Description

Technical field

[0001] The utility model belongs to the field of photovoltaic technology, and specifically relates to photovoltaic installation technology. [Background Technology]

[0002] At present, photovoltaic modules are mainly installed on the roof, and mounting brackets are set on the roof. The installation technology of conventional roof mounting brackets is mature, but the wall photovoltaic installation method is basically blank. When installing photovoltaic modules on the wall of a house, conventional medium-voltage block structures are often used for fixation. With reference to the Chinese utility model patent with announcement number CN215934792U, a wall photovoltaic module is disclosed, including a frame, symmetrically arranged fixing rods are symmetrically arranged on the rear side of the frame, and a limiting seat is arranged between the symmetrically arranged frames. A movable block is fixed to the bottom end of the limiting seat, and a movable groove is provided on the surface of the fixing rod, and a clamping block is symmetrically fixed on the inner side of the movable groove. The bottom end of the movable block is symmetrically provided with a clamping groove, and a connecting plate is provided on the inner side of the clamping groove. A connecting spring is connected between the connecting plate and the clamping block, and mounting holes are provided on the inner side of the limiting seat and the fixing rod. Conventional clamping structures require wall bracket installation before attaching and securing the conventional clamping components. This cumbersome installation method lacks stability, and requires multiple people to coordinate lifting the components before securing them. This results in low construction efficiency and high costs. After installation, conventional clamping blocks protrude from the component frame, creating large gaps between components and poor aesthetics. They are also susceptible to corrosion from prolonged exposure to wind and sun, posing safety risks and increasing maintenance costs. [Utility Model Content]

[0003] In view of the deficiencies of the existing technology, the technical problem to be solved by the present invention is to provide a photovoltaic component fixing part and a photovoltaic system installed on a fixed plane, so as to solve the problems of cumbersome installation and low installation efficiency of the conventional pressing block installation method in the existing technology.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] First, a photovoltaic component fixing device installed on a fixed plane is provided, which is used to fix a first photovoltaic component and a second photovoltaic component arranged side by side on the fixed plane. The photovoltaic component fixing device includes a plane fixing seat and a first component and a second component movably connected to the plane fixing seat; the plane fixing seat is installed on the fixed plane, the first component is provided with a first connecting portion connected to the first photovoltaic component on a first side of the plane fixing seat, and the second component is provided with a second connecting portion connected to the second photovoltaic component on a second side of the plane fixing seat.

[0006] Preferably, the planar fixing seat includes a plug-in portion and a planar portion connected to the fixing plane, the extension direction of the plug-in portion is parallel to the side frames connecting the first photovoltaic component and the second photovoltaic component, and the first component and the second component are plugged into the plug-in portion in sequence along the extension direction of the plug-in portion.

[0007] Preferably, the plane portion is L-shaped, including a first side and a second side connected vertically, and the first side fits the fixed plane, and the second side is connected to the plug-in portion.

[0008] Preferably, the length direction of the planar portion is perpendicular to the length direction of the plug-in portion, and the length of the planar portion is greater than the width of the plug-in portion. The planar portion is provided with a planar fixing hole on both sides of the length.

[0009] Preferably, the first component is provided with a first socket, and the second component is provided with a second socket. The first socket and the second socket are plugged into the plug-in portion side by side along the extension direction of the plug-in portion. The first connecting portion is provided on the first side of the first socket, and the second connecting portion is provided on the second side of the second socket.

[0010] Preferably, the first socket is connected to one end of the first connecting portion, the first socket is shorter than the other end of the first connecting portion and forms a first notch, and the second socket is matched with the first notch.

[0011] Preferably, the first connecting portion is provided with a first connecting plane parallel to the fixing plane, and the first connecting plane is provided with a first connecting hole; the second connecting portion is provided with a second connecting plane parallel to the fixing plane, and the second connecting plane is provided with a second connecting hole.

[0012] Preferably, the plug-in portion is provided with a plurality of cavities; and / or the side walls of the first plug hole and the second plug hole are provided with a plurality of cavities.

[0013] Preferably, the planar fixing seat and / or the first component and / or the second component are profiles; and / or the planar fixing seat and / or the first component and / or the second component are made of aluminum alloy or stainless steel.

[0014] In addition, a photovoltaic system is provided, comprising a first photovoltaic assembly and a second photovoltaic assembly arranged side by side, and also comprising the photovoltaic assembly fixing member, wherein the photovoltaic assembly fixing member mounts the first photovoltaic assembly and the second photovoltaic assembly on a fixed plane.

