Description

[Technical field]

[0001] The invention belongs to the field of photovoltaic technology, and in particular relates to photovoltaic installation technology. [Background technology]

[0002] At present, photovoltaic modules are mainly installed on the roof, and a mounting bracket is 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-pressure block structures are often used for fixing. Referring to the Chinese utility model patent with reference announcement number CN215934792U, a wall photovoltaic module is disclosed, including a frame, a symmetrically arranged rear side of the frame is symmetrically provided with fixing rods, a limiting seat is arranged between the symmetrically arranged frames, a movable block is fixed to the bottom end of the limiting seat, a movable groove is provided on the surface of the fixing rod, a card block is symmetrically fixed on the inner side of the movable groove, a card slot is symmetrically provided at the bottom end of the movable block, and a connecting plate is provided on the inner side of the card slot, a connecting spring is connected between the connecting plate and the card block, and mounting holes are provided on the inner side of the limiting seat and the fixing rod. Conventional block structures require bracket installation on the wall first, and then the conventional block connection components are installed and fixed. The installation method is cumbersome and the stability is poor. When fixing, multiple people are required to lift the components and fix the blocks. The construction efficiency is low and the cost expenditure is high. After the conventional block is installed, it protrudes from the component frame, the component gap is large, the appearance is poor, and it is very easy to cause self-corrosion in the later period due to long-term wind and sun exposure. There are certain safety hazards and increase the operation and maintenance cost expenditure. [Summary of the invention]

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a photovoltaic component fixing device 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 prior art.

[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, and 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 sequentially plugged into the plug-in portion 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 that are vertically connected, 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 part side by side along the extension direction of the plug-in part, the first connecting part is provided on the first side of the first socket, and the second connecting part is provided on the second side of the second socket.

[0010] Preferably, the first jack is connected to one end of the first connecting portion, the first jack is shorter than the other end of the first connecting portion and forms a first notch, and the second jack matches 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 component and a second photovoltaic component arranged side by side, and also comprising the photovoltaic component fixing member, wherein the photovoltaic component fixing member mounts the first photovoltaic component and the second photovoltaic component on a fixed plane.

[0015] The present invention adopts the above technical solution and has the following beneficial effects:

[0016] 1. The entire photovoltaic module fixture includes a plane fixing seat, a first component and a second component. These three components are split structural parts, wherein the plane fixing seat is installed on the fixed plane, and the first component and the second component are assembled with the plane fixing seat in the form of an inlay (active plug-in) combination, and finally the adjacent first photovoltaic module and the second photovoltaic module are connected to the first component and the second component respectively. Since the split components of the photovoltaic module fixture use an inlay (active plug-in) combination form, there is no need to use fasteners for additional fixation, which is not only convenient for construction, but also more convenient for later operation and maintenance. The first component and the second component can be easily separated from the plane fixing seat, thereby improving the construction and operation efficiency and reducing the cost of later operation and maintenance.

[0017] In addition, the first connection part is arranged on the first side of the plane fixing seat and connected to the first photovoltaic module, and the second connection part is arranged on the second side of the plane fixing seat and connected to the second photovoltaic module, so that one photovoltaic module fixing piece is provided, two adjacent photovoltaic modules can be fixed at the same time, so that multiple photovoltaic modules can be fixed side by side to form a photovoltaic array. And compared with the conventional pressing block installation structure in the prior art, the number of components is relatively reduced, which reduces the cost expenditure.

[0018] 2. The plane part is connected to the fixed plane. Since the extension direction of the plug-in part is parallel to the side frame where the first photovoltaic module and the second photovoltaic module meet, and the first component and the second component are sequentially plugged into the plug-in part along the extension direction of the plug-in part, the three components of the plane fixing seat, the first component and the second component can be compactly combined into one. Since the first component and the second component are sequentially plugged into the plug-in part along the extension direction of the plug-in part, the space occupied by the plug-in part of the first component and the second component in the horizontal width direction can be reduced, which is conducive to reducing the gap between the first photovoltaic module and the second photovoltaic module.

[0019] 3. The plane part 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 part 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 relative to the plug-in part, and the first socket is supported by the second side.

