Description

Technical Field

[0001] This invention relates to the field of photovoltaic-storage inverter technology, specifically to a photovoltaic-storage inverter that is easy to install. Background Technology

[0002] A photovoltaic (PV) inverter is a power electronic device that converts direct current (DC) generated by a photovoltaic (PV) power generation system into alternating current (AC) and has energy storage management functions. It uses efficient energy conversion technology to convert DC power generated by solar panels into AC power that matches the power grid. Simultaneously, it integrates a battery energy storage system to store and dispatch electrical energy. When sunlight is abundant, excess energy is stored in the battery, and the stored energy is released when sunlight is insufficient or during peak electricity demand. It supports both grid-connected and off-grid operating modes, has MPPT (Multi-Level Photovoltaic) function to optimize the output efficiency of the PV array, and a built-in intelligent management system for charge and discharge control, grid interaction, and load matching. It also features islanding protection, low-voltage ride-through, and other safety functions. It can be paired with different battery types and is widely used in residential PV energy storage, industrial and commercial energy storage, microgrids, and other fields. It has core values ​​such as improving PV self-consumption rate, peak shaving and valley filling, and emergency backup power. It is a key device for building new power systems and realizing the integration of PV, energy storage, and charging. With the development of intelligence and modularity, the new generation of products also supports advanced functions such as remote monitoring and virtual power plant participation.

[0003] However, existing photovoltaic-storage inverters require the mounting plate to be horizontally fixed to the wall using expansion screws. Workers then lift the inverter body, place the mounting block inside the support block, and then use tools to screw the screws through the support block into the mounting block to achieve the fixed installation of the inverter body. The installation process using screws is cumbersome, requiring four screws to be screwed in, which is labor-intensive, inconvenient, and inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide a photovoltaic-storage inverter that is easy to install, so as to solve the problem of the cumbersome installation process by screws mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic-storage inverter that is easy to install, comprising:

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The photovoltaic-storage inverter of this invention, by adjusting the setting of the limiting component, first installs the mounting plate horizontally on the wall using expansion screws. The turntable is rotated according to the height of the inverter body. The turntable rotates around the limiting ring, which drives the nut pair to rotate. The nut pair drives the trapezoidal lead screw and guide block to move up and down. The trapezoidal lead screw drives the connecting rod and the limiting plate to move up and down. After adjusting the height of the limiting plate, the clamping rod is held and rotated upwards around the fixing rod. After the clamping rod disengages from the groove of the limiting plate, the limiting plate is rotated to one side around the connecting rod. The operator then lifts the inverter body. After stabilizing the mounting block inside the support block, pinch the lever again and rotate it upwards around the fixing rod. Then, release the lever and, under the force of the torsion spring, rotate the lever downwards around the fixing rod, engaging the groove in the limit plate. No screws are needed to limit the inverter body; simply rotate the limit plate around the connecting rod to the upper surface of the inverter body. The operation is simple and quick. The limit plate limits the inverter body, and its height can be adjusted according to the actual height of the inverter body, making it highly practical.

[0019] (2) The photovoltaic storage inverter of this invention uses a swing cleaning component. The servo motor starts periodically, the output of the servo motor drives the drive rod to rotate, the drive rod drives the disc to rotate, the disc drives the cam to rotate, the cam drives the swing rod to swing around the shaft, the swing rod drives the brush to swing, and the brush can sweep away most of the dust inside the heat dissipation holes of the inverter body, so as to avoid the accumulation of dust inside the heat dissipation holes of the inverter body after long-term use, which would affect the normal heat dissipation of the inverter body.

A limit ring 25 is provided on the inner side of the lower part of the turntable 24, which limits the turntable 24 to rotate only around the limit ring 25, thereby driving the nut pair 23 to rotate. The upper part of the trapezoidal lead screw 21... A connecting rod 26 is fixedly connected, serving as a connection. A limiting plate 27 is connected to the upper outer wall of the connecting rod 26.

The limiting ring 25 limits the turntable 24, ensuring that the turntable 24 can only rotate around the limiting ring 25, thereby driving the nut assembly 23 to rotate.

[0037] Furthermore, the limiting plate 27 is rotatably connected to the connecting rod 26. The limiting plate 27 can rotate to one side around the connecting rod 26 without affecting the operator's ability to lift the inverter body 11 and place the mounting block 12 on the inner side of the bearing block 13. The limiting plate 27 has a groove corresponding to the size of the locking rod 30.

[0042] Working principle: First, install the mounting plate 14 horizontally on the wall using expansion screws. Then, rotate the turntable 24 according to the height of the inverter body 11. The turntable 24 rotates around the limiting ring 25, causing the nut pair 23 to rotate. The nut pair 23 then moves the trapezoidal lead screw 21 and guide block 22 up and down. The trapezoidal lead screw 21 moves the connecting rod 26 and limiting plate 27 up and down. After adjusting the height of the limiting plate 27, pinch the locking rod 30 and rotate it upwards while it is looped around the fixing rod 29. After the locking rod 30 disengages from the groove of the limiting plate 27, rotate the limiting plate 27 around the connecting rod 26 to one side. The operator then lifts the inverter body 11 and places the mounting block 12 on the support. After the inner side of block 13 is stabilized, the clamping rod 30 is pinched again and rotated upward around the fixing rod 29. The limiting plate 27 is rotated around the upper surface of the connecting rod 26. The clamping rod 30 is then released. Under the elastic force of the torsion spring 31, the clamping rod 30 rotates downward around the fixing rod 29 and engages in the groove of the limiting plate 27. The servo motor 41 starts periodically. The output end of the servo motor 41 drives the drive rod 42 to rotate. The drive rod 42 drives the disc 43 to rotate. The disc 43 drives the protruding rod 45 to rotate. The protruding rod 45 drives the swing rod 46 to swing around the shaft 47. The swing rod 46 drives the brush 48 to swing. The brush 48 can sweep away most of the dust inside the heat dissipation holes of the inverter body 11. The above is the complete working principle of the present invention.
