Description

Technical Field

[0001] This invention relates to the field of generator technology, specifically to a high-efficiency generator based in a power plant. Background Technology

[0002] Generators are a new generation of power generation equipment with the core objectives of improving the efficiency of the entire energy conversion process, reducing energy loss and carbon emissions, and adapting to stable operation under wide loads in multiple scenarios. Their scope covers all application scenarios, including thermal power, hydropower, gas power, wind power, distributed emergency power generation, and new energy supporting power generation. They are the core basic equipment for global energy low-carbon transformation, the construction of new power systems, and industrial energy conservation and carbon reduction. Their development and popularization are important signs of energy revolution and manufacturing upgrading. The core working principle of generators follows Faraday's law of electromagnetic induction and the law of electromagnetic force. Through power machinery such as water turbines, steam turbines, and diesel engines, the generator rotor is driven to rotate, so that the excitation magnetic field generated by the rotor forms a relative motion with the stator armature winding. The winding conductors continuously cut the magnetic field lines, generating an induced electromotive force in the closed circuit, which in turn forms a continuous induced current, and finally completes the stable conversion of mechanical energy into electrical energy.

[0003] Existing generators use a double-ring oil seal structure to seal the motor shaft. During long-term operation, continuous vibration of the shaft system causes progressive wear of the sealing tiles in the oil seal structure. The shaft journal surface forms circumferential annular grooves due to long-term friction. The combined effect of these two factors causes the single-sided gap between the dynamic and static sides of the seal to exceed the design allowable value. A stable and continuous dynamic pressure sealing oil film cannot be formed within the dynamic and static gap, directly causing hydrogen gas inside the generator to leak outward along the dynamic and static gap, posing a serious risk of combustion and explosion. If a sealing ring is directly added for secondary protection, the sealing ring needs to be in direct contact with the high-speed rotating shaft. During unit operation, continuous friction and wear will occur, and its sealing protection performance will rapidly decline with operating time, making it impossible to achieve long-term stable sealing protection.

[0004] To address the aforementioned issues, innovative design based on existing methods is urgently needed. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency generator based on a power plant, in order to solve the technical problem in the background art where, during the operation of a high-efficiency generator, vibration causes progressive wear of the Babbitt alloy layer on the working surface of the sealing tile, and long-term friction forms circumferential annular grooves on the surface of the shaft journal. The combined effect of these two factors results in the single-sided gap between the dynamic and static seals far exceeding the design allowable value, and a stable and continuous dynamic pressure sealing oil film cannot be formed within the dynamic and static gaps, directly causing hydrogen gas inside the generator to leak outward along the dynamic and static gaps, posing a serious safety hazard of combustion and explosion. This invention provides a solution that is significantly different from the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency generator based on a power plant, comprising a generator body, a main rotating shaft installed inside the generator body, a protective frame connected to the outside of the generator body, a rotating frame connected to the inside of the protective frame, and the rotating frame being rotatably connected to the generator body housing, a telescopic rod installed inside the rotating frame, a transmission plate connected to the output end of the telescopic rod, a first partition plate connected to the inside of the protective frame, a transmission rod rotatably connected to the first partition plate, a placement ring threadedly connected to the transmission rod, the placement ring being slidably connected to the rotating frame, a sealing ring sleeved on the inclined surface of the placement ring, a compression ring slidably connected to the inside of the rotating frame, and the compression ring being threadedly connected to the transmission rod, a second partition plate also connected to the inside of the rotating frame, and the second partition plate being rotatably connected to the transmission rod, and a limit ring sleeved on the main rotating shaft, and the limit ring being slidably connected to the placement ring;

[0007] A pushing component is disposed inside the rotating frame.

