Description

Technical Field

[0001] The utility model relates to the technical field of atmospheric samplers, in particular to a wind and sand proof atmospheric sampler. Background Art

[0002] Atmospheric environment monitoring is the process of measuring the concentration of pollutants in the atmospheric environment, observing and analyzing their changes and their impact on the environment. Atmospheric pollution monitoring is the process of measuring the types and concentrations of pollutants in the atmosphere, and observing their temporal and spatial distribution and changing patterns.

[0003] An atmospheric sampler is an instrument or device for collecting atmospheric pollutants or polluted atmosphere. There are many types of atmospheric samplers. According to the collection object, they can be divided into gas samplers and particulate samplers. According to the place of use, they can be divided into environmental samplers, indoor samplers and pollution source samplers. In addition, there are special-purpose atmospheric samplers, such as samplers that collect gas and particulate matter at the same time, which can collect sulfur dioxide and particulate matter, or hydrogen fluoride and particulate matter in the atmosphere, etc., which is convenient for studying the relationship between sulfur or fluorine in gaseous and solid substances. There are also samplers for collecting bacteria in the air.

[0004] However, when the existing atmospheric samplers are used in a windy and sandy environment, the device cannot resist the wind and sand, causing sand, dust and other particles in the air to enter the sampling tube of the device through the exhaust pipe. When sand, dust and other particles accumulate inside the sampling tube, the detection data is easily affected.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the above background technology, the existing devices in the prior art are unable to resist wind and sand, resulting in sand, dust and other particles contained in the air entering the sampling tube of the device, which can easily affect the detection data.

[0007] The utility model discloses an anti-wind and sand atmospheric sampler, comprising a V-shaped tube, a suction head is fixedly installed on the right end of the V-shaped tube, an annular groove is opened on the left end of the V-shaped tube, a filter is fixedly installed on the inner wall of the annular groove, a flange connector is fixedly installed on the left end of the V-shaped tube, a pipeline is fixedly installed on the inner wall of the flange connector, and an air pump is fixedly installed on the left end of the pipeline.

[0008] Furthermore, a sampler body is fixedly mounted on the outer surface of the vacuum pump, a connecting pipe is fixedly connected to the bottom surface of the V-shaped tube, and a gear ring is rotatably connected to the outer surface of the connecting pipe.

[0009] Furthermore, a disc is fixedly connected to the outer surface of the connecting pipe, and a protective shell is fixedly connected to the outer surface of the disc.

[0010] Furthermore, the inner wall of the protective shell is rotatably connected with connecting pins arranged at equal distances, and the bottom end of each connecting pin is fixedly connected with a gear.

[0011] Furthermore, the outer surface of each gear is meshed with the inner wall of the gear ring, and the inner wall of each gear is threadedly connected with a threaded rod.

[0013] Furthermore, a collecting cylinder is fixedly connected to the upper surface of the bottom plate, and an outer surface of the collecting cylinder is in sliding contact with an inner wall of the connecting pipe.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model provides a V-shaped tube, an air suction head, a filter, a flange connector, a pipeline, an air pump and other components. The V-shaped tube is installed, and the air suction head is installed at the right end of the V-shaped tube. An annular groove is formed and the filter is installed inside the annular groove to limit the filter. The pipeline is connected to the V-shaped tube through the flange connector. When the air pump is working, air is sucked through the air suction head. When the gas passes through the inside of the V-shaped tube, it is filtered through the filter to isolate sand and dust inside the V-shaped tube and finally fall at the lowest point of the V-shaped tube. The device can prevent sand and dust from entering the air pump and the inside of the device, thereby resisting wind and sand.

[0016] 2. The utility model sets connecting pins, gears, gear rings, threaded rods, collecting barrels and other components, drives the collecting barrel to move by moving the bottom plate, drives the threaded rod through the disc and is placed corresponding to the corresponding gear by the collecting barrel, and rotates the gear ring to make the corresponding gear rotate, thereby realizing the synchronous rotation effect of multiple gears. The gear is limited by the rotation of the connecting pin and the protective shell, and the collection barrel is connected to the connecting pipe through the connection of the gear and the threaded rod, thereby realizing the effect of the device being able to isolate the filter element from the sand and dust inside the V-tube for collection. Conversely, the collection barrel can be disassembled by rotating the gear ring in the opposite direction, so that the collected sand and dust can be cleaned up. BRIEF DESCRIPTION OF THE DRAWINGS
