In some embodiments, the damper is provided at the pivot shaft 143 to increase the rotation damping of the pivot shaft 143 , so as to reduce the rotational speed of the pivot shaft 143 and avoid collision due to excessive rotational speed. It should be noted that when the platform cover 120 performs the opening action, in the last stage of the opening action, the platform cover 120 needs to reduce the speed of movement quickly to avoid impact, and the platform cover can be made Before the plate 120 completes the opening action, the moving speed is rapidly reduced until when the platform cover 120 is in the fully open position, the moving speed of the platform cover 120 is reduced to zero, thereby reducing the inertia of the platform cover 120 to the driving device 130. shock. Similarly, when the platform cover 120 performs the closing action, in the last stage of the closing action, the platform cover 120 needs to reduce the speed of movement rapidly, and by setting the damper, the platform cover 120 can be closed before the closing action is completed. Rapidly reduce the movement speed until when the platform cover 120 is in the fully closed position, the movement speed of the platform cover 120 is reduced to zero, so that the inertia of the platform cover 120 can reduce the impact.

Further, as shown in FIG. 5 , the middle portion of the second connecting rod 162 has a bent portion 163 . It should be noted that the bending portion 163 can change the extending direction of the second connecting rod 162 , thereby facilitating the movement of the end of the second connecting rod 162 away from the first connecting rod 161 to a target position. When the second link 162 drives the platform cover 120 to move, the platform cover 120 can be switched between different target positions, and the end of the second link 162 away from the first link 161 is easier to reach the target position.

It should be noted that the first magnetic door assembly 181 and the second magnetic door assembly 182 can be used together. For example, when the first magnetic door assembly 181 detects that there is a dynamic target approaching the platform cover 120, the first magnetic door assembly 181 is activated trigger, the main control board 170 sends a control command to control the forward rotation of the driving motor 150 after receiving the trigger signal, the driving motor 150 rotates forward, and through the transmission function of the gear assembly 140 and the connecting rod assembly 160, the connecting rod assembly 160 can drive The platform cover 120 performs an opening action; when the second door magnetic assembly 182 detects that there is a dynamic object leaving the platform cover 120, the second door magnetic assembly 182 is triggered, and the main control board 170 sends a control drive motor 150 after receiving the trigger signal. The reverse control command drives the motor 150 to reverse, and through the transmission function of the gear assembly 140 and the connecting rod assembly 160, the connecting rod assembly 160 can drive the platform cover 120 to perform the closing action.

In some examples, the first magnetic door assembly 181 may include a plurality of magnetic door detection pieces, and the multiple magnetic door detection pieces may be spaced apart along the extending direction of the track 180 . The plurality of door magnetic detection parts can detect detection information including electromagnetic signals, and when a dynamic target approaches, the door magnetic detection parts can detect changes in electromagnetic signals. It should be noted that the dynamic target can be an operator or a crawler. When the dynamic target is close to the first door magnetic assembly 181, a plurality of door magnetic detection parts of the first door magnetic assembly 181 will monitor the dynamic target and send the detection information Sent to the main control board 170, when the dynamic target is approaching the platform cover plate 120, the main control board 170 sends a control command to control the forward rotation of the drive motor 150, and the drive motor 150 rotates forward, and through the gear assembly 140, the connecting rod assembly 160 The transmission function enables the link assembly 160 to drive the platform cover 120 to perform an opening action. Likewise, the second magnetic door assembly 182 may also include a plurality of magnetic door detection pieces, and the multiple magnetic door detection pieces may be spaced apart along the extending direction of the track 180 . The plurality of door magnetic detection parts can detect detection information including electromagnetic signals, and when a dynamic target approaches, the door magnetic detection parts can detect changes in electromagnetic signals. When the dynamic target is close to the second door magnetic assembly 182, a plurality of door magnetic detectors of the second magnetic door assembly 182 monitor the dynamic target, and send the detection information to the main control board 170, when the dynamic target is leaving the platform cover At 120, the main control board 170 sends out a control command to control the reverse rotation of the driving motor 150, and the driving motor 150 reverses, and through the transmission function of the gear assembly 140 and the connecting rod assembly 160, the connecting rod assembly 160 can drive the platform cover plate 120 Execute the shutdown action.

It should be noted that the arrangement of the first magnetic door assembly 181 and the second magnetic door assembly 182 can enable the platform cover 120 to be opened or closed automatically. As a result, the degree of automation of the wind turbine can be increased. In addition, in order to increase the diversity of control modes of the wind power generating set, as shown in FIG. 1 and FIG. 6 , the wind generating set may further include a manual switch assembly. The manual switch assembly is in communication connection with the main control board 170 . In this way, when the manual switch assembly is triggered, a signal to open the platform cover 120 or a signal to close the platform cover 120 can be transmitted to the main control board 170 .

For example, when the operator is operating on the wind turbine platform 110, in order to ensure the personal safety of the operator, the platform cover 120 needs to be closed. At this time, the manual switch assembly can be manually triggered. After the main control board 170 receives the information sent by the manual switch assembly, , to issue a control command to control the reverse rotation of the driving motor 150, so that the platform cover 120 can be switched to the closed state. For another example, when the wind power generator is powered off and the platform cover 120 is open, the manual switch assembly sends a closing signal to close the platform cover 120 , thereby controlling the platform cover 120 to switch to the closed state.

Here, the type of the manual switch component is not specifically limited, for example, the manual switch component may be a mechanical button, a touch button, a mobile terminal, a remote controller, and the like. In order to facilitate the operator to control the manual switch assembly, there can be multiple manual switch assemblies. For example, as shown in FIG. One side, and be installed on the track 180; Another example, as shown in Fig. On the track 180 ; as another example, a plurality of manual switch assemblies can be arranged on one side of the platform cover 120 , and the plurality of manual switch assemblies can be distributed along the track 180 at intervals, or can be arranged at any position on the fan platform 110 .
