Technical Field
[0001] This utility model relates to the field of offshore wind power engineering technology, and in particular to a sealing device for grouting connection section of offshore wind power. Background Technology
[0002] Offshore wind power is a form of renewable energy that utilizes ocean wind power. It has the advantages of high power generation efficiency and abundant resources, and plays an important role in the global energy transition. The grouting connection section sealing device is derived from the offshore wind power structure. It is used to connect the wind turbine foundation and the tower. The grouting material is used to achieve sealing and fixation, prevent corrosion and leakage, and ensure long-term safe operation.
[0003] Traditional offshore wind turbine grouting connection section sealing devices operate by filling and solidifying grouting material inside the connection section to form a sealing barrier, effectively preventing seawater from intruding into the structure. However, this traditional device has significant drawbacks: its sealing performance is greatly affected by material aging, its long-term stability is insufficient, and leakage problems may occur. Existing offshore wind turbine grouting connection section sealing devices borrow the operating principle of traditional methods but employ more advanced grouting technology and materials to improve sealing efficiency and reliability. However, the current design lacks a key sealing reinforcement mechanism. This deficiency allows the device to be directly corroded by seawater in the marine environment, leading to material degradation and structural damage, thus significantly reducing its service life. In actual use, the above-mentioned devices suffer from unsustainable sealing effects, accelerated corrosion, and increased maintenance requirements. Therefore, a new offshore wind turbine grouting connection section sealing device is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1-4 An embodiment of this utility model is provided: a sealing device for a grouting connection section of offshore wind power, including an upper shell 1, a sealing mechanism 3 provided on the outer wall of the upper shell 1, a lower shell 2 fixedly connected to the bottom of the outer wall of the upper shell 1, and a stabilizing mechanism 4 provided on the outer wall of the lower shell 2.
[0033] The sealing mechanism 3 includes a grouting port 302, the outer wall of which is fixedly connected to the outer wall of the upper shell 1. The outer wall of the upper shell 1 has a grouting groove 301 and a chamber 303, which serves as a temporary storage area for the grout. The grout will subsequently permeate along the sealing groove 3081 to the sealing ring 3082. After curing, the overall strength of the base will be further improved. A first electrode plate 304 is fixedly connected to the top of the outer wall of the upper shell 1. A pole post 305 is fixedly connected to the bottom of the outer wall of the first electrode plate 304. A second electrode plate 306 is fixedly connected to the bottom of the outer wall of the pole post 305. A sealing component 308 is provided on the inner wall of the upper shell 1. The first electrode plate 304, pole post 305, and second electrode plate 306 work together to provide cathodic protection for the entire connection section. Even if the coating has extremely minor damage, it will preferentially corrode. The anode block actively protects the main structure from electrochemical corrosion and microbial-induced corrosion. The sealing component 308 includes a sealing ring 3082, the outer wall of which is fixedly connected to the top of the outer wall of the lower shell 2. A sealing groove 3081 is provided at the bottom of the outer wall of the upper shell 1. The outer wall of the upper shell 1 is provided with a reinforcing component 307, which includes a horizontal column 3071, the outer wall of which is fixedly connected to the inner wall of the pole column 305. A ring 3072 is fixedly connected to the outer wall of the horizontal column 3071, and a column 3073 is fixedly connected to the outer wall of the ring 3072. The horizontal column 3071, the ring 3072 and the column 3073 work together to fix the upper shell 1 and the lower shell 2. The entire mechanism improves the strength of the sealing structure of the grouting connection section of the wind power device.
[0034] Specifically, grouting is performed through grouting port 302. The grout first enters chamber 303 for temporary storage, then gradually seeps into sealing groove 3081 and wraps around sealing ring 3082. After curing, it effectively improves the overall structural strength of the base. In terms of protection, electrode plate one 304, electrode column 305 and electrode plate two 306 work together to provide cathodic protection. This mechanism can preferentially corrode the anode part when the coating is damaged to the smallest extent, thereby actively inhibiting the erosion of the main structure by electrochemical corrosion and microbial corrosion. In order to further improve the sealing and connection reliability, a reinforcement unit composed of horizontal column 3071, ring 3072 and vertical column 3073 is set in the structure. These units work together to enhance the bonding stability between upper shell 1 and lower shell 2. Overall, this mechanism significantly improves the sealing performance and structural durability of the grouting connection section of the wind power device through the multiple effects of grouting reinforcement, electrochemical protection and mechanical reinforcement.
