Abstract
The utility model relates to a lightning protection net, compising a lightning protection wire cross cable system, a leading-in wire and a grounding device. The lightning protection wire cross cable system is composed of a forward direction cable 1, a reverse direction cable 2 and an edge member; the whole cable system forms a negative Gaussian curvature saddle surface, and the cross nodes of the cross cable system are connected by the conductive clamping plates. Because the utility model adopts the lightning protection wire cross cable system of the negative Gaussian curvature saddle surface, the problem of the middle part of the lightning protection net drooping is better solve. The lightning protection net has good appearance and safe and reliable structure, and can be used for the lightning protection of large sized stadiums, squares, ports, docks, oil storages, etc.
Description
Technical field
The utility model relates to a kind of lightning protection facility, relates in particular to the lightning conduction in the open-air places of large tracts of land such as being used for coliseum, square, port and pier, oil depot district.
Background technology
Common lightening protection installation has lightning rod, lightning conducter; but large-scale place such as being difficult in the middle of the stadium etc. installing or can not backed place, have just usually exceeded the protection range of lightning rod and lightning conducter at the zone line in place; therefore in thundery sky, very easily cause the accident of thunderbolt.For this reason, building a lightning conduction in the place of spaciousnesses such as stadium is the ten minutes needs.The lightning conduction of present use is generally the curved surface of positive gauss curvature, when being used for large-scale place, because span is very big, lightning conduction is under the effect of deadweight, the sag at its middle part is very big, this just usually has influence on the use in place and attractive in appearance, and also there is very big difficulty in this lightning conduction at the mechanics design aspect.
Summary of the invention
In order to solve above problem, the utility model provides a kind of have good lightning-arrest performance, the reliable lightning conduction of structural safety.
The utility model is a kind of lightning conduction, it is made up of lightning conducter intersection rope system, lead-in and earthing device, lightning conducter intersection rope system is made up of forward rope, reverse rope and edge member, the forward rope intersects mutually with reverse rope and then is connected with edge member, the saddle surface of forming negative gauss curvature, described forward rope, reverse rope and edge member are the favorable conductive material.
Forward rope and reverse rope are anchored at respectively on the edge member, and edge member is collar tie beam or flexible edge's drag-line of rigidity, and it is anchored on the support of building the roof or setting up separately.Lightning conducter intersect rope be the forward rope and oppositely the crossover node of rope adopt the conduction clamping plate to be connected or adopt the welding manner connection.The conduction clamping plate are made up of train wheel bridge and lower plate, and train wheel bridge and lower plate are respectively equipped with groove, and two grooves become the X-shape setting, and train wheel bridge is in the same place by bolt with lower plate.Also be provided with simultaneously earthing device on the ground, lightning conducter intersection rope system is connected with earthing device by lead-in.
Above-mentioned utility model owing to adopted negative gauss curvature saddle surface lightning conducter intersection rope system, has solved lightning conduction preferably owing to deadweight causes the sagging problem in middle part, good looking appearance.And its forward rope and reverse rope have applied prestressing force when mounted, and crossover node all adopts the conduction clamping plate to connect, and perhaps welding manner connects, and structural safety is reliable.It is lightning-arrest that it goes for places such as large-scale stadium, square, port and pier, oil depot.

Structural representation when Fig. 2 is the utility model edge member for flexible edge's drag-line;
Fig. 3 is the structural representation of conduction clamping plate 12 among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done a detailed description.
As shown in figures 1 and 3, the utility model is made up of lightning conducter intersection rope system, lead-in and earthing device, and lightning conducter intersection rope system is made up of forward rope 1, reverse rope 2 and rigidity collar tie beam 3.Get some cable wires, they are applied certain prestressing force, as forward rope 1 and reverse rope 2.Forward rope 1 is designed to sagging shape, and the height of middle rope bearing is designed to maximum, to limit rope direction height of support parabolically track descend, then with reverse rope 2 left-hand threads on forward rope 1, constitute a negative gauss curvature saddle surface.
As shown in Figure 2, the utility model is made up of lightning conducter intersection rope system, lead-in and earthing device, and lightning conducter intersection rope system is made up of forward rope 5, reverse rope 8 and flexible edge's drag-line 7.Get some cable wires, they are applied certain prestressing force, as forward rope 5 and reverse rope 8.Forward rope 5 is designed to sagging shape, and the height of middle rope bearing is designed to maximum, to the track decline parabolically of limit rope direction height of support, then reverse rope anti-8 is buckled on the forward rope 5, constitutes a negative gauss curvature saddle surface.
Other features of present embodiment are as described in the embodiment 1.
