Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and specifically to a honeycomb-shaped floating marine CFRP cable-supported photovoltaic support system. Background Technology

[0002] Solar panels are the core component of a photovoltaic power generation system. They can absorb sunlight and convert solar radiation directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. Compared with land, the ocean has a large area of ​​sea surface, which is an excellent site for building photovoltaic power plants. It can effectively alleviate the site limitations of laying solar power panels on land and bring a continuous source of offshore power to coastal areas and even inland areas.

[0003] Existing surface photovoltaic (PV) support systems generally employ floating and fixed methods. Fixed PV systems are more difficult to construct and more expensive, making them unsuitable for nearshore environments. Floating PV systems are easier to construct and less expensive, and are easier to deploy and promote. However, the harsh wind and wave conditions at sea mean that existing floating systems are mostly circular, single-layer connected structures, which cannot allow multiple PV supports to be spliced ​​together to work collaboratively, thus compromising the stability of the PV support system on the sea surface.

[0004] Therefore, improving the stability of floating photovoltaic support system structures is a problem that needs to be solved in this field. Summary of the Invention

[0005] To address the technical problem of low reliability in existing floating photovoltaic support systems, the present invention aims to provide a honeycomb-shaped floating marine CFRP cable-supported photovoltaic support system, which can keep the solar panels in a horizontal and stable state while floating, effectively overcoming the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides a honeycomb-shaped floating marine CFRP cable-supported photovoltaic support system. Several honeycomb-shaped floating marine CFRP cable-supported photovoltaic support systems can be spliced ​​together to form a honeycomb structure collaborative system, including CFRP cable units, load-bearing units, floating tube units, and hexagonal beam units. The floating tube units are set at the bottom of the hexagonal beam units to form the floating body of the hexagonal beam units. The CFRP cable units include first CFRP cables and third CFRP cables. The first CFRP cables connect the load-bearing units to the hexagonal beam units at each node corresponding to the first CFRP cables. The third CFRP cables are distributed between adjacent first CFRP cables and their two ends are connected to the adjacent first CFRP cables to form a transverse cable net system. The photovoltaic units are laid on the transverse cable net system to form a honeycomb structure.

[0007] Furthermore, the floating tube unit includes an air-filling area and a water-filling area, with the water-filling area located at the bottom of the air-filling area, and the two connected to form an integrated structure.

[0008] Furthermore, the hexagonal beam unit includes a hexagonal beam and a third connecting component. A third mounting groove is provided at each corner of the hexagonal beam unit. The third connecting component is disposed in the third mounting groove. A CFRP cable unit is disposed on the third connecting component and connected to the force-bearing unit.

[0009] Furthermore, the force-bearing unit is located at the center of the hexagonal beam unit. The force-bearing unit includes a first force-bearing disk, a central column, and a second force-bearing disk. The first and second force-bearing disks are respectively arranged at both ends of the central column to form a symmetrical structure. A plurality of first and second connecting components for setting CFRP cable units are respectively distributed on the first and second force-bearing disks. CFRP cable units are respectively set on the first and second connecting components and connected to the third connecting component on the beam unit to form a cable net structure.

[0010] Furthermore, the first force-bearing disc has several first mounting grooves along its circumference, and the first connecting components are installed in the first mounting grooves.

[0011] Furthermore, the second force-bearing disk has several second mounting slots along its circumference corresponding to the first force-bearing disk, and the second connecting components are installed in the second mounting slots.

[0012] Furthermore, a first CFRP cable is provided between the first connecting component and the third connecting component.

[0013] Furthermore, the CFRP cable unit also includes a second CFRP cable, the two ends of which are connected to a second connecting component and a third connecting component, respectively. The second CFRP cable and the first CFRP cable form a cooperative force-bearing system by setting CFRP support cables, which jointly bear the vertical load fixed force-bearing unit.

[0014] The honeycomb-shaped floating marine CFRP cable-supported photovoltaic support system provided by this invention has a honeycomb system form that facilitates the formation of a collaborative system of multiple photovoltaic support systems, which improves its resistance to wave impact in the marine environment. The large-scale collaborative system also facilitates the management and maintenance of photovoltaic support systems.

[0015] Meanwhile, the honeycomb system employs a symmetrical cable connection structure, which ensures the system's stability on the sea surface.

