Description

Technical Field

[0001] This application relates to the field of meteorological information collection, and in particular to a meteorological observation device. Background Technology

[0002] Meteorological observation devices are essential tools for collecting, measuring, and recording various meteorological elements, and are of paramount importance to meteorological research, weather forecasting, agriculture, transportation, and other fields. Thermometers, hygrometers, barometers, anemometers, wind vanes, rain gauges, and solar radiometers are all examples of meteorological observation devices. In addition, commonly used meteorological observation devices include weather radar and meteorological satellites.

[0003] An anemometer is a common meteorological observation device used to monitor wind speed. Anemometers typically use a rotating shaft in conjunction with an arc-shaped wind receiving plate to measure wind speed. The rotating shaft and the arc-shaped wind receiving plate are connected by a connecting shaft. However, in order to make the anemometer rotate smoothly and to make the wind speed monitoring accurate, the connecting shaft is usually made of a thin hollow shaft. When the angle between the wind speed and the rotating shaft is too large and the wind speed is high, it will cause the connecting shaft to break. Utility Model Content

[0004] This application provides a meteorological observation device to solve the problem that the connecting shaft between the rotating shaft and the arc-shaped wind receiving plate in a wind speed sensor is prone to breakage.

[0005] This application provides a meteorological observation device, including a meteorological observation frame, an electrical component box, a wind speed sensor, a mounting tube, a rotating shaft, a rotating body, and wind-sensing blades. The electrical component box is fixedly mounted on the observation frame. The wind speed sensor is disposed inside the electrical component box. The mounting tube is disposed on the side wall of the electrical component box away from the meteorological observation frame and extends in a direction away from the meteorological observation frame, and the mounting tube communicates with the inner cavity of the electrical component box. The rotating shaft is rotatably disposed inside the mounting tube, and one end of the rotating shaft passes through the side wall of the electrical component box and is connected to the wind speed sensor. The rotating body is disposed on the mounting tube, and a gap is provided between the rotating body and the mounting tube. The rotating body is fixedly connected to the rotating shaft. Multiple wind-sensing blades are disposed evenly on the outer ring wall of the rotating body around the axis of the rotating shaft.

[0006] The meteorological observation frame, electrical component box, wind speed sensor, and mounting pipe in this application serve to support the rotating shaft and detect its rotational speed to determine wind speed. The rotating body is mounted on the mounting pipe and fixedly connected to the rotating shaft. The wind-sensing blades are located outside the rotating body. When the wind blows, the wind-sensing blades drive the rotating shaft to rotate, thereby allowing the wind speed sensor to measure the wind speed. In this design, the connection area between the wind-sensing blades and the rotating body is larger, resulting in a stronger connection between the wind-sensing blades and the rotating shaft. Simultaneously, the rotating body itself is less prone to breakage, reducing the possibility of breakage between the rotating shaft and the wind-sensing blades.

[0007] In some embodiments of this application, the wind-sensing blades are arc-shaped and have arc-shaped recesses, with all the arc-shaped recesses of the wind-sensing blades distributed in the same direction around the axis of rotation. The annular recesses can increase the impact force of wind on the wind-sensing blades, making the wind-sensing blades more sensitive to wind and facilitating wind speed detection.

[0008] In some embodiments of this application, the rotating shaft and the rotating body are coaxially arranged, and the rotating shaft and the mounting tube are coaxially arranged. The coaxial arrangement can make the rotation of the rotating shaft smoother.

[0009] In some embodiments of this application, the meteorological observation device further includes a first bearing, through which the rotating shaft and the mounting tube are connected. The first bearing connects the rotating shaft and the mounting tube, which can make the position of the rotating shaft more stable and reduce friction between the rotating shaft and the mounting tube that may occur during rotation.

[0010] In some embodiments of this application, multiple first bearings are provided, and the multiple first bearings are spaced apart along the axial direction of the rotating shaft. Multiple first bearings can further stabilize the position of the rotating shaft, thereby making the shaft rotate more smoothly and the wind speed detection more accurate.

[0011] In some embodiments of this application, the meteorological observation device further includes a connecting body disposed between the rotating body and the rotating shaft, and the connecting body is fixedly connected to the rotating body and the rotating shaft. The connecting body can facilitate the fixed connection between the rotating body and the rotating shaft, and improve the connection strength between the rotating body and the rotating shaft.

