Description

Technical Field

[0001] The utility model relates to the field of noise suppression equipment, in particular to construction noise suppression equipment. Background Art

[0002] The noise generated by construction sites can cause disturbance and discomfort to the surrounding environment and residents' lives, affecting their work, rest and health. In order to reduce this impact, measures need to be taken to reduce the level of construction noise, including the use of sound insulation equipment. These devices can effectively isolate construction noise and reduce its spread to the surrounding environment, thereby improving the quality of life of residents and ensuring the comfort of the urban environment.

[0003] Existing technologies mainly include sound-absorbing materials, low-noise machinery and equipment, and soundproof covers. Sound-absorbing materials can absorb noise and reduce its reflection, and are often used to cover walls, ceilings and floors. Low-noise machinery and equipment reduce the noise generated during operation through optimized design and technical improvements. Soundproof covers can wrap up the noise source and prevent the noise from spreading to the surrounding environment. The combined application of these technologies can help reduce the noise level on construction sites and improve the surrounding environment and the quality of life of residents.

The main reasons include that the installation process requires a lot of time and human resources, and the installation process requires large-scale changes to the construction site, which increases the complexity and cost of construction. In addition, the existing sound insulation equipment is not flexible enough to adapt to noise sources of different shapes and sizes, resulting in the need for customization or adjustment during the installation process, which further prolongs the installation time. Therefore, a construction noise suppression device is proposed to solve the above problems. Utility Model Content

[0029] Working principle: When the construction site starts to assemble the noise suppression equipment, push the multiple devices needed together and then start splicing. The staff needs to splice the two adjacent sound insulation devices in the order of connecting block 2 3, frame 1, connecting block 1 2, and connecting block 2 3. First, when the sound insulation equipment is not connected, the two clamps 4 in the connecting block 1 2 are open, and the push rod 5 is pulled out of the connecting block 1 2 by the two clamps 4. At this time, the left side of the support rod 7 is not stuck in the fixing groove 1 at the bottom of the push rod 5, but because the push rod 5 moves to the right and is stuck on the lower surface of the push rod 5. At this time, it is necessary to clarify that the spring 9 is compressed and contracted by the right end of the support rod 7. When any two sets of connecting blocks 1 2 and connecting blocks 2 3 are in contact, the push rod 5 in the connecting block 1 2 will be pushed to the left by the connecting rod 10 on the connecting block 2 3 of another sound insulation device. At this time, due to the movement of the push rod 5, the clamps 4 on both sides of the push rod 5 will shrink and slowly clamp toward the middle. When the push rod 5 is pushed to the left, the two clamps 4 will completely clamp the clamping block 11 of another sound insulation device, and the limit block 6 will press against the inside of the connecting block 2. At this time, the fixing groove 1 at the lower part of the push rod 5 will be The second fixing groove at the bottom of the connecting block 1 2 will be vertically overlapped. At this time, since the left end of the support rod 7 is already suspended, the protruding part of the left end will be stuck in the fixing groove 1 and the fixing groove 2 under the pressure of the spring 9 at the right end, thereby locking the push rod 5 to prevent the push rod 5 from moving and causing the splicing to fail, thereby ensuring that the two clamps 4 firmly clamp the clamping blocks 11 will not loosen. When multiple sound insulation devices are spliced, the crank 15 at the rear of each sound insulation device can be turned to push out the expansion board 12 stored in the frame 1, and the expansion board 12 can 0 is pushed up, so that the sound insulation range can be expanded. The construction noise can be effectively prevented from spreading under the obstruction of the sound insulation board 1 20 and the sound insulation board 2 21. When the construction is completed, first turn back the crank 15 to retract the expansion board 12 into the frame 1. When splitting multiple sound insulation devices, you only need to press the two support rods 7 of each sound insulation device against the push rod 5 to lose support. At this time, the two clamps 4 of the connecting block 1 2 will lose any resistance, and the two connected sound insulation devices can be separated. After the splitting, the multiple sound insulation devices can be pushed away and stored.
