Description

Technical Field

[0001] This invention relates to the field of marine photovoltaic concrete floating block connection structure technology, and particularly to a connection structure for marine photovoltaic concrete floating blocks. Background Technology

[0002] With the continuous growth of global energy demand and the ongoing research and development of clean energy technologies, offshore floating photovoltaic power stations have attracted widespread attention as an emerging way of utilizing renewable energy. Compared with land-based photovoltaic power stations, the layout of offshore floating photovoltaic power stations is quite different. All photovoltaic modules, inverters and other equipment in offshore floating photovoltaic power stations are arranged on floating structures, which are then connected to mooring and anchoring foundations to maintain their relatively fixed position in the sea.

[0003] In practical applications, the complex and ever-changing marine environment poses a severe challenge to floating photovoltaic power stations. In this process, concrete floats, as the core support structure that carries photovoltaic modules and provides buoyancy, are widely used due to their good economic performance. However, considering that the weight of the floats cannot be too large, designing the concrete floats into smaller floating units can achieve better wave-following performance. Therefore, the connection method between the concrete floats directly affects the working stability of the entire concrete floating photovoltaic power station at sea.

[0004] Currently, existing connection structures between floating bodies can be divided into three types: rigid, flexible, and integrated. While rigid structures can ensure the consistency and integrity of movement between floating bodies, they can also cause significant stress concentration at the structure, which can easily lead to damage to the components at that location. Flexible structures allow for relative movement of certain degrees of freedom between floating bodies, effectively reducing the load and structural stress between them. However, flexible structures alone cannot prevent direct collisions between floating bodies. Therefore, simple rigid or flexible connections cannot meet the connection requirements between concrete floating blocks. Integrated structures are suitable for aquatic environments where floating bodies only need to bear relatively small loads. However, the load-bearing capacity of these joints is limited. Furthermore, due to their integral molding characteristics, they are generally designed and manufactured using the same material as the floating body, which is not suitable for concrete floating blocks.

[0005] On the one hand, the concrete floats currently used for offshore floating photovoltaic systems are few and simple. On the other hand, the existing connection methods between concrete structures include prestressed connections, bolt / pin connections, modular tenon and mortise connections, hinge and ball joint connections, and intelligent adjustable hydraulic system connections. These connection methods have problems such as complex construction, high manufacturing precision requirements, high cost, and are not suitable for offshore concrete floats.

[0006] Therefore, this invention proposes a connection structure for marine photovoltaic concrete floating blocks to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a connection structure for marine photovoltaic concrete floats, which enables the floats to achieve better wave-following properties, prevents collisions between concrete floats, and reduces stress concentration in the connection structure between floats. At the same time, this connection structure needs to be easy to construct and install at sea, and be easier to operate in case of damage or maintenance, thus solving the problem that existing connection node forms are not suitable for connecting marine concrete floats.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a connection structure for marine photovoltaic concrete floats, comprising connection components applied to the concrete float unit; Each set of concrete floating block units includes an outer frame, and each set of outer frames houses and assembles multiple sets of floating blocks. Each set of connecting components includes a buffer rubber block embedded between two adjacent sets of concrete floating block units, with the buffer rubber block tightly attached to the floating block. A first connector is fixedly mounted on the top of the side of each set of outer frames away from the buffer rubber block, and a second connector is fixedly mounted on the top of the side of each set of outer frames close to the buffer rubber block. The second connector and the buffer rubber block are inserted into each other. The first connector on one set of outer frames and the second connector on the adjacent set of outer frames are fixedly connected by connecting bolts.

[0009] Preferably, each set of the outer frame is a precast concrete frame, and the two ends of the outer frame are integrally formed with connecting seats. The other end of the outer frame is open and integrally formed with a connecting frame. The buffer rubber block is engaged in the two sets of connecting frames and closely attached to the float, and is flush with the float.

[0010] Preferably, the end of the connecting seat is provided with a limiting groove that matches the buffer rubber block, the connecting frame is provided with a rectangular insertion hole, the buffer rubber block is provided with a rectangular channel corresponding to the rectangular insertion hole, and the inner sidewall of the outer frame is provided with a receiving groove that matches the float.

[0011] Preferably, the top of the connecting seat and the top of the connecting frame are pre-embedded with pre-cast fastening bolts that match the first connecting member and the second connecting member.

[0012] Preferably, the second connector includes a base plate located on top of the connecting frame, the base plate having screw holes matching the pre-embedded fastening bolts, a connecting column integrally formed in the middle of the top of the base plate, a supporting rib plate being provided between the connecting column and the base plate, and a transverse mounting hole being provided on the connecting column.

