Description

Technical Field

[0001] The invention relates to the technical field of artificial weather modification, and in particular to an unmanned ground spreading device in mountainous areas. Background Art

[0002] At present, my country's ground-based tools for artificial weather modification mainly include anti-aircraft guns and rockets. These two types of tools are not restricted by meteorological conditions and can quickly and accurately deliver catalysts to designated locations in the cloud. However, these two types of tools must apply for airspace before each operation, and often miss the opportunity to operate in the absence of airspace. In addition, due to restrictions on transportation conditions, these two types of tools can only operate in places with roads and cannot reach mountainous areas, which are often the source of rivers and lakes and are key areas for artificial weather modification operations.

[0003] Therefore, there is a need for an operating device that can be fixedly installed in mountainous areas, unmanned and remotely controlled, which can use the rising air currents in the mountains to send catalysts into the clouds, thereby achieving the purpose of increasing rain, snow and hail prevention, and the timing of the operation is not affected by airspace and transportation conditions. Summary of the invention

[0005] An unattended ground spreading device in mountainous areas comprises a pressurized spreading unit, a shell and a flame strip combustion unit;

[0006] The booster spreading unit is installed at the top of the shell, and the flame strip combustion unit is arranged inside the shell. The air outlet of the flame strip combustion unit is connected to the bottom of the booster spreading unit to form a channel for smoke exhaust. The flame strip combustion unit ignites the flame strip by remote control. The flame strip contains a catalyst. After the flame strip burns, smoke is generated. The smoke is accelerated by the booster spreading unit using the Venturi effect and rises into the air. The smoke is then sent to the cloud layer along with the rising air flow in the mountainous area to achieve the purpose of increasing rain, snow and hail prevention.

[0007] Furthermore, the booster spreading unit comprises an upper cylinder, an inner upper cone, an inner lower cone, a lower ring, an outer cylinder, an upper ring, a fan fixing frame, an outer protective cover and a fan assembly.

[0008] The upper cylinder and the outer cylinder are fitted inside and outside and are concentrically fixed together by the lower ring, and an annular cavity with a closed lower end and an open upper end is formed between the upper cylinder and the outer cylinder. An inner upper cone and an inner lower cone are fixed on the outer circumferential surface of the upper end of the upper cylinder to form a venturi tube structure. The outer protective cover is fixed to the outer surface of the outer cylinder through the upper ring, and the fan group is fixed inside the outer protective cover through a fan fixing frame. An opening is provided on the outer cylinder at a position corresponding to the fan group. After the fan group is started, negative pressure is generated at the upper end of the upper cylinder. Under the combined effect of negative pressure and the Venturi effect, the smoke flow rate and pressure inside the upper cylinder are rapidly increased to form a high-temperature and high-pressure airflow.

[0009] Furthermore, the outer shell includes an upper shell and a lower shell, the lower shell is an octagonal structure, including eight columns, eight upper beams, eight lower beams, four side panels, two equipment maintenance doors and two flame strip loading doors, the lower ends of the columns are provided with circular holes, which can be fixed to the foundation by anchor bolts; the side panels, equipment maintenance doors, flame strip loading doors and upper and lower beams are connected to the columns by bolts; the upper shell includes eight ribs, the main structure of the ribs is formed by bending an isosceles trapezoidal surface, the bending line is parallel to the top and bottom edges, the eight ribs are spliced ​​in the circumferential direction to form a dome, and a circular hole for installing a booster spreading unit is formed in the center of the top of the dome, the bottom of the ribs has a connecting structure corresponding to the upper beam of the lower shell, and the upper shell and the lower shell are connected together by the ribs and the upper beams.

[0010] Further, the flame bar combustion unit comprises a smoke hood, a square mounting chamber, a flame bar and an electric control module;

[0011] The smoke hood is installed above the square installation room and is connected to the pressurized spreading unit. A flame strip and an electric control module are provided inside the square installation room. The electric control module is used to remotely control whether the flame strip is ignited. When the flame strip is ignited, the smoke generated by it enters the pressurized spreading unit through the smoke hood.

[0012] Further, the square installation room includes a bottom plate, a ventilation door, four columns and two side plates;

[0013] The bottom plate is installed at one end of four columns to obtain a main frame of a square installation room; two side plates are installed on both sides of the main frame respectively, and a ventilation door is installed at the back of the main frame.

[0014] Further, the electric control module includes an electric control room door, a corundum tube, a communication unit, a control unit and an ignition circuit, wherein the flame strip is connected to the loop of the ignition circuit;

[0015] The electric control room door is installed in front of the main frame, and the corundum tube, control unit, communication unit and ignition circuit are installed inside the electric control room frame, wherein the inside of the corundum tube is used to place the flame strip to be burned, the communication unit is used to receive external control signals, the control unit is used to turn on the ignition circuit under the action of the control signal, and the ignition circuit is used to ignite the flame strip when turned on.

[0016] Furthermore, the corundum tube as a carrier for flame strip combustion adopts a cylindrical structure, and a through hole is opened on the rear frame of the control room. Each through hole is used to fix a corundum tube. The pressure cover is fixed to the front end of the rear frame of the control room by screws to prevent the corundum tube from slipping out of the through hole; the corundum tube extends out of the rear frame of the control room and faces the interior of the square installation room.

[0017] Beneficial effects:

[0018] 1. The present invention is fixedly installed in mountainous areas through the shell and the flame strip combustion unit. When it is necessary to increase rainfall, increase snow or prevent hail, the test personnel remotely control the electronic control module to ignite the flame strip in the flame strip combustion unit, wherein the flame strip contains a catalyst. After the flame strip burns, smoke is generated. The smoke rises into the air through the smoke hood and the booster spreading unit. The smoke is then sent to the cloud layer along with the rising air flow in the mountainous area to achieve the purpose of increasing rainfall, increasing snow and preventing hail. The operation timing is not affected by airspace and transportation conditions.

[0019] 2. The booster spreading unit of the present invention includes an upper cylinder, an inner upper cone, a lower ring, an outer cylinder, a partition sheet, an upper ring, a fan fixing frame, an outer protective cover and a fan group. Since the DC fan group installed in the outer protective cover delivers high-speed and high-pressure airflow to the inner cavity of the fan, the airflow diffuses upward along the inner wall ring direction after passing through the Bernoulli amplification area to form a negative pressure at the outlet of the upper cylinder. At the same time, due to the Venturi effect between the outer cylinder and the upper cylinder, the flue gas flow rate and pressure at the lower end of the spreading unit will be rapidly increased to form a high-temperature and high-pressure airflow, which can effectively increase the diffusion height of the catalyst and improve the operation effect. At the same time, since the fan and the high-temperature flue gas are not in direct contact, the fan can be prevented from being corroded by the high-temperature flue gas and condensed water, and has high reliability.

[0020] 3. The smoke extraction hood in the flame strip combustion unit of the present invention is a thin-walled hollow shell structure, the upper end face of which is a flange with a through hole, which is connected to the flange at the lower end of the booster spreading unit by bolts, and the lower end is a square structure with a round hole, which is connected to the side panels and columns by bolts. The upper end space of the smoke extraction hood is small, while the lower end space is large, which has a shrinking effect on the smoke, can increase the rising speed of the smoke generated after the flame strip burns, and helps the catalyst reach the specified cloud height.
