[0007] In addition, the polar environment snow layer moisture content detection device proposed in the application may also have the following additional technical features: Specifically, the bottom of the snow collecting cylinder is an open structure, and a strip groove is provided on the surface of the snow collecting cylinder corresponding to the position of the snow blocking plate. One end of the strip groove extends to the bottom of the snow collecting cylinder, and one end of the snow blocking plate passes through the interior of the snow collecting cylinder through the strip groove. The end of the snow blocking plate passing through the interior of the snow collecting cylinder is disc-shaped and matched with the internal size of the snow collecting cylinder.

[0008] Specifically, the outer diameter of the snow collecting barrel is smaller than the inner diameter of the second opening groove and the supporting tube, the outer diameter of the second opening groove and the supporting tube is smaller than the inner diameter of the first opening groove, and the snow collecting barrel, the first opening groove, the second opening groove and the supporting tube are on the same axial line.

[0009] Specifically, the number of the second opening slots is equal to the number of the supporting tubes, and the number of the second opening slots and the number of the supporting tubes are both set to be an even number.

[0010] Specifically, the supporting tube includes a glass tube body, an upper thermal conductive seat and a lower sealed thermal conductive seat. The glass tube body is bonded and fixed to the inner wall of the switching turntable. The upper thermal conductive seat and the lower sealed thermal conductive seat are respectively clamped and fixed to the top and bottom of the glass tube body. A through groove is provided on the surface of the upper thermal conductive seat. The two groups of constant temperature heating plates are respectively slidably connected to the top of the upper thermal conductive seat and the bottom of the lower sealed thermal conductive seat.

[0011] Specifically, the surface of the glass tube body is provided with scale lines, the surface of the switching dial is provided with an observation port at a position corresponding to the position of the glass tube body, and the surface of the lower shell is fixed with an observation window at a position corresponding to the position of the switching dial.

[0014] A method for using a device for detecting the moisture content of snow in a polar environment is applied to the device for detecting the moisture content of snow in a polar environment described above, and comprises the following steps: 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 power supply; S2: After the connection is completed, the device is brought to the snow layer detection point through the external detection vehicle body. The operator sends a detection command to the controller through the external remote control handle in the cab. After receiving the command, the controller controls the operation of the constant temperature heating plate and the screw lifting mechanism in turn according to the command; S3: After the constant temperature heating plate is operated, it generates heat and ensures that the temperature is always at the preset temperature. The operation of the screw lifting mechanism first drives the slide seat to descend, and the descent of the slide seat synchronously drives the snow collecting barrel and the tooth plate to descend. During the descent of the snow collecting barrel, it passes through the first opening slot and the second opening slot and then inserts into the snow layer to sample the snow layer. Then the screw lifting mechanism continues to operate, and the screw lifting mechanism continues to operate and synchronously drives the snow collecting barrel and the tooth plate to rise. When the bottom of the snow collecting barrel moves to the side of the top of the first opening slot, the tooth plate triggers the operation of the driving seat, and the operation of the driving seat drives the switching turntable to rotate the set angle to achieve the position switching of the second opening slot and the supporting tube. As the snow collecting barrel continues to rise, the snow sample inside the snow collecting barrel will fall into the inside of the supporting tube under the obstruction of the snow blocking plate for collection. As the sampling operation is repeated in the next step, the position of the supporting tube is switched, and it enters the lower shell from the first opening slot and contacts with the constant temperature heating plate. The snow sample inside the supporting tube is melted by the heat conduction principle. After the snow sample melts, the amount of water inside the supporting tube can be directly observed through the observation window. S4: Repeat the above operation to implement multiple snow sample collection operations until all the supporting tubes are used up.

[0015] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The device is compact and easy to transport and carry, while reducing production costs.

