[0002] A generator is a mechanical device that converts mechanical energy into electrical energy. It is typically driven by a water turbine, steam turbine, diesel engine, or other power machinery. The energy generated by water flow, airflow, fuel combustion, or nuclear fission is first converted into mechanical energy, which is then transferred to the generator, which ultimately outputs electrical energy.

[0029] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0030] This application discloses a generator vibration damping base, which is used to install a generator on top of it, and to provide an effective and comprehensive vibration damping effect during the operation of the generator.

[0031] Reference Figure 1 and Figure 2The shock-absorbing base includes a mounting base 1, a shock-absorbing base 2, a base plate 3, multiple first shock-absorbing devices 4, and multiple second shock-absorbing devices 5.

[0032] The base plate 3 is fixedly installed on the foundation or other supporting structure, and multiple first damping devices 4 are installed on the top of the base plate 3; the damping seat 2 is installed above the base plate 3, and it is connected to the base plate 3 through multiple first damping devices 4, and it can vibrate and displace relative to the base plate 3 in the vertical direction due to the vibration of the generator 9 during operation; multiple second damping devices 5 are installed on the damping seat 2, and the mounting seat 1 is connected to the damping seat 2 through multiple second damping devices 5, and it can vibrate and displace relative to the damping seat 2 in the horizontal direction due to the vibration of the generator 9 during operation; after the generator 9 is installed on the top of the mounting seat 1, the vibration generated during its operation will be damped by multiple first damping devices 4 and multiple second damping devices 5 respectively.

[0033] Reference Figure 3 and Figure 4 Both the base plate 3 and the shock absorber 2 are square plate structures. The base plate 3 and the shock absorber 2 have the same cross-sectional dimensions, and the base plate 3 and the shock absorber 2 are aligned in the vertical direction.

[0034] Reference Figure 2 and Figure 4 The center of the shock absorber 2 has space for the mounting base 1 to be installed and to move horizontally, and the shock absorber 2 has a structure that restricts the mounting base 1 to move only horizontally; the mounting base 1 is a circular plate structure, which is installed in a vertical position with its axis vertical, and the generator 9 is installed in the center of the top of the mounting base 1.

[0035] Reference Figure 2 and Figure 5 The first shock-absorbing device 4 includes a fixed member 41, a movable member 42, and several first springs 43. In this embodiment, the shock-absorbing base preferably includes four first shock-absorbing devices 4, and the installation positions of the four first shock-absorbing devices 4 are respectively close to the four sides of the base plate 3.

[0036] The fixed component 41 is fixedly installed on the top of the base plate 3 and located above the base plate 3. The top of the movable component 42 is fixedly connected to the shock absorber 2, and the bottom is movably connected to the fixed component 41 in the vertical direction. The first spring 43 is installed between the fixed component 41 and the movable component 42. It is installed vertically in the length direction, and its two ends are fixedly connected to the fixed component 41 and the movable component 42 respectively. It has the tendency to drive the fixed component 41 and the movable component 42 to maintain a certain relative position. At this time, when the generator 9 operates and generates vertical vibration, the vibration will be transmitted to the shock absorber 2 through the mounting base 1, thereby driving the movable component 42 to move vertically relative to the fixed component 41. The first spring 43 absorbs the vibration energy through its own elastic deformation, thereby achieving the vertical shock absorption effect. In this embodiment, it is preferred that the fixed component 41 and the movable component 42 are in a sleeve-type sliding fit, and the first spring 43 is installed inside the sleeve-type structure. Since the sleeve-type structure is a common prior art, it will not be described in detail here, and it is only briefly shown in the accompanying drawings.

[0037] Reference Figure 4 and Figure 5 The second damping device 5 includes two rotating parts 51 and several second springs 52, and the multiple damping devices are distributed on the circumference of the positioning seat along the horizontal direction. In this embodiment, the damping base preferably includes four second damping devices 5, and the installation positions of the four second damping devices 5 are respectively close to the four sides of the damping seat 2.

