Description

A kind of improved type fishing boat body

Technical field

The utility model relates to a kind of fishing boat, especially a kind of hull of fishing boat.

Background technology

Fishing boat, i.e. Fishery Vessel, carries out the fishing boat body of fishes fishing, processing, transport and is referred to as.Fishing vessel is made up of mass part, by the effect of each several part and purposes, can comprehensively be summarized as the three parts such as hull, marine powerplant, ship ' s equipment, and wherein hull is the essential part of boats and ships.

Traditional fishing boat body, as shown in Figure 1, its structure generally comprise hull 1 ' and for stablize the keel 2 of hull ', this keel 2 ' be arranged on hull 1 ' bottom, this keel 2 ' be along hull 1 ' the rectangle structure that extends of length direction, this hull 1 ' stern peripheral hardware be useful on be located at the ship honeycomb duct 3 of fishing boat screw propeller 100 ' outer ', this ship honeycomb duct 3 ' axial first end upper edge along being connected with hull 1 ' solid welding, lower edges and keel 2 ' end solid welding together with; This fishing boat body, because of keel 2 ' gravity be certain, and keel 2 ' structure is rectangle, non-polymorphic structure, this just make keel 2 ' height cannot be made into highlyer, generally seem lower, the keel 2 of low clearance ' can cause hull 1 ' with keel 2 ' supply ship honeycomb duct 3 ' installation site less, make ship honeycomb duct 3 ' bore can only adopt small-bore body, small-bore ship honeycomb duct 3 ' interior can only be installed its oar diameter and all less screw propeller of shp; But, diesel engine in marine powerplant is all to adopt high-performance diesel engine, so just there will be high-performance diesel engine for boats to drive the phenomenon of the screw propeller that shp is little, there is the phenomenon of " low load with strong power ", output mechanical power and the efficiency of diesel engine for boats all can not be fully used, cause huge energy dissipation, meanwhile, there is swing in straight keel can cause hull 1 ' travel time.There is the phenomenon of low load with strong power in order to solve diesel engine for boats, also there are some fishing boats that traditional undersized ship honeycomb duct and oar diameter, screw propeller that shp is less are replaced with to large-sized ship honeycomb duct and oar diameter, screw propeller that shp is larger, simultaneously, for the installation of this large-sized ship honeycomb duct can only by whole hull 1 ' the degree of depth deepen, the intensification of this hull 1 ' degree of depth has increased the cost of hull undoubtedly greatly, make hull 1 ' cost higher.

In view of this, the inventor conducts in-depth research the defect of fishing vessel hull, and this case produces thus.

Utility model content

The purpose of this utility model is to provide a kind of improved type fishing boat body, it can solve and be underutilized compared with the little output mechanical power that causes high-performance diesel engine for boats because of the shp of screw propeller, and then cause the problem of energy dissipation, can't increase the cost of hull, comparatively steady also can make hull travel time, difficult swing.

The technical solution of the utility model is such: a kind of improved type fishing boat body, comprise hull body, keel body and ship honeycomb duct, this keel body solid welding is on the bottom of hull body, and this keel body extends along the length direction of hull body, and this keel body is column structure, the above-mentioned keel body rectangular triangle in cross section along its length, and the inclined-plane of above-mentioned keel body is the bottom surface of above-mentioned keel body, the fore place of the small end of above-mentioned keel body in above-mentioned hull body, the stern place of the large end of above-mentioned keel body in above-mentioned hull body, above-mentioned ship honeycomb duct is arranged on the stern place of above-mentioned hull body, and above-mentioned ship honeycomb duct edge on the end, axial one end of hull body coordinates with the stern bottom solid welding of above-mentioned hull body, under this end end, edge extends to the large end bottom of above-mentioned keel body, and coordinate with the solid welding of keel body, and the large end place of above-mentioned keel body is provided with its first end in keel body, the second end stretches out this external supreme prop shaft of stating in ship honeycomb duct of keel, above-mentioned prop shaft is arranged on keel body in rotating mode.

The fore bottom place of above-mentioned hull body convexes with outwardly player.

Above-mentioned player's lateral surface is arc surface.

Adopt after such scheme, a kind of improved type fishing boat body of the present utility model, due to the rectangular triangle in keel body cross section along its length, and the stern place of the large end of keel body in hull body, like this, the height of the keel body that the height of the large end of the rectangular leg-of-mutton keel body in its cross section is rectangle much larger than its cross section under the keel body of identical weight, and prop shaft is arranged on the large end place of keel body, the position that keel body and hull supply ship honeycomb duct are installed is extended, thereby make fishing boat body of the present utility model can adopt the heavy caliber ship honeycomb duct of its bore much larger than traditional fishing boat ship honeycomb duct without the degree of depth of deepening hull body, the setting of heavy caliber ship honeycomb duct can make screw propeller can adopt large diameter blade and high-performance prop shaft, avoid traditional large-power marine diesel engines to drive the little screw propeller of shp and occurred the problem of low load with strong power, output mechanical power and the efficiency of high-performance diesel engine for boats can be fully used, can not cause the waste of the energy, comparatively energy-conservation, can't increase the cost of hull, and utilize the intensification of the large end of keel body place height can make the stern of hull comparatively steady, be difficult for occurring swing, the small end of keel body arranges the fore place of hull, make the draft at fore place of hull more shallow, be conducive to pulling in to shore of hull, again because the fore bottom place of hull body convexes with outwardly player, while hull body 1 being advanced by this player, can rive to the seawater heading on, thereby seawater head-on can not stopped by the hull when front, greatly improve the flow velocity that advances of fishing boat, reduce energy consumption, save the energy, also can improve the stable of hull body.
