Description
Technical Field
[0001] This invention relates to the field of battery manufacturing technology, and specifically to an energy storage cabinet. Background Technology
[0002] The energy storage cabinet contains batteries and charging / discharging electrical components for energy storage. During use, the charging and discharging of the batteries inside the cabinet generates heat, causing the temperature inside the cabinet to rise. Currently, ventilation openings are usually provided on the cabinet body to facilitate the dissipation of heat. However, the heat dissipation efficiency of ventilation openings is relatively low. Especially when multiple high-power battery packs are installed inside the energy storage cabinet, simultaneous operation in hot weather can easily cause the internal temperature of the energy storage cabinet to rise rapidly. If the heat inside the energy storage cabinet is not dissipated in time, it can easily affect the normal operation of the electrical components inside the cabinet, greatly increasing the failure rate of the equipment. Summary of the Invention
[0003] The purpose of this invention is to provide an energy storage cabinet that can effectively solve the technical problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: An energy storage cabinet includes an energy storage cabinet body and an adjustment component. The energy storage cabinet body is equipped with a cabinet door, has ventilation holes on its side walls, and a temperature sensor for monitoring the internal temperature of the energy storage cabinet body. A vent hole is located on the top, and a first safety component is installed at the vent hole. The first safety component includes a positioning ring, a blower, and a sealing airbag. The positioning ring is positioned above the vent hole, and a gap is provided between the positioning ring and the vent hole. The sealing airbag is made of a soft material and surrounds the outside of the positioning ring. The sealing airbag is connected to a hollow sealing cover plate via an airbag flow channel. The sealing cover plate is positioned on the positioning ring and seals the inner hole of the positioning ring. The interiors of the sealing airbag, the airbag flow channel, and the sealing cover plate are all interconnected. The sealing cover plate is connected to a blower pipe via a telescopic air duct, and the blower pipe is connected to the blower. The adjustment component is used to adjust the gap between the positioning ring and the vent hole. The induced draft fan operates in the forward direction, and the airflow sequentially enters the sealed airbag through the induced draft pipe, the sealing cover plate, and the airbag channel until the sealed airbag inflates and its bottom presses firmly against the top of the energy storage cabinet, sealing the gap between the positioning ring and the vent hole. At this point, the valve on the induced draft pipe closes and the induced draft fan stops operating (the pressure sensor detects the air pressure inside the sealed airbag and controls the induced draft fan to stop). When the temperature sensor detects the set temperature inside the energy storage cabinet, the valve on the induced draft pipe opens and the induced draft fan reverses its direction, allowing air to flow out of the sealed airbag until it contracts and a gap appears between the positioning ring and the vent hole, allowing the gas inside the energy storage cabinet to flow out rapidly. When a gap appears between the positioning ring and the vent hole, and the temperature sensor detects that the temperature inside the energy storage cabinet has continuously reached the set value and exceeded the set time, the second safety component activates and the vent hole opens.
[0005] Preferably, the adjustment assembly includes a first slider, a limiting support rod, and a positioning plate. The positioning plate is located below the sealing cover plate, and its two ends are connected to a first fixing block via connecting plates. The first fixing block is connected to the inner wall of the energy storage cabinet. A second return spring is provided between the positioning plate and the sealing cover plate. A limiting support rod is provided at the bottom of the positioning ring. The lower end of the limiting support rod passes through a first through hole on the first slider. A sliding groove is provided at the top of the first slider, and a second through hole and a threaded through hole are provided on the side wall. A second slider is provided in the sliding groove. A guide post and a locking bolt are respectively provided in the second through hole and the threaded through hole. One end of the guide post is connected to the second slider. Adjusting the locking bolt causes the locking bolt to push the second slider to slide along the sliding groove until the arc surface of the second slider presses against the limiting support rod. The first slider is installed on the energy storage cabinet.
