However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a device for blade lightning current monitoring, including a mounting plate 1, a top plate 2 is fixedly connected to the bottom of the mounting plate 1, a frame 3 is fixedly connected to the bottom of the top plate 2, a plurality of connection seats 6 are evenly fixedly connected to the bottom of the frame 3, a plurality of connection seats 6 are arranged inside the plurality of connection seats 6, a plurality of traction ropes 9 are arranged on the outer surfaces of the plurality of traction ropes 8, a bottom frame 13 is fixedly connected between the end surfaces of the plurality of traction ropes 9, a host 17 is arranged at the bottom of the bottom frame 13, a battery 18 is fixedly connected to the bottom of the bottom frame 13, a motor 4 is fixedly connected to the outer surface of the frame 3, an output end of the motor 4 slides through the frame 3 and extends to the inside, and a rotating shaft is fixedly connected to the output end of the motor 4 5, the end face of the rotating shaft 5 is rotatably connected to the inner surface of the frame 3, the outer surface of the rotating shaft 5 is symmetrically fixedly connected with the first pulley 10, the inner surface of the frame 3 is symmetrically rotatably connected with the supporting shaft 7, the supporting shaft 7 and the connecting seat 6 are slidably connected, the wire wheel 8 is fixedly connected to the outer surface of the supporting shaft 7, the bottom of the bottom frame 13 is fixedly connected with a hinge, the outer surface of the hinge is fixedly connected with a protective cover 14, the outer surface of the protective cover 14 is fixedly connected with a first lock buckle 15, the outer surface of the bottom frame 13 is fixedly connected with a second lock buckle 16, the first lock buckle 15 and the second lock buckle 16 are matched, the bottom frame 13 is located at the outer side of the host 17 and the battery 18, and the host 17 and the battery 18 are electrically connected.

[0024] The effect achieved by the entire embodiment 1 is that when the blade lightning current monitoring device is used, it is installed at a high installation position of the blade by using the mounting plate 1. When the bottom frame 13 and the top plate 2 are in a fitted state, the main machine 17 is at a high altitude position where the blade is located to monitor the lightning current. It can monitor in real time whether the blade is struck by lightning, take measures to protect the power generation equipment in time, and ensure the normal operation of the wind power generation system. When the main machine 17 needs to be maintained, the starting motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 can drive the first pulley 10 to rotate with it. When the first pulley 10 rotates, it can drive the support shaft 7 to rotate with it through the connection between the belt 12 and the second pulley 11. The support shaft 7 drives the wire wheel 8 to rotate. When the wire wheel 8 rotates, the traction rope 9 can be released. When the traction rope 9 is released, the bottom frame 13 can be moved toward the ground, thereby driving the main machine 17 to move to the ground position. After the main machine 17 moves to the ground position, it is convenient for the staff to directly view the data of the main machine 17 and complete maintenance operations on the main machine 17.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, a second pulley 11 is fixedly connected to the outer surface of the support shaft 7 , and a belt 12 is sleeved between the outer surfaces of the first pulley 10 and the second pulley 11 .

[0026] The effect achieved by the entire embodiment 2 is that the motor 4 drives the rotating shaft 5 to rotate synchronously to drive the supporting shafts 7 on both sides to rotate, the four wire wheels 8 can rotate synchronously to release the wire, and the four traction ropes 9 are used to fix the bottom frame 13 for retraction and release. This can make the up and down movement of the bottom frame 13 more stable, avoid the main machine 17 from being damaged by collision during the lifting process, and play a better protective role for the device.

[0027] Working principle: When the blade lightning current monitoring device is in use, it is installed at a high installation position of the blade by using the mounting plate 1. When the bottom frame 13 and the top plate 2 are in a fitted state, the main machine 17 is at a high altitude position where the blade is located to monitor the lightning current. It can monitor in real time whether the blade is struck by lightning, and take timely measures to protect the power generation equipment to ensure the normal operation of the wind power generation system. When the main machine 17 needs maintenance, the starting motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 can drive the first pulley 10 to rotate with it. When the first pulley 10 rotates, it can drive the support shaft 7 to rotate with it through the connection between the belt 12 and the second pulley 11. The support shaft 7 drives the wire wheel 8 to rotate. When the wire wheel 8 rotates, the traction rope 9 can be released. When the traction rope 9 is released, the bottom frame 13 can be moved toward the ground, thereby driving the main machine 17 to move. The main frame 17 is located on the ground, and after the main frame 17 is moved to the ground, the staff can directly view the data of the main frame 17 and complete the maintenance operation on the main frame 17. After the maintenance operation is completed, the protective cover 14 is covered and fixed, and then the motor 4 is started to reverse to raise the bottom frame 13 to a high altitude position for lightning current monitoring. When the lightning current monitoring device is in use, there is no need for the staff to climb to a high place to maintain the main frame 17. The maintenance work of the lightning current monitoring device saves time and has a lower work risk. The motor 4 drives the rotating shaft 5 to rotate when the supporting shafts 7 on both sides are driven to rotate. The four wire wheels 8 can rotate synchronously for releasing the wire. The bottom frame 13 is fixed by four traction ropes 9 for retracting and releasing. The up and down movement of the bottom frame 13 is relatively stable, which avoids the main frame 17 from being damaged by collision during the lifting process, and has a better protective effect on the device.
