Technical Field

[0001] This utility model relates to the field of nighttime road construction technology, and more specifically, to a nighttime construction soundproof cover. Background Technology

[0002] Road construction refers to the process of planning, designing, constructing, and maintaining roads through a series of engineering techniques and methods. Over time, road surfaces become damaged, uneven, and prone to potholes, leading to bumpy daily travel, low vehicle traffic efficiency, and frequent traffic accidents. Therefore, road surface renovation and repair are necessary to improve traffic convenience and safety, creating a better travel environment for citizens.

[0003] In the renovation and reconstruction of existing roads, since it is not feasible to carry out road-occupying construction during the day, most construction work needs to be carried out at night. When construction takes place at night, nearby residents are asleep, and the noise generated by the machinery during construction has a significant impact on the lives and sleep of the surrounding residents. In view of this, we propose a soundproof enclosure for nighttime construction. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a soundproof cover for nighttime construction, so as to solve the technical problem that when nearby residents are asleep during nighttime construction, the noise generated by the mechanical equipment during construction has a great impact on the lives and sleep of the surrounding residents.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a soundproof cover for nighttime construction, comprising a base frame mechanism and a soundproof cover body and a lower soundproof mechanism installed on the base frame mechanism. The base frame mechanism includes a keel frame, which includes an upper frame body and a lower frame body. The lower end of the lower frame body is equipped with heavy-duty casters with brakes, and the upper end of the lower frame body has a U-shaped groove. The soundproof cover body includes side screens, a front screen, a top screen, L-shaped columns, and pressure plates. There are four L-shaped columns in total. The L-shaped column array is installed between the upper and lower frame. The lower ends of the side screen and front screen are inserted into the U-shaped groove. The L-shaped columns wrap around the outer sides of both ends of the side screen and front screen. A top screen is provided at the upper end of the side screen and front screen. The top screen is located at the lower end of the upper frame. The inner walls of the side screen and front screen are arrayed with perforated galvanized cover plates. Sound-absorbing cotton is provided inside the perforated galvanized cover plates. The lower sound insulation mechanism includes several lower sound insulation plates rotatably installed at the lower end of the keel frame.

[0006] Preferably, the keel frame is bent at both ends to form a U-shaped structure. The upper frame and the lower frame are both made by bending a single metal rod. The bending angle of the upper frame and the lower frame is 80 degrees to form a U-shaped structure. The two ends of the upper frame and the lower frame are set to open outwards at a wide angle from front to back. An L-shaped bent tie rod is welded to the upper end of the upper frame from the wide angle to connect the two ends of the upper frame. The upper end of the upper frame is provided with an array of lifting rings.

[0007] Preferably, the side screen, front screen, top screen and lower sound insulation plate are all galvanized steel sheets, and the galvanized steel sheets are provided with sound insulation cavities, and the sound insulation cavities are provided with polyester fiber cotton.

[0008] Preferably, the perforated galvanized cover plate is rectangular, and the side screen body is provided with a viewing window, which is vacuum glass. The perforated galvanized cover plate on the side screen body is positioned to avoid the viewing window.

[0009] Preferably, the front end of the sound-absorbing cotton includes evenly distributed recesses and protrusions, the recesses being located between adjacent protrusions, and the recesses and protrusions forming a mountain-shaped structure at the front end of the sound-absorbing cotton.

[0010] Preferably, limit hooks are installed at the lower part of the outer surface of the side screen and the front screen, and several lower sound insulation panels are respectively located below the side screen and the front screen. A transparent rubber strip is provided at the end of the lower sound insulation panel, and a fixing chain is installed at the upper end of the lower sound insulation panel. The end of the fixing chain is hooked onto the limit hook.

[0011] Preferably, there are four pressure plates in total, and the four pressure plates are arranged in an array inside the soundproof cover. The four pressure plates are respectively attached to the side screen and the front screen, and the pressure plates are connected to the L-shaped column by bolts.

