Description

Technical Field

[0001] This invention relates to the field of antifreeze and anticorrosion of wharf pile foundations, and in particular to a pile foundation antifreeze and anticorrosion device and its usage method. Background Technology

[0002] Piles are an essential load-bearing component of high-pile wharves, transferring the load to deeper, more resilient soil layers. In northern ports, winter temperatures are low, and some high-latitude ports even freeze over, making concrete structures like piles susceptible to damage during freeze-thaw cycles. In winter, water expands when it freezes, and thawing in spring and summer increases porosity, leading to loose concrete and microcracks. These repeated freeze-thaw cycles cause significant damage, often more pronounced in piles below the waterline. Furthermore, biological corrosion greatly impacts pile durability. The underwater portion of pipe piles is more susceptible to water flow and nutrients, providing a favorable environment for shellfish, barnacles, and microorganisms to attach, reducing the durability of marine structures.

[0003] Existing marine concrete methods typically employ high-performance concrete, concrete surface coatings, and the addition of admixtures to prevent freeze-thaw cycles, thereby extending the service life of marine structures. This undoubtedly increases the production cost and cycle time of pile foundations. While manual cleaning of pile foundation attachments is effective, it is inconvenient and untimely. Therefore, finding appropriate methods to improve the durability of pile foundations is crucial. Summary of the Invention

[0004] The purpose of this invention is to provide a pile foundation antifreeze and anticorrosion device and its usage method, which improves the antifreeze and anticorrosion properties of pipe piles, thereby improving the durability of pipe piles.

[0005] To solve the above technical problems, the following technical solution is adopted:

[0006] In a first aspect, the present invention provides a pile foundation antifreeze and anticorrosion device, comprising a berthing component for ship collision prevention installed on a pipe pile and a constant temperature module for preventing the pipe pile from freezing, wherein the constant temperature module is installed on the splash zone and icing zone of the pipe pile, and the berthing component is installed on the edge of the dock.

[0007] The pipe pile is also equipped with a power generation module and a battery, which converts the kinetic energy of the berthing component into electrical energy when it is impacted. The electrical energy is stored in the battery, and the battery provides electrical energy to the constant temperature module.

[0008] The pipe pile is also equipped with a water spray module for removing contaminants from the outer wall of the pipe pile;

[0009] The berthing component includes a fender, and the power generation module includes a piston and a piston cylinder, with the piston cylinder connected to the water jet module;

[0010] When the fender is impacted, it is compressed, and the gas inside the fender drives the piston to move, thereby generating electricity; during the piston's movement, seawater inside the piston cylinder is ejected outward.

[0011] The berthing component also includes an air supply pipe and a one-way air intake valve. The fender is provided with at least three of them. An air chamber is provided inside the fender. Each side of the fender is connected to an air supply pipe and a one-way air intake valve. The air chamber is connected to the air supply pipe. Gas can only enter the air chamber from the outside through the one-way air intake valve and cannot flow from the air chamber to the outside. The other end of the air supply pipe is connected to the power generation module.

[0012] The power generation module also includes a base plate, a top plate, magnets, and coils. The inner cavity of the pipe pile is provided with the base plate and the top plate, with the top plate located directly above the base plate. The top plate, the base plate, and the inner wall of the pipe pile form the piston cylinder. Magnets of different polarities are provided on both sides of the piston cylinder. The piston is disposed inside the piston cylinder. The coils are arranged inside the piston to satisfy the principle that the piston cuts the magnetic field lines generated by the magnets when it moves. The coils are connected to the battery, and the induced current generated in the coils is stored in the battery.

[0013] The piston divides the piston cylinder into a water chamber and an air chamber, with the water chamber located above the air chamber;

[0014] The bottom plate has a bottom hole in the middle, which is connected to the air supply pipe in the berthing component. The other end of the air supply pipe is connected to the fender in the berthing component. When the fender is hit by a ship, the internal space of the fender is compressed into the air chamber, thereby pushing the piston to move upward.

[0015] Optionally, the constant temperature module includes several layers of tin foil film covering the splash zone and the icing zone. The tin foil film includes two layers of tin foil and a heating element disposed between the two layers of tin foil. The heating element is connected to the battery through a wire.

[0016] Optionally, the tin foil film is installed on the pipe pile by cooperating with the strip-shaped protrusion on the pipe pile through a pressing plate, and the tin foil film is located between the pressing plate and the strip-shaped protrusion.

[0017] Optionally, the length of the foil film is greater than the length of the pressure plate.

[0018] Optionally, an upper pad is provided between the top plate and the inner wall of the pipe pile, and a lower pad is provided between the bottom plate and the inner wall of the pipe pile, and the battery is installed on the top plate.

