Description

Technical Field

[0001] This technical solution relates to the field of photovoltaic bracket installation technology, and specifically refers to a photovoltaic bracket installation block. Background Technology

[0002] A photovoltaic (PV) bracket is a support structure designed to place, install, and fix solar panels in a solar photovoltaic power generation system, thereby securing and supporting the PV modules.

[0003] For example, Chinese patent CN201887680U discloses a C-shaped steel fixing bracket for easy installation of solar photovoltaic panels. The front support connector is bolted to the front fixed support, the rear fixed support is bolted to the rear foundation, the rear column is bolted to the rear support connector, and the rear column connector is bolted to the rear column. The longitudinal and transverse tracks and columns all use a structure connected by bolts and connectors. C-shaped steel is often used as purlins; see [reference needed]. Figure 4 and Figure 5 The photovoltaic module frame includes a C-shaped steel 100 and a photovoltaic module frame 200. The C-shaped steel 100 includes a straight section 101 and side sections 102 integrally connected to opposite sides of the straight section 101. Each side section 102 is provided with a folded edge 103, and the folded edges 103 on both sides face each other. The straight section 101 is provided with a first connection hole 300, and the photovoltaic module frame 200 is provided with a second connection hole 400.

[0004] In existing fixed photovoltaic support systems, photovoltaic modules are generally directly bolted together. To meet the adaptation requirements of different installation locations, such as the aforementioned solar photovoltaic panel "C"-shaped steel fixing bracket, a large number of bolt holes are opened in each C-shaped steel frame according to the installation location. During construction, it is necessary to select the corresponding purlins according to the hole positions for assembly, which is prone to construction errors. Moreover, such dense openings increase the input of steel cutting and drilling processes, resulting in a cumbersome and time-consuming processing process and a higher overall cost. Summary of the Invention

[0005] This technical solution aims to improve the problem of high overall processing costs caused by densely packed holes in existing bolted connections by providing an installation pressure block for photovoltaic brackets.

[0006] The purpose of this technical solution is achieved as follows:

[0007] A mounting block for a photovoltaic bracket, used to connect a photovoltaic module frame and a C-shaped steel, includes a main body with at least one mounting hole. The main body has a snap-fit ​​side plate and a locking side plate arranged opposite each other, forming a snap-fit ​​cavity between the snap-fit ​​side plate and the locking side plate. The snap-fit ​​side plate extends with a snap-fit ​​portion bent toward the snap-fit ​​cavity, and the snap-fit ​​portion has a snap-fit ​​groove. When the snap-fit ​​groove is engaged with the folded edge of the C-shaped steel, the main body of the block is engaged with the end of the C-shaped steel through the snap-fit ​​cavity, so that the locking side plate is correspondingly limited to the corresponding outer wall of the C-shaped steel.

[0008] Through the above technical solution, when a photovoltaic bracket mounting block is in normal use, the snap-fit ​​groove on one side is first fitted with the folded edge of the C-shaped steel to form a hook-and-loop fit. Then, the main body of the block is pressed down, and after being installed obliquely, it abuts against the outer surface of the edge section of the C-shaped steel. At the same time, the locking side plate moves accordingly to the corresponding outer wall of the C-shaped steel. At this time, the end of the C-shaped steel is limited to the snap-fit ​​cavity between the two side plates, which initially restricts the swing of the main body of the block on the C-shaped steel. The main body of the block is further restricted from moving along the C-shaped steel by welding, bolting, or snap-fitting. After aligning the second connection hole on the photovoltaic module frame with the mounting hole, fasteners are inserted for connection, thereby realizing the rapid and stable installation of the photovoltaic module frame, the mounting block, and the C-shaped steel. The operation is simple and convenient, simplifies the construction process, reduces construction errors caused by multi-hole design, and reduces processing costs.

[0009] Preferably, the mounting holes are provided in multiple locations, and the mounting holes are used to align with the connection holes on the photovoltaic module frame one by one.

