[0034] Specifically, this invention changes the connection method between the connecting ring 1 and the axial compressor. First, the connecting ring 1 abuts against the axial compressor casing. Then, the arc-shaped strips 4 and 5 are moved to abut against the outer wall of the axial compressor casing. Finally, the fixing bolt 13 is threaded into the threaded holes 11 and 12, thus completing the connection between the main structure and the axial compressor. When disassembling the connecting ring 1 and the axial compressor, the fixing bolt 13 is removed from the threaded holes 11 and 12. Then, the arc-shaped strips 4 and 5 are moved to abut against the axial compressor casing, allowing for disassembly of the connecting ring 1 and the axial compressor. Therefore, this invention is relatively simple and convenient for disassembling the main structure and the axial compressor, and also facilitates the maintenance of the internal components of the main structure.

[0035] Furthermore, by providing the flow guide 25, the flow path of the wind can be guided and limited under the action of the flow guide 25, so as to avoid uneven flow of wind or mutual obstruction inside the cone shroud 2, thereby improving the jet effect of the main structure.

[0036] Furthermore, by incorporating a sealing strip 8, the sealing performance at the connection between the arc-shaped strip 4, the arc-shaped strip 5, and the axial compressor casing can be improved, preventing leakage and enhancing the jetting effect of the main structure.

[0037] Example 2

[0038] Please see Figure 1 , 3 The present invention provides a technical solution: a self-circulating jet structure for a compressor that utilizes the pressure difference in the end region. A connecting groove 14 is provided on the outer wall of the connecting ring 1. A connecting strip 15 is fixed to one end of the conical cover 2 near the connecting ring 1. The connecting strip 15 is located inside the connecting groove 14. A threaded hole 3 16 is provided at the top of the connecting strip 15. A threaded hole 4 is provided at the bottom of the connecting groove 14. A fixing bolt 2 17 is threadedly connected inside the threaded hole 3 16 and the threaded hole 4.

[0039] Specifically, when disassembling the connecting ring 1 and the conical cover 2, after removing the fixing bolt 2 17 from the threaded hole 3 16 and thread 4, the connecting ring 1 and the conical cover 2 can be disassembled, which facilitates the maintenance of the internal components of the connecting ring 1 and the conical cover 2.

[0041] Please see Figure 4 , 5The application provides a technical scheme: a self-circulation jet structure of a compressor using an end area pressure difference, an annular sliding groove 18 is formed in the inner wall of a conical cover 2, and a sliding block 19 is installed in the annular sliding groove 18; one end of the sliding block 19 is fixed with a rotating ring 20; the inner wall of the rotating ring 20 is fixed with a rotating block 21, and one end of the rotating block 21 is provided with an inclined groove 22; one side of the inner wall of the inclined groove 22 is rotatably connected with a gas collecting wheel 23, and one end of the gas collecting wheel 23 is fixed with a jet block 24.

[0042] Specifically, the inclined groove 22 is formed in the rotating block 21, when the wind blows to the rotating block 21, the rotating ring 20 is rotated under the action of the wind force, and the jet block 24 and the gas collecting wheel 23 are rotated when the rotating ring 20 rotates, thereby improving the air outlet efficiency of the air outlet of the conical cover 2 and further improving the jet effect of the structure body.

[0043] Working principle:

[0044] Firstly, the connecting mode of the connecting ring 1 and the axial flow compressor is changed, specifically, firstly, the connecting ring 1 is abutted with the axial flow compressor casing, then the arc-shaped strip one 4 and the arc-shaped strip two 5 are moved respectively, so that the arc-shaped strip one 4 and the arc-shaped strip two 5 are abutted with the outer wall of the axial flow compressor casing, then the fixed bolt one 13 is screw-connected into the inside of the threaded hole one 11 and the threaded hole two 12, so that the connection of the structure body and the axial flow compressor is completed, when the connecting ring 1 and the axial flow compressor are disassembled, the fixed bolt one 13 is taken out from the inside of the threaded hole one 11 and the threaded hole two 12, then the arc-shaped strip one 4 and the arc-shaped strip two 5 are moved so that the arc-shaped strip one 4 and the arc-shaped strip two 5 are not abutted with the axial flow compressor casing, so that the connecting ring 1 and the axial flow compressor are disassembled, so that the structure body and the axial flow compressor are disassembled, and the maintenance of the parts in the structure body is facilitated.
