[0002] In the field of meteorological monitoring, the accurate measurement of wind speed and direction is crucial for meteorological research, environmental monitoring, aviation and navigation, agricultural production and many other industries. With the development of technology, various types of meteorological wind speed and direction measuring instruments have emerged to meet the measurement needs in different scenarios.

[0003] Wind speed and direction measuring instruments have a wide range of technical applications, and their measurement principles vary. Commonly used are mechanical anemometers that use wind power to drive mechanical components to rotate and measure wind speed, ultrasonic anemometers that measure wind speed by the speed of ultrasonic wave propagation in air, and measuring instruments based on electromagnetic induction principle, etc. Each type of measuring instrument has its own advantages and disadvantages and plays a role in different scenarios.

[0043] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model patent more clear, the following will combine the drawings of the embodiments of the utility model patent to clearly and completely describe the technical scheme of the embodiments of the utility model patent. Obviously, the described embodiments are part of the embodiments of the utility model patent, not all the embodiments. Based on the described embodiments of the utility model patent, all other embodiments obtained by those skilled in the art belong to the scope of the utility model patent protection.

[0044] The application discloses a meteorological wind speed and direction measuring instrument.

[0045] Reference Figure 1 A meteorological wind speed and direction measuring instrument, comprising a base 1, a lifting rod 2, a barrel 3, an excitation motor 4, a detection fan 5 and an air inlet.

[0046] The base 1 is provided with a lifting rod 2, the lifting rod 2 is provided with a cylinder 3, the cylinder 3 is provided with an excitation motor 4 and a detection fan 5, and the cylinder 3 is provided with a wind inlet.

[0047] When the wind speed needs to be measured, the wind enters the wind inlet, drives the detection fan 5 arranged in the cylinder 3, drives the excitation motor 4 to generate excitation power, detects the current characteristics of the excitation power generation, and the characteristic map is fed back as the size of the wind force.

[0048] In some embodiments, the base 1 is provided with a connecting beam 11, and the connecting beam 11 is connected to the base 1 by bolts.

[0049] Further preferably, the base 1 comprises a circular conical structure and a flange end structure, the two ends of the connecting beam 11 are connected to the nearby working equipment, and the outer side of the base 1 and the connecting beam 11 is sprayed with a wear-resistant plating layer.

[0050] The base 1 is provided with a connecting beam 11 and is connected by bolts, and the two ends of the connecting beam 11 are connected to the nearby working equipment. The bolt connection ensures the stable combination of the base 1 and the connecting beam 11, and the connection of the connecting beam 11 and the working equipment utilizes the stability of the surrounding equipment to closely associate the measuring instrument with the surrounding environment, disperses the weight of the measuring instrument itself and external forces, and enhances the overall stability.

[0051] In some embodiments, the lifting rod 2 is installed on the base 1. The outer side of the lifting rod 2 is provided with a telescopic sleeve 21, and the upper and lower end faces of the lifting rod 2 and the telescopic sleeve 21 are fixedly connected.

[0052] The lifting rod 2 comprises an LPM-1480040 model, an LPM-1730180 model, and a WJ-S10 series.

[0053] The telescopic sleeve 21 realizes the structural protection of the lifting rod 2.

[0054] In some embodiments, the cylinder 3 is vertically arranged, a beam plate 31 is arranged in the lower end face of the cylinder 3, the cylinder 3 is installed on the lifting rod 2, and an air exhaust slit 32 is arranged at the lower end of the cylinder 3.

[0055] The upper end of the lifting rod 2 is fixedly connected to the beam plate 31, the lower end face of the beam plate 31 is provided with a structure reinforcing rib, and the centers of the cylinder 3, the lifting rod 2 and the base 1 are on the same axis.

[0056] The cylinder 3 is fixedly connected to the upper end of the lifting rod 2 through the beam plate 31 at the lower end face, the structure reinforcing rib at the lower end face of the beam plate 31 increases the stress area and the support stiffness to reduce the deformation of the beam plate 31 under load; and the centers of the cylinder 3, the lifting rod 2 and the base 1 are coaxially designed, so that the overall structural gravity center is concentrated on the same vertical line, the wind force load is uniformly distributed, and shaking or vibration caused by gravity deviation is avoided.

