Description

Technical Field

[0001] The present disclosure relates to the technical field of fire protection of energy storage stations, and in particular to an energy storage station and a fire protection structure thereof. Background Art

[0002] The multiple battery clusters of the energy storage station are arranged in a sealed shell, which is prone to fire accidents and poses a great safety hazard. Therefore, in order to improve the safety of the use of the energy storage station, for example, the Chinese patent document CN 210472840 U discloses a fire prevention and control device for a lithium-ion battery energy storage system. By adding a fire extinguishing agent storage device, the fire detection device installed in the battery box can quickly and accurately detect the fire, and transmit the fire signal to the electrical control device in time. The electrical control device links the air duct shut-off valve to close, opens the selection valve, and starts the fire extinguishing system. The fire extinguishing agent reaches the battery box where the accident occurs in a timely and accurate manner through the delivery pipeline, quickly extinguishes the fire and effectively cools the battery. The fire extinguishing agent reaches the battery box where the accident occurs in a timely and accurate manner through the delivery pipeline, quickly extinguishes the fire and effectively cools the battery.

[0003] However, in actual applications, since the fire extinguishing agent is usually a gas such as heptafluoropropane, perfluorohexanone, carbon dioxide, etc., when the fire extinguishing agent is sprayed onto the surface of the battery cluster or the surface of the shell, residue will occur and damage the surface of the battery cluster or the surface of the shell, thereby affecting the secondary use of the energy storage station; in addition, when the above-mentioned fire extinguishing agent storage device is used, the fire extinguishing agent is prone to make loud noises during the fire extinguishing process, such as firecrackers.

[0004] In order to solve the above technical problems, some scholars have developed a new type of fireproof structure. As Chinese patent document CN113241492A discloses a container-type energy storage battery station with flame retardant and fire extinguishing functions, the box body is divided into fireproof isolation chambers, each fireproof isolation chamber includes: a fireproof isolation chamber bottom wall and four lateral fire walls respectively arranged on the front, back, left and right sides of the fireproof isolation chamber bottom wall, the four lateral fire walls and the fireproof isolation chamber bottom wall form a closed space for accommodating cooling water; the top of each fireproof isolation chamber is open, and each fire wall includes: two layers of steel plates and a flame retardant material sandwiched between the two layers of steel plates, the material of the flame retardant material layer is fire-retardant rock wool, thereby effectively avoiding problems such as high noise during the fire extinguishing process.

[0005] However, in the above-mentioned energy storage battery station, since the flame retardant material sandwiched between the two layers of steel plates is fire-retardant rock wool, the structural strength is relatively low. When it is in a fire, it is very easy to expand and deform due to the high temperature. In severe cases, it will collapse and expand the area of ​​the fire, causing greater losses. In addition, since the firewall of the above-mentioned energy storage battery station is fixedly connected, it is impossible to replace the damaged firewall separately, resulting in high maintenance costs.

DETAILED DESCRIPTION

[0033] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present disclosure are given in the drawings. However, the present disclosure 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 disclosure more thoroughly and comprehensively understood.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. 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.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0037] like Figures 1 to 3 As shown, the fireproof structure 10 of the energy storage station of one embodiment includes a fireproof box and a plurality of fireproof partitions, a accommodating cavity 110 is formed in the box, and the fireproof box is an inorganic high-temperature resistant fireproof box 100; the energy storage station 1 and its fireproof structure also include a metal skeleton 200; the metal skeleton 200 is arranged in the accommodating cavity 110, and is threadedly connected to the inorganic high-temperature resistant fireproof box 100; the fireproof partitions are inorganic high-temperature resistant fireproof partitions 300, and each of the inorganic high-temperature resistant fireproof partitions 300 is sequentially spaced and clamped on the side wall of the accommodating cavity 110, and divides the accommodating cavity 110 into a plurality of battery compartments 113.

