Description

Technical Field

[0001] The present application relates to the technical field of gas turbines, and in particular to a shielding mechanism for an endoscope port of a gas turbine. Background Art

[0002] Gas turbines are core equipment in power generation and propulsion. The combustion chamber is a core component of a gas turbine, converting the chemical energy of the fuel into thermal energy to propel the turbine. During gas turbine combustion chamber testing, an endoscope is inserted into the combustion chamber to observe and record the operating conditions of the combustion chamber. This is exemplified by the Chinese patent application CN113507556A, which describes an endoscope assembly for gas turbines.

[0003] At present, there is no good lens protection structure in the endoscopes used. When the lens is not in use, since there is a lot of dust and impurities in the gas turbine, if the lens is not covered and protected, dust will adhere to the lens surface, which limits the use of the lens and affects the endoscopic inspection of the gas turbine. Therefore, a shielding mechanism for the endoscope port of the gas turbine is designed to solve the above-mentioned problems. Utility Model Content

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The embodiment of the present application discloses a shielding mechanism for an endoscope port of a gas turbine. Figure 1-3 A shielding mechanism for an endoscope port of a gas turbine includes a lens body 1, with rotating rods 2 fixedly connected to both sides of the lens body 1, the rotating rod 2 being rotatably connected to a mounting block 3 on a side away from the lens body 1, the upper end of the mounting block 3 being fixedly connected to a mounting rod 4, the upper end of the mounting rod 4 being slidably connected to a mounting tube 5, the upper end of the mounting tube 5 being fixedly connected to a protective cover 7, the lower end of the protective cover 7 being rotatably connected to a mounting plate 8, the lower end of the mounting plate 8 being fixedly connected to a wiping cloth 9, the mounting rod 4 being driven to rotate about the rotating rod 2 as the axis by the mounting block 3, and the mounting tube 5 and the protective cover 7 being driven to rotate to the lens of the lens body 1, and then the protective cover 7 being released, so that the upper end of the protective cover 7 is lowered, so that the wiping cloth 9 contacts the surface of the lens, and the protective ring 11 and the protective cover 7 cover the lens, thereby covering and protecting the lens;

[0021] By adopting the above technical solution, the upper end of the mounting plate 8 passes through the protective cover 7 and is fixedly connected to the handle 10, and the handle 10 is provided with anti-slip grooves, which facilitates the rotation of the mounting plate 8, so that the mounting plate 8 drives the wiping cloth 9 to wipe the lens.

[0022] By adopting the above technical solution, the protective cover 7 is fixedly connected to the protective ring 11. The diameter of the protective ring 11 is larger than the diameter of the lens body 1. The provided protective ring 10 is used to cover the lens body 1 to play a role in covering and protecting the lens.

[0023] By adopting the above technical solution, the mounting block 3 is fixedly connected to the torsion spring 12 on the side close to the rotating rod 2, and one end of the torsion spring 12 is fixedly connected to the side wall of the lens body 1. The provided torsion spring 12 helps to drive the mounting block 3 to rotate, so that the mounting block 3 drives the mounting rod 4 to rotate, thereby rotating the protective cover 7 to the front of the lens body 1 to cover and protect the lens.

[0024] By adopting the above technical solution, a protective frame 13 is fixedly connected to the front side wall of the lens body 1. The protective frame 13 is circular and is used to protect the wiping cloth 9 when not in use.

[0025] By adopting the above technical solution, the front part of the lower end of the protective frame 13 is fixedly connected to the No. 2 tension spring 14, and the front part of the No. 2 tension spring 14 is fixedly connected to the clamping plate 15. The No. 2 tension spring 14 is used to drive the clamping plate 15 to restore, so that the clamping plate 15 covers the protective frame 13 to prevent dust from entering the protective frame 13 and polluting the interior.

[0026] By adopting the above technical solution, the upper end of the mounting rod 4 is fixedly connected to the No. 1 tension spring 41, and the upper end of the No. 1 tension spring 41 is fixedly connected to the inner wall of the mounting tube 5. The No. 1 tension spring 41 is provided to drive the mounting tube 5 to descend, so that the protective cover 7 on the mounting tube 5 descends, which is beneficial for the protective cover 7 to cover the lens for protection.

[0027] The implementation principle of the shielding mechanism for the endoscope port of a gas turbine in an embodiment of the present application is as follows: first pull the clamping plate 15 so that the clamping plate 15 drives the second tension spring 14 to extend, and separates the clamping plate 15 from the back of the protective cover 7, and then pull the protective cover 7 so that the protective cover 7 drives the mounting tube 5 to move and extend, and the first tension spring 41 to extend. At this time, the twisted torsion spring 12 drives the mounting block 3 to restore, so that the mounting block 3 drives the mounting rod 4 to rotate with the rotating rod 2 as the axis, and drives the mounting tube 5 and the protective cover 7 to rotate to the lens of the lens body 1, and then release the protective cover 7, so that the first tension spring 41 drives the mounting tube 5 to descend, and the upper end protective cover 7 is descended, so that the wiping cloth 9 contacts the lens surface, and the protective ring 11 and the protective cover 7 cover the lens to cover and protect the lens.

[0028] When it is needed, the handle 10 can be turned to drive the mounting plate 8 to rotate, and the mounting plate 8 drives the wiping cloth 9 to rotate, so that the wiping cloth 9 wipes the lens to keep the lens clean. Then, the mounting tube 5 is pulled to separate the protective cover 7, the mounting plate 8 and the wiping cloth 9 from the lens. Then, the mounting block 3 is turned again, and the clamping plate 15 is pulled. The mounting block 3 drives the protective cover 7 to flip and move between the clamping plate 15 and the protective frame 13 again. Then, the clamping plate 15 is released so that the clamping plate 15 contacts and squeezes the protective cover 7, so that the mounting plate 8 and the wiping cloth 9 of the protective cover 7 enter the protective frame 13 again for protection.
