Description

Technical Field

[0001] This invention relates to the field of photovoltaic cell support structures, specifically a photovoltaic cell mounting and fixing structure. Background Technology

[0002] As the core component of a photovoltaic power generation system, photovoltaic panels need to be installed and fixed on rooftops, ground surfaces, or photovoltaic brackets using supporting structures to ensure stable reception of sunlight for power generation. Currently, the installation and fixing of photovoltaic panels mostly uses bolts and nuts with clamps for fastening. Installation requires aligning holes, inserting bolts, and tightening them one by one; disassembly and maintenance similarly require loosening and unloading bolts one by one. This process is cumbersome, time-consuming on-site, and results in high labor costs.

[0003] Photovoltaic panels of different models and power ratings have varying dimensions, resulting in different mounting hole spacings. Existing fixed brackets have fixed mounting point spacing, which cannot flexibly adapt to various photovoltaic panel specifications. When replacing panels of different sizes, the bracket hole positions need to be readjusted or the brackets need to be replaced, resulting in poor versatility and hindering the mixed installation of multiple specifications of photovoltaic arrays and subsequent upgrades.

[0004] In addition, photovoltaic power stations are mostly located in outdoor environments, exposed to wind, sun and rain for a long time. Bolt connections are prone to corrosion and loosening, requiring regular inspection and maintenance. Furthermore, with rigid connections, wind vibrations can be directly transmitted to the solar panels, which can lead to hidden cracks in the panels and deformation of the frames over time, affecting the lifespan and power generation efficiency of the photovoltaic modules.

[0005] Therefore, there is a need to provide a mounting and fixing structure for photovoltaic cells, which aims to solve the above problems. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a mounting and fixing structure for photovoltaic cells.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic cell mounting and fixing structure, including a support frame and a photovoltaic cell panel, wherein the photovoltaic cell panel is disposed on the top of the support frame, a locking component is disposed at the bottom of the photovoltaic cell panel, and a plurality of spacing adjustment components are disposed on the top of the support frame, and a plurality of fixing and unlocking components are disposed on each of the spacing adjustment components. The locking component includes four positioning blocks, which are fixedly connected to the bottom of the photovoltaic panel in a rectangular arrangement. Limiting grooves are formed inside the positioning blocks. The spacing adjustment assembly includes a grooved plate assembly, which is snapped onto the top of the support frame. The grooved plate assembly is symmetrically rotatably connected to a threaded column inside, and several sets of rectangular sliders are symmetrically slidably connected inside. The fixed unlocking assembly includes two positioning cylinders, one of which is fixedly connected to the top of the groove plate assembly, and the other is fixedly connected to the top of the rectangular slider assembly. A second reset spring assembly is fixedly connected to the bottom of the inner cavity of each of the two positioning cylinders, and an abutment ring is fixedly connected to the end of the second reset spring assembly away from the positioning cylinder.

[0008] Preferably, the locking component includes a limiting slider group, which is slidably connected inside the limiting slide groove. A first reset spring group is provided inside the limiting slide groove. One end of the first reset spring group is connected to the limiting slider group, and the other end of the first reset spring group is fixedly connected to the positioning block.

[0009] Preferably, the spacing adjustment assembly includes a drive belt that is driven to the outer walls of two threaded posts, one of which has a rotating handle fixedly connected to its outer wall.

[0010] Preferably, both threaded posts are threadedly connected inside the rectangular slider assembly.

[0011] Preferably, the fixed unlocking assembly includes two limiting posts, which are respectively fixedly connected to the bottom of the inner cavity of the two positioning cylinders. An arc-shaped limiting block is fixedly connected to the top of each limiting post, a limiting ring is fixedly connected to the outer wall of each limiting post, and an unlocking paddle is slidably connected to the outer wall of each limiting post.

[0012] Preferably, the bottom surface of the arc-shaped limiting block is a horizontal supporting surface, the top surface of the arc-shaped limiting block is a guide slope, and the end of the limiting slider assembly is provided with a slope that matches the arc-shaped limiting block.

[0013] Preferably, the limiting ring is positioned below the unlocking lever.