The snow collecting cylinder 22 is fixed to the inner wall of one end of the slide seat 21 by a threaded connection, and is specially used for accurately sampling from the snow layer. The snow blocking plate 23 is firmly installed on the surface of the upper shell 11, and one end of it cleverly penetrates into the interior of the snow collecting cylinder 22. The unique design lies in that when the snow collecting barrel 22 rises, the snow blocking plate 23 can effectively block the columnar snow sample inside the snow collecting barrel 22, so that it naturally falls into the preset carrying tube 32 under the action of gravity, thereby easily realizing the collection of snow samples. In addition, the tooth plate 24 is fixedly connected to the other end surface of the slide seat 21. This design is cleverly connected with the driving seat 34 in the snow melting carrying peeling assembly 3 to achieve 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, but also improves the control efficiency. The device is innovatively equipped with a snowmelt bearing peeling component 3, which is composed of three core components: a switching turntable 31, a constant temperature heating plate 33 and a driving seat 34. The switching turntable 31 is carefully designed with a second opening groove 311 and a bearing tube 32. The two structures are alternately distributed on the turntable. By rotating the switching turntable 31, the second opening groove 311 and the bearing tube 32 can be flexibly switched back and forth. This design cleverly realizes the multiple collection and storage functions of snow samples. Compared with the traditional method, this switching design significantly reduces the number of unnecessary The transportation time is reduced, thereby greatly improving the detection efficiency. The constant temperature heating plate 33 is another highlight of the component. It is compact in design and occupies very little space. Compared with the prior art, the constant temperature heating plate 33 in the device is not only more advantageous in production cost, but also performs well in use effect. It can stably provide the required temperature environment to ensure the consistency and accuracy of the snow sample during the melting process. The device is provided with a controller 4, which is connected to an external remote control handle through a data interface, so that the operator can perform sampling operations in the car without getting off the car to operate, and is protected from wind and cold, and has a good use effect. ;

[0025] In one embodiment of the present invention, Figure 3 As shown, the bottom of the snow collecting cylinder 22 is an open structure, and a strip groove 221 is provided on the surface of the snow collecting cylinder 22 corresponding to the position of the snow blocking plate 23. One end of the strip groove 221 extends to the bottom of the snow collecting cylinder 22, and one end of the snow blocking plate 23 passes through the interior of the snow collecting cylinder 22 through the strip groove 221. The end of the snow blocking plate 23 passing through the interior of the snow collecting cylinder 22 is disc-shaped and adapted to the internal size of the snow collecting cylinder 22.

[0026] It should be noted that the snow blocking plate 23 described in this embodiment is detachably arranged on the surface of the upper shell 11 to achieve free position adjustment.

[0027] Specifically, this section mainly describes the design details of the snow collecting barrel 22 and the snow blocking plate 23. The bottom of the snow collecting barrel 22 is designed as an open structure, which means that its bottom is open and can easily collect or release snow samples. On the surface of the snow collecting barrel 22, there is a strip groove 221 corresponding to the position of the snow blocking plate 23. One end of the strip groove 221 extends to the bottom of the snow collecting barrel 22, which provides a channel for the snow blocking plate 23 to pass through the strip groove 221 from the outside to enter the interior of the snow collecting barrel 22. The snow blocking plate 23 One end of the snow blocking plate 23 passes through the wall of the snow collecting barrel 22 through the strip groove 221 and enters the interior of the snow collecting barrel 22. The end of the snow blocking plate 23 entering the interior of the snow collecting barrel 22 is designed to be disc-shaped. This shape enables it to match the internal size of the snow collecting barrel 22, thereby effectively blocking the snow sample. The snow blocking plate 23 is used to prevent the movement of snow, while the snow collecting barrel 22 is used to collect and store snow. By adjusting the position of the snow blocking plate 23 inside the snow collecting barrel 22, the snow sample can be controlled to meet different operating requirements, and the use effect is good.

[0028] In one embodiment of the present invention, Figure 1-Figure 5 As shown, the outer diameter of the snow collecting barrel 22 is smaller than the inner diameter of the second opening groove 311 and the supporting tube 32, and the outer diameters of the second opening groove 311 and the supporting tube 32 are smaller than the inner diameter of the first opening groove 14. The snow collecting barrel 22, the first opening groove 14, the second opening groove 311 and the supporting tube 32 are on the same axial line.

[0029] Specifically, the outer diameter of the snow collecting barrel 22 is carefully designed to be smaller than the inner diameters of the second opening groove 311 and the supporting tube 32, ensuring that the snow collecting barrel 22 can smoothly pass through the second opening groove 311 and the snow sample can smoothly fall into the supporting tube 32. The outer diameters of the second opening groove 311 and the supporting tube 32 are also set to be smaller than the inner diameter of the first opening groove 14, which means that they can easily be located in the first opening groove 14 without interference. It is worth noting that the snow collecting barrel 22, the first opening groove 14, the second opening groove 311 and the supporting tube 32 all cleverly share the same axis. This precise centering design not only ensures the smooth cooperation between the various components, but also improves the stability of the overall structure and the accuracy of operation.

