Description

Technical Field

[0001] The utility model relates to the field of battery outer boxes, in particular to a battery outer box with a fire prevention warning component. Background Art

[0002] Lithium batteries are batteries that use lithium metal or lithium alloy as anode materials and non-aqueous electrolyte solutions. Box-type lithium batteries are one of the many types of lithium batteries. Box-type lithium batteries are a type of lithium battery that connects multiple lithium batteries in series and combines them in a box. Box-type lithium batteries have a large power storage capacity and are suitable for outdoor high-power electrical appliances, such as electric vehicles, electric bicycles, electric buses, etc. During the use of box-type lithium batteries, the lithium battery has a large operating current and generates a lot of heat, and the box-type lithium battery is in a sealed space, which leads to a higher operating temperature of the lithium battery in the box. When the outdoor temperature is high, the temperature outside the box is also high, and the lithium battery is in a high-temperature working state, which is prone to fire or explosion, and there are major safety issues, so heat dissipation measures need to be taken.

[0003] Chinese patent number CN202122471395.1 discloses a power distribution control cabinet with a fire warning function, including a cabinet body, a fan is arranged on the bottom surface of the cabinet body, a carrying box is arranged above the fan, a component slot is arranged in the carrying box, an air inlet slot is arranged on one side of the component slot, an air guide plate is arranged above the side of the air inlet slot away from the component slot, a protective plate is arranged on one side of the cabinet body, a rotating rod is arranged on the side of the carrying box close to the protective plate, a connecting block is arranged on the rotating rod, a sealing plate is arranged on one side of the connecting block, supporting feet are arranged on the bottom of the cabinet body, ventilation slots are arranged on the top and both sides of the cabinet body, a temperature sensor is arranged on the side of the cabinet body away from the fan, and a smoke sensor is arranged on one side of the temperature sensor.

[0004] From the above, it can be seen that by providing a carrying box and a component slot, the instrument lines can be installed separately at different positions inside the cabinet. With the movable connection between the rotating rod and the connecting slot, the sealing plate of the component slot where the faulty instrument is located can be quickly opened, so that the faulty instrument can be repaired. However, this case still has the following shortcomings: in daily use of the battery outer box, dust is inevitably likely to enter the interior of the body. The battery outer box has heat dissipation holes that are open to the outside, and a certain amount of dust will enter the interior of the battery outer box through the holes. Years of accumulation will greatly reduce the life of the internal components.

In the prior art, installation and disassembly are relatively cumbersome, and cleaning is often time-consuming and labor-intensive, increasing the labor intensity of personnel.

[0005] Therefore, in order to solve the above problems, a battery outer box with a fire warning component is proposed. Utility Model Content

[0025] During operation, when dust in the air enters the interior of the connection chamber 21 through the gap, the dust is guided and adsorbed with the cooperation of the anode electric coil 25 and the cathode electric coil 26. The installation of the dust filter 27 prevents the entry of large solid particles, which is beneficial to the protection of internal components.

[0026] Furthermore, the box body 1 is installed with a protective shell 11, a display panel 12 is fixedly installed on the front side of the protective shell 11, a sealing cover 13 is movably installed on the back side of the protective shell 11, and an interface 14 is opened on the back side of the protective shell 11;

[0027] During operation, the protective shell 11 protects the internal battery, and the installation of the sealing cover 13 helps to prevent water or foreign objects from entering the interface 14.

[0028] Furthermore, two collecting buckets 28 are movably connected to the top of the connecting plate 31, and one side of the two collecting buckets 28 is fixedly connected with a pull ring 29 respectively;

[0029] During operation, the dust is collected into the collecting bucket 28 under the action of the electric field force, and it is convenient for personnel to take it out through the pull ring 29 to clean the dust.

[0030] Furthermore, the connection chamber 21 is provided with four grooves and respectively fixedly installed with cooling fans 23, a baffle 24 is fixedly installed on both sides of the connection chamber 21, and a protective plate 22 is fixedly connected to the bottom of the connection chamber 21;

[0031] During operation, when the temperature of the battery reaches a threshold, the cooling fan 23 is driven to promptly dissipate heat inside the battery, and the barrier 24 prevents large foreign objects from entering during the heat dissipation operation.

[0032] Furthermore, a humidity sensor 33 is fixedly installed on the top of the connecting plate 31, a temperature sensor 34 is fixedly installed on the top of the connecting plate 31, a control mainboard 35 is fixedly installed on the top of the connecting plate 31, and the connecting plate 31 is provided with two heat dissipation slots 32;

[0033] During operation, the internal temperature and humidity are monitored in real time through the humidity sensor 33 and the temperature sensor 34, which is beneficial for early warning in special circumstances.

[0036] Working principle: The heat dissipation is performed as a whole. The heat dissipation through the fan will cause a large amount of dust to enter the body. By energizing the anode coil 25 and the cathode coil 26 at the same time, a high-voltage electric field is generated between the anode coil 25 and the cathode coil 26 when they are energized. When the air enters the interior of the connecting chamber 21, it enters the high-voltage electric field, and corona discharge occurs through the cathode coil 26, so that the gas is ionized. At this time, the negatively charged gas ions move toward the cathode coil 26 under the action of the electric field force, and collide with dust particles during the movement, so that the dust is negatively charged. The charged dust moves toward the anode coil 25 under the action of the electric field force. After reaching the anode coil 25, the charged dust releases its own electrons, so that the dust is adsorbed on the surface of the anode coil 25. When a certain weight is accumulated, the dust falls by its own weight and falls into the collection bucket 28 for collection. When it is collected to a certain extent, the personnel take out the collection bucket 28 from the interior of the connecting chamber 21 through the pull ring 29 to clean the collected dust.
