Description

Technical Field

[0001] The present invention relates to the technical field of water photovoltaics, and in particular to a floating water buoy array and an array unit. Background Art

[0002] Solar energy is a clean energy source. Using photovoltaic power stations to directly convert solar energy into electricity is a highly efficient way to utilize solar energy. Currently, photovoltaic power stations are primarily built on land, such as on unused land. However, due to the low energy distribution density and the significant impact of climatic conditions, land-based photovoltaic power stations typically require a large area. In economically developed regions, where land resources are scarce, the construction of photovoltaic power stations is significantly restricted. Floating photovoltaic power stations utilize unused water surfaces to build photovoltaic power stations. Floating photovoltaic power stations offer numerous advantages, such as not occupying land resources, reducing water evaporation, and preventing algae growth, and therefore hold great promise for development.

[0003] One implementation method for a floating photovoltaic power station is to use a floating photovoltaic array. Existing floating photovoltaic arrays all use fixed-angle, one-piece floats. Because the angle of sunlight varies across different regions, fixed-angle floats are difficult to adapt to multiple locations. Furthermore, as the specifications of solar panels change, one-piece floats are difficult to use with a variety of solar panels. Therefore, multiple mold openings can easily increase costs. Furthermore, because the floats must be installed in a specific orientation, the installation becomes more difficult, resulting in reduced construction efficiency. To improve construction efficiency, pre-installation is sometimes necessary. However, this method requires large-scale construction machinery and places certain requirements on the construction site.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings 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 making creative efforts shall fall within the scope of protection of the present invention.

[0035] In the detailed description that follows, reference may be made to the various drawings that form part of this application and illustrate specific embodiments of the present application. In the drawings, similar reference numerals describe substantially similar components in different figures. Each specific embodiment of the present application is described below in sufficient detail to enable a person of ordinary skill in the art to implement the technical solutions of the present application. It should be understood that other embodiments may be utilized or that structural, logical, or electrical changes may be made to the embodiments of the present application.

[0036] The present invention proposes a new type of floating array float suitable for water photovoltaic power stations. It has strong adaptability, high structural strength, convenient construction, and is suitable for large-scale construction and installation. The composed floating array can adapt to solar panels of various specifications.

[0037] Figure 1A-1G Schematic diagram of the main floating body according to one embodiment of the present application. Figure 1A-1D They are respectively the front view, right view, bottom view and rear view of the main floating body, showing the shapes of each surface of the main floating body. Figure 1E and Figure 1F This is a partial enlarged view of the main floating body, showing its specific shape. Figure 1G A three-dimensional view of the main floating body, showing its overall shape.

[0038] As shown in the figure, the main buoy 100 includes a main body 101. The upper surface of the main body 101 is substantially flat. The main body 101 includes one or more grooves 102 extending across the upper surface, dividing the upper surface into multiple sections. The grooves 102 are used to accommodate support brackets. The main body 101 is also provided with one or more lugs 103. According to one embodiment of the present application, the main buoy 100 is blow-molded.

[0039] According to one embodiment of the present application, the upper surface of the main body 101 is roughly rectangular. A pull ear 103 is provided at each corner of the main float. Each pull ear is used to connect to a connecting float. In some embodiments, the pull ear 103 includes a circular hole 104, which can be connected to the connecting float by bolts. In some embodiments, the pull ear 103 also includes a plurality of reinforcing ribs 105, which can be used to strengthen the strength of the pull ear, thereby ensuring the connection strength between the floats. In some embodiments, the pull ear 103 is integrally formed with the main float and extends outward from the main float. In some embodiments, the pull ear may also include a limiting device (not shown in the figure). For example: the circular hole 104 includes an outwardly protruding portion, and the bolt also includes a similar protruding portion. When the bolt is inserted into the circular hole 104, the protruding portion of the bolt falls into the outwardly protruding portion of the circular hole 104, thereby acting as a bolt limiter.

