Description

Technical Field

[0001] The present invention belongs to the technical field of meteorological observation equipment, and in particular relates to an airdroppable and self-maintainable meteorological station bracket for cryosphere observation. Background Art

[0002] The cryosphere refers to the Earth's surface layer composed of frozen landforms such as glaciers, snowpack, permafrost, sea ice, and river and lake ice, as well as the environments in which they develop. Changes in the cryosphere have a significant impact on the evolution of climate, water resources, geomorphic environments, and geological environments, and are currently a hot topic in physical geography. The underlying surface of the cryosphere differs fundamentally from other surfaces in that it is frozen or semi-frozen, or undergoes frequent freeze-thaw cycles, resulting in an unstable surface. For example, the melting of glaciers and snowpack can lower ground elevation and cause changes in local topography. The frost heave and thawing of permafrost can also alter local topography.

[0003] Meteorological observation is a fundamental task in cryosphere research. Currently, fixed automatic weather stations installed on-site are widely used to observe variables such as temperature, relative humidity, wind speed and direction, solar radiation, and precipitation in the near-surface layer of the cryosphere. Among them, meteorological variables such as temperature, relative humidity, and wind speed are highly sensitive to observation, that is, there are significant differences in the values of such variables observed at different altitudes; meteorological variables such as wind speed, wind direction, radiation, and precipitation are sensitive to horizontality. Such variables require that the sensors must be installed horizontally, and tilting of the sensors will cause significant changes in their values; sensors such as wind direction and radiation are sensitive to orientation. The mounting arm of the radiation sensor must face due south in the northern hemisphere, and the orientation mark of the wind direction sensor must face due north or due south, otherwise their values will have large errors.

[0004] Fixed automatic weather stations often use three-strut or center-pole brackets to install equipment such as meteorological sensors and data collectors. The three-strut bracket consists of three rigid main struts at a 120-degree angle, with each end connected to the center pole and the ground. Three rigid secondary struts are then used to connect the main struts to the lower part of the center pole to form a stable triangular support. The three-strut bracket usually requires additional fixing with wire ropes. Meteorological sensors and data collectors are installed on the center pole or on the crossbars fixed to the center pole. The center-pole bracket uses a center pole and several crossbars fixed to it to install meteorological sensors, data collectors and other equipment. The bottom of the center pole is directly fixed to the ground through deep burial or foundation flanges. The center-pole bracket also requires additional fixing with wire ropes to improve its wind resistance.

[0005] The three-strut or center-strut brackets currently used in automatic weather stations are rigid fixed components, which have some shortcomings in daily observations of the cryosphere environment, as explained below: Due to the melting or freezing of ice and snow, the local terrain changes, which can easily cause fixed automatic weather stations to tilt, resulting in significant measurement errors in meteorological variables such as wind speed, wind direction, radiation, and precipitation that are sensitive to horizontality.

[0006] Snowfall in the cryosphere is often heavy. Heavy snowfall and snowmelt can cause meteorological sensors to significantly shift their observation altitude relative to the ground, leading to significant errors in highly sensitive meteorological variables such as temperature, relative humidity, and wind speed. Furthermore, tilting of automatic weather stations can also cause changes in the sensor's observation altitude, leading to measurement errors. Current automatic weather station brackets use rigid tubing connections and lack automated adjustment features, making them unable to address observation errors caused by bracket tilt or changes in observation altitude.

[0007] The cryosphere environment has a harsh climate and complex terrain. There are many areas where field meteorological observations cannot be carried out because people cannot reach them, such as glacier accumulation areas, high-altitude mountaintop areas, deep uninhabited areas, floating sea ice surfaces, etc. Due to the long-term lack of field observation data in these areas, relevant research can only be carried out using remote sensing inversion data or elevation gradient deduction data with large errors, which may lead to research conclusions that are out of touch with reality.

