Description

Technical Field

[0002] The energy storage device includes a battery rack, a shell and a plurality of batteries. The battery rack is placed in the shell, and a plurality of battery compartments are formed on the battery rack, and each battery is arranged in a one-to-one correspondence with each battery compartment, so as to assemble an energy storage device with high energy density.

[0003] Since the batteries of the energy storage device are prone to thermal runaway during the charging and discharging process, and even explosion in severe cases, a fireproof partition is generally provided in the energy storage device, as disclosed in Chinese patent document No. CN 108417743B, which discloses a battery rack module and a battery rack module thereof, to improve the fireproof performance of the battery rack module.

[0004] However, from the above battery rack module Figure 1 and Figure 4 It can be seen that, since a semi-enclosed protective cover is formed on the top of the battery rack, the fireproof cover on the top can effectively prevent the flame and smoke from directly spreading to the four sides of the battery compartment, which is conducive to the concentrated discharge of flame and smoke from the energy storage device. However, when multiple batteries under the battery rack are burning at the same time, the flame and smoke that directly rush to the top of the battery rack are large, causing the top cover of the battery rack to be subjected to greater stress and easily loosen or even fall off, causing the flame to rush out of the adjacent battery compartment and cause greater losses.

[0032] 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.

[0033] 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.

[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 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.

[0035] 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:

[0036] like Figures 1 to 3As shown, a fireproof battery rack 100 of an embodiment includes a frame 110, a fireproof cover plate 120 and a plurality of fireproof baffles 130. The frame 110 is formed with a plurality of battery compartments 111, so that each battery compartment 111 can hold a corresponding energy storage battery 200; each of the fireproof baffles 130 is arranged between two adjacent battery compartments 111 to effectively block the transfer of flames and smoke between adjacent battery compartments 111, thereby reducing the area of ​​fire; please refer to Figures 4 to 5 The fireproof battery rack 100 also includes a plurality of fireproof elastic sealing rings 140 and a plurality of locking members 150; an installation cavity 121 is formed in the fireproof cover plate 120, an outlet 1211 is formed on one side of the installation cavity 121, and the top of the frame 110 is located in the installation cavity 121; each of the fireproof elastic sealing rings 140 is spaced and clamped on a surface of the fireproof cover plate 120 facing the frame 110; each of the locking members 150 is used to lock and fix the fireproof cover plate 120 and the fireproof elastic sealing ring 140 on the frame 110.

[0037] It can be understood that since the fireproof elastic sealing rings 140 are arranged at intervals on the side of the fireproof cover plate 120 facing the frame 110, on the one hand, it is convenient for the operator to disassemble and assemble the fireproof elastic sealing rings 140, which is conducive to replacing damaged fireproof elastic sealing rings 140; on the other hand, when the fireproof cover plate 120 is covered on the top of the frame 110, the fireproof elastic sealing ring 140 can contact with the top of the frame 110, and when the fireproof cover plate 120 is locked and fixed by the locking member 150, the fireproof elastic sealing ring 140 can be better deformed under the action of external force, thereby The connection firmness between the fireproof cover plate 120 and the frame 110 is improved, and the loosening or falling off of the fireproof cover plate 120 due to large flames and smoke is effectively avoided, and the flame is better prevented from escaping to the adjacent battery compartment 111 and causing greater losses; and because the fireproof elastic sealing ring 140 itself has good fireproof performance, the fireproof elastic sealing ring 140 can effectively block the flame inside the battery compartment 111 from escaping to the mounting hole 122 of the fireproof cover plate 120, thereby reducing the probability of the flame inside the battery compartment 111 spreading to the outside.

[0038] Furthermore, since an installation cavity 121 is formed in the fireproof cover plate 120, and an outlet 1211 is formed on one side of the installation cavity 121, the outlet 1211 is still retained when the fireproof cover plate 120 is covered on the top of the frame 110. When used in conjunction with the smoke exhaust port of the energy storage device 10, it is beneficial for the flame and smoke to be discharged in a directional manner to one side, that is, the flame and smoke are diverted, and the problem of larger flames and smoke rushing to the top of the battery rack and causing the top sealing plate to be subjected to greater force and easily loosened is further avoided.

