A stable water turbine unit bearing bush for a hydropower station

Abstract

This invention discloses a stable bearing for hydropower units, comprising a bearing body, a limiting assembly, and a heat dissipation assembly. The inner wall of the bearing body has multiple sets of No. 1 oil grooves. The inner wall of the limiting assembly is fitted with a threaded ring. A limiting block is fixedly installed on the outer wall of the No. 2 connecting frame. A slip ring is installed on the outer wall of the drive plate. This invention improves the stability of the bearing installation by installing the limiting assembly. After the bearing is installed inside the support, rotating the bolts moves the drive plate. This movement of the drive plate moves the No. 1 connecting frame, which in turn moves the No. 2 connecting frame via the connecting plate. This movement of the No. 2 connecting frame pushes the limiting block out of the limiting assembly. When one end of the limiting block contacts the inner wall of the hydropower unit where the bearing is installed, the stability of the bearing installation is improved, thus achieving the goal of enhancing bearing installation stability.

Description

Technical Field

[0001] This invention relates to the field of bearing technology, specifically to a stable type of bearing for hydroelectric generator units used in hydropower stations. Background Technology

[0002] The bearing bush is the part of a sliding bearing that contacts the journal. It is a semi-cylindrical surface shaped like a tile, and is very smooth. It is generally made of wear-resistant materials such as bronze and anti-friction alloys. There are two types of bearing bushes: integral and split. Integral bearing bushes are usually called bushings. Integral bearing bushes are available in oil-grooved and oil-grooved varieties. In hydroelectric power stations, bearing bushes are used to assist the rotation of the turbine generator when it is generating electricity, thereby converting the kinetic energy generated by the water flow into electrical energy. If the bearing bushes of existing hydroelectric power units wobble after installation, it will affect the normal operation of the hydroelectric power unit. To address this, we have proposed a stable bearing bush for hydroelectric power stations, which can improve the stability of bearing bush installation and prevent the bearing bush wobble from affecting the normal operation of the hydroelectric power unit.

[0003] The existing bearing bushes have the following defects:

[0004] 1. Patent document CN102900767A discloses a bearing bush, "composed of a steel backing layer, an aluminum alloy base layer, and a friction-reducing layer, wherein the aluminum alloy base layer is disposed on the steel backing layer, and the friction-reducing layer is disposed on the aluminum alloy base layer, characterized in that: the aluminum alloy base layer is composed of a tin-aluminum alloy; the friction-reducing layer is composed of nickel, molybdenum disulfide, polyimide, and graphite. This invention has the advantages of good friction reduction, high temperature resistance, corrosion resistance, high strength, and environmental friendliness." However, the bearing bush disclosed in the above-mentioned document mainly considers improving the strength of the bearing bush, without considering the issue of improving the installation stability of the bearing bush. Therefore, it is necessary to study a structure that can improve the installation stability of the bearing bush, thereby preventing the bearing bush from shaking and affecting the normal operation of the hydropower unit.

[0005] 2. Patent document CN107448478A discloses an environmentally friendly bearing bush, "comprising two opposing bearing bush bodies. Each bearing bush body has a semi-circular connecting ring fixedly fitted at both ends. Multiple bolt connection ports are equidistantly arranged on the connecting rings. A semi-circular fixing ring is provided between the two connecting rings, and the fixing ring is fixedly fitted onto the bearing bush body. An adjusting ring is provided between the fixing ring and one of the connecting rings. The adjusting ring is rotatably fitted onto the two bearing bush bodies. A locking ring is provided on the side of the adjusting ring away from the fixing ring, and the locking ring is threaded onto the two bearing bush bodies. The adjusting ring is closer to..." A ring-shaped contact groove is provided on one side of the fixed ring, and multiple connecting shafts are rotatably connected to the fixed ring. This invention has a simple structure and is easy to use. The contact area and pressure between the bearing bush and the journal are easily adjustable, thereby adjusting the friction between the bearing bush and the journal, facilitating lubrication while preventing bearing bush burnout. However, the aforementioned environmentally friendly bearing bush mainly considers adjusting the contact area and pressure between the bearing bush and the journal, without considering improving the bearing bush's heat dissipation efficiency. Therefore, it is necessary to research a structure that can improve the heat dissipation efficiency of the bearing bush, thereby extending the service life of bearing bushes used in hydropower units.

