Description

Technical Field

[0001] This application relates to the field of meteorological monitoring technology, and in particular to a wind speed and direction monitoring device for meteorological services. Background Technology

[0002] In the field of meteorological services, accurate acquisition of wind speed and direction data is fundamental for accurate weather forecasting, in-depth meteorological research, and ensuring agricultural production, aviation, and maritime safety. Cup-type anemometers typically consist of a cup, a rotating shaft, and a sensing element. The cup drives the shaft to rotate, and the sensing element detects this rotation and converts it into wind speed data.

[0003] To reduce the impact of the device housing on the wind cup's wind-sensing ability, the length of the shaft is usually set to be several times the size of the wind cup. At the same time, to increase the strength of the shaft and reduce its weight, it is usually made of solid high-strength aluminum alloy.

[0004] Although aluminum alloys have a lower density and are lighter than metals such as carbon steel, and the shaft reduces rotational friction through an interference fit bearing, its relatively long length results in a larger moment of inertia. When a sudden increase in wind speed occurs, the wind cup connected to the long shaft cannot quickly accelerate the shaft to the corresponding wind speed, leading to delays and inaccuracies in the monitoring data. Utility Model Content

[0005] This application provides a wind speed and direction monitoring device for meteorological services, which is used to improve the accuracy of wind speed monitoring data in wind speed phenomena such as gusts where wind speed suddenly increases.

[0006] This application provides a wind speed and direction monitoring device for meteorological services, including a main housing, a power supply and control components, an auxiliary housing, a sensing element, a sleeve, a rotating shaft, and wind cups. The power supply and control components are disposed inside the main housing. The auxiliary housing is disposed above the main housing and is fixedly connected to the main housing. The size of the auxiliary housing is smaller than that of the main housing. The sensing element is disposed inside the auxiliary housing and is electrically connected to the power supply and control components. The sleeve is disposed on the top of the auxiliary housing and is vertically arranged. The rotating shaft is rotatably disposed inside the sleeve. The bottom end of the rotating shaft penetrates through the top wall of the auxiliary housing and is connected to the sensing element. A gap is provided between the rotating shaft and the auxiliary housing, and the top end of the rotating shaft extends outside the sleeve. Multiple wind cups are disposed on the portion of the rotating shaft located outside the sleeve and are distributed circumferentially around the sleeve.

[0007] In this application, the power supply and control components and the sensing element are respectively housed in the main housing and the auxiliary housing. By separating the smaller part that needs to be connected to the rotating shaft outside the main housing, the phenomenon that the rotating shaft needs to extend into the main housing is avoided. By directly mounting the rotating shaft on the top of the auxiliary housing, transmission can be achieved through a shorter rotating shaft.

[0008] From a mechanical perspective, a longer shaft has a relatively larger moment of inertia under wind force. Therefore, a shorter shaft can reduce the moment of inertia, thereby reducing the resistance to wind-driven rotation of the wind cup and shaft, improving the sensitivity of the shaft, and thus improving the sensitivity of this wind speed and direction monitoring device. When faced with sudden increases in wind force or gusts, a more sensitive wind speed and direction monitoring device can make the monitoring data more accurate.

[0009] Meanwhile, the sensing element is small in size, so there is no need to set up a large auxiliary housing. The power supply and control components are larger in size, so they can be supported by a larger main housing. The auxiliary housing is small in size and has poor wind blocking effect. This avoids the fact that the auxiliary housing will block some of the wind and affect the accuracy of the wind speed and direction monitoring device, thus ensuring the accuracy of the monitoring results of the wind speed and direction monitoring device.

[0010] In some embodiments of this application, the top outer wall of the auxiliary housing is configured as a rounded surface. The rounded surface can further reduce the obstruction of wind, avoid affecting the wind cup's wind-sensing ability, and at the same time, the rounded shape can reduce wind resistance and improve stability.

