Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation installation, in particular to an auxiliary fixing device for wind power generation. Background Technique

[0002] Wind power generation equipment refers to equipment that converts the kinetic energy of wind into electrical energy. During the installation process of wind power generation equipment, an auxiliary fixing device for wind power generation equipment installation is required to provide auxiliary fixing.

[0003] The existing auxiliary fixing device installs a base on the ground. The base is composed of two semi-circular plates. Four column holes are opened on the surface of the base to install fixing rods. The support block one can be fixed on the fixing rod at a suitable position, and then the first fixing sleeve plate is placed from the top. The first fixing sleeve plate falls to the position of the support block one and is fixed. Then the fixing rod is lifted, and the two parts of the base and the first fixing sleeve plate are combined. The fixing plate one fixed on the base and the fixing screw one are used to tighten it, so as to fix the connection part of the wind power generation equipment being installed and achieve the effect of non-shaking fixation. However, the first fixing sleeve plate is fixed on the fixing rod, resulting in a fixed position where the first fixing sleeve plate can be fixed. Since the connection positions on wind power generation equipment of different lengths are different, the auxiliary fixing device is used to fix different connection parts, resulting in poor flexibility and practicability of the auxiliary fixing device.

[0028] A wind power generation device refers to a device that converts the kinetic energy of wind into electrical energy. During the installation process of a wind power generation device, an auxiliary fixing device for installing a wind power generation device is required to provide auxiliary fixation.

[0029] In the related art, the first fixing sleeve plate is fixed on the fixing rod, resulting in a fixed position where the first fixing sleeve plate can be fixed. Since the connection positions on wind power generation devices of different lengths are different, the auxiliary fixing device is used to fix different connection positions, resulting in poor flexibility and practicability of the auxiliary fixing device.

[0030] To solve the problems in the related art to a certain extent, the embodiment of this application provides a wind power generation auxiliary fixing device. When it is necessary to adjust the support plate 22 to fix the connection of the tower barrel, only the output end of the motor 211 is used to drive the first threaded rod 212 to rotate. The rotating first threaded rod 212 drives the support plate 22 to move up and down through the moving block 213, and moves the support plate 22 to the position of the connection of the two tower barrels.

[0031] The following describes this application with reference to the accompanying drawings and specific embodiments:

[0032] Combined Figures 1 - 3 , the embodiment of this application provides a wind power generation auxiliary fixing device, including a device body 1; the device body 1 includes: an adjusting component 2 is arranged on the top of the base 11; a top plate 12 is arranged on the top of the adjusting component 2; a first clamping plate 13 is arranged on the base 11 and the top plate 12; the adjusting component 2 includes: a lifting component 21 is arranged on the top of the base 11; a support plate 22 is arranged on the lifting component 21 and is located between the base 11 and the top plate 12; a support rod 23 is arranged between the base 11 and the top plate 12 and penetrates through the support plate 22; second threaded rods 24 are symmetrically arranged on both sides of the support plate 22 and penetrate through the support plate 22; a second clamping plate 25 is arranged at one end of the second clamping plate 25; a locking component 27 is arranged on the outer side of the second threaded rod 24.

[0033] In use, the base 11, the top plate 12 and the support plate 22 are installed on the outer sides of two wind turbine towers by a crane, and the base 11 is fixed to the ground. At the same time, the first clamping plates 13 on the base 11 and the top plate 12 clamp the two towers. Subsequently, according to the position of the connection between the two towers, the staff moves the support plate 22 to a position above the connection between the two towers through the lifting assembly 21. Then, the staff connects the other end of the second threaded rod 24 through a screwing machine and rotates the second threaded rod 24. The rotating second threaded rod 24 drives the second clamping plate 25 to move towards the outer side of the tower, so as to tightly clamp and fix the upper tower through the two groups of second clamping plates 25 to prevent the upper tower from shaking. Subsequently, the second threaded rod 24 is fixed through the locking assembly 27. After clamping and fixing the upper tower, the staff can install bolts and nuts at the connection of the towers for fixation. After fixation, the wind power auxiliary fixing device can be disassembled. The adjustment assembly 2 facilitates the adjustment of the position of the support plate 22, increases the flexibility and practicability of the wind power auxiliary fixing device, and at the same time ensures the stability of the second clamping plate 25 on the support plate 22 for clamping and fixing the connection of the towers.

[0034] Specifically, this wind power auxiliary fixing device is only applicable to small wind turbines, and the tower of the wind turbine is composed of individual towers.

[0035] Specifically, when it is necessary to continue to fix the connection on the tower, it is necessary to hoist another auxiliary fixing device onto the auxiliary fixing device by a crane for assembly and continue to fix the connection on the tower.

[0036] In some embodiments, sliders 26 are arranged on the outer sides of the second clamping plates 25, and sliding grooves 261 matching the sliders 26 are arranged on the support plate 22 to support the second clamping plates 25, increase the stability of the movement of the second clamping plates 25, and prevent the second clamping plates 25 from rotating along with the second threaded rod 24.

[0037] In some embodiments, anti-slip pads 251 are arranged on the inner sides of the second clamping plates 25 to increase the anti-slip property of the second clamping plates 25 and improve the stability of the second clamping plates 25 for clamping and fixing the connection of the towers.

[0038] In some embodiments, the locking assembly 27 includes: a threaded sleeve 271 sleeved on the outer side of the second threaded rod 24; an extrusion block 272 arranged on one side of the threaded sleeve 271 and located on one side of the support plate 22. The staff rotates the threaded sleeve 271 with a wrench, and the rotating threaded sleeve 271 drives the extrusion block 272 to move towards one side of the support plate 22 and extrude the movement of one side of the support plate 22, thereby fixing the second threaded rod 24 and increasing the stability of the second clamping plate 25 for clamping and fixing the connection of the towers.

[0039] In some embodiments, the lifting assembly 21 includes: a motor 211 disposed on the top of the base 11; a first threaded rod 212 disposed at the output end of the motor 211 and located at the bottom of the top plate 12; a moving block 213 sleeved outside the motor 211 and passing through the support plate 22. The first threaded rod 212 is driven to rotate by the output end of the motor 211, and the rotating first threaded rod 212 drives the support plate 22 to lift and lower through the moving block 213.

[0040] In some embodiments, the base 11 includes: a first fixing plate 111 disposed at the bottom of the motor 211; a second fixing plate 112 disposed on one side of the first fixing plate 111 and rotatably connected to the first fixing plate 111. When installing the base 11, the first fixing plate 111 and the second fixing plate 112 are opened, and the first fixing plate 111 and the second fixing plate 112 are sleeved outside the tower barrel, and then the first fixing plate 111 and the second fixing plate 112 are rotated to be closed.

[0041] Specifically, the structures of the top plate 12 and the support plate 22 are similar to the structure of the base 11, and both are composed of two groups of fixing plates, which is convenient for installation outside the tower barrel.

[0042] In some embodiments, connecting plates 14 are provided at the outer connection joints of the base 11, the top plate 12 and the support plate 22 and are fixed by bolts, which facilitates the disassembly and assembly of the base 11, the top plate 12 and the support plate 22.
