Description

Technical Field

[0001] The utility model relates to the technical field of generator sets, in particular to a sound insulation door used in a generator set site. Background Art

[0002] A generator set is a type of power generation equipment that uses diesel, gasoline, etc. as fuel to convert other forms of energy into electrical energy. Generator sets are widely used in industrial and agricultural production.

[0003] When the generator set is working, it will generate a lot of noise, which can easily cause people to lose concentration and reduce work quality. If they are in a noisy environment for a long time, it may also cause deafness and other phenomena in the workers. At present, in order to reduce the noise during the production of the generator set, the generator set is usually placed in a silent box for operation, and a soundproof door is installed on the silent box. The noise is blocked by the silent box and the soundproof door to reduce noise pollution. However, the existing soundproof door has a simple structure and poor sound insulation effect. It can only block most of the noise. Some noise still comes out from the soundproof door, affecting people's daily life.

[0004] Therefore, there is an urgent need for a soundproof door for a generator set site to solve the above problems. Utility Model Content

[0018] By setting up the sound insulation layer and the silent strip, when the generator set is working, the noise is first reflected and consumed in the second sound insulation hole on the second sound-absorbing panel to initially reduce the noise, and then reflected and consumed in the first sound insulation hole on the first sound-absorbing panel to further reduce the noise. The residual sound is then absorbed by the sound insulation layer to achieve the effect of noise elimination, so that the noise will not be transmitted to the outside, reducing noise pollution. At the same time, the silent strip is detachably connected to the outer frame, which is convenient for the staff to replace the aging silent strip in time, ensuring that the noise will not be transmitted from the gap between the cavity and the outer frame, thereby improving the noise blocking effect of the soundproof door.

[0031] In one embodiment of the present invention, Figure 1-5 As shown, a soundproof door for a generator site is provided, comprising a wall 10 and a soundproof door body 20. The soundproof door body comprises an outer frame 21 and an inner layer 22. The outer frame 21 is rotatably connected to the wall 10. Multiple sets of quiet strips 23 are provided between one side of the outer frame 21 and the wall 10. The quiet strips 23 are detachably connected to the outer frame 21. The inner layer 22 is disposed within the outer frame 21. The inner layer 22 comprises a reinforcing layer 30, a sound-absorbing layer 31, and a flame-retardant layer 32. The reinforcing layer 30 is disposed within the outer frame 21 to enhance the overall strength of the inner layer 22. The sound-absorbing layer 31 is disposed on the reinforcing layer 30 to block noise. The flame-retardant layer 32 is disposed on the sound-absorbing layer 31 to improve the flame retardancy of the inner layer 22. The sound-absorbing layer 31 comprises a sound insulation layer 311. First sound-absorbing panels 312 are provided on both sides of the sound insulation layer 311. A second sound-absorbing panel 314 is disposed on the first sound-absorbing panel 312.

[0032] In this embodiment, the reinforcement layer 30 is made of aluminum honeycomb material. By providing the reinforcement layer 30 , the strength of the inner layer 22 is improved, thereby increasing the service life of the soundproof door body 20 .

[0033] The flame retardant layer 32 is made of flame retardant fiber material. By providing the flame retardant layer 32 , the flame retardancy of the inner layer 22 is improved, thereby making the sound insulation door body 20 less likely to burn and increasing its service life.

[0034] By providing the sound insulation layer 311 and the silent strip 23, when the generator set is working, the noise first continuously reflects and consumes the energy of the noise in the second sound insulation hole on the second sound absorbing panel 314, thereby initially reducing the noise, and then continuously reflects and consumes the energy of the noise again in the first sound insulation hole on the first sound absorbing panel 312, thereby further reducing the noise. The residual sound is then absorbed by the sound insulation layer 311, thereby achieving the effect of noise elimination, so that the noise will not be transmitted to the outside, thereby reducing noise pollution. At the same time, the silent strip 23 is detachably connected to the outer frame 21, which makes it convenient for the staff to replace the aging silent strip 23 in time, ensuring that the noise will not be transmitted from the gap between the cavity and the outer frame 21, thereby improving the noise blocking effect of the soundproof door.

