Description

Technical Field

[0001] The utility model relates to an installation device, in particular to a highly stable wind turbine installation device applied to the field of wind turbine construction. Background Technique

[0002] As a clean energy utilization technology, wind power generation technology has developed rapidly. A wind turbine is a power device that converts wind energy into mechanical work, the mechanical work drives the rotor to rotate, and finally outputs alternating current. Generally, a wind turbine is composed of components such as a wind wheel, a generator (including a device), a yaw device (tail fin), a tower, a speed limit safety mechanism, and an energy storage device.

[0003] During the installation process of a wind turbine, an installation device is arranged at the lower end of the installation rod of the wind turbine. Most of the existing installation devices limit and fix the fixing rod through a large number of bolts. This installation method not only takes time and effort and affects work efficiency, but when the wind turbine is attacked by strong winds, the bolt connection will bear a large load, easily causing the wind turbine to tilt, the connection to break, etc., thus affecting the use stability of the wind turbine. Content of the Utility Model

[0004] Aiming at the above-mentioned prior art, the technical problem to be solved by the utility model is that most of the existing installation devices limit and fix the installation rod of the wind turbine through a large number of bolts. This installation method not only takes time and effort and affects work efficiency, but the bolt connection is prone to break when subjected to a large load, thus affecting the use of the wind turbine.

[0005] To solve the above problems, the utility model provides a highly stable wind turbine installation device, which includes a pre-embedded column. An embedded component is fixedly sleeved on the outer surface of the pre-embedded column. A plurality of insertion rods are fixedly connected to the lower end of the pre-embedded column and are distributed in a circular array around the central axis of the pre-embedded column. An upper end outer ring of the pre-embedded column is fixedly sleeved with a bottom plate. A fixed ring is fixedly connected to the upper end of the bottom plate. A magnetic ring is fixedly sleeved on the outer ring of the fixed ring. A plurality of limiting plates are arranged inside the fixed ring. One end of the limiting plate away from the fixed ring is fixedly connected with a magnetic block. A plurality of screw rods corresponding to the plurality of limiting plates respectively are arranged on the outer side of the fixed ring. One end of the screw rod close to the fixed ring sequentially threadedly penetrates the fixed ring and the limiting plate. An elastic ring is fixedly connected to the inner wall of the fixed ring. A plurality of limiting holes are drilled in the upper end of the bottom plate and are distributed in a circular array around the central axis of the bottom plate. A support rod is inserted into the limiting hole. A limiting ring is fixedly connected to the outer surface of the support rod. Adjacent two limiting rings are fixedly connected by bolts.

[0006] In the above high-stability wind turbine installation device, during the installation process, there is no need to use a large number of bolts to fix the installation rod of the wind turbine, which effectively improves the installation efficiency. At the same time, the inner and outer walls of the installation rod are fixed, improving the stability of the wind turbine.

[0007] As a further improvement of the present application, the embedded component includes a plurality of cross bars and diagonal bars fixedly connected to the outer surface of the embedded column. The plurality of cross bars and diagonal bars are all distributed in a circular array around the central axis of the embedded column, and the lower end of the diagonal bar is fixedly connected to the uppermost cross bar.

[0008] As a further improvement of the present application, a plurality of vertical bars are fixedly connected to the outer surface of the lowermost cross bar. The upper ends of the vertical bars sequentially penetrate through the plurality of cross bars and the plurality of vertical bars and are fixedly connected to the uppermost vertical bar. An arc-shaped bar is fixedly connected between two adjacent vertical bars.

[0009] As a further improvement of the present application, the limiting plate includes two arc-shaped plates fixedly connected to each other. The arc-shaped plate close to the fixed ring is made of honeycomb-shaped flexible material.

[0010] As another improvement of the present application, the magnetic ring and the magnetic block attract each other, and a plurality of limiting rings can form a complete ring.

[0011] As another improvement of the present application, the support rod and the limiting ring are replaced with a fixing component. The fixing component includes a fixing rod threadedly penetrating through the limiting hole, and a traction ring is fixedly connected to the upper end of the fixing rod.

[0012] In summary, during the actual application process, the embedded component is placed into the foundation pit dug in advance, and then concrete is poured for fixation. Then, the installation rod of the wind turbine is hoisted into the inner part of the fixed ring and positioned above the limiting plate. Then, the screw rod is rotated to drive the limiting plate to move towards the fixed ring until the outer wall of the limiting plate fits against the inner wall of the installation rod. During the movement, the magnetic ring and the magnetic block attract each other, and the outer wall of the installation rod presses against the elastic ring, so that both the inner and outer walls of the installation rod are limited and fixed. The ring formed by a plurality of limiting rings limits the fixing rod, effectively preventing the installation rod from tilting. There is no need to use a large number of bolts to fix the installation rod of the wind turbine, effectively improving the installation efficiency and the stability of the wind turbine.

