Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The embodiment of the present application provides a transformer noise signal extraction device and an installation method thereof, thereby solving the problem in the traditional technology that if the extraction device is directly installed on the supporting bracket of the transformer, on the one hand, the microphone assembly is not protected and is easily damaged by collision; on the other hand, the microphone assembly cannot face the center position of the side of the transformer, resulting in unstable reception of some abnormal noises at the farther side.

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] The embodiment of the present invention discloses a transformer noise signal extraction device.

[0041] The transformer noise signal extraction device, through the design of the clamping unit 3, makes the installation base 1 convenient and fast to limit the target height on the transformer supporting pole 2, thereby providing preliminary positioning for the entire device. After the preliminary positioning, the support fixing frame 4 and the bearing seat 41 are used to provide support for the microphone mounting seat 5 and the microphone body 81. With the design of the adjustment unit 6, the horizontal position of the microphone body 81 is convenient for rapid positioning. In addition, with the design of the microphone mounting seat 5 and the bell-mouth sound amplification cover 7, on the one hand, the microphone body 81 is protected and has good stability.

Therefore, when the microphone body 81 needs to be maintained later, the microphone body 81 is convenient to disassemble, maintain and replace.

[0048] The locking assembly 9 includes a pin 91 movably inserted into the microphone mounting base 5 and a threaded tube 92 fixedly connected to the microphone mounting base 5.

When the locking assembly 9 is needed to install and lock the microphone body 81, first align the mounting docking block 8 with the interior of the positioning sleeve 51 for clamping. After it is fully clamped, rotate the second threaded rod 93 so that the second threaded rod 93 pushes the pin 91 to move, and the pin 91 is finally inserted into the locking hole 82, so as to realize the quick installation and locking of the microphone body 81.
