Technical Field
[0001] This invention relates to the field of waterborne operation platform technology, and in particular to a waterborne platform for photovoltaic installation on tidal flats. Background Technology
[0002] Developing photovoltaic projects in tidal flats is an important direction for expanding the application of clean energy, but its unique environment brings enormous construction challenges. The site is severely affected by daily tides, being submerged by several meters of seawater at high tide and exposed by low tide with some areas submerged in water up to 0.8 meters deep. The tidal flat surface is composed of deep silt with extremely low bearing capacity, making it extremely difficult for personnel and machinery to pass and operate, and prone to vehicles and people getting stuck. The transportation volume of photovoltaic modules, brackets, and other materials is enormous, and the isolation from the shore results in long transportation distances and high costs for secondary handling. Traditional construction methods rely heavily on brief tidal gaps and geological improvement, resulting in low efficiency, high safety risks, slow progress, and uncontrollable issues.
[0003] Therefore, there is an urgent need for a new type of floating platform for tidal flat photovoltaic installations to provide an effective solution to the shortcomings of existing technologies. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a floating platform for photovoltaic installation on tidal flats, in view of the above-mentioned problems.
[0005] The technical solution adopted in this invention is: a floating platform for photovoltaic installation on tidal flats, comprising: Multiple pipe piles are arranged in an array on the mudflats to form a supporting foundation; The work platform unit, located between multiple pipe piles, is used to provide a work platform above the mudflats; The floating component, located at the bottom of the work platform unit, can drive the work platform unit to float with the water level on the tidal flat; The adjustment component is detachably mounted on the top of the pipe pile and connected to the side of the work platform unit to adjust the height of the work platform unit.
[0006] Using the above-mentioned technical means, multiple pipe piles are used to form a support system on the mudflats. The work platform units deployed on the pipe piles form an effective work platform on the mudflats. The bottom of the work platform unit is equipped with a floating component, which allows the work platform unit to float automatically with the rise and fall of the water level, thereby avoiding being submerged during high tide and maintaining a stable working height during low tide. The height of the work platform unit can be further adjusted using the adjustment component.
[0007] In some embodiments, the system further includes a level sensor, a centralized controller, a distributed servo control module, and a communication network module. The level sensor, centralized controller, and distributed servo control module are all communicatively connected to the communication network module. The distributed servo control module is communicatively connected to the adjustment component. The work platform unit is equipped with a level sensor, which is used to acquire the level of the work platform unit and transmit it to the centralized controller via the communication network module. If the level does not meet the preset level threshold inside the centralized controller, the centralized controller sends a control command to the distributed servo control module. The distributed servo control module controls the corresponding adjustment component to adjust the level of the work platform unit based on the control command.
[0008] In some embodiments, the adjustment assembly includes a snap-fit component and a chain hoist. One end of the chain hoist is connected to the snap-fit component via a hook, and the snap-fit component can snap onto the top of the pipe pile. The other end of the chain hoist is connected to the side of the working platform unit via a hook.
[0009] In some embodiments, the snap-fit component includes a mounting base, a threaded sleeve, a bidirectional adjusting screw, and a wrench-shaped locking protrusion. The mounting base has a mounting hole that can cooperate with the hook, and a U-shaped groove that can be snapped into the top of the side wall of the pipe pile. The side wall of the mounting base facing away from the mounting hole is connected to a threaded sleeve with internal threads. A bidirectional adjusting thread is threaded between the threaded sleeves of a pair of mounting bases. The two ends of the bidirectional adjusting screw have external threads that are opposite to each other, and a wrench-shaped locking protrusion is provided in the middle of the bidirectional adjusting screw.
[0010] In some embodiments, the chain hoist is equipped with a tension sensor, which is connected to the communication network module. The tension sensor is used to detect the tension information of the chain on the chain hoist. If the tension information does not meet the preset tension threshold inside the central controller, the central controller sends a control command to the distributed servo control module. The distributed servo control module controls the corresponding chain hoist action based on the control command to adjust the tension of the chain hoist.
[0011] In some embodiments, the work platform unit includes a long side I-beam, a short side I-beam, a steel mesh, and a railing. Multiple short side I-beams are connected at intervals between a pair of long side I-beams. The frame formed by the long side I-beams and the short side I-beams is filled with steel mesh, and a railing is connected to the top of the long side I-beams.
[0012] In some embodiments, the floating component includes a float and a clamp. The side walls at both ends of the float are provided with a plurality of clamps that can be clamped onto the long side I-beam. Both the clamps and the long side I-beam are provided with bolt holes, and the bolt holes are fixed by bolt threads.
[0013] In some embodiments, a safety net is provided between adjacent work platform units.
