DETAILED DESCRIPTION

[0026] The following are specific embodiments of the present application, and the technical solutions of the present application are further described in conjunction with the accompanying drawings. The present application is not limited to these embodiments, and the following embodiments do not limit the invention involved in the claims. In addition, all combinations of features described in the embodiments are not necessarily required by the solutions of the invention.

[0027] The principles and structures of the present application are described in detail below in conjunction with the accompanying drawings and examples.

[0028] Example 1 As shown in Figure 1 , 2 , 3, 4, an anti-wind communication tower, comprising a tower pole 1, a first ring body 2 coaxially rotatably sleeved on the tower pole 1, the first ring body 2 is provided with: a first mass block 3 located on one side of the central axis of the tower pole 1, a first tail wing 4 located on the other side of the central axis of the tower pole 1 and opposite to the first mass block 3, the first tail wing 4 is used to make the first mass block 3 always face the wind direction, so as to use the reaction force generated by the mass block to offset the lateral thrust of the tower pole 1.

[0029] The tower pole 1 is the main structure of the communication tower, which is usually a vertically upward pole body used to support communication equipment. The first ring body 2 is coaxially rotatably sleeved on the tower pole 1, which adopts bearing or sliding fit structure, so that it can rotate freely around the central axis of the tower pole 1. The ring body can be arranged at the middle upper part of the tower pole 1 to avoid ground interference and approach the area where wind load action is most significant. The first mass block 3 is installed on the first ring body 2 and located on one side of the central axis of the tower pole 1, which is used to form an unbalanced counterweight. The first tail wing 4 is installed on the first ring body 2 and located on the other side of the central axis of the tower pole 1, and is opposite to the first mass block 3, which is used to sense the wind direction and adjust the rotation direction of the ring body.

[0030] In operation, the wind acts on the tail wing, which automatically adjusts the direction so that the first mass block 3 always faces the direction of the wind (i.e. the windward direction). In this structure, the tail wing plays the role of "wind vane", so that the ring body remains in a dynamic adjustment state, so that the center of gravity offset is always consistent with the wind direction.

[0031] Since the first mass 3 has a certain weight and is located on one side of the axis of the tower pole 1, under the action of the tail wing, the first mass 3 is directed towards the windward direction, and the force generated by gravity will resist the lateral force of the wind on the tower pole 1, that is, the torque generated by the mass on the tower pole 1 is opposite to the torque of the wind. In short, through the dynamic adjustment of the gravity distribution, a torque or force distribution opposite to the direction of the wind load is formed, thereby effectively offsetting part of the lateral thrust caused by the wind load.

[0032] The main influence of the wind load on the communication tower is the lateral vibration or swing; long-term stress causes structural fatigue; and in extreme cases, it may even cause communication interruption or structural instability. By automatically sensing the wind direction through the tail wing, the mass is always adjusted to the windward side, and the gravity direction adjustment can be completed without the need for an electric control system; active counteracting force: the eccentric gravity generated by the mass forms a counteracting force against the lateral thrust of the wind; simplified structure, no power required: no motor, hydraulic pressure or external energy source is needed, and the system relies on aerodynamics and gravity itself to operate.

[0033] Further, the tower pole 1 is coaxially sleeved with a second ring body 5 parallel to the first ring body 2, and the second ring body 5 is provided with: a second mass 6 located on one side of the central axis of the tower pole 1, and a second tail wing 7 located on the other side of the central axis of the tower pole 1 and opposite to the second mass 6; a reset mechanism is arranged between the first ring body 2 and the second ring body 5, and when there is no wind, the reset mechanism makes the masses of the first ring body 2 and the second ring body 5 located on the two sides symmetrically about the central axis, so that the stress of the tower pole 1 is balanced.

[0034] The tower pole 1 is coaxially sleeved with two ring bodies arranged in parallel, i.e., the first ring body 2 and the second ring body 5, which can independently rotate around the axis of the tower pole 1, and each ring body is provided with a counterweight mass and a tail wing structure. The first ring body 2 is provided with a first mass 3 located on one side of the central axis of the tower pole 1 and a first tail wing 4 located on the opposite side of the central axis. The second ring body 5 is provided with a second mass 6 located on one side of the central axis of the tower pole 1 and a second tail wing 7 located on the opposite side of the central axis and opposite to the second mass 6.

