Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic solar panel installation mechanisms, specifically a roof fixing and adjustment mechanism for photovoltaic installation. Background Technology

[0002] Solar photovoltaic (PV) systems, also known as photovoltaics, are facilities that convert solar energy into direct current (DC) electricity using the photovoltaic effect of photovoltaic semiconductor materials. The core of a PV system is the solar panel. Currently, the main semiconductor materials used for power generation include monocrystalline silicon, polycrystalline silicon, amorphous silicon, and cadmium telluride. Due to the active promotion of renewable energy applications by various countries in recent years, the PV industry has developed rapidly. PV systems can be installed on a large scale on the ground to form PV power plants, or placed on the rooftops or exterior walls of buildings to form building-integrated photovoltaics (BIPV).

[0003] Photovoltaics, as a clean energy source, has developed rapidly in recent years. Photovoltaic solar panels can generate electricity that can be connected to the grid and bring benefits to the users. However, most large rooftops of factories and other buildings are idle. During the installation of photovoltaic solar panels on factory rooftops, some factory rooftops have a natural tilt angle, so they can be laid flat without adjusting the angle. However, some factory rooftops are flat or the factory is tilted, so the photovoltaic panels receive less sunlight. Therefore, additional support and adjustment are needed for the installation. Based on this, a rooftop fixing and adjustment mechanism for photovoltaic installation is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a roof-mounted adjustment mechanism for photovoltaic installations to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a roof fixing and adjusting mechanism for photovoltaic installation, comprising a concave frame, with convex plates slidably fitted inside both ends of the concave frame, and several adjusting holes provided inside both the concave frame and the convex plates, with several adjusting pins movably inserted into the adjusting holes, two reinforcing plates fixedly installed on the top of the convex plate at the end away from the concave frame, two hinge plates one fixedly installed on the bottom of the convex plate at the end away from the concave frame, and two hinge plates two fixedly installed on the bottom of the concave frame, with hinge shafts movably fitted inside the two hinge plates two, and ring plates movably installed at both ends of the hinge shafts. A fixing bolt is fixedly installed through the inner side of the ring plate. Several insertion holes are opened inside the ring plate. Two insertion bolts are movably inserted into the insertion holes. A screw is fixedly sleeved on the outer side of the middle part of the hinge shaft. Several adjustment insertion holes are opened inside the screw. A screw cylinder is threadedly sleeved on the outer side of the bottom end of the screw. An anti-slip nut is movably placed on the top of the screw cylinder. Two adjustment pins are movably inserted into the inside of the screw cylinder. A support ring is fixedly sleeved on the outer side of the bottom end of the screw cylinder. A rubber ring is movably contacted on the top of the support ring. A support sleeve is movably sleeved on the outer side of the support ring. A fixing plate is fixedly installed on the bottom of the support sleeve.

[0006] Preferably, the adjusting holes are linearly and evenly distributed inside the concave frame and the convex plate, and the two ends of the adjusting pin are fixed to the outside of the concave frame by nuts.

[0007] Preferably, the fixing bolt is fixed through the ring plate and threaded to the interior of the hinge shaft, and the specifications and dimensions of the hinge shaft are adapted to the specifications and dimensions of hinge plate one and hinge plate two.

[0008] Preferably, the insertion holes are evenly distributed circumferentially inside the ring plate, and the insertion bolts movably pass through the insertion holes and the second hinge plate and extend to the opposite side of the second hinge plate.

[0009] Preferably, the adjusting holes are evenly distributed in a spiral pattern inside the screw, and the two adjusting pins are symmetrically and staggered inside the screw barrel. The size of the adjusting holes is adapted to the size of the adjusting pins, and the inner side of the anti-slip nut is threadedly connected to the outer side of the screw.

