Suspended hydro-turbine generators are commonly found in hydroelectric power stations, especially in mountainous areas and areas with abundant rivers.

[0003] The invention with announcement number CN115026070A discloses an integrated integrated generator brake dust removal device, which is composed of a dust collector, a brake pier, an air duct clamp joint, and a metal flame-retardant hose. The brake pier is fixed to an auxiliary force-bearing structure such as an upper frame or a base plate by a fastening device, and the dust collector is mechanically locked to the bottom plate of the brake pier by a fixing fastener and placed in the inner cavity of the brake pier. The utility model avoids lengthy dust suction pipelines, improves the dust suction effect, and extends the unit overhaul and maintenance cycle; it intensively integrates the brake and the brake dust removal device, optimizes the internal space structure of the hydro-turbine generator set, and a single brake pier as a subsystem can operate independently or establish connections with each other. The power station operation and maintenance personnel can simultaneously observe the status data of the brake and the dust collector, and is applicable to large hydro-turbine generator sets and pumped storage units of different structures and sizes.

[0004] Regarding the relevant content mentioned above, the following technical defects exist: the sweeping fan installed on the suspended hydro-turbine generator cannot blow all the generated carbon powder into the dust-proof casing and dust collector of the suspended hydro-turbine generator. Some carbon powder will flow out from the surface of the dust-proof casing, and the temperature inside the suspended hydro-turbine generator and the dust-proof casing will increase with the use time of the suspended hydro-turbine generator. The temperature increase will affect the service life of the filter installed in the dust-proof casing, and will also accelerate the consumption of the service life of the suspended hydro-turbine generator. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that the sweeping fan installed on the suspended hydro-turbine generator cannot blow all the generated carbon powder into the dustproof casing and dust collector of the suspended hydro-turbine generator, part of the carbon powder will flow out from the surface of the dustproof casing, and the temperature inside the suspended hydro-turbine generator and the dustproof casing will increase with the use time of the suspended hydro-turbine generator. The temperature increase will affect the service life of the filter installed in the dustproof casing and accelerate the consumption of the service life of the suspended hydro-turbine generator. Therefore, a dust removal and cooling device for the collector ring of the suspended hydro-turbine generator is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a dust collector and an adjusting device, one side of the dust collector is fixedly connected with a dustproof shell, the inner wall of the dustproof shell is installed with a motor main shaft, the upper surface of the dustproof shell is installed with a sweeping fan, the arc surface of the dustproof shell is provided with an adjusting device, the adjusting device comprises a fixed plate, the fixed plate is fixedly connected to the dustproof shell, one side of the fixed plate is provided with an adjusting groove, the inner wall of the adjusting groove is slidably connected with three adjusting blocks, one side of the adjusting block is fixedly connected with a sliding plate, the side of the sliding plate close to the adjusting block is fixedly connected with a supporting plate, the side of the supporting plate away from the sliding plate is fixedly connected with a limiting plate, the inner wall of the support plate is threaded with a rotating rod, one end of the rotating rod close to the fixed plate is fixedly connected with the limiting block, the side of the sliding plate away from the supporting plate is installed with a load-bearing plate, one side of the load-bearing plate is fixedly connected with a servo motor, and the output end of the servo motor is fixedly connected with a fan blade.

[0007] By adopting the above technical scheme, when the suspended hydro-turbine generator is in use, the carbon powder generated at the collector ring of the motor main shaft during operation cannot be removed in real time, which causes carbon powder accumulation and degradation of the insulation between the positive and negative electrodes, forcing the operating personnel to stop the machine for maintenance. By using a sweeping fan, the carbon powder can be blown into the dust collector through the dustproof shell. The filter installed on the dustproof shell can perform a first filtration on the carbon powder blown into the dust collector. The dust collector will perform a second filtration on the carbon powder that has completed the first filtration. The air generated after filtration will be discharged from the air outlet of the dust collector, but It is impossible to blow all the carbon powder into the dustproof casing and dust collector by the sweeping fan alone. Some carbon powder will flow out from the surface of the dustproof casing, and the temperature inside the motor shaft and the dustproof casing will increase with the use time of the motor shaft. The temperature increase will affect the service life of the filter installed in the dustproof casing and accelerate the consumption of the service life of the motor shaft. At this time, the efficiency of the sweeping fan in removing carbon powder can be improved through the adjustment device, and the temperature inside the motor shaft and the dustproof casing can be reduced through the adjustment device to increase the service life of the motor shaft and the dustproof casing.

The side of the rotating rod 207 close to the limit block 208 is fixedly connected with the abutment block 214. When the rotating rod 207 rotates in the supporting plate 205 and drives the limit block 208 to connect with the dustproof shell 6, the abutment block 214 installed on the limit block 208 can increase the friction between the limit block 208 and the dustproof shell 6, thereby improving the connection effect when the limit block 208 is connected to the dustproof shell 6.

