Description

Technical Field

[0001] This application relates to the technical field of generator sets, and in particular to a generator set. Background Technology

[0002] Generator sets, as essential power supply equipment, play a crucial role in industrial production, commercial buildings, infrastructure, and emergency power applications. They convert mechanical energy into electrical energy by driving a generator through an internal combustion engine, thus providing stable and continuous power support for various electrical loads. With societal development, electricity demand continues to grow, and the complexity of energy systems is increasing. This makes the reliability, durability, and operational stability of generator sets increasingly important, especially in applications with high requirements for vibration and noise control. Vibration damping design directly impacts the long-term operational efficiency of the equipment and the quality of the surrounding environment.

[0003] Generator sets are mounted on the ground via support modules. To suppress the transmission of vibrations generated during generator operation, passive vibration damping solutions are commonly used as support modules in the industry. Common types include rubber damping pads, spring dampers, and hydraulic dampers. Among these, spring dampers are more widely used in medium and large-sized generator sets due to their advantages such as high load-bearing capacity, large deformation range, and good durability. These dampers generally consist of steel helical springs, upper and lower panels, and a protective structure. They primarily rely on the elastic deformation of the springs to absorb and isolate vibration energy, thereby reducing the vibration force transmitted to the foundation.

[0004] However, spring-type vibration dampers have certain drawbacks. Their damping performance tends to degrade after long-term continuous operation. This is because the spring material gradually undergoes fatigue relaxation under alternating stress, leading to changes in stiffness and a shift in resonant frequency, ultimately reducing the damping effect. This necessitates shutdown for maintenance, adjustment, or replacement of the spring components, which is not only cumbersome and costly but also causes power generation interruptions, making it extremely inconvenient in applications requiring high power continuity. Summary of the Invention

[0005] To facilitate the maintenance of generator sets, this application provides a generator set.

[0006] This application provides a generator set, which adopts the following technical solution: A generator set includes a generator set and a rigid support frame that carries the generator set; A support module is disposed at the bottom of the rigid support frame, and there are multiple support modules that are evenly spaced apart. The support module includes a top plate, a bottom plate, a first side plate, and a second side plate; The top plate is connected to the bottom of the rigid support frame, and the first side plate is symmetrically arranged at the bottom of the top plate. The first side plate is provided with a sliding groove. The second side plate slides up and down in the groove, the first side plate and the second side plate correspond one to one, the bottom plate is set at the bottom of the second side plate, and a shock-absorbing space is formed between the top plate and the bottom plate; Two spring modules are symmetrically arranged on the base plate, with one spring module located in the shock absorption space. At this time, there is a gap between the top of the second side plate and the top wall of the slide groove. A control component is disposed in the support module. When the second side plate slides to abut against the top wall of the slide groove, the control component controls the spring module in the shock absorption space to slide out, and controls another spring module to slide into the shock absorption space.

[0007] By adopting the above technical solution, the rigid support frame can support the generator set, and multiple evenly spaced support modules can stably support the rigid support frame. The top plate, first side plate, second side plate, and bottom plate of the support module form a vibration damping space, and the second side plate can slide in the groove. Two symmetrically arranged spring modules, one located in the vibration damping space, absorb and isolate vibration energy by utilizing the elastic deformation of the spring, reducing the impact of vibration on the generator set. When the top of the second side wall abuts against the top wall of the groove, it indicates that the vibration damping performance of the spring module may decrease. The control component can control the spring module in the vibration damping space to slide out and allow another unused spring module to slide in, without the need for shutdown maintenance, adjustment, or replacement of spring elements, reducing power generation interruptions, improving the continuity of power generation and the ease of use of the equipment, while ensuring the stability of the vibration damping effect.

[0008] Optionally, the spring module includes an upper mounting plate, a shock-absorbing spring, a lower mounting plate, and a telescopic column; The lower mounting plate is slidably connected to the base plate, the telescopic column is disposed on the top of the lower mounting plate, and the upper mounting plate is disposed on the top of the telescopic column; The shock-absorbing spring is sleeved on the outer periphery of the telescopic column, and the two ends of the shock-absorbing spring abut against the opposite sides of the upper mounting plate and the lower mounting plate, respectively. A linkage bar is provided between the opposing sides of the lower mounting plate.

