[0031] Embodiment 1

[0032] Referring to Figures 1 to 4 , which is the first embodiment of the present utility model. This embodiment provides a clamping mechanism that can solve the problem of inconvenient movement for staff to stay and check when maintaining the fan. It includes a housing component 100, a driving component 200 arranged on the housing component 100, and a clamping component 300 arranged on the driving component 200. Among them, the driving component 200 includes a rotating assembly 201 and a pushing assembly 202 arranged on the rotating assembly 201.

[0033] Specifically, the rotating assembly 201 includes a driving column 201a, an eccentric column 201b fixedly connected to the driving column 201a, a driving hole 201c opened on the eccentric column 201b, and a limiting ring 201d arranged at the bottom of the driving column 201a. The pushing assembly 202 includes a driving plate 202a, a middle hole 202b opened on the driving plate 202a, a driving spring 202c fixedly connected in the middle hole 202b, and an inclined straight groove 202d opened on the driving plate 202a. The driving column 201a passes through the driving hole 201c and is fixedly connected to the eccentric column 201b. The center of the driving column 201a is different from the center of the eccentric column 201b. The limiting ring 201d is fixedly connected to the driving column 201a, and two inclined straight grooves 202d are symmetrically arranged.

[0034] Further, the clamping member 300 includes a clamping block 301, a push post 302 fixedly connected to the clamping block 301, and a clamping arc surface 303 provided on the clamping block 301. The push post 302 only slides within the inclined straight groove 202d. There are two push posts 302 and two corresponding clamping blocks 301 respectively. The clamping arc surfaces 303 on the two clamping blocks 301 are arranged oppositely. By providing the clamping arc surface 303, it is beneficial to increase the contact area between the clamping block 301 and the staff's rope. Therefore, the clamping block 301 and the staff's rope can be relatively fixed more stably through the clamping arc surface 303. The accommodating member 100 includes a housing assembly 101 and a cover body assembly 102 provided on the housing assembly 101. The housing assembly 101 includes an accommodating plate 101a, a driving groove 101b opened on the accommodating plate 101a, a column accommodating groove 101c opened on the driving groove 101b, an annular limiting groove 101d opened on the side of the column accommodating groove 101c, a limiting movement groove 101e opened on the accommodating plate 101a, and an accommodating through groove 101f opened on the accommodating plate 101a. The driving spring 202c is fixedly connected to the accommodating plate 101a. The driving plate 202a is located within the driving groove 101b, the eccentric column 201b is located within the driving groove 101b, the driving plate 202a is located below the driving groove 101b. One end of the driving column 201a passes through the driving hole 201c and enters the column accommodating groove 101c. The limiting ring 201d is placed within the annular limiting groove 101d. By providing the limiting ring 201d and the annular limiting groove 101d, it is beneficial to limit the driving column 201a, and further limit the eccentric column 201b. The clamping block 301 is placed within the limiting movement groove 101e and slides. By providing the limiting movement groove 101e, it is beneficial to limit the clamping block 301, so that the clamping block 301 can only slide left and right within the limiting movement groove 101e, and further the push post 302 can only move left and right. The diameter of the accommodating through groove 101f is adapted to the rope. The accommodating through groove 101f is used to accommodate the staff's rope, facilitating the sliding of the clamping mechanism on the rope. The cover body assembly 102 includes an accommodating cover 102a and a column groove 102b opened on the accommodating cover 102a. The accommodating cover 102a is fixedly connected to the accommodating plate 101a. The driving column 201a passes through the column groove 102b.

[0035] The clamping arc surfaces 303 of the two groups of clamping blocks 301 are oppositely arranged, and the clamping arc surface 303 is integrally designed in a concave shape.

[0036] When in use, when the clamping mechanism and the rope need to be relatively fixed, the rope is first inserted into the accommodating groove 101f. Under normal conditions, the eccentric column 201b will rotate downward with the driving column 201a as the rotation center under the action of gravity. At this time, the center of the eccentric column 201b moves below the center of the driving column 201a. At this time, the eccentric column 201b will contact the driving plate 202a when rotating, and the driving plate 202a will move downward, and the downward movement of the driving plate 202a will drive the oblique straight groove 202d to move downward. At this time, the driving spring 202c contracts. Since the oblique straight groove 202d is inclined downward toward the center, the downward movement of the oblique straight groove 202d will drive the two push pins 302 to move toward the center. The downward movement of the two push pins 302 drives the clamping block 301 to move toward the center in the limit displacement groove 101e, thereby driving the clamping arc surface 303 to continuously fit with the rope. When the center of the eccentric column 201b moves to the right below the center of the driving column 201a, at this time, the driving plate 202a fits with the bottom wall of the driving groove 101b, and the push pins 302 are pushed downward. 02 moves to the lower end of the oblique straight groove 202d. At this time, the two clamping blocks 301 fix the rope through the squeezing friction between the clamping arc surface 303 and the rope, and then at this time, the staff can check and maintain the wind turbine at this position; when the staff needs to continue to check the wind turbine along the rope, the driving column 201a is rotated upward, and the rotation of the driving column 201a drives the eccentric column 201b to rotate. At this time, the eccentric column 201b rotates along the center of the driving column 201a. When the center of circle 1b gradually rotates to above the center of circle of driving column 201a, driving column 201a no longer contacts driving plate 202a. At this time, driving spring 202c resets and stretches to drive driving plate 202a to move upward. The upward movement of driving plate 202a drives the inclined straight groove 202d to move upward, thereby making the two push columns 302 move outward. The push columns 302 move outward to drive the clamping block 301 to move outward, thereby making the clamping block 301 no longer clamp the rope, and the staff can continue to slide along the rope.

