DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0025] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0026] like Figure 1 , Figure 2 As shown, a structural diagram of an air intake chamber structure for a gas turbine generator set provided by an embodiment of the present invention includes an air intake chamber body 1, the air intake chamber body 1 is composed of a casing 11 and an air intake cover 12, the air intake cover 12 is fixedly installed at one end of the casing 11, and fixing frames 2 are fixedly installed on both sides of the top of the air intake cover 12, respectively, the fixing frames 2 are rectangular ring-shaped mechanisms, an annular dustproof net 3 is arranged between the two groups of fixing frames 2, a positioning mechanism 4 that cooperates with the dustproof net 3 is arranged in the fixing frame 2, the positioning mechanism 4 includes a supporting assembly 41 and a driving assembly 42, the supporting assembly 41 is located in the fixing frame 2 and is connected to the dustproof net 3, and the supporting assembly 41 is used to control The dust-proof net 3 is in a double-layer horizontal shape and is located at the top of the air inlet hood 12. The driving component 42 is located in the air inlet hood 12 and is connected to the supporting component 41. The driving component 42 controls the dust-proof net 3 to rotate at the top of the air inlet hood 12 by cooperating with the supporting component 41. The inner cavity of the fixed frame 2 is provided with a dust removal mechanism 7 that cooperates with the dust-proof net 3. The dust removal mechanism 7 includes a cleaning component 71 and a purge component 72. The cleaning component 71 is located in the fixed frame 2 and is located on both sides of the dust-proof net 3. The cleaning component 71 is used to clean dust and impurities attached to the surface of the dust-proof net 3. The purge component 72 is located at the top of the air inlet hood 12, and the purge component 72 is used to speed up the air flow speed in the inner cavity of the fixed frame 2.

[0027] The support assembly 41 cooperates with the fixing frame 2 to support and position the dust net 3 at the top of the air inlet hood 12, and the lowest point of the dust net 3 fits with the top of the air inlet hood 12. When the air inlet chamber body 1 is in operation, the high-speed air flows through the dust net 3 and passes through the air inlet hood 12 and the housing 11 in turn. The dust net 3 can filter the dust impurities mixed in the air, and the dust impurities after filtering are attached to the surface of the dust net 3. When the air flows at a high speed in the air inlet hood 12, the drive assembly 42 cooperates with the support assembly 41 to control the dust net 3 to rotate continuously at the top of the air inlet hood 12. When the dust net 3 rotates, different areas of the dust net 3 can be replaced to filter the dust impurities in the air in turn. When the dustproof net 3 is rotating, the cleaning component 71 can clean the dust and impurities attached to the surface of the dustproof net 3 in the inner cavity of the fixed frame 2. While cleaning the dust and impurities, the blowing component 72 can accelerate the movement of air in the inner cavity of the fixed frame 2. The air in the inner cavity of the fixed frame 2 flows from the middle to the outside, and the cleaned dust and impurities can be automatically blown to the outside of the fixed frame 2.

[0028] like Figure 2 , Figure 3 As shown, as a preferred embodiment of the present invention, the support assembly 41 includes a rotating column 411 rotatably installed in the fixed frame 2, a bearing roller 412 is fixedly installed on the surface of the rotating column 411, and the dustproof net 3 is sleeved between two groups of bearing rollers 412.

[0029] The rotating column 411 supports and positions the bearing roller 412 in the inner cavity of the fixed frame 2, and the two groups of bearing rollers 412 support and position the dustproof net 3. When in use, when the air flows at a high speed in the air inlet hood 12, the driving component 42 controls a group of rotating columns 411 to rotate in the inner cavity of the fixed frame 2, and the rotating columns 411 drive the bearing rollers 412 to rotate synchronously. The two groups of bearing rollers 412 cooperate with each other to drive the dustproof net 3 to rotate continuously at the top of the air inlet hood 12.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7As shown, as a preferred embodiment of the present invention, the driving component 42 includes a load-bearing shaft 421 rotatably installed in the inner cavity of the air inlet hood 12, and a plurality of groups of blades 422 distributed in an annular manner are fixedly installed on the surface of the load-bearing shaft 421. A wind shield 423 located on the outside of the blades 422 is rotatably installed in the inner cavity of the air inlet hood 12, and the wind shield 423 is an arc-shaped structure. The two ends of the load-bearing shaft 421 and the rotating column 411 extend to the outside of the air inlet hood 12 and the fixed frame 2 respectively, and synchronous disks 424 are fixedly installed at both ends of the load-bearing shaft 421 and the rotating column 411 respectively. The two groups of synchronous disks 424 are commonly connected with a synchronous belt 425. An adjustment component 5 that cooperates with the wind shield 423 is provided in the air inlet hood 12, and the adjustment component 5 is used to adjust the position angle of the wind shield 423.

