Description

Technical Field

[0001] The present invention relates to the technical field of floating wind power, and in particular to a semi-submersible wind power foundation with an FRP reinforced UHPC structure. Background Art

[0002] A semi-submersible wind turbine foundation is a floating wind turbine structure designed for use in deep or offshore waters. Part of the structure is located above the water surface, while the other part is submerged below the water surface. The central part supports the wind turbine and blades for wind power generation.

[0003] However, the existing semi-submersible wind power foundation still has the following defects:

[0004] First, semi-submersible wind turbine foundations are built offshore and are often exposed to strong winds and waves. Wind turbine facilities are often attacked by strong sea breezes. Floating on the sea, with their bottoms connected to the seabed, rough waves inevitably affect the seabed at the bottom, causing the seabed soil to shake and loosen. Although the bottom of the wind turbine foundation is not directly in contact with the seabed, it is connected to a long anchor cable, which is fixed to the seabed, making the wind turbine foundation semi-float on the sea surface to prevent it from completely drifting away due to lack of connection to the seabed. The loose and detached seabed soil reduces the stability of the anchor cable, and thus the stability of the entire wind turbine foundation on the sea surface, causing the wind turbine to shake and vibrate irregularly in wind and waves. This instability may damage the structural integrity of the wind turbine and shorten its service life. At the same time, loose soil may cause instability in the anchoring system of the semi-submersible wind turbine foundation, such as the anchor chain and anchor, causing the wind turbine foundation to shift or even completely lose its fixed position, posing a great risk to the operation and maintenance of the wind farm.

[0005] Secondly, when a wind turbine foundation stands on the sea surface for a long time, it will be hit by waves. The seawater will carry various substances, including organic matter and microorganisms, which will eventually be hit on the wind turbine foundation. These substances will form a sediment layer on the surface. Although UHPC has high corrosion resistance, substances such as hydrogen sulfide produced by sulfate-reducing bacteria, organic acids produced by certain bacteria, as well as chlorides and biological deposits will still have an adverse effect on UHPC over a long period of time. They will destroy the protective layer on the surface of the wind turbine foundation and cause corrosion damage to the metal material. At the same time, the damage will form microcracks and holes, reducing the cross-sectional area of ​​the material and its ability to bear loads. This will increase the risk of wind turbine facilities under the action of wind and waves and reduce overall stability.

[0006] Finally, semi-submersible wind turbine foundations are located in ocean areas for a long time. Engineers need to understand the flow of the ocean, the degree of wind and wave fluctuations in the area when working on the wind turbine foundations. This is of great significance to marine scientific research. However, the existing wind turbine foundations only provide support and cannot know the conditions of the sea area. The lack of monitoring of ocean flow and wave height may lead to the inability to timely discover potential safety risks. Monitoring of marine environmental parameters is crucial for assessing the impact of wind farms on the surrounding environment. If the ocean flow and wave conditions cannot be accurately monitored, it will be difficult to assess and predict the impact of wind farms on the marine ecosystem. Summary of the Invention

[0022] (3) Beneficial effects

[0023] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0024] 1. By providing a push plate 1, a spacer 1 and an internal long cylinder, the horizontal plate 1 is pushed by the action of sea water and slides horizontally at the same time, the horizontal plate 1 is connected to the push plate 1 to slide, and the push plate 1 drives the spacer 1 connected at both ends to rotate inside the bottom shell to deflect, and the spacer 1 is connected to the upper spacer 2 to deflect, and the spacer 1 and the spacer 2 are alternated during the deflection, and the material box placed above the spacer 2 is transported downward, and the through ring falls under the path restriction of the internal long cylinder and the rope, and finally falls to the seabed pile, is opened and the internal material is released.

[0025] 2. By providing a second horizontal plate, a bending plate and an arc scraper, the push plate 2 is attacked by the waves and is pushed, and the push plate 2 drives the upright slider to slide in the slide groove. Due to the shape design of the slide groove, the upright slider can allow the bending plate to slide up and down, and the other end of the bending plate can drive the horizontal slider to slide in the horizontal direction.

The long connecting column and the short connecting column can be rotatably connected to the column to ensure that they do not drift away.

[0042] The present invention will be further described below with reference to the embodiments.

