Description
Technical Field
The application relates to the technical field of vibration isolation, in particular to a vibration isolation section and an underwater detection system.
Background
Data transmission between underwater detection devices (e.g., shore arrays, towed arrays, subsea topography imaging devices, cabled submarines, etc.) and above-water platforms (e.g., vessels, coastal platforms, offshore platforms) is required via streamers. On the one hand, the moving water platform of the ship and the like has strong mechanical noise due to the vibration of the water platform, and the mechanical noise can be transmitted to the detection equipment through the towing rope; on the other hand, when the towing rope shakes, vortex-induced vibration is generated by the relative motion of the water and the towing rope, and extra noise is caused, and the working performance of the detection equipment is seriously affected by the two. For this reason, it is often desirable to provide vibration isolation sections on the streamer to reduce the transmission of vibrations and noise, thereby reducing the effects of waterborne platform vibrations and streamer sloshing noise on the detection apparatus.
In the prior art, in order to improve the vibration isolation performance of the vibration isolation section, the length of the vibration isolation section is increased and/or a plurality of sets of rubber dampers are arranged. However, too long a vibration isolation section can reduce the quality of data transmission between the underwater detection device and the above-water platform; the arrangement of a plurality of groups of rubber vibration absorbers can increase the volume, the weight and the cost of the vibration isolation section, and the increase of the volume and the weight of the vibration isolation section increases the difficulty for the operations of storing, winding and unwinding, dragging and the like of the vibration isolation section. Accordingly, there is a need for other solutions to improve the vibration isolation performance of vibration isolation sections at low cost without increasing the length, volume and weight of the vibration isolation sections.
Disclosure of Invention
In view of the above, it is desirable to provide a vibration isolation section that achieves improved vibration isolation performance at low cost without increasing the length, volume, and weight of the vibration isolation section.
In order to solve the problems, the application provides the following technical scheme:

Both factors improve the vibration isolation performance of the vibration isolation section.

Referring to fig. 1 to 3, the present application provides a vibration isolation section, which includes a front end connector 1, a rear end connector 2, a data transmission line 3, a vibration isolation member 4, and a sheath 5. The rear end connector 2 and the front end connector 1 are sequentially arranged at intervals along the first direction. Both ends of the data transmission line 3, both ends of the vibration isolation member 4 and both ends of the sheath 5 are fixedly connected to the front end connecting member 1 and the rear end connecting member 2 respectively, and the sheath 5 is sleeved outside the data transmission line 3 and the vibration isolation member 4. At least part of the sheath 5 and at least part of the vibration insulating member 4 are each of an elastic structure so that the sheath 5 and the vibration insulating member 4 can be stretched together in the first direction. Wherein, front end connector 1 and rear end connector 2 are used for connecting different objects (such as underwater detection equipment and water platform), data transmission line 3 can transmit data between the object that front end connector 1 connects and the object that rear end connector 2 connects, vibration isolation 4 is used for the vibration isolation, sheath 5 is used for protecting data transmission line 3 and vibration isolation 4, and the first direction is the left and right directions in fig. 1.
In the vibration isolation section of the prior art, the sheath 5, after being connected with the connecting pieces at the two ends, encloses a closed space together with the connecting pieces at the two ends, and the vibration isolation piece 4 is located in the closed space. In the stretching process of the vibration isolation section, negative pressure can be formed in the closed space, and the negative pressure can obstruct the stretching of the vibration isolation section so as to reduce the vibration isolation performance of the vibration isolation section. Referring to fig. 1 and 2, in the vibration isolation section provided by the present application, the sheath 5 is the outermost structure of the vibration isolation section. Referring to fig. 3, a passage 51 is provided in the wall of the sheath 5, and the passage 51 communicates the space in the sheath 5 in which the vibration insulating member 4 is accommodated with the outside. Therefore, the space in the vibration isolation section is an open space communicated with the outside, and negative pressure which prevents the vibration isolation section from stretching can not be formed in the vibration isolation section in the stretching process of the vibration isolation section, so that the vibration isolation performance of the vibration isolation section is improved. Providing the passage 51 in the wall of the sheath 5 does not increase the length, volume and weight of the vibration isolation section and is low cost. Therefore, the present application achieves low cost improvement of vibration isolation performance of the vibration isolation section without increasing the length, volume and weight of the vibration isolation section.
