Description

Technical Field

[0001] This utility model belongs to the field of new energy technology, specifically, it relates to an automatic fire extinguishing device and a battery box. Background Technology

[0002] With the development of the new energy battery industry, battery boxes, as independent battery units, are increasingly favored by the market and customers due to their small size, light weight, and high reliability. In order to increase the capacity of battery boxes, multiple individual batteries are usually set inside the battery box. During the assembly process, multiple individual batteries need to be installed into the box in sequence.

[0003] Chinese patent CN222705701U discloses a battery box for accommodating multiple single cells. The multiple single cells are stacked in a direction perpendicular to their main surface. The battery box includes multiple plates that together form an inner cavity for accommodating the multiple single cells. One plate is fixedly disposed opposite to the main surface, and another plate opposite to the main surface is provided with a sliding block. Other plates connected to the plate with the sliding block are provided with sliding grooves that extend in a direction perpendicular to the main surface. The sliding block is slidably disposed in the sliding groove so that the plate with the sliding block can apply a pre-tightening force to the multiple single cells. In the conventional battery boxes mentioned above, multiple sets of batteries are often directly connected in parallel. Once one battery catches fire, it often spreads rapidly to all batteries, causing them to burn without time to be extinguished, thus amplifying the overall damage. The sudden burning of the batteries can also cause power outages, affecting the power supply and causing additional losses.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automatic fire extinguishing device and battery box, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An automatic fire extinguishing device and battery box, comprising: a enclosure panel, characterized in that a base plate is provided on the inner side of the enclosure panel near the bottom, a short baffle and a long baffle are vertically provided on the top of the base plate, the short baffle and the long baffle divide the interior of the enclosure panel into multiple battery compartments, batteries are provided at the bottom of the battery compartments, a support plate is provided on the top of the batteries, a fire extinguishing box is provided on one side of the top of the support plate, a coolant tank and a pressurizing device are provided inside the fire extinguishing box, and a control box is provided on the other side of the top of the support plate.

[0008] Optionally, the top of the control box is provided with a series assembly, the series assemblies are connected to each other by connecting pipelines, and a docking plate is provided on one side of the enclosure, the surface of the docking plate is installed with an interface.

[0009] Optionally, the battery is composed of two identical battery cells connected in series.

[0010] Optionally, a baffle mounting block is provided between the short baffle and the long baffle, and the baffle mounting block has slots on all four sides.

[0011] Optionally, the short baffle is provided with a pad on its side wall.

[0012] Optionally, the bottom of the base plate is provided with heat dissipation holes, and the bottom of the long baffle is provided with a heat dissipation plate.

[0013] Optionally, the fire extinguishing box is provided with a cover plate on top, and the cover plate is provided with a pivot on the top of the long baffle.

[0014] Optionally, the coolant tank inside the fire extinguishing box can be replaced.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0016] 1. This automatic fire extinguishing device and battery box are equipped with a separate control box for each battery group and connected in series. This allows the device to shut off the power supply to any one or more battery groups without affecting the overall continuous power supply. The control box detects the battery temperature. When a single battery catches fire, the pressurization device quickly sprays the coolant from the coolant tank onto the battery to isolate the air and extinguish the fire. The series components cut off the power supply while the other batteries continue to operate normally, thus not affecting the overall power supply and preventing sudden power outages. Both the fire extinguishing box and the battery can be disassembled and replaced to reduce subsequent maintenance costs.

[0017] 2. The automatic fire extinguishing device and battery box have through holes at the bottom of the base plate and heat dissipation holes at both ends to connect to the outside. A long baffle that fits the surface of the battery passes through the base plate and extends to the bottom of the heat dissipation plate. The heat dissipation holes at both ends allow outside air to pass through and carry away the heat of the heat dissipation plate, thereby absorbing the heat of the battery and preventing it from overheating.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] Please see Figure 1-6 As shown, this embodiment provides an automatic fire extinguishing device and a battery box, including: a surrounding panel 1.

[0032] like Figure 1-4As shown, in this embodiment, a bottom plate 8 is provided on the inner side of the enclosure 1 near the bottom. A short baffle 6 and a long baffle 7 are vertically arranged on the top of the bottom plate 8, dividing the interior of the enclosure 1 into multiple battery compartments 5. Batteries 14 are placed at the bottom of each battery compartment 5, and a support plate 12 is placed on top of each battery 14. A fire extinguishing box 13 is located near one side of the top of the support plate 12, containing a coolant tank 1301 and a pressurizing device 1302. A control box 11 is located near the other side of the top of the support plate 12. The enclosure 1 and the bottom plate 8 constitute the outer shell of the entire battery box. The long baffle 7 and short baffle 6 are evenly and perpendicularly distributed inside, dividing the internal space of the battery box into multiple battery compartments. Batteries 14 are placed at the bottom of each battery compartment, and the support plate 12 is covered. The control box 11 connects the battery 14 and the fire extinguishing box 13. The control box 11 is equipped with a temperature sensor that can monitor the temperature of the battery 14. When the battery catches fire due to a malfunction, the temperature inside the battery compartment reaches its maximum value. The control box 11 connects to the pressurization device 1302 inside the fire extinguishing box 13. The pressurization device 1302 opens the connection switch between the fire extinguishing box 13 and the battery compartment, so that the high-pressure coolant in the coolant tank 1301 is sprayed onto the battery 14 through the pressurization device 1302 and through the tray 12, covering the battery and reducing the battery temperature to achieve the purpose of extinguishing the fire. Each group of batteries is equipped with a separate control box 11 and fire extinguishing box 13, so that the monitoring of each battery 14 is independent of each other. The fire of one or more groups of batteries 14 does not affect the normal operation of other batteries 14.

