Description

Technical Field

[0001] This utility model relates to the field of anchor plate protection technology, and in particular to a protection mechanism for anchor plates of wind turbine units. Background Technology

[0002] As an important piece of equipment in the field of renewable energy, the stable operation of wind turbines is of great significance for ensuring energy supply and environmental protection; the anchor plate is a key basic component supporting the entire unit, which is directly related to the stability and safety of the wind turbine.

[0003] In the initial stages of wind turbine installation, the anchor plates are exposed to harsh natural environments for extended periods. Rainwater erosion can cause the anchor plates to rust and corrode, reducing their structural strength. During concrete pouring, concrete and other materials may splash onto the anchor plates, easily covering the mounting holes and making it difficult to complete bolt installation later. The anchor plates are also susceptible to collisions and damage during transportation and installation. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the background technology by proposing a protective mechanism for the anchor plate of a wind turbine.

[0005] The technical solution of this utility model is a protective mechanism for the anchor plate of a wind turbine, comprising: Multiple protective covers are arranged in a circular array. The bottom and both sides of the protective covers are open. The inner cavity of the protective cover has an isosceles trapezoidal cross-section. One end of the protective cover is connected to a sealing strip, and the other end of the protective cover is provided with a sealing notch that matches the sealing strip. Multiple sets of fixed connection components are used, and adjacent protective covers are detachably connected through fixed connection components.

[0006] Preferably, the upper end of the protective cover has a first perforation.

[0007] Preferably, the fixed connection assembly includes a connecting plate, a connecting bolt, and a wing nut. The connecting plate has a second through hole at both ends. The distance between the midpoints of the two second through holes is equal to the distance between the midpoints of the two adjacent first through holes. The connecting bolt is provided with a limit ring. The wing nut is threadedly connected to the connecting bolt.

[0008] Preferably, sealing gaskets are provided at both ends of the bottom of the connecting plate and at the top of the limiting ring.

[0009] Preferably, when the bottom end of the protective cover is flush with the bottom end of the anchor plate, the inner and outer walls of the protective cover are in contact with the inner and outer sides of the anchor plate, respectively. The protective cover is in contact with the outer side of the anchor plate at one point, and the protective cover is in contact with the inner side of the anchor plate at two points.

[0010] Preferably, the number of protective shields is an even number.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects: 1. The multiple protective covers in this technical solution form a ring-shaped outer shell structure, which can block external dust, rainwater, concrete and other substances from damaging the anchor plate, effectively extending the service life of the anchor plate.

[0012] 2. The sealing strip at the end of the protective cover and the sealing notch fit together, which increases the sealing area between adjacent protective covers and improves the sealing effect.

[0013] 3. Multiple protective covers are detachably connected through a fixed connection assembly, making the installation process simple.

[0014] 4. The inner cavity of the protective cover has an isosceles trapezoidal cross-section, which allows multiple protective covers to be stacked together.

[0020] Example 1 like Figures 1-4 As shown in the figure, the protective mechanism for the anchor plate of the wind turbine unit proposed in this embodiment includes multiple protective covers 1 and multiple sets of fixed connection components.

[0021] Multiple protective covers 1 are arranged in a circular array. The bottom and left and right ends of the protective cover 1 are open. The inner cavity of the protective cover 1 has an isosceles trapezoidal cross-section. One end of the protective cover 1 is connected to a sealing strip 3, and the other end of the protective cover 1 is provided with a sealing notch 102 that matches the sealing strip 3. Adjacent protective covers 1 are detachably connected by a fixed connection assembly. When the bottom end of the protective cover 1 is flush with the bottom end of the anchor plate 7, the inner and outer walls of the protective cover 1 are in contact with the inner and outer sides of the anchor plate 7, respectively. The protective cover 1 is in contact with the outer side of the anchor plate 7 at one point, and the protective cover 1 is in contact with the inner side of the anchor plate 7 at two points. This arrangement allows the anchor plate 7 to horizontally limit the protective cover 1 when it is placed over the outer periphery of the anchor plate 7. The number of protective covers 1 is even, which allows two adjacent connecting plates 2 to be arranged one above the other, and multiple connecting plates 2 to be arranged in an alternating manner.