[0009] By adopting the above technical solution, the upper mounting plate, damping spring, lower mounting plate, and telescopic column form a spring module. The lower mounting plate is slidably connected to the base plate, facilitating the movement of the spring module. The telescopic column is set on top of the lower mounting plate, and the upper mounting plate is set on top of the telescopic column to ensure the stability of the structural connection. The damping spring is sleeved on the outer periphery of the telescopic column, with its two ends abutting against the upper mounting plate and the lower mounting plate respectively. It can absorb and isolate vibration energy by utilizing the elastic deformation of the spring, reducing the vibration force transmitted to the foundation. A linkage bar is set between the opposing sides of the lower mounting plate to enable the two spring modules to move synchronously.

[0010] Optionally, the telescopic column includes an inner column and an outer column, the outer column is disposed on the lower mounting plate, the inner column is disposed on the upper mounting plate, and the inner column slides up and down on the outer column.

[0011] By adopting the above technical solution, the telescopic column adopts an inner column and an outer column structure. The inner column can slide up and down inside the outer column, which can guide and limit the extension and retraction of the shock-absorbing spring, ensuring that the shock-absorbing spring remains stable during compression and rebound, reducing the possibility of the shock-absorbing spring tilting or deviating, improving the stability and shock absorption effect of the spring module, and thus improving the overall performance of the generator set.

[0012] Optionally, the inner column is provided with a locking post, the bottom of the locking post is provided with a locking block, the lower mounting plate is provided with a locking groove for the locking block to be engaged, and the bottom of the locking block is inclined to form a driving surface; The base plate has a sliding insertion post, and the base plate is provided with a driving spring that drives the insertion post to protrude into the shock absorption space. The lower mounting plate has a through hole that connects to the locking slot. When the plug-in post passes through the through hole and is inserted into the locking slot, the plug-in post slides on the driving surface, pushing the locking block away from the locking slot.

[0013] By adopting the above technical solution, the spring module can be flexibly locked and unlocked, facilitating the switching of the spring module inside and outside the vibration damping space. This ensures that new vibration damping springs can be replaced in a timely manner after the performance of the original vibration damping springs deteriorates, maintaining the vibration damping performance of the generator set spring module, reducing the inconvenience and cost caused by downtime maintenance, and ensuring the continuity of power generation.

[0014] Optionally, the control assembly includes a control spring, a control column, and a connecting column; The control spring is disposed on the base plate and abuts against the lower mounting plate away from the shock absorption space. The upper mounting plate has an arc-shaped guide surface facing the top plate. The control column slides up and down on the base plate and corresponds one-to-one with the lower mounting plate. The bottom of the lower mounting plate is provided with a control slot for the control column to be inserted. The connecting post is disposed on the first side plate and slides up and down on the second side plate, and the connecting post is provided with a connecting strip that connects to the control post; When there is a gap between the second side plate and the top wall of the chute, the control column is inserted into the control groove; When the second side plate abuts against the top wall of the chute, the control column disengages from the control chute; The damping spring includes a first spring and a second spring. When the first spring is located in the damping space, the control spring is in a compressed state. When the second spring is located in the damping space, the control spring is in a relaxed state.

[0015] By adopting the above technical solution, when the performance of the damping spring deteriorates and the second side plate abuts against the top wall of the chute, the control column can be automatically disengaged from the control groove, allowing the control spring to drive the spring module to switch, so that the undamped damping spring can enter the damping space, reducing the frequency of downtime maintenance due to the decline in damping performance, reducing power generation interruptions, and ensuring power supply continuity.

[0016] Optionally, the top plate has a movable groove for the upper mounting plate to slide into.

[0017] By adopting the above technical solution, the sliding of the upper mounting plate is made more stable, ensuring the precise position of the spring module within the shock absorption space, thereby improving the overall reliability and shock absorption effect of the spring module.

[0018] Optionally, a movable groove is provided on the base plate, the lower mounting plate is slidably connected in the movable groove, and the control spring is installed in the mounting groove; The side wall of the lower mounting plate is provided with a limiting block, and the wall of the movable groove is provided with a limiting groove for the limiting block to slide.

