Description

Technical Field

[0001] This utility model relates to the field of gas turbine parts technology, and in particular to a gas turbine intake heating and silencing nozzle. Background Technology

[0002] The gas turbine intake system is one of the essential auxiliary systems for gas turbines. It provides the clean air required for the combustion process and plays a crucial role in the safe and reliable operation of gas turbine power plants.

[0003] The filter is the core of the air intake system. Due to its material and the pollutants it adsorbs, the filter pressure differential can increase when the ambient humidity is high, a phenomenon known as "wet blockage." Under certain specific climatic conditions, ice can even form on the filter surface, blocking the air intake passage and causing "ice blockage." This poses a significant threat to the safe and reliable operation of the gas turbine.

[0004] Gas turbines operate in many different regions, from polar regions to tropical zones, from deserts to oceans. In some extreme cases, ice can form at the gas turbine inlet bellows or on the IGV (Intake Gas Vent), posing a risk of foreign object damage to the compressor blades.

[0005] The aforementioned problems can be solved using a gas turbine intake heating system. Conventional intake heating systems draw a portion of high-temperature, high-pressure gas from the compressor and inject it into the intake system to mix with the drawn-in cold air, thereby providing intake temperature. However, to evenly inject the high-temperature, high-pressure gas from the compressor into the intake system and ensure thorough and uniform mixing of the hot and cold air, a special nozzle is required. Simultaneously, the injection of high-pressure gas into the intake system also generates significant noise, which also needs to be reduced to a certain level using this nozzle.

[0006] The prior art publication CN209385239U discloses a noise-reducing heating nozzle for a gas turbine intake anti-icing and anti-humidity device. The nozzle connects the intake pipe, intermediate pipe, and exhaust pipe sequentially from the inside to the outside, filling the spaces between each pipe with a multi-layered, multi-mesh metal mesh. This significantly reduces turbulence and impact noise, achieving a total noise reduction of up to 40 dB in practice. Heating nozzles using this structure offer numerous advantages, including long replacement cycles, low manufacturing and operating costs, excellent noise reduction, and high safety and reliability.

[0007] During the use of the intake heating and silencing nozzle, dust particles may be carried in the air. These particles may deposit in the intake duct. If the particles adhere to the inner wall of the intake heating and silencing nozzle, and the existing technology does not facilitate the automatic maintenance of the inner wall of the intake heating and silencing nozzle, it will lead to poor airflow and affect the heating and silencing effect.

[0008] In summary, the existing technology lacks a technique for automatically maintaining the inner wall of the intake heating silencer nozzle. Utility Model Content

A steel wire rope is wound around the outer wall of the roller, and a bristle sleeve is fitted on the outer wall of the steel wire rope. The free end of the steel wire rope passes through the bottom end of the take-up seat and is fixedly connected to a magnetic ball.

[0013] Preferably, the output end of the inflatable seat extends through the outer wall of one of the sealing seats into the interior and is fixedly connected to a bellows. The other end of the bellows is fixedly connected to the inner wall of one of the adjusting seats. A piston is slidably fitted onto the inner wall of the inflatable seat. A spring is fixedly connected to the piston. The other end of the spring is fixedly connected to the inner wall of the inflatable seat. A contact rod is fixedly connected to the lower side of the piston.

[0014] Preferably, a motor B is fixedly installed at the bottom of the inflatable base, and a transmission wheel is fixedly connected to the output end of the motor B.

[0015] Preferably, a driven wheel is fixedly connected to the bottom end of the rotating frame, an electric actuator B is fixedly connected inside the rotating frame, the output end of the electric actuator B is fixedly connected to the limit seat, and a trapezoidal strip is fixedly connected to the rotating frame.

