Description

Technical Field

[0001] This invention relates to the technical field of snow moisture content detection in polar environments, and particularly to a device and method for detecting snow moisture content in polar environments. Background Technology

[0002] In polar environments, the water content of snow cover is of great significance for climate change, glacier melting, and water resource management. Climate change in polar regions has a significant impact on the global climate system, and snow cover water content is one of the important indicators of climate change. Monitoring snow cover water content can help researchers understand information such as precipitation and snowmelt rate in polar regions, providing data support for climate research. Monitoring snow cover water content is also of great significance for water resource management and natural disaster early warning.

[0003] To facilitate snow sampling, patent application CN118150506B discloses a device and method for detecting snow moisture content in polar environments. The device consists of a detection device, a sampling device, and a rotating component. Although the device can perform sampling and detection operations, in actual use, the detection device, sampling device, and rotating component all need to be installed on a tracked mobile device. However, due to its large size, it is not convenient to disassemble and assemble, which means that the tracked mobile device can only be used for this purpose. At the same time, due to its size, more materials are used, and the corresponding production cost also increases. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this invention is to provide a device and method for detecting the water content of snow in polar environments. With its compact size, this device is easy to transport and carry, while reducing production costs. Its innovative wall-mounted design allows the device to be quickly and easily installed or removed from an external testing vehicle, which not only significantly improves the efficiency of installation and removal, but also greatly enhances the flexibility and efficiency of the testing vehicle, bringing users a better user experience.

[0006] To achieve the above objectives, this invention proposes a device for detecting the water content of snow in polar environments, including a wall-mounted detection device, wherein the wall-mounted detection device comprises:

[0008] Snow collection assembly: includes a sliding base and a snow blocking plate. The sliding base is vertically slidably connected to the surface of the upper shell and is driven by a screw lifting mechanism located inside the upper shell to achieve vertical lifting. A snow collection tube is threadedly connected to the inner wall of the end located outside the upper shell and corresponds to the position of the first opening slot. A toothed plate is fixedly connected to the surface of the end located inside the upper shell. The snow blocking plate is fixedly connected to the surface of the upper shell, and one end of the plate penetrates into the interior of the snow collection tube and is slidably connected to the inner wall of the snow collection tube.

[0009] Snow melting bearing rotary cutting assembly: includes a switching turntable, a bearing tube, a constant temperature heating plate and a drive seat. The switching turntable is rotatably connected to the inner wall of the lower shell, and its surface is alternately provided with a second opening groove and a bearing tube. The constant temperature heating plate is symmetrically fixedly connected to the inner wall of the lower shell and is slidably connected to the top and bottom of the bearing tube respectively. The drive seat is located at the top of the lower shell and inside the upper shell. The drive seat is connected to the toothed plate and the switching turntable respectively.

[0010] Controller: Located on the top of the upper shell, it is connected to the vehicle power supply, the lead screw lifting mechanism, the constant temperature heating plate and the external remote control handle through data interfaces.

[0011] In addition, the polar environment snow layer moisture content detection device proposed above may also have the following additional technical features:

[0012] Specifically, the bottom of the snow collection tube is an open structure, and a strip groove is opened on the surface of the snow collection tube corresponding to the position of the snow baffle plate. One end of the strip groove extends to the bottom of the snow collection tube, and one end of the snow baffle plate passes through the strip groove into the interior of the snow collection tube. The end of the snow baffle plate that passes through the interior of the snow collection tube is disc-shaped and is adapted to the internal size of the snow collection tube.

[0013] Specifically, the outer diameter of the snow collection tube is smaller than the inner diameter of the second opening groove and the supporting pipe, the outer diameter of the second opening groove and the supporting pipe is smaller than the inner diameter of the first opening groove, and the snow collection tube, the first opening groove, the second opening groove and the supporting pipe are on the same axis.

[0014] Specifically, the number of the second opening grooves is equal to the number of the supporting pipes, and both the number of the second opening grooves and the number of supporting pipes are set to an even number.

[0015] Specifically, the carrier tube includes a glass tube body, an upper heat-conducting seat, and a lower sealing heat-conducting seat. The glass tube body is bonded and fixed to the inner wall of the switching turntable. The upper heat-conducting seat and the lower sealing heat-conducting seat are respectively snapped and fixed to the top and bottom of the glass tube body. A through groove is opened on the surface of the upper heat-conducting seat. The two sets of constant temperature heating plates are slidably connected to the top of the upper heat-conducting seat and the bottom of the lower sealing heat-conducting seat, respectively.

