When the electric push rod 6 is extended to the extreme position, the upper end of the battery storage unit 4 is immersed in the water cooling box 2, and the water in the water cooling box 2 is poured into the battery storage unit 4; an inlet pipe 7 connected to the electrical compartment 102 is arranged on the top of the cabinet 1, and a second machine cover 8 covering the inlet pipe 7 is installed on the top of the cabinet 1.

[0045] In the above technical solution, the water cooling box 2 is a double-layer structure with upper and lower layers, wherein the lower part is made of acrylic and the top plate is made of aluminum alloy plate. When in use, the water cooling box 2 is filled with cooling water, and the cooling water is circulated in and out, and a circulating water pump is used for water circulation. The circulated water is cooled by an external cooling device and reused. The battery is stored in the battery storage unit 4, and each battery storage unit 4 is an independent structure, and the battery storage unit 4 is wrapped with cooling water. The battery storage unit 4 is always in a relatively low temperature state, preferably 20 to 25 degrees Celsius.

[0046] The electric push rods 6 are independently powered by the mains, and each electric push rod 6 is equipped with an independent control switch, which is installed on the outside of the cabinet 1 or in the main control room. When a battery in a battery storage unit 4 has thermal runaway, the corresponding electric push rod 6 is controlled to make the battery storage unit 4 sink into the water cooling box 2, so as to achieve immersion-type fire extinguishing and cooling, and prevent the spread of fire.

[0047] It should be noted that the control switch connected to the control electric push rod 6 needs to be connected to the main switch of the energy storage cabinet. When the control switch is pressed, the main switch of the energy storage cabinet is cut off to avoid leakage when extinguishing the fire.

[0048] An independently designed overflow pipe is used to discharge excess water when the battery storage unit 4 sinks, thereby preventing water from overflowing onto the top of the water cooling box 2.

[0049] See also Figure 1 and Figure 3 As shown, a base frame 9 is installed at the bottom of the cabinet 1, and the base frame 9 is a frame. A ventilation groove 91 is processed on the outer side of the base frame 9, and ventilation holes 92 are drilled at the bottom of the cabinet 1 at the position corresponding to the base frame 9; a bottom beam 10 is arranged at the inner bottom of the battery compartment 103, and the ventilation holes 92 are distributed on both sides of the bottom beam 10, and the bottom of the water cooling box 2 is supported by the bottom beam 10.

[0050] In the above technical solution, the height of the bottom frame 9 is 10 cm. With the support of the bottom frame 9, the bottom of the cabinet 1 is lifted off the ground, keeping the bottom of the cabinet 1 dry and reducing corrosion.

[0051] The bottom beam 10 is used to support the water cooling box 2 , so that the bottom of the water cooling box 2 is suspended, which facilitates natural cooling of the water cooling box 2 through the ventilation holes 92 .

[0052] See also Figure 1 As shown, an observation slot 101 corresponding to the water cooling box 2 is opened at the front end of the cabinet 1, and the water cooling box 2 is made of acrylic material.

[0053] In the above technical solution, it is convenient to visually see the water level in the water cooling box 2 and the water circulation status.

[0054] See also Figure 5 As shown, a first partition 199 is provided on the side of the partition 101 facing the electrical compartment 102 , and heat insulation cotton 198 is filled between the first partition 199 and the partition 101 .

[0055] This technical solution mainly plays the role of temperature insulation.

[0056] See also Figure 2 and Figure 4 As shown, a partition plate 201 is provided on the top of the water cooling box 2, and the end of the partition plate 201 is connected with the groove wall of the battery compartment 103, and the partition plate 201 protrudes to the water collecting tank 3. The upper end of the partition plate 201 is against the first machine cover 5, and a wire hole 202 is drilled on the plate surface of the partition plate 201. The height of the wire hole 202 is higher than the height of the water collecting tank 3. A wire groove 501 is opened at the end surface where the first machine cover 5 contacts the second machine cover 8. The top of the water collecting tank 3 is divided into a plurality of independent slots 331 by the partition plate 201, and each of the battery storage units 4 occupies one of the slots 331; a drainage pipe 332 connected to the slots 331 is provided on the side of the cabinet 1.

[0057] In the above technical solution, a partition plate 201 is used for partitioning. When a battery in one of the battery storage units 4 burns violently, a flame will burst out. The partition plate 201 can prevent the bursting flame from directly burning the battery storage unit 4 next door.

[0058] The height of the wire hole 202 is higher than the height of the water collecting tank 3. When the burning battery storage unit 4 is sunk into the water cooling box 2, some water will overflow from the opening 299. The wire hole 202 designed in this way can prevent the overflowed water from entering the adjacent slot 331.

[0059] See also Figure 2 and Figure 4 As shown, a heat dissipation fan 333 corresponding to the slot 331 is arranged on the top of the first machine cover 5, and an inspection slot is arranged at the middle position of the first machine cover 5. A grid plate 334 is detachably installed in the inspection slot, and the grid plate 334 is connected to each of the slots 331.

[0060] In the above technical solution, the heat dissipation fan 333 can be used to achieve air cooling.

[0061] The operating temperature of the battery can be dissipated from the top of the battery storage unit 4, and heat can be discharged in conjunction with the cooling fan 333.