[0057] The structural reinforcing rib effectively improves the load-bearing capacity of the beam plate 31 and reduces structural deformation caused by long-term load or external wind; the coaxial design keeps the measuring instrument stable during operation, reduces interference with core components such as the detection fan 5 and the excitation motor 4 due to vibration or inclination, and ensures smooth operation.

[0058] Further preferably, the exhaust slits 32 are arranged in a circumferential array on the side wall of the cylinder 3.

[0059] The exhaust slits 32 are arranged in a circumferential array on the side wall of the cylinder 3, and when the detection fan 5 rotates in the cylinder 3, the airflow formed by the slits is uniformly exhausted, avoiding internal airflow turbulence; the downward inclination of the slits (usually at an angle of 15°-30° to the horizontal) utilizes the principles of gravity and aerodynamics to prevent external rainwater, dust and other impurities from entering the cylinder 3, while not affecting the smooth exhaust of internal airflow.

[0060] The optimized airflow environment in the cylinder 3 ensures that the rotational speed of the detection fan 5 is linearly related to the wind speed, improving the accuracy of wind speed measurement; reduces the frequency of equipment maintenance due to impurities entering, reduces the use cost, and is especially suitable for outdoor environments with more dust or rain.

[0061] In some embodiments, the excitation motor 4 is arranged on the beam plate 31, a sealing cover plate 41 is arranged on the excitation motor 4, and the sealing cover plate 41 is in abutment with the inner side wall of the cylinder 3. The detection fan 5 is connected to the excitation motor 4 through the sealing cover plate 41, and the detection fan 5 is arranged in the cylinder 3.

[0062] The exhaust slits 32 are arranged between the sealing cover plate 41 and the detection fan 5.

[0063] The exhaust slits 32 are arranged on the upper side of the sealing cover plate 41.

[0064] The excitation motor 4 is fixedly installed on the beam plate 31 at the lower end of the cylinder 3, and its drive shaft is rigidly connected to the detection fan 5 in the cylinder 3 after penetrating the sealing cover plate 41.

[0065] When external airflow enters the cylinder 3 through the air inlet, the detection fan 5 is driven to rotate by the wind force, driving the drive shaft of the excitation motor 4 to rotate synchronously, and the electromagnetic induction components (such as coils and permanent magnets) inside the excitation motor 4 cut the magnetic induction lines to generate an induced electromotive force. By detecting the frequency or amplitude change of the electromotive force, the wind speed can be calculated.

[0066] The sealing cover plate 41 is in abutment with the cylinder body 3 to form a physical seal for the excitation motor 4, preventing external dust, rain and other impurities from entering the motor interior, and isolating the motor from the airflow environment inside the cylinder body 3 to ensure that the motor operates in a clean and dry environment.

[0067] The detection fan 5 forms a stable airflow sensing area inside the cylinder body 3, avoiding direct impact of external turbulence on the motor and reducing mechanical vibration interference on the measurement signal, thereby improving the accuracy and repeatability of wind speed measurement.

[0068] Further preferably, a shock-absorbing cushion layer is arranged in the cylinder body 3.

[0069] A shock-absorbing cushion layer (usually made of elastic materials such as rubber, silicone or spring structure) is arranged inside the cylinder body 3 or at the key position where the cylinder body 3 is connected to the lifting rod 2, which absorbs external vibration energy by elastic deformation.

[0070] When the measuring instrument is subjected to external vibration (such as vehicle bumps, device shaking caused by strong wind, industrial machinery vibration, etc.), the shock-absorbing cushion layer converts the kinetic energy generated by vibration into heat energy or elastic potential energy through compression, stretching or shear deformation, thereby attenuating the vibration transmission to the detection fan 5, excitation motor 4 and other precision components inside the cylinder body 3, reducing the vibration amplitude thereof.

[0071] In some embodiments, the air inlet includes an L-shaped air intake structure 6, an arc-shaped baffle 7 connected to the L-shaped air intake structure 6, and a wind vane 8 installed on the L-shaped air intake structure 6.

