Description

Technical Field

[0001] This utility model relates to the field of dust storm collection and monitoring equipment, specifically to a butterfly-shaped dust storm concentration level flux real-time dynamic collection and monitoring device. Background Technology

[0002] Dust storms are large-scale transport processes of fine-grained material produced by wind erosion of the earth's surface under the influence of strong air currents. The dust storm process includes the release of erosive surface dust into the atmosphere, the transport of dust in air currents, and the deposition of dust. The formation of the Loess Plateau in China and the distribution of loess deposits across the world's continents over millions of years demonstrate that dust storms are a biogeochemical cycle on Earth. However, the indiscriminate reclamation and utilization of land by humans has led to large-scale desertification, intensifying dust storm activity and causing frequent disasters. The arid inland northwest of my country is widely covered by deserts, Gobi, and desertified lands. Their dry, loose surfaces and lack of vegetation cover objectively provide favorable conditions for dust storms, making it a major source area for dust storms in my country historically.

[0003] To study methods for controlling sandstorms, the horizontal flux of sand is a very important physical quantity. Therefore, it is necessary to study the relationship between wind speed, wind direction and sand in scientific experiments. To this end, it is necessary to deploy instruments at multiple points and in all directions at the sandstorm site to collect sand flux data, so as to observe wind, sand flow and sand transport volume, in order to conduct research and engineering calculations on sand flow in sandstorms.

[0004] A utility model patent entitled "A Wind-Powered Rotary Centrifugal Dust Collector" is disclosed in CN209656365U. It comprises a conical cylinder and a cylindrical cylinder, with the conical cylinder being shaped like a conical funnel. The cylindrical cylinder has a sand inlet that cuts into the inner edge of the cylinder. Wind vanes and directional indicators are installed on both sides of the middle section. A centrifugal propeller is fixed to a hollow cylindrical tube at the top of the cylindrical cylinder. The hollow cylindrical tube passes through the cylindrical cylinder and is connected to the wind cup rotating bearing and the wind cup. There is an exhaust hole at the top of the hollow cylindrical tube. The bottom of the conical cylinder has a dust collection nozzle. The conical cylinder sits on a rotating support with a wind vane rotating bearing. The rotating support is connected to a fixed support flange on a gradient tower. A protective box is installed below the rotating support, and the box contains a sand collection cup, which is directly opposite the dust collection nozzle.

[0005] While the aforementioned patent can collect the horizontal flux of dust suspension at high altitudes per unit area per unit time during a sandstorm, the sand collection cup needs to be removed from the protective box and the collected sand sample weighed before the sand transport rate can be measured and calculated. This method cannot monitor and automatically read data in real time, and cannot achieve long-term, fixed-point collection of dust particle concentration per unit area per unit time at different heights and directions under unattended conditions or specific sandstorm environments. Furthermore, some sand will remain as it falls from the sand inlet through the conical funnel into the sand collection cup, resulting in a significant deviation in the weight of the sand in the collection cup, which further affects the measurement and calculation of the sand transport rate.

[0006] To address the aforementioned issues, this invention provides a butterfly-shaped dust storm concentration level flux real-time dynamic acquisition and monitoring device. Summary of the Invention

[0007] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a butterfly-type dust storm concentration level flux real-time dynamic acquisition and monitoring device. This addresses the problems mentioned in the background technology: when measuring and calculating the sand transport rate, the sand collection cup needs to be removed from the protective box to weigh the collected sand sample; real-time monitoring and automatic data reading are not possible; and it is impossible to collect the concentration of dust particles per unit area per unit time at different heights and orientations under long-term, fixed-point conditions, unattended conditions, or specific dust storm environments. Furthermore, sand may remain as it falls from the sand inlet through the conical funnel into the sand collection cup, causing significant deviations in the weight of the sand in the collection cup, which further affects the measurement and calculation of the sand transport rate.

Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. The structural contents mentioned in the following embodiments are all with reference to the accompanying drawings.

