Description

Technical Field

[0001] This utility model belongs to the technical field of wind turbine foundation jackets, and specifically relates to a wind turbine foundation jacket. Background Technology

[0002] Currently, the main types of wind turbine foundations for offshore wind power generation include: monopile foundations, jacket foundations, high-pile cap foundations, suction cylinder foundations, monopile composite cylinder foundations, and floating foundations. Among these, monopile foundations and jacket foundations constitute the majority. High-pile cap foundations are used only in some areas of Fujian and Shanghai, with limited use at other sites. Suction cylinder foundations are used throughout the Changle wind farm in Fujian, and in other wind farms, they are mainly in prototype form. Monopile composite cylinder foundations also primarily exist as prototypes. Floating foundations are still in the prototype development stage and are currently difficult to commercialize.

[0003] When installing offshore wind turbines, wind turbine foundation jackets are required to fix them. However, existing wind turbine foundation jackets are prone to shaking when subjected to prolonged seawater impact and cannot provide pressure relief and buffer protection for the entire jacket, thus affecting the overall stability of the wind turbine foundation jacket.

[0004] Therefore, it is of great importance to design a wind turbine foundation jacket to solve the above-mentioned defects. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wind turbine foundation jacket, which aims to solve the technical problems of the existing wind turbine foundation jacket, which are prone to shaking when the jacket is subjected to long-term seawater impact and cannot achieve pressure relief and buffer protection for the entire jacket, thus affecting the overall stability of the wind turbine foundation jacket.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a wind turbine foundation jacket, which includes a jacket body, with steel pipe piles fitted at the four corners of the bottom of the jacket body, mounting seats fixedly connected to the top of multiple sets of steel pipe piles, and protective components installed around the jacket body and between the multiple sets of mounting seats.

[0009] The protective assembly includes a guide rod fixedly installed between two sets of mounting bases. Both ends of the guide rod are fitted with buffer springs. A movable sleeve is slidably connected to the outer side of the guide rod and to the opposite end of the two sets of buffer springs. A transmission arm is rotatably connected to the outer side of the two sets of movable sleeves. A connecting plate is installed between the two sets of transmission arms, and the end of the transmission arm near the connecting plate is rotatably connected to the connecting plate. A force-bearing arc plate is slidably connected to the outer side of the connecting plate. A damper is installed between the connecting plate and the guide rod.

[0010] When using the jacket structure of this technical solution, the fixing sleeve is welded to the outside of the steel pipe pile according to the driving depth of the steel pipe pile. After the steel pipe pile is driven into the seabed, the ballast net cylinder is brought into contact with the seabed. The jacket structure body is hoisted and installed on its top. While grouting the inside of the steel pipe pile, the verticality of the jacket structure body is adjusted to meet the verticality requirements of the foundation. The inside of the ballast net cylinder is filled with block ballast materials such as block concrete and stones to strengthen the bottom of the steel pipe pile. When the jacket structure body is impacted by seawater, the stress arc plate is directly affected by the impact of seawater and buffers it through its own deformation. Then, it pushes the connecting plate to move. Under the transmission of the transmission arm, it pushes the sliding sleeve on the outside of the guide rod to slide. The sliding sleeve pushes the buffer spring and cooperates with the damper for secondary buffering, thereby playing a role in pressure relief and buffer protection.

[0011] Preferably, both ends of the guide rod are welded to the mounting base via mounting feet, and a connecting sleeve is fixedly connected at the connection between the guide rod and the damper. Both ends of the damper are welded to the connecting plate and the connecting sleeve, respectively.

[0012] Furthermore, both ends of the stressed arc plate are fixedly connected to sliders, and both sets of sliders are slidably connected to the outer side of the connecting plate through grooves.

[0013] Furthermore, multiple sets of X-braces are fixedly connected to the inner side of the catheter frame body, and multiple sets of sacrificial anodes are fixedly connected to the outer sides of both the catheter frame body and the multiple sets of X-braces.

[0014] Furthermore, a berthing assembly is fixedly installed on the outside of the jacket body. The berthing assembly includes a ladder fixedly connected to the outside of the jacket body, and an operating platform is fixedly installed at the top of the ladder.

[0015] Furthermore, a transition section is fixedly installed at the top of the guide frame body, an outer platform is fixedly installed at the top of the transition section, and an inner platform is fixedly installed on the inner side of the outer platform.

[0016] Furthermore, a fixing sleeve is fixedly installed on the outer side of the bottom end of the steel pipe pile, and a ballast net cylinder is fixedly installed on the outer side of the fixing sleeve.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model utilizes a coordinated design of steel pipe piles, mounting bases, and protective components. A fixing sleeve is welded to the outside of the steel pipe pile based on its driving depth. After the steel pipe pile is driven into the seabed, the ballast net cylinder contacts the seabed. The hoisting guide frame body is installed at its top. While grouting the inside of the steel pipe pile, the verticality of the guide frame body is adjusted to meet the verticality requirements of the foundation. The inside of the ballast net cylinder is filled with blocky ballast materials such as blocky concrete or stones to reinforce the bottom of the steel pipe pile.

[0020] When the jacket structure is impacted by seawater, the stress-bearing arc plate is directly affected by the impact and first buffers the impact through its own deformation. Then, it pushes the connecting plate to move. Under the transmission of the transmission arm, it pushes the sliding sleeve on the outside of the guide rod to slide. The sliding sleeve pushes the buffer spring and works with the damper to perform secondary buffering, thereby playing a role in pressure relief and buffering protection, and thus improving the overall stability of the jacket structure.

