[0023] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figure 1-Figure 7 The utility model provides a technical solution: an installation component of a wind turbine equipment monitoring device, comprising: a cross bar 2, the cross bar 2 is fixed at a high position on the inner wall of a tower 1, two groups of through holes 3 are opened on the surface of the cross bar 2, the two groups of through holes 3 are symmetrically distributed about the cross bar 2, a rope 8 is movably inserted in the through hole 3, a monitoring device 7 is arranged at one end of the rope 8, a balance bar 11 is fixed to the other end of the rope 8, a hinge 12 is fixed to the other end of the balance bar 11, a winch 13 is arranged at the other end of the hinge 12, the winch 13 is rotatably connected to the surface of a winch seat 14, and the winch seat 14 is fixed at a low position on the inner wall of the tower 1.

[0026] In actual use, the monitoring device 7 is hoisted at the bottom end of the crossbar 2 by a rope 8 movably inserted in the through hole 3. The monitoring device 7 exerts a downward pulling force on one end of the rope 8 fixed on the monitoring device 7 under its own weight. This pulling force is transmitted to the balance bar 11 and then converted into an upward pulling force of the rope 8 on the balance bar 11. The pulling force is then transmitted from the balance bar 11 to the hinge 12 and then converted into a pulling force that causes the hinge 12 to rotate away from the winch 13. When the monitoring device 7 is not under maintenance, the winch 13 is in a locked state and cannot rotate. When the monitoring device 7 needs to be repaired, the maintenance personnel only need to enter the tower 1, stand at a low position, unlock the winch 13, and rotate the winch 13 to make the winch 13 wound on the winch rotate. The hinge 12 on 13 is gradually rotated away from the winch 13, so that the monitoring device 7 can gradually descend in height under the action of its own gravity, until the monitoring device 7 descends to a low place, and the maintenance personnel can stand at a low place to inspect the monitoring device 7. When the height of the monitoring device 7 decreases, the rope 8 drives the balance bar 11 to rise, and the balance bar 11 drives the hinge 12 to be more rotated away from the winch 13. After the maintenance is completed, the winch 13 is rotated in the opposite direction to make the hinge 12 more coiled on the surface of the winch 13, so that the height of the balance bar 11 decreases, and the movement of the balance bar 11 pulls the monitoring device 7 upward through the rope 8, until the monitoring device 7 returns to its original height, and then the winch 13 is locked again to complete the maintenance.

[0027] Embodiment 2

[0028] On the basis of Example 1, in order to prevent the monitoring device 7 from shaking under the cross bar 2, a sleeve 4 is fixed at the position where a through hole 3 is opened at the bottom end of the cross bar 2, and a round table 6 is fixed to one end of the rope 8 where the monitoring device 7 is provided, and a plug-in rod 5 is fixed to the bottom end of the round table 6, and the plug-in rod 5 is fixed to the top of the monitoring device 7.

[0029] When the monitoring device 7 is hoisted under the cross bar 2, the plug-in rod 5 is inserted into the sleeve 4 fixed at the bottom end of the cross bar 2. The inner wall of the sleeve 4 limits the plug-in rod 5, so that the plug-in rod 5 can only move up and down in the sleeve 4. This limit is transmitted to the monitoring device 7 through the plug-in rod 5 to prevent the monitoring device 7 from shaking when it is hoisted at the bottom end of the cross bar 2. At the same time, a round table 6 is fixed on the top of the plug-in rod 5, so as to prevent the top of the plug-in rod 5 from being stuck at the bottom end of the sleeve 4 and unable to be inserted when the plug-in rod 5 is inserted into the sleeve 4.

[0030] Embodiment 3

[0031] On the basis of the second embodiment, in order to reduce the friction of the rope 8, the top end of the cross bar 2 is rotatably connected to the first pulley 9, and the side of the cross bar 2 is rotatably connected to the second pulley 10, and the rope 8 is overlapped on the surface of the first pulley 9 and the second pulley 10.

[0032] The first pulley 9 and the second pulley 10 are rotatably connected on the surface of the cross bar 2, so that the rope 8 is overlapped on the first pulley 9 and the second pulley 10, so that the friction force generated on the surface of the rope 8 is rolling friction. If the first pulley 9 and the second pulley 10 are not provided, sliding friction will occur between the rope 8 and the cross bar 2. Therefore, the first pulley 9 and the second pulley 10 can greatly reduce the magnitude of the friction force on the rope 8.

[0033] Embodiment 4

[0034] On the basis of the third embodiment, in order to facilitate the rotation of the winch 13, winch shafts 15 are provided at both ends of the winch 13, and an axial hole is opened on the surface of the winch seat 14. The winch shaft 15 is rotatably connected in the axial hole of the winch seat 14, and a handle 16 is fixed on the surface of one end of one group of winch shafts 15 away from the winch 13.

