Description

Technical Field

[0001] This invention relates to the field of photovoltaic module installation technology, and in particular to a fixing device for ultra-thin frameless solar photovoltaic modules. Background Technology

[0002] Ultra-thin frameless solar photovoltaic modules are devices that generate electricity when exposed to sunlight, composed of thin solid photovoltaic cells made of semiconductor materials. During the construction of steel structure buildings, to improve the sun protection and corrosion resistance of the roof, it is preferable to add photovoltaic modules to the top of the steel structure roof panels. This not only enhances the performance of the steel structure building but also enables the utilization of solar energy.

[0003] Existing ultra-thin frameless solar photovoltaic module fixing devices have the following shortcomings: they are not targeted enough. For example, when installing on the top of a steel structure roof panel, there are joint gaps between the roof panels, and the existing devices cannot make good use of these joints. As a result, they cannot achieve the dual purpose of covering the roof joint gaps and reinforcing the fixing of the photovoltaic modules.

[0004] Therefore, a mounting device for ultra-thin frameless solar photovoltaic modules is disclosed to overcome the above-mentioned shortcomings. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a fixing device for ultra-thin frameless solar photovoltaic modules.

[0006] The present invention is achieved by the following technical solution: a fixing device for ultra-thin frameless solar photovoltaic modules, comprising: a U-shaped block, two base blocks fixedly installed on the top of the U-shaped block, and a top cover plate installed on the top of the two base blocks; two fastening mechanisms, both of which are set on the top cover plate, and the fastening mechanisms are used to clamp and fix the ultra-thin frameless solar photovoltaic modules; and an installation mechanism located below the U-shaped block, and the installation mechanism is used to connect and fix with the roof panel joint.

[0007] Both base blocks are L-shaped, and the distance between the two base blocks is smaller than the distance between the inner surfaces of the U-shaped blocks.

[0008] Through the above technical solution, the "L"-shaped base block is used to abut against one side of the photovoltaic panel to facilitate the installation of the photovoltaic panel, and the above-mentioned spacing setting can facilitate the fastening mechanism to fasten the photovoltaic panel.

[0009] The fastening mechanism includes a first knob, a fastening screw, and a locking pin. The first knob is located above the top cover plate. The fastening screw is fixedly installed at the bottom of the first knob. The bottom end of the fastening screw extends into the U-shaped block and is rotatably connected to the top cover plate. The locking pin is threaded onto the fastening screw.

[0010] With the above technical solution, when installing the photovoltaic panel, the end of the photovoltaic panel is inserted between the base block and the top cover plate. Then, the first knob is gradually tightened until the base block and the top cover plate reliably clamp and fix the photovoltaic panel.

[0011] The width of the locking pin is greater than the distance between the two base blocks, and the locking pin is adapted to the U-shaped block.

[0012] By using the above technical solution, the width setting of the locking pin can ensure that the locking pin is always located in the cavity of the U-shaped block, so as to achieve reliable fixation of the ultra-thin frameless photovoltaic panel through the base block and the top cover plate.

[0013] The mounting mechanism includes a first side block, a second side block, four mounting holes, two positioning bolts, and a mounting slot. The first side block is located below the U-shaped block, and the second side block is located on one side of the first side block. The four mounting holes are respectively opened on the first side block and the second side block. The two positioning bolts pass through the four mounting holes respectively. Both positioning bolts are threaded with washers and nuts. The mounting slot is opened on the outer wall of one side of the first side block.

[0014] Through the above technical solution, by setting up the first side block, the second side block, the mounting hole, the positioning bolt, and the mounting slot, during installation, the joint of the roof panel is located in the mounting slot at the bottom of the first side block. Then, the positioning bolt is tightened so that the first side block and the second side block clamp the joint of the roof panel. This achieves both reinforcement and shielding of the roof panel joint, and also enables the subsequent photovoltaic panel to shield the joint gap.

[0015] As a further improvement to the above scheme, both the first and second side blocks are "L" shaped structures, and the ground planes of the first and second side blocks are located on the same horizontal plane.

[0016] Through the above technical solution, the first and second side blocks of the "L"-shaped structure can increase the area fixed to the roof panel and improve the stability of the fixing device.

[0017] As a further improvement to the above scheme, two triangular positioning blocks are fixedly installed on one outer wall of the second side block, and two triangular positioning grooves are opened on one outer wall of the first side block. One side of each of the two triangular positioning blocks extends into the two triangular positioning grooves and is adapted to each of the two triangular positioning grooves.

[0018] Through the above technical solution, the triangular positioning block and the triangular positioning groove can be set to quickly position the first side block and the second side block on the roof panel joint, thereby improving installation efficiency.

