external physical forces (such as swinging or vibration); the wires are introduced into or led out of the junction box 902 through the side through-holes. These through-holes are designed to be large enough to accommodate multiple wires and tight enough to prevent water and moisture from entering. These holes are also designed with waterproof seals, enhancing the durability and reliability of the overall system in the marine environment; the junction box 902 not only provides physical protection but also ensures clear and interference-free transmission of electrical signals and power. The orderly organization of the wires reduces the possibility of electromagnetic interference and signal loss. In addition, the design of the junction box 902 generally takes into account electrical safety, including short-circuit protection and easily maintainable interfaces.

[0119] Furthermore, the junction box 902 is made of rubber so that when the first detection sphere 1 and the connecting rod 9 are driven by the marine wind, one end of the connecting rod 9 can move circumferentially around the other end and the swinging of the connecting rod 9 can be achieved.

[0120] As can be seen from the above, the rubber material makes the junction box 902 have good elasticity and flexibility, allowing the connecting rod 9 to swing naturally under the action of the wind while maintaining the integrity and safety of the wire connection; rubber has excellent waterproof performance and can effectively block seawater and moisture, preventing them from corroding the wires and electrical components, which is especially suitable for the marine environment; the rubber junction box 902 can absorb and buffer the impact generated by the swinging of the connecting rod 9, protecting the internal wires from excessive stretching or compression.

[0121] The elasticity of the rubber material allows the junction box 902 to physically withstand the swinging and torsion of the connecting rod 9 without cracking or permanent deformation. This elasticity also allows the junction box 902 to conform to the movement when the connecting rod 9 swings, reducing the mechanical stress on the wires. When the first detection sphere 1 moves under the action of the wind, the junction box 902 allows the connecting rod 9 to rotate or bend finitely around its fixed point without affecting the structural integrity of the wires; the rubber material is naturally waterproof, and the design of the junction box 902 includes sealing of the interfaces and through-holes to prevent moisture from entering. This is particularly crucial for marine applications because seawater can quickly corrode and damage electrical systems. The sealed design of the junction box 902 also prevents the intrusion of salts and other corrosive substances, extending the service life of the equipment; the rubber material of the junction box 902 can absorb part of the vibration and impact force generated by the swinging of the connecting rod 9, helping to protect the internal wires and electrical components from damage.
