Abstract

A kind of underwater hatch door, check passage is formed with flexible valve, emitting substance can squeeze out cabin by force, after going out cabin moment close automatically, can also by the way of non-obtrusive extruding opposing traffic；Flexible valve uses to be combined with stretch-proof, anti-puncture, sealing, anti-corrosion, anti-halobios adhersion, fire resisting, wear-resisting or lubricating function multiple material, adapts to high temperature, high pressure, the use environment of high corrosion；Simple in construction compared with rigid hatch door, convenient to use, manufacture and maintenance cost are relatively low, fill up current torpedo, Underwater Missile transmitting and personnel's article and come in and go out under water the blank in field.

Description

A kind of underwater hatch door

Technical field

The present invention is on a kind of underwater hatch door.

Background technology

Torpedo-launching, the launching pod of guided missile typically use rigid hatch door to naval vessels under water at present, and its shortcoming is：Upstream face bears very big hydraulic pressure when hatch door is opened, if emitting substance directly hits door and goes out to run into very big frontal drag to race against time, not only need bigger thrust, the damage of hatch door and emitting substance can also be caused, therefore first extraneous hydraulic pressure is balanced toward injection gas in cabin or water, then hatch door is opened, then just igniting transmitting, some finally at once will also shut hatch door and prevent into water, not only operating process is long to bungle the chance of winning a battle, and complicated raising fault rate and operational error rate, manufacture and maintenance cost are also higher.The hatch door to come in and go out under water for personnel, article equally there is also it is such the problem of.

The content of the invention

It is an object of the invention to provide a kind of simple in construction, convenient to use, manufacture and the relatively low valve flexibility hatch door of maintenance cost, the blank of current underwater hatch door is filled up.The present invention includes door leaf（1）, doorframe（4）, it is characterised in that：Door leaf（1）It is a kind of flexible check spacer of valve；Door leaf（1）Work in environment, automatically turned on when the pressure in cabin is more than pressure out of my cabin under water, on the contrary then automatic close is prevented into water；Object can pass through direct forward extrusion door leaf in cabin（1）Go out cabin by force.

The door leaf of the present invention（1）The flexible stretching reinforcement of upstream face（2）.

The doorframe of the present invention（4）There is drain port top（3）Lead to door leaf（1）Upstream face.

The flexible moulding capsule of the present invention（5）With door leaf（1）It is connected, fills water or sweeping appearance is presented later in air, be covered in door leaf（1）Outside, rate of tension can be adjusted according to extraneous variation in water pressure dynamic regulation water injection rate.

The present invention has opening device（6）With door leaf（1）It is connected, can be door leaf（1）The non-obtrusive duplex channel being pressed through is unfolded into advance.

The door leaf of the present invention（1）, reinforcement（2）Or moulding capsule（5）It is combined using with stretch-proof, anti-puncture, sealing, anti-corrosion, anti-halobios adhersion, fire resisting, wear-resisting or lubricating function multiple material.

Brief description of the drawings

Fig. 2 is the embodiment with moulding capsule.

Fig. 3 is the internal structure side sectional view of this underwater hatch door.

Embodiment

As shown in figure 1, the present invention includes doorframe 4, can be used exclusively for fixing being used for the hole type partial structurtes for fixing door leaf 1 on the part or nacelle of door leaf 1；Door leaf 1 is a kind of flexible check spacer of valve, and each hatch door forms check channel design or each hatch door by three participations of door leafs 1 door leaf of one or other quantity；Under water in environment, automatically turned on when the pressure in cabin is more than pressure out of my cabin, on the contrary then automatic close is prevented into water；Because being flexible article, for back side there is also inclination angle, to going out for the thing of cabin for tip moulding, frontal drag is smaller, can go out cabin by force by direct forward extrusion door leaf 1.

As shown in figure 1, in order to improve the tensile strength of door leaf 1, upstream face is provided with soft stretch reinforcement 2.

As shown in Figure 1, in order to which the water squeezed outward when door leaf 1 is opened outwardly is evacuated in time, water outside when inwardly closure supplements inwards in time, so as to improve the sensitivity that door leaf 1 is opened and closed, drain port 3 can be set to lead to the upstream face of door leaf 1 in the top of doorframe 4.

Door leaf 1 shown in moulding capsule 5 and Fig. 1 as shown in Figure 2, moulding capsule 5 are arranged on the outside of door leaf 1, are one kind with valvular flexible cystic structures；Moulding capsule 5 is equal with the quantity of door leaf 1, and position corresponds；Moulding capsule 5 is before water is injected; it is close to the outside of door leaf 1; it can stick out when filling water and closing after valve and keep rigidity; the entirety that combines is presented sweeping appearance and is covered in the outside of door leaf 1; both 1 rough surface of door leaf can have been avoided to influence ship navigating speed, door leaf 1 can have been shielded again；Rate of tension can be adjusted according to extraneous variation in water pressure dynamic regulation water injection rate.

As shown in figure 3, in order to be passed in and out by the way of non-obtrusive extruding from door leaf 1, opening device 6 is set to be rotatablely connected on doorframe 4, its free end is connected with door leaf 1, and the non-obtrusive duplex channel being pressed through door leaf 1 is unfolded into can in advance when swinging out；Opening device 6 is from the inner thrust to exert a force outward or from center to surrounding or tension structure；Opening device 6 can operate out of cabin, can also be operated from out of my cabin；Opening device 6 is started using manpower or electronic mode.

Moulding capsule 5 shown in door leaf 1, reinforcement 2 or Fig. 2 shown in Fig. 1 is combined using with stretch-proof, anti-puncture, sealing, anti-corrosion, anti-halobios adhersion, fire resisting, wear-resisting or lubricating function multiple material；Matrix is using high-tensile, high elastic modulus, pliability are good, resistant to elevated temperatures material, including but not limited to carbon fiber, glass fibre or aramid fiber braid；Matrix outer layer is using the good material of corrosion-resistant, high temperature resistant, heat-proof quality, including but not limited to modified rubber；The closed calmodulin binding domain CaM surface of door leaf 1 is good using not only corrosion-resistant, high temperature resistant, heat-proof quality, and watertightness, air-tightness also preferable material, including but not limited to modified rubber；In order to mitigate the friction between cabin thing and door leaf 1, corrosion-resistant, high temperature resistant lubriation material can be coated in the back side of door leaf 1；The antibiont attachment measure that the long-term naked portion faces being exposed on the outside use includes but is not limited to coat antibiont attachment coating or using the cleaning of cavitation water flow jet.
