Description

Technical Field

[0001] This invention relates to the field of marine equipment, and more specifically to marine environmental monitoring buoys that are easy to recover. Background Technology

[0002] Marine environmental monitoring is the core foundation for safeguarding marine ecological security, preventing marine disasters, and rationally developing marine resources. As an unmanned marine monitoring device, monitoring buoys have become a core component of the marine environmental monitoring system due to their ability to collect marine environmental parameters continuously and in real-time. With the continuous advancement of marine monitoring, the monitoring scope is expanding, and the requirements for monitoring accuracy are constantly increasing, placing higher demands on the practicality, stability, convenience, and economy of buoys.

[0003] According to the marine environmental monitoring buoy with reference number CN118478986A, this patent is a known prior art. This patent uses a drive unit to drive the annular wiping unit to operate. With the seawater splashing on the surface of the annular solar panel, the annular wiping unit can wet and wipe the bird droppings on the surface of the annular solar panel, which has the advantage of improving cleaning efficiency. However, it also has the following drawbacks: Since the buoy in this patent floats directly on the sea surface, it can only rise and fall with the waves when encountering waves. It cannot adapt to the dynamic changes of ocean waves and currents, and the buoy is prone to deflection and overturning, which affects the monitoring accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide a marine environmental monitoring buoy that is easy to recover, in order to solve the problem that when buoys are used to float directly on the sea surface, they can only rise and fall with the waves when they encounter waves, and cannot adapt to the dynamic changes of ocean winds, waves and currents, which can easily lead to buoy deviation and overturning, affecting the monitoring accuracy.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a marine environmental monitoring buoy that is easy to recover, comprising a buoy body and a buoyancy component, wherein the buoy body is disposed inside the buoyancy component and rotates back and forth slightly. The buoyancy assembly includes a buoyancy ring and a support ring, with the buoy body rotatably connected to the inside of the buoyancy ring and the support ring disposed on the outside of the buoyancy ring; An anchoring assembly is installed on the outside of the support ring.

An isolation assembly is arranged between the auxiliary anchor and the central anchor. The buoy body has a protruding end at its bottom, and multiple actuating plates are fixedly connected around the outside of the protruding end. Multiple hollow conical ends are fixedly connected to the bottom surface of the buoy body.

[0006] As a further improvement to the above scheme, the buoy body is configured as a disc shape, and a polygonal protrusion is fixedly connected to the top of the buoy body. Photovoltaic panels are provided on multiple outer edges of the polygonal protrusion, and a transparent spherical cover is provided on the outer side of the polygonal protrusion. The transparent spherical cover is fixedly connected to the top of the buoy body.

[0007] As a further improvement to the above solution, two U-shaped frames are fixedly connected to the top of the buoyancy ring. The two U-shaped frames are arranged in a cross shape. A drive assembly is fixedly connected to the bottom of the connection between the two U-shaped frames. The drive assembly includes a waterproof shell. A servo motor is installed inside the waterproof shell. A waterproof cylinder is fixedly connected to the drive shaft at the bottom of the servo motor. The bottom of the waterproof cylinder is fixedly connected to the top of the polygonal boss. A fixing plate is installed on the outside of the waterproof cylinder. The fixing plate is located above the transparent spherical cover.

[0008] As a further improvement to the above solution, a connecting rod is fixedly connected to the inner side of the U-shaped frame, an arc-shaped cleaning plate is fixedly connected to one end of the connecting rod, a cleaning brush is fixedly connected to the inner side of the arc-shaped cleaning plate, and the cleaning brush is attached to the surface of the transparent spherical cover.

[0009] As a further improvement to the above solution, the clamp and the hollow shell are respectively provided with an opening and an interface on one side, and a connecting plate is fixedly connected to both sides of the opening and the interface. A fixing bolt is provided between the two corresponding connecting plates, and the opening and the interface are for the support ring to be inserted.

[0010] As a further improvement to the above solution, a cavity is provided inside the hollow shell, and an injection port is provided at the top of the hollow shell. The injection port is connected to the cavity, and a sealing cap is threaded onto the outside of the injection port.

[0011] As a further improvement to the above solution, a universal swivel joint is provided at the bottom of the hollow shell, and the tops of the auxiliary anchor and the center anchor are respectively connected to the auxiliary rope and the center rope, and the tops of the auxiliary rope and the center rope are rotatably set in the corresponding universal swivel joint.

