Description
Technical Field
[0001] This invention belongs to the technical field of diesel generator sets, and more specifically, relates to diesel generator sets based on intelligent control. Background Technology
[0002] A diesel generator set consists of a diesel engine, a generator, a coupling, and a control device. The diesel engine drives the generator to produce electricity, which is then output to the outside. The diesel engine's vibration is relatively large, which can affect the generator's rotation and cause malfunctions. These malfunctions include generator instability, abnormal vibration and noise, changes in operating speed and output power, and abnormalities in the temperature, pressure, and flow rate of the medium.
[0003] However, existing rotors are prone to axial movement during long-term operation. If the movement is within a reasonable range, it usually does not significantly affect the unit. But when the movement intensifies, the rotor's axial position is usually fixed by components such as lock nuts, thrust washers, and positioning sleeves. If these positioning components loosen due to vibration, thermal expansion and contraction, or insufficient installation torque, the rotor's axial constraint will suddenly fail, causing the rotor movement to exceed the normal range. Therefore, the movement will cause fluctuations in generator output voltage and frequency, affecting power supply stability. If the movement causes the rotor to collide with the stator, it may generate a huge impact force instantly, causing deformation of the generator end cover and bending of the shaft, forcing the unit to shut down urgently. Existing alarm technologies often focus on monitoring macroscopic electrical parameters or environmental parameters such as voltage, current, and temperature. When these parameters exceed the set threshold, an alarm is triggered. However, this alarm method is often difficult to identify specific mechanical faults such as rotor axial movement in a timely and accurate manner. This is because rotor axial movement may not significantly affect macroscopic parameters in the early stages, and by the time abnormal parameters appear, the fault has often developed to a relatively serious level.
[0004] In view of this, the present invention is proposed. Summary of the Invention
[0005] To address the issue that existing alarm technologies often focus on monitoring macroscopic electrical or environmental parameters such as voltage, current, and temperature, triggering an alarm when these parameters exceed set thresholds; however, this alarm method often struggles to provide timely and accurate identification of specific mechanical faults like rotor axial movement. This is because rotor axial movement may not initially significantly affect macroscopic parameters, and by the time abnormalities appear, the fault has often progressed to a more serious stage. The basic concept of the technical solution adopted in this invention is:

[0007] In a preferred embodiment of the present invention, a cover plate is provided at the end of the circular mounting plate away from the diesel generator, and a plurality of fixing bolts arranged in a circular pattern are provided through the cover plate.
[0008] In a preferred embodiment of the present invention, the circular mounting plate is provided with four movable grooves arranged in a circular pattern. Each of the four movable grooves has a movable slider slidably disposed therein. The four movable sliders are symmetrical to each other in pairs. One end of each of the four movable sliders is provided with a first return spring. The other end of each of the four first return springs is disposed on the inner wall of the movable groove. The ends of the four movable sliders that are away from the movable grooves are disposed on the mounting block.
[0009] In a preferred embodiment of the present invention, each of the four rectangular rods has a rectangular slot through it, and each of the four rectangular slots has a plurality of grooves and convex surfaces on one side wall, and a rectangular moving rod is slidably disposed in the inner cavity of each of the four rectangular slots.
[0010] In a preferred embodiment of the present invention, each of the four rectangular moving rods is provided with an installation slot, and each of the four installation slots is provided with a placement slot, which extends through one side wall of the rectangular moving rod.
[0011] In a preferred embodiment of the present invention, guide grooves are provided on the opposite side walls of the four mounting slots, each guide groove is symmetrical to the other, and a guide slider is slidably provided in the inner cavity of each guide groove, each guide slider is symmetrical to the other, and a movable plate is provided at one end of each pair of guide sliders.
[0012] In a preferred embodiment of the present invention, each of the four movable plates is provided with a fitting block on one side wall away from the mounting slot. The four fitting blocks are movably inserted through the mounting slot and fit into the groove. Each of the four movable plates is provided with a second return spring at one end away from the fitting block, and the other ends of the four second return springs are respectively provided on the inner wall of the mounting slot.
[0013] In a preferred embodiment of the present invention, each of the four rectangular moving rods has a positioning plate at one end opposite to the other, and the four positioning plates are symmetrical to each other.
[0014] In a preferred embodiment of the present invention, each of the four mounting blocks has a concave plate on one side wall opposite to each other, and each concave plate is symmetrical to the other. Each concave plate has a guide rail on one side wall opposite to each other, and each guide rail is symmetrical to the other. Each guide rail is slidably connected to each other, and each sliding rod is symmetrical to the other.

[0015] In a preferred embodiment of the present invention, an annular fixing plate is provided on the front side of the circular mounting plate, and the annular fixing plate is used to limit the movement of the slider.
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] This invention, when the rotor moves axially, can first drive the mounting block to move via the positioning plate, and then drive the placement plate to move synchronously via the movement of the mounting block. When the mounting block cannot move, the maximum movement distance of the placement plate is limited to this area, thus preventing the rotor from moving further and reducing damage. At the same time, when the mounting block cannot move, the rotor's movement can also squeeze the positioning plate, causing the rectangular moving rod to touch the touch switch, which in turn controls the operation of the audible and visual alarm component to trigger an alarm and alert the operator to the damage. Therefore, it ensures that the rotor can be detected even when it moves axially.
