Description

Granary ventilation heat preservation window Technical Field The utility model relates to the technical field of granaries, in particular to a ventilation and heat preservation window for a granary. Background The large-scale granary is internally provided with a ventilation heat preservation window, and the ventilation heat preservation window is opened and closed in different seasons, so that ventilation or heat preservation is realized for the granary. The prior granary ventilation heat preservation window comprises a window frame 10, wherein an anti-bird net is fixedly arranged in the window frame 10, and a heat preservation door leaf 20 is hinged on the inner side of the window frame 10. Because the gap of the bird preventing net is larger, small insects easily enter the granary when the window is opened and ventilated. In the prior art, china patent document CN221503168U discloses 2024.08.09, namely a grain bin insect prevention heat preservation inner window with good air tightness, which comprises a bottom plate, wherein the top surface of one end of the bottom plate is fixedly connected with two first hinge plates, the two first hinge plates are rotationally connected with the top surface of the end part of a middle plate fixedly connected with the two first hinge plates, the top surface of the middle plate is fixedly connected with two second hinge plates near one end of the first hinge plate, the two second hinge plates are rotationally connected with the top surface of one end of a top cover plate. The insect-proof ventilating device has the advantages that the mesh holes of the fine net structure in the middle plate are small and are used for blocking insects and eggs, the mesh holes of the coarse net structure are large and are used for blocking birds and beasts, the ventilating device cannot cause excessive influence on ventilation, only the top cover plate is opened during ventilation, insect prevention and ventilation can be realized, the middle plate and the top cover plate can be opened together during an insect-free season, the fine net structure does not cover a ventilation position any more, the ventilating effect is better, a ventilating mode can be selected according to actual conditions, negative influence of the fine net structure on ventilation during the insect-free season is avoided, and the insect-proof ventilating device has the advantages that the mesh holes of the fine net structure in the middle plate are small, mosquitoes, dust and the like are particularly easy to attach to the fine net structure, and the fine net structure is fixed on the middle plate, so that attachments such as mosquitoes, dust and the like on the fine net structure cannot be cleaned conveniently.