[0006] Preferably, the second safety component includes a power cylinder, a first guide rail, and a second guide rail. The first guide rail is disposed on the top inner wall of the energy storage cabinet. A first guide groove on the first slider is installed on the first guide rail. A push block is connected to the power telescopic rod at the output end of the power cylinder. The push block presses against a limiting block. The limiting block is connected to the bottom of the first slider. A second guide rail is disposed at the bottom of the positioning ring. A first limiting piece and a second limiting piece are disposed at both ends of the second guide rail. A second guide groove at the top of the limiting support rod is installed on the second guide rail. A first return spring is disposed between the first limiting piece and the limiting support rod. The first return spring presses the limiting support rod against the second limiting piece. The power cylinder pushes the first slider to move along the first guide rail. At the same time, the first return spring contracts and the limiting support rod moves along the second guide rail until the first slider disengages from the first guide rail and is completely below the vent hole. Then, the second return spring pushes the sealing cover plate upward to open the vent hole.
[0007] Preferably, the second reset springs are distributed in a circular array on the positioning disk.
[0008] Preferably, the central axis of the positioning ring and the central axis of the vent hole are located on the same straight line.
[0009] Preferably, the first guide rail has a T-shaped cross-section and the second guide rail has an L-shaped cross-section.
[0010] Preferably, the bottom of the sealing cover is provided with a limiting ring, and the bottom of the limiting ring is provided with a limiting groove, which engages with the positioning ring.
[0011] Preferably, the bottom of the energy storage cabinet is provided with a plurality of support components for adjusting the height. The support components include a fixed stud and a sliding foot. The fixed stud is connected to the bottom of the energy storage cabinet. The upper adjusting sleeve of the sliding foot is threaded to the fixed stud, and the lower foot boss is provided on the support surface.
[0012] Preferably, the energy storage cabinet has mounting holes on its side wall, and a guide fan is installed in the mounting holes.
[0013] Preferably, the vents are located on the lower part of the side wall of the energy storage cabinet and are distributed in a rectangular array on the energy storage cabinet.
[0014] Compared with the prior art, the beneficial effects of the present invention are: In cold weather, when the heat dissipation inside the energy storage cabinet is sufficient, the exhaust fan operates in the forward direction. Airflow sequentially enters the sealed airbag through the exhaust duct, sealing cover, and airbag channel until the sealed airbag inflates. The bottom of the inflated airbag presses firmly against the top of the energy storage cabinet, sealing the gap between the positioning ring and the vent hole. Once the pressure sensor detects that the air pressure inside the sealed airbag has reached the set value, the exhaust fan stops operating, and the valve on the exhaust duct closes. However, in hot weather, multiple battery packs inside the energy storage cabinet operate simultaneously, causing the temperature inside the cabinet to rise rapidly. When the temperature sensor detects that the internal temperature of the energy storage cabinet has reached the set value, the valve on the exhaust duct opens, and the exhaust fan reverses its direction, allowing air to flow into the sealed airbag. Air flows out until the sealed airbag contracts and a gap appears between the positioning ring and the vent hole. At this time, the heat inside the energy storage cabinet can quickly flow out through the gap, accelerating the heat dissipation effect inside the energy storage cabinet to avoid the electrical components inside the energy storage cabinet from being affected by excessive temperature. When it is necessary to adjust the heat dissipation effect, the positioning ring can be moved vertically to a suitable position, and the limiting support can be moved along the first through hole on the first slider until the gap between the positioning ring and the vent hole meets the requirements. Then, the locking bolt is adjusted so that the locking bolt pushes the second slider to slide along the sliding groove until the arc surface of the second slider is pressed against the limiting support, preventing the limiting support from moving arbitrarily along the first through hole on the first slider. When a gap appears between the positioning ring and the vent hole, and the temperature sensor still detects that the temperature inside the energy storage cabinet continues to reach the set value and exceeds the set time, the power cylinder pushes the first slider to move along the first guide rail. At the same time, the first return spring contracts and the limit support rod moves along the second guide rail until the first slider disengages from the first guide rail and is completely below the vent hole. Then, the second return spring pushes the sealing cover plate upward to open the vent hole, allowing the temperature inside the energy storage cabinet to be discharged through the vent hole, thus preventing damage to the electrical components inside the energy storage cabinet due to prolonged high temperature.