Description

Technical Field

[0001] The invention relates to the technical field of gas turbines, in particular to an air intake system silencer installation protection structure. Background Art

[0002] The acceleration of gas turbine localization and large-scale use has put forward higher requirements for the auxiliary system of gas turbines. The main task of the gas turbine intake system is to guide, compress and prepare the air for efficient combustion in the combustion chamber. This system is a vital component of the gas turbine and has a direct impact on the performance, efficiency and reliability of the gas turbine. As the only component that exists inside the gas turbine intake system after filtering, the reliability requirements of the silencer are extremely important.

[0003] However, in the air intake system, the presence of a silencer is particularly important. However, during the installation process, the existing air intake system silencers are often pushed into the channel after they are in place. This method is very likely to cause damage to the paint film of the channel due to the hard contact between the silencer and the channel, or debris is hidden at the bottom of the silencer and cannot be discovered and cleaned in time, and eventually falls and is sucked into the engine, damaging the engine blades. During the operation of the engine, the silencer of the air intake system will vibrate due to the properties of the engine itself and the airflow, resulting in continuous friction and collision with the channel, causing the paint film to fall off and debris to fall into the engine. Not only that, the surface of the existing silencer is usually not protected, which makes it easy for particles in the external dust to enter the silencer, thereby damaging it and affecting its normal operation. Summary of the invention

[0004] The object of the present invention is to provide an air intake system silencer installation protection structure to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: an air intake system silencer installation protection structure, comprising a first installation frame, and further comprising:

[0013] Preferably, a slot is provided inside the protective cover shell, and a filter plate for filtering dust particles is provided inside the slot.

[0014] Preferably, the two connecting plates are respectively fixed to the top and bottom of the inner cavity of the positioning shell, the pressing rod is arranged inside the positioning shell, sliding plates are arranged on both sides of the connecting plate, a second spring is fixedly connected between the opposite sides of the two sliding plates, an insert rod is fixedly connected to the side of the sliding plate away from the second spring, and an inclined plate is fixedly connected to one side of the pressing rod.

[0015] Preferably, a connecting rod is fixedly connected between the two sliding plates, and a roller is arranged on the surface of the connecting rod.

[0016] Preferably, the surface of the pressing rod is fixedly connected to a limiting ring, the surface of the limiting ring is provided with a circular shell, the side of the circular shell close to the positioning shell is fixedly connected to the positioning shell, one side of the limiting ring is fixedly connected to a third spring, and the side of the third spring away from the limiting ring is fixedly connected to the positioning shell.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When the silencer body is installed and plugged in, the polytetrafluoroethylene plate is driven by the arc column to fit the inside of the installation shell for plugging. The polytetrafluoroethylene plate itself has low friction resistance and a certain degree of plasticity. During the installation and sliding process of the silencer plate, the rigid contact between the silencer plate and the bottom surface of the air intake channel is isolated, protecting the paint film from being damaged. In addition, during the operation of the system, the polytetrafluoroethylene can limit the vibration of the silencer plate, play a certain degree of buffering role, and prevent the silencer plate from damaging the channel paint film;

Moreover, through the setting of the positioning assembly, when the user needs to disassemble the silencer plate for maintenance, the user can push the pressing rod to one side. At this time, the pressing rod will drive the limit ring to move inside the circular shell and squeeze the third spring at the same time. Then, the pressing rod will drive the inclined plate to press the two rollers to move to the opposite side. As the rollers move, the connecting rod will be driven to make the sliding plate move within the internal limit of the connecting plate. However, as the sliding plate moves, the plug rod will be driven to separate from the inside of the plug plate. Subsequently, the plug plate and the extension plate can be taken out to remove the silencer plate for maintenance. At the same time, it is convenient to install and position the silencer plate, reduce the difficulty of installation and positioning, and also improve the convenience of disassembly and assembly.

As the rollers 708 move, the connecting rod 707 will be driven to make the sliding plate 703 move within the internal limit of the connecting plate 701. However, as the sliding plate 703 moves, the inserting rod 705 will be driven to detach from the interior of the plug plate 9. Then the plug plate 9 and the extension plate 8 can be taken out to take out the silencer sheet 4 for maintenance.
