Description

Technical Field

[0001] This utility model relates to the field of inverter test rack technology, and more specifically, to a multi-type inverter mounting test rack. Background Technology

[0002] Currently, inverter testing requires a dedicated space with wall space for either flat placement or wall mounting to meet testing needs. However, this causes significant damage to the walls and wastes space. Placing inverters on a flat surface not only occupies space but also poses operational inconveniences and risks of electric shock. Furthermore, if multiple inverters are installed for testing simultaneously, each inverter conservatively requires approximately 10 wires (two battery power lines, two AC mains lines, two photovoltaic power lines, one grounding wire, one communication line, and two load power lines), leading to messy wiring and potential safety hazards. Therefore, we have proposed an improvement: a multi-type inverter mounting test rack. Summary of the Invention

[0003] The purpose of this utility model is to address the problem that the current design of inverter test fixtures easily leads to messy wiring harnesses and poses safety hazards.

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0005] A multi-type inverter mounting test rack was developed to address the aforementioned issues.

[0006] The application is as follows:

[0007] A multi-type inverter mounting test rack includes a main test frame and an inverter mounting bracket. The upper end of the inverter mounting bracket is provided with a hook, and the center of the inverter mounting bracket is provided with a threaded hole and a mounting slot. Both ends of the main test frame are provided with a power circuit breaker and a grounding terminal. The inner end of the inverter mounting bracket is provided with an embedded groove, and the inner end of the embedded groove is provided with a positioning plate. The center of the positioning plate is provided with a positioning rod and a positioning hole. The upper end of the positioning plate is provided with a positioning shaft and a positioning ring. The outer end of the positioning ring is provided with a moving rod, and the outer end of the moving rod is provided with a moving frame. The inner end of the moving frame is provided with a rack, the outer end of the rack is provided with a gear, the lower end of the gear is provided with a worm gear, and the outer end of the worm gear is provided with a worm.

[0008] As a preferred technical solution of this application, the upper end of the inverter bracket is provided with a hook, the threaded hole and the mounting slot penetrate through the outer surfaces of the front and rear ends of the inverter bracket, and the right end of each inverter bracket is electrically connected to the power circuit breaker and the grounding terminal.

[0009] As a preferred technical solution of this application, the embedded groove is embedded in the upper inner surface of the inverter hanger and the hook, and the positioning plate moves along the embedded groove through the positioning rod and the positioning hole.

[0010] As a preferred technical solution of this application, the upper end of the positioning plate is fixedly connected to the positioning shaft, the outer end of the positioning shaft is movably connected to the positioning ring, and the outer end of the positioning ring is movably connected to the moving rod.

[0011] As a preferred technical solution of this application, the tail end of the moving rod is fixedly connected to the moving frame, the inner end of the moving frame is fixedly connected to the rack, the rack is meshed with the gear, and the gear is wrapped around the inner end of the moving frame.

[0012] As a preferred technical solution of this application, the lower end of the gear is fixedly connected to the worm gear, and the outer end of the worm gear is meshed with the worm through threads.

[0013] As a preferred technical solution of this application, the upper end of the gear is provided with a rotating groove and a rotating ring, the upper end of the rotating ring is provided with a spring, and the outer end of the moving rod is provided with a groove plate.

[0014] As a preferred technical solution of this application, the rotating groove is embedded in the upper inner surface of the gear, the inner end of the rotating groove is movably connected to the rotating ring, the upper end of the rotating ring is movably connected to the spring, and the moving rod moves up and down along the groove plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] By using inverter brackets, hooks, threaded holes, mounting slots, power circuit breakers, and grounding terminals, different types of inverters can be installed on the test main frame for testing. The inverter brackets are connected to the corresponding inverters through threaded holes and mounting slots, and can also be connected through worm gears. The rear side of the corresponding inverter bracket is connected to the test main frame wires, and the corresponding inverter bracket is connected to the power circuit breaker and grounding terminal for individual control, reducing the pulling of the wiring harness and facilitating testing.

[0018] By incorporating an embedded slot, positioning plate, positioning rod, positioning hole, positioning shaft, positioning ring, moving rod, moving frame, rack, gear, worm gear, worm, spring, rotating slot, rotating ring, and slot plate, the inverter installation mechanism allows the worm to drive the worm wheel to rotate during installation. The worm wheel's rotation drives the upper gear to rotate, which in turn drives the rack to move. This movement, in turn, drives the moving rod connected to the moving frame to push the positioning plate, connected to the linkage ring and linkage shaft, to rotate along the limits defined by the positioning hole and positioning rod. This ensures stable installation of the inverter mount and inverter, while simultaneously hooking the lower end of the positioning plate into the test frame, thus stabilizing the inverter mount.

[0031] The upper end of the inverter bracket 2 is provided with a hook 3, and the threaded hole 4 and the mounting slot 5 penetrate through the outer surfaces of the front and rear ends of the inverter bracket 2. The right end of each inverter bracket 2 is electrically connected to the power circuit breaker 6 and the grounding terminal 7.

[0032] The embedded groove 8 is embedded in the upper inner surface of the inverter bracket 2 and the hook 3, and the positioning plate 9 moves along the embedded groove 8 through the positioning rod 10 and the positioning hole 11.

[0033] The positioning hole 11 extends through the outer surfaces of the front and rear ends of the positioning plate 9. The positioning hole 11 is movably connected to the positioning rod 10, and the positioning rod 10 is fixedly installed at the inner end of the embedded groove 8.

[0034] The upper end of the positioning plate 9 is fixedly connected to the positioning shaft 12, the outer end of the positioning shaft 12 is movably connected to the positioning ring 13, and the outer end of the positioning ring 13 is movably connected to the moving rod 14.

[0035] The positioning ring 13 is movably connected to the positioning shaft 12, and the moving rod 14 moves along the inner end of the positioning ring 13.

[0036] The tail end of the moving rod 14 is fixedly connected to the moving frame 15, the inner end of the moving frame 15 is fixedly connected to the rack 16, the rack 16 is meshed with the gear 17, and the gear 17 is wrapped around the inner end of the moving frame 15.

[0037] By limiting the movable frame 15 and the rack 16, the movable rod 14 can be moved when the gear 17 rotates.

[0038] The lower end of the gear 17 is fixedly connected to the worm gear 18, and the outer end of the worm gear 18 is engaged with the worm 19 by threads.

[0039] The rotation of the linkage gear 17 can be ensured by the linkage between the worm gear 18 and the worm 19.

[0045] Furthermore, during inverter installation, the worm gear 19 drives the worm wheel 18 to rotate, which in turn drives the upper gear 17 to rotate. The rotation of the gear 17 drives the rack to move, which in turn drives the moving rod 14 connected to the moving frame 15 to push the positioning plate 9 connected to the linkage ring and the linkage shaft to rotate along the positioning hole 11 and the positioning rod 10. During inverter installation, this facilitates the stable installation of the inverter bracket 2 and the inverter, while also allowing the lower end of the positioning plate 9 to hook into the test main frame 1, thus stabilizing the inverter bracket 2.
