Description

Technical Field

[0001] The present invention relates to a deep - water wharf structure, specifically a frame - enhanced ecological high - pile wharf integrating functions such as power generation, wave dissipation, water body exchange and biological exchange. Background Art

[0002] With the continuous enhancement of people's awareness of ecological environment protection, building green ecological ports has become an inevitable way for ports to improve their core competitiveness and achieve sustainable development.

[0003] Traditional open - type wharf structures are widely used in many ports at home and abroad due to their small wave reflection and good ecological functions. However, the open characteristics of traditional high - pile wharf structures result in poor wave - dissipating performance. To meet the ship mooring stability conditions, their applications are often limited to ports with relatively stable water flow conditions and protected by breakwaters. And for pile - type open - type breakwaters, due to the limited water - entry depth of their wave - retaining plates, they are only applicable to sea areas with relatively small wave lengths. Therefore, it is of great significance to develop a hydraulic structure that can serve as both a breakwater and a wharf under long - period wave conditions;

[0004] The development of offshore clean energy has gradually become a research hotspot for scholars at home and abroad. So far, relatively mature theoretical research and engineering practical applications have been achieved. For example, typical "sea snake - type hydraulic generators", "oscillating water column generators" and "overtopping generators". However, the functions of the power generation systems in the above - mentioned projects are relatively single, and the economic benefits need to be improved. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the above - mentioned background art and provide a high - pile ecological wharf structure that can also serve as a breakwater and generate electricity. The present invention combines the jacket with the high - pile wharf piles, strengthening the integrity of the high - pile structure. And the setting of the jacket can reduce the construction difficulty of the piles, improve the construction accuracy of pile driving, and increase the service life of the piles. To improve the disadvantage of poor wave - dissipating performance of traditional high - pile wharves, the present invention is provided with a power generation system and perforated wave - dissipating plates in the space between the piles. While the power generation system cuts down wave energy, it can convert tidal, water flow and wave energy into electric energy. The wave - dissipating plates gradually weaken the energy carried by the waves through staggered openings. The technical solutions are as follows:

[0006] A multifunctional frame - enhanced ecological high - pile wharf, each unit of which comprises four major parts: frame - type piles, a power generation system, wave - dissipating plates and the upper wharf structure, and is characterized in that

[0007] Each pile foundation unit of the frame - type piles comprises piles, a jacket and pile caps. There are at least three piles, and a jacket serving as a protective layer is fixed outside each pile. And a pile foundation unit is formed into a frame structure through the mutual connection between the jackets;

[0008] A framed pile foundation unit comprises at least six pile foundation units arranged in pairs from the seaward side to the landward side, forming a seaward rectangular frame and an adjacent landward rectangular frame. A power generation system is arranged within the seaward rectangular frame, and the wave dissipating plate is arranged at the landward rectangular frame.

[0009] The power generation system includes a generator support and a power generation device. The generator support is used to connect the power generation device to the surrounding pile foundation units.

[0010] The wave dissipating plate includes at least two independent parts. Its top is fixedly connected to the upper structure of the wharf. Wave dissipating plate openings serving as openings for the exchange of organisms and water are provided on each wave dissipating plate, and the openings are staggered from each other.

[0011] Further, the wave dissipating plate includes three parts, and one of them is arranged at the landward end of the landward rectangular frame.

[0012] Further, the generator support is in a cross shape and is used to connect the power generation device to four different surrounding pile foundation units.

[0013] Further, artificial fish reefs are placed between the wave dissipating plates.

[0014] The beneficial effects of the present invention are as follows:

[0015] (1) The jacket can be used as the basis for construction positioning and guidance during piling, significantly reducing the construction difficulty. At the same time, one jacket connects four piles together, enhancing the integrity and durability of the high-piled wharf structure, improving the structure's ability to resist loads in all directions. Meanwhile, the jacket serves as a protective layer to prevent the part of the pile above the mud surface from being damaged by factors such as waves, ice edges, and organisms, improving the shortcomings of the traditional high-piled wharf pile foundation being prone to damage and difficult to repair.

[0016] (2) The power generation system has multiple functions: magnetic poles are arranged in the outer rotor, and vertical and horizontal coils are arranged in the inner stator. When the outer rotor rotates or moves up and down, it will cut the magnetic induction lines to generate current, realizing the conversion of mechanical energy and electrical energy. When water flow, tides, and waves drive the outer rotor to move, the energy of the marine environment is converted into electrical energy. At the same time, the support serving as the main structure installation foundation of the power generation device is in a cross shape, connecting different framed pile foundations, significantly enhancing the integrity of the structure.

