Description

Technical Field

[0001] The invention relates to the technical field of pole tower pile foundation protection, and in particular to a replaceable pole tower concrete pile foundation protection device. Background Art

[0002] The tower concrete pile foundation is a key component used to support various tower facilities (such as power towers, communication towers, wind power towers, etc.). The function of the tower pile foundation is to effectively transfer the loads borne by the tower (such as wind load, gravity load, impact load, etc.) to the foundation to ensure the stability and safety of the tower structure.

[0003] The geological conditions of waters such as riverbeds, seabeds, lakes, and swamps are often complex, and the soil may be relatively soft or have uneven settlement. Such geological conditions can easily lead to unstable foundations of pole towers, which in turn cause the pole towers to tilt or fall. In addition, the pole towers near the waters are often eroded by water flow. Especially in the flood season, the water flow speed is accelerated and the scouring force is enhanced, which can easily lead to the foundation of the pole tower being hollowed out or damaged, thus affecting the stability of the pole tower. The water environment usually has high humidity and salinity, which causes the pole tower and its foundation materials to be corroded, reducing their strength and durability. In addition, civil engineering activities such as sand excavation and earth piling may also damage the foundation of the pole tower and increase the risk of the pole tower falling. In view of complex geological conditions such as riverbeds and seabeds, the operation and maintenance department generally takes anti-corrosion measures for the pole tower and its foundation materials, such as painting anti-corrosion paint and using corrosion-resistant materials, to extend their service life and reduce the risk of falling due to corrosion. During the flood season or extreme weather conditions, inspections and monitoring of pole towers in waters should be strengthened. Once the pole tower shows signs of tilting or falling, emergency measures should be taken immediately, such as strengthening the foundation, adjusting the guy wires, etc., to ensure the stability and safety of the pole tower.

[0004] Concrete pile foundations for towers near waters are mainly used to support various facilities located near rivers, lakes, and seabed areas, such as power towers, communication towers, offshore wind power towers, etc. These pile foundations need to work stably for a long time in the complex environment of adjacent waters. Therefore, the impact of external factors such as water flow, wind force, and corrosion on the pile foundations needs to be specially considered during the design and construction process. Compared with conventional concrete pile foundations, the requirements for pile foundations in the environment near waters are more stringent. The pile foundation not only needs to bear the load from the tower body, but also needs to resist the impact of multiple external factors such as water flow, geological collapse, and loose soil.

[0005] Therefore, designing a new type of pole tower concrete pile foundation protection device can effectively reduce the risk of pole tower toppling in riverbeds, seabeds and other waters, and improve the pole tower's risk resistance and emergency repair capabilities in extreme climate environments. The device has good practical application and market promotion value. Summary of the invention