[0033] like Figure 1 As shown, the top of the control box 11 in this embodiment is provided with a series assembly 3, which is connected to each other by a connecting pipeline 301. A docking plate 2 is provided on one side of the enclosure 1, and an interface 201 is installed on the surface of the docking plate 2. The output end of the battery 14 is connected to the control box 11, and then connected to the interface 201 of the docking plate 2 through the series assembly 3. The device is connected to the battery box through the insertion interface 201 so that the battery 14 can be powered. The series assembly 3 allows the line of each battery 14 to be connected to the connecting pipeline 301 independently. Each battery 14 is independent of each other. The failure of the front battery 14 to supply power does not affect the continuous power supply of the rear battery 14. This allows the other batteries to continue to supply power when one or more sets of batteries 14 catch fire or fail for other reasons. The power supply of the overall battery box is weakened but not interrupted, ensuring that the device will not experience a power outage. For the battery 14 that stops supplying power, the signal transmitter in the control box 11 sends a fault signal to the terminal to remind the operator to replace the battery.

[0034] like Figure 4 As shown, the individual battery 14 has two sub-batteries installed independently and connected to the control box 11 by separate wiring, ensuring that the other sub-battery can continue to work and maintain power output when one sub-battery fails, without affecting the overall power supply.

[0035] like Figure 6 As shown, in this embodiment, a baffle mounting block 9 is provided between the short baffle 6 and the long baffle 7. The baffle mounting block 9 has slots 901 on all four sides. Multiple baffle mounting blocks 9 are fixedly installed on the base plate 8. The slots 901 with four openings can be inserted into the short baffle 6 and the long baffle 7 respectively, thereby fixing the two baffles and reducing the difficulty of disassembling the baffles, making the entire battery box easier to install.

[0036] like Figure 2 As shown, the short baffle 6 in this embodiment is provided with a pad 10 on its side wall; wherein, during installation, the side wall of the battery 14 is attached to the long baffle 7, and the short baffle 6 is blocked by the pad 10, so that a gap is created between the two, which facilitates the installation and fixing of the battery 14. At the same time, the pad 10 abuts against the battery 14 to prevent it from shaking. The pad 10 at the higher position can support the support plate 12, thereby facilitating the installation of the control box 11 and the fire extinguishing box 13.

[0037] like Figure 1 , 3 As shown in Figure 5, the bottom of the base plate 8 in this embodiment is provided with heat dissipation holes 101, and the bottom of the long baffle 7 is provided with a heat dissipation plate 701. The long baffle 7 extends downward through the base plate 8 to form an additional heat dissipation plate 701. The two heat dissipation plates 701 are bent inward, and the teeth on the surface interlock and are fixed together. A cavity is left below the base plate 8, which is connected through the heat dissipation holes 101 at both ends to form a flow channel. The battery 14 in the battery compartment 5 is attached to the long baffle 7 to absorb the heat generated by the battery 14. The heat is distributed from the long baffle 7 to the heat dissipation plate 701. Outside air enters from one side, passes through the heat dissipation plate 701, takes away the heat of the heat dissipation plate 701, and then is discharged, thereby achieving the cooling of the battery 14.

[0038] like Figure 1 As shown, the fire extinguishing box 13 in this embodiment is provided with a cover plate 4 on the top, and the cover plate 4 is provided with a rotating shaft on the top of the long baffle 7; wherein, two cover plates 4 are installed on the rotating shaft and rotate independently of each other, covering the battery compartments 5 on both sides, one on the left and one on the right, to cover and protect the fire extinguishing box 13.

[0039] like Figure 2 As shown, the coolant tank 1301 inside the fire extinguishing box 13 in this embodiment can be replaced. The fire extinguishing box 13 can be opened by flipping open the cover plate 4, and the coolant tank 1301 can be removed for replacement. After the fire extinguishing box 13 extinguishes the fire, the control box 11 and the fire extinguishing box 13 on the tray 12 are taken out, the internal coolant tank 1301 is replaced, a new battery 14 is installed, and the tray 12 is placed on top to connect the control box 11. After the replacement, the corresponding battery compartment 5 starts working again.

[0040] Working principle: The enclosure 1 and the base plate 8 are combined to form the battery box shell. The short baffle 6 and the long baffle 7 are inserted into the slots 901 of the baffle mounting block 9 on the base plate 8 in sequence, thereby dividing it into multiple battery compartments 5. The battery 14 is placed in the battery compartment 5 and fits against the side of the long baffle 7. The top is supported by the pad block 10 and a tray 12 is placed in it. The control box 11 passes through the tray 12 and is connected to the battery 14. The fire extinguishing box 13 is installed on the other side. The nozzle passes through the tray 12 and is aimed at the top of the battery 14. Finally, the cover plate 4 is closed. The top of the control box 11 is connected to multiple series components 3 through the connecting pipe 301 and finally connected to the interface 201 of the docking plate 2. It is powered by an external device. Each battery 14 is connected separately. If a single battery 14 catches fire and loses power, it will not affect the overall continuous power supply, so as to ensure that the equipment will not suddenly lose power.
