For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0047] In the description of the present application, it should be noted that unless otherwise defined, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0048] It should be noted in advance that the prior art has obvious limitations in dealing with the wind resistance stability and shock absorption requirements of floating transmission towers, including problems such as frequency ratio sensitivity, poor adaptability to movement directions, slow response speed, and high costs. These disadvantages limit the application effect of the prior art in floating transmission towers.

[0049] Therefore, an embodiment of the present invention provides a floating transmission tower. Specifically, please refer to Figure 1 , Figure 1 which shows a schematic diagram of a floating transmission tower in one of the embodiments of the present invention, including: a tower body and a limiting block. Among them,

[0050] The limiting block includes a fixed steel cable 1, a rigid coupling 2, a limiting plate 5, an electromagnetic actuator 7, and a disc damper 9;

[0051] One end of the fixed steel cable 1 is connected to the cross bracing 84 of the lower cross arm 81 of the tower body, and the other end of the fixed steel cable 1 is fixedly connected to the top surface of the limiting plate 5 through the rigid coupling 2;

[0052] The electromagnetic actuator 7 is connected to the bottom surface of the limiting plate 5;

[0053] The electromagnetic actuator 7 includes a hinge and a solenoid valve 77;

[0054] The driving end of the hinge is hinged to the disc damper 7, and the control end of the hinge is communicatively connected to the solenoid valve 77;

[0055] The solenoid valve 77 is used to generate an electromagnetic signal to control the flexibility of the hinge between the disc damper 7 and the electromagnetic actuator 7.

[0056] Specifically, the fixed cable, as a key connecting element of this application, has its upper end connected to the diaphragm 84 at the lower cross arm 81 of the floating transmission tower 8, and its lower end is fixedly connected to the limit plate 5 through the rigid coupling 2. This design ensures that this application can be stably fixed on the floating transmission tower and withstand various external loads. The rigid coupling is used to connect the fixed cable 1 and the limit plate 5 to ensure a firm connection between the two and the ability to transmit the required forces and torques.

[0057] Among them, the electromagnetic actuator 7 is used to monitor and adjust the connection flexibility of the disc damper 9 in real time. By adjusting the output force of the electromagnetic actuator, this application can achieve precise control of the movement of the disc damper, thereby realizing dynamic regulation of the tower in the roll and pitch directions. The disc damper 9 utilizes the inertia principle to absorb and disperse the kinetic energy caused by wind and waves. When the floating transmission tower is subjected to external loads, the disc damper will rotate or swing to a certain extent in the direction of its movement, thereby effectively reducing the movement amplitude of the tower.

[0058] Specifically, when the floating transmission tower is subjected to external loads (such as wind and waves), this application monitors the movement state of the disc damper in real time through the electromagnetic actuator. According to the monitoring results, the electromagnetic actuator adjusts its output force, thereby changing the connection flexibility of the disc damper. This dynamic regulation mechanism ensures that this application can respond quickly according to different external load conditions and effectively absorb and disperse kinetic energy.

[0059] The combined design of the spring anti-collision buffer and the limit rod / limiter provides a key safety protection mechanism. In extreme cases, such as when the tower shakes violently due to strong winds and high waves, the spring anti-collision buffer can absorb and disperse the impact force to prevent the tower from being damaged too much. At the same time, the limit rod and the limiter limit the movement range of the disc damper to prevent it from hitting the floating transmission tower.

[0060] Preferably, in an embodiment of the present invention, the limit block further includes a connecting rod and a plurality of spring anti-collision buffers 3, wherein,

[0061] One end of the connecting rod 6 is connected to the electromagnetic actuator 7, and the other end of the connecting rod 6 is connected to the bottom surface of the limit plate 5;

[0062] One end of the spring anti-collision buffer 3 is connected to the limit plate 5, and the other end of the spring anti-collision buffer 3 is connected to the tower body;

[0063] The limit plate is connected to the tower body through the spring anti-collision buffer 3.

