Description

Technical Field

[0001] This utility model relates to the field of building construction accessories, and in particular to a protective device for wind power foundation anchor bolts. Background Technology

[0002] With the rapid development of the wind power industry, the construction of wind turbine foundations determines the safety and stability of wind turbine operation. Currently, most wind turbine foundations utilize prestressed anchor bolt assemblies, which run the entire foundation. Compared to traditional foundation rings, these assemblies offer several advantages: superior overall performance, no weak points, guaranteed rigid connection between the tower and foundation, reduced reinforcement and construction work, and improved overall safety. The anchor bolts in the prestressed anchor bolt assembly are isolated from the foundation concrete by PE protective sleeves and heat-shrink sleeves at both ends to facilitate subsequent prestressing construction. However, during current construction, since wind turbine foundations are mostly circular and the main reinforcement bars are radial bars, these need to be inserted into the gaps between the anchor bolts. During construction, the heads of these radial bars are highly susceptible to colliding with the protective sleeves of the anchor bolts on the outer ring of the foundation, leading to sleeve damage. Utility Model Content

[0003] The purpose of this utility model is to provide a protective device for wind power foundation anchor bolts, which solves the problem that the anchor bolt protective sleeve is easily damaged during the construction process of the existing technology.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: two or more sleeves adapted to the anchor rod, the sleeves are connected to fixing members at intervals, the fixing members are fixing plates or springs, the sleeves are provided with openings, the sleeves are provided with cavities, the cavities are connected to the openings, and the sleeves are provided with locking devices, the locking devices include: clamps provided on the sleeves, adhesive tape provided on the sleeves, or hooks provided on the springs.

[0005] The sheath has a C-shaped horizontal cross-section.

[0006] The clamp includes: a retaining ring hinged to the sheath, a locking bolt hinged to the movable end of the retaining ring, a retaining ring having a groove plate that mates with the locking bolt, a locking nut being movably connected to the locking bolt, and a protective pad on the inner side of the retaining ring.

[0007] The clamp includes: a fixed ring connected to the outside of the sheath, a retaining ring hinged to the fixed ring, a locking bolt hinged to the movable end of the retaining ring, a retaining ring having a groove plate that mates with the locking bolt, a locking nut being movably connected to the locking bolt, and a protective pad on the inner side of the retaining ring.

[0008] The adhesive tape includes: a tape body, with Velcro at both ends of the tape body.

[0009] The fixing plate is an arc-shaped plate and is connected to the outside of the sheath.

[0010] When the fixing component is a fixing plate, one end of the fixing plate is provided with a slot and the other end of the fixing plate is provided with a tenon.

[0011] When the fixing component is a spring, hooks are provided at the beginning and end of the spring, respectively.

[0012] The outer wall of the sheath is provided with a protective pad.

[0013] The sheath and fasteners are protective components, and two or more protective components are inserted end to end to form a ring that fits with the foundation.

[0014] The sheath and fasteners are protective components, and two or more protective components are hooked together end to end to form a ring that cooperates with the foundation.

[0015] This invention employs a protective sleeve, fasteners, and a locking device, which facilitates operator work and ensures that the radial reinforcement head only impacts the protective sleeve during installation, protecting the anchor rod protective sleeve within its cavity from damage and ensuring the quality of anchor bolt construction. Secondly, the locking device facilitates the installation and removal of the protective sleeve on the anchor rod, effectively improving construction efficiency. Thirdly, by setting a protective pad on the outer wall of the protective sleeve, a cushioning effect is provided, further extending the service life of the protective sleeve. Attached Figure Description

[0016] Figure 1 This is a front view of Embodiment 1 of the present invention. Figure 2 for Figure 1 Top view. Detailed Implementation

[0017] like Figure 1 and Figure 2 The first embodiment of this utility model, as shown, includes: five protective sleeves 1 adapted to the anchor bolt, with fixing members 2 spaced apart from each other. The fixing members 2 are fixing plates, which are arc-shaped plates connected to the outside of the protective sleeves. Each protective sleeve 1 has an opening and an internal cavity 3 connected to the opening. The horizontal cross-section of the protective sleeve 1 is C-shaped. Each protective sleeve 1 has a locking device, which is a clamp on the protective sleeve. The clamp includes: a retaining ring 4 hinged to the protective sleeve, with a locking bolt 5 hinged to the movable end of the retaining ring 4. The protective sleeve 1 has a slotted plate 6 that mates with the locking bolt, and the slotted plate 6 has a groove 10 for the locking bolt to be inserted. A locking nut 7 is movably connected to the locking bolt 5. A protective pad, made of silicone, is provided inside the retaining ring 4 to prevent the clamp from damaging the anchor bolt protective sleeve when fixing the protective sleeve. When the clamp is locked, after the retaining ring 4 and the protective sleeve 1 are aligned, the locking bolt 5 is inserted into the groove 10 on the groove plate 6, and then the locking nut 7 is turned to tighten the retaining ring and the groove plate to complete the locking.

[0018] One end of the fixing plate has a slot 8, and the other end of the fixing plate has a tenon 9. The sheath and the fixing component are protective components. The tenons 9 and slots 8 at the ends of two or more protective components are inserted to form a ring that cooperates with the foundation, thus forming a protective sleeve for the entire foundation anchor bolt.

[0019] As an improvement to this embodiment, the locking device may also employ the following types of clamps or adhesive tape. The clamp includes: a fixing ring connected to the outside of the sheath, the fixing ring being hinged to a retaining ring, the movable end of the retaining ring being hinged to a locking bolt, the sheath having a groove plate that mates with the locking bolt, a locking nut being movably connected to the locking bolt, and a protective pad on the inner side of the retaining ring. The adhesive tape includes: a tape body, with Velcro straps at both ends.

[0020] Embodiment two of this utility model includes: five sheaths adapted to anchor bolts, with fixed members (springs) spaced apart from each other. Each sheath has an opening and an internal cavity communicating with the opening. The horizontal cross-section of the sheath is C-shaped. Each sheath is equipped with a locking device, consisting of hooks at the beginning and end of the springs. The sheaths and fixed members form a protective assembly. Two or more protective assemblies are hooked together end-to-end to form a ring that fits with the foundation. The tension of the springs secures the sheaths to the outside of the anchor bolts, thus protecting the anchor bolts within their cavities.

[0021] During construction, the anchor rod and its protective sleeve are first inserted into the cavity through the opening on the sleeve. Then, the protective component is fixed to the anchor rod by a locking device, thereby preventing damage to the anchor rod and protective sleeve by the radial steel bars during construction.

[0022] The embodiments described above merely illustrate several implementations of this utility model, and should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
