Abstract
The utility model relates to a multichannel electromagnetic field shielding hardware which not only can be laid vertical to be used as a support tower body but also can be laid horizontally to be used as a span support. The hardware comprises a hardware basal body and is characterized in that the hardware basal body is composed of at least three metal cable pipelines, the metal cable pipelines are provided with pipeline inlets and pipeline outlets, every two adjacent metal cable pipelines are mutually parallel and are fixedly connected through metal connection pieces. The utility model has simple and practical structure, has the function of electromagnetic field shielding, can be fixedly connected in multiple, can be arranged vertically or in parallel, protects cables and effectively prevents the generation and the hurt of the electromagnetic field.
Description
Technical field
The utility model relates to a kind of not only can the setting as supporting tower body but also can keeping flat the multichannel electromagnetism electric field shielding hardware that supports as crossing over.
Background technology
Existing support tower is made of a plurality of hardware assemblings, being widely used in takes shelter from the thunder and communicate by letter waits as the support tower body, allow lightning-arrest downlead or order wire directly pass gap between the hardware that supports tower body, lead to the lower end of supporting tower body from the upper end of supporting tower body.Because existing lightning-arrest downlead or order wire lack electromagnetic-field-shielded layer protection, down conductor system can produce powerful electromagnetic radiation around its downlead itself when drawing down thunder-strike current, and electronic apparatus to external world carries out electromagnetism destruction.On the contrary, order wire will be subjected to the interference of external electromagnetic field when lacking electromagnetic-field-shielded layer protection, make the communication line signal impaired.In addition, sometimes the technical staff passes between the hardware gap around coming around the trouble of going for fear of down conductor system or order wire, also in order to save the wire rod that detours between hardware, it is external then directly down conductor system or order wire to be arranged on support tower, like this, though saved wire rod, the wire rod outside being exposed to is easier just to be damaged.Therefore, the hardware of existing support tower has defective, need improve.
The utility model content
The purpose of this utility model is to improve on the hardware structure of existing support tower, and a kind of multichannel electromagnetism electric field shielding hardware is provided.
Multichannel electromagnetism electric field shielding hardware of the present utility model has the hardware matrix, it is characterized in that described hardware matrix is made of at least three strip metal cable pipelines, described wire rope pipeline has pipeline inlet and pipeline outlet, described adjacent metal cable pipeline is parallel to each other, and is fixedly connected by metal connecting piece between the described adjacent metal cable pipeline.
The matrix of hardware described in the utility model is made of at least three strip metal cable pipelines, be meant that promptly described hardware matrix both can be made of three strip metal cable pipelines, also can constitute, as hardware matrix of constituting by seven strip metal cable pipelines etc. by the wire rope pipeline more than three.Its structure can be a polytype, as is made for triangular form tower structure or polygonal pyramidal structure etc., and like this, both mechanical structure was stable
The existing metal material of the matrix adopting of hardware described in the utility model is made, as steel member matrix, iron member matrix, copper member matrix or aluminium alloy element matrix or the like.The matrix of hardware described in the utility model can a plurality of fixedly connected formation support towers, circuit is crossed over and supported or other load-bearing is crossed over and supported, can connect by existing fixedly connected mode such as welding, riveted joint or flange connection between the adjacent metal member matrix, as long as can pass outside order wire or down conductor system smoothly in the wire rope pipeline.
When using multichannel electromagnetism electric field shielding hardware of the present utility model, can be earlier that a plurality of hardware matrixes are fixedly connected, after fixedly connected, vertical installation can be worked as the lightning-arrest support tower that supports tower body and other communication etc. and be used, parallel installation can be used for circuit and crosses over support and other load-bearing leap support, then, the communications cable or down conductor system passed from the wire rope pipeline get final product, also promptly pierce into and pass from the pipeline outlet from the pipeline inlet of wire rope pipeline.So, both can avoid existing communication cable or down conductor system integral body to be exposed to outer defective, shorten the distance of the communications cable or down conductor system again as much as possible, can also utilize the wire rope pipeline to serve as electromagnetic-field-shielded layer, prevent from outwards to produce powerful electromagnetic radiation when down conductor system is struck by lightning electric power under drawing, also avoid the communications cable by external electromagnetic radiated interference signal simultaneously.Simultaneously, be subjected to the protection of wire rope pipeline, the communications cable or the down conductor system that pass the wire rope pipeline are not easy to be damaged by external environment, and be more durable in use.
Compared with the aforementioned existing similar products, multichannel electromagnetism electric field shielding hardware of the present utility model simple and practical, have electromagnetic-field-shielded function, can be a plurality of fixedly connected, can vertically install and also can parallelly install, protect cable and prevent that effectively electromagnetic field from producing and harm.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
