Abstract
The utility model relates to a marine geology investigation boats and ships moon pool structure belongs to marine geology investigation boats and ships field. The method is characterized in that: the moon pool opening is of a rectangular structure with the length of 3.6m by 3.5 m; the moon pool structure is made of high-strength steel; the moon pool structure adopts a double-layer structure, and the inner wall and the outer wall are connected by adopting a horizontal partition plate and a vertical partition plate; wave elimination holes are formed in the inner wall of the moon pool structure; the corner of the lower end opening of the moon pool is of a circular arc structure, and the radius of the circular arc is 300 mm. The wave sloshing phenomenon can be effectively reduced by changing the area ratio of the wave absorption holes of the moon pool on the inner wall; by changing the radius of the lower end opening of the moon pool at the corner, the ship resistance can be effectively reduced.
Description
Technical Field
The utility model relates to a moon pool structure of marine geology investigation boats and ships. Belongs to the technical field of marine geological survey ships.
Background
The new generation of marine geological survey vessels, due to the need for drilling exploration operations, typically have a moon pool running through the main hull in the midship for recovery of the equipment below or associated with the drilling equipment. The interior of the moon pool is communicated with seawater, and the fluid motion in the moon pool and the ship can generate coupling motion. On one hand, the moon pool has a large influence on the ship navigation resistance, and on the other hand, the seawater in the moon pool can generate a sloshing phenomenon. The utility model discloses moon pool structure reduces through the measure of addding the wave dissipation hole and rocks the phenomenon, through set up suitable being convex in order to reduce the ship resistance with moon pool lower extreme opening corner.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a marine geology investigation ship moon pool structure can reduce the moon pool to the resistance of boats and ships navigation, reduces the inside phenomenon of shaking of moon pool, can satisfy the operation demand of marine geology investigation ship.
In order to solve the above problem, the utility model discloses marine geology investigation boats and ships moon pool structure content includes:
the moon pool adopts a double-layer structure, and the inner wall and the outer wall are connected by adopting a horizontal partition plate and a vertical partition plate. A manhole is arranged on the clapboard and a wave-breaking hole is arranged on the inner wall of the moon pool so as to reduce attack generated by wave motion; the wave-eliminating holes are oval, and the total area of the wave-eliminating holes is 30-50% of the area of the inner wall of the moon pool structure;
the corner at the lower end of the moon pool is of a circular arc structure, the radius of the circular arc is 300mm, the navigation resistance is reduced, and the phenomenon of stress concentration in the end part area is avoided.

Detailed Description
In order to make the above objects and features of the present invention more comprehensible, the present invention will be described in further detail with reference to the accompanying drawings and embodiments.
As shown in fig. 1. The moon pool adopts a double-layer structure, and the inner wall 1 of the moon pool is connected with the outer wall 2 of the moon pool through a vertical partition plate 3.
As shown in fig. 2-3. Lightening holes 6 are formed in the horizontal partition plate 4 and wave-breaking holes 5 are formed in the inner wall 1 of the moon pool so as to reduce attack caused by wave motion; the wave-eliminating holes 5 are oval, and the total area of the wave-eliminating holes 5 is 30-50% of the area of the inner wall 1 of the moon pool structure.
As shown in fig. 4. The arc-shaped structure is arranged at the corner of the opening at the lower end of the moon pool, aiming at the opening and the ship-shaped characteristics of the moon pool with the diameter of 3.6 x 3.5m, and according to the actual test result, the arc radius 7 of R300mm is optimized, so that the better drag reduction effect relative to the right-angle corner and the arc corners with other radii is obtained, and the energy consumption required by ship navigation is saved.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
It will be apparent to those skilled in the art that various changes and modifications may be made in the invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
