Description

Technical Field

[0001] The utility model belongs to the technical field of artificial weather influencing equipment, and in particular relates to a rain-increasing and hail-preventing rocket spreader with controllable spreading sequence. Background Art

[0002] The rain-enhancing and hail-prevention rocket is a type of ammunition used for artificial weather modification operations. The spreader is its warhead, which is filled with catalysts. The catalyst is launched into the cloud layer through a rocket launcher. After the catalyst column is ignited, the high temperature is used to sublimate the effective components of the catalyst into aerosol particles as artificial crystal nuclei to achieve the purpose of artificial weather modification. Rocket spreaders can be divided into line spreaders and body spreaders according to the method of spreading catalysts. The body spreader has the advantages of large catalyst spreading area and high catalytic efficiency compared with line spreader. The common feature of the above two spreading methods is that after the catalyst is started, it will continue to spread and cannot be paused until the catalyst column burns out. When the cloud thickness is limited, or the cloud layer that needs to be catalyzed is a layered cloud, that is, the cloud thickness is discontinuous and there are layers, the continuous spreading operation method will not be able to spread in the target cloud layer in a concentrated or layered manner, resulting in a waste of catalysts and a significant reduction in the operation effect. Therefore, it is necessary to design a rain-enhancing and hail-prevention rocket spreader that can controllably spread catalysts. That is, after knowing the height and thickness of the target cloud layer, the spreader can perform the task of spreading catalysts in the target cloud layer according to the set parameters to achieve precise spreading.

[0003] Through literature search of the prior art, it is found that in recent years, there are few patent documents on rain-enhancing and hail-preventing rocket spreaders. The public information related to the present application mainly includes: 1. A hail-preventing and rain-enhancing body catalyst spreader (patent number: 201010608722.7); 2. A hail-preventing and rain-enhancing rocket (patent number: 201110031765.8); 3. A civilian hail-preventing and rain-enhancing rocket catalyst spreader (patent number: 201220594803.0); 4. A layered structure rain-enhancing and hail-preventing rocket spreader (patent number: 201520849874.4); 5. An artificial rain-enhancing and hail-preventing rocket that can spread catalyst multiple times (patent number: 201410588450.7).

[0004] Patent 1 provides a hail prevention and rain enhancement body-spreading catalyst spreader. In order to solve the problem that the traditional line-spreading spreader only spreads the catalyst along the rocket's flight trajectory, has a small spreading range and poor operating effect, it adopts body-spreading technology and uses the series and parallel structure of explosive bullets to form a three-dimensional spreading effect and improve the operating effect. However, the starting time of the spreading is fixed and cannot be adjusted according to the actual situation of the cloud layer. Patents 2 and 3 provide a civilian hail prevention and rain enhancement rocket catalyst spreader, which adopts the form of cluster bomb loading, realizes the body-spreading function of combining line spreading with spatial three-dimensional spreading, and uses a delayed fuse to control the timing of spreading. The starting time of spreading can be set in advance according to the actual meteorological conditions at the operation site. The spatial spreading range of the catalyst is increased and the operation effect is enhanced, but the spreading is continuous after the spreading is started and cannot be spread in batches according to the cloud conditions; Patent 4 provides a layered structure rain-making and hail-prevention rocket spreader, based on the cluster bomb spreading design, the cover body is made of engineering plastics, the processing technology is simplified, and the material utilization rate is high. This technical solution is to improve the processing efficiency of the spreader shell, and no method for controlling the starting time of spreading is proposed; Patent 5 provides an artificial rain-making and hail-prevention rocket that can spread catalysts multiple times. It can use a single rocket for multiple spreading operations, improve spreading efficiency, save operating costs, and the spreading time and number of spreading times are controllable, but the catalyst is spread by line spreading, and the spreading efficiency is low.

[0005] None of the above patents proposes a method or measure for achieving controllable body seeding on the target cloud layer. The utility model patent introduces a rain-enhancing and hail-prevention rocket seeding device with controllable seeding timing. During rain-enhancing and hail-prevention operations, each catalytic module can be controlled according to the set seeding time, and the catalyst can be seeded in the target cloud layer according to the time requirement, thereby achieving the effect of precise seeding of the catalyst, which has great engineering value.

