Description

Technical Field

[0001] The present invention relates to the technical field of tower detection and adjustment, and in particular to an automatic detection and adjustment device for the verticality of a wind turbine tower. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which then drives the rotor to rotate, ultimately outputting alternating current. The operating principle of a wind turbine is relatively simple: when wind blows through the rotor, the blades rotate, converting the wind's kinetic energy into mechanical energy for the rotor shaft. This mechanical energy is then transmitted through the main shaft drive chain to the generator, which rotates driven by the rotor shaft, converting the mechanical energy into electrical energy. After processing such as rectification and inversion, this electrical energy can be fed into the power grid for use.

[0003] After searching, the Chinese patent with the announcement number CN214621144U discloses a wind turbine tower verticality detection device, comprising a mounting base, side frames are symmetrically provided on both sides of the top of the mounting base, a battery slot is provided on one side surface of one of the side frames, a battery cover is provided inside the battery slot, one end of the battery cover is connected to the battery slot by a rotating shaft, and fixing plates are symmetrically fixed on both sides of one end of the battery cover, and a fixing groove is provided on the inner wall of the battery slot relative to the position of the fixing plate, and the fixing plate is embedded in the interior of the fixing groove; the connection between the battery cover and the battery slot is greatly enhanced by the designed limiting rod and limiting groove, effectively preventing the battery cover from falling off from the inside of the battery slot and avoiding loss; at the same time, the designed side plate and sliding block enable the user to open and close the battery cover, which is very simple to operate and brings convenience to the user. However, this solution still has the following shortcomings in actual use:

[0004] When testing the verticality of a wind turbine tower, the currently commonly used method is to install professional testing instruments on the outside of the tower. Although this method can obtain the tower's tilt data to a certain extent, it has many shortcomings. First, the installation, debugging and use of the testing instruments and their supporting equipment need to be operated by professional testing personnel. Since the inspection is usually carried out regularly, if the tower tilts during the non-inspection period, the existing technical means cannot capture this change in real time, and therefore cannot issue a timely warning, which may result in potential safety hazards not being discovered and handled in time. Secondly, the tilt of the wind turbine tower is often caused by the vibration generated by the blades during rotation. However, in the current maintenance process, staff need to check and tighten the bolts one by one, which is not only cumbersome and time-consuming, but also if some loose bolts are missed, it may also have an adverse effect on the overall stability of the tower.

[0005] Therefore, it is necessary to design an automatic detection and adjustment device for the verticality of a wind turbine tower to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0077] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0078] Reference Figure 1-8, an automatic detection and adjustment device for the verticality of a wind turbine tower, comprising a tower 1; a base 2, fixedly mounted on the bottom end of the tower 1; a plurality of fixing bolts 3, distributed in a circular array and arranged on the side edges of the top surface of the base 2, and the bottom ends of the fixing bolts 3 are fixedly connected to the foundation; a plurality of fixing nuts 4, respectively threadedly sleeved on the outer walls of the fixing bolts 3 above the base 2; a detection component, arranged on the inner side of the top of the tower 1; a guide rail 6, fixedly sleeved on the outer wall of the bottom end of the tower 1; a moving block 7, slidably arranged on the inner side wall of the guide rail 6; a driving mechanism, arranged between the moving block 7 and the guide rail 6; a cleaning component, arranged on the inner side of the moving block 7 and the guide rail 6; The bottom surface of the moving block 7; four connecting rods 10 are respectively fixedly mounted at the four corners of the top surface of the moving block 7; the servo motor 11 is fixedly mounted on the top of the connecting rod 10; the lifting cylinder 12 is arranged at the output end of the servo motor 11, the lifting cylinder 12 passes through the moving block 7, and the lifting cylinder 12 is threadedly connected to the moving block 7; the connecting component is arranged between the servo motor 11 and the lifting cylinder 12; the one-way bearing 14 is arranged on the inner wall of the bottom end of the lifting cylinder 12; the tightening sleeve 15 is fixedly mounted on the inner side wall of the one-way bearing 14, and the tightening sleeve 15 is adapted to the fixing nut 4; during the use of the tower 1, the verticality of the tower 1 can be checked by the detection component on the top The degree of the tower 1 is monitored in real time, and when the tower 1 is skewed and needs to be adjusted, the driving mechanism can drive the moving block 7 to move along the guide rail 6 to the top of the bolt that needs to be tightened. During the entire movement, the fixing bolts 3 and the fixing nuts 4 within the moving stroke can be cleaned by the cleaning component. After the moving block 7 moves to the position just above the bolt to be tightened, the servo motor 11 is turned on to drive the lifting cylinder 12 to rotate. The lifting cylinder 12 is screwed to the moving block 7. Therefore, when the lifting cylinder 12 rotates, it can move vertically along the moving block 7. When the tightening sleeve 15 inside the lifting cylinder 12 moves to the outer wall of the fixing nut 4, this direction is the one-way bearing 1 4, so the lifting cylinder 12 and the tightening sleeve 15 can rotate synchronously, thereby tightening the fixing nut 4, so that the verticality of the tower 1 can be adjusted. After the verticality adjustment of the tower 1 is completed, the servo motor 11 can be reversed, and the lifting cylinder 12 can be driven to reverse so that the lifting cylinder 12 moves upward and reset. This direction is the free state of the one-way bearing 14. Therefore, when the lifting cylinder 12 rotates, it cannot drive the fixing nut 4 to rotate, so as to avoid affecting the locking condition of the fixing nut 4. At the same time, during the vertical movement of the lifting cylinder 12, the rust inhibitor can be sprayed onto the fixing bolt 3 and the fixing nut 4 through the connecting assembly, thereby further enhancing the protection effect.

