Description

Technical Field

[0001] This invention relates to the field of nearshore floating structures, and in particular to a wave-dissipating and power-generating integrated floating platform based on tires and bamboo. Background Technology

[0002] Floating platforms are increasingly used in nearshore shallow seas, lakes, and aquaculture areas. However, existing floating platforms are mostly constructed of steel or marine engineering concrete, which results in high costs, heavy weight, poor corrosion resistance, and long construction periods. Furthermore, traditional fixed or simple floating structures have limited functionality, lack effective wave protection capabilities, and typically rely on external power supplies, making them less environmentally friendly and energy-efficient.

[0003] Traditional floating platforms have separate structures and functions. Wave damping facilities, power generation devices, and the main platform are often constructed independently, resulting in low system integration, large footprint, and high construction costs. Platform attitude control mostly relies on passive adjustment or rigid connections, making it difficult to respond to dynamic tilting caused by waves in real time and actively, which affects operational safety and comfort. Summary of the Invention

[0004] Purpose of the invention: In order to overcome the shortcomings of the prior art, the present invention provides a wave-damping and power-generating integrated floating platform based on tires and bamboo.

[0005] Technical solution: The wave-dissipating and power-generating integrated floating platform based on tires and bamboo provided by this invention includes: a main platform system, a buoyancy system, a power generation system, and an energy dissipation system; The main platform system is deployed on the outer side of the coastline and consists of multiple platform units flexibly spliced ​​together. The main platform system is a multi-layered stacked structure, consisting of an anti-slip walking platform, a foam board buoyancy layer, an upper bamboo pole grid, an adjustable water tank, a lower bamboo pole grid, and a bottom buffer buoyancy layer from top to bottom; the foam board buoyancy layer, the adjustable water tank, and the bottom buffer buoyancy layer constitute the buoyancy system. The power generation system is moored to the wave-facing side of the main platform system via mooring cables and transmits power and signals to the main platform system via flexible umbilical cables; The main platform system is equipped with a spiral wave-dissipating device on its outer periphery. The spiral wave-dissipating device and the bottom buffer buoyancy layer constitute an energy dissipation system.

[0006] Furthermore, each of the adjacent platform units is equipped with a connecting crossbar at the splicing point, and multiple tires are fitted onto the two adjacent connecting crossbars to achieve flexible splicing of adjacent platform units.

[0007] Furthermore, the anti-slip walking platform uses a high-density polyethylene anti-slip plate with added UV-resistant masterbatch, and the surface is decorated with anti-slip textures. The outer perimeter is formed by vertical anti-corrosion bamboo poles to form a fence handrail structure. The upper and lower bamboo pole grids are both rigid mesh structures formed by orthogonally arranging and fixing anti-corrosion bamboo poles. The outer perimeters of the upper and lower bamboo pole grids are connected to form a wrap around the adjustable water tank.

[0008] Furthermore, the foam board buoyancy layer is made of closed-cell foamed polypropylene foam board, which is formed by cold pressing multiple layers of single boards together with polyurethane adhesive. The foam board buoyancy layer extends beyond the outer contour of the adjustable water tank.

[0009] Furthermore, the adjustable water tank includes four diagonally independent water tanks, each equipped with a water inlet / outlet device controlled by a controller, and all water tanks are interconnected. Each water tank is equipped with a tilt sensor. When any tilt sensor detects a tilt angle exceeding a threshold, the controller controls the higher water tank to drain water into the lower water tank.

[0010] Furthermore, the bottom buffer buoyancy layer includes a frame structure formed by fixing horizontal and vertical anti-corrosion bamboo poles, and tire pieces of equal width cut from the tire are spliced ​​together end to end along the horizontal anti-corrosion bamboo poles to form a continuous spiral curved surface, with the concave surface of the tire pieces facing the direction of the waves.

[0011] Furthermore, the power generation system includes a barrel-shaped buoyancy base consisting of multiple layers of stacked tires filled with closed-cell foam. A central rotating shaft is provided in the middle of the buoyancy base as a primary rotating shaft. The upper end of the central rotating shaft is connected to a top platform via a waterproof thrust bearing. A permanent magnet generator is provided on the top platform. The generator stator is fixed to the top platform, and the rotor is fixed to the central rotating shaft. Multiple branch rods are radially connected to the outer circumference of the central rotating shaft. Each branch rod is connected downward to a branch rotating shaft. Multiple tires are axially connected to the branch rotating shafts to form a secondary rotating structure. The bottom of all the branch rotating shafts is connected to the same ring structure via a rotating shaft.

[0012] Furthermore, the main platform system is also equipped with a spiral wind power generation device on top, which together with the power generation system constitutes a multi-energy complementary power supply system.

