Description

Technical Field

[0001] The utility model relates to the field of photovoltaic modules, in particular to a photovoltaic module fixing device. Background Art

[0002] Photovoltaic power generation will remain a key development industry for the next few years, and even decades. With the increasing diversity of photovoltaic applications, photovoltaic greenhouses have become a common form of photovoltaic power generation. These greenhouses often use steel pipe purlins, requiring photovoltaic modules to be installed using either clamps or plates. Furthermore, to maximize power generation, the modules in these greenhouses are often tilted at around 20 degrees. If the clamps become loose, the modules can slide downward, potentially damaging them.

[0003] When using conventional aluminum alloy pressing blocks, the gaps between components are too large and waterproofing is difficult to handle; when using steel bent pressing plates, it is impossible to prevent the components from sliding down due to loosening of the pressing blocks.

[0004] Therefore, a mounting and fixing structure is needed that is both convenient and waterproof and can prevent the pressing block from loosening and the assembly from sliding down. Utility Model Content

[0005] In response to the problems existing in the prior art, the present invention provides a photovoltaic greenhouse component fixing device, which has solved at least one of the above technical problems.

[0006] The technical solution of the utility model is: a photovoltaic greenhouse assembly fixing device, comprising a connector for connecting the frame and purlin of the photovoltaic assembly, characterized in that the connector is a pressing block;

[0007] The pressing block comprises a horizontally arranged first fixing portion, an upwardly inclined first bending portion, a downwardly extending second bending portion, and a horizontally arranged second fixing portion from the side adjacent to the frame to the side away from the frame;

[0008] The first fixing portion is provided with a waist-shaped hole for passing a bolt, and the pressing block is connected to the frame of the photovoltaic module and the purlin through the bolt;

[0009] The second fixing portion is provided with mounting holes arranged side by side, and the mounting holes are used to pass through the two branches of the U-shaped bolt. The bottom of the U-shaped bolt passes through a limiting plate, and the bottom of the U-shaped bolt is threadedly connected with a locking nut. The U-shaped bolt and the limiting plate form a clamping member for clamping the purlin.

[0010] The pressing block structure of the utility model greatly improves the connection strength between the frame of the photovoltaic module and the purlin, can not only press the photovoltaic module tightly but also prevent the module from sliding down when the inclination angle is large.

[0011] Further preferably, a strip-shaped groove is provided at the bottom of the first fixing portion.

[0012] Increase friction to facilitate pressing the frame of photovoltaic modules.

[0013] Further preferably, a strip-shaped groove is formed on the top of the first fixing portion, and the head of the bolt is embedded in the strip-shaped groove;

[0014] The bottom of the strip-shaped groove is provided with the waist-shaped hole.

[0015] Improve the anti-loosening property of bolts.

[0016] Further preferably, the cross section of the head of the bolt is a regular hexagon;

[0017] The spacing between the opposite sides of the regular hexagon matches the spacing between the opposite sides of the strip-shaped grooves.

[0018] Further preferably, a sealant waterproof structure is sandwiched between the frames of adjacent photovoltaic modules.

[0019] Further preferably, the second bending portion is arranged vertically;

[0020] It also includes a vertical water guide trough, which includes a horizontally arranged trough bottom and side walls located on both sides of the trough bottom. The trough bottom is clamped between the frame and the purlin, and the side walls are located in the area between the first bending portion and the second bending portion.

[0021] This fixing structure is also applicable to structures with water guide grooves.

[0022] Further preferably, the bottom surface of the first fixing portion is higher than the bottom surface of the second fixing portion.

[0023] Further preferably, the purlin is a hollow steel tube with a C-shaped cross section.

[0024] Compared to existing technologies, this device offers the following advantages: it can both hold photovoltaic modules in place and prevent them from sliding down at high tilt angles, thus reducing the risk of module sliding down at high tilt angles. When the module tilt angle is relatively small, this device can also be used for module installations with water guide channels. This device's advantages include addressing the issue of module sliding down at high tilt angles and its high versatility. BRIEF DESCRIPTION OF THE DRAWINGS
