Description

[Detailed description of the invention] This invention is a purge inlagrator that connects and accommodates a large number of purges and sails on the open ocean, so as to dissipate waves and swells so that they do not affect the purges stored inside. This invention relates to a wave dissipating device.

Conventionally, in purge inlagrators that house a large number of purges in an enclosure and sail on the open ocean, a large number of holes are installed at the bottom of the enclosure as a means of preventing waves and swells from affecting the inside of the enclosure. It is known that the wave-dissipating effect is achieved by installing a partition plate or arranging a wire mesh.

Such holes and wire mesh exhibit a wave-absorbing effect when the size of the holes and mesh matches the wave height and wavelength of the waves.

However, because wave heights and wavelengths change from moment to moment depending on the navigation area, weather conditions, etc., conventional perforated plates and wire mesh do not always have sufficient wave-absorbing effects. The influence of waves on the area has not been sufficiently eliminated.

For the purpose of this invention, a plurality of openings are provided in the partition plate at the bottom of the enclosure, a cylinder with both ends open is fixed to each of these openings, and the length of the cylinder is adjustable. To provide a wave dissipating device for a purge inlurator, which dissipates waves and undulations by making good use of the time lag when seawater passes through the cylinder, and prevents the influence of waves and swells from affecting the inside of an enclosure. It is in.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. The purge inragrator has a concave internal cut 1
A bow structure 1 having a diameter of A plurality of girders 6 are housed inside.

Note that the bottom has a double structure in which the first partition plate 5 and the second partition plate 21 are superimposed.

A gate 7 through which the purge 6 is taken in and taken out and a purge introduction path 8 are formed at the bowmost part of the bow structure 1.

The side girders 2 and 3 each have a tubular upper hollow beam member 9,
10, a lower hollow beam member 11.12 and a wave cutting plate connecting the two) 13.14, consisting of a wave cutting plate 13,
Inside the pipe fender 14, a plurality of reinforcing members 15 which also serve as pipe fenders are fixed at regular intervals in the length direction and in the vertical direction to reinforce the side girders 2 and 3.

Further above the upper hollow beam members 9 and 10, bulwarks 16 and 17 are provided to prevent waves and splashes.

A plurality of openings 18 are formed in the first partition plate 5 at the bottom, arranged at regular intervals, and each opening 18 has an inner diameter that is the same as the diameter of the opening 18 on the upper surface of the first partition plate 5. An inner cylindrical body 19 having both ends open is fixed.

Further, a second partition plate 21 is installed on the first partition plate 5 so as to be movable up and down.

A plurality of openings 22 approximately equal to the outer diameter of the inner cylindrical body 19 are formed in this second partition plate 21 and arranged at regular intervals. An outer cylindrical body 23 having the same inner diameter as the diameter of 22 and open at both ends is fixed.

The outer cylindrical body 23 and the inner cylindrical body 19 are fitted together so as to be vertically movable.

Note that the second partition plate 21 has an inner cylindrical body 19 and an outer cylindrical body 2.
After the length of the cylinder is adjusted by No. 3, it is fixed to the bottom by a fixing device (not shown).

In the case of a purge ingratator in which the internal size of the enclosure or the size of the first partition plate 5 is about 20 m in width and about 90 m in length, the diameter of the opening 1B and the inner cylindrical body 19 should be set to about 1. .5m, and the tube length is approximately 1m, and the width is approximately 5m.
It is preferable to form them at intervals of 7 to 8 m in the length direction.

A notch 4a is formed in the stern portion 4, into which a push boat 20 is inserted to push the purge inlagrator.

Also, a plurality of purges 6 housed inside the inflator
are connected to each other or to an inflator as required.

Vertical movement of seawater due to waves and swells is absorbed by the time lag of resistance and phase while it moves vertically inside the inner cylindrical body 19 and the outer cylindrical body 23, producing a wave-dissipating effect.

Therefore, the influence of waves and swells does not reach the inside of the enclosure, or the influence thereof can be reduced.

In addition, by adjusting the length of the inner cylindrical body 19 and the outer cylindrical body 23 according to the wave height and wavelength of waves and undulations, in addition to the wave absorption and wave dissipation effect provided by the cylinder, the wave height and wavelength Even if there is a difference in the grain size, it is possible to exhibit a wave-dissipating effect with finer grain, optimally, and long-grained.

According to the above-mentioned wave dissipating device in the purge inlulator of the present invention, the hull structure of the purge inlulator is surrounded by a surrounding wall body that accommodates a plurality of purges in a floating state without being pressed. The bottom of the enclosure has a double structure with a first partition plate and a second partition plate stacked on top of each other, and a plurality of vertically opening tubes are provided between these partition plates to prevent waves while sailing in the open ocean. It has a wave-dissipating effect against waves and swells, and prevents the effects of these waves and swells from reaching the inside of the enclosure.

In addition, as mentioned above, the length of these cylinders can be adjusted according to the wave height and wavelength, so even if there are differences in waves and swells,
Waves can be dissipated more effectively and optimally according to the difference. Therefore, the inside of the enclosure is always in a constant state of water, the purge is carried and navigated as one body without moving against the inlagrator, and the purge is mutually dissipated. The load and force acting on the connection part and the connection part between the purge and the inlagrator are significantly reduced, making navigation of the inlagrator and transportation of the purge safer.