[0038] It can be understood that since fire-retardant rock wool is usually made of organic material, it has poor structural strength and is prone to expansion and deformation due to heat. Compared with the inorganic high-temperature resistant fireproof box 100 and the inorganic high-temperature resistant fireproof partition 300 made of inorganic materials, since the inorganic materials themselves have good structural strength and are not easy to expand, the inorganic high-temperature resistant fireproof box 100 and the inorganic high-temperature resistant fireproof partition 300 can still maintain a good structural shape during a fire, and are not prone to expansion or even collapse, which effectively prevents the spread of flames to a larger area, thereby reducing greater losses.

[0039] Furthermore, since the metal skeleton 200 is arranged in the accommodating cavity 110 and is threadedly connected to the inorganic high-temperature resistant fireproof box 100, the inorganic high-temperature resistant fireproof box 100 and the metal skeleton 200 are detachably arranged. On the one hand, the added metal skeleton 200 can provide better support and fixation for the fireproof box, effectively avoiding the problem of collapse and deformation of the fireproof box during long-term use; on the one hand, it is convenient for the operator to disassemble and assemble the fireproof box, and the damaged fireproof box can be replaced separately, thereby reducing the maintenance cost; on the other hand, since a hollow area 210 is formed in the metal skeleton 200, it ensures that the inorganic high-temperature resistant fireproof box 100 can be more comprehensively exposed, so as to achieve rapid fireproof and heat-insulating performance of the battery cluster 20, and effectively avoid the volatilization of the fireproof and heat-insulating performance of the fireproof box being interfered with by the addition of the metal skeleton 200.

[0040] Furthermore, since the fireproof partition is an inorganic high-temperature resistant fireproof partition 300, each of the inorganic high-temperature resistant fireproof partitions 300 is sequentially spaced and clamped on the side wall of the accommodating cavity 110, and the accommodating cavity 110 is divided into multiple battery compartments 113; the inorganic high-temperature resistant fireproof partition 300 and the fireproof box are detachably arranged, which is convenient for the operator to disassemble and assemble, and the operator can replace the damaged inorganic high-temperature resistant fireproof partition 300 separately, further reducing the maintenance cost, and the multiple battery compartments 113 realize the separate partitioning of the accommodating cavity 110, thereby realizing fire prevention of multiple battery clusters 20, effectively avoiding the spread of flames in adjacent battery compartments 113, so as to better reduce fire losses.

[0041] In addition, the inorganic high temperature resistant fireproof partition 300 can provide more reliable support for the interior of the accommodating cavity 110, effectively preventing the energy storage station 1 from collapsing and deforming during long-term use or during a fire.

[0042] like Figure 3 As shown, in this embodiment, the metal skeleton 200 includes a plurality of metal longitudinal bars and a plurality of metal cross bars, and each of the metal longitudinal bars and each of the metal cross bars are staggered to form a plurality of hollow areas 210 to ensure that the inorganic high temperature resistant fireproof box 100 can be more fully exposed, and at the same time, the plurality of longitudinal bars and the plurality of cross bars can provide better structural support for the inorganic high temperature resistant fireproof box 100. Specifically, each of the plurality of longitudinal bars and each of the cross bars are arranged along the surrounding walls of the accommodating cavity 110, and are threadedly connected to the inorganic high temperature resistant fireproof box 100 through screws.

[0043] In a preferred embodiment, the inorganic high temperature resistant fireproof box 100 is a sulfur-magnesium inorganic composite box; to ensure that the inorganic high temperature resistant fireproof box 100 can still maintain a good structural shape during a fire, and is not prone to expansion or even collapse. Similarly, in one embodiment, the inorganic high temperature resistant fireproof partition 300 is a sulfur-magnesium inorganic composite partition, to ensure that the inorganic high temperature resistant fireproof partition 300 can still maintain a good structural shape during a fire, and is not prone to expansion or even collapse. Of course, those skilled in the art can also choose other known inorganic materials to ensure that the inorganic high temperature resistant fireproof box 100 and the inorganic high temperature resistant fireproof partition 300 have the same characteristics, so no specific limitation is made here.

