Description

Technical Field

[0001] This utility model relates to the field of diesel generator technology, and in particular to an adjustable vibration damping base for a diesel generator set. Background Technology

[0002] A diesel generator is a small power generation device that uses diesel fuel and a diesel engine as the prime mover to drive a generator to generate electricity. A complete unit typically consists of a diesel engine, generator, control box, fuel tank, starting and control batteries, protection devices, emergency cabinet, and other components. It can be used for daily power generation and emergency power generation in various homes, offices, and businesses of all sizes.

[0003] Currently, when diesel generator sets are in operation, the engine running and the electromagnetic force of the generator generate significant vibrations. These vibrations are transmitted to the mounting foundation, affecting not only the surrounding environment but also causing fatigue damage to the generator set's components, reducing the equipment's lifespan and stability. To address this vibration issue, a vibration-damping base is added to the bottom of the diesel generator. However, existing vibration-damping bases generally lack height adjustment functionality. When using a vibration-damping base for direct support, the entire diesel generator lacks mobility. Therefore, there is an urgent need to design an adjustable vibration-damping base for diesel generator sets to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an adjustable vibration damping base for diesel generator sets. Its advantages include reducing the impact of vibration on the surrounding environment and equipment, and allowing for height adjustment of the support platform to facilitate vibration damping and relocation of the diesel generator set, thereby improving the base's versatility and adaptability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable vibration damping base for a diesel generator set includes:

[0007] Diesel generator body;

[0008] A support frame, which is mounted on the diesel generator body;

[0009] Two fixing frames are fixed to both sides of the support frame;

[0010] Both fixed frames are equipped with movable support platforms, and positioning components are provided between the support platforms and the fixed frames. Damping spring dampers are installed on both sides of the bottom of the two support platforms, and the bottom of the damping spring dampers is equipped with the same base.

[0011] The above technical solutions can effectively attenuate the vibration generated during the operation of diesel generator sets, reducing the impact of vibration on the surrounding environment and equipment.

[0012] The present invention is further configured such that the positioning component includes a longitudinally opened through-hole in the middle of the support platform, and the bottom end of the fixing frame passes through the interior of the through-hole. A fixing groove is opened laterally in the middle of the support platform, and two positioning grooves are opened at the bottom end of the fixing frame. The same positioning block is inserted into the inner wall of one of the positioning grooves and the inner wall of the fixing groove.

[0013] The present invention is further configured such that a handle is fixed to one end of the positioning block, and a connection hole is provided at both ends of one side of the handle, and a return spring passing through the connection hole is installed at both ends of the inner wall of the other side of the handle and one side of the support platform.

[0014] The above technical solutions enable the support platform to be height-adjustable, thereby facilitating the adjustment of the base height and improving the base's versatility and adaptability.

[0015] The present invention is further configured such that a first guide hole is provided at both ends of the top of the support platform, and a first guide sleeve is fixed to the inner wall of the first guide hole, and the first guide sleeve is sleeved on the outer wall of the support frame.

[0016] The above technical solutions make the up-and-down movement of the support platform smoother, improving the stability and reliability of the vibration damping base.

[0017] The present invention is further configured such that guide posts are fixed at the top four corners of the base, and two second guide holes are opened on the two support platforms. A second guide sleeve is fixed on the inner wall of the second guide hole, the guide post passes through the second guide sleeve, and buffer springs are installed at the top four corners of the base and the bottom of the support platform, and the buffer springs are sleeved on the outer wall of the guide post.

[0018] The above technical solutions further buffer the vibration between the support platform and the base, and reduce the impact of vibration through their own compression and extension, thereby protecting the diesel generator body from vibration damage.

[0019] The present invention is further configured such that universal wheels are installed at the four corners of the bottom of the diesel generator body, and two grooves are opened on both sides of the base, with the universal wheels located in the grooves, and the bottom surface of the base is lower than the bottom surface of the universal wheels.

[0020] The above technical solutions make diesel generators easy to move.

[0021] The present invention is further configured such that the base is composed of a top plate, a vibration damping layer and a bottom plate from top to bottom, and both the top of the top plate and the bottom of the bottom plate are provided with wear-resistant layers.

[0022] The above technical solutions enhance the wear resistance of the base by adding a wear-resistant layer, reducing damage caused by long-term use or friction with the ground, and extending the service life of the base.

[0023] The present invention is further configured such that the vibration damping layer has multiple cavities inside, and air guide holes are provided between two adjacent cavities, and an air inlet extending from the top plate and the wear-resistant layer is provided at the top of one of the cavities.

[0024] By using the above technical solutions, the hardness and elasticity of the damping layer can be changed to adapt to different vibration frequencies and intensities, thereby further improving the damping effect.

[0025] The beneficial effects of this utility model are as follows:

[0026] This invention effectively attenuates vibrations generated during the operation of a diesel generator set by installing a damping spring vibration damper at the bottom of the support platform and setting a buffer spring between the base and the support platform, thereby reducing the impact of vibration on the surrounding environment and equipment. The design of the positioning component allows the support platform to be height-adjusted on the fixed frame through the cooperation of positioning blocks and positioning slots, which facilitates the adjustment of the base height and allows the casters to contact and disengage from the ground, making it easier to reduce vibration and move the diesel generator set, and improving the versatility and adaptability of the base.