[0079] Reference Figure 1 、 Figure 2The detection component includes: a suspension bracket 51, which is fixedly mounted on the inner wall of the tower 1; a suspension rope 52, which is fixedly mounted at the center position of the bottom surface of the suspension bracket 51; an infrared transmitter 53, which is fixedly mounted on the bottom end of the suspension rope 52; a support rod 54, which is fixedly mounted on the inner wall of the tower 1 and is located directly below the suspension bracket 51; a connecting ball head 55, which is fixedly mounted on the end of the support rod 54 away from the end connected to the tower 1; a support plate 56, which is arranged at the top of the support rod 54, and the support plate 56 is coaxial with the suspension bracket 51; a connecting ball groove 57, which is opened on the bottom surface of the support plate 56, and the connecting ball head 55 is movably connected to the connecting ball groove 57, and the outer wall of the connecting ball head 55 is in contact with the inner wall of the connecting ball groove 57; an infrared receiving board 58, which is fixedly mounted on the top surface of the support plate 56, and the infrared receiving board 58 is adapted to the infrared transmitter 53 ; Several counterweights 59 are distributed in a circular array on the bottom surface of the support plate 56; when the tower 1 is in normal use, the infrared rays emitted by the infrared emitter 53 can correspond to the center position of the infrared receiving plate 58, which is marked here as the tower 1 is in a completely vertical state. If the tower 1 is skewed, under the action of gravity, the infrared emitter 53 always remains in a vertical downward state, and with the coordinated use of the connecting ball groove 57 and the connecting ball head 55, the support plate 56 and the infrared receiving plate 58 are always in a horizontal state under the action of the counterweight 59. Therefore, when the tower 1 is skewed, the infrared rays emitted by the infrared emitter 53 are located at a position deviated from the center on the infrared receiving plate 58. The skewness of the tower 1 can be calculated by measuring the position of the infrared rays, ensuring that the staff can know the verticality of the tower 1 in real time.

[0080] Reference Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 The driving mechanism includes: a guide groove 81, which is provided on the inner bottom wall of the guide rail 6; a guide block 82, which is fixedly mounted on the bottom surface of the moving block 7, and the guide block 82 is set to an arc shape adapted to the guide groove 81, and the guide block 82 is slidably connected to the guide groove 81; an annular groove 83, which is provided on the inner top wall of the guide rail 6; a driving motor 84, which is fixedly mounted inside the moving block 7; a driving gear 85, which is fixedly mounted on the output end of the driving motor 84, and the driving gear 85 is located on the inner side of the annular groove 83; a plurality of fixed teeth 86, which are fixedly distributed in an annular array. It is fixedly installed on the inner wall of the annular groove 83, and the driving gear 85 is engaged with the fixed teeth 86, and the fixed teeth 86 are arranged on the inner wall of the annular groove 83 on one side; the driving motor 84 is started to drive the driving gear 85 to rotate. When the driving gear 85 rotates, the driving gear 85 is engaged with the fixed teeth 86, and the moving block 7 is slidably connected to the guide groove 81 in the guide rail 6 through the guide block 82. Therefore, when the driving gear 85 rotates, it can drive the moving block 7 to slide along the guide rail 6, so that the moving block 7 can move to the position directly above the bolt that needs to be tightened.

