[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] The technical terms in the embodiments are explained below:

[0025] A wind turbine is a renewable energy device that converts wind energy into electrical energy. The following is a detailed introduction to its working principle, structural composition, application areas, advantages and disadvantages.

[0026] Working principle:

[0027] Wind turbines convert wind energy into mechanical energy, which is then converted into electrical energy by a generator. When wind blows over the turbine's blades, the wind forces them to rotate, driving the entire rotor. The rotor's rotational kinetic energy is transferred to the generator via a transmission system (such as a gearbox). The generator uses electromagnetic induction to convert the mechanical energy into electrical energy. The generated electricity is processed by a controller and inverter to meet grid requirements or stored in batteries.

[0028] Structural composition:

[0029] The rotor, consisting of blades and a hub, is the core component of a wind turbine, responsible for capturing and utilizing the kinetic energy of the wind. The shape and angle of the blades are optimized to maximize wind energy capture efficiency.

[0030] Transmission system: usually composed of gearboxes, bearings, couplings and other components, responsible for transmitting the rotational motion of the wind wheel to the generator, and converting the low-speed rotation of the wind wheel into the high-speed rotation required by the generator.

[0031] Generator: The core component of a wind power generation system, it converts mechanical energy into electrical energy using the principle of electromagnetic induction. The generator consists of a stator and a rotor. As the rotor rotates, it cuts through the magnetic field lines in the stator, generating an induced current in the stator coils.

[0032] Tower: The structure that supports the wind rotor, generator, and other components must be strong and stable enough to withstand wind and other external loads. The tower's height is determined by the impact of ground obstacles on wind speed and the diameter of the wind rotor, and is generally between 6 and 20 meters.

[0033] Control system: Responsible for monitoring environmental parameters such as wind speed and direction, and adjusting the speed of the wind rotor and the output power of the generator based on this information to ensure that the wind power generation system can operate stably and optimize power generation efficiency under various wind conditions.

[0034] Application areas:

[0035] Power industry: Widely used in large wind farms to provide clean, renewable electricity to the power grid.

[0036] Power supply in remote areas: For some remote areas without electricity, small wind turbines can form a power supply system for lighting, television, washing machines and other household electricity, solving the electricity problem in these areas.

[0037] Construction and transportation fields: Provide reliable power supply for independent power supply of villas, grid-connected power supply on roofs of public buildings, and infrastructure such as street lights, road monitoring, navigation lights, traffic lights, gas stations, toll booths and other public places.

[0038] Communications field: as part of the power supply system of communication base stations, microwave relay stations, and optical cable maintenance stations.

[0039] Other fields: It also plays an important role in major fields such as petrochemicals, ocean, meteorology, security and national defense, such as power supply for oil and gas pipeline security monitoring systems, emergency backup power supply for oil drilling platforms, fishing boat life power supply systems, marine communication power supply systems, small seawater desalination equipment power supply systems, offshore aquaculture power supply systems, meteorological monitoring station power supply systems, hydrological observation equipment power supply systems, border monitoring power supply systems, etc. In the field of agriculture, forestry and water conservancy, solar insect killer lamps, forest fire prevention monitoring systems, flood control dike roads and landscape lighting systems also need power support, and this part of the electricity can be provided by small wind turbines.

[0040] Clean and environmentally friendly: The power generation process does not require fuel, has no radiation, and does not produce air pollution. It is a clean energy.

[0041] Renewable: Wind energy is a renewable energy source that is inexhaustible. Using wind energy to generate electricity can reduce dependence on traditional fossil energy, reduce carbon emissions, and comply with the concept of sustainable development.

[0042] Short construction period: Compared with traditional power plants, the construction period of wind farms is relatively short and they can be put into use more quickly.

[0043] Flexible installed capacity scale: The installed capacity scale of wind turbines can be adjusted according to actual needs. Large-scale wind farms can be built, and small wind turbines can be installed to meet local electricity needs.

[0044] A rain and snow sensor is a device used to detect precipitation type (rain or snow) and precipitation intensity. It plays an important role in modern meteorological monitoring, traffic management, agricultural irrigation and other fields. The following is a detailed introduction to it:

[0045] Working principle:

[0046] Capacitive sensing principle: The sensor's sensing surface is like the plate of a capacitor. When there's no precipitation, the capacitance remains stable. When rain or snow falls on the sensing surface, the capacitance changes because the dielectric constant of water (or melted snow) is different from that of air. The more precipitation there is, the greater the change in capacitance. By detecting this change in capacitance, precipitation can be determined.

