DETAILED DESCRIPTION

[0035] It should be noted that the following detailed description is exemplary and is intended to further explain the present application. Unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs.

[0036] The present application will be described in detail below with reference to the accompanying drawings. The movable modular soundproof screen disclosed in the present embodiment is a U-shaped structure composed of multiple sound barrier units, which encloses the construction equipment therein. Figure 1 As shown in the figure, the sound barrier unit includes a sound barrier body 2, and the two sides of the sound barrier body 2 are respectively fixedly connected to a bottom support 5. Figure 2 The bottom support 5 is usually designed as a rectangle, and a universal wheel 7 is fixedly connected to the center of the bottom surface of the bottom support 5. The two universal wheels 7 provided on the bottom can move the sound barrier unit.

[0037] As shown in the figure, Figure 2 , Figure 3 The sound barrier body 2 is fixedly connected to the centerline of the bottom support 5, and the adjusting support 6 is provided on the bottom support 5 on both sides of the sound barrier body 2. The adjusting support 6 includes an adjusting bolt 61, and the bottom end of the adjusting bolt 61 is fixedly connected to an adjusting base 62. It can be understood that adjusting screw holes are provided on the bottom support 5 on both sides of the sound barrier body 2, and the adjusting bolt 61 is connected to the bottom support 5 in a threaded connection manner, and the adjusting base 62 needs to be below the bottom surface of the bottom support 5 when the adjusting bolt 61 is connected to the bottom support 5. When the construction site is not level, the multiple adjusting bolts 61 at the bottom of the sound barrier body 2 are adjusted so that the multiple adjusting bases 62 contact the ground, which can level the bottom support of the sound barrier body 2 and form an effective support. When the sound barrier unit is connected to the sound barrier unit, it is convenient to connect and not easy to shake after connection; and the height of the sound barrier body 2 relative to the ground can also be adjusted by the adjusting support 6, so that the heights of all sound barrier bodies 2 are consistent, which is more convenient for connection.

[0038] It should be noted that in the non-working state, the adjusting base 62 on the sound barrier body 2 is attached to the bottom surface of the bottom support 5, so as to avoid the adjusting base 62 from hindering the movement of the sound barrier monomer.

[0039] As shown in Figure 2 , the sound barrier body 2 comprises a fixedly connected upper screen body 21 and a lower screen body 22, and an included angle exists between the upper screen body 21 and the lower screen body 22. The included angle is an obtuse angle, and the included angle surface needs to be directed to the construction side to block the construction noise as much as possible. Figure 2 As shown in , a lifting ring 3 is fixedly arranged at the top center of the sound barrier body 2, i.e. the top center of the upper screen body, so as to facilitate hoisting during loading, transportation or installation.

[0040] Figure 2 As shown in Figure 2 , Figure 4 , a third ear plate 23 is arranged on the lower screen body 22, and the lower screen body 22 is hinged to the inclined support structure 1 through the third ear plate. In this embodiment, the third ear plate 23 is fixedly arranged at the intersection of the bottom edge middle line and two-thirds of the height of the lower screen body 22. The arrangement at this position can enable the inclined support structure 1 to best support the lower screen body 22.

[0041] As shown in Figure 5 , Figure 6 , the inclined support structure 1 comprises a telescopic inclined support rod 11, one end of which is hinged to the lower screen body 22, and the other end is hinged to an inclined support support 12. The telescopic inclined support rod 11 is composed of a telescopic rod 13 and a telescopic sleeve rod 14. The telescopic rod 13 is sleeved inside the telescopic sleeve rod 14, and the telescopic sleeve rod 14 is provided with opposite telescopic screw holes 15 on the rod body for threadedly connecting telescopic locking bolts. The telescopic rod 13 can slide relative to the telescopic sleeve rod 14, so that the telescopic inclined support rod 11 can be lengthened and shortened. After the length of the telescopic inclined support rod 11 is adjusted, the telescopic locking bolts are threadedly connected in the telescopic screw holes 15, so that the telescopic locking bolts on both sides of the telescopic sleeve rod 14 tightly press the telescopic rod 13, thereby limiting the movement of the telescopic rod 13.