[0011] In some embodiments of this application, the cross-section of the auxiliary housing is circular along the axis perpendicular to the sleeve. The fact that the cross-section of the auxiliary housing is preferably circular, i.e., the main body of the auxiliary housing is cylindrical, can further reduce wind resistance in all directions and improve the stability of the auxiliary housing.

[0012] In some embodiments of this application, the circular diameter of the auxiliary housing cross-section does not exceed 8 cm. A smaller size reduces the impact of the auxiliary housing on the wind cup's wind-sensing capability, ensuring the accuracy of the wind speed and direction monitoring results.

[0013] In some embodiments of this application, the wind speed and direction monitoring device for meteorological services further includes a support column, through which the main housing and the auxiliary housing are fixedly connected. The support column can relatively fix the main housing and the auxiliary housing, ensuring the stability of the auxiliary housing and the rotating shaft and sleeve located on the auxiliary housing.

[0014] In some embodiments of this application, multiple support columns are provided, spaced apart. Multiple support columns can further improve the connection strength between the main housing and the auxiliary housing.

[0015] In some embodiments of this application, the wind speed and direction monitoring device for meteorological services further includes a sleeve, which is fixedly disposed between the main housing and the auxiliary housing, connecting the main housing and the auxiliary housing, and located between multiple support columns; the power supply and control components are connected to the sensing element via wiring, which is arranged inside the sleeve. The sleeve facilitates the wiring arrangement and protects the wiring from wind and rain.

[0016] In some embodiments of this application, the shaft is a hollow aluminum alloy shaft. A hollow shaft can have a lighter mass, thereby further reducing the moment of inertia and further improving the sensitivity of the shaft, thus improving the sensitivity of the wind speed and direction monitoring device; the aluminum alloy material can provide high strength, and the shaft can be similar to a cantilever beam. By reducing the length of the shaft, its bending resistance can be enhanced, ensuring that the shaft has the strength to work stably for a long time.

[0017] In some embodiments of this application, the wind speed and direction monitoring device for meteorological services further includes a sealing ring disposed at the top of the sleeve, with a clearance fit between the sealing ring and the rotating shaft. The sealing ring can prevent water or insects from entering between the sleeve and the rotating shaft, thus protecting the sensing element. Attached Figure Description

[0025] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, when describing pipelines, the terms "connected" and "linked" as used in this application have the meaning of establishing electrical connection. The specific meaning needs to be understood in conjunction with the context.

[0026] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0027] In the field of meteorological services, accurate acquisition of wind speed and direction data is fundamental for accurate weather forecasting, in-depth meteorological research, and ensuring agricultural production, aviation, and maritime safety. Cup-type anemometers typically consist of a cup, a rotating shaft, and a sensing element. The cup drives the shaft to rotate, and the sensing element detects this rotation and converts it into wind speed data.

[0028] To reduce the impact of the device housing on the wind cup's wind-sensing ability, the length of the shaft is usually set to be several times the size of the wind cup. At the same time, to increase the strength of the shaft and reduce its weight, it is usually made of solid high-strength aluminum alloy.

[0029] Although aluminum alloys have a lower density and are lighter than metals such as carbon steel, and the shaft reduces rotational friction through an interference fit bearing, its relatively long length results in a larger moment of inertia. When a sudden increase in wind speed occurs, the wind cup connected to the long shaft cannot quickly accelerate the shaft to the corresponding wind speed, leading to delays and inaccuracies in the monitoring data.

[0030] At the same time, due to the long length of the shaft, multiple bearings will be installed on the outside of the shaft. The bearings and the shaft are tightly fitted, which places higher precision requirements on the shaft and other related structures, and increases the cost.

[0031] Therefore, please refer to Figure 1 and Figure 2 This application provides a wind speed and direction monitoring device for meteorological services, including a main housing 1, a power supply and control components 2, an auxiliary housing 3, a sensing element 4, a sleeve 5, a rotating shaft 6, and a wind cup 7.

