Description

Technical Field

[0001] The utility model relates to the technical field of street lamp posts, in particular to a safety street lamp post which can prevent a lamp head from falling. Background Art

[0002] Street lamps play a vital role in urban lighting systems. However, traditional street lamp posts have certain safety hazards in the long-term use process, one of the most prominent problems is the lamp head falling. This situation may lead to serious consequences, not only causing damage to street lamp equipment, but also causing harm to pedestrians and lamp heads, and even causing traffic accidents.

[0003] The fixing structure of traditional street lamp poles may be loose or corroded, causing the lamp head to loosen or fall off under the influence of wind, rain or other external forces, becoming a potential source of damage. The falling lamp head may not only damage the street lamp pole itself, but also affect surrounding buildings, transportation facilities, etc., increasing the cost of repair and maintenance.

[0004] Falling lamp heads may cause injuries to pedestrians and lamp heads, especially at night when visibility is low and accidents are more likely to occur. Although today's street lamp posts have been improved to a certain extent, there are still some unresolved problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a safety street lamp post which can prevent the lamp head from falling.

[0006] The technical solution of the utility model is: a safety street lamp post capable of preventing a lamp holder from falling, comprising a post body, a lamp holder fixedly connected to the post body via a lamp arm, a recovery component arranged at the upper half of the post body, and an anti-collision component arranged on the outer surface of the lamp holder; an I-shaped protrusion is arranged at one side where the lamp arm is fixedly connected to the post body, an I-shaped groove for mounting and fixing the I-shaped protrusion is arranged at the top of the post body, and a mounting groove for plugging and mounting with the end of the lamp arm is arranged at the lamp holder;

[0007] The recovery component includes a maintenance box arranged on the pile body, a one-way winch fixedly arranged on the maintenance box, a motor fixedly arranged on the maintenance box and providing power for the one-way winch, an elastic baffle arranged on the side wall of the pile body, and a looseness sensing component arranged on the lamp head; the lamp head and the one-way winch are connected by a steel rope; the motor is controlled to work by monitoring the looseness sensing component, thereby driving the one-way winch to recover the lamp head.

[0008] Description: The design of the maintenance box facilitates the inspection and maintenance of the lamp pole and lamp holder, avoiding secondary damage to surrounding facilities caused by hanging lamp holders; the clamping installation reinforcement method is adopted to ensure the stability of the connection between the pole body and the lamp arm, and the lamp arm and the lamp holder. The design of the safety street lamp pole takes into account practicality, safety and durability, which can reduce maintenance costs and extend the service life of street lamps while ensuring public safety.

[0009] Furthermore, the looseness sensing component includes an acceleration sensor arranged on the lamp head, a pressure sensor arranged at the connection between the lamp arm and the lamp head, a camera arranged on the pile body, and a wireless communicator arranged on the pile body.

[0010] Description: The loose sensing component can monitor and warn the loose state of the lamp holder in real time. The acceleration sensor can detect slight movement of the lamp holder due to vibration or other reasons, and the pressure sensor can monitor the pressure change at the connection between the lamp arm and the lamp holder to determine whether there is looseness. If the pressure change fluctuates too much, the camera can provide on-site images to facilitate further confirmation of the looseness. The wireless communicator can transmit this information to the maintenance personnel in real time so that timely maintenance can be carried out to ensure the stability and safety of the lamp holder. Such a setting can greatly improve the efficiency and safety of lamp holder maintenance and reduce the potential dangers and maintenance costs caused by loose lamp holders.

[0011] Furthermore, a shock-absorbing layer is arranged on the outer side wall of the lamp holder, and an anti-collision rubber layer is arranged on the outer side wall of the pile body.

[0012] Description: The shock-absorbing layer can provide a buffering effect when the lamp head is hit, reducing the risk of damage. The anti-collision rubber layer can absorb the impact energy when the pile body is hit, disperse the impact force, reduce the damage to the structure, and thus improve the overall safety performance; the design of the anti-collision rubber layer helps to increase the friction of the pile body, preventing it from sliding or flipping when it is hit, thereby improving the overall stability; because the shock-absorbing layer and the anti-collision rubber layer can reduce the damage to the lamp head and the pile body, the need for repair and replacement is reduced, thereby reducing the long-term maintenance cost.

