Description

Technical Field

[0001] This invention belongs to the field of meteorological monitoring technology, specifically a multi-parameter meteorological monitoring device for preventing freezing during wind power construction in high-altitude and cold regions. Background Technology

[0002] When constructing wind turbine generators in high-altitude plateau regions (such as the Qinghai-Tibet Plateau and the western Sichuan Plateau), the meteorological environment at the construction site is extremely harsh. The alternating effects of strong winds, blizzards, freezing rain, and intense solar radiation place extremely high demands on construction safety, the judgment of hoisting operation windows, and the operational status of equipment. Therefore, deploying meteorological monitoring devices capable of real-time monitoring of multiple parameters such as wind speed, wind direction, temperature, and humidity is a necessary prerequisite for ensuring the safety and progress of wind power construction.

[0003] Currently, the meteorological monitoring devices commonly used in wind power construction mainly follow the traditional ground-based meteorological station model, which involves installing anemometers and temperature / humidity sensors at a single height using fixed supports. The anemometers and sensors in these traditional devices are fixed at a specific height and orientation on the support pole, and their measurements only represent the instantaneous airflow parameters at that single point in space. However, fixed single-point sensors are prone to falling into areas of localized airflow distortion, resulting in significant deviations from the "regional average incoming wind speed," which is of great interest to construction and hoisting operations. This makes it difficult to accurately reflect the true wind field conditions at the work site, leading to frequent false alarms or missed warnings for hoisting safety. Furthermore, in high-altitude areas, winter temperatures are low, and supercooled water droplets in the air quickly condense into ice upon contact with the anemometer cups. The surface of the traditional anemometer cups is easily covered by ice, causing a sharp increase in rotational resistance. When the ice reaches a certain level, the cups become completely jammed, the rotation speed drops to zero, resulting in continuously zero or severely underestimated wind speed data, creating a "false calm wind" state. If a sudden gust of wind occurs, the frozen wind cups will not respond, which can easily lead to construction safety accidents.

[0004] Therefore, it is necessary to provide a multi-parameter meteorological monitoring device for preventing freezing during wind power construction in high-altitude and cold regions, in order to solve the problems mentioned in the background technology. Summary of the Invention

Detailed Implementation

[0043] Please see Figures 1-6 In this embodiment of the invention, a multi-parameter meteorological monitoring device for preventing freezing during high-altitude and cold-climate wind power construction includes:

[0044] The lower end face of the upright support 1 is anchored to the ground through the base to ensure structural stability under harsh geological conditions such as strong winds and frozen soil;

[0045] The photovoltaic panel unit 11 is installed on the pole support 1 to convert solar energy into electrical energy, providing power to the entire monitoring device and meeting the long-term power supply needs of remote high-altitude areas.

[0046] Wind direction monitoring device 2 is installed on the pole support 1 and located above the photovoltaic panel unit 11;

[0047] The support beam 12 is horizontally fixed to the upper end of the upright bracket 1;

[0048] Camera 13 is installed below the end of the support beam 12 and is used to monitor the environmental images of the construction area in real time.

[0049] The central control box 14 is fixed on the pole support 1 and located below the wind direction monitoring device 2. It integrates a battery, a data acquisition unit, a wireless communication module and a microprocessor to process the signals from various sensors and transmit data remotely.

[0050] In this embodiment, the photovoltaic panel unit 11 is composed of at least two symmetrically distributed solar panels. Each solar panel is tilted on the pole support 1 by adjusting the bracket. This symmetrical tilting arrangement can not only maximize the photoelectric conversion efficiency under different solar angles, but also effectively reduce the windward area and reduce the impact of wind load on the pole support 1.

[0051] The support beam 12 is equipped with a temperature and humidity monitoring device. The temperature and humidity monitoring device and the wind direction monitoring device 2 together form a multi-parameter monitoring system to provide comprehensive meteorological data such as wind speed, wind direction, temperature, and humidity for wind power construction.

[0052] In a preferred embodiment, the wind direction monitoring device 2 includes a positioning sleeve 21, a fixing ring seat 22, multiple fixing columns 23, a wind speed monitoring device 3, and a wind direction sensor 24. The positioning sleeve 21 is fixedly mounted on the pole support 1, and the fixing ring seat 22 is coaxially rotatably connected to the positioning sleeve 21, so that the entire upper monitoring assembly can rotate freely around the axis of the pole support 1, realizing dynamic movement during the monitoring process.

