A bridge height limiting device

Abstract

The invention discloses a bridge height limiting device. The bridge height limiting device comprises a supporting pipe arranged on a pier of a bridge, two gaskets are arranged at the top of the supporting pipe in a bilateral symmetry mode, each gasket and a bridge body are fixed through a retaining screw, and an LED array display screen is arranged at the position, close to the top, of the left side of the outer surface of the supporting pipe. A dividing ruler is arranged on the right side of the front end face of the LED array display screen, a control unit is arranged on the right side of the top of the LED array display screen, and a caution light is arranged in the middle of the bottom of the LED array display screen. Two connecting rods are arranged at the positions, close to the top,of the right side of the supporting pipe in a vertically symmetric mode, and a sliding resistor is fixedly arranged at the ends, away from the supporting pipe, of the two connecting rods. The bridgeheight limiting device is simple in structure and low in manufacturing cost, the height value of permitted height of a passing ship can be automatically displayed through the LED array display screenaccording to the height of the water surface, and the displayed height value of the permitted height is precise.

Description

Technical field [0001] The invention relates to the technical field of bridges, in particular to a bridge height limiting device. Background technique [0002] Existing bridges will set height limit signs at the bottom of the piers during use. However, the height limit signs set at the bottom of the existing bridges have a single function, and it is often impossible to give real-time height limit numerical recommendations based on the fluctuations of the water level. When driving at night, due to the lack of correct warning signs, many passing ships cannot pass through the bottom of the bridge normally, causing great inconvenience to passing ships, which will make the passing ships unable to pass normally. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a bridge height limiting device, which can solve the above-mentioned problems in the current technology. [0004] To solve the above problems, the present invention adopts ...
