Technical Field
[0001] This utility model relates to the field of atmospheric dustfall technology, and in particular to an atmospheric dustfall sample processing device. Background Technology
[0002] Atmospheric dustfall refers to particulate matter that settles naturally in a dust collection tank under atmospheric conditions. These particles originate from various sources and have morphological, chemical, physical, and thermodynamic characteristics. In this case, it is necessary to place a dust collection tank outdoors to collect the falling dust particles.
[0003] When collecting atmospheric dust, it is necessary to take into account the different wind forces and directions, and adjust the angle of the dust collection cylinder synchronously according to the wind direction angle to ensure that the dust in the atmosphere can enter the dust collection cylinder and will not affect the subsequent measurement accuracy.
[0004] However, when adjusting the angle of the dust collection cylinder, it is necessary to use an anemometer to measure the direction and angle of the wind, and then adjust the opening position of the dust collection cylinder according to the angle of the wind to ensure that the opening of the dust collection cylinder is opposite to the wind direction. This adjustment is troublesome and inconvenient. Therefore, this application proposes an atmospheric dust sample processing device. Utility Model Content

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0025] Example 1
[0026] like Figures 1-8 As shown, the present invention proposes an atmospheric dust sample processing device, including a dust collection cylinder 1, a threaded pipe 2 fixedly connected to the bottom of the dust collection cylinder 1, a sleeve 3 threadedly connected inside the threaded pipe 2, a telescopic groove 8 opened inside the sleeve 3, a rotating rod 5 rotatably connected inside the telescopic groove 8, a wind baffle 7 fixedly connected outside the rotating rod 5, two wind baffles 7 are arranged symmetrically, the wind baffles 7 are slidably connected inside the sleeve 3, the wind baffles 7 are made of flexible steel, and a rotating assembly is provided outside the dust collection cylinder 1.
[0027] The rotating assembly includes a connecting shell 17. There are two connecting shells 17 that are symmetrically fixed to the outside of the dust collection cylinder 1. A rubber pad 18 is embedded inside the connecting shell 17. The rubber pad 18 abuts against the outside of the dust collection cylinder 1. A slide rod 23 is fixedly connected to the side of the rubber pad 18 away from the dust collection cylinder 1. A positioning tube 20 is rotatably connected to the outside of the slide rod 23 away from the slide rod 23.
[0028] A frame 21 is fixedly connected to the end of the positioning tube 20 away from the slide bar 23. The frame 21 is U-shaped. A clamping spring 19 is provided on the outside of the positioning tube 20 and the slide bar 23. The two ends of the clamping spring 19 are rotatably connected to the rubber pad 18 and the opposite side of the frame 21.
[0029] The frame 21 is fixedly connected to a handle 22, and there are two sets of handles 22 arranged symmetrically.
[0030] In this embodiment, during use, the operator can hold the handle 22, place the frame 21 in a position facing the wind, select a dust collection cylinder 1 of appropriate size and put it into the frame 21. When the dust collection cylinder 1 is put in, first pull one side of the rubber pad 18, so that the rubber pad 18 drives the slide rod 23 to slide into the positioning tube 20. At the same time, the rubber pad 18 and the frame 21 will compress the clamping spring 19 as they approach each other. Then, first insert the other side of the rubber pad 18 into the connecting shell 17, and then release the pressed rubber pad 18. The clamping spring 19 will push the rubber pad 18 into the connecting shell 17, thereby installing the dust collection cylinder 1 between the two rubber pads 18. Then, the sleeve 3 is rotated along the threaded tube 2 and installed below the dust collection cylinder 1.
[0031] After the sleeve 3 is installed stably, the wind baffle 7 is pulled out from the inside of the telescopic groove 8 along the outside of the sleeve 3. The wind baffle 7 will drive the rotating rod 5 to rotate, thereby releasing the wind baffle 7 from the outside of the rotating rod 5. When the wind baffle 7 is fully pulled out, it will achieve a nearly flat structure. When the wind blows, the wind force is applied to the surface of the wind baffle 7. At this time, the wind baffle 7 will exert force diagonally upward due to the wind force. Excess wind force will leak out from the gap between the bottom of the wind baffle 7 and the frame 21, and the dust collection cylinder 1 will be moved along with it. The connecting shell 17 and the rubber pad 18 restrict and ensure that the dust collection cylinder 1 will not move backward. At this time, the dust collection cylinder 1 will rely on the rubber pad 18 to drive the sliding rod 23 to rotate inside the positioning tube 20. In this way, the opening of the dust collection cylinder 1 will face the direction from which the wind blows, thereby collecting dust.
