Description

Technical Field

[0001] This invention belongs to the technical field of marine floating photovoltaic foundation structure, and in particular relates to the design of a multi-body connection and anti-collision device for a floating structure. Background Technology

[0002] Photovoltaic resources are a renewable and clean energy source with irreplaceable advantages over traditional fossil fuels. While onshore photovoltaic technology has matured, my country urgently needs to expand the development of offshore photovoltaic systems, broaden existing photovoltaic infrastructure, improve its energy structure, and meet its growing energy demands.

[0003] Domestically, ground-mounted photovoltaic (PV) structures are the mainstay. The increase in PV installed capacity is affected by grid absorption and resource allocation, and inland PV resources are not being fully utilized and developed. Coastal areas have even greater electricity needs, and onshore PV occupies more land resources, resulting in lower cost-effectiveness. Floating PV systems, on the other hand, save land resources and offer advantages that allow for integration with industries such as aquaculture and tourism development. These advantages are increasingly favored by PV project developers and technicians, making them a popular direction for PV power plant development both domestically and internationally.

[0004] Current research and practice in various countries have shown that, with the increasing demands for floating photovoltaic structures, the area and size of individual photovoltaic power generation units are gradually increasing. This presents challenges to structural reliability and transportation for individual support structures, making modular units a better solution. However, during the modular assembly and installation process, collisions between individual floating components can easily cause structural damage, increasing the failure rate and reducing the stability of offshore photovoltaic units. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-body connection and anti-collision device for floating structures. This invention provides options suitable for various shapes and connection methods, and the detachable design facilitates later recycling and maintenance. At the same time, considering the complexity of the movement of floating structures, it is also equipped with an expandable anti-collision device to meet the requirements of various sizes and connection methods, reduce structural damage caused by structural collisions, reduce the failure rate, and improve the operational stability of photovoltaic units.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A multi-body connection and anti-collision device for a floating structure, the floating structure being composed of several floating tubes, including a floating tube anti-collision device, a steel wire cable structure, and an end anti-collision device;

[0008] The floating pipe anti-collision device and steel wire cable structure are used when the floating pipes are connected side by side; the end anti-collision device is used when the floating pipes are connected through the ends of the floating pipes.

[0009] The floating tube anti-collision device includes a floating tube anti-collision pad and a metal fixing ring;

[0010] The floating tube anti-collision pad is made of elastic material and consists of a floating tube anti-collision ball, a floating tube anti-collision grid, a steel wire guide channel, and an anti-collision buffer layer.

[0011] The floating pipe anti-collision ball is integrally set on the surface of the floating pipe anti-collision pad and has a solid and / or hollow structure; the floating pipe anti-collision grid is arranged in the inner layer of the floating pipe anti-collision pad and directly contacts the floating pipe to increase friction and constrain the rotational displacement of the floating pipe anti-collision pad along the axial direction of the floating pipe; the steel wire guide groove is set on the floating pipe anti-collision pad to fix the steel wire cable; the anti-collision buffer layer is set in the middle of the floating pipe anti-collision pad;

[0012] The metal retaining ring is used for detachably connecting the floating pipe anti-collision pad and the floating pipe. The metal retaining ring is provided with a metal retaining groove and a steel wire guide hole. After the floating pipe anti-collision pad wraps around the floating pipe, it is fixed by two metal retaining rings and fastened by fasteners and metal retaining grooves. The steel wire guide hole is used for connecting steel wire ropes. The steel wire guide hole is chamfered around its perimeter to make the transition of the steel wire guide hole smooth and reduce wear on the steel wire ropes during operation.

[0013] The steel wire cable structure includes a steel wire cable rope, a steel wire cable pad, and a steel wire cable buckle. The steel wire cable pad is set in the steel wire conductor groove. The steel wire cable rope and the steel wire cable buckle connect two floating pipes covered with floating pipe anti-collision devices side by side.

[0014] The end anti-collision device includes an end anti-collision pad, an end anti-collision ball, and an end anti-collision guide wire hole. The end anti-collision ball is integrally set on the end anti-collision pad, and the end anti-collision guide wire holes are evenly distributed on the end anti-collision pad. A metal retaining ring wrapped around the end anti-collision pad is set in the end anti-collision guide wire hole. In use, the end anti-collision pad is fixed to the ends of two floating tubes that need to be connected, and the ends of the two floating tubes are detachably connected through the end anti-collision guide wire hole and the steel wire cable.

[0015] Furthermore, the steel wire ropes are selected according to different specifications based on the size of the float and the actual sea conditions; the steel wire rope padding layer is used to prevent wear and deformation of the floating pipe structure caused by tensile forces.

