Description

Technical Field

[0001] The utility model relates to the technical field of offshore photovoltaics, in particular to a floating body connection device and an on-water floating photovoltaic power generation system. Background Art

[0002] One of the mainstream implementation strategies of current waterborne photovoltaic power generation technology is to cleverly install efficient photovoltaic modules on specially designed floats, which are well designed to ensure that photovoltaic panels can float stably and safely on the surface of vast waters. The floats are not isolated, but closely connected through a carefully planned fixed connection system to form a stable overall structure to resist slight displacement caused by water fluctuations and ensure the stable operation of the photovoltaic power generation system.

[0003] In this connection system, the buoys are usually fixed with high-strength rigid connectors, such as metal bolts, steel connecting plates or specially made composite structural parts, which are strictly selected to meet the requirements of long-term underwater environment and wind and wave impact. However, although these rigid connectors can provide reliable connection strength in the early stage, their weaknesses gradually become apparent in the face of complex and changeable wind and wave conditions for a long time.

[0004] First, due to the continuous and periodic impact of wind and waves, rigid connectors are constantly subjected to composite stresses such as tension, compression and torsion, which can easily lead to changes in the microstructure inside the material, thereby causing fatigue. Over time, this fatigue accumulation will gradually weaken the bearing capacity of the connector until it eventually breaks or fails, affecting the stability and safety of the entire photovoltaic power generation system.

[0005] Secondly, rigid connectors are often designed without sufficient buffering mechanisms to cope with sudden strong winds and waves. Under extreme weather conditions, huge impact forces may directly act on the connection points, causing instantaneous overload and accelerating damage to the connectors. This inability to effectively buffer impact forces not only increases maintenance costs, but may also cause potential damage to the photovoltaic modules themselves. Utility Model Content

[0006] In view of this, the purpose of the present invention is to overcome the deficiencies in the related art. The present invention provides a floating body connecting device.

[0007] The utility model provides the following technical solutions:

[0008] A floating body connecting device is used to connect adjacent floating bodies in a floating photovoltaic power generation system on water. The floating body connecting device comprises a connecting assembly, a chain and a buffer sleeve.

Specifically, the buffer sleeve as a whole is a spherical elastic member.

[0010] As a further improvement of the above technical solution, the buckles at both ends of the chain are respectively fixedly embedded in the corresponding first connecting member and the second connecting member.

[0011] As a further improvement of the above technical solution, the first connecting member and the second connecting member are both in the shape of a platform, the top surfaces of the first connecting member and the second connecting member are arranged opposite to each other, the buckles at both ends of the chain are respectively fixedly connected to the corresponding top surfaces, and the floating body is provided with a card slot corresponding to the first connecting member and the second connecting member, and the ends of the first connecting member and the second connecting member facing away from the chain are respectively carded in the corresponding card slots.

[0012] As a further improvement of the above technical solution, the first connecting member and the second connecting member are both integrally formed.

[0013] As a further improvement of the above technical solution, a limiting rod is respectively provided in the first connecting member and the second connecting member, the buckle sleeve at the end of the chain is arranged on the limiting rod, and the axis of the limiting rod is perpendicular to the extension direction of the chain.

[0014] As a further improvement of the above technical solution, the first connecting member and the second connecting member are made of concrete.

[0015] As a further improvement of the above technical solution, each of the buckles of the chain is made of manganese steel, specifically galvanized G80 grade national standard manganese steel.

[0016] As a further improvement of the above technical solution, the width of the buffer sleeve covering the ring buckle is A, the width of a single ring buckle is B, and the values ​​of A and B satisfy: 2B≤A≤3B.

[0017] As a further improvement of the above technical solution, the splicing length of the plurality of buffer sleeves is smaller than the length of the chain.

[0018] As a further improvement of the above technical solution, the relative movable distance between the buffer sleeve closest to the first connecting member and the second connecting member and the corresponding first connecting member and the second connecting member ranges from 0.5A to A.

[0019] As a further improvement of the above technical solution, the buffer sleeve is made of polyurethane.

[0020] The utility model also provides a floating photovoltaic power generation system on water, comprising a float, a photovoltaic module and a float connection device as described in any one of the above, wherein the photovoltaic module is arranged on the float, and adjacent floats are connected by the float connection device.

