Description

Technical Field

[0001] This invention relates to the field of sea ice thickness measurement, specifically to a sea ice thickness measurement device based on an icebreaker. Background Technology

[0002] Sea ice thickness is a core parameter for polar scientific research, safety assessment of ice-covered waterways, marine environmental monitoring, and marine resource development. Precise and efficient sea ice thickness measurement technology plays an irreplaceable supporting role in the accumulation of polar climate research data, navigation route planning for northern coastal waterways, safety protection for maritime operations, and emergency rescue deployment. Icebreakers, as the core carriers capable of operating deep into polar and high-latitude ice-covered waters, have become the optimal choice for carrying sea ice thickness measurement equipment due to their unique advantages in breaking sea ice. With the deepening of polar exploration activities and the rapid development of coastal shipping, the industry has placed higher demands on the accuracy, real-time performance, environmental adaptability, and automation of sea ice thickness measurement. Intelligent sensor technology, with its functions of automatic data acquisition, signal preprocessing, and adaptive adjustment under operating conditions, is gradually being applied to sea ice thickness measurement equipment to improve the level of measurement automation and data accuracy. Therefore, a sea ice thickness measurement device is needed to facilitate the measurement and processing of sea ice thickness.

[0003] The sensor probes of existing sea ice thickness measurement equipment are mostly exposed outside the hull. During measurement operations, they are easily entangled and impacted by ice debris. This not only causes physical damage to the probes but also directly leads to interruption or distortion of measurement signal transmission, seriously affecting the continuity of measurement work and the reliability of the original data. At the same time, in contact measurement scenarios, the ice surface is often covered with a snow layer, and acoustic measurement technology has difficulty in effectively distinguishing between the ice layer and the snow layer. It is easy to include the snow thickness in the sea ice thickness measurement results, resulting in systematic deviations in the final ice thickness data and affecting the accuracy of data interpretation.

[0008] Preferably, the extended closing frame has two internally mounted slide rails fixedly connected inside, and two position control motors fixedly connected inside. Both position control motors are electrically connected to an external control component. The extended closing frame has two displacement screws rotatably connected inside, and both displacement screws are fixedly connected to the motor shafts of the corresponding position control motors.

[0009] Preferably, both micro-movement sliders are slidably connected inside the extended closing frame, both micro-movement sliders are provided with threaded through holes that cooperate with the corresponding displacement screws, both micro-movement sliders are slidably connected to the corresponding internal slide rails, and both mounting blocks are provided with cylindrical blocks.

[0010] Preferably, a torsion motor is fixedly connected to each of the two mounting blocks, and both torsion motors are electrically connected to an external control component. A tilting torsion frame is rotatably connected between the two mounting blocks, and the tilting torsion frame is fixedly connected to the two torsion motors. A downward moving cylinder is fixedly connected to the tilting torsion frame, and the downward moving cylinder is electrically connected to an external control component.

[0011] Preferably, the lifting slide is slidably connected inside the tilting frame, the tilting frame has a docking hole, the docking cylinder is fixedly inserted into the docking hole of the lifting slide, and the docking cylinder has an inner rotating groove inside.

[0012] Preferably, the bottom of the lifting slide is fixedly connected to four stabilizing springs, the bottom of the lifting slide is fixedly connected to a fixed outer frame, a drive motor is fixedly connected inside the fixed outer frame, the drive motor is electrically connected to an external control component, and a drive gear is fixedly connected to the motor shaft of the drive motor.

