It should be noted that the following embodiments are only used to explain the present application and do not constitute a limitation to the present application.

[0030] Embodiment 1:

[0031] As Figures 1 - 4 shown, a lightning protection and grounding device for a radio monitoring special vehicle includes: a cabinet 1, an external vehicle interface box 2, and an external vehicle grounding system 3. The cabinet 1 is used to collect the system devices in the cabinet 1 to the grounding copper bar 4 on the back of the cabinet 1 respectively; several grounding copper posts are provided in the external vehicle interface box 2; among them, one grounding copper post is connected to the grounding copper bar 4; the remaining grounding copper posts are connected to the vehicle body ground; and are used to connect several grounding copper posts to the ground.

[0032] This application improves the lightning protection measures design in areas with frequent thunderstorms. The structure is designed to install 3 grounding copper posts in the external interface box 2 of the vehicle, which are respectively used for vehicle body grounding and lightning protection grounding (grounding copper busbar 4). The system is configured with three grounding piles 9, three grounding wires and a set of grounding grids. First, select a well-grounded earth to lay the grounding grid and drive the grounding piles 9, and then connect to the grounding piles 9 at three points through the grounding wires from the grounding point of the external interface box 2 of the vehicle. This not only solves the problem of large grounding resistance, but also solves the problem of vehicle body grounding, and ultimately prevents personnel and equipment in areas with frequent thunderstorms from suffering electrical injuries.

[0033] One grounding copper busbar 4 is installed in the bending groove of the rear column of each equipment cabinet 1. The grounding copper busbar 4 has a thickness of 5 mm and a width of 30 mm, and the grounding copper busbar 4 is provided with a plurality of screw mounting holes of M4. All the grounding wires of the system equipment are respectively collected on the grounding copper busbar 4 on the back of the cabinet 1 according to their respective grounding types, and the grounding copper busbar 4 is connected to the vehicle body grounding copper post on the external interface box 2 through a 4 mm2 yellow-green double-color grounding wire.

[0034] A power lightning protection module is installed in the distribution box 5. Under normal working conditions, the lightning protection module is in a high-resistance blocking state and does not affect the normal operation of the circuit. When lightning invades or a surge appears in the power supply line, the lightning protection module will conduct immediately with a response speed of nanoseconds, and discharge the lightning or surge current into the earth through a good grounding system to protect the normal operation of the equipment. After the lightning or surge current is released, the lightning protection module quickly returns to the high-resistance state. In some embodiments,

[0035] Three grounding copper posts are installed in the external interface box 2, which are respectively used for vehicle body grounding and lightning protection grounding. An equipotential connection protection mode is adopted among the three grounding copper posts, and an equipotential protector is used to connect the three grounding copper posts. The connection between the grounding copper post and the grounding wire adopts a butterfly nut crimping method. The equipotential protector is installed inside the external interface box 2.

[0036] In some embodiments, the external grounding system 3 is a grounding grid.

[0037] In some embodiments, the grounding grid includes grounding purple copper plates 6 arranged in a triangle, and the three grounding purple copper plates 6 are arranged at the vertices of the triangle; a first tinned copper wave-proof sleeve 7 is provided between any two of the grounding purple copper plates 6, and a second tinned copper wave-proof sleeve 8 is provided between any two first tinned copper wave-proof sleeves 7; a grounding pile 9 is provided on the grounding purple copper plate 6. The second tinned copper wave-proof sleeve 8 is arranged at the midpoint of the first tinned copper wave-proof sleeve 7. The three grounding copper posts are respectively connected to the three grounding piles 9 through grounding wires.

[0038] First, select a well-grounded earth to lay a ground grid and drive in a grounding stake 9, and then connect to the grounding stake 9 through three points of the grounding wire from the grounding point of the external interface box 2 of the vehicle. The grounding stake 9 (copper-clad steel) has a diameter of not less than 30 mm and a stake length of 500 mm; the grounding wire uses a 16-square-millimeter, 6-meter-long rubber yellow-green grounding wire; the ground grid uses a tinned copper wave-proof sleeve, 10 mm wide, and the wave-proof sleeves are connected into a mesh with a grounding purple copper plate 6.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
