Description
Technical Field
[0001] This utility model belongs to the field of anchor bolt technology, and particularly relates to an anchor bolt type wind power foundation stabilization device. Background Technology
[0002] Anchored wind turbine foundation stabilization devices are foundation structures used to fix wind turbine generator sets. They mainly use anchors to firmly connect the wind turbine structure to the ground to reduce vibration and swaying of the wind turbine, ensuring the stability and safety of the wind turbine. The anchors are usually made of high-strength materials and can withstand large tensile and shear forces to ensure the safe operation of the wind turbine generator set.
[0003] Based on the above, the inventors have discovered the following shortcomings in existing anchor-type wind power foundation stabilization devices:
[0004] 1. The mating parts of the anchor bolt and nut are exposed to the outside, making them susceptible to corrosion under the influence of dust and rainwater. It is inconvenient to install protective measures on the anchor bolt to cover the mating parts of the anchor bolt and nut.
[0005] 2. The tightness of the nuts on the anchor bolts cannot be displayed, making it difficult for staff to quickly determine whether the nuts are loose. It is also inconvenient to set up indicators on the nuts to quickly determine whether the nuts are loose. Utility Model Content
[0006] To address the aforementioned technical problems, this utility model provides an anchor bolt-type wind power foundation stabilization device. This solves the issues of existing anchor bolts and nuts being exposed to the outside, making them susceptible to corrosion from dust and rain, and the inconvenience of adding protective measures to cover the anchor bolt and nut mating parts. Furthermore, the lack of indication of nut tightness on the anchor bolt makes it difficult for workers to quickly determine if the nut is loose, and it is inconvenient to install indicators on the nut to quickly determine if it is loose.
[0007] The purpose and effectiveness of this utility model's anchor-type wind power foundation stabilization device are achieved through the following specific technical means:
[0008] An anchored wind power foundation stabilization device includes a device body; the device body is provided with a closed protective cap in the vertical direction, the lower end of the closed protective cap is provided with a flared mouth, the top end face of the closed protective cap is provided with a regular hexagonal prism, and the bottom end face of the regular hexagonal prism of the closed protective cap is provided with a threaded blind hole.
[0009] Furthermore, a waterproof sleeve is provided around the top end face of the fixing hole of the fan structure plate, and a front-to-back indicator groove is provided in front of the top end face of the waterproof sleeve of the fan structure plate.
[0010] Furthermore, the lower part of the threaded rod of the prestressed anchor bolt is fitted with a fan structure plate, and the fan structure plate has a through-hole in the middle.
[0011] Furthermore, the threaded rod of the prestressed anchor bolt is fitted with an elastic anti-loosening ring in the middle. The elastic anti-loosening ring is a spiral open ring plate structure, and a corrosion-resistant layer is provided on the surface of the elastic anti-loosening ring.
[0012] Furthermore, the upper part of the threaded rod of the prestressed anchor bolt is threaded with a fan plate pressure cylinder in the vertical direction. The fan plate pressure cylinder has a threaded inner circumference and a regular hexagonal structure on the outer circumference. An indicator groove in the vertical direction is opened in front of the outer circumference of the fan plate pressure cylinder.
[0013] Furthermore, the prestressed anchor bolt is surrounded by an anchor bolt protective tube running vertically around its outer circumference. The surface of the anchor bolt protective tube is provided with a corrosion-resistant layer, and the ends of the anchor bolt protective tube are chamfered.
[0014] Furthermore, a prestressed anchor bolt in the vertical direction is installed inside the threaded blind hole of the closed protective cap, and a threaded rod is provided on the top end face of the prestressed anchor bolt, and a frustum is provided on the top end face of the threaded rod of the prestressed anchor bolt.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] The convenient sealing cap is installed on the end of the prestressed anchor bolt via threads. It can easily cover the fan plate pressure cylinder and seal it in contact with the fan structure plate. This solves the problem that the mating parts of the anchor bolt and nut are exposed to the outside and are prone to corrosion under the action of dust and rainwater. It is also inconvenient to install protective measures on the anchor bolt to cover the mating parts of the anchor bolt and nut.
[0017] The system facilitates the alignment of the indicator slots on the fan plate pressure cylinder and the fan structure plate to achieve locking. When the indicator slots do not align, the fan plate pressure cylinder becomes loose. This solves the problem that the tightness of the nuts on the anchor bolts cannot be displayed, making it difficult for workers to quickly determine whether the nuts are loose. It also addresses the inconvenience of setting indicators on the nuts to quickly determine whether the nuts are loose. Attached Figure Description

[0025] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.