[0016] Furthermore, the end anti-collision pad includes two types. The first type is a hollow cylindrical structure with a base plate. The outer side of the base plate of the end anti-collision pad is provided with the end anti-collision ball. The inner wall of the hollow cylinder of the end anti-collision pad is integrally provided with an anti-collision grid to wrap the end of the float tube and increase friction to limit the axial rotation of the end anti-collision device. The other type is a circular structure that can be detachably installed at the end of the float tube by bolts.

[0017] Furthermore, both the floating tube anti-collision pad and the end anti-collision pad are made of rubber.

[0018] Furthermore, the end anti-collision ball adopts a solid and / or hollow structure to absorb the energy when the end of the floating tube is impacted; the end anti-collision ball is provided in several layers, and the end anti-collision balls in each layer are evenly arranged, with the number of end anti-collision balls in each layer from the center outward in a regular pattern of 3, 9, 15...

[0019] Furthermore, when the floats are connected through their ends, sealing plates are provided at both ends inside the floats.

[0020] Furthermore, the inner wall of the end of the float tube is provided with reinforcing ribs.

[0021] Compared with the prior art, the beneficial effects of the technical solution of the present invention are:

[0022] 1. This invention has the advantage of being detachable, allowing for recycling and reuse. It also enables the floating photovoltaic structure to be disassembled and inspected during operation and maintenance. The modular reinforcement of individual floating bodies is also convenient and does not affect the overall operational stability of the floating array. At the same time, the rich expandability of the structure makes large-scale operation of the floating photovoltaic structure possible.

[0023] 2. The anti-collision buffer layer of the present invention is arranged in the middle of each floating tube anti-collision pad. The elastic material can be easily set and adjusted with slots, so that when the anti-collision ball hits the anti-collision pad, the force will not be directly transmitted to the steel plate. The middle sandwich design plays a good role in buffering and absorbing energy.

[0024] 3. The anti-collision device and steel wire cable structure of the present invention improve the overall structural strength and stress stability. Only a few elbow plates are needed at the ends of the floating pipe to increase the tensile strength of the ends. The floating pipe is divided into compartments, and the steel wire cable structure can be directly installed on the outside of the bulkhead of each compartment. Utilizing the inherent strength of the floating body, the floating pipe structure does not require additional modifications to still meet the strength design requirements.

[0025] 4. The anti-collision ball, guide wire hole, steel wire cable, anti-collision buffer layer, and bolts of this invention can all be adjusted according to the actual size of the floating body and the sea conditions of the operating area. Accurate impact energy and tensile force extreme values ​​can be obtained through simulation calculations and experimental studies before installation. Setting anti-collision balls and steel wire cables with a certain safety margin can save construction costs while meeting requirements. Furthermore, due to its detachable nature, it can be reused and improved for other floating body structures.

[0026] 5. This invention allows for the installation of anti-collision devices both on shore and in dock, requiring only the pre-installation of connecting steel cables. Installation and connection can be quickly completed in designated operating areas, enabling large-scale expansion in a short time, significantly shortening the construction cycle and reducing the risks of offshore operations. During later maintenance, the flexible connection method makes construction operations more convenient, allowing each floating unit to be towed back for repair without affecting the normal power generation of other floating units. Simultaneously, faulty floating units can be directly replaced by a tugboat bringing a brand-new floating unit. After replacement, grid connection is restored, facilitating the upgrading and improvement of large-area floating structures.

[0027] 6. The dimensions of this invention can be modified to suit any floating structure employing similar floating tubes and pontoons, providing a new solution for the development of new marine energy sources. In the field of small floating bodies, it can provide solutions for floating photovoltaic structures and wave energy power generation devices; in the field of large floating bodies, it can provide solutions for offshore wind power and marine aquaculture. Furthermore, in an era of multi-energy complementarity, it can solve the connection and expansion between floating bodies of different sizes, ensuring operational stability.

[0028] 7. Although this invention is used for connection and collision avoidance between multiple floating bodies, when used alone, it can also protect itself when placed around the floating body, preventing collisions with ships and various marine organisms, providing operational safety for the floating body structure and reducing the failure rate.

Detailed Implementation

[0048] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0049] like Figures 1 to 17As shown, this embodiment provides a multi-body connection and anti-collision device for a floating structure. The floating structure consists of several floating tubes 4, including a floating tube anti-collision device 1, a steel wire cable structure 5, and an end anti-collision device 6. The floating tube anti-collision device 1 and the steel wire cable structure 5 are used when the floating tubes are connected side by side; the end anti-collision device 6 is used when each floating tube 4 is connected through a floating tube end 7. The floating tube anti-collision device 1 and the end anti-collision device 6 are all made of a combination of elastic (rubber) material and metal material, which can effectively restrain structural deformation while ensuring elastic energy absorption and improving the stability of the connection.

[0050] like Figures 1 to 3 As shown, the floating tube anti-collision device 1 includes a floating tube anti-collision pad 2 and a metal fixing ring 3; the metal fixing ring 3 is embedded in the floating tube anti-collision pad 2, and the floating tube anti-collision pad 2 covers any shape of floating tube 4 by wrapping and curling.