[0012] As a further improvement to the above solution, the isolation component includes a fixing sleeve, and multiple fixing sleeves are provided. The multiple fixing sleeves are respectively fixedly connected to the outside of the auxiliary rope and the center rope. A rotating ring is rotatably connected to the outside of the fixing sleeve on the center rope. An elastic rod is fixedly connected between the outside of the fixing sleeve on the outside of the auxiliary rope and the rotating ring.

[0013] As a further improvement to the above solution, a groove is provided at the top of the support ring, a corrosion-resistant spring is fixedly connected in the groove, a pop-out ball is fixedly connected at the top of the corrosion-resistant spring, and the upper half of the pop-out ball extends out of the groove. Multiple pop-out balls are provided, and two adjacent pop-out balls block the two ends of the anchoring component.

[0014] As a further improvement to the above solution, a top frame is fixedly connected to the top of the U-shaped frame, a detection component is fixedly connected to the top of the top frame, a power supply box is fixedly connected inside the top frame, and a fixing rod is fixedly connected between the support ring and the buoyancy ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The buoy body rotates back and forth slightly by the drive component. This slight rotation not only stabilizes the buoy's attitude and suppresses its overall swaying, ensuring the monitoring accuracy of the detection component and avoiding data deviation caused by buoy swaying, but also prevents the cable from tangling in one direction. With the help of the universal joint and isolation component, the slight rotation does not require the high-load drive of the servo motor, which can significantly reduce the power consumption of the servo motor. Combined with the efficient power supply of the photovoltaic panel, it enhances the endurance.

[0016] 2. When the drive component rotates the buoy body, the actuating plate not only rotates with the buoy body, disturbing the water flow and buffering the impact of the water flow on the buoy, further improving the buoy's attitude stability; it can also break up floating ice on the sea surface and push away small floating objects to prevent them from hitting the buoy body. The cleaning plate and cleaning brush on the inside of the U-shaped frame cooperate with the rotation of the buoy body to achieve autonomous cleaning of the transparent sphere, eliminating the need for manual boarding for cleaning, reducing maintenance costs. The servo motor of the drive component cooperates with the small-amplitude rotation of the buoy body, not only providing power to the cleaning mechanism, but also adjusting the orientation of the photovoltaic panel so that the photovoltaic panel always faces the direction of sunlight, improving solar energy utilization and reducing battery energy consumption.

[0017] 3. The hollow outer shell not only serves as the mounting carrier for the auxiliary anchor, providing fixation and protection to prevent seawater erosion and impact, thus extending the auxiliary anchor's service life, but also allows for the injection / discharge of counterweight materials through the inlet, enabling flexible adjustment of the anchoring weight to adapt to different sea conditions such as nearshore, shallow sea, and mid-to-far sea. Furthermore, the hollow configuration can be selected to increase buoyancy and further optimize buoy stability. The support ring prevents external impurities from approaching the buoy body. The detachable connection between the hollow outer shell and the clamp allows for quick disassembly of the anchoring components during recovery, further simplifying the recovery process and facilitating the maintenance and replacement of the anchoring components.

[0018] 4. The pop-out ball not only limits the anchoring components, preventing them from sliding or colliding on the support ring and ensuring their secure installation, but also prevents anchoring deviation due to component slippage, thus affecting monitoring accuracy. Furthermore, when the buoy body drives the central rope to rotate, the rotating ring rotates synchronously with the central rope, and the elastic rod does not transmit rotational force, preventing the auxiliary rope from rotating along with it and reducing the problem of cable twisting. At the same time, the elastic structure of the elastic rod can buffer the impact of wind, waves, and ocean currents on the anchoring rope, reducing the tensile deformation and wear of the anchoring rope.

[0028] The above description of the main component symbols, together with the accompanying drawings and specific embodiments, provides a more detailed explanation of the present invention. Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. It should be understood that the following description is merely illustrative and not intended to limit the invention.

[0030] The specific embodiments of the present invention will be described in detail below.

[0031] Please see Figure 1 This embodiment provides a marine environmental monitoring buoy that is easy to recover, including a buoy body 2 and a buoyancy component. The buoy body 2 is installed inside the buoyancy component and rotates back and forth slightly. The buoy body 2 is made of high-strength engineering plastic, and its surface is coated with a double-layer anti-corrosion coating and an anti-marine organism adhesion coating after sandblasting. The anti-corrosion coating is a fluorocarbon coating, and the anti-marine organism adhesion coating is a nano antifouling coating. The buoy body 2 can be controlled to rotate back and forth slightly within ±30°.

