Description

Submersible deep sea anchoring equipment Technical Field The utility model belongs to the field of ocean equipment, relates to anchoring equipment, and in particular relates to submersible deep sea anchoring equipment. Background The current anchoring technology is widely applied to ocean platforms, floating wind power facilities, ocean cultivation and other offshore engineering projects, and is mainly divided into two major categories of floating anchoring and deep water anchoring. Floating mooring systems, such as buoy systems and floating platforms, are commonly used in shallower waters, where they are floated on the sea surface by buoyancy maintenance devices and secured to the sea bed using anchor chains or cables. The system is more common, is suitable for facilities in shallow sea areas or middle and deep water areas, and has simple structure and easy maintenance. The deep sea anchoring system is not only applied to the traditional offshore oil and gas drilling and production platform, but also widely applied to a floating wind power plant, an ocean research platform, an ocean observation station and the like. With the continuous development of deep sea resources by human beings, the deep sea anchoring technology becomes a research focus. The deep sea anchoring system is not only applied to the traditional offshore oil and gas drilling and production platform, but also widely applied to a floating wind power plant, an ocean research platform, an ocean observation station and the like. The key components and design points of the deep sea anchoring technology comprise an anchoring system, an anchor chain design, a floating stabilizer, a surge power generation and autonomous power supply system, and the deep sea anchoring mode of the anchoring system generally comprises a towing anchor, a suction anchor, a gravity anchor, a pile anchor and the like. The deep sea anchoring system needs to be selected according to the sea conditions (such as sediment, rock) and has sufficient tensile strength and durability to ensure that a stable anchoring effect is provided under severe deep sea conditions. The design of the anchor chain is particularly important for the design of the anchor chain in a deep sea mooring system. Conventional steel anchor chains are widely used in deep sea environments due to their weight and corrosion resistance. In recent years, synthetic fiber cables (such as ultra-high molecular weight polyethylene cables) are increasingly used in deep sea mooring systems, and have the advantages of light weight, high strength, fatigue resistance and corrosion resistance. For floating stabilizers, the deep sea mooring facility may be suspended in the water, equipped with a special floating stabilizer system. These devices maintain the device at a predetermined depth through buoyancy tanks or floating structures, ensuring accuracy of data acquisition and monitoring. For both surge generation and autonomous power supply systems, power supply is a challenge since deep sea mooring equipment is typically far off shore. Therefore, many deep sea mooring equipment is equipped with a surge power generation system or other form of autonomous power supply device that utilizes ocean wave kinetic energy or ocean current energy to power the equipment. In the prior art, the form of the anchoring equipment floats on the water surface, the stability of the anchoring equipment is maintained by depending on buoyancy and an anchor chain, the anchoring equipment is easily influenced by ocean surface storms and tides, drifting or swinging is caused, and the stability of the equipment and the accuracy of data acquisition can be influenced particularly under severe weather conditions. Floating mooring systems are commonly used in shallow to medium water depths. In a deep sea environment, as the water depth increases, the anchor chain or cable length increases significantly, the complexity and cost of the system increases substantially, with the risk of abrasion or breakage caused by contact friction of the anchor chain with the seabed. Long-term, accurate monitoring in a deep sea environment requires that the equipment be able to operate stably at a predetermined depth under water, rather than relying on a buoyancy system on the sea surface. Most current floating devices cannot achieve the aim, particularly in ultra-deep water areas, the stability and the efficiency of an anchoring system are seriously affected, and the requirements of deep sea data acquisition and long-term observation are difficult to meet. Some critical marine observation and research tasks cannot be accomplished by conventional floatation devices, especially in the field of dynamic monitoring inside the ocean and deep sea environmental data acquisition. Such as tsunami dynamics, deep ocean currents, pressure fluctuations, ocean temperature variations, and observations of the ocean's internal ecosystem, require that the sensing devices located underwater p
