The reference numbers in the figures indicate:
fire extinguisher shell 1, right rotating shaft 2, left rotating shaft 3, sealing washer 4, right turning plate 5, left turning plate 6, dry powder storage area 7, pressure sensor 10, motor 11 and turning plate supporting block 12
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Example 1
As shown in figure 1, the bottom of the battery pack fire extinguisher is provided with a turning plate which is connected to a fire extinguisher shell 1 through a turning mechanism and sealed between a sealing gasket 4 and the shell 1. The turnover mechanism comprises a rotating shaft on the fixed shell 1, a motor 11 for driving the turnover plate to rotate around the rotating shaft, and a turnover plate supporting block 12 (shown in figure 2) connected with the motor 11. In addition, a motor 11 is mounted on the case 1, and a pressure sensor 10 for sensing a change in the internal temperature of the battery is mounted thereunder. A plurality of partitions may be disposed within the housing 1 to divide the interior of the housing 1 into a plurality of regions, each of which may store a different function of fire suppressant or other function of substance. In this embodiment, as shown in fig. 1, the inside of the housing 1 is divided into two fire extinguishing material storage areas 7, the bottom of each fire extinguishing material storage area 7 is provided with a turning plate, namely a right turning plate 5 and a left turning plate 6, the fixed end of the right turning plate 5 is provided with an axis and penetrates through the right rotating shaft 2, the fixed end of the left turning plate 6 is provided with an axis and penetrates through the left rotating shaft 3, the free ends of the right turning plate 5 and the left turning plate 6 are supported by a turning plate support block 12, and when the fire extinguishing device does not work, the bottom of the fire extinguishing device is separated from the battery pack 9 by the right turning.
Under normal working conditions, dry powder is stored in the area 7 by the right and left flaps 5, 6. When an abnormality occurs in the battery pack 9, the pressure of the battery pack 9 rises. When the pressure rises to a certain value, the pressure sensor 10 transmits a signal to the motor 11. The motor 11 controls the flap supporting block 12 to leave the right flap 5 or the left flap 6, and the right flap 5 or the left flap 6 can rotate around the right rotating shaft 2 or the left rotating shaft 3 under the action of self gravity. At this time, the dry powder stored in the region 7 falls down and covers the battery pack 9. The dry powder can isolate the components of the battery pack 9 from contacting with air, and prevent the exploded battery pack from continuously burning the electric vehicle. The partitioned dry powder storage areas 7 may also store other functional substances in special cases to protect or prevent the possible risks of the battery pack.
