Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly sound barrier application technology, and more specifically, to an environmentally friendly sound barrier that is easy to install and disassemble. Background Technology

[0002] Environmental protection (referred to as environmental protection) arose because industrial development has led to severe environmental pollution problems, which first attracted the attention of industrialized countries. It utilizes national laws and regulations and public opinion to make the whole society pay attention to and deal with pollution problems. At present, with social development, sound barriers are receiving more and more widespread demand in the field of sound insulation and environmental protection.

[0003] An environmentally friendly sound barrier, such as the one disclosed in publication number CN212714617U, is designed for easy installation and disassembly. It includes a base, fixed columns, mounting plates, mounting bolts, connecting plates, reinforcing plates, movable plates, movable grooves, a fixed frame, the sound barrier body, fixing bolts, an electric push rod, a rotating shaft, a rotating cylinder, a limit ring, a roller, cleaning brushes, and a motor. This type of environmentally friendly sound barrier features a simple structure and novel design, facilitating the installation of multiple sound barrier bodies. It also allows for the disassembly and repair of partially damaged sound barrier bodies, improving efficiency. Furthermore, it ensures the overall stability of the device, meeting user needs and providing ease of operation. During use, the built-in cleaning mechanism automatically cleans the surface of the sound barrier body, reducing workload and improving cleaning effectiveness. This ensures a clean surface for the sound barrier and facilitates its use, indicating a broad market prospect.

[0004] However, based on the working principle proposed in the aforementioned patent, the applicant believes that although the above-mentioned device can improve the cleaning effect to a certain extent, in actual use, the existing sound barriers are not very flexible, are difficult to fold and disassemble for portability, and some sound barriers are made of poor materials with low sound absorption efficiency, which has certain defects in use. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides an environmentally friendly sound barrier that is easy to install and disassemble, and has the advantages of more flexible folding and disassembly and higher sound absorption efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly sound barrier that is easy to install and disassemble, comprising an upper frame, a lower frame movably installed at the bottom of the upper frame, the upper frame and the lower frame being connected by a first hinge, a second hinge fixedly installed at the top of the upper frame, a top rod movably connected to the top of the second hinge, connecting shafts movably installed on both sides of the lower frame, side columns fixedly connected to the outer side of the connecting shafts, and the top rod fixedly installed on the top of the side columns.

[0007] As a preferred technical solution of this utility model, a sound shield is fixedly installed on the inner side of both the upper frame and the lower frame, and the outer surface of the sound shield is made of porous ceramic fiber board.

[0008] As a preferred embodiment of this utility model, the inner side of the porous ceramic fiber board is provided with a recycled cotton layer from waste textiles, and the inner side of the recycled cotton layer from waste textiles is provided with a biodegradable plant fiber layer.

[0009] As a preferred embodiment of this utility model, a connecting protrusion is fixedly installed on one side of the side column, and a connecting groove is provided on the other side of the side column.

[0010] As a preferred embodiment of this utility model, a bottom connecting plate is fixedly installed at the bottom of the side column, and the bottom connecting plate is in direct contact with the ground.

[0011] As a preferred embodiment of this utility model, a tapered rod is fixedly installed at the middle position of the bottom surface of the bottom connecting plate, and a fixing hole is opened on the surface of the bottom connecting plate and on the outer side of the tapered rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model significantly improves flexibility and portability through the coordinated design of the foldable connecting structure and the bottom connecting plate. The modular splicing method of connecting protrusions and connecting grooves, together with the cone rod and fixing holes at the bottom of the bottom connecting plate, enables quick installation and stable fixation. Disassembly can be completed by simply reversing the operation. The upper frame and lower frame are folded by the first hinge, combined with the linkage support of the top rod and side column, so that the sound shield can be folded into a compact form, which is convenient for transportation and reuse.

