Description

Battery storage cabinet and dry room for storing the cabinet

[0001] The present invention relates to a battery storage cabinet and a dry room capable of storing the cabinet, and more specifically, to a battery storage cabinet capable of individually storing a plurality of used batteries, thereby enabling individual extinguishing in the event of a fire, thereby preventing the spread of fire, reducing the emission of harmful gases, and preventing secondary damage due to an explosion through a double storage structure, and a dry room capable of storing the cabinet.

[0002] As the global push for carbon neutrality continues, the spread of electric vehicles is expanding to reduce carbon emissions. However, the spread of electric vehicles inevitably leads to the generation of batteries after use.

[0003] The core of electric vehicles is the high-voltage battery, but the battery cannot be used permanently due to aging (deterioration) caused by use.

[0004] In the case of batteries, when their lifespan falls below a certain level, they are separated and reused or recycled during the scrapping process of electric vehicles.

[0005] The average lifespan of electric vehicle batteries is 7 to 10 years. In Korea, batteries began to be discharged in 2017, and according to data from the Ministry of Environment, the cumulative number of batteries used in electric vehicles is expected to be around 100,000 by 2030.

[0006] In the case of batteries used in electric vehicles (subsidy eligible), they are returned to the four 'Future Waste Collection Centers' managed by the Korea Environment Corporation on land and to the 'Electric Vehicle Battery Industrialization Center' managed by Jeju Technopark on Jeju Island, as stipulated in the Clean Air Conservation Act. However, due to the lack of reuse and recycling technology, they are simply stored in warehouses.

[0007] These batteries are potentially explosive and dangerous materials, making it difficult to extinguish fires due to thermal runaway in the event of a fire. Fires can occur for various reasons during use, transportation, and storage. While it is impossible to prevent fires, it is possible to prevent secondary damage by extinguishing fires.

[0059] The terms used in the present invention are selected from the most widely used general terms as much as possible, but in certain cases, there are terms arbitrarily selected by the applicant. In such cases, the meaning of the terms should be understood by considering the meaning described or used in the detailed description of the invention, rather than the simple name of the term.

[0060] Hereinafter, the technical configuration of the present invention will be described in detail with reference to preferred embodiments illustrated in the attached drawings.

[0061] However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Like reference numbers designate like elements throughout the specification.

[0062]

[0063] FIG. 1 is a drawing showing a battery storage cabinet according to one embodiment of the present invention, FIG. 2 is a drawing showing a state in which a battery is stored in a battery storage cabinet according to one embodiment of the present invention, and FIG. 3 is a drawing looking at the rear of a battery storage cabinet according to one embodiment of the present invention.

[0064] Referring to FIGS. 1 to 3, a battery storage cabinet (100) according to one embodiment of the present invention comprises a cabinet body (110) and a door (120).

[0065] The above cabinet body (110) is a body having a plurality of battery storage rooms (111) that are partitioned vertically from each other.

[0066] In addition, the battery storage compartment (111) is opened forward and a battery (10) can be inserted and stored.

[0067] That is, the battery storage cabinet (100) according to one embodiment of the present invention is a cabinet that can individually store different batteries (10) in different spaces rather than in one space.

[0068] Therefore, even if a fire breaks out in one battery, it can prevent the fire from spreading to other batteries, and firefighting water can be supplied only to that space to extinguish the fire individually.

[0069] In addition, the battery (10) is placed on a pallet (20) and transported by a forklift to be placed in the battery storage room (111). However, if the battery is placed without considering the entry direction or entry limit of the pallet (20), the inner wall of the battery storage room (111) may be damaged or the battery (10) may be damaged.

[0070] Therefore, in the present invention, an elongated guideline (112) is formed in the entry direction on the bottom surface of the battery storage room (111) so that the pallet (20) is guided by making contact with the guideline (112), thereby allowing it to be inserted in the correct entry path and direction.

[0071] In addition, when the above pallet (20) is pushed in deeply, the tip of the above guideline (112) is caught on the inner jaw of the pallet (20), preventing further entry, thereby providing an entry limit.

[0072] That is, according to the present invention, the battery (10) can be safely loaded through the above guideline (112).

[0073] The above door (120) is hinged at the open front of each battery storage compartment (111) so that the battery storage compartment (111) can be opened and closed.

[0074] Additionally, the door (120) includes a left door (121) hinged at the left corner of the entrance to the battery storage room (111) and a right door (122) hinged at the right corner of the entrance.

[0075] That is, the above door (120) is a door that can be opened and closed from both sides.

[0076] In addition, an elastic seal (not shown) for watertightness may be attached to the part where the door (120) and the cabinet body (110) come into contact to prevent fire water supplied to the inside from being discharged in the event of a fire.

[0077] In addition, referring to FIG. 4, when the doors (121, 122) of the left door (121) among the doors (120) are closed, an extended extension surface (121b) is formed at the rear edge of the interlocking side surface (121a), and the side rear edge of the right door (122) closes by pressing the extended surface, so that the inside of the battery storage room (111) is sealed without being exposed as much as possible by the extended surface (121b).

[0078] However, the above extension surface (121b) may be provided on the right door (122).

[0079] In addition, a frame exists on the front of the cabinet body (110) to partition between each of the battery storage rooms (111), and a clamp is provided on the frame to press the front of the door (120) to seal the battery storage room (111).

