Description

Technical Field

[0001] This utility model relates to the field of ship bottom structure, and further to the ship bottom structure in which sonar detection equipment is embedded. Background Technology

[0002] Ships have been developed alongside human progress, existing in both times of war and peace. For example, millions of fishermen worldwide use fishing boats to catch fish; wartime naval battles and maritime military supply ships serve as logistical support vessels; and ships also play a vital role in geographical exploration and the development of science and technology.

[0003] For special tasks such as marine hydrology, geology, meteorology, and biology, scientific research vessels are generally used. In order to achieve their research objectives, scientific research vessels need to be equipped with various types of sensors on their hulls. Among them, sonar detection equipment is installed on the bottom of the hull for underwater target detection, classification, location and tracking, as well as underwater communication and navigation. However, the fairings installed on the outside of the sonar detection equipment protrude from the outer surface of the bottom plate, which increases the ship's drag. Utility Model Content

[0004] The purpose of this utility model is to provide a ship bottom structure for embedding sonar detection equipment, which solves the technical problem in the prior art where the hull plate protrudes outward at the location where the sonar detection equipment is installed, causing an increase in ship resistance. This allows the sonar detection equipment to be embedded in the hull while the ship resistance remains unchanged.

[0005] To achieve the above objectives, this utility model provides a ship bottom structure for embedding a sonar detection device, comprising: a hull, the hull including a bottom outer plate, the bottom outer plate including a plate body, the plate body having a recessed groove at the position corresponding to the sonar detection device facing inward toward the hull, the sound-transparent plate of the sonar detection device being connected to the opening of the recessed groove, the main body of the sonar detection device being located within the receiving space formed by the recessed groove and the sound-transparent plate, and the outer surface of the sound-transparent plate being flush with the outer surface of the bottom outer plate.

[0006] In some embodiments, the hull structure for embedding sonar detection equipment also includes an inner keel, which is laid continuously along the longitudinal direction of the hull on the inner surface of the outer hull plate.

[0007] In some embodiments, along the longitudinal direction of the hull, the inner keel includes a first straight plate portion, a first inclined straight plate portion, a second straight plate portion, a second inclined straight plate portion, and a third straight plate portion connected in sequence. The first inclined straight plate portion and the second inclined straight plate portion are symmetrically arranged on both sides of the second straight plate portion, and along the direction away from the second straight plate portion, the first inclined straight plate portion and the second inclined straight plate portion gradually move away from the interior of the hull.

[0008] In some embodiments, the hull structure for embedding sonar detection equipment also includes several transverse ribs, which are evenly arranged along the longitudinal direction of the hull on the inner surface of the outer hull plate and are perpendicularly connected to the inner keel.

[0009] In some embodiments, the distance between adjacent transverse ribs is the rib spacing, and along the longitudinal direction of the hull, the lengths of the first and second inclined straight plates along the longitudinal direction of the hull are multiples of the rib spacing.

[0010] In some embodiments, the lengths of the first and second inclined straight plates along the longitudinal direction of the hull are at least twice the rib spacing.

[0011] In some embodiments, the hull structure for embedding sonar detection equipment also includes at least one pair of side inner keels, which are laid continuously along the longitudinal direction of the hull on the inner surface of the outer hull plate, and each pair of side inner keels is symmetrically located on both sides of the central inner keel.

[0012] In some embodiments, the recessed groove transitions to the plate body via a circular arc.

[0013] In some embodiments, the recessed groove is detachably connected to the acoustically permeable plate.

[0014] In some embodiments, a flange is provided at the opening of the recessed groove, and the sound-permeable plate is detachably connected to the flange at the recessed groove by a bolt assembly.

[0015] Compared with the prior art, the ship bottom structure for embedding sonar detection equipment provided by this utility model has the following beneficial effects:

[0016] 1. The ship bottom structure for embedding sonar detection equipment provided by this utility model forms a main body for accommodating sonar detection equipment by recessing the outer plate of the ship bottom. Then, by keeping the sound-transparent plate of the sonar detection equipment flush with the plate body of the outer plate of the ship bottom, there will be no extra protruding part at the bottom of the ship, thereby ensuring that the ship's resistance remains unchanged and will not affect the navigation efficiency and fuel consumption.

[0017] 2. The ship bottom structure for embedding sonar detection equipment provided by this utility model is continuously laid on the outer plate of the ship bottom by the inner keel and the side keel. Compared with the existing technology, which has openings or discontinuous inner keels to avoid sonar detection equipment, the inner keel and the side keel can ensure the overall longitudinal strength without changing the height of the inner keel and the side keel.

[0028] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] In one embodiment, Figure 2 and Figure 3 As shown, this embodiment discloses a specific implementation of a ship bottom structure for embedding a sonar detection device 20. The ship hull 10 includes a ship bottom outer plate, which includes a plate body 11. The plate body 11 is recessed towards the inside of the ship hull 10 at the position corresponding to the sonar detection device 20 to form a recessed groove 12. The sound-transparent plate 21 of the sonar detection device 20 is connected to the groove opening of the recessed groove 12. The main body 22 of the sonar detection device is located in the receiving space formed by the recessed groove 12 and the sound-transparent plate 21. The outer surface of the sound-transparent plate 21 is flush with the outer surface of the ship bottom outer plate.

