Description

linkage mooring device

technical field

The utility model relates to a main body device for mooring a net cage in deep water, in particular to a linked mooring device.

Background technique

Mooring systems are crucial to the safety and stability of moored objects. The reliability of the mooring system of the deep-water aquaculture cage is the key to ensure its normal and safe operation at the designated location. Traditional anchors such as high holding power anchors rely on the anchor chain and the weight of the anchor to provide resilience and limit the movement of the moored object. However, if the anchor chain is not long enough and the anchor does not have enough weight when encountering strong winds or waves, resulting in insufficient anchoring force, anchor walking will occur, endangering the normal operation of the moored object and the safety of its surrounding environment. With the rapid development of my country's ocean engineering, it is urgent to find a more reasonable new mooring system. The Chinese patent application number is: 200810038546.0, and the patent name is: Dynamic Embedded Anchor with High Frequency Micro-amplitude Vibration. The patent includes: anchor head, anchor rod, anchor wing, anchor chain, built-in motor, and motor cable. During the anchor deployment process, the motor is started, and the anchor body liquefies the surrounding bed sand under the high-frequency and slight vibration of the motor, and the anchor is quickly buried in the soil by its own weight and the exciting force of the motor. Its main disadvantage is that for a permanent mooring system, when the anchor is installed, the motor has to stay in the anchor body, which is expensive. Therefore, it is necessary to develop new anchors that are more practical and cost-effective.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: a linkage mooring device, including two anchor bodies with high fixation strength connected by a cable, wherein: a sliding holder is provided for the upper movement of the cable; the sliding holder has a traction frame, and the traction frame is provided with a main pulley and a secondary pulley; the main pulley and the secondary pulley of the sliding holder can clamp the cable in the pulley groove of the main pulley. The sliding holder can slide freely on the cable connected between two anchor bodies with high fixing strength; and, the end of the traction frame away from the main pulley has a connecting buckle, through which the rope is connected, and then connected to the cage, aquaculture Rafts, floating fish reefs; the back and forth sliding of the sliding holder can reduce the horizontal elevation angle of the cable, thereby preventing the lateral movement of the anchor body and playing the role of anti-flow. the

In order to optimize the above-mentioned technical scheme, the measures taken also include: a sliding retainer is provided for the upper motion of the cable; the sliding retainer has a traction frame, and the traction frame is provided with a master pulley and a slave pulley; The pulleys hold the cable in the pulley grooves of the main pulley. The sliding holder can slide freely on the cable connected between two anchor bodies with high fixing strength; and, the end of the traction frame away from the main pulley has a connecting buckle, through which the rope is connected, and then connected to the cage, aquaculture Rafts, floating fish reefs; the back and forth sliding of the sliding holder can reduce the horizontal elevation angle of the cable, thereby preventing the lateral movement of the anchor body and playing the role of anti-flow. The anchor body with high fixation strength includes cement piers arranged in an array; the upper part of the cement piers is connected with a rigid support; the bottom of the cement piers has a concave surface and forms a semi-open inner cavity; Connected prefabricated vias. The self-weight of the cement pier makes the whole structure tightly attached to the seabed under the action of gravity, and the water in the semi-open inner cavity of the inner concave surface at the bottom of the cement pier is slowly discharged through the prefabricated through holes, so that the sediment on the seabed can Quickly fills the inner concave surface, can generate greater negative pressure when subjected to instantaneous pulling, and has better stability. Due to the small diameter of the prefabricated through holes, the efficiency of generating negative pressure will not be affected when instantaneous traction occurs. Rolls of barbed wire are provided inside the prefabricated through-holes. The mesh of barbed wire is 40 to 90. Because it is flexible, it can be rolled into strips and stuffed into the hollow tube. It has a short-term air permeability function. Due to the erosion of seawater and the attachment of organisms, its air permeability will decrease rapidly, and the hollow tube will be blocked soon, so that the inner concave surface where the sediment accumulates is isolated from the external water pressure. When the cement pier encounters an upward pulling force, negative pressure is formed on the inner concave surface, and the fixing effect is quite good. The inner concave surface is an ellipsoid, a sphere or an arc. While the above-mentioned better traction in the vertical direction can be formed, due to the indentation, its secondary effect is to save materials and have a better cost-effectiveness ratio. A hollow tube is arranged in the prefabricated through hole. The material of the hollow tube is metal. The role of using metal is also to quickly achieve corrosion, promote the rapid accumulation of algae, microorganisms, and attached organisms, and block the prefabricated through-holes to achieve the effect of connecting the inside and outside in the early stage, and the effect of negative pressure in the later stage. The hollow pipe is selected from galvanized pipe and iron pipe. The rigid bracket has an attachment ring; a connector is attached to the attachment ring.

Because the utility model adopts the upper movement of the cable and is equipped with a sliding holder; the sliding holder has a traction frame, and the traction frame is provided with a master pulley and a slave pulley; the master pulley and the slave pulley of the slide holder can clamp the cable In the pulley groove of the main pulley. The sliding holder can slide freely on the cable connected between two anchor bodies with high fixing strength; and, the end of the traction frame away from the main pulley has a connecting buckle, through which the rope is connected, and then connected to the cage, aquaculture Rafts, floating fish reefs; the back and forth sliding of the sliding holder can reduce the horizontal elevation angle of the cable, thereby preventing the lateral movement of the anchor body and playing the role of anti-flow. Therefore, the utility model has the advantages of strong adsorption force, simple manufacture, quick construction, lower cost, good anchoring effect, strong wind and wave resistance, and good anchor resistance effect.
