Aquaculture net cage is generally made up of net cage frame system, netting system, mooring system and auxiliary facility system.Wherein mooring system is net cage foundation in water, generally comprises end anchor and hawser, and end anchor is connected with net cage by hawser.End anchor mainly has three kinds of modes: anchor, clump anchor and piled anchor, and wherein clump anchor is moderate, aquaculture net cage fixing in more typically.
Clump anchor rely primarily on clump from gravity to balance the pulling force in anchor line vertical and horizontal direction, hawser and seabed angle are usually no more than 30 °.Under inclement weather conditions, clump anchor likely cannot undertake excessive pulling force that hawser passes over and the phenomena of drag of anchor occurs.Specifically, the failure form of clump anchor has: the frictional force between clump anchor and sea bed moves in parallel less than the horizontal component of hawser pull；Clump anchor is subject to bigger hawser pull and topples and movement of rolling.
In order to improve the anchoring ability of clump anchor, should expanding the floor space of clump anchor on the one hand, increase contacts and friction area with sea bed as far as possible；The center of gravity of clump anchor should be reduced on the other hand, improve the resistance to capsizing of clump anchor.Usually, the shape of clump anchor has square, cuboid, trapezoidal stage body etc..And these common shapes, it is not necessarily the geometry shape that resistance to capsizing is best.Namely, when volume is identical, the resistance to capsizing of the clump anchor of the shape such as square, cuboid, trapezoidal stage body is generally not maximum.Accordingly, it would be desirable to develop the novel concrete pier anchor shape that a kind of resistance to capsizing is higher, meet the demand of actual application environment.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of clump anchor for cage culture, and its floor space is big, center of gravity is low, resistance to capsizing is strong, can improve the anchor force of clump anchor.
The technical solution of the utility model is as follows:
Clump anchor for cage culture, it is characterized in that, sink including the cement that entirety is " ten " word intersection beam-like and stick together, cement sink the center, upper surface sticked together be provided with main ring turn round, cement sinks the end face center of the transverse beam sticked together and longitudinal beam and is provided with secondary ring and turns round, cement sink stick together transverse beam, longitudinal beam bottom width more than the width of end face.
The described clump anchor for cage culture, it is characterised in that described cement sink stick together transverse beam, longitudinal beam end face be the trapezoidal faces of inclination, trapezoidal faces from bottom to cement heavy stick together centroclinal；Cement sink stick together transverse beam, longitudinal beam side be the quadrilateral surface of inclination, the cross wire that the sinking to cement from bottom of quadrilateral surface sticks together tilts.
The described clump anchor for cage culture, it is characterised in that described cement sinks the transverse beam, the end face of longitudinal beam and the angle of horizontal plane that stick together and is generally between 45 ° ~ 80 °.
The utility model has the advantages that:
This utility model novel in structural design, cement sink stick together volume identical when, cement sinks the shape that sticks together and has the advantages that the moment of inertia is relatively big, center of gravity is relatively low, has bigger resistance to capsizing, it is possible to increase the anchor force of clump anchor.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Referring to accompanying drawing:
Clump anchor for cage culture, sink including the cement that entirety is " ten " word intersection beam-like and stick together, cement sink the center, upper surface sticked together be provided with main ring turn round 1, cement sinks the end face center of the transverse beam 2 sticked together and longitudinal beam 3 and is provided with secondary ring and turns round 4, cement sink stick together transverse beam 2, longitudinal beam 3 bottom width more than the width of end face.
Cement sink stick together transverse beam 2, longitudinal beam 3 end face be the trapezoidal faces 5 of inclination, trapezoidal faces 5 from bottom to cement heavy stick together centroclinal；Cement sink stick together transverse beam 2, longitudinal beam 3 side be the quadrilateral surface 6 of inclination, the cross wire that the sinking to cement from bottom of quadrilateral surface 6 sticks together tilts.
Cement sinks the transverse beam 2, the end face trapezoidal faces 5 of longitudinal beam 3 and the angle of horizontal plane that stick together and is generally between 45 ° ~ 80 °.
Cement described in the utility model is heavy to stick together, and the heavy transverse section that sticks together of cement is decussation symmetrical rectangular shape, and the rectangular dimension of both direction is identical.When floor space is identical, compared with square, rectangle, circle, decussation symmetrical rectangular shape has bigger the moment of inertia, thus its resistance to capsizing is bigger.
The heavy surrounding oblique section that sticks together of this utility model cement is tilted to vertical central axis to end face by bottom surface, forms the shape that big top, bottom is little, and center of gravity is relatively low, thus its resistance to capsizing is bigger.
Cement described in the utility model is heavy to stick together, and cement sinks stick together 4 secondary rings that arrange of surrounding Side symmetrical and turns round 4, is used for carrying, construct and mention moorstone and uses.
This utility model work progress at sea is as follows:
This utility model is transported to the marine site anchor points specified, and on crane gear suspension hook, rope tangles cement and sinks the main ring on sticking together and turn round 1, and construction auxiliary is restricted and tied up in 2 or 4 symmetrical secondary rings torsions 4.Anchor lifting is stood on predetermined sea, is slowly drop down in sea water, until contact seabed.Tie up to the auxiliary rope sinking perpendicularity for controlling, maintain, correct in work progress of constructing that secondary ring is turned round on 4, it is ensured that clump anchor is steadily placed on sea bed.
Be positioned over the cement on sea bed heavy stick together need to change position and during lift-off waters, at sea ferry construction process is as follows: on crane gear suspension hook, rope tangles cement and sinks on sticking together secondary ring and turn round 4, lifting makes the heavy bottom surface that sticks together of cement depart from sea bed gradually, until the heavy bottom surface that sticks together of cement completely disengages from sea bed, then lift-off waters.
If rope on suspension hook being tangled cement sink the main ring on sticking together and turn round that 1 lifting cement is heavy to stick together, the heavy bottom surface that sticks together of cement is bigger with sea bed adsorption, it is necessary to bigger lifting load just can make the heavy bottom surface that sticks together of cement depart from sea bed entirety.
Rope on suspension hook being tangled cement sink on sticking together secondary ring and turn round that 4 lifting cement are heavy to stick together, the heavy inclined shape that sticks together of cement is mentioned, and its bottom surface and sea bed gradually disengage, thus required lifting load is relatively small.
Visible, cement sinks the stick together secondary ring of upper setting and turns round 4, is used for mentioning moorstone when transporting clump anchor, and convenient transhipment reduces discarded clump anchor and forms barrier in seabed and affect follow-up ocean and produce.
