Description

Technical Field

[0001] This utility model relates to the field of lightning rod technology, and in particular to a lightning protection structure suitable for prefabricated cabins. Background Technology

[0002] Currently, the protection range of lightning rods in substation designs is circular. If only one lightning rod is installed in a substation, there will be areas that cannot be protected by direct lightning strikes. If two lightning rods are installed, there will be redundancy in the protection range, resulting in wasted costs. If the substation is large in scale, there will be areas outside the overlapping circular protection ranges of the lightning rods that cannot be protected. If the substation is built in a remote mountainous area, the cost of transporting and hoisting large equipment such as lightning rods and the cost of manufacturing lightning rod foundations will increase many times over. Therefore, a lightning protection structure suitable for prefabricated modules is proposed to solve the above problems. Utility Model Content

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1, referring to Figures 1-3 This is the first embodiment of the present invention, which provides a lightning protection structure suitable for prefabricated cabins. It includes:

[0028] Lightning protection assembly 1 includes a fixing frame 11, a connecting seat 12 disposed on the upper end of the fixing frame 11, and a fixing ring 13 disposed on the connecting seat 12 and the surface of the fixing frame 11; and,

[0029] The connecting steel wire 5 is positioned between the connecting seat 12 and the retaining ring 13; and,

[0030] The roof panel 2 is installed at the bottom of the fixing frame 11, and the grounding electrode 4 is installed at the bottom of the roof panel 2; wherein,

[0031] When the roof panel 2 is struck by lightning, the current propagates through the connecting steel wire 5 between multiple fixed rings 13 and is conducted to the ground through the grounding electrode 4.

[0032] The surfaces of the fixing bracket 11 and the connecting seat 12 are provided with through grooves 14, and the fixing ring 13 is inserted into the through grooves 14.

[0033] The through groove facilitates the fixing of the fixing ring 13, ensuring that the fixing ring 13 is fixed and stable.

[0034] A nut is attached to the surface of the retaining ring 13, and the nut is located below the retaining bracket 11.

[0035] The nut can stably fix the retaining ring 13, ensuring a tight connection between the retaining ring 13 and the connecting steel wire 5.

[0036] A limit block is fixed at the upper end of the connecting seat 12, and the limit block is symmetrically arranged relative to the fixing ring 13.

[0037] The limit block can restrict the position of the connecting steel wire 5, ensuring that the steel wire rope 5 does not sway.

[0038] The fixing frame 11 is located at the edge of the roof panel 2, and the fixing frames 11 are connected by connecting steel wires 5.

[0039] The connecting steel wires 5 are connected end to end and fixed to the surface of the connecting seat 12 by the fixing ring 13. Through the dense laying of the lightning protection components 1, the current in all parts of the roof panel 2 can be conducted, so that the current can flow into the ground.

[0040] The lower end of the grounding electrode 4 is connected to the grounding rod by bolts.

[0041] The grounding rod is deeply embedded in the soil, which can completely conduct the current into the earth.

[0042] The roof panel 2 is composed of multiple structural segments spliced ​​together.

[0043] Roof panel 2 is the top cover of the prefabricated cabin. After the prefabricated cabin is erected, roof panel 2 is spliced ​​and erected on the top of the prefabricated cabin by multiple sections of panels, so as to quickly erect roof panel 2.

[0044] The surface of roof panel 2 is sloping.

[0045] A sloping roof can reduce the accumulation of rain and snow on the roof and prevent the roof from deforming due to water and snow pressure.

[0046] Usage process: When lightning strikes the surface of the roof panel 2, the roof panel 2 is made of conductive material. The current is transmitted throughout the entire roof panel 2 through the fixing frame 11 and the connecting steel wire 5. The current on the surface of the roof panel 2 is then connected to the grounding body 4 through the adapter frame 3, and thus conducted to the ground.

[0047] Example 2, refer to Figures 1-3 This is the second embodiment of the present invention, which differs from the previous embodiment in that it also includes,

[0048] The surface of the grounding electrode 4 is connected to a support frame, which is made of insulating material.

[0049] Usage: The support bracket can connect the grounding body 4 to the surface of the house to ensure stable current transmission. The support bracket with insulating material can prevent current from being conducted to the surface of the house, ensuring the safety of personnel.

[0050] Example 3, referring to Figures 1-3This is the third embodiment of the present invention, which differs from the previous embodiment in that it also includes,

[0051] A support frame is fixed to the upper end of the roof panel 2, and an installation frame is fixed to the upper end of the support frame.

[0052] Usage: Photovoltaic panels can be installed using the mounting bracket, ensuring the rational use of space.
