Description

Technical Field

[0001] The present disclosure relates to the technical field of safety of battery swap stations, and in particular to a waterless, fireproof and explosion-proof warehouse and a battery swap station. Background Art

[0002] With the continuous development of new energy vehicles, battery swap stations have also become widely popular. Battery swap stations can usually provide charging and battery replacement services for new energy vehicles. When some new energy vehicle batteries fail during charging or storage at battery swap stations, the emergency needs to be handled quickly and safely.

[0003] At present, the faulty battery is generally quickly transferred to the battery exchange platform, and then manually sprayed with fire water to cool down and extinguish the fire, or transferred to the fire water pool for emergency disposal in the station for cooling and extinguishing the fire. The method of manually spraying fire water requires a large amount of fire water and has high requirements for operators; the fire extinguishing method of immersion in the fire water pool has many problems such as water quality deterioration, evaporation and moisture, difficulty in adding water, insufficient water, and the need for regular maintenance.

[0004] Therefore, in order to find a new type of fireproof isolation technology, some scholars believe that the explosion-proof battery compartment on the market can be used in the faulty batteries of the battery swap station. For example, Chinese patent document No. CN117766925A discloses an explosion-proof battery compartment, and Chinese patent document No. CN114520393A discloses a lithium battery fireproof and explosion-proof isolation compartment.

[0005] However, in actual applications, since the body of an explosion-proof battery compartment is usually a metal compartment or a plastic compartment, when the faulty battery is quickly transferred to a traditional explosion-proof battery compartment, the faulty battery falls directly from a higher battery exchange platform, causing the faulty battery to be subjected to a greater impact during the falling process and suffer greater damage or violent combustion and explosion, that is, there is a major safety hazard. Utility Model Content

[0006] The purpose of the present disclosure is to overcome the shortcomings of the prior art and provide a waterless, fireproof and explosion-proof warehouse and battery swap station that avoids the phenomenon that a faulty battery is subjected to a greater impact during the falling process and thus suffers greater damage or violent combustion and explosion; and the water-free method reduces the daily maintenance cost of the battery swap station; and improves the recycling rate of the fireproof cover or explosion-proof cabin, thereby reducing the use cost.

[0007] The purpose of this disclosure is achieved through the following technical solutions:

[0008] A waterless fireproof and explosion-proof warehouse comprises an explosion-proof cabin body and a fireproof cover plate, wherein a cavity is formed in the explosion-proof cabin body, and the cavity has an opening.

[0013] In one embodiment, the organic fire retardant coating assembly includes a first organic fire retardant sublayer and a second organic fire retardant sublayer; the first organic fire retardant sublayer is arranged between the fireproof shock-absorbing pad and the bottom of the cavity; the second organic fire retardant sublayer is arranged between the flexible fireproof member and the side wall of the cavity; and / or,

[0014] The organic fire retardant coating component is a polyurea fire retardant coating component.

[0015] In one of the embodiments, the fireproof cover plate is a flexible fireproof cover plate, and the flexible fireproof cover plate includes a cover plate bracket and a flexible fire blanket connected to each other, and the cover plate bracket is provided with a clamping block, and the clamping block is clamped in the cavity.

[0016] In one embodiment, the flexible fire blanket includes a first fireproof silicone cloth layer, a fireproof expansion layer, an aramid interlayer, a ceramic fiber layer and a second fireproof silicone cloth layer which are stacked in sequence.

[0017] In one of the embodiments, the waterless fireproof and explosion-proof warehouse further includes a pressure relief component, which includes a pressure relief valve and a pressure relief pipe; the cavity also forms a pressure relief port, the pressure relief pipe is connected to the pressure relief port, and the pressure relief valve is arranged on the pressure relief pipe.

[0032] 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.

[0033] 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:

[0034] like Figures 1 to 3As shown, a waterless fireproof and explosion-proof warehouse 10 of an embodiment includes an explosion-proof cabin 100 and a fireproof cover 200, wherein a cavity 110 is formed in the explosion-proof cabin 100, and the cavity 110 has an opening, so that a faulty battery can fall into the cavity 110 from the opening; the fireproof cover 200 and the explosion-proof cabin 100 are detachably arranged, and the fireproof cover 200 is used to seal the opening; the waterless fireproof and explosion-proof warehouse 10 also includes a fireproof buffer assembly 300, and the fireproof buffer assembly 300 includes a fireproof shock-absorbing pad 310 and a flexible fireproof member 320, the fireproof shock-absorbing pad 310 is arranged at the bottom of the cavity 110, and the flexible fireproof member 320 is arranged on the side wall of the cavity 110.