[0032] It should be noted that this device relies on the wind baffle 7 to change position driven by wind force, so that the wind baffle 7 drives the sleeve 3 and the dust collection cylinder 1 to move. When the dust collection cylinder 1 is under force, it will rotate inside the positioning tube 20 by the slide rod 23, ensuring that the opening of the dust collection cylinder 1 faces the direction from which the wind blows. This avoids the problem of having to measure the wind direction and adjust the position of the dust collection cylinder 1 multiple times in the past, and improves the convenience of adjusting the angle of the dust collection cylinder 1.
[0033] Example 2
[0034] like Figures 2-8As shown, based on embodiment 1, a rotating knob 9 is fixedly connected to one end of the rotating rod 5. The rotating knob 9 is located outside the sleeve 3. A positioning rod 10 is fitted outside the rotating knob 9. The positioning rod 10 is slidably connected inside the sleeve 3 and the telescopic groove 8. A pushing component is provided at the end of the positioning rod 10 away from the rotating knob 9.
[0035] The pushing assembly includes a pushing plate 13, which is fixedly connected to the end of the positioning rod 10 away from the rotating knob 9. A positioning spring 14 is fixedly connected to the side of the pushing plate 13 away from the positioning rod 10. A limiting plate 16 is fixedly connected to the end of the positioning spring 14 away from the pushing plate 13. The limiting plate 16 is fixedly connected inside the telescopic groove 8. A sliding rod 15 is fixedly connected to the side of the pushing plate 13 near the positioning spring 14. The sliding rod 15 is slidably connected inside the limiting plate 16.
[0036] A limiting piece 11 is fixedly connected to the outer side of the positioning rod 10 near the bottom of the telescopic groove 8. A positioning frame 12 is slidably connected to the outer side of the positioning rod 10 near the push plate 13. There are two positioning frames 12, which are fixedly connected to the bottom of the inner side of the telescopic groove 8 in an "L" shape.
[0037] A spring-loaded groove 6 is provided inside the sleeve 3 at a position away from the rotating knob 9. One end of the rotating rod 5 is rotatably connected inside the spring-loaded groove 6, and a worm spring 4 is fixedly connected to one end of the rotating rod 5. The end of the worm spring 4 away from the rotating rod 5 is fixedly connected inside the spring-loaded groove 6.
[0038] In this embodiment, when the wind deflector 7 is pulled out, its metal material will curl inside the telescopic groove 8 and generate a contraction force. At this time, the positioning spring 14 will push the push plate 13, causing the push plate 13 to drive the positioning rod 10 to slide out from inside the telescopic groove 8 along the sleeve 3. When the positioning rod 10 slides out, it will be stuck outside the rotating knob 9. This ensures that the rotating rod 5 will not rotate and that the wind deflector 7 will not retract into the telescopic groove 8. When the positioning rod 10 extends, the limiting piece 11 can limit the extension length of the positioning rod 10 to prevent the positioning rod 10 from slipping out of the telescopic groove 8 and the sleeve 3.
[0039] When the wind deflector 7 needs to be retracted into the telescopic groove 8, a shim can be used to push the positioning rod 10 in. The positioning rod 10 will retract inward, causing the push plate 13 to squeeze the positioning spring 14. When the positioning spring 14 retracts, the sliding rod 15 slides inside the limiting plate 16, ensuring that the positioning spring 14 will not bend during extension and retraction. The positioning frame 12 provides auxiliary support for the extension and retraction of the positioning rod 10. When the positioning rod 10 is disengaged from the outside of the rotating knob 9, the worm spring 4 will apply rotational force to the rotating rod 5 inside the spring return groove 6, thereby causing the rotating rod 5 to drive the wind deflector 7 to retract into the telescopic groove 8.
[0040] It should also be noted that the device uses the spring force released by the worm spring 4 inside the spring groove 6 to drive the rotating rod 5 to rotate, thereby controlling the retraction of the wind deflector 7. The positioning rod 10 is fitted outside the rotating knob 9 to restrict the rotation of the rotating rod 5, preventing the wind deflector 7 from retracting into the telescopic groove 8, thus increasing the control effect of the wind deflector 7's extension and retraction.
[0041] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
