Description

Technical Field

[0001] The utility model relates to the technical field of sampling, in particular to a dustproof structure of an exhaust gas sampler. Background Art

[0002] The exhaust gas sampling mechanism is also called the exhaust gas sampler. The exhaust gas sampler is used to sample and analyze the exhaust gas generated in the factory to prevent the exhaust gas emissions from exceeding the standard and polluting the air environment.

[0003] The existing exhaust gas samplers have the problem that the data transmission interface is easily contaminated by the external environment;

[0004] The reason for this problem is that the exhaust gas sampler is set up in an outdoor environment with exhaust gas emissions. The exhaust gas sampler collects air through the exhaust gas sampling end, and then the exhaust gas sample will enter the exhaust gas sampler, and then the data analysis device will perform data analysis. When the staff needs to collect exhaust gas sampling data, they need to insert the data collector into the data transmission interface and then analyze the collected data. The exhaust gas sampler is installed outdoors, and the data transmission interface is also exposed to the outside. The air quality at the location where the exhaust gas sampler is installed is poor, and there are more impurities in the air. At this time, the data transmission interface will be exposed to the outside for a long time and will be polluted to a certain extent, resulting in a large amount of dust accumulating inside the data transmission interface, affecting the use of later data transmission. Therefore, we propose a dust-proof structure for the exhaust gas sampler. Utility Model Content

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] The utility model embodiment discloses a dustproof structure of an exhaust gas sampler. Figure 1-4 As shown, it includes an exhaust gas sampler 1, which can refer to the gas sampler model dl6200. The outer surface of the exhaust gas sampler 1 is provided with a data transmission interface 101, and the outside of the data transmission interface 101 is provided with a dustproof mechanism. The dustproof mechanism includes an outer dustproof plate 2, which is movable on the outside of the data transmission interface 101. The outer dustproof plate 2 is used to dustproof the data transmission interface 101. The connecting frame 202 is arranged on the outside of the exhaust gas sampler 1, and the outer dustproof plate 2 is slidably connected to the outer surface of the connecting frame 202. The fixing part 203 is slidably arranged below the connecting frame 202, and the fixing part 203 is movably inserted into the inside of the outer dustproof plate 2. The fixing part 203 is used to fix the outer dustproof plate 2.

[0026] The exhaust gas sampler 1 collects air through the exhaust gas sampling end, and the exhaust gas is sucked into the exhaust gas sampler 1 through the sampling end. After the exhaust gas sample enters the exhaust gas sampler 1, the internal data analysis device of the exhaust gas sampler 1 will perform data analysis on the exhaust gas components. When the staff uses a data cable to connect the data collector data collection and the exhaust gas sampler 1, the internal sample data of the exhaust gas sampler 1 is transmitted to the data collector through operation, and the exhaust gas sampling work of the exhaust gas sampler 1 can be completed.

[0027] The two sides of the connecting frame 202 are fixedly connected with side panels 204, the inside of the side panels 204 is fixed with support rods 201, the outer surface of the outer dustproof plate 2 is fixedly connected with sliding blocks 207, the sliding blocks 207 are slidably connected to the outer surface of the support rods 201, and the sliding blocks 207 drive the auxiliary blocks 205 to pass through the gap between the connecting frame 202 and the side panels 204.

At this time, the fixing part 203 will slide on the outer surface of the limit block 208 until the fixing part 203 is movably inserted into the interior of the auxiliary block 205. In this way, the outer dustproof plate 2 is set at a position corresponding to the outer surface of the data transmission interface 101 to prevent the interior of the data transmission interface 101 from being contaminated. At the same time, the outer dustproof plate 2 is made of transparent material, and the internal situation can be observed at any time without affecting the normal use of the exhaust gas sampler 1.

[0030] By sliding the fixing part 203, the fixing part 203 will slide on the outer surface of the limit block 208 until the fixing part 203 leaves the inside of the auxiliary block 205, and then slide the outer dustproof plate 2 downward. At this time, the outer dustproof plate 2 will drive the sliding block 207 to slide on the outer surface of the support rod 201 until the outer dustproof plate 2 leaves the corresponding position of the outer surface of the data transmission interface 101. This is to facilitate the removal of the protection of the data transmission interface 101, and to facilitate the staff to insert the data collector into the inside of the data transmission interface 101, and the operation is simple.