DETAILED DESCRIPTION

[0021] The following will be combined with the 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, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] refer to Figure 1-Figure 15 , a replaceable tower concrete pile foundation protection device, comprising: The tower pile foundation 100 is pre-buried in the bottom mud; A foundation pit 101 is provided on the bottom mud, the depth of the foundation pit 101 reaches the middle position of the base of the pole tower pile foundation 100, and the foundation pit 101 is filled with gravel to form a gravel cushion layer 102; A plurality of mounting plates 103 provided on the pole tower pile foundation 100; A protection plate 104 disposed on the mounting plate 103, rotatably disposed on the mounting plate 103; A plurality of plug-in rods 105 provided on the mounting plate 103 are used to be plugged into the gravel cushion layer 102 to increase the stability of the gravel cushion layer 102; A plurality of cleaning rods 106 are provided on one side of the mounting plate 103, and the cleaning rods 106 slide around the outer wall of the pole tower pile foundation 100; An anti-scouring component provided between the protection plate 104 and the mounting plate 103, used to move the position of the cleaning rod 106 when the protection plate 104 rotates; In the process of the end of the protective plate 104 rotating from point a to point b, one of the plug-in rods 105 is plugged into the gravel cushion layer 102, and in the process of the end of the protective plate 104 rotating from point a to point c, two of the plug-in rods 105 are plugged into the gravel cushion layer 102; In which, when the end of the protective plate 104 rotates from point a to point b, the cleaning rod 106 moves around the pole tower pile foundation 100; when the end of the protective plate 104 rotates from point a to point c, the cleaning rod 106 moves around the pole tower pile foundation 100; when the end of the protective plate 104 rotates from point b to point a, the cleaning rod 106 does not rotate; when the end of the protective plate 104 rotates from point c to point a, the cleaning rod 106 does not rotate; When any one of the plurality of protection plates 104 rotates, it will give a preset rotational force to other protection plates 104; By setting the pole tower pile foundation 100, during installation, the pole tower pile foundation 100 is pre-buried on the underwater mud, and a foundation pit 101 is opened on the underwater mud, and gravel is filled in the foundation pit 101 to form a gravel cushion layer 102, thereby providing a solid and stable support for the pole tower pile foundation 100. The gravel cushion layer 102 can not only effectively disperse the load from the tower body, but also has multiple important functions. The gravel cushion layer 102 effectively improves the stability of the pile foundation through the interlocking effect between its particles, can disperse the external load, and evenly distribute the pressure on the pile foundation, avoiding uneven settlement or tilting caused by load concentration, thereby ensuring the long-term stability of the pole tower pile foundation 100, and at the same time reducing the scouring effect of water flow on the pile foundation, avoiding the seabed scouring and taking away too much soil around the pole tower pile foundation 100, thereby affecting the bearing capacity of the pile foundation. The mounting plate 103 can be installed on the pole tower pile foundation 100 by means of bolts and fasteners. Multiple mounting plates 103 surround the pole tower pile foundation 100. When the seabed current is about to scour the pole tower pile foundation 100, the protective plate 104 on the mounting plate 103 plays a protective role and receives the impact of the water current. The design of the protective plate 104 can effectively absorb and disperse the impact force brought by the water current, reduce the water current pressure directly acting on the pole tower pile foundation 100, and thus effectively prevent the damage to the pile foundation caused by the seabed scouring. The protective plate 104 can rotate according to the strength and direction of the water current. When the water current hits the end of the protective plate 104 to the top of the mounting plate 103 (in Figure 1 In the example of the leftmost protective plate 104 in the figure), the protective plate 104 rotates, and its end rotates from point a toward point b (counterclockwise rotation). During this process, one of the multiple plug-in rods 105 set will move downward, and its end can be plugged into the gravel cushion layer 102. The specific insertion depth adapts to the intensity of the water flow impact. As the water flow impact increases, the insertion depth of the plug-in rod 105 will gradually deepen, stabilizing the gravel cushion layer 102 to a certain extent. During the water flow impact process, the end of the plug-in rod 105 is inserted into the gravel cushion layer 102. By gradually deepening the insertion depth, the gravel particles can be tightly locked, reducing the displacement and loosening of the gravel cushion layer 102. At this time, the plug-in rod 105 plays a role similar to "anchoring", stabilizing the structure of the gravel layer, thereby preventing excessive gravel from being carried away during seawater scouring, and avoiding the loss of the gravel layer that causes the pile foundation to be exposed or unstable. When the water flow impacts the area between the end of the protective plate 104 and the bottom mud (with Figure 1Taking the leftmost protective plate 104 as an example), the protective plate 104 rotates, and its end rotates from point a toward point c (clockwise). Since the seawater passes over the protective plate 104 along the bottom mud and directly impacts the mounting plate 103 and the back of the protective plate 104, this water flow action causes the protective plate 104 to generate a certain amount of rotational kinetic energy. In this process, the rotation of the protective plate 104 helps to disperse the impact force of the water flow, and the setting of the mounting plate 103 can reduce the direct impact of the water flow on the pile foundation structure, thereby reducing the uneven force on the pile foundation and the risk of excessive scouring. When the protective plate 104 rotates, two of the multiple splice rods 105 will move downward, and their ends will be plugged into the gravel cushion layer 102. In this way, the ends of the two splice rods 105 penetrate into the gravel layer, increasing the number of splice rods 105 and enhancing the anchoring effect. When the water flows over the pile foundation from above the bottom mud, only one plug-in rod 105 is inserted into the gravel cushion layer 102 to reduce the resistance of the protection plate 104 to rotate. The protection plate 104 can more easily respond to the changes in the water flow and rotate smoothly, further dispersing the impact of the water flow. When the water flows over the pile foundation along the bottom mud, two plug-in rods 105 are inserted into the gravel cushion layer 102. At the expense of a part of the rotation flexibility of the protection plate 104, such a design can increase the stability and anti-scouring ability of the gravel layer. When the water flows over the pile foundation from above the bottom mud, the insertion of the