Description

Technical Field

[0001] The present invention relates to the field of offshore engineering production, and more specifically to a floating building for island reefs. Background Art

[0002] With the increasing attention and development of marine resources by various countries, in order to effectively explore, develop and utilize these resources by building stable facilities on island reefs, it is necessary to construct supporting living, production and storage facilities on island reefs. Therefore, a floating building for island reefs is required. The floating building is not restricted by the terrain and geological conditions of the island reef. After the main body is built on land, it can be towed to the designated sea area of the island reef for positioning and anchoring, and can be quickly deployed to meet the temporary or emergency use requirements of the island reef.

[0003] The invention patent with the Chinese patent application number 201510156702.3 is a floating building structure for island reefs, which consists of a building structure part, a hull foundation part and an anchor chain. The technical solution is to complete the overall construction on the land shore first, and then transport it to the designated location of the island reef by the way of overall self-floating towing. After arriving at the destination, water is released into the hull structure to make it sink and contact the island reef, so as to achieve fixation. However, this technical solution has some defects: the seabed topography of the island reef is extremely complex, and the periphery of the seabed of the island reef is generally inclined. When the hull structure sinks and contacts the island reef, it is difficult to ensure uniform contact, which has a negative impact on the overall stability and balance. In the case of long-term exposure to the impact of waves and water currents, the hull structure is extremely prone to displacement or tilt. Moreover, once the hull is displaced or tilted, the anchor chain exerts abnormal forces on the building structure due to the concentrated connection points, resulting in stress concentration at the connection part, causing fatigue damage to the building materials and generating cracks. After the cracks expand, it will cause partial or overall damage to the building.

[0004] Therefore, it is necessary to propose a floating building for island reefs to solve the above technical problems. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a floating building for island reefs, which solves the technical problems that due to the inclined seabed topography of the island reef, it is difficult for the hull to sink and contact evenly, affecting stability and balance, and it is easy to displace and tilt under the impact of waves and water currents, and it will also cause stress concentration at the anchor chain connection part, resulting in building damage.

[0032] The present invention has achieved the following beneficial effects:

[0033] (1) By setting the push claw anchoring assembly, the fixing member, the auxiliary plate, the push claw plate and the push claw member cooperate with each other. The gravity of the hull drives the push claw member to laterally extrude the seabed soil, causing it to accumulate within the push claw plate. The V-shaped and pointed push claw member increases the contact area and grip force with the seabed soil, improving the anchoring effect of the floating building on the seabed. At the same time, the driving assembly utilizes the gravity transmission of the hull structure to drive the three groups of push claw members to perform radial movement on the seabed to achieve radial fixation, further enhancing the stability. In addition, the anchor hook at the bottom of the passive block can effectively prevent the hull from sliding on the inclined seabed. The fixed disk below the driving rod adapts to the uneven seabed through the telescopic sleeve rod, and the anti-slip rubber pad at the bottom of the hull enhances the friction with the seabed. The combined action of these structures comprehensively improves the stability of the floating building on the seabed, effectively solving the problem in the prior art that the hull structure is prone to displacement or inclination under the long-term impact of waves and water currents.

[0034] (2) By setting the shock absorber seat at the top of the adjusting plate, the shock absorption system composed of the shock absorption spring rod and the shock absorption plate inside it can effectively buffer the vibration and impact force transmitted from the compartment seat to the adjusting plate. The setting of the universal joint makes the connection between the anchor chain and the shock absorber seat more flexible, avoiding excessive wear or breakage of the anchor chain caused by improper angles, making the force exerted by the anchor chain on the compartment seat more uniform, and greatly reducing the possibility of stress concentration at the connection part, thereby reducing the risk of fatigue damage and cracks in the building materials due to stress concentration.

[0035] (3) By setting a V-shaped structure formed by the adjusting plate and the hypotenuse at the left end of the hull structure, and the flow deflector at the bottom of the adjusting plate, it can effectively guide the oncoming tide to both sides or change the tide direction to impact the hull, increasing the friction between the hull and the seabed and enhancing the hull stability.

