Description

Technical Field

[0001] This utility model belongs to the field of lightning protection technology, specifically relating to a lightning protection device and a vehicle equipped with a lightning protection device. Background Technology

[0002] Lightning is a natural atmospheric phenomenon, and lightning strikes are a common natural disaster. They are mainly divided into direct lightning strikes and interference from lightning electromagnetic pulses (LEMPs) caused by direct lightning strikes. When a direct lightning strike occurs, lightning discharges between the cloud and the ground, striking buildings, other objects, the ground, or lightning protection devices directly, generating thermal effects, shock waves, and electromagnetic forces, which can cause significant damage.

[0003] According to the relevant requirements of modern lightning protection technology and system lightning protection engineering implementation, system lightning protection technology is usually divided into four aspects: Dividing, Bonding, Shielding, and Earthing. Among them, the external lightning protection system, which consists of lightning rods, down conductors, and grounding devices, is the most critical part.

[0004] Currently, modern lightning protection technology and system-based lightning protection engineering primarily focus on buildings, structures, and ships, with less attention paid to parking lots and vehicles. This is because buildings and structures are relatively tall compared to other objects, while ship navigation areas are relatively open, both easily forming sharp points within a certain range, thus triggering lightning strikes. However, in suburban parking lots, campsites, or remote construction sites, vehicles can also easily form sharp points, thus causing lightning disasters.

[0005] Because buildings and structures generally have relatively spacious areas, large-scale, well-structured, and internally and externally separated lightning protection facilities can be easily installed; while for ships, their hulls are metal conductors, which can effectively introduce lightning current into seawater; therefore, lightning protection technology for vehicles cannot directly utilize the lightning protection technology for buildings, structures, and ships, and thus a lightning protection system that can adapt to the vehicle environment is needed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a lightning protection device and a vehicle equipped with the lightning protection device, which can protect vehicles and other vehicles within the direct lightning protection zone from lightning damage when a lightning strike occurs.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0015] Furthermore, the electric lifting mechanism is also equipped with a battery and / or power plug for supplying power to the electric lifting mechanism.

[0016] Furthermore, the down conductor is a multi-strand copper cable insulated with silicone rubber.

[0017] In a second aspect, a vehicle is provided, characterized in that the vehicle is equipped with the lightning protection device described in the first aspect, wherein the battery includes an on-board battery, and the power plug is electrically connected to the on-board battery.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: By setting up a lightning rod, which is connected to the lifting rod through a transition piece and connected to a fast grounding device through a down conductor, the fast grounding device leads the down conductor to the ground or a grounding terminal; this can protect vehicles and other objects in the direct lightning protection zone from lightning damage when a lightning strike occurs.

[0021] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 1 As shown, a lightning protection device includes a lightning rod 1, a lifting rod 2, a transition member 3, a down conductor 4, and a fast grounding device. One end of the transition member 3 is connected to the lightning rod 1, and the other end is connected to the lifting rod 2; one end of the down conductor 4 is connected to the lightning rod 1, and the other end is connected to the fast grounding device, which is used to lead the down conductor 4 to the ground or a grounding terminal.

[0024] In this embodiment, the lightning rod 1 is a 60 cm high early discharge lightning rod, mainly made of stainless steel, with an early discharge time of 60 microseconds and a maximum lightning current carrying capacity of not less than 100 kA. The lightning rod 1 is connected to the lifting rod 2 through the transition piece 3 and connected to the horizontal grounding body 501 through the down conductor 4.

[0025] The rising mast 2 is used to erect lightning rod 1 in designated locations such as suburban parking lots, campsites, and remote construction sites that lack lightning protection measures, and is located in the center of the area to be protected. The rising mast 2 is equipped with guy ropes 6, a manual lifting mechanism, and an electric lifting mechanism. In this embodiment, the rising mast 2 can be controlled to raise and lower the lightning rod 1 through various methods, including manual operation of the manual lifting mechanism and Bluetooth remote control of the electric lifting mechanism via mobile phone software. The electric lifting mechanism is equipped with a wireless receiving module for receiving lifting commands sent by a mobile terminal, and a control module for controlling the raising and lowering of the rising mast 2 according to the lifting commands received by the wireless receiving module. The electric lifting mechanism is also equipped with a battery and / or power plug for powering the electric lifting mechanism. In this embodiment, the maximum lifting height of the rising mast 2 is 13 meters (including the height of the transition piece 3), and the radius of the direct lightning protection zone formed is not less than 64 meters. Internally, it includes a Bluetooth receiver module (wireless receiver module) to receive lifting commands transmitted via Bluetooth from mobile software (mobile terminal, which can also be a computer, vehicle controller, etc. in addition to a mobile phone); a control chip (control module) to control the lifting of the lifting rod 2 according to the lifting commands received by the Bluetooth receiver module, thereby controlling the lifting height of the lightning rod; and a lithium battery to power the lifting rod 2, the Bluetooth receiver module, and the control chip. The lightning rod lifting rod 2 meets the requirements of mechanical strength, corrosion resistance, and thermal stability.