[0016] Specifically, the glass tube surface is provided with scale lines, the switching turntable surface is provided with an observation port corresponding to the position of the glass tube, and the lower shell surface is snapped and fixed with an observation window corresponding to the position of the switching turntable.

[0017] Specifically, the constant temperature heating plate is C-shaped, and the notch of the constant temperature heating plate corresponds to the position of the first opening groove.

[0018] Specifically, the drive seat includes a seat body, a transmission shaft, a worm gear, a drive gear, a worm, a driven gear, a driving gear, a side gear, and a one-way transmission device. The seat body is fixedly connected to the top of the lower shell and located inside the upper shell. The transmission shaft is rotatably connected to the inner wall of the seat body. One end of the transmission shaft is fixedly connected to the worm gear, and the other end of the transmission shaft penetrates into the lower shell and is fixedly connected to the drive gear. The drive gear is located on the driven gear side of the central shaft end surface of the switching turntable and meshes with it. The worm is rotatably connected to the inner wall of the seat body and meshes with the worm gear. The driven gear is fixedly connected to one end surface of the worm. The driving gear is rotatably connected to the inner wall of the seat body and meshes with the driven gear. The side gear is rotatably connected to the inner wall of the seat body and is connected to the driving gear by the one-way transmission device. One end of the side gear penetrates out of the seat body and is located on one side of the toothed plate. The side gear meshes with the teeth on the toothed plate surface.

[0019] A method for using a polar environment snow layer moisture content detection device, applied to the above-mentioned polar environment snow layer moisture content detection device, includes the following steps:

[0020] S1: Install the wall-mounted detection device at a preset position on the surface of the external detection vehicle, and then connect it to the vehicle's power supply;

[0021] S2: After the connection is completed, the device is brought to the snow layer detection point by the external detection vehicle. The operator sends the detection command to the controller through the external remote control handle in the cab. After receiving the command, the controller controls the constant temperature heating plate and the screw lifting mechanism to operate in sequence according to the command.

[0022] S3: After the constant temperature heating plate starts operating, it generates heat and ensures that the temperature is always at the preset temperature. The screw lifting mechanism first drives the slide to descend, and the descent of the slide simultaneously drives the snow collection tube and the toothed plate to descend. During the descent, the snow collection tube passes through the first and second opening slots and inserts into the snow layer to sample the snow. Then, the screw lifting mechanism continues to operate, and simultaneously drives the snow collection tube and the toothed plate to rise. When the bottom of the snow collection tube moves to the top side of the first opening slot, the toothed plate triggers the drive seat to operate. The drive seat drives the switching turntable to rotate at a set angle, realizing the switching of the second opening slot and the position of the carrying tube. As the snow collection tube continues to rise, the snow sample inside the snow collection tube will fall into the carrying tube for collection under the obstruction of the snow baffle. With the next step of repeating the sampling operation, the position of the carrying tube is switched. It enters the lower shell from the first opening slot and comes into contact with the constant temperature heating plate. The snow sample inside the carrying tube is melted by the principle of heat conduction. After the snow sample melts, the amount of water inside the carrying tube can be directly observed through the observation window.

[0023] S4: Repeat the above operation to perform multiple snow sample collection operations until all the carrier tubes have been used.

[0024] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] With its compact size, this device is easy to transport and carry, while reducing production costs. Its innovative wall-mounted design allows the device to be quickly and easily installed or removed from the external inspection vehicle, which not only significantly improves the efficiency of installation and removal, but also greatly enhances the flexibility and efficiency of the inspection vehicle, bringing users a better user experience.

[0027] This device features a meticulously designed mounting housing that is compact and uses minimal materials, facilitating transportation and handling while effectively reducing production costs. The housing cleverly comprises an upper shell, a lower shell, and a plate. The lower shell has a specially designed first opening groove on its surface, while the plate is securely mounted on the external inspection vehicle, serving as the stable foundation of the entire inspection system. During assembly and disassembly, users only need to easily connect and separate the plate from the external inspection vehicle, greatly improving the efficiency of the disassembly and assembly process. The upper and lower shells are securely fixed to the plate surface through a convenient interlocking mechanism, forming a robust protective barrier that provides comprehensive protection for internal components and ensures easy and convenient installation and disassembly. Furthermore, the modular design of the device makes rapid maintenance easy and significantly reduces replacement costs. Particularly noteworthy is the perfectly designed first opening groove on the lower shell surface, specifically tailored for the snow collection tube in the snow collection component, ensuring smooth entry and exit of the snow collection tube and greatly enhancing the device's performance.