[0020] 4. The length direction of the plane part is perpendicular to the length direction of the plug-in part and the length of the plane part is greater than the width of the plug-in part, so that the plane part and the plug-in part are in a T-shaped structure as a whole. Since it is installed on the wall, the plane part is set at the bottom, and the length direction of the plane part is parallel to the horizontal plane, so the upward extension direction of the plug-in part is mainly used to realize the first plug hole and the second plug hole are plugged into the plug-in part in sequence along the extension direction of the plug-in part, wherein the plane part supports the first plug hole, and the first plug hole supports the second plug hole. Since the first connecting part is set on the first side of the first plug hole and the second connecting part is set on the second side of the second plug hole, the first connecting part and the second connecting part are correspondingly located on the first side and the second side of the fixing part. In this way, the height of the first plug hole and the second plug hole 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 part, it is helpful to reduce the gap between two adjacent photovoltaic components in the horizontal direction.

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

[0022] 5. The second plug hole cooperates with the first notch to form a reverse cross-staggered design of the first component and the second component. The cleverness lies in that the first plug hole and the second plug hole can be sequentially plugged into 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. The three form a whole, and the structure is more stable. In addition, the upper end faces of the first component and the second component are flush, which can ensure safety and stability while also ensuring 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, and the photovoltaic module itself is cleverly used 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. Each split component of the photovoltaic module fixing can adopt a hollow design, that is, a certain number of cavities are added, so that the material cost is lower, it is lighter and easier to construct.

[0025] 8. Each component of the photovoltaic module fixing can be made of aluminum alloy or stainless steel, which can not only increase the service life (up to 25 years), but also achieve one-time installation and meet the function of the whole life cycle. In addition, the color of the fixing is consistent with the frame of the module, which is more coordinated and beautiful. In addition, it can be mass-produced, such as by 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, the photovoltaic component fixing part is installed on a fixed plane, and the fixed plane can be a wall. Therefore, the installation on the wall is taken as an example for explanation, and includes a plane fixing seat 1 installed on the fixed plane, and a first component 2 and a second component 3 movably plugged with the plane fixing seat 1. The first component 2 is provided with a first connection portion connected to the first photovoltaic component on the first side of the plane fixing seat 1, and the second component 3 is provided with a second connection portion connected to the second photovoltaic component on the second side of the plane fixing seat 1. Here, the first side and the second side refer to the opposite sides of the photovoltaic component fixing part corresponding to the connection with the first photovoltaic component and the second photovoltaic component, that is, the left and right sides.

[0040] The entire photovoltaic module fixture includes a plane fixing seat, a first component and a second component. These three components are split structural parts, wherein the plane fixing seat is installed on the fixing plane, and the first component and the second component are assembled with the plane fixing seat in the form of an inlay (active plug-in) combination, and finally the adjacent first photovoltaic module and the second photovoltaic module are connected to the first component and the second component respectively. Since the split components of the photovoltaic module fixture use an inlay (active plug-in) combination form, there is no need to use fasteners for additional fixing, which is not only convenient for construction, but also more convenient for later operation and maintenance. The first component and the second component can be easily separated from the plane fixing seat, thereby improving the construction and operation efficiency and reducing the cost of later operation and maintenance.

[0041] In addition, the first connection part is arranged on the first side of the plane fixing seat and connected to the first photovoltaic module, and the second connection part is arranged on the second side of the plane fixing seat and connected to the second photovoltaic module, so that one photovoltaic module fixing piece is provided, two adjacent photovoltaic modules can be fixed at the same time, so that multiple photovoltaic modules can be fixed side by side to form a photovoltaic array. And compared with the conventional pressing block installation structure in the prior art, the number of components is relatively reduced, which reduces the cost expenditure.

