[0037] Working principle: A rotary water jet cutting device for discarded wind turbine blades. When working, the discarded wind turbine blades are first installed, and one end of the discarded wind turbine blade is first inserted into the first blade clamp 3. Then, the electric telescopic rod 409 on the first blade clamp 3 is operated to push the arc pressure plate 410 to squeeze the discarded wind turbine blade, thereby fixing one end of the discarded wind turbine blade. Then, the first motor 104 is controlled to drive the gear in the first reduction gear box 103 to rotate, thereby driving the first screw rod 102 to rotate. The rotation of the first screw rod 102 drives the first slider 402 to move in the first slide groove 101, thereby driving the second blade clamp 4 to move on the rail 5, thereby inserting the second blade clamp 4 into the other end of the discarded wind turbine blade. Then, the electric telescopic rod 409 on the second blade clamp 4 is operated to push the arc pressure plate 410 to squeeze the other end of the discarded wind turbine blade, thereby fixing the entire discarded wind turbine blade by using the first blade clamp 3 and the second blade clamp 4.
[0038] The second motor 209 is used to drive the gear in the second reduction box 208 to rotate, thereby driving the second screw rod 210 to rotate around the bearing, so that the lifting frame 201 moves up and down, and the third motor 204 is powered on to work, thereby driving the third screw rod 205 to rotate around the bearing, so that the water jet 206 on the water jet installer 202 moves horizontally, and the gear in the third reduction box 603 is driven to rotate by the fourth motor 604, thereby driving the fourth screw rod 601 connected to the gear in the third reduction box 603 to rotate. The rotation of the fourth screw rod 601 will drive the fourth slider 602 to move in the fourth slide 6, realizing the movement of the column, thereby driving the entire dragon The movement of the gantry 2 drives the longitudinal movement of the water jet, so that the water jet 206 can be adjusted to a suitable position, thereby realizing the cutting process of the discarded wind turbine blades. During cutting, the fifth motor 401 on the first blade clamp 3 and the second blade clamp 4 can be operated to drive the first gear 403, the second gear 404, and the third gear 405 to rotate. The first gear 403, the second gear 404, and the third gear 405 are rotated to drive the clamp disk 411 fixed with the clamp gear 408 to rotate. The rotation of the clamp disk 411 drives the discarded wind turbine blades to rotate, allowing the water jet 206 to cut the discarded wind turbine blades as a whole.
[0039] The above embodiments merely illustrate the implementation methods of the present invention. Although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
