Description

Technical Field

[0001] This utility model relates to the field of battery explosion-proof testing technology, and in particular to a new energy battery explosion-proof performance testing machine. Background Technology

[0002] New energy batteries are a new type of energy storage device that can convert renewable energy sources such as solar, wind, and hydropower into chemical energy for storage. Common new energy batteries on the market mainly include ternary lithium batteries, lithium iron phosphate batteries, lithium cobalt oxide batteries, and lead-acid batteries.

[0003] Before the battery leaves the factory after it is manufactured, it needs to undergo an explosion-proof performance test to prevent the battery from burning or exploding due to electrical sparks during charging.

[0004] For example, in the prior art, the patent with authorization announcement number CN212341397U discloses a battery explosion-proof performance testing system. This battery explosion-proof performance testing system has the advantages of simple structure, quick assembly and disassembly, low requirements for sample processing, high reliability, strong stability, easy functional expansion, convenient maintenance and repair, and easy manufacturing. It is suitable for battery explosion-proof performance testing.

[0005] However, during the battery testing process, the smoke generated by the battery combustion is directly discharged through the blower, which not only pollutes the environment, but also, when the door is closed, the simple setting of the blower results in poor smoke flow inside the chamber, affecting the smoke exhaust effect. Therefore, a new energy battery explosion-proof performance testing machine was designed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a new energy battery explosion-proof performance testing machine.

[0007] The technical problem to be solved by this utility model is to provide a new energy battery explosion-proof performance testing machine, which solves the problem that in the existing explosion-proof performance testing machine, fumes are directly discharged during the explosion-proof testing of batteries, causing environmental pollution.

[0008] This utility model provides a new energy battery explosion-proof performance testing machine, including an explosion-proof enclosure, an explosion-proof door, an explosion-proof glass window, a smoke removal component, and a door locking component. The explosion-proof door is rotatably mounted on the left side of the outer surface of the explosion-proof enclosure via a hinge. An explosion-proof glass window is embedded in the center of the explosion-proof door. A smoke removal component is fixedly mounted on the back of the explosion-proof door. A door locking component is fixedly mounted on the right side of the explosion-proof enclosure. A baffle is fixedly mounted on the outer end of the inner side of the explosion-proof enclosure. Guide rods are fixedly mounted on both the left and right sides of the interior of the explosion-proof enclosure. A lifting plate is threaded through the two guide rods. Discharge heads are installed on both the left and right sides of the bottom surface of the lifting plate. A lead screw is rotatably mounted on the center of the lifting plate via a bearing. The lead screw is threadedly connected to the upper surface of the explosion-proof enclosure. A turntable is fixedly mounted on the top of the lead screw. The two discharge heads are electrically connected to an external power source.

[0009] Preferably, the smoke removal assembly includes an activated carbon box, a fan, an air inlet pipe, and a return pipe. The fan is installed through the center of the upper surface of the activated carbon box, the air inlet pipe is installed at the air inlet end of the fan, and the return pipe is installed through the bottom of the activated carbon box.

[0010] Preferably, the air inlet pipe extends through the upper surface of the explosion-proof enclosure, and the return pipe extends through the bottom inner side of the explosion-proof enclosure.

[0011] Preferably, the door locking assembly includes a fixing plate, an embedded groove, a trapezoidal block, a through rod, a spring, and a vertical plate. The fixing plate is fixedly disposed on the right side surface of the explosion-proof enclosure. Multiple embedded grooves are provided on the left side surface of the fixing plate. A trapezoidal block is fixedly disposed in the embedded groove by a spring. A through rod is fixedly disposed at the right end of the trapezoidal block. A vertical plate is fixedly disposed at the right end of the through rod.

[0012] Preferably, the gap between the trapezoidal block and the explosion-proof enclosure is equal to the thickness of the explosion-proof enclosure door.

[0013] Preferably, when the spring is in its naturally extended state, the outer side of the trapezoidal block is completely embedded in the embedding groove, and the inner side of the trapezoidal block extends out of the embedding groove. When the spring is in its maximum compressed state, the trapezoidal block is completely embedded in the embedding groove.

[0014] Preferably, a fire extinguisher is installed on the top inner side of the explosion-proof enclosure, and a smoke sensor is installed on the fire extinguisher. The smoke sensor is electrically connected to the switch of the fire extinguisher through a controller.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] 1. This utility model is equipped with a smoke removal component. When the battery explodes and catches fire during testing, the fan is turned on and draws the smoke into the activated carbon box through the air inlet pipe. The activated carbon in the activated carbon box adsorbs the smoke, and the adsorbed air flows back into the explosion-proof box through the return pipe, ensuring air circulation in the explosion-proof box and ensuring the smoke removal effect.

[0017] 2. This utility model features a door locking assembly. When the explosion-proof box door is closed, it presses against the trapezoidal block on the fixed plate, causing the trapezoidal block to be fully embedded in the recessed groove. The spring is compressed. When the explosion-proof box door is against the explosion-proof box body, the trapezoidal block pops out of the recessed groove under the spring force, achieving the locking effect of the explosion-proof box door. To open the explosion-proof box door, simply pull the vertical plate to the right to insert the trapezoidal block into the recessed groove. The operation is simple and convenient.

