Description

Technical Field

[0001] This invention relates to the field of wind power foundation technology, specifically to an offshore wind power foundation structure. Background Technology

[0002] Offshore wind power foundation structures are customized marine engineering load-bearing structures that provide stable support for offshore wind turbine generators and realize load transfer and seabed fixation.

[0003] Existing offshore wind power foundation structures can be divided into two types: the first is anchored foundation and the second is floating foundation. Anchored foundations are further divided into monopile foundations, negative pressure cylinder foundations, and other methods.

[0004] Among them, the negative pressure cylinder foundation may experience slight leakage during use, which will lead to a decrease in the negative pressure effect, resulting in instability and posing certain risks to offshore wind power.

[0005] Meanwhile, the negative pressure cylinder foundation requires long-term maintenance during use, and each maintenance requires manual access to the blower for vacuuming, resulting in high maintenance costs. Furthermore, there are certain risks associated with personnel climbing the platform at sea. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an offshore wind power foundation structure that solves the problems of pressure relief, high maintenance costs, and unsafe personnel maintenance.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an offshore wind power foundation structure, including a platform and a connecting column fixedly installed on the lower surface of the platform, the lower end of the connecting column is provided with an anchoring mechanism, the upper end of the anchoring mechanism is provided with a pressure-type depth sensor, the anchoring mechanism is provided with a triggering mechanism inside, and a stabilizing mechanism is fixedly installed at the lower end of the anchoring mechanism; The anchoring mechanism includes an anchor column, the interior of which is filled with carbon dioxide; The triggering mechanism includes a glass tube filled with prehydrated quicklime powder. Annular grooves are formed on the outer sides of both ends of the glass tube, and rectangular grooves are formed on the outer surface of the glass tube. The stabilizing mechanism includes a cone with a through-hole inside, which communicates with the interior of the anchoring column. A high-strength water-soluble sealing membrane is fixedly installed at the lower end of the cone, and a puncture blade is also fixedly installed at the lower end of the cone. The connection hole is covered by the high-strength water-soluble sealing membrane. The puncture blade is perpendicular to the center line of the connection hole and is located inside the high-strength water-soluble sealing membrane, with the tip of the puncture blade pointing towards the high-strength water-soluble sealing membrane.

[0008] Furthermore, a top plate is fixedly installed at the upper end of the anchoring column, and an annular reinforcing rib is fixedly installed on the side of the top plate near the inside of the anchoring column. A groove is formed in the middle of the side of the top plate near the inside of the anchoring column.

[0009] Furthermore, a fixing mechanism is fixedly installed at the lower end of the connecting column, and the pressure-type depth sensor is fixedly installed on the upper surface of the top plate.

[0010] Furthermore, the lower end of the fixing mechanism is fixedly connected to the upper surface of the anchoring mechanism, and the pressure-type depth sensor is located inside the fixing mechanism.

[0011] Furthermore, the fixing mechanism includes a fixing column, the lower half of which has a communicating cavity, and the outer side of which has a communicating hole, which communicates with the interior of the communicating cavity.

[0012] Furthermore, a guide block is fixedly installed on the outer side of the upper end of the anchoring column, and a guide hole is opened through the middle of the guide block.

[0013] Furthermore, the cone is cone-shaped, and several anti-reverse bodies are fixedly installed on the outer surface of the cone.

[0014] Furthermore, one end of the glass tube is fixedly connected to one side surface of the groove, and the end of the glass tube away from the groove is fixedly connected to the inner wall of the anchoring column.

[0015] Furthermore, the rectangular groove is connected to the annular groove, and the depth of both the rectangular groove and the annular groove is 3mm-5mm.

[0016] Furthermore, a tower is fixedly installed on the middle of the upper surface of the platform, and a fan assembly is fixedly installed on the upper end of the tower.

[0017] Compared with the prior art, the present invention provides an offshore wind power foundation structure with the following advantages: 1. By setting up an anchoring mechanism, the present invention can press the stabilizing mechanism into the seabed through negative pressure and seawater pressure, ensuring the stability of the offshore wind power foundation. At the same time, due to the presence of seawater, the anchoring mechanism can remain stable continuously, and there is no need for subsequent depressurization maintenance steps, thus achieving the effects of no depressurization, low maintenance cost, and personnel safety.

[0018] 2. By setting up a stabilizing mechanism, the present invention can enter the seabed under the pressure of seawater. At the same time, by relying on the cone shape, the contact area with the seabed is reduced, the resistance of the seabed is reduced, and the cone can enter the seabed smoothly. Meanwhile, the anti-reverse body, together with the pressure of the seabed and seawater, can prevent the stabilizing mechanism from resetting, thereby achieving the effect of low maintenance cost and personnel safety.