[0035] It can be understood that since the fireproof buffer assembly 300 includes a fireproof shock-absorbing pad 310 and a flexible fireproof member 320, the fireproof shock-absorbing pad 310 is arranged at the bottom of the cavity 110, and the flexible fireproof member 320 is arranged at the side wall of the cavity 110, so that the bottom and side walls of the cavity 110 have certain buffering performance, when the faulty battery falls from a higher battery exchange platform into a traditional explosion-proof battery compartment, the fireproof shock-absorbing pad 310 and the flexible fireproof member 320 can provide a better buffer for the faulty battery, effectively avoiding the faulty battery from being further damaged or violently burning and exploding due to a greater impact during the falling process, thereby improving the safety of handling faulty batteries and reducing the probability of faulty batteries exploding. In addition, water-free reduces the daily maintenance cost of the battery exchange station.

[0036] Furthermore, since the fireproof cover 200 and the explosion-proof cabin 100 are detachably arranged, a separate design of the explosion-proof cabin 100 and the fireproof cover 200 is achieved, which is convenient for receiving faulty batteries on the one hand, and convenient for the operator to replace the damaged fireproof cover 200 or explosion-proof cabin 100 separately on the other hand, thereby improving the recycling rate of the fireproof cover 200 or explosion-proof cabin 100 and reducing the cost of use.

[0037] In this embodiment, the material formulas of the fireproof shock absorbing pad 310 and the flexible fireproof member 320 are both prior art and are not within the scope of protection of the application. Therefore, the present disclosure only protects the connection relationship and position relationship between the fireproof shock absorbing pad 310, the flexible fireproof member 320 and the cavity 110.

[0038] In one embodiment, the flexible fireproof component 320 includes a first flexible fireproof sub-component 321, a second flexible fireproof sub-component, a third flexible fireproof sub-component and a fourth flexible fireproof sub-component connected in sequence, wherein the first flexible fireproof sub-component 321 is arranged on the first side wall of the cavity 110; the second flexible fireproof sub-component is arranged on the second side wall of the cavity 110; the third flexible fireproof sub-component is arranged on the third side wall of the cavity 110; and the fourth flexible fireproof sub-component is arranged on the fourth side wall of the cavity 110, so as to ensure that the flexible fireproof components 320 are arranged on all four side walls of the cavity 110, especially in conjunction with the use of the fireproof shock-absorbing pad 310, so as to ensure that the faulty battery falling at 360 degrees will not produce a large impact, thereby better reducing the probability of the faulty battery exploding.

[0039] like Figure 2 and Figure 3 As shown, in one embodiment, the waterless fireproof and explosion-proof warehouse 10 further includes an organic fireproof coating component 400, and the organic fireproof coating component 400 is arranged between the explosion-proof cabin 100 and the fireproof buffer component 300, further improving the explosion-proof performance of the waterless fireproof and explosion-proof warehouse 10.

[0040] Specifically, in one embodiment, the organic fire retardant coating assembly 400 includes a first organic fire retardant sublayer 410 and a second organic fire retardant sublayer 420; the first organic fire retardant sublayer 410 is arranged between the fireproof shock absorbing pad 310 and the bottom of the cavity 110; the second organic fire retardant sublayer 420 is arranged between the flexible fireproof component 320 and the side wall of the cavity 110; the added first organic fire retardant sublayer 410 and the second organic fire retardant sublayer 420 can more comprehensively improve the explosion-proof performance of the waterless fireproof and explosion-proof warehouse 10, thereby better reducing the probability of explosion of faulty batteries.

[0041] In one embodiment, the organic fire retardant coating component 400 is a polyurea fire retardant coating component. Since the polyurea fire retardant coating component has good elasticity and explosion-proof performance, the added organic fire retardant coating component 400 can better ensure the explosion-proof performance of the waterless fire and explosion proof warehouse 10. Of course, those skilled in the art can also select other organic fire retardant coating components 400 of similar materials, such as polyurethane fire retardant coating components.

[0042] In one embodiment, the fireproof cover plate 200 is a flexible fireproof cover plate 200, and the flexible fireproof cover plate 200 includes a cover plate bracket 210 and a flexible fire blanket 220 connected to each other. The cover plate bracket 210 can provide good support for the flexible fire blanket 220, and the cover plate bracket 210 is provided with a card block, and the card block is arranged in the cavity 110, so as to realize the card arrangement of the cover plate bracket 210 and the cavity 110, and facilitate the operator to disassemble and assemble the cover plate. In addition, the flexible fire blanket 220 can reduce the collision and friction between the waterless fireproof and explosion-proof warehouse 10 and the faulty battery during transportation, thereby ensuring that the flexible fire blanket 220 can provide a good buffer for the faulty battery, further reducing the probability of the faulty battery exploding, and at the same time, the flexible fire blanket 220 can also well ensure that the flexible cover plate has a high fireproof and explosion-proof performance.

