Description

Technical Field

[0001] The invention relates to the technical field of pipeline passivation equipment, in particular to offshore wind power generator motor cooling pipeline passivation equipment. Background Art

[0002] A wind turbine is an electric device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. A wind turbine is generally composed of components such as a wind wheel, a motor, a rectifier, a tower, a speed limit safety mechanism, and an energy storage device. When the motor is in use, the heat inside the motor will be high due to the influence of natural conditions such as offshore wind speed and salt spray. At this time, a cooling pipe is needed to assist in the heat discharge in the motor. Coolant flows in the cooling pipe, and the surface of the cooling pipe is easily affected by natural conditions at sea. Therefore, the cooling pipe needs to be passivated to increase the service life of the cooling pipe, thereby ensuring the normal use of offshore wind power generators. Pipeline passivation is a special treatment technology for eliminating surfactants on the surface of metal materials. The purpose of passivation is to protect the surface of the pipe and prevent the pipe from being corroded during use, thereby extending the service life of the pipe. Passivation is achieved by forming a dense passivation film on the surface of the pipe. This film can effectively isolate the pipe from corrosive substances that may exist in the environment, thereby reducing the corrosion rate of the pipe.

[0003] At present, the passivation of pipelines is usually carried out by immersing the pipelines in a passivation tank, so that the inner and outer surfaces of the pipelines are passivated by immersing the pipelines in the passivation liquid. Before the passivation treatment, the staff usually needs to use a degreasing agent and a pickling liquid to clean the surface of the pipeline, and a cleaning liquid is needed between each processing step so that the subsequent passivation liquid can better treat the pipeline surface. During the degreasing, pickling and passivation process, the pipeline is immersed in the degreasing agent, the pickling liquid and the passivation liquid. After the pipeline is lifted from the degreasing agent, the pickling liquid and the passivation liquid, the degreasing agent in the pipeline , pickling liquid and passivation liquid will be discharged from both ends, but since the pipeline is set horizontally, some degreasing agent, pickling liquid and passivation liquid will remain in the pipeline. The degreasing agent, pickling liquid and passivation liquid will enter the next processing step with the pipeline, which will not only cause waste of materials, but also affect the cleaning liquid. In addition, the remaining degreasing agent, pickling liquid and passivation liquid in the pipeline are easy to spill to the outside with the movement of the pipeline and pollute the surrounding working environment, and the passivation agent is easy to cause damage to the respiratory tract and skin of the staff. The remaining passivation agent inside and on the surface of the pipeline is easy to cause harm to the staff when unloading. Summary of the invention

Then, under the action of the elastic force of the tension spring 373, the piston plate 372 is reset, and the air in the rectangular box 36 is discharged through the vent head 382. At this time, the flow of air can accelerate the cleaning speed of the passivation liquid on the surface of the pipe body 41 below, so as to reduce the residue of the passivation liquid on the surface of the pipe body 41.

[0041] Working principle: The staff first injects degreasing agent, cleaning liquid, pickling liquid, cleaning liquid and passivation liquid into the interior of several liquid storage tanks 4 respectively, and then places the pipeline body 41 inside the support plate 28. After that, under the action of the counterweight rod 291, the slide plate 292 drives the protective plate 293 to descend, and the protective plate 293 descends to cooperate with the support plate 28 to limit the pipeline body 41. At this time, the outer frame 25 is placed inside the liquid storage tank 4 on one side and immersed in the degreasing agent. After that, the staff can first start the drive motor 81 located at the bottom, and the rotating shaft 84 will move accordingly. The winding drum 11 is driven to rotate, and the winding drum 11 is relaxed as the pull rope 121 is wound, and the force plate 122 drives the limit plate 123 to descend, and the L-shaped frame 14 and the card plate 15 are placed on one side of the card frame 34. After that, the staff starts the driving motor 81 located at the top, and the mobile frame 5 moves accordingly, and the card plate 15 moves to the bottom of the card frame 34. Then the staff starts the driving motor 81 located at the bottom to work in the reverse direction. The L-shaped frame 14, the card plate 15 and the card frame 34 can be used together to drive the outer frame 25 to lift, and the pipeline body 41 is removed from the degreasing agent. At the same time, the lower wedge block 39 is moved with The thin plate 18 and the thick plate 21 are lifted, and the lower wedge block 39 cooperates with the upper wedge block 40 to drive the thin plate 18 and the thick plate 21 to move. One end of the exhaust pipe 222 is sheathed on one end of the pipeline body 41, and the positioning plate 19 moves with the thin plate 18 and limits the other end of the pipeline body 41. After that, the staff starts the air pump 23, and the hose 24 can inject the air inside the rectangular box 36 into the inner wall of the air delivery pipe 221 through the air guide pipe 223. The exhaust pipe 222 discharges the degreasing agent inside the pipeline body 41 through the push of the air flow, and the arc plate 20 re-introduces the degreasing agent into the liquid storage tank 4. At the same time, the auxiliary mechanism 37 cooperates with the air intake mechanism 38 to drive the air flow below the top frame 31, so as to accelerate the cleaning of the remaining degreasing agent on the surface of the pipeline body 41 for subsequent use. Then the staff drives the moving frame 5 to move through the cooperation of the driving mechanism 8, the gear ring 9 and the gear plate 10, so as to move the outer frame 25 to the top of another liquid storage tank 4. Thereafter, the staff starts the driving motor 81 located below to work in reverse, and the outer frame 25 descends and is placed in the adjacent liquid storage tank 4, so as to clean the remaining degreasing agent on the surface of the pipeline body 41 with the cleaning liquid;

[0042] The staff repeats the above operation to pickle and passivate the surface of the pipe body 41. The degreasing and pickling can clean the surface of the pipe body 41. During the passivation process, the pipe body 41 is immersed in the passivation liquid to be passivated. Thereafter, the exhaust mechanism 22 and the air pump 23 cooperate to discharge the remaining passivation liquid in the pipe body 41. At the same time, the auxiliary mechanism 37 and the air intake mechanism 38 cooperate to accelerate the cleaning of the remaining passivation liquid on the surface of the pipe body 41. The cleaned and discharged passivation liquid can be returned to the interior of the liquid storage tank 4 for subsequent use, thereby reducing Less passivation liquid is spilled to the outside and causes material waste and pollution to the working environment. In addition, the staff can observe the surface of the pipe body 41 to make a preliminary observation on the passivation effect of the pipe body 41. The auxiliary mechanism 37 and the air intake mechanism 38 cooperate to accelerate the cleaning of the passivation liquid on the surface of the pipe body 41, which can facilitate the staff to better clean the surface of the pipe body 41. When the pipe passivation treatment is completed, the staff lifts the counterweight rod 291 to release the limit of the protective plate 293 on the pipe. After that, the staff can pull out the pipe body 41 to unload the pipe body 41.