[0040] refer to Figure 1E According to one embodiment of the present application, the reinforcing rib 105 includes a reinforcing ring 1051 and multiple transverse reinforcing strips 1052. The reinforcing ring 1501 is positioned between the circular hole 104 and the edge of the tab, while the multiple transverse reinforcing strips 1502 are positioned between the circular hole 104 and the reinforcing ring 1501 and / or between the edge of the tab and the reinforcing ring 1501. In some embodiments, at the reinforcing ring 1501, the transverse reinforcing strips connected to the circular hole 104 and the transverse reinforcing strips connected to the edge of the tab do not overlap, preventing the formation of a "cross" cross section, which would result in material stacking, excessive material demand, waste, and the creation of holes. Staggering the transverse reinforcing strips connected to the circular hole 104 and the transverse reinforcing strips connected to the edge of the tab at the reinforcing ring also facilitates tab fabrication.

[0041] According to one embodiment of the present application, the pull tabs may also include an information area 106 that can be used to display specific information about the pull tabs. In some embodiments, information area 106 may use different numbers to indicate the distance of the pull tabs from the top surface of the main float. This allows pull tabs of different heights to be combined to help maintain the float array on the same horizontal plane. In some embodiments, information area 106 may also use different numbers to indicate the different strengths of the pull tabs. This allows different numbers of pull tabs to be connected when assembling the float array, thus maintaining consistent connection strength across the float array.

[0042] In some embodiments, each side of the main float may further include a plurality of through or non-through recesses 120 to improve the rigidity of the main float, increase the load-bearing capacity of the upper surface of the float, and increase the ability of the float to resist deformation under stress.

[0043] According to one embodiment of the present application, a plurality of grooves 102 are provided on the main floating body, and the grooves 102 are used to accommodate the support frames supporting the solar cell modules. In some embodiments, the grooves 102 are provided on the upper surface of the main floating body and pass through the opposite ends of the upper surface.

[0044] According to one embodiment of the present application, the groove 102 includes one or more connecting portions 107, which are used to fix and connect the support frame supporting the solar cell assembly. The support frame is set in the groove 102 and fixed to the connecting portion 107, thereby supporting and fixing the solar cell panel. Figure 1F For example, the connection portion 107 can be a sheet material disposed at each end of the groove and include one or more through-holes 108. Bolts pass through the through-holes 108 and secure the support frame to the main buoy. As those skilled in the art will appreciate, the support frame and the main buoy can be connected by other means, such as riveting, welding, or providing a base similar to the connection portion 107 on the support frame that can be directly snapped into the groove 102.

[0045] In some embodiments, the outside of the groove may further include one or more fixing members, which are configured to fix the support frame accommodated in the groove. For example, the outside of the groove includes one or more clamps, and the support frame can be fixed in the groove by locking the clamps. In some embodiments, the groove may include one or more bends, and the support frame can be made into a bent shape so that it can be accommodated in the groove and can be fixed with the groove. In some embodiments, the bend can be perpendicular to the upper surface of the main body or parallel to the upper surface of the main body. In some embodiments, the shape of the bend can be V-shaped, arc-shaped, S-shaped, etc. As shown in the figure, the number of grooves is 3, dividing the upper surface of the main body into 4 parts. In some embodiments, the number of grooves can also be more than 3, which is conducive to the support frame being set in different grooves to be suitable for solar panels of different specifications. In some embodiments, the number of grooves can also be less than 3.

[0046] According to one embodiment of the present application, the main buoy 100 may further include a boss 109, disposed on the connection portion 107 and located between the connection portion 107 and the support frame. This boss 109 can enhance the wear resistance of the connection portion 107, thereby preventing the support frame from abrading the connection portion 107 and thereby damaging the buoy. In some embodiments, the height of the boss 109 may be 2 mm to 5 mm.

[0047] According to one embodiment of the present application, the upper and lower side surfaces of the main float may further include a plurality of recesses 110, and the connection portion 107 is accommodated in the recess 110 to enhance the strength between the main float and the support frame, and to protect the connection between the main float and the support frame. Moreover, when multiple floats form a float array, the recess 110 can provide a connection installation operation space between the floats, or a connection installation operation space between the support frame and the float. In some embodiments, the connection portion 107 can be integrally formed with the groove 102, and the connection portion 107 can also be integrally formed with the recess 110. The recess 110 is located on the side of the main float, which is more conducive to reducing the area of ​​the main float, saving the material of the float, and reducing the production cost of the float.

