Abstract
The invention discloses a kind of split type Second bearing bracket component structure that wall installation is hung for photovoltaic DC-to-AC converter, including inverter upper bracket, inverter lower bracket, metope upper bracket, metope lower bracket, Second bearing screws.Inverter upper bracket and inverter lower bracket are fixed on the inverter back side in advance.Metope upper bracket and metope lower bracket are fixed on wall in advance or play the role of in the frame structure of wall.When inverter hangs wall installation, metope upper bracket first contacts with inverter upper bracket and starts to bear inverter weight.The dead side structure of the metal plate of metope upper bracket makes the metal plate seamed edge of inverter upper bracket not collide the metal plate bending radius area of metope upper bracket, avoids stress concentration.When inverter is just hung up properly, metope lower bracket is not contacted with inverter lower bracket in vertical gravity direction.The Second bearing for rotating metope lower bracket makes it be moved upwardly until contact inverter lower bracket with screw, completes entire inverter at this time and hangs wall installation process.
Description
Technical field
The invention belongs to power electronic equipment fields, are specifically related to a kind of bracket group that wall installation is hung for inverter
Part.
Background technique
Photovoltaic DC-to-AC converter existing common extension wall mode such as Fig. 3 and Fig. 4, wall hanging rack component includes inverter bracket and wall
Face bracket.Depending on the difference of inverter own wt, inverter bracket can be independent 1 (Fig. 3) or upper and lower 2 (Fig. 4).It is existing
Metope bracket be monomer structure.Such wall hanging rack component has following defect:
1) after inverter extension wall installs, metope bracket is contacted at upper and lower 2 end with inverter.According to mechanics principle, upper and lower 2
A contact point distance is bigger, then the lateral pull of the transverse pressure for descending contact point to bear and upper contact point receiving is smaller, metope branch
Frame is possible to using thinner Metal plate and smaller szie.But the bigger metope rack wheel exterior feature size of distance is bigger and then heavier
It is higher with cost.
2) metope bracket is there are metal plate bending fillet, and when inverter hangs wall installation, the metal plate seamed edge of inverter bracket can be touched
The metal plate bending radius area (9) for hitting metope bracket, causes stress to concentrate.
3) when inverter bracket is upper and lower 2, ideal extension wall state should be props up under inverter upper bracket (2) and inverter
Frame (4) contacts metope bracket in gravity vertical direction simultaneously.But because of the dimensional discrepancy when foozle and installation of sheet metal component,
Often there is no the lower part metal plates (10) in gravity vertical direction contact metope bracket for inverter lower bracket (4).Therefore, metope branch
The lower part metal plate (10) of frame does not undertake the weight of inverter, has only served the effect of limitation inverter lateral rotation.Standard
Defined 4 times of inverter weight needs all to be born by the top metal plate (11) of metope bracket, therefore the top metal plate of metope bracket
Golden (11) must be coarse thick and solid.1 connection metal plate (12) is also needed between top metal plate (11) and lower part metal plate (10), this is into one
Step increases weight and cost.
Summary of the invention
In order to overcome the shortcomings in the prior art, the present invention is intended to provide a kind of split type Second bearing wall hanging rack component,
Metope bracket still maintains small size under the premise of meeting intensity requirement, gravity vertical direction metope bracket can be reliable
Contact inverter lower bracket simultaneously undertakes weight.The metal plate seamed edge of inverter bracket will not collide the metal plate bending fillet of metope bracket
Region.
To realize above-mentioned technical purpose and the technique effect, the invention is realized by the following technical scheme:
A kind of split type Second bearing wall hanging rack component of photovoltaic DC-to-AC converter, metope bracket are split type, including on metope
Bracket and metope lower bracket；When inverter hangs wall installation, standard rule are born to ensure metope lower bracket together with metope upper bracket
4 times of fixed inverter weight, have used Second bearing screw.
The split type Second bearing wall hanging rack component, wherein the dead side structure of the metal plate of the metope upper bracket
So that the metal plate seamed edge of inverter upper bracket is not collided the metal plate bending radius area of metope upper bracket, avoids stress concentration.
The split type Second bearing wall hanging rack component, wherein the Second bearing screw is previously installed at
It on metope lower bracket but does not tighten, not in contact with inverter lower bracket when inverter is just hung up properly；Rotation Second bearing is made with screw
It is moved upwardly until contact inverter lower bracket, can ensure that metope lower bracket bears standard rule together with metope upper bracket at this time
4 times of fixed inverter weight.
Compared with prior art, present invention has an advantage that (1) bracket component overall dimension reduces；(2) bracket component is total
Body weight reduces.
The above description is only an overview of the technical scheme of the present invention, in order to better understand the technical means of the present invention,
And can be implemented in accordance with the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention and the accompanying drawings.
A specific embodiment of the invention is shown in detail by following embodiment and its attached drawing.
