Rain-increasing rockets are one of the important means for meteorological departments to artificially modify the weather, especially in Northeast China, where droughts occur frequently every spring and spring plowing is seriously affected. Artificial rainfall can effectively solve part of the drought and increase production and harvest for the majority of farmers make a great contribution. Rain-enhancing rocket launch systems are mainly divided into vehicle-mounted and fixed-type. Droughts frequently occur in Northeast China, and the affected areas are relatively large. Joint rainfall enhancement operations are often carried out in various regions. Therefore, the more convenient vehicle-mounted rainfall enhancement rocket launch system is popular, but at the same time, the lightning protection safety of the vehicle-mounted launcher is inevitably introduced. Hidden dangers, rainfall enhancement operations must be carried out in cloudy and rainy weather, and most of the work sites are relatively open or mountainous places with high lightning protection safety risks, which pose a certain threat to the safety of rainfall enhancement operators and equipment.

The damage caused by lightning strikes to the launching operation of rain-increasing rockets is mainly in the following two ways: one is the personal casualties and equipment damage caused by direct lightning strikes.

Its main protective measures include launch tube 1, lifting device 2, down conductor 4 and vertical grounding body 5, etc. Second, provide lightning induction protection for weak current working systems such as terminal control boxes. The protection measures mainly include lightning induction shielding, equipotential connection and grounding of the terminal control box and control lines.

Direct lightning protection design:

Considering that the rocket launcher is made of steel metal material as a whole, it is a good conductor of lightning current, and the launcher can completely cover the rain-increasing rocket, which can provide good external protection for the rain-increasing rocket when it is struck by lightning, so the lightning rod is no longer designed separately , but the rocket launcher itself is used as the lightning receptor. The launcher is equipped with an equipotential connection line, two downconductors 4 and two vertical grounding bodies 5. The launch tube 1 is connected to the backing plate 10 through the equipotential connection line. When the launcher is struck by lightning, the downconductor 4 leads the lightning current underground through the vertical grounding body 5 .

The shell box body of the launch terminal control box 7 is made of metal, so that it forms a "Faraday circle", so the "Faraday circle" can be directly used to achieve a good lightning protection effect, and the launch terminal control box 7 utilizes the "Faraday circle" lightning protection device The shunting effect is obvious. The launch terminal control box 7 supports 8 are multi-purpose. When in use, the supports 8 are embedded in the ground and used as a simple grounding body. Due to a large number of grounding, the lightning current on each downconductor 4 is greatly reduced. Good external lightning protection effect.

The front end of the armored control line 6 is connected to the launch tube 1, and the rear end is connected to the launch terminal control box 7. The metal sheath of the armored control line 6 is connected to the outer casing of the launch tube 1 and the launch terminal control box 7 respectively. The control box 7 and the support 8 are connected with an equipotential connection line, and the support 8 is multi-purpose, and the support 8 pins are inserted into the earth to be used as a simple grounding body, thereby achieving a good lightning protection effect.

When the vehicle-mounted rain-increasing rocket launch system is directly struck by lightning, due to the good electrical conductivity of the launcher, it will play a better role in lightning connection. The launch tube 1 adopts a cage structure, and the rain-increasing rocket is inside the launcher. , can be effectively protected, and the lightning current will flow into the ground through the launch tube 1, the equipotential connection line, the down conductor 4 and the vertical grounding body 5, thereby effectively ensuring the safety of the rocket ammunition and the launch system. When lightning strikes buildings, trees and other facilities near the vehicle-mounted rain-increasing rocket launch system, due to the short distance, lightning induction will be generated on the launch system and terminal control equipment, and a high-voltage lightning current will be generated instantly, which is extremely It is easy to burn the equipment or generate control signal confusion, which will lead to the failure of the launch system or accidents, but this launch system can effectively avoid the above problems. When an induced lightning strike occurs, due to the skin effect of lightning, the lightning current will concentrate on the surface of the object or line. , when the armored control line 6 senses the lightning current, the lightning current will flow into the ground through the metal sheath of the control line through the launch frame down conductor 4 or the launch terminal control box 7 support 8, effectively protecting the line safety, when the launch terminal control After the box 7 senses the lightning current, the lightning current concentrates on the surface of the control box shell, and will flow through the equipotential connection line between the launch terminal control box 7 and the support 8 and finally flow into the ground through the support 8, so as to achieve direct contact with the launch system. All-round protection from lightning to induced lightning.

The device protects the vehicle-mounted rocket launcher against lightning through the launch tube 1, down conductor 4, vertical grounding body 5, launch terminal control box 7 metal shell and bracket 8, which effectively saves manpower and material resources and protects the human figure. workers and equipment. When a lightning strike occurs, the lightning current along the launching frame will cause the voltage to rise rapidly, reaching hundreds or even thousands of volts. Because the lightning protection device is used to introduce the lightning into the ground, most of the transient energy can be transferred, but at this time due to The top of the launcher is higher than the surrounding objects, and its tip concentrates the electric charge of the opposite sign in the cloud. If the lightning occurs between the cloud and the ground, the discharge current mainly flows into the earth through the launcher and the down conductor 4, so Operators and launch systems are protected.

The above are the preferred embodiments of the present invention, and all changes made according to the technical solution of the present invention, when the functional effect produced does not exceed the scope of the technical solution of the present invention, all belong to the protection scope of the present invention.
