Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of meteorological observation equipment, and particularly relates to a self-maintenance meteorological station support for ice and frozen earth observation. BACKGROUND

[0002] The ice and frozen earth refers to the surface layer composed of the frozen earth landform and its development environment such as glaciers, snow, frozen earth, sea ice, river and lake ice. The change of the ice and frozen earth has important influence on the evolution of climate, water resources, landform environment and geological environment, and is one of the hotspots in the current natural geography research. The essential difference between the ice and frozen earth underlying surface and the ordinary underlying surface is that the ice and frozen earth underlying surface is in a frozen or semi-frozen state, or often undergoes freezing and thawing, so that the surface is in an unstable state. The ablation of glaciers and snow can lower the ground elevation and change the local topography; the frost heaving and thawing of frozen earth can also change the local topography.

[0003] Meteorological observation is a basic work for the ice and frozen earth research. At present, the fixed automatic meteorological station installed by artificial field is widely used for the observation of the ice and frozen earth near-surface layer variables such as air temperature, relative humidity, wind speed and direction, solar radiation and precipitation. The air temperature, relative humidity and wind speed are sensitive to the observation height, that is, the values of these variables observed at different heights are significantly different. The wind speed, wind direction, radiation and precipitation are sensitive to the level, and the sensor must be installed horizontally. The inclination of the sensor will cause significant changes in the values. The wind direction and radiation sensors are sensitive to the direction. The installation horizontal arm of the radiation sensor must face the true south in the northern hemisphere, and the direction marker of the wind direction sensor must face the true north or south, otherwise the values will have large errors.

[0004] The fixed automatic meteorological station usually uses a three-strut or center pole support to install meteorological sensors and data collectors. The three-strut support is composed of three rigid main struts with an included angle of 120 degrees, the two ends of which are connected with the center pole and the ground, and the main struts and the lower part of the center pole are connected by three rigid auxiliary struts to form a stable triangular support. The three-strut support usually needs to be additionally fixed by a steel wire rope. The meteorological sensors and data collectors are installed on the center pole or the horizontal bar fixed on the center pole. The center pole support adopts a center pole and several horizontal bars fixed thereon to install meteorological sensors and data collectors. The bottom of the center pole is directly fixed to the ground by deep burying or flange method. The center pole support also needs to be additionally fixed by a steel wire rope to improve the wind resistance.

[0005] The three-strut or center pole support used in the current automatic meteorological station is a rigid fixed component, which has some deficiencies in the daily observation of the ice and frozen earth environment. The present application will be described as follows:

[0006] Due to the ablation or freezing of ice and snow, the local topography changes, thus easily leading to the tilting of the fixed automatic weather station, thereby causing significant measurement errors of the weather variables sensitive to the levelness, such as wind speed, wind direction, radiation, precipitation, etc.

[0007] The snowfall in the cryosphere environment is often large, and a large amount of snowfall and ice and snow ablation can cause significant changes in the observation height of the meteorological sensor relative to the current ground, thereby causing significant errors of the weather variables sensitive to the observation height, such as air temperature, relative humidity, wind speed, etc. In addition, the tilting of the automatic weather station can also cause changes in the observation height of the meteorological sensor to cause measurement errors. The current automatic weather station support uses rigid connection of pipe materials, does not have automatic adjustment components, and thus cannot cope with the observation errors caused by the tilting of the support or the changes in the observation height.

[0008] The climate in the cryosphere environment is harsh and the topography is complex, and many regions cannot carry out field weather observation due to the inability of personnel to reach, such as the accumulation area of glaciers, high-altitude mountain top areas, deep in uninhabited areas, floating sea ice, etc. Due to the lack of field observation data for a long time in these regions, only remote sensing inversion data or elevation gradient deduction data with large errors can be used to carry out related research, which may lead to research conclusions that deviate from reality.

[0049] It should be noted that the side wall of the movable tube 22 away from the fixed tube 21 is provided with a solar panel through a cross connecting piece, and the solar panel is used to convert solar energy into electrical energy and store it in a battery. The end of the movable tube 22 away from the fixed tube 21 is provided with a weather monitoring part 1 through a cross connecting piece, and the weather monitoring part 1 adopts a weather sensor, which can be one or more of a humidity sensor, a wind speed and direction sensor, etc. The solar power supply and the weather sensor are conventional technical means in the art, and will not be described here.

[0050] The working method of the above embodiment is as follows:

[0051] According to the component installation of the weather station support structure, the component installation is carried out.

[0052] The second spring 424 and the third spring 444 are in an uncompressed state, and the initial sleeving position of the positioning bead plug and the bead plug sleeve should be in the maximum buffering position for impact. That is, as shown in Figure 4 3 first elastic positioning beads 4220 are clamped on the adjacent 3 corresponding first positioning bead limiting holes 4230 closest to the electric push rod 41. As shown in Figure 5 3 second elastic positioning beads 4420 are clamped on the adjacent 3 corresponding second positioning bead limiting holes 4430 farthest from the plug 4431.

[0053] The weather monitoring part 1 is fixedly installed at the top end of the movable tube 22 according to its reasonable relative position; the solar panel is installed on the movable tube 22 below the weather monitoring part 1, and the inclination angle of the solar panel is adjusted to be the same as the latitude of the release area.

[0054] The data acquisition box is installed on the fixed tube 21 above the shell 20, the controller and the weather station support single-chip microcomputer and other electronic equipment are fixedly installed in the data acquisition box, and the data acquisition box is waterproof sealed.

[0055] The attitude adjustment interval of the weather station support is set to 4-24 hours to avoid power consumption caused by frequent attitude adjustment.

[0056] The automatic adjustment test of the posture of the weather station support is carried out to ensure that each component works normally.

[0057] The extension length of the movable tube 22 is shortened as much as possible to reduce the gravity center of the automatic weather station and reduce the probability of overturning after the automatic weather station is dropped by air.

[0058] The automatic weather station is dropped by air by using a hovering aircraft such as a multi-rotor unmanned aerial vehicle. In order to avoid overturning when landing, the weather station has a certain horizontal motion speed when air-dropped by flat flight. In calm weather, the rope fixed to the air-dropping aircraft is connected to the lifting ring 220 by using a controllable thrower, and the automatic weather station is lifted to the air above the installation site. The aircraft is in a hovering state and the hovering height is as low as possible. When the automatic weather station stops swinging and is in a stable state, the automatic weather station is released to fall and land. When the automatic weather station lands, one or more supporting legs 43 contact the ground, and the first buffer rod 42 is subjected to an impact force perpendicular to the contact surface and directed upward. The 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 buffer and insulation cotton wrapped outside the shell 20 can buffer the impact of the shell 20 caused by contact with the ground.

[0059] The controller periodically reads the data collected by the attitude measurement module according to the posture adjustment time interval, and drives one or more electric push rods 41 to make the fixed tube 21 vertical, adjusts the up and down movement of the movable tube 22 by the second motor 231 to make the weather monitoring part 1 at the desired observation height, and adjusts the horizontal rotation of the movable tube 22 by the first motor 33 to make the direction-sensitive sensor in the weather monitoring part 1 face the desired direction.

[0060] The controller should set a reasonable tolerance interval for the data collected by the tilt sensor, magnetometer and distance measuring sensor to avoid posture adjustment due to slight changes in the weather station to save power of the weather station.

[0061] After the automatic weather station is dropped and installed, its posture adjustment is completely automated and does not require manual intervention.