[0072] The wind vane 8 includes an indicating arrow 81 and a driven wind plate 82 connected to the indicating arrow 81.

[0073] The driven wind plate 82 is connected to the indicating arrow 81 and installed on the L-shaped air intake structure. When the airflow acts on the driven wind plate 82, the wind plate is pushed to rotate by the wind force, driving the indicating arrow 81 to point to the airflow direction, and the wind direction is fed back in real time through the angle change of the wind vane 8 rotating shaft 83.

[0074] The large-area design of the driven wind plate 82 increases the contact area with the airflow, which can quickly rotate even at low wind speed.

[0075] The outflow end sleeve of the L-shaped air intake structure 6 is arranged outside the cylinder body 3, and a baffle ring 61 is arranged inside the outflow end of the L-shaped air intake structure 6, which is in rotational constraint abutment with the upper end surface of the cylinder body 3.

[0076] The air inlet end faces the external airflow, and the air outlet end is sleeved and rotationally constrained to the baffle ring 61 on the upper end of the cylinder body 3, forming an "L"-shaped air guide path.

[0077] After the external airflow enters from the air inlet end, it changes direction through the L-shaped channel, and is introduced into the inside of the cylinder 3 where the detection fan 5 is located, using geometric flow guiding to reduce airflow turbulence.

[0078] The arc-shaped baffle 7 is in sliding abutment with the outer sidewall of the cylinder 3, and the lower end surface of the arc-shaped baffle 7 and the cylinder 3 is parallel.

[0079] The rotation constraint of the arc-shaped baffle 7 and the cylinder 3 ensures that the L-shaped air sampling structure can rotate freely around the center of the cylinder 3, and the sliding abutment of the arc-shaped baffle 7 allows it to rotate synchronously with the air sampling structure, maintaining dynamic adaptation to the airflow.

[0080] The air outlet slits 32 on one side of the external airflow are closed and blocked to prevent external airflow from entering the cylinder 3 through the air outlet slits 32, forming a reverse flow of wind speed and affecting the measurement accuracy.

[0081] The wind speed airflow entering the cylinder 3 is discharged through the air outlet slits 32 that are not blocked by the arc-shaped baffle 7, forming a one-way movement of the wind speed airflow.

[0082] The structure of the embodiment: a plurality of air outlet slits 32 are arranged in a surrounding array on the sidewall of the cylinder 3 and are inclined downward (with an angle of 15°~30° to the horizontal plane).

[0083] When the external airflow impacts from any direction, the L-shaped air sampling structure rotates synchronously with the wind vane 8 to the windward side. The arc-shaped surface of the L-shaped air sampling structure covers and blocks the air outlet slits 32 in that direction, leaving only the leeward side of the air outlet slits 32 in an open state. At this time, the external airflow enters the cylinder 3 from the air inlet end of the L-shaped air sampling structure, drives the detection fan 5 to rotate, and then is discharged through the leeward side of the air outlet slits 32 that are not blocked by the arc-shaped baffle 7, forming a one-way airflow path of "air inlet end suction, cylinder 3 internal driving detection, and leeward end discharge", avoiding the reverse flow of external airflow from the air outlet slits 32.

[0084] In some embodiments, the excitation motor 4 is a hollow motor, the excitation motor 4 is installed on the beam plate 31 through the support rod 42, and the wind vane 8 is connected to the rotating shaft 83; the rotating shaft 83 penetrates the L-shaped air sampling structure 6 and the drive shaft in the excitation motor 4 in sequence and is connected to the electronic compass 84.

[0085] The rotating shaft 83, the drive shaft in the excitation motor 4, the sealing cover plate 41, and the inner sidewall of the cylinder 3 are in abutment in sequence.

[0086] The rotating shaft 83 is fixedly connected to the L-shaped air sampling structure 6.

[0087] The excitation motor 4 is a hollow motor (i.e., a hollow shaft motor), which is fixedly installed on the beam plate 31 at the lower end of the cylinder 3 through the support rod 42, and the hollow shaft structure allows the rotating shaft 83 of the wind vane 8 to penetrate through it.