[0028] This device ingeniously integrates a snow collection assembly, which consists of key components such as a sliding base, snow baffle plate, screw lifting mechanism, snow collection tube, and toothed plate. The sliding base is vertically slidably connected to the upper shell surface and precisely driven by the screw lifting mechanism, enabling flexible up-and-down movement of the snow collection tube. The snow collection tube is fixed to the inner wall of one end of the sliding base via a threaded connection, specifically designed for precise sampling from the snow layer. The snow baffle plate is securely mounted on the upper shell surface, with one end cleverly penetrating into the snow collection tube. Its unique design lies in the fact that when the snow collection tube rises, the snow baffle plate... The snowboard effectively blocks the columnar snow sample inside the snow collection tube, allowing it to fall naturally into the pre-set carrying tube under gravity, thus easily collecting the snow sample. In addition, the toothed plate is fixedly connected to the other end surface of the slide. This design is cleverly connected to the drive seat in the snow melting carrying rotary cutting component, realizing seamless power transmission. It is particularly worth mentioning that the entire sampling operation and switching operation are driven by a single power source. This innovative design not only greatly simplifies the operation process and improves the convenience of control, but also effectively reduces production costs.

[0029] This device innovatively features a snow melting support rotary cutting assembly, which consists of three core components: a switching turntable, a constant-temperature heating plate, and a drive base. The switching turntable is ingeniously designed with a second opening slot and a support tube, which are alternately distributed on the turntable. By rotating the switching turntable, the second opening slot and the support tube can be flexibly switched back and forth. This design cleverly realizes the function of multiple collection and storage of snow samples. Compared with the traditional method, this switching design significantly reduces useless transportation time, thereby greatly improving the detection efficiency. The constant-temperature heating plate is another highlight of the assembly. Its compact design occupies very little space. Compared with the existing technology, the constant-temperature heating plate in this device is not only more advantageous in terms of production cost, but also performs excellently in terms of usage. It can stably provide the required temperature environment, ensuring the consistency and accuracy of snow samples during the melting process.

[0030] This device is equipped with a controller that connects to an external remote control via a data interface, allowing operators to perform sampling operations from inside the vehicle without having to get out, avoiding the cold and wind, and providing good results.

The surface of the lower housing 12 is provided with a first opening groove 14.

[0052] Snow collection component 2: includes a sliding base 21 and a snow baffle 23.

[0053] Snow melting bearing rotary cutting assembly 3: includes a switching turntable 31, a bearing tube 32, a constant temperature heating plate 33 and a drive seat 34. The switching turntable 31 is rotatably connected to the inner wall of the lower shell 12, and its surface is alternately provided with a second opening groove 311 and a bearing tube 32. The constant temperature heating plate 33 is symmetrically fixedly connected to the inner wall of the lower shell 12 and is slidably connected to the top and bottom of the bearing tube 32 respectively. The drive seat 34 is located at the top of the lower shell 12 and inside the upper shell 11. The drive seat 34 is connected to the toothed plate 24 and the switching turntable 31 respectively.

[0054] Controller 4: Located on the top of the upper shell 11, it is connected to the vehicle power supply, the lead screw lifting mechanism 25, the constant temperature heating plate 33 and the external remote control handle through the data interface.

[0055] It should be noted that the screw lifting mechanism 25 described in this embodiment includes a drive reducer, an encoder and a reciprocating screw, and the slide 21 is threadedly connected to the outer surface of the reciprocating screw and slidably connected to the surface of the upper shell 11.

[0056] It should also be noted that the external detection vehicle body, vehicle power supply, data interface and external remote control handle are not shown in the figure.

