Description

Technical Field

[0001] The invention relates to the technical field of lithium battery modules, in particular to a lithium battery module for intelligent fire extinguishing with integrated sol-gel fire extinguishing agent. Background Art

[0002] Lithium battery modules are often used in new energy electric vehicles. The energy storage capacity of lithium batteries decreases in cold weather. Lithium batteries are easy to burn when exposed to air. The burning of a single lithium battery will cause other nearby lithium batteries to burn, causing economic losses and threatening people's lives.

[0003] The defects of existing lithium battery modules are: 1. The prior art KR1020110072274A discloses a lithium battery. This technology does not have the function of cooling down and extinguishing a single battery cell when the temperature of the single battery cell rises. When a single battery cell burns, it is easy to cause the adjacent battery cells to burn, causing greater economic losses and threatening people's lives. Therefore, a lithium battery module with an integrated sol-gel fire extinguishing agent that can extinguish and cool a single lithium battery cell to avoid affecting other batteries is needed to solve this problem.

[0004] 2. The prior art KR101306274B1 discloses a lithium battery. When the heat preservation structure of the battery cell is set, when the temperature of a single battery cell rises, the heat will affect other battery cells while the battery cell is dissipating the heat. Therefore, a lithium battery module with an integrated sol-gel fire extinguishing agent and intelligent fire extinguishing that can insulate the battery cell and reduce the impact of the temperature rise of a single battery cell on other battery cells is needed to solve this problem.

[0005] 3. The prior art KR101785267B1 discloses a lithium battery, which does not have a structure that is convenient for replacing damaged battery cells. When the battery cells need to be replaced, it is troublesome for people to take out the battery cells from the small space because the battery cells have a small movable space inside the shell. Therefore, a lithium battery module with an integrated sol-gel fire extinguishing agent and intelligent fire extinguishing that can increase the movable space of the battery cells and facilitate people to take out the battery cells is needed to solve this problem.

[0006] 4. The prior art CN110306885B discloses a lithium battery module. This technology does not have a structure for cleaning the bottom of the shell containing the lithium battery. When dust adheres to the bottom of the shell, it is easy to cause the heat dissipation performance of the battery module to decrease. Therefore, a lithium battery module with an integrated sol-gel fire extinguishing agent and intelligent fire extinguishing that can clean the dust at the bottom of the lithium battery module shell is needed to solve this problem. Summary of the invention

[0007] One purpose of the present application is to provide a lithium battery module with integrated sol-gel fire extinguishing agent for intelligent fire extinguishing, which can solve the technical problems raised in the prior art.

[0008] To achieve the above object, the present invention provides the following technical solutions: a lithium battery module with integrated sol-gel fire extinguishing agent intelligent fire extinguishing, comprising a frame body, a lithium battery explosion-proof shell and a support frame, a controller is installed on the front of the frame body, a plurality of heat-insulating rods are installed on the inner side of the frame body, a plurality of lithium battery units are arranged inside the frame body, and the lithium battery units are located above the heat-insulating rods; Cylinders are symmetrically mounted on both sides of the frame body 1, piston rods are mounted on output ends of the cylinders, connecting blocks are mounted on the outer sides of the piston rods, and supporting frames are mounted on the inner sides of the two connecting blocks.

[0020] 3. When the explosion-proof shell of the lithium battery needs to be replaced, the support frame is pushed backward by the cylinder to increase the activity space of the explosion-proof shell of the lithium battery, thereby making it convenient for people to take out the explosion-proof shell of the lithium battery from the frame body.

[0021] 4. The present invention can drive the scraper rod to rotate through the second motor to clean the dust at the bottom of the support frame, thereby preventing the heat dissipation performance of the support frame from being reduced due to dust coverage. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The method of using the lithium battery module with integrated sol-gel fire extinguishing agent intelligent fire extinguishing is as follows: S1.

When the lithium battery explosion-proof casing 12 needs to be replaced, the cylinder 24 pushes the support frame 28 to move backward, thereby making it convenient for people to take out the lithium battery explosion-proof casing 12 from the frame body 1.

[0033] S2 also includes the following steps: S21, the motor 2 30 drives the scraper rod 32 to rotate to scrape the dust off the bottom of the support frame 28.

[0034] Working principle: Before using the lithium battery module with integrated sol-gel fire extinguishing agent for intelligent fire extinguishing, you should first check whether there are any problems that affect the use of the lithium battery module with integrated sol-gel fire extinguishing agent for intelligent fire extinguishing. When the temperature of a certain part of the lithium battery core material 18 rises to a certain value, the inner PVC film 16 will be melted, and the sol-gel fire extinguishing agent coating 15 will be released at the melted part of the inner PVC film 16 to accurately cool the temperature-increasing part of the lithium battery compartment 17. When the infrared temperature sensor 16 detects that the temperature of a lithium battery explosion-proof housing 12 rises to a set value, the heat-conducting rod 9 moves left and right until the infrared temperature sensor 11 detects a temperature value that is consistent with the infrared temperature sensor 16. At the same time, the movement is stopped. At this time, the heat-conducting rod 9 moves to the bottom of the lithium battery explosion-proof shell 12 with increased temperature, and the thermally conductive silicone sheet 10 contacts the bottom of the lithium battery explosion-proof shell 12, so that the heat of the lithium battery explosion-proof shell 12 is transferred to the heat-conducting rod 9, and the heat-conducting rod 9 transfers the heat to the support frame 28, and then the support frame 28 dissipates the heat to the outside. At the same time, the motor 2 30 drives the scraper rod 32 to rotate to scrape the bottom of the support frame 28. When the lithium battery explosion-proof shell 12 needs to be replaced, the support frame 28 is pushed to move backward by the cylinder 24, so as to increase the activity space of the lithium battery explosion-proof shell 12, so that people can easily take out the lithium battery explosion-proof shell 12 from the frame body 1.
