Quickly sinking influences to be preferably minimized, as shown in Figure 7；Then cable wire 10 is discharged, torpedo anchor is made quickly to sink simultaneously under Gravitative Loads
Injection sea bed, as shown in Figure 8；Cable wire 10 is then pulled up, anchor body 4 is made to be extracted out from sleeve 6, the sleeve 6 with empennage 1 is retained in sea
In bed, that is, complete the construction operation of carried torpedo anchor.Anchor body 4 anchors basic state as shown in figure 9, anchoring basis exists after removing
Possible posture is as shown in Figure 10 under the action of follow-up anchor chain pulling force.
Fig. 2 ~ Figure 10 gives a kind of the case where three empennages.In fact it is also an option that the empennage of other quantity, such as schemes
11 give a kind of four tail structure schematic diagrames.
Advantages of the present invention is as follows：The inner hollow of anchor body, middle vacancy are packed into filler, and filler can be selected highdensity
Material such as concrete, old metal etc., i.e., can be the larger sea bed of the sleeve depth of penetration with empennage using the larger anchor body of dead weight
In, then the lifting of anchor body, removal, it is retained in sea bed the sleeve with empennage and forms anchoring basis, can be used for mooring net cage
It uses；Anchor chain mooring on from the mooring hole on anchor body center line empennage relatively far away from, is made fish by the carried torpedo anchor of this technology
Mine anchor is by eccentric load, and by itself and the soil body after eccentric load more complicated friction and relative motion are occurred for torpedo anchor, no
It is easy to be pulled straight out, the load of bigger can be born；And the volume of the sleeve with empennage is relatively small with quality, cost is relatively low,
Its surface area is larger, and larger frictional force can occur with the soil body, can provide larger mooring forces；Working anchor body is repeatable to be made
With, therefore the construction cost for sharing each anchoring basis is relatively low.
The length of traditional torpedo anchor is generally more than 10 m, and weight is more than 100 tons.If be used for mooring net cage, it is clear that quality with
Volume is excessive, and the cost is relatively high, it is difficult to promote the use of.Moreover the load that the load that net cage is subject to usually is subject to than ocean platform
It is much smaller, therefore the torpedo anchor of mooring net cage should not directly apply mechanically the torpedo anchor of traditional mooring ocean platform.This technology is to traditional fish
Mine anchor has carried out certain improvement, has not only considered torpedo anchor injection sea bed and has needed enough dead weights, but also has taken into account anchoring basis
Volume should not be too large with dead weight, the unsuitable excessively high actual demand of cost, it is proposed that the anchor body for conducting oneself with dignity larger and the sleeve with wing plate
The mentality of designing that can be separated from each other so that torpedo anchor can meet the mooring needs of 20 m ~ 50m depth of water net cages, and have quality phase
The advantage relatively low to smaller, installation cost.
The case where partial shape and part connection type of empennage and anchor body are shown only in attached drawing, according to carried thinking,
Shape, quantity, sleeve and the anchor body that empennage can be changed are connected with each other mode, and the anchor body for forming other correlation types is separable
