To address the inconvenience of separate meteorological anemometers and UAV link devices, this invention combines the meteorological anemometer and UAV link device into a single meteorological anemometer link device, which is portable and saves manpower. To solve the problem of the meteorological anemometer link device being easily blown over by sudden winds in deserts and Gobi, this invention positions the link unit at a high point, connects the link to a wind vane signal, and drives the link to rotate according to the output signal of the wind vane, so that the direction with the smallest cross-sectional area of ​​the link faces the wind.

Detailed Implementation

[0024] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0025] A specific embodiment of the present invention discloses a meteorological wind speed link device, such as... Figure 1 and Figure 2 As shown, it includes link unit 1 and wind speed unit 2. Link unit 1 is positioned above wind speed unit 2.

[0026] Wind speed unit 2 includes a wind vane 21. Link unit 1 includes a link 11 and a rotating motor 12.

[0027] Link 11 is connected to the wind vane 21 by signal. The rotating motor 12 drives link 11 to rotate according to the output signal of wind vane 21. The cross-sectional area of ​​link 11 in the windward direction is the smallest at its rotation stop position.

[0028] To address the inconvenience of separate meteorological anemometers and UAV link devices, this embodiment combines the meteorological anemometer and UAV link device into a single meteorological anemometer link device, which is portable and saves manpower. To address the issue of the meteorological anemometer link device being easily blown over by sudden gusts of wind in deserts and Gobi, this embodiment positions link unit 1 at a high point. Link 11 is signal-connected to wind vane 21. Rotating motor 12 drives link 11 to rotate based on the output signal from wind vane 21. The cross-sectional area of ​​link 11 in the windward direction is minimized at its stationary position, thus minimizing the wind force on the entire device and reducing the risk of it being blown over. Simultaneously, it ensures that link 11 maintains an optimal aerodynamic posture in dynamic wind fields, guaranteeing communication stability.

[0029] Furthermore, to address the issue of high-frequency oscillation of link 11 caused by wind at high points affecting signal pointing accuracy, the link unit 1 in this embodiment further includes a spring 14 and a link base 13, such as... Figure 2 As shown, link 11 is disposed on link base 13, and spring contact 14 is disposed between link 11 and link base 13. Exemplarily, spring contact 14 is made of steel. Specifically, as... Figure 3 As shown, multiple spring pieces 14 are configured, each spring piece 14 being arc-shaped, and the multiple spring pieces 14 together form a ring structure. The link base 13 is provided with mounting holes, and the ring structure is connected to the side wall of the mounting holes. The link 11 extends into the center of the ring structure and engages with the ring structure to reduce sway damping, keep the vibration of the link 11 low, thereby attenuating the minor vibrations of the link 11 caused by wind load, stabilizing the direction of the link 11, and not affecting the link signal quality.

[0030] Furthermore, the link base 13 also includes a base 131 and a link rod 132. The link 11 is mounted on the base 131, and the rotation motor 12 is mounted at the end of the link rod 132. The output end of the rotation motor 12 is connected to the link rod 132 via a bearing. When the rotation motor 12 receives a signal from the wind vane 21, it rotates the link rod 132 and the base 131, rotating the link 11 to the direction with the smallest cross-sectional area in the windward direction, thereby reducing wind resistance and vibration caused by wind force.

[0031] Furthermore, such as Figure 4 As shown, the wind speed unit 2 also includes a wind vane 22, which comprises a first rod 221, a second rod 222, and a telescopic sleeve 223. The first rod 221 is connected to the rotary motor 12, and a wind vane 21 is mounted on the second rod 222. The telescopic sleeve 223 is fitted between the first rod 221 and the second rod 222 to adjust the height of the wind vane 22, allowing the wind vane 21 to be positioned at different height levels for measurement. This provides wind direction data that better reflects the actual wind conditions of the link 11, improving the accuracy and adaptability of the rotary motor 12 in adjusting the link 11.

[0032] Furthermore, the wind speed unit 2 also includes a wind speed disk 23 and a wind direction axis 24, with the wind vane 21 and the wind speed disk 23 mounted on the wind direction axis 24.

[0033] The lower end of the wind direction axis 24 passes through the interior of the second rod 222. The middle part of the second rod 222 is an arc-shaped structure, and the wind vane 21 and wind speed disk 23 are located in the concave part of the arc-shaped structure.

[0034] Furthermore, it also includes a base 3, which supports the link unit 1 and the wind speed unit 2. The base 3 includes a support plate 31 and a central rod 32.

[0035] Furthermore, in order to address the problem that rigid fixation of the wind axis 24 can easily lead to stress concentration or jamming when subjected to gusts of wind, such as... Figure 5 As shown, the central rod 32 is a hollow structure, and the lower end of the wind direction shaft 24 extends into the hollow structure, allowing it to move along the central axis of the central rod 32 within the hollow structure. This absorbs some of the impact displacement and improves the stability of the device under sudden wind loads. For example, a slider 241 is provided at the end of the wind direction shaft 24. The slider 241 is disposed within the hollow structure and can move along the axial direction of the central rod 32 inside the hollow structure, driving the wind direction shaft 24 to move.

