Abstract
The utility model relates to a street light pole inclining protective device which comprises a metal cylinder which is parallel to a street light pole, wherein the bottom end of the metal cylinder is sealed, and the top end of the metal cylinder is open. An insulating plug is installed in the opening in the top end of the metal cylinder, a metal rod penetrates through the insulating plug, and the bottom end of the metal rod is hinged to a metal stick. The street light pole inclining protective device further comprises a relay and a power source supplying electricity to a coil of the relay. A normally-closed contact of the relay is connected to a power supply circuit of a street light in series, and a switch formed by the metal stick and the metal cylinder is connected to a power supplying loop of the coil of the relay in series. The function of cutting down the power supply circuit when the street light pole inclines is achieved through the very simple structure, the whole street light pole inclining protective device is simple in structure and convenient to install and use, and the probability of electric shock accidents is reduced.
Description
Technical field
The utility model relates to a kind of light pole inclination protector.
Background technology
Light pole mostly is the tubulose of hollow, is hidden in the hollow cavity of lamp stand for the branch feeding circuit of the street lamp power supply, road lamp power supply to the lamp stand top, and total supply line is embedded in underground, and the branch feeding connection is to total supply line.Light pole phenomenon easily occurs tilting even to collapse using for a long time or run into after clashing, if continuing the use meeting, the light pole tilted brings potential safety hazard to Pedestrians and vehicles on surrounding buildings or road, in addition, if the light pole transition is tilted or collapsed, once falling to ground, charged branch feeding circuit very likely causes electric shock accidents.
The utility model content
The technical problems to be solved in the utility model is to provide a kind ofly can cut off the light pole inclination protector of street lamp power supply, road lamp power supply in time when the light pole over-tilting, and this apparatus structure is simple, easy to use, avoided the security incident that tilts or collapse and cause because of light pole.
For solving the problems of the technologies described above, the design feature of light pole inclination protector of the present utility model is to comprise that one be arranged in parallel with light pole and the bottom sealing, the metallic cylinder that top is uncovered, on the top of metallic cylinder is uncovered, insulating plug is installed, be coated with a metallic rod on insulating plug, the bottom of metallic rod is hinged with metal bar, described protector also comprises a relay and the power supply of powering to this relay coil, the normally-closed contact of relay is connected in the supply line of street lamp, metal bar and metallic cylinder form in the current supply circuit that a switch series is associated in relay coil.
The bottom of described metallic rod is a ball-and-socket, and the top of metal bar is the bulb coordinated with above-mentioned ball-and-socket.
The bottom of described light pole offers power slot, and power supply is arranged in power slot.
Be connected with an annular anchor ear on described metallic cylinder, this annular anchor ear is mounted by means of bolts on light pole.
The bottom of described metal bar is taper.
Adopt said structure, when light pole during in normal vertically state, metal bar and metallic cylinder insulation, when light pole tilts, metal bar still keeps vertical state under the effect of gravity, metallic cylinder is followed light pole and is presented certain angle of inclination, while tilting to a certain degree, metal bar contacts with metallic cylinder, thereby it is electric to make the coil of relay obtain, and the normally-closed contact of relay is opened, thereby cut off the supply line of street lamp, the electric shock accidents caused while having avoided street lamp to topple over.Visible, the utility model has realized cutting off when light pole is toppled over the function of street lamp power supply, road lamp power supply circuit by foolproof structure, and whole apparatus structure is simple, easy to install, has reduced the electric shock accidents odds.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, light pole inclination protector of the present utility model comprises that one be arranged in parallel with light pole 1 and bottom sealing, the uncovered metallic cylinder 2 in top, be connected with an annular anchor ear 11 on metallic cylinder 2, this annular anchor ear 11 is mounted by means of bolts on light pole 1.Insulating plug 3 is installed on the top of metallic cylinder 2 is uncovered, be coated with a metallic rod 4 on insulating plug 3, the bottom of metallic rod 4 is hinged with metal bar 5, this protector also comprises a relay 6 and the power supply 7 of powering to this relay coil 61, the normally-closed contact 62 of relay 6 is connected in the supply line 9 of street lamp 8, and metal bar 5 and metallic cylinder 2 form a switch series and be associated in the current supply circuit of relay coil 61.Wherein, power supply 7 can adopt Xu to point out, and the bottom of light pole 1 offers power slot 10, and power supply 7 is arranged in power slot 10.
Adopt said structure, when light pole 1 during in normal vertically state, metal bar 5 and metallic cylinder 2 insulation, when light pole 1 tilts, metal bar 5 still keeps vertical state under the effect of gravity, metallic cylinder 2 is followed light pole 1 and is presented certain angle of inclination, while tilting to a certain degree, metal bar 5 contacts with metallic cylinder 2, thereby the current supply circuit of turn-on relay coil 61, relay coil 61 obtains electric, and the normally-closed contact 62 of relay 6 is opened, thereby cuts off the supply line 9 of street lamp 8.
With reference to accompanying drawing, the articulated structure for metallic rod 4 with metal bar 5, the utility model preferably: the bottom of metallic rod 4 is a ball-and-socket, and the top of metal bar 5 is the bulb coordinated with above-mentioned ball-and-socket.The structure that adopts the bulb ball-and-socket to coordinate, make metal bar 5 rotate more smooth and easyly around metallic rod 4 bottoms.In addition, more reliable for what when metallic cylinder 2 tilts, metal bar 5 bottoms were electrically connected to metallic cylinder 2, the bottom of metal bar 5 is taper.
In sum, the utility model is not limited to the above-mentioned specific embodiment.Those skilled in the art, under the prerequisite that does not break away from spirit and scope of the present utility model, can do some changes and modification.Protection domain of the present utility model should be as the criterion with claim of the present utility model.