[0032] Two U-shaped frames 6 are fixedly connected to the top of the buoyancy ring 1. The two U-shaped frames 6 are arranged in a cross shape. A drive assembly 9 is fixedly connected to the bottom of the connection between the two U-shaped frames 6. The drive assembly 9 includes a waterproof shell and a servo motor is installed inside the waterproof shell.

[0033] The buoy body 2 is designed as a disc, and a polygonal protrusion 24 is fixedly connected to the top of the buoy body 2. Photovoltaic panels are provided on the outer edge of the polygonal protrusion 24, and a transparent spherical cover 10 is fixedly connected to the outer side of the polygonal protrusion 24. The polygonal structure can maximize the use of solar energy receiving area, ensure that the photovoltaic panels can receive sunlight from different angles, improve the solar energy utilization rate, and provide a stable power supply for the detection component 8, drive component 9 and other equipment on the buoy.

[0034] Please refer to the following: Figure 1 and Figure 3 A top frame 7 is fixedly connected to the top of the U-shaped frame 6, and a detection component 8 is fixedly connected to the top of the top frame 7. A power supply box 16 is fixedly connected inside the top frame 7. The power supply box 16 integrates a battery, a photovoltaic charging controller, and a converter. All three are fixedly installed on an insulating mounting plate inside the power supply box 16. The wiring connections all use waterproof terminals. The stable DC power output from the photovoltaic panel is rectified and regulated by the photovoltaic charging controller, and then converted into a stable current, which is connected to the charging port of the battery to achieve safe charging of the battery. At the same time, the photovoltaic charging controller has overcharge, over-discharge, and overload protection functions to prevent damage to the battery. The current output from the battery in the power supply box 16 is converted by the converter to power the servo motor and the detection component 8. Since the buoy body 2 rotates slightly back and forth, setting the connecting wire to be longer can prevent the wire from getting tangled when the buoy body 2 rotates, thus avoiding affecting the rotation.

[0035] The detection component 8 includes a temperature sensor (model: DS18B20), a salinity sensor (model: SEN0193), a pH sensor (model: SEN0161), and a turbidity sensor (model: SEN0259). The detection end of the detection component 8 can be wound down along the U-shaped frame 6 and extended into the sea surface (the installation does not affect the anchor rope and will not get tangled. The detection component 8 can also detect only the environment on the sea surface, and is equipped with temperature, humidity and wind sensors). It can realize the real-time acquisition and transmission of multiple parameters of the marine environment. At the same time, a light sensor can be added to detect the light intensity.

[0036] Please refer to the following: Figure 1The buoyancy assembly includes a buoyancy ring 1 and a support ring 4. A fixing rod 3 is fixedly connected between the support ring 4 and the buoyancy ring 1. The buoy body 2 is rotatably connected to the inside of the buoyancy ring 1. The support ring 4 is located on the outside of the buoyancy ring 1. The buoyancy ring 1 is made of engineering plastic (or uses) and its surface is coated with an anti-marine organism adhesion coating and a waterproof sealing coating. The buoy body 2 is rotatably connected to the inside of the buoyancy ring 1 through a stainless steel rotating shaft. Waterproof sealing bearings are provided at the connection points between the rotating shaft and the buoy body 2 and the buoyancy ring 1 to ensure smooth rotation and prevent seawater from entering the connection points, allowing the buoy body 2 to rotate back and forth slightly. The support ring 4 can be made of hollow stainless steel to provide support and protection, preventing the buoyancy ring 1 from being directly damaged by external impacts (such as ice floes or floating objects).

[0037] Anchoring components 5 are installed on the outside of the support ring 4. Multiple anchoring components 5 are evenly arranged in a ring array to ensure uniform anchoring force, improve the anchoring stability of the buoy, and prevent the buoy from shifting or overturning under the action of wind, waves, and ocean currents.

