[0027] refer to Figures 1 to 4 A wind turbine blade surface grinding device comprises a frame 1, a guide shaft 2, a power component 3 and a grinding component 4, wherein the two frames 1 are connected via the guide shaft 2 and the power component 3, the grinding component 4 is movably connected to the frame 1 via the guide shaft 2 and the power component 3, and is used to ensure that the grinding component 4 has a good accuracy in the movement path between the two frames 1, and the grinding component 4 is separated from the frame 1, and is used to ensure that relative movement can occur between the two;

[0028] The grinding component 4 is connected to the nut seat on the power component 3 to drive the grinding component 4 to move;

[0029] The grinding component 4 includes a mounting plate 5, a connecting plate 6, a power member 7, a conveyor belt 8 and a grinding mechanism 9. The power member 7 is connected to the mounting plate 5 through the connecting plate 6. The mounting plate 5 is movably connected to the frame 1 through the guide shaft 2 and the power member 3. The power member 7 is connected to the grinding mechanism 9 through the conveyor belt 8 to provide power for the grinding mechanism 9 to rotate. The grinding mechanism 9 passes through the mounting plate 5.

[0030] The grinding mechanism 9 includes an upper portion 10 and a lower portion 11 . The power component 3 and the grinding component 4 are both electrically connected to an external control system for controlling the operation and stop of the two.

[0031] The power member 7 includes a motor and a driving wheel, which are used to provide power for the movement of the conveyor belt 8. The conveyor belt 8 is provided with internal teeth for engaging with the power member 7 and the grinding mechanism 9 to transmit kinetic energy. The upper part 10 is provided with gears, and the cross-section of the lower part 11 is circular, which is used to ensure that the lower part can rotate on the mounting plate 5.

[0032] The driving wheel is connected to the rotating shaft of the motor through a coupling to provide kinetic energy. The internal teeth on the conveyor belt 8 are meshed with the gears of the upper part 10 to provide kinetic energy for the rotation of the upper part 10. The upper part 10 is located above the mounting plate 5, and the lower part 11 is located below the mounting plate 5.

[0033] The driving wheel is specifically a gear, the inner teeth on the conveyor belt 8 are meshed with the gears of multiple upper parts 10, and the end of the lower part 11 is movably connected to the mounting plate 5 through a bearing, so as to ensure that the grinding mechanism 9 can move in the vertical direction, thereby ensuring normal sliding on the curved surface of the wind turbine blade.

[0034] The driving wheel meshes with the inner teeth of the conveyor belt 8 , and the conveyor belt 8 is specifically a synchronous belt. The cross-sectional dimension of the upper part 10 is larger than the cross-sectional dimension of the lower part 11 , so as to prevent the grinding mechanism 9 from falling off the mounting plate 5 .

[0035] The number of the grinding mechanisms 9 is not less than two. The grinding mechanisms 9 and the power member 7 are both engaged with the inner teeth of the conveyor belt 8 to provide power for the grinding mechanisms 9 to rotate. The grinding mechanisms 9 are located between the two frames 1.

[0036] The grinding mechanisms 9 are distributed in a linear array along the length direction of the mounting plate 5 , and the grinding mechanisms 9 are symmetrical with respect to the power component 3 .

[0037] The size of the lower portion 11 of the grinding mechanism 9 is smaller than the size of the connection hole between the grinding mechanism 9 and the mounting plate 5, so as to ensure that the lower portion 11 of the grinding mechanism 9 can move in the vertical direction, thereby ensuring normal sliding on the curved surface of the wind turbine blade. The length direction of the grinding mechanism 9 is perpendicular to the horizontal plane.

[0038] The grinding mechanism 9 is provided with a rounded corner to avoid damaging the surface of the wind turbine blade. The rounded corner is located at the end of the lower part 11 away from the upper part 10 , and the rounded corner is located below the power component 3 and the guide shaft 2 .

[0039] The power component 3 includes a screw and a motor. The end of the screw is movably connected to the two frames 1 through bearings. The nut seat of the screw is connected to the mounting plate 5. The end of the screw is connected to the rotating shaft of the motor through a coupling. The motor is specifically a stepping motor. The housing of the motor is connected to the frame 1.

[0040] The working principle of the utility model is as follows: before using a wind turbine blade surface grinding device, the wind turbine blade surface grinding device is installed on a production line; when using a wind turbine blade surface grinding device, the grinding component 4 is close to one of the frames 1, and the external transport mechanism places the wind turbine blade to be ground under the guide shaft 2 and the power component 3, and then starts the grinding step: under the control of the external control system, the power component 3 works to drive the grinding component 4 to move from one of the frames 1 to the other frame 1 along the guide shaft 2. During this process, the external control system controls the power component 7 to work, and the power component 7 drives multiple grinding mechanisms 9 to rotate synchronously on the mounting plate 5 through the conveyor belt 8, and then the grinding mechanism 9 reaches the top of the wind turbine blade driven by the power component 3. During this process, the power component 3 continues to drive the grinding component 4 to make a linear motion on the wind turbine blade. At the same time, the power component 7 drives Multiple grinding mechanisms 9 rotate synchronously. During this process, the rounded corners of multiple grinding mechanisms 9 contact the surface of the wind turbine blade to grind its surface. When the power component 3 drives the grinding mechanism 9 to reach the limit position, the power component 3 works in reverse under the control of the external control system to drive the grinding mechanism 9 to reset. The power component 3 drives the grinding component 4 to reciprocate on the surface of the wind turbine blade to maintain the above process. During this process, the external transport mechanism pushes the wind turbine blade part to move, so that the grinding mechanism 9 can grind different positions on the surface of the wind turbine blade. The above process is maintained until the grinding step is completed. Under the control of the external control system, the power component 3 drives the grinding component 4 to reset. At this time, the grinding component 4 is close to one of the frames 1. The external transport mechanism transports the ground wind turbine blade to the specified position, and transports the new wind turbine blade that needs to be ground to the bottom of the guide shaft 2 and the power component 3. The above process is repeated until the work is completed.

For ordinary technicians in the technical field of the present invention, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
