Oceans account for 71% of the surface area of the earth. China clearly proposes to build a strong ocean country. The sea area of China is more than 300 ten thousand square kilometers, the land area is about 1/4, and the development space is huge. In advance, the fishery is an indispensable ring in marine economy and plays an important strategic position in marine economy.

The aquatic product is the optimal protein, the total amount ratio of essential amino acid to non-essential amino acid and semi-essential amino acid is consistent with the ideal protein mode of WHO/FAO. At present, aquatic products are increasingly favored by people, and the proportion of the aquatic products in animal protein food is gradually increased, so that the aquatic products become an important food source for people to live. The marine organisms are various in variety, have good nutrition and health care effects, have large resource development and utilization potential, and can provide a large amount of food such as fish, shrimps, shellfish, algae and the like for people every year. From the ecological point of view, the primary productivity of the marine phytoplankton on the earth reaches 43 x 10¹⁰The primary ocean productivity is 6000 million tons per year per ton of carbon per year, and theoretically at least 60 million tons per year of edible senior organisms can be provided to humans. Currently, fisheries only produce 1.2 million tons worldwide per year, providing only 22% of animal protein to humans.

The development and utilization of the ocean can effectively reduce the bearing capacity of the land ecological environment. United nations report that "the earth has been terrible, i.e., no action is taken to protect the environment, and human health is increasingly threatened". In the strategy of sustainable development, the sustainable safety of food is a primary problem, and the food acquisition is urgently required to pay more attention to the sustainability of ecological environment protection and resource utilization.

Due to the presence of the diversion protrusion 28, the flow velocity of the ocean current at the bottom is reduced, silt is easy to accumulate at the bottom of the bottle-shaped upright post 14, and the stability of the whole platform is usually facilitated. However, it is well known in the art that this is obviously detrimental to the lifting of the anti-slip elements and the action of the expansion mechanism when the bottom is heavily piled up, gradually to the outside of the bottle-shaped uprights 14, covering the anti-slip elements 20 as well.

Therefore, the further invention also provides a spiral protrusion 68 on the outer wall of the bottom of the bottle-shaped upright post 14 and the outer wall of the anti-slip component 20, and the protrusion 68 extends spirally along the outer wall of the bottom of the bottle-shaped upright post 14 and the outer wall of the anti-slip component 20 in the axial direction.

The flow direction of the fluid is changed by controlling the spiral direction of the bulge, so that turbulent flow is better formed, and the peripheral silt is washed away. When the tube has both left and right turns alternating, it has a better effect on creating turbulence than a single direction spiral.

In order to enhance the turbulent flow effect, the cross-sectional shape of the protrusion 68 may be approximately rectangular, triangular, circular, semicircular, or trapezoidal. For the effect of forming turbulent flow, rectangular > trapezoidal > triangular > circular > semicircular in the case where the heights of the protrusions 68 are the same, and therefore, approximately rectangular protrusions 68 are preferable, and the turbulent flow state can be maximized. The bottom outer wall of the bottle-shaped upright post 14 and the bulge of the outer wall of the anti-skid component 20 respectively have certain height, width and inclination angle according to different shapes; the number of the protrusions 68 is at least 1, and the protrusions are distributed uniformly or unevenly on the inner wall, and can be arranged in an increasing or decreasing manner according to the circumferential angle, and the protrusions can also extend continuously or discontinuously. The uneven arrangement of the protrusions 68 and the intermittent manner of the protrusions 68 can better disturb a single turbulent flow state, form a more complex fluid state and enable the scouring effect to be better.
