Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine blade cutting, and specifically to a negative pressure dust suction cutting device and method for wind turbine blade processing. Background Technique

[0002] The production of wind turbine blades is divided into three processes: blade shell manufacturing, blade profile trimming, and surface painting. The production technology used for the blade shell is the vacuum infusion process. Reinforcing materials such as fiberglass cloth and core materials are laid in sequence in the blade shell mold, and then the reinforcing materials are vacuum-treated with a vacuum film to ensure that the entire system is a closed vacuum system with a certain negative pressure. Then, the resin penetrates through the feed pipe into the entire reinforcing material and is heated and cured. After the blade is completely cured, it needs to be polished, and then the two polished halves are bonded together.

[0003] However, the existing cutting equipment uses manual methods to polish its edges during use, resulting in low polishing efficiency and poor polishing quality.

[0004] To solve the above defects, in the prior art, a Chinese patent with the publication number CN216940877U discloses a cutting device for wind turbine blade production and preparation, including a bottom box and a top plate. A runway is provided on the upper surface of the top plate, and a moving sleeve is sleeved on the surface of the top plate. A connecting plate is fixedly connected to the inner top wall of the moving sleeve, and a rotating rod is rotatably connected to the surface of the connecting plate. Through the settings of the top plate, runway, moving sleeve, connecting plate, rotating rod, roller, and first motor, the first motor rotates to drive the rotating rod and roller to move along the shape of the runway on the runway. The connecting plate helps to support and fix the first motor and the moving sleeve on the top plate. Through the settings of the air pressure box, air pressure plate, second motor, and cutting wheel, the air pressure box adjusts the height of the air pressure plate, driving the second motor and the cutting wheel to adjust the position relative to the wind turbine blade. The second motor drives the cutting wheel to cut and polish along the wind turbine blade, avoiding the hazards and low production efficiency caused by manual operation.

[0005] In the prior art, a Chinese patent with the publication number CN222710987U discloses a movable wind power blade cutting device, which includes a support column. The lower end of the support column is connected with a plug-in component. By setting the plug-in component, two plug-in through holes are horizontally symmetrically opened on the side surface of the support block of the plug-in component. Two bolt holes are vertically opened on the support block perpendicular to the plug-in through holes. The bolt holes are located above the plug-in through holes and communicate with the plug-in through holes. Internal threads are provided in the bolt holes, and fastening bolts adapted thereto are connected in the bolt holes and external threads are provided on the fastening bolts. The top end of the fastening bolt is fixedly connected with a sleeve, and a hydraulic oil pump is installed on the upper surface of the support block. During use, the forklift forks in front of the forklift are inserted into the plug-in through holes, and then the sleeve at the top end of the fastening bolt is rotated to make the fastening bolt descend in the bolt hole. The bottom end of the fastening bolt presses the forklift forks, so that the entire cutting device is fixed on the forklift forks. The forklift can drive the entire cutting device to move in the wild wind farm, and cut the disassembled and scrapped wind power blades on the spot in the wind farm.

[0006] During the use of the above device, the position of the wind power blade is adjusted by the cutting wheel, so as to facilitate the cutting wheel to cut and polish along the wind power blade. However, a large amount of dust will be generated during the cutting of the blade in the above device. These dusts fly in the air and are easily inhaled into the body by personnel, thus affecting the health of the personnel and causing harm to the health of the human body. Summary of the Invention
