Description

The sealed type anti-exposure coveralls

Affiliated technical field the utility model belongs to the lifesaving category, is lifesaving appliance in a kind of water, can be widely used in various waters, especially lays particular emphasis on offshore applications.

In the various one-off life that is equipped with on the present ship of background technology, life jacket and buoy quoit are the most general.But the two only can provide buoyancy, and other protection can not be provided.Because water absorbs the ability of heat and substantially exceeds air, be to cause death to die often so the people has grown the time in water because of low temperature damages, lower this process of water temperature is just faster.Now also be equipped with a kind of insulated cold wear aboard ship, though it has heat insulation function, women's head-ornaments portion is exposed, watertight not, and the people is in case immersion, and body temperature will be difficult to keep, and can't avoid stormy waves choking of people's snout position irritated and to impact.So existing single life is unfavorable for all that the people drifts for a long time and waits to rescue and save oneself in water, be difficult to guarantee safety.

The purpose the purpose of this utility model provides a kind of life combination suit that can carry out sealed type protection to the human body whole body, thereby it makes the people completely cut off with water to avoid injury from low temperature, also protected user's women's head-ornaments portion to make it to avoid the direct invasion and attack of stormy waves; And satisfy the besoin de respirer of user when the water surface is drifted by its distinctive breather apparatus.This life combination suit also is equipped with the radar return device simultaneously, helps carrying out of search-and-rescue work, thereby improves drowning people's chance for survival.

Technical scheme is for achieving the above object, and the utility model is obeyed the sealed type anti-exposure coveralls that these several parts are formed by the helmet, outer cover, breather apparatus, radar return device and watertight, is called for short life combination suit.It can have two kinds of embodiments, and its outward appearance and performance also are not quite similar, and have his own strong points.See first kind below earlier.

This situation is the mode that outer cover combines with the helmet.At first be the helmet, it covers user's head up to neck is whole, and head is played a protective role.The helmet is provided with an observation window to be opened/closed at eye, can reach the watertight state when it is closed.Outer cover is covered on helmet outside again, the part beyond the helmet face is covered, the function of outer cover mainly is the breather apparatus that holds with the crash helmet outside.So just between the outer cover and the helmet, form a mezzanine space, with insulation strip this separated by spaces is become several isolated mutually chambers then, inlet chamber and discharge chamber are wherein arranged.The airtight of water tightness of insulation strip own, thus between inlet chamber and the discharge chamber because of the function difference, also be airtight of water tightness, can be communicated with between the identical chamber of function.Also floor can be set between insulation strip.Dug the ventilation drain gutter above the floor.In helmet the inside, people's face is provided with a spray mask again, and people's nose and mouth are covered, and spray mask is subjected to the protection of the helmet.Two systems are installed on the spray mask, and one is air system, and one is exhaust system.Air system comprises a breather cheek valve, draws a flexible pipe from valve, is upward through the helmet and enters mezzanine space, obtains air supply from inlet chamber; Exhaust system comprises an one-way exhaust valve, also draws a flexible pipe from valve, be upward through the helmet and enter discharge chamber in the mezzanine space, during breathing via the outside exhaust of discharge chamber.The opening of two flexible pipes in interlayer all has the opening fender guard.In the bottom of inlet chamber and discharge chamber, connection for bbreather pipe all is installed, the function of connection for bbreather pipe is to guarantee mezzanine space and extraneous air inerchange, and stops water to enter in the interlayer.Like this, when the people breathed, air entered from connection for bbreather pipe, entered spray mask through inlet chamber, flexible pipe and breather cheek valve; Otherwise during exhaust, air is discharged through another connection for bbreather pipe through one-way exhaust valve, flexible pipe, discharge chamber again.According to design,, just can satisfy user's besoin de respirer as long as an inlet chamber and a discharge chamber are arranged and belong to their that connection for bbreather pipe normal operation.Consider that on the water especially marine often stormy waves is very big, so inlet chamber and discharge chamber all be configuration in pairs, they apart from one another by.No matter like this from which direction, the connection for bbreather pipe that all has an inlet chamber and a discharge chamber at least and belong to them is in work, so when simultaneously being subjected to the stormy waves influence, in the time of can not bringing into play its whole usefulness, can coming Mi to mend by another side; Or the satisfied needs of breathing are worked on the two sides simultaneously.So just formed a complete respiratory system, solved the breathing problem of user at the water surface; The helmet itself and outer cover all are watertights simultaneously, guarantee that user's head does not contact with water, have solved the protection question of head effectively.The helmet with cover on neck and watertight clothes outward and closely link to each other.The watertight clothes can be protected the part below the head.

