1 is a view schematically showing a transmission tower protection facility according to the present invention, FIG. 2 is a perspective view showing a wind direction switch for operating the mass spray nozzle shown in FIG. 1, and FIG. 3 is shown along the line A-A in FIG. It is an exploded cross section.

Referring to Figure 1, basically, the transmission tower 10 is installed on the base 20 protruding above the ground (S). The base 20 is constructed by pouring concrete, the lower part is buried into the ground (S), and the upper part protrudes above the ground.

As shown in FIGS. 1 and 2, the transmission tower protection facility 100 according to the present invention pumps water from the storage tank 110 and the water storage tank 110 buried in the underground G, in some cases around the transmission tower 10. The spraying nozzle 170 and the mass spraying nozzle 190 that spray the It includes a wind direction switch (200).

First, the water storage tank 110 is a place that receives rainwater during the rainy season or in rainy weather, and a water collecting port 120 that receives rainwater and flows it to the water storage tank 110 is installed on the ground (S) around the power transmission tower 10 .

The catchment port 120 is located as low as possible than the transmission tower 10, and receives rainwater naturally flowing down by digging a furrow around the transmission tower 10 or by the slope of the mountain ridge. A large mesh strainer 122 is covered with a lid to filter out large foreign substances such as stones in the water collecting port 120 .

In addition, the guide pipe 130 is connected to flow the rainwater received from the water collecting port 120 to the water storage tank 110 . At this time, a small mesh sieve 132 is mounted between the water collecting port 120 and the guide tube 130 to filter out small foreign substances such as soil once again. In addition, the guide tube 130 is formed to be inclined so that it naturally flows into the water storage tank 110 .

Meanwhile, a discharge pipe 140 for discharging water is connected to the water storage tank 110 . A pump 160 is installed in the discharge pipe 140 to generate water pressure to be sprayed while raising the water in the water storage tank 110 .

The discharge pipe 140 is connected to the valve controller 150 that is automatically opened and closed by an input signal. As the valve controller 150, a conventional solenoid valve is used. In this case, the valve controller 150 is preferably installed inside or on the upper surface of the base 20 , and may be installed outside the base 20 .

The valve controller 150 has a structure capable of distributing water in at least five directions. That is, the first direction is connected to the entire watering nozzle 170 evenly installed on all four sides of the base 20 , and the rest are connected to the mass watering nozzles 190 installed in four directions of the base 20 , respectively. In other words, the valve controller 150 has two valves, one controls the water spray nozzle 170 , and the other controls the mass spray nozzle 190 . In this case, the spray nozzle 170 and the mass spray nozzle 190 may be installed by extending the pipe so as to be positioned at a predetermined height of the power transmission tower 10 .

In order to input an operation signal to the valve controller 150 formed in this way, a plurality of fire detection sensors 180 are installed around the power transmission tower 10 . That is, when the fire detection sensor 180 detects a surrounding fire, it inputs a signal to the valve controller 150 to operate the water spray nozzle 170 to spray water around the power transmission tower 10 like a sprinkler.

In addition, a wind direction switch 200 is installed around the power transmission tower 10 in order to input another operation signal to the valve controller 150 . The wind direction switch 200 calculates the current wind direction and sprays a large amount of water in the wind direction to suppress the progress of the forest fire or to extinguish the forest fire. The wind direction switch 200 calculates the wind direction to operate only one of the mass sprinkling nozzles 190 .

The wind direction switch 200 is integrally coupled to the upper portion of the vertical rod 210 and the vertical rod 210 having a structure that is vertically erected and rotated as shown in FIGS. 2 and 3 and rotates according to the direction of the wind. It is composed of a direction meter 220 of the, an outer cap 230 surrounding the lower outer side of the vertical rod 210 , and four electrodes 231 formed on the inner circumferential surface of the outer cap 230 .

In such a wind direction switch 200, the vertical rod 210 is rotated by the wind vane 220, and any one of the four electrodes is contacted according to the rotation of the vertical rod 210 to inform the current wind direction signal. At this time, four electrodes 231 are formed in a circle at equal intervals on the inner circumferential surface of the outer cap 230 , and a gap is formed between the electrodes 231 . And each electrode 231 is formed to be spaced apart up and down, and a connection terminal 211 is formed on the lower outer surface of the vertical rod 210 in order to conduct any one of the electrodes 231 spaced apart from the top and bottom. .

Looking at the relationship between the weather vane 220, the electrode 231, and the connection terminal 211 in more detail, when the weather vane 220 points to the east, the connection terminal 211 is a mass installed in the east with respect to the transmission tower 10. The spray nozzle 190 is transmitted to any one electrode 231 and the valve controller 150 connected to the east to be sprayed.

In this way, the mass spraying by the wind direction switch 200 is normally operated after the spraying nozzle 170 is operated by the fire detection sensor 180 .

As described above, in the transmission tower protection facility according to the present invention, once a forest fire is detected by the fire detection sensor 180, water is immediately sprayed from a large amount of water spray nozzles 170 installed around the transmission tower 10 to Wet grass and soil to prevent access to wildfires.

And, in the state in which the fire detection sensor 170 is operated, the wind direction switch 200 calculates the current wind direction and mass-saturates the predicted path of the forest fire, thereby suppressing the approach of the forest fire, as well as extinguishing the forest fire there will be

Here, since the wildfire proceeds in the windward direction, mass sprinkling in the windward direction in the transmission tower 10 is the correct countermeasure.

And a camera unit 700 is installed around the power transmission tower 10 in order to input another operation signal to the valve controller 150 .

The camera unit 700 may photograph a surrounding image of the power transmission tower 10 , analyze the photographed image to determine whether a forest fire has occurred, and may input an operation signal to the valve controller 150 .

For example, the camera unit 700 may collect a plurality of wildfire occurrence images, extract a feature value, and build an image analysis model by repeatedly learning through a deep neural network. In this case, the camera unit 700 may extract a feature value from image data using the Librosa library, and may adopt a fully connected neural network model having three hidden layers as a deep neural network.

As such, the camera unit 700 can build an image analysis model that can determine whether a forest fire has occurred by extracting a wildfire occurrence feature value according to image data through deep learning, and the surrounding image of the power transmission tower 10 captured in real time By inputting data into an image analysis model, it is possible to determine whether a wildfire has occurred.
