Detect the piece and receive self action of gravity downstream, pull the stay cord, the stay cord drives pivot corotation, and first torsional spring rotates the energy storage along with the pivot, and after the raw materials was packed into in the fermentation cylinder, it receives the ascending buoyancy of raw materials to detect the piece, and the stay cord receives decurrent pulling force and reduces, detects piece upward movement, and first torsional spring drives the pivot reversal and makes on the stay cord winding revolving axle. The detection block is buried in the raw material and is kept balanced under the action of gravity, buoyancy and upward tension of the pull rope. The rotating shaft is kept still by the first torsion spring and the downward pulling force of the pull rope, and the scale indicated by the pointer on the disc is the initial scale.
In the process of fermenting the raw materials, the density of the raw materials changes, and according to a buoyancy calculation formula, when the volume of the detection block embedded in the raw materials is not changed, the buoyancy borne by the detection block is in direct proportion to the density of the raw materials. When different raw materials are used for brewing different wines, the density of the raw materials may become higher or lower in the fermentation process. When the density of the raw material is increased, the buoyancy force applied to the detection block is increased, and when the density of the raw material is decreased, the buoyancy force applied to the detection block is decreased. The buoyancy change that detects the piece, break the equilibrium state that detects the piece, detect the piece and move up or down, make the pulling force change that the stay cord received when detecting the piece motion, and then make the pivot rotate.
