Description

Technical Field

[0001] The utility model relates to the technical field of temperature and humidity detection of grain warehouses, in particular to a grain warehouse temperature and humidity anti-fumigation device. Background Art

[0002] A grain depot refers to a large warehouse or storehouse used to store grain. A grain depot is usually used to store major grain crops such as cereals, rice, and wheat to ensure their preservation and shelf life. A grain depot thermometer and hygrometer is an instrument used to measure the temperature and humidity inside a grain depot. It has the function of monitoring environmental conditions to ensure that grain is stored in a suitable environment. A thermometer and hygrometer can help control the humidity and temperature inside the grain depot to prevent the grain from getting damp, moldy, or spoiling. Grain depot fumigation is a commonly used grain storage prevention and control technology. Fumigation usually uses some suitable chemical agents, such as gaseous phosphides, such as aluminum phosphide or methyl bromide, etc., which control or kill pests, fungi, bacteria and other harmful organisms stored in the grain depot by releasing toxic gases. Fumigation can effectively inhibit pests and mildew and protect the storage quality of grain. When using fumigants, the fumigation gas may cause damage to the thermometer and humidity machine, thereby causing unnecessary losses.

[0003] For this purpose, the utility model patent with the publication number CN216559021U discloses a grain silo temperature and humidity fumigation prevention device, which relates to the field of grain depot temperature and humidity detection technology, including a protective shell, a sealing part is provided at one end of the protective shell, a sleeve is movably sleeved on the outer circumferential surface of the sealing part, an outer thread is provided on the outer circumferential surface of the end of the sealing part close to the protective shell, an inner thread is provided on the inner circumferential surface of the end of the sleeve close to the outer thread, a first sealing gasket is sleeved on the outer circumferential surface of the sealing part located between the outer thread and the protective shell, and a plurality of through holes are opened circumferentially on the sealing part. By arranging a sleeve structure at one end of the sealing part, the data collection in the grain depot will not be affected during the normal use of the device, and it can work efficiently and accurately. In the fumigation environment, the sensor can maintain an independent closed space relative to the outside world, so that it can avoid damage in the harsh environment, effectively extend the service life of the device, and reduce the impact on the normal detection of the grain depot.

[0004] However, this patent is not convenient to install. Grain warehouses are usually large. In order to ensure the accuracy of environmental information in the grain warehouse, thermometers and hygrometers need to be installed at multiple locations in the grain warehouse to accurately understand the environmental information in the grain warehouse. Moreover, this patent requires manpower to open and close, which wastes manpower and time. Utility Model Content