[0014] The beneficial effects of this invention are: 1. Traditional construction methods require foundation treatment or temporary road construction in deep silt, resulting in high costs and low efficiency. This solution uses arrayed pipe piles as the supporting foundation, directly transferring the load to the deep bearing layer. Simultaneously, the work platform units are suspended above the mudflats, avoiding direct contact between personnel and equipment and the soft silt, fundamentally mitigating the risk of vehicles and personnel getting stuck. By installing floating components at the bottom of the work platform units, they can automatically float with the rise and fall of the water level, thus avoiding submersion during high tide and maintaining a stable working height during low tide. This significantly extends the operational window, eliminating complete reliance on the short low tide period. Adjustable components allow control of the suspension height of the work platform units during low tide. Multiple work platform units can serve as stable transfer and work surfaces, facilitating the centralized stacking and hoisting of large materials such as photovoltaic modules and supports, reducing reliance on shoreline channels, lowering the frequency and cost of secondary handling, and enabling a highly efficient direct water transport logistics model during high tide.
[0015] 2. The horizontal sensor monitors the levelness of the work platform unit in real time, and the tension sensor monitors the chain force. The monitoring data is transmitted to the central controller via the communication network module. The controller compares the measured values with preset thresholds. If the values exceed the limits, it sends a command to the distributed servo control module at the corresponding location. The servo module drives the electric chain hoist to automatically tighten or loosen until the platform is level and the force is balanced. This enables automatic lifting and lowering according to tidal changes, keeping the entire work platform in a horizontal state and ensuring the stability and safety of the work platform.

[0032] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.
[0033] Combination Figures 1 to 11As shown, this embodiment is a floating platform for photovoltaic installation on tidal flats, including multiple pipe piles 1, working platform units 2, floating components, and adjustment components. The multiple pipe piles 1 are arranged in an array on the tidal flat to form a supporting foundation. An adjustment component is detachably mounted on the top of each pipe pile 1, and the adjustment component is connected to the working platform unit 2. The working platform unit 2 provides a working platform above the tidal flat, and the adjustment component is used to adjust the height of the working platform unit 2. Specifically, in this embodiment, the pipe piles 1 are arranged in a rectangular array on the tidal flat, with the bottom of each pipe pile driven deep into the soil. Multiple working platform units 2 are arranged side-by-side, with adjacent working platform units 2 having aligned edges and detachably fixed connections.
[0034] According to the design drawings, a large number of pipe piles 1 were precisely driven into the deep, hard layer of tidal flat silt in a rectangular array. The pipe piles 1 constituted the permanent foundation support system of the entire platform, providing stable and reliable anchor points for the upper operation, and completely avoiding the problem of traditional machinery sinking due to insufficient surface bearing capacity.
[0035] In some implementation schemes, such as Figure 5 and Figure 6 As shown, the work platform unit 2 includes a long side I-beam 202, a short side I-beam 201, a steel mesh 203, and a railing 204. A pair of long side I-beams 202 are connected at equal intervals by multiple vertically arranged short side I-beams 201. The ends of the short side I-beams 201 are detachably connected to the long side I-beams 202 by bolts. The frame formed by the long side I-beams 202 and the short side I-beams 201 is filled with steel mesh 203. The tops of the two long side I-beams 202 are detachably connected to the railings 204 by bolts.
[0036] In this embodiment, each work platform unit 2 is pre-assembled on shore or at a temporary site. Modular prefabrication and on-shore assembly followed by overall transportation and installation improve efficiency. A robust planar steel frame is formed using long-side I-beams 202 as main longitudinal beams and short-side I-beams 201 as transverse beams. Steel matting 203 laid on this planar steel frame serves as the working surface, and railings 204 installed around the perimeter provide initial safety protection.
[0037] Furthermore, such as Figure 7 As shown, the floating component includes a float 205 and clamps 206. The side walls at both ends of the float 205 are provided with multiple clamps 206 that can be engaged with the long-side I-beam 202. Both the clamps 206 and the long-side I-beam 202 have bolt holes, and bolts are used for threaded fastening. Specifically, in this embodiment, each end of the float 205 has a pair of clamps 206. The top of the clamps 206 has a U-shaped structure to engage with the long-side I-beam 202. After the U-shaped structure of the clamps 206 engages with the long-side I-beam 202, it is fixed with bolts.
[0038] The float 205 is installed on the work platform unit 2 using clamps 206. The float 205 provides sufficient buoyancy for the entire work platform unit 2, enabling it to rise and fall with the tide. The platform floats during high tide, preventing it from being submerged or destroyed. The assembled platform unit can be towed or pushed to the designated work area by a small boat during high tide, relying on its own buoyancy. During installation, it is hoisted using a boat.