[0019] 3. By setting a triggering mechanism, the present invention can quickly break the seawater when the seawater pressure threshold is reached, ensuring that the prehydrated quicklime powder can fully contact the carbon dioxide, ensuring that the carbon dioxide inside the anchor column can be consumed, thereby forming a negative pressure effect, making the seawater wind power foundation more stable, thus achieving the effects of no pressure relief, low maintenance cost, and personnel safety.

[0020] 4. By setting up a fixing mechanism, the present invention can support the upper wind turbine components, while ensuring the stability of its own structure and ensuring that the seawater pressure is accurately transmitted to the top plate, thereby achieving the effects of no pressure leakage, low maintenance cost, and personnel safety.

[0021] 5. By setting up a pressure-type depth sensor, this invention can transmit the depth data of the stabilization mechanism and the anchoring mechanism at any time, so that ground personnel can always keep track of the status of the stabilization mechanism and the anchoring mechanism, thereby achieving the effect of low maintenance cost and personnel safety.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 11 In this embodiment, an offshore wind power foundation structure includes a platform 3, which provides a safe area for maintenance personnel, and a connecting column 4 fixedly installed on the lower surface of the platform 3. A tower 2 is fixedly installed in the middle of the upper surface of the platform 3, and a wind turbine assembly 1 is fixedly installed at the upper end of the tower 2. A fixing mechanism 5 is fixedly installed at the lower end of the connecting column 4. The fixing mechanism 5 includes a fixing column 51, which provides support for the connecting column 4 and ensures the stability of the connecting column 4. This ensures the stability of the connecting column 4. The connecting hole 53 is connected to the inside of the connecting cavity 52, which ensures that the pressure of seawater can enter the inside of the connecting cavity 52, ensuring that there is always pressure on the top plate 66. The lower end of the fixing mechanism 5 is fixedly connected to the upper surface of the anchoring mechanism 6. The lower end of the connecting column 4 is provided with the anchoring mechanism 6. The lower end of the anchoring mechanism 6 is fixedly installed with the stabilizing mechanism 7. The stabilizing mechanism 7 includes a cone 71. The cone 71 is cone-shaped, so that under the pressure of seawater, the cone 71 can quickly insert the anchoring mechanism 6 into the seabed. Several anti-reverse bodies 72 are fixedly installed on the outer surface of the cone 71. The anti-reverse bodies 72 are inclined in a way that allows them to quickly insert into the seabed and embed themselves in the seabed to prevent them from detaching from the seabed. The inner diameter of the anti-reverse bodies 72 increases at equal intervals from bottom to top. Furthermore, a connecting hole 73 is provided through the interior of the cone 71, which communicates with the interior of the anchoring column 63. The outside of the connecting hole 73 is covered by a high-strength water-soluble sealing membrane 74. Simultaneously, an annular serrated piercing blade 75 is fixedly installed on the outer periphery of the connecting hole 73. The piercing blade 75 is perpendicular to the center line of the connecting hole 73 and is located inside the high-strength water-soluble sealing membrane 74, with its tip pointing towards the membrane. Therefore, when the cone 71 contacts the seabed, the high-strength water-soluble sealing membrane 74 is the first to contact the seabed. The high-strength water-soluble sealing membrane 74 can deform under pressure, and its inner wall adheres to the connecting hole 73. When the connection... When the hole 73 is being fitted, the piercing blade 75 first contacts the high-strength water-soluble sealing membrane 74. Then, under the gravity of the cone 71, the piercing blade 75 can pierce the high-strength water-soluble sealing membrane 74. Before the cone 71 reaches the seabed, the high-strength water-soluble sealing membrane 74 is not compressed, and the tip of the piercing blade 75 does not contact the high-strength water-soluble sealing membrane 74. At the same time, the bottom of the cone 71 is protected by a protective shell before installation in the water, thereby preventing the high-strength water-soluble sealing membrane 74 from breaking prematurely during transportation. The breaking time of the high-strength water-soluble sealing membrane 74 is later than the breaking time of the glass tube 81. The high-strength water-soluble sealing membrane 74 is existing technology and will not be described in detail here. An anchoring mechanism 6 is equipped with a pressure-type depth sensor 9 at its upper end. The pressure-type depth sensor 9 can provide real-time feedback on the depth position of the anchoring mechanism 6. After the wind power foundation structure is installed, the position of the anchoring mechanism 6 will not change. At this time, the upward movement threshold of the anchoring mechanism 6 is set. During later use, if the anchoring mechanism 6 moves upward, the pressure-type depth sensor 9 can transmit the information to the control console on the platform 3 through the communication module. Then, the control console on the platform 3 transmits the information to the ground control terminal through the communication module, thereby issuing a movement warning for the