Description

Technical Field

[0001] This utility model relates to the field of civil aircraft test flights, and in particular to a wind speed warning device for issuing warnings when wind speed exceeds the standard, and an antenna equipped with the wind speed warning device. Background Technology

[0002] Civil aircraft (sometimes simply called civil aircraft) need to undergo flight testing in various environments. During flight testing, ground support equipment needs to be set up to support the normal conduct of the test mission. Some of this support equipment needs to transmit and receive signals to communicate with other equipment, and therefore requires outdoor antennas such as those for VHF air-to-ground communication systems and trunked radio communication systems. The support equipment communicates via these antennas, and such antennas are also called civil aircraft flight test support antennas.

[0003] In actual civil aircraft test flights, the antennas mentioned above are mostly temporary antennas erected to support special missions. Therefore, these antennas are usually not very sturdy. In the event of strong winds or other extreme weather conditions, technicians need to determine whether these outdoor antennas need to be temporarily disassembled and stored to avoid damage to the antennas or antennas falling off and injuring equipment or personnel.

[0004] Technicians typically consult meteorological professionals to prepare for severe weather, but it is difficult to predict sudden, strong winds in advance. Therefore, there is a need for equipment that can detect the current wind speed in real time and issue an alarm when the wind speed exceeds the specified value to promptly remind staff to take appropriate measures.

[0005] Existing wind speed warning devices primarily use electronic components and related circuits to detect wind speed and determine whether a warning is needed based on the detected wind speed. However, wind speed detection and warning systems using such circuits are prone to causing radio interference to antenna signal communications, which could potentially affect the safety of aircraft test flights. Utility Model Content

[0006] This invention was made in view of the above-mentioned problems, and its purpose is to provide a wind speed warning device that does not affect the communication function of the antenna, and an antenna equipped with the wind speed warning device.

[0007] To achieve the above objectives, this utility model provides a wind speed warning device, comprising: a guide portion rotatable about a first axis; and a warning portion disposed on the guide portion, wherein the warning portion includes a wind-driven component, the wind-driven component being rotatably supported on the guide portion about a second axis intersecting the first axis, the guide portion including a wind-facing component, and driving the wind speed warning device to rotate to a wind-facing state when the wind-facing component is subjected to wind force, wherein the wind volume flowing through the wind-driven component along the second axis per unit time is the largest in the wind-facing state, and the wind-driven component starts to rotate when the wind volume per unit time exceeds a predetermined value, so as to generate at least one of an audible warning message and a visual warning message.

[0008] According to this utility model, the wind speed warning device, by setting the wind-driven part in the warning unit to start rotating when the wind speed exceeds a specified target value, can provide timely warnings when the wind speed exceeds the limit without using any electronic devices. Furthermore, especially when configured to transmit warning information through both auditory and visual means, personnel can receive the warning information whether they are near or far from the device, avoiding damage to the antenna due to delayed detection. In addition, by incorporating a guide unit, the wind speed warning device can automatically adjust to the optimal state for the wind-driven part based on the wind direction, thereby improving the reliability of the device's wind speed warning.

[0009] Furthermore, in the wind speed warning device of this utility model, preferably, the wind turbine has multiple blades arranged circumferentially around the second axis and rotates as the wind turbine rotates.

[0010] Furthermore, in the wind speed warning device of this utility model, preferably, the warning unit further includes a holding unit, the wind-driven component is rotatably supported on the guide unit via the holding unit, the holding unit is provided with an impact member, and the warning unit emits a sound by colliding with the plurality of blades through the impact member.

[0011] According to the wind speed warning device with the above structure, when the wind speed exceeds the standard, multiple blades on the wind turbine rotate around the second axis and collide with the impact member set on the holding part to make a sound, thereby reminding the staff through sound warning information.

[0012] Furthermore, in the wind speed warning device of this utility model, it is preferred that at least two of the plurality of blades are of different colors.