two plug-in rods 105 helps to further reinforce the gravel cushion layer 102, prevent the gravel from being carried away by the water flow, and maintain the stability of the pile foundation. Although this will slightly increase the resistance of the protective plate 104 when rotating, by increasing the number of plug-in rods 105, the gravel cushion layer 102 can be more effectively fixed and the anti-buoyancy and anti-scouring capabilities of the pile foundation can be improved, especially under strong water flow conditions. This design ensures that the gravel layer can maintain 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 (in Figure 1Taking the leftmost protective plate 104 as an example, the cleaning rod 106 can move around the pole tower pile foundation 100. By moving the cleaning rod 106, the debris or sediment on the outer wall of the pile foundation can be removed, the outer wall of the pile foundation can be kept clean, and the accumulated materials can be prevented from causing poor water flow or uneven scouring. If the flow of water is hindered by the sediment on the pole tower pile foundation 100, the scouring force in some areas is insufficient due to the poor water flow, while the scouring effect in other areas may be too strong, causing the surface of the pile foundation to be scoured deeper in some places. This uneven scouring may cause the inclination or uneven settlement of the pile foundation, increasing the risk of the pile foundation structure. In addition, using the cleaning rod 106 to clean the outer wall of the pole tower pile foundation 100 can effectively reduce the occurrence of biological corrosion. In the marine environment, organisms in the seawater (such as algae, shellfish, sponges, etc.) may attach to the outer wall of the pole tower pile foundation 100. Over time, the growth and reproduction of these organisms may cause the surface of the pile foundation to be corroded, the attachments to aggravate the corrosion phenomenon, and even affect the structural integrity of the pile foundation. This corrosion phenomenon is called biocorrosion, especially in the vicinity of water and humid environment, biocorrosion may have a serious impact on the pile foundation, reducing its service life. The cleaning rod 106 can regularly remove these biological groups and attachments by sliding and scraping the attachments on the outer wall of the pole tower pile foundation 100, thereby reducing the risk of biocorrosion. When the water flow is strong, the scraping effect of the cleaning rod 106 is more significant, which can prevent the accumulation of attachments and ensure that the outer wall of the pole tower pile foundation 100 remains smooth and clean. In the process of the end of the protective plate 104 rotating from point a to point c, the effect of the cleaning rod 106 moving around the pole tower pile foundation 100 is the same. When the impact of the water flow disappears later, the protective plate 104 will produce a reset rotation, and the cleaning rod 106 will not move during this process. The purpose of this setting is to avoid the problem of the cleaning rod 106 only moving back and forth in a small range due to the instability of the water flow. Specifically, when the impact of the water flow disappears, the protective plate 104 can effectively fix the cleaning rod 106 in a stable position through the reset rotation action. This design can prevent the cleaning rod 106 from repeatedly performing local, short-distance reciprocating motions when the water flow fluctuates or the flow velocity changes greatly, thereby avoiding the problem of dead corners that cannot be cleaned in certain areas of the pole tower pile foundation 100. If the cleaning rod 106 continues to move back and forth in a small range, it may cause attachments or sediments in certain areas to fail to be removed, thereby causing corrosion and sediment accumulation in local areas, and even affecting the stability of the pile foundation. Therefore, by allowing the cleaning rod 106 to stop moving after the water flow impact disappears, it can ensure that the cleaning work is uniform and effective in the entire range, avoiding potential risks caused by the cleaning rod 106 being unable to reach certain positions. Furthermore, when any one of the protective plates 104 is impacted by the water flow and rotates, a preset rotational force will be given to other protective plates 104, thereby achieving a linkage effect between multiple protective plates 104.On the pile foundation of the protective plate 104 that has generated a certain rotation amplitude, a preset rotation force is given to it. When the impact force of the previous water flow is weak and the rotation amplitude of the protective plate 104 is small, when the protective plate 104 that rotates later receives the water flow with a large impact force, the latter's rotation force will be transmitted to the protective plate 104 that rotates previously. Not only does it allow the protective plate 104 to continue to rotate after the previous rotation, but it also allows the corresponding plug-in rod 105 to continue to move downward for a certain distance, thereby compensating for the lack of downward movement of the plug-in rod 105 to a certain extent. In this way, when the impact of the water flow is weak, the plug-in depth can be effectively increased, and the anchoring force of the gravel cushion layer 102 can be improved, so as to better stabilize the pile foundation, and the cleaning rod 106 can continue to slide along the predetermined path to avoid being stuck or stagnant under the change of the water flow impact, thereby ensuring that the cleaning rod 106 can continue to effectively clean the outer wall of the pole tower pile foundation 100. Through the rotation linkage between the protective plates 104, the cleaning rod 106 can stably slide along the preset track to ensure that the cleaning effect is uniform and the coverage is comprehensive. Furthermore, the protective plate 104 is integrated on the mounting plate 103, and the mounting plate 103 is fixed to the pole tower pile foundation 100 by fasteners, which simplifies the installation process and makes the maintenance and replacement of the device more convenient. The present application provides a solid and stable support by pre-burying the pole tower pile foundation 100 in the underwater mud and filling it with a gravel cushion layer 102. The device uses the rotation of the protective plate 104 to absorb and disperse the impact force of the water flow, reduce the direct scouring of the water flow on the pile foundation, and anchor the gravel cushion layer 102 by the plug-in rod 105 to enhance the stability and anti-scouring ability of the pile foundation. The design of the cleaning rod 106 can effectively clean the sediment on the outer wall of the pole tower pile foundation 100, avoid biological corrosion, and ensure that the water flow is not obstructed. It effectively prevents the influence of seabed scouring on the pile foundation, especially under the action of waves and tides, the pile foundation is prone to uneven scouring, resulting in settlement or instability. Through the technical solution of the present application, the long-term stability of the tower pile foundation 100 can be ensured in a changeable marine environment, and structural instability caused by water scouring can be avoided.

