Description

Technical Field

[0001] The invention relates to the technical field of gas collectors, and in particular to a flow-guiding type gas sealed sampler. Background Art

[0002] Gas is one of the four basic states of matter. Gas can be composed of single atoms, single molecules composed of one element, compound molecules composed of multiple elements, etc. Gas mixtures can include multiple gaseous substances, such as air. The significant difference between gas and liquid and solid is that there is a large gap between gas particles. This gap makes it difficult for the human eye to detect colorless gas. Gas is a fluid like liquid: it can flow and deform. Unlike liquid, gas can be compressed. If there is no restriction (container or force field), gas can diffuse and its volume is not restricted or fixed. The atoms or molecules of gaseous substances can move freely with respect to each other. A gas collector is required when collecting gas.

[0003] When the existing device samples gas from the outside, it is impossible to prevent external impurities from entering the collector, and then the debris falling in the air when collecting gas from the outside will interfere with the gas collection work. Summary of the invention

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention provides a rotating component. When collecting gas outdoors, the natural wind from the outside drives the rotating rod to rotate on the rotating plate, so that the rotating rod drives the connecting frame to rotate. By providing a plurality of bent plates on the connecting frame, the contact area with the natural wind is increased, so that the natural wind drives the rotating rod and the connecting frame to rotate.

[0018] 2.

When the scraper is separated from the inner wall of the mesh, the scraper is reset and expanded by its own elasticity, so that the impurities attached to the scraper can be shaken off, thereby completing the self-cleaning work.

[0019] 3. The present invention arranges a sampling component. When collecting external gas, the rubber tube is placed in the inner cavity of the partition shell so that the top of the fixed block is against the inner wall of the circular groove through the through hole. At the same time, the extrusion plate is rotated, and the extrusion plate drives the fixed block to rotate and slide in the inner cavity of the circular groove through the rubber tube, so that the fixed block drives the first connecting block and the fixed plate to be limited and fixed. The extrusion rod is pressed and the extrusion plate is pushed at the same time. The extrusion rod drives the second stopper to disengage from the second connecting block. The extrusion plate drives the second connecting block to be squeezed toward the first connecting block through the connecting tube, so that the gas in the rubber tube is discharged through the leakage hole on the second connecting block, so that the rubber tube collects the gas.

[0020] 4. The present invention sets a buffer mechanism. When the rubber tube is reset to collect gas, the second connecting block drives the buffer rod to reset and move. Then, when the rubber tube is collecting samples, the bent rod drives the friction block and the buffer block to move in contact. The bent rod is made of elastic material, and the friction block is made of rubber material. Therefore, when the rubber tube is reset to collect gas, the collection speed can be slowed down, so that it is convenient to collect gases in different ranges when collecting gases.

By arranging a plurality of bent plates 33 on the connecting frame 32, the contact area with the natural wind is increased, so that the natural wind drives the rotating rod 31 and the connecting frame 32 to rotate. At the same time, when the connecting frame 32 rotates, the connecting rod 35 drives the grabbing rod 36 to rotate on the outer surface of the guide housing 21, so as to avoid leaves and other floating objects floating in the wind from entering the partition component 1 when collecting external gas. At the same time, by arranging the grabbing rod 36, the floating objects floating around the sampler following the natural wind can be grabbed to avoid interference with the gas collection work.

[0051] When the rubber tube 51 is reset, the first plug plate 54 is pulled to move in the rubber tube 51 by suction, so that the first plug plate 54 drives the first stopper 55 to separate from the air inlet 53, and then the gas enters the rubber tube 51 through the air inlet 53, thereby collecting the external gas;

[0052] The external gas enters the rubber tube 51 through the filter plate 61, and at the same time, it is prevented that some impurities in the gas enter the rubber tube 51. After the gas collection work is completed, by pushing the connecting ring 62, the connecting ring 62 drives the contact mechanism 65 to clean the filter plate 61 through the telescopic rod 63 and the first spring 64, so as to prevent the impurities in the mesh of the filter plate 61 from being blocked;

[0053] By pushing the connecting ring 62, the connecting ring 62 drives the contact rod 651 to move toward the filter plate 61, so that the contact block 653 pushes out the impurities at the mesh, thereby preventing the impurities from clogging the mesh. At the same time, the contact rod 651 continues to move, so that the scraper 655 is squeezed and contacted with the inner wall of the mesh. The scraper 655 is made of hard plastic. When the scraper 655 is scraped and contacted with the inner wall of the mesh, the scraper 655 can scrape off the impurities attached to the mesh. When the scraper 655 is squeezed by the inner wall of the mesh, the scraper 655 drives the connecting shaft 654 to rotate in the slide groove 652. When the scraper 655 is separated from the inner wall of the mesh, the scraper 655 is reset and unfolded by its own elasticity, so that the impurities attached to the scraper 655 can be shaken off, thereby completing the self-cleaning work.

[0054] When the rubber tube 51 is reset to collect gas, the second connecting block 512 drives the buffer rod 561 to reset and move, and then the rubber tube 51 causes the bending rod 562 to drive the friction block 563 to move in contact with the buffer block 16 when collecting samples. The bending rod 562 is made of elastic material, and the friction block 563 is made of rubber material, so that the collection speed can be slowed down when the rubber tube 51 is reset to collect gas, so that different ranges of gas can be collected.