[0057] Specifically, this device, with its compact size, achieves convenient transportation and portability while reducing production costs. Its innovative wall-mounted design allows for quick and easy installation and removal from external inspection vehicles, significantly improving assembly and disassembly efficiency and greatly enhancing the flexibility and efficiency of the inspection vehicle, providing users with a superior experience. The device features a meticulously designed mounting housing 1, which is compact and uses minimal materials, facilitating transportation and handling while effectively reducing production costs. The mounting housing 1 cleverly comprises three parts: an upper shell 11, a lower shell 12, and a plate 13. The lower shell 12 has a specially designed first opening groove 14 on its surface, while the plate 13 is securely mounted on the external inspection vehicle, serving as a stable foundation for the entire inspection system. When using this device, the user only needs to easily connect and separate the plate 13 from the external inspection vehicle. This design greatly improves the efficiency of disassembly and assembly. The upper shell 11 and the lower shell 12 are securely fixed to the surface of the plate 13 through a convenient upper and lower sleeve method, forming a solid protective barrier. This provides comprehensive protection for the internal components and ensures easy and convenient installation and disassembly. In addition, the modular design concept of the device makes subsequent rapid maintenance easy and significantly reduces replacement costs. It is particularly worth mentioning that the first opening groove 14 on the surface of the lower shell 12 is designed perfectly. It is custom-made for the snow collection tube 22 in the snow collection component 2, ensuring that the snow collection tube 22 can enter and exit smoothly, thereby greatly improving the effectiveness of the device.This device ingeniously integrates a snow-collecting assembly 2, which consists of key components such as a sliding base 21, a snow-blocking plate 23, a screw-lifting mechanism 25, a snow-collecting tube 22, and a toothed plate 24. The sliding base 21 is vertically slidably connected to the surface of the upper shell 11 and precisely driven by the screw-lifting mechanism 25, thereby enabling the flexible up-and-down movement of the snow-collecting tube 22. The snow-collecting tube 22 is fixed to the inner wall of one end of the sliding base 21 via a threaded connection, specifically designed for precise sampling from the snow layer. The snow-blocking plate 23 is securely mounted on the surface of the upper shell 11, with one end cleverly penetrating into the interior of the snow-collecting tube 22. The unique design lies in the fact that when the snow collection tube 22 rises, the snow baffle 23 effectively blocks the columnar snow sample inside the tube 22, allowing it to fall naturally into the pre-set carrying tube 32 under gravity, thus easily collecting the snow sample. Furthermore, the toothed plate 24 is fixedly connected to the other end surface of the slide block 21. This design cleverly connects with the drive seat 34 in the snow melting carrying rotary cutting assembly 3, achieving seamless power transmission. Particularly noteworthy is that the entire sampling and switching operation is driven by a single power source. This innovative design not only greatly simplifies the operation process but also improves control... To enhance convenience and effectively reduce production costs, this device innovatively features a snow melting support rotary cutting assembly 3. This assembly consists of three core components: a switching turntable 31, a constant-temperature heating plate 33, and a drive base 34. The switching turntable 31 is meticulously designed with a second opening slot 311 and a support tube 32, which are alternately distributed on the turntable. By rotating the switching turntable 31, the second opening slot 311 and the support tube 32 can be flexibly switched back and forth. This design cleverly achieves multiple collection and storage of snow samples. Compared to traditional methods, this switching design significantly reduces unnecessary costs. By reducing transportation time, the detection efficiency is significantly improved. The constant-temperature heating plate 33, another highlight of the component, has a compact design and occupies minimal space. Compared with existing technologies, the constant-temperature heating plate 33 in this device not only has a greater advantage in production cost but also performs excellently in use. It can stably provide the required temperature environment, ensuring the consistency and accuracy of snow samples during the melting process. The device is equipped with a controller 4, which connects to an external remote control handle via a data interface, allowing operators to perform sampling operations inside the vehicle without leaving the vehicle, avoiding exposure to cold winds, and achieving good results.

[0058] In one embodiment of the present invention, such as Figure 3 As shown, the bottom of the snow collection tube 22 is an open structure. A strip groove 221 is provided on the surface of the snow collection tube 22 at the position corresponding to the snow baffle plate 23. One end of the strip groove 221 extends to the bottom of the snow collection tube 22. One end of the snow baffle plate 23 passes through the strip groove 221 and enters the interior of the snow collection tube 22. The end of the snow baffle plate 23 that enters the interior of the snow collection tube 22 is disc-shaped and is adapted to the internal size of the snow collection tube 22.

