The first driving mechanism is connected to the horizontal sliding member 11 and drives the horizontal sliding member 11 to slide in the horizontal direction.

[0020] The vertical base 1 is fixedly connected above the horizontal sliding member 11. The first driving mechanism drives the horizontal sliding member 11 to slide synchronously with the vertical base 1. The side of the vertical base 1 is slidably connected to the vertical sliding member 4. The interior of the vertical base 1 is connected to the second driving mechanism, which is connected to the vertical sliding member 4 and drives the vertical sliding member 4 to slide in the vertical direction.

[0021] The robot body includes a base 3, a robotic arm 7, a water-cutting head 8, and a sand tank 5. The base 3 is fixedly connected to a vertical sliding member 4. The base 3 is also fixedly connected to the body of a motor 6. The output shaft of the motor 6 is fixedly connected to the robotic arm 7. The water-cutting head 8 is connected to the end of the robotic arm 7. The sand tank 5 is fixedly connected to the base 3. The water-cutting head 8 has a mixing chamber and a water inlet, a sand inlet, and a spray nozzle connected to the mixing chamber. The water inlet is connected to a water tank through a water supply hose, and the sand inlet is connected to the sand tank 5 through a sand supply pipe.

[0022] This invention, through the configuration of a horizontal base 10, a vertical base 1, a horizontal sliding member 11, a vertical sliding member 4, and a robotic arm 7, enables multi-angle cutting of decommissioned wind turbine blades. By incorporating a water-jet cutting head 8 and a sand tank 5, water and sand are mixed and then jet-cut, increasing the jet force and easily cutting the wind turbine blades, reducing the cutting difficulty, and eliminating dust generation.

[0023] Furthermore, the first and second drive mechanisms can be hydraulic mechanisms or conventional drive mechanisms such as motors with gears and racks.

[0024] Furthermore, the water supply hose is a high-pressure hose.

[0025] In some embodiments, such as Figure 1 , 2 As shown, a hose limiting clamp 9 is fixedly connected to the robotic arm 7 to limit the water supply hose.

[0026] In some embodiments, as shown in Figure 2 The hose limiting clip 9 is provided with a plurality of limiting holes 92, and the water supply hose is threaded through the limiting holes 92. This facilitates the guidance of the water supply hose.
