Description

Technical Field

[0001] The present invention relates to the technical field of wind power flange detection, and particularly to a device for dynamically detecting the ovality of a wind power flange. Background Art

[0002] Wind turbines are important new energy power generation equipment. Their basic structure is to support and install the wind power main engine through a tower barrel, and convert wind energy into electrical energy at high altitude. The main engine of the wind turbine can rotate to adjust the windward side. In order to enable the main engine to rotate, a bearing with a flange is required for connection. Usually, the diameter of the bearing flange is relatively large. To ensure the stability of the main engine, there are high precision requirements for the bearing flange. The bearing flange needs to ensure that the roundness meets the standard to ensure the stability of the flange connection. Currently, the device for dynamically detecting the ovality of the flange is usually used for detection before the installation of the wind turbine. However, after the flange is butted, as the service life increases, its precision will change, which is not convenient for real-time detection of various precision indicators of the flange during the operation of the wind turbine. The detection items involved are cumbersome and inefficient, and it is not convenient to test the clearance between the bearing flanges. As the service life increases, the deformation error of the flange gradually increases, posing a safety hazard. The flange bolts usually rely on manual inspection. Loose bolts in some parts are likely to cause flange deformation and displacement. If not discovered in time, it will further increase the precision deviation of the flange. Summary of the Invention

[0038] In the embodiment of the present disclosure, the rotation detection part 4 includes: a rotation installation cylinder 401, an extrusion protrusion 402 and a detection sliding shaft 403. The rotation installation cylinder 401 is fixedly sleeved inside the inner ring 103 of the flange bearing; an extrusion protrusion 402 is fixedly installed at the bottom of the rotation installation cylinder 401, and the extrusion protrusion 402 is attached to the pressing block 305; the detection sliding shaft 403 is slidably inserted on the rotation installation cylinder 401; a spring is sleeved on the detection sliding shaft 403, and the spring sleeved on the detection sliding shaft 403 is connected between the rotation installation cylinder 401 and the detection sliding shaft 403; the end of the detection sliding shaft 403 is a hemispherical structure; the extrusion protrusion 402 is used to squeeze the pressing block 305; the detection sliding shaft 403 is used to detect the radial and axial displacement of the detection flange 1; the detection control component 5 includes: an adjustment The adjusting mounting frame 501 and the positioning bolt 502 are fixedly mounted on the inner side of the rotating mounting cylinder 401; the adjusting mounting frame 501 is threadedly connected with the positioning bolt 502; the end of the positioning bolt 502 passes through the adjusting mounting frame 501; the detection control component 5 also includes: a detection spacing shaft 503 and a micro switch 504, the detection spacing shaft 503 is slidably inserted on the adjusting mounting frame 501; the end of the positioning bolt 502 is pressed against the detection spacing shaft 503; the end of the detection spacing shaft 503 is fixedly mounted with a micro switch 504; the micro switch 504 is aligned with the detection sliding shaft 403; the micro switch 504 is electrically connected to the alarm control light 204; the detection spacing shaft 503 is used to adjust the trigger position of the micro switch 504, and the rotation detection unit 4 is adopted. It can be installed on the wind turbine for real-time testing. The structure adopts a rotating detection part 4 to perform real-time testing on the axial offset error and radial offset error after the barrel flange 1011 in the wind turbine flange is connected to the flange bearing outer ring 102. The basic requirement that the flange bearing inner ring 103 and the barrel flange 1011 should be coaxial is used to indirectly reflect the roundness of the barrel flange 1011 and the flange bearing outer ring 102. The detection items can be effectively integrated. The radial and axial deviations can be detected at one time by detecting the sliding shaft 403 in conjunction with the detection fixing part 6, thereby improving the detection efficiency. At the same time, the structure is simple and reasonable, the problem response is more direct, and the problem can be repaired in time when it is found to ensure the normal operation of the wind turbine. The detection control part 5 can be used to adjust the alarm The trigger stroke, that is, the sensitivity, further improves the practicality of the present structure. No matter the axial or radial position of the detection slide shaft 403 and the detection ring 601 changes, the detection slide shaft 403 will be axially squeezed through the "V"-shaped groove on the inner side of the detection ring 601 or radially squeezed through the inclined surface of the "V"-shaped groove.

