Description

Technical Field

A control box is fixed on the left side of the box, and the control box is electrically connected to the air pressure sensor, explosion-proof pressure relief port, exhaust fan, and louver fan. The wire harness tubes can organize and protect the wires and data cables inside the experimental cabin to prevent the connecting lines from being damaged in a fire, while also reducing the risk of fire caused by a short circuit in the wires, thereby improving the safety of the experimental cabin.

[0007] Preferably, an installation frame is fixed on the left side of the box body, and a protective door is rotatably connected to the inner wall of the installation frame through a hinge. A sealing strip is fixed to the inner wall of the installation frame. When the protective door is closed, the interior of the box body will be in a closed state, thereby preventing gas leakage.

[0008] Preferably, an observation window is fixed on the left side of the box body, and a first fire-resistant glass is fixed on the inner wall of the observation window.

[0009] Preferably, a fixing frame is fixed to the front side of the box body, and a second fire-resistant glass is fixed to the inner wall of the fixing frame. The second fire-resistant glass can withstand high temperature and flames to protect observers from the effects of fire, while ensuring that the fixing frame will not break during the experiment, thereby maintaining the integrity and safety of the experimental cabin.

[0010] Preferably, a plurality of support blocks are fixed to the bottom surface of the box, and the support blocks can raise the distance between the box and the ground to prevent corrosion of the bottom surface of the box caused by moisture on the ground, thereby extending the service life of the box and further improving the safety of the experimental process.

[0011] Compared with the prior art, a battery fire simulation test chamber adopting the above technical solution has the following beneficial effects:

[0012] 1. Through the cooperation of explosion-proof pressure relief port and air pressure sensor, the pressure change inside the box can be monitored in real time, so that the pressure can be released when the pressure inside the experimental cabin is too high, to prevent the occurrence of explosion accidents, and protect the structural integrity of the experimental cabin and the safety of the experimenters. Through the cooperation of exhaust fan and shutter fan, the smoke and harmful gases in the experimental cabin can be discharged after the experiment or when necessary, to keep the internal environment of the experimental cabin clean and prepare for the next experiment. The sprayed foam fire extinguishing agent can be discharged through the drain pipe;

[0013] Second, the sealing strip can ensure the tight closure between the protective door and the installation frame, preventing flames, smoke and harmful gases from leaking to the outside of the experimental chamber, thereby protecting the safety of the experimenters and preventing the external environment from affecting the experimental results;

[0014] 3. Through the cooperation of the observation window and the first fire-resistant glass, the staff can observe the experimental process intuitively without direct contact with the fire source, so that the staff can record the experimental data more intuitively, make the experimental data comparative, and ensure the accuracy of the data.
