Abstract

This invention discloses an easily disassembled PET buoy device, relating to the field of marine PET buoy technology. It includes a buoy, and further comprises a structural assembly, an initial positioning unit assembly, and a self-adjusting snap-fit ​​stabilizing assembly. This invention achieves portability breakthroughs in both disassembly process and operational difficulty through the coordinated cooperation of components. Firstly, the initial positioning unit assembly can quickly release the buoy from its initial fixed state without repeated disassembly of connectors. Secondly, the self-adjusting snap-fit ​​stabilizing assembly has a "reverse self-loosening" characteristic; when disassembly is required, simply moving the snap-fit ​​ring in the lateral reverse direction allows the buoy to return from the square groove to the circular groove, releasing it from the locked state. Combined with the modular support structure of the structural assembly, workers can directly remove the buoy from the device. The entire disassembly process requires no tools, significantly improving efficiency compared to traditional rope binding and snap-fit ​​connection methods.

Description

Technical Field

[0001] This invention relates to the field of PET buoy technology for ships, specifically to a PET buoy device that is easy to disassemble. Background Technology

[0002] In modern industry and civilian sectors, PET buoys are widely used in various critical applications due to their excellent corrosion resistance, high strength, and lightweight properties. In the maritime sector, the navigational warning function of PET buoys is crucial. They are typically deployed in series along the edges of waterways, in shallow waters, near reefs, and at port entrances and exits. Using striking colors (such as red and orange), they provide clear navigational boundary indications for ships during the day. Some buoys are also equipped with reflective devices or lighting to enhance visibility at night or in inclement weather (such as fog or rain), ensuring safe navigation.

[0003] However, existing PET buoy connection methods have significant drawbacks, making it difficult to meet the stability and convenience requirements of practical applications. The rope tying method is a relatively traditional connection method, requiring workers to thread ropes through the buoys sequentially or tie knots at pre-set simple attachment points to connect multiple buoys into the required length and shape. However, because the buoys are constantly submerged in water, the continuous impact of waves causes friction and relative displacement at the rope-buoy connection point, leading to gradual loosening and slippage of the ropes. Ultimately, this can easily result in the buoy detaching from the ropes. A detached buoy not only disrupts the integrity of the navigation warning system, causing ships to deviate from their course due to the inability to accurately identify channel boundaries, increasing the risk of running aground or striking reefs, but also allows the detached buoy to drift with the current, causing impact damage to the propellers, steering gear, and other equipment of passing vessels.

[0004] While the snap-fit ​​connection method, another common connection method, offers an improvement in connection speed compared to the rope binding method, it also has significant drawbacks. This method requires pre-setting specific-sized connecting holes or rings on the surface or inside of the float during the manufacturing process using specialized molds, to facilitate connection with plastic or metal snap-fits. This pre-setting step not only increases the complexity of the float manufacturing process and extends the production cycle but also raises production costs. Furthermore, the pre-set connecting holes or rings alter the original structural integrity of the float, reducing its impact resistance and sealing performance to some extent. Especially at the contact points between the metal snap-fit ​​and the connecting holes, prolonged immersion in water can easily lead to electrochemical corrosion, causing the snap-fit ​​to loosen and the connection to fail. More importantly, the snap-fit ​​connection method has significant limitations; it is completely unsuitable for ordinary PET floats without pre-set connecting holes or rings. Forcibly drilling holes or adding connecting rings to existing floats without pre-set structures is not only difficult but can also damage the float's structure, causing leakage and sinking, thus failing to achieve its normal buoyancy function.

[0005] In addition to the connection problem, the existing PET buoy fixing method is also seriously inadequate in terms of stability, which makes the buoy prone to tipping over and overturning on the water surface. There are many factors contributing to this problem. First, there are structural design flaws in the buoys themselves. Some buoys, in pursuit of lightweight design, use excessively thin shells or have an unreasonable center of gravity distribution, making it difficult for them to maintain balance when subjected to wave impacts or disturbances caused by ship navigation. In addition, the influence of external environmental factors cannot be ignored. Extreme weather and hydrological conditions such as strong winds, heavy rains, and tides generate more violent waves and currents, producing strong lateral thrust and upward buoyancy impacts on the buoys. When these external forces exceed the stability tolerance limit of the buoys, they will cause them to tip over or capsize. After a buoy tip over or capsizes, its surface warning colors, reflective devices, or lighting equipment will be obscured by the water, losing their navigational indication function. Ship operators will not be able to obtain accurate navigational information in a timely manner, which can easily lead to navigational accidents. At the same time, capsized buoys will also squeeze and collide with other buoys, causing buoy damage and further aggravating system failures, seriously affecting the normal operation of the entire waterway safety assurance system.

