The invention discloses a self-snow-removing type greenhouse structure which comprises a base, a supporting rod is welded to the upper end of the base, a greenhouse top plate is arranged at the upperend of the supporting rod, a first electromagnet is arranged at the upper end of the greenhouse top plate, and second electromagnets are arranged on the two side walls of the greenhouse top plate. Theopposite magnetic poles of the first electromagnet and the second electromagnet are opposite when the first electromagnet and the second electromagnet are powered on, a plurality of ejector rods arefixedly connected to the greenhouse top plate, the side walls of the ejector rods are rotationally connected with snow baffles through spring shafts, and the snow baffles are composed of silicon steelsheets. Current is generated through the thermoelectric power generation set and is converted into alternating current with the direction and the size changing continuously under the action of the inverter, so that the magnetic field between the first electromagnet and the second electromagnet changes continuously accordingly, the stress direction of each snow baffle changes continuously, and thesnow baffles can shake back and forth along the rotating axes of the snow baffles; therefore, accumulated snow covering the snow blocking plate can be shaken off, and damage of the accumulated snow to the greenhouse is avoided.
本发明公开了一种自除雪式温室大棚结构，包括基座，所述基座的上端焊接有支撑杆，所述支撑杆的上端设有棚顶板，所述棚顶板的上端设有第一电磁铁，所述棚顶板的两侧壁均设有第二电磁铁，且所述第一电磁铁与第二电磁铁在通电时异性磁极相对，所述棚顶板上固定连接有多个顶杆，所述顶杆的侧壁通过弹簧轴转动连接有挡雪板，且所述挡雪板由硅钢片构成。本发明通过温差发电组产生电流，并在逆变器的作用下转变为方向及大小不断改变的交流电，从而使第一电磁铁与第二电磁铁之间的磁场随之不断变化，以使得各挡雪板受力方向不断改变，可沿其转动轴心来回抖动，从而可将挡雪板上覆盖的积雪抖落下来，避免积雪对大棚造成损坏。
