Abstract
Description
Technical Field
[0001] This invention relates to the field of pole and tower foundation protection technology, specifically to a replaceable pole and tower concrete pile foundation protection device. Background Technology
[0002] Concrete pile foundations for power poles are key components used to support various power pole facilities (such as power poles, communication towers, wind power towers, etc.). The function of the pile foundation is to effectively transfer the loads borne by the power pole (such as wind loads, gravity loads, impact loads, etc.) to the foundation, ensuring the stability and safety of the power pole structure.
[0003] The geological conditions of water bodies such as riverbeds, seabeds, lakes, and swamps are often complex, with potentially loose soil or uneven settlement. These conditions can easily lead to unstable tower foundations, causing towers to tilt or collapse. Furthermore, towers near water are constantly subjected to erosion by water flow, especially during flood season when the increased flow velocity and erosion force can easily hollow out or damage the tower foundation, affecting its stability. Aquatic environments typically have high humidity and salinity, causing corrosion of the tower and its foundation materials, reducing their strength and durability. In addition, civil engineering activities such as sand dredging and soil piling can also damage the tower foundation, increasing the risk of tower collapse. Maintenance departments generally implement anti-corrosion measures for towers and their foundation materials in complex geological conditions such as riverbeds and seabeds, such as applying anti-corrosion paint and using corrosion-resistant materials, to extend their service life and reduce the risk of collapse due to corrosion. During flood season or extreme weather conditions, inspections and monitoring of towers in water bodies should be strengthened. If any signs of tilting or collapse are found on the tower, emergency measures should be taken immediately, such as reinforcing the foundation and adjusting the guy wires, to ensure the stability and safety of the tower.
[0004] Concrete pile foundations for power poles located near water bodies are primarily used to support various facilities situated near rivers, lakes, and seabeds, such as power poles, communication towers, and offshore wind turbines. These foundations need to operate stably over long periods in complex aquatic environments; therefore, the impact of external factors such as water flow, wind, and corrosion must be carefully considered during design and construction. Compared to conventional concrete pile foundations, the requirements for pile foundations in aquatic environments are far more stringent. The foundations must not only withstand loads from the tower itself but also resist the influence of multiple external factors, including water flow, geological subsidence, and soil loosening.
[0005] Therefore, designing a new type of protective device for concrete pile foundations of power poles can effectively reduce the risk of power poles collapsing in water bodies such as riverbeds and seabeds, and improve the risk resistance and emergency repair capabilities of power poles in extreme weather conditions. This device has good practical application and market promotion value. Summary of the Invention

[0029] This invention provides a solid and stable support by pre-embedding the tower pile foundation in underwater silt and filling it with a crushed stone cushion layer, significantly enhancing the tower pile foundation's erosion resistance and long-term stability. The crushed stone cushion layer, through the interlocking effect between particles, effectively disperses the load from the tower body, preventing uneven settlement or tilting caused by concentrated loads. It also reduces the erosion effect of water flow on the pile foundation, preventing soil loss around the pile foundation and ensuring the bearing capacity and stability of the tower pile foundation. By installing a protective plate that rotates under the action of water flow, this invention effectively absorbs and disperses the impact force of the water flow, reducing the direct erosion of the tower pile foundation and significantly lowering the risk of pile foundation damage caused by seawater, river water, and lake currents. The protective plate can automatically rotate according to the intensity and direction of the water flow, and in conjunction with the anchoring effect of the plug-in rod, effectively stabilizes the crushed stone cushion layer, preventing its loss and further enhancing the stability and erosion resistance of the pile foundation. Furthermore, the design of the cleaning rod allows for the regular removal of deposits from the outer wall of the tower pile foundation, preventing deposit accumulation that could obstruct water flow or cause uneven scouring, and preventing reduced pile foundation lifespan due to biological corrosion. Through the effective sliding and scraping action of the cleaning rod, the corrosive effect of attached substances on the pile foundation is reduced, keeping the outer wall of the pile foundation clean and ensuring smooth water flow.
[0030] In summary, this invention effectively prevents the impact of seabed erosion on pile foundations. Especially under the influence of waves and tides, pile foundations are prone to uneven erosion, leading to settlement or instability. It can withstand complex water flow and tidal changes in marine environments, ensuring the long-term stable operation of tower pile foundations. Attached Figure Description

[0054] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0055] refer to Figures 1-15 A replaceable protective device for concrete pile foundations of towers, comprising:
[0056] The tower pile foundation is 100mm and is pre-embedded in the silt at the bottom of the water.
