Description

Technical Field

[0001] The utility model relates to the technical field of droplet spectrometers, and more specifically, to a sampling device for droplet spectrometers. Background Art

[0002] A sampling device for a droplet spectrometer is a device specially designed for collecting droplet samples in fog. The device can efficiently capture droplets of different sizes and concentrations and import them into the droplet spectrometer for precise measurement, thereby obtaining key parameters such as the size distribution and number concentration of the droplets. When designing, factors such as wind speed and sampling efficiency need to be considered to ensure accurate and error-free sampling. At the same time, the compatibility of the device with the droplet spectrometer is crucial to ensure that the samples are smoothly imported into the instrument for analysis.

[0003] Existing droplet spectrometers mostly rely on the duct tube sampling method, the principle of which is to collect air at a fixed height of the duct tube closely connected to the instrument and in a small area around the duct tube at that height. Although this method can reflect the characteristics of droplets to a certain extent, due to its limitations, it can only provide the average droplet conditions at a fixed height and within a limited range. However, the local characteristics of radiation fog are extremely significant, and the thickness and microphysical characteristics of fog may vary significantly at different heights and different locations at the same height. Therefore, this sampling method is difficult to fully reflect the actual fog conditions at a specific location, and has certain limitations for refined droplet observation and research. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. Compared with the traditional device, the utility model facilitates the adjustment of the height of the sampling and collecting head through the cooperation between the first tooth and the second tooth, and can more accurately measure the characteristics of different fog layers. There are differences in the size and concentration of the droplets of radiation fog in the vertical direction. Adjusting the height helps to fully understand its vertical structure. At the same time, it avoids the droplets near the ground that are disturbed by the surface temperature, humidity and vegetation, so that purer samples can be obtained. Appropriate adjustment of the height of the sampling and collecting head can also ensure that it is in the best working position and improve the measurement accuracy. In addition, the height adjustment function of the droplet spectrometer also enables it to flexibly respond to different observation needs and provide researchers with more valuable droplet characteristic data.

Compared with the traditional device, the utility model facilitates sampling at the same height and in different directions through the cooperation between the half gear and the tooth three, which helps to fully understand the droplet distribution characteristics of the radiation fog at this height level. Due to differences in wind direction and terrain, there may be significant differences in droplet distribution. By sampling in different directions with the sampling collection head, the droplet spectrometer can capture these subtle changes and more accurately depict the overall characteristics of the fog. At the same time, this sampling method helps to discover the law of droplet flow and reveal its formation and dissipation mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5 As shown, the utility model provides a sampling device for a droplet spectrometer, including a workbench 1, a turntable 2 is movably installed inside the workbench 1, a box body 3 is fixedly installed on the top of the turntable 2, a threaded sleeve 4 is movably installed inside the box body 3, a threaded rod 20 is sleeved on the internal thread of the threaded sleeve 4, a tooth 21 is fixedly installed at one end of the threaded rod 20, the tooth 21 is meshed with the tooth 22, a connecting rod 8 is fixedly installed inside the tooth 22, and both ends of the connecting rod 8 completely penetrate the inside of the box body 3, and a manual rocker 7 is fixedly installed at one end of the connecting rod 8;

[0023] A platform 19 is installed on the top of the threaded sleeve 4, and a folding tube 5 is fixedly installed on the top of the platform 19. A sampling and collecting head 11 is fixed at one end of the folding tube 5, and the other end of the folding tube 5 is fixedly connected to the air inlet of the air pump 6. A droplet spectrometer 13 is fixedly installed on the top of the workbench 1, and the droplet spectrometer 13 and the air pump 6 are fixedly connected by a connecting pipe 25.

