[0044] Referring to Figures 1 to 6 , the embodiment provides a compact weather station, comprising a support base 1, a wind speed detection device 2 and a wind direction detection device 3.

[0045] The wind speed detection device 2 comprises a first shaft 21, a wind rotating body 22, a wind speed sensor 23 and a wind speed circuit board 24. The first shaft 21 has a hollow area passing through from top to bottom. The first shaft 21 is arranged on the support base 1. The wind rotating body 22 is arranged on the outside of the first shaft 21 and can rotate relative to the first shaft 21. The wind speed sensor 23 is used to convert the rotating speed of the wind rotating body 22 into an electric signal. The wind speed circuit board 24 is used to convert the electric signal detected by the wind speed sensor 23 into a corresponding wind speed value.

[0046] The wind direction detection device 3 comprises a second shaft 31, a wind vane 32, a wind direction sensor 34 and a wind direction circuit board 35. The second shaft 31 passes through the hollow area of the first shaft 21 from top to bottom. The second shaft 31 can rotate relative to the first shaft 21. The wind vane 32 is arranged above the wind rotating body 22 and on the upper end of the first shaft 21. The wind vane 32 can rotate following the rotation of the second shaft 31. The wind direction sensor 34 is used to convert the mechanical rotation of the wind vane 32 into an electric signal. The wind direction circuit board 35 is used to convert the electric signal detected by the wind direction sensor 34 into a corresponding wind direction.

[0047] The first shaft 21 is relatively static with the support base 1. The wind rotating body 22 can rotate on the first shaft 21 under the driving of the wind. The first shaft 21 has a hollow structure, and the hollow area is used for the second shaft 31 to pass through from top to bottom. The second shaft 31 can rotate freely relative to the first shaft 21, ensuring that the wind vane 32 can rotate following the change of the wind direction. Through the above design, the wind vane 32 can be stably supported above the wind rotating body 22, ensuring that the measured wind speed and wind direction data are very close to the same position, improving the consistency and accuracy of the data. Such layout is more compact, saving space.

[0048] When the wind blows through the weather station, the wind rotating body 22 starts to rotate due to the action of the wind force. The wind speed sensor 23 detects the rotating speed of the wind rotating body 22 and converts this physical movement into an electric signal. The wind speed circuit board 24 processes these electric signals, calculates the current wind speed value, and outputs the result through the display screen or other ways. Similarly affected by the wind force, the wind vane 32 will rotate following the change of the wind direction. The wind direction sensor 34 detects the rotating angle of the wind vane 32 and converts it into an electric signal. The wind direction circuit board 35 processes these electric signals, determines the current wind direction, and outputs the corresponding wind direction information.

[0049] Referring to Figure 1 , Figure 2 , Figure 4 andFigure 6 In the present embodiment, the wind direction detecting device 3 further comprises a support cylinder 36, which is located between the wind rotating body 22 and the wind vane 32, and has a slot 361 passing through the support cylinder 36 from top to bottom, the support cylinder 36 is sleeved on the outside of the first shaft 21 through the slot 361, and the second bearing 33 is arranged at the slot 361, the second bearing 33 is located above the first shaft 21 and is sleeved on the outside of the second shaft 31, so as to enable the second shaft 31 to rotate relative to the first shaft 21.

[0050] The support cylinder 36 can be a hollow cylindrical or circular truncated cone structure, and the internal space of the support cylinder 36 allows the first shaft 21 to pass through. The internal space of the support cylinder 36 is provided with the slot 361 passing through the support cylinder 36 from top to bottom, and the slot 361 is tightly sleeved on the outside of the first shaft 21, so that the first shaft 21 serves to fix the support cylinder 36, and there is no relative movement between the support cylinder 36 and the first shaft 21. The first shaft 21 is below the second bearing 33, and the second shaft 31 extends out of the upper side of the first shaft 21, and the extended part is supported by the second bearing 33, so that the second shaft 31 can rotate by means of the second bearing 33, and the rotation of the wind vane 32 is smooth. In this way, the support cylinder 36 is connected with the first shaft 21 through the slot 361 in the inside of the support cylinder 36, so as to ensure that the wind vane 32 can be stably installed above the support cylinder 36, and the support cylinder 36 can be used as a protective shell, so that the whole device looks more beautiful.

[0051] In some embodiments, the second bearing 33 does not need to rely on the support cylinder 36, and the second bearing 33 can be arranged between the first shaft 21 and the second shaft 31.

[0052] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 In the present embodiment, the upper side of the support cylinder 36 has a second annular structure 364 protruding for waterproofing, and the second annular structure 364 is designed to protrude from the upper surface of the support cylinder 36, forming a physical barrier that effectively blocks rainwater or other liquids from the outside.

