Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, specifically a 5MWh energy storage system boost converter. Background Technology

[0002] The 5MWh energy storage system boost converter is an integrated device that integrates functional modules such as battery energy storage system (BESS), boost converter (PCS), transformer and control system into one unit. It is mainly used to realize the storage, boosting and grid connection of electrical energy.

[0003] A review of publication number CN219018282U reveals a prefabricated energy storage booster unit. This technology discloses "a prefabricated energy storage booster unit, comprising: a base; and a PCS cabinet, a transformer compartment, a medium-voltage switch compartment, and a communication cabinet mounted on the base; the transformer compartment includes a first prefabricated enclosure and a transformer installed within the first prefabricated enclosure; the medium-voltage switch compartment includes a second prefabricated enclosure and a switchgear installed within the second prefabricated enclosure; the PCS cabinet, the transformer, and the switchgear are connected sequentially, and the PCS cabinet is connected to the communication cabinet." This technology offers advantages such as "the PCS cabinet, transformer compartment, medium-voltage switch compartment, and communication cabinet are all mounted on the base, and moving the base allows for the overall movement of the PCS cabinet, transformer compartment, medium-voltage switch compartment, and communication cabinet. Furthermore, the external placement of the PCS cabinet, communication cabinet, and isolation transformer cabinet provides good heat dissipation."

[0004] In the aforementioned solution, the cooling system employs a fan combined with ventilation holes. While this achieves some cooling effect through air convection, this open internal ventilation structure has significant limitations. Due to the lack of an effective dust barrier, the equipment continuously draws in dust and suspended particles from the outside air during operation. Over time, these contaminants accumulate inside the equipment, gradually clogging the cooling ducts and filters, leading to a significant decrease in heat dissipation performance. Furthermore, they may intrude into precision components such as circuit boards and connectors, causing poor contact or deterioration of insulation performance. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a 5MWh energy storage system integrated booster unit that achieves intelligent ventilation through temperature-controlled linked blades: at high temperatures, the blades open synchronously, combining with S-shaped air ducts and dustproof nets for efficient heat dissipation and dust prevention; at normal temperatures / when the system is shut down, the blades close, forming multiple seals with rubber strips and upper and lower baffles to effectively prevent dust intrusion.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a 5MWh energy storage system boost converter, comprising a base, on which a main body mechanism is mounted for energy storage, boosting, and grid connection; the main body mechanism is equipped with a heat dissipation and dust prevention mechanism for heat dissipation and dust prevention, the heat dissipation and dust prevention mechanism comprising:

[0007] The ventilation assembly includes several outer frames mounted on a base, with a dustproof net fixed to the inner end of each outer frame;

[0008] The control component includes a frame fixed to the inner end of the outer frame, several blades rotatably mounted between the inner walls of both ends of the frame, a bracket fixed to one end of each blade, a connecting rod pivotally connected between the brackets, a motor mounted on the outer wall of the frame for driving one of the blades to rotate, a fan cover fixed on the frame, and a cooling fan installed inside the fan cover.

[0009] Preferably, the ventilation assembly further includes an inner frame fixed inside the outer frame, and a plurality of ventilation ducts are fixed inside the inner frame at equal intervals along the longitudinal direction.

[0010] Preferably, the control component further includes adhesive strips fixed to the upper and lower outer surfaces of the blade.

[0011] Preferably, the control component further includes an upper baffle fixed inside the upper part of the frame, and a lower baffle fixed inside the lower part of the frame.

[0012] Preferably, the control component further includes recesses formed at the upper and lower ends of the frame.

[0013] Preferably, the main structure includes a cabin fixed to the top of the base, a dry-type transformer installed at the right end inside the cabin, a high-voltage vacuum circuit breaker installed at the front left end inside the cabin, a high-voltage switch cabinet installed at the rear left end inside the cabin, and a converter installed at the right end of the top of the base.

[0014] Beneficial effects

[0015] This invention provides a 5MWh energy storage system integrated boost converter. Compared with the prior art, it has the following advantages:

[0016] 1. When the internal temperature of the cabin is high, one of the blades is driven to rotate through the output end of the motor. The blade drives the other supports to rotate through the bracket and connecting rod. The other supports drive the corresponding blades to rotate, thereby controlling each blade to open synchronously. This works in conjunction with the cooling fan and ventilation components to provide ventilation and heat dissipation. At the same time, the ventilation path is extended through several ventilation ducts and guided into an S-shape. Dust screens are also used to reduce the entry of external dust.

