Description

Technical Field

[0001] This utility model relates to the field of energy storage converter technology, and more specifically, to a string energy storage converter device. Background Technology

[0002] Energy storage converters in energy storage systems are key devices used for bidirectional energy conversion between energy storage devices and the power grid or load. Energy storage converters can convert direct current (DC) to alternating current (AC) and vice versa, to adapt to different power supply and load requirements. Based on their architecture and application, energy storage converters can be divided into centralized energy storage converters and string energy storage converters. String energy storage converters are a technical architecture that connects multiple miniaturized, modular energy storage converter units in series or parallel to collaboratively achieve energy conversion and control within the energy storage system.

[0003] A search revealed Chinese patent application number 202320428657.2, which discloses a string energy storage converter device. The device includes a support frame, several energy storage converters, and a combiner box. The support frame has a placement space, which is divided into an upper and lower placement section by a partition. Several energy storage converters are arranged side-by-side in the upper placement section, with a DC cable connected to one side of each converter and an AC cable connected to the other side. The combiner box is located in the lower placement section. The partition has several through holes near both the DC and AC cables, through which the DC and AC cables pass and connect to the combiner box. By arranging the energy storage converters side-by-side and providing DC and AC cables on both sides of each converter, with the cables passing through the through holes and directly connecting to the combiner box in the lower placement section, the wiring of the string energy storage converter device can be reduced. However, the aforementioned patents have the following drawbacks: the protective netting is prone to clogging during long-term operation, requiring frequent disassembly and cleaning, which not only increases maintenance costs but also the workload of staff. Therefore, this utility model proposes a new solution. Utility Model Content

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0015] like Figures 1-6 As shown, this embodiment proposes a string energy storage converter device, including a support frame 21. The support frame 21 has an upper placement section and a lower placement section inside. Multiple energy storage converters 13 are placed in the upper placement section, and a combiner box 1 is placed in the lower placement section. Several fans are installed on the side of each energy storage converter 13 near the combiner box 1. A ventilation space is provided below the fans. A protective net 4 installed on the outer wall of the support frame 21 surrounds the ventilation space. A protective plate is installed above the protective net 4 on the outer wall of the support frame 21. The protective plate protects the multiple energy storage converters 13 from all sides and also seals the support frame 21, allowing outside air to enter the ventilation space only through the protective net 4. Multiple ventilation holes 14 that cooperate with the fans are opened on the top of each energy storage converter 13. The device also includes: The partition 2 is fixedly installed between the upper and lower placement parts. The top of the partition 2 is equipped with a mounting bracket 16 for fixing the energy storage converter 13. Electric telescopic rods 19 are fixedly installed through the four corners of the partition 2. The moving end of the electric telescopic rod 19 is equipped with a mounting block 18 located inside the support frame 21. When in use, the electric telescopic rod 19 can drive the jet mechanism 12 to move through the mounting block 18, so that the jet mechanism 12 moves back and forth from top to bottom along the inner side of the protective net 4, so that the jet mechanism 12 can cover the entire range of the protective net 4, ensuring that the protective net 4 can be thoroughly cleaned and avoiding the problem of local cleaning dead corners. The jetting mechanism 12 is detachably installed between four mounting blocks 18 and located between the fixed frame 16 and the inner side of the protective net 4. The air collecting mechanism is detachably installed on the top of the support frame 21 and is used to collect the air discharged through the ventilation hole 14. The air collecting mechanism and the jetting mechanism 12 are connected by an air supply mechanism. During use, the jetting mechanism 12 can be used to clean the protective net 4 from the inside without manual disassembly and cleaning, which greatly reduces the workload in the maintenance process, reduces the labor burden of the staff, and reduces the damage to the protective net 4 caused by frequent disassembly. Moreover, during the jetting cleaning process, the air collecting mechanism can supply the air discharged by the energy storage converter 13 through its top ventilation hole 14 to the jetting mechanism 12 through the air supply mechanism, without the need for additional equipment such as fans to provide an air source for the jetting mechanism 12. The protective net 4 is cleaned without increasing the power consumption. The dust collection mechanism 5 is arranged around the outside of the discharge mechanism 6. The outer wall of the mounting block 18 is fixedly installed with a slider 20 for connecting the dust collection mechanism 5. The support frame 21 and the discharge mechanism 6 are both provided with sliding grooves 22 that cooperate with the slider 20. The exhaust end of the dust collection mechanism 5 is equipped with the discharge mechanism 6 that communicates with its interior. During the air jet cleaning process of the air jet mechanism 12, the dust collection mechanism 5 will move with the air jet mechanism 12 through the slider 20 installed on the mounting block 18, thereby synchronously collecting the dust blown by the air jet mechanism 12. The collected dust will be discharged to the outside through the discharge mechanism 6 to prevent the dust from being sucked in by the fan again and to prevent the blown dust from flying around everywhere.