[0013] According to the wind speed warning device with the above structure, when the wind speed exceeds the limit, multiple blades on the wind turbine rotate around the second axis. Since at least two of the blades are a different color, the rotation creates a visual effect of different colored blades moving, making it easier to determine whether the wind turbine is rotating compared to when all the blades are the same color. In particular, when personnel are at a distance from the wind turbine, it is easier to make a judgment based on this visual effect, thus facilitating timely assessment and appropriate action.

[0014] Furthermore, in the wind speed warning device of this utility model, it is preferable that the wind-driven component rotates with rotational resistance between itself and the holding part, and when the wind volume per unit time is greater than the specified value, the wind-driven component can overcome the rotational resistance and start to rotate.

[0015] Furthermore, in the wind speed warning device of this invention, preferably, the rotational resistance is adjustable.

[0016] The wind speed warning device with the above structure, by configuring the aerodynamic body to rotate with rotational resistance, ensures that the aerodynamic body is not easily rotated by disturbances other than wind when the wind speed is not exceeded, reducing the risk of affecting the flight test process due to false warnings. Furthermore, by making the rotational resistance adjustable, the same device can be applied to multiple antennas with different wind speeds as warning targets. This saves manufacturing costs.

[0017] Furthermore, in the wind speed warning device of this utility model, it is preferred that the holding part includes: a cylindrical part that surrounds the plurality of blades radially outward from the second rotating shaft; and the impact member disposed on the inner wall surface of the cylindrical part.

[0018] Furthermore, in the wind speed warning device of this utility model, it is preferable that the impact member is located radially inside the plurality of fan blades with the second rotating shaft as the center.

[0019] According to the above-described structure of the wind speed warning device, the impact component can be selectively set on the outside or inside depending on the actual situation of the structure and installation location of the wind-driven body and the wind speed warning device, thereby increasing the freedom of setting the wind speed warning device.

[0020] Furthermore, in the wind speed warning device of this utility model, preferably, the wind speed warning device further includes a main rod, the guide part is located above the main rod and is rotatably supported on the main rod around the first axis.

[0021] The wind speed warning device with the above structure can be further raised by setting a main pole, making it easier for staff to observe the above visual warning information from below.

[0022] (Utility Model Effect)

[0023] According to this invention, a wind speed warning device installed on a civil aircraft flight test support antenna uses a purely mechanical structure to issue warnings when wind speeds exceed the limit. This protects the antenna from strong winds while avoiding interference with the antenna's communication function caused by using electronic devices to measure wind speed. Furthermore, the wind speed warning device can convey warning information through both auditory and visual means, ensuring that ground personnel at the flight test site receive timely and accurate warnings regardless of their distance from the antenna. Additionally, the device can be adjusted to handle wind speeds at different target sizes, and its high degree of flexibility in setting contributes to cost savings. Attached Figure Description

[0043] Below, in conjunction with Figure 1 and Figure 2 One embodiment of this utility model will be described.

[0044] Figure 1 The image shows one embodiment of a wind speed warning device.

[0045] The wind speed warning device in this embodiment is an antenna (e.g., its top) installed on equipment (e.g., civil aircraft flight test support equipment) and provides a warning when the wind speed exceeds a specified value. Figure 1 As shown, the wind speed warning device of this embodiment mainly includes a guide unit and a warning unit disposed on the guide unit.

[0046] (Guiding Unit)

[0047] The guide unit in this embodiment includes a tail fin 1, a moving rod 2, and a rotating assembly 3.

[0048] Furthermore, in this embodiment, the guide unit is connected to the main rod 4 and mounted to the antenna via the main rod 4. The main rod 4 is, for example, a metal rod made of stainless steel. With the wind speed warning device of this embodiment mounted to the antenna, the main rod 4 is positioned perpendicular to the horizontal ground. The lower end of the main rod 4 is fixedly connected to an antenna (not shown), and the upper end is connected to and supports the guide unit. The specific connection method between the main rod 4 and the guide unit will be described later.

