Technical Field

[0001] This utility model relates to the field of anti-sloshing technology, specifically an anti-sloshing device for liquid tanks in fire trucks. Background Technology

[0002] When a fire truck is in motion, the liquid in the storage tank moves irregularly with the vehicle's movement. Under the influence of inertia, this generates a huge impact force, which has an extremely adverse effect on the smooth operation of the storage tank and the vehicle. In order to ensure the smooth operation of the fire truck and to prevent the liquid in the storage tank from excessively sloshing and damaging the storage tank, it is necessary to install an anti-sloshing device in the storage tank.

[0003] In a wave-damping device for liquid tanks in tank trucks, patent number CN210417789U, the damping rod and wave-damping plate effectively suppress the oscillation and fluctuation of the liquid inside the tank, thereby reducing the impact damage to the tank body caused by the oscillation of the liquid inside the tank. During tank storage and transportation, it improves vehicle driving stability, enhances vehicle driving safety performance and road transport safety. In addition, only one wave-damping plate is needed to effectively suppress the oscillation and fluctuation of the liquid inside the tank, which significantly reduces the difficulty of tank processing and manufacturing and reduces tank processing costs.

[0004] However, existing anti-sloshing devices have drawbacks. When the anti-sloshing plate is damaged, it needs to be replaced multiple times, which wastes a lot of time. At the same time, they cannot provide secondary anti-sloshing protection for the tank when there is too much liquid. Utility Model Content
