Description
Technical Field

[0030] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0031] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.
[0032] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "rear," and the like. Such spatially relative terms are intended to encompass different orientations of the device during use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip, a change in posture, or a change in motion, the directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature would subsequently be oriented "above" or "above" the other element or feature. Thus, the example term "below" can encompass both above and below orientations. The device may be alternatively oriented rotated 90 degrees or in other orientations and the spatially relative descriptors used herein should be interpreted accordingly.
[0033] like Figures 1 to 5 As shown, in some exemplary embodiments of the present application, a snow thickness detection and testing device is provided, which mainly includes a displacement assembly 10, a measuring rod group 20 and a baffle assembly 30, wherein the displacement assembly 10 includes an integrated mounting portion 11 and a displacement structure 12; the measuring rod group 20 includes a rod body 21, a reference structure 22 and a sliding structure 23, the reference structure 22 and the sliding structure 23 are fixedly connected, the rod body 21 is detachably connected to the mounting portion 11, the rod body 21 is provided with a plurality of reference lines 212 along its length direction, the sliding structure 23 can slide relative to the rod body 21 along its length direction, and the length direction of the rod body 21 is perpendicular to the moving direction of the displacement structure 12; the baffle assembly 30 includes a first baffle 31 and a second baffle 32 set at an angle, and the first baffle 31 or the second baffle 32 is detachably connected to the sliding structure 23.
[0034] The measuring rod group 20 can measure the thickness of snow through the reference line 212 on its rod body 21, and calculate the height position of the snow surface that needs to be trimmed based on the measurement results. Then, the thickness of the snow that needs to be removed is determined, and the position of the sliding structure 23 is adjusted to adjust the position of the baffle assembly 30. The reference structure 22 can cooperate with the reference line 212 to achieve high-precision adjustment of the position of the baffle assembly 30, thereby ensuring that the thickness of the snow after processing meets the requirements of the experiment. After the adjustment is completed, the displacement assembly 10 drives the rod body 21 and the baffle assembly 30 to move, pushing out the excess snow, and achieving height trimming of the snow surface. The application of the above solution can not only help users effectively control the snow surface and its thickness in the experiment, but also meet the test requirements of snow-related experiments.
[0035] It is understandable that the above-mentioned arrangement makes the connection between the various components simple and reliable, easy to assemble and disassemble, and greatly improves the portability and practicality of the device. Specifically, the rod body 21 is detachably connected to the mounting portion 11. A plug-in block 215 is provided at one end of the rod body 21, and a mounting portion 11 is provided on the side of the displacement structure 12 facing the rod body 21. The mounting portion 11 can specifically be a groove that can be snapped into the shape of the plug-in block 215. When the plug-in block 215 is inserted into the mounting portion 11, the rod body 21 forms a limit for the circumferential degree of freedom. Under the action of gravity, the L-shaped step formed by the plug-in block 215 and the main part of the rod body 21 forms a limit with the notch position of the mounting portion 11, and will not fall off at this time, ensuring the vertical position accuracy of the rod body 21.
[0036] The sliding structure 23 can slide relative to the rod body 21 along its length to ensure that its adjustment direction is consistent with the extension direction of the rod body 21. Optionally, the sliding structure 23 can slide relative to the rod body 21 by providing a slide rail and a slider, a pulley and a slide rail, a lead screw and a threaded pair, etc., which are not particularly limited here.
[0037] The first baffle 31 and the second baffle 32 arranged at an angle can realize the combination of baffles of different lengths and angles with the sliding structure 23, so as to meet the requirements of removing snow layers of different thicknesses.
[0038] Furthermore, if Figures 1 to 5 As shown, in some exemplary embodiments of the present application, the first baffle 31 is fixedly connected to the second baffle 32 and is arranged at a right angle, and the width of the first baffle 31 extending along its surface from the intersection line is not equal to the width of the second baffle 32 extending along its surface from the intersection line.
[0039] The right-angle connection between the first baffle 31 and the second baffle 32 enhances the overall stability of the baffle assembly and ensures that snow is effectively guided and removed during the pushing process, preventing snow accumulation or leakage. It should be understood that the pushing direction is along the plane of the first baffle 31 or the second baffle 32, that is, perpendicular to the upright baffle. In this case, the plane of the snow removal baffle directly aligns with the snow, achieving maximum pushing force and more efficient snow removal.
