Aiming at the defects of the prior art: the grain condition temperature measuring system is mature and instant, and can monitor abnormal temperature points in a grain pile at any time; but the temporary grain pile has no grain condition temperature measuring system; however, the existing buried cable is not practical, and because the cable is very soft and the grains have fluidity, the monitoring is difficult; "this embodiment can be pioneering nature and set up the heat preservation cable in the grain heap fast.
Example nine: as a further modifiable scheme, or a parallel scheme or an optional independent scheme, the upper layer of heat insulation material 202 can prevent external high temperature from entering grains through grain interfaces; the double-layer heat insulation film covering ventilation structure 2 is suitable for the deformation capacity of the grain surface. The technical scheme of the invention has the following substantial technical effects and the realization process, namely the basic functions: the unfilled part in the horizontal warehouse and the grain are isolated by the aid of the upper-layer heat insulation material 202 creatively, so that heat sources are avoided, and the horizontal warehouse can adapt to the deformability of grain surfaces.
The walkway plate can realize air draft; the double-layer heat insulation film-covered ventilation structure 2 does not participate in air draft;
the double-layer heat insulation film covering ventilation structure 2 covers the grains with a layer of outer covering, so that the grains are heat insulated when the temperature is high;
the double-layer heat-insulation film-covering ventilation structure 2 is taken away when the temperature of the grain is high;
the film can also be fumigated, namely the film is relatively sealed integrally; hydrogen sulfide is prevented from entering the air in the grain bin; the absolute density of phosphine in the air space in the absolutely closed bin is not very small; greatly reduces the possibility of escaping the phosphine and realizes the possibility of killing insects in the grain gaps. Under this kind of mode, be fit for whole storehouse grain face and cover double-deck thermal-insulated tectorial membrane ventilation structure 2 and pavement board.
Creatively, the above effects exist independently, and the combination of the above results can be completed by a set of structure.
It should be noted that the plurality of schemes provided in this patent include their own basic schemes, which are independent of each other and are not restricted to each other, but they may be combined with each other without conflict, so as to achieve a plurality of effects.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined by the appended claims.