[0006] Therefore, this invention proposes an easily disassembled PET float device to solve the above problems. Summary of the Invention

[0007] In view of this, the technical problem to be solved by the present invention is to provide a PET float device that is easy to disassemble, so as to solve the problems existing in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a PET float device that is easy to disassemble, comprising: a float, and further comprising: a structural assembly group, an initial positioning unit group, and a self-adjusting snap-fit ​​stabilizing group;

[0009] The architecture assembly group is used to provide support for the installation of components such as the float, the initial positioning unit group, and the self-adjusting snap-fit ​​stabilization group.

[0010] The initial positioning unit group is suitable for quickly fixing the float when it is in its initial state, that is, before it is put into the water.

[0011] The self-adjusting snap-fit ​​stabilizing assembly is used to adaptively maintain the tightness of the float in water, reducing the occurrence of it tipping over, which is detrimental to practical use.

[0012] As an improvement, the architecture assembly includes a frustum base located below the float, with transverse connecting beams symmetrically fixedly connected inside the frustum base, and limiting slot blocks fixedly connected to the inner sidewalls of the beams;

[0013] The truncated cone base has circular surfaces on both the top and bottom, with the radius of the top surface being greater than the radius of the bottom surface.

[0014] As an improvement, a ring is fixedly connected to the outer ring surface of the truncated cone, and sliding grooves are symmetrically opened on the ring, with meshing grooves equidistantly opened in the sliding grooves;

[0015] A position adjustment block is slidably connected inside the sliding groove, and a fastening bolt is threaded onto the position adjustment block.

[0016] As an improvement, the initial positioning unit group includes a magnetic chuck symmetrically fixedly connected to the upper surface of the frustum base, a vertical rod is vertically movably inserted into the axis of the magnetic chuck, and an auxiliary hole is provided on the frustum base to assist the vertical movement of the frustum base.

[0017] A polygonal block is fixedly connected to the top of the vertical rod, and a pull ring is hinged to the polygonal block;

[0018] The inner wall of the truncated cone is symmetrically and fixedly connected to a guide cavity, and a magnetic block is fixedly connected inside the guide cavity.

[0019] As an improvement, the self-adjusting snap-fit ​​stabilizing assembly includes a main block fixedly connected between two transverse connecting beams;

[0020] The vertical rod has an oblique groove, and a horizontal rod is movably inserted into the main body block. The horizontal rod has a groove, and an oblique block is fixedly connected in the groove. The oblique position of the oblique groove and the oblique block is lower on the left and higher on the right.

[0021] As an improvement, each end of the transverse rod away from the magnetic block is fixedly connected with a snap-fit ​​ring, and the two snap-fit ​​rings are distributed overlappingly.

[0022] The bottom of the vertical rod is connected to an auxiliary ring, and a tension cable is fixedly connected to the auxiliary ring. A counterweight is fixedly connected to the end of the tension cable away from the auxiliary ring.

[0023] As an improvement, both the polygonal block and the end face of the transverse rod are made of magnetic material.

[0024] As an improvement, the snap-fit ​​ring is composed of a circular groove and a square groove, which together form the snap-fit ​​ring. The circular groove is adapted to the mounting head of the float, and the square groove is adapted to the mounting pipe diameter of the float. Specifically, the inner diameter of the circular groove > the outer diameter of the mounting head > the inner wall spacing of the square groove > the outer diameter of the mounting pipe.

[0025] As an improvement, the inner arc surface of the counterweight is adapted to the curvature of the inner cavity of the frustum.