[0014] 2. This utility model further optimizes sound absorption efficiency through multi-layer composite materials. The outer porous ceramic fiber board disperses sound wave energy through pores, the middle layer of recycled cotton from waste textiles consumes mid-to-high frequency noise through fiber friction, and the inner biodegradable plant fiber layer blocks the transmission of residual low-frequency sound waves. At the same time, the rigid connection design between the shaft and the side column enhances the overall structural stability and avoids the decline in sound absorption performance due to vibration. The inclined guide surface of the top rod can also reduce the erosion of the material by rainwater accumulation and extend the service life. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6 As shown, this utility model provides an environmentally friendly sound barrier that is easy to install and disassemble, including an upper frame 1, a lower frame 2 movably installed at the bottom of the upper frame 1, the upper frame 1 and the lower frame 2 being connected by a first hinge 3, a second hinge 4 fixedly installed at the top of the upper frame 1, a top rod 5 movably connected to the top of the second hinge 4, connecting shafts 6 movably installed on both sides of the lower frame 2, side posts 7 fixedly connected to the outer side of the connecting shafts 6, and the top rod 5 fixedly installed on the top of the side posts 7.

[0024] The upper frame 1 and the lower frame 2 are both fixedly installed with sound shielding panels 8, and the outer surface of the sound shielding panels 8 is made of porous ceramic fiber board 9.

[0025] The sound shield panel 8 integrates sound absorption and sound insulation functions, improving noise reduction performance. The porous ceramic fiber panel 9 disperses sound wave energy and adsorbs particulate matter, thus combining noise reduction and environmental protection.

[0026] The porous ceramic fiber board 9 has a recycled cotton layer 10 made from waste textiles on its inner side, and a biodegradable plant fiber layer 11 made from the recycled cotton layer 10 on its inner side.

[0027] By setting up the recycled cotton layer 10 from waste textiles, medium and high frequency noise can be absorbed efficiently, realizing the resource utilization of waste. By setting up the biodegradable plant fiber layer 11, low frequency noise transmission can be blocked, while reducing material environmental pollution.

[0028] A connecting protrusion 12 is fixedly installed on one side of the side column 7, and a connecting groove 13 is provided on the other side of the side column 7.

[0029] By setting the connecting protrusion 12, the adjacent side posts 7 can be quickly plugged in, simplifying the splicing process. By setting the connecting groove 13, the connecting protrusion 12 can be matched to ensure the accuracy and stability of modular splicing.

[0030] Among them, the bottom of the side column 7 is fixedly installed with a bottom connecting plate 14, which is in direct contact with the ground.

[0031] By setting the bottom connecting plate 14, the contact area between the side column 7 and the ground can be increased, thereby improving the overall anti-overturning ability.

[0032] A tapered rod 15 is fixedly installed at the middle position of the bottom surface of the bottom connecting plate 14, and a fixing hole 16 is opened on the surface of the bottom connecting plate 14 and on the outside of the tapered rod 15.

[0033] The cone rod 15 can be inserted into the ground to achieve pre-positioning and prevent slippage during installation. The fixing hole 16 can be used with ground nails or bolts for secondary reinforcement to ensure long-term stability.

[0034] The working principle and usage process of this utility model are as follows: When using this device, the upper frame 1 and lower frame 2 are folded and stored through the first hinge 3 to reduce the volume during transportation. When installed, after unfolding, the side column 7 is rotated to a vertical state through the connecting shaft 6. The top rod 5 is adjusted at the angle through the second hinge 4 and fixed to the top of the side column 7 to form a stable triangular support structure. The sound shield 8 disperses sound wave energy and absorbs dust through the outer porous ceramic fiber board 9. The middle layer of recycled cotton from waste textiles 10 absorbs mid-to-high frequency noise through fiber friction. The inner layer of biodegradable plant fiber 11 blocks the transmission of residual low-frequency sound waves. The bottom connecting plate 14 at the bottom of the side column 7 is inserted into the ground for pre-positioning through the cone rod 15 and reinforced by driving in ground nails with the fixing hole 16. At the same time, the connecting protrusions 12 on both sides of the side column 7 are quickly inserted into the connecting grooves 13 of the adjacent modules to achieve seamless splicing of multiple units, taking into account efficient noise reduction, quick disassembly and assembly, and environmental recycling.
