Description

Technical Field

[0001] This utility model relates to the field of marine structure technology, and in particular to a marine structure buffer device. Background Technology

[0002] In the field of marine engineering technology, marine structures built on coral sand foundations face severe stability challenges. Coral sand foundations have unique physical characteristics such as loose particles, high porosity, and low shear strength, resulting in relatively weak foundation bearing capacity. Under long-term exposure to wave loads, tidal forces, and potential seismic forces, these dynamic loads can be easily transmitted to the superstructure, causing significant vibrations and uneven settlement, seriously threatening the safety and durability of the structure.

[0003] While existing technologies employ elastic elements such as rubber blocks for cushioning, the cushioning mechanism is relatively simple and has limited energy dissipation capacity. It cannot fully absorb and disperse the enormous impact energy, causing the structure to still bear significant impact forces. Over time, this can easily lead to structural cracking, tilting, and even collapse at the connection between the foundation and the structure. Therefore, there is an urgent need for a new type of foundation device that can effectively mitigate vibration, adapt to ground settlement, and be flexible in installation. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a buffer device for marine structures that can improve shock absorption and adapt to ground settlement.

[0005] A marine structure buffer device according to an embodiment of the present invention includes: The base is placed on a coral sand foundation. The outer perimeter of the base is equipped with multiple fixing rods that can be inserted into the coral sand foundation. The base is equipped with multiple buffer mechanisms, each of which has a damper. The base is movably connected to the pedestal. The base includes a mounting plate for installing structures. A buffer mechanism is supported on the bottom of the mounting plate. The pedestal is provided with multiple guide rods, which are movably inserted into the circumference of the base. Buffer sleeves are fitted around the outer periphery of the guide rods.

[0006] A marine structure buffer device according to an embodiment of the present utility model has at least the following beneficial effects: This embodiment includes a base and a pedestal. The base is placed on a coral sand foundation, and multiple fixing rods are provided around its outer perimeter to prevent slippage. Multiple buffer mechanisms are provided on the pedestal. The pedestal is movably connected to the base and includes a mounting plate for installing the structure. The buffer mechanisms are supported at the bottom of the mounting plate, providing shock absorption and minimizing vibration energy transmission to the structure. Simultaneously, the buffer mechanisms have dampers to reduce the speed of the pedestal's lifting and lowering movement on the base. When the base settles with the coral sand foundation, it prevents rapid swaying, thus improving the stability of the structure. The base has multiple guide rods that are movably inserted around the pedestal, guiding the pedestal's lifting and lowering movement and improving stability during movement, reducing swaying. A buffer sleeve is fitted around the outer perimeter of the guide rods. When the bottom of the pedestal contacts the buffer sleeve, it further absorbs vibration, reducing vibration energy transmission to the structure, thereby improving the structure's stability and lifespan.

[0009] According to some embodiments of the present invention, the mounting plate is provided with a connecting block, the connecting block including a clamping plate, which can clamp onto the outer periphery of the structure to achieve the fixation of the structure.

[0010] According to some embodiments of the present invention, the connecting block further includes a connecting plate and a support plate. The support plate is installed on the connecting plate and supports the side of the clamp away from the structure, so as to improve the structural strength of the connecting block and thereby improve the installation stability of the structure.

[0023] A marine structure buffer device according to an embodiment of the present invention is mainly applied to various marine structures built on coral sand foundations, such as lighthouses, wind turbine foundations, and small platforms. It aims to effectively mitigate the impact and vibration caused by dynamic loads such as waves, tides, and earthquakes, and can adapt to possible settlement of the coral sand foundation, thereby ensuring the long-term stability and safety of the superstructure.

