Description
Technical field
The utility model is related to sea-anchor technical fields, and in particular to a kind of novel sea-anchor.
Background technology
Anchor refers generally to ship anchor, is the critical piece of anchoring and mooring system, is the utensil made of iron that brings to, aboard ship with iron chains company,
Anchor is thrown at the bottom, ship can be made to come to a complete stop.As ocean development is promoted to deep water, new requirement is proposed to anchoring, in deep water,
If remaining that anchor chain lower end and seabed are tangent to ensure the grip of anchor, required chain is very long.Therefore, to study can bear
The anchor of vertical component such as uses cement pouring weight or anchoring pile；When meeting lithology seabed and cannot drive piles, drill-pouring anchor can be used
Stake.Some anchors are designed according to specific seabed, are used in the seabed for not meeting design requirement, the working performance of anchor
With regard to poor.
Negative pressure barrel type anchor is common sea-anchor, and the negative pressure being to rely in bucket inserts anchors into seabed.Its vertical carrying energy
Power comes from the friction of inner and outer barrel wall, therefore, very sensitive to the horizontal swing of bucket.Effect of the anchor in anchorage tension horizontal component
Under, horizontal swing occurs and is inevitable, this will weaken the vertical bearing capacity of anchor significantly.Existing sea-anchor is because being provided only with one
Negative pressure cavity may generate negative pressure deficiency because of pressure chamber, cause the withdrawal resistance of sea-anchor small；The outer wall of anchor core is usually flat without support
Weigh structure, will produce apparent horizontal swing, and low with the combined with firmness of seabed silt.
Therefore it is badly in need of providing a kind of sustainable sinking, is firmly combined with seabed, vertical bearing capacity and big novel of withdrawal resistance
Sea-anchor.
Utility model content
The purpose of this utility model is the deficiency for existing sea-anchor, provides a kind of sustainable sinking, jail is combined with seabed
Gu the novel sea-anchor of vertical bearing capacity and withdrawal resistance greatly.
The utility model provides following technical solution：
A kind of novel sea-anchor, including anchor cylinder and the anchor core inside the anchor cylinder, anchor core tail portion are equipped with cone
Anchor head, be equipped with first partition and second partition inside the anchor cylinder successively from top to bottom, the top of the anchor core is equipped with boss
And the boss is located above the first partition, and the first negative pressure cavity, the anchor are formed between the boss and anchor cylinder top
The second negative pressure cavity and third negative pressure cavity are divided by the second partition between core and the anchor cylinder side wall, the anchor cylinder, which is equipped with, to be divided
First through hole, the second through-hole and the third through-hole not being connected with first negative pressure cavity, the second negative pressure cavity and third negative pressure cavity；
The lateral wall of the anchor cylinder is hinged with the first anchor fluke, and one end of supporting rod, the supporting rod are connected on the inside of first anchor fluke
The other end be connected with the anchor core.
Preferably, several second anchor flukes are equipped with outside the anchor head, the balanced capacity of anchor core can be improved, prevent sea-anchor from shaking
Dynamic, when anchor core is inserted into seabed, the second anchor fluke can increase the contact area in sea-anchor and seabed, and reinforcement is firmly combined with seabed
Property.
Preferably, the top of the anchor cylinder is equipped with anchor ring, for connecting anchor chain.
Preferably, it is connected with round table-like fixed block between the anchor ring and the anchor cylinder, intensity is high, and anchor ring is not easily broken
It splits.
Preferably, equally distributed swelling seam in an axial direction is equipped with outside the anchor cylinder, effect is swelling anchor cylinder.
The utility model has the beneficial effects that：
(1) the utility model is equipped with the first negative pressure cavity, the second negative pressure cavity and third negative pressure cavity, can continue to generate negative pressure ring
Border makes sea-anchor continue to sink, and increases the vertical bearing capacity and withdrawal resistance of sea-anchor.
(2) the utility model is equipped with the first anchor fluke, can improve the balance of sea-anchor, mitigates and shakes；When the first negative pressure cavity
When full of seawater, boss is located above first partition, and the first anchor fluke is attached on anchor cylinder and anchor core at this time, not will produce resistance；
When taking out water and air generation subnormal ambient by the first negative pressure cavity of first through hole pair, anchor core is moved upwards relative to anchor cylinder, the
One anchor fluke is propped up under the action of supporting rod, is firmly grabbed and is invested seabed, and firm combine is formed.
