Description

Technical Field

[0001] The utility model relates to the field of electrical cabinets, in particular to an electrical cabinet for gas concentration detection. Background Art

[0002] The electrical cabinet is a cabinet made of steel to protect the normal operation of components. The materials used to make electrical cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are softer than hot-rolled steel plates and are more suitable for the production of electrical cabinets. Electrical cabinets are widely used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc. The electrical control cabinet is a supporting device that assists people in controlling the granary. It integrates the data and production data of each sensor into the central database to realize the real-time monitoring of the granary by time, space, region, and human factors. The granary monitoring system mainly completes the collection, storage, and transmission of data to the monitoring center for parameters such as grain temperature, humidity, gas concentration, pests, and moisture, as well as the execution of the instructions of the monitoring center. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of electrical control cabinets.

[0003] When the carbon dioxide meter in the electrical cabinet is performing carbon dioxide detection, the air pipe to be detected needs to be connected. However, the air pipe to be detected comes from various directions, and the external interface of the internal pipeline connected to the carbon dioxide meter is usually in a relatively fixed position. The air pipe to be detected needs to be bent and twisted before it can be connected to the external interface of the internal pipeline. During this process, the air pipe to be detected may become tangled or deflated due to bending or entanglement, and then cannot take in air and affect the overall detection result, which is very inconvenient.
