The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.
The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.
A multipoint-arranged lightning protection device is shown in figures 1 to 2 and comprises a base 1, a grounding rod 2 is arranged at the bottom of the base, the base is provided with a plurality of extension arms 3, each extension arm is hinged with a grounding piece 4, and the lower end of each grounding piece is provided with a grounding plate 5; the grounding piece and the grounding plate on each extension arm form a grounding point, so that the lightning energy release effect is improved, and the stability of the overall structure of the lightning protection device is improved; typically, the spreader arm is hinged to the base;
the lower end of the grounding rod is provided with a radiation ring 6, and the grounding rod is positioned at a conical tip part 7 at the lower side of the radiation ring; when laying lightning protection ground connection subassembly major structure, the point portion can insert the soil horizon smoothly in, and the earth bar plays the effect of supporting fixed base, and the device that needs lightning protection (such as facilities such as fan tower) is installed in the base top to but form the connection of non-insulating nature (conductivity) with the base. Generally, the base bottom is provided with 1-3 ground rods, when one ground rod is provided, the ground rod is preferably arranged in the middle of the base, when two ground rods are provided, the two ground rods are symmetrically arranged, and when three ground rods are provided, the three ground rods are uniformly distributed at the base bottom to form stable and reliable support.
The base is provided with a lead 8 connected with each grounding plate, and each lead is attached to the corresponding extension arm and the grounding piece on the extension arm;
the grounding rod and the base are rigidly fixed, and can be welded or connected through other connecting pieces. The base is generally in a flat structure, which can keep a large contact area with the soil layer, and the ground rod inserted into the soil (or buried in the soil) can not only play a role of introducing the thunder and lightning into the ground, but also can reliably guarantee the stability of the base.
It should be noted that, the process of whether soil is inserted into soil or buried in soil is only distinguished when the lightning protection grounding assembly is deployed, and the working conditions of the lightning protection grounding assembly are not actually different.
Generally, for softer soils, the present grounding assembly may be pressed (ground rod driven) directly into the ground layer when deployed. Whether the base is submerged below the ground surface or not can be selected according to the requirements of working conditions, and the feasibility of the scheme does not depend on whether the base is exposed on the ground or not, so that no mandatory requirement is imposed on the scheme.
In a gravel environment with a lot of stones or in a case where obstacles are not convenient to install and arrange, each main component of the grounding assembly is generally buried in the earth layer in a form of digging a pit.
The lower end of the grounding piece is hinged to the middle of the grounding plate, the hinged point is located on the upper surface of the grounding plate, and when the grounding plate is arranged, the grounding plate and the grounding piece are allowed to rotate to a certain extent, so that the arrangement of the grounding plate is facilitated. Even under the influence of environment, such as extrusion collision or wind power invasion, a certain deflection is allowed to be generated between the grounding plate and the grounding piece on one side, the grounding plate and the grounding piece always play a role in pulling the main body structure of the base, the stability of the base is ensured, and meanwhile, the permanent damage of the component can be reduced due to adaptive deformation.
The grounding plate is in an arc structure, the concave surface of the grounding plate is arranged on the upper part, and a plurality of grounding rods 9 are arranged on the lower surface of the grounding plate. The grounding rods on the grounding plate are downward and outward radial, so that lightning and discharge guiding effects are realized to the greatest extent, the radiation range is wider, and the using effect is better.
Usually, several radiation rings, generally 2-5, are spaced at the lower end of the ground rod.
Above-mentioned radiation ring is the integrated into one piece structure with the earth bar, and structural stability is good, the condition that the radiation ring drops can not appear, and the radiation ring has realized releasing the effect of electric energy to the wider range of outside, and simultaneously, the external diameter of radiation ring is greater than the diameter of earth bar, has still played the effect of stabilizing the base, promptly, has improved the ground power of grabbing of earth bar, and equipment stability above the base is better.
The grounding piece is made of a non-rigid conductive material (for example, flexible conductive rubber, flexible conductive fibers and the like can be adopted, and of course, steel wires, iron wires or other rod pieces capable of deforming to a certain extent are feasible, and the grounding piece is not required to be bent at will, so long as deformation adjustment of adaptability is realized, and arrangement and embedding are convenient).
The periphery of the base is uniformly provided with 3-6 extending arms, as shown in fig. 3, in an alternative embodiment, the extending arms are telescopically inserted into the base, and can be telescopically adjusted (i.e. pushed into the inner side of the chute of the base or pulled outwards) according to the actual arrangement requirement (such as avoiding hard objects or barriers like stones).
Specifically, the one end that the extension arm stretched into in the base spout can set up slider 10, and the spout end is equipped with baffle 11, deviates from through baffle restriction slider, and then avoids the extension arm to break away from the base, and simultaneously, the slider has still effectually played the electrically conductive effect.
It should be noted that, a lead is arranged between each grounding plate and the base, so as to play a role of 'double insurance', ensure that the lightning led to the base can be effectively conducted to the grounding plate, and have high reliability.
The invention has reasonable structure design, effectively plays a role of discharging through the arranged grounding rod, the grounding piece and the grounding plate, simultaneously, the grounding rod is used as a main supporting structure, and the grounding piece and the grounding plate are used as auxiliary structures, thereby ensuring that the base has excellent stability and is not easy to damage under severe conditions.
In addition, the grounding assembly is convenient to bury and arrange, a pit can be dug according to actual geological conditions, limitation of installation conditions is small, a multipoint grounding structural form is formed, multipoint grounding plays a shunting role, and induced overvoltage of surrounding equipment is greatly reduced. When the foundation pit is arranged, the accurate corresponding position is not needed, the operation difficulty is reduced, and the construction efficiency is improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