[0019] Optionally, the water spraying module includes a water supply pipe and a water inlet channel. The water supply pipe is installed on the outer wall of the pipe pile. The water supply pipe is connected to the air chamber through an opening. The bottom of the water supply pipe is provided with several one-way nozzles. When the fluid passes through the one-way nozzles, it can only be discharged from the water supply pipe. External fluid cannot enter the water supply pipe from the one-way nozzles.

[0020] The water inlet channel is located inside the strip-shaped protrusion of the pipe pile. The top end of the water inlet channel is connected to the water conveyance pipeline, and the other end is located in seawater.

[0021] The water supply pipe on the outer wall of the pipe pile is at the same height as the top plate inside the pipe pile.

[0022] In a second aspect, the present invention provides a method of using a pile foundation antifreeze and anticorrosion device, the device comprising the pile foundation antifreeze and anticorrosion device as described in any one of the first aspects, comprising the following steps:

[0023] A. The ship docks towards the pier and impacts the fender on the berthing structure at the edge of the pier. The fender is compressed, and the gas inside the fender is sent to the piston of the power generation module, driving the piston to move.

[0024] B. The piston movement within the power generation module converts the kinetic energy of the gas into electrical energy, which is then stored in the battery.

[0025] C. The constant temperature module installed on the pipe pile heats up through battery power;

[0026] D. When the piston in the kinetic energy driven power generation module moves, the water spray module installed on the pipe pile sprays seawater out from the piston cylinder to remove pollutants attached to the pipe pile.

[0027] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0028] 1. This invention converts the kinetic energy of the berthing mechanism from the impact of the ship into electrical energy by setting up a berthing mechanism and a power generation module, and stores it in a battery to power the constant temperature module. The constant temperature module can prevent the pipe pile from freezing and thawing, thus improving the durability of the pipe pile. A water spraying module is also provided on the pipe pile. During the process of converting kinetic energy into electrical energy, seawater in the piston cylinder is sprayed out to remove pollutants attached to the outer wall of the pipe pile and prevent the pipe pile from being corroded by pollutants.

[0029] 2. The fender of this invention is connected to the piston cylinder via an air supply pipe. When compressed, the gas inside the fender enters the piston cylinder through the air supply pipe, thereby driving the piston to move. The moving piston cuts the magnetic field lines generated by electromagnetic induction within the piston cylinder, thus generating electrical energy. The electrical energy is stored in a battery to power the heating element on the pipe pile. The heating effect of the heating element prevents the pipe pile from freezing, thereby reducing damage to the pipe pile.

[0030] 3. The seawater sprayed out by the water spray module of the present invention enters the piston cylinder from the water inlet channel through the atmospheric pressure when the piston returns to its original position, and is then compressed by the movement of the piston until it is sprayed out from the one-way nozzle. The one-way nozzle is set at the bottom of the water supply pipeline to spray the pipe pile at the sea level, making it easier to remove pollutants. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use.

[0042] Example 1

[0043] like Figure 1 , Figure 4 The present embodiment provides a pile foundation antifreeze and anticorrosion device, including a ship-baiting component 1 for ship collision prevention installed on the pipe pile 5 and a constant temperature module 6 for preventing the pipe pile 5 from freezing. The constant temperature module 6 is installed on the splash zone and icing zone of the pipe pile 5, and the ship-baiting component 1 is installed on the edge of the dock.

[0044] The pipe pile 5 is also equipped with a power generation module and a battery 14, which converts the kinetic energy of the berthing component 1 into electrical energy when it is impacted. The electrical energy is stored in the battery 14, and the battery 14 provides electrical energy to the constant temperature module 6.

[0045] The pipe pile 5 is also equipped with a water spray module for removing contaminants from the outer wall of the pipe pile 5;

[0046] The berthing component 1 includes a fender 2, and the power generation module includes a piston 17 and a piston cylinder, with the piston cylinder connected to the water jet module;

[0047] When the fender 2 is impacted, it is compressed, and the gas inside the fender 2 drives the piston 17 to move, thereby generating electricity; during the movement of the piston 17, seawater inside the piston cylinder is ejected outward.

[0048] This embodiment utilizes the hull-mounted component 1, the power generation module, and the constant temperature module 6 to efficiently utilize the kinetic energy during a ship collision, achieving energy conservation and environmental protection. The power generation module, installed inside the pipe pile 5, forms a piston cylinder on the inner wall of the pipe pile 5, and a piston 17 is installed inside. The movement of the piston 17 can also squeeze and discharge the seawater entering the piston cylinder, spraying it out in a jet form to clean the pollutants attached to the outer wall of the pipe pile 5, preventing pollutants from adhering to the pipe pile 5 and causing corrosion, thus improving the durability of the pipe pile 5.