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0017] Please see Figure 1-7 As shown, an energy storage cabinet includes an energy storage cabinet body and an adjustment assembly. The energy storage cabinet body 1 is equipped with a cabinet door 2, and has ventilation holes 3 on its side walls. A temperature sensor for monitoring the internal temperature of the energy storage cabinet body 1 is installed inside. A vent hole 4 is opened at the top. A first safety component is installed at the vent hole 4. The first safety component includes a positioning ring 5, a fan 6, and a sealing airbag 7. The positioning ring 5 is positioned above the vent hole 4, and a gap is provided between the positioning ring 5 and the vent hole 4. The sealing airbag 7 is made of soft material and surrounds the outside of the positioning ring 5. The sealing airbag 7 flows through an airbag channel. 8 is connected to a sealing cover plate 9 with a hollow internal structure. The sealing cover plate 9 is set on the positioning ring 5 and seals the inner hole on the positioning ring 5. The airbag 7, the airbag flow channel 8 and the interior of the sealing cover plate 9 are all connected. The sealing cover plate 9 is connected to the air duct 11 through the telescopic air duct 10. The air duct 11 is connected to the blower 6. The adjustment component is used to adjust the gap between the positioning ring 5 and the vent hole 4. The telescopic air duct 10 can be made of plastic or cloth material. When the sealing cover plate 9 moves upward, the telescopic air duct 10 can be contracted under the action of the sealing cover plate 9 without affecting the air duct 11. The central axis of the positioning ring 5 and the central axis of the vent hole 4 are on the same straight line; The induced draft fan 6 operates in the forward direction, and the airflow sequentially enters the sealed airbag 7 through the induced draft pipe 11, the sealing cover plate 9, and the airbag flow channel 8. The airflow continues until the sealed airbag 7 inflates and its bottom presses firmly against the top of the energy storage cabinet 1, sealing the gap between the positioning ring 5 and the vent hole 4. At this point, the pressure sensor detects that the air pressure inside the sealed airbag 7 has reached the corresponding set value, and the induced draft fan stops operating, and the valve on the induced draft pipe 11 closes. During use, when the temperature sensor detects the set internal temperature of the energy storage cabinet 1, the induced draft fan stops operating. The valve on the duct 11 is opened and the induced draft fan 6 is reversed. The air in the sealed airbag 7 flows out until the sealed airbag 7 contracts and a gap appears between the positioning ring 5 and the vent hole 4 so that the gas inside the energy storage cabinet 1 can flow out quickly. When a gap appears between the positioning ring 5 and the vent hole 4, the temperature sensor detects that the temperature inside the energy storage cabinet 1 continues to reach the set value and exceeds the set time. In order to prevent the electrical components inside the energy storage cabinet 1 from working at a high temperature for a long time, the second safety component is activated and the vent hole 4 is opened. The adjustment assembly includes a first slider 12, a limiting support rod 13, and a positioning plate 14. The positioning plate 14 is located below the sealing cover plate 9, and its two ends are connected to a first fixing block 16 via connecting plates 15. The first fixing block 16 is connected to the inner wall of the energy storage cabinet 1. A second return spring 17 is provided between the positioning plate 14 and the sealing cover plate 9. The bottom of the positioning ring 5 is provided with a limiting support rod 13, and the lower end of the limiting support rod 13 passes through a first through hole on the first slider 12. The top of the 2 is provided with a sliding groove 18, and the side wall is provided with a second through hole and a threaded through hole. A second slider 19 is provided in the sliding groove 18. A guide post 20 and a locking bolt 21 are respectively provided in the second through hole and the threaded through hole. One end of the guide post 20 is connected to the second slider 19. Adjusting the locking bolt 21 causes the locking bolt 21 to push the second slider 19 to slide along the sliding groove 18 until the arc surface of the second slider 19 is pressed against the limiting support rod 13. The first slider 12 is installed on the energy storage cabinet 1. The second safety component includes a power cylinder 22, a first guide rail 23, and a second guide rail 24. The first guide rail 23 is disposed on the top inner wall of the energy storage cabinet 1. The first guide groove on the first slider 12 is mounted on the first guide rail 23. The power telescopic rod at the output end of the power cylinder is connected to a push block 25. The push block 25 presses against a limiting block 26. The limiting block 26 is connected