Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket installation technology, specifically a rooftop photovoltaic bracket that is easy to install. Background Technology

[0002] Solar photovoltaic (PV) mounting brackets are special supports designed for placing, installing, and fixing solar panels in a solar PV power generation system. They are typically made of aluminum alloy, carbon steel, or stainless steel. During manufacturing, the lengths of each component are pre-cut in the factory according to the site dimensions, and the holes are pre-drilled. The brackets are then transported to the designated location for assembly.

[0003] In existing technologies, commonly used support frames are assembled using aluminum alloy tubes fixed with bolts. The traditional assembly process involves first fixing the four sets of support legs, and then fixing the crossbeams and diagonal braces. When fixing the crossbeams and diagonal braces, manual assistance is usually used to help position them. Operators need to support the weight of the crossbeams and diagonal braces while using tools to assemble them, making the installation of photovoltaic brackets very inconvenient. In addition, roofs are divided into flat roofs and sloping roofs. Sloping roofs have a certain slope, which is not conducive to the operator's standing, further increasing the difficulty of assembly. The traditional assembly process requires manual assistance to support the crossbeams and diagonal braces, which poses high safety risks and is inefficient when working on sloping roofs. Therefore, there is an urgent need to optimize the installation process. Utility Model Content

[0004] The purpose of this utility model is to provide a rooftop photovoltaic support system that is easy to install. The support structure can be supported by a cement base, which also facilitates the reshaping of sloping roofs, ensuring stable installation of the direct structure. When installing the horizontal and diagonal structures, the correct connectors are selected for fixation, and the foldability of the horizontal and diagonal structures is utilized to connect the two ends to the connectors. This avoids the need for manual support of the horizontal and diagonal structures during installation, ensuring safety and increasing installation speed, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rooftop photovoltaic support that is easy to install, comprising: a cement base and a support structure set on the roof; the support structure includes four sets of vertical rods, two sets of horizontal rods arranged on the left and right, and two sets of diagonal rods arranged front and back, the two ends of the horizontal rods and diagonal rods are connected to the vertical rods through connectors, and the horizontal rods and diagonal rods are configured as foldable two-section structures; the connectors are fixedly connected to the vertical rods through connecting bolts; the vertical rods are installed on the cement base.

[0006] Preferably, both the crossbar structure and the diagonal bar structure include two straight bars. The bottom ends of the two straight bars facing each other are hinged together by a hinge. The top of the two straight bars are engaged with a buckle. A positioning bolt is provided on the outside of the buckle, and the thread of the positioning bolt passes through the buckle and the straight bar.

[0007] Preferably, the connector includes a fixed sleeve sleeved on the outside of the vertical rod, and a movable sleeve sleeved on the outside of the fixed sleeve sleeved on the outside of the vertical rod.

[0022] 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.

[0023] This utility model provides, for example Figures 1-5 The rooftop photovoltaic support structure shown includes: a cement base 1 mounted on the roof and a support structure; the support structure includes four sets of vertical rods 2, two sets of horizontal rods 3 arranged on the left and right, and two sets of diagonal rods 4 arranged front and back. Both ends of the horizontal rods 3 and diagonal rods 4 are connected to the vertical rods 2 via connectors 5. The horizontal rods 3 and diagonal rods 4 are designed as foldable two-section structures for easy connection with the connectors 5; the connectors 5 are fixedly connected to the vertical rods 2 via connecting bolts 6; the vertical rods 2 are mounted on the cement base 1.

[0024] By designing the crossbar structure 3 and the diagonal bar structure 4, the straight bar 7 can be folded using hinges. This not only reduces the length and facilitates handling, but also allows the movable end of the straight bar 7 to be inserted into the relatively fixed movable sleeve 52 through opening and closing. The movable sleeve 52 can be pre-installed and fixed using the fixed sleeve 51, enabling separate operation of manual support and bolt fixing. This ensures the safety of workers, simplifies the installation process, and increases the speed of photovoltaic bracket installation.

