Embodiment 1

[0023] Embodiment 1, the present invention provides a kind of lightning protection device for oil well platform, see figure 1 and figure 2 , including: electromagnetic receiving net 1, used to cut the magnetic force lines in the atmosphere, and when thunderstorm clouds are generated, under the action of thundercloud electric field, corona electric ions can be released, wherein the electromagnetic receiving net is preferably multiple, along the The stainless steel solid rods are arranged circumferentially. Generally, there are 3 electromagnetic receiving nets, and the angle between adjacent electromagnetic receiving nets is 120°; it can also be 4, and the distance between adjacent electromagnetic receiving nets is 90°. Angle setting;

[0024] The support device 2 is used to support and fix the electromagnetic receiving net, and has the conduction effect of electric charge, that is to say, the support device is made of a conductor, preferably a 304 stainless steel solid rod; ...

Embodiment approach

[0035] As a specific implementation, the mesh surface of the electromagnetic receiving net 1 is a square hole of 10 mm × 10 mm, so that when the electromagnetic receiving net rotates, it can ensure that the wind passes through to prevent the wind resistance from being too large to affect the rotation of the electromagnetic receiving net. At the same time, it can achieve a better effect of cutting the magnetic field.

[0036] In this application, the above-mentioned de-mine device or the de-mine system device can use the existing device, and the de-mine device can also be arranged in multiple groups to achieve better conversion and / or absorption of the charge energy converted by the electromagnetic receiving network.

[0037] As a specific embodiment, the electromagnetic receiving network produces a maximum ionization current of 30mA of corona ions, a maximum protection angle of 84°, and a maximum protection radius of 10H; wherein, H is the height of the lightning protection and l...

Embodiment 2

[0039] Embodiment 2, the principle of embodiment 2 is the same as that of embodiment 1, and the lightning protection effect is the same. The difference is that the rotating power device is directly connected to the electromagnetic receiving network. Specifically, the lightning protection and lightning protection device for the oil well platform includes: The electromagnetic receiving net is used to cut the magnetic field lines in the atmosphere, and at the same time, when the thunderstorm cloud is generated, the corona electric ions can be released under the action of the thundercloud electric field, wherein the electromagnetic receiving net is preferably multiple, along the following stainless steel solid rod Circumferential setting, generally, there are 3 electromagnetic receiving nets, and the angle between adjacent electromagnetic receiving nets is set at 120°; it can also be 4, and the angle between adjacent electromagnetic receiving nets is set at 90°;

Abstract

The invention relates to a lightning protection and elimination device for an oil well platform. The device comprises an electromagnetic receiving net which is used for cutting a magnetic line of force in the atmosphere and can release corona ions under the action of a thunderstorm cloud electric field when thunderstorm cloud is generated, a supporting device which is used for supporting and fixing the electromagnetic receiving net and has a charge conduction effect, a rotating power device which is used for driving the electromagnetic receiving net to rotate along with wind, a thunder eliminating device which is used for effectively converting and/or absorbing the charge energy converted by the electromagnetic receiving net, and a fixing device which is used for fixing the supporting device on an oil well platform. According to the lightning protection and elimination device for an oil well platform provided by the invention, the phenomenon of cloud-to-ground lightning in a protectionarea can be effectively prevented, and meanwhile, the problems of strong electromagnetic pulse radiation, induced voltage, potential counterattack and the like caused by lightning current discharge are also reduced, so that the lightning protection effect is more effectively improved.

Description

technical field [0001] The invention belongs to the technical field of protection against direct lightning, and in particular relates to a lightning protection and lightning protection device for an oil well platform. Background technique [0002] Lightning is a natural phenomenon in nature. When lightning occurs, super-strong current and voltage will easily cause damage to people's lives and property. Especially in the field of oil exploitation, once lightning and other phenomena occur on the oil well platform, it will bring catastrophic damage to the oil field. Therefore, the lightning protection of the oil well platform has always been the object of research. [0003] Existing lightning protection systems are based on the principle of lightning → ground discharge to prevent lightning strikes. Usually, lightning protection modules are installed in the distribution box to form a power supply lightning protection box, or lightning rods are installed on the oil well platform...
