Description

Technical Field

[0001] This invention relates to the field of building photovoltaic technology, specifically to photovoltaic module structures and methods for installing and dismantling photovoltaic module structures. Background Technology

[0002] As a green building material that combines aesthetics and functionality, photovoltaic module structures can meet the market demand for green building materials and have broad market prospects.

[0003] A photovoltaic module structure generally consists of photovoltaic modules and frame components. The photovoltaic modules are fixed by the frame components, and multiple photovoltaic module structures are interconnected to form a photovoltaic building roof.

[0004] However, the existing photovoltaic module structures typically involve cumbersome installation methods such as frame overlap, mold installation and bonding, bolt fixing, and profile hanging. Furthermore, when a photovoltaic module structure is damaged and needs replacement, the fixing structures of adjacent photovoltaic modules must be completely removed, which is a complicated and inconvenient operation. Summary of the Invention

[0005] In view of this, the present invention provides a photovoltaic module structure and a method for installing and dismantling the photovoltaic module structure, so as to solve the problem that the installation and dismantling of existing photovoltaic module structures are cumbersome and inconvenient to use.

[0006] In a first aspect, the present invention provides a photovoltaic module structure, comprising: a plurality of photovoltaic units stacked in a staggered manner from bottom to top, wherein a support structure is provided below the photovoltaic unit, and the downward degree of freedom is limited by the support structure, and the position of the upper-level photovoltaic unit relative to the lower-level photovoltaic unit is adjusted in the laying extension direction;

[0007] The photovoltaic unit at the previous level is provided with a support member, and the photovoltaic unit is connected to the load-bearing structure through the support member. The support member elastically pulls the photovoltaic unit at the previous level onto the photovoltaic unit at the next level in the stacking direction of the photovoltaic units.

[0008] Beneficial Effects: The photovoltaic module structure of this invention features a series of photovoltaic units stacked in a staggered manner. The upper end of each photovoltaic unit is movably mounted on a supporting structure, while the lower end is connected to the supporting structure of the next-level photovoltaic unit via a support member. No additional fixing structure is required, simplifying operation and facilitating installation. Furthermore, adjacent photovoltaic units can be adjusted in the laying direction. Disassembly is easy by simply detaching the support member of the upper-level photovoltaic unit from the supporting structure of the lower-level unit and then lifting the photovoltaic unit. Each photovoltaic unit can be installed and disassembled independently, enhancing usability. The support member itself has elastic deformation, allowing it to elastically pull the upper-level photovoltaic unit in the stacking direction, causing the upper-level unit to press down on the lower-level unit, thereby improving the seismic resistance of the photovoltaic module structure. Moreover, the supporting structure can also limit and support the photovoltaic units, thus improving the structural stability of the photovoltaic modules.

[0009] In one optional embodiment, an elastic element is provided on the contact surface between the photovoltaic unit at the upper level and the photovoltaic unit at the lower level.

[0010] Beneficial effects: An elastic element is installed on the contact surface between the upper-level photovoltaic unit and the lower-level photovoltaic unit. The elasticity of the elastic element can further improve the seismic resistance. In addition, the elastic element can also block rainwater and has good waterproof performance.

[0011] In one optional embodiment, the photovoltaic unit includes a photovoltaic module and a frame assembly disposed around the photovoltaic module. The frame assembly includes an upper frame located above the photovoltaic module and a lower frame located below the photovoltaic module. One of the lower frames is elastically pressed onto the upper frame of an adjacent photovoltaic unit.

[0012] Beneficial effects: The frame assembly protects the photovoltaic (PV) modules, preventing them from loosening or deforming due to external pressure such as wind, rain, and snow. The lower frame elastically presses against the upper frame of an adjacent PV unit, without obstructing the modules, and ensures a tight, sealed connection between adjacent units, preventing rainwater from seeping in through the gaps between the upper and lower frames. Additionally, it creates a height difference for water flow, preventing internal water leakage.

[0013] In one optional embodiment, the lower frame includes a first profile, which extends to form a first extension arm on the side near the photovoltaic module. The first extension arm is fixedly connected to the support member to form a first fixing part, and the first fixing part is spaced apart from the first profile.