[0032] Please refer to Figure 1 The main housing 1 can be designed in a streamlined shape, such as a cylinder or a frustum. This shape can effectively reduce wind resistance and reduce the impact of wind on the stability of the device. It also facilitates smooth airflow and reduces interference with wind speed and direction monitoring.

[0033] Please refer to Figure 1 The main housing 1 can be made of high-strength, corrosion-resistant, and insulating engineering plastics, such as an alloy of polycarbonate (PC) and acrylonitrile-butadiene-styrene copolymer (ABS), or it can be made of high-strength metals such as carbon steel, with rust-proof treatment. The main housing 1 has excellent impact resistance, able to withstand collisions that may occur in harsh outdoor environments, and also has good weather resistance, maintaining stable performance in long-term exposure to wind, sun, and rain, preventing the lifespan of the device from being affected by material aging.

[0034] Please refer to Figure 1 A support shaft 13 can be installed at the bottom of the main housing 1. The support shaft 13 is used to fix the entire device at the monitoring location. The support shaft 13 can be made of stainless steel to ensure sufficient strength and corrosion resistance. The main housing 1 is installed on top of the support shaft 13 and is firmly fixed with bolts or other connectors to ensure a stable and reliable connection.

[0035] Please refer to Figure 1 The power supply and control assembly 2 is disposed within the main housing 1. The power supply and control assembly 2 may include a power supply 21 and a control assembly 22, and may also include a communication structure or other components.

[0036] Please refer to Figure 1 The power supply 21 can consist of a solar panel, a battery, and a charging controller. The solar panel can be made of high-efficiency monocrystalline silicon material, thus having a high photoelectric conversion efficiency. Its shape is rectangular, and its size can be determined according to the actual power demand. Generally, the area is between 0.2 and 0.5 square meters, and it is laid on the top or side wall of the main casing 1.

[0037] Please refer to Figure 1 The storage battery can be a sealed lead-acid battery, which has good charge / discharge performance and a long service life. Its capacity is configured according to the power consumption of the device and local light conditions. The battery can be placed in a specially designed waterproof and dustproof box to protect it from environmental influences. Lithium batteries or other rechargeable batteries can also be used.

[0038] The charging controller is used to control the charging process of the solar panel to the battery, preventing overcharging and over-discharging. It is small in size and can be installed close to the battery for easy wiring connection.

[0039] Please refer to Figure 1 The solar panel is connected to the input terminal of the charging controller via a waterproof cable, and the output terminal of the charging controller is connected to the positive and negative terminals of the battery respectively.

[0040] Please refer to Figure 1 The control component 22 includes a central processing unit (CPU), memory chips, input / output interfaces, etc., all integrated on a printed circuit board (PCB). The CPU, as the core control unit, is connected to the memory chips and input / output interfaces via a data bus.

[0041] The data output terminals of the wind speed and wind direction sensors can be connected to the input interface of the control component 22 via shielded wiring to transmit the collected data to the CPU for processing. The data processing module and the wireless transmission module are connected to the output interface of the control component 22 to receive the data processed by the CPU and perform subsequent data processing and transmission operations.

[0042] Please refer to Figure 1 The central processing unit can be an STM32 series microcontroller, such as the STM32F407, which features high performance and low power consumption, meeting the device's requirements for data processing speed and real-time performance. The memory chip can be a K9F1G08U0M, providing reliable data storage. The charging controller can be an MPPT type controller, such as Morningstar's TS-45, which can effectively improve the charging efficiency of the solar panels.

[0043] Please refer to Figure 1 The auxiliary housing 3 is positioned above the main housing 1 and is fixedly connected to the main housing 1. The size of the auxiliary housing 3 is smaller than that of the main housing 1. The material of the auxiliary housing 3 can be the same as that of the main housing 1. The distance between the auxiliary housing 3 and the main housing 1 can be between 4 and 10 times the diameter of the rotating shaft 6. The dimensions of the auxiliary housing 3 refer to the side length and height of any side of the auxiliary housing 3. The auxiliary housing 3 can be located above the center of the main housing 1 or on one side of the main housing 1.

