Description
Technical field
The utility model relates to a kind of ship stern brake system, and the application of this system in screw propeller propelling ship is particularly outstanding.
Background technology
Along with yacht industry is risen, people require to increase to private amusement yacht thereupon.Rapidity, safety and traveling comfort are also private boats and ships basic demands, are also the targets that ship design person pursues day by day.Yet at the boats and ships of ocean operation, rapidity and safety are but conflict bodies.Ship navigation more thereupon danger also increase, particularly when high-speed cruising, run into accident, need ship to brake and stop immediately, avoid that boats and ships hit a submerged reef, collision or the situation such as stranded.Generally, as the boats and ships of diesel propulsion, when the speed navigation with 30 joint left and right, stop immediately advancing main frame freely to stop (with water to static) downstream with the wind time by boats and ships, slide forward the distance that is about 5 times of captains, such coasting distance accident that is easy to occur to bump against and hits a submerged reef etc.Existing boats and ships generally adopt navigation electronic machine to monitor, and as radar, echosounder, water speed instrument etc., by ship's navigation environment and state are monitored, avoid ship's navigation accident to occur.
On navigating ship, can there is cover to be similar to automobile brake system? in case of emergency brake, shipping sail speed is slowed down in the short time at the utmost point, so greatly increase navigation safety.Because propeller vessel propulsion coefficient is higher, ship building is easy, and technique is simple, so generally adopt on private yacht.Utilize screw propeller boats and ships feature, design a set of stern brake system and seem particularly important.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, easy and simple to handle, can snap catch the novel ship stern brake system of boats and ships.
The technical scheme that the utility model adopts is: the utility model comprises mounting seat, guide groove, telescopic baffle, hydraulic actuating cylinder and hydraulic efficiency pressure system, described mounting seat is arranged on the rear of ship stern screw propeller, described guide groove is fixedly installed in described mounting seat, described telescopic baffle is fixed on the piston rod of described hydraulic actuating cylinder and is slidably arranged in described guide groove, the plate face of described telescopic baffle is arranged to relative with the working direction of boats and ships, and described hydraulic efficiency pressure system is connected with described hydraulic actuating cylinder and is electrically connected with the control system of boats and ships.
In described guide groove, be provided with hard nyliner.
On the piston rod of described hydraulic actuating cylinder, being provided with tightening seal washer seals.
In described a kind of novel ship stern brake system, be provided with impressed current cathodic protection system.
The beneficial effects of the utility model are: because the utility model comprises mounting seat, guide groove, telescopic baffle, hydraulic actuating cylinder and hydraulic efficiency pressure system, described mounting seat is arranged on the rear of ship stern screw propeller, described guide groove is fixedly installed in described mounting seat, described telescopic baffle is fixed on the piston rod of described hydraulic actuating cylinder and is slidably arranged in described guide groove, the plate face of described telescopic baffle is arranged to relative with the working direction of boats and ships, described hydraulic efficiency pressure system is connected with described hydraulic actuating cylinder and is electrically connected with the control system of boats and ships, so, the utility model moves by hydraulic actuating cylinder described in described HYDRAULIC CONTROL SYSTEM, piston rod on described hydraulic actuating cylinder drives described telescopic baffle to move in described guide groove, when boats and ships need to slow down while stopping, put down described telescopic baffle, described telescopic baffle extend in seawater, the flowing velocity of the seawater after screw propeller effect is high by the moving velocity than boats and ships, seawater is got on described telescopic baffle afterwards, thereby produce an application force backward, the tractive force opposite direction that this application force and boats and ships advance, it becomes the resistance that boats and ships advance, in the time of need to braking in boats and ships advance, this resistance can make boats and ships stop rapidly, avoid bumping or hitting a submerged reef, guarantee the safety of ship running.
Owing to being provided with hard nyliner in described guide groove, so, by the setting of described lining, guaranteed that described telescopic baffle is when by described Hydraulic Cylinder motion, with between guide groove, directly do not contact, the wearing and tearing of guide groove and telescopic baffle are reduced greatly, indirectly extended its service life.
Owing to being provided with tightening seal washer on the piston rod of described hydraulic actuating cylinder, seal, this has guaranteed that piston rod is not etched in seawater.
Owing to being provided with impressed current cathodic protection system in described a kind of novel ship stern brake system, so, guaranteed that whole ship stern brake system is not by marine denudation, guarantee length in its in service life.
Accompanying drawing explanation
Fig. 1 is blast structural representation of the present utility model;
Fig. 2 is Braking Analysis figure of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises mounting seat 1, guide groove 2, telescopic baffle 3, hydraulic actuating cylinder 4 and hydraulic efficiency pressure system, and described mounting seat 1 is arranged on the rear of ship stern screw propeller.Described guide groove 2 is fixedly installed in described mounting seat 1.Described telescopic baffle 3 is fixed on the piston rod of described hydraulic actuating cylinder 4 and is slidably arranged in described guide groove 2, the plate face of described telescopic baffle 3 is arranged to relative with the working direction of boats and ships, and described hydraulic efficiency pressure system is connected with described hydraulic actuating cylinder 4 and is electrically connected with the control system of boats and ships.By hydraulic actuating cylinder being controlled to controlled sliding panel run duration processed and elongation.
In described guide groove 2, be provided with hard nyliner.On the piston rod of described hydraulic actuating cylinder 4, being provided with tightening seal washer seals.In described a kind of novel ship stern brake system, be provided with impressed current cathodic protection system.
In the present embodiment, in propeller for vessels tail region, the utility model is installed, by described Driven by Hydraulic Cylinder, is driven described telescopic baffle to stretch up or down to stop that propeller race is how many, produce different brake resistances, reach its braking effect.
As shown in Figure 2, ship is with V
0speed to overtake, seawater by screw propeller effect after, with V speed, flow out backward.When current touch baffle plate, will produce effect F backward, this F is Ship brake resistance.
Seawater seawater V speed after screw propeller effect flows backward, and boats and ships are with V
0speed to overtake, it is that the speed of baffle plate is also for V that baffle plate is fixed on stern
0, the relative baffle plate relative velocity of seawater is also V+V
0.Between seawater and baffle plate, produce and interact.
Being taken at screw propeller afterbody unit mass is △ m, to slipper momentum I=F* △ t
For liquid in motion: △ m=ρ * S*V* △ t, ρ----sea water density wherein, S-----liquid flows through area, V-----water velocity, △ t----run duration;
According to the law of conservation of momentum:
F*△t=△m*(V+V
0)-△m*?V
0
F=ρ * S*V
2formula 1-1
By formula 1-1, can be obtained, the directed force F size on slipper, has relation with fluid density, area of contact and flow velocity.
By upper analysis, can be obtained, can change the area of telescopic baffle, to change the size of its braking force.Therefore, can, according to not shipmate type, under different ship speeds, can be equipped with different area dash area plate.
The utility model is applied to Ship brake field.
