[0021] The following will describe in detail the specific implementation of the present utility model in conjunction with specific embodiments.

[0022] Embodiment 1:

[0023] Please refer to Figure 1 , a sound insulation cover for an air source heat pump is provided, which includes a support base 11, a bearing base 12 arranged on the support base 11, and a noise reduction base 13 erected on the bearing base 12; a content hopper 14 is arranged on the noise reduction base 13, and a sound insulation cover hopper 15 is arranged on the content hopper 14; a support cylinder 21 is arranged on the side edge of the cover seat of the support base 11, a positioning pipe body 22 is arranged on the side edge of the support cylinder 21, and a pipe sleeve 23 installed on the positioning pipe body 22; the positioning pipe body 22 is installed on the side edge of the support cylinder 21 to provide an installation position for the pipe sleeve 23. The pipe sleeve 23 is used to pass through the intake and exhaust pipes of the heat pump or other necessary connecting pipelines, while maintaining the sealing and sound insulation of the pipelines.

[0024] In this embodiment, the support base 11 is made of strong steel or cast iron materials, with sufficient load-bearing capacity and stability. Anti-slip pads are provided at the bottom of the support base 11 to ensure the stability of the entire sound insulation cover on the ground. The bearing base 12 is arranged on the support base 11 and is made of lightweight and high-strength materials such as aluminum alloy or composite materials to reduce the overall weight while ensuring strength. The noise reduction base 13 is filled with high-efficiency sound insulation materials to effectively isolate the mechanical noise and air flow noise during the operation of the heat pump. The content hopper 14 is arranged on the noise reduction base 13, and its shape matches the outer shape of the heat pump unit to better wrap and isolate the noise source; the edge of the content hopper 14 is tightly connected to the noise reduction base 13 without gaps or sound leakage, and the sound insulation cover hopper 15 covers the content hopper 14 to form a complete sound insulation cover body. The sound insulation cover hopper 15 adopts a multi-layer structure design, including an outer support structure and an inner sound absorption material layer. Such a design can further isolate and absorb noise and improve the sound insulation effect.

[0025] This embodiment can protect the heat pump unit. At the same time, through the comprehensive application of multiple layers of sound insulation materials and structures, this sound insulation cover can significantly reduce the noise level during the operation of the air source heat pump, providing a quieter and more comfortable space for residents and the working environment.

[0026] Embodiment Two:

[0027] Please refer to Figure 2 , a channel-shaped sheet metal plate 31 is provided at the bottom of the bearing base 12. An installation base plate 32 is provided on the channel-shaped sheet metal plate 31. The noise reduction base 13 is mounted on the installation base plate 32. A support washer 33 is provided on the installation base plate 32, and a support carrier 34 is provided on the support washer 33. An absorption layer 35 is provided along the inner edge of the support carrier 34. A buffer bottom plate 36 is laid on the absorption layer 35. A bottom plate base surface 37 is padded on the bottom plane of the buffer bottom plate 36.

[0028] The channel-shaped sheet metal plate 31 is the main load-bearing structure of the sound insulation cover, enhancing the overall strength and rigidity of the base. It also improves the sound insulation performance through its unique channel structure, reducing the possibility of sound conduction through the base. Support washers 33 are evenly distributed on the installation base plate 32. The support carrier 34 and the absorption layer 35: The support carrier 34 is installed on the support washers 33, and a layer of absorption layer 35 is closely attached along its inner edge. The absorption layer 35 is made of high-performance sound absorption materials, such as porous fiber materials or open-cell foams, which can effectively absorb and convert noise energy, reducing noise reflection and transmission. Above the absorption layer 35, a layer of buffer bottom plate 36 is laid. This bottom plate is made of a lightweight and tough material, such as high-strength fiberboard or honeycomb structure board. The buffer bottom plate 36 not only provides stable support for the noise reduction base 13 but also further attenuates the vibration energy of sound through its internal structure.

[0029] Embodiment Three:

[0030] Please refer to Figure 3 , the sound insulation cover hopper 15 includes a closed collar 41 sleeved on the top of the inner hopper 14, and a rubberized raised hopper 42 provided on the closed collar 41. The rubberized raised hopper 42 has a convex structure and acoustic buffer heads 43 are provided on both sides thereof. Acoustic buffer protrusions 44 are provided on the acoustic buffer heads 43. The acoustic buffer protrusions 44 are elastically mounted on the acoustic buffer heads 43 and a buffer collar 45 for support is sleeved on the periphery of the acoustic buffer protrusions 44.

[0031] The sound insulation hood hopper 15 realizes seamless connection with the inner hopper 14 through the closing collar 41, ensuring the integrity of the sound insulation hood. The rubberized raised hopper 42 is made of a highly elastic rubber material, and its outer wall is provided with a shaping metal frame, having excellent sound insulation and shock absorption performance. Its unique convex structure design can effectively reflect and absorb the noise from the top, reducing the spread of noise. On both sides of the rubberized raised hopper 42, there is a sound wave buffer head 43 respectively. The sound wave buffer head 43 is filled with sound-absorbing material inside, which can further absorb and attenuate the noise. At the same time, on the sound wave buffer head 43, there is a sound wave buffer protrusion 44 elastically installed. These protrusion structures can undergo minute deformation when impacted by sound waves, thereby consuming sound energy, reducing the transmission of noise, and the buffer collar 45 plays a role of buffering and supporting at the same time.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms.
