Description

Combine lightning rod

Technical field

A kind of combination lightning rod is the utility model is related to, belongs to and is related to lightning-protecting engineering field.

Background technology

Lightning rod is the device for protecting building, tall and big trees etc. to avoid thunderbolt, and one is installed on protected object top

Root arrester, connected with wire up to specification with being embedded in the aerial drainage earth mat of underground.

When thundercloud discharge is close to ground, it is distorted ground electric field, and internal field's collection is formed on the top of lightning rod In space, to influence the developing direction of lightning leader electric discharge, guiding thunder and lightning to lightning-arrest needle-discharging, then by down conductor and Thunder and lightning is introduced the earth by earthing or grounding means, so that protected object body exempts from thunderbolt.High-rise because its height is higher, therefore by Risk to thunderbolt is also larger, but the more existing lightning rod for high-rise, and particularly some are used for high-rise Its structure of the lightning rod of power circuit facility is simultaneously not content with current lightning-arrest requirement.

Utility model content

Combination lightning rod provided by the utility model, convenient disassembly, is easily assembled, and stability is good, and service life is also longer.

To reach above-mentioned purpose, the technical solution adopted in the utility model is：Combine lightning rod, including support, lightning-arrest ball With the lightning rod on lightning-arrest ball, its feature is mounted in cradle top, described lightning rod described lightning-arrest ball is removable Upper that grading ring component is removably housed, described grading ring component is included in the middle part of horizontally disposed lower uniform pressure ring and lightning rod The sleeve pipe and the collection depression bar of connection lower uniform pressure ring and sleeve pipe of Demountable assembling.

Preferably, the top of described lower uniform pressure ring has the upper grading ring axially aligned with lower uniform pressure ring, and described is upper Grading ring is connected with lower uniform pressure ring by connecting rod.

Preferably, there is the equal pressing vertically set on upper grading ring.

Preferably, the middle part of described lightning rod has conical external screw thread section, has on described internal surface of sleeve pipe and taper The conical internal thread that external thread section coordinates, sleeve pipe is coordinated by screw thread to be locked at the middle part of lightning rod.

Preferably, the top of described support has screwed hole, and the bottom of described lightning-arrest ball has to be coordinated with screwed hole Screw rod.

Combination lightning rod medium-height trestle of the present utility model and lightning-arrest ball are dismantled and assembled assembling, and lightning rod is with grading ring component Detachable assembling, makes that the structure of combination lightning rod is simple, is easily assembled, and transport, dismounting and ordinary maintenance it is all quite convenient, furthermore The combination lightning rod is lightning-arrest using lightning-arrest ball, lightning rod, grading ring and the combination of equal pressing, and lightning protection reliability is higher, can be effective The electric power facility on skyscraper spy is protected, efficiency of taking shelter from the thunder is notable, practical.

Fig. 3 is the structural representation of lightning-arrest ball and lightning rod,

Fig. 4 is the structural representation of support.

Embodiment

The utility model will be further described by accompanying drawing 1-4 and embodiment below.

As illustrated, combination lightning rod, including support 1, lightning-arrest ball 2 and the lightning rod 3 on lightning-arrest ball 2, its feature It is removable at the top of support 1 in described lightning-arrest ball 2, grading ring component 4 removably is housed on described lightning rod 3, Described grading ring component 4 includes the sleeve pipe 42 of horizontally disposed lower uniform pressure ring 41 and the middle part Demountable assembling of lightning rod 3 and connected Connect the collection depression bar 43 of lower uniform pressure ring 41 and sleeve pipe 42.

The top of described lower uniform pressure ring 41 has the upper grading ring 44 axially aligned with lower uniform pressure ring 41, and described is upper equal Pressure ring 44 and lower uniform pressure ring 41 are connected by connecting rod 45.There is the equal pressing 46 vertically set on described upper grading ring 44. The middle part of described lightning rod 3 has conical external screw thread section 31, has and conical external screw thread section 31 on the described inwall of sleeve pipe 42 The conical internal thread of cooperation, sleeve pipe 42 is coordinated by screw thread to be locked at the middle part of lightning rod 3.The top of described support 1 has Screwed hole 11, the bottom of described lightning-arrest ball 2 have the screw rod 21 coordinated with screwed hole 11.

When combination of the above lightning rod is installed, first fills support 1 and be fixed on high-rise power circuit facility, and Support 1 is connected by being grounded with earthing or grounding means, then the lightning-arrest ball 2 with lightning rod 3 is assembled in the top of support 1, it Afterwards, then by sleeve pipe 4 screw in the conical external screw thread section 31 of lightning rod 3, make uniform pressure ring assembly 4 on lightning rod 3, by equal Pressure ring assembly prevents thunder and lightning flank attack, effectively prevents thunder and lightning from attacking directly by lightning rod 3 and equal pressing 46.

Combination lightning rod medium-height trestle 1 above is that screw thread coordinates assembling with lightning-arrest ball 2, and lightning rod 3 is with grading ring component 4 Internal and external threads coordinate assembling, make that the structure of combination lightning rod is simple, is easily assembled, and transport, dismounting and ordinary maintenance it is all quite square Just, furthermore the combination lightning rod is kept away using lightning-arrest ball 2, lightning rod 3, lower uniform pressure ring 41, upper grading ring 44, the combination of equal pressing 46 Thunder, lightning protection reliability is higher, the electric power facility that can be effectively protected on skyscraper spy, and efficiency of taking shelter from the thunder is notable, practical.

Completely description is carried out to the technical scheme of the utility model embodiment, it is necessary to which explanation is to be retouched above in association with accompanying drawing The embodiment stated is only the utility model part of the embodiment, is made common based on the embodiment in the utility model, this area The every other embodiment that technical staff is obtained on the premise of creative work is not made, belong to the utility model guarantor The scope of shield.
