Abstract
Description
Technical Field
[0001] This utility model relates to the field of offshore wind power engineering technology, and in particular to a jacket positioning device. Background Technology
[0002] Offshore engineering is characterized by harsh working conditions, significant susceptibility to natural elements, short working hours, and considerable construction challenges due to its location at sea. Jacket structures are one of the most commonly used foundation structures in marine engineering. Their advantages, such as high overall rigidity, low wave force, and minimal structural deformation, make them suitable for various water depths, leading to their widespread application in offshore oil and offshore wind power.
[0003] These jacket structures are installed on the seabed to support and protect pipelines, ensuring their safe and reliable operation in the marine environment. The jackets are typically fixed to the seabed by steel piles. They are prefabricated on land, transported to the sea, and then piles are driven along the duct. Finally, cement grout is poured into the annular gap between the piles and the duct, connecting them to the seabed and securing them as a single unit. Due to the unique nature of offshore construction, the jackets are inevitably subjected to wave action during installation. Without pre-positioning the foundation, the waves will cause the jackets to tilt laterally, making positioning impossible and hindering subsequent installation. Utility Model Content
[0004] In view of this, the present invention aims to provide a catheter stent positioning device to solve the above problems.
[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0006] A jacket positioning device includes a collar, a connecting rod, a fixing cone, a fixing post, a lower flange, and a guide post. The collar is fixed to the top of the fixing post, which is inserted into the ground. Several vertically arranged fixing cones are provided on the outer periphery of the collar, and the fixing cones are also inserted into the ground. Each leg of the jacket is connected to a post below it. The number of collars is equal to the number of posts. The posts are inserted into the corresponding collars. Several collars are connected as a whole by the connecting rod. The top of the collar is provided with a lower flange, and the outer periphery of the posts is provided with an upper flange. The edge of the lower flange is provided with a vertically arranged guide post, and the edge of the upper flange is provided with a C-shaped limiting notch that fits onto the guide post.
[0007] Furthermore, pulleys are provided on the side wall of the collar, and fixed rings are provided on the legs of the guide frame. One end of the pull rope is fixed to the fixed ring, and the other end of the pull rope passes around the pulley and extends out of the water surface. After passing around the lifting pulley on the shore or the work boat, it is connected to the winch.
[0008] Furthermore, a counterweight is also provided on the connecting rod.
[0009] Furthermore, a vertically installed screw is fixed on the lower flange, and the guide post is screwed to the screw.
[0010] Furthermore, the length of the fixed pile is greater than the length of the fixed cone.
[0011] Compared with the prior art, the catheter stent positioning device of this utility model has the following advantages:
[0012] The jacket positioning device of this utility model includes a collar, a connecting rod, a fixing cone, a fixing pile, a lower flange, and a guide post. The fixing pile and fixing cone are inserted into the ground to improve the anchoring effect. The guide post is provided on the lower flange. During the descent of the jacket, the limiting notch is aligned with the guide post. When the limiting notch is fitted onto the guide post, the jacket can move down along the guide post. The guide post guides the downward movement of the jacket. At the same time, since the guide post is rigid, it can prevent the jacket from tilting and shifting under the impact of waves, which facilitates the installation of the jacket.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0022] like Figure 1-2 As shown, a jacket positioning device includes a collar 2, a connecting rod 3, a fixing cone 4, a fixing post 9, a lower flange 10, and a guide post 11. The collar 2 is fixed to the top of the fixing post 9, which is inserted into the ground. Several vertically arranged fixing cones 4 are provided on the outer periphery of the collar 2, and the fixing cones 4 are also inserted into the ground. Each leg of the jacket 1 is connected to a post 14. The number of collars 2 is equal to the number of posts 14. The posts 14 are inserted into the corresponding collars 2. Several collars 2 are connected to each other as a whole by the connecting rod 3. The top of the collar 2 is provided with a lower flange 10. The outer periphery of the post 14 is provided with an upper flange 12. The edge of the lower flange 10 is provided with a vertically arranged guide post 11. The edge of the upper flange 12 is provided with a C-shaped limiting notch 13 that fits on the guide post 11.
[0023] Fixed piles and fixed cones are inserted into the ground to improve the anchoring effect. Guide posts are installed on the lower flange. During the descent of the jacket, the limiting notch on the upper flange aligns with the guide post. When the limiting notch fits onto the guide post, the jacket moves downward along the guide post. The guide post guides the downward movement of the jacket. Simultaneously, because the guide post is rigid, it prevents the jacket from tilting or shifting under the impact of waves, facilitating the installation of the jacket. Finally, the legs at the bottom of the jacket are inserted into the corresponding collars, and the upper and lower flanges are then fixed with bolts, thus achieving the positioning and installation of the jacket.
[0024] For example, a pulley 6 is provided on the side wall of the collar 2, and a fixed ring 8 is provided on the support leg of the guide frame 1. One end of the pull rope 7 is fixed to the fixed ring 8, and the other end of the pull rope 7 passes around the pulley 6 and extends out of the water surface. After passing around the lifting pulley 156 on the shore or the work boat, it is connected to the winch.
[0025] When the water level is deep, pulleys and ropes can be used to control the position of the jacket in the early stage of its descent, preventing it from shifting too much. When the jacket descends to the guide post, the guide post is used for positioning.
[0026] For example, the connecting rod 3 is also provided with a counterweight 5.
[0027] For example, a vertically arranged threaded rod is also fixed on the lower flange 10, and the guide post 11 is threaded to the threaded rod. The threaded connection facilitates the disassembly and recycling of the guide post.
[0028] For example, the length of the fixed pile 9 is greater than the length of the fixed cone 4. The fixed pile provides the main anchoring and extends deeper into the ground, while the fixed cone provides auxiliary anchoring.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
