Problems solved by technology

In recent years, with the increase of the country's investment in the construction of grain depots, the grain storage environment of the grain depots has been significantly improved, coupled with the application of some new technologies, the rodents and pests in the grain depots have been effectively controlled, but preventing grain The mildew problem has not been solved well
However, the sensor can only detect temperature and humidity information. When it is windy, the temperature and humidity information will not change significantly in a short time, so the ventilation window will not be automatically adjusted for a short time. It will bring a lot of dust and other particles into the granary, affecting the quality of the grain in the granary

Abstract

The invention relates to the field of grain depot intelligent management and particularly discloses a grain depot intelligent ventilation system. The system comprises an external detection unit, a driving module, a main control server, a driving rod, a ventilation window door, and an air inlet part. The air inlet part comprises a ventilation pipe, a piston cylinder, and a lifting baffle. The portof the ventilation pipe port is provided with a window frame the top side of which is hinged to the top side of the ventilation window door. The piston cylinder comprises a cylinder body, an inflatingrod, a piston, and a check valve. One end of the cylinder body is closed and the other opposite end forms an opening. The piston is slidably connected with the cylinder body. One end of the inflatingrod is fixedly connected with one end, away from a closed end of the cylinder body, of the piston. One end, away from the piston, of the inflating rod is fixedly connected with one end, away from thehinged part, of the ventilation window door. The check valve is arranged at the closed end of the cylinder body. The closed end of the cylinder body is fixedly connected with one end of the driving rod, and the other end of the driving rod is fixedly connected with the bottom side of the window frame. The lifting baffle comprises an inner baffle and an outer baffle. According to the technical scheme of the invention, the opening degree of the ventilation window can be automatically adjusted according to the wind strength.

Description

technical field [0001] The invention relates to the field of intelligent management of grain depots, in particular to an intelligent ventilation system for grain depots. Background technique [0002] As an important strategic material of the country, grain reserves have played an important role in maintaining the stability of the grain market, protecting the interests of farmers, and ensuring national security. In recent years, with the increase of the country's investment in the construction of grain depots, the grain storage environment of the grain depots has been significantly improved, coupled with the application of some new technologies, the rodents and pests in the grain depots have been effectively controlled, but preventing grain The mildew problem has not been well resolved. After long-term exploration and practice, it has been proved that as long as the temperature and humidity in the granary are effectively controlled, the grain in the granary can be well prese...