[0023] As a further solution 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 provided at the top and bottom of the mounting plate 103, drainage ports 203 are respectively provided at both sides of the mounting plate 103, and a drainage plate 204 extending into the drainage port 203 is connected to the bottom of the mounting plate 103; By setting the spring a201, the mounting plate 103 is connected to the bracket 200 by rotation, and the spring a201 is connected between the mounting plate 103 and the bracket 200 to achieve the adaptive adjustment of the mounting plate 103 under the impact of water flow. The design of the spring a201 can not only provide the resilience of the mounting plate 103, but also automatically adjust the position of the mounting plate 103 when the impact force of the water flow changes, ensuring that it is always in an effective scouring protection state. The top and bottom of the mounting plate 103 are respectively provided with a plurality of scouring ports 202, which can guide the water flow to flow in a specific direction when impacting the pole tower pile foundation 100, reducing the direct scouring of the pile foundation by the water flow. By opening the drainage ports 203 on both sides of the mounting plate 103, the water flow can be quickly directed to the drainage plate 204, further dispersing the impact force of the water flow, reducing the concentrated impact of the water flow, and effectively preventing the pile foundation from being subjected to excessive scouring. The setting of the guide plate 204 can guide the water flow to a safe area, avoiding the impact of the water flow directly acting too much on the outer wall of the pole tower pile foundation 100, thereby reducing the potential threat of scouring to the pile foundation structure. In addition, when the water flows through these scouring ports 202, the flow direction and speed of the water flow will exert a certain force on the protective plate 104, promoting the rotation of the protective plate 104, and effectively allowing the plug-in rod 105 to be plugged into the gravel cushion layer 102. The end of the plug-in rod 105 gradually penetrates into the gravel cushion layer 102 as the intensity of the water flow changes, and the stability and anti-scouring ability of the gravel cushion layer 102 are enhanced through the tight locking of the particles.