[0026] Compared with the prior art, the present invention provides a PET float device that is easy to disassemble, and has the following beneficial effects:

[0027] 1. This invention, through the asymmetrical structural design of the frustum base where the radius of the upper surface is greater than the radius of the lower surface, and the assembly method where the inner arc surface fits into the inner arc surface of the counterweight, offers the following advantages based on mechanical principles, structural adaptability, and practical application requirements:

[0028] Precise control of the device's center of gravity ensures vertical stability: This truncated cone base design achieves precise control and stable locking of the device's center of gravity through structural optimization. On one hand, the structure, with a "top surface radius greater than bottom surface radius," gives the truncated cone base a "wider at the top and narrower at the bottom" shape, naturally shifting its center of gravity towards the bottom area. On the other hand, the sliding contact between the inner arc surface of the truncated cone base and the inner arc surface of the counterweight further concentrates the weight of the counterweight onto the center of the bottom of the truncated cone base. Together, these two factors ensure that the overall center of gravity of the entire PET float device remains stably located at the bottom center of gravity of the truncated cone base, forming a mechanical structure similar to a "roly-poly toy." This center of gravity distribution characteristic fundamentally avoids the device's tilting tendency caused by a shift in the center of gravity. Even when the water surface sways, the concentrated gravity at the bottom can automatically restore the vertical attitude, ensuring that the float always floats stably and upright on the water surface, providing continuous and reliable attitude assurance for the navigation warning function.

[0029] Enhancing resistance to external interference and mitigating the effects of extreme environments: In practical applications in the maritime industry, buoys must withstand the impact of complex external factors such as wave impact, strong wind disturbance, and tidal changes over long periods. The truncated cone base design significantly improves the device's resistance to interference. First, the "wider at the top and narrower at the bottom" truncated cone structure disperses the horizontal impact force through the larger force-bearing area of ​​the top surface when facing wave impact, while the narrower bottom surface reduces the drag force of the water flow on the bottom, reducing the impact of water flow disturbance on the device's stability. Second, the stable bottom center of gravity, combined with the weight of the counterweight, gives the device a stronger anti-overturning moment—when extreme external forces such as strong winds and giant waves attempt to push the buoy to a tilted state, the concentrated gravity at the bottom generates a reverse restoring moment, offsetting the tilting tendency caused by the external force and preventing the device from overturning due to external forces exceeding the stability limit. Compared to existing buoy structures, this truncated cone base design allows the buoy to remain stable in harsh environments such as heavy rain, strong typhoons, and rapid currents, significantly improving the device's environmental adaptability and service life.

[0030] Compatible with float functionality without compromising core performance: This truncated cone base design enhances stability while fully considering the compatibility of the PET float's core functions, avoiding any impact on the float's normal use due to structural optimization. The "wider at the top, narrower at the bottom" shape of the truncated cone base allows for efficient adaptation to the float body—the larger radius of the top surface provides ample support area for the float body, ensuring stability when the float is connected to the truncated cone base, while not obstructing the float's warning colors, reflective devices, or lighting equipment; the narrower bottom surface reduces the device's immersion depth in water, preventing excessive water resistance or affecting the float's normal buoyancy performance due to an overly large bottom structure. Furthermore, the truncated cone base's structural design does not alter the float's original sealing and impact resistance performance. Instead, the stable support structure reduces stress concentration caused by tilting and collisions in the float body, indirectly improving the float body's structural durability, achieving the dual goals of "enhanced stability" and "guaranteed core functionality."

[0031] 2. The ring design of this invention offers the following advantages:

[0032] Precisely guided position adjustment blocks enhance adjustment efficiency and accuracy: The primary function of the ring is to provide a stable and precise guide path for the position adjustment blocks, overcoming the operational difficulties caused by "unguided adjustment" or "fuzzy guidance" in traditional float connections. On one hand, the ring, through its pre-set annular track structure, defines a fixed trajectory for the movement of the position adjustment blocks, preventing them from shifting, jamming, or misaligning during operation. This ensures the blocks slide smoothly along the ring's axis, significantly reducing the difficulty of operation for staff. On the other hand, the annular guide structure allows for stopping and fixing at larger angles and positions, enabling staff to quickly find the optimal position for the float without repeated calibration. Compared to the traditional rope binding method ("difficult to fine-tune after knotting") and the buckle connection method ("limited fixed points and inflexible adjustment"), the ring guide design improves the efficiency of float connections.

[0033] Acting as a reinforcing rib of the truncated cone base, the ring significantly enhances structural rigidity and damage resistance: The ring additionally functions as a "reinforcing rib" for the truncated cone base, structurally strengthening its load-bearing capacity and impact resistance, thus addressing the shortcomings of existing truncated cone bases that suffer from insufficient rigidity due to "lightweight design." On one hand, the ring is tightly integrated with the truncated cone base through a wraparound assembly, forming a support structure similar to a "ring skeleton," preventing cracking and deformation of the truncated cone base under stress. On the other hand, the ring's ring structure enhances the torsional resistance of the truncated cone base—when the truncated cone base is subjected to lateral torque (such as the torsional force generated by a water vortex), the ring can resist the torque through its own rigidity, preventing the truncated cone base from twisting and deforming, ensuring that its "wider at the top and narrower at the bottom" center of gravity stability structure is not compromised, and significantly extending the service life of the device.