[0015] The utility model adopts the above technical solution, which has the following beneficial effects:

[0016] 1. The entire photovoltaic module fixture includes a flat mounting base, a first component, and a second component. These three components are split structural parts. The flat mounting base is installed on the fixed plane. The first and second components are assembled with the flat mounting base in an inlay (movable plug-in) combination. Finally, the adjacent first and second photovoltaic modules are connected to the first and second components respectively. Because the split components of the photovoltaic module fixture use an inlay (movable plug-in) combination, there is no need for additional fasteners. This not only facilitates construction but also makes subsequent operation and maintenance more convenient. The first and second components can be easily separated from the flat mounting base, thereby improving construction and operation efficiency and reducing the cost of subsequent operation and maintenance.

[0017] In addition, the first connecting portion is provided on the first side of the planar mounting base and is connected to the first photovoltaic module, while the second connecting portion is provided on the second side of the planar mounting base and is connected to the second photovoltaic module. Thus, a single photovoltaic module mounting member can simultaneously secure two adjacent photovoltaic modules, making it convenient to secure multiple photovoltaic modules side by side to form a photovoltaic array. Furthermore, compared to conventional press block mounting structures in the prior art, the number of components is relatively reduced, thereby reducing costs.

[0018] 2. The planar portion is connected to the fixed plane. Since the plug-in portion extends in a direction parallel to the side frames where the first and second photovoltaic modules meet, and the first and second components are sequentially plugged into the plug-in portion along the direction in which the plug-in portion extends, the three components, the planar fixing base, the first component, and the second component, can be compactly integrated. Since the first and second components are sequentially plugged into the plug-in portion along the direction in which the plug-in portion extends, the space occupied by the plug-in portion of the first and second components in the lateral direction can be reduced, which helps to reduce the gap between the first and second photovoltaic modules.

[0019] 3. The plane portion is an L-shaped structure. Taking fixing to a wall as an example, the first side can be fixed in contact with the fixing plane, and the second side can make the plug-in portion a certain distance away from the wall. In this way, after the first side is fixed to the wall, the first socket and the second socket have a gap relative to the wall, and can be flexibly plugged in relative to the plug-in portion, and the second side supports the first socket.

[0020] 4. The length direction of the planar portion is perpendicular to the length direction of the plug-in portion, and the length of the planar portion is greater than the width of the plug-in portion. In this way, the planar portion and the plug-in portion form a T-shaped structure as a whole. Since it is installed on the wall, the planar portion is set at the bottom, and the length direction of the planar portion is parallel to the horizontal plane. Therefore, the upward extension direction of the plug-in portion is mainly utilized to achieve the first and second sockets being plugged into the plug-in portion in sequence along the extension direction of the plug-in portion, wherein the planar portion supports the first socket, and the first socket supports the second socket. Since the first connecting portion is set on the first side of the first socket and the second connecting portion is set on the second side of the second socket, the first connecting portion and the second connecting portion are correspondingly located on the first and second sides of the fixing member. In this way, the height of the first socket and the second socket protruding from the wall can be kept consistent, and the lateral occupied space will not be increased. Therefore, when the fixing member is used to install the photovoltaic module, it is helpful to narrow the gap between two adjacent photovoltaic modules in the horizontal direction.

[0021] In addition, the design adopts two flat fixing holes on both sides, which are fixed to the wall through bolts, rivets or other fasteners. The double-hole fixation is more stable.

[0022] 5. The second socket cooperates with the first notch to form a reverse cross-staggered design of the first component and the second component. The clever thing is that the first socket and the second socket are sequentially plugged into the plug-in portion of the plane fixing seat along the extension direction of the plug-in portion, and can fit with the plane portion below. The three form a whole, and the structure is more stable. In addition, the upper end surfaces of the first component and the second component are flush, which not only ensures safety and stability, but also ensures that the components on both sides are kept on the same horizontal line, and the overall effect is more beautiful after installation.

[0023] 6. The first connection plane and the second connection plane are located on the back of the photovoltaic module frame, and do not occupy the gap width space between the first photovoltaic module and the second photovoltaic module, which is conducive to narrowing the gap; and compared with conventional pressing blocks, the first connection hole and the second connection hole are fixed to the mounting holes on the back of the photovoltaic module frame, cleverly utilizing the photovoltaic module itself to shield the structural parts from sun exposure and rain erosion, avoiding rust on the connection parts, thereby achieving better quality and longer service life.

[0024] 7. The separate components of the photovoltaic module fixing parts can adopt a hollow design, that is, a certain number of cavities are added, which reduces the material cost, is lighter, and is convenient for construction.

[0025] 8. The individual components of photovoltaic module mounting brackets can be made of aluminum alloy or stainless steel, extending their service life (up to 25 years) and ensuring a single installation for full lifecycle functionality. Furthermore, the color of the mounting brackets matches the panel frame, creating a more harmonious and aesthetically pleasing design. Furthermore, they can be mass-produced, for example, using die stamping, to reduce costs.

