Description

Self-luminous aviation hazard indicator device {FLIGHT HINDRANCE-SHOWING BALL APPARATUS}

The present invention relates to an aviation obstruction indicator installed on a power transmission-processing branch line, and more specifically, to an aviation obstruction indicator device that is equipped to emit its own light.

On the overhead lines of transmission towers, aviation obstruction indicators are installed at regular intervals to prevent approaching aircraft and ensure visibility during the day.

The minimum diameter of an aviation obstacle indicator is 60cm, and according to related laws, if the diameter of the indicator sphere is 0.6m to 0.8m, it is spaced at 30m intervals, if the diameter of the indicator sphere is 0.8m to 1.3m, it is spaced at 35m intervals, and if the diameter of the indicator sphere is 1.3m or more, it is spaced at 40m or more. It is prescribed to be installed.

These aviation obstruction indicators, which are installed on overhead transmission line branch lines, are operated by setting installation targets, methods, and management standards to protect the lives and property of air traffic service users by ensuring flight safety during the day, but are simply used as daytime warning signs. It is only used, but there are currently no relevant standards or methods for identification at night.

Transmission towers over 60m in height are equipped with aviation obstruction lights to facilitate identification at night, but since transmission lines do not have identification devices, all aircraft crashes actually occur on power lines. Examples of such accidents include the US military Apache helicopter on November 23, 2015, and the US military Chinook helicopter on March 25, 2011.

In particular, in the case of transmission lines crossing valleys near military bases, it is difficult to identify transmission lines at night, so there is a risk of a major accident due to contact with an aircraft (helicopter).

Meanwhile, due to the revision of the design standards for overhead transmission steel towers, the standard span of transmission steel towers was increased from 300m to 400m for 154kV and from 350m to 450m for 345kV, and due to difficulties in securing land due to civil complaints during transmission line construction, the gap between steel towers was increased. As the span increases, the installation of aviation obstruction indicators on overhead branch lines is increasing.

In addition, as the size of transmission towers has increased due to the increase in ultra-high voltage transmission systems such as 765kV and the construction of multi-circuit towers with four or more lines, the height of transmission lines above the ground is increasing, making night flights of aircraft (helicopters) flying near transmission lines more dangerous. I'm doing it.

Additionally, transmission lines change color to black after a certain period of time after construction, making it more difficult to identify power lines at night.

For this reason, in the event of a collision failure between a power transmission line and an aircraft (helicopter), it causes enormous damage to power supply, life, and property.

The matters described in the above background technology are intended to aid understanding of the background of the invention, and may include matters that are not prior art already known to those skilled in the art in the field to which this technology belongs.

In order to fully understand the present invention, its operational advantages, and the objectives achieved by practicing the present invention, reference should be made to the accompanying drawings illustrating preferred embodiments of the present invention and the contents described in the accompanying drawings.

In describing preferred embodiments of the present invention, known techniques or repetitive descriptions that may unnecessarily obscure the gist of the present invention will be reduced or omitted.

Figure 1 shows the aviation obstruction indicator device of the present invention installed and applied to an overhead branch line.

A plurality of aviation obstruction indicator devices 100 according to an embodiment of the present invention are installed at intervals on the overhead power transmission line (1) to enable the transmission line to be identified during the day and night.

Figure 2 shows an aviation obstacle indicator device according to an embodiment of the present invention, and Figure 3 is a projection image of the aviation obstacle indicator device of Figure 2.

An aviation obstacle indicator device according to an embodiment of the present invention for performing this role will be described with reference to FIGS. 2 and 3.

The aviation obstruction indicator device 100 according to an embodiment of the present invention is manufactured separately into an upper case (10a) and a lower case (10b) for ease of installation to form an exterior, and an interior formed by the upper and lower cases. A piezoelectric element power generation unit 40, a converter 50, a power supply unit 60, and a battery 70 are provided in the space, and an LED light source 80 is provided to protrude from the outer surface of the upper and lower cases.

The case consisting of the upper case 10a and the lower case 10b is preferably spherical for stability, installation, etc., and for this purpose, each case is manufactured in a hemispherical shape.