[0016] Preferably, the top of the limiting seat is provided with an adsorption groove, and a magnet is fixedly connected in the adsorption groove. The magnet is magnetically connected to the magnetic ball. Multiple limiting rods are rotatably connected in a ring structure on the outer side of the upper end of the limiting seat. The other end of the limiting rod abuts against the outer wall of the magnetic ball. A gear is fixedly connected to the end of the limiting rod that is connected to the limiting seat.

[0017] Preferably, a movable ring is slidably fitted on the limiting seat, and multiple racks are fixedly connected to the top of the movable ring. The racks are meshed with gears for transmission.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting up a nozzle inner wall maintenance mechanism, when the inner wall of the silencer nozzle needs to be cleaned and maintained, the magnetic ball can move the steel wire rope downward and stretch under its own weight. Then, the magnetic ball is fixed in conjunction with the limit seat. When the rotating frame drives the limit seat to rotate, it will cause the steel wire rope to swing up, so that the bristles on the outer wall of the steel wire rope can effectively fit the inner wall of the silencer nozzle during the rotation, achieving a comprehensive and uniform cleaning effect, reducing the accumulation of dirt. Compared with the traditional manual cleaning method, it can more effectively maintain the operating status of the equipment and improve the overall work efficiency and equipment reliability.

[0021] 2. By setting up an air inflation base, air can be continuously inflated into the silencer nozzle while cleaning and maintaining the inner wall of the silencer nozzle. This allows the dust particles generated during cleaning to be discharged through the exhaust groove and filtered by the filter cartridge, effectively preventing dust and dirt from flowing back into the inner wall of the nozzle. This keeps the nozzle's interior smooth and clean, helps improve the stability of airflow, effectively reduces pollution to the surrounding environment, and ensures air quality in the workplace.

[0022] 3. By setting up a transmission mechanism, when motor B drives the piston to move, it can also drive the transmission mechanism, which in turn drives the rotating frame to rotate. This, in turn, causes the wire rope to swing up for cleaning and maintenance. The linkage design between motor B driving the piston and the rotating frame and wire rope can effectively improve the efficiency and quality of cleaning and maintenance, reduce maintenance costs, enhance safety, and has good environmental protection properties.

[0032] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0033] like Figures 1-8 The gas turbine intake heating silencer nozzle shown includes a heating main pipe 1, on which multiple heating branch pipes 2 are fixedly installed. A silencer nozzle 3 is fixedly connected to each heating branch pipe 2. A sealing seat 4 is fixedly connected through both ends of each heating branch pipe 2. An adjusting seat 5 is slidably fitted inside the sealing seat 4. One adjusting seat 5 has a nozzle inner wall maintenance mechanism 6 fixedly connected inside it, and an air filling seat 7 is fixedly connected to its lower side. A rotating frame 8 is rotatably connected inside the other adjusting seat 5. A limit seat 9 is slidably fitted onto the rotating frame 8, and a transmission mechanism 10 is located on one side of the rotating frame 8. The multiple heating branch pipes 2 fixedly installed on the heating main pipe 1 enable the hot air to be ejected in a columnar shape, reducing the unevenness present in the circular ejection of imported products. This results in more uniform mixing of hot and cold air, better mixing effect, and a smaller temperature difference in the mixed air, leading to a larger hot air ejection hole area and lower hot air velocity, thus reducing noise.

[0034] like Figure 3As shown, an electric actuator A501 is fixedly connected to one end of the adjusting seat 5, and the other end of the electric actuator A501 is fixedly connected to the inner wall of the sealing seat 4. An air guide hole 502 is provided on one side of the adjusting seat 5, and an exhaust groove 503 is slidably fitted through the inner wall of one of the adjusting seats 5. The exhaust groove 503 is fixedly connected through the inner wall of the sealing seat 4, and a filter cartridge 504 is threadedly connected to the outer end of the exhaust groove 503. The threaded filter cartridge 504 facilitates cleaning of the filtered material on its inner wall. The electric actuator A501 moves the adjusting seat 5, causing the air guide hole 502 on the adjusting seat 5 to open. At this time, the two adjusting seats 5 can seal both ends of the heating branch pipe 2.