[0026] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0039] Reference Figures 1 to 5 As shown, in this embodiment, a photovoltaic module fixture is mounted on a fixed surface. The fixed surface can be a wall, so the wall installation is used as an example for description. The fixture includes a planar mounting base 1 mounted on the fixed surface, and a first component 2 and a second component 3 that are movably connected to the planar mounting base 1. The first component 2 has a first connection portion on a first side of the planar mounting base 1 that connects to the first photovoltaic module, and the second component 3 has a second connection portion on a second side of the planar mounting base 1 that connects to the second photovoltaic module. The first side and the second side refer to the opposite sides of the photovoltaic module fixture corresponding to the connection between the first photovoltaic module and the second photovoltaic module, i.e., the left and right sides.

[0040] The entire photovoltaic module fixture includes a planar fixing base, a first component, and a second component. These three components are split structural members, with the planar fixing base mounted on a fixed plane. The first and second components are assembled with the planar fixing base in an inlay (movable plug-in) combination. Finally, the adjacent first and second photovoltaic modules are connected to the first and second components, respectively. Because the split components of the photovoltaic module fixture use an inlay (movable plug-in) combination, there is no need for additional fasteners, making construction easier and subsequent operation and maintenance more convenient. The first and second components can be easily separated from the planar fixing base, thereby improving construction and operation efficiency and reducing the cost of subsequent operation and maintenance.

[0041] In addition, the first connecting portion is provided on the first side of the planar mounting base and is connected to the first photovoltaic module, while the second connecting portion is provided on the second side of the planar mounting base and is connected to the second photovoltaic module. Thus, a single photovoltaic module mounting member can simultaneously secure two adjacent photovoltaic modules, making it convenient to secure multiple photovoltaic modules side by side to form a photovoltaic array. Furthermore, compared to conventional press block mounting structures in the prior art, the number of components is relatively reduced, thereby reducing costs.

[0042] In this embodiment, the plane fixing seat 1 is provided with a plane portion 11 connected to the fixing plane and a plug-in portion 12 plugged into the first component 2 and the second component 3. The extension direction of the plug-in portion 12 is parallel to the side frame of the first photovoltaic assembly and the second photovoltaic assembly, that is, the vertical direction. The first component 2 and the second component 3 are sequentially plugged into the plug-in portion along the extension direction of the plug-in portion and supported from below by the plane fixing seat 1, so that the three components of the plane fixing seat, the first component and the second component are compactly and reliably combined into one. In this way, after the first component and the second component are connected to the assembly, they abut against each other under the action of gravity and can be stably fixed. Since the first component and the second component are sequentially plugged into the plug-in portion along the extension direction of the plug-in portion, the space occupied by the plug-in portion of the first component and the second component in the lateral width direction can be reduced, which is conducive to reducing the gap between the first photovoltaic assembly and the second photovoltaic assembly.

[0043] The planar portion 11 is L-shaped, including a first side 111 and a second side 112 connected vertically, the first side being in contact with the fixed plane, and the second side being connected to the plug-in portion. The length direction of the planar portion 11 is perpendicular to the length direction of the plug-in portion 12, and the length of the planar portion is greater than the width of the plug-in portion. The planar portion is provided with a planar fixing hole 113 on both sides of the length. The first component is provided with a first plug-in hole 22, and the second component is provided with a second plug-in hole 31. The first plug-in hole 22 and the second plug-in hole 31 are sequentially plugged into the plug-in portion along the extension direction of the plug-in portion. The first connecting portion is provided on the first side of the first plug-in hole 22, and the second connecting portion is provided on the second side of the second plug-in hole 31. The plug-in portion 12 is a rectangular cylinder, and the first plug-in hole 22 and the second plug-in hole 31 are rectangular holes.

[0044] In the above technical solution, the length direction of the planar portion is perpendicular to the length direction of the plug-in portion and the length of the planar portion is greater than the width of the plug-in portion, so that the planar portion and the plug-in portion form an overall T-shaped structure. Since it is installed on the wall, the planar portion is set at the bottom, and the length direction of the planar portion is parallel to the horizontal plane. Therefore, the upward extension direction of the plug-in portion is mainly utilized to realize the first socket and the second socket being plugged into the plug-in portion in sequence along the extension direction of the plug-in portion. In this way, the height of the first socket and the second socket protruding from the wall can be kept consistent, and the horizontal occupied space will not be increased, so that when the photovoltaic components are installed using the fixing member, it is beneficial to narrow the gap between two adjacent photovoltaic components in the horizontal direction.

[0045] In addition, the flat portion supports the first insertion hole, and the first insertion hole supports the second insertion hole. Since the first connecting portion is arranged on the first side of the first insertion hole and the second connecting portion is arranged on the second side of the second insertion hole, the first connecting portion and the second connecting portion are respectively located on the first side and the second side of the fixing member.