[0019] By adopting the above technical solution, the lower mounting plate slides in the moving groove, which facilitates the adjustment of the spring module position. The spring can be stably installed in the mounting groove and function. The limiting block slides in the limiting groove to limit and guide the sliding of the lower mounting plate, ensuring the stability and accuracy of the spring module movement process and improving the overall performance and reliability of the generator set spring module.

[0020] Optionally, the inner column is threadedly connected to the upper mounting plate.

[0021] By adopting the above technical solution, the inner column is threadedly connected to the upper mounting plate, which facilitates the installation and disassembly of the inner column and the upper mounting plate, makes it easier to maintain and replace the spring module, and improves the maintainability of the generator set spring module.

[0022] In summary, this application includes at least one of the following beneficial effects: 1. By using multiple support modules to adapt to spring modules, the elastic deformation of the spring modules can absorb and isolate vibration energy, effectively reducing the vibration force transmitted to the foundation and meeting the requirements of generator sets for vibration and noise control. 2. A control component is set up so that when the shock absorption performance of a single spring module deteriorates due to long-term use, it can automatically switch to another spring module without stopping the machine for maintenance, adjustment or replacement of spring components, thus saving maintenance costs.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a generator set.

[0027] See Figure 1 and Figure 2 This application mainly adopts a shock absorption scheme with automatic switching of spring module 3, which achieves continuous and stable shock absorption without stopping the machine, reducing maintenance costs and power generation interruption. The following is a further detailed description of this application. Example

[0028] See Figure 1 and Figure 2 The generator set provided in this application includes a generator set, a rigid support frame 1 supporting the generator set, support modules 2, spring modules 3, and control components. The support modules 2 are located at the bottom of the rigid support frame 1, and there are multiple modules evenly spaced, providing stable support for the rigid support frame 1 and the generator set, ensuring the overall stability of the generator set. Two spring modules 3 are symmetrically arranged on the base plate 22 of the support module 2, absorbing and isolating vibration energy through the elastic deformation of the springs. The control components are located on the support module 2 and can control the sliding in and out of the spring modules 3 according to the state of the support module 2. This allows for automatic switching of the spring modules 3 when the vibration damping effect of one spring module 3 decreases to a certain extent, greatly facilitating generator set maintenance and ensuring continuous and stable vibration damping effect.

[0029] See Figure 2 and Figure 3 Specifically, the support module 2 includes a top plate 21, a bottom plate 22, a first side plate 23, and a second side plate 24. The top plate 21 is connected to the bottom of the rigid support frame 1 and is used to bear the weight of the generator set transmitted by the rigid support frame 1. The first side plate 23 is symmetrically fixed to the bottom of the top plate 21, and the first side plate 23 has a sliding groove 231. The second side plate 24 can slide up and down in the sliding groove 231, and the first side plate 23 and the second side plate 24 correspond one-to-one. The bottom plate 22 is fixedly connected to the bottom of the second side plate 24, and a shock-absorbing space 25 is formed between the top plate 21 and the bottom plate 22. One spring module 3 is installed in the shock-absorbing space 25. At this time, there is a gap between the top of the second side plate 24 and the top wall of the sliding groove 231. The top plate 21 can be a flat steel plate, and the shape of the top plate 21 can be designed according to the shape of the bottom of the rigid support frame 1, generally rectangular. The first side plate 23 can be fixed to the bottom of the top plate 21 by welding to ensure the firmness of the connection. The second side plate 24 can be a plate adapted to the first side plate 23, and the material of the second side plate 24 can also be steel plate. The bottom plate 22 can be a relatively thick steel plate, used to support the entire support module 2 and spring module 3. When the generator set vibrates during operation, the rigid support frame 1 transmits the vibration to the top plate 21, and then the top plate 21 transmits the vibration to the spring module 3, so that the spring module 3 buffers the vibration transmitted by the top plate 21. As the damping effect of the spring module 3 continues to decrease, the distance between the top plate 21 and the bottom plate 22 gradually decreases.

[0030] See Figure 4 and Figure 5 Specifically, the spring module 3 includes an upper mounting plate 31, a shock-absorbing spring 32, a lower mounting plate 33, and a telescopic column 34. A movable groove 221 is provided on the base plate 22, and the lower mounting plate 33 is slidably connected to the movable groove 221.

