Description
Technical Field
[0001] The utility model relates to the technical field of road noise reduction equipment, in particular to a noise prevention and control sound barrier. Background Art
[0002] In environmental protection projects, noise control sound barriers are facilities used to reduce noise propagation. They are usually composed of sound insulation materials and mechanical structures. They are mainly used to limit the spread of noise in industrial areas, roadsides and urban environments to reduce interference and harm to surrounding residents and the environment. Due to environmental factors and long-term use, dust and debris will accumulate on the surface of the sound barrier, affecting its sound insulation effect. The transparent acrylic plate on the sound barrier needs to be cleaned regularly. Some existing highways are located on viaducts, and the sound barriers on them are located on both sides of the viaduct. There are few places outside the viaduct for people to stand. When the staff cleans the sound barrier, they can often only clean the inside of the sound barrier. The outside of the sound barrier is located outside the viaduct, and it is generally not possible to clean the outside of the sound barrier well. For this reason, we propose a noise control sound barrier. Utility Model Content
[0003] A technical problem to be solved by this application is: how to design a structure that allows workers to clean the outside while standing inside the sound barrier.
[0004] In order to solve the above technical problems, the embodiment of the present application provides a noise prevention sound barrier, including two vertical plates of the sound barrier, transparent plates are installed on the vertical plates, and also includes:

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Example 1
[0028] See also Figure 1-7 The utility model provides a technical solution: a noise prevention sound barrier, comprising two vertical plates 1 of the sound barrier, a transparent plate 2 is installed on the vertical plate 1, and also includes:
[0029] A deflection rod 3, the deflection rod 3 is located between the two vertical plates 1, and the deflection rod 3 is rotatably connected to the vertical plates 1;
[0030] A sponge bar 4 is slidably disposed on the vertical plate 1 and is located outside the transparent plate 2. The sponge bar 4 is cylindrical and is used to clean the transparent plate 2.
[0031] The linkage component 5 is arranged on the deflection rod 3. The staff stands on the inner side of the sound barrier and deflects the deflection rod 3. The sponge strip 4 is driven to slide and clean the outer side of the transparent plate 2 through the linkage component 5. Specifically, the linkage component 5 includes an axis 1 51 fixedly arranged on the deflection rod 3. The axis 1 51 is rotatably connected to the vertical plate 1. A limiting groove 52 is provided on the vertical plate 1. An axis 2 53 is fixedly installed on the sponge strip 4. The axis 2 53 is slidably connected to the vertical plate 1. The axis 2 53 is located in the limiting groove 52. A groove 1 54 is provided on the deflection rod 3. A movable rod 55 is rotatably connected to the axis 2 53. One end of the movable rod 55 is located in the groove 1 54 and slides;
[0032] Pulling the handle 8 drives the deflection rod 3 to deflect and tilt through the axis 1 51, thereby driving the movable rod 55 to deflect and tilt, thereby driving the axis 2 53 to slide in the limiting groove 52, and the movable rod 55 to slide in the groove 1 54, thereby driving the sponge bar 4 to slide, so that the sponge bar 4 cleans and scrapes the dust on the transparent plate 2.
[0033] A protective cover 6 is placed outside the sponge bar 4 to protect the sponge bar 4. A shaft three 61 is fixedly connected to the protective cover 6. The shaft three 61 is rotatably connected to the vertical plate 1. A torsion spring 1 62 is sleeved on the shaft three 61. The two ends of the torsion spring 1 62 are respectively fixedly connected to the shaft three 61 and the vertical plate 1. A guide block 63 is fixedly arranged inside the protective cover 6. The inclined surface of the guide block 63 contacts the sponge bar 4. A guide block 63 is also arranged outside the protective cover 6. When the sponge bar 4 slides, it contacts the guide block 63 and presses against the guide block 63. The protective cover 6 will slowly deflect along the guide block 63, and then the sponge bar 4 can be separated from the protective cover 6. If the sponge bar 4 wants to enter the protective cover 6, the sponge bar 4 still presses against the guide block 63 outside the protective cover 6. The sponge bar 4 presses against the guide block 63, forcing the protective cover 6 to deflect, so that the sponge bar 4 can slide into the protective cover 6, and the protective cover 6 is automatically reset under the action of the torsion spring 1 62.
[0034] A torsion spring 2 7 is sleeved on the shaft 1 51, and the two ends of the torsion spring 2 7 are fixedly connected to the shaft 1 51 and the vertical plate 1 respectively. After the deflection rod 3 drives the sponge strip 4 to clean, once you let go, the deflection rod 3 can automatically reset under the action of the torsion spring 2 7, and the transparent plate 2 can be cleaned again during the resetting process.
[0035] A handle 8 is provided at one end of the deflection rod 3, and a shaft 4 81 is fixedly connected to the handle 8. The shaft 4 81 slides in the deflection rod 3. A groove 2 82 is opened on the vertical plate 1, and the handle 8 slides in the groove 2 82. A spring 83 is sleeved on the shaft 4 81, and the two ends of the spring 83 are respectively in contact with the handle 8 and the deflection rod 3. The handle 8 is slid to drive the shaft 4 81 to slide, and the shaft 4 81 slides out of the groove 2 82. At this time, the deflection rod 3 is unlocked. The handle 8 is slid to drive the shaft 4 81 to slide, so that the shaft 4 81 slides into the groove 2 82. At this time, the deflection rod 3 is fixed. Under the action of the spring 83, the handle 8 is always pressed against and located in the groove 2 82, so as to effectively fix it.
[0036] A sponge strip 4 is also provided on the other side of the deflection rod 3. The sponge strips 4 on both sides are centered on the deflection rod 3 and adopt a centrally symmetrical design. In this way, by deflecting the deflection rod 3 once, the sponge strips 4 on both sides can be driven to clean the transparent plates 2 on both sides at the same time, saving time and effort and improving the work efficiency of workers.
[0037] Example 2
[0038] See also Figure 1-9 The utility model provides a technical solution: a noise prevention and control sound barrier. Embodiment 2 is optimized based on embodiment 1.
[0039] A rack 9 is fixedly installed in the limiting groove 52, and a toothed disc 10 is fixedly connected to the second shaft 53. The toothed disc 10 and the rack 9 are meshed with each other. When the second shaft 53 slides along the limiting groove 52, the rack 9 remains stationary, and the toothed disc 10 meshing therewith starts to rotate, thereby driving the second shaft 53 to rotate, thereby driving the sponge bar 4 to rotate, and the direction of rotation of the sponge bar 4 is opposite to the direction of rotation when the sponge bar 4 slides naturally. This can increase the cleaning effect and further clean the dust.
