Abstract
Description
Technical Field
[0001] This utility model relates to the field of fencing technology, and in particular to a hollow, one-time injection-molded composite fencing. Background Technology
[0002] A construction site fence is a temporary or semi-permanent barrier structure used for isolation, protection, or demarcation of areas. It is usually made of metal, plastic, wood, concrete, or other composite materials and is widely used in construction sites, municipal engineering projects, traffic management, event venues, and other scenarios. Common types include color steel plate fences, PVC fences, water-filled barriers, and metal mesh fences.
[0003] Most construction site fences do not have sound absorption or noise reduction functions. Meanwhile, the operation of various mechanical equipment and the handling of materials at construction sites often generate a large amount of noise. Without effective barriers to block this noise, it spreads freely into the surrounding environment. Long-term exposure to such noise can seriously threaten the quality of life and mental and physical health of nearby residents, potentially leading to a series of health problems. Furthermore, when drivers are distracted by noise, their concentration is impaired, significantly increasing the likelihood of traffic accidents and posing a serious threat to road safety. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that the above-mentioned equipment, when in use, causes noise to seriously affect the surrounding residents and drivers because the fence cannot absorb sound and reduce noise. Therefore, a hollow structure one-time injection molded combined fence is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hollow structure one-time injection molded combined enclosure, including an enclosure body;
[0006] Both sound-absorbing components are fixedly installed on the outside of the enclosure body to quickly absorb noise generated during construction;
[0007] The sound-absorbing assembly includes a first sound-absorbing panel, a second sound-absorbing panel, and multiple sound-absorbing cottons. The outer wall of the first sound-absorbing panel has multiple sound inlet holes. The second sound-absorbing panel is adhered to one side of the outer wall of the first sound-absorbing panel for initial noise absorption. The outer wall of the second sound-absorbing panel has multiple mounting grooves. Two corrugated plates are fixedly installed on the inner wall of each of the multiple mounting grooves to increase the sound wave reflection path. The multiple sound-absorbing cottons are adhered to the outer wall of the corrugated plates to further absorb sound waves.
[0008] When noise reaches the surface of the enclosure, it first contacts the surface of the first sound-absorbing panel. The first sound-absorbing panel can effectively absorb and reflect some of the sound waves, thus initially weakening the noise. The remaining sound waves then enter the mounting groove through the sound inlet. Under the action of the corrugated plate inside, the sound waves undergo multiple reflections, significantly extending the propagation distance within the cavity and causing most of the sound waves to be converted into heat energy. Subsequently, the remaining sound waves are absorbed when they come into contact with the sound-absorbing cotton and the inner wall of the second sound-absorbing panel, thereby reducing the intensity of noise exposure for residents, reducing health risks, and also reducing the interference of traffic noise on drivers, allowing them to focus more on road conditions and reducing the risk of traffic accidents caused by inattention.
[0009] Preferably, the outer wall of the enclosure body is provided with a set of flow channels, and the output end of the enclosure body is fixedly connected to a drain valve. The flow channels can easily drain water, preventing the water pressure generated by the water accumulation from pushing the enclosure and causing it to deviate from its original position. The drain valve allows the tap water inside the enclosure body to be discharged quickly, thereby facilitating transportation.
[0010] Preferably, the input end of the enclosure body is fixedly connected to a water injection valve, and an insert block is fixedly installed on one side of the outer wall of the enclosure body. Users can inject tap water into the enclosure body through the water injection valve, thereby improving the stability of the enclosure body and reducing the phenomenon of the enclosure body moving due to external forces.
[0011] Preferably, a movable groove is provided on one side of the outer wall of the enclosure body, and a set of vent holes are provided on the inner surface of the movable groove. When two enclosure bodies need to be combined, it is only necessary to insert the plug on one enclosure body into the movable groove of the other enclosure body. As the plug moves forward, the air in the movable groove is discharged through the vent holes. Under the action of air pressure, the plug is not easy to be pulled out of the movable groove, so that the two enclosure bodies can be tightly connected.
[0012] Preferably, the outer wall of the fence body has two display holes, and the top of the fence body has two storage cavities. People can insert warning boards or notice boards into the storage cavities, thereby improving the practicality of the fence body and reducing the time and cost of installing and purchasing corresponding devices.