[0013] Preferably, the first connector has the same basic structure as the second connector, the direction of the mounting hole is the same as the length direction of the outer frame, and the connecting bolt passes through the mounting holes on the first connector and the second connector to connect the first connector and the second connector together.

[0014] Preferably, the second connector further includes a rectangular pin fixed to the center of the bottom of the base plate, based on the first connector. The rectangular pin matches the rectangular socket and the rectangular channel.

[0015] Preferably, the two side walls of the float are configured as pressure-bearing wedge surfaces, and each set of pressure-bearing wedge surfaces is provided with an arc-shaped groove, and a floating airbag is fixedly assembled in each set of arc-shaped grooves.

[0016] Preferably, the cross-sectional dimensions of the buffer rubber block match the limiting groove, the depth of the limiting groove is greater than the length of the buffer rubber block extending into the limiting groove, the rectangular channel is set as a buffer groove, and the length of the buffer groove is three times the width of the rectangular pin cross-section.

[0017] Preferably, a buffer airbag is fixed on the side of each set of limiting grooves away from the opening, and the buffer airbag is connected to each set of floating airbags through an air supply pipe.

[0018] The technical effects and advantages of this invention are as follows: 1. This invention utilizes connecting components to quickly connect concrete floating block units, exhibiting good elasticity and fatigue resistance. When combined with the concrete floating block units, it extends the service life of the connection nodes while reducing the risk of damage caused by cyclic loads. It allows for a certain degree of relative rotation between the concrete floating block units, providing a buffering effect when subjected to external forces, thus preventing component breakage or fracture due to excessive rigidity. Simultaneously, it ensures overall structural stability. The construction and installation are relatively simple, and in the event of damage, the connecting component structure can be directly replaced and repaired individually without requiring work on the floating body structure.

[0019] 2. This invention incorporates floating airbags on the floats. The use of the floats in conjunction with the floating airbags, under the guiding effect of the wedge-shaped surface, causes seawater to impact adjacent sets of floats. This utilizes the impact force of the waves to force the two sets of floats to move away from each other, increasing the distance between adjacent sets of floats. This reduces the impact of the waves on the floats and guides the flow of the impacting waves, preventing excessive impact on the concrete float units. It not only buffers the impact of the waves but also utilizes the impact of the waves on the pressure-bearing wedge-shaped surface to provide an upward driving force for the concrete float units, preventing them from being submerged in seawater and facilitating their floating on the sea surface.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] First embodiment: like Figures 1 to 9 As shown, this embodiment discloses a connection structure for marine photovoltaic concrete floats, including a connection component 20 applied to the concrete float unit 10. The connection component 20 can quickly connect two adjacent sets of concrete float units 10, improving the connection convenience.

[0024] Please see Figures 2-8 Each concrete float unit 10 includes an outer frame 11, and each outer frame 11 houses and assembles multiple floats 12. The multiple floats 12 are engaged within the outer frame 11, which can increase the buoyancy of the outer frame 11.

[0025] Please see Figures 1-8 Each set of connecting components 20 includes a buffer rubber block 21 embedded between two adjacent sets of concrete floating block units 10, and the buffer rubber block 21 is in close contact with the floating block 12. A first connector 14 is fixedly installed on the side of the top of each set of outer frames 11 away from the buffer rubber block 21, and a second connector 22 is fixedly installed on the side of the top of each set of outer frames 11 close to the buffer rubber block 21. The second connector 22 and the buffer rubber block 21 are inserted and assembled. The first connector 14 on one set of outer frames 11 and the second connector 22 on the adjacent set of outer frames 11 are fixedly connected by connecting bolts 23.

[0026] Specifically, after the floats 12 are sequentially installed inside the outer frame 11, the buffer rubber blocks 21 are placed close to the floats 12 to separate the two adjacent sets of outer frames 11. Then, the second connector 22 is assembled on the outer frame 11, which simultaneously limits the installation of the buffer rubber blocks 21. Since the first connector 14 is assembled on the outer frame 11 and corresponds to the pre-embedded fastening bolt 13, the first connector 14 can be fixedly assembled on the top of the outer frame 11 by installing nuts on the pre-embedded fastening bolt 13. Then, the first connector 14 and the second connector 22 are fixedly connected by connecting bolts 23, thereby completing the connection between the two adjacent sets of concrete float units 10. The buffer rubber blocks 21 can prevent the impact between the two adjacent sets of concrete float units 10 and allow the two adjacent sets of concrete float units 10 to move to a certain extent. When the concrete float unit 10 is subjected to external force, it can play a certain buffering role, thereby avoiding the problem of component cracking or breakage caused by excessive rigidity of the concrete float unit 10.