[0037] In summary, the driving component 200 controls the clamping component 300 to clamp the worker's rope, thereby preventing the worker from continuing to descend, so that the worker can stay in the air, which is conducive to detailed inspection and subsequent maintenance of the wind turbine.

[0038] Example 2

[0039] Reference Figures 1 to 4, which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a locking assembly 203. Through the locking assembly 203, the rotation of the driving column 201a can be restricted, preventing the staff from accidentally touching the driving rod when staying in the air for inspection of the fan, causing the driving rod to rotate, and further causing the clamping mechanism to be unable to clamp the rope, resulting in the staff slipping. The driving component 200 further includes a locking assembly 203; the locking assembly 203 includes a ratchet tooth 203a, a rotating surface 203b provided on the ratchet tooth 203a, and a resisting surface 203c provided on the ratchet tooth 203a. The ratchet teeth 203a are evenly arranged in a circle and fixed on the outer wall of the driving shaft. The ratchet teeth 203a are placed in the column groove 102b.

[0040] Furthermore, the cover body assembly 102 further includes a clamping groove 102c opened on the column groove 102b, a limiting spring 102d fixedly connected in the clamping groove 102c, a limiting plate 102e fixedly connected to the limiting spring 102d, a fitting surface 102f provided on the limiting plate 102e, and a clamping surface 102g provided on the limiting plate 102e. Three clamping grooves 102c are opened on the column groove 102b. When the limiting spring 102d is in a normal state, the fitting surface 102f contacts the rotating surface 203b, and the clamping surface 102g contacts the resisting surface 203c. At this time, since the clamping surface 102g abuts against the resisting surface 203c, the driving column 201a cannot rotate.

[0041] During use, when the clamping mechanism is relatively fixed to the rope, at this time, since the clamping surface 102g abuts against the resisting surface 203c, the driving column 201a cannot rotate. Therefore, the eccentric column 201b is also in a fixed state. By manually rotating the driving shaft by the staff, the driving shaft rotates to drive the ratchet teeth 203a to rotate. And since the slopes of the resisting surface 203c and the clamping surface 102g are greater than the slopes of the rotating surface 203b and the fitting surface 102f, the driving shaft can only rotate in one direction during the operation of the staff, and this one-way rotation is a relatively convenient reverse rotation. Therefore, when touching the driving column 201a at this time, without reaching a certain torsional force, the driving column 201a cannot rotate; and when the staff needs to continue to slide along the rope, the staff can conveniently rotate the driving column 201a counterclockwise to enable the staff to continue to slide.

[0042] Embodiment 3

[0043] Refer to Figures 5 to 6, which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a fan rope locking device, which solves the problem that it is not easy to install and disassemble the device on the rope. It includes the clamping mechanism in the above embodiment, including a limiting component 400; the limiting component 400 is arranged on the accommodating component 100, and the limiting component 400 includes a clamping and protecting component 401 and a limiting component 402 arranged on the accommodating component 100.

[0044] Furthermore, the clamping and protecting component 401 includes a limiting plate 401a, a retaining groove 401b arranged on the limiting plate 401a, and a pulling column 401c arranged on the limiting plate 401a; the limiting component 402 includes a vertical groove 402a, a horizontal groove 402b opened on the side of the vertical groove 402a, and a pulling and limiting groove 402c opened on the side of the horizontal groove 402b. The limiting plate 401a is a part of the accommodating plate 101a cut off. Among them, the vertical groove 402a, the horizontal groove 402b, and the pulling and limiting groove 402c are opened on the side plate of the accommodating plate 101a. The depth of the retaining groove 401b is greater than the depth of the displacement limiting groove 101e, and the depth of the retaining groove 401b is adapted to the depth of the pulling and limiting groove 402c. The width of the horizontal groove 402b is adapted to the radius of the accommodating through groove 101f.

[0045] During use, when it is necessary to install the device on the rope, first remove the limiting plate 401a from the accommodating plate 101a through the pulling column 401c, then fit the rope with the accommodating through groove 101f, and then align the pull rod with the vertical groove 402a, so that the pull rod drives the limiting plate 401a to move downward along the direction of the vertical groove 402a. When the pull rod moves to the horizontal groove 402b, push the pull rod inward so that the pull rod slides through the horizontal groove 402b and enters the pulling and limiting groove 402c. At this time, the limiting plate 401a fits with the accommodating plate 101a to clamp the rope into the accommodating through groove 101f. At this time, the pull rod is stuck in the pulling and limiting groove 402c under the action of gravity, so that the position of the limiting plate 401a is limited.

[0046] In summary, by driving the limiting plate 401a to move along the vertical groove 402a, the horizontal groove 402b, and the pulling and limiting groove 402c through the pulling column 401c, the limiting plate 401a can be fixed and separated from the accommodating plate 101a, which is beneficial to the installation and disassembly of the device and the rope.
