Description

Technical Field

[0001] This utility model belongs to the field of inverter technology, and in particular relates to a modular single-phase inverter. Background Technology

[0002] An inverter is a converter that transforms DC power into AC power with fixed frequency and voltage or frequency and voltage regulation. It consists of an inverter bridge, control logic, and filter circuits.

[0003] The following problems exist in the application of single-phase inverters currently on the market: Traditional single-phase inverters are generally fixed directly with bolts when in use. When it is necessary to disassemble them, it is difficult. After disassembly, the bolts need to be unscrewed. And the bolts need to be used again when installing them next time. The frequent bolt tightening is labor-intensive, making it difficult to install and disassemble, and also inconvenient to splice. Utility Model Content

[0004] The purpose of this utility model is to provide a modular single-phase inverter to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A modular single-phase inverter includes a housing, a top plate on the top of the housing, a mounting buckle fixedly connected to the surface of the top plate, a side plate fixedly connected to the side of the housing, a shaft fixedly connected to the side of the side plate, a rotating rod sleeved on the outside of the shaft, and the rotating rod inserted into the mounting buckle.

[0006] Preferably, a circular plate is fixedly connected to the top of the rotating rod, and a pull plate is fixedly connected to the side of the circular plate.

[0007] Preferably, the side of the housing is provided with heat sinks, which are symmetrically distributed.

[0008] Preferably, a first square plate is fixedly connected to the side of the top plate, a second square plate is fixedly connected to the side of the box body, a limiting rod is fixedly connected to the bottom of the first square plate, a limiting hole is opened on the surface of the second square plate, and the limiting rod is inserted into the limiting hole.

[0009] Preferably, the side of the housing is equipped with a fan, and the number of the fans is two.

[0010] Preferably, the bottom of the enclosure is provided with a base plate, and heat dissipation holes are provided on the base plate and the surface of the enclosure.

[0011] This utility model of a modular single-phase inverter has the following advantages: The modular single-phase inverter features a top plate added to the top of the enclosure. A mounting buckle is installed on the surface of the top plate, and a side plate is installed on the side of the enclosure. A shaft is installed on the side of the side plate, and a rotating rod is sleeved on the outside of the shaft. The rotating rod is inserted into the mounting buckle. When installing the top plate, the top plate and the enclosure are aligned and positioned. Rotating the rotating rod causes it to rotate outside the shaft, engaging with the mounting buckle. This fixes the top plate to the top of the enclosure, facilitating the splicing of the top plate. During use, if internal maintenance of the inverter body is required, simply rotating the rotating rod is sufficient, making re-splicing convenient. This makes splicing relatively easy.

[0026] like Figure 1-6As shown, this utility model discloses a modular single-phase inverter, including a housing 1. A top plate 2 is provided on the top of the housing 1, with a mounting buckle 6 fixedly connected to its surface. A side plate 14 is fixedly connected to the side of the housing 1, and a shaft 11 is fixedly connected to the side of the side plate 14. A rotating rod 13 is sleeved on the outside of the shaft 11 and inserted into the mounting buckle 6. By adding a top plate 2 to the top of the housing 1, mounting buckles 6 are installed on the surface of the top plate 2, and side plates 14 are installed on the side of the housing 1. A shaft 11 is installed on the side of the side plate 14, and a rotating rod 13 is sleeved on the outside of the shaft 11 and inserted into the mounting buckle 6, when installing the top plate 2, the top plate 2 and the housing 1 are aligned, and the rotating rod 13 is rotated, causing the rotating rod 13 to rotate outside the shaft 11. The rotating rod 13 is engaged inside the mounting buckle 6, thus fixing the top plate 2 to the top of the housing 1, facilitating the splicing of the top plate 2.

[0027] A circular plate 12 is fixedly connected to the top of the rotating rod 13, and a pull plate 4 is fixedly connected to the side of the circular plate 12. By installing a circular plate 12 on the top of the rotating rod 13 and a pull plate 4 on the side of the circular plate 12, the rotating rod 13 can be easily rotated by holding the pull plate 4.

[0028] The side of the enclosure 1 is provided with heat sinks 3, which are symmetrically distributed. By installing heat sinks 3 on the side of the enclosure 1, the heat generated by the single-phase inverter can be easily dissipated from the heat sinks 3.

[0029] The top plate 2 is fixedly connected to the side of the first square plate 5, and the box body 1 is fixedly connected to the side of the second square plate 1. The bottom of the first square plate 5 is fixedly connected to the limiting rod 7. The surface of the second square plate 15 is provided with a limiting hole 16, and the limiting rod 7 is inserted into the limiting hole 16. By installing the first square plate 5 on the side of the top plate 2 and the second square plate 15 on the side of the box body 1, the limiting rod 7 is installed at the bottom of the first square plate 5, and the limiting hole 16 is provided on the surface of the second square plate 15, the top plate 2 and the box body 1 can be easily aligned by inserting the limiting rod 7 into the limiting hole 16.

[0030] Two fans 10 are provided on the side of the enclosure 1. By installing fans 10 on the side of the enclosure 1, it is convenient to blow out the heat inside.

[0031] The bottom of the enclosure 1 is provided with a base plate 9, and heat dissipation holes 8 are opened on the base plate 9 and the surface of the enclosure 1. By installing the base plate 9 at the bottom of the enclosure 1 and opening heat dissipation holes 8 on the base plate 9 and the surface of the enclosure 1, the fan 10 can blow heat out from the heat dissipation holes 8.

[0032] The working principle of this modular single-phase inverter is as follows: When using this single-phase inverter, it is first assembled. The top plate 2 and the cabinet 1 are aligned using the first square plate 5 and the second square plate 15. The limiting rod 7 is inserted into the limiting hole 16. The pull plate 4 and the circular plate 12 are held together and their rotating rod 13 is rotated, so that the rotating rod 13 rotates outside the shaft 11. The rotating rod 13 is engaged inside the mounting buckle 6. At this time, the top rod can be fixed to the top of the cabinet 1, which facilitates the splicing of the top plate 2. After the splicing is completed, the bottom plate 9 and the heat sink 3 are installed on the cabinet 1. After installation, the wiring is connected and it can be used. At this time, the fan 10 can be turned on. The fan 10 blows the heat inside the cabinet 1 out through the heat dissipation holes 8 opened on the bottom plate 9 and the side of the cabinet 1. The heat sink 3 can provide double heat dissipation, which improves the heat dissipation effect.