[0039] Embodiment 2, on the basis of Embodiment 1, the detection fixture 6 includes: a detection ring 601 and a rubber ring 602. The detection ring 601 is fixedly installed inside the fan cylinder body 101; a rubber ring 602 is fixedly installed on the detection ring 601, and the rubber ring 602 is attached to the bottom of the inner ring 103 of the flange bearing, playing a role in fitting and dust prevention; a "V"-shaped groove is formed inside the detection ring 601; the clearance detection member 7 includes: a propulsion hydraulic cylinder 701, a plug-in slider 702, and a guide shaft 703. The propulsion hydraulic cylinder 701 is fixedly installed on the rotary mounting cylinder 401; a plug-in slider 702 is fixedly installed on the output shaft of the propulsion hydraulic cylinder 701; the end of the plug-in slider 702 is a bevel structure; the plug-in slider 702 is inserted inside the detection ring 601; guide shafts 703 are respectively fixedly installed on both sides of the plug-in slider 702, and the two guide shafts 703 are respectively inserted on the rotary mounting cylinder 401; the clearance detection member 7 further includes: a brush sponge 704 and an electromagnet 705. Brush sponges 704 are respectively fixedly installed on both sides of the plug-in slider 702, and the brush sponges 704 are attached to the "V"-shaped groove inside the detection ring 601; an electromagnet 705 is fixedly installed inside the plug-in slider 702; the electromagnet 705 is used to magnetically attract the detection ring 601, and the brush sponges 704 are used to wipe and clean the detection ring 601. The clearance detection member 7 can be used to assist in the active stress clearance test work, improve the reliability of the connection between the inner ring 103 of the flange bearing and the outer ring 102 of the flange bearing, can apply stress for testing, and the detection is more labor-saving and convenient. There is no need to remove the inner ring 103 of the flange bearing and the outer ring 102 of the flange bearing, preventing the inner ring 103 of the flange bearing from being pressed against the outer ring 102 of the flange bearing due to the gravity of the main engine installed on the inner ring 103 of the flange bearing, which is too heavy, and it is difficult to achieve the clearance range test manually. This structure can prevent the ovality from gradually increasing after long-term use due to the existence of clearance, causing potential safety hazards. If there is wear clearance between the inner ring 103 of the flange bearing and the outer ring 102 of the flange bearing, the cylinder flange 1011 and the outer ring 102 of the flange bearing will be pulled by the plug-in slider 702, resulting in displacement between them and the inner ring 103 of the flange bearing. At this time, the opposite detection sliding shaft 403 will squeeze the detection ring 601, and the detection sliding shaft 403 can also squeeze the microswitch 504 to control the alarm, realizing the clearance detection work. When the three plug-in sliders 702 are inserted into the detection ring 601, they can play a role in limiting, improving the stability of this structure in dealing with harsh environments.

[0040] Working principle of this embodiment: The distance between the microswitch 504 and the detection sliding shaft 403 is adjusted by the sliding detection adjusting shaft 503. Tighten the positioning bolt 502 to carry out the positioning work. After connecting the main wind turbine to the inner ring 103 of the flange bearing through the flange bolt, when the main wind turbine operates to adjust the windward surface, it drives the rotating installation cylinder 401 to rotate. At this time, the rotating installation cylinder 401 will drive the detection sliding shaft 403 to slide in the "V"-shaped groove inside the detection ring 601. If the rollers between the inner ring 103 and the outer ring 102 of the flange bearing are severely worn, and the inner ring 103 and the outer ring 102 of the flange bearing are no longer in a concentric position relationship, or when the outer ring 102 of the flange bearing and the cylinder flange 1011 have an ovality deformation, the detection ring 601 will also be squeezed to produce an ovality deformation. Under the action of the spring, the detection sliding shaft 403 will fit the detection ring 601. Whether the axial or radial position of the detection sliding shaft 403 and the detection ring 601 changes, it will axially squeeze the detection sliding shaft 403 through the "V"-shaped groove inside the detection ring 601 or radially squeeze the detection sliding shaft 403 through the inclined surface of the "V"-shaped groove. The detection sliding shaft 403 can retract and touch the microswitch 504. At this time, the microswitch 504 can control the alarm control lamp 204 to light up for alarm prompt, which is convenient for the staff to know. The detection sliding shaft 403 during rotation can fit and detect each point inside the detection ring 601. The push-in slider 702 is driven to move by the propulsion hydraulic cylinder 701 opposite to the detection control part 5. During the process, the electromagnet 705 is energized to magnetically attract the detection ring 601. At this time, when the push-in slider 702 moves, it can pull the fan cylinder 101 to move. If there is a wear clearance between the inner ring 103 and the outer ring 102 of the flange bearing, the cylinder flange 1011 on the fan cylinder 101 and the outer ring 102 of the flange bearing will be pulled by the push-in slider 702 to generate a displacement between the inner ring 103 of the flange bearing. At this time, the opposite detection sliding shaft 403 will squeeze the detection ring 601. If the clearance is too large, the detection sliding shaft 403 can also squeeze the microswitch 504 to control the alarm, realizing the clearance detection work. When the rotating installation cylinder 401 is driven to rotate by the main engine, it can drive the push-in slider 702 to rotate to switch different detection positions. The staff can perform the detection work regularly. At the same time, during the rotation of the push-in slider 702, the detection ring 601 can be wiped by the brush sponge 704. When the three push-in sliders 702 are driven to insert into the detection ring 601 but do not frictionally fit the detection ring 601, it can play a limiting role and is used for reinforcement work in bad weather. Rotate and open the liquid supplement bolt 203 to carry out the oil injection work for the first use of the liquid passing installation pipe 201. When the main wind turbine drives the inner ring 103 of the flange bearing to rotate, it drives the rotating detection part 4 to squeeze the pressing block 305, realizing the downward movement of the pressing plate 304, compressing the support spring 306, and realizing the downward pressure on the pressure air bag 302. The air pressure is introduced into the liquid passing installation pipe 201 through the hose to test the bolt connection and sealing effect of each part on the outer ring 102 of the flange bearing in real time. Once the bolt becomes loose,The oil will penetrate into the inner part of the outer ring 102 of the flange bearing. At this time, the oil volume inside the liquid supply installation pipe 201 decreases, and the tightness of the bolt connection can be known in time.