[0006] 3. Patent document CN207554582U discloses a wear-resistant bearing bush, "including a shell, characterized in that: an inner shell is provided inside the shell, the outer surface of the inner shell is attached to the inner surface of the shell, a plurality of dovetail protrusions are provided on the inner surface of the shell, a plurality of dovetail grooves are provided on the outer surface of the inner shell, the dovetail protrusions are fitted into the dovetail grooves with a movable allowance, and an elastic plate is provided in the gap between the dovetail protrusions and the dovetail grooves; a wear-resistant inner lining layer is provided inside the inner shell, a plurality of recesses are formed on the wear-resistant inner lining layer, and graphene blocks are embedded in the recesses. This utility model provides a wear-resistant bearing bush with simple structure, high strength, safety and practicality, low friction coefficient and long service life." However, the wear-resistant bearing bush disclosed in the above-mentioned document mainly considers extending the wear-resistant service life and does not consider the problem of rapid lubrication. Therefore, it is necessary to study a structure that can quickly lubricate the bearing bush, thereby preventing the bearing bush from increasing the friction between the hydroelectric generator shaft.

[0007] 4. Patent document CN206845693U discloses a combined bearing bush, "The bearing bush includes an outer bearing body and an inner bearing body; the inner wall of the outer bearing body is provided with a groove, and the outer bearing body is annular; the inner bearing body includes at least two tiles, and the outer side of each tile is provided with a retaining strip corresponding to the groove position. The tiles are sequentially connected to the inner wall of the outer bearing body through the retaining strip and the groove structure, and the tiles form an annular shape that fits against the inner wall of the outer bearing body; the cross-section of the groove is an isosceles trapezoid, the cross-section of the retaining strip is an isosceles trapezoid, and a gap is reserved between the groove and the retaining strip; the tiles in..." The inner bearing has an internal oil injection hole, and the outer bearing body has an external oil injection hole corresponding to the internal oil injection hole. This utility model offers convenient and quick assembly, provides sufficient lubrication during use, allows for individual bearing replacement, saves resources, and has a long service life. However, the aforementioned published composite bearing mainly considers the ability to replace individual bearings and save resources, without addressing the issue of preventing external impurities from entering the bearing's interior. Therefore, it is necessary to research a bearing that can prevent large external objects from entering the interior, thereby improving the sealing performance of bearings used in hydroelectric generator sets. Summary of the Invention

[0015] Preferably, one end of the threaded ring is fixedly connected to the inner wall of the limiting component, the first ring and the second ring are symmetrically installed at both ends of the bearing body, one end of the guide frame extends into the interior of the limiting block to guide the limiting block, the heat dissipation component is embedded in the interior of the bearing body to dissipate heat from the bearing body, and the connecting pipe is installed on the outer wall of the ventilation slot to connect multiple sets of ventilation slots.

[0016] Preferably, a lubrication assembly is installed on the inner wall of the bearing body, an oil inlet pipe is installed on the inner wall of the lubrication assembly, an oil supply groove is installed on the inner wall of the lubrication assembly, and one end of the oil inlet pipe extends into the interior of the oil supply groove. Multiple sets of liquid storage tanks are installed on both outer walls of the oil supply groove. Oil-absorbing cotton is installed on the inner wall of the liquid storage tank, and a drain pipe is installed on the outer wall of the liquid storage tank, with one end of the drain pipe extending into the interior of the first oil tank. A threaded sleeve is installed on the inner wall of the lubrication assembly, a threaded screw is installed on the inner wall of the threaded sleeve, a drive frame is installed at the bottom of the threaded screw, multiple sets of rods are installed through the inner wall of the drive frame, and a pressure plate is installed at the bottom of the drive frame, with the pressure plate located above the oil-absorbing cotton.

[0017] Preferably, the inner wall of the bearing body is symmetrically provided with two sets of mounting grooves, the inner wall of the mounting groove is provided with a fixing plate, the outer wall of the fixing plate is provided with a rubber airbag, the outer wall of the rubber airbag is surrounded by multiple sets of plates, and the outer wall of the plates is provided with lubrication blocks.

[0018] Preferably, an air supply pipe is installed on the outer wall of the rubber airbag.