The upper case 10a and the lower case 10b are provided with an appropriate number of LED mounting parts 12, so that the LED light source 80 mounted on the LED mounting part 12 emits light so that aircraft such as aircraft can recognize the power transmission line even at night. Let it happen.

In the example, the LED mounting portion 12 in the upper case 10a and the lower case 10b is located at the center of the hemispherical outer surface, and is composed of a flat or curved plate that is recessed rather than the outer surface of the case for mounting the LED on the hemispherical case. do.

A transparent LED cover 30 is formed on the LED mounting portion 12 to protect the LED light source 80 mounted thereon and to allow light from the LED light source 80 to pass through.

In addition, the overhead wire 1 can pass through the upper case 10a and the lower case 10b, and a cable cover 11 to protect the overhead wire 1 is formed to protrude from the side.

An insulating member 20 is formed inside the cable cover 11 protruding from the side to avoid electrical contact with the overhead wire 1 and protect the structure within the case.

Meanwhile, the aviation obstruction indicator device of the present invention is constantly installed on overhead wires and is subject to a lot of environmental influences. In addition, as it includes an internal electrical component, the durability of the case becomes an important factor.

Therefore, the upper case (10a) and lower case (10b) of the present invention are made of high-strength engineering plastic material. In other words, by applying high-strength LUSEP super engineering plastic, which is molded by adding 30% G.F (Glass Fiber) and UV reducer to the PPS series, it has super heat resistance and flame retardancy that can withstand fire even over 200℃, and is more than twice as strong as steel. It represents the characteristics.

In addition, the LED cover has an IP65 rating, which strengthens waterproofing and eliminates the cause of failure of the LED light source 80.

Furthermore, the LED cover 30 is preferably applied in a structure that increases light transparency and prevents the pinhole phenomenon (a phenomenon in which the internal light source is visible).

That is, for this purpose, the light transmittance and refractive index can be strengthened by finely embossing the surface.

In addition, the LED color reproducibility is excellent, preventing glare and maximizing energy efficiency. Impact resistance can also be achieved at a level of 250 times that of glass and 50 times that of acrylic, and it exhibits excellent weather resistance and heat resistance. do.

Additionally, UV surface treatment is applied to the LED cover 30 to prevent yellowing (color change caused by ultraviolet rays).

The piezoelectric element power generation unit 40, converter 50, power supply unit 60, and battery 70 provided inside the case cause the LED light source 80 to emit light by power generation or charge the battery 70, This is a configuration to control this.

Figure 4 is a conceptual diagram of the power supply of the aviation obstacle indicator device of the present invention, Figure 5 shows a piezoelectric element power generation unit applied to the aviation obstacle indicator device of the present invention, and Figure 6 is a piezoelectric element of Figure 5. It shows the power generation concept of the power generation unit.

Hereinafter, with reference to Figures 4 to 6, we will look at the internal configuration of the aviation obstacle indicator device according to an embodiment of the present invention.

The aviation hazard indicator 100 according to an embodiment of the present invention produces power by the piezoelectric element power generation unit 40.

The aviation obstruction indicator 100 is affected by wind power as it is provided on a transmission line at a certain height from the ground.

Due to the influence of such wind power, the aviation hazard indicator device vibrates, and the piezoelectric element power generation unit 40 applied to the aviation hazard indicator device of the present invention is used to convert such vibration energy into electrical energy.

The electricity produced by the piezoelectric element power generation unit 40 is converted into direct current power by a converter 50 and transmitted to the power supply unit 60, and the power supply unit 60 is electrically connected to the LED light source 80. ) operates to cause the LED light source 80 to emit light or to charge the battery 70 with power. In addition, the power supply unit 60 supplies power stored in the battery 70 to the LED light source 80 as needed, thereby controlling the LED light source 80 to operate at all times.

Here, the LED light source 80 may be used for oscillating at a low intensity of 32 cd or more. It is possible to adopt an SMD (Surface Mount Device) type chip LED that has more than 1/5 the weather resistance and durability of existing D-type LED products compared to D-type LED products.

