Description

Technical Field

[0001] The invention belongs to the technical field of sea ice stress detection, and in particular relates to a polar sea ice stress buoy. Background Art

[0002] Polar sea ice plays an extremely important role in the global climate system. Its distribution, thickness, and motion have a profound impact on global climate change. Sea ice stress is a key parameter that reflects the mechanical state and interaction of sea ice. Accurately measuring polar sea ice stress is of irreplaceable significance for a deeper understanding of polar ocean dynamics, sea ice evolution, and predicting climate change trends.

[0003] During the use of existing stress buoys, it is first necessary to drill a hole in the ice surface, then place the buoy into the hole, and then position the buoy and the ice surface to ensure that the buoy will not drift around in strong winds. However, during positioning, crushed ice from the drilling process will remain on the water surface. Therefore, during positioning, the positioning block is easily squeezed together with the crushed ice, resulting in unstable positioning. As a result, the buoy may shake as a whole during the detection process, resulting in inaccurate stress detection.

[0054] Then the operator starts the drive motor 2011, and the drive motor 2011 set inside the countersunk groove 1023 drives the turntable 201 to rotate, and the turntable 201 is provided with an extrusion groove 202 of a specific shape.

[0055] After the synchronization rod 203 moves, the slide plate 2031 on the side wall of the synchronization rod 203 can slide on the positioning rod 2032, and the positioning spring 2033 on the positioning rod 2032 is compressed synchronously, so that the positioning spring 2033 is convenient for the subsequent resetting operation, and a positioning plate 2034 is provided at the end of the positioning rod 2032 to ensure that the slide plate 2031 and the positioning rod 2032 will not separate.

[0056] When the synchronization rod 203 is moving, the positions of the descending groove 2064 and the shifting groove 2065 on the synchronization rod 203 change, wherein the guide rod 2063 that can only move vertically is installed inside the descending groove 2064, and then the guide rod 2063 at this time can drive the limit block 206 to move downward, and the limit block 206 slides inside the limit rod 2061, and the limit spring 2062 on the limit rod 2061 is stretched, and the limit spring 2062 is convenient for the later reset operation, and the vibrating wire strain gauge housing 205 at the bottom of the limit block 206 can move downward to ensure that the detection contact 2051 on the vibrating wire strain gauge housing 205 can move to the specified position. When ice forms later, the detection contact 2051 contacts the ice layer, and then the stress is detected by the detection contact 2051, wherein the detection principle of the detection contact 2051 is the existing technology and will not be repeated here.

[0057] After the turntable 201 rotates, the connecting block 3012 on the turntable 201 drives the adjusting roller 301 to rotate, and the knob 3011 on the adjusting roller 301 rotates. When the driving motor 2011 fails to work, the turntable 201 and the adjusting roller 301 are synchronously driven to rotate by rotating the knob 3011, which facilitates the use of the device.

[0058] After the adjusting roller 301 rotates, the guide groove 302 on the adjusting roller 301 rotates. At this time, the guide groove 302 is wavy, and a guide slider 3021 is slidingly arranged inside the guide groove 302. At this time, the guide slider 3021 can move up and down along the guide groove 302 for multiple times. The guide slider 3021 drives the vertical rod 3022 to move vertically up and down for multiple times, and finally the sealing plate 303 at the bottom of the vertical rod 3022 can slide multiple times inside the sealing cover 304.

[0059] When the sealing plate 303 moves downward, the space between the sealing plate 303 and the sealing cover 304 becomes larger. At this time, the water flows inward and can carry a part of the crushed ice to the side of the sealing cover 304, wherein the crushed ice is blocked around the filter screen 3044. Since the position of the crushed ice moves, the floating ice on the outside of the top plate 204 is ensured to be removed. When the sealing plate 303 moves to the base 3041 of the sealing cover 304, the first top column 3041 at the bottom of the base 3041 is 43 can squeeze the cover 3032 so that the pressure plate 3033 on the side wall of the cover 3032 moves along the clamping rod 3034, and the compression spring 3035 on the clamping rod 3034 is compressed synchronously. When the cover 3032 moves upward to a certain extent, the iron plate 3052 on the cover 3032 can be adsorbed on the magnet 3051, and then the water outlet 3031 is opened, and the elastic force of the compression spring 3035 is not enough to separate the iron plate 3052 and the magnet 3051.

[0060] When the sealing plate 303 moves upward, the sealing plate 303 will not push the water to flow out of the filter 3044, and the water can be discharged along the water outlet 3031, ensuring that the floating ice will not be scattered to various positions again, and when the sealing plate 303 moves to the highest point, the second top column 306 squeezes the cover 3032, and the cover 3032 and the magnet 3051 are separated, and under the influence of gravity and the compression spring 3035, the cover 3032 covers the water outlet 3031 again, and the above operation is repeated, and finally the crushed ice can be gathered on the outside of the sealing cover 304, ensuring that the top plate 204 will not be affected by the floating ice during installation, ensuring that the overall equipment can be fixed more stably, and making the stress detection accuracy higher.