anchoring mechanism 6. The pressure-type depth sensor 9 is existing technology and will not be described in detail here. The pressure-type depth sensor 9 and the communication module have been treated to be waterproof and corrosion-resistant, thereby ensuring stable operation in seawater. The communication module, control console, communication module, and ground control terminal are existing technologies and will not be described in detail here, and are not shown in the figure. The pressure-type depth sensor 9 is fixedly installed on the upper surface of the top plate 66. The deformation of the top plate 66 will not affect the use of the pressure-type depth sensor 9. The pressure-type depth sensor 9 is located inside the fixing mechanism 5. The anchoring mechanism 6 is equipped with a triggering mechanism 8. The anchoring mechanism 6 includes an anchoring column 63, which is filled with carbon dioxide. Carbon dioxide gas is injected into the anchoring column 63 through a one-way valve, which is then sealed by welding to ensure the airtightness of the anchoring column 63. The one-way valve is existing technology and will not be described in detail here, nor is it shown in the figure. Therefore, when the anchoring column 63 enters the sea, before the stabilizing mechanism 7 is in contact with the seabed, the sea pressure generated by the depth reached by the anchoring mechanism 6 deforms the top plate 66. At this time, the glass tube 81 is crushed and breaks, exposing the pre-hydrated quicklime powder inside the glass tube 81. Simultaneously, the high-strength water-soluble sealing membrane 74 maintains the seal on the connection hole 73. Therefore, the carbon dioxide inside the anchoring column 63 reacts with the exposed pre-hydrated quicklime powder, the carbon dioxide is consumed, and the internal pressure of the anchoring column 63 begins to decrease. As the anchoring mechanism 6 continues to move downwards, when the stabilizing mechanism 7 reaches the seabed, the high-strength water-soluble sealing membrane 74 is blocked by the seabed and expands outwards through the seawater. The high-strength water-soluble sealing membrane 74 completes the initial flattening of the connection hole 73 and the seabed. At the same time, the high-strength water-soluble sealing membrane 74 is pushed and squeezed by the stabilizing mechanism 7. At this time, the piercing blade 75 comes into contact with the high-strength water-soluble sealing membrane 74, and then the high-strength water-soluble sealing membrane 74 is pierced by the piercing blade 75. Meanwhile, the prehydrated quicklime powder and carbon dioxide inside the anchoring column 63 continue to react and reduce the negative pressure. At this time, the anchoring column 63 can drive the anchoring mechanism 6 and the stabilizing mechanism 7 into the seabed through its own negative pressure and the pressure of the seawater. Compared with the existing installation methods that rely on hammering, the present invention can reduce the disturbance to seabed sediments and reduce the damage to benthic organism habitats. A guide block 61 is fixedly installed on the outer side of the upper end of the anchoring column 63. A guide hole 62 is opened through the middle of the guide block 61. When the anchoring mechanism 6 is placed in the sea, the guide block 61 and the guide hole 62 cooperate with the pre-set retractable telescopic guide rod and the guide hole 62 to provide a stable guiding effect for the anchoring mechanism 6 under the condition of seawater swaying, ensuring that the stabilizing mechanism 7 accurately contacts the seabed and ensuring the stability of subsequent installation. The telescopic guide rod is existing technology and will not be described in detail here. A top plate 66 is fixedly installed on the upper end of the anchoring column 63. A ring-shaped reinforcing rib 65 is fixedly installed on the side of the top plate 66 near the inside of the anchoring column 63. The ring-shaped reinforcing rib 65 can ensure the stability of the edge side of the top plate 66 and avoid deformation caused by pressure. A groove 64 is opened in the middle of the side of the top plate 66 near the inside of the anchoring column 63. The groove 64 can reduce the stability of the top plate 66 at this location, so that it can be directionally recessed when the specified seawater pressure is reached, ensuring the accurate operation of the triggering mechanism 8. The triggering mechanism 8 includes a glass tube 81 filled with prehydrated quicklime powder. Meanwhile, the carbon dioxide inside the anchoring column 63 is protected and sealed by a high-strength water-soluble sealing membrane 74. The prehydrated quicklime powder accelerates the reaction with the carbon dioxide, rapidly consuming it and creating a negative pressure inside the anchoring column 63. This pressure from the seawater pushes the anchoring mechanism 6 and the stabilizing mechanism 7. When the stabilizing mechanism 7 contacts the seabed, the piercing blade 75 punctures the high-strength water-soluble sealing membrane 74 and enters the seabed. After the high-strength water-soluble sealing membrane 74 is punctured, the sealing environment of the anchoring column 63 is broken, and a new sealed chamber is formed between the anchoring column 63 and the seabed. When the carbon dioxide is consumed by the prehydrated quicklime powder, a pressure difference is created between the anchoring column 63 and the seawater. This pressure difference pushes the anchoring mechanism 6 downwards, causing the stabilizing mechanism 7 to enter the seabed. The glass cylinder 