Description

Technical Field

[0001] This utility model relates to the field of sound barrier technology, specifically to an adjustable bracket for a gas turbine air inlet sound barrier. Background Technology

[0002] During the operation of a gas turbine, the air inlet generates high-intensity noise, which needs to be controlled by setting up a sound barrier. The stable installation of the sound barrier depends on the corresponding support structure.

[0003] Currently, the supports used in existing gas turbine inlet sound barriers are mostly fixed structures, mainly composed of columns and beams of fixed length, with the beams rigidly connected to the columns by welding or bolts. This fixed-length support has significant limitations: because the width of the inlet varies between different models and power outputs of gas turbines, the fixed-length support can only accommodate inlets of specific sizes. When the gas turbine model is changed or the inlet size is adjusted, the original support cannot be adjusted in length to meet the new installation requirements, necessitating the customization of new supports. This not only increases the cost of equipment replacement but also extends the construction period. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable bracket for a gas turbine inlet sound barrier, which effectively solves the technical problem that existing gas turbine inlet sound barrier brackets have a fixed length and cannot flexibly adapt to different size sound insulation requirements.

The reinforcing component includes a fixed plate, a T-shaped hinge seat, and a Z-shaped clamping plate. The fixed plate and the snap-fit ​​groove are located on the same side. The T-shaped hinge seat is connected to the fixed plate. The two Z-shaped clamping plates are symmetrically arranged and are respectively hinged to the upper and lower ends of the side of the T-shaped hinge seat away from the fixed plate, and clamped to the telescopic rod by fasteners.

[0007] Preferably, the telescopic rod includes a fixed part, two telescopic parts, and two plug-in tubes; the two telescopic parts are respectively connected to the two ends of the fixed part; the ends of the two telescopic parts away from the fixed part are respectively slidably inserted into the two plug-in tubes; the ends of the plug-in tubes away from the telescopic parts are connected to the connecting seat; multiple adjustment holes are equally spaced along the length direction on the telescopic parts, and an adjustment bolt that locks with the adjustment hole is provided on the side wall of the plug-in tube near the telescopic part.

[0008] Preferably, the connecting sleeve further includes four first fastening bolts, and the connecting sleeve is a hollow rectangular structure with open ends; a through hole is opened through each side wall of the connecting sleeve; a first threaded hole corresponding to the through hole is opened on the side wall of the column; a placement groove communicating with the through hole is opened on the connecting seat; the first fastening bolt passes through the placement groove and the through hole and is threadedly connected to the first threaded hole, and the nut of the first fastening bolt is located in the placement groove.

Detailed Implementation

[0025] To better understand the purpose, structure, and function of this utility model, the following detailed description of the gas turbine inlet sound barrier adjustment bracket provided by this utility model is given in conjunction with the accompanying drawings, so that those skilled in the art can better understand this utility model and implement it. However, the embodiments given are not intended to limit this utility model.

[0026] Please see Figures 1 to 7 As shown in the embodiment of this application, a gas turbine inlet sound barrier adjustment bracket is provided, including at least two columns 10 and at least two longitudinally arranged telescopic rods 20; the at least two telescopic rods 20 are respectively located between the two columns 10, and each telescopic rod 20 has a connecting sleeve 30 connected to both ends, the connecting sleeve 30 being detachably sleeved on the outside of the column 10; a connecting seat 31 is respectively provided on the four outer side walls of the connecting sleeve 30; the connecting seat 31 of the connecting sleeve 30 located on the side close to each other between the two columns 10 is connected to the telescopic rod 20, and a snap-fit ​​member 40 for engaging with the sound insulation plate 60 is connected to the connecting seat 31 of the connecting sleeve 30 on the side close to the sound insulation plate 60; the snap-fit ​​member 40 includes a mounting plate 41, a connecting plate 42, and a snap-fit ​​groove 43; the mounting plate 41 is connected to the connecting seat 31; the snap-fit ​​groove 43 is connected to the mounting plate 41 through the connecting plate 42. A base 12 is provided at the bottom of the column 10. The sound insulation panel 60 is provided with a locking block that matches the locking groove 43. The sound insulation panel 60 is connected to the locking groove 43 by the locking block, so as to realize the quick assembly and disassembly of the sound insulation panel 60.

