[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown, a moisture-proof device for a wind turbine cabin includes a protective installation component 1, a humidity monitoring component 2 is installed on the outer wall of the protective installation component 1, and a cable fixing component 3 is connected to the side of the protective installation component 1; the humidity monitoring component 2 includes a humidity sensor 201, a processor 202, a telescopic shell 203, a sliding inner core 204, a power supply 205, a rotating piece 206, and a control power supply 207. The humidity monitoring component 2 is convenient for real-time monitoring of the humidity in the wind turbine cabin. When the humidity in the wind turbine cabin is too high, the fan 103 will be operated, thereby reducing the humidity in the wind turbine cabin, and the sliding The inner core 204 forms a sliding structure with the rotating piece 206 through the telescopic shell 203, and the rotating piece 206 forms a rotating structure through the power supply 205 and the control power supply 207; by providing a humidity sensor 201, the humidity sensor 201 will monitor the humidity in the wind turbine cabin in real time, and transmit the monitored data to the processor 202. After processing and analysis by the processor 202, when the humidity in the wind turbine cabin exceeds the set value of the processor 202, the circuit of the fan 103 will be connected, and the operation of the fan 103 can accelerate the air circulation speed, thereby reducing the humidity in the wind turbine cabin.

[0028] like Figure 1 、 Figure 3 and Figure 4As shown, a wind turbine cabin moisture-proof device, a protective installation assembly 1, includes a hatch panel 101, a vent slot 102, a fan 103, a fixing seat 104, a first spring 105, a latch 106, and a lug 107. The protective installation assembly 1 facilitates the removal of the hatch panel 101, thereby facilitating the maintenance of components in the wind turbine cabin. The hatch panel 101 is detachable through the latch 106 and the lug 107, and the latch 106 is elastically structured through the first spring 105 and the fixing seat 104. The fan 103 and the vent slot 104 are connected. 2 forms a connecting structure, and the opening direction of the ventilation groove 102 is set vertically downward, and the fan 103 is electrically connected to the humidity monitoring component 2; by making the latch 106 squeeze the first spring 105, the latch 106 is retracted into the fixing seat 104, at this time the fixing seat 104 can be close to the side of the ear 107, and the latch 106 is loosened, so that the hatch panel 101 can be fixed, and conversely, the hatch panel 101 can be easily disassembled, thereby facilitating the maintenance of the components in the wind turbine nacelle, and the operation is simple and convenient, and easy to use.

[0029] like Figure 1 and Figure 5 As shown, a wind turbine nacelle moisture-proof device, a cable fixing assembly 3, includes a rotating shaft 301, a cable clamp block 302, a U-shaped plate 303, a second spring 304, and a protrusion 305. The cable fixing assembly 3 can reduce the risk of tripping or electric shock caused by loose or disorganized lines by fixing the lines. The cable clamp block 302 forms a rotating structure with the protective installation assembly 1 through the rotating shaft 301, and the cable clamp block 302 forms a detachable structure with the protective installation assembly 1 through the U-shaped plate 303 and the protrusion 305, and the protrusion 305 forms an elastic structure with the U-shaped plate 303, the second spring 304 and the cable clamp block 302; the cable clamp block 302 can fix the lines in the device in an orderly manner. By fixing the lines, the risk of tripping or electric shock caused by loose or disorganized lines can be reduced. In addition, the orderly and fixed lines can make maintenance and repair work easier, allowing maintenance personnel to quickly locate problem lines and improve maintenance efficiency.

[0030] Working principle: First, the lines of the device are placed in the cable clamp block 302 in order. At this time, the cable clamp block 302 is rotated through the rotating shaft 301 and the U-shaped plate 303 is squeezed at the same time. At this time, the U-shaped plate 303 will cause the protrusion 305 to squeeze the second spring 304. Then, the U-shaped plate 303 can be inserted into the corresponding hole on the side of the hatch plate 101. At this time, the U-shaped plate 303 is released. The protrusion 305 will pop out under the elastic force of the second spring 304, thereby fixing the cable clamp block 302. Next, the latch 106 is toggled. At this time, the latch 106 will retract into the fixing seat 104 by squeezing the first spring 105. Then, the fixing seat 104 is placed on the side of the ear 107. Then, the latch 106 is released. The latch 106 will pop out under the elastic force of the first spring 105. At this time, the latch 106 will be inserted into the ear 107, so that the hatch plate 101 can be fixed.

[0031] Next, since a humidity sensor 201 is provided in the device, the humidity sensor 201 can identify the humidity in the environment and convert it into a sensor with a usable output signal. At this time, the humidity sensor 201 will monitor the humidity in the wind turbine cabin in real time and transmit the monitored signal to the processor 202. After analysis by the processor 202, when the data received by the processor 202 exceeds the set humidity value, it will start to transmit in the form of an electrical signal, causing the sliding inner core 204 to extend from the telescopic shell 203 and cause the sliding inner core 204 to press against the rotating piece 206. At this time, the rotating piece 206 will rotate around the power supply 205, and then the rotating piece 206 will touch the control power supply 207. Since the power supply 205 can provide electricity, and there is an electrical connection between the control power supply 207 and the fan 103, when the rotating piece 206 touches the control power supply 207, the circuit of the fan 103 will be connected, so that the fan 103 starts to work, and the fan 103 will allow air to enter the wind turbine cabin from the ventilation slot 102. The fan 103 will accelerate the air flow speed in the wind turbine cabin, thereby removing moisture.
