Description

Technical Field

[0001] The utility model relates to the technical field of forest lightning protection, in particular to a forest lightning fire defense system. Background Art

[0002] The forest lightning fire defense system realizes real-time monitoring, early warning and protection of lightning events. This system usually includes a lightning early warning system, an intelligent meteorological monitoring station, an online lightning current monitoring system, and other related regulatory platforms and acquisition monitoring hardware. The lightning early warning system collects various environmental data in real time through a sensor network arranged in the forest, such as temperature and humidity, wind speed, wind direction, rainfall, etc., and sends the data to the data center for analysis through wireless transmission technology. These sensors can detect lightning discharges in the atmosphere, including lightning between clouds and the ground, and collect data such as the time, location, and energy of lightning events. The system will also use satellite remote sensing technology and geographic information systems to achieve comprehensive coverage and precise positioning of forest areas. Through comparative analysis of historical data and real-time data, the system can accurately identify abnormal meteorological conditions and potential risk areas that may cause forest fires caused by lightning.

[0003] In addition, the forest lightning fire defense system also includes hardware facilities such as lightning towers, lightning tower foundations, artificial grounding devices, and grounding modules. These facilities work together with the lightning early warning system to form an all-round, three-dimensional lightning safety intelligent protection system.

[0004] However, the lightning protection systems used in the existing technology for forest lightning fire defense are mostly protected by lightning poles, lightning pole foundations, artificial grounding devices, and grounding modules. In a lightning environment, the current is connected to the lightning object through a clamp-type joint through the lightning pole, and then the current is introduced into the underground through the grounding system to eliminate the impact of lightning on the lightning object. However, the lightning pole attracts the current mostly by being higher than the protected target and being located on the top of the protected target. The protection range is relatively limited, and it is difficult to be effectively applied to forest lightning fire prevention. In view of this, we propose a forest lightning fire defense system. Utility Model Content

The lightning poles can attract electric current by being higher than the protected target and being arranged on the top of the protected target. The scope of protection is relatively limited, and it is difficult to be effectively applied to the technical problem of forest lightning fire prevention.

[0013] Preferably, the protection radius of the lightning-termination tower is ten times or more of the height difference between the lightning-termination tower 101 and the protected target, and the protection angle of the lightning-termination tower is greater than or equal to 86°.

[0014] Preferably, the dissipated current of the lightning current recorder is greater than 10 mA, and the maximum detection voltage of the lightning current recorder reaches 700 KV.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model generates plasma through the natural environment atmospheric electric field and thundercloud induction, and the plasma forms a high-concentration upward divergent ion flow inside the passive strong ionization plasma lightning arrester 103, thereby neutralizing the charge between the cloud and the ground, changing the electric field potential of the thundercloud, and blocking the formation and development of lightning leaders by reducing the electric potential between the cloud and the ground, actively preventing the occurrence of lightning strikes, thereby more effectively protecting the target object from lightning damage, improving the protection range for the target object, and can be efficiently applied to forest lightning fire prevention.

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0021] Example 1: A forest lightning fire protection system, see Figure 1 , including a non-flash-type lightning protection unit 1, a lightning strike data monitoring unit 2 and a grounding discharge unit 3;

[0022] Further, to improve the scope of protection for the target object, see Figure 1The non-flash-connected lightning protection unit 1 includes a lightning pole tower 101 arranged in the forest to achieve the lightning induction action during thunderstorm weather. A lightning pole tower foundation 102 is arranged at the bottom of the lightning pole tower 101, and the lightning pole tower foundation 102 is arranged on the ground. A passive strong ionization plasma lightning arrester 103 is arranged on the lightning pole tower 101. The protection radius of the lightning pole tower 101 is ten times or more of the height difference between the lightning pole tower 101 and the protected target, and the protection angle of the lightning pole tower 101 is greater than or equal to 86°, so as to change the electric field potential of the thundercloud during thunderstorm weather. The non-flash-connected lightning protection unit 1 is connected to the lightning strike data monitoring unit 2 to achieve the induction action. The lightning detection action after the lightning strike, the lightning data monitoring unit 2 is connected to the ground discharge unit 3 to realize the release of lightning electric energy to the earth after the lightning strike, and plasma is generated by the natural environment atmospheric electric field and thundercloud induction. The plasma forms a high-concentration upward divergent ion flow inside the passive strong ionization plasma lightning arrester 103, thereby neutralizing the charge between the cloud and the ground, changing the electric field potential of the thundercloud, and blocking the formation and development of the lightning leader by reducing the electric potential between the cloud and the ground, actively preventing the occurrence of lightning strikes, thereby more effectively protecting the target object from lightning damage, and improving the protection range for the target object. It can be efficiently applied to forest lightning fire prevention.

[0023] Furthermore, in order to facilitate the statistical analysis of the lightning protection data of the forest and to facilitate the optimization of the density of lightning protection equipment in the forest, see Figure 1 The lightning data monitoring unit 2 includes a lightning warning device 201 and a lightning current recorder 202. The dissipated current of the lightning current recorder 202 is greater than 10mA, and the maximum detection voltage of the lightning current recorder 202 reaches 700KV.

The lightning current recorder 202 is connected to the lightning recording service. The lightning strike record service module 203 is connected to the device self-check report module 204 to realize the recording and uploading of lightning strike data. The lightning warning device 201 warns of the occurrence of lightning, and the lightning current recorder 202 detects the current during lightning strike. The detected data is recorded by the lightning strike record service module 203 and uploaded by the device self-check report module 204 at the same time, so as to facilitate the statistics of the forest's lightning protection data, thereby manually optimizing the layout density of the lightning protection equipment in the forest.