[0064] Specifically, the connecting rod, as a key component connecting the limit plate 5 and the electromagnetic actuator 7, provides the necessary mechanical support. It ensures the structural integrity of the entire damping system and allows the disc damper 9 to rotate or swing within a certain range.

[0065] Among them, the spring anti-collision buffer 3 is connected between the limit plate 5 and the floating transmission tower 8, playing a key safety protection role. In extreme cases, such as in severe weather with strong winds and high waves, the spring anti-collision buffer can absorb and disperse the impact force to prevent the tower from being damaged too much.

[0066] Preferably, in an embodiment of the present invention, the spring anti-collision buffer 3 includes: a mounting fixture 31, a fixing bolt 32, a buffer piston rod 33, a buffer spring 34, and a buffer base 35, where

[0067] One end of the mounting fixture 31 is threadedly connected to the limit plate 5 through the fixing bolt 32, and the other end of the mounting fixture 31 is connected to one end of the buffer spring 34;

[0068] The other end of the buffer spring 34 is connected to the buffer base;

[0069] The buffer piston rod 33 is located inside the buffer spring 34. One end of the buffer piston rod 33 is connected to one end of the buffer spring 34, and the other end of the buffer piston rod 33 is connected to the buffer base 35.

[0070] Specifically, as Figure 2 shown, Figure 2 is the front view of the spring anti-collision buffer in one embodiment of the present invention. Among them, the mounting fixture 31 is the connecting component between the spring anti-collision buffer and the limiter 5. It is designed with holes suitable for the fixing bolt 32 to pass through to ensure a firm connection between the two. The material of the mounting fixture is usually selected as high-strength alloy to withstand the impact force from external loads.

[0071] The fixing bolt 32 is used to tightly connect the mounting fixture 31 and the limiter 5. It is usually equipped with locking devices such as nuts and washers to prevent the bolt from loosening under vibration or impact. The selection of the fixing bolt needs to consider its tensile strength and shear strength to ensure the reliability of the connection.

[0072] One end of the buffer piston rod 33 is connected to the mounting fixture, and the other end is in contact with the buffer spring (34). When an external load acts on the spring anti-collision buffer, the buffer piston rod will be compressed and drive the buffer spring to deform. The material of the buffer piston rod needs to have sufficient strength and stiffness to withstand the impact force from external loads.

[0073] The buffer spring 34 utilizes its own elastic characteristics to convert the impact force of the external load into the deformation energy of the spring, thereby absorbing and alleviating the impact. When selecting the buffer spring, its stiffness, fatigue life, and elastic recovery ability need to be considered to ensure good buffering effect under multiple impacts.

[0074] The buffer base is the fixed support part of the spring anti-collision buffer, usually installed on the floating transmission tower 8, providing stable support for the entire buffer system. The material of the buffer base needs to have sufficient strength and stiffness to withstand the forces from the buffer spring and the buffer piston rod. At the same time, the design of the buffer base also needs to consider its installation convenience and compatibility with the tower structure.

[0075] In an embodiment of the present invention, when the spring anti-collision buffer 3 is subjected to an external load force, the external load first acts on the mounting fixture 31 or the buffer piston rod 33. These components transfer the impact force to the buffer spring 34. Under the action of the impact force, the buffer spring 34 deforms. The elastic characteristics of the spring convert these external forces into the deformation energy of the spring, thereby absorbing and alleviating the external impact. When the external load disappears or decreases to a certain extent, the buffer spring 34 begins to release the stored deformation energy. The spring gradually returns to its original shape and pushes the buffer piston rod 33 back to the initial position. With the complete recovery of the buffer spring, the entire spring anti-collision buffer system returns to the initial state, ready to receive the next impact.

