Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a lightning rod device, and more particularly, to a lightning rod device that is installed so as to be extendable and retractable so that the lightning rod can be extended to function only when necessary.

[0002]

[Prior Art]

 For example, in large areas such as golf courses, parks, and sports fields, it is common that no lightning rod equipment is installed. Even if it is installed, only fixed lightning rod devices are installed in high-lighting lights, management offices, school buildings, etc., and the protection range is extremely limited. Met.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional configuration has the following problems. As described above, in a wide area such as a golf course, park, or playground, a lightning rod device is not installed due to reasons such as hindering competition or spoiling the aesthetics. There was a high risk that the company was required to improve it.

The present invention has been made on the basis of such points, and its purpose is to provide a beautiful appearance in a large area such as a golf course, a park, or a playground without hindering the competition. It is to provide a lightning rod device that allows the installation of a lightning rod without damaging it.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the lightning rod device according to the present invention is installed in an arbitrary place, and is installed in an arbitrary place, and a lightning rod which is in a contracted state when not functioning and is in an expanded state when functioning, a driving means for expanding and contracting the lightning rod. A lightning strike detector that detects the state of lightning strike and outputs a signal, and whether or not there is a risk of lightning strike based on the signal from the lightning strike detector And a control means for driving the lightning rod to extend the lightning rod.

[0006]

[Action]

 When there is no risk of lightning strike, the lightning rod is in the contracted state. On the other hand, when there is a risk of lightning strike, the control means determines based on the signal from the lightning strike detector and the lightning rod is extended by the driving means. This will prepare for a lightning strike.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. First, as shown in FIGS. 1 and 2, for example, a pit 3 is provided at an arbitrary place of the golf course 1, and a lightning rod 5 is accommodated in the pit 3 in a retractable state. Has been done. The lightning rod 5 is formed by connecting a plurality of metal tubes 7 (for example, carbon steel, austenitic stainless steel, aluminum, etc.), and a lightning rod 9 shown in FIG. Has been. A brush 11 made of austenitic stainless steel is attached below the lightning rod 9, as shown in FIG. A lid 4 is installed in the pit 3 so as to be openable and closable, and when the lightning rod 5 extends, the lid pushing up arm 6 attached to the tip pushes up the lid 4. A drive unit 13 and a control unit 14 are attached below the lightning rod 5. The lightning rod 5 is expanded and contracted by the drive unit 13. The pits 3 and the lightning rods 5 having the above structure are installed at intervals of 99 m, for example, and the height when extended is about 50 m. If the height when stretched is about 30 m, the gap should be about 59 m.

On the other hand, as shown in FIG. 5, the lightning strike detector 15 is arranged at an arbitrary position, and this lightning strike detector 15 is for detecting the electric field disturbance, and its signal is It is input to the reception board 17. The receiving board 17 determines whether or not there is a risk of lightning strike based on the input signal, and outputs a signal to the control unit 14 already described. The control unit 14 extends the lightning rod 5 via the drive unit 13 based on the signal. This prepares for a lightning strike. The arbitrary place may be, for example, a management office.

The operation will be described based on the above configuration. For example, as shown in FIG. 6, in fine weather, there is no thundercloud and the risk of lightning strike is low. In that case, the lightning rod 5 is retracted and stored in the pit 3 as shown in FIG. It is in a broken state. Further, since the lightning rod 5 is in the contracted / retracted state, it does not hinder the competition and does not spoil the aesthetics of the mischief.

Next, as shown in FIG. 7, when the thundercloud 21 starts to be generated and the risk of lightning strike becomes high, the receiving board 17 is detected based on the signal from the lightning strike detector 15. Determines that there is a high risk of lightning strikes. Specifically, when the thundercloud 21 occurs within 15 km, it is determined that the risk of lightning has increased. As a result, a signal is output from the receiving board 17 to the control unit 14, and the lightning rod 5 is extended via the drive unit 13. In other words, the lid 4 of the pit 3 is pushed up, and the lightning rod 5 extends. This is the state shown in FIG. This will prepare for a lightning strike. In addition, in such weather conditions, the competition itself is often stopped, so it does not seriously hinder the competition.

As described above, according to this embodiment, the following effects can be obtained. First, at the golf course, the lightning rod 5 can be installed without any hindrance to the game and without impairing the appearance. This is because the lightning rod 5 is retractably stored in the pit 3, and is normally stored in a retracted state so that it can be extended and functioned only when necessary. Therefore, it is possible to significantly reduce the damage of lightning strikes at a golf course and improve safety.

The present invention is not limited to the above-mentioned one embodiment. Although the golf field has been described as an example in the above-mentioned embodiment, the invention can be similarly applied to other parks, sports fields and the like. The structure of the lightning rod 5 to be expanded and contracted is not limited to that shown in the drawing. In addition, the criteria for determining whether there is a risk of lightning strike is also optional.

[Effect of the device]

 As described in detail above, according to the lightning rod device of the present invention, it is possible to install lightning protection equipment in a golf course, a park, a playground, etc. without hindering the competition and without impairing the appearance. This makes it possible to reduce the damage from lightning strikes at golf courses, parks, playgrounds, etc.