[0018] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.
[0038] Example 1:
[0039] like Figures 1 to 12 As shown, the intelligent control-based diesel generator set includes a diesel generator set 1, a diesel generator 11 mounted on one side of the diesel generator set 1, an audible and visual alarm assembly 12 mounted above the diesel generator set 1, a rotor 114 mounted at the output end of the diesel generator 11, a snap-fit slot 115 at the end of the rotor 114 away from the diesel generator 11, a mounting ring 111 mounted on the front side wall of the diesel generator 11, a circular mounting plate 13 mounted inside the mounting ring 111, and a touch switch 1 mounted on one side wall of the mounting ring 111. 21; The inner cavity of the mounting ring 111 is also provided with four mounting blocks 2 arranged in a circular pattern. The side walls of the four mounting blocks 2 opposite to each other are provided with slots, and the inner cavity of the slots is provided with rectangular rods 21. The inner cavities of the four rectangular rods 21 are all provided with rectangular moving rods 22. The side walls of the four rectangular moving rods 22 opposite to each other are provided with positioning plates 227. The inner cavity of the mounting ring 111 is provided with four telescopic rods 32 arranged in a circular pattern. The end of each of the four telescopic rods 32 away from the mounting ring 111 is provided with a placement plate 321. When the rotor 114 moves axially, the positioning plate 227 can first drive the mounting block 2 to move, and the mounting block 2 can drive the placement plate 321 to move synchronously. When the mounting block 2 cannot move, the maximum moving distance of the placement plate 321 is within this area, thus preventing the rotor 114 from moving further and reducing damage. At the same time, when the mounting block 2 cannot move, the rotor 114 can also squeeze the positioning plate 227 when it moves, causing the rectangular moving rod 22 to touch the touch switch 121, so that the touch switch 121 controls the sound and light alarm component 12 to run, thereby triggering an alarm and alerting the staff that damage has occurred.
[0040] like Figures 1 to 3As shown, in a specific embodiment, a cover plate 112 is provided at the end of the circular mounting plate 13 away from the diesel generator 11, and a plurality of fixing bolts 113 arranged in a circular pattern are provided through the cover plate 112. In this configuration, the components on the front side of the circular mounting plate 13 are defined.
[0041] like Figures 4 to 9 and Figures 11 to 12 As shown, the circular mounting plate 13 further comprises four circumferentially distributed sliding grooves 131. Each of the four sliding grooves 131 has a sliding slider 132 slidably mounted within its inner cavity. The four sliding sliders 132 are symmetrically arranged in pairs. A first return spring 133 is attached to one end of each sliding slider 132, and the other end of each first return spring 133 is attached to the inner wall of the sliding groove 131. The ends of each sliding slider 132 away from the sliding groove 131 are mounted on the mounting block 2. This configuration determines the opening and installation positions of the sliding grooves 131 and the sliding sliders 132, ensuring that the mounting block 2 can move horizontally.
[0042] Example 2:
[0043] The difference between Embodiment 1 and this embodiment is that: Figures 4 to 9 and Figures 11 to 12 As shown, in the intelligent control-based diesel generator set, four rectangular rods 21 each have a rectangular slot 211 extending through them. Each of the four rectangular slots 211 has multiple grooves 212 and convex surfaces 213 on one side wall. A rectangular moving rod 22 is slidably mounted inside each of the four rectangular slots 211. In this design, the positions of the grooves 212 and convex surfaces 213 within the rectangular slots 211 are determined.
[0044] like Figures 7 to 9 and Figures 11 to 12 As shown, in a specific embodiment, each of the four rectangular moving rods 22 has a mounting slot 221, and each of the four mounting slots 221 has a placement slot, which penetrates one side wall of the rectangular moving rod 22. In this configuration, the mounting position of the rectangular moving rod 22 is determined.
[0045] like Figures 7 to 9 and Figures 11 to 12 As shown, furthermore, guide grooves 222 are provided on the opposite side walls of the inner cavities of the four mounting slots 221. Each guide groove 222 is symmetrical to the others. A guide slider 223 is slidably disposed in the inner cavity of each guide groove 222. Each guide slider 223 is symmetrical to the others. A movable plate 224 is provided at one end of each pair of opposite guide sliders 223. In this configuration, the movable plate 224 can be moved.
[0046] like Figures 7 to 9 and Figures 11 to 12As shown, furthermore, each of the four movable plates 224 has a locking block 226 on one side wall away from the mounting slot 221. The four locking blocks 226 movably pass through the mounting slot and engage with the groove 212. Each of the four movable plates 224 has a second return spring 225 at one end away from the locking block 226, and the other ends of the four second return springs 225 are respectively located on the inner wall of the mounting slot 221. In this configuration, it is ensured that when the locking block 226 moves from the groove 212 to the convex surface 213, the locking block 226 will be able to press the movable plate 224 to move with the assistance of the guide groove 222 and the guide slider 223, thereby pressing the second return spring 225 through the movable plate 224.