[0076] Preferably, in an embodiment of the present invention, the electromagnetic actuator 7 further includes a housing 72, a base 78, a core rod 711, and a proportional electromagnet 712, wherein,

[0077] One end of the base 78 is fixed to the top end inside the housing 72, and the other end of the base 78 is connected to one end of the core rod 711;

[0078] The other end of the core rod 711 is connected to one end of the solenoid valve 77;

[0079] The other end of the solenoid valve 77 is connected to the proportional electromagnet 712.

[0080] Among them, the housing is the protective layer of the electromagnetic actuator, used to accommodate and protect the internal components. The housing is usually made of high-strength and corrosion-resistant materials to ensure good performance under harsh environments.

[0081] The base is the support structure of the entire electromagnetic actuator device. It is used to fix and carry the entire electromagnetic actuator system, providing a stable installation platform for each component. The base is usually made of high-strength and corrosion-resistant materials to ensure good stability under harsh environments.

[0082] The solenoid valve adjusts the current intensity of the internal coil of the proportional electromagnet 712 according to the inclination angle information fed back by the inclination sensor 710. By controlling the magnitude of the current, the regulation of the composite magnetic field intensity can be achieved, thereby controlling the flexibility at the hinge.

[0083] The inclination sensor monitors the inclination angle change of the pole tower in real time and transmits relevant data to the solenoid valve 77 through the core rod 711.

[0084] The core rod is a connecting component between the inclination sensor 710 and the solenoid valve 77, and is used to transmit the data measured by the inclination sensor to the solenoid valve to achieve the regulation of the current intensity of the proportional electromagnet.

[0085] The proportional electromagnet generates a controllable magnetic field according to the current intensity regulated by the solenoid valve 77. The magnetic field intensity is proportional to the current, and the precise control of the composite magnetic field intensity can be achieved by adjusting the magnitude of the current.

[0086] Preferably, in an embodiment of the present invention, the electromagnetic actuator 7 further includes an inclination sensor 710 and a coil 79; the inclination sensor 710 and the coil 79 are arranged on the base.

[0087] Preferably, in an embodiment of the present invention, the electromagnetic actuator 7 further includes an electromagnetic fixing bolt 71 and a rubber washer 73. Among them, the connecting rod 6 is connected to one end of the housing 72 through the electromagnetic fixing bolt 71; the rubber washer 73 is arranged at the other end of the housing.

[0088] Specifically, as Figure 3 、 4 shown, Figure 3 is the front view of the electromagnetic actuator in one embodiment of the present invention; Figure 4 is the sectional front view of the electromagnetic actuator in one embodiment of the present invention. Among them, the fixing bolt is used to connect the connecting rod 6 with the housing 72 of the electromagnetic actuator 7. They ensure a firm connection between the two, and can withstand the forces and torques from the disc damper 9 and the floating transmission tower 8. The rubber washer is installed between the electromagnetic actuator and the disc damper, playing a role of buffering and protection. It can prevent the disc damper from causing collision damage to the electromagnetic actuator during movement, and at the same time reduce the transmission of vibration and noise.

[0089] Preferably, in an embodiment of the present invention, the electromagnetic actuator 7 further includes a permanent magnet 76, and the permanent magnet 76 is arranged around the proportional electromagnet 712.

[0090] The permanent magnet provides a constant magnetic field inside the electromagnetic actuator, and its magnetic field is superimposed with the magnetic field generated by the proportional electromagnet 712 to form a composite magnetic field for adjusting the flexibility at the hinge.

[0091] Specifically, when the electromagnetic actuator 7 operates, the inclination sensor 710 monitors the inclination change of the tower pole in real time, and transmits the relevant data to the solenoid valve 77 through the core rod 711. The solenoid valve 77 adjusts the current intensity of the internal coil of the proportional electromagnet 712 according to the inclination magnitude information fed back by the inclination sensor. The greater the inclination of roll or pitch, the solenoid valve increases the input current; the smaller the inclination, the solenoid valve decreases the input current. The proportional electromagnet 712 generates a controllable magnetic field according to the current intensity adjusted by the solenoid valve. The magnetic field intensity is proportional to the current, and the intensity of the composite magnetic field can be adjusted by adjusting the current magnitude.