[0013] Preferably, fluorescent strips are fixedly installed on one side of the outer wall of both sound-absorbing components. The fluorescent strips can emit light at night, allowing people to spot the enclosure body in time and reducing the possibility of accidental collisions.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] 1. In this utility model, when noise comes into contact with the sound-absorbing panel on the surface, some of the sound waves are directly absorbed and reflected to complete the first-layer attenuation. The remaining sound waves enter the cavity through the sound inlet hole and are reflected multiple times under the action of the specially designed corrugated plate, which significantly extends the propagation path and converts most of the sound energy into heat energy. Finally, the residual sound waves are completely absorbed by the sound-absorbing cotton and the inner wall sound-absorbing panel, achieving noise reduction across the entire frequency band. The structure adopts a multi-layer composite noise reduction design and achieves efficient sound energy absorption through a stepped noise reduction mechanism. This not only effectively reduces noise pollution and reduces harm to residents' health, but also significantly improves the traffic environment and reduces the risk of accidents caused by noise interference to drivers.

[0026] Two sound-absorbing components 10 are fixedly installed on the outside of the enclosure body 1 to quickly absorb the noise generated during construction.
[0027] The sound-absorbing component 10 includes a first sound-absorbing panel 1001, a second sound-absorbing panel 1003, and a plurality of sound-absorbing cotton 1006. The outer wall of the first sound-absorbing panel 1001 has a plurality of sound inlet holes 1002. The second sound-absorbing panel 1003 is adhered to one side of the outer wall of the first sound-absorbing panel 1001 for initial noise absorption. The outer wall of the second sound-absorbing panel 1003 has a plurality of mounting grooves 1004. Two corrugated plates 1005 are fixedly installed on the inner wall of each of the plurality of mounting grooves 1004 to increase the sound wave reflection path. The plurality of sound-absorbing cotton 1006 are adhered to the outer wall of the corrugated plate 1005 for further sound wave absorption.
[0028] When noise is transmitted to the surface of the enclosure body 1, it will first come into contact with the surface of the sound-absorbing panel 1001. The sound-absorbing panel 1001 can effectively absorb and reflect part of the sound waves, thereby initially weakening the noise. Then the remaining sound waves come into the installation groove 1004 through the sound inlet 1002. Under the action of the corrugated plate 1005 inside, the sound waves are reflected multiple times, significantly extending the propagation distance in the cavity and causing most of the sound waves to be converted into heat energy. Then the remaining sound waves are absorbed when they come into contact with the sound-absorbing cotton 1006 and the inner wall of the sound-absorbing panel 1003, thereby reducing the intensity of noise exposure for residents, reducing health risks, and also reducing the interference of traffic noise on drivers, allowing them to focus more on road conditions and reducing the risk of traffic accidents caused by inattention.
[0029] like Figures 1-3 As shown, a set of flow channels 2 are provided on the outer wall of the enclosure body 1. A drain valve 3 is fixedly connected to the output end of the enclosure body 1. The flow channels 2 can easily drain the accumulated water, preventing the water pressure generated by the accumulated water from pushing the enclosure and causing it to deviate from its original position. The drain valve 3 allows the tap water inside the enclosure body 1 to be discharged quickly, thus facilitating transportation.
[0030] like Figures 1-3As shown, a water injection valve 4 is fixedly connected to the input end of the enclosure body 1, and an insert block 5 is fixedly installed on one side of the outer wall of the enclosure body 1. Users can inject tap water into the enclosure body 1 through the water injection valve 4, thereby improving the stability of the enclosure body 1 and reducing the phenomenon of the enclosure body 1 moving due to external forces.
[0031] like Figures 1-3 As shown, a movable groove 6 is provided on one side of the outer wall of the enclosure body 1. A set of exhaust holes 7 are provided on the inner surface of the movable groove 6. When two enclosure bodies 1 need to be combined, it is only necessary to insert the plug 5 on one enclosure body 1 into the movable groove 6 of the other enclosure body 1. As the plug 5 moves forward, the air in the movable groove 6 is discharged through the exhaust holes 7. Under the action of air pressure, the plug 5 is not easy to be pulled out of the movable groove 6, so that the two enclosure bodies 1 can be tightly connected.
[0032] like Figures 1-3 As shown, the outer wall of the fence body 1 has two display holes 8, and the top of the fence body 1 has two storage cavities 9. People can insert warning boards or notice boards into the storage cavities 9, thereby improving the practicality of the fence body 1 and reducing the time and cost of installing and purchasing corresponding devices.
[0033] like Figure 1 as well as Figures 4-5 As shown, fluorescent strips 11 are fixedly installed on one side of the outer wall of both sound-absorbing components 10. The fluorescent strips 11 can emit light at night, so that people can notice the enclosure body 1 in time and reduce the possibility of accidental collisions.
