Description

Technical Field

[0001] The utility model relates to a converter, in particular to an energy storage converter for distributed photovoltaic power generation, belonging to the technical field of converters. Background Technique

[0002] Distributed photovoltaic power generation specifically refers to photovoltaic power generation facilities built near user sites, with the operation mode of self-use by users on the user side, excess electricity上网, and characterized by balance regulation in the distribution system. In a distributed power generation system, energy storage is required through a storage battery, and the charged storage battery can supply power to a load. Before the storage battery supplies power to an AC load, a converter is used to convert direct current into alternating current.

[0003] However, when a traditional converter is in use, through holes are opened on the side wall for heat dissipation. Although this can make the air inside the converter circulate with the outside air, at the same time, external dust is easily introduced into the inside of the converter, which is not convenient for cleaning the inside of the converter. Content of the Utility Model

[0004] The purpose of the utility model is to provide an energy storage converter for distributed photovoltaic power generation to solve the above problems. While ensuring the air circulation inside and outside the converter, it can prevent dust from entering the inside of the converter, thus effectively ensuring the cleanliness inside the converter.

[0005] The utility model realizes the above purpose through the following technical solutions. An energy storage converter for distributed photovoltaic power generation includes a converter body, and a dust-proof structure is provided on the converter body. The dust-proof structure includes an outer frame, the outer frame is clamped on the converter body, two filter nets are fixedly connected to the outer frame, a connecting plate is fixedly connected to the converter body, a screw is threadedly connected to the connecting plate, and the end of the screw abuts against the outer frame.

[0006] Preferably, a rotating rod is fixedly connected to one end of the screw, and a pulling plate is fixedly connected to the outer frame.

[0007] Preferably, the outer frame is in a "day" - shaped structure, and the end of the cross - section of the connecting plate is in an L - shaped structure.

[0008] [[ID=归 28]]Preferably, a base is fixedly connected to the bottom end of the converter body, and a plurality of mounting holes are provided on the base.

[0009] Preferably, a touch screen is provided on the converter body, a connecting frame is fixedly connected to the converter body, and a baffle is slidably connected to the connecting frame.

[0010] Preferably, the cross - section of the connecting frame is in a "square" - shaped structure, and the end of the cross - section of the baffle is in an L - shaped structure.

[0011] Preferably, the connection frame is provided with a locking structure, the locking structure includes a locking block, the connection frame is slidably connected with the locking block, the baffle is provided with two slots, and one end of the locking block is engaged with one of the slots.

[0012] Preferably, a reset spring is sleeved on the outside of the clamping block, one end of the reset spring is fixedly connected to the clamping block, and the other end of the reset spring is fixedly connected to the connecting frame.

[0013] Preferably, the cross section of the block is T-shaped, and one end of the cross section of the block is trapezoidal.

[0014] The beneficial effect of the present invention is that during use, since a filter is provided on one side of the converter body, dust in the external air can be prevented from entering the interior of the converter body during the circulation between the internal air of the converter body and the external air, thereby effectively ensuring the cleanliness of the interior of the converter body, and when the filter needs to be disassembled and cleaned, it can be done by rotating the screw. Since the screw and the connecting plate are threadedly connected, as the screw rotates, one end of the screw will be moved away from the outer frame, and when there is no conflict between the screw and the outer frame, the outer frame can be pulled out from one side of the converter body. After the outer frame is pulled out, it will be more convenient to clean the filter, and regular cleaning of the filter can avoid clogging of the filter mesh, thereby effectively ensuring the filtration efficiency.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 As shown, a distributed photovoltaic energy storage converter includes a converter body 1, the converter body 1 is provided with a dustproof structure 2, the dustproof structure 2 includes an outer frame 201, the converter body 1 is engaged with the outer frame 201, the outer frame 201 is fixedly connected to two filters 202, the converter body 1 is fixedly connected to a connecting plate 206, the connecting plate 206 is threadedly connected to a screw 205, and the end of the screw 205 is in conflict with the outer frame 201.

[0022] As a technical optimization solution of the present invention, the outer frame 201 has a "sun"-shaped structure, the end of the cross-section of the connecting plate 206 has an L-shaped structure, one end of the screw 205 is fixedly connected to the rotating rod 204, and the outer frame 201 is fixedly connected to the pull plate 203, so that the outer frame 201 can be conveniently pulled by the pull plate 203.

[0023] As a technical optimization solution of the present invention, the bottom end of the converter body 1 is fixedly connected to a base 7, and a plurality of mounting holes 8 are provided on the base 7, so that the base 7 can be installed through the plurality of mounting holes 8 in conjunction with bolts.

[0024] As a technical optimization solution of the present invention, a touch screen 6 is provided on the converter body 1, a connecting frame 3 is fixedly connected to the converter body 1, a baffle 4 is slidably connected to the connecting frame 3, the cross-section of the connecting frame 3 is a "mouth"-shaped structure, and one end of the cross-section of the baffle 4 is an L-shaped structure, so the touch screen 6 can be shielded and protected by the baffle 4.

[0025] As a technical optimization solution of the present invention, a locking structure 5 is provided on the connecting frame 3, and the locking structure 5 includes a locking block 501. The connecting frame 3 is slidably connected with the locking block 501, and the baffle 4 is provided with two locking grooves 503. One end of the locking block 501 is engaged with one of the locking grooves 503. A reset spring 502 is provided on the outside of the locking block 501, and one end of the reset spring 502 is fixedly connected to the locking block 501, and the other end of the reset spring 502 is fixedly connected to the connecting frame 3. The cross-section of the locking block 501 is a T-shaped structure, and one end of the cross-section of the locking block 501 is a trapezoidal structure, so that sliding between the baffle 4 and the connecting frame 3 can be avoided.

[0026] When the utility model is in use, the base 7 can be installed and fixed by means of multiple mounting holes 8 and bolts. During use, since a filter screen 202 is provided on one side of the converter body 1, dust in the external air can be prevented from entering the converter body 1 during the circulation of air inside the converter body 1 and the external air, thereby effectively ensuring the cleanliness of the converter body 1. When the filter screen 202 needs to be disassembled and cleaned, the screw 205 can be rotated by the rotating rod 204.

At this time, the baffle 4 cannot slide on the connecting frame 3. Since the baffle 4 blocks the touch screen 6 at this time, the touch screen 6 can be prevented from being damaged by impact, thereby effectively improving the safety of use.
