DETAILED DESCRIPTION

[0025] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by terms such as “upper”, “lower”, “left”, “right”, “front”, “back”, “top” and “bottom” are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0027] like Figure 1 to Figure 7As shown, a photovoltaic sound barrier device of a preferred embodiment of the present invention includes a sound barrier body 1 and a movable photovoltaic panel 2, wherein the sound barrier body 1 is formed by assembling a plurality of sound barrier units, wherein the sound barrier unit includes a photovoltaic panel 11, a sound absorbing material layer 12, a sound insulation backboard 13 and a frame 14, wherein the photovoltaic panel 11 includes a photovoltaic glass 114 and a photovoltaic cell 111, wherein the photovoltaic cell 111 is sandwiched between two photovoltaic glasses 114, wherein a packaging material 113 is filled between the photovoltaic cell 111 and the photovoltaic glass 114, wherein the photovoltaic glass 114 is evenly provided with through holes 112 except for the area where the photovoltaic cell 111 is provided, and sound waves enter the sound barrier through the through holes 112 The sound absorbing material layer 12 inside the unit reduces noise by the sound absorbing material. The sound absorbing material layer 12 is covered on one side of the frame 14. The photovoltaic panel 11 is covered on the sound absorbing material layer 12. The photovoltaic panel 11 faces the road or the railway. The sound insulation backboard 13 is covered on the other side of the frame 14. The sound absorbing material layer 12 and the sound insulation backboard 13 are sandwiched between the frame 14 to form a sound absorbing cavity 141. The movable photovoltaic panel 2 includes a photovoltaic module 21 and an adjustment drive mechanism. The photovoltaic module 21 is close to the sound insulation backboard 13 and is provided with a flexible sealing material layer 26 on the sides thereof. When the photovoltaic module 21 is close to the sound insulation backboard 13, the sound barrier can be reduced. The vibration of the unit panel sound insulation back plate 13 improves the noise reduction effect of the overall structure of the sound photovoltaic sound barrier device, making it easier to meet the noise emission standards at night; each group of the adjustment drive mechanism includes a first telescopic rod 22 and a second telescopic assembly 23, and multiple groups of the second telescopic assemblies 23 are arranged in a rectangular shape and surround the outer periphery of the first telescopic rod 22. Multiple groups of the second telescopic assemblies 23 form a matrix arrangement with the first telescopic rod 22, and each of the second telescopic assemblies 23 includes a second telescopic rod 24 and a telescopic connecting rod 25. The frame 14 is provided with a first mounting groove 142 and a plurality of second mounting grooves 143. One end of the first telescopic rod 22 is connected to the bottom of the first mounting groove 142. The first telescopic rod 2 The other end of the first telescopic rod 22 is rotatably connected to the photovoltaic assembly 21, the second mounting groove 143 and the second telescopic assembly 23 are arranged in a one-to-one correspondence, one end of the second telescopic rod 24 is connected to the bottom of the second mounting groove 143, the other end of the second telescopic rod 24 is rotatably connected to one end of the telescopic connecting rod 25, and the other end of the telescopic connecting rod 25 is rotatably connected to the photovoltaic assembly 21. As the position of the sun changes continuously, by adjusting the extension lengths of the first telescopic rod 22 and each of the second telescopic rods 24 and the telescopic connecting rod 25, the angle of the photovoltaic assembly 21 can be arbitrarily adjusted, so that the photovoltaic assembly 21 in the photovoltaic sound barrier device can always face the sun, so that the power generation of the photovoltaic assembly 21 is maximized;When the adjustment drive mechanism is retracted, the first telescopic rod 22 is completely accommodated in the first mounting groove 142, the second telescopic assembly 23 is completely accommodated in the second mounting groove 143, the photovoltaic assembly 21 is tightly attached to the sound insulation back plate 13, and the two adjacent active photovoltaic panels 2 are tightly fitted. Furthermore, the active photovoltaic panel 2 is staggered with the sound barrier unit, and the active photovoltaic panel 2 is covered on the joint between the two adjacent sound barrier units, effectively covering the joint between the two sound barrier units where noise leakage is prone to occur, reducing the design margin of the sound barrier body 1, using less sound absorbing material to achieve the best sound absorption and noise reduction effect, and reducing the cost of the sound barrier body 1; in this way, part of the second telescopic assembly 23 in the active photovoltaic panel 2 is connected to the frame 14 of one sound barrier unit, and the rest of the second telescopic assembly 23 in the active photovoltaic panel 2 is connected to the frame 14 of another adjacent sound barrier unit. Wherein, the photovoltaic sound barrier device may be a semi-enclosed photovoltaic sound barrier device or a fully enclosed photovoltaic sound barrier device, the upright section of the semi-enclosed photovoltaic sound barrier device or the fully enclosed photovoltaic sound barrier device is installed in an upright manner, and the top of the fully enclosed photovoltaic sound barrier device is installed in a horizontal manner. ;

