Technical Field

Background

In the fields of construction, ships, vehicles and the like, a large number of pipeline systems are required, and due to the complexity of the pipeline systems, pipelines pass through the wall plates of the structural cabin inevitably, and in order to maintain the tightness of the cabin wall and the maintainability of the pipelines, cabin penetrating pipe fittings are required to be connected with the wall plates integrally, and the cabin penetrating pieces are adopted to rigidly and fixedly connect the outer walls of the pipelines with the wall plates, so that the cabin penetrating pieces only play a role in supporting and fixing the pipelines. When the pipeline is transmitting high pressure or pulsating fluid, the strong vibration of the pipeline is caused by the excitation action of the fluid, and the vibration is inevitably transmitted to the bulkhead through the cabin penetrating member, so that the secondary structural vibration and structural radiation noise of the wallboard are caused.

In order to isolate vibration, a flexible vibration isolation material is usually added between the pipeline and the wallboard, but the dynamic load of the pulsation of the pipeline is usually smaller than the static load of the fluid and the self weight of the pipeline, and the rigidity of the vibration isolator cannot be too small in order to keep the stability of the deformation of the pipeline under the static load state. And the vibration isolation effect of the vibration isolator is directly related to the rigidity, and the larger the rigidity is, the poorer the vibration isolation effect is. Therefore, the vibration isolation effect of the vibration isolator is often in contradictory relation to the stability of the apparatus. The ideal vibration isolator needs to meet the characteristics of high rigidity in a static state and low dynamic rigidity under the action of dynamic load. For example, chinese patent publication No. CN115076467a provides a cabin penetrating device and a ship, the cabin penetrating device includes: the device comprises a cabin penetrating pipeline, a first bushing, an elastic piece and a vibration reduction assembly; the first bushing is sleeved on the cabin penetrating pipeline, and a containing space is formed between the first bushing and the cabin penetrating pipeline; the two ends of the elastic piece are respectively connected with the cabin penetrating pipeline and the first bushing, and the elastic piece is used for providing vibration damping acting force along the radial direction of the cabin penetrating pipeline; the vibration damping assembly is arranged in the accommodating space, two sides of the vibration damping assembly are respectively connected with the outer wall surface of the cabin penetrating pipeline and the inner wall surface of the first bushing, and the vibration damping assembly is used for providing vibration damping acting force along the axial direction of the cabin penetrating pipeline. The vibration problem between the cabin penetrating piece and the wallboard is solved through setting up first bush, elastic component and damping subassembly to above-mentioned patent to, have certain rigidity, realized ideal vibration isolation effect. However, the device has a complex structure, and is not easy to install, maintain and the like. The rigidity of the device can not be regulated according to specific conditions, the vibration reduction assembly is realized by the interaction of two magnets, and the cost is high.