[0035] like Figure 4 As shown, the nozzle inner wall maintenance mechanism 6 includes a take-up seat 601, on which a shaft 602 is rotatably connected. A motor A603 is fixedly connected to one end of the shaft 602, and the motor A603 is fixedly connected to the take-up seat 601. A steel wire rope 604 is wound around the outer wall of the shaft 602, and a bristle sleeve 605 is fitted over the outer wall of the steel wire rope 604. The free end of the steel wire rope 604 passes through the bottom of the take-up seat 601 and is fixedly connected to a magnetic ball 606. When the motor A603 drives the connected shaft 602 to rotate, the steel wire rope 604 wound on the shaft 602 will move downwards under the action of the magnetic ball 606. The magnetic ball 606 will then fall into the adsorption groove 901 on the limiting seat 9, where it is adsorbed by the magnet 902.

[0036] By setting up the nozzle inner wall maintenance mechanism 6, when the inner wall of the silencer nozzle 3 needs to be cleaned and maintained, the magnetic ball 606 can drive the steel wire rope 604 to move downward and stretch under its own weight. Then, the magnetic ball 606 is fixed in conjunction with the limit seat 9. When the rotating frame 8 drives the limit seat 9 to rotate, it will drive the steel wire rope 604 to swing up, so that the bristle sleeve 605 on the outer wall of the steel wire rope 604 can effectively fit the inner wall of the silencer nozzle 3 during the rotation, achieving a comprehensive and uniform cleaning effect, reducing the accumulation of dirt. Compared with the traditional manual cleaning method, it can more effectively maintain the operating status of the equipment and improve the overall work efficiency and equipment reliability.

[0037] like Figure 5 As shown, the output end of the inflation seat 7 extends through the outer wall of one of the sealing seats 4 and is fixedly connected to a bellows 701. The other end of the bellows 701 is fixedly connected to the inner wall of one of the adjusting seats 5. A piston 702 is slidably fitted onto the inner wall of the inflation seat 7. A spring 703 is fixedly connected to the piston 702, and the other end of the spring 703 is fixedly connected to the inner wall of the inflation seat 7. A contact rod 704 is fixedly connected to the lower side of the piston 702. One-way valves are installed in both the input and output ends of the inflation seat 7. The spring 703 drives the piston 702 to automatically reset.

[0038] A motor B705 is fixedly mounted at the bottom of the inflation base 7. A transmission wheel 706 is fixedly connected to the output end of the motor B705. Multiple protrusions 707 are fixedly connected to the transmission wheel 706, and the protrusions 707 are in slidable contact with the contact rod 704. When the transmission wheel 706 rotates, it pushes the piston 702 connected to the contact rod 704 through the multiple protrusions 707, allowing the piston 702 to inject air from the inflation base 7 into the silencer nozzle 3.

[0039] like Figure 6 As shown, a driven wheel 801 is fixedly connected to the bottom of the rotating frame 8, an electric actuator B802 is fixedly connected inside the rotating frame 8, the output end of the electric actuator B802 is fixedly connected to the limit seat 9, and a trapezoidal strip 803 is fixedly connected to the rotating frame 8.

[0040] like Figure 7 As shown, the top of the limiting seat 9 is provided with an adsorption groove 901, and a magnet 902 is fixedly connected in the adsorption groove 901. The magnet 902 is magnetically connected to the magnetic ball 606. Multiple limiting rods 903 are rotatably connected in a ring structure on the outer side of the upper end of the limiting seat 9. The other end of the limiting rod 903 abuts against the outer wall of the magnetic ball 606. A gear 904 is fixedly connected to one end of the limiting rod 903 that is connected to the limiting seat 9.