[0047] Electrical principle: The sensor surface is covered with conductive material. When raindrops or snowflakes touch the surface, it causes an electric current to flow. By detecting this current change, the sensor can determine the presence and intensity of rain and snow.

[0048] Optical Principle: The sensor typically consists of a pair of photodiodes, a transmitter, and a receiver. The transmitter sends an infrared beam, while the receiver receives the reflected light signal. When raindrops or snowflakes pass through the beam, they scatter some of the light, causing the light intensity received by the receiver to change. Based on this change in received light intensity, the sensor can determine the presence and intensity of rain or snow.

[0049] Features:

[0050] High Precision: Able to accurately detect the intensity and amount of precipitation and snowfall, improving the accuracy of weather forecasts.

[0051] Good stability: It has good stability and reliability and can work in harsh environments such as high temperature, low temperature, high humidity, strong wind, etc.

[0052] Easy maintenance: Simple structure, small size, and light weight make it easy to maintain and replace. At the same time, its shell material has good sealing properties, which can prevent moisture and dust from entering the interior and affecting the normal operation of the sensor.

[0053] Strong adaptability: It can adapt to different application scenarios by adjusting parameters such as sensitivity and response time.

[0054] High protection level: Some rain and snow sensors have an IP68 protection level design and can work outdoors for a long time.

[0055] Various transmission modes: Supports multiple data transmission modes, such as 485, relay output, etc., which is convenient for connection with host computer or other devices.

[0056] Optional heating function: In snowy conditions, when the temperature is below 0°C for a long time, or in high humidity environments, the grid will automatically heat up to prevent data deviations caused by icing and condensation.

[0057] Low power consumption: Some sensors are designed with a low power consumption mode, which can extend battery life and reduce maintenance costs while ensuring monitoring accuracy.

[0058] Strong anti-interference ability: built-in automatic heating device can eliminate the interference of rain and snow adhering to the sensor surface, ensuring the accuracy and stability of data.

[0059] Reference Figures 1 to 2As shown, the present invention provides a precipitation sample collection device suitable for high-altitude glacier areas, including an insulated box 3, a support assembly is provided at the bottom end of the insulated box 3, the interior of the insulated box 3 is divided into an upper chamber and a lower chamber by a partition 5, the top wall of the upper chamber is provided with a collecting funnel 7, the discharge end of the collecting funnel 7 is connected to a heat pipe 19, the heat pipe 19 extends into the upper chamber and is provided with a heating assembly, the heating assembly is electrically connected to a controller, a sampling bottle 6 is placed in the upper chamber, the sampling bottle 6 is arranged corresponding to the heat pipe 19, a scraper assembly is provided in the collecting funnel 7, a rain and snow sensor 29 is provided in the collecting funnel 7, the rain and snow sensor 29 is electrically connected to the controller, a battery 4 is provided in the lower chamber, a wind power generation device is provided on the outside of the insulated box 3, the wind power generation device and the controller are electrically connected to the battery 4, and the wind power generation device is transmission-coordinated with the scraper assembly.

[0060] The entire sampling device is stably supported by the support assembly to prevent it from being blown down by strong winds. The wind power generation device is set up, which can not only drive the scraper assembly to rotate, but also generate electricity and store it in the battery 4 to provide power for the heating assembly. The scraper assembly can scrape off the snow remaining on the inner wall of the collection funnel 7, so that it can pass smoothly through the heat pipe 19 into the sampling bottle 6 to complete the sampling. In addition, the rain and snow sensor 29 can monitor the snowfall and transmit the information to the controller. The controller controls the operation of the heating assembly to heat the heat pipe 19; prevent the snowfall from freezing at the heat pipe 19 and causing blockage, thereby ensuring smooth sampling.

[0061] Furthermore, the wind power generation device includes a column 17 fixed on the ice surface, and a wind turbine 12 is provided on the top of the column 17. The wind turbine 12 is driven and matched with the scraper assembly through a transmission assembly.

[0062] The column 17 is fixed by drilling holes in the ice surface with a steam drill, and the wind turbine 12 generates electricity by means of wind power and drives the scraper assembly to rotate through the transmission assembly.

[0063] Furthermore, the scraper assembly includes two brackets 24 horizontally connected to the inner wall of the collecting funnel 7, and a rotating rod 26 is rotatably connected between the brackets 24. The rotating rod 26 is coaxially arranged with the collecting funnel 7. The rotating rod 26 is elastically connected to the scraper 25 through two springs 27. The scraper 25 is inclined and in friction contact with the inner wall of the collecting funnel 7. A plurality of hemispheres 21 are circumferentially arranged on the inner wall of the collecting funnel 7, and the hemispheres 21 are in friction contact with the scraper 25.

