Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0027] Example
[0028] Reference Figure 1-5 This is an embodiment of the present invention, which provides a photovoltaic inverter protection device, including,
[0029] The photovoltaic structure 100 includes a photovoltaic inverter 110, a vent 120 formed on the surface of the photovoltaic inverter 110 for heat dissipation, a mounting groove 130 formed on one side of the vent 120, a mounting frame 140 disposed inside the mounting groove 130, and a metal protective mesh 150 fixedly installed inside the mounting frame 140.
[0030] The disassembly and assembly mechanism 200 includes a quick-release component 210 for quickly disassembling and assembling the metal protective net 150, and an anti-accidental contact component 220 to prevent accidental contact with the mounting frame 140.
[0031] The quick-release component 210 and the anti-accidental contact component 220 work together to quickly disassemble the metal protective net 150, which solves the problem that the metal protective net 150 on the traditional photovoltaic inverter 110 is fixed with screws, which reduces the replacement efficiency of the metal protective net 150. This improves the replacement efficiency of the metal protective net 150 and ensures the protective effect of the metal protective net 150.
[0032] Specifically, the quick-release component 210 includes two symmetrically fixed protrusions 211 inside the mounting groove 130, a chuck 212 fixedly installed at the end of the protrusions 211, a movable ring 213 slidably installed on the surface of the protrusions 211, a reserved groove 214 opened on the surface of the mounting frame 140, two side grooves 215 opened on the inner wall of the reserved groove 214, a U-shaped spring piece 216 fixedly installed inside the side groove 215, and a sloping locking block 217 fixedly installed on the surface of the U-shaped spring piece 216 for engaging the chuck 212.
[0033] Furthermore, the surfaces of both the chuck 212 and the movable ring 213 are beveled.
[0034] The surfaces of the chuck 212 and the movable ring 213 are beveled to facilitate their use with the beveled chuck block 217.
[0035] Preferably, a retaining ring is fixedly installed on the surface of the protruding rod 211, and the retaining ring is engaged with one side of the movable ring 213.
[0036] The retaining ring is used to limit the movement of the movable ring 213 to prevent it from sliding down too much and becoming unusable with the inclined block 217.
[0037] Furthermore, the anti-accidental contact component 220 includes a spring-loaded hinge 221 rotatably mounted on the surface of the photovoltaic inverter 110, a rotating sector block 222 fixedly mounted on the surface of the spring-loaded hinge 221, a pressing wheel 223 rotatably mounted on the surface of the mounting frame 140, and a sliding surface 224 formed on the surface of the rotating sector block 222 and used in conjunction with the pressing wheel 223.
[0038] The extrusion roller 223 is engaged with the surface of the rotating sector block 222.
[0039] When the mounting frame 140 is installed inside the mounting slot 130, the extrusion wheel 223 contacts the sliding surface 224. Under the action of the sliding surface 224, the extrusion wheel 223 extrudes the rotating sector block 222, causing the rotating sector block 222 to rotate along the spring-loaded hinge 221 until the extrusion wheel 223 moves into the storage slot, causing the extrusion wheel 223 to separate from the sliding surface 224. Under the action of the spring-loaded hinge 221, the rotating sector block 222 rotates and engages the extrusion wheel 223 inside the storage slot, thus providing double protection for the mounting frame 140 and preventing wild animals from accidentally touching the mounting frame 140 and causing the metal protective net 150 to be disassembled.
[0040] Specifically, the photovoltaic inverter 110 has a storage groove on its surface that communicates with the mounting groove 130, and the extrusion wheel 223 is located inside the storage groove.
[0041] The compression wheel 223 is stored in a storage slot, allowing it to move to the plane of the sliding surface 224, whereby the sliding surface 224 can engage and limit the compression wheel 223.
[0042] Furthermore, several push plates 160 are elastically installed inside the mounting slot 130. The push plates 160 maintain elastic force on the mounting frame 140. The surface of the photovoltaic inverter 110 is fixedly mounted with a mounting hoop 170 by a connecting rod. The mounting hoop 170 is used to fix the inverter onto the bracket.
[0043] The push plate 160 is fixedly installed inside the mounting groove 130 by a spring. The cooperation between the spring and the push plate 160 can maintain the elasticity of the mounting frame 140. When the metal protective net 150 is replaced, the mounting frame 140 and the metal protective net 150 can be ejected from the mounting groove 130 for easy replacement.
[0044] When replacing the metal protective mesh 150, first rotate the rotating sector block 222 to open the storage slot. Then press down on the mounting frame 140. The mounting frame 140 moves the inclined plate block 217 inside the reserved slot 214. When the inclined plate block 217 contacts the movable ring 213, it is squeezed by the movable ring 213, causing the inclined plate block 217 to retract into the side slot 215 until the inclined plate block 217 moves to the inclined plate of the movable ring 213. Under the action of the spring and the push plate 160, the mounting frame 140 is popped open from the inside of the mounting groove 130. The movable ring 213 is moved by the inclined block 217 to fit against the chuck 212. Under the action of the inclined surface of the movable ring 213, the inclined block 217 is moved along the inclined surface and into the inside of the side groove 215. The inclined block 217 then disengages from the surface of the chuck 212. At this time, the mounting frame 140 and the metal protective net 150 pop out from the inside of the mounting groove 130, completing the disassembly of the metal protective net 150.
[0045] The new mounting frame 140 and metal protective mesh 150 are installed inside the mounting groove 130. The mounting frame 140 is aligned with the inside of the mounting groove 130 and pressed down. The extrusion wheel 223 contacts the sliding surface 224. Under the action of the sliding surface 224, the extrusion wheel 223 extrudes the rotating sector block 222, causing the rotating sector block 222 to rotate along the spring-loaded hinge 221 until the extrusion wheel 223 moves into the inside of the receiving groove, causing the extrusion wheel 223 to separate from the sliding surface 224. Under the action of the spring-loaded hinge 221, the spring-loaded hinge 221 returns to its original position. The rotating sector block 222 rotates and engages the compression wheel 223 inside the storage slot. At the same time, the inclined surface of the chuck 212 compresses the inclined block 217, causing the inclined block 217 to be stored inside the side slot 215. The U-shaped spring 216 is in a compressed state. When the inclined block 217 moves to the plane of the chuck 212, the U-shaped spring 216 releases its elasticity, popping the inclined block 217 open and engaging it on the plane of the chuck 212, thus completing the replacement of the mounting frame 140 and the metal protective net 150.
[0046] In summary, the quick-release component 210 and the anti-accidental contact component 220 work together to quickly disassemble the metal protective net 150, solving the problem that the metal protective net 150 on the traditional photovoltaic inverter 110 is fixed with screws, which reduces the replacement efficiency of the metal protective net 150. This improves the replacement efficiency of the metal protective net 150 and ensures the protective effect of the metal protective net 150.
