[0002] The blade is a high-deterministic, large-market-capacity and clear-profit-mode industry in the wind power component field. With the easing of the supply and demand situation, the wind power blade industry will also change from the mixed battle of many powers to the competition of a few powers, and the wind power blade industry in China is experiencing an industry-wide reshuffle.

[0006] By adopting the above technical solution, the worker starts the motor by stepping on the switch, drives the support table to rotate until the required workpiece (such as a tool box) is close to the construction plate, and then the worker stands on the construction plate, the weight of the worker triggers the weight sensor detection signal and transmits it to the PLC, at the same time, the camera transmits the position information of the tool box relative to the worker to the PLC, the PLC calculates according to the preset algorithm, controls the extension of the movable end of the hydraulic cylinder, drives the push block to press the baffle, drives the cylindrical sleeve and the pad to rise, so as to lift the tool box to the height of the worker's hand.

[0016] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0017] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0018] A convenient large-scale wind turbine blade maintenance device and an operating method thereof provided by some embodiments of the present invention will be described below with reference to the accompanying drawings. Example

[0019] Combine Figure 1-6 As shown, the present invention provides a convenient large-scale wind turbine blade maintenance device and an operating method thereof, comprising a transport mechanism 100 and an electric control mechanism 200. The transport mechanism 100 comprises a trailer 110, a support platform 120 rotatably connected to the trailer 110 via a bearing, a motor 130 connected between the trailer 110 and the support platform 120, a plurality of pads 140 attached to the top of the support platform 120, and a machine assembly 150 disposed on the top of the support platform 120. The electric control mechanism 200 includes a lifting platform 210 provided on one side of the support platform 120 and connected to the top of the trailer 110, a switch 220 connected to the top of the lifting platform 210, and the switch 220 is electrically connected to the motor 130. An adaptation mechanism 300 is provided on the top of the trailer 110.

[0020] Specifically, the adaptation mechanism 300 includes a plurality of cylindrical sleeves 310 respectively installed at the bottom of a plurality of pads 140, a baffle 320 installed inside the cylindrical sleeves 310, a hydraulic cylinder 330 vertically passing through the top of the trailer 110, a push block 340 connected to the movable end of the hydraulic cylinder 330, a plurality of construction plates 360 connected to the top of the lifting platform 210, a weight sensor 350 connected between the plurality of construction plates 360, a bracket 370 provided on the other side of the support platform 120 and connected to the top of the trailer 110, a camera 380 and a PLC 390 connected to the bracket 370, the cylindrical sleeve 310 is slidably plugged into the support platform 120, a plurality of construction plates 360 are connected in series, the hydraulic cylinder 330, the construction plates 360, and the camera 380 are all connected to the PLC 390. LC390 is electrically connected, and the operator starts the motor 130 by stepping on the switch 220 to drive the support table 120 to rotate until the required workpiece (such as the tool box 155) is close to the construction board 360. Then, when the operator stands on the construction board 360, his weight triggers the weight sensor 350 to detect the signal and transmits it to PLC390. At the same time, the camera 380 transmits the position information of the tool box 155 relative to the operator to PLC390. After calculating according to the preset algorithm, PLC390 controls the extension of the movable end of the hydraulic cylinder 330, drives the push block 340 to squeeze the baffle 320, and drives the cylindrical sleeve 310 and the pad 140 to rise, thereby lifting the tool box 155 to the height of the operator's hand. This design effectively avoids frequent squatting, improves comfort and reduces work risks.

[0021] Furthermore, the machine assembly 150 includes a generator 151, an angle grinder 152, a hot air blower 153, a water pump 154, a tool box 155, a paint spraying equipment 156, an air compressor 157, and a vacuum pump 158, which are respectively fixed to the top of multiple pads 140. The angle grinder 152, hot air blower 153, water pump 154, tool box 155, paint spraying equipment 156, air compressor 157, and vacuum pump 158 are all electrically connected to the generator 151. With the support of multiple maintenance equipment, it is convenient for operators to repair wind turbine blades in various damage conditions.

[0022] Furthermore, the camera 380 is disposed between the support platform 120 and the bracket 370, and the PLC 390 is disposed on the other side of the bracket 370. The position of the camera 380 is set so that it will not be blocked by the bracket 370 when shooting. Example

[0023] Combine Figure 1-6 As shown, based on the first embodiment, multiple pads 140 are arranged in a ring at equal intervals, and a triangular spacing is formed between two adjacent pads 140. The layout design of the pads 140 allows the lifting of various instruments without interfering with each other, thereby ensuring the smoothness of maintenance operations. Example

[0024] Combine Figure 1 As shown, in the above embodiment, a plurality of support rods 400 are surrounded on the outside of the support platform 120, and a ball is embedded in the bottom end of the support rod 400. The outer wall of the ball fits with the top of the trailer 110. The support rod 400 cooperates with the ball, which can reduce the load of multiple devices on the support platform 120 and make the support platform 120 rotate more smoothly.

[0025] The working principle and use process of the present invention: When the device is put into actual use, the trailer 110 is driven to the side of the wind turbine blade to be repaired with the assistance of an external vehicle. Subsequently, the operator climbs onto the lifting platform 210, and after the lifting platform 210 raises the operator to a suitable height, the operator leaves the construction board 360. At this time, the operator activates the motor 130 by pressing the switch 220, driving the support platform 120 to rotate until the required workpiece (e.g., the tool box 155) is close to the construction board 360. After the operator returns to the construction board 360, his weight triggers the weight sensor 350 to detect the presence of a person and transmits this signal to the PLC 390. At the same time, the camera 380 captures the position information of the tool box 155 relative to the operator and also transmits it to the PLC 390. The PLC 390 calculates according to a preset algorithm and controls the extension of the movable end of the hydraulic cylinder 330. The push block 340 then squeezes the baffle 320, driving the cylindrical sleeve 310 and the pad 140 to rise, thereby lifting the target tool (tool box 155) to the height of the operator's hand. This design effectively avoids the operator from squatting frequently, improves maintenance comfort, and reduces work risks. When the operator leaves the construction board 360 again, the weight sensor 350 detects that the operator has left, and the PLC 390 controls the movable end of the hydraulic cylinder 330 to retract, so that the push block 340 exits the cylindrical sleeve 310. At this time, the operator can step on the switch 220 to smoothly drive the motor 130 to rotate the support platform 120 and replace the equipment. In this way, the conflict-free switching between the two processes of equipment replacement and equipment height adjustment is achieved, ensuring the smooth progress of the maintenance work.

[0026] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and alterations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
