Description
Technical Field
The invention relates to the technical field of artificial precipitation, in particular to an artificial precipitation device, a control method and a control device.
Background
At present, the principle of artificial precipitation is to influence the micro-physical process of cloud layers by scattering catalysts (such as silver iodide, dry ice and the like), so that the cloud layers which cannot naturally precipitate are excited to precipitate under a certain condition, or the cloud layers which can naturally precipitate are enabled to improve the precipitation efficiency. At present, the artificial precipitation catalysis operation mode mainly comprises the following steps: the method comprises the steps of spreading a catalyst by a ground launching antiaircraft gun or a rocket, spreading the catalyst by an airplane, carrying the catalyst by a balloon, arranging a silver iodide combustion furnace on the ground, operating a smoke furnace by artificially influencing weather and the like.
The catalyst spreading mode using ground launching antiaircraft gun or rocket as carrier is: exploding the cannonball in the cloud, and burning the carried silver iodide into a smoke agent to be scattered in the cloud; the rocket burns the silver iodide agent after reaching the cloud height, and the silver iodide agent is spread along with the smoke drawing along the flight process. The mode requires the equipping of vehicle-mounted shell or rocket launching equipment, belongs to the field of initiating explosive devices, is limited by the security level when in use, and is difficult to use in the artificial precipitation task or scientific research experiment of the general level; and equipment and material cost are higher, and the operation process is noisy, and if the rocket falls, the life and property safety on the ground can be influenced if the parachute cannot be opened in time. The rainfall area is limited by the air route, the operation points can not be established according to the needs, only few operation sites can be arranged, and the effect and timeliness of increasing rain and snow are difficult to ensure. When manual precipitation operation is carried out, time and space are limited, the range is not far, and remote precipitation operation cannot be carried out; with the prosperous development of air traffic, the airspace is increasingly tense and increasingly difficult to repeat, the airspace repeated in each rain-increasing operation is only 5min, sometimes only 2-3 min, and even many times, no operation airspace exists. The conflict between the operation time and the busy airspace causes difficulty in airspace repetition and often misses the optimal operation time; rocket and ammunition transportation and ordinary storage require more manpower and material resources.
The airplane carrying the spreading equipment is used for directly spreading the catalyst to a preset position in the cloud. The mode has large investment of fixed assets and high operation cost, the cost of one flight usually needs hundreds of thousands of units to millions of units, and the mode is restricted by factors such as flight conditions, airplane performance, airspace and the like, and cannot be applied in the weather of strong convection in order to ensure the flight safety.
The balloon carries a catalyst, silver iodide smoke bars are fixed on the buoyancy balloon, and smoke agents are continuously burnt and scattered in the ascending process of the balloon, but the ascending path of the balloon is influenced by airflow, so that the uncertainty is high, the proper part of the cloud body cannot be ensured, and the selection of a throwing point is difficult; the balloon is not monitored at all after being put in, and operators cannot check whether the putting is effective or not.
The operation mode of arranging the combustion furnace on the ground is to ignite a catalyst smoke bar or solution to generate a large amount of smoke agent which is conveyed into a target high cloud layer by virtue of ascending air flow. The operation mode requires the naturally formed continuous ascending airflow, is mainly suitable for mountainous areas which are easy to form terrain clouds and provide ascending airflow on windward sides, and has obvious regional limitation.
Rainfall is accomplished by means of a weather modification device, which generally comprises an ignition control system and a smoke furnace chamber, wherein a smoke pipe frame and a smoke pipe are arranged in the smoke furnace chamber, and the smoke pipe is provided with a rainfall enhancement catalyst grain. The working principle is as follows: in a specific region with specific meteorological conditions of updraft, a smoke tube in a smoke furnace chamber is ignited through an ignition control system, so that the rain-increasing catalyst explosive column in the smoke tube is combusted to generate a catalyst smoke agent, and finally the catalyst smoke agent in the smoke furnace chamber is diffused into the air through the suction force of a chimney and is lifted to a target-height cloud layer through the updraft. The catalyst smoke agent enters the air, so that the moisture absorption crystal nucleus in the air cloud can be increased, the water content is increased, and the moisture absorption crystal nucleus is changed into raindrops through collision, so that the effect of artificial precipitation is achieved. The ground silver iodide smoke furnace ignites silver iodide smoke strips installed in the smoke furnace through remote control, and the ascending air flow is used as a carrier to enter a target high cloud layer for catalysis, so that the ground silver iodide smoke furnace is mainly suitable for mountainous areas which are easy to form topographic clouds and provided with ascending air flow on windward sides, and has obvious geographical limitation.

Wherein, a heating unit is arranged in the heat preservation air storage tank 11; the heating unit is used for heating the air in the heat-preservation air storage tank to at least a preset temperature.
