Elastic body lamp buoy

Abstract

The present invention discloses one kind of floating lamp with elastic float, and aims at providing one kind of floating lamp with elastic float possessing high shock strength, high corrosion resistance, easy manufacture, no maintenance and long service life. The floating lamp includes signal lamp, lamp holder, day mark, float, upper cover, lower support, central tube, connecting rods, tail tube and balancing weight. The float includes elastic foamed core and elastic shield to cover the elastic foamed core with no interval in between. The present invention is used as safe mark for boats and ships.

Description

technical field [0001] The invention relates to a device for aiding navigation on water, in particular to an elastic body light buoy. Background technique [0002] Navigation marks are important navigation aids to guide ships to navigate safely. For a long time, steel buoys have been the main buoys on the water, but with the development of the economy, the density of ships on the waterway has increased, which makes the steel buoys show the following disadvantages: [0003] 1. Due to the high strength and hardness of steel buoys, ships colliding with them, especially small ships, will cause greater damage; [0004] 2. Due to the poor impact resistance of steel buoys, large ships colliding with them will damage them and cause the buoys to sink after flooding. The sunken buoys will pose a threat to the navigation of ships; [0005] 3. Due to the heavy weight of steel buoys, it is difficult to transport, release and recycle buoys; [0006] 4. Since st...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the high strength and hardness of steel buoys, ships colliding with them, especially small ships, will cause greater damage;

[0004] 2. Due to the poor impact resistance of steel buoys, large ships colliding with them will damage them and cause the buoys to sink after flooding. The sunken buoys will pose a threat to the navigation of ships;

[0005] 3. Due to the heavy weight of steel buoys, it is difficult to transport, release and recycle buoys;

[0006] 4. Since steel buoys are easy to corrode, the maintenance workload such as rust removal, removal of marine deposits, painting, etc. is heavy and the follow-up cost is high

[0008] FRP buoy has the advantages of corrosion resistance, easy coloring and light weight, but the surface of FRP buoy is fragile, its impact resistance is very poor, and its performance of aging resistance and temperature change resistance is also poor

[0009] Chinese Patent Publication No. CN1046711, published on November 7, 1990, discloses a plastic buoy named "All-plastic navigation buoy", which has the advantages of corrosion resistance, easy coloring, and light weight, but the surface of the plastic buoy is relatively fragile , its impact resistance is poor, and its aging resistance and temperature change resistance are also poor

[0010] The Chinese Patent Publication No. is CN2414000, and on January 10th, 2001, the publication date discloses a rubber buoy called "The Buoy Drum Used in Water Navigation Mark Setting", which has the advantages of impact resistance and corrosion resistance, but Rubber buoys are not easy to color and difficult to form and process

[0011] Moreover, the floating bodies of the above-mentioned FRP buoys, plastic buoys and rubber buoys are filled with foam materials in the shells made of glass fiber reinforced plastics, plastics or rubber. The water absorption rate of the filler is high, so that the floating body has the disadvantages of large buoyancy loss and poor physical properties that are difficult to overcome

[0012] Therefore, there is no navigable buoy in the prior art that has the advantages of impact resistance, corrosion resistance, easy processing, long maintenance-free time, low maintenance cost, and long service life.