[0008] Preferably, the pushing assembly includes an adjusting rod disposed inside the rotating frame, and the adjusting rod is rotatably connected to the first partition plate. The adjusting rod is threadedly connected to a threaded sleeve, one end of which is connected to a piston frame. Both the inner and outer walls of the piston frame are provided with expansion sealing gaskets. An expansion sealing gasket is connected to the inner side of the piston frame, and a liquid storage frame is connected to the expansion sealing gasket via a hose. A piston plate is slidably connected to the liquid storage frame. The adjusting rod is slidably connected to a threaded rod, and the threaded rod is rotatably connected to the piston frame and threadedly connected to the piston plate rod body.

[0009] Preferably, the transmission plate has a transmission hole and a circular protrusion is provided inside the transmission hole, the transmission rod has a first rotating groove, and the circular protrusion of the transmission plate is located in the first rotating groove of the transmission rod.

[0010] Preferably, the limiting ring is slidably connected to the limiting block, and a spring is connected to the bottom of the limiting block, with the other end of the spring connected to the limiting ring.

[0011] Preferably, the outer ring of the extrusion ring is provided with a sealing rubber pad, and the sealing rubber pad is in contact with the inner wall of the rotating frame.

[0012] Preferably, the limiting ring is provided with four sets of limiting protrusions, and the limiting protrusions are slidably connected to the placement ring.

[0013] Preferably, the threaded sleeve is slidably connected to the second partition, the threaded sleeve is slidably connected to the placement ring, and the threaded sleeve is slidably connected to the compression ring.

[0014] Preferably, the adjusting rod has a second rotating groove, and the circular protrusion of the transmission plate is located in the second rotating groove.

[0015] Preferably, the inner side of the adjusting rod is provided with a cross protrusion, and the cross protrusion is slidably connected to the threaded rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, when a leak occurs, the generator main body alarm will activate, which will start the telescopic rod. The telescopic rod will drive the transmission plate to move. The movement of the transmission plate will cause the placement ring and the compression ring to move. The movement of the placement ring will cause the sealing ring to fit against the outside of the main shaft, and the movement of the compression ring will press the sealing ring to make it fit tightly against the outside of the main shaft. The compression of the sealing ring and the compression ring will close the rotating frame, thereby preventing the leakage of oil and hydrogen. In the absence of a leak, there will be a gap between the sealing ring and the main shaft, thereby preventing the sealing ring from wearing during the rotation of the main shaft.

[0018] 2. In this invention, the transmission plate also drives the piston frame to move during the movement of the transmission plate. The movement of the piston frame pushes the oil inside the rotating frame towards the generator body. During the movement of the piston frame, the expansion sealing gasket will gradually unfold, and the oil pressure will gradually increase by pushing the oil body, thereby reducing the occurrence of the gradual aggravation of leakage. In addition, the piston frame and the rotating frame will form a temporary oil chamber, allowing the generator body to continue to work for a short time, providing a buffer time, and making it convenient for the staff to shut down the associated equipment to maintain the generator body.

[0029] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structure, features, and effects of the present invention.

[0030] Please see Figures 1 to 9 This invention provides a technical solution: a high-efficiency generator based on a power plant, comprising a generator body 1, a main rotating shaft 2 installed inside the generator body 1, a protective frame 3 connected to the outside of the generator body 1, a rotating frame 4 connected to the inside of the protective frame 3, and the rotating frame 4 rotatably connected to the housing of the generator body 1, a telescopic rod 5 installed inside the rotating frame 4, a transmission plate 6 connected to the output end of the telescopic rod 5, a first partition 7 connected to the inside of the protective frame 3, a transmission rod 8 rotatably connected to the first partition 7, a placement ring 9 threadedly connected to the transmission rod 8, and the placement ring 9 slidably connected to the rotating frame 4, a sealing ring 11 sleeved on the inclined surface of the placement ring 9, a compression ring 10 slidably connected to the inside of the rotating frame 4, and the compression ring 10 threadedly connected to the transmission rod 8, and a second partition 10 also connected to the inside of the rotating frame 4. Plate 13, and the second partition plate 13 is rotatably connected to the transmission rod 8. The main shaft 2 is sleeved with a limit ring 12, and the limit ring 12 is slidably connected to the placement ring 9. When leakage occurs, the alarm of the generator body 1 will be activated, and the telescopic rod 5 will be activated. The telescopic rod 5 will drive the transmission plate 6 to move. The movement of the transmission plate 6 will cause the placement ring 9 and the compression ring 10 to move. The movement of the placement ring 9 will cause the sealing ring 11 to fit against the outside of the main shaft 2. The movement of the compression ring 10 will press the sealing ring 11 to make it fit tightly against the outside of the main shaft 2. The compressed sealing ring 11 and the compression ring 10 will close the rotating frame 4, thereby preventing the leakage of oil and hydrogen. When there is no leakage, there will be a gap between the sealing ring 11 and the main shaft 2, thereby preventing the sealing ring 11 from wearing during the rotation of the main shaft 2.