[0092] The change of the composite magnetic field intensity directly affects the flexibility adjustment at the hinge. When the solenoid valve applies a high current, the total magnetic field intensity increases, the magnetic torque increases, the rigidity of the hinge point improves, and the flexibility decreases; when the solenoid valve applies a low current, the total magnetic field intensity weakens, the magnetic torque decreases, and the flexibility of the hinge point increases.

[0093] By adjusting the flexibility at the hinge, the electromagnetic actuator can achieve precise control of the movement of the disc damper 9. When the tower pole is subjected to an external load, the disc damper will rotate or swing to a certain extent in the direction of its movement, and absorb part of the vibration energy by inertia. At the same time, by adjusting the flexibility at the hinge, the present application can achieve dynamic regulation of the tower pole in the roll and pitch directions, and effectively absorb and disperse the kinetic energy caused by wind and waves.

[0094] Preferably, in an embodiment of the present invention, the hinge member includes a connecting convex groove 74 and a spherical joint 75. Among them, the disc damper 9 is hinged to the electromagnetic actuator 7 through the connecting convex groove 74 and the spherical joint 75.

[0095] Among them, the connecting convex groove is the part on the electromagnetic actuator for connecting with the spherical joint 75 of the disc damper 9. It is designed with a groove suitable for the spherical joint to be embedded to ensure stable connection and free rotation between the two. The spherical joint is the connecting component between the disc damper 9 and the electromagnetic actuator 7. It allows the disc damper to freely rotate around the hinge position within a certain range, so as to absorb and disperse the vibration energy from external loads.

[0096] The tower body of the present invention includes a lower cross arm 81, a middle cross arm 82, an upper cross arm 83 and a diaphragm 84, as Figure 5 shown, Figure 5 is the front view of the floating transmission tower pole in one embodiment of the present invention.

[0097] The lower cross arm is located near the bottom of the tower structure and is a relatively stable part of the tower. Due to its low position, its center of gravity is also relatively low, thus providing a stable support point. The lower cross arm is usually designed to be relatively thick and strong to bear the weight of the transmission line and the tower itself, as well as possible external loads such as wind and waves. The cross bracing is a transverse structural member that connects the cross arms of each layer of the tower and is used to enhance the overall stability and stiffness of the tower. In this embodiment, the cross bracing is located at the lower cross arm, providing an installation position for the shock absorption and damping system.

[0098] The middle and upper cross arms are located in the middle and top of the tower respectively and are used to support the transmission line. Their designs are relatively lightweight, but they also need to bear a certain load. Under the action of external loads such as wind and waves, the middle and upper cross arms may swing or vibrate to a certain extent.

[0099] The limit block of the present invention is installed at the position of the cross bracing 84 at the lower cross arm 81. On the one hand, the lower cross arm, as a relatively stable part of the tower structure, provides a stable support point. The shock absorption system installed here can better maintain balance and is not easily disturbed by the swing of the upper part of the tower. On the other hand, the lever arm at the position of the lower cross arm is shorter, which means that when subjected to external loads, the swing amplitude of the whole tower can be effectively controlled and reduced. This helps to improve the anti-vibration performance of the tower. On the third hand, the limit block installed on the lower cross arm can better absorb and disperse the rolling and pitching movements of the tower in the wind and waves. By adjusting the flexibility and damping characteristics of the limit block, precise control of the tower movement can be achieved.

[0100] Preferably, in an embodiment of the present invention, the disc damper 9 includes: a plurality of disc mass blocks 91, a flange 92 and a plurality of limit rods 4, wherein the disc mass blocks 91 are connected to each other through the flange 92.