[0019] Preferably, the working steps of the hydroelectric generator bearing are as follows:

[0020] S1. Firstly, when installing and using the bearing bushes of the hydropower generator units used in the hydropower station, after installing the bearing bushes inside the support, rotate the bolt and threaded ring to move the bolt position. One end of the bolt is movably connected to the No. 1 connecting piece. When the bolt moves, it can push the drive plate to move. When the drive plate moves, it drives the No. 1 connecting frame to move. When the No. 1 connecting frame moves, it pushes the No. 2 connecting frame to move through the connecting plate. When the No. 2 connecting frame moves, it pushes the limit block to move out of the limit assembly. After one end of the limit block contacts the inner wall of the hydropower generator unit where the bearing bushes are installed, it can improve the stability of the bearing bush installation and achieve the purpose of improving the stability of the bearing bush installation. It can effectively prevent the bearing bush position from shaking and affecting the normal operation of the hydropower generator unit.

[0021] S2. After prolonged operation, the bearings of hydropower units in hydroelectric power stations generate high temperatures. To extend the service life of the bearings, the heat from the bearing body itself is transferred to the interior of the heat-conducting plate. The power supply components provide energy for the operation of the micro fan. The micro fan generates wind power, which flows into the interior of the ventilation slot through the air inlet pipe. The connecting pipe allows the wind power to flow inside multiple ventilation slots. The ventilation slots are in close contact with the outer wall of the heat-conducting plate. When the wind power flows inside the ventilation slots, it can dissipate the heat absorbed by the heat-conducting plate. The hot air enters the interior of the exhaust head through the exhaust pipe, and the wind power is transmitted to the outside through the exhaust head. This can improve the heat dissipation efficiency of the bearings, achieve the purpose of rapid heat dissipation of the bearings, and extend the service life of the bearings used in hydropower units.

[0022] S3. After prolonged use, when the bearing bushes of the hydroelectric generator experience significant friction with the internal shaft, lubricating oil is added to the oil supply tank through the oil inlet pipe. As the lubricating oil flows within the oil supply tank, it enters the storage tank for storage. Oil-absorbing cotton absorbs the lubricating oil. To add lubricating oil to the inside of the bearing bush, rotate the threaded screw. The bottom end of the threaded screw is movably connected to the drive frame. The threaded sleeve moves the threaded screw, pushing the drive frame to move vertically along the outer wall of the rod. This movement of the drive frame moves the pressure plate. When the pressure plate moves, it squeezes the oil-absorbing cotton inside the storage tank, causing the lubricating oil absorbed by the cotton to be squeezed out. The lubricating oil will flow into the No. 1 oil tank through the drain pipe. When the shaft rotates inside the bearing body, the lubricating oil can be quickly applied to the inside of the bearing body, achieving the purpose of rapid lubrication. After the bearing of the hydro-generator unit has been used for a long time, when the internal friction is too large, the internal lubricating oil can be quickly applied to it, thereby preventing the excessive friction from damaging the hydro-generator unit and extending the service life of the bearing body.

[0023] S4. When sealing is required at the connection between the bearing bush and the shaft of the hydro-generator unit, an external air pump is used to transmit air pressure to the inside of the rubber air bladder through the air supply pipe, causing the rubber air bladder to expand. When the rubber air bladder expands, it drives the plate to move. When the plate moves, it drives the lubrication block to move. After the lubrication block moves to the outer wall of the hydro-generator unit shaft, the external air pump stops working and the air supply pipe is sealed. The plate can block the connection between the hydro-generator unit and the bearing bush, which can effectively prevent external impurities from entering the interior of the bearing bush and affecting the normal use of the bearing bush and the hydro-generator unit. This achieves the purpose of preventing large external impurities from entering the interior of the bearing bush through the gaps in the bearing bush.

[0024] Preferably, step S1 further includes the following steps:

[0025] S11. When the drive plate moves, it drives the slip ring to slide horizontally on the outer wall of the guide shaft, which can guide the drive plate to slide horizontally.

