Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic inverters, and more specifically, relates to an inverter installation structure with a movable display screen. Background Art

[0002] With the rapid development of photovoltaic power generation technology, as the core device for energy conversion, the operation convenience and maintenance efficiency of photovoltaic inverters directly affect the operation efficiency of the system. Traditional inverters generally adopt a fixed display screen design, and the display control device is rigidly connected to the main machine housing through bolts, resulting in the inability to adjust the position of the display screen after the device is installed, making it difficult to achieve man-machine interaction operations in narrow spaces or high-altitude operation scenarios. Especially in distributed photovoltaic projects, inverters are often installed in non-horizontal positions such as roofs and walls, and fixed display screens have problems such as limited viewing angles and difficult data reading.

[0003] In the prior art, some inverters attempt to adopt a split display screen design, but there are often problems such as complex disassembly and assembly processes and easy damage to connectors. For example: adopting a slide rail separation structure, both hands are required to operate and tools are needed to complete the disassembly of the display screen, and poor contact is likely to occur in a vibrating environment. On the other hand, traditional inverters often form a convex part on the surface of the housing to accommodate the display screen installation structure, resulting in an increase in the thickness of the inverter, which is not conducive to wall-mounted installation and deployment in narrow spaces.

[0004] Therefore, the utility model provides an inverter installation structure with a movable display screen. Summary of the Utility Model

[0005] In view of the above problems existing in the prior art, the purpose of the utility model is to provide an inverter installation structure with a movable display screen, which adopts an embedded installation structure and a 180° flip hinge cover design to achieve rapid disassembly and assembly of the display screen and the inverter and single-handed opening of the cover, facilitating remote control and maintenance, and the flush assembly structure reduces the volume of the inverter and improves the operation efficiency.

The installation groove 210 extends along the length direction of the terminal cover 200. A limiting shutter 220 extends horizontally into the installation groove 210 from the top of the side wall of the installation groove 210 in the length direction. An installation boss 310 corresponding to the installation groove 210 and the limiting shutter 220 is provided on the back of the display control device 300. The display control device 300 is embedded in the installation groove 210 and the limiting shutter 220 of the terminal cover 200 through the installation boss 310. The outer shells of the display control device 300, the terminal cover 200, and the inverter main unit 100 are flush with each other;

[0032] The terminal cover 200 rotates outward around the axis of the hinge 400 to 180° to open the inner cavity of the inverter main unit 100. A terminal interface is provided on the terminal cover 200. The display control device 300 can realize wire harness connection with the inverter main unit 100 through the terminal interface of the terminal cover 200. A wire harness buckle is provided on the inner wall of the terminal cover 200. The wire harness connected between the display control device 300 and the inverter main unit 100 is fixed by the wire harness buckle. When the terminal cover 200 is flipped or / and when the display control device 300 is separated from the inverter main unit 100, the wire harness connected between the display control device 300 and the inverter main unit 100 is fixed on the inner wall of the terminal cover 200 by the wire harness buckle.

[0033] It should be noted that: through the embedded structure of the installation boss 310 and the installation groove 210 of the present utility model, the quick disassembly and assembly of the display control device 300 and the inverter main unit 100 are realized. The inverter main unit 100 can be remotely controlled and the operation data can be viewed in the separated state, effectively solving the problem that the traditional fixed display screen is restricted by the installation environment; moreover, the terminal cover 200 is flipped 180° through the hinge 400 to expose the inner cavity of the inverter main unit 100, significantly improving the wiring / repair efficiency.
