Description

Technical Field

[0001] This utility model relates to the field of energy storage systems, and in particular to an exhaust structure for a high-capacity energy storage system. Background Technology

[0002] With the continuous growth of energy demand and the large-scale application of renewable energy, high-capacity energy storage systems play a crucial role in power supply, industrial production, and other fields. High-capacity energy storage systems generate a significant amount of heat during operation. If this heat cannot be dissipated in a timely and effective manner, it will severely impact the performance, lifespan, and safety of the energy storage system. Therefore, ventilation structure is of paramount importance for high-capacity energy storage systems.

[0003] Currently, existing high-capacity energy storage system exhaust structures have many problems. First, the exhaust ducts are fixed, which means they can only extract hot air from a specific direction. In practical applications, the heat distribution inside the energy storage system may not be uniform, and fixed ducts cannot flexibly adapt to different heat distribution conditions, resulting in poor exhaust performance. Second, existing exhaust vents only have dust filters. Although the dust filters can block some dust when not in use, they cannot completely seal the system, and dust can still easily enter. Over time, the accumulated dust inside can damage the energy storage system equipment and affect its normal operation. In addition, dust accumulation may also reduce the ventilation efficiency of the exhaust structure, further affecting the heat dissipation effect of the energy storage system.

[0004] Therefore, it is necessary to propose a ventilation structure for a high-capacity energy storage system to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide an exhaust structure for a high-capacity energy storage system, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A ventilation structure for a high-capacity energy storage system includes a cabinet, an exhaust duct located at one end inside the cabinet for extracting hot air from inside the cabinet, an exhaust port located at one end of the exhaust duct, and a dustproof net located outside the exhaust port. A hot air extraction mechanism is provided inside the exhaust duct.

[0008] The hot air extraction mechanism includes a motor located at the upper end of the inner side of the exhaust duct. The bottom output end of the motor is provided with a first rotating shaft driven by the motor to rotate. The upper end of the first rotating shaft is provided with an exhaust fan blade. An air inlet for hot air to enter is provided on one side of the lower end of the exhaust duct.

[0009] It also includes an airflow adjustment mechanism, which includes a second rotating shaft rotatably disposed inside the air inlet. A guide plate is fixedly disposed on the second rotating shaft. A gear is disposed at the end of the second rotating shaft. A rack that meshes with the gear is vertically movably connected to one side of the air inlet. A connecting frame is disposed on one side of the rack. A drive ring is disposed on the side of the connecting frame away from the rack. One end of the drive ring is a high point, and the other end is a low point, with a smooth transition between the high and low points. A horizontal arm is disposed at the bottom of the first rotating shaft. A fixing frame corresponding to the drive ring and located at the bottom of the drive ring is disposed on the inner wall of the exhaust duct. A spring is vertically disposed between the top of the fixing frame and the bottom of the drive ring.

[0010] Preferably, there are multiple air guide plates, and the multiple plates are evenly arranged along the height direction of the inner side of the air inlet.

[0011] Preferably, a guide rail corresponding to the rack is vertically arranged at one end of the inner side of the air inlet, and the rack is movably guided to the guide rail.

[0012] Preferably, one end of the cross arm is rotatably connected to a roller for rolling engagement with the top of the drive ring.

[0013] Preferably, a guide rod is vertically and movably connected to the fixing frame, and the spring is sleeved on the outside of the guide rod.

[0014] Preferably, a dust baffle is evenly provided vertically at the end of the exhaust vent away from the exhaust duct, and a third rotating shaft is fixedly provided at the upper end of the dust baffle, with the end of the third rotating shaft rotatably connected to the inner wall of the exhaust vent.

[0015] Compared with the prior art, this utility model provides an exhaust structure for a high-capacity energy storage system, which has the following advantages:

[0016] 1. This high-capacity energy storage system uses an exhaust structure. Through the set hot air extraction mechanism and the airflow adjustment mechanism, hot air from different directions inside the cabinet can be extracted. The motor drives the first rotating shaft to rotate, and at the same time, the angle of the guide plate is changed, thereby changing the airflow direction and improving the exhaust heat dissipation effect. The structure is compact and easy to use.