[0031] Push component 14 is located inside the rotating frame 4.

[0032] In one embodiment of the present invention, the pushing assembly 14 includes an adjusting rod 141 disposed inside the rotating frame 4, and the adjusting rod 141 is rotatably connected to the first partition plate 7. The adjusting rod 141 is threadedly connected to a threaded sleeve 142, one end of which is connected to a piston frame 143. Expansion sealing gaskets 144 are provided on both the inner and outer walls of the piston frame 143. The expansion sealing gasket 144 is connected to the inner side of the piston frame 143, and a liquid storage frame 145 is connected to the expansion sealing gasket 144 via a hose. A piston plate 146 is slidably connected to the liquid storage frame 145. A threaded rod 147 is slidably connected to the adjusting rod 141, and the threaded rod 147 is connected to the piston frame 143. 43 is rotated and connected, and the threaded rod 147 is threadedly connected to the piston plate 146. During the movement of the transmission plate 6, the piston frame 143 will also move. The movement of the piston frame 143 pushes the oil inside the rotating frame 4 towards the generator body 1. During the movement of the piston frame 143, the expansion sealing gasket 144 will gradually unfold. By pushing the oil body, the pressure of the oil body will gradually increase, thereby reducing the gradual aggravation of leakage. The piston frame 143 and the rotating frame 4 will form a temporary oil chamber, allowing the generator body 1 to continue to work for a short time, providing a buffer time, and making it convenient for the staff to shut down the associated equipment to maintain the generator body 1.

[0033] As one embodiment of the present invention, the transmission plate 6 has a transmission hole and a circular protrusion is provided inside the transmission hole. The transmission rod 8 has a first rotating groove and the circular protrusion of the transmission plate 6 is located in the first rotating groove of the transmission rod 8. By moving the transmission plate 6, the transmission rod 8 can be driven to rotate, which in turn can drive the placement ring 9 and the compression ring 10 to move.

[0034] In one embodiment of the present invention, the limiting ring 12 is slidably connected to the limiting block, and the bottom of the limiting block is connected to a spring, and the other end of the spring is connected to the limiting ring 12. By setting the slidable limiting block, the moving sealing ring 11 can be limited to avoid the sealing ring 11 from moving off course. Furthermore, by setting the spring, the limiting block can be quickly pushed back to its initial position.

[0035] As one embodiment of the present invention, a sealing rubber gasket is provided on the outer ring of the extrusion ring 10, and the sealing rubber gasket is in contact with the inner wall of the rotating frame 4. By providing the rubber sealing gasket, the contact between the extrusion ring 10 and the rotating frame 4 can be sealed, reducing the possibility of oil leakage.

[0036] As one embodiment of the present invention, the limiting ring 12 is provided with four sets of limiting protrusions, and the limiting protrusions are slidably connected to the placement ring 9. By providing four sets of limiting protrusions, the sealing ring 11 can be better limited, thereby improving the stability of the sealing ring 11 during movement.

[0037] In one embodiment of the present invention, the threaded sleeve 142 is slidably connected to the second partition 13, the threaded sleeve 142 is slidably connected to the placement ring 9, and the threaded sleeve 142 is slidably connected to the compression ring 10. The second partition 13 can limit the threaded sleeve 142 and improve the stability of the threaded sleeve 142 during horizontal movement.

