Definitions

the present invention relates to a device for reducing the propagation of sound, vibrations and pressure surges in a liquid, in particular occurring when introducing an object into a background sound and / or in particular in water, with a plurality of gas-filled damping bodies and a carrier to the damping body can be arranged in a suitable relative position to each other.
a device of the type mentioned is, for example, from the WO 2009/121336 A2 known.
the known device has a plurality of damping bodies which can be filled with a gas and which are fastened to a carrier.
the carrier and the damping body are made in one piece from a thin, elastic tubing, wherein the damping body are delimited from each other by constrictions or welding webs of the tubing.
the damping body can be fixed by means of the carrier in a cage.
the present invention is therefore based on the object, a device of the type mentioned in such a way and further, that a safe operation of the device with structurally simple means is possible.
the above object is achieved by a device having the features of claim 1. Thereafter, the device is configured and further developed such that the carrier has a frame with horizontal linkage elements.
a one-piece structure of the carrier and the damping body made of a hose material is extremely unfavorable, especially in the case of a required replacement of the damping body or in the event of repair.
the design of the carrier with a frame having horizontal linkage elements solves the above problem in a surprisingly simple manner. Specifically, it is now possible to arrange the damping body in a suitable relative position to each other on the horizontal linkage element. Upon the occurrence of a defect or a leak of a single damping body, it is now sufficient to decouple the individual damping body of the rod element and attach an intact damping body as an exchange to the linkage element.
the defective damping body can also be removed for quick repair and attached to the linkage element again after the repair.
the problem of a possibly irreparable damping body with the result of a permanent functional impairment - as in the known carrier of tubing and the damping bodies formed thereon - no longer exists in the inventive device.
the frame could have a plurality of vertical and horizontal linkage elements arranged perpendicular to one another.
the frame could have a kind of lattice structure consisting of mutually vertically arranged linkage elements.
the device could be arranged in such a way around an object to be introduced into a ground that the vertical linkage elements could run substantially parallel to, for example, a pile or nail to be introduced.
the term horizontal or vertical ultimately refers to an orientation relative to the ground or water bottom, both of which each extend substantially in a horizontal plane.
the frame could be formed for example of metal.
steel or stainless steel could be used here as metal.
An embodiment made of plastic, in particular fiber-reinforced plastic, would be conceivable with regard to easier handling of the device for weight reasons, in particular during transport.
the frame could comprise a plurality of frame sections constructed from horizontal linkage elements which are coupled to one another via cables.
the different frame regions constructed from horizontal linkage elements could be positioned at different depths in the liquid, as it were.
the coupling of these frame areas is then via ropes, which replace the quasi existing in the previously described embodiment, vertical linkage elements.
the connection The frame areas on the ropes thus holds the entire device together and allows a particularly space-saving storage or a space-saving transport of the device when it is not in use.
the frame sections could be positioned close to each other with rolled up or otherwise taken together ropes to achieve the space saving effect.
this embodiment of the device also allows a saving of material, since usually less material is required for the provision of the cables than for vertical linkage elements.
damping body could be vented and / or arranged one above the other.
a kind of folding of the device could be achieved with this illustrated embodiment.
a top frame area could be designed as a floating body, which could be positioned on the surface or in the region of the surface of the liquid when the device is in use.
the remaining frame areas could be designed so that they do not experience buoyancy.
winches for the ropes could be assigned to this uppermost frame area.
the winches could be hydraulic winches.
the winches could be fixedly coupled to the uppermost frame area.
the frame could have a plurality of pivotable about at least one pivot axis frame parts or linkage elements.
a plurality of linkage elements could form such a pivotable frame part or it could also be realized between each linkage elements pivot axes, which allow angular positioning of the linkage elements relative to each other.
the frame parts or linkage elements could be pivoted to each other such that a cylinder jacket-like frame with a substantially closed shell can be generated.
a jacket could, for example, securely enclose a pile to be buried in a subsurface during ramming in such a way that a maximum of attenuation effect with regard to the propagation of the sound can be achieved.
the cylinder jacket-like frame could enclose a pole or other object as a cylinder jacket with a number of frame parts or linkage elements of polygonal base area corresponding to the number of frame parts.
the frame parts or linkage elements could be pivotable relative to each other such that a substantially hood-shaped frame can be generated.
a nail to be introduced into a substrate could be substantially enclosed by means of such a hood-shaped frame from above and laterally.
