DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] As a specific embodiment of the present invention, Figures 1 to 3 As shown, an efficiency-increasing and emission-reducing device for a gas turbine in an IGCC power plant comprises an efficiency-increasing and emission-reducing device body 1, a cover plate 2, a clamping block 3, a mounting block 4 and a clamping slot 5. The cover plate 2 is arranged on the front side of the efficiency-increasing and emission-reducing device body 1, the clamping block 3 is fixedly connected to the cover plate 2 on one side close to the cover plate 2, the mounting block 4 is fixedly connected to the efficiency-increasing and emission-reducing device body 1 on one side close to the efficiency-increasing and emission-reducing device body 1, the clamping slot 5 is arranged on the front side of the mounting block 4, the rear side of the clamping block 3 cooperates with the clamping slot 5, the inner cavity of the mounting block 4 is arranged with a accommodating cavity 6, the inner cavity of the accommodating cavity 6 is arranged with a clamping block fixing mechanism 7 used in cooperation with the mounting block 4, and the side of the clamping block 3 close to the clamping block fixing mechanism 7 is arranged with a fixing slot 8 used in cooperation with the clamping block fixing mechanism 7.

[0032] Specifically, refer to Figure 3 The card block fixing mechanism 7 includes a fixing block 701, and a push block 702 is arranged on the front and rear sides of the fixing block 701. A pinch rod 703 is fixedly connected to the bottom of the push block 702, and a side of the fixing block 701 close to the fixing groove 8 cooperates with the fixing groove 8 for use.

[0033] By adopting the above solution, by setting the clamping block fixing mechanism 7, the fixing block 701 can be used in conjunction with the fixing block 701 to better fix the fixing groove 8, so that the fixing block 701 can be better positioned and clamped.

[0034] As a preferred embodiment, refer to Figure 3 A slide groove 9 is provided on the inner wall of the accommodating cavity 6 , and a slide rod 10 is provided in the inner cavity of the slide groove 9 , and the top of the slide rod 10 is fixedly connected to the pinch rod 703 .

[0035] The above solution is adopted: by providing the slide groove 9 and the slide rod 10, the slide groove 9 and the slide rod 10 can be used in cooperation to prevent the pinching rod 703 from being offset during the movement, so that the pinching rod 703 can be moved better.

[0036] As a preferred embodiment, refer to Figure 3 A limiting groove 11 is provided on the right side of the fixing block 701 , and a limiting rod 12 is provided in the inner cavity of the limiting groove 11 . The side of the limiting rod 12 away from the limiting groove 11 is fixedly connected to the inner wall of the accommodating cavity 6 .

[0037] The above solution is adopted: by providing the limiting groove 11 and the limiting rod 12, the limiting groove 11 and the limiting rod 12 can be used in coordination to allow the fixing block 701 to move better, which is convenient for users.

[0038] As a preferred embodiment, refer to Figure 3 The inner wall of the limiting groove 11 is fixedly connected with a first elastic member 13, and the right side of the first elastic member 13 is fixedly connected with the limiting rod 12. In this embodiment, the first elastic member 13 is a spring.

[0039] By adopting the above solution, the first elastic member 13 is provided, and the fixing block 701 can be automatically reset after being moved through the cooperation of the first elastic member 13, so that the user can use it better.

[0040] As a preferred embodiment, refer to Figure 3 The inner wall of the accommodating cavity 6 is fixedly connected with a second elastic member 14, and opposite sides of the two second elastic members 14 are fixedly connected to the push block 702. In this embodiment, the second elastic member 14 is a tension spring.

[0041] With the above solution, by providing the second elastic member 14, the second elastic member 14 can be used together to allow the push block 702 to drive the pinch rod 703 to reset better after the push block 702 has moved.

[0042] The working principle of the present invention is as follows:

[0043] When in use, the pinching rod 703 is pinched to make the two pinching rods 703 approach each other. As the pinching rod 703 moves, the pinching rod 703 will also drive the pushing block 702 to move, so that the pushing block 702 pulls the second elastic member 14 to make the second elastic member 14 be stressed. As the pushing block 702 moves, the pushing block 702 will squeeze the fixing block 701 to make the fixing block 701 move. As the fixing block 701 moves, the fixing block 701 will squeeze the first elastic member 13 to make the first elastic member 13 be stressed. Then the cover plate 2 is reset to make the card block 3 inserted into the inner cavity of the card slot 5. Finally, the pinching rod 703 is released. At this time, the second elastic member 14 will release the pulling force, so that the pushing block 702 drives the pinching rod 703 to reset at the same time. As the pushing block 702 is reset, the fixing block 701 will lose the squeezing force. At this time, the first elastic member 13 will release the elastic force, so that the fixing block 701 can better fix and clamp the fixing slot 8, and the adjustment is completed.

[0044] In summary: this efficiency-enhancing and emission-reducing device for IGCC power plant gas turbines achieves the effect of convenient use through the coordinated use of the efficiency-enhancing and emission-reducing device body 1, the cover plate 2, the card block 3, the mounting block 4, the card slot 5, the accommodating chamber 6, the card block fixing mechanism 7 and the fixing slot 8, and solves the problem that the existing emission reduction device needs to be operated at high altitude during maintenance and inspection, but the process of opening the protective shell for maintenance and inspection is complicated, which requires the user to perform high-altitude operations for a long time. As time goes by, long-term high-altitude operations will have uncertain risk factors, which will cause certain dangers to the user, not only wasting the user's time, but also causing unnecessary troubles to the user.
