[0028] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure more clear, the embodiments of the present disclosure are further described in detail below in combination with the embodiments and drawings. The schematic implementation methods of the embodiments of the present disclosure and their descriptions are only used to explain the embodiments of the present disclosure and are not intended to limit the embodiments of the present disclosure.

[0029] like Figure 1 As shown, a snowfall intensity monitoring device of the present application includes a support frame 1, a windshield 2, a snow collection bucket 3, a sliding guide 4 and a displacement sensor 5. The device achieves accurate snowfall intensity measurement in strong wind weather through the coordinated operation of various parts.

[0030] The support frame 1 is used to secure and support the entire device, ensuring its stability and reliability in all weather conditions. It is typically made of metal and possesses sufficient rigidity and strength to withstand wind and other external forces. A base 11 or footing is located at the bottom of the support frame 1, securely fastened to the ground or other stable foundation using bolts or other fixings.

[0031] Windshield 2 (see Figure 2 ) is mounted on support frame 1 to shield snowfall measurements from strong external winds. Made of lightweight, high-strength material, the windshield 2, often in a hemispherical or conical shape, effectively reduces wind resistance. The spacious interior of the windshield 2 accommodates the snow collection hopper 3 and other sensors, ensuring that data collected during snowfall collection is not disturbed by external factors.

[0032] The snow collection hopper 3, located within the windshield 2, is primarily used to collect snow samples. Made of a smooth, ice-resistant material, it ensures smooth snowfall collection. The design of the snow collection hopper 3 takes into account the requirements for freezing and icing resistance, as well as ease of cleaning, ensuring long-term, efficient operation. The collection hopper is secured to a sliding rail 4 via connectors and is guided by the rail to allow for vertical movement.

[0033] The sliding rail 4 is mounted on the support frame 1 and connected to the snow collecting hopper 3, guiding the vertical movement of the snow collecting hopper 3. Made of weather-resistant material, the sliding rail 4 ensures smooth movement in all weather conditions. Limiters are installed at both ends of the rail to prevent the collecting hopper from deviating from the track. By adjusting the position of the sliding rail 4, the snow collecting hopper 3 can be adjusted to the optimal sampling height to accommodate varying snowfall conditions and minimize the impact of wind on measurement results.

[0034] A displacement sensor 5 is fixed to one end of the sliding guide rail 4 and is used to detect the vertical displacement of the snow collecting hopper 3. This displacement sensor 5 uses a precision displacement measurement device (such as a photoelectric encoder or linear displacement sensor) to accurately measure the displacement of the snow collecting hopper 3, thereby indirectly reflecting changes in snowfall intensity. After processing and calibration, the sensor output data can be converted into intuitive snowfall intensity information.

[0035] The device's components work together to address the problem of interference between the wind speed sensor and the snowfall intensity sensor, often caused by complex airflow caused by snow drifting in strong winds. The windshield 2 reduces the impact of external wind on snowfall data collected internally, while the sliding guide 4 and displacement sensor 5 accurately monitor changes in snowfall intensity in real time, ensuring data reliability and accuracy. This design not only improves measurement accuracy but also extends the device's lifespan, making it suitable for a variety of snowfall monitoring scenarios.

[0036] In one embodiment, a support frame 1 of a snowfall intensity monitoring device of the present application adopts a multi-layer structural design, including a base 11, an intermediate support rod 12 and a top mounting platform 13. The base 11 is fixed to the ground and serves as a foundation for stabilizing the entire device. The intermediate support rod 12 connects the base 11 and the top mounting platform 13, and is used to support the main weight of the monitoring equipment. The intermediate support rod 12 is provided with an adjustable fixing buckle 14, which can quickly adjust the height and angle according to the needs of the actual site environment, thereby ensuring the stability of the entire device under different terrain conditions. The top mounting platform 13 is used to fix and install various monitoring sensors to ensure their normal operation.