[0024] As a further solution of the present invention, the anti-scour component includes a connection groove 205 opened on one side of the mounting plate 103, and the plug rod 105 is slidably connected to the connection groove 205, wherein 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; By setting the connecting rod 206, when the protective plate 104 is impacted by the water flow and its end rotates from point a to point b (counterclockwise), the protective plate 104 will press down a plug-in rod 105 located in the middle position through the connecting rod 206, allowing the plug-in rod 105 to move downward, thereby effectively anchoring the gravel cushion layer 102 and enhancing the stability and anti-scouring ability of the pile foundation.

[0025] As a further solution of the present invention, the anti-scouring component also includes a gear a207 rotatably connected to the connecting groove 205, and racks a208 meshing with the gear a207 are respectively connected to both sides of the plug-in rod 105 located in the middle, and racks b209 meshing with the gear a207 are respectively connected to the two plug-in rods 105 located on both sides; By setting the gear a207, when the protective plate 104 is impacted by the water flow and its end rotates from point a to point c (clockwise), the protective plate 104 pulls a middle plug rod 105 upward through the connecting rod 206. During this process, the other two plug rods 105 can be moved downward through the rack a208, gear a207 and rack b209 and inserted into the gravel cushion layer 102. This design can effectively enhance the anchoring effect when the water flow is about to impact the pole tower pile foundation 100 along the bottom mud surface, further stabilize the gravel cushion layer 102, prevent the loss of gravel, and improve the anti-scouring ability of the pile foundation.

[0026] As a further solution of the present invention, a rack c300 is slidably connected to one side of the mounting plate 103, the clearing rod 106 is connected to the rack c300, and the racks c300 on multiple mounting plates 103 can form an annular gear structure, and a rack d301 is connected to the middle plug rod 105, and a gear b302 extending into the connecting groove 205 and meshing with the rack d301 is provided on the mounting plate 103, and a gear c303 meshing with the rack c300 is provided on one side of the gear b302; By setting the rack d301, when the protective plate 104 rotates counterclockwise through the connecting rod 206 to move the middle plug-in rod 105 downward, the rack d301 follows and moves downward. At this time, the gear b302 rotates to rotate the gear c303, and the rack c300 can slide along the outer wall of the tower pile foundation 100, so that the cleaning rod 106 can scrape the outer wall of the tower pile foundation 100, effectively cleaning the sediment or debris attached to the outer wall of the pile foundation.

