Description
Technical Field
The invention relates to the field of marine culture, in particular to a large-scale deep and open sea fixed type wind wave resistant culture platform.
Background
Traditional farms generally place a plurality of small-volume net cages in quiet shallow water near the coast, where the storm conditions are mild and the farms are generally not threatened by extreme storms, typhoons and the like. However, the disadvantages of shallow water culture near the bank are also highlighted, such as: the mobility of the seawater is poor, and the excretion of the cultured fishes is easier to deposit; the area available for offshore culture is limited, and offshore culture is increasingly saturated.
The advantages of marine culture in the deep and far sea and near sea and shallow water culture are that a wider culture area is provided; the seawater has high fluidity under the action of ocean current, and is rich in natural food for cultivating fish; the effective culture water body space of the unit water surface is improved by the larger water depth. The disadvantages are that the deep and far sea is generally an open sea area, the storm condition is severe, the culture net cage and the platform structure need to resist the extreme storm effect caused by storms, typhoons and the like, and the platform cost is obviously increased.
The existing aquaculture net cages are generally small in single volume, and large-scale aquaculture is usually formed by concentrated installation of a plurality of small net cages. The small net cage group mode has limited effect on reducing the engineering cost of the unit culture water body, and the whole economy is general.
The existing wind and wave resistant culture platform is characterized in that the net cage is used as an independent frame and integrally moves up and down with the platform through a lifting platform or an auxiliary equipment mechanism, the culture platform is redundant in structure, the structural redundancy is obvious along with the increase of the volume of a single net cage, and the economy of large-scale platform is poor.
The existing wind wave-resistant culture platform avoids wind waves through temporary migration, repeated pile plugging and unplugging can be caused to the large culture platform through temporary migration, on one hand, the equipment cost for realizing the pile plugging and unplugging function of the culture platform is additionally generated, and on the other hand, the actual operation cost for using a supporting tug wheel and the like required by the temporary migration is additionally generated.

The vertical pipe structure comprises 8 vertical pipes which are respectively positioned at four vertical edges of the external frame and at the middle position of two adjacent vertical edges.
The top horizontal tube structure comprises 6 top horizontal tubes which are respectively positioned at four edges of the top surface of the external frame and two symmetrical axes of the top surface of the external frame.
The bottom horizontal tube structure comprises 6 bottom horizontal tubes which are respectively positioned at four edges of the bottom surface of the external frame and two symmetrical axes of the bottom surface of the external frame.
The vertical pipe structure department is connected with vertical guide rail, sets up vertical long banding spacing recess in the guide rail, and the spacing slider that is provided with in the spacing recess, slider connect in side direction netting.
The top of scalable netting welds in vertical tubular construction, and the side of scalable netting is fixed in vertical steel cable, and vertical steel cable is fixed in the side of guide rail.
The bottom end of the vertical steel cable at least extends to the middle horizontal pipe structure.
And a locking structure for locking the sliding block is further arranged on the vertical pipe structure.
Under the simple circumstances, can set up inside external frame with whole liftable netting to reciprocate inside external frame, lie in the fixed netting of lower part inboard during the removal, thereby can not receive the hindrance.
Besides, the following steps can be provided: the top horizontal netting is symmetrically divided into four top separation nettings which can independently move by two symmetrical axes on the top surface of the external frame; each lateral net is divided into two side-surface separation nets by a vertical symmetrical axis which is arranged between two vertical edges outside the lateral net; wherein, every top is separated the etting and is connected and separate the etting and form an independent body in two sides, and through such setting, the guide rail can set up in the external frame outside, and liftable etting also can set up in the external frame outside, the operation of convenient removal.
When the wind waves are small, the liftable netting can be pushed to the top end like a box, and the fish in the culture platform can move in a larger space.
When wind waves come, the liftable net is pushed to the bottom end like a box, and at the moment, fish in the culture platform are located below the sea surface and are not easy to be impacted by the wind waves.
Most of the time, the wind wave is small, so the living environment of the fishes is large.
