Technical Field

[0003] This application relates to the field of floating photovoltaic power generation, and more particularly to a photovoltaic power station and its floating photovoltaic power generation system. Background Technology

[0004] Floating photovoltaic power stations are built on water, thus avoiding competition for land resources with agriculture or other uses. On one hand, the open water surface and high reflectivity prevent the negative impact of shadows on photovoltaic module power generation. On the other hand, the water surface has a cooling effect, effectively reducing the operating temperature of the photovoltaic modules and thus minimizing temperature losses in the photovoltaic power generation system. Furthermore, the shading provided by floating photovoltaic power stations can inhibit algae growth, contributing positively to water purification and thus protecting and improving the aquatic environment.

[0005] In related technologies, the floating bodies of a floating photovoltaic power station are connected together by a fixed connection and float on the water surface. However, due to severe weather conditions such as strong convective winds, hail, and short-term heavy rainfall, the floating bodies are prone to detachment, which affects the stability of the floating photovoltaic power station.

Detailed Implementation

[0047] Referring to Figures 1 and 2, this application embodiment provides a floating photovoltaic power generation system 1000, which includes: a support unit 1100, a connecting unit 1200, and a plurality of floating body units 1300 arranged in a preset manner. Referring to Figure 16, a reinforcing member 1800 is provided in the floating body unit 1300. The support unit 1100 is disposed on the bearing surface of the floating body unit 1300. The support unit 1100 is used to install photovoltaic modules 1700, and the support unit 1100 is at least partially integrally formed with the floating body unit 1300. Referring to Figure 4, the connecting unit 1200 includes: a first connecting member 1210. The first connector 1210 is disposed on the float unit 1300, and the first connector 1210 connects two adjacent float units 1300 so that the two adjacent float units 1300 are elastically connected along a first preset direction and a second preset direction. The first connector 1210 is detachably connected to the float unit 1300, and the first preset direction is perpendicular to the second preset direction. The floating unit 1300 is provided with a reinforcing member 1800 to enhance the structural stability of the floating unit 1300 and improve its load-bearing capacity when floating. The support unit 1100 is at least partially integrally formed with the floating unit 1300. This reduces the number of components required for the photovoltaic module 1700 during installation, improving assembly efficiency. It also increases the stability of the relative position between the support unit 1100 and the floating unit 1300. Furthermore, the elastic connection between adjacent floating units 1300 buffers the impact of water on the floating units 1300, enhancing the stability of the connection and improving the ability of adjacent floating units 1300 to resist severe weather, thus facilitating the continuous and stable operation of the floating photovoltaic power generation system 1000.

[0048] In some embodiments, a plurality of the floating body units 1300 are connected by the connecting unit 1200 to be arranged in a rectangular array.

[0049] Referring to Figure 4, in some embodiments, the float unit 1300 includes: a first float 1310, a second float 1320, and a third float 1330. The first float 1310 is disposed along a first preset direction, and two first floats 1310 are disposed opposite each other. The second float 1320 is disposed along the second preset direction, and the second float 1320 connects the two first floats 1310, and two second floats 1320 are disposed opposite each other. The third float 1330 is disposed along the first preset direction, and the third float 1330 connects the middle ends of the two second floats 1320.

[0050] Referring to Figure 16, in some embodiments, the first float 1310 has a first float cavity. The second float 1320 has a second float cavity. The reinforcing member 1800 is disposed in the first float 1310 to divide the first float cavity into a plurality of first sub-float cavities. The reinforcing member 1800 is disposed in the second float 1320 to divide the second float cavity into a plurality of second sub-float cavities. The reinforcing member 1800 improves the structural stability of the first float 1310 and the second float 1320, and enhances their bending and tensile strength. On the other hand, under the same volume conditions, compared with a single float cavity, multiple sub-float cavities can reduce the amount of water entering the first float 1310 and the second float 1320 when damaged, and can slow down the rate of buoyancy decline of the first float 1310 and the second float 1320 when damaged, thereby improving the ability of the first float 1310 and the second float 1320 to resist wind and waves when floating.

