[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model. However, it should not be construed as a limitation on the protection scope of the present utility model.

[0024] Referring to Figure 1 - Figure 4 , a noise reduction and dust prevention device for municipal engineering, comprising a bottom plate 1: on the upper sides of the left and right ends of the bottom plate 1, fixing plates 3 are fixedly connected. An installation unit 7 is arranged on the front side of the fixing plate 3. A top plate 4 is fixedly connected to the upper side of the fixing plate 3. Installation blocks 2 are fixedly connected to the front and rear sides of the bottom plate 1. Circular holes are formed in the installation blocks 2, which is convenient to use bolts to match with the installation blocks 2, facilitating the installation of the dust prevention device.

[0025] The installation unit 7 includes a placement groove 701 which is opened on the front side of the fixed plate 3. A dust-proof frame 702 is arranged inside the placement groove 701. Installation holes 703 are opened on the front sides of the left and right ends of the dust-proof frame 702. Chute grooves 704 are opened on the front sides of the left and right fixed plates 3. A slider 705 is slidably connected inside the chute grooves 704. A moving plate 706 is fixedly connected to the front side of the slider 705. A pull rod 709 is arranged on the outer side of the moving plate 706. The rear end of the pull rod 709 is fixedly connected to a mounting plate 708. A stabilizing rod 707 is fixedly connected to the rear side of the mounting plate 708. A spring 711 is fixedly connected between the mounting plate 708 and the moving plate 706. The front end of the pull rod 709 is fixedly connected to a pull plate 710. A sound-absorbing plate 8 is fixedly connected between the left and right fixed plates 3. The stabilizing rod 707 is adapted to the installation hole 703. A circular groove 712 is opened on the front side of the fixed plate 3 and is adapted to the stabilizing rod 707. The pull rod 709 is slidably connected to the moving plate 706. The moving plate 706 is arranged in an L-shaped structure. The dust-proof frame 702 is adapted to the placement groove 701. During use, a dust-proof net is installed inside the dust-proof frame 702, which is convenient for blocking the dust at the construction site, and the sound is absorbed by the sound-absorbing plate 8. When the dust-proof frame 702 needs to be disassembled, the pull plate 710 is pulled. The pull plate 710 drives the pull rod 709 to move. The pull rod 709 drives the mounting plate 708 to move. The mounting plate 708 drives the stabilizing rod 707 to move, so that the stabilizing rod 707 is separated from the installation hole 703. Then the pull plate 710 is horizontally moved, so that the pull plate 710 drives the moving plate 706 to move. The moving plate 706 drives the slider 705 to slide inside the chute groove 704. Then the dust-proof frame 702 can be directly disassembled, which is convenient for quickly replacing the new dust-proof frame 702. When a new dust-proof frame 702 needs to be installed, the new dust-proof frame 702 is placed in the placement groove 701, and the pull plate 710 is pulled, so that the pull plate 710 drives the stabilizing rod 707 to move, and the pull plate 710 is moved. At this time, the spring 711 is compressed. Under the action of the spring 711, when the hand is released, the spring 711 drives the stabilizing rod 707 and the mounting plate 708 to move. The mounting plate 708 is in close contact with the dust-proof frame 702, so that the stabilizing rod 707 is inserted into the installation hole 703, which is convenient for quickly installing the dust-proof frame 702, and the operation is simple.

[0026] A mounting frame 5 is fixedly connected to the left side of the left fixed plate 3. A clamping plate 6 is fixedly connected to the right side of the right fixed plate 3. The mounting frame 5 is adapted to the clamping plate 6. During installation, the multiple dust-proof devices are clamped together through the clamping connection of the mounting frame 5 and the clamping plate 6.

[0027] Working principle: When in use, the dust-proof frame 702 and the sound-absorbing plate 8 facilitate dust-proofing and noise reduction. When the dust-proof frame 702 needs to be replaced, pull the pull plate 710. The pull plate 710 drives the stabilizing rod 707 on the mounting plate 708 to move, and horizontally move the pull plate 710 so that the stabilizing rod 707 moves to the circular groove 712 on the fixing plate 3, and then the dust-proof frame 702 can be directly disassembled. When replacing, place the new dust-proof frame 702 in the placement groove 701, pull the pull plate 710, horizontally move the pull plate 710, and then release it. Under the action of the elastic force of the spring 711, the mounting plate 708 is closely attached to the dust-proof frame 702, and the stabilizing rod 707 is connected to the mounting hole 703, so that the dust-proof frame 702 is quickly installed, and the operation is simple.

[0028] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