[0014] Preferably, the positioning block is slidably connected inside the positioning cylinder.

[0015] Preferably, the bottom of the grooved plate assembly is provided with a locking block, and the grooved plate assembly is locked onto the top crossbeam of the support frame by the locking block.

[0016] The photovoltaic cell mounting and fixing structure provided by this invention has the following advantages compared with the prior art: By adopting a press-type quick-installation and quick-disassembly structure, when installing photovoltaic panels, simply align the positioning block with the positioning cylinder and press down to automatically complete the locking process; when disassembling, pressing down again will automatically unlock and remove the panels, eliminating the need for bolts, nuts, and tightening tools. This simplifies the installation and disassembly steps of photovoltaic panels, reduces on-site installation time, and lowers labor costs.

[0017] By setting an adjustable spacing structure, rotating the handle can simultaneously adjust the spacing of each group of rectangular sliders, thereby driving the top fixed unlocking component to adjust the spacing synchronously. It can adapt to the installation needs of photovoltaic panels of different shapes and sizes, has strong versatility, and can meet the needs of mixed installation of multiple specifications of photovoltaic modules and subsequent replacement and upgrade.

[0018] By integrating an elastic damping and buffering structure, after the photovoltaic panel is installed, the second reset spring group continuously pushes the positioning block to maintain the locked state through the contact ring; when subjected to external loads such as wind vibration and equipment resonance, the second reset spring group can absorb vibration energy through elastic deformation, buffer impact loads, reduce problems such as hidden cracks in the solar panel and loose bolts caused by rigid connection, and improve the operational stability of photovoltaic modules.

[0019] When the positioning block is inserted into the positioning cylinder, a sliding seal is formed, which can effectively prevent dust, rainwater and debris from entering the locking mechanism, avoid dust accumulation, rust and jamming of the internal springs and sliding components, reduce the maintenance frequency in outdoor environments, and is suitable for the long-term outdoor operation of photovoltaic power stations.

[0020] The entire device is a purely mechanical linkage structure, with no electrical components or sensor parts to rely on. It has a simple and reliable structure, a low failure rate, good outdoor high temperature resistance and corrosion resistance, low maintenance costs, and can stably adapt to the long-term operation requirements of photovoltaic power stations.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the invention and are not intended to limit the invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0026] Implementation, for example Figure 1 As shown, an embodiment of the present invention provides a photovoltaic cell mounting and fixing structure, including a support frame 11 and a photovoltaic panel 12. The photovoltaic panel 12 is disposed on the top of the support frame 11, and a locking component is disposed on the bottom of the photovoltaic panel 12. Several sets of spacing adjustment components are disposed on the top of the support frame 11, and several sets of fixing and unlocking components are disposed on the several sets of spacing adjustment components.

[0027] like Figure 2 and Figure 3 As shown, four positioning blocks 21 are rectangularly distributed and fixedly connected to the bottom of the photovoltaic panel 12. A limiting groove 22 is formed inside each positioning block 21. A limiting slider assembly 23 is slidably connected inside the limiting groove 22. A first return spring assembly 24 is provided inside the limiting groove 22. One end of the first return spring assembly 24 is connected to the limiting slider assembly 23, and the other end is fixedly connected to the positioning block 21.

[0028] It should be noted that the outer end of the limit slider assembly 23 is provided with a mating inclined surface, which can cooperate with the guide inclined surface of the arc-shaped limit block 33 to achieve automatic retraction under pressure and complete the locking action. The first reset spring assembly 24 is used to provide elastic reset force, so that the limit slider assembly 23 automatically pops out after passing the locking position, forming a lock.

[0029] like Figure 8 and Figure 9 As shown, of the two positioning cylinders 31, one positioning cylinder 31 is fixedly connected to the top of the groove plate assembly 41, and the other positioning cylinder 31 is fixedly connected to the top of the rectangular slider assembly 43. A second return spring assembly 36 is fixedly connected to the bottom of the inner cavity of each of the two positioning cylinders 31, and an abutment ring 37 is fixedly connected to the end of the second return spring assembly 36 away from the positioning cylinder 31.

