Description

Technical Field

[0001] This utility model relates to the field of target vaporization technology, specifically a target vaporization platform. Background Technology

[0002] Weather modification technologies (such as artificial rainmaking and hail suppression) are important means of coping with meteorological disasters and alleviating water shortages. Among these, silver iodide, due to its excellent ice-nucleating properties, is widely used in cold cloud catalysis operations. Currently, mainstream technologies release silver iodide particles primarily through the following two methods.

[0003] Silver iodide powder is mixed with gunpowder and pressed into cylindrical smoke sticks, which are then transported to the operational area by aircraft and ignited. The high temperature generated by the combustion of the gunpowder causes the silver iodide to sublimate and vaporize, forming aerosol particles that diffuse into the clouds with the airflow. However, this method has significant drawbacks: reliance on explosives: smoke sticks are classified as civilian explosives, and their production, storage, and transportation require approval, a complex and time-consuming process. Low proportion of effective ingredients: a single smoke stick contains only about ten grams of silver iodide, with the remaining components being gunpowder and binders, limiting catalytic efficiency.

[0004] Anti-aircraft artillery rockets use silver iodide-filled projectiles to disperse the catalyst through explosion. While this method can quickly cover a large area, it suffers from problems such as strict ammunition control, high operating costs (over 10,000 yuan per launch), and safety risks. Therefore, this application provides a target vaporization platform to address the problems mentioned in the background art. Utility Model Content

[0020] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0021] refer to Figure 1 This is a schematic diagram of the structure of the base 1. An adjustment mechanism is provided at the upper end of the base 1. The adjustment mechanism includes a support frame 12 fixed to the base 1 by bolts. A lifting rod 13 is rotatably connected to the bottom of the support frame 12. Figure 4 As shown), the lifting rod 13 is a threaded screw. The upper end of the lifting rod 13 passes through and is rotatably connected to the upper end of the support frame 12. A crank handle is fixedly installed on the upper end of the lifting rod 13. Figure 4 , Figure 5 As shown, a lifting platform 14 is installed inside the support frame 12. The lifting platform 14 is T-shaped, and the right end of the lifting platform 14 is penetrated by a lifting rod 13, which is threadedly connected to the lifting rod 13. Guide grooves 15 are provided at both the front and rear ends of the support frame 12, and scale lines 16 are provided on the right side of the guide grooves 15. The left end of the lifting platform 14 extends out of the support frame 12 from the guide grooves 15, and slides up and down inside the guide grooves 15. A set of load-bearing frames 17 is fixedly installed on the left end of the lifting platform 14 by bolts. A load-bearing platform 18 is fixedly installed on the upper end of the load-bearing frame 17, and a fixing rod 19 is fixedly installed on the right end of the load-bearing platform 18. The fixing rod 19 is "7" shaped. A cable management box 2 is fixedly installed between the load-bearing platform 18 and the fixing rod 19 by bolts. The front end of the cable management box 2 is connected to the controller through a cable. The rear end of the cable management box 2 is fixedly installed with an equipment box 3. The equipment box 3 has heat dissipation holes on the left and right sides. The lower end of the equipment box 3 is fixedly installed with a laser device 31. The laser device 31 contains a vibrating mirror and a field mirror.

[0022] In a specific embodiment: the base 1 is connected to the aircraft. By turning the crank, the lifting rod 13 rotates inside the support frame 12. When the lifting rod 13 rotates clockwise, it drives the lifting platform 14 upward through the thread. When the lifting platform 14 moves upward, the load-bearing frame 17 drives the load-bearing platform 18 and the fixed rod 19 upward. At the same time, a cable management box 2 is installed between the load-bearing platform 18 and the fixed rod 19. The rear end of the cable management box 2 is connected to the laser device 31 through the equipment box 3, thereby adjusting the height of the cable management box 2, the equipment box 3 and the laser device 31. The design of the scale line 16 makes the adjustment distance clearer and more intuitive when adjusting the position.

