Description

Technical Field

[0001] This utility model relates to the field of turbine guides, specifically a turbine guide that is easy to disassemble and replace parts. Background Technology

[0002] Turbine guide vanes are a key component of gas turbine engines, located between the turbine and the combustion chamber. Their main function is to guide and control gas flow. Through the shape and arrangement of the blades, the turbine guide vanes direct high-temperature, high-pressure gas from the combustion chamber to the turbine, achieving energy conversion. Turbine guide vanes not only help improve the efficiency and performance of gas turbine engines but also reduce energy loss. The "turbine guide vane for easy replacement of parts" disclosed in application number "CN221462388U" represents an increasingly mature technology. It involves "placing the outer ring on the front side of the bottom ring, causing the outer ring to engage with the mounting block on the outside of the fixed block, and rotating the mounting rod to achieve a threaded connection on the outer side of the middle of the mounting block." This allows the mounting rod to be threaded onto the outside of the fixing block, facilitating assembly between the outer ring and the bottom ring. However, this turbine guide has the following drawbacks during use: While the mounting block and mounting rod structure facilitates assembly between the outer ring and the bottom ring, the overall stability of the turbine guide's installation structure needs improvement. Therefore, it is necessary to provide a turbine guide that is easy to assemble and disassemble quickly and improves installation stability. Furthermore, the overall protective performance of this turbine guide is insufficient, which can lead to damage during use and affect its service life. Therefore, it is necessary to provide a turbine guide that improves protection and extends service life. Utility Model Content

[0003] The present invention provides a turbine guide that facilitates the disassembly and replacement of parts, aiming to solve the problems of insufficient installation stability and weak protective effect of existing turbine guides.

[0004] To achieve the above objectives, this utility model provides a turbine guide that facilitates disassembly and replacement of parts, including a guide assembly and a protective assembly;

[0005] The guide assembly includes an outer positioning ring, an inner positioning ring fixedly installed inside the outer positioning ring, a plurality of arc-shaped pieces detachably connected to the side surface of the inner positioning ring, blades fixedly connected to the side surface of each of the arc-shaped pieces, limit rings sleeved on the upper and lower side surfaces of each arc-shaped piece, a lead screw threaded to the side surface of the limit ring, and a limit nut threaded to the side surface of the lead screw.

[0006] The protective component includes a shock-absorbing mechanism installed inside the inner positioning ring, an outer protective net installed inside the upper end of the outer positioning ring, a positioning ring fixedly connected inside the outer protective net, the positioning ring being inserted into the inner positioning ring, and an inner protective net being provided inside the positioning ring.

[0007] As a preferred embodiment of this utility model, flanges are fixedly connected to both the upper and lower end surfaces of the outer positioning ring, positioning nuts are fixedly connected to both sides of the limiting ring, and the lead screw is threaded inside the positioning nuts.

[0008] As a preferred embodiment of this utility model, two connecting seats are fixedly connected to the upper and lower end side surfaces of the outer positioning ring, and two screw holes are opened on the inner walls of the upper and lower end of the outer positioning ring. The lead screw is threaded into the connecting seats and the screw holes.

[0009] As a preferred embodiment of this utility model, the side surface of the inner positioning ring is provided with a plurality of T-shaped grooves, and the inner walls of the plurality of arc-shaped pieces are fixedly connected with T-shaped strips, the T-shaped strips being snapped into the inside of the T-shaped grooves.

[0010] As a preferred embodiment of the present invention, the shock absorption mechanism includes a damper, and a buffer spring is sleeved on the side surface of the damper.

[0011] As a preferred embodiment of this utility model, a connecting ring is fixedly installed on the inner wall of the inner protective net.

[0012] As a preferred embodiment of this utility model, the damper is fixedly connected to both the upper and lower ends with plug-in blocks, which are respectively plugged into the bottom of the outer positioning ring and the inside of the connecting ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] During installation, firstly, the T-shaped strip is snapped into the T-groove to install the arc-shaped piece and its side surface blades inside the outer positioning ring and connect it with the inner positioning ring. Then, two limiting rings are fitted onto the inner positioning ring and the two end side surfaces of the arc-shaped piece. Next, the screw rod is threaded through the screw hole and the connecting seat and connected to the positioning nut to complete the installation of the turbine guide. During disassembly, firstly, the inner protective net is removed from the outer positioning ring. Then, the screw rod is simply removed from the positioning nut and the screw hole to pull the T-shaped strip out of the T-groove, thereby allowing the blades to be disassembled. Compared with the turbine guide structure in the existing technology "a turbine guide that facilitates the replacement of parts", this utility model can significantly improve the ease of disassembly and assembly of the turbine guide and improve the installation stability through the cooperation of the above structures, thereby enhancing the practicality of the turbine guide.

[0015] When the turbine guide is in use, the inner protective mesh effectively blocks dust, preventing it from entering the blades and affecting the turbine guide's performance. Simultaneously, the damper, in conjunction with the buffer spring, reduces vibrations acting on the outer protective mesh surface, thereby improving blade protection. Compared to the existing structure of "a turbine guide with easily replaceable parts," this invention, through the combined use of these structures, significantly improves the protection performance of the turbine guide, thus extending its service life.

[0027] In one specific embodiment, the guide assembly 100, in conjunction with the protective assembly 200, not only improves the ease of disassembly and replacement of each component, but also significantly enhances the installation stability of each component of the turbine guide, thereby improving the practicality of the turbine guide. Furthermore, the combined structure of the above components also facilitates improved protection of the turbine guide, thus extending its service life. During installation, the T-shaped strip 132 is first snapped into the T-groove 131, allowing the arc-shaped piece 103 and its side surface blades 104 to be installed inside the outer positioning ring 101 and connected to the inner positioning ring 102.

Two screw holes 122 are opened on the inner walls of the upper and lower ends of the outer positioning ring 101. The lead screw 106 is threaded into the connecting seats 121 and the screw holes 122.

[0031] In one specific embodiment, the lead screw 106 is threaded into the connecting seat 121, which can further enhance the installation stability of the turbine guide.

[0039] In one specific embodiment, the insertion block 20111 is inserted into the outer positioning ring 101 and the connecting ring 211, which can improve the ease of disassembly and assembly of the damper 2011.

[0040] Working principle: During installation, firstly, the T-shaped strip 132 is snapped into the T-shaped groove 131 to install the arc-shaped piece 103 and the blades 104 on its side surface inside the outer positioning ring 101, thereby connecting the arc-shaped piece 103 and the inner positioning ring 102. Then, two limiting rings 105 are fitted onto the inner positioning ring 102 and the two end side surfaces of several arc-shaped pieces 103. Next, the lead screw 106 is threaded through the screw hole 122 and the connecting seat 121 and threaded into the positioning nut 112, thereby completing the turbine guidance. During installation and disassembly, the inner protective net 204 is first removed from the outer positioning ring 101, and the lead screw 106 is removed from the positioning nut 112 and the screw hole 122.
