A polar sea ice stress buoy

Abstract

The present invention relates to the technical field of sea ice stress detection, and discloses a polar sea ice stress buoy, which includes a floating unit, a positioning and detection unit, and an ice floe cleaning unit. By providing a positioning and detection unit in the present invention, when positioning operation is required, the operator starts the drive motor, which drives the turntable to rotate through the drive motor. At this time, the position of the extrusion groove on the turntable changes, and the extrusion groove pushes the entire synchronous rod to move. The synchronous rod can drive the top plate at the end to move towards the side wall of the ice hole to complete the extrusion positioning operation. And when the synchronous rod slides, the position of the descending groove on the synchronous rod changes, and the descending groove drives the limit block to slide downward, which can further drive the housing of the vibrating wire strain gauge to move downward, so as to move to the stress detection area. Through the above method, the operations of positioning and moving the vibrating wire strain gauge to the detection position can be completed synchronously, making the operation simpler.

Description

Technical Field

[0001] The present invention belongs to the technical field of sea ice stress detection, and specifically 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 characteristics such as distribution, thickness, and motion state have a profound impact on global climate change. Sea ice stress is a key parameter reflecting the mechanical state and interaction of sea ice. Accurately measuring polar sea ice stress is of irreplaceable significance for deeply understanding polar ocean dynamics, sea ice evolution laws, and predicting climate change trends.

[0003] During the use of existing stress buoys, first, holes need to be drilled in the ice surface, then the buoy is placed into the holes, and then the buoy and the surrounding ice surface are positioned to ensure that the buoy does not float around with strong winds. However, during the positioning process, broken ice chips from the drilling process will remain on the water surface. Therefore, during the positioning, the positioning blocks are likely to be squeezed together with the broken ice chips, resulting in unstable positioning. Furthermore, during the detection process, the entire buoy may shake, leading to inaccurate stress detection.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0017] As a preferred embodiment of the present invention, an installation groove is formed on the sealing plate, a clamping rod is installed on the installation groove, a pressing plate is movably inserted on the side wall of the clamping rod, the side wall of the pressing plate is connected to the sealing plate, and a sealing gasket is arranged at the bottom of the sealing plate.

[0018] As a preferred embodiment of the present invention, a clamping plate is installed at the top of the clamping rod, a compression spring is sleeved on the clamping rod between the clamping plate and the pressing plate, two ends of the compression spring are respectively clamped on the pressing plate and the clamping plate, and the height of the top of the clamping rod is higher than the height of the positioning support.

[0019] The present invention has the following beneficial effects compared with the prior art:

[0020] By providing a positioning detection unit, when a positioning operation is required, the operator starts the driving motor, the driving motor drives the turntable to rotate, the position of the extrusion groove on the turntable changes, the extrusion groove pushes the whole synchronous rod to move, the synchronous rod can drive the top plate at the end to move towards the side wall of the ice hole to complete the extrusion positioning operation, and when the synchronous rod slides, the position of the descending groove on the synchronous rod changes, the descending groove drives the limiting block to slide downwards, and then can drive the outer shell of the vibrating wire strain gauge to move downwards, so as to move to the stress detection area. Through the above method, the operations of positioning and moving the vibrating wire strain gauge to the detection position can be completed synchronously, making the operation simpler.

[0021] By setting up an ice floe cleaning unit, when the turntable rotates, the position of the adjusting roller on the turntable changes. The guiding chute on the adjusting roller can drive the vertical rod to move up and down multiple times, and the sealing plate at the bottom of the vertical rod slides vertically back and forth synchronously inside the sealing cover. When the sealing plate moves downward, the chamber space above the sealing plate and the sealing cover becomes larger. At this time, water flows inward and can carry a part of the broken ice to move towards one side of the sealing cover, ensuring that the ice floes outside the top plate are removed. When the sealing plate moves to the bottom, the first ejector post at the bottom can squeeze the cover, causing the cover to adsorb on the magnet. At this time, the water outlet is opened. When the sealing plate moves upward, the sealing plate will not push the water to flow out from the filter screen, ensuring that the ice floes will not float again. And when the sealing plate moves to the highest point, the second ejector post squeezes the cover. At this time, the cover and the magnet are separated, and under the influence of gravity, the cover covers the water outlet again. Repeating the above operations, finally, the broken ice can be gathered outside the sealing cover, ensuring that when the top plate is installed, it will not be affected by the ice floes and ensuring that the overall equipment can be fixed more stably.

