Embodiment 1

[0040] Such as figure 1 As shown, the present invention provides a wind turbine foundation anchor bolt derusting device, and the top of the derusting device 6 is connected with a hand-held electric tool 5 . After electrification, the hand-held electric tool 5 drives the derusting device 6 to rotate.

[0041] In addition to relying on basic insulation for protection against electric shock, the hand-held electric tool 5 also adopts zero-connection protection, a metal shell, and the power supply part has insulation performance, and is suitable for dry places.

[0042] Such as figure 2 with image 3 As shown, the rust removal device 6 includes a fixed steel rod 6-1, a rust remover container 6-2, a round steel cylinder 6-3, a steel wire 6-4 and a steel wire fixing device 6-5.

[0043] The top of the round steel cylinder 6-3 is welded with a fixed steel rod 6-1, the top of the round steel cylinder 6-3 is welded or glued with a rust remover container 6-2, and the inside of the ro...

Embodiment 2

[0054]A wind turbine foundation anchor bolt rust removal method, based on the fan foundation anchor bolt rust removal device in the above embodiment, the method includes the following steps:

[0055] Process the fixed steel rod 6-1, rust remover container 6-2, round steel cylinder 6-3, steel wire 6-4 and steel wire fixing device 6-5 in the derusting device 6 in the factory;

[0056] Fix the steel rod 6-1 and the round steel cylinder 6-3 by welding, combine the rust remover container 6-2 and the round steel cylinder 6-3 by welding or gluing;

[0057] Pre-embed several steel wires 6-4 on the steel wire fixing device 6-5, then put them into the inner cavity of the round steel cylinder 6-3 and bond them to the inner wall of the round steel cylinder;

[0058] Transport the derusting device 6 to the project site as a whole, and put the derusting agent in the derusting agent container 6-2;

[0059] Assemble the hand-held electric tool 5 and the derusting device 6 by fixing the steel...

Abstract

The invention relates to the technical field of wind generating set foundations, in particular to a fan foundation anchor bolt rust removal device and method. The device comprises a fixed steel bar, a rust remover container, a round steel cylinder, a steel wire and a steel wire fixing device, wherein the round steel cylinder is of a cylindrical hollow structure with a sealed upper part and an open lower part; the fixed steel bar is arranged at the circle center of the top of the round steel cylinder; the rust remover container is arranged at the non-circle-center position of the top of the round steel cylinder; the steel wire fixing device is arranged in the round steel cylinder, and a plurality of steel wires are arranged on the steel wire fixing device; and the fixed steel bar is connected with a handheld electric tool. Mechanical rust removal and chemical rust removal are fully combined, so that the rust removal problem is more efficiently solved; according to the rust removal device, manual use of a small steel brush is avoided, a large amount of labor force is saved, and the construction time is saved.

Description

technical field [0001] The invention relates to the technical field of wind turbine foundations, in particular to a wind turbine foundation anchor bolt derusting device and method. Background technique [0002] The foundation prestressed anchor bolt assembly is mainly used for the connection between the foundation of the wind power tower and the tower, and is one of the important components to ensure the safety of the structure. Due to the harsh natural environment conditions of the wind power tower, the foundation prestressed anchor bolts exposed in the air are easily corroded, causing potential safety hazards. Therefore, the exposed parts of the foundation prestressed anchor bolts need to be protected against corrosion. The anti-corrosion treatment of the prestressed anchor bolts in the wind power tower foundation is the overall Dacromet treatment at the factory, but during the installation process, the Dacromet anti-corrosion coating of the anchor bolts will be damaged wh...
