Description

Technical Field

[0001] This utility model relates to the field of diesel generator vibration reduction, and in particular to a high-speed diesel generator vibration reduction and stabilization device. Background Technology

[0002] Generators are important equipment in modern industry and power systems. Their function is to generate electrical energy for use. However, generators often generate vibrations during operation, which not only reduce the performance of the generator, but may also have a negative impact on the surrounding environment and other equipment.

[0003] Existing generator bases often lack shock absorption or have only one type of shock absorption method, resulting in unsatisfactory shock absorption. When faced with vibrations from a diesel generator, the base is prone to slippage, which seriously affects the stability and working efficiency of the generator. If the diesel generator itself malfunctions and causes significant vibrations during operation, it is difficult for staff to detect in time, which can easily lead to safety accidents.

[0009] The stroke section includes a stroke slider and a stroke spring. The stroke slider is slidably mounted on the transverse slide rod.

The auxiliary lifting component includes a proximity switch, a control unit, and a hydraulic lifting component.

[0014] Compared with the prior art, the high-speed diesel generator vibration damping and stabilizing device according to the present invention, after the first and second damping components are subjected to vibration, the compression block moves downward, and at the same time drives the stroke slider to move away from the compression fixed seat to both sides, thereby decomposing the vertically downward force into the lateral forces. In the above process, the compression block will compress the compression spring. When the compression spring is compressed downward, it will generate an opposite upward elastic force, thereby reducing part of the downward pressure. The movement of the stroke slider away from the compression fixed seat will stretch the stroke spring, and the stroke spring will generate an opposite contraction force while being stretched, thereby also reducing the lateral stretching force. This achieves the decomposition and cancellation of pressure, improves the vibration damping effect of the diesel generator during operation, increases the service life of the damping spring and the stroke spring, and avoids safety accidents.

[0032] The base fixing plate 3000 is disposed on top of the first shock absorber 2100 and the second shock absorber 2200;

[0033] The auxiliary lifting component 4000 includes a proximity switch unit, a control unit, and a hydraulic lifting component 4300.

[0034] The high-speed diesel generator is mounted on the base fixing plate 3000. When the high-speed diesel generator is operating at high speed, the vibration damping principle of the high-speed diesel generator vibration damping and stabilization device of this invention is as follows: the high-speed diesel generator vibrates and presses the base fixing plate 3000 downward. The base fixing plate 3000 moves downward, driving the compression block 2110 on the first damping member 2100 and the second damping member 2200 to move downward synchronously. The compression block 2110 will slide on the compression rod 2130. When the compression block 2110 moves downward, the other end of the compression rod 2130 will extend into the compression groove 2111. At the same time, the compression block 2110 compresses the compression spring 2140. During the descent of the compression block 2110, the first hinge plate 2150 and the second hinge plate 2160 will drive the stroke slider 2171 to move away from the compression fixing seat 2120, thereby dispersing the downward pressure. When block 2171 moves away from compression base 2120, it stretches the stroke slider 2171 and the stroke springs 2172 on both sides of compression base 2120. At this time, the stroke springs 2172 still have a relative contraction force during the stretching process, which slows down the movement stroke and speed of the stroke slider 2171, counteracts the downward pressure of compression block 2110, and thus improves the overall lifespan of stroke spring 2172 and pressure relief spring. When the base fixing part is no longer subjected to downward pressure, the stroke spring 2172 returns to its initial state from the stretched state, causing the stroke slider 2171 to move towards compression base 2120, and assists in lifting compression block 2110 through the first hinge plate 2150 and the second hinge plate 2160. During this process, the compression spring 2140 returns to its initial state from the compressed state, thereby causing the first damper 2100 and the second damper 2200 to return to their initial states, waiting for the next vibration to press down.