[0021] Compared with the related art, the beneficial effects of the utility model are:

[0022] The utility model designs an innovative floating body connection device, which aims to improve the overall stability and safety performance of the floating photovoltaic power generation system on the water. During the installation phase, the operation process is simple and efficient: First, the technicians need to firmly connect the carefully designed first connector and the second connector to their respective corresponding floating bodies, which are equipped with high-efficiency photovoltaic modules to maximize the solar energy collection efficiency. Then, select an appropriate number of buffer sleeves and accurately put them on the pre-selected chains one by one. This step is crucial for the subsequent shock absorption effect. Finally, through precise fixing means, the two ends of the chain are tightly connected to the previously installed first connector and the second connector. At this point, the installation of the entire connection device is successfully completed.

[0023] In actual use, the floating body connection device has shown excellent performance advantages. In particular, the chain, as the core component connecting two adjacent floating bodies, is designed to allow slight relative movement between adjacent floating bodies under the influence of natural environmental factors such as wind and waves. This feature enables the chain to flexibly respond to and absorb the energy brought by external impact, effectively reducing the composite stress caused by direct force, thereby extending the service life of the chain and the entire connection system.

[0024] What is even more ingenious is that the buffer sleeve carefully arranged on the outside of the chain has a unique curved convex surface design that is not only beautiful but also practical. When water flow or wind and waves hit the chain, these convex surfaces can serve as the first line of defense, effectively guiding and dispersing the impact force of the water flow, so that the impact force that may have been concentrated on the chain can be dispersed, greatly reducing the direct burden on the chain. This innovative design not only enhances the impact resistance of the chain, but also further improves the stability and safety of the entire floating photovoltaic power generation system in the face of severe weather conditions, ensuring that the system can continuously and stably output electrical energy, providing a solid guarantee for the application of clean energy.

[0036] Example 1

[0037] Combination Figure 1 , Figure 2 As shown, this embodiment provides a floating body connection device for connecting adjacent floating bodies in a water floating photovoltaic power generation system. The floating body connection device includes a connection assembly 300, a chain 100, and a buffer sleeve 200.

[0038] The connecting assembly 300 includes a first connecting member 310 and a second connecting member 320 which are arranged opposite to each other; the first connecting member 310 and the second connecting member 320 are both used to connect a floating body with a photovoltaic component; the chain 100 is connected by a plurality of buckles 110 which are sequentially fastened together, and the two ends of the chain 100 are respectively fixedly connected to the corresponding first connecting member 310 and the second connecting member 320; the buffer sleeve 200 is sleeved on the chain 100, and the buffer sleeve 200 is provided with a plurality of them, and the side surface of the buffer sleeve 200 is an arc-shaped convex surface 210. Specifically, the buffer sleeve 200 is a spherical elastic member as a whole.

[0039] The floating body connection device provided in this embodiment is intended to improve the overall stability and safety performance of the floating photovoltaic power generation system on the water. During the installation stage, first, the first connector 310 and the second connector 320 are firmly connected to their respective corresponding floating bodies, which are provided with photovoltaic modules for photovoltaic power generation. Subsequently, an appropriate number of buffer sleeves 200 are selected and installed one by one on the pre-selected chain 100. Finally, the two ends of the chain 100 are tightly connected to the previously installed first connector 310 and the second connector 320. At this point, the installation of the entire floating body connection device is successfully completed, and the installation process is simple and quick.

[0040] In actual use, by using the chain 100 as the core component connecting two adjacent floating bodies, its design allows slight relative movement between adjacent floating bodies under the influence of natural environmental factors such as wind and waves. This feature enables the chain 100 to flexibly respond to and absorb the energy brought by external impact, effectively reducing the composite stress caused by direct force, thereby extending the service life of the chain 100 and the entire connection system.

[0041] Furthermore, the buffer sleeve 200 carefully arranged outside the chain 100 has a unique arc-shaped convex surface 210 design that is not only beautiful, but also practical. When water flow or wind and waves hit the chain 100, these convex surfaces can serve as the first line of defense, effectively guiding and dispersing the impact force of the water flow, so that the impact force that may have been concentrated on the chain 100 can be dispersed, greatly reducing the direct burden of the chain 100. The above-mentioned setting method not only enhances the impact resistance of the chain 100, but also further improves the stability and safety of the entire floating photovoltaic power generation system in the face of severe weather conditions, ensuring that the system can continuously and stably output electrical energy, and providing a solid guarantee for the application of clean energy.

[0042] In some embodiments, the buckles 110 at both ends of the chain 100 are respectively fixed and embedded in the corresponding first connector 310 and the second connector 320. Through the preset connection between the chain 100 and the first connector 310 and the second connector 320, the connection reliability between the chain 100 and the first connector 310 and the second connector 320 can be effectively ensured.