[0049] The tail fin 1 is, for example, a stainless steel plate. When the wind speed warning device is mounted to the antenna in this embodiment, the surface of the tail fin 1 is perpendicular to the horizontal ground. When viewed along a direction orthogonal to the surface of the tail fin 1, the tail fin 1 is rectangular and has a large surface area. The tail fin 1 is connected to a movable rod 2 at its lower end. When the wind speed warning device is placed in a windy environment, the pressure exerted by the wind on the tail fin 1 drives the movable rod 2 connected to the tail fin 1 to rotate.

[0050] The movable rod 2 is, for example, a metal rod made of stainless steel. In the embodiment where the wind speed warning device is installed on the antenna, the movable rod 2 is positioned so that its extension direction is parallel to the horizontal ground. The bottom of the movable rod 2 is connected to the top of the sleeve 7, which will be described later.

[0051] Hereinafter, the end of the moving rod 2 that connects to the tail fin 1 will be referred to as the tail, and the opposite end will be referred to as the head. In addition, the direction of extension of the moving rod 2 will sometimes be referred to as the left-right direction, with the tail side as the left and the head side as the right.

[0052] like Figure 1As shown, a triangular arrowhead 13 for indicating wind direction is provided at the head of the moving rod 2. However, the arrowhead 13 is not limited to the shape described above; it can also be any shape that facilitates direction indication, such as an arrow. Furthermore, the arrowhead 13 is not mandatory and can be omitted.

[0053] When viewed along a direction orthogonal to the surface of the tail fin 1, the height of the moving rod 2 is relatively small; in other words, the moving rod 2 is flat in the vertical direction. Preferably, the sum of the area of ​​the portion of the moving rod 2 from its axis of rotation about the main rod 4 to its head and the area of ​​the arrowhead 13 is less than the area of ​​the tail fin 1. That is, when wind blows along the surface of the plate perpendicular to the tail fin 1 towards the guide structure, the wind-receiving area on the tail fin 1 is greater than the wind-receiving area on the moving rod 2. With this structure, it can be ensured that the tail fin 1 drives the moving rod 2 to perform the guiding function when wind blows.

[0054] The rotating assembly 3 includes a bearing and an outer cylinder. The bearing is, for example, a rolling bearing with low friction torque, having an outer ring and an inner ring. The outer cylinder is formed as a cylinder that opens downwards and closes at the top. The upper end of the outer cylinder is fixedly connected to the bottom of the sleeve 7, for example, by welding, and engages with the outer ring of the bearing in a manner that restricts relative movement. The inner ring of the bearing is fixedly connected to the main rod 4 in a manner that restricts relative movement. According to the above structure, the moving rod 2 can rotate around the main rod 4 via the sleeve 7 and the rotating assembly 3. Hereinafter, the axis of rotation of the moving rod 2 will be referred to as the first axis of rotation (equivalent to the first axis of this invention).

[0055] When wind blows in the environment where the wind speed warning device of the embodiment is located, the wind exerts pressure on the aforementioned guide unit. As described above, the pressure component perpendicular to the tail fin 1 has a larger wind-receiving area on the tail fin 1, and therefore the generated wind pressure torque drives the movable rod 2 to rotate through the tail fin 1 until the head of the movable rod 2 faces the direction from which the wind is blowing (i.e., the wind direction). At this time, since the forces on both sides of the tail fin 1 are balanced, the movable rod 2 is stabilized in this position. For example, when the wind blows from the southeast, the wind pressure acting on the guide unit generates a torque on the tail fin 1 that drives the lower movable rod 2 to rotate, resulting in the movable rod 2 being stabilized with its head facing southeast.

[0056] In the following description, the state in which the moving rod 2 is rotated in the wind so that its head faces the direction from which the wind is blowing is called the windward state.