Specific embodiments

[0023] The following will describe in detail the two embodiments of the present application with reference to the accompanying drawings.

[0024] The first embodiment:

[0025] Figure 1 , Figure 2 and Figure 3 show: A highly stable wind turbine installation device, including an embedded column 1, an embedded component 12 is fixedly sleeved on the outer surface of the embedded column 1, a plurality of insertion rods 2 distributed in a circular array around the central axis of the embedded column 1 are fixedly connected to the lower end of the embedded column 1, a base plate 3 is fixedly sleeved on the upper end of the outer ring of the embedded column 1, the embedded component 12 includes a plurality of cross bars 121 and diagonal bars 122 fixedly connected to the outer surface of the embedded column 1, the plurality of cross bars 121 and diagonal bars 122 are all distributed in a circular array around the central axis of the embedded column 1, the lower end of the diagonal bar 122 is fixedly connected to the uppermost cross bar 121, a plurality of vertical bars 123 are fixedly connected to the outer surface of the lowermost cross bar 121, the upper ends of the vertical bars 123 sequentially penetrate through the plurality of cross bars 121 and the plurality of vertical bars 123 and are fixedly connected to the uppermost vertical bar 123, and an arc bar 124 is fixedly connected between two adjacent vertical bars 123. The stability between the installation device and the ground is improved through the plurality of horizontally and vertically intersecting cross bars 121, diagonal bars 122, vertical bars 123 and arc bars 124, thereby effectively preventing the installation device from shaking and tilting.

[0026] Figure 4 and Figure 5 shows that: A fixing ring 4 is fixedly connected to the upper end of the bottom plate 3. A magnetic ring 5 is fixedly sleeved on the outer ring of the fixing ring 4. A plurality of limiting plates 6 are arranged inside the fixing ring 4. One end of the limiting plate 6 far from the fixing ring 4 is fixedly connected to a magnetic block 7. A plurality of screw rods 8 corresponding to the plurality of limiting plates 6 respectively are arranged on the outer side of the fixing ring 4. One end of the screw rod 8 close to the fixing ring 4 sequentially penetrates through the fixing ring 4 and the limiting plate 6 in a threaded manner. An elastic ring 15 is fixedly connected to the inner wall of the fixing ring 4. The limiting plate 6 includes two arc-shaped plates fixedly connected to each other. The arc-shaped plate close to the fixing ring 4 is made of honeycomb flexible material. When the screw rod 8 rotates, the limiting plate 6 moves towards the fixing ring 4. After the limiting plate 6 contacts the fixing ring 4, the limiting plate 6 deforms until the outer wall of the mounting rod is in close fit with the elastic ring 15. Figure 1 In the figure, A is the mounting rod. The magnetic ring 5 and the magnetic block 7 attract each other, thereby improving the stability of the mounting rod.

[0027] Figure 6 shows that: A plurality of limiting holes 9 distributed in a circular array around the central axis of the bottom plate 3 are drilled in the upper end of the bottom plate 3.

Adjacent two limiting rings 11 are fixedly connected by bolts. The plurality of limiting rings 11 can form a complete ring, thereby effectively avoiding the situation that the mounting rod tilts.

[0028] During use, the embedded component 12 is placed into a pre-dug foundation pit, and then concrete is poured for fixation. Then, the mounting rod of the wind turbine is hoisted into the fixing ring 4 and located above the limiting plate 6. Then, the screw rod 8 is rotated to drive the limiting plate 6 to move towards the fixing ring 4 until the outer wall of the limiting plate 6 is in fit with the inner wall of the mounting rod. During the movement, the magnetic ring 5 and the magnetic block 7 attract each other, and the outer wall of the mounting rod presses the elastic ring 15, so that both the inner and outer walls of the mounting rod are limited and fixed. The ring formed by the plurality of limiting rings 11 limits the mounting rod, effectively avoiding the tilting phenomenon of the mounting rod. There is no need to use a large number of bolts to fix the mounting rod of the wind turbine, effectively improving the installation efficiency and the stability of the wind turbine.

[0033] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the protection scope is not limited to this. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