[0057] The foundation pit 101 is located on the silt at the bottom of the water. The depth of the foundation pit 101 reaches the middle position of the base of the tower pile foundation 100. The foundation pit 101 is filled with crushed stone to form a crushed stone cushion layer 102.
[0058] Multiple mounting plates 103 are provided on the tower pile foundation 100;
[0059] The protective plate 104 is rotatably mounted on the mounting plate 103;
[0060] Multiple plug-in rods 105 provided on the mounting plate 103 are used to be plugged into the crushed stone cushion layer 102 to increase the stability of the crushed stone cushion layer 102;
[0061] A plurality of clearing rods 106 are provided on one side of the mounting plate 103, and the clearing rods 106 slide around the outer wall of the tower pile foundation 100;
[0062] An anti-erosion component disposed between the protective plate 104 and the mounting plate 103 is used to move the position of the cleaning rod 106 when the protective plate 104 rotates.
[0063] During the process of the end of the protective plate 104 rotating from point a to point b, one of the plug rods 105 is inserted into the gravel pad 102; during the process of the end of the protective plate 104 rotating from point a to point c, two of the plug rods 105 are inserted into the gravel pad 102.
[0064] During the process of the end of the protective plate 104 rotating from point a to point b, the clearing rod 106 moves around the tower pile foundation 100. During the process of the end of the protective plate 104 rotating from point a to point c, the clearing rod 106 moves around the tower pile foundation 100. During the process of the end of the protective plate 104 rotating from point b to point a, the clearing rod 106 does not rotate. During the process of the end of the protective plate 104 rotating from point c to point a, the clearing rod 106 does not rotate.
[0065] When any one of the multiple protective plates 104 rotates, it will provide a preset rotational force to the other protective plates 104.
[0066] By setting up the tower pile foundation 100, during installation, the tower pile foundation 100 is pre-embedded in the underwater silt, and a foundation pit 101 is opened in the underwater silt. The foundation pit 101 is filled with crushed stone to form a crushed stone cushion layer 102, thereby providing a solid and stable support for the tower pile foundation 100. This crushed stone cushion layer 102 not only effectively disperses the load from the tower body, but also has several important functions. Through the interlocking effect between its particles, the crushed stone cushion layer 102 effectively improves the stability of the pile foundation, disperses external loads, and evenly distributes the pressure on the pile foundation, avoiding uneven settlement or tilting caused by concentrated loads, thus ensuring the long-term stability of the tower pile foundation 100. At the same time, it reduces the scouring effect of water flow on the pile foundation, preventing excessive removal of the soil around the tower pile foundation 100 by seabed erosion, which would affect the bearing capacity of the pile foundation. Mounting plates 103 can be installed onto the tower pile foundation 100 using bolts or fasteners. Multiple mounting plates 103 surround the tower pile foundation 100. When seabed currents are about to scour the tower pile foundation 100, protective plates 104 on the mounting plates 103 provide protection, absorbing the impact of the water flow. The design of the protective plates 104 effectively absorbs and disperses the impact force from the water flow, reducing the water pressure directly acting on the tower pile foundation 100, thereby effectively preventing damage to the pile foundation from seabed scour. The protective plates 104 can rotate according to the intensity and direction of the water flow. When the water flow impacts the area between the end of the protective plate 104 and the top of the mounting plate 103 (within a certain range), the water flow will be able to rotate. Figure 1In the example of the leftmost protective plate 104, the protective plate 104 rotates, and its end rotates from point a to point b (counterclockwise). During this process, one of the multiple insertion rods 105 moves downward, and its end can be inserted into the gravel cushion layer 102. The specific insertion depth is adapted to the intensity of the water flow impact. As the water flow impact increases, the insertion depth of the insertion rod 105 will gradually increase, stabilizing the gravel cushion layer 102 to a certain extent. During the water flow impact, the end of the insertion rod 105 is inserted into the gravel cushion layer 102. Through the gradually increasing insertion depth, the gravel particles can be tightly locked, reducing the displacement and loosening of the gravel cushion layer 102. At this time, the insertion rod 105 plays a role similar to "anchoring", stabilizing the structure of the gravel layer, thereby preventing excessive gravel from being carried away by seawater erosion, and avoiding the loss of the gravel layer leading to pile foundation exposure or instability. When the water flow impacts the area between the end of the protective plate 104 and the bottom silt (as shown in the example), Figure 1 (Example: the leftmost protective plate 104) Protective plate 104 rotates, its end rotating from point a towards point c (clockwise). Because seawater flows along the bottom silt, directly impacting the back of the mounting