[0030] It should be noted that: the two limiting posts 32 are fixedly connected to the bottom of the inner cavity of the two positioning cylinders 31 respectively, and an arc-shaped limiting block 33 is fixedly connected to the top of each limiting post 32. The bottom surface of the arc-shaped limiting block 33 is a horizontal supporting surface, and the top surface is a guide slope. The horizontal supporting surface is used to abut against the top surface of the limiting slider group 23 to form axial locking, and the guide slope is used to guide the limiting slider group 23 to retract under pressure, so as to realize pressing and locking.

[0031] Each limiting post 32 has a limiting ring 34 fixedly connected to its outer wall, and an unlocking paddle 35 slidably connected to its outer wall. The limiting ring 34 is located below the unlocking paddle 35 and is used to limit the downward limit position of the unlocking paddle 35. The unlocking paddle 35, as an intermediate transmission component for secondary pressing unlocking, works with the arc-shaped limiting block 33 to form a continuous arc-shaped guide surface, realizing the disengagement and unlocking of the limiting slider assembly 23.

[0032] like Figures 4 to 7 As shown, the grooved plate assembly 41 is snapped onto the top of the support frame 11, and the bottom of the grooved plate assembly 41 is provided with a snap-fit ​​groove, which is used to snap and fix it onto the top crossbeam of the support frame 11. Threaded posts 42 are symmetrically rotatably connected inside the grooved plate assembly 41, and several sets of rectangular slider assemblies 43 are symmetrically slidably connected inside the grooved plate assembly 41. Both threaded posts 42 are threadedly connected inside the rectangular slider assemblies 43.

[0033] It should be noted that the transmission belt 45 is connected to the outer walls of the two threaded posts 42, and a rotating handle 44 is fixedly connected to the outer wall of one of the threaded posts 42. When the rotating handle 44 is rotated, the two threaded posts 42 are driven to rotate synchronously through the transmission belt 45, which in turn drives each set of rectangular slider groups 43 to translate synchronously, thereby realizing the synchronous adjustment of the spacing between fixed points.

[0034] The top opening size of the positioning cylinder 31 is matched with the cross-sectional size of the positioning block 21. After the positioning block 21 is inserted into the positioning cylinder 31, the top inner wall of the positioning cylinder 31 and the outer wall of the positioning block 21 form a sliding seal fit, which can prevent dust and rainwater from entering the interior.

[0035] When installing the photovoltaic panel 12, first rotate the handle 44. This drives the two threaded posts 42 to rotate synchronously via the transmission belt 45, which in turn drives the rectangular slider groups 43 to move the top positioning cylinder 31 synchronously. Adjust the spacing between the fixed points to fit the size of the photovoltaic panel 12. Align the positioning block 21 at the bottom of the photovoltaic panel 12 with the positioning cylinder 31 and press it down. The limiting slider group 23 is squeezed and retracted by the arc-shaped limiting block 33. After passing the arc-shaped limiting block 33, it pops out. With the push force of the second reset spring group 36, the limiting slider group 23 comes into contact with the bottom surface of the arc-shaped limiting block 33 to form a lock, completing the quick installation.

[0036] When disassembling, press the photovoltaic panel 12 downward again. The limiting slider group 23 moves downward and contacts the unlocking paddle 35, causing the unlocking paddle 35 to move upward and disengage from the limiting ring 34. After stopping the pressing, the second reset spring group 36 pushes the positioning block 21 upward. The unlocking paddle 35 and the arc-shaped limiting block 33 together form an arc-shaped guide surface, guiding the limiting slider group 23 to retract and disengage, completing the quick disassembly.

[0037] After the photovoltaic panel 12 is installed, the second reset spring assembly 36 can absorb vibration energy and buffer external impact loads; the positioning block 21 is inserted into the positioning cylinder 31 to form a seal, preventing dust and rainwater from entering.

