Description

Eco-friendly street lights with photoresistor-controlled switches powered by solar and wind energy

technical field

The utility model relates to a green environment-friendly street lamp which is powered by solar energy and wind energy and whose switch is controlled by a photosensitive resistor.

Background technique

Existing street lamps are mainly composed of lampposts, street lamp flanks, bulbs and power supply lines. The lighting network is formed by connecting each other through parallel circuits, and the power supply department uniformly supplies power and controls the switches. The main disadvantages of this kind of street lamp are: 1. The energy source required for lighting is only electric energy, which is mainly converted by the power generation department through burning coal and other non-renewable resources, which not only causes excessive exploitation of resources, but also exacerbates the shortage of resources. problems, and the sulfur dioxide, carbon monoxide, nitrogen monoxide and solid dust generated during the power generation process have caused serious environmental pollution problems; 2. The connection line is long and complicated, requiring too many wires, and the long-term underground environment makes it Corrosion is serious, resulting in waste of wires, and at the same time, in the process of long-distance power transmission, the power loss is too large; 3. The circuit connection method is a parallel circuit, which can only be switched by the power supply department, which is not selective and has poor anti-interference. If the main line If a fault occurs, the entire lighting system will be paralyzed; 4. It is inconvenient to overhaul, maintain and add. Most of the circuits that need to be repaired are buried underground. original circuit.

Contents of the invention

The purpose of this utility model is to provide a self-regulating green environment-friendly street lamp that is powered by solar energy and wind energy and controlled by a photoresistor, which can overcome the above-mentioned shortcomings of the prior art.

An environmentally friendly street lamp powered by solar and wind energy with a photoresistor-controlled switch, which has a lamp post, a street lamp flank, and a bulb, and is characterized in that the lamp post is a hollow lamp post, and a small generator and a battery are installed inside it; There is a wind cup on the top of the hollow lamp post, which has three spoon-shaped wind wings, and the base of each wind wing strut is connected to the bearing. The bearing is connected with the power generation coil of the small generator through the rotating shaft. The wire is connected to the positive and negative poles of the battery; there is a solar panel on the upper part of the wind cup, and the solar panel is also connected to the positive and negative poles of the battery through the wire; The light bulb and lampshade are installed on the side of the hollow street lamp away from the end of the hollow lamp post, and the photoresistor is installed on the top of the lampshade.

The utility model has the advantages of: 1. Environmental protection, its energy comes from solar energy and wind energy. Coal and other non-renewable resources; 2. The street lamps are independent of each other and do not need to be connected by lines, which avoids the cumbersome process of erecting and maintaining lines, and also avoids the safety hazards brought by a large number of lines to pedestrians, and also reduces wind and lightning. Interference caused by weather and other factors to lighting lines; 3. Each street lamp has its own power supply and photosensitive switch, which can be automatically adjusted according to changes in the external environment, with strong selectivity and no interference from other street lamps; 4. Maintenance and addition are easier OK, when a fault occurs, the pertinence of the maintenance work is greatly enhanced, and it will not cause any inconvenience to the road and traffic.

Detailed ways

The utility model has a light bulb 5, a lamp post, and a street lamp flank, and is characterized in that the lamp post is a hollow lamp post 7, and a small generator 2 and a storage battery 3 are installed inside it; the top of the hollow lamp post 7 has a wind direction cup 1 , it consists of three spoon-shaped wind wings, the base of each wind wing strut is connected to the bearing 9, the bearing 9 is connected with the power generation coil of the small generator 2 through the rotating shaft, and the electric energy output end of the small generator 2 is connected to the storage battery through a wire The positive and negative poles of 3 are connected; there is a solar panel 4 on the top of the wind cup 1, which is inclined upward and forms an angle of 10-30° with the horizontal plane, so as to receive sunlight to the maximum. The solar panel 4 is connected to the positive and negative poles of the battery 3 through wires; the upper side of the hollow lamp post 7 is connected to a hollow street lamp flank 8, and its interior communicates with the interior of the hollow lamp post 7; the bulb 5 and the lampshade are installed on the hollow street lamp flank 8 The photoresistor 6 is installed on the top of the lampshade away from the end of the hollow lamp post 7 . At the same time, the solar panel 4 is located on the upper part of the hollow lamppost 7, which can effectively prevent rainwater from entering the hollow lamppost 7, thereby avoiding the corrosion of the circuit by rainwater and the like. Bulb 5 is installed on the end of hollow side wing 8 away from hollow lamp post 7, because it is far away from wind cup 1, and there is lampshade on it, therefore can effectively prevent the rotation of wind cup 1 from affecting its illumination light. The photosensitive resistor 6 is installed on the top of the lampshade to reduce the interference of the street light on its circuit operation; the resistance value of the photosensitive resistor 6 increases rapidly when the light reaches a certain intensity, and the resistance value of the photosensitive resistor 6 decreases rapidly when the light is lower than the intensity .

When in use, in the case of wind, the wind in any direction can drive the wind cup 1 to rotate, and the rotation of the above wind cup 1 will drive the small generator 2 to work to generate electric energy, and the generated electric energy is transmitted to the battery 3 through wires for chemical stored in the form of energy; in the case of sunlight, the solar panel 4 will absorb the energy in the sunlight to generate electrical energy, and the generated electrical energy is transmitted to the storage battery 3 through wires to be stored in the form of chemical energy; when the light drops to a certain intensity, the photoresistor The resistance value of 6 decreases sharply, the circuit is connected, the storage battery 3 converts chemical energy into electrical energy output, supplies the light bulb 5 to make it glow, and starts lighting work; when the light rises to a certain intensity, the resistance value of the photoresistor 6 rises sharply, and the circuit is cut off Open, storage battery 3 stops supplying power, and bulb 5 stops working.

After the utility model is installed, it can work automatically according to the external conditions.

The parts relevant to the circuit of the utility model have small generator 2, accumulator 3, solar panel 4, bulb 5, photoresistor 6, they all have commercially available, and circuit is all known, and the relation between them has been explained, Therefore the circuit diagram of the present utility model just needn't draw.