plate 103 and the protective plate 104, this water flow generates rotational kinetic energy in the protective plate 104. During this process, the rotation of the protective plate 104 helps disperse the impact force of the water flow, and the mounting plate 103 reduces the direct impact of the water flow on the pile foundation structure, thereby reducing the uneven stress on the pile foundation and the risk of excessive scouring. When the protective plate 104 rotates, two of the multiple insertion rods 105 move downwards, their ends inserting into the crushed stone cushion layer 102. In this way, the ends of the two insertion rods 105 penetrate deep into the crushed stone layer, increasing the number of insertion rods 105 and enhancing the anchoring effect. When water flows over the pile foundation from above the bottom silt, only one connector 105 is inserted into the gravel cushion layer 102. This reduces the resistance to the rotation of the protective plate 104, allowing it to respond more easily to changes in the water flow and rotate smoothly, further dispersing the impact force of the water flow. When water flows along the bottom silt over the pile foundation, two connectors 105 are inserted into the gravel cushion layer 102. While sacrificing some of the rotational flexibility of the protective plate 104, this design increases the stability and erosion resistance of the gravel layer. When water flows over the pile foundation from above the bottom silt, the insertion of two connectors 105 helps to further reinforce the gravel cushion layer 102, preventing the gravel from being carried away by the water flow and maintaining the stability of the pile foundation. Although this slightly increases the resistance during the rotation of the protective plate 104, by increasing the number of connecting rods 105, the crushed stone cushion layer 102 can be more effectively fixed, and the buoyancy resistance and scour resistance of the pile foundation can be improved. Especially under strong water flow conditions, this design ensures that the crushed stone layer maintains its stability under different water flow conditions. In addition, during the process of the end of the protective plate 104 rotating from point a to point b (with... Figure 1Taking the leftmost protective plate 104 as an example, the cleaning rod 106 can move around the tower pile foundation 100. By moving the cleaning rod 106, debris or sediment on the outer wall of the pile foundation can be removed, keeping the outer wall of the pile foundation clean and preventing accumulated substances from causing poor water flow or uneven scouring. If the water flow is obstructed by sediment on the tower pile foundation 100, the scouring force in some areas may be insufficient due to poor water flow, while the scouring effect in other areas may be too strong, causing the pile foundation surface to be scour deeper in some places. This uneven scouring may lead to tilting or uneven settlement of the pile foundation, increasing the risk to the pile foundation structure. Furthermore, using the cleaning rod 106 to clean the outer wall of the tower pile foundation 100 can effectively reduce the occurrence of biological corrosion. In the marine environment, organisms in seawater (such as algae, shellfish, sponges, etc.) may attach to the outer wall of the tower pile foundation 100. Over time, the growth and reproduction of these organisms may cause corrosion of the pile foundation surface, and the attachments may aggravate the corrosion, even affecting the structural integrity of the pile foundation. This corrosion phenomenon is called biocorrosion, especially in environments near water and in humid conditions. Biocorrosion can severely impact pile foundations and reduce their service life. The cleaning rod 106, by sliding and scraping away deposits on the outer wall of the tower pile foundation 100, can periodically remove these biological communities and deposits, thereby reducing the risk of biocorrosion. When the water flow is strong, the scraping effect of the cleaning rod 106 is more significant, preventing deposit accumulation and ensuring that the outer wall of the tower pile foundation 100 remains smooth and clean. The effect of the cleaning rod 106 moving around the tower pile foundation 100 during the rotation of the end of the protective plate 104 from point a to point c is similar. Subsequently, when the impact of the water flow disappears, the protective plate 104 will undergo a reset rotation, preventing the cleaning rod 106 from moving. This design aims to avoid the problem of the cleaning rod 106 only moving back and forth within a small range due to the instability of the water flow, creating dead zones. Specifically, after the water flow impact disappears, the reset rotation of the protective plate 104 effectively fixes the cleaning rod 106 in a stable position. This design avoids the cleaning rod 106 repeatedly making localized, short-distance reciprocating movements when the water flow fluctuates or the flow velocity changes significantly, thus preventing dead zones in certain areas of the tower pile foundation 100 that cannot be cleaned. If the cleaning rod 106 continues to move back and forth within a small range, some attached substances or deposits may not be removed, leading to localized corrosion, deposit accumulation, and even affecting the stability of the pile foundation. Therefore, by ensuring that the cleaning rod 106 stops moving after the water flow impact disappears, the cleaning work can be