[0037] Specifically, the base 11 of the support frame 1 is designed as a sturdy planar structure, usually made of metal material to ensure good contact with the ground. The intermediate support rod 12 is a columnar structure, and its material selection should have sufficient strength and corrosion resistance to ensure stability in long-term use. The adjustable fixing buckle 14 is installed at different positions of the intermediate support rod 12. The position of the buckle is adjusted by a knob or nut, so that the monitoring device can adapt to different working environments. In addition, the top mounting platform 13 is provided with a plurality of fixing holes to facilitate the installation and maintenance of various sensors. For example, in one embodiment, by adjusting the adjustable fixing buckle 14, the top mounting platform 13 can be kept in a horizontal state, thereby reducing the interference of external wind on the monitoring results.

[0038] In one embodiment, a windshield 2 of a snowfall intensity monitoring device of the present application adopts a streamlined design. The streamlined design can effectively reduce air resistance under high wind speed conditions and reduce the interference of wind on the monitoring device. In order to further enhance the windproof effect, a deflector 21 is provided on the top of the windshield 2. The shape of the deflector 21 is specially designed to deflect strong wind airflow to one side, thereby reducing the wind force directly blowing towards the snowfall collection bucket 3. Such a design not only ensures the accuracy of snowfall collection, but also ensures the reliability of the data. The windshield 2 is made of high-strength weathering steel, which has excellent mechanical properties and corrosion resistance, and can maintain structural stability and intact functionality for a long time under extreme climatic conditions.

[0039] In one embodiment, the windshield 2 is mounted on the outermost layer of the monitoring device, with its lower portion secured to the device's main frame by bolts or welding. Deflectors 21 are secured to the top surface of the windshield 2 at four locations around the device via welding or other secure attachment methods, and are arranged in a staggered pattern to ensure stability and resistance to deformation under various environmental conditions. Specifically, the deflectors 21 can be wedge-shaped or arc-shaped to more effectively disperse wind forces. In this application, a staggered pattern refers to the partial overlap of different deflectors 21, with the overlapping relationship staggered. For example, the deflectors may be arc-shaped, with a first deflector partially overlapping a second deflector, with the first deflector positioned above the second in the overlapping portion. Furthermore, the second deflector partially overlaps a third deflector, with the second deflector positioned below the third in the overlapping portion, and so on. Gaps are provided between the overlapping portions of the deflectors to form air flow channels, which direct wind toward the exterior of the windshield 2, thereby avoiding impact on the snow collection hopper 3.

[0040] In one embodiment, Figure 1As shown, the snow collection hopper 3 of a snowfall intensity monitoring device of the present application utilizes a conical structure. This structural design facilitates the collection and guidance of snowfall, ensuring that snow samples are effectively gathered at the bottom of the hopper. An automatic drain 31 is provided at the bottom, primarily for removing accumulated moisture within the hopper to prevent it from affecting the purity of the snow sample. Furthermore, a number of air holes 32 are provided on the sidewalls. These holes 32 have a diameter smaller than the maximum snowfall particle size, ensuring that snowflakes can enter the collection hopper smoothly without being dragged in by wind, thereby preventing the snow sample from being swept away or dispersed by strong winds during the collection process.

[0041] Furthermore, there are no fewer than four air holes 32 evenly distributed along the sidewalls of the snow collection hopper 3, with a spacing of 10 cm between each pair. This layout effectively disperses the airflow entering the hopper, further reducing the impact of wind speed on the snow sample, ensuring that the collected snow sample is closer to its natural state. To prevent liquid water from draining out of the automatic drain 31 and carrying away part of the snow sample, a filter 33 is installed at the automatic drain 31. The pore size of the filter 33 is smaller than the maximum size of the snow particles, ensuring that only liquid water can pass through, while the solid snow sample is retained in the hopper, thereby improving measurement accuracy.

[0042] For example, the air holes 32 of the snow collection hopper 3 can be drilled into the sidewall using a precision punch during the manufacturing process, ensuring that the diameter and spacing of the air holes 32 meet the design requirements. The filter 33 can be made of corrosion-resistant, high-strength stainless steel and fixed inside the automatic drain 31 during installation, ensuring its firmness and reliability and effective water filtration, thereby achieving accurate snow sample collection.

