[0021] A symmetrically distributed clamping block 22 is fixedly installed at one end of the fixed block 19, and a fixed column 23 is fixedly installed at the opposite end of the clamping block 22. A rotating ring 24 is rotatably sleeved on the outer side of the fixed column 23. One end of the rotating ring 24 is fixedly connected to the lifting block 20. A support rod 25 is fixedly installed at the bottom end of the lifting block 20, and one end of the support rod 25 is in contact with one end of the fixed block 19.
[0022] By adopting the above technical solution, the rotating ring 24 rotates on the fixed column 23, thereby driving the lifting block 20 to rotate. When the lifting block 20 moves upward to turn the switch 32 off, the lifting block 20 is supported by the supporting rod 25 to facilitate closing the switch 32. When the lifting block 20 moves downward to reset, the lifting block 20 and the switch 32 are in contact and the rotating ring 24 rotates on the fixed column 23, so that the lifting block 20 can be reset. The structure is ingenious and practical.
[0023] A symmetrically distributed L-shaped plate 26 is movably mounted on the outer side of the base 1 , and a symmetrically distributed handle 27 is fixedly mounted on one end of the L-shaped plate 26 .
[0024] By adopting the above technical solution, the base 1 can be easily carried and moved by providing the handle 27 .
[0025] One end of the L-shaped plate 26 is threadedly mounted with symmetrically distributed bolts 28 , and one end of the bolts 28 is threadedly penetrates the L-shaped plate 26 and is threadedly mounted inside the base 1 .

[0031] Working principle: First, start the waste heat power generation steam turbine body 2 to operate. When the waste heat power generation steam turbine body 2 has a problem with overload operation, the overload information is transmitted to the second transmission chip 15 through the action of the first transmission chip 12 in the fixed box 11. The second transmission chip 15 then transmits the information to the control panel 14. The control panel 14 then controls the motor 21 to start. The motor 21 drives the screw 17 to rotate. The rotation of the screw 17 drives the moving cylinder 18 to move upward. The T-shaped block 30 slides in the slide groove 29 to guide the moving cylinder 18. The movement of the moving cylinder 18 drives the fixed block 19 to move. The fixed block 19 drives the block 22, the fixed column 23, the rotating ring 24 and the lifting block 20 to move. The lifting block 20 moves and contacts the switch 32. Then the switch 32 is pushed to close, thereby realizing a protective measure for the waste heat power generation turbine body 2, preventing the waste heat power generation turbine body 2 from being forced to operate without being closed, causing more serious damage to internal parts, thereby improving the safety of use of the waste heat power generation turbine body 2 and also increasing its service life. The rotating ring 24 rotates on the fixed column 23, thereby rotating the rotating ring 24 and driving the lifting block 20 to rotate. Then, when the lifting block 20 moves upward to bend the switch 32 to close, the lifting block 20 is supported by the push rod 25 to facilitate closing the switch 32. When the lifting block 20 moves downward to reset, the lifting block 20 and the switch 32 are in contact and rely on the rotating ring 24 to rotate on the fixed column 23, so that the lifting block 20 can be reset. The structure is ingenious and practical.