[0016] Secondly, the honeycomb system uses CFRP cables and CFRP components as the main load-bearing components, which can effectively solve the corrosion problem in marine environments. Attached Figure Description

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0029] Existing floating photovoltaic support systems are mostly circular structures. These circular structures cannot work together in a coordinated manner to ensure stability on the sea surface. To address this, this solution provides a honeycomb-shaped floating marine CFRP cable-supported photovoltaic support system. The honeycomb structure is a polygonal symmetrical structure, which facilitates the formation of a coordinated system by multiple photovoltaic support systems, thereby improving its resistance to wave impact in the marine environment.

[0030] The honeycomb-shaped floating offshore CFRP cable-supported photovoltaic system provided in this solution is described in [reference needed]. Figure 1 It can form a honeycomb structure by splicing multiple honeycomb floating marine CFRP cable-supported photovoltaic support systems, which can cooperate to improve its stability in the marine environment and effectively resist the problem of wave impact.

[0031] See Figure 2 The honeycomb-shaped floating marine CFRP cable-supported photovoltaic support system includes cable unit 100, force-bearing unit 200, floating tube unit 300, hexagonal beam unit 400, and photovoltaic unit 500.

[0032] The floating tube unit 300 is connected to the hexagonal beam unit 400, which allows the hexagonal beam unit 400 to float on the sea surface. The force-bearing unit 200 is located at the center of the hexagonal beam unit 400 and is connected to the hexagonal beam unit 400 through the cable unit 100 to form a honeycomb-like cable net structure. The photovoltaic unit is then laid on the cable net structure to form the honeycomb-like floating marine CFRP cable-supported photovoltaic support system provided in this solution.

[0033] Specifically, the floating tube unit 300 is positioned at the bottom of the edge of the hexagonal beam unit 400, corresponding to the structure of the hexagonal beam unit 400, forming a floating body of the hexagonal beam unit 400. The floating tube unit 300 can drive the hexagonal beam unit 400 to float stably on the sea surface.

[0034] See Figure 3 The hexagonal floating tube unit 300 includes an air-filled area 320 and a water-filled area 310. The water-filled area 310 is located at the bottom of the air-filled area 320, and the two are connected to form an integrated structure. The water-filled area 310 is placed in seawater, and the air-filled area 320 floats on the sea level.

[0035] The top of the inflation zone 320 is connected to the hexagonal beam unit 400. An inflation port is provided on the inflation zone 310. The inflation zone 320 is inflated through the inflation port, so that the beam unit 400 floats on the sea level.

[0036] The water filling area 310 is equipped with a water filling port, through which water is filled into the interior of the water filling area 310.

[0037] The air-filling zone 320 of the float tube has a rectangular cross section, and the water-filling zone 310 is divided into an upper part 311 and a lower part 312. The lower part 312 has a semi-elliptical structure, and the upper part 311 is a transitional arc cross section between the rectangular cross section of the air-filling zone 320 and the semi-elliptical cross section of the lower part 312 of the water-filling zone.

[0038] The major axis of the elliptical transition arc section is the same as the length of the rectangular section of the air-filling zone 320, and the minor axis is half the length of the major axis. The minor axis of the semi-elliptical section of the lower part 312 of the water-filling zone is half the length of the major axis of the elliptical transition arc section, and the major axis is twice the length of its own minor axis. This design ensures that the water-filling zone of the floating tube unit 300 has sufficient vertical length while maintaining a smooth, full, and slender surface curvature. The smooth elliptical surface of the floating tube unit 300 reduces seawater resistance when the photovoltaic support system is towed and floats in the ocean. After the water-filling zone 310 is vertically filled, the vertical mass is concentrated in the lower part of the water-filling zone 310, which also lowers the center of gravity of the floating tube unit 300, thus maintaining the stability of the floating tube unit 300 and the entire system as much as possible in complex and wavery marine environments.

[0039] In this design, the air-filling area 320 and water-filling area 310 of the floating tube unit 300 are preferably made of regular shapes such as rectangular cross-section and elliptical cross-section, which can reduce the complexity of the manufacturing process of the floating tube structure and improve production efficiency.

[0040] The top of the water-filling area 310 is a large-diameter connecting end, which is used to connect to the bottom of the air-filling area 320. The bottom is a small-diameter cylinder. By filling the small-diameter end with water, the weight of the bottom of the entire floating tube unit 300 is increased, so that the floating tube unit 300 floats stably on the sea surface.

[0041] This solution does not limit the connection structure between the floating tube unit 300 and the hexagonal beam unit 400. It can be connected by adhesive bonding or by fixing components. The specific connection structure can be determined according to the actual situation.

[0042] Because the floating tube unit 300 needs to be a sealed structure to ensure the stability of floating, the floating tube unit 300 and the crossbeam unit 400 are preferably bonded together in this scheme.

