[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] like Figure 1-20 As shown, the bearing system of the floating photovoltaic power station provided by an embodiment of the present invention includes: a walkway float 4 that provides buoyancy and forms a first operation and maintenance channel, the walkway float 4 is provided with a fixing portion 402 for being fixedly connected to the front side of the photovoltaic module 3, and one photovoltaic module 3 is only fixedly connected to one walkway float 4 located on the front side thereof.

[0051] It can be understood that the front side of the photovoltaic component 3 only refers to one side of the photovoltaic component 3 and has no limitation on the front-to-back direction.

[0052] The bearing system of the floating photovoltaic power station provided in the embodiment of the present invention adopts a walkway float 4 that provides buoyancy and forms a first operation and maintenance channel and is fixedly connected to the front side of the photovoltaic module 3. The walkway float 4 has two functions of supporting the photovoltaic module 3 and providing buoyancy. Compared with the prior art in which the float only provides buoyancy, the number of components is reduced, thereby effectively reducing the cost.

[0053] At the same time, in the bearing system of the floating photovoltaic power station provided by the embodiment of the present invention, when wave fluctuations cause displacement differences between adjacent walkway floats 4, since one photovoltaic module 3 is only fixedly connected to one walkway float 4 located in front of it, the influence of the displacement difference on the single photovoltaic module 3 is effectively reduced, thereby reducing the probability of the photovoltaic module 3 being damaged and improving the service life of the photovoltaic module 3.

[0054] The fixing portion 402 of the above-mentioned walkway float 4 is used to be fixedly connected to the front side of the photovoltaic component 3. Specifically, the fixing portion 402 can be directly fixedly connected to the front side of the photovoltaic component 3, or can be indirectly fixedly connected through other components, which is not limited in the embodiment of the present invention.

[0055] In the above-mentioned bearing system of the floating photovoltaic power station, one photovoltaic module 3 is fixedly connected to only one walkway floating body 4 located in front of it, including two situations: one is that the walkway floating body 4 located in front of the photovoltaic module 3 corresponds to the photovoltaic module 3 one by one, and the other is that the walkway floating body located in front of the photovoltaic module 3 corresponds to at least two photovoltaic modules 3. In order to minimize the influence of the above-mentioned displacement difference on the photovoltaic module 3, the first situation is preferred, that is, the photovoltaic module 3 corresponds to the walkway floating body 4 located in front of it one by one.

[0056] In order to improve the stability of the fixed connection between the photovoltaic component 3 and the walkway float 4, the walkway float 4 is provided with a hook 406 for cooperating with the clamping hole of the photovoltaic component 3 to prevent the photovoltaic component 3 from being separated.

[0057] Of course, stability may also be improved by other means. For example, the walkway float 4 is provided with a first pressing portion 405 for pressing the photovoltaic assembly 3 onto the fixing portion 402 .

[0058] In order to maximize the stability, it is preferred that the above-mentioned walkway float 4 is provided with a hook 406 and a first pressing portion 405 at the same time. Fig.10 shown.

[0059] The specific structures and numbers of the fixing portion 402 , the hook 406 and the first pressing portion 405 are selected according to actual needs, and are not limited in this embodiment of the present invention.

[0060] like Fig.15 As shown, the bearing system of the floating photovoltaic power station further includes an auxiliary floating body 12 arranged in parallel with the walkway floating body 4 and forming a second operation and maintenance channel, and the auxiliary floating body 12 is fixedly connected to the walkway floating body 4. Specifically, the auxiliary floating body 12 and the walkway floating body 4 can be directly fixedly connected or indirectly fixedly connected.

[0061] It can be understood that the auxiliary floating body 12 is located on one side of the walkway floating body 4 and on the bottom side of the photovoltaic assembly 4. By adjusting the number of the auxiliary floating bodies 12, the buoyancy of the entire bearing system can be adjusted.

[0062] In the above structure, the auxiliary floating body 12 is provided to facilitate maintenance of the photovoltaic assembly 3 .

[0063] The structure of the auxiliary float 12 can refer to the walkway float 4. There may be a gap or no gap between the auxiliary float 12 and the walkway float 4. In order to increase the exposed part of the bottom side of the photovoltaic module 3, it is preferred to have a gap between the auxiliary float 12 and the walkway float 4. The size of the gap is selected according to actual needs, and the embodiment of the present invention does not limit this.

