Description

[0002] Pile foundation is an indispensable part of the load-bearing of high-pile docks, which transmits the load to the soil layer with good bearing capacity deep underground. The temperature in northern docks is low in winter, and some high-latitude ports are even frozen. Concrete structures such as pile foundations are easily damaged during freeze-thaw cycles. In winter, water freezes and expands in volume, and melts in spring and summer, resulting in increased pores, loose concrete and microcracks. Year-round freeze-thaw cycles cause significant damage, and freeze-thaw damage to pile foundations below the waterline is often more obvious. In addition, biological corrosion also has a great impact on the durability of pile foundations, because the underwater part of the pipe pile is more susceptible to the influence of water flow and nutrients, providing a good living environment, so shellfish, barnacles and microorganisms attach to it, reducing the durability of marine engineering structures.

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Example 1

[0021] like Figure 1 , Figure 4 The present embodiment provides a pile foundation antifreeze and anticorrosion device, comprising a berthing member 1 for ship collision prevention installed on a pipe pile 5 and a constant temperature module 6 for preventing the pipe pile 5 from freezing, wherein the constant temperature module 6 is installed in a splash zone and an ice zone on the pipe pile 5, and the berthing member 1 is installed at the edge of the dock; The pipe pile 5 is also provided with a power generation module and a battery 14, which converts the kinetic energy of the mooring member 1 when it is hit into electrical energy, and the electrical energy is stored in the battery 14, and the battery 14 provides electrical energy to the constant temperature module 6; The pipe pile 5 is also provided with a water spray module for removing pollutants on the outer wall of the pipe pile 5; The mooring structure 1 includes a fender 2, and the power generation module includes a piston 17 and a piston cylinder, and the piston cylinder is connected to the water spray module; When the fender 2 is hit, 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, the seawater in the piston cylinder is ejected outward.

[0022] This embodiment forms efficient utilization of kinetic energy during ship collision through the berthing component 1, the power generation module and the constant temperature module 6, which is energy-saving and environmentally friendly. The power generation module arranged inside the pipe pile 5 uses the inner wall of the pipe pile 5 to form a piston cylinder, and a piston 17 is arranged inside. The movement of the piston 17 can also squeeze and discharge the seawater entering the piston cylinder and spray it out in the form of a jet, so as to clean the pollutants attached to the outer wall of the pipe pile 5, avoid the pollutants attached to the pipe pile 5 and cause corrosion to the pipe pile 5, and improve the durability of the pipe pile 5. Example 2

[0023] This embodiment provides a pile foundation antifreeze and anticorrosion device based on Embodiment 1, except that: like Figure 1 As shown, the berthing structure 1 also includes an air pipe 3 and a one-way air inlet valve 4. A plurality of fenders 2 are provided to be able to cope with the impact of the ship when docking. The fenders 2 are arranged horizontally and parallelly at the edge of the dock. The fenders 2 are connected to each other through the air pipe 3, and the other end of the air pipe 3 passes through the pipe pile 5 under the dock.

[0024] like Figure 2 , Figure 3 As shown, the fender 2 is a hollow structure with an air chamber 201 inside. The fender 2 is made of rubber material and has a good rebound effect. The fender 2 is a long structure with a D-shaped cross-section. An air pipe 3 and a one-way air inlet valve 4 are arranged on one side end face. The air pipe 3 is connected with the air chamber 201, and the one-way air inlet valve 4 is connected with 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, ensuring that after the fender 2 is compressed during collision, the gas in the fender 2 enters the air pipe 3 as the kinetic energy for starting the power generation module.

[0025] like Figure 4 , Figure 6 , Figure 7 , Figure 8As shown, the power generation module also includes a top plate 15, a bottom plate 16 and a magnet 8. The top plate 15 and the bottom plate 16 are arranged above and below the pipe pile 5, respectively. The top plate 15, the bottom plate 16 and the inner wall of the pipe pile 5 form a piston cylinder, a piston 17 is arranged in the piston cylinder, a coil 9 is arranged in the piston 17, two magnets 8 of different polarities are respectively installed on both sides of the piston cylinder, and horizontal magnetic flux lines are formed in the piston cylinder. The coil 9 in the piston 17 is connected to the battery 14, and the battery 14 passes current into the coil 9. During the up and down movement of the piston 17, the coil 9 cuts the magnetic flux lines, thereby generating an induced current, and the induced current is stored in the battery 14.

[0026] 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 installation stability of the top plate 15 and the bottom plate 16 . The battery 14 is installed on the top plate 15 .

[0027] The 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 in the air chamber 24 is gas. The air chamber 24 is connected to the fender 2 through an air pipe 3. The air pipe 3 extends from a bottom hole 18 on the bottom plate 16 into the air chamber 24. The gas in the air chamber 24 is discharged into the air chamber 24 when the fender 2 is impacted and compressed. The gas in the air pipe 3 is input into the air chamber 24, thereby driving the piston 17 to move upward, thereby cutting the magnetic flux lines to generate an induced current.

