Offshore navigation mark based on wave energy power generation

Abstract

The invention discloses an offshore navigation mark based on wave power generation, and belongs to the field of offshore navigation marks. According to the offshore navigation mark based on wave powergeneration in the scheme, a U-shaped ring groove and a sealing curtain are matched, and a water draining groove and a sealing ring are matched, so that control over the liquid level height of residual seawater in a transition air chamber is realized, and dynamic balance of the liquid level height is achieved; the residual seawater carried by seawater on the navigation mark can be reduced, air inlet and outlet of a central pipe are not easily influenced, normal work of a symmetrical wing gas turbine is not easily influenced, and damage or a direct failure of the symmetrical wing gas turbine isnot easily caused; meanwhile, a navigation mark main body, a floating block and an outer floating cover are integrally similar to a tumbler through the arrangement of a counterweight ring, so that overturning caused by the fact that the seawater impacts the lower side is not prone to being caused; and a wave-proof fiber curtain is arranged between a main cover body and the counterweight ring, sothat sea waves can be divided, the change of the liquid level in the outer floating cover is more stable, and the navigation mark main body and the floating block are more stable.

Description

technical field [0001] The invention relates to the field of offshore navigation aids, in particular to an offshore navigation aid based on wave energy power generation. Background technique [0002] Navigation mark is the abbreviation of navigation aid mark, which indicates the direction of the channel, the boundary and the obstacle, including the river crossing mark, the coastal mark, the guide mark, the transition guide mark, the head and tail guide mark, the side mark, the left and right navigation marks, and the position indication mark , flood marks and bridge and culvert marks, etc. It is an artificial sign that helps guide the ship's navigation, locates and marks obstructions and expresses warnings. [0003] Wave power generation uses the energy of waves as the power to generate electricity. Ocean waves contain huge energy, and the power P≈HTkW / m per meter of crest width of sinusoidal waves. In the formula, H is the wave height and T is the wave period. The energ...

Problems solved by technology

[0005] However, in the process of using wave energy to generate electricity for the navigation mark, the seawater carried by the excessively high waves is easy to hit the navigation mark, and some seawater will remain on the navigation mark, and it is easy to accumulate in the air chamber connected by the central tube of the wave power generation device. It will affect the air in and out of the center tube, affect the normal operation of the symmetrical wing turbine, and seriously cause the symmetrical wing turbine to be immersed in seawater for a long time, causing damage or direct failure of the symmetrical wing turbine