[0047] like Figures 1 to 3 As shown, furthermore, each of the four rectangular moving rods 22 has a positioning plate 227 at one end opposite to the other, and the four positioning plates 227 are symmetrical to each other. In this configuration, it is ensured that when the rotor 114 rotates, if it experiences axial movement, the rotor 114 will press the positioning plate 227 to move horizontally.
[0048] Example 3:
[0049] The difference between Embodiment 2 and this embodiment is that: Figures 4 to 9 and Figure 12 As shown, in the intelligent control-based diesel generator set, four mounting blocks 2 have concave plates 3 on each of their opposite side walls. Each pair of concave plates 3 is symmetrical. Each pair of concave plates 3 has guide rails 311 on its opposite side walls. Each pair of guide rails 311 is symmetrical. Each pair of guide rails 311 has sliding rods 31 slidably mounted between them. Each pair of sliding rods 31 is symmetrical. The end of each sliding rod 31 furthest from the mounting block 2 is located at the output end of a telescopic rod 32. Each of the four telescopic rods 32 has a placement plate 321 furthest from the inner cavity of the mounting ring 111. The four placement plates 321 are symmetrical. A ring-shaped fixing plate 4 is provided on the front side of the circular mounting plate 13, which limits the movement of the slider 132. In this configuration, when the mounting block 2 moves, it can also drive the concave plate 3 to move. When the concave plate 3 moves, it can drive the telescopic rod 32 to retract through the sliding rod 31, thereby driving the placement plate 321 to move. Therefore, when the mounting block 2 cannot move, the placement plate 321 cannot move. This ensures that when the audible and visual alarm component 12 alarms, the placement plate 321 can limit the rotor 114 to this area. Thus, to a certain extent, it can ensure that the rotor 114 will not continue to move axially and aggravate, thereby preventing further damage.
[0050] The implementation principle of the intelligent control-based diesel generator set of the present invention is as follows:
[0051] Firstly, when the operator uses the diesel generator 11, the diesel generator 11 drives the rotor 114 to rotate. When the rotor 114 rotates and axial movement occurs, the rotor 114 will press against the positioning plate 227 and move it horizontally. This is because the positioning plate 227 is connected to the rectangular moving rod 22, which is connected to the rectangular rod 21, which in turn is connected to the mounting block 2. The mounting block 2 is connected to the moving slider 132, thus ensuring that the mounting block 2 can move within the moving slider. With the assistance of 132 and the movable slide 131, the first return spring 133 is compressed (wherein, because the rectangular moving rod 22 is engaged with the groove 212 opened at the rectangular slot 211 on the rectangular rod 21 by the engaging block 226, and when the rectangular moving rod 22 is subjected to force, because the second return spring 225 is provided below the engaging block 226, and the elastic force of the second return spring 225 is greater than the elastic force of the first return spring 133, it is ensured that the engaging block 226 cannot move out of the groove 212 at this time).
[0052] When the mounting block 2 moves to a certain position, the movable slider 132 on the mounting block 2 will come into contact with the annular fixing plate 4. Therefore, the movable slider 132 will be limited by the annular fixing plate 4, which will prevent the movable slider 132 from moving.
[0053] At this time, when the rotor 114 moves axially downward, it can squeeze the positioning plate 227. Therefore, the rectangular moving rod 22 can be subjected to moving force. When the rectangular moving rod 22 is subjected to force, it can drive the wedge block 226 from the groove 212 opened in the inner cavity of the rectangular slot 211 to the convex surface 213 (because the moving slider 132 cannot move at this time). When the wedge block 226 moves from the groove 212 to the convex surface 213, the wedge block 226 can squeeze the moving plate 224 to move with the assistance of the guide groove 222 and the guide slider 223, thereby squeezing the second return spring 225 through the moving plate 224.
[0054] When the rotor 114 continues to move axially, it will be able to squeeze the positioning plate 227 and drive the rectangular moving rod 22 to move, thereby allowing the rectangular moving rod 22 to drive the mating block 226 to move from the convex surface 213 to the groove 212. At this time, the mating block 226 will be able to be reset under the elastic force of the second reset spring 225.
[0055] The above content is repeated until the end of the rectangular moving rod 22 away from the rotor 114 contacts the touch switch 121. At this time, the touch switch 121 will be able to drive the sound and light alarm component 12 to run, so that the sound and light alarm component 12 can sound an alarm, thereby reminding the staff that the rotor 114 is damaged.
[0056] Meanwhile, when the mounting block 2 moves, it can also drive the concave plate 3 to move. When the concave plate 3 moves, it can drive the telescopic rod 32 to retract through the sliding rod 31, thereby driving the placement plate 321 to move (where the sliding rod 31 and the concave plate 3 are slidably connected through the guide rail 311, thus ensuring that the sliding rod 31 can always be connected to the telescopic rod 32). Therefore, when the mounting block 2 cannot move, the placement plate 321 cannot move each time, thus ensuring that when the audible and visual alarm component 12 alarms, the placement plate 321 can limit the rotor 114 to this area. Therefore, to a certain extent, it can ensure that the rotor 114 will not continue to move axially and aggravate, thus preventing further damage.
