The detection component 7 is movably connected to the base 3 through the guide shaft 2 to ensure the accuracy of the movement path of the detection component 7. The detection component 7 is separated from the connecting plate 4.

[0030] The power component 5 passes through the side plate above the base 3 to provide an installation position for the power component 5;

[0031] The reset member 6 is connected to the base 3 via the connecting plate 4;

[0032] The detection component 7 includes a mounting plate 8 and a detection member 9. The mounting plate 8 is movably connected to the side plate of the base 3 through the power component 5 and the guide shaft 2. The detection member 9 passes through the mounting plate 8 to ensure that the detection member 9 can move in the up and down directions to adapt to the surface size of the wind turbine blades. The power component 5 and the reset member 6 are both electrically connected to the external control system to control the operation and stop of both.

[0033] The detection member 9 is movably connected to the mounting plate 8 to ensure that the detection member 9 can move in the up and down directions to adapt to the surface size of the wind turbine blade. The mounting plate 8 is specifically in the form of a rectangular parallelepiped and is made of rigid material.

[0034] There are multiple detection members 9 to ensure good detection accuracy. The mounting plate 8 is provided with through holes 10 to serve as channels for the detection members 9 to move in the up and down directions.

[0035] The detection members 9 are distributed in a linear array along the length direction of the mounting plate 8 , and the via holes 10 are distributed in a linear array along the length direction of the mounting plate 8 .

[0036] The detection member 9 is specifically made of a rigid material to prevent it from being deformed. The detection member 9 is movably connected to the mounting plate 8 through a through hole 10 to ensure that the detection member 9 can move in the up and down directions to adapt to the surface size of the wind turbine blade.

[0037] The detection member 9 is separated from the mounting plate 8 , the cross section of the detection member 9 is polygonal, and the reset member 6 is an adsorption member.

[0038] The bottom surface of the detection member 9 is a plane, and the detection member 9 is specifically a rectangular parallelepiped. The reset member 6 is located directly above the detection member 9 to ensure that the reset member 6 absorbs the detection member 9 to make it contact the connecting plate 4 during the reset process.

[0039] The detection member 9 is made of ferromagnetic material, and the reset member 6 is a magnet, which is used to ensure that the reset member 6 absorbs the detection member 9 and contacts the connecting plate 4 during the reset process.

[0040] The material of the detection member 9 is specifically iron, the reset member 6 is specifically an electromagnet, the number of the reset members 6 is not less than one, and the number of the detection members 9 directly below each reset member 6 is not less than one.

The housing of the motor is connected to the side plate of the base 3.

[0042] The working principle of the utility model is as follows: before using a wind power generation blade surface damage detection device, the wind power generation blade surface damage detection device is installed on the production line, and the external transport mechanism transports the wind power generation blade to be detected to the bottom of the detection component 7, at which time the reset member 6 is energized to adsorb the detection member 9 to make it contact with the connecting plate 4; when the wind power generation blade surface damage detection device is started to be used: the external control system stops energizing the reset member 6, at which time the electromagnetic force of the reset member 6 on the detection member 9 disappears, and the detection member 9 falls and contacts the surface of the wind power generation blade under the action of gravity, and then the external control system stops energizing the reset member 6. The power component 5 starts to work under the control of . During this process, the power component 5 drives the detection component 7 to move on the surface of the wind power blade. During this process, the detection component 7 moves along the length direction of the guide shaft 2 and the power component 5. During this process, the bottom of the detection member 9 contacts the surface of the wind power blade and moves forward on the surface of the wind power blade. During this process, the detection member 9 moves up and down on the through hole of the mounting plate 8 to match the surface size of the wind power blade. When the surface of the wind power blade is not damaged, the power component 5 can drive multiple detection members 9 to move normally on the surface of the wind power blade. A pause will occur. After the power component 5 drives the detection component 7 to move back and forth on the surface of the wind turbine blade for several times, the power component 5 drives the detection component 7 to stop under the reset component 6. The external control system energizes the reset component 6, and the reset component 6 adsorbs the detection component 9 to make it contact with the connecting plate 4. The external transport mechanism transports the detected wind turbine blade to the specified position and places a new wind turbine blade that needs to be inspected. When the surface of the wind turbine blade is bruised, protrusions and pits will appear here. During this process, when the detection component 9 contacts the pits or protrusions on the surface of the wind turbine blade, the detection component 9 interferes with them. At this time, the power component 5 will not be able to drive the detection component 9 to continue moving forward. At this time, the power component 5 drives the detection component 7 to stop on the surface of the wind turbine blade, which proves that the wind turbine blade is unqualified. Then, under the control of the external control system, the power component 5 drives the detection component 7 to reset to the bottom of the reset component 6. At this time, the external control energizes the reset component 6, and the reset component 6 absorbs the detection component 9 in the through hole 10 and moves upward to contact the connecting plate 4. Then, the external transport mechanism transports the unqualified wind turbine blade to the specified position, and transports the new wind turbine blade that needs to be inspected to the inspection position, and repeats the above process until the work is completed.
