Description

Protection device for municipal street lamp

Technical Field

The utility model relates to a municipal works lighting apparatus technical field, concretely relates to protector for municipal street lamp.

Background

In order to improve the safety of people and vehicles on roads, street lamps are usually arranged on two sides of the roads. The Chinese street lamp appeared in 1843 in the Shanghai for the first time, and the street lamp was ignited by a kerosene lamp, and then changed into a gas street lamp later. In 1879, Shanghai came to the first lamp in China.

With the progress of the times, the scientific technology is continuously pushed out and new, and the total number of the Chinese street lamps is 9186356. The annual power consumption of municipal lighting accounts for about 4-5% of the total power generation in China, and is equivalent to the annual power generation capacity after the hydropower engineering of the three gorges is put into operation. Street lamps will be the largest area of application, reaching $ 15 billion in 2011 and $ 18 billion in 2012 is expected. In 2012, with the pressure of energy conservation and emission reduction, the acceptance degree of the LED street lamp is greatly improved. The popularization of the LED street lamp is one of the main measures of energy conservation and emission reduction plans.

Among the prior art, municipal street lamp all adopts higher cavity tubulose lamp pole (2) in order to enlarge the illumination zone, because lamp pole (2) are longer, and the focus is higher, and shock resistance is weak, is extremely easily knocked down by the car in the area that the driving accident is frequently sent. The street lamp after being toppled over not only can cause the hindrance effect to the vehicle traveling to bury in the street lamp after toppling over and the power supply line ground connection in hollow lamp pole (2), probably arouses pedestrian's incident such as electric shock very much.

In view of this, a protection device for municipal street lamp is needed to avoid toppling over of municipal street lamp due to the striking of vehicle.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects of the prior art, the utility model aims to provide a protection device for municipal street lamp can protect the municipal street lamp from falling down due to the impact of vehicle.

In order to realize the above object, the technical scheme of the utility model is that: a protector for a street light comprising: the lamp comprises a base, a lamp post, a protective shell and a bearing sleeve, wherein the base is fixedly installed on the ground, the lamp post is fixedly installed on the base, the bearing sleeve is sleeved on the outer wall of the lamp post and is fixedly connected with the protective shell through a connecting frame, a groove is formed in the inner wall of the protective shell, and a buffering air bag external member is fixedly installed in the groove.

Further, the cushion airbag kit includes: the gas generator is fixedly arranged on the inner wall of the groove, and the gas bag assembly is communicated with the gas generator.

Further, protective housing outer wall fixed mounting has collision sensor, protective housing inner wall fixed mounting has the controller, collision sensor with control, gas generator electric connection.

Furthermore, the bottom of the inner wall of the base is provided with a sliding groove matched with the protective shell.

Furthermore, a plurality of rubber bulges are arranged on the outer wall of the protective shell.

Has the advantages that:

(1) the rubber bulge arranged on the protective shell can buffer part of impact force brought by an impacting object due to deformation;

(2) when the collision object collides against the protective shell, the protective shell can rotate relative to the lamp post by means of the impact force brought by the collision object, so that the impact direction of the collision object is changed.

(3) When the impact force of the collision object is too large, even the protective housing deforms, the buffering air bag sleeve piece starts up, and the lamp pole is prevented from being extruded due to the deformation of the protective housing, so that the displacement or deformation is caused.

FIG. 2 is a schematic perspective view of a protective device for a municipal street lamp according to the present invention, state 2;

FIG. 3 is a perspective view of the protective device base for a street lamp according to the present invention;

the labels in the figure are: the lamp comprises a base 1, a lamp post 2, a protective shell 3, a bearing sleeve 4, a sliding groove 11, a connecting frame 31, a groove 32, a collision sensor 33, a controller 34 and a rubber bulge 35.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

As shown in the figure, the utility model discloses a protector for municipal street lamp, include: base 1, lamp pole 2, protecting sheathing 3, bearing

sleeve

4, 1 fixed mounting of base is in ground, 2 fixed mounting of lamp pole are in on the base 1, bearing sleeve 4 cup joints 2 outer walls of lamp pole, bearing sleeve 4 through link 31 with 3 fixed connection of protecting sheathing, recess 32 is seted up to 3 inner walls of protecting sheathing, fixed mounting has buffering gasbag external member in the recess 32.

In this embodiment, the cushion airbag kit includes: the gas generator is fixedly arranged on the inner wall of the groove 32, and the gas bag assembly is communicated with the gas generator.

In this embodiment, the outer wall of the protective housing 3 is fixedly provided with a collision sensor 33, the inner wall of the protective housing 3 is fixedly provided with a controller 34, and the collision sensor 33 is electrically connected with the control device and the gas generator.

In this embodiment, the bottom of the inner wall of the base 1 is provided with a sliding groove 11 matched with the protective housing 3.

In this embodiment, the outer wall of the protective casing 3 is provided with a plurality of rubber protrusions 35.

The working principle is as follows:

in the actual working process, when the automobile is out of control and collides with the street lamp, the automobile can collide with the street lamp post 2 from any angle in the collision process, the protective shell 3 is fixedly connected with the bearing sleeve 4 through the connecting frame 31, and then the whole of the protective shell 3 and the bearing sleeve 4 is driven to rotate around the lamp post 2 by the impact force and the friction force caused by the automobile collision. Be provided with a plurality of rubber bumps 35 on protective housing 3 outer wall, because the deformation of rubber bump 35 to certain cushioning effect has been played, because protective housing 3 can rotate for lamp pole 2 again, has removed the impact force that the car clashes and brings by a wide margin.

When the impact force brought by the automobile collision is too large, the impact sensor 33 transmits the detected impact force value to the controller 34, the real-time data detected by the impact sensor 33 is compared with preset data and then the command gas generator is commanded to generate gas, so that the gas bag is rapidly expanded, the space between the protective shell 3 and the lamp post 2 is filled, and the lamp post 2 is prevented from being extruded due to the deformation of the protective shell 3 inverted due to the too large impact force. Meanwhile, most of the impact force can be dissolved due to the buffering effect of the air bag.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and all modifications, equivalents, improvements and the like that are within the spirit and principle of the present invention should be included in the scope of the present invention.