[0024] The staff needs to sample the radiation fog at different heights in the same direction. By turning on the air pump 6, the radiation fog slowly enters the folding tube 5 through the sampling and collecting head 11, and then slowly enters the inside of the connecting tube 25 through the folding tube 5, and then enters the inside of the droplet spectrometer 13 through the connecting tube 25 for detection. Now hold the joystick 7 by hand, and drive the connecting rod 8 to rotate inside the box 3 through the manual joystick 7, and then drive the tooth 22 to rotate through the connecting rod 8, and through the tooth meshing between the tooth 22 and the tooth 1 21, drive the tooth 1 21 to rotate through the tooth 22, and then drive the threaded rod 20 inside the threaded sleeve 4 through the tooth 1 21, so that the threaded sleeve 4 slowly raises the platform 19, and then drives the sampling and collecting head 11 and the folding tube 5 to slowly raise through the platform 19. Finally, repeat the above steps to complete the sampling of radiation fog at different heights in the same direction.

[0025] It is necessary to sample radiation fog at different heights in the same direction. By turning on the air pump 6, the radiation fog slowly enters the folding tube 5 through the sampling and collecting head 11, and then slowly enters the inside of the connecting tube 25 through the folding tube 5, and then enters the inside of the droplet spectrometer 13 through the connecting tube 25 for detection. Now hold the joystick 7 by hand, and drive the connecting rod 8 to rotate inside the box 3 through the manual joystick 7, and then drive the tooth 22 to rotate through the connecting rod 8, and through the tooth meshing between the tooth 22 and the tooth 1 21, drive the tooth 1 21 to rotate through the tooth 22, and then drive the threaded rod 20 inside the threaded sleeve 4 through the tooth 1 21, so that the threaded sleeve 4 slowly raises the platform 19, and then drives the sampling and collecting head 1 through the platform 19. 1 and the folding tube 5 are slowly raised, and the above steps are repeated. Compared with the traditional device, the device facilitates the adjustment of the height of the sampling and collecting head 11 through the cooperation between the tooth 1 21 and the tooth 2 22, and can more accurately measure the characteristics of different fog layers. There are differences in the droplet size and concentration of radiation fog in the vertical direction. Adjusting the height is helpful to fully understand its vertical structure. At the same time, it avoids the droplets near the ground that are disturbed by the surface temperature, humidity and vegetation, so that a purer sample can be obtained. The appropriate adjustment of the height of the sampling and collecting head 11 can also ensure that it is in the best working position and improve the measurement accuracy. In addition, the height adjustment function of the droplet spectrometer 13 also enables it to flexibly respond to different observation needs and provide researchers with more valuable droplet characteristic data.

[0026] Among them, a box body 26 is fixedly installed at the bottom of the workbench 1, a connecting column 23 is fixedly installed at the bottom of the turntable 2, and the connecting column 23 is movably installed inside the box body 26, a motor 14 is fixedly installed at one end of the box body 26, a half gear 24 is fixedly installed at one end of the motor 14, and the half gear 24 is meshed with the gear three 27.

[0027] After the staff completes the sampling of radiation fog at different heights in the same direction, it is necessary to sample the radiation fog at the same height but in different directions. The motor 14 is turned on to drive the half gear 24 to rotate inside the tooth 22 through the motor 14. The tooth meshing between the half gear 24 and the tooth 3 27 drives the tooth 3 27 to rotate through the half gear 24. The turntable 2 is driven to rotate on the workbench 1 through the connecting column 23. The box 1 3 and the sampling collection head 11 are driven to rotate through the tooth 2 22, thereby completing the sampling of the radiation fog at the same height but in different directions.

[0028] After the radiation fog sampling at different heights in the same direction is completed, the radiation fog needs to be sampled at the same height but in different directions. The motor 14 is turned on, and the motor 14 drives the half gear 24 to rotate inside the tooth 22. The tooth meshing between the half gear 24 and the tooth 3 27 drives the tooth 3 27 to rotate through the half gear 24. The turntable 2 is driven to rotate on the workbench 1 through the connecting column 23, and the box 1 3 and the sampling and collecting head 11 are driven to rotate through the tooth 22. Compared with the traditional device, the device facilitates the sampling of the same height but in different directions through the cooperation between the half gear 24 and the tooth 3 27. This helps to fully understand the droplet distribution characteristics of the radiation fog at this height level. Due to differences in wind direction and terrain, there may be significant differences in droplet distribution. By sampling in different directions with the sampling and collecting head, the droplet spectrometer 13 can capture these subtle changes and more accurately depict the overall characteristics of the fog. At the same time, this sampling method helps to discover the law of droplet flow and reveal its formation and dissipation mechanism.

