The plug-in block 5 is slidably connected to the fixing block 6 via the slide grooves, so that the user can quickly install and remove the installation frame 3 from the shell 2.

[0028] In addition, a rotating rod 7 is rotatably installed inside the installation frame 3, and a limiting plate 8 is fixedly installed on the top of the rotating rod 7. A first installation groove is opened inside the installation frame 3, and the rotating rod 7 is rotatably connected to the installation frame 3 through the first installation groove. The number of the rotating rod 7 and the limiting plate 8 are both four.

[0029] It should be noted that the waterproof solar inverter is equipped with a snap-on limit assembly, which makes it easy to quickly install the moisture absorbing block 4 in the installation frame 3. After the moisture absorbing block 4 has been used for a long time, it is easy to disassemble the moisture absorbing block 4 from the shell 2, thereby improving the effect and quality of the use of the moisture absorbing block 4, reducing the situation where water vapor extends to the inside of the shell 2 through the ventilation holes, and increasing the service life of the internal components of the shell 2.

[0030] Specifically, when the moisture absorbing block 4 of the waterproof solar inverter needs to be replaced, the threaded connection between the bolt 15 and the base 1 is released, the shell 2 is removed from the base 1, and then the limit of the plug-in block 5 by the fixing component is released, and then the plug-in block 5 is moved out from the inside of the fixing block 6, and then the limit plate 8 is rotated 180 degrees by the rotating rod 7 to release the limit on the moisture absorbing block 4, so that the user can take out the moisture absorbing block 4 from the inside of the installation frame 3 and replace the moisture absorbing block 4, thereby improving the effect and quality of the use of the moisture absorbing block 4, reducing the situation where water vapor extends to the inside of the shell 2 through the ventilation holes, and improving the service life of the internal components of the shell 2.

[0031] In this embodiment, the fixing assembly includes a telescopic spring 9 fixedly installed inside the fixing block 6. The insides of the two fixing blocks 6 are both provided with a mounting groove, and the telescopic spring 9 is fixedly connected to the fixing block 6 through the mounting groove.

[0032] A movable plate 10 is fixedly installed on the top of the telescopic spring 9, and a movable groove is opened inside the fixed block 6. The movable plate 10 is slidably connected with the fixed block 6 through the movable groove, providing a guide for the movement of the limit rod 13, making the movement of the limit rod 13 more convenient. A vertical block 11 is fixedly installed on the top of the movable plate 10, a connecting plate 12 is fixedly installed on one side of the vertical block 11, and a pull ring is installed on the top of the vertical block 11.

[0033] Among them, a limiting rod 13 is fixedly installed at the bottom of the connecting plate 12, extension holes are opened inside the two fixed blocks 6, and plug-in holes are opened on the tops of the two plug-in blocks 5.

[0034] In addition, a heating fan 14 is provided inside the shell 2, bolts 15 are threadedly connected on both sides of the base 1, a through hole is provided inside the shell 2, and a threaded hole is provided inside the base 1. The bolts 15 are threadedly connected to the base 1 through the through hole and the threaded hole, so that the shell 2 can be fixed to the base 1 by the bolts 15.

[0035] It should be noted that the waterproof solar inverter further limits and fixes the installation frame 3 by installing a fixing component, thereby improving the installation stability of the moisture absorbing block 4 and thus facilitating the improvement of the use quality of the moisture absorbing block 4 .

[0036] Specifically, the waterproof solar inverter pulls the two vertical blocks 11 through the pull ring, drives the two telescopic springs 9 to stretch, drives the movable plate 10 to move, makes the two connecting plates 12 move synchronously, and then drives the limit rod 13 to move upward, releases the limit on the plug-in block 5, so that when the user replaces the moisture absorption block 4, it is convenient for the user to take out the moisture absorption block 4 from the shell 2.

[0037] The working principle of the above embodiment is:

[0038] (1) When the moisture absorbing block 4 of the waterproof solar inverter needs to be replaced, the threaded connection between the bolt 15 and the base 1 is released, the shell 2 is removed from the base 1, and then the limit of the plug-in block 5 by the fixing assembly is released. Then the plug-in block 5 is moved out from the inside of the fixing block 6, and then the limit plate 8 is rotated 180 degrees by the rotating rod 7 to release the limit on the moisture absorbing block 4, thereby facilitating the user to take out the moisture absorbing block 4 from the inside of the installation frame 3 and replace the moisture absorbing block 4, thereby improving the effect and quality of the moisture absorbing block 4, reducing the situation where water vapor extends into the inside of the shell 2 through the ventilation holes, and increasing the service life of the internal components of the shell 2.

[0039] (2) The waterproof solar inverter pulls the two vertical blocks 11 through the pull ring, drives the two telescopic springs 9 to stretch, drives the movable plate 10 to move, makes the two connecting plates 12 move synchronously, and then drives the limit rod 13 to move upward, releases the limit on the plug-in block 5, so that when the user replaces the moisture absorption block 4, it is convenient for the user to take out the moisture absorption block 4 from the shell 2.
