Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

A buoy easy to identify water leakage is characterized in that a marker 200 for distinguishing whether the buoy leaks water is arranged in a buoy body 100 of the buoy, the marker 200 is in different states before and after the marker reacts with water, and the marker 200 can generate obvious marks on the appearance of the buoy when meeting water, so that an inspector can very quickly determine whether the buoy leaks water based on obvious visual sense difference, and the buoy is explained through the following embodiments.

Example one

Referring to fig. 1 and 2, the identifier 200 uses a humidity test indicator card to determine whether water leaks. Specifically, the float can be an HDPE float, the body 100 is provided with a transparent window 10 for viewing the internal condition of the float, and the transparent window 10 can be disposed on the upper surface of the body 100, but the position of the transparent window 10 is not limited to the upper surface of the body 100, and it is also possible to dispose the transparent window on the side surface of the body 100 or any other place that can be visually seen by a person. Transparent window 10 can adopt the organic glass board to make, for example, body 100 upper surface sets up 10 cm's opening, the organic glass board size that corresponds adapts to with the opening, pass through glue sealing connection between organic glass board and opening, the organic glass board is still pasted on the one side that is located body 100 inside and is had the paster board 40 that is 25 degrees contained angles with the glass board, this paster board 40 upper surface is pasted and is had above-mentioned humidity test indicator card, humidity test indicator card is prior art, its principle is that moisture in the air makes the indicator card present different colours, technical staff in the art can directly obtain this humidity test indicator card. Further, in order to avoid the interference of the indication card caused by the original air with a certain humidity inside the main body 100 during the manufacturing of the main body 100, a pack of desiccant 300 may be placed into the main body 100 from the seal of the cylinder 30 before the main body 100 is packaged, a person skilled in the art may directly obtain the desiccant 300, the desiccant 300 may absorb the water vapor in the air inside the main body 100, and keep the inside of the main body 100 dry during the long-term use, but the released desiccant 300 may absorb limited water, if the float leaks, the water leaking into the main body 100 may quickly consume the desiccant 300, and the air inside the main body 100 is humidified, at this time, the humidity test indication card may change color due to the humidification of the air, and the inspector may visually check the color change of the indication card through the transparent window 10, and then quickly determine whether the float leaks water.

Further, the transparent window 10 can be arranged at any position of the buoy as long as the transparent window 10 can observe the internal marker 200 of the buoy. It will be appreciated by those skilled in the art that the general buoy body 100 comprises a cover 20 and a bowl 30, and the transparent window 10 may be provided on the cover 20. Specifically, a space 21 communicated with the inside of the main body 100 is provided on the cylinder cover 20, and then a marker 200 for distinguishing whether the float leaks or not is provided in the space 21, and the marker 200 shows different states before and after the action with water. As shown in fig. 11 to 14, the embodiment of the cartridge cover 20 and the placement of the identifier 200 can be found in example eight and example nine. In this embodiment, the humidity test indication card may be attached to the transparent window 10 of the cover 20, and the state of the humidity test indication card may be recognized through the transparent window 10 of the cover 20.

Example two

Referring to fig. 3 and fig. 4, the main difference between the present embodiment and the first embodiment is: the marker 200 is a water-variable color substance disposed on the absorbent package, and may be, for example, anhydrous copper sulfate powder wrapped by the absorbent package or a water absorbent material coated with an organic reagent disclosed in patent ZL201010605189.9, and the application of the anhydrous copper sulfate powder will be described in detail below. The side of the plexiglass plate on the transparent window 10 inside the body 100 is applied with the marker 200. it should be understood by those skilled in the art that the marker is not limited to being applied on the plexiglass plate, but can be applied on a place easily visible through the plexiglass plate, and the marker can be applied on the patch plate 40 by using the patch plate 40 in the first embodiment, which forms an angle of 45 degrees with the glass plate. Similarly, before packaging the body 100, a pack of desiccant 300 can be placed into the body 100 from the seal of the cylinder 30, when the buoy leaks water, the water leaking into the body 100 can be absorbed by the anhydrous copper sulfate powder through the water absorption package after the desiccant 300 is consumed, the anhydrous copper sulfate powder turns blue when encountering water, the anhydrous copper sulfate powder is dissolved in the water and absorbed by the package along with the water, the package can be selected to be a white non-woven bag, the non-woven bag turns blue into the whole body after absorbing blue copper sulfate liquid, an inspector can visually check the color change of the water absorption package through the transparent window 10, and then whether the buoy leaks water can be quickly judged.

EXAMPLE III

Referring to fig. 5, the main differences between the present embodiment and the first embodiment are: the marker 200 is required to be soluble in water and the color of the marker 200 is different from the color of the body 100, and the patch plate 40 is not required to be adopted in the embodiment. The more common body 100 colors now include gray, and therefore, marker 200 may employ white salt crystals, which are color-different from gray. The inner wall of the bottom of the cavity of the body 100 extends upwards to form a first gray net rack 50 corresponding to the position of the transparent window 10, when the body 100 is packaged, the large table salt crystals after compression and shaping are placed in the first gray net rack 50, and the first gray net rack 50 and the large table salt crystals form a visual obvious difference. When the water leaks from the buoy, the large salt crystals are dissolved after the water leaking into the body 100 is consumed by the drying agent 300, and the first gray net rack 50 becomes empty after the large salt crystals are dissolved, so that an inspector can check whether the large salt crystals exist in the first gray net rack 50 through the transparent window 10 to quickly judge whether the water leaks from the buoy.