[0046] In the L-shaped structure of the plane portion 11, the first side can be fixed in contact with the fixed plane, while the second side can keep the plug-in portion a certain distance away from the wall. In this way, after the first side is fixed to the wall, the first socket and the second socket have a gap relative to the wall, and can be flexibly plugged in relative to the plug-in portion, and the second side supports the first socket.

[0047] It adopts the design of two flat fixing holes on both sides, which are fixed to the wall by bolts, rivets or other fasteners. The double-hole fixation is more stable.

[0048] Further, such as Figure 1 and Figure 2As shown, the first socket 22 is connected to one end of the first connecting portion. The first socket 22 is shorter than the other end of the first connecting portion and forms a first notch 23. The second socket 31 fits in the first notch 23. That is, one end of the first connecting portion is connected to the bottom surface of the first socket 22, and the other end of the first connecting portion is provided with a baffle 212 connected to the side surface of the first socket, thereby forming the first notch 23 between the end surface of the first socket 22 and the first socket 22.

[0049] The cleverness of the reverse cross-staggered design of the first and second components is that the first socket and the second socket can be sequentially connected with the plug-in part of the plane fixing seat along the extension direction of the plug-in part and can fit with the plane part below, and the three form a whole, and the structure is more stable. In addition, while ensuring safety and stability, the first connecting part and the second connecting part are respectively at the same height as the connecting parts of the first photovoltaic component and the second photovoltaic component, so that the components on both sides can be kept on the same horizontal line, and the overall effect is more beautiful after installation.

[0050] It is understood that the movable plug-in structure between the first component 2 and the second component 3 and the planar fixing base 1 can also be modified. For example, the plug-in parts and the plug holes between the first component 2 and the second component 3 and the planar fixing base 1 can be interchanged. The specific structure of the first component 2, the second component 3 and the planar fixing base 1 can also be modified.

[0051] To facilitate connection with the photovoltaic module frame, the first connection portion is provided with a first connection plane 21 parallel to the fixing plane, and the first connection plane 21 is provided with a first connection hole 211; the second connection portion is provided with a second connection plane 32 parallel to the fixing plane, and the second connection plane 32 is provided with a second connection hole 321. The first connection plane 21 and the second connection plane 32 are parallel to the fixing plane and can be fixed to the fixing plane. The photovoltaic module frame 4 is provided with a bottom edge 41 and a top edge 42, and the bottom edge 41 is provided with a mounting hole 411. The bottom edge 41 is in contact with the first connection plane 21 or the second connection plane 32, thereby ensuring that the photovoltaic module is parallel to the fixing plane after installation, and the overall appearance is relatively flat and beautiful. In order to improve the overall flatness, the specifications of the outer surfaces of the first and second sockets are reasonably designed so that the outer surfaces of the first and second sockets can be flush with the outer surface of the photovoltaic module frame (top edge 42 in the figure). In addition, the mounting hole 411 can be connected to the first connection hole 211 or the second connection hole 321 by bolts, and the first connection hole 211 and the second connection hole 321 are both single-hole designs, which are connected and fixed to the mounting hole of the component frame to achieve quick and reliable fixation. In combination with the reverse cross-staggered design of the first and second components, the first connection hole 211 and the second connection hole 321 are designed to be at the same height in the vertical direction. Since the mounting holes on the first photovoltaic module and the second photovoltaic module are fixed in position, this ensures that the first photovoltaic module and the second photovoltaic module on both sides are kept on the same horizontal line. Since the first connection plane and the second connection plane are located on the back of the photovoltaic module frame, they do not occupy the gap width space between the first photovoltaic module and the second photovoltaic module, which is conducive to narrowing the gap. Moreover, compared with conventional pressing blocks, the first connection hole and the second connection hole are fixed to the mounting hole on the back of the photovoltaic module frame, cleverly utilizing the photovoltaic module itself to shield the structural components from sunlight exposure and rain erosion, avoiding rust at the connection parts, thereby achieving better quality and longer service life.

[0052] Preferably, the plug-in portion 12 is provided with a plurality of first cavities 121; the side walls of the first insertion hole 22 and the second insertion hole 31 are provided with a plurality of second cavities 311. This can save materials while ensuring sufficient strength. The hollow design has lower material costs, is more lightweight, and is convenient for construction.

[0053] Preferably, the planar mounting base 1, first component 2, and second component 3 are profiled; they are made of aluminum alloy or stainless steel. Lightweight metal materials, such as stamped aluminum alloy / stainless steel, can be used, offering high strength and corrosion resistance. This not only increases service life (up to 25 years), enabling single-installation functionality throughout the entire lifecycle, but also allows for mass production to reduce manufacturing costs. Furthermore, since the frame is typically also stamped aluminum alloy / stainless steel, the two can be made to a consistent color, enhancing the aesthetics.

[0054] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art will understand that the utility model includes, but is not limited to, the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the utility model are intended to be included within the scope of the claims.