[0026] Step S2 further includes the following steps:

[0027] S21. When the micro fan is working, when the outside air flows into the interior of the No. 1 tank, the filter screen filters the impurities carried in the flowing air.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. This invention improves the stability of the installation of bearing bushes for hydropower units by installing a limiting component. When installing the bearing bushes for hydropower units in hydropower stations, after the bearing bushes are installed inside the support, the bolts and threaded rings are rotated to move the bolts. One end of the bolts is movably connected to the first connecting piece. When the bolts move, they can push the drive plate to move. When the drive plate moves, it drives the first connecting frame to move. When the first connecting frame moves, it pushes the second connecting frame to move through the connecting plate. When the second connecting frame moves, it pushes the limiting block to move out of the limiting component. After one end of the limiting block contacts the inner wall of the hydropower unit where the bearing bushes are installed, the stability of the bearing bush installation can be improved, thus achieving the purpose of improving the stability of the bearing bush installation. This can effectively prevent the bearing bushes from shaking and affecting the normal operation of the hydropower unit.

[0030] 2. This invention improves the heat dissipation efficiency of bearings used in hydropower units by installing heat dissipation components. After prolonged operation, the bearings of hydropower units in hydropower stations generate high temperatures. To extend the service life of the bearings, the heat of the bearing body itself is transferred to the interior of the heat-conducting plate. The power supply component provides energy for the operation of the micro fan, which generates wind power. The wind power flows into the interior of the ventilation slot through the air inlet pipe. The connecting pipe allows the wind power to flow inside multiple ventilation slots. The ventilation slots are in contact with the outer wall of the heat-conducting plate. When the wind power flows inside the ventilation slots, it can dissipate the heat absorbed by the heat-conducting plate. The hot air enters the interior of the exhaust head through the exhaust pipe, and the wind power is transmitted to the outside through the exhaust head. This improves the heat dissipation efficiency of the bearings, achieves the purpose of rapid heat dissipation of the bearings, and can extend the service life of the bearings used in hydropower units.

[0031] 3. This invention, by installing a lubrication component and oil-absorbing cotton, allows for the rapid application of lubricating oil to the interior of the bearing bushes of hydroelectric generator sets. After prolonged use, when the bearing bushes experience significant friction with the internal shaft, lubricating oil is added to the oil supply groove via the oil inlet pipe. As the lubricating oil flows within the oil supply groove, it enters the storage tank for storage. The oil-absorbing cotton absorbs the lubricating oil. When additional lubricating oil needs to be added to the bearing bush body, the threaded screw is rotated. The bottom end of the threaded screw is movably connected to the drive frame. The threaded sleeve moves the threaded screw, which in turn pushes the drive frame to move vertically along the outer wall of the screw body. When the drive frame moves, it moves the pressure plate. When the pressure plate moves, it squeezes the oil-absorbing cotton inside the storage tank, causing the lubricating oil absorbed by the cotton to be squeezed out. The lubricating oil will flow into the No. 1 oil tank through the drain pipe. When the shaft rotates inside the bearing body, the lubricating oil can be quickly applied to the inside of the bearing body, achieving the purpose of rapid lubrication. After the bearing of the hydro-generator unit has been used for a long time, when the internal friction is too large, the internal lubricating oil can be quickly applied to it, thereby preventing the excessive friction from damaging the hydro-generator unit and extending the service life of the bearing body.

[0032] 4. This invention, by installing a rubber airbag and a plate, can effectively prevent large external impurities from entering the interior of the bearing bush. An external air pump is used to transmit air pressure to the interior of the rubber airbag through an air supply pipe, causing the rubber airbag to expand. When the rubber airbag expands, it drives the plate to move. When the plate moves, it drives the lubricating block to move. After the lubricating block moves to the outer wall of the hydroelectric generator shaft, the external air pump stops working and the air supply pipe is sealed. The plate can block the connection between the hydroelectric generator and the bearing bush, effectively preventing external impurities from entering the interior of the bearing bush and affecting the normal use of the bearing bush and the hydroelectric generator. This achieves the purpose of preventing large external impurities from entering the interior of the bearing bush through the gaps. Attached Figure Description

It can effectively prevent the bearing from shaking and affecting the normal operation of the hydro-generator unit.