ensured to be uniform and effective throughout the entire range, avoiding potential risks caused by the cleaning rod 106 being unable to reach certain locations. Furthermore, when any one of the protective plates 104 rotates due to the impact of the water flow, it will provide a preset rotational force to the other protective plates 104, thereby achieving a linkage effect between multiple protective plates 104.On the pile foundation where the protective plate 104 has already undergone a certain degree of rotation, a preset rotational force is applied. When the initial water flow impact force is weak and the rotation amplitude of the protective plate 104 is small, when the later rotating protective plate 104 receives a large impact water flow, part of the rotational force of the latter will be transmitted to the previously rotating protective plate 104. This not only allows the previously rotated protective plate 104 to continue rotating, causing the corresponding insertion rod 105 to continue moving downwards a certain distance, but also compensates for the insufficient downward movement of the insertion rod 105 to a certain extent. This can effectively increase the insertion depth when the water flow impact is weak, improve the anchoring force of the crushed stone cushion layer 102, and thus better stabilize the pile foundation. It also allows the cleaning rod 106 to continue sliding along the predetermined path, avoiding jamming or stagnation under changes in water flow impact, thereby ensuring that the cleaning rod 106 can continuously and effectively clean the outer wall of the tower pile foundation 100. Through the rotational linkage between the protective plates 104, the cleaning rod 106 can slide stably along the preset trajectory, ensuring uniform and comprehensive cleaning effect. Furthermore, the protective plate 104 is integrated onto the mounting plate 103, and the mounting plate 103 is fixed to the tower pile foundation 100 with fasteners, simplifying the installation process and making the maintenance and replacement of the device more convenient. This application provides solid and stable support by pre-embedding the tower pile foundation 100 in underwater silt and filling it with a gravel cushion layer 102. The device utilizes the rotation of the protective plate 104 to absorb and disperse the impact of water flow, reducing the direct scouring of the pile foundation. Simultaneously, the gravel cushion layer 102 is anchored by the plug-in rod 105, enhancing the stability and scouring resistance of the pile foundation. The design of the cleaning rod 106 effectively cleans the sediment on the outer wall of the tower pile foundation 100, preventing biological corrosion and ensuring unobstructed water flow. This effectively prevents the impact of seabed scouring on the pile foundation, especially under the action of waves and tides, where the pile foundation is easily subjected to uneven scouring, leading to settlement or instability. The technical solution of this application can ensure the long-term stability of the tower pile foundation 100 in the variable marine environment and avoid structural instability caused by water erosion.
[0067] As a further embodiment of the present invention, a bracket 200 is connected to the mounting plate 103, the mounting plate 103 is rotatably connected to the bracket 200, a spring a201 is connected between the mounting plate 103 and the bracket 200, a plurality of flushing ports 202 are respectively opened at the top and bottom of the mounting plate 103, a drain port 203 is respectively opened on both sides of the mounting plate 103, and a drain plate 204 extending into the drain port 203 is connected to the bottom of the mounting plate 103;
[0068] By incorporating spring a201, the mounting plate 103 is rotatably connected to the bracket 200, with spring a201 connecting the mounting plate 103 to the bracket 200, enabling adaptive adjustment of the mounting plate 103 under water flow impact. The design of spring a201 not only provides the mounting plate 103 with rebound force but also automatically adjusts its position when the water flow impact force changes, ensuring it remains in an effective scour protection state. Multiple scour ports 202 are provided at the top and bottom of the mounting plate 103. These ports guide the water flow in a specific direction when impacting the tower pile foundation 100, reducing direct scour of the pile foundation. By providing drainage ports 203 on both sides of the mounting plate 103, the water flow can be quickly guided to the drainage plate 204, further dispersing the water flow impact force, reducing the concentrated impact of the water flow, and effectively preventing excessive scour of the pile foundation. The diversion plate 204 guides the water flow to a safe area, preventing excessive direct impact of the water flow on the outer wall of the tower pile foundation 100, thereby reducing the potential threat of scouring to the pile foundation structure. Furthermore, when the water flows through these scouring ports 202, the flow direction and velocity exert a certain force on the protective plate 104, promoting its rotation and effectively allowing the insertion rod 105 to be inserted into the crushed stone cushion layer 102. As the water flow intensity changes, the end of the insertion rod 105 gradually penetrates deeper into the crushed stone cushion layer 102, enhancing the stability and scouring resistance of the crushed stone cushion layer 102 through the tight locking of the particles.