[0012] In some embodiments of this application, the meteorological observation device further includes a cover, which is disposed at the end of the rotating body away from the mounting tube, and the cover is sealed to the rotating body. The cover can protect the rotating shaft and the connecting body, preventing direct wind from causing instability in the connection between the rotating body and the rotating shaft.

[0013] In some embodiments of this application, the meteorological observation device further includes a cap, which is disposed on the side of the rotating body away from the mounting tube. A rotating shaft passes through the rotating body and extends into the cap, and the rotating shaft is rotatably connected to the cap. A gap is provided between the rotating body and the cap. The cap can serve a similar function to the cover, protecting the rotating body and the mounting tube through a split structure.

[0014] In some embodiments of this application, the meteorological observation device further includes a second bearing, through which the rotating shaft and the cap are rotatably connected. The second bearing allows relative rotation between the rotating shaft and the cap, preventing the cap from affecting the rotation of the rotating shaft due to force, and also preventing the cap from being installed unstablely.

[0025] Meteorological observation devices are essential tools for collecting, measuring, and recording various meteorological elements, and are of paramount importance to meteorological research, weather forecasting, agriculture, transportation, and other fields. Thermometers, hygrometers, barometers, anemometers, wind vanes, rain gauges, and solar radiometers are all examples of meteorological observation devices. In addition, commonly used meteorological observation devices include weather radar and meteorological satellites.

[0026] An anemometer is a common meteorological observation device used to monitor wind speed. Anemometers typically use a rotating shaft in conjunction with an arc-shaped wind receiving plate to measure wind speed. The rotating shaft and the arc-shaped wind receiving plate are connected by a connecting shaft. However, in order to make the anemometer rotate smoothly and to make the wind speed monitoring accurate, the connecting shaft is usually made of a thin hollow shaft. When the angle between the wind speed and the rotating shaft is too large and the wind speed is high, it will cause the connecting shaft to break.

[0027] Therefore, please refer to Figure 1 This application provides a meteorological observation device, including a meteorological observation frame 1, an electrical component box 2, a wind speed sensor 3, a mounting tube 4, a rotating shaft 5, a rotating body 6, and wind-sensing blades 7.

[0028] Please refer to Figure 1 The electrical component box 2 is fixedly mounted on the observation frame. The observation frame can be a conventional support, column, or tripod; the electrical component box 2 and the observation frame can be connected by bolts or clips; both the observation frame and the electrical component box 2 can be made of metal or non-metal materials, and the materials can be the same or different.

[0029] Please refer to Figure 1The wind speed sensor 3 is installed inside the electrical component box 2. The wind speed sensor 3 can be a conventional structure that measures wind speed by the rotation speed of the rotating shaft 5; at the same time, the wind speed sensor 3 and the rotating shaft 5 can be directly plugged in, or the wind speed can be measured through a transmission component or a corresponding tachometer.

[0030] Please refer to Figure 1 Meanwhile, the electrical component box 2 can also be equipped with a power supply, controller and other components to ensure the normal operation of the wind speed sensor 3.

[0031] Please refer to Figure 1 The mounting pipe 4 is located on the side wall of the electrical component box 2 away from the meteorological observation frame 1 and extends in a direction away from the meteorological observation frame 1. The mounting pipe 4 is connected to the inner cavity of the electrical component box 2. The mounting pipe 4 can be a round pipe, and its material can be metal or non-metal. The mounting pipe 4 and the electrical component box 2 can be welded, bonded, or integrally formed.

[0032] Please refer to Figure 1 The rotating shaft 5 is rotatably mounted inside the mounting tube 4, with one end of the rotating shaft 5 passing through the side wall of the electrical component box 2 and connected to the wind speed sensor 3. The rotating shaft 5 can be made of metal or non-metal, and can be a cylindrical shaft, which can be hollow or solid.

[0033] Please refer to Figure 1 The rotating body 6 is mounted on the mounting tube 4, with a gap between the rotating body 6 and the mounting tube 4. The rotating body 6 is fixedly connected to the rotating shaft 5. The rotating body 6 can be a ring or other structure with an inner cavity, which can be circular or square. The rotating body 6 can be made of metal or non-metal.

[0034] Please refer to Figure 1 The gap between the rotating body 6 and the mounting tube 4 can be between 1mm and 2mm, just enough to allow it to rotate. The outer diameter of the rotating body 6 can completely cover the mounting tube 4, and its inner diameter can be less than or equal to the inner diameter of the mounting tube 4. The sidewalls of the rotating body 6 opposite to the mounting tube 4 can be made with high-precision surfaces to avoid friction.

