A sampling tube for oil tanks

Abstract

This invention discloses an oil tank sampling cylinder, relating to the technical field of oil tank sampling equipment. It includes a housing; a handle is located at the top of the housing, one end of which passes through the housing and is positioned inside, movably connected to the housing. The end of the handle is bent inward to form a limiting structure. A positioning mechanism is located at the bottom of the housing, a driving mechanism is located on one side of the housing, and a storage mechanism is located inside the housing. The interior of the housing is a hollow structure, and the storage mechanism and driving mechanism are positioned correspondingly. A height measuring structure monitors the remaining liquid level inside the oil tank, automatically calculating the length of the connecting rope to be released, avoiding repeated bending for confirmation. An automatic quantitative operation, using a float and a return spring, automatically raises the slider when the sampling cylinder reaches the liquid level, conveniently reminding the operator.
