Abstract

The utility model relates to a new type lightning arrester with split head voltage-sharing type against around shocking, compising seven parts; a centre needle, a split voltage-sharing needle, an against around shocking arrester, a voltage-sharing ring, a support frame, a grounding down lead and a grounding device. The new type lightning arrester with split head voltage-sharing against around shocking is characterized in that the split voltage-sharing needle is higher than or equal to the centre needle; the split voltage-sharing needle, the against around shocking arrester and the voltage-sharing ring are mutually fixedly connected; the included angle between the against around shocking arrester and the split voltage-sharing needle is greater than 0 degree and is smaller than 90 degrees . The new type lightning arrester has the functions of against direct stroke lightning and against around shocking lightning; the new type lightning arrester also has convenient design, manufacture and construction, low price and long service life.

Description

Novel head split voltage-sharing anti-mine lightning rod

Title of the present utility model is: novel head split voltage-sharing anti-mine lightning rod.

The utility model is used for the shocking preventing technology field of various constructions of structures.

The major defect of existing lightning rod is to attract, to tackle direct lightning strike, can not attract, tackle around shocking, promptly can only direct striking thunder prevention, can not anti-mine, thus cause some protected objects to suffer shielding damage to crops caused by thunder.

The purpose of this utility model is that a kind of novel head split voltage-sharing anti-mine lightning rod will be provided, and this novel lightning rod can overcome the existing existing above-mentioned defective of lightning rod, can direct striking thunder prevention, and again can anti-mine.

Design of the present utility model is to realize like this, seven parts such as it comprises center needle, divide equal pressing, anti-mine pin, grading ring, support, down conductor, earthing device, it is characterized in that dividing equal pressing is higher than or etc. be higher than center needle, divide equal pressing, anti-mine pin and grading ring Joint, anti-mine pin and the angle of division between the equal pressing greater than 0 °, less than 90 °.At thunderstorm weather, center needle, the equal pressing of division play a part to attract, the interception direct lightning strike, and the anti-mine pin plays a part to attract, the interception around shocking.

Therefore, than existing lightning rod, the utlity model has following remarkable advantage:

1, can under the constant situation of lightning rod protection scope, make lightning rod have direct striking thunder prevention and anti-mine function, prevent that protected object from suffering shielding damage to crops caused by thunder, more safe and reliable.

2, design, manufacturing, easy construction.

3, can be applied to the lightning protection of various constructions of structures, have wide range of applications, project cost is low, long service life.

Below in conjunction with accompanying drawing the utility model is specifically described.

Fig. 1 is an organigram of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is an embodiment application state schematic diagram of the present utility model.

With reference to Fig. 1,1 is center needle among the figure, the 2nd, divide equal pressing, and the 3rd, anti-mine pin, the 4th, grading ring, the 5th, support, the 6th, down conductor, the 7th, earthing device.

With reference to Fig. 2,1 is center needle among the figure, the 2nd, divide equal pressing, and the 3rd, anti-mine pin, the 4th, grading ring.

With reference to Fig. 3,1 is center needle among the figure, the 2nd, divide equal pressing, and the 3rd, anti-mine pin, the 4th, grading ring, the 5th, support, the 6th, down conductor, the 7th, earthing device, the 8th, high-rise.

The equal pressing of division of the present utility model can be taken as 2～60 pins, divide equal pressing around center needle by symmetric arrangement, the distance of separation that divides equal pressing and center needle can be taken as 0.2～20.0 meter, divides the height that equal pressing exceeds center needle and can be taken as 0.1～3.0 meter; The anti-mine pin can be taken as 2～60 pins, presses symmetric arrangement around grading ring.The center needle of this novel anti-mine lightning rod, divide equal pressing, anti-mine pin, grading ring etc. and can adopt manufacturings such as steel, stainless steel or aluminium alloy.