[0047] Please see Figure 3 and Figure 4The bearing body 1 has multiple sets of heat dissipation components 17. Multiple sets of heat-conducting plates 18 are installed on the inner wall of the heat dissipation components 17. A ventilation slot 21 is fixedly installed on the outer wall of the heat-conducting plates 18. A connecting pipe 20 is installed on the outer wall of the ventilation slot 21. An air inlet pipe 19 is installed on the outer wall of the ventilation slot 21, and the air inlet pipe 19 is located on one side of the connecting pipe 20. An exhaust pipe 22 is installed on the outer wall of the ventilation slot 21. Multiple sets of first-level slots 23 are installed on the inner wall of the first-level ring 3. A miniature fan 24 is installed on the inner wall of the first-level slot 23, and one end of the air inlet pipe 19 extends to the input end of the miniature fan 24.

After long-term operation, the bearing of the hydropower unit in the hydropower station will generate a high temperature. In order to extend the service life of the bearing, the heat of the bearing body 1 itself will be transferred to the interior of the heat conduction plate 18. The power supply component 26 provides energy for the operation of the micro fan 24. The micro fan 24 generates wind power, which flows into the interior of the ventilation slot 21 through the air inlet pipe 19. The connecting pipe 20 allows the wind power to flow inside the multiple ventilation slots 21. The ventilation slots 21 are in contact with the outer wall of the heat conduction plate 18.

[0048] Please see Figure 5 and Figure 6A lubrication assembly 29 is installed on the inner wall of the bearing body 1. An oil inlet pipe 30 is installed on the inner wall of the lubrication assembly 29. An oil supply groove 31 is installed on the inner wall of the lubrication assembly 29, and one end of the oil inlet pipe 30 extends into the interior of the oil supply groove 31. Multiple sets of liquid storage grooves 32 are installed on both outer walls of the oil supply groove 31. Oil-absorbing cotton 33 is installed on the inner wall of the liquid storage groove 32. A drain pipe 34 is installed on the outer wall of the liquid storage groove 32, and one end of the drain pipe 34 extends into the interior of the first oil groove 2. The inner wall of the lubrication assembly 29 is threaded. Sleeve 36, threaded sleeve 36 has a threaded screw 35 installed on its inner wall, drive frame 37 is installed at the bottom of threaded screw 35, multiple rods 38 are installed through the inner wall of drive frame 37, pressure plate 39 is installed at the bottom of drive frame 37 and is located above oil absorbent cotton 33. After long-term use, when the bearing of the hydro-generator unit has large friction with the internal shaft, the lubricating oil to be added is added to the inside of the oil supply groove 31 through oil inlet pipe 30. When the lubricating oil flows inside the oil supply groove 31, it will flow... The lubricating oil is stored inside the storage tank 32. The oil-absorbing cotton 33 absorbs the lubricating oil. When lubricating oil needs to be added to the inside of the bearing body 1, the threaded screw 35 is rotated. The bottom end of the threaded screw 35 is movably connected to the drive frame 37. When the threaded sleeve 36 moves the threaded screw 35, it pushes the drive frame 37 to move vertically on the outer wall of the rod 38. When the drive frame 37 moves, it drives the pressure plate 39 to move. When the pressure plate 39 moves, it squeezes the oil-absorbing cotton 33 inside the storage tank 32, squeezing out the lubricating oil absorbed by the oil-absorbing cotton 33. The lubricating oil will flow into the first oil tank 2 through the drain pipe 34. When the shaft rotates inside the bearing body 1, the lubricating oil can be quickly applied to the inside of the bearing body 1, achieving the purpose of rapid application of lubricating oil. After long-term use of the bearings of the hydro-generator unit, when the internal friction is too high, the internal lubricating oil can be quickly applied to prevent excessive friction from damaging the hydro-generator unit and extend the service life of the bearing body 1.

[0049] Please see Figure 7The inner wall of the bearing body 1 is symmetrically provided with two sets of mounting grooves 40. A fixing plate 41 is installed on the inner wall of the mounting groove 40. A rubber air bladder 42 is installed on the outer wall of the fixing plate 41. Multiple sets of plates 44 are installed around the outer wall of the rubber air bladder 42. Lubrication blocks 45 are installed on the outer wall of the plates 44. An air supply pipe 43 is installed on the outer wall of the rubber air bladder 42. When sealing is required at the connection between the bearing and the shaft of the hydro-generator unit, an external air pump is used to transmit air pressure to the interior of the rubber air bladder 42 through the air supply pipe 43, causing the rubber air bladder 42 to... When the volume of the rubber airbag 42 expands, it drives the plate 44 to move. When the plate 44 moves, it drives the lubricating block 45 to move. After the lubricating block 45 moves to the outer wall of the hydro-generator shaft, the external air pump stops working and at the same time seals the air supply pipe 43. The plate 44 can block the connection between the hydro-generator and the bearing, which can effectively prevent external impurities from entering the interior of the bearing and affecting the normal use of the bearing and the hydro-generator. It achieves the purpose of preventing large external impurities from entering the interior of the bearing through the gaps in the bearing.

