The screening cage of metal structure, range light are in the position within screening cage, and the screening cage is fixed on lamp mast, and the sudden strain of a muscle bar that connects erects
It is directly fixed on screening cage top, described connect dodges bar upper end for pointed structures.
Further, the screening cage is made of top plate, base plate, several pillars arranged vertically, on the pillar
End is fixedly linked with top plate, and the lower rod end is fixedly linked with base plate, and described connect dodges the upper plate that bar is fixed on top plate vertically
On face, the base plate is fixed on lamp mast.
Further, the slab construction that the top plate, base plate are arranged horizontally.
Further, described connect dodges the fixed connection point of bar and top plate and is in the center of top plate upper face.
Further, the top plate is rectangular configuration.
Further, the quantity of the pillar is four, and four pillars respectively correspond four square positions of top plate.
Further, described connect is dodged bar, screening cage and is made of electrically conductive material.
Range light is set the utility model has the beneficial effects that: can prevent from connecing dodging bar and drawing the electromagnetic induction generated after thunder
Standby collateral damage is not influenced, therefore inside range light according to faraday cup principle inside screening cage by the electromagnetic induction for dodging bar is connect
Induced current will not be generated, it is avoided and is damaged because of inductive lightning；More pillars of screening cage constitute a plurality of thunder and lightning and draw lower lead to
Road reduces inductive lightning to the electromagnetic effect of navigation lamp apparatus other on lamp mast；The gap that the branch intercolumniation of screening cage is formed not shadow
The daily maintenance and handling for ringing range light, will not influence the normal operation of its light.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the top view of Fig. 1.
In figure, 1 connects sudden strain of a muscle bar, 2 screening cages, 2a top plate, 2b pillar, 2c base plate, 3 lamp masts, 4 range lights.
Specific embodiment
The present invention will be further described in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of cage lightning protection device peculiar to vessel, including connect and dodge bar 1, it further include the screening cage 2 of all-metal structure,
Range light 4 is in the position within screening cage 2, and screening cage 2 is fixed on lamp mast 3, connects sudden strain of a muscle bar 1 and is fixed on 2 top of screening cage vertically,
It connects and dodges 1 upper end of bar for pointed structures.
Above-mentioned screening cage 2 is made of the pillar 2b that top plate 2a, base plate 2c, four arrange vertically, the upper end pillar 2b and top
Plate 2a is fixedly linked, and the lower end pillar 2b is fixedly linked with base plate 2c, connects sudden strain of a muscle bar 1 and is fixed on the upper face of top plate 2a vertically,
Base plate 2c is fixed on lamp mast 3.
The slab construction that above-mentioned top plate 2a, base plate 2c are arranged horizontally.
Above-mentioned connect dodges the fixed connection point of bar 1 and top plate 2a and is in the center of top plate 2a upper face.
As shown in Fig. 2, above-mentioned top plate 2a is rectangular configuration, the shape of top plate 2a is not limited only to rectangle.Above-mentioned pillar 2b's
Quantity is four, and four pillar 2b respectively correspond four square positions of top plate 2a.The quantity of pillar 2b is not limited only to four,
But the handling of range light should not be influenced.
It is above-mentioned connect dodge bar 1, screening cage 2 is made of conductive stainless steel or copper material, be not limited only to stainless steel or copper
Material can be other conductive materials.