[0057] (Early Warning Unit)

[0058] The warning unit is used to issue a warning to personnel when the wind speed in the environment where the antenna equipped with the wind speed warning device is located exceeds a specified value. The warning unit in this embodiment includes a holding unit and a warning unit.

[0059] Figure 2This is a perspective view showing the structure of the retaining part supporting the warning part in the wind speed warning device according to the embodiment. Figure 1 and Figure 2 As shown, the retaining part includes a sleeve 7, a first bracket 9, and a second bracket 10.

[0060] The sleeve 7 is formed as a cylinder extending in the left-right direction. In this embodiment, the sleeve 7 extends from near the end of the head of the abutment rod 2 of the tail fin 1 to near the head of the abutment rod 2 in the left-right direction. The sleeve 7 is connected to the abutment rod 2 at the top and to the rotating assembly 3 at the bottom.

[0061] A plurality of (six in the figure) levers 8 are provided at the end of the sleeve 7 near the tail of the moving rod 2. Each lever 8 is arranged circumferentially, with a portion fixed to the inner wall of the sleeve 7 inside the sleeve 7 and another portion fixed to the left end face of the sleeve 7 outside the sleeve 7. The levers 8 can collide with the second blades 6 of the rotating second blade 6 (described later). The end of each rotating second blade 6 near the lever 8 collides with the lever 8 and produces a sound. Therefore, the levers 8 are preferably made of a material that deforms during the collision and returns to its original shape after the collision.

[0062] The first support 9 and the second support 10 are arranged in a left-right direction inside the sleeve 7. The first support 9 includes, for example, three support plates 91. One end of the three support plates 91 is connected and fixed to the inner wall of the sleeve 7, and the other end is fixedly connected to the first rotating body 11 of the rotating shaft described later, thereby supporting the first rotating body 11 in a way that restricts its rotation.

[0063] The second support 10 includes support rods 101 and a pivot bearing 102. For example, the second support 10 includes two support rods 101 arranged at equal intervals in the circumferential direction relative to the pivot bearing 102. One end of each support rod 101 is connected and fixed to the inner wall of the sleeve 7, and the other end is connected and fixed to the outer circumferential surface of the pivot bearing 102. Thus, when viewed along the extension direction of the sleeve 7, the plurality of support rods 101 support and hold the pivot bearing 102 at the center of the sleeve 7.

[0064] The pivot bearing 102 is formed in a cylindrical shape, and the second rotating body 12 of the pivot, described later, can pass through the pivot bearing 102 and be supported by the pivot bearing 102 to be able to rotate.

[0065] The warning unit of this embodiment includes a plurality of first fan blades 5, a plurality of second fan blades 6, and a rotating shaft for connecting the aforementioned fan blades.

[0066] For example, a single-piece hinge, such as... Figure 2As shown, the rotating shaft of this embodiment includes a first rotating body 11 and a second rotating body 12. When the rotation of either the first rotating body 11 or the second rotating body 12 is restricted, the other rotating body can rotate relative to the restricted rotating body.

[0067] As described above, the first rotating body 11 of the shaft is supported on the first bracket 9 in a manner that restricts rotation, while the second rotating body 12 is supported through the second bracket 10 and is able to rotate.

[0068] In addition, Figure 2 The first rotating body 11 and the second rotating body 12 shown are formed into cylinders with a fixed diameter, but the shape of the first rotating body 11 and the second rotating body 12 is not particularly limited. For example, the second rotating body 12 only needs to have a part that can be supported and rotated by the second support 10, and the rest can be a prism with a polygonal cross-sectional shape, etc.

[0069] The warning unit of this embodiment has three first blades 5 disposed on the second rotating body 12. Each first blade 5 is formed of, for example, a metal with high strength and strong corrosion resistance, and is connected and fixed to the second rotating body 12 by means of welding or the like, so that it can rotate integrally with the second rotating body 12. In addition, each first blade 5 is formed with the same shape and is formed in the left-right direction between the first support 9 and the second support 10, and is inclined at the same angle in the circumferential direction in a propeller-like structure. Here, each first blade 5 may adopt the same or similar shape as the blades used in conventional anemometers.

