[0002] Conventional weather modification (rain enhancement, rain elimination or hail prevention) mainly refers to changing the microphysical morphology of clouds that meet certain conditions by artificially spreading catalysts, thereby achieving the purpose of increasing or reducing precipitation, and can inhibit or reduce the occurrence of hail.

[0003] The existing means of artificial catalysis mainly include manned aircraft, rockets, anti-aircraft guns, and high-altitude chimneys, etc. Most of them are to spread catalysts into the clouds in the form of combustion or explosion. Some areas have begun to try to use drones to carry catalysts for artificial weather modification operations. When drones and rockets are performing artificial weather modification operations, it is crucial to grasp the location and timing of the cloud seeding, which is also the key to the effectiveness of artificial weather modification operations. Therefore, it is very important to detect when to enter the cloud and to detect the water content and water-rich locations in the cloud for artificial weather modification.

[0004] The applicant has discovered that the existing ground-based artificial weather modification operation technology has at least the following technical problems: due to the lack of means to detect and observe the target cloud clusters (currently, operations can only rely on visual observation or radar), the positioning accuracy of the water-rich cloud clusters is poor, and the timing of the operation cannot be accurately grasped. Summary of the invention

[0036] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0038] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0039] Reference Figures 1 to 7 The present invention provides a cloud entry detection device, comprising a detection board 1 and an electrode grid assembly 2, wherein the electrode grid assembly 2 is connected to the detection board 1, and the electrode grid assembly 2 comprises a positive electrode 21 and a negative electrode 22, wherein the positive electrode 21 comprises at least one conductive grid bar, and when there are multiple conductive grid bars, all the conductive grid bars are arranged in parallel, and the negative electrode 22 comprises at least one conductive grid bar, and when there are multiple conductive grid bars, all the conductive grid bars are arranged in parallel, and the conductive grid bars on the positive electrode 21 and the conductive grid bars on the negative electrode 22 are arranged alternately with intervals, and adjacent conductive grid bars are not connected to each other;

[0040] When a water droplet is adsorbed on the detection board 1, if it just covers two adjacent conductive bars, since the cloud water contains impurities and the impure water has electrical polarity, the electrodes are turned on and current is generated in the circuit. By measuring the resistance in the loop, the resistance value on the detection board 1 can be obtained, and then the water content in the cloud can be known;

[0041] The cloud entry detection device utilizes the conductivity characteristics of cloud water to determine the current position of instruments and operating tools in the cloud by measuring the conductivity of cloud droplets and cloud water adsorbed on the detection plate 1. It can be widely used in the timing selection and grasp of the operating position when drones and rockets spread catalysts in the cloud.

[0042] As an optional embodiment, there are multiple electrode grid assemblies 2, and the multiple electrode grid assemblies 2 are arranged in sequence, and the spacing between two adjacent conductive grid bars in the electrode grid assembly 2 located relatively in the center is greater than the spacing between two adjacent conductive grid bars in the electrode grid assembly 2 located relatively in the outside;

[0043] Since warm cloud catalysis mainly targets cloud droplets and small water droplets, large nuclei are formed by spreading hygroscopic catalysts or by local cooling. Generally, small water droplets exist. Therefore, the electrode grid assembly 2 is placed in multiple levels of density, that is, the intervals at the outside are smaller and the intervals at the middle are larger, so that the water droplets in the cloud can be preliminarily classified;

[0044] In this embodiment, the number of electrode grid assemblies 2 located on the same side is preferably three. The three electrode grid assemblies 2 are divided into three circuits, which are connected and measured separately, and can fully reflect the abundance of water content in the cloud.

[0045] As an optional implementation, both sides of the detection plate 1 are connected with an electrode grid assembly 2. With this arrangement, the water content in the cloud can be measured on both sides of the detection plate 1, and the water vapor in the cloud can be received to the maximum extent and in all directions, which can make the measurement of the water content in the cloud more comprehensive.

[0046] In this embodiment, the number of electrode grid assemblies 2 on both sides may be the same or different, and can be flexibly selected and set according to actual use requirements.

[0047] As an optional embodiment, a heating unit 3 is further included. The heating unit 3 is arranged inside the detection board 1. The heating unit 3 can increase the temperature of the detection board 1. In this embodiment, the heating unit 3 preferably adopts an electric heating method, and its main structure is preferably a resistance wire;

[0048] Since the cloud contains abundant water vapor and the temperature is low, the temperature dew point difference (T-Td) is low. If the temperature of the detection plate 1 is lower than the dew point, the water vapor in the cloud will condense on the detection plate 1, affecting the judgment of the liquid water content in the cloud. Therefore, a heating unit 3 is arranged in the middle interlayer of the detection plate 1. By applying current to cause the resistance wire to heat up, the temperature of the detection plate 1 is increased to be higher than the dew point temperature, but it does not cause the water droplets adsorbed on the detection plate 1 to evaporate quickly.

[0049] In this embodiment, the detection board 1 is preferably equipped with a temperature measuring element, which can measure the real-time temperature of the detection board 1 and automatically adjust the current passing through the resistance wire according to the real-time temperature, thereby adjusting the heating value of the resistance wire. The temperature of the detection board 1 is preferably set to be 5°C higher than the temperature in the cloud, and is adjusted based on this standard, and is always kept above 0°C to prevent frost.

[0050] In addition, in addition to the above-mentioned defrosting function, the heating unit 3 can also remove water stains on the surface of the detection plate 1 through its heating effect, thereby ensuring the test accuracy and providing multiple measurement results, enriching the basic functions.