[0027] It should be noted that you should refer to [link / reference]. Figure 3 Each set of outer frames 11 is a precast concrete frame. Connecting seats 111 are integrally formed on both ends of the outer frame 11. Each connecting seat 111 has a limiting groove 112 at its end that matches the buffer rubber block 21. The other end of the outer frame 11 is open and has an integrally formed connecting frame 114. A rectangular insertion hole 115 is provided on the connecting frame 114. A rectangular channel corresponding to the rectangular insertion hole 115 is provided on the buffer rubber block 21. A container matching the float 12 is provided on the inner sidewall of the outer frame 11. The buffer rubber block 21 is engaged inside the limiting groove 112 in the trough 113. The buffer rubber block 21 is engaged in the two sets of connecting frames 114 and is close to the float 12 and flush with the float 12. The connecting frames 114 and the rectangular insertion hole 115 complete the limiting of the buffer rubber block 21. Moreover, the buffer rubber block 21 is close to the float 12, which ensures the compactness between the structures and prevents the buffer rubber block 21 from loosening between the two adjacent sets of outer frames 11, ensuring that the two adjacent sets of outer frames 11 have good anti-collision capability.

[0028] Please see Figure 3 and Figure 5 Both the top of the connecting seat 111 and the top of the connecting frame 114 are pre-embedded with fastening bolts 13 that match the first connecting piece 14 and the second connecting piece 22, which facilitates the rapid installation of the first connecting piece 14 and the second connecting piece 22.

[0029] Please see Figure 8 and Figure 9 The second connector 22 includes a base plate 221 located on top of the connecting frame 114. The base plate 221 has screw holes 224 that match the pre-embedded fastening bolts 13. A connecting post 222 is integrally formed in the middle of the top of the base plate 221. A supporting rib 223 is provided between the connecting post 222 and the base plate 221. A transverse mounting hole 225 is provided on the connecting post 222. The base plate 221 corresponds to the pre-embedded fastening bolts 13 through the screw holes 224, which facilitates the quick positioning of the second connector 22. Then, nuts are installed on the pre-embedded fastening bolts 13 to fix the second connector 22.

[0030] Please see Figures 6-9The basic structure of the first connector 14 is the same as that of the second connector 22. The second connector 22, based on the first connector 14, also includes a rectangular pin 226 fixed in the middle of the bottom of the base plate 221. The direction of the mounting hole 225 is the same as the length direction of the outer frame 11. The connecting bolt 23 passes through the mounting hole 225 on the first connector 14 and the second connector 22 to connect the first connector 14 and the second connector 22 together, improving the ease of installation between the structures. The rectangular pin 226 matches the rectangular insertion hole 115 and the rectangular channel. After the rectangular pin 226 passes through the rectangular insertion hole 115 and the rectangular channel, it can realize the limiting installation between the second connector 22 and the connecting frame 114 and the buffer rubber block 21. After installing the nut on the pre-embedded fastening bolt 13, the second connector 22 is fixed, improving the connection safety.

[0031] It should be noted that the outer frame 11 is pre-processed and pre-embedded fastening bolts 13 are prepared during the pouring process. After the concrete outer frame 11 hardens, holes for inserting rectangular pins 226 are opened on the connecting frame 114, and limiting grooves 112 suitable for buffer rubber blocks 21 are opened on the connecting seat 111. When the second connecting piece 22 is welded, bolt holes 224 matching the pre-embedded fastening bolts 13 are opened on the bottom plate 221. The connecting column 222 is first welded on top, and then the supporting rib plate 223 is welded through the connecting column 222, so that the center line of the supporting rib plate 223 is aligned with the center line of the connecting column 222. At the same time, elastic washers and anti-loosening nuts are installed on the pre-embedded fastening bolts 13 to fix the first connecting piece 14 and the second connecting frame 22.

[0032] A rectangular channel for fixing the rectangular pin 226 is opened at a predetermined position on the buffer rubber block 21. Then, the foam material floats 12 are placed into the outer frame 11 in sequence. The buffer rubber block 21 is placed close to the floats 12, and the rectangular channel of the buffer rubber block 21 is aligned with the rectangular through hole 115 on the outer frame 11. The first connector 14 and the second connector 22 can then be installed on the outer frame 11. The first connector 14 and the second connector 22 on adjacent outer frames 11 are then connected by connecting bolts 23, thereby completing the installation between adjacent concrete float units 10.