[0050] The working steps of the hydroelectric generator's bearing are as follows:

[0051] S1. Firstly, when installing and using the bearing bush of the hydropower unit, after installing the bearing bush inside the support, rotate the bolt 7 and threaded ring 6 to move the bolt 7 to a new position. One end of the bolt 7 is movably connected to the first connecting piece 8. When the bolt 7 moves, it can push the drive plate 9 to move to a new position. When the drive plate 9 moves to a new position, it drives the first connecting frame 12 to move to a new position. When the first connecting frame 12 moves, it pushes the second connecting frame 14 to move to a new position through the connecting plate 13. When the second connecting frame 14 moves, it pushes the limit block 15 to move out of the interior of the limit assembly 5. After one end of the limit block 15 contacts the inner wall of the hydropower unit where the bearing bush is installed, it can improve the stability of the bearing bush installation and achieve the purpose of improving the stability of the bearing bush installation. It can effectively prevent the bearing bush from shaking and affecting the normal operation of the hydropower unit.

[0052] S2. After long-term operation, the bearings of the hydropower units in the hydropower station will generate high temperatures. To extend the service life of the bearings, the heat of the bearing body 1 itself will be transferred to the interior of the heat conduction plate 18. The power supply component 26 provides energy for the operation of the micro fan 24. The micro fan 24 generates wind power, which flows into the interior of the ventilation slot 21 through the air inlet pipe 19. The connecting pipe 20 allows the wind power to flow inside the multiple ventilation slots 21. The ventilation slots 21 are in contact with the outer wall of the heat conduction plate 18. When the wind power flows inside the ventilation slots 21, it can dissipate the heat absorbed by the heat conduction plate 18. The hot air enters the interior of the exhaust head 28 through the exhaust pipe 22. The wind power is transmitted to the outside through the exhaust head 28, thereby improving the heat dissipation efficiency of the bearings and achieving the purpose of rapid heat dissipation of the bearings, which can extend the service life of the bearings used in the hydropower units.

[0053] S3. After prolonged use, when the bearing bush of the hydroelectric generator experiences significant friction with the internal shaft, lubricating oil is added to the oil supply tank 31 via the oil inlet pipe 30. As the lubricating oil flows within the oil supply tank 31, it enters the storage tank 32 for storage. The oil-absorbing cotton 33 absorbs the lubricating oil. When lubricating oil needs to be added to the bearing bush body 1, the threaded screw 35 is rotated. The bottom end of the threaded screw 35 is movably connected to the drive frame 37. When the threaded sleeve 36 moves the threaded screw 35, it pushes the drive frame 37 to move vertically along the outer wall of the rod body 38. The movement of the drive frame 37 drives the pressure plate. When the pressure plate 39 moves, it squeezes the oil-absorbing cotton 33 inside the liquid storage tank 32, causing the lubricating oil absorbed by the oil-absorbing cotton 33 to be squeezed out. The lubricating oil will flow into the interior of the first oil tank 2 through the drain pipe 34. When the shaft rotates inside the bearing body 1, the lubricating oil can be quickly applied to the interior of the bearing body 1 to achieve the purpose of quickly applying the lubricating oil. After the bearing of the hydro-generator unit has been used for a long time, when the internal friction is too large, the internal lubricating oil can be quickly applied to it, thereby preventing the excessive friction from damaging the hydro-generator unit and extending the service life of the bearing body 1.