[0035] A reset mechanism is arranged between the first ring body 2 and the second ring body 5, which can be a spring assembly, a damping reset sheet, a magnetic positioning device, etc., and is designed to actively or passively make the two ring bodies return to a symmetric state when there is no wind or weak wind, i.e., the first mass 3 and the second mass 6 are located on the two sides of the central axis of the tower pole 1 respectively; the two masses are symmetrically arranged in the horizontal direction, so that the overall stress of the tower pole 1 is balanced, and the tower body is prevented from tilting or stress concentration due to unilateral eccentric weight.

[0036] In the static state of small wind speed or no wind, the tail wing cannot obtain enough wind power to drive the ring body to rotate, at this time the reset mechanism automatically resets the mass blocks of the two ring bodies to the symmetrical position. This layout makes the tower 1 center of gravity keep central, no lateral moment caused by structural tilt, ensures the foundation and tower 1 in the lowest stress state, reduces the risk of long-term material fatigue.

[0037] In the presence of obvious wind speed, the tail wing obtains aerodynamic force to drive the corresponding ring body to rotate. The first tail wing 4 senses the wind direction, and makes the first mass block 3 turn to the windward direction; at the same time, the second tail wing 7 also drives the second mass block 6 to rotate to the windward direction according to the wind direction; if the reset mechanism is designed as flexible connection (such as spring), the ring body is allowed to overcome the elastic force to rotate relatively under the action of wind force; finally, the two mass blocks can generate stronger inertia resistance force to the windward direction, effectively sharing the side thrust generated by the wind load.

[0038] The reset mechanism of the embodiment is a spring connected between the first ring body 2 and the second ring body 5. The spring is a cylindrical tension spring 8, the two ends of which are fixed on the corresponding connection parts of the first ring body 2 and the second ring body 5, for example, connected between the pull ears 9 at the opposite positions of the two ring bodies, and the spring length and stiffness can be selected according to the required reset angle and reset force of the design, and a single spring or two symmetrical springs can be provided to enhance the reset force or maintain symmetrical tension.

[0039] In the windless state, the two tail wings are not driven by wind force, and the spring is in natural tension or compression state; the spring maintains the first ring body 2 and the second ring body 5 at the initial set relative angle through the elastic force, that is, at this time, the first mass block 3 and the second mass block 6 are on the two sides of the central axis, the system center of gravity is balanced, and the tower 1 is in a static stable state without lateral unbalanced load.

[0040] In the wind state, the tail wing senses the wind direction to generate a deflection force, drives the ring body to rotate, and the ring body rotates relatively around the tower 1 after overcoming the spring elastic force, the mass block deviates to the windward direction, and plays a role of lateral inertia resistance, after the wind stops, the spring restores the elasticity, drives the ring body to rotate back to the initial angle, and realizes self-resetting.

[0041] Embodiment two As Figure 5 , 6As shown, unlike the above embodiment, the reset mechanism is a reset device using magnetic force, which comprises a first magnet 10 arranged on the first ring body 2 and a second magnet 11 arranged on the second ring body 5. The first magnet 10 is arranged on the first ring body 2 and located on the side of the first mass block 3. The second magnet 11 is arranged on the second ring body 5 and located on the side of the second tail wing 7. The first magnet 10 and the second magnet 11 are oppositely arranged in the vertical direction. The magnetic poles of the first magnet 10 and the second magnet 11 are the same. For example, the N-pole of the first magnet 10 is located on the top, and the N-pole of the second magnet 11 is also located on the bottom. They are oppositely arranged in the vertical direction, and the magnetic poles are the same, forming magnetic attraction.

