[0047] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0048] In traditional pitch control propeller adjustment devices, since the central control device of the pitch control propeller is in a fixed position, one person needs to observe the pitch and direct another person to adjust the pitch. Errors are prone to occur when two people cooperate and communicate. This disclosure provides a pitch control propeller adjustment device in which the operator can observe the pitch while wirelessly adjusting the propeller pitch, thus realizing wireless operation.

[0049] Figure 1 This is a schematic diagram of a pitch control propeller adjustment device provided in an embodiment of this disclosure. See also: Figure 1 The controllable pitch propeller commissioning device includes: a signal box 10, a signal relay box 20, and a controllable pitch propeller central control unit 30. The signal box 10 and the signal relay box 20 are wirelessly connected, and the signal relay box 20 and the controllable pitch propeller central control unit 30 are wiredly connected.

The control panel 101, the first antenna unit 102, and the power supply unit 103 are electrically connected to the first signal transmission unit 104 (not shown in the figure).

[0051] Figure 3 This is a schematic diagram of the structure of a signal repeater box provided in an embodiment of this disclosure. See also... Figure 3 , Figure 3 From left to right, the diagram shows the front view and the internal module diagram. The signal relay box 20 includes: a second housing 200, a second signal transmission unit 201 located inside the second housing 200, and a second antenna unit 202 located on the surface of the second housing 200. The second signal transmission unit 201 is electrically connected to the second antenna unit 202 and the pitch control propeller central control device 30 (not shown in the figure).

[0052] The first signal transmission unit 104 is used to receive instructions generated by the control panel 101 and send the instructions to the signal relay box 20 through the first antenna unit 102.

[0053] The second signal transmission unit 201 receives the command issued by the signal box 10 through the second antenna unit 202 and transmits the command to the controllable pitch propeller central control device 30.

[0054] In this embodiment, the signal box and signal relay box are wirelessly connected, while the signal relay box and the controllable pitch propeller central control device are wired. This allows the user to send control commands via the signal box from a position where they can observe the propeller pitch. Only one person is needed to observe and control the propeller simultaneously, avoiding the inconvenience of communication and operation between two people. Specifically, the user generates commands through the control panel of the signal box, which are then transmitted via the signal transmission units and antennas of the signal box and signal relay box. Finally, the command is output from the signal relay box to the controllable pitch propeller central control device, which then controls the propeller. This control process is simple, avoids repetitive operations, and saves a significant amount of time.

[0069] In this embodiment of the disclosure, the control button 1011, the forward button 1012, and the reverse button 1013 have indicator lights.

[0070] The indicator light can be a light-emitting diode (LED) indicator light or other types of indicator lights. An illuminated indicator light indicates that the corresponding operation is in progress, while an off indicator light indicates that the corresponding operation has stopped.

[0071] In this implementation, setting indicator lights in the buttons allows operators to more intuitively see the control status, forward and reverse status of the equipment, and make real-time adjustments.
