Description

Technical Field

[0001] The invention relates to the technical field of anti-collision warning equipment, and in particular to a multi-level active anti-collision warning equipment for bridges. Background Art

[0002] Anti-collision warning equipment is one of the essential safety facilities for modern bridges. It can effectively ensure the safety of ships passing through and avoid accidents such as bridge collisions in weather with low visibility such as heavy fog.

[0003] The common bridge collision warning equipment on the market is mainly divided into two parts: front-end equipment and rear control console. The front-end equipment is mainly laser radar, which calculates the position of the ship through radar and divides the collision risk into multiple levels. When the corresponding level is reached, the rear control console sends a radio reminder through the base station to remind the ship driver to adjust the course in time to avoid collision. There are some functional deficiencies in actual use and there is room for improvement. For example, in foggy weather, even if the reminder information is received, there is a lack of reference when adjusting the course, and there is no function of instant feedback reference adjustment; secondly, the current early warning equipment laser radar is mostly mounted on the bridge pier through a steel fixing sleeve. As the connecting bolts age and the fixing sleeves deform and become loose, the connection is prone to loosening and slipping, and the later reinforcement is more troublesome, and it does not have the function of tightening the connection to prevent loosening; in addition, in the low temperature weather in autumn and winter, water molecules in the air are easy to adhere to the glass mask at the front end of the laser radar, causing laser scattering, affecting the measurement accuracy, and it does not have the function of local warming to prevent condensation and frost.

[0004] Now, a new type of bridge anti-collision multi-level active warning equipment is proposed to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a multi-level active warning device for bridge collision prevention, so as to solve the problem of lack of instant feedback reference adjustment function proposed in the above background technology.

[0007] The heading guidance mechanism comprises a mounting plate, which is arranged between one side of two groups of aluminum alloy covers, an LED guidance light board is installed at the front end of the mounting plate, and a wire is arranged between one side of the LED guidance light board and the top of the aluminum alloy cover.
