The invention discloses a ceiling structure used for a snow accumulation prevention agricultural greenhouse. The ceiling structure comprises a ceiling board, wherein the upper end of the ceiling boardis fixedly connected with a plurality of supporting rods; in addition, the side wall of each supporting rod is independently rotatably connected with a magnetic board; an electromagnet is embedded into the upper end of the ceiling board and is arranged below a magnetic pole on one side of the magnetic board; the ceiling board is provided with a temperature difference power generation group formedby a plurality of temperature difference power generation sheets; and in addition, one end of the temperature difference power generation group is positioned above the ceiling board. Since the ceiling structure is provided with the temperature difference power generation group formed by the plurality of temperature difference power generation sheets, a huge temperature difference in and out of the greenhouse in winter forces the temperature difference power generation group to generate current, the current is changed into alternating current with certain frequency under a function of an inverter, a magnetic pole direction of the electromagnet can be intermittently changed so as to continuously attract and repel the magnetic boards, so that the magnetic boards rotate back and forth, and accumulated snow on the magnetic boards can be shaken down so as to prevent the accumulated snow from damaging the greenhouse.
本发明公开了一种防积雪农业大棚用棚顶结构，包括棚顶板，所述棚顶板的上端固定连接有多个支撑杆，且每个所述支撑杆的侧壁均转动连接有磁力板，所述棚顶板的上端嵌设有电磁铁，且所述电磁铁设置在磁力板的一侧磁极下方，所述棚顶板上设有多个温差发电片组成的温差发电组，且所述温差发电组的一端位于棚顶板的上方。本发明通过设置由多个温差发电片组成的温差发电组，利用冬季时大棚内外巨大的温差迫使温差发电组产生电流，并在逆变器的作用下变为一定频率的交流电，可间歇性的改变电磁铁的磁极方向，从而不断吸引、排斥磁力板，使得磁力板来回转动，可将磁力板上的积雪抖落，避免积雪对大棚造成损害。