When the detected wind speed is greater than a preset value, the adjusting drive mechanism retracts the photovoltaic assembly 21, effectively protecting the photovoltaic assembly 21 and the adjusting drive mechanism, and improving the safety of use and structural stability. When the wind speed is too high, if the adjusting drive mechanism extends the photovoltaic assembly 21, it is easy to cause the first telescopic rod 22, the second telescopic assembly 23 and the telescopic connecting rod 25 to deform, resulting in the photovoltaic assembly 21 being unable to fit tightly against the sound barrier body 1, affecting the sound insulation effect; by timely retracting the photovoltaic assembly 21, the service life of the movable photovoltaic panel 2 can be effectively extended.

[0029] The photovoltaic panel 11 of the present invention is provided with a through hole 112 to enable sound to quickly enter the interior of the sound barrier unit, so that the sound is absorbed and consumed by the sound absorbing material layer 12, so that the noise is attenuated, and the sound absorption effect of the sound absorbing cavity 141 is cooperated to achieve the purpose of noise reduction, and the sound insulation back plate 13 can enhance the sound insulation effect. At the same time, when the movable photovoltaic panel 2 is closed, the photovoltaic component 21 can be tightly covered on the sound barrier body 1, thereby improving the sound insulation performance of the sound barrier unit board, reducing the design margin of the sound barrier body 1, using less sound absorbing material to achieve a better noise reduction effect, and reducing the cost of the sound barrier body 1; Moreover, the photovoltaic panel 11 can also play the function of photovoltaic power generation and improve space utilization. The first telescopic rod 22, the second telescopic rod 24 and the telescopic connecting rod 25 cooperate to effectively improve the supporting effect of the adjustment drive mechanism on the photovoltaic component 21, and can effectively, quickly and simply adjust the angle of the photovoltaic component 21 according to the angle of sunlight, change the inclination and azimuth of the photovoltaic component 21 and the sun, increase the illumination time and illumination area of ​​the photovoltaic component 21, and make the photovoltaic component 21 always in the maximum power generation state, thereby improving the power generation efficiency. The present invention can effectively improve the noise reduction effect of sound absorption and sound insulation, and at the same time improve the power generation efficiency.

[0031] Exemplarily, a sealing strip 144144 is provided at the joint between two adjacent sound barrier units, which can reduce the sound leakage defect at the joint between the adjacent sound barrier units.

[0032] In this embodiment, if Figure 6 As shown, the two opposite edges of the sound barrier unit are respectively provided with a protrusion 15 and a groove 16 that can be interlocked with each other, and the protrusion 15 and the groove 16 cooperate to form a bending structure, thereby reducing the leakage of noise from the joints between adjacent sound barrier units and improving the noise reduction effect of the entire photovoltaic sound barrier device. In another embodiment, as Figure 7 As shown, the two opposite edges of the sound barrier unit are respectively provided with Z-shaped grooves 17 that can be engaged with each other.

[0033] Exemplarily, soundproof glass is provided on both sides of the photovoltaic assembly 21, and the thickness of the soundproof glass is 3 mm to 4 mm. When the movable photovoltaic panel 2 is in a closed state, the sound insulation of the sound barrier body is improved.

[0034] In this embodiment, the sound insulation back plate 13 is a metal plate. The noise enters the sound barrier unit through the via 112 on the photovoltaic panel 11. The noise energy is attenuated to a certain extent through the absorption and consumption of the sound absorbing material layer 12 and the sound absorbing cavity 141. Then, the noise is controlled by the sound insulation performance of the sound insulation back plate 13, and finally the sound pressure level of the noise passing through the sound barrier unit is reduced to achieve the purpose of noise reduction.

[0035] like Figure 8 As shown, in the present embodiment, the second telescopic components 23 are provided with eight groups and are respectively connected to the four peripheries of the photovoltaic component 21, the second telescopic components 23 include a second telescopic component I 231, a second telescopic component II 232, a second telescopic component III 233, a second telescopic component IV 234, a second telescopic component V 235, a second telescopic component VI 236, a second telescopic component VII 237 and a second telescopic component VIII 238, that is, the second mounting grooves 143 are correspondingly provided with eight, and the first telescopic rod 22 is connected to the center of the photovoltaic component 21.