[0044] Please refer to Figure 1 and Figure 2The sensing element 4 is housed within the auxiliary housing 3 and is electrically connected to the power supply and control assembly 2. The sensing element 4 can be a magnetoelectric or photoelectric speed sensor. The magnetoelectric sensing element 4 can be 2-3 cm in diameter, 1-1.5 cm wide, and 1-1.5 cm high. The magnetoelectric speed sensor can detect the rotational speed of the shaft 6 using a built-in Hall effect sensor and convert it into corresponding data. Its model can be SS495A, or other types of magnetoelectric speed sensors can also be used.

[0045] Please refer to Figure 1 and Figure 2 The sleeve 5 is located on the top of the auxiliary housing 3 and is vertically positioned. The sleeve 5 can be made of the same material as the auxiliary housing 3, and the two can be fixedly connected. The axis of the sleeve 5 can be vertically positioned to facilitate the rotation of the shaft 6 inside the sleeve 5.

[0046] Please refer to Figure 1 and Figure 2 The rotating shaft 6 is rotatably mounted inside the sleeve 5. The bottom end of the rotating shaft 6 penetrates the top wall of the auxiliary housing 3 and is connected to the sensing element 4. A gap is provided between the rotating shaft 6 and the auxiliary housing 3, and the top end of the rotating shaft 6 extends outside the sleeve 5. The rotating shaft 6 can be made of aluminum alloy, specifically 7075 aluminum alloy, or other types of aluminum alloy.

[0047] Please refer to Figure 1 and Figure 2 The length of the rotating shaft 6 can be greater than the length of the wind cup 7, so that both ends of the rotating shaft 6 extend beyond the sleeve 5. The rotating shaft 6 and the sleeve 5 can be rotatably connected by bearings. Two bearings can be provided, located at both ends of the sleeve 5 respectively. The length of the sleeve 5 can be 4 to 8 times the diameter of the rotating shaft 6.

[0048] Please refer to Figure 1 and Figure 2 Multiple air cups 7 are configured and are located on the portion of the rotating shaft 6 outside the sleeve 5, with the multiple air cups 7 distributed at intervals around the circumference of the sleeve 5. The number of air cups 7 can be 3 to 6, and the multiple air cups 7 can be arranged at equal intervals around the circumference of the sleeve 5.

[0049] The wind cup 7 can be tightly connected to the rotating shaft 6 via the connecting assembly 71. The connecting assembly 71 may include two symmetrically arranged connecting clips, which may be made of high-strength, corrosion-resistant aluminum alloy. The inner side of each clip may be configured with a semi-circular groove that matches the mounting shaft of the wind cup 7. A soft rubber pad with a high coefficient of friction is embedded in the groove to ensure that the wind cup 7 is firmly installed while avoiding wear caused by hard contact.

[0050] The two clamping plates can be fastened with bolts and nuts. The bolts pass through the clamping plates and rubber gaskets. During the tightening of the nuts, the clamping plates will tightly hold the mounting shaft of the wind cup 7, forming a stable connection. One end of the rotating shaft 6 is machined with a mounting hole corresponding to the mounting shaft of the wind cup 7. After the mounting shaft of the wind cup 7 is inserted into the mounting hole of the rotating shaft 6, it is fixed by the aforementioned connecting component 71, ensuring a high degree of concentricity between the wind cup 7 and the rotating shaft 6. This prevents eccentric vibration during rotation and ensures the accuracy of wind speed monitoring.

[0051] Please refer to Figure 1 and Figure 2 In this application, the power supply and control components 2 and the sensing element 4 are respectively disposed in the main housing 1 and the auxiliary housing 3. By separating the smaller part that needs to be connected to the rotating shaft 6 outside the main housing 1, the phenomenon that the rotating shaft 6 needs to extend into the main housing 1 is avoided. By directly mounting the rotating shaft 6 on the top of the auxiliary housing 3, transmission can be achieved through a shorter rotating shaft 6.

