Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction of photovoltaic inverters, and in particular to a noise reduction component for photovoltaic inverters. Background Art

[0002] During use, photovoltaic inverters often generate significant noise due to their complex internal circuitry and high-speed components. This not only affects the quietness of the surrounding environment but can also adversely affect the normal operation and lifespan of the equipment. Therefore, developing an efficient and stable noise reduction component is crucial for improving the performance and user experience of photovoltaic inverters.

[0003] Most photovoltaic inverter noise reduction components currently available on the market use traditional sound-absorbing materials and structures. While these components can reduce noise to a certain extent, their effectiveness is limited. Furthermore, their complex structures make installation and removal difficult, leading to high maintenance costs. Furthermore, some components suffer from poor stability and sealing, resulting in inconsistent noise reduction and difficulty meeting the requirements of photovoltaic inverters in diverse environments. Therefore, we offer a noise reduction component for photovoltaic inverters. Utility Model Content

[0021] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0022] Example

[0023] like Figures 1-4 As shown, one embodiment of the present invention proposes a noise reduction assembly for a photovoltaic inverter. This assembly aims to reduce noise generated during operation of the photovoltaic inverter through a compact and efficient structural design, while ensuring the stability and maintainability of the assembly. The noise reduction assembly primarily comprises an inverter body 1, an L-shaped sound absorbing panel 1 2, and an L-shaped sound absorbing panel 2 3. The L-shaped sound absorbing panels 1 2 and 2 3 are respectively fastened to the sides and top of the inverter body 1, forming an enveloping structure that effectively absorbs and isolates noise generated by the inverter.

[0024] To enhance noise reduction, a C-shaped retaining frame 4 is installed at the joint between L-shaped sound-absorbing panels 1 and 2, 3. T-shaped sliding strips 5 are fixedly connected to the inner wall of the C-shaped retaining frame 4. Furthermore, T-shaped grooves 6 that match the T-shaped sliding strips 5 are provided on the periphery of both panels, ensuring a tight connection between the two panels.

[0025] Furthermore, to prevent the noise reduction assembly from loosening or shifting during use, a special anti-movement structure is designed. This structure comprises a rectangular opening 7 on the side of the C-shaped retaining frame 4 and a rectangular recess 8 around the periphery of the L-shaped sound-absorbing panel 2. The inner wall of the rectangular recess 8 defines a seating recess 9, within which two sliding sleeves 10 are slidably connected, connected by overlapping sliders 11. As the sliding sleeves 10 slide within the seating recess 9, the overlapping sliders 11 also slide within the rectangular recess 8.

[0026] Among them, the upper end surface of the overlapping slider 11 is fixedly connected with a T-shaped plug-in plate 12, and the T-shaped plug-in plate 12 can be inserted into the rectangular opening 7 of the C-shaped limit frame 4 to achieve a stable connection between the L-shaped sound absorbing panel 2 and the C-shaped limit frame 4.

[0027] Furthermore, to ensure smooth insertion and removal of the T-shaped plug-in board 12 from the rectangular opening 7, a reset component is provided between the mounting groove 9 and the sliding sleeve 10. This reset component comprises a transverse rod 13 fixedly connected between the two end walls of the mounting groove 9. A spring 14 is sheathed around the outer periphery of the transverse rod 13, and the sliding sleeve 10 is slidably sheathed around the outer periphery of the transverse rod 13. When the sliding sleeve 10 is subjected to an external force, the spring 14 deforms; when the external force disappears, the spring 14 returns to its original shape, pushing the sliding sleeve 10 back into its original position, thereby driving the T-shaped plug-in board 12 into or out of the rectangular opening 7. Finally, to ensure a tight connection between the L-shaped sound absorbing panels 1 and 2, rectangular slots 16 are provided on the inner sidewalls and one end surface of the L-shaped sound absorbing panel 2, while a rectangular insert 17, which mates with the rectangular slots 16, is fixedly connected to one end surface and the inner sidewall of the L-shaped sound absorbing panel 1. When the two sound-absorbing panels are buckled together, the rectangular inserting strip 17 can be inserted into the rectangular slot 16 to achieve a stable connection between the two sound-absorbing panels.