DETAILED DESCRIPTION

[0018] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1 As shown, the utility model is a rain-enhancing and hail-prevention rocket spreader with controllable spreading timing, comprising a hood 1, a connector 2, a projectile 3 and a control cabin 7. The hood 1 and the connector 2 are connected by threads on the connector, and the connector 2, the projectile 3 and the control cabin 7 are connected by bolts 8; the projectile 3 is composed of a plurality of catalytic modules that are buckled together layer by layer and tightly connected by bolts 8, and an electronic fuse 9 is arranged inside the control cabin.

[0021] like Figure 2 As shown, the catalytic module is a cylinder, including an upper cover 4, a bullet 5, a lower cover 6 and an electric ignition element 10.

[0022] like Figure 3As shown, an ignition hole 11 is provided at the center of the upper cover 4. The ignition hole 11 is a through hole for embedding the electric ignition element 10. Assembly through holes 12 are provided at equal intervals outward from the center of the circle. A groove is provided between the ignition hole 11 and any one of the assembly through holes 12, which is the same as the wire for fixing the electric ignition element 10. The wire of the electric ignition element 10 passes through each layer of the catalytic module from the assembly through hole 12 and is connected to the electronic fuse 9 at the end of the spreader; the bolt 8 passes through each layer of the catalytic module through the assembly through hole 12 to achieve a tight connection of each layer of the catalytic module; a bullet hole 13 is provided between the two assembly through holes 12, and a fire transfer channel 14 is radially provided along the ignition hole 11 and is connected to the bullet hole 13, so as to ensure that the ignition energy of the electric ignition element 10 can be reliably released to the surface of the bullet 5. The electronic fuse 9 can be set according to the sowing time before firing, and the electric ignition element 10 is an electric ignition product. After firing, the electronic fuse 9 can output single-channel or multi-channel ignition energy according to the set time, and the bullet 5 is fired after the electric ignition element 10 is ignited. The inner side of the bullet hole 13 is provided with a groove for embedding the flange of the bullet shell 15, so that the bullet 5 can be embedded in the upper cover 4 and riveted without falling out.

[0023] The projectile 3 is formed by buckling 8 catalytic modules, and the circumferential surface of the catalytic module is provided with 6 bullet holes. In this embodiment, a rain-increasing and hail-prevention rocket spreader with controllable spreading sequence is provided with a total of 48 bullet holes. The electric ignition element 10 is an electric ignition head, which can be controlled by the electronic fuse 9 to output ignition energy to ignite the bullet 5. The bullet shell 15 is made of polyethylene resin and can be ignited by the catalyst 18, and no large debris is formed after the operation.

[0024] When working, the spreader of the utility model is assembled into a rain-increasing and hail-preventing rocket. When artificial weather modification is performed, the target cloud height and thickness data are input into the rocket launch system. The launch system converts the cloud data into 8 spreading times and sets them into the electronic fuse 9. After the rocket is launched, the electronic fuse 9 inputs ignition energy to the electric ignition element 10 of a single catalytic module according to the set time. After the electric ignition element 10 is ignited, the ignition energy simultaneously ignites the ignition powder 17 of 6 bullets 5 through the fire transmission channel 14. The ignition powder 17 pushes the bullet 5 back and ejects it from the bullet hole. The bullet 5 relies on inertia and the reverse propulsion ability of the ignition powder 17 to fly along the axial direction and radial direction of the spreader at the same time. During the flight, the catalyst 18 continues to burn and releases artificial crystal nuclei to form a three-dimensional spreading channel to achieve the purpose of rain-increasing and hail-preventing. The spreader continues to fly, and the electronic fuse 9 inputs ignition energy to the electric ignition element 10 of the specified catalytic module according to the set next spreading time until all eight layers of catalytic modules are spread.

The bullet shell 15 is a cylindrical shell with an open end, and a flange is provided on the upper end surface to ensure that the bullet is loaded into the bullet hole of the upper cover 4 and the lower cover 6 without falling out. The reinforcing cap 16 can fix the ignition powder 17 and the catalyst 18 to ensure that the powder does not fall off the open end of the bullet shell 15, and a round hole is provided in the center of the reinforcing cap 16 to ensure that the ignition energy of the electric ignition element 10 can reliably ignite the ignition powder 17.
