Embodiment Construction

[0022] The following examples describe the present invention in more detail.

[0023] combine figure 1 , a dock for measuring underwater radiated noise of ships includes: a double-layer concave dock shell 1 and a dock door 2 .

[0024] combine figure 2 , the double-layered dock shell is a box structure with a concave cross-section, the base of the double-layered dock shell enters the seabed, and the top is higher than the sea surface. Both the inner and outer dock shells are sound insulation boards 11, supported by bridge brackets 12, and the air layer 13 is between the double dock shells.

[0025] The bridge support in the double-layer dock shell can be a support member such as I-beam or concrete pier. The bridge support is used to support the inner and outer dock shells, and has a bearing capacity in terms of building strength. The four corners of the double-deck dock shell are provided with bollards 14 .

[0026] The dock door is a skirt structure, which is a semi-cyli...

Abstract

The invention provides an offshore dock for measuring underwater radiated noise of ships. Including a dock shell and a dock door, the dock shell is a double-layer box structure with a concave cross-section, the dock shell base enters the seabed, the top is higher than the sea surface, and the inner and outer layers of the dock shell are sound insulation boards, inner and outer layers. between the inner and outer layers of the dock shell is an air layer, and the dock door is a semi-cylindrical guide opening extending inward from the middle of the fore and aft of the dock. The ship underwater radiated noise measurement dock designed by the invention from the perspective of acoustics fully considers the sound insulation performance and water flow diversion ability in structure, ensures the necessary rigidity and stability, and provides enough space for the normal operation of the ship, which is designed for the ship. , construction and navigation provides a large-scale test platform for acoustic diagnosis and evaluation.

Description

technical field [0001] The invention relates to an offshore dock, in particular to an offshore dock for measuring underwater radiated noise of ships. Background technique [0002] A dock is a dock-like structure for repairing and building ships, often found in shipyards or ship repair yards. The basic composition of a common dry dock includes three parts: the dock mouth, the dock chamber and the dock head. The design and construction are only considered in terms of structural scale and strength. Most of the building structures are excavated pools with reinforced concrete walls. Cubic shape, the cross-section is a concave structure, and there is an openable dock for ships to enter and exit the dock. This kind of dry dock is universal in structure, and there is no difference in design technology, but the scale and strength are different according to the needs of shipyard engineering, and in function, it is only used as a working place for ship construction and maintenance.
