[0025] With the rapid development of the new energy industry, especially the photovoltaic industry, the inverter is an important part of the photovoltaic energy storage system, and the inverter product also develops rapidly. Among them, the inverter is usually provided with multiple ports, and the ports are exposed on the side of the inverter. The inverter is connected with other devices through the ports.

[0026] However, the inverter often needs to be installed in an outdoor environment, and the exposed ports of the inverter may be touched by mistake, affecting the working stability of the inverter. Moreover, when the inverter is working, the external cable connected with the inverter is live, and is exposed in the environment, which has a safety hazard.

[0027] Therefore, the present application provides a protection device and a photovoltaic inverter device, which can protect the inverter and improve the working stability and safety of the inverter.

[0028] The embodiments of the present application first provide a protection device.

[0029] Figure 1 The structure schematic diagram of the protection device provided by the present application is provided. Figure 2 The exploded schematic diagram of the photovoltaic inverter device provided by the present application is provided.

[0030] As Figure 1 and Figure 2As shown, the protection device 100 can be applied to a photovoltaic inverter device 1000, which comprises the protection device 100 and an inverter 200. The inverter 200 has a terminal end 201, and the terminal end 201 is provided with a plurality of ports. The protection device 100 can be installed on the inverter 200 and shield the ports of the inverter 200. The cables of other devices outside the photovoltaic inverter device 1000 can pass through the protection device 100 and be connected to the ports, so as to achieve the effect of protecting the inverter 200.

[0031] Figure 3 An exploded view of the protection device provided in the present application is shown.

[0032] As shown in Figure 2 and Figure 3 In the present embodiment, the protection device 100 comprises a protection frame 10, a shielding plate 20 and a detachable assembly 30. The interior of the protection frame 10 forms an accommodation space 11. The protection frame 10 is provided with a mounting port 12, a wiring port 13 and a threading hole 14, which are all communicated with the accommodation space 11.

[0033] The accommodation space 11 is the internal space of the protection frame 10. The accommodation space 11 can accommodate the terminal end 201 and the ports of the inverter 200, and can also accommodate the part of the cables of other devices outside the inverter 200.

[0034] The mounting port 12 is arranged corresponding to the terminal end 201 of the inverter 200. The size of the mounting port 12 is adapted to the size of the terminal end 201 of the inverter 200. The terminal end 201 of the inverter 200 can pass through the mounting port 12 to enter the accommodation space 11, so that the ports of the inverter 200 are accommodated in the accommodation space 11.

[0035] The threading hole 14 is arranged corresponding to the cables of other devices outside. The diameter of the threading hole 14 is greater than the diameter of the cables, so that the threading hole 14 can be passed through by the cables. The cables outside the protection frame 10 can pass through the threading hole 14 to enter the accommodation space 11 and be connected to the ports in the accommodation space 11.

[0036] The wiring port 13 is arranged on one side of the inverter 200. The wiring port 13 can expose the accommodation space 11 to the protection frame 10.

[0037] The shielding plate 20 is arranged corresponding to the wiring port 13. The detachable assembly 30 is arranged between the protection frame 10 and the shielding plate 20. The shielding plate 20 is detachably connected to the protection frame 10 through the detachable assembly 30.

[0038] When the shielding plate 20 is fixed to the protection frame 10, the shielding plate 20 shields the wiring port 13, and at this time, the shielding plate 20 cooperates with the protection frame 10 to shield the wiring terminal 201 of the inverter 200. When the shielding plate 20 is detached from the protection frame 10, the wiring port 13 exposes the accommodation space 11 to the protection frame 10, so that the worker can perform wiring or detaching operation on the port in the accommodation space 11.

[0039] It can be understood that by inserting the wiring terminal 201 of the inverter 200 into the accommodation space 11 from the mounting port 12, the protection frame 10 and the shielding plate 20 can be used to shield the wiring terminal 201 of the inverter 200, thereby isolating the outside, avoiding the exposure of the port of the inverter 200 to cause misoperation, and improving the working stability and safety of the inverter 200. At the same time, the cable outside the protection frame 10 can enter the accommodation space 11 to connect the port of the inverter 200 through the threading hole 14, so as to ensure that the inverter 200 can be normally wired with other devices outside.

[0040] Figure 4 The structure diagram of the protection frame provided in the present application is shown.

[0041] As shown in Figure 3 and Figure 4 , in some embodiments, the protection frame 10 includes a bottom plate 40, a surrounding plate 50 and two side plates 60. Among them, the surrounding plate 50 is arranged on one side of the bottom plate 40, and the two side plates 60 are arranged at both ends of the bottom plate 40, the bottom plate 40, the surrounding plate 50 and the two side plates 60 form the accommodation space 11, the bottom plate 40 and the two side plates 60 form the wiring port 13, the shielding plate 20 is arranged opposite to the surrounding plate 50, and the surrounding plate 50 and the two side plates 60 form the mounting port 12.