[0081] Reference Figure 5 、 Figure 6 The cleaning assembly includes: a corrugated guide groove 91, which is opened on the outer wall of the tower 1 and is located below the guide rail 6; a fixed sleeve 92, which is fixedly mounted on the bottom surface of the moving block 7; a lifting rod 93, which is slidably mounted on the inner wall of the fixed sleeve 92; a connecting block 94, which is fixedly mounted on the bottom end of the lifting rod 93; a transmission shaft 95, which is arranged on the side of the connecting block 94, and the transmission shaft 95 is rotatably connected to the penetration, and one end of the transmission shaft 95 extends to the inner side of the corrugated guide groove 91; a driven wheel 96, which is fixedly mounted on one end of the transmission shaft 95 located inside the corrugated guide groove 91, and the wheel diameter of the driven wheel 96 is the same as the inner wall width of the corrugated guide groove 91, and the outer wall of the driven wheel 96 is provided with a number of evenly distributed convex hulls; a mounting seat 97, It is fixedly mounted on the end of the transmission shaft 95 away from the driven wheel 96; a number of paddles 98 are distributed in a circular array and fixed on the outer wall of the mounting seat 97; in the process of the moving block 7 sliding along the guide rail 6, it can drive the fixed sleeve 92, the lifting rod 93, etc. to move synchronously, and when the transmission shaft 95 moves, it can slide along the corrugated guide groove 91 through the driven wheel 96. The convex bulge on the outer wall of the driven wheel 96 can increase the friction between the driven wheel 96 and the inner wall of the corrugated guide groove 91, ensuring that the driven wheel 96 can rotate when moving along the corrugated guide groove 91, and can drive the mounting seat 97 and the paddles 98 to rotate, so that the outer wall of the fixing bolt 3 and the fixing nut 4 within the moving stroke can be blown clean to reduce the accumulation of dust and impurities.

[0082] Reference Figure 7 、 Figure 8The connecting assembly includes: a connecting cylinder 131, which is fixedly mounted on the output end of the servo motor 11, and the top of the lifting cylinder 12 is slidably mounted on the outer wall of the connecting cylinder 131; two guide openings 132, which are symmetrically opened on the outer wall of the connecting cylinder 131; a guide frame 133, which is slidably mounted on the inner wall of the connecting cylinder 131, and the two ends of the guide frame 133 pass through the guide openings 132 and are fixedly connected to the lifting cylinder 12; a pressing bag 134, which is fixedly mounted on the inner bottom wall of the connecting cylinder 131; two nozzles 135, which are symmetrically arranged on the connecting cylinder 131. 1, and the nozzle 135 is connected to the pressing bag 134 through the connecting tube, and the nozzle 135 is arranged at the side of the bottom surface of the connecting tube 131; the storage bag 136 is fixedly sleeved on the top outer wall of the connecting tube 131; the slide 137 is fixedly installed on the top surface of the pressing bag 134, and the outer wall of the slide 137 is in contact with the inner wall of the connecting tube 131; the catheter 138 is arranged between the storage bag 136 and the pressing bag 134, and the two ends of the catheter 138 are respectively connected to the storage bag 136 and the pressing bag 134. The inner wall of the conduit 138 and the connecting pipe are connected, and a one-way valve with opposite flow directions is installed; when the lifting cylinder 12 moves in the vertical direction, the lifting cylinder 12 can drive the guide frame 133 to slide along the guide port 132 on the connecting cylinder 131. When the guide frame 133 slides downward, the guide frame 133 can compress the slide plate 137 at the bottom of the connecting cylinder 131, thereby squeezing the pressing bag 134. Under the action of the one-way valve with opposite flow directions between the connecting pipe and the conduit 138, the pressing bag 134 is squeezed. During the pressing, the rust inhibitor can enter the connecting pipe and be sprayed out along the nozzle 135. After being sprayed out, the rust inhibitor can cover the fixing bolt 3 and the fixing nut 4, further preventing the two from being corroded and achieving the protective effect. When the lifting cylinder 12 moves upward, the guide frame 133 can be separated from the slide 137, and the pressing bag 134 can be reset under the action of its own elastic force. Moreover, under the action of the negative pressure, the rust inhibitor in the storage bag 136 can be drawn into the pressing bag 134 through the conduit 138 so that it can be used again.

