Description

Technical Field

[0001] The invention relates to the technical field of explosion-proof power supplies, in particular to an explosion-proof lithium battery. Background Art

[0002] Explosion-proof lithium batteries are designed for environments with high safety requirements. They not only have all the functions of ordinary lithium batteries, but also have enhanced safety features. This type of battery is particularly suitable for situations where explosive gases may exist, such as in industrial fields such as drilling and mining. In these environments, explosion-proof lithium batteries used in mining lamps are usually hung around the waists of workers to provide a stable power supply for headlamps.

[0003] The explosion-proof lithium batteries used in mining lamps are usually equipped with an explosion-proof valve mechanism. The core function of this mechanism is that when the internal pressure of the battery rises abnormally, it can automatically open and quickly release the gas accumulated inside, thereby effectively preventing the battery from exploding. However, when the explosion-proof valve is opened due to internal abnormalities in the battery, there is often a lack of direct user prompts, which leads to insufficient control of the user's safety status and difficulty in timely detection of potential safety risks. Therefore, based on the above problems, an explosion-proof lithium battery is proposed. Summary of the invention

A guide rod 33 is fixedly connected to the upper side of the partition 31. A connecting strip 34 is slidably connected to the outer side of the guide rod 33. Both ends of the connecting strip 34 are fixedly connected to a block 35 on the inner side of the through opening 32. A folding block 36 is fixedly connected to the upper side of the block 35. The upper ends of the folding blocks 36 are fixedly connected to a sealing plate 37 on the inner side of the groove of the guide rail 18. A derivation block 38 is fixedly connected to the upper side of the connecting strip 34. A prompting part 4 is installed on the upper side of the derivation block 38. A mounting hole 19 is provided in the rear shell plate of the shell 11. The prompting part 4 includes a guide tube 41 fixed to the inner side of the mounting hole 19. The inner side of the guide tube 41 slides The prompting part 4 is dynamically connected with a prompting rod 42, the front end of the prompting rod 42 is fixedly connected with a limited block 43, the outer side of the prompting rod 42 is sleeved with a spring 44, and the spring 44 is between the limit block 43 and the guide tube 41, and the front side of the limit block 43 is fixedly connected with a conduction frame 45 sleeved on the outer side of the guide rod 33, so that the prompting part 4 can be moved by conduction, thereby prompting the user; the battery body 2 is between a group of abutments 15, the battery body 2 is between the rubber support block 14 and the positioning frame 16, and the inner wall of the positioning frame 16 is in contact with the outer end surface of the battery body 2. Through this arrangement, the battery body 2 can be positioned in the protective shell 1, and a wiring is provided on the right side of the battery body 2, so that the battery body 2 can supply power to the miner's lamp through the wiring The wiring of the battery body 2 passes through the side hole of the shell 11, and the wiring of the battery body 2 is tightly fitted with the side hole of the shell 11. This arrangement prevents leakage of the protective shell 1; the front side of the shell 11 is detachably connected with the cover body 12 by bolts. This arrangement allows the user to open the protective shell 1 and inspect the inside. The rear side of the shell 11 is provided with an elastic plastic hanging plate. This arrangement facilitates the user to hang the protective shell 1 on the belt. The sealing plate 37 is between the exhaust block 17 and the guide rail 18. This arrangement allows the sealing plate 37 to seal the exhaust block 17. There is a gap between the sealing plate 37, the folding block 36 and the upper inner wall of the shell 11. This arrangement allows the sealing plate 37 and the folding block 36 to move upward;The diameter of the prompt rod 42 is the same as the inner diameter of the conduit 41. The outer curved surface of the prompt rod 42 fits with the inner wall of the conduit 41. This setting enables the conduit 41 to smoothly guide the prompt rod 42 and prevent gas from leaking from the conduit 41. The rear end of the prompt rod 42 is a round head setting. This setting prevents the prompt rod 42 from squeezing the user and causing no harm to the user. The guide rod 33 is a square rod structure. The inner wall of the conduction frame 45 fits with the outer end surface of the guide rod 33. This setting enables the guide rod 33 to guide the displacement of the conduction frame 45 and prevent the displaced conduction frame 45 from rotating. The upper inclined surface of the derivation block 38 fits with the lower inclined surface of the conduction frame 45. This setting enables the pressure applied by the derivation block 38 to the conduction frame 45 to cause the conduction frame 45 to move backward. ;