[0043] In one embodiment, Figure 2 As shown, a snow collection hopper 3 of a snowfall intensity monitoring device according to the present application is further provided with a shielding cover 34 on top. When there is no snow, shielding cover 34 can be closed to prevent rainwater and other impurities from entering the snow collection hopper 3, thereby preventing these external factors from contaminating the snow sample. When there is snow, shielding cover 34 can be opened to ensure that the snow sample can enter the collection hopper smoothly, thereby ensuring accurate and reliable sampling. The opening and closing mechanism of shielding cover 34 can be controlled manually or by an automatic sensor as needed.

[0044] For example, the shielding cover 34 can be installed on the top edge of the snow collecting bucket 3 and fixedly connected to the snow collecting bucket 3 by a hinge connection. The hinge can provide a sufficient rotation range so that the shielding cover 34 can be freely switched between the closed and open states. In addition, in order to achieve automated control, a temperature or humidity sensor can be installed on the monitoring device. When snow is detected, the sensor will send a signal to the controller, and the controller will then drive the opening mechanism of the shielding cover 34 to operate, thereby achieving automatic opening of the shielding cover 34. When the environmental conditions change to no snow, the sensor will send a signal to close the shielding cover 34. Specifically, the opening and closing of the shielding cover 34 can be achieved by an electric or mechanical linkage system to ensure its stable operation in different environments.

[0045] In one embodiment, the sliding guide rail 4 of the snowfall intensity monitoring device of the present application adopts a two-way locking design to ensure the smoothness and stability of the collection bucket when sliding up and down. One end of the sliding guide rail 4 is fixed to the top mounting platform 13, and the other end is fixed to the top mounting platform 13 by a locking device 41 (such as Figure 4 The snow collecting hopper 3 is secured to the top of the snow collecting hopper 3 (as shown). This design effectively reduces the impact of external wind on the hopper, thereby ensuring accurate data collection. The locking device 41 utilizes a spring-loaded snap-fit ​​structure that automatically locks once the snow collecting hopper 3 reaches a predetermined height, further enhancing the reliability and stability of the device. The spring-loaded snap-fit ​​design effectively prevents loosening due to wind, even in harsh external environments, thereby ensuring stable data collection from the displacement sensor 5.

[0046] Specifically, a sliding rail 4 with fixed ends can be installed between the top mounting platform 13 and the snow collecting hopper 3. Specifically, one end of the sliding rail 4 is secured to the top mounting platform 13 via fasteners, while the other end is secured to the top of the snow collecting hopper 3 via a spring-loaded locking device 41. This spring-loaded locking device 41 comprises a retractable spring and a latch. When the snow collecting hopper 3 is moved to a predetermined position, the latch automatically pops out and secures itself to a specific location on the rail, ensuring the hopper's stability in that position.

[0047] In one embodiment, a device for monitoring snowfall intensity according to the present application features auxiliary guide strips 42 on either side of the sliding rail 4. These strips are made of a low-friction material to prevent the snow collecting bucket 3 from getting stuck due to excessive resistance during sliding, thereby improving response speed. This design optimizes the device's stability and responsiveness, enabling it to maintain good performance even in complex environmental conditions.

[0048] The structure and function of the sliding guide rail 4 are crucial to ensuring smooth sliding of the snow collecting hopper 3. Specifically, the sliding guide rail 4 is mounted on the inner side of the support frame 1 and is flanked by auxiliary guide bars 42. These auxiliary guide bars 42 are made of a low-friction material, effectively reducing friction during sliding and preventing excessive resistance that can cause sticking. Furthermore, the choice of low-friction material helps extend the life of the device and reduce maintenance costs.

[0049] In one embodiment, the auxiliary guide strips 42 can be made of polytetrafluoroethylene (PTFE) or other similar low-friction materials. These materials have excellent self-lubrication and wear resistance, and can maintain a smooth surface during repeated sliding. To further improve the reliability of the device, the auxiliary guide strips 42 can be fixed to both sides of the sliding guide rail 4 through an embedded installation method, so that they fit tightly to the sliding guide rail 4 and ensure that the snow collection bucket 3 can move smoothly along the guide rail. For example, grooves can be provided on both sides of the sliding guide rail 4, and the auxiliary guide strips 42 can be embedded and fixed to ensure stable operation under various working conditions.