[0064] The wind turbine 12 drives the rotating rod 26 to rotate through the transmission assembly. The rotating rotating rod 26 drives the spring 27 and the scraper 25 to slide along the inner wall of the collecting funnel 7. When the scraper 25 encounters the obstruction of the hemisphere 21, the spring 27 is twisted and deformed, thereby enabling the scraper 25 to slide through the hemisphere 21. Then the spring 27 recovers, and the scraper 25 swings to move the snowfall, making it easier to break up the accumulated snow so that it can smoothly enter the heat pipe 19 at the bottom of the collecting funnel 7 and finally smoothly enter the sampling bottle 6.

[0065] Since the wind turbine 12 is in transmission coordination with the scraper assembly, the scraper assembly can automatically rotate for cleaning under the action of wind without manual intervention, thus realizing a linkage cleaning mechanism and improving the degree of automation and practicality of the device.

[0066] Furthermore, the transmission assembly includes a chain box 11 fixedly connected to the column 17, one end of the rotating shaft of the wind turbine 12 extends into the chain box 11 and is connected to the driving sprocket 10, a bracket 16 is connected to the outer wall of the insulation box 3, and a rotating shaft 15 is rotatably connected to the bracket 16, one end of the rotating shaft 15 extends into the chain box 11 and is connected to the driven sprocket 14, and the driven sprocket 14 is transmitted and matched with the driving sprocket 10 through a chain, and the other end of the rotating shaft 15 passes through the side wall of the collecting funnel 7 and is connected to the driving bevel gear 22, and the top of the rotating rod 26 is connected to the driven bevel gear 23, and the driven bevel gear 23 is transmitted and matched with the driving bevel gear 22.

[0067] The chain box 11 can prevent snow from falling on the chain and freezing, thereby ensuring the effectiveness of the chain transmission.

[0068] The wind turbine 12 rotates with the help of wind power, and at the same time, the driving sprocket 10 is driven to rotate through the rotating shaft of the wind turbine 12. The driving sprocket 10 drives the driven sprocket 14 to rotate through the chain. The rotating driven sprocket 14 drives the rotating shaft 15 and the driving bevel gear 22 to rotate. The driving bevel gear 22 and the driven bevel gear 23 are engaged with each other, and the rotating rod 26 is driven to rotate, thereby realizing the rotation of the scraper assembly.

[0069] Furthermore, the heating assembly includes a heating wire 20 fixedly wound around the outer wall of the heat conducting tube 19 , and a heat insulation layer is wound around the heating wire 20 .

[0070] In this embodiment, the insulation layer is a hard polyurethane, which is not only scratch-resistant but also has a good insulation effect. The heat is generated by the heating wire 20 to heat the heat pipe 19. The heat pipe 19 is made of copper and has good thermal conductivity. Snow or ice accumulated on the heat pipe 19 can be melted by heat conduction and slide into the sampling bottle 6.

[0071] Furthermore, the bottom end of the rotating rod 26 is connected to one end of the cross bar 28 , and the other end of the cross bar 28 is connected to the elastic scraper 18 , and the elastic scraper 18 is in friction contact with the inner wall of the heat pipe 19 .

[0072] The elastic scraper 18 is driven to rotate by the rotating rod 26 to scrape away the snow or ice on the inner wall of the heat conducting pipe 19 .

[0073] Furthermore, the support assembly includes a plurality of support legs 2 fixedly connected to the bottom end of the heat preservation box 3 at equal intervals. The support legs 2 are arranged at an angle, and a plurality of counterweight rings 1 are slidingly sleeved on the support legs 2.

[0074] By fixing and connecting a plurality of tilted support legs 2 at equal intervals at the bottom end of the insulated box 3, the overall stability of the device is effectively increased, and it can better withstand adverse weather conditions such as strong winds that may occur in high-altitude glacial areas, and prevent the device from tipping over. The tilted support legs 2 can increase the contact area between the support feet and the ground and the distribution of the fulcrums, which helps the device maintain stability on uneven or soft ground and adapt to the complex and changeable terrain environment of high-altitude glacial areas. In addition, a plurality of counterweight rings 1 are slidably mounted on the support legs 2, and the number and position of the counterweight rings can be adjusted according to actual needs, so as to flexibly change the weight distribution of the device, further enhance the stability of the device, and also facilitate the adjustment of the counterweight according to actual conditions during transportation or installation.