[0051] like Figures 4 to 6 As shown, under the constraint of the metal fixing ring 3, the floating pipe anti-collision pad 2 wraps around the floating pipe 4. The fixing bolt can connect the upper and lower parts of the metal fixing ring 3 through the metal fixing slot 3-1. The design of the metal fixing slot 3-1 allows the floating pipe anti-collision device 1 to be disassembled and reused.

[0052] In this embodiment, the floating tube anti-collision pad 2 is made of rubber material and consists of a floating tube anti-collision ball 2-1, a floating tube anti-collision grid 2-2, a steel wire guide channel 2-3, and an anti-collision buffer layer 2-4. The floating tube anti-collision ball 2-1 is integrally formed on the surface of the floating tube anti-collision pad 2 and is a solid and / or hollow structure. It can effectively buffer the impact vibration between two floating tubes 4, and its size and density can be adjusted according to the size and shape of the floating tubes 4.

[0053] The floating pipe anti-collision grille 2-2 is arranged in the inner layer of the floating pipe anti-collision pad 2 and is in direct contact with the floating pipe 4. Through the form of the pad, it can generate small deformation to absorb the impact energy again. It can also increase the roughness of the inner surface, so that the floating pipe anti-collision device 1 can limit the rotational displacement along the axial direction of the floating pipe 4 during the impact and pulling process.

[0054] The steel wire guide groove 2-3 is set on the upper and lower parts of the inner surface of the floating pipe anti-collision pad 2 to fix the steel wire cable 5-1;

[0055] The wire cable structure 5 includes a wire cable 5-1, a wire cable padding layer 5-2, and a wire cable clip 5-3. The wire cable 5-1 and the wire cable clip 5-3 connect two floating pipes 4, each covered with a floating pipe anti-collision device 1, side-by-side. The wire cable 5-1 can be arranged within the wire guide groove 2-3, along the entire axial direction of the floating pipe 4. An axial ring plate is added inside the floating pipe along the direction of the wire cable 5-1 arrangement, which effectively increases the upper limit of structural stress and strength. The wire cable 5-1 is pressed into the wire guide groove by the metal wire cable padding layer 5-2, preventing direct friction between the wire cable 5-1 and the floating pipe, thus preventing structural deformation and wear. Different types of wire cables 5-1 need to be selected according to the shape of different floating structures and the applicable sea areas, and the corresponding wire guide groove 2-3 and wire guide hole 3-2 can be adapted accordingly.

[0056] The metal retaining ring 3 is used for the detachable connection of the float anti-collision pad 2 and the float 4. The metal retaining ring 3 has a metal retaining groove 3-1 and a wire guide hole 3-2. The rectangular float anti-collision pad 2 wraps around the float 4 and is fixed by the butt joint of two metal retaining rings 3, and then secured with bolts and the metal retaining groove 3-1. The wire guide hole 3-2 is used for the connection of the wire cable 5-1, such as... Figure 15 The enlarged view shows that chamfers 3-3 are arranged on the wire guide holes 3-2. This can reduce the wear of the wire guide holes 3-2 on the wire cable 5-1 during the process of tension and displacement, and at the same time protect the wire cable 5-1 from breakage due to wear, thereby improving service life and ultimate tensile strength.

[0057] The anti-collision buffer layer 2-4 is located in the middle of the floating tube anti-collision pad 2.

[0058] The end anti-collision device includes an end anti-collision pad, an end anti-collision ball, and an end anti-collision wire hole. Preferably, the end anti-collision pad in this embodiment is designed in two types:

[0059] (1) As Figure 8 and Figure 10 As shown, the first type of end anti-collision pad 6 is a hollow cylindrical structure with a base plate. An end anti-collision ball 6-1 is provided on the outer side of the base plate. The end anti-collision ball 6-1 can be designed as a solid or hollow structure, circumferentially distributed along the axial direction, and its size and arrangement density can be changed as needed. End anti-collision guide holes 6-2 are evenly distributed at the bottom of the end anti-collision pad 6, allowing for more reasonable stress distribution on the end structure and improving load-bearing strength. Metal retaining rings are installed inside the end anti-collision guide holes 6-2 to prevent wear. An anti-collision grid 6-3 is integrally provided on the inner wall of the hollow cylinder of the end anti-collision pad 6, used to wrap the float end 7. Distributed longitudinally along the axial direction, it can improve rotational friction and limit the position of the end anti-collision device during rotation. The width and density of the grid can be changed according to the actual size and shape of the float end 7.

