A kind of ocean wave observation buoy

Abstract

The invention discloses an ocean wave observation buoy, which comprises a buoy-type wave-measuring ball (1), the inside of the buoy-type wave-measuring ball (1) is sealed with a GPS positioning device, and the buoy-type wave-measuring ball (1) A solar panel (100) that supplies power to a GPS positioning device is also installed on the surface; the buoy type wave measuring ball (1) can still completely float on the ocean surface under the gravity dragging effect of the counterweight (5) Above, a first steel cable (2) is fixedly installed at the center of the bottom of the buoy-type wave measuring ball (1), and the lower end of the first steel cable (2) passes through the suspension ball (3) and the positioning ring ( 4) It is fixedly connected with the counterweight (5) to form a whole. The invention has a simple structure, can ensure that the buoy-type wave-measuring ball can be accurately returned to its original position when the weather is calm, eliminates the phenomenon of the buoy-type wave-measuring ball drifting randomly, and helps observers to accurately find the starting point or the middle point of the buoy-type wave-measuring ball.

Description

technical field [0001] The invention relates to research equipment related to ocean surges, in particular to an ocean wave observation buoy. Background technique [0002] Waves are essential basic data in marine scientific research and marine engineering design and construction. Aiming at the collection of this important data, a variety of ocean wave detection instruments have appeared at home and abroad; [0003] 1. The pressure wave measuring instrument, in short, uses the underwater high-precision pressure sensor to measure the pressure change caused by the wave movement. This is the most traditional measurement method at present, so as to obtain the parameters related to the wave height. ; [0004] 2. Acoustic wave measuring equipment, which uses underwater acoustic pulses to measure the velocity of the flow or the distance to the water surface; [0005] 3. Buoy-type wave measurement. It should be noted that there are currently two types of wave measurement buoys. One ...

Problems solved by technology

[0006] Among the above-mentioned measurement methods, the buoy-type wave measurement has become more and more accurate today with the GPS positioning becoming more and more accurate. However, in the actual application process, the buoys often float freely without a fixed point. It can be used for reference, but the main factors causing the drift are wind, ocean currents and ebb and flow, the most important of which is the disturbance of the buoy by the wind and ebb and flow. Even in a calm period, the position of the buoy ball is uncertain. It brings a lot of interference to the measurers from the starting point or the center point (for the content of this part, please refer to the technical characteristics and actual measurement analysis of the current ocean wave measurement published by the "Journal of Ocean Technology" in August 2015); To solve this problem, the current common method is to use chains and counterweights on both sides of the buoy to fix them respectively. Although this method can limit the movement of the buoy within a certain range, the accuracy of the test data is still poor. The reason is that the buoy is still free to float and move between the two counterweight cement blocks

[0007] At the same time, there is another major factor that seriously restricts the buoy-type wave-measuring equipment, that is, its built-in GPS positioning device consumes a lot of power during non-stop work, and the usual unattended buoy-type wave-measuring A commonly used solution to the problem is to install several solar panels and corresponding battery packs on the surface of the buoy to realize uninterrupted power supply to the GPS positioning device, but after using it for a period of time, the positioning information of the GPS positioning device will be due to The current is not enough and starts intermittently. Because the battery cannot get enough charging current, this phenomenon is particularly obvious, especially at night. The main reason is that the ocean environment is different from the inland environment. Evaporation on higher temperature solar panels (mainly during the day) will crystallize and attach a layer of salt frost, and this layer of salt frost will seriously corrode the glass cover of the solar panel (see details published in 2010 in " Reliability Analysis of Marine Solar Cells in the Journal of Marine Engineering), if it is not cleared regularly, the uninterrupted work of the GPS positioning device can only be realized by regularly replacing the solar panels, so the current buoy-type wave measuring equipment is limited by the current supply The problem is that it cannot be truly unattended. In addition, the buoy-type wave measuring equipment in the vast sea is often an ideal shelter for seabirds, and a large amount of feces excreted by them will also adhere and solidify on the surface of the solar panels, directly affecting Power supply to battery pack