[0027] As a further solution of the present invention, a frame body 304 is connected to one side of the mounting plate 103, a connecting shaft a305 is connected to the frame body 304, a connecting shaft b306 is rotatably connected inside the connecting shaft a305, the gear b302 is arranged on the connecting shaft b306, a lead screw 307 is arranged 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, the 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; By setting a connecting shaft b306, when the rack d301 moves downward to rotate the gear b302, 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 touch the limit block 309 and slide into the limit groove 310 until the limit block 309 is engaged in the limit groove 310. When the gear b302 continues to rotate, it can contact the side wall of the limit block 309 through the limit protrusion 312 and drive the limit block 309 to rotate, so as to rotate the gear c303 through the limit block 309 and the limit 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, and the other protective plates 104 will not be rotated through the rack c300 when they are not subjected to the impact force of the water flow, thereby avoiding unnecessary rotation of other protective plates 104 that are not impacted by the water flow when there is no actual need. In addition, when the impact force of the subsequent water flow subsides and the protective plate 104 is reset by the force of the spring a201, 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 idle in the gear c303, preventing the rack c300 from also resetting and sliding, thereby ensuring that the cleaning rod 106 can continue to effectively clean the outer wall of the tower pile foundation 100.

[0028] As a further solution of the present invention, a connecting rod 400 is slidably connected to the frame 304, a spring c401 is connected between the connecting rod 400 and the frame 304, a side opening 402 is opened on the middle plug-in rod 105, one end of the connecting rod 400 extends into the side opening 402, the bottom of the connecting rod 400 is connected to a limiting frame 403, the gear b302 is slidably connected to the connecting shaft b306, and the gear b302 is rotatably connected to the limiting frame 40 3, a sleeve 404 is provided on one side of the gear c303, the sleeve 404 is rotatably connected to the frame body 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 to the mounting plate 103, one end of the traction frame 407 extends into the side opening 402, two limiting plates 408 are connected to the side opening 402, and a gap is provided between the two limiting plates 408 through the connecting rod 400; By setting the connecting rod 400, the connecting rod 400 is controlled by the position of the spring c401, so that the gear b302 can be engaged with the rack d301. If the protective plate 104 rotates clockwise, the middle plug-in rod 105 moves upward, and the connecting rod 400 can be pushed through the side opening 402, so that the connecting rod 400 can pass through the limit frame 403 to allow the gear b302 to slide along the connecting shaft b306 and leave the rack d301. At the same time, the traction frame 407 is restricted by the limit plate 408 and moves with the middle plug-in rod 105. 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 this setting does not simply set a ratchet set between the connecting shaft b306 and the connecting shaft a305 to achieve the one-way sliding of the gear c303. In this application, the cleaning rod 106 can slide along the outer wall of the tower pile foundation 100 only when the water flow hits the protective plate 104. The purpose is to fully utilize the impact force of the water flow to clean the outer wall of the tower pile foundation 100. A ratchet group is set between the connecting shaft b306 and the connecting shaft a305 to replace the limit block 309, the limit groove 310 and other components. Here is an example: the middle plug-in rod 105 moves downward through the gear b302, the connecting shaft b306, the ratchet group connecting shaft a305 and the gear c303 to allow the rack c300 to slide. When the plug-in rod 105 is reset, the connecting shaft b306 rotates idly in the connecting shaft a305 and does not affect the position of the rack c300; when the middle plug-in rod 105 moves upward, the gear b302 and the connecting shaft b306 rotate idly in the connecting shaft a305 due to the setting of the ratchet group. Without affecting the position of the rack c300, when the protective plate 104 is reset and rotated, the gear b302, the connecting shaft b306, the ratchet group connecting shaft a305 and the gear c303 allow the rack c300 to slide. Although such a setting can also achieve unidirectional sliding of the rack c300, the rack c300 can only slide when the protective plate 104 is reset and rotated after clockwise rotation, that is, the sliding force of the rack c300 comes from the spring a201. If the potential energy of the spring a201 is used to drive the sliding of the rack c300 and the cleaning rod 106, it is not enough to scrape the dirt on the outer wall of the pole tower pile foundation 100. For this reason, the above-mentioned connecting shaft a305, connecting shaft b306, limit block 309, traction rope 406 and other multiple components are set in this application, which can give full play to the impact force of the water flow to clean the outer wall of the pole tower pile foundation 100.