[0038] One end of a rotating component 51 is rotatably connected to the damping seat 2, and one end of another rotating component 51 is rotatably connected to the side of the mounting base 1. The rotation axes of both rotating components 51 are vertical. The rotation connection positions of multiple rotating components 51 with the damping seat 2 are arranged in a circular array with the vertical center line of the damping seat 2 as the axis, and the rotation connection positions of multiple rotating components 51 with the mounting base 1 are arranged in a circular array with the axis of the mounting base 1 as the axis. The other ends of the two rotating components 51 are movably connected to each other, and their direction of movement is consistent with their length directions. A second spring 52 is installed between the two rotating components 51, and its two ends in the length direction are fixedly connected to the two rotating components 51 respectively. It has the tendency to drive the two rotating components 51 to maintain a certain relative position. At this time, when the generator 9 operates and generates horizontal vibration, the vibration will be transmitted to the mounting base 1, causing the two rotating components 51 to rotate and move relative to each other. The second spring 52 absorbs the vibration energy through its own elastic deformation, thereby achieving the horizontal damping effect. In this embodiment, it is preferable that the two rotating parts 51 are also in a sleeve-type sliding fit, and the second spring 52 is installed inside the sleeve-type structure; and preferably, when the mounting seat 1 is centered relative to the shock absorber 2, the multiple second springs 52 maintain their original length, so that when the mounting seat 1 deviates from the centered position due to vibration, the multiple second springs 52 can apply a restoring force to the mounting seat 1 stably and in a timely manner.

[0039] Reference Figure 2 and Figure 3 Furthermore, in order to further improve the vibration damping effect of the vibration damping base during the operation of the generator 9 and to make the vibration damping more comprehensive, the vibration damping base preferably also includes an auxiliary device 6 that can provide vibration damping effect in both the horizontal and vertical directions.

[0040] The auxiliary device 6 is installed between the mounting base 1 and the base plate 3. Its installation position is centered relative to the base plate 3, and it includes two ball joints 61 and several auxiliary springs 62.

[0041] One end of a ball joint 61 is hinged to the bottom ball joint of the base plate 3, and its hinge position is centered on the base plate 3; one end of another ball joint 61 is hinged to the bottom ball joint of the mounting base 1, and its hinge position is centered on the mounting base 1; the other ends of the two ball joints 61 are movably connected to each other, and their movement direction is consistent with their length direction; an auxiliary spring 62 is installed between the two ball joints 61, and its two ends in the length direction are fixedly connected to the two ball joints 61 respectively, and it has the tendency to drive the two ball joints 61 to maintain a certain relative position state; at this time, when the generator 9 operates and generates vibration, the vibration will drive the mounting base 1 to move horizontally relative to the damping seat 2 and drive the damping seat 2 to move vertically relative to the base plate 3, thereby driving the two ball joints 61 to rotate and move relative to each other. The auxiliary spring 62 absorbs the vibration energy through its own elastic deformation, thereby achieving the vibration reduction effect in all directions. In this embodiment, it is preferred that the two ball joints 61 are also in a sleeve-type sliding fit, and the auxiliary spring 62 is installed inside the sleeve-type structure; and preferably, when the mounting seat 1 is centered relative to the shock absorber seat 2, the auxiliary spring 62 maintains its original length so that when the generator 9 is working and generating vibration, the auxiliary spring 62 can stably and promptly play a shock absorption role.

[0042] Reference Figure 5 and Figure 6 Furthermore, in order to further improve the damping effect of the first damping device 4 and facilitate the staff to adjust the damping effect of the first damping device 4 according to the needs, the first damping device 4 preferably also includes a force transmission component 44 for transmitting the force, and the damping base also includes an adjustment device 7 for adjusting the damping effect of the first damping device 4.

[0043] The adjustment device 7 includes a movable plate 71, an adjustment component 72 for adjusting the movable plate 71 to move vertically, and a plurality of adjustment springs 73 for adjusting the damping effect of the first damping device 4.