[0034] Simplified structural design achieves the integrated advantage of "one component, multiple uses": The multi-functional design of the ring simplifies the overall structure of the PET float device, avoiding the "component redundancy" problem caused by functional separation. Traditional float devices require separate components such as guide rails and independent reinforcing ribs to achieve "position adjustment" and "structural reinforcement," increasing assembly steps and manufacturing costs, and leading to decreased overall reliability due to poor compatibility between components. The ring in this invention integrates "guidance" and "reinforcement" functions, simultaneously meeting both core requirements without the need for additional components. This integrated design reduces the number of parts in the device, balancing "functional comprehensiveness" and "structural simplicity," facilitating large-scale production and subsequent maintenance.

[0035] 3. This invention addresses the key optimizations of existing rope fixing methods that suffer from "easy displacement and instability." Through its synergistic effect with the snap-fit ​​ring, it adds a limiting groove to the PET float device, providing reliable protection for float fixing in terms of fixing structure, anti-interference capability, and safety of use. This offers the following benefits:

[0036] Locking the snap-fit ​​ring position eliminates the risk of relative displacement: The limiting block, through its pre-designed groove structure, provides a "physical limit" for the snap-fit ​​ring, achieving precise locking of its position. Once the snap-fit ​​ring has secured the float, it embeds into the pre-designed slot of the limiting block, forming a constraint that ensures the snap-fit ​​ring and the float remain relatively stationary. Compared to existing rope fixing methods that rely solely on rope tension for fixation, which are prone to loosening and slippage due to water action and wave impact, the limiting block's physical limiting structure fundamentally eliminates the risk of relative displacement. This ensures the snap-fit ​​ring's fixation of the float remains stable over the long term, preventing fixation failure due to time or external interference, and guaranteeing the float remains in its pre-designed working position.

[0037] To avoid the risk of buoy detachment and ensure navigational safety: Existing rope fixing methods are prone to buoy detachment due to "relative displacement causing rope loosening," which can compromise the integrity of the navigational warning system and increase the risk of ships running aground or hitting reefs. The limiting block, however, ensures the stability of the locking ring, preventing buoy detachment at its source. Firstly, the limiting block locks the locking ring in place, ensuring a stable clamping force on the buoy and preventing weakening due to displacement. Secondly, even with slight wear or fatigue of the locking ring, the limiting block maintains the relative position of the buoy and the locking ring through physical restraint. This stable fixing ensures the buoy remains in the preset navigational warning position, allowing its surface warning colors, reflective devices, or lighting equipment to continue functioning, providing clear and accurate navigational information to ship operators, preventing navigational accidents caused by buoy detachment, and ensuring the reliable operation of the entire navigational warning system.

[0038] 4. The float fixing method of this invention, which uses the shape design of the snap-fit ​​ring and the lateral offset locking, relies on the innovative structure of the snap-fit ​​ring's "combination of circular and square grooves." This breaks through the technical limitations of existing snap-fit ​​connection methods that "rely on pre-set connection holes / rings on the float." It brings breakthrough advantages to PET float devices from the dimensions of process simplification, improved adaptability, and optimized operation, and has the following benefits:

[0039] By eliminating the need for pre-processing steps in float assembly, the production process is simplified and costs are reduced: The lateral offset fixing method abandons the core requirement of the existing snap-fit ​​connection method, which "requires pre-setting connecting holes or connecting rings during the float assembly stage." It directly achieves float restraint and fixation through the groove structure of the snap-fit ​​ring, significantly simplifying the float manufacturing process. On the one hand, float production does not require the design of additional special molds to process connecting holes / rings, saving time and costs associated with mold development and debugging. It also reduces key processes such as "drilling / adding rings," shortening the float production cycle. On the other hand, it avoids the damage to the float structure caused by pre-setting connecting holes / rings. In traditional snap-fit ​​connections, the opening of connecting holes often leads to a decrease in the strength of the float shell and impaired sealing performance (e.g., leakage is likely at the drilled area). The lateral offset fixing method, however, does not require modification of the float body, preserving the original corrosion resistance, impact resistance, and sealing performance of the float, reducing the float scrap rate due to structural defects. From a cost perspective, eliminating pre-processing steps reduces the unit production cost of floats, saving companies significant manpower and equipment investment.

