The invention discloses a bird repelling device, which aims to solve the problem that the current bird repelling device has a simple repelling action cycle, can quickly adapt to the birds, and causes the bird repelling effect to not last for a long time. The invention includes a threaded shaft, a top frame connected to the top of the threaded shaft, a threaded disk threaded on the threaded shaft, a driving part and a bird-repelling rod body, the top frame is rotatably connected to the threaded shaft, and the outer edge of the top frame is provided with a corresponding bird-repelling rod body. The positioning sleeve of the rod body, the bird-repelling rod body slides and is inserted in the positioning sleeve, and the other end is rotatably connected to the threaded disc. The free end of the bird-repelling rod body is provided with a bird-repelling part, and the driving part pushes the threaded disc up and down to drive the bird-repelling rod body Do bird repellent. The movement form is complex, although it is also a cycle, but the whole cycle changes in various ways. Keeping the vigilance of birds can effectively maintain the bird repelling effect. During the lifting process of the threaded disc, the movement mode of the bird repelling rod body is different.

The invention provides a wide-range bird repelling device which comprises an installation base, a fixing cylinder, a rotating shaft, at least one wind scoop and first reflectors. The installation base is suitable for being fixedly assembled with a power transmission pole in a matched mode. The fixing cylinder is fixedly arranged on the installation base and provided with an inner cavity with an upward opening. The rotating shaft is provided with a first section and a second section, wherein the first section is inserted in the inner cavity and rotationally connected with the fixing cylinder, and the second section stretches out of the inner cavity. The wind scoops are fixedly installed on the second section of the rotating shaft and can drive the rotating shaft to rotate under the action of wind force. The first reflectors are installed on the wind scoops and provided with spherical reflecting surfaces, and the spherical reflecting surfaces can reflect light rays irradiated on the spherical reflecting surfaces to repel birds. The reflection range of the first reflectors of the bird repelling device is wide, and the first reflectors can reflect light rays into the eyes of the birds once the birds appear nearby, so that the birds are startled and fly away quickly without staying or nesting on the power transmission pole, and thus the accidents such as short circuits and tripping of a line can be avoided.

The invention discloses an electric power transmission iron tower. The electric power transmission iron tower comprises a tower head and a tower body. Cross arms are arranged on the tower body. Insulators are arranged at the ends of the cross arms. A solar cell device is arranged on the tower head. The electric power transmission iron tower is characterized in that the electric power transmission iron tower further comprises a water supply device, a main bird repelling device and a plurality of bird repelling terminal devices, and the bird repelling terminal devices are arranged above the cross arms correspondingly. During bird repelling, on one hand, when an infrared detection sensor of any bird repelling terminal device detects that a bird exists nearby, a main controller controls an audible and visual alarm and an ultrasonic transmission module to work at the same time; and on the other hand, after a sub-controller of the bird repelling terminal device inducing that the bird exists nearby waits for the time TA, a water outlet pump and a water outlet valve are started for water spraying. According to the electric power transmission iron tower, the bird repelling effect is remarkably improved, the insulators are unlikely to be damaged by pecking of birds, the hovering time of the birds on the power transmission iron tower can be effectively shortened, the excretion amount is effectively reduced, the birds are made unlikely to nest on a power line, and thus the safety of electric power transmission is guaranteed.

The invention discloses a bird repelling method and a bird repelling device based on ultrasonic waves. The bird repelling method generates ultrasonic waves of various frequencies by a frequency-adjustable ultrasonic generating module inside a central processing module, and utilizes the difference between the bird-free duration t and the test duration T. The ratio characterizes the bird repelling effect of each frequency of ultrasonic waves, and the ultrasonic bird repelling effect test of each frequency is carried out, and the most suitable ultrasonic frequency for bird repelling is selected for bird repelling, so as to satisfy the bird repelling effect of different birds in various regions and periods. , to improve the efficiency of bird repelling. The bird repelling device includes a central processing module, an ultrasonic generating module, an ultrasonic speaker, a detection module, and a clock module; the ultrasonic generating module is an ultrasonic generating module with adjustable frequency, which emits ultrasonic waves of various frequencies to improve the bird repelling effect. .