[0062] See also Figure 2 , Figure 6 and Figure 7 As shown, the battery storage unit 4 includes a heat-conducting battery box 401, a box cover 402 is detachably installed on the top of the battery box 401, and the box cover 402 and the battery box 401 are sealed with glue. A connecting pipe 403 is arranged on the top of the box cover 402, and a connecting rod 404 is arranged on the upper end of the connecting pipe 403. A wire outlet hole 405 is drilled on the upper end of the connecting pipe 403, and a through hole 406 is arranged on the outer wall of the connecting pipe 403 near the upper position. The outer wall of the connecting pipe 403 is located at the through hole 40 6 is provided with an annular groove 407, and a sealing member 408 is cooperated with the groove 407. The upper end of the connecting rod 404 is connected to the telescopic end of the electric push rod 6, and the connecting pipe 403 is matched with the opening 299. When the electric push rod 6 retracts, the connecting pipe 403 goes up along the opening 299. At this time, the sealing member 408 is squeezed with the inner top surface of the water cooling box 2 to form a seal, and the through hole 406 is exposed above the water cooling box 2; a heat exchange plate 489 is installed on the outer wall of the water cooling box 401.

[0063] In the above technical solution, the batteries are stored in the battery box 401, and the battery box 401 is made of aluminum or copper with good thermal conductivity. It should be noted that the wiring harness connecting the batteries needs to be effectively insulated to avoid leakage.

[0064] Through the sealing member 408, when the electric push rod 6 retracts, the sealing member 408 forms a seal on the bottom periphery of the opening 299 to prevent water penetration.

[0065] The heat exchange effect can be improved by using the heat exchange plate 489, and the temperature inside the battery box 401 can be further effectively reduced.

[0066] It should be noted that when the outdoor temperature is lower than 5 degrees, the water in the water cooling box 2 needs to be pumped out, and the coldness of the air is sufficient to complete the heat dissipation work. At this time, the water cooling box 2 plays a role in keeping the battery box 401 warm.

[0067] See also Figure 6 and Figure 8 As shown, a float box 441 is installed at the bottom of the battery box 401, the interior of the float box 441 is a sealed cavity, a groove 442 is arranged at the upper end of the float box 441, and a water-permeable groove 443 connected to the groove 442 is arranged on the outer side of the float box 441; when the electric push rod 6 is extended to the extreme position, the bottom of the float box 441 maintains a distance from the bottom of the water cooling box 2.

[0068] In the above technical solution, the buoyancy is provided by the float box 441. The battery box 401 itself has a certain buoyancy, and the buoyancy can be further increased by cooperating with the float box 441. When water is injected into the water cooling box 2, the float box 441 and the battery box 401 naturally float up, which can prevent the electric push rod 6 from being subjected to downward pulling force.

[0069] The design of the water-permeable groove 443 allows the bottom of the battery box 401 to be in normal contact with the cooling water.

[0070] See also Fig. 9 and Fig.10 As shown, insulating rails 444 are correspondingly provided at the inner side walls of the battery box 401 , and a battery clamp 445 is slidably fitted between the corresponding insulating rails 444 on both sides.

[0071] In the above technical solution, the insulating rail 444 is used in conjunction with the battery clamp 445 to prevent leakage from being transmitted to the battery box 401 even if the battery leaks.

[0072] See also Figure 7 and Fig.13 As shown, the sealing member 408 includes a main body 481 made of elastic rubber material, and more than two sealing rings 482 are injection-molded on the top of the main body 481. The main body 481 and the card slot 407 are interference fit, and the mating surfaces are glued and fixed by fixing glue, and the height of the more than two sealing rings 482 gradually increases toward the axial direction of the main body 481.

[0073] In the above technical solution, a sealing ring 482 with a variable height is used. When the electric push rod 6 retracts, the compression amplitudes of the inner and outer sealing rings 482 are different, and the inner sealing ring 482 is subjected to a greater extrusion pressure.

[0074] Through this special design, multiple layers of waterproofing can be formed below the opening 299 to avoid water leakage.

[0075] See also Fig.10 , Fig.11 and Fig.12As shown, the insulating rail 444 has a dovetail groove 4441, and the battery clamp 445 includes an upper and a lower clamping plate 4451. Rubber protrusions 4452 are embedded on the opposite surfaces of the two clamping plates 4451. Side ear plates 4453 are arranged on both sides of the clamping plates 4451. The side ear plates 4453 fit into the dovetail groove 4441 and slide vertically along the dovetail groove 4441. A connecting rod 4454 is arranged between the upper and lower corresponding side ear plates 4453. The two ends of the connecting pipe rod 4454 pass through the side ear plates 4453 and are matched with pipe caps 4455. The pipe caps 4455 at both ends are tightened and abut against the clamping plates 4451, so that the clamping plates 4451 clamp the battery. Shock-absorbing pads 4456 are embedded on the outer end surfaces of the pipe caps 4455, and heat dissipation holes 4457 are evenly distributed on the plate surface of the clamping plates 4451.

[0076] In the above technical solution, the dovetail groove 4441 is used in conjunction with the side ear plate 4453 to achieve accurate sliding of the clamping plate 451.

[0077] The battery is clamped by the clamping plate 4451, so as to fix the battery and make it more stable during operation.

[0078] By locking the tube cap 4455, the clamping plates 4451 on both sides can clamp the battery.

[0079] The provision of the shock-absorbing pad 4456 enables the battery to withstand the impact force of the upper and lower docking when sliding in.

[0080] Secondly, the shock-absorbing pad 4456 is made of rubber and can play an insulating role.

[0081] The rubber protrusion 4452 is designed to fix the battery and maintain a gap between the battery and the mounting plate to help dissipate heat.
