First line pipe 610 is kept away from the one end intercommunication of fire prevention base 410 has tangent urceolus 630, fixed mounting has tangent mechanism 650 in the tangent urceolus 630, tangent urceolus 630 one end is equipped with driven gear 640, tangent mechanism 650's rotating part and driven gear 640 fixed connection. The one end intercommunication that first walking pipe 610 was kept away from to tangent urceolus 630 has second walking pipe 620, the structure of second walking pipe 620 is the same with first walking pipe 610, just second walking pipe 620 and first walking pipe 610 set up with tangent urceolus 630 length direction's central line symmetry. First line pipe 610 one side of walking is equipped with servo motor 660, the transmission is connected with drive gear 670 on the servo motor 660 output, drive gear 670 top extend to in the tangent line urceolus 630, and with driven gear 640 meshing connection.
The wire cutting mechanism 650 includes a wire cutting inner barrel 651. For example, as shown in fig. 9, the tangent inner cylinder 651 is fixedly installed in the tangent outer cylinder 630, and a central through hole is formed in the center of the tangent inner cylinder 651. And the central axis of the tangent inner cylinder 651 coincides with the central axis of the tangent outer cylinder 630. A sliding cavity 680 is formed in the tangent inner cylinder 651, a sliding ring 652 is mounted on the inner wall of one side, away from the central axis of the tangent inner cylinder 651, of the sliding cavity 680, and the central axis of the sliding ring 652 is overlapped with the central axis of the tangent inner cylinder 651. A plurality of groups of second sliding blocks 653 are distributed on the sliding ring 652 in an annular array, a gear connecting rod is fixedly mounted on the second sliding blocks 653, and the other end of the gear connecting rod is fixedly mounted on the driven gear 640. A plurality of groups of inclined sliding grooves 654 are distributed on the inner wall of the sliding cavity 680 on one side close to the central axis of the tangent inner cylinder 651 in an annular array, the number of the inclined sliding grooves 654 is the same as that of the second sliding blocks 653, the inclined sliding grooves 654 are arranged in an inclined manner, and the distances from the two ends to the central axis of the central through hole are different. A spring connecting rod 655 is slidably connected in the inclined sliding slot 654, a connecting spring 656 is mounted at the other end of the spring connecting rod 655, and the other end of the connecting spring 656 is mounted on the corresponding group of second sliders 653. A cutter connecting rod 657 is mounted on the spring connecting rod 655, the other end of the cutter connecting rod 657 extends into the central through hole, and an electric wire cutter 658 is fixedly mounted on the cutter connecting rod 657.
When the storage battery works normally, the connecting wires of the storage battery are wound on the winding rods 612 of the first wiring pipe 610 and the second wiring pipe 620. When the second smoke sensor detects a fire in the fire protection unit 400 or in the cavity of the main housing 100, a signal is immediately sent to the servo motor 660, so that the servo motor drives the transmission gear 670 to rotate, and then the driven gear 640 and each group of second sliders 653 are driven to rotate simultaneously by the transmission gear 670. Then the spring connecting rod 655 is driven to slide from one end of the inclined sliding groove 654 far away from the central axis of the central through hole to the other end, and the wire cutter 658 is driven to move towards the central axis of the central through hole, and then a plurality of groups of wire cutters 658 distributed in an annular array are used for cutting the wires from different directions, thereby improving the cutting effect. Not only avoided the intensity of a fire to propagate through the connecting wire, also avoided battery 500 to pull the connecting wire to the in-process that always casing 100 removed outward simultaneously to cause the injury to interface department. The battery 500 is also protected from damage while improving the fireproof effect.
The embodiment has the following beneficial effects:
1. when the group of storage batteries 500 is spontaneously combusted or other components in the main casing 100 are combusted, the electric lifting block 413 falls down and pushes the battery mounting plate 420 to move under the action of the pushing spring 440, then the battery mounting plate 420 pushes the sealing door 120 open, the first slide rail 121 is communicated with the second slide rail 412, and then the battery mounting plate 420 drives the storage batteries 500 to move out of the main casing 100. So that it is quickly isolated from other batteries 500 and other components to prevent the spread of fire. Under the condition that the staff can not arrive at the site at the first time, the self-protection function is realized, and the safety of the storage battery module is improved.
2. When a fire occurs in the fire protection unit 400 or in the cavity of the main housing 100, the servo motor 660 drives the transmission gear 670, the driven gear 640 and the second sliding blocks 653 to rotate, and then drives the spring connecting rod 655 to slide from one end of the inclined sliding groove 654 away from the central axis of the central through hole to the other end, and accordingly, the wire cutter 658 is pushed to move towards the central axis of the central through hole, so as to automatically cut the connecting wire. Not only avoided the intensity of a fire to propagate through the connecting wire, also avoided battery 500 to drag the connecting wire to the in-process that total casing 100 moved outward simultaneously to cause the injury to interface department. The battery 500 is also protected from damage while improving the fireproof effect.
3. The smoke generated by the self-ignition of the battery 500 floats upwards and contacts the first arc groove 451, and because the section of the smoke has a fan-shaped annular structure, the smoke continues to gather to the highest position of the center of the first arc groove 451 and finally enters the second arc groove 452. Then enters the smoke exhaust pipe 470 through each set of smoke exhaust passages 460 and then is exhausted by the exhaust fan. The smoke exhaust speed is accelerated, smoke is prevented from repeatedly wandering in the cavity of the fireproof base 410 and the fireproof top plate 450, and the smoke exhaust effect is improved.
4. During normal operation, the connecting wire is wound in the spiral winding groove 613, so that the connecting wire is prevented from knotting. And when the connecting wire is on fire due to overlarge fire, dry powder is directly sprayed on the wire through a plurality of groups of high-pressure nozzles 614 which are arranged at equal intervals, and fire extinguishing operation can be carried out no matter where the ignition point is. Thereby avoiding the spread of fire.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