Detailed implementation mode

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0039] Embodiment 1:

[0040] As Figures 1 to 10 shown, a polar sea ice stress buoy includes a floating unit 100, a positioning and detecting unit 200, and a floating ice cleaning unit 300.

[0041] The floating unit 100 includes a floating cover 101. An installation cover 102 is arranged at the bottom of the floating cover 101. A positioning sleeve 1021 is installed on the installation cover 102. A positioning cover 103 is installed on the top of the floating cover 101.

[0042] The positioning and detecting unit 200 includes a turntable 201. The turntable 201 is arranged inside the installation cover 102. A driving motor 2011 is installed at the rotation center of the turntable 201. An extrusion groove 202 is formed on the turntable 201. The extrusion groove 202 is arc-shaped. A side plate 2022 is slidably arranged on the extrusion groove 202. A synchronizing rod 203 is installed on the side plate 2022. The synchronizing rod 203 movably penetrates through the positioning sleeve 1021. A top plate 204 is installed on the synchronizing rod 203 on the side wall of the positioning sleeve 1021. The top plate 204 is arc-shaped. A descending groove 2064 is formed on the side wall of the synchronizing rod 203. A displacement groove 2065 is formed at the end of the descending groove 2064. The descending groove 2064 is in an inclined state. A limiting block 206 is slidably arranged inside the descending groove 2064. A vibrating wire strain gauge housing 205 is installed at the bottom of the limiting block 206. The vibrating wire strain gauge housing 205 is movably inserted into the positioning sleeve 1021. A detection contact 2051 is installed on the surface of the vibrating wire strain gauge housing 205. When positioning operation is required, the operator starts the driving motor 2011 to drive the turntable 201 to rotate through the driving motor 2011. Then the position of the extrusion groove 202 on the turntable 201 changes. The extrusion groove 202 pushes the whole synchronizing rod 203 to move. The synchronizing rod 203 can drive the top plate 204 at the end to move towards the side wall of the ice hole to complete the extrusion positioning operation. When the synchronizing rod 203 slides, the position of the descending groove 2064 on the synchronizing rod 203 changes. The descending groove 2064 drives the limiting block 206 to slide downwards, and then can drive the vibrating wire strain gauge housing 205 to move downwards, so as to move to the stress detection area. Through the above method, the operations of positioning and moving the vibrating wire strain gauge housing 205 to the detection position can be completed synchronously, making the operation simpler.