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

[0013] 1. This utility model designs a soundproof enclosure and a lower soundproof panel structure. The soundproof enclosure is made of galvanized sheet and has an internal soundproof cavity and polyester fiber cotton, which can effectively block the outward transmission of sound. The lower soundproof panel rotates downward and the transparent rubber strip at the end of the lower soundproof panel can contact the ground, which can prevent the transmission of sound through the gap below the soundproof enclosure. Combined with sound-absorbing cotton, it can effectively reduce the noise generated during construction, giving residents a quiet environment and avoiding the impact of nighttime construction on the surrounding residential areas. It solves the problem that the noise generated by construction has a great impact on the lives and sleep of nearby residents when they are asleep at night.

[0014] 2. This utility model also designs a sound-absorbing cotton structure. The mountain-shaped structure at the front end of the sound-absorbing cotton allows the cotton to reflect sound when it hits the surface. This greatly increases the contact area and reflection path between the sound and the cotton. Moreover, the reflection is not a simple straight line, but rather multiple reflections between the concave and convex shapes of the mountain. During this process, the sound energy is continuously absorbed and consumed by the sound-absorbing cotton material, which can significantly reduce noise.

[0015] 3. This utility model also features a keel frame and a transparent window structure. The two ends of the keel frame are bent into a U-shape and set at a wide angle, which can enhance the stability of this utility model. The wide-angle opening can facilitate the entry of mechanical equipment into the soundproof enclosure for construction. The side screen is provided with a transparent window, which can facilitate the construction personnel to observe the external situation, thereby facilitating the construction work.

Detailed Implementation

[0024] like Figures 1 to 7As shown, this utility model relates to a soundproof cover for nighttime construction, including a base frame mechanism 100 and a soundproof cover body 200 and a lower soundproof mechanism 300 installed on the base frame mechanism 100. The base frame mechanism 100 includes a keel frame 101, which includes an upper frame and a lower frame. The lower end of the lower frame is equipped with heavy-duty casters 103 with brakes, and the upper end of the lower frame has a U-shaped groove 102. The soundproof cover body 200 includes side screens 201, a front screen 202, a top screen 203, L-shaped columns 204, and pressure plates 205. There are four L-shaped columns 204 in total, and the four L-shaped columns 204 are arranged in an array. The system is installed between the upper and lower frame structures. The lower ends of the side screens 201 and front screens 202 are inserted into the U-shaped grooves 102. L-shaped columns 204 wrap around the outer ends of the side screens 201 and front screens 202. A top screen 203 is provided at the upper end of the side screens 201 and front screens 202, located at the lower end of the upper frame. The inner walls of the side screens 201 and front screens 202 are arrayed with perforated galvanized cover plates 209, and sound-absorbing cotton 210 is placed inside the perforated galvanized cover plates 209. The lower sound insulation mechanism 300 includes several lower sound insulation plates 301 rotatably installed at the lower end of the keel frame 101. This invention can effectively reduce construction noise, providing residents with a quiet environment and avoiding the impact of nighttime construction on surrounding residential areas.

[0025] Specifically, both the upper and lower frame structures are made from a single bent metal rod, with both ends bent at an 80-degree angle to form a U-shape. The ends of both the upper and lower frame structures open outwards at wide angles from front to back. An L-shaped bent tie rod 207 is welded to the upper end of the upper frame from the wide-angle point, connecting the two ends of the upper frame. Hanging rings 208 are arrayed at the upper end of the upper frame. The U-shaped, wide-angled design of the keel frame 101 enhances the stability of this invention, and the wide-angle openings facilitate the entry of mechanical equipment into the soundproof enclosure 200 for construction.

[0026] Furthermore, the side screen 201, front screen 202, top screen 203, and lower sound insulation panel 301 are all made of galvanized steel sheet, with a sound insulation cavity inside each galvanized steel sheet, and polyester fiber cotton 211 is placed inside the sound insulation cavity. The polyester fiber cotton 211 can absorb sound and effectively block and reduce the outward transmission of sound.

