Description

Ground signal light for pedestrian crossing

technical field

The utility model relates to a ground signal lamp for pedestrian crossings, which belongs to the technical field of piezoelectric material application and traffic equipment.

Background technique

In modern urban life, the pace of life is gradually accelerating, and people's lifestyles are also quietly changing. Mobile phones have almost become a necessity for everyone, but it also makes some people develop bad living habits and form a kind of dependence on them. Even when passing a crosswalk, they often look down at their mobile phones and fail to pay attention to the instructions of traffic lights. Dangerous. In addition, in some bad weather, when passing a pedestrian crossing, it is difficult to observe the display of the signal lights on the opposite side of the road, and it is also prone to danger.

Piezoelectric ceramics have been developed to a certain extent in the field of piezoelectric energy conversion. The use of piezoelectric power generation modules can completely realize the self-production and self-use of electric energy, energy saving, high efficiency and environmental protection.

Utility model content

The utility model is to provide a pedestrian crossing ground signal lamp. Utilize the pressure exerted on the piezoelectric power generation module under the crosswalk by people or vehicles passing through the crosswalk. When the piezoelectric power generation module is subjected to external force, it will generate electric energy and store it in a large-capacity battery for use by ground signal lights and alarms. Can be used by other equipment. It is a pedestrian crosswalk ground signal light in the self-produced and self-use mode of electric energy. It can make some pedestrians observe the display of the signal light when they pass the crosswalk with their heads down or encounter bad weather, and remind pedestrians to pay attention to traffic safety. , to prevent accidents.

For realizing the above object, the utility model adopts the following technical solutions:

The utility model is a ground signal light for a pedestrian crossing, which comprises a ground signal light, a piezoelectric power generation module, a signal synchronization sensor, a controller, an alarm, and a large-capacity battery; the large-capacity battery is arranged on the sidewalks on both sides; The signal lamps are connected with the signal synchronization sensor through the line 1, the signal synchronization sensor is connected with the controller at the same time, and the controller is connected with the alarm.

The signal lights on the ground use non-motor vehicle signal lights for pedestrians (two-in-one). The top of the signal lights on the ground is covered and sealed with a transparent pressure-resistant tempered glass cover. The plane size of the signal lights on the ground is 1900mm×850mm. The size specification is 2500mm×1200mm, and the distance L1 between the side edge of the transparent compressive tempered glass cover plate close to the center line of the road and the extension line of the dividing line between the non _- motor vehicle lane and the motor vehicle lane is 30-50cm.

In the design of this scheme, the piezoelectric power generation membrane block is composed of an upper rubber pad, a lower rubber pad, and a piezoelectric unit power generation module; each piezoelectric unit power generation module is arranged between the upper rubber pad and the lower rubber pad, and the plug-in staggered arrangement, and each piezoelectric unit power generation module is independent of each other.

The piezoceramic is made in the form of a conical side and arranged in a conical protective shell.

The beneficial effects of the utility model are:

First, the generated electric energy is stored in a large-capacity battery for use by ground signal lights and alarms, and the surplus electricity can be used for other equipment. One large-capacity battery is arranged on the sidewalks on both sides, and the large-capacity batteries on both sides respectively collect the electric energy produced by the half of the piezoelectric unit power generation module close to each side, which is convenient for ground signal lights, alarms and other equipment on both sides. use. The signal light on the ground is connected with the conventional signal light through line 1 with a signal synchronization sensor to ensure that the display of the signal light is synchronous. The signal synchronization sensor is connected with the controller at the same time. The controller can set the start signal from the signal synchronization sensor. After receiving the start signal, the controller controls the alarm to make a "didi" sound to remind pedestrians to pay attention to the traffic again. Safety.

Second, the signal lights on the ground use pedestrian and non-motor vehicle signal lights (two-in-one), which is more convenient and efficient to direct traffic. The plane size specification of the ground signal light is 1900mm×850mm, which is about (1.5×1.5) times the size specification of the conventional pedestrian non-motor vehicle signal light (two-in-one), and the ground signal light with larger size can play a more eye-catching effect. The size of the transparent pressure-resistant toughened glass cover is 2500mm×1200mm, which is enough to cover the signal lights on the ground. According to relevant urban traffic road regulations, it can be seen that the width of pedestrian crossings is generally 3-5m, and the minimum width of non-motor vehicle lanes is generally 4.5m. The length of the ground signal light and the transparent pressure-resistant tempered glass cover plate cannot be greater than the width of the pedestrian crossing. At the same time, based on the consideration of the eye-catching effect of the ground signal light, it is more appropriate to use such a size for the ground signal light and the transparent pressure-resistant tempered glass cover plate. The distance L1 between the side edge of the transparent pressure _- resistant tempered glass cover plate close to the road center line and the extension line of the dividing line between the non-motor vehicle lane and the motor vehicle lane is 30-50cm; in order to prevent vehicles from above the ground signal lights After the situation that affects pedestrians’ observation of ground signal lights, when arranging and installing ground signal lights, its installation position should be as far away from the motor vehicle lane as possible, but considering the width of non-motor vehicle lanes and the needs of pedestrians waiting, this distance should not be too large. Therefore, L1 is set as _30-50cm .

Thirdly, each piezoelectric unit power generation module is arranged between the upper rubber pad and the lower rubber pad, and the upper rubber pad and the lower rubber pad play a role in protecting the piezoelectric unit power generation module. The piezoelectric unit power generation module adopts a plug-in staggered arrangement, which increases the possibility of the piezoelectric power generation module receiving external forces and exerts its power generation function to a greater extent. Each piezoelectric unit power generation module is independent of each other. When a problem occurs in one individual, the others will not be affected, so as to ensure the normal operation of the entire piezoelectric power generation module.

Fourth, the piezoelectric ceramics are made in the form of a conical side and arranged in a conical protective shell. When the piezoelectric unit power generation module is subjected to external force, the conical metal block moves downwards and squeezes the piezoelectric ceramics, which can be replaced. Maximize contact area.