[0044] The force transmission component 44 is installed above the base plate 3 and located on one side of the corresponding fixing member 41. Multiple adjusting springs 73 correspond one-to-one with multiple first damping devices 4, therefore, multiple adjusting springs 73 correspond one-to-one with multiple force transmission components 44. In this embodiment, preferably, the force transmission component 44 is installed between the corresponding adjusting spring 73 and the corresponding moving member 42, for transmitting force between the corresponding adjusting spring 73 and the corresponding moving member 42.

[0045] The movable plate 71 has a square frame-like plate structure and is installed vertically between the base plate 3 and the shock absorber 2 with its center line in a vertical position. In this embodiment, preferably, the top of the base is vertically installed with a plurality of guide members 31 that are inserted and cooperate with the movable plate 71, which are used to guide the movable plate 71 to move vertically under the control of the adjusting component 72.

[0046] The adjustment assembly 72 is installed at the bottom of the shock absorber 2. It includes an adjustment rope 721 with one end fixedly connected to the movable plate 71, a winding member 722 for winding the other end of the adjustment rope 721, and a drive member 723 for controlling the winding member 722 to wind and release the adjustment rope 721.

[0047] The winding component 722 is rotatably connected to the shock absorber 2, and its rotation axis is horizontal. The driving component 723 is fixedly installed on the shock absorber 2 and is used to drive the winding component 722 to rotate relative to the shock absorber 2. The adjusting rope 721 is installed between the winding component 722 and the movable plate 71, and the height position of the movable plate 71 is adjusted by controlling the length of the adjusting rope 721 between the winding component 722 and the movable plate 71. In this embodiment, the driving component 723 is preferably a servo motor; since servo motors are common existing technology, they will not be described in detail here, and are only briefly shown in the accompanying drawings.

[0048] The adjusting spring 73 is fixedly installed vertically below the movable plate 71, and multiple adjusting springs 73 are arranged in a circular array on the movable plate 71 with the axis of the movable plate 71 as the axis. In this embodiment, it is preferable that the adjusting springs 73 remain in a stretched state during the process of adjusting the damping effect of the first damping device 4 by the adjusting device 7, so that the adjusting rope 721 located between the winding member 722 and the movable plate 71 can remain in a vertical and taut state.

[0049] The force transmission component 44 includes a buffer structure 441 and a pulley structure 442. The buffer structure 441 is close to the moving part 42, and the pulley structure 442 is close to the adjusting spring 73.

[0050] The buffer structure 441 includes a connecting rod, a lever, a slider, and a slide rail. One end of the connecting rod is hinged to the movable member 42, and the other end of the connecting rod is close to the pulley structure 442. The slide rail is fixedly installed on the base plate 3. The slider slides horizontally with the slide rail. The lever is vertically installed above the slider, and its top is hinged to the middle of the connecting rod. During the movement of the movable member 42 relative to the fixed member 41, it drives the connecting rod to rotate and simultaneously drives the slider to slide, dispersing the force and achieving a buffering effect. In this embodiment, since the buffer structure 441 is a common prior art, it will not be described in detail here, and the accompanying drawings only provide a brief representation.

[0051] The pulley structure 442 includes a pulley and a traction rope. The pulley is rotatably mounted between the end of the connecting rod away from the movable part 42 and the adjusting spring 73, with its rotation axis horizontal and perpendicular to the sliding direction of the slider. One end of the traction rope is fixedly connected to the bottom of the adjusting spring 73, and the other end is fixedly connected to the end of the connecting rod away from the movable part 42, and it is wound around the pulley. At this time, during the rotation of the connecting rod, it can drive the traction rope to apply a force to the adjusting spring 73, and the adjusting spring 73 has the effect of driving the buffer structure 441 to reset so that the first buffer device maintains a certain position. In this embodiment, it is preferable that during the operation of the force transmission component 44, the part of the traction rope connected to the adjusting spring 73 can maintain a vertical position. Since the above-mentioned pulley structure 442 is a common prior art, it will not be described in detail here, and it is only briefly shown in the accompanying drawings.