[0083] The specific working principle of the present invention is as follows:

[0084] When in use, the tower 1 can be used normally after the erection is completed, and the entire detection assembly is arranged on the top of the tower 1, so that the verticality of the tower 1 can be monitored in real time. Specifically, when the tower 1 is in normal use, the infrared rays emitted by the infrared transmitter 53 can correspond to the center position of the infrared receiving plate 58, which is marked here as the tower 1 is in a completely vertical state. If the tower 1 is skewed, under the action of gravity, the infrared transmitter 53 always remains in a vertical downward state, and under the coordinated use of the connecting ball groove 57 and the connecting ball head 55, the support plate 56 and the infrared receiving plate 58 are always in a horizontal state under the action of the counterweight block 59. Therefore, when the tower 1 is skewed, the infrared rays emitted by the infrared transmitter 53 are located at a position deviated from the center on the infrared receiving plate 58. The skewness of the tower 1 can be calculated by measuring the position of the infrared rays, thereby ensuring that the staff can know the verticality of the tower 1 in real time. The working principle and coordination technology of the infrared transmitter 53 and the infrared receiving plate 58 are existing mature technologies and will not be described in detail here.

[0085] If the tower 1 is skewed, the specific skew of the tower 1 can be known through the cooperation of the infrared transmitter 53 and the infrared receiving board 58. At this time, the control center can start the drive motor 84 to drive the drive gear 85 to rotate. When the drive gear 85 rotates, the drive gear 85 is engaged with the fixed teeth 86, and the moving block 7 is slidably connected to the guide groove 81 in the guide rail 6 through the guide block 82. Therefore, when the drive gear 85 rotates, it can drive the moving block 7 to slide along the guide rail 6, so that the moving block 7 can move to the position just above the bolt that needs to be tightened. At the same time, the moving block When sliding along the guide rail 6, the fixed sleeve 92, the lifting rod 93 and the like can be driven to move synchronously. When the transmission shaft 95 moves, it can slide along the corrugated guide groove 91 through the driven wheel 96. The convex bulge on the outer wall of the driven wheel 96 can increase the friction between the driven wheel 96 and the inner wall of the corrugated guide groove 91, ensuring that the driven wheel 96 can rotate when moving along the corrugated guide groove 91, and can drive the mounting seat 97 and the paddle 98 to rotate, so that the outer wall of the fixing bolt 3 and the fixing nut 4 within the moving range can be blown clean to reduce the accumulation of dust and impurities.

[0086] After the moving block 7 moves to the position just above the bolt to be tightened, the servo motor 11 is turned on and drives the lifting cylinder 12 to rotate through the connecting tube 131. The lifting cylinder 12 is screwed to the moving block 7, so that the lifting cylinder 12 can move vertically along the moving block 7 when it rotates. When the tightening sleeve 15 inside the lifting cylinder 12 moves to the outer wall of the fixing nut 4, this direction is the locking direction of the one-way bearing 14. Therefore, the lifting cylinder 12 and the tightening sleeve 15 can rotate synchronously, thereby tightening the fixing nut 4 so that the verticality of the tower 1 can be adjusted. After the verticality adjustment of the tower 1 is completed, the servo motor 11 can be reversed, and the lifting cylinder 12 can be driven to reverse through the connecting tube 131 to move the lifting cylinder 12 upward and reset. This direction is the free state of the one-way bearing 14. Therefore, when the lifting cylinder 12 rotates, it cannot drive the fixing nut 4 to rotate, thereby avoiding affecting the locking condition of the fixing nut 4.

[0087] When the lifting cylinder 12 moves in the vertical direction, the lifting cylinder 12 can drive the guide frame 133 to slide along the guide port 132 on the connecting cylinder 131. When the guide frame 133 slides downward, the guide frame 133 can compress the slide plate 137 at the bottom of the connecting cylinder 131, thereby squeezing the pressing bag 134. Under the action of the one-way valve in the connecting pipe and the conduit 138 with opposite flow directions, when the pressing bag 134 is squeezed, the rust inhibitor in the pressing bag 134 can enter the connecting pipe and be sprayed out along the nozzle 135. After being sprayed, the rust inhibitor can cover the fixing bolt 3 and the fixing nut 4, further preventing the two from being corroded and achieving a protective effect. When the lifting cylinder 12 moves upward, the guide frame 133 can be separated from the slide plate 137, and the pressing bag 134 can be reset under the action of its own elastic force.