[0101] Preferably, in an embodiment of the present invention, the disc damper 9 further includes a plurality of limit rods 4. The limit plate 5 is provided with limit holes 10 corresponding to the plurality of limit rods 4, and the limit rods 4 pass through the limit holes 10.

[0102] Specifically, as Figure 6 shown, Figure 6 is the front view of the disc damper in one embodiment of the present invention. Among them, the disc damper is mainly composed of a disc mass block 91 and a flange 92. The damping effect can be adjusted by changing the number of disc mass blocks. The mass blocks are connected to each other through the flange 92 to form an integral structure. The flange, as a connecting structure, ensures the stability and integrity between the disc mass blocks. At the same time, the design of the flange also facilitates the adjustment of the number of mass blocks to meet different shock absorption requirements.

[0103] The limiting rod 4 passes through the limiting hole 10 on the limiting plate 5 and is connected to the disc damper 9. This design limits the movement range of the disc damper and prevents it from hitting the floating transmission tower 8 due to excessive swinging. When the external load is small, the disc damper can swing freely to absorb small-amplitude vibrations; when the external load is large, the limiting rod will limit the swinging amplitude of the damper to prevent it from exceeding the safe range.

[0104] When the floating transmission tower 8 is subjected to external loads such as wind and waves, the vibration of the tower will be transmitted to the disc damper 9 through the connecting rod 6. The disc damper rotates or swings around the hinge point, and uses the inertia of the disc mass block to generate a damping moment, thereby offsetting the tilting force caused by the vibration.

[0105] Specifically, when the disc damper rotates, the movement of the mass block will generate a damping moment. The magnitude of this moment is directly related to the total mass of the disc mass block and its swinging amplitude. A larger mass block can provide higher inertia, effectively increasing the damping capacity of the system, and thus better absorbing vibration energy.

[0106] In an embodiment of the present invention, by changing the number of disc mass blocks, the damping effect of the damper can be flexibly adjusted. In the towers with higher voltage levels, in order to effectively suppress vibration, it is necessary to increase the number of mass blocks to provide greater inertia and damping effect.

[0107] In summary, the basic working principle of the present invention is that the total damping moment M of this application 总 is composed of the control moment of the electromagnetic actuator and the damping moment generated by the disc damper:

[0108] M 总 = M 磁 + M 圆盘

[0109] In the formula, M 磁 is the adjustment moment generated by the electromagnetic actuator, and this moment is used to dynamically adjust the flexibility and movement range of the disc damper to control the movement range of the disc damper system; M 圆盘 is the damping moment provided by the disc damper.

[0110] The damping moments of each part are defined by the following formula:

[0111] M 磁 = α·I 2

[0112] I = β·φ

[0113] M 圆盘 = -c·φ = -γ·m 总 ·φ

[0114] Wherein, α is the electromagnetic system constant, I is the internal current intensity of the solenoid valve device; β is the adjustment gain, φ is the roll or pitch angle of inclination; c is the damping coefficient, γ is the proportionality coefficient related to the characteristics of the disc damper, reflecting the contribution of per unit mass to the torque, and the total mass m of the disc damper is adjusted 总 to affect the magnitude of the damping torque provided by it.

[0115] The dynamic motion equation of the tower system is:

[0116]

[0117] Wherein, J is the equivalent moment of inertia of the tower system; C is the total damping coefficient matrix of the tower system; K is the stiffness matrix of the tower system; M 外 is the external load torque.

[0118] When the inclination angle of the floating transmission tower in the roll or pitch direction is too large, this application will perform dynamic adjustment through multiple steps to reduce the inclination angle and ensure the stability and safety of the tower system.

[0119] Specifically, the tilt sensors in the electromagnetic actuator can continuously monitor the change of the inclination angle of the tower, including the inclination angles in the roll and pitch directions. These sensors have the characteristics of high precision and fast response, and can accurately capture the minute vibrations of the tower. The tilt sensors transmit the obtained inclination angle data to the solenoid valve. This step is completed by wireless or wired means to ensure the real-time and accuracy of the data. Based on the inclination angle data, this application determines the corresponding current adjustment strategy to provide guidance for subsequent magnetic field adjustment.

