Description

Technical Field

[0001] The invention relates to the technical field of human shadow rockets, in particular to a multi-channel delayed ignition device for hail-proof and rain-enhancing rockets. Background Art

[0002] Artificial rainfall enhancement is a method of using seeding technology on certain types of cloud systems and storm systems to appropriately increase or redistribute precipitation. It is a means for humans to transform and utilize nature. For example, catalysts such as silver iodide and dry ice are sent into supercooled parts of clouds using tools such as airplanes, rockets, cannons, combustion furnaces, and flares to increase ice crystals and condensation nuclei in the clouds, causing more water vapor to form raindrops and fall to the ground. For warm clouds, hygroscopic catalysts (such as salt, calcium chloride, calcium oxide, urea, ammonium nitrate, etc.) are seeded into the clouds to cause cloud droplets to grow into raindrops and fall, thereby increasing precipitation. In addition, rockets, antiaircraft guns, and flares can also be used to generate artificial rainfall. When bombs explode in the clouds, shock waves are generated, which can accelerate the collision and merging process between cloud droplets, causing them to merge and grow into raindrops and fall down, thus increasing rainfall. Since rockets are launched at a high altitude, they are more suitable for areas with lower altitudes or in spring and autumn when the zero-degree layer is higher. Therefore, rocket operation systems are widely used in artificial rainmaking operations. When rockets are used to spread artificial ice nuclei in the operating area, the average height of the local monthly average isotherm of -6 to -12°C during the operating period should be counted in advance as a reference for the rocket flame spreading altitude layer. At this time, the latent heat effect should also be considered. The temperature in the cloud (updraft area) is generally slightly higher than the ambient temperature.

[0003] The launching methods of rain-enhancing rockets can be divided into the following types: plane shooting: when the horizontal scale of cumuliform clouds is large, the vertical scale is small, and the rising air currents in the clouds are weak, plane shooting is used. This method carries the silver iodide particles evenly to the optimal catalytic height in the cloud layer, so that the catalyst can act on a larger horizontal plane to achieve the maximum rain-enhancing effect; trapezoidal shooting: when the vertical scale of cumuliform clouds is large, and the rising air currents in the clouds are strong, trapezoidal shooting is used. This three-dimensional shooting method uses different shooting angles and different directions to bring the silver iodide particles to different heights in the cloud layer, so that the catalyst can act on a larger vertical plane to achieve the maximum rain-enhancing effect.

[0004] However, the existing processing equipment has the following shortcomings:

[0005] In daily use, it is found that most of the existing equipment uses a single-channel ignition device such as CN209459516U to ignite the rocket, and the equipment cannot delay the ignition time during the ignition process. Because the equipment cannot delay, the operability of the equipment is reduced, resulting in poor ignition performance of the equipment.

[0006] Therefore, we propose a multi-channel delayed ignition device for hail-proof and rain-enhancing rockets to solve the above-mentioned problems. Summary of the invention
