Description
Technical Field
[0001] The utility model relates to the technical field of wind turbine blade cutting, in particular to a clamping type waste wind turbine blade cutting device. Background Art
[0002] In the wind power industry, the disposal of discarded wind turbine blades is an urgent issue. With the rapid development of the wind power industry, a large number of wind turbine blades have reached the end of their service life or have been eliminated due to technological updates. These discarded wind turbine blades are large in size, complex in structure, and are usually made of composite materials that are difficult to decompose, posing a huge challenge to recycling. Traditional disposal methods such as landfill or incineration not only occupy a large amount of land resources, but also produce harmful gases, causing serious impacts on the environment. Therefore, the research and development of efficient waste wind turbine blade cutting and recycling technologies has become an important topic at present. These technologies aim to decompose large wind turbine blades into smaller components through precise cutting for subsequent recycling or safe disposal, thereby achieving the goals of effective resource recycling and environmental protection.
[0003] Through searching, the announcement number CN117984387A provides an automatic cutting device for wind turbine blades. The cutting device realizes high-precision automatic and precise cutting operations. By adjusting the position through the traction mechanism, it can cut wind turbine blades of different sizes and shapes. At the same time, it replaces manual cutting operations, reduces the risk of personnel contacting the tool, and improves work efficiency and safety.
[0004] However, the automatic cutting device has the following problems when performing cutting operations:
[0005] 1. When the cutting device is performing cutting operations, the wind turbine blades need to be transported to the operation location in advance, which increases transportation costs, makes cutting inconvenient, and makes the operation complicated.
[0006] 2. The cutting device uses a circular saw component for cutting, which has poor cutting efficiency and is difficult to adapt to the cutting of blades of different sizes. Utility Model Content
