Description

Technical Field

[0002] During the in-warehouse maintenance of tobacco raw materials, it is one of the important maintenance measures to detect the temperature of tobacco piles. Traditional temperature detection is usually carried out by temperature measuring rods. A temperature measuring rod with a temperature sensor is placed for every 25 boxes of tobacco raw materials. According to the number of stacks of tobacco raw materials, usually 10 to 16 temperature measuring rods are placed for one pile. The temperature measuring rods are connected to the temperature collector outside the pile through cables to collect the temperature of the tobacco pile. However, the outside of the tobacco pile is usually covered with a sealing diaphragm as a whole. When the cables inside the tobacco pile are led out by the traditional method, the number of cables is large and the lines are messy. When the temperature of the tobacco pile is actually collected, it will bring great difficulty to the sealing work of the tobacco pile. In actual practice, the messy cables are often simply gathered together and then extended from the bottom of the sealing diaphragm as a whole. The space inside the sealing diaphragm will exchange air with the external environment through the gap at the cable at the bottom of the sealing diaphragm. It is inevitable that sealing leakage will occur, which will greatly affect the sealing effect of the tobacco pile and seriously affect the data collection and analysis of the in-warehouse maintenance quality of tobacco raw materials. In addition to the tobacco industry, other warehousing industries that involve connecting cables of various specifications in sealed and isolated places inside and outside, such as grain storage, also face similar problems.
