The utility model discloses a static storehouse subassembly directly grounded of filler metal liquid, ground resistance is little arc discharge can not to appear at 15m omega, and disappearance induction reactance causes the condition of ground resistance grow, long service life, adopt novel base support body fixed firm, the ground wire retaining ring in the base support body effectively prevents ground wire slippage ground wire storehouse.
Description
Technical field
The utility model relates to a kind of earth system.Particularly relate to a kind of telescopic floating roof tank earth system.
Background technology
What the domestic and international telescopic floating roof tank ground connection of similar type all adopted at present is carbon brush type ground connection and spiral copper alloy spring formula ground connection, easily arc discharge is there is in carbon brush type at high potential and high electric current, easily there is larger induction reactance at high potential and high electric current in helical spring type ground connection, and grounding resistance is at 20--30m Ω;
The method of patent No. ZL02131455.1 eliminating secondary arc by floater and device thereof, disclose a kind of earth system, and this device finds still there are the problems referred to above in long-term practice.
Summary of the invention
The utility model provides a kind of telescopic floating roof tank earth system for the defect of prior art, its object for improve further carbon brush type ground connection high potential and high current impedance comparatively large, easily there is the situation of arc discharge.
The utility model is for realizing above object, adopt following scheme: a kind of telescopic floating roof tank earth system, comprise tank body, tank support, floating plate, ground wire and earth system, this earth system comprises fixed pedestal axle and is located at the spring storehouse assembly on fixed pedestal axle successively, ground wire storehouse assembly and electrostatic bin assembly, wherein ground wire storehouse assembly to be rolled with fixed pedestal axle by ball bearing of main shaft and is connected, this ground wire is wire-wrapped in the assembly of ground wire storehouse, its one end connects floating plate, the described ground wire other end is connected in electrostatic bin assembly, this electrostatic bin assembly comprises the cylindricality storehouse be connected with spring storehouse assembly and fixed pedestal sealing, metal liquid is provided with in this cylindricality storehouse.
Preferably, also comprise a stainless pedestal support body, this pedestal support body comprises the engagement plate of the roller support of " L " type, the ground wire retaining ring of " U " type and " C " type for being connected with tank support, " L " type straight angle end of this roller support and the U of ground wire retaining ring " type end wall one; " L " type turning terminal screw of this roller support is fixed on engagement plate; wherein engagement plate one side wall length of " C " type is greater than another side wall length, and larger sidewall is provided with linking screw.
Preferably, be provided with metal liquid in this cylindricality storehouse and be preferably mercury.
, there is not the situation that induction reactance causes grounding resistance and becomes large, long service life in the beneficial effects of the utility model: the utility model adopts fills the direct ground connection of electrostatic bin assembly of metal liquid, and grounding resistance is little there will not be arc discharge at 15m Ω; Adopt the fixation of novel pedestal support body, the ground wire retaining ring in pedestal support body effectively prevents ground wire slippage ground wire storehouse; The utility model can solve petroleum system large-scale floating roof formula petrol storage tank very well and to be struck by lightning safety problem on fire, has the advantages that safety is high, cost is low and easy to operate.