[0043] A semi-submersible wind power foundation of an FRP-reinforced UHPC structure in this embodiment is as follows: Figure 1 - Figure 9 As shown, it includes a support mechanism 100, which includes a column 101.

[0056] Compared with existing technologies, this device can monitor the ocean flow conditions, especially the degree of wind and waves, in the sea area around the wind power foundation in real time, allowing operators to promptly detect potential safety risks. In addition, it can monitor and evaluate the environmental conditions around the wind farm and further evaluate the marine ecology of the area.

[0057] The following is the specific working principle of the above embodiment:

[0058] A semi-submersible wind turbine foundation is a type of floating offshore wind turbine foundation. The wind turbine is installed on a floating platform, and then the Rudong platform is submerged in the ocean. Its bottom end is connected to the seabed through a rope chain to fix the wind turbine, providing electricity for wind power generation at sea.

[0059] However, there are often strong winds and waves on the sea surface, and the seawater will surge greatly, which will cause the seabed part at the bottom to be affected by the seawater. The impact of the seawater will make the seabed soil loose, which will reduce the stability of the wind power foundation anchoring, so the loose soil needs to be solidified. First, the first step is to take place. When the wind and waves are strong, the seawater will push the push plate 1 202 located in the bottom shell 105. The push plate 1 202 is subjected to the thrust of the seawater and its position is offset. Due to the limitation of the bottom shell 105, the push plate 1 202 can only slide horizontally on the bottom shell 105. The push plate 1 202 extends through the side wall of the bottom shell 105 to the inside and is fixedly connected to the cross plate 1 201. The cross plate 1 201 also slides horizontally. The cross plate 1 201 is inside the bottom shell 105 and is slidably connected to it, so that the cross plate 1 201 can perform horizontal reciprocating motion when it is indirectly pushed by the seawater, thereby controlling the descent of the material. The two ends of the horizontal plate 201 are rotatably connected with the spacer 1 203. The left and right sliding of the horizontal plate 201 drives the spacer 1 203 at both ends to rotate at a certain angle, and the upper surface of the spacer 1 203 is fixedly connected to the spacer 2 204. The spacer 1 203 and the spacer 2 204 are arranged crosswise. At the same time, there are four groups of horizontal plates 201 and they surround the column 101. The sliding of one group of horizontal plates 201 can make all four groups of horizontal plates 201 move through the connection of the spacer 1 203. The spacer 203 and the spacer 204 are deflected at a certain angle, and the two are located one above and one below. Initially, since the spacer 204 is located above the spacer 1 203, the material box 205 is placed on the top of the spacer 204, and the spacer 1 203 below does not touch the material box 205. The material box 205 contains a curing agent for solidifying and agglomerating the soil. When the spacer 204 is deflected, the spacer 204 rotates a certain angle by itself, so it changes from directly receiving the material box 205 at the bottom at the beginning to leaving the material box 205 directly below, and rotates to the bottom of the horizontal plate 1 201, that is, rotates to be parallel to the horizontal plate 1 201, and at this time it is parallel to the spacer 203. The partition 1 203 fixedly connected to the partition 204 rotates to the bottom of the material box 205. Since the partition 204 rotates away from the material box 205 and no longer contacts it, the material box 205 will fall downward. The material box 205 drops and falls from the partition 204 onto the partition 1 203, and the horizontal plate 1 201 slides again to allow the partition 1 203 and the partition 2 204 to rotate in opposite directions. After rotation, the partition 1 203 leaves the bottom of the material box 205. At this time, there is no other object to support the bottom of the material box 205, so the material box 205 will fall from above the partition 1 203, and the partition 2 204 will take over the next material box 205.A through ring 206 is fixedly connected to the side of the material box 205, and an internal long tube 207 is provided in the through ring 206. The bottom end of the internal long tube 207 is connected to the rope 103, and the top end is connected to the column 101. The internal long tube 207 and the rope 103 together form a descending track for the material box 205. When the material box 205 falls, it will fall along the path of the internal long tube 207 and the rope 103, and the bottom end of the rope 103 is fixedly connected to the seabed pile 104, which is the anchoring object on the seabed. When the material box 205 falls on the rope 103, it means that the material box 205 has been attached to the seabed. The rope 103 opens the bottom surface of the material box 205 through impact. After that, the solidifying material in the material box 205 will contact and penetrate into the soil on the seabed, making the loose soil harder and less likely to disperse.

