Description

Technical Field

[0001] The present invention relates to the field of energy storage technology, and in particular to a new energy storage and power supply container. Background Art

[0002] Energy storage power supply container is an integrated energy storage device that realizes efficient storage and release of energy by integrating battery modules, intelligent converters, high-voltage control systems, etc. in one stop. It has the advantages of balancing grid load, peak load shifting, saving application space, and easy transportation, installation and maintenance. New energy storage power supply container is a device used to store and provide renewable energy. It can convert renewable energy such as solar energy, wind energy, and hydropower into electrical energy, and release electrical energy to supply power systems or other applications when needed.

[0003] In some scenarios, such as wind or solar power generation systems built in deserts and Gobi, the energy storage and power supply containers will be placed in windy and dusty environments. In this case, the existing containers are usually equipped with filtering equipment, which can prevent wind and sand from entering, and realize internal and external ventilation to dissipate heat for battery modules and electronic equipment in a timely manner.

[0004] However, when an emergency occurs, battery modules or electronic devices catch fire inside the container. Although the energy storage power supply container is equipped with a power-off and fire-extinguishing system, electrical fires are characterized by rapid and large fires, which means that it takes a long time for the fire-extinguishing system to completely extinguish the fire from the occurrence of the fire to the triggering of the system. During this period, other equipment may be ignited, causing losses to expand and triggering other chain reactions.

[0005] To this end, how to design a new energy storage power supply container so that it can autonomously cut off the ventilation path in an emergency, seal the air to isolate oxygen, and thus cooperate with other emergency systems to achieve rapid fire extinguishing is a technical problem that technicians in this field need to solve.

The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] The present invention provides a new energy storage power supply container 10, which is designed to cut off the ventilation path autonomously in an emergency without affecting the normal ventilation and heat dissipation, so as to close the air and isolate the oxygen, thereby cooperating with other emergency systems to achieve rapid fire extinguishing. Figure 1 As shown, the new energy storage power supply container 10 includes a box body 11 and a hood air filter device 12 , and the hood air filter device 12 is arranged on the top of the box body 11 .

[0036] Among them, Figure 2 and Figure 3 As shown, the hood air filter device 12 includes: a base 100, a shielding cap 200 and a filter assembly 300. The base 100 is fixedly mounted on the box body 11. Figure 4 As shown, a receiving cavity 110 is provided in the base 100, a ventilation window 120 communicating with the receiving cavity 110 is opened on the side wall of the base 100, a shielding cap 200 is rotatably covered on the outside of the base 100, and the filter assembly 300 is movably accommodated in the receiving cavity 110 through a pressure-limiting elastic member 400.

[0037] like Figure 4 As shown, a holding step 111 and a shielding plate 112 are provided in the accommodating cavity 110, and the shielding plate 112 is located on the top of the base 100. In normal situations, the filter assembly 300 will be pressed against the holding step 111 under the action of the pressure-limiting elastic member 400; in emergency situations, the filter assembly 300 will be attached to the shielding plate 112 under the action of the pressure-limiting elastic member 400.

[0038] like Figure 3 and Figure 5 As shown, the side wall of the shielding cap 200 is provided with a vent 210 and a shielding portion 220. In normal circumstances, the vent 210 is located at the position of the vent window 120 to achieve ventilation; in an emergency, the shielding portion 220 is located at the position of the vent window 120 to achieve blocking and airtightness.

[0039] In this embodiment, the ventilation portion 210 of the shielding cap 200 is a shutter structure (such as Figure 3 As shown). Under normal circumstances, when ventilation is performed, the external air needs to pass through the ventilation part 210, ventilation window 120 and filter assembly 300 of the shielding cap 200 in sequence before entering the interior. Among them, the filter assembly 300 is used to filter fine sand and dust. The arrangement of the ventilation part 210 and ventilation window 120 can prevent large-volume objects such as birds, animals and plant leaves from entering. Moreover, the shielding cap 200 can rotate. Driven by the external wind force, the rotating shielding cap 200 can effectively promote the circulation of air inside and outside, and throw away the obstructions such as sand, dust or leaves attached thereto through centrifugal force.