[0041] A movable ring 905 is slidably fitted onto the limiting seat 9. Multiple racks 906 are fixedly connected to the top of the movable ring 905, meshing with gears 904 for transmission. Multiple tension springs 907 are fixedly connected to the lower side of the movable ring 905, with the other end of each spring fixedly connected to the limiting seat 9. A contact wheel 908 is rotatably connected to one end of the movable ring 905, slidingly contacting the trapezoidal bar 803. The tension springs 907 enable the movable ring 905 to automatically reset. When the electric actuator B802 moves the connected limiting seat 9 to a position offset from the center of the rotating frame 8, the contact wheel 908, under the action of the trapezoidal bar 803, causes the connected movable ring 905 to move upwards. The movable ring 905 then drives the gears 904 to rotate via the multiple racks 906, causing the gears 904 to rotate the connected limiting rod 903.

[0042] like Figure 8As shown, the transmission mechanism 10 includes a telescopic rod 1001. Both ends of the telescopic rod 1001 are rotatably connected to the sealing seat 4 and the adjusting seat 5, respectively. One end of the telescopic rod 1001 located inside the adjusting seat 5 is fixedly connected to a drive wheel 1002, which meshes with the driven wheel 801 for transmission. The other end of the telescopic rod 1001 is fixedly connected to a universal joint 1003, which is rotatably connected to the sealing seat 4. The other end of the universal joint 1003 is fixedly connected to an adjusting wheel 1004, which meshes with the transmission wheel 706 for transmission. The motor B705 drives the connected transmission wheel 706 to rotate. At this time, the transmission wheel 706 drives the universal joint 1003 connected to the adjusting wheel 1004 to rotate, so that the universal joint 1003 can drive the drive wheel 1002 connected to the telescopic rod 1001 to rotate. At this time, the drive wheel 1002 drives the rotating frame 8 connected to the driven wheel 801 to rotate, thereby driving the steel wire rope 604 connected to the magnetic ball 606 to swing up.

[0043] Working principle: When it is necessary to clean and maintain the inner wall of the silencer nozzle 3, the electric push rod A501 is used to drive the adjustment seat 5 to move, so that the air guide hole 502 on the adjustment seat 5 is removed. At this time, the two adjustment seats 5 can seal the two ends of the heating branch pipe 2. Then, the motor A603 drives the connected roller 602 to rotate. At this time, the steel wire rope 604 wound on the roller 602 will move down under the action of the magnetic ball 606. Then the magnetic ball 606 will fall into the adsorption groove 901 on the limit seat 9 and be adsorbed by the magnet 902.

[0044] Then, the electric actuator B802 drives the connected limit seat 9 to move to a position away from the center of the rotating frame 8. At this time, under the action of the trapezoidal bar 803, the contact wheel 908 will drive the connected movable ring 905 to move upward. At this time, the movable ring 905 will drive the gear 904 to rotate through multiple racks 906, which will drive the connected limit rod 903 to rotate and press on the magnetic ball 606 for limiting.

[0045] Then, the motor B705 drives the connected transmission wheel 706 to rotate. At this time, the transmission wheel 706 drives the universal joint 1003 connected to the adjusting wheel 1004 to rotate, so that the universal joint 1003 can drive the drive wheel 1002 connected to the telescopic rod 1001 to rotate. At this time, the drive wheel 1002 drives the rotating frame 8 connected to the driven wheel 801 to rotate, thereby driving the steel wire rope 604 connected to the magnetic ball 606 to swing up, so that the steel wire rope 604 sticks to the inner wall of the muffler nozzle 3, and works with the brush sleeve 605 to clean and maintain the inner wall of the muffler nozzle 3.

[0046] At the same time, when the drive wheel 706 rotates, the piston 702 connected to the contact rod 704 will be moved by multiple protrusions 707, so that the piston 702 can inject the air in the air seat 7 into the silencer nozzle 3 through the air seat 7, thereby discharging the dust generated during cleaning through the exhaust groove 503 and filtering it through the filter cartridge 504.
