Description

Technical Field

[0001] The invention relates to the technical field of generators, and in particular to a generator vibration reduction device. Background Art

[0002] A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine or other power machinery, converting the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy, and then the generator converts the mechanical energy into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology, and daily life. Existing generators are prone to vibration during operation. Long-term vibration can easily cause the generator parts to loosen and deform, affecting the normal operation of the generator.

[0003] Patent application number: 202211629807.2 proposes a generator vibration damping device, including a generator body, the bottom of the generator body is fixedly connected to a fixed base, the outer side of the fixed base is fixedly connected to a soft transverse slide, the bottom of the generator body is provided with a shock absorbing mechanism and an auxiliary buffer mechanism, the shock absorbing mechanism includes a shock absorbing shell, the inner wall of the shock absorbing shell is movably connected to the outer surface of the bottom end of the soft transverse slide. When the generator body generates a more violent vibration during use, an extrusion impact force will be generated on the internal structure of the shock absorbing shell through the fixed base, and the push plate will be driven by the support column to move downward along the inner wall of the limit sleeve plate, so that it cooperates with the fixed bottom plate, so that the support spring is compressed and elastically deformed, and the action time of the impact force on the generator body is extended through the action of the support spring, thereby forming a shock absorbing protection effect on the generator body as a whole.

[0004] After the device has been working for a long time, the internal spring assembly may produce irreversible deformation, causing the generator to be unable to remain level, affecting the normal operation of the generator, shortening the service life of the generator, and making it difficult to meet the use requirements of the power plant.

The elastic insertion plate cooperates with the slot of the buffer main plate, and its polyurethane material further absorbs and disperses vibration energy, thereby improving the stability and durability of the overall structure. The device can form a variety of shock-absorbing systems through the coordination of shock-absorbing feet, elastic insertion plates and buffer main plates, elastic pads and springs, thereby further improving the shock-absorbing effect of the device.

[0020] 3. The generator vibration damping device, when the generator works for a long time and a damping foot is damaged, the generator may be deflected. The horizontal state of the generator is monitored in real time through the horizontal sensor, and the data is transmitted to the processor. If it is detected that the generator deviates from the horizontal position, the processor will control the electric push rod (adjustment rod) to work, and adjust the height or posture of the generator through the push block until it returns to the horizontal state. If the adjustment fails or the vibration exceeds the preset range, the processor will trigger the alarm light to prompt the operator to check, so that the operator can repair the device conveniently.

[0029] A buffer cavity is provided inside the shock-absorbing box 1, and support rods 7 are fixedly installed at the edges of the buffer cavity. A connecting hole matching the support rod 7 is provided on the surface of the support plate 2, and the top ends of the support rods 7 extend to the top of the support plate 2 through the connecting hole. A thread is provided on the top outer surface of the support rod 7, and a nut 10 is assembled on the top end of the support rod 7 through a threaded screw connection. The bottom surface of the nut 10 abuts against the upper surface of the support plate 2, and a spring 15 is sleeved on the outer surface of the support rod 7. The bottom end of the spring 15 is fixedly connected to the inner wall of the buffer cavity, and the bottom end of the spring 15 is fixedly connected to a push plate 9, and the upper surface of the push plate 9 abuts against the support plate 2. A connecting plate 31 is fixedly installed on the bottom surface of the generator 3, and a mounting plate 32 is fixedly installed on the bottom end of the connecting plate 31, and the mounting plate 32 is arranged above the shock-absorbing foot 6;

[0030] When the generator 3 is running, it generates vibrations, which are first transmitted to the support plate 2 through the mounting plate 32 and the shock-absorbing foot 6. The vibration of the support plate 2 drives itself to move on the support rod 7. The spring 15 and the push plate 9 on the support rod 7 further absorb the vibration energy. The push plate 9 abuts against the support plate 2, converting the vibration into compression and recovery deformation of the spring, thereby dissipating the vibration energy.

[0031] See also Figure 6The shock-absorbing foot 6 includes a stainless steel base 61, a buffer sleeve 62 is fixedly installed on the upper surface of the stainless steel base 61, a support shell 63 is fixedly installed on the upper surface of the buffer sleeve 62, a threaded hole is opened at the center of the upper surface of the shock-absorbing foot 6, a bolt 33 is installed at the edge of the upper surface of the mounting plate 32, and the mounting plate 32 is fixedly connected to the shock-absorbing foot 6 through the bolt 33. When the generator 3 is running, vibrations are generated, and these vibrations are first transmitted to the support plate 2 through the mounting plate 32 and the shock-absorbing foot 6. The buffer sleeve 62 and the support shell 63 in the shock-absorbing foot 6 provide a preliminary shock-absorbing effect, reducing the vibration directly transmitted to the support plate 2;

[0032] Furthermore, a mounting groove 64 is opened at the edge of the stainless steel base 61, and a bolt 65 is arranged in the mounting groove 64. The shock-absorbing foot 6 is fixedly mounted on the support plate 2 by the bolt 65. By removing the bolt 33 and the bolt 65, the shock-absorbing foot 6 can be removed from the bottom of the generator 3, so that the shock-absorbing foot 6 can be maintained and replaced conveniently.

