DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 A noise prevention and control device for environmental protection engineering comprises a vertical rod 2 and a bottom seat 1. There are two groups of vertical rods 2. A vertical groove 21 is provided at the top of the vertical rod 2 along the vertical direction. Multiple groups of noise reduction plates 3 are movably inserted between the two groups of vertical rods 2. An edge seat 13 is fixedly provided on the side of the bottom of the vertical rod 2. A vertical groove 10 is provided on the side of the edge seat 13. The top of the vertical groove 10 is fixedly connected to one end of a connecting spring 9. The other end of the connecting spring 9 is fixedly connected to the side of a vertical moving block 11. A horizontal shaft 12 is fixedly provided on the side of the vertical moving block 11. A protective component for protecting the multiple groups of noise reduction plates 3 is provided on the outer wall of the horizontal shaft 12.

[0021] The protection component includes a vertical column 5, a protection column 6, and a horizontal plate 8. The bottom of the vertical column 5 is rotatably connected to the outer wall of the horizontal axis 12. The protection columns 6 are equidistantly fixed between the two groups of vertical columns 5. The protection columns 6 are made of steel. When the protection component is in a vertical state, there is a gap between the protection component and the multiple groups of noise reduction plates 3. When an accidental collision of vehicles occurs, the protection component can replace the multiple groups of noise reduction plates 3 to be hit.

[0022] A horizontal plate 8 is fixedly installed on the top of the two groups of vertical columns 5. The cross-sectional area of ​​the horizontal plate 8 when viewed from above is not smaller than the cross-sectional area of ​​the noise reduction plate 3 when viewed from above. Therefore, when the horizontal plate 8 is at the top of the two groups of vertical rods 2, multiple groups of noise reduction plates 3 can be limited between the two groups of vertical rods 2.

[0023] A lifting handle 4 is fixedly provided on the side of the vertical column 5, a limiting column 7 is symmetrically fixedly provided on the bottom of the horizontal plate 8, a positioning hole 22 is opened on the top of the vertical rod 2 on one side of the vertical groove 21, and the limiting column 7 has the same diameter as the positioning hole 22. A bottom connecting seat 1 is fixedly provided at the bottom of the two groups of vertical rods 2, and mounting holes are opened at the four corners of the top of the bottom connecting seat 1, and the entire equipment can be fixed on the road surface by expansion bolts.

[0024] The specific implementation steps and principles of the utility model are as follows:

[0025] When the entire protective assembly is in a vertical state to protect the side surfaces of multiple groups of noise reduction plates 3, the connecting spring 9 is in its original length, the limiting column 7 is inserted into the positioning hole 22, and the horizontal plate 8 closes the top of the two groups of vertical rods 2. When it is necessary to scrub the side surfaces of the noise reduction plates 3 or replace the noise reduction plates 3, the lifting handle 4 is pushed up by manpower, and the lifting handle 4 drives the vertical column 5 to move upward. At this time, the limiting column 7 is disengaged from the positioning hole 22, and the entire protective assembly can be rotated around the edge seat 13 to expose the side surfaces of multiple groups of noise reduction plates 3.

[0026] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