[0027] It is worth noting that the perforated galvanized cover plate 209 is rectangular, and the side screen 201 has a viewing window 206, which is made of vacuum glass. The perforated galvanized cover plate 209 on the side screen 201 is positioned to avoid the viewing window 206. The viewing window 206 allows construction personnel to easily observe the external environment, thus facilitating construction work.

[0028] It is worth mentioning that the front end of the sound-absorbing cotton 210 includes evenly distributed recesses and protrusions. The recesses are located between adjacent protrusions, and the recesses and protrusions form a mountain-shaped structure at the front end of the sound-absorbing cotton 210. This mountain-shaped structure at the front end of the sound-absorbing cotton 210 greatly increases the contact area and reflection path when sound impacts its surface. Furthermore, the sound is not simply reflected in a straight line, but rather reflects multiple times between the concave and convex parts of the mountain shape. During this process, sound energy is continuously absorbed and dissipated by the sound-absorbing cotton material, significantly reducing noise.

[0029] It is worth noting that limit hooks 304 are installed at the lower part of the outer surface of both the side screen 201 and the front screen 202. Several lower sound insulation panels 301 are located below the side screen 201 and the front screen 202, respectively. A transparent rubber strip 303 is provided at the end of each lower sound insulation panel 301, and a fixing chain 302 is installed at the upper end of each lower sound insulation panel 301. The end of the fixing chain 302 is hooked onto the limit hook 304. The limit hook 304 and the fixing chain 302 can fix the lower sound insulation panel 301, keeping it in a horizontal position. Loosening the connection between the fixing chain 302 and the limit hook 304 allows the lower sound insulation panel 301 to rotate downwards, and the transparent rubber strip 303 at the end of the lower sound insulation panel 301 can contact the ground, preventing the transmission of sound through the gaps below the sound insulation enclosure 200.

[0030] Furthermore, four pressure plates 205 are provided in total, arranged in an array within the soundproof enclosure 200. The four pressure plates 205 are respectively attached to the side screen 201 and the front screen 202, and are connected to the L-shaped column 204 by bolts. While the L-shaped column 204 limits the movement of the side screen 201, the front screen 202, and the top screen 203, the pressure plates 205, through bolts, connect the side screen 201, the front screen 202, and the top screen 203 to the L-shaped column 204, improving the stability of the soundproof enclosure 200 installation.

[0031] Working Principle: This embodiment provides a soundproof cover for nighttime construction. Each component of this invention is an independent bolt-mounted part, facilitating transportation. During use, it is assembled so that it is positioned above the road construction site. Loosening the connection between the fixing chain 302 and the limiting hook 304 allows the lower soundproof panel 301 to rotate downwards to a vertical position, enabling the transparent rubber strip 303 to contact the ground. During nighttime construction, workers rotate the door panel 205 to enter the soundproof cover for work. Noise generated during construction is blocked by the soundproof cover body 200, and sound is absorbed by the polyester fiber cotton 211, effectively preventing sound transmission outwards. The lower sound insulation panel 301 can be rotated downwards to prevent the transmission of sound through the gaps below the sound insulation cover 200, thus achieving a certain noise reduction effect. Inside the sound insulation cover 200, the mountain-shaped sound-absorbing cotton 210 can reflect sound, greatly increasing the contact area and reflection path between the sound and the sound-absorbing cotton. When sound waves hit the surface of the sound-absorbing cotton 210, they are no longer simply reflected in a straight line, but are reflected multiple times between the concave and convex shapes of the mountain. During this process, the sound energy is continuously absorbed and consumed by the sound-absorbing cotton material. The cooperation of these factors significantly reduces noise, providing residents with a quiet environment and avoiding the impact of nighttime construction on the surrounding residential areas.

[0032] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
