Description

A passive luminous street sign

technical field

The utility model relates to a road indicating street sign, in particular to a passive luminescent street sign.

Background technique

Road information signs are widely used in urban road instructions to provide people with road names and road directions. However, at present, the road signs set on the road are mostly sprayed with fluorescent powder on the signboard. At night, it is necessary to use the reflected light of the fluorescent powder to see the road information clearly. This kind of signboard can be seen clearly during the day, but it appears blurred at night. Clearly, if the driver does not see the instructions on the sign at this time, it will cause more walking due to wrong roads, which will not only waste energy virtually, but also increase potential traffic risk factors. Although there are many solar luminous street signs at present, the power generation of solar cells per unit area often does not reach the designed value, which reduces the effective utilization of solar panels and causes a waste of resources invisibly; And the noise sources around the road will generate noise pollution, which reduces the quality of daily life of nearby residents.

Contents of the invention

The utility model aims at the problem that street signs are not easy to see clearly at night, and proposes a passive luminous street sign, which combines solar energy, noise energy and low-power LEDs, reasonably designs energy sources, and solves the problem of nighttime indication clarity.

The technical scheme of the utility model is: a passive luminescent road sign, including the road information sign body, and also includes a solar power generation system, a noise generator and a storage battery. The road information on the sign body is composed of LED lights, and the solar energy After the solar panel and the noise generator in the power generation system are connected in parallel, the output is connected to the storage battery, and the storage battery supplies power to the sign body through the light control switch, and is arranged on the top of the road information sign body.

In the solar power generation system, a convex lens is arranged above the solar panel, and the convex lens is supported by two hydraulic steel rods that can be stretched in length. The temperature sensor installed at the solar panel transmits the collected solar panel temperature to the processor, and the processor The controller controls the lifting device on the hydraulic steel rod support.

The noise generator is arranged at the bottom of the sign body, and is connected in parallel with the solar panel to form an energy supply unit of the storage battery.

The beneficial effects of the utility model are: the passive luminous street sign of the utility model has high working stability and can provide pedestrians with clear road information at night; the concentrating effect of the convex lens strengthens the intensity of the sun's rays and increases the power generation of solar cells per unit area Quantity; the noise generator set at the bottom of the sign can use the noise generated by passing vehicles on the road or surrounding noise sources to generate electricity, and turn harmful noise into electrical energy that can be stored by the storage battery for use by the LED lights. To achieve energy-saving effect.

Detailed ways

As shown in Figure 1, a schematic diagram of the structure of a passive luminous street sign, a passive luminous street sign, including a road information sign body 1, a solar power generation system 3, a noise generator 4 and a storage battery 5, and the road on the sign body 1 The information consists of 2 arrays of LED lights. The connection schematic diagram of each part as shown in Figure 2, the solar battery panel and the noise generator 4 in the solar power generation system 3 are in parallel relationship, the solar panel converts the sunlight energy received into electric energy, and the noise generator 4 collects the road The surrounding noise is converted into electrical energy, and the two together provide storage battery 5 with stored electrical energy. At night or when the light is dark, the light control switch 6 is closed, so that the series loop formed by the storage battery 5 and the LED light 2 is connected, and the LED light 2 works normally, clearly indicating road information for people.

As shown in Figure 3, the structural diagram of the solar power generation system is set on the top of the road information sign body 1, and a convex lens 10 is set at a certain distance above the solar panel. . The temperature sensor installed at the solar panel transmits the collected temperature of the solar panel to the processor, and the processor controls the lifting device on the support pole. At the beginning, the convex lens is at position a. If the temperature exceeds the set value, the processor will command the hydraulic lifting device 9 to operate at the same time, so that the distance between the convex lens 10 and the solar panel will change, and the position will change from a to b, reducing the light-gathering effect of the convex lens. , weaken the intensity of light at the solar panel, thereby reducing the surface temperature of the solar panel. When the temperature drops to a set value, the processor 7 instructs the lifting device 9 to operate simultaneously again, so that the light-gathering effect of the convex lens 10 is strengthened again to increase the solar energy. The power generation efficiency of the panel, so reciprocating, makes the power generation efficiency of the solar panel maintain at a high level; in addition, a rotating device is installed at the bottom of the solar panel, and the rotational angular speed of the device is set to the rotational angular speed of the sun relative to the earth, and the rotational angular speed is selected as 360°/ 24h=15°/h; In order to avoid the energy loss and waste caused by the idling of the rotating device, you can look up the sunshine schedule in the area where the passive luminous street signs are installed, and adjust the rotating device so that the solar panels can operate at the time when the sun is strongest The section has the ability to track the sun. In addition, the rotating device contains a sunlight intensity detector. When the sunlight intensity does not reach the set value, the rotating device will stop working. For example, 9:00 to 15:00 in area A is a time interval with strong sunlight intensity, and the rotation angle of the rotating device can be adjusted to (15-9)×15°=90°. By using the rotating device, the ability of the solar panel to track the sun can be basically realized, so that the solar panel is kept perpendicular to the sun's rays, and the power generation efficiency of the solar panel is improved.
