[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 fixture 3, and then the electric telescopic rod 409 on the first blade fixture 3 works, thereby pushing the arc pressure plate 410 to squeeze the discarded wind turbine blade, thereby fixing one end of the discarded wind turbine blade, and then controlling the first motor 104 to work, thereby driving the gear in the first reduction box 103 to rotate, thereby driving the first screw rod 102 to rotate, and using the first screw rod 102 to rotate, thereby driving the first slider 402 to move in the first slide groove 101, thereby driving the second blade fixture 4 to move on the track 5, thereby inserting the second blade fixture 4 into the other end of the discarded wind turbine blade, and then the electric telescopic rod 409 on the second blade fixture 4 works, thereby pushing the arc pressure plate 410 to squeeze the other end of the discarded wind turbine blade, thereby using the first blade fixture 3 and the second blade fixture 4 to fix the entire discarded wind turbine blade;

[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. 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. The fourth motor 604 drives the gear in the third reduction box 603 to rotate, 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 groove 6, realizing the movement of the column, thereby driving the entire dragon The movement of the gantry 2 can realize the longitudinal movement of the water knife, so that the water knife 206 can be adjusted to a suitable position, thereby realizing the cutting process of the discarded wind turbine blades. When 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 can be rotated to drive the clamp plate 411 fixed with the clamp gear 408 to rotate. The rotation of the clamp plate 411 can drive the discarded wind turbine blades to rotate, so that the water knife 206 can cut the discarded wind turbine blades as a whole.

[0039] The above embodiments only express the implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
