Description
Technical Field
The utility model belongs to the technical field of traffic signal lamp, specifically speaking especially relates to a traffic signal lamp for tunnel entrance.
Background
Traffic lights are a traffic control facility usually installed at intersections or other special places to assign the right of way to drivers and pedestrians, and control their movement and turning. The traffic signal lamps are mainly divided into motor vehicle signal lamps, non-motor vehicle signal lamps, pedestrian crossing signal lamps, lane signal lamps, direction indicating signal lamps and flashing warning signal lamps.
In the case of a traffic signal lamp installed at the entrance of a tunnel, faults are often caused in the using process, but the reason is that the tunnel is cold and moist, and moisture in the air easily enters the interior of the signal lamp, so that electronic components in the signal lamp are short-circuited. In addition, the existing traffic signal lamp is generally fixedly installed at the top of the tunnel entrance by bolts, and once the traffic signal lamp fails, the traffic signal lamp is quite inconvenient for maintenance personnel.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model provides a traffic signal lamp for tunnel entrance.
The purpose of the utility model can be realized by the following technical scheme: a traffic signal lamp for a tunnel entrance comprises a tunnel body, wherein fixing seats are embedded in two sides of the tunnel body, a hanging rod is rotatably connected between the fixing seats, the hanging rod is arc-shaped and driven by a motor, and the motor is arranged in the fixing seat on one side;
a hanging bracket is sleeved in the middle of the hanging rod, a circle of limiting block is fixedly connected to the outer side of the hanging bracket, a placing box is fixedly connected to the lower portion of the hanging bracket, a traffic signal lamp body is installed in the placing box, and water absorbing particles are filled between the traffic signal lamp body and the placing box;
the placing box is hinged with a telescopic rod, and the free end of the telescopic rod is hinged on the tunnel body.
Furthermore, a plurality of through holes are formed in the box body of the placing box.
Further, the motor is a low-speed motor.
Furthermore, the inner side of the limiting block is attached to the outer side of the hanging bracket.
Further, the water-absorbing particles are calcium oxide or macromolecular water-absorbing resin.
The utility model has the advantages that:
1. the utility model discloses be provided with the case of placing in the traffic signal lamp outside, instead of directly hanging the traffic signal lamp in the tunnel entrance, place the incasement and fill simultaneously and have the granule that absorbs water, just so can absorb the moisture in the surrounding air, avoid moisture to enter into the traffic signal lamp inside and influence the use, prolonged the life of traffic signal lamp;
2. the utility model discloses a traffic signal lamp passes through the rotation of jib and the flexible of telescopic link can accomplish the lift, damages to the staff relatively more friendly when needing the maintenance at the traffic signal lamp body, and the security performance improves relatively.
Drawings
In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic structural view of another usage state of the present invention;
fig. 3 is a schematic view of the sectional structure of the sleeved state of the hanger and the suspension rod of the present invention.
In the figure: 1. a tunnel body; 2. a fixed seat; 3. a boom; 4. a motor; 5. a hanger; 6. a limiting block; 7. placing a box; 8. a traffic signal light body; 9. water-absorbing particles; 10. a telescopic rod.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1 to 3 in the attached drawings of the specification, a traffic signal lamp for a tunnel entrance comprises a tunnel body 1, fixing seats 2 are embedded in two sides of the tunnel body 1, a hanging rod 3 is rotatably connected between the fixing seats 2, the hanging rod 3 is arc-shaped, the hanging rod 3 is driven by a motor 4, and the motor 4 is arranged in the fixing seat 2 on one side;
a hanging bracket 5 is sleeved in the middle of the hanging rod 3, a circle of limiting block 6 is fixedly connected to the outer side of the hanging bracket 5, a placing box 7 is fixedly connected to the lower portion of the hanging bracket 5, a traffic signal lamp body 8 is installed in the placing box 7, and water absorbing particles 9 are filled between the traffic signal lamp body 8 and the placing box 7;
the placing box 7 is hinged with a telescopic rod 10, and the free end of the telescopic rod 10 is hinged on the tunnel body 1.
Furthermore, the box body of the placing box 7 is provided with a plurality of through holes.
Further, the motor 4 is a low-speed motor.
Further, the inner side of the limiting block 6 is attached to the outer side of the hanging bracket 5.
Further, the water-absorbing particles 9 are calcium oxide or high molecular water-absorbing resin.
The use principle is as follows:
the traffic signal lamp body 8 is installed inside placing case 7, places case 7 and hangs on jib 3 through gallows 5, because it has telescopic link 10 to articulate on four angles of placing case 7, and the free end of telescopic link 10 articulates on tunnel body 1. Thus, the placing box 7 can be stably hung and cannot shake.
And water-absorbing particles 9 are filled between the traffic signal lamp body 8 and the placing box 7. If the granules 9 that absorb water chose for use, the calcium oxide can be exothermic at the in-process that absorbs water, and it has a plurality of through-holes to open on the box of placing case 7, can in time spill the heat place the case 7 outside, can not influence traffic signal lamp body 8. If the water absorption particles 9 are made of high molecular water absorption resin, the high molecular water absorption resin absorbs water and expands, so that an expansion space is reserved between the placing box 7 and the traffic signal lamp body 8 during filling. The water absorption particles can absorb the moisture in the surrounding air, so that the moisture is prevented from entering the traffic signal lamp to influence the use, and the service life of the traffic signal lamp is prolonged.
If the traffic signal lamp body 8 has been bad and needs to be changed, perhaps absorb water granule 9 and reach when the saturation needs to be changed, just can starting motor 4, motor 4 is the low-speed motor, and slow pivoted in-process, telescopic link 10 slowly extends, through the self action of gravity who places case 7 and traffic signal lamp body 8, places case 7 and traffic signal lamp body 8 and is in vertical state always. The height of the placing box 7 and the traffic signal lamp body 8 is reduced, the maintenance is relatively friendly to workers, and the safety performance is relatively improved.
The foregoing is merely exemplary and illustrative of the structure of the invention, and various modifications, additions and substitutions as described in the detailed description may be made by those skilled in the art without departing from the structure or exceeding the scope of the invention as defined in the claims.