[0040] Preferably, a bearing (not shown) is provided between the shielding cap 200 and the base 100 to reduce the friction between the two during rotation. In normal situations, the shielding cap 200 is pressed on the base 100 by the bearing; in emergency situations, the shielding cap 200 is separated from the bearing.

[0041] In this embodiment, if Figure 6 and Figure 7 As shown, the filter assembly 300 includes: a housing 310, a pressing plate 320, a breathable membrane 330, a filter element 340 and a lifting member 350. The housing 310 is connected to the base 100 through a pressure-limiting elastic member 400. The pressing plate 320 presses the breathable membrane 330 on the housing 310. The pressing plate 320 is provided with a breathable hole 321. The housing 310 is provided with a filter chamber 311 for accommodating the filter element 340. The lifting member 350 is arranged above the pressing plate 320. In an emergency, the lifting member 350 will pass through the shielding plate 112 and lift up the shielding cap 200.

[0042] Preferably, Figure 7As shown, the filter element 340 includes: a fiber layer 341 for filtering larger impurities, a cotton layer 342 for filtering smaller impurities, and an activated carbon layer 343 for absorbing harmful gases. The fiber layer 341, the activated carbon layer 343 and the cotton layer 342 are arranged in sequence from top to bottom.

[0043] Preferably, Figure 6 and Figure 7 As shown, the pressure-limiting elastic member 400 is a torsion spring structure, and the two ends of the pressure-limiting elastic member 400 are respectively hinged on the housing 310 and the base 100. There are multiple pressure-limiting elastic members 400, and the multiple pressure-limiting elastic members 400 are distributed around the housing 310 in an annular array.

[0044] Next, in combination with the above structure, the working principle of the hood air filter device 12 of the present invention is described. Figure 8 and Fig. 9 As shown:

[0045] The hood air filter device 12 serves as a connection channel for the gas inside and outside the new energy storage power supply container 10, which divides the container 10 into an interior and an exterior;

[0046] Under normal circumstances, the hood filter device 12 mainly plays a role in ventilation. Figure 8 As shown, the vent portion 210 of the shielding cap 200 is located at the position of the vent window 120, the filter assembly 300 is pressed on the holding step 111, and the pressure-limiting elastic member 400 provides a downward elastic force for the filter assembly 300. The shielding cap 200 can rotate under the drive of external wind force, thereby promoting the circulation of air inside and outside. At this time, the external air needs to pass through the vent portion 210, the vent window 120 and the filter assembly 300 of the shielding cap 200 in sequence before entering the interior; in this process, the sand and dust mixed in the external air will be filtered by the filter assembly 300, so as not to pollute the internal electronic equipment;

[0047] In an emergency, the hood filter device 12 mainly plays the role of blocking air to isolate oxygen. Fig. 9As shown, in an emergency, a fire occurs in the internal electronic equipment, the internal temperature and air pressure increase rapidly, and the filter assembly 300 is affected by the air pressure and generates an upward thrust. After reaching a certain critical value, the thrust will prompt the pressure-limiting elastic member 400 to flip upward. At this time, the elastic force provided by the flipped elastic member 400 to the filter assembly 300 is upward, and then the filter assembly 300 is pushed upward so that it fits on the baffle plate 112, that is, the filter assembly 300 moves up from the holding step 111 to the baffle plate 112. At this moment, the baffle plate 112 will block the upper surface of the filter assembly 300, so that the gas can no longer pass through the filter assembly 300. At the same time, during the upward movement, the lifting member 350 of the filter assembly 300 will pass through the baffle plate 112 and lift the shielding cap 200, so that the shielding portion 220 of the shielding cap 200 is at the position of the ventilation window 120. In this way, the ventilation window 120 is closed, the path of gas flow inside and outside is cut off, and a relatively closed space is formed inside the container 10. Since there is no oxygen supplement, the fire inside will be effectively contained, and with the intervention and cooperation of other fire extinguishing systems in the container 10, the fire will be quickly extinguished.

