Example

[0038] Reference Figures 1 to 5 In order to solve the above-mentioned technical problem of the complicated inverter installation structure, the utility model provides a buffer protection shell for protecting a micro inverter for a photovoltaic circuit, comprising: a protection box 1, a mounting mechanism 2 and a sealing mechanism 3. The mounting mechanism 2 is rotatably arranged at one end of the interior of the protection box 1, and is used to provide an installation space for the inverter. The sealing mechanism 3 is rotatably arranged at the other end of the interior of the protection box 1, and the sealing mechanism 3 and the mounting mechanism 2 are in a detachable connection relationship, thereby realizing a convenient installation of the inverter.

[0039] Furthermore, in this embodiment, the sealing mechanism 3 includes: a mounting frame 21 and two rotating shafts 22. The mounting frame 21 is arranged inside the protection box 1, and the interior of the mounting frame 21 is in a cavity shape, thereby providing an installation space for the inverter through the cavity inside the mounting frame 21. The two rotating shafts 22 are respectively fixedly arranged on both sides of one end of the mounting frame 21, and the ends of the two rotating shafts 22 away from the mounting frame 21 are rotatably connected to the protection box 1, thereby enabling the mounting frame 21 to rotate inside the protection box 1, and the rotating shafts 22 are provided with connecting screw holes 221.

[0040] Furthermore, in this embodiment, the sealing mechanism 3 includes: a cover plate 31, two threaded sleeves 32 and a bolt 33. One end of the cover plate 31 is rotatably disposed in the protection box 1 and away from the rotating shaft 22, so as to realize the rotation of the cover plate 31 at the end away from the rotating shaft 22 in the protection box 1. The two threaded sleeves 32 are both embedded in the other end of the cover plate 31. It should be added that when the cover plate 31 is rotated to a horizontal state, the threaded sleeve 32 and the connecting screw hole 221 on the rotating shaft 22 are on the same vertical line. The bolt 33 is threadedly disposed in the threaded sleeve 32, and one end of the bolt 33 passes through the threaded sleeve 32 and is connected to the connecting screw hole 221, thereby achieving the effect of quickly fixing the rotating shaft 22 and the mounting frame 21, so that the inverter inside the mounting frame 21 can be fixedly installed and protected.

[0041] In this embodiment, a mounting mechanism 2 and a sealing mechanism 3 are respectively provided at both ends of the protection box 1, wherein the mounting frame 21 structure in the mounting mechanism 2 can be used to place the inverter, and can rotate inside the protection box 1 through the design of the rotating shaft 22, and in the sealing mechanism 3, the cover plate 31 can also rotate inside the protection box 1, so that after the mounting frame 21 is horizontally rotated to the inside of the protection box 1, the cover plate 31 can be horizontally rotated to the top of the mounting frame 21 and sealed, and then the bolt 33 in the cover plate 31 is connected with the connecting screw hole 221 on the rotating shaft 22 to achieve the effect of quickly installing the inverter. That is, the technical problem of the complex inverter mounting structure in the prior art is solved.

[0042] It should be separately explained that the position of the connecting screw hole 221 changes with the rotation of the rotating shaft 22. When the mounting frame 21 is rotated to be placed horizontally in the protective box 1 (that is, the cavity of the mounting frame 21 is facing the cover plate 31), the connecting screw hole 221 can correspond to the threaded sleeve 32 of the cover plate 31 in the horizontal state.

[0043] Please refer to Figures 1 to 3 As shown, in this embodiment, the mounting mechanism 2 further includes: a protective plate 23 and a blocking plate 24. The protective plate 23 is fixedly arranged on one side of the mounting frame 21. The blocking plates 24 are fixedly connected to both ends of the top of the mounting frame 21. The protective plate 23 and the blocking plate 24 are designed to protect and limit the inverter from the back and side to prevent it from shaking inside the protective box 1. Among them, a heat dissipation groove 25 is opened on the protective plate 23 to realize the heat dissipation function of the inverter.

[0044] It should be added that a tightening block 4 is fixedly provided at the inner bottom of the protection box 1, and the tightening block 4 is located below the cover plate 31, wherein the tightening block 4 is designed to abut against one end of the inverter to prevent it from shaking inside the protection box 1. A rubber pad 5 is fixedly provided at the inner bottom of the protection box 1, and the rubber pad 5 is located on one side of the abutting block. This rubber pad 5 is used to protect the part of the inverter that contacts the bottom of the protection box 1, thereby increasing the protection effect of the device.

[0045] Please refer to Figure 5 As shown, in an optional embodiment, in order to facilitate the user to open the cover plate 31 , a groove 34 is provided on the surface of the cover plate 31 , and the groove 34 is located between the two threaded sleeves 32 .

[0046] In an optional embodiment, in order to facilitate annotation and marking of the inverter inside the protection box 1 , a label plate 35 is provided on the surface of the cover plate 31 .

[0047] In an optional embodiment, an interface group 6 is provided at one end of the protection box 1, and each hole in the interface group 6 is used for connection with an external cable.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