[0014] Beneficial effects: The first profile is used to form the support structure of the lower frame, which improves the structural stability of the lower frame. The first extension arm is used to be fixedly connected with the support and form the first fixing part. The first fixing part is set at a distance from the first profile, which can provide deformation space for the support and further improve the seismic resistance.

[0015] In one alternative embodiment, the upper frame includes a second profile, the upper end of which is connected to a second extension arm opposite to the second profile, the second extension arm supporting the lower frame of the upper-level photovoltaic unit.

[0016] Beneficial effects: The second profile is used to form the support structure of the upper frame and can connect the second extension arm. The second extension arm is used to support the lower frame of the upper photovoltaic unit and provide deformation capacity, further improving the seismic resistance. It also provides more space for installation and disassembly, and facilitates the installation and disassembly of photovoltaic units.

[0017] In one optional embodiment, the support member includes a plug-in section, a support section, and a fixing section. The plug-in section and the fixing section are respectively disposed at both ends of the support section, and the fixing section is connected to the lower frame. The plug-in section is movably plugged into the load-bearing structure in the laying extension direction. The support sections are spaced apart from the load-bearing structure, and the support section, the upper frame, the lower frame, and the load-bearing structure together enclose a deformation compensation area.

[0018] Beneficial effects: The support section supports the plug-in section and the fixed section. The plug-in section is used to movably connect to the load-bearing structure to fix the support and the load-bearing structure. Disassembly of the support and the load-bearing structure can be achieved simply by pulling the plug-in section out of the load-bearing structure; the operation is simple. The fixed section is used to fix the lower frame. The support section, upper frame, lower frame, and load-bearing structure together enclose a deformation compensation zone to provide deformation space for the support, improve seismic resistance, and expand the installation and disassembly space of the photovoltaic unit, facilitating the installation and disassembly of the photovoltaic unit.

[0019] In one optional embodiment, one of the support member and the load-bearing structure is provided with a insertion groove, and the other is provided with a corresponding insertion protrusion.

[0020] Alternatively, the supporting structure may also be provided with a fixing member, one of the supporting member and the fixing member having a plug-in groove, and the other having a corresponding plug-in protrusion.

[0021] Beneficial effects: The support components and load-bearing structure are fastened together via interlocking slots and protrusions, resulting in a simple structure that is easy to manufacture and facilitates quick assembly and disassembly. Furthermore, the fastening method limits the height of the photovoltaic units on the load-bearing structure. Fixtures on the load-bearing structure interlock with the support components, facilitating rapid installation and disassembly of the support components.

[0022] In one optional embodiment, a limiting member is provided on the top surface of the load-bearing structure, and the upper frame is hung on the limiting member.

[0023] Beneficial effects: Hanging the upper frame on the limiting component allows the limiting component to support the upper frame and limit its position, thereby improving the structural stability of the photovoltaic unit.

[0024] In one alternative embodiment, the frame assembly further includes a left frame located to the left of the photovoltaic module and a right frame located to the right of the photovoltaic module;

[0025] The left frame has a downward-opening first water-blocking groove on the side opposite to the photovoltaic module, and the right frame has an upward-opening second water-blocking groove on the side opposite to the photovoltaic module. The first water-blocking groove of one photovoltaic unit and the second water-blocking groove of the adjacent photovoltaic unit overlap and interlock to form a water flow channel.

[0026] Beneficial effects: The left and right frames of adjacent photovoltaic units overlap each other, making installation convenient. The first and second water-blocking grooves overlap and interlock to form a water flow channel, which facilitates drainage and effectively prevents rainwater from seeping in.

[0027] Secondly, the present invention also provides a method for installing and disassembling a photovoltaic module structure, comprising:

[0028] Installation of photovoltaic module structure:

[0029] Install a flexible element on the bottom of the lower frame of the photovoltaic unit to be installed;

[0030] Install a support on the first extension arm on the lower frame of the photovoltaic unit to be installed;

[0031] The upper frame of the photovoltaic unit to be installed can be directly hung on the supporting structure; or, a limiting component can be set on the upper surface of the supporting structure first, and then the upper frame of the photovoltaic unit to be installed can be hung on the limiting component.