[0069] As a further embodiment of the present invention, the anti-erosion component includes a connecting groove 205 formed on one side of the mounting plate 103, and a plug rod 105 is slidably connected in the connecting groove 205. A connecting rod 206 is rotatably connected to one of the plug rods 105 located in the middle, and the other end of the connecting rod 206 is rotatably connected to one side of the protective plate 104.
[0070] By setting the connecting rod 206, when the protective plate 104 is subjected to the impact force of the water flow and its end rotates from point a to point b (counterclockwise), the protective plate 104 will press down on a plug rod 105 located in the middle position through the connecting rod 206, allowing the plug rod 105 to move downward, thereby effectively anchoring the crushed stone cushion layer 102 and enhancing the stability and scour resistance of the pile foundation.
[0071] As a further embodiment of the present invention, the anti-erosion component further includes a gear a207 rotatably connected in the connecting groove 205, racks a208 meshing with the gear a207 are respectively connected to both sides of the middle plug rod 105, and racks b209 meshing with the gear a207 are respectively connected to the two plug rods 105 on both sides.
[0072] By setting gear a207, when the protective plate 104 is subjected to the impact force of the water flow and its end rotates from point a to point c (clockwise rotation), the protective plate 104 pulls one of the middle plug rods 105 upward through the connecting rod 206. During this process, the other two plug rods 105 can be moved downward through rack a208, gear a207 and rack b209, and inserted into the crushed stone cushion layer 102. This design can effectively enhance the anchoring effect when the water flow is about to impact the tower pile foundation 100 along the surface of the bottom silt, further stabilize the crushed stone cushion layer 102, prevent the loss of crushed stone, and improve the scour resistance of the pile foundation.
[0073] As a further embodiment of the present invention, a rack c300 is slidably connected to one side of the mounting plate 103, and the clearing rod 106 is connected to the rack c300. The racks c300 on multiple mounting plates 103 can form a ring gear structure. A rack d301 is connected to one of the middle insertion rods 105. The mounting plate 103 is provided with a gear b302 that extends into the connecting groove 205 and meshes with the rack d301. A gear c303 that meshes with the rack c300 is provided on one side of the gear b302.
[0074] By setting rack d301, when the protective plate 104 rotates counterclockwise and moves downward through the connecting rod 206 to the middle plug rod 105, rack d301 moves downward accordingly. At this time, gear b302 rotates, causing gear c303 to rotate. Rack c300 can slide along the outer wall of the tower pile foundation 100, so that the cleaning rod 106 scrapes the outer wall of the tower pile foundation 100, effectively cleaning the deposits or debris attached to the outer wall of the pile foundation.
[0075] As a further embodiment of the present invention, a frame 304 is connected to one side of the mounting plate 103, a connecting shaft a305 is connected to the frame 304, a connecting shaft b306 is rotatably connected inside the connecting shaft a305, a gear b302 is disposed on the connecting shaft b306, a lead screw 307 is provided on the connecting shaft b306, a threaded tube 308 is rotatably connected to the lead screw 307, the threaded tube 308 is slidably connected to the connecting shaft a305, a gear c303 is rotatably connected to the connecting shaft a305, a limiting block 309 is slidably connected to the connecting shaft a305, a limiting groove 310 adapted to the limiting block 309 is opened on the inner wall of the gear c303, a spring b311 is connected between the limiting block 309 and the connecting shaft a305, and a plurality of limiting protrusions 312 are connected to one side of the threaded tube 308;
[0076] By setting the connecting shaft b306, when the rack d301 moves downward and causes the gear b302 to rotate, the lead screw 307 can rotate. The rotation of the lead screw 307 can move the position of the threaded tube 308 through the force of the thread. The movement of the threaded tube 308 can push against the limiting block 309 and slide into the limiting groove 310 until the limiting block 309 is engaged in the limiting groove 310. When the gear b302 continues to rotate, it can contact the side wall of the limiting block 309 through the limiting protrusion 312 and drive the limiting block 309 to rotate, so that the gear c303 can rotate through the limiting block 309 and the limiting groove 310. The purpose of this setting is to allow the rack c300 to slide when one of the protective plates 104 is subjected to force and rotates, so that the rack c300 will not cause the other protective plates 104 to rotate when they are not subjected to the impact of the water flow. This avoids unnecessary rotation of other protective plates 104 that are not subjected to the impact of the water flow when there is no actual need. Furthermore, when the impact force of the subsequent water flow subsides, the protective plate 104 is reset by the force of the spring a201, and the connecting shaft b306 rotates in the opposite direction, allowing the threaded tube 308 to reset and move away from the limit block 309. At this time, the connecting shaft a305 can rotate freely in the gear c303, preventing the rack c300 from also resetting and sliding, thereby ensuring that the cleaning rod 106 can continuously and effectively clean the outer wall of the tower pile foundation 100.