[0050] In one embodiment, the height of the sliding rail 4 of a snowfall intensity monitoring device of the present application is at least twice the height of the windshield 2. The provision of the sliding rail 4 enables the snow collection hopper 3 to perform displacement measurements over a wider range of heights, thereby better adapting to varying snowfall conditions and effectively reducing the impact of wind speed on measurement results. The sliding rail 4 is securely connected to the main body of the device, ensuring its stability and reliability in various weather conditions. The required height of the sliding rail 4 allows the snow collection hopper 3 to move freely over a relatively high range, thereby increasing the flexibility and applicability of the monitoring device.

[0051] For example, the specific dimensions of the sliding rails 4 can be determined by adjusting the height of the device body. The sliding rails 4 are connected to the device body via welding or fasteners, ensuring structural stability. The snow collection hopper 3 is connected to the sliding rails 4 via a slider, which slides smoothly on the rails, allowing for snow collection and measurement at various heights. Furthermore, a windshield 2 is mounted above the device body, its height coordinated with the designed height of the sliding rails 4, ensuring the effective operation of the monitoring device in complex meteorological environments.

[0052] In one embodiment, see Figure 3In the present application, a flexible vibration damping tube 51 is provided between the displacement sensor 5 and the wind shield 2 of a monitoring device for snowfall intensity. The main purpose of this design is to reduce the influence of wind on the measurement results and ensure the measurement accuracy of the device in various environments. The flexible vibration damping tube 51 is located between the displacement sensor 5 and the wind shield 2. It can effectively absorb vibration energy under the action of external wind force and prevent wind force from being transmitted to the displacement sensor 5 through the bracket, thereby avoiding or reducing errors caused by wind vibration during the measurement process. This structural improvement not only improves the stability and reliability of the device, but also ensures the accuracy and repeatability of snowfall intensity data.

[0053] For example, the flexible vibration-damping tube 51 is constructed from multiple layers of soft, highly elastic material that deforms when impacted by wind, rapidly converting mechanical energy into heat and other forms of energy dissipation. The displacement sensor 5 is mounted on one end of the vibration-damping tube, while the other end is secured to the internal structure of the windshield 2, creating an effective vibration isolation system. Furthermore, the design of the windshield 2 further optimizes airflow distribution, reducing the impact of localized airflow on the vibration-damping tube and further improving measurement accuracy.

[0054] During actual operation, when this device is in use, the support frame 1 first secures and supports the entire device, ensuring its stability and reliability. A windshield 2 is mounted on the support frame 1, effectively shielding against the effects of strong external winds on snowfall measurements and ensuring the accuracy of internal sensor measurements. As snowfall begins, a snow collection hopper 3, located within the windshield 2, collects snow samples while ensuring that the snowfall is not disturbed by the external environment. To better adapt to snowfall conditions at varying heights, a sliding rail 4 is mounted on the support frame 1 and connected to the snow collection hopper 3. The sliding rail 4 guides the vertical movement of the snow collection hopper 3, reducing the impact of wind on measurement results and ensuring a more accurate reflection of the actual snowfall intensity. A displacement sensor 5 is fixed to one end of the sliding rail 4 and is used to detect the vertical displacement of the snow collection hopper 3 in real time. As snow accumulates, the snow collection hopper 3 moves downward along the sliding rail 4 due to the weight of the accumulated snow. The displacement sensor 5 detects this displacement, indirectly reflecting changes in snowfall intensity. In this way, not only can the mutual interference between the wind speed sensor and the snowfall intensity sensor be effectively avoided, but also high-precision and reliable snowfall intensity data can be provided, thus providing an important reference basis for weather forecasting and disaster prevention.

[0055] The above are only specific embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in this application, and such modifications or substitutions should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
