Description

Technical Field

[0001] The present invention relates to the technical field of generator noise reduction equipment, and particularly relates to a silent box for a generator set. Background Art

[0002] The problem of power shortage in our country is becoming more and more prominent, and at the same time, people's requirements for environmental protection are also getting higher and higher. As a backup power source for the power supply network, diesel generator sets with silent boxes are widely used because of their low noise. Especially as an essential emergency equipment for places with strict environmental noise requirements such as hospitals, hotels, high-end living communities, and large shopping malls. For high-power units, due to their relatively large noise, only by achieving a large noise reduction can the noise level of the unit meet the current environmental protection requirements. Therefore, a silent box with good noise reduction performance is of great significance for the development and use of generator sets;

[0003] The utility model with the publication number CN218542409U discloses a muffler for a diesel generator set silent box. When the generator set on the mounting plate vibrates, the mounting plate presses down the connecting rod, so that the sliding sleeve stretches the first spring along the sliding rod and simultaneously squeezes the second spring. When the first spring and the second spring return to their deformed states, the mounting plate moves upward, and the generator set pushes up the shock-absorbing column, effectively enhancing the shock-absorbing effect. The setting of the cooling water tank helps to accelerate the heat dissipation of the generator set and improve the working efficiency of the generator set. The cooperation of the base and the silent cover can effectively reduce noise. The noise of this utility model is low, it can accelerate heat dissipation, and at the same time has good shock-absorbing effect, effectively prolonging the service life of the generator set;

[0004] The above-mentioned prior art components have certain deficiencies in the actual use process. Although they achieve the shock-absorbing effect through the first spring and the second spring, the setting of the sliding rod and the sliding sleeve will cause the body to shake greatly under the influence of the vibration generated by the self-weight and operation process of the generator set, and thus it is prone to cause danger.

Detailed implementation manner

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-9 As shown in the figure, the present invention is a static sound box for a generator set, including an installation box 1. A sealing cover 11 is rotatably installed on the top surface of the installation box 1. A box body 20 is fixedly installed inside the installation box 1, and a guiding frame 35 is fixedly installed on the side surface of the box body 20;

[0030] Blocking blocks 22 are symmetrically and fixedly installed at the middle parts of the two long side surfaces of the box body 20. Sliding rods 23 are symmetrically and fixedly connected to the surfaces of the two blocking blocks 22. A limiting block 25 is sleeved and connected to the surface of the sliding rod 23. Springs 24 are symmetrically and fixedly connected to the upper and lower end surfaces of the limiting block 25. Among them, a damper is provided on the spring 24 to perform shock absorption by dissipating energy and reducing the resonance amplitude of the mechanical structure; an embedding block 31 penetrates through the surface of the limiting block 25. A top block 32 is fixedly connected to the top surface of the embedding block 31. A top frame 33 is fixedly connected to the surface of the top block 32. A backing plate 34 is fixedly connected to the top surface of the top frame 33;

[0031] An air inlet 2 is provided at the middle part of a long side surface of the installation box 1. A retaining net 3 is fixedly installed on the surface of the air inlet 2. A sound insulation cotton 4 is fixedly connected to the other long side surface inside the installation box 1. Hinges 5 are symmetrically and fixedly connected to the other long side surface of the air inlet 2. Side retaining frames 6 are fixedly connected to the two short side surfaces of the installation box 1;

[0032] Guiding openings 7 are symmetrically provided on the surface of the side baffle 6 near the upper and lower edge positions. Corrugated plates 8 are fixedly connected in a staggered and symmetric manner on the inner side of the side baffle 6 near the guiding openings 7. A sealing plate 9 is fixedly connected to the surface of the side baffle 6. A guiding head 10 is fixedly connected to the surface of one end of the sealing plate 9 at the middle position. During the normal operation of the generator set, the scattered and staggered corrugated plates 8 will increase the reflection of noise and extend the air duct distance on the basis of the existing structure, so as to effectively weaken the noise during the air outlet process and finally blow out from the guiding head 10, reducing the generation of noise while preventing large particle impurities from flowing into the inside of the side baffle 6 and blocking between the corrugated plates 8;

[0033] A detachable plate 12 is embedded in the top surface of the cover 11, and a mounting bracket 13 is embedded in the bottom end of the cover 11. A receiving groove is provided on the surface of the mounting bracket 13;

[0034] A telescopic frame 15 is movably embedded in the surface of the receiving groove. Positioning bolts 14 are equidistantly spirally connected to the surface of the mounting bracket 13 above the telescopic frame 15. Fixed connecting rods 16 are symmetrically fixedly connected to the surface of one end of the mounting bracket 13 at the middle position. A connecting shaft 17 penetrates through the middle position of the side surface of the fixed connecting rod 16. A movable connecting rod 18 is sleeved on the surface of the connecting shaft 17. A baffle 19 is fixedly connected to the top surfaces of the fixed connecting rod 16 and the movable connecting rod 18. During the installation and use of the generator set, according to its model size and power conditions, the user can manually control the extension length of multiple telescopic frames 15. Then, under the action of the baffle 19 and in cooperation with the connecting shaft 17, the connected movable connecting rods 18 are flipped by corresponding angles, so that the entire frame structure can be leaned against the vicinity of the box body 20 in a wrapped state. By covering the surface of the movable connecting rod 18 with sound insulation materials, the surrounding sound insulation effect can be improved, and thus the noise generated during the operation of the generator set can be specifically reduced;

