Description

TECHNICAL FIELD

[0001] The application relates to a connection method of a photovoltaic lightning protection system and a support, and belongs to the technical field of photovoltaic lightning protection grounding. BACKGROUND

[0002] During photovoltaic installation construction, the photovoltaic support needs to be grounded to achieve lightning protection, so as to avoid damage to the photovoltaic support device caused by lightning strikes (see Chinese Patent Publication No. CN220915196U).

[0003] In the gobi desert environment, the conductivity of the soil at a single construction point of the photovoltaic support is inconsistent. In order to improve the lightning protection conductivity of multiple photovoltaic supports in a photovoltaic power generation field, the steel pipe piles of multiple photovoltaic supports need to be welded with grounding flat steel, and then the grounding flat steel is connected to the grounding block, and the grounding block is uniformly grounded. When the grounding flat steel 11 is welded at the pipe clamp 13 of the steel pipe pile 12, the welding layer 11 causes a spacing space h between the pipe clamps 13, so that the bolt and nut fastening assembly 14 cannot be tightly stressed against the pipe clamps 13, as shown in FIG. 1, thereby affecting the stability of the pipe clamps 13 clamping the steel pipe pile 12 as a force support of the inclined rod 15.

[0021] A grounding flat steel bar 11 is laid within the Gobi soil layer 1. The end of the grounding flat steel bar 11 extending out of the Gobi soil layer 1 is welded and fixed to the steel pipe pile 12 through a welding layer 11. A pipe clamp 13 is installed on the steel pipe pile 12 at the welding layer 11. The pipe clamp 13 is composed of a pipe clamp flap A131 and a pipe flap clamp B132. The pipe clamp flap A131 and the pipe flap clamp B132 are tightened in opposite directions by a bolt and nut fastening assembly 14.

The elastic arch spring 41 has through holes at both feet that pass through the bolt rod in the bolt and nut fastening assembly 14. It also includes an intermediate plate 42 with a guide slide 43. The intermediate plate 42 slides with the bolt rod in the bolt and nut fastening assembly 14 through the guide slide 43. The intermediate plate 42 contacts the inner side of the two feet of the elastic arch spring 41, so that the outer side of the two feet of the elastic arch spring 41 contacts the inner side of the pipe clamp A131 and the pipe clamp B132.

[0023] The elastic arch spring 41 and its inner intermediate plate 42 fill the gap h between the inner sides of the pipe clamp A131 and the pipe clamp B132, so that the bolt and nut fastening assembly 14 can achieve stable tension on the pipe clamp A131 and the pipe clamp B132, ensuring the stability of the pipe clamp 13 clamping the steel pipe pile 12 as the inclined rod 15, and solving the problem that the gap h between the pipe clamps affects the stability of the pipe clamp clamping the steel pipe pile as the inclined rod.

The positioning plates 44 are engaged with the horizontal section of the grounding flat steel 11 to receive force. The positioning plates 44, supporting the intermediate plate 42 on the grounding flat steel 11 via the lifting assembly, only provide auxiliary force and do not affect the connection force between the grounding flat steel 11 and the steel pipe pile 12.