[0035] Preferably, the first sound absorbing plate 312 is provided with multiple groups of first sound absorbing holes 313. The multiple groups of first sound absorbing holes 313 are evenly spaced on the first sound absorbing plate 312. Providing multiple groups of first sound absorbing holes 313 allows noise to be continuously reflected within the first sound absorbing holes 313, thereby consuming noise energy and achieving a preliminary noise reduction effect.

[0036] Furthermore, the second sound-absorbing plate 314 is provided with multiple groups of second sound-absorbing holes 315. These groups of second sound-absorbing holes 315 are evenly spaced throughout the second sound-absorbing plate 314. By providing these multiple groups of second sound-absorbing holes 315, the noise that has undergone initial noise reduction is continuously reflected within the second sound-absorbing holes 315, further consuming the noise's energy and providing secondary noise reduction, thereby minimizing noise and improving the noise-blocking effectiveness of the soundproof door body 20.

[0037] Furthermore, the inner diameter of the first sound-absorbing hole 313 is smaller than the inner diameter of the second sound-absorbing hole 315. Sound-absorbing cotton 316 is provided in both the first and second sound-absorbing holes 313, 315. By providing the sound-absorbing cotton 316 in the first and second sound-absorbing holes 313, 315, the reflection path of noise within the first and second sound-absorbing holes 313, 315 is extended, effectively reducing energy consumption of the noise and achieving a noise reduction effect.

[0038] Preferably, the bottom end of the noise reduction strip 23 is provided with a protrusion 231. A flexible strip 232 extending outward from the protrusion 231 has a certain elasticity. A slot is provided between the outer frame 21 and the protrusion 231. The provision of the flexible strip 232 allows the protrusion 231 to be securely engaged in the slot. The flexible strip 232 also provides a certain elasticity, facilitating removal of the protrusion 231 from the slot and simplifying the installation and removal of the noise reduction strip 233 from the outer frame 21.

[0039] Furthermore, the convex head 231 and the elastic strip 232 are integrally formed. By integrally forming the convex head 231 and the elastic strip 232, the processing steps are simplified and the cost expenditure is reduced.

[0040] Preferably, a moisture-proof layer 33 is provided on the reinforcement layer 30 and is fixedly connected to the reinforcement layer 30. In this embodiment, the moisture-proof layer 33 is an epoxy resin sheet. By providing the moisture-proof layer 33, the moisture resistance of the inner layer 22 is improved, and the soundproof door body 20 is prevented from mold due to excessive humidity, thereby increasing the service life of the soundproof door body 20.

[0041] Furthermore, a heat insulating layer 34 is provided on the moisture-proof layer 33, and the moisture-proof layer 33 is fixedly connected to the heat insulating layer 34. In this embodiment, the heat insulating layer 34 is ceramic fiber or rock wool. By providing the moisture-proof layer 33, the heat insulating property of the inner layer 22 is improved, thereby increasing the service life of the soundproof door body 20.

[0042] Furthermore, both the thermal insulation layer 34 and the flame-retardant layer 32 are provided with outwardly protruding stoppers 35. The outer frame 21 is provided with stopper grooves corresponding to the stopper grooves 35. The stopper grooves 35 and the stopper grooves facilitate the installation between the outer frame 21 and the inner layer 22, simplifying the installation process and improving the efficiency of installing the soundproof door body 20.

[0043] Preferably, a concrete layer 40 is provided between the wall 10 and the soundproof door body 20. A plurality of sets of staggered reinforcing ribs 41 are provided in the concrete layer 40. The provision of the plurality of sets of reinforcing ribs 41 increases the bearing strength of the concrete layer 40, thereby increasing the overall strength of the concrete layer 40.
