The invention discloses an umbrella type
wind energy conversion device and an umbrella type
wind energy conversion system. The device comprises a rail
rope, and a lower control box, a lower baffle block and an upper baffle block which are fixedly connected to the rail
rope sequentially from top to bottom, wherein the lower control box is connected with a sliding
barrel through at least one umbrella control
rope; a plurality of work application umbrellas are connected between an umbrella edge and the sliding
barrel; the upper control box is in engagement transmission with a chain; when the lower control box reaches an operation
lower limit position relative to the ground, a first prompting
signal is transmitted to make the lower control box retract the umbrella control rope, so that the work application umbrellas are unfolded under the action of
wind power; and when the lower control box reaches an operation upper limit position relative to the ground, a second prompting
signal is transmitted to make the lower control box release the umbrella control rope, and the upper control box moves downwards along the chain to drive the tops of the work application umbrellas to move downwardsso as to fold the work application umbrellas. By the device and the
system, the work application umbrellas can be more stably unfolded and folded in the air, the phenomenon of twisting caused by redundant rope tools during unfolding and folding of the work application umbrellas can be effectively prevented, and high-power wind energy can be stably converted.