[0120] According to the inclination angle size information fed back by the inclination angle sensor, the solenoid valve adjusts the current intensity of the internal coil of the proportional electromagnet. This adjustment process is realized through the control system inside the solenoid valve to ensure the accuracy and stability of the current adjustment. By adjusting the current intensity, the proportional electromagnet generates a controllable magnetic field. The magnetic field intensity is proportional to the current, so the change of the current will directly affect the intensity of the magnetic field.

[0121] Among them, the magnetic field of the proportional electromagnet is superimposed with the constant magnetic field provided by the permanent magnet to form a composite magnetic field. The change of the total magnetic field intensity directly affects the flexibility adjustment at the hinge. When the inclination angle increases, the solenoid valve increases the input current, the magnetic field torque increases, and the flexibility at the hinge decreases; conversely, when the inclination angle decreases, the solenoid valve decreases the input current, the magnetic field torque decreases, and the flexibility at the hinge increases.

[0122] While adjusting the magnetic field torque inside the electromagnetic actuator, the disc damper swings in the direction of the tower vibration under the action of inertia. This swinging process can absorb and disperse the vibration energy and effectively reduce the vibration amplitude of the tower.

[0123] In one embodiment of the present invention, the inertia of the damper can be adjusted by increasing or decreasing the number of disk masses. The greater the inertia, the more energy the damper can absorb during the swinging process; conversely, the smaller the inertia, the more sensitive the damper is to smaller amplitude vibrations. When the swinging amplitude of the disk damper approaches the design limit, the limiting rod restricts its movement range through the limiting hole. In extreme cases, the spring anti-collision buffer is activated to provide an additional restoring moment, absorb shock energy, and prevent damage to the tower structure.

[0124] The solenoid valve in the electromagnetic actuator continuously adjusts the current in the internal coil of the proportional electromagnet according to the real-time inclination change. This dynamic regulation process ensures that the system can adapt to the changes in external loads in real time. By dynamically regulating the flexibility of the hinge point and the damping effect of the disk damper, the system can accurately control the vibration amplitude of the tower. This precise regulation process relies on the feedback mechanism and adjustment strategy of the system. The swinging of the disk damper itself plays a key role in absorbing and dispersing the vibration energy of the floating transmission tower. Through this process, the solution of the present application can effectively reduce the roll and pitch vibrations of the tower.

[0125] Compared with the prior art, the beneficial effects of the embodiments of the present invention are at least one of the following:

[0126] (1) In the present application, the lower cross arm is firmly connected to the limiting plate through the fixed steel cable, and the rigid coupling is used to ensure the rigidity and stability of the connection. This design can effectively resist the action of natural forces such as external wind and water flow, and improve the overall stability of the transmission tower.

[0127] (2) The disk damper proposed in the present application is hinged to the electromagnetic actuator through the connecting convex groove and the spherical joint, and can adjust the flexibility of the damper according to actual needs. When the transmission tower is subjected to external forces, the disk damper can absorb and dissipate part of the vibration energy, reducing the swaying amplitude of the transmission tower. At the same time, the inclination sensor in the electromagnetic actuator can real-time monitor the inclination angle of the transmission tower, and control the damping force of the disk damper through the solenoid valve and the proportional electromagnet, so as to achieve precise adjustment of the posture of the transmission tower.

[0128] (3) The proportional electromagnet in the electromagnetic actuator proposed in the present application can adjust the current magnitude according to needs, so as to control the damping force of the disk damper and the flexibility at the hinge of the electromagnetic actuator. This adjustability enables the transmission tower to better adapt to the requirements under different environments and working conditions.

[0129] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention shall be subject to the appended claims.