[0040] Overcoming the limitations of float structure and achieving broad adaptability: Existing snap-fit ​​connection methods can only be used with dedicated floats that have "pre-set connection holes / rings," and are completely unusable for ordinary PET floats or irregularly shaped floats without pre-set structures, resulting in severe application limitations. The lateral offset fixing method, through the operational logic of "place first, then lock in offset," achieves broad adaptability to floats with different structures. The circular groove design of the snap-fit ​​ring is compatible with floats within a certain diameter range; as long as the float diameter matches the inner diameter of the circular groove, it can be smoothly placed into the groove, regardless of whether the float surface has a connecting structure. This adaptability characteristic of "not relying on the float's pre-set structure" allows one set of snap-fit ​​rings to be used for float fixing in various scenarios, eliminating the need to design separate connecting components for different floats, significantly improving the device's versatility and reusability.

[0041] Simplifying the installation process and improving efficiency and convenience: The lateral offset fixing method significantly reduces the complexity of float installation and improves on-site work efficiency through a simple two-step operation. Specifically, the first step, "placing the float," simply involves aligning the float with the circular grooves of the two overlapping snap-fit ​​rings and gently inserting it, completing the initial placement without the need for precise alignment of the connection holes and clips. The second step, "lateral offset locking," simply involves pushing the snap-fit ​​rings horizontally, allowing the float to move from the circular groove into the square groove during structural misalignment. The corners of the square groove and the surface of the float then press against each other to achieve locking. The entire process requires no tools and can be completed by a single person. Compared to the complex steps of the existing snap-fit ​​connection method, which requires aligning the connection holes, inserting the clips, and tightening the fasteners, the lateral offset fixing method shortens the operation time. Especially in water-based work environments, workers no longer need to bend over or work underwater for extended periods, reducing labor intensity and safety risks.

[0042] Enhanced stability and prevention of connection failure over long-term use: The lateral misalignment fixing method utilizes the principle of "physical compression locking" to achieve a more stable fixation than snap-fit ​​connections, effectively preventing connection failures over time. Firstly, the square groove's contact with the float is a "surface contact," resulting in a larger contact area and more uniform clamping force compared to the "point contact" or "line contact" of snap-fit ​​connections. This reduces localized stress concentration on the float's surface, preventing surface wear or deformation due to prolonged stress. Secondly, the lateral misalignment structure possesses "anti-loosening" characteristics; external forces such as wave impact and ship disturbance make it difficult for the snap-fit ​​rings to misalign in the opposite direction. Even under prolonged immersion in water, there will be no loosening caused by snap-fit ​​corrosion. This fixing method offers long-term stability advantages.

[0043] 5. Through the design and assembly of the overall components, this invention offers the following advantages:

[0044] Achieving portable disassembly significantly improves work efficiency: The collaborative cooperation between components achieves a breakthrough in portability in terms of both disassembly process and operational difficulty. On the one hand, the initial positioning unit group can quickly release the float from its initial fixed state without repeatedly disassembling the connectors. On the other hand, the self-adjusting snap-fit ​​stabilizing group has a "reverse self-loosening" characteristic. However, when disassembly is required, simply moving the snap-fit ​​ring in the lateral reverse direction allows the float to return from the square slot to the round slot, releasing it from the locked state. Combined with the modular support structure of the structural assembly group, workers can directly remove the float from the device. The entire disassembly process requires no tools, effectively improving efficiency compared to traditional rope binding and snap-fit ​​connection methods.

[0045] The all-mechanical component design reduces maintenance difficulty and cost: The device adopts a "no electrical control system, all-mechanical component" structural solution, reducing maintenance needs from the source and lowering later operation and maintenance costs. First, the mechanical components have stronger environmental tolerance—there is no need to worry about short circuit damage to electronic components caused by water immersion or humid environments, nor is there any need to deal with the impact of extreme temperatures (such as high temperature exposure or low temperature freezing) on ​​the performance of the electrical control system; second, maintenance operations are simpler; staff do not need professional electronic repair skills, they only need to visually inspect the wear of mechanical components (such as the fit of the snap ring, the integrity of the positioning unit group), and directly replace the worn parts, without performing complex circuit testing or program debugging; finally, the replacement cost of parts is lower, the manufacturing cost of mechanical parts (such as snap rings, positioning buckles) is much lower than that of electrical control modules (such as sensors, controllers), and they are highly versatile, one set of parts can be adapted to multiple devices, reducing spare parts inventory pressure.

