The rear end face of the rotating shaft 205 is rotatably connected to the rear side of the inner wall of the installation box 210, and the positions of the two knocking balls 208 are matched with the positions of the sound plate 206. The outer surface of the blade 203 is provided with a glitter coating 211, and the top and bottom of the installation box 210 are provided with sound grooves 204.

[0025] The effect achieved by the entire embodiment 1 is that, through the cooperation of the mounting seat 201 and the support rod 202, the mounting box 210 is fixed on the crossarm body 1, and then the flash coating 211 on the blade 203 can flash under the sunlight, provide visual stimulation to the birds, and drive the birds away. At the same time, under the action of the blade 203, the wind force can be captured to rotate, driving the rotating shaft 205 to rotate, so that the knocking ball 208 periodically knocks the sound plate 206 to generate sound and vibration. The two springs 209 are set to buffer the knocking force and protect the sound plate 206 from damage. Then, through the sound grooves 204 at the top and bottom of the mounting box 210, the sound generated is diffused and propagated, and the birds on the crossarm body 1 are driven away, so as to prevent birds from perching on the crossarm body 1 and ensure the safety of power transmission.

[0027] The effect achieved by the entire embodiment 2 is that, through the setting of the guide vane 207, it can be used to guide the wind direction, so that the blade 203 can capture the wind more effectively. At the same time, with the cooperation of the first reinforcement rib 6 and the second reinforcement rib 7, the load-bearing capacity and wind pressure resistance of the cross-arm body 1 are improved, ensuring its safe operation under severe weather conditions, and the suspension line is conveniently carried out through the first suspension 3 and the second suspension 5.

At the same time, under the action of the blade 203, it can capture the wind force to rotate, driving the rotating shaft 205 to rotate, so that the knocking ball 208 periodically knocks the sound plate 206, generating sound and vibration. The two springs 209 are set to buffer the knocking force and protect the sound. The plate 206 is not damaged, and then the sound is diffused and propagated through the sound grooves 204 at the top and bottom of the installation box 210, and the birds on the cross-arm body 1 are driven away. The setting of the guide vane 207 can be used to guide the wind direction, so that the blade 203 can capture the wind more effectively, avoiding birds from perching on the cross-arm body 1, and ensuring the safety of power transmission. At the same time, with the cooperation of the first reinforcement rib 6 and the second reinforcement rib 7, the load-bearing capacity and wind pressure resistance of the cross-arm body 1 are improved, ensuring its safe operation under adverse weather conditions.