[0070] According to the first blade 5 of the above structure, when wind blows towards the first blade 5, the pressure difference formed on the windward and leeward sides of each first blade 5 can generate a torque that drives the first blade 5 to rotate, thereby causing the first blade 5 to rotate. Hereinafter, the axis of rotation of the first blade 5 will be referred to as the second axis of rotation (equivalent to the second axis of this utility model).

[0071] The warning unit in this embodiment includes three second blades 6 (equivalent to the blades of this invention). Each second blade 6 is made of, for example, a metal with high strength and strong corrosion resistance, and one end is fixedly connected to the second rotating body 12 by welding or other means, so that it can rotate integrally with the second rotating body 12. In addition, the second blades 6 are arranged at equal intervals in the circumferential direction and are located on the left side of the second support 10 in the left-right direction.

[0072] Each second blade 6 is formed in the shape of a flat plate, with its length direction perpendicular to the second rotation axis and its width direction parallel to the second rotation axis. Preferably, the left end face of each second blade 6 is formed as a plane orthogonal to the second rotation axis. Thus, when wind blows over the second blade 6, it is difficult for the wind to form a pressure difference on the second blade 6, so that the second blade 6 is hardly driven to rotate under the action of wind force.

[0073] Therefore, when the wind blows towards the first fan blade 5, it drives the first fan blade 5 to rotate, thereby causing the second rotating body 12, which rotates together with the first fan blade 5, to rotate, and then the second fan blade 6, which rotates together with the second rotating body 12, to rotate.

[0074] In addition, in this embodiment, when the second blade 6 is installed on the rotating shaft, each second blade 6 is located on the left side of the sleeve 7 and can collide with the portion of the plurality of paddles 8 provided on the sleeve 7 located outside the sleeve 7.

[0075] Furthermore, since both types of fan blades (first fan blade 5 and second fan blade 6) rotate integrally with the second rotating body 12, the rotation axes of both fan blades are the same, namely, the second rotation axis. When the rotating shaft in the warning unit is supported and held by the first bracket 9 and the second bracket 10, the second rotation axis is set to be perpendicular to the first rotation axis and parallel to the extension direction of the moving rod 2. Specifically, the second rotation axis is set to be parallel to the horizontal ground and parallel to the wind direction through the guide unit in the wind. Thus, in the windward state, it can be ensured that the airflow along the rotation axis direction of the first fan blade 5 is as large as possible per unit time, thereby improving the accuracy of wind speed warning.

[0076] In addition, the shaft also includes a fastener (not shown), which is provided, for example, at the right end of the first rotating body 11 and is used to adjust the resistance when the first rotating body 11 and the second rotating body 12 move relative to each other. Specifically, the fastener can adjust the contact pressure between the two rotating bodies by adjusting the tightness, thereby adjusting the friction between them. Thus, when the wind force applies torque to the second rotating body 12 via the first fan blade 5 to make it rotate, the torque applied to the second rotating body 12 needs to exceed the torque value that can overcome the friction (maximum static friction) to make the second rotating body 12 start rotating. In the following description, the torque value that enables the second rotating body 12 to start rotating is referred to as the specified torque.

[0077] Therefore, when the wind speed in the environment where the wind speed warning device is located is less than the specified wind speed, the first blade 5 will not rotate, while when the wind speed in the environment exceeds the specified wind speed, the first blade 5 will start to rotate.

[0078] According to the shaft structure described above, when wind blows across the first blade 5 of the warning unit, if the wind speed is low and the torque generated by the wind on the first blade 5 on the second rotating body 12 is less than a specified torque, the second rotating body 12 will not rotate, and consequently, the second blade 6 will not rotate. When the wind speed is high enough that the torque generated by the wind on the first blade 5 on the second rotating body 12 is greater than the specified torque, the second rotating body 12 begins to rotate, and consequently, the second blade 6 and the second rotating body 12 rotate together. Hereinafter, the minimum wind speed that can drive both blades to start rotating as described above will be referred to as the specified wind speed.