[0043] See Figure 4The hexagonal beam unit 400 includes a hexagonal beam 410, a third connecting assembly, and beam stiffening ribs 430.

[0044] A third mounting groove 440 is provided at each corner of the hexagonal beam 410 for installing a third connecting assembly. The third connecting assembly includes a third ear plate 421, a third spring support 422, a third anchoring anchor 423, and a fourth anchoring anchor 424.

[0045] The third ear plate 421 is partially disposed within the third mounting groove 440. The third spring support 422 is disposed at both ends of the third ear plate 421, with one end connected to the third mounting groove 440 and the other end connected to the third ear plate 421. The third ear plate 421 is disposed within the third mounting groove 440 via the third spring support 422. By disposing of the third spring base 422 above and below the mounting groove of the third ear plate 421, under the uneven fluctuation of ocean waves, different positions of the photovoltaic support system exhibit different magnitudes and directions of vertical acceleration due to different upward or downward trends. The placement of the third spring base 422 provides the third ear plate 421 with a vertical reaction force opposite to the direction of acceleration, thus playing a role in shock absorption. This prevents the CFRP cables connected through the third ear plate 421 from experiencing uneven internal forces due to the impact load caused by the difference in ocean wave height, and avoids damage to the system nodes caused by the impact of the high and low ocean waves.

[0046] A third anchorage 423 and a fourth anchorage 424 are symmetrically arranged on one side end face of the third ear plate 421 located outside the third mounting groove 440, for use in cooperating with the cable unit 100.

[0047] To ensure the stability of each node of the hexagonal beam 410, this design preferably sets beam stiffening ribs 430 at the nodes. By setting beam stiffening ribs 430, the strength of each node of the hexagonal beam 410 can be guaranteed, which can effectively resist sea waves.

[0048] Further, see Figure 5 The force-bearing unit 200 is located at the center of the hexagonal beam unit 400. It is the central force-bearing point of the entire honeycomb system and plays the role of positioning the CFRP cable axis and connecting the cable units in the structure. It includes a first force-bearing disk 210, a central column 230 and a second force-bearing disk 220. The first force-bearing disk 210 and the second force-bearing disk 220 are respectively set at both ends of the central column 230 to form a symmetrical structure. Several first connecting components and second connecting components are respectively distributed on the first force-bearing disk 210 and the second force-bearing disk 220. Cable units 100 are respectively set on the first connecting components and the second connecting components and connected to the third anchoring anchor 423 and the fourth anchoring anchor 424 on the beam unit 400 to form a cable net structure.

[0049] Specifically, the number of first connecting components corresponding to the number of third connecting components is symmetrically distributed on the side wall of the first force-bearing disk 210, and arranged along the circumference of the first force-bearing disk 210 for connection with the cable unit 100. See the detailed structure below. Figure 6 .

[0050] The first force-bearing disc 210 has a plurality of first mounting slots 240 along its circumference according to the number of first connecting components, and the first connecting components are installed in the first mounting slots 240. The first connecting components include a first ear plate 261, a first anchoring anchor 262, and a first spring support 263.

[0051] The first ear plate 261 is partially disposed within the first mounting groove 240. The first spring support 263 is disposed at both ends of the first ear plate 261, with one end connected to the first mounting groove 240 and the other end connected to the first ear plate 261. The first ear plate 261 is disposed within the first mounting groove 240 via the first spring support 263. By providing the first spring base 263 above and below the mounting groove of the first ear plate 261, under the uneven fluctuation of ocean waves, different positions of the photovoltaic support system exhibit different magnitudes and directions of vertical acceleration due to different upward or downward trends. The provision of the first spring base 263 provides the first ear plate 261 with a vertical reaction force opposite to the direction of acceleration, playing a role in shock absorption. This prevents the CFRP cable connected through the first ear plate 261 from experiencing uneven internal forces due to the impact load caused by the difference in ocean wave height, and avoids damage to the system nodes caused by the impact of the high and low ocean waves.

[0052] Meanwhile, the two force-bearing discs on the force-bearing unit 200 bear the vertical load through the CFRP cable vertical system. Under the action of the waves, the first ear plate 261 and the force-bearing disc are in a state of slight vertical vibration. The setting of the first spring base 263 weakens the fatigue effect of the slight vibration on the CFRP cable.

[0053] A first anchor 262 is provided on one end face of the first ear plate 261 located outside the first mounting groove 240 for connecting with the cable unit 100.

[0054] Correspondingly, a number of second connecting components are distributed on the side of the second force-bearing disk 220 corresponding to the first force-bearing disk 210. The number of second connecting components is symmetrically distributed on the side wall of the second force-bearing disk 220 and arranged along the circumference of the second force-bearing disk 220 for connection with the cable unit 100.

