[0027] Example

[0028] like Figure 1 - Figure 5 As shown, an eco-friendly adjustable weight intelligent gravity anchor includes: a base plate 1, which is a heavy steel structure and has a cross-shaped skirt 11 on the bottom surface. A steel box 2 is detachably connected to the top surface by a latch. The outer shell of the steel box 2 is made of composite material, which has a dense microstructure and stable chemical properties, and can effectively resist the hazards of long-term seawater erosion, strong ocean current scouring and marine microbial attachment and degradation.

[0029] The steel box 2 is a prefabricated nine-square grid structure, including a central block 3, four side blocks 4 and four corner blocks 5. The central block 3 is embedded with a counterweight block 6, which is a prefabricated concrete structure that can increase ballast capacity and improve buoyancy resistance and stability.

[0030] Each of the four corner blocks 5 is equipped with an energy storage tank 7, and the four side blocks 4 are filled with counterweights, which are materials such as waste rock and scrap iron. Each side block 4 has an opening 14 on the side wall of the corresponding steel box 2. A gate 15 is rotatably connected to the opening 14 to facilitate filling and releasing the filler. The gate 15 has a V-shaped structure that rotates up and down. The gate 15 is controlled as follows: when the gate 15 rotates upward to block the upper part of the opening 14, the lower part of the opening 14 is opened, and the filler in the side block 4 is released. Conversely, when the gate 15 rotates downward to block the lower part of the opening 14, the upper part is opened, and the counterweight can be filled. Moreover, the gate 15 itself has an incline, which can play a guiding role.

[0031] The four outer walls of the steel box 2 are all fixedly connected with brackets 12. The brackets 12 are hollow triangular prisms with a surface coated with a harmless protective material. The brackets 12 can provide stable support for the gravity anchor and also serve as artificial reefs, which helps to promote the restoration of the seabed ecosystem. They highlight the characteristics of ecological synergy and resource sustainability, effectively enhance the harmonious integration of the floating offshore wind turbine gravity anchor and the marine ecosystem, and significantly improve the comprehensive development and utilization of marine resources.

[0032] The side wall of steel box 2 can also be detachably connected to a float via a latch as needed. The float is made of rubber and has an external hook and ring assembly. The float adjusts its buoyancy by inflation and deflation mechanism. During installation at sea, the buoyancy of the structure can be changed by adjusting the air volume, which facilitates fine-tuning of the installation position, correcting offset errors, improving installation efficiency and accuracy, and ensuring the smooth progress of subsequent projects.

[0033] The top of the steel box 2 is detachably connected to a top cover 8. The top cover 8 has multiple equipment compartments 9, each of which is equipped with a sensor and an intelligent underwater robot. The sensors and intelligent underwater robots are electrically connected to the energy storage tank 7. The top surface of the top cover 8 is detachably connected to a universal lock 10 for connecting the anchor chain. The universal lock 10 has good mechanical performance and high flexibility. Its universal design allows it to freely adjust its angle and direction in three-dimensional space, accurately adapting to the mechanical transmission requirements under various complex working conditions and reducing maintenance costs.

[0034] The top cover 8 is equipped with an ecological tank 13, which is filled with beneficial microorganisms that can release specific chemical substances or form a unique ecological environment to attract marine life to inhabit and reproduce.

[0035] The working principle of this utility model can be summarized as follows:

[0036] Step 1: Precisely sink the heavy steel base plate 1 with skirt 11. The high-strength heavy steel base plate 1 with skirt 11 is precisely sunk into the predetermined position. Multiple specially designed first locks are evenly distributed on the top of the steel plate. The size and shape of the first locks are precisely calculated to ensure that they can be tightly and securely locked to the steel box 2. The design of the skirt 11 can enhance the contact stability between the base plate 1 and the seabed.

[0037] Step 2: Deploy the prefabricated nine-square steel box 2 on the shore. The steel box 2 is secured with sturdy rubber buoys made of strong and corrosion-resistant materials. The buoyancy of the buoys is precisely adjusted so that they can effectively counteract part of the weight during the sinking process of the steel box 2, thereby slowing down the sinking speed and allowing the steel box 2 to sink along the predetermined trajectory and speed. This greatly improves the accuracy of the deployment and ensures that the steel box 2 is accurately positioned.

[0038] Step 3: The precast concrete counterweight block 6 is smoothly sunk into the middle section of the steel box 2. Its weight and shape are designed according to the counterweight requirements of the overall structure. Next, waste rock, scrap iron, and other materials are filled into the four side sections 4 of the steel box 2. The amount and distribution of these materials can be flexibly adjusted according to actual needs, effectively increasing the flexibility of the anchor's counterweight adjustment. When the gate 15 rotates upward to block the upper part of the opening 14, the lower part of the opening 14 is opened, and the filling material in the side section 4 is released. Conversely, when the gate 15 rotates downward to block the lower part of the opening 14 while the upper part is open, counterweights can be filled. Moreover, the gate 15 itself has an incline, which can guide the material, thereby adjusting the counterweight distribution to adapt to the wind turbine load and marine conditions. It can compensate for unbalanced loads, stabilize the structural posture, reduce hidden dangers, extend service life, and improve the performance and stability of the offshore wind power system.

[0039] Four energy storage tanks 7 are placed in the four corner blocks 5 of the steel box 2. The energy storage and transmission system of the energy storage tanks 7 is optimized. The natural energy storage tanks 7 form an integrated energy conversion system, which fully develops bioenergy and seabed thermal energy to provide a stable and continuous energy supply for sensors and intelligent underwater robots.

[0040] Step 4: Accurately fasten the top cover 8 onto the top of the steel box 2. The top cover 8 and the steel box 2 are secured using a convenient snap-on fastener method. The snap-on structure allows for quick changes to the anchor weight later if needed. At the top of the top cover 8, one or more universal locking buckles 10 are flexibly installed according to engineering design requirements. The universal locking buckles 10 have multi-degree-of-freedom rotation capabilities and can be stably connected to the anchor chain. The connection between the top cover 8 and the box body adopts a special water-permeable design. This design ensures smooth seawater flow, facilitating the efficient recovery and utilization of bioenergy and thermal energy by the energy storage tank 7, thereby improving the overall energy utilization efficiency.

[0041] Step 5: Test pull. If the actual effect meets the design requirements, install hollow triangular prism support brackets 12 around the steel box 2 to make the entire structure more stable. This also allows it to serve as an artificial reef for planting aquatic plants and coral reefs, creating a habitat, aiding ecological restoration, enhancing biodiversity, and achieving a win-win situation for both ecological and engineering benefits. The surface of support bracket 12 is coated with a harmless protective material to protect the structure from corrosion and minimize the impact on organisms gathered on the artificial reef, providing them with a safe habitat.

[0042] Step 6: High-precision sensors and intelligent underwater robots are systematically arranged in the pre-reserved equipment compartment 9 of the top cover 8. The types and layout of sensors are optimized according to monitoring needs, enabling precise collection of various data such as structural stress, ocean current velocity, and ocean temperature. The intelligent underwater robot is equipped with advanced detection and communication equipment, allowing for comprehensive monitoring of the surrounding environment of the foundation structure when necessary. A digital twin model is constructed through algorithm analysis to improve the reliability and safety of the anchor structure. Simultaneously, beneficial organisms are rationally arranged in the ecological tank 13 on the top cover 8, which can release specific chemical substances or create a unique ecological environment to attract seabed organisms to inhabit and reproduce. Construction is now complete.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
