With the rise of the water transport industry and the development of the shipbuilding industry, the ship load has become larger and larger, and the transportation capacity has also been greatly improved, so the requirements for channel navigation have also been improved.
For the channel, it is also divided into several levels. In the past, some water depth requirements of the channel could not meet the navigation requirements of the water area, so it is necessary to set warning positioning points in the shallow water channel to remind the navigation safety of navigation vessels. Such warning signs generally use plastic buoys
to ensure that only ships on water can see them. At night, the buoys are equipped with solar beacon lights to ensure that they can be seen from afar and work. Some channels will be connected to the LAN according to the use requirements, and displayed on the radar, so that passing ships can be displayed and marked on electronic equipment, so that the preparation time can be adjusted in advance to avoid danger.
The water plastic channel buoy is made of high-strength polyethylene plastic through rotational molding technology. The obvious advantage of this material is that it has good corrosion resistance and wear resistance, and can be used for a long time in harsh seawater environment. Compared with the early steel navigation aids, the channel buoys have multiple advantages, such as maintenance free, low cost and long service life.