[0035] Reference Figures 1-5The stabilizing mechanism 4 includes a frustum 401, which is used to reinforce the three fixing locks 402 at the bottom to ensure the stability of the device operation. The outer wall of the frustum 401 is fixedly connected to the outer wall of the lower shell 2. The fixing lock 402 is fixedly connected to the outer wall of the frustum 401. The fixing block 403 is fixedly connected to the outer wall of the fixing lock 402. The sinker 404 is fixedly connected to the outer wall of the fixing block 403. The bottom cone 405 is fixedly connected to the outer wall of the sinker 404. The sinker 404 and the bottom cone 405 cooperate with each other and can sink to the bottom by their own gravity to fix the bottom. The stabilizing mechanism 4 also includes flexible ceramic powder 406. The flexible ceramic powder 406 provides excellent wear resistance and comprehensive anti-corrosion protection, completely isolating seawater from contact with the base metal. The inner wall of the flexible ceramic powder 406 is fixedly connected to the inner wall of the upper shell 1. The inner wall of the flexible ceramic powder 406 is fixedly connected to an aluminum bronze coating 407. Its micro-elasticity can compensate for the slight deformation under extreme conditions. The whole structure improves the stability of the wind power device.
[0036] Specifically, the truncated cone 401 reinforces multiple fixing locks 402 to improve overall operational stability. The fixing locks 402 are sequentially connected to the fixing block 403, the sinker 404, and the bottom cone 405. The sinker 404 and the bottom cone 405 sink to the bottom by gravity, thus reliably fixing the bottom position. The mechanism also includes flexible ceramic powder 406, which is attached to the surface of the structure to provide comprehensive wear resistance and corrosion resistance, effectively isolating the metal substrate from seawater erosion. The aluminum bronze coating 407 has micro-elastic properties, which can compensate for the slight deformation of the structure under extreme environments. The entire structure significantly enhances the long-term stability of the wind power device through the synergistic effect of mechanical fixing and material protection.
[0037] Reference Figures 1-3 A tower 5 is fixedly connected to the top of the outer wall of the upper shell 1, which supports the nacelle 6 and the wind turbine 7, raising them to a high altitude to capture stronger and more stable wind energy. The interior is equipped with ladders and platforms for maintenance personnel to inspect and repair. The nacelle 6 is fixedly connected to the top of the outer wall of the tower 5. It is a huge shell that encloses and protects key components from the erosion of severe weather. The wind turbine 7 is rotatably connected to the front of the outer wall of the nacelle 6. It is the starting point for capturing wind energy. The blades are designed with an aerodynamic shape. When the wind blows, it generates lift, which drives the entire wind turbine 7 to rotate, converting wind energy into mechanical energy. A mounting frame 8 is fixedly connected to the top of the outer wall of the nacelle 6. A warning light 9 is fixedly connected to the outer wall of the nacelle 6, which emits visual warning signals to the outside to ensure safety. A sensor 10 is fixedly connected to the outer wall of the nacelle 6, which collects information to provide a basis for control decisions.
[0038] Specifically, the tower 5 is installed above the upper shell 1 to support the nacelle 6 and the wind turbine 7, raising them to achieve efficient capture of stable wind energy at high altitudes. The tower 5 is equipped with ladders and platforms inside for easy access and maintenance by maintenance personnel. The nacelle 6, as the main shell, protects the critical equipment inside and effectively isolates it from the harsh external environment. The wind turbine 7 generates lift under the action of wind through its aerodynamic blades, which then rotate and convert wind energy into mechanical energy. The mounting frame 8 provides additional support, the warning light 9 emits visual safety signals, and the sensor 10 continuously collects operating information to provide a data foundation for structural monitoring and control, jointly ensuring the stable operation of the unit.
[0039] Working principle: First, grout is injected through grouting port 302. The grout is temporarily stored in chamber 303 and then gradually penetrates into the sealing groove 3081 and sealing ring 3082 area. After curing, it effectively improves the overall structural strength of the base. Electrode 1 304, electrode post 305 and electrode 2 306 work together to provide continuous cathodic protection for the structure and actively resist electrochemical corrosion and microbial corrosion. Sealing component 308 ensures that the connection interface is in a sealed state. Reinforcing component 307 enhances the connection stability between upper shell 1 and lower shell 2 with the synergistic effect of horizontal column 3071, ring 3072 and vertical column 3073.
[0040] Furthermore, the truncated cone 401 reinforces multiple fixing locks 402, significantly improving the overall stability of the device. The sinker 404 and the bottom cone 405 sink autonomously with the help of gravity, reliably fixing the bottom structure. Flexible ceramic powder 406 covers the surface of the structure, providing comprehensive anti-corrosion and wear-resistant protection, completely isolating the contact corrosion of seawater to the base metal. The aluminum bronze coating 407 has micro-elastic properties, which can compensate for minor deformation of the structure under extreme conditions. The entire stabilizing mechanism 4 enhances the overturning resistance of the wind power device through the coordinated work of its components.