[0040] The width of the first baffle 31 is different from that of the second baffle 32, which can adapt to different snow thickness adjustment requirements. For example, when the snow thickness needs to be quickly processed, a wider baffle can be used as the contact surface of the snow. At this time, more snow can be directly pushed away to quickly meet the requirements of the snow experiment; when the snow surface needs to have higher precision, a narrower baffle can be selected as the contact surface of the snow. At this time, the upper surface of the snow will have more contact with the wider baffle, and the degree of friction is relatively large. At this time, the upper surface of the snow can be better smoothed, so that the position accuracy and surface accuracy of the upper surface are higher.
[0041] In some exemplary embodiments of the present application (not shown in the figures), the width of the first baffle 31 extending from the intersection line along its surface is between 15 cm and 20 cm, and the width of the second baffle 32 extending from the intersection line along its surface is between 8 cm and 12 cm. The width setting of the first baffle 31 is suitable for clearing thick snow. In this case, the distance passed by the second baffle 32 is between 8 cm and 12 cm, and the contact area with the snow surface is relatively small, that is, the frictional resistance is relatively small, which can quickly clear thick snow. In contrast, the width setting of the second baffle 32 is suitable for clearing snow surfaces with higher precision requirements. The second baffle 32 removes thinner snow with less resistance. At the same time, the distance passed by the first baffle 31 is between 15 cm and 20 cm, which can effectively adjust the surface precision of the upper surface of the snow, thereby controlling the snow thickness more accurately.
[0042] It can be understood that the width range of the first baffle 31 and the second baffle 32 is between 8 cm and 20 cm, and can be effectively controlled within 0 cm to 20 cm according to the actual baseline 212 and the sliding structure 23. The general snow thickness is relatively small, and the thickness that needs to be adjusted will not exceed 20 cm. Therefore, the above-mentioned baffle width range is sufficient to meet the requirements of snow-related experiments.
[0043] like Figures 1 to 3 As shown, in some exemplary embodiments of the present application, the snow thickness detection and testing device also includes a plurality of quick-release mounting structures 40, and the baffle assembly 30 is correspondingly provided with a plurality of pairs of first baffles 31 and second baffles 32, and adjacent first baffles 31 are detachably connected through a quick-release mounting structure 40, and adjacent second baffles 32 are detachably connected through a quick-release mounting structure 40.
[0044] The arrangement of multiple pairs of first and second baffles 31, 32 and multiple quick-release mounting structures 40 can accommodate different spans. Common snow test sites can range from 80 cm to 200 cm, but a single first baffle 31 is relatively inadequate. For example, a baffle used in an 80 cm site is not long enough for a 200 cm site, while a baffle used in a 200 cm site is too long and inconvenient to operate in an 80 cm site. However, the detachable first and second baffles 31, 32 can effectively accommodate sites of varying lengths.
[0045] In one embodiment, the length of the first baffle 31 and the second baffle 32 is 25 cm. When an 80 cm space is required, a 100 cm long baffle can be built through four baffle assemblies 30 and three quick-release mounting structures 40, which can meet the needs of an 80 cm space without being too long and has good adaptability.
[0046] To facilitate the transportation of the baffle assembly 30, the first baffle 31 and the second baffle 32 can be set as an integrally formed structure, made of lightweight steel or alloy materials, such as aluminum alloy, etc. The first baffle 31 and the second baffle 32 are fixed together by welding, or the first baffle 31 and the second baffle 32 are formed into an L-shape by stamping.
[0047] like Figures 1 to 3 As shown, in some exemplary embodiments of the present application, a mounting hole 33 is provided on the side of the first baffle 31 and / or the second baffle 32 away from the intersection line, and the quick-release mounting structure 40 includes a fixedly connected connecting plate 41 and a first connecting column 42, the first connecting column 42 passes through the mounting hole 33 of the adjacent first baffle 31 and / or the second baffle 32, and the first fastener 43 is locked and connected to one end of the first connecting column 42 away from the connecting plate 41.
[0048] The mounting hole 33 is provided for assembling the first connecting column 42 , and the first fastener 43 forms a radial limit for the first baffle 31 and / or the second baffle 32 on the first connecting column 42 , that is, the relative position accuracy with respect to the snow surface.
[0049] Specifically, a thread is provided on the cylindrical surface of the first connecting column 42, and the first fastener 43 is specifically a nut. By tightening the nut, the first baffle 31 and / or the second baffle 32 are tightly combined with the connecting plate 41. The self-locking characteristics of the thread are utilized to prevent the two from being damaged after being combined.