[0049] Example 2

[0050] This embodiment provides a pile foundation antifreeze and anti-corrosion device based on Embodiment 1, with the following differences:

[0051] like Figure 1As shown, the berthing component 1 also includes an air supply pipe 3 and a one-way air intake valve 4. Several fenders 2 are provided to cope with the impact when the ship is berthed. The fenders 2 are arranged horizontally and parallel to each other at the edge of the dock. The fenders 2 are connected to each other through the air supply pipe 3. The other end of the air supply pipe 3 passes through the pipe pile 5 under the dock.

[0052] like Figure 2 , Figure 3 As shown, the fender 2 is a hollow structure with an internal air chamber 201. The fender 2 is made of rubber and has a good rebound effect. The fender 2 is a long body structure with a D-shaped cross-section. An air supply pipe 3 and a one-way air inlet valve 4 are provided on one end face. The air supply pipe 3 is connected to the air chamber 201, and the one-way air inlet valve 4 is connected to the air chamber 201. The gas can only enter the air chamber 201 from the outside through the one-way air inlet valve 4 and cannot flow from the air chamber 201 to the outside. This ensures that after the fender 2 is compressed during impact, the gas inside the fender 2 enters the air supply pipe 3 and serves as the kinetic energy for starting the power generation module.

[0053] like Figure 4 , Figure 6 , Figure 7 , Figure 8 As shown, the power generation module also includes a top plate 15, a bottom plate 16, and magnets 8. The top plate 15 and bottom plate 16 are respectively arranged above and below the pipe pile 5. The top plate 15, bottom plate 16, and inner wall of the pipe pile 5 form a piston cylinder. A piston 17 is installed inside the piston cylinder, and a coil 9 is installed inside the piston 17. Two magnets 8 of different polarities are respectively installed on both sides of the piston cylinder, forming transverse magnetic field lines inside the piston cylinder. The coil 9 inside the piston 17 is connected to a battery 14, and the battery 14 supplies current to the coil 9. During the up-and-down movement of the piston 17, the coil 9 cuts the magnetic field lines, thereby generating an induced current, which is stored in the battery 14.

[0054] An upper pad 21 is provided between the top plate 15 and the inner wall of the pipe pile 5, and a lower pad 22 is provided between the bottom plate 16 and the inner wall of the pipe pile 5 to increase the stability of the installation of the top plate 15 and the bottom plate 16. The battery 14 is installed on the top plate 15.

[0055] Piston 17 divides the piston cylinder into an air chamber 24 and a water chamber 23. The air chamber 24 is located below the water chamber 23. The medium inside the air chamber 24 is gas. The air chamber 24 is connected to the fender 2 through an air supply pipe 3. The air supply pipe 3 extends into the air chamber 24 from the bottom hole 18 on the bottom plate 16. The gas in the air chamber 24 is discharged into the air chamber 24 when the fender 2 is compressed by the impact. The gas is input into the air chamber 24 through the air supply pipe 3, thereby driving the piston 17 to move upward, thereby cutting the magnetic field lines and generating an induced current.

[0056] A water supply pipe 13 is installed on the outer wall of the pipe pile 5, corresponding to the top plate 15. The water supply pipe 13 is circular and fits around the outer wall of the pipe pile 5. The water supply pipe 13 is connected to the water tank 23 through an opening 19, which penetrates the upper pad and the wall of the pipe pile 5. Multiple one-way nozzles 7 are evenly arranged on the lower surface of the water supply pipe 13. Seawater passing through the one-way nozzles 7 can only be discharged from the water supply pipe 13 and cannot enter the water supply pipe 13. Water in the water tank 23 is forced into the water supply pipe 13 by the upward movement of the piston 17, and then sprayed out through the one-way nozzles 7. The one-way nozzles 7 located on the lower surface of the water supply pipe 13 clean the outer wall of the pipe pile 5 below the water supply pipe 13. The water supply pipe 13 is located at a high position in the splash zone of the pipe pile 5, and marine organisms in the seawater attach to the pipe pile 5 below the water supply pipe 13.

[0057] A strip-shaped protrusion 25 is provided on the pipe pile 5, and a water inlet channel 27 is provided inside the strip-shaped protrusion 25. One end of the water inlet channel 27 extends into the sea, and the other end is connected to the water supply pipe 13. After the fender 2 is impacted and compressed, the outside air enters through the one-way air inlet valve 4 on the side, and no longer supplies gas to the air chamber 24. The piston 17 moves downward due to gravity and atmospheric pressure. Due to atmospheric pressure, seawater enters the water supply pipe 13 from the water inlet channel 27 into the water chamber 23 above, and then enters the water chamber 23 through the opening 19, serving as backup water for the next spraying of water to remove pollutants. After the fender 2 is impacted and compressed, the outside air enters the air chamber 201 of the fender 2 through the one-way air inlet valve 4 due to atmospheric pressure. During the downward movement of the piston 17, the gas in the air chamber 24 is discharged into the air chamber 201 of the fender 2 from the air supply pipe 3, increasing the air pressure in the air chamber 201. Under the action of atmospheric pressure and the elastic force of the rubber, the fender 2, which has been deformed by the impact of the ship, is restored to its original shape.

