Abstract
The utility model discloses a grounding module. The grounding module belongs to the field of lightning-protection grounding and is used for solving the problems in the manual grounding process that a nonmetal grounding body is damaged in the carrying process and the normal work is influenced, because an electrode core is outwards exposed for a certain length; and the installation is inconvenient. The grounding module comprises a grounding body and an electrode core. The electrode core comprises a main core, inner metal threaded heads and an outer metal threaded head. Two ends of the main core are respectively connected with one inner metal threaded head. The grounding body wraps the main core and the inner metal threaded heads. The outer end of the inner metal threaded head is connected with the outer metal threaded head matched with the inner metal threaded head. The outer end of the outer metal threaded head is connected with flat steel through a screw. The grounding module realizes that in the manual grounding process, the nonmetal grounding body is not liable to be damaged in the carrying process of the grounding module electrode core, a grounding lead can be grounded reliably, and the normal work of a lightning-protection grounding device is ensured.
Description
Technical field
The utility model belongs to lightning protection field, specifically, is a kind of earthing module.
Background technology
Earthing module refer to be embedded in underground grounding electrode with by this grounding electrode to the general name that is connected wire equipment; earthing module has been used in work, lightning protection, protection, instrument control widely; be accompanied by the quickening of people's rhythm of life; industrial expansion, earthing module is also more and more subject to people's attention.In lightning protection; ground connection need to be set; the ground connection of for example lightning rod (line), lightning arrester; object is to make lightning current import smoothly the earth; be beneficial to reduce lightning overvoltage; prevent charged, elimination electric charge; lightning protection has artificial earthing and natural grounding; and in artificial earthing; the electrode cores of tradition earthing module is all to expose earth electrode, and such nonmetal grounding modules, in the process of carrying (installation), easily damages nonmetal module earth electrode; cause earthing module to be scrapped or the reduction of ground connection usefulness, finally cause lightning protection device normally to work.
Summary of the invention
In handling process, hold flimsy defect for the above-mentioned nonmetal grounding modules existing in prior art, the utility model provides one not fragile, the earthing module of long service life.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of earthing module, comprise earth electrode and electrode cores, described electrode cores comprises the outer silk of main core, metal internal thread head and metal head, the two ends of main core are connected with respectively metal internal thread head, earth electrode wraps up main core and metal internal thread head completely, metal internal thread head outer end connects the outer silk of the metal head mating with metal internal thread head, and the outer silk of a metal outer end connects band steel by screw rod.
Adopt the utility model of technique scheme, by main in-core is put, can not be less than at the earth electrode that meets national electrical standard under the regulation of two, reasonably avoid non-metallic body easily to damage in the process of carrying, ground lead is ground connection reliably, has guaranteed the normal work of lightning protection device.
Furthermore, described main core is column type or template, meets the diversity of people's demand.
Furthermore, described earth electrode is template or column type or blossom type along electrode cores direction.The applicable contact area of template is large, the needs of depth as shallow; Column type is applicable to the needs that contact area is little, the degree of depth is dark, and blossom type is applicable to the needs that contact area is moderate, the degree of depth is moderate.
Furthermore, described earth electrode is non-metal module earth electrode, nonmetal module earth electrode be a kind of earth resistance little, bear that high current impulse withstanding capability is strong, long service life.
The utility model compared to existing technology, by the ingenious setting to earthing device, has guaranteed the normal work of lightning protection device, protection equipment and personal safety in the situation that meeting national electrical standard.

Embodiment
In order to make those skilled in the art understand better the utility model, below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated.
As shown in Figure 1, a kind of earthing module, comprise earth electrode 1 and electrode cores, described electrode cores comprises main core 2, outer 4, metal internal thread head 3 and metal, earth electrode 1 selects earth resistance little, bear high current impulse withstanding capability strong, the nonmetal conductive mineral of long service life, electrolyte earth electrode, main core 2 is column types, in order to meet the regulation of minimum two the earth electrode ground connection of earthing device in national electrical standard, the two ends of main core 2 are connected with respectively metal internal thread head 3, in order to prevent that main core 2 is corroded, earth electrode 1 wraps up main core 2 and metal internal thread head 3, metal internal thread head 3 outer ends connect outer 4, the metal mating with metal internal thread head 3, make nonmetal grounding modules in the process of carrying avoided clashing into the fracture damage causing, can be very firm guarantee that module is not easy to fracture, the outer silk of metal 4 outer end connect band steel 6 by screw rod 5, band steel 6 wherein one end is connected on ground lead.
For having met people to difform needs, main core 2 can be also template.According to the needs of contact area, earth electrode 1 can also be selected different shapes, reaches different effects, for example, as shown in Figure 2 and Figure 3, select template to be applicable to contact area large, the needs of ground connection depth as shallow, as shown in Figure 4, Figure 5, select round applicable contact area little, the needs that the ground connection degree of depth is dark, as shown in Figure 6, Figure 7, select blossom type to be applicable to contact area moderate, the needs that the ground connection degree of depth is moderate.
A kind of earthing device module above the utility model being provided is described in detail.The explanation of specific embodiment is just for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection range of the utility model claim.
