Description

A kind of luminous lifebuoy

Technical field

The utility model relates to the buoy quoit field, relate in particular to a kind of can be under dark surrounds self luminous buoy quoit.

Background technology

Buoy quoit is the life that vessel must be equipped with, and when ship is wrecked, can reach the purpose of rescue life.The function singleness of present buoy quoit can only provide floating function, in case ship at night or greasy weather disaster takes place, also be difficult to found by the rescue worker even the drowning people puts the lifeguard, thereby the probability that causes being rescued reduces.

The utility model content

In view of this, the utility model provides a kind of luminous lifebuoy, and buoy quoit can be come to light in dark surrounds fast, has improved drowning people's the probability of being rescued.

For addressing the above problem, the utility model provides a kind of luminous lifebuoy, comprising:

The ring vaccum pneumatophore of processing by waterproof material;

Air extractor vent is arranged on the said pneumatophore;

Be used to seal the seal cover cap of said air extractor vent;

By the luminescent layer that phosphor material forms, covering is arranged on the outside face of part at least of said pneumatophore.

Optional, above-mentioned luminous lifebuoy also comprises:

A plurality of clear coats of stoping different colours light to pass through of being used to cover the diverse location on the surface of said luminescent layer.

The utlity model has following beneficial effect:

When 1, this buoy quoit perhaps had light-illuminating by day, the luminescent layer of coating can absorb energy, and changes the ability that absorbs into visible light; When do not have sunshine or light-illuminating night; It still can continue luminous, thereby can come to light fast, has improved drowning people's the probability of being rescued.

2, because the initial briliancy of luminescent layer is the every sq m of 7400cd, therefore can guarantee buoy quoit at any time all be in luminous state more than 80 hours visual afterglow time.

Description of drawings

Fig. 1 is the structural representation of the luminous lifebuoy of the utility model embodiment;

Fig. 2 is the structural representation at the surface coated clear coat of luminescent layer of the utility model.

The specific embodiment

The luminous lifebuoy of the utility model embodiment; On outside face, be coated with the luminescent layer that one deck is formed by phosphor material, absorb energy when this luminescent layer receives light source irradiation, and change the ability that absorbs into visible light; Excite can continue after stopping luminous; Therefore in the environment of dark, can come to light fast, improve drowning people's the probability of being rescued.

Please refer to Fig. 1, the luminous lifebuoy of the utility model comprises:

The ring vaccum pneumatophore of processing by waterproof material 101;

Air extractor vent 102 is arranged on the said pneumatophore 101;

Be used to seal the seal cover cap 103 of said air extractor vent 102;

By the luminescent layer (scheming not shown) that phosphor material forms, covering is arranged on the outside face of part at least of said pneumatophore 101.

In order further to strengthen the function of reminding; Have only the light (like redness, green etc.) of part particular color to pass through in the light that can also make the different piece of whole luminescent layer send; Therefore can different clear coats be set at the different parts on the surface of said luminescent layer; Make whole buoy quoit present color effect, further strengthen the function of reminding.

That is to say that the buoy quoit of the utility model also comprises:

A plurality of clear coats of stoping different colours light to pass through of being used to cover the diverse location on the surface of said luminescent layer.

As shown in Figure 2, above luminescent layer, be coated with following 4 kinds of clear coats:

Red coatings, it only allows redness to pass through;

Green coating, it only allows green to pass through;

Blue coating, it only allows blueness to pass through;

Yellow coating, it only allows yellow to pass through;

Because 4 coatings are positioned at different positions, then can send redness, green, blueness and red light in the different piece of buoy quoit, thereby make integral body present colored effect, more eye-catching.

In the specific embodiment of the utility model; In order to guarantee that buoy quoit can both emit beam at any time; Phosphor material can adopt artificial synthetic long Persistence and high brightness fluorescent materials to process; This long Persistence and high brightness fluorescent materials is a matrix with the alkali earth metal aluminate of boracic, and more than one RE element is an activator, and its chemical molecular formula is: MO _n[(Al _1-aB _a) _2-b/3O _3-b(OH) _b]: cRE, wherein:

M representes to be selected from least a alkaline earth in magnesium, calcium, strontium or the barium;

RE representes to be selected from lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, at least a rare earth element in the lutetium;

N is smaller or equal to 10, more than or equal to 0.5;

A is smaller or equal to 0.5, more than or equal to 0.0001;

B is smaller or equal to 2, more than or equal to 0.0001;

C is smaller or equal to 0.6, more than or equal to 0.0001;

Part is by OH displacement at least for oxygen atom in the crystal structure that burns till body that above chemical molecular formula is represented, and it is to carry out wet grinding through the material solution with one or more, makes each composition in the raw material be ground to particle diameter and prepares for the 50-10000 nanometer.

And the synthetic long Persistence and high brightness fluorescent materials of above-mentioned manual work can prepare through following method:

At first, take by weighing raw material, and it is ground to particle diameter is the 50-10000 nanometer by proportioning;

Secondly, the raw material after grinding is inserted crucible, and this crucible is put into the pressure electric furnace, under reducing atmosphere, calcining is 2-5 hour under the 600-1200 degree celsius temperature;

Once more, will burn till body and from electric furnace, take out cool to room temperature;

At last, the cooled body that burns till is ground to form powder.

The initial briliancy of the luminescent powder of preparation is the every sq m of 7400cd as stated above, and visual afterglow time is more than 80 hours.

Certainly; Should be understood that above-mentioned phosphor material also can other phosphor material, like disclosed phosphor material in No. 95109878.0 patents; And for example disclosed phosphor material etc. in 97100694.6,99100285.7, No. 98123460.7 patents is not described at this one by one.

The buoy quoit of the utility model has following beneficial effect:

When 1, this buoy quoit perhaps had light-illuminating by day, the luminescent layer of coating can absorb energy, and changes the ability that absorbs into visible light; When do not have sunshine or light-illuminating night; It still can continue luminous, thereby can come to light fast, has improved drowning people's the probability of being rescued.

2, because the initial briliancy of luminescent layer is the every sq m of 7400cd, therefore can guarantee buoy quoit at any time all be in luminous state more than 80 hours visual afterglow time.

The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