Detailed implementation manners

[0046] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0047] As Figure 1 - Figure 2 shown, a floating building for island reefs includes a hull structure 1 and a floating building body 13. The hull structure 1 has a horizontal end, providing a bearing foundation and floating ability for the entire floating building body 13. An inlet structure is provided inside the hull structure 1 to facilitate sinking to the seabed later. The right end of the hull structure 1 sinks into the seabed along one side in the direction of the island reef; Adjusting plate 11: The adjusting plate 11 is arranged on the top of the hull structure 1 and has an overall L-shaped structure. One end is rotatably connected to the hull structure 1, and its angle can be adjusted by rotation to adapt to different usage requirements and environmental conditions; Compartment seat 12: The compartment seat 12 is arranged below the floating building body 13 and is located on the adjusting plate 11, providing floating ability for the floating building body 13. An anchor chain is arranged between the adjusting plate 11 and the compartment seat 12. As Figure 1 shown, the hull structure 1 in the overall device has not sunk into the seabed;

[0048] As Figure 2 - Figure 5As shown, the push claw anchoring assembly 2: The push claw anchoring assembly 2 is arranged below the hull structure 1. When the floating building reaches the designated position on the reef, it drives the push claw anchoring assembly 2 to extend into the seabed by means of the gravity of the hull structure 1, increasing the friction with the seabed and realizing the stable anchoring of the floating building at the reef. The push claw anchoring assembly 2 includes: The fixing member 21: The fixing member 21 is arranged at the front and rear ends of the hull structure 1, and the number is three, which is used to provide a stable connection foundation for the entire push claw anchoring assembly 2 to ensure the reliable connection between the push claw anchoring assembly 2 and the hull structure 1; The auxiliary plate 22: An annular auxiliary plate 22 is arranged below the fixing member 21. The auxiliary plate 22 has a tip structure, which helps the auxiliary plate 22 to cut into the seabed more easily during the sinking process following the hull, reducing the resistance. At the same time, the annular structure can disperse the force received by the push claw anchoring assembly 2 to a certain extent; The push claw plate 23 and the push claw member 24: A push claw plate 23 is installed at one end of the auxiliary plate 22 away from the fixing member 21, and a push claw member 24 is installed below the push claw plate 23. When the hull structure 1 sinks into the seabed, its gravity drives the push claw member 24 to laterally squeeze on the seabed, causing the soil inside the seabed to accumulate inside the push claw plate 23, thus playing a stabilizing role. Among them, the push claw member 24 has a V-shaped structure, and its bottom is set as a tip structure. This V-shaped and tip design can increase the contact area and grip of the push claw member 24 with the seabed soil, further improving the stabilizing effect; The hydraulic push rod 25, the fixed end of the hydraulic push rod 25 is rotatably connected to the front and rear ends of the hull structure 1, and the moving end of the hydraulic push rod 25 is rotatably connected to the adjusting plate 11; An angle sensor for rotating the adjusting plate 11 by different angles is installed on the hull structure 1, such as Figure 3 As shown, the hull structure 1 inside the overall device sinks into the seabed.

[0049] It should be noted that when the floating building for the reef sails to the designated position and is ready to sink, the right end of the hull structure 1 sinks along the side in the direction of the reef. The auxiliary plate 22 below the fixing member 21 sinks together with the hull structure 1. The push claw plate 23 connected to one end of the auxiliary plate 22 away from the fixing member 21 and the push claw member 24 below it penetrate into the seabed under the action of the gravity of the hull structure 1. The push claw member 24 is V-shaped and its bottom is a tip. When sinking, it produces a lateral extrusion on the seabed soil, causing the soil to accumulate inside the push claw plate 23. The V-shaped and tip design increases the contact area and grip of the push claw member 24 with the seabed soil, greatly increasing the contact area and grip with the seabed soil, improving the anchoring effect of the floating building on the seabed and enabling it to better resist external forces such as sea waves and water currents;

[0050] When the seabed contacts with the inclined reef, the hull structure 1 is inclined. At this time, the angle sensor detects the adjusting plate 11 and feeds back the detected angle information, thereby driving the hydraulic push rod 25 to push the adjusting plate 11 until the adjusting plate 11 is horizontal on the seabed. The anchor chain on the adjusting plate 11 will have a uniform tension on the compartment seat 12, so as to ensure the stability of the floating building on the inclined seabed and reduce the safety risks caused by the inclination.

