Technical Field

[0002] Photovoltaic inverters can convert the variable DC voltage generated by photovoltaic solar panels into AC power at mains frequency, which can be fed back to the commercial power transmission system or used for off-grid power grids. Photovoltaic inverters are one of the important system balancers in photovoltaic array systems and can be used in conjunction with general AC-powered equipment.

[0003] For example, Chinese patent CN112104197B discloses a photovoltaic inverter, including a photovoltaic inverter body and a splash-proof shell, wherein the photovoltaic inverter body is fixedly mounted inside the splash-proof shell, cavities are arranged on the left and right sides inside the splash-proof shell, five No. 1 wind slots are arranged on the inner walls on both sides of the splash-proof shell, six No. 2 wind slots are arranged on the outer walls on both sides of the splash-proof shell, and six splash-proof baffles are arranged on the outer walls on both sides of the splash-proof shell. The photovoltaic inverter, by installing the splash-proof shell on the outside of the photovoltaic inverter, firstly provides a windproof and rainproof environment for the photovoltaic inverter, and secondly, ventilation design is performed on both sides of the splash-proof shell, so that the inside of the splash-proof shell can always be in a ventilation state, but under natural conditions, water will not enter the inside of the shell due to splashing, thereby creating a good use environment for the photovoltaic inverter.

The fixed door 510 is fixed to the inside of the box 509 by a fixed lock. When opening the fixed lock, a key matching the fixed lock is required.

The slide bar 505 slides upward inside the slide cylinder 506, and then the lower pressure plate 507 moves upward. Then the inverter body 2 can be disassembled for maintenance. At the same time, when the inverter body 2 is not removed, the hand wheel 512 can be continuously rotated to drive the rectangular plates 4 on the left and right sides to continue to move downward, and drive the inverter body 2 to continue to move downward, so as to lower the water level of the inverter body 2, facilitate maintenance, and improve the convenience of maintenance.

When the wind blows, the rectangular frame 801 can collect the wind blowing from the front and back of the inverter body 2. The collected wind can be filtered by setting the filter nets 803 on the front and rear sides. The wind collected on the front side of the rectangular frame 801 flows into the interior of the rectangular hollow plate 807 through the first front connecting pipe 804, the first front electromagnetic valve 805 and the second front connecting pipe 806, and then flows into the interior of the first air outlet plate 809, the second air outlet plate 810, the third air outlet plate 811 and the fourth air outlet plate 812 through the first movable pipes 813 on the left and right sides, the third movable pipes 816 on the left and right sides, the second electromagnetic valves 815 on the left and right sides and the second movable pipes 814 on the left and right sides, and then flows through the first air outlet heads on the left and right sides, which are not less than two, and the second air outlet heads on the left and right sides, which are not less than two. The wind head can assist in cooling the inverter body 2. At the same time, the wind collected on the back of the rectangular frame 801 flows to the inside of the rectangular hollow plate 807 through the first rear connecting pipe 804, the first rear electromagnetic valve 805 and the second rear connecting pipe 806, and then assists in cooling the inverter body 2. When it rains, the second electromagnetic valves 815 on the left and right sides can be closed, and the air can be discharged through the second air outlet plate 810 and the third air outlet plate 811 to assist in cooling the inverter body 2. When there is no wind, the fan 808 can be started, the first electromagnetic valve 805 can be closed, and the air outlet end of the fan 808 can transport the wind to the inside of the rectangular hollow plate 807 through the pipeline, and then flow to the inside of the first air outlet plate 809, the second air outlet plate 810, the third air outlet plate 811 and the fourth air outlet plate 812 to assist in cooling the inverter body 2 and improve the heat dissipation effect.

[0040] (3) When the inverter body 2 is fixed on the bracket, the left and right inclined rectangular clamping rods 903 can be supported by the left and right inclined support blocks 905, so that the left and right rectangular plates 4 and the inverter body 2 can be supported to improve the stability of the structure. When the inverter body 2 needs to be adjusted downward in height, the left and right annular abutment pieces 906 can be pushed in relative directions to drive the left and right inclined rectangular clamping rods 903 to move in relative directions inside the left and right rectangular grooves 901, and then the left and right annular abutment pieces 906 are rotated to make the left and right annular abutment pieces 906 abut against the side walls opposite to the inner cavity of the left and right side retaining frames 904, so that the left and right inclined rectangular clamping rods 903 can be limited and fixed, so that the opposite sides of the left and right inclined rectangular clamping rods 903 are located between the opposite sides of the left and right inclined support blocks 905, so that the left and right rectangular plates 4 can move downward inside the left and right rectangular tubes 3.

[0041] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0042] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
