Description
Technical Field
The invention relates to the field of artificial rainfall enhancement equipment, in particular to a passive digital rainfall enhancement and hail suppression rocket with accurate timing, safety and reliability.
Background
The artificial influence weather is based on the research result of cloud and fog precipitation physics, in particular to the artificial rainfall test taking accumulated clouds as the object. At present, hail suppression and rain enhancement operation tools at home and abroad are subjected to different development periods from earth cannons, earth rockets to antiaircraft cannons, novel rockets and the like. The hail suppression and rain enhancement operation of earth cannons and antiaircraft cannons mainly converts chemical heat energy into kinetic energy through one-time work of an explosive device in a cannonball, overcomes the gravity effect and emits substances influencing the weather into the atmosphere, and often cannot achieve the expected effect due to the fact that the shooting height of the cannonball is low; the soil rocket and the novel rocket adopt a rocket launching mechanism, the rocket is to be launched to a preset high point through the delay action of the delay ignition device, and the delay ignition device acts to enable the rocket to continuously act for a certain time after the rocket completes the parachute opening function, so that substances influencing weather can be well scattered in a preset atmosphere, and a good hail-preventing and rain-increasing effect is achieved. However, the problems of high misfire rate and misfire rate of the delay fuse, short delay, poor delay precision and the like generally exist in the prior art.
The existing rain-increasing hail-suppression rocket bomb mainly comprises a rocket body, a delay tube, an umbrella cabin, an umbrella opening device, a fixed-explosion delay tube detonator and a functional part. The delay tube is arranged at the front end of the engine, the parachute and the parachute opening device are fixed on the delay tube 2 and are arranged in the parachute cabin, meanwhile, the fixed explosion delay tube and the detonator are inserted into the detonator seat at the front end of the parachute cabin, the fixed explosion delay tube is inserted into the round hole at the front end of the delay tube through the parachute opening device, and the function part is connected to the parachute cabin. The delay tube is used for delaying fire transfer for a preset time to the fixed explosion delay tube, and simultaneously, the parachute opening device is excited, the parachute cabin is pushed away, the parachute cabin and the functional part are pushed forwards, and the parachute is opened. The detonator is detonated after the fixed-detonation delay tube is used for a preset time, so that the functional part is detonated directly, and the purpose of catalyst spreading is achieved.
The disadvantages of the rocket projectile in use are as follows: 1. the delay time is accurate and the operation is reliable; because the delay devices in the rocket projectile are all initiating explosive device delay tubes, the delay time is difficult to be accurate and the operation is unreliable due to the influence of raw materials, equipment, processing technology, assembly flow, production environment and the like in the production process. 2. After the rocket is lifted off, the fixed explosion delay tube works in the high-altitude and high-negative-pressure environment, so that fire is easily cut off and flameout is easily caused, and the work failures of the parachute opening device, the functional part and the like are caused. 3. The problem of rocket frame explosion. In the production process of the rocket projectile, most parts are industrial initiating explosive device parts, so that the problem of quality of part of initiating explosive devices is avoided, the rocket projectile is retained in the rocket rail after being launched, the preset delay time is reached, and the rocket energy part works to explode the rocket rail. 4. The existing rocket projectile is easily illegally launched in modes of pressurizing and the like.