[0051] In some embodiments, the number of the reinforcing members 1800 in the first float 1310 is eight, and each of the reinforcing members 1800 is arranged in the first float 1310 along the first preset direction, and the axis of symmetry of each of the reinforcing members 1800 coincides with the axis of symmetry of the first float 1310.

[0052] In other embodiments, the number of reinforcing members 1800 in the first float 1310 may be two, four, six, ten, twelve, etc., which will not be listed here.

[0053] Referring to Figures 4 and 16, in some embodiments, the first float 1310 includes a first support portion 1311, a second support portion 1312, and a containment portion 1313. The first support portion 1311 and the second support portion 1312 are disposed opposite to each other. The containment portion 1313 is disposed around the periphery of the first support portion 1311, and the containment portion 1313 connects the first support portion 1311 and the second support portion 1312 to form the first float cavity with the first support portion 1311 and the second support portion 1312.

[0054] In some embodiments, the first support portion 1311 has a first support surface. The second support portion 1312 has a second support surface. When the first float 1310 unit floats on the water surface, the first support surface is in contact with the water, and the support unit 1100 is disposed on the second support surface.

[0055] In some embodiments, the enclosure portion 1313 is provided with a first connecting area and a second connecting area. The first connecting area is located on the end face of the first float 1310. The second connecting area is located on the side of the first float 1310.

[0056] Referring to Figure 4, in some embodiments, receiving grooves 1314 are provided on the first connection area and the second connection area. A connecting block 1315 is provided in the receiving groove 1314, and the connecting block 1315 is detachably connected to the receiving groove 1314. The first connector 1210 connects two adjacent connecting blocks 1315.

[0057] In some embodiments, the receiving groove 1314 on the first connection area extends in a constricted manner along the first preset direction. The receiving groove 1314 on the second connection area extends in a constricted manner along the second preset direction.

[0058] In some embodiments, the length of the receiving groove 1314 along a third preset direction is less than the length of the first float 1310 along the third preset direction, the length of the receiving groove 1314 along a second preset direction is less than the length of the first float 1310 along the second preset direction, and the length of the receiving groove 1314 along the first preset direction is less than the length of the first float 1310 along the first preset direction. The third preset direction is perpendicular to the first preset direction, and the third preset direction is perpendicular to the second preset direction.

[0059] Referring to Figures 5, 6, and 13, in some embodiments, the two connecting blocks 1315 include a first connecting block 1316 and a second connecting block 1317 disposed opposite to each other. One end of the first connecting member 1210 is connected to the first connecting block 1316, and the other end of the first connecting member 1210 away from the first connecting block 1316 is connected to the second connecting block 1317. One end of the first connecting member 1210 is connected to the corresponding first float 1310 through the first connecting block 1316, and the other end of the first connecting member 1210 is connected to the corresponding first float 1310 through the second connecting block 1317.

[0060] Referring to Figures 5 and 6, in some embodiments, the first connector 1210 includes a connecting rope 1211 and an elastic portion 1212. The elastic portion 1212 is sleeved on the outside of the connecting rope 1211, and one end of the elastic portion 1212 is connected to the first connecting block 1316, while the end of the elastic portion 1212 away from the first connecting block 1316 is connected to the second connecting block 1317.

[0061] Understandably, when two adjacent first floats 1310 move towards each other due to wind and waves, the elastic part 1212 is compressed, which can buffer the impact and prevent collisions between the two adjacent first floats 1310. When two adjacent first floats 1310 move away from each other due to wind and waves, the elastic part 1212 can effectively reduce the tension on the connecting rope 1211 by stretching and deforming, thereby effectively increasing the service life of the connecting rope 1211.

[0062] In some embodiments, the first connector 1210 can realize elastic constraints with multiple degrees of freedom such as tension, compression, bending, shearing, and torsion.

