Description

Leakage display device

The invention relates to a leakage display device, in particular to a leakage display device capable of converting the occurrence of leakage into a visual reminder, thereby forming a warning mechanism.

In the current public places, electric power systems such as street lamps or utility poles have occasional leakage, but the situation of leakage is not visible to the naked eye, and children often inadvertently touch and cause injuries. Accordingly, the present invention provides a device that visualizes leakage current, suitable for installation in public places, particularly in parks, to alert children or parents to light leakage around the lamppost or utility pole to improve public safety.

In view of the problems of the prior art, it is an object of the present invention to provide a leakage display device characterized by a change in color of an electrosensitive substance to form a warning mechanism.

According to an object of the present invention, a leakage display device is provided, which comprises a sensing unit having a pattern layer and an electro-sensitive substance layer, and the electro-sensitive substance layer is disposed at the bottom of the pattern layer. The electro-sensitive substance layer is filled with an electro-sensitive substance, and the electro-sensitive substance may be a magnetic substance.

In other words, the magnetic substance filled in the layer of the electro-sensitive substance changes due to an external electric power. In other words, when the range of the external power is extended to the magnetic substance in the layer of the electro-sensitive substance, the external electric power additionally generates a magnetic force which reacts with the magnetic substance to cause mutual absorption or mutual exclusion. Therefore, by this reaction, the magnetic substance undergoes a magnetic transition, thereby causing a magnetic substance originally having a color to undergo a change in the exposed color by a reaction of a magnetic force. That is to say, the change in color is revealed by the pattern layer provided on the layer of the electrosensitive substance.

Generally speaking, the original pattern layer has a totem design, and the totem design includes at least one see-through portion, and an outside person can see the color of the magnetic substance filled by the electro-sensitive substance layer through the fluoroscopic portion. When no external power is present, a colorless totem is observed from outside the sensing unit (ie, the N pole is observed). Conversely, when the external power is expanded to the sensing unit, the totem is instantaneously converted into the first color (ie, the S pole is observed), and the first color is usually an external color such as red with a reminding effect. Thus, by changing the color of the totem to form a warning mechanism, and to remind the presence of external power, the outsider is kept away from the external power.

In addition, the present invention further has a substrate disposed on a bottom surface of the sensing unit for forming a base of the sensing unit. Furthermore, the sensing unit is covered with a protective layer, so that the sensing unit is less susceptible to damage by external force. The protective layer is composed of a transparent material so that an outsider can easily observe the change of the sensing unit through the transparent protective layer.

All in all, not all external power is enough to make the induction The magnetic substance of the element changes, and the present invention defines a preset power value. When the external power is greater than the preset power value, the magnetic substance produces a change in the exposed color, thereby forming a warning mechanism.

As described above, the leakage display device according to the present invention may have one or more of the following advantages:

(1) The leakage display device of the present invention can cause a leakage of electricity to be generated by a visualizing device to notify a nearby passerby of leakage.

(2) The leakage display device of the present invention can be installed in a public place to remind children or parents of electric leakage around the lamp post or utility pole, and to improve public safety.

The embodiments of the leakage display device according to the present invention will be described below with reference to the related drawings. For the sake of understanding, the same components in the following embodiments are denoted by the same reference numerals.

First, please refer to FIG. 1 , FIG. 2A and FIG. 2B simultaneously, which are schematic diagrams of the sensing unit of the leakage display device of the present invention, a first use state diagram of the sensing unit of the leakage display device of the present invention, and the present invention. A second usage state diagram of the sensing unit of the leakage display device. As shown in FIG. 1 , FIG. 2A and FIG. 2B , the leakage display device of the present invention comprises a sensing unit 1 having a pattern layer 11 and an electro-sensitive substance layer 12 , and the electro-sensitive substance layer 12 is disposed on The bottom of the pattern layer 11. Wherein, the electro-sensitive substance layer 12 is filled with the electro-sensitive substance 121, and the feeling The electric substance 121 may be a material that reacts with electricity. In the present invention, the magnetic substance 121 is exemplified, and the magnetic substance 121 has a color, but this is merely an example and is not limitative.

In detail, the magnetic substance 121 filled in the electro-sensitive substance layer 12 changes due to an external electric power 4. In other words, when the range applied by the external power 4 is extended to the magnetic substance 121 in the electro-sensitive substance layer 12, the external electric power 4 additionally generates a magnetic force due to the electromagnetic induction described in the amphibious law of Ampere. The magnetic force interacts with the magnetic substance 121 described above, and the reaction may be mutual or mutual exclusion. Therefore, by the reaction, the magnetic substance 121 generates a magnetic transition, thereby causing the originally colored magnetic substance 121 to undergo a change in the exposed color by mutual reaction of magnetic force or mutual exclusion. In other words, if N of the magnetic substance 121 is defined to be extremely colorless, S is a first color 1112. The magnetic substance 121 exchanges the positions of the N pole and the S pole due to the applied magnetic force, and further the exposed color is colorless. (as shown in FIG. 2A, the original N-pole is exposed) becomes the first color 1112 (as shown in FIG. 2B, the S-pole is exposed), that is, the first color 1112 passes through the pattern layer disposed on the electro-sensitive substance layer 12. 11 and revealed.

In summary, the original pattern layer 11 is provided with a totem 111 design, the totem 111 design includes at least one see-through portion 1111, and an external person can see the magnetic substance filled by the electro-sensitive substance layer 12 through the fluoroscopic portion 1111. The color of 121. When no external power 4 is present (as shown in Fig. 2A), a colorless totem 111 (i.e., an N pole is observed) is observed from outside the sensing unit 1. Conversely, when external power 4 When expanding to the sensing unit 1 (as shown in FIG. 2B), the totem 111 is instantaneously converted into a first color 1112 (ie, an S pole is observed), and the first color 1112 is usually a red color with a reminding effect. The color. Thus, by changing the color of the totem 111 to form a warning mechanism, and to remind the presence of external power, the outsider is kept away from the external power 4. The sensing unit 1 can be installed on a floor tile or a tile near a public street lamp or a utility pole, especially a park, and a warning mechanism is used to prevent the pedestrian from inadvertently accidentally touching the leakage area to cause injury, thereby promoting publicity. Safety.

Next, please refer to FIG. 3, which is a schematic diagram of the leakage display device of the present invention. As shown in FIG. 3, the leakage display device of the present invention further comprises a substrate 3 and a protective layer 2. The substrate 3 is disposed on the bottom surface of the sensing unit 1 to form a base of the sensing unit 1. In addition, the protective layer 2 is used to cover the sensing unit 1 so that the sensing unit 1 is less susceptible to damage by external force. The protective layer 2 is composed of a transparent material so that an external person can easily observe the change of the sensing unit 1 through the transparent protective layer 2.

It should be noted that not all of the external power 4 is sufficient to cause the magnetic substance 121 of the sensing unit 1 to change. When there is a small amount of power that is insufficient to invade the human body and expands to the sensing unit, the color of the totem 111 of the sensing unit 1 It will not change. In other words, the present invention defines a preset power value that, when the external power 4 is greater than the preset power value, produces a change in the exposed color of the magnetic substance 121 to form an alert mechanism. The edge is that the magnetic substance 121 of the present invention is matched with the preset The power value is selected to give it better sensitivity.