[0055] The second force-bearing disc 220 has several second mounting slots 250 along its circumference, depending on the number of second connecting components. The second connecting components are installed in the second mounting slots 250. The second connecting components include a second ear plate 271, a second anchoring anchor 272, and a second spring support 273.

[0056] The installation structure of the second ear plate 271, the second anchoring anchor 272, and the second spring support 273 in the second mounting groove 250 on the second force-bearing disc 220 is the same as that of the first connecting assembly, and will not be described in detail here.

[0057] In this scheme, the floating tube unit 300 is not set below the force-bearing unit. Instead, it is tightened and fixed by the cable net system formed by the cable unit 100 and the hexagonal beam unit 400. The hexagonal beam unit 400 enables the force-bearing unit 200 to float. While ensuring the stability of the joint force, the structural cost is reduced because there is no need to set the floating tube unit 300 below the force-bearing unit 200.

[0058] See Figure 7 The cable unit 100 includes a first cable 110, a second cable 120, and a third cable 130. The first cable 110, the second cable 120, and the third cable 130 work together to form a cable net system, which pulls and fixes the hexagonal beam unit 400 and the force-bearing unit 200.

[0059] One end of the first cable 110 is connected to the third anchorage 423 on the hexagonal beam unit 400 and the first anchorage 262 on the force-bearing unit 200, respectively. One end of the second cable 120 is connected to the fourth anchorage 424 on the beam unit 400 and the second anchorage 272 on the force-bearing unit 200, respectively.

[0060] The first cable 110 and the second cable 120 are symmetrically arranged to determine the center position of the force-bearing unit 200. After the first cable 110 is tightened, since the centers of the two cables symmetrically located on both sides of the force-bearing disk are on a straight line, the two CFRP cables on the same straight line in the tightened state can be regarded as a single-span cable, and the force-bearing disk is the concentrated load applied to the single-span cable. The tightened second cable 120, on the one hand, assists the first cable 110 in determining the position of the center disk, and on the other hand, the vertical component of the axial force of the inclined second cable 120 can resist the vertical load of the center disk.

[0061] Several support components are distributed between the first cable 110 and the second cable 120. By setting the support components in conjunction with the first cable 110 and the second cable 120, a vertical cable net system is formed to jointly bear the vertical load and fix the force unit. The support components include support cables 140, straight cylindrical bidirectional anchoring clamps 141 and inclined bidirectional anchoring clamps 142.

[0062] A cylindrical bidirectional anchoring clamp 141 is mounted on the first cable 110. One end of the support cable 140 is connected to the first cable 110 via the cylindrical bidirectional anchoring clamp 141. An inclined bidirectional anchoring clamp 142 is mounted on the second cable 120. The other end of the support cable 140 is connected to the second cable 120 via the inclined bidirectional anchoring clamp 142. By setting the support assembly 140, the first cable 110 and the second cable 120 are connected to form a cooperative force-bearing system. Under normal operating conditions, on the one hand, the support cable bears pressure to tighten the first cable 110 and the second cable 120 respectively; on the other hand, the reverse pressure of the support cable 140 on the first cable 110 can also prevent the axis of the first cable 110 from bending vertically under the vertical load of the central disk. Under wave conditions, the support cable can act as a cable to reduce the impact load on the first cable caused by the acceleration of the solar panel.

[0063] Simultaneously, an installation area for the photovoltaic unit 500 is formed between adjacent first cables 110. Three-way anchoring clamps 150 are spaced apart on the first cables 110. The first fixed end of each three-way anchoring clamp 150 is used to pass through the first cable 110 and secure the clamp to the cable. The second and third fixed ends are respectively fitted with third cables 130. Both ends of the third cables 130 are connected to the three-way anchoring clamps 150 on adjacent first cables 110 to form a transverse cable net. This transverse cable net is used for photovoltaic installation. On the one hand, the laying of unit 500 has a large load-bearing area. When subjected to wind, the photovoltaic unit 500 easily generates a large lateral load on the cable net system, which is then transferred to the first cable 110. The various anchoring clamps on the first cable 110 are also affected by wind. Therefore, the third cable 130, which is arranged in a ring around the first cable 110, can withstand the lateral load, preventing lateral vibration of the first cable 110 under windy and wavey weather, and providing lateral support for the first cable 110. This enhances the stability of the cable net system.

[0064] The composition and working principle of the photovoltaic unit 500 are well known to those skilled in the art, and will not be described in detail here.

