Detailed Implementation

[0025] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] In this invention, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its normal use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0027] See Figure 1-4 The noise reduction base shown includes a frame with a through hole running vertically through the center of the frame. A buffer mechanism is provided inside the through hole. Multiple clamping mechanisms are provided around the circumferential direction of the through hole at the upper end of the frame. These mechanisms cooperate with each other and clamp towards the center of the through hole.

[0028] By implementing the above technical solution, the noise reduction base is installed at the bottom of the equipment that needs noise reduction. When the equipment shakes, it can effectively reduce vibration and thus reduce noise generation.

[0029] When in use, place the noise reduction base at the bottom of the processing equipment. Specifically, place the processing equipment on the buffer mechanism and clamp the equipment with multiple clamping mechanisms to prevent the equipment from sliding to the side. The buffer mechanism can slide vertically in the through hole, thereby buffering the equipment in the vertical direction and reducing noise.

[0030] To further provide a frame structure, the frame includes a first support plate 11 and a second support plate 14 coaxially disposed above the first support plate 11 and connected to it. A through hole is provided through both the first support plate 11 and the second support plate 14. This design achieves overall weight reduction. Furthermore, the double-layer structure of the first support plate 11 and the second support plate 14 creates a hollow center, allowing visibility of the buffer mechanism. This facilitates observation of the noise-reducing base's operational status after it is put into use. Additionally, a dynamic monitoring device can be installed on one side to collect real-time data on the buffer mechanism's operation, enabling immediate notification of staff in case of any abnormalities.

[0031] To further provide a connection method between the first support plate 11 and the second support plate 14, the first support plate 11 and the second support plate 14 are connected by a plurality of connecting posts 12. For example... Figure 1 As shown, there are 4 connecting columns 12, which are evenly spaced.

[0032] In this embodiment, screws are provided at both ends of the connecting column 12, and the end faces of the first support plate 11 and the second support plate 14 facing away from each other are each provided with a first groove. The screws pass through the corresponding first support plate 11 or second support plate 14 and extend into the first groove, where they are locked by nuts 23.

[0033] This design allows for a detachable connection between the connecting column 12 and the first support plate 11 and the second support plate 14. During installation, it is only necessary to tighten the nuts 23 at both ends. In addition, the first groove is designed to hide the nuts 23, preventing them from protruding from the first support plate 11 or the second support plate 14.

[0034] In this embodiment, the end faces of the first support plate 11 and the second support plate 14 facing each other are each provided with a second groove for limiting the connecting post 12. With this arrangement, the shoulder surfaces of both ends of the connecting post 12 are embedded into the second groove, preventing lateral swaying.

[0035] In this embodiment, to further provide a clamping mechanism, the clamping mechanism includes a locking threaded block 16 and a threaded rod 17 disposed within the locking threaded block 16 and extending radially along the through hole. For example... Figure 1 In one embodiment shown, four locking threaded blocks 16 are circumferentially spaced, and the clamping degree is adjusted by adjusting the feed length of the threaded rod 17 toward the through hole.

[0036] In this embodiment, to further provide a buffering mechanism, the buffering mechanism includes a first pressure plate 19, above which a damping spring 18 and a damping plate 15 are sequentially arranged. The upper end face of the damping plate 15 is flush with the upper end face of the frame. The frame is provided with a first locking hole 13 extending radially through it, and the first pressure plate 19 is provided with a second locking hole corresponding to the first locking hole 13. Locking pins are detachably inserted into the first locking hole 13 and the second locking hole. The damping plate 15 fits into the through hole on the second support plate 14, and the upper end of the damping plate 15 is flush with the upper end of the second support plate 14. A spring groove is provided at the bottom of the damping plate 15, and the upper end of the damping spring 18 is disposed in the spring groove. Thus, when the damping plate 15 is subjected to pressure, it can be buffered by the damping spring 18. Before use, the locking pin is inserted into the first locking hole 13 and the second locking hole to fix the first pressure plate 19.

[0037] Furthermore, a friction spring 22 and a second pressure plate 20 are sequentially arranged at the lower end of the first pressure plate 19, and a friction plate 21 is arranged at the lower end of the second pressure plate 20. The friction spring 22, the second pressure plate 20, and the friction plate 21 work together, allowing the friction plate 21 to make frictional contact with the ground, increasing the frictional force with the ground, preventing relative movement of the first support plate 11, and thus preventing slippage due to equipment shaking. Additionally, when the friction spring 22, the second pressure plate 20, and the friction plate 21 are provided, the locking pin can be pulled out, causing the first pressure plate 19 to be linked with the friction spring 22.

[0038] A second aspect of the present invention provides a noise reduction system applied to the aforementioned noise reduction base. The noise reduction system includes a collection module, a processing module, an output module, and a speaker, which are electrically connected in sequence. The output module and the speaker are mounted on the frame. The collection module and the processing module can be installed on the upper part of the factory building. The collection module collects noise, the processing module processes the noise, the output module outputs a reverse sound wave, and the speaker plays the reverse sound wave. The processing module in this noise reduction system can generate a reverse sound wave corresponding to the noise through a processor, thereby neutralizing and eliminating the noise. Real-time noise reduction operation can be performed based on noise feedback. The processing module and the output module are connected by a signal, such as a wireless network.

[0039] like Figure 5 As shown, a third aspect of the present invention provides a noise reduction method for a noise reduction base, the noise reduction method employing the aforementioned noise reduction system, comprising the following steps:

[0040] S1, noise is collected through the collection module;

[0041] S2, noise reduction is performed through the processing module;

[0042] S3, through the output module, enables the speaker to emit inverse sound waves for noise cancellation.

[0043] In one embodiment, when installing the noise-reducing base, the device's support feet are placed on the vibration damping plate 15. The locking pins in the first locking hole 13 and the second locking hole are pulled out, and the threaded rod 17 is turned to clamp the support feet. When the device shakes, the vibration damping spring 18 can dampen the vibration. The greater the shaking amplitude, the greater the descent of the vibration damping plate 15, causing the first pressure plate 19 to descend. This, in turn, allows the second pressure plate 20 and the friction plate 21 to adhere tightly to the ground under the action of the friction spring 22, preventing movement. When noise is generated due to the device's shaking, the noise is collected by the collection module, processed by the processing module, and then the output module on the first support plate 11 emits a reverse sound wave to neutralize and eliminate the noise.

[0044] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0045] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.

[0046] Furthermore, various different embodiments of the present invention can be combined in any way, as long as they do not violate the spirit of the present invention, they should also be regarded as the content disclosed by the present invention.