[0054] S4. When it is necessary to seal the connection between the bearing and the shaft of the hydro-generator unit, an external air pump is used to transmit air pressure to the inside of the rubber air bag 42 through the air supply pipe 43, causing the rubber air bag 42 to expand. When the rubber air bag 42 expands, it drives the plate 44 to move. When the plate 44 moves, it drives the lubrication block 45 to move. After the lubrication block 45 moves to the outer wall of the hydro-generator unit shaft, the external air pump stops working and the air supply pipe 43 is sealed. The plate 44 can block the connection between the hydro-generator unit and the bearing, which can effectively prevent external impurities from entering the inside of the bearing and affecting the normal use of the bearing and the hydro-generator unit. This achieves the purpose of preventing large external impurities from entering the inside of the bearing through the gaps in the bearing.

[0055] Step S1 also includes the following steps:

[0056] S11. When the drive plate 9 moves, it drives the slip ring 10 to slide horizontally on the outer wall of the guide shaft 11, which can guide the drive plate 9 to slide horizontally.

[0057] Step S2 also includes the following steps:

[0058] S21. When the micro fan 24 is working, when the outside air flows into the interior of the first tank 23, the filter screen 25 filters the impurities carried in the flowing air.

[0059] Working principle: First, when installing the bearing bushes of the hydroelectric generator units used in the hydropower station, after the bearing bushes are installed inside the support, the bolt 7 is rotated, and the threaded ring 6 moves the bolt 7. One end of the bolt 7 is movably connected to the first connecting piece 8. When the bolt 7 moves, it can push the drive plate 9 to move. When the drive plate 9 moves, it drives the first connecting frame 12 to move. When the first connecting frame 12 moves, it pushes the second connecting frame 14 to move through the connecting plate 13. When the second connecting frame 14 moves, it pushes the limit block 15 to move out of the limit assembly 5. After one end of the limit block 15 contacts the inner wall of the hydroelectric generator unit where the bearing bushes are installed, it can improve the stability of the bearing bush installation, thereby effectively preventing the bearing bushes from shaking and affecting the installation stability. During normal operation of the hydroelectric generator unit, the bearings of the generator unit in the hydroelectric power station will generate high temperatures after prolonged operation. To extend the service life of the bearings, the heat of the bearing body 1 itself will be transferred to the interior of the heat-conducting plate 18. The power supply component 26 provides energy for the operation of the micro fan 24. The micro fan 24 generates wind power, which flows into the interior of the ventilation slot 21 through the air inlet pipe 19. The connecting pipe 20 allows the wind power to flow inside multiple ventilation slots 21. The ventilation slots 21 are in contact with the outer wall of the heat-conducting plate 18. When the wind power flows inside the ventilation slots 21, it can dissipate the heat absorbed by the heat-conducting plate 18. The hot air enters the interior of the exhaust head 28 through the exhaust pipe 22, and the wind power is transmitted to the outside through the exhaust head 28, thereby improving the efficiency of ventilation. The improved heat dissipation efficiency of the bearing bushes allows for rapid heat dissipation, extending the service life of the bearing bushes used in hydroelectric generator sets. When the bearing bushes experience significant friction with the internal shaft after prolonged use, lubricating oil is added to the oil supply tank 31 via the oil inlet pipe 30. The lubricating oil flows into the storage tank 32 and is absorbed by the oil-absorbing cotton 33. To add lubricating oil to the bearing bush body 1, the threaded screw 35 is rotated. The bottom end of the threaded screw 35 is movably connected to the drive frame 37. The threaded sleeve 36 moves the threaded screw 35, pushing the drive frame 37 to move vertically along the outer wall of the rod body 38. This movement of the drive frame 37 moves the pressure plate 39. When the pressure plate 39 moves, it squeezes the oil-absorbing cotton 33 inside the liquid storage tank 32, causing the lubricating oil absorbed by the cotton 33 to be squeezed out. The lubricating oil will flow into the first oil tank 2 through the drain pipe 34. When the shaft rotates inside the bearing body 1, the lubricating oil can be quickly applied to the inside of the bearing body 1, achieving the purpose of rapid lubrication. After long-term use of the bearing of the hydro-generator unit, when the internal friction is too high, the internal lubricating oil can be quickly applied to prevent damage to the hydro-generator unit caused by excessive friction, and at the same time, it can extend the service life of the bearing body 1. When it is necessary to seal the connection between the bearing and the shaft of the hydro-generator unit, an external air pump is used to transmit air pressure to the inside of the rubber air bag 42 through the air supply pipe 43.The rubber airbag 42 expands, causing the plate 44 to move. This movement, in turn, moves the lubricating block 45. Once the lubricating block 45 reaches the outer wall of the hydroelectric generator shaft, the external air pump stops operating, and the air supply pipe 43 is sealed. The plate 44 also blocks the connection between the hydroelectric generator and the bearing, effectively preventing external impurities from entering the bearing and affecting its normal operation. This achieves the goal of preventing large external impurities from entering the bearing through gaps.

