DETAILED DESCRIPTION

[0021] In order to deepen the understanding of the utility model, the utility model will be further described in the following combining with examples and drawings, the examples are only used to explain the utility model, and do not constitute the limitation to the protection scope of the utility model.

[0022] As Figures 1-4 Indicated, the embodiment of the utility model provides a prefabricated cabin structure with sound insulation and noise reduction function, including bottom plate 100, side plate 120 and top plate 110, the outside of side plate 120 is equipped with drain pipe 130, bottom plate 100 includes anti-skid layer 15, first support layer 12, first sound insulation layer 11, second support layer 9 and second sound insulation layer 8, anti-skid layer 15 includes inclined plate 1 and flat plate 14, inclined plate 1 is 10-15 degrees with horizontal plane Angle, inclined plate 1 is equipped with on the left and right sides of flat plate 14;Anti-skid layer 15 is installed on first support layer 12, first support layer 12 is composed of support plate 13 and support leg 10, support plate 13 is fixed with anti-skid layer 15, the bottom of bottom plate 100 is equipped with several fixed plates 3, fixed plate 3 is equipped with contact plate 4, fixed plate 3 is contacted with support leg 10, contact plate 4 is equipped with second support layer 9, second support layer 9 is equipped with second sound insulation layer 8, second sound insulation layer 8 and first support layer 12 are equipped with containing space, and first sound insulation layer 11 is equipped in containing space.

[0023] Specifically, the bottom plate 100 is the lowermost structure of the prefabricated cabin, and the main function of the bottom plate 100 is to provide support for the cabin body, and at the same time, through the multi-layer structure, the sound insulation, noise reduction and anti-skid effects are achieved, and the entire cabin body is supported and contacted with the ground. The bottom plate 100 is designed as a multi-layer structure, which can effectively block the noise and vibration from the ground; the anti-skid layer 15 is composed of inclined plates 1 and flat plates 14, the inclined plates 1 are at an angle of 10-15 degrees with the horizontal plane and are located on the left and right sides of the flat plates 14. This design makes the drainage and anti-skid effects more remarkable. After cleaning with water, only the mop is needed to mop the water to the drain pipe 130. The anti-skid drainage groove 140 on the anti-skid layer 15 not only prevents sliding, but also effectively guides the water flow, avoids water accumulation and reduces the corrosion problem caused by moisture on the bottom plate 100. The first support layer 12 is composed of a support plate 13 and a support leg 10. The support plate 13 is fixed with the anti-skid layer 15, and the support leg 10 provides support for the bottom plate 100. The support leg 10 is in contact with the fixed plate 3, so that the contact area of the support leg 10 with the ground is smaller, the vibration transmitted is reduced, and the deformation or settlement of the anti-skid layer 15 caused by heavy pressure during long-term use is avoided. The second support layer 9 is a structure between the contact plate 4 and the second sound insulation layer 8, which is made of vibration absorption material, further blocks the low-frequency noise and vibration from the ground, and also plays a supporting role. The second sound insulation layer 8 is a layer of sound insulation material arranged on the second support layer 9 and positioned in the gap formed by the second support layer 9 by the positioning block 7. The second sound insulation layer 8 not only plays a sound insulation role, but also is used to support the first sound insulation layer 11. The first sound insulation layer 11 is arranged on the upper side of the second sound insulation layer 8 and can be a block structure or a laminated plate structure. Due to the effect of the second sound insulation layer 8 and the first support layer 12, the first sound insulation layer 11 does not need to bear the force, so a more flexible sound insulation material can be selected to further enhance the sound insulation effect.

The large prefabricated noise reduction prefabricated cabin provided by the utility model can be applied in these scenarios as a noise reduction device to isolate the internal equipment noise from being transmitted outside. In another application scenario, for example, in a large casting workshop, a forging plant or other high-noise industrial environment, the noise generated by the equipment running inside the workshop will adversely affect the health and work efficiency of the employees. Therefore, management and technical personnel often need to work or monitor the production process in the workshop, and thus a quiet and comfortable office space is needed. The cabin structure of the utility model can be quickly built inside the workshop to form an independent small soundproof office, providing a quiet working environment for management and technical personnel.

[0027] Further, the left and right sides of the wide part 5 are respectively provided with a contact plate 4, the height of the contact plate 4 is lower than the height of the narrow part 6, and thus through the design, by adjusting the material of the contact plate 4, the support effect can be further improved.

[0028] Further, the second support layer 9 is arranged in the space formed by the two narrow parts 6, the second support layer 9 is in contact with the contact plate 4 on one narrow part 6 and the contact plate 4 on the other narrow part 6, and the support effect is further improved.

[0029] Further, the second sound insulation layer 8 comprises a positioning block 7, the positioning block 7 is arranged in the gap formed by the two second support layers 9, so that the second sound insulation layer 8 is better fixed.
