In the process of cooling the photovoltaic inverter or energy storage converter, very high noise will also be generated. The noise inside the machine can easily spread to the external environment, causing serious sound leakage and sound pollution.

In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0050] The embodiments of the utility model provide a sound-absorbing structure, equipment and light storage system, which can help reduce the noise at the air inlet and / or air outlet, reduce sound leakage and sound pollution, and benefit the normal life and physical and mental health of residents.

[0051] like Figures 1 to 13 As shown, the embodiment of the utility model provides a sound-absorbing structure 100, and the sound-absorbing structure 100 is installed at the air inlet 211 and / or the air outlet 212, such as Figures 1 to 8 This is a schematic diagram of an embodiment in which the noise reduction structure 100 is installed at the air inlet 211. Figures 9 to 13 The schematic diagram of an embodiment in which the sound-absorbing structure 100 is installed at the air outlet 212 is shown. The sound-absorbing structure 100 includes: an outer frame 110, a baffle 120 and a first sound-absorbing part 130. The edge of the outer frame 110 is composed of an arc segment, a plurality of continuous straight line segments, or an arc and a straight line segment. The baffle 120 includes a plurality of cavities, which are formed by the abutment of one end of the first baffle 121 and / or the second baffle 122 with the outer frame 110. The inclination angle of the second baffle 122 relative to the air inlet 211 and / or the air outlet 212 is greater than or equal to 0° and less than or equal to 180°. The first sound-absorbing part 130 covers the baffle 120.

[0052] The technical solution of the utility model adopts a sound-absorbing structure 100 including a baffle 120 and a first sound-absorbing part 130 provided at the air inlet 211 and / or the air outlet 212, and the first sound-absorbing part 130 covers the baffle 120, so as to reduce the noise at the air inlet 211 and / or the air outlet 212. The inclination angle of the second baffle 122 relative to the air inlet 211 and / or the air outlet 212 is greater than or equal to 0° and less than or equal to 180°, so that the cross-sectional areas of the multiple air duct openings formed by the second baffle 122 dividing the interior of the sound-absorbing structure 100 are different, which can increase the number of reflection superpositions of sound waves in the air inlet 211 and / or the air outlet 212, thereby increasing the sound-absorbing effect, which is beneficial to reduce the noise at the air inlet 211 and / or the air outlet 212.

[0053] like Figures 1 to 3 as well as Figures 9 to 13As shown, the barrier 120 includes: at least one first baffle 121 and / or at least one second baffle 122. The first baffle 121 is connected to the outer frame 110 at both ends to form a plurality of cavities arranged horizontally. The second baffle 122 is connected to the outer frame 110 at both ends to form a plurality of cavities arranged vertically.

[0054] like Figures 1 to 3 as well as Figures 9 to 13 As shown, the barrier portion 120 includes: at least two first partitions 121 and / or at least two second partitions 122, two adjacent first partitions 121 and second partitions 122 are arranged at intervals, one end of each first partition 121 and second partition 122 is abutted against the outer frame 110, and the first partitions 121 and the second partitions 122 are arranged to intersect with each other to form a plurality of cavities.

[0055] like Figures 1 to 13 As shown, the edge of the second partition 122 is composed of an arc segment, a plurality of continuous straight segments, or an arc and a straight segment. The arc of the edge of the outer frame 110 and the arc of the second partition 122 can be an arc plate or a flat plate formed by bending several times.

[0056] like Figures 9 to 13 As shown, at the air outlet 212, the second partition 122 is connected to the outer frame 110 to divide the interior of the sound-absorbing structure 100 into multiple layers of sound-absorbing channels, and the length of each layer of sound-absorbing channels in the extension direction of the second partition 122 is the same or different. At the air inlet 211, the second partition 122 can also be connected to the outer frame 110 to divide the interior of the sound-absorbing structure 100 into multiple layers of sound-absorbing channels, and the length of each layer of sound-absorbing channels in the extension direction of the second partition 122 is the same or different.

[0057] In summary, if Figures 1 to 13As shown, in the present utility model application, the first partition 121 and the second partition 122 in the barrier 120 do not have to exist at the same time. There may be only the first partition 121, or only the second partition 122, or the first partition 121 and the second partition 122 may exist at the same time. Therefore, in the present utility model application, the barrier 120 includes at least five embodiments, namely: only the first partition 121; or only the second partition 122; or the first partition 121 and the second partition 122 are provided at the same time; or the first partition 121 is used to divide the interior into multiple columns of silencer channels arranged left and right, and the second partition 122 divides the N-1 columns of silencer channels; or the second partition 122 is used to divide the interior into N layers of silencer channels arranged up and down, and the first partition 121 divides the N-1 layers of silencer channels. In the application of the utility model, there is no limitation on the number and specific arrangement of the first partition 121 and the second partition 122. Those skilled in the art can set the number and specific arrangement of the first partition 121 and the second partition 122 according to actual needs to achieve a good sound insulation effect.