The flue gas mixing chamber 13 is communicated with the heat-preservation gas storage tank 11 through the heat-preservation communicating pipeline 12, and catalyst particles are arranged in the flue gas mixing chamber 13; the gas directional output unit 14 is vertically arranged at the upper part of the flue gas mixing chamber 13 and is communicated with the flue gas mixing chamber, and the upper part of the gas directional output unit 14 is provided with an opening for leading out gas.
Specifically, a heating unit is installed in the heat-preservation air storage tank 11, and air in the heat-preservation air storage tank 11 is heated at least to a preset temperature through the heating unit. The preset temperature refers to the temperature which is required to be reached when the air in the heat-preservation air storage tank 11 enters the flue gas mixing chamber 13 through the heat-preservation communication pipeline 12 and rises to a cloud layer with a target height for artificial precipitation through the gas directional output unit 14. In the heat preservation gas holder 11, the steam in the air with the preset temperature is to be separated, and the steam generated due to the temperature difference change is prevented from influencing the performance of the catalyst particles in the flue gas blending chamber 13 when the air with the preset temperature is conveyed to the flue gas blending chamber 13 through the heat preservation communicating pipeline.
The catalyst particles disposed in the flue gas blending chamber 13 may be catalyst particles generated by the catalyst in the flue gas blending chamber 13, or may be catalyst particles stored in the flue gas blending chamber 13 in advance. The catalyst particles in the flue gas blending chamber 13 can also be obtained by delivering the generated catalyst particles to the flue gas blending chamber 13 through an external catalyst particle generating device.
The flue gas mixing chamber 13 is communicated with the heat-preservation air storage tank 11 through a heat-preservation communication pipeline 12, so that air reaching a preset temperature in the heat-preservation air storage tank 11 can flow into the flue gas mixing chamber 13. In the air flowing process, the heat preservation communication pipeline 12 can ensure that the temperature of the air with the preset temperature is kept unchanged. In the flue gas mixing chamber 13, due to the high-speed movement of the gas molecules, the catalyst particles are fully mixed with the entering air with the preset temperature, and the air with the preset temperature enters the outside air through the gas directional output unit 14.
In the working state, the flue gas mixing chamber 13 has no other openings through which the air flow can pass except for the pipe orifice connected with the heat-insulating communicating pipe 12, so as to ensure that the flue gas mixing chamber 13 has good air tightness.
Because the temperature of the air with the preset temperature is high and the density of the air is high, the air enters the outside air through the gas directional output unit 14 and then continues to flow upwards and enters a target height cloud layer capable of carrying out artificial precipitation, and the physical characteristics of particles in the target height cloud layer are changed by the carried catalyst particles so as to excite precipitation. In the case of artificial precipitation, the catalyst can be a general silver iodide catalyst, and the silver iodide catalyst is made into particles and arranged in the flue gas mixing chamber 13. In particular, other different catalysts, such as dry ice or liquid nitrogen, can also be used for scientific research or special needs.
In this embodiment, the catalyst particles in the flue gas blending chamber are carried by the air reaching a predetermined temperature and enter a cloud layer of a target height where artificial precipitation can be performed, thereby exciting precipitation. The device is not limited by regions, can be arranged at any place, weakens the leading action of the traditional topographic wind into the pointing action and the auxiliary action, and widens the topographic application range of the artificial precipitation device. The preset temperature air can reach the target height cloud layer and the catalyst particles are scattered on the target height cloud layer, so that the dosage of the catalyst particles entering the target height cloud layer is ensured, the catalytic efficiency is improved, and the cost of artificial precipitation is reduced. Meanwhile, various devices used by the system are not dangerous, so that the safety coefficient of the system is improved.

The control unit controls the compression action of the pneumatic air booster pump according to air pressure information detected by the pressure sensor, and when the air pressure detected by the pressure sensor is smaller than preset air pressure, the pneumatic air booster pump is controlled to compress air heated by the air heat collection shed until the air pressure in the air tank main body entering the heat preservation air storage tank reaches the preset air pressure. The control unit controls the heating unit in the heat-preservation air storage tank to heat air in the heat-preservation air storage tank according to the temperature information detected by the first temperature sensor, and when the temperature detected by the first temperature sensor is lower than a preset temperature, the control unit controls the heating unit to heat air in the heat-preservation air storage tank, and at least heats the air in the heat-preservation air storage tank to the preset temperature.
When artificial precipitation is carried out, the electric energy required by the control unit, the first temperature sensor and the pressure sensor is provided by converting the electric energy stored in the storage battery when artificial precipitation is not carried out through the inverter. When artificial precipitation is not carried out, the required electric energy can also be directly provided by the power generation of the turbine generator through the conversion of the inverter because the turbine generator normally works.
Catalyst particles in the smoke furnace body are compressed to preset temperature air of preset air pressure by the pneumatic air booster pump and carried into a target height cloud layer capable of carrying out artificial precipitation, and precipitation is stimulated. In this embodiment, the control unit controls the heating operation of the heating unit and the compressing operation of the pneumatic air booster pump, so as to automatically control the process of the artificial precipitation device.
