[0020] Limiting columns 5 are fixed on both sides of the top of the frame platform 1, and a passive gear 10 is rotatably inserted in the limiting column 5. A driving gear 11 is meshed on the surface of the passive gear 10, and a moving rod 9 is fixed on one side of the driving gear 11, and a motor 6 is installed on one side of the driving gear 11.

[0021] The gun body subsystem includes a shock wave generator 8, a detonation tank, a catalyst box 12, an igniter assembly 7 and a steering motor group. The gun body subsystem is a device for generating gas gun shock waves, strong sound waves, high-speed airflow and artificial ice nuclei.

[0022] The electronic control subsystem includes a remote control terminal, a control cabinet 3 and a pressure transmitter, and is composed of gas gun operation control, pipeline monitoring, gas mixing ignition and gun barrel shooting direction adjustment.

[0023] The gas source subsystem includes fuel gas, compressed air, oil-water separator and control valve group. The gas source subsystem is a gas cannon fuel gas and compressed air storage and generation equipment, providing dry and stable mixed fuel gas for gas cannon explosion. There is no need to apply for airspace when the system is operating, and there are no special requirements for the operating location and operating area environment. There is no need to consider safety factors such as safe firing range. The function of the oil-water separator is to separate oil droplets and water droplets in compressed air to ensure the normal operation of the equipment and air quality. The control valve group plays a vital role in the rain-making and hail-prevention air cannon. It is mainly responsible for controlling the flow and release of fuel gas and compressed air to ensure that the air cannon can work according to the predetermined procedure.

[0024] The power subsystem includes a diesel engine, a generator and a battery. The power subsystem is composed of a diesel engine, a generator and a battery to provide electrical energy for the operation of various components of the equipment. Different components require different power supply systems to meet different needs. It can also adapt to the demand for electricity in different situations and improve the practicality of the equipment.

[0025] The trailer subsystem includes a braking and steering mechanism, a torsion axle assembly and a frame platform 1. The trailer subsystem is a mobile transfer platform for the above subsystems to ensure the safe and rapid transfer of products. A crawler 2 is installed at the bottom of the frame platform 1. The crawler 2 is connected to the trailer subsystem. The crawler design allows the equipment to be moved in a small range through a remote control terminal during operation. It has stronger adaptability and can cope with more complex working conditions. It has strong climbing ability and supports mobile operations in a small range.

[0026] According to the attached Figure 1 As shown, a control cabinet 3 is fixed on the top of the frame platform 1, and the control cabinet 3 is provided with multiple groups. Door panels 4 are hinged on the surfaces of the multiple groups of the control cabinets 3. An air source subsystem, a power subsystem and a trailer subsystem are provided in the control cabinet 3. An igniter assembly, a steering motor assembly and a pressure transmitter are provided in the control cabinet 3. Different systems are classified and installed to improve the efficiency of maintenance and reduce unnecessary searching time. The whole system adopts a modular design. Failures in different modules can be quickly solved by replacing the modules, which improves the efficiency of replacement and simplifies the difficulty of replacement and maintenance.

[0027] According to the attached Figure 3 As shown, the passive gears 10 are symmetrically arranged in two groups, and an igniter assembly 7 is fixed in the middle of the two groups of passive gears 10, and a shock wave generator 8 is installed in the igniter assembly 7, so that resources can be effectively utilized and unnecessary waste can be avoided. It also provides greater flexibility, so that the air cannon can be adjusted according to real-time meteorological data and needs to achieve the best operating effect.

[0028] According to the attached Figure 4 As shown, the gun body subsystem is connected to the gas source subsystem and the power subsystem through pipelines and lines, a catalyst flows in the pipeline, and the catalyst and the igniter assembly are respectively connected to the gas source subsystem and the power subsystem. The detonation tank is installed inside the shock wave generator 8. When operating, the gas, catalyst and compressed air are filled into the tank in a certain proportion, and then the mixed gas in the tank is ignited to produce deflagration. This deflagration process will generate violent shock waves in the detonation tank, and these shock waves are then modulated and their pressure peaks are strengthened, and finally ejected from the gas gun barrel together with the catalyst to achieve the operational effects of preventing hail and reducing disasters, increasing rain and resisting drought.