[0019] As a further improvement to the above solution, lower protective pads are fixedly installed on both base blocks, and two upper protective pads are fixedly installed on the bottom of the top cover plate. Anti-slip grooves are provided on the side of the two lower protective pads and the two upper protective pads that are close to each other.

[0020] Through the above technical solution, the ultra-thin frameless photovoltaic panel is relatively thin and the surface is made of glass. The lower and upper protective pads are set to protect the two sides of the ultra-thin frameless photovoltaic panel to buffer the impact of the tightening force of the fastening screw on the ultra-thin frameless photovoltaic panel.

[0021] To solve the above-mentioned technical problems, the present invention provides a fixing device for ultra-thin frameless solar photovoltaic modules, comprising two telescopic mechanisms, both of which are mounted on a U-shaped block. Each telescopic mechanism includes a mounting plate, two inclined support rods, a telescopic seat, a telescopic plate, a storage shell, two first fixing blocks, two second fixing blocks, multiple connecting rods, a slotted groove, a drive motor, a first threaded rod, and an internally threaded slider. The mounting plate is fixedly mounted on one outer wall of the U-shaped block, and both inclined support rods are fixedly mounted on one outer wall of the mounting plate. The telescopic seat is fixedly mounted on one end of the two inclined support rods, and the telescopic plate is located on one side of the telescopic seat. The storage shell is fixed... Installed on one outer wall of the telescopic base, two first fixing blocks are fixedly installed inside the telescopic plate and the storage shell respectively, and two second fixing blocks are slidably installed inside the telescopic plate and the storage shell respectively. Multiple connecting rods are arranged between the telescopic plate and the storage shell, with two adjacent connecting rods hinged together. The corresponding connecting rods are hinged to the two first fixing blocks and the two second fixing blocks respectively. A strip groove is opened on one inner wall of the storage shell, and the drive motor is fixedly installed in the strip groove. The first threaded rod is fixedly installed on the output shaft of the drive motor, and the internal threaded slider is threadedly sleeved on the first threaded rod. One side of the internal threaded slider is fixedly connected to the corresponding second fixing block.

[0022] The above technical solution allows for the adjustment of the support mechanism's position by setting up a telescopic mechanism, enabling it to move to the lower center of the photovoltaic panel.

[0023] As a further improvement to the above solution, two support mechanisms are provided on both telescopic plates. The support mechanism includes a strip plate, a support plate, a buffer pad, a second threaded rod, and a second knob. The strip plate is fixedly installed on one outer wall of the telescopic plate, the support plate is slidably installed on one outer wall of the telescopic plate, the buffer pad is fixedly installed on the top of the support plate, the second threaded rod is rotatably installed on the bottom of the support plate, the second threaded rod passes through the strip plate and is threadedly connected to the strip plate, and the second knob is fixedly installed on the bottom of the second threaded rod.

[0024] The above technical solution, with its supporting mechanism, can provide support to the center of the bottom of the photovoltaic panel, thereby improving its stability during rainy or windy weather.

This achieves both reinforcement and shielding of the joint of the roof panel, and also enables the subsequent photovoltaic panel to shield the joint gap.

[0040] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0041] First embodiment:

[0042] The fixing device for ultra-thin frameless solar photovoltaic modules in this embodiment includes: a U-shaped block 1, with two base blocks 2 fixedly installed on the top of the U-shaped block 1, and a top cover plate 3 installed on the top of the two base blocks 2; two fastening mechanisms, both of which are set on the top cover plate 3, and the fastening mechanisms are used to clamp and fix the ultra-thin frameless solar photovoltaic modules; and an installation mechanism, which is located below the U-shaped block 1 and is used to connect and fix with the roof panel joint.

[0043] Both base blocks 2 are L-shaped structures, and the distance between the two base blocks 2 is smaller than the distance between the inner surfaces of the U-shaped block 1.

[0044] Through the above technical solution, the "L"-shaped base block 2 is used to abut against one side of the photovoltaic panel to facilitate the installation of the photovoltaic panel, and the above-mentioned spacing setting can facilitate the fastening mechanism to fasten the photovoltaic panel.

[0045] The fastening mechanism includes a first knob 4, a fastening screw 5, and a locking pin 6. The first knob 4 is located above the top cover plate 3. The fastening screw 5 is fixedly installed at the bottom of the first knob 4. The bottom end of the fastening screw 5 extends into the U-shaped block 1 and is rotatably connected to the top cover plate 3. The locking pin 6 is threaded onto the fastening screw 5.

[0046] With the above technical solution, when installing the photovoltaic panel, the end of the photovoltaic panel is inserted between the base block 2 and the top cover plate 3. Then, the first knob 4 is gradually tightened until the base block 2 and the top cover plate 3 reliably clamp and fix the photovoltaic panel.

[0047] The width of the locking pin 6 is greater than the distance between the two base blocks 2, and the locking pin 6 is adapted to the U-shaped block 1.