[0039] like Figure 4 and Figure 5As shown, in one embodiment, the fireproof elastic sealing ring 140 includes an embedded portion 141 and a deformed abutting portion 142 connected to each other, the embedded portion 141 is formed with a through hole 1411, which is convenient for the locking member 150 to pass through; the deformed abutting portion 142 is formed with an abutting deformation cavity 1421, the abutting deformation cavity 1421 is connected to the through hole 1411, and the through hole 1411 is adapted to the locking member 150, so that the fireproof elastic sealing ring 140 will deform under the action of external force, so that the abutting deformation cavity 1421 can be better adsorbed and fixed on the frame 110, and the firmness of the connection between the fireproof cover plate 120 and the frame 110 is better improved; and because the frame 110 A threaded hole is formed on the top, and mounting holes 122 are correspondingly formed on both sides of the fireproof cover plate 120. The embedded portion 141 is clamped in the mounting hole 122 to realize the clamping arrangement of the fireproof elastic sealing ring 140 and the fireproof cover plate 120. When the locking member 150 passes through the mounting hole 122, the through hole 1411 and the threaded hole in sequence, the locking member 150 can be screwed with the inner wall of the threaded hole, so that the locking member 150 can lock and fix the fireproof cover plate 120 and the fireproof elastic sealing ring 140 to the frame 110, and it is convenient for the operator to replace the damaged fireproof cover plate 120 or the fireproof elastic sealing ring 140 separately, thereby reducing the maintenance cost.

[0040] It is worth mentioning that the conventional top sealing plate and the frame 110 are generally connected by thread and there is still an installation gap, which easily causes flames or smoke to escape from the installation gap between the fireproof cover plate 120 and the frame 110. Therefore, the fireproof elastic sealing ring 140 added in the present disclosure can be well deformed under the external force of locking, so that the fireproof elastic sealing ring 140 fills and seals in the installation hole 122 of the fireproof cover plate 120, effectively reducing the probability of flames or smoke from the installation gap between the fireproof cover plate 120 and the frame 110, and at the same time improving the firmness of the connection between the fireproof cover plate 120 and the frame 110.

[0041] In one embodiment, the locking member 150 is a bolt, or a screw rod, to achieve threaded connection with the threaded hole of the frame 110 .

[0042] In one of the embodiments, the embedding portion 141 and the deformable abutting portion 142 are an integrally formed structure, which improves the firmness of the connection between the embedding portion 141 and the deformable abutting portion 142 , thereby increasing the service life of the fireproof elastic sealing ring 140 .

[0043] like Figure 5As shown, in one of the embodiments, the cross-sectional area of ​​the embedded portion 141 is smaller than the cross-sectional area of ​​the deformable abutment portion 142. In this way, it is convenient for the operator to quickly install the fireproof elastic sealing ring 140 in the mounting hole 122 corresponding to the fireproof cover plate 120, and the deformable abutment portion 142 with a larger cross-sectional area can be well limited and fixed in the mounting hole 122. On the one hand, the firmness of the connection between the fireproof elastic sealing ring 140 and the fireproof cover plate 120 is improved, and on the other hand, the contact area between the fireproof elastic sealing ring 140 and the frame 110 is increased. At the same time, with the use of the abutment deformation cavity 1421 of the fireproof elastic sealing ring 140, the fireproof elastic sealing ring 140 can be better adsorbed and fixed on the frame 110 under the action of external force, thereby improving the firmness of the connection between the fireproof elastic sealing ring 140 and the frame 110, so that the fireproof elastic sealing ring 140 can well bear the firmness of the connection between the fireproof elastic sealing ring 140 and the frame 110.