[0048] The strength of the main float and the firm connection between the main float and the connecting float have a significant impact on the stability of the photovoltaic array. The main float of the present invention has made many improvements in materials and structure to improve the strength of the main float and the firmness of the connection with the connecting float.

[0049] According to one embodiment of the present application, the main float is made of high-density polyethylene material with high strength, good toughness and durability. Furthermore, the main float includes one or more reinforcement holes, which are arranged on the center line of the main float. In other embodiments, the reinforcement holes can also be arranged on the diagonals of the main float. According to one embodiment of the present application, the main float is provided with two reinforcement holes 111 and 112, the area of ​​the reinforcement holes is less than 1 / 50, 1 / 80, and 1 / 100 of the upper surface of the main body, and is arranged on the center line of the main float where multiple grooves divide different parts. As shown in the figure, the groove 102 divides the main float into 4 parts, and the reinforcement holes 111 and 112 are respectively arranged on the two larger parts of the main float in the middle. The presence of the reinforcement holes can provide additional support points when people walk after the main float is launched into the water, reduce its deformation, increase the stability of the main float in the water, and at the same time increase the rigidity of the main float.

[0050] According to one embodiment of the present application, mesh concave lines with different patterns are provided on the upper and lower surfaces of the main float, respectively. The mesh concave lines can increase the strength of the main float and its ability to resist external forces, and can also increase a certain degree of anti-slip properties. According to one embodiment of the present application, the patterns on the upper and lower surfaces are different, so that the main float can resist external forces in different directions, which is more conducive to improving the strength of the main float. According to one embodiment of the present application, mesh concave lines 113 perpendicular to each other are provided on the upper surface at 45 degrees and 135 degrees, and mesh concave lines 114 perpendicular to each other are provided on the lower surface at 0 degrees and 90 degrees.

[0051] In some embodiments, the mesh grooves 113 on the upper surface are more prominent relative to the upper surface of the main float, which is beneficial to increase the friction of the upper surface of the main float and increase the beauty of the main float. At the same time, it is also beneficial to strengthen the flow of water from the holes to the outside of the main float, or to facilitate the discharge of external rainfall, mud and sand to the outside of the main float, avoiding the increase in the gravity of the main float due to the water, mud and sand stored in the mesh grooves 113, thereby reducing the buoyancy of the main float.

[0052] According to one embodiment of the present application, the junction between the lower surface and the side surface of the main float is an inclined surface. This facilitates the dispersion of material across the float during blow molding, improving material utilization and avoiding material concentration at the junction between the lower surface and the side surface, which would otherwise waste material. This localized material concentration would also cause excessive stretching in other areas, resulting in poor quality and a lower yield rate. Furthermore, when the lower surface of the float contacts the water surface, it also disperses wave impact forces, thereby dispersing the stress exerted by the water surface, avoiding stress concentration and preventing rupture of the float.

[0053] According to one embodiment of the present application, the main float can be hollow inside. The hollow float can reduce material consumption and increase the buoyancy of the float. At the same time, it also has certain benefits in resisting stress and deformation under stress.

[0054] According to one embodiment of the present application, the main float may further include a vent valve 115, which is arranged between the two pull ears and is used for the internal and external gas circulation of the float to prevent damage to the float caused by thermal expansion and contraction. As understood by those skilled in the art, the vent valve can be set at any position of the main float. The opening of the vent valve 115 may also include a valve, which is used to prevent liquid from entering the interior of the float and affecting the buoyancy of the float. According to one embodiment of the present invention, the valve can be made of polytetrafluoroethylene, and the protection level can be IP65 or above, which can allow gas to pass through and prevent liquid from passing through.

Figure 2A-2D They are respectively the front view, right view, bottom view and rear view of the connecting floating body, showing the shapes of each surface of the connecting floating body. Figure 2E It is a three-dimensional diagram of the connected floating body, showing its overall shape.

