After battery production, high and low temperature test chambers are used to test their high and low temperature resistance.

[0003] Announcement No. (CN221667556U) discloses an explosion-proof high and low temperature test chamber. Since a reciprocating nozzle is used to spray fire extinguishing agent to extinguish the fire inside the test chamber, the output shaft of the motor will drive the connecting rod to rotate, and the connecting rod will drive the disc to rotate, and the disc will drive the sliding rod to make a circular motion, and the sliding rod will drive the limit slide to move back and forth, and the limit slide will drive the mounting plate to move back and forth along the limit rod, and the mounting plate will drive the clamp to move back and forth, and the clamp will drive the main pipe to move back and forth, and the main pipe will drive the nozzle to move back and forth, so as to achieve fire extinguishing. The above device extinguishes the fire directly inside the test chamber, and the fire extinguishing agent may cause damage to the equipment inside the test chamber, which needs to be improved.

When the placement seat 205 descends to the middle position inside the fire extinguishing box 206, the cylinder 204 stops running, and then open the valve on the circular tube 209. The fire extinguishing agent in the storage box 210 enters the rectangular tube 207 through the circular tube 209, and the fire extinguishing agent in the rectangular tube 207 is sprayed out through the nozzle 208, so that the fire extinguishing agent is sprayed onto the surface of the battery. The battery is extinguished in the above manner, and the fire extinguishing process is not carried out inside the test box body 201, thus ensuring that the internal equipment of the test box body 201 will not be damaged.

The rotation of the bidirectional threaded rod 303 drives the two movable blocks 304 to move toward each other. The movable block 304 drives the closing plate 306 to move through the connecting rod 305. When the two closing plates 306 come into contact, the motor 302 stops running, and then the fire extinguishing agent can be sprayed. The two closing plates 306 work together to seal the rectangular through hole at the bottom of the test box body 201, thereby preventing the fire extinguishing agent from entering the interior of the test box body 201, further reducing the probability of damage to the internal equipment of the test box body 201.

[0032] In the above structure: when using the device, the battery to be tested is placed on the placement seat 205, and the box door 202 is closed after placement is completed, and then the battery can be tested. If a battery fire is found during the test, the cylinder 204 is started, and the cylinder 204 drives the placement seat 205 and the battery to descend. When the placement seat 205 descends to the middle position inside the fire extinguishing box 206, the cylinder 204 stops running, and the motor 302 is started. The motor 302 drives the bidirectional threaded rod 303 to rotate, and the bidirectional threaded rod 303 rotates to drive the two movable blocks 304 to move toward each other. The movable block 304 drives the closing plate 306 to move through the connecting rod 305. When the two closing plates 306 contact, the motor 302 stops running, and then the valve on the circular tube 209 is opened, and the fire extinguishing agent in the storage box 210 enters the rectangular tube 207 through the circular tube 209, and the fire extinguishing agent in the rectangular tube 207 is sprayed out through the nozzle 208, so that the fire extinguishing agent is sprayed onto the surface of the battery.
