Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel installation technology, and in particular to a photovoltaic panel installation structure that is easy to install. Background Technology

[0002] With the increasing global demand for clean energy, solar energy, as an abundant and renewable energy source, has received widespread attention for its development and utilization. Photovoltaic panels, as the core component for converting solar energy into electricity, occupy a crucial position in solar power generation systems. In recent years, photovoltaic panel technology has continuously improved, with conversion efficiency gradually increasing and costs decreasing. This has led to a growing proportion of photovoltaic power generation in the energy structure, and its application scope has expanded from large-scale centralized power plants to distributed generation, building-integrated photovoltaics (BIPV), and other fields. In distributed photovoltaic power generation and BIPV applications, photovoltaic panels typically need to be installed on the roofs of various buildings. Therefore, how to efficiently, reliably, and safely fix photovoltaic panels to the roof has become a key aspect of ensuring the stable operation and long-term use of photovoltaic power generation systems. This not only relates to the performance of the photovoltaic panels themselves but also has a significant impact on the structural safety and lifespan of the building. In traditional photovoltaic panel installation methods, the support legs are usually fixed to the roof using screws. Specifically, holes are pre-drilled in the roof, and then screws are passed through the mounting holes of the support legs and screwed into the roof structure to achieve a stable connection between the support legs and the roof. However, this fixing method has many drawbacks. The process of driving in screws can damage the original structural integrity of the roof, compromising critical structural layers such as the waterproofing and insulation layers, leading to a decline in the roof's waterproofing and insulation performance. This damage can trigger a series of serious problems. For example, after the waterproofing layer is damaged, rainwater can easily seep into the roof, and long-term accumulation can cause cracks and leaks, affecting not only the normal use of the building but also potentially damaging interior decorations and equipment. Furthermore, traditional photovoltaic panel mounting brackets are typically assembled on-site using welding. On the construction site, workers need to precisely cut, align, and weld each bracket component according to design requirements. This construction method is inconvenient, inefficient, and consumes a significant amount of time and manpower. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model aims to provide a photovoltaic panel installation structure that is easy to install. This structure can avoid damage to the original roof structure, while improving installation efficiency and ensuring the stability and reliability of the installation structure.

[0004] To achieve the above objectives, this utility model proposes a convenient photovoltaic panel installation structure, including a photovoltaic panel and an installation bracket. The photovoltaic panel is fixed above the top of the installation bracket. The installation bracket includes four vertical supports arranged in a rectangle. The four vertical supports are connected into a whole by several connecting brackets. Each vertical support is equipped with a foot plate at its bottom end. The bottom surface of the foot plate is flat and is glued to the corresponding roof surface by adhesive. The bottom surface of the foot plate is provided with several holes for the adhesive to pass through and fill.

[0005] The connecting bracket includes a longitudinal diagonal brace positioned between two adjacent vertical brackets at the front and rear, and a transverse diagonal brace positioned between two adjacent vertical brackets at the left and right. Both the connecting bracket and the vertical brackets are made of channel steel. The bottom surface of the channel steel has several bolt mounting holes along its length. The slots of the two adjacent vertical brackets at the front and rear face away from each other, while the slots of the two adjacent vertical brackets at the left and right face in the same direction. Each end of the longitudinal diagonal brace is hinged to a connecting plate by a first bolt. The connecting plate has a groove-shaped structure and bolt mounting holes on its bottom surface. The connecting plates on both sides of the longitudinal diagonal brace are fitted against the corresponding two vertical brackets. On the back of the bracket, the first bolt is equipped with a nut to lock the connecting plate onto the longitudinal diagonal brace, thereby restricting the rotation of the connecting plate. The bottom surface of the connecting plate and the back of the corresponding vertical bracket are locked and fixed by a second bolt and a nut. The second bolt passes through the bolt mounting holes at the corresponding height positions on the bottom surface of the connecting plate and the back of the vertical bracket. The two ends of the back of the transverse diagonal brace are respectively attached to the back of the two corresponding vertical brackets and are locked and fixed by a third bolt and a nut. The third bolt passes through the bolt mounting holes at the corresponding length positions of the transverse diagonal brace and the corresponding height positions on the back of the vertical bracket.