[0051] As an optional implementation, it also includes a water stain erasing unit 4, which is connected to the detection board 1. The water stain erasing unit 4 can erase the water stains on both sides of the detection board 1, thereby ensuring the test accuracy and providing multiple measurement results;

[0052] The water stain erasing unit 4 preferably includes a servo motor 41, a screw slide 42 and a wiper 43. The servo motor 41 is drivingly connected to the screw slide 42, and the screw slide 42 is transmission-connected to the wiper 43. The wiper 43 is preferably an annular structure sleeved on the outside of the detection plate 1, so that it can play a role in erasing water stains on both sides of the detection plate 1. After the servo motor 41 is started, it can drive the screw slide 42 to start, and the screw slide 42 can drive the wiper 43 to move back and forth relative to the detection plate 1, and the water stains on the detection plate 1 are wiped off by the reciprocating motion of the wiper 43.

[0053] As an optional implementation, it further includes an environmental information measuring unit 5, which is connected to the detection board 1;

[0054] The environmental information measuring unit 5 preferably includes a temperature measuring element, a humidity measuring element, and an air pressure measuring element. By providing the above elements, accurate measurement of physical quantities such as temperature, humidity, and air pressure can be ensured, and correct temperature guidance can be provided for components such as the heating unit 3. By measuring and calculating the above physical quantities, the real-time air pressure height of the detection board 1 can be accurately obtained;

[0055] In this embodiment, different components can be provided separately or integrated. For example, the temperature measuring component and the humidity measuring component can be connected to the detection board 1 separately, or they can be integrated into one temperature and humidity measuring component and then connected to the detection board 1.

[0056] As an optional implementation, it also includes a data interface 6, which is connected to the detection board 1, and the data interface 6 can ensure the applicability of the detection device;

[0057] In this embodiment, the data interface 6 is preferably a universal data interface, and further preferably a USB Type-C interface, which can transmit power of more than 20w, which can meet the power demand of the detection board 1, and can also transmit all the detection data on the detection board 1, including resistance, detection board temperature, air temperature, air pressure, humidity and other measurement data back to the data acquisition and processing device, so as to reduce and reduce the number and weight of components on the detection board 1 as much as possible;

[0058] In addition, the detection board 1 is preferably also provided with a USB Type-C female interface, which can be connected to other devices and can also provide power support and data transmission to other devices.

[0059] As an optional implementation, it also includes an isolation cover unit, which is arranged on the outside of the detection plate 1. The isolation cover unit can isolate raindrops in the cloud, thereby effectively ensuring the measurement effect.

[0060] As an optional embodiment, the isolation cover unit includes a cage cover body 7, the cage cover body 7 includes a baffle 71 and a first connecting plate 72, a plurality of baffles 71 are arranged at intervals along the circumferential direction and respectively form an outer ring layer located on the outside and an inner ring layer located on the inside, the baffles 71 on the outer ring layer and the baffles 71 on the inner ring layer are arranged alternately, and both ends of all the baffles 71 are respectively connected to the two first connecting plates 72, and the two first connecting plates 72 are respectively connected to the two ends of the detection board 1;

[0061] Since the baffles 71 on the outer circle layer and the baffles 71 on the inner circle layer are arranged alternately, the two circles of baffles 71 are staggered at a certain angle, so that raindrops cannot directly hit the detection plate 1, and at the same time, it is also conducive to the airflow in the cloud to carry cloud droplets through. The structure of the cage cover 7 is relatively simple and easy to install. Raindrops or large water droplets in the cloud are not likely to directly interfere with the detection plate 1, and the detection effect is better.

[0062] Furthermore, all the baffles 71 and the two first connecting plates 72 can be combined to form a symmetrical design. Each first connecting plate 72 is initially connected to half the number of baffles 71. During actual installation, the two symmetrical structures can be directly connected, and the assembly can be completed directly by plugging, splicing and gluing, making the structural assembly simpler and faster.

[0063] As an optional embodiment, the isolation cover unit includes a tower cover body 8, the tower cover body 8 includes a mask 81, and a plurality of masks 81 are sequentially connected along the length direction of the detection board 1 and are collectively arranged on the outer side of the detection board 1;

[0064] A plurality of shields 81 form a multi-layer tower shape, and the detection board 1 is covered therein, which is hollow at the top and bottom, so that air and cloud droplets can keep flowing. When the detection board 1 is used, it is placed upright, and horizontal water droplets cannot directly splash onto the detection board 1;

[0065] In this embodiment, the number of the shields 81 is preferably three, and two adjacent shields 81 can be fastened by plugging in knobs, thereby eliminating the need for additional screws or glue, making the structural assembly simpler and faster.

[0066] As an optional embodiment, the isolation cover unit includes a mesh box cover body 9, the mesh box cover body 9 includes a gauze 91 and a second connecting plate 92, the gauze 91 is annular and is covered on the outside of the detection plate 1, and the two ends of the gauze 91 are respectively connected to a second connecting plate 92, and the two second connecting plates 92 are respectively connected to the two ends of the detection plate 1;

[0067] The gauze 91 can be combined with two circular second connecting plates 92 to form a gauze cage, and the detection plate 1 is located in the gauze cage. In this embodiment, the gauze 91 preferably adopts a 30-100 mesh gauze with a pore size of approximately 0.25-0.8mm, which is conducive to the airflow carrying cloud droplets in and out of the gauze cage, while raindrops and large water droplets will be blocked by the gauze.

[0068] The cage-type cover body 7, tower-type cover body 8 and mesh box-type cover body 9 are all selectable structural forms of the isolation cover unit. The specific structural form of the isolation cover unit can be flexibly selected according to actual use requirements.