[0042] In the state of no wind or weak wind, the first tail wing 4 and the second tail wing 7 are not affected by enough wind force, and the two ring bodies do not rotate. The first magnet 10 located on the side of the first mass block 3 is opposite to the second magnet 11 located on the side of the second tail wing 7 in the vertical direction. Because the magnetic poles of the two magnets are the same, magnetic attraction will be generated in the vertical direction. The magnetic attraction will attract the two ring bodies to a relatively fixed angle, so that the first mass block 3 and the second mass block 6 are located on the two sides of the central axis of the tower pole 1, and the tower body as a whole is in a state of gravity balance, keeping the tower pole 1 stable and preventing the tower pole 1 from being off-loaded or curved.

[0043] In the state of wind, the first tail wing 4 and the second tail wing 7 can sense the wind direction and drive the ring bodies to rotate. With the change of the wind direction, the two mass blocks can simultaneously or respectively face the wind direction. The magnetic attraction is overcome by the wind force, allowing the two ring bodies to rotate freely. After the wind disappears, the magnetic attraction will play a role again, automatically attracting the two ring bodies back to the original paired position and restoring the symmetrical state. In this way, the first ring body 2 and the second ring body 5 are attracted to the balance position by the magnetic attraction.

[0044] Further, the first ring body 2 is provided with a third magnet 12 on the same side of the first tail wing 4, and the second ring body 5 is provided with a fourth magnet 13 on the same side of the second mass block 6. The third magnet 12 and the fourth magnet 13 are oppositely arranged in the vertical direction, and the magnetic poles are the same, so as to attract the first ring body 2 and the second ring body 5 to the balance position by the magnetic attraction.

[0045] That is to say, on the first ring body 2, in addition to the first magnet 10 (located on the same side of the first mass block 3), a third magnet 12 is arranged, which is located on the same side of the first tail wing 4 and is arranged opposite to the first magnet 10; on the second ring body 5, in addition to the second magnet 11 (located on the same side of the second tail wing 7), a fourth magnet 13 is arranged, which is located on the same side of the second mass block 6 and is arranged opposite to the second magnet 11; the third magnet 12 and the fourth magnet 13 are arranged opposite in the up-down direction, have the same magnetic pole orientation, and realize the attraction reset of the tail wing side through magnetic attraction; the first magnet 10 and the second magnet 11 form a pair of magnetic attraction units between them, and the mass block side is reset; the third magnet 12 and the fourth magnet 13 form a second pair of magnetic attraction units between them, and the tail wing side is reset.

[0046] In the windless or light wind state, the four magnets generate magnetic attraction forces in two symmetrical directions respectively; the first and second magnets 11 are responsible for resetting the mass block side to the symmetrical position; the third and fourth magnets 13 are responsible for resetting the tail wing side to the symmetrical position; the two pairs of magnetic attraction units work together to stably attract the two ring bodies to a predetermined relative angle, that is, the first mass block 3 and the second mass block 6 are located on the two sides of the central axis of the tower 1 symmetrically; the first tail wing 4 and the second tail wing 7 are also symmetrically distributed; the whole system is in a static equilibrium state.

[0047] In the wind state, the tail wing is rotated by the wind to drive the respective ring body to rotate; the wind force overcomes the magnetic attraction force, allowing the two ring bodies to separate from the original adsorption position; the first mass block 3 and the second mass block 6 dynamically face the wind direction, acting as wind-resistant counterweights; after the wind force weakens or disappears, the magnetic force automatically attracts the ring body back to the original position, realizing the passive and self-resetting function.

[0048] The magnetic pole orientations of the two magnets (the first magnet 10 and the third magnet 12) on the first ring body 2 are opposite; the magnetic pole orientations of the two magnets (the second magnet 11 and the fourth magnet 13) on the second ring body 5 are opposite, ensuring that the magnetic attraction forces can independently form effective attraction effects in two different positions (the mass block side and the tail wing side).

[0049] The first magnet 10 is arranged on the first ring body 2 and located on the side of the first mass block 3; the third magnet 12 is also arranged on the first ring body 2 and located on the side of the first tail wing 4; the second magnet 11 is arranged on the second ring body 5 and located on the side of the second tail wing 7; the fourth magnet 13 is arranged on the second ring body 5 and located on the side of the second mass block 6; the magnetic pole orientations of the first magnet 10 and the third magnet 12 are opposite; the magnetic pole orientations of the second magnet 11 and the fourth magnet 13 are opposite; the first magnet 10 and the second magnet 11 are arranged opposite in the up-down direction and have the same magnetic pole orientation; the third magnet 12 and the fourth magnet 13 are arranged opposite in the up-down direction and have the same magnetic pole orientation.

