[0002] Solar photovoltaic panels are a type of power generation device that generates direct current when exposed to sunlight. They are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Since there are no moving parts, they can operate for long periods of time without causing any loss. Simple photovoltaic cells can provide energy for watches and computers, while more complex photovoltaic systems can provide lighting for houses and power the grid.

[0003] In the prior art, when a solar photovoltaic panel malfunctions, the generated voltage will fluctuate, which will greatly affect the power supply quality. In order to ensure the stability of the solar photovoltaic panel, an isolated DC / DC converter will be installed to dynamically adjust the power supply voltage of the solar photovoltaic panel and achieve the purpose of stably transmitting voltage to users.

[0004] However, traditional isolated DC / DC converters are mainly fixed to solar photovoltaic panels using screws during installation. However, when they need to be disassembled for inspection, multiple sets of bolts need to be turned, and the tools may accidentally touch other precision parts while turning, which may cause other problems and is inconvenient.

[0027] When the isolated DC / DC converter 5 needs to be installed during use, first pull the pull plate 12 to move the guide rod 11 outward, then place the isolated DC / DC converter 5 in the positioning ring 2, and then loosen the pull plate 12 to insert the limiting rod 13 set on the inner side of the pull plate 12 into the limiting groove 3 opened on the side of the positioning ring 2. In this way, the isolated DC / DC converter 5 can be fixedly installed in accordance with the setting of the limiting rod 13 and the positioning ring 2. When the isolated DC / DC converter 5 needs to be repaired, it is more convenient to take the isolated DC / DC converter 5 out of the positioning ring 2 by simply pulling the limiting rod 13 out of the limiting groove 3. Embodiment 2

[0028] On the basis of the first embodiment, a support rod 7 is provided, one end of the support rod 7 is fixedly connected to the side of the groove 6, one end of the support rod 7 is sleeved with a nut 15, the slider 8 can slide on the support rod 7, the inner side of the snap ring 9 is provided with an anti-slip sleeve 16, the snap ring 9 is sleeved on the positioning plate 14, the snap ring 9 can limit the positioning plate 14, the positioning plate 14 is a square plate structure, one end of the positioning plate 14 is fixedly connected to the side of the vertical plate 10, and the positioning plate 14 is provided with two groups, and the two groups of positioning plates 14 are symmetrically distributed about the vertical plate 10;

[0029] During use, when the vertical plate 10 needs to be removed from the base 4, the snap ring 9 can be pulled to make the slider 8 slide on the support rod 7, so that the snap ring 9 loses its limiting effect on the positioning plate 14 and the vertical plate 10 can be taken out. The setting of the anti-slip sleeve 16 can prevent the snap ring 9 from sliding when limiting the positioning plate 14, and the setting of the nut 15 can prevent the slider 8 from detaching from the support rod 7.

When the isolated DC / DC converter 5 needs to be repaired, it is more convenient to take the isolated DC / DC converter 5 out of the positioning ring 2 by only pulling the limit rod 13 out of the limit groove 3.