[0043] In some embodiments, the first connector 310 and the second connector 320 are both in a platform shape, and the top surfaces 311 of the first connector 310 and the second connector 320 are arranged opposite to each other. The buckles 110 at both ends of the chain 100 are fixedly connected to the corresponding top surfaces 311 respectively. By setting the first connector 310 and the second connector 320 in a platform shape, it is convenient to make the center of gravity of the first connector 310 and the second connector 320 biased toward the corresponding floating body, effectively reducing the impact of the chain 100 on the floating body when shaking, thereby ensuring the normal operation of the photovoltaic components on the floating body; the floating body is provided with a card slot corresponding to the first connector 310 and the second connector 320, and the ends of the first connector 310 and the second connector 320 away from the chain 100 are respectively snapped into the corresponding card slots, and the first connector 310 and the second connector 320 are connected to the corresponding floating body by snapping, which is convenient for disassembly and assembly, and is convenient for subsequent maintenance and replacement, and is convenient for improving work efficiency.

[0044] In some embodiments, the first connecting member 310 and the second connecting member 320 are both integrally formed to ensure the structural strength of the first connecting member 310 and the second connecting member 320 .

[0045] In some embodiments, a limiting rod 312 is respectively provided in the first connecting member 310 and the second connecting member 320, and the buckle 110 at the end of the chain 100 is sleeved on the limiting rod 312, and the axis of the limiting rod 312 is perpendicular to the extension direction of the chain 100; by limiting the limiting rod 312 in the first connecting member 310 and the second connecting member 320, it is convenient to limit the position of the buckle 110 at the end of the chain 100 in the corresponding first connecting member 310 and the second connecting member 320, thereby preventing the buckle 110 at the end of the chain 100 from detaching from the corresponding first connecting member 310 and the second connecting member 320, thereby improving the reliability of the use of this embodiment.

[0046] In some embodiments, the first connector 310 and the second connector 320 are made of concrete, so that the first connector 310 and the second connector 320 have excellent durability and mechanical properties while reducing the difficulty of production and processing, and are easy to process into specific shapes as needed to adapt to more usage scenarios; of course, in other embodiments of the utility model, the first connector 310 and the second connector 320 can also be made of other materials.

[0047] In some embodiments, each link 110 of the chain 100 is made of high-quality manganese steel, which is a metal material with high strength, high wear resistance and good toughness. Specifically, we selected galvanized G80-grade national standard manganese steel, which not only inherits the excellent properties of manganese steel itself, but also further enhances its corrosion resistance through galvanizing, effectively extending the service life of the chain 100. The galvanized layer acts as a protective barrier, which can effectively isolate the chain 100 from contact with corrosion factors such as moisture and salt in the external environment, thereby maintaining the cleanliness and strength of the chain 100. At the same time, the G80-grade standard also ensures that the chain 100 can still maintain stable performance when subjected to heavy loads, meeting the use requirements under various harsh working conditions.

[0048] In some embodiments, the sleeve width of the buffer sleeve 200 for the ring buckle 110 is A, the width of a single ring buckle 110 is B, and the values ​​of A and B satisfy: 2B≤A≤3B; by limiting the sleeve width of the buffer sleeve 200 for the ring buckle 110 and the width of the ring buckle 110 to the above-mentioned relationship, when each of the ring buckles 110 moves relative to each other, the buffer sleeve 200 can always cover the connection between two adjacent ring buckles 110, so as to reduce the impact on this position, thereby further ensuring the reliability of use of this embodiment.

[0049] In some embodiments, the splicing length of the plurality of buffer sleeves 200 is smaller than the length of the chain 100; when the respective buckles 110 move relative to each other, the adjacent buffer sleeves 200 can also move relative to each other, thereby facilitating the mitigation of the water flow impact on the arc-shaped convex surface 210 of the buffer sleeve 200, thereby improving the impact resistance of the present embodiment.

[0050] In some embodiments, the relative movable distance range between the buffer sleeve 200 closest to the first connector 310 and the second connector 320 and the corresponding first connector 310 and the second connector 320 is 0.5A to A, so as to avoid the buffer sleeve 200 from providing insufficient protection to the buckle 110 due to the excessive relative position, and ensure that the buffer sleeve 200 can provide stable and reliable buffering and protection for each buckle 110.

[0051] In some embodiments, the cushion sleeve 200 is made of polyurethane. As an excellent elastomeric material, polyurethane has excellent wear resistance, tear resistance and good resilience, which enables it to exhibit excellent performance when used as a cushioning element. This material can not only effectively absorb and disperse impact force, reduce direct contact and wear between mechanical parts, but also quickly return to its original shape after being subjected to pressure, maintaining long-term stability and durability.