[0052] At this time, the staff can drive the winding component 722 to rotate through the drive component 723 according to the vibration of the generator 9 during operation. The winding component 722 winds up and unwinds the adjusting rope 721, thereby driving the movable plate 71 to move up or down. When the movable plate 71 moves up and down, it changes the tension of the adjusting spring 73, and then changes the force acting on the movable component 42 in the first shock absorber 4 through the force transmission component 44, thereby adjusting the shock absorption effect of the first shock absorber 4 on vertical vibration.

[0053] Furthermore, in order to enable the horizontal and vertical vibration trends generated by the generator 9 during operation to suppress each other, thereby comprehensively improving the vibration damping effect of the damping base on the generator 9, the damping base preferably also includes multiple linkage devices 8 for linking the first damping device 4 and the second damping device 5, and the multiple linkage devices 8 correspond one-to-one with the multiple second damping devices 5.

[0054] The linkage device 8 includes a rotating plate 81 and a drive wheel 82.

[0055] The rotating plate 81 has an overall annular plate structure. It is installed between the shock absorber 2 and the movable plate 71 with its axis vertically aligned, and its axis coincides with the vertical center line of the shock absorber 2. Multiple rotating plates 81 are spaced apart along their axial direction, and the end faces of adjacent rotating plates 81 are in contact with each other. The rotating plate 81 has a through hole 811 along its own axial direction for the adjustment rope 721 to pass through. The opening of the through hole 811 has an outward flaring structure to facilitate the adjustment rope 721 to pass through the through hole 811 and to facilitate the bending and deformation of the adjustment rope 721 at this point. Both sides of the rotating plate 81 along the axial direction have a relief groove 812 for the bent and deformed adjustment rope 721 to be inserted into. The relief groove 812 is annular and its axis coincides with the axis of the rotating plate 81. The relief groove 812 is connected to the through hole 811.

[0056] The drive wheel 82 is mounted on the inner side of the corresponding rotating plate 81 and is fixedly connected to the rotating component 51, which is rotatably mounted on the shock absorber 2. Its axis coincides with the rotation axis of the rotating component 51, and the rotating component 51 can drive the corresponding drive wheel 82 to rotate relative to the shock absorber 2 during its rotation. In this embodiment, preferably, the outer side of the drive wheel 82 has a toothed ring structure, the inner side of the rotating plate 81 has a toothed ring structure, and the drive wheel 82 meshes with the corresponding rotating plate 81.

[0057] At this time, when the mounting base 1 is displaced horizontally relative to the shock absorber 2 due to the vibration of the generator 9, it will drive multiple rotating parts 51 mounted on the shock absorber 2 to rotate relative to the shock absorber 2, thereby driving the corresponding rotating plate 81 to rotate through the drive wheel 82. During the rotation of the rotating plate 81, a horizontal force will be applied to the adjusting rope 721, causing the adjusting rope 721 to bend and deform. After being stressed, the adjusting rope 721 will drive the movable plate 71 to move upward, thereby increasing the tension of the adjusting spring 73, and thus improving the shock absorption effect of the multiple first shock absorbers 4. In this embodiment, the bottom of the shock absorber 2 preferably has a cylindrical protective cover 21, and the linkage device 8 is installed inside the protective cover 21, so that the protective cover 21 can provide physical protection for the linkage device 8 and prevent external debris from entering and interfering with the normal operation of the linkage device 8.

[0058] The implementation principle of a generator vibration damping base according to an embodiment of this application is as follows: During the operation of generator 9, vibrations are generated, which are mainly absorbed by multiple first vibration damping devices 4 and multiple second vibration damping devices 5. Among them, multiple first vibration damping devices 4 absorb vertical vibration energy to achieve vertical vibration damping, and multiple second vibration damping devices 5 absorb horizontal vibration energy to achieve horizontal vibration damping. According to the vibration reduction requirements, the staff can adjust the vibration reduction effect of multiple first vibration reduction devices 4 through the adjustment device 7; Meanwhile, during the operation of generator 9, both auxiliary device 6 and linkage device 8 can use the vertical vibration trend to suppress the horizontal vibration trend or use the horizontal vibration trend to suppress the vertical vibration trend, thereby effectively reducing vibration in generator 9.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