[0022] The working principle of this technical solution is as follows: The protective mechanism in this technical solution consists of multiple protective covers 1 and multiple sets of fixed connection components. The multiple protective covers 1 form an annular shell structure, which can cover the anchor plate 7 inside. The above design makes the annular shell open only at the bottom, which can provide all-round protection for the anchor plate 7, effectively blocking external dust, rainwater, concrete and other damage to the anchor plate 7, thereby extending the service life of the anchor plate 7.

[0023] During the installation of the protective cover 1, the sealing strip 3 at the end of the protective cover 1 will be inserted into the sealing notch 102 of the adjacent protective cover 1. This design can greatly increase the sealing area between two adjacent protective covers 1 and effectively improve the sealing effect of the protective mechanism. When multiple protective covers 1 are placed around the anchor plate 7, the anchor plate 7 can horizontally limit the protective cover 1. Specifically, when the bottom end of the protective cover 1 is flush with the bottom end of the anchor plate 7, the inner and outer walls of the protective cover 1 are in contact with the inner and outer sides of the anchor plate 7, respectively. One point on the outer side of the protective cover 1 is in contact with the anchor plate 7, and two points on the inner side of the protective cover 1 are in contact with the anchor plate 7. The above structure can achieve horizontal limitation of the anchor plate 7. The inner cavity cross-section of the protective cover 1 in this technical solution is an isosceles trapezoid. The isosceles trapezoidal inner cavity allows multiple protective covers 1 to be stacked together.

[0024] Before placing the protective cover 1 on the outside of the anchor plate 7, first pass the connecting bolt 4 through the first through hole 101 from bottom to top. After the protective cover 1 is placed on the outside of the anchor plate 7, the bottom end of the connecting bolt 4 contacts the anchor plate 7, which can limit the connection bolt 4. Then, pass the upper ends of the two connecting bolts 4 through the two second through holes 201 on the connecting plate 2 respectively. Since the two adjacent connecting plates 2 are staggered, the connecting plate 2 at the lower end needs to be placed first, and then the connecting plate 2 at the upper end needs to be placed. Finally, the multiple wing nuts 6 are threaded to the multiple connecting bolts 4 respectively. By tightening the wing nuts 6, the connecting plate 2 is pressed tightly on the protective cover 1, thereby completing the fixed connection of multiple protective covers 1. It should be added that when installing the last protective cover 1, since the sealing strip 3 is elastic, the operator can push the two protective covers 1 adjacent to the last installed protective cover 1 outward to widen the gap between the two protective covers 1, and then place the last protective cover 1 in the widened gap, thereby completing the smooth installation of multiple protective covers 1.

[0025] Example 2 like Figure 2 and Figure 3 As shown in the figure, the protective mechanism for wind turbine anchor plates proposed in this embodiment has a first through hole 101 at the upper end compared with the first through hole 101. During transportation, the wire can be passed through the multiple first through holes 101 of the stacked multiple protective covers 1 to connect the multiple protective covers 1 together. This not only prevents the protective covers 1 from being lost, but also effectively saves transportation space.

[0026] The fixed connection assembly includes a connecting plate 2, a connecting bolt 4, and a wing nut 6. Both ends of the connecting plate 2 have second through holes 201. The distance between the midpoints of the two second through holes 201 is equal to the distance between the midpoints of the two adjacent first through holes 101. A limiting ring 5 is provided on the connecting bolt 4. The wing nut 6 is threadedly connected to the connecting bolt 4. The fixed connection assembly includes a connecting plate 2, a connecting bolt 4, and a wing nut 6. Both ends of the connecting plate 2 have second through holes 201. The distance between the midpoints of the two second through holes 201 is equal to the distance between the midpoints of the two adjacent first through holes 101. This ensures that the connecting bolt 4 can accurately pass through the first through holes 101 and the second through holes 201, achieving a fixed connection between two adjacent protective covers 1.

[0027] Sealing gaskets are provided at both ends of the bottom of the connecting plate 2 and at the top of the limiting ring 5. The use of sealing gaskets can further improve the sealing performance of the connection parts.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