[0059] It should be noted that the snow barrier 23 described in this embodiment is detachably mounted on the surface of the upper shell 11, allowing for free position adjustment.

[0060] Specifically, this section mainly describes the design details of the snow collection tube 22 and the snow baffle 23. The bottom of the snow collection tube 22 is designed as an open structure, meaning that its bottom is open, allowing for convenient collection or release of snow samples. On the surface of the snow collection tube 22, there is a strip groove 221 corresponding to the position of the snow baffle 23. One end of this strip groove 221 extends to the bottom of the snow collection tube 22, providing a channel for the snow baffle 23 to pass through the strip groove 221 from the outside and enter the interior of the snow collection tube 22. One end of the snow baffle 23 passes through the wall of the snow collection tube 22 via the strip groove 221 and enters the interior of the snow collection tube 22. The end of the snow baffle 23 that enters the interior of the snow collection tube 22 is designed to be disc-shaped. This shape allows it to match the internal dimensions of the snow collection tube 22, thereby effectively preventing snow from moving. The snow baffle 23 is used to prevent the movement of snow, while the snow collection tube 22 is used to collect and store snow. By adjusting the position of the snow baffle 23 inside the snow collection tube 22, the snow sample can be controlled to meet different operational needs, resulting in good performance.

[0061] In one embodiment of the present invention, such as Figures 1-5 As shown, the outer diameter of the snow tube 22 is smaller than the inner diameter of the second opening groove 311 and the bearing tube 32, and the outer diameter of the second opening groove 311 and the bearing tube 32 is smaller than the inner diameter of the first opening groove 14. The snow tube 22, the first opening groove 14, the second opening groove 311 and the bearing tube 32 are on the same axis.

[0062] Specifically, the outer diameter of the snow collection tube 22 is carefully designed to be smaller than the inner diameter of the second opening slot 311 and the carrying tube 32, ensuring that the snow collection tube 22 can smoothly pass through the second opening slot 311 and that the snow sample can fall smoothly into the carrying tube 32. The outer diameters of the second opening slot 311 and the carrying tube 32 are also set to be smaller than the inner diameter of the first opening slot 14, which means that they can easily be placed in the first opening slot 14 without interference. It is worth noting that the snow collection tube 22, the first opening slot 14, the second opening slot 311 and the carrying tube 32 all cleverly share the same axis. This precise alignment design not only ensures smooth cooperation between the components, but also improves the stability of the overall structure and the accuracy of operation.

[0063] In one embodiment of the present invention, such as Figure 5 As shown, the number of second opening slots 311 and the number of supporting pipes 32 are equal, and the number of second opening slots 311 and supporting pipes 32 are both set to an even number.

[0064] Specifically, the number of second opening slots 311 and the number of bearing tubes 32 are equal and both are set to an even number. This design not only ensures the symmetry of the structure, but also facilitates the orderly collection and storage of snow samples in actual operation. The even number setting allows the switching turntable 31 to maintain balance when rotating, reducing vibration and noise caused by eccentricity, thereby improving the stability and durability of the overall equipment. At the same time, this design also makes it easier for users to take multiple samples as needed, improving work efficiency.

[0065] In one embodiment of the present invention, such as Figure 6 As shown, the carrier tube 32 includes a glass tube body 321, an upper heat-conducting seat 322, and a lower sealing heat-conducting seat 323. The glass tube body 321 is bonded and fixed to the inner wall of the switching turntable 31. The upper heat-conducting seat 322 and the lower sealing heat-conducting seat 323 are respectively snapped and fixed to the top and bottom of the glass tube body 321. A through groove is opened on the surface of the upper heat-conducting seat 322. Two sets of constant temperature heating plates 33 are slidably connected to the top of the upper heat-conducting seat 322 and the bottom of the lower sealing heat-conducting seat 323, respectively.

[0066] It should be noted that a liquid level sensor (not shown in the figure) is provided on the lower sealing heat conduction seat 323 described in this embodiment. The liquid level sensor is electrically connected to the controller 4, and the liquid level data detected by the liquid level sensor is directly displayed on the display screen of the controller 4.