[0018] 3. This utility model is equipped with a fire extinguisher. When a deflagration fire occurs during a battery pressure test, the smoke sensor detects the smoke and controls the fire extinguisher to activate via the controller, thereby extinguishing the fire on the burning battery.

Detailed Implementation

[0028] Example:

[0029] like Figures 1-6 As shown, an embodiment of this utility model provides a new energy battery explosion-proof performance testing machine, including an explosion-proof enclosure 1, an explosion-proof door 2, an explosion-proof glass window 201, a smoke removal component, and a door locking component. The explosion-proof door 2 is rotatably mounted on the left side of the outer surface of the explosion-proof enclosure 1 via a hinge. The explosion-proof glass window 201 is embedded in the center of the explosion-proof door 2. The smoke removal component is fixedly mounted on the back of the explosion-proof door 2. The door locking component is fixedly mounted on the right side of the explosion-proof enclosure 1. A baffle 101 is fixedly mounted on the outer end of the inner side of the explosion-proof enclosure 1. Guide rods 5 are fixedly mounted on both the left and right sides of the interior of the explosion-proof enclosure 1. A lifting plate 6 is threaded through the two guide rods 5. Discharge heads 7 are installed on both the left and right sides of the bottom surface of the lifting plate 6. A lead screw 8 is rotatably mounted on the center of the lifting plate 6 via a bearing. The lead screw 8 is threadedly connected to the upper surface of the explosion-proof enclosure 1. A turntable 9 is fixedly mounted on the top of the lead screw 8. The two discharge heads 7 are electrically connected to an external power source.

[0030] In actual use, when conducting explosion-proof tests on batteries, the fuse is fixed below the discharge head 7, the battery to be tested is placed inside the explosion-proof enclosure 1, the explosion-proof enclosure door 2 is closed, and the door is locked using the door locking assembly. The turntable 9 rotates the lead screw 8, which drives the lifting plate 6 to move downward, so that the fuse is above the battery. The power supply to the discharge head 7 is then turned on, the fuse melts and generates an electric spark, thus achieving the effect of explosion-proof testing of the battery.

[0031] In this embodiment, the smoke removal assembly includes an activated carbon box 3, a fan 301, an air inlet pipe 302, and a return pipe 303. The fan 301 is installed through the center of the upper surface of the activated carbon box 3, the air inlet pipe 302 is installed at the air inlet end of the fan 301, and the return pipe 303 is installed through the bottom of the activated carbon box 3.

[0032] In this embodiment, the air inlet pipe 302 passes through the upper surface of the explosion-proof enclosure 1, and the return pipe 303 passes through the bottom inner side of the explosion-proof enclosure 1.

[0033] By incorporating a smoke removal component, when the battery explodes and catches fire during testing, the fan 301 is activated. The fan 301 draws the smoke into the activated carbon box 3 through the air inlet pipe 302. The activated carbon in the activated carbon box 3 adsorbs the smoke, and the adsorbed air flows back to the explosion-proof enclosure 1 through the return pipe 303, ensuring air circulation within the explosion-proof enclosure 1 and guaranteeing the smoke removal effect.

[0034] In this embodiment, the door locking assembly includes a fixing plate 4, an embedding groove 401, a trapezoidal block 402, a through rod 403, a spring 404, and a vertical plate 405. The fixing plate 4 is fixedly installed on the right side surface of the explosion-proof enclosure 1. Multiple embedding grooves 401 are provided on the left side surface of the fixing plate 4. A trapezoidal block 402 is fixedly installed in the embedding groove 401 by a spring 404. A through rod 403 is fixedly installed at the right end of the trapezoidal block 402. A vertical plate 405 is fixedly installed at the right end of the through rod 403.

[0035] In this embodiment, the gap between the trapezoidal block 402 and the explosion-proof enclosure 1 is equal to the thickness of the explosion-proof enclosure door 2, which facilitates the positioning of the explosion-proof enclosure door 2 by the trapezoidal block 402.

[0036] In this embodiment, when the spring 404 is in its naturally extended state, the outer side of the trapezoidal block 402 is completely embedded in the embedding groove 401, and the inner side of the trapezoidal block 402 extends out of the embedding groove 401. When the spring 404 is in its maximum compressed state, the trapezoidal block 402 is completely embedded in the embedding groove 401, and the trapezoidal block 402 will not affect the closing of the explosion-proof door 2.

[0037] With the door locking assembly in place, when the explosion-proof door 2 is closed, it presses against the trapezoidal block 402 on the fixed plate 4, causing the trapezoidal block 402 to be fully embedded in the recess 401. The spring 404 is in a compressed state. When the explosion-proof door 2 is attached to the explosion-proof enclosure 1, the trapezoidal block 402 is ejected from the recess 401 under the elastic force of the spring 404, thus locking the explosion-proof door 2. To open the explosion-proof door 2, simply pull the vertical plate 405 to the right to insert the trapezoidal block 402 into the recess 401. The operation is simple and convenient.

[0038] In this embodiment, a fire extinguisher is installed on the top inner side of the explosion-proof enclosure 1, and a smoke sensor is installed on the fire extinguisher. The smoke sensor is electrically connected to the switch of the fire extinguisher through a controller.

[0039] By installing a fire extinguisher, when a deflagration fire occurs during a battery pressure test, the smoke sensor detects the smoke and the controller activates the fire extinguisher to extinguish the fire on the burning battery.

[0040] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
