Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0032] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0033] First see Figure 1 and Figure 2 , Figure 1 It is a structural schematic diagram of an embodiment of a lightning induction device based on a flat-plate capacitor of the utility model; Figure 2 The figure is a schematic diagram of the decomposition of the lightning induction device based on the flat capacitor of the utility model. Figure 1 and Figure 2 As shown, the lightning induction device includes a lightning induction component 1, a flat plate capacitor and a grounding component.
[0034] The flat plate capacitor includes a rigid metal plate 2 and a flexible metal plate 3 spaced apart in the vertical direction. In the assembled state, the lightning inducing assembly 1 is connected to the rigid metal plate 2, and the flexible metal plate 3 is connected to the grounding assembly. Specifically, the lightning inducing assembly 1 can be a lightning inducing rocket or a lightning rod. Those skilled in the art can determine the lightning inducing rocket or lightning rod based on common knowledge or prior art. In this way, the lightning inducing assembly 1 and the rigid metal plate 2 can form a lightning inducing channel.
[0035] See next Figures 3 to 5 , Figure 3 It is a structural schematic diagram of a rigid metal plate of the utility model; Figure 4 It is a top view of the rigid metal plate of the utility model; Figure 5 for Figure 4 The cross-section along the AA direction. Figures 3 to 5 As shown, in order to avoid accidental breakdown between the edge of the rigid metal plate 2 and the flexible metal plate 3 during the lightning induction process, the electric field distribution can be changed by changing the structure of the rigid metal plate 2. Specifically, the periphery of the rigid metal plate 2 can be tilted upward to form a tilted portion 21. It should be noted that the curvature of the tilted portion 21 can be adjusted according to the compressive strength. The higher the compressive strength, the larger the curvature of the tilted portion 21.
[0036] Re-read Figure 1 and Figure 2 In order to provide an insulating interval between the rigid metal plate 2 and the flexible metal plate 3, four insulators 5 may be provided between the rigid metal plate 2 and the flexible metal plate 3. The top of each insulator 5 is engaged with the rigid metal plate 2. Specifically, four blind holes 22 may be provided on the rigid metal plate 2. In a connected state, the internal threads of the blind holes 22 cooperate with the external threads on the top of the insulator 5, thereby achieving the connection between the rigid metal plate 2 and the insulator 5.
[0037] Furthermore, since the strength of the flexible metal plate 3 is relatively low, an insulating support frame 4 for placing the flexible metal plate 3 may be provided at the bottom of the flexible metal plate 3. Through holes 41 may be provided at the four corners of the insulating support frame 4.
[0038] The bottom of each insulator 5 may be connected to a connecting column 51, each connecting column 51 passes through a corresponding through hole 41 and is grounded, and the connecting column 51 may serve as a grounding component. A nut may also be assembled on each connecting column 51, and in the assembled state, the nut engages with the bottom of the insulating support frame 4, thereby playing a role in fixing the insulating support frame 4.
[0039] Further, on the left ( Figure 2 The two connecting posts 51 on the right side and the two connecting posts 51 on the left side can be connected by copper wire 6. For example, both ends of the copper wire 6 can be wound around the connecting posts 51. Figure 1 As shown, in the assembled state, the copper wire 6 is pressed onto the flexible metal plate 3, so that the flexible metal plate 3 and the connecting column 51 as the grounding component can be engaged, and the flexible metal plate 3 can be well contacted with the grounding potential. In addition, when the flexible metal plate 3 bulges, it can also slide relative to the copper wire, thereby not affecting the deformation process of the flexible metal plate 3. Furthermore, the four corners of the flexible metal plate 3 can be chamfered, thereby facilitating the placement of the flexible metal plate 3 and avoiding collision between the flexible metal plate 3 and the connecting column 51.
[0040] See also Figure 6 , Figure 6 FIG. 1 is a schematic structural diagram of another embodiment of the lightning induction device based on a flat plate capacitor of the utility model. Figure 6 As shown, after the lightning is attracted, the negative charge is gathered on the lower surface of the rigid metal plate 2 through the lightning attracting channel, and under the action of the electric field, the positive charge is gathered on the upper surface of the flexible metal plate 3 through the connecting column 51 as the grounding component and the copper wire 6. Since the flexible metal plate 3 has a low strength, under the attraction of the positive charge of the rigid metal plate 2, the two ends of the flexible metal plate 3 slide relative to the copper wire 6, and bulge toward the rigid metal plate 2. After the rigid metal plate 2 contacts the flexible metal plate 3, a short circuit occurs, cutting off the lightning attracting channel and forcing the lightning to hang in the air.
[0041] The insulator 5 and the insulating support frame 4 may be made of insulating materials, such as ceramics, polytetrafluoroethylene, etc. The insulating support frame 4 may also be made by cement casting, which may be determined by those skilled in the art according to actual conditions.
[0042] The rigid metal plate 2 is a rigid aluminum plate, and the flexible metal plate 3 is a flexible aluminum film.
[0043] In the book "Lightning Physics", in Chapter 4, "Using Artificial Lightning Technology to Create Ball Lightning", it is mentioned that "when artificial lightning strikes a galvanized steel plate, a fireball is generated. The lower surface of the steel plate is 7.6 cm away from the tip of another galvanized steel rod. The other end of this drainage rod is connected to a piece of fresh pine wood, and the other end of the pine wood is connected to the grounding electrode of a concentrated salt water pool. The diameter of the salt water pool is 2 m. The fireball appears on the upper part of the steel plate and lasts for 648 ms. The fireball detaches from the steel plate and floats in the air for 26 seconds. 6ms. The lightning struck the upper edge of the steel plate, then passed through the center of the lower surface of the steel plate and was caught by the drainage rod below. A spot with a diameter of 9mm was left in the center of the steel plate. The continuous current of this artificial lightning lasted for 300ms and released a charge of 7 coulombs. The maximum distance of the fireball from the surface of the steel plate was 48cm. 4ms after the fireball appeared on the upper steel plate surface, a fireball also appeared on the top of the pine tree pole and lasted for 342ms before gradually detaching from the tree pole and increasing in diameter to 48cm, lasting for 484ms. ". In the ball flash eyewitness report, the straight-line lightning in the air began to gradually bend, and as it further shrank, the bends formed small balls and gradually increased in size, and the sizes varied. Then it turned to shrink, one by one, until it disappeared, and finally only the largest one was left, and the ball flash was formed naturally. However, most of the charge was directly introduced into the ground, making the lightning in the air very small.
[0044] If the lightning attracting device of the utility model is adopted, the lightning attracting component causes negative charges to gather on the lower surface of the rigid metal plate and positive charges to gather on the upper surface of the flexible metal plate through the lightning attracting channel. If the above-mentioned flexible metal plate has low strength, when a flexible aluminum film with low strength is used, under the effect of opposite charges attracting each other, the flexible aluminum film bulges upward and instantly engages with the rigid metal plate, causing the flat plate capacitor to short-circuit and cut off the lightning attracting channel. The flat plate capacitor acts as a switch to turn the lightning attracting channel off. In this way, the lightning is left in the air and gradually bends to form a ball flash. In this way, it can provide assistance for the research and practice of ball flash. In this process, the device can be set in a pit in an area with frequent lightning to avoid safety accidents.
[0045] In other words, the one-time application of flexible metal plates to successively complete the setting of attracting lightning and cutting off its lightning attracting channel is an important technical measure to achieve the goal of keeping lightning in the air.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
