Description

Technical Field

[0001] The present invention relates to the technical field of carbon dioxide detection, and more specifically, to a device and method for detecting carbon dioxide gas. Background Art

[0002] Carbon dioxide is a carbon oxide with the chemical formula CO2 and a chemical formula weight of 44.0095. It is a colorless and odorless or colorless and odorless gas at room temperature and pressure, and its aqueous solution has a slightly sour taste. It is also a common greenhouse gas and a component of air. Currently, carbon dioxide is usually canned for subsequent transportation and use, but in order to ensure the quality of carbon dioxide, detection equipment is usually required for detection.

[0003] A basic search found that a Chinese patent with patent number CN220626325U discloses a carbon dioxide detector, including a detector body, a display and function buttons are arranged on the front side of one side of the detector body, a detection probe is connected to the top of the detector body through a connecting plate and a connecting pipe, and an auxiliary component is arranged on the outer side of the detection probe; a protective component is arranged on the outer side of the detector body, and a plurality of grip grooves are arranged on both sides of the protective component, so that the detector body can be protected to ensure that the detector body provides an instantaneous buffering effect when it falls or collides with other objects, avoids hard collision between the detector body and the object, reduces the impact force on the detector body, and provides a buffering protection for the detector body.

[0004] Regarding the above-mentioned related technologies, in the actual operation process, although the above-mentioned carbon dioxide detection instrument can detect carbon dioxide, the instrument has certain limitations due to the limited operation mode. In the existing detection environment, it is usually necessary to face a large number of test samples in batches, and each batch of test samples is of a uniform quantity. However, it is not convenient for the staff to test a large number of samples in multiple batches, resulting in slow and inefficient detection. At the same time, carbon dioxide is often used to isolate air during welding to prevent the weld from being oxidized. Under normal circumstances, the purity can reach about 95%, but in the case of too many samples with a purity lower than 95% in a batch detection, no warning can be issued, which makes it inconvenient to find the specific cause in time. For this reason, a detection device and method for carbon dioxide gas are proposed. Summary of the invention

When the collection tank 271 moves to the bottom of the test unloading assembly 160, the first cylinder 162 drives the carbon dioxide detector 163 and the sleeve 164 to descend. During the descent, the sleeve 164 will be sleeved on the outer surface of the gas outlet pipe 272 and enter the interior of the sealing groove 279 to press the sleeve 277.