[0051] As Figure 5 - Figure 6 shown, the driving assembly 210; it is arranged at the front and rear ends of the hull structure 1 and is used to contact the seabed. Through the reaction force, it drives the three claw members 24 to radially move away from each other, so that the claw members 24 can move laterally on the seabed. The driving assembly 210 includes: a driving rod 211: one end of the driving rod 211 slides through the middle of the fixing member 21 and can move axially in the fixing member 21; a driving rotating plate 212: both ends of the driving rotating plate 212 are rotatably connected to the upper middle part of the auxiliary plate 22 and the lower part of the driving rod 211 through rotating shafts respectively, and the movement of the driving rod 211 drives the auxiliary plate 22 to rotate around the rotating shaft connected to the fixing member 21; a spring compression plate 213: the spring compression plate 213 is fixed above the driving rod 211, and the spring inside the spring compression plate 213 is sleeved outside the driving rod 211, which is used to store and release energy and provide power for the movement of the driving rod 211; a concave frame 214: the concave frame 214 is installed on the top of the fixing member 21, and the top end of the spring compression plate 213 slides through the concave frame 214 to guide the movement of the spring compression plate 213; an L-shaped frame 215: one side of the L-shaped frame 215 is installed on the hull structure 1. A square groove is opened at the vertical end of the L-shaped frame 215. The first rollers 216 are installed at the front and rear ends in the square groove. The second roller 217 is installed on the fixing member 21. A sleeve 218 is installed at the end of the horizontal end of the L-shaped frame 215. A passive block 219 is slidably connected below the sleeve 218. An expansion spring plate 2191 is installed inside the sleeve 218. A steel cable is installed on the second roller 217. One end of the steel cable passes through the two first rollers 216 and extends into the sleeve 218 and is fixed to the passive block 219.

[0052] It should be noted that in the initial stage when the floating building sails to the designated position of the reef and is about to sink, the passive block 219 extends below the hull structure 1. At this time, the spring inside the spring compression plate 213 is in a compressed energy storage state, and the entire drive assembly 210 is in a waiting-to-be-triggered state. When the hull structure 1 sinks and contacts the seabed, the passive block 219 first contacts the seabed surface. Due to the gravitational force of the continuous sinking of the hull structure 1, the seabed generates an upward reaction force on the passive block 219. This reaction force causes the passive block 219 to move into the sleeve 218, thereby compressing the expansion spring plate 2191 inside the sleeve 218. The movement of the passive block 219 is transmitted through the steel cable fixedly connected to it. The steel cable bypasses the second roller 217 and the two first rollers 216 in the square groove in sequence, changing the direction of the force. After the expansion spring plate 2191 is compressed to a certain extent, the spring inside the spring compression plate 213 that was originally in a compressed state to store energy begins to release energy. The elastic force of the spring pushes the drive rod 211 to move downward along its sliding channel in the fixing member 21. The downward movement of the drive rod 211 drives the movement of the drive rotating plate 212. The movement of the drive rotating plate 212 causes the auxiliary plate 22 to rotate radially around the rotating shaft connected to the top of the fixing member 21. The radial movement of the auxiliary plate 22 finally drives the three groups of pawl members 24 to perform radial movement on the seabed, achieving radial fixation. The drive assembly 210 can utilize the gravitational transmission of the hull structure 1 to drive the three groups of pawl members 24 to be radially fixed on the seabed, thereby greatly enhancing the stability of the floating building on the seabed and enabling it to better resist external forces such as waves and water currents;

[0053] As Figure 5 - Figure 6 shown, an anchor hook 2192 is installed at the bottom of the side of the passive block 219 facing away from the reef, and the end of the anchor hook 2192 away from the passive block 219 is in a pointed structure.