Detailed Implementation

[0028] This specific embodiment is a wind turbine foundation jacket, the structural diagram of which is shown below. Figure 1-6 As shown, the jacket includes a jacket body 1, with steel pipe piles 2 fitted at the four corners of the bottom of the jacket body 1, and mounting seats 3 fixedly connected to the top of multiple sets of steel pipe piles 2. Protective components 4 are installed around the jacket body 1 and between the multiple sets of mounting seats 3.

[0029] First, in this embodiment, the specific structure of the protective component 4 is as follows:

[0030] The protective component 4 includes a guide rod 401 fixedly installed between two sets of mounting seats 3. Both ends of the guide rod 401 are fitted with buffer springs 402. A movable sleeve 403 is slidably connected to the outer side of the guide rod 401 at the opposite end of the two sets of buffer springs 402. A transmission arm 404 is rotatably connected to the outer side of each of the two sets of movable sleeves 403. A connecting plate 405 is installed between the two sets of transmission arms 404, and the end of the transmission arm 404 closest to the connecting plate 405 is rotatably connected to the connecting plate 405. A force-bearing arc plate 4 is slidably connected to the outer side of the connecting plate 405. 06. A damper 407 is installed between the connecting plate 405 and the guide rod 401. When the jacket body 1 is impacted by seawater, the force-bearing arc plate 406 is directly affected by the impact of seawater and first buffers it through its own deformation. Then, it pushes the connecting plate 405 to move. Under the transmission of the transmission arm 404, it pushes the sliding sleeve 403 on the outside of the guide rod 401 to slide. The sliding sleeve 403 pushes the buffer spring 402 and cooperates with the damper 407 to perform secondary buffering, thereby playing the role of pressure relief and buffer protection, and thus improving the overall stability of the jacket body 1.

[0031] Furthermore, both ends of the guide rod 401 are welded to the mounting base 3 via mounting feet 408. A connecting sleeve 409 is fixedly connected at the connection between the guide rod 401 and the damper 407. Both ends of the damper 407 are welded to the connecting plate 405 and the connecting sleeve 409 respectively. The guide rod 401 is welded and fixed to the outside of the mounting base 3 via the mounting feet 408 for easy installation. The damper 407 is assembled between the guide rod 401 and the connecting plate 405 via the connecting sleeve 409.

[0032] Then, both ends of the force-bearing arc plate 406 are fixedly connected with sliders 410, and both sets of sliders 410 are slidably connected to the outer side of the connecting plate 405 through the sliding groove 411. After the force-bearing arc plate 406 receives the impact of seawater, it deforms itself, causing the sliders 410 to slide inside the sliding groove 411, thereby buffering the impact first.

[0033] Furthermore, multiple sets of X-braces 101 are fixedly connected to the inner side of the jacket body 1, and multiple sets of sacrificial anodes 102 are fixedly connected to the outer side of both the jacket body 1 and the multiple sets of X-braces 101. The multiple sets of X-braces 101 ensure the overall strength and stability of the jacket body 1, while the sacrificial anodes 102, through the principle of electrochemical corrosion, preferentially dissolve and release electrons as active metals, making the steel jacket body 1 a cathode, inhibiting corrosion reaction, thereby improving the service life of the jacket body 1.

[0034] Among them, a boat-mounted assembly 103 is fixedly installed on the outside of the jacket body 1. The boat-mounted assembly 103 includes a ladder 104 fixedly connected to the outside of the jacket body 1. An operating platform 105 is fixedly installed at the top of the ladder 104. The boat-mounted assembly 103 facilitates maintenance operations for operators.

[0035] Secondly, a transition section 106 is fixedly installed at the top of the jacket body 1, an outer platform 107 is fixedly installed at the top of the transition section 106, and an inner platform 108 is fixedly installed on the inner side of the outer platform 107. The transition section 106 adopts a plate-beam composite structure to connect the wind turbine tower and the jacket body 1. The dynamic load is dispersed by the main cylinder strengthening ring plate and multiple support beams, which significantly improves the structural deformation resistance and overall stiffness.

[0036] Finally, a fixing sleeve 201 is fixedly installed on the outer side of the bottom end of the steel pipe pile 2, and a ballast net cylinder 202 is fixedly installed on the outer side of the fixing sleeve 201. The fixing sleeve 201 is welded to the outer side according to the driving depth of the steel pipe pile 2, so that the ballast net cylinder 202 is in contact with the seabed. The inside of the ballast net cylinder 202 is filled with block ballast materials such as block concrete, stones, etc., thereby strengthening the bottom end of the steel pipe pile 2 and further improving the overall stability of the jacket body 1.

[0037] When using the device of this technical solution, the fixing sleeve 201 is welded to the outside of the steel pipe pile 2 according to the driving depth of the steel pipe pile 2. After the steel pipe pile 2 is driven into the seabed, the ballast net cylinder 202 is in contact with the seabed. The hoisting guide frame body 1 is installed on its top. While grouting the inside of the steel pipe pile 2, the verticality of the guide frame body 1 is adjusted to meet the verticality requirements of the foundation. The inside of the ballast net cylinder 202 is filled with block ballast materials such as block concrete, stones, etc., to strengthen the bottom end of the steel pipe pile 2. When the guide frame body 1 is impacted by seawater, the force-bearing arc plate 406 is directly affected by the impact of seawater and buffers it through its own deformation. Then, it pushes the connecting plate 405 to move. Under the transmission of the transmission arm 404, it pushes the moving sleeve 403 on the outside of the guide rod 401 to slide. The moving sleeve 403 pushes the buffer spring 402 and cooperates with the damper 407 for secondary buffering, thereby playing the role of pressure relief and buffer protection. The whole operation process is simple and convenient. This utility model improves the overall stability of the guide frame body 1 through design.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
