Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic energy storage inverters, and particularly relates to an energy storage inverter device convenient for maintenance. Background Art

[0002] A photovoltaic energy storage inverter can convert the variable DC voltage generated by a photovoltaic solar panel into commercial power frequency alternating current, which can be fed back into the commercial power transmission system or used for an off-grid power grid. Moreover, it is equipped with energy storage batteries and can operate off-grid, switching to the battery power supply mode to supply power to loads. The photovoltaic energy storage inverter will generate a large amount of heat during long-term operation. If heat dissipation is not carried out in time, it will affect the normal use of the photovoltaic energy storage inverter. Currently, there are heat sinks for heat dissipation on existing photovoltaic energy storage inverters. However, the process of natural heat dissipation of the photovoltaic energy storage inverter through the heat sink is slow. Secondly, the heat sink is integrally arranged with the photovoltaic energy storage inverter, which is not convenient for disassembly and repair, and the heat sink cannot be applied to the heat dissipation of multiple photovoltaic energy storage inverters.

[0003] In addition, some existing common ventilation and heat dissipation methods will not only cause external dust to enter the interior of the photovoltaic energy storage inverter, but also external moisture is likely to enter the interior of the photovoltaic energy storage inverter, thus affecting the normal operation of the energy storage converter. Although some can dehumidify the moisture entering the interior of the photovoltaic energy storage inverter through drying components, however, the dehumidifying components in the long-term use state are prone to saturation, resulting in a simultaneous deterioration of air permeability and dehumidification performance. Therefore, an energy storage inverter device convenient for maintenance is proposed. Summary of the Invention

[0025] The dust removal mechanism 7 includes an annular frame 71 fixedly installed on one side of the side plate 11 away from the inverter component 2. A filter plate 72 is rotatably installed inside the annular frame 71. An annular filtering part 721 is formed on the filter plate 72. One side of the exhaust pipe one 31 and the intake pipe one 41 close to the filter plate 72 are both slidably connected to the annular filtering part 721.

The plurality of scraping strips 74 are all slidably connected to the side of the filter plate 72 away from the side plate 11.

[0026] In this embodiment: during use, start the motor 62 to drive the single-crankshaft two 49 and the single-crankshaft one 39 to rotate. When the single-crankshaft two 49 rotates and pulls the push rod two 47 through the rectangular frame two 48, the push rod two 47 pulls the piston plate two 45 away from the partition plate 42. At this time, the space between the piston plate two 45 and the partition plate 42 increases and the air pressure decreases. At this time, the external cold air will pass through the annular filter part 721 and then pass through a plurality of check valves three 43 and enter between the partition plate 42 and the piston plate two 45. Then, when the single-crankshaft two 49 rotates and pushes the push rod two 47 through the rectangular frame two 48, the push rod two 47 pushes the piston plate two 45 close to the partition plate 42. At this time, the space between the piston plate two 45 and the partition plate 42 decreases, which will cause the air between the piston plate two 45 and the partition plate 42 to pass through a plurality of check valves four 46 and enter the intake cylinder two 44 communicated with the inverter housing 1; Continuing from the above, during the process of the external cold air flowing through the check valve three 43 and the check valve four 46, the corresponding dehumidifying member 53 will adsorb and dehumidify this part of the cold air, so as to ensure that the cold air entering the inverter housing 1 is relatively dry; Continuing from the above, when the single-crankshaft two 49 rotates and pulls the push rod two 47 through the rectangular frame two 48, the rotating single-crankshaft one 39 will push the push rod one 37 through the rectangular frame one 38, and the push rod one 37 will push the piston plate one 35 away from the annular plate 33. As the space between the annular plate 33 and the piston plate one 35 increases, the hot air inside the inverter housing 1 will pass through a plurality of check valves one 34 and enter between the annular plate 33 and the piston plate one 35. When the single-crankshaft two 49 rotates and pushes the push rod two 47 through the rectangular frame two 48, the rotating single-crankshaft one 39 will pull the push rod one 37 through the rectangular frame one 38, and the push rod one 37 will pull the piston plate one 35 towards the annular plate 33. As the distance between the annular plate 33 and the piston plate one 35 decreases, the hot air between the annular plate 33 and the piston plate one 35 will pass through a plurality of check valves two 36 and move to the side of the piston plate one 35 away from the annular plate 33. Then, when the piston plate one 35 is away from the annular plate 33 again, the piston plate one 35 will push the hot air on this side towards the exhaust cylinder one 31. During this process, this part of the hot air will dry the dehumidifying member 53 located between the exhaust cylinder one 31 and the exhaust cylinder two 32; During the rotation of the single-crankshaft one - 39 and the single-crankshaft two - 49, the fixed shaft 638 will be driven to rotate. The rotation of the fixed shaft 638 will drive the half-gear 637 to rotate. After the rotating half-gear 637 meshes with the rack 636, the rack 636 will be pulled away from the limit plate 639. The limit plate 639 will then pull the cylinder 633 away from the round box 51 through the prism 635 and the connecting plate 634. With the cooperation of multiple spiral guide grooves 6331 and spiral guide ribs 6311, the moving cylinder 633 will drive the rotating shaft 631 to rotate. The rotating shaft 631 will then drive the rotating disk 52 to rotate through the one-way bearing 632. The rotating rotating disk 52 can adjust the positions of multiple dehumidifying parts 53, so that the dehumidifying parts 53 that have adsorbed the moisture in the cold air entering the inverter housing 1 can rotate and move towards the hot air discharged between the exhaust pipe one - 31 and the exhaust pipe two - 32 for drying. When the half-gear 637 is separated from the rack 636, the compressed spring 6310 will drive the connecting plate 634 to move away from the limit plate 639 for reset. At this time, the connecting plate 634 will drive the cylinder 633 to move towards the round box 51, and the one-way bearing 632 can only rotate in one direction. At this time, the rotating shaft 631 will rotate idly into the cylinder 633 and will not drive the rotating disk 52 to rotate through the one-way bearing 632; As described above, when the external cold air enters the intake pipe one - 41, the annular filtering part 721 can filter the dust in the cold air to ensure the cleanliness of the cold air entering the inverter housing 1. During the rotation of the rotating disk 52, the filter plate 72 can be driven to rotate through the round shaft 73. By adjusting the position of the annular filtering part 721 communicating with the intake pipe one - 41 in real time, the part of the annular filtering part 721 that filters dust can be rotated to the position communicating with the exhaust pipe one - 31. At this time, the hot air discharged from the round box 51 can blow back the annular filtering part 721, thereby completing the dredging of the annular filtering part 721. In addition, during the rotation of the filter plate 72, multiple scraping strips 74 can clean the surface of the annular filtering part 721, thereby preventing dust from adhering and accumulating on the annular filtering part 721 and ensuring that the annular filtering part 721 has better filtering performance.

[0027] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