[0075] Furthermore, in order to provide a dual-energy power generation mode and ensure that the battery 4 has sufficient power, a solar panel 13 is provided on the top of the column 17 , and the solar panel 13 is electrically connected to the battery 4 .

[0076] In this embodiment, the battery 4 is charged by a wind-solar hybrid charging controller.

[0077] Furthermore, the main body of the sampling bottle 6 is a double-layer stainless steel structure, wherein the inner wall of the sampling bottle 6 is provided with Teflon, and the interlayer of the sampling bottle 6 is vacuum-treated and filled with aerogel felt.

[0078] The interlayer of sampling bottle 6 is vacuum-treated and filled with aerogel felt. The vacuum treatment effectively isolates most heat conduction, while the aerogel felt, a highly effective thermal insulation material with extremely low thermal conductivity, further inhibits heat transfer. This design provides the sampling bottle with excellent thermal insulation properties. In extreme low-temperature environments such as high-altitude glacial regions, it effectively reduces the impact of external low temperatures on the temperature of the precipitation sample inside the bottle, preserving the sample's original state and effectively reducing the impact of external factors on the sample, thereby ensuring the quality of the precipitation sample and the accuracy of the analysis results.

[0079] Furthermore, the inner wall of the heat preservation box 3 is paved with an electric heating wire mesh, which is connected to the controller, and a polyurethane insulation layer is provided on the surface of the electric heating wire mesh.

[0080] In this embodiment, electric heating networks are arranged in the upper and lower chambers of the thermal insulation box 3, and temperature sensors are provided. The temperature sensors transmit the monitored temperature data to the controller. The controller controls the heating power and heating time of the electric heating networks in the two chambers according to the preset threshold, thereby realizing precise adjustment of the temperature in the thermal insulation box. On the one hand, it ensures that the battery 4 can be used normally, and on the other hand, it provides a suitable temperature environment for the collection and storage of precipitation samples.

[0081] Furthermore, a guide plate 9 is fixedly connected at an angle to the top of the collecting funnel 7. The guide plate 9 is a conical structure, and an entrance is radially opened from the center of the guide plate 9. A baffle 8 is rotatably connected to the entrance. The rotating shaft sleeve of the baffle 8 is provided with a torsion spring, and the two ends of the torsion spring are respectively against the guide plate 9 and the baffle 8.

[0082] The torsion spring is set to keep the baffle 8 in a normally closed state, thereby effectively blocking the entrance and preventing foreign matter from entering the collection funnel 7 and causing pollution to the precipitation sampling. When snow falls, the snow accumulates preferentially at the conical bottom end of the guide plate 9. When the gravity of the accumulated snow is greater than the elastic force of the torsion spring, the baffle 8 rotates. At this time, the blockage of the entrance fails and the accumulated snow enters the collection funnel 7.

[0083] The precipitation sample collection device provided by the present invention is suitable for high-altitude glacier areas. Its working principle is as follows: when in use, the device of the present invention is fixed at the target position. When snowfall occurs, the snow is first accumulated at the conical bottom end of the guide plate 9. When the gravity of the accumulated snow is greater than the elastic force of the torsion spring, the baffle 8 rotates. At this time, the blockage of the entrance fails, and the accumulated snow enters the collection funnel 7. The rain and snow sensor 29 can monitor the snowfall and transmit the information to the controller. The controller controls the operation of the heating component to heat the heat pipe 19. The wind turbine 12 drives the rotating rod 26 to rotate through the transmission component. The rotating rotating rod 26 drives the spring 27 and the scraper 25 to slide along the inner wall of the collection funnel 7. When the scraper 25 encounters the obstruction of the hemisphere 21, the spring 27 is twisted and deformed, thereby realizing the scraper 25 from the hemisphere. The body 21 slides over, and then the spring 27 recovers, and the scraper 25 swings to move the snow, so as to break up the accumulated snow and allow it to smoothly enter the heat pipe 19 at the bottom of the collecting funnel 7. At the same time, the rotating rod 26 drives the elastic scraper 18 to rotate, thereby scraping off the snow or ice on the inner wall of the heat pipe 19 and finally smoothly entering the sampling bottle 6 to complete the collection; the wind turbine 12 and the solar panel 13 perform dual-energy power generation and charge the battery 4 through the wind-solar complementary charging controller to ensure that the battery 4 has sufficient electrical energy. The battery 4 provides electrical energy for the heating wire 20, and the heating wire 20 generates heat to heat the heat pipe 19, so that the snow or ice at the heat pipe 19 is melted by heat conduction and slides into the sampling bottle 6 to prevent blockage at the heat pipe 19, thereby ensuring smooth sampling.