[0031] The adjusting component 5 positions the wind shield 423 in the inner cavity of the air inlet hood 12. When the wind shield 423 is on the right side of the blade 422, the wind shield 423 blocks the blade 422 on the outer half of the bearing shaft 421. When the air flows at a high speed in the air inlet hood 12, the air blows the blade 422 on the other half of the outer side of the bearing shaft 421 to rotate. The multiple groups of blades 422 cooperate with each other to drive the bearing shaft 421 to rotate. The bearing shaft 421 drives the synchronous disk 424 to rotate. The two groups of synchronous disks 424 and the synchronous belt 425 cooperate with each other to drive the rotating column 411 to rotate. When it is not necessary to clean the surface of the dustproof net 3, the adjusting component 5 adjusts the position of the wind shield 423 so that the wind shield 423 rotates to the top of the blade 422. At this time, the wind shield 423 can block the high-speed air flowing in the inner cavity of the air inlet hood 12, and the blade 422 below the wind shield 423 remains stationary and does not rotate.

[0032] like Figure 5 , Figure 6 , Figure 7 As shown, as a preferred embodiment of the present invention, the adjustment component 5 includes an arc-shaped rack 51 arranged on the surface of the wind shield 423, a control rod 52 is rotatably installed in the inner cavity of the air inlet cover 12, a control gear disk 53 is fixedly installed on the surface of the control rod 52, the control gear disk 53 is meshingly connected with the rack 51, one end of the control rod 52 extends to the outside of the air inlet cover 12 and a control disk 54 is fixedly installed thereon, and a side wall of the air inlet cover 12 is provided with a limiter 6 that cooperates with the control disk 54.

[0033] When the position of the wind shield 423 needs to be adjusted, the limit member 6 releases the restriction on the control disk 54, and the staff holds the control disk 54 and rotates it. The control disk 54 drives the control rod 52 to rotate, and the control rod 52 drives the control gear plate 53 to rotate in the air inlet cover 12. The control gear plate 53 engages with the rack 51 for transmission, which can drive the wind shield 423 to rotate in the air inlet cover 12. After the wind shield 423 rotates to a suitable position, the limit member 6 fixes the position of the control disk 54 at the side wall of the air inlet cover 12.

[0034] like Figure 1 , Figure 5 , Figure 6 As shown, as a preferred embodiment of the present invention, the limit member 6 includes a plurality of groups of annular and evenly spaced snap-in holes 61 opened on the surface of the control disk 54, and a snap-in rod 62 cooperating with the snap-in holes 61 is rotatably mounted on the side wall of the air inlet cover 12.

[0035] Initially, the clamping rod 62 is inserted into the clamping hole 61. At this time, the control panel 54 is fixedly installed on the side wall of the air inlet cover 12. When the position of the wind shield 423 needs to be adjusted, the clamping rod 62 is rotated to separate the clamping rod 62 and the clamping hole 61 from each other. At this time, the control panel 54 can be easily rotated to adjust the position of the wind shield 423.

[0036] like Figure 2 , Figure 3 , Figure 8 As shown, as a preferred embodiment of the present invention, the cleaning component 71 includes two groups of cleaning rods 711 rotatably installed in the inner cavity of the fixed frame 2, which are respectively located on both sides of the dustproof net 3, and the surface of the cleaning rod 711 is provided with multiple groups of evenly distributed brushes 712. The surfaces of the cleaning rod 711 and the rotating column 411 are respectively fixedly installed with synchronous gear plates 713, and the multiple groups of synchronous gear plates 713 are commonly connected with a synchronous toothed belt 714.

[0037] When rotating, the rotating column 411 drives the synchronous gear plate 713 to rotate. The multiple sets of synchronous gear plates 713 cooperate with the synchronous toothed belt 714 to drive the two sets of cleaning rods 711 to rotate synchronously in the inner cavity of the fixed frame 2. The cleaning rods 711 drive the multiple sets of brushes 712 to rotate on both sides of the dustproof net 3 respectively. The brushes 712 can clean the dust and impurities attached to the surface of the dustproof net 3 in all directions.