[0030] In this embodiment, the sound-permeable plate 21 is a non-metallic plate. Since the outer surface of the sound-permeable plate 21 is flush with the outer surface of the ship bottom plate, even if the sonar detection device 20 is installed at the bottom of the hull 10, the smoothness of the ship bottom can still be guaranteed, so that the ship's resistance will not increase and the navigation efficiency and fuel consumption will not be affected.

[0031] In one embodiment, Figure 3 As shown, the bottom structure of the ship with the sonar detection equipment 20 embedded also includes an inner keel 50 set on the central longitudinal axis 30. The inner keel 50 is laid continuously along the longitudinal direction of the hull 10 on the inner surface of the outer bottom plate.

[0032] In existing technologies, such as Figure 1 As shown, an opening 40 is made in the inner keel 50 to allow passage of the sonar detection device 20 located at the bottom of the hull 10, resulting in a reduction in overall longitudinal strength. Alternatively, in existing technologies, the inner keel 50 is also broken at the sonar detection device 20, which also reduces overall longitudinal strength. To solve the problem of reduced overall longitudinal strength in the existing technologies, the height of the inner keel 50 needs to be increased, which would occupy usable space within the hull 10. In this embodiment, since the inner keel 50 is laid continuously, the overall longitudinal strength of the ship can be maintained without increasing the height of the inner keel 50.

[0033] In one embodiment, Figure 3 As shown, the inner keel 50 includes a first straight plate portion 51, a first inclined straight plate portion 52, a second straight plate portion 53, a second inclined straight plate portion 54, and a third straight plate portion 55 connected in sequence. The first inclined straight plate portion 52 and the second inclined straight plate portion 54 are symmetrically arranged on both sides of the second straight plate portion 53, and along the direction away from the second straight plate portion 53, the first inclined straight plate portion 52 and the second inclined straight plate portion 54 gradually move away from the interior of the hull 10. The symmetrical arrangement of the first inclined straight plate portion 52 and the second inclined straight plate portion 54 ensures uniform stress distribution on the inner keel 50 and extends its service life.

[0034] In one embodiment, to enhance the structural strength of the hull bottom, the hull bottom structure in which the sonar detection device 20 is embedded further includes several transverse ribs. These transverse ribs are evenly arranged along the longitudinal direction of the hull 10 on the inner surface of the outer hull bottom plate and are perpendicularly connected to the inner keel 50. In this embodiment, the transverse ribs refer to ribs or ribs that are laid transversely on the outer hull bottom plate.

[0035] In one embodiment, the distance between adjacent transverse ribs is the rib spacing. Along the longitudinal direction of the hull 10, the lengths of the first oblique straight plate portion 52 and the second oblique straight plate portion 54 along the longitudinal direction of the hull 10 are multiples of the rib spacing, so that the transverse ribs are connected to the two ends of the first oblique straight plate portion 52 and the second oblique straight plate portion 54, making the connection between the two more convenient.

[0036] Furthermore, the lengths of the first inclined straight plate portion 52 and the second inclined straight plate portion 54 along the longitudinal direction of the hull 10 are at least twice the rib spacing. In this embodiment, the lengths of the first inclined straight plate portion 52 and the second inclined straight plate portion 54 along the longitudinal direction of the hull 10 are twice the rib spacing, thereby ensuring a relatively gentle transition between the first inclined straight plate portion 52 and the second inclined straight plate portion 54, reducing stress concentration at the connection points of the first straight plate portion 51 and the first inclined straight plate portion 52, the second straight plate portion 53 and the first inclined straight plate portion 52, the second straight plate portion 53 and the second inclined straight plate portion 54, and the second inclined straight plate portion 54 and the third straight plate portion 55. Of course, it is also possible for the lengths of the first inclined straight plate portion 52 and the second inclined straight plate portion 54 along the longitudinal direction of the hull 10 to be three times or more the rib spacing, depending on the actual design.

[0037] In one embodiment, the recessed groove 12 and the plate body 11 are connected by a circular arc, thereby eliminating the stress at the connection between the recessed groove 12 and the plate body 11 and improving the structural reliability.

[0038] In one embodiment, the hull structure in which the sonar detection device 20 is embedded also includes at least one pair of side inner keels, which are laid continuously along the longitudinal direction of the hull 10 on the inner surface of the outer hull plate and each pair of side inner keels is symmetrically located on both sides of the central inner keel 50.

[0039] In this embodiment, there is a pair of side inner keels, with the two side inner keels respectively set on both sides of the middle inner keel 50. When the sonar detection device is large, the recessed groove 12 will extend to the side inner keel. At this time, the side inner keel and the aforementioned middle inner keel 50 are laid continuously and form a bent shape, thereby achieving the same effect.

[0040] Of course, in other embodiments, if the sonar detection equipment is set at the side inner keel and does not extend to the middle inner keel 50, then only the side inner keel needs to be set in this way; the side inner keel can also be two pairs, three pairs or even more, depending on the actual situation, which will not be elaborated here.

[0041] In one embodiment, the recessed groove 12 is detachably connected to the acoustic plate 21. Specifically, a flange is provided at the opening of the recessed groove 12, and the acoustic plate 21 is detachably connected to the flange at the recessed groove 12 via a bolt assembly. Thus, when the sonar detection equipment needs to be replaced or repaired, the acoustic plate 21 can be quickly and without damage removed.

[0042] Of course, in other implementations, the detachable connection can also be a snap-fit ​​connection, etc., which will not be elaborated here.