[0044] like Figure 2 As shown, in one embodiment, a preset gap 123 is formed between the inner wall of the installation cavity 121 and the top of the frame 110, and the preset gap 123 is connected to the outlet 1211, so that the added preset gap 123 can guide more flames and smoke, which is beneficial for the discharge of flames and smoke to the outlet 1211, and effectively avoids the problem that larger flames and smoke gather on the top of the battery rack, causing the top cover to be subjected to greater force and easy to loosen.

[0045] In one embodiment, the fireproof cover plate 120 includes a fireproof support plate 124, a first fireproof shielding member 125 and a second fireproof shielding member 126, wherein the first fireproof shielding member 125 is arranged on the first side periphery of the fireproof support plate 124, and the second fireproof shielding member 126 is arranged on the second side periphery of the fireproof support plate 124; and since the first side of the fireproof support plate 124 is arranged opposite to the second side of the fireproof support plate 124, the fireproof support plate 124, the first fireproof shielding member 125 and the second fireproof shielding member 126 are connected together to form the installation cavity 121, and the outlets 1211 are respectively formed on the third side of the fireproof support plate 124 and the fourth side of the fireproof support plate 124, so as to increase the number of outlets 1211, facilitate the discharge of flames and smoke to the outlets 1211, and better avoid the problem that larger flames and smoke gather on the top of the battery rack, causing the top sealing plate to be subjected to greater force and easily loosen.

[0046] like Figure 3As shown, in one of the embodiments, the first fireproof shielding member 125 is connected to the first side periphery of the fireproof support plate 124 to form a first avoidance groove 127; the first avoidance groove 127 can effectively block the flame and smoke from spreading to the middle of the fireproof support plate 124, so that more flame and smoke can be better discharged and circulated to the outlet 1211, effectively avoiding the problem that larger flame and smoke gather at the top of the battery rack and cause the top sealing plate to be subjected to greater force and easily loosen.

[0047] Likewise, if Figure 3 As shown, in one embodiment, the second fireproof shielding member 126 is connected to the second side periphery of the fireproof support plate 124 to form a second avoidance groove 128 to better achieve the diversion of more flames and smoke.

[0048] Each locking member 150 can be located at the four corners of the fireproof support plate 124, and of course, other distribution arrangements are also possible. For example, in one embodiment, a portion of the locking members 150 is distributed at both ends of the first fireproof shielding member 125, and another portion of the locking members 150 is distributed at both ends of the second fireproof shielding member 126, so that each locking member 150 can be located at the four corners of the fireproof cover plate 120 to ensure the firmness of the connection between the fireproof cover plate 120 and the frame.

[0049] When a part of the locking members 150 are distributed at both ends of the first fireproof shielding member 125 and another part of the locking members 150 are distributed at both ends of the second fireproof shielding member 126, the length of the deformed abutment portion 142 of the fireproof elastic sealing ring 140 is adapted to the preset gap 123, so that the deformed abutment portion 142 of the fireproof elastic sealing ring 140 can be well sealed and abutted against the frame 110.

[0050] In a preferred embodiment, the frame 110 is a metal frame so that the abutting deformation cavity 1421 of the deformable abutting portion 142 can be well fixed and adsorbed on the frame 110. Figure 3 As shown, in one embodiment, the fireproof battery rack 100 also includes a plurality of fireproof reinforcements 160, and each of the fireproof reinforcements 160 is arranged at intervals on the fireproof cover plate 120. The added fireproof reinforcements 160 can better improve the overall structural strength of the fireproof cover plate 120, and effectively prevent larger flames and smoke from gathering on the top of the battery rack, causing the top cover plate to be subjected to greater stress and easily become loose or damaged.

[0051] like Figure 3 As shown, in one embodiment, each of the fireproof reinforcement members 160 is equidistantly arranged along the length direction of the fireproof cover plate 120 to ensure that the added fireproof reinforcement members 160 can provide uniform supporting force for the fireproof cover plate 120, thereby ensuring that the overall force strength of the fireproof cover plate 120 is relatively stable.