[0024] Reference Figures 1 to 5 The marine structure buffer device mainly consists of a base 100 and a base 110. The base 100, serving as the bottom support of the entire device, is placed directly on the treated coral sand foundation surface. The base 100 has a frame structure with sufficient rigidity and area to distribute the upper load. To ensure a reliable connection between the base 100 and the loose coral sand foundation and prevent slippage under horizontal loads, multiple fixing rods 101 are installed around the outer periphery of the base 100. These fixing rods 101 are preferably steel rods with pointed or barbed ends to facilitate manual or mechanical vertical pressing or driving into the coral sand foundation. Through the friction and mechanical interlocking force between the fixing rods 101 and the coral sand particles, the base 100 is anchored to the foundation.

[0025] At the bottom of the base 100, multiple crossbars 109 are fixedly connected. The crossbars 109 extend along the width of the base 100, increasing the contact area with the ground and improving stability. Furthermore, the crossbars 109 have multiple connecting holes 118, providing additional insertion points for the fixing rods 101. The fixing rods 101 can pass through these connecting holes 118 before being inserted into the ground, making the base 100, crossbars 109, and fixing rods 101 form a more integrated anti-slip system, significantly enhancing the foundation's resistance to overturning and slippage in complex marine environments.

[0026] The base 100 is connected to the base 110 via a buffer mechanism 102. Preferably, at least two buffer mechanisms 102 are provided and spaced apart along the length of the mounting plate 111 of the base 110 to ensure uniform support and stability. Each buffer mechanism 102 includes a damper 103, a spring 104, and a mounting base 105. The mounting base 105 is fixedly mounted on the top surface of the base 100 by welding or bolting. The damper 103 is preferably a hydraulic shock absorber, with its bottom fixed to the mounting base 105 and its piston rod extending vertically upwards. The spring 104 is sleeved on the outer periphery of the damper 103, its bottom supported on the mounting base 105, and its top in contact with the top of the piston rod of the damper 103 or a connected component thereto. This combination of spring 104 and damper 103 in parallel integrates the advantages of spring in efficiently absorbing impact energy (converting kinetic energy into elastic potential energy) and damper 103 in dissipating energy and slowing down movement through friction via hydraulic medium, together forming a highly efficient buffer and shock absorption system.

[0027] The base 110 is movably connected to the base 100. The base 110 mainly includes a mounting plate 111 for directly mounting the structure and a frame 112 supporting the mounting plate 111. The frame 112 is typically welded from structural steel and has sufficient strength and rigidity. The two ends of the mounting plate 111 are fixedly mounted on the frame 112, providing a flat mounting surface for the structure. The top of the buffer mechanism 102, i.e., the top of the piston rod of the damper 103, is supported on the bottom of the mounting plate 111. In this way, the load of the upper structure is transferred through the mounting plate 111 to the spring 104 and the damper 103, and finally borne by the base 100.

[0028] To ensure that the base 110 can only move vertically relative to the base 100 smoothly during load bearing and shock absorption, without horizontal offset or torsion, this application provides guide rods 107. Specifically, a base plate 106 is fixedly installed on the base 100. The base plate 106 can be integrally formed with the base 100 or independently fixedly connected by welding. Around the base plate 106, preferably at the four corners, multiple vertically extending guide rods 107 are fixedly installed. The guide rods 107 are smooth cylindrical steel rods. Correspondingly, around the frame 112 of the base 110, insertion holes 113 are provided, corresponding one-to-one in number and position to the guide rods 107. The inner diameter of these insertion holes 113 is slightly larger than the outer diameter of the guide rods 107, allowing the guide rods 107 to slide precisely into the insertion holes 113. In this way, when the base 110 is about to move under the action of external forces such as wave impact, the sliding fit between the guide rod 107 and the socket 113 strictly restricts its movement trajectory, so that it can only rise and fall smoothly in the vertical direction, which greatly improves the stability and reliability of the buffering process.

[0029] A buffer sleeve 108 is also fitted around the outer periphery of each guide rod 107. The buffer sleeve 108 is preferably made of a flexible plastic material with good elasticity and corrosion resistance, such as polyurethane or rubber. The buffer sleeve 108 is fixed at a specific position on the guide rod 107, such as the lower middle part. When the base 110 moves downwards to a certain stroke, the frame 112 contacts the buffer sleeve 108. At this time, the buffer sleeve 108 absorbs and buffers the remaining impact energy through its own compression deformation, forming a second line of defense to prevent rigid impacts between metal parts.

