Description

Technical Field

[0001] The present invention belongs to the technical field of rain enhancement and hail prevention rockets, and particularly relates to a rain enhancement and hail prevention rocket dispenser. Background Art

[0002] Artificial weather modification is one of the important means for meteorological science and technology to prevent and mitigate disasters. Rain enhancement and hail prevention rockets have many advantages such as large catalyst carrying capacity, high nucleation rate, high launch altitude, and easy operation, so they have been rapidly popularized and applied nationwide. Most rain enhancement and hail prevention rocket dispensers adopt the technology of ejecting submunitions to achieve linear and circumferential three-dimensional catalyst dispersion.

[0003] Patent CN 102524004 A provides a hail prevention and rain enhancement body catalyst dispenser, which uses a central delay charge column to ignite the ejection charge of the submunition. As more and more submunitions are ejected, the nozzle for linear dispersion becomes larger and larger, resulting in a large change in the dispersion state and uneven dispersion.

[0004] Patent CN 202890102 U provides a civil hail prevention and rain enhancement rocket catalyst dispenser. The dispenser body, dispenser housing, and nozzle are sequentially connected by threads to form the dispenser. It has a large number of components, complex processing procedures, and cumbersome assembly processes, and at the same time has the problem of uneven dispersion state mentioned above. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems of the existing rain enhancement and hail prevention rocket submunition dispensers, such as a large number of components, complex processing procedures, cumbersome assembly processes, and uneven dispersion state, and to provide a rain enhancement and hail prevention rocket dispenser.

[0006] The technical solution for achieving the purpose of the present invention is: a rain enhancement and hail prevention rocket dispenser, including a sealing cover, a linear catalyst assembly, a dispersion chamber, a catalyst igniter assembly, and a submunition assembly;

[0007] A plurality of linear catalyst assemblies are embedded in the inner wall of the dispersion chamber at intervals along the axis. A plurality of stepped through holes are circumferentially and evenly arranged on the side wall of the dispersion chamber between adjacent linear catalyst assemblies. The through hole with a larger diameter of the stepped through hole is located on the outer surface side of the dispersion chamber, and the submunition assembly is arranged in the through hole with a larger diameter of the stepped through hole; a catalyst igniter assembly is arranged at the bottom of the dispersion chamber, a sealing cover is arranged at the top, a timing controller is arranged in the sealing cover, and a wire is arranged in the dispersion chamber;

[0008] The timing controller outputs a catalyst ignition signal to ignite the wire catalyst assembly at the bottom and the bullet ejection charge in the submunition assembly. The wire catalyst in the wire catalyst assembly burns and linearly disperses the catalyst into the cloud from the through-hole with a smaller diameter in the stepped through-holes of the spreading bin, i.e., the nozzle. The submunition assembly disperses the submunition catalyst in a three-dimensional space. When the catalyst in the wire catalyst assembly at the bottom burns out, the ignition charge of this wire catalyst assembly is ignited, and the ignition charge ignites the catalyst of the adjacent wire catalyst assembly. The above process is repeated until the operation ends.

[0009] Furthermore, the spreading bin is formed by buckling two identical spreading half-bins. When the spreading half-bins are buckled, there is a gap for arranging wires. Stepped parts for socketing with other components are respectively provided at both ends of the spreading half-bins; on one side of the buckling plane of the spreading half-bins, there is a long strip-shaped protrusion, and on the other side, there is a groove, and the width of the long strip-shaped protrusion is smaller than the width of the groove. A plurality of grooves for installing the wire catalyst assembly are provided on the inner wall of the spreading half-bins.

[0010] Furthermore, the catalyst ignition tool assembly includes an ignition seat, a conductive nut, a conductive screw, a gasket, a catalyst ignition tool, a catalyst ignition charge, and a catalyst ignition charge box;

[0011] The ignition seat is a stepped cylinder with cavities at both ends and a partition in the middle. The outer shape of the ignition seat matches the inner shape of the spreading bin. A wire through-hole is opened on the side wall of the bottom cavity. The catalyst ignition charge box and the catalyst ignition charge pressed in the catalyst ignition charge box are placed in the cavity on the other side. A conductive screw through-hole is opened on the middle partition of the ignition seat. The catalyst ignition tool is buried inside the catalyst ignition charge. The conductive screw is provided with a conductive nut, and both the conductive screw and the conductive nut are provided with conductive gaskets.

[0012] Furthermore, the sealing cover is bowl-shaped. The outer shape of the sealing cover adapts to the inner shape of the spreading bin. Two wire through-holes are opened on the side wall of the sealing cover. The two wires are respectively connected to the catalyst ignition end and the engine ignition end of the timing controller. A groove is provided on the outer wall of the sealing cover, and a sealing ring is arranged in the groove to achieve the seal between the sealing cover and the spreading bin and prevent the wire catalyst in the wire catalyst assembly from burning and causing the fire to spread and burn the timing controller and wires inside the sealing cover.

[0013] Furthermore, the engine ignition end of the timing controller is connected to the engine ignition tool through a wire that successively passes through the wire through-hole on the side wall of the sealing cover, the gap reserved when the two spreading half-bins are buckled, and the wire through-hole of the ignition seat, forming an engine ignition circuit;

[0014] The catalyst ignition end of the timing controller is connected to the gasket, the conductive nut, and the conductive screw through a wire that successively passes through the wire through-hole on the side wall of the sealing cover, the gap reserved when the spreading half-bins are buckled, and the wire through-hole of the ignition seat, and is conducted to the catalyst ignition tool, forming a catalyst ignition circuit.