[0014] Preferably, the bottom of the snow removal chassis is fixedly connected to six scrapers arranged in a circular pattern, the bottom of the rotating inner rod is fixedly connected to a mounting base, the bottom of the mounting base is fixedly connected to three ice-touching probes arranged in a circular pattern, all three ice-touching probes are electrically connected to an external control component, and the ice thickness measuring device is electrically connected to the external control component.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The ice thickness measuring device is fixed to the bottom of the extended push block. Under normal conditions, it is retracted into the inner groove of the rotating inner rod along with the extended push block. The inner groove forms a closed protective space, which can effectively isolate the probe from the erosion and impact of ice chips, seawater, and debris during navigation, avoiding physical damage to the probe. During measurement, the extended push block is driven by the inner push cylinder to extend the ice thickness measuring device for operation. After the measurement is completed, it is quickly retracted, greatly shortening the probe exposure time and reducing the risk of damage. At the same time, the extended part is guided by the docking groove and the inner block, and the stabilizing base block and the stabilizing groove. The micro-movement part is guided by the inner slide rail and the micro-movement part. The sliding engagement of the slider ensures precise and stable movement of all components, avoiding measurement deviations caused by device wobbling during operation. The torsion motor drives the rotating torsion frame to adjust the angle of the measuring section, adapting to the measurement needs of ice layers in different orientations. It can be installed and used without modifying the hull, making it highly adaptable. This effectively avoids the problem of sensor probes being exposed on the outside of the hull, which are easily entangled and impacted by ice debris during measurement operations. This not only causes physical damage to the probes but also directly leads to interruption or distortion of measurement signal transmission, seriously affecting the continuity of measurement work and the reliability of the original data.

[0016] 2. The measurement unit is equipped with a snow-clearing chassis, with six circumferentially distributed scrapers fixed to its bottom. During operation, a drive motor rotates the drive gear, which in turn drives the rotating inner rod and the snow-clearing chassis to rotate. The scrapers quickly clear the snow layer and floating ice debris from the area to be measured, completely exposing the ice surface and physically eliminating the interference of the snow layer on the measurement. Three circumferentially distributed ice-contact probes fixed to the bottom of the rotating inner rod can accurately detect the position of the ice surface after snow removal. When the probes contact the ice layer, they immediately send a signal to the external control components to control the lowering cylinder to stop descending. This ensures that the ice thickness measuring instrument only measures the thickness from the ice surface and does not include the snow layer thickness in the measurement results. This effectively avoids the problem in contact measurement scenarios where the ice surface is often covered by a snow layer. It is difficult to effectively distinguish between the ice layer and the snow layer using intelligent sensors and acoustic measurement technology, which can easily include the snow thickness in the sea ice thickness measurement results, leading to a systematic deviation in the final ice thickness data and affecting the accuracy of data interpretation.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1 - Figure 13An ice thickness measuring device based on an icebreaker includes an installation part 1. The installation part 1 has an extension part 2 inside, which includes an extension closing frame 201 slidably connected to the interior of the installation hull 101. The extension part 2 also has a micro-movement part 3 inside, including two micro-movement sliders 301. Each of the two micro-movement sliders 301 has a mounting block 302 fixedly connected to its top. The micro-movement part 3 also has a lifting part 4 inside, including a lifting slide 401. A docking cylinder 402 is fixedly connected to the bottom of the lifting slide 401. The lifting part 4 also has a measuring part 5 inside, including a rotating inner rod 501. An inner groove 502 is opened inside the rotating inner rod 501, and an extension pusher 504 is slidably connected inside the inner groove 502. A snow-clearing chassis 505 is fixedly connected to the bottom of the rotating inner rod 501, and an ice thickness measuring device 508 is fixedly connected to the bottom of the extension pusher 504.

[0021] The installation unit 1 includes an installation hull 101, which is part of the icebreaker. The bottom of the installation hull 101 is provided with a stabilizing groove 102. Two inner fitting blocks 103 are fixedly connected to the inner wall of the installation hull 101, and each of the two inner fitting blocks 103 is provided with a threaded through hole.

[0022] The extended closing frame 201 has two docking grooves 202, and each of the two docking grooves 202 has a corresponding inner fitting block 103 slidably connected inside. The bottom of the extended closing frame 201 is fixedly connected to a stabilizing block 203, which is slidably connected inside the stabilizing groove 102. The extended closing frame 201 has two extended motors 204 fixedly connected inside, and both extended motors 204 are electrically connected to an external control component. The extended closing frame 201 has two extended screws 205 rotatably connected inside, and both extended screws 205 are fixedly connected to the motor shaft of the corresponding extended motor 204. Both extended screws 205 are threadedly connected to the corresponding inner fitting block 103.