Moreover, the passage 51 allows water to enter and exit the vibration isolation section. On one hand, the interaction between the water entering the vibration isolation section and the internal structural surface of the vibration isolation section can increase the damping of the vibration isolation section; on the other hand, after water enters the vibration isolation section, the distribution condition of the force in the vibration isolation section can be improved, local stress concentration can be avoided, and the efficiency of vibration transmission in the vibration isolation section is reduced. Both factors improve the vibration isolation performance of the vibration isolation section. In addition, during the expansion and contraction of the vibration isolation section, water enters and exits the vibration isolation section to take away heat generated during the operation of the vibration isolation section, so the heat dissipation performance of the vibration isolation section is improved due to the arrangement of the channel 51.
Referring to fig. 4, in some embodiments, the sheath 5 is a helical structure made of a metal/metal alloy, and the gaps between turns of the sheath 5 form channels 51. Firstly, this allows the sheathing 5 to have a certain vibration isolation performance and vibration damping performance, and can improve the vibration isolation performance of the vibration isolation section. Secondly, this makes the passage 51 also spiral, and water can be uniformly introduced into and discharged from the vibration isolation section in the length direction of the vibration isolation section, which is advantageous in improving vibration isolation performance and heat dissipation performance of the vibration isolation section. Finally, the sheath 5 has a certain rigidity, so that when the sheath 5 is bent, stretched, twisted, wound and the like, the cross section of the sheath 5 is always round or nearly round, therefore, the sheath 5 can play a role in radial support, and the data transmission line 3 and the vibration isolation member 4 in the sheath 5 can be prevented from being extruded in the process of bending, stretching, twisting, winding and the like of the vibration isolation section. Illustratively, the sheath 5 is made of stainless steel/titanium/nickel/titanium alloy/nickel alloy.
Preferably, referring to fig. 4, the sheath 5 is spirally wound from a metal/metal alloy member having a rectangular cross section. On the one hand, this can enhance the ability of the sheath 5 to absorb and attenuate vibration energy, thereby enhancing the vibration isolation properties of the vibration isolation section. On the other hand, this can appropriately improve the rigidity of the sheath 5, can improve the radial shape-retaining effect provided by the sheath 5 when bending, stretching, twisting, winding or the like occurs in the vibration isolation section, and can improve the protection effect of the sheath 5 on the data transmission line 3 and the vibration isolation member 4 in the sheath 5. Illustratively, the sheath 5 is helically wound from stainless steel/titanium/nickel alloy strips.
Referring to fig. 5, in other embodiments, the sheath 5 is a tubular structure made of a soft viscoelastic material, and the wall of the sheath 5 is provided with a through hole, and the through hole forms a channel 51. Soft viscoelastic materials have internal dissipation characteristics that, when they deform, can convert some of the mechanical vibrational energy into thermal energy, thereby reducing the energy of the vibration. This property of the soft viscoelastic material enables the sheath 5 to effectively absorb and attenuate vibration energy, thereby enhancing the vibration isolation properties of the vibration isolation section. The sheath 5 is illustratively a tubular structure made of polyurethane/neoprene.
Preferably, the sheath 5 is made of a soft viscoelastic material with a larger shear wave attenuation factor, which can further improve the absorption and attenuation capacity of the sheath 5 to flow noise during underwater towing operation, thereby improving the vibration isolation performance of the vibration isolation section.
Referring to fig. 5, in some embodiments, the wall of the sheath 5 is uniformly provided with a plurality of through holes. Therefore, water can uniformly enter and exit the vibration isolation section, and the vibration isolation performance and the heat dissipation performance of the vibration isolation section are improved.
In order to improve the protection degree of the data transmission line 3 and the vibration isolator 4 by the sheath 5, the size of the channel 51 is small. Specifically, in the embodiment shown in fig. 4, the spacing between two turns of the sheath 5 is small; in the embodiment shown in fig. 5, the through holes on the sheath 5 are circular holes, and the diameters of the through holes are smaller.