[0077] As a further embodiment of the present invention, a connecting rod 400 is slidably connected to the frame 304, and a spring c401 is connected between the connecting rod 400 and the frame 304. A side opening 402 is provided on one of the middle insertion rods 105, and one end of the connecting rod 400 extends into the side opening 402. A limit frame 403 is connected to the bottom of the connecting rod 400. The gear b302 is slidably connected to the connecting shaft b306, and the gear b302 is rotatably connected to the limit frame 401. On the 3, a sleeve 404 is provided on one side of the gear c303. The sleeve 404 is rotatably connected to the frame 304. A traction shaft 405 is provided on the sleeve 404. A traction rope 406 is wound around the outer wall of the traction shaft 405. A traction frame 407 is slidably connected on the mounting plate 103. One end of the traction frame 407 extends into the side opening 402. Two limiting pieces 408 are connected in the side opening 402. There is a gap between the two limiting pieces 408 through the connecting rod 400.
[0078] By setting a connecting rod 400, the position of the connecting rod 400, controlled by the spring c401, allows the gear b302 to mesh with the rack d301. If the protective plate 104 rotates clockwise, the middle plug rod 105 moves upward, and can push the connecting rod 400 through the side opening 402, allowing the connecting rod 400 to slide along the connecting shaft b306 through the limiting frame 403 and leave the rack d301. At the same time, the traction frame 407 moves with the middle plug rod 105, limited by the limiting piece 408. The traction rope 406 can be used to rotate the sleeve 404 and the gear c303, which can also make the rack c300 slide. It is worth noting that instead of simply setting up a ratchet assembly between the connecting shaft b306 and the connecting shaft a305 to achieve unidirectional sliding of the gear c303, this application allows the cleaning rod 106 to slide along the outer wall of the tower pile foundation 100 only when the water flow impacts the protective plate 104. The purpose is to make full use of the impact force of the water flow to clean the outer wall of the tower pile foundation 100. A ratchet assembly is installed between connecting shaft b306 and connecting shaft a305 to replace components such as limiting block 309 and limiting groove 310. For example: when the middle connecting rod 105 moves downwards, it causes rack c300 to slide via gear b302, connecting shaft b306, ratchet assembly, connecting shaft a305, and gear c303. When the connecting rod 105 returns to its original position, connecting shaft b306 rotates freely within connecting shaft a305, without affecting the position of rack c300. When the middle connecting rod 105 moves upwards, gear b302 and connecting shaft b306 rotate freely within connecting shaft a305 due to the ratchet assembly. Without affecting the position of rack c300, when the protective plate 104 rotates to reset, gear b302, connecting shaft b306, ratchet assembly connecting shaft a305, and gear c303 allow rack c300 to slide. Although this arrangement can achieve unidirectional sliding of rack c300, rack c300 only slides during the reset rotation after the protective plate 104 rotates clockwise. That is, the sliding force of rack c300 comes from spring a201. If only the potential energy of spring a201 is used to drive the sliding of rack c300 and cleaning rod 106, it is insufficient to scrape away dirt from the outer wall of the tower pile foundation 100. Therefore, this application sets up multiple components such as the aforementioned connecting shaft a305, connecting shaft b306, limiting block 309, and traction rope 406 to fully utilize the impact force of water flow to clean the outer wall of the tower pile foundation 100.
[0079] As a further embodiment of the present invention, a connecting pipe 409 is connected to one side of the gear c303, a ratchet mechanism 410 is connected between the connecting pipe 409 and the sleeve 404, and a spring d411 is connected between the sleeve 404 and the frame 304.