[0042] As shown in Figure 2 and Figure 4 , for example, the wiring terminal 201 of the inverter 200 is located at the lower end of the inverter 200. The lower end of the inverter 200 is rectangular as a whole, and the distance between the two side plates 60 is matched with the length of the wiring terminal 201 of the inverter 200, so that the wiring terminal 201 of the inverter 200 can be inserted into the mounting port 12.

[0043] It can be understood that the size of the mounting port 12 of the protection frame 10 can be configured according to actual needs such as the structure of the inverter 200, and the size of the accommodation space 11 of the protection frame 10 can be configured according to actual needs such as the number of ports of the inverter 200, which is not limited in the present application.

[0044] Exemplarily, the two side plates 60 are parallel to each other, and the bottom plate 40, the side plates 60 and the enclosing plate 50 are perpendicular to each other. The bottom plate 40, the side plates 60 and the enclosing plate 50 can be formed by bending a whole plate. It can be understood that the protective frame 10 is integrally formed, which simplifies the structural design of the protective frame 10 and improves the production efficiency of the protective frame 10.

[0045] In some embodiments, the side plate 60 extends in a direction away from the bottom plate 40 to form a mounting portion 61, and the mounting portion 61 is used to cooperate with the inverter 200 to be fixed. The side plate 60 is fixed to the side of the inverter 200 through the mounting portion 61, so that the protective frame 10 is fixed to the inverter 200. Exemplarily, the two side plates 60 both have the mounting portion 61, and the two side plates 60 are respectively fixed to the two sides of the inverter 200 through the two mounting portions 61, so as to improve the connection stability between the protective frame 10 and the inverter 200.

[0046] In some embodiments, the mounting portion 61 is provided with a mounting hole 62, and the mounting hole 62 is used for a screw structure to pass through. The side of the inverter 200 is provided with a threaded hole 202. The screw structure can pass through the mounting hole 62 and be threadedly connected to the threaded hole 202, so that the mounting portion 61 is bolted and fixed to the side of the inverter 200.

[0047] It can be understood that the mounting portion 61 and the inverter 200 are detachably connected through the screw structure, which facilitates the installation or disassembly of the protective frame 10 and the inverter 200 by the staff.

[0048] Specifically, when it is needed to install the protective frame 10 on the inverter 200, the wiring end 201 of the inverter 200 can be inserted between the two mounting portions 61, the mounting hole 62 is aligned with the threaded hole 202, and then the screw structure is threadedly connected to the side of the inverter 200 through the mounting portion 61. When it is needed to disassemble the protective frame 10 from the inverter 200, the screw structure can be screwed out of the mounting portion 61, so that the protective frame 10 and the inverter 200 can be separated.

[0049] It is worth noting that, in the example of the present embodiment, the mounting portion 61 and the inverter 200 are fixed by bolting, and in other examples, the mounting portion 61 and the inverter 200 can also be fixed by clamping, interference fit, locking connection and the like, which are not limited in the present application.

[0050] In some embodiments, the mounting hole 62 has a plurality of mounting holes 62, and the plurality of mounting holes 62 includes a first mounting hole 621 and a second mounting hole 622, and the internal space of the first mounting hole 621 is larger than that of the second mounting hole 622. Exemplarily, the first mounting hole 621 is circular, and the second mounting hole 622 is waist-shaped.

[0051] When the protective frame 10 needs to be installed on the inverter 200, the second mounting hole 622 can provide a certain space for screw hole alignment, reducing the problem of multiple mounting holes 62 being difficult to align with multiple screw holes at the same time due to tolerance, making it easier for workers to install and fix.

[0052] In some embodiments, there are multiple threading holes 14, and the multiple threading holes 14 are respectively provided in one or more of the bottom plate 40, the surrounding plate 50, and the side plates 60. For example, the bottom plate 40 is provided with multiple threading holes 14, and the multiple threading holes 14 are spaced apart along the length direction of the bottom plate 40. One of the side plates 60 is provided with a threading hole 14, and the threading hole 14 is located at the upper end of the side plate 60.

[0053] By setting wire holes 14 on the bottom plate 40, the enclosure 50 or the side plate 60, cables can be passed through the bottom plate 40, the enclosure 50 or the side plate 60 to meet the wiring requirements of other external devices from different directions, thereby improving the applicability of the protective frame 10 in different application scenarios.

