[0002] The oil storage tank can also be called a low-level tank. The oil storage tank is mainly used to store the heat transfer oil discharged from the high-level tank, furnace tubes and systems. It should be in a low liquid level state during operation and be ready to receive external heat transfer oil at any time. The exhaust port should be connected to a safe area and no valve should be installed. In order to accurately understand the amount of oil in the oil storage tank, the oil level gauge will be used to display the oil storage in the oil storage tank.

[0003] Most of the existing oil level gauge sensors are of the reed switch type, using fragile glass tubes. The pins need to be bent to produce tiny cracks in the glass tubes, which will cause leakage of internal inert gas and cause oxidation failure of the contacts.

[0004] Therefore, it is necessary to propose an oil storage tank oil storage amount display device to solve the above problems. Utility Model Content

[0007] Preferably, the sensor is fixedly connected to the bottom end of the oil storage tank via a flange, one end of the sensor is connected to a wire, and one end of the wire is connected to a display meter, and the display meter is used to display the liquid level.

[0008] Preferably, magnetic blocks are fixed on both sides of the oil storage tank, and the magnetic blocks and the magnetic balls in the airbag repel each other.

[0009] Preferably, the two magnetic blocks are distributed along the height direction of the oil storage tank, and the heights of the two magnetic blocks are consistent.

[0013] Technical effects and advantages of the utility model:

[0014] 1. In the actual operation of the utility model, the float can float on the oil, and the multiple air bags can increase the buoyancy of the float, so that the float always remains on the oil. Even if the buoyancy of the float itself is damaged, it can continue to be used. At the same time, the multiple air bags can increase the safety of the float. When the float hits the inner wall of the storage cavity, the multiple air bags and the hose can play a buffering role to avoid damage to the float caused by the impact.

[0015] 2. Furthermore, when the float approaches the inner wall of the oil tank as the oil shakes, the magnetic ball in the airbag will repel the magnetic block on the outside of the oil tank. The repulsive force generated can keep the float away from the inner wall of the oil tank to avoid collision, thereby increasing the safety of the float and the protection effect.