[0015] Further, the wire catalytic assembly includes a wire catalytic ignition cartridge, wire catalytic ignition charge, wire catalytic cartridge case, wire catalytic sealing ring, wire catalyst, and wire catalytic cartridge cover;

[0016] The wire catalytic cartridge case is a stepped cylinder with cavities at both ends and a partition in the middle. There is a fire transfer through-hole on the middle partition; the cavity with a smaller diameter is located at the upper part and contains the wire catalytic ignition cartridge and the wire catalytic ignition charge pressed in the wire catalytic ignition cartridge, and the wire catalyst is installed in the cavity with a larger diameter through the wire catalytic cartridge cover.

[0017] Further, one end of the wire catalytic cartridge case with a larger diameter cavity is assembled in the groove of the spreading half bin, and grooves are provided on the outer wall surface of the wire catalytic cartridge case and wire catalytic sealing rings are installed in the grooves to prevent the flame from spreading and prematurely igniting the next wire catalytic assembly when the current wire catalytic assembly is working;

[0018] An annular step is provided on the outer wall surface of the end of the wire catalytic cartridge case where it is assembled with the wire catalytic cartridge cover, and the wire catalytic cartridge cover is bonded to the wire catalytic cartridge case and positioned at the stepped part on the outer surface of the wire catalytic cartridge case.

[0019] Further, the submunition assembly includes a submunition case, submunition sealing ring, submunition catalyst, and submunition propelling charge;

[0020] The submunition case is a cylinder with one end closed and a cavity inside. The submunition catalyst is pressed in the cavity inside the submunition case. The shape of the assembled submunition catalyst is a cylinder with a cavity at one end, and the submunition propelling charge is pressed in the cavity.

[0021] Further, a groove is provided on the outer surface of the spreading half bin where the stepped through-hole is located, and a protrusion matching the groove on the outer surface of the spreading half bin is provided at the closed end of the submunition case. After the submunition assembly is assembled, it does not protrude beyond the outer circular surface of the spreading bin;

[0022] A groove is provided on the outer side wall surface of the submunition case to place the submunition sealing ring to ensure good sealing of the spreading bin.

[0023] A method for spreading the catalyst using the above-mentioned spreader is as follows:

[0024] Before the rain enhancement and hail suppression rocket is launched, the timing controller enters the working state. According to the local temperature, air pressure, altitude, and cloud height at the launch site, and simultaneously using time and height information, the timing controller is wirelessly bound to set the engine ignition time and the catalyst ignition time;

[0025] The timing controller outputs an engine ignition signal. After receiving the signal, the engine igniter ignites the engine grain to provide flight power for the rocket;

[0026] The timing controller outputs a catalyst ignition signal at a predetermined time. The catalyst igniter receives the signal and ignites, simultaneously lighting the wire catalyst and the submunition propellant. The wire catalyst burns and linearly disperses the catalyst into the cloud from the nozzle of the spreading half-chamber. After the submunition assembly is ejected under the action of the propellant gas generated by the submunition propellant, the submunition propellant ignites the submunition catalyst, and the submunition catalyst is dispersed in a three-dimensional space;

[0027] After the wire catalyst burns for a predetermined time, it burns out and ignites the wire catalytic ignition charge at the same time. The wire catalytic ignition charge ignites the next group of submunition propellants and the next wire catalyst;

[0028] Repeat the above process until all the wire catalysts have burned out and all the submunition assemblies have been ejected, and the working process ends.

[0029] Compared with the prior art, the remarkable advantages of the present invention are as follows:

[0030] For the rain enhancement and hail prevention rocket spreader provided by the present invention, the spreading half-chamber is formed by molding. Two identical spreading half-chambers are buckled to form a spreading chamber, and only one set of molds is required, so the cost is relatively low. At the same time, the spreading half-chamber has the functions of submunition ejection and linear dispersion of the catalyst with its own nozzle, reducing the number of parts. Moreover, the design of the spreading half-chamber simplifies the assembly difficulty of the wire catalytic assembly, with a simple structure and good processability.

[0031] For the rain enhancement and hail prevention rocket spreader provided by the present invention, there is only one fire transmission through-hole connecting between adjacent two wire catalytic assemblies, which maximally ensures that the spreading states of each wire catalytic assembly are almost the same. At the same time, it avoids setting loop wires separately within each wire catalytic assembly, with a simple structure and a uniform spreading state.

[0032] For the rain enhancement and hail prevention rocket spreader provided by the present invention, there is a groove for placing wires on the buckling plane of the spreading half-chamber. After the two spreading half-chambers are buckled, the wires are hidden inside the spreading chamber, which is not easy to cause the wires to burn due to short circuit, and has no impact on the assembly process of other parts. At the same time, in the present invention, conductive screws, conductive nuts, and gaskets are used to conduct the loop, with good sealing performance and no mutual influence among each ignition loop.

After the wire catalyst 11 burns at a certain burning rate for a predetermined time and burns out, it ignites the wire catalytic ignition charge 8. The wire catalytic ignition charge 8 ignites the next group of submunition ejection charges 23 and the next wire catalyst 11, repeating the above process until all the wire catalysts 11 are burned out and all the submunition assemblies 5 are ejected, and the working process of the spreading bin 3 ends.