[0032] Simultaneously, the elastic element of the photovoltaic unit to be installed is pressed onto the second extension arm of the next-level photovoltaic unit. In the laying extension direction, the position is adjusted and the plug-in section of the support is inserted into the next-level load-bearing structure or fixing component, and the installation is completed.

[0033] Disassembly of photovoltaic module structure:

[0034] Push the photovoltaic unit to be disassembled upwards a certain distance along the laying direction so that the plug section of the support component is detached from the load-bearing structure or fixing component;

[0035] Lift the top and bottom of the photovoltaic unit to be disassembled upwards, and then remove the photovoltaic unit downwards.

[0036] Beneficial Effects: The photovoltaic module structure of this invention involves the staggered stacking of several photovoltaic units. The upper frame of each photovoltaic unit is movably hung on a supporting structure, while the lower frame of the photovoltaic unit has a first extension arm. This first extension arm is connected to the supporting structure of the next-level photovoltaic unit via a support member. No additional fixing structure is required, making operation simple and installation convenient. Simultaneously, the support member itself has elastic deformation, allowing it to elastically pull the upper-level photovoltaic unit in the stacking direction, causing the upper-level unit to press onto the lower-level unit. Furthermore, elastic elements are provided at the contact surface between the upper and lower-level photovoltaic units, enhancing the seismic resistance of the photovoltaic module structure. In addition, the supporting structure can limit and support the photovoltaic units, thereby improving the structural stability of the photovoltaic units.

[0037] The photovoltaic module structure of this invention can be disassembled simply by pushing the photovoltaic unit to be disassembled upwards a certain distance along the laying direction, causing the plug-in section of the support member to detach from the load-bearing structure or fixing member. Then, the top and bottom of the photovoltaic unit to be disassembled can be lifted to remove the photovoltaic unit, making disassembly convenient. Each photovoltaic unit can be installed and disassembled independently, facilitating use. Attached Figure Description

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] The following is combined with Figures 1 to 9 The following describes embodiments of the present invention.

[0052] According to embodiments of the present invention, in one aspect, such as Figure 1 As shown, a photovoltaic module structure is provided, including: a plurality of photovoltaic units 1 stacked in a staggered manner from bottom to top, a supporting structure 2 provided below the photovoltaic unit 1, and the downward degree of freedom is limited by the supporting structure 2, and the position of the upper-level photovoltaic unit 1 relative to the lower-level photovoltaic unit 1 in the laying extension direction is adjusted.

[0053] A support member 3 is provided on the upper-level photovoltaic unit 1. The photovoltaic unit 1 is connected to the bearing structure 2 through the support member 3, and the support member 3 elastically pulls the upper-level photovoltaic unit 1 to press it onto the lower-level photovoltaic unit 1 in the stacking direction of the photovoltaic units 1.

[0054] Therefore, the photovoltaic module structure provided in this embodiment of the invention features a series of photovoltaic units 1 stacked in a staggered manner. The upper end of each photovoltaic unit 1 is movably mounted on the supporting structure 2, and the lower end is connected to the supporting structure 2 of the next-level photovoltaic unit 1 via a support member 3. No additional fixing structure is required, making operation simple and installation convenient. Furthermore, adjacent photovoltaic units 1 can be adjusted in the laying extension direction. Simply detach the support member 3 of the upper-level photovoltaic unit 1 from the supporting structure 2 of the lower-level photovoltaic unit 1, and then lift the photovoltaic unit 1 to disassemble it, making disassembly convenient. Each photovoltaic unit 1 can be installed and disassembled independently, facilitating use. The support member 3 itself has elastic deformation, allowing it to elastically pull the upper-level photovoltaic unit 1 in the stacking direction, causing the upper-level photovoltaic unit 1 to press onto the lower-level photovoltaic unit 1, thereby improving the seismic resistance of the photovoltaic module structure. Moreover, the supporting structure 2 can also limit and support the photovoltaic units 1, thereby improving the structural stability of the photovoltaic units 1.

