[0002] The inner float is a floating top cover that floats on the liquid surface of the oil tank and rises and falls with the oil. It can be suitable for docking tanks and lap tanks of various sizes. It does not pollute the oil or chemicals itself, can reduce the volatilization loss of the medium, and prevent air pollution.

[0003] In order to solve the problem that "the existing floating plate is not easy to maintain stability inside the oil tank", the Chinese patent with the publication number CN116395283B discloses a fully liquid-connected assembled double-disc inner floating plate, including: a steering part; the mounting part is arranged outside the steering part; the floating part is arranged below the steering part; the buffer part is arranged below the floating part; the partition part is arranged above the mounting part; by fixing the stabilizing bar inside the oil tank, it is convenient to constrain the steering frame to avoid its large-scale adjustment, and the steering frame is provided with an idler wheel, so as to facilitate the reverse adjustment between the driving frame and the control ring, so that it is convenient to drive the fixed frame and the floating block in the bottom area to rotate in the opposite direction, so that it generates a reaction force on the oil surface, thereby offsetting part of the thrust, so as to facilitate the maintenance of the stability of the oil surface. Although the existing technical problems have been solved, the following problems still exist:

[0004] In this technical solution, by adjusting the reverse frame and the fixed frame and floating block at the bottom of the control ring in reverse, a reverse force is generated on the oil surface to offset the thrust of the oil surface. This technical solution plays a certain role in the stability of the floating plate, but its stabilizing effect needs to be improved. Summary of the invention

[0022] 6. The fully liquid-connected double-disc inner float is provided with an inner column, so that a support can be formed under the float to prevent the float from being tightly attached to the bottom inner wall of the oil tank, thereby preventing the float from being unable to float flexibly due to the viscosity of the oil on the bottom inner wall of the oil tank.