[0013] Furthermore, the spiral wave-damping device is consistent with the transverse anti-corrosion bamboo pole structure of the bottom buffer buoyancy layer, and is formed by annular tire pieces of equal width forming a spiral curved surface, with the tire pieces connected end to end in an inclination angle of 15°~25°.

[0014] Beneficial effects: Compared with the prior art, the significant advancements of this invention are as follows: 1. The main materials of the platform can be waste tires and renewable bamboo, realizing the resource utilization of solid waste. The engineering cost is much lower than that of an all-steel structure platform, and the marine corrosion problem of steel is avoided. 2. It integrates functions such as floating platform, active adjustable attitude control, wave reduction and multi-source power generation, solving the problem that a single-function platform needs to be equipped with multiple auxiliary facilities; 3. The designed tire spiral wave-damping structure can absorb waves through elastic deformation, generate turbulence from the pores, and lift the waves along the spiral path, reducing the wave height by 35% to 40%, effectively protecting the safety of the platform body. 4. Four independent water tanks - fuzzy PID control system, which can dynamically and quickly respond to platform tilt and quickly correct the tilt angle, providing a stable working surface for personnel; 5. The plum blossom pile-type double-rotating power generation device can not only capture the overall rotational energy of the main body with the large waves, but also the tires on the multiple branches can capture the swaying kinetic energy of the local secondary waves. The cascaded rotation drives the generator together, and the power generation efficiency is significantly improved compared with the single-stage device. Attached Figure Description

Detailed Implementation

[0016] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 and Figure 2 The wave-dissipating and power-generating integrated floating platform based on tires and bamboo shown includes: main platform system 1, buoyancy system 2, power generation system 3, and energy dissipation system 4.

[0018] The main platform system 1 is deployed on the outer side of the coastline and consists of multiple platform individuals that are flexibly spliced ​​together. Each adjacent platform individual is equipped with a connecting crossbar at the splicing point. Multiple tires are fitted onto two adjacent connecting crossbars to achieve flexible splicing of adjacent platform individuals, which not only ensures the firmness of the connection, but also ensures the movement space between platform individuals through the internal movement margin of the tires.

[0019] The main platform system 1 is a multi-layer stacked structure, consisting of an anti-slip walking platform 101, a foam board buoyancy layer 102, an upper bamboo pole grid 103, an adjustable water tank 104, a lower bamboo pole grid 105, and a bottom buffer buoyancy layer 106 from top to bottom; the foam board buoyancy layer 102, the adjustable water tank 104, and the bottom buffer buoyancy layer 106 constitute the buoyancy system 2.

[0020] The anti-slip walking platform 101 uses a high-density polyethylene anti-slip plate with added UV-resistant masterbatch, with a thickness of not less than 10mm. The surface has 5-10mm protruding anti-slip strips with a long side spacing of 5-10cm and a short side spacing of 10-20cm, and cross anti-slip patterns. Its dry friction coefficient is ≥0.6 and wet friction coefficient is ≥0.4. The outer perimeter is formed by vertical anti-corrosion bamboo poles to form a fence handrail structure. The upper bamboo pole grid 103 and the lower bamboo pole grid 105 are both rigid mesh structures formed by anti-corrosion bamboo poles arranged orthogonally 1.2-1.5m above the platform and fixed with stainless steel clamps. The outer perimeter of the upper bamboo pole grid 103 and the lower bamboo pole grid 105 are connected to form a wrap around the adjustable water tank 104.

[0021] The foam board buoyancy layer 102 is made of closed-cell foamed polypropylene foam board, which is composed of multiple layers of single boards cold-pressed together with polyurethane adhesive. It has a density of 35~40 kg / m³, a compressive strength ≥200 kPa, a water absorption rate ≤1%, and a closed-cell rate ≥95%, providing 60%~70% of the platform's total buoyancy. The foam board buoyancy layer 102 extends beyond the outer contour of the adjustable water tank 104. The total thickness of the foam board is not less than 40 cm, and the joints between the single boards are staggered. Each side of the foam board extends 10~15 cm beyond the water tank below, and the joints between the boards are filled with waterproof sealant. The outer perimeter of each foam board is entirely covered with a high-density polyethylene rigid protective shell with a thickness of not less than 10 mm. The edge plates of the protective shell extend downwards to form an overlapping dike with a height of not less than 5 cm.