[0064] In order to increase the power generation of the floating photovoltaic power station, the above-mentioned walkway buoys 4 are at least two and arranged in rows along a set direction, and two adjacent walkway buoys 4 in each row are fixedly connected. In this way, at least two photovoltaic modules 3 can be carried, thereby increasing the power generation.

[0065] In actual application, the set direction may be selected as the length direction or the width direction of the walkway float 4. In order to facilitate the fixed connection of two adjacent walkway floats 4 in each row of walkway floats 4, the two ends of the walkway float 4 are provided with second connection ears 403.

[0066] Of course, it is also possible to select at least two of the above-mentioned walkway floating bodies 4 and distribute them in a row. At this time, components need to be set to connect adjacent walkway floating bodies 4.

[0067] The above-mentioned walkway floats 4 can be in one row or at least in two rows. When the walkway floats 4 are in at least two rows, in order to ensure the connection of each row of walkway floats 4, the bearing system of the above-mentioned floating photovoltaic power station also includes: a connecting cover plate 5 fixedly connected to the end of each row of walkway floats 4, and an equipment float 6 fixedly connected to two adjacent connecting cover plates 5. At this time, a second connecting ear 403 of the walkway float 4 located at the end of each row is fixedly connected to the connecting cover plate 5. When auxiliary floats 12 are provided, the auxiliary floats 12 are also distributed in rows along the above-mentioned set direction, and it is preferred that the connecting cover plate 5 is fixedly connected to the auxiliary floats 12 at the end of each row.

[0068] Preferably, the above-mentioned equipment floats 6 and connection covers 5 are distributed at both ends of each row of walkway floats 4. In this way, walking and installation can be carried out from both ends of each row of walkway floats 4, which improves flexibility.

[0069] Specifically, the two ends of the equipment float 6 are provided with third connection ears 601, and the connection cover plate 5 is provided with mounting holes to achieve fixed connection between the connection cover plate 5 and the equipment float 6, and between the connection cover plate 5 and the walkway float 4. Of course, other structures are also used to achieve fixed connection, and are not limited to this.

[0070] The specific structures of the above-mentioned walkway float 4, auxiliary float 12, connection cover plate 5 and equipment float 6 are designed according to actual needs. Preferably, at least one of the above-mentioned walkway float 4, auxiliary float 12, connection cover plate 5 and equipment float 6 is a hollow structure, and the hollow structure includes a closed shell, and the closed shell has a closed cavity, and the closed cavity is a cavity or the closed cavity is provided with a filler. It can be understood that the density of the above-mentioned filler is relatively small, for example, the density of the filler is less than the density of water.

[0071] In the above-mentioned bearing system of the floating photovoltaic power station, in each row of walkway floats 4, two adjacent walkway floats 4 can be directly fixedly connected or indirectly fixedly connected. The two adjacent walkway floats 4 in each row are indirectly fixedly connected, specifically, the two adjacent walkway floats 4 in each row are indirectly fixedly connected through a connecting component, and the connecting component can be a connecting float that can provide buoyancy. Of course, the above-mentioned connecting component can also be selected as a component that does not provide buoyancy, and the embodiment of the present invention does not limit this.

[0072] In order to further optimize the above technical solution, the bearing system of the above floating photovoltaic power station also includes a support frame fixedly connected to the rear side of the photovoltaic module 3, one end of the support frame is fixedly connected to the walkway float 4 located on the front side of the photovoltaic module 3, and the other end of the support frame is fixedly connected to the walkway float 4 located on the rear side of the photovoltaic module 3.

[0073] It can be understood that the support frame is provided with a mounting portion for being fixedly connected to the rear side of the photovoltaic assembly 3. The rear side of the photovoltaic assembly 3 is opposite to the front side of the photovoltaic assembly 3, that is, the front side and the rear side of the photovoltaic assembly 3 can be set at the same height or at different heights. In order to improve the power generation efficiency, it is preferred that the front side and the rear side of the photovoltaic assembly 3 are set at different heights. Specifically, the front side of the photovoltaic assembly 3 is higher than the rear side of the photovoltaic assembly 3, or the front side of the photovoltaic assembly 3 is lower than the rear side of the photovoltaic assembly 3. At this time, the mounting portion on the support frame and the fixing portion 402 on the walkway float 4 are not set at the same height.