[0079] The specified wind speed can be set according to actual needs. For example, it can be set based on the maximum wind speed that the antenna equipped with a wind speed warning device can withstand, or it can be appropriately set based on the wind speed that any equipment other than the antenna used for flight testing can withstand. Simultaneously, based on the set specified wind speed and the specific structure of the first blade 5 used, the torque acting on the shaft is obtained, and this torque is set as the specified torque. The specified torque can be changed, for example, by adjusting the tightness of the shaft's fasteners.

[0080] Therefore, the target wind speed (i.e. the specified wind speed) that needs to be warned can be set according to the actual situation, so that a timely warning can be issued reliably when the wind speed exceeds the specified wind speed, reducing the risk of damage to antennas and other devices due to unexpected strong winds.

[0081] In addition, the friction between the first rotating body 11 and the second rotating body 12 can prevent the first fan blade 5 and the second fan blade 6 from rotating due to their own weight or external disturbances such as device shaking. Therefore, it can better prevent false alarms caused by accidental rotation of the fan blades and improve the reliability of the alarm.

[0082] According to the above-described warning unit, when the wind speed exceeds the specified wind speed and the first fan blade 5 rotates, the first fan blade 5 drives the second fan blade 6 to rotate via the second rotating body 12. The rotating second fan blade 6 collides with the paddle 8 on the sleeve 7, producing a sound. By hearing this sound, the staff can realize that the fan blade has started to rotate and thus realize that the wind speed has exceeded the limit. In this way, the warning effect of the wind speed warning device is achieved.

[0083] Furthermore, the paddle 8 is preferably designed to produce a sound that is easily noticeable when it collides with the second blade 6. For example, the paddle 8 is made of a metal material with good elasticity, and it produces a relatively loud sound when it collides with the metal second blade 6, so that the staff can easily hear the sound of the second blade 6 colliding with the paddle 8 even in a noisy environment, and can promptly detect the rotation of the second blade 6.

[0084] Furthermore, in this embodiment, the three second blades 6 are coated with two highly distinguishable colors. Specifically, for example, one of the three second blades 6 is coated with red, the next second blade 6 adjacent to the red blade in a clockwise direction is coated with another color, such as green, which is highly distinguishable from red, and the remaining second blade 6 is coated with red, so that the final colors of the three blades are red, green, and red in sequence. By coating the second blades 6 with different colors as described above, compared with a single-colored second blade 6, a visual effect of two colors alternating movement can be produced when the second blades 6 rotate. Since the antenna of the wind speed warning device of this embodiment is often set at a high position (above the height of the test flight personnel), and as described above, the wind speed warning device is connected to the antenna via the main rod 4, thereby further raising the height of the device, when the personnel look up, they can see the color coated on the downward-facing surface of the second blades 6. Even if the personnel are far away from the wind speed warning device to be observed, they can easily determine whether the second blades 6 are rotating by observing the aforementioned visual effect.

[0085] The following describes how to use the wind speed warning device according to this embodiment.

[0086] The wind speed warning device of this embodiment is used in the antenna of equipment used in civil aircraft flight tests. The wind speed warning device is mounted on the top of the antenna of the aforementioned equipment, and the device and the antenna are securely fixed in a detachable manner.

[0087] Before conducting outdoor flight tests, the functionality of the wind speed warning device installed on the antenna is tested. Specifically, the wind speed as the warning target (i.e., the specified wind speed mentioned above) is determined based on the maximum wind speed the antenna can withstand or a wind speed predetermined by the personnel. The required torque for the rotating shaft is obtained through testing or simulation based on the structure of the first blade 5, and the drag torque is adjusted to this specified torque using fasteners. Then, for example, an environment with the specified wind speed is simulated in an indoor wind tunnel. The test unit on the device is tested to be able to rotate rapidly and guide the airflow, and whether the first blade 5 on the device can start rotating at the specified wind speed is tested.

