Description

Technical Field

[0001] The invention relates to the technical field of gas turbines, and in particular to a high-temperature and high-speed exhaust gas guide structure. Background Art

[0002] A gas turbine is a device that generates high-temperature and high-pressure gas by burning fuel and uses this gas to drive the turbine to rotate. It is mainly composed of three parts: a compressor, a combustion chamber, and a turbine. The compressor compresses the air, and the fuel and compressed air in the combustion chamber are mixed and burned. The high-temperature gas generated drives the turbine to rotate, and finally converts mechanical energy into electrical energy or uses it for propulsion. Gas turbines are widely used in power generation, aviation, and industrial fields. The accelerated localization and large-scale use of gas turbines have put forward higher requirements for the auxiliary system of gas turbines. In order to protect the environment, the exhaust port of the gas turbine often needs to ensure a certain height, so it is necessary to change the airflow direction of the exhaust gas.

[0003] However, the existing exhaust duct has no diversion design, resulting in excessive gas flow resistance, chaotic airflow, and secondary noise pollution such as whistling. In addition, excessive airflow will cause certain damage to the internal structure. Although there are guide plates installed in the duct, the existing guide plates have a single function. After installation, it is not convenient to automatically adjust the guide angle, which affects the diversity of use. Moreover, when the existing exhaust pipe is connected to the exhaust duct, it is usually necessary to install multiple screws to connect them. This means that when disassembling and maintaining the duct, it is still necessary to use tools to remove multiple screws to maintain the inside of the duct, which greatly increases the difficulty of maintenance.

Rotate the shell 1110, and one side of the rotating shell 1110 is fixedly connected with the third spring 1111, and one side of the third spring 1111 is fixedly connected with the positioning ring 1112. When the user needs to remove the mounting plate 7 to maintain the pipeline, the pulling ball 1115 can be pulled to make the positioning ring 1112 drive the inclined block 1113 to disengage from the interior of the slot 1109. At the same time, the positioning ring 1112 will squeeze the third spring 1111, and then twist the rotating rod 1102 to drive the gear 1103 to engage the two tooth plates 1104 to move in opposite directions. As the tooth plates 1104 move, the insertion rod 1105 will be driven to disengage from the interior of the insertion plate 10, and one side of the positioning ring 1112 is fixedly connected with the inclined block 1113 used to cooperate with the slot 1109, and one side of the positioning ring 1112 is fixedly connected with the positioning rod 1114.

[0036] Working principle: First, connect the mounting hole 8 on the mounting plate 7 with other pipes, then drive the plug plate 10 to be inserted into the mounting shell 6 by the connecting plate 9 on the mounting plate 7, and the plug plate 10 can be supported by the partition plate 20. At this time, rotating the rotating rod 1102 will drive the rotating shell 1110. At this time, since the inclined surface of the inclined block 1113 is the same as the inclined surface of the slot 1109, directly rotating the rotating rod 1102 forward will cause the gear 1103 to rotate and engage the toothed plate 1104 to drive the slider 1106 to move within the internal limit of the slide slot 1107, and then the toothed plate 1104 will also drive the plugging rod 1105 to insert The first inner cylinder 201 is inserted into the interior of the plug plate 10 to complete its positioning and installation, and the other side of the inclined block 1113 is pressed against the interior of the card slot 1109 to prevent it from loosening. Then, during normal airflow, when the high-temperature and high-speed airflow flows in from one side of the first inner cylinder 201, the airflow is guided to other directions through a plurality of curved guide plates 505. At the same time, the plurality of guide plates 505 can also comb the high-speed chaotic airflow into a uniform airflow, reducing the pressure and reducing the flow resistance. When the user needs to adjust the amplitude of the guide plate 505, the motor 501 is controlled to drive the screw 503 to rotate through the output end of the motor 501. When the threaded sleeve 507 moves, the threaded sleeve 507 will drive the positioning plate 508 to move the fixing frame 509. During the movement of the threaded sleeve 507, the sliding plate 511 will also be driven to move on the surface of the sliding rod 512. The fixing frame 509 cooperates with the limiting rod 510 to enable the connecting frame 504 to drive the guide plate 505 to float up and down to adjust the guide angle, thereby improving the diversity of use and facilitating the adjustment of the wind direction of the guide. When the user needs to repair the motor 501, the pull plate 19 can be pulled to drive the pull rod 18 to make the block 17 squeeze the first spring 16, and then the block 17 will be separated from the fixing plate 15 The door panel 13 can then be opened for maintenance. When the user needs to remove the mounting plate 7 to maintain the pipeline, the pull ball 1115 can be pulled to make the positioning ring 1112 drive the inclined block 1113 to disengage from the interior of the slot 1109. At the same time, the positioning ring 1112 will squeeze the third spring 1111. Then, the rotating rod 1102 is twisted to drive the gear 1103 to engage the two tooth plates 1104 and move in opposite directions. As the tooth plates 1104 move, the insertion rod 1105 will be driven to disengage from the interior of the insertion plate 10. At this time, the second spring group 22 will also release the restriction and drive the movable plate 23 to assist in popping out the insertion plate 10.
