The invention relates to a solar power supply, infrared detection and sound and light alarm integrated bird repellent method. The solar power supply, infrared detection and sound and light alarm integrated bird repellent method is characterized by comprising arranging a bird repellent device on a transformer device, a tower of a power transmission line and a lightning rod respectively; charging a battery arranged in a casing through a solar energy light panel which is arranged on the motor and control device casing and enabling a motor and a control circuit to start to work so as to enable a rotating ball to rotate; performing infrared detection on the environment around the bird repellent device through an infrared detection lens which is arranged on the rotating ball and sending the harsh buzzing from the sound and light alarm and flashing the red light to give an alarm when birds are close to the bird repellent device until the birds leave; enabling the solar energy light panel to continue to charge the battery which is arranged in the motor and control device casing if no bird is close to the bird repellent device through judgment. According to the solar power supply, infrared detection and sound and light alarm integrated bird repellent method, the risk that the birds nest the transformer device and the tower of the power transmission line is greatly reduced through the infrared detection and sound and light alarm and accordingly the fault of the transformer device and the power transmission line due to bird strikes is avoided and the safe and stable operation of the device is ensured.