Example four

Referring to fig. 6, the main differences between the present embodiment and the third embodiment are: the marker 200 is a substance which is dissolved in water to generate a color different from that of the body 100, and the substance can be potassium permanganate powder, and a net rack is not required to be arranged in the embodiment. Before the buoy is packaged, a small amount of potassium permanganate powder is uniformly sprayed in the buoy, the small amount of powder can be adsorbed on the surface of the inner wall of the body 100, the potassium permanganate powder is dispersed and cannot completely cover the surface of the material of the body 100, and scattered dark powder is dispersed on the gray bottom surface when the inside of the buoy is checked through the transparent window 10. Once the buoy leaks water, potassium permanganate in the buoy is rapidly dissolved in the leaked water, and due to the fact that the potassium permanganate is dark in color, a small amount of potassium permanganate enables the internal leaked water to change color, so that purple liquid flowing into the buoy flows, and inspectors can check whether flowing purple liquid exists in the buoy through the transparent window 10 to rapidly judge whether the buoy leaks water.

EXAMPLE five

Referring to fig. 7, the main differences between the present embodiment and the third embodiment are: the marker 200 is an insoluble core wrapped with a soluble shell, and the color or brightness of the insoluble core is different from that of the body 100 or the soluble shell. Specifically, the body 100 is made of a gray HDPE material, the soluble shell can be made of white starch through compacting and shaping, the insoluble core can be directly made of a black plastic core, and the starch shell is wrapped outside the plastic core to form the white marker 200. The corresponding position of the transparent window 10 in the cavity of the body 100 extends inwards to form a second gray rack 60, when the body 100 is packaged, the white marker 200 is placed on the second gray rack 60, and the second gray rack 60 and the white marker 200 form a visual obvious difference. When the water leaks from the float bowl, the water vapor or splashed water splash leaking into the body 100 can quickly dissolve and break the starch shell of the white marker 200 and then crush the starch shell after the water has consumed the drying agent 300, so that the inner black core body is exposed, the black core body can form obvious visual difference with the second gray net frame 60, and an inspector can check the color of the marker 200 on the second gray net frame 60 through the transparent window 10 to quickly judge whether the water leaks from the float bowl. Certainly, inside black core can also be replaced with the night light stone, and the artificial night light stone can directly be obtained to the technical staff in the art, and the afterglow of its radiation can't be seen when the starch shell is wrapped up in to the night light stone surface, but once outside starch shell is dissolved, the afterglow of night light stone will be released, night inspection personnel need not be close to the flotation pontoon even, directly can directly discover the flotation pontoon that leaks from luminous transparent window 10.

EXAMPLE six

Referring to fig. 8 and 9, in the present embodiment, the identifier 200 is selected to be a packaged light source, and the packaged light source includes a power source and a light source connected in series, and the power source and the light source are packaged in a package. The packaging body can be a hollow cavity with a glass side wall, the packaging body is integrally sealed, and water cannot invade into the hollow cavity. The power supply and the light source form an open circuit and are fixed in the hollow cavity, two ends at the open circuit position of the circuit penetrate through the packaging body and are exposed outside the packaging body, and the connection position of the ends and the packaging body keeps sealed. Under normal state, the circuit is in open circuit state, the marker 200 does not emit light, but once the buoy leaks water, the packaging body is soaked in the leaked water, two ends are obtained at the open circuit position of the water leakage conduction circuit to form a closed loop, and the light source emits warning light under the support of the power supply. The main body 100 is also provided with a transparent window 10 for viewing the internal condition of the buoy, and the light emitted by the light source can penetrate through the transparent window 10, so that an inspector can quickly find out the buoy fault at night. Further, since the light emitting body emits relatively strong light, if the float bowl can sufficiently transmit the light, the transparent window 10 does not need to be formed on the body 100. The desiccant 300 may not be placed in this embodiment because a small amount of moisture in the air will not affect the packaged light source.

EXAMPLE seven

Referring to fig. 10, in the present embodiment, the marker 200 is a fluorescent powder or a luminous powder wrapped by a water-degradable and light-tight package, such as: dark paper with poor light transmission and the like can be directly obtained by technical personnel in the field, fluorescent powder or luminous powder is placed in a float bowl before the paper bag with the fluorescent powder or luminous powder is packaged in a body 100, the float bowl is not leaked, the fluorescent powder or luminous powder is wrapped by the paper and cannot radiate light outwards, once the float bowl leaks, the paper is soaked due to water leakage, the fluorescent powder or luminous powder is scattered or dissolved in water, a transparent window 10 capable of seeing the internal condition of the float bowl is also arranged on the body 100, when an inspector irradiates purple light from the transparent window 10 to the inside, the fluorescent powder emits glaring fluorescence, and if the luminous powder is luminous, the fluorescent powder directly emits light. Further, if the luminous liquid generated after mixing can emit light with sufficient intensity, the transparent window 10 does not need to be opened on the body 100.
