[0024] The embodiment of the utility model discloses a prestressed pipe installation structure for a wind turbine generator set foundation.

[0025] The utility model provides Figures 1-4The shown structure is a prestressed pipe installation structure for the foundation of a wind turbine generator set, including a mounting tube 1 and two mounting plates 2. A first mounting groove 3 is provided on the tube walls at both ends of the mounting tube 1. A mounting ring 4 is fixedly connected to the surface of the mounting tube 1. Two clamping grooves 5 are symmetrically provided inside the mounting ring 4. A clamping ring 6 is fixedly connected to the side wall of each mounting plate 2. A clamping mechanism is provided on one end side wall of each clamping ring 6. One end of each clamping ring 6 is clamped with the corresponding clamping groove 5 through the clamping mechanism. A second mounting groove 7 is provided on the side wall of each mounting plate 2 corresponding to the first mounting groove 3. The two ends of the mounting tube 1 are respectively clamped with a first prestressed corrugated pipe 8 and a second prestressed corrugated pipe 9 through the first mounting groove 3 and the second mounting groove 7. The insides of the first mounting groove 3 and the second mounting groove 7 are fixedly connected to the rubber sealing gasket 17.

[0026] By setting up a mounting tube 1 and two mounting plates 2, the first prestressed bellows 8 and the second prestressed bellows 9 are sleeved on both ends of the mounting tube 1 through the first mounting groove 3, and then the second mounting grooves 7 on the two mounting plates 2 correspond to the first mounting grooves 3 and the two mounting plates 2 are clamped and connected to the mounting tube 1 through a clamping mechanism, so that the first prestressed bellows 8 and the second prestressed bellows 9 are clamped between the first mounting groove 3 and the second mounting groove 7. Finally, the rubber sealing gasket 17 is used to make the first prestressed bellows 8 and the second prestressed bellows 9 more tightly connected to the mounting tube 1, which is convenient for workers to install the prestressed bellows, avoids damage to the prestressed bellows during installation, and improves its durability and crack resistance.

[0027] In order to improve the work quality and efficiency of workers when installing prestressed corrugated pipes, such as Figures 1-4 As shown, the clamping mechanism includes a slide rail 10, two sliders 11, two arc-shaped clamping blocks 12 and multiple springs 13. The side wall of the slide rail 10 is fixedly connected to the side wall of the clamping ring 6, one end side wall of each slider 11 is slidably connected to the inside of the slide rail 10, each arc-shaped clamping block 12 is fixedly connected to the other end side wall of the corresponding slider 11, and the two ends of each spring 13 are respectively fixedly connected to the side walls of the two corresponding arc-shaped clamping blocks 12.
