Description

[Technical Field]

[0001] The present invention relates to the field of battery manufacturing, and more particularly to a submerged fire-extinguishing charging and discharging facility used in battery chemical formation. [Background technology]

[0002] During battery charging and discharging, batteries must be charged and discharged to adjust and test their performance. This process is also known as battery capacity charging and discharging. Charging and discharging batteries for long periods of time at high currents inevitably leads to battery abnormalities and safety hazards, and excessive temperatures can lead to fires. Most conventional charging and discharging equipment uses integrated water and gas firefighting. Even after the fire gas is released and the flames are extinguished, there is still a risk of re-ignition if the battery is re-exposed to air. Gas firefighting is also relatively expensive. Sprinkler-type water firefighting equipment is sometimes used. However, if an accident occurs in one section and the sprinkler sprays water onto the probe, that section will be unable to continue production for a short period of time, affecting the use of the entire equipment and significantly impacting the production efficiency and safety of battery manufacturers. Summary of the Invention

[0003] In order to solve the above problems, the present invention proposes a submersible fire extinguishing charging / discharging equipment. The concept is to separate the table that raises and lowers the battery tray from the frame middle, and to improve the probe mechanism that docks with the battery tray, thereby increasing the docking accuracy with the battery when charging / discharging the equipment and reducing damage to the equipment caused by submerged fire extinguishing.

[0004] The submersible fire extinguishing charging and discharging equipment of the present invention includes a rectangular parallelepiped outer frame 7, and a plurality of frame assemblies 1 are installed along a straight line inside the outer frame 7. The direction in which the frame assemblies 1 are arranged in order is defined as the horizontal direction, and the direction perpendicular to the horizontal direction is defined as the vertical direction. The frame assembly 1 includes a rectangular frame bottom frame 17, which is connected to an upper frame member 10 above by a support pillar 12. A frame middle frame 19 is provided between the frame bottom frame 17 and the upper frame member 10, and a water tank is provided between the frame bottom frame 17 and the frame middle frame 19. The frame middle frame 19 is provided with a battery assembly 3, and one pin plate movement cylinder 11 is installed at each of the lateral ends of the frame middle frame 19. The side where the two pin plate movement cylinders 11 face each other is defined as the inside, and the side where they are apart is defined as the outside. One vertical end of the frame middle frame 19 is fitted with a load roller 13 for introducing an external battery tray. The end where the load roller 13 is located is the front end, and the other end is the rear end. The upper frame member 10 is fitted with a power supply for charging and discharging the battery, a flue exhaust port 102, and a probe heat dissipation fan for dissipating heat from the battery. The battery tray is provided with a pin plate 103 and a tray clamp cylinder 105 for supporting the battery tray. A probe mechanism 2 for supplying power to the battery electrodes in the battery tray is connected to the inside of each of the two pin plate movement cylinders 11. A water tank assembly 3 is provided between the frame bottom frame 17 and the frame middle frame 19. A bottom plate mechanism 16 is provided at the bottom of the cavity of the water tank assembly 3. A lift transport mechanism 4 is connected on the bottom plate mechanism 16. The lift transport mechanism 4 includes a vertical guide column 404. The bottom of the guide column 404 is connected to the bottom of the bottom plate mechanism. 16 is connected, a horizontal feed member 400 is provided on the top of the guide column 404, two rows of feed pulleys 4001 are provided on the top of the feed member 400 in a vertical direction, an infrared temperature sensor 406 and a tool power attachment pin 403 are provided between the two rows of feed pulleys 4001, a lift table 408 is fitted on the top of the feed member 400, and a through hole 409 is left in the center of the lift table 408, through which the feed pulleys 4001, the infrared temperature sensor 406 and the tool power attachment pin 403 pass,A load cylinder 407 is connected between the feed member 400 and the lift table 408 to adjust the distance between them. A battery tray is placed on top of the lift table 408. The battery tray is located between the two probe mechanisms 2 and at the same height as the probe mechanisms 2. A battery tray position limiting stopper 402 is provided at the rear end of the upper surface of the lift table 408. The piston rod of a submerged cylinder 401 is connected to the lift table 408. The submerged cylinder 401 is fixedly connected to the frame middle frame 19. The feed member 400 and lift table 408 are slidably installed on guide posts 404. When an abnormal battery temperature is detected, an infrared temperature sensor 406 transmits a battery fire alarm signal to an external industrial PC. The external industrial PC sends a command signal to the submerged cylinder 401, which then pushes the feed member 400, lift table 408, and battery tray into the water tank assembly 3.