[0056] As shown in the figure, the connecting float 200 includes a main body 210. The upper surface of the main body 210 is a rectangle with longer long sides, and the upper surface of the main body 210 is basically flat. Among them, one or more pull ears 201 are provided on the main body 210. According to one embodiment of the present application, the connecting float 200 includes multiple pull ears, which are provided on the corners of the connecting float and on the two longer sides and extend outward. As shown in the figure, the pull ear is provided in the middle of the longer side, and the middle pull ear cooperates with the pull ears on the corners to simultaneously connect the two main floats. According to one embodiment of the present application, the pull ear 201 is similar to the main float pull ear 103, so it will not be repeated here. In some embodiments, the connecting float is made by blow molding.

[0057] According to one embodiment of the present application, each side surface of the connecting float 200 includes multiple through or non-through grooves 202, which can be used to increase the rigidity of the main body itself, increase the bearing load on the upper surface of the float, and increase the ability of the float to resist deformation under force.

[0058] The strength of the connecting float and the firm connection between the connecting float and the main float have a significant impact on the stability of the photovoltaic array. The connecting float of the present invention has made many improvements in materials and structure to improve its strength and the firmness of its connection with the main float.

[0059] According to one embodiment of the present application, the connecting float is made of high-density polyethylene material with high strength, good toughness and durability. Furthermore, a non-through opening 203 is provided on the lower surface of the connecting float, and the presence of the opening 203 is also to increase the rigidity of the connecting float. According to one embodiment of the present application, the opening is a strip opening along the direction of the connecting float, and gradually shrinks from the lower surface to the upper surface in a stepped shape. The strip opening at the bottom of the connecting float also has certain benefits in resisting stress, and can also provide additional support points when people walk, thereby improving the overall bending resistance of the float.

[0060] According to one embodiment of the present application, the upper surface of the connecting float may include one or more reinforcement holes, which are arranged on the center line of the connecting float. In other embodiments, the reinforcement holes may also be arranged on the diagonal lines of the connecting float. According to one embodiment of the present application, the connecting float is provided with two reinforcement holes 204 and 205, the areas of the reinforcement holes are smaller than 1 / 50, 1 / 80, and 1 / 100 of the upper surface of the main body, and are connected to the opening of the lower surface. As shown in the figure, the reinforcement holes 204 and 205 divide the connecting float into three parts. The presence of the reinforcement holes can provide additional support points when people walk after the connecting float is launched into the water, thereby reducing its deformation, increasing the stability of the connecting float in the water, and at the same time increasing the rigidity of the connecting float.

[0061] According to one embodiment of the present application, mesh grooves with different patterns are provided on the upper and lower surfaces of the connecting float. The mesh grooves can increase the strength of the connecting float and its ability to resist external forces, and can also have a certain degree of anti-slip properties. According to one embodiment of the present application, the patterns on the upper and lower surfaces are different, so that the connecting float can resist external forces in different directions, which is more conducive to improving the strength of the connecting float. According to one embodiment of the present application, mesh grooves 206 are provided on the upper surface at 45 degrees and 135 degrees perpendicular to each other, and mesh grooves 207 are provided on the lower surface at 0 degrees and 90 degrees perpendicular to each other.

[0062] In some embodiments, the mesh grooves 206 on the upper surface are more prominent relative to the upper surface of the connecting float, which is beneficial to increasing the friction of the upper surface of the connecting float and increasing the beauty of the connecting float. At the same time, it is also beneficial to enhance the flow of water from the holes to the outside of the connecting float, or to facilitate the discharge of external rainfall, mud and sand to the outside of the connecting float, avoiding the increase in the gravity of the connecting float due to the water, mud and sand stored in the mesh grooves 206, thereby reducing the buoyancy of the connecting float.