[0027] Because it is equipped with columns 10 and telescopic rods 20, and each end of the telescopic rod 20 is connected to a connecting sleeve 30, the connecting sleeve 30 is equipped with a connecting seat 31, and the connecting seat 31 is equipped with a snap-fit ​​component 40. The snap-fit ​​component 40 includes a mounting plate 41, a connecting plate 42, and a snap-fit ​​groove 43. Through the cooperation of the above components, not only can a sound barrier of the required shape be spliced ​​according to the actual site requirements, but also the sound insulation requirements of different specifications of gas turbine air inlets can be met by changing the width or length of the sound barrier. This effectively solves the technical problem that the traditional gas turbine air inlet sound barrier bracket has a fixed length and cannot flexibly adapt to different sizes of sound insulation requirements. At the same time, it can also realize the quick assembly and disassembly of the sound insulation panel 60, improving the efficiency of sound barrier assembly, disassembly, and maintenance.

[0028] Specifically, by fitting a connecting sleeve 30 onto the column 10 and providing connecting seats 31 on the four outer side walls of the connecting sleeve 30, the column 10 can be connected to different telescopic rods 20 from multiple sides to splice or enclose the required sound insulation bracket, such as forming a straight sound insulation bracket, an L-shaped sound insulation bracket, or a rectangular sound insulation bracket. Furthermore, by setting different numbers of columns 10, the length or width of the gas turbine inlet sound barrier adjustment bracket can be changed. By setting at least two telescopic rods 20 between two columns 10, the connection stability between the two columns 10 can be improved, providing stable support for the sound insulation panel 60. Moreover, by adjusting the length of the telescopic rods 20, the distance between the two columns 10 can be extended or shortened, allowing for fine-tuning of the gas turbine inlet sound barrier adjustment bracket in the length or width direction to meet the sound insulation requirements of the gas turbine inlet. Meanwhile, by installing a snap-fit ​​component 40 on the connecting seat 31 near the sound insulation panel 60 of the connecting sleeve 30, and setting a snap-fit ​​groove 43 on the snap-fit ​​component 40, the mounting plate 41 can be spliced ​​or cut to the corresponding size according to the adjusted size of the gas turbine inlet sound barrier adjustment bracket. When installing the sound insulation panel 60, simply insert the snap-fit ​​block on the sound insulation panel 60 into the snap-fit ​​groove 43 to complete the installation. The operation is simple and convenient, greatly improving the installation efficiency of the sound barrier.

[0029] In a preferred embodiment, the connecting sleeve 30 further includes four first fastening bolts 32, and the connecting sleeve 30 is a hollow rectangular structure with openings at both ends; a through hole 33 is provided through each side wall of the connecting sleeve 30; a first threaded hole 11 corresponding to the through hole 33 is provided on the side wall of the column 10; a placement groove 31a communicating with the through hole 33 is provided on the connecting seat 31; the first fastening bolt 32 passes through the placement groove 31a and the through hole 33 and is threadedly connected to the first threaded hole 11, and the nut of the first fastening bolt 32 is located in the placement groove 31a. A second threaded hole 31b is provided at each of the four corners of the connecting seat 31, and a second fastening bolt 41a threadedly connected to the second threaded hole 31b is provided on the mounting plate 41. The mounting plate 41 is detachably connected to the second threaded hole 31b through the second fastening bolt 41a, so that the snap-fit ​​member 40 can be mounted on the appropriate connecting seat 31 for engaging with the sound insulation plate 60.

[0030] Since the connecting sleeve 30 is provided with a first fastening bolt 32, and each side wall of the connecting sleeve 30 is provided with a through hole 33, the side wall of the column 10 is provided with a first threaded hole 11 corresponding to the through hole 33, and the connecting seat 31 is provided with a placement groove 31a communicating with the through hole 33, through the cooperation between the above components, the connecting sleeve 30 can be fixed to the column 10 by the first fastening bolt 32, and the nut of the first fastening bolt 32 after locking can be placed in the placement groove 31a. While avoiding hindering the connection between the connecting seat 31 and the mounting plate 41, the structure of the connecting sleeve 30 is more concise and beautiful.

[0031] In a preferred embodiment, the telescopic rod 20 is detachably provided with a reinforcing component 50 for reinforcing the sound insulation panel 60. The reinforcing component 50 includes a fixing plate 51, a T-shaped hinge seat 52, and a Z-shaped clamping plate 53. The fixing plate 51 and the snap-fit ​​groove 43 are located on the same side. The T-shaped hinge seat 52 is connected to the fixing plate 51. The two Z-shaped clamping plates 53 are arranged symmetrically to each other, and are respectively hinged to the upper and lower ends of the side of the T-shaped hinge seat 52 away from the fixing plate 51, and are clamped to the fixing part 21 of the telescopic rod 20 by fasteners 54.