[0025] Among them, such as Figure 2-3 As shown: Both the horizontal bar structure 3 and the diagonal bar structure 4 include two straight bars 7. The bottom of the two straight bars 7 facing each other is hinged together by a hinge. The top of the two straight bars 7 is snapped with a buckle 8. A positioning bolt 9 is provided on the outside of the buckle 8, and the thread of the positioning bolt 9 passes through the buckle 8 and the straight bar 7. The two sets of straight bars 7 are hinged together by the hinge. The straight length of the two ends can be changed by folding. It is convenient to connect the horizontal bar structure 3 and the diagonal bar structure 4 with the connecting piece 5 when the positions of the two sets of connecting pieces 5 are fixed. Then, the movable end of the straight bar 7 is inserted into the movable sleeve 52 by pressing, and the two sets of straight bars 7 are kept straight. The positioning bolt 9 and the buckle 8 are used to fix the two sets of straight bars 7 together, which improves the stability of the horizontal bar structure 3 and the diagonal bar structure 4.

[0026] Furthermore, such as Figure 2 and Figure 4 As shown: Connector 5 includes a fixed sleeve 51 sleeved on the outside of the vertical rod 2. A movable sleeve 52 sleeved on the outside of the straight rod 7 is also provided on the outside of the fixed sleeve 51. The connecting bolt 6 is located on the outside of the movable sleeve 52. The connecting bolt 6 passes through the movable sleeve 52 and the fixed sleeve 51 and is threaded with a nut. By dividing connector 5 into fixed sleeve 51 and movable sleeve 52, the fixed sleeve 51 is directly sleeved on the outside of the vertical rod 2, while the movable sleeve 52 is connected to the fixed sleeve 51 by the connecting bolt 6 and thus fixes the fixed sleeve 51. The position of connector 5 can be installed in advance. This process can be completed not only on the construction site but also in advance. Then, the vertical rod 2 with connector 5 is transported to the roof, reducing the amount of on-site construction work.

[0027] Preferred, such as Figure 2 As shown: A slot 10 is provided at the end of the straight rod 7 away from the hinge. The slot 10 is engaged with the outside of the connecting bolt 6. By providing a slot 10 at the movable end of the straight rod 7, it is convenient to misalign the straight rod 7 with the connecting bolt 6 when the straight rod 7 is inserted into the movable sleeve 52. This prevents the straight rod 7 from being unable to penetrate the movable sleeve 52, which would result in the movable sleeve 52 being unable to effectively limit and fix the straight rod 7 when the connecting bolt 6 is tightened. Furthermore, it would cause uneven force on both sides of the movable sleeve 52 and the connecting bolt 6, leading to deformation. At the same time, it increases the contact area between the straight rod 7 and the movable sleeve 52, improving the stability of the connection.

[0028] It is worth noting that, such as Figure 3 As shown: A reinforcing rod 11 is slidably installed inside the straight rod 7. A guide groove 12 is opened on the opposite side of the top of the straight rod 7. A moving block 13 is fixed to the top of the reinforcing rod 11 and slidably installed in the guide groove 12. A limiting hole 14 for cooperating with the moving block 13 is opened at the top of the inner cavity of the buckle 8. A through hole for cooperating with the positioning bolt 9 is opened on the reinforcing rod 11. By inserting the reinforcing rod 11 into a set of straight rods 7, and after the two sets of straight rods 7 are aligned, the reinforcing rod 11 is transferred from one set of straight rods 7 to a position spanning the two sets. The straight rod 7 provides support at the connection point of the straight rod 7 inside, preventing the crossbar structure 3 and the diagonal bar structure 4 from deforming under stress and affecting the support capacity. At the same time, the cooperation between the movable block 13 and the guide groove 12 facilitates the movement and transfer of the reinforcing rod 11. Subsequently, the buckle 8 is provided with a limiting hole 14 that cooperates with the movable block 13 to store the movable block 13 and ensure that the buckle 8 is stably engaged with the straight rod 7. At the same time, after the buckle 8 is installed, the limiting hole 14 can restrict the sliding of the movable block 13 and the reinforcing rod 11.

