[0022] As shown in Figure 1 and Figure 2 , the glue collection warehouse 7 bottom end fixedly connected with the fixed rod, the fixed rod bottom end fixedly connected with the base, the base both ends inside are connected with the bolt through thread, the base is fixed on the blade root cover plate of wind turbine blade by tightening the bolt, effectively improves the stability of the glue collection warehouse 7.
[0023] As shown in Figure 1 and Figure 3 , the movable block 12 both ends are fixedly connected with the sliding block, the sliding block outer surface is connected with the inside of the glue collection warehouse 7, prevent the position of movable block 12 from deviating when moving, effectively improve the stability of movable block 12 when moving.

[0025] like Figure 1 and Figure 3 As shown, the width of the movable block 12 is greater than the diameter of the drop hole 13, ensuring that the movable block 12 can block the drop hole 13 and ensure that the movable block 12 can be used normally.
[0026] Working Principle: In actual use, the entire device is first placed inside the wind turbine blade. The base is fixed to the blade root cover plate by tightening the fixing bolts. The fixing rod supports the entire collection device, causing the guide 1 to press against the inner wall of the wind turbine blade, creating a compression state. The rubber ring 15 is locked to the wind turbine blade. The electric telescopic rod 8 is activated, which drives the suction cup 9 to move, causing the suction cup 9 to adhere to the inner wall of the wind turbine blade. The colloid enters the guide 1 along the inner wall of the wind turbine blade. The colloid slides down the inner wall of the guide 1 and flows into the guide pipe 2. After passing through the filter plate 3, internal impurities are filtered out. Then, the colloid acts on the movable plate 6, which applies a force to the spring 5, causing the spring 5 to deform and move the movable plate 6 downward. The movable plate 6 then makes contact with the inner wall of the colloid collection bin 7. A gap is formed, and the colloid flows into the colloid collection chamber 7 through the gap, allowing the colloid to flow into the colloid collection bottle 14 along the drop hole 13. When the colloid collection bottle 14 is full and needs to be removed, the motor 11 is started. The output end of the motor 11 rotates, driving the bidirectional threaded rod 10 to rotate synchronously. The rotation of the bidirectional threaded rod 10 drives the movable blocks 12 at both ends to move relative to each other. The movement of the movable blocks 12 drives the slider to move synchronously inside the colloid collection chamber 7. As the movable blocks 12 move, they will move above the drop hole 13, sealing the drop hole 13. At this time, the colloid collection bottle 14 can be rotated and removed. This effectively seals the drop hole 13, preventing the colloid from flowing out along the drop hole 13 when the colloid collection bottle 14 is disassembled, thus preventing colloid leakage. This effectively improves the colloid collection rate and effectively improves the service life of the internal components.
[0027] Then, because the rubber ring 15 is in close contact with the inner wall of the wind turbine blade, the colloid flowing down along the gap between the guide 1 and the inner wall of the wind turbine blade will be blocked by the rubber ring 15 and enter the interior of the guide shroud 16. After being filtered by the filter screen 18, it will enter the interior of the guide 1 along the connecting pipe 17. This can effectively improve the sealing between the guide 1 and the inner wall of the wind turbine blade, and can collect the colloid in the gap between the guide 1 and the inner wall of the wind turbine blade, thereby preventing pollution and safety hazards caused by colloid leakage.
[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
