Problems solved by technology

[0003] However, due to the irreversibility of bottoming out, the traditional seabed base still has a 10-20% tipping probability when deployed under the conditions of professionals, special vessels and special equipment, which is high in cost, high in risk, and poor in effect; moreover The most important thing is that most of the continental shelf and slope areas are the operation areas of marine trawling fishery, and the probability of the seabed base being towed up can reach 1 time / 15 days. Since it cannot be turned over automatically after being towed over, not only the observation is interrupted, but also the probability of loss is also high. up to 90% or more
[0004] For this reason, we have invented a self-righting seabed foundation for ocean observation that has not yet been established at home and abroad, which overcomes the shortcomings of traditional seabed foundations such as difficulties in deployment, high deployment costs, and self-resetting when towing and overturning. Provide more suitable observation equipment

Embodiment Construction

[0028] According to the content of the invention, the specific construction operations for making the self-righting seabed foundation are as follows:

[0029] (1) According to the proportion control, 316L stainless steel is used to build a "three-layer structure" in the vertical direction of the self-righting seabed foundation;

[0030] (2) According to the setting of fixed ratio control, proportional transfer and apparent dumping function of self-righting seabed foundation, make self-righting seabed foundation apparent structure mold, and then use glass fiber reinforced plastics to manufacture self-righting seabed foundation appearance structure;

[0031] (3) Build anti-collision supports according to the depth of free fall in water;

[0032] (4) Installation of observation instruments and equipment;

[0033] (5) Anti-electrochemical treatment;

[0034] (6) Anti-biological adhesion treatment.

Abstract

The invention belongs to the field of marine observation platform type technical equipment, and provides a self-righting seabed base for marine observation. The main creation of the self-righting seabed base comprises: (1) an elliptic curved surface design with a stable transfer function; (2) the arrangement of a convex turning point with a lever control function; (3) a 'three-layer structure' with a strict proportion; (4) a proportional control 'geometric proportion transfer' control method; (5) an adjusting method for the top proportion; (6) construction of an apparent dumping function; and (7) strict mathematical control of the overall structure manufacturing, wherein the fixed ratio is determined as follows: the seabed base can be simply laid by non-professional personnel, non-professional ships and non-professional equipment, and has a special function of automatically righting the optimal observation position in all directions after being disturbed and turned over to overcome the defects of difficult laying, high laying cost, incapability of self-resetting after being dragged and turned over and the like of the traditional seabed base, and provide more suitable observation equipment for observation of the ocean current of the continental shelf and the underflow of the continental slope.

Description

technical field [0001] The invention belongs to the field of ocean observation platform type technical equipment, and in particular relates to a self-righting seabed foundation for ocean observation. Background technique [0002] Bottom-based fixed-point seabed-based continuous observation is the most classic and ideal way to obtain reliable and accurate ocean current data, and it is also the preferred choice for continental shelf ocean current and continental slope bottom current observation. It is worth pointing out that my country is one of the countries with the widest continental shelf in the world, while the world's continental shelf area accounts for about 7.5% of the total ocean area, and the continental slope area accounts for about 7.8% of the total ocean area. [0003] However, due to the irreversibility of bottoming out, the traditional seabed base still has a 10-20% tipping probability when deployed under the conditions of professionals, special vessels and spec...
