Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust sampler technology, and in particular to an anti-icing dust sampler for polar environments. Background Technology
[0002] The polar regions refer to the Earth's two poles, namely the North and South Poles. For the Arctic region, the local aerosols mainly consist of naturally occurring sea salt aerosols and ice particles. However, aerosols transported from Europe, Asia, and the Americas may include pollutants such as combustion smoke and secondary aerosols. These particulate matter, upon reaching the polar regions, not only cause environmental problems but also impact regional climates. For example, black carbon aerosols, primarily from combustion emissions, have a strong ability to absorb solar radiation. When black carbon exists in the polar atmosphere, it absorbs energy and heats the atmosphere. When black carbon falls onto the surface of polar ice and snow, it reduces surface reflectivity, increases surface heat absorption, accelerates ice and snow melting, and thus affects global climate.
[0003] The existing technical solutions mentioned above have the following drawbacks: When the existing dust sampler is used in snowy weather in polar environments, the air intake detection end lacks a protective structure against wind and snow. When collecting data, the detection port will be blocked by wind and snow, affecting the detection process. Utility Model Content
[0004] The purpose of this invention is to provide an anti-icing dust sampler for polar environments.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A polar environment anti-icing dust sampler includes a sampler body, an mounting base installed on the outside of the sampler body, a groove inside the mounting base, a scraper fixedly connected to the outside of the groove inside the mounting base, an installation plate inserted into the groove, a metal wire mesh fixedly connected to the inside of the installation plate, and a limit block and a handle fixedly connected to the outside of the installation plate.
[0007] By adopting the above technical solution, a wind and snow protection structure is added to the detection port of the sampler. A metal wire mesh is added inside the outer mounting base, and the metal wire mesh is installed inside the mounting plate. The mounting plate is then inserted into the mounting base to block wind and snow. At the same time, the surface of the metal wire mesh can be cleaned with a scraper to ensure the normal use of the structure.
[0008] Furthermore, a snow-proof louver is installed on the outer side of the mounting base, and an installation groove is reserved on the outer side of the snow-proof louver. A first clamping plate is fixedly connected to the outer side of the mounting base, and a second clamping plate is installed on the outer side of the first clamping plate. A bolt is inserted into the inside of the first clamping plate, and a nut is installed on the outer side of the bolt.
[0009] By adopting the above technical solution, the device can be installed on the outside of the sampler through the first and second clamps, and then connected by bolts and nuts to achieve quick installation, which can be installed and used at any time as needed.
[0010] Furthermore, one end of the mounting plate extends through the groove to the outside of the mounting base, the limiting block and the inner side of the mounting base are in contact with each other, and two scrapers are symmetrically arranged, with one end of the outer side of the scraper in contact with the surface of the metal wire mesh.
[0011] By adopting the above technical solution, when snow accumulates on the surface of the wire mesh, the wire mesh can be pulled up and down, and the surface of the wire mesh can be cleaned by a scraper.
[0012] Furthermore, the outer sides of the mounting groove and the mounting base are engaged, the outer side of the first clamping plate and the air inlet of the sampler body detection end are in contact with each other, the second clamping plate is engaged on the outer side of the air inlet of the sampler body detection end, the bolt passes through the first clamping plate and the second clamping plate and extends to the outer side of the second clamping plate, and the bolt and nut are threadedly connected.
[0013] By adopting the above technical solution, the structure is easy to install and disassemble, and can be installed and used at any time, which is convenient and quick.
[0014] In summary, the beneficial technical effects of this utility model are as follows:
[0015] The system employs a mounting base, snow-proof louvers, scraper, wire mesh, and clamps. The mounting base is connected to the sampler via two sets of clamps, bolts, and nuts, allowing air to pass through the mounting base before entering the sampler. Snow-proof louvers are added to the outside of the mounting base, and wire mesh is added inside to block wind and snow. In the event that wind and snow will eventually clog the wire mesh, it can be easily cleaned by pulling the wire mesh up and down and using the scraper. The louvers can then be removed for internal cleaning, resulting in convenient installation and use. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.
[0023] Reference Figure 1-5 A polar environment anti-icing dust sampler includes a sampler body 1, a mounting base 2 mounted on the outside of the sampler body 1, a groove 3 inside the mounting base 2, a scraper 4 fixedly connected to the outside of the groove 3 inside the mounting base 2, a mounting plate 5 inserted into the groove 3, a metal wire mesh 6 fixedly connected to the inside of the mounting plate 5, a limit block 7 and a handle 8 fixedly connected to the outside of the mounting plate 5, a snow-proof louver 9 mounted on the outside of the mounting base 2, a mounting groove 10 reserved on the outside of the snow-proof louver 9, a first clamping plate 11 fixedly connected to the outside of the mounting base 2, a second clamping plate 12 mounted on the outside of the first clamping plate 11, and a first clamping plate 12 fixedly connected to the outside of the first clamping plate 11. A bolt 13 is inserted into the sampler, and a nut 14 is installed on the outside of the bolt 13. A wind and snow protection structure is added to the detection port of the sampler. A metal wire mesh 6 is added inside the mounting base 2 on the outside. The metal wire mesh 6 is installed inside the mounting plate 5. The mounting plate 5 is inserted into the mounting base 2 to block wind and snow. At the same time, the surface of the metal wire mesh 6 can be cleaned by the scraper 4 to ensure the normal use of the structure. The device can be installed on the outside of the sampler through the first clamping plate 11 and the second clamping plate 12, and then connected by the bolt 13 and nut 14 to achieve quick installation. It can be installed and used at any time as needed.
[0024] like Figure 1-5 As shown, one end of the mounting plate 5 extends through the groove 3 to the outside of the mounting base 2. The limiting block 7 and the inner side of the mounting base 2 are in contact with each other. Two scrapers 4 are symmetrically arranged. One end of the outer side of the scraper 4 is in contact with the surface of the metal wire mesh 6. The mounting groove 10 and the outer side of the mounting base 2 are engaged. The first clamping plate 11 and the outer side of the air inlet at the detection end of the sampler body 1 are in contact with each other. The second clamping plate 12 is engaged on the outer side of the air inlet at the detection end of the sampler body 1. The bolt 13 extends through the first clamping plate 11 and the second clamping plate 12 to the outer side of the second clamping plate 12. The bolt 13 and the nut 14 are threadedly connected.
[0025] The implementation principle of this embodiment is as follows: First, the first clamping plate 11 on the outside of the mounting base 2 is brought into contact with the outside of the detection port of the sampler body 1. Then, the second clamping plate 12 is installed on the outside of the detection port. After that, the two clamping plates are clamped and fixed by bolts 13 and nuts 14. The wind and snow will be blocked by the snow-proof louvers 9 on the outside. At the same time, some wind and snow will enter the interior of the mounting base 2 and will be blocked by the wire mesh 6. Later, snow will accumulate on the surface of the wire mesh 6. At this time, the mounting plate 5 is pulled up and down, and the scraper 4 will clean the wire mesh 6 inside the mounting plate 5. At the same time, the snow-proof louvers 9 are removed to clean the accumulated snow inside the mounting base 2. The structure is simple and convenient to use.
