In the convenient sound insulation maintenance mechanism of the partition plate, the borosilicate glass frame 5 is vacuumized to realize sound insulation through the vacuumizing pipe 6, compared with traditional materials, the borosilicate glass frame 5 is not easy to be affected by high temperature and humidity and to be aged, and the clamping block 4 and the clamping groove 3 are designed to be convenient to dismount and replace, the partition plate does not need to be replaced as a whole, and the maintenance cost and downtime are reduced.

[0022] In one aspect of the embodiment, the first stainless steel sheet 9, the rubber ring 10 and the second stainless steel sheet 11 form a composite sound insulation structure. The air layer formed by the rubber ring 10 has a sound insulation effect, the first stainless steel sheet 9 and the second stainless steel sheet 11 can reflect noise, and the three work together to improve the sound insulation performance. The glass wool 12 connected to the second stainless steel sheet 11 absorbs noise by utilizing its porous characteristics, and the cooperation of multiple materials enhances the overall sound insulation and noise reduction effect. The auxiliary sound insulation mechanism adopts the combination of the first stainless steel sheet 9, the second stainless steel sheet 11, the rubber ring 10 and the glass wool 12. The first stainless steel sheet 9, the second stainless steel sheet 11 and the rubber ring 10 have strong weather resistance, and the glass wool 12 has also enhanced the anti-aging performance through special treatment, improving the durability of the partition plate in harsh working conditions.

[0023] In one aspect of the embodiment, the rear shell plate 13 cooperates with the front shell plate 1 to form protection for the internal sound insulation structure. The anti-collision pad 14 is made of rubber material, and the first anti-skid groove 15 on the surface not only increases the friction, but also can buffer external force when subjected to impact, reducing the vibration and noise generated by the impact of the partition plate, protecting the sound insulation structure from damage and prolonging the service life of the partition plate.

[0024] In one aspect of the embodiment, the rubber pad 16 is fixed on the upper and lower sides of the front shell plate 1 and the rear shell plate 13, and the second anti-skid groove 17 on the surface increases the contact friction with the mounting surface. When the engineering machinery is running and generating vibration, it ensures that the partition plate is stably installed, avoids displacement of the sound insulation structure, and ensures the continuous and stable function of sound insulation and noise reduction.

[0025] The working principle of the utility model is: when the engineering machinery cab partition plate with sound insulation and noise reduction function is used, external noise is first transmitted to the front shell plate 1, at which time the borosilicate glass frame 5 in the convenient sound insulation and maintenance mechanism plays a role, and the inside is extracted into a vacuum state through the vacuum extraction pipe 6. The vacuum environment can greatly weaken the propagation of sound, because sound cannot propagate in a vacuum. At the same time, the structure formed by the first stainless steel sheet 9, the rubber ring 10 and the second stainless steel sheet 11 in the auxiliary sound insulation mechanism utilizes the air layer generated by the rubber ring 10 and the reflection of the stainless steel sheet to reflect and absorb noise. Then, the remaining noise propagates to the glass wool 12, and the porous structure inside the glass wool 12 can convert the sound energy of the noise into heat energy, further absorbing the noise. The anti-collision pad 14 of the protection mechanism can reduce the impact of external collision on the partition plate, avoid additional vibration and noise caused by collision, and the rubber pad 16 of the stable placement mechanism increases the friction with the mounting surface through the second anti-skid groove 17, preventing the partition plate from being displaced due to the vibration of the engineering machinery in operation, and ensuring that the sound insulation structure works stably.

[0026] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