[0088] The rotation shaft 83 is connected with the driving wind plate 82 and the indicating arrow 81 at one end and connected with the electronic compass 84 at the other end.

[0089] Wherein, in combination with referring to Figure 2 It is the structural schematic view of the electric appliance element connection in the utility model patent.

[0090] The PLC program control board is connected with the excitation motor 4, the electronic compass 84, the battery and the wireless transmission communication module respectively.

[0091] The design realizes the intelligentization, unmanned and network technology support of the measuring instrument by the core control effect of the PLC program control board, the organic combination of the mechanical structure, the sensor and the communication module.

[0092] In some embodiments, the inlet end face of the L-shaped air sampling structure 6 is a beveled port, and the inlet of the L-shaped air sampling structure 6 is provided with a screen 62, and the beveled port is an inwardly inclined opening.

[0093] The inlet end face of the L-shaped air sampling structure is designed as an inwardly inclined beveled port (usually at an angle of 30°~45° with the horizontal plane), which utilizes the flow guiding effect of the beveled port to efficiently guide the external airflow into the air sampling channel; the screen 62 (such as a metal mesh with a pore size of 0.5~1mm) at the inlet blocks larger impurities such as leaves and insects, preventing them from blocking the internal flow channel or damaging the detection fan 5.

[0094] The composite structure of the inclined port and the screen 62 ensures that the airflow entering the cylinder 3 is clean and concentrated in direction.

[0095] The screen 62 adopts a quick-release structure (such as magnetic attraction or buckle connection), which is convenient for regular cleaning and takes into account efficient air guiding and convenient maintenance.

[0096] In some embodiments, the guide ring 63 is provided on the blocking ring 61, and the cross section of the guide ring 63 is a triangular structure, and the lower end face of the triangular structure completely coincides with the cross section of the guide ring 63.

[0097] The guide ring 63 on the blocking ring 61 adopts a triangular cross section, and the lower end face thereof completely coincides with the cross section of the blocking ring 61, forming a "triangular guide rib". When the L-shaped air sampling structure rotates around the cylinder 3, the air resistance during rotation of the air sampling structure is reduced, and at the same time, the airflow is prevented from forming a vortex at the gap between the blocking ring 61 and the cylinder 3.

[0098] In some embodiments, the driving wind plate 82 includes two groups of arc-shaped spoiler plates, and the front ends of the two spoiler plates are connected with the indicating arrow 81.

[0099] The driving wind plate 82 is composed of two groups of arc-shaped spoiler plates, and the front end is rigidly connected with the indicating arrow 81. The curved surface design of the arc-shaped spoiler plate increases the contact area with the airflow (30% higher than the flat plate type wind plate), and when the airflow blows from any direction, the two groups of spoiler plates generate a rotating torque due to the force difference, which pushes the indicating arrow 81 to quickly point to the wind direction. The arc-shaped curved surface has a “wind gathering” effect, which can generate enough driving force even at low wind speed (≥1 m / s).

[0100] In some embodiments, the edges of the arc-shaped baffle 7 are rounded, and the air inlet of the L-shaped air collecting structure 6 and the opening of the arc-shaped baffle 7 are parallel to each other.

[0101] The edges of the arc-shaped baffle 7 are rounded with an R5~R10mm radius, which eliminates the sharp corner separation phenomenon when the airflow passes through, reduces turbulence and noise.

[0102] Avoid scratching the operating personnel.

[0103] In some embodiments, the central angle of the arc-shaped baffle 7 is not less than 180 degrees.

[0104] Further preferably, the central angle of the arc-shaped baffle 7 is 270 degrees,

[0105] The air inlet of the L-shaped air collecting structure and the opening direction of the arc-shaped baffle 7 are strictly parallel (deviation <1°), which ensures that the airflow is introduced in the same direction and avoids the airflow from colliding due to angle deviation;

[0106] Large central angle (≥180°, preferably 270°): the arc-shaped baffle 7 covers the 180°~270° area of the circumference of the cylinder 3, only leaving 90°~180° opening as the leeward side exhaust channel, forming an asymmetric structure of “large area blocking + small opening guiding”, forcing the airflow to enter from the air inlet in one direction.

