Description

Lightning-triggering wire laying device and lightning-triggering wire laying method

[0001] The present disclosure relates to a lightning catching wire laying device and a lightning catching wire laying method.

[0002] A known method of triggering lightning is to attach a metal wire to a rocket, launch the rocket, and pull the wire up into the sky to trigger a lightning strike (Non-Patent Document 1). It has also been proposed to trigger a lightning strike by pulling up the wire with a drone.

[0004] To increase the success rate of rocket-triggered lightning, the impedance of the wire being pulled up must be low. However, wire made of low-impedance material is prone to breaking, so wire with high impedance (such as piano wire) is used.

[0005] Increasing the cross-sectional area of ​​the wire would lower the impedance of the wire and increase the success rate of lightning triggering, but this would make the wire heavier and more difficult to pull up with a rocket. In particular, if a thick wire is wound on a bobbin, the load on the rocket when pulling it up would be greater.

[0006] One possible method is to place the wires on the ground without winding them around a bobbin, but this creates the problem of the wires getting tangled in the wind or getting caught on plants or stones.

[0007] The present disclosure has been made in consideration of the above, and aims to improve the success rate of rocket-triggered lightning.

[0008] A lightning wire laying device according to one aspect of the present disclosure is a lightning wire laying device for laying a lightning wire, and is equipped with a drum for winding up and storing the lightning wire, a storage facility for storing sand, an outlet for discharging the sand from the storage facility, and wheels for movement, the drum moving in conjunction with the wheels, and as the lightning wire laying device moves, the lightning wire is pulled out of the drum and placed on the ground, and the outlet working in conjunction with the wheels discharges the sand and covers the lightning wire placed on the ground with the sand.

[0009] A method for laying a lightning attracting wire according to one aspect of the present disclosure involves laying a lightning attracting wire along the ground and covering the wire with sand.

[0010] According to the present disclosure, the success rate of rocket-triggered lightning can be improved.

[0011] Fig. 1 is a diagram showing an example of a lightning attracting wire laying method, Fig. 2 is a diagram showing an example of the configuration of a induction wire laying device, and Fig. 3 is a diagram showing an example of the configuration of a induction wire laying device.

[0012] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0013] [Method for laying a lightning attracting wire] With reference to FIG. 1, an example of a method for laying a lightning attracting wire according to this embodiment will be described.

[0014] In the method for laying a lightning wire in this embodiment, a lightning wire 11 attached to a lightning rocket 10 is laid along the ground, and sand 20 is then covered on top of the wire 11. In Figure 1, the entire wire 11 is covered with sand 20 to hold it down, but it is also possible to cover only points of the wire 11 with sand 20 to hold it down, rather than the entire wire 11.

[0015] The wires 11 are laid on the ground so that they do not tangle when being pulled up. In FIG. 1, the wires 11 are laid on the ground in a serpentine manner, but this is not limiting. For example, the wires 11 may be arranged in a spiral shape. It is preferable to lay the wires 11 so that the tension on the wires 11 is reduced when the rocket 10 pulls them up.

[0016] It is desirable that the ground on which the wire 11 is placed is free of grass, trees, stones, and other objects that could get caught on the wire 11 when it is pulled up.

[0017] One end of the wire 11 is connected to the ground. For example, the wire 11 is tied to a stake driven into the ground. The other end of the wire 11 may be connected to a power storage facility so that lightning energy can be reused.

[0018] A piano wire or copper wire with a diameter of about 0.2 mm can be used for the wire 11. To increase the success rate of lightning triggering, it is advisable to use a wire 11 with a large cross-sectional area. The length of the wire 11 is set to about several tens of meters to several hundreds of meters.

[0019] The wire 11 may be covered with sand 20 over the entire length thereof, or only a portion of the wire 11. The wire 11 may be covered with sand 20 continuously or intermittently. It is not necessary to cover the wire 11 with sand 20 until it is completely invisible. It is sufficient to cover the wire 11 with sand 20 to the extent that it will not move significantly in the wind.

[0020] When triggering lightning with a rocket, wire 11 is attached to rocket 10, and rocket 10 is launched toward a thundercloud. When rocket 10 rises, wire 11 is pulled up, but since wire 11 is only covered with sand 20, there is almost no tension when wire 11 is pulled up. When rocket 10 is launched at high speed, the tip of rocket 10 or wire 11 causes leader discharge, inducing lightning.

