Description
Technical field
The utility model belongs to power system security field, relates to ground wire, especially a kind of acousto-optic prior-warning device for ground wire.
Background technology
In annual electric system, all can occur to be with in interruption maintenance operating process ground wire to recover power transmission or mistake plucks ground wire and stops power transmission and cause personal equipment injures and deaths event to occur, the consequence of bringing is severe huge with loss, mainly, because operating personnel's earth wire is placed earthing position or quantity is fuzzy causes, also have the situation that in conventional earthing device (ground wire or grounding switch) and power failure work, ground wire is obscured is existed simultaneously.
By retrieval, find no and close the patent literature that solves ground wire mistake and detain for interrogation topic.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of can clear grasp ground wire position, distinguish ground wire in work and the acousto-optic prior-warning device for ground wire of conventional earthing device.
The technical scheme that the utility model technical solution problem adopts is:
A kind of acousto-optic prior-warning device for ground wire; comprise audible-visual annunciator, guard box, insulating mat and earthing clamp; at the inside of guard box setting-in one audible-visual annunciator; outer-rear end face middle part at guard box is fixedly mounted with an insulating mat; be fixedly mounted with an earthing clamp in the outer face of insulating mat; in the both sides, inside of guard box, mirror image symmetry is respectively fixedly mounted with a bracing frame; described audible-visual annunciator is inlaid between two bracing frames; in the upper surface of audible-visual annunciator, one snap switch is installed, this snap switch passes the end face of guard box.
And hinge fills a chamber door in the front side of guard box, this chamber door is by latch and guard box locking.
And, between snap switch top and guard box end face, be coaxially fixedly mounted with an O-ring seal.
And, be shaped with multiple louvers the both sides of guard box end face is uniform respectively.
Advantage of the present utility model and good effect are:
1, this acousto-optic prior-warning device is enclosed within the side of ground wire near equipment, when use, audible-visual annunciator sends strong flash of light and high pitch early warning at intermittence sound, prompting staff still has ground wire hitching, closes audible-visual annunciator and comprehensively can effectively avoid accident to occur in conjunction with ground wire quantity again after ground wire takes off.
2, this acousto-optic prior-warning device has low power consuming, chargeable, high light high pitch performance, and in operational zone, can be found daytime.
3, this acousto-optic prior-warning device is respectively fixedly mounted with a bracing frame in the both sides, inside of guard box mirror image symmetry, and audible-visual annunciator is inlaid between two bracing frames, and this two bracing frame is fixedly clamped, prevents that by audible-visual annunciator it from rocking in guard box.
4, this acousto-optic prior-warning device is fixedly mounted with an insulating mat at the outer-rear end face middle part of guard box, and this insulating mat can prevent that induced electricity from puncturing audible-visual annunciator.
5, the guard box of this acousto-optic prior-warning device is made up of transparent insulation material, makes the high light of audible-visual annunciator can see through guard box, is shaped with multiple louvers the both sides of guard box end face is uniform respectively, the high pitch of audible-visual annunciator spread by louver.
Brief description of the drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the right view of Fig. 1;
Fig. 4 is that the A-A of Fig. 3 is to cross-sectional view.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of acousto-optic prior-warning device for ground wire; comprise audible-visual annunciator 9, guard box 3, insulating mat 6 and earthing clamp 5; at the inside of guard box setting-in one audible-visual annunciator, be fixedly mounted with an insulating mat at the outer-rear end face middle part of guard box, be fixedly mounted with an earthing clamp in the outer face of insulating mat.
Described audible-visual annunciator has low power consuming, chargeable, high light high pitch performance, and in operational zone, can be found daytime, and the inner structure of this audible-visual annunciator is prior art, does not do tired stating at this.
For the ease of the installation of audible-visual annunciator and be audible-visual annunciator charging, in the front side of guard box, hinge fills a chamber door 1, and this chamber door is by latch 4 and guard box locking.
In the both sides, inside of guard box, mirror image symmetry is respectively fixedly mounted with a bracing frame 10, and described audible-visual annunciator is inlaid between two bracing frames, and this two bracing frame is fixedly clamped, prevents that by audible-visual annunciator it from rocking in guard box.
One snap switch 2 is installed in the upper surface of audible-visual annunciator, and this snap switch passes the end face of guard box, is coaxially fixedly mounted with an O-ring seal 8 between snap switch top and guard box end face.
Described guard box is made up of transparent insulation material, makes the high light of audible-visual annunciator can see through guard box, is shaped with multiple louvers 7 the both sides of guard box end face is uniform respectively, the high pitch of audible-visual annunciator spread by louver.
The practical problems being not quite similar for different electric pressure ground wire fineness degrees, earthing clamp can be designed to all size to meet fixing acousto-optic prior-warning device.
Using method of the present utility model is:
Acousto-optic prior-warning device is enclosed within to the side (the opposite side ground connection of ground wire) of ground wire near equipment, press snap switch, audible-visual annunciator sends strong flash of light and high pitch early warning at intermittence sound, prompting staff still has ground wire hitching, closes audible-visual annunciator and comprehensively can effectively avoid accident to occur in conjunction with ground wire quantity again after ground wire takes off.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of utility model design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