[0029] Among them, the platform 19 and the top of the box body 3 are fixedly installed with telescopic rods 12, and the telescopic rods 12 present four shapes of the same size.

[0030] Since the telescopic rod 12 presents four shapes of the same size, the platform 19 and the sampling and collecting head 11 are more stable when rising, and the shaking of the sampling and collecting head 11 during the sampling process is avoided, thereby improving the sampling efficiency of the sampling and collecting head 11.

[0031] A limiting groove 18 is provided inside the workbench 1 , and a tool box 17 is movably installed inside the limiting groove 18 .

[0032] By holding the toolbox 17, the toolbox 17 is slowly placed into the limiting groove 18, and the limiting groove 18 is fixed by the toolbox 17. By adding the toolbox 17, the operator can quickly find the required tools, reduce the time of searching and organizing tools, and thus speed up the progress of sampling work.

[0033] A motor protection cover 15 is movably mounted on the outer surface of the motor 14 , and heat dissipation holes are provided inside the motor protection cover 15 . A fixing bracket 16 is fixedly mounted on the bottom of the motor protection cover 15 .

[0034] Through the cooperation between the motor protection cover 15 and the fixing bracket 16, the motor 14 is supported by the fixing bracket 16, which improves the stability of the motor 14 during operation. The motor protection cover 15 dissipates heat inside the motor 14, thereby extending the service life of the motor 14.

[0035] A support plate 9 is fixedly installed at the bottom of the workbench 1 , and a support column 10 is fixedly installed between two support plates 9 .

[0036] The cooperation between the support column 10 and the support plate 9 facilitates the support of the entire device, ensuring that the sampling device is more stable during the sampling process, ensuring that the sampling device of the connecting tube 25 remains stable during operation, and preventing shaking or displacement caused by external factors, thereby ensuring the accuracy and reliability of the sampling data.

[0037] The working principle and use process of this utility model:

[0038] The staff needs to sample the radiation fog at different heights in the same direction. By turning on the air pump 6, the radiation fog slowly enters the folding tube 5 through the sampling and collecting head 11, and then slowly enters the inside of the connecting tube 25 through the folding tube 5, and then enters the inside of the droplet spectrometer 13 through the connecting tube 25 for detection. Now hold the joystick 7 by hand, and drive the connecting rod 8 to rotate inside the box 3 through the manual joystick 7, and then drive the tooth 22 to rotate through the connecting rod 8, and through the tooth meshing between the tooth 22 and the tooth 1 21, drive the tooth 1 21 to rotate through the tooth 22, and then drive the threaded rod 20 inside the threaded sleeve 4 through the tooth 1 21, so that the threaded sleeve 4 slowly raises the platform 19, and then drives the sampling and collecting head 11 and the folding tube 5 to slowly raise through the platform 19. Finally, repeat the above steps to complete the sampling of radiation fog at different heights in the same direction.

[0039] After the staff completes the sampling of radiation fog at different heights in the same direction, it is necessary to sample the radiation fog at the same height but in different directions. The motor 14 is turned on to drive the half gear 24 to rotate inside the tooth 22 through the motor 14. The tooth meshing between the half gear 24 and the tooth 3 27 drives the tooth 3 27 to rotate through the half gear 24. The turntable 2 is driven to rotate on the workbench 1 through the connecting column 23. The box 1 3 and the sampling collection head 11 are driven to rotate through the tooth 2 22, thereby completing the sampling of the radiation fog at the same height but in different directions.
