Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of marine equipment, and particularly relates to a floating body, a floating body connecting structure and a floating body manufacturing method. BACKGROUND

[0002] With the development of marine resources, large floating structures are increasingly widely used. The overall safety and durability of a large floating structure, which is usually connected by a plurality of modular floating body units, largely depends on the performance of the connecting device.

[0003] In the prior art, the floating body is usually hollow or solid with low-density material, and the corresponding connecting mode mainly includes rigid connection and hinged connection. However, the above floating body and connecting structure lack degrees of freedom, resulting in weak bending and torsional resistance at the connection, which is prone to brittle fracture or plastic hinge under long-term alternating loads, and has insufficient reliability. In the improved technology, the spherical hinge connection has a complex mechanical structure, resulting in high manufacturing requirements and high cost. More importantly, in the high-salinity and high-humidity marine corrosion environment, the precise movement pair of the spherical hinge is prone to be stuck due to corrosion or attachment of marine organisms, losing its activity function. Meanwhile, there are problems of great difficulty in maintenance and repair and high cost.

[0004] In summary, the prior art cannot provide a floating body and connecting structure that can buffer dynamic load and reduce impact while controlling cost. SUMMARY

[0020] The stiffness of each group of orthogonal buffer structures is not the same, and the stiffness of the orthogonal buffer structure on the side close to the damper is smaller than the stiffness of the distal orthogonal buffer structure.

[0021] Further, the flexible floating body shell has an ellipsoidal structure, and the ratio of the length of the major axis to the length of the minor axis ranges from 1.5 to 3.

[0022] On the other hand, the application also provides a floating body connecting structure for connecting the floating body; the floating body connecting structure comprises a cable hole, a first cable and a second cable;

[0023] A plurality of cable holes are arranged on the flexible floating body shell; the cable hole is a through hole structure, and the hole is arranged along the long side or the major axis direction of the flexible floating body shell, and the cable hole is not in communication with the inside of the floating body;

[0024] The two ends of the second cable are connected with the end portions of the adjacent first cables respectively, and each second cable penetrates through a corresponding cable hole.

[0025] In another aspect, the application provides a floating body manufacturing method, comprising:

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0048] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0049] It should also be understood that the relative relationships indicated by terms such as "longitudinal" and "lateral" are descriptions based on the shape characteristics of the device or structure in actual application, for the purpose of facilitating the description of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific position, and therefore should not be construed as a limitation of this application.

[0050] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0052] It is worth noting that, unless otherwise specified, the methods used in this application are conventional methods; and the raw materials and equipment used are, unless otherwise specified, conventional commercially available products.

[0053] On the one hand, this application provides a structural schematic diagram of a float mounting position, including a float and a float connecting structure, such as... Figure 1 , Figure 2 and Figure 3 As shown. The floating body includes: a flexible floating shell 1, a damper 2, and multiple sets of orthogonal buffer structures.

[0054] In this embodiment, the deformation performance of the flexible floating shell 1 is based on the material used. Optionally, the flexible floating shell 1 in this embodiment is made of rubber composite material, which provides both elastic deformation capability and sufficient mechanical strength. Furthermore, the flexible floating shell 1 has an ellipsoidal structure with a hollow interior forming a cavity. The ratio of the major axis length to the minor axis length of the flexible floating shell 1 ranges from 1.5 to 3; preferably, the ratio is 2, i.e., the major axis length is twice the minor axis length. This optimized ratio design ensures that when the floating body is under axial tension, the stress is evenly distributed and converted into efficient radial compressive deformation.

[0055] A damper 2 is installed laterally inside the flexible floating body shell 1. In this embodiment, the damper 2 is a piston-type viscous damper, which is distributed along the minor axis of the flexible floating body shell 1 and installed in the middle of the floating body. The two ends of the damper 2 are fixedly connected to the inner wall of the flexible floating body shell 1 through long strip-shaped mounting pads 4. The damper 2 is used to enhance the energy dissipation capacity of the floating body and provide a certain supporting force.