[0038] Please continue reading. Figure 1 , Figure 3 , Figure 4 and Figure 7 The anchoring component 5 includes a hollow shell 30 and a clamp 27. The hollow shell 30 and the clamp 27 are sleeved on the outside of the support ring 4. An auxiliary anchor 19 is rotatably provided at the bottom end of the hollow shell 30. A central anchor 21 is rotatably provided at the center of the bottom end of the buoy body 2. An isolation component is provided between the auxiliary anchor 19 and the central anchor 21. A protruding end is provided at the bottom of the buoy body 2. Multiple actuating plates 23 are fixedly connected around the outside of the protruding end. Multiple hollow conical ends 22 are fixedly connected to the bottom end of the buoy body 2. The agitator 23 can disturb the water flow when the buoy body 2 rotates, which on the one hand helps stabilize the buoy's attitude, and on the other hand can break up floating ice on the sea surface and push away small floating objects to prevent them from hitting the buoy or getting tangled in the anchoring line. The hollow conical end 22 is made of engineering plastic. The hollow structure can reduce the overall weight of the buoy and optimize the buoy force distribution. At the same time, the setting of the tip can make the bottom of the buoy body 2 have an irregular shape distribution, reduce the flat surface, and prevent marine plankton or barnacles from attaching to the bottom of the buoy body 2.

[0039] Please refer to the following: Figure 1-3 and Figure 5A waterproof cylinder 15 is fixedly connected to the drive shaft at the bottom of the servo motor. The bottom end of the waterproof cylinder 15 is fixedly connected to the top end of the polygonal boss 24. A fixing plate 11 is provided on the outside of the waterproof cylinder 15. The fixing plate 11 is located above the transparent spherical cover 10. A connecting rod 12 is fixedly connected to the inside of the U-shaped frame 6. An arc-shaped cleaning plate 13 is fixedly connected to one end of the connecting rod 12. A cleaning brush 14 is fixedly connected to the inside of the arc-shaped cleaning plate 13. The cleaning brush 14 is attached to the surface of the transparent spherical cover 10. The connection between the waterproof cylinder 15 and the transparent spherical cover 10 is sealed and waterproofed. A gap is left between the bottom end of the fixing plate 11 and the top end of the arc-shaped cleaning plate 13 to facilitate the fixing plate 11 to block the top end of the arc-shaped cleaning plate 13 and at the same time play a limiting role to prevent the top end of the arc-shaped cleaning plate 13 from deforming.

[0040] The servo motor is a DC servo motor, model 110BYG350, with a power of 50-100W. Driven by the servo motor, the transparent dome 10 and the buoy body 2 can rotate back and forth synchronously in small amplitudes. This provides power for the autonomous cleaning mechanism and can also adjust the orientation of the photovoltaic panel to improve the solar energy reception efficiency. At the same time, it can achieve low power consumption operation in conjunction with the attitude adjustment of the buoy body 2. When the buoy body 2 and the transparent dome 10 rotate, the cleaning brush 14 can clean the surface of the transparent dome 10 without cleaning dead corners, effectively removing marine organisms, dust and marine debris attached to the surface, and ensuring the transparency of the transparent dome 10.

[0041] Please see Figure 1 and Figure 7 The clamp 27 and the hollow shell 30 have openings 28 and interfaces 32 on one side, respectively. Connecting plates 29 are fixedly connected to both sides of the openings 28 and interfaces 32. Fixing bolts 33 are provided between the two connecting plates 29. By tightening the fixing bolts 33, the clamp 27 and the hollow shell 30 can be firmly fixed to the outside of the support ring 4, ensuring that the anchoring component 5 does not loosen under the action of wind, waves and ocean currents. At the same time, the detachable connection method facilitates the disassembly and assembly of the anchoring component 5. When the anchoring component 5 is damaged, it can be quickly disassembled and replaced, improving maintenance efficiency and facilitating the disassembly of the anchoring component 5 during buoy recovery, reducing the difficulty of recovery.

[0042] Please continue reading. Figure 7 The hollow outer shell 30 has a cavity inside, and an injection port 31 is provided at the top of the hollow outer shell 30. The inside of the injection port 31 is connected to the inside of the cavity, and a sealing cap is threaded on the outside of the injection port 31.