[0033] Among them, a plurality of elastic pads 14 are fixedly installed inside the shock absorbing box 1, and the top of the elastic pad 14 abuts against the support plate 2, and the elastic pad 14 provides additional shock absorbing support under the support plate 2; an elastic insertion plate 11 is fixedly installed at the center of the upper surface of the support plate 2, and a buffer main body plate 12 is fixedly installed on the inner wall of the buffer cavity. A slot 13 is opened on the upper surface of the buffer main body plate 12, and the slot 13 matches the elastic insertion plate 11. When the support plate 2 moves, it will drive the elastic insertion plate 11 to move and insert it into the slot 13 on the buffer main body plate 12 to open the buffer main body plate 12. The elastic insertion plate 11 cooperates with the slot 13 of the buffer main body plate 12, and its polyurethane material further absorbs and disperses vibration energy, thereby improving the stability and durability of the overall structure. The device can form a variety of shock absorbing systems through the cooperation of shock absorbing feet 6, elastic insertion plates and buffer main body plates 12, elastic pads 14, and springs 15, thereby further improving the shock absorbing effect of the device.

[0034] Furthermore, the thickness of the upper end of the elastic insertion plate 11 is greater than that of the lower end. When the elastic insertion plate 11 is inserted into the interior of the buffer main plate 12, the wider upper portion will drive the slot 13 on the buffer main plate 12 to expand and deform, further absorbing the vibration.

[0035] The elastic insert plate 11 , the buffer main body plate 12 and the elastic pad 14 are all made of polyurethane and have good damping properties.

[0036] Among them, the adjustment rod 8 includes an electric push rod fixedly installed on the upper surface of the support plate 2, a push block is fixedly installed on the top of the electric push rod, a level sensor 4 is fixedly installed on the side of the connecting plate 31, a processor 5 is fixedly installed on one side of the upper surface of the support plate 2, and an alarm light is fixedly installed on the upper surface of the processor 5. The processor 5 is electrically connected to the level sensor 4 and the adjustment rod 8 respectively. A vibration sensor is also provided on the processor 5 for detecting the vibration amplitude of the support plate 2.

[0037] When the generator 3 works for a long time and one of the shock absorbing feet 6 is damaged, the generator 3 may be deflected. The horizontal state of the generator 3 is monitored in real time by the horizontal sensor 4, and the data is transmitted to the processor 5. If it is detected that the generator deviates from the horizontal position, the processor 5 will control the electric push rod (adjustment rod 8) to work, and adjust the height or posture of the generator 3 by pushing the block until the horizontal state is restored. If the adjustment fails or the vibration exceeds the preset range, the processor 5 will trigger the alarm light to prompt the operator to check, so that the operator can repair the device conveniently.

[0038] Working principle: The generator vibration damping device generates vibration when the generator 3 is running. These vibrations are first transmitted to the support plate 2 through the mounting plate 32 and the damping foot 6. The buffer sleeve 62 and the support shell 63 in the damping foot 6 provide a preliminary damping effect to reduce the vibration directly transmitted to the support plate 2. The vibration of the support plate 2 will drive itself to move on the support rod 7. The spring 15 and the push plate 9 on the support rod 7 further absorb the vibration energy. The push plate 9 abuts against the support plate 2 and converts the vibration into compression and recovery deformation of the spring, thereby dissipating the vibration energy. At the same time, the elastic pad 14 provides additional damping support under the support plate 2.

[0039] When the support plate 2 moves, it will drive the elastic insertion plate 11 to move, insert into the slot 13 on the buffer main plate 12, and open the buffer main plate 12. The elastic insertion plate 11 cooperates with the slot 13 of the buffer main plate 12, and further absorbs and disperses the vibration energy through its polyurethane material, thereby improving the stability and durability of the overall structure. The device can form a variety of shock absorption systems through the cooperation of the shock absorbing foot 6, the elastic insertion plate and the buffer main plate 12, the elastic pad 14, and the spring 15, further improving the shock absorption effect of the device;

[0040] When the generator 3 works for a long time and one of the shock absorbing feet 6 is damaged, the generator 3 may be deflected. The horizontal state of the generator 3 is monitored in real time by the horizontal sensor 4, and the data is transmitted to the processor 5. If it is detected that the generator deviates from the horizontal position, the processor 5 will control the electric push rod (adjustment rod 8) to work, and adjust the height or posture of the generator 3 by pushing the block until the horizontal state is restored. If the adjustment fails or the vibration exceeds the preset range, the processor 5 will trigger the alarm light to prompt the operator to check, so that the operator can repair the device conveniently.