[0060] The metal plate at the end of the float pipe has through holes corresponding to the end anti-collision guide hole 6-2. The steel wire rope 5-1 is bent into a U-shape, and the U-shaped steel wire rope 5-1 passes sequentially through the through hole and the end anti-collision guide hole 6-2 of the metal plate at the end of the float pipe 7. It is then fixed to the U-shaped steel wire rope 5-1 extending from the end of the float pipe 7 on the opposite side by a steel wire rope clip 5-3. (See...) Figure 17 .

[0061] (2) Figure 11 and Figure 13 As shown, the second type of end anti-collision pad is a circular end anti-collision pad 8. This type is used because some floating pipes have other floating pipes or structures welded to their ends, forming a single unit at the end. Since the end anti-collision grille 6-3 cannot be installed, the circular end anti-collision pad 8 is fixed to the metal plate of the floating pipe end 7 by bolts 8-3. The outer surface of the circular end anti-collision pad 8 also has an integrally formed end anti-collision ball 8-1. The end anti-collision ball 8-1 can be a solid or hollow structure, circumferentially distributed along the axial direction, and its size and arrangement density can be changed as needed. End anti-collision guide wire holes 8-2 are evenly distributed on the circular end anti-collision pad 8.

[0062] Bolt 8-3 can connect the circular end anti-collision pad 8 and the float end 7 through the reserved circular end anti-collision guide hole 8-2 to fix the anti-collision device and prevent deformation and displacement. Different bolt 8-3 specifications are selected according to the size of the end anti-collision guide hole 8-2 and the installation requirements of the float.

[0063] The metal plate at the end of the float pipe has through holes corresponding to the end anti-collision guide hole 8-2. The steel wire rope 5-1 is bent into a U-shape, and the U-shaped steel wire rope 5-1 passes sequentially through the through hole and the end anti-collision guide hole 8-2 of the metal plate at the end of the float pipe 7. It is then fixed to the U-shaped steel wire rope 5-1 extending from the end of the float pipe 7 on the opposite side by a steel wire rope clip 5-3. (See...) Figure 17 .

[0064] Specifically, in this embodiment, an elbow plate is installed on the inner steel plate of the float pipe end 7 for reinforcement, which can prevent large deformation of the structure under tensile force. A waterproof seal can be installed at the connection point between the float pipe end 7 and the steel wire cable 5-1, which allows the end anti-collision device to be detachable without affecting the structural stability. Alternatively, after the float pipe ends of the two float pipes are joined, a sealing plate can be welded inside the float pipe end 7 to seal most of the interior of the float pipe.

[0065] In this embodiment, the end anti-collision balls are arranged in three layers, with each layer containing evenly distributed end anti-collision balls. The number of end anti-collision balls in each layer from the center outwards follows a pattern of 3, 9, and 15 respectively. When the ends of the two float tubes are joined, one of the float tubes can be rotated 60 degrees around its central axis so that the end anti-collision balls on the ends of the two float tubes can be staggered, allowing the ends of the two float tubes to fit more tightly together and making the two float tubes closer to a single unit.

[0066] like Figure 14 As shown, the floating tube anti-collision pad 2 has an anti-collision buffer layer 2-4 in the middle as a sandwich, which allows the floating tube anti-collision ball 2-1 to play a secondary energy absorption role when it hits the floating tube anti-collision pad 2. The end anti-collision pad 6 and the bolted circular end anti-collision pad 8 are both provided with anti-collision buffer layers 2-4 in the middle. The size and position of the buffer layers can be adjusted according to the collision energy calculated between the actual floating bodies.

[0067] like Figure 16 So and Figure 17 As shown, the steel wire cables 5-1 connecting different float structures can be bound using standard steel wire cable clips 5-3. After each steel wire cable 5-1 is wound, three steel wire cable clips 5-3 are typically installed as required. The steel wire cables between different floats are wound and cross-connected at their ends. For easy disassembly, the ends of the steel wire cables 5-1 can also be bound to standard safety buckles with nuts, facilitating the assembly and disassembly of multiple floats during installation and maintenance.

[0068] like Figure 18 As shown, the floating tube 4 and the floating tube end 7 are part of the floating photovoltaic structure. Due to different installation requirements, multi-body connections between floating tubes or between ends may be involved. The floating tube anti-collision device 1 and the end anti-collision device of this invention can well meet the above connection requirements. The end connection process involves the welding and assembly of the entire structure. The end can be exposed, and can be covered by the end anti-collision pad 6; or it can be connected to other components, requiring a circular end anti-collision pad 8. Different anti-collision devices can effectively adapt to the connection requirements of various floating photovoltaic structures, improving the safety and stability of the expansion.

[0069] This invention is not limited to the embodiments described above. The above description of specific embodiments is intended to illustrate and explain the technical solutions of this invention. The specific embodiments described above are merely illustrative and not restrictive. Without departing from the spirit and scope of the claims, those skilled in the art can make many specific modifications based on the teachings of this invention, and these modifications all fall within the scope of protection of this invention.