[0038] In one embodiment of the present invention, the adjusting rod 141 is provided with a second rotating groove, and the circular protrusion of the transmission plate 6 is located in the second rotating groove. By moving the transmission plate 6, the adjusting rod 141 can be driven to rotate, which in turn can drive the piston frame 143 to move.

[0039] In one embodiment of the present invention, a cross protrusion is provided on the inner side of the adjusting rod 141, and the cross protrusion is slidably connected to the threaded rod 147. By providing the cross protrusion, the threaded rod 147 can be limited, so that the adjusting rod 141 can drive the threaded rod 147 to rotate synchronously during the rotation process.

[0040] Working principle: First, when hydrogen and oil leak on the oil seal side, the oil and hydrogen will enter the inner side of the rotating frame 4, and the alarm installed on the generator body 1 will be activated. The standby telescopic rod 5 will be started by wireless remote control. Since the output end of the telescopic rod 5 is connected to the transmission plate 6, the operation of the telescopic rod 5 will drive the transmission plate 6 to move. Since the circular protrusion of the transmission plate 6 is located in the first rotating groove of the transmission rod 8, the horizontal movement of the transmission plate 6 will drive the transmission rod 8 to rotate.

[0041] Secondly, since the transmission rod 8 is threadedly connected to the placement ring 9 and the placement ring 9 is slidably connected to the rotating frame 4, the rotation of the transmission rod 8 will drive the placement ring 9 to move horizontally. Since the sealing ring 11 is in contact with the limiting ring 12, the horizontal movement of the placement ring 9 will gradually separate it from the sealing ring 11. Since the placement ring 9 is threadedly connected to the extrusion ring 10 and the extrusion ring 10 is slidably connected to the rotating frame 4, the rotation of the transmission rod 8 will also drive the extrusion ring 10 to move. The movement of the extrusion ring 10 pushes the sealing ring 11 to apply pressure. Under the influence of pressure, the sealing ring 11 is tightly attached to the outside of the main rotating shaft 2. The extrusion ring 10 and the sealing ring 11 seal the rotating frame 4, preventing the leakage of oil and hydrogen from the inside of the rotating frame 4.

[0042] Finally, since the circular protrusion of the transmission plate 6 is located in the second rotating groove of the adjusting rod 141, the movement of the transmission plate 6 will also cause the adjusting rod 141 to rotate. Since the adjusting rod 141 is threadedly connected to the threaded sleeve 142, and the threaded sleeve 142 is fixedly connected to the piston frame 143, the rotation of the adjusting rod 141 will cause the threaded sleeve 142 to move horizontally. The horizontal movement of the threaded sleeve 142 will drive the piston frame 143 to move horizontally. Since the adjusting rod 141 is slidably connected to the threaded rod 147, and the threaded rod 147 is rotatably connected to the piston frame 143, the rotation of the adjusting rod 141 will drive the threaded rod 147 to rotate. Since the threaded rod 147 is threadedly connected to the piston plate 146, and the piston plate 146 is slidably connected to the liquid storage frame 145, the threaded rod 147... The movement of the piston plate 146 causes it to move inside the liquid storage box 145. Since the expansion sealing gasket 144 is connected to the liquid storage box 145 via a hose, the movement of the piston plate 146 will input the filling oil inside the liquid storage box 145 into the expansion sealing gasket 144, causing it to expand. The expansion sealing gasket 144 inside the piston frame 143 expands and fits against the main rotating shaft 2, while the expansion sealing gasket 144 outside the piston frame 143 expands and fits against the inner wall of the rotating frame 4. At this time, the movement of the piston frame 143 will push the leaking oil to move, so that the piston frame 143 and the rotating frame 4 form a small oil cavity, allowing the generator body 1 to still work for a short time, providing a buffer, and making it easier for the staff to gradually shut down the associated equipment. After maintenance, the staff can replace the worn sealing ring 11 and expansion sealing gasket 144 for subsequent protection.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
