[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See attached Figure 1-5 ;

[0028] A noise reduction device for surrounding noise control, characterized in that: it includes a mounting base plate 1 for mounting and placing a noise source, a control panel 2 is mounted on the front end surface of the mounting base plate 1, and two mutually adjustable silencer frames 8 are mounted on the upper end surface of the mounting base plate 1, and silencer components are respectively mounted in the silencer frames 8, and the silencer components respectively include side blocks 12, sound absorbing panels 15 and silencer panels 11 which are sequentially mounted from the inside to the outside, and through holes 13 are distributed on the side blocks 12, and the position of the silencer frames 8 is driven by the screw rod assemblies on both sides, and the two silencer frames 8 are connected and fixed by fastening connecting frames after being moved into position. The noise emitted by the whole can be reduced by the silencer assembly and the fastening connection frame, and the overall noise reduction effect is relatively complete, avoiding the previous situation that only one position can be reduced. When reducing noise, the noise source will be in the adapter groove 10 of the beam silencer frame 8, and the noise will enter the interior of the silencer plate 11 through the through hole 13. The noise can be reduced by the design of the sound absorbing plate 15 and the honeycomb sound absorbing block 16. The overall noise reduction effect is good, and the noise is surrounded by the structure of the fastening connection frame to reduce the leakage of noise.

[0029] Further, the muffler assembly is located at the rear end face position in the muffler frame 8, and the muffler frame 8 and the side block 12 enclose an adaptation cavity 10 for accommodating the noise source. A honeycomb sound absorbing block 16 is arranged inside the sound absorbing board 15. A concave cavity is arranged on the front end face of the muffler board 11, and the sound absorbing board 15 and the side block 12 are sequentially inserted into the concave cavity. The muffler frame 8 includes an outer frame 81, an inner frame 82, and a sound insulation layer 83 therebetween.

[0030] Furthermore, the fastening connection frame is composed of a plurality of connection plates 17. The outer edge surface of the muffler frame 8 is provided with a connection rib 14. The inner end surface of the connection plate 17 is provided with slots 18 arranged at intervals. The slots 18 are snap-fitted with the connection rib 14. The gap between the connection plates 17 is adjusted to provide connection, transmission or heat dissipation for the noise source. When the noise source needs to be connected to an external component or when heat dissipation is required, the combined structure of the fastening connection frame can be fully applied according to the actual situation. When encountering the above situation, the fully enclosed structure is not completely sealed, and a gap is opened to connect the external component to the noise source and to dissipate heat. Compared with the traditional non-enclosed structure, the noise reduction effect has substantial characteristics and progress. The connection plate 17 includes an outer plate body, an inner plate body and a sound insulation layer therebetween, which enhances the sound insulation effect.

[0031] Furthermore, the screw assembly includes a bidirectional screw 5 rotatably mounted on the mounting base plate 1, and guide blocks 4 and 6 are respectively mounted on one side of the muffler frame 8 to guide and cooperate with the bidirectional screw 5, and the rotation of the bidirectional screw 5 is driven by the motor 7 at the end. The noise source is placed on the top surface of the base plate 1, and then the motor 7 is started, and the motor 7 drives the limit block 6 to rotate, so that the limit block 4 and the limit block 6 will approach each other, and the movement trajectory of the two limit blocks 4 and 6 is guided and limited by the limit groove 3 set on the base plate 1 to ensure their stable movement.

[0032] The control panel 2, bidirectional screw rod 5, motor 7, silencer plate 11 and honeycomb sound absorbing block 16 in the above structure are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to technicians in this field, so they will not be repeated here.

[0033] Working principle: When the staff uses this device, first connect the device to an external power supply to provide power support for the device, first place the noise source on the top surface of the bottom plate 1, and then start the motor 7, the motor 7 will drive the limit block 6 to rotate, so that the limit block 4 and the limit block 6 will be close to each other, and the movement trajectory of the limit block 4 and the limit block 6 will be limited by the limit groove 3 to ensure their stable movement, and then the limit block 4 and the limit block 6 will drive the silencer frame 8 and the silencer frame 14 to move, so that the silencer frame 8 and the silencer frame 14 are connected by a fastening connecting frame to form an enclosing mechanism, so that the noise generated by the noise source can be effectively reduced in the chamber of the silencer frame 8, the silencer frame 14 and the fastening connecting frame combination.

[0034] When noise reduction is performed, the noise source will be limitedly installed in the adapter groove 10 inside the silencer frame 8 and the silencer frame 14, and the noise will enter the interior of the silencer plate 11 through the through hole 13. The noise can be eliminated through the design of the sound absorbing plate 15 and the honeycomb sound absorbing block 16, and the overall noise reduction effect is good. At the same time, when the silencer frame 8 and the silencer frame 14 are adjusted to a suitable position, the silencer frame 8 and the silencer frame 14 can be connected again through the fastening connection frame.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