[0063] According to one embodiment of the present application, the connection between the lower surface and the side surface of the float is an inclined surface. This facilitates the dispersion of material across the float during blow molding, improving material utilization and avoiding material concentration at the connection between the lower surface and the side surface, which can waste material. This localized material concentration can also cause excessive stretching in other areas, resulting in poor quality and reduced yield. Furthermore, when the lower surface of the float contacts the water surface, it can disperse wave impact forces, thereby dispersing the stress exerted by the water surface, avoiding stress concentration and preventing rupture of the float.

[0064] According to one embodiment of the present application, the connecting float can be hollow inside. The hollow float can reduce material consumption and increase the buoyancy of the float. At the same time, it also has certain benefits in resisting stress and deformation under stress.

[0065] According to one embodiment of the present application, the connecting float may further include a vent valve 208, which is disposed between the two pull ears and is used for the internal and external gas circulation of the float to prevent damage to the float caused by thermal expansion and contraction. As understood by those skilled in the art, the vent valve can be disposed at any position of the connecting float. The opening of the vent valve 208 may further include a valve, which is used to prevent liquid from entering the interior of the float and affecting the buoyancy of the float. According to one embodiment of the present invention, the valve can be made of polytetrafluoroethylene, and the protection level can be IP65 or above, which can allow gas to pass through and prevent liquid from passing through.

According to one embodiment of the present application, the lugs 301 are disposed at each corner of the connecting float 300. As shown, any two lugs of the connecting float 300 can be connected to the main float 100 and / or the connecting float 200. According to one embodiment of the present application, the lugs 301 are similar to the main float lugs 103 and are not described in detail here. In some embodiments, the connecting float 300 is blow-molded.

[0068] According to one embodiment of the present application, each side surface of the connecting float 300 includes a through or non-through groove 302, which can be used to increase the rigidity of the main body itself, increase the bearing load on the upper surface of the float, and increase the ability of the float to resist deformation under force.

According to one embodiment of the present application, the floating array unit 400 also includes a second support frame 420, which is arranged in the grooves of the plurality of spaced main floating bodies 100 and is fixedly connected to the plurality of main floating bodies, and can be used to carry solar cell modules. As understood by those skilled in the art, the first support frame 410 and / or the second support frame 420 are arranged in different grooves of the main floating body 100, and can carry solar cell modules of different specifications, thereby increasing the scope of application of the floating array.

[0078] According to one embodiment of the present application, the floating body array unit 400 includes three main floating bodies 100, four connecting floating bodies 200, and two connecting floating bodies 300. Among them, the first support frame 410 and the second support frame 420 are set on the three main floating bodies 100, the main floating bodies at both ends of the first support frame 410 and / or the second support frame 420 are connected to the connecting floating bodies 200, and the main floating body in the middle of the first support frame 410 and / or the second support frame 420 is connected to the connecting floating body 300. In some embodiments, multiple floating body array units are connected to each other to form a floating body array (refer to Figure 6 ), install the connecting bracket on the first support frame 410 and / or the second support frame 420 (refer to Figure 5 ), and install solar panels on the bracket to form a photovoltaic array.

[0079] According to one embodiment of the present application, the floating array unit 400 may also include other numbers of main floats. For example, one more main float is provided on the outside of each end of the first support frame 410 and / or the second support frame 420, which is connected to the main floats supporting both ends and the connecting float 200. According to another embodiment of the present application, the connecting float 200 may also be shared by the two floating array units, that is, the connecting float 200 connects the main floats of the two floating array units, thereby facilitating the overall strength of the floating array and avoiding the influence of multiple connection points on the overall strength of the floating array. According to another embodiment of the present application, the floating array unit 400 may also only include the main float 100 and the first support frame 410 and the second support frame 420. When forming a floating array, multiple floating array units are connected by connecting the float 200 and the connecting float 300 to form a floating array.