[0065] Furthermore, the anchorages in this photovoltaic support system are preferably mechanical anchorage nodes, which have a simple structure and are easy to connect.

[0066] Meanwhile, the cable units, load-bearing units, anchorages, beams, and lugs in this photovoltaic support system are all preferably made of CFRP material. CFRP material has high strength and light weight, which can achieve lightweighting of the structural system and reduce the requirements for hexagonal floating tubes. CFRP material also has corrosion resistance, which can prevent corrosion of the system in the marine environment and ensure the reliability and longevity of the system.

[0067] Meanwhile, the first cable, the second cable, and the support cable in this scheme are preferably made of CFRP cable. CFRP cable has a better elastic modulus and can better deform under frequent marine wind loads.

[0068] Based on the honeycomb-shaped floating offshore CFRP cable-supported photovoltaic system provided above, the following example illustrates its assembly process in a specific application. It should be noted that this assembly process is merely illustrative and does not constitute a limitation of this solution. The assembly process includes the following steps:

[0069] (1) Filling inside the float tube 300: A filling hole is provided on the float tube 300. Water is first injected into the interior through the filling hole to the junction of the air filling zone 320 and the water filling zone 310. Then, air is injected into the interior through the filling hole until the float tube 300 expands.

[0070] (2) Place the hexagonal floating tube 300 into seawater, apply epoxy resin adhesive to its surface, place the CFRP hexagonal beam 410 system on the surface of the hexagonal floating tube 300, and wait for the two to be bonded together by the epoxy resin adhesive.

[0071] (3) Then, the CFRP central integrated force-bearing system is suspended at the center of the hexagonal system by a crane.

[0072] (4) Pass the six first CFRP cables 110 through two CFRP straight cylindrical bidirectional mechanical anchoring clamps 141 and several CFRP tridirectional mechanical anchoring clamps 150 respectively and set the clamps in the designated positions. Pass the six second CFRP cables 120 through two CFRP inclined bidirectional mechanical anchoring clamps 142 respectively and set the clamps in the designated positions.

[0073] (4) Install and fix the first mechanical anchor and the second mechanical anchor at one end of the six first CFRP cables and the six second CFRP cables respectively. Then, use the first mechanical anchor and the second mechanical anchor to connect one end of the first CFRP cable 110 and the second CFRP cable 120 to the first ear plate 261 and the second ear plate 271 on the CFRP central integrated force system by bolts.

[0074] The other ends of the six first CFRP cables 110 and the six second CFRP cables 120 are respectively provided with third and fourth mechanical anchorages. The other ends of the first CFRP cables 110 and the second CFRP cables 120 are bolted to the fourth anchorage 423 and the fifth anchorage 424 of the third ear plate 421 on the hexagonal beam. The CFRP support cable 140 is connected to the first cable 110 and the second cable 120 respectively through the CFRP straight cylindrical bidirectional mechanical anchorage clamp 141 and the CFRP inclined bidirectional mechanical anchorage clamp 142, forming a coordinated force-bearing system of the first CFRP cables 110 and the second CFRP cables 120, which jointly bear the vertical load and fix the CFRP center integrated force-bearing system.

[0075] (5) The third CFRP cable 130 is threaded onto the CFRP three-way mechanical anchoring clamp 150 at the designated position, and both ends are connected to the adjacent first cable 110 respectively to form a transverse cable net structure of the honeycomb floating marine CFRP cable-supported photovoltaic support system.

[0076] (6) Finally, the solar panel 500 is assembled on the third CFRP cable 130, the crane force is removed, and the single honeycomb floating marine CFRP cable-supported photovoltaic bracket system is assembled.

[0077] (7) Different numbers of the system can be assembled according to the needs, and several honeycomb floating marine CFRP cable-supported photovoltaic support systems can be spliced ​​together to form a honeycomb structure system for use.

[0078] The honeycomb-shaped floating marine CFRP cable-supported photovoltaic support system constructed by the above scheme has a honeycomb system form that facilitates the formation of a collaborative system of multiple photovoltaic support systems. The system has a large span, which is convenient for construction and use in marine environments. Moreover, the structure is simple and has the characteristics of modular construction, which makes construction relatively convenient. At the same time, the large-scale collaborative system also facilitates the management and inspection of photovoltaic support systems.

[0079] Secondly, the system has a simple support structure, high modularity and reliability, which can keep the solar panels in a horizontal and stable state while floating, thus improving their resistance to wave impact in the marine environment.

[0080] In addition, the support system uses CFRP cables and CFRP components as the main load-bearing components, which can effectively solve the corrosion problem in the marine environment.

[0081] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
