Abstract
The invention relates to a collision-resistant prow structure of a public service vessel. The prow is a forerake snout prow. A reinforcing structure is fixedly arranged in the snout prow and comprises a longitudinal partition arranged in the central longitudinal position, a plurality of transverse partitions, a plurality of horizontal partitions and intermediate ribs, wherein the transverse partitions are welded on the longitudinal partition, and the horizontal partitions and the intermediate ribs are perpendicularly arranged at intervals. The longitudinal partition, the transverse partitions, the horizontal partitions and the intermediate ribs are welded with an outer board respectively. The collision-resistant prow structure takes the advantages of a conventional linear forerake prow of the public service vessel and adopts the forerake snout prow, the reinforcing structure of the prow is optimized by a finite element method, collision resistance of the prow of the public service vessel is improved and powerful guarantee is provided for effectively safeguarding marine rights and interests.
Description
Technical field
The present invention relates to a kind of bow construction, particularly relate to a kind of impact resistant bow construction of public affair ship.
Background technology
Marine Administrative Enforcement of Law is the important leverage safeguarding maritime rights and interests; due to the particularity of Maritime Law Enforcement and the reality of relevant public affair ship " unarmed " (or " light arm "); force target ship change flight path or lose ability to act by pushing or clashing into, become the Maritime Law Enforcement means of increased popularity in recent years.For marine complicated law-enforcing environment, need law enforcement public affair gear for crash-resistant bow construction.At present, public affair ship many employings straight line proclined bow, its advantage is that stem not easily goes up wave, floor space is large, tailored appearance, but due to the bow of this kind of form comparatively sharp thin, when colliding, stem deck affected area is comparatively large, is therefore unfavorable for that employing is pushed tactics and carried out marine right-safeguarding.
Summary of the invention
Technical matters to be solved by this invention is the impact resistant bow construction providing a kind of public affair ship, still can ensure that forecastle deck is not destroyed when bow is collided.
The technical scheme that the present invention solves the problem is as follows:
An impact resistant bow construction for public affair ship, is characterized in that:
Described bow is FC bulb bow, and described bulb bow inside sets firmly reinforcement structure,
Described reinforcement structure comprise be arranged in the fore and aft diaphragm of vertical position, the horizontal baffle that some lateral partitions be welded on fore and aft diaphragm, some vertical spacings are arranged and be arranged on the intermediate frame of the bulb bow first half, described fore and aft diaphragm, lateral partitions, horizontal baffle, intermediate frame respectively with outside plate weld together.
Further improvement is, described lateral partitions is arranged in bulb bow on every grade of rib position, and lateral partitions and outside plate adopt two-sided successive welding.
Further again, described horizontal baffle uniform intervals is arranged, and extend certain distance from bow to stern, the vertical distance of adjacent level dividing plate is less than 2m, and horizontal baffle and outside plate adopt two-sided successive welding.
Further, described intermediate frame is arranged on the first half of bulb bow, and intermediate frame is positioned at half grade of rib position place, is connected with bracket between the two ends of intermediate frame and horizontal baffle.
Preferably, described outer plate thickness is 14-18mm.
Preferably, the thickness of described lateral partitions and horizontal baffle is 10-14mm.
Preferably, described intermediate frame is band steel form, and thickness of slab is 14-18mm.
Reinforcement structure of the present invention adopts finite element method to promote bow collision resistance, described finite element method supposition bulb bow clashes into rigid walls, analogue computing is bow distortion when different velocity of impact, to assess bow collision resistance, instructs bow construction to carry out impact resistant reinforcement.
Compared with prior art, beneficial effect of the present invention is:
The present invention absorbs the advantage of straight line proclined bow, adopts FC bulb bow, and the reinforcement structure of bow adopts Finite Element Method to be optimized, and improves the bow collision resistance of public affair ship.Reinforcement structure of the present invention is applied on 4000 tons of public affair ships, when employing is at sea pushed or ramming tactics drives the external ship of illegal invasion, effectively can alleviate the destruction of ship collision to self stem deck on the one hand, ensure safety of ship, can improve on the other hand and law enforcement validity is driven to illegal invasion ship, crash-resistant bow construction is that marine right-safeguarding law enforcement employing is pushed tactics and provided strong guarantee, thus the marine right-safeguarding law enforcement of public affair ship can be improved and safeguard the ability of maritime rights and interests, for exercising marine site jurisdiction, Development of Marine economy provides guarantee.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail; the restriction of described embodiment not to invention protection domain; obviously, those of ordinary skill in the art are not needing to obtain other embodiments under the prerequisite paying creative work, and these all belong to protection scope of the present invention.
Shown in composition graphs 1 to Fig. 4, a kind of impact resistant bow construction of public affair ship, described bow is FC bulb bow, described bulb bow inside sets firmly reinforcement structure, described reinforcement structure comprise be arranged in the fore and aft diaphragm 4 of vertical position, some lateral partitions 5 be welded on fore and aft diaphragm, some vertical spacings arrange horizontal baffle 6 and intermediate frame 7, described fore and aft diaphragm, lateral partitions, horizontal baffle, intermediate frame respectively with outside plate 3 weld together.
Described lateral partitions is arranged in bulb bow on every grade of rib position, and lateral partitions and outside plate adopt two-sided successive welding.Lateral partitions, as the main support component in Bulb bows, bears impact load, and is delivered on fore and aft diaphragm and horizontal baffle.
Described horizontal baffle uniform intervals is arranged, and extend certain distance from bow to stern, the vertical distance of adjacent level dividing plate is less than 2m, and horizontal baffle and outside plate adopt two-sided successive welding.
Described intermediate frame arranges half grade of rib position place, is connected with bracket 9 between the two ends of intermediate frame and horizontal baffle.Intermediate frame is arranged on the first half of bulb bow, in order to reduce the outside plate panel of collision area.
In the present embodiment, the thickness of middle mediastinum plate, lateral partitions and horizontal baffle is not less than 0.5 times of outer plate thickness, and described outer plate thickness is preferably 14-18mm.The thickness of described lateral partitions and horizontal baffle is preferably 10-14mm.Described intermediate frame is band steel form, and thickness of slab is 14-18mm.
