Description

Technical Field

[0001] The invention belongs to the technical field of artificial rainfall enhancement equipment, and in particular relates to an airborne rainfall enhancement flame strip and a spreader thereof. Background Art

[0002] Among various catalytic operation methods for artificial weather modification, aircraft directly entering the cloud layer for seeding is the best solution. For large-scale weather processes, aircraft can directly seed catalysts into predetermined locations in the cloud. Aircraft have strong maneuverability and are characterized by uniform seeding, large operating area, and wide impact range. Whether it is artificial rainfall enhancement operations to meet agricultural drought resistance or data detection and targeted scientific research, aircraft have obvious advantages.

[0003] At present, the internal structures of the airborne rainmaking flame strips used for domestic aircraft rainmaking operations are basically the same, and there are only two forms of external structures. The spreaders of the two airborne rainmaking flame strips with different appearance structures are specially designed and applied according to their appearance characteristics. The first type of airborne rainmaking flame strip is fixed in a position by connecting a through hole at the end of the flame strip with a pin to a corresponding through hole on the spreader; the second type of flame strip is fixed in a slot of the spreader by squeezing two terminal poles at one end of the flame strip that are provided with elastic force by a spring and rotating the two pins on the flame strip to limit the flame strip.

[0004] Through market application, it was found that the above two types of airborne rainfall enhancement flame strips and spreaders have certain safety hazards in actual use.

[0005] The first type of airborne rainmaking flame strip is fixed to the spreader by a pin limiter. The other parts of the flame strip have no support, and the center of gravity of the flame strip is suspended. During takeoff, flight and landing, the flame strip is always in a state of vibration, shaking, pulling and twisting the pins with the connection point as the torque point. The flame strip is made of fiberglass and the connection point is drilled with a through hole for connection and limit fixing with the spreader, making it the weakest part of the entire flame strip. There is a possibility that the flame strip will be damaged and torn off with the through hole as the point of fall. It is extremely dangerous to fall off the flame strip during flight! Similar situations have indeed occurred in actual flight application operations.

[0006] The second type of airborne rainmaking flame strip is to squeeze two terminals at one end of the flame strip, which are provided with elastic force by springs, and then rotate and clamp the two pins on the flame strip to limit and fix it in the slot of the spreader. Although most of the flame strip is wrapped and supported, the main force-proof anti-detachment points are concentrated on the springs and the pins. During the takeoff, flight and landing of the aircraft, the flame strip and the spreader are always in force vibration. The long-term extrusion and deformation of the spring will eventually lose its elasticity. The pin is fastened to the flame strip through threads and anti-loosening heat-resistant glue. Under such severe vibration and high-temperature combustion operations inside the flame strip, there will eventually be a moment when it will come off and take effect. Once the pin or spring is ineffective, the flame strip will directly fall off the spreader, which is extremely dangerous! And similar situations have indeed occurred in actual flight application operations.

[0007] In summary, the existing airborne rainfall enhancement flame strips are at risk of falling off during installation or use, which is very unsafe to use and has great safety hazards. At the same time, the connection points of the two existing airborne rainfall enhancement flame strips are relatively hidden, which is not convenient for safety inspection and maintenance. Summary of the invention

[0008] The purpose of the present invention is: In summary, the existing airborne rain-enhancing flame strips are in danger of falling off during installation or use, which is very unsafe to use and has great safety hazards. At the same time, the connection points of the two existing airborne rain-enhancing flame strips are relatively hidden, which is not convenient for safety inspection and maintenance. An airborne rain-enhancing flame strip and its spreader are provided.

[0009] The technical solution adopted by the present invention is as follows:

[0010] An airborne rain-enhancing spreader comprises a guide body, a control device installation cavity and a flame bar fixing body, wherein the guide body comprises a fairing and a support plate, six bolts are pre-fixed on the support plate, and the fairing is welded to the support plate;

[0011] The control device installation cavity includes a machined angle aluminum frame, an aluminum box, positive and negative terminal poles and an aviation socket. The machined angle aluminum frame is partially embedded in the aluminum box, and the connection between the two is welded and riveted. The exposed portion of the angle aluminum frame is processed with six fastening holes that are connected to the six bolts pre-fixed on the support plate. The upper end of the aluminum box is provided with multiple holes for installing the positive and negative terminal poles, and the lower end of the aluminum box is provided with a hole for installing the aviation socket. The positive and negative terminal poles and the aviation socket are directly connected by welding with a control cable;

[0012] The flame strip fixing body comprises a hanging plate, an aluminum groove, a lower clamping block and an upper clamping block. The hanging plate and the aluminum groove are connected by welding or riveting. The lower end of the aluminum groove is fastened to the lower clamping block by two bolts, and the upper end of the aluminum groove is fastened to the upper clamping block by one bolt.

[0013] The guide body and the control device installation cavity are fastened and connected by six bolts, and the control device installation cavity and the flame strip fixing body are connected by welding and riveting to form a spreader.

[0014] Wherein, the internal structure of the flame strip remains unchanged, and the outer shape is formed by winding glass fiber reinforced plastics.

[0015] The connection between the suspension plate and the aluminum trough is achieved by welding and riveting. The exposed connection parts are welded and the other parts are riveted.

[0016] Wherein, a plurality of semicircular grooves are processed in the upper clamping block and the lower clamping block.

[0017] The suspension plate is made of high-strength aviation aluminum plate, and is provided with holes for connecting with the aircraft external rack.

[0018] Among them, the outer surface of the flame strip is provided with circular convex steps that are integrally wound and formed, one in front and one in the back.

[0019] Wherein, the outer diameter of the circular convex step is larger than the inner diameter of the semicircular groove.

[0020] The control device mounting cavity and the flame bar fixing body are welded and riveted in two ways, with the exposed connecting parts welded and the other parts supplemented by riveting.

[0021] The fairing is an elliptical shape formed by welding aluminum plates, and is in the shape of an elongated strip as a whole. The support plate is a rectangular aluminum plate, and six bolts are pre-fixed on the support plate.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

The glass fiber material has the characteristics of light weight, high specific strength, corrosion resistance, good electrical insulation performance, slow heat transfer, good thermal insulation, and good resistance to instantaneous ultra-high temperature.

[0025] 3. In the present invention, the spreader is exposed and open in a line, so that the flame strip burns and dissipates heat very quickly, making maintenance very convenient.

[0026] 4. In the present invention, all load-bearing fasteners of the spreader are exposed to facilitate safety inspection. BRIEF DESCRIPTION OF THE DRAWINGS