[0006] In the above solution: a sand-fixing layer is applied to the roof surface corresponding to the bottom surface of the footboard. The bottom surface of the footboard is then adhered to the sand-fixing layer with adhesive, thereby fixing it to the corresponding roof surface. The sand-fixing layer effectively prevents loose particles from the roof substrate from affecting the adhesive's bonding effect, ensuring that the footboard and roof form a tightly bonded whole. This significantly improves the stability of the entire structure, reduces the risk of footboard loosening, displacement, or even detachment, and ensures the safety of the structure for long-term use.

[0007] In the above solution: the foot plate and the connecting plate have the same structure and dimensions, and the foot plate is locked and fixed to the bottom end of the corresponding vertical bracket by a fourth bolt and a nut. During the manufacturing process, the same molds and processing techniques can be used to produce the foot plate and the connecting plate, improving production efficiency and reducing production costs. During installation, construction personnel do not need to spend extra time distinguishing between the foot plate and the connecting plate.

[0008] In the above solution: two bolt mounting holes are provided at intervals along the vertical direction on the bottom surface of the connecting plate. The bottom surface of the connecting plate and the back of the corresponding vertical bracket are locked and fixed by two second bolts and nuts. Compared with a single bolt connection, the connection stability between the connecting plate and the vertical bracket is greatly increased.

[0009] In the above scheme: the connecting bracket also includes a top tie rod arranged between two adjacent vertical brackets. The top of each of the four vertical brackets is equipped with a top plate. The top plate is locked and fixed to the corresponding vertical bracket by a fifth bolt and a nut. The two ends of the back of the top tie rod are respectively attached to the bottom surface of the two corresponding top plates and locked and fixed by a fifth bolt and a nut. The photovoltaic panel is fixed on the two top tie rods, which further enhances the stability of the connection and provides a fixed point for the photovoltaic panel.

[0010] The above solution also includes a grounding wire, one end of which is grounded and the other end is welded between any two vertical supports. This helps reduce the risk of damage to photovoltaic panels, connecting supports, and other electrical equipment due to lightning strikes, and ensures the safe operation of the entire photovoltaic system.

[0011] The beneficial effects of this utility model are:

[0012] 1. By using adhesive to bond the baseboards to the roof surface, the original roof structure is not damaged by using screws for fixing. This effectively prevents problems such as cracks and leaks caused by damage to the roof structure and extends the service life of the roof.

[0013] 2. Because there are several perforations on the bottom surface of the base plate, the adhesive can overflow into the perforations during bonding due to the pressure, thereby increasing the bonding area, improving the bonding strength, and ensuring a firm connection between the base plate and the roof.

[0014] 3. The mounting bracket is made of channel steel with pre-drilled bolt holes. All components are fixed together by bolts, eliminating the need for welding on-site. This installation method is not only simple and convenient to operate, but also greatly improves construction efficiency and reduces construction time and labor costs. At the same time, the bolt connection method facilitates the disassembly and replacement of components, which is beneficial for later maintenance and repair.

[0015] 4. Several bolt mounting holes are arranged along the length of the bottom surface of the channel steel. This design allows the connection position between the connecting bracket and the vertical bracket to be flexibly adjusted according to actual needs, making it convenient to make fine adjustments according to the site conditions during installation, and improving the versatility and adaptability of the installation structure. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0017] like Figure 1 As shown, a photovoltaic panel installation structure that is easy to install mainly consists of a photovoltaic panel 1 and a mounting bracket 2, with the photovoltaic panel 1 fixed to the top of the mounting bracket 2.

[0018] The mounting bracket 2 includes four vertical brackets 21 arranged in a rectangle. The four vertical brackets 21 are connected into a whole by several connecting brackets 22. Each vertical bracket 21 is equipped with a foot plate 4 at its bottom end. The bottom surface of the foot plate 4 is flat and is glued to the corresponding roof surface with adhesive. The bottom surface of the foot plate 4 is provided with several holes for the adhesive to pass through and fill.

