The invention discloses an unmanned aerial vehicle water body fixed-point sampling device, and belongs to the technical field of water quality monitoring. The unmanned aerial vehicle water body fixed-point sampling device comprises an unmanned aerial vehicle body and a sampler, wherein the sampler comprises a sampling bottle and a bottle sleeve, the bottle sleeve is connected with the unmanned aerial vehicle body through a traction rope, a bottle cap pulled by a floating ball is arranged at the bottle opening of the sampling bottle, the floating ball is connected with the bottle cap through aconnecting wire, the length of the connecting wire is equal to the sampling depth of the sampling bottle, a reset mechanism is further installed on the bottle cap, and the bottle cap covers the bottleopening through the reset mechanism after the sampling bottle is filled. According to the invention, the floating ball pulls the bottle cap of the sampling bottle to be opened, so that the sampling bottle can start to contain water; the connecting wire of the floating ball is the sampling depth, so that fixed-point sampling is achieved; and the bottle cap is provided with the reset mechanism, andafter a water sample is taken, the reset mechanism can cover with the bottle cap, so that the water in the sampling bottle cannot be mixed with water in other areas, and the sampling accuracy is guaranteed.
本发明公开了一种无人机水体定点取样装置,属于水质监测技术领域,包括无人机本体和取样器,所述取样器包括取样瓶和瓶套,所述瓶套通过牵引绳与所述无人机本体连接,所述取样瓶的瓶口安装由浮球拉动的瓶盖,所述浮球和所述瓶盖之间通过连接线连接,所述连接线的长度为所述取样瓶的取样深度,所述瓶盖上还安装复位机构,通过所述复位机构使所述取样瓶装满后所述瓶盖盖住瓶口。通过浮球拉动取样瓶的瓶盖打开,使取样瓶可以开始盛水,浮球的连接线为取样的深度,从而实现定点取样,而且瓶盖上有复位机构,在取完水样后,复位机构可合上瓶盖,这样取样瓶内的水不会与其他区域的水质混杂,保证了取样的精确性。