[0035] Please refer to Figure 1 Multiple wind-sensing blades 7 are provided, and the multiple wind-sensing blades 7 are evenly arranged on the outer ring wall of the rotating body 6 around the axis of the rotating shaft 5. The wind-sensing blades 7 can be semi-circular or other shapes. The wind-sensing blades can be integrally formed with the rotating body 6, or they can be bonded or bolted to the rotating body 6.

[0036] Please refer to Figure 1In this application, the meteorological observation frame 1, electrical component box 2, wind speed sensor 3, and mounting pipe 4 serve to support the rotating shaft 5 and detect the rotational speed of the rotating shaft 5 to determine the wind speed. The rotating body 6 is mounted on the mounting pipe 4 and fixedly connected to the rotating shaft 5. The wind-sensing blade 7 is located outside the rotating body 6. When the wind blows, the wind-sensing blade 7 can drive the rotating shaft 5 to rotate, thereby allowing the wind speed sensor 3 to measure the wind speed. In this design, the connection area between the wind-sensing blade 7 and the rotating body 6 is larger, resulting in a stronger connection between the wind-sensing blade 7 and the rotating shaft 5. At the same time, the rotating body 6 itself is less prone to breakage, reducing the possibility of breakage between the rotating shaft 5 and the wind-sensing blade 7.

[0037] Please refer to Figure 2 In some examples, the wind-sensing blade 7 is arc-shaped and has an arc-shaped recess 71. The arc-shaped recesses 71 of all wind-sensing blades 7 are distributed in the same direction around the circumference of the axis of rotation 5. The annular recesses can increase the impact force of wind on the wind-sensing blade 7, making the wind-sensing blade 7 more sensitive to wind and helping to detect wind speed.

[0038] Please refer to Figure 2 In some examples, the wind-sensing blade 7 can be an arc-shaped blade, such as a partially spherical surface or other arc surfaces, as long as it can better receive the wind and drive the rotating shaft 5 to rotate.

[0039] Please refer to Figure 2 In some examples, along the axial direction of the rotating shaft 5, the arc-shaped recesses 71 of multiple wind-sensing blades 7 can all be set clockwise or all be set counterclockwise.

[0040] Please return to the reference. Figure 1 In some examples, the rotating shaft 5 is coaxially arranged with the rotating body 6, and the rotating shaft 5 is coaxially arranged with the mounting tube 4. The coaxial arrangement allows the rotating shaft 5 to rotate more smoothly.

[0041] Please refer to Figure 1 In some examples, the pivot 5 can be a completely circular shaft, a stepped shaft, or other composite shaft, as long as it can rotate freely.

[0042] Please refer to Figure 1 In some examples, the inner wall of the mounting tube 4 can be cylindrical, and the rotating body 6 can be annular, so that the axes of the mounting tube 4, the rotating shaft 5 and the rotating body 6 are completely coincident.

[0043] Please refer to Figure 1 In some examples, the meteorological observation device also includes a first bearing 41, through which the rotating shaft 5 and the mounting tube 4 are connected. The first bearing 41 connects the rotating shaft 5 and the mounting tube 4, which can make the position of the rotating shaft 5 more stable and reduce the friction that may occur between the rotating shaft 5 and the mounting tube 4 when the rotating shaft 5 rotates.

[0044] Please refer to Figure 1 In some examples, the first bearing 41 can be a ball bearing, or it can be a roller bearing or other bearing.

[0045] Please refer to Figure 1 In some examples, multiple first bearings 41 are provided, and the multiple first bearings 41 are distributed at intervals along the axial direction of the rotating shaft 5. Multiple first bearings 41 can further stabilize the position of the rotating shaft 5, thereby making the rotation of the rotating shaft 5 smoother and the detection of wind speed more accurate.

[0046] Please refer to Figure 1 In some examples, the number of first bearings 41 can be 2 to 5, preferably two. The two first bearings 41 can be respectively located at one end of the rotating shaft 5 near the electrical component box 2 and at the other end of the rotating shaft 5 near the rotating body 6.

[0047] Please refer to Figure 1 In some examples, the first bearing 41 can be tightly connected to both the rotating body 6 and the mounting tube 4 to ensure stable installation of the first bearing 41. Simultaneously, corresponding steps can be provided on the inner wall of the mounting tube 4 and the outer ring wall of the rotating shaft 5 to facilitate the installation of the first bearing 41.

