A protective plate 3 is installed on the top of the base 1, and the protective plates 3 are located on both sides of the compressor body 2 respectively; the protective plate 3 can protect the front and rear sides of the compressor body 2, prevent foreign objects from directly colliding with the compressor body 2, and at the same time can also reduce the pollution of sewage and dust, improving the protection effect on the compressor body 2.

[0032] Further, a first noise reduction component for reducing noise diffusion is installed inside the protective plate 3; the first noise reduction component includes a metal hollow plate 4, the metal hollow plate 4 is installed inside the protective plate 3, and both the metal hollow plate 4 and the protective plate 3 are arranged in a U shape. The inside of the metal hollow plate 4 is hollow, and a water inlet hole 5 is opened at the top of the metal hollow plate 4.

The water body can form a water wall to play a role in sound insulation and noise elimination, and at the same time can reduce the mass of the metal hollow plate 4 and improve its portability.

[0033] Specifically, a first sound insulation plate 6 is installed on the side of the metal hollow plate 4 away from the protective plate 3. The bottom of the first sound insulation plate 6 is attached to the top of the base 1, the top of the first sound insulation plate 6 is flush with the top of the metal hollow plate 4, and the inside of the first sound insulation plate 6 is provided with holes with a perforated structure.

After being combined with the protective plate 3, a box structure is formed to wrap the outside of the compressor body 2, achieving the purpose of protecting the compressor body 2. In addition. The inside of the second sound insulation plate 8 is also provided with holes with a perforated structure.