[0088] After confirming that the wind speed warning device is functioning properly, the antenna equipped with the wind speed warning device will be placed in the corresponding outdoor location, and civil aircraft test flights will be conducted.

[0089] When unexpected abnormal weather occurs in the outdoor environment where the wind speed warning device is located, causing the wind speed to exceed the specified wind speed, the guide component of the wind speed warning device rotates under the torque generated by the wind pressure and stabilizes when the device reaches the windward position. At this time, the windward side of the first blade 5 in the warning unit of the wind speed warning device faces the direction from which the wind is blowing, and the pressure difference between the windward and leeward sides of the airflow on the first blade 5 creates torque. Since the torque generated on the first blade 5 by the wind speed at this time is greater than the aforementioned resistance torque, the wind drives the first blade 5 to rotate, and drives the second blade 6 to rotate via the second rotating body of the rotating shaft.

[0090] When the second blade 6 rotates, the red and green coated blades create a visual effect of alternating colors. Even personnel participating in the flight test, located at a distance from the wind speed warning device, can visually observe the dynamic color changes of the second blade 6 to determine if the wind speed exceeds the limit, thus achieving the effect of issuing a wind speed exceeding the limit warning. Furthermore, the frequency of the color changes can be used to roughly estimate the wind speed.

[0091] At the same time, the rotating second blade 6 collides with the lever 8 set on the sleeve 7, producing a noticeable sound. By hearing this sound, staff can determine that the wind speed is excessive. Furthermore, the frequency of the sound can be used to roughly estimate the wind speed.

[0092] In summary, when the wind speed warning device is located in an environment where the wind speed exceeds the standard, it can promptly alert staff through both sound and visual means. The alerted staff can then make a timely judgment and disassemble and store the outdoor antenna, avoiding adverse situations such as antenna deformation or damage in strong winds or antenna falling off, which could cause damage to personnel and facilities.

[0093] (Main effects of this implementation method)

[0094] According to the wind speed warning device of this embodiment, by providing a first fan blade 5, a second fan blade 6, and a rotating shaft for setting the wind speed (i.e., the aforementioned specified wind speed) that causes both fan blades to start rotating, the second fan blade 6 can start rotating when the wind speed exceeds the specified limit. Since the second fan blade 6 is made of a different color that is easily distinguishable, and a sleeve 7 equipped with a paddle 8 is provided, when the second fan blade 6 rotates, the rotating fan blade can create a visual effect in terms of color and produce a sound by colliding with the paddle 8, thereby conveying warning information through both auditory and visual means.

[0095] Therefore, by installing the wind speed warning device of this embodiment on the antenna, a warning can be issued when the wind speed exceeds the limit through a purely mechanical structure. This not only protects the antenna from strong winds by providing a wind speed warning, but also avoids interference with the antenna's communication function caused by using electronic devices to measure wind speed.

[0096] Furthermore, since the warning information is conveyed through both auditory and visual means, ground personnel conducting the test flight can receive the warning information promptly and accurately, regardless of whether they are far or close to the antenna.

[0097] In addition, the guide unit on the wind speed warning device can maximize the amount of air flowing through the first fan blade 5 per unit time, making it easier to set the device's specified wind speed and ensuring that the wind speed when the first fan blade 5 starts to rotate in the wind is the preset specified wind speed, thus improving the reliability of the device's warning.

[0098] In addition, the wind speed at which the two types of fan blades begin to rotate can be adjusted to cope with wind speeds of different sizes of warning targets. Therefore, the same device can be applied to various antennas with different wind resistance requirements, which can save costs.

[0099] (Modified Example)

[0100] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above embodiments.