[0035] The capstan shaft 15 in the shaft hole of the capstan seat 14 can be rotated by rotating the handle 16 , and the capstan shaft 15 drives the capstan 13 to rotate.

[0036] Embodiment 5

[0037] On the basis of the fourth embodiment, in order to lock and unlock the capstan 13, a screw hole is opened on the surface of the capstan seat 14, and a locking screw 17 is rotatably connected in the screw hole of the capstan seat 14. A locking groove 18 is opened on the surface of the capstan 13, and the locking screw 17 is movably inserted in the locking groove 18.

[0038] After inserting the plug-in rod 5 at the top of the monitoring device 7 into the sleeve 4, fine-tune the capstan 13 so that the locking groove 18 on the surface of the capstan 13 is aligned with the screw hole on the surface of the capstan seat 14, and then screw the locking screw 17 into the screw hole of the capstan seat 14 and continue to screw it into the locking groove 18, so that the capstan 13 can be locked; when the capstan 13 needs to be unlocked, the locking screw 17 needs to be reversed to withdraw the locking screw 17 from the locking groove 18 and the screw hole of the capstan seat 14, so that the capstan 13 can be unlocked.

[0039] In actual use, the monitoring device 7 is hoisted at the bottom end of the crossbar 2 by a rope 8 movably inserted in the through hole 3. The monitoring device 7 exerts a downward pulling force on one end of the rope 8 fixed on the monitoring device 7 under its own weight. This pulling force is transmitted to the balance pole 11 and then converted into an upward pulling force of the rope 8 on the balance pole 11. The pulling force is then transmitted from the balance pole 11 to the hinge 12 and then converted into a pulling force that causes the hinge 12 to rotate away from the winch 13. When the monitoring device 7 is not under maintenance, the winch 13 is in a locked state and cannot rotate. When the monitoring device 7 needs to be repaired, the maintenance personnel only need to enter the tower 1, stand at a low position, unlock the winch 13, and rotate the winch 13, so that the hinge 12 wound on the winch 13 is gradually rotated away from the winch 13, that is, The monitoring device 7 can be gradually lowered under the action of its own gravity until the monitoring device 7 is lowered to a lower position. The maintenance personnel can then stand at a lower position to perform maintenance on the monitoring device 7. When the height of the monitoring device 7 is lowered, the rope 8 drives the balance bar 11 to rise, and the balance bar 11 drives the hinge 12 to rotate more away from the winch 13. After the maintenance is completed, the winch 13 is rotated in the opposite direction to make the hinge 12 more coiled on the surface of the winch 13. Then, the height of the balance bar 11 is lowered, and the movement of the balance bar 11 pulls the monitoring device 7 upward through the rope 8 until the monitoring device 7 returns to its original height. The maintenance is then completed by relocking the winch 13. When the monitoring device 7 is hoisted below the crossbar 2, the plug-in rod 5 is inserted into the sleeve 4 fixed at the bottom end of the crossbar 2. The inner wall of 4 limits the insertion rod 5, so that the insertion rod 5 can only move up and down when it is in the sleeve 4. This limit is transmitted to the monitoring device 7 through the insertion rod 5 to prevent the monitoring device 7 from shaking when it is hoisted at the bottom end of the cross bar 2. At the same time, a round table 6 is fixed to the top of the insertion rod 5, so as to prevent the top of the insertion rod 5 from being stuck at the bottom end of the sleeve 4 and unable to be inserted when the insertion rod 5 is inserted into the sleeve 4; the first pulley 9 and the second pulley 10 are rotatably connected to the surface of the cross bar 2, so that the rope 8 is overlapped on the first pulley 9 and the second pulley 10, so that the friction force generated on the surface of the rope 8 is rolling friction. If the first pulley 9 and the second pulley 10 are not provided, sliding friction will occur between the rope 8 and the cross bar 2, so The friction force on the rope 8 can be greatly reduced by the first pulley 9 and the second pulley 10; the capstan shaft 15 in the axial hole of the capstan seat 14 can be rotated by rotating the handle 16, and the capstan 13 can be driven to rotate by the capstan shaft 15; after the plug-in rod 5 at the top of the monitoring device 7 is inserted into the sleeve 4, the capstan 13 is fine-tuned so that the locking groove 18 on the surface of the capstan 13 is aligned with the screw hole on the surface of the capstan seat 14, and then the locking screw 17 is screwed into the screw hole of the capstan seat 14 and continued to be screwed into the locking groove 18, so that the capstan 13 can be locked; when the capstan 13 needs to be unlocked, the locking screw 17 needs to be reversed to make the locking screw 17 withdraw from the locking groove 18 and the screw hole of the capstan seat 14, so that the lock of the capstan 13 can be unlocked.