[0010] The above technical solution allows for the stable installation of photovoltaic module frames of different sizes and positions by varying the number of mounting holes, thus broadening the applicability of the pressure block body and improving its practicality.

[0011] Preferably, the plurality of mounting holes are arranged at intervals along the through direction of the snap-fit ​​cavity.

[0012] The above technical solution arranges multiple mounting holes at intervals along the through direction of the snap-fit ​​cavity, and the width of the pressure block body in this direction is increased accordingly to provide more support area and improve the stability of the installation connection.

[0013] Preferably, the locking side plate has a positioning hole, which is used to align with the connection hole of the C-shaped steel.

[0014] The above technical solution involves aligning the mounting hole with the connecting hole on the C-shaped steel and then connecting them with fasteners (such as dovetail self-tapping screws), thereby limiting the swaying and displacement of the pressure block body along the length of the C-shaped steel and improving installation stability.

[0015] Preferably, the main body of the pressing block has an integrally extended portion, and the extended portion has the mounting hole.

[0016] By using the above technical solution, the mounting holes are concentrated on the extended portion of the main body of the pressure block, thereby separating the main body of the pressure block from the C-shaped steel and the photovoltaic module frame installation area. This optimizes the structural stress distribution, provides more installation foundations, facilitates installation, and enhances the reliability and durability of the overall structure.

[0017] Preferably, the span between the snap-fit ​​side plate and the locking side plate is adapted to the width of the C-shaped steel section.

[0018] By using the above technical solution, the span distance between the two side plates is precisely matched, reducing the assembly gap between the two side plates and the corresponding side wall of the C-shaped steel after installation, reducing the lateral shaking and twisting of the pressure block on the C-shaped steel, and improving the installation stability and resistance to lateral loads.

[0019] Preferably, the span between the bottom of the snap-fit ​​groove and the bottom of the snap-fit ​​cavity is adapted to the width of the folded edge of the C-shaped steel.

[0020] The above technical solution achieves a tight fit and clamping of the main body of the pressure block with the folded edge of the C-shaped steel, reduces the assembly gap between the folded edge and the snap-fit ​​cavity, reduces the vertical swaying and torsion of the pressure block on the C-shaped steel, and further improves the installation stability and resistance to lateral loads.

[0021] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0022] 1. This technical solution uses the snap-fit ​​groove and the hook-fitting of the C-shaped steel folded edge to insert the C-shaped steel into the snap-fit ​​cavity through side pressure. The snap-fit ​​side plate and the locking side plate limit the swing, realizing the quick pre-positioning and stable connection between the pressure block body and the C-shaped steel. The photovoltaic module frame is fixed through the mounting hole through the connector, realizing the quick and stable installation of the three. It is easy to operate, requires fewer holes, and reduces costs.

[0023] 2. This technical solution uses positioning holes on the side plate of the clamping plate. After aligning the mounting holes with the connecting holes on the C-shaped steel, fasteners are inserted for connection, thereby limiting the swaying and displacement of the main body of the pressure block along the length of the C-shaped steel and improving installation stability.

[0033] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0034] Example:

[0035] See Figure 1 and Figure 2 A mounting block for a photovoltaic bracket is used to connect a photovoltaic module frame 200 and a C-shaped steel 100 respectively. It includes a main body 1, which is generally in the form of a sheet-like plate. The main body 1 has a snap-fit ​​side plate 11 and a locking side plate 12 integrally extended on its side. The snap-fit ​​side plate 11 and the locking side plate 12 are relatively parallel and are thin-walled side plates. A snap-fit ​​cavity 2 is formed between the two side plates, and the span distance between their relative inner side walls matches the width of the two side segments 102 of the C-shaped steel 100, so as to ensure that during installation, the corresponding ends of the C-shaped steel 100 can be stably limited and clamped in the snap-fit ​​cavity 2.