[0050] It is understood that the provision of multiple mounting holes 33 and multiple first connecting posts 42 along the length of the first baffles 31 and / or second baffles 32 limits the circumferential freedom of movement after adjacent first baffles 31 and / or second baffles 32 are joined. Furthermore, the abutment between adjacent first baffles 31 and / or second baffles 32 further limits the circumferential freedom of movement and ensures that, after joining, there is no difference in the precision of the mating position with the snow surface.
[0051] Optionally, along the length direction of the first baffle 31 and / or the second baffle 32, the first connecting column 42 cooperates with the mounting holes 33 on the adjacent first baffle 31 and / or the second baffle 32, respectively, so that the connection position along the length direction of the first baffle 31 and / or the second baffle 32 can be increased, thereby increasing the connection strength of the connection position between the two.
[0052] like Figures 1 to 3 As shown, in some exemplary embodiments of the present application, the first baffle 31 and / or the second baffle 32 are provided with mounting grooves 34 corresponding to the mounting holes 33, and the mounting grooves 34 are located on the side away from the intersection surface of the first baffle 31 and the second baffle 32, and / or the mounting grooves 34 are located on the side away from the intersection surface of the second baffle 32 and the first baffle 31, and the depth of the mounting grooves 34 is less than the thickness of the connecting plate 41.
[0053] The installation groove 34 prevents the connection plate 41 from contacting the snow surface in the direction away from the first baffle 31 or the second baffle 32. That is, when the first baffle 31 and the second baffle 32 are in contact with the snow surface, the connection plate 41 is suspended in the air, thereby ensuring the accuracy of the snow thickness.
[0054] Optionally, a quick-release mounting structure 40 is provided between adjacent first baffles 31 and adjacent second baffles 32 , thereby increasing the bonding between adjacent baffle assemblies 30 and improving their reliability.
[0055] like Figures 4 to 7 As shown, in some exemplary embodiments of the present application, the sliding structure 23 is provided with a second connecting column 231 and a receiving plate 232, the second connecting column 231 passes through the mounting hole 33 of the first baffle 31 and / or the second baffle 32, and the second fastener 233 is locked and connected to the end of the second connecting column 231 away from the receiving plate 232.
[0056] The second connecting column 231 is similarly arranged to the first connecting column and is used for the specific connection of the baffle assemblies 30 at both ends.
[0057] Specifically, multiple second connecting columns 231 pass through multiple mounting holes 33 to form a circumferential limit on the mountain. At the same time, the second fasteners 233 form a radial limit on the first baffle 31 and / or the second baffle 32 on the first connecting column 42 to ensure the relative position accuracy with the snow surface.
[0058] Optionally, a thread is provided on the cylindrical surface of the second connecting column 231, and the second fastener 233 is specifically a nut. By tightening the nut, the first baffle 31 and / or the second baffle 32 are tightly combined with the receiving plate 232, and the self-locking characteristics of the thread are utilized to prevent the two from being damaged after being combined.
[0059] like Figure 8 As shown, in some exemplary embodiments of the present application, the cross section of the rod body 21 is a polyhedron, and reference lines 212 are provided on any two side surfaces of the rod body 21 , and the starting points of the two reference lines 212 are respectively located at opposite ends of the rod body 21 .
[0060] This arrangement allows the rod 21 to perform different measurements from both ends, adapting to different measurement environments. For example, for simple measurements, the rod 21 can be inverted and directly inserted into the test snow field, so that the top end of the rod 21, that is, the end away from the plug block 215, directly contacts the ground. At this time, the corresponding reading of the reference line 212 is collected to obtain the corresponding snow thickness. When measuring and removing snow, the plug block 215 is inserted into the mounting portion 11, and the reading on the corresponding reference line 212 is read to obtain the corresponding snow thickness.
[0061] It should be noted that the initial reading position at the end where the plug-in block 215 is provided retains the actual height after being combined with the displacement component 10, so that there will be no reading deviation or the need to calculate the height of the displacement component 10, reducing the calculation process.
[0062] like Figure 8 As shown, in some exemplary embodiments of the present application, an assembly hole 213 and a handle 214 are provided at one end of the rod body 21 away from the plug-in block 215, and the handle 214 is detachably connected to the assembly hole 213 so that the user can use the handle 214 to push the snow thickness detection and testing device.