[0028] A water pipe 13 is arranged at the outer wall position corresponding to the top plate 15 of the pipe pile 5. The water pipe 13 is annularly sleeved on the outer wall of the pipe pile 5. The water pipe 13 is connected to the water tank 23 through an opening 19. The opening 19 penetrates the upper pad and the wall of the pipe pile 5 and is connected to the water pipe 13. A plurality of one-way nozzles 7 are evenly arranged on the lower surface of the water pipe 13. Seawater can only be discharged from the water pipe 13 after passing through the one-way nozzles 7, and cannot enter the water pipe 13. The water in the water tank 23 is squeezed into the water 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 pipe 13 clean the outer wall of the pipe pile 5 below the water pipe 13. The water pipe 13 is located at a high position in the wave splash zone on the pipe pile 5, and organisms in the seawater attach to the pipe pile 5 below the water pipe 13.

[0029] A strip protrusion 25 is provided on the pipe pile 5, and a water inlet channel 27 is provided in the strip protrusion 25. One end of the water inlet channel 27 extends into the sea, and the other end is connected to the water pipe 13. After the fender 2 is hit and compressed, the outside enters through the one-way air inlet valve 4 provided on the side, and no gas is supplied to the air chamber 24. The piston 17 moves downward due to gravity and atmospheric pressure. Due to the atmospheric pressure, seawater enters the water pipe 13 from the water inlet channel 27 in the upper water chamber 23, and then enters the water chamber 23 through the opening 19, which serves as the reserve water for the next external water spraying to remove pollutants. After the fender 2 is hit, the fender 2 is compressed. Due to the atmospheric pressure, the outside air enters the air chamber 201 of the fender 2 from the one-way air inlet valve 4. During the downward movement of the piston 17, the gas in the air chamber 24 is discharged from the air pipe 3 into the air chamber 201 of the fender 2, increasing the air pressure in the air chamber 201. Under the action of atmospheric pressure and rubber elastic force, the fender 2 deformed by the ship's impact is restored to its original state.

[0030] like Figure 5 The constant temperature module 6 includes several layers of tinfoil films 10 covering the splash zone and the ice zone, each layer of tinfoil film 10 includes two layers of tinfoil, and PCT heating sheets 12 connected by wires 11 are evenly arranged between the two layers of tinfoil, and the wires 11 are connected to the battery 14. The tinfoil film 10 is installed on the outer wall of the pipe pile 5 through the film pressing plate 26 and the strip protrusions on the pipe pile 5. The length of the tinfoil film 10 is greater than the length of the film pressing plate 26, which is convenient for the tinfoil film 10 to be torn off from the pipe pile 5. The edges of the film pressing plate 26 on both sides are pressed tightly on the wall of the pipe pile 5 to ensure that the tinfoil film 10 is attached to the pipe pile 5 without gaps to prevent microorganisms from entering. The heated tinfoil film 10 heats the seawater near the pipe pile 5 to prevent the pipe pile 5 from freezing and thawing cycles, thereby improving the durability of the pipe pile 5. Each layer of tinfoil film 10 is independently set. After the outermost layer of tinfoil film 10 is not effective, the outermost layer of tinfoil film 10 is torn off and continued to be used.

[0031] The specific steps for installing the tinfoil film 10 are as follows: one end of the tinfoil layer with the PCT heating sheet 12 is clamped on the strip protrusion 25, and then the tinfoil 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 layers of tinfoil layers, use a film pressing plate 26 to install it on the strip protrusion 25, and press the edges of both ends of the tinfoil film 10 tightly against the wall of the pipe pile 5.

[0032] For the pipe pile 5 without the pile cap installed, the size of the pipe pile 5 can be determined first, and then the tinfoil film 10 is arranged in a circle according to the size, and the edge of the tinfoil film 10 is pressed tightly by the strip protrusion 25 and the film pressing plate 26, and then directly put on the pipe pile 5 for use. Then the water pipe 13 is installed on the strip protrusion 25. Example 3

[0033] This embodiment provides a method for using a pile foundation antifreeze and anticorrosion device based on Embodiment 1 or Embodiment 2, comprising the following steps: The ship docks towards the dock and hits the fender 2 on the berthing structure 1 on the edge of the dock. The fender 2 is compressed, and the gas in the fender 2 is transported to the piston 17 of the power generation module, driving the piston 17 to move; The piston 17 in the power generation module moves to convert the kinetic energy of the gas into electrical energy, which is stored in the battery 14; The constant temperature module 6 disposed on the pipe pile 5 generates heat through the power supply of the battery 14; When the piston 17 in the kinetic energy driven power generation module moves, the water spray module disposed on the pipe pile 5 sprays seawater from the piston cylinder to remove pollutants attached to the pipe pile 5 .

[0034] In step A, after the ship hits the fender 2 at the edge of the dock, the internal space of the fender 2 is compressed, and 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 flux lines generated by the electromagnetic induction in the piston cylinder, thereby generating an induced current. The magnitude of the induced electromotive force generated is E=BLV, where B is the magnetic induction intensity generated by the magnet 8, L is the effective length of the coil 9 cutting the magnetic flux lines, and V is the speed of the coil 9 cutting the magnetic flux lines. Thus, the power generation function is realized, and the generated electrical energy is stored in the battery 14 for use by the constant temperature module 6.

[0035] In step C, the constant temperature module 6 is powered on and heated through the PCT heating sheet 12 inside the tin foil layer, and then the heat is transferred through the tin foil to prevent the pipe pile 5 from being frozen.

[0036] 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, and the water enters the water pipe 13 from the opening 19, and then is sprayed out from the one-way nozzle 7. The sprayed water exerts an impact force on the pollutants on the wall of the pipe pile 5, thereby removing the pollutants on the wall of the pipe pile 5 and avoiding corrosion of the pipe pile 5.
