Specific embodiment
Below by attached drawing, the present invention is described in detail.
As shown in Figure 1, a kind of month pool choked flow wave absorption protective device, including buoyancy tank 1, intermediate structure 2, inlet opening 3；Injection
Mouth 4, buoyancy tank 1 are connected to form the protective device main structure by intermediate structure 2.The main structure by anchor chain 6 into
Row is fixed, and is equipped with multiple rows of aperture along the length direction of protective device in the intermediate structure 2, and intermediate structure aperture has formed the moon
Pond effect, the face of heading sea of the main structure is axially uniformly distributed equipped with multiple tubaeform inlet openings 3 along floating drum, described
Setting round jet port 4 corresponding with tubaeform inlet opening, the tubaeform inlet opening 3 and round injection above main structure
Mouth 4 is directly connected to, and structure can achieve the effect that good absorption incident flow in this.
Under wave and stream effect, water particle is entered by tubaeform inlet opening 3, is sprayed from round jet port 4.In two floating drums
Between 2 perforated area of main structure be gradually reduced along direction of heading sea, can absorb to greatest extent incidence wave wave and stream, avoid
Energy caused by because of wave loss is insufficient and caused by water body cannot rise to form moon pool effect.
Effect is flowed in order to increase to disappear, the present invention carries out to greatest extent as far as possible in abundant benefit using the area in face of heading sea
Opening, it is consistent with every row's square orifice the number of openings to form horn-shaped port, the corresponding arrangement in position.
For better effect, as shown in figure 4, each perforated area is gradually increased along the depth of water.Since moon pool effect makes
Water fierceness concussion in moon pool, facilitates wave absorption；Further, since moon pool effect, the liquid level in moon pool rises, and facilitates sea
Water passes through tubaeform water inlet.
For better effect, as illustrated in figs. 5-7, the lower section of each floating drum 1 disappears equipped with vane type flows device 10, institute
The vane type stated disappears, and to flow device 10 include that at least one set of vane type disappears drift net frame 11, every group of vane type disappear be equipped in drift net frame 11 it is more
A " X " type frame, the place intersected in each " X " type frame are equipped with axis 14, install blade 9 on the axis 14, when there is multiple groups blade
Formula disappear drift net frame 11 when, two-by-two vane type disappear drift net frame 11 pass through the first bolt 13 connect.
Every group of vane type, which disappears, is equipped with 10 " X " type frame in drift net frame 11, that is to say, that every group of vane type drift net frame 11 that disappears has
10 impellers.According to the actual situation, the drift net frame 11 that multiple groups vane type can be disappeared is combined.As shown in fig. 6, being two groups of multiple groups
Vane type disappears the combination of drift net frame 11.
U-shaped attachment device 12 is fixedly installed below each floating drum 1, the U-shaped attachment device 12 passes through third spiral shell
Bolt 15 and vane type, which disappear, to flow device 10 and is attached.
Vane type, which disappears, flows the rotation of blade 9 under the action of incoming flow of device 10, to consume the energy of stream.Simultaneously because the paddle
The rotation of leaf forms spiral flow after leading to blade, to further disturb the direction of stream, leads to incoming flow disorder, passes through both
Mode reaches good disappear and flows effect.
And such structure convenient disassembly, for ease of maintenaince.Overall structure is fixed using anchor chain 6, can be because of ground system
Preferably, can be with soil environmental background value, installation cost is lower.
Use is connected in order to multiple months pool choked flow wave absorption protective devices, the left and right of the main framework is equipped with
Main structure attachment device, the structure of the main structure attachment device be include two parallel profiles 16, described in two
Profile 16 connected with the second bolt 7, length is identical with the thickness of rubber ring 5 between two profiles 16.
As shown in figs. 10-12, the present invention also provides one kind, protect dress including multiple moon pool choked flow wave absorptions
It sets, each moon pool choked flow wave absorption protective device passes through anchor chain 6 respectively and is fixed, the pool of the moon two-by-two resistance
It flows and is connected between wave absorption protective device by rubber ring 5 and the second bolt 7, specifically: the rubber ring 5 is in parallel profile 16
The second adjacent bolt 7 is entangled in centre, and then the second bolt 7 is tightened.
Although the present invention has been described by way of example and in terms of the preferred embodiments, they be not it is for the purpose of limiting the invention, it is any ripe
This those skilled in the art is practised, without departing from the spirit and scope of the invention, can make various changes or retouch from working as, therefore guarantor of the invention
Shield range should be subject to what claims hereof protection scope was defined.