[0038] like Figure 1 , Figure 2 , Figure 4 , Figure 8As shown, as a preferred embodiment of the present invention, the purge assembly 72 includes a plurality of bracket groups 721 respectively fixedly installed on both sides of the air inlet cover 12, and the plurality of bracket groups 721 are jointly fixedly installed with a sealing ring 722 located at the top of the air inlet cover 12, and the sealing ring 722 is located in the dustproof net 3, and the sealing ring 722 is respectively provided with blowing ports 723 on both side walls facing the fixed frame 2, and an air guide plate 724 is fixedly installed in the air outlet 723, and the air guide plate 724 is inclined and extends to the inner cavity of the sealing ring 722.

[0039] When the air flows at high speed in the sealing ring 722 and the air inlet cover 12, the air guide plate 724 guides a small part of the air, and part of the air passes through the air outlet 723 along the air guide plate 724 and then blows into the inner cavity of the fixing frame 2. When the air flows in the inner cavity of the fixing frame 2, the dust and impurities cleaned from the surface of the dustproof net 3 can be easily blown to the outside of the fixing frame 2.

[0040] like Figure 5 , Figure 7 As shown, as a preferred embodiment of the present invention, two opposite inner side walls of the air inlet cover 12 are respectively provided with arc-shaped guide grooves 8, and both ends of the wind shield 423 are rotatably installed in the guide grooves 8.

[0041] The working principle of the present invention is: two groups of supporting rollers 412 support and position the dustproof net 3. When the air intake chamber main body 1 is in operation, the high-speed flowing air passes through the dustproof net 3 and passes through the air inlet cover 12 and the casing 11 in turn. The dustproof net 3 can screen and filter the dust impurities mixed in the air, and the dust impurities after screening and filtration adhere to the surface of the dustproof net 3. The wind shield 423 is on the right side of the blade 422. At this time, the wind shield 423 blocks the blade 422 on the outer half of the bearing shaft 421. When the air flows at a high speed in the air inlet cover 12, the air blows the blade 422 on the other half of the outer side of the bearing shaft 421 to rotate. The multiple groups of blades 422 cooperate with each other to drive the bearing shaft 421 to rotate. The bearing shaft 421 drives the synchronous disk 424 to rotate. The two groups of synchronous disks 424 and the synchronous belt 425 cooperate with each other to drive the rotating column 411 to rotate. The rotating column 411 drives the bearing roller 412 to rotate synchronously. The two groups of bearing rollers 412 cooperate with each other to drive the dust net 3 to rotate continuously at the top of the air inlet cover 12. When the dust net 3 rotates, different areas of the dust net 3 can be replaced to filter dust impurities in the air in turn.

[0042] The rotating column 411 drives the synchronous toothed disc 713 to rotate when rotating. The multiple sets of synchronous toothed discs 713 cooperate with the synchronous toothed belt 714 to drive the two sets of cleaning rods 711 to rotate synchronously in the inner cavity of the fixed frame 2. The cleaning rods 711 drive the multiple sets of brushes 712 to rotate on both sides of the dustproof net 3 respectively. The brushes 712 can perform all-round cleaning of dust and impurities attached to the surface of the dustproof net 3. When the air flows at a high speed in the sealing ring 722 and the air inlet cover 12, the air guide plate 724 guides a small part of the air, and a part of the air passes through the air outlet 723 along the air guide plate 724 and then blows to the inner cavity of the fixed frame 2. When the air flows in the inner cavity of the fixed frame 2, the dust and impurities cleaned from the surface of the dustproof net 3 can be easily blown to the outside of the fixed frame 2.

[0043] When there is no need to clean the surface of the dustproof net 3, the staff holds the control disk 54 and rotates it, and the control disk 54 drives the control rod 52 to rotate, and the control rod 52 drives the control gear plate 53 to rotate in the air inlet cover 12. The control gear plate 53 engages with the rack 51 for transmission, which can drive the wind shield 423 to rotate in the air inlet cover 12, so that the wind shield 423 rotates above the blades 422. At this time, the wind shield 423 can block the high-speed air flowing in the inner cavity of the air inlet cover 12, and the blades 422 under the wind shield 423 remain stationary and do not rotate.

[0044] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