[0017] 2. When the internal temperature of the cabin is normal or not in operation, several blades close simultaneously. Adjacent blades can be bonded together with rubber strips to improve the sealing between adjacent blades after closure. In addition, the rubber strips prevent direct collision and contact between the blades when they close. At the same time, the uppermost and lowermost blades can be bonded to the upper baffle and lower baffle respectively to form a complete sealing surface, improving the sealing between the blades and the frame after closure, thereby preventing external dust from entering.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 6This utility model provides a technical solution: a 5MWh energy storage system boost converter, including a base 1, a main body 2 mounted on the base 1 for storing, boosting, and connecting to the grid, and a heat dissipation and dust prevention mechanism 3 mounted on the main body 2 for heat dissipation and dust prevention, the heat dissipation and dust prevention mechanism 3 including:

[0027] The ventilation assembly 31 includes several outer frames 311 mounted on the base 1, with a dustproof net 314 fixed to the inner end of each outer frame 311.

[0028] The control component 32 includes a frame 321 fixed to the inner end of the outer frame 311. Several blades 322 are rotatably mounted between the inner walls of both ends of the frame 321 and are distributed longitudinally at equal intervals. A bracket 323 is fixed to one end of each blade 322. A connecting rod 324 is pivotally connected between the brackets 323. A motor 325 is mounted on the outer wall of the frame 321 and is used to drive one of the blades 322 to rotate. A fan cover 33 is fixed on the frame 321 and a cooling fan 34 is installed inside the fan cover 33.

[0029] In this embodiment, when the internal temperature of the cabin 21 is high, one of the blades 322 is driven to rotate through the output of the motor 325. The blade 322 drives the other supports 323 to rotate through the bracket 323 and the connecting rod 324. The other supports 323 drive the corresponding blades 322 to rotate, thereby controlling each blade 322 to open synchronously, and cooperate with the cooling fan 34 and the ventilation assembly 31 to ventilate and dissipate heat. When the internal temperature of the cabin 21 is normal or not working, several blades 322 close synchronously, thereby preventing external dust from entering.

[0030] Specifically, the ventilation component 31 also includes an inner frame 312 fixed inside the outer frame 311, and a number of ventilation channels 313 are fixed inside the inner frame 312 and distributed longitudinally at equal intervals.

[0031] In this embodiment, the ventilation path is extended by a number of ventilation ducts 313 and guided into an S-shape, and then the dustproof net 314 is used to reduce the entry of external dust.

[0032] Specifically, the control component 32 also includes adhesive strips 326 fixed to the upper and lower outer surfaces of the blade 322.

[0033] In this embodiment, when several blades 322 rotate and close, adjacent blades 322 can be bonded together by adhesive strips 326, which improves the sealing between adjacent blades 322 after closing, and avoids direct collision and contact between blades 322 when they close by adhesive strips 326.

[0034] Specifically, the control component 32 also includes an upper baffle 327 fixed inside the upper part of the frame 321, and a lower baffle 328 fixed inside the lower part of the frame 321.

[0035] In this embodiment, when several blades 322 rotate and close, the uppermost and lowermost blades 322 can respectively fit against the upper baffle 327 and the lower baffle 328 to form a complete sealing surface, thereby improving the sealing performance between the blades 322 and the frame 321 after closing.

[0036] Specifically, the control component 32 also includes recesses 329 formed at the upper and lower ends inside the frame 321.

[0037] In this embodiment, when the uppermost and lowermost blades 322 rotate, the recessed portion 329 provides clearance space to ensure smooth opening and closing without jamming.

[0038] Specifically, the main structure 2 includes a cabin 21 fixed to the top of the base 1. A dry-type transformer 22 is installed at the right end inside the cabin 21. A high-voltage vacuum circuit breaker 23 is installed at the front left end inside the cabin 21. A high-voltage switch cabinet 24 is installed at the rear left end inside the cabin 21. A converter 25 is installed at the top right end of the base 1.

[0039] The working principle and usage process of this utility model are as follows: First, when the internal temperature of the cabin 21 is high, one of the blades 322 is driven to rotate through the output end of the motor 325. The blade 322 drives the other supports 323 to rotate through the bracket 323 and the connecting rod 324. The other supports 323 drive the corresponding blades 322 to rotate, thereby controlling each blade 322 to open synchronously, and ventilating and cooling in conjunction with the cooling fan 34 and the ventilation assembly 31. At the same time, the ventilation path is extended through several ventilation ducts 313 and guided into an S-shape, and the dustproof net 314 is used to reduce the entry of external dust.

[0040] When the internal temperature of the cabin 21 is normal or not in operation, several blades 322 close simultaneously. Adjacent blades 322 can be bonded together by adhesive strips 326, which improves the sealing between adjacent blades 322 after closure. In addition, the adhesive strips 326 prevent direct collision and contact between the blades 322 when they close. At the same time, the uppermost and lowermost blades 322 can be bonded to the upper baffle 327 and the lower baffle 328 respectively to form a complete sealing surface, which improves the sealing between the blades 322 and the frame 321 after closure, thereby preventing external dust from entering.
