Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a sound insulation mechanism based on photovoltaic power generation sound-proof screen, includes

base plate

1, 1 upper end fixed bonding of base plate has slotted wood abatvoix 6, open slot wood abatvoix 6 up end has first sound absorbing hole 63, open slot wood abatvoix 6 bottom face has second sound absorbing hole 64, the vertical intercommunication in first sound absorbing hole 63 bottom and second sound absorbing hole 64 top, and the aperture of first sound absorbing hole 63 is greater than the aperture of second sound absorbing hole 64, first sound absorbing hole 63 and second sound absorbing hole 64 all set up a plurality of, and even range is on slot wood abatvoix 6, and when sound was inhaled, it is partly absorbed after first sound absorbing hole 63 enlargies, becomes heat energy, is absorbed after second sound absorbing hole 64 again, and the sound reflection is minimum, produces good sound absorbing effect, the propagation of reduction sound that can to a great extent. The top end of the groove wood sound-absorbing board 6 is fixedly bonded with a pressing board 61, the pressing board 61 is provided with transverse grooves 62, the number of the transverse grooves 62 is not less than three, the transverse grooves 62 are arranged on the pressing board 61 in parallel at equal intervals, the bottom ends of the transverse grooves 62 are communicated with the top ends of the first sound-absorbing holes 63, and sound is absorbed into the first sound-absorbing holes 63 from the transverse grooves 62. The inner cavity of the transverse groove 62 is embedded with a sound absorption cotton sliver 5 which is artificial inorganic fiber. The glass is prepared by using natural ores such as quartz sand, limestone, dolomite and the like as main raw materials and matching with chemical raw materials such as sodium carbonate, borax and the like. Under melting the state, with the help of external force blowing type get rid of into flocculent thin fiber, be the intercrossing between fibre and the fibre, the intertwine is in the same place, demonstrates many tiny clearances, has characteristics such as the sound absorption rate is high, sound-proof quality is good, the heat-proof quality is good, fire resistance is good, can tentatively inhale the sound, reaches the syllable-dividing effect, clamp plate 61 upper end is fixed to bond has wooden syllable-dividing
