Description

Technical Field

[0001] This utility model relates to the field of building installation, and in particular to a protective device for the inner wall of a cable conduit for a wind turbine foundation. Background Technology

[0002] Currently, the installed capacity of new energy wind power generation units is getting larger and larger, the design precision requirements of wind turbines are getting higher and higher, while the overall price of wind turbines is getting lower and lower. Under the condition of meeting the design and use of wind turbines, the selection of materials is becoming more and more economical. Most manufacturers use PVC pipes as pre-embedded cable conduits for wind turbine foundations. The conduits need to be tied to the wind turbine foundation reinforcement in advance. In order to prevent the conduit from shifting in the stress position during the pouring process, workers usually increase the binding force when tying, which causes uneven stress on the cable conduit binding position during the pouring process, resulting in local deformation. This causes blockage during the cable installation process, requiring internal grinding, rework and repair, etc., affecting the construction progress and the quality of concealed works. Summary of the Invention

[0003] This utility model aims to address the shortcomings of existing technologies by providing a protective device for the inner wall of a wind turbine foundation cable conduit.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a wind turbine foundation cable sleeve inner wall protection device, including an arc-shaped inner support plate and a double-ended bolt. A threaded sleeve is provided at the center of the opposite surface of a pair of arc-shaped inner support plates. The two ends of the double-ended bolt are respectively threaded into the two threaded sleeves, and a nut is fixed in the middle of the outer wall of the double-ended bolt. The spacing between the pair of arc-shaped inner support plates can be adjusted by rotating the nut with a wrench.

[0005] Specifically, several diagonal braces are provided between the threaded sleeve and the arc-shaped inner support plate.

[0006] Specifically, the nut is a twelve-cornered nut.

[0007] In particular, the contact surfaces of the arc-shaped inner support plate and the cable sleeve are equipped with anti-slip buffer pads.

[0008] In particular, the corners of the arc-shaped inner support plate, the threaded sleeve, and the nut are all rounded.

[0009] The beneficial effects of this utility model are as follows: By setting an arc-shaped inner support plate, double-headed bolts, threaded sleeves, and nuts, this utility model is convenient for on-site installation and disassembly. It is suitable for reinforcing the stress position of cable sleeves before installation of all types of wind turbine foundations. It effectively solves the problem of local deformation caused by uneven stress during the binding and concrete pouring process of cable sleeves, avoids subsequent maintenance and rework, saves manpower working time, and increases the accuracy and aesthetics of cable sleeve installation process, thereby increasing the pass rate of concealed works quality acceptance.

[0013] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0015] like Figures 1-2 As shown, a protective device for the inner wall of a wind turbine foundation cable conduit includes an arc-shaped inner support plate 1 and a double-ended bolt 2. A threaded sleeve 3 is provided at the center of the opposite surfaces of the pair of arc-shaped inner support plates 1. The two ends of the double-ended bolt 2 are threaded into the two threaded sleeves 3 respectively, and a nut 4 (dodecagonal nut) is fixed in the middle of the outer wall of the double-ended bolt 2. The spacing between the pair of arc-shaped inner support plates 1 can be adjusted by rotating the nut 4 with a wrench. The arc-shaped inner support plates 1 are matched with the inner wall dimensions of the cable conduit. By adjusting the double-ended bolt 2, the two arc-shaped inner support plates 1 are tightened to support the cable conduit, effectively reducing the deformation of the cable conduit caused by binding and concrete pouring vibration.

[0016] Several diagonal braces 5 are provided between the threaded sleeve 3 and the arc-shaped inner support plate 1. The diagonal braces 5 can enhance the support stability. When setting them, the inclination angle of the diagonal braces 5 can be adjusted according to the number of cables installed to avoid occupying too much space.

[0017] The contact surface between the arc-shaped inner support plate 1 and the cable sleeve is provided with an anti-slip buffer pad to provide a certain buffering effect and prevent the arc-shaped inner support plate 1 from sliding inside the cable sleeve.

[0018] The corners of the arc-shaped inner support plate 1, the threaded sleeve 3, and the nut 4 are all rounded to avoid damage to the cable surface during cable installation.

[0019] In operation, this invention first connects two arc-shaped inner support plates 1 to double-ended bolts 2, adjusting the length of the double-ended bolts 2 extending into the threaded sleeve 3 so that the arc-shaped inner support plates 1 are basically in contact with the inner wall of the cable sleeve. Then, the arc-shaped inner support plates 1 are moved to the position of the cable sleeve requiring reinforcement using a tightening wrench. The nut 4 is then turned with the tightening wrench to tighten the arc-shaped inner support plates 1 and support the cable sleeve, ensuring that there is no deformation at the stress position of the cable sleeve. By installing this device at the easily deformable position on the inner wall of the cable sleeve, internal protection is strengthened, effectively solving the problem of local deformation of the cable sleeve caused by uneven stress during the binding and concrete pouring process. This avoids subsequent maintenance and rework, saves manpower time, and increases the accuracy and aesthetics of the cable sleeve installation process, thereby increasing the pass rate of concealed works quality acceptance.