[0053] Multiple fixed posts 23 are evenly distributed along the circumference of the fixed ring seat 22. One end of each fixed post 23 is connected to the fixed ring seat 22, and the other end is equipped with a wind speed monitoring device 3. A wind direction sensor 24 is installed on one side of the upper end face of each wind speed monitoring device 3. In this structure, the multiple fixed posts 23 form a "star-shaped" or "radial" distribution in space, which can simultaneously capture the instantaneous wind speed at different points in space, effectively overcoming the local turbulence error caused by fixed-point wind speed monitoring.

[0054] In this embodiment, the fixed column 23 is rotatably connected to the fixed ring seat 22, and the mounting sleeve 25 is coaxially fixed above the fixed ring seat 22. Multiple connecting rods 26 are hinged on the mounting sleeve 25, and the other end of each connecting rod 26 is hinged to a support rod 27. An extension frame 28 is fixed on the fixed column 23, and the other end of the support rod 27 is rotatably connected to the extension frame 28.

[0055] The wind speed monitoring device 3 is rotatably connected to the fixed column 23, and a counterweight 29 is provided below the wind speed monitoring device 3. This arrangement allows each wind speed monitoring device 3 to swing up and down with the deflection of the fixed column 23. Simultaneously, the fixed ring seat 22 rotates continuously under wind force, enabling dynamic multi-point wind speed monitoring. Traditional single-point monitoring can only obtain instantaneous wind speed at a fixed height and direction. In this solution, the continuous rotation of the fixed ring seat 22 causes each wind speed monitoring device 3 to perform a circular sweep in the horizontal plane. This, combined with the up-and-down undulation caused by the deflection of the fixed column 23, creates a spatial spiral or wavy surface on the trajectory of each monitoring point, constructing a three-dimensional monitoring field and significantly improving wind speed monitoring accuracy. Furthermore, if a traditional single-point sensor happens to be located in an eddy current region, the data will be severely distorted. This invention uses multiple sensors to continuously change spatial positions. The processor in the central control box can perform spatiotemporal weighted fusion of data from various times and directions, effectively smoothing out random errors caused by local obstacles or turbulence. The output wind speed value is the effective spatial mean, which is closer to the actual incoming wind speed in the construction area and eliminates random errors caused by local airflow interference.

[0056] In this embodiment, the wind speed monitoring device 3 maintains a vertical state throughout the rotation of the fixed column 23. That is, the center of gravity of the wind speed monitoring device 3 is located directly below the rotation connection point (center of the rotating shaft), and the vertical central axis of the device coincides with the line connecting the center of gravity to the rotation point, forming a "suspended" stable structure. A guide ring 4 is coaxially fixed on the positioning sleeve 21 below the fixed ring seat 22. A wave-shaped guide groove 41 is provided on the outer wall of the guide ring 4, and multiple sliders are slidably arranged in the wave-shaped guide groove 41.

[0057] Each slider is inclinedly connected to a top rod 42, the other end of which is connected to the connecting rod 26. With this configuration, when the fixed ring seat 22 rotates continuously, causing each wind speed monitoring device 3 to make circular motion in the horizontal plane, the top rod 42 below the wind speed monitoring device 3 can rotate synchronously around the center of the fixed ring seat 22 with the wind speed monitoring device 3. At this time, the slider below the top rod 42 slides along the wave guide groove 41, thereby causing the fixed column 23 to generate periodic upward reciprocating oscillation. This can not only realize synchronous dynamic monitoring of multiple monitoring points, but also reduce random errors. In addition, it can also avoid the reduction in rotation speed of the wind speed monitoring device 3 due to accelerated freezing of the surface under traditional static conditions, thus achieving the effect of assisting in ice breaking and making the ice layer of the wind speed monitoring device 3 easier to peel off.

[0058] In this embodiment, the wind speed monitoring device 3 includes an air inlet base 31, a support slide 33, a base plate 34, a wind speed sensor 35, and a dust cover 36. Multiple air inlets 32 are circumferentially distributed on the outer wall of the air inlet base 31, and dust filters are preferably provided at the air inlets 32 to filter sand and ice crystals in the air and prevent large particles from entering the device. The support slide 33 is centrally located inside the air inlet base 31 and can slide up and down along the inner wall of the air inlet base 31. Multiple base plates 34 are symmetrically fixed to the upper surface of the support slide 33. The wind speed sensor 35 is rotatably mounted on the upper surface of the base plate 34.