[0017] (3) In the present invention, the openings of the double-layer wave dissipating plates on the sea-facing side are staggered from each other. The wave dissipating plates are cast in situ with the upper structure, improving the wave dissipation ability and the ability to resist vertical loads of the structure, and enhancing the integrity of the structure. The openings provide channels for water and organisms. Artificial fish reefs suitable for organisms to inhabit are arranged between the sea-facing side and the landward side wave dissipating plates, which are made of new eco-friendly materials, and can improve the biological passage rate and the biological density around the wharf.

Specific implementation manner

[0023] The present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0024] As Figure 1 shown, each unit of the novel wharf structure is composed of four major parts: a framed pile foundation, a power generation system, a wave dissipating plate, and the upper structure of the wharf. The present invention has strong comprehensiveness, and its structure integrates the characteristics of a wharf such as wave dissipation, power generation, ecological friendliness, berthing of ships, and loading and unloading of goods.

[0025] The framed pile foundation includes pile 1, jacket 2, and pile cap 3. The inner diameter of the jacket 2 is slightly larger than that of pile 1 in the pile foundation. During pile driving, the jacket 2 can play a guiding and positioning role. The jacket 2 can serve as a protective layer for pile 1, and each jacket 2 can connect four piles 1 to form a frame structure, enhancing the integrity and durability of the high-pile wharf structure, improving the ability of the structure to resist loads in all directions. At the same time, as a protective layer, the jacket avoids the part of the pile above the mud surface from being damaged by factors such as waves, ice edges, and organisms, improving the disadvantages of the traditional high-pile wharf pile foundation that is easy to damage and difficult to repair; As Figure 3As shown, the power generation system consists of a generator bracket 4 and a power generation device, and the power generation device consists of a lightweight blade 5, an outer rotor 9, a generator 10, and an inner stator 11. The power generation system has multiple functions: the lightweight blade 5 has a relatively small density, and its main structure changes significantly with the change of water level, and the blade with an arc is easier to rotate under the push of the water flow; first, the outer rotor 9 is fixed with the lightweight blade 5, and a magnetic pole is arranged in the outer rotor 9, and a vertical and horizontal coil is arranged in the inner stator 11. When the outer rotor 9 rotates or rises and falls, the coils in the inner stator 11 will cut the magnetic flux lines to generate The electric current realizes the conversion of mechanical energy into electrical energy. When the water flow, tide and wave drive the outer rotor to move, its energy is also reduced, which is useful for improving the stability of the mooring in the port. Secondly, the bracket 4, which is the installation foundation of the main structure of the power generation device, is in a cross shape, connecting different frame pile foundations, which significantly enhances the integrity of the structure. The wave-breaking board 6 is composed of three prefabricated concrete boards, and the openings of the three boards are staggered to enhance the wave-breaking performance of the structure. The openings 7 of the wave-breaking board serve as openings for the exchange of organisms and water bodies. Artificial fish reefs 8 are placed between the wave-breaking boards 6 to improve the ecological friendliness of the structure. Figure 4 As shown, the upper structure includes a cross beam 12, a longitudinal beam 13, a panel 14, a bollard 15, and a rubber fender 16. The main functions of this part are to allow ships to dock and load and unload cargo.

[0026] A construction method of a multifunctional frame-enhanced ecological high-pile dock structure includes the following steps: first, the conductor frame 2 is positioned by a barge, and is towed to a predetermined position for installation; the guiding effect of the hollow conductor frame is used to drive piles 1; a cast-in-place pile cap 3 is used to complete the construction of the frame pile foundation; the conductor frame serves as a protective layer to prevent the part of the pile located above the mud surface from being damaged by factors such as waves, ice spikes and organisms; a bracket 4 of a power generation system is fixed to a preset bracket connection on the conductor frame; the remaining facilities (5, 9, 10, 11) of the power generation device are installed on the basis of the bracket; a magnetic pole is arranged in an outer rotor 9, and vertical and horizontal coils are arranged in an inner stator 11. When When the outer rotor 9 rotates or rises and falls, it will cut the magnetic flux lines to generate current, realizing the conversion of mechanical energy into electrical energy; a wave-breaking board 6 is installed between the pile foundations on the back sea side, the lower end of the wave-breaking board is sunk into the mud surface, and the upper end and the upper structure are cast in situ to resist the vertical load. Artificial fish reefs 7 are placed between the wave-breaking boards. The openings of the wave-breaking boards are staggered so that the waves are reflected multiple times and weakened here, thereby improving the wave-breaking capacity of the structure. The artificial fish reefs 8 are made of eco-friendly materials, which can increase the biological passage rate and biological density around the dock; the dock superstructure (12, 13, 14) is cast in situ to complete the construction of the main structure, and then the dock ancillary facilities (15, 16) are installed.