[0043] It should be noted that in this embodiment, a solar panel is mounted on the sidewall of the movable tube 22 away from the fixed tube 21 via a cross connector. The solar panel is used to convert solar energy into electricity and store it in a battery. A meteorological monitoring unit 1 is mounted on the end of the movable tube 22 away from the fixed tube 21 via a cross connector. The meteorological monitoring unit 1 utilizes a meteorological sensor, specifically one or more of a humidity sensor, a wind speed and direction sensor, and other meteorological sensors. Solar power supply and meteorological sensors are conventional technologies in the art and will not be described in detail here.

[0044] The working method of the above embodiment is: Install components according to the weather station bracket structure.

[0045] The second spring 424 and the third spring 444 are both in an uncompressed state, and the initial sleeve position of the positioning bead plug and the bead plug sleeve should be in the maximum buffering position to cope with the impact. Figure 4 As shown, the three first elastic positioning beads 4220 are clamped on the three corresponding adjacent first positioning bead limiting holes 4230 on the side closest to the electric push rod 41. Figure 5 As shown, the three second elastic positioning beads 4420 are clamped on the three corresponding adjacent second positioning bead limiting holes 4430 farthest from the plug 4431.

[0046] The meteorological monitoring unit 1 is fixedly installed on the top of the movable tube 22 according to its reasonable relative position; the solar panel is installed on the movable tube 22 below the meteorological monitoring unit 1, and the tilt angle of the solar panel is adjusted to be the same as the latitude of the deployment area.

[0047] A data acquisition box is installed on the fixed pipe 21 located above the shell 20, and electronic equipment such as the controller and the weather station bracket single chip microcomputer are fixedly installed in the data acquisition box, and the data acquisition box 47 is waterproof and sealed.

[0048] Set the weather station bracket's attitude adjustment interval to 4 to 24 hours to avoid frequent attitude adjustments that may cause power depletion.

[0049] Perform automatic adjustment test of the weather station bracket to ensure that all components are working properly.

[0050] The extended length of the movable tube 22 is shortened as much as possible to lower the center of gravity of the automatic weather station and reduce the probability of the automatic weather station overturning after being airdropped and landing.

[0051] The automatic weather station should be airdropped using a hovering aircraft such as a helicopter or a multi-rotor drone to avoid the weather station from overturning when landing due to its horizontal movement speed during level flight airdrop. Choose a windless day, connect the rope fixed to the airdrop aircraft to the lifting ring 220 using a controllable thrower, lift the automatic weather station and transport it to the installation site. After arriving, the aircraft is in a hovering state and the hovering height is reduced as much as possible. When the automatic weather station stops swinging and is in a stable state, release the automatic weather station and let it fall to the ground. When the automatic weather station lands, one or more legs 43 contact the ground, causing the first buffer rod 42 to be subjected to an impact force perpendicular to the contact surface and pointing upwards. This impact force can be buffered by the first buffer rod 42 and the second buffer rod 44. The inertial motion of the fixed tube 21, the movable tube 22 and the components mounted thereon can be buffered by the buffer 45 and the second buffer rod 44. The buffering and heat-insulating cotton wrapped around the outside of the shell 20 can buffer the impact caused by the shell 20 touching the ground.

[0052] The controller periodically reads the data collected by the attitude measurement module according to the attitude adjustment time interval, drives one or more electric push rods 41 to make the fixed tube 21 vertical, adjusts the movable tube 22 to move up and down through the second motor 231, so that the meteorological monitoring part 1 is at the desired observation height, and adjusts the movable tube 22 to rotate horizontally through the first motor 33, so that the direction-sensitive sensor in the meteorological monitoring part 1 is facing the desired direction.

[0053] The controller should set a reasonable tolerance range for the data collected by the inclinometer, magnetometer, and ranging sensor to avoid attitude adjustments due to slight changes in the weather station, so as to save electricity of the weather station.

[0054] After the automatic weather station is airdropped and installed, its attitude adjustment is fully automated, requiring no human intervention. Data transmission and operational control of the weather station can be performed remotely via wireless connections. When the weather station needs to be repaired or removed, it can be retrieved by aircraft.

[0055] The specific models of the above electronic components are not particularly specified, and common products available on the market can be selected as long as they can meet the use requirements of the present invention.

[0056] The above specific embodiments further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above are only specific embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