[0055] Specifically, the upper-level photovoltaic unit 1 and the lower-level photovoltaic unit 1 refer to two photovoltaic units 1 that are adjacent in height. The load-bearing structure 2 can be a beam on the roof.

[0056] Specifically, photovoltaic unit 1 includes, but is not limited to, photovoltaic tiles.

[0057] In one embodiment, such as Figure 1 and Figure 2 As shown, an elastic element 10222 is provided on the contact surface between the upper-level photovoltaic unit 1 and the lower-level photovoltaic unit 1. The elastic element 10222's elasticity further enhances the seismic resistance, and it also effectively blocks rainwater, providing good waterproofing. The elastic element 10222 can be made of rubber strip.

[0058] Furthermore, in one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the photovoltaic unit 1 includes a photovoltaic module 101 and a frame assembly 102 disposed around the photovoltaic module 101. The frame assembly 102 includes an upper frame 1021 located above the photovoltaic module 101 and a lower frame 1022 located below the photovoltaic module 101. The lower frame 1022 elastically presses against the upper frame 1021 of the adjacent photovoltaic unit 1.

[0059] The frame assembly 102 protects the photovoltaic module 101, preventing it from loosening or deforming due to external wind pressure, rain, snow, or other heavy forces. The lower frame 1022 elastically presses against the upper frame 1021 of an adjacent photovoltaic unit 1, without obstructing the photovoltaic module 101, while ensuring a tight connection between adjacent photovoltaic units 1, forming a sealed connection and preventing rainwater from seeping in through the gap between the upper and lower frames 1021 and 1022. Additionally, it creates a height difference for water flow, preventing internal water leakage. The overall operating cost is also low, facilitating widespread adoption.

[0060] Specifically, the directions "up", "down", "left", and "right" in the embodiments of the present invention are as follows: Figure 3 As shown.

[0061] It should be noted that the embodiments of the present invention do not restrict the fixed connection method between the upper frame 1021, the lower frame 1022, the left frame 1023 and the right frame 1024 and the photovoltaic module 101, such as by adhesive bonding, fastener fixing, etc.

[0062] Furthermore, in one embodiment, such as Figure 4 As shown, the lower frame 1022 includes a first profile 10221. The first profile 10221 extends to the side near the photovoltaic module 101 to form a first extension arm 10223. The first extension arm 10223 is fixedly connected to the support member 3 to form a first fixing part. The first fixing part is spaced apart from the first profile 10221.

[0063] The first profile 10221 forms a support structure for the lower frame 1022, improving the structural stability of the lower frame 1022. The first profile 10221 has a cavity. The cross-section of the cavity can be selected according to actual needs, for example, it can be rectangular. The first extension arm 10223 is fixedly connected to the support member 3 to form a first fixing part. The first fixing part is spaced apart from the first profile 10221, providing deformation space for the support member 3 and further improving the seismic resistance.

[0064] Specifically, the upper end of the first profile 10221 extends to form a third extension arm 10226, which, together with the first profile 10221, forms an mounting step 10224 for mounting the photovoltaic module 101. The lower side of the photovoltaic module 101 is placed on the mounting step 10224 and fixed with adhesive or screws, which prevents dust accumulation. The lower end of the first profile 10221 is also provided with a slot 10225 for mounting the elastic element 10222.

[0065] Furthermore, in one embodiment, such as Figure 5As shown, the upper frame 1021 includes a second profile 10211. The upper end of the second profile 10211 is connected to a second extension arm 10212 away from the second profile 10211. The second extension arm 10212 supports the lower frame 1022 of the upper photovoltaic unit 1.

[0066] The second profile 10211 forms a support structure for the upper frame 1021 and connects to the second extension arm 10212. A cavity may also be provided within the second profile 10211. The second extension arm 10212 supports the lower frame 1022 of the upper photovoltaic unit 1 and provides deformation capacity to further improve the seismic resistance. It also provides more space for installation and disassembly, and facilitates the installation and disassembly of the photovoltaic unit 1.