[0043] The floating ice cleaning unit 300 includes an adjusting roller 301. The adjusting roller 301 is rotatably installed inside the positioning cover 103. The adjusting roller 301 is connected to the turntable 201. A guiding chute 302 is formed on the adjusting roller 301. The guiding chute 302 is wavy. A vertical rod 3022 is slidably arranged on the guiding chute 302. The vertical rod 3022 movably penetrates through the mounting cover 102. A sealing plate 303 is installed at the bottom of the vertical rod 3022. A sealing cover 304 is installed at the bottom of the mounting cover 102. A filter screen 3044 is arranged at the top of the sealing cover 304. The sealing plate 303 is slidably arranged inside the sealing cover 304. A water outlet 3031 is formed on the sealing plate 303. A covering 3032 is arranged on the water outlet 3031. A second ejector post 306 is installed at the bottom of the mounting cover 102 corresponding vertically to the covering 3032. A first ejector post 3043 is installed at the bottom of the sealing cover 304 corresponding vertically to the covering 3032. An iron plate 3052 is installed on the covering 3032. A positioning bracket 305 is installed on the sealing plate 303. A magnet 3051 is installed on the positioning bracket 305, and the magnet 3051 corresponds vertically to the iron plate 3052. When the turntable 201 rotates, the position of the adjusting roller 301 on the turntable 201 changes. The guiding chute 302 on the adjusting roller 301 can drive the vertical rod 3022 to move up and down multiple times. And the sealing plate 303 at the bottom of the vertical rod 3022 slides vertically back and forth inside the sealing cover 304 synchronously. When the sealing plate 303 moves downward, the chamber space above the sealing plate 303 and the sealing cover 304 becomes larger. At this time, water flows inward and can carry a part of the broken ice to move towards one side of the sealing cover, ensuring that the floating ice outside the top plate 204 is removed. When the sealing plate 303 moves to the bottom, the first ejector post 3043 at the bottom can squeeze the covering 3032, so that the covering 3032 can be adsorbed on the magnet 3051, and then the water outlet is opened at this time. When the sealing plate 303 moves upward, the sealing plate 303 will not push the water to flow out from the filter screen 3044, ensuring that the floating ice will not float again. And when the sealing plate 303 moves to the highest point, at this time the second ejector post 306 squeezes the covering, and at this time the covering 3032 and the magnet 3051 are separated. And under the influence of gravity, at this time the covering 3032 covers the water outlet again. Repeating the above operations, finally the broken ice can be gathered outside the sealing cover 304, ensuring that when the top plate 204 is installed, it will not be affected by the floating ice, and ensuring that the overall equipment can be fixed more stably.

[0044] Such as Figures 1 to 10As shown, in the specific implementation, a countersunk groove 1023 is formed at the bottom of the mounting cover 102. The surface of the countersunk groove 1023 is connected to the outer shell of the driving motor 2011. One end of the side plate 2022 is provided with a slide bar 2021, and the slide bar 2021 is slidably arranged in the extrusion groove 202. The other end of the side plate 2022 is provided with a synchronous plate 2023, and the surface of the synchronous plate 2023 is connected to the synchronous rod 203. The driving motor 2011 arranged inside the countersunk groove 1023 drives the turntable 201 to rotate. A specific-shaped extrusion groove 202 is formed on the turntable 201. At this time, the position of the extrusion groove 202 changes, and the extrusion groove 202 can drive the internal slide bar 2021 to slide, and the positions of the side plate 2022 and the synchronous plate 2023 on the slide bar 2021 change.

[0045] As Figures 1 to 10 shown, further, a partition plate 1022 is movably inserted into the side wall of the synchronous rod 203. The partition plate 1022 is installed in the inner cavity of the positioning sleeve 1021. A slide plate 2031 is installed on the side wall of the synchronous rod 203. A positioning rod 2032 is installed through the inside of the slide plate 2031. One end of the positioning rod 2032 is connected to the side wall of the partition plate 1022, and the other end of the positioning rod 2032 is provided with a positioning plate 2034. The diameter of the positioning plate 2034 is larger than that of the positioning rod 2032. A positioning spring 2033 is sleeved on the side wall of the positioning rod 2032. One end of the positioning spring 2033 is clamped on the side wall of the slide plate 2031, and the other end is clamped on the partition plate 1022. The synchronous plate 2023 drives the synchronous rod 203 to slide on the partition plate 1022. The partition plate 1022 ensures the overall sealing of the device. At this time, the top plate 204 at the end of the synchronous rod 203 can drive the top plate 204 to move outwards, and the top plate 204 moves towards the periphery of the hole, so that the whole device can be positioned at the center of the hole. After the synchronous rod 203 moves, the slide plate 2031 on the side wall of the synchronous rod 203 can slide on the positioning rod 2032, and the positioning spring 2033 on the positioning rod 2032 is compressed synchronously. The positioning spring 2033 facilitates the later reset operation. A positioning plate 2034 is arranged at the end of the positioning rod 2032 to ensure that the slide plate 2031 and the positioning rod 2032 will not separate.