[0029] In a further preferred embodiment, such as Figure 5 As shown: The cement base 1 includes a cement pile 101 and an internal steel reinforcement structure 102. A support seat 103 is welded to the top of the steel reinforcement structure 102. The top of the support seat 103 is inserted into the vertical rod 2. An installation bolt 15 is provided on the outside of the vertical rod 2. The installation bolt 15 passes through the vertical rod 2 and the support seat 103 and is threaded with a nut. Through structural analysis of the cement base 1, the steel reinforcement structure 102 not only improves the strength of the cement base 1, but also allows for pre-drilling holes in the roof, inserting the bottom of the steel reinforcement structure 102 into the holes to fix the steel reinforcement structure 102. Cement is then poured on the outside of the steel reinforcement structure 102, and the cement pile 101 is formed by the solidification of the cement. The cement pile 101 not only protects the steel reinforcement structure 102, but also prevents the drilled hole from being exposed, thus preventing rainwater infiltration. The cement base 1 needs to be made in advance, and after the support structure is processed, it can be directly connected to the vertical rod 2 through the support seat 103 and the locking of the installation bolt 15.

[0030] In addition, such as Figure 1 As shown: A support plate 16 is laid on the top of the inclined rod structure 4, and the support plate 16 is connected to the straight rod 7 by screw threads. The support plate 16 is fixed to the top of the inclined rod structure 4 by screws for laying photovoltaic panels.

[0031] In this embodiment, as Figure 4 As shown: Multiple sets of protrusions 17 are provided on the inner wall of the movable sleeve 52, and the protrusions 17 are attached to the outer side of the straight rod 7. By setting the protrusions 17, the ability of the movable sleeve 52 to restrict the straight rod 7 is increased, preventing the straight rod 7 from slipping out of the movable sleeve 52.

[0032] In practical use, the roof is measured in advance, then holes are drilled in the roof, the steel structure 102 is inserted into the holes, and then cement is poured on the outside of the steel structure 102 to form a cement pile 101. At the same time, a support seat 103 is welded to the top of the steel structure 102 to make the top of the support seat 103 horizontal.

[0033] The support structure is cut and welded in the factory to complete the processing of each component. Then the components are transported to the installation point. First, four sets of vertical rods 2 are inserted into the top of the support base 103 and fixed with mounting bolts 15 and nuts. Then, two sets of fixed sleeves 51 are put on the outside of the vertical rods 2, and the movable sleeves 52 are attached to the outside of the fixed sleeves 51. The movable sleeves 52 and fixed sleeves 51 are simultaneously fixed in the designated position of the vertical rods 2 with connecting bolts 6. At this time, the movable sleeves 52 can rotate around the connecting bolts 6.

[0034] Then, the horizontal bar structure 3 and the diagonal bar structure 4 are assembled. The horizontal bar structure 3 and the vertical bar structure 2 are folded to reduce the straight distance between the two ends of the straight bar 7. When the movable end of the straight bar 7 is less than the distance between the two sets of movable sleeves 52, the straight bar 7 is inserted into the movable sleeve 52. Then, the middle position of the horizontal bar structure 3 and the diagonal bar structure 4 is pressed so that the two sets of straight bars 7 are connected with the hinge. When the straight bar 7 is inserted into the movable sleeve 52, the slot 10 at the end of the straight bar 7 can avoid the connecting bolt 6.

[0035] After the two sets of straight rods 7 are set vertically, the moving block 13 is moved in the guide groove 12, which drives the reinforcing rod 11 to move, so that the reinforcing rod 11 spans the two sets of straight rods 7 and supports the straight rods 7 from the inside. Then, the buckle 8 is snapped into the docking point, so that the limiting hole 14 is snapped into the moving block 13, which restricts the movement of the moving block 13 and the reinforcing rod 11. Then, the buckle 8, straight rod 7 and reinforcing rod 11 are fixed with the positioning bolt 9. The remaining horizontal rod structure 3 and diagonal rod structure 4 are assembled in the same way. Finally, the connecting bolt 6 is tightened to ensure that the movable sleeve 52 limits the straight rod 7 and prevents slippage. Finally, the support plate 16 is placed on the top of the diagonal rod structure 4 and fixed with screws.

[0036] 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.
