Description

Technical Field

[0001] The utility model relates to the technical field of sound barriers, in particular to an elevated road closed sound barrier capable of preventing snow accumulation. Background Art

[0002] Closed sound barriers are mainly used for sound insulation and noise reduction on roads, highways, elevated composite roads and other noise sources. They are divided into pure sound insulation reflective sound barriers and composite sound barriers that combine sound absorption and sound insulation. The latter is a more effective sound insulation method. It refers to wall structures set up on the side of railways and roads to reduce the impact of traffic noise on nearby residents.

[0003] Among them, the "enclosed sound barrier" disclosed by the authorization number "CN219450493U" has a specific technical structure that positions the device base and the closed sound barrier plate through positioning holes, making it convenient for subsequent staff to connect the device base and the closed sound barrier plate;

[0004] Although the above-mentioned closed sound barrier solves the problem of difficulty in installation due to the small number of positioning mechanisms, due to the open top, a large amount of snow is likely to accumulate on the elevated road when encountering rainy and snowy weather, causing the wheels of vehicles to slip easily when driving on the elevated road. The above-mentioned closed sound barrier does not solve the problem of preventing snow accumulation in rainy and snowy weather, so that when the closed sound barrier is used on the elevated road, vehicles are prone to traffic accidents.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a closed sound barrier for an elevated road that can prevent snow accumulation. Through the limiting mechanism of the first limiting groove and the card block, the supporting keel frame is installed between the closed sound barrier panels of the elevated road to support the anti-snow arc plates, so that the anti-snow arc plates can protect the elevated road from snow accumulation. The limiting mechanism formed by the locking of the semicircular ring buckle and the U-shaped buckle makes the connection between the anti-snow arc plates more firm and tight, preventing snow from sliding through the gaps onto the elevated road on snowy days, and solving the problem of vehicles slipping or being blocked due to the accumulation of a large amount of snow or ice on the elevated road surface on snowy days.

[0024] 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.

[0025] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a closed sound barrier for an elevated road that can prevent snow accumulation.

[0026] See also Figure 1 - Figure 5 , an elevated road closed sound barrier capable of preventing snow accumulation, comprising an elevated road closed sound barrier board 1, an anti-snow arc board 2 movably mounted on the top of the elevated road closed sound barrier board 1, and a supporting keel frame 3, a fixing block 201 is fixedly mounted at the rear end of the bottom of the anti-snow arc board 2, a U-shaped buckle 202 is fixedly mounted at the front end of the bottom of the anti-snow arc board 2, a rotating rod 203 is rotatably mounted inside the fixing block 201, a semicircular ring buckle 204 is movably mounted inside the fixing block 201, and a connecting rod 205 is fixedly mounted between one end of the rotating rod 203 and the semicircular ring buckle 204;

[0027] The supporting keel frame 3 is movably installed at the top between the elevated road closed sound barrier panels 1. A second limiting groove 303 is opened on the inner side of the top of the elevated road closed sound barrier panels 1. Blocks 301 are fixedly installed on both sides of the supporting keel frame 3. The block 301 slides into and is installed inside the second limiting groove 303.

[0028] Specifically, the supporting keel frame 3 is installed between the closed sound barrier panels 1 of the elevated road through the limiting mechanism of the first limiting groove 101 and the blocking block 301, and then the supporting keel frame 3 supports the anti-snow arc plate 2 so that the anti-snow arc plate 2 is installed on the top of the closed sound barrier panels 1 of the elevated road to protect the elevated road from snow accumulation. The anti-snow arc plate 2 has an arc surface, and the accumulated snow will slide down the arc surface to avoid the gravity of the accumulated snow from causing pressure on the anti-snow arc plate 2. The semicircular ring buckle 204 is driven to rotate by the rotating rod 203, so that the semicircular ring buckle 204 passes through the inside of the U-shaped buckle 202 to form a limiting mechanism, so that the connection between the anti-snow arc plate 2 and the anti-snow arc plate 2 is more firmly and tightly connected, thereby preventing snow from sliding through the gap onto the elevated road on snowy days and then freezing due to the low temperature, thereby solving the problem of vehicles slipping or being blocked due to the accumulation of a large amount of snow or ice on the elevated road surface on snowy days.