[0037] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0038] Example 1: As shown in the attached document Figures 1 to 10As shown, a real-time dynamic acquisition and monitoring device for the concentration level flux of a butterfly-shaped sandstorm includes a fixed protective cylinder 1, a high-precision weighing sensor 2 installed at the bottom inner part of the fixed protective cylinder 1, a sand collection mechanism 3 installed on the high-precision weighing sensor 2, a circular tube shaft 5 connected to the upper end face of the fixed protective cylinder 1 via a lower fixed bearing 4, a rotating sand and dust separation cylinder 7 connected to the upper part of the circular tube shaft 5 via an upper rotating bearing 6, a wind and sand separation pipe 8 fixedly connected to the center of the inner top of the rotating sand and dust separation cylinder 7, a drive motor 9 installed at the outer top of the rotating sand and dust separation cylinder 7, a drive shaft 10 rotatably connected to the output end of the drive motor 9, a drive gear 11 fixedly connected to the drive shaft 10, and an installation ring 13 fixedly connected to the upper inner wall of the wind and sand separation pipe 8 via a connecting block 12. Four half-gears 14 are evenly and rotatably mounted on the mounting ring 13, and the four half-gears 14 can mesh with the drive gear 11; a sliding rack 15 that can cooperate with the half-gears 14 is provided on the side of the four half-gears 14, and a vibrating slider 16 is fixedly connected to the sliding rack 15; a spring connecting block 17 is fixedly provided on the inner top wall of the rotating sand and dust separation cylinder 7, and the spring connecting block 17 is sleeved on the drive shaft 10; a return spring 18 is fixedly connected to the side of the vibrating slider 16 near the drive shaft 10, and the other end of the return spring 18 is fixedly connected to the spring connecting block 17; a spiral blade 19 is mounted on the drive shaft 10; multiple scraper blades 20 are connected to the bottom of the drive shaft 10; and a wind direction adjustment mechanism 21 is fixedly installed on the outer bottom of the rotating sand and dust separation cylinder 7.

[0039] Further description: In this invention, a plurality of connecting blocks 12 are fixedly installed on the outer circumference of the mounting ring 13; and the other end of the plurality of connecting blocks 12 is fixedly connected to the inner wall of the wind-sand separation pipe 8; four gear shafts 22 are rotatably installed on the mounting ring 13, and a half gear 14 is fixedly connected to each gear shaft 22; a sliding groove 23 is provided on the mounting ring 13 at a position corresponding to the sliding rack 15; the sliding rack 15 is in the shape of an "U", and the bottom of the sliding rack 15 is located in the sliding groove 23.

[0040] When the drive motor 9 is working, the drive shaft 10 connected to its output end starts to rotate. The drive gear 11 fixedly connected to the drive shaft 10 rotates synchronously. The four half gears 14 meshing with the drive gear 11 rotate synchronously in the opposite direction to the drive gear 11. A sliding rack 15 meshes on one side of the half gear 14. When the half gear 14 rotates, it drives the sliding rack 15 to move in the slide groove 23, which further drives the vibrating slider 16 to move towards the inner wall of the sand-air separation pipe 8 and collide with it. The outer edge of the vibrating slider 16 is covered with rubber to prevent excessive collision between the vibrating slider 16 and the sand-air separation pipe 8. When the vibrating slider 16 contacts and collides with the sand-air separation pipe 8, the half gear 14 rotates to the position where it separates from the sliding rack 15. Then, under the action of the return spring 18, the sliding rack 15 drives the vibrating slider 16 to move along the slide groove 23 towards the drive shaft 10 and move closer to it, that is, the vibrating slider 16 moves away from the sand-air separation pipe 8.

[0041] Further description: A centrifugal dust inlet 24 is provided on the upper side of the rotating dust separation cylinder 7; a sand separation exhaust pipe 25 is connected to one side of the sand separation pipe 8; an exhaust port 26 is provided on the rotating dust separation cylinder 7 at a position corresponding to the sand separation exhaust pipe 25; the other end of the sand separation exhaust pipe 25 is connected to the exhaust port 26; and a high-mesh exhaust dust barrier net 27 is provided on the inner wall of the sand separation pipe 8 at a position corresponding to the exhaust port 26.

[0042] Further description: a stainless steel conical tube 28 is provided inside the rotating sand and dust separation cylinder 7; the centrifugal sand and dust inlet 24 cuts into the inner wall edge of the rotating sand and dust separation cylinder 7 and communicates with the stainless steel conical tube 28; the lower end of the stainless steel conical tube 28 is connected to the circular tube shaft 5.