[0063] In some embodiments, the elastic portion 1212 is a spring rubber. The elastic portion 1212 connects two adjacent first floats 1310 so that the two adjacent first floats 1310 are elastically connected, thereby buffering the impact of the water surface on the two adjacent first floats 1310 and improving the ability of the first floats 1310 to resist severe weather such as convective winds, hail, and short-term heavy rainfall.

[0064] In other embodiments, the elastic part 1212 is a PU (polyurethane) part to improve the wear resistance, corrosion resistance and strong compressive strength of the elastic part 1212.

[0065] Please refer to Figures 5 and 7. In some embodiments, the elastic portion 1212 has a first connecting end 1212a and a second connecting end 1212b at opposite ends. The first connecting end 1212a is connected to the first connecting block 1316, and the second connecting end 1212b is connected to the second connecting block 1317. This allows the elastic portion 1212 to be squeezed when two adjacent first floats 1310 move toward each other, and to be stretched when two adjacent first floats 1310 move away from each other.

[0066] Referring to Figure 7, in some embodiments, the first connecting end 1212a passes through the first connecting block 1316, so that the end of the elastic portion 1212 away from the second connecting block 1317 is connected to the first connecting block 1316. The second connecting end 1212b passes through the second connecting block 1317, so that the end of the elastic portion 1212 away from the first connecting block 1316 is connected to the second connecting block 1317.

[0067] In some embodiments, the connecting rope 1211 is a steel wire rope or a polymer rope with a certain degree of elasticity.

[0068] In some embodiments, the connecting rope 1211 includes multiple twisted monofilaments, that is, the connecting rope 1211 is made of multiple twisted monofilaments, so as to improve the reliability of the connecting rope 1211 during operation and to improve the service life of the connecting rope 1211.

[0069] Referring to Figure 7, in some embodiments, the first connector 1210 further includes a first limiting portion 1213 and a second limiting portion 1214. The first limiting portion 1213 is disposed on the first connecting block 1316 and connected to one end of the connecting rope 1211. The second limiting portion 1214 is disposed on the second connecting block 1317 and connected to the end of the connecting rope 1211 away from the first connecting block 1316.

[0070] In some embodiments, one end of the connecting rope 1211 is connected to the first connecting block 1316 via the first limiting part 1213, and the other end of the connecting rope 1211 is connected to the second connecting block 1317 via the second limiting part 1214.

[0071] Referring to Figure 7, in some embodiments, the end of the connecting rope 1211 connected to the first limiting part 1213 and the first limiting part 1213 are both pre-embedded in the first connecting block 1316, so that the end of the connecting rope 1211 away from the second connecting block 1317 is fixedly connected to the first connecting block 1316. Similarly, the end of the connecting rope 1211 connected to the second limiting part 1214 and the second limiting part 1214 are both pre-embedded in the second connecting block 1317, so that the end of the connecting rope 1211 away from the first connecting block 1316 is fixedly connected to the second connecting block 1317.

[0072] In some embodiments, both the first limiting part 1213 and the second limiting part 1214 are steel bars. Referring to Figure 9, one end of the connecting rope 1211 has a first knot, and the other end has a second knot. The first knot is fitted onto the first limiting part 1213, is embedded within the first connecting block 1316, and is connected to the first limiting part 1213. The second knot is fitted onto the second limiting part 1214, is embedded within the second connecting block 1317, and is connected to the second limiting part 1214.

[0073] In other embodiments, the first limiting part 1213 and the second limiting part 1214 are both steel plates to increase the contact area between the first limiting part 1213 and the first connecting block 1316, and the contact area between the second limiting part 1214 and the second connecting block 1317.

[0074] In some embodiments, one end of the connecting rope 1211 is fixedly connected to the first limiting part 1213 by welding, and the other end of the connecting rope 1211 is fixedly connected to the second limiting part 1214 by welding.