[0054] It should be noted that when the hull structure 1 sinks to the seabed on the inclined reef, due to the inclination of the seabed, the hull structure 1 has a tendency to slide downward along the slope. The anchor hook 2192 can more easily wedge into the surface of the inclined seabed with its pointed structure. Whether it is soft sediment or hard rock, the tip can effectively cut in. When the hull has a tendency to slide downward, the anchor hook 2192 will receive a pulling force from the direction of the hull's downward slide. Through its interaction with the seabed medium, it generates a strong reverse resistance, directly opposing the downward sliding force of the hull structure 1, thereby effectively preventing the hull structure 1 from sliding on the seabed.

[0055] As Figure 5As shown, a fixed disk 2193 is installed below the driving rod 211, and a ring-arrayed telescopic sleeve rod 2194 is installed below the fixing member 21. The moving end of the telescopic sleeve rod 2194 is fixed on the fixed disk 2193. The side of the fixed disk 2193 facing away from the telescopic sleeve rod 2194 is set as a rough structure, and a groove 2195 for storing the auxiliary plate 22 is formed around the fixed disk 2193.

[0056] It should be noted that when the driving rod 211 drives the fixed disk 2193 to move downward and contact the seabed, the unevenness of the seabed surface will cause the fixed disk 2193 to receive uneven forces. At this time, the telescopic sleeve rod 2194 can automatically expand and contract according to the force conditions. Specifically, if a certain side of the fixed disk 2193 touches a higher protrusion, the corresponding telescopic sleeve rod 2194 will be compressed, while the telescopic sleeve rods 2194 at other positions will remain relatively stable or make corresponding fine adjustments to ensure that the fixed disk 2193 can fit the seabed surface as much as possible. The adaptive adjustment mechanism effectively buffers the impact on the driving component 210 caused by the uneven seabed, protects the normal movement of the driving rod 211 on the fixing member 21, avoids damage due to excessive local force, enables the fixed disk 2193 to better fit the seabed surface of various complex terrains, and enhances the stability and reliability of the entire driving component 210 on the seabed.

[0057] As Figure 2 shown, an anti-slip rubber pad 2196 is installed in the middle of the bottom of the hull structure 1, and the anti-slip rubber pad 2196 has a long-shaped structure;

[0058] It should be noted that the long-shaped structural design enables the anti-slip rubber pad 2196 to better fit the seabed surface with different shapes and undulations. Whether encountering small protrusions, depressions or relatively gentle slopes, the long strip-shaped rubber pad can form closer contact with the seabed surface through its own elastic deformation, giving full play to its anti-slip function and enhancing the adaptability of the floating building under various complex seabed terrain conditions.

[0059] As Figure 7 shown, a linear-arrayed avoidance groove 221 is formed at the bottom of the adjusting plate 11. A reverse flow plate 222 is rotatably connected to the left end of the avoidance groove 221. A torsion spring 223 is connected between the top wall of the avoidance groove 221 and the reverse flow plate 222. The left ends of the adjusting plate 11 and the hull structure 1 are both provided with bevel edges, and the combination of these bevel edges forms a V-shaped structure. The V-shaped structure is like a natural flow deflector, which can effectively guide the oncoming tide to both sides.

[0060] It should be noted that when the adjusting plate 11 rotates at different angles on the hull structure 1 due to factors such as seabed inclination, the torsion spring 223 between the top wall of the avoidance groove 221 and the reverse flow plate 222 is twisted to store elastic potential energy. When the angle change of the adjusting plate 11 reaches a certain degree, the torsion spring 223 releases the spring potential energy, driving the reverse flow plate 222 to rotate around the left end of the avoidance groove 221. The adjusting plate 11 drives the reverse flow plate 222 to rotate to a specific angle, making the auxiliary plate 22 form a 30-degree angle with the adjusting plate 11. When the tide impacts, the reverse flow plate 222 changes the direction of the tide, guiding the water flow to generate an impact force on the inclined hull structure 1. Through the impact force generated by guiding the tide by the reverse flow plate 222, the frictional force between the hull structure 1 and the seabed is increased, significantly improving the stability of the hull structure 1 on the seabed.