[0030] In one embodiment of the present invention, Figure 5 As shown, the number of the second opening slots 311 and the number of the supporting tubes 32 are equal, and the number of the second opening slots 311 and the number of the supporting tubes 32 are both set to be an even number.

[0031] Specifically, the number of second opening slots 311 and supporting tubes 32 is equal, and both are set to an even number. Such a 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 enables the switching turntable 31 to maintain balance during rotation, reducing the vibration and noise caused by eccentricity, thereby improving the stability and durability of the overall equipment. At the same time, this design also facilitates users to perform multiple sampling as needed, thereby improving work efficiency.

[0032] In one embodiment of the present invention, Figure 6 As shown, the supporting tube 32 includes a glass tube body 321, an upper heat-conducting seat 322 and a lower sealed heat-conducting seat 323. The glass tube body 321 is bonded and fixed to the inner wall of the switching turntable 31, and the upper heat-conducting seat 322 and the lower sealed heat-conducting seat 323 are respectively clamped and fixed to the top and bottom of the glass tube body 321. A through groove is provided on the surface of the upper heat-conducting seat 322, and 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 sealed heat-conducting seat 323 respectively.

[0033] It should be noted that a liquid level sensor (not shown in the figure) is provided on the lower blocking heat conductive 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 .

[0034] Specifically, the structure of the supporting tube 32 is very precise and the function is clear. It is composed of several key parts to ensure the stability and safety of the snow sample during the collection and storage process. First, the glass tube body 321, as the core of the supporting 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 body 321, but also prevents the switching turntable 31 from causing damage to the glass tube body 321 when rotating. The top and bottom of the glass tube body 321 are respectively fixed with the upper heat-conducting seat 322 and the lower blocking heat-conducting seat 323 by snap-fitting. These two heat-conducting seats play the role of sealing the glass tube body 321. Through their thermal conductivity, the constant temperature heating plate 33 can more effectively control the temperature inside the glass tube body 321, which is very important for maintaining the snow sample. The original state of the sample is crucial, especially when it needs to be stored or transported for a long time. It is particularly worth mentioning that a through groove is opened on the surface of the upper heat-conducting seat 322. This design allows the snow sample to fall into the glass tube body 321 through the through groove. Finally, the two sets of constant temperature heating plates 33 are slidingly connected to the top of the upper heat-conducting seat 322 and the bottom of the lower blocking heat-conducting seat 323 respectively. This sliding connection design not only facilitates the installation and disassembly of the constant temperature heating plate 33, but also allows the position of the heating plate to be adjusted according to actual needs to better adapt to different sizes of supporting tubes 32 or different heating requirements. The precise design of the supporting tube 32 not only ensures the stability and safety of the snow sample during collection and storage, but also through its unique heat-conducting structure, it realizes precise control of the temperature of the snow sample, and the use effect is good.

[0035] In one embodiment of the present invention, Figure 5 As shown, the surface of the glass tube body 321 is provided with scale lines, the surface of the switching dial 31 is provided with an observation port 313 at a position corresponding to the glass tube body 321 , and the surface of the lower shell 12 is fixed with an observation window 15 at a position corresponding to the switching dial 31 .

[0036] Specifically, the scale line design on the surface of the glass tube body 321 is a very practical function. It provides an intuitive visual reference for the user, allowing the user to easily read and record the position and height of the snow sample in the glass tube body 321. This design is particularly important when the amount of snow sample needs to be precisely controlled or multiple samplings are required. An observation port 313 is set on the surface of the switching dial 31 corresponding to the position of the glass tube body 321. This observation port 313 allows the user to directly observe the snow sample situation in the glass tube body 321 through it without opening the switching dial 31. This design not only improves the convenience of operation, but also avoids the temperature fluctuations or contamination risks that may be caused by frequent opening of the equipment. In addition, an observation window 15 is also clamped and fixed on the surface of the lower shell 12 corresponding to the position of the switching dial 31. The observation window 15 further enhances the visualization performance of the equipment, allowing the user to observe the switching dial 31 and the glass tube body 321 from a wider viewing angle. This is of great significance for monitoring the operating status of the equipment, and promptly discovering and solving problems. The scale lines on the surface of the glass tube body 321, the observation port 313 on the surface of the switching dial 31, and the observation window 15 on the surface of the lower shell 12 together constitute a complete visualization system, allowing users to observe and record the conditions of the snow sample more conveniently and accurately, thereby improving the practicability and reliability of the equipment.

[0037] In one embodiment of the present invention, 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 .