[0075] In some embodiments, both the first connecting block 1316 and the second connecting block 1317 are concrete components. Both the first connecting block 1316 and the second connecting block 1317 are wedge-shaped to improve the reliability of their connection with the first float 1310.

[0080] In some embodiments, one end of the connecting rope 1211 passes through the first positioning part 1215b and the first fixing part 1215, and is connected to the first connecting block 1316. The other end of the connecting rope 1211, away from the first connecting block 1316, passes through the second positioning part 1216b and the second fixing part 1216, and is connected to the second connecting block 1317. The connecting rope 1211 is used to connect the first connecting block 1316 and the second connecting block 1317, thereby connecting the two first floats 1310.

[0081] In some embodiments, the first positioning portion 1215b has a first cavity inside. The second positioning portion 1216b has a second cavity inside. One end of the connecting rope 1211 passes through the first cavity and is connected to the first connecting block 1316. The end of the connecting rope 1211 away from the first positioning portion 1215b is located in the second cavity and is connected to the second connecting block 1317 to prevent the connecting rope 1211 from interfering with the inner side of the elastic portion 1212 when stretched or contracted.

[0082] In some embodiments, one end of the connecting rope 1211 is in clearance fit with the inner wall of the first cavity, and the other end is in clearance fit with the inner wall of the second cavity.

[0087] In some embodiments, the inner diameter of the third cavity is smaller than the inner diameter of the first cavity, and the inner diameter of the third cavity matches the outer diameter of the connecting rope 1211; the inner diameter of the fourth cavity is smaller than the inner diameter of the second cavity, and the inner diameter of the fourth cavity matches the outer diameter of the connecting rope 1211, in order to prevent the connecting rope 1211 from swaying.

[0088] Referring to Figure 15, in some embodiments, the connecting unit 1200 further includes an anti-wear component 1230. The anti-wear component 1230 is disposed between the first float 1310 and the first connecting block 1316 to prevent the first float 1310 from rubbing against the first connecting block 1316 when subjected to wind and waves.

[0089] Referring to Figure 14, in some embodiments, the connecting unit 1200 further includes a mounting member 1240. One end of the mounting member 1240 is fixed inside the first float 1310, and the other end is connected to the receiving groove 1314, so that the first connecting block 1316 is placed inside the receiving groove 1314 and connected to the corresponding first float 1310.

[0090] For example, the mounting component 1240 is U-shaped, and one end of the mounting component 1240 is embedded in the first float 1310, while the other end is connected to the first connecting block 1316 by a bolt structure.

[0091] In some embodiments, at least a portion of the second connecting block 1317 is pre-embedded within the corresponding first float 1310, so that the second connecting block 1317 is fixedly connected to the corresponding first float 1310. In another embodiment, the second connecting block 1317 is fixedly connected to the corresponding first float 1310 via the mounting member 1240.

[0092] Referring to Figures 4 and 18, in some embodiments, the support unit 1100 includes: a support base 1110, a suspension cable 1120, and a fixing member 1130. The support base 1110 is disposed on the first float 1310 and integrally formed with the first float 1310, and the support base 1110 is provided with a mounting hole. The mounting hole penetrates the support base 1110 along a second preset direction. The fixing member 1130 is disposed on the support base 1110. The suspension cable 1120 passes through the mounting hole and is detachably connected to the fixing member 1130, and the suspension cable 1120 has a preset prestress. The photovoltaic module 1700 is mounted on the suspension cable 1120.

[0093] Referring to Figures 17 and 18, in some embodiments, the support base 1110 includes a first base body 1111 and a second base body 1112. Two first base bodies 1111 are arranged opposite each other, and each first base body 1111 is respectively disposed on a corresponding first float 1310 and integrally formed with the first float 1310. Two second base bodies 1112 are also arranged opposite each other, and each second base body 1112 is respectively disposed on a corresponding first float 1310 and integrally formed with the first float 1310. The integral formation of the first base body 1111 and the second base body 1112 with the first float 1310 reduces the number of components that need to be assembled during the installation of the photovoltaic module 1700 and increases the stability of the positions of the first base body 1111 and the second base body 1112.

