Abstract
The utility model discloses an automatic cable well danger warning device and relates to a cable well danger warning device. The automatic cable well danger warning device comprises a warning rod, a support, two torsional springs and a supporting rod, the support is fixed on a well wall below a wellhead of a cable well, the supporting rod penetrates through spring bodies of the two torsional springs and the lower end of the warning rod and is arranged on the support, the two torsional springs are respectively positioned at the two sides of the lower end of the warning rod and are consistent in mounting direction, one end of each torsional spring is clamped on a mounting plane of the support, the other end of each torsional spring is of an L-shaped structure, each L-shaped structural tail end is vertical to the axis of the warning rod and is inserted into the lower end of the warning rod, and the upper end of the warning rod protrudes from the ground and is parallel to the well wall. The automatic cable well danger warning device has the advantages that the structure is simple, the reliability is high, and automatic control and repeated use are realized; four states of opening, closing, missing and jumping of the wellhead can be automatically warned, so that the potential safety hazard caused by missing of the wellhead is completely eradicated.
Description
Technical field
The utility model relates to the dangerous alarming device of a kind of cable shaft, specifically the dangerous automatic warning device of a kind of cable shaft.
Background technology
Cable shaft is to coordinate underground pipeline, and effective communal facility of using as remote buried power supply plays an important role in the installation and maintenance of circuit; But in actual use, the well lid of cable shaft is stolen, damaged, disappearance is damaged phenomenon and again and again occurred, stolen, disappearance or damaged that well lid occurs, do not find in time or process, may injure pedestrian or vehicle on the one hand, even can there is causing death's accident in serious, such news report is also often reported in media; Also badly influence the use of road and the safe handling of electric power cable, especially in rainy and low laying areas, in the well of down-hole, equipment may be soaked and lose efficacy and corrosion by water logging, has caused huge economic loss to public administrative departments and power system simultaneously.
How stolen, the damaged deficient phenomena of well lid is carried out to rapid automatic warning, allow pedestrian and relevant departments find in time, avoid occurring unexpected traffic accident, avoid down-hole facility stolen or flooded bubble and lost efficacy simultaneously, this is a problem of puzzlement power system relevant departments always.
Summary of the invention
The utility model provides a kind of cable shaft dangerous automatic warning device, when well lid is stolen, during damaged disappearance, alarm rod auto-extending walling crib seat, with its gay colours, play obvious warning function by day, the in the situation that of night or insufficient light, its bright reflecting effect can strengthen people's recognition capability effectively, sees target clearly; When well lid is in place completely, automatic safe alarm rod is in preparation state.
The utility model is realized with following technical scheme: the dangerous automatic warning device of a kind of cable shaft, comprises alarm rod, support, torque spring and support bar; Described torque spring has two; Described support is fixed on the borehole wall of well cover of cable well below; Described support bar is rack-mount through the spring body of two torque springs and the lower end of alarm rod, both sides, lower end and installation direction that two torque springs lay respectively at alarm rod are consistent, one end of each torque spring is stuck on the mounting plane of support, the other end is L-type structure, the axis of L-type structure end and alarm rod is vertical and insert alarm rod lower end, and the upper end of alarm rod protrudes from ground parallel with the borehole wall.
The beneficial effects of the utility model are: to the unlatching of well lid, close, lack, jump four kinds of states such as lid and carry out automatic warning, stop the potential safety hazard causing due to manhole cover loss.Simple in structure, reliability is high, and visibility is high, and can automatically control and reuse, and avoids to greatest extent the unexpected injury that causes due to cable manhole cover loss and the generation of security incident, reduces the loss of casualties and property, guarantees the safety of electric power system.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation when lockup state;
Fig. 2 is B-B sectional view in Fig. 1;
Fig. 3 is the utility model structural representation when alert status.
In figure: 1, well lid; 2, alarm rod; 3, support; 4, torque spring; 5, support bar.
The specific embodiment
As depicted in figs. 1 and 2, the dangerous automatic warning device of a kind of cable shaft comprises alarm rod 2, support 3, torque spring 4 and support bar 5; Described torque spring 4 has two; Described support 3 is fixed on the well cover of cable well 1 below borehole wall; Described support bar 5 is arranged on support 3 through the spring body of two torque springs 4 and the lower end of alarm rod 2, both sides, lower end and installation direction that two torque springs 4 lay respectively at alarm rod 2 are consistent, one end of each torque spring 4 is stuck on the mounting plane of support 3, the other end is L-type structure, and the axis of L-type structure end and alarm rod 2 is vertical and insert alarm rod 2 lower ends.
In the present embodiment, be provided with two installing holes on the mounting plane of support 3, by two expansion bolts, be arranged on borehole wall upper end near well cover of cable well 1, under the effect of torque spring 4, the upper end of alarm rod protrudes from ground parallel with the borehole wall.
In the lower end of alarm rod 2, be provided with the connecting hole matching with torque spring 4, connecting hole is two, and the axis of connecting hole is perpendicular to the axis of alarm rod 2, and during installation, L-type structure end penetrates in connecting hole.
Described alarm rod 2 scribbles the column of reflectorized material for outer round surface.Owing to scribbling reflective look on alarm rod, can play reminder alerting effect;
Described column is plastic pipe, and plastic pipe is lightweight, can not injure pedestrian and vehicle, and safety is good.
For convenient, install, described support bar 5 adopts bolt.
As shown in Figure 1, when well lid 1 is arranged on well seat, need to overcome spring force alarm rod 2 to pressing to and borehole wall near normal, now torque spring 4 is in twisting states, twisting force is between support 3 and alarm rod 2, because support 3 is fixed on the cable shaft borehole wall, so the power of alarm rod 2 oriented upper resiliences, but because well lid 1 is pressed on alarm rod 2, make alarm rod 2 continue to keep and borehole wall near normal in lockup state; Enter readiness for operation.
As shown in Figure 3, when well lid 1 leaves well seat, the power that well lid 1 is pressed on alarm rod 2 disappears, and due to the acting in conjunction of two torque springs 4, makes alarm rod 2 protrude from ground, owing to scribbling reflective look on alarm rod 2, can play reminder alerting effect; Adopt equidirectional two torque springs 4, and be not just placed on the both sides of alarm rod 2 lower ends, both increased the torsion of spring, be conducive to again the balance of alarm rod 2.
The utility model not only can, for cable shaft, also can be used on the urban operating mechanisms such as sink hole, communication well, plumbing well.