[0107] The side wall of the cylinder 3 is provided with a plurality of downward inclined ring array exhaust slits 32, which block the invasion of rain and dust by using gravity and inclination angle, while allowing the airflow in the cylinder 3 to be uniformly discharged, avoiding internal turbulence.

[0108] An elastic material pad is provided inside the cylinder 3 to absorb external vibration energy, reduce interference to the detection fan 5 and the excitation motor 4, and improve measurement stability.

[0109] The sealing cover plate 41 is in abutment with the cylinder 3, the edges of the arc-shaped baffle 7 are rounded and parallel to the air inlet, combined with the screen 62 and the flow guide ring 63, to achieve I dust and water proofing, suitable for dust and rain environment.

[0110] Through the geometric structure of the L-shaped inclined port, the triangular cross-section flow guide ring 63 and the arc-shaped baffle 7, the airflow in any direction is converted into axial unidirectional flow, filtering impurities and reducing turbulence;

[0111] The embodiment of the application is a meteorological wind speed and direction measuring instrument, and the implementation principle is as follows:

[0112] The lifting rod 2 is sleeved with the telescopic sleeve 21 outside, and the height adjustment is realized through the fixed connection of the upper and lower end faces, so that different measurement height requirements can be met, and it is ensured that the air inlet is in the target air flow layer.

[0113] The inclined port (inwardly inclined) of the air inlet is matched with the screen 62 to filter large particle impurities and guide the airflow to turn, and the airflow is further straightened through the triangular flow guide ring 63 on the baffle ring 61 to ensure that the airflow is stably introduced along the axis of the cylinder body 3.

[0114] The arc-shaped baffle 7: the arc-shaped curved surface with a central angle ≥180° (preferably 270°) is in sliding abutment with the cylinder body 3 and rotates synchronously with the wind vane 8, blocks the windward side exhaust slot 32, and only opens the leeward side slot, forming a one-way airflow path of “air inlet on the windward side and exhaust on the leeward side”, and preventing backflow.

[0115] The wind vane 8: the driving wind plate 82 (double-arc-shaped spoiler) is rotated by the airflow, and the indicating arrow 81 and the electronic compass 84 are driven by the rotating shaft 83 to point to the wind direction in real time. The arc-shaped spoiler increases the contact area and improves the response sensitivity at low wind speed.

[0116] Wind speed measurement: the external airflow is introduced into the cylinder body 3 through the air inlet, and drives the detection fan 5 to rotate, and the fan drives the excitation motor 4 (hollow motor) to rotate through the driving shaft; the excitation motor 4 generates an electrical signal, which is filtered and converted by the PLC program control board to obtain the real-time wind speed value (unit: m / s).

[0117] Wind direction measurement: the driving wind plate 82 is rotated by the air flow thrust, and the rotating shaft 83 penetrates the L-shaped air inlet structure 6 and the hollow motor, and is coaxially connected with the electronic compass 84; the electronic compass 84 senses the angle change of the rotating shaft 83 in real time, and outputs the wind direction angle signal (accuracy ±1°), which is processed by the PLC program control board and integrated with the wind speed data synchronously.

[0118] The PLC program control board controls: synchronously receives the wind speed electrical signal of the excitation motor 4 and the wind direction digital signal of the electronic compass 84, generates standard meteorological data (wind speed, wind direction, equipment status), and realizes data interaction through the wireless transmission communication module.

[0119] The height adjustment of the lifting rod 2, the shock-absorbing pad layer, the large central angle arc-shaped baffle 7 and other designs enable the device to work stably in a narrow space, complex airflow and vibration environment, and break through the scene limitation of traditional measuring instruments.

[0120] The measuring instrument realizes high-precision measurement of wind speed and direction in a compact volume by deeply integrating aerodynamics, mechanical transmission and intelligent control technology through the three-layer architecture of "mechanical structure optimization of airflow path, accurate capture of motion signals by sensors, and intelligent control to realize data processing and transmission", and is especially suitable for complex environments such as city high-rise gaps, vehicle mobile, and small space in the wild, thereby providing an innovative solution of "small volume, high performance, and easy deployment" for meteorological monitoring.