[0030] The mounting plate 111 is provided with connecting blocks 114 for installing structures. Two connecting blocks 114 are provided, located at opposite ends of the mounting plate 111 along its length. Each connecting block 114 mainly includes a connecting plate 116, a support plate 117, and a pair of clamping plates 115. The connecting plate 116 is fixed to the upper surface of the mounting plate 111 by welding or high-strength bolts. The support plate 117 is vertically mounted on the connecting plate 116, serving to enhance rigidity. The pair of clamping plates 115 are arranged opposite each other, their lower parts connected to the connecting plate 116 and the support plate 117, and their upper parts forming clamping openings. The foundation legs or embedded parts of the structure can be placed between the two clamping plates 115 and then fastened by bolts passing through the clamping plates 115, thereby achieving reliable clamping of the structure. The support plate 117 is located on the side of the clamping plate 115 away from the structure, providing solid back support for the clamping process, preventing the clamping plate 115 from deforming under huge external forces, and greatly improving the stability and safety of the structure installation.

[0031] During installation, the base 100 is first hoisted to the predetermined position on the coral sand foundation. After leveling, multiple fixing rods 101 are passed through the connecting holes 118 on the outer perimeter of the base 100 and the crossbar 109, and forcefully driven into the coral sand foundation to complete the initial fixation of the base 100. Subsequently, the base plate 106, with the buffer mechanism 102 and guide rod 107 already installed, is fixed to the base 100. Next, the base 110, with the upper structure installed via the connecting block 114, is hoisted above the base 100, aligning the insertion hole 113 on the frame 112 with the guide rod 107, and slowly lowered until the bottom of the mounting plate 111 of the base 110 is supported by the damper 103 and spring 104 of the buffer mechanism 102.

[0032] When waves, tidal forces, or seismic loads in the marine environment act on the superstructure, the impact force is transmitted to the base 110. Under the impact force, the base 110 tends to move downwards. At this time, the spring 104 is compressed, absorbing a large amount of impact energy; simultaneously, the piston rod of the damper 103 is compressed and contracts, and the hydraulic oil inside generates great resistance through narrow channels, converting some of the mechanical energy into heat energy and dissipating it, thereby effectively slowing down the descent speed of the base 110 and smoothing the peak impact. The cooperation between the guide rod 107 and the socket 113 ensures that the entire buffering process is a smooth vertical movement, avoiding instability and deflection.

[0033] When the impact force weakens or disappears, the compressed spring 104 releases its stored elastic potential energy, pushing the base 110 to return to its original position. The damper 103 also plays a damping role in this process, preventing the base 110 from rebounding too quickly and causing oscillation.

[0034] This invention is also well-suited to address the potential long-term settlement of coral sand foundations. When foundation settlement causes the base 100 to descend, the superstructure, due to its massive mass and inertia, tends to maintain its original height. This relative movement results in the base 110 "rising" relative to the base 100. Specifically, the guide rod 107 slides downward relative to the insertion hole 113, while the damper 103 passively extends, and the compression of the spring 104 decreases. This automatic adjustment process compensates for the height loss caused by foundation settlement, prevents tilting or structural damage to the superstructure due to forced pulling, and maintains the levelness and stability of the structure.

[0035] In summary, this invention provides a stable foundation connection through the combination of the base 100 and the fixed rod 101, achieves efficient energy absorption and dissipation through the spring 104 and damper 103 in the buffer mechanism 102, ensures stability of movement through the cooperation of the guide rod 107 and the insertion hole 113, and achieves a reliable connection with the superstructure through the connecting block 114. The entire device is rationally designed, has a significant buffering effect, can effectively adapt to harsh marine environments and foundation conditions, and significantly improves the safety and service life of marine structures.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
