Abstract

The utility model relates to a flash-grounding device of lighting protection device, in particularly to a flash-grounding device which comprises a pinpoint body, a base spheroid, an adjacent spheroid, a sill bar body, etc. and has the performance of advance discharging, the utility model has more excellent direct lighting flash protective performance than the traditional lighting rod and is provided with the characteristic of Chinese traditional decoration culture; the utility model is suitable for using on the top of ordinary buildings, particularly for using in small area high buildings and structures.

Description

Arrester

The utility model relates to the arrester of direct striking thunder prevention device, particularly arrester.

The arrester that improves the Franklin lightning rod now is existing multiple, and purpose is all in order to improve lightning protection effect and to strengthen attractive in appearance.But the formal construction of these lightning rods lacks certain Chinese traditional architecture decorates cultural features.

The purpose of this utility model provides a kind of improving the scheme of Franklin lightning rod with the lightning rod that certain and Chinese traditional architecture decoration cultural features are combined.

Embodiment of the present utility model is, make so a kind of arrester with metal, by the needle point body, the base spheroid, adjacent spheroid and bottom bar body etc. are partly formed, when operating conditions, it is characterized in that: root diameter (RD) is that the needle point body of Φ 8～Φ 350mm is erect the top, center that is connected in the spheroid group who is connecting with conductor, and protrude from and go up a 20～6000mm above the spheroid most, diameter is that the bottom bar body of Φ 8～Φ 10mm then is connected in this spheroid group's below and protrudes from 10～6000mm below the most next spheroid, the metal gusset piece that it is 2～20mm that the lower end of bottom bar body is connected with the thickness as the usefulness of coupling, its area are 1～20 times of bottom bar body cross section; Base spheroid and adjacent spheroid can all be spherosomes, can all be spheroids also, and the section of crossing ball centre is an ellipsoid, and the semi-minor axis that this is oval and the ratio of semi-major axis are 0.1～1.0; This increases progressively 8%～92% up or down with the spheroid group that conductor is being connected, adjacent spheroid volume, and promptly increment value can just can be born; This is with the spheroid group that conductor is being connected, centre distance L and this two radiuses of a ball sum (R of any adjacent two spheroids ₁+ R ₂) ratio between 0.1～30, two promptly adjacent balls can intersect, join or from; Diameter is that the basic spheroid of Φ 40～Φ 1500mm is the spheroid of volume maximum among the spheroid group, and remaining all is that diameter is the adjacent spheroid of Φ 20～Φ 1000mm, has 1～10.

Accompanying drawing below in conjunction with a kind of embodiment further specifies the utility model.

Schematic views when accompanying drawing is the utility model operating conditions.

The fixing below of the adjacent spheroid (2) of needle point body (1) on end of welding joins mutually with basic spheroid (3), protruding from the bottom bar body metal gusset piece (5) that the lower end of the bottom bar body (4) of basic spheroid (3) below is fixedly welding is downwards being connected by 4 bolts with the tower bar metal gusset piece (6) that is welding on the top of the metal tower body of rod (7), during thunderbolt, lightning current is from needle point body (1) the adjacent spheroid (2) of flowing through, base spheroid (3), bottom bar body (4) and metal gusset piece (5), (6), again through the metal tower body of rod (7), downlead (8) arrives earthing device (9), loose at last and flow into the earth.

The utility model is owing to the spheroid group of needle point body below can play the effect of forward position electrostatic induction preferably and converge the effect of electrostatic charge to the needle point place of needle point body preferably when operating conditions, thereby has in advance a performance of discharge, than conventional lightning conductor the anti-preferably function of attacking directly is arranged, again because sphere volume is not of uniform size, the centre of sphere is apart from differing, can constitute diversified Chinese traditional architecture extraneous adornment cultural features, accompanying drawing is exactly the common single cucurbit in Chinese palaiotype temple roof, the utility model is fit to the buildings in general top and goes up use, and the high constructure and the structures that are particularly suitable for small size use.

Claims

1, the utility model relates to the arrester of direct striking thunder prevention device, arrester particularly, needle point body by the metal making, the base spheroid, adjacent spheroid and bottom bar body etc. are partly formed, it is characterized in that when operating conditions: root diameter (RD) is that the needle point body of Φ 8～Φ 350mm is erect to be connected in the spheroid group's who is connecting with conductor top and to protrude from and gone up a 20～6000mm above the spheroid most, diameter is that the bottom bar body of Φ 8～Φ 110mm then is connected in this spheroid group's below and protrudes from 10～6000mm below the most next spheroid, diameter is that the basic spheroid of Φ 40～Φ 1500mm is the spheroid of volume maximum among the spheroid group, all the other all are that diameter is the adjacent spheroid of Φ 20～Φ 1000mm, have 1～10.

2, arrester according to claim 1 is characterized in that: basic spheroid and adjacent spheroid all are spheroids, and the section of crossing ball centre is an ellipsoid, and the oval semi-minor axis and the ratio of semi-major axis are 0.1～1.0.

3, arrester according to claim 1 is characterized in that: with the spheroid group that conductor is being connected, adjacent spheroid volume increases progressively 8%～92%.

4, arrester according to claim 1 is characterized in that: with the spheroid group that conductor is being connected, two adjacent ball centre are apart from L and this two radiuses of a ball sum (R ₁+ R ₂) ratio between 0.1～30.

5, arrester according to claim 1 is characterized in that: the lower end of bottom bar body is connected with the metal gusset piece of thick a 2～20mm of being, and its area is 1～20 times of bottom bar body cross section.