[0031] See Figure 2 A limiting block 333 is fixedly connected to the side wall of the lower mounting plate 33, and a limiting groove 222 is provided in the groove wall of the moving groove 221 to allow the limiting block 333 to slide. The moving groove 221 can be a dovetail groove or a T-shaped groove, etc., to guide the sliding of the lower mounting plate 33. The function of the limiting block 333 and the limiting groove 222 is to limit the sliding range of the lower mounting plate 33 and reduce the possibility of the lower mounting plate 33 sliding out of the moving groove 221. The control spring 41 is installed in the mounting groove 211 to ensure its installation stability.

[0032] See Figure 4 and Figure 5 The lower mounting plate 33 is slidably connected to the base plate 22, and the telescopic column 34 is disposed on the top of the lower mounting plate 33. The upper mounting plate 31 is fixed to the top of the telescopic column 34. The shock-absorbing spring 32 is sleeved on the outer periphery of the telescopic column 34, and the two ends of the shock-absorbing spring 32 abut against the opposing sides of the upper mounting plate 31 and the lower mounting plate 33, respectively. A linkage bar 35 is provided between the opposing sides of the lower mounting plates 33, so that the two opposing lower mounting plates 33 can be linked. The upper mounting plate 31 and the lower mounting plate 33 can be circular or square plates, and the material can be high-strength aluminum alloy or steel. The shock-absorbing spring 32 can be a helical spring, and the material of the shock-absorbing spring 32 is generally spring steel, which has good elasticity and fatigue resistance. The function of the telescopic column 34 is to guide the extension and retraction direction of the shock-absorbing spring 32 and ensure the stability of the shock-absorbing spring 32 during the extension and retraction process. The linkage bar 35 can be a metal rod, and the two ends of the linkage bar 35 are fixedly connected to the two lower mounting plates 33, so that the two spring modules 3 can move synchronously. When the lower mounting plate 33 slides on the base plate 22, the telescopic column 34 moves accordingly, and the shock-absorbing spring 32 expands and contracts according to the change in distance between the upper mounting plate 31 and the lower mounting plate 33, thereby absorbing and isolating vibration energy.

[0033] Specifically, the telescopic column 34 includes an inner column 341 and an outer column 342. The outer column 342 is fixedly connected to the lower mounting plate 33, and the inner column 341 is fixedly connected to the upper mounting plate 31. The inner column 341 slides up and down on the outer column 342. The inner column 341 and the outer column 342 can be cylindrical rods made of stainless steel. A clearance fit can be used between the inner column 341 and the outer column 342 to ensure that the inner column 341 can slide smoothly within the outer column 342. This structure makes the telescopic column 34 more stable during telescopic movement and better guides the extension and retraction of the shock-absorbing spring 32.

[0034] Specifically, a locking pin 343 is fixedly connected to one end of the bottom of the inner column 341, and a locking block 344 is fixedly connected to the bottom of the locking pin 343. A locking groove 331 is provided on the lower mounting plate 33 for the locking block 344 to be engaged, and a driving surface 345 is formed at the bottom of the locking block 344 at an angle. The locking pin 343 has a certain elastic deformation capability. When the locking block 344 is aligned with the locking groove 331, the locking pin 343 recovers its elastic deformation, driving the locking block 344 to be engaged in the locking groove 331. At this time, the shock-absorbing spring 32 is in a compressed state.

[0035] The base plate 22 has a sliding insertion post 5, and a drive spring 51 is installed on the base plate 22 to drive the insertion post 5 to protrude into the damping space 25. The lower mounting plate 33 has a through hole 346 that connects to the locking groove 331. When the insertion post 5 is aligned with the through hole 346, the drive spring 51 drives the insertion post 5 to slide upward through the through hole 346 and insert into the locking groove 331. At this time, the insertion post 5 slides on the drive surface 345, pushing the locking block 344 away from the locking groove 331, thereby releasing the locking state between the inner post 341 and the lower mounting plate 33, allowing the damping spring 32 to enter the elastic release state. The locking post 343 and the locking block 344 can be an integrally formed structure, and the material can be carbon steel. The shape of the locking groove 331 is adapted to the locking block 344 to ensure that the locking block 344 is accurately engaged.