[0053] Please refer to Figure 6In this embodiment, the second annular structure 364 includes a second inner annular structure 3641 and a second outer annular structure 3642. The second inner annular structure 3641 is around the center notch 361 and surrounds the second shaft 31, and can present a concentric circle structure to prevent rain or other liquid from flowing down along the second shaft 31. The second outer annular structure 3642 is outside the second inner annular structure 3641 and surrounds the second inner annular structure 3641 to prevent rain or other liquid from flowing into the second inner annular structure 3641. Preferably, the second outer annular structure 3642 has a notch 3643 that can extend to the upper surface of the support cylinder 36 to allow liquid between the second inner annular structure 3641 and the second outer annular structure 3642 to flow out.

[0054] Referring to Figure 6 In this embodiment, the first shaft 21 and the support cylinder 36 are fastened together by the first bolt 362, which is parallel to the radial direction of the first shaft 21 and the support cylinder 36.

[0055] Holes are pre-drilled in the first shaft 21 and the support cylinder 36, and the positions of the holes are aligned. One or two of the holes have internal threads, so that the first bolt 362 can be locked in place. The positions of the first bolt 362 and the first bolt 363 are as shown in Figure 3 By radial fastening, the secure connection between the first shaft 21 and the support cylinder 36 is ensured, preventing relative displacement or loosening between the two, and enhancing the mechanical stability of the overall device.

[0056] Referring to Figure 1 , Figure 2 and Figure 4 In this embodiment, the weather station also includes a waterproof cover 25. The support cylinder 36 has a gap with the wind rotating body 22, and the waterproof cover 25 is detachably connected to the upper side of the wind rotating body 22. The waterproof cover 25 is located in the support cylinder 36 and can be passed through by the first shaft 21.

[0057] Since the wind rotating body 22 can rotate relative to the first shaft 21, the support cylinder 36 has a gap with it to avoid friction. However, the gap is prone to intrusion of external rain or other liquid into the interior, so the waterproof cover 25 can form a physical barrier to effectively block external rain or other liquid. The internal space of the support cylinder 36 is sufficient to accommodate the waterproof cover 25, maintaining the compactness of the overall volume.

[0058] Referring to Figure 5 In this embodiment, the upper side of the wind rotating body 22 has a limiting groove 221, and the waterproof cover 25 is arranged in the limiting groove 221. A threaded hole 222 is provided in the limiting groove 221, and the waterproof cover 25 is connected to the threaded hole 222 by a second bolt.

[0059] A limiting groove 221 is designed on the upper side of the wind rotating body 22, which is matched in shape and size with the lower part of the waterproof cover 25, ensuring that the waterproof cover 25 can be accurately embedded and positioned. The user uses the second bolt to connect through the hole 251 on the waterproof cover 25 and the screw hole 222 in the limiting groove 221, ensuring that the waterproof cover 25 is firmly fixed on the wind rotating body 22.

[0060] In the foregoing embodiments, the waterproof cover 25 and the wind rotating body 22 are detachably connected by bolts. The detachable connection mode allows users to clean or replace it when needed, simplifying the maintenance process. In some alternative embodiments, this detachable connection mode can be achieved by using a buckle connection or a magnetic attraction connection.

[0061] Please refer to Figure 5 In this embodiment, the waterproof cover 25 is convex cylindrical, which can gradually drain the liquid downward to the outside.

[0062] Please refer to Figure 5 In this embodiment, the upper side of the wind rotating body 22 has a convex first annular structure 223 for waterproofing, which is located inside the waterproof cover 25. The inner circle of the first annular structure 223 can pass through the second shaft 31, which is relatively high and can form a physical barrier, effectively blocking the rain or other liquids from the outside. Preferably, the first bearing 26 can be installed in the first annular structure 223.

[0063] Please refer to Figure 1 and Figure 3 In this embodiment, the wind speed sensor 23 includes a wind speed Hall sensor connected to the wind speed circuit board 24, which is installed in the support seat 1 through the mounting seat 4 and located directly below the wind rotating body 22. The wind speed circuit board 24 is located on the upper side of the mounting seat 4, and the wind rotating body 22 is provided with a wind speed magnet 231 adapted to the wind speed Hall sensor. When the wind blows the wind rotating body 22, the wind speed magnet 231 rotates with it, causing a change in the magnetic field. The wind speed Hall sensor detects these changes in the magnetic field and converts them into electrical signals. The wind speed circuit board 24 processes these electrical signals, calculates the wind speed value, and displays or transmits the result to other systems.

[0064] Please refer to Figure 2 Preferably, the wind speed magnet 231 is cylindrical and can be embedded in the slotted 224 inside the wind rotating body 22.