81 is made of borosilicate glass, which is more impact-resistant than soda-lime glass, ensuring it won't break prematurely during transport. Compared to tempered glass, which breaks into small particles that cause lime to clump together, reducing the reaction area with carbon dioxide and increasing the reaction time, borosilicate glass ensures the glass cylinder 81 breaks smoothly, reducing the risk of premature breakage and guaranteeing the reaction time and area for carbon dioxide. One end of the glass cylinder 81 is fixedly connected to one side of the groove 64, and the end away from the groove 64 is fixedly connected to the inner wall of the anchor column 63. When the groove 64 undergoes directional deformation, the glass cylinder 81 is compressed and can break. The glass cylinder 81 has annular grooves 83 on both outer sides of its two ends, and rectangular grooves 82 on its outer surface. The rectangular grooves 82 are connected to the annular grooves 83. The rectangular grooves 82 and the annular grooves 83 can fully break the glass cylinder 81, increasing the contact area between the prehydrated quicklime powder and carbon dioxide, thereby accelerating the reaction. The depth of the rectangular grooves 82 and the annular grooves 83 is 3mm-5mm. If the depth of the rectangular grooves 82 and the annular grooves 83 is too deep, the glass cylinder 81 is prone to breakage during transportation. If the depth of the rectangular grooves 82 and the annular grooves 83 is too shallow, the glass cylinder 81 will not break sufficiently, causing some glass fragments to cover the prehydrated quicklime powder, resulting in a reduction in the reaction area and a decrease in the reaction rate. This invention utilizes carbon dioxide protected by a high-strength water-soluble sealing membrane 74 inside the anchoring column 63. This carbon dioxide reacts with the pre-hydrated quicklime powder inside the triggering mechanism 8, thereby consuming the carbon dioxide and creating a negative pressure inside the anchoring column 63. Simultaneously, when the piercing blade 75 punctures the high-strength water-soluble sealing membrane 74 and enters the seabed, the anchoring column 63 can re-establish a negative pressure with the seabed. This creates a significant pressure difference between the seawater pressure and the internal pressure of the anchoring column 63. This pressure difference can push the anchoring mechanism 6 to press the stabilizing mechanism 7 into the seabed, thus achieving the effects of no vacuuming device, continuous stability without pressure relief, and no need for subsequent pressure evacuation maintenance. Compared with existing technologies, this invention addresses the shortcomings of existing negative pressure cylinder foundations, which are prone to leakage and require equipment for vacuuming maintenance. The present invention uses a combination of a cone-shaped cone 71 and several anti-reverse bodies 72. The cone 71 can reduce the resistance when inserted into the seabed, while the anti-reverse bodies 72 can prevent the stabilizing mechanism 7 from resetting. Compared with the prior art, the present invention has the following characteristics: the existing anchored foundation lacks an anti-reset structure and its stability depends on continuous negative pressure. This invention uses borosilicate glass in the glass cylinder 81 and contains prehydrated quicklime powder. When the set seawater pressure threshold is reached, the quicklime powder can be directionally broken, allowing it to quickly consume carbon dioxide and thus create negative pressure inside the anchor column 63. Compared with the prior art, the negative pressure of the prior art requires manual vacuuming with equipment, and continuous vacuuming maintenance is required in the later stage, resulting in high maintenance costs. This invention uses a pressure-type depth sensor 9 installed on the upper end of the anchoring mechanism 6 to provide real-time feedback on the depth data of the stabilizing mechanism 7 and the anchoring mechanism 6. This allows ground personnel to remotely monitor the status of the stabilizing mechanism 7 and the anchoring mechanism 6 without the need for regular manual inspections at sea. Compared with existing technologies, which lack real-time monitoring methods and require personnel to climb onto the platform for maintenance, resulting in high maintenance costs and certain safety risks. The present invention provides a guide block 61 on the outer side of the upper end of the anchor column 63, with a guide hole 62 penetrating the middle of the guide block 61. This allows for stable movement during installation in conjunction with a retractable telescopic guide rod, ensuring accurate installation even in turbulent seawater environments. Compared with existing technologies, the present invention addresses the problem that existing wind power foundation structures are susceptible to interference from seawater during installation, leading to deviations in the anchoring position and consequently affecting the stability of the foundation. The fixed column 51 of the present invention has a connecting cavity 52 in its lower half and a connecting hole 53 through it on the outer side, which can achieve stable support for the wind turbine assembly 1 and also ensure that the pressure of seawater is accurately transmitted to the top plate 66, ensuring the directional deformation of the top plate 66. Compared with the prior art, the fixed structure of the prior art does not have the effect of providing space and support stability for pressure transmission.

