UAV (unmanned aerial vehicle) heat-dissipating device

Abstract

The invention discloses an UAV (unmanned aerial vehicle) heat-dissipating device, comprising a first installation ring and an UAV bottom plate, wherein an external side of the bottom end of the firstinstallation ring is fixedly connected with a second installation ring; an internal side of the first installation ring is fixedly connected with a connecting rod; the first installation ring is connected with a driving structure through the connecting rod; the driving structure is composed of a driving cover and a driving seat; the driving seat is fixedly connected with the connecting rod; a driving groove is formed in the center of the driving cover and the driving seat; a fan-shaped groove is formed in the top of the driving seat; the fan-shaped groove is internally provided with blades; aprotrusion block is fixedly arranged on the external side of the top end of the first installation ring; a telescopic groove is formed in the protrusion block; a transmission plate is arranged in thetelescopic groove; a fixed column is fixedly arranged on one end of the transmission plate; the other end of the transmission plate is fixedly provided with a pressing column. According to the UAV (unmanned aerial vehicle) heat-dissipating device disclosed by the invention. When one blade is damaged, blade can be replaced independently, avoiding replacement of all the blades.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a cooling device for drones. Background technique [0002] UAV, because of its high efficiency, low cost, good effect and many other advantages, gradually plays an important role in the fields of urban management, emergency rescue and disaster relief, meteorological monitoring, agricultural production and so on. During the flight of UAV, it will generate heat , heat dissipation is required, but when the UAV is flying in the air, it will be greatly affected by the airflow. Considering the stability of the flight of the UAV, the cooling device is generally installed at the bottom of the UAV to reduce the heat dissipation time of the cooling fan. The effect of the resulting airflow on the drone. [0003] The inventor of the present application found that the heat dissipation fan blades of the existing drones may be accidentally damaged during flight, and when the fan blades are dama...