Such a mountable on a nail hood could have a passage for an acting on the nail impact tool.
the damping body could be releasably attached to the foundation body and also after the pounding from the top triggered float up for reuse before diving.
the frame could be assigned a pressure line for the introduction of the gas into the damping body.
each damper body could be fluidly connected to the pressure line.
a respective separate flow connection or flow line or pressure line from a pressure source to each individual damping body would be conceivable and could allow a particularly individual pressurization of the damping body.
the pressure line or the pressure lines could or could in principle be guided along the frame and attached to the outside of the frame.
the pressure line or the pressure lines could be integrated into the frame or arranged in the linkage elements. Damage to the pressure lines from the outside could thereby be safely avoided.
the damping bodies preferably depending on their depth position in the liquid-could be subjected to different gas pressure. This could ensure that the damping body always occupy an equal volume in the liquid regardless of a present deep external pressure.
damping body of the pressure line could be associated with a pressure control device and / or at least one pressure reducer.
a pressure control device and / or at least one pressure reducer.
damping bodies positioned at the same depth could be subjected to the same pressure.
Lower positioned damping bodies could be subjected to a higher pressure in order to counteract the increasing external pressure with increasing depth.
the damping body could have a sound-insulating open or closed-pore material in its interior, preferably on its inner wall.
a material could be foam, which is particularly effective especially in open-pore configuration.
open-pore foam or an open-pored material usually relaxes.
damping body could be used in a particularly advantageous and practical way so-called lifting bags with, for example, a surface area of 1 to 1.5m 2 .
lifting bags are particularly easy to handle especially because of their size.
these are flat damping bodies which are inflated by the introduction of the gas and thus unfoldable when not filled with gas.
damping bodies could have a soft rubber enveloping medium with a reinforcement, preferably an aramid cord liner. This results in a high level of robustness against external damage and corrosion. Furthermore are So-called lifting bags usually up to 8 bar pressure resistant and thus to at least 70 meters depth in a liquid, such as water, can be used.
the damping body could have at least one eyelet for attachment to the frame, on a frame part or on a linkage element.
the ease of mounting also results in a simple interchangeability in case of damage.
the damper bodies attached to the frame are oriented upwards in the liquid or in the water even without filled gas due to the buoyancy effect.
the damping bodies or lifting cushions can be fastened to the frame in such a way that the entire device allows a flow of the fluid through, so that little lateral force is exerted by the flow on the device when installing the device. This facilitates the installation of the device in the field of use.
the damping body can be filled with the gas or supplied with compressed air.
Fig. 1 shows a perspective view of an embodiment of an apparatus for reducing the propagation of sound in a liquid.
the device is used when introducing an object 1 into a substrate.
the object 1 is formed in this embodiment by a pile, which is to be introduced into the subsurface of a body of water.
the device has a plurality of damping body 2, which can be filled with a gas, and a carrier 3, on which the damping bodies 2 are arranged in a suitable relative position relative to one another.
the carrier 3 has a frame 4 with horizontal linkage elements 5. At this linkage elements 5, the damping body 2 are attached.
the damping body 2 are according to Fig. 1 arranged around the object 1 such that the object 1 is substantially completely enclosed.
the damping body 2 overlap slightly or in a suitable manner.
the frame 4 has in view of a particularly high stability and thus with regard to a particularly safe operation a plurality of mutually perpendicular vertical linkage elements 6 and horizontal linkage elements 5.
the closed state can be spent in an open state of the device.
the frame 4 a plurality of pivot axes 7, so that individual frame parts 8 can be pivoted against each other.
Fig. 2 and 3 show in a partial and enlarged side view of the embodiment Fig. 1 ,
Fig. 2 are designed as a cushion damping body 2 is not yet filled with gas.
the damping body 2 are already arranged substantially in its use position in the state not filled with gas, since the buoyancy prevailing under water pushes the damping body 2 fastened to the horizontal linkage elements 5 upwards.
Fig. 3 shows the same situation with damping bodies 2, which are filled with gas.
the Fig. 4 and 5 schematically show the embodiment Fig. 1 , where in Fig. 4 the above mentioned open and in Fig. 5 the above-mentioned closed state of the device are shown.
the frame 4 has a plurality about pivot axes 7 to each other pivotable frame parts 8.
the frame parts 8 are pivotable relative to one another such that a cylinder jacket-like frame 4 can be produced with a substantially closed jacket, as described in US Pat Fig. 5 is shown.
an object 1 such as a pile can be completely enclosed by the device during a driving into a ground in a simple manner, so that a reliable reduction of the propagation of sound generated during the driving process can be achieved.
the vertical linkage elements 6 can be replaced by ropes, so that the device is ultimately made up of a plurality of ring-like frame parts 8, which via the ropes with each other are coupled. In this case, a particularly space-saving storage of the device outside its use is possible.