[0021] Instead of rocket 10, a drone may be attached to wire 11.

[0022] [Induction Wire Laying Apparatus] An example of the configuration of a lightning induction wire laying apparatus according to this embodiment will be described with reference to FIG.

[0023] The wire laying device 100 shown in FIG. 2 includes front wheels 110, rear wheels 120, a wire drum 130, a sand storage 140, and a sand scraper 150.

[0024] The wire drum 130 winds and stores the wire 11. The wire drum 130 is connected to the front wheels 110 or the shafts of the front wheels 110 by a belt, chain, gear, or the like. The front wheels 110 and the wire drum 130 rotate in unison, thereby pulling out the wire 11 according to the travel distance of the wire-laying device 100. The wire 11 is pulled out between the two rear wheels 120 directly below the wire-laying device 100 and placed on the ground, where it is laid along the travel path of the wire-laying device 100.

[0025] The sand storage 140 stores sand 20 to be placed over the wire 11 .

[0026] The sand rake 150 is a discharge port that discharges the sand 20 stored in the sand storage 140, and rakes out an appropriate amount of sand 20 as the wire-laying device 100 moves, covering the wire 11 with the sand 20. The sand rake 150 has blades around the periphery of a cylinder, and rakes out the sand 20 as the cylinder rotates. The sand rake 150 is connected to the rear wheel 120 or the shaft of the rear wheel 120 by a belt, chain, gear, or the like. The rear wheel 120 and the sand rake 150 rotate in tandem, causing the sand 20 to be rake out.

[0027] The sand scraper 150 is not limited to the above, but may also be a screw conveyor with spirally arranged blades attached to an axis, or an opening and closing gate in which the lid of the sand storage facility 140 opens and closes according to the rotation of the rear wheel 120.

[0028] The sand scraper 150 is attached behind the point where the wire 11 drawn out from the wire drum 130 contacts the ground so that the wire 11 can be covered with sand 20 after being placed on the ground.

[0029] Either the front wheels 110 or the rear wheels 120 may be linked to the wire drum 130 and the sand scraper 150. That is, the front wheels 110 may be connected to the sand scraper 150, or the rear wheels 120 may be connected to the wire drum 130. The wire drum 130 may also be connected to the sand scraper 150.

[0030] The wire laying device 100 may be fitted with sensors to ensure that the correct length of wire 11 and the correct amount of sand 20 are laid simultaneously.

[0031] The wire-laying device 100 may be equipped with a handle and operated by a person, or may be operated by remote control from a remote location. Alternatively, the wire-laying device 100 may be equipped with a GPS or the like and operate automatically.

[0032] An example of the configuration of a modified lightning wire-laying device is shown in Figure 3. The wire-laying device 100 shown in the figure is equipped with a tank 160 containing water 21 behind a sand storage facility 140, and pours the water 21 from the tank 160 onto the sand 20 that covers the wire 11. By pouring an appropriate amount of water 21 onto the sand 20, the sand 20 becomes moist and sticky, preventing it from being blown away by the wind.

[0033] As explained above, in the lightning attracting wire laying method of this embodiment, the wire 11 attached to the rocket 10 is laid along the ground and then covered with sand 20. By laying the wire 11 along the ground, little tension is applied when pulling up the wire 11, so the cross-sectional area of ​​the wire can be increased, reducing impedance and improving the success rate of attracting lightning. In addition, the sand 20 prevents the wire 11 laid on the ground from being blown away by the wind, so the wires 11 do not become tangled or get caught on grass, trees, stones, etc.

[0034] The wire-laying device 100 of this embodiment includes a wire drum 130 that winds and stores the wire 11, a sand storage 140 that stores sand 20, and a sand scraper 150 that covers the pulled-out wire 11 with sand 20. The front wheels 110 or rear wheels 120 are linked to the wire drum 130 and sand scraper 150, and as the wire-laying device 100 moves, the wire 11 is pulled out from the wire drum 130 and placed on the ground, and the sand scraper 150 scrapes out sand and covers the wire 11 placed on the ground with sand 20. In this way, the wire 11 can be pulled out along the movement trajectory of the wire-laying device 100, and the wire 11 can be covered with sand 20.
