Detailed Implementation

[0020] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] See Figure 1 and Figure 2 As shown, the battery safety storage and transportation box of this utility model includes components such as box body 1, self-fusing separator assembly 2, and cover 3.

[0022] The enclosure includes a shell 11 welded from sheet metal, a base 12 located at the bottom of the shell 11, and a PP inner liner 13 located inside the shell 11. See also Figure 4 As shown, the outer shell 11 is made of sheet metal. The entire shell is a cuboid structure, with columns 14 set at the four corners of the outer shell 11. Fireproof boards 15 are laid flat between the columns 14, and a PP inner liner 13 is then placed inside the outer shell 11. The PP inner liner 13 limits and fixes the fireproof boards 15, sandwiching them in the interlayer to form a fireproof partition.

[0023] See Figure 5 As shown, a water outlet ball valve 121 is provided on the base 12. The water outlet ball valve 121 is connected to the drain hole at the bottom of the PP inner liner and the box body, allowing for water replacement. Furthermore, a support foot 122 is provided on the lower surface of the base 12, which elevates the entire box body for easy transport by forklifts, etc. Casters 123 are provided on the base 12 for easy pushing. The height of the casters 123 is slightly higher than the support feet, but this does not affect stacking. When a single box body is placed on the ground, it is placed on the ground and moved by the casters 123. If movement is not required, the casters can be removed, and the support feet 122 can be used for grounding. The base 12 also has multiple reinforcing ribs 124 to enhance the overall load-bearing capacity.

[0024] The self-fusing partition assembly 2 is disposed within the PP inner liner 13 and connected to the fireproof plate and the outer shell via fasteners, forming a double fixation. The self-fusing partition assembly 2 divides the space within the PP inner liner 13 into an upper storage space 131 and a lower water storage space 132, such as... Figure 10 As shown. Please see below. Figure 9As shown, the self-fusing separator assembly 2 includes a mesh separator 21 and four fusible metal support plates. Each fusible metal support plate comprises an upper support plate 221 and a lower support plate 222 formed by welding fusible metal together, with fusible metal filling the space between the upper and lower support plates. When the temperature reaches the melting point, the upper support plate 221 and the lower support plate 222 will detach, and the stored battery will fall into the lower water storage space 132 to extinguish the fire. The self-fusing separator assembly 2 and the PP inner liner 13 are edge-sealed by applying adhesive, and the mesh of the mesh separator 21 is waterproofed by covering the mesh with a PE film.

[0025] like Figure 2 As shown, the cover 3 is connected to the upper surface of the box body 1 via a hinge 4. Furthermore, the cover 3 and the box body 1 are secured together by a fastener 5. Figure 6 As shown, the cover 3 includes a top cover plate 31, a top cover sealing plate 32, and a top cover fireproof plate 33. The top cover sealing plate 32 is disposed between the top cover plate 31 and the top cover fireproof plate 33. The cover 3 is provided with an explosion relief device 34 and a purification module 35. The purification module 35 is correspondingly disposed at the outlet (i.e., pressure relief hole) of the explosion relief device 34.

[0026] See Figure 8 As shown, the explosion relief device 34 includes an explosion relief enclosure 341, an explosion relief cover 342, a screw 343, a pressure spring 344, and a locking nut 345. A pressure relief hole is provided on the cover 3. The explosion relief enclosure 341 is fixed to the outside of the pressure relief hole, and the screw 343 is fixed to the inner wall of the explosion relief enclosure 341. The pressure spring 344 is sleeved on the screw 343 and is limited and adjusted by the locking nut 345. The explosion relief cover 342 is pressed onto the pressure relief hole by the pressure spring 344 to seal the pressure relief hole. The explosion relief enclosure 341 is welded to the cover 3 and guides the internal pressurized gas upwards for discharge; the remaining components together form the pressure relief assembly. When the pressure rises and exceeds the pre-set spring pressure value of the pressure spring 344, it will push the explosion vent cover 342 upward to relieve pressure. Lifting it upward will further compress the pressure spring 344, increasing the spring pressure value. After the pressure is released, the pressure spring 344 will press the explosion vent cover 342 downward to achieve a seal. The screw 343 and locking nut 345 act as the central axis of the spring's movement and provide fixation. Simultaneously, the locking nut can adjust the pressure of the pressure spring. (See also...) Figure 6 and Figure 7As shown, the purification module 35 includes a fixing frame 351 and an activated carbon pack 352. One side of the fixing frame 351 is hollowed out. The fixing frame 351 is fixed between the fireproof plate of the top cover and the sealing plate of the top cover and corresponds to the pressure relief hole. When an accidental combustion occurs inside, the pressure rises, and the generated toxic gases will be released from the explosion relief device 34. During the pressure relief process, the gases will first pass through the purification module 35 for gas filtration, thereby achieving toxicity purification, meeting air emission standards, and ensuring personnel safety.

[0027] In addition, stacking lugs 71 are provided at the four corners of the upper end of the shell 11. Buffer rubber strips 72 are attached inside the stacking lugs 71. The stacking lugs 71 allow for the stacking of another storage / transportation box above them, such as... Figure 11 As shown. Furthermore, a limiting pin 73 is provided on the stacking lug, and a locking block 36 is provided on the side of the cover 3 where the hinge is located. The limiting pin 73 is inserted into the hole on the locking block 36 to enhance the stability of the upper box, preventing the two boxes from falling off due to strong vibrations during transportation. A limiting wing screw 9 is also provided on the stacking lug 71.

[0028] like Figure 3 As shown, a fireproof expansion strip 8 is provided at the junction of the box body and the cover body. The fireproof expansion strip expands when heated and fills the gap between the box body and the cover body, thereby enhancing the isolation effect between the inside and outside flames.

[0029] The PP inner liner 13 is made of PP board, which can effectively prevent corrosion and prevent damage caused by corrosion when battery electrolyte is accidentally leaked.

[0030] In summary, this invention is fireproof, explosion-proof, and corrosion-resistant. It is also easy to transport and stack.

[0031] The embodiments described above are for illustrative purposes only and are not intended to limit the scope of this utility model. All equivalent changes and modifications made to this utility model by those skilled in the art should fall within the scope of the appended claims.
