Description

Technical Field

[0001] The utility model relates to the technical field of rocket rack safety assistance, in particular to a safety assistance device for artificial weather modification fixed rocket rack. Background Art

[0002] The equipment for artificial weather modification operations mainly includes antiaircraft guns, rockets, smoke stoves, and air cannons. Rockets are divided into vehicle-mounted rockets and fixed rockets. Fixed rockets are equipment installed at fixed ground sites for artificial weather modification operations. By launching rockets and spreading catalysts, the physical and chemical processes of the local atmosphere are artificially affected to achieve the effect of artificial hail prevention and rain increase. At present, rockets are widely used due to their advantages such as long range, wide impact range, large amount of catalyst, and no influence from bad weather. However, in actual applications, when launching rockets, the fixed rocket rack will move due to the influence of the recoil of the launch, and sometimes even tilt, and the shooting direction may also change. Long-term operation will have a certain impact on the safety of the operation and the stability of the equipment.

[0003] At present, fixed rocket launchers mostly use threaded adjustable support feet to press against the ground, so that the universal wheels of the launcher are lifted off the ground to achieve support and fixation. However, this fixing method still has the following problems in use:

[0004] Although this fixing method increases the friction with the ground through the support legs, the large recoil during rocket launch will still cause the launch pad to move slowly. After a long period of launch, the launch pad will have a large deviation, affecting the launch effect and safety. Utility Model Content