[0043] The inner wall of the cavity is coated with a waterproof sealing coating. Weights (such as seawater or sand) can be injected into the cavity through the injection port 31 to adjust the weight of the anchoring component 5, adapting to ocean currents and wave conditions in different sea areas and ensuring stable buoy anchoring. In nearshore waters with smaller waves, the hollow outer shell 30 can remain hollow, with only a sealing cap installed on the injection port 31, increasing the buoyancy of the entire device and further improving the stability of the buoy. When recovering the buoy, the weights in the cavity can be discharged through the injection port 31, reducing the overall weight of the buoy. No large salvage equipment is required; it can be easily salvaged with only a small boat.

[0044] Please refer to the following: Figure 1 and Figure 3 The bottom of the hollow shell 30 is provided with a universal rotary joint 17. The tops of the auxiliary anchor 19 and the center anchor 21 are respectively connected to the auxiliary rope 18 and the center rope 20. The tops of the auxiliary rope 18 and the center rope 20 are rotatably set in the corresponding universal rotary joint 17.

[0045] Specifically, auxiliary rope 18 and central rope 20 are fixedly connected to the top of auxiliary anchor 19 and central anchor 21, respectively. Auxiliary rope 18 and central rope 20 are made of high-strength corrosion-resistant nylon rope. Universal rotary joint 17 has a double connection port structure. The tops of auxiliary rope 18 and central rope 20 are specially treated and fixed with crimp terminals to form a ring joint. The inner diameter of the ring joint matches the diameter of the connecting pin of universal rotary joint 17.

[0046] The annular connector at the top of the auxiliary rope 18 is fitted onto the connecting pin of the universal rotary joint 17 at the bottom of the hollow shell 30. The two ends of the connecting pin are fixed by cotter pins. The cotter pins are made of stainless steel and are inserted into the reserved holes of the connecting pins and bent to prevent the annular connector from falling off the connecting pins. The annular connector at the top of the center rope 20 is fitted onto the connecting pin of the universal rotary joint 17 at the bottom center of the buoy body 2. It is fixed by the same cotter pin as the auxiliary rope 18 to ensure a firm connection. Since this is existing technology, it will not be described in detail.

[0047] Please see Figure 3 and Figure 6 The isolation component includes a fixing sleeve 26, and multiple fixing sleeves 26 are provided. The multiple fixing sleeves 26 are respectively fixedly connected to the outside of the auxiliary rope 18 and the center rope 20. A rotating ring 36 is rotatably connected to the outside of the fixing sleeve 26 on the center rope 20. An elastic rod 25 is fixedly connected between the outside of the fixing sleeve 26 on the outside of the auxiliary rope 18 and the rotating ring 36.

[0048] When the drive assembly 9 drives the buoy body 2 to rotate back and forth, the buoy body 2 will cause the center rope 20 and the center anchor 21 to rotate slightly. The rotating ring 36 and the elastic rod 25 can isolate the auxiliary rope 18 and the center rope 20 to prevent them from getting tangled. At the same time, the fixing sleeve 26 of the center rope 20 can rotate within the rotating ring 36 to prevent the rotation of the center rope 20 from affecting the auxiliary rope 18.

[0049] Please see Figure 1 and Figure 8 The support ring 4 has a groove at its top, and a corrosion-resistant spring 35 is fixedly connected in the groove. A pop-out ball 34 is fixedly connected to the top of the corrosion-resistant spring 35, and the upper half of the pop-out ball 34 extends out of the groove. Multiple pop-out balls 34 are provided, and two adjacent pop-out balls 34 block the two ends of the anchoring component 5, thus limiting the position of the anchoring component 5.

[0050] The marine environmental monitoring buoy in this embodiment is used as follows: Before the buoy is deployed, according to the wind, waves and ocean current conditions of the deployment area, an appropriate amount of counterweight material is injected through the injection port 31 of the hollow shell 30 to adjust the weight of the anchoring component 5 (or the hollow shell 30 is placed hollow and a sealing cap is installed on the injection port 31 to increase the buoyancy of the entire device). Then, the clamp 27 and the hollow shell 30 are clamped onto the support ring 4 through the opening 28 and the interface 32. The anchoring component 5 is fixed to the outside of the support ring 4 by the fixing bolt 33. The unobstructed pop-out ball 34 limits the two sides of the anchoring component 5 to prevent the anchoring component 5 from sliding and colliding on the support ring 4. Next, the auxiliary anchor 19 and the center anchor 21 are connected to the universal joint 17 via the auxiliary rope 18 and the center rope 20. The elastic rod 25 and the fixing sleeve 26 of the isolation component isolate the auxiliary rope 18 and the center rope 20 to prevent entanglement. The double anchoring structure provides a stable positioning foundation for the buoy.