[0026] The working principle of the above embodiment is as follows: When installing offshore wind power foundations, seabed exploration is first required to ensure that the seabed environment is suitable for the smooth installation of the offshore wind power foundations and to determine the depth. Then, the required offshore wind power foundation components are transported to the designated location by self-floating tow. First, the telescopic guide rods corresponding to the guide block 61 and guide hole 62 are brought into contact with the seabed and kept stable. Then, the connecting column 4, anchoring mechanism 6, and stabilizing mechanism 7 are lifted by a lifting device. The guide hole 62 is aligned with the telescopic guide rod, and the telescopic guide rod is adapted to the guide hole 62. Therefore, through the guidance of the guide block 61, guide hole 62, and telescopic guide rod, the connecting column 4, fixing mechanism 5, anchoring mechanism 6, and stabilizing mechanism can be aligned. 7. Stability during sea lowering: When the anchoring mechanism 6 enters the sea, the seawater pressure continuously increases. As the seawater pressure increases, the pressure on the top plate 66 also increases. When the anchoring mechanism 6 is about to reach the seabed, the pressure on the top plate 66 reaches its deformation value, causing deformation. Simultaneously, due to the groove 64 and the annular reinforcing rib 65, deformation occurs at the position corresponding to the groove 64, while the position corresponding to the annular reinforcing rib 65 remains unchanged, thus achieving directional deformation. Furthermore, the groove 64 does not undergo further deformation after deformation. This deformation of the groove 64 applies pressure to the glass cylinder 81, while the inner wall of the anchoring column 63 exerts relative pressure on the other end of the glass cylinder 81. When the pressure exceeds the structural support force of the glass cylinder 81, the glass cylinder 81 breaks. Due to the opening of the rectangular groove 82 and the annular groove 83, the two ends and the periphery of the glass cylinder 81 break. The breakage of the glass cylinder 81 causes the prehydrated quicklime powder to react with the carbon dioxide inside the anchoring column 63. At the same time, the high-strength water-soluble sealing membrane 74 ensures that the carbon dioxide does not leak. At this time, the anchoring mechanism 6 drives the stabilizing mechanism 7 to continue to move downward. The high-strength water-soluble sealing membrane 74 first contacts the seabed and begins to unfold under pressure. The cone 71 continues to move downward, and the piercing blade 75 on the connecting hole 73 contacts the high-strength water-soluble sealing membrane 74 and pierces it. At the same time, the piercing blade 75 enters the seabed. At this time, the inside of the anchoring column 63 is in contact with the sea. A sealed environment is re-established at the bottom. At this point, the carbon dioxide inside the glass tube 81 is consumed by the pre-hydrated quicklime powder, reducing the carbon dioxide content. This creates a negative pressure inside the anchor column 63. The pressure of the seawater relative to this negative pressure increases, causing the anchor column 63 to move towards the seabed. Simultaneously, the stabilizing mechanism 7 moves towards the seabed, and the depth data uploaded by the pressure-type depth sensor 9 continues to increase slowly. Once the stabilizing mechanism 7 reaches the seabed, one side of the anti-reverse valve 72 engages with the seabed, preventing the stabilizing mechanism 7 from moving to its initial position and ensuring the stability of the offshore wind power foundation. The stability of the anchor column 63 and the stabilizing mechanism 7 relies on the long-term support of the seawater pressure.The pressure-type depth sensor 9 can detect the movement of the stabilizing mechanism 7 and the anchoring mechanism 6. When movement occurs, the pressure-type depth sensor 9 can transmit data to the ground.

[0027] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