[0023] The extended closing frame 201 has two internally mounted slide rails 206 fixedly connected inside, and two position control motors 207 fixedly connected inside. Both position control motors 207 are electrically connected to the external control components. The extended closing frame 201 has two displacement screws 208 rotatably connected inside, and both displacement screws 208 are fixedly connected to the motor shafts of the corresponding position control motors 207.

[0024] Both micro-movement sliders 301 are slidably connected inside the extended closing frame 201. Both micro-movement sliders 301 are provided with threaded through holes that cooperate with the corresponding displacement screws 208. Both micro-movement sliders 301 are slidably connected to the corresponding internal slide rails 206. Both mounting blocks 302 are provided with cylindrical blocks.

[0025] A torsion motor 303 is fixedly connected to each of the two mounting blocks 302. Both torsion motors 303 are electrically connected to an external control component. A tilting torsion frame 304 is rotatably connected between the two mounting blocks 302. The tilting torsion frame 304 is fixedly connected to the two torsion motors 303. A lowering cylinder 305 is fixedly connected to the tilting torsion frame 304. The lowering cylinder 305 is electrically connected to an external control component.

[0026] In this embodiment, when the measuring component needs to be extended outside the hull for measurement, the external control component activates the extension motor 204. The extension motor 204 drives the extension screw 205 to rotate. Utilizing the threaded transmission between the extension screw 205 and the inner block 103, the extension closing frame 201 is driven to extend outward along the guide direction of the inner block 103 and the stabilizing groove 102. After the measurement is completed, the extension motor 204 rotates in the opposite direction, driving the extension closing frame 201 back into the mounting hull 101. When it is necessary to adjust the horizontal position of the measuring part 5 to align with the ice surface area to be measured, the external control component activates the position control motor 207. The position control motor 207 drives... The displacement screw 208 rotates, driving the micro-movement slider 301 to move horizontally within a small range along the inner slide rail 206 via the threaded transmission between the displacement screw 208 and the micro-movement slider 301, thus achieving precise fine-tuning of the measurement position. When there is ice to be measured on the side of the icebreaker, or when the measurement angle needs to be adjusted, the external control component activates the torsion motor 303. The torsion motor 303 drives the tilting torsion frame 304 to rotate, thereby achieving the angle tilting of the lifting part 4 and the measuring part 5 to meet the measurement needs of different orientations. At the same time, the external locking component keeps the lifting part 4 and the measuring part 5 at the predetermined measurement angle, and the ice thickness measuring instrument 508 is fixed to the extended push block 50. 4. At the bottom, under normal conditions, the extended push block 504 is retracted into the inner groove 502 of the rotating inner rod 501. The inner groove 502 forms a closed protective space, which can effectively isolate the probe from the erosion and impact of ice chips, seawater and debris during navigation, and avoid physical damage to the probe. During measurement, the extended push block 504 is driven by the inner push cylinder 503 to extend the ice thickness measuring instrument 508 for operation. After the measurement is completed, it is quickly retracted, which greatly shortens the time the probe is exposed and reduces the risk of damage. At the same time, the extended part 2 is guided by the docking groove 202 and the inner matching block 103, and the stabilizing bottom block 203 and the stabilizing groove 102. The micro-moving part 3 is guided by the inner... The sliding engagement between the slide rail 206 and the micro-movement slider 301 ensures precise and stable movement of each component, avoiding measurement deviations caused by device shaking during operation. The torsion motor 303 drives the rotating torsion frame 304 to rotate, enabling 5-angle adjustment of the measuring unit to adapt to the measurement needs of ice layers in different orientations. It can be installed and used without modifying the hull, making it highly adaptable. This effectively avoids the problem of sensor probes being exposed on the outside of the hull, which are easily entangled and impacted by ice debris during measurement operations. This not only causes physical damage to the probes but also directly leads to interruption or distortion of measurement signal transmission, seriously affecting the continuity of measurement work and the original reliability of the data.

