[0031] The working principle of the embodiment of the present invention is: the lifting assembly is responsible for adjusting the height of the sound insulation main board 1 to adapt to the needs of different construction environments. The second servo motor 15 is started in the protective shell 13 to drive the second bidirectional screw 16 to rotate. Since the second bidirectional screw 16 is threadedly connected to the adjustment block 17, the rotation of the second bidirectional screw 16 is converted into a linear motion of the adjustment block 17.

[0034] The working principle of the embodiment of the present invention is as follows: the adjustment component is used to adjust the coverage of the sound insulation main board 1 to adapt to the noise sources in different construction areas. The double-axis motor 22 in the fixed seat 21 on the top right side is started, and one of its output shafts drives the third bidirectional screw 23 to rotate through the coupling, so that the first moving block 24 moves along the direction of the third bidirectional screw 23. At the same time, the other output shaft of the double-axis motor 22 drives the rotating rod and the first rotating roller 28 to rotate, and drives the fourth bidirectional screw 25 and the second rotating roller 29 to rotate synchronously through the belt transmission, thereby driving the second moving block 26 to move, so that the first moving block 24 and the second moving block 26 respectively drive the sound insulation sub-plate 27 thereon to extend or contract to both sides, thereby adjusting the sound insulation range. In addition, the connection component between the bottom fixed seat 21 realizes the synchronous adjustment of the sound insulation sub-plates 27 on both sides through the rotation of the fourth bidirectional screw 25, ensuring the balance and accuracy of the adjustment.

[0035] By designing the sliding wheel 30 at the bottom of the movable base plate 12, the entire device can be flexibly moved at the construction site, and the position can be adjusted according to construction needs.