[0048] Please refer to Figure 1 In some examples, the meteorological observation device also includes a connector 61, which is disposed between the rotating body 6 and the rotating shaft 5, and is fixedly connected to both the rotating body 6 and the rotating shaft 5. The connector 61 can help to fix the rotating body 6 and the rotating shaft 5, and improve the connection strength between the rotating body 6 and the rotating shaft 5.

[0049] Please refer to Figure 1 In some examples, the connector 61 can be a column, and the number can be 3 to 8. The connector 61 can be fixedly connected to the rotating shaft 5 and the rotating body 6, for example, it can be integrally formed, or it can be welded, bonded or threaded.

[0050] Please refer to Figure 1 In some examples, the connector 61 is located inside the rotating body 6 to prevent it from being blown by the wind, and also to prevent the connector 61 from breaking due to the tangential force generated when the wind-sensing blade 7 is exposed to the wind, thereby improving the strength and stability of the rotating body 6 and the wind-sensing blade 7.

[0051] Please refer to Figure 1 In some examples, the meteorological observation device also includes a cover 62, which is located at the end of the rotating body 6 away from the mounting tube 4 and is sealed to the rotating body 6. The cover 62 can protect the rotating shaft 5 and the connecting body 61, preventing direct wind from causing instability in the connection between the rotating body 6 and the rotating shaft 5.

[0052] Please refer to Figure 1 In some examples, the cover 62 can be integrally formed with the rotating body 6, or the cover 62 can be snapped, glued or welded to the rotating body 6, which can also achieve the above effect.

[0053] Please refer to Figure 1 In some examples, the cover 62 can be adapted to the outer diameter of the rotating body 6, that is, the outer diameter of the cover 62 can be slightly larger than the diameter of the rotating body 6, or the maximum diameter of the cover 62 can be equal to or slightly smaller than the diameter of the rotating body 6.

[0054] Please refer to Figure 1 In some examples, the material of the cover 62 may be the same as that of the rotating body 6, or it may be a different material. The thickness of the cover 62 may be the same as the wall thickness of the rotating body 6, or it may be less than the wall thickness of the rotating body 6.

[0055] Please refer to Figure 3 In some examples, the meteorological observation device also includes a cap 8, which is located on the side of the rotating body 6 away from the mounting tube 4. A rotating shaft 5 passes through the rotating body 6 and extends into the cap 8. The rotating shaft 5 is rotatably connected to the cap 8, and a gap is provided between the rotating body 6 and the cap 8. The cap 8 can serve a similar function to the cover 62, protecting the rotating body 6 and the mounting tube 4 through a split structure.

[0056] Please refer to Figure 3 In some examples, the cap 8 can coexist with the cover 62. That is, when the cover 62 is provided on the rotating body 6, the rotating shaft 5 can not pass through the cover 62 and the cap 8 is not provided. When the cover 62 is not provided on the rotating body 6 so that the rotating body 6 can pass through vertically, the rotating shaft 5 can pass through the cover 62 and extend into the cap 8.

[0057] Please refer to Figure 3 In some examples, the cap 8 can be fitted with the outer diameter of the rotating body 6, so that the maximum diameter of the cap 8 is slightly larger than the diameter of the rotating body 6, or the maximum diameter of the cap 8 is equal to or slightly smaller than the diameter of the rotating body 6.

[0058] Please refer to Figure 3 In some examples, when the cap 8 is fixedly connected to the rotating shaft 5, a gap can be provided between the cap 8 and the rotating body 6 to reduce the rotational friction of the rotating body 6. The gap can be between 1mm and 3mm, preferably 1mm.

[0059] Please refer to Figure 3In some examples, the meteorological observation device also includes a second bearing 81, through which the rotating shaft 5 and the cap are rotatably connected. The second bearing 81 allows relative rotation between the rotating shaft 5 and the cap 8, preventing the cap 8 from affecting the rotation of the rotating shaft 5 due to force, and also preventing the cap 8 from being installed unstablely.

[0060] Please refer to Figure 3 In some examples, the second bearing 81 can be the same as the first bearing 41, both of which can be ball bearings; the size of the second bearing 81 can also be the same as the first bearing 41, and the inner ring of the second bearing 81 can be tightly connected to the shaft 5 and the cap of the outer ring of the second bearing 81.

[0061] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0062] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto.