[0029] As a further solution 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; By setting the ratchet mechanism 410, when the traction frame 407 moves upward, the traction shaft 405 can be rotated by pulling the traction rope 406. 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, the ratchet mechanism 410 can be used to rotate the connecting pipe 409 and the gear c303. At this time, the rack c300 slides. When the protective plate 104 is subsequently reset and rotated, the sleeve 404 is reset and rotated by the potential energy of the spring d411 to rewind the traction rope 406 again. The setting of the ratchet mechanism 410 allows the sleeve 404 to idle on the outer wall of the connecting pipe 409 without affecting the gear c303 and the rack c300, thereby avoiding the problem that the rack c300 also generates reset sliding and only slides back and forth in one area and cannot completely remove the corrosion on the outer wall of the pole tower pile foundation 100. It is worth mentioning that the purpose of the ratchet mechanism 410 provided here is to allow only the sleeve 404 to perform reset rotation, and will not drive the rack c300 to slide when the plug rod 105 generates reset movement. The function of the ratchet mechanism 410 is to ensure that the sleeve 404 can automatically reset when the protective plate 104 is reset, thereby retracting the traction rope 406 and restoring the sleeve 404 to its original position.

[0030] As a further solution of the present invention, the connecting shaft b306 includes a rotating shaft a500 rotatably connected to the connecting shaft a305, the rotating shaft a500 is rotatably connected to the rotating shaft b501, the gear b302 is slidably connected to the rotating shaft a500, the lead screw 307 is connected to the rotating shaft b501, the connecting shaft a305 is slidably connected to the damping rod 502, a spring e503 is connected between the damping rod 502 and the connecting shaft a305, a damping groove 504 is provided 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; By setting the damping rod 502 and the damping groove 504, the damping rod 502 cooperates with the damping groove 504 under the force of the spring e503, and a certain friction 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 friction force formed will be. When the gear b302 and the rotating shaft a500 rotate, the rotating shaft b501 can be rotated by the friction force, which is enough to make the gear c303 and the cleaning rod 106 slide, and the outer wall of the pole tower pile foundation 100 is cleaned by the cleaning rod 106. In actual protection work, after one of the protection plates 104 rotates, the other protection plates 104 also rotate due to the impact of the water flow. Since the previous protection plate 104 has rotated at this time, the limit rod is inserted into the limit groove 310. The protection plate 104 that rotates later will also allow the corresponding limit rod to be inserted into the limit groove 310. At this time, a conflict will occur. For this purpose, the rotating shaft a500, the rotating shaft b501, the damping rod 502, the damping groove 504 and the spring e503 are provided. A protective plate 104 will also cause the rack c300 to slide. During this process, if the previously rotated protective plate 104 has not rotated to the extreme position, the protective plate 104 will rotate a certain angle again, allowing the plug-in rod 105 to penetrate deeper into the gravel cushion layer 102 to strengthen the anchoring until the friction between the damping rod 502 and the damping groove 504 is broken. If the previously rotated protective plate 104 has rotated to the extreme position, the impact force of the water flow is greater than the friction between the damping rod 502 and the damping rod 502, and the friction will also be broken to rotate. It is worth noting that at this time, whether the damping groove 504 and the damping rod 502 corresponding to the previously rotated protective plate 104 are detached, or the damping groove 504 and the damping rod 502 corresponding to the rear rotating protective plate 104 are detached, it will not affect the overall protection effect. Whether the impact force of the water flow is lighter or heavier, it will give the rack c300 a sliding force, provide cleaning ability for the cleaning rod 106, and effectively avoid interference between multiple protective plates 104.

[0031] As a further solution of the present invention, the inner wall of the rotating shaft b501 is connected with a magnetic strip 505, which is magnetically attracted to the trapezoidal portion of the damping rod 502; The friction force is further enhanced by providing the magnetic strip 505. The magnetic attraction can increase the friction force between the damping rod 502 and the damping groove 504 to a certain extent, so that the movement of the rack c300 can fully follow the movement of the protective plate 104.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