[0050] The above-mentioned magnet arrangement is such that each pair of magnets acts independently in one angular direction, and under the action of wind, the magnetic attraction is overcome; after the wind stops, the two pairs of magnets accurately attract the ring body back to the original position according to the respective magnetic pole direction. With such an arrangement, the magnetic field distribution is more balanced, the stability and controllability of the resetting process are improved, the accuracy of the resetting and positioning is improved, the angular rigidity of the ring body in the double-direction magnetic attraction state is enhanced, the small-amplitude oscillation under light wind is prevented, and the anti-interference ability of the system in a complex wind field environment is improved.

[0051] Of course, the magnets can be arranged along the circumference of the ring body for a certain length, so that the unlike magnetic poles of the magnets on the upper and lower ring bodies have sufficient magnetic attraction and the like magnetic poles have sufficient repulsion. The ring body can be arranged on the tower pole through a rolling bearing or the like, so as to make the ring body have smaller rotational resistance.

[0052] Embodiment Three As shown in Figure 7 , 8 , the resetting mechanism includes a motor arranged on the tower pole 1, one of the first ring body 2 and the second ring body 5 is provided with a positioning marker, and the other is provided with a position detection sensor for detecting the position of the positioning marker, and the motor and the first ring body 2 or the second ring body 5 are connected through a clutch.

[0053] The reset mechanism is further optimized as an electrically controlled active reset system, mainly including a motor, a clutch, a positioning marker, a position detection sensor, and a controller. The motor is arranged on the tower pole 1, and is preferably a stepper motor, a servo motor, or a DC motor with encoder feedback. The clutch is used to transmit the motor power output to the first ring body 2 or the second ring body 5 when needed, and can be disconnected to allow the ring body to rotate freely in the non-reset state. The positioning marker is arranged on one of the first ring body 2 and the second ring body 5, such as an encoded label, a reflective sheet, a magnetic marker, or a painted mark. The position detection sensor is arranged on the other ring body, and is used to detect the relative angular position of the positioning marker, such as an optical encoder, a Hall element, a laser / capacitive angle sensor, etc. The controller is used to determine whether to trigger the motor reset action according to the deflection angle detected by the sensor. The controller or control system mentioned herein refers to an electronic device or other device or system capable of automatic control, which can issue corresponding instructions to control other devices to work after software processing based on received signals or instructions, such as a central processing unit (CPU), a microcontroller unit (MCU), a system on chipset (SoC), an application-specific integrated circuit (ASIC), a programmable logic device (PLD), a single-chip microcomputer, an industrial computer, and the like.

[0054] The motor is connected to the first ring body 2 or the second ring body 5 through a controllable clutch; thereby the motor can actively drive one ring body to rotate relative to the other ring body; the clutch can be an electromagnetic clutch, a magnetic powder clutch, or a mechanical clutch.

[0055] Under the action of wind, the first tail wing 4 and the second tail wing 7 perceive the wind direction and drive the respective ring bodies to rotate; the clutch is in a disconnected state, and the motor does not interfere with the rotation of the ring body; the ring body can naturally rotate towards the wind direction, realizing the dynamic wind resistance of the mass block.

[0056] After the wind disappears, the sensor continuously detects the relative position of the positioning marker; the controller determines that the two ring bodies are not in the symmetrical initial position; the motor is started to rotate the ring body through the clutch, so that the two ring bodies form a static balance relative to the tower pole 1, i.e., the mass blocks of the two ring bodies are located on the opposite sides of the tower pole 1; after reaching the balance, the motor stops, the clutch is disconnected, and the free state is restored to facilitate the feeling of the next wind blowing.

[0057] The marker of the embodiment is a magnetic piece 14, and the position detection sensor is a Hall sensor 15. The Hall sensor 15 can be connected with an external controller through a rotating electrical connection device such as a conductive slip ring 16.

