For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0032] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0033] like Figure 1~Figure 3 As shown, this embodiment proposes a lightning protection conductivity detection device for a wind turbine blade 901, including: a sleeve 1; a connector 2, which is slidably arranged in the sleeve 1, and the connector 2 is used to connect with a lightning arrester; an elastic member 3, whose two ends are respectively arranged on the sleeve 1 and the connector 2, and the elastic member 3 is used to provide a force to keep the connector 2 away from the sleeve 1.

[0034] Optionally, the elastic member 3 is made of conductive material, and the wire 11 is connected to the connector 2 through the elastic member 3 .

[0035] Optionally, it further includes: a suction cup 4, which is arranged on the sleeve 1, and the suction cup 4 is used to adsorb the blade 901.

[0036] Optionally, the sleeve 1 is a braided hose made of ferromagnetic material, and further comprises: an electromagnetic device 5, which is arranged on the sleeve 1. After the electromagnetic device 5 acts, the sleeve 1 is transformed from a hose into a rigid tube.

[0037] Optionally, it further includes: a baffle 6 disposed in the sleeve 1 , and the elastic member 3 is disposed on the sleeve 1 through the baffle 6 .

[0038] Optionally, it further includes: a mechanical arm 7, the sleeve 1 is arranged on the mechanical arm 7, and the mechanical arm 7 is used to drive the sleeve 1 to move.

[0039] Optionally, the mechanical arm 7 and the sleeve 1 are detachably connected.

[0040] In this embodiment, the detection device needs to be used in conjunction with the drone 8 and the resistance tester 10. When the operator wants to detect the wind turbine body 9, first install the mechanical arm 7 on the drone 8, then install the sleeve 1 on the mechanical arm 7, then the operator electrically connects one end of the resistance tester 10 to the ground terminal 902, and then connects the wire 11 to the other end of the resistance tester 10, then the operator passes the wire 11 through the mechanical arm 7, penetrates into the sleeve 1 and connects to one end of the baffle 6, and then connects the two ends of the elastic member 3 to the other end of the baffle 6 and the end of the detector respectively. Then the operator can release the drone 8 and make it fly to a height suitable for the blade 901. When the camera on the drone 8 detects the lightning receptor at the end of the blade 901, the operator can operate the mechanical arm 7 to move the sleeve 1 toward the direction close to the blade 901 and the connector 2 toward the direction close to the lightning receptor, so that the connector 2 and the lightning receptor are connected. The suction cup 4 on the sleeve 1 absorbs the blade 901, and the sleeve 1 and the blade 901 are absorbed and fixed. A closed loop is formed between the ground terminal 902, the resistance tester 10, the wire 11, the elastic member 3, the connector 2, and the lightning receptor 12, and the operator can perform detection. When the connector 2 and the lightning receptor 12 are connected, the operator can operate the electromagnetic device 5. After the electromagnetic device 5 operates, the ferromagnetic material on the sleeve 1 is magnetized. At this time, the ferromagnetic materials on the sleeve 1 are mutually attracted, so that the sleeve 1 is changed from a soft tube to a rigid tube, so that the sleeve 1 is not affected by the surrounding wind force and the movement of the drone 8, and the displacement change of the sleeve 1 caused by the wind or the movement of the drone 8 is reduced, so that the connection between the connector 2 and the lightning receptor 12 is more stable, and the detection data is more convincing. After the detection is completed, the operator can control the drone 8 to fly, so that the suction cup 4 and the blade 901 are separated, and the sleeve 1 and the blade 901 are separated. The setting of the elastic member 3 can provide a buffering effect on the one hand. When the connector 2 and the lightning receptor are connected, the setting of the elastic member 3 can make the connector 2 and the lightning receptor 12 in flexible contact, reducing part of the impact force when the connector 2 and the lightning receptor 12 are in contact. On the other hand, the elastic member 3 is a conductive material, so that the connector 2 forms an electrical connection with the wire 11 and the resistance tester 10 through the elastic member 3. Compared with traditional detection methods, this detection device can perform detection safely, quickly and efficiently. At the same time, this detection device has low cost and can be mass-produced.

[0041] Optionally, the connector 2 comprises: a connecting plate 201 disposed on the elastic member 3; a plurality of strikers 202, which are distributed in an array on the connecting plate 201, and the strikers 202 are used to communicate with the lightning receptor.

[0042] In this embodiment, the connector 2 is composed of a connecting plate 201 and a striker 202. The striker 202 is used to connect to the lightning rod. When the striker 202 contacts the lightning rod, the connecting plate 201 presses the elastic member 3 upward, and the elastic member 3 absorbs part of the impact force, thereby reducing the wear of the striker 202.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
