[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 4, in the embodiment of the present utility model, a temperature safety detection device for a new energy vehicle battery pack includes a water tank 1. Above the water tank 1, there is a table board 2 adapted to it. On the top surface of the table board 2, guide rods 3 are symmetrically and fixedly connected. At the top ends of the guide rods 3, a top board 4 is fixedly connected. At the top of the water tank 1, a mounting bracket 5 is fixedly connected. There is a plug-in connection structure between the mounting bracket 5 and the top board 4. On the top surface of the top board 4, a suspension rope 6 is fixedly connected. One end of the suspension rope 6 is fixedly connected to the mounting bracket 5. A new energy vehicle battery pack 7 is placed on the table board 2. Above the table board 2, there is a cover 8 adapted to it. Inside the table board 2 corresponding to the cover 8, ventilation holes 9 are opened. The ventilation holes 9 are corresponding to the gap between the new energy vehicle battery pack 7 and the cover 8 to prevent the ventilation holes 9 from being blocked by the new energy vehicle battery pack 7, affecting ventilation. A connecting pipe 10 is fixedly connected through the top board 4. An exhaust pipe 11 is fixedly connected through the mounting bracket 5. The exhaust pipe 11 is connected to the external space of the working area through a pipe. The exhaust pipe 11 is connected to the connecting pipe 10 through a first telescopic bellows. A fan 12 is fixedly installed inside the connecting pipe 10. The connecting pipe 10 is fixedly connected and communicated with the cover 8 through a second telescopic bellows. On both sides of the cover 8, guide sleeves 16 are symmetrically and fixedly connected. The guide sleeves 16 are slidably connected to the outside of the guide rods 3. On the top surface of the top board 4, first electric push rods 17 are symmetrically and fixedly connected. The telescopic ends of the first electric push rods 17 penetrate through the top board 4 and are fixedly connected to the cover 8.

[0023] During detection, the cover 8 is driven to fall by the first electric push rod 17, so that the battery for temperature safety monitoring can be isolated, achieving the effect of safety protection. At the same time, when the battery loses temperature and catches fire, the connection of the plug-in connection structure can be released, causing the table board 2 to fall into the water tank 1 and be suspended by the suspension rope 6, so that the battery drops into the water, which can be further isolated. At the same time, the heat of combustion can be dissipated through the evaporation of the water body and output through the pipe, reducing the impact on the surrounding environment of the workbench.

[0024] Inside the top of the cover 8, temperature sensors 13 are symmetrically and fixedly installed. On the inner walls of the four sides of the cover 8, heating plates 14 are fixedly connected. On the front outer wall of the cover 8, a temperature controller 15 is fixedly installed.

[0025] On the table board 2, outside the new energy vehicle battery pack 7, mounting seats 18 are symmetrically and fixedly connected. On the mounting seats 18, threaded turning handles 19 are threadedly connected. On the mounting seats 18, threaded holes for the threaded connection of the threaded turning handles 19 are opened. The end of the threaded turning handle 19 is rotatably connected to a clamping plate 20. The clamping plate 20 is slidably attached to the table board 2.

[0026] By turning the threaded turning handle 19, the clamping plate 20 approaches the new energy battery pack 7, thus achieving the effect of clamping and fixing.

[0027] One side of the top of the water tank 1 is provided with a water inlet pipe 21, and the other side of the bottom of the water tank 1 is provided with a water outlet pipe 22. The water inlet pipe 21 is connected to an external water supply pipeline, and the drain pipe 22 is connected to an external drainage pipeline. Valves are provided at the joints of the water inlet pipe 21 and the drain pipe 21 with the external water supply pipeline and the external drainage pipeline respectively.

[0028] Water can be replenished into the water tank 1 through the water inlet pipe 21, and the water liquid in the water tank 1 can be discharged through the water outlet pipe 22. At the same time, when the water in the water tank 1 is heated by the burning battery, the water liquid can be replaced, and the water can be replenished and drained quickly, achieving a cooling effect.

[0029] The plug-in connection structure includes a plug-in sleeve 23 and a plug-in rod 24. The plug-in sleeve 23 is fixedly connected to the inner side of the bottom of the mounting frame 5, and the plug-in rod 24 is fixedly connected to the top surface of the top plate 4. The plug-in rod 24 is inserted into the plug-in sleeve 23 and is slidably connected to the plug-in sleeve 23.

[0030] A U-shaped frame 25 is fixedly installed on the plug-in sleeve 23. A second electric push rod 26 is fixedly installed inside the U-shaped frame 25. The telescopic end of the second electric push rod 26 is fixedly connected to a bolt 27. The bolt 27 is simultaneously slidably inserted into the plug-in sleeve 23 and the plug-in rod 24. A limiting hole 28 for the bolt 27 to insert is provided on the plug-in rod 24, and a through hole for the bolt 27 to penetrate and slide is provided on the plug-in sleeve 23.

[0031] By inserting the plug-in sleeve 23 and the plug-in rod 24, and further forming a limit through the cooperation of the bolt 27 and the limiting hole 28, the top plate 4 is connected to the mounting frame 5. At the same time, it can be driven by the second electric push rod 26, so that when the battery catches fire, the fixation can be quickly released, and the battery can fall into the water tank 1.

[0032] The fan 12, the heating plate 14, the temperature controller 15, the first electric push rod 17, and the second electric push rod 26 are all externally connected to a power supply and a switch. The heating plate 14 and the temperature sensor 13 are electrically connected to the temperature controller 15.

[0033] The working principle of the present utility model is:

[0034] During use, place the battery to be tested on the platen 2. At this time, the threaded turning handle 19 can be rotated. With the cooperation of the threaded hole on the mounting seat 18, the clamping plate 20 approaches the new energy vehicle battery pack 7, thereby forming a clamping and fixing effect. At this time, start the first electric push rod 17, so that the cover 8 drops along the guide rod 3 through the guide sleeve 16, thereby isolating the new energy vehicle battery pack 7. At this time, a battery temperature test can be carried out. When the battery has a loss of temperature and catches fire, start the second electric push rod 26 to contract, so that the plug pin 27 disengages from the limit hole 28, thereby enabling the plugging rod 24 to disengage from the plugging sleeve 23, causing the platen 2 to drop into the hot water tank 1 until the suspension rope 6 suspends the top plate 4. At this time, the water liquid enters above the platen 2 through the ventilation holes 9. At this time, the new energy vehicle battery pack 7 is immersed in the water liquid, so that the heat generated by the combustion is absorbed by the water liquid to generate a large amount of steam, which is discharged through the connecting pipe 10 and the exhaust pipe 11. When the steam is discharged, it can be accelerated by the fan 12, thereby avoiding the serious impact of the high temperature of the combustion on the surrounding environment and reducing the surrounding heat radiation.

[0035] During the test, the new energy vehicle battery pack 7 itself continues to work and naturally generates heat. Further, temperature monitoring is carried out through the temperature sensor 13 and the temperature controller 15, which can detect the stable condition of the battery when working at high temperature. At the same time, auxiliary heating can be carried out through the heating plate 14 to directly increase the external environment temperature of the new energy vehicle battery pack 7, quickly realizing the safety detection of the battery operation in a high temperature environment.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