[0010] Preferably, the support sleeve is movably sleeved on the outside of the screw cylinder and the support ring, and the rubber ring is fixedly installed on the inside of the support sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this structure, the user lifts the photovoltaic panel that needs adjustment and fixation, places the mechanism at the raised position, and then stretches the length of the convex plate inside the concave frame to correspond with the width of the photovoltaic panel. The adjusting pin is then inserted into the adjusting hole to fix the concave frame and the convex plate. Next, the reinforcing plate is connected to the fixed position of the photovoltaic panel, and the screw and cylinder are rotated to adjust their lengths. When a suitable support angle is reached to provide a suitable tilt angle for the photovoltaic panel, the adjusting pin is inserted into the adjusting hole, and the anti-slip nut is rotated so that the anti-slip nut engages with the photovoltaic panel. The screw's threaded connection contacts the top of the screw barrel, thus achieving a double fixing effect. Before fixing the reinforcing plate to the photovoltaic panel, the position of the second hinge plate and the hinge shaft is rotated to make the top of the concave frame and the convex plate fit against the bottom of the photovoltaic panel for support. Then, the insertion bolt is inserted into the insertion hole and extends to the second hinge plate, thereby fixing the tilt angle of the hinge shaft and the second hinge plate. Finally, the expansion bolt is inserted through the fixing plate, and the hole is drilled in the top of the factory building for insertion and fixing. The overall flexibility is high, which is easy to adapt to various photovoltaic panels. It provides the function of adjusting and fixing the photovoltaic panel, and the structure is simple, portable and easy to assemble.

[0012] This utility model, through the provision of hinge plate two and hinge plate one, allows for the installation of three sets of screws and screw cylinders during adjustment. These are then installed by inserting the screws into the interior of hinge plate two and hinge plate one via the hinge shaft. Subsequently, the fixing bolts are rotated and threaded into the interior of both ends of the hinge shaft, fixing the hinge shaft to the inner side of hinge plate two and hinge plate one. This facilitates support at both ends, enables disassembly and assembly, improves efficiency, provides stable support for the whole structure, and increases practicality. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a roof fixing and adjusting mechanism for photovoltaic installation, including a concave frame 1, with convex plates 2 slidably sleeved inside both ends of the concave frame 1. Both the concave frame 1 and the convex plates 2 have several adjusting holes 3 inside, with several adjusting pins 4 movably inserted into the adjusting holes 3. Two reinforcing plates 6 are fixedly installed on the top of the convex plate 2 at the end away from the concave frame 1, and two hinge plates 5 are fixedly installed on the bottom of the convex plate 2 at the end away from the concave frame 1. Two hinge plates 14 are fixedly installed on the bottom of the concave frame 1. A hinge shaft 13 is movably sleeved inside the two hinge plates 14, and a ring plate 15 is movably installed at both ends of the hinge shaft 13. The inner... A fixing bolt 16 is fixedly installed through the side. Several insertion holes 19 are opened inside the ring plate 15. Two insertion bolts 20 are movably inserted into the insertion holes 19. A screw 7 is fixedly sleeved on the outer side of the middle part of the hinge shaft 13. Several adjustment insertion holes 21 are opened inside the screw 7. A screw cylinder 9 is threadedly sleeved on the outer side of the bottom end of the screw 7. An anti-slip nut 8 is movably placed on the top of the screw cylinder 9. Two adjustment pins 10 are movably inserted into the inside of the screw cylinder 9. A support ring 17 is fixedly sleeved on the outer side of the bottom end of the screw cylinder 9. A rubber ring 18 is movably contacted on the top of the support ring 17. A support sleeve 11 is movably sleeved on the outer side of the support ring 17. A fixing plate 12 is fixedly installed on the bottom of the support sleeve 11.

[0020] The working principle of the above technical solution is as follows: During use, the user lifts the photovoltaic panel that needs to be adjusted and fixed, places the mechanism at the raised position, and then stretches the length of the convex plate 2 inside the concave frame 1 to correspond with the width of the photovoltaic panel. The adjusting pin 4 is then inserted into the adjusting hole 3 to fix the concave frame 1 and the convex plate 2. Next, the reinforcing plate 6 is connected to the fixed position of the photovoltaic panel, and the screw 7 and screw barrel 9 are rotated to adjust their lengths. When a suitable support angle is reached to provide a suitable tilt angle for the photovoltaic panel, the adjusting pin 10 is inserted into the adjusting hole 21, and the anti-slip nut 8 is rotated to connect the anti-slip nut 8 to the threaded connection of the screw 7. Under the action of contact with the top of the screw cylinder 9, a double fixing effect is achieved. Before the reinforcing plate 6 is fixed to the photovoltaic panel, the position of the hinge plate 14 and the hinge shaft 13 is rotated to make the top of the concave frame 1 and the convex plate 2 fit against the bottom of the photovoltaic panel for support. Then, the plug bolt 20 is inserted into the plug hole 19 and extends to the hinge plate 14, thereby fixing the tilt angle of the hinge shaft 13 and the hinge plate 14. Finally, the expansion bolt is inserted through the fixing plate 12 and fixed by drilling holes in the top of the factory building. The overall flexibility is high, which is easy to adapt to various photovoltaic panels. It provides the function of adjusting and fixing the photovoltaic panel, and the structure is simple and easy to carry and assemble.

