Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module technology, and in particular relates to a photovoltaic module assembly-type snap-fit ​​connection frame structure. Background Technology

[0002] Photovoltaic modules, also known as solar panels, are the core equipment of a solar power generation system. They consist of multiple solar cells connected in series or parallel to increase voltage and current. The surface of a photovoltaic module is covered with a transparent glass layer, which protects the cells while allowing sunlight to pass through. The back of the photovoltaic module has a backsheet and a junction box for support and electrical connection. When sunlight shines on the surface of the photovoltaic module, photons interact with silicon atoms, exciting electrons and generating current. This current is then transmitted or stored through special equipment. Photovoltaic modules are usually installed in outdoor environments. The cells on the top of the photovoltaic modules are easily damaged by severe weather or other factors such as wind, rain, dust, and hail, which reduces the area of ​​the module that absorbs sunlight and thus reduces the power generation efficiency of the module. To address this, we propose a modular snap-fit ​​frame structure for photovoltaic modules. Utility Model Content

[0003] The purpose of this utility model is to provide a photovoltaic module assembly-type snap-fit ​​connection frame structure. By setting a protective mechanism, specifically, the photovoltaic panel is placed at the center of the top of the base plate, and then two support blocks are installed on the front and rear sides of the top of the base plate respectively. Then, the two square plates are pulled away from each other, causing the square plates to move the pins outwards. Next, the top plate is rotated to the front, so that the U-shaped protrusion contacts the rectangular protrusion. Then, the square plates are released, allowing the pins to move via a spring and insert into the rectangular protrusion, fixing the base plate and top plate together. This protects the top of the photovoltaic panel, making the top cells less susceptible to physical damage from external factors, maintaining the stability of the solar absorption area of ​​the module, and thus ensuring the module's power generation efficiency. This solves the problem that existing photovoltaic modules, usually installed outdoors, are easily damaged by harsh weather conditions such as wind, rain, dust, hail, or other factors, reducing the solar absorption area and thus lowering the module's power generation efficiency.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a photovoltaic module assembly snap-fit ​​connection frame structure, including a photovoltaic panel, and further comprising: A protective mechanism is disposed on the outside of the photovoltaic panel, and the protective mechanism supports the photovoltaic panel from the bottom; A frame mechanism is provided inside the protective mechanism, which protects the photovoltaic panel from the corner.

[0019] A specific application of this embodiment is as follows: In use, firstly, the two protrusions 311 are installed on the left and right sides of the top of the base plate 211, respectively. Then, the photovoltaic panel 1 is placed at the top center of the protrusions 311. Next, the slider 313 is aligned with the slide rail 312. Then, the trapezoidal corner protectors 314 are moved so that the trapezoidal corner protectors 314 on the front and the trapezoidal corner protectors 314 on the back are brought closer to each other along the slide rail 312. Finally, the irregularly shaped slider 3172 is aligned with the irregularly shaped slide rail 3171. The protruding plate 3151 drives the insert block 3152 to move, and inserts the insert block 3152 into the spring piece 3162 of the outer shell 3161. The spring piece 3162 locks the insert block 3152 through elastic deformation, thereby fixing the trapezoidal corner protector 314 and the protruding block 311 together. Then, the protruding block shaped insert 3182 is aligned with the shaped slot 3181 and inserted into the shaped slot 3181, so that the support block 212 is connected to the trapezoidal corner protectors 314 on the left and right sides. Next, the U-shaped protrusion 214 is installed at the center of the front of the base plate 211. Then, the two pull rods 222 are pulled away from each other, causing them to move away from each other along the slot 221. This will move the square plate 2171 installed at the bottom, causing the two square plates 2171 on the left and right sides to move the pins 2172 away from each other and compress the spring 2173. Then, the top plate 213 is rotated to the front, so that the top plate 213 closes the top of the photovoltaic panel 1. When the top plate 213 rotates, it will drive 315 to rotate, causing the rectangular protrusion 215 to be inserted into the U-shaped notch at the top of the U-shaped protrusion 214 under the action of the U-shaped protrusion 214. Then, the pull rod 222 is released, so that the square plate 2171 stops compressing the spring 2173. Then, under the action of the spring 2173, the pin 2172 is inserted into the rectangular protrusion 215. Through the connection between the U-shaped protrusion 214 and the rectangular protrusion 215, Next, the top plate 213 is connected to the bottom plate 211. Then, bolts are passed through the internal threads at the center of several protrusions on the outer surfaces of the bottom plate 211 and the top plate 213 to further fix the bottom plate 211 and the top plate 213 together. The center of the top plate 213 is a transparent polycarbonate plate, which has high strength and excellent impact resistance, far exceeding ordinary glass and acrylic. It can resist the impact of hail and sandstorms, avoiding damage to the surface of the module. It also has good weather resistance, resisting ultraviolet radiation and extreme temperature changes, preventing aging, discoloration or deformation caused by long-term outdoor exposure, ensuring the stability and transparency of the protective shell. Furthermore, it has strong waterproof performance and corrosion resistance, preventing rainwater from seeping in and salt spray from corroding, protecting the electrical safety of the photovoltaic module. Finally, the high transparency ensures that light can pass through fully without affecting the power generation efficiency. At the same time, its lightweight characteristics facilitate installation, and its thermal stability helps heat dissipation and extends the service life of the module. Finally, connect the electromagnetic wire 322 to the photovoltaic panel 1 and the junction box, then insert the electromagnetic wire 322 into the bottom center of the upper buckle 323, and then fix the electromagnetic wire 322 to the bottom center of the upper buckle 323 by rotating the lower buckle 324. Then, use screws to lock the upper buckle 323 and the lower buckle 324. When photons in sunlight hit the surface of the photovoltaic panel 1, they will excite electron movement and generate current. Then, through several cells connected in series or parallel in the photovoltaic panel 1, the voltage and current are increased, so that the electrical energy meets the output requirements. Then, the electrical energy is output to the outside through the electromagnetic wire 322 installed at the bottom of the photovoltaic panel 1.