[0059] A dust cover 36 is positioned above the supporting slide 33. Multiple sliding rods 37 are vertically fixed above the air inlet base 31, and the dust cover 36 is slidably connected to the sliding rods 37. Under normal or extreme low-temperature blizzard conditions, the dust cover 36 covers the upper port of the air inlet base 31, protecting the wind speed sensor 35 inside the air inlet base 31. At this time, air only enters through the air inlet 32, and the wind speed sensor 35 operates and rotates safely to maintain basic wind speed monitoring functions.

[0060] In a preferred embodiment, a dustproof net is provided at the air inlet 32; the support slide 33 is slidably installed in the air inlet seat 31, and a central shaft 38 is vertically slidably arranged in the air inlet seat 31. The central shaft 38 slides through the support slide 33, and the upper end of the central shaft 37 is fixed to the dustproof cover 36.

[0061] An internal spring is provided between the central shaft 38 and the support slide 33. A lead screw 39 is vertically rotatably connected to the lower part of the air inlet seat 31. A positioning frame plate is threadedly slidably connected to the lead screw 39. The lower end of the central shaft 38 is fixed to the positioning frame plate.

[0062] When improved monitoring accuracy or calibration is required, the support slide 33 is driven upward by the lead screw 39. Since the upper end of the central shaft 38 is fixed to the dust cover 36, the rise of the central shaft 38 first lifts the dust cover 36 and the support slide 33, causing them to rise synchronously. When the support slide 33 reaches its limit position, the wind speed sensor 35 is outside the air inlet seat 31. Then, the dust cover 36 continues to rise and reaches its highest point, compressing the inner spring and completely separating the dust cover 36 from the support slide 33. At this point, the wind speed sensor 35 is fully exposed to natural wind, eliminating the throttling effect and wind resistance of the air inlet 32, thereby obtaining the most accurate wind speed data.

[0063] In this embodiment, a rotating shaft 51 is vertically rotatably connected inside the housing 5 of the wind speed sensor 35. A sliding shaft 52 is slidably disposed at the upper end of the rotating shaft 51. The sliding shaft 52 is fixed to the wind cup of the wind speed sensor 35. A axial pressure ring 53 is fixed on the sliding shaft 52, and a toothed grooved disk 54 is slidably disposed on the sliding shaft 52 below the axial pressure ring 53. The toothed grooved disk 54 abuts against the axial pressure ring 53. During wind speed monitoring, the sliding shaft 52 and the rotating shaft 51 can rotate synchronously with the wind cup.

[0064] In this embodiment, a support spring is connected below the axial pressure ring 53. The support spring can provide elastic tension in its natural state, so that the sliding shaft 52 in the axial pressure ring 53 can remain retracted to the rotating shaft 51. The toothed disc 54 has teeth distributed on its surface. The teeth on the surface of the toothed disc 54 can achieve axial vibration of the axial pressure ring 53 when it is in full contact with the protrusions on the surface of the axial pressure ring 53. That is, the axial pressure ring 53 rotates with the rotating shaft 51, while the toothed disc 54 does not rotate with the sliding shaft 52. At this time, a relative rotation occurs between the toothed disc 54 and the axial pressure ring 53. If the toothed disc 54 and the axial pressure ring 53 are in full contact at this time, when the toothed disc 54 rotates, it can continuously cycle with the protrusions of the axial pressure ring 53 in a "meshing-lifting-sliding-springing" cycle. Thus, for every rotation of the wind cup, the sliding shaft 52 will experience dozens of up-and-down undulations, forming a self-excited high-frequency axial micro-vibration. In this way, the wind cup is superimposed with high-frequency axial vibration while rotating at high speed. This allows for the complete detachment of the interface between the supercooled water droplets or thin ice layer adhering to the outer wall of the wind cup and the metal surface, thus achieving autonomous de-icing.

[0065] In this embodiment, a thrust ring 55 is slidably disposed inside the housing 5, and the thrust ring 55 is fixed to the toothed disc 54. A magnet 56 is disposed on the lower end face of the thrust ring 55. An electromagnetic base 57 is fixed inside the housing 5. The electromagnetic base 57 and the magnet 56 are opposite in polarity and repel each other. That is to say, when de-icing is required, the electromagnetic base 57 can repel the magnet 56 when it is powered on, and the thrust ring 55 moves axially upward, thereby driving the toothed disc 54 to fully contact the axial pressure ring 53, and the support spring is stretched, realizing the wind cup's autonomous de-icing, with a significant de-icing effect.

[0066] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