[0054] It can be understood that in the example of this embodiment, the bottom plate 40 and the side plate 60 are both provided with wire threading holes 14. In other examples, the enclosure 50 may also be provided with wire threading holes 14, and the bottom plate 40 or the side plate 60 may not be provided with wire threading holes 14. As long as the conditions for cable threading can be met, the specific configuration can be based on actual application requirements, and this application does not impose any restrictions on this.

[0055] In some embodiments, the protective frame 10 is further provided with a plurality of knockout portions 15. When the product leaves the factory, a stopper is formed inside the knockout portion 15, and when the staff needs it, the stopper inside the knockout portion 15 can be knocked off to form a gap in the knockout portion 15.

[0056] In this way, when a through hole needs to be added on the protection frame 10 for cables to pass through, the staff can knock down the knockout portion 15 to allow the corresponding cables of the inverter 200 to pass through.

[0057] In some embodiments, there are multiple knockout portions 15, and the multiple knockout portions 15 are respectively provided on one or more of the bottom plate 40, the enclosure 50, and the side plate 60. For example, the enclosure 50 is provided with multiple knockout portions 15, and the multiple knockout portions 15 are spaced apart along the length direction of the enclosure 50. The side plate 60 is provided with a knockout portion 15, and the knockout portion 15 is located at the lower end of the side plate 60.

[0058] By setting a knockout portion 15 on the bottom plate 40, the enclosure 50 or the side plate 60, cables can be passed through the bottom plate 40, the enclosure 50 or the side plate 60 to meet the wiring requirements of other external devices from different directions, thereby improving the applicability of the protective frame 10 in different application scenarios.

[0059] It can be understood that in the examples of the present embodiment, the surrounding plate 50 and the side plate 60 are both provided with the knock hole part 15, and in other examples, the bottom plate 40 can also be provided with the knock hole part 15, or the surrounding plate 50 or the side plate 60 can also not be provided with the knock hole part 15, as long as the condition of cable threading can be met, and the specific configuration can be based on the actual application requirements, which is not limited in the present application.

[0062] For example, the shielding plate 20 is provided with the lock hook 31 at both ends, and the hook-shaped end 311 of the lock hook 31 is arranged towards the protection frame 10. The protection frame 10 is provided with the carabiner 32 at both sides, and the carabiner 32 is rotatably arranged on the corresponding side plate 60.

[0063] When the shielding plate 20 needs to be installed, the shielding plate 20 can be covered on the wiring port 13, the hook-shaped ends 311 of the two lock hooks 31 are aligned with the two carabiners 32, and then the carabiners 32 are rotated and buckled on the hook-shaped ends 311 of the corresponding lock hooks 31, so that the two lock hooks 31 are fixed on both sides of the protection frame 10, and the installation of the shielding plate 20 is completed. When the shielding plate 20 needs to be dismounted, the carabiners 32 are rotated to be separated from the hook-shaped ends 311 of the corresponding lock hooks 31, so that the two carabiners 32 are separated from the hook-shaped ends 311 of the two lock hooks 31, and the dismounting of the shielding plate 20 is completed.

[0064] In some embodiments, the dismounting assembly 30 further includes a lock ring 33, the lock ring 33 is arranged on the protection frame 10, and the carabiner 32 is provided with a lock hole 321 for the lock ring 33 to pass through.

[0065] It can be understood that when the carabiner 32 fixes the lock hook 31, the lock ring 33 passes through the carabiner 32 through the lock hole 321, and the staff can set a padlock in the lock ring 33 to prevent the carabiner 32 from rotating, thereby achieving the anti-theft function.

[0066] It is worth noting that in the present embodiment, the carabiner structure is used as the dismounting assembly 30, and in other embodiments, the dismounting assembly 30 can also use a screw structure as the dismounting assembly 30, as long as the detachable connection effect can be achieved, which is not limited in the present application.

[0067] The present embodiment also provides a photovoltaic inverter device.

[0068] As shown in Figure 2 and Figure 3 The photovoltaic inverter device 1000 comprises a protection device 100 and an inverter 200, the protection device 100 covers one end of the inverter 200 with a port. Specifically, the wiring end 201 of the inverter 200 enters the accommodation space 11 through the mounting port 12, so that the port of the inverter 200 is accommodated in the protection device 100. The cable of other equipment outside the photovoltaic inverter device 1000 can pass through the cable hole 14 of the protection device 100 and be connected to the inverter 200.

[0069] In actual application, the protection device 100 can shield and protect the cable connected to the inverter 200, so as to improve the working stability and safety of the inverter 200. Moreover, the protection device 100 provided by the embodiment of the present application is designed ingeniously, has simple structure, is convenient to install or disassemble, and has strong practical operability.
