Description

Technical Field

[0001] The utility model relates to the technical field of fan detection, in particular to a fan periodic work detection device. Background Art

[0002] During the long-term use of wind turbines, manual regular inspections are often required. When performing flaw detection on the variable pitch bearings of wind turbines, ultrasonic flaw detectors are generally used. The flaw detection work can be performed by placing the flaw detection head close to the inner wall of the teeth. Since the flaw detection head needs to be manually squeezed by hand at all times to make it in close contact with the teeth, and since the teeth are thick, it also needs to be moved a little bit for flaw detection, so the detection work is very slow. At the same time, since there is a lot of lubricating oil between the teeth, a large amount of oil will inevitably adhere to the surface of the hand when the handheld flaw detector is moved, which is not conducive to the staff operating the computer for flaw detection. Therefore, a regular work detection device for wind turbines is proposed to address the above problems. Utility Model Content

[0007] The detection module includes a mounting frame, a fixing ear and a fixing plate, wherein the fixing ears are fixedly connected to the upper and lower sides of the mounting frame, and the insides of the fixing ears are fixedly connected to connecting ropes, and the other side of the connecting rope is wound and fixed to the outside of the nut;

[0008] A fixed plate is fixedly connected to the inside of the installation frame, and a moving component is fixedly connected to one side of the fixed plate, and an extrusion component is also fixedly connected to one side of the moving component. A moving sleeve is slidably connected to the outside of the extrusion component, and a flaw detection head is fixedly connected to the other end of the moving sleeve.

[0009] As an optional solution of the fan periodic operation detection device described in the utility model, wherein: the fixing ears are provided on the upper and lower sides of the installation frame, and the fixing ears are installed on the rear side of the installation frame.

[0010] As an optional solution of the fan periodic operation detection device described in the utility model, wherein: limiting blocks are fixedly connected to both sides of the inner wall of the installation frame, and the limiting blocks are arranged with an arc surface relative to one end face that fits the outer side of the teeth.

[0011] During the long-term use of wind turbines, manual inspection is often required. When performing flaw detection on the variable pitch bearings of wind turbines, ultrasonic flaw detectors are generally used. The flaw detection work can be performed by placing the flaw detection head close to the inner wall of the teeth. The flaw detection head needs to be manually squeezed by hand at all times to make it closely contact with the teeth, and because the teeth are thick, it also needs to be moved a little bit for flaw detection. Therefore, the detection work is very slow. At the same time, due to the large amount of lubricating oil between the teeth, a large amount of oil will inevitably adhere to the surface of the hand when the handheld flaw detector is moved, which is not conducive to the staff operating the computer for flaw detection. When using it, an external power supply is required. When in use, the purpose of the installation frame can be achieved by setting the installation frame, fixing ears and connecting ropes, by placing the installation frame between the teeth and tying it to the outside of the nut through the connecting rope, and at the same time, by starting the moving component, the flaw detection head can be driven to move slowly between the teeth, which is used to fully detect the variable pitch bearing. This setting does not require hands to be stained with oil, is conducive to the staff to operate the computer, and can effectively improve the flaw detection efficiency. The fixing ears are installed on the rear side of the installation frame. At this time, the purpose of fixing the installation frame can be achieved by the connecting rope, and a limit block is set on the inner wall of the installation frame, and one end face of the opposite face of the limit block is set in an arc surface that fits the outer side of the teeth.

[0014] The set motor drives the threaded shaft to rotate, so that the threaded sleeve can move slowly. The threaded sleeve drives the extrusion assembly and the flaw detection head to move slowly, which is used to fully detect the thickness distance of a single tooth of the variable pitch bearing without manual hand-held slow movement. The set guide column and guide sleeve ensure that the threaded sleeve moves smoothly when the threaded sleeve moves, thereby preventing the threaded sleeve from rotating itself.

[0015] As an optional scheme of the fan periodic operation detection device described in the utility model, the extrusion assembly includes a mounting sleeve and a sliding rod, the outer side of the mounting sleeve is fixedly connected to the threaded sleeve, the interior of the mounting sleeve is slidably connected to the sliding rod, one end of the sliding rod is fixedly connected to a sliding plate, and the outer side of the sliding plate is slidably connected to the mounting sleeve, the other end of the sliding rod is fixedly connected to a top plate, a spring is provided on the outer side of the sliding rod, and the outer side of the mounting sleeve is slidably connected to the movable sleeve.

[0016] When the flaw detection head is detecting, the flaw detection head cover is outside the installation frame, and the top plate is squeezed by the set spring, and the top plate squeezes the moving sleeve to move. The moving sleeve can drive the flaw detection head to fit tightly between the teeth to ensure the flaw detection quality, and the set sliding plate effectively prevents the sliding rod from separating from the installation frame.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] When the utility model is in use, the purpose of mounting the frame can be achieved by setting the mounting frame, the fixing ears and the connecting rope, and by tying the mounting frame between the teeth and the outside of the nut through the connecting rope. At the same time, the flaw detection head can be driven to move slowly by starting the moving assembly, so as to fully detect the variable pitch bearing. This setting does not require the hands to be stained with oil, which is conducive to the staff to operate the computer and can effectively improve the flaw detection efficiency.

[0019] The motor drives the threaded shaft to rotate, which can make the threaded sleeve move slowly. The threaded sleeve drives the extrusion assembly and the flaw detection head to move slowly, which is used to fully detect the thickness of a single tooth of the pitch bearing without manual hand-held slow movement.

[0020] The guide post and guide sleeve are provided to ensure that the threaded sleeve moves smoothly when the threaded sleeve moves, thereby preventing the threaded sleeve from rotating itself.

[0021] When the flaw detection head is detecting, the flaw detection head cover is outside the mounting cover, and the top plate is squeezed by the set spring, and the top plate squeezes the moving cover to move. The moving cover can drive the flaw detection head to fit tightly between the teeth to ensure the flaw detection quality, and the set sliding plate effectively prevents the sliding rod from separating from the mounting frame.

[0036] During the long-term use of wind turbines, manual inspection is often required for them. When performing flaw detection on the variable pitch bearings of wind turbines, ultrasonic flaw detectors are generally used. The flaw detection work can be performed by placing the flaw detection head close to the inner wall of the teeth. Since the flaw detection head needs to be manually squeezed by hand at all times to make it in close contact with the teeth, and since the thickness of the teeth is relatively thick, it also needs to be moved a little bit for flaw detection, so the detection work is very slow. At the same time, since there is a lot of lubricating oil between the teeth, a large amount of oil will inevitably adhere to the hand surface when the handheld flaw detector is moved, which is not conducive to the staff operating the computer for flaw detection. When in use, an external power supply is connected.

This setting does not require hands to be stained with oil, which is beneficial for the staff to operate the computer and can effectively improve the flaw detection efficiency. The fixing ear 502 is installed on the rear side of the mounting frame 501.

[0040] The motor 504 drives the threaded shaft 506 to rotate, so that the threaded sleeve 509 can move slowly. The threaded sleeve 509 drives the extrusion assembly and the flaw detection head 512 to move slowly, which is used to fully detect the thickness distance of a single tooth 4 of the variable pitch bearing 1 without manual hand-held slow movement. The guide column 507 and the guide sleeve 508 are ensured to ensure that the threaded sleeve 509 moves smoothly when the threaded sleeve 509 moves, thereby preventing the threaded sleeve 509 from rotating itself.