[0022] The adjustable water tank 104 is a food-grade polyethylene rotationally molded tank with a wall thickness of not less than 10mm and a thickness of 80-100cm. It is divided into four diagonally spaced smaller tanks, each equipped with a DN50 inlet with a filter screen located at the top of the tank, connected to the water pump outlet pipe, and no longer directly connected to external water bodies. A DN50 outlet with an electric gate valve is located at the center of the bottom of the tank, connected to the water pump suction port via a three-way valve. After pumping water, it is discharged to another tank or externally. A DN40 drain outlet is located at the top, with a detachable DN25 suction pipe inserted from the top equipment compartment to the lowest point of the tank bottom. When drainage is required, a portable diaphragm pump is used to draw water from the top. An immersion-type liquid level sensor with an accuracy of ±1cm~±2cm is inserted through the top opening, and the cable is led out from the top multi-functional riser. A DN100 316 stainless steel riser is set in the center of the water tank to provide support. When any sensor detects that the platform tilt angle is ≥3°, the PLC controller automatically fills water into the water tank at the lower position and drains water from the water tank at the higher position until the platform tilt angle is restored to ≤1°.

[0023] like Figure 3As shown, the bottom buffer buoyancy layer 106 includes a frame structure formed by fixing transverse and longitudinal anti-corrosion bamboo poles. Annular tire pieces 106-1 of equal width, cut from tires, are sequentially joined end-to-end along the transverse anti-corrosion bamboo poles to form a continuous spiral surface, with the concave surface of the tire pieces facing the wave direction. The wide annular tire pieces 106-1 are obtained by cutting off the inner bead of a waste tire and then cutting it in half radially.

[0024] like Figure 4 and 5 As shown, the power generation system 3 is moored to the wave-facing side of the main platform system 1 via mooring cables and transmits power and signals to the main platform system 1 via flexible umbilical cables. The power generation system 3 includes a rotating power generation device consisting of a multi-layered stacked tire and a barrel-shaped buoyancy base 301 filled with closed-cell foam. A central rotating shaft 302 is located in the middle of the buoyancy base 301 as the primary rotating shaft. The upper end of the central rotating shaft 302 is connected to the top platform 304 via a waterproof thrust bearing 303. A permanent magnet generator is located on the top platform 304. The generator stator is fixed to the top platform 304, and the rotor is fixed to the central rotating shaft 302. Multiple branch rods 305 are radially connected to the outer periphery of the central rotating shaft 302. Each branch rod 305 is connected downward to a branch rotating shaft 306. Multiple tires are axially strung on the branch rotating shaft 306 to form a secondary rotating structure. The bottom of all branch rotating shafts 306 are connected to the same ring structure via rotating shafts. The flexible umbilical cable integrates power cables and signal cables. One end is led out from the permanent magnet generator, and the other end is connected to the waterproof electrical cabinet of the floating platform body. The suspended section of the umbilical cable is floated or suspended underwater by a buoy, and a slack length greater than 1.5 times the maximum relative displacement is reserved.

[0025] The main platform system 1 is also equipped with a spiral wind power generation device on top, which together with the power generation system 3 forms a multi-energy complementary power supply system.

[0026] The main platform system 1 is equipped with a spiral wave-dissipating device 401 on its outer periphery. The spiral wave-dissipating device 401 and the bottom buffer buoyancy layer 106 constitute the energy dissipation system 4.

[0027] The spiral wave-damping device 401 is consistent with the transverse anti-corrosion bamboo pole structure of the bottom buffer buoyancy layer 106. It is formed by annular tire pieces of equal width 106-1 forming a spiral curved surface. The tire pieces are connected end to end in an inclination angle of 15°~25°.

[0028] The following steps can be taken during construction: Step 1: Cut, drill, soak or coat with tung oil to prevent corrosion of all bamboo poles and let them dry; sort and clean the waste tires, keep the intact tires for later use, cut some tires according to the requirements of the spiral blades and power generation device, and coat the cut ends with anti-rust paint; check and count all metal connectors, bearings, valves, sensors, PLC controllers and generator sets. Step 2: Make the upper and lower bamboo pole grids; install bearings on the central large bamboo pole and branch bamboo poles of the power generation device, and complete the fitting of tires to bamboo poles to assemble the central rotating assembly and branch rotating units; prefabricate four independent water tanks, PE rotational molding, with internal cross-shaped partitions, and each small water tank is reserved with inlet and outlet, sewage outlet and liquid level sensor socket, and a stainless steel riser is installed in the center. Step 3: Install the upper bamboo pole grid to cover the water tank, and use bolts to fasten it to the lower grid and bottom frame to form a rigid clamp; lay EPP / EPP foam boards, and use polyurethane glue to cold press and overlap the multiple layers of boards, with the splicing seams staggered and filled with waterproof sealant; cover the outer perimeter of each foam board with a ≥10mm thick HDPE protective shell, and extend the protective shell edge plate downwards by ≥5cm to form an overlapping dike to cover the lower connection seam; Step 4: Hoist the water tank to the center of the lower grid, leaving a 1-2cm adjustment gap on all four sides, and fix the central upright to the grid; install a DN50 inlet with a filter screen on the top of each independent small water tank, a DN50 outlet with an electric gate valve on the bottom, a DN25 drain outlet with a pipe at the top, and a submersible level sensor with an accuracy of ±1-2cm; connect all sensor signals to the PLC controller, and connect the controller output to the inlet solenoid valve, drain gate valve, and water pump of each water tank; set the leveling logic as follows: when the tilt angle is ≥3°, automatically fill water into the lower water tank and drain water from the higher water tank until the tilt angle is ≤1°.