[0048] That is to say, compared with the filtering device of the prior art, the hood air filter device 12 of the present invention has two different states to adapt to different working conditions. In normal working conditions, the hood air filter device 12 has the same function as the filtering device of the prior art, both of which realize ventilation and air permeability, and the shielding cap 200 can rotate under the action of wind, which can further promote internal heat dissipation; in an emergency, the hood air filter device 12 plays a role of sealing air, which forms a closed space inside the container 10, thereby preventing internal flames from burning.

[0049] It should be noted that in an emergency, the upward movement of the filter assembly 300 can not only push the shielding cap 200 upward, but also keep the filter assembly 300 away from the fire source to avoid damage to the filter assembly 300. Moreover, the structural characteristics and connection relationship of the pressure-limiting elastic member 400 make it difficult to reset after being turned up and deformed, that is, the filter assembly 300 will remain in the current position after being moved up, and will not be reset. The reason for this design is mainly due to the following considerations: for the interior of the container 10 that has just completed the fire extinguishing, the electrical equipment at this time is still at a relatively high temperature. If oxygen (air) can be introduced, it is easy to re-ignite; and the filter assembly 300 of the present invention does not reset after being moved up, so that the shielding cap 200 can always remain in the upward position without falling back. In this way, the shielding portion 220 always blocks the ventilation window 120, and the interior of the container 10 will be in an oxygen-free or oxygen-deficient state for a long time, thereby preventing the flame from re-igniting.

[0050] It is worth emphasizing that, under normal circumstances, the battery modules and electronic devices inside the container 10 will also generate heat when working together, causing the internal air pressure to rise in a short period of time. At this time, the air pressure will also provide an upward thrust to the filter assembly 300. This thrust will overcome the elastic force of the pressure-limiting elastic member 400 (the pressure-limiting elastic member 400 is not turned up), so that the filter assembly 300 is lifted a short distance. In this way, the internal high-pressure gas can be quickly discharged from the gap between the shell 310 and the substrate 100 without passing through the filter assembly 300. After the internal air pressure is reduced, the filter assembly 300 will be reset under the action of the elastic force and re-pressed on the clamping step 111. In other words, the internal air pressure can only increase to a thrust that exceeds the critical value, which can cause the pressure-limiting elastic member 400 to turn upward. For the pressure rise under normal circumstances, the filter assembly 300 can be adaptively lifted and automatically reset to achieve rapid exhaust and prevent dust from entering.

[0051] In this embodiment, the lifting member 350 is a cylindrical spring structure (such as Figure 6 As shown in the figure, one end of the lifting member 350 is fixed on the pressure plate 320, and the other end of the lifting member 350 points to the shielding cap 200. The shielding plate 112 is provided with an avoidance hole 113 adapted to the lifting member 350. The lifting member 350 of the cylindrical spring structure can provide better buffering while achieving the lifting effect to reduce the rigid collision with the shielding plate 200. In other embodiments, the lifting member 350 can be a cylindrical rod structure, the end of the lifting member 350 is fixed on the pressure plate 320, and the lifting member 350 is passed through the shielding plate 112. When the filter assembly 300 moves up, it can also push the shielding cap 200 to rise to achieve the lifting effect.

[0052] Preferably, an elastic gasket (not shown) is provided on the shielding portion 220 of the shielding cap 200, and in an emergency, the elastic gasket will block the ventilation window 120. A sealing ring (not shown) is provided on the side wall of the base 100, and the sealing ring is located above the ventilation window 120. When the shielding portion 220 blocks the ventilation window 120, the sealing ring can enhance air tightness and achieve a better sealing effect.

[0053] In summary, the new energy storage power supply container 10 of the present invention can autonomously cut off the ventilation path in an emergency state, achieve airtightness to isolate oxygen, and thus cooperate with other emergency systems to achieve rapid fire extinguishing.

[0054] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
