Abstract
The invention discloses a limiting method and device for a floating type ship collision prevention floating body. The limiting device comprises a floating body and a stop limiting device, wherein the floating body is sleeved on an auxiliary pier, and can move up and down; the upper surface or the lower surface of the floating body is provided with a stop limiting device for limiting the floating body from vertically floating upwards; a one-way limit valve is installed on the floating body; a cavity is formed inside the floating body; and the one-way limit valve is connected to the cavity inside the floating body. Under the effect of the stop limiting valve, the vertical height of the floating body is limited, the floating body is positioned at the highest vertical height permitted by the stop limiting device; if the water level rises continuously, the hydraulic pressure suffered by the surface of the floating body is increased, and when the hydraulic pressure is increased to the pressure set by the one-way limit valve, the one-way limit valve is opened and the water enters into the cavity inside the floating body, the vertical resultant force suffered by the floating body is reduced, and finally the force is balanced at the limit position; and therefore, the defect that a floating-type ship collision prevention floating body brings adverse effects and potential safety hazards to bridges in an extreme water level or a high water level is overcome.