First, when installing and using the bearing bush of the hydropower unit for the hydropower station, after installing the bearing bush inside the support, rotate the bolt (7) and the threaded ring (6) to move the bolt (7) to a position. One end of the bolt (7) is movably connected to the first connecting piece (8). When the bolt (7) moves, it pushes the drive plate (9) to move to a position. When the drive plate (9) moves to a position, it drives the first connecting frame (12) to move to a position. When the first connecting frame (12) moves, it pushes the second connecting frame (14) to move to a position through the connecting plate (13). When the second connecting frame (14) moves, it pushes the limit block (15) to move out of the limit assembly (5). After one end of the limit block (15) contacts the inner wall of the hydropower unit where the bearing bush is installed, it improves the stability of the bearing bush installation and achieves the purpose of improving the stability of the bearing bush installation. It effectively prevents the bearing bush from shaking and affecting the normal operation of the hydropower unit. S2. After a long period of operation, the bearings of the hydropower unit in the hydropower station will generate high temperatures. In order to extend the service life of the bearings, the heat of the bearing body (1) itself will be transferred to the interior of the heat-conducting plate (18). The power supply component (26) provides energy for the operation of the micro fan (24). The micro fan (24) generates wind power. The wind power flows into the interior of the ventilation slot (21) through the air inlet pipe (19). The connecting pipe (20) makes the wind power flow inside the multiple ventilation slots (21). The ventilation slot (21) is in contact with the outer wall of the heat-conducting plate (18). When the wind power flows inside the ventilation slot (21), it dissipates the heat absorbed by the heat-conducting plate (18). The hot air enters the interior of the exhaust head (28) through the exhaust pipe (22). The wind power is transmitted to the outside through the exhaust head (28), thereby improving the heat dissipation efficiency of the bearings and achieving the purpose of quickly dissipating heat from the bearings, thus extending the service life of the bearings used in the hydropower unit. S3. When the bearing bush of the hydroelectric generator set has been used for a long time and there is a large friction with the internal shaft, the lubricating oil to be added is added to the oil supply tank (31) through the oil inlet pipe (30). When the lubricating oil flows inside the oil supply tank (31), it will flow into the storage tank (32) for storage. The oil-absorbing cotton (33) absorbs the lubricating oil. When it is necessary to add lubricating oil to the inside of the bearing bush body (1), rotate the threaded screw (35). The bottom end of the threaded screw (35) is movably connected to the drive frame (37). When the threaded sleeve (36) moves the threaded screw (35) to a position, it will push the drive frame (37) to move vertically to the outer wall of the rod body (38). When moving, the pressure plate (39) moves to a different position. When the pressure plate (39) moves, it squeezes the oil-absorbing cotton (33) inside the liquid storage tank (32), causing the lubricating oil absorbed by the oil-absorbing cotton (33) to be squeezed out. The lubricating oil will flow into the interior of the No. 1 oil tank (2) through the drain pipe (34). When the shaft rotates inside the bearing body (1), the lubricating oil is quickly applied to the interior of the bearing body (1) to achieve the purpose of quickly applying the lubricating oil.

S4. When it is necessary to seal the connection between the bearing and the shaft of the hydro-generator unit, an external air pump is used to transmit air pressure to the inside of the rubber air bag (42) through the air supply pipe (43), causing the volume of the rubber air bag (42) to expand. When the volume of the rubber air bag (42) expands, it drives the plate (44) to move. When the plate (44) moves, it drives the lubricating block (45) to move. After the lubricating block (45) moves to the outer wall of the hydro-generator unit shaft, the external air pump stops working and the air supply pipe (43) is sealed. The plate (44) blocks the connection between the hydro-generator unit and the bearing, effectively preventing external impurities from entering the inside of the bearing and affecting the normal use of the bearing and the hydro-generator unit.
