Description

Technical Field

[0001] This utility model relates to the field of gas turbine technology, specifically to a quick-release installation structure for a gas turbine exhaust temperature measurement module. Background Technology

[0002] Gas turbine exhaust temperature measurement modules are typically installed using flange bolts or welding. Traditional flange structures require individual bolt removal, which can easily deform and jam under high temperatures, taking 1-2 hours. Welded structures require cutting and damaging the original casing, resulting in downtime exceeding 8 hours. Existing quick-release structures mostly rely on spring clips, but high temperatures (>600℃) cause the elastic elements to fail, and they lack vibration-resistant loosening mechanisms, leading to low measurement accuracy. Therefore, we propose a quick-release installation structure for gas turbine exhaust temperature measurement modules. Summary of the Invention

[0003] The purpose of this invention is to address the problems of traditional flange structures requiring individual bolt removal, which leads to bolt deformation and jamming under high temperatures, taking 1-2 hours. Welded structures require cutting and damaging the original casing, resulting in downtime exceeding 8 hours. Existing quick-release structures mostly rely on spring clips, but high temperatures (>600℃) cause the elastic elements to fail, and there is a lack of vibration-resistant loosening mechanisms, resulting in low measurement accuracy. This invention provides a quick-release installation structure for a gas turbine exhaust temperature measurement module.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A quick-release installation structure for a gas turbine exhaust temperature measurement module includes a fixed base. The rear end of the fixed base is welded and fixed to the inner wall of the exhaust pipe. A thermocouple temperature measurement module is inserted into the front side of the fixed base. A thermocouple housing is fixed to the rear side of the thermocouple temperature measurement module, and the thermocouple housing matches the inner wall of the fixed base. A disc spring assembly is inserted into the rear end of the inner cavity of the fixed base, and the front side of the disc spring assembly abuts against the rear end of the thermocouple housing. A threaded pressure plate is threadedly connected to the front side of the thermocouple temperature measurement module. The threaded pressure plate is sleeved on the thermocouple temperature measurement module, and the rear end of the threaded pressure plate can press the front side of the thermocouple housing tightly.

[0006] Furthermore, the front circumference of the thermocouple housing is conical, and a conical locking ring is fitted on the front side of the thermocouple temperature measuring module. The rear end of the conical locking ring is provided with a conical neck that abuts against the thermocouple housing, and the rear side of the threaded pressure plate abuts against the front side of the conical locking ring.

[0007] Furthermore, the front outer ring of the threaded pressure plate has multiple mating holes arranged in an annular array, and these multiple mating holes can mate with the protrusions of the quick-release throttle.

[0008] Furthermore, a fixing bolt is inserted through the center of the docking hole on the left side, and the fixing bolt passes through the threaded pressure plate and is threadedly connected to the front side of the fixing base.

[0009] Furthermore, the inner wall of the fixed base is fixed with multiple V-shaped protrusions, and the side wall of the thermocouple housing is provided with multiple positioning slots corresponding to the positions of the V-shaped protrusions.

[0010] Furthermore, the fixed base has a cooling cavity inside, and a spiral guide vane is fixedly connected to the inner wall of the cooling cavity. The side wall of the fixed base is provided with a cooling air inlet, and the cooling air inlet is connected to the cooling cavity. Multiple exhaust holes are provided on the outer circumferential surface of the fixed base near the front side of the cooling cavity.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. In use, the thermocouple temperature measuring module is inserted into the fixed base, and the thermocouple shell mates with the inner wall of the fixed base. A threaded pressure plate is threaded onto the thermocouple temperature measuring module, with the rear end of the threaded pressure plate pressing against the front side of the thermocouple shell. At this time, the disc spring assembly is compressed, generating a radial locking force, ensuring a tight contact between the thermocouple temperature measuring module and the fixed base, guaranteeing accurate temperature measurement. When it is necessary to disassemble the thermocouple temperature measuring module, simply unscrew the threaded pressure plate to easily pull the thermocouple temperature measuring module out of the fixed base, achieving a quick-release function for easy replacement or maintenance. The entire installation structure is compact and reasonable, and the operation is simple and convenient, greatly improving work efficiency.

[0013] 2. This utility model, through the design of a conical locking ring, which mates with the conical surface of the thermocouple housing, enables automatic centering during threaded clamping. This further enhances the connection stability between the thermocouple temperature measurement module and the fixed base, preventing loosening due to vibration in high-temperature environments and ensuring the stability and accuracy of temperature measurement.

[0014] 3. The present invention, through the setting of the docking hole, facilitates the quick rotation of the threaded pressure plate using the quick-release throttle, realizing the quick assembly and disassembly of the thermocouple temperature measurement module, further improving work efficiency and making operation more convenient.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0020] Please see Figures 1-3 This utility model provides a quick-release installation structure for a gas turbine exhaust temperature measurement module, including a fixed base 1. The rear end of the fixed base 1 is welded and fixed to the inner wall of the exhaust pipe, and a thermocouple temperature measurement module 2 is inserted into the front side of the fixed base 1. A thermocouple housing 7 is fixed to the rear side of the thermocouple temperature measurement module 2, and the thermocouple housing 7 matches the inner wall of the fixed base 1. A disc spring assembly 5 is inserted into the rear end of the inner cavity of the fixed base 1, and the front side of the disc spring assembly 5 abuts against the rear end of the thermocouple housing 7. A threaded pressure plate 8 is threadedly connected to the front side of the thermocouple temperature measurement module 2. The threaded pressure plate 8 is sleeved on the thermocouple temperature measurement module 2, and the rear end of the threaded pressure plate 8 can press the front side of the thermocouple housing 7 tightly.