[0029] Step 5: Lay out the following layers in sequence: bottom layer of bamboo spiral tire pad cushioning buoyancy layer, bottom layer of bamboo grid, water tank, top layer of bamboo grid, high-strength foam board buoyancy layer, and anti-slip walking platform. Secure each layer with stainless steel bolts and install the fence handrail uprights simultaneously. Install vertical anti-corrosion bamboo handrails along the four sides of the platform (1.2~1.5m above the platform, spaced 1.2~1.5m apart). Use horizontal bamboo poles with a diameter ≥8cm as crossbars at the top and middle, and fix them with 304 stainless steel clamps. Step Six: Fix the prepared tire cutting pieces at a 15°~25° angle and a 30~40cm pitch to both sides of the main platform and the bottom horizontal bamboo poles, leaving a 10~15cm gap between adjacent tire pieces; each tire piece is fixed to the upright with galvanized iron wire and M8 stainless steel clamps to form a continuous spiral surface. The concave surface faces the direction of the waves, and ensure that the spiral is continuous, the angle is consistent, and the tire pieces are firmly fixed without loosening or flipping. Step 7: For the plum blossom bamboo pole tire string rotating power generation device, tow the bottom buoyancy base (5 layers of tire stack + closed-cell foam) to a position 3-8m on the wave-facing side of the platform; install the lower bearing seat of the central bamboo pole to the base flange, and connect the upper bearing seat to the top bamboo platform; extend 5 branch bamboo poles evenly along the upper circumference of the central bamboo pole (plum blossom arrangement), with waste tires strung vertically through the branches, and fixed with bearings at both ends; connect the top of the central bamboo pole to the permanent magnet generator rotor through a coupling, and fix the stator to the top platform; connect the bottom of the power generation device to the bottom load-bearing frame of the platform with mooring cables, with a slack length reserved for ≥1.5 times the maximum relative displacement; Step 8: Connect the water level sensor, valves, and water pump of the water tank to the PLC controller and set the leveling program; connect the rotor of the power generation unit to the generator and fix the stator; complete the waterproof wiring and installation of all electrical equipment and wind turbines. Step 9: The electrical energy output from the wave energy generator and the spiral wind power generator is fed into the energy storage battery pack in the waterproof electrical cabinet. A controller and energy management module are configured to realize the automatic switching and parallel power supply of wave energy, wind energy and solar energy, so as to ensure stable power supply under different sea conditions and sunlight conditions, prioritize the power supply to the platform itself, and store or send out excess power. Step 10: Tow the assembled main platform to the designated water area, use a slipway or crane vessel to push the platform into the water as a whole, and check the buoyancy and draft. Place concrete anchor blocks (each weighing ≥200kg) at the designated anchor position, connect the bottom mooring lugs of the platform with anchor chains or high-strength nylon cables, and adjust the length of the anchor chains to ensure that the horizontal mooring radius of the platform is ≥2 times the water depth. Step 11: Based on different simulated wave angles in actual water areas, calibrate the liquid level sensors and PID parameters of the PLC controller in the four independent water tanks to verify the response time and accuracy of the platform tilt angle recovering from ≥3° to ≤1°. Step 12: Integrate the generator power cable and signal cable into a flexible umbilical cable, cover it with a wear-resistant sheath, and tie floats to the suspended section every 2-3m to make it float or make it sink 1-2m below the water surface in an S-shaped catenary; reserve a slack length ≥1.5 times the maximum relative displacement; Step 13: Check the integrity of all bamboo poles, tires, foam boards, and metal connectors to ensure there is no corrosion, cracks, or looseness. Step Fourteen, Overall Platform Performance Evaluation Test: Test the platform's buoyancy stability, wave dissipation efficiency, power generation system output power, and wind and wave resistance under calm water and wave conditions, complete the overall functional acceptance of the platform, and put it into use.
