Description

Technical Field

[0001] The utility model relates to the field of inverter-related products, and specifically relates to a string inverter mounting bracket. Background Technique

[0002] The string inverter is based on the modular concept. Each photovoltaic string (1-5kw) is connected to an inverter. It has maximum power peak tracking at the DC end and is connected in parallel at the AC end to the grid. It has become the most popular inverter in the international market. Its advantages are that it is not affected by the differences between modules in the string and shading, and at the same time reduces the mismatch between the optimal operating point of the photovoltaic module and the inverter, thereby increasing the power generation. These technical advantages not only reduce the system cost but also increase the system reliability.

[0003] However, it is very difficult to adjust the height of the existing inverter according to the actual use situation after it is installed and fixed on the wall. It needs to be removed and reinstalled by drilling holes on the wall again. The operation is cumbersome and time-consuming, and it has defects. Content of the Utility Model

A traction plate is threadedly sleeved on the lead screw. A limiting plate is fixedly connected to the front surface of the traction plate. A bearing plate is fixedly connected to the bottom of the limiting plate. The inverter body is arranged on the bearing plate. Vertical plates are fixedly connected to both ends of the bearing plate. A push plate is slidably inserted into the vertical plate. A clamping plate is fixedly connected to one end of the push plate. A moving plate is fixedly connected to the other end of the push plate. A threaded rod is threadedly inserted into the bottom end of the moving plate. One end of the threaded rod is rotatably connected to the vertical plate.

[0006] Preferably, the bottom end of the lead screw penetrates through one of the connecting plates and extends downward. A handle is fixedly connected to the extended end of the lead screw.

[0007] Preferably, a rotating block is fixedly connected to the end of the threaded rod away from the vertical plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Please refer to Figures 1-3, an embodiment provided by the present utility model: a string inverter mounting bracket, including two symmetrically arranged mounting frames 1 and an inverter body 2. The two mounting frames 1 are fixed by two symmetrically arranged connecting plates 3. A lead screw 4 is rotatably connected between the two connecting plates 3. A traction plate 5 is threadedly sleeved on the lead screw 4. Specifically, when the lead screw 4 rotates on the connecting plate 3, the traction plate 5 threadedly sleeved on the lead screw 4 will drive the limiting plate 6 to move, thereby realizing the height adjustment of the installation of the inverter body 2; a limiting plate 6 is fixedly connected to the front surface of the traction plate 5, and a bearing plate 7 is fixedly connected to the bottom of the limiting plate 6. The inverter body 2 is arranged on the bearing plate 7. Vertical plates 8 are fixedly connected to both ends of the bearing plate 7. A push plate 9 is slidably inserted into the vertical plate 8. One end of the push plate 9 is fixedly connected to a clamping plate 10, and the other end of the push plate 9 is fixedly connected to a moving plate 11. A threaded rod 12 is threadedly inserted into the bottom end of the moving plate 11. One end of the threaded rod 12 is rotatably connected to the vertical plate 8. Specifically, the bearing plate 7 supports the inverter body 2. By rotating the threaded rod 12 to rotate on the vertical plate 8, when the threaded rod 12 rotates, the moving plate 11 threadedly sleeved thereon will move accordingly, thereby causing the push plate 9 to move on the vertical plate 8. At this time, the push plate 9 will push the clamping plate 10 to realize the clamping and fixing of the inverter body 2.

[0019] In this embodiment, the bottom end of the lead screw 4 penetrates through one of the connecting plates 3 and extends downward. A handle 13 is fixedly connected to the extended end of the lead screw 4, which is convenient for rotating the lead screw 4; a rotating block 14 is fixedly connected to the end of the threaded rod 12 far from the vertical plate 8, which is convenient for rotating the threaded rod 12; a limiting groove is provided on the front surface of the mounting frame 1. A sliding rod 15 is fixedly connected in the limiting groove. A sliding block 16 is slidably sleeved on the sliding rod 15. The sliding block 16 is fixedly connected to the limiting plate 6. The connection of the sliding block 16 and the limiting plate 6 slides on the sliding rod 15 to realize the sliding support at both ends; assembly plates 17 are fixedly connected to the outer walls of the upper and lower ends of the mounting frame 1. Assembly holes are provided on the assembly plates 17, which is convenient for fixing the mounting frame 1; multiple anti-slip lines are provided on the side of the clamping plate 10 close to the inverter body 2, which are arranged obliquely to increase the stability during clamping.

[0020] Working principle: The mounting frame 1 is fixed in the specified installation area. During installation, the bearing plate 7 is used to support the inverter body 2. By rotating the threaded rod 12 to rotate on the vertical plate 8, when the threaded rod 12 rotates, the moving plate 11 threadedly sleeved thereon will move accordingly, thereby causing the push plate 9 to move on the vertical plate 8. At this time, the push plate 9 will push the clamping plate 10 to realize the clamping and fixing of the inverter body 2. The height adjustment of the installation of the inverter body 2 can be realized by rotating the lead screw 4 to rotate on the connecting plate 3. At this time, the traction plate 5 threadedly sleeved on the lead screw 4 will drive the limiting plate 6 to move.