[0038] Based on the above embodiments, the following is the complete working process and working principle of the above embodiments: Spacing adjustment steps When photovoltaic panels 12 of different sizes and specifications need to be installed, rotate the handle 44. Rotating the handle 44 will drive one of the threaded posts 42 to rotate. The two threaded posts 42 are synchronously driven by the transmission belt 45, so that the two threaded posts 42 rotate at the same speed and in the same direction. During the rotation of the threaded column 42, the threaded transmission drives each set of rectangular sliders 43 to move synchronously along the inside of the groove plate 41. The rectangular sliders 43 synchronously drive the positioning cylinder 31 at its top and the matching fixing and unlocking components to move synchronously, thereby adjusting the lateral spacing between each set of fixing and unlocking components so that the spacing of the positioning cylinder 31 matches the arrangement spacing of the positioning block 21 at the bottom of the photovoltaic panel 12, thus achieving installation adaptation of photovoltaic panels 12 of different sizes. Since the photovoltaic panels 12 installed in the same row are usually of the same size, the synchronous adjustment of each group of rectangular sliders 43 can complete the spacing adjustment of the fixed points of the entire row at one time, with high adjustment efficiency; multiple spacing adjustment components can be arranged on the support frame 11, corresponding to multiple rows of photovoltaic panels 12 of different sizes, to meet the needs of mixed installation of photovoltaic arrays of multiple specifications.

[0039] By setting an adjustable spacing structure, rotating the handle 44 can synchronously adjust the spacing of each group of rectangular sliders 43, thereby driving the top fixed unlocking component to adjust the spacing synchronously. It can adapt to the installation requirements of photovoltaic panels 12 of different shapes and sizes, has strong versatility, and can meet the needs of mixed installation of multiple specifications of photovoltaic modules and subsequent replacement and upgrade.

[0040] Installation Lock Steps When installing the photovoltaic panel 12, align the four positioning blocks 21 at the bottom of the photovoltaic panel 12 with the corresponding positioning cylinders 31 below, press down on the photovoltaic panel 12, and let the positioning blocks 21 slide into the positioning cylinders 31 along the arc-shaped limiting block 33 and the limiting post 32. During the downward movement of the positioning block 21, the end of the limiting slider assembly 23 inside it first contacts the top guide slope of the arc-shaped limiting block 33. Under the pressure of the slope, the limiting slider assembly 23 retracts into the limiting groove 22, while simultaneously compressing the first return spring assembly 24. After the limiting slider assembly 23 has completely passed the arc-shaped limiting block 33, the first return spring assembly 24 elastically extends, pushing the limiting slider assembly 23 outward along the limiting groove 22 to reset, so that the end of the limiting slider assembly 23 moves directly below the arc-shaped limiting block 33.

[0041] Simultaneously, as the positioning block 21 descends, its bottom abuts against the abutment ring 37, pushing the abutment ring 37 to compress the second reset spring assembly 36 to store energy. When the downward pressure on the photovoltaic panel 12 stops, the second reset spring assembly 36 elastically extends, pushing the positioning block 21 upward through the abutment ring 37, causing the top surface of the limiting slider assembly 23 to tightly abut against the horizontal bottom surface of the arc-shaped limiting block 33, forming an axial locking mechanism, thus achieving rapid fixation of the photovoltaic panel 12. The entire installation process only requires one press to complete the locking, eliminating the need to tighten bolts and nuts, improving the efficiency of photovoltaic panel installation.

[0042] Second press to unlock and disassemble When the photovoltaic panel 12 needs to be disassembled, press the photovoltaic panel 12 down again. The four positioning blocks 21 continue to slide synchronously into the positioning cylinder 31. The limiting slider group 23 moves down synchronously with the positioning blocks 21 and gradually contacts the unlocking lever 35. The unlocking lever 35 is axially limited by the lower limiting ring 34 and cannot move further down. The limiting slider group 23 is squeezed by the inclined surface of the top surface of the unlocking lever 35 and retracts into the limiting groove 22, compressing the first return spring group 24. When the limiting slider group 23 has completely passed the unlocking lever 35, the first return spring group 24 elastically extends and pushes the limiting slider group 23 out. The bottom surface of the limiting slider group 23 abuts against the bottom surface of the unlocking lever 35, causing the unlocking lever 35 to slide upward along the outer wall of the limiting post 32, so that the unlocking lever 35 is released from the contact of the limiting ring 34.