[0074] Specifically, when the auxiliary floating body 12 is provided, it is preferred that the auxiliary floating body 12 is fixedly connected to the walkway floating body 4 via a support frame. Specifically, the auxiliary floating body 12 is fixedly connected to the support frame.

[0075] After the photovoltaic module 3 is installed on the supporting system of the above-mentioned floating photovoltaic power station, the exposed part of the bottom side of the photovoltaic module 3 can be increased, thereby increasing the air flow between the photovoltaic module and the water surface, improving the cooling effect, reducing the working temperature of the photovoltaic module, and improving the power generation efficiency; it can also meet the needs of double-sided power generation components and improve versatility.

[0076] There are two types of relative positional relationships between the support frame and the walkway float 4. One is that the support frame spans the walkway float 4. Figure 6-8 , Fig.15 Another support frame does not span the walkway buoy 4, that is, in the length direction of the support frame, the support frame is located between two adjacent walkway buoys 4, such as Figure 16-18 shown.

[0077] In the bearing system of the floating photovoltaic power station, only one of the methods can be selected, or both of the above methods can be selected.

[0078] When the support frame crosses the walkway float 4, in order to facilitate the crossover, the walkway float 4 is provided with a clearance groove 401 for accommodating the support frame. In order to facilitate installation, the walkway float 4 is provided with a first connection ear 404. Fig. 9 As shown, the first connecting ears 404 are located at both ends of the clearance groove 401 , and the first connecting ears 404 are fixedly connected to the connecting rod 2 .

[0079] When the bearing system of the above-mentioned floating photovoltaic power station is in use, wave fluctuations will cause displacement differences between adjacent rows of walkway floats 4, and the displacement differences will be directly transmitted to the photovoltaic modules 3, causing the photovoltaic modules 3 to produce a certain amount of deformation. When the deformation exceeds a certain range, the photovoltaic modules 3 will be irreversibly damaged. For example, hidden cracks that cannot be observed by the naked eye will occur inside the photovoltaic modules 3, resulting in low power generation efficiency.

[0080] In order to overcome the above problems, when the support frames span the walkway float 4, there are at least two support frames, and the support frames are opposite to each other end to end. The two support frames opposite to each other end to end are connected by rotation in a vertical plane. At this time, the support frames are opposite to each other end to end along their length directions, and the rotation axis of the support frames is parallel to or relatively inclined to the width direction of the support frames.

[0081] It can be understood that the two support frames are opposite each other end to end, which means that the head end of one support frame is opposite to the tail end of the other support frame. In the two support frames opposite each other end to end, the head end of one support frame is rotatably connected to the tail end of the other support frame.

[0082] There are many structures to realize the above-mentioned rotational connection. In order to simplify the structure, it is preferred to realize it through a rotating shaft. Specifically, of the two supporting frames facing each other end to end, a first connecting piece 7 is fixed on one supporting frame, and a second connecting piece 10 is fixed on the other supporting frame. The second connecting piece 10 and the first connecting piece 7 are rotationally connected through a first rotating shaft 9, and the first rotating shaft 9 is rotatably arranged on one supporting frame. For ease of installation, it is preferred that the above-mentioned first connecting piece 7 is fixed to one supporting frame through a first pin shaft 8, and the second connecting piece 10 is fixed to the other supporting frame through a second pin shaft 11.

[0083] Furthermore, there are two first connecting pieces 7 respectively located on both sides of one support frame, and there are two second connecting pieces 10 respectively located on both sides of another support frame. This improves stability and prevents the support frame from moving along its width direction during rotation.

[0084] When the support frame is located between two adjacent walkway buoys 4 in the length direction of the support frame, in order to overcome the above problem, the support frame includes: a support frame body 201, and a connection portion fixedly connected to the walkway buoy 4; wherein there are two connection portions, which are respectively connected to the two ends of the support frame body 201, and at least one connection portion is rotatably connected to the support frame body 201 in a vertical plane. At this time, the rotation axis of the connection portion is parallel to or relatively inclined to the width direction of the support frame body 201.