[0080] As those skilled in the art will appreciate, in a photovoltaic array, some electrical equipment also needs to be configured, and in the later maintenance of the photovoltaic array, only maintenance personnel need to pass through. Therefore, in a photovoltaic array, a central channel can be formed by connecting multiple main floats 100 side by side, which can be used to carry electrical equipment. The main floats between the first support frame 410 and / or the second support frame 420 are connected by a connecting float 300, providing a maintenance channel for maintenance personnel. This arrangement can serve as a reminder, and adopting this arrangement saves the use of float materials and reduces the construction cost of the photovoltaic power station. In some embodiments, the central channel can also be formed by multiple connecting floats 200. In some embodiments, the multiple main floats of the central channel can be connected by support frames 410 and support frames 420, or by using bolts to connect the main floats' own lugs. In some embodiments, the float array can also include an edge, which can be formed by connecting multiple connecting floats 200 or multiple main floats 100.

[0081] According to one embodiment of the present application, the first support frame 410 and the second support frame 420 can be used to install solar panels, which can be purlins. By setting the purlins in the grooves of the main floating body 100 and fixedly connecting them to the main floating body, the solar panel brackets are installed on the purlins. According to one embodiment of the present application, the first support frame 410 and the second support frame 420 can include brackets for fixing solar panels, and the solar panels can be directly installed on the brackets. According to one embodiment of the present application, the first support frame and the second support frame include bracket fixing assemblies, which can enable the first support frame and the second support frame to be installed at multiple positions to fix the brackets of the solar panel.

[0082] According to one embodiment of the present application, the first support frame 410 and the second support frame 420 may be angle steel with a U-shaped cross-section, or square tubes. In some embodiments, depending on the specifications of the solar cell modules or the location of the photovoltaic array, mounting holes may be machined at appropriate locations on the first support frame 410 and the second support frame 420 to allow for mounting brackets and further support the solar cell modules, thereby further expanding the applicability of the floating array.

[0083] refer to Figure 4CAccording to another embodiment of the present application, the first support frame 410 and the second support frame 420 may be profiles with T-slots on the surface. In some embodiments, depending on the specifications of the solar cell modules, or the region where the photovoltaic array is located, the bracket can be installed at any position of the first support frame 410 and / or the second support frame 420 using T-bolts, so as to support the solar cell modules, and the purlins and the main float can also be directly fixed and connected using T-bolts. This avoids the step of on-site machining of mounting holes, which is convenient and quick. In some embodiments, the bracket fixing assembly can be a hole or T-slot machined on the first support frame 410 and the second support frame 420.

[0084] In some embodiments, the floating array unit may also include a reinforcement bar (not shown in the figure), which is arranged between the first support frame 410 and the second support frame 420, and is used to increase the strength of the mounting holes processed at appropriate positions on the first support frame 410 and the second support frame 420, and improve the bearing capacity of the mounting holes processed at appropriate positions on the first support frame 410 and the second support frame 420.

Specifically, the bracket body 701 includes an upper portion 703, a middle portion 704, and a lower portion 705. The lower portion 705 is fixedly connected to the support frame and includes a connection hole 706, which can be fixedly connected to the support frame via bolts. The upper portion 703 is connected to the clamping portion 702, which includes a connection hole 707 and can be fixedly connected to the clamping portion via a connector 708. The upper portion 703 is parallel to the lower portion 705, which allows the clamping portion to be parallel to the support frame, facilitating the installation of the solar panel. According to one embodiment of the present application, the connector 708 can be a bolt, which can be used to connect the clamping portion 702 and the bracket body, greatly improving the installation speed.

[0087] In some embodiments, the middle portion 704 is not perpendicular to the upper portion 703 and / or the lower portion 705, which can increase the distance between the clamping portions of a set of long brackets, thereby accommodating solar panels of different specifications. According to one embodiment of the present application, the middle portion 704 can also include one or more reinforcement strips 709, which can be used to increase the strength of the bracket body and improve the bracket's load-bearing capacity.