[0032] Because the telescopic rod 20 is detachably equipped with a reinforcing component 50, and the reinforcing component 50 is equipped with a fixing plate 51, a T-shaped hinge seat 52 and a Z-shaped clamping plate 53, the cooperation between the above components can not only effectively reinforce the installed sound insulation plate 60 and improve the connection stability between the sound insulation plate 60 and the gas turbine inlet sound barrier adjustment bracket, but also facilitate the disassembly and assembly and position adjustment of the reinforcing component 50, thereby improving the disassembly and assembly efficiency and adaptability of the reinforcing component 50.

[0033] Specifically, a fixing plate 51 is provided for fixed connection with the sound insulation panel 60. Mounting holes are provided at the four corners of the fixing plate 51, allowing it to be fixedly connected to the sound insulation panel 60 or its mounting bracket using screws or bolts. A T-shaped hinge seat 52 is provided to hinge with two Z-shaped clamping plates 53, allowing the two Z-shaped clamping plates 53 to rotate around the hinge seat in directions towards or away from each other. Multiple fastening holes are provided at the end of the Z-shaped clamping plate 53 away from the T-shaped hinge seat 52, allowing the reinforcing component 50 to be fixedly clamped onto the fixing part 21 of the telescopic rod 20 using fasteners 54. The fasteners 54 can be used to lock the bolts and nuts in place. In this embodiment, three telescopic rods 20 are connected between the two columns 10. This improves the stability between the two columns 10, and by providing a reinforcing component 50 on each telescopic rod 20 and connecting the reinforcing component 50 to the sound insulation panel 60 via its fixing plate 51, the stability of the sound insulation panel 60 can be greatly improved.

[0034] In a preferred embodiment, the telescopic rod 20 includes a fixed part 21, two telescopic parts 22, and two plug-in tubes 23; the two telescopic parts 22 are respectively connected to the two ends of the fixed part 21; the ends of the two telescopic parts 22 away from the fixed part 21 are respectively slidably inserted into the two plug-in tubes 23; the ends of the plug-in tubes 23 away from the telescopic parts 22 are connected to the connecting seat 31; a plurality of adjustment holes 22a are equally spaced along the length direction on the telescopic parts 22, and an adjustment bolt 23a that locks with the adjustment hole 22a is provided on the side wall of the plug-in tube 23 near the telescopic part 22.

[0035] Since the telescopic rod 20 is provided with a fixed part 21, two telescopic parts 22 and two plug-in tubes 23, and the telescopic parts 22 are provided with multiple adjustment holes 22a, and the plug-in tubes 23 are provided with adjustment bolts 23a that lock into the adjustment holes 22a, the cooperation between the above components not only allows the length of the telescopic rod 20 to be adjusted to change the distance between the two columns 10, but also ensures that the length of the telescopic rod 20 remains unchanged after adjustment, thereby improving the stability of the telescopic rod 20 and thus improving the connection stability between it and the two columns 10.

[0036] Specifically, the insertion sleeve 23 is designed not only for insertion and engagement with the telescopic part 22, but also for fixed connection with the connecting seat 31. The insertion sleeve 23 is a hollow structure with one open end and one closed end. The telescopic part 22 is inserted into the insertion sleeve 23 through the open end. The longer the telescopic part 22 is inserted into the insertion sleeve 23, the shorter the overall length of the telescopic rod 20. Conversely, the shorter the length of the telescopic part 22 inserted into the insertion sleeve 23, the longer the overall length of the telescopic rod 20. This allows for length adjustment of the telescopic rod 20. Furthermore, the length of the telescopic part 22 inserted into the insertion sleeve 23 is limited and fixed by the use of the adjusting bolt 23a and the adjusting hole 22a.

[0037] In this embodiment, the adjustable bracket for a gas turbine inlet sound barrier is used by first fixing the connecting sleeve 30 to the column 10, and then connecting both ends of the telescopic rod 20 to the connecting seats 31 on the two columns 10 that are close to each other. When there are three or more columns 10, the telescopic rod 20 can be connected to the appropriate connecting seat 31 according to the needs of the sound insulation scenario, so as to form a straight sound insulation bracket with the ends connected, or to form a sound insulation bracket with right-angle corners. After adjusting the length of the telescopic rod 20 and making minor adjustments to the length or width of the adjustable bracket for the gas turbine inlet sound barrier, the base 12 of the column 10 is fixed to the ground. Finally, the sound insulation plate 60 is hung on the slot of the snap-fit ​​component 40, and the reinforcing component 50 is installed on the fixing part 21 of the telescopic rod 20 and adjusted to a suitable position. Then, the fixing plate 51 is fixedly connected to the sound insulation plate 60 to complete the installation of the sound insulation plate 60.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