Embodiment 4 of the present invention is different from embodiment 3 in that the artificial precipitation apparatus further includes: the device comprises an air compression input valve, a pneumatic power generation outlet valve, a preset number of smoke furnace chimney outlet valves, a wind direction information transmitter, a heat preservation gas storage tank output valve and a mixed gas output valve.
The air compression input valve is positioned on the side wall of the chimney of the air heat collection shed and used for adjusting the air flow transmitted to the pneumatic air booster pump by the air heat collection shed; the pneumatic power generation outlet valve is positioned at the top of the chimney of the air heat collection shed and used for adjusting the flow of air discharged upwards by the air heat collection shed; a preset number of smoke furnace chimney outlet valves are correspondingly arranged on the smoke furnace chimney outlet; the wind direction information transmitter is arranged on a wind vane and used for transmitting wind direction information to the control unit; the output valve of the heat preservation gas storage tank is positioned between the heat preservation gas storage tank and the furnace body of the smoke furnace; the mixed gas output valve is positioned between the smoke furnace body and the smoke furnace chimney.
The control unit is also used for controlling the on-off state switching of the air compression input valve, the pneumatic power generation outlet valve, the heat preservation air storage tank output valve and the mixed gas output valve; and the opening and closing state control device is used for controlling the opening and closing state of the chimney outlet valves of the smoke stoves in a preset number according to the wind direction information sent by the wind direction information transmitter.
Specifically, the on-off state referred to herein is an open or closed state of the valve. When the air pressure detected by the pressure sensor in the heat-preservation air storage tank is lower than the preset air pressure, the pneumatic air booster pump is started to compress air, so that the air pressure value entering the heat-preservation air storage tank reaches the preset air pressure. At the moment, the control unit controls the air compression input valve to be in a fully opened state, and the pneumatic power generation outlet valve is in a closed state, so that air heated in the air heat collection shed can enter the pneumatic air booster pump through the air compression input valve and the communication pipeline.
In general, in rainy weather, the solar energy absorbed by the heat absorbing material of the air thermal collector and the electric energy converted therefrom are significantly reduced, and thus the power generation efficiency is low. Therefore, when artificial precipitation is carried out, the pneumatic power generation outlet valve is closed for ensuring continuous input of conventional air pressure air, and at the moment, because air which flows up and down does not exist in the air heat collection shed, the fan blade of the turbine generator cannot drive the turbine generator to generate power, and the electric energy stored in the storage battery when artificial precipitation is not carried out is required to be used for supplying power. The alternating current is converted into alternating current through an inverter to supply power for the air compressor and the heat preservation air storage tank.

For example, if the position wind direction information of the chimney outlet of the smoke furnace is the southeast wind, the control unit controls to open the smoke furnace chimney outlet valve positioned in the northwest direction.
The wind direction information transmitter can also be an electric signal transmitter, different wind direction information detected by the wind vane can enable the electric signal transmitter to generate different electric signals, the generated electric signals are sent to the control unit, and the control unit analyzes the wind direction information corresponding to the electric signals according to the obtained electric signals.
When artificial precipitation is carried out, the control unit controls to open the output valve of the heat-preservation gas storage tank and the output valve of the mixed gas, and when artificial precipitation is not carried out, the control unit controls to close the output valve of the heat-preservation gas storage tank and the output valve of the mixed gas. Meanwhile, when artificial precipitation is not carried out and the air pressure in the heat-preservation air storage tank reaches the preset air pressure, in order to ensure that the electric energy stored in the storage battery is enough to support the electric energy requirement of each component during the artificial precipitation, the control unit is required to control the air compression input valve to be in a closed state, and the pneumatic power generation outlet valve is in a fully opened state, so that the air heated in the air heat collection shed can flow into the outside from the chimney of the air heat collection shed through the pneumatic power generation outlet valve, and the generated air flow drives the fan blades to rotate to enable the turbine generator to generate power.
In this embodiment, through set up the valve between each component at artifical precipitation device, control whole artifical precipitation device air current size through the control unit, make the whole process of artifical precipitation controllable, can control the duration of artifical precipitation simultaneously. The catalyst particles are carried by the air at the preset temperature of the preset air pressure, and the opening or closing state of the corresponding outlet is controlled by the smoke furnace chimney outlet valve arranged at the smoke furnace chimney outlet, so that the influence of wind direction on artificial precipitation can be greatly reduced.
On the basis of the above embodiment, the artificial precipitation device further comprises a personnel operation unit for obtaining a decision instruction of whether the worker carries out artificial precipitation.

The control unit 47 controls the whole artificial precipitation device through the decision instruction received by the personnel operation unit 44. The control unit 47 controls the chimney outlet valve 414 of the smoke furnace to switch the on-off state through the wind direction information sent by the wind direction signal transmitter 46. The control unit 47 is also used for controlling the on-off state of the output valve 411 of the heat preservation gas storage tank and the output valve 413 of the mixed gas.