[0080] Referring to FIG. 5 in detail, FIG. 5 shows the clamp (130), which comprises a screw rod (131) having one end fastened to the frame (111a), a screw thread formed on the outer surface, and rotatable while maintaining a fixed position, a press bar (132) having a central portion penetrated by the screw rod (131) and capable of moving forward or backward when the screw rod (131) rotates, and moving forward to press the front of the upper door and the lower door so that the doors (120) can close and seal the battery storage compartment (111), and a handle (133) connected to the other end of the screw rod (131) and capable of being held by a user to rotate the screw rod (131).

[0081] Additionally, the pressure bar (132) may be provided with an elastic resin block such as rubber at the part that comes into contact with the doors (120).

[0082] In addition, referring to FIG. 3, a ventilation hole is perforated on the upper side of the inner surface of each battery storage room (111) to discharge gas and pressure to the outside in the event of a fire, and a ventilation pipe (140) protruding laterally is provided on the outer surface of the cabinet body (110) so as to be connected to the ventilation hole and discharge gas and pressure to the outside.

[0083] In addition, it is preferable that the ventilation pipe (140) be bent upwards so that the gas and pressure are discharged upwards. This is to prevent the gas or pressure from being sprayed onto people passing by.

[0084] In addition, referring to Fig. 6, a filter (142) is provided at the inlet (141) of the ventilation hole to prevent foreign substances contained in the fire water supplied to the battery storage room (111) from being discharged through the ventilation hole. Accordingly, environmental pollution in the surrounding area can be reduced during fire fighting.

[0085] In addition, in Fig. 3, the ventilation pipe (140) is shown as being installed on the rear of the cabinet body (110), but it can also be installed on the side.

[0086] In addition, the outer surface of the cabinet body (110) is provided with a water supply port (150) that can supply fire water through the interior of each battery storage room (111) and a drain port (160) that can drain the fire water supplied to the interior, and the height of the water supply port (150) is positioned at a relatively higher position than the height of the drain port (160).

[0087] That is, there is an advantage in that fire water is supplied to each battery storage room (111) so that individual fire extinguishing is possible in the event of a fire.

[0088] In addition, referring to FIG. 7, a rotation plate (152) is hinged and rotates at the outlet of the water supply port (150), and a damper (151) is provided to open the outlet of the water supply port (150) when water is supplied, and close the water supply port when water is not supplied.

[0089] In addition, a filter (161) is provided at the inlet of the drain (160) to prevent foreign substances contained in the supplied fire water from being discharged into the drain (160).

[0090] Therefore, it is possible to prevent the surrounding environment from being polluted during digestion as much as possible.

[0091] Meanwhile, each side of the cabinet body (110) is insulated with a triple structure, and is composed of a steel outer surface (114), a steel inner surface (113), and ceramic fiber (115) filled between the steel outer surface (114) and the steel inner surface (113).

[0092] Additionally, the ceramic fiber (115) may use KCC's Cerakwool.

[0093] Therefore, according to the battery storage cabinet (100) of the present invention, there is an advantage in that each battery (10) can be stored separately after use, and can be individually extinguished in the event of a fire.

[0094] In addition, the present invention further provides a dry room for a battery storage cabinet capable of storing the battery storage cabinet (100) itself.

[0095] Fig. 8 shows a dry room (200) for the battery storage cabinet. The dry room (200) for the battery storage cabinet is a body having a space inside, and the battery storage cabinet (100) can be stored in the space inside.

[0096] That is, the battery (10) after use can be stored in a double storage structure through the battery storage cabinet (100) and the dry room (200) for the battery storage cabinet.

[0097] This is a structure that can prevent secondary damage in the event of a battery explosion or other situation in the event of a fire.

[0098] Additionally, the dry room (200) for the battery storage cabinet is equipped with a scrubber that can filter out internal harmful gases and discharge them to the outside in the event of a fire.

[0099] In addition, FIG. 10 shows the scrubber (210), which includes a fan (211) that sucks in internal harmful gases, a filter box (212) that filters out harmful substances in the harmful gases sucked in by the fan (211), and an exhaust port (123) that discharges purified air that has passed through the filter box (212) to the outside.

[0100] In addition, the filter box (212) is sequentially equipped with a HEPA filter (212a), a vinyl chloride filter (212b), and a HEPA filter (212c) to purify harmful gases in a triple structure.

[0101] In addition, referring to FIG. 9, the side of the dry room (200) for the battery storage cabinet is provided with an external water supply port (220) that penetrates the side and is connected to the water supply port (150) of the battery storage cabinet (100), and an external drain port (230) that penetrates the side and is connected to the drain port (160) of the battery storage cabinet (100).

[0102] In addition, the external water supply ports (220) are each connected to one external water supply line (240) through a ball valve (241), and the external drain ports (230) are each connected to one drain line (250) through a ball valve (251).

[0103] That is, in the event of a fire, fire water can be supplied to the external water supply line (240) and the ball valve (241) connected to the battery storage room (111) where the fire occurred can be opened to supply water.

[0104] This is to enable firefighters to extinguish a fire by connecting a fire water supply pipe to an external water supply line (240) and opening a ball valve (241) without having to identify a water supply location in an emergency situation.

[0105] In addition, since fire water can be discharged to a specific location and height through one external drainage line (250), there is an advantage in that it is easy to collect fire water, which is waste.

[0106]