[0058] like Figures 1 to 3 as well as Figures 9 to 13 As shown, at least one second partition 122 is arranged non-parallel to the surface of the outer frame 110, so that the cross-sectional areas of the openings of the multiple muffler channels formed by the second partition 122 dividing the interior of the muffler structure 100 are different. Figures 6 to 8 As shown, the inclination angles of the second partition 122 relative to the air inlet 211 are 120°, 90°, and 85°, respectively. The technical solution of the utility model makes the second partition 122 and the surface of the outer frame 110 non-parallel to each other, or sets an inclination angle between the second partition 122 and the air inlet 211, so that the cross-sectional areas of the multiple air duct openings formed by the internal division of the sound-absorbing structure 100 are different, which can increase the number of reflection and superposition of sound waves in the sound-absorbing structure 100, thereby increasing the sound-absorbing effect, which is beneficial to noise reduction in the sound-absorbing structure 100. The cross-sectional area in the cavity becomes smaller and the sound group of the air duct becomes higher, which can increase the dissipation effect of sound waves in the sound-absorbing structure 100, while the total ventilation area remains basically unchanged and does not affect ventilation.

[0059] In the present utility model application, the first sound absorbing part 130 can be arranged on the first partition 121 and / or the second partition 122 of the baffle part 120 by gluing, screw fixing, bead fixing, etc., to prevent the first sound absorbing part 130 from aging and falling off. The first sound absorbing part 130 can be sound absorbing cotton. Figure 4 As shown, the first sound absorbing part 130 is fixed between the pressure strip 123 and the first partition plate 121, and the pressure strip 123 and the first partition plate 121 are fixed by fasteners 124 to press the first sound absorbing part 130 to prevent it from falling off. The fasteners 124 can be screws or bolts. Figure 5As shown, a hole may also be opened on the first sound absorbing part 130, and the fastener 124 may directly pass through the pressure strip 123, the first sound absorbing part 130 and the second partition 122 to fix the first sound absorbing part 130 to prevent the first sound absorbing part 130 from falling off. Further, in practical applications, the first sound absorbing part 130 may also be arranged on the second partition 122. The present application does not limit the specific installation method and installation position of the first sound absorbing part 130. Those skilled in the art can determine the specific installation method and installation position of the first sound absorbing part 130 according to actual needs to achieve a good sound reduction effect.

[0060] like Figures 14 to 20 As shown, the embodiment of the utility model further provides a silencer device 200. The silencer device 200 includes: a silencer structure 100 according to any of the aforementioned embodiments of the utility model and a main air duct 210. The silencer structure 100 includes: an outer frame 110, a baffle portion 120 and a first sound absorbing portion 130, and the edge of the outer frame 110 is composed of an arc segment, a plurality of continuous straight line segments, or an arc line and a straight line segment connected in coordination. The baffle portion 120 includes a plurality of cavities, and the cavity is formed by one end of the first baffle 121 and / or the second baffle 122 abutting against the outer frame 110, and the inclination angle of the second baffle 122 relative to the air inlet 211 and / or the air outlet 212 is greater than or equal to 0° and less than or equal to 180°, and the first sound absorbing portion 130 covers the baffle portion 120. The gas can flow in the main air duct 210, Fig.15 The direction of the middle arrow is the gas flow direction under one embodiment. In other embodiments, the gas flow direction may be opposite or other flow directions may be selected, which is not limited in this application. The main air duct 210 includes an air inlet 211, an air outlet 212 and a heat dissipation module 213 for heat dissipation. The heat dissipation module 213 is located between the air inlet 211 and the air outlet 212. In the embodiment of the utility model, the heat dissipation module 213 includes a fan module 2131 and a reactor 2132. The air inlet 211 and the air outlet 212 are respectively arranged on opposite sides of the main air duct 210 and staggered up and down. The sound-absorbing structure 100 is connected to the air inlet 211 and / or the air outlet 212.

[0061] The technical solution of the utility model is to set a sound-absorbing structure 100 at the air inlet 211 and / or the air outlet 212 of the main air duct 210. The sound-absorbing structure 100 includes a baffle 120 and a first sound-absorbing part 130. The first sound-absorbing part 130 covers the baffle 120, and can reduce the noise at the air inlet 211 and / or the air outlet 212. The inclination angle of the second baffle 122 relative to the air inlet 211 and / or the air outlet 212 is greater than or equal to 0° and less than or equal to 180°, so that the cross-sectional areas of the multiple air duct openings formed by the second baffle 122 dividing the interior of the sound-absorbing structure 100 are different, which can increase the number of reflection superpositions of sound waves in the air inlet 211 and / or the air outlet 212, thereby increasing the sound-absorbing effect, which is beneficial to reduce the noise at the air inlet 211 and / or the air outlet 212. When the sound waves inside the main air duct 210 pass through the sound absorption structure 100, due to the resonance sound absorption effect and the resistive sound absorption effect of the first sound absorption part 130, the sound waves inside the main air duct 210 are severely attenuated, thereby greatly reducing the sound waves radiated to the outside, which is beneficial to increase the sound absorption effect and reduce the noise at the air inlet 211 and / or the air outlet 212.