[0044] It should be noted that the formulas of the magnesium-sulfide inorganic composite box and the magnesium-sulfide inorganic composite partition are both prior art and can be prepared by Chinese patent documents CN109369141A and CN115286352A, and are not within the scope of protection of the present disclosure. Therefore, the present disclosure only protects the connection relationship and position relationship between the magnesium-sulfide inorganic composite box and the magnesium-sulfide inorganic composite partition.

[0045] like Figure 4 As shown, in one embodiment, the top side wall and the bottom side wall of the accommodating cavity 110 are respectively formed with a first snap-fit ​​groove 111 and a second snap-fit ​​groove 112, and the inorganic high-temperature resistant fireproof partition 300 is respectively snap-fitted into the first snap-fit ​​groove 111 and the second snap-fit ​​groove 112 to realize the snap-fitting arrangement of the inorganic high-temperature resistant fireproof partition 300 and the side wall of the accommodating cavity 110.

[0046] like Figure 4 As shown, in one embodiment, the energy storage station 1 and its fireproof structure further include a first elastic sealing fireproof strip 400, which is disposed between the first engaging groove 111 and the first end of the inorganic high temperature resistant fireproof baffle 300. The additional first elastic sealing fireproof strip 400 improves the sealing performance between the inorganic high temperature resistant fireproof baffle 300 and the first engaging groove 111, effectively preventing the flame from spreading and the temperature from being transferred between the adjacent battery compartments 113.

[0047] Similarly, in order to better reduce the flame spread and temperature transfer between adjacent battery compartments 113, as Figure 4 As shown, in one embodiment, the energy storage station 1 and its fire protection structure also include a second elastic sealing fire protection strip 500, and the second elastic sealing fire protection strip 500 is arranged between the second snap-fit ​​groove 112 and the second end of the inorganic high temperature resistant fire protection partition 300.

[0048] like Figure 4As shown, in one embodiment, the first elastic sealing fireproof strip 400 is embedded in the first clamping groove 111, so as to realize the connection setting between the first elastic sealing fireproof strip 400 and the side wall of the first clamping groove 111; the first elastic sealing fireproof strip 400 forms a sealed plug-in cavity, and the inorganic high temperature resistant fireproof baffle 300 is sealed against the sealed plug-in cavity, so as to realize the sealed clamping setting between the inorganic high temperature resistant fireproof baffle 300 and the first elastic sealing fireproof strip 400. Similarly, the second elastic sealing fireproof strip 500 also has a structure similar to the first elastic sealing fireproof strip 400.

[0049] like Figure 4 As shown, in one embodiment, a first wedge-shaped plug-in portion 310 is formed at the first end of the inorganic high temperature resistant fireproof partition 300. The additional wedge-shaped plug-in portion is conducive to the operator to quickly disassemble and assemble the inorganic high temperature resistant fireproof partition 300, and at the same time, the second wedge-shaped plug-in portion 320 is formed at the second end of the inorganic high temperature resistant fireproof partition 300, which is more conducive to the operator to quickly disassemble and assemble the inorganic high temperature resistant fireproof partition 300.

[0050] like Figure 4 As shown, in one embodiment, the energy storage station 1 and its fireproof structure also include a first locking member 600, the first engaging groove 111 is provided with a first threaded hole 1111, the first locking member 600 passes through the first threaded hole 1111, and abuts against the side wall of the first end of the inorganic high temperature resistant fireproof partition 300, and the additional first locking member 600 realizes a more reliable fixation of the first end of the inorganic high temperature resistant fireproof partition 300, and effectively avoids the problem of loosening and falling off of the inorganic high temperature resistant fireproof partition 300 due to a large fire.

