Abstract
The utility model discloses a kind of small Fishing Boat cabins of band flexibility bulb bow, including hull and are arranged on the hull bottom and the flexible bulb bow near hatch door；The two sides fixing seal of the flexibility bulb bow is in the hull wall at the hatch door position, the top of the flexibility bulb bow is fixed on rigid support, the rigid support fixation is nested on the hydraulic push rod of the two-way hydraulic cylinder, and the two-way hydraulic cylinder is connected by liquid conduits with bidirectional hydraulic pump.The flexibility bulb bow can be used in lowsteaming, and when high speed operation is withdrawn, and play the effect of " resistance is reduced during low speed " of bulb bow structure in itself to the maximum extent；Flexible bulb bow can prevent head-on incoming from leading to the deformation of flexible bulb bow to the impact of flexible bulb bow by rigid carrier supports；Flexible bulb bow two sides are sealed with cabin edge, prevent the generation of the accident of hull leak and flexible bulb bow leakage.
Description
Technical field
The utility model belongs to technical field of ships, and in particular to a kind of small Fishing Boat cabin of band flexibility bulb bow.
Background technology
Bulb bow is a kind of damping device of the ship mainly for lowsteaming, when marine low speed is navigated by water, flexible ball
Nose bow can reduce wave making resistance, and bulb bow has the viscous pressure resistance that rectified action can reduce low speed ship.Bulb bow master
To be applied to hypertrophy low speed ship, processing technology is complicated, and cost is higher, and flexible ball is installed for small Fishing Boat
Nose bow, seldom installs bulb bow, because only that navigation when achieve the effect that design speed when can just generate it is positive, and drag reduction imitate
Fruit is best；Otherwise, bulb bow can bring the resistance of bigger to the navigation of ship instead.It is singly dragged so that fishery vessel type is more universal
For fishing boat：The time of one single trawler, one flight number is 15 days or so, and the production time is far more than the navigation in round-trip fishing ground
Time, it is assumed that the design speed of the ship bulb bow reaches maximum drag-reduction effect when being 8Kn-11Kn (speed of a ship or plane in round-trip fishing ground is 8Kn
More than, the speed of a ship or plane in production process is 2-3Kn), that is to say, that the drag reduction time, which is less than, increases the resistance time, then bulb bow is in trawler
The effect of drag-reduction energy-saving is not had in ship application, increases resistance energy consumption instead, additionally mounted bulb bow can increase cost.
Invention content
The purpose of this utility model is dropped aiming at the deficiency of above-mentioned technology when providing a kind of simple mounting structure, low speed
The small Fishing Boat cabin of the band flexibility bulb bow of lower resistance.
To achieve the above object, the small Fishing Boat cabin of the band flexibility bulb bow designed by the utility model, including ship
Body and it is arranged on the hull bottom and the flexible bulb bow near the hatch door；The two sides of the flexibility bulb bow are fixed close
It is enclosed in the hull wall at the hatch door position, the top of the flexibility bulb bow is fixed on rigid support, described firm
Property stent fixation be nested on the hydraulic push rod of the two-way hydraulic cylinder, the two-way hydraulic cylinder pass through liquid conduits with it is described double
It is connected to hydraulic pump.
Further, decompression compression bar and supercharging compression bar are respectively arranged on the bidirectional hydraulic pump.
Compared with prior art, the utility model has the following advantages：The bulb bow of the utility model can be in lowsteaming
When use, when high speed operation, is withdrawn, and plays the effect of " resistance is reduced during low speed " of bulb bow structure in itself to the maximum extent；It is soft
Property bulb bow can prevent head-on incoming from leading to the change of flexible bulb bow to the impact of flexible bulb bow by rigid carrier supports
Shape；Flexible bulb bow two sides are sealed with cabin edge, prevent the generation of the accident of hull leak and flexible bulb bow leakage.
Description of the drawings
Fig. 1 is the small Fishing Boat cabin structure schematic diagram of the utility model band flexibility bulb bow；
Fig. 2 is structure diagram after bulb bow flexible in Fig. 1 molding completely.
Each part numbers are as follows in figure：
Hull 1, flexible bulb bow 2, hull wall 3, bidirectional hydraulic pump 4, liquid conduits 5, supercharging compression bar 6, decompression compression bar 7,
Two-way hydraulic cylinder 8, hydraulic push rod 9, rigid support 10, top 11.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
The small Fishing Boat cabin of band flexibility bulb bow as shown in Figure 1, including hull 1 and be arranged on 1 bottom of hull and
Flexible bulb bow 2 near hatch door.In the present embodiment, the two sides fixing seal of flexible bulb bow 2 is positioned at hatch door position
It puts in the hull wall 3 at place, the top 11 of flexible bulb bow 2 is fixed on rigid support 10, and the fixation of rigid support 10 is nested with
On the hydraulic push rod 9 of two-way hydraulic cylinder 8, two-way hydraulic cylinder 8 is connected by liquid conduits 5 with bidirectional hydraulic pump 4, bidirectional hydraulic pump
Decompression compression bar 7 and supercharging compression bar 6 are respectively arranged on 4.
When small Fishing Boat is run at high speed, hatch door is closed as shown in Figure 1, flexible bulb bow 2 is located in cabin 1；When medium and small
When type fishing boat is run at a low speed, hatch door is opened, and flexible 2 two sides of bulb bow and 3 contact position of hull wall at hatch door position are close
Envelope；When small Fishing Boat speed slows down, flexible bulb bow 2 is gradually stretched out by cabin, hair by the hydraulic push rod 9 of two-way hydraulic cylinder 8
Wave drag reduction effect.
Detailed process is：Supercharging compression bar 6 is pulled back and forth, bidirectional hydraulic pump 4 is made to pressurize into two-way hydraulic cylinder 8, hydraulic thrust
Bar 9 gradually extends, and the flexible bulb bow 2 on rigid support 10 is driven gradually to stretch out cabin, until stopping when elongation is to maximum length
It only extends, flexible bulb bow 2 is molded at this time, as shown in Fig. 2, playing it completely subtracts rent effect.When small Fishing Boat again speeds up,
It when flexible bulb bow plays the role of increasing resistance, needs to withdraw flexible bulb bow 2 in cabin, pulls decompression compression bar 7 back and forth at this time, it is double
To 8 oil return of hydraulic cylinder, hydraulic push rod 9 drives rigid support 10 and flexible bulb bow 2 to shrink, until withdrawing in cabin, closing chamber
Door.
The flexible bulb bow of the utility model can be used in lowsteaming, and when high speed operation is withdrawn, and sends out to the maximum extent
Wave the effect of " resistance is reduced during low speed " of flexible ball nose Bow Construction in itself；Flexible bulb bow, can be with by rigid carrier supports
Prevent head-on incoming from leading to the deformation of flexible bulb bow to the impact of flexible bulb bow；Flexible bulb bow two sides and cabin edge
Place's sealing prevents the generation of the accident of hull leak and flexible bulb bow leakage.