[0028] like Figure 3-Figure 4 , Figure 8-Figure 9 As shown, the collecting part 5 includes a busbar 51 located at the lower side of the battery body 2, and the lower sides of the busbar 51 are fixedly connected with support blocks 52, and the inner sides of the support blocks 52 are provided with through holes 53 that penetrate the busbar 51, and the rubber support blocks 14 are located on the inner sides of the through holes 53. The linkage part 6 includes two middle connecting strips 62 located at the lower side of the battery body 2, and the left and right ends of the middle connecting strips 62 are fixedly connected with angle brackets 61, and the side of the angle brackets 61 away from the battery body 2 is fixedly connected with symmetrically arranged protrusions 63 The outer side of the guide rod 33 is slidably connected with a pressure plate 64, and the front side of the pressure plate 64 is fixedly connected with a pressure guide block 67. Pressure rods 66 are arranged in the left and right grooves of the pressure plate 64. The lower sides of both ends of the pressure rod 66 are fixedly connected with connecting rods 65. The lower ends of the connecting rods 65 pass through the partition 31 and are fixedly connected with the upper end surface of the protrusion 63, so that the battery body 2 leaks electrolyte due to abnormality, and the leaked electrolyte drips into the busbar 51, quickly corroding the rubber support block 14, causing it to lose its supporting ability, and the battery body 2 moves down accordingly. The downward movement causes the angle bracket 61, the middle connecting strip 62 and the protrusion 63 to move downward together, thereby driving the connecting rod 65 and the pressure rod 66 to move downward. The pressure rod 66 acts on the pressure plate 64 and the pressure guide block 67 to press them downward. The downward pressure of the pressure guide block 67 exerts pressure on the conduction frame 45, pushing the limit block 43 and the prompt rod 42 to move backward. Finally, the prompt rod 42 exposes the conduit 41, squeezes the user's lower back, and reminds the user of battery abnormality; the rubber support block 14 is a natural rubber block structure. Since natural rubber has relatively weak chemical resistance, the electrolyte can be quickly The rubber support block 14 is corroded quickly, and a distance is set between the busbar 51 and the battery body 2. Through this setting, after the rubber support block 14 is corroded, the battery body 2 can be moved downward. The pressure plate 64 is set on the upper side of the conduction frame 45, and a distance is set between the pressure plate 64 and the conduction frame 45. Through this setting, the pressure plate 64 can be moved downward. The pressure guide block 67 is set on the upper side of the conduction frame 45, and an inclined surface is set on the lower side of the pressure guide block 67. Through this setting, the downward movement of the pressure guide block 67 can push the conduction frame 45.

[0029] Working process: The safety warning operation of the explosion-proof lithium battery is as follows: the battery body 2 is connected to the miner's lamp through wiring to power the miner's lamp, and the explosion-proof lithium battery is hung on the belt through the elastic plastic hanging plate on the rear side of the shell 11, so that the explosion-proof lithium battery is at the user's lower back; pressure relief prompt operation: when the battery body 2 is abnormal, a large amount of gas will quickly accumulate under the partition 31, causing the internal pressure to increase. As the air pressure increases, the block 35 will be pushed upward, thereby breaking away from the through port 32, so that the gas below the partition 31 can flow through the through port 32 to the top of the partition 31. In this process, the upward movement of the block 35 will drive the folding The block 36 and the sealing plate 37 move, and the sealing plate 37 moves upward along the guide rail 18 to stop sealing the exhaust block 17, so that the gas on the upper side of the partition 31 can be discharged through the exhaust block 17, completing the pressure relief operation. At the same time, the upward movement of the blocking block 35 will also drive the connecting strip 34 and the derivation block 38 to move upward. The upward movement of the derivation block 38 will exert pressure on the conduction frame 45 to move it backward, thereby pushing the limit block 43 and the prompt rod 42 to move backward, which causes the rear end of the prompt rod 42 to be exposed from the conduit 41, squeezing the user's lower back, thereby reminding the user that the battery body 2 has an abnormality. The pressure relief prompt operation is completed through the above steps, and the explosion-proof lithium battery is realized. When the battery is abnormal and the pressure is safely released, a prompt can be issued to the user in time, so that the user can quickly perceive the potential safety risks and take corresponding countermeasures; Leakage prompt operation: When the battery body 2 causes electrolyte leakage due to an abnormality, the leaked electrolyte will drip into the busbar 51. In the busbar 51, the electrolyte will quickly corrode the rubber support block 14 passing through it, causing its shape to change and it will no longer be able to effectively support the battery body 2. As the rubber support block 14 is damaged, the battery body 2 will move downward, thereby driving the corner support 61, the middle connecting strip 62 and the protrusion 63 to move downward together. This chain reaction will cause the connecting rod 65 and the pressure rod on both sides to move downward. 66 also moves downward, and the downward movement of the pressure rod 66 acts on the pressure plate 64 and the pressure guide block 67 to press them downward. The downward pressure of the pressure guide block 67 applies pressure to the conduction frame 45, prompting it to move backward, thereby pushing the limit block 43 and the prompt rod 42 to move backward. Finally, the rear end of the prompt rod 42 is exposed from the guide tube 41, squeezing the user's lower back, thereby reminding the user that the battery body 2 has an abnormality. Through this series of mechanical actions, the explosion-proof lithium battery can promptly issue a prompt to the user when an electrolyte leak occurs, ensuring that the user can quickly perceive and respond to potential safety risks, and avoiding fires and explosions caused by electrolyte leakage to cause harm to personnel and the environment.
