Technical field
The utility model relates to the hatch door on a kind of naval vessel, is the hatch door with sound insulation choke effect specifically, is particularly useful for positions such as the engine casing of the auxilliary naval vessel of the army of being installed in, civilian and maritime works's boats and ships and control room.
Background technology
As everyone knows, in ship domain, naval vessel, civilian and the cabin of maritime works's boats and ships and the power set that the control room is mainly used in arranging the naval vessel are assisted by army, these power set can produce huge noise and waste gas in running, therefore, hatch door with sound insulation choke function need be set in the exit in this class engine casing and control room, when its effect is isolated cabin and the operation of control indoor equipment to noise and the air pollution in other space, inside, naval vessel.
Traditional sound insulation choker that is used for cabin and control room all is made up of door-plate and the doorframe of hollow, door-plate and doorframe are mostly made by steel material, and their inside is filled with sound absorption material, with between doorframe, also be provided with weather strip around the door-plate, weather strip can be fixed on the doorframe, also can be fixed on the door-plate.This sound insulation choker can reach the effect of noise reduction by its inner sound absorption material of filling, and contacts to realize sealing the effect of choke by weather strip and the face face between door-plate or doorframe sheet material.But, because this sound insulation choker only adopts one weather strip to carry out the face face with sheet material and contacts sealing, when excessive or weather strip is aging when the pressure in cabin or the control room, indoor gas still can pass between weather strip and sheet material, so just influenced the sealing performance of sound insulation choker, make that simultaneously the defening effect around the door-plate is relatively poor, and gas can produce frictional force to weather strip when passing, cause the damage of weather strip easily.
The utility model content
Problem to be solved in the utility model provides a kind of naval vessel sound insulation choker, and this sound insulation choker has higher sealing and sound insulation property, and its weather strip is not fragile.
For addressing the above problem, take following technical scheme:
Naval vessel of the present utility model comprises door-plate and doorframe with the sound insulation choker, and one group of corresponding sides of door-plate and doorframe are hinged, between the door-plate except hinged limit and doorframe retaining mechanism arranged.Described door-plate and doorframe are hollow form, and its inside is filled with sound insulating material.The inside edge that is characterized in described doorframe lateral surface has along circumferentially and be the convex tendon of horizontal arrangement, and the door-plate at this convex tendon correspondence position fixedly has weather strip, perhaps the edge of door-plate medial surface has along circumferentially and be the convex tendon of horizontal arrangement, and at the doorframe of this convex tendon correspondence position weather strip is arranged fixedly.
The further improvement of the utility model scheme is that the edge of the inside edge of described doorframe lateral surface and door-plate medial surface all has along circumferentially and be the convex tendon of horizontal arrangement, and on the door-plate of the convex tendon correspondence position of doorframe and on the doorframe at the convex tendon correspondence position of door-plate weather strip is being arranged fixedly all.This scheme is to have increased diatom face contact sealing on the basis of first scheme again, and its sealing performance is the twice of first scheme.The protrusion length of convex tendon is greater than the horizontal breadth of weather strip on the doorframe on the described doorframe, and the protrusion length of convex tendon is greater than the horizontal breadth of weather strip on the door-plate on the door-plate, this can make door-plate in off position down, toughness by weather strip, convex tendon can be inserted in the weather strip fully, namely make the angle of convex tendon both sides and weather strip interphase interaction power increase as far as possible, thereby increase weather strip in the compactness of convex tendon both sides, be conducive to better to realize that convex tendon contacts sealing with line face between weather strip.
The further improvement of the utility model scheme is to be coated with one deck sound insulation damping paint on the inner surface of described door-plate inner panel, namely on the basis of filling sound insulating material, has increased one deck sound insulation coating in original door-plate, thereby has increased the sound insulation property of door-plate.
In above-mentioned arbitrary scheme, the sound insulating material of filling in described door-plate and the doorframe is highdensity rock wool, and this material has good sound absorption, defening effect.
Take such scheme, have the following advantages:
Because naval vessel of the present utility model has along circumferential and be the convex tendon of horizontal arrangement with the inside edge of doorframe lateral surface of sound insulation choker, and the door-plate at this convex tendon correspondence position fixedly has weather strip, perhaps the edge of door-plate medial surface has along circumferentially and be the convex tendon of horizontal arrangement, and the doorframe at this convex tendon correspondence position fixedly has weather strip, namely when door-plate is in closed condition, be to be squeezed in to realize sealing on the weather strip i.e. line face contact sealing by convex tendon between the medial surface of door-plate and the lateral surface of doorframe.At this moment, the direction of the interaction force between convex tendon both sides and weather strip (optimum state is 180 °) in a certain angle, gas is wanted to pass from line face contact point, must turn round, according to mechanics principle, under the constant situation of gas pressure direction, its pressure of meeting weakening that flows that turns round of gas, namely with respect to sheet material in the prior art for face face between weather strip contact (direction that is interaction force is identical all the time), the sealing means of line face contact can weaken the air pressure that bear in its seal point outside, thereby the enhancing sealing performance also can improve door-plate defening effect all around simultaneously.In addition, the compression of almost completely sealed of weakened pressure was born when gas turned round, and this just greatly reduces the frictional force that gas acts on weather strip, makes weather strip not fragile.
