Technical Field

[0001] The utility model relates to the technical field of environmental protection noise reduction, and more specifically to an environmental protection noise reduction device for building construction management. Background Art

[0002] Construction noise is mainly generated by sound sources such as mechanical equipment, heavy vehicles, high-altitude operations and personnel activities, which will have a negative impact on the surrounding environment and residents. In order to ensure the circular nature of the construction, a barrier wall will be set up outside the construction area to achieve the effect of noise reduction.

[0003] After searching, the existing patent (publication number: CN219887740U) discloses an environmentally friendly noise reduction device for construction management. When in use, the extension plate can be pulled up to extend the height of the barrier, which is convenient for use. In addition, the extension plate is fixed by a pull handle, a limit column, a limit hole, a spring, a vertical plate, etc. to ensure overall stability. The protrusion on one side is inserted into the groove on the adjacent barrier and fixed with bolts. The whole is tightly fitted without gaps, ensuring the effect of environmental noise reduction. However, the inventor found that the prior art has the following problems in the process of realizing the utility model: the above-mentioned environmental noise reduction device, because the extension plate is stored inside the barrier, the width of the extension plate is smaller than the width of the barrier. In this case, during use, several barriers are tightly connected, but there are still gaps between several extension plates, resulting in leakage points of protection. In view of this, the utility model proposes an environmentally friendly noise reduction device for construction management with good protection effect to solve this problem. Utility Model Content

[0028] When the environmentally friendly noise reduction device for construction management is in use, the barrier panel 1 is moved to the periphery of the construction area, and the connecting panel 3 and the barrier panel 1 are first positioned by inserting the plug 4 into the ground, and then the plug block 5 is inserted into the slot 6 to assemble two adjacent barrier panels 1, so that several barrier panels 1 are combined into a continuous wall structure, and the barrier panels 1 are used to perform noise reduction and isolation protection for low-lying environmental locations.

[0029] A positioning groove 15 is formed on the surface of the insert block 5 , and a slope is formed on the left side of the positioning groove 15 . A positioning pin 16 is threadedly connected to the corresponding slot 6 on the front side of the barrier plate 1 , and the positioning pin 16 is matched with the positioning groove 15 .

[0030] By providing the positioning groove 15 and the positioning pin 16, during the assembly process, after the plug block 5 is inserted into the slot 6, the screwing positioning pin 16 is inserted into the positioning groove 15, which can lock the plug block 5 to prevent the plug block 5 from falling out, and during the locking process, when the positioning pin 16 slides with the inclined surface provided on the surface of the positioning groove 15, the plug block 5 can be driven to move deeper into the slot 6, so that the operator can more conveniently assemble the two barrier panels 1 tightly.

[0031] The extension component includes a limiting slide groove opened on the back of the barrier plate 1, and a limiting slide rod 7 is embedded inside the limiting slide groove. The number of the limiting slide groove and the limiting slide rod 7 are both two. The two limiting slide grooves are symmetrically arranged on the back of the barrier plate 1.

The extension plate 8 is fixed at a high position, which cooperates with the external building to partition the high space, thereby isolating and reducing noise for the high space. Moreover, since the width of the extension plate 8 is the same as that of the barrier plate 1, the isolation can be more seamless, ensuring the isolation and noise reduction effect.

The worm 12 is meshed with the worm wheel 14, thereby driving the connecting shaft 2 to rotate, and the connecting plate 3 can be flipped and adjusted to a state where the universal wheel 11 is in contact with the ground. The barrier plate 1 is supported on the ground with the universal wheel 11, so that the barrier plate 1 can be easily moved, thereby improving the convenience during use.

[0038] A limiting support plate 19 for limiting the descending height of the extension plate 8 is fixedly mounted on the back of the barrier plate 1 , and a buffer pad 20 is arranged on the surface of the limiting support plate 19 .

[0039] Furthermore, by providing a limit support plate 19, when the height of the extension plate 8 is lowered, the locking pin 9 is pulled by the handle 18 to disengage the locking pin 9 from the locking groove 10, thereby canceling the braking of the extension plate 8. Under the action of gravity, the height of the extension plate 8 is lowered, and the limit support plate 19 can be used to limit the lowering height of the extension plate 8. By providing the buffer pad 20, the lowered extension plate 8 can be buffered to avoid excessive collision, thereby achieving the effect of protecting the entire device.