[0039] In some implementation schemes, such as Figure 3 and Figure 4 As shown, multiple work platform units 2 can be spliced horizontally or vertically. By laying multiple work platform units 2 side by side and connecting them with bolts, a wide work belt can be quickly formed. At the same time, safety nets 5 are installed between multiple rows of adjacent work platform units 2. The safety nets 5 can effectively prevent tools and materials from falling into the water and provide double protection for personal safety, solving the high-risk problem of water operations.
[0040] In some implementation schemes, such as Figure 8 and Figure 9 As shown, the adjustment assembly includes a snap-fit component and a chain hoist 3. One end of the chain hoist 3 is connected to the snap-fit component via a hook 301, and the snap-fit component can snap onto the top of the pipe pile 1. The other end of the chain hoist 3 is connected to the side of the working platform unit 2 via the hook 301. Specifically, in this embodiment, the chain hoist 3 is a conventional electric hoist.
[0041] Furthermore, such as Figure 10 and Figure 11 As shown, the snap-fit component includes a mounting base 4, a threaded sleeve 403, a bidirectional adjusting screw 404, and a wrench-shaped locking protrusion 405. The mounting base has a hanging hole 402 that can cooperate with the hook 301, and a U-shaped groove 401 that can be snapped onto the top of the side wall of the pipe pile 1. The side wall of the mounting base facing away from the hanging hole 402 is connected to a threaded sleeve 403 with internal threads. A bidirectional adjusting thread is threaded between the threaded sleeves 403 of a pair of mounting bases. The two ends of the bidirectional adjusting screw 404 have mutually opposite external threads, and a wrench-shaped locking protrusion 405 is provided in the middle of the bidirectional adjusting screw 404. Specifically, in this embodiment, the mounting bases 4 are arranged in pairs, and the two mounting bases 4 of the same pair are hung at the top port of the same pipe pile 1. The two mounting bases 4 of the same pair are welded with threaded sleeves 403, and a bidirectional adjusting screw 404 is threaded between the two threaded sleeves 403. A hexagonal wrench-shaped locking protrusion 405 is provided in the middle of the bidirectional adjusting screw 404.
[0042] During installation, a pair of hangers 4 are secured to the top of the pre-installed pipe pile 1 via U-shaped grooves 401 on both sides of the upper opening of the pipe pile 1. The pair of hangers 4 are connected by a bidirectional adjusting screw 404. When it is necessary to adjust the relative distance between the two hangers 4, a tool such as a wrench is used to engage the hexagonal wrench catch 405 in the middle of the screw and rotate it. When rotating the bidirectional adjusting screw 404, because the threads at both ends rotate in opposite directions, the two hangers 4 will be synchronously driven to move towards or away from each other along the screw. This function can be used to fine-tune the tightness of the hangers 4 on the pipe pile 1, ensuring that they are in the optimal stress state and can adapt to pipe piles 1 of different diameters within a certain range. Through the structure of being set in pairs and connected to each other, a stable whole is formed by clamping the top of the pipe pile 1, effectively preventing the risk of side overturning or slippage that may occur due to uneven stress on a single hanger 4, greatly enhancing the safety and reliability of the entire suspension system.
[0043] In this embodiment, the chain hoist 3 can be manually controlled. The hook 301 at the upper end of the chain hoist 3 is hung in the hanging hole 402 of the hanging seat 4 at the top of the pipe pile 1, and the hook 301 at the lower end is hung on the frame of the long side I-beam 202 of the working platform unit 2. The operator can observe the platform status, such as visually judging the tilt, judging by experience, or using simple tools such as a spirit level, and manually operate the electric switch of the chain hoist 3 to raise and lower the chain of the chain hoist 3, so as to accurately adjust the height of the working platform unit 2 above the water. When the tide rises, the platform floats with the water level, avoiding being submerged and impacted by the tide, ensuring the stability and safety of the platform. When the tide recedes, the platform is lowered to a suitable working height, and can even directly contact the mudflat surface.
[0044] In some implementation schemes, the water-based platform for photovoltaic installation on tidal flats also includes a level sensor, a centralized controller, a distributed servo control module, and a communication network module. The level sensor, centralized controller, and distributed servo control module are all communicatively connected to the communication network module. The distributed servo control module is communicatively connected to the adjustment components. A level sensor is installed on the work platform unit 2 to obtain the levelness of the work platform unit 2 and transmit it to the centralized controller via the communication network module. If the levelness does not meet the preset levelness threshold inside the centralized controller, the centralized controller sends a control command to the distributed servo control module. The distributed servo control module controls the corresponding adjustment components based on the control command to adjust the levelness of the work platform unit 2. Specifically, in this embodiment, the distributed servo control module is communicatively connected to the drive motor of the chain hoist 3.