[0046] Enhancing Device Reliability and Environmental Adaptability: The all-mechanical structure and multi-component collaborative design jointly enhance the device's reliability and adaptability in the complex environments of the maritime industry. On the one hand, the mechanical components exhibit superior shock and vibration resistance. When faced with wave impacts and vibrations caused by ship navigation, the mechanical connection structures (such as snap-fits and latches) are less prone to loosening or damage, while the wiring interfaces and sensor probes of the electronic control system are prone to poor contact under severe vibration. On the other hand, the non-electronic design avoids the risk of "power outage failure." Traditional float devices with electronic control will lose functionality if the battery is depleted or the wiring fails. The mechanical fixing and disassembly functions of this invention rely entirely on the physical structure, requiring no external power supply and maintaining normal operation under any circumstances. Furthermore, the mechanical components are more resistant to water pollution. Even in turbid waters containing oil and silt, the movement of the mechanical structure is less affected by impurities (such as the sliding groove of the snap-fit ​​ring, which can be naturally flushed away by water flow), while the sensors of the electronic control system are easily covered by oil and silt, leading to functional failure.

[0065] Please refer to Figure 3 , Figure 4 , Figures 7 to 9 As shown:

[0066] To address the problems mentioned in the technical solutions, this application provides an easily detachable PET float device, comprising: a float 1, and further comprising: a structural assembly group 2, an initial positioning unit group 3, and a self-adjusting snap-fit ​​stabilizing group 4;

[0071] The upper surface of the truncated cone base 201 has an opening for mounting the float 1.

[0072] The limiting groove block 203 is used to limit the movement of the snap ring 405, reduce its swaying / relative displacement at the fixed point with the float 1, and avoid slippage and detachment of the rope and the fixed point with the float 1 in the water, unlike other fixing methods.

[0073] In addition to providing a moving guide for the position adjustment block 207, the ring 204 can also be used as a reinforcing rib for the frustum base 201 to increase its structural rigidity.

A vertical rod 302 is vertically movably inserted into the axis of the magnetic chuck 301. An auxiliary hole is provided on the truncated cone base 201 to assist in the vertical movement of the truncated cone base 201. A polygonal block 303 is fixedly connected to the top of the vertical rod 302. A pull ring 304 is hinged on the polygonal block 303. A guide cavity 305 is symmetrically fixedly connected to the inner wall of the truncated cone base 201. A magnetic block 306 is fixedly connected inside the guide cavity 305.

[0081] Both the magnetic chuck 301 and the polygon block 303 have corrosion-resistant coatings on their outer surfaces.

[0082] Polygon 303 is made of magnetic material.

[0083] The presence of the pull ring 304 facilitates the operator's operation of lifting the vertical rod 302.

[0084] The magnetic block 306 can magnetically attract the side end face of the horizontal rod 403 made of magnetic material.

[0087] in:

[0088] The self-adjusting snap-fit ​​stabilizing assembly 4 is used to adaptively maintain the tightness of the float 1 in water, reducing the occurrence of its tipping over, which is detrimental to practical use.

[0089] The main block 401 has horizontal and vertical column grooves, which are arranged in a cross shape.

[0090] The inclined groove 402 is compatible with the inclined block 404.

[0091] The snap ring 405 is composed of a circular groove and a square groove, which together form the snap ring 405. The circular groove is adapted to the mounting pipe head of the float 1, and the square groove is adapted to the mounting pipe diameter of the float 1. Specifically, the inner diameter of the circular groove > the outer diameter of the mounting pipe head > the inner wall spacing of the square groove > the outer diameter of the mounting pipe.

[0092] The inner arc surface of the counterweight 408 is adapted to the curvature of the inner cavity of the frustum base 201.

[0093] The counterweight 408 can be used to pull the vertical rod 302 to maintain the two locking rings 405 fastening the float 1, reducing the loosening of the overall equipment under water surface swaying; and its counterweight 408 itself is located at the bottom of the truncated cone 201, and the shape of the truncated cone 201 helps to stabilize the overall center of gravity of the device, reducing the probability of the overall equipment overturning under water waves.