[0060] The cam 303 is a vertical cam 304 that is fixed to the top of the support 301 and is connected to the bottom of the support 301. The cam 303 is a vertical cam 304 that is fixed to the top of the support 301. The cam 303 is a vertical cam 304 that is connected to the top of the support 301. The cam 303 is a vertical cam 304 that is connected to the top of the support 301 and is connected to the bottom of the support 301. The bottom shell 105 is fixedly connected to the column 101, which makes the column 101, the support 301 and the vertical frame in the middle of the bending piece 305 become a whole. Therefore, the connection with the vertical frame can ensure that if the bending piece 305 changes its posture, it only rotates at a certain angle with the top of the vertical frame as the center, and no deviation in other directions, including the horizontal direction, will occur during the rotation. Once the movement posture direction of the bending piece 305 is limited, the upright slider 304 connected to the bending piece 305 and the horizontal slider 306 at the other end are also limited. The upright slider 304 only moves towards or away from the column 101, and the horizontal slider 306 moves up and down. Apart from this, the two will not have deviation movements in other directions. The vertical slider 304 will slide perpendicularly to the direction of movement of the horizontal plate 2 302, and the bent piece 305 slidably connected to the vertical slider 304 will also be affected. The movement of the vertical slider 304 forces the bent piece 305 to deflect, and the end thereof away from the column 101 is connected to the vertical slider 304 and rotates, while the end thereof close to the column 101 is connected to the horizontal slider 306 and also rotates. This rotation causes the horizontal slider 306 connected to the bent piece 305 to change in height, which is determined by the posture of the notches on the vertical slider 304 and the horizontal slider 306. When the horizontal slider 306 is rotated, the horizontal slider 306 is rotated. When the slider 306 rises and falls in height due to the rotation of the bending piece 305, the horizontal slider 306 is fixedly connected to the arc scraper 307, and the arc scraper 307 is close to the outside of the column 101 and has the same shape as the column 101. The lifting and lowering of the arc scraper 307 scrapes the outer surface of the column 101 up and down, cleaning the corrosive substances and various microorganisms that are beaten on the column 101 by sea water, and preventing them from staying on the column 101 for a long time and causing damage to the wind power foundation. The substances scraped off by the arc scraper 307 will eventually fall into the collection bin 308, and the operator will finally handle the collection bin 308 in a unified manner.

[0061] The top of the column 101 is also rotatably connected to the support shaft 403, and the long connecting column 402 is fixedly connected to the oblique lower part of the support shaft 403, and the side of the long connecting column 402 away from the support shaft 403 is fixedly connected to the float 401. The mass density of the float 401 is relatively light, and it will float on the sea surface and will float up and down with the ups and downs of the sea water. However, under normal circumstances, the sea water will not have large ups and downs, and the float 401 will only fluctuate up and down to a small extent. However, when the seawater is affected by strong winds, waves will be generated, and the waves will make the buoy 401 fluctuate more violently, and the long connecting column 402 will rotate at a large angle, and the short connecting column 404 will be fixedly connected to the oblique upper part of the support shaft 403. The short connecting column 404 will also rotate at a large angle, and the top of the short connecting column 404 will be fixedly connected to the connecting vessel 405. The connecting vessel 405 will rotate under the influence of the short connecting column 404 and eventually hit the detector 406 fixedly connected to the outer side of the column 101. The height of the detector 406 is adapted to the connecting vessel 405, and the rotation of the connecting vessel 405 can hit the detector 406. When the detector 406 is hit, a series of data such as the number of times the detector 406 is hit, the force direction, etc. can be detected and collected to know the ocean conditions of the sea area, including the wave height and tidal pattern. The approximate wind speed of the sea area and other key information can also be inferred based on the data obtained. By knowing this important information and conducting marine scientific research and monitoring, we can better guide the rational development and protection of marine resources. At the same time, we can also analyze whether the sea area is suitable for setting up a wind power platform foundation more reasonably, so as to provide more reliable help for people's daily life.
