[0029] When the first side plate 3, the second side plate 7 and the sealing plate 8 are all laid horizontally on the ground, the contact area between the bottom of the device and the ground can be increased, thereby improving the overall stability of the device. The expansion plate 4 on one side is pushed outward by the lever 25, and the first moving component connected to one of the expansion plates 4 can drive the second moving component and the expansion plate 4 on the other side to move synchronously in opposite directions through the spur gear 13, so that the expansion plates 4 on both sides can be pushed outward synchronously. The expansion plates 4 are also provided with photovoltaic components, which can improve the solar energy conversion efficiency of the device and facilitate the storage of more electrical energy. When the expansion plates 4 are moved outward, At the same time, the spur gear 13 can drive the first bevel gears 14 on both sides to rotate synchronously, and the first bevel gear 14 can drive the lead screw 18 to rotate through the two second bevel gears 17. The radius of the first bevel gear 14 is greater than the radius of the second bevel gear 17. Therefore, the first bevel gear 14 can drive the second bevel gear 17 to rotate faster, so that the lead screw 18 drives the external lead screw slider 19 to move laterally toward the end close to the bracket 6, and finally the connecting plate 21 can lift the atmospheric electric field instrument body 2 to a vertical state and can fix it in a vertical state without tilting, so as to facilitate the normal operation of the atmospheric electric field instrument body 2;

[0030] The bottom plate 1 is hinged with a second side plate 7 on both sides adjacent to the first side plate 3, and the ends of the two second side plates 7 away from the bottom plate 1 are hinged with a sealing plate 8, and the upper surfaces of the first side plate 3, the expansion plate 4, the second side plate 7 and the sealing plate 8 are fixedly installed with photovoltaic components that can convert solar energy into electrical energy, and the photovoltaic components are solar panels 28, and the two sides of the upper surface of the bottom plate 1 are fixedly connected with battery placement boxes, and batteries can be placed in the battery placement boxes, and are electrically connected to the solar panels 28 and the atmospheric electric field instrument body 2 through wires, and the solar panels 28 can convert the collected solar energy into electrical energy and store it in the batteries, so that the atmospheric electric field instrument body 2 is powered by the batteries;

[0031] Sealing strips 22 are fixedly connected to both sides of the upper surface of the first side plate 3, and a magnet 23 is fixedly connected to the side of the sealing strip 22 away from the bottom plate 1. Grooves 24 adapted to the sealing strips 22 are provided on both sides of the second side plate 7, and the sealing strips 22 can be plugged into the grooves 24. When the device needs to be folded up as a whole, the expansion plates 4 on both sides are first pushed completely into the first side plate 3, and the connecting plate 21 can be driven by the transmission assembly and the screw transmission mechanism to retract the atmospheric electric field instrument body 2 to a horizontal state, and then the second side plates 7 on both sides are rotated to a vertical state, and then the first side plates 3 on both sides are also rotated to a vertical state. At this time, the sealing strips 22 on both sides of the first side plate 3 will be plugged into the grooves 24 on the side of the second side plate 7, and the magnets 23 are magnetically attracted inside the grooves 24, so that the two first side plates 3 and the second side plates 7 can be connected and fixed to each other as a rectangular frame, and finally the sealing plates 8 on both sides are rotated to the top of the rectangular frame and fixed by bolts, and finally the device is stored as a box body;

The solar panels 28 at various locations convert the collected solar energy into electrical energy and store it in the battery, which provides stable and continuous electrical energy for the atmospheric electric field instrument body 2;

[0035] 2. At the same time, the spur gear 13 drives the first bevel gears 14 on both sides to rotate synchronously. The first bevel gear 14 can drive the lead screw 18 to rotate through the two second bevel gears 17, so that the lead screw 18 drives the external lead screw slider 19 to move laterally toward the end close to the bracket 6, and finally the connecting plate 21 can lift the atmospheric electric field instrument body 2 to a vertical state, so as to facilitate the operation of the atmospheric electric field instrument body 2;

[0036] 3. When the device needs to be folded up as a whole, first push the expansion plates 4 on both sides completely into the first side plate 3, and then drive the connecting plate 21 through the transmission assembly and the screw transmission mechanism to retract the atmospheric electric field instrument body 2 to a horizontal state;

[0037] 4. Then rotate the second side panels 7 on both sides to a vertical state, and then rotate the first side panels 3 on both sides to a vertical state. At this time, the sealing strips 22 on both sides of the first side panels 3 will be inserted into the grooves 24 on the sides of the second side panels 7, and the magnets 23 will be magnetically attracted inside the grooves 24, so that the two first side panels 3 and the second side panels 7 can be connected and fixed to each other into a rectangular frame. Finally, rotate the sealing plates 8 on both sides to the top of the rectangular frame and fix the two by bolts. Finally, the device is stored as a box body.