[0016] like Figures 1-3As shown, in a preferred embodiment, based on the above method, the gas collection mechanism further includes a pad 7 fixedly installed on the top of the support frame 21. A gas collection hood 3 is detachably installed on the top of the pad 7. Multiple evenly distributed exhaust pipes 8 are installed through the top of the gas collection hood 3. Multiple through slots 15 are opened on the pad 7 to cooperate with the ventilation holes 14 on the top of the energy storage converter 13. A sealing gasket is provided on the contact surface between the pad 7 and the energy storage converter 13. The gas supply mechanism includes a first gas supply pipe 10 penetrating the pad 7. A hose 11 is installed at the bottom end of the first gas supply pipe 10. A first electric valve 9 is installed in the middle of the first gas supply pipe 10. A second electric valve 17 is installed in the middle of the exhaust pipe 8. It should be noted that during use, the sealing gasket can ensure the sealing between the gasket 7 and the energy storage converter 13, so that all the air discharged through the ventilation hole 14 can enter the interior of the gas collection hood 3. During normal operation, the air collected inside the gas collection hood 3 will be discharged through multiple exhaust pipes 8. When it is necessary to clean the protective net 4, the second electric valve 17 on the exhaust pipe 8 is closed and the first electric valve 9 on the first air supply pipe 10 is opened, so that the air collected inside the gas collection hood 3 is delivered to the jet mechanism through the first air supply pipe 10 and the hose 11.

[0017] like Figure 2 , Figure 3 and Figure 6 As shown, in a preferred embodiment, based on the above method, the jet mechanism 12 further includes a rectangular distribution pipe 121. Multiple evenly distributed jet pipes 123 are installed on the side wall of the distribution pipe 121 facing the protective net 4. A connector 122 for connecting the hose 11 is installed at the top of the distribution pipe 121. It should be noted that during use, the hose 11 delivers air to the distribution pipe 121 through the connector 122, and then blows it onto the protective net 4 through the multiple jet pipes 123, thereby cleaning it.

[0018] like Figures 1-4 As shown, in a preferred embodiment, based on the above method, the dust collection mechanism 5 further includes four rectangularly distributed dust collection hoods 501. Each dust collection hood 501 has an opening 504 on its sidewall facing the protective net 4. A guide hopper 502 communicating with the interior of each dust collection hood 501 is installed at its bottom. The dust collection hood 501 is detachably mounted on the slider 20 via connecting blocks 503 and bolts at both ends. It should be noted that during use, the dust cleaned by the jetting mechanism 12 enters the interior of the dust collection hood 501 through the opening 504, and is then conveyed to the discharge mechanism 6 via the guide hopper 502.

[0019] like Figures 1-4As shown, in a preferred embodiment, based on the above method, the discharge mechanism 6 further includes a dust discharge pipe 601 installed on the outer wall of the partition 2. The dust discharge pipe 601 is provided with multiple flexible connecting pipes 602 communicating with its interior. The end of each connecting pipe 602 away from the dust discharge pipe 601 is inserted into the interior of the guide hopper 502. It should be noted that during use, the multiple connecting pipes 602 transport the air and dust collected by the dust collection mechanism 5 into the interior of the dust discharge pipe 601, and then discharge it to the outside through the dust discharge pipe 601.

[0020] Specifically, the working principle of this series energy storage converter device is as follows: When it is necessary to clean the protective net 4, the second electric valve 17 on the exhaust pipe 8 is closed, and the first electric valve 9 on the first air supply pipe 10 is opened, so that the air collected in the air collection hood 3 is delivered to the jetting mechanism through the first air supply pipe 10 and the hose 11. During the cleaning process, the electric telescopic rod 19 can drive the jetting mechanism 12 to move through the mounting block 18, so that the jetting mechanism 12 moves back and forth along the inner side of the protective net 4 from top to bottom, so that the jetting mechanism 12 can cover the entire range of the protective net 4, ensuring that the protective net 4 can be thoroughly cleaned. During the jetting cleaning process, the dust collection mechanism 5 will move with the jetting mechanism 12 through the slider 20 installed on the mounting block 18, thereby synchronously collecting the dust blown by the jetting mechanism 12. The collected dust will be discharged to the outside through the discharge mechanism 6.