However, when the servo motor 209 and the fan blade 210 fail and cannot continue to work, the user cannot repair the servo motor 209 and the fan blade 210 at a high place without the help of a stepladder, and the safety of repairing with the stepladder is poor. At this time, the auxiliary device 3 can be used to remove the failed servo motor 209 and the fan blade 210 from the dustproof housing 6, so that the failed servo motor 209 and the fan blade 210 can be removed, which can reduce the risk of damage to the failed servo motor 209 and the fan blade. The difficulty of repairing the blade 210 is increased, the repair speed of repairing the servo motor 209 and the fan blade 210 that have a fault is improved, and the repair time is saved. The elastic sheet 34 is fixedly connected to the side away from the fixed frame 31 with an auxiliary block 36. The cross-section of the auxiliary block 36 is arc-shaped.

When the insertion rod 33 needs to be pulled out of the connecting hole 32, the pull ring 37 installed on the insertion rod 33 can be used. The pull ring 37 is used to pull the insertion rod 33 out of the connecting hole 32. The pull rod can increase the speed of pulling the insertion rod 33 in the connecting hole 32, and the surface of the pull ring 37 made of titanium alloy is also relatively hard, which also makes it difficult to find deformation on the surface of the pull ring 37 after long-term use, and has a longer service life.

[0048] The effect achieved by the entire auxiliary device 3 is that when the faulty servo motor 209 and the fan blade 210 need to be repaired, the faulty servo motor 209 and the fan blade 210 on the dustproof housing 6 can be removed from the dustproof housing 6 through the auxiliary device 3, thereby improving the repair effect and speed of repairing the faulty servo motor 209 and the fan blade 210 by disassembling the faulty servo motor 209 and the fan blade 210.

[0049] like Fig. 9 and Fig.10 As shown, the protection device 4 includes a support rod 41, the support rod 41 is fixedly connected to the load-bearing plate 215, the arc surface of the support rod 41 is slidably connected with a sliding block 42, one side of the threaded ring 44 is fixedly connected with a protective frame 43, and one end of the arc surface of the support rod 41 is threadedly connected with a threaded ring 44. When the servo motor 209 drives the fan blade 210 to cool down the dustproof housing 6 and the motor spindle 5, the surface of the fan blade 210 can be protected by the protection device 4, so that the protection device 4 can be used to prevent the fan blade 210 from being damaged when it is bumped by the outside world, affecting the cooling efficiency of the dustproof housing 6 and the motor spindle 5 by the fan blade 210, and at the same time, it can also prevent the user from accidentally touching the surface of the fan blade 210 that is rotating at high speed, avoiding high In order to prevent the fast-rotating fan blades 210 from causing injury to the user, a guide rod 45 is fixedly connected to the end of the support rod 41 away from the load-bearing plate 215, and the guide rod 45 is funnel-shaped. When the threaded ring 44 is used to connect with the support rod 41, the guide rod 45 installed on the support rod 41 can increase the speed at which the threaded ring 44 is connected to the support rod 41, thereby improving the connection efficiency of the threaded ring 44 and the support rod 41 through the guide rod 45. The side of the protective frame 43 away from the load-bearing plate 215 is fixedly connected to an outer frame 46. When the surface of the fan blade 210 is protected by the protective frame 43, the outer frame 46 installed on the protective frame 43 can restrain the wind force generated by the movement of the fan blade 210, thereby improving the cooling effect of cooling the fan blade 210 through the outer frame 46.

[0050] The effect achieved by the entire protective device 4 is that when the fan blade 210 cools down the dustproof housing 6 and the motor spindle 5 through the servo motor 209, the auxiliary device 3 can be installed on the surface of the fan blade 210, so that the surface of the fan blade 210 can be protected by the auxiliary device 3 to avoid damage to the surface of the fan blade 210. At the same time, it can also prevent the user from accidentally touching the fan blade 210 in operation. The auxiliary device 3 can indirectly improve the safety of the use of the fan blade 210.

