[0002] Sealing is one of the key components of engineering equipment, which ensures the good barrier of sealed medium and non-sealed medium. In recent years, with the rapid development of wind power industry, the sealing used for wind turbine also gradually develops, especially the sealing used for jacket develops rapidly. With the requirement of wind turbine developing towards larger megawatt level power generation, the requirement of jacket is also higher and higher. In order to ensure the stability of jacket in the sea, offshore piling technology emerges as the times require. The connection between jacket and pile is generally realized by grouting. However, grouting material is a material with good flow performance, and the grouting material needs a certain time to solidify. Therefore, the sealing ring is generally used for sealing. The sealing ring is generally pre-installed on the jacket on the shore or wharf.

[0003] Since the offshore wind turbine is constructed in a relatively harsh environment, the sealing effect of grouting sealing affects the construction period and the use amount of grouting in the construction process. In order to save expensive grouting material and ensure the smooth development of construction, the research on grouting sealing ring is carried out. The grouting sealing ring for offshore wind power pile construction is designed to solve the problems of grouting leakage and bearing during grouting. SUMMARY

[0006] Further, the rubber block includes an upper rubber layer, a reinforcing layer and a lower rubber layer.

[0007] Still further, the reinforcing layer adopts high-strength canvas cloth.

[0008] Still further, the canvas cloth includes radially distributed canvas threads and circumferentially distributed canvas threads, wherein the radially distributed canvas threads adopt a dense distribution structure, and the circumferentially distributed canvas threads adopt a sparse distribution structure.

[0009] Furthermore, the reinforcement layer is provided with one or at least two layers.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) The structural cross section of this utility model can cover a variety of structural forms. Depending on the actual load-bearing capacity and requirements of the product, the load-bearing problem of the product can be solved by using one or more reinforcing layers.

[0015] (2) This utility model can achieve reinforcement of different regions and different degrees by adjusting the distribution of the reinforcement layers. When using multiple reinforcement layers, they can be distributed in a concentrated manner or in layers, which can be adjusted according to the usage requirements.

[0016] (3) The reinforcing layer of this utility model is a segmented filling reinforcing layer structure, and the cost of processing and manufacturing the reinforcing layer structure is relatively low.

Detailed Implementation

[0027] 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.

[0028] Figure 1 The entire jacket pile is shown, in which the sealing ring 4 is located between the jacket pile leg 1 and the steel pile 3, and is used to seal the cement grout from the grouting pipe 2 and the seawater at the bottom. The tip end 5, the reinforcing rib 6 and the tip front section 7 form the tip, which is used to guide the sealing ring 4 during installation and can also prevent seabed silt from entering the jacket pile leg.

[0029] like Figure 2 A segmented offshore wind turbine pile grouting sealing ring structure includes a sealing ring 4. The sealing ring 4 adopts a segmented structure, which is composed of multiple rubber blocks connected in a ring. The sealing ring 4 after the rubber blocks are connected in a ring includes an installation part and a sealing part. The installation part is fixed to the pile leg 1 of the guide frame by a locking mechanism. The sealing part extends outward along the upper part of the installation part in all directions.

[0030] In this embodiment, the seal is installed on the guide frame pile leg 1 by a locking mechanism consisting of a circumferentially distributed pressure plate 10, bolts 11, nuts 12, and washers 13. By adjusting the tightening torque of the bolts 11, the rubber at the mounting handle is compressed and deformed, forming the lower seal. The upper seal is formed by the tight fit between the lip of the product and the steel pile 3. The seal between the sealing lip and the steel pile 3 is achieved due to sufficient interference fit between the seal and the pile, ensuring the seal of the product. At the same time, the sufficient interference fit also allows the seal to bear the weight of the upper mud.

[0031] The sealing ring 4 includes an upper rubber layer 8-1, a reinforcing layer 9, and a lower rubber layer 8-2. The upper rubber layer 8-1 is in contact with the cement slurry on its upper surface. The reinforcing layer 9 is made of high-strength cord fabric, and the structure of the cord fabric is as follows: Figure 3 As shown, its characteristics are that the radial cords 15 are densely distributed, which plays a role in reinforcing the product when it is deformed under load, while the circumferential cords 14 are sparsely distributed, which mainly plays a role in preventing the radial cords 14 from being dispersed. By adjusting the material and number of reinforcing layers, different load-bearing capacities of the product can be achieved; the lower rubber layer 8-2 is in contact with seawater and also plays a role in sealing the lip.

[0032] Figure 4 The sealing ring shown is composed of multiple identical sealing segments, where each segment from a1 to an is a standard rubber block containing a rubber layer and a reinforcing layer. The bonding area 17 between any two adjacent segments is either a pure rubber structure or a pure rubber structure with a reinforcing mesh. The cross-sections of the two structures are shown below. Figure 5 As shown, by adjusting the number of reinforcing mesh layers distributed within the pure adhesive, the dimensional stability and bonding strength at the interface can be improved.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit the scope of protection of this utility model in any way, and all technical solutions obtained by equivalent substitution or other means fall within the scope of protection of this utility model. Parts not covered by this utility model are the same as or can be implemented using existing technology.
