Description

Technical Field

[0001] This utility model relates to the field of particulate matter sampler technology, specifically a high-efficiency environmental PM2.5 particulate matter sampler. Background Technology

[0002] An atmospheric particulate matter sampler is an instrument or device used to collect atmospheric pollutants or polluted air. There are many types of atmospheric samplers. Based on the object being sampled, they can be divided into gas (including vapor) samplers and particulate matter samplers; based on the location of use, they can be divided into environmental samplers, indoor samplers (such as those used in factory workshops), and pollution source samplers (such as chimney samplers). In addition, there are special-purpose atmospheric samplers, such as those that simultaneously collect gases and particulate matter, which can collect sulfur dioxide and particulate matter, or hydrogen fluoride and particulate matter, etc., facilitating the study of the interaction between sulfur or fluorine in gaseous and solid substances. In a Chinese patent application (CN209784001U) titled "An Atmospheric Particulate Matter Sampler," a filter membrane of any type can be easily, quickly, and conveniently replaced by embedding it within a filter membrane holder. The filter membrane holder includes a holder cover, a holder carrier plate, and a filter membrane. A rectangular groove is provided on one side of the holder carrier plate, and the holder cover is embedded within the rectangle. The filter membrane is embedded between the holder cover and the holder carrier plate. When replacing the filter membrane, simply remove the holder cover from the holder carrier plate and replace it with a new filter membrane, which is convenient and quick. However, this device still has shortcomings. This air particulate matter sampler is cumbersome to carry and inconvenient to move during use, which reduces the flexibility of use and has certain limitations. At the same time, it lacks a protective storage mechanism, and in some special environments, it is impossible to protect the sampler when necessary. In order to solve the above problems, the inventor proposes a high-efficiency environmental PM2.5 particulate matter sampler. Utility Model Content

[0003] To address the problems of air particulate matter samplers being inconvenient to carry and move, reducing their flexibility during use, and lacking protective storage mechanisms that prevent them from being protected when necessary in certain special environments, the purpose of this utility model is to provide a high-efficiency environmental PM2.5 particulate matter sampler.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up a protective housing and cooperating with the protective cover, the limiting bottom block, and the limiting plate, this utility model solves the problem of lacking a protective storage mechanism, which makes it impossible to protect the sampler when necessary in some special environments. 2.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-4 As shown, this utility model provides a technical solution: a high-efficiency environmental PM2.5 particulate matter sampler, including a protective housing 1, a particle analyzer body 11 at the center of the protective housing 1, two sets of slots 33 symmetrically opened at the bottom of the protective housing 1 near the particle analyzer body 11, and limiting blocks 3 symmetrically provided at the bottom of the protective housing 1 near the slots 33. Limiting plates 31 are symmetrically fixedly connected to the tops of the two limiting blocks 3 and near the particle analyzer body 11, and casters 4 are fixedly connected to the bottom of the protective housing 1 near the corners.

[0018] A protective cover 12 is rotatably connected to the top of the protective box 1 near one side.

[0019] By adopting the above technical solution, a protective cover 12 is set on the top of the protective box 1 to facilitate the removal of the particle analyzer body 11 from the protective box 1.

[0020] A U-shaped plate 2 is fixedly connected to the side of the protective box 1, and a vertical shaft 21 is fixedly connected at the center between the inner walls of the U-shaped plate 2.

[0021] By adopting the above technical solution, a U-shaped plate 2 is set on the side of the protective box 1 to facilitate the installation of an anti-movement structure.

[0022] A support plate 22 is slidably connected to the outer ring of the vertical shaft 21, and a connecting shaft 25 is symmetrically fixed to the bottom end of the support plate 22 and near both sides.

[0023] By adopting the above technical solution, a liftable support plate 22 is set on the outer ring of the vertical shaft 21 in order to install two connecting shafts 25.

[0024] An auxiliary plate 26 is fixedly connected to the bottom end of the coupling 25.

[0025] The auxiliary plate 26 is installed at the bottom of the connecting shaft 25 by adopting the above technical solution in order to prevent the equipment from moving.

[0026] A lead screw 23 is rotatably connected between the inner walls of the U-shaped plate 2 and near the vertical axis 21, and the support plate 22 is rotatably connected to the lead screw 23 by a thread.

[0027] By adopting the above technical solution, after the lead screw 23 rotates, the threaded rotating support plate 22 can be raised and lowered.

[0028] A motor 24 is fixedly connected to the top of the U-shaped plate 2, and the output end of the motor 24 passes through the U-shaped plate 2 and is fixedly connected to the lead screw 23.

[0029] By adopting the above technical solution, the motor 24 is operated, thereby causing the fixedly connected lead screw 23 to rotate.

[0030] A rod 32 is slidably inserted into the bottom block 3 near one side, and the rod 32 is at the same level as the slot 33.

[0031] By adopting the above technical solution, inserting a rod 32 inside the limiting block 3 is to limit the limiting block 3 and prevent it from moving.

[0032] Working principle: When using this device, first place the particle analyzer body 11 in the protective box 1, then move the limiting bottom block 3 to contact the particle analyzer body 11 so that the limiting plate 31 can abut against the particle analyzer body 11 to prevent displacement. Then insert the rod 32 into the slot 33 through the limiting bottom block 3 to limit the limiting bottom block 3. Finally, reset the protective cover 12 and cover the protective box 1 to protect the particle analyzer body 11. By installing casters 4 at the bottom of the protective housing 1, the protective housing 1 can be moved, improving the overall flexibility of the equipment. When working, the motor 24 is started, causing the fixedly connected screw 23 to rotate, which causes the threaded rotating support plate 22 to descend under the action of the vertical shaft 21. This allows the two fixedly connected auxiliary plates 26 to contact the ground, increasing friction and preventing the equipment from moving during use.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
