Dust removal device for polishing of root ends of wind power generation blades

Abstract

The invention relates to a dust removal device for polishing of root ends of wind power generation blades. The dust removal device comprises a protective cover placed at a polished position of a root end of a blade, the protective cover consists of a dust removal cover used for preventing dust generated during polishing from diffusing, the dust removal cover is placed beside the polished position by the aid of a fixing device, a drawer type baffle plate used for preventing the dust from falling on the blade is placed below the dust removal cover, a sponge cushion used for realizing a form-following sealing effect is further disposed at a contact position of the lower side of the dust removal cover and the blade, and a dust collector for removing the dust is connected with the inside of the dust removal cover. The dust removal device has the advantages that baffle plates with various shapes can be manufactured to be used when different areas of blades are polished, dust is effectively prevented from falling into the blades, and the dust baffle plates can be replaced at any time.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a dust removal device used for root end grinding of wind power blades. Background technique [0002] At present, most of the blade designs are made of glass fiber reinforced epoxy resin as its main material, which is vacuum infused. In the process of vacuum infusion, it is difficult to cut the root end cloth layer accurately, so the root end needs to be polished after the infusion is solidified. The dust generated when the glass fiber composite material is polished will fall on the surface of the product, which will have a great impact on the surface cleaning, sizing, and mold closing of the product. In severe cases, it will even cause cracking of the blade mold joint, and the product will be scrapped. The most important thing is that these dusts are very harmful to the human body, which can easily cause the human body to suffer from respiratory diseases and threaten life safety. Conte...