[0043] Specifically, Figure 4 As shown, in one embodiment, the flexible fire blanket 220 includes a first fireproof silicon cloth layer 221, a fireproof expansion layer 222, an aramid interlayer 223, a ceramic fiber layer 224 and a second fireproof silicon cloth layer 225 which are stacked in sequence, so as to ensure that the flexible fire blanket 220 has good softness and good fireproof and explosion-proof performance. It should be noted that the material formulas of the first fireproof silicon cloth layer 221, the fireproof expansion layer 222, the aramid interlayer 223, the ceramic fiber layer 224 and the second fireproof silicon cloth layer 225 are all prior art and are not within the scope of protection of this disclosure. This disclosure only protects the connection relationship and positional relationship between the first fireproof silicon cloth layer 221, the fireproof expansion layer 222, the aramid interlayer 223, the ceramic fiber layer 224 and the second fireproof silicon cloth layer 225.

[0044] like Figure 3 and Figure 4 As shown, in one embodiment, the waterless fireproof and explosion-proof warehouse 10 also includes a pressure relief component 500, and the pressure relief component 500 includes a pressure relief valve 510 and a pressure relief pipe 520; the cavity 110 is also formed with a pressure relief port, and the pressure relief pipe 520 is connected to the pressure relief port, and the pressure relief valve 510 is arranged on the pressure relief pipe 520. The additional pressure relief valve 510 can discharge the higher air pressure in the cavity 110, thereby ensuring that the air pressure in the cavity 110 reaches the set value, effectively avoiding the problem of explosion in the cavity 110 due to the high air pressure.

[0045] In one of the embodiments, the explosion-proof cabin 100 is a carbon steel composite explosion-proof cabin 100, so that the explosion-proof cabin 100 can provide strong structural support for the faulty battery, thereby ensuring that the explosion-proof cabin 100 is not prone to rupture when receiving a fallen faulty battery.

[0046] In one embodiment, the waterless fireproof explosion-proof warehouse 10 further includes universal wheels 600, which are arranged at the bottom of the explosion-proof cabin 100. The additional universal wheels 600 facilitate movement by the operator, effectively saving manpower.

[0047] The present disclosure also provides a battery swap station, including the waterless fireproof and explosion-proof warehouse 10 described in any of the above embodiments. The battery swap station includes a battery swap platform, which is used for faulty batteries. The waterless fireproof and explosion-proof warehouse 10 is located below the battery swap platform, so that the waterless fireproof and explosion-proof warehouse 10 can receive the faulty batteries. Since the fireproof shock-absorbing pad 310 and the flexible fireproof member 320 are added to the waterless fireproof and explosion-proof warehouse 10, the faulty batteries are effectively prevented from being damaged more severely or violently burning and exploding due to the greater impact during the falling process, thereby improving the safety of handling the faulty batteries.

[0048] In one of the embodiments, the battery swap platform includes a lifting component, and the battery swap platform realizes the lifting function through the lifting component.

[0049] Compared with the prior art, the present invention has at least the following advantages:

[0050] 1) Since the fireproof buffer assembly 300 includes a fireproof shock-absorbing pad 310 and a flexible fireproof member 320, the fireproof shock-absorbing pad 310 is arranged at the bottom of the cavity 110, and the flexible fireproof member 320 is arranged at the side wall of the cavity 110, so that the bottom and side walls of the cavity 110 have certain buffering properties, when the faulty battery falls from a higher battery exchange platform into a traditional explosion-proof battery compartment, the fireproof shock-absorbing pad 310 and the flexible fireproof member 320 can provide a better buffer for the faulty battery, effectively avoiding the faulty battery from being further damaged or violently burning and exploding due to a greater impact during the falling process, thereby improving the safety of handling faulty batteries and reducing the probability of faulty batteries exploding. In addition, water-free reduces the daily maintenance costs of battery exchange stations.

[0051] 2) Since the fireproof cover 200 and the explosion-proof cabin 100 are detachably arranged, a separate design of the explosion-proof cabin 100 and the fireproof cover 200 is realized. On the one hand, it is convenient to receive a faulty battery, and on the other hand, it is convenient for the operator to replace the damaged fireproof cover 200 or explosion-proof cabin 100 separately, thereby improving the recycling rate of the fireproof cover 200 or explosion-proof cabin 100 and reducing the cost of use.

[0052] 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.