[0067] Specifically, the carrier tube 32 has a very precise and clearly defined structure. It consists of several key parts to ensure the stability and safety of snow samples during collection and storage. First, the glass tube 321, as the core of the carrier tube 32, is fixed to the inner wall of the switching turntable 31 by bonding. This design not only ensures the stability of the glass tube 321 but also prevents damage to the glass tube 321 when the switching turntable 31 rotates. The top and bottom of the glass tube 321 are respectively fixed with an upper heat-conducting seat 322 and a lower sealing heat-conducting seat 323 by snap-fit. These two heat-conducting seats seal the glass tube 321 and, through their thermal conductivity, enable the constant temperature heating plate 33 to more effectively control the temperature inside the glass tube 321. This is crucial for maintaining the temperature of the snow samples. The original state of the sample is crucial, especially when long-term storage or transportation is required. It is particularly worth mentioning that the surface of the upper heat-conducting seat 322 has a through groove. This design allows the snow sample to fall into the glass tube 321 through the through groove. Finally, the two sets of constant temperature heating plates 33 are slidably connected to the top of the upper heat-conducting seat 322 and the bottom of the lower sealing heat-conducting seat 323, respectively. This sliding connection design not only facilitates the installation and removal of the constant temperature heating plates 33, but also allows the position of the heating plates to be adjusted according to actual needs to better adapt to different sizes of carrier tubes 32 or different heating requirements. The precision design of the carrier tube 32 not only ensures the stability and safety of the snow sample during collection and storage, but also achieves precise temperature control of the snow sample through its unique heat-conducting structure, resulting in good performance.

[0068] In one embodiment of the present invention, such as Figure 5 As shown, the surface of the glass tube 321 is provided with scale lines, the surface of the switching turntable 31 is provided with an observation port 313 corresponding to the position of the glass tube 321, and the surface of the lower shell 12 is fixedly engaged with an observation window 15 corresponding to the position of the switching turntable 31.

[0069] Specifically, the scale line design on the surface of the glass tube 321 is a very practical function, providing users with an intuitive visual reference, allowing them to easily read and record the position and height of the snow sample inside the glass tube 321. This design is particularly important when precise control of the snow sample volume or multiple sampling is required. An observation port 313 is provided on the surface of the switching turntable 31 corresponding to the position of the glass tube 321. This observation port 313 allows users to directly observe the snow sample inside the glass tube 321 without opening the switching turntable 31. This design not only improves the convenience of operation but also avoids the risk of temperature fluctuations or contamination that may be caused by frequent opening of the equipment. In addition, an observation window 15 is also snapped and fixed on the surface of the lower shell 12 corresponding to the position of the switching turntable 31. The observation window 15 further enhances the visualization performance of the equipment, allowing users to observe the situation inside the switching turntable 31 and the glass tube 321 from a wider perspective. This is of great significance for monitoring the operating status of the equipment and timely discovering and solving problems. The scale lines on the surface of the glass tube 321, the observation port 313 on the surface of the switching turntable 31, and the observation window 15 on the surface of the lower shell 12 together constitute a complete visualization system, which enables users to observe and record the snow sample more conveniently and accurately, thereby improving the practicality and reliability of the equipment.

[0070] In one embodiment of the present invention, such as Figure 5 As shown, the constant temperature heating plate 33 is C-shaped, and the notch of the constant temperature heating plate 33 corresponds to the position of the first opening groove 14.

[0071] Specifically, the constant temperature heating plate 33 adopts a unique C-shaped design, with its notch cleverly corresponding to the position of the first opening slot 14. This design not only ensures that the constant temperature heating plate 33 can avoid the first opening slot 14 during the heating process, thus avoiding interference with the snow collection operation, but also ensures the uniform distribution of heat, so that the snow sample in the glass tube 321 can be effectively heated and melted. In addition, the C-shaped design also makes the constant temperature heating plate 33 more convenient to install and disassemble, improving the maintainability and flexibility of the equipment.