[0085] Preferably, at least one connection portion is provided with a limiter 206 for limiting the movement of the support frame body 201 along its width direction. In this way, the support frame is prevented from moving along its width direction during rotation, thereby improving stability. In order to improve the limiting reliability, it is preferred to select a connection portion that is rotatably connected to the support frame body 201 and provide a limiter 206.

[0086] Specifically, Figure 18-20As shown, the two connecting parts are respectively a first connecting part 202 and a second connecting part 203, the first connecting part 202 is fixedly connected to the support frame body 201, the second connecting part 203 is provided with a second rotating shaft 205, the support frame body 201 is rotatably provided on the second rotating shaft 205, and the stopper 206 is provided on the second connecting part 203. For the convenience of installation, the first connecting part 202 and the support frame body 201 are fixedly connected through a third pin shaft 204.

[0087] Of course, other structures may also be used to achieve rotational connection, and are not limited to the above embodiments.

[0088] It should be noted that the vertical plane mentioned in this article is perpendicular to the water surface, and the water surface refers to a waveless water surface.

[0089] In order to improve the stability of the fixed connection between the support frame and the walkway float 4, the support frame is further provided with a second pressing portion 1016 for pressing the photovoltaic assembly 3 onto the support frame.

[0090] The second pressing portion 1016 may be a pressing plate, a pressing block or other structures. The specific structure of the second pressing portion 1016 is selected according to actual needs, and the embodiment of the present invention does not limit this.

[0091] In the bearing system of the above-mentioned floating photovoltaic power station, the specific structure of the support frame is selected according to actual needs. Preferably, the above-mentioned support frame includes: a connecting rod 2, and a bracket 1 fixedly connected to the connecting rod 2; wherein the bracket is used to be fixedly connected to the rear side of the photovoltaic module 3, one end of the connecting rod 2 is fixedly connected to the walkway floating body 4 located on the front side of the photovoltaic module 3, and the other end of the connecting rod 2 is fixedly connected to the walkway floating body 4 located on the rear side of the photovoltaic module 3.

[0092] In the above structure, when the support frame includes: a support frame body 201 and a connecting portion, the support frame body 201 includes a portion of the connecting rod 2 and the bracket 1 , and the connecting portion is the two end portions of the connecting rod 2 .

[0093] The structure of the above-mentioned support frame is simpler, and the area of ​​the water surface shielded is also smaller. Of course, the above-mentioned support frame can also be selected to be other structures, and is not limited to this.

[0094] The bearing system of the floating photovoltaic power station can adjust the inclination angle of the photovoltaic module 3 by adjusting the position of the bracket 1 on the connecting rod 2, thereby improving flexibility; moreover, the photovoltaic module 3 can be set at a larger inclination angle to meet the use requirements of high-latitude areas.

[0095] In order to facilitate adjustment of the inclination angle of the photovoltaic assembly 3 , the bracket 1 is detachably fixedly connected to the connecting rod 2 .

[0096] The bracket 1 may be V-shaped or in other shapes, which is not limited in the embodiment of the present invention.

[0097] The bracket 1 can be an integrated structure or a split structure. In order to facilitate manufacturing and production, the bracket 1 is preferably a split structure. Figure 1-5 As shown, the bracket 1 preferably includes: a first sub-frame body 101 and a second sub-frame body 102 that are spliced ​​and fixedly connected, and the first sub-frame body 101 and the second sub-frame body 102 form a mounting structure at the splicing position, and the connecting rod 2 passes through the mounting structure.

[0098] Of course, the bracket 1 may also be selected as other types of split structures, and is not limited to the above embodiments.

[0099] The first sub-frame body 101 and the second sub-frame body 102 can be spliced ​​first and then fixedly connected, or they can be fixedly connected while being spliced. For ease of installation, the former is preferred. For ease of maintenance, the first sub-frame body 101 and the second sub-frame body 102 are detachably fixedly connected. When the bracket 1 is V-shaped, the splicing point of the first sub-frame body 101 and the second sub-frame body 102 is located at the tip of the V-shape.