[0046] Example 2:

[0047] Based on the above example, the difference from this example is: As Figures 1 to 10As shown in the figure, a notch 2052 is provided inside the positioning sleeve 1021. The vibrating wire strain gauge housing 205 movably penetrates through the notch 2052. A limiting rod 2061 is movably inserted on the limiting block 206. A limiting spring 2062 is sleeved on the side wall of the limiting rod 2061. One end of the limiting spring 2062 is clamped on the inner wall of the positioning sleeve 1021, and the other end of the limiting spring 2062 is clamped on the side wall of the limiting block 206. A guiding rod 2063 is installed on the side wall of the limiting block 206. The guiding rod 2063 is slidably arranged in the descending groove 2064. The height of the connection between the descending groove 2064 and the shifting groove 2065 is lower than the height of the other end of the descending groove 2064, and the shifting groove 2065 is close to one side of the turntable 201. The shifting groove 2065 is a horizontal groove. When the synchronous rod 203 moves, the positions of the descending groove 2064 and the shifting groove 2065 on the synchronous rod 203 change. Among them, a guiding rod 2063 that can only move vertically is installed inside the descending groove 2064. Therefore, at this time, the guiding rod 2063 can drive the limiting block 206 to move downward. The limiting block 206 slides inside the limiting rod 2061, and the limiting spring 2062 on the limiting rod 2061 is stretched. The limiting spring 2062 facilitates the later reset operation. And the vibrating wire strain gauge housing 205 at the bottom of the limiting 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.

[0048] As Figures 1 to 10 shown, further, a knob 3011 is installed on the adjusting roller 301. The knob 3011 movably penetrates through the positioning cover 103. A handle 1031 is installed on the side wall of the positioning cover 103. An anti-slip sleeve is installed on the surface of the handle 1031. A connecting block 3012 is installed at the rotation center of the bottom of the adjusting roller 301. The end of the connecting block 3012 is connected to the rotation center of the turntable 201. 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 cannot work later, by rotating the knob 3011, the turntable 201 and the adjusting roller 301 are synchronously driven to rotate, which is convenient for the use of the device.

[0049] Example 3:

[0050] Based on the above embodiments, the difference from this embodiment is that as Figures 1 to 10As shown in the figure, a guiding sliding block 3021 is slidably arranged on the guiding sliding groove 302. A vertical rod 3022 is installed at the bottom of the guiding sliding block 3021, and the end of the vertical rod 3022 is installed at the end of the sealing cover 304. After the adjusting roller 301 rotates, the guiding sliding groove 302 on the adjusting roller 301 rotates. At this time, since the guiding sliding groove 302 is wavy and the guiding sliding block 3021 is slidably arranged inside the guiding sliding groove 302, the guiding sliding block 3021 can move up and down along the guiding sliding groove 302 multiple times. The guiding sliding block 3021 drives the vertical rod 3022 to move vertically up and down multiple times, and finally the sealing plate 303 at the bottom of the vertical rod 3022 can slide inside the sealing cover 304 multiple times.

[0051] As Figures 1 to 10 shown, in the specific implementation manner, a base 3041 is installed at the bottom of the sealing cover 304. A drain port 3042 is opened on the base 3041. The drain port 3042 corresponds to the water outlet 3031. A cross support is installed inside the drain port 3042, and a first top column 3043 is installed on the cross support. The size of the first top column 3043 is smaller than the size of the drain port 3042. An installation groove 3037 is opened on the sealing plate 303. A clamping rod 3034 is installed on the installation groove 3037. A pressing plate 3033 is movably inserted and installed on the side wall of the clamping rod 3034. The side wall of the pressing plate 3033 is connected to the sealing plate 303, and a sealing gasket is arranged at the bottom of the sealing plate 303. A clamping plate 3036 is installed at the top of the clamping rod 3034. A compression spring 3035 is sleeved on the clamping rod 3034 between the clamping plate 3036 and the pressing plate 3033. The two ends of the compression spring 3035 are respectively clamped on the pressing plate 3033 and the clamping plate 3036. The height of the top of the clamping rod 3034 is higher than the height of the positioning bracket 305. The first top column 3043 at the bottom of the base 3041 can squeeze the covering 3032, so that the pressing plate 3033 on the side wall of the covering 3032 moves along the clamping rod 3034, and the compression spring 3035 on the clamping rod 3034 is compressed synchronously. When the covering 3032 moves upward to a certain extent, the iron plate 3052 on the covering 3032 can be adsorbed on the magnet 3051 at this time, and then the water outlet 3031 is opened at this time, and the elastic force of the compression spring 3035 at this time is not enough to separate the iron plate 3052 and the magnet 3051.

