[0020] See also Figure 1 , the present invention provides an explosion-proof laboratory 100 for automotive power batteries, including a laboratory body 1, a pressure reduction and noise reduction structure 2, a fire protection system 3, a sewage treatment system 4 and a monitoring system 5;

[0021] The laboratory body 1 is composed of reinforced concrete or steel plates. The internal space of the laboratory body 1 is used to place experimental samples and is provided with an explosion-proof door 6 and a pressure relief door 7. The explosion-proof door 6 and the pressure relief door 7 are respectively located on the two opposite sides of the laboratory body 1. The pressure reduction and noise reduction structure 2 is arranged on the side of the pressure relief door 7 away from the explosion-proof door 6, and is composed of a physical body with pressure reduction and noise reduction. The fire protection system 3 is installed on the top of the laboratory body 1, the sewage treatment system 4 is arranged outside the laboratory body 1, and the monitoring system 5 is installed above the concrete wall.

[0022] For further information, see Figure 1 The decompression and noise reduction structure 2 includes a decompression chamber 21, which is fixedly connected to the laboratory body 1, and is communicated with the interior of the laboratory body 1, and is located on one side of the laboratory body 1 close to the pressure relief door 7.

[0023] For further information, see Figure 1 The decompression chamber 21 has a decompression and noise reduction air inlet 211 and a decompression and noise reduction air outlet 212. The decompression and noise reduction air inlet 211 is located on a side of the decompression chamber 21 close to the pressure relief door 7, and is connected to the interior of the laboratory main body 1; the decompression and noise reduction air outlet 212 is located on a side of the decompression chamber 21 away from the decompression and noise reduction air inlet 211, and is connected to the decompression and noise reduction air inlet 211.

[0024] For further information, see Figure 1The decompression chamber 21 also has a gas expansion chamber 213, which is located between the decompression and noise reduction air inlet 211 and the decompression and noise reduction air outlet 212; the decompression and noise reduction structure 2 also includes a gas expansion tube 22, which is fixedly connected to the decompression chamber 21 and communicates with the gas expansion chamber 213.

[0025] In this embodiment, the laboratory body 1 is composed of reinforced concrete or steel plates in a certain configuration, and the space inside is used to place experimental samples, and is provided with an explosion-proof door 6 and a pressure relief door 7; the pressure reduction and noise reduction structure 2 is arranged behind the pressure relief door 7, and is composed of a physical body with pressure reduction and noise reduction; the fire protection system 3 is installed on the top of the laboratory; the sewage treatment system 4 is arranged outside the laboratory; the monitoring system 5 is installed at an appropriate position above the concrete wall; if the laboratory body 1 is composed of reinforced concrete, the thickness is 50 cm, and if it is composed of steel plates, the thickness is 10 cm, so that it has sufficient strength to resist the shock wave generated by the explosion; the pressure reduction and noise reduction structure 2 is mainly composed of the pressure reduction and noise reduction air inlet 211, the pressure reduction and noise reduction air outlet 212, and the gas expansion chamber 213 (two-stage ), the gas expansion tube 22 (2 pieces), the gas expansion tube 22 is provided with a plurality of gas outlets around the tube body to discharge the high-pressure gas into the expansion chamber, and a channel is provided between the two-stage expansion chambers, which is generally directly connected to the front expansion tube, and the channel diameter is smaller than the expansion tube diameter, so that part of the gas directly enters the rear-stage expansion chamber and rubs with the gas entering the chamber through the front-stage expansion chamber and the rear-stage expansion tube, thereby reducing the flow rate and pressure. In this way, by setting the pressure relief door 7 and the pressure relief channel, the indoor pressure drops rapidly during the explosion, and the pressure reduction and noise reduction structure 2 is set, so that the shock wave pressure generated during the explosion drops in the channel of the structure, which greatly reduces the damage to the outside world, and greatly reduces the noise, reduces noise pollution, and thus improves the safety performance and environmental protection performance of the explosion-proof laboratory during the battery explosion process.

[0026] For further information, see Figure 1 The fire protection system 3 includes a smoke alarm 31, an automatic sprinkler valve 32 and a fire water pipe 33. The fire water pipe 33 is fixedly installed in the laboratory body 1 and is connected to an external fire water supply equipment; the automatic sprinkler valve 32 is arranged on the fire water pipe 33, and controls the fire water pipe 33 to spray water according to a set threshold; the smoke alarm 31 is arranged on the fire water pipe 33, is located in the laboratory body 1, and is electrically connected to the automatic sprinkler valve 32.

[0027] For further information, see Figure 1The sewage treatment system 4 includes a sewage collection tank 41 and a sewage treatment tank 42. The sewage collection tank 41 is fixedly connected to the laboratory main body 1 and is located below the automatic spray valve 32; the sewage treatment tank 42 is connected to the sewage collection tank through a pipeline and is connected to the interior of the sewage collection tank.

[0028] For further information, see Figure 1 The monitoring system 5 includes a first camera 51 and a second camera 52. The first camera 51 is fixedly connected to the laboratory body 1 and is located inside the laboratory body 1; the second camera 52 is fixedly connected to the laboratory body 1 and is located inside the laboratory body 1, and is located on a side of the laboratory body 1 away from the first camera 51.

[0029] In this embodiment, the fire protection system 3 is composed of the smoke sensor, the automatic sprinkler and the fire hose 33. According to the set threshold, the sprinkler sprays water to extinguish the fire when necessary. The sewage treatment system 4 is composed of the sewage collection tank 41 and the sewage treatment pool 42. The sewage sprayed by the automatic fire extinguishing is collected and treated. The monitoring system 5 is composed of the first camera 51, the second camera 52 and the transmission line, which is used to monitor the indoor test conditions. When conducting an abuse test, the monitoring system 5 monitors the test conditions in real time. If a fire occurs, the water spraying is started to extinguish the fire. If an explosion occurs and the shock wave is relatively large, the pressure relief door 7 is opened to relieve the pressure in the room. The toxic and harmful exhaust gas generated by the combustion and explosion is treated by the purification system and discharged into gases that meet the national environmental protection standards. The sewage generated by the fire extinguishing can be collected and treated by the sewage treatment system 4 into water that meets the national emission standards.

[0030] For further information, see Figure 1 The opening direction of the explosion-proof door 6 is toward the interior of the laboratory body 1 ; the opening direction of the pressure relief door 7 is toward the direction away from the laboratory body 1 .

[0031] In this embodiment, the explosion-proof door 6 is composed of a 10 cm steel plate and is opened inside first to prevent the high-pressure gas from the explosion from breaking the door bolt and causing the door to be opened outward and hit people and objects outside; the pressure relief door 7 is composed of a color steel plate. When an explosion occurs indoors, the high-pressure gas breaks through the color steel plate and leaks outward.

Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