[0029] The performance characteristics of this equipment: 02 is 4.1×2.1×2.7m, with a total weight of 4500kg. The detonation energy of each equipment is ≥60KPa, the detonation shock wave speed is 850m / s, the sound wave intensity is 120dB, the catalyst (each detonation) is adjustable from 0.05 to 0.2, the detonation time interval is adjustable from 6 to 10 seconds, the detonation rate is ≥95%, the remote control distance is ≮600m, the continuous working time is ≮3 hours, the life span is ≮6 years, the power consumption is <10kw, and the ambient temperature is -30℃~60℃.

[0030] The rain-increasing and hail-prevention air cannon in this application has completed the test and experimental verification of the sound wave effect on cloud particle condensation, and compared and analyzed the natural dissipation process of simulated water mist in the cloud chamber and the dissipation process affected by sound waves. Before the sound source was turned on, the particle number concentration, liquid water content and droplet size distribution range measured by the droplet spectrometer were basically the same. After 10 minutes, it was found that the droplet particle number concentration and liquid water content under the influence of the sound source were significantly smaller than the values ​​in the natural state, and the particle size spectrum distribution was obviously biased towards the small particle end. At the same time, due to the decrease in the droplet particle number concentration and the sedimentation of larger droplet particles, the visibility in the cloud chamber quickly improved. In summary, sound waves have a certain promoting effect on the condensation and collision of water vapor particles, which verifies the acoustic condensation (collision) theory.

[0031] In the present application, the above-mentioned sound waves propagate in the air, causing the air in the field to perform orderly reciprocating motion, causing the air particles to compress or expand periodically, causing the particles in the air to vibrate and displace, and the effects produced are mainly the following: Artificial rainfall enhancement: Through the shock wave generated by the gas explosion of the equipment, the rainfall enhancement catalyst (cold cloud or warm cloud) is transported to the target cloud body, increasing the condensation nuclei in the target cloud body (cold cloud method). As the density of ice crystals increases, the cloud droplets quickly condense or collide and grow into raindrops and fall down; or through the use of hygroscopic catalysts (warm cloud method), the cloud droplet concentration is reduced, the cloud droplet spectrum is widened, and it is transformed from continental cloud to oceanic cloud, which promotes gravity collision and ice crystal formation, and can quickly grow into large cloud droplets of more than tens of microns in the cloud to form precipitation.

[0032] Hail disaster prevention: By continuously influencing the target area, the natural airflow structure of cumulus clouds that forms hail is destroyed, the growth of hail embryos is inhibited, and a large number of small hail (hail embryos) in the operating area are forced to fall in advance before they grow larger, melt into raindrops or small ice particles and fall to the ground, thereby achieving the effect of hail prevention.

[0033] Defogging and haze reduction: Through the continuous impact of shock waves on the target area, the structure of the atmospheric inversion layer is destroyed, especially the vertical structure of the strong updraft area. By creating impact airflow, the surrounding air flow is driven to form air convection. Under the action of vertical air convection, the haze air in the inversion layer close to the ground can break through the inversion resistance and go to high altitudes, so as to promote the full exchange of near-ground air and high-altitude air, effectively inhibit the formation of heavy haze or reduce the haze concentration; according to different use environments and conditions, industrial waste gas can also be quickly discharged to high altitudes outside the inversion layer through the energy of shock waves.

[0034] The components used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0035] Working principle: When in use, the device is transported to a suitable location, and then moved to a specific location through the crawler 2 and the trailer subsystem. The motor 6 is started by remote control according to the use requirements, and the output end of the motor 6 drives the driving gear 11 and the moving rod 9 to rotate, and then the driving gear 11 rotates to drive the driven gear 10 to rotate, and finally the use angle of the igniter assembly 7 and the shock wave generator 8 is adjusted; Next, the power subsystem provides a power source for the equipment, and the gas source subsystem is started by remote control to mix the fuel gas, catalyst and compressed air, and the oil-water separator starts to work. Then the shock wave generator 8 mixes the fuel gas, catalyst and compressed air through the igniter assembly 7 and explodes. The igniter assembly and the detonation tank generate shock waves to the shock wave generator 8. These shock waves are emitted into the air through the shock wave generator 8, continuously affecting the target area, forming a strong airflow disturbance, thereby increasing rain and preventing hail.

[0036] The above is the entire working principle of the present invention.