[0036] Furthermore, in order to solve the problem of low-frequency large-amplitude oscillation of base 3 under strong winds, such as Figure 1 As shown, a oscillation damping ball 34 is provided below the center rod 32. The oscillation damping ball 34 is connected to the center rod 32 through the second spring 35. Through the extension and contraction of the second spring 35 and the inertial oscillation of the damping ball, the oscillation energy is consumed, the low-frequency oscillation of the entire device is suppressed, and the risk of overturning is further reduced.

[0037] Furthermore, in order to address the problem of overall structural shaking caused by ground vibration and wind load, such as Figure 6 As shown, a first vibration damping component 33 is provided on the support plate 31. The wind speed unit 2 passes through the center of the first vibration damping component 33 and the support plate 31 and is connected to the central rod 32. Specifically, the wind direction rod 22 of the wind speed unit 2 passes through the center of the first vibration damping component 33 and the support plate 31. The first vibration damping component 33 provides primary vibration isolation for the wind direction rod 22, reducing the transmission of vibrations from the bottom and sides, and improving the static stability of the entire device.

[0038] Furthermore, in order to solve the problem of periodic swaying of the device under the continuous action of gusts, the first vibration damping component 33 in this embodiment includes an airbag component 331. The airbag component 331 includes multiple airbags, which are evenly distributed around the central axis of the first vibration damping component 33. The compression deformation of the airbags provides omnidirectional compliant support to the wind direction bar 22, thereby mitigating the impact of wind loads from all directions and keeping the device stable as a whole.

[0039] Furthermore, to address the issue of excessive stiffness or insufficient cushioning stroke in single-layer airbags under pressure, this embodiment employs an inner and outer double-layer airbag structure. Specifically, as shown... Figure 7 As shown, the airbag includes an inner airbag 3311 and an outer airbag 3312. The outer airbag 3312 is disposed outside the inner airbag 3311, and the inner airbag 3311 and the outer airbag 3312 are arranged coaxially. The wind vane 22 of the wind speed unit 2 passes through the middle of the inner airbag 3311 and is supported by the inner airbag 3311. The outer airbag 3312 serves as an auxiliary buffer, increasing the effective buffer volume and deformation stroke, improving vibration isolation flexibility, and enabling the device to have a longer buffer path and a gentler vibration reduction response when subjected to sudden wind impacts.

[0040] like Figure 8 and Figure 9 As shown, the airbag in this embodiment also includes a damping valve assembly 332, which is disposed between the outer airbag 3312 and the inner airbag 3311. The interior of the inner airbag 3311 and the interior of the outer airbag 3312 are connected through the damping valve assembly 332. The damping valve in this embodiment is a bidirectional damping valve.

[0041] like Figure 9 As shown, the damping valve assembly 332 includes a housing and a damping valve. The housing 3321 has an arc-shaped structure. The outer surface of the housing 3321 is fitted with an outer airbag 3312, and the inner surface of the housing 3321 is fitted with an inner airbag 3311. The damping valve includes a first damping valve and a second damping valve. The housing 3321 is provided with a first through hole and a second through hole penetrating the inner and outer surfaces. The first damping valve is arranged in the first through hole along the central axis of the first through hole, and the second damping valve is arranged in the second through hole along the central axis of the second through hole.

[0042] like Figure 10 As shown, both the first damping valve and the second damping valve include a baffle 3322, a vent plate 3323, and a first spring 3324. The first spring 3324 connects the baffle 3322 and the vent plate 3323. The baffle 3322 has a T-shaped structure, which includes a first end and a second end. The first end is positioned away from the direction of the first spring 3324. The diameter of the first end is smaller than the diameter of the second end, and the diameter of the second end is the same as the diameter of the baffle 3322.

[0043] Preferably, the diameter of the first through hole is the same as the diameter of the second through hole, the diameter of the first end is smaller than the diameter of the first and second through holes, and the diameter of the second end is larger than the diameter of the first and second through holes. In use, the first end extends into the first / second through hole, and a gap is provided between it and the sidewall of the first / second through hole.

[0044] It should be noted that the vent plate 3323 in the first through-hole is positioned towards the outer airbag 3312, and the vent plate 3323 in the second through-hole is positioned towards the inner airbag 3311. When the pressure in the inner airbag 3311 is greater than that in the outer airbag 3312, the gas inside the inner airbag 3311 enters the interior of the housing 3321 through the vent plate 3323 in the second damping valve, and then enters the outer airbag 3312 through the vent plate 3323 in the first damping valve. When the pressure in the outer airbag 3312 is greater than that in the inner airbag 3311, the gas inside the outer airbag 3312 enters the interior of the housing 3321 through the vent plate 3323 in the first damping valve, and then enters the inner airbag 3311 through the vent plate 3323 in the second damping valve. When the pressures of the inner airbag 3311 and the outer airbag 3312 are balanced, the small end of the baffle 3322 of the first damping valve enters the first through-hole, and the large end blocks the first through-hole. At the same time, the small end of the baffle 3322 of the second damping valve enters the second through hole, and the large end blocks the second through hole, so that the airbag is in a sealed state during static equilibrium, reducing the impact of air leakage on the support stiffness.

