Description

Technical Field

[0001] The utility model relates to a fire protection structure of a charging and discharging rack for a battery pack of a new energy vehicle, and belongs to the technical field of new energy power generation. Background Art

[0002] With the continuous development of the new energy vehicle industry, the demand for battery replacement is also increasing. A structure with a reasonable design that can place new energy vehicle battery replacement batteries in batches can effectively meet the demand for battery replacement for new energy vehicles.

[0003] However, there is a fire risk when swappable batteries are placed in batches. In the event of a lithium battery fire, if the battery pack that catches fire early can be isolated and disconnected from the battery system, the danger of a lithium battery fire can be greatly reduced. Utility Model Content

[0004] The utility model proposes a fire protection structure for a charging and discharging rack of a new energy vehicle battery pack replacement battery, the purpose of which is to overcome the above-mentioned deficiencies in the prior art and to achieve batch charging and storage of battery replacement batteries while ensuring good fire protection performance.

[0005] The technical solution of the utility model: a fire protection structure of a charging and discharging rack for battery packs of new energy vehicles, which includes a charging rack, a mechanical arm and a fire protection pool, wherein two rows of battery replacement batteries, each with several layers, are stored on the charging rack, and the battery replacement batteries are slidably connected to the slide rails on the charging rack through pulleys. A driving mechanism is installed on the top of the charging rack between the two rows of battery replacement batteries, and the driving mechanism is connected to the mechanical arm, and the lower end of the mechanical arm is connected to the battery grasping mechanism, and a fire protection pool is opened on the ground below the mechanical arm. When working, the battery grasping mechanism driven by the mechanical arm can remove or put back the battery replacement battery on the charging rack. If there is battery smoking or a fire hazard occurs, the battery grasping mechanism can put the battery replacement battery into the fire protection pool, away from other normal battery replacement batteries, effectively reducing the scale of the fire.

[0006] Preferably, a fire-resistant sealed upper cover is slidably connected to the top of the fire-fighting pool. After the battery enters, the upper cover can be closed to prevent water vapor from overflowing.

[0007] Preferably, the fire-resistant sealed upper cover is provided with a smoke exhaust pipe, so that smoke generated by the accident battery can be extracted through the pipe and discharged to a safe area.

[0008] The advantages of the utility model are as follows: the structural design is reasonable, the battery replacement can be removed and inserted by a manipulator, and when a fire occurs, the corresponding battery can be promptly thrown into the fire pool to reduce the fire hazard in time. Usually, the fire pool is close to the battery rack, which can realize the cold storage and cooling function. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1It is a structural schematic diagram of the fire protection structure of the charging and discharging rack of the utility model for the battery pack replacement of new energy vehicles.

[0010] In the figure, 1 is the battery replacement battery, 2 is the slide rail, 3 is the charging rack, 4 is the fire pool, 5 is the driving mechanism, 6 is the robotic arm, and 7 is the battery grabbing mechanism. DETAILED DESCRIPTION

[0011] The utility model is further described in detail below in conjunction with embodiments and specific implementation methods.

[0012] like Figure 1 As shown, a fire protection structure of a charging and discharging rack for battery packs of new energy vehicles includes a charging rack 3, a robotic arm 6 and a fire protection pool 4, wherein two rows of battery replacement batteries 1 with several layers in each row are stored on the charging rack 3, and the battery replacement batteries 1 are slidably connected to the slide rails 2 on the charging rack 3 through pulleys, and a driving mechanism 5 is installed on the top of the charging rack 3 between the two rows of battery replacement batteries 1, and the driving mechanism 5 is connected to the robotic arm 6, and the lower end of the robotic arm 6 is connected to the battery grasping mechanism 7, and a fire protection pool 4 is opened on the ground below the robotic arm 6.

[0013] According to the above structure, during operation, the battery grabbing mechanism 7 driven by the robot arm 6 can remove or put back the battery 1 on the charging rack 3. Once a battery smokes or a fire hazard occurs, the battery grabbing mechanism 7 driven by the robot arm 6 can promptly put the battery 1 into the fire pool 4, away from other normal battery 1, effectively reducing the scale of the fire.

[0014] The fire pool 4 can accommodate multiple battery-swap batteries 1 and submerge them, and can be equipped with a fire-fighting liquid circulation and filtration device, or can be externally connected to a fire hydrant, a fire-fighting water system, etc.

[0015] The top of the fire pool 4 can also be preferably slidably connected with a fireproof sealing upper cover. After the battery enters, the upper cover can be closed to prevent water vapor from overflowing.

[0016] The fire-resistant sealed upper cover may also be preferably provided with a smoke exhaust pipe, so that the smoke generated by the accident battery can be extracted and discharged to a safe area through the pipe.

[0017] When a battery fire accident occurs, it is preferred to cut off the electrical connections of other batteries as a whole to prevent the accident from escalating into a cascading fire.

[0018] All the components mentioned above are prior art, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0019] The above is only a preferred embodiment of the present invention.