[0058] like Figure 5 The constant temperature module 6 includes several layers of foil film 10 covering the splash zone and the icing zone. Each layer of foil film 10 includes two layers of foil, with a PCT heating element 12 connected by a wire 11 evenly arranged between the two layers of foil. The wire 11 is connected to the battery 14. The foil film 10 is installed on the outer wall of the pipe pile 5 through a pressing plate 26 that engages with the strip-shaped protrusions on the pipe pile 5. The length of the foil film 10 is greater than the length of the pressing plate 26, making it easy to peel off the foil film 10 from the pipe pile 5. Both sides of the pressing plate 26 are pressed tightly against the wall of the pipe pile 5 to ensure that the foil film 10 adheres to the pipe pile 5 without gaps, preventing microorganisms from entering. The heated foil film 10 heats the seawater near the pipe pile 5, preventing the pipe pile 5 from undergoing freeze-thaw cycles and improving the durability of the pipe pile 5. Each layer of foil film 10 is set independently. If the outermost foil film 10 is no longer effective, it can be peeled off and reused.

[0059] The specific installation steps of the foil film 10 are as follows: one end of the foil layer with PCT heating element 12 is clamped on the strip protrusion 25, and then the foil film 10 is wrapped around the outer wall of the pipe pile 5, and the other end is clamped on the strip protrusion 25. After installing multiple foil layers, the pressure plate 26 is installed on the strip protrusion 25 to press the edges of both ends of the foil film 10 tightly onto the wall of the pipe pile 5.

[0060] For pipe piles 5 without pile caps, the dimensions of pipe piles 5 can be determined first. Then, the tin foil film 10 is arranged in a circle according to the dimensions, and the edges of the tin foil film 10 are pressed tightly by the strip protrusions 25 and the pressure plate 26. Then, it is directly fitted onto the pipe pile 5. Then, the water supply pipe 13 is installed on the strip protrusions 25.

[0061] Example 3

[0062] This embodiment provides a method for using a pile foundation antifreeze and anti-corrosion device based on Embodiment 1 or Embodiment 2, including the following steps:

[0063] The ship docks towards the pier and impacts the fender 2 on the berthing component 1 at the edge of the pier. The fender 2 is compressed, and the gas inside the fender 2 is delivered to the piston 17 of the power generation module, driving the piston 17 to move.

[0064] The piston 17 inside the power generation module moves to convert the kinetic energy of the gas into electrical energy, which is then stored in the battery 14.

[0065] The constant temperature module 6 installed on the pipe pile 5 generates heat through the power supply of the battery 14;

[0066] When the piston 17 in the kinetic energy-driven power generation module moves, the water spray module installed on the pipe pile 5 sprays seawater out from the piston cylinder to remove pollutants attached to the pipe pile 5.

[0067] In step A, after the ship impacts the fender 2 at the edge of the dock, the internal space of the fender 2 is compressed. The internal gas enters the gas chamber 24 of the piston cylinder through the gas pipe 3. The gas pressure in the gas chamber 24 increases, pushing the piston 17 upward. The upward-moving piston 17 cuts the magnetic field lines generated by the electromagnetic field inside the piston cylinder, thereby generating an induced current. The magnitude of the induced electromotive force is E=BLV, where B is the magnetic induction intensity generated by the magnet 8, L is the effective length of the magnetic field lines cut by the coil 9, and V is the speed at which the coil 9 cuts the magnetic field lines. This achieves the power generation function, and the generated electrical energy is stored in the battery 14 to power the constant temperature module 6.

[0068] In step C, the constant temperature module 6 heats up by energizing the PCT heating element 12 inside the tin foil layer, and then the heat is transferred through the tin foil to prevent the pipe pile 5 from freezing.

[0069] In step D, seawater enters the water tank 23 of the piston cylinder through the water inlet channel 27 on the strip protrusion 25 on the pipe pile 5. When the piston 17 moves upward, it squeezes the water in the water tank 23. The water enters the water delivery pipe 13 through the opening 19 and then sprays out from the one-way nozzle 7. The sprayed water impacts the contaminants on the wall of the pipe pile 5, thereby removing the contaminants from the wall of the pipe pile 5 and preventing corrosion of the pipe pile 5.
