Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] A photovoltaic energy storage inverter that supports battery-free operation includes an inverter body 1, an interface 3, and a protective mechanism 2 for protecting the interface 3. The interface 3 is located below the back side wall of the inverter body 1, and the protective mechanism 2 is located on the outside of the interface 3.

[0027] The protective mechanism 2 includes a fixed cover 4 and a fixed protective cover 8, a protective component for protecting the interface 3 and a reinforcing component for reinforcing the wiring. The fixed cover 4 is fixedly installed on the back side wall of the inverter body 1 and located outside the interface 3. The fixed protective cover 8 is fixedly installed on the side wall of the fixed cover 4.

[0028] The protective component is located above the fixed protective cover 8, and the reinforcement component is located outside the protective component.

[0029] The protective assembly includes a movable bracket 5, a movable protective cover 9, and a spring 10. The movable bracket 5 is fixedly installed on the side wall of the fixed cover 4. The spring 10 is located on the top of the movable protective cover 9, and the top of the spring 10 is fixedly installed on the inner top surface of the movable bracket 5. The bottom of the movable protective cover 9 abuts against the top of the fixed protective cover 8 under the elastic compression of the spring 10.

[0030] A spring 10 is installed on the top of the movable protective cover 9, and the top of the spring 10 is fixedly installed on the inner top surface of the movable bracket 5. This allows the installer to lift the movable protective cover 9 upward by holding the handle 11, insert the plug into the interior of the interface 3, and then release the handle 11. Under the elastic force of the spring 10, the bottom of the movable protective cover 9 and the top of the fixed protective cover 8 are pressed against each other, thereby protecting the interface 3 and preventing external rainwater from entering the interior of the interface 3 and affecting the normal use of the inverter body 1.

[0031] The movable protective cover 9 has sliding strips 7 on both sides of its sidewalls, and sliding grooves 6 are opened on both sides of the inner wall of the movable bracket 5. The ends of the sliding strips 7 are slidably connected to the inner wall of the sliding grooves 6. A handle 11 is also provided in the middle of the sidewall of the movable protective cover 9.

[0032] Meanwhile, slide bars 7 are provided on both sides of the movable protective cover 9, and slide grooves 6 are provided on both sides of the inner wall of the movable bracket 5. The ends of the slide bars 7 are slidably connected to the inner wall of the slide grooves 6, so that the direction of the movable protective cover 9 when sliding up and down is determined by the slide bars 7 sliding along the inner wall of the slide grooves 6, thereby increasing the stability of the movable protective cover 9 when moving up and down.

[0033] The sidewalls of the fixed protective cover 8 and the movable protective cover 9 that come into contact with each other are provided with notches 12 at positions corresponding to the interface 3, so that wiring can pass through the notches 12 and connect to the interface 3.

[0034] The reinforcement components include reinforcement brackets 13 and a pressing module. The reinforcement brackets 13 are symmetrically arranged on the side walls of the fixed protective cover 8 and are located below the recess 12. The pressing module is arranged on the top side wall of the movable bracket 5.

[0035] The pressing module includes a top plate 14, a telescopic rod 15, and a pressing frame 16. The top plate 14 is fixedly installed on the side wall at the top of the movable bracket 5. The telescopic rod 15 is fixedly installed on the bottom surface of the top plate 14. The working ends of the telescopic rod 15 are fixedly installed with the pressing frame 16. The bottom end of the pressing frame 16 is provided with a notch 18 corresponding to the wiring.

[0036] Meanwhile, a top plate 14 is provided on the side wall of the top of the movable bracket 5 above the wiring. The working end of the telescopic rod 15 provided on the bottom surface of the top plate 14 is fixedly installed on the lower pressure frame 16. The top of the lower pressure frame 16 and the top of the reinforcing bracket 13 fixedly installed on the side wall of the lower fixed protective cover 8 are pressed against each other. The bottom end of the lower pressure frame 16 is provided with a notch 18. The inside of the notch 18 is provided with a compression ball 19 for pressing and fixing the wiring. The wiring is pressed and fixed by the compression ball 19, which strengthens the wiring and prevents the wiring interface from loosening under the external wind, thus affecting the use of the inverter body 1.

[0037] Guide rods 17 are fixedly installed on the top surface of the lower pressure frame 16. The top ends of the guide rods 17 penetrate the top plate 14 and are slidably connected to the top plate 14. Guide rods 17 are also fixedly installed on the top surface of the lower pressure frame 16. The guide rods 17 penetrate the top plate 14 and are slidably connected to the top plate 14 so as to slide on the top of the top plate 14 through the guide rods 17, ensuring the stability of the lower pressure frame 16 when it is raised and lowered.

[0038] When using the inverter, the worker manually lifts the movable protective cover 9 by holding the handle 11, inserts the wiring plug into the interface 3 on the back of the inverter body 1, and then releases the handle 11. The movable protective cover 9 descends to the top of the fixed protective cover 8 under the elastic force of the spring 10. The interface 3 is further protected by the fixed protective cover 8 and the movable protective cover 9 to prevent external rainwater from entering the interior of the interface 3 and affecting the normal use of the inverter body 1. At the same time, after the wiring is completed, the lower pressure frame 16 is pushed down by activating the telescopic rod 15. This causes the compression ball 19 inside the notch 18 at the bottom of the lower pressure frame 16 to compress the wiring, reinforcing the wiring and improving its stability.

[0039] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