[0058] The positioning marker is a magnetic piece 14 arranged on the first ring body 2 or the second ring body 5, which is preferably a small permanent magnet such as a neodymium iron boron magnet, a soft magnetic cylinder or a magnetic strip; and the position detection sensor is a Hall effect sensor arranged on the other ring body, which is used to detect the approach or departure of the magnetic piece 14 to determine the relative rotation angle of the two ring bodies or whether the preset reset angle is reached.

[0059] The magnetic piece 14 is fixed on the inner circle or the side wall of the first ring body 2, which is small in size and light in weight and does not affect rotation; the Hall sensor 15 is fixed on the inner side of the second ring body 5 or a matching support; when the two ring bodies are rotated to a set angle, the magnetic piece 14 approaches the Hall sensor 15 to generate a detection signal (voltage change or switch state); the controller determines whether the current state is the target angle, i.e., the mass blocks of the two ring bodies are located on the opposite sides of the tower pole 1, to decide whether to continue driving or stop the motor reset.

[0060] The Hall sensor 15 outputs a low voltage / no signal in the absence of a magnetic field; when the magnetic marker approaches, the magnetic field triggers the Hall device to output a high voltage or a switch signal; the controller continuously monitors the output signal to determine whether the reset angle is reached.

[0061] Further, the motor and the clutch are each provided as two, which control the first ring body 2 and the second ring body 5 respectively; the two motors are each arranged inside the tower pole 1 and connected with the first ring body 2 or the second ring body 5 through a respective clutch; one motor drives the first ring body 2 through a first clutch, and the other motor drives the second ring body 5 through a second clutch; the motor can be a stepper motor, a servo motor or a code-controlled motor, and the clutch is an electromagnetic clutch, a magnetic powder clutch or a mechanical clutch. The motor output shaft is connected to the corresponding ring body through a flexible coupling or a gear mesh; the clutch is used to control whether the motor is linked with the ring body, which is disconnected by default and closed only in the reset stage; the controller controls the action timing of the two motors and clutches according to the detection signal of the Hall sensor 15.

[0062] When the wind is relatively strong, the two clutches are in the disconnected state; the two motors are in a standby or low-power state; and the two ring bodies can rotate freely in response to the wind direction under the driving of the tail wing.

[0063] When the wind stops or needs to be reset, the controller detects the Hall sensor 15 signal to determine the ring body angle; start the motor and close the corresponding clutch; if both ring bodies are offset, both motors can be started simultaneously and reset independently; if only one ring body is offset, the motor can also be reset independently; stop the motor rotation after reaching the target angle, and disconnect the clutch.

[0064] On the basis of two motor distributed drive, the two motors are arranged symmetrically on both sides of the tower pole 1, so as to achieve the purpose of symmetric stress, balanced gravity and stable structure of the tower pole 1 body in installation and operation.

[0065] Specifically, the first ring body 2 is sleeved with a first ring gear 17, the second ring body 5 is sleeved with a second ring gear 18, the first ring gear 17 is engaged with a first gear 19, the second ring gear 18 is engaged with a second gear 20, the first gear 19 is connected with the first motor 21 through a first clutch, and the second gear 20 is connected with the second motor 22 through a second clutch.

[0066] When the wind is large, the first and second clutches are disconnected; the two motors do not work, and the first gear 19 and the second gear 20 are in an idle state; the first ring body 2 and the second ring body 5 rotate under the action of the tail wing, responding to the change of wind direction.

[0067] When there is no wind, the controller detects whether the two ring bodies are offset from the initial angle (i.e. whether they are symmetric about the tower pole 1 torque) through the Hall sensor 15; if reset is needed, the controller instructs to start the first motor 21, closes the first clutch, makes the first gear 19 drive the first ring gear 17 to rotate, starts the second motor 22, closes the second clutch, and makes the second gear 20 drive the second ring gear 18 to rotate; when the Hall sensor 15 detects that it has returned to the target position, the controller closes the motor and disconnects the clutch.

[0068] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.