to the bottom of the first slider 12. The bottom of the positioning ring 5 is provided with a second guide rail 24. The two ends of the second guide rail 24 are respectively provided with a first limiting piece 27 and a second limiting piece 28. The second guide groove at the top of the support rod 13 is installed on the second guide rail 24. A first return spring 29 is provided between the first limiting plate 27 and the limiting support rod 13. The first return spring 29 presses the limiting support rod 13 onto the second limiting plate 28. The power cylinder 22 pushes the first slider 12 to move along the first guide rail 23. At the same time, the first return spring 29 contracts and the limiting support rod 13 moves along the second guide rail 24 until the first slider 12 disengages from the first guide rail 23 and is completely below the vent hole 4. Then, the second return spring 17 pushes the sealing cover plate 9 upward to open the vent hole 4. The second reset springs 17 are arranged in a circular array on the positioning disk 14; The first guide rail 23 has a T-shaped cross-section, and the second guide rail 24 has an L-shaped cross-section. The bottom of the sealing cover plate 9 is provided with a limiting ring, and the bottom of the limiting ring is provided with a limiting groove, which engages with the positioning ring 5. The bottom of the energy storage cabinet 1 is provided with multiple support components for adjusting the height. The support components include a fixed stud 30 and a sliding foot 31. The fixed stud 30 is connected to the bottom of the energy storage cabinet 1. The upper adjusting sleeve 32 of the sliding foot 31 is threadedly connected to the fixed stud 30, and the lower foot boss is provided on the support surface. The energy storage cabinet 1 has mounting holes on its side wall, and a guide fan 33 is installed in the mounting holes; The ventilation holes 3 are located on the lower part of the side wall of the energy storage cabinet 1 and are distributed in a rectangular array on the energy storage cabinet 1.
[0018] In cold weather, when the heat dissipation inside the energy storage cabinet 1 is sufficient, the exhaust fan 6 operates in the forward direction. Airflow sequentially enters the sealed airbag 7 through the exhaust pipe 11, the sealing cover plate 9, and the airbag flow channel 8, until the sealed airbag 7 inflates. The bottom of the inflated sealed airbag 7 presses tightly against the top of the energy storage cabinet 1, sealing the gap between the positioning ring 5 and the vent hole 4. When the pressure sensor detects that the air pressure inside the sealed airbag 7 has reached the set value, the exhaust fan 6 stops operating, and the valve on the exhaust pipe 11 closes. However, in hot weather, multiple battery packs inside the energy storage cabinet 1 operate simultaneously, causing the temperature inside the energy storage cabinet 1 to rise rapidly. When the temperature sensor detects that the internal temperature of the energy storage cabinet 1 has reached the set value, the valve on the exhaust pipe 11 opens, and the exhaust fan 6 operates in the reverse direction, releasing air from the sealed airbag 7. The heat flows out until the sealed airbag 7 contracts and a gap appears between the positioning ring 5 and the vent hole 4. At this time, the heat inside the energy storage cabinet 1 can quickly flow out through the gap, accelerating the heat dissipation effect inside the energy storage cabinet 1 to avoid the temperature from being too high and affecting the normal operation of the electrical components inside the energy storage cabinet 1. When it is necessary to adjust the heat dissipation effect, the positioning ring 5 can be moved to a suitable position in the vertical direction. At the same time, the limiting support 13 moves along the first through hole on the first slider 12 until the gap between the positioning ring 5 and the vent hole 4 meets the requirements. Then, the locking bolt 21 is adjusted so that the locking bolt 21 pushes the second slider 19 to slide along the sliding groove 18 until the arc surface of the second slider 19 presses against the limiting support 13 to prevent the limiting support 13 from moving arbitrarily along the first through hole on the first slider 12. When a gap appears between the positioning ring 5 and the vent hole 4, and the temperature sensor still detects that the temperature inside the energy storage cabinet 1 continues to reach the set value and exceeds the set time, the power cylinder 22 pushes the first slider 12 to move along the first guide rail 23. At the same time, the first return spring 29 contracts and the limiting support rod 13 moves along the second guide rail 24 until the first slider 12 disengages from the first guide rail 23 and is completely below the vent hole 4. Then, the second return spring 17 pushes the sealing cover plate 9 upward to open the vent hole 4, allowing the temperature inside the energy storage cabinet 1 to be discharged through the vent hole, thus preventing the electrical components inside the energy storage cabinet 1 from being damaged due to prolonged high temperature.
[0019] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the present invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