[0048] By using the above technical solution, the width setting of the locking pin 6 can ensure that the locking pin 6 is always located in the cavity of the U-shaped block 1, so as to achieve reliable fixation of the ultra-thin frameless photovoltaic panel through the base block 2 and the top cover plate 3.

[0049] The mounting mechanism includes a first side block 7, a second side block 8, four mounting holes 9, two positioning bolts 10, and a mounting slot 11. The first side block 7 is located below the U-shaped block 1, and the second side block 8 is located on one side of the first side block 7. The four mounting holes 9 are respectively opened on the first side block 7 and the second side block 8. The two positioning bolts 10 pass through the four mounting holes 9 respectively. Both positioning bolts 10 are threaded with washers and nuts. The mounting slot 11 is opened on the outer wall of one side of the first side block 7.

[0050] Through the above technical solution, by setting up the first side support block 7, the second side support block 8, the mounting hole 9, the positioning bolt 10 and the mounting slot 11, during installation, the joint of the roof panel is located in the mounting slot 11 at the bottom of the first side support block 7. Then, the positioning bolt 10 is tightened so that the first side support block 7 and the second side support block 8 clamp the joint of the roof panel. This achieves both reinforcement and shielding of the roof panel joint, and also enables the subsequent photovoltaic panel to shield the joint gap.

[0051] Both the first side block 7 and the second side block 8 are "L" shaped structures, and the ground planes of the first side block 7 and the second side block 8 are located on the same horizontal plane.

[0052] Through the above technical solution, the first side block 7 and the second side block 8 of the "L"-shaped structure can increase the area fixed to the roof panel and improve the stability of the fixing device.

[0053] Two triangular positioning blocks 12 are fixedly installed on one side of the outer wall of the second side block 8. Two triangular positioning grooves 13 are opened on one side of the outer wall of the first side block 7. One side of each of the two triangular positioning blocks 12 extends into the two triangular positioning grooves 13 and is adapted to each of the two triangular positioning grooves 13.

[0054] Through the above technical solution, the triangular positioning block 12 and the triangular positioning groove 13 can be set to quickly position the first side upright block 7 and the second side upright block 8 on the roof panel joint, so as to improve the installation efficiency.

[0055] Lower protective pads 14 are fixedly installed on both base blocks 2, and two upper protective pads 15 are fixedly installed on the bottom of the top cover plate 3. Anti-slip grooves 16 are provided on the side of the two lower protective pads 14 and the two upper protective pads 15 that are close to each other.

[0056] Through the above technical solution, the ultra-thin frameless photovoltaic panel is relatively thin and the surface is made of glass. The lower protective pad 14 and the upper protective pad 15 are set to protect the two sides of the ultra-thin frameless photovoltaic panel to buffer the effect of the pulling force of the fastening screw 5 on the ultra-thin frameless photovoltaic panel.

[0057] The implementation principle of the first embodiment of this application is as follows:

[0058] During installation, the roof panel joint is positioned within the mounting slot 11 at the bottom of the first side block 7. The positioning bolts 10 are then tightened to clamp the roof panel joint between the first side block 7 and the second side block 8. This reinforces and shields the roof panel joint, while allowing the joint to be bent at an angle according to the installation environment. It also provides a bidirectional shielding effect for the subsequent photovoltaic panels on the joint gaps. When installing the photovoltaic panels, the ends of the panels are inserted between the base block 2 and the top cover plate 3, and then gradually installed by the first screw... Tighten the screw 5 by turning the knob 4 until the base block 2 and the top cover plate 3 reliably clamp and fix the photovoltaic panel. Since the ultra-thin frameless photovoltaic panel is relatively thin and the surface is made of glass, the lower protective soft pad 14 and the upper protective soft pad 15 are set to protect the two sides of the ultra-thin frameless photovoltaic panel to buffer the pulling force of the fastening screw 5 on the ultra-thin frameless photovoltaic panel. In addition, the anti-slip groove 16 can increase the friction between the lower protective soft pad 14 and the upper protective soft pad 15 and the ultra-thin frameless photovoltaic panel, thereby improving the reliability of the fixation.

One side of the internal threaded slider 28 is fixedly connected to the corresponding second fixing block 23.

[0063] The above technical solution allows for the adjustment of the support mechanism's position by setting up a telescopic mechanism, enabling it to move to the lower center of the photovoltaic panel.

[0064] Each of the two telescopic plates 20 is equipped with two support mechanisms, each including a strip plate 29, a support plate 30, a buffer pad 31, a second threaded rod 32, and a second knob 33.

[0065] The above technical solution, with its supporting mechanism, can provide support to the center of the bottom of the photovoltaic panel, thereby improving its stability during rainy or windy weather.
