Abstract
The utility model discloses a higher static electricity discharge device of fail safe nature. Including casing, positive pole and negative pole, the casing comprises square pipe, pullover and loudspeaker mouth, and it is all as an organic whole with pullover welding that both ends are managed in the side, and pullover outer end is as an organic whole with loudspeaker mouth spiro union, and anodal work with the negative pole holds square intraductal, and the anodal other end with the negative pole is worn out from different loudspeaker mouths respectively, is equipped with the button on manage the side, and the lower extreme of pressing the button is stretched at fang guanzhong to be located anodal top, the negative pole is located anodal below. Because the electric spark that anodal and negative pole all at the casing in, produced when discharging restricts in the casing space, can not contact with the external world, played anti -detonation's possibility, the security of operating of discharging improves greatly.
Description
Technical field
The utility model relates to a kind of static release device.
Background technology
Current China's coal-mine major part has the danger of gas and coal-dust explosion, when the gas in underground air or coal dust reach explosion ratio and incendiary source meets certain energy, gas or coal-dust explosion will occur.When electrical network generation single-line ground or equipment occur single-phase touch shell time, will electric spark be produced at earth point, if now electric spark has enough energy, just may light gas or coal dust.Down-hole electrician is when normal operation, often need electric equipment power failure, electrical verification, electric discharge, first be survey this place's gas density during electric discharge, when gas density is below 1%, can electrical verification, be connected on earth bus or auxiliary earthed busbar with electrical discharge wire one end again, other end cutting pliers are picked up and are needed discharge power supply contact discharge.This kind of discharge mode, needs manual operation, and electric discharge place exposes to the open air at open space, and when gas density and dust concentration instability, very easily explosion caused, the fail safe of operation is extremely unreliable.
Summary of the invention
The purpose of this utility model is to provide the higher static release device of a kind of security reliability.
The technical solution of the utility model is: comprise housing, positive pole and negative pole, described housing is by square tube, pullover and loudspeaker nozzle forms, square tube two ends are all welded as a whole with pullover, pullover outer end and loudspeaker nozzle are spirally connected and are integrated, the working end of positive pole and negative pole is through in square tube, the other end of positive pole and negative pole passes from different loudspeaker nozzles respectively, square tube is provided with button, button lower end is stretched in square tube, and be positioned at above positive pole, negative pole is positioned at below positive pole, described button is by button spindle, button cap and spring composition, button spindle bottom is provided with boss and this boss is positioned at square tube, spring housing is on button spindle and be positioned at outside square tube, button cap is spun on button spindle top.
Positive bracket and negative bracket is provided with in square tube.
The utility model adopts shell structure, positive pole and negative pole are all in housing, that is: exposed metallic object positive pole and negative pole are all in the housing of sealing, therefore, the electric spark produced during electric discharge is limited in shell space, can not with extraneous contact, serve prevent explode possibility, the fail safe of discharge operation improves greatly.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, but does not form any restriction of the present utility model.Shown in Fig. 1, Fig. 2 and Fig. 3, the utility model comprises housing, positive pole 3 and negative pole 4, described housing by square tube 7, pullover 2 and loudspeaker nozzle 1 form, square tube 7 two ends are all welded as a whole with pullover 2, pullover 2 outer ends and loudspeaker nozzle 1 are spirally connected and are integrated, the working end of positive pole 3 and negative pole 4 is through in square tube 7, and the other end of positive pole 3 and negative pole 4 passes from different loudspeaker nozzles 1 respectively.Shown in Fig. 4 and Fig. 5, square tube 7 is provided with button 5, button 5 lower end is stretched in square tube 7, and be positioned at above positive pole 3, negative pole 4 is positioned at below positive pole 3, and described button 5 is made up of button spindle, button cap and spring 6, and button spindle bottom is provided with boss and this boss is positioned at square tube 7, spring 6 to be enclosed within button spindle and to be positioned at outside square tube 7, and button cap is spun on button spindle top.Be provided with positive bracket 9 and negative bracket 8 in square tube 7, positive pole 3 is stuck in the groove of positive bracket 9, and negative pole 4 is stuck in the groove of negative bracket 8.After above-mentioned installation, ensure from loudspeaker nozzle 1 draw positive pole 3 go between and negative pole 4 lead-in wire will with loudspeaker nozzle 1 good seal, good seal is wanted in each connecting portion of housing and movable cooperation place.The insulation property of housing and button 5 will reach corresponding technical requirement.
Operating process is as follows: during electric discharge, button press 5, and button 5 moves downward and Compress Spring 6, pushes down positive pole 3 and moves to negative pole 4, until positive pole 3 contacts with negative pole 4, complete electric discharge bottom button 5.After having discharged, release button 5, under the effect of spring 6, button spindle resets, for subsequent operation is got ready.