[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 up-down 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 are supported by the plane fixing seat 1 below, 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 plane portion 11 is L-shaped, including a first side 111 and a second side 112 connected vertically, the first side is in contact with the fixed plane, and the second side is connected to the plug-in portion. The length direction of the plane portion 11 is perpendicular to the length direction of the plug-in portion 12, and the length of the plane portion is greater than the width of the plug-in portion. The plane portion is provided with a plane fixing hole 113 on both sides of the length. The first component is provided with a first plug hole 22, and the second component is provided with a second plug hole 31. The first plug hole 22 and the second plug hole 31 are sequentially plugged with the plug-in portion along the extension direction of the plug-in portion. The first connection portion is provided on the first side of the first plug hole 22, and the second connection portion is provided on the second side of the second plug hole 31. The plug-in portion 12 is a rectangular cylinder, and the first plug hole 22 and the second plug 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 arranged 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 plug hole and the second plug hole being sequentially plugged into the plug-in portion along the extension direction of the plug-in portion. In this way, the heights of the first plug hole and the second plug hole protruding from the wall can be kept consistent, and the lateral occupied space will not be increased, so that when the photovoltaic components are installed using the fixing member, it is beneficial to reduce the gap between two adjacent photovoltaic components in the horizontal direction.

[0045] In addition, the plane portion supports the first plug hole, and the first plug hole supports the second plug hole. Since the first connecting portion is arranged on the first side of the first plug hole and the second connecting portion is arranged on the second side of the second plug hole, the first connecting portion and the second connecting portion are correspondingly 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 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 relative to the plug-in portion, and the first socket is supported by the second side.

[0047] The design adopts 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 plug hole 22 is connected to one end of the first connection part, the first plug hole 22 is shorter than the other end of the first connection part and forms a first notch 23, and the second plug hole 31 matches the first notch 23. That is, one end of the first connection part is connected to the bottom surface of the first plug hole 22, and the other end of the first connection part is provided with a baffle 212 connected to the side surface of the first plug hole, so as to form the first notch 23 between the end surface of the first plug hole 22.

[0049] The ingenious design of the reverse cross-staggered design of the first component and the second component is that the first socket and the second socket can be sequentially plugged into the plug-in part of the planar 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 with a more stable structure. 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 understandable that the movable plug-in structure between the first component 2, the second component 3 and the plane fixing seat 1 can also be changed, for example, the plug-in parts and the plug holes between the first component 2, the second component 3 and the plane fixing seat 1 can be interchanged. The specific structure of the first component 2, the second component 3 and the plane fixing seat 1 can also be changed.

[0051] In order to facilitate the connection with the photovoltaic module frame, the first connection part is provided with a first connection plane 21 parallel to the fixed plane, and the first connection plane 21 is provided with a first connection hole 211; the second connection part is provided with a second connection plane 32 parallel to the fixed 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 fixed plane and can be fitted and fixed to the fixed 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 fits the first connection plane 21 or the second connection plane 32, so that the photovoltaic module can be parallel to the fixed 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 can be reasonably designed to make the outer surfaces of the first and second sockets flush with the outer surface of the photovoltaic module frame (the 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 with the mounting hole of the component frame to achieve fast and reliable fixation. Combined with the reverse cross-staggered design of the first component and the second component, the first connection hole 211 and the second connection hole 321 are designed to be equal in height in the up and down directions. Since the positions of the mounting holes on the first photovoltaic component and the second photovoltaic component are fixed, the first photovoltaic component and the second photovoltaic component on both sides can be kept on the same horizontal line. Since the first connection plane and the second connection plane are located on the back of the photovoltaic component frame, they do not occupy the gap width space between the first photovoltaic component and the second photovoltaic component, 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 hole on the back of the photovoltaic component frame, and the photovoltaic component itself is cleverly used to shield the structural parts from sun exposure and rain erosion, avoiding rusting of the connection parts, so that the quality is better and the service life is longer.

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

[0053] Preferably, the plane fixing seat 1 and the first component 2 and the second component 3 are profiles; the plane fixing seat 1 and the first component 2 and the second component 3 are made of aluminum alloy or stainless steel. Lightweight metal materials can be used, such as aluminum alloy / stainless steel stamping, which has high strength and corrosion resistance, which can not only increase the service life (up to 25 years) and achieve one-time installation to meet the functions of the entire life cycle; but also can be mass-produced to reduce manufacturing costs. In addition, since the frame is usually also made of aluminum alloy / stainless steel stamping, the two can be made of the same color, which is more beautiful.

[0054] The above is only a specific embodiment of the invention, but the protection scope of the invention is not limited thereto. Those skilled in the art should understand that the invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the invention will be included in the scope of the claims.