[0043] Simultaneously, as the positioning block 21 continues to descend, it compresses the second reset spring assembly 36 again via the contact ring 37. At this point, the pressure on the photovoltaic panel 12 stops, and the second reset spring assembly 36 elastically extends and releases stored energy, pushing the positioning block 21 upward via the contact ring 37. The positioning block 21 then drives the unlocking lever 35 to move upward synchronously via the limit slider assembly 23. When the unlocking lever 35 moves upward to contact the bottom surface of the arc-shaped limiting block 33, the unlocking lever 35 and the arc-shaped limiting block 33 together form a continuous arc-shaped guide surface. Under the continuous pushing force of the second reset spring group 36, the limiting slider group 23 retracts into the limiting groove 22 along the arc-shaped guide surface and compresses the first reset spring group 24, and finally completely passes over the arc-shaped limiting block 33, so that the positioning block 21 is dislodged from the positioning cylinder 31, and the photovoltaic panel 12 is quickly disassembled.

[0044] By adopting a press-type quick-installation and quick-disassembly structure, when installing the photovoltaic panel 12, simply align the positioning block 21 with the positioning cylinder 31 and press down to automatically complete the locking; when disassembling, pressing down again will automatically unlock and remove the panel, eliminating the need for bolts, nuts, and fastening tools, simplifying the photovoltaic panel installation and disassembly steps, reducing on-site installation time, and lowering labor installation costs.

[0045] Shock absorption and cushioning protection effect After the photovoltaic panel 12 is installed and fixed, the positioning block 21 is inserted into the positioning cylinder 31. The second reset spring group 36 continuously applies an elastic pushing force to the positioning block 21 through the abutment ring 37, so that the limiting slider group 23 and the arc-shaped limiting block 33 are in a tight abutment and locked state. When the photovoltaic panel 12 is subjected to external vibration forces such as wind vibration and equipment resonance, the second reset spring group 36 can absorb vibration energy through elastic deformation and buffer the impact load transmitted to the photovoltaic panel 12. When subjected to external loads such as wind vibration and equipment resonance, the second reset spring group 36 can absorb vibration energy through elastic deformation and buffer the impact load, reduce problems such as hidden cracks in the panel and loose bolts caused by rigid connection, and improve the operational stability of the photovoltaic module.

[0046] Dustproof sealing enhancement effect After the photovoltaic panel 12 is installed, the positioning block 21 is inserted into the positioning cylinder 31, and the top opening of the positioning cylinder 31 is filled and sealed by the positioning block 21, forming a sliding seal. This structure can effectively prevent external dust, rainwater, and debris from entering the positioning cylinder 31, avoiding the internal springs and sliding components from jamming and failing due to dust accumulation and corrosion, ensuring long-term stable and reliable locking and unlocking functions, reducing the frequency of maintenance in harsh outdoor environments, and adapting to the long-term outdoor operation conditions of photovoltaic power stations.

[0047] This device adopts a purely mechanical press-type quick-installation and quick-disassembly structure. Installation and disassembly require no additional tools; the photovoltaic panel 12 can be installed and removed simply by pressing once to lock and pressing twice to unlock. Compared to traditional bolt and nut fixing methods, this reduces on-site installation time and labor costs. The adjustable spacing structure can accommodate photovoltaic panels 12 of various sizes and specifications, offering strong versatility and meeting the needs of mixed installations of different photovoltaic module models and future upgrades and replacements. It also integrates shock absorption, buffering, and dustproof sealing functions, balancing ease of installation with operational reliability, and is suitable for long-term stable operation under complex outdoor conditions in photovoltaic power plants.

[0048] Meanwhile, the entire device is a purely mechanical linkage structure, without electrical components or sensor parts, making it simple and reliable with a low failure rate. It also has good outdoor high temperature resistance and corrosion resistance, low maintenance costs, and can stably adapt to the long-term operation requirements of photovoltaic power stations.