[0045] Furthermore, in order to solve the problem of damping mismatch caused by excessively fast or slow gas flow when the inner and outer airbags are compressed, this embodiment sets an arc-shaped shell 3321 with a bidirectional damping valve between the inner and outer airbags. By using the unidirectional conduction characteristics of the first and second damping valves, the flow rate of gas between the inner and outer airbags is controlled to achieve adjustable damping force, thereby providing appropriate damping during the compression and rebound of the airbags, reducing the resonance and residual vibration of the entire device during windward swaying, and improving dynamic stability.

[0046] Furthermore, such as Figure 11 As shown, the base 3 also includes support legs 37. Support legs 37 are circumferentially positioned below the support plate 31 and are inclined to increase the support span and ground contact area, improving the device's anti-overturning ability and grip on rough terrain, and reducing the risk of the device tipping over due to ground subsidence or gusts of wind. Exemplarily, the support legs 37 are connected to the support plate 31 via U-shaped lugs. A pivot is provided in the U-shaped lugs, allowing the support legs 37 to rotate around the pivot, maintaining a suitable tilt angle with the support plate 31. The pivot has a damping structure. The damping structure of the pivot is prior art and will not be described further here.

[0047] like Figure 1 As shown, the end of the outrigger 37 is provided with a support plate 38, which is fixedly connected to the ground by bolts.

[0048] Furthermore, in order to transmit the vibration of the central rod 32 to the base 3 and decompose the vibration, such as... Figure 11As shown, in this embodiment, a second vibration damping component 36 is provided at the lower part of the support plate 31. The second vibration damping component 36 includes a connecting plate 361, a telescopic chain link 362, and a conical vibration damper 363. The connecting plate 361 is fixed to the central rod 32 by threads, and the telescopic chain link 362 connects the connecting plate 361 and the conical vibration damper 363. In this embodiment, the conical vibration damper 363 in the second vibration damping component 36 isolates and absorbs vibrations transmitted to the base 3 in multiple directions and at multiple frequencies, improving the device's ability to suppress vibration sources of different frequencies. At the same time, the telescopic chain link 362 can adapt to ground deformation and vibration displacement within a certain range, further isolating irregular excitations from the bottom.

[0049] The second vibration damping assembly 36 is provided with multiple conical vibration dampers 363, which are evenly distributed circumferentially around the axis of the central rod 32. The small conical end of the conical vibration damper 363 is axially oriented towards the axis of the central rod 32.

[0050] like Figure 12 and Figure 13 As shown, the conical vibration damper 363 includes a conical shell 3631 and a frame 3632, with the frame 3632 disposed inside the conical shell 3631. The conical shell 3631 is made of rubber, and the frame 3632 is made of metal, to achieve multi-frequency vibration damping.

[0051] The frame 3632 is a conical stack, with the small end of the conical stack corresponding to the small end of the conical shell 3631; the conical stack is distributed perpendicular to the central axis of the conical damper 363. The conical stack has a corrugated structure.

[0052] This embodiment employs a conical rubber component with a built-in corrugated metal skeleton 3632. By utilizing the synergistic effect of the viscoelasticity of the rubber and the stiffness of the metal skeleton 3632, a multi-interface damping dissipation path is provided through the corrugated laminated structure, which can segmentally reduce vibrations of different frequencies. It has excellent dissipation effect, especially for mid-to-high frequency vibrations. At the same time, the metal skeleton 3632 enhances the structural strength and creep resistance of the conical vibration damper 363, extends the service life of the vibration damper, and improves the consistency of vibration damping.

[0053] Furthermore, it also includes a controller, which is electrically connected to the rotating motor 12 and the wind vane 21, for receiving signals from the wind vane 21 and sending rotation commands to the rotating motor 12.

[0054] In summary, this embodiment integrates the meteorological wind speed device with the UAV link equipment, reducing the assembly time and carrying burden for ground personnel. By controlling the link 11 to rotate to the direction of minimum windward area in real time through the wind vane 21, and combining the synergistic effect of the ring-shaped anti-sway structure of the spring 14, the double-layer airbag damping vibration reduction system, the wide-frequency vibration isolation of the conical vibration damper 363, and the sway damping ball 34, the risk of overturning and vibration interference in strong wind and gust environments is reduced, ensuring the continuity and stability of the link 11 signal transmission. It is especially suitable for unmanned helicopter testing scenarios under harsh climatic conditions such as deserts and Gobi.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