[0062] like Fig.15 As shown, the muffler device 200 further includes: a rectifying structure 220. The rectifying structure 220 is arranged at the air inlet 211 and / or the air outlet 212. The rectifying structure 220 can rectify and reduce the noise of the gas and noise in the main air duct 210. The rectifying structure 220 includes a grille structure 221. The technical solution of the utility model is conducive to reducing the noise at the air inlet 211 and / or the air outlet 212 by setting the rectifying structure 220, which includes a grille structure 221 capable of rectifying and reducing the noise of the gas in the main air duct 210.

The first cover plate 222 includes a first through opening 2221 and a mounting hole 2222. The first cover plate 222 and the second cover plate 223 are detachably connected. The grid structure 221 is arranged between the first cover plate 222 and the second cover plate 223. The second cover plate 223 includes a second through opening 2231 and a stud 2232. The first cover plate 222 and the second cover plate 223 are detachably connected through the stud 2232 and the mounting hole 2222. Those skilled in the art can also replace the form of the connecting member and the specific installation method of the connecting member according to actual needs. The present application does not limit the form of the detachable connection of the first cover plate 222 and the second cover plate 223. In actual applications, only the first cover plate 222 with the grid structure 221 fixed thereto or only the second cover plate 223 with the grid structure 221 fixed thereto can be used as the rectifying structure 220.

The mounting plate 2151 includes a second connecting portion 2153. The first connecting portion 2142 and the second connecting portion 2153 can be movably connected so that the mounting plate 2151 can be detachably mounted on the inner wall of the first air duct 214. The sound absorbing member 2152 is arranged on the mounting plate 2151. The technical solution of the utility model can realize the modular design of the second sound absorbing portion 215 by detachably mounting the second sound absorbing portion 215 on the inner wall of the first air duct 214, which is convenient for installation during use and for disassembly during maintenance or repair of the first air duct 214.

[0070] The embodiment of the utility model further provides a light storage system, comprising a muffler device 200 according to any of the aforementioned embodiments of the utility model.

[0071] The sound-absorbing structure 100 includes: an outer frame 110, a baffle 120 and a first sound-absorbing part 130. The edge of the outer frame 110 is composed of an arc segment, a plurality of continuous straight line segments or an arc segment and a straight line segment. The baffle 120 includes a plurality of cavities, which are formed by abutting one end of the first baffle 121 and / or the second baffle 122 against the outer frame 110. The inclination angle of the second baffle 122 relative to the air inlet 211 and / or the air outlet 212 is greater than or equal to 0° and less than or equal to 180°. The first sound-absorbing part 130 covers the baffle 120. Gas can flow in the main air duct 210. The main air duct 210 includes an air inlet 211, an air outlet 212 and a heat dissipation module 213 for heat dissipation. The heat dissipation module 213 is located between the air inlet 211 and the air outlet 212. The sound-absorbing structure 100 is connected to the air inlet 211 and / or the air outlet 212.

[0072] The technical solution of the utility model adopts the method of setting a silencer device 200 inside the solar storage system, wherein a silencer structure 100 is set at the air inlet 211 and / or the air outlet 212 of the main air duct 210 in the silencer device 200, and the silencer structure 100 includes a baffle 120 and a first sound absorbing part 130, and the first sound absorbing part 130 covers the baffle 120, and can reduce the noise at the air inlet 211 and / or the air outlet 212. The inclination angle of the second baffle 122 relative to the air inlet 211 and / or the air outlet 212 is greater than or equal to 0° and less than or equal to 180°, so that the cross-sectional areas of the multiple air duct openings formed by the second baffle 122 dividing the interior of the silencer structure 100 are different, which can increase the number of reflection superpositions of sound waves in the air inlet 211 and / or the air outlet 212, thereby increasing the silencer effect, which is conducive to reducing the noise at the air inlet 211 and / or the air outlet 212. When the sound waves inside the main air duct 210 pass through the sound absorption structure 100, due to the resonance sound absorption effect and the resistive sound absorption effect of the first sound absorption part 130, the sound waves inside the main air duct 210 are severely attenuated, thereby greatly reducing the sound waves radiated to the outside, which is beneficial to increase the sound absorption effect and reduce the noise at the air inlet 211 and / or the air outlet 212.