[0101] For example, in the above embodiment, the sleeve 7 extends from the left to the right relative to the first axis of rotation, but the arrangement of the sleeve 7 is not limited to this. For example, the sleeve 7 may also be arranged only on the left or right side relative to the first axis of rotation. Specifically, the sleeve 7 may be arranged on the moving rod 2 and only on the left or right side relative to the first axis of rotation. In this case, the rotating component 3 in the guide unit is directly connected to the moving rod 2, and a counterweight may be arranged on the side of the moving rod 2 where the sleeve 7 is not arranged to balance the weight on both sides, preventing the moving rod 2 from wobbling due to weight imbalance when rotating.

[0102] Furthermore, the shape of the sleeve 7 is not limited to a cylindrical shape. As long as it can accommodate other components of the aforementioned warning part and retaining part, the sleeve 7 can also be formed into a cylindrical shape with a square, pentagon or other polygonal cross-section.

[0103] Furthermore, in the above embodiment, the second fan blade 6 is disposed on the outside relative to the sleeve 7 and collides with the portion of the paddle 8 that is outside the sleeve 7 to produce a sound. However, the arrangement of the second fan blade 6 and the paddle 8 is not limited to this. For example, the second fan blade 6 may be partially disposed inside the sleeve 7 and collide with the paddle 8. In this case, the paddle 8 may not include the portion that is outside the sleeve 7.

[0104] Furthermore, in the above embodiment, the first axis of rotation of the moving rod 2 is perpendicular to the horizontal ground, and the second axis of rotation of the first fan blade 5 and the second fan blade 6 is parallel to the horizontal ground, that is, the second axis of rotation is perpendicular to the first axis of rotation, but the direction of the above-mentioned axis of rotation is not limited to this. The second axis of rotation only needs to intersect the first axis of rotation. Here, "intersection" can mean that the two axes intersect in the same plane, or it can mean that the projection of the second axis of rotation in the plane where the first axis of rotation is located intersects the first axis of rotation.

[0105] Furthermore, in the above embodiment, there are three second fan blades 6, which are successively coated with red, green, and red, but the number and color of the second fan blades 6 are not limited to this. The number of second fan blades 6 can be two or more, and only two of the multiple second fan blades 6 need to be different colors with high distinguishability. For example, there could be two second fan blades 6, and the two second fan blades 6 could be coated with yellow and blue respectively. Moreover, the color on each second fan blade 6 is not limited to a single color; for example, multiple second fan blades 6 could be coated to produce a specific pattern when rotated.

[0106] Furthermore, in the above embodiment, the warning unit uses the first fan blade 5 as a component driven by wind power to detect wind speed, but it is not limited to this. As an alternative to the first fan blade 5, a wind turbine can also be used, for example. The wind turbine includes multiple blades and a hub for holding the multiple blades. The blades have an aerodynamic shape and can generate torque under the action of airflow to drive the wind turbine to rotate. Similar to the above embodiment, the hub is disposed on the second rotating body 12 in a manner that allows it to rotate integrally with the second rotating body 12. When wind blows across the wind turbine, the wind turbine rotates around the second rotation axis and drives the second fan blade 6 to rotate via the second rotating body 12, achieving the same warning effect as the above embodiment.

[0107] Furthermore, in the above embodiment, the paddle 8 disposed on the sleeve 7 strikes the second blade 6 from the outside to produce a sound, but the relative positional relationship between the paddle 8 and the second blade 6 is not limited to this. For example, the second blade 6 can also be formed, like a wind turbine, with multiple blades arranged along the outer edge of the blade seat of a circular hub structure. In this case, the paddle is radially disposed on the inner side of the multiple blades arranged along the outer edge, and the paddle can strike one end of the radially inner side of the multiple blades to produce a sound.

[0108] It should be understood that within the scope of this invention, the various parts of the embodiments can be freely combined, or the various parts of the embodiments can be appropriately modified or omitted.
