It is convenient for power peak regulation and is conducive to improving resource utilization and the comprehensive benefits of the economy and society. Under the increasingly tight traditional energy situation on the earth, countries around the world generally give priority to the development of hydropower and vigorously utilize water resources.

This arrangement allows the transmission rods 708 on both sides to rotate through the toothed sleeve 711.

[0035] Working process: Before use, the present invention is powered by an external power supply, and the winch 2 is started so that the winch 2 can reel in and unwind the wire rope 3. The outer frame 1 is moved so that the inner frame 4 is set above the pipe to be fixed. Then the wire rope 3 is unwound so that the inner frame 4 reaches the outside of the pipe. Then the first motor 502 is started so that the first motor 502 drives the first screw 503 to rotate. The first screw 503 is screwed into engagement with the thread of the push plate 504, driving the push plate 504 to slide on the inner side of the fixed seat 501. After sliding, the push plate 504 drives the lower clamping arc plate 5 07 approaches the pipeline and lifts the pipeline upward, so that the lower clamping arc plate 507 clamps the pipeline, thereby fixing the pipeline on the inner side of the inner frame 4. Then, the second screw 601 is rotated, so that the second screw 601 drives the upper clamping arc plate 602 to move downward on the inner side of the inner frame 4 until the upper clamping arc plate 602 contacts the top of the pipeline, thereby fixing the top of the pipeline. The second motor 607 is started to drive the first transmission wheel 608 to rotate. After the first transmission wheel 608 rotates, it drives the gear ring 606 to rotate by engaging with the gear ring 606. The gear ring 606 After the rotation, the sliding plate 603 will be driven to slide by engaging with the tooth groove 605, and the sliding directions of the sliding plates 603 on the left and right sides are opposite. After sliding, the sliding plate 603 will drive the upper clamping arc plate 602 to rotate through the telescopic connecting rod 604, so that the upper clamping arc plate 602 can adjust the position of the pipe joint in the left and right directions, which is convenient for the connection between different pipes. The winch 2 can wind up the wire rope 3, which can drive the inner frame 4 to move upward to adjust the fixed height of the pipe. When the inner frame 4 is raised or lowered, the third motor 705 can be started to drive the third screw As the rod 703 rotates, the third screw 703 screws into engagement with the thread of the sliding support post 702, driving the sliding support post 702 to slide out from the inner side of the sliding guide rail 701, so that the sliding support post 702 contacts the inner wall surface of the outer frame 1, thereby fixing the position of the inner frame 4. The first bevel gear 704 is engaged with the second bevel gear 706, so that the transmission rod 708 rotates at the same time during the rotation of the third screw 703. The toothed sleeve 711 is engaged with the second transmission gear 709, so that the transmission rods 708 on the upper and lower sides rotate at the same time, thereby realizing the simultaneous sliding of the sliding support posts 702 on the upper and lower sides.

[0036] Example 2:

[0037] See also Figure 1-6 , the present invention provides a technical solution:

[0038] A fixing device for buried pipes of water conservancy and hydropower. The parts of Example 2 that are the same as those in Example 1 are not repeated in the present invention. The difference lies in the work flow.

[0039] Working process: During use of the present invention, the electric telescopic rod 712 can be extended to drive the perforated plate 710 to move. After the perforated plate 710 moves, it will drive the toothed sleeve 711 to slide until the toothed sleeve 711 no longer meshes with the second transmission gear 709. At this time, the transmission rods 708 on the upper and lower sides will not drive the perforated plate 710 to rotate through the second transmission gear 709 after rotation, so that the transmission rods 708 on the upper and lower sides can rotate asynchronously. The third motor 705 drives the third screw 703 to rotate, so that the sliding support post 702 slides out from the inner side of the sliding guide rail 701. Different sliding distances are adjusted for the sliding support posts 702 at different positions. After the sliding support posts 702 are in contact with the inner wall surface of the outer frame 1, the angle of the inner frame 4 is adjusted under the support of the sliding guide rail 701 and the sliding support posts 702 on the inner frame 4, so that the rotation of the inner frame 4 is achieved, which facilitates the adjustment of the lowering angle of the inner frame 4 when the pipeline is lowered.