[0027] Example 2: Please refer to Figure 1 - Figure 13 The lifting slide 401 is slidably connected to the inside of the flipping torsion frame 304. The flipping torsion frame 304 is provided with a docking hole. The docking cylinder 402 is fixedly inserted into the docking hole of the lifting slide 401. The inside of the docking cylinder 402 is provided with an inner rotating groove 403.

[0028] Four stabilizing springs 404 are fixed to the bottom of the lifting slide 401. A fixed outer frame 405 is fixed to the bottom of the lifting slide 401. A drive motor 406 is fixed inside the fixed outer frame 405. The drive motor 406 is electrically connected to the external control components. A drive gear 407 is fixed to the motor shaft of the drive motor 406.

[0029] The rotating inner rod 501 is rotatably connected in the inner rotating groove 403. The top of the rotating inner rod 501 is provided with a locking tooth for cooperating with the drive gear 407. The inner push cylinder 503 is fixedly connected inside the inner groove 502. The inner push cylinder 503 is electrically connected to the external control component. The bottom of the outward push block 504 is provided with a docking slot.

[0030] The bottom of the snow removal chassis 505 is fixed with six scrapers arranged in a circle. The bottom of the rotating inner rod 501 is fixed with a mounting chassis 506. The bottom of the mounting chassis 506 is fixed with three ice-touching probes 507 arranged in a circle. All three ice-touching probes 507 are electrically connected to the external control components. The ice thickness measuring device 508 is electrically connected to the external control components.

[0031] In this embodiment, when the measuring unit 5 needs to be lowered to the ice surface, the lowering cylinder 305 is activated, pushing the lifting slide 401 to move the measuring unit 5 downward along the flipping torsion frame 304. When the measuring unit 5 is lowered above the ice surface, the external control component activates the drive motor 406. The drive motor 406 drives the drive gear 407 to rotate, which in turn drives the rotating inner rod 501 to rotate, thereby driving the snow-clearing chassis 505 and the scraper to rotate. The scraper cleans the snow and floating ice on the ice surface, ensuring that the ice thickness measuring instrument 508 can directly contact the ice surface, improving measurement accuracy. After the snow-clearing chassis 505 has cleaned the ice surface... The lifting unit 4 continues to drive the measuring unit 5 downwards. When the ice-touching probe 507 contacts the ice surface, it sends a signal to the external control component. The external control component then controls the lowering cylinder 305 to stop descending, ensuring the measuring unit 5 is in the optimal measuring position. After the ice-touching probe 507 sends a signal indicating contact with the ice, the external control component activates the inner push cylinder 503. The inner push cylinder 503 pushes the outer push block 504 downwards along the inner groove 502, causing the ice thickness measuring device 508 to move downwards. The ice thickness measuring device 508 collects ice thickness data in real time and transmits the data to the external control component, completing the ice thickness measurement. After measurement, the inner cylinder 503 retracts, causing the ice thickness measuring device 508 to retract into the inner slot 502. Then, all components reset sequentially, awaiting the next measurement. The measuring unit 5 is equipped with a snow-clearing chassis 505, with six circumferentially distributed scrapers fixed to its bottom. During operation, the drive motor 406 drives the drive gear 407 to rotate, which in turn drives the rotating inner rod 501 and the snow-clearing chassis 505 to rotate. The scrapers quickly clear the snow layer and floating ice debris from the area to be measured, completely exposing the ice surface and physically eliminating the interference of the snow layer on the measurement. The three circumferentially distributed scrapers fixed to the bottom of the rotating inner rod 501... The ice-contact probe 507 can accurately detect the position of the ice surface after snow removal. When the probe contacts the ice, it immediately sends a signal to the external control components to control the lowering cylinder 305 to stop descending. This ensures that the ice thickness measuring device 508 only measures the thickness from the ice surface and does not include the snow layer thickness in the measurement result. This effectively avoids the problem that in contact measurement scenarios, the ice surface is often covered by a snow layer, and it is difficult to effectively distinguish between the ice layer and the snow layer using intelligent sensors and acoustic measurement technology. This can easily lead to the inclusion of snow thickness in the sea ice thickness measurement result, resulting in a systematic deviation in the final ice thickness data and affecting the accuracy of data interpretation.