[0021] The working principle and usage process of this utility model are as follows: In use, the thermocouple temperature measuring module 2 is inserted into the fixed base 1. The thermocouple shell 7 mates with the inner wall of the fixed base 1. The threaded pressure plate 8 is threaded onto the thermocouple temperature measuring module 2. The rear end of the threaded pressure plate 8 presses the front side of the thermocouple shell 7 tightly. At this time, the disc spring assembly 5 is compressed, generating a radial locking force, ensuring a tight contact between the thermocouple temperature measuring module 2 and the fixed base 1, guaranteeing the accuracy of temperature measurement. When it is necessary to disassemble the thermocouple temperature measuring module 2, simply unscrew the threaded pressure plate 8 to easily pull the thermocouple temperature measuring module 2 out of the fixed base 1, achieving a quick-release function for easy replacement or maintenance. The entire installation structure is compact and reasonable, and the operation is simple and convenient, greatly improving work efficiency.

[0022] In this embodiment, preferably, the front circumference of the thermocouple housing 7 is conical, and a conical locking ring 6 is fitted on the front side of the thermocouple temperature measuring module 2. The rear end of the conical locking ring 6 is provided with a conical neck that matches the thermocouple housing 7, and the rear side of the threaded pressure plate 8 abuts against the front side of the conical locking ring 6. By setting the conical locking ring 6, the conical locking ring 6 cooperates with the conical surface of the thermocouple housing 7, and can automatically center through the conical surface cooperation when the threaded pressure plate 8 is pressed, which further enhances the connection stability between the thermocouple temperature measuring module 2 and the fixed base 1, prevents loosening due to vibration in high-temperature environments, and ensures the stability and accuracy of temperature measurement.

[0023] In this embodiment, preferably, the front outer ring of the threaded pressure plate 8 is provided with a plurality of docking holes 9, and the plurality of docking holes 9 can dock with the protrusion of the quick-release throttle; the docking holes 9 facilitate the quick rotation of the threaded pressure plate 8 using the quick-release throttle, thereby realizing the quick assembly and disassembly of the thermocouple temperature measurement module 2, further improving work efficiency and making operation more convenient.

[0024] In this embodiment, preferably, a fixing bolt 10 is inserted through the center of the docking hole 9 on the left side. The fixing bolt 10 passes through the threaded pressure plate 8 and is threadedly connected to the front side of the fixing base 1. The fixing bolt 10 can fix the threaded pressure plate 8 to prevent it from loosening, thus ensuring the stability of the connection between the thermocouple temperature measuring module 2 and the fixing base 1. At the same time, when the quick-release handle is not used, the threaded pressure plate 8 can be fixed by the fixing bolt 10, which improves the safety of the entire installation structure.

[0025] In this embodiment, preferably, the inner wall of the fixed base 1 is arrayed with multiple V-shaped protrusions 12, and the side wall of the thermocouple housing 7 is provided with multiple positioning slots 11 corresponding to the positions of the V-shaped protrusions 12. Through the cooperation of the V-shaped protrusions 12 and the positioning slots 11, the thermocouple housing 7 can be positioned when inserted into the fixed base 1, resulting in a tighter fit between the thermocouple housing 7 and the fixed base 1, further improving the accuracy and stability of temperature measurement. Simultaneously, the V-shaped protrusions 12 and the positioning slots 11 also enhance the connection strength between the thermocouple housing 7 and the fixed base 1, preventing loosening of the connection due to thermal expansion and contraction in high-temperature environments.

[0026] In this embodiment, preferably, a cooling cavity 13 is formed inside the fixed base 1, and a spiral guide vane 3 is fixedly connected to the inner wall of the cooling cavity 13. A cooling air inlet 4 is provided on the side wall of the fixed base 1, and the cooling air inlet 4 communicates with the cooling cavity 13. Multiple exhaust holes are formed on the outer circumferential surface of the fixed base 1 near the front side of the cooling cavity 13. Through the cooling cavity 13, a cooling air pump connected to the cooling air inlet 4 can be connected to the cooling air inlet 4 to introduce cooling air into the cooling cavity 13. Under the guidance of the spiral guide vane 3, the cooling air can flow evenly and quickly through the cooling cavity 13. Through heat exchange with the spiral guide vane 3 and the inner wall of the cooling cavity 13, the temperature of the fixed base 1 is reduced, thereby avoiding the adverse effects of high temperature on the temperature measuring module and improving the accuracy and service life of the temperature measuring module. At the same time, after the cooling air flows through the cooling cavity 13, it is discharged through the exhaust holes, forming an effective heat dissipation channel, further enhancing the heat dissipation effect. In addition, the design of the spiral guide vane 3 can not only guide the cooling air to flow evenly through the cooling chamber 13, but also increase the contact area between the cooling air and the inner wall of the cooling chamber 13, improve the heat exchange efficiency, and ensure that the fixed base 1 is adequately cooled.
