[0018] 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.
[0019] Reference Figures 1-3 The present invention provides an embodiment of a base for vibration reduction and noise reduction, comprising a base 1, a support plate 2 fixedly connected to the outer wall of the base 1, a mounting seat 5 fixedly connected to the outer wall of the base 1, a mounting plate 7 fixedly connected to the top of the mounting seat 5, a spring 6 disposed inside the mounting seat 5, one end of the spring 6 fixedly connected to the top of the mounting seat 5, and the other end of the spring 6 fixedly connected to the bottom of the mounting plate 7. The spring 6, together with the mounting seat 5 and the mounting plate 7, can perform the most basic vibration reduction treatment on the base 1. The base 1 is provided with a vibration reduction component. The shock absorption assembly includes a top plate 8, the outer wall of which is slidably connected to the inner wall of the base 1. A guide rod 9 is fixedly connected to the bottom of the top plate 8. A cylinder 16 is fixedly connected to the bottom of the guide rod 9. A guide rod 14 is fixedly connected to the bottom of the cylinder 16. A guide rod 12 is fixedly connected to the bottom of the guide rod 14. A base column 13 is fixedly connected to the bottom of the guide rod 12. A spring 10 is provided on the outer wall of the cylinder 16. The compression spring 10 is used for buffering, which can buffer the top plate 8 and the base 1. The two ends of the spring 10 are fixedly connected to the two ends of the pad 28. Reference Figures 1-4 An oil seal 15 is fixedly connected to one side of the cylinder 16. A piston 18 is slidably connected inside the cylinder 16. Multiple hydraulic holes 19 are opened inside the piston 18. Hydraulic oil flows out from the hydraulic holes 19 as the piston 18 moves up and down, providing a buffering effect. A connecting post 17 is fixedly connected inside the piston 18. A gasket 20 is fixedly connected to one side of the piston 18, blocking two of the hydraulic holes 19, making it easy to compress but difficult to stretch. A guide post 21 is fixedly connected inside the cylinder 16. A spring 29 is installed on one side of the gasket 20. One end of the spring 29 is fixedly connected to the bottom of the gasket 20, and the other end is fixed to the top of the guide post 21. The top plate 8 is located at the top. A water pump 3 is fixedly connected, and a motor 4 is fixedly connected to the top of the top plate 8. A sleeve 11 is rotatably connected to the drive end of the motor 4. A fixed plate 22 is fixedly connected to one end of the sleeve 11. The fixed plate 22 is the basic load-bearing structure for shock absorption and provides an installation and limiting platform for shock absorption components such as spring 3 26 and guide column 27. A connecting plate 23 is fixedly connected to one side of the fixed plate 22. A ball head 24 is fixedly connected to the outer wall of the connecting plate 23. A gasket 25 is fixedly connected to the bottom end of the ball head 24. A guide column 27 is fixedly connected to one end of the gasket 25. A spring 3 26 is provided on the outer wall of the guide column 27. The two ends of the spring 3 26 are fixedly connected to the outer ends of the gasket 25. The spring 3 26 absorbs the vibration energy during the operation of the equipment through elastic expansion and contraction, effectively attenuating the vibration amplitude.
[0020] Working principle: When using this type of base for vibration reduction and noise reduction, the bottom column 13 of the vibration damping component is first fixed horizontally inside the base 1. The bottom column 13 is fixed to the bottom end of the guide rod 14. When subjected to external force, the guide rod 9 will drive the pad 28 to compress the spring 10 for initial buffering. The hydraulic component at the bottom of the pad 28 contains a cylinder 16, and hydraulic oil is placed inside the cylinder 16. When subjected to external force, the hydraulic oil can fall from the four hydraulic holes 19 of the piston 18 to the bottom of the cylinder 16. When the hydraulic oil rises, only two of the hydraulic holes 19 can rise due to the obstruction of the pad 20. This makes the overall structure easy to compress and difficult to stretch. The spring 10 outside the cylinder 16 further reduces the vibration effect.
[0021] When using this type of base for vibration reduction and noise reduction, power is transmitted to the fixed plate 22 through the sleeve 11. When the system vibrates, the spring 26 can absorb vibration energy through elastic extension and contraction. The guide post 27 and the matching gasket 25 can limit the deformation direction of the spring 26 to prevent it from deflecting or getting stuck. At the same time, the fixed plate 22, the connecting plate 23, and the sleeve 11 work together to effectively buffer the vibration during the power transmission process, thereby achieving vibration reduction protection for the connection parts.
[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