[0052] From a mechanical perspective, a longer shaft 6 has a relatively larger moment of inertia under wind force. Therefore, a shorter shaft 6 can reduce the moment of inertia, thereby reducing the resistance to the wind-driven rotation of the wind cup 7 and shaft 6, improving the sensitivity of shaft 6, and thus enhancing the sensitivity of this wind speed and direction monitoring device. When faced with sudden increases in wind force or gusts, a more sensitive wind speed and direction monitoring device can make the monitoring data more accurate.

[0053] Meanwhile, the sensing element 4 is small in size, so there is no need to set up a large auxiliary housing 3. The power supply and control components 2 are large in size, so they can be supported by the large main housing 1. The auxiliary housing 3 is small in size and has a poor effect on blocking wind. This avoids the fact that some wind is blocked by the auxiliary housing 3 due to its position, which would affect the accuracy of the wind speed and direction monitoring device and ensure the accuracy of the monitoring results of the wind speed and direction monitoring device.

[0054] Please refer to Figure 2 In some examples, a transmission structure 41 can be configured between the rotating shaft 6 and the sensing element 4. The transmission structure 41 is responsible for transmitting the rotational motion of the wind cup 7 and the rotating shaft 6 to the sensing element 4. The transmission structure 41 can be a gear set or other transmission structures 41.

[0055] In some examples, the wind speed and direction monitoring device may also include a wind direction monitoring component, which is the core component for acquiring wind direction data.

[0056] The wind direction monitoring component can consist of a wind vane, an angle sensor, and a connecting shaft. The wind vane can be made of lightweight, high-strength materials, such as carbon fiber composites, ensuring that it can rotate sensitively in light breezes while possessing sufficient strength to withstand strong winds. The wind vane can be arrow-shaped.

[0057] The angle sensor can be a high-precision potentiometer-type angle sensor or a magnetoresistive angle sensor. Taking the potentiometer-type angle sensor as an example, its working principle is that the wind vane drives the connecting shaft to rotate. The connecting shaft is connected to the rotating shaft 6 of the potentiometer. When the wind vane rotates, the resistance value of the potentiometer changes accordingly. By measuring the change in resistance value, the rotation angle of the wind vane can be accurately calculated, and thus the wind direction can be determined.

[0058] Alternatively, a magnetoresistive angle sensor can be used. This sensor utilizes the magnetoresistive effect to measure the wind vane's rotation angle by detecting changes in the magnetic field, offering advantages such as high accuracy and strong anti-interference capabilities. The connecting shaft can be made of stainless steel, providing good rigidity and corrosion resistance. One end of the connecting shaft is firmly connected to the wind vane, while the other end is tightly fitted to the rotating shaft 6 of the angle sensor, ensuring that the wind vane's rotation is accurately transmitted to the angle sensor.

[0059] The wind direction detection component can be installed on the main housing 1 or located outside the sleeve 5.

[0060] Please refer to Figure 2 In some examples, the top outer wall of the auxiliary housing 3 is set as a rounded surface. The rounded surface can further reduce the obstruction of wind, avoid affecting the wind cup 7's wind sensing ability, and at the same time, the rounded shape can reduce wind resistance and improve stability.

[0061] In some examples, the arc surface can be a hemisphere or an arc structure. The top of the auxiliary housing 3 can be provided with a flat surface to facilitate the installation of the sleeve 5 and the assembly of the rotating shaft 6.

[0062] In some examples, the cross-section of the auxiliary housing 3 is circular along the axis perpendicular to the sleeve 5. The fact that the cross-section of the auxiliary housing 3 is preferably circular, meaning the main body of the auxiliary housing 3 is cylindrical, further reduces wind resistance in all directions and improves its stability.

[0063] In some examples, the auxiliary housing 3 can be cylindrical in shape with a hemispherical surface at the top, or a square plate can be provided at the bottom of the auxiliary housing 3 to facilitate its connection with the corresponding support structure.