[0035] Furthermore, such as Figure 1 and Figure 2 As shown, the high-speed diesel generator vibration damping and stabilizing device also includes an auxiliary lifting component 4000. The auxiliary lifting component 4000 includes a proximity switch part, a control part, and a hydraulic lifting component 4300. The proximity switch part includes a first proximity block 4110, a second proximity block 4120, and a third proximity block 4130. The first proximity block 4110 is located at one end of the transverse slide bar 2300, the second proximity block 4120 is located at the center of the transverse slide bar 2300, and the third proximity block 4130 is located at the other end of the transverse slide bar 2300. The first damping component 2100 is located between the first proximity block 4110 and the second proximity block 4120. Between the approach blocks 4120, the second shock absorber 2200 is located between the second approach block 4120 and the third approach block 4130. The first approach block 4110, the second approach block 4120 and the third approach block 4130 are all equipped with proximity sensors, which are connected to the control unit. A hydraulic lifting member 4300 is provided between two adjacent first-stage shock absorbers 2000, and the hydraulic lifting member 4300 is located on one side of the first shock absorber 2100 and the second shock absorber 2200. The hydraulic lifting member 4300 is connected to the controller, and a lifting plate 4310 is provided at the output end of the hydraulic lifting member 4300. During repeated use, the lifespan of the stroke spring 2172 is significantly shortened after repeated compressions. The stroke spring 2172 is prone to breakage, which prevents the stroke slider 2171 from returning to its original position and absorbing downward force, causing the base fixing plate 3000 to shift. This seriously affects the stability and working efficiency of the diesel generator. Therefore, by setting the auxiliary lifting component 4000, the shift of the base fixing plate 3000 caused by the breakage of the stroke spring 2172 is avoided, thereby improving the stability of the diesel generator.

[0036] The working principle of the auxiliary lifting component 4000 is as follows: Figure 3 and Figure 4 As shown, when the stroke spring 2172 of the first shock absorber 2100 breaks, the stroke slider 2171 slides close to and contacts the first proximity block 4110 and the second proximity block 4120 respectively. At this time, the proximity sensors on the first proximity block 4110 and the second proximity block 4120 generate corresponding contact signals and transmit the contact signals to the control unit. The program set in the control unit analyzes and processes the contact signals. After processing, the signal controls the hydraulic lifting component 4300 to start, so that the lifting plate 4310 of the hydraulic lifting component 4300 quickly contacts the base fixing plate 3000 and lifts the base fixing plate 3000 to a specific height according to the program setting to prevent the diesel generator from deviating.

[0037] Preferably, the control unit uses a controller, which is existing technology and will not be described in detail here.

[0038] Furthermore, such as Figure 1 and Figure 2 As shown, the high-speed diesel generator vibration damping and stabilization device also includes multiple secondary damping components 5000. These secondary damping components 5000 are disposed on the bottom surface of the mounting cavity 1100, close to the inner wall of the mounting cavity 1100, and positioned between adjacent primary damping components 2000. When the compression spring 2140 and stroke spring 2172 in the primary damping component 2100 and the secondary damping component 2200 malfunction, causing the base fixing plate 3000 to shift, the base fixing plate 3000 will contact the secondary damping component 5000 before the hydraulic lifting component 4300 of the auxiliary lifting component 4000 has lifted it, preventing excessive shifting of the base fixing plate 3000 and damage to the diesel generator.

[0039] Furthermore, such as Figure 1 and Figure 2 As shown, the secondary damper 5000 employs a damper, and one end of the secondary damper 5000 is equipped with an abutment plate 5100, which cooperates with the base fixing plate 3000. When the base fixing plate 3000 shifts, and the hydraulic jacking component 4300 fails to lift it, the shifted base fixing plate 3000 contacts the abutment plate 5100 of the secondary damper 5000. The damper used in the secondary damper 5000 significantly reduces the continued descent of the base fixing plate 3000, thus providing sufficient time for the hydraulic jacking component 4300 to lift the base fixing plate 3000, stabilizing its height and preventing damage to the diesel generator.

[0040] Preferably, the high-speed diesel generator vibration damping and stabilization device also includes an alarm. The controller is connected to the alarm. When the controller controls the hydraulic lifting component 4300 to work, the controller will simultaneously control the alarm to sound, thereby prompting on-site personnel or personnel in the central monitoring room to deal with the corresponding faults in a timely manner, such as replacing the travel spring 2172 or the compression spring 2140.