[0056] Orthogonal buffer structures are installed inside the flexible floating body shell 1, and multiple sets of orthogonal buffer structures are symmetrically distributed on both sides of the damper 2. In this embodiment, multiple sets of orthogonal buffer structures are distributed along the long axis of the flexible floating body shell 1. Optionally, in this embodiment, each set of orthogonal buffer structures includes two buffer elastic elements, specifically selected as columnar springs 3, and the axes of the two columnar springs 3 in each set are perpendicular to each other, forming an orthogonal structure. In each set of orthogonal buffer structures, the axis of one columnar spring 3 is kept parallel to the axis of the damper 2. Further, in this embodiment, two sets of orthogonal buffer structures are provided on each side of the flexible floating body shell 1, and in the orthogonal buffer structure adjacent to the damper 2, the columnar spring 3 adjacent to the damper 2 is arranged in parallel with it, that is, the adjacent columnar spring 3 and the damper 2 share the long strip-shaped mounting pad 4 at the end. Other columnar springs 3 are provided with mounting pads 4 at their ends, and are fixedly connected to the interior of the flexible floating body shell 1 through the mounting pads 4. Furthermore, the stiffness of each group of orthogonal buffer structures is not the same, and the stiffness of the orthogonal buffer structure on the side closer to damper 2 is less than the stiffness of the orthogonal buffer structure on the far side (away from the damper). That is, in this embodiment, the spring stiffness of the orthogonal buffer structures on both sides of damper 2 is less than the spring stiffness of the orthogonal buffer structure on the far side of the long axis.

[0057] Therefore, a spring with lower stiffness is installed on the inner side to cope with normal waves, while a spring with higher stiffness is installed on the outer side to resist extreme storms, realizing a multi-stage buffering mechanism that combines soft start and hard protection. The damper 2 is located in the central axis area of ​​the structure and works in parallel with the spring group, significantly enhancing the energy dissipation capacity and deformation resistance of the device. Furthermore, through the compression deformation of the hollow ellipsoidal rubber body and the synergistic effect of the multi-stage spring group, excellent buffering and energy absorption effects are achieved, effectively reducing dynamic loads. In different embodiments, the device performance can be flexibly customized to adapt to different marine environmental conditions by adjusting the composition and / or structural dimensional parameters of the flexible floating shell 1 and the spring stiffness. The overall structure is simple and reliable, easy to maintain, and has good engineering application prospects.

[0058] Furthermore, in this embodiment, the mounting pad 4 not only provides a mounting base for internal components, but also... Figure 4 As shown, a multi-layer structure is adopted; specifically, the mounting pad 4 includes a substrate 401 and a data unit 402. In the substrate 401, there are a power generation layer 4011, an insulating layer 4012 and a sensor layer 4013.

[0059] In this embodiment, the power generation layer 4011, the insulation layer 4012, and the sensor layer 4013 are stacked sequentially along the mounting axis of the columnar spring 3 or the damper 2, with the sensor layer 4013 located on the outermost side, close to the inner wall of the flexible floating body shell 1. The power generation layer 4011 uses a PZT (lead zirconate titanate) piezoelectric ceramic sheet, generating electricity using the mechanical stress generated by the deformation of the connector during operation; the insulation layer 4012 is made of flexible insulating material, ensuring that power generation and sensor monitoring do not interfere with each other; the sensor layer 4013 uses a high-precision thin-film pressure sensor for real-time and accurate measurement of interface pressure. Furthermore, the outer layer of the substrate 401 in this embodiment is made of a rigid material, with an internal cavity for mounting the aforementioned power generation layer 4011, insulation layer 4012, and sensor layer 4013, and is potted with polyurethane or epoxy resin. The substrate 401 is used to connect and support the damper 2 and the orthogonal buffer structure, so its bottom surface is machined into a contoured curved surface to fit the interior of the flexible floating body shell 1 in this embodiment and level the mounting position. It should be noted that the "leveling" referred to in this embodiment means that the mounting position of the internal components provided by each mounting pad 4 is perpendicular to the radial direction of the cross-section of the flexible floating body shell 1, so that the damper 2 and each columnar spring 3 are distributed radially, and by adjusting the position of the mounting pad 4, the intersection of the projections of each group of orthogonal buffer structures in the long axis direction is located on the long axis.