[0043] Further description: a plurality of scraper connecting rods 29 are fixedly connected to the bottom of the drive shaft 10, and a scraper 20 is fixedly connected to the other end of the scraper connecting rod 29, and the scraper 20 is in contact with the inner wall of the stainless steel tapered tube 28.

[0044] Further description: A lower fixed bearing sleeve 30 is provided on the lower fixed bearing 4, and a lower bearing fixing cover 31 is provided on the lower fixed bearing sleeve 30. The lower bearing fixing cover 31 is connected to the fixing protective cylinder 1 through upper and lower connecting buckles 32.

[0045] Further description: the sand collection mechanism 3 includes a protective weighing bottle cylinder 33 mounted on the high-precision weighing sensor 2; a sand collection cup 34 is provided inside the protective weighing bottle cylinder 33; and the lower end of the circular tube shaft 5 extends into the sand collection cup 34.

[0046] Dust enters the interior of the rotating dust separator 7 through the centrifugal dust inlet 24. Since the rotating dust separator 7 is installed by rotating the upper rotating bearing 6, the dust moves in a spiral shape from top to bottom towards the bottom of the stainless steel conical tube 28 after entering the rotating dust separator 7, forming a descending outer swirling dust-laden airflow. This causes the dust-laden airflow to accelerate and generate centrifugal force, throwing the dust particles, which are much denser than gas, towards the cylinder wall. Once the dust particles come into contact with the cylinder wall, they lose inertia and rely on the momentum of the inlet velocity and their own gravity. The separated dust falls down along the wall of the stainless steel conical tube 28 and enters the sand collection cup 34 inside the protective weighing bottle cylinder 33 through the circular tube shaft 5. After reaching the bottom of the stainless steel conical tube 28, the rotating and descending airflow rises along the circular tube shaft 5, forming an ascending inner swirling airflow. The wind-sand separation pipe 8 inside the rotating dust separator 7 discharges the airflow through the wind-sand separation exhaust pipe 25. The high-mesh exhaust dust barrier 27 blocks the dust in the dust-laden airflow from being discharged.

[0047] Further description: a wind vane indicator screw 35 is connected to the bottom of the rotating sand and dust separation cylinder 7 by a fastening nut; an adjustable counterweight 36 is connected to one end of the wind vane indicator screw 35; a fixed wind vane screw 37 is connected to the other end of the wind vane indicator screw 35; and a butterfly wind vane rudder 38 is connected to the other end of the fixed wind vane screw 37.

[0048] The butterfly-shaped wind vane 38 ensures that the centrifugal sand inlet 24 always faces the direction of the horizontal sand flow under the action of wind.

[0049] Further description: A flange 39 is installed at the bottom of the fixed protective cylinder 1. The fixed protective cylinder 1 is fixedly installed on the horizontal support square tube 40 through the flange 39. The horizontal support square tube 40 is fixedly installed on the combined triangular tower 41.

[0050] Further description: A support rod 42 is fixedly installed on the top of the rotating sand and dust separation cylinder 7 and on one side of the drive motor 9. Multiple fan blades 43 are rotatably connected to the upper end of the support rod 42. Two touch-sensitive push switches 44 are symmetrically arranged on the drive motor 9 near the support rod 42. When the fan blades 43 rotate, they can contact the touch-sensitive push switches 44. Under the action of wind, the fan blades rotate around the support rod, and the fan blades contact the touch-sensitive push switches 44 on the drive motor to turn on the drive motor. However, the drive motor stops working when there is no wind.

[0051] When a sandstorm arrives, it carries sand and dust into the centrifugal sand inlet 24. The sand and dust are separated by the stainless steel conical tube 28 and fall onto the circular tube shaft 5 before flowing into the sand collection cup 34 for storage. The high-precision weighing sensor 2 below records the weighing time and mass change in real time through the weighing transmitter, and transmits the data to a remote display screen for storage. Through the data remote antenna, the data is sent to the laboratory terminal computer to observe the sand and dust concentration change process in real time, so that the sand flux per unit area and per unit time can be calculated.
