Description

Technical Field

[0001] The utility model relates to the technical field of mooring anchors for offshore oil platforms and wind power platforms, in particular to a combined deep-sea pile anchor. Background Art

[0002] As the exploration of marine resources is increasingly moving towards the deep sea, the deep-sea mooring anchoring scheme has greatly affected the installation efficiency of the mooring system. For geological areas with deep water and soft seabed soil environment, a gravity penetration mooring anchor can be used. Through free fall on the installation ship, the anchor body is driven into the seabed under the action of its own weight, thereby completing rapid mooring. The traditional form of pile anchor has a fixed structure and the overall weight and center of gravity cannot be adjusted. The anchoring of the mooring system is not the same in different areas of water depth and water flow rate. Therefore, if the mooring anchor is required to ensure sufficient kinetic energy and a stable falling posture during free fall, traditional pile anchors of different sizes must be designed according to different waters, so there is no way to mass-produce them. Summary of the invention

[0003] The utility model aims to solve the above technical problems and provide a combined deep-sea pile anchor, which has the characteristics of convenient production, adjustable deadweight and center of gravity, stable structure, etc., and can effectively solve the problems of use and mass production of the above anchors.

[0004] In order to achieve the above technical objectives and meet the above technical requirements, the technical solution adopted by the utility model is: a combined deep-sea pile anchor, characterized in that it includes an anchor body and an anchor head, the anchor body and the anchor head are connected by a fixing pin, the anchor body includes an anchor body and an anchor connecting ear, a plurality of wings are evenly distributed on the outer surface of the anchor body, an anchor head counterweight is arranged in the anchor head, an anchor end heavy counterweight is arranged at the end of the anchor body, and a plurality of anchor body light counterweights are arranged in the anchor body, and the weight and center position of the anchor body itself can be adjusted by increasing or decreasing the number of counterweights.

[0005] Preferably, the anchor body is configured as a hollow structure.

[0006] Preferably, a plug-in portion is provided at the connecting end between the anchor head and the anchor body, and the plug-in portion is inserted into the inside of the anchor body and connected to the anchor body via a fixing pin.

[0007] Preferably, the anchor head and the anchor head counterweight are configured to be conical.

[0008] Compared with the traditional structure, the utility model has the following beneficial effects: simple structure, the deep-sea pile anchor is designed as a two-section structure of the anchor body and the anchor head and connected by a fixing pin, which can ensure stable anchoring fixation, and the weight and center position of the anchor body can be adjusted by adjusting the different numbers of counterweight blocks inside the anchor body. It has the characteristics of convenient production, adjustable own weight and center of gravity, stable structure, etc., and can be mass-produced. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The utility model is further described below.

[0015] See attached Figure 1-4 A combined deep-sea pile anchor, characterized in that it includes an anchor body 1 and an anchor head 2, wherein the anchor body 1 and the anchor head 2 are connected by a fixing pin 6, the anchor body 1 includes an anchor body 11 and an anchor connection ear 13, a plurality of wings 12 are evenly distributed on the outer surface of the anchor body 11, an anchor head counterweight 3 is arranged in the anchor head 2, an anchor end heavy counterweight 4 is arranged at the end of the anchor body 11, and a plurality of anchor body light counterweights 5 are arranged in the anchor body 11.

[0016] In this preferred embodiment, the anchor body 11 is configured as a hollow structure.

[0017] In this preferred embodiment, the connecting end between the anchor head 2 and the anchor body 11 is provided with an inserting portion 21 , which is inserted into the anchor body 11 and connected to the anchor body 11 via a fixing pin 6 .

[0018] In this preferred embodiment, the anchor head 2 and the anchor head counterweight 3 are configured to be conical.

[0019] In specific implementation, the utility model is composed of an anchor body 1, an anchor head 2, a conical anchor head counterweight 3, an anchor end heavy counterweight 4, and an anchor body light counterweight 5. The anchor body 1 is welded together by an anchor body 11, a wing 12, and an anchor connection ear 13, wherein the anchor body 11 and the wing 12 are welded together into a whole by using high-strength steel plates, and are welded together with the anchor connection ear 13 cast by high-strength steel. The anchor head 2 is also cast in one piece by using high-strength steel, and the anchor body 11 is a hollow body, which can be built-in with counterweights. The weight and center position of the anchor body itself can be adjusted by adding or reducing counterweights, and the built-in counterweights can be manufactured by casting steel, cement casting, etc. After determining the anchoring water conditions, the deadweight and center of gravity requirements of the deep-sea pile anchor are confirmed by calculation, thereby confirming the number and size of the counterweights inside the anchor body 11, and after installing them into the internal cavity of the anchor body 1, the anchor head 2 and the anchor body 11 are connected by the fixing pin 6, and the fixing pin 6 and the anchor body 11 are fixedly welded, and then the junction of the anchor head 2 and the anchor body 11 is assembled by welding, and finally the overall fixed assembly of the deep-sea pile anchor is completed.