[0052] like Figure 3 As shown, in one of the embodiments, a snap-in groove 161 is formed on one side of the fireproof reinforcement 160 facing the frame 110, and the snap-in groove 161 is used for snap-in connection with the frame 110, further improving the firmness of the connection between the fireproof reinforcement 160 and the frame 110, and effectively avoiding the problem that the fireproof cover panel 120 with a larger area is easily loosened and fallen off due to the lack of connection in the middle in large flames and smoke.

[0053] In one embodiment, the fireproof reinforcement member 160 is located at the connection between the first fireproof shielding member 125 and the fireproof support plate 124 to form a first clamping avoidance groove, and the fireproof reinforcement member 160 is located at the connection between the second fireproof shielding member 126 and the fireproof support plate 124 to form a second clamping avoidance groove. In this way, when the fireproof cover plate 120 is covered on the top of the fireproof battery rack 100, the added fireproof reinforcement member 160 will not interfere with the fireproof cover plate 120, so that the fireproof cover plate 120 can be flatly attached to the top of the fireproof battery rack 100, so as to ensure that more flames and smoke can be quickly discharged to the outlets 1211 on both sides of the fireproof cover plate 120.

[0054] like Figure 1 to Figure 2 As shown, the present disclosure also provides an energy storage device 10, including an energy storage battery 200 and a fireproof battery rack 100. In one embodiment, the energy storage device 10 also includes a shell (not shown), each energy storage battery 200 is correspondingly arranged in the battery compartment 111, and the shell is provided with a smoke exhaust port corresponding to the outlet 1211 of the fireproof cover plate 120, and the fireproof battery rack 100 is located in the shell, so that when the fireproof cover plate 120 is covered on the top of the fireproof battery rack 100, the outlet 1211 is still left, which is conducive to the directional discharge of flames and smoke to the smoke exhaust port, so as to avoid the problem that larger flames and smoke rush to the top of the battery rack and cause the top sealing plate to be subjected to greater force and easy to loosen.

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

[0056] 1) Since the fireproof elastic sealing rings 140 are arranged at intervals on the side of the fireproof cover plate 120 facing the frame 110, on the one hand, it is convenient for the operator to disassemble and assemble the fireproof elastic sealing rings 140, which is conducive to replacing damaged fireproof elastic sealing rings 140; on the other hand, when the fireproof cover plate 120 is covered on the top of the frame 110, the fireproof elastic sealing ring 140 can contact with the top of the frame 110, and when the fireproof cover plate 120 is locked and fixed by the locking member 150, the fireproof elastic sealing ring 140 can be better deformed under the action of external force, thereby improving the fireproof elastic sealing ring 140. The connection firmness between the fireproof cover plate 120 and the frame 110 is improved, and the loosening or falling off of the fireproof cover plate 120 due to large flames and smoke is effectively avoided, and the flame is better prevented from escaping to the adjacent battery compartment 111 and causing greater losses; and because the fireproof elastic sealing ring 140 itself has good fireproof performance, the fireproof elastic sealing ring 140 can effectively block the flame inside the battery compartment 111 from escaping to the mounting hole 122 of the fireproof cover plate 120, thereby reducing the probability of the flame inside the battery compartment 111 spreading to the outside.

[0057] 2) Since an installation cavity 121 is formed in the fireproof cover plate 120, and an outlet 1211 is formed on one side of the installation cavity 121, the outlet 1211 is still retained when the fireproof cover plate 120 is covered on the top of the frame 110. When used in conjunction with the smoke exhaust port of the energy storage device 10, it is beneficial for the flame and smoke to be discharged to one side in a directional manner, that is, the flame and smoke are diverted, and the problem of larger flames and smoke rushing to the top of the battery rack and causing the top sealing plate to be subjected to greater force and easily loosened is further avoided.

[0058] 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.