[0019] The connecting bracket 22 includes a longitudinal diagonal brace 221 arranged between two adjacent vertical brackets 21 at the front and rear and a transverse diagonal brace 222 arranged between two adjacent vertical brackets 21 at the left and right. Both the connecting bracket 22 and the vertical brackets 21 are made of channel steel. Several bolt mounting holes 5 are arranged along the length of the bottom surface of the channel steel. The slots of the two adjacent vertical brackets 21 at the front and rear are arranged in opposite directions, and the slots of the two adjacent vertical brackets 21 at the left and right are arranged in the same direction.

[0020] Both ends of the longitudinal diagonal brace 221 are hinged to connecting plates 6 by first bolts 7. The connecting plates 6 have a groove-shaped structure and bolt mounting holes 5 on their bottom surface. The connecting plates 6 on both sides of the longitudinal diagonal brace 221 are attached to the back of the corresponding two vertical supports 21. The first bolts 7 are equipped with nuts to lock the connecting plates 6 onto the longitudinal diagonal brace 221, thereby restricting the rotation of the connecting plates 6. The bottom surface of the connecting plates 6 and the back of the corresponding vertical supports 21 are locked and fixed by second bolts 8 and nuts. The second bolts 8 are inserted into the bolt mounting holes 5 at the corresponding height positions on the bottom surface of the connecting plates 6 and the back of the vertical supports 21.

[0021] The two ends of the back of the horizontal diagonal brace 222 are respectively attached to the back of the corresponding two vertical supports 21 and are locked and fixed by the third bolt 9 and the nut. The third bolt 9 is inserted into the bolt mounting hole 5 at the corresponding length position of the horizontal diagonal brace 222 and the corresponding height position on the back of the vertical support 21.

[0022] Ideally, a sand-stabilizing layer should be applied to the bottom surface of the corresponding footboard 4 on the roof surface. The bottom surface of footboard 4 is then adhered to the sand-stabilizing layer with adhesive, thus fixing it to the corresponding roof surface. The sand-stabilizing layer effectively prevents loose particles from the roof substrate from affecting the adhesive's bonding effect, allowing footboard 4 to form a tightly bonded whole with the roof surface. This significantly improves the stability of the entire structure, reduces the risk of footboard 4 loosening, shifting, or even falling off, and ensures the safety of the structure for long-term use.

[0023] Ideally, the foot plate 4 and the connecting plate 6 should have the same structure and dimensions, and the foot plate 4 should be locked to the bottom of the corresponding vertical bracket 21 by the fourth bolt 10 and the nut. In the manufacturing process, the same molds and processing technology can be used to produce the foot plate 4 and the connecting plate 6, which improves production efficiency and reduces production costs. During the installation process, the construction personnel do not need to spend extra time distinguishing between the foot plate 4 and the connecting plate 6.

[0024] Ideally, the bottom surface of the connecting plate 6 is provided with two bolt mounting holes 5 spaced apart along the vertical direction. The bottom surface of the connecting plate 6 and the back of the corresponding vertical bracket 21 are locked and fixed by two second bolts 8 and nuts. Compared with a single bolt connection, this greatly increases the connection stability between the connecting plate 6 and the vertical bracket 21.

[0025] Preferably, the connecting bracket 22 also includes a top tie rod 223 arranged between two adjacent vertical brackets 21. The top of each of the four vertical brackets 21 is equipped with a top plate 11. The top plate 11 is locked and fixed to the corresponding vertical bracket 21 by the fifth bolt 3 and the nut. The two ends of the back of the top tie rod 223 are respectively attached to the bottom surface of the two corresponding top plates 11 and locked and fixed by the fifth bolt 3 and the nut. The photovoltaic panel 1 is fixed on the two top tie rods 223, which further enhances the stability of the connection and provides a fixing point for the photovoltaic panel 1.

[0026] Ideally, it should also include a grounding wire, with one end grounded and the other end welded between any two vertical supports 21. This helps reduce the risk of damage to the photovoltaic panel 1, connecting support 22, and other electrical equipment due to lightning strikes, ensuring the safe operation of the entire photovoltaic system.