[0100] The above-mentioned bracket 1 is designed as a split structure, so the first sub-frame body 101 and the second sub-frame body 102 can be produced first, and then the first sub-frame body 101 and the second sub-frame body 102 can be spliced ​​and fixedly connected. Compared with directly producing the entire integrated bracket, the mold volume is effectively reduced, the production difficulty is reduced, and the production efficiency is also improved.

[0101] In the above bracket 1, the specific type of the mounting structure is designed according to actual needs, for example, the mounting structure is a closed annular structure, or a ring structure with an opening. The above ring structure can be a circular ring or a square ring. In order to increase the contact area between the connecting rod 2 and the bracket 1 and improve stability, it is preferred that the mounting structure is a closed annular structure.

[0102] The first sub-frame body 101 and the second sub-frame body 102 are fixedly connected, and can be fixedly connected at the joint or at other positions. For the convenience of installation, it is preferred that the first sub-frame body 101 and the second sub-frame body 102 are fixedly connected at the joint. In this way, it is also convenient to fix the connecting rod 2 and the bracket 1.

[0103] Furthermore, the connecting rod 2, the first sub-frame body 101 and the second sub-frame body 102 are fixedly connected by the same connecting piece. In order to facilitate disassembly, the connecting rod 2, the first sub-frame body 101 and the second sub-frame body 102 are detachably fixedly connected by the same connecting piece. The connecting piece can be a threaded connecting piece, or a pin or other component, which is not limited in the embodiment of the present invention.

[0104] The first sub-frame 101 and the second sub-frame 102 can be fixedly connected by bonding, clamping, etc. In order to improve reliability, it is preferred that the first sub-frame 101 and the second sub-frame 102 are fixedly connected by a connector. The connector can be a threaded connector or a pin.

[0105] When the above-mentioned connecting piece is a threaded connecting piece, in order to improve the connection strength, the above-mentioned bracket also includes a gasket 107 used in conjunction with the threaded connecting piece. The first sub-frame body 101 is provided with a first mounting hole 1012 for accommodating the gasket 107, and the second sub-frame body 102 is provided with a second mounting hole 1013 for accommodating the gasket 107. The radius of the gasket 107 gradually changes along its axial direction. The first mounting hole 1012, the second mounting hole 1013 and the axis of the gasket 107 are staggered so that when the gasket 107 moves in the direction in which its radius decreases, the first sub-frame body 101 and the second sub-frame body 102 move toward each other.

[0106] The radius of the gasket 107 changes gradually along its axial direction, and the generatrix of the circumferential side surface of the gasket 107 can be a straight line inclined relative to the axis of the gasket 107, or can be an arc. When the generatrix of the circumferential side surface of the gasket 107 is a straight line inclined relative to the axis of the gasket 107, the gasket 107 is in a truncated cone shape, such as Figure 2 and Figure 3 The shapes of the first mounting hole 1012 and the second mounting hole 1013 are the same as those of the gasket 107. When the gasket 107 moves in the direction of decreasing radius, the circumferential side surface of the gasket 107 acts on the first sub-frame 101 and the second sub-frame 102, pushing the first sub-frame 101 and the second sub-frame 102 to move toward each other.

[0107] The axes of the first mounting hole 1012, the second mounting hole 1013 and the gasket 107 are staggered, so that there is a first gap between the gasket 107 and the hole wall of the first mounting hole 1012, and there is a second gap between the gasket 107 and the hole wall of the second mounting hole 1013. The first gap and the second gap are respectively located on both sides of the axis of the gasket 107, and the parts where the gasket 107 and the hole wall of the first mounting hole 1012 are attached, and the parts where the gasket 107 and the hole wall of the second mounting hole 1013 are attached are respectively located on both sides of the axis of the gasket 107. Figure 3 shown.

[0108] In the above structure, during the installation process, the gasket 107 moves in the direction of decreasing radius, so that the first sub-frame body 101 and the second sub-frame body 102 move toward each other, avoiding the separation of the first sub-frame body 101 and the second sub-frame body 102, making the connection between the first sub-frame body 101 and the second sub-frame body 102 more stable, thereby improving the connection strength.

[0109] Specifically, when the first sub-frame 101 and the second sub-frame 102 are fixedly connected by the bolt 1010 and the nut 108, it is preferred that the washer 107 and the nut 108 are located at the same end of the bolt 1010. Figure 3 shown.