In the piezoelectric element power generation unit 40, a piezoelectric ceramic 41 capable of producing power by the piezoelectric effect is coupled to the leaf spring 43 in order to convert mechanical energy generated by wind power into electric energy, and the leaf spring 43 As (43) vibrates, electricity generated by the piezoelectric ceramic (41) is supplied to the power supply unit (60) through the lead wire (44) connected thereto.

It is preferable that a plurality of these piezoelectric ceramics 41 are provided for power production, but the piezoelectric element power generation unit 40 of the present invention is a type in which the piezoelectric ceramics 41 are coupled to the leaf spring 43, and the leaf spring ( Considering the maximum operating radius of 43), it is more preferable to have four configurations spaced radially by 90 degrees to prevent collision between leaf springs 43, and this configuration of four leaf springs is divided into multiple units. Configurable.

In addition, by allowing the weight bodies 42 to be coupled to the ends of the leaf springs 43, the weight bodies 42 exert the effect of generating greater vibration energy.

In this way, the electricity generated by the piezoelectric element power generation unit 40 is converted by the converter 50, and charged to the battery 70 by the power supply unit 60, or used to emit light by the LED light source 80 mounted on the PCB. I order it.

The circuit configuration for power supply by the power supply unit 60 is shown in FIG. 7.

The AC power generated by the piezoelectric ceramic 41 is divided through C1, draws power corresponding to AC 18V 1mA ~ 50mA, and converts the AC power into DC power through bridge diodes D1 ~ D4, then Vin or Charge. It is charged through the resistor connected to the pin.

In addition, the converter can be implemented to enable independent control by connecting each piezoelectric ceramic individually, and by adding a device that can detect and reset errors to the converter, it can prevent overheating due to overcharging of the battery, detect abnormalities, The device can be operated by blocking overcurrent, etc., and blocking chattering by adding a triple RS flip circuit to the SMPS (Switching mode Power Supply) at the oscillator stage in case the converter does not detect it.

And, when the illuminance level falls below the set level through the CDS (Photoconductive Cells) illuminance sensor, which is a sensor whose resistance changes depending on the amount of light, the DC power is smoothed through the condenser C3, and then the DC 4V power is stably obtained from the regulator and divided. Used as input power for the circuit.

The divider IC is divided by the incoming clock and blinks the high-brightness LED to emit light.

At this time, the switch between Charge and Vin2 turns on only when it enters Relax Mode (a state in which the circuit consumes very little power).

In this way, when the LED light source 80 is driven, charging is performed only when harvested energy remains. In other words, it is charged during the day, and when the illuminance falls below a certain level according to the illuminance sensor, the LED light source 80 emits light, and while it is emitting light, when it enters Relax mode, it is operated to be recharged.

In order to stabilize the charging and power supply, self-protection functions such as battery charging power limitation, overdischarge protection circuit, output power distribution circuit, and lightning surge protection circuit can be built in.

Meanwhile, it is desirable that the internal structure of this case is solidly insulated and firmly fixed inside in the form of a pack.

However, when an abnormality occurs in the charging power supply, noise and surge may be mixed into the incoming line of the main power supply, causing circuit damage.

To achieve this, it is desirable to reinforce the noise filter for the wire and add circuit reinforcement for constant voltage and constant current and a circuit configuration for self-protection (ARM system) at the circuit inlet.

As seen above, the aviation hazard indicator device according to the present invention uses power by converting vibration caused by wind power into electric energy, and uses the charged power to achieve constant self-luminescence and stable supply of power. The safety of aircraft and power transmission lines can be prevented through efficient use.

Although the present invention as described above has been described with reference to the illustrative drawings, it is not limited to the described embodiments, and it is common knowledge in the field of this technology that various modifications and changes can be made without departing from the spirit and scope of the present invention. It is self-evident to those who have it. Accordingly, such modifications or variations should be considered to fall within the scope of the patent claims of the present invention, and the scope of rights of the present invention should be interpreted based on the appended claims.
