Description

Technical Field

[0001] The present invention belongs to the technical field of battery manufacturing, and specifically relates to a submerged charging and discharging mechanism.

Background Art

[0002] During the charging and discharging process of a battery, it is inevitable that abnormalities and safety accidents occur in the battery due to charging and discharging the battery for a long time with a large current.

[0003] Currently, most ordinary charging and discharging equipment adopts a water-gas integrated fire extinguishing equipment and a sprinkler fire extinguishing equipment to handle abnormal situations of the battery. Among them, in the case of adopting the water-gas integrated fire extinguishing equipment to handle battery abnormalities, fire extinguishing gas is released, and after the fire goes out, the battery is still exposed to the air again, so there is still a possibility of re-ignition, and moreover, the cost of the fire extinguishing gas is quite high. In the case of adopting the sprinkler fire extinguishing equipment to handle battery abnormalities, after an accident occurs at a certain position, when the sprinkler sprays water on the probe, that position cannot continue production for a short period of time, which affects the use of the entire row of equipment, so it has the disadvantage of extremely greatly affecting the production efficiency and safety of battery manufacturers.

Summary of the Invention

[0004] In order to solve the above technical problems existing in the prior art, the present invention presents a submerged charging and discharging mechanism, which can not only achieve the purpose of rapid fire extinguishing, but also reduce the impact on other positions caused by the fire, and make the production by the equipment more flexible.

[0005] The technical means adopted by the present invention to solve its technical problems are as follows. A submerged charging and discharging mechanism, including a mechanism frame assembly, a water tank assembly, and a motion assembly, among which, The mechanism frame assembly includes an upper frame (1), a battery tray (2), and a middle frame (3). A needle plate used for charging and discharging is fixedly installed at the bottom of the upper frame (1). The extending direction of the long side of the middle frame (3) is defined as the front-rear direction, and the extending direction of the short side of the middle frame (3) is defined as the left-right direction. A plurality of battery trays (2) are installed at intervals in parallel along the left-right direction of the middle frame (3), and batteries are placed in the battery trays (2). The movement assembly includes a fire extinguishing movement cylinder (30) and a movement shaft (34). The movement shaft (34) is installed at the bottom of the upper frame (1). The upper end of the movement shaft (34) is fixedly installed on the upper frame (1), and the lower end is fixedly installed inside the water tank assembly. The middle frame (3) is installed between the upper frame (1) and the water tank assembly and can slide up and down along the movement shaft (34). The fire extinguishing movement cylinder (30) is fixedly installed on the upper frame (1), and the lifting end of the fire extinguishing movement cylinder (30) is connected to the middle frame (3) to slide the middle frame (3) up and down along the movement shaft (34). When the battery ignites, under the action of the fire extinguishing movement cylinder (30), the middle frame (3) sinks the battery into the water tank assembly to achieve the purpose of fire extinguishing.

[0006] Furthermore, the water tank assembly includes a water tank body (401). A water intake (402) is installed on the water tank body (401). The water intake (402) is connected to an external pipeline to store water in the water tank body (401). An outlet (404) for discharging the water in the water tank body (401) is installed at the bottom of the water tank body (401).

[0007] Furthermore, an overflow port (403) for preventing the liquid level in the water tank body (401) from being too high is installed at the upper end of the water tank body (401).

[0008] Furthermore, a connection plate (405) is installed at the bottom inside the water tank body (401), and the lower end of the movement shaft (34) is fixedly installed on the connection plate (405).

[0009] Furthermore, a smoke sensor is installed on the middle frame (3), and the smoke sensor is connected to a controller. After receiving the information from the smoke sensor, the controller sends a fire alarm and controls the movement of the fire extinguishing movement cylinder (30).

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows. 1. In the present invention, the smoke sensor detects and issues an alarm, triggers the fire extinguishing movement cylinder on the middle frame, and quickly throws the battery tray (with the battery installed therein) into the water tank body, immersing the battery in the water in the water tank body, so as to cut off the burned battery from oxygen and prevent re-ignition, thereby achieving the purpose of high-speed fire extinguishing. 2. In the present invention, the middle frame moves up and down along the movement axis, and the tray with the battery installed is submerged in the water tank body, thereby solving the possibility of battery re-ignition existing in the conventional fire extinguishing method. It has low cost, and the probe is not affected, and production at the position can be continued, so it does not affect the use of the entire row of equipment, and guarantees the production efficiency and safety of battery manufacturers. 3. In the present invention, damage to equipment caused by the normal fire extinguishing method can be reduced. Thereby, the occurrence of fires can be prevented and the hidden dangers of fires can be eliminated.