[0094] The working principle of all the content in the above embodiments is as follows:

[0095] In the initial state:

[0096] The fastening bolt 208 is not screwed into the engagement groove 206, and the position adjustment block 207 can slide in the sliding groove 205; the polygonal block 303 is not magnetically attracted to the magnetic chuck 301; the side end face of the transverse rod 403 is not magnetically attracted to the magnetic block 306; the side of the snap ring 405 has not moved into the limiting groove 203, and the two snap rings 405 are in an overlapping state.

[0097] It should be noted that the device operates in three stages: initial fixing of float 1 before it enters the water (initial positioning unit group 3); initial adjustment of the connection position of adjacent devices, i.e., determining the connection point between adjacent floats 1 after entering the water (structure group 2); and adaptive protection of the overall stability of the device after entering the water (self-regulating snap-fit ​​stability group 4).

[0098] When in use, the connection points between adjacent floats 1 after entering the water need to be precisely adjusted; specifically, the rope is first tied to the fastening bolt 208 of the adjacent device to form a series connection between devices without floats 1.

[0099] Then, float 1 is placed into the circular groove of the overlapping snap ring piece 405 through the mounting opening on the upper surface of the frustum base 201. (Refer to the attached diagram.) Figure 1 and appendix Figure 2 After placement, press down on the polygonal block 303 to move it into the inner groove of the magnetic chuck 301 and attract it magnetically. During this process, the polygonal block 303 will move downwards along with the vertical rod 302, that is, into the frustum base 201. (Refer to the attached diagram.) Figure 8 ;

[0100] For further details, please refer to the appendix. Figure 6 and appendix Figure 10 As the vertical rod 302 moves downward, the inclined block 404, which slides and adapts to the inclined groove 402, will move the horizontal rod 403 towards the position of the guide cavity 305 as the vertical rod 302 moves downward; in the attached figure, this movement is to the right. As the horizontal rod 403 moves, the right end of the horizontal rod 403, made of magnetic material, will move laterally to the right under the guidance of the inner cavity of the guide cavity 305, and finally magnetically attracts the magnetic block 306. At this point, the polygonal block 303 is magnetically attracted to the magnetic chuck 301, and the end face of the horizontal rod 403 is magnetically attracted to the magnetic block 306. Under the above magnetic attraction, the vertical rod 302 and the horizontal rod 403 are in a fixed state and no longer move.

[0101] Furthermore, during the movement of the vertical rod 302 and the horizontal rod 403, the horizontal rod 403 moves along with the snap-fit ​​ring 405 fixedly connected to it. In this design, the initial positioning unit group 3 and the self-adjusting snap-fit ​​stabilizing group 4 are symmetrically arranged. Therefore, driven by the symmetrically moving horizontal rods 403, the snap-fit ​​rings 405 on the two horizontal rods 403 will change from an overlapping state. (See attached diagram.) Figure 11 At this point, the installation diameter of float 1 will be limited by the square grooves of the two snap-fit ​​rings 405; that is, the fixing of float 1 is now complete.

[0102] Furthermore, after repeating the above operations multiple times, a series of devices with floats 1 are obtained. When the series of floats 1 is placed in the water, the connection points between adjacent devices / buoys 1 can be determined. Specifically, according to the required navigation guidance route, the relative position of the position adjustment block 207 in the sliding groove 205 is adjusted, as shown in the attached diagram. Figure 3 and appendix Figure 9 When the float is slid to the relative position, tighten the fastening bolt 208. The fastening bolt 208 will enter the engagement groove 206 during tightening, thereby fixing the position of the originally slidable position adjustment block 207. At this point, the navigation warning guidance composed of the float 1 is completed.

[0103] Furthermore, after the device with float 1 is submerged in water, the counterweight 408 will move to the bottom of the inner cavity of the frustum 201 under its own weight, thereby ensuring that the frustum 201 is in a vertically stable state. In addition, the vertical rod 302, which is connected to the counterweight 408 through the auxiliary ring 406 and the traction cable 407, will be subjected to a downward pulling force under the weight of the counterweight 408. This force can effectively ensure that the locking ring 405 that interlocks with the float 1 is in a stable state.

[0104] Furthermore, when the water body is disturbed, the entire device will shake under the action of the water body. However, during the shaking, due to the weight of the counterweight 408 itself, and because it is located at the bottom of the entire device, the center of gravity of the device with the float 1 can be effectively reduced. With the assistance of the cone-shaped frustum 201, it can adapt to the shaking and quickly restore a stable state.