[0023] like Figure 2 , Figure 3 As shown, a U-shaped plate 4 is bolted to the upper rear end of the cable management box 2. A suspension 41 is bolted to the lower rear end of the U-shaped plate 4. The suspension is U-shaped, and a lifting device is provided at the bottom end of the suspension 41. The lifting device includes a lifting base 42 movably mounted on the bottom end of the suspension 41. The lifting base 42 has an internal thread at its center line and is stepped. A lifting platform 43 is fixedly mounted below the rear end of the lifting base 42, increasing the contact area between the lifting platform 43 and the lifting base 42 and increasing the load-bearing capacity. A mounting plate 44 is fixedly mounted on the upper end of the suspension 41. A stepper motor 45 is fixedly mounted on the upper end of the mounting plate 44. A lead screw 46 is fixedly connected to the output end of the stepper motor 45. The lead screw 46 passes downward through the lifting base 42 and is threadedly connected to the internal thread of the lifting base 42 through an external thread. A guide rod 47 is fixedly installed at the front end of the mounting plate 44. A groove is formed inside the guide rod 47, and a slider is slidably connected inside the groove. The lifting base 42 is slidably connected to the rear end of the guide rod 47 via the slider, preventing the lifting base 42 from rotating when the lead screw 46 rotates and thus raises. A camera 48 is fixedly installed on the upper left side of the suspension 41, and a position sensor 49 is fixedly installed on the right side of the suspension 41.

[0024] like Figure 1 , Figure 2As shown, a fixing device is installed above the lifting platform 43. The fixing device includes a first fixing member 5, which is bolted to the lifting platform 43 via a base at its lower end. The outer wall of the first fixing member 5 has external threads, and a first tightening ring 51 is rotatably connected to the first fixing member 5 through the external threads. The base plate inside the first fixing member 5 is fixedly installed to the base plate of a second fixing member 52 via bolts. The second fixing member 52 is rotatably connected to a second tightening ring 53 via external threads. The first fixing member 5 and the second fixing member 52 are conical in shape with a larger diameter at the upper end and a smaller diameter at the lower end. The fixing device can fix two silver iodide targets of different sizes. When it is necessary to fix a larger silver iodide target, the bolts inside the first fixing member 5 used to fix the second fixing member 52 can be removed using a wrench, and then the silver iodide target can be placed inside the first fixing member 5. The first fixing member 5 is then tightened by rotating the first tightening ring 51. This fixes the silver iodide target. When a small silver iodide target is needed, the second fixture 52 can be fixed with bolts. The method of use is the same as that of the first fixture 5.

[0025] In a specific embodiment: After the adjustment mechanism is positioned, the silver iodide target is placed and fixed by the fixing device. Once the aircraft reaches the designated altitude, the controller activates the laser device 31 and the stepper motor 45. The laser device 31 uses a vibrating mirror and a field mirror (both existing technologies) to change the angle of the laser beam, thereby gradually vaporizing the uppermost silver iodide target. When the uppermost ring of the silver iodide target vaporizes into silver iodide particles and is dispersed into the low-temperature clouds, the water vapor in the clouds sublimates into ice crystals centered on the silver iodide particles. The ice crystals continuously absorb surrounding water vapor and gradually increase in size. When the weight of these particles exceeds the buoyancy of the air, they fall from the clouds, thus achieving artificial rain. Simultaneously, after each revolution of vaporization of the silver iodide target, the stepper motor 45 drives the lead screw 46 to rotate via the output shaft. As the lead screw 46 rotates, it moves the lifting base 42 upwards via a thread. The lifting base 42, through the lifting platform 43, raises the fixing device by 0.001-0.05 mm, ensuring the optimal distance between the silver iodide target and the laser equipment 31. Furthermore, during the vaporization process, the operator can observe the smoothness of the vaporization through the camera 48. Once the silver iodide target is completely vaporized, the upper end of the lifting platform 43 contacts the position sensor 49 during its upward movement. The position sensor 49 transmits a signal to the actuator, which, through the controller, shuts down the laser equipment 31 and the stepper motor, stopping the equipment from operating.

[0026] Working principle: After the base plate 1 is fixed to the aircraft or drone, the cable management box 2, equipment box 3, and lifting device are adjusted to the appropriate positions using the adjustment mechanism. After placing the silver iodide target inside the first fixture 5 or the second fixture 52, the corresponding tightening ring is rotated to fix the silver iodide target. When the aircraft reaches the designated altitude, the laser device 31 and the stepper motor 45 are started by the controller. The laser device 31 vaporizes the silver iodide target. When the uppermost silver iodide target is vaporized, the stepper motor 45 raises the lifting base 42 and the lifting platform 43 by 0.001-0.05 mm through the lead screw 46. The stepper motor 45 controls the lifting platform 43 to rise once for each revolution of the silver iodide target vaporization, until the lifting platform 43 contacts the position sensor 49 during its upward movement. After the position sensor is triggered, the control device stops working.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