[0060] Furthermore, the sensor layer 4013 is connected to a data unit 402, which includes a data acquisition unit, a data processing unit, a power supply circuit, and a communication module. In this embodiment, one or more data units 402 can be provided to receive, process, and forward pressure data from each sensor layer 4013. One example is: the data acquisition unit is a data acquisition card; the data processing unit is a miniaturized microcontroller module, such as a microcontroller for wearable devices; and the communication module is a wireless communication module. The input interface of the data acquisition card is connected to the thin-film pressure sensor via a wire, and the output interface is connected to the miniaturized microcontroller module; the communication interface of the miniaturized microcontroller module is connected to the wireless communication module, which transmits the acquired pressure data to the receiving terminal of an external device; the input end of the power supply circuit is connected to a piezoelectric ceramic sheet, and the output end is connected to the thin-film pressure sensor, the miniaturized microcontroller module, and the wireless communication module, respectively.

[0061] The aforementioned intelligent mounting pad 4 enables mechanical energy harvesting and state self-sensing, thereby improving the intelligence level of the floating body.

[0062] On the other hand, this embodiment also provides a floating body connection structure based on the above-mentioned floating body, such as... Figures 1-3 As shown, the floating body connection structure includes a cable hole, a first cable 5, and a second cable 6.

[0063] The flexible floating body shell 1 has multiple cable holes, with four cable holes being used as an example. Each cable hole is a through-hole structure, with the hole arranged along the long axis of the flexible floating body shell 1. The cable hole does not communicate with the interior of the floating body; that is, the cable hole only penetrates the outer layer of the shell. This design does not compromise the integrity of the flexible floating body shell 1 and improves the internal sealing performance.

[0064] Four second cables 6 are provided, with each second cable 6 having its two ends connected to the ends of the adjacent first cables 5, and each second cable 6 passing through a corresponding cable hole.

[0065] In this embodiment, a single first cable 5 is used to connect a float, while four second cables 6 clamp the float at multiple points. This enhances the connection stability of the float and reduces alternating loads through the combined action of the multiple second cables 6. Furthermore, the connection structure in this embodiment can be fixed using a single cable. The first cable 5 has a multi-strand winding structure. During the winding process, the winding stops at a preset position, and the single strand of cable serves as the second cable 6, passing through the cable hole of the float. The winding then continues to form the first cable 5, thus maintaining the integrity of the cable and improving the overall stability and reliability.

[0066] Working principle:

[0067] When the float in this embodiment is subjected to axial load due to the movement of the wave relative to the connecting mechanism, the load is transmitted through the first cable 5 and the second cable 6, thereby radially compressing the flexible float shell 1.

[0068] (1) Mechanical buffering and energy dissipation: The column spring 3 undergoes elastic deformation to store energy; the damper 2 generates damping force synchronously, dissipates kinetic energy, and suppresses vibration.

[0069] (2) Status perception and energy harvesting: The pressure acting on the self-powered intelligent mounting pad 4 is monitored in real time by its sensor layer 4013, while its power generation layer 4011 converts part of the mechanical energy into electrical energy.

[0070] (3) Data self-powered transmission: The collected electrical energy drives the data unit 402 to work and wirelessly transmit the monitored pressure, status and other information.

[0071] The entire system realizes a complete closed loop from mechanical energy absorption and conversion to state information perception and transmission, without the need for external power supply, and achieves self-powered intelligent monitoring.