[0036] See Figure 2 and Figure 3 Specifically, the control components include a control spring 41, a control column 42, and a connecting column 4. The control spring 41 is installed in the moving groove 221 and abuts against the lower mounting plate 33 away from the shock absorption space 25. The upper mounting plate 31 has an arc-shaped guide surface 311 facing the top plate 21, which facilitates the upper mounting plate 31 sliding into the bottom of the top plate 21.

[0037] The control column 42 slides up and down on the base plate 22 and corresponds one-to-one with the lower mounting plate 33. The bottom of the lower mounting plate 33 has a control groove 332 for the control column 42 to be inserted. The connecting column 4 is fixedly connected to the top wall of the slide groove 231 and slides up and down on the second side plate 24. The connecting column 4 is fixedly connected to the connecting strip 43. The end of the connecting strip 43 away from the connecting column 4 is connected to the fixed control column 42, so that when the first side plate 23 slides down, the control column 42 can drive the connecting column 4 to slide down through the connecting strip 43. When there is a gap between the second side plate 24 and the top wall of the slide groove 231, the control column 42 is inserted into the control groove 332; when the second side plate 24 abuts against the top wall of the slide groove 231, the control column 42 is disengaged from the control groove 332.

[0038] See Figure 3 and Figure 5The damping spring 32 includes a first spring 321 and a second spring 322. In the initial state, the first spring 321 is located within the damping space 25, at which time the control spring 41 (the control spring 41 is in...) Figure 4 The control spring 41 is in a compressed state when the second spring 322 is in the damping space 25. The control spring 41 can be a compression spring, used to provide power for switching the spring module 3. The control column 42 can be a cylindrical rod, made of copper alloy. The function of the connecting column 4 and the connecting strip 43 is to transmit the movement of the second side plate 24 to the control column 42, realizing the insertion and disengagement of the control column 42. When there is a gap between the second side plate 24 and the top wall of the slide groove 231, the control column 42 is inserted into the control groove 332, restricting the sliding of the spring module 3; when the second side plate 24 abuts against the top wall of the slide groove 231, the control column 42 disengages from the control groove 332, the control spring 41 releases energy, and pushes the spring module 3 into or out of the damping space 25.

[0039] See Figure 4 Specifically, the top plate 21 has a mounting groove 211 for the upper mounting plate 31 to slide into. The shape of the mounting groove 211 is adapted to the upper mounting plate 31, ensuring the smooth sliding of the upper mounting plate 31 within the mounting groove 211. When the spring module 3 slides into the damping space 25, the upper mounting plate 31 can accurately engage with the mounting groove 211, ensuring the connection stability between the spring module 3 and the top plate 21.

[0040] See Figure 4 and Figure 5 Specifically, the inner column 341 is threadedly connected to the upper mounting plate 31. This connection method makes the connection between the inner column 341 and the upper mounting plate 31 more secure, and also facilitates the disassembly and replacement of the shock-absorbing spring 32. During installation, the inner column 341 can be rotated to tighten and fix the inner column 341 to the upper mounting plate 31; when it is necessary to replace the inner column 341 or the upper mounting plate 31, they can be removed by rotating them in the opposite direction.

[0041] The implementation principle of a generator set in this application embodiment is as follows: The generator set is supported by a rigid support frame 1, with support modules 2 providing stable support. When vibrations occur during generator operation, spring modules 3 absorb and isolate vibration energy using the elastic deformation of damping springs 32. When the damping performance of one spring module 3 deteriorates due to long-term use, causing the second side plate 24 to abut against the top wall of the slide groove 231, the supporting capacity of the spring module 3 on the rigid support frame 1 decreases. At this point, the top plate 21 drives the first side plate 23 to slide downwards until the top of the second side plate 24 abuts against the top wall of the slide groove 231. The control component then controls the spring module 3 in the damping space 25 to slide out, while simultaneously controlling the other spring module 3 to slide into the damping space 25, achieving automatic switching of the spring modules 3 and facilitating generator maintenance. This allows for continuous and stable damping without shutting down the generator, reducing maintenance costs and power generation interruptions, and improving the reliability and operational stability of the generator set, representing a significant improvement over traditional generator sets.

[0042] 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.