[0038] Specifically, the constant temperature heating plate 33 adopts a unique C-shaped design, and its notched part cleverly corresponds to the position of the first opening groove 14. This design not only ensures that the constant temperature heating plate 33 can avoid the first opening groove 14 during the heating process, avoiding interference with the snow removal operation, but also ensures the uniform distribution of heat, so that the snow sample in the glass tube body 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, thereby improving the maintainability and flexibility of the equipment.

The seat body 341 is fixedly connected to the top of the lower shell 12 and is located inside the upper shell 11. The transmission shaft 342 is rotatably connected to the inner wall of the seat body 341. One end of the transmission shaft 342 is fixedly connected to the worm wheel 343. The other end of the transmission shaft 342 penetrates into the lower shell 12 and is fixedly connected to the driving gear 344. The driving gear 344 is located on the surface of one end of the central axis of the switching turntable 31. The worm 345 is rotatably connected to the inner wall of the seat body 341 and meshes with the worm wheel 343. The driven gear 346 is fixedly connected to the surface of one end of the worm 345. The driving gear 347 is rotatably connected to the inner wall of the seat body 341 and meshes with the driven gear 346. The side gear 348 is rotatably connected to the inner wall of the seat body 341 and meshes with the driven gear 346. A one-way transmission device 349 is connected between the side gear 348 and the driving gear 347. One end of the side gear 348 passes through the outside of the seat body 341 and is located on one side of the tooth plate 24. The side gear 348 is meshed with the teeth on the surface of the tooth plate 24.

[0040] It should be noted that the one-way transmission 349 described in this embodiment will drive the driving gear 347 to rotate only when the tooth plate 24 rises, and the one-way transmission 349 is a ratchet one-way transmission.

[0041] 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 use effect. When in use, when the tooth 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 driving gear 347 to rotate through the one-way transmission 349. The rotation of the driving 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 driving gear 344 to rotate. The rotation of the driving gear 344 synchronously drives the driven gear 312 to rotate. The rotation of the driven gear 312 synchronously drives the switching dial 31 to rotate. The rotation of the switching dial 31 realizes the switching of the second opening slot 311 and the position of the supporting tube 32.

[0042] A method for using a device for detecting the moisture content of snow in a polar environment is applied to the above-mentioned device for detecting the moisture content of snow in a polar environment, and comprises the following steps: 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; S2: After the connection is completed, the device is brought to the snow layer detection point through the external detection vehicle body, and the operator sends a detection command to the controller 4 through the external remote control handle in the cab. After receiving the command, the controller 4 controls the operation of the constant temperature heating plate 33 and the screw lifting mechanism 25 in turn according to the command; S3: The constant temperature heating plate 33 generates heat after operation and ensures that the temperature is always at the preset temperature. The screw lifting mechanism 25 first drives the slide 21 to descend, and the descent of the slide 21 synchronously drives the snow collecting barrel 22 and the tooth plate 24 to descend. During the descent of the snow collecting barrel 22, it passes through the first opening groove 14 and the second opening groove 311 and is inserted into the snow layer to sample the snow layer. Then the screw lifting mechanism 25 continues to operate, and the screw lifting mechanism 25 continues to operate and synchronously drives the snow collecting barrel 22 and the tooth plate 24 to rise. When the bottom of the snow collecting barrel 22 moves to the top side of the first opening groove 14, the tooth plate 24 triggers the drive seat 3 4, the driving seat 34 drives the switching turntable 31 to rotate the set angle to realize the position switching of the second opening slot 311 and the supporting tube 32. As the snow collecting cylinder 22 continues to rise, the snow sample inside the snow collecting cylinder 22 will all fall into the inside of the supporting tube 32 under the blockage of the snow blocking plate 23 for collection. As the sampling operation is repeated in the next step, the position of the supporting tube 32 is switched, and it enters the inside of the lower shell 12 from the first opening slot 14 and contacts the constant temperature heating plate 33. The snow sample inside the supporting tube 32 is melted by the principle of heat conduction. After the snow sample melts, the water volume inside the supporting tube 32 can be directly observed through the observation window 15; S4: Repeat the above operation to implement multiple snow sample collection operations until all the supporting tubes 32 are used up.

The device, with its compact size, achieves convenient transportation and carrying while reducing production costs. Its innovative wall-mounted design enables the device to be quickly and easily installed or disassembled on an external detection vehicle body, which not only significantly improves the efficiency of assembly and disassembly, but also greatly improves the flexibility and efficiency of the detection vehicle body, bringing users a more excellent user experience.
