Description

Technical Field

[0001] The invention belongs to the technical field of wind power generation maintenance equipment, and in particular relates to a maintenance tool for wind power generation construction. Background Art

[0002] Wind power generation equipment is a device that converts wind energy into electrical energy. It is mainly composed of wind rotors, generators, towers, nacelles, etc. The wind rotor captures wind energy to drive the generator to operate, thereby generating electricity. The tower plays a supporting role, allowing the nacelle and blades to be at a suitable height to obtain sufficient wind energy. After a period of use, the tower of the wind power generation equipment is exposed to the outside for a long time. The erosion of wind, sand and rain will damage the paint surface of the outer wall and make it rough, increasing wind resistance. As the wind resistance increases, the force on the tower increases accordingly, which not only affects the power generation efficiency, but also aggravates the fatigue loss of the structure and buries safety hazards. Therefore, it is necessary to polish and repair the partial outer wall of the wind power tower. For example, the authorization announcement number is CN213673429U, which discloses a maintenance tool for wind power construction.

[0003] At present, the grinding and maintenance of wind power generation facility towers face many challenges. In terms of maintenance tools, ropes are often used to suspend workers to the tower to be repaired, and then the workers use hand-held grinding equipment to operate. However, the stability of this tool is poor. Given that wind power generation facilities are often built in places with abundant winds, strong winds frequently hit, which can easily blow the suspension ropes, causing the workers to shake violently during maintenance. At the same time, when the workers use grinding equipment to process the tower surface, the reverse force generated by the grinding will also cause the ropes to shake, which in turn causes the workers to sway. This series of shaking problems not only seriously hinders the efficient advancement of tower grinding and maintenance work, but also poses a hidden danger to the personal safety of the workers, greatly reducing the convenience of wind power generation facility tower grinding and maintenance operations; Furthermore, during the tower grinding and maintenance process, the fine particles produced by grinding fly around and can easily invade the mouth and nose of the workers, which not only affects the comfort of the workers' operation, but also interferes with the efficiency of grinding and maintenance to a certain extent.

The above-mentioned power-on devices and electrical connections are existing technologies and will not be repeated here.