[0005] More specifically, the upper frame member 10 is provided with a static electricity detection sensor 104 .

[0006] More specifically, the top of the feed member 400 is provided with a tray damping block 4002 for limiting the lateral position of the battery trays when transporting them.

[0007] More specifically, the water tank assembly 3 includes a water tank body 301, the side of which is provided with a water intake 302 and an overflow port 303 to prevent the water level from rising too high, and the bottom is provided with a water outlet 304 for drainage. The valve structure at the front of the water tank body 301 can be opened to facilitate removal of submerged equipment for cleaning and replacement.

[0008] More specifically, the outer frame 7 is provided with an electrical cabinet 73 including a programmable logic controller (PLC), an alarm lamp 75 is provided at the top of the outer frame, a horizontal slide rail 72 is provided at the top of the outer frame, a slidable touch screen 71 is provided on the horizontal slide rail 72, and the outer frame 7 is provided with multiple emergency exits 74 at the same height.

[0009] In the present invention, before the battery tray is inserted, the distance between the feed member 400 and the lift table 408 is adjusted and reduced by the load cylinder 407, so that the feed pulley 4001, infrared temperature sensor 406, and tool power supply pin 403 on the feed member 400 pass through the through hole 409 on the lift table 408 and are exposed on the upper surface of the lift table 408.

[0010] When loading begins, the battery tray is inserted into the feed member 400 through the load roller 13 at the front end of the frame middle frame 19 via an external load mechanism. As the battery tray is pushed in, it is transported backward by a feed pulley 4001 located at the top of the feed member 400, and its position is limited by a position limiting stopper 402. When an infrared temperature sensor 406 detects the arrival of the battery tray, the load cylinder 407 pushes the lift table 408 and feed member 400 apart, and the feed pulley 4001, which passes through the lift table 408 and is in contact with the bottom of the battery tray, descends together with the feed member 400 and no longer contacts the battery tray. At this time, the battery tray is placed completely flat on the lift table 408. The piston rod of the tray clamp cylinder 105 on the upper frame member 10 is then pushed out, clamping the battery tray between the tray clamp cylinder 105 and the lift table 408. Thereafter, the pin plate moving cylinder 11 pushes the probe mechanism 2 to bring it into pressure contact with the poles of the battery on the battery tray, thereby carrying out charging and discharging.

[0011] If the battery tray temperature becomes too high during battery charging / discharging, causing a fire, the infrared temperature sensor 406 detects the abnormal temperature and transmits a fire alarm signal to the host machine. The host machine then controls the equipment to cut off power and controls the piston rod of the submersion cylinder 401 to push it downward, pushing the lift table 408, battery tray, and feed member 400 together and submerging them into the water tank assembly 3, but the probe mechanism 2 and frame inner casing 19 remain in their original positions and do not submerge. Once the fire in the battery tray has been extinguished by cutting off the air, an outside worker opens the valve at the rear end of the water tank assembly 3 and replaces the submerged members.

[0012] The technical effect of the present invention is that the lift table for submerging the battery tray in water to extinguish the fire is separated from the frame middle section, and when extinguishing a fire, only the battery tray, lift table, and feed member are submerged and replaced by external workers, eliminating the need to submerge the charging / discharging probe or the entire frame middle section, improving the safety of the equipment and reducing the number of parts that need to be cleaned, thereby saving time and costs in equipment maintenance.

A valve at the front of the water tank body 301 can be opened to make it easier to remove submerged equipment for cleaning and replacement. Referring to Figure 5, a lifting and transporting mechanism 4 is provided in the center of the frame middle frame 19 and connected to the frame bottom frame 17. The lifting and transporting mechanism 4 can rise and fall independently of the frame middle frame 19, and can play the role of lifting and transporting the battery tray. The frame bottom frame 17 is provided withA vertical guide column 404 is connected via the motion axis fixing welded plate 16 and the guide column fixing member 405 in this order, and the guide column 404 passes through the water tank assembly 3. A horizontal feed member 400 is provided on the top of the guide column 404, and two rows of feed pulleys 4001 arranged vertically, an infrared temperature sensor 406, and a tool power supply pin 403 are provided on the top of the feed member 400. A lift table 408 is mounted on the top of the feed member 400, and the feed pulleys 4001, the infrared temperature sensor 406, and the tool power supply pin 403 pass through through holes on the lift table 408. A load cylinder 407 is provided between the feed member 400 and the lift table 408, and one battery tray is placed on the top of the lift table 408. The battery tray is located between the two probe mechanisms 2 and is at the same height as the probe mechanisms 2.