[0064] In some examples, the circular diameter of the auxiliary housing 3 does not exceed 8 cm. The smaller size can reduce the impact of the auxiliary housing 3 on the wind cup 7's wind sensing ability, ensuring the accuracy of the monitoring results of the wind speed and direction monitoring device.

[0065] In some examples, the cross-sectional diameter of the auxiliary housing 3 can be specifically designed according to the thickness of the auxiliary housing 3, the size of the transmission component, and the size of the sensing element 4. For example, it can be an outer diameter of 8cm or an outer diameter of 6.5cm.

[0066] Please refer to Figure 1In some examples, the wind speed and direction monitoring device for meteorological services also includes a support column 11, through which the main housing 1 and the auxiliary housing 3 are fixedly connected. The support column 11 can fix the main housing 1 and the auxiliary housing 3 relatively, ensuring the stability of the auxiliary housing 3 and the rotating shaft 6 and sleeve 5 located on the auxiliary housing 3.

[0067] Please refer to Figure 1 In some examples, the support column 11, the main shell 1, and the auxiliary shell 3 can be made of the same material, and the support column 11 can be connected to the main shell 1 and the auxiliary shell 3 by bolts, threads, welding, or bonding. The support column 11 can be a cylinder, a prism, or a frustum.

[0068] Please refer to Figure 1 In some examples, multiple support columns 11 are provided, and the multiple support columns 11 are distributed at intervals. Multiple support columns 11 can further improve the connection strength between the main shell 1 and the auxiliary shell 3.

[0069] In some examples, the number of support columns 11 can be 3 to 6, preferably 3. The multiple support columns 11 can be set vertically or inclined, and the multiple support columns 11 can be distributed at intervals around the edge of the auxiliary shell 3.

[0070] Please refer to Figure 1 In some examples, the wind speed and direction monitoring device for meteorological services also includes a sleeve 12, which is fixedly installed between the main housing 1 and the auxiliary housing 3, connecting the main housing 1 and the auxiliary housing 3, and located between multiple support columns 11. The power supply and control components 2 and the sensing element 4 are connected by wiring, which is arranged inside the sleeve 12. The sleeve 12 facilitates the wiring arrangement and protects the wiring from wind and rain.

[0071] In some examples, the sleeve 12 can be a standalone structure, or a hole can be drilled in one of the multiple support columns 11 to form the sleeve 12. The sleeve 12 can be fixedly connected to the main housing 1 or the auxiliary housing 3, or it can be movably connected or snap-fitted.

[0072] Please refer to Figure 2 In some examples, the shaft 6 is a hollow aluminum alloy shaft. A hollow shaft 6 can have a lighter mass, thereby further reducing the moment of inertia and further improving the sensitivity of the shaft 6, thus improving the sensitivity of the wind speed and direction monitoring device; the aluminum alloy material can provide high strength, and the shaft 6 can be similar to a cantilever beam. By reducing the length of the shaft 6, its bending resistance can be enhanced, ensuring that the shaft 6 has the strength to work stably for a long time.

[0073] In some examples, the two ends of the pivot 6 can be solid, or the top of the pivot 6 can be solid, to prevent water or small insects from entering the auxiliary shell 3 through the internal cavity of the pivot 6.

[0074] Please refer to Figure 2 In some examples, the wind speed and direction monitoring device for meteorological services also includes a sealing ring 51, which is located at the top of the sleeve 5 and has a clearance fit with the rotating shaft 6. The sealing ring 51 can prevent water or insects from entering between the sleeve 5 and the rotating shaft 6, and can protect the sensing element 4.

[0075] In some examples, the sealing ring 51 can be made of silicone rubber, and the sealing ring 51 can be designed as an O-ring with a circular cross-section. The sealing ring 51 can be located only between the rotating shaft 6 and the sleeve 5, or the bottom of the sealing ring 51 can be provided with an annular groove and the sealing ring 51 can extend outside the sleeve 5.

[0076] 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.

[0077] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
