[0026] A stabilizing frame 34 is fixedly installed on the second platform 4, and an early warning device 13 is fastened and installed inside the stabilizing frame 34. The early warning device 13 is provided with a sound wave emitting end, which is a sound wave playing structure, and the sound wave emitting end of the early warning device 13 is arranged on the top of the early warning device 13; a socket 35 electrically connected to the generator 12 is arranged on the side of the early warning device 13, and the early warning device 13 is electrically connected to the generator 12, and the generator 12 can supply current to the early warning device 13 when generating current; a frequency converter 36 for adjusting current is arranged on the circuit connecting the early warning device 13 and the generator 12, and the frequency converter 36 is fixedly installed on the second platform 4, and the frequency converter 36 can control the strength of the warning sound wave of the early warning device 13 according to the strength of the current.
[0027] The working principle of the present invention is: Before performing high-altitude power operations, power operators can transport the device to a high-altitude power operation platform. When power operators perform high-altitude power operations, the strong wind generated at high altitude can enter the wind guide cover 8, and after passing through the air outlet 27, it flows out through the through slot 29; during this period, the strong airflow generated at high altitude can cause the open ends of the two bell pieces 9 in each through slot 29 to collide with each other, thereby generating a sound warning. The stronger the strong airflow, the stronger the sound warning emitted by the bell piece 9, thereby directly reminding the power operators of the changes in the strong airflow; and the strong airflow generated at high altitude can drive the pneumatic wheel 7 to rotate, so that the driving rod 6 and the driven rod 5 are in transmission cooperation, and the first transmission plate 15 and the driven rod 5 are in transmission cooperation. With the cooperation of the second transmission plate 16, the turntable 3 is further rotated. Since the turntable 3 is provided with a bent groove 21, if the wind speed is small, the rotation of the turntable 3 is in a non-constant state, which makes it difficult for the generator 12 to output a continuous and reliable current, and thus the early warning device 13 cannot emit a continuous warning sound wave outward. If the wind speed is large, the rotation of the turntable 3 is continuous and long-lasting, so that the generator 12 can output a continuous and reliable current, and the early warning device 13 can emit a continuous warning sound wave outward, thereby providing timely warning to the power workers, so as to facilitate the power workers to evacuate the working platform in time.
[0028] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