[0061] As Figure 3 and Figure 8 shown, a shock-absorbing seat 231 is installed at the top of the adjusting plate 11. An activity groove is formed inside the shock-absorbing seat 231. Shock-absorbing spring rods 232 are installed around the inside of the activity groove. The bottom wall of the activity groove is connected by a slide rail to a shock-absorbing plate 233 that is slidably connected to the shock-absorbing spring rods 232. A universal joint 234 connected to the anchor chain is installed at the top of the shock-absorbing plate 233. The other end of the anchor chain is fixedly connected below the compartment seat 12.

[0062] It should be noted that when the compartment seat 12 generates vertical displacement or vibration due to factors such as sea waves and water flow, the compartment seat 12 floats up, and its own gravity is transmitted through the anchor chain. The buoyancy of the compartment seat 12 keeps the anchor chain in a taut state. The shock-absorbing plate 233 will slide up and down along the slide rail in the activity groove as the compartment seat 12 moves. During this process, the shock-absorbing spring rods 232 around will expand and contract according to the displacement of the shock-absorbing plate 233. The shock-absorbing system composed of the shock-absorbing spring rods 232 and the shock-absorbing plate 233 can effectively buffer the vibration and impact force transmitted from the compartment seat 12 to the adjusting plate 11. The setting of the universal joint 234 makes the connection between the anchor chain and the shock-absorbing seat 231 more flexible, avoiding excessive wear or breakage of the anchor chain due to improper angles, and improving the reliability of the connection between the compartment seat 12 and the adjusting plate 11.

[0063] The working principle of the present invention is as follows: for the floating building used in island reefs, during use, after the floating building sails to the designated position, it sinks through the water inlet structure inside the hull structure 1. The right end of the hull structure 1 sinks first along the direction of the island reef. When the hull structure 1 sinks and contacts the seabed, the passive block 219 touches the bottom first, and after receiving the reaction force from the seabed, it moves into the sleeve 218, compressing the expansion spring plate 2191. The movement of the passive block 219 is transmitted through the steel rope bypassing the first roller 216 and the second roller 217, prompting the spring of the spring compression plate 213 to release energy, pushing the driving rod 211 to move downward along the sliding channel of the fixed part 21. The driving rod 211 drives the driving rotating plate 212 to move, and then makes the auxiliary plate 22 rotate radially around the rotating shaft connected to the fixed part 21, finally driving the three groups of push claw parts 24 to move radially on the seabed to achieve radial fixation, enhancing the stability of the floating building on the seabed. When the seabed contacts the inclined island reef and the hull structure 1 tilts, the angle sensor installed on the hull structure 1 detects the angle of the adjusting plate 11 and feeds back the information. The hydraulic push rod 25 reacts according to the feedback information. The hydraulic push rod 25 drives the adjusting plate 11 to rotate until the adjusting plate 11 is horizontal on the seabed, ensuring the stability of the floating building on the inclined seabed, and at the same time enabling the anchor chain on the adjusting plate 11 to apply force evenly to the compartment seat 12;

[0064] The V-shaped structure formed by the adjusting plate 11 and the hypotenuse at the left end of the hull structure 1 can initially guide the tidal current. At the same time, the reverse flow plate 222 in the avoidance groove 221 at the bottom of the adjusting plate 11 rotates driven by the torsion spring 223 when the adjusting plate 11 rotates, making the auxiliary plate 22 form a 30-degree angle with the adjusting plate 11, further guiding the tidal current to impact the hull structure 1, increasing the friction between the hull structure 1 and the seabed, and enhancing the stability. When the compartment seat 12 has a vertical displacement or vibration due to waves, etc., the shock-absorbing spring rod 232 expands and contracts to buffer the vibration and impact force. The universal joint 234 ensures the flexible connection of the anchor chain, avoiding excessive wear or breakage and improving the connection reliability.
