Problems solved by technology
However, due to the hard geology of the sandy and gravel seabed, the superficial embedding of the anchor claw cannot meet the positioning requirements of the ship, and the participation of the anchor stem is required to form the embedding conditions of the main body, increase the anchoring force, and improve the anchoring ability.

Embodiment Construction
[0013] The present invention will be further described below according to accompanying drawing.
[0014] As shown in the accompanying drawings, the anchor with a toothed edge structure is composed of a left side plate 1 and a right side plate 3 connected in a figure-eight arrangement by a plurality of transverse ribs 2 . The left side plate 1 and the right side plate 3 are all provided with an outward notch, the notch is provided with a pin hole 4, and the bottom is provided with three positioning holes 5, and the positioning holes 5 are distributed in an arc centered on the pin hole 4. superior. The left side plate 1 and the right side plate 3 are provided with a set of tooth edge structures with an angle of α1 triangular teeth in the middle section of the gap. In this embodiment, the angle α1 of the triangular teeth is 70°, and the tooth edges are opposite to the pin hole 4 and figure 2 The angle between the connecting line of the leftmost positioning hole 5 shown is 32°±2...

The invention discloses a high holding power anchor shaft with tooth edge structures. The high holding power anchor shaft with the tooth edge structures comprises a left side plate and a right side plate which are connected through a plurality of transverse ribs. An outward notch is formed at the lower end of the left side plate and the lower end of the right side plate respectively, a pin hole is formed on the upper edge of the notch, and three positioning holes which are all distributed on a circular arc taking the pin hole as a center are formed on the lower edge of the notch. One tooth edge structure formed by a group of triangle teeth with angles of 70 degrees to 80 degrees is arranged in the middle sections of the notches on the left side plate and the right side plate respectively. The included angles formed by the connecting line of each tooth edge and pin hole and the connecting lines of the tooth edge and each of the three positioning hole are respectively 32 plus or minus 2 degrees, 40 plus or minus 2 degrees, and 50 plus or minus 2 degrees. In each tooth edge structure of the invention, embedment conditions for the anchor shaft and an anchor position are increased remarkably, anchoring force to a layer of hard subsoil is increased, the anchor positioning capability is enhanced, and the anchor positioning of a ship can be achieved at different geologic seal bottoms.
Description
technical field [0001] The invention relates to an anchor stem structure, in particular to an anchor stem with a tooth edge structure and a large gripping force. Background technique [0002] The main components of the deepwater high-holding anchor are the anchor stem and the anchor fluke, and the anchor stem structure has a great influence on the anchor performance. The anchor stem is a frame-shaped structure and a plowshare shape, which is composed of a plurality of transverse ribs connecting the left and right side plates arranged in a figure-eight shape. In the prior art, the left and right side plates of the anchor stem are straight sides opposite to the anchor fluke, and the anchor stem has no convex structure to be embedded with the anchor position. For soft or neutral geological seabeds, the deep-water high-holding anchor can meet the ship positioning requirements as long as the anchor fluke is embedded. For the sandy and gravel seabed, due to the hard geology, the...