[0045] Furthermore, the chain hoist 3 is equipped with a tension sensor, which is connected to the communication network module. The tension sensor is used to detect the tension information of the chain on the chain hoist 3. If the tension information does not meet the preset tension threshold inside the central controller, the central controller sends a control command to the distributed servo control module. The distributed servo control module controls the corresponding chain hoist 3 to adjust the tension of the chain hoist 3 based on the control command.
[0046] In this embodiment, the chain hoist 3 and the working platform unit 2 can also adopt intelligent closed-loop automatic control. The centralized controller is used to receive and process data from all tension and level sensors, generate motor control commands according to a preset control algorithm, and send the commands to each distributed servo control module through the system communication network. The distributed servo control module is used to receive motor control commands, drive and control the motor of the corresponding chain hoist 3 to perform precise forward and reverse rotation and start and stop, so as to adjust the chain extension and retraction length, thereby maintaining the stability, level and preset tension of the working platform unit 2. Specifically, the threshold range inside the centralized controller is set with a reasonable hysteresis range, which avoids over-adjustment caused by a single threshold to a certain extent. By monitoring the platform level and chain tension in real time, the chain length is automatically adjusted to automatically maintain the platform level and force balance, prevent local overload or overturning, and thus adapt to tidal changes in all weather conditions.
[0047] In this embodiment, a tension sensor is installed on the chain hoist 3 to monitor the tension value of each hoist in real time and convert the tension data into an electrical signal. A level sensor is installed at a suitable position in the working platform unit 2 to monitor the overall levelness of the platform unit in real time and convert the posture data into an electrical signal. The signal output terminals of all sensors continuously upload data through the system communication network. The central controller receives data from all tension and level sensors through the system communication network. The controller runs a preset control algorithm to compare and calculate the received real-time data (tension at each point, platform levelness) with preset ideal values (target tension, level reference). If the level sensor detects that one side of the platform is too high, the algorithm will determine that the hoist on that side needs to be tightened or the hoist on the other side needs to be loosened. After comparison and calculation, the central controller generates specific motor control commands for each chain hoist 3. The generated control commands are sent to the corresponding distributed servo control module (one for each electric hoist) through the system communication network. The distributed module receives the commands from the bus and drives the drive motor of its corresponding chain hoist 3 to perform precise forward rotation, reverse rotation, stop, and speed control. By controlling the motor's operation, the chain is precisely extended and retracted, thus changing its length. This embodiment requires no manual intervention and can automatically raise and lower according to tidal changes, keeping the entire work platform level and ensuring its stability and safety.
[0048] The implementation principle of this embodiment of a water-based photovoltaic installation on tidal flats is as follows: During the basic construction phase, according to the photovoltaic array layout, pipe piles 1 are precisely driven into the deep bearing layer in a rectangular grid pattern on the tidal flat to form a rigid support network. At the same time, installation interfaces are reserved at the top of the pipe piles 1 for subsequent connection of adjustment components.
[0049] During the platform prefabrication and transportation phase, the I-beams, steel fences 203, and railings 204 are prefabricated into standard working platform units 2 on shore or at a temporary site. The floats 205 are fixed to the bottom of the platform with clamps 206 and bolts, and the platform is towed to the target area by a small boat using its own buoyancy.
[0050] During the platform installation and connection phase, the platform unit is hoisted by a vessel and positioned above the corresponding pipe pile 1. The snap-fit component of the adjustment assembly is snapped into the top of the pipe pile 1. The snap-fit component is attached to the upper and lower ends of the chain hoist 3 and the platform frame, respectively. Adjacent platform units are spliced horizontally / vertically with bolts to form a continuous working surface, and a safety net 5 is installed.
[0051] During the platform leveling and operation phases, both manual and automatic control modes are used. In manual mode, construction personnel observe the platform's status and manually start and stop the electric chain hoist 3 to adjust the height of each corner, ensuring the platform is at a suitable working height, close to the beach surface during low tide and floating to avoid water during high tide.
[0052] In automatic control mode, a level sensor collects platform tilt data in real time, while a tension sensor monitors the balance of force on each chain. The data is uploaded to a centralized controller via a communication network. The controller compares the measured values with preset thresholds; if the deviation exceeds the limit, a control command is generated. The distributed servo module receives the command and drives the corresponding chain hoist motor in both forward and reverse directions, precisely raising and lowering the chain. The platform automatically returns to level, and the tension of each chain remains within a safe range. The entire process requires no manual intervention and can respond to tidal changes 24 hours a day.
[0053] During the construction and operation and maintenance phases, photovoltaic brackets, modules and other materials can be efficiently installed on a stable platform. The platform can be moved as a whole or adjusted locally as the project progresses. After construction is completed, the platform can be disassembled and recycled for reuse in other projects.
[0054] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