[0036] The snap-fit ​​side plate 11 has a snap-fit ​​part 3, which is bent and formed relative to the snap-fit ​​side plate 11 towards the snap-fit ​​cavity 2. The snap-fit ​​part 3 has a snap-fit ​​groove 4, the groove opening is set towards the bottom of the snap-fit ​​cavity 2, and the span distance between the bottom of the groove and the bottom of the snap-fit ​​cavity 2 matches the width of the folded edge 103 of the C-shaped steel 100. The groove shape and size of the snap-fit ​​groove 4 are adapted to the thickness and size of the folded edge 103, so that after the end of the folded edge 103 is inserted into the snap-fit ​​groove 4, the entire folded edge 103 can be stably inserted and fit into the snap-fit ​​cavity 2, forming a reliable hook and fit.

[0037] See Figure 2 and Figure 4 The locking side plate 12 has a positioning hole 6, and the straight section 101 of the C-shaped steel 100 has a corresponding connecting hole 300. When the pressure block body 1 is installed, the mounting hole 5 is aligned with the connecting hole 300, and the fastener is passed through the mounting hole 5 and the connecting hole 300 to connect. The fastener is preferably a dovetail self-tapping screw to realize the connection and positioning between the C-shaped steel 100 and the pressure block body 1.

[0038] See Figure 2 and Figure 6 The pressure block body 1 has an extension portion 7, which is located on one side of the snap-fit ​​side plate 11 and extends outward integrally. The extension portion 7 has at least one mounting hole 5. When the photovoltaic module frame 200 is installed on the pressure block body 1, it is connected to the connection hole 400 by a connector passing through the corresponding mounting hole 5. The connector is preferably a bolt and nut, so as to achieve the fixed installation of the pressure block body 1 and the photovoltaic module frame 200. Figure 1 As shown, the single-hole pressure block body 1 is usually installed between the outer edge of the photovoltaic module frame 200 and the C-shaped steel 100.

[0039] See Figure 3 , Figure 5 , Figure 7 and Figure 8 The mounting holes 5 can be provided in multiple ways. In this embodiment, two mounting holes 5 are shown. The two mounting holes 5 are located on the extension part 7 and are arranged at intervals along the through direction of the snap-fit ​​cavity 2. When the two photovoltaic module frames 200 are placed side by side, the double-hole pressure block body 1 is usually installed in the middle of the C-shaped material, between the two adjacent photovoltaic module frames 200, and can connect the two frames.

[0040] Compared to the pressure block body 1 with a single hole, the pressure block body 1 with two mounting holes 5 has a larger width. The larger size of the pressure block body 1 can obtain more bearing area. When two adjacent photovoltaic module frames 200 are installed on the pressure block body 1, sufficient support is obtained. The two mounting holes 5 can be aligned one-to-one with the two connecting holes 400. By connecting the corresponding mounting holes 5 and connecting holes 400 through the connectors, the pressure block body 1 and the two photovoltaic module frames 200 can be fixedly installed. By selecting different models of pressure block bodies 1, the required installation effect and method can be freely adjusted.

[0041] The specific work process of this plan is as follows:

[0042] This technical solution involves fitting the snap-fit ​​groove 4 on one side with the folded edge 103 of the C-shaped steel 100 to form a hook-and-fit engagement. Then, the pressure block body 1 is pressed laterally. After being inserted obliquely, the pressure block body 1 abuts against the outer surface of the edge segment 102 of the C-shaped steel 100. Simultaneously, the locking side plate 12 moves accordingly to the corresponding outer wall of the C-shaped steel 100. The positioning hole 6 aligns with the first connection hole 300 for fasteners to pass through and connect. At this time, the end of the edge segment 102 of the C-shaped steel 100 is confined within the snap-fit ​​cavity 2 between the two side plates, initially restricting the lateral swing and axial movement of the pressure block body 1 on the C-shaped steel 100. After aligning the second connection hole 400 on the photovoltaic module frame 200 with the mounting hole 5, fasteners are inserted for connection. This achieves rapid and stable installation of the photovoltaic module frame 200, the mounting pressure block, and the C-shaped steel 100. The operation is simple and convenient, simplifying the construction process, reducing construction errors due to multi-hole design, and reducing processing costs.
