Description

Technical Field

[0001] The invention relates to the field of battery manufacturing, in particular to a flooding type fire extinguishing charging and discharging device used for battery formation. Background Art

[0002] During the battery charging and discharging process, the battery needs to be charged and discharged to adjust and test the battery performance. This process is also called battery charging and discharging. Since the battery is charged and discharged with a large current for a long time, it is inevitable that the battery will have abnormalities and safety accidents, and fires will occur due to excessive temperatures. Most conventional charging and discharging equipment uses water and gas integrated fire protection. When the gas fire protection is released to extinguish the open fire, the battery is exposed to the air again, and there is still a possibility of re-ignition. In addition, the cost of gas fire protection is relatively high. There are also equipment that uses sprinkler water fire protection. When an accident occurs in a warehouse, the sprinkler will spray water onto the probe. This warehouse will no longer be able to continue production in a short period of time, which will affect the use of the entire array of equipment and greatly affect the production efficiency and safety of battery manufacturers. Summary of the invention

[0007] When sensing abnormal battery temperature, the infrared temperature sensor 406 transmits a battery fire alarm signal to an external industrial computer, and the external industrial computer sends a command signal to the submersible cylinder 401, which pushes the feed component 400, the lifting platform 408 and the battery tray into the water tank assembly 3.

[0008] More specifically, the top frame member 10 is provided with a static electricity detection sensor 104 .

[0009] More specifically, a tray damping block 4002 is provided on the top of the feeding component 400 to limit the lateral position of the battery tray when conveying the battery tray.

[0010] More specifically, the water tank assembly 3 includes a water tank body 301; a water inlet 302 and an overflow port 303 to prevent the water level from being too high are provided on the side of the water tank body 301, and a water outlet 304 for drainage is provided at the bottom; the valve structure at the front of the water tank body 301 can be opened to facilitate the removal of submerged equipment for cleaning and replacement.

[0012] Before inserting the battery tray, the present invention reduces the distance between the feeding component 400 and the lifting platform 408 through the feeding cylinder 407, and the feeding pulley 4001 on the feeding component 400, the infrared temperature sensor 406 and the tooling electric needle 403 pass through the through hole 409 on the lifting platform 408, exposing the upper surface of the lifting platform 408.

[0013] When loading begins, the battery tray is placed into the loading component 400 from the loading roller 13 at the front end of the frame middle frame 19 through the external loading mechanism. After the battery tray is pushed in, it is transported backwards through the feeding pulley 4001 located at the top of the lifting platform 408 and is limited by the limit block 402. After the infrared temperature sensor 406 detects that the battery tray is in place, the lifting platform 408 and the feeding component 400 are separated from each other under the push of the loading cylinder 407. The feeding pulley 4001 that passes through the lifting platform 408 and contacts the bottom of the battery tray descends together with the feeding component 400 and no longer contacts the battery tray. At this time, the battery tray is completely placed on the lifting platform 408. Then, the piston rod of the tray clamping cylinder 105 on the top frame component 10 is pushed out to clamp the battery tray between the clamping cylinder 105 and the lifting platform 408. Then, the needle plate movement cylinder 11 pushes the probe mechanism 2 to press and contact the poles of the battery on the battery tray for charging and discharging.

[0014] During the process of charging and discharging the battery, when the temperature of the battery tray is too high and a fire occurs, the infrared temperature sensor 406 detects the abnormal temperature and transmits a fire alarm signal to the upper computer. Then, the upper computer controls the device to cut off the power, and controls the piston rod of the sinking cylinder 401 to push downward, pushing the lifting platform 408, the battery tray and the feeding component 400 to sink into the water tank assembly 3 together, while the probe mechanism 2 and the rack middle frame 19 remain in place and are not submerged. The battery tray completes the fire by isolating the air, and the external staff opens the valve at the rear end of the water tank assembly 3 to replace the submerged components.

[0015] The technical effect of the present invention is that the lifting platform used to prevent the battery tray from sinking into water for fire extinguishing is separated from the rack middle frame. During fire extinguishing, only the battery tray, the lifting platform and the feeding components are sunk into water and replaced by external staff. There is no need to sink the charging and discharging probes and the entire rack middle frame, which improves the safety of the equipment and reduces the parts that need to be cleaned, thereby saving time and cost for equipment maintenance.