[0026] The transition piece 3 serves two purposes: firstly, to securely fix the lightning rod 1 and the lifting rod 2; and secondly, to isolate the lightning rod 1 and the lifting rod 2, preventing the lightning current from being conducted to the lifting rod 2 and thus causing damage to it.

[0027] In this embodiment, the fast grounding device includes a horizontal grounding electrode 501 and a vertical grounding electrode 502. The horizontal grounding electrode 501 and the vertical grounding electrode 502 are connected by a nut via structural components. The horizontal grounding electrode 501 is a 100 square millimeter copper strip, and the vertical grounding electrode 502 is a copper-plated grounding electrode with a diameter of 25 millimeters and a length of 1 meter, equipped with a hardened tip connector and a drive head for easy insertion into the ground. The lightning rod 1 guides the lightning current to the ground or a grounding terminal via the down conductor 4, the horizontal grounding electrode 501, and the vertical grounding electrode 502.

[0028] The down conductor uses 50 square millimeter multi-strand copper cable, which is wrapped with silicone rubber insulation.

[0029] The lightning rod 1, transition piece 3, lifting rod 2, down conductor 4, and quick grounding device are all connected by nut crimping.

[0030] Before a lightning strike occurs, a lifting pole 2 is erected at the center of the pre-set direct lightning protection zone, and the installation of lightning rod 1, transition piece 3, down conductor 4 and fast grounding device 5 is completed. Finally, the lightning rod 1 is connected to the ground through horizontal grounding body 501 and vertical grounding body 502.

[0031] Before a lightning strike, the lifting pole 2 is raised manually or via Bluetooth connection to a mobile phone. When a lightning strike occurs, the lightning arrester 1 conducts the lightning current to the ground through the down conductor 4 and the fast grounding device, thereby protecting vehicles and other objects within the direct lightning protection zone.

[0032] When encountering strong winds, the lifting pole 2 is secured by adding wind ropes 6 to enhance its wind resistance; after the lightning strike stops, the lifting pole 2 can be lowered manually or via Bluetooth connection to a mobile phone.

[0033] As a preferred embodiment of the above, the grounding resistance of the selected lightning rod should be as small as possible; however, when used in a small grounding grid scenario with good and relatively balanced soil conditions, and provided that the total length of the horizontal and vertical grounding electrodes is not less than 5 meters, the impact of the lightning rod's grounding resistance on direct lightning protection can be ignored.

[0034] As a preferred embodiment of the above, the protection capability of the lightning arrester against direct lightning strikes can be increased by increasing the number of fast grounding devices to two or more.

[0035] As a preferred embodiment of the above, the installation location of the lightning protection device should be more than 3 meters away from the sidewalk, cable trench and equipment entrance / exit, so as to avoid the impact of lightning current conducted to the ground through the lightning protection device on the surrounding facilities.

[0036] The lightning protection device described in this embodiment includes a lightning rod, down conductor, transition piece, lifting rod, and quick grounding device. The components are connected by screw holes, making the installation simple, disassembly and carrying convenient, and facilitating vehicle transport and field installation.

[0037] The lightning protection device described in this embodiment can form a direct lightning strike protection zone with a large radius, providing effective lightning disaster protection for vehicles and other objects within the direct lightning strike protection zone.

[0038] In this embodiment, the lifting mast can be adjusted in height through manual operation and via Bluetooth connection to a mobile phone. In the absence of lightning strikes, the mast can be lowered without disassembly to avoid damage from strong winds. When a lightning strike is imminent, the mast can be raised to prevent lightning strikes. When a lightning strike is imminent and accompanied by strong winds, the lifting mast of the lightning arrester can be secured with guy ropes to enhance wind resistance.

[0040] Based on the lightning protection device described in Embodiment 1, this embodiment provides a vehicle equipped with the lightning protection device described in Embodiment 1. The vehicle equipped with the lightning protection device is powered by an on-board battery, that is, the battery includes an on-board battery or the power plug is electrically connected to the on-board battery.

[0041] In this embodiment, the lifting rod 2 can be installed at a set position on the vehicle (such as the vehicle frame) via a connector, serving as one of the vehicle's functional accessories.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