[0067] Specifically, such as Figure 5 As shown, the second extension arm 10212 is T-shaped. One end of the second extension arm 10212, which is away from the second profile 10211, is used to support the lower frame 1022 of the upper-level photovoltaic unit 1. The other end of the second extension arm 10212 and the second profile 10211 together form a mounting groove 10213 for mounting the photovoltaic module 101. The upper side of the photovoltaic module 101 is inserted into the mounting groove 10213 and fixed by adhesive.

[0068] In one embodiment, such as Figure 2 As shown, the support member 3 includes a plug-in section 301, a support section 302, and a fixing section 303. The plug-in section 301 and the fixing section 303 are respectively disposed at both ends of the support section 302, and the fixing section 303 is connected to the lower frame 1022. The plug-in section 301 is movably plugged into the load-bearing structure 2 in the laying extension direction. The support section 302 is spaced apart from the load-bearing structure 2, and the support section 302, the upper frame 1021, the lower frame 1022, and the load-bearing structure 2 together enclose and form a deformation compensation area 304.

[0069] The support section 302 supports the plug-in section 301 and the fixing section 303. The plug-in section 301 is used to movably plug into the load-bearing structure 2 to fix the support member 3 and the load-bearing structure 2. The support member 3 and the load-bearing structure 2 can be disassembled by pulling out the plug-in section 301 from the load-bearing structure 2, which is simple to operate. The fixing section 303 is used to fixally connect to the lower frame 1022. The support section 302, the upper frame 1021, the lower frame 1022 and the load-bearing structure 2 together enclose the deformation compensation area 304 to provide deformation space for the support member 3, improve the seismic resistance, and expand the installation and disassembly space of the photovoltaic unit 1, making the installation and disassembly of the photovoltaic unit 1 easier.

[0070] It should be noted that the embodiments of the present invention do not limit the connection method between the fixed segment 303 and the lower frame 1022, and any existing connection method can be selected as needed. For example, Figure 2As shown, the fixed section 303 and the lower frame 1022 are fixedly connected by the second fastener 6, which can be a screw, bolt, etc.

[0071] Furthermore, in one embodiment, one of the support member 3 and the load-bearing structure 2 is provided with a plug-in groove, and the other is provided with a corresponding plug-in protrusion.

[0072] Alternatively, the supporting structure 2 may also be provided with a fastener 201, and one of the support member 3 and the fastener 201 may be provided with a plug-in groove, and the other may be provided with a corresponding plug-in protrusion.

[0073] The support member 3 and the load-bearing structure 2 are fastened together by a plug-in groove and a plug-in protrusion. This simple structure is easy to manufacture and facilitates quick fastening and disassembly of the support member 3 and the load-bearing structure 2. Furthermore, the fastening method limits the height of the photovoltaic unit 1 on the load-bearing structure 2. A fixing member 201 is provided on the load-bearing structure 2 to plug into the support member 3, facilitating the quick installation and removal of the support member 3.

[0074] For example, the end of the insertion section 301 of the support member 3 serves as an insertion protrusion, and the bearing structure 2 is provided with a fixing member 201 on the side near the support member 3, and the fixing member 201 is provided with an insertion groove.

[0075] Furthermore, in one embodiment, such as Figure 2 As shown, a limiting member 202 is provided on the top surface of the supporting structure 2, and the upper frame 1021 is hung on the limiting member 202. Hanging the upper frame 1021 on the limiting member 202 can support the upper frame 1021 and limit its movement, thereby improving the structural stability of the photovoltaic unit 1.

[0076] Specifically, such as Figure 2 As shown, the top surface of the supporting structure 2 is fixedly connected to the limiting member 202 by the first fastener 4. The limiting member 202 can be integrally formed with the fixing member 201. The first fastener 4 also protrudes from the limiting member 202 through its surface and is located at the lower end of the upper frame 1021. The first fastener 4 is used to further support and limit the upper frame 1021. The first fastener 4 can be a screw, bolt, etc.

[0077] In one embodiment, such as Figure 3 As shown, the frame assembly 102 also includes a left frame 1023 located to the left of the photovoltaic module 101 and a right frame 1024 located to the right of the photovoltaic module 101.