[0021] In another implementation scheme, such as Figures 1-4 As shown, the adjusting holes 3 are linearly and evenly distributed inside the concave frame 1 and the convex plate 2, and the two ends of the adjusting pin 4 are fixed to the outside of the concave frame 1 by nuts.

[0022] The adjustment hole 3 provides an insertion position for the adjustment pin 4, and the adjustment pin 4 passes through the concave frame 1 and the convex plate 2 to fix the position of the concave frame 1 and the convex plate 2, thereby increasing the adjustment convenience of the structure.

[0023] In another implementation scheme, such as Figures 2-4 As shown, the fixing bolt 16 fixes the through ring plate 15 and extends threadedly into the interior of the hinge shaft 13. The dimensions of the hinge shaft 13 are compatible with the dimensions of the hinge plate 15 and the hinge plate 24.

[0024] By using the hinge plate 2 14 and hinge plate 1 5, during adjustment, the three sets of screws 7 and screw cylinders 9 are installed by inserting them into the interior of hinge plate 2 14 and hinge plate 1 5 through hinge shaft 13. Then, the fixing bolts 16 are rotated and threaded into the interior of both ends of hinge shaft 13, fixing hinge shaft 13 to the inner side of hinge plate 2 14 and hinge plate 1 5. This facilitates support at both ends, realizes the function of disassembly and assembly, improves the efficiency of use, provides stable support for the whole, and increases practicality.

[0025] In another implementation scheme, such as Figures 2-4As shown, the insertion holes 19 are evenly distributed in a circle inside the ring plate 15, and the insertion bolts 20 move through the insertion holes 19 and the hinge plate 14 and extend to the opposite side of the hinge plate 14.

[0026] The insertion hole 19 provides a fixing point for the hinge shaft 13 and the second hinge plate 14. The insertion bolt 20 is inserted through the insertion hole 19 and the second hinge plate 14, thereby adjusting and fixing the rotation angle of the concave frame 1 and the second hinge plate 14 relative to the screw 7 and the hinge shaft 13, which increases the relative stability of the structure and facilitates adjustment and fixing.

[0027] In another implementation scheme, such as Figures 1-4 As shown, the adjusting socket 21 is evenly distributed in a spiral pattern inside the screw 7, and the two adjusting pins 10 are symmetrically and staggered inside the screw barrel 9. The size of the adjusting socket 21 is compatible with the size of the adjusting pins 10, and the inner side of the anti-slip nut 8 is threadedly connected to the outer side of the screw 7.

[0028] As the screw 7 and the screw barrel 9 rotate, the position of the adjusting socket 21 changes, causing the adjusting socket 21 to gradually correspond to the adjusting pin 10. The adjusting pin 10 is inserted into the adjusting socket 21, providing a stable fixed position for the screw 7 and the screw barrel 9, and is fixed after adjustment. The anti-slip nut 8 is threadedly connected to the screw 7, which applies a fixing effect to the top of the screw barrel 9, forming a double nut fixing anti-slip thread effect, which facilitates rotation adjustment and fixation.

[0029] In another implementation scheme, such as Figures 1-4 As shown, the support sleeve 11 is movably sleeved on the outside of the screw cylinder 9 and the support ring 17, and the rubber ring 18 is fixedly installed on the inside of the support sleeve 11.

[0030] The support sleeve 11 is sleeved on the outside of the support ring 17 and the screw barrel 9. When the screw barrel 9 is rotated, the screw barrel 9 is threadedly connected to the screw rod 7. Since the screw rod 7 is fixed by the hinge shaft 13, helical extension and contraction are realized. The support sleeve 11 provides a rotation limit position for the screw barrel 9 and the support ring 17 and is fixed by the fixing plate 12. The support ring 17 and the rubber ring 18 are squeezed to increase the friction. When no rotational force is applied, the screw barrel 9 remains stable and does not rotate, which facilitates the stable height position of the screw rod 7. It is convenient to tilt and support the photovoltaic panel according to the sunlight requirements in different seasons and to adjust the rotation, which increases the convenience of use.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