[0063] One end of the handle 214 can be specifically configured as a threaded column, and the corresponding handle 214 is provided with an internal thread, and the threaded column is threadedly matched with the internal threaded hole to achieve disassembly, assembly and fixation.
[0064] like Figure 1 、 Figures 4 to 8As shown, in some exemplary embodiments of the present application, the rod body 21 is provided with a sliding groove body 211, and the sliding structure 23 is provided with a sliding block 234 corresponding to the sliding groove body 211, the sliding block 234 is adapted to the shape of the sliding groove body 211, and a locking structure 50 is provided between the sliding structure 23 and the rod body 21.
[0065] The arrangement of the sliding groove 211 can provide the sliding structure 23 with a precise sliding direction, and provide good control over the height position adjustment of the sliding structure 23 .
[0066] The sliding block 234 is adapted to the shape of the sliding groove body 211, which can limit the circumferential freedom of the sliding block 234, thereby avoiding shaking, etc., thereby reducing the impact on the snow surface during the displacement process and reducing the error factors caused by preparation work before the test begins.
[0067] In a specific embodiment, the cross-sectional shape of the sliding block 234 is T-shaped, and the corresponding cross-sectional shape of the sliding groove body 211 is T-shaped. The T-shaped setting restricts the two sides of the sliding block 234, thereby achieving better circumferential freedom restriction and expanding the relative sliding channel, thereby increasing the sliding accuracy.
[0068] like Figures 4 to 7 As shown, in some exemplary embodiments of the present application, the sliding structure 23 includes an extension arm 235 adapted to the side of the rod body 21, and the locking structure 50 includes an elastic member 51, a limiting rod 52 and a gasket 53. The limiting rod 52 passes through the extension arm 235 and abuts against the side of the rod body 21. The elastic member 51 is respectively connected to the extension arm 235 and the end of the limiting rod 52 away from the rod body 21, and the elastic member 51 applies pulling force to the extension arm 235 and the end of the limiting rod 52 away from the rod body 21.
[0069] The extension arm 235 is set to fix the extension arm 235 to one side of the receiving plate 232, and extend backward to the side of the rod body 21 opposite to the receiving plate 232, forming a semi-enclosed structure, which is used to increase the fit between the sliding structure 23 and the rod body 21, ensuring that the sliding structure 23 will not fall off or get stuck due to the load of the receiving plate 232.
[0070] The setting of the locking structure 50 enables the limiting rod 52 to maintain pressure on the side of the rod body 21, so that the limiting rod 52 and the rod body 21 remain relatively stationary, and the limiting rod 52 passes through the extension arm 235 so that the two form a circumferential freedom limit to prevent them from falling off. At this time, the limiting rod 52 plays the role of keeping the sliding structure 23 from falling off.
[0071] It should be noted that the reference structure 22 is connected to the side of the receiving plate 232 away from the extension arm 235, and the lower part of the reference structure 22 remains parallel to the reference line 212, which facilitates the position acquisition of the reference structure 22.
[0072] Furthermore, the lower side of the reference structure 22 is flush with the snow contact surface of the baffle assembly 30 , thereby maintaining the reliable position accuracy of the snow contact surface of the baffle assembly 30 .
[0073] like Figure 9 As shown, in some exemplary embodiments of the present application, the displacement assembly 10 further includes an insert 13, a socket 14 and a roller 15. The roller 15 is connected to the side of the displacement structure 12 away from the mounting portion 11 through a bracket to facilitate pushing. The insert 13 and the socket 14 are respectively arranged on opposite sides of the displacement structure 12, and the insert 13 can be inserted into the socket 14 to form a connection between the two displacement assemblies 10. Such an arrangement can increase the flexibility of the displacement assembly 10.
[0074] It can be understood that since the baffle assembly 30 is located on one side of the rod body 21, when its span is long, the entire snow thickness detection and testing device is easily overturned due to the factor of gravity. By adding multiple displacement assemblies 10 along the setting direction of the baffle assembly 30, the span of the entire snow thickness detection and testing device can be increased, and the center of gravity of the snow thickness detection and testing device can be dispersed, thereby avoiding the occurrence of tipping.
[0075] In addition to adding multiple displacement components 10, a counterweight block can also be added to the rod body 21 close to the ground to lower the center of gravity of the entire snow thickness detection and testing device, thereby maintaining its stability.
