The invention discloses a sand prevention device for an unmanned aerial vehicle, and relates to the technical field of unmanned aerial vehicle accessories, the sand prevention device comprises a shell, the shell comprises an air inlet panel, an air outlet panel parallel to the air inlet panel and an air guide ring plate, a separation bin is arranged between the air inlet panel and the air outlet panel, the air inlet panel is arranged above the air outlet panel, and the air guide ring plate is arranged at the bottom of the air outlet panel; the two sides of the air inlet panel and the two sides of the air outlet panel are each provided with a plurality of sand outlet pipes communicating with the separation bin. A plurality of first air holes are formed in the air inlet panel, and a plurality of second air holes are formed in the air outlet panel; a sand-dust separation assembly and a sand outlet assembly are arranged on the shell; when air enters the shell from the first air hole, sand and dust from the first air hole are guided into the separation bin through the sand and dust separation assembly, pure air is guided into the air guide ring plate, the pure air enters the air inlet of the engine through the air guide ring plate, and the sand and dust entering the separation bin are discharged through the sand discharging assembly; therefore, the purity of the air entering the air inlet of the engine is high enough.
本发明公开了无人机用防砂装置,涉及到无人机配件技术领域,包括:壳体包括进气面板、与进气面板平行设置的出气面板以及导气环板,进气面板与出气面板之间为分离仓,进气面板设置于出气面板的上方,导气环板设置于出气面板底部;进气面板和出气面板的两侧均设置有多个与分离仓贯通的出砂管;进气面板上设置有多个第一气孔,出气面板设置有多个第二气孔;壳体上设置有砂尘分离组件和出砂组件;本发明当空气从第一气孔进入壳体,通过砂尘分离组件将来自第一气孔的砂尘导入分离仓以及将纯净空气导入导气环板中,纯净的空气经过导气环板进入发动机进气口,而进入分离仓内的砂尘经过出砂组件排出,从而确保进入发动机进气口的空气纯净度足够高。