[0052] The implementation principle of a polar sea ice stress buoy in this embodiment is as follows:

[0053] When the device needs to be used, the operator first opens a hole on the sea ice surface, then clears the large ice blocks in the opened hole, and then places the whole device in the hole, and ensures that the device can float through the floating cover.

[0054] Next, the operator starts the drive motor 2011. The drive motor 2011 arranged inside the countersunk head groove 1023 drives the turntable 201 to rotate. A pressing groove 202 with a specific shape is formed on the turntable 201. At this time, the position of the pressing groove 202 changes. The pressing groove 202 can drive the slide bar 2021 inside it to slide. The positions of the side plate 2022 and the synchronization plate 2023 on the slide bar 2021 change. The synchronization plate 2023 drives the synchronization rod 203 to slide on the partition plate 1022. The partition plate 1022 ensures the overall sealing of the device. At this time, the top plate 204 at the end of the synchronization rod 203 can drive the top plate 204 to move outwards. The top plate 204 moves towards the periphery of the hole, so that the whole device can be positioned at the center of the hole.

[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. The positioning spring 2033 facilitates the later reset operation. A positioning plate 2034 is arranged 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. A guiding rod 2063 that can only move vertically is installed inside the descending groove 2064. At this time, the guiding rod 2063 can drive the limiting block 206 to move downwards. The limiting block 206 slides inside the limiting rod 2061, and the limiting spring 2062 on the limiting rod 2061 is stretched. The limiting spring 2062 facilitates the later reset operation. The vibrating wire type strain gauge housing 205 at the bottom of the limiting block 206 can move downwards to ensure that the detection contact 2051 on the vibrating wire type strain gauge housing 205 can move to the designated position. When icing occurs later, the detection contact 2051 contacts the ice layer, and then the stress is detected through the detection contact 2051. The detection principle of the detection contact 2051 is prior art and will not be elaborated 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 drive motor 2011 cannot work later, by rotating the knob 3011, the turntable 201 and the adjusting roller 301 are rotated synchronously, which facilitates the use of the device.

[0058] After the adjusting roller 301 rotates, the guiding chute 302 on the adjusting roller 301 rotates. At this time, since the guiding chute 302 is wavy and a guiding slider 3021 is slidably arranged inside the guiding chute 302, the guiding slider 3021 can move up and down along the guiding chute 302 multiple times, and the guiding slider 3021 drives the vertical rod 3022 to move vertically up and down multiple times. Eventually, 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 chamber space above the sealing plate 303 and the sealing cover 304 becomes larger. At this time, water flows inward and can carry a part of the broken ice to move toward one side of the sealing cover 304. The broken ice is blocked around the filter screen 3044, and due to the movement of the broken ice position, the floating ice outside 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 ejector pin 3043 at the bottom of the base 3041 can squeeze the cover 3032, so that the pressing 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. At this time, the water outlet 3031 is opened, and the elastic force of the compression spring 3035 at this time 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 at this time does not push the water to flow out from the filter screen 3044. The water can be discharged along the water outlet 3031, ensuring that the floating ice will not spread to various positions again. And when the sealing plate 303 moves to the highest point, the second ejector pin 306 squeezes the cover 3032 at this time. At this time, 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. Repeating the above operations, the broken ice can be finally gathered outside the sealing cover 304, ensuring that when the top plate 204 is installed, it will not be affected by the floating ice, ensuring that the overall equipment can be fixed more stably and making the stress detection accuracy higher.
