Description

Technical Field

[0001] This utility model relates to the field of generator bases, specifically a multi-stage shock-absorbing and buffer base for generators. Background Technology

[0002] A generator is a mechanical device that converts other forms of energy into electrical energy. It has a wide range of uses in industrial and agricultural production, national defense, science and technology, and daily life. As the scope of generator use gradually expands, people's requirements for generator bases are also gradually increasing. A generator base is generally a base structure for fixing the generator.

[0003] Chinese Patent Publication No. CN215267926U discloses a vibration-damping base for a generator, including a generator body, a mounting base plate at the bottom of the generator body, two connecting frames on the mounting base plate, a connecting rod fixedly connected to the bottom of the generator body, a buffer mechanism for damping vibrations of the generator body within the connecting frames, and a strip-shaped through groove on the mounting base plate containing a clamping mechanism for clamping and fixing the connecting frames. This invention, through the combination of the above structures, achieves damping and shock absorption of vibrations generated by the generator body during operation, ensuring the normal operation of the generator body. Furthermore, it allows for simple and quick disassembly and assembly of the connecting frames, i.e., disassembly and assembly of the generator body, improving operational efficiency.

[0004] The generator base shock absorption structure in the aforementioned patent simply uses a spring as a shock absorption component. However, when the spring is compressed and rebounds, it will vibrate and cannot function effectively as a shock absorption component. Summary of the Invention

[0005] The purpose of this utility model is to provide a multi-stage shock-absorbing and buffer base for generators, which has multi-stage shock absorption to effectively reduce the vibration generated during generator operation and to counteract the vibration generated when the spring rebounds, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage shock-absorbing and buffer base for a generator, comprising a bottom frame, a fixing block at the lower end of the bottom frame, a stepped rubber pad on the fixing block, and a fixing base, the fixing base being disposed on the upper end of the stepped rubber pad, a first connecting flange on the fixing base, a hydraulic damper at the upper end of the first connecting flange, a second connecting flange on one side of the first connecting flange, a limit tube on the second connecting flange, a connecting spring inside the limit tube, and a connecting plate at the upper end of the connecting spring.

[0007] Preferably, the connecting plate is provided with a top frame, and the top frame is bolted to the connecting plate.

[0008] Preferably, the top frame has a second bolt hole, which is integrally formed with the top frame.

[0009] Preferably, the top frame has a fixing groove, and the fixing groove is integrally formed with the top frame.

[0010] Preferably, the fixing block has a first bolt hole, which is integrally formed with the fixing block.

[0011] Preferably, the stepped rubber pad contains soft rubber columns.

[0012] Preferably, the fixed base has a through hole at the position corresponding to the first bolt hole.

[0013] Preferably, a limit block is provided on the fixed base.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model provides a connecting spring connected by a connecting plate at the lower end of the top frame as the first shock-absorbing component, which can effectively reduce the vibration generated by the generator that is working in the fixed groove. Then, the stepped rubber pad at the lower end serves as the second shock-absorbing component to further absorb and offset the vibration. Finally, the hydraulic damper at the lower end of the top frame can absorb the vibration generated by the connecting spring when it rebounds, so that the originally depressed top frame can rise and reset stably.

[0016] 2. The stepped rubber pad is composed of two parts. The outer layer is made of hard rubber in a stepped shape, which can ensure the overall strength of the rubber pad and extend its service life. The inner part is wrapped with soft rubber pillars to enhance the shock absorption function of the stepped rubber pad. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To address the problem that existing technologies using only springs as damping components in generator bases suffer from vibrations when compressed and rebounding, thus failing to effectively function as damping components, this embodiment provides the following technical solution:

[0024] A multi-stage vibration damping and buffer base for a generator includes a bottom frame 1, a fixing block 2 at the lower end of the bottom frame 1, a stepped rubber pad 4 on the fixing block 2, and a fixing base 5 on the upper end of the stepped rubber pad 4. A first connecting flange 8 is mounted on the fixing base 5, a hydraulic damper 9 is mounted on the upper end of the first connecting flange 8, a second connecting flange 10 is mounted on one side of the first connecting flange 8, a limit tube 11 is mounted on the second connecting flange 10, a connecting spring 12 is installed inside the limit tube 11, and a connecting plate 13 is mounted on the upper end of the connecting spring 12. The top frame 14 is provided on the top plate 3, and the top frame 14 is bolted to the connecting plate 13. The top frame 14 has a second bolt hole 15, which is integrally formed with the top frame 14. The top frame 14 has a fixing groove 16, which is integrally formed with the top frame 14. The fixing block 2 has a first bolt hole 3, which is integrally formed with the fixing block 2. The stepped rubber pad 4 has a soft rubber column 17. The fixing base 5 has a through hole 6 at the corresponding position of the first bolt hole 3. The fixing base 5 has a limit block 7.

[0025] In this embodiment, please refer to Figures 1-4The lower end of the top frame 14 is provided with a connecting spring 12 connected by a connecting plate 13 as the first shock absorber, which can effectively reduce the vibration generated by the generator that is working in the fixed groove 16. Then, the stepped rubber pad 4 at the lower end acts as the second shock absorber to further absorb the vibration. Then, the hydraulic damper 9 at the lower end of the top frame 14 can absorb the vibration generated by the connecting spring 12 when it rebounds, so that the originally depressed top frame 14 can rise and reset stably. The stepped rubber pad 4 is composed of two parts. The outer layer is made of hard rubber in a stepped shape, which can ensure the overall strength of the rubber pad and extend its service life. The inner part is wrapped with soft rubber pillars 17 to enhance the shock absorption function of the stepped rubber pad.

[0026] Working principle: The operator first uses fasteners such as bolts to pass through the through holes on the fixed base 5, and then through the first bolt hole 3 to install the bottom frame 1 on other devices or planes. Then, the generator is inserted into the fixed groove 16, and the fasteners are passed through the bolt holes opened on the generator housing until they are driven into the second bolt hole 15 to complete the connection between the generator and the top frame 14. The vibration generated by the generator operation will be absorbed and damped by the connecting spring 12 connected to the lower end through the connecting plate 13. The hydraulic damper 9 at the lower end of the top frame 14 can absorb the vibration generated by the connecting spring 12 when it rebounds, so that the originally depressed top frame 14 can rise and return to its original position.

[0027] In summary, compared with existing generator bases that only use springs as a shock-absorbing structure, this utility model is relatively simple and cannot solve the problem of vibration when the spring is compressed and rebounds, thus failing to serve as a good shock-absorbing component. This utility model not only sets up a multi-stage shock-absorbing structure composed of connecting springs and stepped rubber pads, but also sets up a hydraulic damper, which can effectively reduce the vibration generated by the connecting springs when they rebound.