[0017] 2. The high-capacity energy storage system uses an exhaust structure, and the combination of the dust baffle and the third rotating shaft can automatically flip open under air pressure when in use, and automatically fall and close under its own weight when not in use, thus preventing dust from entering.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-5 As shown, a ventilation structure for a high-capacity energy storage system includes a cabinet 1, an exhaust duct 3 located at one end inside the cabinet 1 for extracting hot air from inside the cabinet 1, an exhaust port 4 located at one end of the exhaust duct 3, and a dustproof net 2 located outside the exhaust port 4. A hot air extraction mechanism is provided inside the exhaust duct 3.

[0026] The hot air extraction mechanism includes a motor 5 located at the upper end of the inner side of the exhaust duct 3. The bottom output end of the motor 5 is provided with a first rotating shaft 7 driven by the motor 5 to rotate. The upper end of the first rotating shaft 7 is provided with an exhaust fan blade 6. The lower end of the exhaust duct 3 is provided with an air inlet 10 for hot air to enter.

[0027] It also includes an airflow adjustment mechanism, which includes a second rotating shaft 11 rotatably disposed inside the air inlet 10. Multiple guide plates 9 are fixedly mounted on the second rotating shaft 11 and are evenly distributed along the height direction inside the air inlet 10. A gear 13 is provided at the end of the second rotating shaft 11. A rack 14 meshing with the gear 13 is vertically movably connected to one side of the air inlet 10. To increase stability, a guide rail 12 corresponding to the rack 14 is vertically provided at one end inside the air inlet 10. The rack 14 is movably guided and connected to the guide rail 12. A connecting frame 17 is provided on one side of the rack 14, and a drive ring is provided on the side of the connecting frame 17 away from the rack 14. 18, and one end of the drive ring 18 is a high point 19, and the other end is a low point 20, with a smooth transition between the high point 19 and the low point 20. A horizontal arm 15 is provided at the bottom of the first rotating shaft 7. In order to reduce friction, a roller 16 is rotatably connected at one end of the horizontal arm 15 for rolling cooperation with the top of the drive ring 18. A fixed frame 21 corresponding to the drive ring 18 and located at the bottom of the drive ring 18 is provided on the inner wall of the exhaust duct 3. In order to facilitate the reset of the rack 14, a spring 23 is vertically provided between the top of the fixed frame 21 and the bottom of the drive ring 18. In order to increase stability, a guide rod 22 is vertically movably connected on the fixed frame 21, and the spring 23 is sleeved on the outside of the guide rod 22.

[0028] In addition, in order to prevent dust from entering the cabinet 1, a dust baffle 24 is evenly arranged vertically at the end of the exhaust vent 4 away from the exhaust duct 3. A third rotating shaft 25 is fixedly installed at the upper end of the dust baffle 24, and the end of the third rotating shaft 25 is rotatably connected to the inner wall of the exhaust vent 4.

[0029] During operation, motor 5 drives the first rotating shaft 7 to rotate, which in turn drives the exhaust fan blades 6 to rotate. This creates negative pressure at the lower end of the exhaust duct 3, allowing hot air inside the cabinet 1 to enter through the air inlet 10 and exit through the exhaust outlet 4. During exhaust, the dust baffle 24 automatically flips open due to air pressure. The rotation of the first rotating shaft 7 also drives the rotation of the bottom cross arm 15. The cross arm 15 uses rollers 16 to raise and lower the drive ring 18. Specifically, when the roller 16 moves from the high point 19 to the low point 20, the spring 23... The reset mechanism drives the ring 18 to rise, which in turn causes the connecting frame 17 and rack 14 to rise as a whole. The rack 14 then drives the second rotating shaft 11 to rotate through the gear 13, thereby changing the angle of the guide plate 9. When the roller 16 moves from the low point 20 to the high point 19, the spring 23 contracts, the rack 14 rises, and the guide plate 9 flips in the opposite direction. As a result, the angle of the guide plate 9 changes continuously, which can extract hot air from different directions inside the cabinet 1. When not in use, the dust baffle 24 automatically flips and falls to a vertical position under its own weight.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
