Problems solved by technology

Its disadvantages are: the structure of its floating chamber is the same as that of the traditional floating chamber: bulky structure, large volume, heavy quality, inconvenient use and maintenance, and easy to be stuck or forcibly dragged away by ice floe in the case of drift ice in winter. Among them, the hollow metal floating chamber is easy to corrode, easy to be damaged by impact, poor impact resistance and poor stability; the structure of the universal joint is complex, and it cannot really move freely in all directions, and it is easy to wear and tear after long-term use. short lifespan and need to be replaced periodically
[0004] Therefore, the existing products have the following deficiencies: heavy structure, poor impact resistance, poor stability, poor corrosion resistance, easy to wear, inconvenient use and maintenance

Embodiment Construction

[0018] Such as figure 1 , figure 2 As shown, the present invention includes a lamp 1, an ice guiding skirt 2, a floating chamber 4, two suspension rings 5, a counterweight 6, an anchor chain 7, and sinking stones 8. The floating chamber 4 includes a core tube 40, three floating bodies 41, 42, 43, the floating body 41, 42, 43 is fixed in series on the periphery of the core pipe 40 through the central hole, and the floating body 41, 42, 43 is composed of the elastic foam inner core 4a and coated on the elastic foam inner core 4a surface of the elastic armor 4b, there is no gap between the elastic foam core 4a and the elastic armor 4b, the two ends of the anchor chain 7 are respectively connected to the bottom end of the core tube 40 and the sink through the connecting piece. The anchor chain 7 is a short anchor chain, and the anchor chain 7 includes three chain links. The surface of the chain rings is provided with a wear-resistant protective layer, and the material of the wea...

Abstract

A high-stationarity articulated stake for the navigation lamp is composed of lamp, floating chamber consisting of at least one floating body made of elastic foam core and elastic armour, and a central tube passing through said floating body, a sunk stone, and a short chain for linking the lower end of said central tube to sunk stone. Its advantages are high impact resistance, stability and anticorrosion nature.

Description

technical field [0001] The invention relates to a high stagnation activity type lamp post. Background technique [0002] Buoys are important navigation aids for safe navigation of ships. Their main functions are to mark the direction, boundaries and obstructions of the waterway, reveal relevant information about the waterway, and point out safe and economical waterways for ships to navigate. Most of the current buoys have a floating chamber structure so that the buoy can float on the water surface. The existing internal hollow floating chamber made of steel and other metals has a large mass. In order to have sufficient buoyancy, its volume is relatively large, so the structure is heavy and the consumption of metal materials is increased; the floating chamber is subjected to external wind, waves, etc. When impacted by water, current, ice, etc., due to the large impact area, violent shaking often occurs, which affects the stability of the buoy; due to the heavy structure, it ...