[0026] The operating principle of the present invention is now described as follows: when it is necessary to grind the local surface of the tower of a wind power generation facility, first, the maintenance tool is transferred to the top of the wind power generation facility through the elevator inside the wind power generation facility, and then the maintenance cover on the top of the wind power generation facility is opened, so that the staff and the maintenance tool can be on the outside of the top of the wind power generation facility, and at the same time, the top of the wire rope 610 is fixed inside the top of the wind power generation facility, and then the staff wears a safety rope to enter the maintenance space composed of the L-shaped bottom plate 1, the L-shaped cover plate 2, two L-shaped railings 3 and multiple cross bars 4, and then the staff controls the self-locking motor 65 driving end to rotate through the control panel 23 and the PLC controller 17, the self-locking motor 65 drives the driving rod 62 to rotate, and the driving rod 62 drives the winding wheel 611 to release the wire rope 610, so that the maintenance tool can move along the wind power generation facility. The surface of the facility tower descends and eventually moves to the surface of the wind power facility tower that needs to be repaired. Then the staff controls the self-locking motor 65 to stop rotating through the control panel 23 and the PLC controller 17. At the same time, the arc groove of the positioning roller 19 also contacts the surface of the tower of the wind power facility, increasing the contact area, and the positioning roller 19 can further improve the stability of the maintenance tool lifting process. In addition, the driving rod 62 drives the winding wheel 611 to rotate during the winding of the wire rope 610, and the reciprocating screw rod 61 is rotated through the transmission chain 67 and the two sprocket wheels 66. The reciprocating screw rod 61 drives the wire rope 610 to swing through the screw nut 68 and the moving ring 69 to avoid the situation where the wire rope 610 is wound at the same position of the winding wheel 611 when winding. This mechanism enables the maintenance tool to have the function of automatic lifting and lowering, thereby improving the convenience of using the maintenance tool. Then the staff controls the second electric push rod 79 and the moving ends of the two first electric push rods 71 ​​to extend through the control panel 23 and the PLC controller 17, and pushes the sealing ring 73 at the side end of the fixed cover 72 to be close to the surface of the tower of the wind power generation facility, so that the interior of the fixed cover 72 is in a dark state. At this time, the light sensor 74 cannot detect the light environment, and the light sensor 74 sends a corresponding electrical signal to the PLC controller 17. The PLC controller 17 controls the air pump 78 and the three-way reversing solenoid valve 76 to be energized according to the electrical signal, wherein the power-on time of the three-way reversing solenoid valve 76 is 30 seconds, and the air pump 78 sucks the air in the Y-shaped tube 75 through the three-way reversing solenoid valve 76, and the Y-shaped tube 75 The air in the two fixed covers 72 is sucked to make the fixed covers 72 in a negative pressure state, and the fixed covers 72 and the sealing ring 73 are tightly attached to the tower surface, so as to achieve the purpose of positioning the maintenance tool. The moving end of the second electric push rod 79 extends to push the bottom block 710 and the anti-skid rubber pad 711 to contact the tower surface of the wind power generation facility. The oblique support of the second electric push rod 79 can improve the stability of the maintenance tool, and avoid the maintenance tool being greatly shaken on the tower surface of the wind power generation facility due to the influence of high-altitude wind. After 30 seconds, the three-way reversing solenoid valve 76 is powered off, and the air guide direction of the three-way reversing solenoid valve 76 is changed, so that the three-way reversing solenoid valve 76 is inhaled through the air inlet end connected to the conduit 77; In addition, in the process of the maintenance tool descending along the surface of the tower of the wind power generation facility, the positioning roller 19 is always in contact with the tower surface, and the arc-shaped groove of the positioning roller 19 can expand the contact area with the tower surface. At the same time, the staff controls the second electric push rod 79 to extend the moving end through the control panel 23, and makes the anti-skid rubber pad 711 contact with the tower surface, so as to provide auxiliary support for the maintenance tool, and try to ensure the stability of the maintenance tool when it descends. If the maintenance tool moves along the tower surface and encounters strong winds, the staff will promptly control the fixed cover 72 and the sealing ring 73 of the stabilizing mechanism 7 through the control panel 23 to be negatively adsorbed on the tower surface, so as to achieve the purpose of stabilizing the maintenance tool and avoid the situation where the maintenance tool continues to shake and causes safety accidents to the staff. This mechanism can effectively improve the stability of the maintenance tool in the high-altitude grinding operation on the tower surface of the wind power generation facility, thereby improving the convenience and efficiency of the grinding of the maintenance tool, and also improving the safety of the staff's high-altitude operation; After the maintenance tool is positioned on the tower surface of the wind power generation facility, the staff on the L-shaped bottom plate 1 loosens the fastening bolts 97, so that the control rod 95 can move freely in the sleeve 94, and controls the control rod 95 to move in the sleeve 94 through the handle 96, and the control rod 95 drives the connecting cover 11 and the grinding disc 14 to approach the surface of the wind power generation facility tower that needs to be polished, and controls the drive motor 12 to start through the control panel 23 and the PLC controller 17. The drive motor 12 drives the grinding disc 14 to rotate through the connecting rod 13, and the rotating grinding disc 14 approaches the surface of the wind power generation facility tower that needs to be polished for grinding, and the grinding disc 14 can be adjusted in angle through the adjustment mechanism 9, wherein the rotation of the rotating rod 91, the up and down deflection of the sleeve 94 and the free extension and retraction of the control rod 95 in the sleeve 94 can realize the multi-angle adjustment capability of the grinding disc 14, ensuring The grinding disc 14 can perform grinding processing efficiently and reliably, and the adjustment mechanism 9 supports the grinding disc 14 and the drive motor 12, so that the staff does not need to laboriously hold the grinding equipment by hand, which saves time and effort. During the grinding process, since the maintenance tool is positioned by the stabilizing mechanism 7, the reverse force generated by grinding will not cause the maintenance tool to shake, so that the staff on the maintenance tool can stably grind the surface of the tower of the wind power generation facility. After the grinding disc 14 is finished grinding, the staff controls the drive motor 12 to stop rotating, and limits the control rod 95 by tightening the fastening bolt 97. This mechanism can avoid the situation where the reverse force during the grinding process of the tower surface causes the maintenance tool to be unstable, and further improve the stability of the maintenance tool operation. At the same time, during the grinding process, the staff does not need to laboriously hold the grinding equipment by hand, which improves the convenience, efficiency and comfort of the staff in grinding the surface of the tower of the wind power generation facility. When the grinding disc 14 grinds the surface of the tower of the wind power generation equipment, at this time, the air pump 78 sucks the air in the conduit 77 through the unpowered three-way reversing solenoid valve 76, and the conduit 77 sucks the air inside the dust hood 98, and makes the dust hood 98 in a negative pressure environment, and the fine particles generated by the grinding of the grinding disc 14 are collected by the negative pressure dust hood 98, and the fine particles are finally transported to the position between the two partitions 81 by the conduit 77, the three-way reversing solenoid valve 76 and the air pump 78 along with the air, and then the air passes through the sponge The filter block 83 and the filter screen plate 85 are discharged, while the fine particles are retained by the sponge filter block 83 and the filter screen plate 85, which prevents the fine particles generated by grinding from flying to the mouth and nose of the staff, and also prevents the fine particles generated by grinding from falling to the mouth and nose of the ground staff. This mechanism enables the maintenance tool to have the function of collecting fine particles from grinding, and prevents fine particles from flying to the mouth and nose of the staff, which not only improves the comfort of the staff's work, but also improves the efficiency of the maintenance tool in grinding the tower surface.