[0042] As shown in Figure 5 , Figure 6 , the end of the telescopic sleeve rod 14 away from the telescopic rod 13 is provided with a first ear plate 16, and the end of the telescopic rod 13 away from the telescopic sleeve rod 14 is provided with a second ear plate 17; and the top surface of the inclined support support 12 is fixedly provided with a fourth ear plate 18. The first ear plate and the third ear plate are aligned and inserted into a pin shaft to complete the hinge connection; similarly, the second ear plate and the fourth ear plate are aligned and inserted into a pin shaft to complete the hinge connection.

[0043] As shown in Figure 2As shown, since multiple sound barrier monomers form a U shape, each side supports each other, which can prevent the sound barrier monomer from overturning towards the construction surface when the wind blows. However, when the wind blows from the construction surface outward, each side cannot form an effective pulling force, and there is an included angle between the upper screen body 21 and the lower screen body 22, which can converge and increase the wind power. Therefore, the inclined support structure 1 can prevent the sound barrier monomer from having the risk of overturning.

[0044] It can be understood that by adjusting the length of the telescopic inclined support rod 11 and the angle between the telescopic inclined support rod 11 and the lower screen body 22, the inclined support structure 1 can form the most effective support for the sound barrier monomer. The articulation between the inclined support bracket 12 and the telescopic inclined support rod 11 can also ensure that the inclined support bracket 12 is attached to the ground to form effective support.

[0045] In some embodiments, a plurality of fixing holes are provided on the inclined support bracket 12. By providing a fixing member in the fixing hole and fixing the fixing member to the ground, the inclined support bracket is fixed to the ground. When the ground is a soil layer, the fixing member here can be a short steel bar; when the ground is a concrete structure, the fixing member here can be an expansion bolt, which is selected according to the actual situation.

[0046] As shown in Figure 7 , the lower screen body 22 includes an internally hollow metal frame plate 8, one side of the metal frame plate 8 is provided with a sound penetrating hole; the inside of the metal frame plate 8 is provided with a layer of sound absorbing plate 9 and a layer of sound insulation plate 10, wherein the sound absorbing plate 9 is arranged on the side of the sound penetrating hole. In this embodiment, the sound absorbing plate is made of glass fiber cotton material, and the sound insulation plate is made of polyester fiber sound insulation felt.

[0047] It can be understood that the structure of the upper screen body 21 is the same as that of the lower screen body; the above-mentioned lifting eye or third ear plate is fixed to the surface of the metal frame plate 8 of the upper screen body or the lower screen body; the sound penetrating hole is arranged on the plane where the included angle is located.

[0048] As shown in Figure 8 , adjacent sound barrier monomers are connected through the hinge 4. Specifically, after the adjacent sound barrier monomers are leveled at the bottom, the inclined support structure is supported in place, and the heights of the adjacent sound barrier monomers are consistent, the adjacent sound barrier monomers are installed by installing the hinge 4. Two groups of hinge installation holes can be drilled on both sides of the plane where the inclined support structure 1 is located on the lower screen body 22 of each sound barrier monomer. The hinge installation hole positions of each sound barrier monomer are the same, which facilitates the connection between the sound barrier monomers.

[0049] It can be understood that when disassembling, the hinge 4 is disassembled first, then the inclined support structure 1 of each sound barrier monomer is disassembled, and finally the base 62 is adjusted to support the sound barrier monomer by the universal wheel.

[0050] The soundproof screen of the embodiment is provided with multiple adjusting supports at the bottom of the sound barrier body, when the construction site is uneven, the multiple adjusting supports are contacted with the ground by adjusting the adjusting bolts, which can adjust the bottom supports of the sound barrier body, form effective supports, and make the sound barrier body not easy to shake after being connected; and the height of the sound barrier body relative to the ground can be adjusted through the adjusting supports, so that the heights of all the sound barrier bodies are consistent, and finally the connection between the sound barrier bodies is facilitated. The diagonal brace structure is hinged on the sound barrier body, the diagonal brace structure is firmly connected with the ground through the diagonal brace supports; the diagonal brace structure can effectively support the sound barrier body by adjusting the length of the telescopic diagonal brace rod, the angle between the telescopic diagonal brace rod and the lower screen body, and the angle between the telescopic diagonal brace rod and the diagonal brace support, so as to prevent the sound barrier body from being blown down by the wind from the construction direction.

[0051] Although the specific embodiments of the utility model have been described above with reference to the drawings, it is not a limitation on the protection scope of the utility model, and those skilled in the art should understand that various modifications or changes made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
