The invention provides an umbrella-shaped occupying-type acousto-optic hybrid bird repelling device. A shaft sleeve is connected at the bottom end of a supporting rod in a sleeving way, and the supporting rod is rotatably connected with the shaft sleeve; the lower end of the shaft sleeve is connected with a fixing mechanism; the supporting rod is provided with a control box and a circumferential ultrasonic transmitter; the control box is arranged in the covering range of a baffle; a single chip microcomputer is in communication connection with an upper computer through a communication module to obtain a control instruction and transmit communication data; the single chip microcomputer is connected with the circumferential ultrasonic transmitter through an ultrasonic control circuit and controls the ultrasonic transmitter to operate and emit bird repelling sound when the time information of a timing module reaches a preset time point. Electrical bird repelling elements are arranged below the baffle, so that erosion by rain and snow can be avoided, each electrical bird repelling element can be protected, the use time is prolonged, and the operation effect is guaranteed. A plurality of bird repelling modes such as sound and strong light are also set for the device, the bird repelling effect is improved, photovoltaic power generation can also be realized, and the endurance of the device is improved.
