Description

Technical Field

[0001] The utility model belongs to the technical field of lightning protection and lightning driving equipment, and in particular relates to a non-lightning-contact lightning dissipation device. Background Art

[0002] The non-lightning-dissipating lightning device is a type of lightning protection and driving device. When a thundercloud appears, it can produce passive corona ions, weakening the thundercloud charge and blocking the lightning strike channel between the lightning element charge and the protected target, thereby effectively protecting the protected target. Specifically, its working principle is that when the thundercloud electric field reaches the air breakdown threshold, a corona ion layer is formed above the lightning dissipating device and its protected object, covering the corona ion layer on the protected target to suppress the initiation of the upward positive leader, thereby reducing the possibility of lightning contact and protecting the target object from being struck to a greater extent. At the same time, the ion layer continues to diffuse upward under the action of the thundercloud electric field, interacting with the thundercloud charge, making the cloud-to-ground electrode equivalent to a leakage capacitor, effectively suppressing the thundercloud from charging to the discharge breakdown level, and achieving a lightning protection effect that is not caused by the induction of lightning into the ground by weakening the thundercloud.

[0003] Existing non-lightning-terminated lightning dissipation devices have the following problems: First, the main lightning dissipation component itself has low structural strength and is prone to structural failure under the influence of wind, vibration, etc.; second, in some scenarios, it is often necessary to quickly deploy the non-lightning-terminated lightning dissipation component to the appropriate location and height, and existing facilities cannot meet such application requirements.

[0026] In this embodiment, the outer housing 2 includes an outer housing body 2-1, which is composed of a hemispherical upper portion and a straight lower portion. The hemispherical and straight lower portions are integrally formed. The inner insulator 12 includes a hemispherical upper portion and a straight lower portion. The hemispherical and straight lower portions are integrally formed. The hemispherical portion of the inner insulator 12 is positioned within the hemispherical upper portion of the outer housing 2 and is fixed thereto.

[0027] In this embodiment, multiple internally threaded connection bases 2-2 are located at the top center and around the periphery of the hemispherical housing body 2-1. The base of the discharge rod 1 is threadedly connected to the connection bases 2-2. The discharge rod 1 comprises a discharge rod body 1-1 having threads at its base.

A discharge gap is formed between the upper portion of the discharge electrode 3 and the straight cylindrical cover of the outer cover 2.

[0029] In this embodiment, a conductive rod 4-2 is provided at the center of the support body 4-1. The upper end of the conductive rod 4-2 contacts the bottom of the discharge electrode 3, and the lower end forms a connection terminal for the ground wire. Specifically, a groove is provided at the top of the threaded hole at the bottom of the discharge electrode 3. When the insulating support body 4 is threadedly connected to the discharge motor 3, the upper end of the conductive rod 4-2 fits into the groove, establishing electrical continuity between the discharge electrode 3 and the conductive rod 4-2.

[0030] See Figure 3 , we can see that:

[0031] The adjustable bracket assembly includes a support base 9, on which a primary arm 8 is hingedly mounted.

A base plate can be installed at the top of the tertiary arm 5, and the bottom of the lightning dissipation assembly is fixed to the base plate with bolts.

[0032] Also mounted on the support frame 9 is an erection adjustment assembly 11 for driving the primary arm 8 to swing. Also mounted on the primary arm 8 is a first telescopic adjustment assembly 10 for driving the secondary arm 7 to telescopically move. Also mounted on the secondary arm 7 is a second telescopic adjustment assembly 6 for driving the tertiary arm 5 to telescopically move.

[0037] Operation method:

[0038] Taking the application of the non-lightning termination and lightning dissipation device installed on a mobile vehicle platform as an example, initially, the arms and lightning dissipation components of each level are in a tilted position. At this time, the discharge rods 1 can be removed from the outer cover 2. After arriving at the application site, the first-level arm 8 is first operated to vertically raise 45 degrees, and each discharge rod 1 is installed on the connecting base 2-2 on the outer cover 2. Then, the vertical adjustment component 11 is further operated to make the first-level arm 8 reach an upright state.

[0039] Then operate the second telescopic adjustment component 6 to raise the third-level arm 5 and the lightning dissipation component on its top to a certain height. Then operate the first telescopic adjustment component 10 to raise the second-level arm 7 to a certain height. Finally, the lightning dissipation component is set to a suitable height position, and then the grounding wire is grounded.
