[0004] In the above solution, a door lock is used to fix the maintenance door to the main body of the three-phase energy storage converter. However, this solution still has the following drawbacks: the door lock is set on the surface of the maintenance door, and the lock hole is directly exposed to the external environment. There is a risk that the maintenance door may be pried open directly through the lock hole, which reduces the safety of the energy storage converter. Utility Model Content

[0005] The purpose of this invention is to provide a protective structure for an energy storage converter to address the problem that the keyhole is directly exposed to the external environment, which may lead to the risk of the maintenance door being pried open directly through the keyhole, thus reducing the safety of the energy storage converter.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a protective structure for an energy storage converter, including a protective shell, two protective cabinet doors rotatably disposed on one side of the protective shell, two storage slots opened on the left side of the right protective cabinet door, a motor fixed on one side of the right protective cabinet door, a rotating hole opened on one side of the interior of the storage slot, the output shaft of the motor being rotatably inserted into the rotating hole, a limiting plate being fixedly inserted into the surface of one end of the motor output shaft passing through the rotating hole, two limiting slots opened on the right side of the left protective cabinet door, the storage slots and the limiting slots being positioned correspondingly, and the limiting plate and the limiting slots being slidably disposed.

[0007] Preferably, a partition plate is fixed inside the protective shell, and the top surface of the partition plate has a plurality of wire openings.

[0008] Preferably, a plurality of sliding plates are slidably disposed above the partition plate, the bottom surface of the sliding plates is provided with a gathering groove, and a plurality of sliding columns are fixed on the top surface of the partition plate, the sliding plates and sliding columns being slidably inserted.

[0009] Preferably, a positioning plate is fixed to one side of the sliding plate, and a plurality of threaded grooves are provided on the top surface of the partition plate. A fixing bolt is rotatably inserted into the positioning plate, and one end of the fixing bolt passes through the positioning plate and is threadedly connected to the threaded groove.

[0010] Preferably, a number of ventilation openings are provided on one side of the protective cabinet door, a fixed frame is provided inside the ventilation opening, a positioning groove is provided on the surface of the fixed frame, the inner wall of the positioning groove is fixed to the inner wall of the ventilation opening, two dustproof nets are fixed inside the fixed frame, and a number of air vents are provided on both sides of the protective shell.

[0011] Preferably, a base plate is fixed to the bottom surface of the protective shell, an elastic pad is fixed to the bottom surface of the base plate, and a stabilizing plate is fixed to the bottom surface of the elastic pad.

[0012] Compared with existing technologies, the protection structure of an energy storage converter that adopts the above technical solution has the following beneficial effects:

[0013] 1. When the energy storage converter is in operation, it is inside the protective enclosure. At this time, the two protective cabinet doors are closed, and the storage slot and the limiting slot are connected together. Then, the output shaft of the motor drives the limiting plate into the limiting slot, which fixes the two protective cabinet doors together. The motor is fixed on the side of the protective cabinet door that is close to the internal space of the protective enclosure, and the limiting plate is inside the storage slot and the limiting slot. Therefore, there are no keyholes or other gaps on the surface of the protective cabinet door that can connect to the external environment, which can prevent the protective cabinet door from being pried open and increase the safety of the energy storage converter inside the protective enclosure.

[0014] 2. After the wires pass through the wire opening, the staff will bundle multiple wires together. Then, the staff will put the sliding plate on the wires, so that the bundled wires are confined inside the bundling groove. Then, the staff will put the fixing bolt through the positioning plate and apply rotational force to screw the fixing bolt into the threaded groove, and fix the sliding plate to the top surface of the partition plate. This increases the neatness of the wires inside the protective shell and facilitates maintenance and management.

[0015] Third, as the energy storage converter inside the protective enclosure operates, a large amount of heat will accumulate inside the protective enclosure. At this time, as air flows through the vents and air outlets in and out of the protective enclosure, the heat inside the protective enclosure can be dissipated, thus reducing the temperature of the internal environment of the protective enclosure.

Two limiting slots 20 are opened on the right side of the left protective cabinet door 10. The storage slots 16 and the limiting slots 20 are positioned correspondingly. The limiting plate 19 and the limiting slots 20 are slidably arranged. A partition plate 3 is fixed inside the protective housing 1. Several wire openings 4 are opened on the top surface of the partition plate 3.

[0024] During use, the energy storage converter is located inside the protective housing 1 in the working state. At this time, the two protective cabinet doors 10 are closed, and the storage slot 16 and the limiting slot 20 are connected together. Then, the output shaft of the motor 17 drives the limiting plate 19 into the limiting slot 20, which fixes the two protective cabinet doors 10 together. The motor 17 is fixed on the side of the protective cabinet door 10 near the internal space of the protective housing 1, and the limiting plate 19 is inside the storage slot 16 and the limiting slot 20. Therefore, there are no keyholes or other gaps on the surface of the protective cabinet door 10 that can connect to the external environment, which can prevent the protective cabinet door 10 from being pried open and increase the safety of the energy storage converter inside the protective housing 1.

[0025] like Figure 2 and Figure 4 As shown, several sliding plates 2 are slidably arranged above the partition plate 3. The bottom surface of the sliding plate 2 is provided with a gathering groove 5. Several sliding posts 6 are fixed on the top surface of the partition plate 3. The sliding plates 2 and the sliding posts 6 are slidably inserted. A positioning plate 7 is fixed on one side of the sliding plate 2. Several threaded grooves 8 are provided on the top surface of the partition plate 3. A fixing bolt 9 is rotatably inserted on the positioning plate 7. One end of the fixing bolt 9 passes through the positioning plate 7 and is threadedly connected to the threaded groove 8.

[0026] During use, after the wires pass through the wire opening 4, the staff will bundle multiple wires together. Then, the staff will fasten the sliding plate 2 onto the wires, so that the bundled wires are confined inside the bundling groove 5. Subsequently, the staff will pass the fixing bolt 9 through the positioning plate 7 and apply a rotational force to screw the fixing bolt 9 into the threaded groove 8, fixing the sliding plate 2 to the top surface of the partition plate 3. This increases the neatness of the wires inside the protective shell 1, making maintenance and management easier.

[0027] like Figure 2 As shown, a number of ventilation openings 11 are provided on one side of the protective cabinet door 10. A fixed frame 12 is provided inside the ventilation opening 11. A positioning groove 13 is provided on the surface of the fixed frame 12. The inner wall of the positioning groove 13 is fixed to the inner wall of the ventilation opening 11. Two dustproof nets 14 are fixed inside the fixed frame 12. A number of ventilation openings 15 are provided on both sides of the protective shell 1. A base plate 21 is fixed on the bottom surface of the protective shell 1. An elastic pad 22 is fixed on the bottom surface of the base plate 21. A stabilizing plate 23 is fixed on the bottom surface of the elastic pad 22.

[0028] During use, as the energy storage converter inside the protective housing 1 operates, a large amount of heat will accumulate inside the protective housing 1. At this time, as air flows through the vent 11 and the air vent 15 in the environment inside and outside the protective housing 1, the heat inside the protective housing 1 can be discharged, thereby reducing the temperature of the environment inside the protective housing 1.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