[0027] This utility model adopts a composite structure of a top plate, a vibration damping layer, and a bottom plate for the base. The surfaces of the top plate and the bottom plate are provided with wear-resistant layers, which not only improves the vibration damping capacity of the base, but also enhances the wear resistance and service life of the base. At the same time, the vibration damping layer has multiple cavities and air vents inside. The cavities can be inflated through the air inlet to further adjust the vibration damping effect to meet different vibration damping needs, thereby improving the flexibility and adjustability of the vibration damping base.

[0035] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0036] Reference Figures 1-6 This utility model provides an adjustable vibration damping base for a diesel generator set, comprising:

[0037] Diesel generator body 1;

[0038] Support frame 2 is mounted on diesel generator body 1;

[0039] Two fixing frames 3 are fixed on both sides of the support frame 2 respectively;

[0040] Each of the two fixed frames 3 is movably equipped with a support platform 4, and a positioning component 5 is provided between the support platform 4 and the fixed frame 3. The positioning component 5 includes a through-hole 13 longitudinally opened in the middle of the support platform 4, and the bottom end of the fixed frame 3 passes through the interior of the through-hole 13. A fixing groove 504 is transversely opened in the middle of the support platform 4, and two positioning grooves 501 are opened at the bottom end of the fixed frame 3. The inner wall of one positioning groove 501 and the inner wall of the fixing groove 504 are connected to the same positioning block 503. A handle 502 is fixed to one end of the positioning block 503, and a connecting hole 505 is opened at both ends of one side of the handle 502. A return spring 506 passing through the connecting hole 505 is installed at both ends of the inner wall of the other side of the handle 502 and the support platform 4. Damping spring vibration dampers 6 are installed on both sides of the bottom of each support platform 4, and the same base 7 is installed on the bottom of each damping spring vibration damper 6. Universal wheels 10 are installed at the four corners of the bottom of the diesel generator body 1. Two grooves 9 are opened on both sides of the base 7, and the universal wheels 10 are located in the grooves 9. The bottom surface of the base 7 is lower than the bottom surface of the universal wheels 10. Through the damping spring vibration dampers 6, the vibration generated by the diesel generator set during operation can be effectively attenuated, reducing the impact of vibration on the surrounding environment and equipment. The positioning component 5 allows the support platform 4 to be height-adjusted, so as to adjust the height of the base 7, allowing the universal wheels 10 to contact and disengage from the ground, facilitating the vibration reduction and movement operation of the diesel generator set, and improving the versatility and adaptability of the base 7.

[0041] To improve stability, refer to Figures 1-4 The support platform 4 has first guide holes 14 at both ends of its top, and first guide sleeves 12 are fixed to the inner walls of the first guide holes 14. The first guide sleeves 12 are fitted onto the outer walls of the support frame 2, making the up-and-down movement of the support platform 4 more stable and improving the stability and reliability of the base 7.

[0042] To achieve further buffering, refer to Figure 1 , Figure 2 and Figure 4 The base 7 has guide posts 8 fixed at the top four corners, and two second guide holes 16 are opened on the two support platforms 4. The inner wall of the second guide hole 16 is fixed with a second guide sleeve 15. The guide posts 8 pass through the second guide sleeve 15. The base 7 has buffer springs 11 installed at the top four corners and the bottom of the support platform 4. The buffer springs 11 are sleeved on the outer wall of the guide posts 8. The buffer springs 11 further buffer the vibration between the support platform 4 and the base 7. The impact force of the vibration is reduced by its own compression and extension, thereby protecting the diesel generator body 1 from vibration damage.

[0043] To further improve the vibration reduction effect, refer to Figure 6The base 7 is composed of a top plate 701, a vibration damping layer 702, and a bottom plate 706 arranged from top to bottom. Both the top of the top plate 701 and the bottom of the bottom plate 706 are provided with wear-resistant layers 707. The vibration damping layer 702 has multiple cavities 703 inside, and air guide holes 705 are provided between two adjacent cavities 703. The top of one of the cavities 703 is provided with an air inlet 704 that extends out from the top plate 701 and the wear-resistant layer 707. By inflating the cavity 703 with air through the air inlet 704, the hardness and elasticity of the vibration damping layer 702 can be changed to adapt to different vibration frequencies and intensities, thereby further improving the vibration damping effect. At the same time, the wear-resistant layer 707 can enhance the wear resistance of the base 7, reduce damage caused by long-term use or friction with the ground, and extend the service life of the base 7.

[0044] Working principle: The diesel generator set will generate vibration during operation. The damping spring damper 6 and the buffer spring 11 are used to reduce the impact of the vibration and protect the diesel generator body 1 from vibration damage. Multiple cavities 703 and air vents 705 are provided inside the damping layer 702 of the base 7. By inflating the cavity 703 with air through the air inlet 704, the hardness and elasticity of the damping layer 702 can be changed to adapt to different vibration frequencies and intensities, further improving the vibration damping effect. At the same time, the wear-resistant layer 707 on the surface of the top plate 701 and the bottom plate 706 can enhance the wear resistance of the base 7, reduce the damage caused by long-term use or friction with the ground, and extend the service life of the base 7.

[0045] When movement is required, the handle 502 is pulled to disengage the positioning block 503 from the current positioning slot 501. At this time, the support platform 4 can move on the fixed frame 3. After moving to the appropriate position, the handle 502 is released, and the return spring 506 will push the handle 502 and the positioning block 503 to reset, so that the positioning block 503 is inserted into the corresponding positioning slot 501, thereby adjusting the position of the support platform 4 and adjusting the height of the base 7, so that the caster wheel 10 contacts the ground, making it convenient to move the entire diesel generator.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