[0029] Furthermore, a first limiting groove 101 is provided on the outer side of the top of the elevated road closed sound barrier board 1, and limiting blocks 4 are fixedly installed on both sides of the bottom of the anti-snow arc plate 2, and the limiting blocks 4 are slid into and installed in the first limiting groove 101, and a cavity 102 is provided inside the top of the elevated road closed sound barrier board 1, and a limiting rod 103 is movably installed inside the cavity 102, and a baffle 104 is fixedly installed on the outer side of the limiting rod 103 inside the cavity 102, and a spring 105 is sleeved and installed on the outer side of the limiting rod 103 inside the cavity 102;

[0030] Specifically, the limiting block 4 slides into the first limiting groove 101, and then due to the elastic force of the spring 105 acting on the baffle 104, one end of the limiting rod 103 slides into the circular hole inside the limiting block 4 to limit the limiting block 4, so that the anti-snow arc plate 2 is fixedly installed on the top of the closed sound barrier plate 1 of the elevated road, so that the anti-snow arc plate 2 is more firmly used to prevent snow accumulation on the elevated road;

[0031] Furthermore, a mounting groove 106 is provided on the inner side of the elevated road closed sound barrier board 1, a sound absorbing board 107 is fixedly installed inside the mounting groove 106, a sound insulation board 108 is fixedly installed inside the mounting groove 106 by bolts on the inner side of the elevated road closed sound barrier board 1, and sound absorbing holes 109 are evenly provided inside the sound insulation board 108;

[0032] Furthermore, solar panels 206 are fixedly installed on both sides of the top of the anti-snow arc plate 2, a fixing rod 207 is fixedly installed on the bottom of the anti-snow arc plate 2, and a lighting lamp 208 is fixedly installed on the bottom of the fixing rod 207, and the solar panel 206 and the lighting lamp 208 are electrically connected;

[0033] Specifically, when a vehicle is traveling on the elevated road, the noise emitted is first blocked by the sound insulation board 108. When the noise is too loud, it is absorbed by the sound absorbing board 107 inside the installation groove 106 through the sound absorbing hole 109 to reduce the noise, thereby preventing the vehicle noise on the elevated road from affecting the lives of urban residents. At the same time, the solar panel 206 converts solar energy into electrical energy to power the lighting lamp 208, so that the lighting lamp 208 illuminates the elevated road, thereby avoiding the situation where the elevated road is dark due to the light shielding of the anti-snow arc plate 2, thereby increasing the danger of vehicle driving.

[0034] Furthermore, grooves 302 are provided on both sides of the top of the supporting keel frame 3, and support beams 209 are fixedly installed on both sides of the bottom of the anti-snow arc plate 2, and the support beams 209 are slid into and installed in the grooves 302;

[0035] Furthermore, a base 5 is movably installed at the bottom of the elevated road closed sound barrier board 1, a slide groove 501 is opened at the top of the base 5, and a slide bar 502 is slidably installed inside the slide groove 501 and fixed to the bottom of the elevated road closed sound barrier board 1;

[0036] Specifically, when the anti-snow arc plate 2 is installed on the top of the elevated road closed sound barrier plate 1, the support beam 209 slides into the interior of the groove 302, so that the anti-snow arc plate 2 is installed more stably, and the sliding bar 502 slides into the interior of the slide groove 501, so that the elevated road closed sound barrier plate 1 is installed on the top of the base 5, so that the elevated road closed sound barrier plate 1 is more stably installed on the elevated road.

[0037] Working principle: First, the staff slides into the slide groove 501 through the slide bar 502 to install the elevated road closed sound barrier panel 1 on the top of the base 5, and then installs the block 301 inside the second limiting groove 303, so that the supporting keel frame 3 is installed between the tops of the elevated road closed sound barrier panel 1, and then installs the anti-snow arc plate 2 on the top of the supporting keel frame 3. At this time, the support beam 209 slides into the groove 302, and the limiting block 4 slides into the first limiting groove 101. Due to the elastic force of the spring 105 acting on the baffle 104, one end of the limiting rod 103 slides into the circular hole inside the limiting block 4, so that the anti-snow arc plate 2 The arc plate 2 is fixedly installed on the top of the closed sound barrier plate 1 of the elevated road, and then the staff rotates the rotating rod 203 counterclockwise, so that the rotating rod 203 drives the semicircular ring buckle 204 to rotate counterclockwise through the connecting rod 205, so that the semicircular ring buckle 204 passes through the fixed block 201 and slides out and then passes through the inner side of the U-shaped buckle 202 for limiting, so that the connection between the anti-snow arc plate 2 and the anti-snow arc plate 2 is more secure. When encountering snowy days, the snow accumulated on the top of the anti-snow arc plate 2 will not fall on the elevated road surface. Since the anti-snow arc plate 2 is a curved surface, the snow slides along the curved surface, avoiding the situation where vehicles slip or get blocked due to snow on the elevated road.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
