[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figure 1-5A safety railing for a wind turbine base includes a wind turbine base 1 and several railing surfaces 2. The upper end of the wind turbine base 1 has a circular slot 3. Several circular slots 4 are located on the bottom of the wind turbine base 1 near the annular inner wall of the circular slot 3. These circular slots 4 are evenly spaced and arranged in a ring. Each circular slot 4 has a positioning mechanism, and each positioning mechanism has several supporting columns 5. The positioning mechanism includes a threaded post 6 located at the bottom of the circular slot 4. A circular post 7 is inserted into the circular slot 4. The lower end of the circular post 7 has a first threaded hole 8, and the threaded post 6 is threadedly connected to the first threaded hole 8. A rotating rectangular positioning block 9 causes the threaded post 6 in the circular slot 4 to be threadedly connected to the first threaded hole 8 on the circular post 7, effectively locking the rectangular positioning block 9 and the circular post 7 into the circular slot 4. The upper end of the circular post 7 has a rectangular positioning block 9, and the lower end of the supporting column 5 has a rectangular slot 10. The rectangular positioning block 9 is inserted into the rectangular slot 10. The inner walls on both the left and right sides of the center position are provided with first through holes 11. The side wall of the rectangular positioning block 9 facing the first through hole 11 is provided with a second through hole 12 that is connected to the left and right sides. The same double-ended bolt 13 is inserted between the two first through holes 11 and the second through hole 12. Nuts 14 are threaded onto both ends of the double-ended bolt 13. Several rectangular positioning blocks 9 are respectively inserted into the rectangular slots 10 on several supporting columns 5, so that the first through holes 11 on the rectangular slots 10 are connected to the second through holes 12 on the rectangular positioning blocks 9. The double-ended bolt 13 is inserted through and connected to the first through holes 11 and the second through holes 12. Nuts 14 are tightened at both ends of the double-ended bolt 13 for fixation, which replaces welding fixation. It is convenient to disassemble and replace after damage, reducing maintenance costs. The circular column 7 and the rectangular positioning block 9 are integrally cast. The threaded column 6 is welded and fixed to the bottom of the circular slot 4. Several circular columns 7 on several rectangular positioning blocks 9 are respectively inserted into several circular slots 4 on the bottom of the circular slot 3.
[0024] The wind turbine base 1, guardrail surface 2, and support column 5 are all sheet metal parts. Several guardrail surfaces 2 are respectively set between two adjacent support columns 5. Rectangular slots 15 are provided on the upper left and right sides of the center of several support columns 5. Several guardrail surfaces 2 are respectively inserted into two adjacent rectangular slots 15. Rectangular openings 16 are provided at the upper end of several support columns 5. The rectangular openings 16 are connected to the rectangular slots 15 on both sides. Rectangular pressure plates 17 are inserted into the rectangular openings 16. The left and right ends of the rectangular pressure plates 17 are respectively inserted into two rectangular slots 15. The lower end of the rectangular pressure plates 17 abuts and presses against the upper end of the guardrail surface 2. A circular opening 18 is provided at the upper end of the center of the rectangular pressure plate 17. The rectangular opening 16 is directly... A second threaded hole 19 is provided on the bottom of the circular opening 18. A fixing bolt 20 is inserted through the circular opening 18 and threadedly connected to the second threaded hole 19. The bottom of the rectangular opening 16 is on the same horizontal plane as the top of the guardrail surface 2. The rectangular pressure plate 17 is made of corrosion-resistant alloy steel. Several guardrail surfaces 2 are respectively inserted into the rectangular slots 15 on two adjacent support columns 5. The rectangular pressure plate 17 is inserted into the rectangular opening 16 at the top of the support column 5. The fixing bolt 20 is screwed into the second threaded hole 19 after passing through the circular opening 18, so that the rectangular pressure plate 17 presses and positions the guardrail surface 2 in the rectangular slot 15, which facilitates quick installation, positioning, or replacement and maintenance of the guardrail surface 2.
[0025] In use, the circular posts 7 on several rectangular positioning blocks 9 are respectively inserted into several circular slots 4 at the bottom of the circular slots 3. The rectangular positioning blocks 9 are rotated so that the threaded posts 6 in the circular slots 4 are threadedly connected to the first threaded holes 8 on the circular posts 7. Then, the several rectangular positioning blocks 9 are respectively inserted into the rectangular slots 10 on several supporting columns 5, so that the first through holes 11 on the rectangular slots 10 are aligned with the second through holes 12 on the rectangular positioning blocks 9. The double-ended bolts 13 are then inserted through the aligned first through holes 11 and second through holes 12. The guardrail is fixed by tightening nuts 14 at both ends of the double-headed bolt 13, replacing welding. This makes it easier to disassemble and replace if damaged, reducing maintenance costs. Several guardrail panels 2 are inserted into rectangular slots 15 on two adjacent support columns 5. A rectangular pressure plate 17 is inserted into a rectangular opening 16 at the upper end of the support column 5. The fixing bolt 20 is screwed into the second threaded hole 19 after passing through the circular opening 18. This makes the rectangular pressure plate 17 press and position the guardrail panel 2 in the rectangular slot 15, which facilitates quick installation, positioning, or replacement and maintenance of the guardrail panel 2.