[0065] Please refer to Figure 1 and Figure 3In the embodiment, the upper side of the mounting seat 4 is provided with a protruding slot 41, and the wind speed circuit board 24 is inserted into the slot 41. The slot 41 simplifies the installation process of the wind speed circuit board 24, so that the circuit board can be easily inserted, the complicated calibration steps are reduced, and the assembly efficiency is improved. It should be noted that the circuit board can be fixed on the mounting seat 4 by bolts, for example, the wind direction circuit board 35 is fastened on the lower side of the mounting seat 4 by bolts.

[0066] Referring to Figure 1 , Figure 3 and Figure 4 In the embodiment, the wind direction sensor 34 includes two wind direction Hall sensors, which are connected to the wind direction circuit board 35 respectively, the second shaft 31 extends into the support seat 1, and the lower side of the second shaft 31 is provided with a wind direction magnet 341 matched with the wind direction Hall sensor. The wind direction circuit board 35 is installed in the support seat 1 through the mounting seat 4, and is located on the lower side of the mounting seat 4. When the wind blows the wind vane 32, the wind direction magnet 341 rotates and changes the magnetic field. The two wind direction Hall sensors detect these changes in the magnetic field and convert them into electrical signals. The wind direction circuit board 35 processes these electrical signals, calculates the wind direction value, and displays or transmits the result to other systems.

[0067] Referring to Figure 1 , Figure 3 and Figure 4 Preferably, the wind direction magnet 341 is a ring magnet, and the two wind direction Hall sensors are linear Hall sensors. When the included angle between the two wind direction Hall sensors is 60 degrees or 90 degrees, the accuracy is relatively better, and the voltage-angle is relatively stable when the ring magnet is in the same plane. When the N and S poles of the ring magnet are distributed on the left and right sides, as the wind vane 32 rotates, the magnet also rotates with the wind vane 32. When the S pole is aligned with the wind direction Hall sensor, the voltage is the highest. When the wind vane rotates one circle, the magnetic field S pole gradually changes to the N pole, and then the N pole gradually changes to the S pole. This causes the voltage to gradually change from high to low and then from low to high, forming a whole circle of voltage curve, which ensures low power consumption and accuracy.

[0068] Referring to Figure 1 and Figure 3 In the embodiment, the wind speed circuit board 24 and the wind direction circuit board 35 are located on the upper and lower sides of the mounting seat 4, the wind speed circuit board 24 is located on the upper side and close to the wind rotating body 22, and the wind direction circuit board 35 is located on the lower side and close to the part where the second shaft 31 extends out of the lower side of the first shaft 21. In addition, the wind direction circuit board 35 and the wind speed circuit board 24 both have through holes for the second shaft 31 to pass through. Such a design helps to optimize the internal space layout, making the entire device more compact and reducing unnecessary volume occupation.

[0069] In some embodiments, the wind speed sensor 23 can employ a photoelectric encoder or an ultrasonic sensor, and the wind direction sensor 34 can employ a potentiometer sensor or a photoelectric encoder.

[0070] Please refer to Figure 1 , Figure 2 and Figure 4 In this embodiment, the wind rotating body 22 is a wind cup, which is usually formed by three or four semi-spherical cup bodies, and has the advantages of large wind measurement range, high strength, corrosion resistance, etc. In some embodiments, the wind rotating body 22 can be a propeller blade.

[0071] Please refer to Figure 1 and Figure 4 In this embodiment, the first bearing 26 is arranged between the wind rotating body 22 and the first shaft 21 to ensure that the wind rotating body 22 can rotate freely. There can be multiple first bearings 26, which are distributed along the axial direction of the first shaft 21. The multiple first bearings 26 provide multi-point support, so that the wind rotating body 22 can rotate smoothly in the entire length range, and reduce the deviation or uneven wear that can be caused by a single bearing.

[0072] Please refer to Figure 1 In this embodiment, the support base 1 includes a base 11 and a connecting cylinder 12 protruding from the upper side of the base 11. The base 11 and the connecting cylinder 12 form a cavity inside to accommodate the first shaft 21, the second shaft 31 and the mounting seat 4. The mounting seat 4 can be fixed in the cavity of the connecting cylinder 12 by bolts.

[0073] Please refer to Figure 1 , Figure 3 and Figure 4 In this embodiment, the mounting seat 4 is provided with a third bearing 37, and the second shaft 31 penetrates the mounting seat 4 and is sleeved on the third bearing 37. The third bearing 37 can support the rotation of the second shaft 31.

[0074] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of the present application, they should not limit the patent protection scope of the present application. Any equivalent structure or equivalent flow replacement or modification based on the essential concept of the present application, using the content described in the specification and drawings of the present application, and directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of the present application.