The watertight clothes are provided with buoyant device at shoulder chest place, and enough buoyancy can be provided; Also be provided with other annex such as watertight waistband above.The complete watertight of itself is only established a watertight zip fastener at chest abdomen place, from wearing, take off this part clothes here.After watertight zip fastener closes, just be returned to the watertight state, human body and water is isolated.Though itself has certain winter protection effect, what mainly pay attention to is the waterproof effect and the intensity of itself, and the winter protection function then mainly realizes by people's oneself clothes.Because the most a good fit coldproof material of most convenient is people's oneself a townwear.The same day hot air heating and the time, people's clothing is few, but this moment, water temperature was also high, and did not require too many dress; Water temperature is low when being cold, but at this moment people wear also many.The two is consistent, and is cooresponding, and watertight clothes itself design based on this point, so it is looser light and handy, dress is convenient rapidly, and this is its characteristics.As long as suitable wearing the clothes before following water, or use other warm materials more, again in conjunction with the watertightness performance of watertight clothes, like this, it just and the helmet together, solved protection questions such as waterproof to whole human body, low temperature satisfactoryly.

In above-mentioned respiratory system, the flexible pipe on the check valve all is to stretch out upward, can't discharge the moisture in the spray mask.Therefore,, can from spray mask, establish a unidirectional exhaust outlet valve downwards again,, also can discharge the moisture content liquid in the mouth mask from not only directly outwards exhaust here as to improvement of the present utility model.

As to further improvement of the utility model, when using the exhaust outlet valve, one-way exhaust valve originally seems not essential, also can leak portion gas, makes the exhaust outlet valve can't normal operation.One-way exhaust valve can be designed to rotary type, when its Rotate 180 was spent, blow off valve had just become air inlet valve for this reason.This is not only to equal to have closed blow off valve, has also strengthened the air feed effect, makes original all connection for bbreather pipe and air cavitys all belong to air system, air feed in the helmet simultaneously, and the function of exhaust system is born alone by the exhaust outlet valve; When its rotation 090 is spent, just become normally open valve, discharge chamber has originally just become the air storage chamber.Like this, one-way exhaust valve has just become multifunction valve, and the function of discharge chamber is originally also changed along with its function conversion.This just provides a selection to the user, helps using in different environment.

Because at outer cover the inside, the spread geometry of insulation strip in mezzanine space, and the angle between it and the floor, all be vertical substantially; And they are all perpendicular with the underlying helmet surface.These all match with some characteristics of radar corner reflector.So, principle according to radar corner reflector, under the prerequisite that does not influence other functions, combine as long as the radar return material is arranged on the above-mentioned member and with the function and the shape of these members, their overall combined shaped and the character that has, just make it become the radar return device, have the partial function of radar corner reflector.It can be embodied by different manufacture methods and form.Its appearance will be very beneficial for using radar to carry out the weather-proof rescue operation, overcome the influence that bring dark night, and the hope that persons falling in water is rescued is bigger.

Second kind of embodiment of the present utility model is that the outer cover and the helmet are separated.In first kind of mode, outer cover is to obtain buoyancy and stability from human body and watertight clothes there, can remain on the water surface to guarantee the connection for bbreather pipe that is positioned at the outer cover bottom; Buoyancy and stability ability normal operation also must be arranged after outer cover separates now.So, outer cover at first with one independently buoyancy aid combine, have enough buoyancy; Counterweight is set then, to guarantee that buoyancy aid is just floating on the water surface all the time.Outer cover is buckled on the buoyancy aid, and portion forms the space that shape is more regular within it, and insulation strip and floor as first kind of mode, also isolate inlet chamber and discharge chamber in the space, also be equipped with connection for bbreather pipe below, form an outer cover buoyancy aid.Air inlet valve and blow off valve from the spray mask drawn air inlet pipe and freeing pipe then, passes the helmet, is connected with the outer cover buoyancy aid and enters outer cover inside, is connected with discharge chamber with cooresponding inlet chamber, forms complete respiratory system.In this mode, air inlet pipe and freeing pipe are withstand voltage formulas, and the external application protective cover, make the withstand voltage breathing pipe of this root have enough intensity, during use it and Life belt are tightly linked together.Because Life belt is made like this and can be avoided when the outer cover buoyancy aid is subjected to impacting the helmet being caused excessive involving in stormy waves near people's center of gravity.And the helmet is not owing to there being the Additional Protection of outer cover, so will be strengthened.This frame mode has following advantage: the first has certain diving performance.After adding counterweight on the watertight clothes, certain degree of depth of just can diving beneath the water.When boats and ships screw propeller takes place in operation twine class accidents such as net, can use it to carry out under-water operation.A kind of means of saving oneself have just been given more than the crewman so be equipped with it on the ship.It two is owing to there has not been the restriction of the helmet, so the radar return device also can be done more perfectly.

Beneficial effect in sum, the utility model adopts the common material manufacturing, complete function, stable performance, easy to use.And be easy to store, daily service is easy.