[0033] The outer frame 11 is made of C40 anti-corrosion concrete, the internal foam material float 12 is made of EPS material, the buffer rubber block 21 and elastic pad are made of high elasticity rubber material, the pre-embedded fastening bolt 13 is made of carbon steel material, and the first connecting piece 14 and the second connecting piece 22 are both made of Q355 steel material. The anti-loosening nut used is made of carbon steel material.

[0034] Second embodiment: like Figures 5-14As shown, this embodiment provides a connection structure for offshore photovoltaic concrete floating blocks, including the structure in the first embodiment. Please also refer to... Figure 13 and Figure 14 The two side walls of the float 12 are configured as pressure-bearing wedge surfaces 121. Each set of pressure-bearing wedge surfaces 121 is provided with an arc-shaped groove 122. A floating airbag 123 is fixedly installed in each set of arc-shaped grooves 122. After the floating airbag 123 is inflated, it can provide buoyancy for the outer frame 11 after it floats at sea. At the same time, the buoyancy provided by the float 12 itself to the outer frame 11 is superimposed, which is more conducive to the concrete float unit 10 floating on the sea surface. Moreover, when the concrete float unit 10 is impacted by waves, the waves can impact the pressure-bearing wedge surfaces 121. Under the guiding effect of the wedge surfaces, the seawater impacts the adjacent two sets of wedge surfaces. The impact between the floats 12 allows the impact force of the waves to force the two sets of floats 12 to move away from each other, thereby increasing the distance between the two sets of floats 12 and reducing the impact of the waves on the floats 12. This also helps to guide the waves during the impact, preventing the waves from having too much impact on the concrete float unit 10. In addition to buffering the impact force of the waves, the impact of the waves on the pressure wedge surface 121 can also provide an upward driving force for the concrete float unit 10, preventing the concrete float unit 10 from being submerged in seawater and making it easier for the concrete float unit 10 to float on the sea surface.

[0035] It is worth noting that, please refer to Figures 10-13 The cross-sectional dimensions of the buffer rubber block 21 match those of the limiting groove 112, ensuring that the buffer rubber block 21 is engaged inside the limiting groove 112 and preventing the buffer rubber block 21 from swinging back and forth.

[0036] Please see Figure 10 and Figure 13 The depth of the limiting groove 112 is greater than the length of the buffer rubber block 21 extending into the limiting groove 112, which can provide the movement margin of the buffer rubber block 21 when it moves inside the limiting groove 112. Moreover, the rectangular channel on the buffer rubber block 21 is set as a buffer groove 25, and the length of the buffer groove 25 is three times the width of the rectangular pin 226. Thus, when the float 12 moves inside the outer frame 11, it can squeeze the buffer rubber block 21 through the float 12, so that the buffer rubber block 21 can move inside the outer frame 11 under the action of the buffer groove 25, avoiding the second connector 22 limiting the buffer rubber block 21 and preventing it from moving. A buffer airbag 24 is fixed on the side away from the opening in each set of limiting grooves 112. The buffer airbag 24 is connected to each set of floating airbags 123 through an air supply pipe.

[0037] In actual use, when the buffer airbag 24 expands, it can exert a compressive force on the buffer rubber block 21, thereby making the buffer rubber block 21 tightly adhere to the float 12, ensuring the compactness of the float 12 installed inside the outer frame 11. When the waves impact the pressure-bearing wedge surface 121 on the float 12, the impact force is divided into horizontal and vertical impact forces on the float 12. The vertical impact force drives the concrete float unit 10 to move upward and float out of the water, while the horizontal component forces the float 12 to compress the adjacent float 12, which in turn compresses the buffer rubber block 21 and then the buffer airbag 24. The compression of the buffer airbag 24 achieves the buffering of the concrete float unit 10 against the waves. At the same time, after the waves impact the float 12, it can provide the rebound force for the float 12 to reset.

[0038] It should be noted that when the waves impact the pressure-bearing wedge surface 121, the floating airbag 123 will also be impacted by the waves, causing the floating airbag 123 to be compressed. This causes the gas in the floating airbag 123 to be introduced into the buffer airbag 24 through the gas supply pipe, thereby increasing the compressive strength of the buffer airbag 24 and thus increasing the impact resistance of the buffer airbag 24 when facing the impact of the waves. After the concrete float unit 10 is impacted by the waves, the buffer airbag 24 uses its own elastic force after being compressed to drive the buffer rubber block 21 to reset and move within the outer frame 11, thereby causing the float 12 to reset. Moreover, the gas inside the buffer airbag 24 flows back into the floating airbag 123 through the gas supply pipe, so that the floating airbag 123 can once again provide buoyancy to the concrete float unit 10.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