[0078] Furthermore, such as Figures 6 to 8As shown, the left frame 1023 has a first water-blocking groove 10231 with an opening facing downward on the side opposite to the photovoltaic module 101, and the right frame 1024 has a second water-blocking groove 10241 with an opening facing upward on the side opposite to the photovoltaic module 101. The first water-blocking groove 10231 of one photovoltaic unit 1 and the second water-blocking groove 10241 of the adjacent photovoltaic unit 1 overlap and interlock with each other to form a water flow channel 1025.

[0079] The left frame 1023 and right frame 1024 of adjacent photovoltaic units 1 overlap each other, making installation convenient. The first water blocking groove 10231 and the second water blocking groove 10241 overlap and interlock to form a water flow channel 1025, which facilitates drainage and effectively prevents rainwater from seeping in.

[0080] In one embodiment, such as Figure 9 As shown, the adjacent ends of the upper frame 1021, lower frame 1022, left frame 1023, and right frame 1024 are fixedly connected by corner brackets 5. The corner brackets 5 are L-shaped with serrations on the inner side, and their two ends are fixed in the adjacent cavities respectively.

[0081] According to an embodiment of the present invention, in another aspect, a method for installing and dismantling a photovoltaic module structure is also provided, wherein the method for installing the photovoltaic module structure includes:

[0082] S100. Install the elastic element 10222 on the bottom of the lower frame 1022 of the photovoltaic unit 1 to be installed.

[0083] S200. Install the support 3 on the first extension arm 10223 on the lower frame 1022 of the photovoltaic unit 1 to be installed.

[0084] S300, directly hang the upper frame 1021 of the photovoltaic unit 1 to be installed on the supporting structure 2; or, first set the limiting member 202 on the upper surface of the supporting structure 2, and then hang the upper frame 1021 of the photovoltaic unit 1 to be installed on the limiting member 202.

[0085] Simultaneously, the elastic element 10222 of the photovoltaic unit 1 to be installed is pressed onto the second extension arm 10212 of the next-level photovoltaic unit 1. In the laying extension direction, the position is adjusted and the plug section 301 of the support 3 is inserted into the next-level load-bearing structure 2 or the fixing element 201, and the installation is completed.

[0086] Methods for disassembling photovoltaic module structures include:

[0087] S400, push the photovoltaic unit 1 to be disassembled upward a distance along the laying direction so that the plug section 301 of the support 3 is disengaged from the load-bearing structure 2 or the fixing member 201.

[0088] S500: Lift the top and bottom of the photovoltaic unit 1 to be disassembled upwards, and then remove the photovoltaic unit 1 downwards.

[0089] The photovoltaic module installation method provided in this embodiment of the invention involves stacking several photovoltaic units 1 in a staggered manner. The upper frame 1021 of each photovoltaic unit 1 is movably hung on the supporting structure 2, and the lower frame 1022 of each photovoltaic unit 1 is provided with a first extension arm 10223. The first extension arm 10223 is connected to the supporting structure 2 at the next-level photovoltaic unit 1 via a support member 3. No additional fixing structure is required, making the operation simple and convenient for installation. Simultaneously, the support member 3 itself has elastic deformation, which can elastically pull the upper-level photovoltaic unit 1 in the stacking direction of the photovoltaic units 1, causing the upper-level photovoltaic unit 1 to press onto the lower-level photovoltaic unit 1. Furthermore, an elastic member 10222 is provided at the contact surface between the upper-level and lower-level photovoltaic units 1, which can improve the seismic resistance of the photovoltaic module structure. In addition, the supporting structure 2 can also limit and support the photovoltaic units 1, thereby improving the structural stability of the photovoltaic units 1.

[0090] The method for disassembling a photovoltaic module structure provided in this embodiment of the invention only requires pushing the photovoltaic unit 1 to be disassembled upwards a certain distance along the laying direction, so that the insertion section 301 of the support member 3 disengages from the bearing structure 2 or the fixing member 201, and then lifting the top and bottom of the photovoltaic unit 1 to be disassembled, so that the photovoltaic unit 1 can be removed, which is convenient for disassembly. Each photovoltaic unit 1 can be installed and disassembled independently, which is convenient for use.

[0091] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
