Technical Field

[0001] This utility model belongs to the field of oil tank technology, and in particular to a safety status monitoring device for oil tanks in railway oil depots. Background Technology

[0002] With the steady development of my country's economy, railway freight volume continues to grow, leading to an increasing demand for oil energy and a gradual increase in the number and scale of oil depots. On the other hand, as my country's urbanization level continues to rise and cities expand, railway oil depots are increasingly surrounded by urban areas, resulting in denser populations around them. This makes the safe operation of oil depots increasingly important. Furthermore, the numerous oil tanks housed within these depots significantly impact their safety. Chinese Patent No. CN217101421U discloses "An oil tank monitoring device for an oil storage area, comprising an oil tank body; a first connecting block fixed to the top of the oil tank body; a second connecting block installed on the first connecting block; a first fixing plate fixed to the side end of the second connecting block; a first monitoring device fixed to the bottom end of the first fixing plate; and a second fixing plate fixed to the end of the second connecting block away from the first fixing plate." The bottom end of the second fixed plate is fixed with a second monitoring device. The first monitoring device can monitor the oil level inside the tank. If the level is too low or too high, the first monitoring device will activate an alarm to remind staff to handle the situation promptly. The second monitoring device can monitor the environment around the tank to detect whether there is oil leakage or damage to the tank. This is more efficient than traditional manual monitoring. Existing technology uses the first and second monitoring devices to monitor the liquid level inside the tank and the environment outside the tank, respectively. However, it does not have a further device to monitor the pressure inside the tank and the temperature at different heights. The monitoring is not comprehensive enough, resulting in a lack of safety.