[0051] After deployment, the buoyancy ring 1 provides sufficient buoyancy to support the buoy to float on the sea surface. The support ring 4 and the fixing rod 3 enhance the structural stability of the buoyancy component. The buoy body 2 uses slight rotation to stabilize the buoy's attitude, prevent the cable from getting tangled in one direction, and effectively suppress the overall shaking of the device, ensuring the monitoring accuracy of the detection component 8. Moreover, this small-amplitude rotation does not require high-load drive of the servo motor, which greatly reduces the power consumption of the servo motor and achieves low-power operation.

[0052] The photovoltaic panel on the polygonal protrusion 24 receives sunlight to generate electricity, which is stored in the battery of the power supply box 16 to continuously power the detection component 8, drive component 9 and other equipment, ensuring the normal operation of the equipment. The detection component 8 collects environmental parameters such as temperature, salinity and humidity of the marine environment in real time and transmits the data to the shore-based monitoring center to realize real-time monitoring of the marine environment.

[0053] During operation, the servo motor of the drive component 9 actively drives the transparent dome 10, the buoy body 2, and the actuating plate 23 to rotate synchronously in small amplitudes, causing the transparent dome 10 and the cleaning brush 14 on the inner side of the U-shaped frame 6 to rub against each other. The cleaning brush 14 adheres to the surface of the transparent dome 10 to remove marine organisms, dust, and marine debris attached to the surface, ensuring the transparency of the transparent dome 10 (the cleaning area can also be expanded by setting multiple cleaning brushes 14 and connecting rods 12), ensuring the light-gathering efficiency of the photovoltaic panel and the monitoring accuracy of the detection component 8.

[0054] In addition, the agitator 23 rotates synchronously with the buoy body 2, which can effectively disturb the water flow. On the one hand, it can buffer part of the water flow impact, reduce the impact force of the water flow on the buoy body 2, and further improve the attitude stability of the buoy. On the other hand, after agitating the water flow, it can break up floating ice on the sea surface and push away small floating objects (such as plastic waste and seaweed), preventing them from hitting or approaching the buoy body 2, buoyancy ring 1 and anchoring component 5. At the same time, it can prevent floating objects from getting tangled in the anchoring rope, playing a comprehensive protective role and reducing the probability of equipment damage.

[0055] The universal swivel joint 17 allows the auxiliary rope 18 and the center rope 20 to rotate freely 360 degrees. In conjunction with the isolation component, it further prevents the anchoring rope from getting tangled, ensures stable anchoring, and eliminates the problem of cable twisting.

[0056] When the buoy needs to be retrieved, personnel actively approach the buoy body 2 via a vessel and discharge the counterweight material inside the hollow outer shell 30 through the injection port 31 to reduce the overall weight of the buoy; unscrew the fixing bolts 33 to quickly disassemble the anchoring component 5 to avoid the anchoring component 5 affecting the salvage operation; the buoy can be easily towed by a small vessel to complete the retrieval. After retrieval, each component can be maintained and replaced, and after re-injecting the counterweight, it can be deployed again, realizing the reuse of the buoy and reducing monitoring costs. It should be noted that a positioning device (GPS) can be added inside the buoy body 2 for later personnel positioning (after this device is put into use in the sea area, personnel can also regularly clean and inspect the device).

[0057] In the above solution, it should be noted that: the servo motor, battery, photovoltaic panel and detection component 8 involved in this embodiment are all existing products, and the specific structure, electrical connection method (circuit layout) and working principle of the servo motor, battery, photovoltaic panel and detection component 8 are all existing publicly available technical means. It should also be noted that the marine environmental monitoring buoy in this embodiment is also equipped with an existing manual control button. The manual control button (or external control system) is connected to the servo motor, battery, photovoltaic panel and detection component 8 by wires. When in use, the power supply is connected, and the operating status of the servo motor, battery, photovoltaic panel and detection component 8 can be adjusted by using the manual control button. The electrical connection method and control method of the manual control button adopt mature and public technical means in the field, and will not be described in detail here.

[0058] The above embodiments are merely preferred embodiments of the present invention. Any simple modifications, alterations, and substitutions made to the above embodiments based on the technical essence of the present invention shall fall within the scope of the technical solution of the present invention.
