Abstract

The utility model provides a be equipped with additional anchor body and additional anchor body can expand torpedo anchor of turning up. The torpedo anchor mainly comprises an anchor body, anchor wings, an additional anchor body, a fixed hinge, an anchor head and the like. The additional anchor body is four in number, and the whole anchor body is cylindrical when not unfolded. Wherein, the additional anchor body is far away from the anchor head end and is the horn mouth form, and the other end links together through fixed hinge with the anchor body. The surface of the anchor body is flat, and the whole shape of the anchor body is close to that of a common torpedo anchor. The new torpedo anchor proposed herein is the same as a conventional torpedo anchor when it is inserted into the sea floor, with the additional anchor body fitting tightly against the body of the anchor body. However, when the torpedo anchor is under tension, because the force acting on the additional anchor body generates moment on the fixed hinge at the anchor head, the additional anchor body is unfolded and turned outwards under the action of the moment, the stress area is enlarged, and the ultimate uplift bearing capacity of the torpedo anchor is greatly improved.

Description

Torpedo anchor with additional anchor body and additional anchor body capable of being unfolded and turned outwards

Technical Field

The utility model belongs to the technical field of the anchor mooring of deep sea floating platform or deep water box with a net, a be equipped with additional anchor shaft and additional anchor shaft can expand torpedo anchor of turning up.

Background

A torpedo anchor is one type of power driven penetration anchor, typically about 15m in length and weighing up to 130 tonnes. The torpedo anchor is named because the shape of the torpedo anchor is exactly like a torpedo, and comprises a cylindrical anchor body, a bullet-shaped or conical anchor head and anchor wings arranged at the tail of the anchor body. The anchor body is a thick-wall hollow steel pipe, concrete and waste metal are filled in the anchor body, the gravity center of the anchor body is adjusted while the whole weight of the anchor is increased, the gravity center is deviated to the anchor head, the direction stability during falling is enhanced, and the lower end part is in a conical shape and is convenient to penetrate into a seabed soil body. The fish-thunder anchor is simple in installation and operation, free-falling only by means of gravity and free-falling without any launching device, and theoretically suitable for any water depth. Firstly, the torpedo anchor is transported to a designated installation position by an anchor throwing ship, the torpedo anchor is vertically suspended 20-75 meters away from the surface of the seabed, and then the torpedo anchor is released to freely fall, so that the torpedo anchor is penetrated into the seabed, and the installation is completed.

SUMMERY OF THE UTILITY MODEL

The utility model provides a be equipped with additional anchor body and additional anchor body can follow the torpedo anchor that the anchor body main part expandes to turn up, improve greatly than traditional torpedo anchor limit resistance to plucking bearing capacity. The additional anchor body part of the torpedo anchor is unfolded and turned outwards when the torpedo anchor is under tension, so that the uplift resistance area of the torpedo anchor is enlarged, and the ultimate uplift resistance bearing capacity of the torpedo anchor is improved.

The technical scheme of the utility model:

a fish-thunder anchor provided with an additional anchor body and capable of being unfolded and turned outwards mainly comprises an anchor body main body 1, anchor wings 2, an additional anchor body 3, a fixed hinge 4 and an anchor head 5; wherein, the additional anchor body 3 is connected with the anchor body main body 1 through a fixed hinge 4 arranged at the anchor head 5; the additional anchor body 3 is composed of four blocks, each block is the same and is in a quarter ring shape and is attached to the periphery of the anchor body main body 1; the additional anchor body 3 has a flat surface, and the whole shape is close to the shape of the torpedo anchor. When the novel torpedo anchor is used, the novel torpedo anchor is the same as a common torpedo anchor when being penetrated into the sea bottom, and the additional anchor body is tightly attached to the anchor body main body. However, when the torpedo anchor is pulled, the reaction force of the seabed sludge on the additional anchor body can generate moment on the fixed hinge of the anchor head part, the additional anchor body is unfolded and turned outwards under the action of the moment, the stress area is enlarged, and the ultimate uplift bearing capacity of the torpedo anchor is greatly improved. The utility model discloses an advantage is that the use is simple, and is unanimous with ordinary fish thunder anchor's application method on the whole, but the big improvement of limit resistance to plucking bearing capacity.

The additional anchor body 3 is in a bell mouth shape far away from the anchor head 5, and when the torpedo anchor is pulled, the additional anchor body is easier to unfold due to the reaction force acting on the bell mouth end of the additional anchor body; under the effect of external moment, additional anchor body 3 on 4 upper portions of fixed hinge is outwards rotated and is expanded around 4 fixed hinges, additional anchor body 3 on 4 lower portions of fixed hinge is towards anchor body main part 1 inside rotation, anchor body main part 1 is equipped with the recess above anchor head 5, additional anchor body 3 on 4 lower portions of fixed hinge is rotatory and unrestricted in the spatial dimension of recess, after additional anchor body 3 is rotatory to certain angle, 3 inner walls of additional anchor body on 4 lower portions of fixed hinge are blocked by the recess upper wall that sets up on anchor body main part 1, thereby whole additional anchor body 3 is fixed, thereby the resistance to plucking area increase of fish and thunder anchor.

The utility model discloses an effect and benefit: when the conventional torpedo anchor meets the condition of low strength of seabed soil body in the use process, the uplift bearing capacity of the conventional torpedo anchor can not meet the use requirement. This novel torpedo anchor can effectively improve limit resistance to plucking bearing capacity, creatively sets up additional anchor body and is connected additional anchor body and anchor body main part through the fixed hinge around the anchor body main part, and when torpedo anchor received the pulling force, seabed silt can make additional anchor body expand around the fixed hinge and turn up for the reaction force of additional anchor body, has increased the resistance to plucking area greatly to the limit resistance to plucking bearing capacity of torpedo anchor has been improved. The use method of the novel fish-stone anchor is as simple and convenient as that of the traditional fish-stone anchor.

Detailed Description

The following describes the embodiments of the present invention with reference to the attached drawings:

a torpedo anchor with an additional anchor body and an expandable and evertable additional anchor body comprises an anchor body main body 1, anchor wings 2, an additional anchor body 3, a fixed hinge 4, an anchor head 5 and the like. The anchor wing 2 of the torpedo anchor is connected with the anchor body main body 1, the anchor head 5 of the torpedo anchor is connected with the anchor body main body 1, the anchor body main body 1 and the additional anchor body 3 are divided into two parts, and the two parts are connected through the fixing hinge 4 close to the anchor head. The additional anchor body 3 is locked by the groove on the anchor body 1 after being turned outwards and unfolded at a certain angle through the fixing hinge 4, so that the fixation is realized, and the uplift area of the torpedo anchor is increased.

The application method of the fish-stone anchor comprises the following steps:

before releasing the torpedo anchor, the anchor body 1 and the additional anchor body 3 are attached together, and the appearance of the torpedo anchor is consistent with that of a common torpedo anchor. When the torpedo anchor penetrates into the seabed soil body to a certain depth and is under the action of a pulling force, the additional anchor body 3 is under a downward reaction force, the reaction force can form an external moment on the fixing hinge 4, the additional anchor body 3 is unfolded and turned outwards under the moment, and the drawing-resistant area of the torpedo anchor is enlarged as shown in fig. 3 and 4, so that the ultimate drawing-resistant bearing capacity of the torpedo anchor is greatly improved.