[0013] Furthermore, an anti-collision component is also provided on the outer surface of the lamp holder, and the anti-collision component includes an electrically controlled inflatable component provided on the lamp holder, and an air bag connected to the electrically controlled inflatable component through a conduit;

[0014] The outer surface of the lamp head is surrounded by a loading groove, and a flexible baffle is arranged at intervals at the opening of the loading groove, and one side of the flexible baffle is connected to the edge of the loading groove through a damping shaft; the airbag is embedded in the loading groove;

[0015] The electrically controlled inflation assembly includes a shell, an electronic trigger arranged inside the shell, and a filter plate arranged outside the electronic trigger; a gas generating agent is filled between the electronic trigger and the filter plate; and a one-way pressure valve is arranged on the airbag.

[0016] Description: Through the precise control of the electronic trigger, it can be ensured that the airbag is inflated only when necessary, avoiding unnecessary consumption and maintenance costs; the gas generator is filled between the electronic trigger and the filter plate, so that gas can be quickly generated to fill the airbag when needed, while keeping the system compact and safe; the presence of the filter plate can prevent impurities in the gas generator from entering the airbag, ensuring the cleanliness and normal operation of the airbag; the one-way pressure valve on the airbag ensures that the gas will not flow back when the airbag is inflated, and at the same time ensures that the inflation degree of the airbag can achieve the best protection effect and avoid excessive inflation of the airbag. Inflation causes airbag damage or reduced protective effect; use trigger-type safety airbag to protect lamp head and avoid collision damage. Compared with normalized inflation airbag, the advantage is that it avoids the large wind resistance caused by setting normalized inflation airbag to lamp head. Wind force is also one of the causes of lamp head falling. The setting of trigger-type safety airbag and cargo slot can avoid affecting the light of lamp head. Moreover, street lamp pole is exposed to the external environment. Normalized inflation airbag is easily affected by climate, resulting in leakage or damage, affecting the anti-collision effect. Trigger-type safety airbag can better avoid this problem.

[0017] Furthermore, a spare bulb is arranged on the lamp arm; the electronic trigger adopts an electric trigger detonator, and the gas generating agent adopts sodium azide.

[0018] Note: After the lamp head falls, the spare bulb is turned on as a temporary emergency measure to avoid traffic accidents caused by darkness. Sodium azide, as a commonly used detonator, is widely used in airbag systems. It can quickly inflate the airbag, thereby protecting objects in contact with the airbag from damage; the electric trigger detonator can ensure that the gas generator is accurately activated when the lamp head falls, providing a consistent and reliable response time; sodium azide, as a gas generator, can generate a large amount of gas in a short time, which is very effective for quickly inflating airbags; compared with other gas generators, sodium azide is usually lower in cost.

[0019] Furthermore, a rain shield capable of extending above the lamp head is provided on the top of the lamp arm.

[0020] Description: Rain shields can protect lamps from direct impact of rain, reducing the risk of circuit short circuit or damage caused by moisture; in severe weather conditions, rain shields can reduce the risk of lamps being blown off by the wind, avoiding safety hazards; with rain shields, maintenance personnel can operate more safely and conveniently when repairing lamps, reducing the difficulty and cost of repairs.

[0021] The beneficial effects of the utility model are as follows: the utility model sets a recovery component, utilizes a one-way winch and a motor, and can promptly recover the lamp head when there is a risk of loosening or falling off of the lamp head, thereby preventing it from falling and causing personal injury or property loss, and facilitating subsequent maintenance work by staff; the looseness sensing component can monitor and warn the loose state of the lamp head in real time, and timely discover and deal with potential safety hazards; the card connection design of the I-shaped protrusion and the I-shaped groove between the lamp arm and the pile body, and the plug-in installation of the lamp head and the end of the lamp arm, all provide a stable connection method, thereby enhancing the structural stability of the entire street lamp; the setting of the anti-collision component can absorb the impact force generated by the collision of the lamp head, protect the safety of surrounding facilities and the lamp head, and also protect the street lamp itself from being easily damaged by collision, thereby reducing maintenance costs.