[0072] Furthermore, this embodiment also provides a method for manufacturing a float based on the above-mentioned float, which includes the following steps:

[0073] First, based on the processing dimensions of the float, a split mold with an interlocking structure is used on the end face of the machining cavity. In this embodiment, the split mold structure conforms to the longitudinal section of the flexible float shell 1, and preferably is split vertically to facilitate the vertical placement of the damper 2 within the lower shell. Furthermore, the interlocking structure in this embodiment is a mortise and tenon structure, which can be designed as a dovetail mortise and tenon structure or a Z-groove mortise and tenon structure.

[0074] The flexible floating body shell 1 is made of rubber-fiber composite material. Thus, it is vulcanized in two separate molds and obtained as a split flexible floating body shell after demolding; during the vulcanization process, the parting surface of the split flexible floating body shell simultaneously forms an interlocking structure.

[0075] The damper 2 and the multiple sets of orthogonal buffer structures are fixedly connected to the corresponding mounting pads 4 respectively; then, the damper 2 and the multiple sets of orthogonal buffer structures are fixedly installed in the split flexible floating body shell on the lower side.

[0076] Before the snap-fit ​​assembly, a high-performance marine-environment rubber adhesive is applied to the parting surface of the split flexible floating body shell. As a result, the adhesive fills the micro-gaps during assembly and forms a strong chemical bond after curing.

[0077] Afterwards, refer to Figure 5 As shown, two separate flexible floating body shells are pressed and fastened together using a mechanical pressing fixture. Through compression deformation at the parting surface, the interlocking structures on both sides are embedded into each other. When the aforementioned interlocking structure is a dovetail tenon and mortise structure, the joint surface forms as shown... Figure 6 The joint shown; when the aforementioned interlocking structure is a Z-groove mortise and tenon structure, the joint surface forms as shown. Figure 7 The seam shown. Regardless of the type of interlocking structure chosen, the two separate flexible floating shells can be mechanically interlocked, effectively resisting pull-out and shear forces, forming the main load-bearing path of the connection. A high-performance marine environment rubber adhesive is applied, which fills the microscopic gaps during assembly and forms a strong chemical bond after curing. This, together with the high-performance marine environment rubber adhesive, provides both mechanical and chemical protection, thus obtaining the floating body.

[0078] Furthermore, although the mechanical interlocking achieved by the aforementioned mortise and tenon structure provides the main connection strength and is reinforced by adhesive, this embodiment also requires enhanced sealing of the joints to ensure the reliability and long-term watertightness of the float; specifically, after the aforementioned snap-fit ​​assembly, as... Figure 8Furthermore, a continuous sealing groove is machined at the joint of the parting surface. After the fastening assembly is secure, an annular sealing groove is machined along the parting surface by cutting or grinding. The sealing groove is a strip that surrounds the parting surface of the float, and the width of the sealing groove is greater than the width of the tenon and mortise joint area. Finally, polysulfide sealant or a similar flexible sealing material is injected into the sealing groove to form an additional environmental protection layer 7.

[0079] Furthermore, in this embodiment, the damper 2 and the mounting pads 4 of the multiple sets of orthogonal buffer structures are fixedly connected to the inner wall of the flexible floating body shell 1 by adhesive bonding. Since the damper 2 only has one end of the mounting pad 4 glued and fixed before the fastening assembly, and the multiple sets of orthogonal buffer structures only have one end of the mounting pad 4, or half of the contact surface of the mounting pad 4 is glued to the lower split flexible floating body shell, this embodiment also performs a pre-coating process on the un-glued mounting pad 4 or the un-glued contact surface of the mounting pad 4 before the fastening assembly, and after the fastening assembly, the flexible floating body shell 1 is squeezed by tooling to make the mounting pad 4 glued and fixed to the upper split flexible floating body shell.

[0080] Finally, it should be noted that the above content is only used to illustrate the technical solution of this application, and is not intended to limit the scope of protection of this application. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this application shall not depart from the substance and scope of the technical solution of this application.