[0026] Example 1:
[0027] As attached Figure 1 To be continued Figure 6 As shown:
[0028] This utility model provides an anchor-type wind turbine foundation stabilization device, including a device body 1. The device body 1 is provided with a vertically enclosed protective cap 2 to facilitate protection of the wind turbine plate pressure cylinder 5. The lower end of the enclosed protective cap 2 is provided with a flared opening to facilitate fitting with the waterproof cylinder of the wind turbine structure plate 7. The top end face of the enclosed protective cap 2 is provided with a regular hexagonal prism to facilitate the rotation and disassembly of the enclosed protective cap 2 using tools. The bottom end face of the regular hexagonal prism of the enclosed protective cap 2 is provided with a threaded blind hole to facilitate the threaded installation of the enclosed protective cap 2 on the prestressed anchor bolt 3. The threaded blind hole of the enclosed protective cap 2 is used to install the vertically enclosed prestressed anchor bolt 3 to facilitate the wind turbine structure... The structure is stably installed on the wind turbine foundation by prestressed anchor bolts 3. The top end face of the prestressed anchor bolt 3 is provided with a threaded rod, which facilitates the installation of the protective cap 2 and the wind turbine plate pressure cylinder 5 by thread. The top end face of the threaded rod of the prestressed anchor bolt 3 is provided with a frustum, which reduces the difficulty of alignment with the protective cap 2 and the wind turbine plate pressure cylinder 5. The outer circumference of the prestressed anchor bolt 3 is fitted with an anchor bolt protection tube 4 in the vertical direction, which facilitates the protection of the pre-embedded part of the prestressed anchor bolt 3. The surface of the anchor bolt protection tube 4 is provided with a corrosion-resistant layer, which helps to increase the service life of the anchor bolt protection tube 4. The ends of the anchor bolt protection tube 4 are chamfered, which facilitates the quick alignment and insertion of the prestressed anchor bolt 3.
[0029] The prestressed anchor bolt 3 has a wind turbine plate pressure cylinder 5 installed on its upper threaded rod, which facilitates pressing the wind turbine structure cylinder onto the wind turbine foundation. The wind turbine plate pressure cylinder 5 has threads on its inner circumference, allowing it to be threaded onto the threaded rod of the prestressed anchor bolt 3. The outer circumference of the wind turbine plate pressure cylinder 5 has a regular hexagonal structure, facilitating its rotation and disassembly using tools. A vertical indicator groove is located on the front of the outer circumference of the wind turbine plate pressure cylinder 5, ensuring alignment with the indicator groove of the wind turbine structure plate 7 for locking. An elastic anti-loosening ring 6 is fitted in the middle of the threaded rod of the prestressed anchor bolt 3, allowing for tightening and preventing loosening of the wind turbine plate pressure cylinder 5 through applied force. The elastic anti-loosening ring 6 is integrally formed... The spiral open ring plate structure facilitates the elastic deformation of the elastic anti-loosening ring 6 under stress. The surface of the elastic anti-loosening ring 6 is provided with a corrosion-resistant layer to increase its service life. The lower part of the threaded rod of the prestressed anchor bolt 3 is fitted with a fan structure plate 7 to facilitate the determination of whether the fan plate pressure cylinder 5 has become loose. The fan structure plate 7 has a through-hole in the middle to facilitate the passage of the prestressed anchor bolt 3. A waterproof cylinder is provided on the outer periphery of the top end face of the fixing hole of the fan structure plate 7 to facilitate the fit with the closed protective cap 2 and prevent rainwater from entering the inside of the waterproof cylinder. A front-back indicator groove is provided on the front end face of the top end face of the waterproof cylinder of the fan structure plate 7 to facilitate the determination of the locking status of the fan plate pressure cylinder 5.
[0030] The specific usage and function of this embodiment are as follows:
[0031] In this utility model, such as Figure 1 As shown, the wind turbine structure plate 7 is a cut-off section of the wind turbine structure tube. The front, rear, left, and right ends of the wind turbine structure plate 7 are all cut-off surfaces. The lower ends of the prestressed anchor bolts 3 and anchor bolt protective pipes 4 are cut off, and the cut-off portions are embedded inside the wind turbine foundation, thus stabilizing and reinforcing the foundation. Simultaneously, the chamfered design of the ends of the anchor bolt protective pipes 4 ensures precise alignment of the prestressed anchor bolts 3. The corrosion-resistant layer of the anchor bolt protective pipes 4 resists underground environmental erosion. Furthermore, there is a 10mm gap between the top end face of the anchor bolt protective pipes 4 and the bottom end face of the wind turbine structure plate 7, thus preventing rainwater from entering the anchor bolt protective pipes 4. The flared opening of the sealed protective cap 2 and the waterproof sleeve of the wind turbine structure plate 7 are nested together, as shown in the diagram. Figure 2 As shown, this prevents rainwater from entering the waterproof cylinder of the fan structure plate 7, thus protecting the mating parts of the anchor bolts and nuts. At the same time, whether the indicator grooves of the fan plate pressure cylinder 5 and the fan structure plate 7 are aligned is the key to determining whether the fan plate pressure cylinder 5 is locked. If the indicator grooves are aligned, the fan plate pressure cylinder 5 is in a locked state; if the indicator grooves are misaligned, the fan plate pressure cylinder 5 is in a loose state. Meanwhile, the protective cap 2 is made of transparent material, which makes it easy to observe the alignment status of the indicator grooves of the internal fan plate pressure cylinder 5 and the fan structure plate 7.
[0032] Example 2:
[0033] The difference from Embodiment 1 is that the regular hexagonal prism of the closed protective cap 2 can also be set as a regular heptagonal prism, which makes the closed protective cap 2 require a special tool that works with the regular heptagonal prism to rotate, thus preventing non-workers from rotating and disassembling the closed protective cap 2.
[0034] Example 3:
[0035] The difference from Embodiment 1 is that the regular hexagonal structure of the fan plate pressure cylinder 5 can also be set as a regular heptagonal structure, which makes the fan plate pressure cylinder 5 require a special tool that works with the regular heptagonal structure to rotate, thus preventing non-staff members from rotating and disassembling the fan plate pressure cylinder 5.
