As shown in fig. 4 and 7, the toppling detection unit 6 includes:

a mounting post 61 disposed within the light pole 1;

a heavy ball 64 located within the light pole 1 and suspended below the mounting pole 61 by a lifting rope 62; and

a plurality of collision detectors 63 which are uniformly arranged on the inner wall of the lamp post 1, wherein the plurality of collision detectors 63 are distributed in a central symmetry manner by taking the central axis of the lamp post 1 as the center;

the collision detector 63 may employ a pressure measuring instrument such as a pressure sensor, a pressure gauge, or the like.

When the street lamp is inclined in any direction, the heavy ball 64 collides with one or more collision detectors 63, the collision detector 63 collided by the heavy ball 64 generates a pressure detection signal and transmits the detection signal to the control unit 7, and the control unit 7 controls the control valve 32 to be opened according to the detection signal so as to expand the air bag 34.

Considering that the lamp post 1 is generally inclined, not absolutely vertical, and inclined at a certain angle after the street lamp is actually installed, and the street lamp is inclined when suffering from strong wind blow or impact, beat and shake of human body, and the inclination does not cause the street lamp to topple, therefore, in order to prevent the airbag 34 from expanding by mistake when the inclination occurs, the street lamp should be inclined at a certain angle, and then the heavy ball 64 collides with the collision detector 63;

in addition, in order to allow a sufficient inflation time for the airbag 34 to inflate, the street lamp inclination angle α at which the weight balls 64 collide with the collision detector 63 cannot be made too large, preferably 10 ° α or more and 30 ° or less, as shown in fig. 7.

The tilt detection unit 6 may be configured as described above, and may be a detection device capable of sensing whether or not an object is tilted, such as a gravity sensor, a gyroscope, an attitude sensor, and an acceleration sensor.

When the toppling detection unit 6 is designed by the structure shown in fig. 4 and 7, the street lamp toppling protection device may further include a toppling delay unit capable of delaying the toppling speed of the street lamp, so as to further ensure that the air bag 34 has enough time to expand and reduce the impact on the ground or objects on the ground when the street lamp is toppled over the ground.

As shown in fig. 4 and 6, the pour delaying unit includes:

the lamp post comprises at least three gas injection holes 51 which are uniformly distributed at the upper part of the lamp post 1, wherein the gas injection holes 51 are centrally and symmetrically distributed by taking the central axis of the lamp post 1 as the center, and the central axis of the gas injection holes 51 is vertically intersected with the central axis of the lamp post 1;

the number of the second gas pipes 52 is equal to that of the air injection holes 51, and each air injection hole 51 is communicated with the gas storage container 31 through one second gas pipe 52; and

the flow controller 53 is arranged on each second air delivery pipe 52 and is used for controlling and regulating the flow of the air flowing through the second air delivery pipe 52;

in order to facilitate the communication between the second air pipe 52 and the air storage container 31, the second air pipe 52 and the air storage container 31 can be connected through a pipe divider 4, as shown in fig. 4, the pipe divider 4 is a hollow shell, one end of the pipe divider 4 is communicated with the air storage container 31, and the other end of the pipe divider 4 is communicated with a plurality of second air pipes 52 (fig. 4 and 7 show four air injection holes 51 and four second air pipes 52).

When the toppling detection unit 6 is designed by adopting the structures shown in fig. 4 and 7, the control unit 7 can analyze and judge the toppling direction of the street lamp according to the detection signal obtained by the toppling detection unit 6, then the control unit 7 controls the corresponding flow controller 53 to adjust the flow rate of the gas flowing through the second gas conveying pipe 52, when the street lamp does not topple, the flow controller 53 does not act, the flow rate of the gas flowing through the second gas conveying pipe 52 is zero, after the flow controller 53 is opened and adjusts the flow rate of the gas flowing through the second gas conveying pipe 52, the high-pressure gas or the liquefied gas in the gas storage container 31 is rapidly sprayed out of the gas spraying holes 51 through the second gas conveying pipe 52, the sprayed gas generates a recoil acting force on the street lamp, as shown in fig. 11, the force F is the resultant force of the force F1 and the force F2, and the force F1 and the force F2 are the recoil acting force of the gas sprayed out of the two gas spraying holes 51 on the street lamp, as long as the The air injection holes 51 can play a role in delaying the toppling of the street lamp, the larger the resultant force is, the more obvious the toppling delaying effect on the street lamp is, but the resultant force cannot be too large, otherwise, the street lamp can topple in the opposite direction, namely, the toppling direction of the street lamp is the same as the direction of the resultant force, and therefore the street lamp is toppled in an accelerated manner and is unreliated.

The control unit 7 adjusts the air injection flow of the second different air delivery pipes 52 by controlling the different flow controllers 53, so as to adjust the magnitude of the recoil force generated by the air injected from the different air injection holes 51 on the street lamp, and then adjust the resultant force direction of the recoil force to be matched with the toppling direction of the street lamp, thereby achieving the purpose of delaying the toppling of the street lamp.

In order to ensure that the control unit 7 can accurately analyze and judge whether the street lamp topples and the toppling direction of the street lamp according to the detection signal acquired by the toppling detection unit 6, the number of the collision detectors 63 cannot be too small, and the collision detectors 63 are preferably arranged next to each other, that is, the distance between two adjacent collision detectors 63 which are distributed in a central symmetry manner and shown in fig. 4 and 7 is zero, so that no matter which direction the street lamp topples, the collision detectors 63 collide with the heavy ball 64, and the control unit 7 can calculate the tilting direction of the street lamp according to the magnitude of the collision signals fed back by the collision detectors 63 at different positions.

In order to facilitate the installation and arrangement of the inflation unit, the toppling delay unit, the toppling detection unit 6 and the control unit 7 in the lamp pole 1, the lamp pole 1 may be designed in a multi-section manner, as shown in fig. 4 and 5, the lamp pole 1 is divided into a first pole section 11, a second pole section 12, a third pole section 13 and a fourth pole section 14 from top to bottom, and two adjacent pole sections are detachably and fixedly connected.