[0080] By setting a ratchet mechanism 410, when the traction frame 407 moves upward, the traction rope 406 can pull the traction shaft 405 to rotate. The rotation of the traction shaft 405 and the sleeve 404 can cause the spring d411 to twist and generate potential energy. When the sleeve 404 rotates, it can cause the connecting pipe 409 and the gear c303 to rotate through the ratchet mechanism 410. At this time, the rack c300 slides. When the subsequent protective plate 104 is reset and rotated, the sleeve 404 is reset and rotated again by the potential energy of the spring d411 to rewind the traction rope 406. The ratchet mechanism 410 allows the sleeve 404 to rotate freely on the outer wall of the connecting pipe 409 without affecting the gear c303 and the rack c300. This avoids the problem that the rack c300 also resets and slides, and only slides back and forth in one area, which cannot completely remove the corrosion on the outer wall of the tower pile foundation 100. It is worth noting that the purpose of the ratchet mechanism 410 is to allow the sleeve 404 to rotate in a reset manner, without driving the rack c300 to slide when the plug rod 105 moves in a reset manner. The function of the ratchet mechanism 410 is to ensure that the sleeve 404 can automatically reset when the protective plate 104 resets, thereby retracting the traction rope 406 and restoring the sleeve 404 to its original position.
[0081] As a further embodiment of the present invention, the connecting shaft b306 includes a rotating shaft a500 rotatably connected to the connecting shaft a305, a rotating shaft b501 rotatably connected to the rotating shaft a500, a gear b302 slidably connected to the rotating shaft a500, a lead screw 307 connected to the rotating shaft b501, a damping rod 502 slidably connected to the connecting shaft a305, a spring e503 connected between the damping rod 502 and the connecting shaft a305, a damping groove 504 is formed on the inner wall of the connecting shaft b306, the damping groove 504 is a trapezoidal groove, and one end of the damping rod 502 is connected to a trapezoidal portion adapted to the damping groove 504;
[0082] By setting up a damping rod 502 and a damping groove 504, the damping rod 502 is subjected to the force of the spring e503 and cooperates with the damping groove 504. A certain frictional force can be formed between the trapezoidal part and the trapezoidal groove through the force of the spring e503. The greater the potential energy of the spring e503, the stronger the frictional force will be. When the gear b302 and the shaft a500 rotate, the shaft b501 can be rotated through this frictional force, which is enough to make the gear c303 and the cleaning rod 106 slide. The cleaning rod 106 is used to clean the outer wall of the tower pile foundation 100. In actual protection operations, when one protective plate 104 rotates, and the other protective plates 104 also rotate due to the impact of the water flow, because the previous protective plate 104 has already rotated, causing the limiting rod to insert into the limiting groove 310, the subsequently rotating protective plate 104 will also cause its corresponding limiting rod to insert into the limiting groove 310, which will cause a conflict. Therefore, components such as rotating shaft a500, rotating shaft b501, damping rod 502, damping groove 504, and spring e503 are provided. A single protective plate 104 can also cause the rack c300 to slide. During this process, if the previously rotating protective plate 104 has not yet rotated to its limit position, the protective plate 104 will rotate a certain angle, allowing the insertion rod 105 to penetrate deeper into the gravel pad 102 for stronger anchoring, until the friction between the damping rod 502 and the damping groove 504 is overcome. If the previously rotating protective plate 104 has already rotated to its limit position, the impact force of the water flow will be greater than the friction between the damping rods 502 and 502, thus overcoming the friction and causing rotation. It is worth noting that whether the damping groove 504 and damping rod 502 corresponding to the previously rotated protective plate 104 disengage, or the damping groove 504 and damping rod 502 corresponding to the subsequently rotated protective plate 104 disengage, it will not affect the overall protective effect. Regardless of whether the impact force of the water flow is light or heavy, it will provide the rack c300 with a sliding force, providing cleaning capability for the cleaning rod 106 and effectively avoiding interference between multiple protective plates 104.
[0083] As a further embodiment of the present invention, a magnetic strip 505 is connected to the inner wall of the rotating shaft b501, which magnetically attracts the trapezoidal portion of the damping rod 502.
[0084] By incorporating a magnetic stripe 505, the friction is further enhanced. The magnetic attraction can increase the friction between the damping rod 502 and the damping groove 504 to a certain extent, allowing the rack c300 to fully follow the movement of the protective plate 104.
[0085] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