[0088] According to one embodiment of the present application, the clamping portion 702 includes a pressing member 711 and a locking member 712. The pressing member 711 includes a pressing member body 713 and a blocking piece 714 connected to the pressing member body, wherein the pressing member body is a U-shaped groove, the size of which is the same as the size of the upper part of the bracket body, which can be used to accommodate the locking member 712, and the blocking piece 714 is used to contact and press the metal frame of the solar cell panel. According to one embodiment of the present application, the blocking piece 714 has a certain curvature, which can press the solar cell panel and increase the pre-tightening force between the solar cell and the metal frame. According to one embodiment of the present application, the blocking piece 714 is connected to both ends of one side of the pressing member body 713, which can increase the strength of the blocking piece. According to one embodiment of the present application, the pressing member body includes a connecting hole 715, which is arranged at the center of the pressing member body and is opposite to the connecting hole 707 of the upper part of the bracket body, and can be connected through a connecting piece 708.

[0089] According to one embodiment of the present application, the locking member 712 includes a locking member body 716 having a cross-section similar to a hollow rectangle, and a first hook 717 extending outward from a corner of the locking member body at a certain angle and bent at the end to form a hem, which is used to hook the metal frame of the solar cell panel. The size of the locking member body 716 is equal to that of the pressing member body 713, and it can be accommodated in the pressing member body 713. The locking member body also includes a fixing hole 718, which is located at the center of the locking member body and runs through two opposite surfaces of the entire locking member body, and can be connected to the bracket body and / or the pressing member body through the connecting member 708. In some embodiments, the size of the locking member body 716 can be smaller than that of the pressing member body 713. For example, the nut of the connecting member 708 can be placed inside the locking member body 716, and the locking member body 716 can clamp the nut, making it easier to install the bracket.

[0090] According to one embodiment of the present application, the contact area between the hook side of the locking member body 716 and the pressing member body includes a ridge 719, which can separate the locking member body from the pressing member body. When the connector 708 connects the locking member body and the pressing member body, a torque can be generated, causing the hook 718 to tilt toward the blocking piece 714, further clamping the solar panel. As understood by those skilled in the art, the tighter the connector 708 connects the locking member body and the pressing member body, the tighter the hook 718 and the blocking piece 714 clamp the solar panel. According to one embodiment of the present application, the connector 708 can be a bolt, and the pressing member 711, the locking member 712 and the bracket body can be connected by the same bolt, which can greatly improve the construction speed.

[0091] According to one embodiment of the present application, the short bracket 720 includes a base plate 721 and a clamping portion 722. The base plate 721 can be used to connect to the support frame, and includes an opening 723, which can be connected to the support frame by bolts. The clamping portion 722 includes a clamping portion body 724 connected to the base plate, a second hook 725 extending outward from the clamping portion body, and a stop portion 726. The hook 725 can be used to hook the metal frame of the solar panel, and the stop portion 726 is used to contact the side of the solar panel and stop the solar panel. According to one embodiment of the present application, the clamping portion body is n-shaped. According to one embodiment of the present application, the short bracket 720 may also include a receiving portion 727, which is arranged on the base plate and surrounds the opening 723, and can be used to accommodate connecting bolts. According to one embodiment of the present application, the receiving portion 727 may be two L-shaped connecting plates, which form a T-shaped groove with the base plate. According to one embodiment of the present application, the bracket is a standard aluminum alloy part.

The solar panel is then first hooked to the bottom of the metal frame of the solar panel through the second curved hook 724 of the short support 702, while the stop portion 726 of the short support is blocked against the side of the metal frame of the solar panel. The first curved hook 717 of the locking member of the long support is then hooked to the top of the metal frame of the solar panel, and the pressing member of the long support is blocked against the side of the metal frame of the solar panel. The locking member is then placed into the pressing member. The locking member, pressing member, and support body of the long support are connected through the connecting member, and the connecting member is locked to achieve the connection between the support and the solar panel. According to one embodiment of the present application, the stop portion 726 of the short bracket and the blocking piece 714 of the long bracket pressing member both have a certain curvature, which will produce elastic deformation with a certain displacement when blocking the solar panel, and can smoothly guide the solar panel into between the stop portion and the second hook, as well as between the locking member and the pressing member, thereby increasing the firmness of the solar panel after installation.

[0093] According to one embodiment of the present application, long brackets 710 and short brackets 720 provide support for solar panels, achieving a certain degree of tilt. One end of each bracket is mounted to a support frame, which is then mounted to multiple main buoys.