[0051] The overall working principle is that when it is necessary to improve the dust removal effect of the sweeping fan 7 and reduce the temperature in the motor main shaft 5 and the dustproof housing 6, first adjust the adjustment block 203 in the adjustment slot 202, and the movement of the adjustment block 203 will drive the sliding plate 204 and the support plate 205 to slide along the direction of the fixed plate 201. The movement of the adjustment block 203 drives the servo motor 209 to move through the bearing plate 215. At this time, the position of the fan blade 210 on the fixed plate 201 can be adjusted by the movement of the adjustment block 203. The position is adjusted, and the fan blade 210 is adjusted to a suitable position, and the rotating rod 207 can be rotated in the support plate 205. The rotation of the rotating rod 207 will drive the limit block 208 to connect with the dustproof shell 6, so that it can be connected with the dustproof outside through the limit block 208 to fix the angle of the fan blade 210 on the fixed plate 201. At this time, the private servo motor can be started, and the movement of the servo motor 209 will drive the fan blade 210 to rotate through its output end, so that the fan blade 210 can assist in scanning. The fan 7 performs dust removal, improves the dust removal effect of the sweeping fan 7, and can also cool the motor spindle 5 and the dustproof housing 6. When the adjustment block 203 slides in the adjustment slot 202, the sliding rod 212 slides in the slide slot 213 as the adjustment block 203 slides in the adjustment slot 202. The sliding rod 212 slides in the slide slot 213, which can improve the stability of the adjustment block 203 sliding in the adjustment slot 202. The rotating rod 207 rotates in the support plate 205, driving the limit block When 208 is connected to the dustproof shell 6, the abutment block 214 installed on the limit block 208 can increase the friction force of the connection between the limit block 208 and the dustproof shell 6, thereby improving the connection effect when the limit block 208 is connected to the dustproof shell 6. When it is necessary to rotate the rotating rod 207 in the support plate 205, the rotating rod 207 can be rotated by the disc. The disc can increase the speed of rotating the rotating rod 207 in the support plate 205 and improve the efficiency of rotating the rotating rod 207 in the support plate 205.

[0052] When it is necessary to remove the faulty servo motor 209 and fan blade 210 from the dustproof housing 6, rotate the screw in the plug rod 33 until the screw is rotated out of the plug rod 33. At this time, the plug rod 33 can release the fixed restriction. At this time, the plug rod 33 that has contacted the fixed restriction can be pulled out of the connecting hole 32. At this time, the load-bearing plate 215 is still restricted in the fixed frame 31 under the action of the two elastic sheets 34. The elastic sheets 34 are pressed in the direction away from each other, and the elastic sheets 34 will deform when they move. At this time, the load-bearing plate 215 can be pulled upward and taken out of the fixed frame 31, so that the faulty servo motor 209 and fan blade 210 can be disassembled. Therefore, by disassembling the faulty servo motor 209 and fan blade 210, it is convenient for the user to repair the faulty servo motor 209 and fan blade 210, which assists The device 3 can improve the repair speed and repair effect of the faulty servo motor 209 and the fan blade 210. When the load-bearing plate 215 is clamped with the elastic sheet 34, the auxiliary block 36 can play a guiding role on the elastic sheet 34. Under the action of the auxiliary block 36, the user does not need to manually press the elastic sheet 34 when connecting the load-bearing plate 215 with the elastic sheet 34. The auxiliary block 36 can increase the speed of clamping the load-bearing plate 215 with the elastic sheet 34. When it is necessary to pull the plug rod 33 out of the connecting hole 32, the pull ring 37 installed on the plug rod 33 can be used to pull the plug rod 33 out of the connecting hole 32 through the pull ring 37. The pull rod can increase the speed of pulling the plug rod 33 in the connecting hole 32, and the surface of the pull ring 37 made of titanium alloy is also relatively hard, which also makes it difficult to find deformation on the surface of the pull ring 37 after long-term use, and has a longer service life.

[0053] When the surface of the fan blade 210 needs to be protected by the auxiliary device 3, the sliding block 42 is first connected to the support rod 41 by sliding. At this time, the sliding block 42 can be connected to the support rod 41, and the protective frame 43 can be installed on the arc surface of the support rod 41. At this time, the threaded ring 44 can be rotated on the support rod 41. The threaded ring 44 rotates on the support rod 41 and moves in the direction of the sliding block 42. The threaded ring 44 continues to be rotated until the threaded ring 44 drives the sliding block 42 to abut against the protrusion on the support rod 41 through rotation. The rotation of the threaded ring 44 can be stopped. At this time, the threaded ring 44 can cooperate with the sliding block 42 to abut against the protrusion on the support rod 41. Then, the protective frame 43 can be fixed on the fan blade 210 to complete the installation of the protective frame 43, and the surface of the fan blade 210 can be protected by the protective frame 43. When the threaded ring 44 is connected to the support rod 41, the guide rod 45 installed on the support rod 41 can increase the speed of the connection between the threaded ring 44 and the support rod 41, so that the efficiency of the connection between the threaded ring 44 and the support rod 41 can be improved by the guide rod 45. When the surface of the fan blade 210 is protected by the protective frame 43, the outer frame 46 installed on the protective frame 43 can restrain the wind force generated by the movement of the fan blade 210, so that the outer frame 46 can improve the cooling effect of cooling the fan blade 210.