[0072] In one embodiment of the present invention, such as Figures 6-7As shown, the drive base 34 includes a base body 341, a drive shaft 342, a worm gear 343, a drive gear 344, a worm 345, a driven gear 346, a driving gear 347, a side-mounted gear 348, and a one-way transmission 349. The base body 341 is fixedly connected to the top of the lower shell 12 and located inside the upper shell 11. The drive shaft 342 is rotatably connected to the inner wall of the base body 341. One end of the drive shaft 342 is fixedly connected to the worm gear 343, and the other end of the drive shaft 342 penetrates into the interior of the lower shell 12 and is fixedly connected to the drive gear 344. The drive gear 344 is located on the surface of one end of the central shaft of the switching turntable 31. The driven gear 312 is connected to one side and meshes with each other. The worm 345 is rotatably connected to the inner wall of the base 341 and meshes with the worm wheel 343. The driven gear 346 is fixedly connected to one end surface of the worm 345. The driving gear 347 is rotatably connected to the inner wall of the base 341 and meshes with the driven gear 346. The side gear 348 is rotatably connected to the inner wall of the base 341 and is connected to the driving gear 347 by a one-way transmission 349. One end of the side gear 348 extends out of the outside of the base 341 and is located on one side of the tooth plate 24. The side gear 348 meshes with the teeth on the surface of the tooth plate 24.

[0073] It should be noted that the one-way drive 349 described in this embodiment only drives the drive gear 347 to rotate when the toothed plate 24 rises. The one-way drive 349 is a ratchet-type one-way drive.

[0074] Specifically, the structure and connection relationship of the drive seat 34 are further explained. The drive seat 34 effectively realizes power transmission and has good performance. When in use, when the toothed plate 24 rises, the teeth on its surface contact and mesh with the side gear 348, and synchronously drive the side gear 348 to rotate. The rotation of the side gear 348 synchronously drives the drive gear 347 to rotate through the one-way transmission 349. The rotation of the drive gear 347 synchronously drives the driven gear 346 and the worm 345 to rotate. The rotation of the worm 345 synchronously drives the worm wheel 343, the transmission shaft 342 and the drive gear 344 to rotate. The rotation of the drive gear 344 synchronously drives the driven gear 312 to rotate. The rotation of the driven gear 312 synchronously drives the switching turntable 31 to rotate. The rotation of the switching turntable 31 realizes the switching of the position of the second opening slot 311 and the bearing tube 32.

[0075] A method for using a polar environment snow cover moisture content detection device, applied to the above-mentioned polar environment snow cover moisture content detection device, includes the following steps:

[0076] S1: Install the wall-mounted detection device 10 at a preset position on the surface of the external detection vehicle body, and then connect it to the vehicle power supply;

[0077] S2: After the connection is completed, the device is brought to the snow layer detection point by the external detection vehicle. The operator sends the detection command to the controller 4 through the external remote control handle in the cab. After receiving the command, the controller 4 controls the constant temperature heating plate 33 and the screw lifting mechanism 25 to run in sequence according to the command.

[0078] S3: After the constant temperature heating plate 33 starts running, it heats up and ensures that the temperature is always at the preset temperature. The screw lifting mechanism 25 first drives the slide 21 to descend. The descent of the slide 21 simultaneously drives the snow collection tube 22 and the toothed plate 24 to descend. During the descent, the snow collection tube 22 passes through the first opening slot 14 and the second opening slot 311 and inserts into the snow layer to sample the snow. Then the screw lifting mechanism 25 continues to run, simultaneously driving the snow collection tube 22 and the toothed plate 24 to rise. When the bottom of the snow collection tube 22 moves to the top side of the first opening slot 14, the toothed plate 24 triggers the drive seat 3. 4. During operation, the drive seat 34 drives the switching turntable 31 to rotate at a set angle, thereby switching the positions of the second opening slot 311 and the carrying tube 32. As the snow tube 22 continues to rise, the snow sample inside the snow tube 22 will fall into the carrying tube 32 for collection under the obstruction of the snow baffle 23. As the sampling operation is repeated in the next step, the position of the carrying tube 32 is switched, and it enters the lower shell 12 through the first opening slot 14 and comes into contact with the constant temperature heating plate 33. The snow sample inside the carrying tube 32 is melted by the principle of heat conduction. After the snow sample melts, the amount of water inside the carrying tube 32 can be directly observed through the observation window 15.

[0079] S4: Repeat the above operation to perform multiple snow sample collection operations until all carrier tubes 32 are used up.

[0080] In summary, the polar environment snow layer moisture content detection device and method of this invention have achieved convenient transportation and carrying due to their compact size, while reducing production costs. Their innovative wall-mounted design allows the device to be quickly and easily installed or removed from the external detection vehicle, which not only significantly improves the installation and removal efficiency, but also greatly enhances the flexibility and efficiency of the detection vehicle, bringing users a better user experience.