[0051] Likewise, if Figure 4 As shown, in one embodiment, the energy storage station 1 and its fireproof structure further include a second locking member 700, the second engaging groove 112 is provided with a second threaded hole, the second locking member 700 passes through the second threaded hole, and abuts against the side wall of the second end of the inorganic high temperature resistant fireproof baffle 300. The additional second locking member 700 achieves a more reliable fixation of the second end of the inorganic high temperature resistant fireproof baffle 300, and effectively avoids the problem that the inorganic high temperature resistant fireproof baffle 300 is easy to loosen and fall off due to a large fire.

[0052] In this embodiment, the first locking member 600 and the second locking member 700 are both screws.

[0053] In one embodiment, the second snap-fit ​​groove 112 and the first snap-fit ​​groove 111 both have an insertion port, which is located on the side of the second snap-fit ​​groove 112 facing away from the inorganic high-temperature resistant fireproof box body 100 or the side of the first snap-fit ​​groove 111 facing away from the inorganic high-temperature resistant fireproof box body 100, so that the operator can quickly install the inorganic high-temperature resistant fireproof partition 300.

[0054] like Figure 1 to Figure 2 As shown, the present disclosure also provides an energy storage station 1, including the fireproof structure 10 of the energy storage station described in any of the above embodiments. The energy storage station 1 also includes a plurality of battery clusters 20, each of which is arranged in a corresponding battery compartment 113, so that the additional inorganic high temperature resistant fireproof box 100 and a plurality of inorganic high temperature resistant fireproof partitions 300 can provide a better fireproof and heat insulating effect for the plurality of individual battery clusters 20.

[0055] Compared with the prior art, the present invention has at least the following advantages:

[0056] 1) Since the fireproof box is an inorganic high temperature resistant fireproof box 100; especially when used with an inorganic high temperature resistant fireproof partition 300, since the structural strength of the inorganic high temperature resistant fireproof box 100 and the inorganic high temperature resistant fireproof partition 300 is significantly higher than that of the traditional fireproof and flame retardant rock wool layer, and will not expand, the inorganic high temperature resistant fireproof box 100 and the inorganic high temperature resistant fireproof partition 300 can still maintain a good structural shape during a fire, are not prone to expansion or even collapse, and effectively avoid the spread of flames to a larger area, thereby reducing greater losses.

[0057] 2) Since the metal skeleton 200 is arranged in the accommodating cavity 110 and is threadedly connected to the inorganic high temperature resistant fireproof box 100, the inorganic high temperature resistant fireproof box 100 and the metal skeleton 200 are detachably arranged. On the one hand, the added metal skeleton 200 can provide better support and fixation for the fireproof box, effectively avoiding the problem of collapse and deformation of the fireproof box during long-term use; on the one hand, it is convenient for the operator to disassemble and assemble the fireproof box, and the damaged fireproof box can be replaced separately, thereby reducing the maintenance cost; on the other hand, since a hollow area 210 is formed in the metal skeleton 200, it is ensured that the inorganic high temperature resistant fireproof box 100 can be more comprehensively exposed, so as to realize the rapid fireproof and heat-insulating performance of the battery cluster 20, and effectively avoid the volatilization of the fireproof and heat-insulating performance of the fireproof box being interfered with by the addition of the metal skeleton 200.

[0058] 3) Since the fireproof partition is an inorganic high temperature resistant fireproof partition 300, each of the inorganic high temperature resistant fireproof partitions 300 is sequentially spaced and clamped on the side wall of the accommodating cavity 110, and the accommodating cavity 110 is divided into a plurality of battery compartments 113; the inorganic high temperature resistant fireproof partition 300 and the fireproof box are detachably arranged, which is convenient for the operator to disassemble and assemble, and the operator can replace the damaged inorganic high temperature resistant fireproof partition 300 separately, further reducing the maintenance cost. In addition, the inorganic high temperature resistant fireproof partition 300 can provide more reliable support for the interior of the accommodating cavity 110, effectively avoiding the problem of collapse and deformation of the energy storage station 1 during long-term use or fire.

[0059] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