[0035] There is a ventilation hole at the upper end of a long side surface of the box body 20, and an air outlet frame 21 is provided at the upper end of a short side surface of the box body 20. A positioning frame 26 is fixedly connected to the bottom surface inside the box body 20. A limiting frame 27 is fixedly connected to the surface of the positioning frame 26. A folding bracket 29 is embedded and connected to the surface of the limiting frame 27. A cylinder 28 is rotatably connected to the bottom end inside the box body 20. The cylinder 28 is fixedly connected to the folding bracket 29. The upper end of the folding bracket 29 is fixedly connected with a limiting sleeve 30. The limiting sleeve 30 is sleeved and connected with an embedded block 31. After the generator set is fixedly installed on the surface of the cushion plate 34, according to its model size, the user can control the operation of the cylinder 28, and then control the folding bracket 29 to lift a certain height so that its approximate position can match the ventilation hole and the air outlet frame 21 to achieve the maximum heat dissipation effect. During the operation of the generator set, the generator set will inevitably generate vibrations that are transmitted to the top frame 33 through the cushion plate 34. The embedded block 31 connected thereto will disperse the vibrations to the limiting blocks 25 at both ends through the embedded block 31. Under the limiting action of the blocking block 22 and the limiting sleeve 30, the vibration range of the embedded block 31 will be limited first to avoid violent shaking of the generator set. During this process, the springs 24 located at the upper and lower ends of the limiting blocks 25 assist in buffering, thereby reducing the impact of vibrations on the machine body and reducing the generation of noise;

[0036] Positioning seats 36 are symmetrically and fixedly connected to the side surface of the guiding frame 35. A linkage shaft is rotatably connected to the surface of the positioning seat 36. A clamping block 37 is clamped and fixed to the surface of the linkage shaft. A convex block 38 is fixedly connected to the surface of the clamping block 37. A connecting bar 39 is sleeved and connected to the surface of the convex block 38. A motor 40 is fixedly connected to the surface of one of the positioning seats 36. A wind blocking plate 41 is sleeved and connected to the surface of the linkage shaft. Through holes 42 are provided on the surface of the wind blocking plate 41. A connecting block 43 is fixedly connected to one end surface of the linkage shaft. When the generator set operates at low power, at this time each wind blocking plate 41 is relatively horizontally arranged, and the heat dissipation requirements can be met only through the through holes 42. At the same time, moisture and dust entering the inside of the box body 20 can be effectively reduced, and the generation of noise can be reduced. When the generator set needs to operate at high power, the user can control the operation of the motor. Under its driving action, multiple linkage shafts will be linked under the action of the clamping block 37, the convex block 38 and the connecting bar 39, so that multiple groups of wind blocking plates 41 rotate by the same angle around the connecting block 43, maximizing the air intake area to meet the heat dissipation needs of the generator set.

[0037] Working principle of the present invention: During the normal operation of the generator set, the dispersed and staggered corrugated plates 8 will increase the reflection of noise and extend the air duct distance based on the existing structure, thereby effectively weakening the noise during the air outlet process and finally blowing it out from the guide head 10, so that the noise is reduced while preventing large particles of impurities from pouring into the side baffle frame 6 to cause blockage between the corrugated plates 8. During the installation and use of the generator set, according to its model size and power, the user can manually control the extension length of multiple telescopic frames 15, and then under the action of the baffle 19, the connected active connecting rod 18 is turned to a corresponding angle in cooperation with the connecting shaft 17, so that the entire frame structure can be wrapped and leaned against the box body 20. By coating the surface of the active connecting rod 18 with sound insulation material, the surrounding sound insulation effect can be improved, thereby specifically reducing the noise generated during the operation of the generator set. After the generator set is fixedly installed with the pad 34 surface, according to its model size, the user can control the operation of the cylinder 28, and then control the folding bracket 29 to lift a certain height, so that its approximate position can match the ventilation hole and the air outlet frame 21, so as to achieve the best The invention has a great heat dissipation effect. When the generator set is in operation, the generator set will inevitably generate vibrations. When the vibrations are transmitted to the top frame 33 through the pad 34, the embedded block 31 connected thereto will disperse the vibrations to the limit blocks 25 at both ends through the embedded block 31. Under the limiting action of the blocking block 22 and the limit sleeve 30, the vibration range of the embedded block 31 will be limited first to prevent the generator set from shaking violently. In this process, the springs 24 at the upper and lower ends of the limit blocks 25 assist in the buffering effect, thereby reducing the impact of the vibrations on the machine body and reducing the noise. When the group operates at low power, each wind blocking plate 41 is relatively horizontally arranged, and the heat dissipation demand can be met only through the through hole 42. At the same time, it can effectively reduce the entry of moisture and dust into the box body 20 and reduce the generation of noise. When the generator set needs to operate at high power, the user can control the operation of the motor. Under its driving action, multiple linkage shafts will be linked under the action of the clamping block 37, the protrusion 38 and the connecting bar 39, so that multiple groups of wind blocking plates 41 are flipped around the connecting block 43 at the same angle, maximizing the air inlet area to meet the heat dissipation needs of the motor set.

[0038] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