[0094] In some embodiments, the length of the first seat 1111 along the third preset direction is less than the length of the second seat 1112 along the third preset direction.

[0095] In some embodiments, the distance between the mounting hole on the first base 1111 and the second bearing surface is smaller than the distance between the mounting hole on the two bases and the second bearing surface, thereby causing the photovoltaic modules 1700 on the two suspension cables 1120 to have a preset tilt angle.

[0096] Referring to Figure 1, in some embodiments, the floating photovoltaic power generation system 1000 further includes a support unit 1400. The support unit 1400 is disposed on the third float 1330, and the support unit 1400 is detachably connected to the third float 1330. The support unit 1400 is used to support the middle end of the suspension cable 1120 to improve the stability of the installation position of the photovoltaic module 1700.

[0097] Referring to Figures 1 and 19, in some embodiments, the support unit 1400 includes: a first base 1410, a first support rod 1420, and a second support rod 1430. The first base 1410 is detachably connected to the third float 1330. The first support rod 1420 is disposed on the first base 1410, and the first support rod 1420 is an inclined rod, with two first support rods 1420 arranged opposite to each other. The second support rod 1430 is disposed on the first support rod 1420. The middle end of the suspension cable 1120 abuts against the second support rod 1430.

[0098] In some embodiments, the second support rod 1430 is disposed along the first preset direction, and the second support rod 1430 is a square rod. The first support rod 1420 is a round rod.

[0099] In some embodiments, the axes of symmetry of the two first support rods 1420 are perpendicular to the second support rod 1430. A preset angle exists between the second support rod 1430 and the first base 1410. The preset angle is equal to the preset tilt angle.

[0100] Referring to Figure 3, in some embodiments, the connecting unit 1200 further includes a second connector 1220. The second connector 1220 is disposed along the first preset direction, the second connector 1220 connects two adjacent second floats 1320, and the second connector 1220 is located between the two third floats 1330.

[0101] In some embodiments, the number of the second connectors 1220 between the two second floats 1320 is two, the two second connectors 1220 are symmetrically arranged on the two second floats 1320, and the axis of symmetry of the two second connectors 1220 coincides with the centerline of the second float 1320.

[0102] In other embodiments, the number of the second connectors 1220 between the two second floats 1320 can also be four, six, eight, ten, etc., which will not be listed here.

[0103] In some embodiments, the second connector 1220 is a rope.

[0104] Referring to Figure 3, in some embodiments, a second base 1500 is provided on the second float 1320. The second base 1500 is detachably connected to the second float 1320, and a lifting ring 1600 is provided on the second base 1500. The lifting ring 1600 is detachably connected to the second base 1500. The second connector 1220 passes through the lifting ring 1600 to connect the two second floats 1320, thereby enhancing the stability of the connection between the two second floats 1320 and further enhancing the stability of the connection between adjacent float units 1300.

[0105] The reinforcing member 1800 enhances the structural stability of the first float 1310 and the second float 1320, and slows down the rate of buoyancy decline of the first float 1310 and the second float 1320 in the event of damage, effectively improving their ability to resist wind and waves when floating. The first base 1111 is integrally formed with the first float 1310, and the second base 1112 is integrally formed with the first float 1310, reducing the number of components required for the installation of the photovoltaic module 1700 and increasing the positional stability of the first base 1111 and the second base 1112. The second connector 1220 connects the two second floats 1320, enhancing the stability of the connection between the two second floats 1320 and the stability of the connection between adjacent float units 1300. The first connector 1210 connects two adjacent first floats 1310 so that the two adjacent first floats 1310 are elastically connected, which can buffer the impact of the water surface on the two adjacent first floats 1310, improve the ability of the two adjacent float units 1300 to resist severe weather such as convective winds, hail, and short-term heavy rainfall, and enhance the stability of the connection between the two adjacent float units 1300.
